JP7759100B2 - Air Stretch Exercise Device - Google Patents

Description

The present invention relates to a sheet-type air stretching exercise device that can be placed on a substantially horizontal surface such as the floor or a bed, allowing the user to lie on their back and perform stretching exercises, and also allowing the user to sit on the seat and press against the area to be treated.

In recent years, people have fewer opportunities to move their bodies and often remain in the same position for long periods of time. As a result, the muscles and tendons of the body often become contracted and stiff. Devices that can perform stretching exercises on such bodies (treatment areas) are available on the market. Patent Document 1, for example, discloses an exercise machine that can perform stretching exercises on treatment areas such as the back from the shoulders to the waist and buttocks. The stretching exercise machine in Patent Document 1 is a seat-type machine in which the user lies supine on the seat and stretches the back, buttocks, etc.

Devices that use airbags to apply pressure to the user's treatment area are also commercially available. A device that uses airbags to apply pressure to leg areas such as the thighs and calves is disclosed, for example, in Patent Document 2. Patent Document 2 discloses a device that includes a belt-shaped first leg covering portion that can be wrapped around the thighs and a belt-shaped second leg covering portion that can be wrapped around the calves (see, for example, Embodiment 3, Figure 7, etc.).

Patent No. 7054919 JP 2018-183282 A

Patent Document 1 discloses a device that allows sufficient stretching exercises for the shoulders, back, waist, and other areas of the back, as well as the buttocks, and provides a high stretching effect.

Patent Document 2 describes a cumbersome device that requires wrapping a first belt-shaped leg covering portion around the thighs and a second belt-shaped leg covering portion around the calves of each leg, placing a significant burden on the user before the pressure treatment begins. Despite being a cumbersome device, the areas that can be treated with this device are limited to the user's legs, such as the thighs.

For this reason, in recent years, users have requested that a single device be used to perform stretching exercises (treatment 1) and pressure movements (treatment 2) on other treatment areas in addition to the left and right legs.

For example, there is a demand for a device that can perform Treatment 1, such as stretching exercises, on treatment areas such as the back, lower back, and buttocks, as well as Treatment 2, such as pressing movements, on the left and right legs. In other words, there is a demand for a device that can perform Treatment 1, such as stretching exercises, and Treatment 2, such as pressing movements, on various body parts, rather than being limited to treatment areas such as the legs as with conventional devices.

In view of the above problems, the present invention aims to provide an air stretching exercise device that includes a seat containing airbags that can be used to treat specific areas of the user's body. The airbags inflate to stretch areas such as the back and buttocks when the user is lying on their back, and also press against areas such as the thighs and calves when the user is seated on the seat with their upper body in an upright position.

To achieve the above objectives, the present invention employs the following technical measures.

The air stretching exercise device of the present invention comprises a pillow portion on which the user's head can be placed, a flexible seat portion connected to the front of the pillow portion, a first airbag disposed on the seat portion and pressing against the user's treatment area, and a drive portion for driving the first airbag , wherein the seat portion has a main body portion large enough for the user's treatment area to be placed on, a first extension portion disposed on the right outer side of the main body portion in the width direction, and a second extension portion disposed on the left outer side of the main body portion in the width direction.

Preferably, the first extension portion and the second extension portion are provided on the seat portion on the pillow portion side, and the third extension portion and the fourth extension portion are provided on the seat portion on the front side, opposite the pillow portion.

Preferably, the main body is provided with the first airbags, which are inflated by air supplied from the drive unit, at least on the front and rear sides.

Preferably, the right thigh placed on the rear airbag is wrapped around the first extension portion, and the left thigh placed on the rear airbag is wrapped around the second extension portion, so that the right thigh and the left thigh can be pressed against each other by the inflation of the rear airbag.

Preferably, the right calf placed on the front airbag is wrapped around the third extension portion, and the left calf placed on the front airbag is wrapped around the fourth extension portion, so that the right calf and the left calf can be pressed by the inflation of the front airbag.

Preferably, the main body is large enough for the user to lie on their back, and is configured so that, with the user's head placed on the pillow and lying face up on the main body, the first airbag disposed in the main body can inflate to perform stretching exercises on the treatment area from the user's back to their buttocks.

Preferably, the front airbag and the rear airbag are controlled to repeatedly inflate and deflate independently or in cooperation with each other.

Preferably, the first extension portion and the second extension portion are made of a belt member and are provided on the back side of the main body portion, and the belt member is flexible and configured so that it can be wrapped around the area to be treated by the user.

Preferably, the belt member is provided so that the first extension portion and the second extension portion protrude from the left and right sides of the main body portion, and is detachable from the main body portion.

An embodiment of the air stretching exercise device 1 according to the present invention will be described below with reference to the drawings. Note that the embodiment described below is one specific example of the present invention, and the configuration of the present invention is not limited to this specific example. Also, for ease of viewing, some components have been omitted and the drawings have been drawn using virtual lines.

When explaining this embodiment, the directions of the sheet-type air stretch exercise device 1 are defined as follows for ease of explanation:

As shown in Figures 1 to 5, in the longitudinal direction of the seat-type air stretch exercise device 1, the side facing the pillow section 2 is the "rear side," and the end side of the seat section 3 (main body section 5), opposite the pillow section 2, is the "front side." As shown in Figure 4, when a user U sits with their upper body B upright on the seat-type air stretch exercise device 1, the direction forward as seen from the user U is the "front side" of the air stretch exercise device 1.

3, when a user U lies on his/her back on the sheet-type air stretching exercise device 1, the direction in which the user U looks up (toward the ceiling) is defined as the "upper side" of the air stretching exercise device 1. The left and right directions of the air stretching exercise device 1 are as shown in the drawing.
[First embodiment]
1 to 4 show the configuration and usage of a first embodiment of an air stretching exercise device 1 according to the present invention.

As shown in Figures 1 to 4, the air stretching exercise device 1 of the present invention can be placed on a flat surface such as a floor F or a bed, and can perform stretching exercises (treatment 1) to stretch and loosen treatment areas such as the back K and buttocks D of a supine user U, from the shoulders through the back to the waist, and also perform pressing movements (treatment 2) to treatment areas such as the thighs T and calves C of the legs L (lower limbs L) with the upper body B in an upright position, all with the same device. Furthermore, the air stretching exercise device 1 of this embodiment can be made compact and portable by rolling up the sheet portion 3.

The air stretching exercise device 1 of this embodiment comprises a pillow section 2 on which the head H of a user U lying on their back can be placed, a flexible sheet section 3 connected to the front side of the pillow section 2, a first airbag 4 stored inside the sheet section 3 and inflating against the area to be treated of the user U to press and loosen it, and a drive section (not shown) that drives the first airbag 4. The first airbag 4 will be simply referred to as the airbag 4.

To give an example of the size of the air stretch exercise device 1 of this embodiment, the left-right length (width) of the seat portion 3 when unfolded is slightly larger than the shoulder width of the user U. In this embodiment, the seat portion 3 is provided with a first extension portion 6 (details will be described later) extending to the right, and a second extension portion 7 (details will be described later) extending to the left from the seat portion 3. Therefore, the air stretch exercise device 1 is long enough to reach the upper arms of the user U when both arms are spread out to the left and right.

Furthermore, when unfolded, the length in the front-to-back direction of this air stretching exercise device 1 roughly corresponds to the length from the user U's head H through the back K to the buttocks D. In other words, the air stretching exercise device 1 is large enough to support the upper body B.

As shown in Figures 1 to 4, the pillow section 2 is a hollow member that is elongated in the left-right direction. This pillow section 2 is a storage body that stores the drive unit that drives the airbag 4. The pillow section 2 is designed to accommodate the head H of a user U lying on their back on the seat section 3. The upper surface of the pillow section 2 may be rounded or flat, for example. The lower surface of the pillow section 2 is generally horizontal so that the pillow section 2 can be placed on a flat surface such as the floor F.

The entire outer periphery of the pillow part 2 (particularly the upper surface side that comes into contact with the head H) is covered with a cushioning material. In this embodiment, the pillow part 2 is a cylindrical member that is long in the left-right direction. Note that the shape of the pillow part 2 is not limited to the shape exemplified in this embodiment.

As shown in Figure 4, when the user U sits down on the seat 3, the pillow portion 2 comes into contact with the buttocks D and acts as a stopper member to prevent rearward movement.

The seat section 3 is connected to the front side of the pillow section 2. In other words, the pillow section 2 is connected to the rear side of the seat section 3. The seat section 3 can be laid on a floor surface F, etc., and is large enough for the user U to sit on. The seat section 3 is also large enough for the user U to lie on their back (with their upper body B resting on it). In other words, the seat section 3 is large enough to be spread out under the area to be treated of the user U (for example, the legs L or back K). The seat section 3 is also made of a flexible material, such as cloth.

The seat portion 3 has a main body portion 5 having a size large enough for the treatment part of the user U to rest on, a first extension portion 6 extending in a strip shape from the main body portion 5 to the right outer side in the width direction, and a second extension portion 7 extending in a strip shape from the main body portion 5 to the left outer side in the width direction. The first extension portion 6 and the second extension portion 7 are provided with second airbags 4 that are inflated by air supplied from a drive unit. The second airbag 4 will be simply referred to as the airbag 4.

The seat portion 3 also has a third extension portion 8 that extends in a strip-like shape from the center of the main body portion 5 toward the upper right side, and a fourth extension portion 9 that is arranged to form a pair with the third extension portion 8 and also extends in a strip-like shape toward the upper left side.

The main body 5 has an area large enough for the user U to lie on their back and sit down on. The main body 5 may be made, for example, by sewing together the edges of two identical pieces of fabric (upper fabric and lower fabric) to create a space inside, forming a bag-like shape.

A number of airbags 4 are provided inside the main body 5 (between the upper and lower fabrics). The airbags 4 press upward against the treatment areas of the back K, buttocks D, etc. of a user U who is lying supine with their upper body B placed on the main body 5, performing a stretching exercise to stretch and loosen the area. The airbags 4 also press against the treatment areas of the legs L (thighs T, calves C) of a user U who is sitting down on the main body 5 and raising their upper body B.

Although not shown, the sheet portion 3 (main body portion 5) may be configured so that it can be rolled up toward the pillow portion 2. For example, the main body portion 5, with the first extension portion 6 and the second extension portion 7 folded, may be rolled up and placed side by side next to the pillow portion 2, and the main body portion 5 may be secured with a hook-and-loop fastener or the like to prevent it from unraveling. Also, the main body portion 5, with the first extension portion 6 and the second extension portion 7 folded, may be wrapped around the outer periphery of the pillow portion 2 and secured in a roll, and the main body portion 5 may be secured with a hook-and-loop fastener or the like to prevent it from unraveling.

In this way, by rolling up the main body 5 and engaging it with a hook-and-loop fastener or similar, the air stretch exercise device 1 becomes compact and easy to carry. It also requires less storage space. Furthermore, by releasing the hook-and-loop fastener engagement, the main body 5 can be released from the pillow 2, allowing the air stretch exercise device 1 to be easily laid out on the floor F or the like.

As shown in Figures 1 to 4, airbags 4 that inflate with air supplied from a drive unit are provided at least on the front and rear sides inside the main body 5 (seat portion 3). In this embodiment, the airbags 4 consist of a rear airbag 4a and a front airbag 4b.

The rear airbags 4a include a first airbag 10 and a second airbag 11 (described in detail below). The front airbags 4b include a third airbag 14 and a fourth airbag 15 (described in detail below). In other words, in this embodiment, four airbags 4 are stored inside the main body 5.

These multiple airbags 4 are constructed by placing air-impermeable fabric bodies (such as vinyl) on top and bottom, with the edges joined together airtightly by welding or other means (welded structure).

More specifically, as shown in Figures 1 and 2, a first airbag 10 is disposed on the right rear side (pillow section 2 side) of the main body 5. A second airbag 11 is disposed on the left rear side (pillow section 2 side) of the main body 5. In other words, the first airbag 10 and the second airbag 11 are disposed adjacent to each other on the left and right sides of the rear side of the main body 5.

The first airbag 10 (right rear airbag 10) is deployed on the right rear side of the main body 5, and is positioned in a position corresponding to the right back K (shoulder, back, waist, etc.) of the user U lying supine on the main body 5. The first airbag 10 is also positioned in a position corresponding to the right thigh TR of the user U seated on the main body 5.

The first airbag 10 is a bag body that has a shape such as a rectangular or elliptical shape. In this embodiment, the first airbag 10 is a rectangular bag body that is long in the front-to-rear direction when viewed from above. The first airbag 10 is capable of storing pressurized air from a pump in the drive unit inside the pillow portion 2, and is freely inflatable and deflated to allow for large inflation.

A first air supply port 12 is provided on the rear side (pillow section 2 side) of the first airbag 10. The first air supply port 12 is connected to a pump inside the pillow section 2 via a first air supply hose. Air pressurized by the pump passes through the first air supply port 12 and is supplied into the first airbag 10. This pressurized air inflates the first airbag 10.

When the first airbag 10 inflates upward from the top surface of the main body 5, it lifts the treatment area on the right side of the back K (shoulders to lumbar region) of the user U lying face up on the main body 5, providing a stretching motion that stretches and loosens the area. Furthermore, when the first airbag 10 inflates upward, it lifts the treatment area on the right thigh TR of the user U seated on the main body 5, providing a pressing and loosening motion.

The second airbag 11 (left rear airbag 11) is the first airbag 10, flipped to the left (mirror image). In other words, the second airbag 11 and the first airbag 10 are bilaterally symmetrical. The configuration of the second airbag 11 is substantially the same as that of the first airbag 10, so a detailed description will be omitted. However, only a general description of the second airbag 11 will be given.

A second air supply port 13 is provided on the rear side (pillow section 2 side) of the second airbag 11. Air pressurized by a pump inside the pillow section 2 passes through the second air supply port 13 and is supplied into the second airbag 11, causing the second airbag 11 to inflate.

When this second airbag 11 inflates upward from the top surface of the main body 5, it lifts the treatment area on the left side of the back K (shoulder to lumbar region) of the user U lying face up on the main body 5, providing a stretching motion that stretches and loosens the area. Furthermore, when the second airbag 11 inflates upward, it lifts the treatment area on the left thigh TL of the user U seated on the main body 5, providing a pressing and loosening motion.

Now, a third airbag 14 is disposed on the right front side of the main body 5 (in front of the first airbag 10). Furthermore, a fourth airbag 15 is disposed on the left front side of the main body 5 (in front of the second airbag 11). In other words, the third airbag 14 and the fourth airbag 15 are disposed adjacent to each other as a pair on the left and right sides at the rear of the main body 5. Furthermore, the first airbag 10 and the third airbag 14 are provided in a front-to-back row on the right side of the main body 5.

The third airbag 14 (right front airbag 14) is arranged on the right front side of the main body 5, and is disposed in a position corresponding to the right buttocks D of the user U lying on his back on the main body 5. The third airbag 14 also covers the right calf CR of the user U seated on the main body 5.
They are also placed in positions corresponding to the above.

The third airbag 14 is a bag body that has a shape such as a rectangular or elliptical shape. In this embodiment, the third airbag 14 is a bag body that is elliptical and long in the left-right direction when viewed from above. The third airbag 14 is capable of storing pressurized air from the pump of the drive unit inside the pillow portion 2, and is freely inflatable and deflates to a large extent.

A right air passage 16 is provided behind the third airbag 14, through which air supplied from the pump passes. This right air passage 16 is arranged to pass through the right outer side of the first airbag 10. In plan view, the right air passage 16 is a cylindrical bag body that is long in the front-to-rear direction. In other words, the right air passage 16 is formed so as to be in communication with the third airbag 14.

A third air supply port 17 is provided at the rear side (pillow section 2 side) of the right air passage 16. The third air supply port 17 is connected to a pump inside the pillow section 2 via a third air supply hose. Air pressurized by the pump enters through the third air supply port 17, passes through the right air passage 16, and is supplied to the third airbag 14. This pressurized air inflates the third airbag 14.

By inflating upward from the top surface of the main body 5, the third airbag 14 lifts the treatment area, such as the right buttocks D, of the user U lying face-up on the main body 5, providing a stretching motion that stretches and loosens the area. Furthermore, by inflating upward, the third airbag 14 lifts the treatment area, such as the right calf CR, of the user U seated on the main body 5, providing a pressing and loosening motion.

The fourth airbag 15 (left front airbag 15) is the third airbag 14, inverted (mirror-imaged) to the left. In other words, the fourth airbag 15 and the third airbag 14 are bilaterally symmetrical. The second airbag 11 and the fourth airbag 15 are arranged in a front-to-rear row on the left side of the main body 5. The configuration of the fourth airbag 15 is substantially the same as that of the third airbag 14, so a detailed description will be omitted. However, only a general description of the fourth airbag 15 will be given.

A left air passage 18 is provided behind the fourth airbag 15, through which air supplied from the pump passes. This left air passage 18 is designed to pass through the left outside of the second airbag 11.

A fourth air supply port 19 is provided at the rear side (pillow section 2 side) of the left air passage 18. Air pressurized by a pump inside the pillow section 2 enters through the fourth air supply port 19, passes through the left air passage 18, and is supplied to the fourth airbag 15, causing the fourth airbag 15 to inflate.

By inflating upward from the top surface of the main body 5, the fourth airbag 15 lifts the treatment area, such as the left buttocks D, of the user U lying face-up on the main body 5, providing a stretching motion that stretches and loosens the area. Furthermore, by inflating upward, the fourth airbag 15 lifts the treatment area, such as the left calf CL, of the user U seated on the main body 5, providing a pressing and loosening motion.

The first to fourth airbags 10 to 15 (rear airbag 4a and front airbag 4b) are controlled to repeatedly inflate and deflate independently or in cooperation with each other. This control allows for a variety of stretching exercises, pressing movements (massage movements), and more.

The shapes of the first airbag 10 to the fourth airbag 15 are not particularly limited, as long as they can provide stretching exercises for treatment areas such as the back K and buttocks D of a user U (upper body B) lying supine on the main body 5 (seat 3), and can also provide a pressing action for treatment areas such as the thighs T and calves C of a user U seated on the main body 5.

As shown in Figures 1 to 4, the first extension portion 6 is a member that extends in a band shape (e.g., like extending the right arm) from the right edge of the main body portion 5 outward in the width direction. In this embodiment, the first extension portion 6 is provided on the right edge, rear side of the main body portion 5 (seat portion 3) on the pillow portion 2 side. The first extension portion 6 is provided, for example, at a location corresponding to the base of the right thigh TR when the user U is seated on the main body portion 5, or at a location corresponding to the right shoulder of the upper body B when the user U is lying supine on the main body portion 5.

The first extension portion 6 is flexible. Therefore, the first extension portion 6 can be folded and placed on top of the main body portion 5. The length of the first extension portion 6 is such that it can be wrapped around the right thigh region TR (first treatment area), which is one of the treatment areas of the user U placed on the main body portion 5. The first extension portion 6 may also be made of the same fabric material as the main body portion 5.

In other words, the first extension portion 6 is a member that can be laid on the floor F or wrapped around the right thigh TR by pulling it from the right outer side toward the inside. When the user U lies on their back on the main body portion 5, the user U's right arm can be placed on it. Like the main body portion 5, the first extension portion 6 is formed into a bag shape by sewing together two pieces of fabric material of the same shape.

Furthermore, in this embodiment, the airbag 4 includes a fifth airbag 20 and a sixth airbag 22.

A fifth airbag 20 (airbag 4) that inflates with air supplied from a drive unit is provided inside the first extension portion 6. When the first extension portion 6 is wrapped around the right thigh region TR, the fifth airbag 20 is deployed in a position facing the first airbag 10.

The fifth airbag 20 is connected to a pump inside the pillow section 2. Air pressurized by the pump inside the pillow section 2 is supplied into the fifth airbag 20, causing the fifth airbag 20 to inflate.

This fifth airbag 20 inflates upward from the top surface of the first extension portion 6, lifting the treatment area of the right arm placed on the first extension portion 6 and providing a stretching motion to stretch and loosen it. Furthermore, when the first extension portion 6 is wrapped around the right thigh TR of a user U seated on the main body 5, the fifth airbag 20 inflates downward, providing a pressing action against the treatment area of the right thigh TR.

The shapes of the first extension portion 6 and the fifth airbag 20 are not particularly limited, as long as they are shaped to wrap around the treatment area of the thighs T of a user U seated on the main body portion 5 (seat portion 3).

As shown in Figures 1 to 4, the second extension portion 7 has a configuration in which the first extension portion 6 is inverted to the left (mirror inversion). In other words, the second extension portion 7 and the first extension portion 6 are bilaterally symmetrical. The configuration of the second extension portion 7 is substantially the same as that of the first extension portion 6.

The second extension portion 7 is a member that extends in a band shape (e.g., like an outstretched left arm) from the left edge of the main body portion 5 outward in the width direction. In this embodiment, the second extension portion 7 is provided on the left edge, behind the main body portion 5 (seat portion 3) on the pillow portion side 2. The second extension portion 7 is provided, for example, at a location corresponding to the base of the left thigh TL when the user U is seated on the main body portion 5, or at a location corresponding to the left shoulder of the upper body B when the user U is lying supine on the main body portion 5.

The second extension portion 7 is flexible. Therefore, the second extension portion 7 can be folded and placed on top of the main body portion 5. The length of the second extension portion 7 is such that it can be wrapped around the left thigh TL (second treatment area), which is one of the treatment areas of the user U placed on the main body portion 5. The second extension portion 7 may also be made of the same fabric material as the main body portion 5.

In other words, the second extension portion 7 is a member that can be laid on the floor F or wrapped around the left thigh TL by pulling it from the outside to the inside of the left side. When the user U lies on their back on the main body portion 5, the user U's left arm can be placed on it. Like the first extension portion 6, the second extension portion 7 is formed into a bag shape by sewing together two pieces of fabric material of the same shape.

The sixth airbag 22 (airbag 4) is provided inside the second extension portion 7 and is inflated by air supplied from the drive unit. The sixth airbag 22 has a configuration in which the fifth airbag 20 is inverted to the left (mirror image). In other words, the sixth airbag 22 and the fifth airbag 20 are bilaterally symmetrical. The configuration of the sixth airbag 22 is substantially the same as that of the fifth airbag 20.

When the second extension portion 7 is wrapped around the left thigh region TL, the sixth airbag 22 is deployed in a position facing the second airbag 11. The sixth airbag 22 is connected to a pump in the pillow portion 2. Air pressurized by the pump in the pillow portion 2 is supplied into the sixth airbag 22, causing the sixth airbag 22 to inflate.

The fifth airbag 20 and the sixth airbag 22 are configured to be able to inflate and deflate independently and alternately. Furthermore, the fifth airbag 20 and the sixth airbag 22 also inflate and deflate independently and alternately with respect to the first airbag 10 through the fourth airbag 22.

This sixth airbag 22 inflates upward from the top surface of the second extension portion 7, lifting the treatment area of the left arm placed on the second extension portion 7 and providing a stretching motion to stretch and loosen it. Furthermore, when the second extension portion 7 is wrapped around the left thigh TL of the user U seated on the main body 5, the sixth airbag 22 inflates downward, providing a pressing action against the treatment area of the left thigh TL.

The shapes of the second extension portion 7 and the sixth airbag 22 are not particularly limited, as long as they are shaped to wrap around the treatment area of the thighs T of a user U seated on the main body portion 5 (seat portion 3).

The first airbag 10 to the fourth airbag 15 of the main body 5, the fifth airbag 20 of the first extension 6, and the sixth airbag 22 of the second extension 7 (airbag 4) are constructed with a welded structure. The right air passage 16, which supplies air from the pump to the third airbag 14, and the left air passage 18, which supplies air from the pump to the fourth airbag 15, are also constructed with a welded structure. In other words, each of the airbags 10, 11, 14, 15, 20, and 22 (airbag 4) is also flexible.

As a result, the first extension portion 6 and the second extension portion 7 of the seat portion 3 can be stacked on the main body portion 5, and the main body portion 5 can be easily wound up into a roll. At this time, the airbags 10, 11, 14, 15, 20, and 22 (airbags 4) do not bend or twist, and the right air passage 16, left air passage 18, etc. are not damaged.

Now, an engaging member 21 is provided to engage the first extension portion 6 and the second extension portion 7. In this embodiment, the engaging member 21 is a buckle member 21. One side of the buckle member 21 used to engage with the second extension portion 7 is provided at the tip side of the first extension portion 6. Furthermore, the other side of the buckle member 21 used to engage with the first extension portion 6 is provided at the tip side of the second extension portion 7.

The first extension portion 6 is wrapped around the outer periphery of the right thigh TR, and the second extension portion 7 is wrapped around the outer periphery of the left thigh TL. One of the buckle members 21 provided at the tip of the first extension portion 6 is engaged with the other buckle member 21 provided at the tip of the second extension portion 7 to secure the buckle members 21. By adjusting the length of the belt threaded through the buckle members 21, the left and right thighs T placed on the main body 5 are appropriately tightened, securing the right thigh TR and left thigh TL. This allows the right thigh TR and left thigh TL (legs L) to be stable on the main body 5.

The engaging member 21 may be a hook-and-loop fastener. In this case, the first extension portion 6 and the second extension portion 7 are engaged by being stuck together.

As shown in Figures 1 to 4, the third extension portion 8 is provided on the front side of the seat portion 3, opposite the pillow portion 2. In other words, the third extension portion 8 is provided on the front end side of the main body portion 5. This third extension portion 8 is a strip-shaped member whose base end protrudes upward from the center of the main body portion 5 and whose tip extends diagonally to the right.

The third extension portion 8 is flexible. Therefore, the third extension portion 8 is arranged so as to overlap the main body portion 5 from the base end toward the tip end. In other words, the third extension portion 8 is arranged so as to be layered on the main body portion 5 (third airbag 14) and can be lifted up. The third extension portion 8 may also be formed from the same fabric material as the main body portion 5.

The third extension portion 8 in this embodiment is provided in the right front region on the main body portion 5. For example, the third extension portion 8 is provided in a position corresponding to the right calf CR when the user U is in a seated position, or in a position corresponding to the right buttock D when the user U is in a supine position. The length of the third extension portion 8 is
The length is such that the right calf CR (third treatment area), which is one of the treatment areas of the user U, can be wrapped from the inside to the right outside.

The third extension portion 8 may be formed into a bag shape by sewing together two pieces of fabric of the same shape, just like the first extension portion 6. In this case, it is preferable to provide an airbag 4 inside the third extension portion 8 that inflates with air supplied from the drive unit.

The tip of the third extension 8 is provided with an engaging member 23 that engages with the front right edge of the main body 5. In this embodiment, the engaging member 23 is a hook-and-loop fastener 23, and one side of the engaging member 23 is provided. The other side of the hook-and-loop fastener 23 is provided on the back surface of the front right edge of the main body 5.

The third extension portion 8 is wrapped around the outer circumference of the right calf CR, and the front right edge of the main body portion 5 is raised and attached to the main body portion 5, and the third extension portion 8 is engaged with the hook-and-loop fastener 23. The right calf CR placed on the main body portion 5 is then appropriately tightened to secure the right calf CR. This stabilizes the right calf CR (leg L) on the main body portion 5.

As shown in Figures 1 to 4, the fourth extension portion 9 is provided on the front side of the seat portion 3, opposite the pillow portion 2. In other words, the fourth extension portion 9 is provided on the front end side of the main body portion 5. The fourth extension portion 9 is arranged adjacent to the third extension portion 8.

The fourth extension portion 9 is a strip-shaped member whose base end protrudes upward from the center of the main body portion 5 and whose tip extends diagonally to the left. In other words, the fourth extension portion 9 is arranged to form a left-right pair with the third extension portion 8.

The fourth extension portion 9 is flexible. Therefore, the fourth extension portion 9 is arranged so as to overlap the main body portion 5 from the base end toward the tip end. In other words, the fourth extension portion 9 is arranged so as to be layered on the main body portion 5 (fourth airbag 15) and can be lifted. The fourth extension portion 9 may also be made of the same fabric material as the main body portion 5.

In this embodiment, the fourth extension portion 9 is provided in the left front region on the main body portion 5. The fourth extension portion 9 is provided, for example, in a location corresponding to the left calf CL when the user U is seated, or in a location corresponding to the left buttocks D when the user U is lying on their back. The length of the fourth extension portion 9 is such that it can be wrapped around the left calf CL (fourth treatment portion), which is one of the treatment portions of the user U, from the inside to the outside on the left.

The fourth extension portion 9 may be formed into a bag shape by sewing together two pieces of fabric of the same shape, just like the second extension portion 7. In this case, it is preferable to provide an airbag 4 inside the fourth extension portion 9 that inflates with air supplied from a drive unit.

Furthermore, the shapes of the third extension portion 8 and the fourth extension portion 9 are not particularly limited, as long as they are shaped to wrap around the treatment area of the calf C of the user U seated on the main body portion 5 (seat portion 3).

The tip of the fourth extension 9 is provided with an engaging member 24 used to engage with the front left edge of the main body 5. In this embodiment, the engaging member 24 is a hook-and-loop fastener 24, and one side of the engaging member 24 is provided. The other side of the hook-and-loop fastener 24 is provided on the back surface of the front left edge of the main body 5.

The fourth extension portion 9 is wrapped around the outer circumference of the left calf CL, and the front left edge of the main body portion 5 is raised and attached to the main body portion 5, and the fourth extension portion 9 is engaged with the hook-and-loop fastener 24. The left calf CL placed on the main body portion 5 is then appropriately tightened to secure the left calf CL. This stabilizes the left calf CL (leg L) on the main body portion 5.

Here, we will briefly explain the drive unit that inflates the airbag 4.

The drive unit is stored inside the pillow section 2. The drive unit includes a pump (compressor) that supplies pressurized air to inflate each airbag 4 (first airbag 10 to sixth airbag 22), an air supply hose connected to the pump that directs air to each airbag 4, a solenoid valve that controls the amount of air supplied to each airbag 4, and a control unit that controls this solenoid valve.

The pump sends pressurized air to the solenoid valve, and after passing through the solenoid valve, the pressurized air is supplied to each airbag 4 via an air supply hose or the like. The solenoid valve switches between introducing air into each airbag 4 and discharging air from each airbag 4. The pressurized air from the pump passes through the solenoid valve and the air supply hose or the like, and is supplied to each airbag 4, causing it to inflate.

This solenoid valve is controlled by the control unit, which sends air from the pump to each designated airbag 4. The control unit is programmed with programs that perform multiple stretching exercises and/or pressure movements (massage movements), and controls the inflation and deflation of each airbag 4 for each program.

This allows the user U to select the desired stretching exercise and/or pressure action for the treatment area, such as the back K or buttocks D, or the treatment area, such as the thighs T or calves C. The drive unit may be provided with a structure for heating air. That is, it is preferable to heat pressurized air from the pump to provide warm air to the airbag 4, so that warm stretching exercise (pressure massage) can also be performed on the seat unit 3.
[Usage]
Next, the manner of use of the first embodiment of the air stretching exercise device 1 of the present invention will be described with reference to the drawings.
[Treatment 1 (stretching exercise)]
FIG. 3 shows usage mode 1 "Treatment 1" of the air stretching exercise device 1 of this embodiment.

As shown in Figure 3, the air stretching exercise device 1 of this embodiment is capable of performing stretching exercises to stretch and loosen treatment areas such as the user U's back K and buttocks D.

More specifically, the air stretching exercise device 1 allows the user U to lie face up with their head H placed on the pillow section 2 and their upper body B placed on the main body section 5, and stretch the treatment area from their back K to their buttocks D by inflating and deflating (expanding and contracting) the airbags 4 built into the main body section 5.

Here, we will explain the inflation and deflation of the first airbag 10 to the fourth airbag 15 in "Treatment 1." In this embodiment, the first airbag 10 to the fourth airbag 15 are configured to be able to inflate and deflate independently and alternately.
<Front and rear airbags inflate alternately>
For example, the first airbag 10 and the second airbag 11 arranged on the rear side of the main body 5 constituting the seat 3 are inflated. Alternate inflation and deflation control may be performed so that the third airbag 14 and the fourth airbag 15 arranged on the front side of the main body 5 begin to inflate at the same time as the airbags 10 and 11 are deflated.

Specifically, when the first airbag 10 inflates, the right side of the back K of the user U lying face up on the main body 5 is lifted, and when the second airbag 11 inflates, the left side of the back K of the user U is lifted, thereby performing a stretching exercise on the back K.

Next, airbags 10 and 11 deflate, and third airbag 14 inflates, lifting the right buttocks D of user U, while fourth airbag 15 inflates, lifting the left buttocks D of user U, thereby performing a stretching exercise for buttocks D.

That is, the first airbag 10 and the second airbag 11 (rear airbag 4a) may be used to stretch the back K, and the third airbag 14 and the fourth airbag 15 (front airbag 4b) may be used to stretch the buttocks D.
<Left and right airbags inflate alternately>
Also, the first airbag 10 and the third airbag 14 disposed on the right side of the main body 5 constituting the seat 3 are inflated. Alternate inflation and deflation control may be performed so that the second airbag 11 and the fourth airbag 15 disposed on the left side of the main body 5 begin to inflate at the same time as the airbags 10 and 14 are deflated.

Specifically, when the first airbag 10 inflates, the right side of the back K of the user U lying on his back on the main body 5 is lifted, and when the third airbag 14 inflates, the right side of the buttocks D of the user U is lifted, thereby performing a stretching exercise for the right side of the back K and buttocks D.

Next, the airbags 10 and 14 deflate, and the second airbag 11 inflates, lifting the left side of the user U's back K. The fourth airbag 15 inflates, lifting the left side of the user U's buttocks D, thereby performing a stretching exercise for the left side of the back K and buttocks D.

That is, the first airbag 10 and the third airbag 14 on the right side may be used to stretch the back K and buttocks D on the right side, and the second airbag 11 and the fourth airbag 15 on the left side may be used to stretch the back K and buttocks D on the left side.
<Airbags inflate alternately in the cross direction>
Also, the first airbag 10 on the right rear side and the fourth airbag 15 on the left front side, which are arranged in a cross direction in the main body 5 constituting the seat unit 3, are inflated. Alternate inflation and deflation control may be performed so that the second airbag 11 on the left rear side and the third airbag 14 on the right front side, which are arranged in the opposite cross direction, begin to inflate at the same time as the airbags 10, 15 are deflated.

Specifically, when the first airbag 10 inflates, the right side of the back K of the user U lying face up on the main body 5 is lifted, and when the fourth airbag 15 inflates, the left side of the buttocks D of the user U is lifted, thereby performing a stretching exercise for the right side of the back K and the left side of the buttocks D.

Next, the airbags 10 and 15 deflate, and the second airbag 11 inflates, lifting the left side of the user U's back K. The third airbag 14 inflates, lifting the right side of the user U's buttocks D, thereby performing a stretching exercise for the left side of the back K and the right side of the buttocks D.

In other words, the first airbag 10 and fourth airbag 15, which are arranged in a cross direction, may be used to stretch the right side of the back K and the left side of the buttocks D, and the second airbag 11 and third airbag 14 may be used to stretch the left side of the back K and the right side of the buttocks D.

In this way, the desired stretching effect can be achieved by alternately inflating and deflating the predetermined airbags 10, 11, 14, and 15. The timing of inflation and deflation of each airbag 10, 11, 14, and 15 can also be individually controlled to be delayed or advanced.
[Treatment 2 (pressure operation)]
FIG. 4 shows the second usage mode "Treatment 2" of the air stretching exercise device 1 of this embodiment.

As shown in Figure 4, the air stretching exercise device 1 of this embodiment can apply pressure to treatment areas of the user U's legs L, such as the thighs T and calves C.

In more detail, the air stretching exercise device 1 wraps the right thigh TR, which is placed on the first airbag 10 (rear airbag 4a), with the first extension portion 6 equipped with the fifth airbag 20, and wraps the left thigh TL, which is placed on the second airbag 11 (rear airbag 4a), with the second extension portion 7 equipped with the sixth airbag 22.

The inflation and deflation of the first airbag 10 (rear airbag 4a) and the fifth airbag 20 enable them to press against the right thigh region TR, and the inflation and deflation of the second airbag 11 (rear airbag 4a) and the sixth airbag 22 enable them to press against the left thigh region TL.

In addition, the air stretch exercise device 1 wraps the third extension portion 8 around the right calf CR placed on the third airbag 14 (front airbag 4b), and wraps the fourth extension portion 9 around the left calf CL placed on the fifth airbag 15 (front airbag 4b).

When the third airbag 14 (front airbag 4b) expands and contracts, it can press against the right calf CR, and when the fifth airbag 15 (front airbag 4b) expands and contracts, it can press against the left calf CL.

First, the third extension portion 8 is wrapped around the outer periphery of the right calf CR, the front right edge of the main body 5 is lifted, and the third extension portion 8 is engaged with the hook-and-loop fastener 23. Next, the fourth extension portion 9 is wrapped around the outer periphery of the left calf CL, the front left edge of the main body 5 is lifted, and the fourth extension portion 9 is engaged with the hook-and-loop fastener 24. This fixes the right calf CR and left calf CL (leg L) and stabilizes them on the main body 5. The third airbag 14 is in contact with the right calf CR, and the fourth airbag 15 is in contact with the left calf CL.

The first extension portion 6 is wrapped around the outer periphery of the right thigh portion TR, and the second extension portion 7 is wrapped around the outer periphery of the left thigh portion TL, and the first extension portion 6 and the second extension portion 7 are fastened together with the buckle member 21. This secures the right thigh portion TR and the left thigh portion TL (leg portion L) and keeps them stable on the main body portion 5.

The first airbag 10 and fifth airbag 20 are in contact with the right thigh region TR, and the second airbag 11 and sixth airbag 22 are in contact with the left thigh region TL. In other words, the fifth airbag 20 is deployed in a position facing the first airbag 10 across the right thigh region TR. The sixth airbag 22 is deployed in a position facing the second airbag 11 across the left thigh region TL.

Here, we will explain the inflation and deflation of the first airbag 10 to the sixth airbag 22 in "Treatment 2." In this embodiment, the first airbag 10 to the sixth airbag 22 are configured to be able to inflate and deflate independently and alternately.
<Front and rear airbags inflate alternately>
For example, the first airbag 10 and the fifth airbag 20, and the second airbag 11 and the sixth airbag 22, which are arranged on the rear side (the pillow portion 2 side) of the main body 5 constituting the seat portion 3, are inflated. Alternate inflation and deflation control may be performed so that the third airbag 14 and the fourth airbag 15, which are arranged on the front side of the main body 5, begin to inflate at the same time as the airbags 10, 11, 20, and 22 are deflated.

Specifically, the first airbag 10 and the fifth airbag 20 inflate to press against the right thigh TR of the user U who is seated on the main body 5 with the upper body B in an upright position, and the second airbag 11 and the sixth airbag 22 inflate to press against the left thigh TL of the user U, thereby performing a pressing action on the thigh T.

Next, the airbags 10, 11, 20, and 22 deflate, and the third airbag 14 inflates, compressing the right calf CR of the user U. The fourth airbag 15 inflates, compressing the left calf CL of the user U, thereby performing a compressive action on the calf C.

In other words, the first airbag 10 and the fifth airbag 20, and the second airbag 11 and the sixth airbag 22 (rear airbag 4a) may be used to provide a pressure massage to the thighs T, and the third airbag 14 and the fourth airbag 15 (front airbag 4b) may be used to provide a pressure massage to the calves C.
<Left and right airbags inflate alternately>
Also, the first airbag 10, the fifth airbag 20, and the third airbag 14, which are arranged on the right side of the main body 5 constituting the seat 3, are inflated. Alternate inflation and deflation control may be performed so that the second airbag 11, the sixth airbag 22, and the fourth airbag 15, which are arranged on the left side of the main body 5, begin to inflate at the same time as the airbags 10, 14, and 20 are deflated.

Specifically, when the first airbag 10 and the fifth airbag 20 inflate, they press against the right thigh TR of the user U who is seated on the main body 5 with their upper body B raised, and when the third airbag 14 inflates, they press against the right calf CR of the user U, thereby applying a pressing action to the right thigh TR and right calf CR.

Next, airbags 10, 14, and 20 deflate, and second airbag 11 and sixth airbag 22 inflate, compressing the left thigh TL of user U. At the same time, fourth airbag 15 inflates, compressing the left calf CL of user U, thereby applying a compressive action to the left thigh TL and left calf CL.

In other words, the first airbag 10, the fifth airbag 20, and the third airbag 14 on the right side may be used to provide a pressure massage to the right thigh TR and the right calf CR, and the second airbag 11, the sixth airbag 22, and the fourth airbag 15 on the left side may be used to provide a pressure massage to the left thigh TL and the left calf CL.
<Airbags inflate alternately in the cross direction>
Also, the first airbag 10 and the fifth airbag 20 on the right rear side and the fourth airbag 15 on the left front side, which are arranged in a cross direction in the main body 5 that constitutes the seat unit 3, are inflated. Alternate inflation and deflation control may be performed so that the second airbag 11 and the sixth airbag 22 on the left rear side and the third airbag 14 on the right front side, which are arranged in the opposite cross direction, begin to inflate at the same time as the airbags 10, 15, 20 are deflated.

Specifically, when the first airbag 10 and the fifth airbag 20 inflate, they press against the right thigh TR of the user U who is seated on the main body 5 with their upper body B raised, and when the fourth airbag 15 inflates, they press against the left calf CL of the user U, thereby applying a pressing action to the right thigh TR and left calf CL.

Next, airbags 10, 15, and 20 deflate, and second airbag 11 and sixth airbag 22 inflate, compressing the left thigh TL of user U. At the same time, third airbag 14 inflates, compressing the right calf CR of user U, thereby applying a compressive action to the left thigh TL and right calf CR.

In other words, the first airbag 10, fifth airbag 20, and fourth airbag 15, which are arranged in a cross direction, may be used to provide a pressure massage to the right thigh region TR and left calf CL, and the second airbag 11, sixth airbag 22, and third airbag 14 may be used to provide a pressure massage to the left thigh region TL and right calf CR.

In this way, the desired pressing effect (massage effect) can be obtained by alternately inflating and deflating the predetermined airbags 10, 11, 14, 15, 20, and 22. The timing of inflation and deflation of each airbag 10, 11, 14, 15, 20, and 22 can also be individually controlled to be delayed or advanced.
Second Embodiment
Fig. 5A is a schematic diagram showing the front side of a second embodiment of the air stretching exercise device 1 according to the present invention, and Fig. 5B is a schematic diagram showing the back side of the second embodiment of the air stretching exercise device 1 according to the present invention.

In this embodiment, the configuration of the pillow portion 2, the main body portion 5 of the seat portion 3, and the airbags 4 (the first airbag 10 and second airbag 11 of the rear airbag 4a, and the third airbag 14 and fourth airbag 15 of the front airbag 4b) built into the main body portion 5 are substantially the same as those in the first embodiment described above, so a detailed description of the configuration will be omitted.

As shown in Figures 5A and 5B, the first extension portion 6 in this embodiment is a band-shaped member extending from the front end side of the main body portion 5. In other words, the first extension portion 6 is a belt-shaped member extending from the right edge of the front end side of the main body portion 5 to the outer right in the width direction.

In this embodiment, the first extension portion 6 is provided at the front end and right edge of the main body portion 5. The first extension portion 6 is provided, for example, at a location corresponding to the right calf CR when the user U is seated on the main body portion 5, or at a location corresponding to the right buttock D or lower back when the user U is lying on their back.

The first extension portion 6 is flexible. Therefore, the first extension portion 6 can be folded toward the front end of the main body portion 5 and stacked on top of it. The length of the first extension portion 6 is such that it can be wrapped around the right calf CR placed on top of the main body portion 5. The first extension portion 6 may be made of the same fabric material as the main body portion 5. Note that in this embodiment, the fifth airbag 20 (airbag 4) is not built in.

In this embodiment, the second extension portion 7 is a band-shaped member extending from the front end side of the main body portion 5. In other words, the second extension portion 7 is a belt-shaped member extending from the left edge of the front end side of the main body portion 5 to the left outer side in the width direction.

In this embodiment, the second extension portion 7 is provided on the front end and left edge of the main body portion 5. The second extension portion 7 is provided, for example, in a location corresponding to the left calf CL when the user U is seated, or in a location corresponding to the left buttocks D or lower back when the user U is lying on their back.

The second extension portion 7 is flexible. Therefore, the second extension portion 7 can be folded toward the front end of the main body portion 5 and overlapped. The length of the second extension portion 7 is such that it can be wrapped around the left calf CL placed on the main body portion 5. The second extension portion 7 is made of the same fabric material as the main body portion 5. In this embodiment, the sixth airbag 22 (airbag 4) is not built in. In addition, in this embodiment, the third extension portion 8 and the fourth extension portion 9 are not provided.

As shown in Figure 5A, in this embodiment, a buckle member 21 is used as the engagement member 21. In this embodiment, one side of the buckle member 21 is provided at the tip side of the first extension portion 6. Furthermore, the other side of the buckle member 21 is provided at the tip side of the second extension portion 7.

The first extension portion 6 is wrapped around the outer periphery of the right calf CR, and the second extension portion 7 is wrapped around the outer periphery of the left calf CL. One end of the buckle members 21 at the tip of each extension portion 6, 7 is engaged with the other end to secure the buckle members 21. This allows the right calf CR and left calf CL (leg L) to be stable on the main body portion 5.

As shown in FIG. 5B, in this embodiment, the first extension portion 6 and the second extension portion 7 are a single belt member 25 provided separately from the main body portion 5. The belt member 25 is provided on the back side of the main body portion 5. The belt member 25 is provided so that the first extension portion 6 and the second extension portion 7 protrude from the left and right sides of the main body portion 5, and is detachable from the main body portion 5.

The belt member 25 is a long, horizontally elongated band member that is narrowed in the middle of its length. In other words, the belt member 25 is constricted in the middle of its length. The belt member 25 is flexible. This allows the belt member 25 to be folded or wrapped around the treatment area or body of the user U.

A belt fastening member 26 is provided on the back surface of the main body 5, which aligns and fastens the belt member 25. In this embodiment, the belt fastening member 26 is formed from a rectangular cloth material that is long in the front-to-rear direction. This belt fastening member 26 is sewn to the front side of the back surface of the main body 5, in the center in the left-to-right direction. The belt fastening member 26 has belt holes 27 through which the belt member 25 can be passed in the left-to-right direction. Multiple belt holes 27 are provided on the front and back, allowing the position of the belt member 25 to be adjusted in the front-to-rear direction.

More specifically, the belt fastening member 26 is attached to the underside of the main body 5 by stitching its front and rear edges in the left-right (width) direction, and its midway portion in the longitudinal direction is also attached to the underside of the main body 5 by stitching in the left-right direction. In other words, the belt fastening member 26 is attached to the underside of the main body 5 by being sewn at four equally spaced locations in the front-to-rear direction. A space 27 penetrating in the left-to-right direction is formed between these sewn portions. This space 27 is the belt hole 27 mentioned above. The size of this belt hole 27 is smaller than the wide portion of the belt member 25 and larger than the narrowed portion (midway in the longitudinal direction). Because the wide portion of the belt member 25 is larger than the belt hole 27, the belt member 25 will not fall off the belt fastening member 26 when attached to the main body 5.

A plurality of belt holes 27 are provided in the belt fastening member 26, spaced at equal intervals in the front-to-rear direction. In this embodiment, the belt fastening member 26 is sewn to the back surface of the main body 5 so as to create three belt holes 27a-27c in the front-to-rear direction. The front-to-rear position of the belt member 25 on the main body 5 can be adjusted by passing the belt member 25 through one of these belt holes 27a-27c. This makes it possible to change the wrapping positions of the first extension portion 6 and the second extension portion 7 relative to the treatment area. Note that the number of belt holes 27 is not limited to the example shown, and may be two or four, and is not limited to any particular number.

As shown in FIG. 5B, for example, the wide portion of the belt member 25 (first extension portion 6 or second extension portion 7) is bent so that it is smaller than the belt hole 27b, and the belt member 25 is passed through the belt hole 27b. When the belt member 25 reaches the narrowed portion (midway in the longitudinal direction), the first extension portion 6 and the second extension portion 7 protrude from the left and right sides of the main body portion 5, and the belt member 25 is then unfolded. Because the wide portion of the belt member 25 is larger than the belt hole 27b, it will not fall off the main body portion 5 (belt fastening member 26). Note that the belt member 25 may be passed through either the belt hole 27a or the belt hole 27c.

In this way, the belt member 25 is positioned in the front-to-rear direction and attached to the main body 5. Then, the first extension portion 6 and the second extension portion 7 are wound around the treatment area of the user U placed on the main body 5, and the buckle member 21 is fixed.

The belt member 25 can be removed from the main body 5 by removing it from the belt hole 27b (belt fastening member 26). This can be done when changing the position of the belt member 25 or storing the air stretch exercise device 1.

Figure 5C shows a schematic diagram of a modified example of the second embodiment of the air stretching exercise device 1 according to the present invention.

As shown in Figure 5C, this modification uses a hook-and-loop fastener 21 as the engaging member 21. The other configuration of this modification is substantially the same as that of the second embodiment described above.

In this modified example, one side of the hook-and-loop fastener 21 is provided at the tip side of the first extension portion 6. Furthermore, the other side of the hook-and-loop fastener 21 is provided at the tip side of the second extension portion 7.

The first extension portion 6 is wrapped around the outer periphery of the right calf CR, and the second extension portion 7 is wrapped around the outer periphery of the left calf CL. One end of the hook-and-loop fasteners 21 at the tip of each extension portion 6, 7 is engaged with the other end to secure the hook-and-loop fasteners 21. This allows the right calf CR and left calf CL to be stable on the main body portion 5.

An engaging member 28 is provided in the center of the front edge of the main body portion 5 (seat portion 3). In this modified example, a hook-and-loop fastener 21 is used as the engaging member 28. The main body portion 5 is wrapped around the outer periphery of the pillow portion 2, and the hook-and-loop fastener 21 engages the main body portion 5 to prevent it from unraveling. In other words, the sheet portion 3 (main body portion 5) is configured to be rolled up toward the pillow portion 2.

In this way, by rolling up the main body 5 and engaging it with hook-and-loop fasteners 21 or the like, the air stretch exercise device 1 becomes compact and easy to carry. It also requires less storage space. Furthermore, by disengaging the hook-and-loop fasteners 21, the main body 5 can be released from the pillow 2, allowing the air stretch exercise device 1 to be easily laid out on the floor F or the like.

The air stretching exercise device 1 of the present invention is equipped with a seat 3 containing air bags 4 that can be used to treat various body parts. While lying supine on the seat 3 (main body 5), the air bags 4 can be inflated and deflated to perform stretching exercises on treatment areas such as the user's back K and buttocks D. In addition, the user can sit on the main body 5 with their upper body B in an upright position and perform pressure massages on treatment areas such as the thighs T and calves C of the legs L by inflating and deflating the air bags 4 (first air bag 10 to sixth air bag 22).

Furthermore, the air stretch exercise device 1 of the present invention can be stored smoothly and compactly because the sheet portion 3 (main body portion 5) can be rolled up. This configuration allows the user U to easily lay it out on the floor F or store it.
