Nursing device

technical field

The present disclosure relates to a care device for keeping the upper body of a care recipient in a stable state.

Background technique

When a care receiver such as a disabled person or an elderly person cannot maintain a sitting posture by his own strength while sitting on a toilet (Western-style toilet), for example, it is desirable to keep the upper body of the care receiver in a stable state. Therefore, Japanese Patent Application Laid-Open No. 6-33919 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2001-169968 (Patent Document 2) disclose that an auxiliary device for stabilizing the upper body is provided around the toilet bowl.

The assist device described in Patent Document 1 includes a pair of left and right ducts extending in the front-rear direction, located on the left and right of the care recipient sitting on the toilet, and a curved grab bar that connects the distal ends of the ducts to each other. In addition, Patent Document 1 also discloses the provision of a belt member for restraining the waist of a care-receiver who is sitting on the toilet and resting his back on the backrest board.

In the technical solution described in Patent Document 2, it is disclosed that a pair of left and right handrails, so-called handrails, extending in the front-rear direction and located on the left and right of the care-receiver sitting on the toilet, are provided so that the handrails can be swung in the up-down direction and can be selected. A use position extending in the front-rear direction and a to-be-avoiding position extending in the up-down direction can be obtained in a flexible manner. In addition, Patent Document 2 also discloses the provision of a belt member that restrains the upper body of a care-receiver who is sitting on the toilet and resting his back on a backrest board.

Utility model content

The problem to be solved by the utility model

The technical solutions described in each of the above-mentioned patent documents are based on the fact that unless a belt member for restraining the care receiver is used, the care receiver is a care receiver, that is, an arm or a fingertip that can perform actions such as grasping an auxiliary device. The premise is that the care receiver is able to exert force. However, some care recipients cannot perform actions such as grasping the assisting device. In this case, since the sitting posture cannot be maintained by one's own strength, even if there is an auxiliary device that can be grasped around, the auxiliary device cannot actually be used.

Here, in the invention of Patent Document 2, a belt member is used for a care receiver whose arms or fingertips cannot exert force, and the upper body of the care receiver is fixed to the backrest board. However, in reality, restraining the upper body with the belt member would restrain the care recipient, cause great mental distress to the care recipient, and also cause ethical problems, making it difficult to adopt.

The embodiment of the present invention takes the above circumstances into consideration, and an object thereof is to provide a care device that can reliably keep the upper body of a care receiver in a sitting position stable without being constrained by a belt member.

solutions to problems

In order to achieve the above objects, the embodiments of the present invention adopt the following solutions. which is,

have:

a base member, which is arranged in the vicinity of the seat on which the care recipient is seated;

a support member connected to the base member so as to be swingable in the up-down direction via a swing connection mechanism, and having a support portion that receives the front portion of the upper body of the care receiver seated on the seat in a state of extending in the horizontal direction; and

a swing angle changing mechanism for adjusting the swing angle of the support member relative to the base member,

The above-mentioned swing angle changing mechanism has:

a locking member provided on the base member and having a plurality of locking portions along a trajectory centered on a swing center of the support member;

an engaging member, which is displaceably provided on the supporting member, and which can acquire a locking position to be locked on the locking portion and an escape position to be withdrawn from the locking position;

an urging unit, which is provided on the support member and urges the engaging member toward the locking position; and

an operating member, which is provided on the supporting member and is used to displace the engaging member toward the position to be avoided against the urging unit,

The swing angle changing mechanism may change the height of the support portion by changing the swing angle of the support member by changing the locking portion that locks the engagement member among the plurality of locking portions.

According to the above-mentioned solution, the upper body of the care-receiver who is seated on the seat and tilted forward can be reliably supported by the support member. In addition, by changing the swing angle of the swing angle changing mechanism, it is possible to support at an appropriate forward inclination angle desired by the care receiver. Of course, since it is not restrained by a belt member, it does not cause mental distress to the person to be cared for, and it is not an ethical problem. In particular, when using a toilet seat, the person to be cared can maintain a posture that is particularly favorable for promoting bowel movements by bending over. In addition, since a large space is formed behind the upper body of the person to be cared for, it is easy for the care-receiver It is preferable to perform aftercare work such as buttock cleaning after bowel movements.

The solution premised on the above solution is as follows.

The support member can have a side frame portion positioned on the side of the care recipient seated on the seat portion, and the support portion can be provided with a side frame portion extending in the horizontal direction from a front end portion of the side frame portion and positioned on the seat portion. The front arm is formed in front of the upper body of the care recipient. In this case, the upper body of the care receiver in the sitting position can be prevented from falling forward by the front arm portion, and the upper body of the care receiver can be supported more stably by the side frame portion preventing side fall.

In the support member, the vicinity of the rocking connection mechanism can be configured as a pipe portion having a front end opening, and the engaging member is disposed in the pipe portion and opens from the front end at least when set to the locking position. Prominent. In this case, the engaging member can be easily held by the pipe material.

The swing angle changing mechanism can be configured to change the locking portion that locks the engaging member regardless of the operation of the operating member when an external force for swinging the support member in the forward upward direction is applied. In this case, unless the operating member of the swing angle changing mechanism is operated in the direction of drooping forward in an uncomfortable posture and a sense of restraint is easily felt, the rocking cannot be performed, and the support member can be reliably prevented from drooping excessively. In addition, the swinging of the support member in the forward lifting direction is allowed without operating the operation member of the swing angle changing mechanism, that is, the operation member without operating the swing angle changing mechanism can easily swing from an uncomfortable posture to the release direction , which is preferable in terms of releasing the sense of restraint. In particular, it is also preferable to quickly return to the preferred forward inclination angle desired by the care receiver when the care receiver maintains a stooped posture due to excessive forward leaning and the like is uncomfortable.

The swing angle changing mechanism may be configured to allow the support member to swing in the forward raising direction and sag in the forward direction only when the operation member is operated to release the locking of the engagement member by the locking portion. direction swing. In this case, the swinging of the support member in the forward direction and the forward vertical direction is made impossible unless the operation member of the swing angle changing mechanism is operated, so that the swing angle of the support member can be reliably maintained at the desired position. The desired angular aspect is preferred.

The plurality of locking portions can be formed of a plurality of concave portions formed so as to sandwich the convex portion. In this case, the locking portion can be simply constituted by the concave portion and the convex portion.

Each of the plurality of the convex portions can have a predetermined one of the side surfaces in the arrangement direction of the plurality of concave portions as inclined surfaces, and the engaging member can be formed when an external force swinging in the forward direction is applied to the support member. Go over the convex portion while following the inclined surface. In this case, unless the operating member of the swing angle changing mechanism is operated in the direction of drooping forward in an uncomfortable posture and a sense of restraint is easily felt, the rocking cannot be performed, and the support member can be reliably prevented from drooping excessively. In addition, the swinging of the support member in the forward lifting direction is allowed without operating the operation member of the swing angle changing mechanism, that is, the operation member without operating the swing angle changing mechanism can easily swing from an uncomfortable posture to the release direction , which is preferable in terms of releasing the sense of restraint. In particular, it is also preferable to quickly return to the preferred forward inclination angle desired by the care receiver when the care receiver maintains a stooped posture due to excessive forward leaning and the like is uncomfortable.

The plurality of locking portions can be a plurality of locking holes into which the distal end portions of the engaging members are inserted. In this case, the locking portion can be simply configured as a locking hole.

The front end portion of the engaging member may be formed such that a predetermined one of the side surfaces in the arrangement direction of the plurality of locking holes is an inclined surface, and the front end portion of the engaging member is inserted into the locking hole. When an external force is applied to the support member to swing in the forward direction, the engaging member can be disengaged from the locking hole while the inclined surface is aligned with the inner peripheral edge portion of the locking hole. In this case, unless the operating member of the swing angle changing mechanism is operated in the direction of drooping forward in an uncomfortable posture and a sense of restraint is easily felt, the rocking cannot be performed, and the support member can be reliably prevented from drooping excessively. In addition, the swinging of the support member in the forward lifting direction is allowed without operating the operation member of the swing angle changing mechanism, that is, the operation member without operating the swing angle changing mechanism can easily swing from an uncomfortable posture to the release direction , which is preferable in terms of releasing the sense of restraint. In particular, it is also preferable to quickly return to the preferred forward inclination angle desired by the care receiver when the care receiver maintains a stooped posture due to excessive forward leaning and the like is uncomfortable.

The pair of left and right support members can be provided so as to sandwich the care receiver, and the pair of left and right support members are connected to each other by a connecting member located behind the care receiver, and are configured to swing integrally with each other. In this case, by connecting the pair of left and right support members to each other by the connecting member, the rigidity can be sufficiently improved as a whole, which is preferable in terms of stably holding the upper body of the care-receiver. In addition, backward fall of the care recipient can be prevented by the connecting member. Further, by swinging only one of the left and right support members, the other support member can be swingable in conjunction with each other. In addition, the swing angle changing mechanism can be provided only on one of the left and right support members, and in this case, the operation of changing the swing angle becomes easy. In addition, it is also possible to provide a swing angle changing mechanism to the support members on both the left and right sides, and in this case, it is preferable to firmly maintain a desired swing angle.

A buffer member capable of swinging in the vertical direction can be attached to the support portion of the support member. In this case, the upper body of the care-receiver in the sitting position can be flexibly caught by the cushion member, and it is preferable in that the care-receiver can be supported without causing pain or the like. In addition, the cushioning member supporting the upper body of the care-receiver can be appropriately swung according to the change in the swing angle of the support member or the physique of the care-receiver, so that the care-receiver can always be supported in the optimal posture of the cushioning member.

The seat is provided on the toilet, and the base member includes a pair of left and right vertical rod-shaped members extending in the vertical direction, and a gap adjustment member for filling a gap with the toilet is attached to the pair of left and right vertical rod-shaped members.

The side frame portions are a pair of left and right, and the pair of left and right side frame portions are slightly inclined so that the width between them is narrowed toward the upper side.

Detailed ways

1-3 shows an example of the care apparatus K which concerns on embodiment of this invention. In FIGS. 1-3, the state which arrange|positioned the care apparatus K in the toilet bowl 1 is shown.

The care device K roughly includes a base member 10 , a pair of left and right side frame portions 20 , a pair of left and right front arm portions 30 , a rear frame portion 40 , and a swing connection mechanism 50 . The support member is constituted by the side frame portion 20 and the front arm portion 30 .

The base member 10 includes a pair of left and right vertical rod-shaped members 11 extending in the vertical direction, a horizontal rod-shaped member 12 extending in the left-right direction and connecting the upper ends of the left and right pair of vertical rod-shaped members to each other, and the vertical rod-shaped member. The mounting plate portion 13 at the lower end of the 11 has a gate shape as a whole. The rear part of the toilet seat 1 is arranged in the space below the horizontal rod-shaped member 12 between the pair of left and right vertical rod-shaped members 11 . The base member 10 is a floor-standing type that does not affect the structure of the toilet 1, that is, the flush valve or the low-level water tank. In addition, the base member 10, more specifically, the mounting plate portion 13 of the base member 10 may be arranged in the vicinity of the toilet bowl 1, and can be fixed to the toilet bowl 1 or to a floor surface.

The side frame parts 20 are provided with a pair of left and right, and are formed by bending a pipe material. In addition, the pipe material described below is composed of, for example, a metal core material such as SUS and a synthetic resin cover, but is not limited to this. Each side frame portion 20 generally includes an upper frame portion 21 extending in the front-rear direction, and a lower frame portion 22 extending downward from the front end of the upper frame portion 21 and then extending rearward. Further, the rear end portion of the lower frame portion 22 is swingably attached to the vertical rod-shaped member 11 via a swing connection mechanism 50 as described later.

The rear end portions of the upper frame portion 21 of the pair of left and right side frame portions 20 are connected to each other by a rear frame portion 40 extending in the horizontal direction in the left-right direction. In the embodiment, the side frame portion 20 and the rear frame portion 40 are integrally formed with the same pipe material. The pair of left and right side frame portions 20 are connected by the rear frame portion 40, whereby the overall rigidity is improved, and by swinging one of the side frame portions 20, the other side frame portion 20 also swings in conjunction therewith. .

Referring also to Figs. 4 and 5 , the swing coupling mechanism 50 and the swing angle changing mechanism 60 related thereto will be described. First, the swing connection mechanism 50 includes a connection bracket 51 fixed to the vertical rod-shaped member 11 of the base portion 10 . The side frame portion 20 , more specifically, the rear end portion of the lower frame portion 22 of the side frame portion 20 is connected to the connection bracket 51 via the connection portion 52 so as to be swingable in the vertical direction. In addition, the connection part 52 is comprised by a suitable method, such as being comprised by the connection pin with a screw thread and the nut screwed together, for example.

A plate-shaped upper limit portion 53 and a pin-shaped lower limit portion 54 are formed in the connecting bracket 51 in order to constitute the swing stroke end of the side frame portion 20 . Each of the stopper portions 53 and 54 is set to form an angle of approximately 45 degrees with the connection portion 52 as the center. The side frame portion 20 swings around the connection portion 52, whereby the angle of the front hanging (forward inclination angle) can be changed. However, when the rear end portion of the lower frame portion 22 comes into contact with the upper and lower stopper portions 53 or 54 , swinging beyond the stopper portions 53 and 54 is restricted. In addition, when the lower frame portion 22 is in contact with the lower stopper portion 54, the upper frame portion 21 is in a basic posture state extending in the front-rear direction in a horizontal state.

The swing angle changing mechanism 60 for changing the swing angle of the side frame portion 20 is provided only on one side frame portion 20 . As shown in FIGS. 4 and 5 , the swing angle changing mechanism 60 has a locking member 61 integrated with the connecting bracket 51 . The locking member 61 is formed of, for example, metal such as SUS or synthetic resin, and is fixed to the connecting bracket 51 by a clip 62 .

The locking member 61 has an arc-shaped surface centered on the connection portion 52 , and a plurality of locking concave portions 63 are formed at the same angle along the circumferential direction on the arc-shaped surface. The locking convex portions 64 are located between the adjacent locking concave portions 63 .

As shown in FIGS. 6 and 7 , an engaging member 65 is slidably held in the rear end portion of the lower frame portion 22 of the side frame portion 20 . The engaging member 65 includes a main body portion 65a that is plate-shaped and slidable with respect to the inner surface of the lower frame portion 22, and an extending portion 65b that extends backward from the main body portion 65a, that is, to the back side of the lower frame portion 22. An elongated hole-shaped guide hole 65c extending in the sliding direction of the engaging member 65 is formed in the extending portion 65b. Moreover, the engagement protrusion part 65d extended toward the locking member 61 is formed from the main-body part 65a. According to the sliding movement of the engaging member 65 , the engaging protrusion 65d can be fitted (locked) and released (disengaged) with respect to the locking recessed portion 63 .

The guide pin 66 which penetrates the said guide hole 65c is fixed to the lower frame part 22. As shown in FIG. The engaging member 65 can be displaced within a range in which the guide pin 66 slides in the guide hole 65c. In FIGS. 6 and 7 , the state of the locking position where the engaging member 65 protrudes most from the lower frame portion 22 is shown. The guide pin 66 penetrates the guide hole 65c without rattling, and restricts the rotation of the plate-shaped engaging member 65 in the circumferential direction of the lower frame portion 22.

Inside the lower frame portion 22, a return spring 67 composed of a coil spring is arranged as an urging means. The return spring 67 is located between the guide pin 66 and the main body portion 65a, and is disposed so as to wrap around the extending portion 65b. The engaging member 65 is always urged by the return spring 67 in a direction protruding from the lower frame portion 22 , that is, a direction in which the engaging member 65 is fitted into the locking recess 64 .

An operation member 68 is held in a portion of the lower frame portion 22 extending in the vertical direction so as to be slidable in the vertical direction. The operation member 68 has a cylindrical portion 68a slidably fitted to a portion extending in the vertical direction of the side frame portion 20, and an operation portion 68b integrated with the cylindrical portion 68a. A guide pin 69 integrated with the cylindrical portion 68a is slidably fitted in a guide hole 70 formed in the side frame portion 20 and extending short in the vertical direction.

The guide pin 69 and the extending portion 65 b of the engaging member 65 are connected by a connecting wire 71 arranged in the lower frame portion 22 . As a result, the engaging member 65 can be displaced in the locking releasing direction pulled into the lower frame portion 22 against the return spring 67 by gripping the operating portion 68b of the operating member 68 and sliding it upward.

The upper side surface of the plurality of locking protrusions 64 is an inclined surface 64 a that gradually goes downward as it goes toward the front end. On the other hand, the lower side surface of the locking convex portion 64 has a shape that is steep at a substantially right angle, and is not formed with an inclined surface.

Now, assume a state in which the side frame portion 20 is slightly drooped forward than the state shown in Figs. In this state, even if a large external force is applied to swing the side frame portion 20 in the direction that it hangs forward, that is, in the counterclockwise direction in FIGS. 4 and 5 , the swing is firmly restricted by the locking protrusions 64 .

On the other hand, when a moderate external force is applied to swing the side frame portion 20 in the direction of raising forward, that is, in the clockwise direction in FIGS. 4 and 5 , the engaging protrusion 65d of the engaging member 65 can be moved to It goes over the locking convex portion 64 while following the inclined surface 64 a of the locking convex portion 64 . In this way, in the present embodiment, the swing of the side frame portion 20 in the front vertical direction is firmly restricted, while the swing in the forward lift direction is allowed.

Next, the relationship between the side frame portion 20 and the front arm portion 30 will be described. First, the front arm portion 30 is formed into a substantially L-shape by bending a pipe material. That is, the front arm portion 30 has a main body portion 31 along the upper frame portion 21 of the side frame portion 20 , and a support arm portion 32 that is bent at approximately 90 degrees from the main body portion 31 and extends. Such front arm portions 30 are respectively provided on the left and right side frame portions 20 .

The main body portion 31 is swingably attached to the upper frame portion 21 . Thereby, the front arm portion 30 can selectively acquire the use position in which the support arm portion 32 extends in the horizontal direction, that is, the position indicated by the solid line in FIGS. The position indicated by the dashed-dotted line in Fig. 1 and Fig. 2 . In addition, the swing of the front arm portion 30 can be locked by a lock mechanism 90 to be described later in the retracted position.

From the viewpoint of versatility and the like, the interval between the pair of left and right vertical rod-shaped members 11 of the base member 10 is set sufficiently larger than the width of the toilet bowl 1 . Therefore, in the front view shown in FIG. 1, the pair of left and right side frame parts 20 are slightly inclined so that the width becomes gradually narrower toward the upper side. Moreover, the clearance adjustment member 14 which fills the clearance gap with the toilet bowl 1 is attached to a pair of left and right vertical rod-shaped members 11.

Here, buffer members 80 are attached to the pair of left and right support arm portions 32 (see FIGS. 1 to 3 ). The attachment structure of the buffer member 80 will be described with reference to FIGS. 8 to 10 .

First, the buffer member 80 has a base plate 81 made of, for example, aluminum alloy or synthetic resin, and an elastic member 82 integrated therewith so as to cover one surface side of the base plate 81 , such as a member having elasticity such as rubber or urethane. The base plate 81 has a curved portion 81a curved in an arc shape, and a pair of flange portions 81b extending from each end portion of the curved portion 81a. In addition, the substrate 81 can be formed by, for example, injection molding synthetic resin.

The bent portion 81 a is bent over 180 degrees, and the opening width thereof is smaller than the outer diameter of the support arm portion 32 . The cushion member 80 is attached to the support arm portion 32 by elastically deforming the curved portion 81 a to fit the support arm portion 32 with the opening width thereof expanded. The elastic member 82 of the buffer member 80 is arranged so as to face the care receiver P sitting on the toilet bowl 1 .

The base plate 81 can swing by a predetermined angle relative to the support arm portion 32 . That is, the guide pin 83 which consists of a bolt is fixed to the support arm part 32, and a part of the guide pin 83 protrudes from the outer surface of the support arm part 32. On the other hand, on the inner surface of the bent portion 81a of the base plate 81, a guide hole 81c extending in the circumferential direction thereof is formed. The above-mentioned guide pins 83 protrude into the guide holes 81c. The buffer member 80 can swing with respect to the support arm portion 32 within a range in which the guide pin 83 can move within the guide hole 81 c. In FIG. 9, the shock absorbing member 80 in the state located at the rocking stroke end is shown by a two-dot chain line. Furthermore, since the guide pins 83 protrude into the guide holes 81c, the axial displacement of the buffer member 80 to the support arm portion 32 is restricted.

By the buffer member 80 attached to the support arm 32 , more specifically, the elastic member 82 of the buffer member 80 , the upper body of the care receiver is softly caught, and pain and the like for the care receiver can be prevented. The buffer member 80 attached to the support arm 32 can be appropriately swung according to the change in the swing angle of the side frame portion 20 or the physique of the care recipient, so that the elastic member 82 is always in a posture favorable for support.

The buffer member 80 is also attached to the rear frame portion 40 in the same manner as in the configuration shown in FIGS. 8 and 9 . The buffer member 80 attached to the rear frame portion 40 is swingable in the vertical direction. When the care receiver leans against the rear frame portion 40 , the upper body of the care receiver is flexibly caught by the buffer member 80 attached to the rear frame portion 40 , thereby preventing pain and the like for the care receiver. In addition, the buffer member 80 attached to the rear frame portion 40 can be appropriately swung according to the change in the angle of the rear frame portion 40 or the physique of the care recipient, so that the elastic member 82 can always be in a posture favorable for support. .

Furthermore, the buffer member 80 is also attached to the upper frame part 21 of the side frame parts 20, and more specifically, the connection bracket 100 to be described later fitted with the upper frame part 21 (see FIGS. 11 and 12 ). However, the buffer member 80 for the upper frame portion 21 is of a fixed type that cannot swing in the vertical direction. Thereby, when the care-receiver is about to fall sideways, it can be flexibly received by the buffer member 80 attached to the upper frame portion 21 .

Next, focusing on the locking mechanism 90 for locking the front arm portion 30 in the retracted position, the attachment of the front arm portion 30 to the side frame portion 20 will be described with reference to FIGS. 11 to 14 .

First, the rear end portion of the main body portion 31 of the front arm portion 30 is constituted by the connecting member 33 . The connecting member 33 is formed by, for example, extruding an aluminum alloy, and is fixed to the main body portion 31 made of a pipe material with a jig 34 such as a bolt.

The cross-sectional shape of the said connection member 33 is shown in FIG.11, FIG.12. The connecting member 33 has a shape including a locking groove 33a and a first stopper portion 33b and a second stopper portion 33c each constituted by a protruding portion, as shown in its cross-sectional shape.

The front arm part 30 , more specifically, the main body part 31 of the front arm part 30 and the side frame part 20 , more specifically, the upper frame part 21 of the side frame part 20 are connected by the connecting bracket 100 . That is, the connection bracket 100 has a first cylindrical portion 101 to which the main body portion 31 of the front arm portion 30 is rotatably fitted, and a second cylindrical portion 102 to which the upper frame portion 21 of the side frame portion 20 is fitted.

The part of the connection bracket 100 in the second cylindrical part 102 has a structure in which the first member 100A and the second member 100B are divided into two parts. Also, the two parts 100A and 100B are fastened by bolts 103 and nuts 104 penetrating the upper frame portion 21 . In addition, the upper frame portion 21 and the connection bracket 100 are integrated with bolts 103 and nuts 104 .

The swing lever 110 is swingably attached to the connection bracket 100 via the pin member 111 . One end portion of the rocking lever 110 is a locking claw portion 110 a that can be fitted (locked) to the locking groove 33 a of the above-described connecting member 33 . And, the rocking lever 110 is urged|biased by the spring 112 which is an urging|biasing means in the direction which fits the locking claw part 110a and the locking groove 33a. In the embodiment, the spring 112 is composed of a leaf spring, and is interposed between the swing rod 110 and the connecting bracket 100 .

The swing lever 110 has an operation portion 110b. By operating the operation portion 110b in the clockwise direction in Fig. 11 , the engagement of the locking pawl portion 110a with the locking groove 33a is released (unlocked).

A first stepped portion 101a and a second stepped portion 101b are formed on the inner surface of the first cylindrical portion 101 of the connecting bracket 100 at intervals in the circumferential direction. As shown in FIG. 11 , the position where the first stopper portion 33b of the connecting member 33 abuts against the first step portion 101a corresponds to the position to be avoided. Moreover, as shown in FIG. 12, the position where the 2nd stopper part 33c of the connection member 33 abuts with the 2nd step part 101b corresponds to a use position.

To change the front arm portion 30 from the evacuated position to the use position, it is only necessary to operate the operation portion 110b of the swing lever 110 to disengage the locking claw portion 110a from the locking groove 33a of the coupling member 33 .

The front end surface of the locking claw portion 110a is a flat surface. In addition, let the predetermined position in the outer peripheral surface of the connection member 33 be the flat surface 33d. In FIG. 12 corresponding to the use position, the front end surface of the locking claw portion 110a is in contact with the flat surface 33d of the connecting member 33, and the front arm portion 30 is stably held in the use position. However, the front arm portion 30 can be easily set to the retracted position by applying an appropriate external force toward the retracted position to the front arm portion 30 in the use position.

The displacement of the connection bracket 110 relative to the connection member 33 in the axial direction thereof is restricted. That is, although not shown in the drawings, a restricting member that abuts the side surface of the connecting bracket 10 is attached to the front end of the connecting member 33 , and the one end surface of the connecting member 110 is restricted from being disengaged from the connecting member 33 . In addition, the other end surface of the connection bracket 110 is in contact with the end surface of the main body portion 31 made of a pipe material.

Next, the usage method of the care apparatus K arrange|positioned in the toilet bowl 1 is demonstrated. First, in the state before use, the front arm portion 30 is in the evacuated position, that is, in the state indicated by the dashed-dotted line in FIGS. 1 and 2 , the front of the toilet bowl 1 is wide open. In addition, the side frame portion 20 is in a basic posture state in which it is not inclined forward, for example, the state shown in FIG. 2 . In this state, the care receiver P receives the care of the caregiver, and sits on the seat portion 1 a of the toilet seat 1 .

After the care receiver P sits on the seat portion 1a, the front arm portion 30 is set to the use position. In the use position, the support arm portion 32 of the front arm portion 30, more specifically, the buffer member 80 attached to the support arm portion 32 is positioned directly in front of the front portion of the upper body of the care recipient P (see FIG. 3 ). Accordingly, when the upper body of the care receiver P falls forward, it is supported by the front arm portion 30, and the care receiver P can be prevented from falling forward.

When the upper body of the care recipient P sitting on the seat portion 1a falls backward, the upper body is supported by the rear frame portion 40, and the upper body can be prevented from falling backward. In addition, the pair of left and right side frame parts 20 can prevent the care receiver P sitting on the seat part 1a from falling down.

In order to promote defecation, especially defecation, it is preferable that the care receiver P is in a state where the waist is greatly bent. At this time, the caregiver only needs to operate the operation member 68 to release the locking action of the swing angle changing mechanism 60, and to tilt the side frame portion 20 and the front arm portion 30 and the rear frame portion 40 integral therewith to a desired forward tilt angle. That's it. After the desired forward inclination angle is reached, the operation of the operation member 68 is released, and the swinging position of the side frame portion 20 is restricted.

FIG. 3 shows a state in which the side frame portion 20 is tilted forward by about 20 degrees from the basic posture state. The care receiver P is supported by the front arm 30 in a bent state. By bending the care receiver P, the posture is particularly favorable for promoting bowel movements, and since a large space is formed behind the upper body of the care receiver P, the care receiver can easily perform buttock cleaning after defecation, etc. Aftermath work.

Since the front arm 30 in the use position is not locked to swing to the sheltered position, the caregiver or the care receiver P with free arms can smoothly set the front arm 30 to the sheltered position. In particular, when the care receiver P can use the arms, the front arm 30 can be smoothly swung to the avoidance position according to the intention of the care receiver P, thereby preventing or suppressing the feeling of being restrained by the care receiver P. aspect is also preferred.

When the side frame portion 20 is tilted forward as shown in FIG. 3 , the care receiver P leans his body weight on the rear frame portion 40 as desired, and the locking of the swing angle changing mechanism 60 is caused by the locking convex portion 64 . The function of the inclined surface 64a of the 1 is automatically released, and it can move in the direction of reducing the forward inclination angle of the side frame portion 20, and can also return to the basic posture state shown in FIG. 2 . It is also preferable to prevent or suppress the feeling of being restrained from being given to the care receiver P because the forward inclination angle of the side frame portion 20 can be easily narrowed based on the care receiver P's own thoughts. In addition, even when the care receiver P maintains an uncomfortable stooped posture due to excessive forward leaning, it is possible to quickly return to the preferred forward leaning angle desired by the care receiver P.

After defecation is completed, the side frame portion 20 is set to the basic posture state not tilted forward, that is, the state shown in FIG. 2 , and the front arm portion 30 is set to the avoidance position, such as the state shown in FIG. 1 . After that, the care recipient P receives the care of the caregiver, and leaves the toilet seat 1 .
