Description

commercial devices

This specification relates to a commercial device that monitors the actions of a subject.

As our aging society progresses, the demand for assistive devices is increasing. Many assistive devices assist the various movements of the person receiving assistance by operating a support member that supports a portion of the person's body. Furthermore, assistive devices are equipped with casters for mobility, allowing the person riding the device to be moved. The introduction of assistive devices not only reduces the physical burden on both the person receiving assistance and the assistor, but also alleviates the shortage of caregivers.

Since a water-based device used for purposes such as washing a person's body is assumed to be used in a bathroom or shower room, it is necessary to have a structure that takes into account the presence of moisture. For example, Patent Document 1 discloses a water-based device used in a bathroom to wash a person's body. This water-based device includes a lower leg contact portion covered entirely with a highly waterproof cushioning material, and a foot contact surface that is treated to prevent the person's feet from slipping, such as by forming a rough surface or applying a coating. According to this, it is possible to configure a water-based device suitable for use in a bathroom.

International Publication No. 2020/115857

However, although the commercially available device of Patent Document 1 has waterproof specifications for the lower leg contact area and anti-slip processing for the foot rest surface, it cannot be said that sufficient consideration has been given to moisture. If moisture remains in the commercially available device, it can lead to concerns about the growth of bacteria and become unsanitary, so it is necessary to adopt a shape that makes it easy for attached water droplets to flow out of the device. Furthermore, if the anti-slip processing shape is inappropriate, it can hinder drainage, which can be counterproductive to the outflow of water droplets. Furthermore, there are areas other than the lower leg contact area that require waterproof specifications. For example, if moisture penetrates the sliding portion of the moving part, it can cause malfunction.

Therefore, the challenge of this specification is to provide a commercially available device suitable for use in a bathroom or shower room where moisture is present.

The present specification discloses a loading device comprising a base, a loading execution unit that loads the movement of a loader riding on the base, and a foot loading member installed on the base for the loader to place his/her foot on, the foot loading member having a slope that decreases from the center toward the periphery at least when the loader does not place his/her foot on the base.

In addition, the present specification discloses a riding device comprising a stand, a riding execution unit for riding the stand, and a foot-holding member installed on the stand for the stand to place the foot, the foot-holding member having a plurality of protrusions installed on the upper surface to prevent the foot of the stand from slipping.

In addition, the present specification discloses a riding device having a support, a fixed part, and an extendable moving part having a moving part that extends with respect to the fixed part, a riding execution part that supports the movement of a person riding on the support, and a cover member that prevents wetting of a sliding part where the fixed part and the moving part slide.

In addition, this specification discloses a technical idea in which “the commercially available device described in claim 1 or 2” in claim 4 of the original application is changed to “the commercially available device described in any one of claims 1 to 3.”

According to the disclosed commercial device, water droplets flow out of the device along a slope from the center to the periphery of the footrest member, thereby suppressing moisture retention, thereby inhibiting the growth of germs, and maintaining good hygiene. In addition, since a plurality of anti-slip protrusions are provided on the upper surface of the footrest member, slipping of the user's feet is suppressed even if moisture remains. In addition, since the covering member is provided, wetting of the sliding portion of the expansion/contraction unit can be prevented, so that malfunction of the expansion/contraction unit due to moisture does not occur. Therefore, the commercial device is suitable for use in bathrooms or shower rooms, etc., where moisture is constantly present.

1. Overall configuration of the commercial device (1) of the embodiment

The overall configuration of the assist device (1) of the embodiment will be described with reference to FIGS. 1 to 3. As indicated by the arrows on the upper right of FIG. 1, the front, back, left, and right of the assist device (1) are determined. The front (right side in FIG. 1) of the assist device (1) is the main driving direction when the assist device (1) is moved, and the rear (left side in FIG. 1) of the assist device (1) is the rear of the boarding direction in which the person being assisted boards the assist device (1). The assist device (1) is used for transferring between two indoor locations, such as between the bed of the person being assisted and a wheelchair, or between a wheelchair and a toilet seat. In addition, the assist device (1) is also used for moving when the two locations being transferred are separate. For example, the assist device (1) is used for moving the person being assisted from the living room to a bathroom, dining room, restroom, etc.

The support device (1) supports the upper body of the person being supported, and supports the standing movement from a sitting position to a standing position, and the sitting movement from a standing position to a sitting position. Here, the standing position means a position in which the buttocks are raised from the seated surface and the legs are stretched, and includes a standing position and a crouching position. That is, the standing position includes a standing position in which the upper body is generally upright, and a forward bending position in a crouching position in which the upper body is tilted forward. In addition, the support device (1) is configured to be suitable for use in a bathroom or shower room where moisture is constantly present. As shown in FIGS. 1 and 2, the commercial device (1) is composed of a base (2), a foot support member (3), an arm member (5), a support member (6), a driving member (7), and a control member (not shown).

The base (2) is the part where the pilot gets on. The base (2) is equipped with a footrest member (3), an arm member (5), and a driving member (7). The base (2) is formed by a left and right pair of pipe frames (21), a left and right pair of assembly frames (22), a left and right pair of front plate frames (23), a back plate frame (24), etc. The pipe frame (21) is formed by bending a metal pipe. The middle portion (212) of the left and right pairs of pipe frames (21) extends horizontally in the front-back direction at a position slightly higher than the floor surface S, and is arranged in parallel and spaced apart from each other. The front portion (211) of the pipe frame (21) is bent upward. A set of left and right assembly frames (22) in the shape of a standing plate are installed on the front side of the entire body (211) of a set of pipe frames (21).

On the upper part of a set of assembly frames (22), a swaying support seat (29) is installed. On the lower part of a set of assembly frames (22), a set of left and right front casters (25) is installed. That is, the front casters (25) are installed on the front of the base (2). On the upper part of the front part (211) of a set of pipe frames (21), a set of left and right position adjustment parts (281) is installed. The position adjustment parts (281) are manual adjustment mechanisms that allow a person, etc., to adjust the front-back position of the knee contact member (28) according to the physique of the person being examined.

The knee contact member (28) is located above the middle portion (212) of the pipe frame (21) and is the part where the knee of the subject comes into contact. The knee contact member (28) stabilizes the standing or sitting motion of the subject by determining the position of the knee. The knee contact member (28) is formed by a base plate (282), a knee contact body (283), and two connecting rods (284). The base plate (282) is formed to extend in the left-right direction using a metal plate, and is arranged to be slightly inclined forward rather than vertically. The knee contact body (283) is formed of an elastically deformable urethane foam or the like, and is mounted on the rear side of the base plate (282). The two connecting rods (284) are formed using a metal bar, and connect the base plate (282) to the left-right position adjustment parts (281).

As shown in Fig. 3, the middle part (212) of the pipe frame (21) is connected by an auxiliary pipe (214) extending in the left-right direction. The auxiliary pipe (214) is made of the same material as the pipe frame (21) and has the same diameter. A drive unit mounting seat (216) is installed between the left and right middle parts (212) in front of the auxiliary pipe (214). The lower part of the drive unit (7) is mounted on the drive unit mounting seat (216). The rear parts (213) of the left and right sets of pipe frames (21) are formed by being bent inward. The bent ends of the left and right rear parts (213) are connected and integrated. The connecting part of the middle part (212) and the auxiliary pipe (214), and the connecting part of the rear parts (213) are connected by, for example, welding.

The rear plate frame (24) is formed of a metal plate-shaped member that is long in the left-right direction. The rear plate frame (24) is fixed to the upper portion of the rear portion (213) of the pipe frame (21) by welding. A pair of left-right rear casters (27) are installed on the lower surface of the rear portion of the rear plate frame (24). That is, the rear casters (27) are installed at the rear portion of the base (2) in the boarding direction.

A set of left and right front plate frames (23) are each formed using metal plate-shaped members. The front plate frames (23) are fixed to a position near the front of the middle part (212) of the pipe frame (21) by welding and are arranged to protrude outward. Caster mounting holes (231) are installed near the outside of the left and right front plate frames (23). A set of left and right intermediate casters (26) are installed below the left and right caster mounting holes (231). That is, the intermediate casters (26) are installed between the rear casters (27) and the front casters (25) of the base (2).

The footrest member (3) is the part where the rider places his or her foot to board. The footrest member (3) is formed thinly so as to extend horizontally in two directions and is mounted on the upper side of the pipe frame (21). Details of the footrest member (3) will be described later.

The arm member (5), as shown in Fig. 1, is formed in a shape that is bent in the middle when viewed from the side. In Figs. 1 and 2, the outer cover of the arm member (5) is not illustrated. A swing shaft (51) is installed near the lower portion of the arm member (5). The swing shaft (51) is swingably supported on swing support seats (29) of the left and right assembly frames (22). In order to regulate the swing angle range of the arm member (5), a stopper mechanism (not illustrated) is installed near the swing support seats (29). As a result, the arm member (5) can swing in the up-front and down-backward directions with the swing support seats (29) of the base (2) as the swing center. The arm member (5) swings in the up-front direction during the standing motion of the subject (clockwise swing in Fig. 1). In addition, the rocker arm (5) swings in the downward direction when the PC user sits down.

A battery (not shown) and a link mechanism are stored inside the arm member (5). The battery serves as a power source for the driving unit (7) and the control unit. A swing member (52) is installed on the upper rear side of the arm member (5). The swing member (52) swings with respect to the arm member (5). However, in the initial state before the subject comes into contact with the support member (6), the swing member (52) is controlled by the link mechanism and does not swing. In addition, the applicant of the present application discloses a detailed configuration example of the link mechanism in International Publication No. 2018/167856.

The swing member (52) has a base plate (53) on the rear side. The base plate (53) is formed in a generally rectangular shape using a rigid metal or resin plate. The base plate (53) has a handle (54) on the front surface. The handle (54) is formed in a generally rectangular frame shape and extends upward from the arm member (5). The handle (54) is a part that is held by the user and is also a part that is held by the user to move the swing device (1).

A support member (6) is installed on the rear side of the base plate (53). The support member (6) moves relative to the base (2) while supporting a part of the body of the subject. The support member (6) is configured to include an upper body support member (61) and a pair of left and right armpit support members (62). The upper body support member (61) is mounted on the rear side of the base plate (53). The upper body support member (61) is formed by laminating a hard cushion member and a soft cushion member (not shown). The upper body support member (61) supports the upper body of the subject, mainly from the chest to the abdomen.

A pair of left and right armpit supports (62) are mounted on the base plate (53) and arranged on both left and right sides of the upper body support (61). The armpit supports (62) are formed in an L-shape that is bent at an obtuse angle. The armpit supports (62) are formed of a core member and an outer peripheral member (not shown). The armpit supports (62) enter the armpit of the PC center and support the upper body. The upper body support (61) and the armpit supports (62) may be covered with a protective cover made of cloth or leather.

The driving part (7) drives the arm member (5) and the support member (6). As the driving part (7), a linear actuator having a fixed part (71) and a movable part (72) is used. The linear actuator is a type of elastic operating part having a fixed part (71) and a movable part (72) that expands and contracts with respect to the fixed part (71). The fixed part (71) is a stepped cylindrical member that is long in the vertical direction and has an opening at the top. The lower end of the fixed part (71) is mounted on the driving part mounting seat (216) of the base (2). The movable part (72) is a round rod-shaped member that is long in the vertical direction and has a small diameter. The upper end of the movable part (72) is connected to a link member (57) of a link mechanism (see Fig. 10). The lower part of the movable part (72) is engaged with the opening of the fixed part (71).

A motor (711) is installed on the front side of the large diameter portion at the bottom of the fixed portion (71). The direction of current flow of the motor (711) is controlled by the control portion, and drives the extension and contraction motions of the movable portion (72). As a result, the movable portion (72) performs an extension motion with respect to the fixed portion (71). The driving portion (7) performs a first extension motion for extending from a minimum length to a predetermined intermediate length, and a second extension motion for extending from the intermediate length to a maximum length.

By the first extension operation of the driving unit (7), the support member (6) is driven through the link mechanism and swings upward. By the second extension operation of the driving unit (7), the arm member (5) is driven through the link mechanism and swings upward. In this way, the support member (6) moves upward with respect to the base (2) and also moves forward. By this, the support device (1) supports the standing motion of the person being watched. In addition, by the contraction operation of the driving unit (7), the arm member (5) swings downward and backward, and the support member (6) moves downward and also moves backward. By this, the support device (1) supports the sitting motion of the person being watched.

The control unit of the urban omission is composed of an operator and a control main body, etc. The operator has an up button and a down button for operating a driving unit (7). The operator is operated by a user. The control main body is a computer device having a CPU and operating with software. The control main body controls the current flowing to the motor of the driving unit (7) according to the operation information of the up button and the down button. As a result, the operation and stop of the driving unit (7), and the switching between the extension and contraction operations are controlled. As can be seen from the explanation up to this point, the arm member (5), the support member (6), and the driving unit (7) constitute a driving execution unit that operates the standing and sitting movements of the user.

Here, in many bathrooms or shower rooms, steps are installed at the entrance to prevent water leakage, and drainage grooves or drain holes and gentle slopes are installed on the floor surface S. In other words, the floor surface S of the bathroom or shower room is not an ideal flat surface because it has steps, unevenness, and slopes. On the other hand, since the floor surface S is wet with water, the casters, etc. are prone to slipping. However, as shown in Fig. 1, since the wheel diameter of the front caster (25) is larger than that of the middle caster (26) and the rear caster (27), the drivability of the commercial device (1) when it runs forward is improved. In particular, the commercial device (1) has good drivability, such as when it runs over steps or unevenness of the non-ideal floor surface S in the bathroom, or when it runs stably on the floor surface S that is prone to slipping when wet with water.

Meanwhile, the wheel diameter of the rear caster (27) is smaller than that of the middle caster (26) and the front caster (25). This makes it possible to place the footrest member (3) low, facilitating the boarding motion of the passenger. In addition, each of the front caster (25), the middle caster (26), and the rear caster (27) has a turning function. Therefore, the commercial device (1) can move not only straight and turning, but also lateral and spin, and can freely change direction and move even on a narrow floor surface S such as a bathroom. In addition, it is preferable that at least four of the six casters in total are provided with a locking mechanism (brake) that restricts the rotation of the casters. According to this, the commercial device (1) can stabilize the stationary state even on a floor surface S that is prone to slipping due to unevenness.

2. Detailed configuration and removal operation of the foot support (3)

Next, the detailed configuration of the foot mounting member (3) and the attachment/detachment operation to the base (2) will be described with reference to Figs. 3 to 6. The foot mounting member (3) is formed in a plate shape that covers the rear of the base (2). As a material and manufacturing method of the foot mounting member (3), an injection manufacturing method using ABS resin can be exemplified, but is not limited thereto. The width dimension in the left-right direction of the foot mounting member (3) is large at the front side and gradually decreases toward the rear side.

The entire left and right sides of the foot mounting member (3) have a protruding shape that protrudes upward. The front edge of the front side of the protruding shape of the foot mounting member (3) is bent downward. A U-shaped attachment/detachment groove (30) (see Fig. 3) that opens downward is formed on each of the left and right leading edges. The groove width of the attachment/detachment groove (30) is slightly larger than the diameter of the pipe frame (21). The left and right sets of attachment/detachment grooves (30) are attached/detachable at a position near the front of the middle portion (212) of the pipe frame (21). Parts of the left edge, right edge, and rear edge of the foot mounting member (3) are rounded and bent downward.

The foot mounting member (3) is formed to be elastically deformable, as shown in FIGS. 4 and 5. Specifically, when the user does not place his or her foot on the foot mounting member (3), the foot mounting member (3) has a shape as shown in FIG. 4. That is, the foot mounting member (3) has a slope that decreases from the central portion (31) in the left-right direction toward the left peripheral portion (32) and the right peripheral portion (33). The slope angle A1 at this time is preferably generally 10° or more. By optimizing the slope angle A1 when the user does not place his or her foot on the foot mounting member (3), even if a water droplet falls on the upper surface of the foot mounting member (3), the water droplet flows out of the device along the slope. Therefore, after use of the commercial device (1), moisture does not remain on the upper surface of the foot mounting member (3), and the growth of germs, etc. is suppressed.

In addition, the foot mounting member (3) takes the shape shown in Fig. 5 when the subject places the foot F. That is, the foot mounting member (3) is deformed so that the central portion (31) lowers due to the load applied from the placed foot F, and the incline becomes gentle. The incline angle A2 at this time is optional, but is preferably 3° or more. With an incline angle A2 of 3° or more, water droplets on the upper surface of the foot mounting member (3) automatically flow out of the device even when the subject is riding. Therefore, slipping of the subject's foot F is suppressed. On the other hand, if the incline angle A2 is excessive, the subject will feel discomfort on the soles of their feet, which is not preferable. In addition, the upper surface of the foot mounting member (3) does not need to be two strictly inclined planes, and may be a curved surface in which the incline angles (A1, A2) slightly change locally.

As shown in Fig. 3, on the lower surface of the foot mounting member (3), protruding stripes (34) that intersect in a grid pattern are installed. By appropriately designing the material and thickness of the foot mounting member (3), and the height, width, and arrangement pitch of the protruding stripes (34), sufficient mechanical strength, appropriate elastic strength, and inclination angles (A1, A2) of the foot mounting member (3) can be realized. In addition, the protruding stripes (34) do not have to be in a grid pattern, and may have, for example, a plurality of rectangular shapes arranged in layers or a plurality of parallel straight shapes.

In addition, as shown in FIGS. 3 to 5, a pair of left and right detachable parts (35) are installed at two locations on the lower surface of the foot support member (3). The pair of detachable parts (35) is attached and detached at a position near the rear of the middle part (212) of the pipe frame (21). As described above, each of the detachable parts (35) is formed of a pair of left and right gripping claws (36) that extend downward and are elastically deformable. The distance between the left and right gripping claws (36) is slightly smaller than the diameter of the pipe frame (21) at the lower end and larger than the diameter of the pipe frame (21) at the middle height.

The operator performs an installation operation to lower the foot mounting member (3) toward the pipe frame (21) of the base (2). At this time, the pipe frame (21) is engaged without resistance in the attachment/detachment groove (30) of the front edge of the foot mounting member (3). Meanwhile, the operator needs to apply a downward installation load to the two attachment/detachment portions (35). Due to this attachment load, one set of gripping jaws (36) elastically deforms and the gap between the lower ends widens. As a result, the pipe frame (21) is engaged to the middle height of one set of gripping jaws (36). Finally, the foot mounting member (3) is mounted and installed on the pipe frame (21), one set of front plate frames (23), and one set of rear plate frames (24).

During use of the market device (1), one set of the gripping jaws (36) returns to its original shape, the gap at the bottom becomes narrower, and the omission of the pipe frame (21) is controlled. Therefore, the foot mounting member (3) does not simply float during use. In addition, the gripping member performs a detachment operation to raise the foot mounting member (3) from the pipe frame (21). At this time, the gripping member needs to apply an upward detachment load to the two detachable parts (35) in addition to an upward load corresponding to the dead weight of the foot mounting member (3). However, the total load is not excessive and does not place an excessive burden on the gripping member. Due to this detachment load, one set of the gripping jaws (36) elastically deforms, the bottom part opens, the pipe frame (21) comes out from between the one set of gripping jaws (36), and the foot mounting member (3) is detached. In this way, the foot support member (3) can be attached to and detached from the base (2) without using tools. Therefore, various maintenance tasks, including cleaning of the commercial device (1), become easier.

In addition, in the installation state of the foot mounting member (3), a gap is created between the central side gripper (36) and the pipe frame (21). Therefore, when the subject places the foot F on the foot mounting member (3), the central side gripper (36) can approach the pipe frame (21), and the left peripheral part (32) and the right peripheral part (33) can be displaced outward. As a result, the central part (31) can be easily lowered, and the foot mounting member (3) can be easily elastically deformed from the shape of Fig. 4 to the shape of Fig. 5.

3. Multiple protrusions (37)

Next, a description will be given of a plurality of protrusions (37) installed on the upper surface of the foot mounting member (3) with reference to Fig. 6. The plurality of protrusions (37) are installed to prevent slipping of the feet F of the user being tested. It is preferable that the protrusions (37) have a shape that is long in the left-right direction. The first reason for this is that the user often sways in the front-back direction when using the testing device (1), and therefore, it is more important to prevent slipping of the feet F in the front-back direction than in the left-right direction. The second reason is the necessity of having a shape that does not impede water droplets flowing out in the left-right direction from the upper surface of the foot mounting member (3).

As a specific shape of the protrusion (37), a transverse ellipse or an annular rectangle can be adopted in plan view. An annular rectangle means a shape in which the four corners of a rectangle are replaced with quarter circles. The protrusion (37) exemplified in Fig. 6 has a shape that maximizes the quarter circles of an annular square, in other words, a shape similar to a track for track and field events. As for the dimensional specifications of the protrusion (37), height = 2 mm, horizontal dimension L1 = 15 mm, and vertical dimension L2 = 5 mm can be exemplified, but are not limited thereto.

In addition, the plurality of protrusions (37) are arranged regularly, and a staggered arrangement is shown in Fig. 6. However, the present invention is not limited thereto, and the plurality of protrusions (37) may be arranged in a grid pattern. It is preferable that the arrangement pitch P1 of the plurality of protrusions (37) in the left-right direction be larger than the arrangement pitch P2 in the front-back direction. In other words, by reducing the arrangement pitch P2 in the front-back direction and narrowing the gap, the effect of preventing the foot F from slipping in the front-back direction can be enhanced.

If the arrangement pitch (P1, P2) is set too small, the water droplets will not flow out but will remain in clumps due to surface tension, which is not desirable. In addition, if the arrangement pitch (P1, P2) is set too large, the anti-slip effect will decrease, which is not desirable. In the case of adopting the shape and dimension specifications of the protrusion (37) as a very suitable example, the arrangement pitch P1 in the left-right direction can be set to a range of 50 to 80 mm, and the arrangement pitch P2 in the front-back direction can be set to a range of 25 to 50 mm.

In addition, the plurality of protrusions (37) may be arranged not on the entire upper surface of the foot mounting member (3), but only on a part of the upper surface. For example, if the protrusions (37) are arranged in a foot-shaped area that is slightly larger than the foot F of the subject among the upper surfaces of the foot mounting member (3), the position for placing the foot F can be guided. In addition, the shapes of the plurality of protrusions (37) may be different. For example, the protrusions (37) near the central portion (31) may be formed low, and the protrusions (37) near the left peripheral portion (32) and the right peripheral portion (33) may be formed high, so that the upper envelope of the foot mounting member (3) can be made close to flat. In addition, the arrangement pitches (P1, P2) may be locally different.

4. Cover member (81) of driving unit (7)

Next, the cover member (81) installed on the driving part (7) will be described with reference to FIGS. 7 to 9. As described above, a linear actuator having a fixed part (71) and a movable part (72) is used as the driving part (7). Typically, a seal part made of synthetic rubber is assembled to the sliding part (73) where the fixed part (71) and the movable part (72) slide, thereby achieving a predetermined sealing performance. However, it is difficult to ensure sufficient sealing performance with this seal part alone for repeated or continuous use in a bathroom where moisture is present and liquid soap, etc. may splash. If water enters the sliding part (73), there is a risk of malfunction, deterioration, or other malfunctions of the driving part (7). Therefore, as shown in FIGS. 7 to 9, a cover member (81) is installed on the driving part (7) to prevent the sliding part (73) from getting wet.

A cylindrical bellows cover illustrated as a cover member (81) can be used. The lower end of the cover member (81) is connected to the upper end of the fixed member (71). Specifically, the lower end of the cover member (81) is fastened and fixed around the fixed member (71) using a resin fastening belt (82) (e.g., lnsulok (registered trademark)). Similarly, the upper end of the cover member (81) is fastened and fixed around the upper end of the movable member (72) using the fastening belt (82). According to this, when the movable member (72) is extended upward by the first and second extension operations of the driving member (7), the cover member (81) formed of the bellows cover is extended by the same stroke amount, thereby preventing moisture from entering the inside of the cover. For reference, the amount of stroke of the movable part (72) between the contracted state shown in Fig. 8 and the expanded state shown in Fig. 9 is approximately 90 mm.

In this way, the cover member (81) can prevent the sliding portion (73) from becoming wet. The cover member (81) can also prevent foreign substances such as liquid soap or dust from entering the sliding portion (73). In addition, the cover member (81) may be a member other than a corrugated box cover, for example, a cylindrical member made of synthetic rubber with excellent elasticity.

5. Direct-acting absorber (84) and its cover member (88)

Fig. 10 is a view showing the outer cover of the arm member (5) removed. As illustrated, a linear action absorber (84) is installed inside the outer cover of the arm member (5). The lower end of the fixed portion (85) of the linear action absorber (84) is supported by a pipe material constituting the arm member (5). The tip of the movable portion (86) of the linear action absorber (84) is connected to a link member (57) of a link mechanism. In other words, the movable portion (86) is connected to the support member (6) via the link mechanism. The linear action absorber (84) is normally maintained in contraction. The linear action absorber (84) operates when the support member (6) is driven by a device other than the driving portion (7), and limits the moving speed of the support member (6). The linear action absorber (84) is a type of elastic operating portion having a fixed portion (85) and a movable portion (86) that expands and contracts with respect to the fixed portion (85).

In addition, in the present embodiment, a configuration is adopted in which one driving unit (7) drives two parts (arm member (5) and support member (6)) via a link mechanism, and the degree of freedom remains in the movement of the support member (6). In addition, when the driving unit (7) contracts to support the seating movement of the user, there are cases in which the user or the support member applies force in the seating direction to the support member (6) (when driven by a device other than the driving unit (7). In this case, the moving speed of the support member (6) becomes faster than when it is normally driven by the driving unit (7). At this time, the direct-acting absorber (84) operates, that is, the movable unit (86) extends at a low speed below a specified speed, thereby limiting the moving speed of the support member (6) in the seating direction from becoming excessive. If the direct-acting absorber (84) is not installed, the moving speed of the support member (6) may be excessive, which may cause the subject to feel uneasy or cause the subject to slip and fall from the support member (6).

In the direct acting absorber (84), as in the driving unit (7), it is difficult to secure sufficient sealing performance with only the seal parts assembled to the sliding portions of the fixed portion (85) and the movable portion (86). Therefore, as shown in Fig. 10, a cover member (88) is installed on the direct acting absorber (84) to prevent wetting of the sliding portion. The shape, installation method, and function of the cover member (88) are the same as those of the cover member (81) of the driving unit (7), and therefore, a detailed description thereof is omitted. For reference, the operating stroke of the direct acting absorber (84) is smaller than that of the driving unit (7). Therefore, the cover member (88) may be shorter than the cover member (81) of the driving unit (7).

According to the commercial device (1) of the embodiment, water droplets flow out of the device along the slope from the central portion (31) of the foot mounting member (3) toward the left peripheral portion (32) and the right peripheral portion (33), so that moisture retention is suppressed, the growth of germs is suppressed, and good hygiene is maintained. In addition, since a plurality of anti-slip protrusions (37) are provided on the upper surface of the foot mounting member (3), slipping of the feet F of the user is suppressed even if moisture remains. In addition, since the covering members (81, 88) are provided, wetting of the sliding portion (73) of the driving portion (7) and the sliding portion of the direct action absorber (84) can be prevented, so that malfunction of the driving portion (7) or the direct action absorber (84) due to moisture does not occur. Therefore, the commercial device (1) is suitable for use in a bathroom or shower room where moisture is always present.

6. Modification and application of the embodiment

In addition, the commercial device (1) of the embodiment is not limited to use in a bathroom or shower room, and for example, when used in a restaurant, restroom, living room, etc., it is effective against water spilled from a sink or a beverage spilled by a customer. In addition, the foot mounting member (3) of the embodiment elastically deforms depending on whether the foot F is mounted or not, and the inclination angle (A1, A2) changes, but it may be a non-deforming foot mounting member that always has a constant inclination angle. In addition, the foot mounting member (3) is inclined toward the left and right from the center portion (31) in the left-right direction, but it may be shaped to be inclined toward the front and rear from the center portion in the front-back direction. In addition, one of the cover member (81) and the cover member (88) may be omitted. In addition to this, the embodiment is capable of various modifications and applications.
