Similar to the first arm member 6 , pads 71 are respectively provided on the lower surface of the front end portion of the second arm member 7 , and the pads 71 are in contact with the upper surface of the second frame portion 32 . Furthermore, as shown in FIG. 5 , in the initial state, the second arm member 7 is disposed above the first arm member 6 and is disposed so that parts of the first and second arm members 6 and 7 overlap when viewed from below. Therefore, the vertical position of each arm member 6 and 7 with respect to each shaft member 53 and 54 is determined so that this arrangement may be achieved.

Next, the connecting member 8 will be described. The connecting member 8 is a long rod-shaped member having a first end 81 and a second end 82 at both ends. As shown in Figure 6, the first end 81 of the connecting member 8 is at The first arm member 6 is rotatably connected slightly forward of the first shaft member 53 . On the other hand, the second end portion 82 of the connecting member 8 is rotatably connected to the rear side of the second shaft member 54 in the second arm member 7 . In the initial position shown in FIG. 5 , the second end portion 82 is disposed on the second frame portion 32 side of the second shaft member 54 . Furthermore, the second end portion 82 of the connecting member 8 is detachably connected to the second arm member 7 .

The adjustment member 85 is formed by a screw, and by rotating the adjustment member 85 forward and backward, the gap distance between the first connection part 83 and the second connection part 84 can be adjusted. As a result, the length of the connecting member 8 can be adjusted. Furthermore, in the connecting member shown in FIGS. 5 to 7 , an outer cover 88 for detachably covering the adjustment member 85 is attached to the connecting member 8 , and FIG. 8 shows a state in which the outer cover 88 is removed.

<3-2. Action of arm mechanism>

Next, the operation of the arm mechanism configured as above will be described. When the handle 631 of the first arm member 6 is pulled from the initial state in FIG. 5 , the first arm member 6 moves with the first axis member 53 as the center. Turn around. Thereby, the first end portion 81 of the connecting member 8 is pulled to the first frame portion 31 side, and along with this, the second end portion 82 of the connecting member 8 pinches the second shaft member 54 from the second frame portion 32 side. Move toward the first frame portion 31 side. As a result, the second end portion 82 pulls the second arm member 7, so that the second arm member 7 rotates toward the second frame portion 32 side as shown in FIG. 7 . Therefore, as the first arm member 6 rotates, the second arm member 7 also rotates. As shown in FIG. 6 , in the installed state, the first arm member 6 is arranged on the first frame part 31 and the second arm member 7 is arranged. on the second frame part 32. At this time, the two pads 61 and 62 of the first arm member 6 are arranged on the first frame part 31, and the pad 71 of the second arm member 7 is also arranged on the second frame part 32. Therefore, the two arm members 6 and 7 Set stably on the frame.

Furthermore, in the installed state, the first arm member 6 is arranged orthogonally to the rail body 51 and is regulated so as not to rotate further.

In addition, in the state of FIG. 6 , the pads 61 , 62 , and 71 of the arm members 6 and 7 are arranged on the frame. For example, when the distance between the first frame part 31 and the second frame part 32 changes, even if The first arm member 6 is installed orthogonally to the rail body 51 , and the pad 71 of the second arm member 7 may not be installed on the second frame part 32 .

Therefore, in this embodiment, as mentioned above, the length of the connecting member 8 can be changed by adjusting the member 85 . For example, as shown in FIG. 8(b) , the adjustment member 85 is rotated to lengthen the gap distance between the first connection part 83 and the second connection part 84 compared to the case in FIG. 8(a) , that is, the adjustment member 85 is rotated. When the length of the connecting member 8 becomes longer, when the first arm member 6 is rotated, the distance over which the second end 82 of the connecting member 8 pulls the second arm member 7 becomes shorter. Therefore, the rotation angle of the second arm member 7 becomes smaller. In the installed state, the gap between the pads 61 and 71 at the front ends of the first arm member 6 and the second arm member 7 is The distance becomes shorter. Therefore, as shown in FIG. 8( b ), even in the bathtub 3 in which the distance between the first and second frame parts 31 and 32 is shorter than that in FIG. 8( a ), the two arm members 6 and 7 can be appropriately provided. Furthermore, for the long bathtub 3 between the first and second frame parts 31 and 32, the gap distance between the two connecting parts 83 and 84 can be shortened by the adjusting member 85.

<4. How to use the bathing auxiliary system>

Next, the method of using the bathing auxiliary system configured as above will also be described with reference to Figures 9 to 12 . First, as shown in FIG. 4 , the cover member 42 of the support base 4 is opened, and the track unit 5 is rotated and placed on the frame. At this time, the handle 631 of the first arm member 6 is pulled, so that the two arm members 6 and 7 are rotated and arranged on the first frame part 31 and the second frame part 32 respectively. When the pads 61 and 71 at the front ends of the respective arm members 6 and 7 are not arranged on the frame in the installed state, the adjusting member 85 is adjusted as described above, thereby adjusting the length of the connecting member 8 .

Hereinafter, the method of adjusting the length of the connecting member 8 will be described. First, regardless of the length between the first and second frame parts 31 and 32, when the first arm member 6 is perpendicular to the track body (when the rotation is completed), the two pads 61 and 62 are arranged on the first arm member 6. The position of the track body 51 is adjusted in advance on the frame portion 31 . Next, the two arm members 6 and 7 are rotated into the installation state, and the two pads 61 and 62 of the first arm member 6 are arranged on the first frame part 31. At this time, for example, as shown in FIG. 9 , when the pad 71 of the second arm member 7 is located further outside the second frame portion 32 , the length of the connecting member 8 must be increased. Therefore, first, as shown in FIG. 10 , the second end portion 82 of the connecting member 8 is detached from the second arm member 7 . In this state, the second arm member 7 can rotate without regulation, so the user adjusts the rotation angle so that the pad 71 of the second arm member 7 is arranged on the second frame portion 32 .

Furthermore, when the pad 71 of the second arm member 7 is arranged on the second frame part 32, the length of the connecting member 8 is adjusted by the adjusting member 85. That is, the length of the connecting member 8 is increased until the second end 82 of the connecting member 8 can be fixed to the second arm member 7 . When the length adjustment is completed, as shown in FIG. 8(b) , the second end 82 is fixed to the second arm member 7 . Therefore, in the installed state, since the pads 61 and 71 of the two arm members 6 and 7 are arranged on the frame, even if the rotation from the initial state to the installed state is repeated, in the installed state, the two arm members 6 and 7 The pads 61, 62, and 71 must be arranged on the frame.

Next, the trolley 2 is moved so that the end of the rail member 24 of the transfer device 10 is adjacent to the end of the rail body 51, and the two are connected by a locking mechanism (not shown). Then, as shown in FIG. 11 , the rail member 24 is unlocked, and the housing 121 is slid and moved toward the rail body 51 . In this way, the housing 121 moves toward the bathtub 3 together with the chair 11 . At this time, sliding the sliding part 118a of the foot bracket 118 can move the footrest part 118b forward. Thereby, the person being assisted can straighten the foot and place it on the footrest part 118b. When the chair 11 is located above the internal space of the bathtub 3, the movement of the casing 121 is stopped, and the casing 121 is fixed on the track body 51 through the locking mechanism.

Then, as shown in FIG. 12 , the electric motor in the housing 121 is driven to lower the chair 11 . Thereby, the person being assisted sitting on the chair 11 can immerse himself in the hot water of the bathtub 3 for bathing. At this time, first move the trolley 2 away from the bathtub to facilitate bathing assistance. Thereafter, when the bathing is completed, the electric motor is driven to raise the chair 11 . Then, the electric motor is stopped when the chair 11 is located higher than the frame. Then, the trolley 2 is moved so that the rail member 24 is adjacent to the rail body 51 , and the housing 121 is slid and moved toward the rail member 24 . In this way, when the housing 121 is disposed on the track member 24, the housing 121 is fixed on the track member 24 through the locking mechanism. Afterwards, as long as The transfer device 10 can be moved from the bathtub 3 by releasing the fixation between the track member 24 and the track body 51 .

The first arm member 6 and the second arm member 7 are each rotatably connected to the rail body 51 , and the two arm members 6 and 7 are connected via the connecting member 8 . Therefore, by rotating the first arm member 6 , the second arm member 7 is rotated via the connecting member 8 . In other words, the first arm member 6 is rotated by rotating the second arm member 7 . Therefore, both arm members 6 and 7 can be rotated and arranged on the frame with one operation.

In addition, since the length of the connecting member 8 is adjustable, for example, when the length of the connecting member 8 is long, the distance that the connecting member 8 pulls the second arm member 7 when the first arm member 6 rotates is shortened. As a result, the rotation angle of the second arm member 7 becomes smaller, and the distance between the two arm members 6 and 7 becomes shorter. Therefore, even in the bathtub 3 in which the distance between the first frame part 31 and the second frame part 32 is short, both arm members 6 and 7 can be reliably installed. Thereby, the track unit 5 can be stably arranged on the frame, and the heavy chair unit 1 and the person being assisted can be stably supported.

<6.Example of changes>

As mentioned above, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the gist of the invention. Modification examples will be described below. However, the following modifications can be combined appropriately.

<6-1>

In the above embodiment, the first arm member 6 is provided in the first frame part 31, and the second arm member 7 is Although it is provided in the 2nd frame part 32, it can also be done in reverse. That is, the first arm member 6 may be connected to the second frame part 32 side of the rail body 51 , and the second arm member 7 may be connected to the first frame part 31 side of the rail body 51 . Thereby, the first arm member 6 can be provided in the second frame portion 32 and the second arm member 7 can be provided in the first frame portion 31 .

<6-2>

The method of adjusting the length of the connecting member is not particularly limited, and various structures can be applied as long as the length can be expanded or contracted. For example, the connecting member may be constituted by two nested rod-shaped members, or the two members may be connected and fixed using a pin or the like.

<6-3>

The track unit 5 of the present invention only needs to be provided with at least a track body 51 and an arm mechanism, and other specific structures can be appropriately changed. In addition, the structure of the support base 4 is not particularly limited as long as it can at least support the track unit 5 . Furthermore, the track unit 5 may be supported by a structure other than the support platform.

<6-4>

The structure of the transfer device 10 is not particularly limited. It suffices as long as it is a chair unit 1 that can at least slide along the track unit 5 and has a liftable chair 11 . Therefore, the chair unit 1 and the transfer unit 2 can be variously modified.

<6-5>

In addition, in the above embodiment, the rail body 51 is connected to the third frame part 33 of the bathtub 3. For example, the length of the third frame part 33 in the front-rear direction is longer, or as shown in Figure 13, the slope of the inner wall 35 from the third frame part 33 to the bottom surface of the bathtub 3 is gentle, and the inner wall surface 35 When the length in the front-to-back direction is long, when the chair 11 is lowered into the bathtub 3, the chair 11 may interfere with the third frame part 33 or the inner wall, and the chair 11 may not be able to be lowered.

Therefore, the track unit 5 can be configured as follows. As shown in FIG. 14 , plate-shaped fixing members 91 extending in the front-rear direction are mounted on the lower surfaces of both ends of the track body 51 . A plurality of through holes 911 arranged at specific intervals in the front and rear direction are formed on the upper end of the left and right side surfaces of the fixing member 91 .

Furthermore, an L-shaped adjusting member 92 for fixing each leg portion 41a of the support stand 4 to each fixing member 91 is provided. The adjustment member 92 has a first portion 921 extending in the up-down direction, and a second portion 922 extending forward from the upper end of the first portion 921, and is composed of an L-shaped plate. Furthermore, the lower end of the first portion 921 of the adjustment member 92 is rotatably connected to the upper end of the leg 41a. On the other hand, a plurality of through holes 923 arranged in the front-rear direction are formed in the second portion 922 of the adjustment member 92 . Furthermore, the through holes 923 of one or more adjustment members 92 are aligned with the through holes 911 of the fixing member 91 and fixed by bolts, screws, etc. (not shown). Therefore, by changing the positions where the two are fixed, the track body 51 can be fixed at different positions in the front-rear direction relative to the support base 4 .

For example, when there is a risk that the chair 11 cannot be lowered as described above, the through hole 923 on the front side of the adjustment member 92 and the through hole 911 on the rear side of the fixing member 91 are fixed with bolts. Thereby, as shown in FIG. 15 , since the rail body 51 is fixed in front with respect to the support base 4, Therefore, the chair 11 can be lowered without interfering with the third frame portion 33 or the inner wall surface 35 . In this way, the adjusting member 92 and the fixing member 91 can appropriately change the fixing position according to the shape of the third frame part 33 or the inner wall surface 35 of the bathtub 3 .

Furthermore, the method of changing the fixed position of the support platform 4 and the track unit 5 in the front-rear direction is not limited to the above-mentioned structure, and other structures are also possible. For example, a plurality of through holes may be provided on the bottom surface of the track body 51 to connect the adjusting member 92 without passing through the fixing member 91 .
