Plays. Further, the upper portion of the movable cover 450 is curved and enters between the two rows of first guides, and the curved portion serves as a head-mounted portion 453 of the person being assisted.

  Hereinafter, the structure of the movable cover 450 will be described in more detail with reference to FIG.

  The movable cover 450 is made of a synthetic resin such as ABS (acrylonitrile / butadiene / styrene resin) or PP (polypropylene), for example, and includes a main cover 451, side covers 452 provided on both sides of the main cover 451, A head mounting portion 453 provided on the upper portion of the cover 451. The main cover 451 has a rectangular shape, and a cushion (not shown) made of an elastic body with an appropriate thickness is attached to the surface of the person being assisted. When the seat 50 is in the upper limit position, the wire is used. In addition to covering the front surface of the winding / feeding-out portion 335 and covering the front surface of the wire winding / feeding-out portion 335 as the sheet 50 descends, the wire 100 fed out therefrom is partially covered.

  The holder 452 of the movable cover 450 is curved along the outer peripheral surface of the first guide of the multistage guide 40, and includes a C-shaped slider 454 at the upper end of the side cover 452. The slider 454 is made of a metal such as stainless steel (SUS), and is slidably fitted to the outer peripheral surface of the first guide 410. The slider 454 is movable when the movable cover 450 is lowered as the seat 50 is lowered. The cover 450 is guided along the first guide 410 of the multistage guide 40.

  The lower end of the movable cover 450 is attached to the first bridging plate 425 provided in the second guide 420 by an appropriate fastener such as a screw so that the movable cover 450 also descends as the second guide 420 is lowered. It has become. Accordingly, the first bridging plate 425 serves as a limiting unit that limits the amount of movement of the movable cover 450 in the vertical direction.

  In the movable cover 450, the upper portion of the movable cover 450 is the wire of the lifting device 30 in a state where the second guide 420 is completely extended from the first guide 410, that is, in the position where the second bridging plate is lowered most. It has a height sufficient to cover the take-up / feed-out part 335.

  The head mounting portion 453 of the movable cover 450 is formed to be curved so that the upper end of the main cover 451 enters the space between the first guides so that the back head of the person being assisted can be mounted on this portion. It has become.

  Further, the lower end of the main cover 451 is partially cut away to form a wire escape portion 451a. This portion prevents interference between the wire 100 and the movable cover 450 when the seat 50 is raised and lowered, thereby smoothing the seat 50. It is designed not to hinder lifting.

  On the other hand, the backrest portion 540 of the seat 50 covers the exposed portion of the wire 100 that cannot be covered by the movable cover 450 as the seat 50 descends. That is, when the seat 50 reaches the lower limit position, the upper end of the backrest 540 is positioned in the vicinity of the lower end of the movable cover 540 so as to cover most of the wire 100 from the front. In the case of this embodiment, the backrest 540 constitutes a fixed cover, and the movable cover constitutes a slide cover.

  With the above configuration, when the seat 50 is at the upper limit position, the movable cover 450 covers the front surface of the wire winding / unwinding portion 335 of the lifting device 30. Accordingly, the body of the person being assisted does not touch the wire take-up / feed-out portion 335 in this state. Further, since the wire 100 that is fed when the seat is lowered covers the movable cover 450 and the backrest 540 in cooperation, the body of the person being assisted does not touch the wire 100 even when the seat is raised or lowered.

  The wire escape portion 451a may have any shape as long as the wire 100 and the movable cover 450 do not interfere with each other and the wire 100 does not touch the person being assisted, and is formed as a notch in the main cover 451. Instead, it may be formed by a dent or the like.

  Next, the seat 50 with the backrest will be described. As shown in FIG. 1, the seat 50 with the backrest is made up of a sheet frame 510 formed by bending a pipe made of stainless steel having a round cross section into a sheet shape, and a pipe having a round cross section. An armrest 520 provided on the seat frame 510, a seat surface 530 attached to the seat frame 510 and a seat back portion 540 attached to the seat frame 510. The seat 50 is firmly fixed to the multistage guide 40 by connecting a part of the seat frame 510 to the fourth guide 440 of the multistage guide 40 and the connecting portion 446 with an appropriate fastener.

  Note that the height of the backrest 540 is equal to the height of the upper end of the multistage guide 40 at the upper limit position of the seating surface 530. More specifically, the height of the backrest 540 is, for example, about 200 mm to 400 mm, preferably about 350 mm, and the upper end of the backrest 540 is below the shoulder rib of the person being assisted while sitting on the seat 50. It is supposed to be located. In addition, if it is this height, it can be said that the backrest part 540 is not too high, it is easy to raise a caregiver's leg | foot, and it can be said that it is high enough to support the upper body of a caregiver without being too low.

  Then, the actual usage method of the bathing assistance apparatus 1 concerning this embodiment is demonstrated. First, as shown in FIG. 4, the bathing assistance apparatus 1 is placed on one side edge of the rim of the bathtub. Then, the width of the side frame 220 is adjusted until the holding plate 230 provided on the side frame 220 of the support frame 20 hits the inner wall side surface of the bathtub. After the side frame 220 is positioned at an appropriate position in the width direction, the side frame 220 and the main frame 210 are fixed by fastening screws (not shown). In this way, the bathing assistance device 1 can be easily attached to the rim of the bathtub.

  As described above, since the upper end portion of the multistage guide 40 is substantially the same height as the upper end portion of the backrest portion 540, the position of the center of gravity of the bathing assistance device itself is lowered, and the bathing described in Patent Document 2 is performed. Compared with the assistance device, the device itself is less likely to fall behind the bathtub.

  Next, the person being assisted is seated on the seat 50. At this time, the engagement between the cam ring 315 and the stopper is released by grasping the rotation lever 329 provided in the lifting device 30 of the bathing assistance device 1. As a result, the seat 50 can be rotated horizontally within a certain angular range, and the seat 50 is rotated to about 90 degrees with respect to the initial rotational position over the side rim of the bathtub. At this time, the rotation lever 329 is released, the stopper and the cam ring 315 are engaged, and the sheet 50 is fixed at a position where the sheet 50 is rotated 90 degrees.

  Then, the person being assisted is placed on the sheet 50 of the bathing assistance apparatus 1. Thereby, the person being assisted can sit on the seat 50 without straddling the rim of the bathtub. In addition, since the height of the upper end portion of the multistage guide 40 is approximately the same as the height of the backrest portion 540, when the caregiver is sitting on the seat 50, the caregiver holds the shoulder of the caregiver. Since the person being assisted can be seated on the seat 50 while supporting the head, it is easy to assist. Further, since the height of the movable cover 450 is approximately the same as the height of the backrest 540, it does not interfere with assistance.

  Here, the rotation angle of the sheet 50 may be 90 degrees or less, for example, 45 degrees. The bathing assistance device 1 limited to such a rotation angle is particularly suitable for use when the bathroom is narrow and it is difficult to assist the faucet attached to the bathroom wall or the wall when the seat 50 is turned 90 degrees. Yes.

  Subsequently, the rotation lever 329 is grasped, and the engagement between the cam ring 315 and the stopper is released again, the seat 50 can be rotated, and the person being assisted is moved to the upper side in the bathtub. At this time, the height of the upper end portion of the multi-stage guide 40 is suppressed to the height of the backrest portion of the seat 50, so that the assistant can hold the shoulder of the person being assisted and the head and neck while the seat 50 is moving. It is possible to easily rotate the seat 50 while supporting. In addition, since the height of the multi-stage guide 40 is approximately the same as the backrest 540 of the seat 50 and the height of the movable cover 450 is also approximately the same as the height of the backrest 540, When lifting and straddling the rim, it is possible to lift the foot while slightly lowering the upper body of the person being assisted, and the troublesome lifting operation of the foot can be easily performed.

  Subsequently, when the sheet 50 reaches the upper part of the bathtub, the rotation lever 329 is released and the stopper and the cam ring 315 are engaged again. Thereby, the sheet 50 is fixed at an appropriate position above the bathtub.

  Subsequently, as shown in FIG. 5, the sheet 50 is lowered to the bottom of the bathtub. At the time of lowering, the lowering button of the switch box provided in the control device that controls the bathing assistance device 1 is pushed. Thus, the motor 323 is driven using the electric power of the battery provided in the bathing assistance device 1, and the wire 100 wound around the drum 350 is fed out from the lifting device 30 via the pulley 370 (see FIG. 2). Is lowered. In this lowering, the multi-stage guide 40 is a telescopic type multi-stage guide, and the two multi-stage guides have a bridge structure, so that the seat 50 can be lowered smoothly, and the person being assisted Allows comfortable bathing.

  As the seat 50 is lowered, the second guide 420 of the multistage guide 40 is also lowered. And the movable cover 450 fixed to the 1st bridge | crosslinking board 425 of the 2nd guide 420 also descend | falls with this. Since the C-ring type slider 454 is provided at the upper end of the holder of the movable cover 450, the slider 454 slides along the first guide 410, and the movable cover 450 is smoothly lowered.

  In this process, the wire 100 is paid out from the wire take-up / feed-out unit 335. The wire take-up / feed-out unit 335 and the drawn-out wire 100 are covered with the movable cover 450, so that the person being assisted is attached to the wire 100. There is no touch.

  In this way, when the second guide 420 descends while sliding with respect to the first guide 410, the movable cover 450 also descends together with the second guide 420. Further, since the backrest 540 of the seat 50 is also fixed to the fourth guide 440, the seat 50 descends together with the fourth guide 440. Since the wire escape portion 451a is formed in the lower portion of the main cover 451 of the movable cover 450, the wire 100 is prevented from interfering with the movable cover 450 when the seat 50 is lowered, and the seat 50 is smoothly lowered. Is not disturbed.

  The movable cover 450 and the backrest 540 are considerably covered with the wire 100 fed out from the lifting device 30 while being relatively displaced from each other. That is, the movable cover 450 and the backrest part 540 cooperate to cover the wire winding / feeding part 335 from the lifting device 30 and the wire 100 fed from the winding / feeding part 335 as a whole. .

  Even if the movable cover 450 is completely lowered along the first guide 410, the wire take-up / feed-out portion 335 is still covered with the movable cover 450, so that the body of the person being assisted is taken up by the wire take-up / The feeding portion 335 is not touched.

  For this reason, it is assumed that the body of the person being assisted does not touch the wire 100 when the seat 50 is lowered, and the person assisted places the back of the head on the head rest 453 of the movable cover 450 with the seat 50 reaching the lower limit position. However, it is possible to have a comfortable bathing without the caregiver's hair getting caught in the wire take-up / feeding-out part 335.

  Moreover, since there is the head mounting part 453 in the form which entered between the multistage guides 40, the position of the head at the time of bathing can be made back from the multistage guide front surface (tub side surface). Therefore, the bathing space becomes wider and the posture during bathing becomes easier, so it is convenient.

  Since the wire 100 is strong enough to support the weight of the person being assisted and the motor 323 is decelerated via the worm gear, the seat 50 can be raised and lowered slowly and comfortably. it can. Moreover, since a complicated structure such as a clutch is not required by using the worm gear, the number of parts of the lifting device 30 can be reduced.

  When the sheet 50 reaches the bottom of the bathtub, the wire 100 is bent, and a limit switch (not shown) detects this bending and stops the feeding of the wire 100 by the motor 323.

  In this way, after the seat 50 reaches the bottom of the bathtub and bathing of the person being assisted is completed, the lift button of the switch box connected to the control device is pushed again to raise the seat 50.

  Even when the caregiver keeps the back of the head on the head rest portion 453 when the seat is raised, the movable cover 450 covers the wire take-up / feed-out portion 335. There is no getting involved.

  When the seat 50 is raised, the second guide 420 is accommodated in the first guide 410 and the fourth guide 440 is accommodated in the first guide 410 via the third guide 430 and the second guide 420. Is done. Along with this, the movable cover 450 and the backrest portion 540 of the seat 50 that entirely cover the wires 100 fed out from the lifting device 30 while being displaced from each other overlap with each other as the seat 50 rises. When the sheet 50 reaches the upper limit position, the movable cover 450 and the backrest portion 540 of the sheet 50 overlap with each other, and the front surface of the wire take-up / feed-out portion 335 with the movable cover 450 and the backrest portion 540 overlapped with each other. It comes to cover. Since the movable cover 450 and the backrest 540 are thus divided to cover the exposed wire portion, the movable cover 450 can be reduced in size, and the movable cover 450 is disposed above the lifting device 30. The sheet 50 can be raised to the upper limit position without protruding.

  In addition, since the wire escape portion 451a is formed in the main cover 451 of the movable cover 450, the wire 100 does not interfere with the movable cover 450 when the seat 50 is raised, and the smooth rise of the seat 50 is not hindered.

  In this way, the seat 50 is raised again to the uppermost position, and the seat 55 is stopped at the upper limit position by the detection of the limit switch, and then the caregiver holds the shoulder of the person being assisted and supports the neck and head while being supported. Tilt the upper part of the caregiver back slightly and lift the person's leg. Then, the rotary lever 329 is gripped, the engagement between the cam ring 315 of the lifting device 30 and the stopper is released, and the seat surface is rotated. At this time, the upper end portion of the multi-stage guide 40 has a height equivalent to the height of the backrest portion 540 of the seating surface, and the upper side of the backrest portion can be secured as an assistance space. It can be tilted back, which makes it easier for the caregiver to lift the person's foot and allows the rim of the bathtub to be easily straddled. In this way, when the seat 50 is rotated and the seat surface 530 exceeds the rim, the rotation lever 329 is released, and the cam ring 315 and the stopper are engaged again to fix the seat 50. At this point, the person being assisted is taken out of the bathtub, and the person being assisted is finished bathing. Thereby, the transferability of the person being assisted after bathing can also be improved.

  In this way, the person being assisted does not touch the wire 100, and the hair is not caught in the wire take-up / feed-out part 335, so that a comfortable bathing can be performed with the back of the head placed on the head-mounting part 453 of the movable cover 450. I can enjoy it.

  In addition, you may shape | mold so that the movable cover demonstrated above may be provided with a hollow structure with resin of ABS or PP instead of providing a cushioning material. A stainless steel plate material may be provided with a cushion material. Also, instead of fixing the movable cover 450 to the first bridging plate 425, the C-shaped slider 454 engages with a stopper provided at the lower end of the first guide 410 to determine the lower limit position of the movable cover. Anyway.
