Description

[Technical Field]

[0001] The present invention relates to a transport vehicle for transporting bathers and a bathing apparatus. [Background technology]

[0002] Patent Document 1 describes a folding wheelchair in which seat fixing portions on both sides of the seat can be fixed to the seat support frame in a front-upward tilted state via tilt adjustment bases that are angle-adjustable relative to the seat support frame, thereby preventing the hips from slipping off the seat. Specifically, to enable the seat to be fixed on the seat support frame in a front-upward tilted state at any angle θ from the horizontal state, a support bolt is threaded from below into a fixing nut fixed to the seat support frame, and the tip of the support bolt supports the tilt adjustment base. When the tip of the support bolt is extended high above the seat support frame, the tip of the support bolt supports the tilt adjustment base at that position, and when the tilt fixing bolt is then tightened with a nut threaded below it, the seat support frame, tilt adjustment base, and seat fixing portions are fixed, and the seat can be fixed in a front-upward tilted state at any angle θ from the horizontal state.

[0019] (Embodiment 1) The transport vehicle (first transport vehicle) of the first embodiment will be described with reference to FIGS. 1 to 8. As shown in FIG. 1, the directions of front, back, left, right, and up and down are those seen from the perspective of a bather seated on the transport vehicle 1. As shown in FIG. 1, the transport vehicle 1 comprises a carriage section 2 and a boarding section 3 detachably mounted on the carriage section 2, and the boarding section 3 is capable of rising and falling. The carriage section 2 has wheels 5 at four locations on a carriage frame 4, and is configured to be able to run on the floor surface. Two rails 6 are provided on the carriage frame 4 for detachably placing the boarding section 3. A carriage coupling section 7 is provided on the side of the carriage frame 4 for coupling the carriage section 2 to a bathtub 23 (see FIG. 8 described later), and the carriage coupling section 7 has rollers 7a for positioning the transport vehicle 1 relative to the bathtub 23 and hooks 7b for coupling and fixing the transport vehicle 1 to the bathtub 23.

[0020] The boarding section 3 has a backrest 8, a seat 9, a foot support 10, upper limb side fences 11, a lower back side fence 12, and a chair frame 13. The chair frame 13 is provided with a plurality of rollers 14, which allow the boarding section 3 to move on the rails 6 of the cart section 2. A back mat 15a, a seat mat 15b, and a leg mat 15c are laid on the backrest 8, the seat 9, and the foot support 10, respectively. The backrest 8 and the foot support 10 are rotatable relative to the seat 9, allowing the backrest 8, the seat 9, and the foot support 10 to be positioned substantially flat as shown in FIG. 2. Here, the boarding section 3 in the position shown in FIG. 1 is in a chair state, and the boarding section 3 in the position shown in FIG. 2 is in a stretcher state.

[0021] As shown in FIG. 2, the cart unit 2 is provided with foot-operated foot switches 16a and 16b and a pedal 17. The foot switches 16a and 16b lower and raise the boarding unit 3. The boarding unit 3 lowers while the foot switch 16a is pressed, and the descent stops when the foot switch 16a is released. Furthermore, if the boarding unit 3 reaches its lowest position while the foot switch 16a is pressed, the descent stops. The boarding unit 3 rises while the foot switch 16b is pressed, and the rise stops when the foot switch 16b is released. Furthermore, if the boarding unit 3 reaches its highest position while the foot switch 16b is pressed, the rise stops. The pedal 17 is connected to the hook 7b by a link piece (not shown). Pressing the pedal 17 disengages the hook 7b from the bathtub 23, thereby releasing the connection between the cart unit 2 and the bathtub 23.

[0022] 4, when the seat 9 is in a horizontal or substantially horizontal state (hereinafter referred to as the "substantially horizontal state"), an upper surface 9a1 of a front portion 9a of the seat 9 is configured to be higher than an upper surface 9b1 of a rear portion 9b of the seat 9, and a step 9c is formed at the boundary between the front portion 9a and the rear portion 9b of the seat 9. In the first embodiment, the seat 9 in the normal state is substantially horizontal, but the seat 9 may be slightly tilted or may not be in a substantially horizontal state.

[0023] As shown in FIG. 4, the seat 9 is fixed to the chair frame 13 using hinges 18 and is rotatable around the axis 18a of the hinge 18. As shown in FIG. 5, plunger holders 19 are provided on both the left and right sides of the underside of the front portion 9a of the seat 9, and index plungers 20 are attached to the plunger support portions 19. When the seat 9 is in its normal state, the tip of the index plunger 20 is in pressure contact with the chair frame 13, and when a force is applied to lift the front end 9f, which is the front end of the seat 9 in the normal state, upward, the front end 9f of the seat 9 can be rotated and moved upward. In other words, in the normal state, the seat 9 is not fixed, and the front end 9f of the seat 9 can be rotated upward.

[0024] As shown in FIG. 5 , holes 21 are provided on both the left and right sides of the chair frame 13, below the front portion 9a of the seat 9. When the front end 9f of the seat 9 moves upward as the seat 9 rotates, the tip of the index plunger 20 reaches the position of the hole 21. A rod (not shown) protrudes from the tip of the index plunger 20 and fits into the hole 21, locking the seat 9 and preventing it from rotating. At this time, as shown by the imaginary lines in FIG. 4 , the seat 9 is inclined at a predetermined angle from horizontal (predetermined inclination state), and this state is maintained. To release the locked state of the seat 9, the left and right index plungers 20 are pulled away from the holes 21 to remove the rods from the holes 21. In this way, the plunger holders 19, the index plungers 20, and the holes 21 provided in the chair frame 13 constitute a locking mechanism 22 that automatically locks the seat 9. The predetermined angle can be set to, for example, 5 degrees, but is not limited to 5 degrees. Alternatively, the angle may be set in multiple stages, such as 5 degrees or 10 degrees, so that it can be selected appropriately.

[0025] Next, a case where a bather who can maintain a seated position is allowed to take a bath using the transport vehicle 1 will be described. [Transfer, transport] First, as shown in FIG. 6, the boarding section 3 of the transport vehicle 1 is set in a chair position, and the foot support section 10 is folded at an intermediate position and stored in the space below the seat section 9 so that it does not get in the way when the bather is transferred, and then the bather is transferred to the transport vehicle 1. Here, when transferring the bather to the transport vehicle 1 from the left side of the transport vehicle 1, for example, the left upper limb side fence 11 and the left lower back side fence 12 are folded down as shown by the imaginary lines in FIG. 6. Once the bather is loaded onto the transport vehicle 1, the foot support section 10 is set in the position shown in FIG. 1, and the bather is then transported near the bathtub 23. As mentioned above, a step 9c is formed at the boundary between the front portion 9a and the rear portion 9b of the seat section 9, and this step 9c prevents the bather's buttocks from shifting forward and causing the body to slip off the seat section 9 during transport.

[0026] [Body washing, connection] Next, the position of the boarding section 3 is changed to the stretcher state, and the boarding section 3 is raised to the uppermost position (the state shown in Figure 7). In this state, the bather's body is washed. The boarding section 3 may be raised or lowered to any height that the boarding section 3 can assume to perform the washing operation. After the washing operation, the transport vehicle 1 is connected to the bathtub 23 along the long side as shown in Figure 8. Two rails 24 are provided inside the bathtub 23, and the distance between these two rails 24 is the same as the distance between the two rails 6 of the transport vehicle 1. The height of the two rails 24 inside the bathtub 23 is the same as the height of the two rails 6 when the boarding section 3 of the transport vehicle 1 is raised to the uppermost position.

[0027] [bathing] Next, the boarding section 3 is slid from the transport vehicle 1 toward the bathtub 23 and moved onto the rails 24 inside the bathtub 23, after which the bathtub 23 is raised. The bathtub 23 is filled with hot water, and the bather on the boarding section 3 can begin bathing by raising the bathtub 23 to a predetermined height. As the bathtub 23 rises, the buoyancy of the hot water in the bathtub 23 acts on the seat 9 and also on the bather's body, causing the front end 9f of the rotatable seat 9 to rotate upward. Once the seat 9 rotates a predetermined angle, it automatically locks into a predetermined inclined position, which it maintains. By raising the seat 9 to a predetermined inclined position, it is possible to prevent the bather's buttocks from shifting forward due to buoyancy or other factors, causing the body to slip off the seat 9. Furthermore, as the bathtub 23 rises, the seat 9 automatically reaches a predetermined inclined position, eliminating the need for a caregiver to operate it.

[0028] [Exit bath, transportation] When the bathing is finished, the bathtub 23 is lowered, the boarding section 3 is moved from the bathtub 23 onto the cart section 2 of the transport vehicle 1, and then the transport vehicle 1 and the bathtub 23 are disconnected. The bather's body is then wiped, and the boarding section 3 is placed in a chair position and the bather is transported to the original location. Here, the seat section 9 is maintained in a predetermined inclined state, which further prevents the bather's body from slipping off the seat section 9 during transport. Then, the seat section 9 is returned from the predetermined inclined state to its normal state, the foot support section 10 is stored in the space below the seat section 9, and the upper limb side fences 11 and the waist side fences 12 are retracted as necessary, and the bather is then transferred from the transport vehicle 1 to another wheelchair or the like to complete the bathing procedure.

[0029] In the above explanation, the bather is transferred onto the transport vehicle 1 in the state shown in Figure 6, but the bather may also be transferred onto the transport vehicle 1 in Figure 6 after an assistant has pulled up the front end 9f of the seat 9 to set the seat 9 to a predetermined inclination. In this case, it is possible to further prevent the bather's buttocks from shifting forward and sliding off the seat 9 during transport. Furthermore, in order to set the seat 9 to a predetermined inclination, the assistant only needs to pull up the front end 9f of the seat 9, making the procedure simple and quick.

[0030] Next, a case where a bather who cannot maintain a sitting position is allowed to take a bath using the transport vehicle 1 will be described. [Transfer, transport] First, as shown in Figure 2, the boarding section 3 of the transport vehicle 1 is set in the stretcher state, and then the bather is transferred onto the transport vehicle 1. For example, when transferring the bather onto the transport vehicle 1 from the left side of the transport vehicle 1, the left upper limb side fence 11 and the waist side fence 12 are folded down as shown by the imaginary lines in Figure 2. Then, once the bather is placed onto the transport vehicle 1, they are transported close to the bathtub 23. The transfer operation can be performed by raising and lowering the boarding section 3 to any height that the boarding section 3 can assume.

[0031] [Washing, connecting, bathing] For the bather's washing, connecting the transport vehicle 1 to the bathtub 23, and bathing, the same operations as those for the [washing, connecting] and [bathing] processes described for a bather who is able to assume a seated position can be performed.

[0032] [Exit bath, transportation] When the bathing is finished, the bathtub 23 is lowered, the boarding section 3 is moved from the bathtub 23 onto the carriage section 2 of the transport vehicle 1, and then the transport vehicle 1 and the bathtub 23 are disconnected. After that, the seat section 9 is returned to its normal position, the bather's body is wiped, and the bather is transported to the original location. Then, after the upper limb side fences 11 and the waist side fences 12 are retracted, the bather is transferred from the transport vehicle 1 to another transport vehicle, etc., and the bathing procedure is completed.

[0033] Although the entire seat 9 in the first transport vehicle 1 rotates, at least a portion of the seat 9 may rotate. That is, at least a portion of the seat 9 may be configured so that the front end of the seat 9 is rotatable upward in the normal state, and the remaining portion of the seat 9, excluding at least a portion, is fixed to the chair frame 13. A locking mechanism may be provided to automatically lock at least a portion of the seat 9 when at least a portion of the seat 9 rotates to a predetermined inclined position. At least a portion of the seat 9 may be, for example, cylindrical in shape so that it can be positioned between the left and right thighs of a bather sitting on the seat 9. This configuration allows at least a portion of the seat 9 to rotate easily even when the bather is seated on the seat 9, preventing the bather from slipping off the seat 9. Furthermore, during bathing, the buoyancy of the hot water in the bathtub 23 causes at least a portion of the seat 9 to rotate to a predetermined inclined position. The size and shape of at least a portion of the seat 9 are not limited to the above examples, as long as they can be safely positioned between the left and right thighs of a bather sitting on the seat 9 and can prevent the bather's body from slipping off the seat 9.

[0034] (Embodiment 2) The transport vehicle of the second embodiment (second transport vehicle) has a seat divided into two parts. The seat of the second transport vehicle will be described below with reference to FIG. 9. As shown in FIG. 9, the seat 25 is composed of a first seat part 25a disposed at the rear and a second seat part 25b disposed in front of the first seat part 25a. The first seat part 25a is fixed to the chair frame 13 and is in a substantially horizontal position. One end of a mounting frame 26 for the second seat part 25b is rotatably connected to a bearing 27 fixed to the chair frame 13, and the second seat part 25b is rotatable around a shaft 27a. One end of an angle adjustment lever 28 is rotatably connected to a connecting part 26a at the other end of the mounting frame 26. A protrusion 28a extending in the left-right direction is provided at the other end of the angle adjustment lever 28, and a handle 28b is provided at the middle position of the angle adjustment lever 28.

[0035] Plate-shaped angle adjustment lever receiver 29 is fixed to chair frame 13, and a roughly rectangular hole 29a is provided inside angle adjustment lever receiver 29, within which protrusion 28a of angle adjustment lever 28 is positioned. Hole 29a of angle adjustment lever receiver 29 has a recess 29b that slopes downward from rear to front at the front lower corner of the roughly rectangular hole 29a.

[0036] As shown in Figure 9, the projection 28a of the angle adjustment lever 28 fits into the recess 29b of the angle adjustment lever receiver 29, allowing the second seat portion 25b to maintain a state inclined at a predetermined angle relative to the horizontal (a predetermined inclined state). In the state shown in Figure 9, when the handle 28b is operated to disengage the projection 28a of the angle adjustment lever 28 from the recess 29b of the angle adjustment lever receiver 29, the second seat portion 25b returns to its normal state (a substantially horizontal state in this case, but not limited to a substantially horizontal state). At this time, the projection 28a of the angle adjustment lever 28 is positioned on the lower side of the hole 29a of the angle adjustment lever receiver 29 and behind the recess 29b. When the first seat 25a and the second seat 25b are in an approximately horizontal position, the upper surface 25b1 of the second seat 25b is configured to be higher than the upper surface 25a1 of the rear part of the first seat 25a, and similar to the seat 9 described using Figure 4, the bather's body can be prevented from slipping off the seat 25 during transport.

[0037] In the normal state, the front end 25f of the second seat portion 25b is not fixed, and when a force is applied to lift the front end 25f upward, the front end 25f of the second seat portion 25b can rotate and move upward. In other words, in the normal state, the front end 25f of the second seat portion 25b can freely rotate upward. When the front end 25f of the second seat portion 25b moves upward, the protrusion 28a of the angle adjustment lever 28 moves forward and fits into the recess 29b, automatically locking the second seat portion 25b. In this way, the angle adjustment lever 28 and the angle adjustment lever receiver 29 constitute a locking mechanism 30 that automatically locks the second seat portion 25b.

[0038] In the second transport vehicle, the attendant pulls up the front end 25f of the second seat 25b to set the second seat 25b to the desired inclination, and then the bather can be transferred to the transport vehicle. To set the second seat 25b to the desired inclination, the attendant simply pulls up the front end 25f of the second seat 25b, making the process simple and quick. If the bather's buttocks are resting on the first seat 25a and not on the second seat 25b at all, the front end 25f of the second seat 25b can be pulled up while the bather is still sitting on the seat 25. When the buoyancy of the water in the bathtub 23 causes the second seat 25b to rotate to the desired inclination, the locking mechanism 30 automatically locks the inclined position.

[0039] While the entire second seat 25b rotates in the second transport vehicle, at least a portion of the second seat 25b may rotate. That is, in the normal state, at least a portion of the second seat 25b is configured so that the front end can rotate upward, and the remaining portion of the second seat 25b, excluding at least a portion, is fixed to the chair frame 13. A locking mechanism may be provided that automatically locks at least a portion of the second seat 25b when at least a portion of the second seat 25b rotates to a predetermined inclined position. At least a portion of the second seat 25b may be, for example, cylindrical in shape and large enough to stand upright between the left and right thighs of a bather sitting on the seat 25. This configuration allows at least a portion of the second seat 25b to be easily rotated even when the bather is seated on the seat 25, preventing the bather from slipping off the seat 25. Furthermore, when bathing, at least a portion of second seat 25b rotates to a predetermined inclined state due to the buoyancy of the hot water in bathtub 23. The size and shape of at least a portion of second seat 25b are not limited to the above example, as long as it can be safely placed between the left and right thighs of a bather sitting on seat 25 and can prevent the bather's body from slipping off seat 25.

[0040] In addition, in embodiments 1 and 2, a transport vehicle for bathing in a lying position has been described, but the present invention can also be applied to a transport vehicle for bathing in a sitting position or a lift bathing, in which the chair-like boarding section is separated from the cart section and inserted into the bathtub.
