(Embodiment)
FIG. 1 is a perspective view showing a state in which a seating member is lowered in the lifting device 1 according to the embodiment of the present invention. FIG. 2 is a perspective view showing a state in which the seat member is raised in the lifting device 1 of FIG. Drawing 3 is a mimetic diagram showing signs that the seat member of raising and lowering device 1 installed in the bathtub goes up and down. FIG. 4 is a schematic diagram illustrating a connection structure between the seat member and the lifting guide member. Hereinafter, the configuration of the lifting device 1 will be described with reference to FIGS.

  The lifting device 1 includes a seating member (also corresponding to a lifting member) 11, a link mechanism 12, a lifting guide member 13, a cable guide portion 14, and a driving device 15.

  The seat member 11 is a member on which the bather sits. The seat member 11 includes a base plate (corresponding to the base) 21, a seating portion 22, a first handle 23, a second handle 24, and a connection member 25. In addition, a space is provided between the end of the first handle 23 and the end of the second handle 24 on the side opposite to the end connected to the connecting member 25, and bathing is performed from this space portion. A person can sit on the seat member 11.

  The base plate 21 is a base portion that supports the seating portion 22, the first handle 23, the second handle 24, and the connection member 25. The base plate 21 is connected to the link mechanism 12 and guided by the lifting guide member 13 to move up and down. The base plate 21 is connected to the cable 54 (see FIG. 3) and is driven by the driving device 15.

  The seating part 22 is a part where a bather sits. The seat portion 22 is fixed to the base plate 21 so as to be rotatable. The direction of the body of the bather seated on the sitting member 11 can be changed by the rotation of the seating portion 22. The upper surface of the seating portion 22 may be subjected to anti-slip processing. The seat 22 has a thigh slip prevention portion 28 and a buttocks slip prevention portion 29. The thigh slip prevention portion 28 and the buttocks slip prevention portion 29 prevent the bather sitting on the seat portion 22 from shifting forward and backward from the seating position. In addition, although the seating part is rotatably provided as a separate body, it may be integral with the base plate 21 and may not rotate.

  The first handle 23 and the second handle 24 can be put on by a bather seated on the seat. The first handle 23 is fixed to the base plate 21 so as to be located on the left side of the bather seated on the seating portion 22 with the bathtub 80 in which the elevating device 1 is installed as the back. Between the 1st handle 23 and the seating part 22, the space | interval which can insert the leg of the bather who sat on the seating part 22 is provided. The first handle 23 is arranged higher than the second handle 24. In the following description, the left and right are defined with reference to the direction of the bather seated on the seat portion 22 with the bathtub 80 in the back.

  The second handle 24 is fixed to the base plate 21 so as to be located to the right of the bather seated on the seat portion 22 with the bathtub 80 in the back. The second handle 24 can lean against the back when the bather sits in the seating section 22 in a different direction.

  The first handle 23 and the second handle 24 are fixed to the base plate 21 by a support 27. The support column 27 is disposed behind the bather seated on the seat portion 22. Thereby, when a bather changes direction in the direction of the 1st handle 23, it can prevent a leg | foot from getting caught in the support | pillar 27. FIG. In addition, the support | pillar 27 of the 1st handle 23 and the 2nd handle 24 is not restricted to one, The support | pillar 27 may be provided in each of the 1st handle 23 and the 2nd handle 24. Alternatively, the first handle 23 may be disposed on the right and the second handle 24 may be disposed on the left. In this case, the direction of changing the body direction when the bather sitting on the seating portion 22 with the bathtub 80 in the back is the direction of the first handle 23. When the bather sits in a position so that the first handle 23 is in front, the bather holds the first handle 23 with both hands in the front so that the bather is in a stable state. can do. Further, since the second handle 24 can function as a backrest, even when the bather falls to the back side, the bather is prevented from falling into the water. That is, the bather is surrounded by the first handle 23, the second handle 24, and the connection member 25, and further, on the opening side of the first handle 23 and the second handle 24. Since the elevating guide member 13 exists, the bather is surrounded on all sides, so that the bather is prevented from detaching from the base plate 21 and immersing in the water.

  The connecting member 25 connects the first handle 23 and the second handle 24, and when the bather sits on the seat portion 22 with the bathtub 80 in the back, the connecting member 25 falls to the bathtub 80. It will also prevent. Furthermore, since there is no support | pillar directly connected to the 1st handle 23, the position of a bather's leg can also be freely located according to a physical condition etc. The first handle 23 extends horizontally to one side of the seat member 11, and a bather seated on the seat member 11 along the direction in which the first handle 23 extends is used by the bather. There is an open space between the end of the first handle 23 and the seat member 11 so that the bather's leg does not hit anything when the body is rotated so that 23 is in front. Is provided.

  The link mechanism 12 is a mechanism that regulates the movement path and posture of the seat member 11 when the seat member 11 is lifted and lowered together with the lift guide member 13. The link mechanism 12 also has an effect of supporting the seat member 11 when the seat member 11 is stopped and lifted.

  The link mechanism 12 is not particularly limited, and is configured by combining a pair of left and right multi-node links that move along the same path. The left multi-node link is connected to the left side of the seat member 11 and supports the left portion of the seat member 11. The right multi-node link is connected to the right part of the seat member 11 and supports the right part of the seat member 11.

  The connecting portion between the link mechanism 12 and the seating member 11 includes a connecting portion provided on the first side edge of the seating member 11 (the side edge on the opposite side of the lifting guide member 13), and the connecting portion. There is a connection portion provided in a range close to two side edges (side edges on the side close to the lifting guide member 13). In the former connection portion, the upper end of the link and the seat member 11 are connected so as to be rotatable about the movable fulcrum 31. In the latter connection portion, the upper end of the link is connected so as to be rotatable about the movable fulcrum 33. The seat member 11 is provided with a slide guide 32 that is long in the horizontal direction, and the movable fulcrums 31 and 33 are movably connected along the slide guide 32. In addition, the movable fulcrum 31 may be connected to the seat member 11 on the first side edge portion to be a fixed fulcrum, and the movable fulcrum 33 may be movably connected along the slide guide 32.

  A roller 26 is provided at the lower end of the link mechanism 12 and closer to the first side edge of the seat member 11 (however, FIG. 3 shows the roller to prevent complication. Absent). The roller 26 moves while rotating the bottom of the bathtub as the seat member 11 moves up and down. As described above, the lower end of the link mechanism 12 is movable closer to the first side edge of the seat member 11. The lower end of the link mechanism 12 on the side close to the second side edge is fixed to the lower end of the elevating guide member 13 and the movement with respect to the bathtub 80 is restricted.

  Note that a frame having a guide groove extending in the horizontal direction may be provided at the lower end of the link mechanism 12 instead of the roller 26. In this case, the lower end of the link mechanism 12 moves in the horizontal direction along the guide groove of the frame. However, since the space occupied in the height direction can be reduced when the roller 26 is provided compared to the case where the frame is provided, the seat member 11 can be lowered closer to the bathtub bottom.

  As described above, the configuration in which the lower end of the link mechanism 12 is movable and the movable support points 31 and 33 at the upper end are movable, the seat member 11 moves up and down along a curved path, and the second side edge portion of the seat member 11 follows. An elevating guide member 13 is provided so as to move. At this time, the seat member 11 is maintained in a horizontal posture, and the seat member 11 is positioned on the upper end of the edge of the bathtub in the highest position.

  The raising / lowering guide member 13 guides the second side edge of the seat member 11 when the seat member 11 moves up and down. Specifically, the raising / lowering guide member 13 is arrange | positioned adjacent to the one side wall of the bathtub 80 so that it may reach from the outer side of a bathtub to the bathtub bottom part above the bathtub edge. The raising / lowering guide member 13 has a second side edge of the seat member 11 that is close to the bathtub bottom from the first position Ps1 above the upper edge of the bathtub edge or above the bathtub edge and outside the bathtub edge. Guide at position Ps2. When the seat member 11 rises most, the seat member 11 is disposed above the lifting guide member 13 and is located above the upper end of the edge of the bathtub 80, so the seat member 11 is also supported by the edge of the bathtub 80. When the bather is seated, the seat member 11 is stably supported. As shown in FIG. 4, the elevating guide member 13 has a guide pipe 41, a detachment preventing roller 42, and a cover 43. It has a strip shape with a predetermined width.

  The guide pipe 41 supports the lifting guide member 13 and functions as a skeleton of the lifting guide member 13.

  The detachment prevention roller 42 includes a roller portion 42-1 housed inside the cover 43 and a groove provided along the extending direction of the cover 43 provided on the lift guide member 13 side of the cover 43 (FIG. 1, FIG. 2 (not shown in FIG. 2) and a connecting portion 42-2 protruding outward. The roller part 42-1 moves up and down in the cover 43, and the connection part 42-2 is connected to the base plate 21 of the seat member 11. This prevents the seat member 11 from being detached from the lifting guide member 13. The detachment prevention roller 42 is connected to the seating member 11 so as to swing its head up and down, so that even if the seating member 11 moves up and down and the angle formed between the seating member 11 and the cover 43 changes, this change is followed. Has been.

  The cover 43 has a space for accommodating the guide pipe 41, the detachment prevention roller 42, and the cable 54 inside. Further, the cover 43 is provided with a pair of slits 44 that are spaced apart in parallel in the width direction in the vertical direction, and a part of the cable guide portion 14 is inserted into the slits. A cable 54 is passed through the slit 44. Thereby, exposure of the cable 54 can be prevented. The slit 44 may be replaced with a groove, and the cable 54 may be passed through the cover 43.

  In this manner, the lifting guide member 13 guides the seat member 11, and the link mechanism 12 is connected to the first side edge of the seat member 11 to support the seat member 11, so that the seat member 11 is stopped and At the time of raising and lowering, the stability of the seat member 11 can be increased. Moreover, since the raising / lowering guide member 13 can be hold | maintained only to one side wall of the bathtub 80, the raising / lowering apparatus 1 can be installed in a bathtub compactly.

  As shown in FIG. 3, the drive device 15 includes a motor 51 (corresponding to a drive unit), a drum 52, and a cable 54 housed in a case. The motor 51 has a motor shaft connected to the rotation shaft of the drum 52, and rotates the drum 52 upon receiving electricity from a power source (not shown). In FIG. 3, the driving device 15 is provided on the elevating guide member 13, and may be provided separately from the elevating guide member 13 as shown in FIGS. 5 to 7.

  A cable 54 is wound around the drum 52. The drum 52 winds or unwinds the cable 54 when the motor 51 rotates forward or backward.

  The pulley 53 is provided at the end of the elevating guide member 13 on the outer side of the bathtub, and a part of the cable 54 is hooked to change the moving direction of the cable 54 from the elevating guide member 13 toward the drive device 15.

  The cable 54 is connected at one end to the lower surface of the base plate 21 of the seat member 11 and from the second side edge portion of the base plate 21 to the connection portion 55 closer to the center. It is paid out. The motor 51 may be driven only in the winding direction, and the cable 54 may be fed out by the own weight of the seat member 11 on which the person bather is seated.

  The cable guide portion 14 is provided on the second side edge portion of the seat member 11, and a portion of the cable 54 that is stretched between the connection portion 55 and the motor 51 is hung. The seat member 11 is provided with a pair of left and right cable guide portions 14. A part of the cable guide portion 14 is inserted into the slit 44 of the elevating guide member 13 so that the cable guide portion 14 is guided in the elevating direction and the movement in the lateral direction is restricted. By restricting the movement of the cable guide portion 14 in the lateral direction, the swinging of the seating member 11 in the lateral direction is suppressed, and the bather can take a bath in a stable state. The cable guide portion 14 is formed so as to protrude from the second side edge portion of the seat member 11 to one side. In the cable guide portion 14, a groove for hooking the cable 54 has an arcuate curve and is formed in a range corresponding to a portion that protrudes most from the lower portion of the cable guide portion 14.

  When the seat member 11 is located at the bottom of the bathtub, the cable 54 is hung from the lower portion of the cable guide portion 14 to the side edge portion, and the cable between the pulley 53 and the most projecting portion of the cable guide portion 14. The direction in which 54 is pulled is the same as the direction in which the seat member 11 moves. On the other hand, when the seat member 11 is located above the upper end of the bathtub edge, the cable 54 is hung on a part of the lower portion of the cable guide portion 14, and the pulley 53 and the most protruding portion of the cable guide portion 14 are connected. The direction in which the cable 54 is pulled in between is the horizontal direction or the downward direction, and the direction in which the seat member 11 moves is the horizontal direction.

  Thus, the direction in which the cable 54 pulls the seat member 11 changes depending on the lift position of the seat member 11. However, in the connection portion 55 between the cable 54 and the seat member 11, the cable guide 14 is configured to change the angle of the seat member 11 with respect to the lifting guide member 13 so that the cable 54 can smoothly follow. Therefore, it is not necessary to consider that the direction of the cable 54 changes at the connection portion 55, and the connection portion 55 between the cable 54 and the seating member 11 can be made a simple structure. Further, in order to follow the change in the direction of the cable 54, it is necessary to connect the cable 54 to a rotating member that changes the direction of the cable 54 in a rotatable manner. An inexpensive and highly durable connection is possible.

  Next, in the above-described lifting device 1, the operation when the handle has two support columns 27 and no connection member 25 will be described with reference to FIGS. 5 to 8. Fig.5 (a) is a top view which shows a mode that the bather seated on the seat part 22 with the bathtub 80 in the back, FIG.5 (b) is a side view of Fig.5 (a). In these drawings, the seat member 11 is raised upward from the upper end of the bathtub edge, and a part of the seat member 11 is projected to the outside of the bathtub. In such a state, the bather can enter the bathroom together with the wheelchair without the lifting device 1 being in the way. Moreover, since there is no big difference in the height of the seat surface of the wheelchair and the height of the seating part 22 and a part of the seating member 11 protrudes outside the bathtub, it is possible to easily transfer from the wheelchair to the seating part 22.

  Here, an assistant who assists or assists in bathing care or support moves the bather's feet into the bathtub, and the orientation of the bather seated on the rotatable seating portion 22 is 90 ° together with the seating portion 22. Rotate left. This is shown in FIGS. 6 (a) and 6 (b). FIG. 6A and FIG. 6B show a state where the bather holds the first handle 23 located in the front with both hands.

  Next, when the assistant or the bather himself operates the lowering switch of the seat member 11, the motor 51 is driven and the cable 54 is drawn out from the drum 52. The seat member 11 is guided by the elevating guide member 13 and descends along a path that is partially curved from above the upper end of the bathtub edge to a position near the bathtub bottom. That is, the seat member 11 descends while moving from the outside of the bathtub to the inside of the bathtub. FIGS. 7 (a) and 7 (b) show the state during the descent, and FIGS. 8 (a) and 8 (b) show the state where the descent is completed.

  When the descent is completed, the bather can take a bath in the hot water, and can have his / her back lean against the side wall of the second handle 24 or the bathtub 80 and can take an easy posture.

  When bathing is completed, the assistant or the bather himself operates the ascending switch of the seating member 11, and reverses the procedure at the time of bathing, so that the seating member 11 is moved from the position close to the bottom of the bathtub to the upper end of the bathtub edge. To rise.

  As described above, in the lifting device 1 of the present embodiment, the lifting guide member 13 disposed along one side wall of the bathtub 80 has the second side edge of the seat member 11 as the upper end of the bathtub edge. Or the first position Ps1 above the upper edge of the bathtub edge and outside the bathtub edge, and the second position Ps2 closer to the bathtub bottom than the upper edge of the bathtub edge. The seat member 11 is connected to a portion closer to the first side edge than the center and to the second side edge of the seat member 11 on the opposite side of the first side edge, and the lower end is located at the bottom of the bathtub. The member 11 is moved up and down along a path that is at least partially curved, and the seat member 11 reciprocates between the upper end of the bathtub edge and a position closer to the bathtub bottom than the upper end of the bathtub edge. Thereby, since the 1st side edge part and 2nd side edge part of the seat member 11 are each supported at the time of raising / lowering, the sense of stability at the time of raising / lowering of the seat member 11 can be improved. Since the link mechanism 12 supports a portion of the seat member 11 that is close to the first side edge, it is not necessary to connect to the cable 54, and the apparatus can be made compact.

<Modification>
In the above-described embodiment, the case where the first handle 23 and the second handle 24 are arranged horizontally with respect to the seating portion 22 has been described. However, the present invention is not limited to this and may be arranged obliquely. For example, as shown in FIG. 9, the first handle 23 and the second handle 24 may be moved so that the angle can be changed to be perpendicular to the seating portion 22. Thereby, when a healthy person takes a bath, the first handle 23 and the second handle 24 can be prevented from getting in the way, and it is an obstacle to seat the bather during the care. This is because there are cases.

  Further, as shown in FIG. 10, even if the angle is changed so that the second handle 24 is perpendicular to the seating surface while the first handle 23 is horizontal with respect to the seating portion 22. Good. Furthermore, the seat member 11 does not necessarily need to include the second handle 24.

  In the above embodiment, the motor has been described as an example of the drive unit. However, the present invention is not limited to this, and the drive unit may be configured to manually generate power such as a rotary lever.

  In the above embodiment, the motor has been described as winding or unwinding the cable to drive the lifting and lowering of the seating member, but the motor only winds the cable and raises the seating member. You may make it operate | move.

  Further, a configuration may be added in which a cable is provided so as to pull the seat member from the lower end portion of the elevating guide member, and the seat member descends when the motor winds the cable.

  Moreover, in the said embodiment, although the cable was demonstrated to the example, this invention is not limited to this. For example, a belt may be used instead of a cable.

  The present invention can be applied to a general bathtub.
