[0007] Patent Document 2: Japanese Patent Application Publication No. 2015-202334 Summary of the invention

[0008] Problems to be solved by the invention

[0009] In the armrest device described in Patent Document 1, the care receiver leans his or her thighs against the cushioning body and places both hands on the cushioning body provided at the upper end, thereby being able to maintain a standing posture safely and reliably without feeling any physical burden.

[0010] In addition, the standing assisting device of Patent Document 2 can not only assist the user in maintaining a standing posture for a short period of time, but also allows the user to put on and take off clothes by holding the upper body.

[0011] However, when the user stands up from a wheelchair or toilet and leans on the standing aid, the user sometimes changes the direction and position of the legs in order to get closer to the standing aid. In addition, when the user sits on the wheelchair or toilet from the standing aid, the user sometimes moves the legs in order to change the direction of the body. During these actions, the knees may be unable to exert force due to motor paralysis, reduced muscle strength, etc., and the user's knees may bend unexpectedly and the user cannot maintain a standing posture. On the other hand, when only a knee abutment portion as described in Patent Document 2 is provided to suppress knee bending, the knee abutment portion may hinder the movement of the user's legs and change of direction.

[0012] An object of the present invention is to provide a care device that can assist a user in maintaining a standing posture, and to suppress unintentional knee bending without hindering movement or change in orientation of the user's legs.

[0013] Solutions to Solve Problems

[0014] The care device of the first scheme is used to enable the user to maintain a standing posture by himself, and it comprises: a first base, which is arranged on the floor or the wall; an upper body support part, which is arranged on the first base and can be used for the front surface of the upper body of the user in the standing posture to lean on; a second base, which is arranged on the floor, the wall or the first base; and a support part, which is arranged on the second base and is configured below the upper body support part, and can support part or all of the user's upper calf from the knee to the front when the knee of the user leaning on the upper body support part is bent.

[0015] In the nursing device, the front surface of the upper body of the user in a standing position can lean against the upper body support part. In addition, when the knee of the user in a standing position leaning against the upper body support part bends, the support part supports part or all of the upper calf from the knee to the front from below, thereby suppressing the knee from bending. In a state where the knee is not bent, the support part does not hinder the movement or change of direction of the user's legs.

[0016] According to a second aspect, in the care device of the first aspect, a portion of the support portion closest to the front is located closer to the front than a portion of the upper body support portion closest to the front.

[0017] In this care device, the portion closest to the front of the support portion is located closer to the front than the portion closest to the front of the upper body support portion. Therefore, even if the knees of the user who is standing leaning on the upper body support portion are bent, the knee bending can be suppressed in the initial stage of the knee bending.

[0018] According to a third aspect, in the care device of the second aspect, the support portion is formed so as not to abut against the user's knee and the upper calf facing the user when the user's knee leaning on the upper body support portion is in an extended state.

[0019] In this care device, when the knees of the user leaning on the upper body support part are in an extended state, the knees of the user and the upper part of the calves facing the support part do not abut against the support part, so the movement or change of direction of the user's legs will not be hindered.

[0020] A fourth aspect is that, in the care device of the third aspect, the frontmost portion of the support portion is located below the user's extended knee leaning against the upper body support portion and further from the upper calf facing the user.

[0021] In this care device, due to the configuration of the support part, when the user's knees leaning on the upper body support part are in an extended state, the user's knees and the upper part of the calf facing the user do not abut the front side of the support part.

[0022] A fifth aspect is the care device according to any one of the first to fourth aspects, wherein the support portion can be stored inward from a supportable state.

[0023] In this care device, the support portion can be stored from a supportable state, so it is easy to ensure a turning space for the wheelchair even in a limited space.

[0024] Effects of the Invention

[0025] According to the present invention, in a care device that can assist a user in maintaining a standing posture, it is possible to suppress unintentional knee bending without hindering the movement or change in orientation of the user's legs. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Hereinafter, the mode for implementing the present invention will be described based on the accompanying drawings. The constituent elements represented by the same symbols in the various drawings refer to the same or identical constituent elements. In addition, in the embodiments described below, repeated descriptions and symbols are sometimes omitted.

[0035] exist Figures 1 to 6 The nursing device 10 of this embodiment is a nursing device for enabling the user S to maintain a standing posture by himself. The nursing device 10 includes a support device 30 as an example of a first base, an upper body support part 20, a support part 40 as an example of a second base, and a support part 50. Figure 3 In the embodiment, the care device 10 is provided near a toilet 16 in a toilet T used by a wheelchair user. A reclining device 15 is provided around the toilet 16. Considering the use of the care device 10 on a wheelchair (not shown), the care device 10 is provided such that the upper body supporting portion 20 and the support portion 50 face the middle direction between the front-rear direction F of the toilet 16 and the in-and-out direction E of the wheelchair.

[0036] The support device 30 is installed on the floor Y of the toilet T. Specifically, for example, the support 31 is mainly composed of a base plate 32 installed on the floor Y and a support 31 of a hollow tube installed upright on the base plate 32. In addition, the support device 30 is installed upright from the floor Y in the vertical direction upward by fixing the base plate 32 to the floor Y. A rib-shaped reinforcement member 33 for suppressing the inclination of the support 31 is installed on the lower end of the support 31 and the base plate 32.

[0037] The upper body support part 20 is provided on the support column 31, and is a part on which the front surface part SA of the upper body of the user S in a standing position can lean. The front surface part SA of the upper body is mainly the chest. Alternatively, in addition to the chest of the user S, up to the abdomen or the head may lean on the upper body support part 20. The upper body support part 20 may also be a part that supports the standing posture of the user S. As an example, the upper body support part 20 has a pair of left and right vertical grips 21 extending in the up-down direction, respectively, and each vertical grip 21 is formed in a curved shape in a convex manner toward the near front side. The interval between each vertical grip 21 is set to be smaller than the shoulder width of the user S. The user S can lean on the pair of vertical grips 21 through the front surface part SA of the upper body. In addition, the "near front side" refers to the side of the user S leaning on the upper body support part 20 through the front surface part SA of the upper body (the near front side as viewed from the user S).

[0038] The lower ends of the pair of vertical grips 21 are connected to each other by a lower connecting portion 22 extending substantially horizontally. In the example shown in the figure, the pair of vertical grips 21 and the lower connecting portion 22 are integrally formed, but the lower connecting portion 22 may be formed separately from the pair of vertical grips 21. The upper ends of the pair of vertical grips 21 are connected to each other by an upper connecting portion 23. The upper connecting portion 23 has a pair of first wall portions 23A extending from the pair of vertical grips 21 to the depth side, and a second wall portion 23B connecting the depth side ends of the pair of first wall portions 23A to each other. The second wall portion 23B is located on the depth side of the pair of vertical grips 21 and is fixed to a base portion 26 provided at the upper end of the support column 31. A support portion not shown is provided on the upper portion of the support column 31, and the base portion 26 is fixed to the support portion. A pad portion 24 is provided on the base portion 26. The pad portion 24 is located between the upper connecting portion 23 and the lower connecting portion 22 between the pair of vertical grips 21. In addition, the “deeper side” refers to the front side of the user S who leans on the upper body supporting part 20 through the front surface part SA of the upper body.

[0039] The support portion 40 is provided on the pillar 31. In the present embodiment, the support portion 40 is provided on the pillar 31 at a position lower than the upper body support portion 20. The support portion 40 has, for example, a mounting portion 42 and a pair of arm portions 44. The mounting portion 42 is mounted at a predetermined height, for example, in a manner of clamping the pillar 31 in the radial direction. In addition, the mounting portion 42 may also be formed so as to be able to change the mounting height relative to the pillar 31. The pair of arm portions 44 are supported in the support portion 40 so as to be able to rotate within a predetermined range. The predetermined range refers to a range required for switching the support state and the storage state of the support portion 50 described later. The support portion 40 may also have a stopper or a plunger, etc., which can maintain the angular position of the arm portion 44 at the upper and lower limits of the predetermined range.

[0040] like Figure 2 As shown, the support portion 50 can also be made to be able to be stored inward. As described above, the pair of arms 44 supporting the support portion 50 can rotate within a predetermined range in the support portion 40. In the example shown in the figure, the state in which the pair of arms 44 are rotated upward to flip the support portion 50 is the stored state of the support portion 50. The stored state can also be a structure maintained by a stopper or plunger that can maintain the angular position of the arm portion 44. On the other hand, the state in which the pair of arms 44 are rotated downward from the stored state to make the arm portion 44 approximately horizontal is the supportable state of the support portion 50 ( Figure 1 The support portion 50 can support the knee SB of the user S whose knee is bent in a supportable state.

[0041] The support portion 50 is provided on the support portion 40 and is arranged below the upper body support portion 20, and can support a part or all of the upper part of the lower leg from the knee to the front of the user S (hereinafter referred to as "knee SB") from below when the knee of the user S leaning on the upper body support portion 20 is bent. For example, the support portion 50 has a frame 52 and a pad portion 54. The frame 52 connects the ends of the near front side of the pair of arm portions 44 to each other and is arranged to be approximately horizontal. The frame 52 extends in the left and right direction of the user S leaning on the upper body support portion 20 through the front surface portion SA of the upper body. The two ends of the frame 52 protrude more to the left and right than the ends of the near front side of the pair of arm portions 44. The length of the frame 52 is set to be larger than the distance between the two knees of the user S in the standing state leaning on the upper body support portion 20, and the knee can be supported even if the position of the leg changes slightly to the left and right.

[0042] The cushion part 54 is provided to cover the frame 52, for example, from the top to the front side and further to the bottom. The cushion part 54 has, for example, polyurethane foam and a surface. The outer shape of the cushion part 54 is formed, for example, in an arc-shaped cross section. In addition, the range of the arc-shaped cross section of the cushion part 54 is not limited to the example shown in the figure. It is sufficient as long as at least the range of the cushion part 54 that contacts the knee SB of the user S with the knee bent is an arc-shaped cross section.

[0043] In addition, if Figure 5 As shown, when the knee of the user S in the standing posture leaning on the upper body support part 20 bends, the knee SB is supported from below by the support part 50 in the supportable state, and the knee bending can be suppressed. The knee joint angle θ when the support part 50 supports the knee SB is preferably greater than 10 degrees, and more preferably greater than 20 degrees. The knee joint angle θ when the support part 50 supports the knee SB is preferably less than 60 degrees, and more preferably less than 50 degrees.

[0044] In the supportable state of the support portion 50, the portion closest to the front of the support portion 50, that is, the portion closest to the front of the cushion portion 54, may be located closer to the front than the portion closest to the front of the upper body support portion 20, that is, the portion closest to the front of the vertical grip 21. In addition, the support portion 50 may be formed so that, in the supportable state, it does not abut against the knee SB of the user S who is leaning on the upper body support portion 20 when the knee is in an extended state. In other words, the portion closest to the front of the support portion 50 may be located below the extended knee of the user S who is leaning on the upper body support portion 20 and further to the depth of the upper calf facing the support portion 50 ( Figure 4 ).

[0045] Furthermore, the support portion 50 may be formed so as not to abut against the knee SB of the user S when the user S bends his knee in the support state. Figure 6As shown, even if the user S bends his knees to put on and take off the clothes of the lower body, the knee SB of the user S does not come into contact with the support part 50. Therefore, the support part 50 is unlikely to become an obstacle when putting on and taking off clothes.

[0046] Specifically, in the supportable state of the support portion 50, the distance A in the front-to-back direction between the portion closest to the front of the support portion 50 and the portion closest to the front of the upper body support portion 20 is, for example, about 20 mm. In addition, the height H from the floor Y to the uppermost position of the support portion 50 is about 400 mm. Although the height of the knee varies depending on the physique of the user S, by setting such a size, the knee of the user S with a height of, for example, 140 to 180 cm can be supported by the support portion 50 without discomfort.

[0047] (effect)

[0048] This embodiment is constructed as described above, and its function will be described below. When the user S transfers between the wheelchair and the toilet 16, the user S temporarily stands up to put on and take off clothes on the lower body. Figure 4 In the present embodiment, the front surface SA of the upper body of the user S in the standing position can lean against the upper body support part 20. When the knees of the user S leaning against the upper body support part 20 are in an extended state, the knees SB of the user S do not abut against the support part 50 in the supportable state, so the movement or change of the direction of the legs of the user S is not hindered.

[0049] In addition, if Figure 5 As shown, when the knee of the user S who is standing leaning on the upper body support part 20 bends, the knee SB is supported from below by the support part 50 in a supportable state, so that the knee SB can be suppressed from bending. In particular, the portion closest to the front side of the support part 50 is located closer to the front side than the portion closest to the front side of the upper body support part 20, so that even if the knee of the user S who is standing leaning on the upper body support part 20 bends, the knee bending can be suppressed in the initial stage of knee bending. By appropriately setting the position of the support part 50, even if the height of the knee SB varies according to the physique of the user S, the support part 50 can support the knee SB in the same manner. By making the upper surface and the front surface of the support part 50 curved, even if the direction in which the knee SB contacts the support part 50 is slightly changed, the knee SB can be supported in the same manner.

[0050] As described above, according to the present embodiment, in the care device that can assist the user S in maintaining a standing posture, it is possible to suppress unintentional knee bending without hindering the movement of the user's S legs or changes in direction.

[0051] exist Figure 2The bathroom T used by the wheelchair user shown requires a turning space for the wheelchair, but in the care device 10 of this embodiment, the support part 50 can be retreated from a supportable state to a storable state, so it is easy to ensure the turning space for the wheelchair even in a limited space such as the bathroom T.

[0052] [Other embodiments]

[0053] An example of the embodiment of the present invention has been described above, but the embodiment of the present invention is not limited to the above, and it is of course possible to carry out the present invention in various modified forms without departing from the gist of the present invention.

[0054] As an example of the first base, the support device 30 is cited, but the first base may also be a wall-mounted bracket. That is, the upper body support 20 may also be mounted on the wall K via the wall-mounted bracket. The upper body support 20 is not limited to the above-mentioned embodiment, as long as the front surface SA of the upper body of the user S in a standing position can lean against it.

[0055] The support portion 40 as an example of the second base is provided on the support column 31, but may be provided on the base plate 32. In addition, the second base may be provided on the floor Y or the wall K. In order to ensure a turning space for the wheelchair, it is preferred that the support portion 50 can be stored inward from a supportable state, but may be fixed in a supportable state.
