[0026] (Embodiment 1) FIG. 1 is a side view of a rehabilitation support wheelchair 200 according to a first embodiment of the present invention, and FIG. 2 is a top view and a front view of the rehabilitation support wheelchair (partially omitted).

[0027] This rehabilitation assistance wheelchair 200 includes a pair of left and right frames 210, a pair of cross arms 220 supporting the pair of left and right body frames 210, and a pair of left and right main driving wheels 230.

[0028] Furthermore, an assist device 100 for assisting rehabilitation is provided at approximately the central axis of the rehabilitation assist wheelchair 200. The assist device 100 is provided with an equipment body 110 having an axis in the longitudinal direction, a first connecting member 10 connectable to a rotating shaft portion 240 of a pair of left and right main driving wheels 230 at one end in the longitudinal direction of the equipment body 110, and a platform 130 on which the feet of a rider are placed, provided at the other end in the longitudinal direction.

[0029] The support tool 100 comprises a first connecting member 10 for connecting the tool body 110 to the approximate center of the rear part of the wheelchair 200 (for supporting the detailed support tool 100 and achieving adjustments such as changing the height of the mounting platform 130), and a second connecting member 20 for connecting the tool body 110 to a position forward of the first connecting member 10 of each of the left and right body frames 210 of the wheelchair 200. Here, the first connecting member 10 is provided on an upper portion of one end of the tool body 110 in the longitudinal direction, and the second connecting member 20 is provided between the other end and one end of the tool body 110, here in the central part of the tool body 110.

[0030] The rehabilitation support wheelchair 200 of the present invention includes the support device main body 110, the first connecting member 10, the second connecting member 20, the rotating shaft portion 240 of the main driving wheel 230, and the mounting base 130, which will be described in detail below.

[0031] (Rehabilitation Assistance Wheelchair 200) The rehabilitation support wheelchair 200 of the present invention has a pair of left and right frames 210 having the structure of a normal wheelchair, a pair of cross arms 220 (in this embodiment, foldable frames) that support the pair of left and right body frames 210 of the rehabilitation support wheelchair 200, a pair of left and right main driving wheels 230, and rotating shaft portions 240 of the pair of left and right main driving wheels 230, and further has a support device main body 110, a first connecting member 10, a second connecting member 20 that constitute the support device 100, and a support base 130 on which the rider's feet are placed.

[0032] (Apparatus body 110) The tool body 110 is a cylindrical body extending in the longitudinal direction of the rehabilitation support wheelchair 200. The tool body 110 has, at one end, a first connecting member 10 connectable to the rotating shafts 240 of the pair of left and right main driving wheels 230 of the rehabilitation support wheelchair 200, at the other end, a platform 130 for placing the feet of the rider, and a second connecting member 20 for fixing to each of the pair of left and right body frames 210 of the rehabilitation support wheelchair 200 between the one end and the other end.

[0033] (First connecting member 10) The first connecting member 10 is a member for connecting the tool body 110 to a rotating shaft portion 240 of a main driving wheel 230 of the rehabilitation assistance wheelchair 200.

[0034] 2(a) and (c), the first connecting member 10 is a cylindrical body capable of containing one rotating shaft body 241 that connects the rotating shaft parts 240 of the left and right main driving wheels 230. A hole is provided in a part of the cylindrical body toward the center of the cylindrical body, into which a fastening means 11 such as a bolt or a screw can be inserted. By inserting the fastening means 11 such as a bolt or a screw into the hole of the first connecting member 10, the first connecting member is integrated with the rotating shaft part of the main driving wheel 230, and the rehabilitation of the main driving wheel 230 is transmitted to the support device main body 110.

[0035] The connection between the tool body 110 and the first connecting member is made via a cam 12 as shown in FIG.

[0036] A more detailed movement of the assistive device body 110 is shown in FIG.

[0037] As shown in FIG. 3(a), when the driving wheel 230 connected to the rotating shaft part 240 of the rehabilitation support wheelchair 200 is gradually rotated from a state in which the first connecting member 10 is initially at the upper end position of the cam 12, the first connecting member 10 connected to the rotating shaft part 240 (rotating shaft body 241) also rotates following it. At that time, since the support tool body 110 is connected to the first connecting member 10 via the cam 12, one end of the tool body 110 rises upward from the initial state. Note that since the tool body 110 is fixed to the frame 210 at a position between the one end and the other end by the second connecting member, the other end (the position where the mounting table 130 is arranged) moves to a position lower than before.

[0038] Furthermore, if it is rotated further from this state, it will return to the same position as in Figure 3(a), i.e., the first connecting member 10 returns to the position of the upper end of the cam 12 (the position where the other end of the support instrument main body 110 is located upward).

[0039] With this structure, the rotation of the main wheel 230 caused by the caregiver moving the rehabilitation support wheelchair 200 is converted into vertical rehabilitation of the support device main body 110 via the rotating shaft body 241 and the cam 12 of the first connecting member 10.

[0040] The user can perform rehabilitation in the vertical direction simply by placing his / her feet on the placement plate 131 of the placement platform 130, and thus it is possible to easily support appropriate rehabilitation.

[0041] (Second connecting member 20) The second connecting member 20 is a member for fixing the tool body 110 to each of a pair of left and right body frames 210 of the rehabilitation support wheelchair 200, and is provided on the tool body 110. The tool body 110 is configured to be rotatable about the second connecting member 20. The specific configuration of this second connecting member 20 is not limited, but here, it is structured to fix the tool body 110 to the pair of left and right body frames 210 of the wheelchair 200.

[0042] As shown in Figure 2(b), the second connecting member 20 has a second shaft member 21 extending in a direction approximately perpendicular to the longitudinal direction of the device main body 110, and a hook portion 22 for engaging one end of the second shaft member 21 with a pair of left and right body frames 210 of the wheelchair 200.

[0043] (Placement table 130) The support base 130 is provided at the other end of the support instrument body 110 for the user to place his / her feet on, as shown in FIG. 2(a).

[0044] Here, the mounting table 130 includes a mounting plate 131 and a rotating shaft portion 132 extending in the longitudinal direction of the support instrument main body 110. As shown in Fig. 2(d), the mounting plate 131 can rotate about the rotating shaft portion 132, and as a result, the mounting plate 131 can be folded according to the situation. Furthermore, the height of the mounting table 130 can also be adjusted.

[0045] 4 shows the details of the rotating shaft body 241 and the mounting state of the rotating shaft body 241. The rotating shaft body 241 has a shaft body 241a and an engagement piece 241b that can engage with one of the pair of left and right main driving wheels 230. The rotating shaft body 241 is inserted so as to connect from the rotating shaft part of one main driving wheel 230 to the rotating shaft part 240 of the other main driving wheel 230. At that time, by engaging the engagement piece 241b of the rotating shaft body 241 with one of the main driving wheels 230 (more specifically, between the spokes), it becomes linked to the rotation of the engaged main driving wheel 230. The other main driving wheel 230 that is not engaged with the engagement piece 241b is in a free state.

[0046] In the above embodiment, the rotating shaft portion 240 is linked to the main driving wheel 230, and the mounting base 130 moves up and down as the main driving wheel 230 rotates. However, it is also possible to prevent the mounting base 130 from moving up and down even when the main driving wheel 230 rotates by releasing the connection between the main driving wheel 230 and the tool body 100 by loosening the fastening means 11.

[0047] In this way, the passenger can simply place his / her feet on the platform 130, allowing it to function as a footrest.
