  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In order to facilitate the understanding of the description, the same components are denoted by the same reference numerals as much as possible in the drawings, and redundant description will be omitted.

  A toilet wheelchair according to an embodiment of the present invention will be described with reference to FIG. A toilet wheelchair 1 shown in FIG. 1 is provided on a seat surface portion 10 on which a user can sit and a lower portion of the seat surface portion 10 to support the seat surface portion 10 and to arrange the seat surface portion 10 above the toilet. A support frame 20 that forms a toilet storage space, a moving means 30 that is provided at a lower portion of the support frame 20 and that can move the toilet wheelchair 1, a backrest 40, an armrest 50, and a footrest 62.

  The moving means 30 includes a left front wheel 31 provided at the left front portion of the support frame 20, a left rear wheel 32 provided at the left rear portion of the support frame 20, and a left side provided near the left center of the support frame 20. Auxiliary wheel 33, right front wheel 34 provided at the right front part of support frame 20, right rear wheel 35 provided at the right rear part of support frame 20, and right side provided near the right center of support frame 20 And an auxiliary wheel 36.

  The support frame 20 includes a left frame 21 to which a left front wheel 31, a left rear wheel 32, and a left auxiliary wheel 33 are fixed; a right frame 22 to which a right front wheel 34, a right rear wheel 35 and a right auxiliary wheel 36 are fixed; A front frame 23 that connects the front end of the frame 21 and the front end of the right frame 22, a left seat support frame 24 that supports the left end of the seat 10, and a right seat that supports the right end of the seat 10 It includes a support frame 25, a left connection frame 26 that connects the left seat support frame 24 and the left frame 21, and a right connection frame 27 that connects the right seat support frame 25 and the right frame 22.

  The left frame 21 and the right frame 22 will be described with reference to FIGS. 2 and 3. The left frame 21 has a bent portion 213 near the center, and includes a left front frame 211 positioned on the front side of the bent portion 213 and a left rear frame 212 positioned on the rear side of the bent portion 213. Similar to the left frame 21, the right frame 22 has a bent portion 223 near the center, the right front frame 221 positioned on the front side of the bent portion 223, and the right rear side positioned on the rear side of the bent portion 223. Frame 222.

  The left rear frame 212 and the right rear frame 222 rotate outward (directions away from each other) around the bent portions 213 and 223, respectively. This rotation changes the relative positional relationship between the left frame 21 and the right frame 22 when the toilet wheelchair 1 is viewed from above.

  With reference to FIG. 4, an example of the use state of the wheelchair 1 for toilets in this embodiment is demonstrated. FIG. 4 is a diagram illustrating a relationship between the toilet bowl 9 and the left frame 21 when the toilet wheelchair 1 entering the toilet room is viewed from above. In FIG. 4, the entrance of the toilet is located diagonally to the left of the toilet 9. The toilet wheelchair 1 obliquely enters the toilet room from the entrance of the toilet in a backward-facing state, and the rear end portion of the left rear frame 212 is in contact with the side surface of the toilet bowl 9. The left rear frame 212 rotates around the bent portion 213.

  As described above, the left rear frame 212 moves toward the outside along the side surface of the toilet bowl 9 after coming into contact with the toilet bowl 9. It is possible to avoid an interference state where the wheel 30 interferes with the entrance of the toilet room and the toilet 9 and the wheelchair cannot rotate any more. That is, even in a narrow toilet at the side entrance, the toilet wheelchair 1 can be reliably reached to the position above the toilet bowl 9.

  Here, the case where the left rear frame 212 is movable outward has been described. However, if the outer peripheral shape of the left frame 21 or the right frame 22 of the toilet wheelchair 1 can be deformed, the toilet is a narrow toilet with a side entrance. However, the toilet wheelchair 1 can reach the upper position of the toilet bowl 9. The deformation of the outer peripheral shape includes changing the relative positional relationship between the left frame 21 and the right frame 22 when the toilet wheelchair 1 is viewed from above, or changing the shape of the left frame 21 or the right frame 22 itself. Includes changing.

  The toilet wheelchair 1 includes frame deformation means for deforming the outer peripheral shape of the left frame 21 or the right frame 22. The deformation of the outer peripheral shape by the frame deformation means will be specifically described below.

  With reference to FIG. 5, the case where the outer peripheral shape of the right frame is deformed by moving the front side of the right frame will be described. In this case, after the left rear wheel 72 abuts on the toilet 9, the front side 821 of the right frame 82 is moved inward to avoid an interference state. However, since there are the foot 61 and the footrest 62 of the seated user above the front side of the right frame 82 and the left frame 81, even if the front side 821 of the right frame 82 is moved inward, the user's foot. It is assumed that 61 and the footrest 62 hit the entrance of the toilet room. In particular, when the footrest 62 comes into contact with the entrance of the toilet room, the footrest 62 is in an interference state and may not be able to rotate any more.

  With reference to FIG. 6, the case where the outer peripheral shape of the left frame is deformed by rotating the rear side of the left frame inward will be described. In this case, after the left rear wheel 72 abuts on the toilet 9, the rear side 812 of the left frame 81 is turned inward, so that an interference state can be avoided. However, when the rear side of the left frame 81 is turned inward, the area between the wheels formed by connecting the four wheels decreases, and the center of gravity stability of the toilet wheelchair 1 decreases. If it demonstrates concretely with reference to FIG. 7, the area between wheels at the time of normal use will become the area S1 formed by connecting the four wheels 71, 72, 75, and 74. FIG. On the other hand, the area between the wheels when the frame is deformed is an area S2 formed by connecting the four wheels 71, 73, 75 and 74. That is, since the inter-wheel area S2 when the frame is deformed is smaller than the inter-wheel area S1 during normal use, the center of gravity stability of the toilet wheelchair 1 is lowered.

  With reference to FIG. 8, the case where the outer peripheral shape of the left frame is deformed by storing the rear side of the left frame in the front side and shortening the length of the left frame will be described. In this case, an interference state can be avoided by storing the rear side of the left frame 81 in the front side after the left rear wheel 72 contacts the toilet bowl 9. However, when the length of the left frame 81 is shortened, the area between the wheels formed by connecting the four wheels is reduced, as in the case where the rear side of the left frame 81 is rotated inward. The stability of the center of gravity of the wheelchair 1 is reduced.

  On the other hand, as shown in FIG. 4, when the outer peripheral shape of the left frame is deformed by rotating the left rear frame 212 outward, the user's foot 61 or footrest 62 is used as the entrance of the toilet room. The toilet wheelchair 1 can reach the upper position of the toilet bowl 9 without being hit.

  Further, the area between the wheels when the left rear frame 212 is rotated outward is an area formed by connecting the four wheels 31, 32, 35 and 34 shown in FIG. The frame can be deformed without reducing the space area, and the stability of the center of gravity when the frame is deformed can be sufficiently secured.

  Therefore, when the outer peripheral shape of the left frame 21 or the right frame 22 is deformed, it is preferable to move the rear side of the left frame or the right frame, and when moving, it is preferable to rotate it outward.

  Next, a mechanism for deforming the outer peripheral shapes of the left frame 21 and the right frame 22 will be described with reference to FIGS. Since the left frame 21 and the right frame 22 are symmetrical and have the same structure, the left frame 21 will be described here.

  As shown in FIG. 9, the left frame 21 has a left front frame 211, a left rear frame 212, and a bent portion 213, and a roller 214 is provided at the rear end portion of the left rear frame 212. . The roller 214 functions as a sliding means for smoothly deforming the left frame 21 along the shape of the toilet without damaging the toilet when abutting on the toilet.

  The roller 214 functions as a push-type switch for operating switching means for switching the movable state of the left frame 21. The movable state of the left frame 21 includes a movable permission state that allows the left frame 21 to move and a movable prohibition state that prohibits the left frame 21 from moving. As shown in FIG. 9, the switching means includes a roller 214, jigs 216A and 216C, a spring 216B, and links 215A, 215B, and 215C. The switching means will be described with reference to FIGS.

  When the roller 214 is pushed and moved in the direction of the bent portion 213, the switching means has a function of removing the tip end portion of the link 215C fitted to the recess 211A provided at the rear end portion of the left front frame 211 from the recess 211A. When the front end of the link 215C is disengaged from the recess 211A, the left rear frame 212 can be rotated about the shaft 218. That is, the switching unit switches the movable state of the left frame 21 from the movable prohibited state to the movable permitted state by removing the tip of the link 215C from the recess 211A.

  On the other hand, when the force that pushes the roller 214 is released, the switching means uses the force that the spring 217 provided on the bearing portion of the shaft 218 returns to the original state before the left rear frame 212 is rotated. The link 215C has a function of fitting the tip of the link 215C into the recess 211A. When the tip of the link 215C fits into the recess 211A, the left rear frame 212 becomes unrotatable. That is, the switching means switches the movable state of the left frame 21 from the movable permission state to the movable prohibition state by fitting the tip of the link 215C into the recess 211A.

  The switching means will be described in more detail with reference to FIGS.

  FIG. 11 is a diagram schematically showing the periphery of the roller 214. FIG. 11A is a diagram in a movable prohibited state, and FIG. 11B is a diagram in a movable permitted state. As shown in FIG. 11A, when the roller 214 is not in contact with the side surface of the toilet 9, the jig 216A that supports the roller 214 is maintained at a predetermined position by the force of the spring 216B.

  As shown in FIG. 11B, when the roller 214 comes into contact with the side surface of the toilet 9 and the force pushing the roller 214 exceeds the force of the spring 216B, the jig 216A supporting the roller 214 is moved to the left rear frame 212. It moves in the direction of the jig 216 </ b> C fixed to the head. When the jig 216A moves, the link 215A having one end fixed to the jig 216A moves in the bent portion 213 direction D1.

  FIG. 12 is a diagram schematically showing the periphery of the link 215B. FIG. 12A is a diagram when the movable state is prohibited, and FIG. 12B is a diagram when the movable state is permitted. As shown in FIG. 12A, when the roller 214 is not pushed and moved, the state of the links 215A, 215B, and 215C maintains the state in which the tip of the link 215C fits into the recess 211A.

  As shown in FIG. 12B, when the roller 214 is pushed and the link 215A moves in the bent portion 213 direction D1, the link 215B to which one end of the link 215A is fixed rotates in the counterclockwise direction D3. A link 215C having one end fixed to the link 215B moves in the roller 214 direction D2.

  FIG. 13 is a diagram schematically showing the periphery of the bent portion 213. FIG. 13A is a diagram in a movable prohibited state, and FIG. 13B is a diagram in a movable permitted state. As shown in FIG. 13A, when the roller 214 is not pushed and moved, the bent portion 213 maintains a state in which the left front frame 211 and the left rear frame 212 are linearly connected.

  As shown in FIG. 13B, when the roller 214 is pushed and the link 215C moves in the roller 214 direction D2, the tip of the link 215C comes off from the recess 211A, and the left rear frame 212 is centered on the shaft 218. It can be turned.

  A stopper 212 </ b> A is provided at the end of the left rear frame 212 on the bent side. The stopper 212 </ b> A prevents the left rear frame 212 from rotating inward about the shaft 218. As a result, the left rear frame 212 can be rotated only outward and not inward with reference to the straight line state with the left front frame 211.

  By providing the switching means described above, when the left frame 21 in the movable prohibited state shown in FIG. 14 (A) comes into contact with the side surface of the toilet 9, the left frame is turned by the switching means as shown in FIG. 14 (B). 21 is switched to the movable permission state, and the left rear frame 212 rotates in the outward direction D4 about the bent portion 213.

  On the other hand, when the left frame 21 in the movable permitted state shown in FIG. 15 (A) is separated from the side surface of the toilet 9, the left frame 21 is switched to the movable prohibited state by the switching means as shown in FIG. 15 (B). The left rear frame 212 cannot be rotated.

  As described above, according to the toilet wheelchair 1 in the embodiment, by providing the frame deforming means that can deform the outer peripheral shape of the frame formed by the left frame 21 and the right frame 22, during normal use as a wheelchair. The distance between the wheels arranged at the four corners of the support frame 20 can be widened to ensure sufficient stability of the center of gravity, and when the toilet is used, the outer peripheral shape of the frame is deformed, so that the narrow toilet at the side entrance Even when entering, the support frame 20 or the wheel 30 and the entrance of the toilet room and the toilet bowl 9 interfere with each other, avoiding an interference state where the toilet wheelchair 1 cannot rotate any more, and the toilet wheelchair 1 is removed. It is possible to reliably reach the upper position of the toilet bowl 9.

  That is, by using the configuration in the present embodiment, the support wheel 20 or the wheel 30 interferes with the entrance of the toilet room and the toilet 9 in the normal use state, and the toilet wheelchair 1 rotates halfway. Even if it is restricted and the toilet wheelchair 1 cannot be moved to the upper position of the toilet bowl 9, it is possible to avoid the interference state and allow the toilet wheelchair 1 to reach the upper position of the toilet bowl. Become. As a result, it is possible to provide a toilet wheelchair with high turnability that can be used for any toilet.
