  FIG. 6C shows the reclining nursing wheelchair 100 in a state in which the pair of armrests 124 is rotated toward the back surface of the backrest frame 120 and stored. The armrests 124 cross each other and are stored on the back surface of the backrest frame 120. At this time, the overall width W1 of the wheelchair 100 when the armrest 124 is stored is smaller than the width W3 when the armrest 124 is used.

  As shown in FIGS. 7A and 7B, the footrest frame 130 of the reclining nursing wheelchair 100 of the present embodiment is provided with a flat foot plate 131 for placing a foot so as to be accommodated. The foot plate 131 is supported by the first support shaft 132 and is rotatable about the first support shaft 132. The first support shaft 132 is connected to a second support shaft 133 that extends from the tip of the footrest frame 130. The second support shaft 133 is connected to the footrest frame 130 so as to be rotatable about itself. That is, the foot plate 131 has two pivot shafts, and the foot plate 131 is perpendicular to the ground (with the first support shaft 132 as an axis) from the state of use in FIG. The reclining type nursing wheelchair 100 is in a state when the foot plate 131 is housed (see FIG. 5). The reclining nursing care wheelchair 100 is rotated toward the back of the footrest frame 130 (with the second support shaft 133 as an axis). 7 (b)). In the storage mode, the foot plate 131 is disposed so as to be substantially perpendicular to the ground behind the footrest frame 130. In addition, in order to maintain a use form and a storage form, each support shaft is provided with a stopper, and is configured so that the rotation operation stops at a predetermined position (use position and storage position).

  Hereinafter, the effect of the reclining type care wheelchair 100 of one Embodiment of this invention is demonstrated.

  In the present embodiment, the second lower frame 143 to which the main wheel 162 is attached is curved, and the width of the main wheel 162 is configured to be equal to or less than the full width of the wheelchair, thereby increasing the seatable seat width. Provided is a reclining nursing wheelchair 100 with a reduced overall width while ensuring the limit. By reducing the overall width of the wheelchair 100 as described above, the possibility of the main wheel 162 and the axles coming into contact with the obstacle is reduced particularly when the wheelchair 100 is used in a narrow place. In addition, since the second lower frame 143 that mainly supports the weight of the user is curved, it is possible to absorb an impact when the user is sitting and an impact from the road surface when moving. It is possible to provide a more comfortable sitting comfort to the occupant. And since the magnitude | size of the main wheel 162 is made larger than the front wheel 161 according to the curve of the 2nd lower frame 143, it suppresses impairing the driving | running | working property when a road surface has an unevenness | corrugation. Further, since the second lower frame 143 extends downward from the outer frame frame 140 (that is, from both sides of the seat frame 110), the structure immediately below the seat frame 110 can be simplified, and reclining. This contributes to the simplification of the overall structure of the type nursing wheelchair 100.
