Title WHEELCHAIR PROVIDED WITH FEET
Abstract

Provided is a wheelchair provided with feet for making it possible to control a plurality of feet in any orientation by a simple manual operation, to cope with slippery road surfaces, soft surfaces, and obstacles, and to move freely. A wheelchair provided with feet is provided with: a wheelchair body (11)

large wheels (2) pivotally supported by the wheelchair body (11) via a large-wheel shaft (12)

a plurality of feet (24) pivotally supported by the large wheels (2) via a rotating shaft (23)

a pulley (31) pivotally supported by the large-wheel shaft (12)

a plurality of pulleys (33) which are pivotally supported by the rotating shaft (23) and to which the feet (24) are secured

a wire (36) for transmitting dynamic force to the plurality of pulleys (33) from the pulley (31) pivotally supported by the large-wheel shaft (12)

and rotating handle (41). The plurality of pulleys (33) are coupled together by the wire (36) so as to have the same angular change as the pulley (31) pivotally supported by the large-wheel shaft (12), and are configured so that the angular change of the pulley (31) can be controlled by a rotating operation of the rotating handle (41) irrespective of the rotation of the large wheel (2).
