摘要:
PROBLEM TO BE SOLVED: To provide a wheelchair which has a foothold attached to a shaft provided on a front frame lower end so as to be brought down and raised, and which allows a user to operate the foothold without bending down.SOLUTION: A roughly L-shaped lever 12 is attached on the outer side near an armrest, an operation part 16 extending upwards and an arm part 17 extending forward with a base part 18 as a center are provided, and a connecting rod 13 extending downward is connected to the distal end of the arm part 17. A hollow shaft 22 of an attaching member 14 at the lower end part of a front frame 11 is fitted into a hole provided on the base part 21 of the foothold. Then, a shaft core 15 is fitted into the hole of the hollow shaft 22, and screws 23a and 23b inserted into the holes provided on the base part 21 of the foothold pass through the holes of the shaft core 15 to connect the shaft core 15 and the foothold base part 21. An arm distal end provided on the shaft core 15 is connected with the lower end of the connecting rod 13, and a notched groove is formed in a circumferential direction on the hollow shaft 22 so that the screws 23a and 23b are rotationally movable.【課題】前フレーム下端に設けた軸に足掛けを倒したり起立したりすることが出来るように取付けた車椅子であって、腰を屈めることなく足掛けを操作することが出来る車椅子の提供。【解決手段】肘掛け付近の外側に略L型のレバー12を取付け、基部18を中心として上方へ延びる操作部16と前方へ延びるアーム部17を有し、アーム部17の先端には下方へ延びる連結棒13が連結し、一方、前フレーム11の下端部の取付け部材14の中空軸22を足掛けの基部21に設けた穴に嵌め、そして中空軸22の穴には軸芯15を嵌めると共に足掛けの基部21に設けた穴に挿通したネジ23a,23bは軸芯15の穴を貫通して該軸芯15と足掛け基部21を連結し、軸芯15に設けたアーム先端は上記連結棒13の下端と連結し、しかも中空軸22には円周方向に切欠き溝を形成してネジ23a、23bが回転移動出来るようにしている。【選択図】図2
