PROBLEM TO BE SOLVED: To provide a wheelchair locking device that facilitates alignment (installing alongside) and prevents displacement of a wheelchair to thereby improve safety, when the wheelchair is connected to a locking installation installed alongside in a freely locking/unlocking manner.SOLUTION: Front and rear legs 11, 12 in a wheelchair body 21b of a wheelchair 2b are chucked with a connecting board 7 comprising a rigid member provided at a side of a bathtub 4. The connecting board 7 includes a base board 71, a pair of clamping pieces 72, 73, a support piece 74, and a clamping dial 75. As shown in A1, the rear leg 12 of the wheelchair 2b is fitted in the clamping piece 72. As shown in A2, the front of the wheelchair 2b is pulled over and the leg 11 is fitted in the inside of the clamping piece 73. As shown in A3, the clamping dial 75 is tightened, so that the legs 11, 12 are held between the clamping pieces 73, 72 and the wheelchair 2b is locked to a sidewall 42 of the bathtub 4. Accordingly, the device facilitates alignment, and can prevent the side toppling and side slipping of the wheelchair 2b to thereby improve safety.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2018,JPO&INPIT【課題】車椅子を、横付けした固定設置物に固定/解放自在に連結するに際し、位置合せ(横付け)が容易であるとともに、車椅子の位置ずれを防止し、安全性を向上する。【解決手段】車椅子2bの車椅子本体21bにおける前後の脚部11,12を、浴槽4側に設けた剛性の部材から成る連結ボード7でチャックする。連結ボード7は、ベースボード71と、一対の挟持片72,73と、支持片74と、締め付けダイヤル75とを備える。A1で示すように車椅子2bの後部の脚部12を挟持片72に嵌め込み、A2で示すように車椅子2bの前部を幅寄せして脚部11を挟持片73の内側に嵌め込み、A3で示すように締め付けダイヤル75を締め付けることで、挟持片73,72間に脚部11,12を抱え込み、浴槽4の側壁42に車椅子2bを固定する。したがって、位置合わせが容易で、かつ車椅子2bの横倒れや横滑りを防止でき、安全性を向上できる。【選択図】図8
