Description

図8は車椅子1の前方の両側に軸35を設け、モーター等にて作動するアクチュエーター34を取り付け、車椅子の両側に取り付けた軸29には持ち上げ捍32を軸支し、持ち上げ捍32の内部にモーター28にて作動する歯車27又はスプリング30にてスライドする伸縮捍40を差し込み、下端には弾設するスプリング又はゴム37を介して橇38を取り付け軸29に軸支し、上部をアクチュエーターの伸縮する支点33に軸支する。
前車輪3が段差にて止まると、バッテリー10のスイッチ11を押しアクチュエーター34にて持ち上げ捍32の支点33を押すと、橇38が接地し前車輪3を持ち上げ後車輪2を回して前進し、前車輪3が段差上に上がった時点でアクチュエーター34で支点33を引き寄せ、持ち上げ捍32を戻すと前車輪3が段差上に接地し、後車輪2を回して段差上に上り前進する。
伸縮捍40はワイヤー21をハンドル41にて引き締めて留める。
伸縮捍40の先が車7に変えて橇38になっているため、踏切のレール39の溝上又は圧雪した雪道を滑るように進むことが出来る。
図9ではハンドル41を下げ、伸縮捍40を伸ばしアクチュエーター34にて支点33を押すと、橇38がホーム43に接地し後車輪2を回して前進すると、前車輪3を浮かしたままホームに降りる事が出来る。
図10は図8又は図9からワイヤー21歯車27モーター28スプリング30伸縮捍40ハンドル41を省き持ち上げ捍45に直接橇38を取り付け、ブレーキ44は既存の物を使用し単純化したもので、どのような車椅子にも取り付け可能であり特に前車輪の小さい場合は有効であり、特に10図の車椅子は踏切39や圧雪した雪道46に適する。
In FIG. 8, shafts 35 are provided on both sides in front of the wheelchair 1 and actuators 34 operated by a motor etc. are attached, and lifting rods 32 are pivotally supported on shafts 29 mounted on both sides of the wheelchair. A gear 27 operated by a motor 28 or an elastic rod 40 sliding with a spring 30 is inserted, and at a lower end, a collar 38 is pivotally supported on a mounting shaft 29 via a spring or rubber 37 resiliently mounted Pivotally supported on the fulcrum 33.
When the front wheel 3 stops at the step, when the switch 11 of the battery 10 is pushed and the actuator 34 lifts and the fulcrum 33 of the rod 32 is pressed, the rod 38 contacts the ground, lifts the front wheel 3 and rotates the wheel 2 to move forward. When the front wheel 3 rises above the step, the fulcrum 33 is pulled by the actuator 34, and when the lifting rod 32 is returned, the front wheel 3 comes in contact with the step and turns the rear wheel 2 to advance upward on the step.
The telescopic scissors 40 tighten the wire 21 with the handle 41 and fasten it.
Since the tip of the expansion / contraction rod 40 is changed to a car 7 and becomes a ridge 38, it can travel on a ditch of the rail 39 of the level crossing or on a pressed snow path.
In FIG. 9, when the handle 41 is lowered and the extension rod 40 is extended and the fulcrum 33 is pressed by the actuator 34, the rod 38 comes in contact with the home 43 and rotates the rear wheel 2 to move it forward while leaving the front wheel 3 floating. I can do things.
10 is a wire 21 gear 27 motor 28 spring 30 telescopic lever 40 handle 41 from FIG. 8 or FIG. 9 lifting lever 41 attached directly to the rod 45, brake 44 is a simplified version using existing ones, which Such a wheelchair can be mounted, and is particularly effective when the front wheel is small. Especially, the wheelchair shown in FIG. 10 is suitable for crossings 39 and snowy roads 46.
