(57) [Abstract] [Purpose] The present invention allows a large wheel of a wheelchair to be equipped with a hand rim that can be driven only in the forward direction, so that the vehicle can travel forward without releasing the hand rim, enabling efficient driving operation on a slope. To [Structure] In the central portion of the hand rim portion 3 of the present invention, there is a hub portion 5 of a bearing having a one-way clutch, and this hub portion is attached to the central portion of the large wheel 1 of a conventional wheelchair. The hand rim part 3 of the present invention is located near the existing hand rim 2 of the large wheel of the wheelchair, but without contacting each other,
It is also mounted so as not to interfere with the movement of the user's hand.
Description
【0001】[0001]
本考案は、車椅子の駆動装置に関するものである。 The present invention relates to a wheelchair drive device.
【0002】[0002]
車椅子を走行させる場合、使用者の腕力は、左右の大車輪に取り付けられたハ ンドリムを、手で掴んだり離したりを繰り返しながら動力伝達されていた。 When running a wheelchair, the user's arm force is transmitted by repeatedly gripping and releasing the hand rims attached to the large left and right wheels.
【0003】[0003]
特に登坂時にあっては、手を離したときの動力伝達の損失は逃れようもなく、 車椅子用スロープ等の整備がすすんだ今日でも、登坂走行は困難である。従って 、本考案のハンドリム部を手を離すことなく、揺動操作することにより前述の欠 点を解消しようとするものである。 Especially when climbing uphill, the loss of power transmission cannot be escaped when the hand is released, and it is still difficult to climb uphill even today with the improvement of wheelchair ramps. Therefore, it is intended to eliminate the above-mentioned deficiency by swinging the hand rim portion of the present invention without releasing the hand.
【0004】[0004]
本考案は、車椅子の左右の大車輪にとりつけて、一方向クラッチにより前進方 向のみに駆動操作することのできるハンドリムを追加し、そのハンドリムを手を 離すことなく握ったままで操作することにより、効率のよい駆動が可能となった 。 The present invention adds a hand rim that can be attached to the left and right large wheels of a wheelchair and driven and operated only in the forward direction by a one-way clutch. Efficient driving became possible.
【0005】[0005]
本考案のハンドリムを握ったまま、ハンドリムの円周方向に揺動運動を繰り返 すことにより前進方向のみが駆動力となり、車椅子は前進する。 By repeating the swinging motion in the circumferential direction of the hand rim while holding the hand rim of the present invention, only the forward direction becomes a driving force and the wheelchair moves forward.
【0006】[0006]
以下、添付図面に従って一実施例を説明する。1は既存の大車輪であり、2も 既存のハンドリムである。3が本考案のハンドリム部であり、このハンドリム部 3の中心には、4のスポーク部を介して、5のハブ部がある。ハブ部5は一方向 クラッチ構造となっていて、大車輪1の中心部に取り付けられている。 An embodiment will be described below with reference to the accompanying drawings. 1 is an existing large wheel, and 2 is an existing hand rim. 3 is a hand rim portion of the present invention, and at the center of the hand rim portion 3, there is a hub portion 5 through a spoke portion 4. The hub 5 has a one-way clutch structure and is attached to the center of the large wheel 1.
【0007】 本考案のハンドリム部3は、大車輪の既存のハンドリム2近くに位置している が互いに接触することはなく、また使用者の手の動きを妨げることのないように 取り付けられており、通常走行には既存のハンドリム2に握り変えて操作すれば よい。The hand rim portion 3 of the present invention is located near the existing hand rim 2 of the large wheel, but is attached so as not to contact with each other and to prevent the movement of the user's hand. For normal driving, you can change the grip on the existing hand rim 2 and operate it.
【0008】 なお本考案は、既存の大車輪1に、脱着式により取り付ける方法でもよいし、 車椅子製作時より製品に組み込まれた操作機能装置としてもよい。The present invention may be attached to the existing large wheel 1 by a detachable method, or may be an operation function device incorporated in the product when the wheelchair is manufactured.
【0009】[0009]
上述のように、利用者は、本考案ハンドリム部から手を離すことなく前進方向 のみ駆動することができるようになり、効率のよい登坂走行が可能となる。 As described above, the user can drive only in the forward direction without releasing the hand rim portion of the present invention, which enables efficient uphill traveling.
