Abstract

PROBLEM TO BE SOLVED: To solve the problem that there are people, among users, with the habit of rotating a tire of a rear wheel in front of a hand rim and dirt on the tire which rolls on a floor is stuck to a hand of the user, while a self-propelled type wheelchair is moved forward or backward generally by having a user rotate the hand rim of the rear wheel with a hand.SOLUTION: By attaching a displaceable cover on a tire, even when the tire is rotated with a hand, the hand is prevented from getting dirty.

Description

この発明は、自走式車椅子において、利用者自身が手で動かす車椅子に関する。  The present invention relates to a wheelchair that a user himself / herself moves by hand in a self-propelled wheelchair.

歩行等が不自由な状態にある利用者の移動手段として、車椅子が使用されている。
自走式は利用者が、手で後車輪のハンドリムを回転させる。A wheelchair is used as a means for moving a user who is in a state of being unable to walk.
In the self-propelled type, the user rotates the hand rim of the rear wheel by hand.

特開平１０−１２７６９８号公報JP-A-10-127698 特開２００１−８７３２１号公報JP 2001-87321 A 特許第３５５１２５６号Japanese Patent No. 3551256 登録実用新案 第３１０８２２５号Registered Utility Model No. 3108225

しかしながら、利用者によっては心身の能力が落ちているので、手でハンドリム５を回さずに、近くにある後輪のタイヤ４を直に回す人も少なからずある。タイヤは床の汚物を付着しているので、これが利用者の手に再付着して不潔になっている。あるいはハンドリムに手が届いても、手前の汚れたタイヤ４にも手や衣服が触れてしまうことも多い。
利用者が手袋により手の汚れを防ぐことも考えられるが、手袋の着脱を利用者自身ではできないことが多いので介助者が必要になる上、手袋を利用者に装着させることもそう簡単ではない場合が多い。
そこで本発明は、どうしてもタイヤに手を触れてしまう利用者に対して、従来の自走式車椅子に簡単に取り付けられるカバーを介して、タイヤを掴んで駆動することにより、手を汚さないで済むようにすることを課題とする。However, depending on the user, the mental and physical ability is reduced, so there are not a few people who directly turn the rear wheel tire 4 directly without turning the hand rim 5 by hand. Since the tires have dirt on the floor, they re-attach to the user's hands and become dirty. Alternatively, even if the hand reaches the hand rim, the hand and clothes often touch the dirty tire 4 in front.
Although it may be possible for the user to prevent his hands from getting dirty with gloves, it is often not possible for the user himself to attach and detach the glove, so an assistant is required and it is not easy for the user to wear the glove. There are many cases.
Therefore, the present invention prevents the user from touching the tire by gripping and driving the tire through a cover that can be easily attached to a conventional self-propelled wheelchair. The challenge is to do so.

先行の特許文献１は、後輪タイヤの上に可動カバーを配し、カバーは後輪の車軸に乗ったフレームに取り付けられている。構造が複雑で、ハンドリムで後輪を駆動することを想定した通常の車椅子に取り付けられず、車椅子の改造が必要である。
特許文献２〜４は、タイヤの上の可動カバーはやはり車軸に設けており、これも構造が複雑で、通常の車椅子に追加取り付けするには車軸の形状まで変更する大改造が必要である。In Patent Document 1, a movable cover is disposed on a rear tire, and the cover is attached to a frame riding on the axle of the rear wheel. The structure is complicated and the wheelchair cannot be attached to a normal wheelchair that is supposed to drive the rear wheel with a hand rim, and the wheelchair needs to be modified.
In Patent Documents 2 to 4, the movable cover on the tire is also provided on the axle, which is also complicated in structure, and to be additionally attached to a normal wheelchair, a large remodeling is required to change the shape of the axle.

以上の課題を解決するために、利用者が手を触れやすい後輪のタイヤ４の上部に、変位可能なカバー部１を簡単に取り付けられるようにした。  In order to solve the above problems, the displaceable cover portion 1 can be easily attached to the upper portion of the rear wheel tire 4 that is easy for the user to touch.

カバーが変位可能ならば、タイヤを回す癖がついている利用者も、カバーの上からタイヤに触れて、タイヤを回すことができる。タイヤを前後に動かすと変位可能なカバーも同時に動くが、連続して車椅子を漕ぐために手を戻す間に、カバーは元に戻る。
この方法によれば、ハンドリムでなく後輪のタイヤを回す癖がついている利用者の手を汚す事がない。
また正規にハンドリムを回すことができる利用者にも、カバーを外すことなく使ってもらうことができる上、万一袖口がタイヤに触れた場合もその汚染を防止できる。
本カバーは、従来の市販の自走式車椅子に取り外しが簡単にできるので、正規にハンドリムを回すことができる利用者はカバーを取り付けることなく、同じ車椅子を使うことができる。If the cover is displaceable, a user who has a habit of turning the tire can touch the tire from the top of the cover and turn the tire. Moving the tire back and forth moves the displaceable cover at the same time, but the cover returns to its original position while returning the hand to row the wheelchair continuously.
According to this method, the user's hand that has a bag for turning the rear tire instead of the hand rim is not soiled.
In addition, users who can turn the hand rim can be used without removing the cover, and contamination can be prevented even if the cuffs touch the tire.
Since this cover can be easily removed from a conventional commercial self-propelled wheelchair, a user who can properly turn the hand rim can use the same wheelchair without attaching the cover.

この発明の一実施形態を示す概観図である。It is a general-view figure which shows one Embodiment of this invention. カバーを通常の車椅子に取り付ける実施例を示す正面・側面図である。It is a front and side view which shows the Example which attaches a cover to a normal wheelchair. カバーを通常の車椅子に取り付ける他の実施例を示す正面図である。It is a front view which shows the other Example which attaches a cover to a normal wheelchair.

この発明の一実施形態を図１に示す。利用者が後輪を回すときに手を動かす範囲に亘って、後輪タイヤ４の上部にカバー部１を、左右の車輪上部に勝手反対に設ける。
カバー部は、通常の自走式車椅子のフレーム３を利用して取り付ける。フレームは、利用者の両サイドのアームレスト取り付け部付近から、前輪キャスターと後輪を結ぶフレーム付近まで、本カバー部を後付けできる部分を指す。後輪タイヤを圧迫して回転を止める手動ブレーキ部分にカバー部が掛かる場合は、ブレーキとタイヤの間にカバー部を通し、ブレーキより下のフレームに下部カバー取り付け部を設置する。図２、図３に示す実施例は、いずれも上部カバーの取り付け部１ａを例として示しているが、下部のカバー取り付け部１ｂも、上部のカバー取り付け部と同じ構造である。
図２の例は、車椅子のフレーム３にクランプ１ｃを介してバネ１ｆを一体に取り付け、このバネにカバーのシート部１ｄを取り付けている。クランプ方法は、二つ割れの材料をボルト・ナットなどで締結したり、樹脂材料などの弾力性を利用してフレーム３に嵌め込む方式でもよい。
カバーは伸縮変位可能な材料で構成する。例えばジャージやニットなどの布や、ゴムなどの弾力性材料がある。またバネ１ｆのみで充分な変位が得られれば、カバーのシート部は伸縮しない材料でもよい。カバーがタイヤと接触して汚れた部分は、カバーを取り外し、ときどき清掃または洗濯をして、清潔に使用する事ができる。One embodiment of the present invention is shown in FIG. The cover portion 1 is provided on the upper portion of the rear wheel tire 4 and the upper portions of the left and right wheels are opposed to each other over a range in which the user moves his hand when turning the rear wheel.
The cover is attached using the frame 3 of a normal self-propelled wheelchair. The frame refers to a portion where the cover portion can be retrofitted from the vicinity of the armrest attachment portion on both sides of the user to the vicinity of the frame connecting the front wheel caster and the rear wheel. When the cover part is applied to the manual brake part that stops the rotation by pressing the rear wheel tire, the cover part is passed between the brake and the tire, and the lower cover attaching part is installed on the frame below the brake. 2 and 3 show the upper cover attaching portion 1a as an example, but the lower cover attaching portion 1b has the same structure as the upper cover attaching portion.
In the example of FIG. 2, a spring 1f is integrally attached to a wheelchair frame 3 via a clamp 1c, and a cover seat 1d is attached to the spring. The clamping method may be a method in which a material that is split in two is fastened with bolts and nuts, or is fitted into the frame 3 using elasticity such as a resin material.
The cover is made of a material that can be expanded and contracted. For example, there are cloths such as jerseys and knits, and elastic materials such as rubber. Further, as long as sufficient displacement can be obtained with only the spring 1f, the sheet portion of the cover may be made of a material that does not stretch. If the cover is contaminated with the tire, it can be used cleanly by removing the cover and cleaning or washing occasionally.

この実施形態によれば、カバー部を介してタイヤを手で回す際に、バネはカバーのシート部に引っ張られて先端が撓み、カバーのシートが伸縮性材料の場合は相俟って変位し、手でタイヤを押したり引いたりして正逆回転させることができる。  According to this embodiment, when turning the tire by hand through the cover part, the spring is pulled by the cover sheet part and the tip is bent, and when the cover sheet is an elastic material, the spring is displaced together. The tires can be rotated forward and backward by pushing and pulling the tires by hand.

図３は他の実施例で、クランプ１ｃにカバー取り付けロッド１ｇをハングさせ、ロッドには伸縮ゴムまたはスプリング１ｅを介してカバーを取り付ける。
図示しないが、伸縮ゴムまたはスプリングの代わりに、ゼンマイのような渦巻状バネの伸縮を利用してもよい。この場合の実施態様は、巻尺を引き出した後、再び収納するとき、自動的に再び巻き取られていく機構となる。FIG. 3 shows another embodiment, in which a cover mounting rod 1g is hung on the clamp 1c, and a cover is attached to the rod via an elastic rubber or a spring 1e.
Although not shown, instead of the elastic rubber or spring, expansion and contraction of a spiral spring such as a spring may be used. In this embodiment, when the tape measure is pulled out and then stored again, it is automatically wound up again.
