The folding link can be locked to open the canopy to use it and unlocked to fold the canopy so that the canopy may be interlocked with the collapsed wheelchair. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【産業上の利用分野】
この発明は、障害者、高齢者のための折り畳み式車椅子用の天蓋に関する。
【0002】
【従来の技術】
従来の折り畳み式車椅子には、雨避け日除けのための天蓋がなく、使用者は強い日差しや雨を防ぐために、帽子か傘あるいは合羽などを用いて雨や日差しを防ぐ他には方法がなく、不便かつ危険であった。
【0003】
【発明が解決しようとする課題】
車椅子を折り畳む時、同時に連動して天蓋を折り畳むことができ、車椅子を使用する時には、同時に連動して天蓋が広がりかつその状態で固定することができること、ならびに多様な寸法を持つ車椅子に対して、天蓋を簡単に脱着できることが課題であった。
【0004】
【課題を解決するための手段】
左右方向に折り畳むことができる車椅子の左右のフレームに、取り付け金具で固定された左右一対の支柱を設け、それぞれの支柱の上端部に前後方向の水平回転軸を設け、これらの回転軸に、中央部の前端部と後端部で互いに連結された左右一対の天蓋フレームをそれぞれ枢着し、天蓋フレームの前後方向の中間部に、死点を超えてロックできる折れリンクを設けて左右の天蓋フレームを連結し、天蓋フレームを防水布などで覆い、車椅子が使用状態の時には、折れリンクを伸ばした状態でロックさせて天蓋を広げ、車椅子を折り畳む時には折れリンクを畳み、車椅子の折り畳み作動と連動して天蓋も折り畳むことができるように構成する。
【0005】
左右方向に折り畳むことができる車椅子の左右のフレームと、天蓋を保持する左右一対の支柱を互いに固定する場合、形状や寸法の異なる車椅子に対し、天蓋の支柱を固定できる共通の部位は、車椅子を介助者が押すハンドルグリップ部に近い、背当てフレームの上部の屈曲部と、車椅子の後輪下部の後方に伸びている水平パイプ部であり、これらの左右4か所のフレームにそれぞれ金具を取り付けて、天蓋を保持する左右一対の支柱の上下部を固定することが適当である。またこれによって天蓋の高さを調節することもできる。
【0006】
従って、これらのパイプ同士の固定金具は、隣接する2つの異なったパイプの径および相対角度に対応して固定できるように、それぞれのパイプを締め付ける金具同志を互いの角度が自在に設定できるようにしてネジで締め付けるようにする構造とする。
【0007】
なお、天蓋を保持する左右一対の支柱は、車椅子に固定している金具のネジを緩めれば、簡単に上方に引き抜いて取り外すことができるが、支柱の上部固定金具の上方にに差し込み継ぎ手を設けることによって、さらに簡単に脱着することができる。
【0008】
【実施例】
以下、本発明の具体的な実施例について、図面に沿って詳述する。
図1は、本発明の天蓋付き車椅子の使用状態における斜視図である。
図2は、本発明の天蓋付き車椅子の折り畳み状態における斜視図である。
【0009】
左右方向に折り畳むことができる車椅子1の、背当てフレーム上部の屈曲部2および後部車輪の下部の後方に伸びる水平フレーム部3には、天蓋を保持する支柱4が、取付け金具5および6で上下部を固定されており、支柱4の脱着あるいは高さ調節が簡単にできるように、蝶ねじ7および8で締め付けられる。また、支柱4の中間部には、差し込み式の継ぎ手部9が設けられ、上部支柱10が設けられているために、天蓋をさらに簡単に脱着できるようになる。
【0010】
上部支柱10の上部は、前方へ水平に曲げられて回転軸11となり、天蓋を構成する左右一対の天蓋フレーム12に設けられた軸受け部13に回転自在に嵌合される。天蓋フレーム12はまた、前後端で弓形に下方に曲げられ、天蓋周辺フレーム14に両端で結合されている。
【0011】
天蓋周辺フレーム14は、天蓋の前中央部15と後中央部16で互いに回転自在に連結され、天蓋は左右の回転軸11を中心に互いに回転することができるようになっているが、天蓋フレーム12および天蓋周辺フレーム14は、天蓋が最大に開いた時には防水布17が強く張ることによって、下方へは折り畳むことができないため、車椅子1が折り畳まれ、これに連動して支柱4の左右の距離が縮まると、天蓋は図1の開いた状態から図2の折り畳まれた状態へ変化する。
【0012】
天蓋フレーム12の前後方向の中間部には、伸ばした時に死点を超えてロックできる折れリンク18が設けられて左右の天蓋フレームを連結し、折れリンク18をロックさせることによって、天蓋を開いた状態で固定することができ、また折れリンク18のロックを外し、車椅子を折り畳めば、天蓋もこれに連動して折り畳まれることになる。
【発明の効果】
【0013】
上記のように構成することにより、折り畳みおよび脱着が簡単で高さの調節ができ、しかもほとんどの車椅子に適合して取り付けることができる、雨避けあるいは日除けの機能を備えた、安全で快適な天蓋付き車椅子を提供することができる。取り外された天蓋は、そのまま折り畳んで別に収納することができるため、車椅子を車両に乗せて搬送する時にも、天蓋が邪魔になることはない。
また必要に応じて、天蓋周辺フレームに透明の垂れ幕を取り付ければ、かなりの風雨に際しても車椅子を十分使用できる効果がある。

[Industrial applications]
The present invention relates to a canopy for a foldable wheelchair for the disabled and the elderly.
[0002]
[Prior art]
Conventional folding wheelchairs do not have a canopy for sun protection from rain, and users have no other way to prevent rain and sun using a hat, umbrella or a pair of feathers to prevent strong sunshine and rain, Inconvenient and dangerous.
[0003]
[Problems to be solved by the invention]
When the wheelchair is folded, the canopy can be folded together at the same time, and when using the wheelchair, at the same time, the canopy can be spread and fixed in that state, and for wheelchairs with various dimensions, The problem was that the canopy could be easily attached and detached.
[0004]
[Means for Solving the Problems]
On the left and right frames of the wheelchair that can be folded in the left and right direction, a pair of left and right supports fixed with mounting brackets are provided, a horizontal rotation axis in the front and rear direction is provided at the upper end of each support, and these rotation axes are A pair of left and right canopy frames connected to each other at the front end and the rear end of the part are pivotally connected, and a folding link that can be locked beyond the dead point is provided at the middle part in the front and rear direction of the canopy frame, and the left and right canopy frames When the wheelchair is in use, lock the foldable link and extend the canopy.When the wheelchair is folded, fold the foldable link and interlock with the wheelchair folding operation. The canopy can also be folded.
[0005]
When fixing the left and right frames of a wheelchair that can be folded in the left and right direction and a pair of left and right supports that hold the canopy, for wheelchairs with different shapes and dimensions, a common part that can fix the canopy supports is a wheelchair. A bent part at the top of the backrest frame, near the handle grip part pushed by the caregiver, and a horizontal pipe part extending to the rear of the lower part of the rear wheel of the wheelchair. Metal fittings are attached to these four left and right frames. It is appropriate to fix the upper and lower portions of a pair of right and left columns for holding the canopy. This also allows the height of the canopy to be adjusted.
[0006]
Therefore, the metal fittings of these pipes can be fixed to each other so that the metal fittings for tightening the respective pipes can be freely set to each other so that the metal fittings can be fixed corresponding to the diameters and relative angles of two adjacent pipes. And tighten it with screws.
[0007]
In addition, the pair of left and right supports that hold the canopy can be easily pulled out and removed by loosening the screws of the bracket fixed to the wheelchair. By providing, it can be more easily attached and detached.
[0008]
【Example】
Hereinafter, specific examples of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a wheelchair with a canopy of the present invention in use.
FIG. 2 is a perspective view of the wheelchair with a canopy of the present invention in a folded state.
[0009]
In a wheelchair 1 that can be folded in the left-right direction, a bent portion 2 at an upper portion of a backrest frame and a horizontal frame portion 3 extending rearward below a lower portion of a rear wheel are provided with supporting columns 4 for holding a canopy by mounting brackets 5 and 6. The part is fixed and fastened with thumb screws 7 and 8 so that the column 4 can be easily attached and detached or the height can be easily adjusted. In addition, a plug-in joint 9 is provided at an intermediate portion of the support 4 and the upper support 10 is provided, so that the canopy can be more easily attached and detached.
[0010]
The upper part of the upper support 10 is horizontally bent forward to form a rotating shaft 11 and is rotatably fitted to a bearing 13 provided on a pair of left and right canopy frames 12 constituting a canopy. The canopy frame 12 is also bowed downward at the front and rear ends in an arc shape and is joined at both ends to the canopy peripheral frame 14.
[0011]
The canopy peripheral frame 14 is rotatably connected to each other at a front center portion 15 and a rear center portion 16 of the canopy. The canopy can rotate around the left and right rotation shafts 11. When the canopy 12 and the canopy peripheral frame 14 cannot be folded downward due to the strong tension of the waterproof cloth 17 when the canopy is opened to the maximum, the wheelchair 1 is folded, and the left and right distances of the support 4 are linked with this. When retracted, the canopy changes from the open state of FIG. 1 to the folded state of FIG.
[0012]
A folding link 18 is provided at an intermediate portion in the front-rear direction of the canopy frame 12 so as to be able to lock beyond the dead center when the canopy frame 12 is extended. The left and right canopy frames are connected to each other, and the folding link 18 is locked to open the canopy. If the folding link 18 is unlocked and the wheelchair is folded, the canopy will be folded in conjunction with this.
【The invention's effect】
[0013]
With the above construction, a safe and comfortable canopy that can be easily folded and removed, can be adjusted in height, and can be fitted and fitted to most wheelchairs. Wheelchairs can be provided. The removed canopy can be folded and stored separately, so that the canopy does not become an obstacle when carrying the wheelchair in a vehicle.
If a transparent banner is attached to the frame around the canopy as required, there is an effect that the wheelchair can be sufficiently used even in the case of considerable wind and rain.
