Description
本考案は、車椅子タイヤの屋内上履きに関するものである。 The present invention relates to indoor slippers for wheelchair tires.
屋外を走行してきた車椅子を屋内に乗り入れる際には、車椅子のタイヤに付着している汚れが屋内の床へ付着・拡散しないような措置が求められる。 When a wheelchair that has been running outdoors is put indoors, it is necessary to take measures to prevent dirt adhering to the tires of the wheelchair from adhering to or spreading to the indoor floor.
特許文献１記載の車椅子のタイヤカバーは、車輪に伸縮性の環状ベルトを装着しタイヤカバーとするものであるが、車椅子の後輪のみを対象としている。このため、前輪が屋内に持ち込む汚れを防ぐことができない。 The wheelchair tire cover described in Patent Document 1 is a tire cover in which an elastic annular belt is attached to the wheels, but only the rear wheels of the wheelchair are targeted. Therefore, it is not possible to prevent the front wheels from getting dirty indoors.
特許文献１記載の車椅子のタイヤカバーは、薄膜状の弾性素材の帯を車椅子の後輪に装着するものであるが、車椅子タイヤとの摩擦力が十分にとれず、段差スロープでは車椅子タイヤとタイヤカバーとの間でスリップが生じ、車椅子が前進が出来ないことがある。また、車椅子がその場での１８０度の方向転換したときには、タイヤカバーと床との接地面で捩れが生じ、タイヤカバーが車椅子の車輪から離脱することがある。 The wheelchair tire cover described in Patent Document 1 has a thin elastic band attached to the rear wheel of the wheelchair, but the frictional force with the wheelchair tire cannot be sufficiently taken, and the wheelchair tire and the tire have a step slope. The wheelchair may not be able to move forward due to slippage with the cover. Further, when the wheelchair is turned 180 degrees on the spot, a twist occurs in the contact patch between the tire cover and the floor, and the tire cover may be separated from the wheel of the wheelchair.
本考察は、これまでの環状の弾性素材の帯を車椅子にかぶせるという方式を改め、合成樹脂製の部分円筒チューブを、チューブ形状を維持しようとする素材の弾性を利用して、車椅子タイヤの側面に沿って外縁からはめ込む方式を考案し、この方式により、前輪と後輪のタイヤに同時に、容易に、車椅子タイヤ上履きの装着を可能にするものである。 In this discussion, we changed the conventional method of covering a wheelchair with an annular elastic material band, and made a partial cylindrical tube made of synthetic resin by utilizing the elasticity of the material that tries to maintain the tube shape, and the side surface of the wheelchair tire. A method of fitting from the outer edge is devised along the above, and this method enables the wheelchair tires to be easily attached to the front and rear tires at the same time.
本考案の車椅子タイヤ上履きは、図１に示すように、合成樹脂製チューブ材から断面がＣ型になるように一定幅だけ切り取り去られた、軸方向にフレキシブルに変形する部分円筒形チューブであり、車椅子の前輪および後輪にかぶせ、車椅子の前進とともに押しはめていくことにより、車椅子の前・後輪のタイヤに装着するもので、車椅子タイヤの汚れを庇保する。 As shown in FIG. 1, the wheelchair tire top shoe of the present invention is a partially cylindrical tube that is flexibly deformed in the axial direction and is cut out from a synthetic resin tube material by a certain width so that the cross section becomes C-shaped. , It is attached to the front and rear tires of the wheelchair by covering it on the front and rear wheels of the wheelchair and pushing it in as the wheelchair advances, and keeps the wheelchair tires dirty.
本考案により、車椅子の前輪と後輪のタイヤに、同時に簡単な操作で、車椅子タイヤに上履きを履かせることが容易になる。 According to the present invention, it becomes easy to put slippers on the front and rear tires of a wheelchair with a simple operation at the same time.
車椅子タイヤ上履きを、断面内径が車椅子タイヤの断面外径と同程度の合成樹脂を素材とする部分円筒チューブで形成することにより、部分円筒チューブの弾性力により車椅子タイヤの側面に密着して噛みつき、合成樹脂チューブと車椅子タイヤとの摩擦が大きくなる。このため、車椅子が運行するとき、車椅子タイヤと車椅子上履きとが一体となって回転し、スロープでのスリップや、廻れ右しても車椅子タイヤ上履きが車椅子タイヤから外れることはない。 By forming the wheelchair tire top shoe with a partially cylindrical tube made of synthetic resin whose cross-sectional inner diameter is about the same as the cross-sectional outer diameter of the wheelchair tire, the elastic force of the partial cylindrical tube causes the wheelchair tire to stick to the side surface and bite. The friction between the synthetic resin tube and the wheelchair tire increases. Therefore, when the wheelchair operates, the wheelchair tire and the wheelchair slipper rotate as one, and the wheelchair tire slipper does not come off from the wheelchair tire even if it slips on a slope or turns to the right.
図１に示す車椅子タイヤ上履き１は、軸方向にフレキシブルに変形する部分円筒チューブである合成樹脂製のダクトホースで形成される。 The wheelchair tire slipper 1 shown in FIG. 1 is formed of a duct hose made of synthetic resin, which is a partially cylindrical tube that flexibly deforms in the axial direction.
前記車椅子タイヤ上履き１の部分円筒チューブの断面円周長は、図３に示される車椅子タイヤ７がリム８から露出している部分の円周長とおよそ等しい長さにとられる。 The cross-sectional circumference length of the partial cylindrical tube of the wheelchair tire top shoe 1 is set to be approximately equal to the circumference length of the portion where the wheelchair tire 7 exposed from the rim 8 shown in FIG.
前記車椅子タイヤ上履きは、前輪用と後輪用で異なる長さを持ち、それぞれ図２に示される車椅子の前輪タイヤ３および後輪タイヤ２の外周長に合わせた長さとなっている。 The wheelchair tire slippers have different lengths for the front wheels and the rear wheels, and the lengths match the outer peripheral lengths of the front wheel tires 3 and the rear wheel tires 2 of the wheelchair shown in FIG. 2, respectively.
以下、本考案の車椅子タイヤ上履き１の実施の形態（車椅子の右側車輪への装着例）を図４を用いて説明する。 Hereinafter, an embodiment of the wheelchair tire slipper 1 of the present invention (example of mounting on the right wheel of a wheelchair) will be described with reference to FIG.
図４（ａ）に、前輪用車椅子タイヤ上履き１２の一端１０を、前輪３のキャスターのフォーク６付近の前輪３に、後輪用車椅子上履き１１の一端９を、後輪２の前方接地点付近の後輪２に、はめ込み押し込んだ状態を示す。 In FIG. 4A, one end 10 of the front wheelchair tire slipper 12 is attached to the front wheel 3 near the fork 6 of the caster of the front wheel 3, and one end 9 of the rear wheelchair slipper 11 is placed near the front contact point of the rear wheel 2. The rear wheel 2 is fitted and pushed in.
図４（ｂ）に、後輪を４０ｃｍ程前に進めた状態の図を示す。このとき、前輪３と後輪２の接地点が移動するにつれ、後輪用車椅子タイヤ上履き１１および前輪用車椅子タイヤ上履き１２はタイヤに履き込まれていき、履き込まれた車椅子上履き１は、合成樹脂素材の持つ断面（円周）を小さくしようとする弾性力の作用で、タイヤ側面に密着して装着されている。 FIG. 4B shows a state in which the rear wheels are advanced by about 40 cm. At this time, as the ground contact points of the front wheels 3 and the rear wheels 2 move, the wheelchair tire top shoes 11 for the rear wheels and the wheelchair tire top shoes 12 for the front wheels are worn on the tires, and the wheelchair top shoes 1 worn on the wheels are synthesized. It is mounted in close contact with the side surface of the tire due to the action of elastic force that tries to reduce the cross section (circumference) of the resin material.
図４（ｃ）に、後輪２をほぼ１／２回転させた状態を示す。このとき前輪３は１．５周ほど回転しており、前輪用車椅子タイヤ上履き１２は前輪３にしっかり巻き付いている。後輪２のタイヤには、接地点を通過してきた後輪用車椅子上履き１１が、ほぼ１／２の周にわたって装着されている。残りの１／２は、後輪２の上に被さっている状態であるが、このあと車椅子がさらに１／２回転することにより、車椅子上履き１１は完全に後輪２に巻き付けられる。 FIG. 4C shows a state in which the rear wheel 2 is rotated approximately 1/2. At this time, the front wheel 3 is rotating about 1.5 laps, and the front wheel wheelchair tire slippers 12 are firmly wrapped around the front wheel 3. The tires of the rear wheels 2 are fitted with wheelchair slippers 11 for rear wheels that have passed the ground contact point over approximately half the circumference. The remaining 1/2 is in a state of covering the rear wheel 2, but after that, the wheelchair is further rotated by 1/2, so that the wheelchair slippers 11 are completely wrapped around the rear wheel 2.
