キャスターなどの車輪を固定する、既に知られている車輪用ストッパーは、Ｕ字状に一体成形されたその各脚部がストッパ部材を構成しているので、径の大小異なる車輪への適用範囲が狭いという問題点がある。 The known wheel stopper for fixing a wheel such as a caster has a U-shaped integrally formed leg portion that constitutes a stopper member. There is a problem that it is narrow.

本考案は、従来の車輪用ストッパーの問題点を解決した車輪用ストッパーを提供することを目的とする。 An object of the present invention is to provide a wheel stopper that solves the problems of conventional wheel stoppers.

請求項１の考案は、接地した車輪の前後に食い込む互いに対向した一対のストッパ部材と、前記ストッパ部材の所定の最小相互間隔を以って該ストッパ部材を両端に１個ずつ有し、前記最小相互間隔を広げる向きに前記ストッパ部材を変位可能に支持した針金状または帯状の弾性支持体からなることを特徴とする。 The invention of claim 1 has a pair of opposing stopper members that bite in front of and behind a grounded wheel, and one stopper member at each end with a predetermined minimum distance between the stopper members, and the minimum It is characterized by comprising a wire-like or belt-like elastic support body that supports the stopper member so as to be displaceable in a direction to widen the mutual interval.

本考案によれば、接地した車輪の前後に食い込む一対のストッパ部材を、その相互間隔を変位可能に針金状または帯状の弾性支持体で連結したので、径の大小異なる車輪への適用範囲が広がる効果を奏する。また、その構造及び操作も簡単である。 According to the present invention, the pair of stopper members that bite in front of and behind the grounded wheel are connected by the wire-like or belt-like elastic support so that the distance between them can be displaced, so that the range of application to wheels with different diameters is widened. There is an effect. Also, its structure and operation are simple.

図１は、キャスターなどの比較的小型の車輪１が、車輪用ストッパー２により地面３（床面を含む）に対して暫定的に固定されている状態を示す。
車輪用ストッパー２は、接地した車輪１の前後にそれぞれ食い込む互いに対向したストッパ部材４ａ、４ｂと、ストッパ部材４ａ、４ｂを両端に１個ずつ有する弾性支持体５からなる。 FIG. 1 shows a state in which a relatively small wheel 1 such as a caster is temporarily fixed to a ground surface 3 (including a floor surface) by a wheel stopper 2.
The wheel stopper 2 includes a stopper member 4a and 4b that are opposed to each other before and after the grounded wheel 1, and an elastic support 5 that has one stopper member 4a and 4b at each end.

ストッパ部材４ａ、４ｂは、ゴム材で作られていて、それらの各先端を、接地した車輪１の前後に食い込ませる楔状をなしており、一方、弾性支持体５は、湾曲した弾性針金であって、図２に示すように、ストッパ部材４ａ、４ｂの所定の最小相互間隔ｄを以ってストッパ部材４ａ、４ｂを両端に保持している。ストッパ部材４ａ、４ｂは、最小相互間隔ｄから広がる向きに変位可能である。
最小相互間隔ｄは、車輪用ストッパー２を適用し得る最小車輪の前後にストッパ部材４ａ、４ｂが弾力的に食い込む間隔である。
車輪用ストッパー２を車輪に用いるときは、弾性支持体５を押し広げてストッパ部材４ａ、４ｂを、図１に示すように、車輪１の前後にセットする。 The stopper members 4a and 4b are made of a rubber material and have a wedge shape in which their respective tips bite into the front and rear of the grounded wheel 1, while the elastic support body 5 is a curved elastic wire. As shown in FIG. 2, the stopper members 4a and 4b are held at both ends with a predetermined minimum mutual distance d between the stopper members 4a and 4b. The stopper members 4a and 4b can be displaced in a direction extending from the minimum mutual distance d.
The minimum mutual distance d is an interval at which the stopper members 4a and 4b elastically bite before and after the minimum wheel to which the wheel stopper 2 can be applied.
When the wheel stopper 2 is used for a wheel, the elastic support body 5 is expanded and the stopper members 4a and 4b are set in front of and behind the wheel 1 as shown in FIG.

弾性支持体５の両端部をストッパ部材４ａ、４ｂの側面に差し込むことにより、ストッパ部材４ａ、４ｂは弾性支持体５に固定されるが、弾性支持体５のストッパ部材４ａ、４ｂに差し込まれているストッパ部材取り付け部分に対しストッパ部材４ａ、４ｂを摩擦的に回転自在結合すれば、ストッパ部材４ａ、４ｂが車輪の前後にセットされたとき、それらの底面全域が常に地面に接した状態となる。 The stopper members 4a and 4b are fixed to the elastic support body 5 by inserting both end portions of the elastic support body 5 into the side surfaces of the stopper members 4a and 4b, but are inserted into the stopper members 4a and 4b of the elastic support body 5. If the stopper members 4a and 4b are frictionally and rotatably coupled to the stopper member mounting portion, when the stopper members 4a and 4b are set on the front and rear of the wheel, the entire bottom surface thereof is always in contact with the ground. .

針金状の弾性支持体５の代わりに、帯状の弾性支持体を用いてもよい。
図３は、弾性支持体に帯状の弾性支持体１５を用い、その両端にストッパ部材４ａ、４ｂを固定した実施の形態を示す。 Instead of the wire-like elastic support 5, a belt-like elastic support may be used.
FIG. 3 shows an embodiment in which a belt-like elastic support 15 is used as an elastic support, and stopper members 4a and 4b are fixed to both ends thereof.

弾性支持体５及び１５は、それらの両端から立ち上がった形状になっているが、図４は、湾曲部が手前側に延びた形状の弾性支持体２５を用いた車輪用ストッパーを示す。 The elastic supports 5 and 15 are shaped so as to rise from both ends thereof. FIG. 4 shows a wheel stopper using the elastic support 25 having a shape in which a curved portion extends to the near side.

図５は、弾性支持体３５の中央頂部を一巻きした弾性支持体３５を用いた車輪用ストッパーを示す。 FIG. 5 shows a wheel stopper using the elastic support 35 in which the central top portion of the elastic support 35 is wound once.

本考案において、ストッパ部材対が車輪の前後にセットされた位置から離脱しなければ目的は達せられるので、ストッパ部材の相互間隔を狭める向きにストッパ支持部材を付勢する弾性支持体の弾力は比較的弱くてもよく、また弾性支持体の形状も各図に示す形状に限定されるものではない。ストッパ部材の底面を凹凸面にすれば、ストッパ部材と地面との摩擦力を強くすることができる。 In the present invention, if the stopper member pair does not move away from the position set at the front and rear of the wheel, the purpose can be achieved, so the elasticity of the elastic support that urges the stopper support member in a direction that narrows the distance between the stopper members is compared. The shape of the elastic support is not limited to the shape shown in each drawing. If the bottom surface of the stopper member is an uneven surface, the frictional force between the stopper member and the ground can be increased.
