本考案は、ブレーキおよび回転止め付の車輪部材に関する。 The present invention relates to a wheel member having a brake and a rotation stop.
【０００２】[0002]
一般に見られる事務椅子には、脚底部にプラスチック製の車輪が設置され、自 由に回転移動できるようになっている。その車輪構造は、車輪の車輪台に対して 垂直に回転軸が嵌挿され、回転軸上端に椅子の支え脚端部が固定され、車輪台は 回転軸および支え脚に相対して回転し、車輪の回転によって椅子が移動可能にな っている。停止作用を備えた椅子の車輪には、一般に側面にブレーキ板が設置さ れ、このブレーキ板が下に降りることによって、車輪台内に設けられているブレ ーキ体を制御し、回転を停止させる。 Office chairs, which are commonly found, are equipped with plastic wheels at the bottom of the legs so that they can rotate freely. In the wheel structure, a rotating shaft is inserted perpendicularly to the wheel base of the wheel, the end of the supporting leg of the chair is fixed to the upper end of the rotating shaft, and the wheel base rotates relative to the rotating shaft and the supporting leg, The chair can be moved by the rotation of the wheels. In general, a brake plate is installed on the side of the wheel of a chair with a stopping action, and when the brake plate descends, the brake body provided in the wheel base is controlled and rotation is stopped. Let it.

しかしながら、この種のブレーキおよび回転止め付車輪椅子は、ブレーキ板を 下に下げることによって、車輪台内の連動するブレーキ体が車輪を固定停止させ 、車輪の停止によって椅子が移動しないようにするのが目的であるが、車輪台は 回転軸に相対して回転するため、方向固定はできない。そのため車輪の地面への 接触状態が悪く、やはり滑ってしまい、車輪の装着体は容易に移動し、車輪を移 動方向に滑らせる。また使用中、車輪の回転を固定できず、突出した車輪台は地 面でも障害物になるだけである。 However, this type of wheelchair with brakes and detents is designed so that the lowering of the brake plate causes the interlocking brake body in the wheel base to stop the wheels stationary and prevent the chair from moving due to the wheel stops. However, since the wheel base rotates relative to the rotation axis, the direction cannot be fixed. As a result, the wheel is in poor contact with the ground and slips again, and the mounted body of the wheel easily moves, causing the wheel to slide in the moving direction. Also, during use, the rotation of the wheels cannot be fixed, and the protruding wheel base only becomes an obstacle on the ground.
【０００４】 したがって本考案の目的は、ブレーキおよび回転止めが設けられている車輪部 材を提供することにある。 また、本考案の別の目的は、単一の押止板によって、二つのブレーキ部品が稼 働し、同時に車輪および垂直回転軸が停止して定位作用を形成し、車輪を停止さ せ、車輪台を固定して回転させない車輪部材を提供することにある。Accordingly, it is an object of the present invention to provide a wheel member provided with a brake and a detent. Another object of the present invention is that a single pressing plate activates two brake components, and at the same time stops the wheels and the vertical rotation axis to form a localization action, stopping the wheels, and stopping the wheels. An object of the present invention is to provide a wheel member which is fixed and does not rotate.

In addition, a slide table is installed in the storage tank, which is pushed by the tension of the spring and presses the pivot of the retaining section. A fixing pin is attached to the other end of the slide, and is installed in an elongated hole of the wheel base to expose the tip of the pin. At the end of the slide, the above-mentioned concave tank and the engaging convex which is pushed by the tension of another spring are installed. As a result, when double braking is performed by applying pressure to the retaining plate, the pivot rotates, the slide table is pushed by the longitudinal end, and the fixing pin enters and is pressed into the concave groove on the inner ring surface of the wheel stand. The engaging projection is pushed by the tension of the spring and enters the stereotactic concave of the annular convex body of the rotating shaft as the slide table advances. Thereby, it is effective to stereotaxically fix the wheel and the rotating shaft at the same time.
