Abstract

<P>PROBLEM TO BE SOLVED: To provide a shock eliminator of a simple structure buffering load fluctuation of a carrier, a wheelchair or the like and easily coping with difference in level of a road surface. <P>SOLUTION: Column shaped-rubbers are welded on inner faces of a fixed plate and a moving plate keeping a specific interval, and the moving plate is set on a desired position through a shaft, thus smooth measures against difference in level of the road surface is achieved, and the fluctuation of load is easily buffered by applying rubber-specific flexible elasticity. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、車輪の軸受等の圧縮の荷重が作用する個所で使用される緩衝装置に関する。 The present invention relates to a shock absorber used at a place where a compressive load acts, such as a wheel bearing.

従来の台車・車椅子等の車輪受けには緩衝装置を設置しないのが一般的である。     It is common not to install a shock absorber on wheel receivers of conventional carts and wheelchairs.

この従来の方法では、台車・車椅子等の車輪の接地面の凹凸を吸収するのに、前・後輪の径に差を設け、前輪を持ち上げる等で運用しているが、大きな段差の場合は対応できないで急激な荷重位置の変動により転倒する場合もある。
本発明が解決しようとする課題は、従来のこれらの問題点を解消し、しかも荷重・変位量を容易に変更できる緩衝装置を提供することにある。 In this conventional method, in order to absorb the unevenness of the ground contact surface of a wheel such as a carriage or wheelchair, the front and rear wheels are set to have different diameters and are operated by lifting the front wheels. In some cases, the vehicle may fall over due to sudden changes in the load position.
The problem to be solved by the present invention is to provide a shock absorber capable of solving these conventional problems and easily changing the load / displacement amount.

一定間隔を保持した板の内面に円柱状に加工したゴム柱を溶着し、片方の板を固定し、もう片方の板を回転させ生じた変位量をゴムの弾性を応用して吸収することを特徴とする緩衝装置にある。     A rubber column processed into a cylindrical shape is welded to the inner surface of a plate that is kept at a fixed interval, one plate is fixed, and the displacement produced by rotating the other plate is absorbed using the elasticity of rubber. In the shock absorber featured.

以下本発明の実施例を図面に基づいて説明する。
本実施例は、本発明の緩衝装置を車椅子の車輪受けとして使用した例である。 Embodiments of the present invention will be described below with reference to the drawings.
In this embodiment, the shock absorber according to the present invention is used as a wheel receiver for a wheelchair.
