Abstract

In a caster which supports a wheel by using via a link 3 a bracket 2 to be fitted to a wheelchair or the like, an end of the link 3 is connected with a rotation axis of the bracket 2 via a rubber member 8 which is twisted and deformed resulting from oscillating motion of the link 3, and the link 3 and the bracket 2 are connected by a hydraulic damper 20 which damps the oscillating motion of the link 3, whereby an oscillation or a shock can be absorbed.

Description

technical field

[0001] The invention relates to a caster wheel for baby carts, wheelchairs, etc., in particular to the improvement of the caster wheel with a buffer mechanism. Background technique

[0002] In the past, as a caster with a cushioning mechanism, the wheel and the body of the wheelchair were connected by a link, and the link was connected to the body side through a rubber bush. The wheel displacement caused by the load change twisted the rubber bush to absorb the impact, or The above-mentioned connecting rod is replaced with a hydraulic buffer, so that the hydraulic buffer has the function of the connecting rod and the function of the hydraulic buffer.

[0003] However, in the case of the rubber bush type, only the torsion of the rubber bush is likely to cause insufficient attenuation after the input shock, and in the case of the hydraulic shock absorber type, since the spring characteristics are constant, the applied load If the shock absorber is extended and ...
