Patent

CA 2686342

The invention consists of a caster comprises a yoke having a weight transferring tab and a wheel with groove for receiving the tab.. Preferably, the yoke and wheel are made out of plastic, and in some embodiments two different types of plastic. A tab and groove helps transfer the weight of the load on the castor away from the arms of the yoke and onto the wheel. In a preferred embodiment the plastic wheel is molded so as to include a shaft on either side that snap into receiving holes in the yoke, thus avoiding the need for separate axel and rivets.

L'invention concerne une roulette comprenant un empiècement comportant une patte de transfert de poids et une roue avec une rainure pour recevoir la patte. De préférence, l'empiècement et la roue sont composés de plastique, et dans certains modes de réalisation de deux types de plastique différents. La patte et la rainure contribuent à transférer le poids de la charge sur la roulette loin des bras de l'empiècement et sur la roue. Dans un mode de réalisation préféré, la roue en plastique est moulée de manière à inclure un arbre sur l'un des deux côtés qui s'encliquette dans des trous de réception dans l'empiècement, évitant ainsi d'avoir besoin d'un axe et de rivets distincts.
