Patent

CA 2618183

A system for lifting a platform includes a frame attached to the platform. The invention has at least one upright member having equally spaced holes longitudinally aligned, with each of the holes having an upper surface and a lower surface. A motor is attached to the frame, and a pinion is driven by the motor. The frame carries the motor and pinion. The pinion has a plurality of equally spaced teeth that radially extend from the pinion. Each tooth has a roller that is freely rotatable about its axis. The rollers roll over the lower surface of the holes when the motor rotates the pinion in a direction to raise or lower the frame and platform. A safety dog is attached to the frame to prevent the platform from falling if a motor were to fail.

Un système permettant de lever une plate-forme comprend un cadre fixé à la plate-forme. L'invention comprend au moins un élément vertical doté d'ouvertures équidistantes et alignées longitudinalement, chaque ouverture comprenant des surfaces supérieure et inférieure. Un moteur est fixé au cadre, et un pignon est entraîné par le moteur. Le cadre porte le moteur et le pignon. Le pignon est doté de plusieurs dents équidistantes qui se prolongent de manière radiale depuis le pignon. Chaque dent est dotée d'un rouleau qui tourne librement autour de son axe. Les rouleaux roulent sur la surface inférieure des ouvertures si le moteur fait tourner le pignon dans une direction pour élever ou abaisser le cadre et la plate-forme. Un crochet de retenu sécuritaire est fixé au cadre pour empêcher la plate-forme de tomber dans le cas d'une défaillance de moteur.
