Patent

CA 2629730

The apparatus comprises a gripping-operating unit including a gripping subassembly, a base subassembly for mounting the components of the unit and an operating subassembly. The gripping subassembly includes a gripper, from which, at one of its vertical extremity, a lever, integral with the gripper, extends horizontally. The base subassembly generally includes an elongated body and a positioning-attachment element connected to the latter. The operating subassembly comprises a spring guide block with opposed channels, a helical compression spring, located in one of the channels, and a pushing pin having a tooth like extension. Should the lever act on the pushing pin, the later, via the tooth like extension, operates against the helical compression spring, and simultaneously moves beyond the spring guide bloc. When a lock is used, a subassembly strike-stopper and a lock actuator-stopper deactivator subassembly are included.

L'appareil est constitué d'une unité de préhension et d'actionnement comprenant un sous-ensemble de préhension, un sous-ensemble de base pour le montage des composants de l'unité et un sous-ensemble d'actionnement. Le sous-ensemble de préhension comporte un organe de préhension; un levier se prolonge horizontalement à partir de l'une des extrémités verticales de cet organe, dont il fait partie intégrante. Le sous-ensemble de base comprend généralement un corps allongé et un élément de fixation de positionnement relié à ce corps. Le sous-ensemble d'actionnement comprend un bloc de guidage de ressort avec des rainures opposées, un ressort hélicoïdal de compression placé dans l'une des rainures, ainsi qu'une tige de poussée dotée d'une dent. Lorsque le levier agit sur la tige, celle-ci, grâce à la dent, fait fonctionner le ressort hélicoïdal de compression et se déplace simultanément au-delà du bloc de guidage de ressort. Lorsqu'un verrou est utilisé, un sous-ensemble de butoir de gâche et un sous-ensemble pour désactiver le butoir d'actionnement de verrou sont inclus.
