CA 2036749

A cam (103) and follower (107) are used to move a file cabinet drawer (114) out of the closed position toward the open position. The cam (103) is rotated by a motor (113) via a shaft (123) wherein the cam surface (115) translates the rotational motion of the shaft (123) into the linear movement of the follower (107). The follower (107) is attached to the side of the file cabinet drawer (114) and moves the file cabinet drawer (114) forward enough so a user may open the file cabinet drawer without using handles. A hook (129) is connected to the cam (103) through a flexible stem (131) and locks the follower (107) in place disallowing unauthorized access to the file cabinet drawer (114). The hook (129) rotates along with the cam (103) to unlock the file cabinet drawer (114) when it has been selected for opening. The follower (107) is forced under the hook (129), which will flex at the flexible stem (131), when the file cabinet drawer (114) is returned to the closed position. A controller (110) receives inputs, through a keyboard (141) and determines which file cabinet drawer (114) has been selected to be opened.

Came (103) et prolongateur (107) servant à faire passer un tiroir de classeur (104) de la position fermée à la position ouverte. La came (103) tourne au moyen d'un moteur (113), par le truchement d'un arbre (123), dans lequel la surface (115) de la came transforme le mouvement rotatif de l'arbre (123) en un mouvement linéaire du prolongateur (107). Le prolongateur (107) est fixé sur le côté du tiroir de classeur (114) et fait bouger ce dernier (114) suffisamment vers l'avant pour que l'utilisateur puisse ouvrir le tiroir sans l'aide d'une poignée. Un crochet (129) est relié à la came (103) par une tige flexible (131) et verrouille le prolongateur (107), empêchant ainsi l'accès non autorisé au tiroir de classeur (114). Le crochet (129) tourne avec la came (103) pour déverrouiller le tiroir de classeur (114) lorsqu'on veut ouvrir ce dernier. Le prolongateur (107) est forcé sous le crochet (129), dont la tige flexible plie (131), lorsque le tiroir de classeur (114) est refermé. Un contrôleur (110) reçoit des instructions entrées par clavier (141) et détermine quel tiroir (114) a été sélectionné aux fins d'ouverture.
