  • Patent number: 5805074
    Abstract: An electronic interlock for locking a file cabinet (10, 100) and for limiting the number of drawers (14, 114) to be accessed at any given time. An input keyboard (20, 120) receives an input code to be compared with a prestored access code. If the codes do not match, an unlock signal is not produced. If the input code matches the access code, a processor (28, 148) renders the storage assembly (10, 110) accessible. The processor (28, 128) will receive a drawer selection number from the input keyboard (20, 120) user and will unlock a lock (16, 116) associated with the selected drawer (14, 114). Sensors (34, 134) sense the position of the drawers (14, 114) and disable the processor (28, 128) when one of the drawers (14, 114) is in the open position.

  • Patent number: 5206637
    Abstract: A removable programming unit (11) is connectable to a controller (40) of an electronic locking system (12) of a storage assembly (14) via a telephone cord (38). The removable programming unit (11) comprises a display (52) and a keyboard (54). Through the removable programming unit (11): new access codes used to gain access to the storage assembly (14) may be programmed into the electronic lock; existing access codes may be modified as to which storage units (18) may be accessed; or existing access codes may be deleted. All existing access codes are stored in the memory (92) of the controller (40). The removable programming unit (11) receives 12 V DC from the connection to the electronic lock (12) via an individual wire of the telephone cord (38).

  • Patent number: 5158347
    Abstract: 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.

  • Patent number: 4552466
    Abstract: A novel air bearing structure prevents destructive bending moments within the top foil. Welds are eliminated by mounting the top bearing foil in the bearing cartridge sleeve without using a spacer block.Tabs or pins at the end of the top bearing foil are restrained by slots or stops formed in the cartridge sleeve. These structural members are free to move in a direction normal to the shaft while being restrained from movement in the direction of shaft rotation.
