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.
