Abstract:
A locking system for a cart having at least one drawer moveable between an open position and a closed position, the system comprising:a lock mechanism adapted to engage and disengage the drawer on the cart to selectively retain and release the drawer, the lock mechanism having a locked configuration wherein the drawer of the cart may not be opened and having an unlocked configuration wherein the drawer of the cart may be opened; an armature selectively engageable with the lock mechanism, the armature being engaged with the lock mechanism in the locked configuration; a drive mechanism coupled to the armature; a power supply electrically coupled to the drive mechanism to selectively energize the drive mechanism; an input device for receiving an input code from a user, the input device being in electrical communication with the power supply and controlling current from the power supply to the drive mechanism such that current is provided to the drive mechanism to disengage the armature from the lock mechanism when in the locked configuration; and an override device, the override device comprising: a yoke coupled to the armature, whereby actuation of the yoke moves the armature to disengage the lock mechanism and thereby permit the lock mechanism to be operated from the locked configuration to the unlocked configuration, and a key-operated lock coupled to the yoke, whereby operation of the key-operated lock actuates the yoke.
