Vending machine lock with motor controlled slide-bar and hook mechanism and electronic access

摘要

An enhanced slide and hook locking mechanism control system for vending machines and the like that utilizes a reversible motor and worm gear drive that operates the slide and hook mechanism. The worm drive is coupled to the slide through a crankshaft type of interconnection. Or as alternatives, the slide means can be gear driven or it may be connected using push-pull type of cable or rod. An electronic control with a microcomputer interface drives the motor control and the system may be operated by a keypad or a remote wireless control device.

1. A locking system for a cabinet having a door capable of being locked and unlocked to the cabinet and the door capable of movement between an open position and a closed position, the locking system comprising:
a motor having an energized state and a de-energized state, the motor carried by one of either the door or the cabinet, said motor being connected to at least one gear, the at least one gear being disposed to move a slide bar for substantially vertical and substantially linear locking and unlocking engagement with the other of the door or the cabinet, the other of the door or the cabinet in one of a locked position and an unlocked position when the motor is in the energized state, the motor connected to the slide bar through the connection with the at least one gear when the motor is in the energized state and the de-energized state, the slide bar having a slide bar locked position and a slide bar unlocked position, an access means including an access control receiver, and a controller interfaced with the motor for initiating said motor to drive, via the at least one gear, movement of the slide bar between the slide bar locked position and the slide bar unlocked position,wherein,
the motor initiates an unlocking process to move the slide bar from the slide bar locked position to the slide bar unlocked position when an access signal is received, and the motor initiates a locking process to move the slide bar from the slide bar unlocked position to the slide bar locked position when the controller receives a signal to indicate the door is placed in the closed position.
