A vending machine locking arrangement operates electronically by way of an electric motor. In particular, the arrangement is a retrofit of an existing, mechanical-key operated T-bar, which is used to close and lock the machine's doors, to provide an electronic locking system not reliant on the use of a mechanical key. The arrangement substitutes for the conventional barrel lock at the handle-end of the T-bar a small electric motor (e.g. a camera re-wind motor) which acts upon the resident locking piece in the T-bar by, e.g., a cam arrangement. The inventive arrangement also makes use of an existing hole near the locking piece for making an electrical connection to the motor. An alternative embodiment places the motor outside the T-bar, the motor then having its own locking piece in the form of, e.g., a rocker arm engaging with an opening in the T-bar. Also disclosed is a smart-card system for driving the motor to trigger the unlocking process. The smart-card may also be used to download the contents of a reader mounted on the machine, these contents providing information on various access parameters related to the machine, e.g. the number of accesses over a period, the cards not allowed access, the identity of the machine, etc.

1. A vending machine lock arrangement, comprising: a) a lock mechanism; b) a T-bar closure device including an internal bore, a wall having an opening, a locking piece disposed in the bore and slidable along a substantially transverse axis through the opening in the wall of the T-bar device, and
1. A vending machine lock arrangement, comprising: a) a lock mechanism; b) a T-bar closure device including an internal bore, a wall having an opening, a locking piece disposed in the bore and slidable along a substantially transverse axis through the opening in the wall of the T-bar device, and a hand-operated end; c) an electric motor for actuating the lock mechanism and disposed within the bore at the hand-operated end, the motor and the lock mechanism being operatively associated with the T-bar device, the motor having a shaft; d) actuation means connected to the motor shaft for displacement of the locking piece, including a cam member engageable during at least a part of its travel with the locking piece to cause the locking piece to be retracted into the bore; and e) a contact piece by which the motor derives its power, the contact piece being disposed in the bore and slidable along the transverse axis, the contact piece being urged to protrude through the opening in the wall of the T-bar device for contact with a corresponding contact assembly external to the T-bar device. 2. The lock arrangement as claimed in claim 1, wherein the contact piece is constituted by a contact pin forming one pole of a voltage supply to the motor, the other pole being constituted by a chassis return of the T-bar device. 3. The lock arrangement as claimed in claim 1, wherein the motor, the cam member and the contact piece are disposed inside a tubular insert dimensioned to form a push-fit inside the bore. 4. The lock arrangement as claimed in claim 1, wherein the locking piece is constituted by a rocker arm pivoted by a pivot means secured to a chassis of a vending machine, one end of the arm being engageable with the cam member and the other end having an extension substantially transverse to a longitudinal axis of the T-bar device for engagement with the opening in the T-bar device. 5. The lock arrangement as claimed in claim 1, wherein the motor is caused to operate by means of an electrical signal generated in a card reader mounted in a vending machine. 6. The lock arrangement as claimed in claim 5, wherein the card reader is arranged to generate the electrical signal upon validation of a card inserted into the reader.
