ABSTRACT:
A coin operated vending machine, and a latching mechanism suitable therefore, both ideally adapted for employment in "honor system" applications. The vending machine preferably comprises a rigid, metallic housing adapted to be disposed upon a supporting surface and an associated door, preferably hingeably coupled to the housing. Unlocking of the door is facilitated by a latching mechanism in response to insertion of coins by the customer. Preferably the latching mechanism comprises a pivoted latch bolt provided with an orifice adapted to be penetrated by an outwardly biased, solenoid controlled locking plunger. A conventional coin mechanism coupled to a self-contained battery supplies a limited duration electric pulse to actuate the solenoid and withdraw the locking plunger. A shield mechanism biased toward the orifice immediately blocks it after the solenoid is energized. When the door is thereafter opened and closed completing a vend, the shield is reset and the latch bolt is deflected to align the orifice for locking penetration by the plunger.
