Abstract: The disclosed invention is a dispensing apparatus and method for dispensing product from a vending machine. The invention employs a product vend detector to sense when products are dispensed. A controller compares the occurrences of products actually dispensed to the product depth setting assigned to a product dispensing assembly. When vend-completed signals do not match the assigned product setting, the controller initiates a learning mode to determine the actual product depth of the product dispensing assembly and resets the product depth setting to the correct value. The present invention eliminates the need for manual adjustments and eliminates the need to use additional electromechanical components, such as timing cams and switches that are normally used by prior product dispensing systems.

Abstract: A latching mechanism is disclosed for application in vending machines, or the like. In a preferred embodiment the latching mechanism is of one-piece construction. The latching mechanism comprises a ramp mounted to an outer door of the vending machine and configured such that an inner door of the vending machine remains latched to the outer door when it is pulled away from a dispenser housing to access the refrigerated compartment therein. The ramp preferably comprises a ridge on a horizontal surface thereof. When the inner door is urged against the outer door, it passes over the ridge and comes to rest on the ramp. The ridge deters the inner door from sliding off the ramp and becoming detached from the outer door. An appropriate amount of force applied to separate the two doors causes the inner door to roll over the ridge and swing away from the outer door.
