ABSTRACT:
A releasable locking mechanism for maintaining the door of a merchandising machine in an open position for loading or servicing. Respective link arms pivotally interconnected at one end are pivotally coupled at their other ends to the door and to the cabinet for movement to an aligned position limiting further movement of the door away from the cabinet. A spring biases one of the arms from its aligned position against a stop to provide an automatic locking action, while an extension of the link arm coupled to the door permits ready kick release of the arms from their locking position.
