Abstract
An access door locking mechanism for a coin operated apparatus wherein the housing for the apparatus is formed having an opening in a wall portion to provide access to said apparatus. A door is mounted on the housing and is disposed for movement from a releasable position to a secured position relative to the housing wall opening. The door and the housing are each provided with members adapted to interengage upon movement of the door to its secured position for retaining the door in place. The door and housing are further provided with complementary interfitting portions for making the outer surface of the door flush with the outer surface of the housing when the door is in its secured position. The door is further provided with an outwardly projecting irregular shaped portion adapted to receive a wrench having a complementary irregular shaped opening for selectively moving the door between its releasable and secured positions. The mechanism further includes key operated locking means mounted on the housing and having a blocking bar disposed for movement, upon operation of the locking means, to engage with a bracket mounted on the door to prevent movement of the door from its secured position to its releasable position.
