Abstract

A closure locking means for the opening of a self-service device, in particular an automatic teller machine includes a locking flap, the outside of which is indented. The locking flap, pivotable about an axis, is positioned behind a projecting upper wall panel and in front of a recessed wall panel. A gap is created when the locking flap is pivoted, and as the flap opens the width of the gap increases, so that any ice formed is broken up or jammed objects are released. A self-locking latch and actuator means for the locking flap uses an actuating lever which is pivotable about an axis. The actuating lever includes a shaped guide slot which is engaged by the actuator means. In a first part of the guide slot, no displacement work is performed by the actuator means, whereas in a second part, which is positioned at an angle to the first part, displacement work is performed to move the lever and locking flap.
