Press-button combination lock with buttons forming code

摘要

The buttons (13) have grooves (13d) in different positions. A restoring plate (4) returns to an original position by spring pressure, and a release plate (6) is pre-tensioned in an opening position. A spacer element (8) has an elastic action-point trigger resting against the buttons' side flanks. The buttons have a protuberance or recess (13e) matching the action point, and are diametrically opposite on one side on a level with the release plate. The buttons are staggered in position by the thickness of the release plate and have a segment shaped cavity. The restoring plate has conical holes co-operating with the conical ends of the buttons.
