Door lock retrofitting method, involves enabling snapping of door latch in door frame under normal condition, and attaching blocking element to sliding surface of door latch, where element prevents snapping of door latch in door frame

摘要

The method involves enabling snapping of a door latch (5) in a door frame under a normal condition using a tapered sliding surface (5a) of the door latch. A blocking element e.g. pin (4), is attached to the sliding surface in a form-fitting, force-fitting or material-connection manner, where the element prevents the snapping of the latch in the frame. A blocking surface (4a) is formed by using the element and located at an angle to a closing plate in a stopper with the frame, where closing force of the door does not cause adjustment of the latch against compressive force.
