ABSTRACT:
Lock comprising a spring-latch and a bolt, the spring-latch being actuatable against the biasing action of a spring by means of an external lever (knob) or an internal lever (handle), the levers being rotationally rigidly coupled to respective coaxial hubs rotatably supported at the sides of an element for opening the spring-latch which is pivoted coaxially to the hubs and is intermediate thereto; the lock further comprises teeth for pulling the element defined on the hubs, the teeth being able to pull the element only in the direction for opening the spring-latch by actuating one of the levers, a spring for the elastic return of the hubs when the levers are released which acts on tabs of the hubs with the interposition of a block guided tangentially to the hubs; the block can be orientated and is shaped so as to provide abutment only to the tab of the hub to which the inner lever is rigidly coupled.
