<p>There is disclosed a spring-latch door lock, which can be used particularly on doors to be locked in the closed condition, without the need of using a further lock either of the lever or of the cylinder type. More specifically the lock according to the present invention is characterized in that it comprises a spring-latch member rotatably coupled to a sliding block said spring-latch member being effective to assume two fixed positions with respect to the block. The sliding of said block, in particular, depends on the position of a rotating member able of restraining, or not, the displacement of a suitable shaped lug extending from the inner face of the block and driven by a lever arm in turn driven by a handle.</p> |
