Modular folding/sliding latch system with self-locking and multi-functional operation
First Claim
1. - MODULAR FOLDING/SLIDING LATCH SYSTEM WITH SELF-LOCKING AND MULTI-FUNCTIONAL OPERATION, including a sliding shoe on parallel guides of the casing, from which emerges the latch itself with the general shape of cylindrical section, oscillating around an axial shaft and assisted by a spring;
- and a self-locking rocker arm, the sliding shoe being assisted by another spring and linked to a retaining lever for the locking and release of the latch, wherein the tilting latch (5′
, 5″
) possesses in its plane of incidence to the closure, a curvo-convex or slightly broken geometry and a radial connection of small curvature, the connecting surface with the sliding shoe (4′
, 62) having a seat (28) for smoothly and seamlessly coupling with said shoe (4).

Abstract
The invention relates to a modular folding/sliding latch system with self-locking and multi-functional operation, which is intended for any type of access-control lock, from simple door retainers to mechanical, electrical and/or panic locks. The inventive system offers substantial advantages, namely: modular design, simple assembly, reduced size and easy installation. According to the invention, the structure comprises a frame or casing (60), and the tilting latch (5″) and the sliding shoe (62) are guided between the lateral walls of said frame. For said purpose, the transverse shafts of the aforementioned latch and shoe move in respective grooves (58, 59), i.e., a longitudinal groove (58) for the shoe (62), and a curved groove (59) which is used to retract the latch (5″) when the system is being closed, and to retract same when the angle of rotation of the upper shaft is varied when the system is being opened, prior to releasing the lock. The latch (5′) is crenellated and the strike (68) comprises a corresponding anti-lever recess (69).
