MODULAR FOLDING/SLIDING LATCH SYSTEM WITH SELF-LOCKING AND MULTI-FUNCTIONAL OPERATION

A tilting latch (5") and a sliding shoe (62) are guided between the lateral walls of a frame (60) by moving the transverse shafts of the latch and shoe in respective longitudinal and circumferential grooves (58,59). The circumferential groove is formed for retracting the latch when the system is closed and opened. - 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). Es de aplicación a todo tipo de cerraduras para control de accesos, desde un simple retenedor de puerta hasta cerraduras mecánicas, eléctricas y/o antipánico. Su configuración modular, simplicidad de montaje, reducido espacio y sencilla implantación, aportan sustanciales ventajas. La estructura incluye un bastidor o carcasa (60) entre cuyas paredes laterales se guía el picaporte basculante (5'') y el patín deslizante (62) cuyos ejes transversales juegan en respectivas ranuras (58, 59), una longitudinal (58) para el patín (62) y la otra (59) arqueada para el escamoteo del picaporte (5'') al cierre y para su retracción al variar el ángulo de giro del eje superior cuando se realiza la apertura, previa liberación del bloqueo. El picaporte (5'') es almenado y el cerradero (68) incluye un rebaje (69) correspondiente para función antipalanca. Le système de l'invention est applicable à tout type de fermetures de contrôle d'accès depuis un simple organe de retenue de porte jusqu'à des fermetures mécaniques, électriques et/ou pour issues de secours. Sa configuration modulaire, sa simplicité de montage, l'espace réduit
