IMPROVEMENTS TO MODULAR EVOLUTIVE SYSTEMS FOR USE IN PANIC BARS AND SIMILAR LOCKS

摘要

The invention is suitable for use as a sliding panic bar, in which case it includes a casing (3) bearing a boss, on which a suitably-guided sliding half-bar (2) slides. The invention also includes a stationary half-bar (1) including a configuration enabling electrical installation with different recesses for prewiring and other connections and bearing crenellations for the guided movement and alignment of shuttles (41, 42, 43). The invention further includes rails enabling modular attachment and houses a first supporting element (9) supporting head frames (10, 10') having a double circular sector for the double depression of the latch (5) on the positioning shafts (20. 21) thereof. The latch (5) includes an elevated self-locking member (6, 7, 8) forming a compensating spring balance (M6, M7) and receives a recovery rod (15) which, by means of the groove therein, moves along the shaft (21) of the latch together with a compression spring (M15) and pivots on a shaft (23) of a multifunctional locking lever (12).
