CLUTCH DEVICE FOR ELECTRIC MORTISE LOCKS WITH ANTI-PANIC FUNCTION

摘要

The invention relates to a clutch device for use in electric mortise locks having an anti-panic function, consisting of: a radial centre rest (5), a radial pin (6), a torsion spring (7), a follower (8) actuating the lock bolt, a supplementary outer follower part (9), an outer washer (10), a supplementary square bar (11) for the outer shaft (2), and a right-angled-U-shaped band-like fork (12). According to the invention, the radial centre rest (5) has a curved/concave front (5b) of identical radius to the central axial hole (8b) in the follower (8) and a thickness that matches the width of a radial notch (8c) in the follower (8), in which the radial centre rest (5) is housed and positioned between the tang of the radial pin (6) and a second end (7c) of a torsion spring (7). The torsion spring is mounted on a torsion shaft (7a) and has a first end (7b) connected to the spindle (4a) of the electric motor (4) and a second end (7c) which extends through a filled lug (5a) of the radial centre rest (5).
