Automatically closing bar locking barrier

摘要

The barrier comprises a locking plate which is movable via a slide bar (10) by a rotary bolt (14). The locking plate engages under pressure behind a protruding edge of a conical bolt (1), due to a tensile spring (6), or a shank-shaped spring (13).The conical bolt may have a tapering stem (18) and may be fitted in the centre of a bottom sleeve (2). The locking plate may be fitted with a tilting limiter, and a plate spring (12) with an end limiter (17). The entire closure assembly, including the lock plate (15), is located in the closure part.
