1. The bolt lock consists of: a bolt rotating on a bearing bush, sliding pins secured in the patent openings of the bolt. It is characterised in that it contains: sliding mechanisms (6), consisting of balls, springs and clamping screws, which regulate the position of the bolt (4) with respect to the back plate (5), and profiled elements (10), secured permanently and symmetrically to the pins. The profiled elements end with catches (18), which slide through the wider radial groove up to the point of contact with the longitudinal groove, and do so when the bolt (4) moves. Behind the point of contact, the radial groove becomes narrower. It also contains blocking blocks, secured to the back plate and equipped with wider radial grooves (14), reaching the point of contact with the longitudinal groove (13). The radial grooves become narrower behind the point of contact. It is also equipped with a rotating bush (2f) with a flange at each end, at the side of the front plate (1) and at that of the bolt (4), inside the connected bushes (2 and 2d). Moreover, it has the profiled element (17), fixed to the back plate on the side of the front plate (1). |
