摘要:
A panic bar comprising an elongated box-like body (2), constituted by a profile, having a substantially U-shaped cross-section; a first lever (114) and a second lever (14), which are articulated in the box-like body in contrast with elastic return means (20, 120) and are provided with a first arm and a second arm; a bar (37), being accommodated in the box-like body (2), is articulately coupled to the first arms of the first and second levers (114, 14) and can move between a passive position in which the bar partially protrudes from the box-like body and which is determined by the return of the elastic means by way of the levers, and an active position in which the bar is substantially internal to the box-like body and which is determined by an external pressure applied thereon; the first lever being operatively connected to a closure lock (35); characterized in that the levers (14, 114) are articulately supported on corresponding plates (9, 10) which can be detachably fixed to the opposite ends of the box-like body (2), the plate (10) that supports the first lever (114) having the lock (35) rigidly coupled thereon and having a slider (34) which can slide thereon, actuates the lock, and is controlled by the second arm of the first lever.
摘要:
A device for adjusting the trip mechanism of an electric lock that comprises a latch (12) and a reset plunger (5), the mechanism comprising an electromagnet which is composed of at least one coil (22), which forms a seat inside which a ferromagnetic core (24) is guided, the core being actuated by a spring against a keeper (28) which is pivoted in a rocker-like fashion and a ratchet system (9) for actuating the latch (12), the device further comprising a pivot which is rotatably supported inside the lock and is provided with a cam which is operatively associated with the keeper so as to adjust its position with respect to the ratchet system.
摘要:
The security device (17) is placed in front of a double-pattern lock (1) and is actuated by the double-pattern key (12), which has an additional serration (16) that allows to actuate the device into a position for acting on the lock (1).
摘要:
The electric lock comprises a spring latch (11), a reloading piston (12) and an element (14) which is guided in said casing parallel to said piston. The spring latch (11) comprises a stem (32) which is guided in said sliding element and has an end provided with engagement means (34) for said sliding element (14) which are suitable to pull the spring latch (11) into the casing (1) during the opening step. Spring means (39) act on said spring latch to keep said sliding element in abutment against a fixed stroke limiter (33) at which said spring latch protrudes from said casing (1). The stem (32) connects to the hub (42) of the handle so that actuation of the handle causes retraction of the spring latch (11) in contrast with the action of said spring means (39).
摘要:
An effraction-resistant device for a lock with plate tumblers (18) comprising a casing (1) which slidingly accommodates a bolt (9) whose tang (10) has a rack-like set of teeth (11) for moving the bolt by means of a double-pattern actuation key and a transverse pin (33) for locking the bolt so that it is engaged in openings (30) of the tumblers (18) which are elongated in the direction in which the bolt slides. The openings have, along their longitudinal edges, mutually opposite teeth (31,32) which form passages through which the transverse pin (33) can travel by successive key turns. The tumblers (18) have two slots (26,27) which are elongated at right angles to the tang (10) and are engaged by respective guiding pins (13,39) in order to guide the tumblers (18), in contrast with return springs (38), at right angles to the direction in which the bolt (9) slides. The device is characterized in that one (13) of the guiding pins is fixed and the other one (39) is movable and has opposite ends which are rigidly coupled, with play, in respective seats formed in respective mutually opposite walls of the box-like body, so as to allow movements of the pin in the slots and oscillations of the tumblers in an inclined position; engagement means (45,47) are provided which are adapted to engage the tumblers (18) when they are fraudulently made to oscillate in the inclined position.
