摘要:
A latch-and-bolt lock with simultaneous actuation of the bolt (10) and of the latch (9) during closure, the latch and the bolt being actuated by elastic means (20, 45) so as to protrude from the lock in order to engage in respective selvages of the jamb, characterized in that it comprises: a sensor (68) for detecting a closed position of a door whereon the lock is fitted, the sensor being movable at right angles to a faceplate (8) of the lock between an external position and an internal position relative to the lock and being retained in the internal position by abutment against the doorjamb; a slider (78) which is guided parallel to the latch; a plate (96) for blocking the bolt, which is guided transversely to the slider; a lever (84) which is articulated to the slider (78) and has a first arm (85) which is operatively associated with the sensor and a second arm (87) which is adapted to assume a position for blocking the latch when the sensor and the latch are inside the lock, a member (89) for the actuation of the plate (96) being arranged on the slider (78) and being such that when the latch, after abutment against the doorjamb, is aligned with the corresponding selvage of the doorjamb, by way of the stroke of the latch for engagement in the selvage, the slider (78) is moved into a position in which the actuation member (89) disengages the plate (96) from the bolt (10) and engages the bolt (10) in the corresponding selvage under the thrust of the elastic means.

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.
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 lock comprises tumblers that are composed of two parts provided with oppositely arranged sets of teeth which can mesh frontally. By means of a combination-changing key, the sets of teeth are arranged according to a new combination which corresponds to the combination of the new actuation key.

The bolt for panic-safe locks is installable in one door of a double door and is operatively associated with a strike lock installable in another door thereof. A flat sliding plate (20) is accommodated in a seat (10) of the bolt (3) and guided, against the biasing action of elastic transmission means (17), at right angles to the sliding direction of the bolt (3). The sliding plate (20) has a lug (30) for abutment against a fixed element (4) of the lock when the bolt (3) is engaged in the strike lock. A slider (35) is guided in the bolt (3) parallel to the sliding direction of the bolt (3) and has a tang (38) protruding frontally from the bolt (3). The slider (35) cooperates with the sliding plate (20) so that when the bolt (3) is engaged within the strike lock, the release action produced on the tang (38) by means of the strike lock causes the slider (35) to move the sliding plate (20) into a position in which the lug (30) does not abut against the fixed element (4), allowing retraction of the bolt (3) into the lock due to the release action.
摘要:
Device for facilitating the opening of two-leaf safety doors in which one leaf is provided with an antipanic lock and the other leaf is provided with an antipanic strike lock (1,101) both of which are actuatable by means of handles, having a movable element (7,107) suitable to act on the lock when the handle of the strike lock is actuated. The device comprises an articulated parallelogram shaped so that, when actuating the handle, during a first rotation angle, the parallelogram acts on said element (7,107) and pushes it against said lock to open it, and, during a second rotation angle, the parallelogram disengages from said element.
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.
