摘要:
A cylinder lock with flat key (7) insertable in a plug which is supported so that it can rotate within a cylinder (2) and can be locked by means of tumbler pin assembly (12a) which, by inserting the key in the plug, is actuated into the position for rotating the plug, the key (7) having at least one movable element (30) which can move within a respective seat (31) which lies within the plane of the key and, in the key insertion position, cooperates with auxiliary tumbler pin assemblies (19,27); these are adapted to position the movable element so that the plug can rotate inside the cylinder; characterized in that in the key, at the seat, at least one hole (38) is provided through which a respective additional auxiliary tumbler pin assembly can engage a respective notch (37) of the movable element in order to assume a position which allows the rotation of the plug.
摘要:
The lock comprises tumblers (17), each composed of two parts (18,19) that are provided with mutually opposite sets of teeth (24,25) that can be coupled to each other frontally. By means of a change key (C,C1), the sets of teeth (24,25) are arranged according to a new combination that matches the combination of the new actuation key.
摘要:
Device for locking the bolts actuated by the strike lock in a two-wing emergency door including a casing (1) adapted to be arranged in a seat of the upper edge of the wing on which the strike lock is applied; the casing (1) is provided with a hole (11) for the passage of the bolt (12), and a sensor (14) is slideable in the casing; the sensor (14) is loaded by a spring (26) and has an end which is meant to cooperate with the lintel (28) of the walled frame of the door and has a chamfer (25); in the sensor there is a pin (20) which is movable transversely and the opposite ends whereof engage slots (21, 22) of the casing (1) which are shaped so as to lock the bolt (12) in retracted position when the sensor (14) is pushed out of the casing (1) by virtue of the action of the spring (26).
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.

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:
Luminous indication system for electric locks, characterized in that it comprises a circuit (2) connected in series to an alternating supply voltage, suitable to allow the predominantly unidirectional flow of the current and to generate a constant voltage at its ends during said flow, the coil (6) of the electromagnet and a first rectifier diode (8), said circuit (2) comprising a diode (3) which is biased inversely with respect to said first rectifier diode (8), and furthermore characterized in that a local pushbutton (7) is arranged in parallel to said first rectifier diode (8), whereas a series connection of a second rectifier diode (10), of a luminous indicator (11) and of a semiconductor component (13) for controlling said luminous indicator (11) is arranged in parallel to said coil (6) and to said first rectifier diode (8), said semiconductor component (13) being driven by an oscillator (14) which is connected to said second rectifier diode (10) through a contact (17), said contact (17) opens when the door containing the electric lock is in a closed position.
摘要:
The cylinder lock and key comprises at least two auxiliary pins (10,11) which are arranged or opposite sides with respect to the key slot (4) and have an end which protrudes into the slot (4). The opposite ends of the two auxiliary pins (10,11) cooperate with respective auxiliary tumbler pins (25,26) which are actuated by springs (27,28) and are suitable for being actuated in the position for rotation of the plug (3) by a lever (17) articulated in an opening (18) of the shank of the key (5) when the key (5) is fully inserted in the lock.
