The invention relates to a device (1) at a window (2) that comprises a window pane (4) received in a window casement (3) with the casement (3) and the pane (4) receivable in a window frame (5), turnable 180° or more around a pivot bearing (8) and locked to the frame (5) by means of lock plungers (6, 7), which are receivable in guiding grooves (9, 10) in the casement (5). According to the invention, in each corner (A-D) of said frame (5), a control mechanism (11) is arranged for the regulation of the motion of said lock plungers (6, 7). A control (27) for the actuation of said lock plungers (6, 7) is arranged on the window (5) and the control mechanism (11) comprises a cam surface (14) that is co-operatable with a motion transfer part (19) for the lock plungers (6, 7). The window casement (3) is optionally openable at the top or bottom, turnable, angleable into the desired position as well as lockable by the actuation of controls (12 and 13, respectively; 27) therefor.

摘要:
A multipoint lock system for use with the active and inactive doors of two-door sets, which provides an operator with the ability to lock or unlock a plurality of locking points both manually and automatically, and features a blocking mechanism to prevent unwanted locking. The system comprises a pair of releasably engaged mechanisms, one of which primarily controls the deployment of the locking members, while the other primarily controls the receiving windows that receive the locking members. Each mechanism is operated by a lever and thumbturn attached to a centralized cassette.
摘要:
A lock for use as a multipoint lock, the lock having: a lock body, a lock tongue which is moveable between a locking position and a free position, an actuator to move the lock tongue, a deadlocking member in the lock body and which is moveable between a deadlocking position to deadlock the lock tongue and an undeadlocking position, and, attachment means attachable to a remote lock operator to move the operator without any lost motion.

A locking device for a door, window, or the like, has a main lock casing, at least one additional lock casing and at least one pushrod connecting the additional lock casing with the main lock casing. The additional lock casing has a retractable latch bolt, which can be freely pushed out of the latch position into the additional lock casing, which can be pushed into its locking position by means of a spring and/or a gear. The latch bolt on its side located opposite a leading incline and in the area of the latch end has a protrusion, on which a latch restoring lever acts, and the latch restoring lever has a first catch, by means of which a pushrod is taken along in the, and; one direction, a second catch, by means of which it is taken along by the pushrod in the other.
摘要:
A deadlock with a locking bolt having a tongue that is displaceable from a latched position to an unlatched position, the lock including locking means to displace the tongue past the latched position to a locked position. The locking tongue is similarly curved on both sides so that, in use, it slides past a striker plate to the latched position in both right and left hand locking doors. A multi-point deadlock in which a center lock is coupled to at least one auxiliary lock via transmission mesans. The center lock having handles coupled to the latching tongue of the center lock and the transmission means so that downward movement of either handle causes the center lock to unlatch and upward movement of either handle from the horizontal drives the transmission means to effect locking of the auxiliary lock.
摘要:
An interconnecting lock assembly having simultaneously actuated, multiple security deadbolts, the central one forming part of the main lock subassembly, and the others being operated from the main lock subassembly through special mechanism.
摘要:
A latch and lock extension is provided for a round top door, for use in combination with a multipoint latch and lock mechanism of the type disclosed in U.S. Pat. No. 5,290,077. The extension comprises a curved channel for guiding an elongated auxiliary actuator drive bar along a curved path from one side edge of the door where it is coupled with a main drive bar as disclosed in U.S. Pat. No. 5,290,077, to at least one auxiliary latch cartridge disposed generally at the top of the round top door for engaging an associated keeper in the top of the door frame. The auxiliary actuator drive bar is constructed from an assembled plurality of articulating links and a plurality of relatively rigid bridge links to accommodate the size and curved shape of the curved channel.
