A locking mechanism includes: a rack member (10), for attachment to a window frame (1), which has an engagement surface (14) including a number of parallel ribs (12) extending along the surface in a first direction and a lock member (50), for attachment to a window sash (2), including an engagement surface (51) having a number of corresponding ribs (52) adapted to engage with at least some of the ribs (12) on said first engagement surface (14). The mechanism includes means (30,80) for maintaining said engagement surfaces (14,51) of said rack member (10) and lock member (50) in overlying relationship and means (15,70) for disengaging said rack member (10) and said lock member (50) by providing relative movement of said rack member and lock member in a direction substantially parallel to said ribs until said first (12) and second (52) plurality of ribs disengage, so as to open and close the window.

A stopper for stopping rotation of a planar element with respect to a frame when the planar element is hinged to the frame, the stopper has a longitudinal axis and comprises: a locking bar having a toothed surface and received within an indentation, an operation handle for moving the locking bar out of the indentation, a locking spring having a locking tooth that is urged into the toothed surface, a releasing lever for releasing the locking tooth from the toothed surface, a retention spring for urging the locking bar into the indentation. A linear movement of the operation handle moves a portion of the locking bar out of the indentation, the locking bar abuts against the frame, and, the locking bar is fixed in its position by means of the locking tooth that is urged against the toothed surface.

A method and device for protecting an article, wherein the security device has belt having a latch mating element. A magnetically actuable locking mechanism has a magnetically actuable latch and a flexible element. The magnetically actuable latch includes a lower surface having at least one protrusion extending there from and adapted to engage with the latch mating element of the belt, and a front surface adjacent the lower surface. The front surface has a lateral notch formed therein. The flexible element biases the magnetically actuable latch and the belt into a locked position. A housing has the magnetically actuable latch disposed therein and housing includes a passageway therein defining a belt pathway configured to slidingly receive the belt therein.

A selvage for a secondary wing of fire doors, of the type comprising a body provided with gears constituted by at least one laminar element (13), with which respective vertically sliding sliders (19) are associated, the sliders engaging in corresponding receptacles, one in the threshold and one in the lintel of the opening where the door is installed, the element being actuated by a panic bar for opening. A ring (25) is centrally pivoted on the bottom of the body and perimetrically with respect to the at least one laminar element (13), a rotation of the ring (25) being associated with the translational motion of the at least one element (13); the ring (25) is provided with a toothed edge (27), proximate to which a pawl-type lever (23) is pivoted, the lever being provided with a tooth (24) that can engage removably the toothed edge (27) by means of the forcing of an elastic means (28), the ring (25) being blocked when the tooth (24) is engaged in the toothed edge (27).

The present invention relates to an operation mechanism (1) adapted for activating a deceleration device (2) for decelerating an opening movement of a door (3). The operation mechanism (1) features a first mode of operation and an second operation mode. In the first mode of operation the operation mechanism (1) allows free rotation of the door (3), when the operation mechanism (1) is loaded by an impulse of the door (3) below a predetermined threshold value. In the second mode of operation when the operation mechanism (1) is loaded by an impulse of the door above the predetermined threshold value the operation mechanism (1) decelerates free rotation of the door (3) by connecting the door (3) to the deceleration device (3) which will then decelerate the acceleration of the door (3).

L'invention a trait à une crémone-serrure pour porte, porte-fenêtre ou analogue, comprenant, logé dans un boîtier (2), un mécanisme de commande (3) comportant, d'une part, des moyens d'actionnement (4) d'au moins une tringle de manoeuvre (5, 5A) et, d'autre part, un élément à clé (12) pour la commande de moyens de blocage (13) de la ou des tringles de manoeuvre (5, 5A) en position de verrouillage. Selon l'invention, ces moyens de blocage (13) consistent en un cliquet de blocage (14) qui, sous l'impulsion de l'élément à clé (12), est conçu apte à coopérer, en position de verrouillage, avec une crémaillère (15) associée directement ou indirectement à la ou les tringles de manoeuvre (5, 5A) pour immobiliser cette ou ces dernières dans la seule direction de déverrouillage. La présente invention concerne le domaine de la quincaillerie du bâtiment.
摘要:
The object of the invention is a motor vehicle door lock, bonnet lock or the like with a rotating latch bolt (2) with a receiving recess (3) for a locking wedge (14) or locking bolt, with a detent surface (6) on a main catch and optionally with a detent surface (6') on an auxiliary catch, with a pivotably mounted detent pawl (7) which is prestressed by a spring member or the like in the direction of engagement, and has a counter detent surface (9) used to engage so as to lock in the main catch or in the auxiliary catch with the detent surface (6) on the rotating latch bolt (2). The detent pawl (7) is preferably in the form of a toggle joint and has a detent lever (10) supporting the counter detent surface (9) and a pivotably mounted support lever (11) which are coupled so as to bend towards each other, via a joint with an articulation axle (13) parallel to the pivoting axle (12) of the support lever (11), and the detent pawl (7) when in the locked position is biassed into the extension position by the action of the resilient force of the spring member (8). Moreover, said motor vehicle door lock is designed in such a way that the detent surface (6) on the rotating latch bolt (2) and the counter detent surface (9) on the detent pawl (7) are divided into a plurality of partial surfaces (14) which are engaged with each other when in the locked position. An independent way of resolving the problem of realising such a mechanism is characterised in that an additional spring member (15) is arranged on the detent pawl (7) and is stressed by an actuation shape (16) associated with the main catch, against the rotating latch bolt (2) while said rotating latch bolt (2) is being pulled over, optionally already before the beginning of said pulling over movement, in such a manner that it acts with spring force upon the detent pawl (7) in the direction of bending.
