CA 2094666

A device which can lock a sash to and unlock a sash from a door or window frame has a composite housing which is partially recessed into the frame and receives a portion of a reciprocable plate member which is coupled to one or more motion receiving elements serving to actually lock or unlock the sash. The housing further carries a handle which is pivotable in the plane of the plate member about an axis extending at right angles to such plane, preferably through an angle of approximately 180°. The plate member has one or more sliders which are reciprocable in one or more elongated grooves provided in one or more internal surfaces of the housing. The motion transmitting connection between the handle and the plate member can include a single part, such as a crank, which is non-rotatably connected to the handle and is pivoted to the plate member. Alternatively, the motion transmitting connection can comprise a crank which is non-rotatably connected with the handle and a link which is articulately connected to and forms with the crank a toggle joint. An end portion of the link is articulately connected to the plate member.

La présente invention vise un dispositif servant à verrouiller un châssis de porte ou de fenêtre sur le cadre de cette fermeture, comportant un boîtier composite partiellement encastré dans le cadre et destiné à recevoir une portion d'un élément plat, à mouvement de va-et-vient, couplé à un ou plusieurs éléments servant à assurer le verrouillage ou le déverrouillage du châssis. Le boîtier comporte également une manette qui pivote dans le même plan que la plaque, autour d'un axe perpendiculaire à ce plan, de préférence à un angle d'environ 180 degrés. La plaque comporte un ou plusieurs coulisseaux qui se déplacent dans une ou plusieurs rainures pratiquées dans une ou plusieurs parois du boîtier. L'élément de transmission du mouvement entre la manette et la plaque peut être constitué d'une pièce unique, comme une bielle, fixée à la manette et pivotant dans le sens de la plaque. Selon une autre variante, l'élément de transmission peut être constitué d'une bielle fixée à la manette, et d'un élément de liaison articulé sur la bielle et formant avec elle une genouillère. Une des portions d'extrémité de l'élément de liaison est articulée sur la plaque.
