Patent

CA 2591653

A locking mechanism for a casement window assembly includes a housing adapted to be mounted on the window assembly, an actuator operably connected to the housing and pivotable about a fulcrum, and a linkage member having a first channel and a second channel. The housing has an elongated opening having opposed ends. The actuator includes an actuator body having a first pin and a second pin located thereon. The linkage member is connected to the actuator such that the first pin is received in the first channel and the second pin is received in the second channel. Pivoting the actuator about the fulcrum causes the first pin to move within the first channel and the second pin to move within the second channel, moving the linkage member along the opening, from one end of the opening to the other end of the opening.

La présente invention concerne un mécanisme de vérouillage pour châssis qui comprend un boîtier adapté à être monté sur le châssis, un actionneur opératoirement connecté au boîtier et articulé autour d'un point fixe ainsi qu'un élément de liaison ayant un premier canal et un second canal. Le boîtier comporte une ouverture allongée à deux extrémités opposées. L'actionneur comporte un corps sur lequel se trouvent une première goupille et une seconde goupille. L'élément de liaison est connecté à l'actionneur, de telle sorte que la première goupille s'enclenche dans le premier canal et la seconde goupille, dans le second canal. L'action de pivoter l'actionneur autour du point fixe permet de déplacer la première goupille dans le premier canal et la seconde goupille dans le second canal, ce qui engage l'élément de liaison le long de l'ouverture, d'une extrémité de l'ouverture à l'autre.
