CA 2235032

A single point lock or cam lock for a casement window is provided. The lock includes an escutcheon providing a low profile and a smooth uninterrupted surface which faces the inside of the room. The handle includes two opposing legs that enter the escutcheon for attachment to the hook through opposing side walls of the escutcheon. A shaft provides the connection between the hook and the handle which rotates on two brace structures provided by the frame. The frame is sandwiched between the escutcheon and the inside surface of the window frame. The design of the escutcheon, the shaft and the braces of the frame provide for an effective seal against the inside surface of the window frame.

La présente invention a pour objet un dispositif de verrouillage à point unique à came et levier pour fenêtre à battants. Le dispositif en question comporte une plaque-écusson à profil bas qui, située à l'intérieur de la pièce, se caractérise par sa surface lisse et sans discontinuités. La poignée de commande comporte deux pattes opposées qui pénètrent par les côtés opposés de la plaque-écusson pour saisir le crochet de verrouillage. Un axe assure la liaison mécanique entre le crochet et la poignée qui pivote sur les deux bras-supports de la structure. La structure est montée en sandwich entre la plaque-écusson et la surface intérieure du cadre de la fenêtre. La plaque-écusson, l'axe et les bras-supports de la structure sont conçus de manière à assurer l'étanchéité avec la surface intérieure du cadre de la fenêtre.
