Patent

CA 2321693

A friction window hinge comprises a frame plate (15) for attachment to the fixed window frame (12), a vent plate (27) for attachment to the movable window vent (11), and a separate curved link (19) which extends between the plates and is slideably engageable with correspondingly curved guide tracks (17, 28) on both of the plates. In the open position the curved link (19) is extended between the plates (15, 27) to support the window vent, while in the closed position the plates are brought into overlying relation with the link retracted between them. The arrangement allows the vent to be swung to the fully open position without the hinged side of the vent significantly obstructing access through the aperture in the fixed frame.

L'invention concerne une charnière à friction pour fenêtre, comprenant une plaque de cadre (15) permettant de fixer le bâti (12) fixe de fenêtre, une plaque (27) pour battant (11) destinée à être fixée au battant (11) d'une fenêtre mobile, et une liaison (19) incurvée, séparée, qui s'étend entre les plaques, et coopère de manière coulissante avec les chemins de guidage (17, 28) incurvés des deux plaques. En position ouverte, la liaison incurvée (19) s'étend entre les plaques (15, 27) de manière à soutenir le battant, alors qu'en position fermée les plaques sont amenées en position de recouvrement, la liaison étant rétractée entre lesdites plaques. L'agencement permet de faire pivoter le battant en position complètement ouverte sans que le côté articulé dudit battant empêche l'accès, de manière significative, à l'ouverture du bâti fixe.
