Patent

CA 2559930

A fixed plate (15) is provided on a fixed metallic frame (14). An opening/closing metallic frame (17) having a movable plate (21) is movably/closably installed on the fixed metallic frame (14). A pressurizing mechanism (23) is installed on the fixed metallic frame (14) and applies pressing force in a closing direction produced by a spring (25) to the opening/closing metallic frame (17) in a closed state. An operation member (29) is movably installed at a position opposite the pressurizing mechanism (23). Cam surfaces (30d, 32a) are arranged between the operation member (29) and the pressurizing mechanism (23). When the opening/closing metallic frame (17) is being closed, the spring (25) is subjected to effect of the cam surfaces (30d, 32a) caused by the movement of the operation member (29) and deformed by its urging force, and as a result, a pressing force to the opening/closing metallic frame (17) is reinforced.

Une plaque fixe (15) est installée sur un cadre métallique fixe (14). Un cadre métallique d'ouverture/fermeture (17) ayant une plaque amovible (21) est installé de manière amovible et en position fermée sur le cadre métallique fixe (14). Un mécanisme de pressurisation (23) est installé sur le cadre métallique fixe (14) et applique une force de pression en direction de la fermeture, laquelle est produite par un ressort (25) sur le cadre métallique d'ouverture/fermeture (17) en position fermée. Un élément de fonctionnement (29) est installé de manière amovible dans une position opposée par rapport au mécanisme de pressurisation (23). Les surfaces de came (30d, 32a) sont disposées entre l'élément de fonctionnement (29) et le mécanisme de pressurisation (23). Lors de la fermeture du cadre métallique d'ouverture/fermeture (17), le ressort (25) est soumis à un effet des surfaces de came (30d, 32a) causé par le mouvement de l'élément de fonctionnement (29) et il est déformé par l'application de sa force. En conséquence, la force de pression sur le cadre métallique d'ouverture/fermeture (17) est raffermie.
