Patent

CA 2439025

A louver braking mechanism for use in shutters, used to hold the louvers in place against the moment arm resulting from the weight of the tilt bar urging the louvers to close. The disclosed mechanisms provide a frictional resistance to the louver pivotal movement, which must be overcome by the user in order to reposition the louvers. In a preferred embodiment, the frictional resistance increases as the louver begins to pivot.

L'invention consiste en un frein de lames de persiennes servant a garder les persiennes en place contre le bras à moment, issu du poids de la barre d'inclinaison qui pousse les persiennes à se refermer. Les mécanismes décrits dans la présente divulgation offrent une résistance de frottement au mouvement de pivotement des persiennes que l'utilisateur doit contrer pour mettre celles-ci dans une nouvelle position. Dans un mode de réalisation préféré, la résistance de frottement augmente dès que les persiennes commencent à pivoter.
