An automatic locking brake shoe device for a double sash window is disclosed which is slidably disposed in the guide channel of the window jamb liner. The brake shoe device interconnects with an associated sash through a laterally projecting sash pin. The automatic locking brake shoe device comprises first and second brake shoe members that are pivotally connected for relative pivotal movement. The first member is connected to the window balance mechanism, and the second member includes a locking member that engages the jamb liner when it is rotated to the locking position. A small spring disposed between the first and second members normally urges the second member into the locking position when the sash is removed. The sash pin engages the second member when the sash is in its sliding position causing the small spring to yield and to attract the second member from the locking position.
Cette invention concerne un patin d'équilibrage à verrouillage automatique pour fenêtres à guillotine coulissant dans des canaux de guidage du montant de cadre de fenêtre. Le patin objet de l'invention est raccordé au châssis correspondant au moyen d'une goupille faisant saillie latéralement du montant du châssis. Il comprend un premier et un second éléments articulés l'un à l'autre. Le premier élément est raccordé au mécanisme d'équilibrage de la fenêtre et le second comprend un élément de verrouillage qui prend appui sur le montant du cadre de fenêtre lorsqu'on le fait pivoter en position de verrouillage. Un petit ressort intercalé entre les deux éléments articulés ci-dessus pousse normalement le second élément en position de verrouillage lorsque le châssis est enlevé. La goupille du châssis agit sur le second élément lorsque le châssis coulisse dans son canal de guidage et, en neutralisant le petit ressort, force ce second élément à quitter sa position de verrouillage.
