An actuator structure for concurrently unlatching a pair (20, 22) of sash tilt latches (24). The actuator structure includes a housing mounted to a sash which slides within a window frame (62), a winder (100) rotatably connected to the housing and extending into an interior of the sash, the winder (100) having a diametral slot (102) therein. The actuator structure further includes a filament (50) slidingly received within the slot (102) with ends (52) of the filament (50) connected to the latches (24). As the winder (100) is rotated in a first direction, the filament coils around the winder to draw the latches (24) inwardly, thereby releasing the sash (20, 22) from the frame (62).

L'invention concerne une structure d'actionneur conçue pour déverrouiller simultanément une paire (20, 22) des verrou (24) empêchant le basculement du châssis. La structure d'actionneur comporte un boîtier monté à un châssis qui glisse dans un encadrement de (62) de fenêtre, un enrouleur (100) raccordé rotatif au boîtier et s'étendant dans le châssis et à l'intérieur de celui-ci, enrouleur (100) percé d'un orifice diamétral. La structure d'actionneur comporte également un filament (50) logé coulissant dans la fente (102), les extrémités (52) du filament (50) étant raccordées aux verrous (24). Lorsque l'enrouleur (100) est mû en rotation dans une première direction, le filament s'enroule autour de l'enrouleur, de sorte qu'il tire les verrous (24) vers l'intérieur, et que le châssis (20, 22) soit dégagé de l'encadrement (62).
