Window tilt latch system

摘要

A tilt latch system that comprises an actuator movable from a first position to a second position; a lock-out member movable from a retracted position to an extended position upon movement of the actuator from the first position to the second position; and an engagement member movable from an engaged position to a disengaged position upon movement of the actuator from the first position to the second position is provided. The actuator and the engagement member are maintained in the second and disengaged positions, respectively, when the lock-out member is in the extended position. The actuator and the engagement member are automatically biased to the first position and the engaged position, respectively, upon movement of the lock-out member from the extended to the retracted position. The tilt latch system may further comprise a lock-out device and/or be optionally utilized in a modular configuration.

主权项

1. A window in combination with a tilt latch assembly, comprising:
a window frame including an interior side generally opposite an exterior side, a first jamb spaced from and parallel to a second jamb, and a third jamb generally parallel to and spaced from a fourth jamb, each of the first jamb and the second jamb having a longitudinal axis perpendicular to a longitudinal axis of each of the third jamb and the fourth jamb; a sash including a glazing and a sash frame, the sash frame having an interior surface and an exterior surface, first rail generally parallel and spaced from a second rail, and a first stile generally spaced from and parallel to a second stile; wherein the sash is inwardly pivotable about a horizontal axis generally aligned with the second rail between a closed position, wherein the sash is generally parallel to the window frame, and an open position, wherein the sash is disposed at an angle relative to the window frame; wherein the first rail includes an inner surface generally opposite an outer surface, the outer surface facing the interior surface of the window frame when the sash is in the closed position and being spaced a distance from the interior surface of the window frame when the sash is in the open position; and a tilt latch system disposed at least partially within the sash frame and adapted to be placed in a locked state and an unlocked state the tilt latch system comprising:
an actuator disposed proximate to an exposed surface of the first rail and movable in a direction generally parallel to the first stile between a first position and a second position, the actuator having a free end;the first rail including an aperture extending therein from the exposed surface of the first rail in a direction toward the second rail, the actuator moving linearly within the aperture in a vector direction defined by a vector perpendicular to the first rail and the second rail and parallel to the glazing, the free end of the actuator being positioned within the aperture and spaced from the exposed surface of the first rail toward the second rail when the actuator is in the second position and the tilt latch system is in the unlocked state;an engagement mechanism operatively coupled to the actuator, the engagement mechanism configured to move between an extended position, wherein the engagement mechanism is disposed at least partially within the first jamb placing the tilt latch system in the locked state, and a retracted position, wherein the engagement mechanism is removed from the first jamb placing the tilt latch system in the unlocked state; wherein moving the actuator from the first position to the second position operatively moves the engagement mechanism from the extended position to the retracted position, the motion of the engagement mechanism including a component generally perpendicular to the motion of the actuator and generally parallel to the glazing wherein the sash is inwardly pivotable between the closed position and the open position while the actuator is in the second position.
