Patent ID: 6877784

Claim:
A tilt latch assembly for use on a hung window comprising: (a) a lock comprising: (i) a base adapted to be attached to a sash; (ii) a handle rotatably connected to the base, the handle having a first position and a second position; (iii) a tilt latch actuating mechanism connected to the handle wherein the tilt latch actuating mechanism is adapted to receive an extensible member, wherein the tilt latch actuating mechanism is adapted to cause the extensible member to move in a direction toward the lock as the handle is rotated from the first position to the second position; (b) right and left tilt latches each comprising: (i) an housing adapted to be mounted to a window sash; (ii) a slider member slidably received by the housing and having an inside end adapted to be connected to said extensible member and a latch end opposite the inside end, the latch end adapted to engage one or both of a groove in a window frame and a component attached to a window frame, wherein the slider member is slidable in a extending direction and in an opposite nonextending direction; (iii) a trigger member connected to the housing, the trigger member having a button, wherein the button is movable in a pivotal direction substantially perpendicular to the movement of the slider member, the button having a protruding position wherein the button is protruding from the housing and a retracted position wherein the button is nearer the housing than in the protruding position; and (c) said extensible member having a first end and an opposite second end and a middle section between the first and second ends, wherein the first end is attached to the inside end of the slider member of the left tilt latch, wherein the second end is attached to the inside end of the slider member of the right tilt latch, and wherein the middle section is received by the tilt latch actuating mechanism, wherein rotation of the handle from the first position to the second position results in movement of the first and second ends of the extensible member in a direction toward the lock, thereby causing the latch ends to move in their respective nonextending directions and resulting in a force on the trigger members in a direction toward the protruding position, and wherein movement of the trigger members from the protruding position to the retracted position results in a force on each of the slider members in their respective extending directions.
