Abstract

A window combination latch (140) includes a sash lock (142) and tilt a latch assembly (230). The sash lock (142) installs on a top rail of a window sash (110) and includes a cam (214) that rotatably couples with a keeper (144) to lock the window sash (110). The cam (214) includes a slot (320). The latch assembly (230) when installed has a tip (422) of a latch bolt (232) adjacent to a surface of a stile (112) of the window sash (110) and a head (412) of the latch bolt (232) engaged in the slot (320). The latch bolt (232) may be a one-piece structure that may include a flexible extension (414).

• E05B 65/08 - Locks for special use for sliding wings
• E05C 3/04 - Fastening devices with bolts moving pivotally or rotatively without latching action with operating handle or equivalent member rigid with the bolt

Abstract

A lock system includes an active panel center gearbox. The active panel center gearbox includes a deadbolt, a deadbolt drive to extend or retract the deadbolt, an upper drive assembly, a lower drive assembly, a latch bolt, a handle assembly to retract the latch bolt and to extend or retract the lower and the upper driver assemblies, a reverse action rocker coupling the lower and the upper drive assemblies so they move in different directions, a mishandling bolt, and a mishandling plate. When the mishandling bolt extends, it lowers the mishandling plate. When the mishandling plate lowers, it engages the deadbolt to prevent the deadbolt from extending, it engages the handle assembly to prevent the lower drive assembly from extending, and it engages the reverse action rocker to prevent the upper drive assembly from extending.

Abstract

An operator for a casement window is disclosed which includes a hub that frictionally receives a spindle. The hub is pivotally connected to a proximal end of a pivoting handle. The hub is disposed within a cavity that extends through the proximal end of the handle and terminates at a back wall. The cavity partially accommodates a biasing element, an actuator and the hub. The biasing element is disposed between the actuator and the back wall and biases the actuator towards the hub. The hub includes at least one open position recess and open position protrusion and the actuator includes a complementary protrusion and a recess wherein the protrusion is received in the at least one open position recess of the hub and the recess of the actuator receives the at least one open position protrusion of the hub when the handle is pivoted to the open position.

Abstract

A latch for a window sash is disclosed. The latch includes a cover with a handle, a chassis, a bolt biased towards an extended position and containing a notch, a plunger biased towards the extended position and containing a guide, a rotary latch, pivotally connected to the chassis, containing a guide slot for receiving the guide and a protrusion biased towards the notch. The latch is operated wherein the bolt is locked in a retracted position when the handle slides the bolt inwardly towards the chassis and the protrusion engages the notch as the rotary latch rotates towards the notch, and wherein the bolt is released to the extended position when the plunger slides inwardly towards the chassis and the protrusion disengages from the notch as the rotary latch rotates away from the notch.
