|20150052817||Window Lock With Corner Drive And Lock Points Along A Side And The Top Of The Window - A locking system for a casement window that provides a corner drive assembly for transmitting vertical movement of a lock bar along one side of the window frame into horizontal movement of a lock bar disposed along a top of the window frame. Thus, lock points on both the non-hinged side of the window frame as well as the top of the window frame may be provided. The corner drive assembly includes a side plunger that is coupled to the side lock bar and a top plunger that is coupled to a top lock bar. Both side and top keepers are provided to provide lock points along the non-hinged side as well as the top of the window. The system may also be extended with a second corner drive assembly in the second upper corner of the casement window and that may extend down the hinged side of the frame and sash as well.||02-26-2015|
|20130312331||Casement Window Operator with Folding Handle - 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.||11-28-2013|
|20100207403||AUTOMATIC SASH LOCK WITH ROTARY LATCH - 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.||08-19-2010|
|20080250719||Locking System for Windows and Doors - A lock system for casement windows is disclosed which includes a tie bar slidably secured to the flame. The tie bat is secured to a lock handle that is also secured to the flame. The tie bat eliminates the need for rollers riveted to the tie bar by having a first bent section disposed between straight sections and a second bent section disposed between straight sections. All of the straight sections are linearly aligned with one another and at least some of the straight sections of the tie bar are slidably mounted to the flame using conventional guides. The lock system also includes first and second strikers mounted to the sash. The first striker comprising a first ramp that receives a first bent section and the second striker comprising a second ramp that receives a second bent section when the tie bat is slidably moved towards the first and second strikers as the tie bar is moved from an unlocked position to a locked position. Movement of the first and second bent sections along the first and second ramps respectively as the tie bar moves towards the locked position results in the sash and frame being pulled together. A third bent section may be included towards the middle of the tie bar and used to couple the tie bar to the lock handle or actuator.||10-16-2008|
