ABSTRACT:
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.
