ABSTRACT:
A universal lock for securing any of a variety of different design window sashes closed against any of a variety of different design window frames. The lock includes a pair of spaced keepers on the window sash, and a tie bar mounted to the window frame and having a pair of rollers thereon. The tie bar is reciprocable along its axis to selectively move the rollers into or out of engagement with the keepers of the closed window sash to selectively lock or release the sash from the frame. A base pivotally mounts a handle member to the window frame. A coupler link is pivotally secured at one end to the handle member and has a flange at the other end pivotally secured to the tie bar. The flange has a narrow portion with a first width adjacent the coupler link and a wide portion with a second width spaced from the coupler link. The tie bar includes an opening with a substantially circular portion having a diameter greater than the first width and less than the second width, and a slot portion wider than the second width. The coupler link is positioned at a non-operational angle relative to the tie bar during assembly to allow passage of the flange wide portion through the tie bar opening slot portion. The flange wide portion thereafter holds the coupler link to the tie bar with the flange narrow portion pivotable within the tie bar opening circular portion during operation (i.e., locking and releasing) pivoting.
