ABSTRACT:
A latch mechanism, which is coupled to a window sash that travels within a window frame, is adapted for being coupled to a pocket brace, which extends across the channel opening of the jamb pocket of the side jamb. The latch mechanism includes a main housing, a bolt, and a tension device. The main housing has a sidewall, which includes one or more sidewall sections which extends around at least a portion of the housing and defines an interior space, and has an opening in said sidewall at one end of said housing. The sidewall forms a channel within the interior space of the main housing having an end that coincides with said opening. The bolt is substantially located within the housing and travels along the channel, and has a first end which is adapted for extending through the opening of the housing and extending into the side jamb of a window frame. A first end of the bolt has a protrusion, which projects in the direction of travel of the window sash within the window frame. A tension device is coupled between the bolt and the main housing for biasing the bolt toward a position where the bolt extends at least partially through the opening. When the window sash travels within the window frame, the protrusion at the first end of said bolt moves between an engaged position and a disengaged position relative to the window frame.
