Abstract
A latch mechanism is provided for a window which includes a top section and a bottom section with a surrounding groove therebetween. The groove may be varied in size depending on the particular sash header or base slot rail utilized. Different bottom sections can be employed which have flexible side walls of different heights to increase the versatility of the latch mechanisms. Tilt latch mechanisms can also be manufactured formed of a variety of different materials, with a variety of bottom sections having different side wall heights, some of which may be flexible.

A latch mechanism comprising:
- a housing, a slidable latch contained within said housing, said housing comprising a top section, a bottom section, said bottom section comprising a base, side walls, said side walls attached substantially perpendicularly to said base, said top section comprising a top, an edge, said edge surrounding said top, side walls, said side walls attached substantially perpendicularly to said top inwardly of said top edge, and said top section side walls placed within said bottom section side walls.
A window sash latch mechanism for use in a double-hung window within a frame, the mechanism comprising a latch and a spring, said spring contacting said latch, within a two-piece housing, said housing having a top section attached to a bottom section, said latch mechanism positioned within said housing to prevent sash movement within the frame, said top housing section comprising a substantially planar top, an edge, said edge surrounding said planar top, side walls, said side walls affixed substantially perpendicularly to said planar top interiorly of said top edge, said bottom section comprising a base, bottom side walls, said bottom side walls affixed to said base, said top side walls positioned within said bottom side walls, said top side walls contiguous to said base, said bottom side walls spaced from said top to form a groove on said latch mechanism between said top and said bottom side walls.
A window latch for positioning in a slidable window sash having a header and a pair of header rails, said window latch comprising:
- (a) a top section, said top section comprising a top, an edge, said edge surrounding said top, and a pair of opposing, substantially planar side walls joined perpendicularly to said top, inwardly of said top edge;
- (b) a bottom section, said bottom section comprising a base and a pair of opposing substantially planar side walls being joined perpendicularly to said base, said bottom section side walls having height less than the height of said top section side walls to define a groove between said top and bottom sections, said groove for engaging the header rail of the window sash, said bottom section side walls being pivotable relative to said base to adjust the width of said groove;
- (c) a latch bolt positioned between said top and said bottom sections;
- and
- (d) a spring joined to said latch bolt.
