ABSTRACT:
A window lock is disclosed for use with a window sash and cooperating frame to retain the sash in position. The sash includes first and second sash members connected at right angles, with the frame including a channel within which the sash is positioned for movement within the frame. The lock includes a latch having an elongated bar and a laterally-extending hook portion, the latch being connected to the second sash member for pivotal movement and extending in a direction normal to sash movement. Pivotal biasing force is applied to the latch in the direction of the hook portion such that the hook portion is normally disposed against an inner surface of the frame channel. An opening defined within the channel receives the hook portion upon positioning of the sash with respect to the frame to align the hook portion and the opening. The hook portion can be locked into engagement with the frame channel. The hook portion can also be locked away from the channel to prevent the hook portion from engaging the opening in the frame as the sash is moved.
