Patent attributes
A window vent stop for use in a sliding sash window assembly or a sliding door assembly. The vent stop has a housing adapted to be disposed in a recess in a non-movable sash member. This housing includes a cavity with a bottom plate therein. A tumbler has at least one pivot for pivotally securing the tumbler to the housing for movement between an extended position, to prevent movement of the sliding sash member and a retracted position, to allow movement of the sliding sash member. Also within the housing is a spring for biasing the tumbler toward the extended position. The tumbler has a first locking member that contacts a second locking member on a release member when the tumbler is in the retracted position and the first locking member does not contact the second locking member when the tumbler is in the extended position.
