Abstract
A window vent stop for use in a sash window assembly or a door assembly. The vent stop has a housing to be disposed in a recess in the non-movable sash member. This housing includes a cavity with a bottom plate. The tumbler has at least one pivot for pivotally securing the tumbler to the housing for movement between a fully extended position, a halfway extended position. Also within the housing is a spring for biasing the tumbler. The spring maintains the tumbler in a fully retracted position when the sash is in contact with the tumbler, but automatically resets the tumbler to a full extended position when the sash is removed from the tumbler.
