Patent attributes
An improved vent stop for use in sliding sash windows or sliding doors. The vent stop has a housing adapted to be disposed in a recess of either a door or window. This housing includes a cavity with a bottom plate therein. Inside the cavity is a tumbler that may be in a retracted position, to allow the sash or door to move, and an extended position to prevent the sash or door from moving. The tumbler may move from the retracted position to the extended position via at least one pivot connection. Also within the housing is a spring for biasing the tumbler into the extended position. The tumbler has a pivot member that has a bottom plate contact surface that contacts a side edge of the bottom plate when the tumbler is in an extended position, thus preventing further travel of the tumbler.
