Abstract: 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.

Abstract: 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.

Abstract: An improved shoe for a casement window hinge is disclosed. The hinge has a base with a front end and a rear end and two sides. The base has a ridge on the rear end for securing the base to a track and a tongue extending from one of the sides. The tongue has a plurality of teeth extending from a side of the tongue. A gear wheel is adapted to be rotatably secured to a track. The gear wheel has a plurality of teeth about its circumference which mesh with the teeth on the tongue. The rotation of the gear wheel causes the base of the hinge to move longitudinally in relation to the track.

Abstract: The present invention teaches an improved balance shoe. The improved balance shoe of the present invention comprises a balance shoe housing for retaining a sash in a channel of a window. The housing can have a base section and at least one side section. A pivot member can be employed by the housing. Upon rotation, the pivot member can force at least one side support member into contact with a side wall of a window jamb channel when the window is tilted.

Abstract: An improved balance shoe is described. There is a balance shoe housing, wherein there is a pivot member. The pivot member forces at least one side support member against the interior surfaces of a window jamb channel when said window is tilted. The pivot member comprises a base section having a top surface and a bottom surface, said top surface having at least one pivot member extending therefrom, the pivot member being adapted to force said support member against the interior surface of the window jamb as said pivot member is rotated due to the tilting of the window sash.

Abstract: The present invention is directed to an improved 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 the recess. This housing includes a cavity with a bottom plate therein. Inside the cavity is a tumbler that may be in a retracted position and an extended position. When the tumbler is in an extended position the tumbler has a protruding apex at the top. The tumbler has at least one pivot means for pivotally securing said tumbler to said housing for movement between the extended position and the retracted position. In the extended position the bottom of the tumbler overlies a portion of the second sash to prevent movement of the lower sash past the tumbler. When in a retracted position within said cavity the sash or door can be raised and/or moved past the tumbler without interference. Also within the housing is a spring means for biasing said tumbler into said extended position.
