| 20090206616 | Auto vent stop - 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 the non-movable sash member. This housing includes a cavity with a bottom plate therein. The 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 member and a retracted position, to allow movement of the sliding member. Also within the housing is a spring for biasing the tumbler. The housing has one or more flexible members extending from the end walls of the housing that secure the housing to an opening in a window sash when a portion of the window sash is positioned between the underside of a lip on said housing and the flexible member. | 08-20-2009 |
| 20100011669 | Block and tackle balance assembly with rotatable shoe - A balance assembly for a sliding sash window, where a spring-loaded pulley arrangement is interconnected between the window frame and the window, to counter the weight of the window, and permit ease of opening and closing the window. The spring-loaded pulley arrangement is located within a housing, which also facilitates attachment of the shoe. The shoe of this balance assembly being rotatable between a first and a second position to permit fitting the assembly into the side of the window frame, when the shoe is in the first position, and to permit final installation of the assembly when the shoe in the second position. The shoe is retained in the first and second positions by detents. This rotatable shoe feature permitting installation, of the Balance Assembly of this invention, into a window frame at later stages of the window assembly sequence. | 01-21-2010 |
| 20100037524 | Latch for tiltable sash windows - A latch is provided for use principally on a pivotal sash window of a double-hung sash window assembly. The latch comprises a latch-bolt slidably mounted within and biased relative to a housing, where the housing is mounted to the top rail of the sash window. The latch bolt is connected to a button for manual actuation of the latch bolt. The latch bolt, while maintaining the convenience and utility of a standard short throw latch, is contoured and designed to maintain engagement with the jam after the window has been deformed under high sustained wind loading typically experienced during extreme weather phenomena such as hurricanes and tornados. The engagement is assured in spite of twisting of the latch bolt within the corresponding opening in the jam. | 02-18-2010 |
| 20100038918 | Tilt latch with cantilevered angular extension - A latch is provided for use on a pivotable sash window of a single-hung or double-hung sash window assembly to releasably secure the window to the master frame. The latch comprises a latch-bolt slidably mounted within, and biased relative to a housing. The housing is adapted to be installed into the top rail of the sash window through an opening in the stile and top rail, which has a periphery contoured to match the housing end profile. The latch bolt, while maintaining an aesthetically appealing external appearance, is configured to incorporate a cantilevered member which only becomes visible when biased to an angled position where it maintains engagement of the latch housing with the edge of the top wall of the rail during window deformation resulting from high wind loading. The cantilevered member ensures integrity of the latch installation under high wind load conditions typically experienced during extreme weather phenomena. | 02-18-2010 |
| 20100269292 | Block and tackle window balance device - Disclosed are apparatus for a block and tackle window balance to be incorporated in single and double hung window assemblies. In one embodiment the block and tackle window balance includes an improved pulley system that provides smoother, quieter operation. In another embodiment there are stronger channels for protecting the mechanism. | 10-28-2010 |
| 20100281780 | Window vent stop with flexible side engagement pieces - 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 the non-movable sash member. This housing includes a cavity with a bottom plate therein. The 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 member and a retracted position, to allow movement of the sliding member. Also within the housing is a spring for biasing the tumbler. The housing has one or more flexible members extending from the end walls of the housing that secure the housing to an opening in a window sash when a portion of the window sash is positioned between the underside of a lip on said housing and the flexible member. | 11-11-2010 |
| 20100300000 | Single action vent stop - 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. | 12-02-2010 |
| 20110062727 | Vent stop for wooden and other windows - A vent stop is installed into a window/door to limit travel therein of a sash member, and being particularly adapted to permit ease of its installation, especially into a wooden door/window. The stop incorporates multiple retention means to inhibit the stop's removal, once properly installed. The retention means includes a wedge-shaped protrusion located at a distal end of the stop housing, which engages the wood of the window opening when pivotally installed therein, to secure a first end of the stop. The opposite end of the stop may be redundantly secured. A first means of securing the opposite end may comprise one or more arcuate flanges on housing side walls, flanges being adapted to unidirectional movement so as to permit its movement relative to the window opening during installation, but thereafter deterring counter-pivotal motion that would allow removal of the vent stop. A second means comprises a deformable spring clip. | 03-17-2011 |
| 20110138589 | Sash window and door transportation clip - A clip assembly may safely secure sliding sashes of a window or door during transportation, and, in one embodiment, be comprised of a strap member and a pawl member. The strap member may be comprised of a bumper portion, and a strap portion extending therefrom, where the strap portion may have a plurality of teeth formed within the thickness of the strap. The pawl member may have a pair of sidewalls supported by a top wall and an intermediate wall. The top wall may have a protrusion which includes a plurality of pawl teeth formed to complement the strap teeth, and be located proximate to the intermediate wall. The strap may be introduced through the gap between the top rail of an upper sash and bottom rail of the second sash, to then be inserted into the pawl, and thereby be retained by the respective teeth to secure the sashes. | 06-16-2011 |
