Abstract:
An operator assembly may move a window vent relative to a frame. The operator assembly includes a stationary member, an arm and a drive member. The arm is mounted for rotation relative to the stationary member between an open position and a closed position. The drive member is received in a channel defined by the stationary member for linear motion therein relative to the stationary member and the arm among a first position in which the drive member engages a locking feature of the window vent, a second position in which the drive member is spaced apart from and disengaged from the locking feature without rotating the arm out of the closed position, and a third position in which the drive member is further spaced apart from the locking feature. Movement of the drive member between the second and third positions moves the arm between the closed and open positions.
Abstract:
A mechanism is provided for balancing and positioning a sash of a self-balancing double-hung window assembly. The mechanism may include a fixed length cable, a pulley, first and second brackets and an adjustment member. The fixed length cable may include first and second ends. The pulley may support the cable. The first bracket may include one or more attachment points relative to the first end of the cable and may include an upper end and a lower end. The second bracket may be movable relative to the first bracket and may be configured to support the sash. The adjustment member may engage and extend through the lower end of the first bracket and may be movable relative to the first bracket to cause corresponding movement of the second bracket relative to the first end of the cable.
Abstract:
A hardware assembly providing a motion-activated vent stop for a vent window assembly. The hardware assembly can detect excessive forces acting on the vent and quickly arrest any unintended or induced movement of the vent while enabling the regular function of the vent window under normal operating conditions. When an opening force acting on the vent exceeds a predetermined value, the resulting torque causes a shoe to pivot and engage a stepped profile of a guide slot of a track along which the shoe moves. Once engaged, the shoe cannot move along the track and continued movement of the vent is halted. The shoe includes a biasing member that engages the guide slot and produces a counter-torque that tends to bias the shoe generally vertically in the guide slot and enable the shoe to travel freely under normal operating conditions.
Abstract:
A multi-bar linkage assembly for a pivotally mounted window sash and, more particularly, a high-capacity hinge assembly is disclosed. The hinge assembly is less susceptible to deflection during operation and may be used with and support window vents more than 100 in. tall and weighing more than 400 lbs. Notwithstanding the hinge assembly's wide range of use, the hinge assembly stack height does not exceed the industry standard of 0.625 in. for conventional hinge assemblies incapable of use in heavy-duty applications. The hinge assembly may be used with standard form window frames without requiring redesigning or otherwise modifying the window frame's standard form cross-section.

The drive member is received in a channel defined by the stationary member for linear motion therein relative to the stationary member and the arm among a first position in which the drive member engages a locking feature of the window vent, a second position in which the drive member is spaced apart from and disengaged from the locking feature without rotating the arm out of the closed position, and a third position in which the drive member is further spaced apart from the locking feature. Movement of the drive member between the second and third positions moves the arm between the closed and open positions.
Abstract:
A hinge assembly is disclosed that may include one or more leaves that can be connected to a panel. The hinge assembly may further include a barrel having a passage through which a pivot pin passes. A spacer is positioned in an opening between a first barrel section and a second barrel section. Bushings are disposed within the first and second barrel sections.
Abstract:
A hinge assembly for moving a window sash relative to a window frame may include a track (18), a slider (20), first, second and third links (22,24,26), and a stop member (30). The slider (20) may engage the track (18) and may be translatable along the track (18). The first link (22) may be pivotably coupled to the track (18). The second link (24) may be pivotably coupled to the slider (20). The third link (26) may be pivotably coupled to the first and second links (22,24). The stop member (30) may engage the track (18) and may be configured to limit translational motion of the slider (20). The stop member (30) may be movable between a plurality of positions. Each of the plurality of positions may correspond to one of a plurality of ranges of translational motion of the slider (20).
Abstract:
A sliding closure assembly includes a frame assembly, at least one sliding closure panel, a second panel, and a powered actuator. The frame assembly has a first track portion, a second track portion, and a catch portion. The sliding closure panel slides within the first track portion of the frame assembly. The second closure panel is adjacent to the at least one sliding closure panel and is positioned within the second track portion of the frame assembly. The powered actuator assembly is positioned adjacent to the second panel and entirely within the second track portion. The sliding closure panel slides within the first track portion of the frame such that an opening is formed through the sliding closure assembly when the sliding closure panel is in the opened position and the opening is closed when the sliding closure panel is in the closed position.
