Abrégé

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.

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.

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.

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.

A curl spring sash shoe cassette improves upon the suggestions of U.S. Pat. Nos. 5,353,548 and 5,463,793 by providing a mounting bracket that holds an uncurled length of the curl spring and is securely mounted on top of the shoe cassette to maintain an assembly of the shoe body, the curl spring, and the mount during shipment to a window manufacturer. The mount can receive two mounting screws to resist torque caused by curl springs and sash weight. The shoe is also improved to facilitate removal and reinsertion of sash pins into the tilt lock cams of the shoes and ensure that shoe body halves do not rotate relative to each other when sash tilting splays the body halves apart to lock them in a shoe channel.

A 4-bar linkage assembly for mounting a sash to a frame member of a window assembly. The linkage assembly including a vent bar having an offset portion and a base portion that fits within a sash channel of the sash. The vent bar includes a fixed connection extending between the offset portion and the base portion for supporting the offset portion and projecting between overhanging rails of the sash channel. The offset portion forms a stop which engages an end of the sash channel for locating the vent bar within the sash channel.
