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.

Abstract: A window vent assist mechanism for use with a vent window operable in a closed position and in a vented position can include a first support configured to connect to a header of a window frame and a second support configured to connect to an upper rail of a window vent disposed in the window frame. The window vent assist mechanism also includes a biasing member disposed between the header of the window frame and the upper rail of the window vent and nearer to an inner side of the vent window and a center of gravity of the window vent. The biasing member is configured to exert a force to urge the window vent to move relative to the window frame to reduce an operating force required to move the window vent to the vented position.
