Abstract
A window assembly is disclosed that includes a double-hung window aesthetic with an alternative opening procedure and mechanism. The window assembly may include various hardware systems. The hardware systems may include locking portions to assist in locking sash members to a frame and balance assembly for moving the sash members. The window assembly may be formed of selected materials.
Claims26
A hardware system for use with a fold-up window assembly having an upper sash, a lower sash, and a frame, the hardware system comprising:
- a balance assembly having a spring member received within a case and couplable to the lower sash;
- a first hinge assembly configured to hingedly interconnect the upper sash and the lower sash, the first hinge assembly having a first leaf configured to connect to the lower sash, a second leaf configured to connect to the upper sash, and a first hinge pin;
- and
- a second hinge assembly configured to hingedly interconnect the upper sash and a header of the frame, the second hinge assembly having a third leaf configured to connect to the upper sash, a fourth leaf configured to connect to the header of the frame, and a second hinge pin;
- wherein at least the first hinge assembly and the second hinge assembly are configured to cooperate with the upper sash and the lower sash to allow the upper sash and the lower sash to fold relative to the frame such that the upper sash rotates around the second hinge pin of the second hinge assembly near the header of the frame and the lower sash rotates around the first hinge pin as the upper sash and lower sash fold.

A hardware system for use with a fold-up window assembly having an upper sash, a lower sash, and a frame, the hardware system comprising:
- a slide locking assembly configured to selectively couple the lower sash to the frame of the window assembly, the slide locking assembly including:
- a track member configured to be fixed and recessed in a groove formed in an upper rail of the lower sash;
- and
- a locking bar received within and movable relative to the track member;
- a first hinge assembly configured to interconnect the lower sash and the upper sash;
- and
- a second hinge assembly configured to interconnect the upper sash and a header of the frame;
- wherein, when the hardware system is installed on the fold-up window assembly, at least the first hinge assembly and the second hinge assembly cooperate with the upper sash and the lower sash to allow the upper sash and the lower sash to fold relative to the frame such that the upper sash rotates around a second hinge pin of the second hinge assembly near the header of the frame and the lower sash rotates around a first hinge pin as the upper sash and lower sash fold between a closed position and an open position and placement of the track member within the groove allows the lower sash to lie flush against the upper sash to allow the upper sash and the lower sash to assist in providing an appropriate seal in the closed position.
5 more elements
A hardware system for use with a fold-up window assembly having an upper sash a lower sash, and a frame, the hardware system comprising:
- a balance assembly including:
- a case configured to be fixed to the frame above the lower sash when the window assembly is in a closed configuration;
- a spring member received within the case, the spring member configured to be coupled to the lower sash to apply a force to the lower sash;
- a sash carrier having at least one housing member;
- a friction enhancement member carried by the sash carrier and configured to engage a iamb channel of the frame to resist a spring force of the spring member;
- and
- a pin configured to extend from the lower sash and interconnect the spring member and the lower sash;
- a first hinge assembly configured to interconnect the lower sash and the upper sash;
- and
- a second hinge assembly configured to interconnect the upper sash and a header of the frame;
- wherein, when the hardware system is installed on the fold-up window assembly, at least the first hinge assembly and the second hinge assembly are configured to cooperate with the upper sash and the lower sash to allow the upper sash and the lower sash to fold relative to the frame;
- and
- wherein the spring member assists in moving the lower sash at least to move the window assembly to an open configuration.

A fold-up window assembly comprising:
- a frame;
- an upper sash;
- a lower sash;
- and
- a hardware system configured to allow the upper sash and the lower sash to fold up to an open configuration and to unfold to a closed configuration, the hardware system including:
- a balance assembly including:
- a case fixed to the frame above the lower sash when the window assembly is in the closed configuration,
- a spring member at least partially received within the case and coupled to the lower sash to apply a force to the lower sash;
- a sash carrier having at least one housing member;
- a friction enhancement member carried by the sash carrier and configured to engage a iamb channel of the frame to resist a spring force of the spring member;
- and
- a pin configured to extend from the lower sash and interconnect the spring member and the lower sash;
- wherein the spring member assists in moving the lower sash at least to move the window assembly to the open configuration.
