A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier. The mounting bracket may include a first mounting surface disposed at a non-perpendicular angle relative to an exterior surface of carrier when the window balance assembly is in an uninstalled configuration. The first mounting surface may be substantially parallel to the exterior surface of the carrier when the window balance assembly is in an installed configuration and the mounting bracket is disengaged from the carrier.

A window balance may include a shoe body with an elongate portion and an enlarged portion. The elongate portion may include at least one carrier section for supporting a coil spring and an enlarged portion may include a locking element and a cam in communication with the locking element. The width of the enlarged portion may be greater than the width of the elongate portion. The spring may rest in the carrier section and may be secured to a window jamb with a fastener or a mounting element.

A constant force window balance assembly for a side-load, hung window is disclosed. A side rail of a window sash disposed in a jamb channel has a first opening. The balance assembly is installed in the jamb channel and engages the sash at the first opening to support the sash with a counterbalance force. A carrier of the balance assembly includes a body having a sash engaging seat located at an upper end that directly engages the first opening in the side wall of the side rail of the window sash. The carrier can also include a lip located at an inner side of the carrier and extending upwardly from the sash engaging seat. The carrier can also include a projection at an upper end of the body to engage a retaining aperture in an uncurled end portion of a curl spring in a pre-installed configuration of the window balance.

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.

A power transfer assembly includes a window balance assembly, a pivot bar, and an electrically conductive pathway. The window balance assembly includes a first portion configured to be fixed in place and a second portion configured to be movable relative to the first portion. The pivot bar is conductively coupled to the second portion of the window balance assembly. And, the electrically conductive pathway extends between the window balance assembly and the pivot bar.

An assembly for mounting a door with a vehicle compartment includes an arm coupled with the compartment and with the door, a track fixed with the compartment, and a carrier pivotably coupled with the door and slidable along the track. The assembly further includes a spring coupled between the door and the compartment such that a contraction of the spring alone causes the door to move with rotation of the arm and movement of the carrier along the track. A track cover engages the carrier to prevent disengagement of the carrier from the track.

Embodiments of the invention provide a opening and closing assembly for a rigid door panel that is rotatably attached to a roller received within a track on a door frame member. A support member can be rotatably attached to the door panel. A first pivot arm can extend inboard from the support member to pivotally attach to an inboard frame member. Upon application of an upward force to the door panel, the first pivot arm can pivot with respect to the first inner frame member to move the support member in an arcuate path. The support member can thereby move the door panel upward and inboard along a door path at least partly defined by the track, with a lower end of the door panel not extending substantially outboard of the door frame member as the door panel moves along the door path.

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element is coupled to the carrier and, in an uninstalled, assembled configuration of the window balance assembly, the mounting bracket is retained with the carrier.

A window balance assembly includes: a housing with first and second interior spaces; a receiver rotatably supported in the first interior space; a curl spring disposed in the second interior space with a tail extending out of the housing; and a mounting bracket. The tail includes: a neck and a head. The mounting bracket includes first and second flanges. First and second guide members protrude from opposite sides of a rear surface of the first flange, and slidably support the tail proximate to the rear surface. First and second ramp members on the rear surface include an upper recess, and are spaced permitting passage of the neck therebetween. When the tail slides between the second guide members the ramp members force the head away from the rear surface, until the head passes beyond the ramp members. The curl spring biases the head into the recesses.

A window balance assembly includes: a mounting bracket, housing, receiver, and curl spring. A first housing portion has a first and second cantilevered protrusions at its first and second ends. A second housing portion has first and second cantilevered protrusion protruding from first and second interior portions of its front wall. Receiver rotation from first to second positions results in the first cam causing the first cantilevered protrusion of the second housing portion to deform outwardly in a first direction causing the first cantilevered protrusion of the first housing portion to similarly deform outwardly, and the second cam causes the second cantilevered protrusion of the second housing portion to deform outwardly in a second direction causing the second cantilevered protrusion of the first housing portion to similarly deform outwardly. Each cantilevered protrusion has undulations configured to grip the interior walls of a master window frame.
