A draft guard for a window assembly includes a piece of weatherstopping material and a bend in the piece of weatherstopping material with the bend defining a horizontal component and a vertical component angularly offset from the horizontal component, a foam seal forming a closed member around the horizontal component and extending outwardly from the horizontal component, and at least one fin extending outwardly from and integral with at least one side of the vertical component.

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.

A hinge includes a first end plate, a second end plate and at least one inner plate positioned between the first end plate and the second end plate. The first end plate is connected to the at least one inner plate by a first pin that extends through the first end plate and the at least one inner plate. The second end plate is connected to the at least one inner plate by a second pin that extends through the first end plate and the at least one inner plate. The first end plate is rotatable relative to the at least one inner plate about a first pivot axis defined by the first pin. The second end plate is rotatable relative to the at least one inner plate about a second pivot axis defined by the second pivot pin.

A carrier for a window sash has a balance connecting portion configured to be connected to a window balance. A vertical rail system is configured to slidingly engage a bracket of the window sash.

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 frame comprising a plurality of elongate frame members defining a frame opening for receiving a window for closing the frame opening. At least one of the elongate frame members having a longitudinally extending recess; and a slide mechanism received within the recess, wherein the slide mechanism comprises a first track fixed within the recess and a second track movable within and along the recess and coupled to the first track via a rotary coupling member such that movement of second track along the recess causes the rotary coupling member to rotate, wherein the second track is arranged to be coupled to the window when the window is received within the frame opening to enable the window to slide relative to the frame.

A carrier for a window sash has a balance connecting portion configured to be connected to a window balance. A vertical rail system is configured to slidingly engage a bracket of the window sash.

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 present disclosure is directed to overhead doors and overhead door operation. More specifically, the present disclosure relates to a direct drive counter balancing system for operating overhead doors. In some examples, the direct drive counter balancing system of the present disclosure is for overhead door systems used in segmented door arrangements for box trucks.

A door suspension device includes a driving-side member, a hanger, an elastic member, and a first adjustment bolt. The hanger is configured so as to be displaceable in an opening and closing direction in conjunction with the driving-side member and supports a door. The elastic member allows relative displacements of the driving-side member and the hanger by elastically deforming in accordance with a load between the driving-side member and the hanger. The first adjustment bolt is a member for adjusting an initial value of a load that acts between the driving-side member and the hanger. The first adjustment bolt includes a male screw section to be fixed to the driving-side member, and a head which is arranged so that an axial force acting on the first adjustment bolt is received by an edge of the hanger.
