Abstract
A window balance assembly and a mounting bracket for a window balance assembly are provided. The mounting bracket includes a planar-shaped body having opposed planar surface with an opening extending through the body from one surface to the other. The mounting bracket further includes first and second coupling members extending from the same side of the body that selectively engage a curl spring and a carrier of a window balance assembly. The first coupling member is oriented in a different direction than the second coupling member such that the first coupling member has an upward orientation and the second coupling member has a downward orientation.
Claims13
A window balance configured to be disposed in a jamb of a hung window assembly and configured to connect to a moveable sash of the hung window assembly, the window balance comprising:
- a carrier comprising an upper end, a lower end and a housing, the housing comprising a first housing portion and a second housing portion which together define an interior space, and a receiver disposed near the lower end of the carrier and configured to receive a pivot bar of the moveable sash of the hung window assembly;
- and
- a constant force curl spring comprising a curled portion within the interior space of the housing of the carrier and an uncurled end portion extending from the curled portion outside of the interior space of the housing of the carrier;
- and
- a mounting bracket comprising a body having a first surface, a second surface, a top, a bottom, a front, a rear, and an opening through the body configured to receive a fastener for attaching the mounting bracket to a wall of the jamb;
- a first coupling member extending from the front of the body at a non-perpendicular angle and comprising an upwardly projecting first distal end, the first distal end configured to selectively engage the uncurled end portion of the curl spring;
- a second coupling member extending from the front of the body at a generally perpendicular angle and comprising a downwardly projecting second distal end, the second distal end configured to selectively engage the uncurled end portion of the curl spring;
- and
- wherein in an uninstalled, assembled configuration of the window balance, the mounting bracket is retained with the carrier.
A window balance assembly configured for installation in a jamb channel of a window frame comprising:
- a carrier;
- a curl spring at least partially disposed in the carrier and having an uncurled end portion extending from the carrier;
- a mounting bracket comprising:
- a C-shaped body having a back wall having a front surface, a rear surface and at least one engagement opening;
- a first side wall disposed adjacent to the back wall and extending perpendicularly to the back wall;
- a second side wall disposed adjacent to the back wall and extending perpendicularly to the back wall, the first side wall and the second side wall opposing one another;
- wherein each of the first side wall and the second side wall has an inside face, an outside face, a front face, a top face, and a bottom face, the top face being disposed opposite to the bottom face, and the inside face being disposed opposite the outside face;
- wherein the inside face of the first side wall opposes the inside face of the second side wall;
- wherein the rear surface of the back wall is disposed opposite the front surface of the back wall, and the rear surface of the back wall is disposed opposite the front faces of the first side wall and the second side wall;
- wherein each of the first side wall and the second side wall has a recessed portion, a cover portion, and a slot;
- wherein the recessed portion extends from an opening on the outside face toward the inside face and terminates at an inner recess surface, and the recessed portion also opens to the front face;
- wherein the slot extends from the front face toward the rear surface and includes an opening on the front face and an opening on the bottom face, the slot being interconnected with the recessed portion;
- wherein the cover portion is a planar-shaped member that extends from the rear surface and covers the slot;
- wherein a boss extends from the inner recess surface of the recessed portion toward the outside face, the boss being configured to selectively engage the uncurled end portion of the curl spring;
- and
- wherein the slot is configured to cover a portion of the uncurled end portion of the curl spring when the boss is engaged with the uncurled end portion of the curl spring;
- wherein the jamb channel comprises a jamb wall and the back wall of the mounting bracket is disposed adjacent to the jamb wall;
- wherein at least one spring finger is disposed on the jamb wall, the at least one spring finger configured to selectively engage the at least one engagement opening in the back wall of the mounting bracket.
