Abstract
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.
Claims27
A window balance assembly for installation in a window assembly, the window balance assembly comprising:
- a carrier;
- a spring element having first and second portions, the first portion being coupled to the carrier;
- and
- a mounting bracket engaging the second portion of the spring element and selectively engaging the carrier, the mounting bracket engaging the carrier in an uninstalled configuration and including a first mounting surface disposed at a non-perpendicular angle relative to an exterior surface of the carrier when the window balance assembly is in the uninstalled configuration, the first mounting surface being 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 assembly comprising:
- a carrier comprising a body including a projection located at a first end of the body, and a cam member rotatably supported at a second end of the body;
- a mounting bracket releasably coupled to the carrier at the projection;
- and
- a spring element including a first portion and a second portion, the first portion being disposed in the body and the second portion extending from the body and engaging the mounting bracket;
- wherein either or both of the mounting bracket and the projection deform in response to application of a force to uncouple the mounting bracket from the carrier.
A window balance assembly comprising:
- a carrier rotatably supporting a cam member and having a spring element at least partially disposed therein;
- and
- a mounting bracket engaging the spring element and being releasably coupled to the carrier;
- wherein either or both of a portion of the mounting bracket and a portion of the carrier deform in response to application of a force to uncouple the mounting bracket from the carrier.
