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 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.

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.

The displacement device (10), which is provided for the installation in a door compartment (18) of a functional entity (1), comprises a drive device (2) preferably comprising a housing (210), a spring mechanism (211), a pull cord pulley (212) coupled to the spring mechanism (211), and a pull cord (22), which is wound onto the pull cord pulley (212) and is guided preferably via at least one deflection pulley (231, 232, 233) up to a holding element (33, 339; 72), a mounting profile (14), which is connected or connectable by mounting hinges (131) to a single-part or multi-part door (11), which is held vertically aligned and displaceable by a holding device (4); which is connected on an upper end piece to an upper guide carriage (5) that is supported displaceably on an upper guide rail (15) and/or which is connected on a lower end piece to a lower guide carriage (6) that is supported displaceably on a lower guide rail (16); and which, connected to the drive device (2), is automatically displaceable between a rear-sided end position (S2) at the rear-side of the displacement device (10) and a front-sided end position (S1) at the front-side of the displacement device (10); and

an adjustment device (3, X3), with which a pre-tension on the spring mechanism (211) of the drive device (2) can be set. According to the invention the adjustment device (3, 3X) is arranged separated from the drive device (2) and comprises an adjustment element (33, X33) which is rotatable and lockable or displaceable and lockable and which adjustment element (33, X33) cooperates with the pull cord (22) led out of the drive device (2) in such a way that the pull cord (22) is pullable out of the drive device (2) by rotation or displacement of the adjustment element (33, X33) to set a corresponding pre-tension of the spring mechanism (211).

The present invention provides a closing mechanism for closing a door/window. The door/window slides relative to a door/window frame which incorporates a door/window jamb. The closing mechanism comprises a biasing assembly extending between the door and the door jamb, wherein the biasing assembly provides a biasing force to bias the door towards a closed position. The closing mechanism comprises a speed control assembly operatively connected to the biasing assembly, to selectively control the speed at which the door closes. The closing mechanism also comprises a restraining assembly operatively connected to the speed control assembly to control the acceleration of the door as the door approaches the closed position.
