Spring-stretch-reducing window sash balance

A sash coupling is adapted to be connected to one side of a sash which slides vertically in parallel channel sash guides mounted within a sliding sash window frame. Secured to the top of the sash coupling is the lower end of a flexible sash cable, the outer end of which extends upward to and around a stationary outer pulley pivotally mounted on a transverse pulley support at the top of the sash guide, whence an intermediate section of the cable extends downward to and around a vertically-movable traveling pulley mounted on a balancing-spring coupling to which the upper end of the elongated sash-balancing tension spring is hooked, whence an inner section of the cable extends upward to an anchorage on the upper end of the sash guide. The lower end of the elongated sash-balancing spring is hooked over the lower end of the sash guide. For a double-hung sliding sash installation, the upper sash is balanced in a similar manner. For By arranging in this manner the sash cable in three sections around two pulleys, the stretch of the sash balancing spring is reduced to but a fraction of the distance through which the sash is moved during the opening operation thereof. This is in contrast to the much greater stretch with a consequently greater varation in the balancing force applied to the sash by a single elongated sash balancing spring stretched directly between the sash and the top of the channel sash guide.

Pre-tension anchorage for spiral balance

The spiral balance includes a containment tube, a spiral rod and a torsion spring that traverses the length of the containment tube. The device includes a pre-tensioning insert that is contained within an anchorage fixed within the upper end of the containment tube. At least one boss formed at the base of a bore within the pre-tensioning insert defines a channel that receives the upper end of the spiral rod. To apply a pre-tensioned force to the spiral balance, the lower end of the spiral rod is pulled from the lower end of the containment tube, turned a number of revolutions and reinserted into the containment tube without being allowed to rotate. The upper end of the spiral rod is non-rotatably retained within the channel by the boss to prevent it from losing its pre-tensioned force.

Parallel axes compound balance

An apparatus and method to substantially cancel out the opposing torsional forces of the torsion spring of a spiral rod subassembly and the extension spring of a compound spiral rod balance on the carrier element. The extension spring and the rod spiral balance subassembly are parallel, connected at their lower ends to a carrier element and at their top ends either to an upper mounting cap or separately to the wall of the jamb channel. The spiral rod is turned a pre-determined number of times in a direction opposite from that in which the extension spring is turned so that the torsional forces acting on the carrier element from the torsion spring and the extension spring substantially cancel out each other. The balancing out of the counteracting torsional forces eliminates or substantially reduces the friction between the carrier element and the jamb channel.

Window regulator mechanism having counterbalancing member

The present invention is a window regulator mechanism for moving a window panel mounted within a motor vehicle door. The mechanism comprises an elongated guide rail (18) member mounted within the vehicle door. A window moving structure (94) engages the window panel and is slidably mounted on the guide rail member (18) to allow the window panel to be moved generally vertically with respect to the vehicle door. A manually operated actuating mechanism slidably moves the window moving structure (94) along the guide rail member (18). An elongated, flexible counterbalancing member (90) is constructed and arranged to apply a counterbalancing force to the window panel that opposes a force of gravity acting on the window panel. The counterbalancing member has a first end (96) fixedly attached within the motor vehicle door, a second end (92) fixedly attached to the window moving structure (94), and an intermediate portion extending over a guiding portion (102) disposed above an uppermost position of the window moving structure. The counterbalancing member is formed from a flexible elastomeric material and is elastically deformed to an initial elastically deformed state when the window moving structure is in its uppermost position. The counterbalancing member is configured to elastically deform beyond its initial elastically deformed state as the window panel moves downwardly with respect to the vehicle door against the counterbalancing force of the counterbalancing member to thereby oppose the force of gravity acting on the window panel and thereby provide a controlled, downward movement of the window panel. The counterbalancing member resiliently returns to its initial elastically deformed state as the window panel moves upwardly with respect to the vehicle door. The counterbalancing member applies the counterbalancing force to oppose the force of gravity acting on the window panel as the window panel moves upwardly to thereby facilitate upward movement of the window panel.
