| 20120030903 | Side Load Carrier and Balance System for Window Sashes - A carrier assembly can be used to couple a balance assembly with a window sash. The carrier assembly can engage the window sash to transfer a force from the balance assembly to balance a weight of the window sash. The carrier assembly, due to interactions of the window sash with the carrier assembly and the balance assembly with the carrier assembly, can tightly engage the window sash, either directly or through a bracket, to substantially eliminate unselected movement or forces applied from the balance assembly. | 02-09-2012 |
