Ribbon coil spring anchor mount system for use in a window counterbalance assembly
A counterbalance system for a window sash in a window frame. The window frame has guide tracks. The guide tracks have wall surfaces. The wall surfaces are supported by reinforcement ribs. A mounting slot is formed in the guide track. The mounting slot is formed in a limited area of a wall that is not supported by a reinforcement rib. A coil spring is provided. The coil spring is made of a steel ribbon having a first end, an opposite second end, and a slot engagement configuration proximate said second end. The coil spring has a wide first width from its first end to the slot engagement configuration. This first width is too large to directly engage the mounting slot. The steel ribbon is reduced to a second width through the slot engagement configuration and continuing to the second end to pass into the mounting slot.
