Window counterbalance brake shoe and spring assembly with improved brake strength
A counterbalance system that is set into the guide track of a tilt-in window. The counterbalance system utilizes a brake shoe that is attached to a ribbon spring. The ribbon spring has a shaped head that is retained by the brake shoe. A flexible tab is formed in the ribbon spring near the shaped head. A protrusion extends from the brake shoe. The brake shoe has a receptacle that receives and retains the shaped head of the ribbon spring, therein interconnecting the ribbon spring to the brake shoe. A cam is supported within the brake shoe. The brake shoe expands when the cam is turned. This causes the protrusion on the brake shoe to be biased against the flexible tab in the ribbon spring. This, in turn, causes the flexible tab to flex and extend away from the ribbon spring at an inclined angle. Within the guide track of the tilt-in window, the extended flexible tab acts as a barb and engages the side wall of the guide track. This helps prevent the window sash from being moved when the window sash is tilted open.
