WINDOW TREATMENT HAVING A SPRING WRAP BRAKE
Described herein are brake assemblies that may be useful for window treatments, such as spring-balanced motorized window treatments, including spring-balanced shades. The brake assemblies include brake springs of wire formed into a plurality of coils. The plurality of coils may terminate in a tang assembly, the tang assembly having a tang and a support portion. A support portion supports the tang when the tang is acted on by a force (e.g., a spring tightening or a spring loosening force). The support portion greatly reduces the hazard of the tang bending, because the tang is supported at each of its ends. With less chance of bending at the tang, a smaller wire diameter may be used for the brake spring, which creates less drag when rotating in a driven state. In the case of battery-driven shades, less drag saves battery life.
