摘要： Disclosed is a discretionarily adjustable friction force block and tackle balance system comprising a housing and an adjustable break, wherein means are provided for adjusting the friction force between an inner surface of the housing and the adjustable break. An adjustable balance system comprising a housing, a floating anchor assembly, a fixed anchor assembly, a cord, and an elastic suspension is also disclosed. In an embodiment, the housing is a 3-side or 4-side tube or channel. There is at least one elongated hole or slit on at least one surface of said housing. An adjustable break is mounted inside the floating anchor subassembly. Moving the window sash also causes the floating anchor subassembly to move. When the floating anchor subassembly is moved to a position just under elongated hole on the said housing, the adjust screw installed in the adjustable break is exposed. The desired friction force can be easily created and adjusted by turning the adjust screw in the appropriate direction to splay or retract the adjustable break for balancing window sashes having widely varying sizes and weights.
