Abstract
The plug is for use with a torsion spring and is removably connectable to a component of a counterbalancing mechanism. The plug comprises a generally circular base and a hollow body coaxially projecting from the base. The body has an outer surface for receiving an end of the torsion spring. At least two spaced-apart connection flanges are axially projecting from the base and opposite to the body. Each flange comprises a pair of opposite side shoulders. The flanges are removably inserted into the component for connecting the plug thereto in interfering engagement. Plugs that are constructed accordingly create modular and versatile sub-assemblies with other components. Such plugs are then easily secured in place and do require an extensive inventory of parts to accommodate all situations.
