Abstract
The present invention relates to a novel torsion spring apparatus and method wherein anchor loops are formed in the end coil of the torsion spring to permit anchoring the spring directly to the appropriate mounting bracket. The provision of anchor loops in the end coil of the torsion spring effectively eliminates the requirement for conventional mounting inserts for the torsion spring and simultaneously increases the effective length of the torsion spring or, alternatively, permits the torsion spring to be shortened by the number of coils that would be otherwise rendered ineffective by the presence of a prior art insert.
