Anchoring arrangement for heavy coil springs, primarily in coil spring carried playground devices

摘要

Adjacent the rigidly anchored end of a vertical coil spring, which carries out transverse oscillations, the spring is subjected to considerable breaking forces which limit the lifetime of the spring. At least one abutment is provided to cooperate with a spring portion slightly spaced from the rigidly anchored spring end such that this spring portion is permitted to carry out only a limited vertical movement, whereby the breaking influence on the spring is largely reduced.
