Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
An anchor, for securing the lower end of a coil spring to a frame member embodying spaced, parallel supports, said supports having vertically-spaced, horizontal, upwardly and downwardly-facing sides, said anchor comprising a base plate corresponding in transverse width to the support and in length to an incremental portion thereof for sliding engagement with the upwardly-facing side of the support, a pair of longitudinally-spaced lugs on the upwardly-facing side of the base plate and means for slidably securing the base plate to the support comprising transversely-spaced flanges at the opposite edges of the base plate depending from the downwardly-facing side thereof for engagement with the sides of the support, said flanges being yieldably resistant to displacement and latch elements at the lower edges of the flanges engaged with the downwardly-facing side of the support.
Claim 2
Dependent Claim
