ABSTRACT:
An improved, spring-biased take-up clamp assembly for elongated tie-down elements such as cables, ropes or mobile home tie-down straps is provided which permits simplified, infinitely adjustable take-up and tightening of the tie-down element with secure locking at any desired position and without the use of conventional turnbuckles or other devices using interference-fit structure for spindle-retaining purposes. In preferred forms the assembly includes a rotatable take-up mandrel or spindle for a tie-down element, an apertured mounting plate fixed to the upper end of an embedded earth anchor, and a motion-checking snubber spring operatively coupled between the strap spindle and mounting plate for holding the strap against loosening under tension loads while at the same time permitting relatively easy, one-man tightening thereof as desired. The snubber spring includes a pair of spaced torsion spring portions in gripping engagement with the wind-up spindle, and a bail portion engageable with the anchor mounting plate for preventing inadvertent slippage of the hold-down element.
