Abstract
A self-adjusting, tie-down device that maintains consistent tension on loads in spite of shifting, settling or environmental change, i.e., hot/cold, dry/wet. The device includes a cam buckle assembly having a proximate end and a distal end. An inelastic strap is adjustably affixed to the distal end of the cam buckle. An elastic strap is pivotally attached at the proximate end of the cam buckle. Steel hooks are disposed at the respective free ends of the elastic and inelastic straps.
Claims11
A self-adjusting tie-down device having a working length, the device comprising:
- a tightening mechanism, said tightening mechanism having a length;
- a non-elastic strap, said non-elastic strap being adjustably secured to said tightening mechanism, said non-elastic strap having an adjusted length;
- an elastic strap having a length, a distal end and a proximate end, the proximate end of said elastic strap being secured to said tightening mechanism, the device having a working length equal to the combined total length of the elastic strap, the tightening mechanism, and the adjusted non-elastic strap, the length of said elastic strap being less than one-half the working length of the device.
A self-adjusting tie-down device, comprising:
- a tightening mechanism, said tightening mechanism having a length;
- a non-elastic strap, said non-elastic strap being adjustably secured to said tightening mechanism, said non-elastic strap having an adjusted length;
- an elastic strap having a length, a distal end and a proximate end, the proximate end of said elastic strap being secured to said tightening mechanism, wherein the length of said elastic strap is less than one half the combined total length of said tightening mechanism and said non-elastic strap.
A self-adjusting tie-down device, comprising:
- a tightening mechanism, said tightening mechanism having a length, a first end and a second end;
- a non-elastic strap, said non-elastic strap being adjustably secured to said tightening mechanism at the second end of said tightening mechanism, said non-elastic strap having an adjusted length;
- an elastic strap having a length, a distal end and a proximate end, the proximate end of said elastic strap being pivotally secured to the first end of said tightening mechanism, the length of said elastic strap being less than one half the combined total length of said tightening mechanism, the adjusted length of said non-elastic strap and the length of said elastic strap.
