Abstract

An improved tie-down is provided have a self-locking lock arrangement formed in a loop of the tie-down rope so as to effect releasable locking of the rope at a readily adjustable length. The locking arrangement is formed by the rope itself rather than separate mechanisms and provides an improved arrangement for securing cargo.

Claims

1. A tie-down arrangement comprising:

a length of flexible rope;

first and second connector sections associated with said rope and each configured for connection to corresponding attachment locations, said tie-down arrangement having a length defined between said first and second connector sections which said length is adjustable for tensioning said tie-down arrangement and thereby securing articles;

a guide arrangement proximate said first connector section having a guide opening which slidably receives said rope; and

said rope having a fixed rope end associated with said first connector section, a second rope end, and one or more loops formed between said first and second rope ends wherein each said loop has a first leg extending toward said second connector section, a first turn proximate said second connector section, a second leg extending back toward said first connector section and a second turn slidably received through said guide opening wherein said rope extends from said guide opening to define a locking leg which terminates at said second end, said locking leg entering into and extending interiorly through a locking section of said rope and then exiting from said locking section, said locking leg being slidable through said locking section to adjust the length of said tie-down arrangement wherein tensioning of said rope causes said locking section to constrictively grip the portion of said locking leg disposed interiorly therein to prevent slippage of said rope through said locking section.

2. The arrangement according to claim 1, wherein said rope is a plaited rope.

3. The arrangement according to claim 2, wherein said rope is comprised of multiple strands which define multiple plaits and an interior of said rope through which said rope is insertable.

4. The arrangement according to claim 3, wherein said strands constrictively grip said rope disposed interiorly therein.

5. The arrangement according to claim 1, wherein said guide opening is defined by an opening formed through said rope.

6. The arrangement according to claim 5, wherein said guide opening in said rope includes a rigid device secured within said rope.

7. The arrangement according to claim 1, wherein said guide opening is defined by a rigid ring, and each said second turn of each said loop extends slidably there through.

8. The arrangement according to claim 1, wherein said locking leg extends successively from said second turn of said loop wherein said arrangement is tightened by pulling of said second rope and sliding of said locking leg through said locking section which generates rope tension and prevents return sliding of said locking leg through said locking section, said arrangement being released by pulling of said second leg of said loop in a longitudinal direction away from said locking section.

9. A tie-down assembly comprising;

a length of flexible rope;

first and second connector sections associated with said rope which define opposite ends of said assembly and are configured for connection to corresponding attachment locations, wherein said tie-down arrangement has a length defined between said first and second connector sections which is adjustable for tensioning said tie-down arrangement;

a guide arrangement which is disposed proximate said first connector section and has a guide opening through which said rope is slidably received;

said rope having a fixed rope end associated with said first connector section, a free rope end extending freely, and at least one loop formed between said fixed rope end and said free rope end, each said loop having a first leg extending between said first and second connector sections, a first turn slidably engaged with said second connector section, a second leg extending back toward said first connector section and a second turn slidably received through said guide opening wherein pulling of said free rope end pulls said rope through the guide opening to shorten the size of the loop and thereby shorten the distance between the first and second connector sections; and

said free end of said rope extending from said guide opening to define a locking leg wherein said locking leg is inserted into and extends interiorly through a locking section of said rope and then exits from said locking section to terminate at said free end, said locking leg being slidable through said locking section to adjust the length of said tie-down arrangement wherein pulling of said free rope end in a tightening direction tensions said rope to cause said locking section to constrictively grip the portion of said locking leg disposed interiorly therein and prevent slippage of said rope through said locking section in a release direction opposite said tightening direction, said constrictive locking of said rope by said locking section being releasable by longitudinal pulling of said second loop leg in said release direction.

10. The assembly according to claim 9, wherein said rope is comprised of multiple strands which surround said locking leg and constrictively grip said rope when under tension.

11. The assembly according to claim 10, wherein said rope is a plaited rope.

12. The assembly according to claim 9, wherein said first turn slidably extends through an eyelet associated with said second connector section.

13. The assembly according to claim 12, wherein said second connector section includes a hook.

14. The assembly according to claim 9, wherein said locking section is defined in said first leg of said loop and constrictively grips said rope disposed interiorly therein.

15. The assembly according to claim 14, wherein said guide opening is disposed between said locking section and said first connector section.

16. The assembly according to claim 15, wherein said guide opening is defined by a rigid eyelet through which said second turn is slidably received.

17. The assembly according to claim 9, wherein said rope defines a plurality of said loops.

18. A tie-down assembly comprising:

a length of flexible rope;

first and second connector sections associated with said rope which define opposite ends of said assembly and are each configured for connection to corresponding attachment locations, said tie-down arrangement having a length defined between said first and second connector sections which said length is adjustable for tensioning said tie-down arrangement;

said rope having a fixed rope end associated with said first connector section, a free rope end extending freely, and at least one loop formed between said fixed rope end and said free rope end, at least one said loop having a first leg extending toward said second connector section, a first turn slidably engaged with said second connector section, a second leg extending back toward said first connector section and a second turn, said first leg of said loop defining a locking section disposed between said first and second turns thereof, and said tie-down arrangement comprising a guide opening disposed between said first connector section and said locking section and through which said second turn of said loop is slidably received wherein pulling of said free rope end pulls said rope through the guide opening to shorten the size of the loop and thereby shorten the distance between the first and second connector sections; and

said free end of said rope extending from said guide opening to define a locking leg which enters into, extends interiorly through and then exits from said locking section to terminate at said free end, said locking leg being slidable through said locking section wherein pulling of said free rope end in a tightening direction tensions said rope to cause said locking section to constrictively grip the portion of said locking leg disposed interiorly therein, wherein said constrictive locking of said rope by said locking section is releasable by longitudinal pulling of said second loop leg in an opposite release direction.

19. The assembly according to claim 18, wherein said first and second legs of said loop extend parallel to each other.

20. The assembly according to claim 19, wherein said first and second turns are disposed adjacent said first and second connector sections and said first and second legs extend longitudinally therebetween.
