Abstract

A simple and inexpensive device for a reliable tie down tensioning which device enables the tie-down to be quickly and easily applied and the flexible element tensioned and just as quickly and easily removed.

Claims (20)

1. A device for holding a flexible elongated element under tension, said device comprising:
a housing comprising first and second opposed side walls;
a channel within said housing, said channel defined between said first and second opposed side walls;
extending around a wheel between first and second openings in said housing;
and configured for guiding said flexible elongated element through said housing and around said wheel when a portion of said flexible elongated element moves between said first and second openings;
a jamming cleat configured for receiving and engaging said flexible elongated element extending through said channel;
a locking element configured for inhibiting disengagement of said flexible elongated element engaged within said jamming cleat; and an aperture extending through said housing, said aperture configured for receiving a removable securing element extending through said housing for attaching said device to a substantially fixed object.
2. The device of claim 1, wherein a hub of said wheel rotatably engages opposing cylindrical extensions, said cylindrical extensions extending from said first and second opposed side walls; and aligned to function as an axle for said wheel.
3. The device of claim 1, wherein said aperture aligns with a hub of said wheel nested between said first and second opposed side walls and wherein said securing element extending through said housing rotatbly engages the hub of said wheel and functions as an axle for said wheel.
4. The device of claim 1, wherein a movement of said flexible elongated element between said first and second openings imparts a rotational movement on said wheel such that there is essentially no slippage between said wheel and said flexible elongated element.
5. The device of claim 4, further comprising a wheel locking mechanism configured for permitting said wheel to rotate essentially uninhibited in a first direction in conjunction with a movement of said flexible elongated element in said first direction such that there is essentially no slippage between said wheel and said flexible elongated element; and inhibiting said wheel to rotate in a second direction opposite said first direction, thereby impairing movement of said flexible elongated element in said second direction.
6. The device of claim 1, further comprising two or more apertures extending through said housing wherein each aperture is configured for receiving at least one additional removable securing element extending through said housing.
7. The device of claim 6, wherein each securing element comprises at least one retention mechanism configured for inhibiting removal of said securing element from said aperture, said retention mechanism selected from the group consisting of spring clip, cotter pin, hair pin, clevis pin, nut, rivet, and securing element structural feature.
8. The device of claim 6, wherein each securing element comprises at least two retention mechanisms with at least one of said retention mechanisms on each side of said housing such that movement of said device is restricted to between said retention mechanisms, said retention mechanisms selected from the group consisting of spring clip, cotter pin, hair pin, clevis pin, nut, rivet, and securing element structural feature.
9. The device of claim 1, wherein said wheel is a pulley and said device is part of a configuration selected from the group consisting of block, tackle, and block and tackle.
10. A method of using a device for holding a flexible elongated element under tension, said method comprising:
providing said device comprising a housing comprising first and second opposed side walls;
a channel within said housing, said channel defined between said first and second opposed side walls;
extending around a wheel between first and second openings in said housing; and configured for guiding said flexible elongated element through said housing and around said wheel when a portion of said flexible elongated element moves between said first and second openings;
a jamming cleat configured for receiving and engaging said flexible elongated element extending through said channel;
a locking element configured for inhibiting disengagement of said flexible elongated element engaged within said jamming cleat; and an aperture extending through said housing;
extending a removable securing element through said aperture in said housing and attaching said device to a substantially fixed object;
inserting an end of said flexible elongated element through said first opening;
feeding said end of said flexible elongated element through said channel and around said wheel;
extracting said end of said flexible elongated element through said second opening;
tensioning said end of said flexible elongated element and extracting a portion of said flexible elongated element through said second opening until a desired tension is achieved; and engaging said portion of said flexible elongated element extracted through said second opening in said jamming cleat first, next relaxing said tensioning on an end section of said flexible elongated element, and then engaging said end section in said locking element, wherein said end section is that portion of said flexible elongated element between said end and said jamming cleat.
11. The method of claim 10, comprising affixing a load to a portion of said flexible elongated element extending from said first opening and external to said housing, wherein said load is affixed before the steps of tensioning, engaging and relaxing.
12. The method of claim 11, wherein the step of tensioning precedes the steps of engaging and relaxing.
13. The method of claim 11, comprising operating said device as part of a configuration selected from the group consisting of block, tackle, and block and tackle.
14. The method of claim 11, comprising releasing said flexible elongated element from tension by first disengaging said end section from said locking element and then disengaging said flexible elongated element from said jamming cleat.
15. The method of claim 10, comprising imparting a rotational movement on said wheel in conjunction with a movement of said flexible elongated element between said first and second openings such that there is essentially no slippage between said wheel and said flexible elongated element.
16. The method of claim 10, wherein said device comprises a wheel locking mechanism configured for permitting said wheel to rotate essentially uninhibited in a first direction in conjunction with a movement of said flexible elongated element in said first direction such that there is essentially no slippage between said wheel and said flexible elongated element; and inhibiting said wheel to rotate in a second direction opposite said first direction, thereby impairing movement of said flexible elongated element in said second direction.
17. A device for holding a flexible elongated element under tension, said device comprising:
a housing comprising first and second opposed side walls;

a channel within said housing, said channel defined between said first and second opposed side walls;
extending from a first opening in said housing, through an approximately 180°
turn, to a second opening in said housing; and including means for reducing friction as a portion of said flexible elongated element moves from said first opening to said second opening;
a jamming cleat configured for receiving and engaging said flexible elongated element extending through said channel;
a locking element configured for inhibiting disengagement of said flexible elongated element engaged within said jamming cleat; and an aperture extending through said housing, said aperture configured for receiving a removable securing element extending through said housing for attaching said device to a substantially fixed object.
18. The device of claim 17, wherein said means for reducing friction comprises a wheel, wherein a hub of said wheel rotatably engages means for supporting said wheel.
19. The device of claim 17, wherein means for reducing friction is nested between said first and second opposed side walls.
20. The device of claim 17, wherein a movement of said flexible elongated element between said first and second openings imparts a rotational movement on said means for reducing friction such that there is essentially no slippage between said means for reducing friction and said flexible elongated element.
