Abstract
The present invention relates to a shackle. The shackle comprises a shackle body for use with a shackle pin. The shackle body comprises a flexible elongate member comprising at least one length of rope circuitously formed so that the flexible elongate member passes through itself and defines three sequentially adjacent noose portions. Three sequentially adjacent noose portions comprise an intermediate noose portion and two end noose portions at opposing ends of the shackle body.
Claims19
A shackle comprising:
- a shackle body for use with a shackle pin, the shackle body comprising:
- a flexible elongate member comprising at least one length of rope circuitously formed so that the flexible elongate member passes through itself and defines three sequentially adjacent noose portions, wherein the at least one length of rope defines a continuous endless circuit, and the flexible elongate member passes through itself at two intersections of itself.
A shackle body for use with a shackle pin, the shackle body comprising:
- a flexible elongated member comprising of at least one length of rope arranged as a continuous endless loop that is double twisted and defining between two ends of the loop a first notional section of said elongated member and a second notional section of said elongated member,
- wherein:
- at a first twist of the loop the first section of said elongated member passes through a parting of the second section, and
- at the second twist of the loop the second section of said elongated member passes through a parting of the first section.

A shackle comprising:
- a shackle body for use with a shackle pin, the shackle body comprising:
- a flexible elongate member comprising at least one length of rope circuitously formed so as to define a continuous endless circuit such that the flexible elongate member passes through itself at two intersections of itself and defines three sequentially adjacent noose portions comprising an intermediate noose portion and two end noose portions at opposing ends of the shackle body, wherein:
- (i) a first intersection of the two intersections defines a transition of the flexible elongate member from the intermediate noose portion to a first end noose portion of the two end noose portions, and a second intersection of the two intersections defines a transition of the flexible elongate member from the intermediate noose portion to a second end noose portion of the two end noose portions, and
- (ii) a contraction or extension of the intermediate noose portion causes a movement of said length of rope through the two intersections, thereby effecting a proportional tightening or loosening of one or each of said end noose portions such that when the shackle pin is used with the shackle, and extends through eyes defined by the end noose portions, a tightening of said end noose portions promotes a contraction of said eyes about said shackle pin and a corresponding coupling of the shackle pin to the shackle body.
