Personal traction device

1. A traction device, comprising:

an elastomeric member;

a cable assembly connected to the elastomeric member and having an elongated segment;

a cleat carried on the segment; the cleat having:

an elongated core through which extends a passage having a central axis, and through which passage fits the segment so that the cleat is rotatably carried thereon;

at least three spaced apart protrusions extending radially from the core and including a first inclined surface on at least one of the protrusions and that is oblique to the central axis of the passage to thereby shape the protrusion such that the protrusion tapers to a first bladed edge.

2. The device of claim 1 wherein two of the spaced apart protrusions extending radially from the core include a second inclined surface thereon that is oblique to the central axis of the passage.

3. The device of claim 2 wherein the second inclined surface on each of the two protrusions shapes the associated protrusion to taper to a bladed edge, thereby to provide at least three bladed edges on the cleat.

4. The device of claim 1 wherein the cleat includes on one of the protrusions a second inclined surface that joins the first inclined surface to shape the protrusion as a wedge having an outermost edge.

5. The device of claim 4 wherein the outermost edge of the wedge is oblique to the central axis of the passage.

6. A traction device, comprising:

an elastomeric member;

a cable assembly connected to the elastomeric member and having an elongated segment;

a cleat carried on the segment; the cleat having:

an elongated core through which extends a passage having a central axis, and through which passage fits the segment so that the cleat is rotatably carried thereon;

wherein the cleat includes four protrusions extending radially from the core and wherein each one of a first pair of the protrusions includes a first inclined surface thereon that is oblique to the central axis of the passage to thereby shape the associated protrusion such that the protrusion tapers to a first bladed edge, and

wherein each one of a second pair of protrusions is shaped to define a wedge having an outermost edge that is oblique to the central axis of the passage.

7. The device of claim 6 wherein the protrusion are configured and arranged to provide a first set of three sharp points in a first common plane for supporting the cleat on a flat surface.

8. The device of claim 7 wherein the protrusions are configured and arranged to provide a second set of three sharp points in a second common plane that is substantially parallel to the first so that the cleat can be stably supported between two surfaces.

9. A traction device, comprising:

an elastomeric member;

a cable assembly connected to the elastomeric member and having an elongated segment;

a cleat carried on the segment; the cleat having:

an elongated core through which extends a passage having a central axis, and through which passage fits the segment so that the cleat is rotatably carried thereon;

a protrusion extending radially from the core and including a first inclined surface thereon that is oblique to the central axis of the passage to thereby shape the protrusion such that the protrusion tapers to a first bladed edge and further comprising spacers threaded on at least one segment and located adjacent to the cleat.

10. The device of claim 9 wherein the spacers are cylindrical and extend from the segment by a distance that is less than the maximum distance that a cleat extends from the segment.

11. The device of claim 1 wherein the passage extends between opposing end faces of the core and wherein the first inclined surface is one of the end faces.

12. The device of claim 1 wherein the cleat is comprised of stainless steel.

13. The device of claim 1 wherein the protrusion includes flat, parallel opposing side surfaces.
