Abstract

The invention consists of a flexible hexagonal array composed of rigid plastic rings, sized and shaped for convenient gripping with the hands, and or pinning against floor or wall by other body parts (feet, knees, elbows, trunk, bead, etc.) each connected to 3 to 6 lengths of bungee, or equivalent elastic material, located at 60 degree intervals around the ring circumference. The array is sized for convenient use for exercise purposes, and is light enough to be readily portable, and, by virtue of its uniform stretch resistance properties, which vary with the number of strands being stretched, and the distance between gripping and/or pinning points, which controls the length of bungee being stretched, gives the opportunity of exercising all of the skeletal muscles, at a variety of resistance levels.

Claims

1. An elastic resistance exercising apparatus for exercising skeletal muscles wherein said device comprises a plurality of equilateral triangular elements assembled to form a configuration and wherein each of said plurality of equilateral triangular elements comprises a tension element forming the sides thereof and a puck assembly at each corner thereof.

3. The apparatus of claim 1 wherein the configuration is a parallelogram.

4. The apparatus of claim 1 wherein the configuration is a polygon.

5. The apparatus of claim 1 wherein the configuration is a hexagon.

6. The apparatus of claim 1 wherein said tension element comprises a length of shock cord having a first end and a second end wherein said first end and said second end are anchored to a respective first puck assembly and a second puck assembly by a respective first and second rectangular prisms.

7. The apparatus of claim 6 wherein the shock cord first end and second end include a first end loop and a second end loop and wherein said first and second end loops are fixed in place by a metallic crimp.

8. The apparatus of claim 7 wherein said first and second rectangular prisms comprise a frustoconical aperture from a top surface of the first and second rectangular prism to the bottom surface of the rectangular prism.

9. The apparatus of claim 8 wherein said frustoconical aperture of the first and second rectangular prism accepts the first and second loops therein thereby providing an anchor for the tension element first and second ends.

10. The apparatus of claim 1 wherein said puck assembly comprises an assembly top half and an identical assembly bottom half press fit together.

11. The apparatus of claim 10 wherein said assembly top half comprises a disc-shaped body having a downwardly curved upper surface having a bottom edge having a circumference and a bottom surface.

12. The apparatus of claim 11 wherein said bottom edge includes a plurality of archways disposed equally around said circumference and wherein each of said plurality of archways has a radius equal to a radius of the tension element.

13. The apparatus of claim 12 wherein said bottom surface includes a plurality of chambers adapted to receive one of the first and second rectangular prisms in a press-fit relationship.

14. The apparatus of claim 13 wherein the bottom surface further comprises, alternatively, a pair of projections and a pair of receiving apertures that straddle the archways so that when the assembly top half is press fit with the assembly bottom half said pair of projections of the assembly top half mate with said receiving apertures of the assembly bottom half.

2. The apparatus of claim wherein said configuration is a triangle.

15. An elastic resistance exercising apparatus for exercising skeletal muscles wherein said device comprises a plurality of equilateral triangular elements assembled to form a configuration and wherein each of said plurality of equilateral triangular elements comprises a tension element forming the sides thereof and a puck assembly at each corner thereof;

wherein,

a. said tension element comprises a length shock cord having a first end and a second end wherein said first end and said second end are anchored to a respective first puck assembly and a second puck assembly by a respective first and second rectangular prisms;

b. the shock cord first end and second end include a first end loop and a second end loop and wherein said first and second end loops are fixed in place by a metallic crimp;

c. said first and second rectangular prisms comprise a frustoconical aperture from a top surface of the first and second rectangular prism to the bottom surface of the rectangular prism;

d. said frustoconical aperture of the first and second rectangular prism accepts the first and second loops therein thereby providing an anchor for the tension element first and second ends;

e. said puck assembly comprises an assembly top half and an identical assembly bottom half press fit together.

16. The apparatus of claim 15 wherein said assembly top half comprises a disc-shaped body having a downwardly curved upper surface having a bottom edge having a circumference and a bottom surface and wherein said bottom edge includes a plurality of archways disposed equally around said circumference and wherein each of said plurality of archways has a radius equal to a radius of the tension element.

17. The apparatus of claim 16 wherein said bottom surface includes a plurality of chambers adapted to receive one of the first and second rectangular prisms in a press-fit relationship and wherein the bottom surface further comprises, alternatively, a pair of projections and a pair of receiving apertures that straddle the archways so that when the assembly top half is press fit with the assembly bottom half said pair of projections of the assembly top half mate with said receiving apertures of the assembly bottom half.
