Abstract
A multi-use exercise device having an elastic, flexible line with a length sufficient for an operator to use the line as a jump rope. A pair of rigid handles are attached to free ends of the lines. The handles are attachable to form a longitudinal composite handle. A pair of rings are carried on free ends of the handle and are sized to be received on the line when the line is folded onto itself with the ring slipped over the fold and retaining the line in the folded position to thereby shorten the length or modify the shape of the line.
Claims9
An exercise apparatus, comprising:
- an elastic flexible line having a length sufficient for an operator to use said line as a jump rope;
- a pair of rigid handles including a first handle and a second handle each having a line receiving end and a longitudinally displaced handle attching end, each of said handles including means for releasably attaching said handle with the other of said handles at said handle attaching ends to form a composite handle with said line receiving ends longitudinally displaced;
- means for rotatatably securing ends of said line to said line receiving ends;
- and
- means for releasably holding said line in a folded position so as to create loops at opposite ends of the folded line, said means for releasably holding said line including means surrounding said line and having an inside dimension sized for said surrounding means to freely pass along said line and resistively pass along said folded line.

An exercise apparatus, comprising:
- an elastic flexible line have a length sufficient for an operator to use said line as a jump rope;
- a pair of rigid cylindrical handles including a first cylindrical handle and a second cylindrical handle each having a line receiving end and an axially displaced handle attaching end;
- means for releasably attaching said handles at said handle attaching ends with said handles axially aligned to form a composite cylindrical handle and with said line receiving ends disposed on axially aligned opposite ends of said composite handle;
- means for securing ends of said line to said line receiving ends;
- a pair of flexible rings surrounding said line with said rings having an inside diameter sized for said rings to freely pass over a single strand of said line but sized to resistively pass over a folded line;
- said handle attaching ends having outside dimensions sized slightly greater than an inside dimension of said rings.

A method of using an exercise apparatus having an elastic flexible line having a length sufficient for an operator to use said line as a jump rope;
- a pair of rigid handles each having a line receiving end and a longitudinally displaced handle attaching end;
- means for releasably attaching said handles at said handle attaching ends to form a composite handle with said line receiving ends longitudinally displaced;
- means for securing ends of said line to said line receiving ends;
- and ring lock means for holding said line in a folded position with said folded line having a reduced length between said line receiving ends with said ring lock means including a pair of rings having inside diameters for said rings to freely pass over said line and resistably pass over a folded line;
- the method comprising the steps of:
- attaching said handles at said handle attaching ends to form a composite handle;
- folding a portion of said line to provide a first loop and a second loop;
- urging a first ring along said line and over said first loop with said first ring surrounding said folded line adjacent said first loop and urging said second ring along said line and over said second loop;
- resistively passing said folded line through said rings to adjust a total length of said line between the line receiving ends of said handles to a desired length for said line to engage a portion of said operator's body with said operator engaging said composite handle;
- and
- exercising said body portion by relatively moving said portion away from said handle against a resilient resistance of said line.
