SKIP ROPE Filed Feb. 16, 1959 INVENTOR. wasp/w 0N0 BY 79 W *M HIS ATTORNEYS 3,075,767 SK]? ROPE Noboru Ono, 2448 Acton St., Berkeley, Calif. Filed Feb. 16, 1959, Ser. No. 793,440 4 Claims. (Cl. 272-75) My invention relates to the field of toys and more particularly to a skip rope.

A skip rope as generally known, is made up of a length of conventional rope with a handle at each end. Use of conventional rope can often result in sharp stinging blows if a child be accidentally struck thereby, or if employed in high jump activity can cause tripping of a participant should be fail to clear the rope, and bring about a resulting injury.

Among the objects of my invention are:

(1) To provide a novel and improved skip rope;

(2) To provide a novel and improved skip rope which shall be safe and harmless to use;

(3) To provide a novel and improved skip rope which shall appeal to youngsters;

(4) To provide a novel and improved skip rope which lends itself to various appealable color combinations in the manufacture thereof.

Additional objects of my invention will be brought out in the following description of a preferred embodiment of the same, taken in conjunction with the accompanying drawing, wherein:

The FIGURE is a three dimensional view of a preferred embodiment of my invention and is illustrative of the fundamental principles underlying the same.

In lieu of utilizing the conventional rope or something comparable in structure thereto, I form my skip rope of a plurality of weight elements coupled by intermediate links of flexible stretchable or elastic material, and terminate the resulting assembly at each end with a suitable handle.

Referring to the drawing for specific details of my invention in its preferred form, the weight elements may each take the form of a relatively thick ring 1 of material such as rubber or the like which possesses resiliency, and these are coupled to interlinking elastic loops 3, possessing considerable flexibility and substantial elasticity. The asembly of the heavier ring elements and interlinking elastic bands is preferably terminated with one of the ring elements which then permits linking therewith of a ring 5 of plastic or the like of substantially greater diameter to function as a handle.

By forming the skip rope in the manner indicated, that is by means of a plurality of weight elements coupled by intermediate links of flexible stretchable elastic material, the skip rope may be used by youngsters With safety, for the tension developed in the elastic links during use ice of the skip rope as such, will tend to retract the weight elements should the rope strike a child while in use, and thus serve to cushion the effect of the blow. The fact that the Weight elements themselves may be of rubber or other resilient material will further serve to cushion any blow resulting from the rope striking an individual.

Further, should the rope be employed for high jump purposes, any failure on the part of a participant to clear the rope is not likely to result in tripping up the participant, for the rope will give and permit the participant to land safely and without falling.

My new skip rope in addition to the forgoing advantages, lends itself to an assembly of its many components into a Wide variety of attractive color combinations.

While I have disclosed my invention in its preferred form, it will be apparent that the same lends itself to alteration and modification without departing from the underlying principles involved. The weight elements might be in the form of rubber balls for example, while the elastic coupling links might be in the form of single thick strands. Or any other arrangement which will bring about a skip rope having the equivalent of a plurality of Weight elements coupled by flexible stretchable links will fulfill the requirements of my invention.

I accordingly do not desire to be limited in my protection to the specific details thus illustrated and described, except as may be necessitated by the appended claims.

I claim:

1. A skip rope comprising a plurality of non-metallic weight elements coupled by intermediate links of flexible stretchable material, and a handle at each end.

2. A skip rope comprising a plurality of non-metallic weight elements, each involving a relatively thick ring, said rings being coupled by intermediate links of flexible stretchable material, and a handle at each end.

3. A skip rope comprising a plurality of resilient rubber-like Weight elements coupled by intermediate elastic bands, and a handle at each end.

4. A skip rope comprising a plurality of weight elements each involving a relatively heavy ring of resilient rubber-like material, said rings of resilient nibber-like material being interlinked by intermediate elastic bands, and a handle at each end.
