Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
257 words
A skip rope comprising: an elongated flexible member; said elongated flexible member including first and second flexible end sections and a flexible first central section intermediate the first and second end sections whereby when the elongated flexible member is put in a generally U-shaped configuration for skipping the first and second end sections form at least substantial segments of the sides of the U and the first central section forms at least a substantial segment of the bottom of the U; each of said end sections having an outer end and an inner end; first and second handles coupled respectively to the outer ends of the first and second end sections; a second flexible central section having at least one characteristic which is different from said first central section; means releasably connecting the inner ends of the first and second end sections to the opposite ends, respectively, of the first central section whereby the first central section can be replaced with the second central section; at least a portion of the first central section being resilient in the axial direction whereby the first central section can be used for exercises other than skipping rope; and said first central section being heavier per unit of length than either of said first and second end sections whereby when the elongated flexible member is put in the U-shaped configuration and swung the relatively heavy bottom of the U tends to get beneath the feet of the user, said end sections being of a different material than said first central section.

A skip rope comprising: an elongated flexible member; said elongated flexible member including first and second flexible end sections and a flexible first central section intermediate the first and second end sections whereby when the elongated flexible member is put in a generally U-shaped configuration for skipping the first and second end sections form at least substantial segments of the sides of the U and the first central section forms at least a substantial segment of the bottom of the U; each of said end sections having an outer end and an inner end; first and second handles coupled respectively to the outer ends of the first and second end sections; a second flexible central section having at least one characteristic which is different from said first central section; means releasably connecting the inner ends of the first and second end sections to the opposite ends, respectively, of the first central section whereby the first central section can be replaced with the second central section; at least a portion of the first central section being resilient in the axial direction whereby the first central section can be used for exercises other than skipping rope; and said first central section being heavier per unit of length than either of said first and second end sections whereby when the elongated flexible member is put in the U-shaped configuration and swung the relatively heavy bottom of the U tends to get beneath the feet of the user, said end sections being of a different material than said first central section.
Claim 3
Dependent Claim
23 words
A skip rope as defined in claim 1 wherein said releasably connecting means is of greater density than any of said end sections.
Claim 4
Dependent Claim
36 words
A skip rope as defined in claim 1 wherein said first central section is less flexible than any of said end sections and tends to maintain the bottom of the U in a relatively wide arc.
Claim 5
Dependent Claim
42 words
A skip rope as defined in claim 3 wherein said releasably connecting means is of greater density than any of said end sections and said first central section is constructed of rubber and each of said end sections is constructed of rope.
Claim 6
Dependent Claim
22 words
A skip rope as defined in claim 1 wherein said first central section is less flexible than any of said end sections.
Claim 7
Dependent Claim
27 words
A skip rope as defined in claim 1 wherein said first central section is constructed of rubber and each of said end sections is constructed of rope.
Claim 8
Dependent Claim
55 words
A skip rope is defined in claim 1 wherein said releasably connecting means includes first and second fastener means releasably attaching said inner ends of the first and second end sections to the opposite ends, respectively, of the first central section, and said first central section is less flexible than either of said end sections.
