Abstract
Abstract A segmented jump rope having handles is provided with soft, flexible sleeves overlappable with the handles and slidable to the center of the rope. The sleeves may have abutting ends, or one sleeve may be configured to mate within the adjacent end of the other. The segments of the rope are shorter than either sleeve, but the central segments may be longer and of greater diameter than the others for improved interaction with the sleeves to straighten the central arc of the rope.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
208 words
An improved jump rope of the kind having a flexible core extending continuously between handles on each of the opposite ends of the rope to form the body thereof, and having a plurality of elongated tubular segments slidable over the core between the handles, the segments having substantially similar inner diameters for non-telescoping adjacent positioning along the length of the core, wherein the improvement comprises: (a) each of said handles having an outer diameter larger than that of the tubular segments; and (b) first and second sleeves, one slidably mounted on each of said handles and covering a substantial portion of the handle for hand engagement with each said handle means on the outer end thereof to prevent the associated sleeve sliding off the outer end thereof, each sleeve having an inner diameter larger than the outer diameter of the handle for permitting the sleeves to be selectively slidable onto the body of the jump rope to positions near the center thereof over said tubular segments for centrally weighting the body of the rope, the length of each sleeve being greater than the length of each elongated segment for holding the segments in alignment through a portion of the body longer than the length of an individual segment.
Claim 2
Dependent Claim
208 words
An improved jump rope of the kind having a flexible core extending continuously between handles on each of the opposite ends of the rope to form the body thereof, and having a plurality of elongated tubular segments slidable over the core between the handles, the segments having substantially similar inner diameters for non-telescoping adjacent positioning along the length of the core, wherein the improvement comprises: (a) each of said handles having an outer diameter larger than that of the tubular segments; and (b) first and second sleeves, one slidably mounted on each of said handles and covering a substantial portion of the handle for hand engagement with each said handle means on the outer end thereof to prevent the associated sleeve sliding off the outer end thereof, each sleeve having an inner diameter larger than the outer diameter of the handle for permitting the sleeves to be selectively slidable onto the body of the jump rope to positions near the center thereof over said tubular segments for centrally weighting the body of the rope, the length of each sleeve being greater than the length of each elongated segment for holding the segments in alignment through a portion of the body longer than the length of an individual segment.
Claim 3
Dependent Claim
33 words
The jump rope of claim 1, wherein each of said sleeves further comprises mating means for joining the sleeves in axial alignment when the sleeves are positioned near the center of the rope.
Claim 4
Dependent Claim
41 words
The jump rope of claim 1, wherein said first sleeve has an inner diameter of predetermined size and said second sleeve has an end portion of smaller diameter than said predetermined size for insertion into the end of the first sleeve.
Claim 5
Dependent Claim
55 words
The jump rope of claim 1, wherein said sleeves are constructed of a resilient material for cushioning the handles when the sleeves are mounted thereon and for retaining the sleeves on the handles through deformation under the pressure of being gripped, and wherein said handles extend for substantially at least the length of the sleeves.
Claim 6
Dependent Claim
71 words
The jump rope of claim 1, further comprising a central segment of said elongated body and a plurality of outer segments located relatively nearer the ends of the elongated body, wherein the central segment has a greater axial length than any of the outer segments for interacting with said sleeves when slidably moved to said positions near the center of the elongated body to hold the sleeves in improved axial alignment.
Claim 7
Dependent Claim
71 words
The jump rope of claim 1, further comprising a central segment of said elongated body and a plurality of outer segments located relatively nearer the ends of the elongated body, wherein the central segment has a greater outer diameter than any of the outer segments for interacting with said sleeves when slidably moved to said positions near the center of the elongated body to hold the sleeves in improved axial alignment.
Claim 8
Dependent Claim
75 words
The jump rope of claim 1, wherein said handles comprise a cylindrical grip portion having a flared end thereon, the handles being strung on the core with the flared ends at the outside extremes thereof, the grip portion of the handle having a greater outer diameter than said segments; and wherein said sleeves have an inner diameter greater than the diameter of said grip portions but smaller than the maximum diameter of the flared ends.
