Abstract
Abstract A rope-jumping device that will provide exercise and entertainment for users in jumping, having a U-shaped rod structure with a bowed end rod and depending rod members that diverge outwardly to clear the sides of the user, and a flexible line secured to the ends of the rod members, which device is manipulated by the hands of the user on the bowed end rod to cause the flexible line to rotate over the head and under the feet of the user.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
A rope-jumping device for being manipulated by a user comprising, a U-shaped structure solely comprising an end rod and a pair of depending rod members, said rod members having a space therebetween sufficient to receive a user, a flexible line connected between the ends of said rod members, the distance between a midportion of said line and said end rod being greater than the height of a child user, said line has a midportion with a length substantially equal to the length of said end rod, and said midportion of said line and said end rod being spaced substantially equal distances from the connection of the ends of said line to the ends of said rod members.
Claim 2
Dependent Claim
117 words
A rope-jumping device for being manipulated by a user comprising, a U-shaped structure solely comprising an end rod and a pair of depending rod members, said rod members having a space therebetween sufficient to receive a user, a flexible line connected between the ends of said rod members, the distance between a midportion of said line and said end rod being greater than the height of a child user, said line has a midportion with a length substantially equal to the length of said end rod, and said midportion of said line and said end rod being spaced substantially equal distances from the connection of the ends of said line to the ends of said rod members.
Claim 3
Dependent Claim
119 words
A rope-jumping device for being manipulated by a user comprising, a U-shaped structure solely comprising an end rod and a pair of depending rod members, said rod members having a space therebetweeN sufficient to receive a user, a flexible line connected between the ends of said rod members, the distance between a midportion of said line and said end rod being greater than the height of a child user, said rod members and said end rods are in the same plane, said rod members diverge outwardly at a slight angle from each other, and said end rod is bowed outwardly along its length in a direction away from said rod members to facilitate rotational movement by a user''s hands.
Claim 4
Dependent Claim
119 words
A rope-jumping device for being manipulated by a user comprising, a U-shaped structure solely comprising an end rod and a pair of depending rod members, said rod members having a space therebetweeN sufficient to receive a user, a flexible line connected between the ends of said rod members, the distance between a midportion of said line and said end rod being greater than the height of a child user, said rod members and said end rods are in the same plane, said rod members diverge outwardly at a slight angle from each other, and said end rod is bowed outwardly along its length in a direction away from said rod members to facilitate rotational movement by a user''s hands.
Claim 5
Dependent Claim
59 words
A rope jumping device as claimed in claim 2 in which, in use said end rod has an axis of rotation when manipulated by a user, and said bowed condition comprising a bend in said end rod at its midpoint with each end portion of said end rod extending at about a 12* angle from said axis of rotation.
Claim 6
Dependent Claim
26 words
A rope-jumping device as claimed in claim 3 in which, said rod members diverge outwardly from perpendicular to said axis of rotation at about 5* angle.
Claim 7
Dependent Claim
32 words
A rope-jumping device as claimed in claim 1 in which, the ends of said flexible line overlapping the ends of said rod members, and removable band means for securing said ends together.
Claim 8
Dependent Claim
26 words
A rope-jumping device as claimed in claim 1 in which, the ends of said rod members having eyelet means for receiving the ends of said line.
