An apparatus for attaching a jump rope to a pair of handweights which has a C-shaped adapter which accommodates the full range of detachable weights normally used with aerobic handweights such as the "Heavy Hands" handweights of AMF Industries. The C-shaped adapter slips over the threaded extension on one end of each handweight and is held in place by the detachable weight after it is screwed down over the threaded extension. The C-shaped adapter has an upper portion in which a pressed fit bearing accommodates and retains one extreme end of the jump rope and has a lower portion having a circular opening for slidably attaching each C-shaped adapter to one of the respective handweights. A middle portion of the C-shaped adapter holds the upper and lower portions of the C-shaped adapter in a parallel relationship to one another and the dimensions of the C-shaped adapter are such that its three portions clear the depth and diameter of each of the range of detachable weights. Retainer clips on either end of the jump rope hold it within the C-shaped adapter and a resilient washer, permanently affixed to the inside of the lower portion of the C-shaped adapter, assure a tight fit for the detachable weight.
A jump rope apparatus, in combination with a pair of aerobic handweights having an elongate handle with two ends and threaded extensions protruding longitudinally from each end connectable to a full range of detachable weights, comprising:

(1) Field of Invention
This invention relates generally to jump ropes used in exercise and ore particularly to apparatus for attaching a jump rope to a pair of aerobic handweights having a range of detachable weights.
(2) Description of Prior Art
FIG. 1 is a perspective view from the right front of the jump rope apparatus constructed in accordance with the principles of the present invention, showing the manner in which it attaches to a pair of aerobic handweights.
FIG. 2 is a plan view of the same present invention showing the upper portion of the C-shaped adapter which houses the pressed fit bearing.
FIG. 3 is a fragmentary side elevational view of the present invention taken substantially along line 3--3 of FIG. 2 showing how the C-shaped adapter fastens between the handweight and the detachable weight.
The jump rope apparatus is a compact, relatively small unit, which is easily attached to or detached from a pair of aerobic handweights, allowing a range of detachable weights to be used without disturbing the jump rope apparatus. Throughout the following detailed description of the present invention, like reference numerals are used to denote like parts disclosed in the accompanying drawings, FIGS. 1-4.
As shown in FIG. 1, the jump rope apparatus, shown generally at reference numeral 10, is designed to attach to one end of a pair of aerobic handweights, shown generally at reference numerals 11. The basic structure of aerobic handweights usually comprises a handle 12, a retaining strap 13 and two threaded extensions 14 and 15. The handweights 11, usually each weigh about a pound and a range of additional detachable weights, such as 16 and 17, are furnished with aerobic handweights 11 to bring each such handweight up to a higher total weight. The aerobic handweight 11, shown in FIGS. 1 and 3, is typical of the most popular handweights, manufactured and marketed by AMF Industries under the trademark "Heavy Hands". At the present time AMF Industries furnishes 9 sets of extra detachable weights, each such weight increasing the weight of the handweight by a pound, the largest weights bringing the total weight of the handweight to 10 pounds. The detachable weights, such as 16 and 17, screw onto threaded extensions 14 and 15 shown on both ends of handweight 11 in FIG. 3.
The Jump rope apparatus of the present invention is for use with a pair of aerobic handweights, such as described above, which have a range of detachable weights. The jump rope apparatus comprises a jump rope 18, preferably made of 1/4 inch top grain leather cord or waterproof nylon, and a connector means, shown generally at reference numeral 19, for attaching jump rope apparatus 10 to aerobic handweights 11. Jump rope apparatus 10 also has a swivel means, shown generally at reference numeral 20 for attaching jump rope 18 to connector means 19 so that jump rope 18 can rotate freely in a b 360 degree arc.
