Abstract
Abstract An exercise device having a jumprope mounted to a bar by means of rigid standoff rods also has means for receving a selected weight at either end of the bar. A user skipping the jumprope must manipulate both the rope and the weights. The quantity of weight, length of jumprope and the position of hand grips on the bar are all adjustable by the user. In one embodiment, the weights are radially offset from the bar, requiring the user to manipulate an unbalanced weight while skipping the rope.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
147 words
An exercise device, comprising: a bar for grasping intermediate opposite ends thereof, the bar defining an axis; hand grips including tubes rotatable around the bar and means for axially retaining the tubes on the bar; a plurality of weights disposed at said opposite ends of the bar, and means for axially retaining the weights on the bar; a pair of standoff rods, each attachable to the bar by one end and aligned perpendicular to the bar, parallel to one another and spaced from said opposite ends of the bar, the rods having compression fittings at free ends remote from the bar; and a flexible line attaching said stand off rods, the flexible line being attached to said stand off rods at the compression fittings at the free ends thereof, whereby a user can exercise by simultaneously skipping the flexible line and manipulating the bar bearing said weights.
Claim 2
Dependent Claim
147 words
An exercise device, comprising: a bar for grasping intermediate opposite ends thereof, the bar defining an axis; hand grips including tubes rotatable around the bar and means for axially retaining the tubes on the bar; a plurality of weights disposed at said opposite ends of the bar, and means for axially retaining the weights on the bar; a pair of standoff rods, each attachable to the bar by one end and aligned perpendicular to the bar, parallel to one another and spaced from said opposite ends of the bar, the rods having compression fittings at free ends remote from the bar; and a flexible line attaching said stand off rods, the flexible line being attached to said stand off rods at the compression fittings at the free ends thereof, whereby a user can exercise by simultaneously skipping the flexible line and manipulating the bar bearing said weights.
Claim 3
Dependent Claim
22 words
The device of claim 1, wherein said plurality of weights comprise removable incremental weights attachable to the opposite ends of the bar.
Claim 4
Dependent Claim
51 words
The device of claim 1, wherein said means for axially retaining the weight and said means for axially retaining the tube include collars with set screws threadable against the bar, the collars being axially fixed to the bar using the set screws and thereby axially retaining the weights and hand grips.
Claim 5
Dependent Claim
23 words
The device of claim 3, wherein said hand grips are axially fixable at a range of positions along said axis of the bar.
Claim 6
Dependent Claim
46 words
The device of claim 1, wherein said standoff rods are attached to said bar by threaded bolts, the bar having clearance holes aligned perpendicular to its longitudinal axis, the threaded bolts passing through said clearance holes and threadably urging said standoff rods endwise against the bar.
Claim 7
Dependent Claim
25 words
The device of claim 1, wherein said standoff rods are hollow, and adjustably receive a length of said flexible line within said hollow standoff rods.
Claim 8
Dependent Claim
35 words
The device of claim 6, wherein the standoff rods are slotted, tapered and threaded at the end thereof opposite said bar, and wherein the compression fittings comprise a tapered nut threadably fittable on said end.
Claim 9
Dependent Claim
15 words
The device of claim 7, wherein the standoffs rods are at least 8-10 inches long.
Claim 10
Dependent Claim
14 words
The device of claim 8, wherein the standoff rods are about 18 inches long.
Claim 11
Dependent Claim
14 words
The device of claim 1, wherein said flexible line is a solid rubber line.
Claim 12
Dependent Claim
28 words
The device of claim 2, wherein said weights are incremental weight units of about 1-2 pounds, the bar having means for receiving 3-4 weights at each end thereof.
Claim 13
Dependent Claim
33 words
The device of claim 2, wherein the weights are radially spaced from the longitudinal axis of the bar, the user rotating the weights around said longitudinal axis during skipping of the flexible line.
Claim 14
Dependent Claim
13 words
The device of claim 12, wherein the position of said weights is adjustable.
Claim 15
Dependent Claim
