Eccentric rotatable weight exercising device

Claim 2

An exercise device for improving muscle tone comprising: a cross shaft; a pair of hand grips encircling the ends of said cross shaft positioned so as to maintain an exerciser's arms substantially parallel; means to eccentrically weight said cross shaft including a hollow elongated weight of deformable plastic non-rotatably secured to each end of said cross shaft by spherical connector members non-rotatably secured to the ends of said cross shaft and adapted to removably receive the ends of said elongated weights therein, each weight forming an obtuse angle with said cross shaft sufficient to clear the body of the exerciser.

Claim 3

The device of claim 1, wherein each end of said cross shaft is provided a protrusion having at least one flat portion; and an opening in said connector member and having a cross sectional profile adapted to receive said protrusion non-rotatably therein.

Claim 4

The device of claim 1, wherein each of said connector members is composed of deformable plastic and includes a threaded fastener means for removably securing an end of one of said elongated weights therein.

Claim 5

The device of claim 1, wherein said connector members and said elongated weights are soft and deformable plastic.

Claim 6

An exercise device for improving muscle tone comprising: a cross shaft; a hand grip encircling the cross shaft mid-way from its opposite ends; hollow elongated weights of deformable plastic non-rotatably secured to each end of said cross shaft by means of spherical connector members non-rotatably secured to the ends of said cross shaft and adapted to removably receive the ends of said elongated weights, each weight forming an obtuse angle with said cross shaft sufficient to clear the body of the exerciser; and clearance between said cross shaft and said hand grip to permit orbital movement of said cross shaft within said hand grip, wherein circular motion of said hand grip causes said cross bar to orbit within said hand grip eccentric to the center line of said hand grip.

Claim 7

An exercise device for improving muscle tone comprising: a cross shaft; a hand grip encircling the cross shaft mid-way from its opposite ends; hollow elongated weights of deformable plastic non-rotatably secured to each end of said cross shaft by means of spherical connector members non-rotatably secured to the ends of said cross shaft and adapted to removably receive the ends of said elongated weights, each weight forming an obtuse angle with said cross shaft sufficient to clear the body of the exerciser; and clearance between said cross shaft and said hand grip to permit orbital movement of said cross shaft within said hand grip, wherein circular motion of said hand grip causes said cross bar to orbit within said hand grip eccentric to the center line of said hand grip.

Claim 8

An exercise device for improving muscle tone, said device comprising: an elongated shaft-like frame member having two spaced ends and two generally cylindrical gripping portions adjacent said ends; elongated, generally tubular hand grips journalled around said gripping portions whereby said frame member may rotate within said hand grips; each of said cylindrical gripping portions having a selected diameter; and two weighting means for eccentrically weighting said frame member; one of said weighting means being adjacent each of said spaced ends, each of said weighting means comprising an intermediate coupling element having a first coupling means for fixedly and non-rotatably coupling said element to said frame member at one of said spaced ends with said frame member extending along a first direction from said coupling element and second coupling means on said coupling element for coupling to an elongated hollow plastic receptacle having an elongated axis and an opening generally aligned with said axis, said opening having an inside diameter, said inside diameter being greater than said selected diameters whereby said receptacles can be telescoped over said gripping portions; said elongated receptacle extending along a second direction from said coupling element, the included angle between said first and second directions being greater than 90°.

Claim 9

An exercise device for improving muscle tone, said device comprising: an elongated shaft-like frame member having two spaced ends and two generally cylindrical gripping portions adjacent said ends; elongated, generally tubular hand grips journalled around said gripping portions whereby said frame member may rotate within said hand grips; each of said cylindrical gripping portions having a selected diameter; and two weighting means for eccentrically weighting said frame member; one of said weighting means being adjacent each of said spaced ends, each of said weighting means comprising an intermediate coupling element having a first coupling means for fixedly and non-rotatably coupling said element to said frame member at one of said spaced ends with said frame member extending along a first direction from said coupling element and second coupling means on said coupling element for coupling to an elongated hollow plastic receptacle having an elongated axis and an opening generally aligned with said axis, said opening having an inside diameter, said inside diameter being greater than said selected diameters whereby said receptacles can be telescoped over said gripping portions; said elongated receptacle extending along a second direction from said coupling element, the included angle between said first and second directions being greater than 90°.

Claim 10

An exercise device as deined in claim 6 including two hand grips wherein said hand grips have an outer major transverse dimension, said transverse dimension being less than said inside diameter of said receptacles.

Claim 11

An exercise device for improving muscle tone comprising: a cross shaft having two ends; protrusions on each end of said cross shaft with non-circular cross sections extending along the axis of the cross shaft; a pair of hand grips encircling said cross shaft positioned so as to maintain an exerciser's arms substantially parallel; hollow elongated members to eccentrically weight said cross shaft; and connector means comprising a housing encircling the terminal free end portion of the shaft protrusion for non-rotatably securing said elongated members to said cross shaft, said connector means having an aperture of the same non-circular cross section as said cross shaft protrusions.

Claim 12

An exercise device for improving muscle tone comprising: a cross shaft having two ends; protrusions on each end of said cross shaft with non-circular cross sections extending along the axis of the cross shaft; a pair of hand grips encircling said cross shaft positioned so as to maintain an exerciser's arms substantially parallel; hollow elongated members to eccentrically weight said cross shaft; and connector means comprising a housing encircling the terminal free end portion of the shaft protrusion for non-rotatably securing said elongated members to said cross shaft, said connector means having an aperture of the same non-circular cross section as said cross shaft protrusions.

Claim 13

The device of claim 8, wherein said cross shaft protrusions have wedge shaped snap lips which penetrate said aperture and secure said connector means against disassembly from said cross shaft.

Claim 14

The device of claim 9, wherein said elongated members are threadably secured to said connector means at an obtuse angle to said cross shaft.

Claim 15

The device of claim 10, wherein said elongated members have openings aligned with the longitudinal axis of said elongated members, said openings having a diameter greater than the diameter of said cross shaft or said hand grips whereby said elongated members may be telescoped over said cross shaft.
