Abstract
Abstract A device for use in performing isometric exercises having a handle and a weight at one end of the handle offset from the longitudinal, turning axis of the handle. The handle defines a plurality of grasping positions for varying the effective torque of the weight relative to the user''s hands. The mass of the weight is selectively adjustable.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
A device for use in isometric exercises, comprising: a manually graspable handle having a grasping portion defining a turning axis and only a single connecting portion turned from said grasping portion; a weight having a preselected mass; and means connecting the weight eccentrically to said handle connecting portion to extend outwardly from the distal end of the handle connecting portion and space the center of said mass from said grasping portion axis beyond the distal end of the connecting portion to provide a preselected torque acting about said axis, said weight comprising a plurality of separable portions at the outer end of the weight spaced from said handle connecting portion for selectively adjusting the spacing of the center of gravity of said mass substantially perpendicularly from said axis while substantially maintaining the spacing of the center of gravity from the grasping portion in a direction parallel to said axis.
Claim 2
Independent Claim
149 words
A device for use in isometric exercises, comprising: a manually graspable handle having a grasping portion defining a turning axis and only a single connecting portion turned from said grasping portion; a weight having a preselected mass; and means connecting the weight eccentrically to said handle connecting portion to extend outwardly from the distal end of the handle connecting portion and space the center of said mass from said grasping portion axis beyond the distal end of the connecting portion to provide a preselected torque acting about said axis, said weight comprising a plurality of separable portions at the outer end of the weight spaced from said handle connecting portion for selectively adjusting the spacing of the center of gravity of said mass substantially perpendicularly from said axis while substantially maintaining the spacing of the center of gravity from the grasping portion in a direction parallel to said axis.
Claim 3
Dependent Claim
33 words
The exercise device of claim 1 including means removably securing said weight portions to each other in a direction substantially perpendicular to said axis permitting the weight to have a selectively variable mass.
Claim 4
Dependent Claim
18 words
The exercise device of claim 1 wherein means are provided for securing said weight portions to each other.
Claim 5
Dependent Claim
26 words
The exercise device of claim 1 wherein means are provided for securing said weight portions to each other in a direction substantially perpendicular to said axis.
Claim 6
Dependent Claim
57 words
The exercise device of claim 1 wherein one weight portion is fixedly secured to said handle connecting portion and a second weight portion is removably secured to said one weight portion by securing means comprising a screw element extending through the removable weight portion and threaded to the weight portion fixedly secured to the handle connecting portion.
Claim 7
Dependent Claim
53 words
The exercise device of claim 1 wherein one weight portion is fixedly secured to said handle connecting portion and a second weight portion is removably secured to said one weight portion by securing means, said one weight portion having a weight of at least approximately four times that of the removable weight portion.
Claim 8
Independent Claim
194 words
A device for use in isometric exercises comprising: a manually graspable handle having a grasping portion defining a turning axis and only a single connecting portion turned from said grasping portion; a weight having a preselected mass; and means connecting the weight eccentrically to said handle connecting portion to extend outwardly from the distal end of the handle connecting portion and space the center of said mass from said grasping portion axis beyond the distal end of the connecting portion to provide a preselected torque acting about said axis, said weight comprising a plurality of separable portions at the outer end of the weight spaced from said handle connecting portion for selectively adjusting the spacing of the center of gravity of said mass substantially perpendicularly from said axis while substantially maintaining the spacing of the center of gravity from the grasping portion in a direction parallel to said axis, said handle grasping portion having a length substantially greater than the width of a user''s hand to permit the user to grasp the handle at any one of a plurality of different positions lengthwise thereof to provide a variable torque acting transversely to said axis.
Claim 9
Independent Claim
194 words
A device for use in isometric exercises comprising: a manually graspable handle having a grasping portion defining a turning axis and only a single connecting portion turned from said grasping portion; a weight having a preselected mass; and means connecting the weight eccentrically to said handle connecting portion to extend outwardly from the distal end of the handle connecting portion and space the center of said mass from said grasping portion axis beyond the distal end of the connecting portion to provide a preselected torque acting about said axis, said weight comprising a plurality of separable portions at the outer end of the weight spaced from said handle connecting portion for selectively adjusting the spacing of the center of gravity of said mass substantially perpendicularly from said axis while substantially maintaining the spacing of the center of gravity from the grasping portion in a direction parallel to said axis, said handle grasping portion having a length substantially greater than the width of a user''s hand to permit the user to grasp the handle at any one of a plurality of different positions lengthwise thereof to provide a variable torque acting transversely to said axis.
Claim 10
Dependent Claim
20 words
The exercise device of claim 7 wherein a soft cover is provided lengthwise of substantially the entire handle grasping portion.
