Abstract
Abstract An exercising device for strengthening and developing the hand, wrist, forearm and pectoral muscles. The device includes an elongated rotating pin having a central portion with a circular cross-section and gripping portions located on either side of and coaxial with the central portion. The central portion is received by a clamping mechanism which is held stationary by a mounting apparatus. The clamping mechanism includes an adjustment for varying the frictional force exerted by the clamp on the rotating member. Further included is a laminated liner disposed between the clamping mechanism and the rotating member comprised of a layer of rubber and a layer of self-lubricating plastic.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
137 words
An exercise device comprising: an elongated rotatable member having a central portion with a generally circular cross-section and a gripping portion located on either side of said central portion; a clamping mechanism which encircles a substantial part of said central portion; mounting means for preventing rotation of said clamping mechanism when said elongated member is rotated; a liner disposed between said clamping mechanism and said central portion of said elongated member, said liner including a layer of resilient material adjacent said clamping mechanism and a layer of material having a relatively low coefficient of friction adjacent said central position; and adjustment means for tightening and loosening said clamping mechanism; whereby an operator can exercise by grasping said gripping portions and rotating said elongated member with the resistance of rotation being adjustable by way of said adjustment means.
Claim 2
Dependent Claim
