Abstract
Abstract An exercising apparatus has two hand grips each of which is in the form of a U-shape having two substantially parallel end portions. A pin extends between the end portions and is detachably connected to the latter. A variable number of elastic closed bands or loops enclose each of the pins so as to normally engage the pins of the hand grips when the hand grips are separated from one another by a person performing an exercise. The number of loops or bands, in the form of rubber bands, can be changed by removing the pins from the hand grips and disengaging one or more of the bands. The flexibility in which the exercising apparatus may be utilized is enhanced by securely connecting one of the hand grips to a flat, substantially rigid board. The board may be clamped to a flat supporting surface and cushioning means in the form of a foam pad may be positioned on the flat board when the apparatus is utilized for hand wrestling exercises. Alternately, a person can stand on the board and do back and leg exercises.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
211 words
An exercising apparatus comprising first and second gripping means each provided with two parallel end portions to define first and second U-shaped grip members respectively, first pin means extending between said end portions of said first grip member with opposite ends of said first pin means being removably connected to said end portions of said first grip member, second pin means extending between said end portions of said second grip member with opposite ends of said second pin means being removably connected to said end portions of said second grip member, at least one endless band of elastomeric materIal being looped around said first and second pin means for establishing a force between said first and second grip members when said endless band is stretched beyond a predetermined distance measured from said first pin means to said second pin means, a movable support member provided with a planar surface substantially larger than said first grip member, and means securing said end portions of said first grip member in abutment against said planar surface of said support member so that said second grip member will be free and unrestrained to move in any direction above said planar surface, said second member being attached to said planar surface only by said second means.
Claim 2
Dependent Claim
211 words
An exercising apparatus comprising first and second gripping means each provided with two parallel end portions to define first and second U-shaped grip members respectively, first pin means extending between said end portions of said first grip member with opposite ends of said first pin means being removably connected to said end portions of said first grip member, second pin means extending between said end portions of said second grip member with opposite ends of said second pin means being removably connected to said end portions of said second grip member, at least one endless band of elastomeric materIal being looped around said first and second pin means for establishing a force between said first and second grip members when said endless band is stretched beyond a predetermined distance measured from said first pin means to said second pin means, a movable support member provided with a planar surface substantially larger than said first grip member, and means securing said end portions of said first grip member in abutment against said planar surface of said support member so that said second grip member will be free and unrestrained to move in any direction above said planar surface, said second member being attached to said planar surface only by said second means.
Claim 3
Dependent Claim
20 words
An exercising apparatus as defined in claim 1, wherein said support member comprises a flat sheet of substantially rigid material.
Claim 4
Dependent Claim
44 words
An exercising apparatus as defined in claim 1, wherein a plurality of endless bands are provided each of which is disconnectable from said first and second pins means, whereby the force exerted can be regulated by selecting a desired number of said endless bands.
Claim 5
Dependent Claim
14 words
An exercising apparatus as defined in claim 1, wherein said elastomeric material is rubber.
Claim 6
Dependent Claim
72 words
An exercising apparatus as defined in claim 1, wherein said exercising apparatus is utilized as a hand wrestling exercising apparatus wherein said second grip member is gripped by a hand of a person while his elbow rests on said support member, further comprising soft cushioning means cooperating with said support member and adapted to be interposed between said support member and a person''s elbow to cushion the elbow from said support member.
Claim 7
Dependent Claim
39 words
An exercising apparatus as defined in claim 1, wherein said support member is adapted to be positioned on a relatively flat, horizontal surface during use, and further comprising clamp means for clamping said support means to said horizontal surface.
