Abstract
Abstract A physical exerciser including two handle pieces, a first tube having one end secured to one of the handle pieces and the other end fixedly received in a first bracket, and second and third tubes extending through bores provided in the first bracket and each having one of their ends connected to a second handle piece through a second bracket and opposite ends of the second and third tubes connected to a third bracket. Coiled springs may be disposed between the second and first brackets to oppose inward movements of the handle pieces. Rubber bands may be connected between the first bracket and the third bracket to resist inward movement of the handle pieces.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
190 words
An exercising device comprising a first handle piece; a first rigid strut member having one end secured to the first handle piece; first bracket means fixedly mounted at the other end of said first strut member; second and third rigid strut members extending slidably through bores provided in said first bracket means and positioned on opposite sides of the connection of said one end of said first strut member with said first bracket means; and said second and third strut members being slidably connected to the first rigid strut member between the first bracket means and the first handle piece; third bracket means fixedly receiving one end of each of the second and third strut members, second bracket means having a central bore to slidably receive said first strut member therein; said third bracket fixedly receiving the opposite end of each of the second and third rigid strut members; a second handle piece; and resilient means connected to and cooperating with said first bracket means to elastically oppose the displacement of said first bracket means relative to said third bracket means when opposite forces are exerted on said handle pieces.
Claim 2
Dependent Claim
190 words
An exercising device comprising a first handle piece; a first rigid strut member having one end secured to the first handle piece; first bracket means fixedly mounted at the other end of said first strut member; second and third rigid strut members extending slidably through bores provided in said first bracket means and positioned on opposite sides of the connection of said one end of said first strut member with said first bracket means; and said second and third strut members being slidably connected to the first rigid strut member between the first bracket means and the first handle piece; third bracket means fixedly receiving one end of each of the second and third strut members, second bracket means having a central bore to slidably receive said first strut member therein; said third bracket fixedly receiving the opposite end of each of the second and third rigid strut members; a second handle piece; and resilient means connected to and cooperating with said first bracket means to elastically oppose the displacement of said first bracket means relative to said third bracket means when opposite forces are exerted on said handle pieces.
Claim 3
Dependent Claim
60 words
An exercising device as defied in claim 1, wherein said first, second and third strut members are tubular shaped, wherein said second handle piece is fixedly mounted to the second bracket means, the opposite ends of said second and third strut members being fixed to said third bracket means, and an endless rope extending through each of the handle pieces.
Claim 4
Dependent Claim
48 words
An exercising device as defined in claim 2, wherein said resilient means consist of a pair of compression springs, each spring being mounted about each of said second and third strut members between said first and second bracket means, the exercisinG being obtained by compressing said compression springs.
Claim 5
Dependent Claim
52 words
An exercising device as defined in claim 2, wherein said resilient means consist of a pair of strips of rubber material, each strip having one end connected to said first bracket means and the other end to said third bracket means, the exercising being obtained by stretching said strips of rubber material.
