Abstract
Abstract An exercise device comprised of a plurality of sections which cooperate to form an elongated shaft of variable length. The ends of the elongated shaft include hand grips which are perpendicular to the elongated shaft. A separate rotatable gripping shaft is mounted to extend internally of the generally D-shaped frame member and oriented so as to be perpendicular to the length of the elongated shaft. Pin members that are T-shaped are used to be inserted into aligned holes in a mid section and end section of the elongated shaft to fixedly hold the sections together. A spring is connected to the top cross portion of the T-shaped member and the opposite end of the spring is connected to the base part of the T-shaped member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
338 words
An exercising device which comprises a plurality of elongated sections which are interconnected to one another to form an elongated shaft of variable length, said sections including a hollow mid section and two end sections, said hollow mid section having a series of aligned holes extending through the distal ends thereof, and said end sections having a series of aligned holes extending therethrough, said end sections having cross-sectional dimensions less than the cross sectional dimension of said mid section so as to be sideably positionable within a respective distal end of said mid section to vary the length of said elongated shaft; pin members for interengaging the aligned holes in said end sections with respective aligned holes in said mid section so as to maintain the length of said elongated shaft at a fixed desired length, said pin members being T-shaped so as to have a top cross part and a base part, with the base part of each T-shaped pin member having a greater length than the diameter of said mid section such that when the base part of each T-shaped pin member is fitted through the aligned holes of said mid section and said end sections, said base part of each T-shaped pin member will extend outwardly beyond said sections, each said pin member including a spring having one end attached to a top cross part of the respective T-shaped pin member and a second end connectable to the portion of the base part of the respective T-shaped pin member which extends beyond said sections when the respective T-shaped pin member is fitted through the aligned holes of said mid section and the respective end section; and gripping means fixedly connected to the respective ends of said end sections which are remote from said mid section, each said gripping means comprising a generally D-shaped frame member and a separate rotatable gripping shaft mounted to extend internally of said generally D-shaped frame member and oriented so as to be perpendicular to the length of said elongated shaft.

An exercising device which comprises a plurality of elongated sections which are interconnected to one another to form an elongated shaft of variable length, said sections including a hollow mid section and two end sections, said hollow mid section having a series of aligned holes extending through the distal ends thereof, and said end sections having a series of aligned holes extending therethrough, said end sections having cross-sectional dimensions less than the cross sectional dimension of said mid section so as to be sideably positionable within a respective distal end of said mid section to vary the length of said elongated shaft; pin members for interengaging the aligned holes in said end sections with respective aligned holes in said mid section so as to maintain the length of said elongated shaft at a fixed desired length, said pin members being T-shaped so as to have a top cross part and a base part, with the base part of each T-shaped pin member having a greater length than the diameter of said mid section such that when the base part of each T-shaped pin member is fitted through the aligned holes of said mid section and said end sections, said base part of each T-shaped pin member will extend outwardly beyond said sections, each said pin member including a spring having one end attached to a top cross part of the respective T-shaped pin member and a second end connectable to the portion of the base part of the respective T-shaped pin member which extends beyond said sections when the respective T-shaped pin member is fitted through the aligned holes of said mid section and the respective end section; and gripping means fixedly connected to the respective ends of said end sections which are remote from said mid section, each said gripping means comprising a generally D-shaped frame member and a separate rotatable gripping shaft mounted to extend internally of said generally D-shaped frame member and oriented so as to be perpendicular to the length of said elongated shaft.
Claim 3
Dependent Claim
29 words
The exercising device of claim 1 wherein said mid section includes a resilient material wrapped therearound for the prevention of skin abrasion when the exercising device is in use.
Claim 4
Dependent Claim
21 words
The exercising device of claim 1 wherein each said gripping shaft of each gripping means is sheathed with an absorbant material.
Claim 5
Dependent Claim
22 words
The exercising device of claim 1 wherein the second end of each spring connected to each T-shaped pin member is hook shaped.
