Abstract

A weighted exercise bar A is illustrated as including a pair of sections (10) and (12) joined together at a moment resisting joint (B) by means of a cam lock slot and pin (32), (34). Weights (C) provide uniform extensions at the ends of the bar.

Claims

1. An exercise bar device for use in twisting exercises about the exerciser'"'"'s waist comprising:

an elongated bar including a plurality of elongated sections joined by a releaseable joint between adjoining ends of adjacent sections forming a bar of a predetermined length defined by the outermost remote ends of said sections joined together;

said elongated bar being generally straight and uniform in its cross-section along its entire length;

a generally solid weighted member carried at each of said ends extending longitudinally therefrom within the periphery of said bar;

each said weight member having a cross-section corresponding to the cross-section of said bar defining weighted uniform extensions of about two and one-half pounds thereof at said ends;

said elongated bar having a sufficient length so that said weighted extensions extend past the hands of an exerciser when gripping the bar in an exercise position with the arms spread and the bar supported on the shoulders for twist exercising;

a quick release connection joining said sections together at said joint enabling said device to be broken down into sections for storage and transportation; and

said length of said elongated bar having a ratio to the total length of said weight members of approximately five to one so that an exercise bar is provided having effective accelerating torque for exercise yet may be grasped by outreached hands without reaching the weights and whose total length is not unweildly facilitating use in an interior room space and the like.

2. An exercise bar device for use in twisting exercises about the exerciser'"'"'s waist comprising:

an elongated bar including two elongated sections having a joint approximately midway of said bar forming a bar of a predetermined length defined by two remote ends of said sections joined together;

said elongated bar being generally straight and uniform in its cross-section along its entire length;

a weighted member of about two and one-half pounds carried at each of said ends extending longitudinally therefrom within the periphery of said bar;

said weighted member having a cross-section corresponding to the cross-section of said bar defining weighted uniform extensions thereof at said ends;

said elongated bar having a sufficient length so that said weighted extensions extend past the hands of an exerciser when gripping the bar in an exercise position with the arms spread and the bar supported on the shoulders for twist exercising;

a quick release connection joining said sections together at said joint enabling said device to be broken down into sections for storage and transportation;

a tubular hollow sleeve included in said quick release connection fixed to a first adjoining end of a first of said sections, said sleeve being open at an opposing end for receiving a second adjoining end of a second of said sections, said sleeve effectively resisting flexing of said first and second sections relative to each other during twisting exercises;

said quick release connection including a cam slot formed in said sleeve affixed to said first adjoining end, said cam slot including a circumferential slot and longitudinally formed lock slot;

a lock pin carried by said second adjoining end of said second section;

a joint space formed between said first adjoining end of said first bar section and said second adjoining end of said second bar section when received in said tubular sleeve affixed to said first section; and

biasing means carried in said joint space between said first and second adjoining ends of said first and second sections urging said lock pin into a locking position in said lock slot, said biasing means urging said second adjoining end in a direction opposite to said first adjoining end within said tubular sleeve; and

a generally rigid joint which is generally free of play provided for said adjoining ends of said first and second sections by said quick release connection at said joint so that said sections do not flex relative to each other during twisting exercises yet are quickly releasable for breakdown.
