Abstract

A folding portable exercise apparatus having a contoured chest bar and a contoured lap bar. Two pairs of rods connect the bars. Each pair of rods is joined by a coil spring. An adjustable belt may be fastened around underneath the user. The device may be used to exercise the upper abdominal muscles, the triceps, the biceps, the pectoral muscles, the latissimus muscles, the back and lower abdominal muscles and the leg muscles such as calves, quadriceps, hamstring and gluteal muscles. The device may be disassembled and folded into a compact arrangement for storage and travel by detaching the coil springs from one pair of rods. This allows the device to be separated into components. The four rods may lie in the cavity along the major length of the respective chest bar and lap bars. The belt, springs and thumbscrews may then also lie together within the cavities and when closed produce a compact package the length and width of the chest bar and lap bar.

A folding portable exercise apparatus, comprising:

a first bar having a first longitudinal axis;
a second bar having a second longitudinal axis;
a first pair of rods each having a proximal end and a distal end, means for pivotally connecting said proximal ends of said first pair of rods to said first bar allowing movement of said first pair of rods between a folded position wherein said rods lie substantially along said first longitudinal axis and an unfolded position wherein said rods lie substantially at right angles to said second longitudinal axis;
means for locking said first pair rods in said unfolded position;
a second pair of rods each having a proximal end and a distal end, means for pivotally connecting said proximal ends of said second pair of rods to said second bar allowing movement of said second pair of rods between a folded position wherein said rods lie substantially along said second longitudinal axis and an unfolded position wherein said rods lie substantially at right angles to said second longitudinal axis;
means for locking said second pair of rods in said unfolded position;
a pair of coil springs, each having a helically wound portion and a first and second projecting arm, said projecting arms diverging from each other at a given acute angle;
means for removably connecting each of said first projecting arms to a respective one of said distal ends of said rods attached to said first bar;
and means for removably connecting each said second projecting arms to a respective one of said distal ends of said arms attached to said second bar, and;
wherein said means for locking said first and second pairs of rods in said unfolded position comprises an indentation in each of said first and second bars at each of said proximal ends of said rods and traverse to said longitudinal axes of said bars, a pin affixed in each of said indentations said pin passing through an opening in said proximal ends of said rods allowing pivotal motion of said rods with respect to said pins and further allowing said distal ends to lie within said indentations in said unfolded positions and to lie outside of said indentations in said. folded position.
