Abstract
Abstract At least four elongated straps of a highly elastic resilient material, such as stiffened rubber, each having a thickened handle portion at the outer end, extend outwardly in divergent directions from a central junction where the inner ends are integrally joined together and forming one uninterrupted structure. The handles are formed to permit one or more to be held with the hand or foot during performance of various resistive exercises that involve stretching the elastic straps. Preferably the strap, handle and junction portions are integrally molded. The amount of muscular force exerted can be varied in different exercises for maximum effect by selecting the number of straps to be stretched and by adjusting the transverse tension applied to one or more straps held stationary while others are stretched longitudinally.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
108 words
A unitary resistive exercise device comprising: a plurality of at least three straps consisting of a highly elastic resilient material; handle means of said material affixed to the outer end of each said straps and adapted to be held with the hand or foot of an exerciser; and a central junction portion integrally joining and forming one uninterrupted structure with the inner ends of each of said straps, which radiate therefrom whereby one or more of said handle means are held by selected ones of the exerciser's hands or feet or by an external object to provide a variable resistive force in stretching different combinations of said straps.
Claim 2
Dependent Claim
108 words
A unitary resistive exercise device comprising: a plurality of at least three straps consisting of a highly elastic resilient material; handle means of said material affixed to the outer end of each said straps and adapted to be held with the hand or foot of an exerciser; and a central junction portion integrally joining and forming one uninterrupted structure with the inner ends of each of said straps, which radiate therefrom whereby one or more of said handle means are held by selected ones of the exerciser's hands or feet or by an external object to provide a variable resistive force in stretching different combinations of said straps.
Claim 3
Dependent Claim
24 words
The resistive exercise device of claim 1 wherein: said straps, handle means and junction portion are all integrally molded from a stiffened rubber mixture.
Claim 4
Dependent Claim
55 words
The resistive exercise device of claim 1 wherein: said central junction portion consists of a flat oblong section of said elastic resilient material formed integrally with said straps extending outward in diverging directions from the corner areas thereof, whereby the distance between different straps held in an unstretched condition may be varied for different exercises.
Claim 5
Dependent Claim
57 words
The resistive exercise device of claim 1 wherein: each of said handle means consists of a bifurcated outer end section terminating each of said straps to join opposite ends of a thicker handle portion, said bifurcated outer end section and said thicker handle portion being formed integrally with said straps and consisting of said elastic resilient material.
Claim 6
Dependent Claim
42 words
The resistive exercise device of claim 1 wherein: each of said straps is of substantially the same length and thickness; whereby different pairs of said handle means may be held together to vary the resistive force required to stretch a predetermined distance.
Claim 7
Dependent Claim
85 words
A resistive exercise device comprising: a plurality of at least four resilient handle means adapted to be held by a hand or foot of the exerciser; a plurality of elastic strap means joining said handles, each of said straps being integrally joined together and forming one uninterrupted structure, said strap being joined approximately midway between said handles, whereby different ones of said handles when aligned in an unstretched condition may be held alone or together to vary the resistive force produced in stretching various straps.
Claim 8
Dependent Claim
85 words
A resistive exercise device comprising: a plurality of at least four resilient handle means adapted to be held by a hand or foot of the exerciser; a plurality of elastic strap means joining said handles, each of said straps being integrally joined together and forming one uninterrupted structure, said strap being joined approximately midway between said handles, whereby different ones of said handles when aligned in an unstretched condition may be held alone or together to vary the resistive force produced in stretching various straps.
Claim 9
Dependent Claim
39 words
The resistive exercise device of claim 6 wherein: said straps are integrally molded together from a highly elastic resilient material to form a unitary central junction portion of oblong proportions from which said straps extend outwardly in divergent directions.
Claim 10
Dependent Claim
49 words
The resistive exercise device of claim 6 wherein: said handle means are molded integrally with said straps to consist of a highly elastic resilient material to provide a thicker rounded cross section with dimensions that permit a plurality of said handles to be securely grasped together in one hand.
Claim 11
Dependent Claim
49 words
The resistive exercise device of claim 6 wherein: each of said handle means consist of a thicker transverse handle portion joined to said strap on opposite sides by a bifurcated end section to define an opening permitting insertion of a hand, foot or external object to hold said handle.
