Abstract

A stretchable exercising device is integrally molded from elastic material and has two separate strap sections each with a handle loop. The strap sections being connected to only one other strap section at a generally central, integral joinder which forms a single continuous uninterrupted unitary connection. The other strap section has a greater resistance to stretching than any of the remaining two, due to an increased cross-sectional area. The loop of the other strap section is large enough to receive two feet in a side-by-side disposition. The remaining two strap sections may also be of mutually different resistance to the stretching force.

Claims

1. An exerciser comprising, in combination:

(a) a first elongated elastic strap section and a second elongated elastic strap section;

(b) said first elongated elastic strap section and said second elongated elastic strap section being of the same length and being molded integrally with a centrally located joinder section such that said first elongated strap section and said second elongated strap section are normally disposed at an acute angle relative to each other and forms a continuous uninterrupted member;

(c) a first handle loop means and a second handle loop means integral with the free ends of said first and second elongated strap sections, respectively, said first and second handle loop means being of identical shape and size relative to each other;

(d) only one unitary, third elastic strap section protruding from and molded with said joinder section and being integral with same, said third strap section being disposed such that it normally forms the leg of one generally uninterrupted unitary Y-shaped configuration whose arms are defined by said first and second elongated strap section, the cross-sectional area of said third strap section being generally equal to the sum of cross-sectional area of said first elongated strap section and of cross-sectional area of said second elongated strap section;

(e) a third loop means integral with the free end of said third strap section remote from said joinder section, said third loop means being about twice the size of any of said first and second handle loop means, the size of the third loop means being in the range sufficient to accommodate within said third loop means at least two human feet of an average size in a side-by-side disposition.

2. An exerciser as claimed in claim 1, wherein the length of the first elongated elastic strap section is generally equal to the length of the second elongated elastic strap section.

3. An exerciser as claimed in claim 2, wherein the length of the third elongated elastic strap section is generally equal to the length of the second elongated elastic strap section.

4. An exerciser comprising, in combination:

(a) a first elongated elastic strap section and a second elongated elastic strap section;

(b) said first elongated strap section and said second elongated elastic strap section being of the same length and being molded integrally with a centrally located joinder section such that said first elongated elastic strap section and said second elongated elastic strap section are normally disposed at an acute angle relative to each other and forming a continuous uninterrupted member;

(c) a first handle loop means and a second handle loop means integral with the free ends of said first and second elongated elastic strap sections, respectively, said first and second hand loop means being of identical shape and size relative to each other,

(d) only one unitary, third elastic strap section protruding from and molded with said joinder section and being integral with same, said third strap section being disposed such that it normally forms the leg of one generally uninterrupted unitary Y-shaped configuration whose arms are defined by said first and second elongated strap-section;

(e) a third loop means integral with the free end of said third strap section remote from said joinder section, said third loop means being about twice the size of any of said first and second handle loop means, the size of the third loop means being in the range sufficient to accommodate within said third loop means at least two human feet of an average size in a side-by-side disposition;

(f) the size of the cross-sectional area of said first elongated elastic strap section being different from that of said second elongated elastic strap section, whereby each of said first, second and third strap sections has a different degree of resistance to a stretching force;

(g) the size of the cross-sectional area of said third elastic strap section being generally equal to the sum of the cross-sectional area of said first elongated elastic strap section and of the cross-sectional area of said second elongated elastic strap section.

5. An exerciser as claimed in claim 4, wherein the length of the first elongated elastic strap section is generally equal to the length of the second elongated elastic strap section.

6. An exerciser as claimed in claim 5, wherein the length of the third elongated elastic strap section is generally equal to the length of the second elongated elastic strap section.
