Abstract

A tension exercise device of the chest pull type includes a flexible band that has flexible handles on each end thereof. The handles have grooves defined therein and a hand-hole defined therethrough. The hand-holes are oblong and somewhat egg shaped with a major axis extending along the length dimension of the band. The band is formed of lightweight material, such as latex, and the handles are also formed of elastomeric material.

Claims

1. A resistance-type exercising device comprising:

a monolithic, one-piece body having

(1) a flexible resistance band having first and second ends, first and second sides with a width dimension defined between said sides and a length dimension extending between said ends,

(2) a handle on each end of said band, each of said handles including

(a) a plurality of grooves defined therein to extend along said band length dimension,

(b) an oblong hand-accommodating hole defined through said handle and having a major axis extending lengthwise of said band, and

(c) each handle being formed of flexible elastomeric material which co-operates with said grooves so that each handle is flexible to fold, in use, about the band longitudinal centerline.

2. The device defined in claim 1 wherein said each handle has a front surface and a rear surface and said grooves are defined in both said front and rear surfaces.

3. The device defined in claim 2 wherein said opening is triangular in shape.

4. A tension-type exercising device comprising:

(A) a flexible resistance band having a front surface a rear surface, first and second sides and first and second ends, a width dimension defined between said first and second sides, a length dimension defined between said first and second ends, and a thickness dimension defined between said front surface and said rear surface, said ends being sinusoidal in shape to have a valley between two peaks with each of said peaks being located adjacent to one of said band sides; and

(B) two handle units, each handle unit including

(1) a front plate-like element affixed to said band adjacent to each end of said band on said band front surface and a rear plate-like element affixed to said band adjacent to each end of said band adjacent to said band rear surface, each plate-like element having an oblong hole defined therethrough which has a major axis co-linear with said band longitudinal axis, and which is congruent with an oblong hole defined a plate-like element associated therewith to define a single oblong hole in each handle,

(2) a multiplicity of grooves defined in each plate-like element to extend lengthwise of said band when said plate-like elements are affixed thereto, and

(3) each plate-like element being formed of elastomeric material and being flexible about the band longitudinal axis to bend into a tubular configuration about such band longitudinal axis in use.

5. The device defined in claim 4 wherein said band is formed of latex.

6. The device defined in claim 5 wherein said thickness dimension is about one-sixteenth of an inch.

7. The device defined in claim 6 further including a cover on each handle unit.

8. The device defined in claim 7 wherein said plate-like elements are all formed of elastomeric material.

9. The device defined in claim 8 wherein each handle unit is polygonal in shape and has at least six sides.

10. The device defined in claim 9 wherein each of two of said handle six sides intersects adjacent sides at an oblique angle.

11. The device defined in claim 10 wherein two other handle unit sides of said six sides are co-linear with said resistance band first and second sides and another side of said handle unit six sides is located adjacent to one end of said resistance band and is parallel to a remaining side of said handle unit six sides.

12. The device defined in claim 11 wherein said oblong opening in each plate-like element is egg-shaped with a large end located adjacent to said remaining side, and a small end located adjacent to said resistance band one end.

13. The device defined in claim 12 wherein said egg-shaped opening large end is formed by a first curved edge, and said egg-shaped opening small end is formed by an intersection of two curved edges which also intersect said first curved edge.

14. The device defined in claim 13 wherein said flexible resistance band has a longitudinal centerline extending along said length dimension intermediate to said first and second sides and further wherein each of said handle unit plate-like elements has a centerline which is co-linear with said flexible resistance band longitudinal centerline, and said small end in each plate-like element openign is located on said plate-like element longitudinal centerline.

15. The device defined in claim 14 wherein each plate-like element longitudinal centerline bisects the first curved edge of the opening defined in said each plate-like element.
