Elastic device
An arm and chest exerciser includes elastic cuffs into which a user places the upper arms. An elastic chest band connects the cuffs. Moving the user's arms backwardly stretches the chest band and exercises muscles of the arms, chest and shoulder. A gripping handle connects to the chest band adjacent to a midpoint allowing the user or spotter to pull down on the chest band and appropriately position it on the user's chest.
1. An arm and chest elastic device comprising:
first and second arm cuffs configured to encircle an upper portion of a user's left and right arms;
a chest band comprising a central elastic member of generally rectangular shape with a long dimension and a short dimension, the first and second arm cuffs being attached to opposite ends of the central elastic member, the central elastic member being configured to extend across a chest of the user; and
a gripping handle of generally rectangular shape attached to the central elastic member adjacent to a midpoint thereof and extending perpendicularly away from the long dimension of the central elastic member;
the gripping handle being configured to be pulled by a third party during stretching of the chest band and thereby adjust the position of the chest band on the chest of the user.
2. The arm and chest elastic device of claim 1 wherein the gripping handle includes an elastic section secured to the chest band and an inelastic section extending away from the chest band.
3. The arm and chest elastic device of claim 2 wherein the central elastic member comprises a rubber sheet having a width, a length and a thickness wherein the width and length are at least ten times the thickness.
4. The arm and chest elastic device of claim 3 further comprising a fabric sleeve encasing the central elastic member.
5. The arm and chest elastic device of claim 1 wherein the gripping handle comprises an elastic section fixed to the central elastic member and an inelastic member fixed solely to the elastic section thereby connecting the inelastic member to the chest band member through the elastic section.
6. The arm and chest elastic device of claim 5 wherein the elastic section of the gripping handle comprises a tube and the inelastic member is located inside the tube.
7. The arm and chest elastic device of claim 5 wherein the elastic section of the gripping handle comprises a strap and the inelastic member is fixed to the strap rendering part of the elastic section of the gripping handle inelastic.
8. The arm and chest elastic device of claim 1 wherein the central elastic member is expansible in a first direction between the first and second arm cuffs and expansible in a second direction perpendicular to the first direction, expansibility of the central elastic member in the first direction being substantially equal to expansibility of the central elastic member in the second direction.
9. The arm and chest elastic device of claim 1 wherein the central elastic member comprises a rubber sheet.
