Abstract

A device for exercising the extensor muscles of the arm comprises two elongated rigid arm members connected together by a pair of coil springs for pivotal movement about a transverse axis. The arm members include straps for mounting the device to a user'"'"''"'"'s arm with one arm member alongside the user'"'"''"'"'s upper arm and the other arm member alongside the user'"'"''"'"'s forearm. The pivot axis of the arm members is located so as to extend transversely through his elbow. The coil springs provide a preset resistance to the muscle action required to straighten the arms as the user moves his arm to and from an extended position.

Claims

1. An arm exercising device comprising:

a first elongated rigid arm member;

means on said first arm member for mounting of the first arm to a user'"'"''"'"'s upper arm between his elbow and shoulder;

a second elongated rigid arm member;

abutment means on said second arm engageable with the user'"'"''"'"'s forearm outward of the elbow;

said first and second members being operatively joined to one another for angular movement relative to one another about a pivot axis extending transversely between the members; and

biasing means connecting the first and second members for normally urging said first and second arm members in relatively opposed angular directions about the pivot axis to a closed or bent condition.

2. The device set out in claim 1 wherein the first arm member comprises:

two longitudinal side bars extending radially from inside ends adjacent said axis and spaced apart laterally a distance sufficient to allow reception of the user'"'"''"'"'s arm lengthwise between them;

a first U-shaped strap mounted transversely between the side bars adjacent the pivot axis; and

a second strap fixed between the side bars longitudinally spaced from the first strap and having an Inverted U-shape with respect to the first strap thereby defining a passage extending longitudinally along the first rigid arm member for receiving the user'"'"''"'"'s upper arm therein.

3. The device set forth in claim 2 wherein the second elongated rigid arm comprises:

two longitudinal side members extending radially outward from inside ends adjacent said pivot axis and laterally spaced apart a distance sufficient to allow the user'"'"''"'"'s arm to be positioned therebetween; and

a cross member connecting the remaining ends of the side members.

4. The device set forth in claim 2 wherein the second elongated rigid arm comprises:

two longitudinal side members extending radially outward from inside ends adjacent said pivot axis and laterally spaced apart a distance sufficient to allow the user'"'"''"'"'s arm to be positioned therebetween;

a cross member connecting the remaining ends of the side members; and

wherein said abutment means comprises a transverse flexible tube mounted to and extending transversely between the side members for free movement along the side members between the inside ends thereof and said cross member.

5. The device defined in claim 3 wherein the biasing means comprises a pair of coiled springs, each fixed between corresponding inside ends of the first and second rigid arm members.
