Abstract

A chest peak contractor preferably includes a platform, a pair of stanchions, a pair of vertically adjustable telescoping poles and a pair of armature hand assemblies. The pair of stanchions extend upward from opposing sides of the platform. Each stanchion is sized to receive one of the vertically adjustable telescoping poles. A top of each telescoping pole is terminated with a pivoting joint. Each armature device handle assembly is mounted to a top of the respective telescoping pole. Each armature handle assembly preferably includes a handle, a proximal axle support tube, an armature crossbeam, a distal hanger, a pair of backstop rails, a ring bolt backstop, an axle, and a weight holder. The handle is rotatably retained in the pivoting joint. An end of the handle is secured to the proximal axle support tube.

Claims (41)

1. A chest peak contractor comprising:

a support member; and

at least one armature handle device including a rotation member, a first hanger, a second hanger, an armature crossbeam, at least one axle and a weight holder, said rotation member is rotationally engaged with said support member, one end of said rotation member extends from said first hanger, a first end of said armature crossbeam is attached to said first hanger, a second end of said armature crossbeam is attached to said second hanger, a first end of said at least one axle is retained in said first hanger, a second end of said at least one axle is retained in said second hanger, said weight holder is retained on said at least one axle.

2. The chest peak contractor of claim 1 wherein:

said support member includes a platform and at least one telescoping pole, said at least one telescoping pole extends upward from said platform, said rotation member is rotationally engaged with a top of said at least one telescoping pole, respectively.

3. The chest peak contractor of claim 2 wherein:

the top of said at least one telescoping pole is terminated with a tee fitting, said rotation member is rotatably retained in said tee fitting, respectively.

4. The chest peak contractor of claim 1 wherein:

a handle extends from an opposing end of said rotation member.

5. The chest peak contractor of claim 1 wherein:

said first hanger includes a proximal outer tube and a proximal axle support tube, said proximal axle support tube is slidably received by said proximal outer tube, said first end of said armature crossbeam is attached to said proximal outer tube, said at least one axle is retained in said proximal axle support tube.

6. The chest peak contractor of claim 1 wherein:

said weight holder includes an outer tube, an inner tube and a weight projection, said outer tube is pivotally retained on said at least one axle, said outer tube is sized to receive said inner tube, said weight projection extends from a bottom of said inner tube.

7. The chest peak contractor of claim 1 wherein:

said at least one armature handle device is prevented from rotation by at least one object attached to said support member.

8. A chest peak contractor comprising:

a support member; and

an armature handle device including a rotation member, a first hanger, a second hanger, an armature crossbeam, at least one axle, a weight holder and two backstop rails, said rotation member is rotationally engaged with said support member, one end of said rotation member extends from said first hanger, a first end of said armature crossbeam is attached to said first hanger, a second end of said armature crossbeam is attached to said second hanger, a first end of said at least one axle is retained in said first hanger, a second end of said at least one axle is retained in said second hanger, said weight holder is retained on said at least one axle, said two backstop rails are retained in said armature crossbeam, a ring bolt backstop is slidaby retained on said two backstop rails, wherein said ring bolt backstop prevents said weight holder from rotating.

9. The chest peak contractor of claim 8 wherein:

said support member includes a platform and at least one telescoping pole, said at least one telescoping pole extends upward from said platform, said rotation member is rotationally engaged with a top of one of said at least one telescoping pole.

10. The chest peak contractor of claim 9 wherein:
