Free motion swing arm
View Patent ↗A free-motion swing arm includes a rack mount; a swivel joint; a hollow tubular arm; and a U bracket with a handle and a weight bearing post extending from opposite surfaces. The rack mount has a handle and mounts on an exercise rack. The swivel joint includes a bearing and a mounting plate, mounts on the rack mount, and rotates about a vertical axis. The arm is mounted to the mounting plate, rotates about a horizontal axis, and is reversibly lockable in multiple positions. The U bracket is mounted to the arm. The swing arm allows movement 180 degrees on both a vertical axis and horizontal axis and in between at the same time for free movement.
1. A free-motion swing arm mountable on an exercise rack, comprising:
a rack mount having a first surface, a second surface with sidewalls extending from the second surface and orthogonal thereto, the sidewalls having apertures formed therethrough, and a first handle on the first surface;
at least one locking pin engageable through the apertures, the locking pin being configured to secure the rack mount to the exercise rack when the locking pin is engaged through the apertures;
a swivel joint rotatable about a vertical axis mounted on the second surface of the rack mount, the swivel joint comprising a bearing and a mounting plate coupled to the bearing;
a hollow tubular arm hingedly mounted to the mounting plate and rotatable about a horizontal axis; and
a U bracket mounted to the hollow tubular arm, having a second handle extending from a first surface of the U bracket and a weight bearing post extending from a second surface of the U bracket;
wherein the hollow tubular arm is reversibly lockable in a plurality of positions; and
wherein the rack mount, the swivel joint, the hollow tubular arm, and the U bracket are configured to be slidably moveable along the exercise rack when the at least one locking pin is not engaged through the apertures, but the rack mount stays locked in place on the exercise rack when the at least one locking pin is engaged through the apertures.
2. The free-motion swing arm of claim 1 , wherein the hollow tubular arm, and the U bracket are formed with attachment apertures operative to accommodate additional locking pins.
3. The free-motion swing arm of claim 1 , wherein the mounting plate has a substantially truncated wedge shape with a plurality of holes on said substantially truncated wedge shape that allow the hollow tubular arm to be lockable in a second position relative to the horizontal axis.
4. The free-motion swing arm of claim 1 , wherein the second handle is substantially U-shaped with a crossbar.
5. The free-motion swing arm of claim 1 , wherein the swivel joint has holes evenly spaced in a half ring; and at least one additional locking pin engageable through the holes, wherein the at least one additional locking pin when engaged through at least two of the holes is configured to lock the swivel joint in place.
6. The free-motion swing arm of claim 1 , wherein the first surface is coupled to the sidewalls with bolts.
