Abstract
There is provided a unique weight lifting spotting pin which provides an assist to the weight lifter to speed the development of his lifting ability. The inventive spotter pins mount to typical weight lifting power rack to provide a rest for a weight bar. A helical spring forms the weight bearing element of the spotter pin, flexing downwardly under the weight of the resting weight bar. As a lifter begins to lift the weight bar, the helical spring tends to return to its natural, unflexed position, thereby helping to snap the weight bar upwardly from the spotter pin. With an assist in initiating the lift, a weight lifter may more rapidly increase his lift weight, thereby speeding the training time required to achieve a desired weight lift.
Claims6
A spring assisted weight lifting spotter pin assembly adapted for use with a weight lifting power rack, said spotter pin assembly comprising:
- 1) a contiguous, substantially U-shaped spotter spin, said spotter pin having at least three rigid walls comprising:
- a lower horizontal arm having two adjoining vertical walls on either end,
- said two adjoining vertical walls each having a proximal end and a distal end;
- 2) spring means laterally extending along a horizontal plane parallel with said lower horizontal arm of said spotter pin,
- said spring means adapted and configured to provide horizontal tension forces, said horizontal tension forces providing an added assist resulting in vertical forces when a tangential force is applied thereupon by weights;
- and
- 3) a first and second spring coupling means for coupling spring means to both said adjoining vertical walls, both said first and second spring coupling means having a first and second end,
- and wherein the distal end of at least one of said adjoining vertical walls has mounting means for mounting to a weight lifting rack,
- wherein each of said two adjoining vertical walls extend at substantially right angles at their distal ends relative to said lower horizontal arm;
- wherein both said first ends of said spring coupling means has spring connector means for directly coupling each end of said spring means to each of said first and second spring coupling means,
- said proximal ends having a first fastening means for providing attachment to a spring means.
