BACKGROUND OF INVENTION

[0004] 1. Field of Invention

[0005] In power lifting, athletes lift tremendous amounts of weight, often in excess of 1,000 pounds. When an athlete is engaged in this rigorous activity they place a tremendous amount of stress on their joints, and too much weight, or excess stress, can put the athlete at risk. To minimize this risk many athletes wrap pre-tensioned knee wraps around their knees for added support. The problem with pre tensioned knee wraps is that the tighter they are wound the tighter they can be wrapped around the knees. It is difficult to consistently wrap and re-wrap knee wraps with the needed tension. Athletes lifting over 1,000 pounds need every bit of energy they can muster, and the painful process of manually rolling wraps by hand requires the athlete to expend valuable energy, and results in fatigue and tremendous pain to the athletes forearms.

[0006] 2. Description of Related Art

[0007] Another invention has attempted to solve this problem, but their inventions do not offer the same solution or functionality that the Wrap Adaptor solves. US Provisional Application 20030218090, Filing Date Feb. 21, 2003, Inventor, David A. Stith titled "Power Wrap Roller" uses a larger separate stand alone device that uses mutiple rollers to wrap the knee wraps. This device is bulkier, larger, and does not offer the portability that is offered by the Wrap Adaptor.

SUMMARY OF INVENTION

[0008] The present invention eliminates the fatigue and strength sapping effort that power-lifters expend in manually rolling knee wraps, by providing an apparatus and method that requires very little effort. The present invention allows the power lifter to roll knee wraps with optimal tension without expending a lot of energy, or requiring the use of bulky equipment.

DESCRIPTION OF FIGURES

[0038] FIG. 1 is a horizontal view of the Wrap Adaptor as it would appear prior to being inserted into a drill. The Wrap Adaptors 10 front end has a 1/4'' by 3'' deep center bored hole 14 in main shaft, inside Front End of main shaft is grooved insert for 1/4'' Selector Pin 36 to be inserted, screwed into place, to operate as pivoting handle during wrap winding process, or stored while Wrap Adaptor is inactive (See FIG. 3, 3A, 3B). Two holes drilled into the Wrap Adaptors main shaft 10, one at 16 and another at 18. Hole 16 is used to insert and weld L Shaped 1/8'' by 3'' Retainer Bar 12 into hole 16; Hole 18 is used to insert 1/4'' Selector pin 36 into Hole 18 (See FIG. 4B) to form a T-Bar handle used in removal of wrap from Wrap Adaptor (See FIG. 4B). The drill insertion point 20 is then locked into place in drill (See FIG. 1A)

[0039] FIGS. 2 and 2A is Top and Side view of Foot Plate 26 used to remove knee wrap 34 from Wrap Adaptor Shaft (See FIG. 4B). The Foot Plate 26 is a steel rectangular shaped design with a 5/8'' wide by 11/4'' deep rounded opening at the top 28. Each side of the rectangular shaped Foot Plate 26 are 6'' in length by 2'' in width with Top of surface measuring 4'' in length by 2'' in width. The Bottom of the design is left open with two 4'' by 2'' platforms extending from bottom of each side wall 30L and 30R of the Foot Plate 26 that are used to balance Foot Plate 26 during removal of knee wrap 34 (See FIG. 4B)

[0040] FIGS. 3 and 3A are close-up side views of Selector Pin 36 and Selector Pin insertion 42, 44, 46, 48, into Wrap Adaptor 24, the Selector Pin 36 with threaded end 42 is used to screw Selector Pin 36 into front center bored hole in Wrap Adaptor Shaft 14 by inserting the Selector Pin insertion point 44 into the front center bored hole of Wrap Adaptor Shaft 14. The Selector Pin is inserted into front center bored hole 14 and screwed into place inside Wrap Adaptor shaft 46, with the Selector Pin Connector 48 forming a bond with the front end of Wrap Adaptor Shaft 10, 14.

[0041] FIG. 3B is close up view of Selector Pin 36 as it appears when attached to and screwed into Wrap Adaptor Front center bored hole 14; 42, 44, 46, 48, and 24. That is used as pivotal handle during wrap rolling process, or as storage location for Selector Pin 36

[0042] FIGS. 4 and 4A are views of Knee Wrap 34 being inserted under Retainer Bar 12 that is welded onto Wrap Adaptor Shaft 10. The Wrap Adaptor Insertion Point is then inserted into drill chuck 20 (See FIG. 4A). The drill 22 is then used to wind Wrap Adaptor around Wrap Adaptor Shaft, until tightly wound, at which point a rubber-band is placed around knee wrap 34 (See FIGS. 4A and 4B)

[0043] FIG. 4B is view of Wrap Adaptor shaft with rolled rubber band wrap attached, that slides under Foot Plate 26 opening 28 at the top with knee wrap 34 inserted under opening 28. The Wrap Adaptor Shaft is then pulled upward against top of Foot Plate 26 using the Selector Pin 36 that operates as a T-Handle used to free wound rubber-banded wrap from Wrap Adaptor.

OPERATION OF FIGURES

[0044] As shown in FIG. 1 the Wrap Adaptor 24 is used to insert wrap 34 under welded retainer bar 12 with the Wrap Adaptor drill insertion point 20 inserted into drill chuck and tightened (See FIGS. 4 and 4A). The drill 22 then spins Wrap Adaptor shaft 10 with wrap 34 being tightly wound as shaft spins until wrap is completely wound (See FIG. 4B). Once wrap is wound, a rubber-band is placed around wrap, the power-lifter stands on foot platform 30L and foot platform 30R with the Wrap Adaptor in a vertical position being inserted into Top of Foot Plate 26 opening 28; the Wrap Adaptor 24 with wrap 34 is then slid into the Foot Plate opening 28 with wrap 34 resting under Foot Plate opening 28 (See FIG. 4B). The Wrap Adaptor Shaft 10 is then pulled upward using the Selector Pin 36 that has been inserted into Selector Pin insertion point 18 in base of Wrap Adaptor Shaft 10 (See FIG. 4B). The Wrap Adaptor is then pulled upward using T-Bar handle formed by inserting Selector Pin 36 into Wrap Adaptor Selector insertion point 18 and pulling upward against top of Foot Plate 26 opening 28. The wrap 34 is then freed from Wrap Adaptor 24, and the rubber band rolled wrap is then ready to be put away until used, with process being repeated as many times as necessary.

DETAILED DESCRIPTION

[0045] The Wrap Adaptor is inserted into a drill with the Wrap inserted under a Retainer Bar, while the Operator steps on the other end of the wrap with their foot, supplying the required tension. The Wrap Adaptor is then powered, which will cause the wrap to be wound tightly around the Wrap Adaptor. Once rolled, a rubber-band is placed around the Wrap, the operator places the Wrap Adaptor with rolled rubber band wrap into a slot at the top of the Foot Plate with operator inserting selector pin into hole at base of Wrap Adaptor Shaft. Once selector pin is inserted into Wrap Adaptor shaft, the operator pulls the Wrap Adaptor up against Foot Plate using T-Bar Handle formed by Selector Pin insertion into hole at base of Wrap Adaptor shaft, Using T-Bar handle Wrap Adaptor is pulled upward against top of Foot Plate, freeing the knee wrap from Wrap Adaptor shaft
