## Title
Reaction training belt with variable release resistance

## Abstract

A cost effective training belt that offers the ability to vary the release resistance and that allows the release resistance to remain relatively constant throughout the life of the belt. In one disclosed embodiment, the reaction belt has a first and second belt detachably secured together with a detaching structure that can connect the first and second belts together in at least two different ways. Each of the connecting ways offers a different release resistance; thereby a user can select the desired release resistance by selecting which way to connect the two belts together.

## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority to U.S. provisional patent application Ser. No. 60/951,190, filed on Jul. 20, 2007.


FIELD OF THE INVENTION
The present invention relates to a reaction belt, which is also commonly known as a shadow belt, that detachably tethers one athlete to another usually for training purposes.
BACKGROUND OF THE INVENTION
Reaction training belts, which are also known as shadow belts, are commonly used by athletes to develop and improve their agility, reaction time and quickness. In general, a reaction belt detachably tethers one athlete to another. During use, one of the athletes attempts to move away from the other athlete so as to detach the tether between them. The other athlete attempts to move with the first athlete so as to prevent the tether from becoming detached. The second athlete attempts to keep the tether attached to the other athlete as long as possible.
Athletes can perform a variety of pursuit and reaction drills that add another dimension to training. Ideally, athletes are matched evenly for speed, quickness and agility so that it provides a greater challenge and forces the drill to last longer. The drill can match sport specific positions against each other and can be focused on an area similar to the distance each position runs or moves in a game.
Known reaction belts are usually detachably secured with a detaching structure that do not allow for the release resistance to be adjusted. For example, know reaction belts attach via hook and loop material and the like.
Moreover, these known attachment structures tend to deteriorate over time, thereby compromising their durability.
SUMMARY OF THE INVENTION
Accordingly, despite the known reaction belts, there remains a need for a cost effective training belt that offers the ability to vary the release resistance and that allows the release resistance to remain relatively constant throughout the life of the belt. These and other improvement is found in the present invention.
In one disclosed embodiment, the reaction belt has a first and second belt detachably secured together with a detaching structure that can connect the first and second belts together in at least two different ways. Each of the connecting ways offers a different release resistance; thereby a user can select the desired release resistance by selecting which way to connect the two belts together.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
A reaction training belt system 10 having a first belt 10a detachably secured to a second belt 10b by a detaching structure 12 that allows the release resistance to be adjusted is shown in FIGS. 1-3D.
The first and second belts 10a, 10b are formed of a flexible material, and they are preferably adjustable so as to be operably secured around an athlete as best shown in FIG. 2. Preferably, the distal ends of each belt 10a, 10b are joined to the detaching structure 12.
One possible detaching structure 12 is shown in FIGS. 1-3D. Preferably, the detaching structure 12 has a male portion 16 operably received within a female portion 14. Protrusions 15 extending from the sides of the male portion operably engage one pair of a plurality of openings 18a-c, aligned on the female portion as shown. Each pair of openings 18a-c is preferably sized so as to offer a different degree of release resistance at which the protrusions 15 will detach from the opening 18a-c when the two belts 10a-10b are urged in different directions from each other.
Preferably, at least three different release settings are engineered into the detaching structure so an athlete can first set it on the 3rd clip position (pushed all the way in as shown in FIG. 3A) for the highest resistance. At this resistance level, the force required to “break” the female portion free from the two tab positions is preferably about 25 pounds. Athletes first using the training belt system 10 should start on this setting. As they progress, they can clip the detaching structure on the middle setting (medium resistance shown in FIG. 3B) or on the first setting (lightest resistance shown in FIG. 3C).
Alternatively, a plurality of spaced apart protrusions 15 may be positioned on each side of the male portion 16 and aligned so as to allow the user to select the number of protrusions 15 that will engage the openings 18a-c. For example, with three pairs of spaced apart protrusions 15 on the sides of the male portion 16, the user can position the male portion 16 so that each pair of protrusions operably engages one of the pair of openings 18a-c. This configuration provides the maximum amount of protrusions engaging the maximum amount of openings 18a-c, thereby providing the highest degree of release resistance.
To reduce the amount of release resistance, the user slides the male portion away from the female portion, so that fewer protrusions engage openings 18a-c. It can be appreciated that the least amount of release resistance can be achieved simply by continuing to slide the male portion away from the female portion so that only one pair of protrusions 15 operably engage one pair of openings 18a. 
The detaching structure as previously described provides consistent and reliable tension each time. Moreover, the defined release resistance for each configuration will not degrade over time like with hook and loop material and the like. The detaching structure can also be used for additional resistance training if scaled up or used in its present form for additional reaction training drills.
Having described and illustrated the principles of our invention with reference to a preferred embodiment thereof, it will be apparent that the invention can be modified in arrangement and detail without departing from such principles. Accordingly, in view of the many possible embodiments to which the principles may be put, it should be recognized that the detailed embodiments are illustrative only and should not be taken as limiting the scope of our invention. Accordingly, we claim as our invention all such modifications as may come within the scope and spirit of the following claims and equivalents thereto.
