Definitions

Unless otherwise stated, the words “up”, “down”, “top”, “bottom”, “upper”, and “lower” should be interpreted within a gravitational framework. “Down” is the direction that gravity would pull an object. “Up” is the opposite of “down”. “Bottom” is the part of an object that is down farther than any other part of the object. “Top” is the part of an object that is up farther than any other part of the object. “Upper” may refer to top and “lower” may refer to the bottom. As a non-limiting example, the upper end of a vertical shaft is the top end of the vertical shaft.


As used in this disclosure, an “aperture” may be an opening in a surface or object. Aperture may be synonymous with hole, slit, crack, gap, slot, or opening.


As used herein, the words “couple”, “couples”, “coupled” or “coupling”, may refer to connecting, either directly or indirectly, and does not necessarily imply a mechanical connection.


As used in this disclosure, “elastic” may refer to a material or object that deforms when a force is applied to stretch or compress the material and that returns to its relaxed shape after the force is removed. A material that exhibits these qualities is also referred to as an elastomeric material.


As used in this disclosure, “flexible” may refer to an object or material which will deform when a force is applied to it, which will not return to its original shape when the deforming force is removed, and which may not retain the deformed shape caused by the deforming force.


As used herein, “front” may indicate the side of an object that is closest to a forward direction of travel under normal use of the object or the side or part of an object that normally presents itself to view or that is normally used first. “Rear” or “back” may refer to the side that is opposite the front.


As used in this disclosure, “horizontal” may be a directional term that refers to a direction that is perpendicular to the local force of gravity. Unless specifically noted in this disclosure, the horizontal direction is always perpendicular to the vertical direction.


As used in this disclosure, “orientation” may refer to the positioning and/or angular alignment of a first object relative to a second object or relative to a reference position or reference direction.


As used in this disclosure a “pulley” may be a wheel with a grooved rim around which a cord (or other form of rope, line, belt, or cable) passes. The pulley may be used to change the direction of a force applied to the cord. In some embodiments, pulleys may be used in groups of two or more to convey a force from one pulley to all other pulleys in the group via a belt. In some embodiments, a pair of opposing pulleys may be used to guide a cord along a path.


As used herein, “ready position” or “ready stance” may refer to the stance of an athlete wherein the feet are separated to shoulder width and facing forward, the knees are bent, the hips are back, and the torso is inclined forward to a position above the knees.


As used herein, “reel” may refer to a cylindrical object with side walls around which a wire, filament, thread, cord, cable, string, line, rope, hose, tubing, or other rope-like object is wound.


As used in this disclosure a “strap” may be a strip of leather, cloth, nylon, plastic, thin metal, rubber, or other flexible material, that is used to fasten, secure, carry, or hold onto something. A strap is sometimes used in conjunction with a buckle or other types of fasteners.


With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention described above and in FIGS. 1 through 4, include variations in size, materials, shape, form, function, and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the invention.
