ABSTRACT:
FIELD OF THE INVENTION
This invention relates to specialized exercising apparatus and methods for muscular development in athletes to increase the speed and strength of an athlete's stroke when departing from an initial position, and more particularly it relates to such devices employing resistant forces at threshold levels to be overcome by an athlete's stroke away from the initial position.
BACKGROUND ART
From my U.S. Pat. No. 5,176,599, Jan. 5, 1993 it is known that magnetically attracted members may provide threshold forces to condition the muscles of boxers for strengthening and speeding up the delivery of boxing punches. However, complex and expensive equipment is required, which is restricted to the boxing sports. Furthermore operation of such machines required tethers that interfered with and distorted normal follow through strokes.
It is seen from U.S. Pat. No. 4,749,189, Jun. 7, 1988 by S. M. Frank for Exercise Machine for Hockey Players, that the same problem of interference with and distortion of a follow through stroke of a hockey stick was imposed.
Accordingly it is an objective of this invention to improve the state of prior art methods and apparatus for muscular development of an athlete for delivering a faster more powerful stroke.
More explicitly it is an objective to both simplify the nature and lower the cost of exercising machines, while at the same time unexpectedly improving the functional performance of exercising machines for athletes.
Other objects, features and advantages will be found throughout the following description, drawings and claims.
DISCLOSURE OF THE INVENTION
This invention provides an inexpensive athletic exercising system for development of muscles of the athlete to increase the velocity and strength of movement of a body member stroke away from an initial position toward a further position, typically an impact point. A set of two members, typically magnetic members hereinafter described in more detail in a preferred embodiment, are held together in a mated position until separated by overcoming a predetermined magnetic separating force. Electro-magnetic members permit the separating force to be variably controlled to challenge the athlete as the muscular actions improve. The athlete by manual exertion separates the two magnetic members, thus exercising and developing the stroking muscles for stronger and faster movement away from a starting point.
Thus, greater athletic capabilities are developed for impacting a ball, a boxer's body, or a hockey puck, etc. Similarly non-impact skills may be developed, such as a faster start to first base, or foot races, or a more powerful accelerated sprint in a football play using the teachings of this invention.
While alternative held-together-and-separable-under-tension devices may be substituted for two magnetically attracted members, such as adhesively attached, frictionally bonded, or integrally connected members formed in one piece that can be catastrophically broken apart, nondestructive and thus reusable magnets are the preferred embodiment as discussed in detail hereinafter for illustrating the nature and spirit of the invention with reference to FIG.

.
A first magnetic member is affixed to a movable athletic implement, such as a tennis racquet, ball bat, hockey stick, boxing glove, shoe, etc. to be manipulated by said athlete through an athletic stroke. The second magnetic member is restrained at a fixed position. The two magnetic members comprise at least one permanent or electro-magnet and the two members are arranged to mate and exhibit a predetermined separation force to separate them. The first magnetic member is preferably unrestrained by tethering or a mated position. Thus, it breaks away for freely moving with an athlete's body member in a follow through athletic stroke when the magnetic retention bond with the first magnetic member is broken. A significant advantage is that magnetic members may be light weight and small in size so that they do not tend to interfere with normal stroke paths or follow through action of the athlete after the initial magnetic bonding force is broken.
This system permits an athlete to develop strength and speed in muscular reaction for critical athletic strokes by manual manipulation of the athletic implement by an athlete's body member to overcome the predetermined initial threshold bonding force between the magnetic members. This system following the unbonding of the magnetic members, permits unrestrained movement of the athlete's body member in a follow through action, thereby avoiding abnormal restraints generally imposed by prior art exercising devices such as heretofore discussed requiring tethers or harnesses to be attached to athletic implements such as a boxing glove or a hockey stick.
Other features and advantages of the invention will be found throughout the following description, claims and accompanying drawings.
