Definitions

  • This invention relates to exercising and training machines. More particularly, this invention relates to exercising and training machines for exercising a person's ability to accelerate a portion of his body through a path of motion, such as which occurs during a baseball or golf swing.
  • exercising and training machines designed to exercise portions of a person's body.
  • the most predominant type of exercising and training machine utilizes weight resistance which, through repetition, builds the person's muscles.
  • United States Patent 4,296,924 disclose a torsion exercise apparatus including adjustable weights which may be raised by rotational movement of a wheel about a vertical axes to which is connected a pair of handles and crossbar for cradling the user's shoulders, arms and hands therein. Rotational movement of the user's torso causes the wheel to rotate about the vertical axis to raise and lower the weights, thereby exercising the user's torso.
  • an exercise and training machine which exercises a person's ability to accelerate a portion of his body through a path of motion, such a what occurs during the swinging of a baseball bat or a golf club.
  • an exercising and training machine which isolates individual muscle groups and measures acceleration of a portion of a person's body. Indeed, many professional athletes such a golfers and baseball players refrain from resistance weight training during season in fear of adversely affecting their flexibility and ability to swing their golf club or baseball bat in a controlled manner.
  • Another object of this invention is to provide an exercising and training machine which exercises and trains a person's ability to accelerate a portion of his body through a path of motion.
  • Another object of this invention is to provide an exercising and training machine which is to be utilized by golfers in exercising their golf swing.
  • Another object of this invention is to provide an exercising and training machine to be used by golfers in exercising their backswing.
  • Another object of this invention is to provide an energy absorbing exercising machine which allows the user to regulate the amount of resistance in accordance with the user's physical ability and which can, therefore, be used for rehabilitation of muscles.
  • Another object of this invention is to provide an energy absorbing exercising and training machine which allows a person to time the release of energy at the instant of the most importance.
  • the invention comprises an energy absorbing exercising and training machine for exercising a person s ability to accelerate a portion of his body through a path of motion, including an energy-storing device e.g. a flywheel rotatably connected to a frame by means of a pair of journal bearings.
  • a harness assembly is provided for connection to the portion of the person,s body to be exercised.
  • Means are provided for interconnecting the flywheel and the harness assembly allowing the flywheel to rigidly engage relative to the harness assembly upon acceleration of the harness assembly relative to the flywheel in a first direction along the path of motion of the body portion being exercised.
  • the interconnecting means also allows the flywheel to disengage and freely rotate relative to the harness assembly upon deceleration of the harness assembly relative to the flywheel.
  • the body portion being exercised may therefore be forcibly accelerated in the first direction along the path of motion against the inertia of the flywheel.
  • the flywheel Upon deceleration of the body portion, the flywheel disengages relative to the harness assembly thereby precluding the inertia of the flywheel from exerting a force on the body portion along the path of motion.
  • the interconnecting means comprises an overrunning clutch having an inner race mounted to a shaft which is connected to the flywheel and journaled in the pair of bearings and having an outer race connected relative to the harness assembly.
  • the exercising and training machine of the invention may be utilized in conditioning and training for many sports and other activities that encourage the rapid accelaration of a portion of the person's body, such as occurs in baseball, golf, and other swing-type activities.
  • the machine is also usable in exercising individual muscle groups that are customarily exercised through weight lifting exercises like bench presses, bi-ceps curls and overhead presses.
  • the exercising and training machine is described herein as being utilized in conditioning for golf by exercising the twisting acceleration of the golfer's torso and legs during a golf swing.
  • the exercising and training machine of the invention when utilized as a torso and legs exercising machine for golfers, the exercising and training machine of the invention comprises a stand which adjustably positions the flywheel, shaft, and overruning clutch in a position above the golfer's head, with the harness assembly connected to the lowermost end of the shaft by means of a universal joint, preferably a constant velocity universal joint.
  • the harness assembly comprises an inverted substantially U-shaped or V-shaped rigid configuration for fitting over the shoulders and upper torso of the golfer's body.
  • the universal joint allows the torso harness assembly to universally pivot during the golf swing.
  • the frame comprises a carriaged frame that is operatively connected to the stand by means of slide bearings which allow the frame, flywheel, shaft and torso harness assembly to freely reciprocate sideways above the golfer's head, the sideways movement being geared to the rotation of the torso harness of the shaft.
  • the shaft is preferably slidably journalled within the pair of journal bearings and the inner race of the over-running clutch to allow the shaft to easily reciprocate vertically.
  • the sideways movement of the carriaged frame, the vertical movement of the shaft, and the pivoting of the torso harness assembly via the universal joint allows tha golfer to exercise and be trained in a recommended golf swing which requires canting and vertical and sideways movement of the golfer's torso during the backswing and through the golf swing.
  • the golfer's torso may accelerate to his fullest ability and the energy created thereby forces the flywheel into accelerating rotational movement and such energy is absorbed.
  • the overrunning clutch disengages the shaft allowing the flywheel to freely rotate.
  • the inertia of the rotating flywheel does not exert a force on the golfer's torso once the golfer's torso begins to decelerate or stop. Over-twisting and possible physical damage are therefore precluded.
  • the exercising and training machine of the invention may additionally include means for providing resistance to the golfer's torso during the backswing and partial extension of the torso at the end of the backswing immediately prior to beginning the golf swing. More particularly, such means may comprise a cammed clutch for interconnecting the flywheel and the shaft.
  • the cammed clutch allows the flywheel to rigidly engage the shaft only during a predefined arc of rotation which corresponds to the arcuate path of motion of the backswing.
  • the flywheel is rigidly connected relative to the harness and provides inertial resistance to the golfer's torso during the backswing.
  • the inertia of the flywheel forces slight extension of the golfer's torso immediately prior to the golfer exerting energy by twisting his torso in the opposite direction corresponding to a golf swing thereby overcoming the inertia of the flywheel and reversing its direction.
  • the cammed clutch may be adjusted to disengage the flywheel from the shaft at a predefined end of the backswing to preclude overextension of the golfer's torso and possible physical damage.
  • a transducer may be operatively connected to the frame to sense the rotational speed of the flywheel over time, which information is then fed into a displayed device to inform the golfer of his progressive ability to accelerate the flywheel.
  • Additional transducers may also be operatively connected to the frame to sense the vertical movement of the shaft, the sideways shifting of the frame and the angular position of the torso harness assembly relative to the shaft. All of such information may then supplied to a computer and analyzed to determine the quality of the golf swing.
  • the exercising and training machine 10 of the invention comprises a carriaged frame 12 reciprocatably mounted within a vertically adjustable stand, generally indicated by numeral 14.
  • a flywheel 16 is rotatably mounted to the carriaged frame 12 by means of a shaft 18.
