Patent number: 5624353Abstract: A weight training machine having a dynamically controlled resistance capability. The user exercises by causing an exercise arm to pivot. Pivoting coaxially with the exercise arm, is a pivot arm which supports a secondary weight. To pivot the exercise arm, the user must overcome a primary resistance and the torque on the pivot arm due to the secondary weight. The torque due to the secondary weight can be dynamically varied by varying the position of the secondary weight on the pivot arm. Thus the resistance experienced by the user, can be varied within a predetermined range. A force input mechanism engageable with a body part of the user is also disclosed which reduces discomfort to the user during exercise.Type: GrantFiled: July 30, 1996Date of Patent: April 29, 1997Inventor: Scott G. Naidus

Patent number: 5618250Abstract: An aerobic exercise machine is disclosed in which aerobic exercise may be conducted using the trunk and hip flexor and extensor muscles. The exercise machine does not require dynamic use of the extremities. The exercise machine provides a uniform level of resistance to contact means adapted to contact both the anterior and posterior surfaces of the trunk of the person exercising. The exercise machine enables exercise by flexion and extension of the trunk muscles and flexion and extension of muscles controlling the hip joint. An energy storage device is utilized to provide uniform resistance to movement in both directions and during the reversal of directions. A counter is provided and various levels of resistance may be selected by switching selected amounts of resistance across the output of a generator driven by the motion of the exerciser.Type: GrantFiled: September 2, 1994Date of Patent: April 8, 1997Inventor: Todd M.

Patent number: 5597373Abstract: A system for isolating, evaluating and exercising the muscle groups of the human hand, wrist, arm and shoulder including an adaptable detector for interpreting the cardinal movements of at least one muscle group of the hand during flexion, extension, or deviation of the wrist, or abduction, opposition, flexion or hyperextension of individual digits of the hand. The detector translates the movements of the muscle group into rotational data for the system and effectively isolates the movements of the muscle group so that the movements of other muscle groups of the body are not detected by the system. The system also includes a controlled resistance coupled to the detector which provides a variable resistance against the muscle group and ascertains the force applied to the detector by the movements of the one muscle group. The resistance can be varied to provide isotonic, isokinetic, or isometric modes of testing against said at least one muscle group.Type: GrantFiled: November 8, 1991Date of Patent: January 28, 1997Assignee: Cedaron Medical, Inc.Inventors: Malcolm Bond, Gary Engle, Joseph J.

Patent number: 5573486Abstract: It is critical to prevent muscular damage to an athlete in a machine that produces a restraining force that must be overcome in the initial part of an exercise stroke. This is achieved by a precise and accurate type of control system by which the athlete safely and surely control the initial restraining force magnitude. With a reliable vernier type control device the athlete then may "inch-by-inch" increase the restraining force as the muscles become able to overcome greater forces in the manner the proverbial strong man lifts a calf each day so that he can lift a full grown cow eventually. In a preferred embodiment of this vernier type control the restraining device comprises an electromagnet with a retained magnetic member coupled to the athlete by an intermediate muscular operated linkage.Type: GrantFiled: January 23, 1995Date of Patent: November 12, 1996Inventor: Evgeni Beliakov

Patent number: 5569121Abstract: A torque generator device for simulating in physical exercise apparatus a load opposing a force exerted by a user includes an asynchronous motor controlled by a variable speed drive of the flux vector control reversible type whose current is controlled by a torque regulator loop. The variable speed drive fixes the flux in the motor so that the torque can be controlled independently. The torque regulator loop processes measurements from a force sensor which it compares with a force set point to control the current fed into the motor by the variable speed drive. The device thus generates a constant torque which opposes the force exerted by the user.Type: GrantFiled: August 17, 1994Date of Patent: October 29, 1996Inventor: Bruno Sellier
