  • Patent number: 5624353
    Abstract: 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.

  • Patent number: 5356360
    Abstract: An adjustable lever arm--variable resistance cam assembly employing a cam for producing therefrom a variable resistance force when a constant resistance force is applied thereto and in which the lever arm may be initially positioned at a range of angular positions without thereby affecting the variable resistance force produced by the cam at each particular angular position of the lever arm upon rotation thereof. The adjustable lever arm--variable resistance cam assembly may be employed in a weight lifting machine or device of the type having a rotating lever arm for application of weight lifting force by the user. The assembly allows the user to angularly adjust the initial position of the lever arm in relation to the axis of the cam and, nevertheless, maintain the cam in appropriate relation with the constant resistance force. The variable resistance force produced by the cam will then not vary with respect to positioning of the lever arm as rotated during exercise.
