  • Patent number: 5286243
    Abstract: A variable resistance exercise device is provided which enables a user to select from an almost limitless set of resistance curves having various shapes and amplitudes. These results are achieved using a fixed baseline resistance and a variable resistance generated by a torque arm assembly. Preferably, the torque arm assembly either has a vertical diametric torque arm and two horizontal radial torque arms which are perpendicular to the vertical torque arm or two diametric torque arms which are perpendicular to each other. By varying the position of a weight member on each of these arms, as well as the ratio of the net horizontal torque and the vertical torque generated by the weight members, the baseline resistance force that the user experiences can be infinitely varied. Additionally, through the use of a gear assembly, the user can achieve a force variance during the exercise which is greater than the minimum force experienced during the exercise.

  • Patent number: 5263914
    Abstract: A first end of a lever pivots about a fixed axis as a second end is raised and lowered by the user. A carriage is disposed on the lever and is designed to travel the length of the lever between the first and second ends. A belt is coupled to a weight and to the carriage through a series of pulleys. The lever is shaped so that the weight neither raises nor lowers as the carriage travels from one end of the lever to the other. The distance that the weight travels in response to movement of the second end is thus proportional to the position of the carriage on the lever. By moving the carriage to numerous positions between the first and second ends of the lever, the torque needed to lift the weight and the distance by which the weight moves may be varied correspondingly in numerous increments over a very large range. A number of different user interfaces may be coupled to the lever for creating an equal number of different weight training machines.

  • Patent number: 5190511
    Abstract: A simplified fluid flow resistance device and exercise equipment utilizing the same is disclosed. In a preferred embodiment, a rotating shaft is centered in a fluid filled sealed cylinder. A rotor is connected to the shaft and a baffle is connected to the internal wall of the cylinder. Rotation of the rotor in the cylinder drives fluid through bores in the baffle. Adjustable spring loaded ball valves are situated in at least two bores passing through the baffle so that resistance to fluid flow through the baffle in opposite directions can be controlled. The simplified design of the fluid flow resistance device of the present invention utilizes less materials so as to have minimal weight; thus the fluid resistance device is ideal for use in spacecrafts. Further, by use of spring loaded one way valves, the device can be used in any orientation, and a minimum resistance to motion of a lever arm connected to the fluid resistance device can be obtained.
