Brief Patent Description - Full Patent Description - Patent Claims

The Patent Description & Claims data below is from USPTO Patent Application 20070287612, Maximum muscle strengthening resistance device.

1. A Maximum Muscle Strengthening Resistance Device comprising,(a) A Resistance cylinder set that consist of one cylinder, one piston, one automatic valve, one oil cannel, two hoses, one steel wire connecting loop, one oil pressure sensor, one pair of lead wires to the oil pressure sensor, and one resistance control opening.(b) A power unit that is a hydraulic pump.(c) A power clutch that attached to the electric power motor in the electric power motor version.(d) A steel wire that connects the piston to the exercising handle.(e) An exercising handle that the exercising person pulls for strengthening exercises.(f) An oil tank that provides the oil for the said cylinder of resistance cylinder set and receives the back flow oil from the said cylinder.(g) A monitor that is connected to the oil pressure sensor in the resistance cylinder set and allows the exercising person monitors the amount of force he is exerting for the exercises.

2. The device of claim 1 includes 2 versions;(a) Hydraulic pump version: the pulling force for eccentric movement is provided by a hydraulic pump.(b) Electric power motor version: the pulling force for the eccentric movement is provided by an electric power motor.

3. A device of claim 1 wherein a person who exercises using this device pulls the said exercising handle actively during the concentric exercise cycle, that causes the said piston in the said resistance cylinder set moves outward forcing the oil inside the said cylinder passes through the said resistance control opening that gives the exercising person a resistant force against his pulling force.

4. A device of claim 1 wherein the said power unit (either hydraulic pump) provides the force to push the said piston inward during the eccentric exercise cycle, it causes the said exercising handle to move toward the eccentric direction, and by attempting to stop the said eccentric movement of the exercising handle against the pulling force of the said power unit, the exercising person performs eccentric exercises exerting his maximum power.

5. A device of claim 1 wherein the said automatic valve opens the said resistance adjusting opening automatically during the concentric exercises and allows the oil in the said resistance cylinder set forcefully passes through the opening to produce a resistant force against the pulling force of the said exercising person.

6. A device of claim 1 wherein the said automatic valve adjusts the size of the said resistance adjusting opening so that allows to set various levels of resistance during the concentric exercises.

7. A device of claim 1 wherein the said automatic valve closes the said resistance adjusting opening during the eccentric exercises in the said hydraulic pump version allowing the hydraulic pump pushes the said piston inward to produce the eccentric movement.

8. A device of claim 1 wherein the said clutch of the said electric power motor is opened during the concentric exercise cycle in the electric power motor version that frees the said piston from the said electric power motor and enables the said exercising person to perform the said concentric exercise.

9. A device of claim 1 wherein the said oil pressure sensor senses the amount of inside pressure of said cylinder and shows it on the said monitor.

10. A device of claim 1 wherein the location of the said pressure sensor is not limited to inside of the cylinder, and it can be installed onto any other places like between the piston and the steel wire.

11. A device of claim 1 wherein the said exercising handle in (e) clause is just one example of various exercising harnesses for explanatory purposes and is not intended to limit the application of this device to certain type of exercise, as those skilled in the art will make modifications to the invention for particular exercises.
