Vibration isolation exercise machine

Abstract

An exercise apparatus with suspension system is provided. The exercise apparatus may include one or more of the following; a frame suspension system, a base suspension system, a deck suspension system, or a chassis dampening system. The advantage of exercising apparatus with suspension system is that it may prevent or mitigate vibration and sound disturbances of the exercise apparatus when it is used.

What is claimed is: 
     
         1 . An apparatus for exercising, comprising:
 a chassis;   a frame suspension system, wherein the frame suspension system includes a chamber and a piston, and wherein the chamber is at least partially filled with a magnetorheological fluid; and   a deck movably connected to the chassis via the frame suspension system.   
     
     
         2 . The apparatus of  claim 1 , wherein the piston includes one or more piston channels. 
     
     
         3 . The apparatus of  claim 2 , wherein the magnetorheological fluid is configured to flow through the one or more piston channels when the piston moves inside of the frame suspension system. 
     
     
         4 . The apparatus of  claim 1 , wherein the frame suspension system is connected to at least one of a sidewall of the chassis and a bottom wall of the chassis. 
     
     
         5 . The apparatus of  claim 1 , further including an arm, wherein a first end of the arm is connected to the piston and a second end of the arm is connected to the deck. 
     
     
         6 . The apparatus of  claim 4 , wherein the frame suspension system allows the deck to move relative to the chassis when the piston moves inside of the frame suspension system. 
     
     
         7 . The apparatus of  claim 4 , wherein the piston includes an electromagnetic coil. 
     
     
         8 . The apparatus of  claim 7 , wherein the electromagnetic coil is configured to generate a magnetic field. 
     
     
         9 . The apparatus of  claim 8 , wherein a high intensity value of the magnetic field reduces a piston movement inside of the frame suspension system, and wherein a low intensity value of the magnetic field increases the piston movement inside of the frame suspension system. 
     
     
         10 . An exercise apparatus for reducing vibration to ground, comprising:
 a chassis;   a chassis support system, wherein the chassis support system is configured to support the chassis relative to ground; and   a chassis dampening system connected to the chassis support system.   
     
     
         11 . The exercise apparatus of  claim 10 , wherein the chassis dampening system is a magnetic suspension system. 
     
     
         12 . The exercise apparatus of  claim 11 , wherein the chassis dampening system includes a first magnet and a second magnet and a space between the first magnet and the second magnet, wherein the first magnet and the second magnet have same polarity. 
     
     
         13 . The exercise apparatus of  claim 10 , wherein the chassis dampening system is an air suspension system. 
     
     
         14 . The exercise apparatus of  claim 13 , wherein the chassis dampening system includes an air supply unit, an air reservoir and air spring, wherein the air supply unit provides air to the air reservoir and the air reservoir provides air to the air spring. 
     
     
         15 . The exercise apparatus of  claim 10 , wherein the chassis dampening system is a spring suspension system. 
     
     
         16 . The exercise apparatus of  claim 15 , wherein the chassis dampening system includes a first element, a second element, and a spring located between the first element and the second element, wherein the spring is configured to provide force towards the first element and the second element. 
     
     
         17 . The exercise apparatus of  claim 10 , wherein the chassis dampening system is a shock absorption system. 
     
     
         18 . The exercise apparatus of  claim 17 , wherein the chassis dampening system includes a first element, a second element and a shock absorbing material located between the first element and the second element. 
     
     
         19 . The exercise apparatus of  claim 18 , wherein the shock absorbing material includes one or more of rubber or silicone. 
     
     
         20 . A method for adjusting dampening force on a dampening system of an exercise apparatus, comprising:
 detecting a trigger to adjust a first dampening force; and   increasing a magnetic field intensity to solidify a magnetorheological fluid to generate a second dampening force, and wherein the second dampening force is less than the first dampening force.
