Treadmill

Abstract

A treadmill comprised of two pedal assemblies for the user to tread alternatively with both feet up and down; each pedal assembly having at its base pivoted with a front and a rear dancer; the tails of both dancers being respectively pivoted to the front and the rear ends of a pedal; a linking member being disposed at where between both pedal assemblies; and both pedals normally maintaining horizontal status as both pedal assemblies alternatively move up and down to allow user to easily maintain balance and better mobility for both feet.

1 . A treadmill is essentially comprised of a base and two pedal assemblies that alternatively move up and down; each pedal assembly including a pedal, and pivoted at the base a front dancer and a rear dancer; both ends of the front and the rear dancers being respectively pivoted to the front and the rear of the pedal; a linking member provided between both pedal assemblies being pivoted to a shaft; and two connection rods being respectively coupled to where between the rear dancers of both pedal assemblies and the linking member.  
     
     
         2 . The treadmill of  claim 1 , wherein an upper clamping plate and a lower clamping plate are pivoted to the shaft respectively at where above and below the linking member; a first bolt inserted through both clamping plates at their ends opposite to the shaft; a resistance plate disposed to the linking member extending to the peripheral of the first bolt; the resistance plate sliding between both of the upper and the lower clamping plates; and the spacing between both of the upper and the lower clamping being adjustable to change the sliding capability of the resistance plate thus to regulate the force applied by the user to both pedal assemblies.  
     
     
         3 . The treadmill of  claim 2 , wherein a second bolt is laterally provided to the base at the rear end of the shaft; the tail of the second bolt and the lower end of the shaft pushing against each other; and the angle of the shaft being adjustable by turning the second bolt to change the relative positions between the linking member and both pedal assemblies, thus to adjust the height of the pedal.  
     
     
         4 . The treadmill of  claim 3 , wherein a base plate is disposed to the base to be fastened by the second bolt.  
     
     
         5 . The treadmill of  claim 1 , wherein a friction plate that contacts the resistance plate is disposed between the upper and the lower clamping plates.  
     
     
         6 . The treadmill of  claim 2 , wherein a resilient pad is provided between the first bolt and the upper clamping plate.  
     
     
         7 . The treadmill of  claim 1 , wherein buffer member is provided to the base at where in relation to the rear end of the pedal.  
     
     
         8 . The treadmill of  claim 6 , wherein the buffer member relates to a compression coil.  
     
     
         9 . The treadmill of  claim 1 , wherein both pedal assemblies are laid out at a given included angle.  
     
     
         10 . The treadmill of  claim 2 , wherein the first bolt is provided at its top a nut.  
     
     
         11 . The treadmill of  claim 3 , wherein both of the first and the second bolts are each disposed at their tops a nut.
