Non-motorized vehicle

Abstract

A non-motorized foot board scooter including a frame, a front wheel and a rear wheel, a steering assembly, and a drive train. The drive train includes a kick arm that rotates the rear wheel when the kick arm is pushed backwards by the rider. The kick arm is centered with the rear wheel and a kick guard is located between the rear wheel and the kick arm. A first sprocket is mounted to the arm. The rear wheel has an associated second sprocket that is connected to the rear wheel via a clutch. A chain is mounted to the frame and extends around the first and second sprockets. The chain is routed such that as the arm is rotated the chain is drawn across the second sprocket thereby rotating the drive wheel.

1 . A non-motorized vehicle, comprising:
 A. an elongate frame having a length and a width; and   B. a drive train including:
 i. an arm rotatably disposed on the frame and extending upwardly therefrom; 
 ii. a first sprocket mounted on said arm; 
 iii. a drive wheel and an associated second sprocket; and 
 iv. a chain including a first end portion mounted to said frame at a first location, extending around said first and second sprockets, and including a second end portion secured to a movable mount, whereby movement of said movable mount causes said first sprocket to rotate independently of said arm, said chain being routed such that as said arm is rotated said chain is drawn across said second sprocket thereby rotating said drive wheel. 
   
     
     
         2 . A non-motorized vehicle according to  claim 1 , including a hand lever and a cable connected between said hand lever and said movable mount, whereby movement of said hand lever causes said movable mount to change positions. 
     
     
         3 . A non-motorized vehicle according to  claim 2 , wherein said movable mount comprises a lever arm pivotaly mounted to said frame and including a first lever end and an opposing second lever end, wherein said second end portion of said chain is secured to said first lever end and said cable is secured to said second lever end. 
     
     
         4 . A non-motorized vehicle according to  claim 1 , wherein said arm extends from the center of the width of said frame. 
     
     
         5 . A non-motorized vehicle according to  claim 1 , wherein said first sprocket is mounted offset from the center of the width of said frame. 
     
     
         6 . A non-motorized vehicle according to  claim 4 , wherein said frame includes a. guard disposed between said arm and said drive wheel. 
     
     
         7 . A non-motorized vehicle according to  claim 1 , wherein said chain extends around a pulley wherein said pulley is resiliently biased against said chain. 
     
     
         8 . A non-motorized vehicle according to  claim 1 , wherein said second sprocket is connected to said drive wheel with a clutch. 
     
     
         9 . A non-motorized vehicle according to  claim 8 , wherein said clutch is a one-way needle bearing. 
     
     
         10 . A non-motorized vehicle, comprising:
 A. an elongate frame; and   B. a drive train including:
 i. an arm rotatably disposed on the frame and extending upwardly therefrom: 
 ii. a first sprocket including a plurality of teeth disposed about a first axis and rotatably mounted to said arm about a second axis that is offset from said first axis; 
 iii. a drive wheel and an associated second sprocket; and 
 iv. a chain including a first end portion mounted to said frame at a first location, extending around said first and second sprockets, and including a second end portion mounted to said frame at a second location, said chain being routed such that as said arm is rotated said chain is drawn across said second sprocket thereby rotating said drive wheel. 
   
     
     
         11 . A non-motorized vehicle according to  claim 10 , wherein said arm extends upwardly from the center of the width of said frame. 
     
     
         12 . A non-motorized vehicle according to  claim 11 , wherein said frame includes a guard disposed between said arm and said drive wheel. 
     
     
         13 . A non-motorized vehicle according to  claim 11 , wherein said first sprocket is mounted offset from the center of the width of said frame. 
     
     
         14 . A non-motorized footboard scooter, comprising:
 A. an elongate frame having a length and a width;   B. a steering assembly pivotal disposed on said frame, said steering assembly including a front wheel and handlebars; and   C. a drive train including:
 i. an arm rotatably disposed on said frame; 
 ii. a first sprocket including a. plurality of teeth disposed about a first axis and rotatably mounted to said arm about a second axis that is offset from said first axis; 
 iii. a rear wheel connected to an associated second sprocket via a clutch; and 
 iv. a chain including a first end portion mounted to said frame at a first location, extending around said first and second sprockets, and including a second end portion mounted to said frame at a second location, said chain being routed such that as said arm is rotated said chain is drawn across said second sprocket thereby rotating said rear wheel. 
   
     
     
         15 . A non-motorized footboard scooter according to  claim 14 , including a pulley resiliently biased against said chain. 
     
     
         16 . A non-motorized footboard scooter according to  claim 14 , wherein each of said plurality of teeth are disposed equidistant from said first axis. 
     
     
         17 . A non-motorized footboard scooter according to  claim 14 , wherein said first sprocket is mounted offset from the center of the width of said frame. 
     
     
         18 . A non-motorized footboard scooter according to  claim 14 , wherein said second end portion of said chain is secured to a movable mount, whereby movement of said movable mount causes said first sprocket to rotate independently of said arm, 
     
     
         19 . A non-motorized footboard scooter according to  claim 18 , including a hand lever mounted on said handlebars and a cable connected between said hand lever and said movable mount, whereby movement of said hand lever causes said movable mount to change positions, 
     
     
         20 . A non-motorized footboard scooter according to  claim 14 , including a guard disposed between said arm and said rear wheel.
