Device for increased loading while running or sprinting

Abstract

The invention is a training device that operates to make runners run faster. More particularly, the training device uses increased loading as an athlete moves it from one point to another either by running or by walking.

What is claimed is: 
     
         1 . A device for increasing load while in motion, comprising:
 a. A frame having a front end and back end positioned oppositely to said front end;   b. A handle for moving said device, said handle being attached to said back end of said frame;   c. At least two rear movable members attached to said back end of said frame;   d. At least one front movable member attached to said front end of said frame;   e. A movable weight bearing device attached to said frame, said movable weight bearing device operably moving between said back end of said frame and said front end of said frame when said device is in motion.   
     
     
         2 . The device of  claim 1  wherein said movable weight bearing device comprises a platform, said platform being configured to receive a load. 
     
     
         3 . The device of  claim 2  wherein said load comprise one or more weighted objects. 
     
     
         4 . The device of  claim 1  wherein said movable weight bearing device comprises a sprocket and roller chain system. 
     
     
         5 . The device of  claim 4  wherein said sprocket and roller chain system is actuated by said at least two movable members attached to said back end of said frame. 
     
     
         6 . The device of  claim 4  wherein said sprocket and roller chain system transfers said load linearly along said frame of said device. 
     
     
         7 . The device of  claim 1  wherein said load increases as said device is moved in a linear direction. 
     
     
         8 . The device of  claim 7  wherein said load is increased in a linear direction. 
     
     
         9 . The device of  claim 8  wherein said load is increased as said load moves from said back end of said frame to said front end of said frame. 
     
     
         10 . The device of  claim 1  wherein said load increases upon said at least one movable member as said device moves linearly. 
     
     
         11 . The device of  claim 10  wherein said athlete is caused to work harder by increase of said load onto said one movable member. 
     
     
         12 . The device of  claim 1  wherein said movable weight bearing device comprises a gradual braking system. 
     
     
         13 . The device of  claim 12  wherein said gradual braking system comprises four springs, two brake pads and two points of attachment connected to said rolling chain. 
     
     
         14 . The device of  claim 12  wherein said gradual braking system is actuated by said at least two movable members attached to said back end of said frame. 
     
     
         15 . The device of  claim 12  wherein said gradual braking system actuates by narrowing of said frame. 
     
     
         16 . The device of  claim 1  wherein movable weight bearing device moves reversibly linearly based upon the direction of linear motion of said device. 
     
     
         17 . The device of  claim 16  wherein said movable weight bearing device moves gradually back to said back end of said frame. 
     
     
         18 . The device of  claim 1  wherein said two movable members are wheels. 
     
     
         19 . A device for increasing load while in motion, comprising:
 a. A frame having a front end and back end positioned oppositely to said front end;   b. A handle for moving said device, said handle being attached to said back end of said frame;   c. At least two movable members attached to said back end of said frame;   d. At least one movable member attached to said front end of said frame; and   e. A graduated resistance system actuated upon linear motion of said device, said graduated resistance system providing increased resistance as said device moves linearly.   
     
     
         20 . The device of  claim 19  wherein said graduated resistance system is programmable. 
     
     
         21 . The device of  claim 20  wherein said graduated resistance system is computerized. 
     
     
         22 . The device of  claim 19  wherein said graduated resistance system is programmably releasable. (This is the training method in which a load is applied at the beginning of a sprint but then a runner is later released from that load.)
