Pogo device

Abstract

A more stable pogo stick device, which may or may not be steerable, employs multiple spring legs, at least one of which can have an alterable spring rate. To steer in a direction, the alterable spring rate is employed, whereupon the pogo will move in the direction of the softer spring. Further, a pogo stick with enhanced stability and safety is provided by employing multiple, vertical springing legs. A pogo with enhanced stability and widened foot platform provides the ability for a single rider to perform tricks and/or to allow multiple riders to jump together at the same time.

What is claimed is:  
     
         1 . A steerable pogo device comprising: 
 a first leg having a first substantially fixed spring rate; and    a second leg having a variable spring rate for enabling steering.    
     
     
         2 . A pogo device comprising: 
 at least two independent suspension legs, wherein said legs are substantially vertical in orientation to provide for enhanced stability.    
     
     
         3 . The pogo device according to  claim 2 , wherein the number of legs is 3, to provide for optimum X and Y stability.  
     
     
         4 . The pogo device according to  claim 2 , wherein one of said legs is denoted a forward leg, wherein said forward leg has a variable spring rate for assisted steering in the forward direction.  
     
     
         5 . The pogo device according to  claim 4 , wherein the number of legs is 3.  
     
     
         6 . The pogo device according to  claim 5 , wherein said legs other than said forward leg have a variable spring rate for enabling steering left, right, in addition to the steering in the forward direction provided by said front leg.  
     
     
         7 . A pogo with a boost mechanism, mechanical or pneumatic, to either preload a spring or pump up a cylinder to allow the rider to actuate it after charging for a “boost” in vertical jumping.  
     
     
         8 . The device in accordance with  claim 1 , further comprising interchangable convex feet of large diameter for providing further stability and to enable use without abusing the floor.  
     
     
         9 . The device in accordance with  claim 1 , further comprising interchangeable springs of varying spring rate.  
     
     
         10 . The device in accordance with  claim 1 , further comprising adjustable preload of springs to accommodate different rider weights.  
     
     
         11 . The device in accordance with  claim 1 , wherein the spacing width between ones of said legs is adjustable to vary the amount of stability enhancement and amount of steering assistance generated.  
     
     
         12 . The device in accordance with  claim 1 , comprising a perimeter bumper for safety and to reduce damage to stationary objects.  
     
     
         13 . The device in accordance with  claim 1 , further comprising a large footpad for the rider's feet for greater comfort and safety as well as permitting different rider positions for doing tricks.  
     
     
         14 . The device in accordance with  claim 1 , further comprising a handle bar adapted for gripping by plural riders.  
     
     
         15 . The device according to  claim 14 , wherein said handle bar is a substantially circular handlebar.  
     
     
         16 . The device according to  claim 14 , further comprising a footpad to allow multiple riders to face each other and jump together.  
     
     
         17 . The device according to  claim 16 , wherein said footpad is a substantially circular footpad.  
     
     
         18 . The device in accordance with  claim 1 , wherein said variable spring rate is activated by twisting an activation member.  
     
     
         19 . The device in accordance with  claim 1 , wherein said variable spring rate is activated by turning an activation member.  
     
     
         20 . The device in accordance with  claim 1 , wherein said variable spring rate is activated by activating a lever member.  
     
     
         21 . The device in accordance with  claim 8 , wherein said feet are substantially larger in diameter than the diameter of the spring support member.  
     
     
         22 . The device in accordance with  claim 2 , comprising a substantially rigid central pole member.  
     
     
         23 . The device in accordance with  claim 2 , wherein said legs comprises spring action legs.  
     
     
         24 . The device in accordance with  claim 23 , wherein said legs are independent in their spring action relative one another.  
     
     
         25 . The device in accordance with  claim 23 , wherein said legs are constrained to spring substantially in one axis.
