Axle thread and bearing protector

Abstract

An axle thread protection system which simultaneously protects the skateboard wheel bearings from dust and debris. A plastic shield is used between the hanger of the skateboard truck and the skateboard wheel. The shield generally held adjacent to the exposed outer surface of the inner skateboard wheel bearing. A capping nut having a similar bearing-protector flange has a nut section coupled to a cage section that holds in place a locking ring and thread protector. The locking ring helps to reduce vibration and keep the capping nut on the threaded end of the skateboard axle while a thread protector reduces injury to the threaded axle end of the skateboard.

1 . A protector for axle threads on a skateboard and a bearing of a wheel on the threaded skateboard axle, comprising: 
 a nut section having a top, a bottom, and a central axis, said nut section adapted to threadably engage the axle of the skateboard;    a flange coupled to said nut section adjacent said bottom, said flange extending outwardly from said bottom in a direction generally perpendicular to said central axis, said flange sized and adapted to cover and protect the adjacent skateboard wheel bearing;    a locking ring coupled to said nut section; and    a metal cap coupled to said locking ring; whereby the threaded axle of a skateboard truck is protected from abrasion by said metal cap and the bearing of the wheel upon the threaded axle is protected from debris and damage by said flange.

       3 . A protector for axle threads on a skateboard and a bearing of a wheel on the threaded skateboard axle as set forth in  claim 2 , wherein said metal cap further comprises: 
 a crown; and    a circumscribing flange; whereby    a top of said cage section entraps said circumscribing flange of said metal cap between said top cage section and said locking ring.    
   
   
       4 . A protector for axle threads on a skateboard and a bearing of a wheel on the threaded skateboard axle as set forth in  claim 1 , wherein said locking ring further comprises: 
 resilient material into which the axle threads may cut or pass.    
   
   
       5 . A protector for axle threads on a skateboard and a bearing of a wheel on the threaded skateboard axle as set forth in  claim 1 , further comprising: 
 a shield through which the threaded skateboard axle may pass, said shield adapted to cover and protect an inside bearing of the skateboard wheel while said flange coupled to said nut section protects an outer bearing of the same skateboard wheel.    
   
   
       6 . A protector for skateboard axle threads on a skateboard axle having a skateboard wheel with an accompanying bearing, comprising: 
 a nut section having a top, a bottom, and a central axis, said nut section adapted to threadably engage the skateboard axle;    a flange coupled to said nut section adjacent said bottom, said flange extending outwardly from said bottom in a direction generally perpendicular to said central axis, said flange sized and adapted to cover and protect the skateboard wheel bearing present on the skateboard axle;    a locking ring coupled to said nut section, said locking ring constructed of resilient material into which threads of the skateboard axle may cut or pass, said locking ring serving to retain itself and said nut section upon the skateboard axle;    a metal cap coupled to said locking ring, said metal cap having a crown and a circumscribing flange; and    a cage section coupled to said top of said nut section, said cage section entrapping said metal cap and said locking ring between an upper part of said cage section and said top of said nut section, said cage section entrapping said circumscribing flange of said metal cap between said top cage section and said locking ring; whereby    a threaded skateboard axle of a skateboard truck is protected from abrasion by said metal cap and a bearing of wheel upon said threaded axle is protected from debris by said flange.    
   
   
       7 . A protector for skateboard axle threads on a skateboard axle having a skateboard wheel with an accompanying bearing as set forth in  claim 6 , further comprising: 
 a shield through which the skateboard axle may pass, said shield adapted to cover and protect an inside bearing of the skateboard wheel while said flange coupled to said nut section protects an outer bearing of the same skateboard wheel.    
   
   
       8 . A skateboard truck, comprising: 
 A threaded axle;    A skateboard wheel having a first bearing rotating upon said threaded axle;    a nut section having a top, a bottom, and a central axis, said nut section adapted to threadably engage said threaded axle;    a flange coupled to said nut section adjacent said bottom, said flange extending outwardly from said bottom in a direction generally perpendicular to said central axis, said flange sized and adapted to cover and protect said first bearing;    a locking ring coupled to said nut section; and    a metal cap coupled to said locking ring; whereby    said threaded axle of a skateboard truck is protected from abrasion by said metal cap and said first bearing of said skateboard wheel is protected from debris by said flange.    
   
   
       9 . A skateboard truck as set forth in  claim 8 , further comprising: 
 a cage section coupled to said top of said nut section, said cage section entrapping said metal cap and said locking ring between an upper part of said cage section and said top of said nut section.    
   
   
       10 . A skateboard truck as set forth in  claim 9 , wherein said metal cap further comprises: 
 a crown; and    a circumscribing flange; whereby    a top of said cage section entraps said circumscribing flange of said metal cap between said top cage section and said locking ring.    
   
   
       11 . A skateboard truck as set forth in  claim 8 , wherein said locking ring further comprises: 
 resilient material into which threads of said threaded axle may cut or pass.    
   
   
       12 . A skateboard truck as set forth in  claim 8 , further comprising: 
 a shield through which said threaded axle passes, said shield adapted to cover and protect an inside of a second bearing of said skateboard wheel while said flange coupled to said nut section protects an outside of said first bearing of the same skateboard wheel.    
   
   
       13 . A skateboard truck as set forth in  claim 12 , further comprising: 
 said first and second bearing being the same bearing.    
   
   
       14 . A skateboard truck, comprising: 
 A threaded axle;    A skateboard wheel having a first bearing rotating upon said threaded axle;    a nut section having a top, a bottom, and a central axis, said nut section adapted to threadably engage said threaded axle;    a flange coupled to said nut section adjacent said bottom, said flange extending outwardly from said bottom in a direction generally perpendicular to said central axis, said flange sized and adapted to cover and protect said first bearing;    a locking ring coupled to said nut section, said locking ring constructed of resilient material into which threads of said threaded axle may cut or pass, said locking ring serving to retain itself and said nut section upon said threaded axle;    a metal cap coupled to said locking ring, said metal cap having a crown and a circumscribing flange; and    a cage section coupled to said top of said nut section, said cage section entrapping said metal cap and said locking ring between an upper part of said cage section and said top of said nut section, said cage section entrapping said circumscribing flange of said metal cap between said top cage section and said locking ring; whereby    said threaded axle of a skateboard truck is protected from abrasion by said metal cap and said first bearing of said skateboard wheel is protected from debris by said flange.    
   
   
       15 . A skateboard truck as set forth in  claim 14 , further comprising: 
 a shield through which said threaded axle passes, said shield adapted to cover and protect an inside of a second bearing of said skateboard wheel while said flange coupled to said nut section protects an outside of said first bearing of the same skateboard wheel.    
   
   
       16 . A skateboard truck as set forth in  claim 15 , further comprising:
