Skate wheel having skew-mounted and self-powered illuminating devices

Abstract

An in-line skate wheel having skew-mounted and self-powered illuminating devices is disclosed. The wheel includes a first and a second anchor joined together creating a chamber in the middle, a rotor held in the chamber, multiple illuminating devices inserted with a skew angle on the rotor, a stator fitted in the rotor, an axle passing through the two coupled anchors and the stator, and a protective covering placed around the rim of the two anchors. The skew-mounted illuminating devices allow the skate wheel to be fitted on in-line skates and skate boards that can only use small wheels. Further, the present design can prevent scratching of the illuminating devices against the ground that would otherwise cause abrasion on the surface of the illuminating devices and attenuate the light given out by the illuminating devices.

1 . A skate wheel having skew-mounted and self-powered illuminating devices, comprising: 
 two mutually coupled anchors, each having a recessed portion on one side facing each other, such that when the two anchors are joined together the two recessed portions are combined to produce a chamber in between the two anchors;    a ring-shaped rotor being placed in the above chamber defined by the two coupled anchors, wherein the rotor is formed by a ring-shaped induction coil and two metal plates, wherein the induction coil is formed by a wire wound around a circular core, and the two metal plates are joined together holding the induction coil in between, where a first end of the induction coil connected to the coupled metal plates; whereby the rotor is able to revolve synchronously with revolution of the coupled anchors;    multiple illuminating devices being installed with a skew angle on the rotor, wherein each illuminating device has a first terminal and a second terminal, the first terminal is connected to the two metal plates, and the second terminal is connected to a second end of the induction coil;    a stator being fitted in the rotor, but not in physical contact with the rotor;    an axle extending through the two coupled anchors and secured with the stator;    a protective covering formed around the circumference of the two anchors; wherein    multiple pairs of one of the projected portions and one of the sunken portions are formed on the rim of the two anchors, where each pair of the projected portion and the sunken portion, when the two anchors are mutually coupled, creates a volume on the rim of the rotor that is inclined at an angle that corresponds with the skew angle of each corresponding illuminating device.    
   
   
       2 . The skate wheel as claimed in  claim 1 , wherein each illuminating device is inserted into the volume with a skew angle of 45 degrees in relation to the rotor positioned in an upright direction.  
   
   
       3 . The skate wheel as claimed in  claim 2 , wherein each illuminating device is a light emitting diode (LED) having two terminals respectively connected to the two metal plates of the rotor.  
   
   
       4 . The skate wheel as claimed in  claim 1 , wherein two bearing sleeves are fitted into respective notches on the outer wall of the two anchors to receive the axle.  
   
   
       5 . The skate wheel as claimed in  claim 1 , wherein the two metal plates are joined together by welding.  
   
   
       6 . The skate wheel as claimed in  claim 2 , wherein the two metal plates are joined together by welding.  
   
   
       7 . The skate wheel as claimed in  claim 3 , wherein the two metal plates are joined together by welding.  
   
   
       8 . The skate wheel as claimed in  claim 4 , wherein the two metal plates are joined together by welding.
