Skate wheels incorporating transverse-mounted and self-powered illuminating devices

Abstract

An in-line skate wheel incorporating transverse-mounted and self-powered illuminating device is disclosed. The wheel includes two mutually coupled anchors, a rotor held between the two coupled anchors, multiple illuminating devices installed in transverse orientation on the rotor, a stator within the rotor but kept apart from the rotor, an axle extending through the two coupled anchors and the stator, and a protective covering placed around the rim of the first and second anchors. The transverse-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 to avoid abrasion on the surface of the illuminating devices that would otherwise attenuate the light given out by the illuminating devices.

1 . An in-line skate wheel incorporating transverse-mounted and self-powered illuminating device, comprising: 
 two mutually coupled first and second anchors, with the second anchor having a recessed portion on the side facing the first anchor, such that when the two anchors are joined together a chamber is defined in between walls of the two anchors;    a ring-shaped rotor being placed in the chamber, wherein the rotor is formed by-a ring-shaped induction coil and two metal plates; 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 therebetween, wherein a first end of the induction coil is connected to the coupled metal plates; whereby the rotor is able to revolve synchronously revolution of the two coupled anchors,    multiple illuminating devices being inserted on the rotor and in transverse orientation, wherein each illuminating device has a first terminal and a second terminal, the first terminal being electrically fixed on one of the two metal plates, the second terminal being 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 the stator; a protective covering, made of translucent materials, being placed around the circumference of the two coupled anchors;    wherein multiple gaps are defined in the two metal plates and corresponding to the positions of the illuminating devices for accommodating the illuminating devices, such that the terminals of the installed illuminating devices do not touch the metal plates; and    multiple open slots are formed on the second anchor corresponding to the positions of the illuminating devices for receiving the illuminating devices to be installed on the rotor through the second anchor.    
   
   
       2 . The in-line skate wheel as claimed in  claim 1 , wherein the illuminating device is a light emitting diode (LED) that has two terminals respectively connected to the two metal plates over the rotor.  
   
   
       3 . The in-line skate wheel as claimed in  claim 1 , wherein two bearing sleeves are fitted into respective notches on the outer wall of the two coupled anchors to receive the axle.  
   
   
       4 . The in-line skate wheel as claimed in  claim 1 , wherein the two metal plates are joined together by welding.  
   
   
       5 . The in-line skate wheel as claimed in  claim 2 , wherein the two metal plates are joined together by welding.
