Beveling wheel, method for forming a beveled lens for use with eyeglasses and a beveled lens

Abstract

The present invention relates to a beveling wheel and method for forming a beveled lens with the beveling wheel for use with eyeglasses. One embodiment includes a prescription lens for use on an eyeglass frame having a receiving channel. The receiving channel includes a channel bottom and opposed interior wall surfaces having a first angle therebetween. The prescription plastic lens includes a prescription lens body generally defined by a peripheral edge having a bevel extending away from the edge to a vertex. The bevel has a distal portion with a second angle. The bevel is receivable within the receiving channel. At least a portion of the vertex of the bevel has an interference fit with the receiving channel bottom when held within the eyeglass frame. The first angle is greater than the second angle.

         11 . A beveling wheel for use in forming a bevel on a plastic lens for an eyeglass frame having a receiving channel, the bevel having a vertex, the receiving channel being defined by opposed interior wall surfaces having a first angle therebetween at a channel bottom disposed at one end, the beveling wheel comprising:
 an annular disk having a periphery and a central axis; and   a bevel groove for use in forming the bevel, the bevel groove disposed on the periphery of the annular disk, the bevel groove having a distal end disposed between the periphery and the central axis, the distal end comprising a second angle less than the first angle such that the vertex contacts the channel bottom.   
     
     
         12 . The beveling wheel of  claim 11 , wherein the annular disk's periphery includes an abrasive layer, the depth of the bevel groove relative to the abrasive layer adjacent to the beveling groove ranges from 0.25 mm to 1.1 mm. 
     
     
         13 . The beveling wheel of  claim 11 , wherein the depth of the bevel groove relative to the periphery ranges from 0.4 mm to 1 mm. 
     
     
         14 . The beveling wheel of  claim 11 , wherein the second angle ranges from 100 degrees to 130 degrees. 
     
     
         15 . The beveling wheel of  claim 11 , wherein the second angle ranges from 105 degrees to 118 degrees. 
     
     
         16 . An eyeglasses component, comprising:
 an eyeglasses frame;   two plastic lenses supported by the eyeglasses frame, the lenses being formed using the beveling wheel of  claim 11 .   
     
     
         17 . The beveling wheel of  claim 11 , wherein the annular disk comprising at least two beveling wheel portions, the first beveling wheel portion including a first annular surface, a first periphery, and a first abrasive layer disposed on the first periphery and having a first inwardly directed surface at a first angle, the second beveling wheel portion including a second annular surface, a second periphery and second abrasive layer disposed on the second periphery and having a second inwardly directed surface at a second angle, the first annular surface contacting the second annular surface with the first and second inwardly directed surfaces defining the bevel groove. 
     
     
         18 - 22 . (canceled) 
     
     
         23 . A beveling wheel for use in forming a bevel on a plastic lens, the beveling wheel comprising:
 an annular disk having a periphery and a central axis; and   a bevel groove disposed on the periphery of the annular disk, the bevel groove having a distal end disposed between the periphery and the central axis, the distal end comprising an angle ranging from 108 degrees to 118 degrees.   
     
     
         24 . The beveling wheel of  claim 23 , wherein the bevel groove has a height ranging from 0.28 mm to 1 mm.
