Method and device for coupling spectacles and clip-on sun-shades with each other

Abstract

Disclosed is a method and a device for coupling spectacles and clip-on sun-shades with each other, the spectacles having first lens frames connected together at their inner ends by a first nose frame, lenses fitted into respective first lens frames and arms mounted to outer ends of the first lens frames through hinges, the clip-on sun-shades having second lens frames connected together at their inner ends by a second nose frame and tinted lenses fitted into respective second lens frames. The device comprises a permanent magnet disposed to one of the spectacles and the clip-on sun-shades at a predetermined position; and a soft magnetic member disposed to the other of the spectacles and the clip-on sun-shades at a preset position in a manner such that the soft magnetic member can be mated with the permanent magnet thereby to couple the spectacles and the clip-on sun-shades with each other.

What is claimed is:  
     
         1 . A method for coupling spectacles and clip-on sun-shades with each other, the spectacles having first lens frames connected together at their inner ends by a first nose frame, lenses fitted into respective first lens frames and arms mounted to outer ends of the first lens frames through hinges, the clip-on sun-shades having second lens frames connected together at their inner ends by a second nose frame and tinted lenses fitted into respective second lens frames, the method comprising the steps of: 
 disposing a permanent magnet to one of the spectacles and the clip-on sun-shades at a predetermined position;    disposing a soft magnetic member to the other of the spectacles and the clip-on sun-shades at a preset position in a manner such that the soft magnetic member faces the permanent magnet; and    mating the permanent magnet and the soft magnetic member with each other.    
     
     
         2 . A device for coupling spectacles and clip-on sun-shades with each other, the spectacles having first lens frames connected together at their inner ends by a first nose frame, lenses fitted into respective first lens frames and arms mounted to outer ends of the first lens frames through hinges, the clip-on sun-shades having second lens frames connected together at their inner ends by a second nose frame and tinted lenses fitted into respective second lens frames, the device comprising: 
 a permanent magnet disposed to one of the spectacles and the clip-on sun-shades at a predetermined position; and    a soft magnetic member disposed to the other of the spectacles and the clip-on sun-shades at a preset position in a manner such that the soft magnetic member can be mated with the permanent magnet thereby to couple the spectacles and the clip-on sun-shades with each other.    
     
     
         3 . The device as claimed in    claim 2   , wherein the soft magnetic member disposed to the other of the spectacles and the clip-on sun-shades is formed integrally with a release-preventing piece for preventing the clip-on sun-shades from being uncoupled.  
     
     
         4 . The device as claimed in    claim 2   , wherein contours of the permanent magnet, soft magnetic member and release-preventing piece vary depending upon configurations of the spectacles and the clip-on sun-shades and their positional arrangement.  
     
     
         5 . A device for coupling spectacles and clip-on sun-shades with each other, the spectacles having first lens frames connected together at their inner ends by a first nose frame, lenses fitted into respective first lens frames and arms mounted to outer ends of the first lens frames through hinges, the clip-on sun-shades having second lens frames connected together at their inner ends by a second nose frame and tinted lenses fitted into respective second lens frames, the device comprising: 
 a frontal hinge member  210  of lens frame  102  made of soft magnet,    a corresponding hinge member  220  of sun-shades  150  consisted of one or more extruded plates  202 , 202 , . . . contain(s) permanent magnet  200  in magnet hole  211  to make a closed loop of magnetic flux.    
     
     
         6 . A device for coupling spectacles and clip-on sun-shades with each other, the spectacles having first lens frames connected together at their inner ends by a first nose frame, lenses fitted into respective first lens frames and arms mounted to outer ends of the first lens frames through hinges, the clip-on sun-shades having second lens frames connected together at their inner ends by a second nose frame and tinted lenses fitted into respective second lens frames, the device comprising: 
 a receiving member  300  shaped a piece of tube opend upward and made of soft magnet on the frontal hinge  210 ,    an inserting member  301  of corresponding extruded plate  202  of sun-shades  150  and made of permanent magnet or magnetized itself and extruded downward to be inserted into the receiving member  300 .    
     
     
         7 . A device for coupling spectacles and clip-on sun-shades with each other, the spectacles having first lens frames connected together at their inner ends by a first nose frame, lenses fitted into respective first lens frames and arms mounted to outer ends of the first lens frames through hinges, the clip-on sun-shades having second lens frames connected together at their inner ends by a second nose frame and tinted lenses fitted into respective second lens frames, the device comprising: 
 a receiving extruder  400  of soft magnet, shaped an extruded button upward and has stopper head  401 ,    an inserting member  410  shaped a “hook” and made of permanent magnet to be inserted into the above receiving extrude  400 .    
     
     
         8 . The device as claimed in    claim 5    though    claim 7   , wherein the two corresponding material of soft magnet and permanent magnet can be adopted on the two corresponding members of the receiving members and inserting members selectively.
