Abstract

A magnetic clasp for securing a piece of jewelry that includes a first connecting device having a first cylindrical magnet with a top surface. The first cylindrical magnet has a hollow cylindrical section located at the center of the first top surface. Additionally, a second connecting device has a second cylindrical magnet with a second top surface. The second cylindrical magnet has a cylindrical protruding member located at the center of the second top surface. The protruding section of the second connecting device fits into the hollow section of the first connecting device. The magnetic clasp locks when the first and second connecting devices are brought together allowing opposite magnetic poles to face each other. To unlock the magnetic clasp the first and second connecting devices are rotatably turned allowing like poles to face each other.

Claims

exact text as granted — not AI-modified
1 . A magnetic clasp for securing a piece of jewelry, comprising: 
 first connecting means including a first magnet having a first top surface, said first magnet having a hollow section located in the center of said first top surface, and said first top surface being divided into at least two opposite magnetic poles; and    second connecting means including a second magnet having a second top surface, said second magnet having a protruding member located in the center of said second top surface, said second top surface being divided into at least two opposite magnetic poles, and wherein said protruding member of said second connecting means fits into said hollow section of said first connecting means.    
   
   
       2 . The magnetic clasp as claimed in  claim 1 , further comprising: 
 locking means for connecting said first and second connecting means together, wherein said protruding member is aligned with said hollow section allowing the opposite magnetic poles of the first and second top surfaces to face each other, thereby locking the first and second connecting means together.    
   
   
       3 . The magnetic clasp as claimed in  claim 2 , further comprising: 
 unlocking means for disconnecting said first and second connecting means, wherein said first and second connecting means are rotatably turned allowing like magnetic poles on the first and second top surfaces to face each other, thereby forcing the first and second connecting means away from each other.    
   
   
       4 . The magnetic clasp as claimed in  claim 1  wherein said first top surface and said second top surface are flat.  
   
   
       5 . The magnetic clasp as claimed in  claim 1  wherein the first top surface is concave and the second top surface is convex.
