Spinner key ring with locking interchangeable parts

Abstract

A spinner key ring with locking interchangeable parts is provided. The locking system consists of a set pin and a locking screw or pin that locks the center piece to the outer ring. The spinner key ring has an outer metal ring with a loop called the earpiece at the top, which connects to a chain and then to a split ring to hold keys. The earpiece itself is drilled through the middle to allow the screw to go through the outer ring and into the centerpiece. The length of the screw is 5 millimeters. On the opposite side of the outer ring from the earpiece is a 3-millimeter fixed pin, which the center piece seats onto. Once the centerpiece is seated, the screw is inserted through the earpiece. Using this system the centerpiece is locked into place and is also interchangeable. The system can be used with any shaped outer ring.

What is claimed is:  
     
         1 . An assembly system for spinner key rings with lockable interchanging parts: 
 a screw inserted through the ear piece of an outer metal ring into the centerpiece, with a fixed stem connected to the outer ring on the opposite side, creates a lockable assembly that is also interchangeable by unscrewing the screw from the ear piece and raising the centerpiece to remove off the fixed pin below, then a new center can be inserted and locked.    
     
     
         2 . An assembly system for spinner key rings with lockable interchanging parts according to  claim 1  results in an unbreakable key ring.  
     
     
         3 . An assembly system for spinner key rings with lockable interchanging parts according to  claim 1  results in a key ring that can change by removing the centerpiece.
