Buckle

Abstract

A buckle includes: a plug member which includes support arms formed at both ends in a forward direction of a base, and a support part formed forward from the base between the two support arms; a socket member that includes support chambers formed at both ends where the support arms are inserted, a central chamber formed between the two support chambers and having an open front, a retained part formed at the rear end of the central chamber, and a first magnet embedded inside the central chamber; and a locking member which is rotatably mounted on the support part, and includes a second magnet embedded in the center to correspond with the first magnet when the plug member and the socket member are coupled.

1 . A buckle comprising:
 a plug member which includes support arms formed at both ends in a forward direction of a base, and a support part formed forward from the base between the two support arms;   a socket member that includes support chambers formed at both ends where the support arms are inserted, a central chamber formed between the two support chambers and having an open front, a retained part formed at the rear end of the central chamber, and a first magnet embedded inside the central chamber; and   a locking member which is rotatably mounted on the support part, and includes a hook part formed at the front end thereof to be coupled to the retained part when the plug member and the socket member are coupled, and a second magnet embedded in the center to correspond with the first magnet when the plug member and the socket member are coupled.   
     
     
         2 . The buckle according to  claim 1 , wherein an inclined guide part is formed on the bottom surface of the central chamber to guide the entry of the locking member. 
     
     
         3 . The buckle according to  claim 1 , wherein an inclined protrusion is formed at the rear end of the bottom surface of the central chamber to guide the entry and coupling of the locking member. 
     
     
         4 . The buckle according to  claim 1 , wherein slots are formed on both sides of the central chamber, and coupling protrusions which match the slots are formed on both sides of the locking member. 
     
     
         5 . The buckle according to  claim 1 , wherein a narrowed protrusion is further formed on the rear surface of the base to narrow the front end of the socket member when the socket member is coupled. 
     
     
         6 . The buckle according to  claim 1 , wherein a groove for connecting a string is further formed at the front end of the locking member. 
     
     
         7 . The buckle according to  claim 1 , wherein hinge grooves are formed on both sides of the support part, a hinge is provided, and connection parts are formed on both sides of the rear end of the locking member to be assembled with the hinge within the hinge grooves. 
     
     
         8 . The buckle according to  claim 7 , wherein partitions which partition the support chambers and the central chamber are inserted into the hinge grooves during coupling with the plug member to be in close contact with the connection parts of the locking member. 
     
     
         9 . The buckle according to  claim 1 , wherein a cross bar and a strap bar for connecting a strap are selectively formed on one side of the body of the plug member or the socket member. 
     
     
         10 . The buckle according to  claim 1 , wherein a connecting member selected from a ring, a clip, a loop, a binding buckle, and a strap connector is integrally formed on one side of the body of the plug member or the socket member.
