Buckle having easy separation operation

Abstract

A buckle includes a male buckle member and a female buckle member. The male buckle member has: a male buckle body having a first coupler at a first end; a guide formed at a second end of the male buckle body and having a first guide surface; and an elastic arm formed at the second end of the male buckle body at a predetermined distance from the guide, being bendable toward the guide, and having a projection and a second guide surface. The female buckle member has: a female buckle body having a second coupler at a first end; a housing formed at a second end of the female buckle body and having a space for receiving the guide and the elastic arm; and a side hole formed to secure the projection of the elastic arm when the guide and the elastic arm are inserted in the space.

What is claimed is: 
     
         1 . A buckle having easy separation operation, the buckle comprising: a male buckle member and a female buckle member,
 wherein the male buckle member has:   a male buckle body having a first coupler at a first end;   a guide formed at a first side of a second end of the male buckle body and having a first guide surface on an outer side; and   an elastic arm formed at a second side of the second end of the male buckle body at a predetermined distance from the guide, having flexibility to be bent toward the guide by force from the outside, and having a projection on an outer side and a second guide surface formed on an outer side of the projection and inclined inward, and   the female buckle member has:   a female buckle body having a second coupler at a first end;   a housing formed at a second end of the female buckle body and having a space for receiving the guide and the elastic arm; and   a side hole formed through a side of the housing and securing the projection of the elastic arm such that the projection is exposed to the outside when the guide and the elastic arm are inserted in the space.   
     
     
         2 . The buckle of  claim 1 , wherein the first guide surface is inclined toward the elastic arm. 
     
     
         3 . The buckle of  claim 1 , wherein the second guide surface is inclined toward the guide. 
     
     
         4 . The buckle of  claim 1 , wherein a pair of first guide protrusions is formed with a first guide groove therebetween on each of a top and a bottom of the guide, and
 a pair of second guide grooves corresponding to the first guide protrusions is formed with a second guide protrusion corresponding to the first guide groove therebetween on each of upper and lower inner sides of the housing.   
     
     
         5 . The buckle of  claim 1 , wherein the first coupler has a pair of first coupler holes formed in a line at both sides of the first end of the male buckle body. 
     
     
         6 . The buckle of  claim 1 , wherein the second coupler has a pair of second coupler holes formed in a line at both sides of the first end of the female buckle body.
