Release buckle

Abstract

The present invention relates to a release buckle for coupling or decoupling a band used in a bag, a sack, clothing and the like for carrying articles, which includes a fixing base formed with protrusion parts on both sides of a front surface thereof with fitting hook guide coupling grooves, and a fitting hook inserted into a lower part of the fixing base to be positioned in the fixing base entirely, wherein the releasing work for releasing the holding state of the fitting hook by using fingers, which has been carried out in the prior art release buckle in advance to separate the fitting hook from the fixing base, is not necessary any more, especially, it becomes possible to couple or decouple the fitting hook with or from the fixing base conveniently while wearing thick gloves in winter time, the coupling state between the fitting hook and the fixing base may be kept more stably, and an entire area of the release buckle in the coupled state may be reduced, creating compact and clean images.

1 . A release buckle comprising:
 a fixing base formed with protrusion parts on both sides of a front surface thereof, the protrusion parts having fitting hook guide coupling grooves provided with inlets at lower parts; and   a fitting hook formed with at least one or more band connection holes for connecting a band, inserted into a lower part of the fixing base to be positioned in the fixing base entirely, and having both side ends detachably coupled in the guide coupling grooves of the protrusion parts of the fixing base.   
   
   
       2 . The release buckle as claimed in  claim 1 , wherein the fitting hook is formed with a handle protrusion at an upper end of a front part, so that the fitting hook is moved by holding the handle protrusion. 
   
   
       3 . The release buckle as claimed in  claim 1 , wherein the fitting hook is formed with two band connection holes for controlling a connection length of the band freely. 
   
   
       4 . The release buckle as claimed in  claim 2 , wherein the fitting hook is formed with two band connection holes for controlling a connection length of the band freely. 
   
   
       5 . The release buckle as claimed in  claim 1 , wherein the fixing base is provided with a joining flange at an outer periphery and the joining flange is formed with a sewing groove to mount the fixing base to a surface of an article by sewing. 
   
   
       6 . The release buckle as claimed in  claim 2 , wherein the fixing base is provided with a joining flange at an outer periphery and the joining flange is formed with a sewing groove to mount the fixing base to a surface of an article by sewing. 
   
   
       7 . The release buckle as claimed in  claim 3 , wherein the fixing base is provided with a joining flange at an outer periphery and the joining flange is formed with a sewing groove to mount the fixing base to a surface of an article by sewing. 
   
   
       8 . The release buckle as claimed in  claim 1 , wherein the fixing base is formed with a band connection hole in the center of the lower part so as to connect a connection band sewed on a surface of a connected article into the band connection hole. 
   
   
       9 . The release buckle as claimed in  claim 2 , wherein the fixing base is formed with a band connection hole in the center of the lower part so as to connect a connection band sewed on a surface of a connected article into the band connection hole. 
   
   
       10 . The release buckle as claimed in  claim 3 , wherein the fixing base is formed with a band connection hole in the center of the lower part so as to connect a connection band sewed on a surface of a connected article into the band connection hole. 
   
   
       11 . The release buckle as claimed in  claim 1 , wherein the fixing base is provided with a rectangular opening in the center of an upper part thereof and the opening is provided with a holding protrusion part, so that the band coupled with the fitting hook passes beyond the holding protrusion part and captured and supported by the holding protrusion part for keeping coupling state between the fitting hook and the fixing base stably when coupling the fitting hook with the fixing base. 
   
   
       12 . The release buckle as claimed in  claim 2 , wherein the fixing base is provided with a rectangular opening in the center of an upper part thereof and the opening is provided with a holding protrusion part, so that the band coupled with the fitting hook passes beyond the holding protrusion part and captured and supported by the holding protrusion part for keeping coupling state between the fitting hook and the fixing base stably when coupling the fitting hook with the fixing base. 
   
   
       13 . The release buckle as claimed in  claim 3 , wherein the fixing base is provided with a rectangular opening in the center of an upper part thereof and the opening is provided with a holding protrusion part, so that the band coupled with the fitting hook passes beyond the holding protrusion part and captured and supported by the holding protrusion part for keeping coupling state between the fitting hook and the fixing base stably when coupling the fitting hook with the fixing base. 
   
   
       14 . The release buckle as claimed in  claim 5 , wherein the fixing base is provided with a rectangular opening in the center of an upper part thereof and the opening is provided with a holding protrusion part, so that the band coupled with the fitting hook passes beyond the holding protrusion part and captured and supported by the holding protrusion part for keeping coupling state between the fitting hook and the fixing base stably when coupling the fitting hook with the fixing base. 
   
   
       15 . The release buckle as claimed in  claim 8 , wherein the fixing base is provided with a rectangular opening in the center of an upper part thereof and the opening is provided with a holding protrusion part, so that the band coupled with the fitting hook passes beyond the holding protrusion part and captured and supported by the holding protrusion part for keeping coupling state between the fitting hook and the fixing base stably when coupling the fitting hook with the fixing base. 
   
   
       16 . The release buckle as claimed in  claim 1 , wherein the fixing base is formed with band connection holes at both side ends to connect a vertical band and another band connection hole in the center to connect a horizontal band. 
   
   
       17 . The release buckle as claimed in  claim 2 , wherein the fixing base is formed with band connection holes at both side ends to connect a vertical band and another band connection hole in the center to connect a horizontal band. 
   
   
       18 . The release buckle as claimed in  claim 16 , wherein the fixing base is formed with a holding protrusion in the center of a front lower part and the fitting hook is formed with a holding groove corresponding to the holding protrusion in the center of a rear lower part, so that the holding protrusion of the fixing base is coupled in the holding groove of the fitting hook to keep the coupling state between the fitting hook and the fixing base stably when coupling the fitting hook with the fixing base.
