Manufacturing Method For Arc Type Nail Clipper Blade, and Its Nail Clipper Blade and Its Nail Clipper

Abstract

The present invention relates to a method of manufacturing arc type blades for a nail clipper, which corresponds to a curved surface of a finger nail, arc type blades and a nail clipper manufactured by the same. The method of manufacturing arc type blades for an nail clipper, comprises: forming a top blade and a bottom blade forming a blade body, so as to incline at a same inclination angle, so that one end of the top blade is connected to one end of the bottom blade; forming an inner surface of a downward incline of the top blade so as to be inward curved in an arc shape which has a predetermined curvature and is extended along the downward incline, and forming an end of the top blade so as to be a vertical plane for forming an edge; forming an inner surface of an upward incline of the bottom blade so as to be outward curved in an arc shape which has the same curvature as that of the arc shape in the top blade and which is extended along the upward incline, and an end of the bottom blade so as to be a vertical plane for forming an edge; allowing the two ends of the top and bottom blades to be in contact with each other and grinding the two ends simultaneously in the vertical plane, to form the edge which is inward curved in the arc shape at the end of the top blade and the edge which is outward curved in the arc shape at the end of the bottom blade, thereby forming the arc type nail clipper in which the curves of the concave and convex arc type edges are accurately in contact with each other.

1 . A method of manufacturing arc type blades for an nail clipper, comprising:
 forming a top blade and a bottom blade forming a blade body, so as to incline at a same inclination angle, so that one end of the top blade is connected to one end of the bottom blade;   forming an inner surface of a downward incline of the top blade so as to be inward curved in an arc shape which has a predetermined curvature and is extended along the downward incline, and forming an end of the top blade so as to be a vertical plane for forming an edge;   forming an inner surface of an upward incline of the bottom blade so as to be outward curved in an arc shape which has the same curvature as that of the arc shape in the top blade and which is extended along the upward incline, and an end of the bottom blade so as to be a vertical plane for forming an edge;   allowing the two ends of the top and bottom blades to be in contact with each other and grinding the two ends simultaneously in the vertical plane, to form the edge which is inward curved in the arc shape at the end of the top blade and the edge which is outward curved in the arc shape at the end of the bottom blade.   
   
   
       2 . Arc type blades for a nail clipper, comprising:
 a top blade and a bottom blade forming a blade body, which are formed so as to incline at a same inclination angle, so that one end of the top blade is connected to one end of the bottom blade;   a downward incline of the top blade, the downward incline with an inner surface formed so as to be inward curved in an arc shape which has a predetermined curvature and is extended along the downward incline;   an end of the top blade, the end formed so as to be a vertical plane, for forming an edge;   an upward incline of the bottom blade, the upward incline with an inner surface formed so as to be outward curved in an arc shape which has the same curvature as that of the arc shape in the top blade and which is extended along the upward incline; and   an end of the bottom blade, the end formed so as to be a vertical plane for forming an edge, and   wherein the two ends of the top and bottom blades are in contact with each other to be grinded simultaneously in the vertical plane, to form the edge which is inward curved in the arc shape at the end of the top blade and the edge which is outward curved in the arc shape at the end of the bottom blade.   
   
   
       3 . The arc type blades of  claim 2 , wherein the top blade and the bottom blade are connected as one body, by rivet-welding or spot-welding the other end of the top blade and the other end of the bottom blade. 
   
   
       4 . The arc type blades of  claim 2 , wherein the top blade and the bottom blade are formed in one body as the other end of the top blade and the other end of the bottom blade are formed to be bent. 
   
   
       5 . An arc type nail clipper which comprises a blade body, and a lever formed by a supporting shaft through a supporting shaft hole formed in the blade body, comprising:
 a top blade and a bottom blade forming the blade body, which are formed so as to incline at a same inclination angle, so that one end of the top blade is connected to one end of the bottom blade;   a downward incline of the top blade, the downward incline with an inner surface formed so as to be inward curved in an arc shape which has a predetermined curvature and is extended along the downward incline;   an end of the top blade, the end formed so as to be a vertical plane, for forming an edge;   an upward incline of the bottom blade, the upward incline with an inner surface formed so as to be outward curved in an arc shape which has the same curvature as that of the arc shape in the top blade and which is extended along the upward incline; and   an end of the bottom blade, the end formed so as to be a vertical plane for forming an edge, and   wherein the two ends of the top and bottom blades are in contact with each other to be grinded simultaneously in the vertical plane, to form the edge which is inward curved in the arc shape at the end of the top blade and the edge which is outward curved in the arc shape at the end of the bottom blade.   
   
   
       6 . An arc type nail clipper which comprises a nail clipper body with a supporting shaft hole formed at one side thereof, a blade body with a supporting shaft hole and comprising a top blade and a bottom blade, and a lever positioned on the nail clipper body and connected to the blade body and the nail clipper body by a supporting shaft, for performing a lever function, comprising:
 a top blade and a bottom blade forming the blade body, which are formed so as to incline at a same inclination angle, so that one end of the top blade is connected to one end of the bottom blade;   a downward incline of the top blade, the downward incline with an inner surface formed so as to be inward curved in an arc shape which has a predetermined curvature and is extended along the downward incline;   an end of the top blade, the end formed so as to be a vertical plane, for forming an edge;   an upward incline of the bottom blade, the upward incline with an inner surface formed so as to be outward curved in an arc shape which has the same curvature as that of the arc shape in the top blade and which is extended along the upward incline; and   an end of the bottom blade, the end formed so as to be a vertical plane for forming an edge, and   wherein the two ends of the top and bottom blades are in contact with each other to be grinded simultaneously in the vertical plane, to form the edge which is inward curved in the arc shape at the end of the top blade and the edge which is outward curved in the arc shape at the end of the bottom blade.
