Definitions
- the present invention relates to a method of manufacturing arc type blades for a nail clipper and arc type blades and a nail clipper, and in particular, a method of manufacturing arc type blades for a nail clipper, which correspond to a curved surface of a finger nail, and arc type blades and a nail clipper manufactured by the same.
- An arc type nail clipper has the characteristic in that blades are arc in shape from a front view, so as to correspond to a curved surface of a finger nail. Accordingly, upon cutting a finger nail by using the arc type nail clipper, no uncomfortable feeling is caused by the pressure first applied to both side ends of the finger nail or the finger nail is prevented from being broken. Since the arc type blades are considered as being very important when actually using the arc type nail clipper, a number of patent applications thereof have been filed thirty years ago. Nevertheless, the arc type blades are of an ideal idea only because these have not been realized as a product. That is, due to a problem in manufacturing, the arc type blades have not been commercialized or practically used.
- top and bottom edges are extended from the top and bottom blade bodies, so as to be in contact with each other.
- Each of the top and bottom edges is formed to be inclined in shape and has a little curved surface in external appearance.
- top and bottom edges are simultaneously grinded to be sharpened, by using a grinding roller of a diameter corresponding to the curved surface. Then, when the diameter of the curved surface at the end of the edge is same as the diameter of the grinding roller, the top and bottom edges are generally to be horizontally parallel to each other, in a front view.
- a middle part of the concave arc type edge needs to be formed to be inward curved in an arc shape
- a middle part of the bottom edge needs to be formed to be outward curved in an arc shape, so that the line of the top and bottom blades being in contact with each other is accurately in contact, to clearly cut a finger nail.
- top and bottom edges of a nail clipper The most important basic requirement for manufacturing arc type top and bottom edges of a nail clipper is to form the top and bottom edges which are accurately in contact with each other, by sufficiently allowing variation of a grinding depth of the top and bottom edges and simultaneously grinding the top and bottom edges.
- the edges of the nail clipper are manually, semi-automatically or full- automatically grinded, using a grinding roller of a diameter corresponding to a diameter of a curved surface of an edge end.
- Manual grinding makes a big difference in a grinding result, depending on the extent of skill of an operator.
- Semi-automatic and automatic grinding generates deviation, depending on the dimension variation of a fixing unit for fixing the nail clipper, the variation of a transfer unit for automation and the extent of abrasion of a grinding belt.
- the arc type nail clipper in which the curves of concave and convex arc type edges are accurately in contact with each other is manufactured by a method of manufacturing arc type blades for the nail clipper, which 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
- 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
- the arc type nail clipper in which the curves of concave and convex arc type edges are accurately in contact with each other is manufactured by a method of manufacturing arc type blades for the nail clipper, which 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 incline, and forming an end of the top blade so as to be a
- the edge of a top blade and edge of a bottom blade are simultaneously grinded in one vertical plane while these are in contact with each other, so that an concave arc type edge in an arc shape is formed at the end of the top blade and an convex arc type edge in an arc shape is formed on the end of the bottom blade, thereby manufacturing arc type edges of an arc type nail clipper in which the concave and convex arc type edges are accurately in contact with each other.
