Pair of nail clippers

Abstract

The nail clippers are designed for bringing one cutting edge formed on a tip of the one cutting blade closer to the other cutting edge, the one cutting edge and the other cutting edge being disposed facing opposite each other and holding a particular nail being to be cut between the two opposed cutting edges to cause the two opposed cutting edges to engage each other and cut that particular nail. The one cutting edge and the other cutting edge have, respective straight line portions which face opposite each other and extend parallel to each other and respective curved portions which are provided contiguously to the corresponding straight line portions and which are curved and extended at a curvature that permits the one curved portion to exactly match the other curved portion when they meet each other.

1 . A pair of nail clippers which comprise two cutting blades facing opposite each other, one of the two cutting blades having a cutting edge formed on a tip of the one cutting edge and the other of the two opposed cutting blades having a cutting edge formed on a tip of the other cutting blade, and are designed for cutting the nails on the human fingers and toes by bringing the two opposed cutting edges closer to each other, holding a particular nail being to be cut between the two opposed cutting edges thus brought closer to each other and thereby causing the two opposed cutting edges to engage each other, wherein the cutting edge of the one cutting blade and the cutting edge of the other cutting blade include:
 respective straight line portions that are provided to face opposite each other and extend parallel to each other in a direction perpendicular to the direction in which the two opposed cutting edges are moved closer to each other and   respective curved portions that are provided to be contiguous to the above corresponding straight line portions and to be curved and extended at a curvature that permits the one cutting edge to exactly match the other cutting edge when they meet each other.   
     
     
         2 . A pair of nail clippers as defined in  claim 1 , wherein said curved portion is formed on both sides of each corresponding one of said straight line portions in the direction in which each corresponding one of said straight line portions extends. 
     
     
         3 . A pair of nail clippers as defined in  claim 1 , wherein each of said curved portions is only formed on one side of each corresponding one of said straight line portions in the direction in which each corresponding one of said straight line portions extends. 
     
     
         4 . A pair of nail clippers as defined in  claim 1 , wherein the one cutting blade and the other cutting blade facing opposite each other are provided separately from each other by cutting a single place into two separate parts along the center line thereof, the one part of which provides one cutting edge portion and the other part of which provides the other cutting edge portion, the one cutting edge portion having a tip edge so formed as to face opposite the other cutting edge portion and which serves as the one cutting edge and the other cutting edge portion having a tip edge so formed as to face opposite the one cutting edge portion and which serves as the other cutting edge or vice versa. 
     
     
         5 . A pair of nail clippers as defined in  claim 4 , further including one pair of cutting edge supporting members that are provided so that they can be moved closer to or farther away from each other and wherein the one cutting blade and the other cutting blade can be attached to or detached from the tips of the corresponding cutting edge supporting members, respectively. 
     
     
         6 . A pair of nail clippers as defined in  claim 2 , wherein the one cutting blade and the other cutting blade facing opposite each other are provided separately from each other by cutting a single place into two separate parts along the center line thereof, the one part of which provides one cutting edge portion and the other part of which provides the other cutting edge portion, the one cutting edge portion having a tip edge so formed as to face opposite the other cutting edge portion and which serves as the one cutting edge and the other cutting edge portion having a tip edge so formed as to face opposite the one cutting edge portion and which serves as the other cutting edge or vice versa. 
     
     
         7 . A pair of nail clippers as defined in  claim 6 , further including one pair of cutting edge supporting members that are provided so that they can be moved closer to or farther away from each other and wherein the one cutting blade and the other cutting blade can be attached to or detached from the tips of the corresponding cutting edge supporting members, respectively.
