Arrow head having ogive

Abstract

A projectile is provided, including an arrowhead body formed of a predetermined length and coupled to a tip of an arrow shaft, and at least two blades protruding at equal intervals from an outer circumferential surface of the arrowhead body, and shaped to be curved to a predetermined direction to result in a rotation by air during a flight of an arrow, in which one or more ogives for reducing air resistance are formed on outer ends of the blades. Accordingly, the projectile is provided, which can significantly reduce the air resistance during flight compared to the related arrowheads, and since rotation can be induced in itself by the air encountered during the flight, the rotational force and the straightness of the projectile are greatly enhanced, and as a result, it is possible to improve the accuracy of hitting on targets, and increase the destructive power against the target when hitting the target.

1 . A projectile comprising:
 an arrowhead body having a predetermined length and adapted to be coupled to a tip of an arrow shaft of an arrow; and   at least two blades each having a generally triangular shape with its width reducing from a wider proximal portion toward a pointed distal tip portion, the blades protruding at equal intervals from an outer surface of the arrowhead body, and shaped to be curved in a three-dimensional direction to a predetermined direction facilitating a rotation about a longitudinal center axis of the arrow shaft during a flight of the arrow through the air,   wherein an ogive is formed on an outer surface of the blades, the ogive comprising at least one protruded portion and at least one recessed portion formed on the generally triangular shaped side surface of each of the blades,   wherein each of the at least two blades includes a ventilation opening at an inner side thereof to have side winds passed there-through, and a partition extending laterally across the ventilation opening and configured in a three-dimensionally curved shape corresponding to the curved shape of the blade so that the blades are subject to an additional rotation force by the side winds passing through the ventilation opening owing to the three-dimensionally curved shape of the partition.   
     
     
         2 . (canceled) 
     
     
         3 . The projectile according to  claim 1 , wherein the arrowhead body includes an upper body having the ventilation opening at a side thereof and connected to the partition; and
 a coupling shaft integrally connected to a lower portion of the upper body, formed in a cone shape, and coupled to the arrow shaft at a lower end thereof.   
     
     
         4 . The projectile according to  claim 1 , wherein the ogive of the blades comprises one protruded portion formed adjacent to the pointed distal tip portion of the blades and one recessed portion formed at a rearward side from the protruded portion.
