Feathers of an arrow

Abstract

The present invention relates to the improved feathers of an arrow, and more particularly, to the improved feathers of an arrow, which prevent instability of flight caused by a vortex generated during the flight of the arrow by forming a plurality of arrow feathers attached to the arrow, which has a cross section which is a curved surface and integrally forming an auxiliary surface having one surface which is the curved surface with the arrow feather to guarantee stable flight.

1 . Improved feathers of an arrow in which arrow pile and a nock are formed at both ends of an arrow shaft and a plurality of arrow feathers are bonded to the surface of the arrow shaft to be integrally formed at the front of the nock, comprising:
 an attachment surface  120  curved in a direction opposite to a curved direction of a body  110  and an auxiliary surfaced  130  curved in the same or similar shape as a curved shape of the body by separating a part of the inner surface body  110 , which are integrally formed at a lower portion of the body  110  curved in one direction.   
     
     
         2 . The improved feathers of an arrow of  claim 1 , wherein the plurality of auxiliary surfaces  130  is formed on the inner surface of the body  110 . 
     
     
         3 . The improved feathers of an arrow of  claim 1 , wherein the auxiliary surface  130  has a smooth flat plate shape. 
     
     
         4 . The improved feathers of an arrow of  claim 1 , wherein the attachment surface  120  is curved with the same arc as the surface of the arrow shaft  11  to which the arrow feathers  100  are attached.
