Arrow

Abstract

An arrow ( 10 ) for use in hunting or sport archery, includes a shaft ( 3 ) of variable materials, profiles and lengths; an aerodynamically profiled head ( 4 ) of variable materials and shapes, having blades or knives if designed for hunting use; a nock ( 1 ) for connecting the arrow to the string of a bow; a fletching ( 20 ) for stabilizing the flight of the arrow, which is composed of a plurality of aerodynamically profiled thin vanes ( 2 ), equally spaced over the outer profile of the arrow and defined by an aerodynamically profiled surface ( 2 B) and a transverse foot ( 2 A). Each vane is fitted into a corresponding slit or aperture ( 3 A) formed in the shaft ( 3 ) and its aerodynamically profiled surface ( 2 B) projects out of the slit ( 3 A). Each vane so fitted is held in position by its foot ( 2 A) which is retained within the shaft while abutting against the corresponding surface ( 3 B).

1 . An arrow ( 10 ) for use in hunting or sport archery, comprising a shaft ( 3 ) of variable materials, profiles and lengths; a head ( 4 ) of variable materials and shapes; a nock ( 1 ) for connecting the arrow ( 10 ) to the string of a bow; a fletching ( 20 ) for stabilizing the flight of the arrow ( 10 ), which is composed of a plurality of thin aerodynamically profiled vanes ( 2 ), equally spaced over the outer profile of the arrow ( 3 ) and defined by an aerodynamically profiled surface ( 2 B) and a transverse foot ( 2 A), characterized in that
 a. each vane ( 2 ) is fitted into a corresponding slit or aperture ( 3 A) formed in said shaft ( 3 ) and its aerodynamically profiled surface ( 2 B) projects out of said slit ( 3 A);   b. each vane ( 2 ) so fitted is held in position by its foot ( 2 A) which is retained within the shaft ( 3 ) while abutting against the corresponding surface ( 3 B).   
   
   
       2 . An arrow ( 10 ) as claimed in  claim 1 , characterized in that the assembly of vanes ( 2 ) is held in position against its corresponding surface ( 3 B) by means of a shank ( 9 ) which fits into the shaft ( 3 ), and has a diameter ( 9 A) at least corresponding to the inner cavity defined by the internal diameter of the shaft ( 3 ) less the space occupied by the thickness of the feet ( 2 A). 
   
   
       3 . An arrow ( 10 ) as claimed in  claim 2 , characterized in that said shank ( 9 ) has a second diameter ( 9 B) corresponding to the inner cavity defined by the internal diameter of the shaft ( 3 ). 
   
   
       4 . An arrow ( 10 ) as claimed in  claim 2 , characterized in that said shank ( 9 ) extends from the nock ( 1 ). 
   
   
       5 . An arrow ( 10 ) as claimed in  claim 2 , characterized in that said shank ( 9 ) is a distinct element, separate from the nock ( 1 ). 
   
   
       6 . An arrow ( 10 ) as claimed in  claim 1 , characterized in that said slits ( 3 A) are straight and extend along the axis of the shaft ( 3 ). 
   
   
       7 . An arrow ( 10 ) as claimed in  claim 1 , characterized in that said slits ( 3 A) are curvilinear and extend along the axis of the shaft ( 3 ).
