Arrow for crossbow

Abstract

The crossbow arrow includes an arrow shaft having a head portion at one end and a tail portion at the other end and at least two wing members protruding beyond the transverse dimensions of the arrow shaft and extending substantially between the head portion and the tail portion. The wing members are made of a rigid and hard material and simultaneously perform the function of feathering for stabilizing the arrow in flight and the function of cutting blades for increasing destructive ability of the arrow. The technical effect is reduction in the number of parts used, reduction in a total weight of the arrow, increase of the construction rigidity, improvement of aerodynamic properties and destructive ability of the arrow.

1 . A crossbow arrow, comprising:
 an arrow shaft having a shape substantially elongated in the a longitudinal direction, said arrow shaft comprising a head portion at one end and a tail portion at another end; and   at least two wing members protruding beyond transverse dimensions of said arrow shaft and extending substantially from the head portion to the tail portion;   wherein the wing members are comprised of a rigid and hard material and simultaneously perform the function of feathering for stabilizing arrow in flight and the function of cutting blades for increasing the arrow destructive ability.   
     
     
         2 . The arrow according to  claim 1 , wherein each wing member comprises, in the direction from the head portion to the tail portion, at least one region expanding from arrow shaft and at least one region narrowing to arrow shaft. 
     
     
         3 . The arrow according to  claim 2 , wherein each wing member is made trigonal, with an obtuse angle between the lateral side of the expanding region and the lateral side of the narrowing region, or polygonal with more than two lateral sides, or with a shape of the lateral sides, which combines straight and curved lines, or with a shape of the lateral sides in the form of a curved line. 
     
     
         4 . The arrow according to  claim 3 , wherein at least one of the lateral sides of the wing member has a sharp cutting edge. 
     
     
         5 . The arrow according to  claim 4 , the wherein said sharp cutting edge is made as a straight line, or a broken line, or a line combining straight regions and curved regions. 
     
     
         6 . The arrow according to  claim 1 , the wherein a base of the wing member has a rectangular shape, or a rectangular shape with leveled corners, or a rhomb-like shape, or a pentagonal shape with a rectangular region and a triangular region.
