Reinforced arrow insert

Abstract

An insert for securing a shaft of an arrow to a cutting tip includes a body member extending between a distal end and a proximal end, a stem extending from the distal end of the body member and formed integrally with the body member, the stem including a protrusion extending about a first end of the stem in a circumferential direction, and a sleeve including a countersink. The countersink engages the protrusion of the stem, such that, when the sleeve is disposed about the stem and positioned adjacent the distal end of the body member, the sleeve is coaxial with the stem. The cutting tip is secured to the proximal end of the body member.

What is claimed is: 
     
         1 . An insert for securing a shaft of an arrow to a cutting tip, the insert comprising:
 a body member extending between a distal end and a proximal end;   a stem extending from the distal end of the body member and formed integrally with the body member, the stem including a protrusion having an annular shape and extending about a first end of the stem;   a sleeve including a countersink, the countersink being configured to engage the protrusion of the stem, such that, when the sleeve is disposed about the stem and positioned adjacent to the distal end of, and abutting, the body member, the sleeve is coaxial with the stem, and further wherein said sleeve is sized to receive an arrow shaft at an end of said sleeve opposite from said body member; and   wherein an arrow head is capable of being secured to the proximal end of the body member.   
     
     
         2 . The insert of  claim 1 , wherein a sleeve length of the sleeve is less than a stem length of the stem. 
     
     
         3 . The insert of  claim 1 , further comprising a cavity extending at least partially within the body member, the cavity including an upper cavity portion and a lower cavity portion. 
     
     
         4 . The insert of  claim 3 , wherein the arrow head is received by the lower cavity portion to secure the arrow head to the body member. 
     
     
         5 . The insert of  claim 3 , said protrusion extending from a surface of said body member that is opposite said cavity. 
     
     
         6 . The insert of  claim 5 , said countersink receiving said protrusion. 
     
     
         7 . The insert of  claim 6 , said protrusion and said countersink defining corresponding shapes which engage one another so that the body member is abutting the sleeve. 
     
     
         8 . The insert of  claim 1 , said sleeve comprising an internal wall which separates said countersink from the arrow shaft. 
     
     
         9 . The insert of  claim 8 , said internal wall having a through hole, allowing passage of said stem through said internal wall into said arrow shaft. 
     
     
         10 . The insert of  claim 9 , said internal wall engaging an end face of said arrow shaft on one side. 
     
     
         11 . The insert of  claim 10 , said internal wall being engaged by said protrusion on a side opposite said arrow shaft. 
     
     
         12 . The insert of  claim 11 , said protrusion captured between said body member and said sleeve, within said countersink. 
     
     
         13 . The insert of  claim 12 , said protrusion and said countersink having one or more surfaces for bonding with an adhesive. 
     
     
         14 . The insert of  claim 8 , said sleeve having a first inner diameter, a second inner diameter and a third inner diameter. 
     
     
         15 . The insert of  claim 1 , said stem having one of a smooth outer surface, a plurality of notches, or being rotatable relative to said body member.
