Arrow nock including metal reinforcement member

Abstract

The present invention relates to an arrow nock having a metal insert therein. The arrow nock is provided for installation at the fletched end of an arrow shaft, and is configured to receive a bowstring of a hunting bow therein. The arrow nock imparts the force of the bowstring into the arrow shaft to propel the arrow to the target. Repeated use can cause failure of the nock. The solution is to provide the nock with a reinforcement to prevent the failure or breakage of the arrow nock and/or shaft. A reinforcing rod, preferably of metal, extends the length of the nock and is molded into the arrow nock. Optionally, the rod may extend beyond the nock body and into the arrow shaft providing additional support.

1 . A nock for an arrow that is configured to be propelled by a bowstring, the nock comprising:
 a body having a nock portion and an attachment portion;   the nock portion having a pair of opposed arms forming a bowstring opening at the first end and a closed second end, the arms spaced at the first open end to allow the bowstring to pass between the arms;   the attachment portion having a circular cross-section sized to enter the arrow shaft fletched end; and   a reinforcing member connecting the nock portion and the attachment portion and having a length extending from the attachment portion into the arrow shaft.   
   
   
       2 . The nock of  claim 1 , wherein the attachment portion interference fits within the arrow shaft, the nock body retained on the shaft by friction. 
   
   
       3 . The nock of  claim 1 , wherein the attachment portion, nock portion and reinforcing member are integrally formed. 
   
   
       4 . The nock of  claim 1 , wherein the nock body is formed by injection molding. 
   
   
       5 . The nock of  claim 1 , wherein the pair of arms diverge at the open end. 
   
   
       6 . The nock of  claim 1 , wherein the pair of arms converge at the open end. 
   
   
       7 . The nock of  claim 1 , wherein the attachment portion and the nock portion are substantially the same length. 
   
   
       8 . The nock of  claim 1 , wherein the reinforcing member is a rod made of metal. 
   
   
       9 . The nock of  claim 1 , wherein the reinforcing member comprises a rod that extends from the closed second end to beyond the attachment portion. 
   
   
       10 . The nock of  claim 1 , wherein the reinforcing member is adhesively retained in the nock. 
   
   
       11 . A nock for an arrow, the arrow comprised of a shaft having a first end for receiving a broadhead and a second end for receiving the nock, the shaft having fletching at the rear of the shaft, the arrow for use with a bow having a bowstring, the nock for disengageably engaging the rear fletched end and the bowstring, wherein the nock comprises:
 a body having an end including a portion that engages the tail of the arrow shaft such that the body is retained on the shaft;   the body having a pair of arms spaced apart to form a bowstring notch at another end, the body further having a stop opposite the notch to prevent the arms from being inserted into the arrow shaft; and   a reinforcing member extending from the pair of arms to beyond the body engaging the tail of the arrow.   
   
   
       12 . The nock of  claim 11 , wherein the pair of arms diverge at the open end. 
   
   
       13 . The nock of  claim 11 , wherein the pair of arms converge at the open end. 
   
   
       14 . The nock of  claim 11 , wherein the reinforcing member is metal. 
   
   
       15 . The nock of  claim 11 , wherein the nock is an integral member. 
   
   
       16 . The nock of  claim 11 , wherein the end portion and the body are substantially the same length. 
   
   
       17 . The nock of  claim 11 , wherein the reinforcing member is a unitary member approximately the length of the nock body and engaging portion and embedded within the nock body and engaging portion from approximately the closed end of the arms to beyond the end of the engaging portion. 
   
   
       18 . The nock of  claim 13 , wherein nock is configured such that during use, the pair of arms flex outwardly to allow the bowstring to engage the nock
