Dual function broadhead assembly

Abstract

A broadhead assembly includes a body extending from a first end to a second end, one or more blades each having a leading end and a trailing end, a collar having a first portion and a second portion, and a tip. The second portion retains a portion of the leading end of each of the one or more blades and the tip couples to the first end of the of the body. The assembly is configured for use in both fixed blade and mechanical or deployable modes of operation.

         3 . The broadhead assembly of  claim 1 , wherein the tip includes an apex and a plurality of tip blades. 
     
     
         4 . The broadhead assembly of  claim 1 , wherein at least one of the blade edges is configured to be retained in the one or more axial grooves of the body when in a retracted position. 
     
     
         5 . The broadhead assembly of  claim 4 , wherein the collar is configured to fracture when the tip impacts a target and release the leading ends of the one or more blades. 
     
     
         6 . The broadhead assembly of  claim 5 , in which the one or more blades are moved from a retracted position to an expanded position where the at least one of the blade edges is released from the one or more axial grooves of the body upon fracture of the collar. 
     
     
         7 . The broadhead assembly of  claim 1 , wherein the body further comprises:
 an annular shoulder configured to prevent over insertion of the body into an arrow; and   an arrow coupling portion configured to couple the body to a portion of the arrow.   
     
     
         8 . The broadhead assembly of  claim 1 , wherein the collar further comprises an interior surface defining a central bore, the central bore including a plurality of arcuately-shaped radial portions disposed circumferentially on the interior surface. 
     
     
         9 . A broadhead assembly comprising:
 a body having an axis extending between a first end and a second end, the body including one or more axial grooves;   a plurality of blades each having a leading end and a trailing end, and wherein each of the plurality of blades have two or more blade edges and are configured to be removably coupled to a portion of the body;   a tip configured to engage a portion of the first end of the body; and   a collar having a first portion and a second portion and including an inner surface defining a central through bore extending from the first portion to the second portion, the central through bore including a plurality of arcuately-shaped radial portions disposed circumferentially on the interior surface.   
     
     
         10 . The broadhead assembly of  claim 9 , wherein the tip includes an apex and a plurality of tip blades. 
     
     
         11 . The broadhead assembly of  claim 9 , wherein at least one of the blade edges is configured to be retained in the one or more axial grooves of the body when in a retracted position. 
     
     
         12 . The broadhead assembly of  claim 9 , wherein the collar is configured to fracture and release the leading ends of the one or more blades when the tip impacts a target. 
     
     
         13 . The broadhead assembly of  claim 12 , in which the plurality of blades move from a retracted position to an expanded position in which the at least one of the blade edges is released from the one or more axial grooves of the body upon fracture of the collar. 
     
     
         14 . The broadhead assembly of  claim 9 , wherein the body further comprises:
 an annular shoulder configured to prevent over insertion of the body into an arrow shaft; and   an arrow coupling portion configured to couple the body to a portion of the arrow shaft.   
     
     
         15 . A method of hunting game with a broadhead assembly, the method comprising:
 providing a body having an axis extending between a first end and a second end, the body including one or more mounting points;   rotatably coupling a trailing end of each of a plurality of blades to the one or more mounting points, wherein each of the plurality of blades has two or more blade edges;   coupling a collar to the first end of the body, the collar having an interior surface defining a central through bore extending between a first portion and a second portion of the collar, wherein the second portion is configured to retain a portion of a leading end of each of the plurality of blades;   coupling a tip to the first end of the body, the tip configured to engage the second end of the collar; and   coupling the second end of the body to an arrow shaft and launching at a target animal using a bow.   
     
     
         16 . The method of  claim 15 , wherein the tip includes an apex and a plurality of tip blades. 
     
     
         17 . The method of  claim 15 , wherein the body includes one or more axial grooves configured to retain at least one of the blade edges when the plurality of blades is in a retracted position. 
     
     
         18 . The method of  claim 15 , wherein the collar is configured to fracture and release the leading end of each of the plurality of blades when the tip impacts the target animal. 
     
     
         19 . The method of  claim 17 , in which the plurality of blades move from a retracted position to an expanded position in which the at least one of the blade edges is released from the one or more axial grooves of the body upon fracture of the collar. 
     
     
         20 . The method of  claim 15 , wherein the body further comprises an annular shoulder configured to prevent over insertion of the body into the arrow shaft.
