Broadhead

Abstract

A broadhead includes a body, a blade member, and a plunger. The body defines a target penetrating end. The blade member is positioned partially within an inner volume of the body. The blade member is configured to rotate and translate relative to the body by a pin that is fixedly coupled with the body being received through a slot of the blade member. The blade member is transitionable between a retracted position and a deployed position. The plunger is bias by a spring in a longitudinal direction towards the target penetrating end. The plunger is configured to be received within a recess of the blade member when the blade member is in the retracted position.

         2 . The broadhead of  claim 1 , wherein the blade member comprises a first end and a contact surface, the contact surface configured to be driven by the target as the broadhead plunges into the target such that the blade member is driven to move and rotate along the slot from the retracted position to the fully deployed position. 
     
     
         3 . The broadhead of  claim 1 , wherein the spring-loaded retaining member comprises a plunger and a spring, the plunger configured to engage the notch of the blade member, the notch defined on a rear of the blade member facing the end of the body opposite the target penetrating end. 
     
     
         4 . The broadhead of  claim 1 , wherein the blade member is a first blade member, the broadhead further comprising:
 a second blade member comprising a slot and a notch, the second blade member positioned partially within the inner volume, the pin of the broadhead received within the slot of the blade member, the notch configured to receive the spring-loaded retaining member when the second blade member is in the retracted position, wherein the second blade member is further configured to be driven to move out of the retracted position and into the fully deployed position by contact with the target.   
     
     
         5 . The broadhead of  claim 4 , wherein the first blade member protrudes from a first side of the broadhead and the second blade member protrudes from a second side of the broadhead, wherein the first blade member and the second blade member are configured to move in opposite directions from the body as the target penetrating end of the broadhead penetrates the target. 
     
     
         6 . The broadhead of  claim 1 , further comprising a retaining member and a spring, the spring positioned between the spring-loaded retaining member and the retaining member, the retaining member fixedly coupled with the body. 
     
     
         7 . The broadhead of  claim 1 , wherein the slot of the blade member is positioned proximate a front end of the blade member at which the blade member is coupled with the body via the pin. 
     
     
         8 . A broadhead comprising:
 a body defining a target penetrating end;   a blade member positioned partially within an inner volume of the body and configured to rotate and translate relative to the body by a pin that is fixedly coupled with the body being received through a slot of the blade member, wherein the blade member is transitionable between a retracted position and a deployed position; and   a plunger bias by a spring in a longitudinal direction towards the target penetrating end, the plunger configured to be received within a recess of the blade member when the blade member is in the retracted position.   
     
     
         9 . The broadhead of  claim 8 , further comprising a retaining member coupled in a bore of the body at an end of the body opposite the target penetrating end, the retaining member configured to retain the spring within the bore and also configured to define external threads that protrude from the end of the body opposite the target penetrating end to couple the broadhead with a shaft of an arrow. 
     
     
         10 . The broadhead of  claim 9 , wherein the bore and the inner volume cooperatively form a space within which the plunger and the spring are positioned. 
     
     
         11 . The broadhead of  claim 8 , wherein the body comprises slots formed on opposite sides of the body, the slots providing access to the inner volume through which the blade member protrudes. 
     
     
         12 . The broadhead of  claim 8 , wherein the notch is defined on a shoulder of the blade member. 
     
     
         13 . The broadhead of  claim 8 , wherein the blade member comprises a blade along an external edge that protrudes from the body. 
     
     
         14 . The broadhead of  claim 8 , wherein the blade member is a first blade member, the broadhead further comprising a second blade member, wherein the first blade member protrudes from a first side of the body and the second blade member protrudes from a second side of the body. 
     
     
         15 . The broadhead of  claim 8 , wherein the blade member comprises a locking surface, wherein the locking surface is configured to abut the plunger when the blade member is transitioned into the deployed position to limit movement of the blade member out of the deployed position. 
     
     
         16 . A broadhead comprising:
 a body defining a target penetrating end;   a blade member positioned partially within an inner volume of the body and configured to rotate and translate relative to the body by a pin that is fixedly coupled with the body being received through a slot of the blade member, wherein the blade member is transitionable between a retracted position and a deployed position; and   a plunger bias by a resilient member in a longitudinal direction towards the target penetrating end, the plunger configured to be received within a recess of the blade member when the blade member is in the retracted position.   
     
     
         17 . The broadhead of  claim 16 , further comprising a retaining member coupled in a bore of the body at an end of the body opposite the target penetrating end, the retaining member configured to retain the resilient member within the bore and also configured to define external threads that protrude from the end of the body opposite the target penetrating end to couple the broadhead with a shaft of an arrow. 
     
     
         18 . The broadhead of  claim 17 , wherein the bore and the inner volume cooperatively form a space within which the plunger and the resilient member are positioned. 
     
     
         19 . The broadhead of  claim 16 , wherein the body comprises a first opening on a first side and a second opening on a second side, a bladed edge of the blade member configured to protrude from the first opening on the first side, and a contact surface of the blade member configured to protrude from the second opening on the second side. 
     
     
         20 . The broadhead of  claim 19 , wherein the blade member is a first blade member, the broadhead further comprising a second blade member, a bladed edge of the second blade member configured to protrude from the second opening on the second side, and a contact surface of the second blade member configured to protrude from the first opening on the first side.
