Claim 0:
1. An expandable, rearward deploying broadhead for impacting and penetrating a target when attached to an arrow, the broadhead comprising:
a ferrule, a pair of rear deploying blades, a cam member, and a spring;
the ferrule being an elongate member extending along a longitudinal axis between axially opposite leading and trailing ends of the ferrule;
the ferrule comprising a penetrating tip portion being disposed at the leading end of the ferrule, a blade-holding portion extending axially from the penetrating tip portion, and a shank extending axially away from the blade-holding portion to the trailing end of the ferrule, the shank being configured to attach the broadhead to an arrow;
the blade-holding portion of the ferrule comprising a slot extending axially between spaced apart opposite leading and trailing end surfaces of the slot, the slot extending towards the trailing end of the ferrule as the slot extends from the slot leading end surface to the slot trailing end surface;
the pair of blades being movably mounted in the slot between retracted and extended positions, the pair of blades being against the leading end surface of the slot when the pair of blades are in the retracted position and the pair of blades being against the trailing end surface of the slot when the pair of blades are in the extended position, the pair of blades translating and pivoting with respect to the ferrule when moving from the retracted position to the extended position;
the cam member being disposed on the shank and movable axially with respect to the shank, the spring applying a force to the cam member urging the cam member towards the blade-holding portion of the ferrule when the broadhead is attached to the arrow;
the spring being disposed on the shank and urging the cam member against the blades when the blades are in the retracted position when the broadhead is attached to the arrow, the cam member urging the blades axially against the leading end surface of the slot and urging each blade into pivotal engagement against a member disposed in the path of pivotal movement of the blade that resists continued pivotal movement of the blades whereby the blades are maintained in the retracted position during flight of the arrow towards the target.
