Abstract

A broadhead (10) has deployable cutting blades (24 and 26) which are cammed open from slots (20 and 22) in a cylindrical body (14) as plunger (12) impacts against a game animal. The cutting blades (24 and 26) are connected by pivot pins (32 and 34) to the plunger (12). The cutting blades (24 and 26) are pivotable when the broadhead (10) is in an open position from the open, cutting configuration which causes maximum hemorrhaging to a non-barbed configuration which complies with various state gaming laws. A tubular restraint (11) serves to hold the cutting blades (24 and 26) within their respective slots (20 and 22) during the flight of the arrow. The cylindrical body (14) is threadably (60) connected to a cap (28) and the body (14) and cap (28) include matching tapered sections (64 and 66, respectively) which allow for improved sliding of the plunger (12) through the body (14). A pin (44) has been provided as a camming surface for lower blades (26) to improve the manufacturability of the broadhead (10).

Claims

1. A broadhead, comprising:

a body attachable to an arrow shaft, said body being immovable relative to an arrow shaft once said body is attached to an arrow shaft;

a plunger slidable in a bore in said body;

means for alternatively holding said plunger in a first or second position relative to said body;

two pairs of cutting blades connected by pivot pins to said plunger, a first pair of cutting blades connected at a first location on said plunger, a second pair of cutting blades connected at a second location on said plunger;

means for holding said cutting blades in a retracted position within slots formed in said body when said plunger is in said first position; and

a cam surface connected to said body positioned to open at least one pair of cutting blades to an open position as said plunger moves from said first position to said second position, said first and second pairs of cutting blades being pivotable from said open position to a non-barbed position relative to said body when said plunger is in said second position.

2. A broadhead, comprising:

a body attachable to an arrow shaft, said body being immovable relative to an arrow shaft once said body is attached to an arrow shaft;

a plunger slidable in a bore in said body having a pointed end which projects out of said body from said bore in said body, said plunger being slidable between a first position and a second position relative to said body wherein said pointed end of said plunger is furthest from said body when said plunger is in said first position and wherein said pointed end of said plunger is closest to said body when said plunger is in said second position;

a cutting blade mounted on a pivot pin connected to said plunger, said cutting blade having a pivoting end which pivots on said pivot pin and an opening end which opens away from said body;

a means for holding said cutting blade in a retracted position wherein said pivoting end of said cutting blade is closer to said pointed end of said plunger than said opening end of said cutting blade and wherein said opening end of said cutting blade is held at a first point close to said body; and

a cam surface on said body positioned to open said opening end of said cutting blade to a second point away from said body as said plunger moves from said first position to said second position, said cutting blade being pivotable from said second point away from said body to a third point to form a non-barbed configuration of said cutting blade and said body when said plunger is in said second position.

3. A broadhead, comprising:

a body attachable to an arrow shaft, said body being immovable relative to an arrow shaft once said body is attached to an arrow shaft;

a plunger slidable in a bore in said body having a pointed end which projects out of said body from said bore in said body, said plunger being slidable between a first position and a second position relative to said body wherein said pointed end of said plunger is furthest from said body when said plunger is in said first position and wherein said pointed end of said plunger is closest to said body when said plunger is in said second position;

first and second pairs of cutting blades mounted on first and second pivot pins connected to said plunger at first and second locations, respectively, each of said cutting blades of said first and second pairs of cutting blades having a pivoting end which pivots on said first or second pivot pin and an opening end which opens away from said body;

a means for holding each of said cutting blades in a retracted position wherein said pivoting end of said cutting blade is closer to said pointed end of said plunger than said opening end of said cutting blade and wherein said opening end of each of said cutting blades is held at a first point close to said body; and

cam surfaces on said body positioned to open said opening end of each of said cutting blades to a second point away from said body as said plunger moves from said first position to said second position, each of said cutting blades being pivotable from said second point away from said body to a third point to form a non-barbed configuration of said cutting blade and said body when said plunger is in said second position.
