Mechanical anti-wedging and controlled deployment broadhead
DCFirst Claim
1. An arrowhead for a broadhead arrow comprising:
- an elongated generally cylindrically shaped body having a forwardly projecting tip portion,said body being provided with a diametrically extending through-slot,a pair of cutting blades pivotally mounted on said body and being movable about spaced parallel pivot axes between a retracted position disposed substantially within said through-slot, and a deployed position extending outwardly from said body,each of said cutting blades having an actuating lever projecting outwardly from said body when the associated of said blades is in its retracted position; and
at least a portion of the pivot axis of each of said blades being located longitudinally closer to said tip portion of said body than the associated of said actuating levers, and the center of gravity of each of said cutting blades being disposed laterally inwardly from the associated of said pivot axis, whereby said cutting blades are retained in the respective retracted positions during acceleration of the arrow and moved toward their respective deployed positions upon deceleration of the arrow.

Abstract
An anti-wedging, controlled deployment broadhead with an over-center of gravity blade geometry for bow-hunting that has the ability to penetrate bone and soft tissue deeply before deploying its blades while conserving the highest possible amount of kinetic energy in flight and at target. The inventive device includes the one-piece body, specially aligned and faceted cutting tip, blades, O-ring, and set screws. The blades have independent pivots that also act as travel limiters, are arch shaped with very sharp leading edges and a J-shaped lever. The center of gravity of each of the blades is oriented so as to insure retaining each blade in its respective retracted position during acceleration and assisting in deployment thereof during deceleration. The device with its special body and blade geometry now allows for more energy and blade area to be delivered to the vital organs of game to facilitate a faster and more humane harvest.

18. An arrowhead adapted to be operatively associated with an arrow and comprising:
-
a body having a diametrically extending through-slot, a pair of retractable cutting blades disposed within said through-slot and being independently movable between retracted and deployed positions, means defining a pair of laterally spaced parallel pivot axes arranged generally perpendicular to said through-slot and about which said cutting blades are pivotable between said retracted and deployed positions, the center of gravity of each of said blades being disposed laterally inwardly from the associated of said pivot axis, whereby said cutting blades are retained in the respective retracted positions during acceleration of the arrow and moved toward their respective deployed positions upon deceleration of the arrow. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. An arrowhead for use with a broadhead arrow, said arrowhead comprising:
-
an elongated body having a forwardly projecting tip portion and major and minor diameter portions, said body having a longitudinally extending through-slot formed therein, a pair of cutting blades, each of said blades having an actuating lever and being pivotally mounted on by means of a pivot element disposed within a pivot bore formed in said body, whereby said cutting blades are and being pivotable between a first position substantially retracted within said through-slot and a second position wherein the cutting edges of said cutting blades are deployed outwardly from said body, the furthest forward position of said actuating levers being no further forward than the forward-most portion of the associated said pivot element bores, the pivotal axis of each of said cutting blades being disposed no further forward of said body than said major diameter portion thereof, wherein, the center of gravity of each of said cutting blades is disposed laterally inwardly from the associated of said pivot axis, whereby said cutting blades are retained in their respective retracted positions during acceleration of the arrow and move toward their respective deployed positions upon deceleration of the arrow. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)

53. In combination in a broadhead arrow,
an arrowhead assembly comprising a longitudinally disposed body having a forwardly projecting tip portion and rearward mounting portion adapted to be operatively secured to the shaft of the arrow, said body being provided with a diametrically extending through-slot, a pair of cutting blades pivotally mounted within said through-slot of said body and each being movable about a respective pivot axis between a retracted and deployed position, each of said cutting blades comprising actuating lever means projecting outwardly from one side of said body and a cutting edge projecting outwardly from the opposite side of said body when each said cutting blade is disposed in its retracted position.
