Abstract:
The present invention comprises a novel broadhead generally consisting of a means to attach said broadhead to an arrow shaft, a ferrule with longitudinal slots for recessed blades and a perpendicular circular indentation to hold an o-ring, a tip to provide aerodynamic flight and a cutting surface, pivoting forward deploying blades, and a delayed deployment mechanism designed to trigger deployment of the blades after the broadhead has entered the target. An o-ring may be positioned on the ferrule to hold the blades in the recessed position until deployment is triggered by the delayed deployment mechanism. In preferred embodiments, the design of the pivot point and the slots in the ferrule only allow the blades to deploy to a position slightly greater than perpendicular to the ferrule. Also in preferred embodiments, the blades are fully recessed and will remain so until the broadhead has entered the target.

Claim (Index 1):
An arrowhead tip for attachment to an arrow shaft, said tip comprising:\n a) a ferrule, said ferrule elongated and concentric in shape and having a central, elongate axis, a distal end, a proximal end, a plurality of longitudinal slots cut from the surface to the elongate axis, connecting with one another at the elongate axis, and extending longitudinally along the elongate axis from the distal end towards the proximal end of said ferrule, and a blade connection point within each longitudinal slot near the proximal end of said slot; b) a plurality of blades corresponding in number with the longitudinal slots of the ferrule and coupled to the blade connection point in one of the longitudinal slots, each blade including a mounting end and a tip; c) a triggering device having a connecting end, an opposite end, a leg extending roughly perpendicular from the connecting end to the opposite end and slightly shorter in length than the longitudinal slots of the ferrule, and an actuating catch at the opposite end, said actuating catch protruding roughly perpendicular from said leg; d) a deployment assist slide generally shaped to loosely fit internal within the longitudinal slots in the ferule and having connecting points to accept the triggering device, and a proximal end shaped such that when moved from the distal end of the ferrule along the elongate axis towards the proximal end of the ferrule said proximal end of the slide engages the tips of the blades and forces the blades in the longitudinal slots of the ferrule to open radially away from the ferrule starting at the distal end; and e) a tip integrally attached at the distal end of said ferrule and tapered symmetrically about the elongate axis to form a point oriented in a proposed direction of flight; f) wherein the proximal end of the ferrule is configured along the elongate axis to enable the arrowhead tip to attach securely to the distal end of the arrow shaft; g) wherein each of said blades is pivotally coupled at the mounting end to the blade connection point within the corresponding longitudinal slot of the ferrule such that the blades may pivot between a retracted position with each blade fully recessed into the corresponding longitudinal slot along the elongate axis and an extended position with the tip of each blade extending radially outward from the blade connection point within the corresponding longitudinal slot; h) wherein the deployment assist slide rests within the longitudinal slots of the ferrule at the distal end of the ferrule when the blades are in the retracted position and when said opening assist slide is moved within the longitudinal slots from the distal end of the ferrule towards the proximal end the opening assist slide engages the tips of the blades and forces the blades in the longitudinal slots of the ferrule to open radially away from the ferrule starting at the distal end; and i) wherein the triggering device is connected at the connecting end to one of the connecting points of the deployment assist slide and the leg of the triggering device lays within one of the longitudinal slots with only the actuating catch protruding outward from the concentric surface of the ferrule at the proximal end of the longitudinal slots.
