BRIEF HISTORY

Archery hunters are always looking for new technical advances in broadhead performance and design. Since archery primarily involves a bow or crossbow, arrow, and a broadhead tip, improvements continue to supply the current demand of sporting outdoorsmen worldwide.

An arrow typically comprises of a shaft, insert, feathers or vein fletching, a nock, and most importantly a type of broadhead which is used to subdue the game with effectiveness.

Several advances have been made in broadhead design but nothing compares to the superior strength, penetrating ability, and shocking power of the electrical shocking broadhead.

BACKGROUND OF INVENTION

The invention involves propelling a projectile, namely the arrow and broadhead, from a bow or crossbow, otherwise known as the “launcher” of the arrow and broadhead. A broadhead typically contains a tip for initial penetration, sharpened blades for cutting, a thread mount to secure broadhead to arrow, and most importantly a body to secure components together to form a rigid unit. Broadheads come in a variety of different shapes and sizes depending on the intended application. For example, a field point would be used in competition sport shooting, while a broadhead would be intended for harvesting game. Broadheads contain sharp blades for cutting vital organs such as lungs, heart, arteries, and other vessels which cause rapid hemorrhaging. Quick and humane kills are based on shot placement and amount of tissue that has been penetrated. The volume of tissue that is cut is determined by the blade cutting diameter and depth of penetration by the broadhead.

The two most common types of broadheads are fixed and expandable blade broadheads. Both types of broadheads contain a penetrating tip that allows open up vital organs to bleed out.

SUMMARY OF INVENTION

The current broadhead design solves game recovery abilities substantially by affecting the animal's central nervous system. Another important objective is to disrupt the animal's neurological ability to comprehend its surroundings and to go into a state of instant confusion with muscular activities, especially including vital organs. This neurological disruption in vital organs can instantly kill animal being hunted. The shock of the electrical voltage to vital organs coupled with razor sharp blades will create a sudden forceful impact on the animal. The current broadhead may be used on different sizes and types of animals, selecting the suitable configuration for your hunt.

The current broadhead design composes of several components that are especially resistant to environmental corrosion, strong and yet lightweight, and excellent electrical conductors since we are involving electricity into the whole equation. The structural components mainly consist of anodized aluminum which contains good to excellent physical qualities as mentioned above. The chisel point tip will be manufactured of quality grade hardened steel to withstand tough impacts. Razor sharp blades will consist of quality grade stainless steel, remarkably resistant to environmental corrosion.

BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 shows an exploded side view of complete broadhead assembly. Figure also shows proper assembly methods used in production.

FIG. 2 shows a front and side view of the electronic coil circuit. It also gives design requirements that must be met.

FIG. 3 shows a front and side view of broadhead assembly, which gives general information on some overall dimensions and tip compression requirements.

DETAILED DESCRIPTION OF INVENTION

The invention will now be explained with regard to the included drawing figures. It should also be understood that components may not exactly represent dimensional indications and that they a primarily intended to illustrate the invention and the method of making.

Referring now to FIG. 1, the chisel point tip of the new broadhead is tri-planar in shape. It contains individual relief lobes on each plane for excellent aerodynamic flight and increased penetration efficiency. The tip also contains a rear collar that axially slides towards rear of broadhead. Rear collar functionality will be explained later in this description summary.

Referring to FIG. 1, the copper electrode of the new broadhead is made from copper. Since copper has excellent electrical conductivity characteristics with little resistance, its primary function is to carry electrical current from source coil to tip of broadhead.

Referring to FIG. 1, the compression spring of the new broadhead is used to eliminate any free travel of tip, until force overcomes the spring rate. This will allow tip to slide towards rear of broadhead in such an instance upon tip impact.

Referring to FIG. 1, the threaded lock cap of the new broadhead is threaded on one end to mount to threaded union for sealing. It's also used for axially locating and supporting tip from free movement.

Referring to FIG. 1, the threaded union of the new broadhead is primarily used to connect and seal the threaded lock cap and t-slotted body. It also serves as a support for end of copper electrode. Another important function of the threaded lock cap is to act as a positioning “stop” for the compression spring and electronic coil.

Referring to FIG. 2, the electronic coil of the new broadhead provides the needed voltage to the circuit. It's constructed from various electrical components that are sealed from environmental conditions. The coil also contains a concave contact electrode for the copper electrode to touch that acts as the “switch” of the circuit. The electronic coil will operate on supplied voltage provided by internal batteries. Operating temperature must be within specified limit to function.

Referring to FIG. 1, seal ring of the new broadhead provides the needed sealing and wear characteristics for assembly and disassembly routines. Its main function is to seal threaded union to t-slotted body.

Referring to FIG. 1, the batteries of the new broadhead are used to supply the electrical coil with much needed voltage. The batteries must be positioned to the rear spring of the electronic coil in series to achieve voltage.

Referring to FIG. 1, the mounting stem of the new broadhead is used to secure broadhead to arrow by means of threading stem into arrow insert. The stem is held into place by pressing through t-slotted body bore to bottom of mounting stem collar. It also provides means of axially locating broadhead for precise flight.

Referring to FIG. 1, the triangular blades of the new broadhead are used to cut vital organs of animal. They are inserted into t-slots of body located around tapered circumference. Sharp edge of blade is always positioned outwards so that cutting can be achieved. Tangs that are located on bottom edge of blade hold blades securely into place.

Referring to FIG. 1, the t-slotted body of the new broadhead is used to form a “backbone” for the rest of the broadhead components. The body contains an external thread that seals and positions the threaded union in place. It also holds all other components in place to prevent unwanted movement.

Referring to FIG. 3, the tip activation requirements of the new broadhead are mentioned in further detail. The tip must axially slide rearward to a position and force specified on the drawing to activate electrical voltage ignition.
