Benefits of technology

[0011] A principal object and advantage of the present invention is that it provides for maximum penetration with a target drawing force to create excessive hemorrhaging caused by the broadhead cutting blades causing a more efficient mortal wound.
[0012] Another object and advantage of the present invention is that it provides for a quick kill, successful retrieval, avoiding prolonged pain and suffering, and permits the avoidance of the long tracking process.
[0013] Another object and advantage of the present invention is that it provides accurate flight pattern caused by aggressive rotating of the broadhead due to the rifling design thereof.
[0014] Another object and advantage of the present invention is that the tip is self-penetrating and drawing inwardly which will avoid bone deflection and actually will draw the arrow through the target animal.
[0015] Another object and advantage of the present invention is that it provides for minimal friction with continuous cutting through the spiraling drawing energy action of the tip.
[0016] Another object and advantage of the present invention is that the tip spiraling or auger rotation effect reduces broadhead energy loss typical with known arrow shaft friction and torque.

Problems solved by technology

However, with faster and more powerful bows comes problems associated with the accuracy of arrow placement.
These known conventional broadhead blades seriously impede the rotation of the arrow and may in fact cause the arrow to wobble and deflect offline.
Bones cause the arrow to deflect and many times break the blade or divert the blade away from intended vital organs.
However, because the spiral blades have only the leading end locked down to the arrowhead, they appear to be fragile and may easily break upon impact with the target.
This is because they lack appropriate strengthening connections between the forward and rearward blade components and are completely mounted within a single slot within the ferrule.
The individual blades have a rearwardly located slight airfoil shape which may slightly assist in rotating the blade but offer little assistance in penetration.

embodiment 140

[0035] A second broadhead tip embodiment 140 assists in broadhead 100A rotation about axis 142. The broadhead tip or trocar 140 has a generally smooth cut out portion 144 from left to right downwardly to create a slope 146 and a pulling edge 148. By this arrangement, air foil sloping surface 146 assists in rotation of the broadhead 100A along with the arrow 90 in the same rotational fashion as blade assemblies 114 as shown in arrow A about axis 142. The pulling or cutting edge 148 pulls the tip 140 forward through the animal and through bone as it rotates at great speed, again, assisting the blade assemblies 114.

[0036]FIGS. 4 and 5 show an archery field tip 150 similarly cut to the broadhead tip 140. Field tip 150 rotates about axis 152 and has a cut out portion 154 creating a slope 156 and suitably a pulling or cutting edge 158, all of which assist in rotation of the field tip 150 and arrow about axis 152, as shown with arrow B.

second embodiment

[0037]FIGS. 6, 7, and 8 show an archery field tip 160. Field tip 160 rotates about axis 162 and has a cut-out portion 164 creating an air foil ramp or slope 166 and suitably a pulling or cutting edge 168a, both of which assist in rotation of the field tip 160 and arrow about axis 162 as shown with arrow C. The cut-out portion 164 forms a definable trough 170 having the pulling or cutting edge 168a as a leading edge and air foil ramp 172 as a trailing edge. Trough 170, cutting edge 168a and ramp edge 172 all assist in rotation of the field tip 160 and arrow about axis 162.

[0038] Field tip 160 may further comprise a second trough 174, second ramp edge 176, a second air foil ramp 177 and second pulling edge 168b, all suitably symmetric with the first trough 170, first ramp edge 172, first air foil ramp 166 and first cutting edge 168a, and all assist in rotation of the field tip 160 and arrow. Furthermore, the cutting edges 168a and 168b assist in pulling the tip 160 forward through the...

Abstract

A broadhead tip or field tip for an archery arrow that is chiseled or troughed forming a sloping surface and a cutting edge.

Description

BACKGROUND OF THE INVENTION [0001] This application is a continuation-in-part of application Ser. No. 10 / 862,648, filed Jun. 7, 2004, entitled “HELICAL BROADHEAD”.[0002] The present invention relates to an archery broadhead tip or field tip, and more particularly, to a broadhead tip or field tip with a sloping surface, trough or ramp which imparts spin to the arrow in flight to increase accuracy, penetration and hemorrhaging of the target animal. [0003] A bow hunter's goal at all times is to accurately place a shot in a killing zone of a big game animal with maximum penetration to establish excessive hemorrhaging and ultimately result in a quick kill and successful animal retrieval thereby avoiding excessive tracking efforts, prolonged pain and suffering to be experience by the animal. [0004] To achieve the hunter's goal, the archery industry has provided faster shooting and more powerful bows with increased percentage of “let off” allowing the hunter to hold the drawn bow longer wh...
