Claims
- 1. In a broadhead assembly for an arrow, said broadhead assembly being of the type including a hub assembly adapted for being retained on the leading end of an arrow shaft, and opposing pairs of broadhead blades mountable in perpendicular relation on said hub assembly and extending radially outwardly therefrom; an improvement wherein said hub assembly includes a central hub with a leading end of said hub having slot means extending axially therein for receiving a forward mounting portion of each said blade, the leading point of each said blade extending forwardly of said leading end of said hub, said opposing pairs of broadhead blades including a pair of primary opposing blades having ends thereof adapted for juxtaposed overlying relation for added strength to the tip of said broadhead, and a pair of secondary opposing blades also adapted for juxtaposed overlying relation and each having a leading end thereof adapted for abutting a side of a primary blade adjacent said leading end thereof.
- 2. The broadhead assembly as defined in claim 1 wherein said hub assembly includes a tubular member sized for fitting over said hub rearwardly adjacent said leading end thereof for covering a rear portion of at least one of said slots, and each of said secondary blades including a detent portion sized to fit into said one slot and be retained therein by said portion of said tubular, member covering said rear portion thereof.
- 3. The broadhead assembly as defined in claim 1 wherein each of said secondary blades includes a notch or open recess extending rearwardly from a forward most portion of said blade for receiving and retaining therein and perpendicularly thereto a forward portion of each of said primary blades.
Background Of The Invention
The application is a continuation-in-part of application Ser. No. 375,487, filed May 6, 1982, now U.S. Pat. No. 4,468,038.
The invention relates to broadhead hunting arrows, and more particularly to an improved broadhead assembly providing completely removable broadhead blades which extend in front of a broadhead hub assembly to define the tip of the broadhead. Such an assembly provides a slashing action when entering a target, rather than a punching action.
Heretofore, arrowheads of the broadhead type having removable razor-edge blades extending radially outwardly of a central hub to which they are attached have been of the type wherein the hub extends to the frontmost point of the arrowhead, i.e., the tip of the broadhead arrow has been an integral part of the hub assembly therefor. Such construction is shown in U.S. Pat. No. 2,373,216 issued to C. J. Zwickey Apr. 10, 1945; and U.S. Pat. No. 2,880,000, issued to H. F. Unger Mar. 31, 1959. In such assemblies, the frontal tip of the broadhead is a separate part from the removable blades therefor. In other broadhead construction, the frontal tip of the broadhead is a conical punching-type tip with the broadhead blades starting behind the conical punching portion. In this type of blade, there is a punching action as the tip enters the target, rather than a preferred slashing action.
Additional hunting arrowheads are disclosed in U.S. Pat. Nos. 1,604,713; 2,005,424; 2,182,320; 2,796,691; 3,578,328; 3,164,385; and 3,945,642.
It is therefore an object of the present invention, generally stated, to provide an improved broadhead assembly for detachably mounting broadhead blades on a hub thereof where the broadhead blades extend forwardly of the hub to create a slashing point, with blades therefore being interchangeable.
Another object of the present invention is the provision of an improved broadhead arrow assembly including a lightweight tubular hub therein which is adapted for receiving and retaining replaceable broadheads adjacent a leading end thereof to define a slashing type point made up completely of interchangeable blades.
The invention is directed to an improved broadhead assembly for an arrow which includes a hub assembly adapted for retention on the leading end of an arrow shaft. A plurality of broadhead blades are mountable in even arcuate relation on the hub assembly and extended radially outwardly therefrom. In the improvement, a leading end of the hub includes a slot means axially therein adapted for receiving a forward mounting portion of each broadhead blade, and the leading point or tip of each blade extends forwardly of the leading end of the hub.
