Abstract

An arrowhead assembly and a method for assembling an arrowhead are provided. The arrowhead of the disclosure is secured to an inside portion of the arrow shaft and the outside portion of the arrow shaft. In some embodiments the arrow tip threads into an insert that is secured within the tip of the arrowhead. Also, in some embodiments, a sleeve extends over the end of the arrow shaft and is radially compressed onto the shaft.

Claims

1. An arrowhead assembly comprising:

a sleeve constructed to extend over and clamp concentrically around an arrow shaft; and

an arrow point including;

a tip, a shaft, the shaft having a first portion configured to be secured to an inside of the arrow shaft; and

a second portion fitted to the sleeve.

2. The arrowhead assembly according to claim 1, further comprising an insert configured to be fixed within an arrow shaft and configured to engage the first portion of the shaft of the arrow point.

3. The arrowhead assembly according to claim 1, further comprising a collar constructed to concentrically compress the sleeve against the arrow shaft.

4. The arrowhead assembly according to claim 3, wherein the collar is positioned over and around the first portion of the shaft.

5. The arrowhead assembly according to claim 1, further comprising a blade constructed to engage the sleeve, the blade including:

a cutting edge; and

a base edge, the base edge including a rear retainer and a front retainer, wherein the front retainer is configured to be held between the arrow point and the sleeve.

6. The arrowhead assembly according to claim 5, wherein the base edge is constructed to be received in a groove on the sleeve.

7. The arrowhead assembly according to claim 6, wherein the rear retainer is configured to engage the sleeve and bias the blade radially inward when the arrow point is secured to the shaft.

8. The arrowhead assembly according to claim 1, wherein the diameter of the sleeve at an end proximate the tip of the arrow point is substantially the same as a largest diameter of the tip of the arrow point.

9. The arrowhead assembly according to claim 1, further comprising a pivot blade, the pivot blade being pivotally connected to the sleeve.

10. A method of assembling an arrowhead including:

connecting an arrow tip to an inside hollow portion of an arrow shaft and compressing a shaft sleeve around the outside of the arrow shaft.

11. The method of claim 10, wherein the step of compressing a shaft sleeve around the outside of the arrow shaft includes threading a compression collet around the shaft sleeve.

12. The method of claim 10, wherein the step of connecting an arrow tip to an inside of an arrow shaft includes threading a portion of the arrow tip to an insert secured to the hollow portion of an arrow shaft.

13. The method of claim 10, further comprising the step of positioning a plurality of blades within grooves on the shaft sleeve.

14. The method of claim 13, wherein the step of connecting the arrow tip to an inside hollow portion of an arrow shaft secures the blades to the shaft sleeve.

15. An arrowhead assembly comprising a plurality of blades spaced around an arrow shaft, wherein the arrowhead assembly is configured to be secured axially to the inside of an arrow shaft and radially to an outside of the arrow shaft.

16. The arrowhead assembly according to claim 15, wherein an arrow tip is configured to be secured axially to the arrow shaft and a sleeve is configured to be secured radially to the outside surface of the arrow shaft.

17. The arrowhead assembly according to claim 16, wherein the arrow tip includes a centering portion that is configured to mate with the sleeve and includes a shaft portion that is configured to be positioned concentrically within the sleeve.

18. The arrowhead assembly according to claim 17, wherein the arrowhead assembly is constructed such that a portion of the arrow tip shaft overlaps the arrow shaft and the sleeve.

19. The arrowhead assembly according to claim 17, wherein the portion of the arrow tip shaft that overlaps the arrow shaft and the sleeve is constructed to engage an insert concentrically positioned within the arrow shaft and the sleeve.

20. The arrowhead assembly according to claim 15, further comprising:

an arrow tip, the arrow tip including an arrow point, the arrow point being connected to a shaft, the shaft having a larger diameter portion and a smaller diameter portion;

an insert, the insert being configured to be fixed within an end of an arrow shaft and connected to the larger diameter portion of the shaft;

a sleeve, the sleeve including a first end configured to abut the arrow point and a second end that extends over the insert and the arrow shaft; and

a compression collar configured to be threaded onto a second end of the sleeve to compress the sleeve onto the outside surface of the arrow shaft.

21. An arrow comprising:

a shaft;

a tip arrangement including;

a sleeve having a rear portion that is clamped about an exterior of the arrow shaft; and

an arrow point having a shaft that extends through the sleeve, the shaft being anchored to an interior of the arrow shaft.

22. The arrow according to claim 21, further comprising a plurality of blades attached to the sleeve.
