Abstract

The Adjustable Archery Arrow Insert is a three-piece arrow tip attached to an arrow shaft and includes an arrow tip insert, an arrow tip collar, and an arrow tip. The arrow tip insert is threadably received by the arrow tip collar and is attached to the arrow shaft, where the arrow tip is inserted within, and the arrow tip collar overlaps, the arrow shaft. The arrow tip is inserted through the arrow tip collar and attached directly to the arrow tip insert without protruding into the arrow shaft. Sections of the arrow tip insert may be removed to adjust the overall weight of the arrow. The Adjustable Archery Arrow Insert transfers the impact forces of the arrow tip to the arrow tip insert and arrow tip collar, where the forces are transferred over a larger area thereby minimizing the forces on front edge of the arrow shaft.

Claims

1. An Adjustable Archery Arrow Insert comprising:

an arrow tip collar;

an arrow tip insert threadably inserted into said arrow tip collar; and

an arrow tip inserted through said arrow tip collar and threadably received by said arrow tip insert.

2. The Adjustable Archery Arrow Insert of claim 1, wherein said arrow tip collar comprises:

a tapered body tapering from a first diameter to a second diameter, said taper body formed with a first internal bore having a first diameter and a second internal bore having a second diameter larger than said first diameter, said first internal bore formed with internal threads.

3. The Adjustable Archery Arrow Insert of claim 1, wherein said arrow tip insert comprises:

a stud head having a cylindrical shape, said stud head formed with external threads corresponding to said internal threads of said arrow tip collar;

a cylindrical stud protruding from said stud head and formed with a plurality of circumferential grooves, wherein said circumferential grooves are dimensioned to allow said cylindrical stud to be broken off at said circumferential grooves upon the application of a predetermined force to adjust the weight of said arrow tip insert;

a first internal bore formed into said stud head and formed with internal threads; and

a second internal bore formed into said cylindrical stud.

4. The Adjustable Archery Arrow Insert of claim 3, wherein said cylindrical stud further comprises a plurality of weighted sections, wherein each of said plurality of weighted sections is defined as the portion of said cylindrical stud between two of each said plurality of circumferential grooves, each of said plurality of weighted sections having a predetermined weight.

5. The Adjustable Archery Arrow Insert of claim 4, wherein said predetermined weight of said each of said plurality of weighted sections is between 1.00 grain and 3.00 grains.

6. The Adjustable Archery Arrow Insert of claim 1, wherein said arrow tip comprises:

a base;

a tip formed into said base; and

a cylindrical stud formed into said base opposite said tip, said cylindrical stud formed with external threads corresponding to said internal threads of said arrow tip insert.

7. The Adjustable Archery Arrow Insert of claim 1, wherein said arrow tip insert threaded to said arrow tip collar forms an annular channel between said arrow tip insert and said arrow tip collar.

8. An arrow with an Adjustable Archery Arrow Insert comprising:

an arrow shaft having a point end and a nock end;

an Adjustable Archery Arrow Insert attached to said point end of said arrow shaft, said Adjustable Archery Arrow Insert comprises an arrow tip collar, an arrow tip insert threadably inserting into said arrow tip collar, and an arrow tip inserted through said arrow tip collar and threadably received by said arrow tip insert;

a nock attached to said nock end of said arrow shaft; and

a plurality of fletching attached to said arrow shaft adjacent said nock end.

9. The Adjustable Archery Arrow Insert of claim 8, wherein said arrow tip collar comprises:

a tapered body tapering from a first diameter to a second diameter, said taper body formed with a first internal bore having a first diameter and a second internal bore having a second diameter larger than said first diameter, said first internal bore formed with internal threads.

10. The Adjustable Archery Arrow Insert of claim 8, wherein said arrow tip insert comprises:

a stud head having a cylindrical shape, said stud head formed with external threads corresponding to said internal threads of said arrow tip collar;

a cylindrical stud protruding from said stud head and formed with a plurality of circumferential grooves, wherein said circumferential grooves are dimensioned to allow said cylindrical stud to be broken off at said circumferential grooves upon the application of a predetermined force to adjust the weight of said arrow tip insert;

a first internal bore formed into said stud head and formed with internal threads; and

a second internal bore formed into said cylindrical stud.

11. The Adjustable Archery Arrow Insert of claim 10, wherein said cylindrical stud further comprises a plurality of weighted sections, wherein each of said plurality of weighted sections is defined as the portion of said cylindrical stud between two of each said plurality of circumferential grooves, each of said plurality of weighted sections having a predetermined weight.

12. The Adjustable Archery Arrow Insert of claim 11, wherein said predetermined weight of said each of said plurality of weighted sections is between 1.00 grain and 3.00 grains.

13. The Adjustable Archery Arrow Insert of claim 8, wherein said arrow tip comprises:

a base;

a tip formed into said base; and

a cylindrical stud formed into said base opposite said tip, said cylindrical stud formed with external threads corresponding to said internal threads of said arrow tip insert.

14. The Adjustable Archery Arrow Insert of claim 8, wherein said arrow tip insert threaded to said arrow tip collar forms an annular channel between said arrow tip insert and said arrow tip collar.

15. The Adjustable Archery Arrow Insert of claim 8, wherein said arrow tip is inserted through said arrow tip collar and threadably received by said arrow tip insert wherein said arrow tip is disposed outside of said arrow shaft.
