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. A method of attaching an adjustable arrow shaft insert to an arrow shaft comprising the steps of:

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

providing an adjustable arrow shaft insert having an arrow tip collar, an arrow tip insert threadably inserted into said arrow tip collar, an arrow tip inserted through said arrow tip collar and threadably received by said arrow tip insert; and

attaching said adjustable arrow shaft insert to said arrow shaft.

2. The method of attaching an adjustable arrow shaft insert to an arrow shaft 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 method of attaching an adjustable arrow shaft insert to an arrow shaft of claim 2, 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;

a second internal bore formed into said cylindrical stud; and

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.

4. The method of attaching an adjustable arrow shaft insert to an arrow shaft of claim 3, 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.

5. A method of attaching an adjustable arrow shaft insert to an arrow shaft comprising the steps of:

providing an arrow tip collar;

providing an arrow tip insert;

threading said arrow tip insert into said arrow tip collar;

attaching said arrow tip collar and said arrow tip insert to said arrow shaft

providing an arrow tip; and

inserting said arrow tip into said arrow tip collar and threading said arrow tip into said arrow tip insert.

6. The method of attaching an adjustable arrow shaft insert to an arrow shaft of claim 5, wherein said arrow tip collar comprises:

a tapered body tapering from a first diameter to a second diameter, said tapered 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.

7. The method of attaching an adjustable arrow shaft insert to an arrow shaft of claim 6, 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.

8. The method of attaching an adjustable arrow shaft insert to an arrow shaft of claim 7, 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.
