Abstract

The invention involves an arrow system having a shaft having a first end and an insert receptive of a standard point, the insert being disposed completely within the first end of the shaft. An insert installation tool may be used as part of the invention to facilitate insertion of the insert into the first end of the shaft. The invention further includes a reduced diameter hunting arrow shaft that maintains sufficient spine and weight characteristics. The reduced diameter hunting arrow shaft is receptive of standard or non-standard internal components for increasing arrow penetration and shot accuracy. Still further, the invention includes an arrow tip assembly including a male insert and a female point to assist in aligning points with arrow shafts.

Claims

1. An arrow, comprising:

a shaft having a first end;

an insert receptive of a point, the insert being recessed within the first end of the shaft.

2. An arrow according to claim 1 wherein the point comprises a shoulder and the shaft comprises an end wall;

wherein the insert is seated at a depth within the shaft such that the shoulder of the point bears only against the end wall of the shaft when the point is fully engaged with the insert.

3. An arrow according to claim 1 wherein the shaft comprises an inside diameter of approximately 0.204 inches, a spine of approximately 0.500 inches or less, and an outside diameter less than 0.275 inches.

4. An arrow according to claim 1 wherein the shaft comprises an inside diameter of approximately 0.200 inches, a spine of approximately 0.500 inches or less, and an outside diameter less than 0.275 inches.

5. An arrow according to claim 1 wherein the insert comprises a substantially constant outside diameter and a threaded recess.

6. An arrow according to claim 5 wherein the substantially constant outside diameter comprises a plurality of ridges.

7. An arrow according to claim 1 wherein the shaft comprises an FRP shaft.

8. An arrow according to claim 1 wherein the shaft comprises an aluminum-carbon shaft.

9. An arrow according to claim 1 wherein the point comprises a shoulder and a shank, and the shaft comprises an end wall and an inside surface;

wherein the shoulder of the point bears directly against the end wall of the shaft and the shank bears directly against the inside surface of the shaft.

10. An arrow according to claim 1 wherein the shaft comprises:

an end wall;

an inside surface;

a chamfer between the end wall and the inside surface.

11. An arrow system, comprising:

a hunting arrow, comprising;

a shaft having a first end and a first end wall;

an insert being recessed within the shaft;

a point having a head and a shoulder;

wherein the point shoulder directly bears exclusively against the first end wall.

12. An arrow system according to claim 11 wherein the shaft comprises an inside diameter of approximately 0.204 inches, a spine of approximately 0.500 inches or less, and an outside diameter less than 0.275 inches.

13. An arrow system according to claim 11 wherein the shaft comprises an inside diameter of less than 0.200 inches, a spine of approximately 0.500 inches or less, and an outside diameter less than 0.275 inches.

14. A hunting arrow, comprising:

a shaft having a first end defining a first end wall;

an insert having a first end defining a first end wall, the insert being disposed inside the shaft such that the first end wall of the insert is interior to the first end wall of the shaft.

15. An arrow, comprising:

an arrow shaft having a first end, a first end wall, an inside surface, and an outside surface;

an insert completely recessed within the first end of the arrow shaft;

a point connected to the insert, the point comprising a shoulder and a shank extending from the shoulder;

wherein the shoulder bears only against first end wall of the arrow shaft and the shank bears directly against the inside surface of the arrow shaft.

16. An arrow according to claim 15, further comprising a chamfer between the end wall and the inside surface.

17. An arrow according to claim 15 wherein the shoulder is flush with the outside surface of the arrow shaft.

18. An arrow according to claim 15, wherein the shank comprises a reduced diameter threaded portion threadedly connected to receiving threads of the insert.

19. An arrow, comprising:

an arrow shaft having a first end and a first end wall;
