Abstract

An arrow includes an elongate shaft, a plurality of vanes located proximate a proximal end of the shaft, and a point located proximate a distal end of the shaft. The shaft may have a dimpled outer surface. The shaft may also or alternatively have an internal supporting structure.

Claims

1. An arrow comprising:

a hollow elongate shaft comprising at least one interior wall, wherein the interior wall intersects the shaft at a rounded edge, and wherein the elongate shaft comprises an outer wall and the interior wall comprises a plurality of interior walls comprising chord walls;

a plurality of vanes located proximate a proximal end of the shaft; and

a point located proximate a distal end of the shaft.

2. The arrow of claim 1, wherein the plurality of interior walls extend radially from a shaft axis.

3. The arrow of claim 1, wherein the plurality of interior walls comprise a first wall substantially concentric to the outer wall and a second wall connecting the first wall to the outer wall.

4. The arrow of claim 3, wherein the second wall comprises a plurality of second walls.

5. The arrow of claim 1, wherein the interior wall and the hollow shaft at least partially define a plurality of voids.

6. The arrow of claim 5, wherein the voids comprise at least one of a peripheral void and a central void.

7. An arrow comprising:

a hollow elongate shaft comprising an outer wall;

a support structure located within the shaft, wherein the support structure comprises;

an inner wall substantially concentric to the outer wall; and

at least one wall brace located between the outer wall and the inner wall;

a plurality of vanes located proximate a proximal end of the shaft; and

a point located proximate a distal end of the shaft.

8. The arrow of claim 7, wherein the shaft and the support structure comprise discrete elements.

9. The arrow of claim 7, wherein the support structure at least partially defines a plurality of voids.

10. The arrow of claim 9, wherein the voids comprise at least one of a peripheral void and a central void.

11. An arrow comprising:

a hollow elongate shaft comprising at least one interior wall, wherein the elongate shaft comprises an outer wall and the interior wall comprises a plurality of interior walls, and wherein the plurality of interior walls extend radially from a shaft axis, and wherein the plurality of interior walls comprise chord walls and intersect the shaft at rounded edges;

a plurality of vanes located proximate a proximal end of the shaft; and

a point located proximate a distal end of the shaft.

12. The arrow of claim 11, wherein the plurality of interior walls comprise a first wall substantially concentric to the outer wall and a second wall connecting the first wall to the outer wall.

13. The arrow of claim 12, wherein the second wall comprises a plurality of second walls.

14. The arrow of claim 11, wherein the interior wall and the hollow shaft at least partially define a plurality of voids.

15. The arrow of claim 14, wherein the voids comprise at least one of a peripheral void and a central void.
