Abstract

A vane, for a projectile such as an archery arrow, including a ribbon strip having a leading ribbon edge that is twisted to induce spin of the projectile during its flight. The vane can include a base that mounts to a projectile surface. The ribbon strip can extend upward from the base and can be semi-rigid but flexible. The ribbon strip can include an intermediate portion spaced a distance from and free from attachment to the projectile surface so as to form a gap under the intermediate portion. The ribbon strip can include a second ribbon end that is attached to the base rearward of the first end. It also can include a fin that extends upward from the base within a gap between the ribbon strip and base. The ribbon strip alternatively can include a cantilevered second ribbon end that is free from attachment to the base and projectile.

Claims

1. A vane configured to mount to a projectile, the vane comprising:

a base including an upper base surface and a lower base surface configured to mount to a surface of a projectile; and

a flexible ribbon strip extending upward from the base, the ribbon strip having a leading ribbon surface and a lower ribbon surface, the ribbon strip including a first ribbon end joined with the base, a second ribbon end distal from the first ribbon end, and an intermediate ribbon portion extending rearward from the first ribbon end toward the second ribbon end, the intermediate ribbon portion separated from the base with an opening defined therebetween, the ribbon strip including a twist integrally formed therein,

wherein the ribbon strip includes a ribbon thickness between the leading ribbon surface and the lower ribbon surface,

wherein the ribbon strip includes a first edge on a first side of the ribbon strip and a second edge on an opposing second side of the ribbon strip, the first edge and the second edge separated by a ribbon width that is greater than the ribbon thickness,

wherein the first edge faces forward adjacent the first ribbon end,

wherein the first edge faces laterally outward in the intermediate ribbon portion,

wherein the first edge faces forward, adjacent the second ribbon end,

whereby the ribbon strip is configured to induce spin to the projectile during flight of the projectile.

2. The vane of claim 1, comprising:

a first pillar extending from the upper base surface to the lower ribbon surface within the opening.

3. The vane of claim 2,

wherein the first pillar includes a curved forward edge and a curved rearward edge.

4. The vane of claim 2,

wherein the first pillar is disposed at an offset angle relative to a longitudinal axis of the vane.

5. The vane of claim 4,

wherein the offset angle is between 0°

and 20°

.

6. The vane of claim 5,

wherein the offset angle is between 1°

and 10°

.

7. The vane of claim 2, comprising:

a second pillar rearward of the first pillar, extending from the upper base surface to the lower ribbon surface within the opening.

8. A vane configured to mount to a projectile, the vane comprising:

a base configured to mount to a surface of a projectile; and

a ribbon strip extending upward from the base and including an intermediate ribbon portion configured to be spaced a distance from the surface of the projectile, the ribbon strip including a leading ribbon surface that twists from a first lateral direction, to an upward direction to an opposing second lateral direction, between the first ribbon end and a distal, second ribbon end of the ribbon strip,

wherein the ribbon strip includes a forward ribbon end and a rearward ribbon end, both commonly attached to the base, but separated by at least one opening along a longitudinal axis of the base,

whereby the ribbon strip is configured to induce spin to the projectile during flight of the projectile.

9. The vane of claim 8,

wherein the base includes a first base end and a second distal base end,

wherein the base includes a longitudinal axis having a first side and an opposing second side,

wherein the leading ribbon surface faces outward from the first side in the first lateral direction adjacent the first base end,

wherein the leading ribbon surface faces outward from the second side in the opposing second lateral direction adjacent the second base end.

10. The vane of claim 8,

wherein the base includes a lower base surface,

wherein the ribbon strip includes a ribbon edge,

wherein the ribbon edge twists in a helical manner with the ribbon from a rearward facing direction to the first lateral direction, back to the rearward facing direction between the first and second ends of the ribbon strip.

11. A vane configured to mount to a projectile comprising:

a base mounted to a surface of the projectile; and

a ribbon strip extending upward from the base and including an intermediate ribbon portion spaced a distance from the base, the ribbon strip including a leading ribbon surface that is twisted rearward of a first ribbon end to a rearward ribbon end the ribbon strip including a first side edge and a second opposing side edge separated by a ribbon width in the intermediate ribbon portion, the ribbon strip including an upper surface and a lower surface, separated by a ribbon thickness, which is less than the ribbon width, between the first side edge and the second side edge, the first side edge and second side edge each facing laterally outward from a longitudinal axis of the base, the upper surface and lower surface facing in opposite lateral directions at the first ribbon end and at the rearward ribbon end,

whereby the ribbon strip is configured to induce spin to the projectile during flight of the projectile.

12. The vane of claim 11, comprising:

a first pillar extending upward from the base and joined with the lower surface between the first side edge and the second side edge of the ribbon strip,

wherein the first pillar is disposed adjacent the longitudinal axis.

13. The vane of claim 11, comprising:

a first pillar extending upward from the base and joined with the lower surface between the first side edge and the second side edge of the ribbon strip,

wherein the first pillar is disposed inward from each of the first side edge and the second side edge.

14. The vane of claim 12,

wherein the first pillar is distal from the first side edge,

wherein the first pillar is distal from the second side edge.

15. The vane of claim 12, comprising:

a second pillar separate and rearward from the first pillar, the second pillar extending upward from the base and joined with the lower surface between the first side edge and the second side edge of the ribbon strip,

wherein the second pillar is spaced from the first pillar and the rearward ribbon end.
