Arrow with nock and head alignment
First Claim
1. An arrow with self-aligning features for use in association with an arrow head, said arrow comprising:
- a shaft including a rounded polygonal shaft cross-section; and
a removable nock including a rounded polygonal nock cross-section matching the rounded polygonal shaft cross-section and adapted to engage and directly contact the shaft cross-section along the rounded polygonal cross-section, thereby preventing relative rotation therebetween based on engagement of the matching rounded polygonal shaft cross-section with the rounded polygonal nock cross-section;
wherein the shaft is adapted to extend from the removable nock to the arrow head.

Abstract
An arrow with self-aligning features allows a user to properly nock the arrow without resorting to manual alignment of the nock and fletchings. Engagement of a removable nock and shaft, each with a rounded polygonal cross-section, such as a reuleaux triangle, allow for a fixed relative angular position between the nock and the shaft without the use of an adhesive. This allows for proper position between the nock and index vane to ensure a more accurate path of the arrow during flight. Similarly, the reuleaux triangle cross-section of the shaft may engage an arrow head with a similar reuleaux triangle for accurate alignment between the shaft and the arrow head.

15. An arrow with self-aligning features comprising:
-
a shaft with a first end and a second end, said shaft including a first aperture at the first end and a second aperture at the second end, wherein the first aperture and the second aperture each comprise a reuleaux triangular shape; and a removable nock including a first extension with a reuleaux triangular cross-sectional shape matching the reuleaux triangular shape of the first aperture, wherein the first aperture is adapted to receive the first extension, thereby preventing relative rotational movement between the shaft and the nock based on the matching of the reuleaux triangular cross-sectional shape of the first extension with the reuleaux triangular shape of the first aperture. - View Dependent Claims (16, 17, 18, 19)

20. An arrow with self-aligning features for use with an archery weapon including a string, said arrow comprising:
-
a shaft including an end with a reuleaux triangular shaft cross-section; a plurality of fletchings attached to the shaft, at least one of said fletchings comprising an index vane; and a removable nock including a reuleaux triangular nock cross-section matching the reuleaux triangular shaft cross-section and adapted to directly engage the shaft along the reuleaux triangular shaft cross-section, and the nock further including a notch adapted to engage the string along a longitudinal length of the notch; wherein direct engagement of the reuleaux triangular shaft cross-section and the reuleaux triangular nock cross-section establishes a fixed relative angular position between the longitudinal length of the notch and the index vane. - View Dependent Claims (21, 22)
