ARROW WITH NOCK AND HEAD ALIGNMENT

Thu, 06 Apr 2017 08:00:00 EDT

An arrow with a non-circular central bore may allow for differential flexural rigidity in the shaft. A non-circular central bore, such as in the form of a bore with a rounded polygon, or more specifically a reuleaux triangle, may also provide self-alighting features when paired with a nock or arrowhead with similar shaped elements. This may allow a user to properly nock an arrow without resorting to manual alignment of the nock and fletchings. The central bore may extend along an entirety of the shaft, or only along a portion of the shaft. The non-circular central bore may be incorporated in an arrow shaft with a round exterior cross section, or with an arrow with a non-circular exterior cross section, such as in the form of a rounded polygon, or more specifically a reuleaux triangle.



ARROW WITH NOCK AND HEAD ALIGNMENT

Thu, 06 Apr 2017 08:00:00 EDT

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.



GOLF AID INCLUDING HEADS UP DISPLAY

Thu, 06 Apr 2017 08:00:00 EDT
