US12442627 - Projectile stabilizers, projectiles with stabilizers, and methods of manufacturing

A projectile and stabilizer therefor are provided. The sliding stabilizer is used instead of fixed or glued tail feathers, vanes or other fletching as a means for stabilizing projectile flight. The invention improves current projectile technology with reduced assembly labor cost, the elimination of bow clearance issues, improved accuracy with the consistent production of the sliding stabilizer, easy replacement of the stabilizer in the field, and improved projectile storage. A sliding stabilizer is designed to slide along the shaft of a projectile and comprises a circumferentially extending wing and a plurality of fins. In use, the stabilizer is positioned at the front of the projectile prior to launch, and the projectile slides quickly through the stabilizer until secured at a stop position at or near the trailing end of the projectile. An annular arrow fletch and arrow stabilizer are also provided. The annular arrow fletch may be used for; stabilizing arrow flight, providing better clearance and functionality then conventional fixed glued tail feathers. A stabilizer may be used with light emitting diode arrow nocks. The stabilizer may improve arrow shaft stabilization technology with reduced assembly labor cost, the elimination of facial and or face mask interference issues providing more clearance, improved accuracy, repeatable production with the consistent injection mold production of the annular arrow fletch, easy replacement of the annular arrow fletch in the field, and improved arrow storage. An annular arrow fletch may incorporate a metallic contact point, which will work with all light emitting nocks. A design of an annular arrow fletch may be affixed to an arrow by an arrow nock and may comprise an annular wing, a central elongated cylindrical cylinder with a cap and a plurality of fins with micro-groves and a metal contact. In use, the annular arrow fletch is affixed at the aft end of the arrow by an arrow nock prior to launch.

The patent describes a sliding stabilizer for projectiles, which enhances flight stability and accuracy while reducing assembly costs and clearance issues. It includes features such as a circumferential wing and fins that promote rotation during launch, allowing for easy field replacement and improved storage.

Claim 1

An arrow including: a shaft, the shaft having an outside diameter, the shaft having a first end and a second end and defining a central axis and a stop proximate the second end; a tip at the first end of the shaft a stabilizer for the arrow placed upon the second end of the shaft, the stabilizer comprising a shaft receptacle that is less than the outside diameter of the prior to the shaft being received within the shaft receptacle, wherein the stabilizer includes a plurality of fins oriented with respect to the central axis such that the stabilizer encourages arrow rotation about the central axis when the arrow is launched, and wherein a breakaway coefficient of friction between an inner surface of the shaft receptacle and an outer surface of the shaft is above a rotational force that the stabilizer exerts on the shaft when the projectile is projected, the stabilizer further comprising a mating feature adapted to engage the stabilizer with the stop. a shaft, the shaft having an outside diameter, the shaft having a first end and a second end and defining a central axis and a stop proximate the second end; a tip at the first end of the shaft a stabilizer for the arrow placed upon the second end of the shaft, the stabilizer comprising a shaft receptacle that is less than the outside diameter of the prior to the shaft being received within the shaft receptacle, wherein the stabilizer includes a plurality of fins oriented with respect to the central axis such that the stabilizer encourages arrow rotation about the central axis when the arrow is launched, and wherein a breakaway coefficient of friction between an inner surface of the shaft receptacle and an outer surface of the shaft is above a rotational force that the stabilizer exerts on the shaft when the projectile is projected, the stabilizer further comprising a mating feature adapted to engage the stabilizer with the stop.
