Filed:

Oct 5, 2011

Appl. No.:

13/253507

Inventors:

Larry R. Griffith - Lake City MI, US
Anne-Marie Bebak - The Woodlands TX, US

Assignee:

The Bohning Company, Ltd - Lake City MI

International Classification:

F42B 6/06

US Classification:

473586

Abstract:

Disclosed is a vane that can be attached to an arrow shaft to provide substantial stabilization in arrow flight through increased drag and arrow shaft spin. Embodiments of the inventive vane do not significantly increase the weight of an arrow and/or create a high probability of clearance problems with bow components. The vane is approximately 3. 997 inches long and 0. 327 inches high including the base height. The vane fin is approximately 0. 28 inches high. Some embodiments may have a length approximately 2. 997 inches long. An advantage of some embodiments is that the vane may be applied to an arrow shaft in a helical fashion.

International Classification:

F42B 6/06

US Classification:

473585

Abstract:

Disclosed is a composite arrow vane for mounting to a projectile. The composite arrow vane is constructed of a composite material that includes a polymer matrix around structural elements. In some embodiments, the polymer matrix may be a thermoplastic polyurethane. The structural elements compounded into the polymer may be voids, hollow glass beads or just about any structure having a weight per unit volume that is less than the weight per unit volume of the polymer matrix. Advantageously, the composite material allows for reduced dimensions of the composite arrow vane because the increased tensile strength of the material allows for size reductions without significantly compromising vane performance. Similarly, the lighter weight per unit volume of the composite material as compared to a homogeneous polymer allows for increased flight speed of the projectile.

International Classification:

F42B 6/04

US Classification:

473575

Abstract:

A bowfishing arrow with a medium that receives a slider and allows the slider to traverse a substantial length of the arrow shaft. The slider can receive a fishing line and when being drawn, the slider allows the slider and fishing line to remain in front of the bow and, upon release, the slider traverses to the back of the arrow during flight but, the slider at all times remains in front of the bow.
