In order to provide enhanced performance from fletching, an integral or slidable stabilizer is operatively associated with an arrow shaft. The stabilizer in either form includes a plurality of radial vanes each of which imparts aerodynamic force to the shaft so as to cause the arrow to roll or 'spin' when the arrow is in flight. In the preferred embodiments of the invention, the radial vanes of the stabilizer have a cross section in the form of an airfoil to thereby induce the roll or 'spin.'

Bow launcher and arrow system

In order to ensure rapid and effective arrow shaft positioning, without interfering with intended flight trajectory, an arrow rest assembly includes a support for an arrow in proximity to a handle riser portion of a bow. The arrow support includes a body member disposed in a plane generally parallel to a plane defined by the bow and a bowstring on the bow. The body member has a surface for supporting a shaft of the arrow. It also is mounted to the handle riser portion of the bow. The body member has a pivot point spaced from the shaft supporting surface. The mounting is associated with the body member at the pivot point. With this arrangement the arrow rest assembly is such that the mounting accommodates pivotal movement of the body member within the plane of the body member about the pivot point from an arrow supporting position to an arrow passage position.

Arrow rest assembly

In order to provide enhanced performance from fletching, a stabilizer is operatively associated with an arrow shaft to be moveable from a launch position near the tip of an arrow at one end thereof to a flight position near the nock of the arrow at the other end thereof. The stabilizer includes a slide collar disposed on the shaft for sliding movement therealong and having a plurality of radial vanes each with a leading edge and a trailing edge as well as a reinforcing extension forwardly of the leading edges of the vanes and extending rearwardly at least to the trailing edges thereof. By limiting the stabilizer to sliding movement along the shaft from the launch position to the flight position, a bow having a riser may be provided with a launcher mounted on the riser to resiliently grip the stabilizer with the vanes forward of the riser during launch.
