Abstract

A short archery arrow equipped with a sabot and a launching barrel therefor that may be used with either a regular bow or a crossbow. When in the form of a hunting arrow, the cutting blades alone provide all the required fletching action and the center of gravity of the arrow lies forwardly of the blades. The blades are preferably not sharpened when the arrows are used for target shooting. The sabots and launching barrels have interfitting tongue and groove formations which provide guidance action to the arrows. On leaving the launching barrel the sabots separate from the arrows due to wind resistance action on the sabots.

Claims

1. An archery arrow comprising a shaft having a point at one end and a nock on the opposite end and fletching consisting of blades located rearwardly of the center of gravity of the arrow, the trailing edges of two opposing blades being bent so as to induce axial spin in flight, and said arrow having a length not exceeding about 7 inches.

2. The archery arrow of claim 1, wherein said fletching blades are sharpened.

3. The archery arrow of claim 1, wherein there are four fletching blades.

4. A sabot for an archery arrow which travels with the arrow as unit until its guidance function ceases and separation therefrom occurs comprising a heel having an opening permitting the heel to slidably receive the shaft of an arrow and a plurality of parallel arrow guidance fingers extending from said heel.

5. The sabot of claim 4, wherein there is one pair of guidance fingers which spread apart when not restrained.

6. The combination of an archery arrow comprising a shaft with a point end and a nock end and having a plurality of fletching blades on its shaft and a sabot which travels with the arrow as a unit until its guidance function ceases and separation therefrom occurs comprising a heel portion which fits slidably on the arrow shaft and a plurality of arrow guidance fingers which extend from said heel along the arrow shaft in the direction of said point end.

7. In the combination of an arrow and a sabot as called for in claim 6, said plurality of fletching blades comprising four blades extending radially from the arrow shaft in approximately the two o'"'"'clock, four o'"'"'clock, eight o'"'"'clock and ten o'"'"'clock directions.

8. In combination, an archery arrow, a sabot on the arrow, and a barrel for launching the arrow with the sabot thereon;

said arrow comprising a shaft having a point end and a nock end and a plurality of fletching blades mounted thereon;

a sabot comprising a heel with an opening allowing it to fit slidably on said arrow shaft and a plurality of arrow guidance fingers extending along said shaft from said heel toward said point end; and

a launching barrel comprising elongated members having guidance formations which slidably engage at least portions of said guidance fingers.

9. The combination of claim 8, wherein said sabot has an interference fit with said arrow which suffices to prevent the sabot from falling off the arrow when no separating force is applied while the wind resistance action on said heel of said sabot causes said sabot to separate from said arrow when the arrow leaves the muzzle of said barrel.

10. The combination of claim 8, wherein said barrel guidance formations provide spaced opposing grooves and said sabot guidance fingers have ribs which interfit in said grooves.

11. The combination of claim 10, wherein said guidance fingers and said arrow shaft have interfitting, formations which prevent separation thereof when said guidance fingers engage said arrow shaft and are restrained from spreading apart, and wherein said guidance fingers include formations which engage said barrel guidance formations and restrain said guidance fingers from spreading.
