Abstract

A reinforced archery arrow shaft includes a tubular core, with an attached two-part sleeve either covering the core, or disposed inside the core as a liner. The core may include carbon therein. The sleeve includes at least one higher-density front section formed from a fabric material, which is wrapped around and affixed to the core. The sleeve also includes a lower-density rear section wrapped around and affixed to the core behind the front section. The sleeve fabric may have a decorative design or pattern on the exterior surface thereof. The higher density of the front section provides front-of-center weight distribution in the finished arrow shaft. Optionally, accessories may be attached to the arrow shaft to form an arrow.

Claims

1. An arrow shaft, comprising:

a hollow tubular core which is adapted to be formed into an arrow shaft, said hollow core comprising carbon;

a two-part sleeve, where said sleeve either covers the core externally and is affixed to the core, or is provided as a liner disposed inside of the core and affixed thereto;

wherein a first part of the sleeve is disposed toward the front of the arrow shaft and comprises a first sleeve section formed of a fabric material and having a first density, and a second part of the sleeve is disposed toward the rear of the arrow shaft and comprises a second sleeve section which is less dense than the first sleeve section, whereby a front portion of the arrow shaft weighs more per inch than a rear portion thereof;

and

an adhesive resin material associated with the sleeve;

wherein the resin helps to adhere the sleeve to the core.

2. The arrow shaft of claim 1, wherein the shaft has a constant inside diameter and a constant outside diameter throughout the length thereof.

3. The arrow shaft of claim 1, wherein the sleeve is disposed outside of the core.

4. The arrow shaft of claim 3, further comprising an outer casing disposed outside of the sleeve and affixed thereto, whereby the sleeve is sandwiched between the core and the outer casing.

5. The arrow shaft of claim 1, wherein the sleeve is disposed inside of the core.

6. The arrow shaft of claim 1, wherein the first sleeve section has a design or pattern thereon.

7. The arrow shaft of claim 1, wherein the exterior of the two-part sleeve is treated to form a smooth surface on an exterior surface thereof.

8. The arrow of claim 1, wherein said resin material is selected from the group consisting of urethanes, varnishes, lacquers, epoxies, paints, and powder coatings.

9. An arrow, comprising:

a hollow tubular core;

a two-part sleeve where said sleeve either covers the core externally and is affixed to the core, or is provided as a liner disposed inside of the core and affixed thereto, the core and sleeve cooperating to define an arrow shaft, wherein a first part of the sleeve is disposed toward the front of the arrow shaft and comprises a first sleeve section formed of a fabric material and having a first density, and a second part of the sleeve is disposed toward the rear of the arrow shaft and comprises a second sleeve section which is less dense than the first sleeve section, whereby a front portion of the arrow shaft weighs more per inch than a rear portion thereof;

an adhesive resin material associated with the two-part sleeve; and

at least one auxiliary attachment connected to said arrow shaft, said auxiliary attachment selected from the group consisting of arrow heads, fletching, and nocks.
