Abstract
An arrow has a shaft and an arrowhead assembly. The shaft has two ends, with one end having a nock and the other end having a coupling. The arrowhead assembly has a point and a coupling. The shaft of the arrowhead couplings are designed so that the two components can removably couple to one another. An extension member is provided so as to lengthen the shaft and permit the operator to pull back further on the bow. The extension member has a shaft and two ends. Each end removably couples to the respective shaft and arrowhead couplings.
Description
- This application claims the benefit of provisional patent application, Ser. No. 61/293,947, filed Jan. 11, 2010.
- The present invention relates to arrows.
- Bow hunters use bows and arrows to shoot at game. Contemporary bows are of a compound design to increase the force applied to the arrow. In addition, contemporary bows have targeting equipment to increase the accuracy of the shot.
- Hunters use a variety of points or arrowheads, depending on the particular game that is being sought. For example, with an elk or a deer, a broadhead point is typically used. Other points are used for smaller game. Some broadhead points are large and inhibit a full drawing back of the arrow, as the arrowhead or point contacts the bow. In order to avoid damage to the bow by the point, the hunter will use less than a full draw of the arrow.
- A hunter could buy a longer arrow shaft, but this would only suit the use of that particular point, thus requiring the hunter to purchase and carry additional shafts. In general, bow owners travel light, carrying only a handful of arrows which are used with a variety of points. It is not practical for the hunter to have special elongated arrow shafts for a special point.
- An arrow comprises a shaft and an arrowhead assembly. The shaft has two ends, with one end having a nock. The other end has a shaft coupling. The arrowhead assembly has a point and a point coupling. The point coupling and the shaft coupling are capable of interacting so as to couple the arrowhead assembly to the shaft. An extension member has a shaft and first and second ends. The first end is removably coupled to the shaft coupling of the shaft, and the second end is removably coupled to the point coupling of the arrowhead assembly, wherein the arrow is elongated.
- In accordance with one aspect, the shaft coupling, the point coupling, the first end coupling and the second end coupling are threaded couplings.
-
FIG. 1 is a side view of an arrow. -
FIG. 2 is a side view of an extension member of the present invention, in accordance with a preferred embodiment. -
FIG. 3 is a side view of a male insert. -
FIG. 4 is an exploded view of a point, the extension member and an arrow shaft. -
FIG. 1 shows anarrow 11 of the type used by archers and bow hunters. Thearrow 11 has ashaft 13 with two ends. One end has anock 15, or notch, for receiving the bow string. Close to the nock are feathers, vanes or fletching 17. The other end of theshaft 13 has a female threaded fitting or coupling for receiving an arrowhead assembly, or point, 19. The arrowhead assembly has a point or tip at one end and a coupling at the other end for fitting to the shaft coupling. - The
arrow shaft 13 can come in several lengths, such as, for example, 28, 30 or 32 inches. The hunter or archer chooses the arrow length depending on how far back the bow is drawn; this correlates to arm length. A hunter with longer arms tends to draw the bow further and prefers a longer arrow. - The
arrow 11 is provided with anextension member 21 which effectively elongates the arrow between thepoint 19 and thenock 15. Theextension member 21 allows a hunter or archer to modify an arrow shaft to accommodate a broad arrowhead or point and allow a full draw of the arrow, without the point contacting the bow. Using a full draw enables the hunter to shoot more accurately and quickly, and without the need to worry about bow damage. - Referring to
FIG. 2 , theextension member 21 has ashaft 23 that is the same diameter as thearrow shaft 13. Theshaft 23 has afront end 25 and arear end 27. Thefront end 25 has a female threaded fitting 29 (shown in dashed lines inFIG. 2 ) that receives the male threaded fitting of the arrowhead orpoint 19. Therear end 27 has amale insert 31. - Referring to
FIG. 3 , themale insert 31 has aninterior end portion 33 and anexterior end portion 35. Theinterior end portion 33 hascircumferential grooves 37. The outside diameter of the interior end portion is such that an interference or friction fit is formed with the inside diameter of theshaft 23. Preferably, glue or adhesive is used to secure theinterior end portion 33 of themale insert 31 in theshaft 21. The glue enters thegrooves 33, which grooves assist in providing a tighter bond. - The
male insert 31 has acircumferential flange 39 located between the interior andexterior end portions flange 39 acts as a stop against theshaft 23, when the insert is pressed into the shaftrear end 27. - The
exterior end portion 35 emulates the threadedend 35 of a point 19 (seeFIG. 4 ). Theexterior end portion 35 has asmooth section 41 next to the flange and a threadedsection 43. Theexterior end portion 35 is received by the female fitting 29 in the front end of thearrow shaft 13. - The
shaft 23 can be made of the same material asarrow shafts 13, such as aluminum, fiber composites, plastic, etc. Theshaft 23 is several inches long, typically 2 to 4 inches. Theinsert 31 can be made of a variety of materials. In the preferred embodiment, theinsert 31 is made of aluminum. - An arrow can be easily modified or retrofitted with the
extension member 21, as shown inFIG. 4 . If the arrow is equipped with apoint 19, the point is unthreaded from the front end of thearrow shaft 13. Theextension member 21 is then fitted to thearrow shaft 13 by threading theinsert 31 threadedportion 43 into thefemale fitting 29 on the front end of thearrow shaft 13. Next, thepoint 19 is coupled to thefront end 25 of theextension member 21 by threading themale end 35 of the point into thefemale fitting 29 of the extension member. The arrow is now ready for use. - Removal of the
extension member 21 returns the arrow to its original length. - With the extension member, a hunter can be out hunting and carry arrows suitable for all points. When an enlarged point is to be used, which point might mar or damage the bow, the hunter merely equips the arrow with an extension member before putting on the enlarged point. If the hunter changes his mind, the extension member can be easily removed and returned to its original length and configuration.
- The foregoing disclosure and showings made in the drawings are merely illustrative of the principles of this invention and are not to be interpreted in a limiting sense.
