FIELD OF THE INVENTION [0001]The present invention relates to sports equipment and, more particular, to handles and shafts of sports equipment. BACKGROUND OF THE INVENTION [0002]Lacrosse shafts are connected to lacrosse heads and are gripped by a user to allow the user to carry a ball and/or manipulate the shaft to cause the ball to be ejected from a lacrosse head to a desired location away therefrom, e.g., to pass the ball to another player or shoot at a goal. Various alterations to the standard lacrosse shaft have been attempted to increase the efficiency of throwing and/or catching the lacrosse ball using the lacrosse head. However, standard lacrosse shafts continue to have a continuous shape from end to end, sometimes changing in circumference, but not shape. For example, a traditional lacrosse shaft may have a continuous octagonal shape. Other shafts have been known to have a cross-sectional shape formed an "I", or to have a cross-sectional shape of a square having projections on opposite sides of the square. [0003]Thus, a need exists for improved lacrosse shafts to aid a user in throwing and/or catching a lacrosse ball using a head attached to such shafts. SUMMARY OF THE INVENTION [0004]The present invention provides, in a first aspect, a sports shaft which includes an elongated body, a first gripping notch, and a second gripping notch. The first gripping notch is located on a first side of the body. The second gripping notch is located on a second side of the body opposite the first side. The first notch and the second notch are located at positions along a longitudinal dimension of the body to receive hands of a user during operation. BRIEF DESCRIPTION OF THE DRAWINGS [0005]FIG. 1 is a perspective view of a sports shaft in accordance with the present invention; [0006]FIG. 2 is a side elevational view of the sports shaft of FIG. 1; [0007]FIG. 3 is a bottom elevational view of the sports shaft of FIG. 1; [0008]FIG. 4 is a top elevational view of the sports shaft of FIG.1; [0009]FIG. 5 is a cross sectional view of a portion of the sports shaft of FIG. 1 taken along lines 5-5; [0010]FIG. 6 is a cross sectional view of a portion of the sports shaft of FIG. 3 taken along lines 6-6; and [0011]FIG. 7 is a cross sectional view of a portion of the sports shaft of FIG. 4 taken along lines 7-7. DETAILED DESCRIPTION OF THE INVENTION [0012]In accordance with the principles of the present invention, a sports shaft is provided. [0013]In an exemplary embodiment, a sports shaft 10 (e.g., a lacrosse stick shaft) includes a body portion 20 having a first end 30 and a second end 40. Body 20 has a cross sectional area having an octagonal shape in the vicinity of first end 30, second end 40 and a central portion 50, as depicted in FIGS. 2 and 5. Ends 30 and 40 may have any shape (e.g., an octagonal shape) which is configured (e.g. shaped & dimensioned) to allow shaft 10 to engage with, and attach to, a sports head 5 (e.g., a lacrosse stick head). [0014]As depicted in FIGS.1-4, body 20 may include a first gripping notch 110 and a second gripping notch 150 on opposite sides of body 20. For example, notch 110 may include a notch central portion 115 and inclined portions 120 and 125. Body 20 may also include an outer surface 25 of a topside 200, which may be connected to notch central portion 115 by inclined surfaces 120 and 125. Also, a bottom side 300 may include an outer surface 325 which may be connected to a notch central portion 310 of notch 150 by inclined portions 320 and 315, as illustrated in FIG. 4. Body 20 may also include opposite side portions 400 and 410 along with connecting portions 420, 430, 440 and 450 as depicted in the octagonal cross section depicted in FIG. 5. [0015]Also, gripping notch 110 and second gripping notch 150 are configured (e.g., shaped and dimensioned) such that a user may grasp body 20 to allow manipulation thereof by the user. For example, notch 110 and notch 150 may have shapes (FIGS. 6-7) different than body 20 in the vicinity of first end 30, second end 40 and central portion 50. Notch 110 and notch 150 may be six-sided with outer surface 325 and outer surface 25 being relatively flat in the vicinity of notch central portion 310 and notch central portion 115, which may be substantially parallel to outer surfaces 25 and 325, respectively. Such six-sided figures (FIGS. 6-7) may be formed by the removal of a portion of body 20 which includes outer surface 25 and connecting portions 420 and 450 to result in notch central portion 115. Also, the removal of outer surface 325 and connecting portions 430 and 440 may form notch central portion 310 as is shown in FIG. 7. Such removal may be performed by sanding, cutting, or otherwise changing the shape of a sport shaft formed in an octagonal shape. Alternatively, such a sport shaft (e.g., sport shaft 10) may be molded, cast, forged or otherwise originally formed in the shape depicted in FIGS. 1-7. [0016]The inclined surfaces (e.g., inclined portions 120, 125, 315, 320) may be transition zones between the outer surfaces (e.g., outer surfaces 25 of top side 200 and outer surface 325 of bottom side 300) depicted in FIG. 5 versus the notch central zones (e.g., notch central zones 115 and 310) depicted in FIGS. 6 and 7. For example, the transition zones (cross sections not shown) may be eight-sided, but may have different cross sectional areas than that depicted in FIG. 5, with the connecting portions differing in height relative to that depicted in FIG. 5. [0017]Notches 110 and 150 may be gripped by a user (e.g., a lacrosse player) to allow shaft 10 to be held during operation, such as when throwing or catching a ball during a lacrosse game. The notches alter the shape (e.g., reduce the width) of shaft 10 such that the user may more easily grip first notch 110 and second notch 150 than the remainder of body 20 of shaft 10. For example, altering the shape of the shaft such that it has a reduced thickness in the area of the notches allows a user to easily orient his or her grip on the shaft and more comfortably utilize a lacrosse stick with better orientation. Further, by allowing a user to more tightly grip a lacrosse stick, more leverage may be applied such that the user may cause a ball to be thrown more quickly and accurately. Further, the reduced shaft thickness may also allow a user having smaller hands to utilize a standard sized lacrosse stick. The shape of the notches may also be more comfortable to a user's hand than a standard lacrosse shaft, for example. [0018]Also, gripping notches 110 and 150 may be located off set from a centerline 21 (i.e., a point equally distant to ends 30 and 40) along body 20 such that gripping notch 150 is further from centerline 21 than gripping notch 110 is relative to centerline 21. For example, gripping notch 150 may be located closer to head 5 than gripping notch 110 is relative to end 40. Shafts may also be formed of different lengths and the notches may be located at various points depending on the length of a particular shaft. For example, a defensive lacrosse player often uses a longer shaft than an offensive player. An offensive player may use the shaft depicted in the figures while a defensive player may use a shaft which is longer and which has the notches (e.g., notches 110 and 150) located further from a lacrosse head (e.g., head 5) than that depicted for shaft 10. For example, a mid-point 22 between notches 110 and 150 is located at a point closer to head 5 than centerline 21 as depicted in the figures. In contrast, a shaft (not shown) for a defensive player may have a center point closer to an end (e.g., end 40) opposite a head (e.g., head 5) then a centerline (e.g., centerline 21) thereof. Also, although the sports shaft depicted in the figures has notch 110 located on a same side of sport shaft 10 as a front of the lacrosse head depicted, the lacrosse head could be rotated such that notch 110 is located on an opposite side relative to the front of the lacrosse head while notch 310 could be located adjacent the front side of the lacrosse head. [0019]It will also be understood by one skilled in the art that notches 110 and 150 could be formed of any shape which is easily grasped or gripped by a user and is narrower than remaining portions of body 20. It will also be understood by one skilled in the art that the above described transition zones could be formed at any angle which is comfortable to the hand of a user and which tapers between the outer surfaces and center of the notched zones described above. It will also be understood by one skilled in the art that sport shaft 10 could be connected to any number of sports equipment heads (e.g., a hockey blade) which may be utilized in a manner similar to a lacrosse stick and in which a reduced diameter at hand holding portions thereof is desirable. Also, it will be understood that shaft 10 could be formed of any shape between the notches described above which is convenient to manufacture, promotes easy gripping. Further, it will be understood by one skilled in the art that body 20 could include notch 110 or notch 150, instead of both notches, while still promoting easy gripping by a user and promoting the use of a sports head such as a lacrosse stick head with body 20.
