DETAILED DESCRIPTION
Illustrative embodiments will now be described to provide an overall understanding of the described lacrosse-stick heads. One or more examples of the embodiments are shown in the drawings. Those of ordinary skill in the art will understand that the described lacrosse-stick heads can be adapted and modified to provide devices for other applications, and that other additions and modifications can be made to the described lacrosse-stick heads without departing from the scope of the present disclosure. For example, aspects, components, and/or features, of the embodiments can be combined, separated, interchanged, and/or rearranged to generate other embodiments. Such modifications and variations are intended to be included within the scope of the present disclosure.
FIG. 1 shows an exemplary lacrosse-stick head, and FIG. 2 shows a lacrosse stick including the exemplary lacrosse-stick head. As shown in FIG. 1, the exemplary lacrosse-stick head 10 includes a throat 20 and two sidewalls 40 and 50 extending outward from the throat and connected by a transverse wall 30. The sidewall 40 extends outward from a side surface 28 of the throat 20. One or both of the sidewalls 40 and 50 can include spaced-apart upper and lower arms, such as upper and lower arms 42 and 44 of the sidewall 40. The upper and lower arms 42 and 44 can form the extreme extents of the sidewall 40. As shown in FIG. 2, the head 10 can be attached to a lacrosse-stick handle 100 and a lacrosse-stick pocket 200 for receiving a lacrosse ball.
As shown in FIG. 1, the orientation of the head 10 can be described with pitch, roll, and yaw angles 12, 14, and 16 with respect to a coordinate system having mutually orthogonal x, y, and z axes 11, 13, and 15. The roll angle 14 refers to rotation about the longitudinal axis of the head 10, i.e. about the y axis 13, and the pitch and yaw angles 12 and 16 refer to rotations about the x and z axes 11 and 15. FIGS. 1 and 2 show an orientation of the head 10 in which the pitch, roll, and yaw angles 12, 14, and 16 are zero, and FIG. 3 shows an orientation of the head 10 in which the pitch and yaw angles 12 and 16 are zero and the roll angle is approximately 90 degrees.
FIGS. 3 and 4 illustrate features of the head shown in FIG. 1. As shown in FIGS. 3 and 4, the sidewall 40 (e.g., the upper and lower arms 42 and 44) and the side surface 28 of the throat 20 are sized, shaped, and positioned for stably rolling a lacrosse ball 300 along at least a portion of the length of the sidewall 40 and onto the side surface 28. The term “stably” as used herein can be understood to mean that the sidewall 40 and the side surface 28 are sized, shaped, and positioned to form a rolling path extending from the sidewall 40 to the side surface 28 for at least one pitch angle 12 of the head 10 in which the force of gravity restores a lacrosse ball to the rolling path if the lacrosse ball is displaced from the rolling path within a range of roll angles 14 of the head 10. The sidewall 40 and the side surface 28 can be sized, shaped, and positioned to form such rolling paths throughout a range of pitch angles 12 of the head 10. For example, in the embodiments shown in FIGS. 3 and 4, the sidewall 40 and the side surface 28 can form rolling paths for pitch angles 12 ranging from about −30 degrees to about 30 degrees and roll angles 14 ranging from about 60 degrees to about 120 degrees. Other embodiments can exhibit ranges of pitch and roll angles 12, 14 that are smaller than the ranges just described. Preferably, however, the size of the range of roll angles 14 should be at least approximately 30 degrees, and the size of the range of pitch angles 12 should be at least approximately 30 degrees to facilitate control of a lacrosse ball.
The range of pitch 12 and roll 14 angles of the head 10 for which the sidewall 40 and the side surface 28 can form the previously described rolling paths represents a relationship between the sidewall 40 and the side surface 28. As will be understood by those of ordinary skill in the art, the sidewall 40 and, separately, the side surface 28 can support a lacrosse ball over ranges of pitch and/or roll angles that can be different than those describing the rolling paths.
As shown in FIGS. 3 and 4, in one embodiment, the upper and lower arms 42 and 44 of the sidewall 40 can be sized, shaped, and positioned such that, for at least one pitch angle 12 of the head 10, the upper and lower arms 42 and 44 cooperate to simultaneously support a lacrosse ball throughout a range of roll angles 14 of the head. The upper and lower arms 42 and 44 can cooperate to simultaneously support a lacrosse ball throughout a range of such pitch angles 12. For example, in the embodiments shown in FIGS. 3 and 4, the upper and lower arms 42 and 44 can cooperate to simultaneously support a lacrosse ball for pitch angles 12 ranging from about −30 degrees to 30 degrees and roll angles 14 ranging from about 45 degrees to about 135 degrees. Other embodiments can exhibit ranges of pitch and roll angles 12, 14 that are smaller than the ranges just described.
As shown in FIGS. 3 and 5, the side surface 28 of the throat 20 can be sized, shaped, and positioned such that, for at least one pitch angle 12 of the head 10, the side surface 28 supports a lacrosse ball throughout a range of roll angles 14 of the head 10. The side surface 28 can support a lacrosse ball throughout a range of such pitch angles 12. For example, in the embodiments shown in FIGS. 3 and 4, the side surface 28 can support a lacrosse ball for pitch angles 12 ranging from about −30 degrees to about 30 degrees and roll angles 14 ranging from about 60 degrees to about 120 degrees. Other embodiments can exhibit ranges of pitch and roll angles 12, 14 that are smaller than the ranges just described.
As shown in FIG. 3, one or both of the sidewalls 40 and 50 includes a convex shape with respect to the longitudinal axis 13. For example, as shown in FIG. 3, the sidewall 40 curves inward towards the longitudinal axis 13.
As shown in FIGS. 1, 3, and 5, the side surface 28 of the throat 20 has a size and a shape substantially similar to the size and the shape of a portion of the lacrosse ball 300. The side surface 28 can include a convex shape with respect to the longitudinal axis 12, i.e., the side surface 28 can curve inward towards the longitudinal axis 13.
As shown in FIG. 1, the upper and lower arms 42 and 44 can be connected by one or more connecting portions 70. The connecting portions 70 can be sized, shaped, and positioned so as to not inhibit the upper and lower arms 42 and 44 from stably rolling a lacrosse ball along at least a portion of the length of the sidewall 40. For example, as shown in FIG. 3, the connecting portions 70 and the upper and lower arms 42 and 44 can be sized, shaped, and positioned for stably rolling a lacrosse ball 300 along the upper and lower arms 42 and 44 along substantially the entire length of the sidewall 40 without contacting the connecting portions 70. Also for example, as shown in FIG. 3, the connecting portions 70, the upper and lower arms 42 and 44, and the side surface 28 of the throat 20 can be sized, shaped, and positioned for stably rolling a lacrosse ball 300 along the upper and lower arms 42 and 44 along a portion of the length of the sidewall 40 and onto the side surface 28 without contacting the connecting portions.
As previously described, the sidewall 40, e.g., the upper and lower arms 42 and 44, is configured for stably rolling a lacrosse ball along at least a portion of the length of the sidewall 40. The portion can include at least one half of the length of the sidewall 40. The length of the sidewall can be measured from substantially the throat 20, e.g. the location near the throat 20 at which separate upper and lower arms 42 and 44 are first distinguishable, to substantially the transverse wall 30, e.g., to the location near the transverse wall 30 at which separate upper and lower arms 42 and 44 are last distinguishable. Other embodiments can exhibit portions that include larger lengths. For example, in some embodiments, the portion of the length can include substantially the entire length of the sidewall 40, i.e., the length of the sidewall 40 extending substantially from the throat 20 to substantially the transverse wall 30. Preferably, however, the portion of the length should be at least one half of the length of the sidewall 40 to facilitate control of a lacrosse ball.
As shown in FIG. 1, the upper and lower arms 42 and 44 are separated by a distance di. In some embodiments, such as the embodiment of FIG. 1, the distance di can vary over the length of the sidewall 40 and/or over the portion of the length of the sidewall 40 configured for stably supporting the lacrosse ball 300. As shown in the embodiment of FIG. 1, the upper and lower arms 42 and 44 are separated by a distance d1 near the middle of the sidewall 40 and by smaller distances d2 and d3 near the throat 20 and the transverse wall 30. Generally, the distance di is less than the diameter of a lacrosse ball 300. The distance di can range from approximately zero in some units, i.e., the distance at which separate upper and lower arms 42, 44 are first distinguishable, to nearly the diameter of a lacrosse ball 300.
As shown in FIG. 4, the pairs of upper and lower arms 42, 44 and 52, 54 can include bases 72, 74 and 72′, 74′ and rails 82, 84 and 82′, 84′ that extend in a direction substantially outward from and substantially perpendicular to the bases 72, 74 and 72′, 74′. The rails 82, 84 and 82′, 84′ can form grooves 56, 56′ for stably supporting the lacrosse ball 300. As shown in FIG. 4, the rails 82, 84 can include sufficient outward extents from the bases 72, 74 such that the lacrosse ball 300 can be stably rolled along the rails 82, 84 along a portion of the length of the sidewall 40, 50 without otherwise contacting portions of the sidewall 40, such as the connecting portions 70 shown in FIG. 1 and/or a lacrosse pocket disposed on the head 10, such as the lacrosse pocket 200 shown in FIG. 2.
As shown in FIGS. 1, 2, 3, and 5, the throat 20 can include a depression 24 in an upper surface 26 of the throat 20. The depression 24 is sized, shaped, and positioned for stably supporting the lacrosse ball 300. For example, in some embodiments, the depression 24 can be substantially concave in shape with respect to the upper surface 26, i.e., can curve inwards from the upper surface 26 towards an interior of the throat 20. The size and shape of the depression 24 is substantially similar to the size and the shape of a portion of the lacrosse ball 300, such that the lacrosse ball 300 can be stably supported on the depression 24. The depression 24 includes a diameter D that is less than or substantially equal to the diameter of the lacrosse ball 300. The depression 24 can include one or more cutouts 25 in the upper surface 26 of the throat 20.
FIGS. 5-7 show features of the lacrosse-stick head 10 shown in FIG. 1. As shown in FIGS. 5-7, the transverse wall 30 of the head 10 can include an upper edge 132, a lower edge 134 positioned to be adjacent a pocket 200 disposed on the head 10 (i.e., the lower edge 134 is positioned to be closer to the pocket 200 than the upper edge 132 for an orientation of the head 10 having pitch and roll angles 12 and 14 of zero), and one or more projections 165 that extend downward from the lower edge 134 in a direction away from the upper edge 132 towards a surface 500. The projections 165 are sized, shaped, and positioned for grabbing the lacrosse ball 300 from the surface 500 between the projections 165 and a pocket 200 disposed on the head 100. For example, as shown in FIG. 7, the projections 165 are sized, shaped, and positioned for grabbing the lacrosse ball between the projections 165 and a surface 210 of the pocket 200 that faces the surface 500. The interior surfaces 167 of the projections 165, i.e. the surfaces of the projections 165 facing a pocket 200, can together form a shape that is similar to a shape of a portion of a lacrosse ball 300.
The projections 165 can include a variety of shapes. For example, as shown in FIGS. 5-7, the projections 165 include substantially triangular shapes. Alternatively, the projections 165 can include substantially polygonal shapes (e.g. shapes having three or more sides), substantially oval shapes (e.g. circular and elliptical shapes), and/or substantially semi-oval shapes (e.g. semi-circular and semi-elliptical shapes).
As shown in FIG. 3, the projections 165 are separated by a distance Δ. Generally, the distance Δ is less than the diameter of the lacrosse ball 300. The projections 165 can extend substantially perpendicular to the lower edge 134 of the transverse wall and can include sufficient outward extents from the lower edge 134 to facilitate grabbing of the lacrosse ball 300. As shown in FIG. 3, one or more cutouts 170 can be made in the transverse wall 30 to form the projections 165.
In some embodiments, the head 10 can include one projection 165. In one such embodiment, the projection 165 can include a width (i.e. an extent in a direction perpendicular to the outward extent) ranging from approximately 10% of the diameter of the lacrosse ball 300.
In some embodiments, the head 10 can include three or more projections 165. In one such embodiment, the outermost of the projections 165 (i.e. the two projections that are adjacent only one other projection) can be separated by a distance □ ranging up to nearly 100% of the diameter of the lacrosse ball 300.
The lacrosse-stick heads described herein can be fabricated based on schemes known to those of ordinary skill in the art. The heads can be fabricated from one or more of a ceramic, a metal, a plastic (e.g. nylon and/or polypropylene), and a wood. In some embodiments, the components of the heads can be formed from similar or different materials. In some embodiments, the heads can be integrally formed from a single material. For example, the heads can be constructed from molded plastic, such as injection molded plastic.
As shown in FIG. 2, the head 10 can be coupled to a lacrosse-stick handle 100. In some embodiments, the head 10 can be formed separately from the handle 100 and can be attached to or otherwise disposed on the handle 100 based on schemes known to those of ordinary skill in the art. For example, as shown in the embodiments of FIGS. 1 and 2, the head 10 can include a handle-receiving aperture 22 that can extend through at least a portion of the throat 20 for inserting the head 10 onto the handle 100. The head 10 can be glued, molded, press-fit, or otherwise attached to the handle 100. Alternatively, the head 10 can be formed integrally with the handle 100 based on schemes known to those of ordinary skill in the art.
As shown in FIG. 2, the head 10 can be attached to a lacrosse-stick pocket 200. In some embodiments, the head 10 can include one or more pocket apertures 32 that can be disposed in one or more of the throat 20, the transverse wall 30, and the sidewalls 40, 50 for attaching the pocket 200 to the head 100. The pocket apertures 32 can be sized, shaped, and arranged to facilitate attachment of the pocket 200. The pocket 200 can include pockets known to those of ordinary skill in the art, such as, but not limited to, pockets formed from one or more of leather and string.
As will be understood by those of ordinary skill in the art, the diameter of the lacrosse ball 300 can vary based on prevailing sporting regulations (e.g., regulations for novices, recreational players, secondary school players, collegiate players, and professionals). As used herein, the term “lacrosse ball” includes balls that are suitable for playing lacrosse under prevailing sporting regulations.
As will be understood by those of ordinary skill in the art, the described lacrosse-stick heads are not limited to use with lacrosse balls. For example, the upper and lower arms 42, 44 can form a groove 56 in which the groove 56 and an adjacent side surface 28 of the throat 20 are sized, shaped, and positioned for stably rolling a ball along at least a portion of the length of the sidewall 40 and onto the adjacent side surface 28. Also for example, the one or more projections 165 can be sized, shaped, and positioned for grabbing a ball from a surface 500. The ball can include one or more of a lacrosse ball, a tennis ball, a baseball, a softball, a golf ball, a rubber ball, a round rock, and other balls.
Those of ordinary skill in the art will recognize or be able to ascertain many equivalents to the exemplary embodiments described herein by using no more than routine experimentation. Such equivalents are encompassed by the scope of the present disclosure and the appended claims. Accordingly, the appended claims are not to be limited to the embodiments described herein, can include practices other than those described, and are to be interpreted as broadly as allowed under prevailing law.
