Description

BACKGROUND

Field

Embodiments of the present invention relate generally to a lacrosse head with an offset; and more specifically to a lacrosse head with a flush connection system.

Background

A lacrosse stick is a key piece of equipment for lacrosse players. Lacrosse sticks are used for offensive moves, such as cradling, catching, picking up, passing, and shooting a lacrosse ball, as well as for defensive moves, such as hitting an opponent's stick. Lacrosse sticks generally include a shaft and a head. A lacrosse head that is offset from the axis of the shaft allows for increased speed and accuracy when shooting or passing the ball, and also allows for increased control and ball retention when cradling the ball. However, lacrosse organizations have regulations for lacrosse sticks, including that the lacrosse stick be relatively straight (i.e., the lacrosse stick may be laid flat on a tabletop with a substantial portion resting on the table and a distance from the tabletop to the bottom edge of the lacrosse head not exceeding a certain distance (e.g., 2.75 inches)). This regulation indirectly limits the amount of offset permitted in a regulation lacrosse stick. Previous connection systems between a lacrosse head and a shaft further limit the amount of offset, thus preventing players from using the maximum benefit of an offset lacrosse head that would be permitted by the regulations.

DETAILED DESCRIPTION

The present invention will now be described in detail with reference to embodiments thereof as illustrated in the accompanying drawings, in which like reference numerals are used to indicate identical or functionally similar elements. References to “one embodiment”, “an embodiment”, “an example embodiment”, etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.
The term “invention” or “present invention” as used herein is a non-limiting term and is not intended to refer to any single embodiment of the particular invention but encompasses all possible embodiments as described in the application.
The following examples are illustrative, but not limiting, of the present invention. Other suitable modifications and adaptations of the variety of conditions and parameters normally encountered in the field, and which would be apparent to those skilled in the art, are within the spirit and scope of the invention.
Lacrosse sticks are used extensively during a game of lacrosse (e.g., to cradle, catch, pick up, pass, and shoot a lacrosse ball, or to hit an opponent's stick). Lacrosse sticks generally include a shaft and a head. A lacrosse head that is offset from the axis of the shaft (i.e., the bottom edge of the lacrosse head is spaced from the axis of the shaft) allows for increased speed and accuracy when shooting or passing the ball, and also allows for increased control and ball retention when cradling the ball, because it maximizes the distance the ball sits from the axis of the shaft. However, lacrosse organizations have regulations for lacrosse sticks that may limit this offset. For example, the NCAA men's lacrosse rules require lacrosse sticks to be relatively straight, which is defined as a lacrosse stick that may be laid flat on a tabletop with a substantial portion resting on the table and such that a distance from the tabletop to the bottom edge of the lacrosse head does not exceed 2.75 inches.
Other considerations have also limited this offset in previous lacrosse sticks. For example, during play, both the shaft and the head of a lacrosse stick repeatedly experience high forces, for example, from scooping a ball off the ground or being checked by an opponent's stick, which may loosen or crack the head or lead to separation of the head from the shaft. Accordingly, the connection of the head to the shaft should be secure to reduce these incidents. In light of these concerns, lacrosse sticks included connection systems with material that completely surrounded the shaft (i.e., an external stability element). Such external stability elements included material on the top surface of the shaft. Those of ordinary skill in the art would have expected a connection system without material over the top surface of the shaft to be inadequate in securing the head to the shaft and would have expected a lacrosse stick with such a connection system to frequently experience loosening, cracking, or separation of the head. Thus, previous connection systems between a lacrosse head and a shaft included material over the top of the shaft and further limited the amount of offset, which prevented players from using the maximum benefit of an offset lacrosse head that would be permitted by the regulations.
The embodiments described herein provide a connection system that provides the maximum allowable offset while maintaining a secure connection between the lacrosse head and the shaft. For example, the connection system allows the top side of the head (i.e., the side facing down in FIG. 2) and the shaft to be flush with each other. Accordingly, the distance between the top surface of the shaft and the bottom edge of the head (i.e., opposite the top side (facing up in FIG. 2)) may be the maximum allowable distance of 2.75 inches, which facilitates the maximum allowable offset.
In some embodiments, a lacrosse stick 10, as shown, for example, in FIG. 1, includes a shaft 20 and a head 30. In some embodiments, shaft 20 includes a top surface 22, an interior 24, and a bottom portion 26. Shaft 20 may have a cross-section height 21 (see FIG. 3) and a length suitable for a lacrosse stick (e.g., short sticks, long sticks, or goalie sticks). In some embodiments, shaft 20 has an octagonal cross-section. Other cross-sections may also be used, such as hexagonal, teardrop, oval, etc. In some embodiments, shaft 20 is hollow.
In some embodiments, head 30 includes a scoop 32, a pair of opposing sidewalls 34, a ball stop 36, and a throat 40. Scoop 32, sidewalls 34, and ball stop 36 may have a variety of designs. In some embodiments, throat 40 is configured to receive shaft 20. In some embodiments, throat 40 includes a top surface 42. In some embodiments, top surface 42 of throat 40 is flush with top surface 22 of shaft 20. In some embodiments, top surface 22 of shaft 20 is above top surface 42 of throat 40. In some embodiments, top surface 42 defines a gap 44. In some embodiments, top surface 22 of shaft 20 fills in gap 44 of top surface 42. In some embodiments, shaft 20 is visible through gap 44.
In some embodiments, throat 40 extends from a first end 46 to a second end 48. In some embodiments, first end 46 is the farthest point from ball stop 36. In some embodiments, second end 48 is closest to ball stop 36. In some embodiments, second end 48 is adjacent to ball stop 36. In some embodiments, gap 44 extends from first end 46 to second end 48. In some embodiments, gap 44 is wider at first end 46 than at second end 48, as shown, for example, in FIG. 9. In some embodiments, top surface 22 of shaft 20 fills in gap 44 so that top surface 22 of shaft 20 is flush with top surface 42 of throat 40. In some embodiments, top surface 42 is the highest portion of head 30. In some embodiments, no portion of head 30 extends above top surface 22 of shaft 20, as shown, for example, in FIG. 8. In some embodiments, this configuration allows lacrosse stick 10 to take advantage of the maximum allowable offset.
Lacrosse organizations may have regulations for dimensions of lacrosse sticks, including a distance 12 (see FIG. 2) from a top surface of a lacrosse stick 1 to a bottom portion of a lacrosse head. For example, the maximum allowable distance 12 may be 2.75 inches. A simple test 15 may be performed to check whether lacrosse stick 1 is compliant with these regulations. As shown in FIG. 2, lacrosse stick 1 may be placed on a flat surface 16, such as a table. To determine whether the regulation is met, the distance between flat surface 16 and the bottom portion of lacrosse stick 1 can easily be determined, which is equivalent to distance 12. Thus, according to the regulation, distance 12 must be within the maximum allowable distance (e.g., 2.75 inches).
Existing lacrosse heads have a material (often emblems, badges, etc.) at the throat disposed above the top surface of the shaft. This may limit the offset (i.e., the distance between the axis of the shaft and the bottom portion of the lacrosse head) that can be achieved by the lacrosse stick because the material will be part of distance 12. For example, as shown in FIG. 3, lacrosse stick 1 and lacrosse stick 10 may have shafts with an equal cross-section height 21 (e.g., 1.07 inches), as well as an equal distance 12 (i.e., from the top surface to the bottom surface) (e.g., 2.75 inches). However, lacrosse stick 1 and lacrosse stick 10 do not have an equal offset 14 because a portion of the head of lacrosse stick 1 is above the shaft.
In contrast, in certain embodiments, in lacrosse stick 10, top surface 42 of throat 40 is the top surface of lacrosse head 30. Because top surface 42 is flush with top surface 22 of shaft 20, lacrosse stick 10 provides the maximum allowable offset 14 (i.e., maximum allowable distance 12 minus half of the cross-section height 21 of the shaft) between the axis of shaft 20 and bottom edge 35 of head 30. For example, if lacrosse stick 1 and lacrosse stick 10 are both at the maximum allowable distance 12 of 2.75 inches and have a shaft cross-section height 21 of 1.07 inches, lacrosse stick 1 may have an offset 14 of 1.95 inches whereas lacrosse stick 10 may have an offset of 2.215 inches because lacrosse stick 10 does not have any material in head 30 above top surface 22 of shaft 20. This greater offset allows for increased speed and accuracy when shooting or passing the ball.
In some embodiments, as shown, for example, in FIGS. 4-6, lacrosse head 30 includes a connector 50. In some embodiments, connector 50 is disposed within throat 40. In some embodiments, throat 40 is configured to receive shaft 20 and connector 50 is configured to be inserted into interior 24 of shaft 20. In some embodiments, shaft 20 is disposed between throat 40 and connector 50.
In some embodiments, connector 50 comprises a prong or projection that extends from second end 48 within throat 40. For example, connector 50 may be a cantilevered projection that is supported at second end 48 of throat 40 and is unsupported at an opposite end of connector 50. In some embodiments, connector 50 extends beyond first end 46 of throat 40. In some embodiments, connector 50 extends to first end 46 of throat 40. In some embodiments, connector 50 does not extend as far as throat 40 (i.e., connector 50 may have a length that is less than the distance between first end 46 and second end 48).
In some embodiments, connector 50 is monolithic with throat 40. In some embodiments, connector 50 is monolithic with head 30. Thus, head 30 (including throat 40) and connector 50 may be a unitary component. In some embodiments, connector 50 is rigid. In some embodiments, connector 50 is co-molded with throat 40 and/or head 30. In some embodiments, connector 50 is integrally molded with throat 40 and/or head 30. Thus, in some embodiments, the connection system is integrated into throat 40 of head 30. In some embodiments, connector 50 is not a fastener (e.g., screw, bolt, etc.). In some embodiments, connector 50 is sufficient to withstand forces experienced during competitive lacrosse to securely hold head 30 on shaft 20.
In some embodiments, throat 40 has an interior shape that corresponds to the cross-sectional shape of shaft 20 (e.g., octagonal) (see FIG. 6). In some embodiments, a portion of connector 50 corresponds to a shape of interior 24. In some embodiments, the bottom surface 56 of connector 50 corresponds to a shape of interior 24. In some embodiments, the bottom surface 56 of connector 50 forms three or more sides of an octagonal shape. Accordingly, when shaft 20 and head 30 are attached, connector 50 is disposed within shaft 20 and shaft 20 is disposed within throat 40.
In some embodiments, the top of connector 50 is flat. In some embodiments, connector 50 has a width that is the same as the width of interior 24 of shaft 20. In some embodiments, connector 50 has a width that is at least 90% of the width of interior 24 of shaft 20.
In some embodiments, connectors may have a different shape than connector 50 shown in FIGS. 4-6. For example, in some embodiments, as shown in FIG. 10, a lacrosse head 130 includes a throat 140 with a connector 150. Throat 140 may have a top surface 142 that defines a gap 144. Throat 140 may be configured to receive shaft 20 such that top surface 142 is flush with top surface 22 of shaft 20 and shaft 20 fills gap 144. Connector 150 may be configured to be inserted into shaft 20. The bottom of connector 150 may correspond to a shape of interior 24. The top of connector 150 may have a shape that corresponds to the shape of the bottom of connector 150, in contrast to the top of connector 50, which is flat.
As another example, as shown in FIG. 11, a lacrosse head 230 includes a throat 240 with a connector 250. Throat 240 may have a top surface 242 that defines a gap (not shown). Throat 240 may be configured to receive shaft 20 such that top surface 242 is flush with top surface 22 of shaft 20 and shaft 20 fills the gap. Connector 240 may be configured to be inserted into shaft 20. The bottom of connector 250 may correspond to a shape of interior 24. Connector 250 may be T-shaped. In some embodiments, the top of connector 250 may extend to the top of interior 24 of shaft 20. Other variations of connectors may also be used.
In some embodiments, connector 50 comprises a hole 55 configured to receive a fastener (e.g., screw, bolt, etc.), such as a screw 60 (see FIG. 7). In some embodiments, connector 50 comprises more than one hole 55 (e.g., two holes 55). In some embodiments, as shown in FIG. 5, throat 40 comprises a hole 45 configured to receive a fastener (e.g., screw 60). In some embodiments, throat 40 comprises more than one hole 45 (e.g., two holes 45). In some embodiments, hole 45 is disposed in a bottom portion of throat 40.
As shown in FIG. 7, shaft 20 may also comprise a hole 25 configured to receive a fastener (e.g., screw 60). In some embodiments, shaft 20 comprises more than one hole 25 (e.g., two holes 25). In some embodiments, hole 25 is disposed in bottom portion 26 of shaft 20. In some embodiments, holes 45, holes 25, and holes 55 are aligned with each other. In some embodiments, one or more screws 60 are inserted through holes 45, holes 25, and holes 55 to secure head 30 to shaft 20. In some embodiments, holes 45, holes 25, and holes 55 have the same diameter d. In some embodiments, diameter d of holes 45, holes 25, and holes 55 is less than the width D of the threads of screws 60. When screws 60 twist into head 30, the material of throat 40 and connector 50 (e.g., plastic) deforms around the thread to create a secure fit.
Various embodiments described herein provide a connection system that facilitates a maximum allowable offset in a lacrosse stick, which may result in increased speed and accuracy, for example, when shooting a ball. At the same time, strength and rigidity of the lacrosse stick is maintained. Further variations of the embodiments described above may also be provided.
