DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0024] Referring now to the figures which illustrate a lacrosse goalie head 10 in accordance with the present invention. The lacrosse goalie head 10 is preferably formed using an injection molding process, however, other processes such as structural foam molding or the like may also be utilized. The lacrosse goalie head 10 is preferably formed from a plastic material, however, other materials such as urethane, nylon, polyvinyl chloride, polyester, or a combination thereof may also be utilized. Various directional terms, such as top, bottom, upper, lower, outer, forwardly, inwardly, and rear are used herein to describe the head as illustrated in the drawings. However, it should be understood that these directional terms are not intended to be limiting and are only used for purposes of illustration.

[0025] Referring to the drawings, the present invention is directed to a lacrosse goalie head 10. The lacrosse goalie head 10 includes a transverse base cross member 12 at least a portion of which is generally linear, a transverse upper cross member 14 at least a portion of which is generally linear, sidewalls 16 and 18 interconnecting transverse base cross member 12 and transverse upper cross member 14 to form a generally skull-shaped frame having a front surface 17 and a back surface 19. Sidewalls 16 opposes sidewall 18 wherein each sidewall 16, 18 includes a generally nonlinear obtuse portion between the upper cross member 14 and base cross member 14 defining a smaller width profile lower section 20 (throat) and a larger width profile upper section 22 (scoop). The throat 20 has a width of about 6.5 inches (16.51 cm) and the scoop 22 a width of about 9.5 inches (41.91 cm). By virtue of the unique configuration of the head 10 keeping within regulated head surface area guidelines, a frame height of about 16.5 inches and scoop outer diameter width of about 12.15 inches and inner diameter width of about 10/2 inches can be achieved, which is significantly more than designs currently on the market.

[0026] A stick (not shown) can be attached to a stick receiving portion 24 which extends from base cross member 12 and includes spatially oriented cutouts 25 to reduce overall weight. A string web (not shown) can be attached to the rear portion of the head through string holes 26 in the sidewalls 16 and 18, transverse base cross member 12, and transverse upper cross member 14. There are a recessed sections 32, 34, 36 and 38 which are interconnected and extend along a back portion of the transverse base cross member 12, the transverse upper cross member 14 and sidewalls 16 and 18, respectively, and thus form a continuous recessed surface adjacent the back surface 17. The recessed sections 32, 34, 36 and 38 have the holes 26 spaced there along for the string web. A continuous rib 40 is defined about the perimeter of the head 10 adjacent the recessed sections 32, 34, 36 and 38 medially in the sidewalls 16 and 18, transverse base cross member 12 and transverse upper cross member 14. On an opposing side of the rib 40 are widening portions 42, 44, 46 and 48 of the transverse base cross member 12, the transverse upper cross member 14 and sidewalls 16 and 18, respectively.

[0027] In widening portion 44, there is also another recessed portion 54. The transverse upper cross member 14 provides for increased strength and rigidity leading to less unwanted ball deflection. This aids in weight reduction of the head 10 and lends to the overall weight and balance.

[0028] As can be seen in the side views FIG. 4 and FIG. 5, each of the sidewalls 16 and 18 include a uniquely designed open arcuate lattice structure 56 and 58, respectively, which each has a large end 66 and 68 adjacent the transverse base cross member 12 and terminates in a small end 76 and 78 more than midway in the respective sidewall 16 and 18. Each open arcuate lattice structure 56 and 58 is tapered from the large end 66 and 68 to the small end 76 and 78, respectively. The open arcuate lattice structures 56 and 58 not only lend to weight and balance but also to performance in the rigidity and dynamics of the overall design. As can be seen, the open arcuate lattice structure 56 and 58 are tapered from wider to narrow moving from the transverse base cross member 12 forward. The open arcuate lattice structure 56 and 58 structure is a preferred embodiment of the invention providing an opening in the sidewalls 16 and 18 for a more balanced head 10 with the required support, strength, and durability desired.

[0029] While a preferred embodiment of the invention is set forth above, it is contemplated some aspects of the design may be varied to still fall within the scope of the invention. For example, the number, size, or shape of the open arcuate lattice structure 56 and 58 openings might be varied foe men's, women's, or children's lacrosse.

[0030] Referring again to the sidewalls 16 and 18, open arcuate lattice structure 56 and 58, opening sizes range from 0.635 cm wide to 0.318 cm. A total greater open area of surface is provided by the current configuration.

[0031] The openings 26 required for stringing the webbing material are approximately 0.635 cm by 0.3175 cm. Accordingly, the total area of openings in each sidewall 16 and 18, including string holes and open arcuate lattice structure 56 and 58, spans about 40% of each entire sidewall 16 and 18.

[0032] The lattice-structure 56, 58 of the goalie head 10 located adjacent to the transverse base cross member 12 and stick receiving portion 24 has an open area of approximately 60%, with the solid structure through this area of approximately 40%. The open lattice-structure 56, 58 of the side walls 16, 18 results in a light weight structure, since excess material has been removed from a neutral axis of the side walls 16, 18 in this area. A finite element analysis of the goalie head 10 was employed to remove material to optimize the head 10.

[0033] The head side walls 16, 18 have a unique transition from where the sidewalls 16, 18 that are close to the the transverse base cross member 12 and stick receiving portion 24, i.e., in an area of the throat 20, are roughly perpendicular to the x-y plane 100 made by the string holes 26 and transitions to where the sidewalls 16, 18 are at roughly a 45 degree angle to the plane 100 in an area of the scoop 22. Structurally, this results in approximately 30% increase in (transverse) stiffness across the width of the head 10 compared to other available goalie heads.

[0034] The head side walls 16, 18 and their lattice-structure 56, 58 allow for improved stiffness in the (depth) direction perpendicular to the plane 100 (the depth is shown as the 2.5 dimension). The increased moment of inertia and section modulus of the goalie head 10 results in approximately 70% increase in stiffness in the depth direction compared to commercially other available goalie heads.

[0035] The material forming the lacrosse head 10 of the invention must have physical properties providing, inter alia, toughness, impact resistance, and limited flexibility as well as shatterproof qualities. A preferred material is a moldable polymer 97% Dupont ST-701 plastic mixed with 3% Graphene, creating an extremely stiff and durable head, while maintaining lighter weight. The lacrosse head 10 may be formed by injection molding of one or more similar synthetic polymeric materials.

[0036] The present invention provides increased control for a goaltender over incoming lacrosse balls and thereby increasing the goaltender's performance in defending a lacrosse goal. The above-described apparatus and manufacturing method, to one skilled in the art, is capable of being adapted for various purposes and is not limited to the following applications: lacrosse goalie heads, lacrosse heads in general, and other similar heads used in other sporting activities. The above-described invention can also be varied without deviating from the true scope of the invention. While particular embodiments of the invention have been shown and described, variations or alternate embodiments will occur to those skilled in the art. Accordingly, it is intended that the invention be limited only in terms of the appended claims.
