A lacrosse head including a sidewall having upper and lower rails and an optional cross member. At least one of the upper and lower rails and cross member are cored out to define a recess. The recess can be partitioned by multiple trusses into multiple individual voids. The voids can be of increasing depth, progressing from shallower to deeper depths from the bottom rail to the upper rail. The lower rail can be reinforced with additional trusses near the base or ball stop of the head to add strength and rigidity there. The density of the trusses and/or cross sectional area of material can be altered in the upper rail, lower rail and cross member to selectively alter stiffness in those components. The stiffness of these components can also vary to provide different position heads, for example, attack, midfield and defense heads, with selectively different stiffness and strength characteristics. |

1. A lacrosse head comprising:
a throat adapted to connect to a lacrosse handle; a base joined with the throat, the base including a ball stop, the ball stop extending from an upper ball stop rim to a lower ball stop rim; a scoop distal from the base; a first sidewall and a second sidewall, each extending from the base toward the scoop and joined with one another distal from the base at the scoop, each first and second sidewall being of an open frame construction, each first and second sidewall including an upper rail and a lower rail and a cross member extending between and joined with the upper rail and the lower rail, and a longitudinal axis extending from the ball stop toward the scoop, wherein at least one of the upper rail, lower rail and cross member is cored out to define a plurality of voids, wherein each of the plurality of voids opens toward an interior of the head, toward the longitudinal axis, wherein at least one void from the plurality of voids includes a first truss extending across the at least one void. |
