Patent ID: 7736252

Claim:
A lacrosse head, comprising: a throat portion having a stop member thereon; a scoop portion; a first sidewall extending a first distance from the throat portion to the scoop portion and defining a first sidewall longitudinal axis, the first sidewall comprising a first upper rail and a first lower rail, the first upper rail and the first lower rail separated by a first opening; and a second sidewall extending a second distance from the throat portion to the scoop portion and defining a second sidewall longitudinal axis the second sidewall comprising a second upper rail and a second lower rail, the second upper rail and the second lower rail separated by a second opening, wherein, for along at least half of the first distance, the first sidewall has a cross section taken perpendicularly to the first sidewall longitudinal axis wherein in the cross section: at least one of the first upper rail and the first lower rail includes two or more intersecting surfaces opposing each other and intersecting at an intersection point so as to define a hollow space open to atmosphere, in the at least one of the first upper rail and the first tower rail, the hollow space being open at distal ends of the two or more intersecting surfaces opposite to the intersection point, the hollow space having a cross-sectionally area measured within a line connecting the distal ends of the two or more intersecting surfaces and bounded by the two or more intersecting surfaces, and the cross-sectional area of the hollow space being at least half of the cross-sectional area of the two or more intersecting surfaces.
