## Abstract

A lacrosse stick head frame has elongated side walls extending outwardly from each other at a throat portion to a transverse top wall. The side walls lie generally in a plane and have a greater front to back thickness than side to side thickness. Stiffening flanges with enlarged outer walls parallel to the frame are provided on the side walls for stiffening the frame in its plane to prevent unwanted bending and flecture of the frame. Holes in the flange reduce overall weight of the device while retaining the strengthening feature.

## Claims

### Claim 1

A lacrosse stick head frame comprising:
elongated side walls extending outwarding from each other at a throat portion ot a transverse top wall,
said side walls lying generally in a plane and formed of a resilient organic plastic material, having a predetermined stiffness,
means extending from said throat portion towards said transverse top wall for stiffening said side walls in said plane,
said means comprising a flange extending outwardly from the side walls and having holes therein for obtaining desired stiffness in said frame at a desired weight,
said flange having an outer enlarged wall enlarged in a direction substantially perpendicular to said flange providing stiffness to said side walls.

### Claim 2

A method of providing side to side increased rigidity in a lacrosse stick head frame comprising:
providing said frame with a substantially planar flange extending substantially outwardly from said side wall in the plane of said frame or parallel thereto and having an end wall at an outer portion thereof enlarged in a direction substantially perpendicular to said plane of said frame to define an I-beam construction with said side wall, said flange having cut-out portiosn to crease overall weight of said frame.

### Claim 3 (depends on 2)

A method in accordance with claim 2 wherein said lacross stick head frame is formed by injection molding.

### Claim 4

In a lacrosse stick head frame having elongated sidewalls extending upwardly from each other at a throat portion to a transverse top wall, with the sidewalls lying generally in a plane and formed of a resiliently organic plastic material having a predetermined stiffness, the improvement comprising, means extending from the throat portion toward the transverse top wall along the outside of each sidewall for stiffening said sidewalls in said plane with said means comprising an outwardly extending flange having holes therein for obtaining desired stiffness in said frame at a desired frame weight,
said flange extending at least 25% of the distance along each sidewall from said throat to said top wall, and
an outer wall to said flange and enlarged in a direction substantially perpendicular to said plane in which said sidewalls are lying, wherein each of said sidewall portions act as an I-beam to provide increased rigidity against bending in said plane.
