Abstract

A handle is adapted to be held by a player and a striking end is adapted to contact and propel an object. A structure for a hockey stick is described by using a single, hollow tube of composite material, wherein tubular “ports” extend through the hollow tube. The ends of the ports are bonded to the walls of the hollow tube. The ports improve the stiffness, strength, aerodynamics and comfort of the hockey stick.

Claims

1. A sports stick of the type having a relatively long handle shaft characteristic of a hockey or lacrosse stick and a striking end secured to said handle shaft which is adapted to control and propel a ball or puck, the striking end being designed for the intended sport;

wherein said handle shaft is formed primarily of a single, hollow primary tube having an interior, said handle shaft being adapted to be held by a player;

wherein said handle shaft is fabricated of a relatively rigid material with limited flexibility;

wherein said tube has at least one pair of aligned holes extending through opposite wall portions of said tube; and

wherein said handle shaft further includes a hollow port tube associated with each said pair of holes, each port tube having opposite ends disposed in said pair of holes and extending across the interior of said primary tube, and wherein said opposite ends are bonded to said opposite wall portions within said holes to form a port extending across said interior.

2. The stick as set forth in claim 1, wherein the primary tube and each port tube are made of composite material.

3. The stick as set forth in claim 2, wherein the stick is a hockey stick.

4. The stick as set forth in claim 2, wherein said handle shaft and said striking end are one piece.

5. The stick as set forth in claim 2, wherein the handle and striking end are separate pieces.

6. The stick as set forth in claim 2, wherein said handle shaft includes a plurality of pairs of aligned holes and a corresponding number of port tubes.

7. The stick as set forth in claim 2, wherein said handle shaft has a longitudinal axis, and wherein said at least one port is at least generally oval in shape, to form a pair of arches, with the long dimension of the oval axially oriented.

8. The stick as set forth in claim 6, wherein said handle shaft has a longitudinal axis, and wherein said ports are at least generally oval in shape, to form a pair of arches, with the long dimension of the oval axially oriented.

9. The stick set forth in claim 1, wherein the port tube is made of metal.

10. The stick set forth in claim 1, wherein the primary tube is made of metal and the port tube is made of a composite material.

11. The stick set forth in claim 1, wherein the primary tube is made of a composite material and the port tube is made of metal.

12. The stick set forth in claim 1, wherein said stick is a field hockey stick.

13. The stick set forth in claim 1, wherein said stick is a lacrosse stick.

14. The stick set forth in claim 1, wherein said handle shaft is formed by heat molding a composite material having unidirectional fibers, and wherein said holes and port tube are formed by providing a pre-preg tube about a mold member, and positioning the pre-preg tube and mold member, prior to molding, between fibers on said opposite wall portions, so that, during molding, said holes are formed without breaking or cutting of fibers.

15. A composite hockey stick for producing geometric shapes and improving the flexibility and strength and other playing characteristics of the hockey stick comprising, in combination:

a stick handle fabricated of a handle tube of multiple plies of carbon filaments held together with an epoxy binder, the filaments of each ply being parallel to one another, the stick handle having a long generally hollow rectangular configuration having a top end, a bottom end, a front face, a rear face, and a pair side faces;

at least one pair of aligned holes extending through the front and rear faces; and

a hollow port tube extending through each said pair, wherein said port tube has a peripheral wall and opposite ends, and wherein said opposite ends are disposed in said holes and bonded to said handle tube.

16. The hockey stick as recited in claim 15, wherein said handle includes a plurality of pairs of aligned holes extending through the front and rear faces and a corresponding number of port tubes.
