Hockey Stick Having Longitudinal Reinforcing Channels
A hockey stick having one or more channels defined in the upper and lower minor longitudinal surfaces of the stick handle. The channels improve the strength and durability of the stick without requiring complex molding or fabrication equipment.
The present application claims priority to U.S. Provisional Application Ser. No. 61/421761, filed on Dec. 10, 2010.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to sporting equipment and, more particularly, to a hockey stick having reinforcing channels extending longitudinally along a portion of the stick.
2. Description of the Related Art
A hockey stick is a piece of equipment used in field hockey, ice hockey or roller hockey to move the ball or puck. Sticks are approximately 1500-2000 millimeters long, composed of a long, slender shaft and a flat extension at one end called the blade. The curved part where the blade and the shaft meet is called a taper. The blade is the part of the stick used to contact the puck, and is typically 250 to 400 millimeters long.
Sticks have traditionally been made from wood, but in recent years, sticks made of more expensive materials such as aluminum, Aramid (kevlar), fiberglass, carbon fiber, and other composite materials have become common. In addition to weighing less, composite sticks can be manufactured with more consistent flexibility properties than their wooden counterparts. Composite sticks, despite their greater expense, are now commonplace at nearly all competitive levels of the sport, including youth ice hockey. Many professionals also use composite stick technology rather than the old wooden sticks. These new sticks are lighter, and provide a quicker release of the puck, resulting in a harder, better shot. However, composite sticks may be more susceptible to breaking and, due to the costs of materials and manufacturing, are costly to replace when they break.
Some conventional systems for improving the strength and durability of composite sticks involve combining composite materials and wood. Such systems are expensive to manufacture and thus produce costly sticks. Other designs involve the use of complicated stick shapes and cross-sections that require specialized tooling and manufacturing processes. Accordingly, there is a need in the art for a simple composite stick design that is easy and therefore less costly to manufacture while improving the strength and durability of the stick.
BRIEF SUMMARY OF THE INVENTIONIt is therefore a principal object and advantage of the present invention to provide a stick design that has improved strength and resistance to breakage.
In accordance with the foregoing objects and advantages, the present invention provides a stick design comprising at least one channel defined in a minor longitudinal surface of the stick. In a preferred embodiment, the present invention comprises a pair of opposing channels formed in both the upper and lower minor longitudinal surfaces of the stick. In yet another embodiment of the present invention, multiple channels are formed in the upper and lower minor longitudinal surfaces of the stick.
The present invention will be more fully understood and appreciated by reading the following Detailed Description in conjunction with the accompanying drawings, in which:

Stick 10 is preferably manufactured by bladder molding, but it should be recognized by those of skill in that art that other known processes may be used. The inclusion of channels 24 and 26 in a stick 10 manufactured in this manner has provided a measurable improvement in the strength of stick 10 and its resistance to impact, as measured by dropping a 20 lb weight from a height of 250 mm (increasing by 50 mm after five successful tests).
Claims
1. A hockey stick, comprising:
- a handle having first and second ends and a rectangular cross-section forming a pair of major surfaces and a pair of minor surfaces;
- at least one channel formed in at least one of said minor surfaces; and
- a blade interconnected to one of said first and second ends of said handle.
2. The hockey stick of claim 1, wherein said channel has a length that is about 60 percent of the handle length.
3. The hockey stick of claim 2, wherein said channel has a width that is about 25 percent of the handle.
4. The hockey stick of claim 3, wherein said channel has a depth that is about 15 percent of the handle.
5. The hockey stick of claim 1, further comprising at least a second channel formed one of said minor surfaces.
6. The hockey stick of claim 5, wherein said second channel is formed in the opposite minor surface from said first channel.
7. The hockey stick of claim 6, wherein each of said channels has a length that is about 60 percent of the handle.
8. The hockey stick of claim 7, wherein each of said channels has a width that is about 25 percent of the handle.
9. The hockey stick of claim 8, wherein each of said channels has a depth that is about 15 percent of the handle.
10. The hockey stick of claim 1, further comprising a plurality of channels formed in at least one of said minor surfaces.
11. The hockey stick of claim 10, further comprising a plurality of channels formed in the other of said minor surfaces.
12. The hockey stick of claim 11, wherein each of said channels has a length that is about 15 percent of the handle.
13. The hockey stick of claim 12, wherein each of said channels has a width that is about 25 percent of the handle.
14. The hockey stick of claim 13, wherein each of said channels has a depth that is about 15 percent of the handle.
