Description

ARTICLE OF MANUFACTURE AND METHOD FOR

IMPROVING HANDLING AND PERFORMANCE OF SPORTS EQUIPMENT

AND FOR ADVERTISING THEREON

This application claims the benefit of U.S. Provisional Application Serial

No. 60/289,699 filed May 9, 2001 entitled METHOD, SYSTEM AND ARTICLE OF

MANUFACTURE FOR TAPING A STICK, IMPROVING PLAYER PERFORMANCE,

AND ADVERTISING.

Field of the Invention

The present invention relates to an article of manufacture and method for using

the article in connection with a ball or puck which results in improved handling and

performance and enabling advertising thereon.

Background of the Invention

Sporting equipment for use with a ball or puck is often modified by players at

the point of contact with a ball or puck, or at the point of contact with the player, so as to

modify, and preferably improve, handling and performance of the equipment with a ball or

puck, or to improve the durability of the sporting equipment. For example, in the game of ice

and/or in-line hockey, hockey sticks may be made of wood, glass fibers, graphite, and/or

similar materials, such as engineering plastics. Hockey sticks are frequently taped by hockey

players at the point of contact with a puck so as to improve handling and performance of tlie

stick in relation to the puck or ball. Tape conventionally used is black friction tape or

electrical tape, write adhesive tape, or clear plastic tape. Tape typically does not allow for

desired adjustments to speed, control, accuracy, damping, resilience or lift or trajectory, i.e.,

handling and performance, of the puck or ball. In addition, tape may get easily cut by stick,

puck or skate blade, absorb water or otherwise rapidly lose damping capability or resiliency. Occasionally, players adhere plastic cutouts to the stick to attempt to improve

handling and performance. Adhesive cutouts present disadvantages similar to tape as

discussed above. In addition, cutouts and tape adhere to the stick which makes removing the

cutout or tape difficult. Another disadvantage of conventional tapes and cutouts is that they

do not readily enable advertising. Conventional tapes and cutouts also typically do not allow

for wear-resistant configurations in desired locations on the stick. For example, at edges of a

hockey stick which tend to contact the ice, conventional tapes and cutouts are either not wear-

resistance enough or tend to interfere with stick or player performance, or may not be in

compliance with league rules.

In addition to tape and cutouts, shrinkable materials have been tried but are not

widely used. Disadvantages of these materials include those listed above for tape and

cutouts, but also include that these materials have not typically provided the desired

improvement in handling and performance, that devices are required to shrink the material to

the stick, and that heating the stick with the shrinkable materials tends to weaken, damage or

deform the stick.

What is desired therefore is an article of manufacture and a method for use in

connection with sporting equipment for improving handling and performance of the sporting

equipment in relation to a ball or puck. What is further desired is an article of manufacture

and a method for improving handling and performance of the sporting equipment which

readily allows for advertising. What is further desired is an article of manufacture and

method for providing localized improvement in wear-resistance without interfering with stick

or player performance, and which complies with league rules. Summary of the Invention

Accordingly, an object of the invention is to provide an article of manufacture

and method for improving performance of a hockey stick, such as when a player is handling,

passing and shooting the puck or ball. Another object of the invention is to provide an article

of manufacture and method for improving performance of a hockey stick that enables

advertising to be displayed thereon. Yet another object of the invention is to provide an

article of manufacture and method for increasing player safety.

These and other objects, features and advantages of the invention will become

apparent from the following detailed description taken in conjunction with the accompanying

drawings showing an illustrative embodiment of the invention. More particularly an article

of manufacture is provided having a surface configuration and/or composition resulting in

improved handling and performance, such as improved puck speed, control, accuracy, or lift.

In addition, an article of manufacture is provided which provides the improved handling and

performance and allows for advertising.

Detailed Description of the Invention

Figs. 1 A through IC depicts an article of manufacture 10 (or sleeve) in

accordance with one embodiment of the invention. In this embodiment, article 10 has a tape¬

like pattern 12. Fig. 2 shows article 10 on a hockey stick 1 positioned such that article 10

will be contacted by a hockey puck during a hockey game. It is understood that the term

"hockey stick" encompasses both ice hockey sticks and street hockey sticks. It is understood

that article 10 may be used in connection with other sports equipment (not shown), such as a

baseball bat, ping-pong racket. Figs. 3 A through 3C and Fig. 4 show article 20, another

embodiment of the invention, having a grooved pattern 22. Figs. 5 A through 5C and Fig. 6

depict article 30, yet another embodiment of the invention, having a nibbed pattern 32. It is

understood that nibs 32 may have a face that is slightly rounded and convex, as shown, or

may have flat planar faces. Figs. 7A through 7C and 8, illustrate another embodiment of the

invention, article 40, which has a dimple pattern 42. As with the nib pattern 32, dimples 42

may have a concave shape, as shown, or may have another non-uniform shape so long as the

nib 42 is in the shape of an indentation of some kind. It is understood that nibs 32 and

dimples 42 need not have a generally circular shape but may have a shape, such as an

irregular shape, triangular shape or rectangular shape or any combination thereof. Figs. 9A

through 9C and 10 depict another embodiment of the invention, article 50, which has angled

grooves 52. Grooves 52 may be angled in any direction, including in a direction opposite to

that shown in Fig. 10, which shows grooves running from the top of the face of the stock to the bottom of the face of the stick, with each groove having its bottom end closer to the

handle of the stick than is the top of the groove. Grooves 52 may also be in one direction on

one side, and in another direction on the other side of stick 1. Grooves 52 may also be

aligned relative to the face of the stick 1 or the handle of the stick 1 and the likely direction of

contact with a puck in play such that speed or direction of the puck departing from the stick 1

may be influenced in a predetermined manner. More specifically, these grooves may impart a

greater rate of rotation, or spin, to the puck.

Patterns 12, 22, 32, 42 and 52 are examples of the types of patterns that may

be used in accordance with the invention. It is understood that a variety of patterns may be

used which result in the desired handling and performance. For example, angled groves, such

as angled grooves 52, may be used to influence the direction of a shot. In addition, a

combination of patterns may be used. For example, as shown in Fig. 17 A, angled grooves

129 may be provided on one side of article 120 and dimples 124 may be provided on the

other side of article 120. Nib 32 or an abrasive pattern is useful in increasing control over the

puck. An article having a pattern effective in increasing puck speed, such as one utilizing

hard materials or very elastomeric or resilient materials, is useful for defensive hockey

players as well as those who shoot or pass. An article having a pattern or comprised of

resilient material is useful for hockey goal tenders to deaden a puck blocked by the stick

against the stick.

Preferably, the article or sleeve is comprised of material which exhibits high

flexibility at room temperature and less flexibility at temperatures of around 0 and 10 degrees

Celsius. In this manner, the article or sleeve can be easily placed over the blade of the hockey

stick from either blade end or handle end at room temperature due to its greater elastomeric qualities, and during game play on ice the article is less likely to slip off the blade due to the

decrease in elastomeric properties.

Article or sleeve 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110 and 120 may also

advantageous be comprised of a unitary material having a harder, more wear-resistant

material at the bottom edge of the article or sleeve 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110

and 120 to increase the useful life, and a more elastomeric material in the portion of the

article or sleeve 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110 and 120 expected to come in

contact with the puck. Article may have a wedge-shape, such that the bottom of the article is

thicker than the top of the article. This may advantageously be used to increase the lift on the

puck.

Figs. 11 A through 17D depict articles or sleeves 60, 70, 80, 90, 100, 110, and

120 further comprising advertising 64, 74, 82, 94, 104, 114, 129 as well as patterns 62, 72,

82, 92, 102, 112, 126, and 128. It is understood that advertising may a pattern on the article.

Advertising 64, 74, 82, 94, 104, 114, and 129 may be in color, comprise logos or other banner

advertising.

Figs. 18 A through 18C show the article 50 being disposed over the stick 1.

Preferably, article 50 is disposed over the handle of the stick 1, however, article 50 may be

disposed over the blade of the stick 1. Article 50 as shown for example in Figs. 18 A through

18C is positioned and/or sized such that it is in the area of the blade that comes in contact

with the puck. It is understood that article in accordance with the invention may be

positioned over the tip of the blade of the stick to improve safety.

The sleeve that is the subject invention can improve the ice or street (in-line

skate) hockey player's performance in handling, dribbling, passing and shooting the puck.

Various surface configurations applied to the sleeve that is the subject invention will improve puck speed, control, accuracy and lift. Various non-limiting examples of surface

configurations are shown in the Figures. In a non-limiting embodiment of the instant

invention, a surface configuration comprising a plurality of diagonally configured ridges

functions to increase the spin and centrifugal force the puck, thus enhancing the player's

accuracy and control of the puck. Likewise, the material from which the sleeve is constructed

will also affect the speed of the puck or ball. For example, the sleeve is constructed from a

resin with a high coefficient of elasticity will impart more speed to a struck puck than a

sleeve that is the subject invention constructed from a material with a comparatively low

coefficient of elasticity. In one embodiment of the invention, the sleeve is designed for a

goalkeeper who desires to reduce the energy of rebounds from the blade of the hockey stick.

Accordingly, the configuration and/or material of the sleeve (for example, a material with a

low coefficient of elasticity) are designed to absorb impact by the puck or ball and dampen or

decrease the energy of a puck or ball rebound.

In another non-limiting embodiment, the sleeve has varying thickness and

configurations on the top and bottom of the blade as well as on the forehand and backhand

side of the blade. In another embodiment, the sleeve that is the subject invention can be sold

on a roll and the players can cut whatever length is desired to optimize the stick to suit

various nuances of their individual skills, or specific demands associated with their position.

The sleeve's surface configurations simulate the patterns and configurations

produced by regular tape and taping techniques that are allowed by the professional and

amateur leagues, but have the aforementioned benefits of the sleeve. Benefits of the sleeve

include but are not limited to: (1) an information display area for advertising, team logos, or

team colors; (2) easy installation and deinstallation that will not damage or alter the shape of

the stick; (3) increased durability of the hockey stick blade; and (4) affecting the control, handling and speed of puck or ball. In another embodiment, the bottom edge of the sleeve is

made thicker or of heavier material to prevent wear. Additionally, the present invention

provides advertisers the ability to advertise in a new manner.

The sleeve can be manufactured by methods including but not limited to

extrusion technique, high performance blow mold technology, or dip molding which allow

for printing of indicia, such as logos, advertisements, brand names, and other information.

The sleeve can be packed, for example, in a roll making the printing easier. Corporate logos,

for example, can be printed^' and prominently displayed on the sleeve that is the subject

invention. The sleeve can also be produced in a multitude of colors/logos corresponding to

the colors and/or logos of various NHL/AHL/IHL and college and national teams, as well as

high school and youth hockey programs.

In one embodiment, the sleeve is constructed from recyclable materials and it

is reusable and not permanently attached to the stick in anyway. The player will have choices

as to puck handling and shooting performance based on the surface configurations of the

sleeve. One of the major advantages of the sleeve is that it allows a player to choose from an

array of materials and surface configurations so that their stick can be customized to

optimally match his or her position, individual skill level and style of play. Because it is

stronger and more resistant to cuts from other blades and skates, the sleeve also increases the

useful life of the hockey stick, as well as increasing player safety, by reducing the amount of

dangerous debris on the ice from damaged or worn sticks. In one embodiment, the sleeve is

elastic and is attached by sliding it on from the top of the stick. In another embodiment, the

sleeve is attached by sliding it on from the end of the blade. The sleeve can have team colors such as blue and red for youth ice hockey

schools. In another embodiment it covers the tip of the blade and making it safer for the

players.

The sleeve does not use a heat source to shrink-fϊt it onto the blade of the stick,

thus making is easy to install and remove from the stick. Additionally, by not requiring heat

to install the sleeve that is the subject invention onto the stick, the stick and the sleeve is not

subjected to heat damage and deformity. The sleeve and the stick remain uniform and not

weakened. There is no need for propane torches, even children can use the product. The

sleeve is reusable, thus extending its life. If the shaft of the stick breaks ~ the most common

type of break in hockey sticks — the sleeve can be re-used.

While the disclosed embodiments apply the present invention to an ice or in¬

line skate hockey stick, it will be appreciated by those of skill in the relevant art that the

instant invention can be readily applied to other athletic equipment including but not limited

to: baseball/softball bats, golf-clubs, tennis racquets, ping-pong paddles and croquet mallets.

In another non-limiting example, an "industrial polymer" based material is

used for construction of the sleeve. Polymers are chemical, compounds whose molecules are

very large, often resembling long chains made up of a seemingly endless series of

interconnected links. The size of the molecules, together with their physical state and the

structures that they adopt, are the principal causes of the unique properties associated with

plastics — including the sleeve's ability to be molded and shaped.

In a non-limiting example, the sleeve is made from a "thermoplastic resin."

The property of plasticity inherent to thermoplastic resins allows the sleeve to be capable of

being molded (into a great variety of sizes and patterns) and remolded repeatedly, as

previously mentioned. The plastic behavior of the sleeve is also influenced by its morphology. By

definition, thermoplastic-based materials retain their molded shapes up to a certain

temperature. Above T_g the amorphous parts of the polymer enter the rubbery state, in which

the molecules display increased mobility and the material becomes plastic and even elastic

(that is, able to be stretched).

The sleeve's rubbery material, for example, consists of elastomers having

strong intermolecular associations but no real chemical interlinks. If the associations between

the molecules are strong enough to prevent flow under moderate stresses, such materials can

serve as practical rubbery solids. Also, because the weak interlinks give way at high

temperatures, allowing the material to take on a new shape in response to pressure, they can

be reprocessed and reused. For this reason the sleeve may be a "thermoplastic elastomer".

Based on the sleeve's features/characteristics, in the non-limiting example, the

material used in the production and industrialization of the sleeve is classified as a "Low

Durometer Thermoplastic Elastomer", like a Low Density Polyethylene (LDPE), as an

example.

The most common chemical product manufacturing processes have extrusion

as their basis. In the case of injection molding, the 'extruder' is part of the machine and is

also used to inject the plastic into the mold. Extrusion can be used to incorporate pigments

and additives for making a compound. However with modern equipment these additives are

often added at the machine during processing.

More specifically, to produce the sleeve that is the subject invention extrusion

of blow film can be employed. A ring die is used. The sleeve's material is directed upwards

as a tube. Air pressure is maintained in the tube to control the sausage like bubble, which is

nipped between the rollers to provide the seal. The film is then wound onto reels. The blow-molding machine is based on a standard extruder barrel and screw

assembly to plasticize the polymer. The molten polymer is led through a right angle and

through a die to emerge as a hollow (usually circular) pipe section called a parison.

When the parison has reached a sufficient length a hollow mold is closed

around it. The mold mates closely at its bottom edge thus forming a seal. The parison is cut

at the top by a knife prior to the mold being moved sideways to a second position where air is

blown into the parison to inflate it to the shape of the mold, thus creating the sleeve.

The foregoing merely illustrates the principles of the invention relative to a

particular embodiment. It will thus be appreciated that those skilled in the art will be able to

devise numerous other arrangements which embody the principles of the invention and are

thus within its spirit and scope. For example, while the disclosed embodiments describe the

present invention as being inserted over a hockey stick, those of ordinary skill in the art will

readily appreciate that the instant invention encompasses insertion of the article to other

sports equipment, including field hockey sticks, in-line hockey stick, bandy equipment,

baseball/softball bats, golf-clubs, tennis racquets, ping-pong paddles and croquet mallets.
