Grip for sports equipment
The present invention relates to shafts, handles and hand grips of sports equipment that include concave embedded indentations, such as grooves, dimples or ribs, located along the shaft at a location of frequent hand placement. The finger grooves are specially located and structured to provide the shaft with grips that correspond to the way in which a player grips the shaft to enhance a player's control of the shaft when performing various skills, such as cradling, throwing, shooting, and scooping. The present invention is primarily designed for a lacrosse stick shaft, but is also equally applicable to other sports shafts, such as an ice hockey stick or field hockey stick. The invention may enhance control of the equipment for all level of players and may assist in training novices in hand placement along the shaft for performing various skills.
The present invention relates generally to shafts, handles and hand grips for sports equipment that include concave embedded indentations, such as grooves, ribs or dimples (hereinafter collectively referred to as “indentations”), located along the shaft at a location of frequent hand placement. The indentations are specially located and structured to provide the shaft with grips that correspond to the way in which a player grasps the shaft to enhance a player's control of the shaft when performing various skills. The present invention is primarily designed for a lacrosse stick shaft, but is also equally applicable to other sports shafts, such as an ice hockey stick or field hockey stick.
Lacrosse is an ancient game that originated with the Native Americans in North America, particularly in the northeastern United States and Canada. Traditionally, lacrosse sticks were made of wood, usually hickory or ash, and were one integrated piece of equipment so the shaft was not a separate and replaceable part. These sticks were handcrafted and varied in quality in terms of strength, weight, feel and balance in the player's hands. These wooden handles were susceptible to breakage, were heavy and had inconsistent quality, which proved disadvantageous from both a playability and safety standpoint. Also, because the shafts and the lacrosse stick head were one integrated piece of equipment, if the shaft broke the entire stick had to be replaced.
In 1967, the molded plastic lacrosse stick head, as described in U.S. Pat. No. 3,507,495, was developed, which greatly revolutionized the sport of lacrosse. The invention allowed lacrosse sticks to be mass produced, as well as manufactured with consistency in terms of quality and consistency in shape. Wood shafts continued to be used, although they were still susceptible to breakage and were heavy.
In the 1970s, shafts of metallic construction, as described in U.S. Pat. No. 4,037,841, were developed. These metal shafts, in large measure, replaced the wood lacrosse stick handles, particularly in the men's game. The advantage of such construction was that the metal shafts could be mass produced with uniform quality, strength and weight, and were generally stronger than wood shafts.
Today, lacrosse stick shafts are made from a variety of materials such as aluminum, chrome, aluminum alloy, titanium, Kevlar, scandium, magnesium, and other composite materials, such as graphite loaded plastics, which are described in U.S. Pat. No. 4,739,994, and are lighter and in some cases, stronger, than wood or the first metal shafts.
Historically, most improvements to lacrosse stick shafts were directed to the use of new and different materials with minor additional modifications such as knurling or the like as described in U.S. Pat. No. 4,206,918. All handles were very basic in their shape, generally octagonal, elliptical, oval, cylindrical, round or hexagonal or a combination thereof in cross-section and all were straight from end to end. Although the straight handles have proved highly satisfactory, a need exists for a handle or shaft that has structural and tactile features which improve stick handling and enhance a player's control of the shaft while performing various skills.
In lacrosse, hockey or other stick sports, players move and change their hand placement along the shaft to perform different skills. In lacrosse in particular, various combinations of hand placement are a critical part of the game, as it is essential for effective stick handling when cradling, scooping, throwing, or shooting the ball. In addition, when shooting or passing the ball, the player needs to have a firm grip on the shaft in order to maximize the force and torque, which produces a faster shot or pass.
Without a firm grip, a player can often lose control of the shaft and the shaft can slip in a player's grasp. This is particularly true given playing and weather conditions such as fatigue, perspiration, cold and hot temperatures, and/or wet weather. In addition, lacrosse and ice hockey require the players to use gloves that protect the hands but which reduce the player's feel and grip on the shaft.
Typically, manufacturers design handles for sports shafts that require variable hand placement without a grip as it makes the manufacturing process easier. To improve grip, players often use athletic or gauze tape on their shafts in locations that coincide with their hand placement in order to improve stick control, produce faster shots, serve as a tactile cue for hand placement when stick handling, and accommodate their individual playing style and preference.
Although these tape alterations may improve grip, it is difficult to build shapes out of the tape that complement finger shape and placement. Furthermore, the tape rarely adheres well to the shaft and tends to peel and wear off over time. Thus, players must constantly remove and replace the tape. Also, if the lacrosse shaft breaks, then the player must re-tape and re-customize his or her new shaft to try to replicate the grip design from the broken shaft.
Other efforts to provide improved grip and control of sticks or handles are separate sports grips applied over a straight shaft. U.S. Pat. No. 6,500,079 to Tucker, Sr., for example, teaches a variable hand placement sports equipment shaft or handle, such as a lacrosse stick, that includes a shaft and at least one overlay attached to the shaft at a location of frequent hand placement that contains ribs, grooves, hourglass and conical shapes. The overlays are preferably made of a material that is soft, pliable, deformable and tacky so as to provide the player with a better grip on the handle. Similar overlays are disclosed in U.S. Pat. No. 4,890,355 to Schulten, U.S. Pat. No. 5,482,270 to Smith, and U.S. Pat. No. 5,867,868 to Ward.
Furthermore, modifications to shafts for improved handling are available in the prior art. For example, U.S. Patent Application Publications 2005/0130759 and 2005/0130773, both to Hayden et al., teach lacrosse sticks with a improved grip and feel due to expanded portions and contoured locations for users' hand(s). An inward tapered portion and expanded portion allegedly assist a player in controlling the shaft, cradling a ball, passing and shooting.
U.S. Pat. No. 2,031,161 to Hamel discloses bulbous portions adapted to more comfortably fit the shape of the human hand and grooves to provide inter-engaging portions into which a hand becomes partially molded. U.S. Design Patent D475,425 S shows a cricket bat with a contoured handle, which may accommodate finger gripping. Other types of contoured shafts are disclosed in U.S. Pat. No. 4,351,528 to Duplin, U.S. Pat. No. 6,752,730 to Brine, Jr. et al., and U.S. Pat. No. 4,206,918 to Lewis, Jr.
Although contoured sports shafts are generally known for accommodating the human hand, the prior art fails to disclose an integrated contoured grip with indentations, embedded grooves, ribs or dimples in the shaft that may be sized to accept human fingers in order to assist in the controlling of the shaft.
It is therefore an objective of the present invention to provide a grip with embedded indentations in the side of a sports shaft or handle, such as for a lacrosse stick or hockey stick that provides improved handling and control. It is further an objective of the present invention to provide more safe sports equipment that does not slip out from the player's grasp.
The following disclosure describes a novel sports equipment shaft that overcomes the deficiencies of the prior art.
BRIEF SUMMARY OF THE INVENTIONThe following disclosure and claims relate to a stick, pole, shaft, or handle for use in recreational and/or competitive sports. For example, the invention may find application in the areas of lacrosse, ice hockey, and field hockey sticks. More particularly, the present invention relates to a variable hand placement sports equipment shaft or handle that has generally concave, semi-round, indentations, which may be dimples, finger grooves, or ribs, embedded, or pressed into the structure of a sports equipment handle, stick, pole or shaft along the longitudinal plane. The indentations may be sized to accept human fingers and can maximize the resultant force of the fingers grasping the shaft, thereby enhancing the power, stability, firmness, accuracy, and efficiency of the gripping action of the fingers and hand using the shaft. The indentations increase grip friction between the player's hand or glove and the shaft, improve the player's hold on the shaft, and resist the twisting of the shaft. The indentations also may assist in training novices in hand placement and may enhance control of the equipment for all level of players.
The indentations may be placed in locations of frequent hand placement to accommodate the way in which a player moves his hands along the shaft to enhance a player's control of the shaft when performing various skills. Players in any “stick” sports with variable hand placements, such as lacrosse, hockey, and the like can benefit from the invention's strategically located indentations. For example, optimally locating the indentations on a lacrosse stick can improve a player's scooping, cradling, throwing and shooting skills.
According to the present invention, a sports equipment handle, such as a lacrosse stick, may be provided with one or more indentations located along the shaft. According to one embodiment, the indentations may be located along the entire “front” side of the shaft. According to another embodiment, the indentations may be located along the entire “back” side of the shaft. According to yet another embodiment, the indentations may be located on both the front and the back sides of the shaft. According to another embodiment, the indentations may be located in a combination of front and back sides of the shaft to mimic hand placement while performing various skills.
The present invention also applies to any cross-sectional shape of the shaft. For example, if applying the invention in a lacrosse stick, the cross-section may be octagonal, elliptical, oval, tear drop, cylindrical, round, hexagonal or a combination thereof, solid or hollow, and applies equally to men's and women's lacrosse sticks, sticks for players of all sizes and ages, sticks used in competitive or recreational lacrosse, and any size sticks.
The present invention is adaptable to provide unique advantages for different types of players. For example, for experienced players, the present invention can provide improved grip and feel, and can improve stick handling, passing and shooting accuracy, and shot speed. For youth players, the present invention can provide an educational tool for teaching proper hand placement for performing various lacrosse skills, such as scooping, throwing, catching and shooting.
While hand placement along the shaft follows certain general practices, players handle the shafts differently; for example, a player may “choke up” more on the shaft and keep his or her hands closer together. Also, there are different lengths of shafts that are permitted for lacrosse. Under the NCAA men's lacrosse rules, offensive players are permitted to have shorter shafts (with a 40-42″ overall stick length including the stick head) and defensive players may have longer shafts (52″-72″ including the stick head). It is also common for children or box lacrosse players to cut their shafts even further, to either accommodate small hands and bodies of children or to improve stick handling for box lacrosse. The invention can accommodate shafts of different lengths and sizes because the indentations can be provided along the entire length of the shaft to allow for maximum hand placement locations and accommodate the manner in which a player grabs the shaft.
BRIEF DESCRIPTION OF THE DRAWINGSNovel features and advantages of the present invention in addition to those noted above will become apparent to persons of ordinary skill in the art from a reading of the following detailed description in conjunction with the accompanying drawings wherein similar reference characters refer to similar parts and in which:
The invention will now be described with reference to
The present invention applies equally to any type of shaft material—whether wood, aluminum, chrome, aluminum alloy, titanium, Kevlar, scandium, magnesium, and carbon graphite, plastic and other composite materials, or spiral wound laminated wood (“wound wood”) as described in U.S. patent application Ser. No. 10/867,541 to Botten et al., which is herein incorporated by reference.
The shaft 12 may be provided with indentations 16, which may be contoured to mimic the shape of a finger on the shaft and shaped to conform to a player's hand to improve grip and torque on the shaft. As will be described in greater detail below, the indentations may have any suitable shape, orientation, and depth to accommodate a player's bare or gloved fingers. For example, the indentations may be generally round, oval, rectangular, or square. The indentations may provide enough of a grip for a player to control the stick handle with one hand while dodging opposing players; yet the indentations are not tacky, thus allowing a player's hands to shift and slide into various positions. The indentations 16 may be formed in a variety of ways. For example, if shaft 12 is wooden, the indentations may be filed, burned, or cut into the wood, or if the shaft is made of “wound wood” as referenced herein, it may be pressed or molded in the wood or may be provided in any other suitable manner. In the event the stick is metal or other composite material, the indentations may be formed by melting, molding, casting, bending, deforming, or shaping the shaft in any other suitable manner.
As shown in
The shaft may have any number of indentations on the front, back and/or sides of the shaft. Indentations 16 may train and encourage optimal hand placement for various skills. Sufficiently skilled players may find that indentation placement and design enhances grip, comfort and/or performance.
According to a first embodiment of the invention, the front side of lacrosse shaft 12 is provided with indentations 16. The indentations may be provided in any portion of the shaft 12 or may be provided along the entire length, as shown, for example, in
According to a second embodiment of the invention, shown in
According to a third embodiment, shown in
According to a fourth embodiment, shown in
Although the front of the shaft 12 may have any number of indentations 16, according to the fourth embodiment, shown in
Grips 28 and 32 teach and foster proper cradling, underhand throwing, and sidearm throwing. Placing grips 28 and 32 opposite grips 20 and 22 allows the player to quickly shift from one grip position to the other. As the player develops, the grips continue to enhance stick handling performance and comfort.
The embodiments described above correspond to a 30-32 inch shaft as is a standard length for an offensive stick in men's lacrosse. The invention may also be used for a defense stick, which is longer in length than the offensive stick, for a goalie stick, or for a youth, box-lacrosse, recreational stick, women's lacrosse stick or other stick with a custom length. The peaks or indentations may be any shape, size or length to accommodate the proper, optimal, and/or comfortable positioning of the player's hands and fingers.
