Description
- This application is a divisional application of, and claims priority to, U.S. Ser. No. 12/958,956 filed Dec. 2, 2010 which is incorporated herein by reference.
- Not applicable.
- 1. Field of the Invention
- The present invention relates generally to a game ball, and in particular, to a game ball having a grip enhancing material affixed to its cover.
- 2. Description of Related Art
- The covers of conventional baseballs and softballs are typically formed from two panels which are positioned over an interior structure of the ball and stitched together to form a seam. The panels may be formed from a variety of materials depending on the anticipated use and desired cost of the ball. For example, the panels may be formed from leather, polyurethane, polyvinylchloride, or blends thereof. Alternatively, baseballs and softballs may be “stitchless” having an outer cover that is molded from a polymeric material. These stitchless balls may have simulated stitching molded to the outer cover in the same general location as the stitches on a conventional baseball or softball. Before throwing either type of ball, a player typically utilizes the seams to obtain a preferred grip on the ball. Further, players and coaches view the seams of a thrown ball in order to determine the ball's rotation, which typically is indicative of the flight path that the ball will follow.
- The present invention is directed to a game ball having grip enhancing material on the exterior surface of the ball, wherein the grip enhancing material is presented on the ball in a pattern that resembles or mimics the pattern of the seam on a conventional stitched ball. The grip enhancing material is preferably presented in a prominent color to enable players and/or coaches to determine the rotation of the ball when thrown.
- One embodiment of the present invention is directed toward a game ball comprising a cover having at least two panels that are coupled together along a seam. Each panel comprises an outer surface that is formed of a first material. A second material that is easier to grip than the first material is affixed to each of the panels adjacent to the seam. The second material may be affixed to the first material in any manner. For example, the second material may be sprayed, coated, screened, adhered, welded, bonded, or chemically bonded to the first material. The second material enhances a player's ability to grip the game ball by presenting a surface surrounding the ball's seam that is easier to grip than the remainder of the ball's cover. Preferably, the second material also has a different color than the first material in order to enhance a player's ability to determine the rotation of the ball when thrown. Most preferably, stitching joins the two panels and the second material is the same color as the stitching.
- The second material of the game ball is easier to grip than the first material. For example, the second material may comprise a material that is tackier than the first material; a material that has a higher coefficient of friction, static and/or dynamic, than the first material; a material that has a lower hardness or durometer than the first material; and/or a material that is textured differently from the first material. Preferably, the second material of the game ball has a greater frictional interaction with a player's hands than the first material.
- Another embodiment of the present invention is directed toward a baseball or softball comprising a cover having an outer surface that is formed of a first material. A second material that is easier to grip than the first material is affixed to the cover in the same location as the seam on a conventional baseball or softball. Preferably, the ball's outer surface is molded and stitchless, meaning that the outer covering is not made by stitching panels together. While the ball may be stitchless, it may have simulated, molded stitches. Preferably, the second material, when positioned on a planar surface, comprises a continuous strip having two generally semicircular ends each integral with a pair of opposed concave sides (e.g. a
FIG. 8 configuration). The second material is easier to grip than the first material as described above. - Additional aspects of the invention, together with the advantages and novel features appurtenant thereto, will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned from the practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.

Preferably, the static coefficient of friction for the second material is between 1 to 1.4, and most preferably between 1.1 to 1.3. Preferably, the dynamic coefficient of friction for the first material is between 0.5 to 0.95, and most preferably between 0.75 to 0.95. Preferably, the dynamic coefficient of friction for the second material is between 0.95 to 1.2, and most preferably between 1 to 1.1. - The
second material 22 may present a textured surface that enhances a player's ability to grip thegame ball 10. For example, thesecond material 22 may have a pebbled surface or have any other pattern of contours, protrusions or depressions that present a textured surface. If thesecond material 22 has protrusions, preferably the protrusions have a height that is less than the height of thestitching 18 on the ball, which is preferably between approximately 0.01 to 0.08 inches. - The
second material 22 may also be easier to grip than the first material because the second material is tackier than the first material. For example, thesecond material 22 may be formed from an adhesive or any of the other materials referenced above that is tackier than the first material. - It is also within the scope of the invention for the
second material 22 to have a lower hardness or durometer than the first material so that thesecond material 22 is easier to grip than the first material. - The
second material 22 also preferably has a different color than the first material so that it is easier to determine the ball's rotation when it is thrown or pitched. Typically, players and coaches focus on the seams of a thrown ball in order to determine the ball's rotation, which can be indicative of the flight path that the ball will follow. Because thesecond material 22 is visually more prominent than the seams on a typical baseball or softball, it is easier for players and coaches to determine the rotation ofball 10 than the rotation of a typical softball or baseball. Theball 10 may be used for training pitchers and batters to spot the rotation of different types of pitches since it is easier to view the rotation ofball 10. For instance, pitchers and pitching coaches can more easily see the rotation ofball 10 when it is pitched to determine and improve upon a pitcher's effectiveness.Ball 10 may also be used for training a batter to spot different types of pitches based on their rotation, which can help the batter anticipate a ball's flight path. Thethread 18 that joinspanels second material 22. However, it is within the scope of the invention for thethread 18 to be a different color than thesecond material 22. Preferably, thesecond material 22 has a color that is highly visible and that contrasts with the color of the first material to enhance visibility. Most preferably, thesecond material 22 is formed from a bright red or neon color that contrasts with the remainder of theball 10. If theball 10 is for use in a competition that is sanctioned by a particular organization, preferably the second material is the color that is required by that particular organization. For example, thesecond material 22 is preferably blue if theball 10 is a softball for use in an USSSA sanctioned competition, thesecond material 22 is preferably black if theball 10 is a softball for use in a NSA sanctioned competition, and thesecond material 22 is preferably green if theball 10 is a softball for use in an ISA sanctioned competition. -
Ball 10 is particularly advantageous for use as a training aid because thesecond material 22 makes it easier for a player to grip the ball and because thesecond material 22, when having a different color than the first material, makes it easier for a player or coach to determine the ball's rotation when thrown. However, it is also within the scope of the invention forball 10 to be used as a competition baseball or softball if desired. - The shape of
