The present invention relates generally to a ball glove for baseball, softball and other sports. In particular, the present invention relates to a ball glove including ball spin reduction technology to facilitate a ballplayer's ability to catch, grasp and retrieve a ball during play.
Ball gloves for use in baseball, softball and other sports are well known. Ball gloves typically include a front panel connected to a corresponding back panel to form a hand cavity. The front and back panels typically generally resemble the shape of a human hand and when assembled form five stalls for receiving the thumb and fingers of a user's hand. The front and back panels form a hand opening at the lower edge of the glove. A webbing is typically connected between the thumb stall and the index finger stall of the ball glove. Ball gloves also typically include a hand opening for enabling a user to insert his or her hand into the hand cavity of the ball glove, and, often, an index finger hole for enabling the user's index finger to rest on the back portion of the index finger stall during use. Many existing ball gloves are formed of high quality, relatively expensive materials, such as natural leather, synthetic leather, and combinations thereof.
Ball gloves are generally constructed of highly durable materials to withstand the repeated impact of fielded balls during play and the scrapes and other contact with the playing field and other objects during play. Also, ball gloves are generally sized to be much larger than the hand of the ball player. The increased size is desirable in that it provides a larger pocket, or catching area for receiving a ball during play, enabling a player to reach more balls in play than would otherwise be possible with a glove matching the size of a player's hand. The size of a ball glove also typically varies by position. An outfielder's ball glove is typically larger than infielder's ball glove, and a first baseman's ball glove is typically larger than an outfielder's glove.
In many baseball game plays, the player's ability to catch the ball with a ball glove, grasp and retrieve the ball within the ball glove, and throw the ball is critical in determining whether the play will be considered a success or a failure (an out or a safe baserunner). Infielders desire to quickly field, retrieve and throw ground balls in order to throw out baserunners. Catchers desire to catch, retrieve and throw a pitched ball in order to throw out a baserunner attempting to steal a base. Outfielders desire to quickly field, retrieve and throw hit balls back to the infield in order to throw a baserunner out or to limit the progress of a baserunner about the base paths. A fraction of a second can be the difference between a baserunner being called out or safe. Pitched and hit baseballs and softballs typically include some amount of spin, including side spins, top spins and back spins. It is well-known that a high spinning baseball or softball can be more difficult to field for a player than a non-spinning or low spinning baseball or softball. A high spinning ball can be more difficult for a player to field, to retain in his or her ball glove, and to retrieve from his or her ball glove due to the rotation of the ball.
The present disclosure describes an example ball glove configured for catching a ball. The ball glove includes a front glove portion, a back glove portion and a webbing. The webbing has a front face that forms a pocket of the glove. The webbing provides the ball glove with a large catching surface for cradling a ball that is caught. The webbing also provides the ball glove with a surface for absorbing the initial impact of a ball being caught, reducing impacts directly to the player's hand within the glove. As a result, it is often desirable to catch a ball using the webbing 16 of the ball glove.
The webbing includes a spin reduction texture. The spin reduction texture includes a first pattern of raised projection and/or recesses. Because the spin reduction texture is specifically provided on the webbing, the spin reduction texture is able to reduce spin of a caught ball almost immediately following impact of the ball with the ball glove. Moreover, because the spin reduction texture is specifically provided on the webbing as compared to other portions of the ball glove, a larger percentage of caught balls undergo spin reduction and are more easily retrieved from the pocket of the ball glove.
The example ball gloves will become more fully understood from the following detailed description, taken in conjunction with the accompanying drawings described herein below, and wherein like reference numerals refer to like parts.
Referring to
The front and back portions 12 and 14 are contoured sheet-like structures, each generally resembling a hand. The front portion 12 is coupled to the back portion 14. The term “coupled” refers to the direct or indirect connection, joining or linking of one component, part or article to another. The use of the term “coupled” can be interpreted in a manner similar to its use with railroad cars. A train engine can be directly connected to a caboose, or one, two, ten or any number of train cars can be linked between the engine and the caboose of a train. In both of these examples whether directly connected or indirectly linked by one or more train cars, the train engine is coupled to the caboose.
The front and back portions 12 and 14 are connected together to define a hand opening 17 and a hand cavity 18, and to form first, second, third and fourth finger stalls 20, 22, 24, 26, and a thumb stall 28. Each finger and thumb stall 20-28 defines an elongate cavity for receiving the respective finger or thumb of the user. The front and back portions 12 and 14 are preferably stitched together. In one preferred embodiment, the front and back portions 12 and 14 are coupled together through the use of weltings 30. Alternatively, the front and back portions 12 and 14 can be connected through other means, such as, for example, lacings 32, bonding, molding or adhesives and combinations thereof.
In some implementations, a binding 33 can be used at one or more edges of the front and/or back portions 12 and 14. The binding 33 generally wraps around and covers the edges of the front and back portions. The binding 33 can be stitched to one or more pieces of the front and/or back portions 12 and 14. Alternatively, the binding 33 can be coupled to the front and back stall portions through adhesives, stapling or other conventional fastening means. The binding 33 is preferably formed of a generally flexible, durable material, such as leather. Alternatively, the binding 33 can be formed of other materials, such as, for example, synthetic leather, plastic, other polymeric materials, composite materials, rubber, and combinations thereof. The binding 33 can be formed of one or more colors or textures, which can match or differ from the color and texture of the front and back portions 12 and 14. The binding 33 can also be formed to be stiffer and/or harder than the material forming the front and back portions to further strengthen or stiffen particular regions of the ball glove 10. The binding can be formed of one or more pieces or layers.
The front portion 12 covers and protects the palm-side of the user's hand from impact with the ball. The back portion 14 supports the front portion 12 and protects the backside of the user's hand. The front and back portions 12 and 14 are made of a pliable, durable, and relatively soft material, preferably leather. In alternative preferred embodiments, the front and back portions 12 and 14 can be made of other materials, such as, for example, artificial leather, composite leather, rubber, plastic, other polymers and combinations thereof. The front and back portions 12 and 14 can including a binding 42
The webbing 16 is a generally flat structure that is connected, and preferably stitched and/or laced, to the front and back portions 12 and 14 between the first finger stall 20 and the thumb stall 28. The webbing 16 provides the ball glove 10 with a large catching surface for cradling a ball that is caught. The webbing 16 also provides the ball glove 10 with a surface for absorbing the initial impact of a ball being caught, reducing impacts directly to the player's hand within the glove.
The finger stalls 20-26 and the thumb stall 28 are elongate cavities adapted for receiving the fingers and thumb of the user. Each finger stall 20-26 and thumb stall 28 includes a front stall portion 34 of the front portion 12 and a back stall portion 36 of the rear portion 14. Each finger stall 20-26 and thumb stall 28 also includes a distal region 38 and a proximal region 40. The front and back stall portions 34 and 36 are coupled to each other, preferably through the plurality of weltings 30, lacings 32 and stitchings. Alternatively, the front and back stall portions 34 and 36 can be connected through other means, such as, for example, stitching only, bonding, other fasteners or molding. In order to facilitate the fielding of balls during play, the ball glove 10 is typically larger than the hand of the user. In particular, the finger and thumb stalls 20-28 are typically significantly longer than the length needed to accommodate the user's fingers and thumb.
As shown by
The spin reduction texture 52 increases the static coefficient of friction of the surface upon which it is applied, such as the front surface 58 of webbing 16. As a result, the increased coefficient of friction caused by the spin reduction texture 52 facilitates the player's ability to field, grasp and retrieve a hit, pitched or thrown ball. The spin reduction texture 52 with its increased coefficient of friction can reduce the spin of a hit, pitched or thrown ball more quickly that a ball glove front portion without spin reduction texture.
As shown by
The increase in the static coefficient of friction of the webbing 16 a ball glove having the spin reduction texture 52 compared to a ball glove webbing without spin reduction texture was measured in a static coefficient of friction test. The static coefficient of friction test was modeled after ASTM Standard D 1894-14 entitled “Standard Test Method for Static and Kinetic Coefficients of Friction of Plastic Film and Sheeting” promulgated by ASTM International located at 100 Barr Harbor Drive, West Conshohocken, Pennsylvania 19428-2959. Referring to
A total of 6 test skids or sleds 112 with separate test specimens on each sled 112 were prepared. The 6 separate test specimens were obtained from the first and second sets 102 and 104 of test specimens 100. The sleds 112 with the first and second sets 102 and 104 of specimens were pulled by a pulling device 118 and a cord 120 of a fixed length across the sheet 116 on the runway 114 at a speed of 152.4 mm per minute for a total distance of 200 mm. The initial force to start sled movement and the average force from the 25 mm distance to the 175 mm distance is recorded. The pulling device 118 can include a force-measuring device 122 capable of measuring frictional force to +/−5% of its value. The force-measuring device 122 can be a spring gage, a universal testing machine, or a strain gage. In the coefficient of friction test performed by ATI, the force-measuring device 122 was a Shimpo Instruments force measuring gauge, Model Name FGV-XY, with an accuracy of +/−0.2% (well below the 5% range of the ASTM Std.). The sled weight is then divided into the force values (force values divided by the sled weight) to obtain the Static and Kinetic Coefficient of Friction values at the respective sled positions.
The results identified from testing the static coefficient of friction of 6 test specimens 100 discussed above in light of ASTM D1894-14 are shown below in Table 1.
The static coefficient of friction test results demonstrate an increase in the coefficient of friction values of the first set 102 of specimens 100 that include the spin reduction texture 52 compared to the second set 104 specimens 100 that did not include the spin reduction technology. The measured average static coefficient of friction of the first set 102 of test specimens was more than 5 percent higher than the measured average static coefficient of friction of the second set 104 of test specimens. This measured increase in static coefficient of friction values between the first set 102 of test specimens 100 compared to the second set 104 of test specimens 100 indicates that relative movement of a high-end leather baseball within a ball glove 10 having the spin reduction texture 52 will be less, or more quickly stopped, than relative movement of high-end leather baseball within a ball glove formed without the spin reduction technology. Accordingly, the coefficient of friction values will be increased in a ball glove having spin reduction texture versus a ball glove formed without the spin reduction texture. The increased coefficient of friction will resist movement and/or rotation of a high-end leather baseball within a ball glove to a greater extent than ball gloves formed without the spin reduction texture. Accordingly, the coefficient of friction test results indicate that ball gloves incorporating the spin reduction texture will facilitate a ballplayer's ability to catch, grasp and retrieve a hit, pitched or thrown ball because the spin reduction texture on the front portion of the ball glove will inhibit relative movement of the ball within the ball glove. A spinning hit or thrown ball will stop spinning, rotating or moving within the ballplayer's glove quicker with the spin reduction technology of the present application than a ball glove formed without spin reduction technology. As a result, ball players, such as infielders, can more quickly catch and retrieve the ball from his or her ball glove including the spin reduction texture than a ball glove formed without spin reduction texture. A ballplayer's ability to retrieve a fielded ball quickly from his or her ball glove can be critical in determining the outcome of a baseball or softball play.

A ball carrying a sensor can also be used to measure the advantages of the spin reduction texture 52 on the front or palm portion 12 of the ball glove 10. The sensored or smart ball can be used in conjunction with the ball glove 10 or with a set of ball gloves (with some ball gloves incorporating the present invention, and others being existing ball gloves without the spin reduction technology or texture). The sensored or smart ball can be a baseball, a fast pitch softball or a slow pitch softball. As shown by
In one implementation, the core 222 is formed as a solid, homogeneous, one-piece spherical body. In another implementation, the core 222 can be formed from two or more layers of materials, such as two or more rubber compositions.
The at least one layer of yarn 224 surrounds the core 122. The yarn 224 comprise at least one layer single or multiply yarn windings. Such yarn windings may be single ply, five ply, three ply or other numbers of ply values or combinations. The yarn windings may be formed of wool, synthetic yarn, synthetic recycled fibers (such as from used carpet), and fibers or combinations thereof. Synthetic yarn may be formed from polyester, rayon, acrylic, other synthetic materials and combinations thereof. In one implementation, the at least one layer of yarn 224 comprises five ply yarn windings, wherein the yarn can be 85% wool and 15% synthetic fibers. In other implementations, other combinations percentages of wool and synthetic fibers may be employed.
The cover assembly 226 comprises one or more panels surrounding the at least one yarn layer 224 and providing an outer cover to the ball 220. In the example illustrated, cover assembly 226 comprises two cover panels 232 connected to one another by a stitching 234 along at least one seam 236. The seam 236 is generally flush with the outer diameter the ball 220. In other implementations, one seam 236 may be raised slightly raised with respect to central regions of panels 232. The seam 236 may be formed by abutted, overlapped, curved or inverted edges of the cover panels 232. The stitching 234 joining the panels 232 along the seam 236 is formed from a high tensile strength thread, such as Kevlar thread material. In other implementations, other high tensile strength thread materials may be utilized.
The panels 232 comprise panels formed from a durable high-strength material, such as natural leather. In other implementations, the panel 232 may be formed from other durable material such as split leather, synthetic leather, polyurethane, a polyvinyl chloride (PVC), other polymeric materials, or combinations thereof. Although the panels 232 are illustrated as each having the same shape, in other implementations, panel 232 may have dissimilar shapes with respect to one another. In other implementations, the ball 220 may utilize more than two panels 232.
In one implementation, ball has an initial compression value obtained in accordance with ASTM Standard Test Method F1888-09 and a second compression value obtained in accordance with ASTM Standard Test Method F1888-09 after the baseball has undergone at least 60 impacts of approximately 60 mph against a strike plate, the second compression value being greater than 75% of the initial compression value. In one implementation, the core 222 has a diameter of less than 2 inches. In one implementation, the ball 220 has a circumference of less than 12.5 inches. In one implementation, the ball 220 has a circumference of less than 12 inches. In another implementation, the ball 220 has a circumference greater than 9.5 inches, such as a softball. In other implementations, the ball 220 has a circumference of less than or equal to 9.5 inches any weight of less than 5.5 ounces, such as a baseball. In other implementations, the ball 220, but for the electronics 228, may have other configurations.
The electronics 228 are carried by the ball 220 and perform one or more functions based upon sensed motion or travel of the ball 220. In the example illustrated, the electronics 228 are located inwardly of cover panels 232. In the example illustrated, the electronics 228 are located inwardly of the at least one layer of yarn 224. In the example illustrated, the electronics 228 are located at least partially within the core 222. In the specific example illustrated, the electronics 228 are located at a center point or centered portion of the ball 220 within the core 222. In one implementation, the electronics 228 are encapsulated within materials of the core 222. In another implementation, the electronics 228 are located within cavity 227 within the core 222. Because the electronics 228 are centered within the ball 220, the electronics 228 are less likely to impact weight distribution characteristics and the feel of the ball 220.
In other implementations, the electronics 228 may located at other locations, such as: in an un-centered, eccentric position within the core 222; in a cavity or depression extending from an exterior surface of the core 222 into the core 222; centrally located within the one or more windings of the one or more of layers of yarn 224; in a cavity or depression extending from an exterior surface of the at least one layer of yarn 224 into the at least one layer of yarn 224; and/or in a cavity or void formed between the core 222 and yarn layer(s) 224 are between yarn layer(s) 224 and cover panels 232.
Battery 238 comprises a power storage device to store power for use by sensor 240 and data output device 242. In one implementation, battery 238 comprises a one-use battery. In another implementation, battery 238 comprises a rechargeable battery. For example, in one implementation, battery 238 is rechargeable in a wired fashion through a plug or port in the ball 220. In another implementation, battery 238 is rechargeable in a noncontact fashion. In one implementation, battery 238 may be inductively charged or recharged. In one implementation, the ball 220 is alternatively configured to provide access to battery 238 for removal and replacement of battery 238.
Motion sensor 239 comprises one or more sensors to sense motion of the ball 220 facilitating a determination of a speed, travel velocity or linear velocity of the ball 220. Motion sensor 239 facilitates feedback regarding the speed of the ball 220. Motion sensor 239 provides raw sensed motion data in the form of sensed acceleration along different axes. For purposes of this disclosure, the term “raw sensed motion data” comprises data or signals directly outputted or determined by sensor 240. For purposes of this disclosure, the term “sensed motion data” or “motion data” encompasses at least one of raw sensed motion data and data that has been generated based upon or using the raw sensed motion data, such as data that has been derived from the raw sensed motion data. By sensing parameters from which the travel speed of the ball 220 may be identified or determined, the ball 220 provides feedback for evaluation of a hit, thrown or pitched ball. In one implementation, motion sensor 239 comprises one or more accelerometers 246, which provide acceleration signals or data from which the speed of the ball 220 is determined. By allowing the speed of the ball 220 to be determined, sensor 240 facilitates evaluation of a hit ball or of a pitch, such as a fastball pitch and a changeup pitch.
Data output device 242 comprises one or more devices to externally communicate the motion information or motion data sensed by sensor 240. In one implementation, data output device 242 comprises a device to wirelessly transmit signals representing the sensed motion information. For example, in one implementation, data output device 242 comprises a Bluetooth device. In another implementation, data output device 242 comprises a Wi-Fi or other radiofrequency transmitter. In another implementation, data output device 242 comprises an active read/write RFID tag, which is written upon with data sensed by sensor 240, wherein device 242 actively transmits signals from the tag. In yet another implementation, data output device 242 comprises a passive read/write RFID tag, which is written upon with data sent by sensor 240, wherein device 242 is passively read by an external radiofrequency device reader. In another implementation, data output device 242 comprises an infrared or other optical communication device. In yet other implementations, data output device 242 may comprise other devices that communicate the sensed motion data to recipients external to the ball 220 in a wireless fashion.
In one implementation, the ball 220 communicates the sensed motion data to recipient(s) external to the ball 220 in a wireless fashion, wherein the external recipient comprises a portable electronic device such as a smart phone, a flash memory reader (IPOD), a cell phone, a personal data assistant, a laptop computer, a tablet or netbook computer and the like. In one implementation, electronics 228A carries out at least some data modifications and/or analysis prior to the data being externally transmitted to the portable electronic device. For example, electronics 228A may carry out some analysis, data derivations or data compression on the sensed motion information or on derived results of the sensed motion information prior to transmitting the modified, derived and/or compressed data to the portable electronic device. In other implementations, electronics 228A may transmit, in real time, raw signal data or raw sensed motion data directly from sensor 240 to the portable electronic device, wherein the portable electronic device performs analysis or further data derivation using the raw sensed motion data. In such an implementation, because the processing power is more greatly provided by the portable electronic device, rather than electronics 228A of the ball 220, the cost of the ball 220 may be kept low.
As will be described hereafter with respect to other figures, in some implementations, data output device 242 may additionally or alternatively communicate the sensed motion data in other fashions. For example, in one implementation, data output device 242 comprises a plug-in or port by which the sensed motion data may be communicated externally from the ball 220 in a wired fashion.
Referring to
Although sensor 240 is illustrated as comprising one or more accelerometers 246 and one or more angular rate gyros or gyrometers 248, in other implementations, sensor 240 may additionally or alternatively comprise a temperature sensor, a pressure sensor and/or a magnetometer. In some implementations, sensor 240 may additionally or alternatively comprise a global positioning system (GPS) antenna or sensor.
Memory 254 comprises one or more non-transient computer-readable medium or persistent storage devices carried within ball 220 and accessed for reading and/or writing by controller 256 and data output device 242A and/or data output device 242B. In one implementation, memory 254 includes computer-readable instructions or code for directing the operation of controller 256. In one implementation, memory 254 additionally or alternatively stores sensed motion data. The sensed motion data stored by memory 254 comprises both the raw sensed motion data and sensed motion data that has been derived from the raw sensed motion data.

The slopes of the linear regression lines of the data acquired from the baseballs caught from the glove with the spin reduction texture 52 from Player 1, Player 2 and the combination of Players 1 and 2 were −2.3108, −2.735, and −2.5113, respectively. Further, the reduction in the angular rotation or spinning of the baseball when caught with the ball glove having the spin reduction texture 52 was approximately 544 rpm, 630 rpm and 582 rpm over a 25 ms interval following initial impact of the ball with the ball glove. Conversely, the reduction in the angular rotation or spinning of the baseball when caught with the stock ball glove not having the spin reduction texture 52 was approximately 496 rpm, 363 rpm and 410 rpm over 25 ms intervals following initial impact of the ball with the ball glove. Accordingly, the ball glove having the spin reduction texture 52 produced a reduction in the angular rotation or spinning of the baseball of at least 540 rpm over a 25 ms interval following initial impact of the ball with the ball glove, when the ball was thrown at a velocity of within the range of 50-60 mph. Additionally, the ball glove having the spin reduction texture 52 produces a linear regression line having a slope of at least −2.3 from data acquired from catching baseballs thrown at a speed within the range of 50-60 mph. As a result, the sample testing indicates that glove 10 and other gloves provided with a spin reducing texture can more quickly reduce the spin of the ball in the glove, enhancing a ballplayer's ability to catch or field, grasp and retrieve a pitched, thrown or hit ball from the ball glove. By inhibiting or reducing the ball's spin upon fielding or catching a ball, the spin reducing texture of the ball glove can make the fielded ball easier to grasp and retrieve from the ball glove.
In the example illustrated, ball glove 410 is similar to ball glove 10 described above except that ball glove 410 comprises three different spin reducing textures 452-1, 452-2 and 452-3 (collectively referred to as textures 452). Textures 452 provide different regions on the palm side of ball glove 410 with different spin reducing and ball gripping characteristics. In the example illustrated, spin reducing texture 452-1 extends on the palm side of glove 410 below each of the front stall portions 34 of the ball glove 410 to the hand opening or mouth 455 of the glove 410. Spin reducing texture 452-2 extends on the front stall portions 34 of ball glove 410 including at least the front stall portions 34 of finger stalls 20, 22 and thumb stall 28. Spin reducing texture 452-3 extends on the front side 458 of webbing 416.
In the illustrated example, spin reduction texture 452-3 has pattern of diamond-shaped raised projections and/or recesses similar to the pattern shown in
In other implementations, spin reducing textures 452 may have other patterns, such as any of the other pattern shown in
While the preferred embodiments of the present invention have been described and illustrated, numerous departures therefrom can be contemplated by persons skilled in the art. Therefore, the present invention is not limited to the foregoing description but only by the scope and spirit of the appended claims.
