Abstract
Description
- This Application claims priority from Japanese Patent Application No. 2015-131623 filed Jun. 30, 2015, which is incorporated herein by reference in its entirety.
- The present invention relates to a golf ball with a built-in integrated circuit (IC) chip such as a radio-frequency identification (RFID) chip.
- In order to record information about golf balls, such as the material, the location of production, and the production date in the golf balls, attempts have been made to incorporate an IC chip in golf balls.
- For example, JP 2013-154176 A discloses that an RFID circuit and an antenna connected thereto are formed on the surface of the cover of a golf ball by using a conductive ink in order to prevent damage to the built-in IC chip that may occur when the golf ball is hit.
- To transmit and receive information by wireless communication, a metal antenna is usually connected to a silicon IC chip. Small IC tags with an IC chip including a built-in antenna are currently being sold; however, because the antenna of such an IC tag is short, the communication range may be short when it is incorporated in golf balls, and as a result, the IC tag cannot be easily read by a reader. Accordingly, in incorporating such an IC tag in a golf ball, it is necessary to connect a long antenna to the IC chip. However, because a golf ball is greatly deformed at the moment it is hit, a problem may arise in that the bonding portion between the IC chip and the antenna is particularly easily damaged, and thus, communication may very soon fail.
- In order to solve the above-described problem, an object of the present invention is to provide a golf ball with a built-in IC chip capable of preventing communication failure that may occur due to damage on the IC chip incorporated in the golf ball caused by impact from hitting of the ball.
- In order to achieve the above-described object, a golf ball with a built-in IC chip according to the present invention includes: a core located in the center of the golf ball; a cover surrounding an outside of the core; an IC tag arranged between the core and the cover, the IC tag further including an IC chip and a first antenna directly connected to the IC chip; and a second antenna of which a part is disposed near the IC tag.
- It is not necessary for the second antenna and the IC tag to be in physical contact with each other. Preferably, the part of the second antenna disposed near the IC tag may be located within a distance of at most 1 mm from the IC tag. The second antenna may be disposed over at least a half of the outer periphery of the IC tag. The second antenna may be arranged over at least a half of the circumference of the golf ball. The size of the IC chip may be at most 5 mm.
- As described above, according to the present invention, a part of the second antenna being disposed near the IC tag which includes the built-in first antenna and is arranged between the core and the cover of the golf ball, and thus, the second antenna functions as an antenna for the IC chip via the first antenna in the IC tag although the second antenna is not physically connected with the IC chip in the IC tag for electrical connection. Accordingly, the communication distance of the IC tag can be dramatically extended compared with the case of using the IC tag only. In addition, the second antenna is physically coupled with neither the IC chip nor the first antenna, and thus, there is no case in which a bonding portion between the second antenna and the IC chip is damaged due to the hitting of the golf ball, resulting in preventing communication failure.

boost antenna 40 is disposed near theRFID tag 30, particularly in acenter portion 40 a thereof. The term “disposed near” herein refers to a state in which theboost antenna 40 is disposed near, close to, proximately to, in the vicinity of, or around theRFID tag 30, including a state in which theboost antenna 40 and theRFID tag 30 are not in physical contact for electrical connection, but theboost antenna 40 and theRFID tag 30 may be in non-electrical contact. Preferably, the RFID tag and theboost antenna 40 are arranged so that the distance therebetween is at most 1 mm. - By arranging the
boost antenna 40 in relation to theRFID tag 30 in the above-described manner, even if a strong impact has been applied to thegolf ball 1 due to hitting with a golf club, communication failure that may occur in the conventional technique due to damage on the connection portion between the IC chip and the antenna can be prevented because theIC chip 32 of theRFID tag 30 and theboost antenna 40 are not physically connected for electrical connection. - The

For the conductive yarn, yarns including a core constituted by fibers such as nylon fiber and polyester fiber plated with metals such as silver and copper can be used. The percentage content of the metal constituting the conductive yarn is not particularly limited except that the content is high enough to secure the conductivity. Specifically, for example, the percentage content of the metal is preferably in a range of 10 to 70% by weight. In addition, in order to securely position the center of gravity point of thegolf ball 1 in the center of the ball, it is preferable for the composition of the metal yarn and the conductive yarn to be a composition with which the specific gravity of theboost antenna 40 becomes the same as the specific gravity of the layer in which theRFID tag 30 and the like are arranged. - The diameter of the boost antenna 40 (the metallic yarn and the conductive yarn) is not particularly limited, and an upper limit thereof is preferably 1.5 mm or less, more preferably 1.0 mm. A lower limit thereof is preferably 0.1 mm or more, more preferably 0.3 mm or more.
- The

It is preferable that bothside portions entire boost antenna 40, theboost antenna 40 is arranged over about ¾ of the circumference of thegolf ball 1 or the core 10 inFIG. 3 . However, the present invention is not limited to this. Specifically, it is preferable to arrange theboost antenna 40 on a portion that corresponds to at least a half of the circumference of thegolf ball 1 or thecore 10. With the above-described configuration, the communication range is extended, and communication with theRFID tag 30 can be performed by using a reader at any location on thegolf ball 1, i.e., even at a location on the golf ball on the opposite side of theRFID tag 30. - The shape or the arrangement of both
side portions side portions - The present invention can be employed in a golf ball having a multi-piece structure. For example, in a configuration in which the golf ball includes an
intermediate layer 50 arranged between the core 10 and thecover 20 as illustrated inFIG. 4 , it is preferable to embed theRFID tag 30 in agroove 52 formed on the surface of theintermediate layer 50. In addition, it is preferable to arrange theboost antenna 40antenna 40 so that the bothside portions center portion 40 a disposed near theRFID tag 30 extend in mutually opposite directions along the surface of theintermediate layer 50. The number of theintermediate layer 50 is not limited to one as illustrated inFIG. 4 , and alternatively, a plurality ofintermediate layer 50 may be arranged. In the golf ball having the multi-piece structure, if a plurality of intermediate layers is provided, it is preferable to arrange the RFID tag and the boost antenna on the surface of the layer located in an inside of the layer in the outermost shell (i.e., the cover), and thereby a sufficient communication distance can be secured. In terms of the diameter of the golf ball, theboost antenna 40 is arranged on an imaginary sphere having a diameter of preferably 42 mm or less, more preferably 40 mm or less and having the same center as the golf ball. Also, theboost antenna 40 is arranged on a sphere having a diameter of preferably 20 mm or more, more preferably 30 mm or more. - The core 10 can be formed primarily from rubber. For the rubber (base material rubber) used as the main component, a wide variety of rubbers can be used. Examples of such a rubber include, but are not limited to, polybutadiene rubber (BR), styrene-butadiene rubber (SBR), natural rubber (NR), polyisoprene rubber (IR), polyurethane rubber (PU), and silicone rubber.
- In addition to the base material rubber that is the main component, optional components such as co-crosslinking agent, crosslinking agent, filler, age resistor, isomerization agent, peptizer, sulfur, and organosulfur compound can be added to the
core 10. As the main component, a resin may be used instead of the rubber. Specifically, a thermoplastic elastomer, an ionomer resin, or a mixture thereof can also be used, for example. - The hardness of the
core 10 is not particularly limited, and an upper limit thereof is preferably 60 or less, more preferably 50 or less, yet more preferably 40 or less, by the Shore D hardness. A lower limit of the hardness of thecore 10 is preferably 20 or more, more preferably 30 or more, by the Shore D hardness. - The
core 10 has a substantially spherical shape. An outer diameter of thecore 10 is preferably 42 mm or less, more preferably 41 mm or less, yet more preferably 40 mm or less. Considering that the repulsion of the golf ball may be lowered if the outer diameter of thecore 10 is too small, a lower limit of the outer diameter of thecore 10 is preferably 5 mm or more, more preferably 15 mm or more, yet more preferably 25 mm or more. Thecore 10 is a solid core as illustrated inFIG. 3 . However, thecore 10 is not limited to this, and a hollow core may be used. In addition, thecore 10 includes one layer as illustrated inFIG. 3 . However, thecore 10 is not limited to this and may be constituted by a plurality of layers including a center core and one or more surrounding layers. - The
cover 20 can be formed by using a material that uses, but is not limited to, an ionomer resin, a polyurethane thermoplastic elastomer, thermosetting polyurethane, and a mixture thereof as the main component. For the above-described main component, a two-component curing type polyurethane resin can also be used. Further, in addition to the main component described above, other thermoplastic elastomers, a polyisocyanate compound, fatty acid or a derivative thereof, a basic inorganic metal compound, a filler, and the like can be added to thecover 20. - For the ionomer resin, a resin including, but not limited to, the following (a) component and/or (b) component as the base resin can be used. In addition, the following (c) component can be added to the base resin. The (a) component is an olefin-unsaturated carboxylic acid-unsaturated carboxylic ester ternary random copolymer and/or a metal salt thereof, the (b) component is an olefin-unsaturated carboxylic acid binary random copolymer and/or a metal salt thereof, and the (c) component is a thermoplastic block copolymer including a polyolefin crystalline block and a polyethylene/butylene random copolymer.
- The hardness of the material constituting the
cover 20 is not particularly limited, and a lower limit thereof is preferably 50 or more, more preferably 55 or more, by the Shore D hardness. An upper limit thereof is preferably 75 or less, more preferably 70 or less, yet more preferably 65 or less, by the Shore D hardness. - A lower limit of the thickness of the
cover 20 is, but is not limited to, preferably 0.2 mm or more, more preferably 0.4 mm or more. An upper limit of the thickness of thecover 20 is, but is not limited to, preferably 4 mm or less, more preferably 3 mm or less, yet more preferably 2 mm or less. A plurality of dimples (not illustrated) is formed on the surface of thecover 20. The size, the shape, the number, and the like can be appropriately designed according to the aerodynamic performance desired for the golf ball. - For the material of the
intermediate layer 50, an intermediate layer having a core-like function may be formed by using the same material as that of the core described above, and alternatively, an intermediate layer having a cover-like function may be formed by using the same material as that of the cover described above. In a configuration including a plurality of intermediate layers, a first intermediate layer having a core-like function and a second intermediate layer having a cover-like function, for example, may be provided. - It is preferable that the golf ball constituted by the
core 10, thecover 20, and the optionalintermediate layer 50 described above have a predetermined ball hardness. The ball hardness refers to a deformation amount of the golf ball when loads from the initial load of 98 N to the final load of 1275 N are applied to the golf ball (i.e., an amount of compressive deformation). The unit is expressed in “mm”. The rate of compression is 10 mm/s. For this ball hardness (deformation amount), the smaller the numerical value thereof, the harder the golf ball, and the higher the numerical value thereof, the softer the golf ball. In addition, the deformation amount affects the hitting feeling felt by the golfer when the golfer takes a shot, the durability, and the like. Accordingly, it is preferable that a lower limit of the deformation amount be 1.5 mm or more and an upper limit thereof be 5.0 mm or less. - Next, an embodiment of a method of producing the
golf ball 1 incorporating theRFID tag 30 and theboost antenna 40 described above will be described. - First, the
core 10 is molded by a known method for molding a core of a golf ball. Specifically, the core 10 can be obtained by a method in which a material including a base material rubber is kneaded by using a kneader, and then the kneaded material is molded by pressurized vulcanization in round molds. Thegroove 12 for the RFID tag formed on the surface of the core 10 can be formed by using the round molds or by excavating the surface of the molded product molded in molds by using excavation tools. TheRFID tag 30 incorporating a commercial antenna, for example, is arranged in thegroove 12. - As the
boost antenna 40, a metal yarn or a conductive yarn is arranged on the surface of thecore 10. In arranging them, theboost antenna 40 is arranged so that theboost antenna 40 surrounds the outer periphery of theRFID tag 30 over at least the half of the outer periphery. It is desirable that the distance between theboost antenna 40 and theRFID tag 30 be 1 mm or less. Of course, theboost antenna 40 and theRFID tag 30 may be partially in contact with each other. - Next, the
cover 20 is formed by an injection molding method, for example. Specifically, the core 10 in which theRFID tag 30 and theboost antenna 40 have been arranged is placed into the mold for the cover in the center of the mold, then the material of the cover is introduced into the mold by injection so that the material covers thecore 10, and thereby thecover 20 can be formed. In the above-described manner, the golf ball incorporating the RFID tag and the boost antenna can be produced. - Note that if an active RFID tag incorporating a battery cell is used, it is preferable that the cover be formed by introducing a two-component curing type polyurethane resin into the mold for the cover instead of using an injection molding method. Failure of the battery cell incorporated in the RFID tag due to heat can be prevented by using the two-component curing type polyurethane resin.
- A method of producing the golf ball having the multi-piece structure including the
intermediate layer 50 will be described. If the intermediate layer is formed by the material of the core, a known molding method for molding a multi-layer structured solid core can be employed in molding the intermediate layer. For example, thecore 10 is obtained by the above-described method, the obtained core is used as the center core, further, the material of the core is kneaded by using a kneader, the kneaded material is molded into a sheet-like shape, then the center core is covered with the sheet and the resulting material is molded by pressurized vulcanization in round molds, and thereby a product including theintermediate layer 50 constituted by the material of the core and formed around the outer periphery of thecenter core 10 can be obtained. Thegroove 52 for the RFID tag on the surface of theintermediate layer 50 can be formed by using the above-described round molds or by excavating the surface of the molded product molded in molds by using excavation tools. TheRFID tag 30 is arranged in thegroove 52 and theboost antenna 40 is arranged on the surface of theintermediate layer 50. Thecover 20 is formed by an injection molding method and the like, and thereby the golf ball having the multi-piece structure incorporating the RFID tag and the boost antenna can be produced. - Three golf balls having the configurations shown in Table 1 were prepared for the Example of the present invention and the Comparative Example, and tests were carried out for measuring the durability of the golf balls and the performance of reading the built-in RFID tag. For the RFID tags, Monza 5 (frequency band: UHF) of Hitachi Chemical Co., Ltd. was used. All of the RFID tags were a flat square body with the dimensions shown in Table 1. For the boost antenna, a conductive yarn (diameter: 0.7 mm) composed of 83% nylon and 17% silver was used. The boost antenna was disposed near the RFID tag with the center of the RFID tag surrounding the RFID tag on three edges of the RFID tag, within the distance from the RFID tag of 1 mm or less. The boost antenna was arranged by 39.3 mm on the diameter of the golf ball and along the half of the circumference of the golf ball (core).
- Note that RFID tags similar to those in the Examples were used in the Comparative Examples including a configuration in which no boost antenna was arranged (Comparative Example 1), a configuration in which neither the RFID tag nor the boost antenna was arranged (Comparative Example 2), and a configuration in which an external antenna-bonded
IC chip 60 to which an external antenna 66 (material: copper) formed with a ring-like shape and having the outer diameter of 11 mm was bonded to acommercial IC chip 62 including no built-in antenna by using a connection material constituted by the same material as that of the external antenna, instead of using an RFID tag (Comparative Example 3) as illustrated inFIG. 5 . Tests similar to those for the Examples were carried out for the Comparative Examples. The material and the composition of the core and the cover of the golf balls were the same among Examples 1 to 3 and Comparative Examples 1 to 3. Rubber was used as the material of the core, and an ionomer resin was used as the material of the cover. The hardness of the cover was D56. -

The ball initial velocity was measured by the measurement method provided in the golf ball initial velocity rules by using an initial velocity measurement device of the same type as the drum rotation type initial velocity meter used by the United States Golf Association (USGA).
- For the communications distance in Table 1, AT-880 of ATID CO., LTD. was used as an RFID reader, and the distance from the golf ball by which the RFID tags were normally read, i.e., the distance from the golf ball to the RFID reader, was measured.
- For the COR durability in Table 1, the durability of the golf balls was evaluated by using ADC Ball COR Durability Tester of Automated Design Corporation (U.S.). The tester has a function for ejecting golf balls by air pressure and colliding them consecutively on two parallel installed metal plates. The velocity of incidence to the metal plates was 43 m/s. An average value of the number of times of ejections of the ball given until the ball was broken was used as the COR durability. In these test results, the average value refers to a value obtained by averaging the number of times of ejections given until all three balls ejected for each Example and each Comparative Example were broken.
- The RFID reading performance was examined, and as a result, the RFID was normally read for all the golf balls of Examples 1 to 3 and Comparative Example 1 until the balls were broken in the COR durability test. In contrast, in Comparative Example 3 in which an IC chip including no built-in antenna to which an external antenna was physically bonded, the RFID was not read in the 10th ejection of the balls, i.e., far earlier than the balls were to be broken in the COR durability test. As a result, it was shown that by providing the boost antenna disposed near the RFID tag incorporating an antenna, failure of communication with the RFID tag could be prevented even if the golf ball was hit hard. The durability of the golf balls per se incorporating the RFID tag and the boost antenna in their inside (Examples 1 to 3) were the same as those of common golf balls including neither the RFID tag nor the boost antenna (Comparative Example 2).
