This application claims the priority benefit of Taiwan application serial no. 107144650, filed on Dec. 11, 2018. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
The disclosure relates to a sporting goods, in particular to a golf ball.
Along with the swift technological advancement, the material culture and the quality of life also continue to arise while leisure time exercise becomes a trend. Golf sport, once taken as a sport form exclusive to the nobles, is now popularized by the trend of leisure time exercise. The participants of golf sport can be seen at all ages, and the enthusiasts include all genders. Furthermore, the people who participate in golf sport have been rapidly increasing in recent years.
During a golf competition, it is required to have an accurate judgment of the location of a hit golf ball to avoid a waste of time looking for the golf ball. It is in light of this that some golf balls are designed to have a built-in chip or an antenna to transmit signals to an external device via active or passive means to fulfill the purpose of detecting the location of the golf ball. However, the chip and the antenna built in a golf ball are prone to be damaged by the impact force of the hit, and also the center of gravity of a golf ball can be altered by the configuration of the chip and the antenna and thus deviates from the mass center, causing an unpredictable flight path.
The disclosure provides a golf ball which provides a location detection function and has great reliability.
A golf ball of the disclosure includes at least a layer of ball shell, at least a layer of ball core, and an antenna layer. The ball core is provided in the ball shell. The antenna layer is provided between the ball shell and the ball core or on an outer side of the ball shell. A material of the antenna layer includes a conductive material having fluidity or ductility which auto-recovers and does not break after a hit.
In an embodiment of the disclosure, the antenna layer is provided on a surface of the ball shell or a surface of the ball core.
In an embodiment of the disclosure, the antenna layer is provided symmetrically to a ball center of the golf ball.
In an embodiment of the disclosure, the golf ball includes at least two chips, which are provided between the ball shell and the ball core or on the outer side of the ball shell and are electrically connected to the antenna layer.
In an embodiment of the disclosure, the at least two chips are provided symmetrically to a ball center of the golf ball.
In an embodiment of the disclosure, the at least two chips are provided on a surface of the ball shell or a surface of the ball core.
In an embodiment of the disclosure, the at least a layer of ball shell includes a plurality of layers, and the two chips are provided between adjacent two layers of the ball shell.
In an embodiment of the disclosure, the at least a layer of ball core includes a plurality of layers, and the two chips are provided between adjacent two layers of the ball core.
In an embodiment of the disclosure, the at least a layer of ball shell includes a plurality of layers, and the antenna layer is provided between adjacent two layers of the ball shell.
In an embodiment of the disclosure, the at least a layer of ball core includes a plurality of layers, and the antenna layer is provided between adjacent two layers of the ball core.
In an embodiment of the disclosure, the material of the antenna layer includes a liquid metal.
In an embodiment of the disclosure, the material of the antenna layer includes metal powder.
In an embodiment of the disclosure, the material of the antenna layer includes an electrically conductive adhesive having ductility.
Based on the above, in the golf ball of the disclosure, the antenna layer is made of a conductive material having fluidity or ductility, which produces a buffering effect when the golf ball takes an impact force of a hit, and maintains or restores structural integrity.
In order to make the aforementioned and other features and advantages of the disclosure more comprehensible, several exemplary embodiments accompanied with figures are described in detail below.
According to the present embodiment, a material of the antenna layer 130 includes a conductive material having fluidity or ductility, which provides a buffering or an auto-recovery effect when the golf ball takes an impact force of a hit, and maintains or restores the structural integrity after the golf ball is deformed by the impact. Such design avoids the conductivity and antenna features of the antenna layer 130 and the function of the antenna from being affected by structural deformation or fracture caused by the impact force, thereby increasing the durability and reliability of the golf ball 100.
A conductive material having fluidity may be liquid metal, metal powder, electrically conductive adhesive, etc., instead of a general solid conductive material. To be more specific, a conductive material having fluidity may be selenium-graphite powder, silver paste, or special electrically conductive adhesive, but the disclosure is not limited thereto.
To put it in detail, the antenna layer 130 of the present embodiment is disposed on an inner surface 110a of the ball shell 110 by printing, spraying, or coating, and then covers the outside of the ball core 120 together with the ball shell 110. Furthermore, the antenna layer 130 is provided symmetrically to a ball center C of the golf ball 100 to avoid a change in a center of gravity of the golf ball 100 into a location not as expected due to the addition of the antenna layer 130.
Also, when the golf ball 100 takes a hit, the ball center C of the golf ball 100 generally takes a greater impact. In light of this, instead of being provided at or near the ball center C of the golf ball 100, the antenna layer 130 is provided between the ball shell 110 and the ball core 120 as stated above to avoid the antenna layer 130 from taking excessive impact and being damaged.
Referring to
In the present embodiment, the two chips 140 are provided symmetrically to the ball center C of the golf ball 100 to avoid a change in the center of gravity of the golf ball 100 into a location not as expected due to the addition of the chips 140. In other embodiments, more chips 140 may be disposed and the chips 140 are also provided symmetrically to the ball center C of the golf ball 100. The disclosure puts no restriction on the number of the chips.
Also, when the golf ball 100 takes a hit, the ball center C of the golf ball 100 generally takes a greater impact. In light of this, instead of being provided at or near the ball center C of the golf ball 100, the chips 140 are provided between the ball shell 110 and the ball core 120 as stated above to avoid the chips 140 from taking excessive impact and being damaged while also protecting integrity of the ball core.
Similar to the configuration of
The disclosure does not put restriction on a material of the ball shell 110. In any of the aforementioned embodiments, the outermost layer of the ball shell 110 may be a paint layer. In addition, the antenna layer 130 and the chips 140 may be disposed on the outer side of the outermost ball shell to be located at the outer surface of the golf ball.
To sum up the above, in the golf ball of the disclosure, the antenna layer is made of a conductive material having fluidity or ductility which provides a buffering or an auto-recovery effect when the golf ball takes an impact force of a hit, and maintains or restores the structural integrity after the golf ball is deformed by the impact. Also, the antenna layer and the chip are provided symmetrically to the ball center of the golf ball to avoid a change in the center of gravity of the golf ball into a location not as expected due to the addition of the antenna layer and the chip. In addition, instead of being provided at or near the ball center of the golf ball, the antenna layer and the chip are provided between the ball shell and the ball core, thereby avoiding the antenna layer and the chip from taking excessive impact and being damaged while also protecting integrity of the ball core.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the disclosure without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the disclosure covers modifications and variations of this disclosure provided they fall within the scope of the following claims and their equivalents.
