DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] The following describes the embodiments disclosed in the present invention through specific examples. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various detailed descriptions in this specification can be modified and changed in various ways based on different perspectives and applications without departing from the idea of ​​the present invention. In addition, it should be noted in advance that the drawings of the present invention are merely schematic and are not drawn based on actual size. The technical contents related to the present invention will be described in more detail using the following embodiments, but the disclosed contents are not intended to limit the scope of protection of the present invention. In addition, the term "or" in this specification should be understood to include any one or more combinations of the relevant listed items according to the actual situation.

[0025] [First Example] 1 to 3 show a first embodiment of the present invention. This embodiment provides a spherical structure Z1 with a protrusion pattern. The spherical structure Z1 with a protrusion pattern according to this embodiment includes a sphere 1 and a plurality of block-shaped protrusions 3 formed in a serpentine pattern on the surface of the sphere 1, two of which face each other. Furthermore, the plurality of block-shaped protrusions 3 increase the air resistance when the sphere 1 is thrown, and increase the range of change in the flight path of a curveball.

[0026] In this embodiment, meandering ridges 2 are formed on the surface of the sphere 1, and the plurality of block-shaped protrusions 3 may be formed so that two of each ridge 2 faces the surface of the sphere 1. This increases air resistance.

[0027] Furthermore, the ridges 2 and the block-shaped protrusions 3 thereon in this embodiment may correspond to the positions of seams on a baseball. Each block-shaped protrusion 3 has an irregular shape, preferably an irregular pentagon. In addition, a narrow air passage 4 and a gradually expanding air passage 5 are formed so as to communicate between any two opposing block-shaped protrusions 3, which can disturb the air flow and increase air resistance.

[0028] Specifically, the block-shaped protrusion 3 has a top wall 30 and five side walls connected to the top wall 30, which are provided at an angle and are, in order, a first side wall 31, a second side wall 32, a third side wall 33, a fourth side wall 34, and a fifth side wall 35. The first side wall 31 is connected to the second side wall 32 and the fifth side wall 35, the fourth side wall 34 is connected to the fifth side wall 35 and the third side wall 33, and the second side wall 32 is connected to the first side wall 31 and the third side wall 33. Both the inner and outer opposing sides of each block-shaped protrusion 3 are the first side wall 31 and the fourth side wall 34, and the surface area of ​​the first side wall 31 is smaller than the surface area of ​​the fourth side wall 34, so that the narrow air passage 4 described above is formed between the two first side walls 31 of any two opposing block-shaped protrusions 3, and the gradually expanding air passage 5 described above is formed between the two second side walls 32 of any two opposing block-shaped protrusions 3.

[0029] The diameter of the sphere 1 in this embodiment is preferably 7 cm. The thickness from the top surface of each block-shaped protrusion 3 to the surface of the sphere 1 falls within the range of 2 mm to 4 mm. As a result, the ratio of the diameter of the sphere 1 to the thickness from the top surface of each block-shaped protrusion 3 to the surface of the sphere 1 is between 17.5:1 and 35:1, which effectively increases the air resistance when the sphere 1 is thrown.

[0030] The sphere 1 in this embodiment may be a light-transmitting sphere. Furthermore, the sphere 1 may be made of elastic plastic, preferably made of polypropylene (PP) material or polyethylene (PE) material. In this way, it is elastic and has a certain degree of hardness. Furthermore, the inner surface of the sphere 1 may be provided with a uniformly distributed light guide powder. This makes the light transmitted through the sphere 1 softer and more uniformly spread.

[0031] The ridges 2 and the block-shaped protrusions 3 thereon may be made of elastic rubber, and are preferably made of thermoplastic rubber (TPR) material, so that the ridges 2 and the block-shaped protrusions 3 thereon have high resilience and excellent anti-slip properties, making them easy for users to grip and throw.

[0032] Furthermore, the sphere 1 and the plurality of block-shaped protrusions 3 may be molded from a foam material.

[0033] [Second Example] 4 to 6 show a second embodiment of the present invention. This embodiment provides a spherical structure Z2 with a protrusion pattern. This embodiment is similar to the first embodiment, but the differences are described below.

[0034] In this embodiment, a groove 36 is formed on the outer side of any two opposing block-shaped protrusions 3. By providing each block-shaped protrusion 3 with the groove 36, the frictional resistance between the block-shaped protrusions 3 and the air is further increased, and the range of change in the flight path of a curveball can be increased.

[0035] Furthermore, the groove 36 of each block-shaped protrusion 3 may be an elongated groove recessed from the fourth side wall 34 toward the top wall 30 of each block-shaped protrusion 3. This further increases the frictional resistance between the top side and outside of each block-shaped protrusion 3 and the air, allowing the range of change in the flight path of a curveball to be greater.

[0036] [Third Example] 7 shows a third embodiment of the present invention, which provides a spherical structure Z3 with protrusion patterns. This embodiment is similar to the first embodiment, with the differences being described below.

[0037] In this embodiment, the inside of the sphere 1 is hollow, and a counterweight 6 is suspended inside the sphere 1. The suspended counterweight 6 further changes the flight path of the sphere 1. The counterweight 6 is suspended inside the sphere 1 via a connector so as to be located at the center of the inside of the sphere 1, for example, but is not limited to this.

[0038] Furthermore, the counterweight 6 in this embodiment may include an upper counterweight block 61 and a lower counterweight block 62 stacked vertically, and the weight of the lower counterweight block 62 may be greater than the weight of the upper counterweight block 61. This changes the center of gravity of the sphere 1. The counterweight 6 is suspended inside the sphere 1 by being connected to the opposing upper and lower ends of the interior of the sphere 1 via the opposing upper connector 7 and lower connector 8. The upper connector 7 and the lower connector 8 may both be ropes, preferably steel ropes, but may also be elastic ropes, but are not limited thereto. An upper connector 11 is provided at the upper end inside the sphere 1, and a lower connector 12 is provided at the lower end inside the sphere 1. The upper connector 11 and the lower connector 12 may both be connection grooves, but are not limited thereto. The lower end of the upper connector 7 is connected to the upper end of the counterweight 6, and the upper end of the upper connector 7 is connected to the upper connector 11. The upper end of the lower connector 8 is connected to the lower end of the counterweight 6, and the lower end of the lower connector 8 is connected to the lower connection part 12. Furthermore, an upper connector 71 may be provided at the upper end of the upper connector 7, and a lower connector 81 may be provided at the lower end of the lower connector 8. Both the upper connector 71 and the lower connector 81 may be steel balls or steel ingots, but are not limited thereto.

[0039] [Fourth Example] 8 shows the fourth embodiment of the present invention. This embodiment provides a spherical structure Z4 with protrusion patterns. This embodiment is similar to the first and third embodiments, but the differences are described below.

[0040] In this embodiment, the inside of the sphere 1 is hollow, and a counterweight 6 is suspended inside the sphere 1. The suspended counterweight 6 changes the flight path of the sphere 1. The counterweight 6 is suspended inside the sphere 1 via a connector so as to be located at the center of the sphere 1, for example, but is not limited to this. The counterweight 6 is suspended inside the sphere 1 by being connected to the opposing upper and lower ends of the inside of the sphere 1 via opposing upper and lower connectors 7 and 8, respectively.

[0041] Furthermore, the counterweight 6 in this embodiment may be a counterweight circuit board 6a. The counterweight circuit board 6a has a plurality of elements arranged on one side of the circuit board, and the entire weight may be arranged on one side of the circuit board. The counterweight circuit board 6a is provided with a light-emitting unit 61a, a power supply unit 62a, and a main control unit 63a, and the main control unit 63a is electrically connected to the light-emitting unit 61a and the power supply unit 62a. The main control unit 63a may include a single or multiple microprocessors (MCUs) and may be arranged on the front or back side of the counterweight circuit board 6a. The light-emitting unit 61a may include a single or multiple light-emitting diodes 611, and at least two light-emitting diodes 611 are arranged back to back in the light-emitting unit 61a, so that these light-emitting diodes 611 can simultaneously emit light in opposite directions. The power supply unit 62a may include a single or multiple batteries and may be arranged on the front or back side of the counterweight circuit board 6a. In this embodiment, the counterweight circuit board 6a is further provided with a vibration switch 64a electrically connected to the main control unit 63a. The vibration switch 64a may be disposed on the front or rear surface of the counterweight circuit board 6a. The vibration switch 64a detects vibration, and when vibration is detected, the switch is turned on to control each of the light-emitting diodes 611 to be lit, and when no vibration is detected after a preset time has elapsed, the switch is turned off to control each of the light-emitting diodes 611 to be turned off. This extends the service life of the battery. The main control unit 63a may have a standby power mode, so that even if one light-emitting diode 611 fails, the other light-emitting diodes 611 continue to be lit.

[0042] In light of the above, the spherical structure with a protrusion pattern provided in the embodiments of the present invention uses at least the technical means of a "sphere" and "multiple block-shaped protrusions formed in a serpentine pattern in pairs facing each other on the surface of the sphere," allowing even beginners in baseball to easily throw a curveball and further increasing the range of variation in the flight path of the curveball.
