The following embodiments will further explain the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention. In addition, the term "or" used herein may include any one or more combinations of the associated listed items depending on the actual situation.
[0030] Example 1
[0031] See also Figures 1 to 3 As shown in FIG. , which is Embodiment 1 of the present invention, this embodiment provides a spherical structure Z1 with raised patterns. The spherical structure Z1 provided in this embodiment includes a sphere 1 and a plurality of bumps 3, each of which is formed on the surface of the sphere 1 in a zigzag pattern, facing each other. Furthermore, these bumps 3 are used to increase the wind resistance of the sphere 1 when it is thrown, thereby greatly varying the flight path of the change-of-direction ball.
[0032] In this embodiment, a meandering ridge 2 may be formed on the surface of the sphere 1 , and the bumps 3 are formed on the ridge 2 on the surface of the sphere 1 in pairs facing each other to increase wind resistance.
[0033] Furthermore, the ridges 2 and the bumps 3 thereon in this embodiment may correspond to the stitching positions of a baseball. Each bump 3 is irregularly shaped, preferably an irregular pentagon, and any two opposing bumps 3 form a connected narrow air duct 4 and a gradually expanding air duct 5, which disrupts air flow and increases wind resistance.
[0034] Specifically, each lug 3 has a top wall 30 and five side walls connected to the top wall 30. These side walls are arranged 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 connects the second side wall 32 and the fifth side wall 35, the fourth side wall 34 connects the fifth side wall 35 and the third side wall 33, and the second side wall 32 connects the first side wall 31 and the third side wall 33. The inner and outer opposing sides of each lug 3 are the first side wall 31 and the fourth side wall 34, respectively. The surface area of the first side wall 31 is smaller than that of the fourth side wall 34. The aforementioned narrow air duct 4 is formed between any two opposing first side walls 31 of the lugs 3, and the aforementioned gradually diverging air duct 5 is formed between any two opposing second side walls 32 of the lugs 3.
[0035] The diameter of the sphere 1 of this embodiment is preferably 7 cm, and the thickness from the top surface of each bump 3 to the surface of the sphere 1 is controlled between 2-4 mm. The ratio of the diameter of the sphere 1 to the thickness from the top surface of each bump 3 to the surface of the sphere 1 is between 17.5:1 and 35:1, thereby effectively increasing the wind resistance of the sphere 1 when it is thrown.
[0036] In this embodiment, the sphere 1 can be a light-transmitting sphere and can be made of a flexible plastic, preferably polypropylene (PP) or polyethylene (PE), which exhibits elasticity and maintains a certain degree of hardness. Furthermore, the inner surface of the sphere 1 can be evenly distributed with light-guiding powder to soften and evenly distribute the light transmitted therethrough.
[0037] The ridges 2 and the bumps 3 thereon can be made of elastic rubber, preferably thermoplastic rubber (TPR) material, so that the ridges 2 and the bumps 3 thereon can have high resilience and excellent anti-slip properties, which can facilitate the user to grasp and throw.
[0038] In addition, the sphere 1 and the plurality of bumps 3 may also be formed of a foam material.
[0039] Example 2
[0040] See also Figures 4 to 6 As shown, this is the second embodiment of the present invention. This embodiment provides a spherical structure Z2 with raised patterns. This embodiment is substantially the same as the first embodiment, and the differences are described as follows.
[0041] In this embodiment, the outer sides of any two opposing protrusions 3 are further recessed to form a groove 36. The groove 36 further formed on each protrusion 3 increases the frictional resistance between the protrusion 3 and the air, thereby increasing the range of change in the flight path of the deflection ball.
[0042] Furthermore, the groove 36 of each bump 3 is a narrow and long groove, which can be formed by the fourth side wall 34 of each bump 3 being recessed toward the top wall 30. This can better increase the frictional resistance between the top and outer sides of each bump 3 and the air, so that the flight path of the change ball can change more widely.
[0043] Example 3
[0044] See also Figure 7 As shown, this is the third embodiment of the present invention. This embodiment provides a spherical structure Z3 with raised patterns. This embodiment is substantially the same as the first embodiment, and the differences are described as follows.
[0045] In this embodiment, the interior of the sphere 1 is hollow, and a counterweight 6 is suspended inside the sphere 1 to further change the flight trajectory of the sphere 1 through the suspended counterweight 6. The counterweight 6 can be suspended inside the sphere 1 by a connecting member, for example, at the center of the sphere 1, but is not limited thereto.
[0046] Furthermore, the counterweight 6 of this embodiment can include an upper counterweight block 61 and a lower counterweight block 62 stacked up and down, and the weight of the lower counterweight block 62 can be greater than the weight of the upper counterweight block 61, thereby changing the center of gravity of the sphere 1. In addition, the counterweight 6 can be suspended inside the sphere 1 by connecting the upper and lower ends of the sphere 1 relative to each other through an upper connecting member 7 and a lower connecting member 8. The upper connecting member 7 and the lower connecting member 8 can be a rope, preferably a steel rope, but can also be an elastic rope, but are not limited to this. The upper end of the sphere 1 has an upper connecting portion 11, and the lower end of the sphere 1 has a lower connecting portion 12. The upper connecting portion 11 and the lower connecting portion 12 can be a connecting groove, but are not limited to this. The lower end of the upper connecting member 7 is connected to the upper end of the counterweight 6, and the upper end of the upper connecting member 7 is connected to the upper connecting portion 11. The upper end of the lower connecting member 8 is connected to the lower end of the counterweight 6, and the lower end of the lower connecting member 8 is connected to the lower connecting portion 12. In addition, the upper end of the upper connecting member 7 may have an upper connecting body 71, and the lower end of the lower connecting member 8 may have a lower connecting body 81. The upper connecting body 71 and the lower connecting body 81 can each be a steel ball or a steel block, but are not limited thereto.
[0047] Example 4
[0048] See also Figure 8As shown, this is the fourth embodiment of the present invention. This embodiment provides a spherical structure Z4 with raised patterns. This embodiment is substantially the same as the first and third embodiments, and the differences are described as follows.
[0049] In this embodiment, the interior of the sphere 1 is hollow, and a counterweight 6 is suspended within the sphere 1 to alter the flight trajectory of the sphere 1. The counterweight 6 can be suspended within the sphere 1 by connectors, for example, at the center of the sphere 1, but this is not a limitation. Furthermore, the counterweight 6 can be suspended within the sphere 1 by connecting upper and lower connectors 7 and 8, respectively, to the opposite upper and lower ends of the sphere 1.
[0050] Furthermore, the counterweight 6 of this embodiment can be a counterweight circuit board 6a. The arrangement of the multiple components on the counterweight circuit board 6a can be biased toward one side of the circuit board, so that the overall weight can be biased toward 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 can include a single or multiple microprocessors (MCUs), which can be located on the front or back of the counterweight circuit board 6a. The light-emitting unit 61a can include a single or multiple light-emitting diodes 611, and the light-emitting unit 61a can include at least two light-emitting diodes 611, and the two light-emitting diodes 611 are arranged in opposite directions so that these light-emitting diodes 611 can emit light simultaneously in opposite directions. The power supply unit 62a can include a single or multiple batteries, which can be located on the front or back of the counterweight circuit board 6a. In this embodiment, the counterweight circuit board 6a may also be equipped with a vibration switch 64a electrically connected to the main control unit 63a. The vibration switch 64a may be located on either the front or back of the counterweight circuit board 6a. The vibration switch 64a is configured to sense vibration and, when it detects vibration, turns on each LED 611. If no vibration is detected after a predetermined time, the LEDs 611 are turned off, thereby extending battery life. Furthermore, the main control unit 63a may also include a backup power supply mode, ensuring that if one LED 611 fails, the remaining LEDs 611 remain illuminated.
