Description

Light-emitting billiard ball{LIGHT EMITTING BILLIARD BALL}

The present invention relates to a billiard ball that emits light when clouds and contact are detected.

In general, a billiard ball is a ball used to play billiards. It was initially made by cutting ivory, but now it is made of thermosetting resin as a material. The billiard ball is 2~2⅜ inches in diameter, has a perfect sphere and symmetry, and requires adequate weight and hardness. Currently, the billiard balls of Saluk, Belgium, sold under the brand Aramis, occupy more than 80% of the world billiard ball market. Among the billiard balls, there are billiard balls in which one or two or more circular marks made of yellow or red dots are formed on the surface, and the marks serve to visually indicate whether the billiard ball rotates, speed, and direction of rotation. In order to form such a mark, it was conventionally manufactured by printing a mark on the surface of a billiard ball. However, there is a problem in that it may be difficult to identify a billiard ball in a dark environment, and it is difficult to determine whether a billiard ball is touched when a sharp grazing occurs between the billiard balls.

Hereinafter, a specific embodiment of the present invention will be described with reference to the drawings. However, this is only an example and the present invention is not limited thereto.

In describing the present invention, when it is determined that a detailed description of known technologies related to the present invention may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of users or operators. Therefore, the definition should be made based on the contents throughout the present specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are only one means for efficiently describing the technical idea of the present invention to those of ordinary skill in the art.

1 is a cross-sectional view of a billiard ball 1 according to an embodiment of the present invention.

Referring to FIG. 1, the billiard ball 1 may include a body 100, a sensor 200, an LED lamp 300, and a battery 400. Specifically, the body 100 may be made of a material including synthetic resin. The body 100 has a spherical shape, and the distance from the centrifugal to the surface may be the same in all directions. In addition, the body 100 may be formed of a material including colored and transparent colored synthetic resins. For example, it may be formed in a red color, but at least a portion may be formed in a transparent color. The portion formed in a transparent color may be the transmissive portion 101. The transmitting part 101 may be a transparent color through which light can be transmitted. That is, the light emitted by the LED lamp 300 through the transmission part 101 may be radiated to the outside of the body 100.

Meanwhile, the transmission part 101 may be formed in a linear shape along the surface of the body 100 in a linear shape as in this example, but may also be formed in a point shape. For example, when a plurality of LED lamps 300 are disposed at predetermined positions in the body 100, respectively, the linear transmission unit 101 or each LED lamp connecting the LED lamps 300 along the surface of the body 100 A point-shaped transmissive portion 101 formed only in a portion corresponding to 300 may be provided.

Meanwhile, the “inside the body 100” refers to an inner space excluding the surface of the spherical body 100. That is, the LED lamp 300 may be located in a form buried in the body 100. When the LED lamp 300 is directly exposed to the outside, an external force such as a collision may be directly transmitted, and the LED lamp 300 vulnerable to the external force may be damaged. Accordingly, the LED lamp 300 is located in the body 100, but may be buried in a synthetic resin forming the transmission portion 101.

A plurality of LED lamps 300 may be provided, and each may be connected to a battery 400 that electrically supplies power. The battery 400 may also be located in the body 100 and be buried. The charging port may be provided to be exposed on the surface of the body 100 so that the battery 400 may be charged, or a method capable of wireless charging may be employed. For example, a cable capable of supplying power by adopting a charging method of a smartphone is provided on one side, and a contact portion (for example, a compound hole) capable of receiving the power through contact (coupling) with the cable is provided. It may be provided on the side of the billiard ball (1). In addition, when a wireless charging method is employed in addition to the wired charging method, a separate transmitting unit for transmitting power is provided, and a receiving unit capable of receiving the electric power when located within a predetermined distance from the transmitting unit is a billiard ball (1). It is located in the billiard ball 1 is placed adjacent to the transmission unit except in use, the power of the billiard ball (1) can be charged.

On the other hand, the sensor 200 is a cloud of the approach sensor 210 and the billiard ball 1 for detecting a collision or contact (may include a case that rotates in place, at least includes a cloud that the billiard ball rolls to move) It may include one or more of the rotation sensor 220 for sensing. The sensor 200 may detect the movement of the billiard ball 1 and the like to emit light from the billiard ball 1. For example, the rotation sensor 220 may detect a cloud when the billiard ball 1 rolls on the billiard table so that the LED lamp 300 emits light. That is, while the billiard ball 1 is rolled and moved, the LED lamp 300 emits light. In addition, the proximity sensor 210 may cause the LED lamp 300 to emit light when the surface of the billiard ball 1 contacts or collides with another object (eg, another billiard ball 1). Here, the “other object” may be a collision ball (10 in FIG. 3) that may collide with the billiard ball 1 moved by the user. In the case of such an approach sensor 210, the detection area of the sensor 200 may be prepared according to a predetermined criterion. Details related to this will be described later in detail with reference to FIG. 3.

2 is a view showing the distance between the entire length located inside the billiard ball (1) according to an embodiment of the present invention.

Referring to FIG. 2, components such as the battery 400, the LED lamp 300, and the sensor 200 described above may be buried and positioned in the body 100. Of course, although not shown, a control unit that is electrically connected to the sensor 200, the LED lamp 300, and the battery 400 to control the light emission of the billiard ball 1 according to a predetermined criterion is also located in the body 100. May be.

As such, various configurations may be located in the body 100. At this time, each component is not concentrated on one side based on the centrifuge of the billiard ball (1), and may be spaced apart from the centrifuge at a predetermined distance, respectively. For example, when components such as the battery 400, the LED lamp 300, the controller (not shown) and the sensor 200 are intensively arranged on one side, the billiard ball 1, which is mostly synthetic resin constituting the body 100 The center of gravity of) may be separated from the distal end to one side or the other side opposite to one side. Since the center of gravity is separated from the centrifuge, it means that the clouds are not uniformly formed, which is not desirable for the design of the billiard ball (1).

Therefore, preferably, when the composition in which the difference in specific gravity is formed with the synthetic resin is concentrated on one side, the center of gravity may be located from the centrifuge to the one side or the other side opposite to one side with respect to the centrifuge. In order to maintain a balanced cloud of the billiard ball (1), the centrifugal and spaced distance of the billiard ball (1) can be determined according to the weight of the configuration to be arranged. For example, when the weight ratio of the battery 400 and the rotation sensor 220 located inside the body 100 is 2:1, the distance between the center of gravity and the centrifugal distance of the battery 400 is a first distance (D1), rotation The distance between the center of gravity of the sensor 220 and the centrifugal distance may be a second distance D2, and a length ratio of the first distance D1 and the second distance D2 may be 1:2. However, the centrifuge is positioned on a line connecting the center of gravity of each of the battery 400 and the rotation sensor 220. The positions of components located inside the body 100 may be determined by the ratio of the separation distance, and accordingly, when the billiard ball 1 rolls on the billiard table, the billiard ball 1 has a uniform rolling (rotation) speed. You can roll into it.

The above example is an example showing that two configurations (battery 400 and rotation sensor 220) are disposed in the body 100, and even when more configurations are disposed, the center of gravity of the billiard ball 1 is the billiard ball (1) It can be a balanced arrangement of each component so that it is located in the centrifugal position.

3 is a view showing an area in which a billiard ball 1 according to an embodiment of the present invention can detect a contact with a collision ball 10.

In general, the billiard ball (1) is used with a plurality of collision balls (10) colliding with the billiard ball (1) on a billiard table. Therefore, hereinafter, a method of sensing the approach sensor 210 will be described by taking the relationship between the billiard ball 1 and the collision ball 10 as an example.

Referring to FIG. 3, the billiard ball 1 may come into contact with the collision ball 10. If the billiard ball (1) collides with the collision ball (10) relatively clearly, the identification of the collision can be easily identified with the naked eye, but if a rubbing level of contact occurs, it may be difficult to distinguish the contact with the naked eye. . Therefore, the approach sensor 210 buried in the billiard ball 1 may be a reaction based on a detection result when a detection object is detected within a predetermined detection area.

The sensing region is formed in both the billiard ball 1 and the collision ball 10, and the sizes of the regions may be different from each other. Hereinafter, a case in which the sensing area of the billiard ball 1 is formed larger will be described as an example. The sensing region may be formed by a predetermined distance from the distal end of the billiard ball 1 toward the surface of the billiard ball 1 in the forward direction. That is, the sensing region may be formed in a spherical shape.

When the sensing region formed in the billiard ball 1 according to an embodiment of the present invention is referred to as the first sensing region A1, the radius of the first sensing region A1 may be greater than or equal to the radius of the billiard ball 1 . For example, when the radius of the first sensing area A1 exceeds the radius of the billiard ball 1, the excess length may be 0.1 mm or less (ie, several micrometers or tens of micrometers). Meanwhile, the radius of the second detection area A2, which is a detection area formed in the impact hole 10, may be formed to be less than or equal to the radius of the impact hole 10.

Although the radius of the first sensing region A1 and the second sensing region A2 is not defined, the billiard ball 1 may be provided to emit light by overlapping the sensing regions. Therefore, when contact occurs between the billiard ball 1 and the collision ball 10, the first sensing region A1 and the second sensing region A1 and the second sensing region A2 overlap each other so that the first sensing region A1 and the second sensing region A2 are overlapped. The sum of the radii of the area A2 may be greater than or equal to the sum of the radii of the billiard ball 1 and the impact ball 10. In addition, forming the sensing region may be one or more of various sensing means such as magnetic force, capacitance, and a predetermined frequency.

That is, the following equation is satisfied, but S may be 0 or more and several micrometers or less (eg, 5 micrometers or less).

B1 + B2 + S ≥ A1 + A2 and A1 ≠ A2

(B1: radius of billiard ball (1), B2: radius of collision ball (10), S: overlapping distance, A1: radius of the first detection area, A2: radius of the second detection area, but S is several micrometers Below)

The configuration of the approach sensor 210 is provided to induce the light emission of the LED lamp 300 when a collision between the billiard ball 1 and the collision ball 10, but according to this example, it does not induce light emission by detecting the collision itself. Does not. Unlike the present embodiment described above, when the billiard ball 1 is emitted by detecting the collision itself, the billiard ball 1 is emitted when it collides with a surrounding structure (for example, a cushion of a billiard table). It may be difficult to identify whether there is contact between the billiard ball (1) and the collision ball (10). Here, the collision means a contact, and the contact includes a case where an overlap distance S occurs and a point contact occurs between the billiard ball 1 and the collision ball 10.

In a general case, since one billiard ball 1 and a plurality of collision balls 10 collide on one billiard table, the structure of the billiard ball 1 according to an embodiment of the present invention to facilitate identification May also be employed for the collision sphere 10, but it is assumed that the sensing region (the second sensing region A2) applied to the collision sphere 10 does not exceed the radius of the collision sphere 10. This is because it may be difficult to identify whether or not contact with the billiard ball 1 is caused when light is emitted by collision between the colliding balls 10. Of course, it is not limited thereto, and the structure of the billiard ball 1 described above may be selectively employed.

Meanwhile, in light emission, at least one of the blinking period and the color of the light may be different from when the rotation sensor 220 detects and emits light, and the approach sensor 210 detects and emits light. The light emission time may be several seconds, for example, may blink for 10 seconds to 15 seconds. In addition, as for the light emission type, a case of collision may be prioritized than a case of rotation. That is, when the proximity sensor 210 detects a touch even while being detected by the rotation sensor 220 and emitting light, the light emitting information (blinking period and color of the light) emitted by the proximity sensor 210 first emits light. Can be.

Of course, this is an example related to the luminescence information, and specific details such as luminescence retention time, luminescence color, and flicker pattern may be selectively determined to form various examples.

Although the exemplary embodiments of the present invention have been described in detail above, those of ordinary skill in the art to which the present invention pertains will understand that various modifications can be made to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention is limited to the described embodiments and should not be determined, and should not be determined by the claims to be described later, but also by those equivalents to the claims.
