Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a laser pointer for indicating an incident path and a reflection path of a billiard ball,

The present invention relates to a laser pointer for indicating an incident path and a reflection path of a billiard ball, and more particularly, to a billing system for a billiard ball which is positioned at a point of a rail striking a cushion of a billiard table when calculating an incident angle and a reflection angle, Which is a first path of the cigarette to the cushion, and a reflection path, which is a second path of the cigarette, which is reflected by the cushion, and which is provided at the end of the first and second pointers, .

In billiard games such as 3 and 4 holes as well as pocket balls, various techniques such as stroke, posture, and force control are required to send the ball to the ball, but it is more important to calculate the angle of the ball.

The reflection angle is the angle at which the cushion attached to the inner side of the rail based on the rail extension direction of the billiard table is the incident angle and the repulsive angle. In particular, the three angle cushion-based three-ball billiard game can not grasp the incident angle and the reflection angle In the case of snowballs or hitting the sand dune with guesswork, the water balloon can not strike the target ball.

In the known method, the hub and five system was often used to calculate the angle of the ball in the ball. This half-and-five system displays the number of cushions, the number of first cushions and the number of third cushions on the rail (or another figure) with a certain distance, such as 10, 20, 30 .., And the like.

However, since the actual billiard table does not display this value, it is necessary to memorize all the positions of the numerical value. However, if the user does not have a considerable ability, it is difficult to accurately measure the point at which the numerical value is recorded. .

  Korean Patent No. 1795670 discloses that a billiard practice device has a laser pointer for a watercraft indicating a watercourse and a laser pointer for an object pointing to an objective point on one side of a rail to help calculate a billiard angle. It is not possible to know the incidence angle and the reflection angle of the water pellet by referring to the target pellet and the target pellet. Therefore, in this structure, the user can not greatly assist in predicting the reflection angle of the water pellet with the naked eye, Which is not only inconvenient to operate but also difficult to use as a whole.

The laser point for billiard is provided with a plurality of points at regular intervals along the rails of the billiard table, and the laser beam irradiated at the point is visually checked, According to this technique, the point is installed unnecessarily so that the complicated laser beam interferes with the billiard game, and the point is fixed at a certain point on the rail. There is a problem that it is difficult to easily change the position.

Therefore, the present invention can be embodied as a single device capable of easily adjusting the incident angle and reflection angle of the cue ball, that is, the laser outputting means for indicating the incident path and the reflection path, according to the user's skill and can freely move in the billiard- There is a need to develop a laser pointer for a billiard game.

SUMMARY OF THE INVENTION The present invention has been made to overcome the problems of the prior art, and it is an object of the present invention to provide a laser output unit for directing an incident path and a reflection path by a reflection angle, And to provide a laser pointer which can be freely moved and utilized.

Another object of the present invention is to realize two laser output units such as a compass rotatable around a hinge.

It is still another object of the present invention to provide a means for visually displaying an incidence path of a watercraft and an angle corresponding to a reflecting path.

It is a further object of the present invention to provide a means for announcing the anticipated reflected path for each of our locations through the big data that has learned the reflection path that changes for each point of the watercourse at a specific incident angle.

It is a further object of the present invention to provide a means for storing chokes in a device that integrally displays an incident path and a reflected path.

In order to achieve the above object, a laser pointer for indicating an incident path and a reflection path of a billiard ball according to the present invention includes a first and a second pointer having a laser output unit for outputting a laser beam at an end, ; And a hinge that is mounted on a joint portion on an opposite side of the first and second pointers mounted with the laser output unit and rotates the first and second pointers in an angle-adjustable manner.

The laser pointer may be inserted into the through hole so that an angle mark is formed along a rotating direction of the second pointer. The laser pointer is inserted into the through hole at a position spaced apart from the junction of the first and second pointers by a predetermined distance, And an angle display guide rounded according to a rotation locus of the second pointer.

The joining portion of the first pointer surrounds the hinge and is mounted on the joining portion of the first pointer in a cylindrical shape so as to be rotatable around the hinge. The joining portion includes a reference mark formed at a position facing the outer periphery of the hinge, An angle grasp unit for grasping an angle of incidence which is an angle between the virtual line and the first pointer toward the water hole in a state where the imaginary line connecting the reference mark is parallel to the rail of the billiard table; A guide portion for guiding the laser beam; a display portion for visually outputting the shape and shape of the watercourse and the position of the watercourse; While displaying our shop location on the display unit, we display our shop displayed on the display unit It characterized by further comprising a; the estimated route guides made of a reflection path of the guide laser power output control unit for driving selection unit located in the predicted path identified in the identifying unit.

According to the laser pointer indicating the incident path and the reflection path of the billiard ball according to the present invention,

1) By directly controlling the expected path of the watercourse by laser, it is possible to visually confirm the expected path of the watercourse directly and intuitively according to the user's ability,

FIG. 1 is a front view showing a schematic structure of a laser pointer of the present invention, and FIG. 2 is a state in which a laser pointer of the present invention is placed on a rail of a billiard table.

1, the laser pointer of the present invention includes two pointers, namely, first and second pointers 10 and 20, which are rotated in an angle-adjustable manner via a hinge 30 in a state of being extended by a predetermined length And a laser output unit 40 mounted on the end of each of the first and second pointers 10 and 20.

Specifically, the first and second pointers 10 and 20 have a structure that can be recognized as a specific direction when viewed from the naked eye, and can take a rod shape, for example. In the rod shape, it may be formed into a cylindrical shape like a rod, or a polyhedron such as an angled shape like a hexahedron shape.

The first and second pointers 10 and 20 are provided at the ends thereof with a laser output unit 40. The laser output unit 40 serves to generate laser light. In summary, one end (junction) of the first and second pointers 10 and 20 is connected to the hinge 30 and the other end has a laser output unit 40.

The principle of generating laser light in the laser output unit 40 is a semiconductor laser system that generates laser light using a semiconductor device and a medium pumping system that pumps the medium to external light energy. Laser light is generated by using a device, and generated light spreads like an LED widely. Therefore, laser light is generated by collecting the generated light into a small point through a lens (for example, a condenser lens or a collimator lens).

The laser output unit 40 of the present invention preferably includes the above-described semiconductor laser light emitting structure. Such a semiconductor laser light emitting structure includes a laser diode, a driving circuit, and a light collecting unit. . The laser output unit 40 may be operated by a switch provided on one side of the first and second pointers 10 and 20, and further, the laser pointer of the present invention may be interlocked with the user's smartphone The switch may be turned on / off by the remote control of the smartphone.

The hinge 30 is formed in the joint portion 50 of the first and second pointers 10 and 20 so that the first and second pointers 10 and 20 can be rotated about the hinge 30. Although the hinge 30 may have various structures, the hinge 30 of the present invention is based on a pin-shaped hinge shaft to which the joint portions 50 of the first and second pointers 10 and 20 are coupled .

In order to prevent unnecessary rotation of the first and second pointers 10.20 with respect to the hinge 30, a friction member may be wrapped around the hinge 30. Such a friction member may include polyacetal, MC Such as nylon, polyurethane, polyisoprene, polybutadiene rubber, polyacrylate rubber, polyether rubber and the like, so that the user can intentionally open or close the first and second pointers 10 and 20 The first and second pointers 10 and 20 can be rotated.

 The coupling structure of the hinge 30 and the first and second pointers 10 and 20 takes the same structure as a compass for drawing. For example, the first and second pointers 10 and 20 may be formed in the shape of 'g' or 'a' around the hinge 30.

As described above, the hinge 30 can be constructed in such a structure that it is coupled with the first and second pointers 10 and 20 only by a pin-shaped hinge axis. However, the first and second pointers 10 and 20, 20 may be formed in a flat plate shape surrounding the hinge axis so that a certain volume can be secured in the vicinity of the hinge. In order to ensure the operation of the hinge shaft, the hinge shaft and the first and second pointers A cover for covering the joint portion 50 may be additionally provided.

Hereinafter, the operation of the laser pointer of the present invention will be described in detail with reference to FIG.

As shown in FIG. 2, when a ball and a ball are placed on a billiard table based on a four-ball pool game, the user must hit the ball first through the ball and then use the ball's cushion to send the ball to the second ball . In other words, it is more preferable that the user performs a stroke for hitting the point while looking at one point of the rail of the billiard table to be reflected by the cushion rather than stroking while looking at the first fist, The laser pointer of the present invention is positioned at the corresponding one of the rails of the laser. Of course, the same principle applies to the third ball, at which time the ball can be hit directly at the point of the ball of the pool table without hitting the first ball, that is to say, It is also applicable to striking a specific rail point directly on the billiard table without hitting the target ball.

Then, the first pointer 10 is positioned so as to face the water inlet, and the second pointer 20 is pivoted by the first pointer 10 so as to face the object, and then the first pointer (10) The laser outputted from the laser output unit 40 of the second pointer 20 directs the hand and the laser output from the laser output unit 40 of the second pointer 20 directs the target sphere. At this time, the laser beams output from the first and second pointers 10 and 20 may be of different colors.

In such a principle, it is very important to locate the laser pointer of the present invention at any point on the rail of the pool table according to the user's experience and skill. In other words, in the known pipe-and-half system, there is a considerable limit to reflect the actual situation in which the shop of the watercraft can be moved in various ways depending on the strength of the shop and the stroke of the billiard ball, The laser pointer provides a characteristic that reflects a complex situation such as the shop, the strength of the stroke, and the point of the strike of the rail.

That is, since the user can visually check the expected path of the watercraft, that is, the incident path and the reflection path through the laser pointer of the present invention, the stroke and the watercourse can be struck, It provides traits to adjust the strength of the railway point of our billiard table and the strength of our shop and stroke to check the difference between the route and the actual route that we expected.

3 is a front view showing a state in which an angle indicator is attached to the laser pointer of the present invention.

The pointer of the present invention may have a structure such as that shown in FIG. 3 in which the joint portion 50 and the hinge 30 are structured as shown in FIG. 3. In particular, at a point spaced apart from the joint portion 50 of the first and second pointers 10, And the angle indicator 70 is inserted and extended in the through hole 60 of the first and second pointers 10 and 20, respectively.

The angle indicating guide 70 has a rounded and extended shape corresponding to the locus of the second pointer 20 rotated on the basis of the first pointer 10 and has a hinge 30 The angular mark 71 indicating an angle scale is formed so that the angle increases toward the rotating direction of the second pointer 20 based on the imaginary line toward the second pointer 20. In order to prevent the angular marking guide 70 from being separated from the through hole 60, a thread 72 is provided on both ends of the angle marking guide 70, which is outside the through hole of the first and second pointers 10 and 20 And a fastener such as a nut N can be coupled to this thread. 3 shows that the threads are formed on only one side of the angle marking guide 70. However, in order to prevent the deviation of the angle marking guide 70 from the engagement of the nut N on the right and left sides, desirable.

According to the angle marking guide 70, when the user rotates the second pointer 20 to open the first pointer 10 in a fixed state, So that it is possible to intuitively provide the user with a guide to angle display of a different concept than the known five-half system.

FIG. 4 is an exploded perspective view showing a state in which a predicted path guide is mounted on the laser pointer of the present invention, FIG. 5 is a conceptual view showing a state in which a predicted path is displayed by laser while displaying our position in the predicted path guide of FIG. to be.

The present invention is not limited to a function of displaying a path of a handwriting projected by a user directly by a laser, but it is also possible to use a laser pointer of the present invention placed on a rail and a path reflected from a cushion (Hereinafter referred to as a "predicted path") through a laser of a separate laser output unit 40. In order to clearly understand the expected path of the watercourse, it is assumed that the watercourse predicts the expected path of the watercourse on the assumption that the watercourse strikes the ball on the billiard table directly without hitting the first object.

The predicted path guide 100 of the present invention for providing the above functions includes a reference mark 101, an angle grasping unit 110, a predicted path grasping unit 120, a guide laser output unit 130, a display unit 140 And an output control unit 150. [

First, the shape and mounting position of the predicted path guide 100 will be described. The hinge 30 is mounted on the upper surface of one of the first and second pointers provided around the hinge 30 so as to be rotatable around the hinge 30 .

More precisely, the predicted path guide 100 is mounted on the joint 50 of the first pointer 10, in which case the joint 50 of the first pointer 10 is placed in the expected path < RTI ID = The top surface of the guide 100 may have a flat surface so as to ensure stable rotatability of the expected path guide 100. In addition,

4, a cylindrical guide hinge 80 having a hollow portion is protruded from the joint portion 50 of the first pointer 10 at the periphery of the hinge 30, And a mounting groove having a diameter corresponding to the diameter of the guide hinge 80 is formed in the bottom surface thereof. Thus, through the engagement between the guide hinge 80 and the mounting groove, the predicted path guide 100 is rotatably mounted on the joint portion 50 of the first pointer 10 around the hinge 30, A stopper may be formed at the joint portion of the guide hinge 80 or the mounting groove. The reason why the guide hinge 80 protrudes in a cylindrical shape having a hollow is to prevent a problem that unnecessary contact is made in the hinge 30 to hinder the rotation operation of the hinge 30. [

A reference mark 101 is printed on the outer circumferential surface of the anticipated path guide 100 having such a structure at positions facing each other (that is, at an angle of 180 degrees).

The reference mark 101 is used to set a reference for grasping the angle of the cue ball with the laser pointer of the present invention. The user rotates the predicted path guide 100 so that the reference marker 101 coincides with the rail extension direction of the billiard table . In other words, the virtual line connecting the two reference marks 101 can be recognized as an extension line of the pool table rail.

The angle detecting unit 110 detects the position of the ball catcher 110 at a position where the laser pointer of the present invention is positioned on the rail with reference to the extending direction of the billiard table rail through the virtual line connecting the reference marker 101 and the extending direction of the first pointer 10. [ And an angle (referred to as " incident angle " in the present invention).

For example, a reference terminal is formed at a position corresponding to a position where the reference mark 101 is indicated in the mounting groove, and the guide hinge 80 A plurality of contact terminals are provided at predetermined intervals along the circumference of the contact surface, and the contact terminals have unique position information. Thus, the angle between the virtual line indicated by the first pointer 10 and the virtual line connecting the reference mark 101 can be grasped by a method of grasping the position value of the contact terminal in contact with the reference terminal among the contact terminals. Of course, the angle detecting unit 110 may include various position / angle detecting means in addition to the contact terminal identifying method to detect an angle, that is, an incident angle, between the handpiece and the laser pointer of the present invention.

The predicted path determination unit 120 performs a function of grasping a path, that is, a reflection path, after the ball has hit the pool table cushion for each point of the ball through the shop database 121 based on the detected incident angle.

Here, the database 121 of our shop is a kind of look-up table (hereinafter referred to as " look-up table ") in which a path through which a water- ).

In general, our shop is divided into three points in the oblique direction as well as up, down, left and right based on the center, so there is a variety of shops in the same one, so the path is reflected by our position even if the same force is applied It really varies.

In other words, the database 121 of the present invention can be understood as a database in which the reflection path of the watercourse changes according to the position of the user when a predetermined equal force is applied at a specific incident angle.

The guide laser output unit 130 is formed with a plurality of laser output units at regular intervals (angles) along the circumference at any one of upper and lower points of the position where the reference mark 101 is formed, The laser output units 130 may be disposed at a plurality of angles with an angle of 5 to 15 degrees. Based on the number of the laser output units 130, a basis for providing a more detailed estimated path may be provided. In addition, each of the guide laser output units 130 can hold unique position information, and can provide a basis for selecting a guide laser output unit 130 at a specific position in an output control unit 150 .

The display unit 140 is mounted on the upper side or the upper side of the predicted path guide 100 so as to face the one side of the predicted path guide 100, specifically, the direction of the first pointer 10 at which the user is located. Perform the function of displaying the shape of the water polo together with our shop. At this time, the display unit 140 can be mounted on the upper surface of the predicted path guide 100 so as to be rotated, folded or pulled in.

 The output control unit 150 displays the specific point position for a predetermined time, for example, about 1 to 5 seconds on the display unit 140, and simultaneously outputs the guide laser output unit 130 corresponding to the expected path at the corresponding point The process of outputting the laser to the selected guide laser output unit 130 for a predetermined time is repeated. That is, the display unit 140 sequentially displays the position of the shop, And output through the output unit 130.

This allows the user to determine whether the expected path of the watercourse is correct at his / her thought position when hitting the watercourse, and if it is not correct, quickly fix the location of the watercraft to hit the watercourse or move the laser pointer of the present invention to another rail point When moving to another rail point, as mentioned above, the expected route for each of our locations can be checked again by laser, so that it is possible to train the position of rail as well as our shop position.

5, the predicted path guide 100 does not include the display unit itself, but interlocks with the smartphone S of the user and visually displays the shop location of the water supply through the smartphone S It is possible.

Specifically, the laser pointer of the present invention may further include a signal processing unit in a state in which the predicted path guide 100 is equipped with a local communication means such as Bluetooth to interoperate with the smartphone S. The signal processing unit receives a signal from the smartphone S through the short-range communication unit and transmits the signal to the predicted path guide. Such an interlocking relationship is configured and functioned by the known wireless communication signal processing unit Because they are similar, a separate explanation is omitted.

In response to this, the display unit D displays the shape of the cue ball and the shop of the cue ball through the mobile application installed in the smart phone S owned by the user, and the predicted path at the corresponding shop is outputted to the guide laser output unit 130 ). ≪ / RTI >

Further, when the user presses a specific position of the watercraft on the touch screen when the watercourse is output from the display part D of the smartphone S composed of the touch screen, the smartphone S recognizes it as a shop and generates an identification signal And transmits it to the signal processing unit. Thereafter, the signal processing unit transmits the received identification signal to the estimated path determination unit 120, and the estimated path determination unit 120 calculates the expected path of the water balloon at the corresponding point have.

In addition, when the user presses a specific shop location of the water dispenser output through the display unit D of the smartphone S, the predicted route guide 100 recognizes the shop location, The user can select the guide laser output unit 130 corresponding to the path and output the laser, thereby providing the user with the ability to promptly inform the user of the anticipated path at the shop location, which the user particularly wonders.

In addition, referring to FIG. 4, it is possible to provide the water hole distance measuring unit 160 around the laser output unit 40 of the first pointer 10.

The cue distance measuring unit 160 provides a function of measuring the distance between the laser pointer and the cue ball of the present invention and may include various distance measuring means. For example, when the mouth distance measuring unit 160 is configured as an ultrasonic measuring unit, the function of receiving ultrasonic waves to the mouth and detecting the distance from the first pointer 10 to the mouth is performed.

According to the above description and function, even if the angle between the cradle and the rail is grasped, the variable of the distance from the angle to the cradle can not be properly reflected, but in the present invention, the cradle distance measuring unit 160 is additionally provided So that the user can know the distance between the ballpoint pen and the laser pointer of the present invention or the distance between the pool ball rail, thereby providing a basis for controlling the stroke.

In response to this, the display unit 140 visually displays the distance detected by the water hole distance measuring unit 160, and the estimated path determining unit 120 sets the intermediate distance considering the long side and the short side of the billiard table as the reference distance The distance measuring unit 160 compares the distance measured by the distance measuring unit 160 with a reference distance and performs a function of adding and reflecting the weight to the estimated path according to the difference of the difference. It goes without saying that our database 121 can also supplement the functions of the estimated route determination unit 120 by further providing the expected route identification data for each of the shops according to the distance between the specific points of view.

In summary, the characteristics such that the predicted path can be grasped more accurately and more accurately is provided through the cue meter distance measuring unit 160.

FIG. 6 is a perspective view showing a modified embodiment of the predicted path guide of FIG. 4; FIG.

The embodiment of FIG. 6 provides a structure in which the choke storage part 170 is formed on the upper surface of the predicted path guide 100. Although not shown in the drawing, the choke storage unit 170 can be applied to the case where the predicted path guide 100 is not provided. Specifically, the joint portion 50 of the first pointer 10 is connected to the hinge 30, The first pointer 10 may be formed at a point outside the hinge 30 on the joint 50 of the first pointer 10.
