Description

Stroke control practice device for billiard cues

The present invention relates to a device for practicing stroke control of a billiard cue, and more particularly, to uniformly control the force so that the billiard cue can perform a constant velocity motion as much as possible without unnecessary acceleration or deceleration during the stroke, which is the basis of accuracy in billiards. It relates to a stroke control practice device of a billiard cue that can be practiced.

Billiards is a game that moves a billiard ball placed on a billiard table by hitting it with a billiard cue according to various game rules. The ability to control the trajectory of the ball is called billiards skill.

The billiard ball responds more sensitively than you think. Even if a force is applied to the same position of the billiard ball, various trajectories appear depending on the degree to which the user pushes the cue and the strength of the pushing force, so it is better to adjust the force applied to the cue. Above all, it is important.

That is, since the stroke mediated by the billiard cue is the basis of the accuracy of billiards, in order to accurately move the billiard ball to a desired point, it is important to control the strength and weakness of the stroke as well as the accuracy of the stroke posture. In particular, it is necessary for excellent billiards skills to apply the same force as the force provided at the time of hitting the billiard ball after hitting it, but it is not easy to actually practice it. It can be said that this difference in stroke skill differentiates professional players from amateurs.

The present applicant has experience in showing various techniques to control the stroke during billiard practice.

Among them, Korean Patent No. 1989282, a billiard cue auxiliary device using an eddy current generation principle, is a rod-shaped conductor having a hollow inside it, and includes a body having an inlet that communicates with the hollow at at least one end; a guide bar that is coupled to the tip of the billiard cue via a coupling part mounted on one end and is inserted into the hollow and is movable along the longitudinal direction of the hollow; Consists of a permanent magnet wrapped and fixed around one side of the guide bar, which is the opposite side of the portion where the coupling part is mounted, and when the guide bar moves in the longitudinal direction of the hollow, the body corresponds to the moving direction of the guide bar. An eddy current is generated to have a magnetic force in the opposite direction, providing a function of controlling the force of one's stroke while feeling the eddy current with the user's hand.

As in the prior art, stroke practice can be performed through an auxiliary device of a billiard cue, but without the aid of a large tool such as a separate billiard cue assistant, a small tool that is relatively easy to manufacture and easy to apply is used uniformly through the billiard cue. There is a need to develop a new billiards practice device capable of cultivating the ability to apply a stable force.

The present invention has been devised to overcome the problems of the above technology, and when hitting a stacked structure of a base block and a floating block placed instead of a billiard ball on a billiard table, a stroke force that does not generate acceleration is stably prevented so that the floating block does not fall due to inertia Its main purpose is to provide a billiard practice device that can be provided as

Another object of the present invention is to adjust the inertia of the flow block by detachably mounting a block capable of applying a separate weight to the base block or the flow block.

Another object of the present invention is to control the inertia of the flow block by treating the friction force of the hitting area where the tip of the billiard cue is hit differently from other parts.

A further object of the present invention is to provide an adhesive layer on the contact surface of the base block and the flow block to compensate for the problem that beginners can easily drop the flow block.

In order to achieve the above object, an apparatus for practicing stroke control of a billiard cue according to the present invention includes a three-dimensional base block having a seating surface and having a striking area hit by the stroke of the billiard cue; As being seated on the seating surface of the base block, a flow block that flows or falls from the base block due to inertia when a stroke is applied to the striking area; characterized in that it includes a.

In addition, the stroke control exercise device, a weight block for imparting a weight; further comprising, the base block and the floating block, characterized in that provided with a coupling portion for detachably coupling the weight block.

In addition, in the hitting area, it is characterized in that the friction imparting layer made of a material different from the friction force of other parts of the base block is laminated.

According to the device for practicing stroke control of billiard cues according to the present invention,

1) The uniformity and stability of the force applied during the stroke can be easily grasped through whether the floating block seated on the base block has fallen, providing an environment for simple and convenient stroke practice.

2) The inertia of the floating block can be conveniently adjusted by adding a weight block to the base block or the floating block.

3) By laminating a sponge or elastic pad in the striking area to treat frictional forces differently, as a result, not only can the inertia of the flow block be easily adjusted,

4) By applying an adhesive layer on the contact surface of the base block and the flow block, it provides the effect of compensating for the loss of motivation for practice by beginner users who drop the flow block too easily.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numbers in each figure refer to like components.

Figure 1 is a perspective view showing a basic embodiment of the stroke control practice apparatus of the present invention, Figure 2 is a perspective view showing a state in which the stroke of the billiard cue hits the hitting area of the base block.

As can be seen from FIGS. 1 and 2 , the exercise device of the present invention consists of a combination of a base block 100 and a flow block 200 seated on the base block 100 .

The base block 100 is a three-dimensional structure placed on the surface (base) of the pool table (or the top surface of the table other than the pool table, etc.) It is possible to take various three-dimensional shapes regardless of a specific shape if the three-dimensional structure is a three-dimensional structure that has a curved bottom surface such as a ball or a ball with the same height or a large size and is not a rolling shape.

The base block 100 basically includes a striking area 110 and a seating surface 120 .

The hitting area 110 refers to an area where the tip of the billiard cue is hit, that is, it may be a region in which the tip of the billiard cue is struck as well as being hit during the stroke of the billiard cue to receive an impact.

Such a striking area 110, for example, assuming that the base block 100 is made of a hexahedron, it can be said that it is common sense to be formed on the side rather than the top or bottom surface of the base block 100, the tip of the billiard cue In order to prevent the tip from sliding unnecessarily in the hitting area when hitting, it is preferable to have a flat surface rather than a curved surface in a state that is larger than the tip of the billiard cue.

Furthermore, in the hitting area 110, when the billiard cue strikes and moves in a state in which the base block 100 is stopped on the surface of the pool table, the inertia easily occurs in the flow block 200 by the static friction force of the base block 100. It is also possible that a thin-film sponge or elastic pad made of an elastic material that can absorb some of the impact during the stroke of the billiard cue in a state that is not too rough or uneven on the surface can be seated so as to reduce the effect even in part.

The seating surface 120 is a surface on which the flow block 200, which will be described later, is seated, and the flow block 200 is not shaken or separated until the tip of the billiard cue hits the base block 100 and the base block 100 is stable. ) to provide the minimum structure and area that can be seated.

For example, when the base block 100 is a hexahedron, the upper surface of the base block 100 may be referred to as the seating surface 120, that is, the area and plane at a level at which the flow block 200 is not easily separated because it is made of a curved surface. It may be defined as the upper surface of the provided base block 100 .

Although the base block 100 exemplifies the shape of a hexahedron in FIGS. 1 and 2, the base block 100 of the present invention is a truncated cone having a flat top, bottom and side surfaces in addition to the hexahedron as mentioned above, It is possible to be made of a polyhedron or the like.

This base block 100 provides a function of stably seating the flow block 200, which will be described later, before the stroke of the billiard cue. To this end, the basic principle is that the base block 100 is not made of a material that is too heavy or lighter than the flow block 200 or has a shape that is unnecessarily flowing or swaying from before the stroke of the billiard cue, that is, it is sufficiently applied to the surface of the billiard table. It is to be provided with the above-described hitting area 110 and the seating surface 120 as well as a flat bottom surface of a material having a surface friction coefficient of a level that does not easily slip when in contact.

The flow block 200 is a three-dimensional structure that is seated on the seating surface 120 of the above-described base block 100. Like the base block 100, a flat bottom surface having an area at a level not to be easily separated from the base block 100, That is, if the seating surface 120 is provided, it is possible to have various three-dimensional shapes such as a hexahedron.

Such a flow block 200 must have the same volume and weight as the base block 100 when only the property of being able to be separated from the seating surface 120 of the base block 100 due to inertia force during the stroke of the billiard cue is secured. there is no That is, in FIGS. 1 and 2 , the base block 100 and the flow block 200 are exemplified as having a similar volume, shape, and material, but the present invention is not limited thereto.

The functions of the base block 100 and the floating block 200 having these characteristics will be described as follows.

First, the base block 100 is positioned instead of the billiard ball on the surface of the billiard table, and then the flow block 200 is seated on the seating surface 120 of the base block 100 in a stacked manner.

In this state, the user hits the hitting area 110 of the base block 100 by applying a stroke to the billiard cue. At this time, the following phenomena may occur depending on the acceleration and the state at the time of hitting.

First, if the user gradually strikes the billiard tip on the hitting area 110 of the base block 100 with the stroke of the billiard cue and then maintains the stroke at the same speed as the hitting speed, acceleration as well as the movement of the base block 100 Since inertia does not occur, the flow block 200 is pushed together with the base block 100 on the surface of the pool table by the tip of the billiard cue in a state in which it is seated without falling from the base block 100 .

Second, when the user hits the hitting area of the base block 100 by applying a stroke to the billiard cue with a strong force, the moment the base block 100 is pushed by the impact and inertia, the flow block 200 is the base block 100 Falls forward or escapes in the opposite direction to the pushing direction.

Third, if the user hits the hitting area of the base block 100 by applying a stroke to the billiard cue at first, that is, gradually, that is, with a small force, and then suddenly increases or decreases the force, the flow block 200 is initially It is pushed by the billiard cue together with the base block 100 without falling, and then falls forward (when the force is increased) or falls backward (when the force is suddenly stopped or reduced) due to inertia.

Inertia acts on the flow block 200 depending on whether an acceleration component is included in the moving speed of the base block 100 and whether a force greater or smaller than the static friction force of the base block 100 is applied as a stroke It is based on the basic natural law of falling forward or backward or remaining in place.

That is, among the above-described examples, the exercise device of the present invention can implement the same phenomenon as the first example (a phenomenon in which the flow block does not fall by maintaining the same force after hitting the striking area gradually), so that the user's stroke force adjustment and hand It provides the main function to practice to learn the sense of

In other words, in order to have excellent billiard skills, it is most important to control the force of the stroke, that is, the force applied at the beginning does not change and remains at the same level until the end. This is because the ability to move the billiard ball to the desired position in various situations can be secured only when the ability to push the ball is equipped.

In other words, the practice device of the present invention is capable of cultivating fine stroke ability and concentration and attention that can be moved together with the base block 100 without the flow block 200 falling to the surface of the pool table as much as possible during the stroke of the billiard cue. It provides a function, in particular, the user can easily check whether the flow block 200 has fallen with the naked eye, thereby providing a characteristic that combines the convenience of improving the sense of the hand while grasping the state of his or her stroke.

Furthermore, referring to FIGS. 1 and 2 , in a state in which the striking area 110 of the base block 100 is formed of a plane having a predetermined area, both the base block 100 and the flow block 200 have a chamfered edge. It can be seen that the treated chamfer portions 101 and 201 are provided.

Here, the fact that the striking area 110 is formed of a plane of a certain area prevents the problem that the tip of the Dangkyu cue slides easily when the striking area is struck, as described above, and an unnecessary force is transmitted to the flow block 200 .

In addition, the chamfer parts 101 and 201 serve to shape the user's concentration by cutting the corner of the striking area 110, which is one side, of the base block 100 of the hexahedron to make the striking area appear relatively smaller than the basic hexahedron. In addition to providing, the lower surface of the base block 100 and the area of the base block 100 and the seating surface of each of the flow blocks 200 are reduced to provide a relatively greater inertia to the flow block 200 to provide a more fine-grained user and can provide the ability to cultivate the training ability to require accurate strokes.

3 is a perspective view illustrating a weight block that can be coupled to the base block and the flow block, and an adhesive layer laminated on the bottom surface of the flow block.

Figure 3 is provided as an additional means for varying the weight of the base block 100 and the flow block 200, specifically, the exercise device of the present invention is the base block 100 and the flow block 200, respectively. and a detachable weight block 300 .

The weight block 300 is provided with a coupling part 310 on one side, and provides a detachable function through the coupling part 130 also formed on some surfaces of the base block 100 or the flow block 200. do.

Referring to FIG. 3 , a coupling part 130 , that is, a female coupling part that is a coupling hole is formed on the right side of the surface on which the striking area 110 of the base block 100 made of an exemplary hexahedron is formed, and the coupling part 310 is formed thereon. That is, it is possible to perform male and female coupling with the weight block 300 formed with a male coupling part such as a coupling protrusion.

In addition, the coupling part 210, that is, the coupling hole is formed on the bottom surface of the flow block 200 also made of a hexahedron, and the weight block 300 having the coupling part 310 (coupling protrusion) formed therein can be detachably male and female. have.

That is, the weight block 300 increases the weight of the base block 100 and the flow block 200 to increase the inertia generated in the flow block 200 according to the user's stroke force control state and the repulsive force ( It is to provide a function to control static friction force).

The weight block 300 is not necessarily formed in a panel shape as shown in FIG. 3 but may be formed in various three-dimensional shapes. can take shape. Through this, depending on the position of the coupling portion 310 of the weight block 300, one or two or more weight blocks 300 can be mounted on several surfaces of the base block 100 and the flow block 200. Of course.

4 is a perspective view illustrating a state in which a friction imparting layer is formed on a base block.

As mentioned above, a shock-absorbing material such as a sponge or an elastic pad may be added to the striking region 110 of the base block 100 , and in the present invention, this is referred to as a 'friction imparting layer 111 '.

As can be seen from FIG. 4 , the friction imparting layer 111 may cover the entire area of the striking area 110 or only a part thereof.

The friction-imparting layer 111 is based on a material that is different from the friction force of other parts of the base block 100 , and furthermore, it may be made of a material different from the hardness of other parts of the base block 100 .

That is, the friction-imparting layer 111 makes the hitting area 110 slippery or rough, as well as hard or soft, so that various friction-imparting layers 111 are stacked according to the skill and level of the user. Variability of the hitting area 110 may be provided to help improve stroke ability.

In other words, a friction imparting layer 111 having a material and properties that can easily prevent the flow block 200 from repulsing or generating inertia by absorbing a portion of the force applied during the stroke in the striking region 110 is provided to a beginner user The advanced user can apply various friction-imparting layers 111 to the hitting area 110 according to the user's skill in a manner that provides the friction-imparting layer 111 having the opposite property to the user's stroke ability. It is possible to help improve.

Additionally, although not shown in the drawings, the seating surface 120 of the base block 100 and the bottom surface of the flow block 200 may be formed of magnets that exert mutual attraction.

Here, the base block 100 and the flow block 200 as a whole may be made of a magnet, but a part of the base block 100 and the flow block 200, that is, the seating surface 120 of the base block 100 and the It is also possible to laminate a magnet layer or a magnet panel only on the bottom surface of the flow block 200 .

These two magnets are arranged to act as attractive forces with each other, for example, the exposed surface (outer surface) of the seating surface 120 of the base block 100 is the N pole, and the exposed surface of the bottom surface of the flow block 200 is It means that it can be arranged at the S pole.

According to this, it provides a function to adjust the inertia of the flow block 200 seated on the base block 100. Specifically, since the base block 100 and the flow block 200 are magnetically coupled, the user can use the stroke. It serves to prevent the flow block 200 from being easily separated from the base block 100 by the above-described magnetic force when hitting the striking area 110 .

This is mainly applicable for beginners or intermediates, that is, beginners or intermediates do not control the force well when executing a stroke through the billiard cue, so it is easy to relieve the flow block 200 from being separated from the base block 100. function can be provided.

In addition, although not shown in the drawings, an adhesive layer providing adhesive force is laminated on at least one of the seating surface 120 of the base block 100 and the bottom surface of the flow block 200 by the adhesive properties of the adhesive layer. It is also possible to provide a function of mitigating the separation of the flow block from the base block 100 easily by a principle similar to the above-described magnetic force.

Specifically, the adhesive layer may preferably have a surface friction force of 10 to 40N based on ASTM D1894 in a state containing ethylene vinyl acetate (EVA).

This adhesive layer is mainly provided for beginners or intermediate users, and it is possible to reduce the phenomenon that the flow block 200 is easily separated from the base block 100 during a user's stroke.

In other words, by adding a layer (adhesive layer) having an adhesive performance to the contact surface of each of the base block 100 and the flow block 200 so that both are adhered, the phenomenon of the flow block 200 falling due to inertia is reduced. It can be understood as enabling or reducing it.

Here, ethylene vinyl acetate (EVA) is a copolymer of an ethylene (ethylene) monomer and a vinyl acetate (VA) monomer, that is, a material produced by polymerization of the two monomers together. It has good thermal strength, stress crack resistance, ozone resistance, and excellent adhesion and workability.

That is, ethylene vinyl acetate has excellent variability in that transparency and melting temperature can vary depending on the content of vinyl acetate (VA), so sports goods, solar cell protection films, hot melt adhesives (Hot Melt Adhesive, HMA) It is applied to foam products such as shoe midsoles, rain boots, fishing floats, films, etc., and is widely used in industrial and household goods.

The adhesive layer of the present invention also applies ethylene vinyl acetate, which has such variability as well as adhesive strength, as a main component of the adhesive layer to provide a sticky adhesive property on the seating surface of the base block 100 or the bottom surface of the flow block 200. Because the flow block 200 easily falls by inertia, it serves to partially solve the problem that beginners or intermediates cannot concentrate on adjusting the stroke force.

In addition, in order to ensure that the surface friction force of the adhesive layer is 10 to 40N according to ASTM D1894, a known surface treatment process (plasma treatment method, corona discharge treatment method, etc.) is repeatedly learned through a try and error method. Then, each drive of the detailed configuration of the device that performs each process through a standard obtained based on the learning, that is, a look-up table (this device is a well-known device in each process, so a detailed description will be omitted) The method of setting the value can be applied.

Furthermore, the adhesive layer of the present invention adjusts the strength of the adhesive force and at the same time, the adhesive layer is formed on the base block 100 or the fluid block 200 to compensate for the spreadability of the adhesive agent containing ethylene glycol (ethylene glycol). It is possible to further include

In this case, the pressure-sensitive adhesive layer may include, for example, 5 to 15 parts by weight of an adhesion aid based on the total weight of the pressure-sensitive adhesive layer. This adhesive aid can be prepared in advance by a method to be described later, and then included in the adhesive layer before curing, and then the adhesive layer can be cured to finally prepare an adhesive layer containing the adhesive aid. .

Specifically, the adhesion aid may be manufactured through the first material preparation step (S100), the second material preparation step (S110), and the adhesion aid completion step (S120).

First, the first material preparation step (S100) is toluene (Toluene) 10 to 20 parts by weight, acetone (Acetone) 15 to 30 parts by weight, methyl ethyl ketone (Methyl Ethyl Ketone) 20 to 40 parts by weight, ethyl acetate (Ethyl Acetate) ) A process of preparing the first material by mixing 20 to 40 parts by weight, which is a process of preparing a solvent required for manufacturing an adhesive aid.

Here, toluene is a transparent colorless liquid with a characteristic fragrant odor and is used in the manufacture of aviation fuel and automobile fuel, solvents and other chemicals, and acetone is a volatile, flammable, transparent, colorless liquid with a irritating and slightly sweet odor. and methyl ethyl ketone is an alcohol oxide used as a solvent in industrial processes or as a material in the synthetic rubber industry, and ethyl acetate is a volatile and flammable colorless liquid as an ester component of ethyl alcohol and acetic acid.

Next, the second material preparation step (S110) is 20 to 35 parts by weight of NDI (1.5-Naphthalene diisocyanate), 20 to 35 parts by weight of blocked isocyanate, 10 to 20 parts by weight of ethylene glycol, MPD ( 3-Methyl-1,5-Pentanediol) is a process of preparing a second material by mixing 10 to 20 parts by weight and 15 to 30 parts by weight of an aqueous dispersion resin, and the step of completing the adhesive aid (S120) is 50 to 70 parts by weight of the first material Part, 20 to 45 parts by weight of the second material, and 0.5 to 5 parts by weight of DBTDL (di-n-butyl tin dilaurate) It is a process of finally completing the adhesive aid.

Here, NDI and block isocyanate are types of isocyanate, and ethylene glycol, MPD, and water-dispersion resin are types of polyols. When the isocyanate and polyol are reacted, polyurethane having a viscosity and tackiness of about 1,500 cps at 25°C is produced, and DBTDL serves as a reaction catalyst for the reaction between isocyanate and polyol. In addition, the water-dispersed resin is a material having the property of stickness and provides a function to adhere well to the object, and the blocked isocyanate is mixed with the water-dispersed resin to proceed with the urea reaction. However, by crosslinking through this reaction, it serves as a curing agent capable of accelerating the rate of curing and improving mechanical strength during curing. In addition, a specific manufacturing method of the water-dispersion resin will be described later.

The adhesive aid prepared through this process not only improves the adhesive function of the adhesive layer, but also has a high viscosity, so it can help to improve the spreadability and flowability of the adhesive layer. Alternatively, it may be applied to the seating surface of the flow block 200 with an appropriate thickness.

In addition, the above-described water-dispersion resin may be prepared through an intermediate material preparation step and a water-dispersion resin completion step.

First, the intermediate material preparation step is a process of preparing an intermediate solution by mixing 85 to 99 parts by weight of water and 1 to 15 parts by weight of an emulsifier, followed by stirring at a speed of 800 to 1200 rpm for 20 to 50 minutes. Here, it is preferable to use tertiary distilled water (water purified by passing through an ultra filter) as the water. In addition, the emulsifier encloses the molecules in the solution to prevent aggregation by colliding between the molecules and provides stability, and PEG-PPG-PEG (Poly(ethylene glycol)-block-poly (propylene glycol)-block-poly(ethylene glycol)) may be used.

Next, the water dispersion resin completion step is a process of mixing 45 to 60 parts by weight of the intermediate solution and 40 to 55 parts by weight of the polyaspartic resin, followed by stirring at a speed of 1800 to 2200 rpm for 2 to 5 hours to complete the water dispersion resin. Here, the polyaspartic resin is a material that can be obtained as a coating agent in the market, and is a coating material that has excellent resistance and durability to ultraviolet rays and can be dried quickly.

The water-dispersion resin thus prepared improves the durability of the adhesive layer while being included as a manufacturing component of the adhesive aid to prevent the adhesive layer from easily losing adhesive strength when the base block 100 and the fluid block 200 come into frequent contact with each other. , provides a property that can shorten the drying rate after application of the adhesive layer.

6 is a perspective view showing a display for displaying the impact of the base block.

As can be seen from FIG. 6 , the base block 100 may include an impact sensor 140 and a display 150 .

The impact sensor 140 performs a function of detecting an impact applied to the striking area by the user's stroke in a state mounted on one side of the periphery of the striking area 110 . At this time, since the impact sensor 140 can apply a known impact sensor, a separate description of the specific structure thereof will be omitted.

The display 150 is formed on one side of the striking area 110 or on a surface different from the surface on which the striking area 110 is formed for impact protection. function to display. Here, the impact value is not necessarily an absolute number including the impact unit, but it can also be derived by converting it into a relative value.

In addition, the base block 100 may include a power supply unit (not shown) such as a battery mounting unit or an external power connection terminal for supplying power to the impact sensor 140 and the display 150 .

According to this structure, since the user can directly check the impact applied by himself/herself as a visual numerical value, it is possible to provide a basis for conveniently correcting the stroke force control more than visually confirming the drop of the flow block 200. can

7 is a conceptual diagram illustrating an embodiment of transmitting an impact of a base block to a user terminal.

The embodiment of FIG. 7 outputs the above-described shock value through the user terminal 400 (eg, a smartphone) having a display, and the base block 100 is not so large in size as shown in FIG. It can be said that it is prepared and supplemented the case where it is difficult to mount the display 150 .

Specifically, the base block 100 includes a communication unit 160 , an impact detection sensor 140 , and an impact value providing unit 170 .

The shock sensor 140 will be the same as the embodiment of FIG. 6 described above, and the communication unit 160 provides a function of maintaining a communication state with the user terminal, and the most common example is short-range communication with the user terminal 400 . It can be said that it is a Bluetooth communication module that does

The shock value providing unit 170 calculates the shock sensed by the shock sensor 140 as a shock value and transmits it to the user terminal via the communication unit 140 .

Through this, when the user terminal 400 is generally referred to as a smart phone, it is possible to visually output the shock value transmitted from the shock value providing unit 170 to the user through the display of the smartphone.

In summary, according to the embodiment of FIGS. 6 and 7 , the amount of impact that the user himself hits in a state in which the display 150 is provided on the base block 100 or communicated with the user terminal 400 is directly converted to a visual impact value. Since the output is output, if the flow block 200 continues to fall during multiple strokes, the user can be presented with a more specific correction method such as how much force should be further reduced, providing a basis for building an efficient practice environment can do.

As described so far, although the configuration and operation of the device for practicing the stroke control of billiard cues according to the present invention have been expressed in the above description and drawings, this is merely an example and the spirit of the present invention is not limited to the above description and drawings. , of course, various changes and modifications are possible without departing from the technical spirit of the present invention.
