Description

Racket game set and its play method for narrow space

The present invention relates to a racket game set and a method of playing the same that enable the exercise using the racket in a narrow indoor space.

In general, a game using a racket includes tennis, badminton, squash, and speed minton.In a game using such a racket, a racquet, a ball, and a court are required, and a net is selectively used according to the game. Instead of being used in other races, these supplies form one set for the race, and each race has its own specifications for the size and weight of the racquet and for the race.

Among these, the articles constituting the badminton match set will be described in more detail below.

First, as shown in Fig. 1, the racket has a handle 2, a string portion 4, a base 6 provided with the string portion 4, and an impact force at the time of hitting the shuttlecock. It consists of a shaft 8 formed in a hollow, a throat 9, the total length of which does not exceed 680 mm, the overall width of the string part 4, including the handle 2 part in the range of 200-250 mm. The length should be within 280mm in total length and 220mm in width, the shaft diameter is 7-8.5mm, and the cross section thickness is 1.5-2.5mm.

As shown in Fig. 2, the shuttlecock is inserted with a bird feather 20 into a base 10 made of a hemispherical cork. The shuttlecock weighs 4.5-5.5 g and has a diameter of 2.5-2.8 cm. , The number of feathers should be 16 pieces, the length from the end of the feather to the upper surface of the base should be 6.4 ~ 7.0cm, the diameter of the feather tip is 58-68mm, the upper surface of the base 10 and the outer surface of the feather 20 are 65 It will have an angle of about 75 ° to 75 °, a maximum speed of 320km / h, and the player must fall between 53 and 99cm inside the opposite back boundary line by hitting the underhand at one end of the court.

As shown in Fig. 3, the coat is formed in a length of 13.4m in width and 6.1m in length in consideration of the flight distance of the shuttlecock when the racket and shuttlecock are used, and the net is configured to have a height of 155cm.

However, the badminton is relatively lighter than the tennis ball and the feathers are opened at a certain angle, so the wind is affected by the wind, so even if the outdoor is weak, the shuttlecock cannot fly in the desired direction and distance. All must be done in a blocked indoor stadium. In this case, the ceiling height should be at least 9m to ensure the flight distance and flight height of the shuttlecock.

As such, the existing badminton game requires a space having a ceiling height and an area of 9m or more, which is difficult to secure the interior space of a general building, and thus, it is difficult to secure a game space, which is a problem in popular diffusion.

In addition, the conventional racket has a long length, it is difficult for the general public who is not a professional athlete to accurately match the shuttlecock to the string part, and thus, the shuttlecock cannot be accurately matched, so only the shuttlecock is focused on the racket, including hand movements and steps. There was a problem that the posture is not right, the body comes to the joints after exercise, for example, there was a problem that tennis elbow occurs.

The above-mentioned tennis elbow is caused by the vibrations of the ball or shuttlecock hitting the racket that stimulates the arm.If you use too heavy racket or the grip size is not correct, This may occur even if the joule's strength is not adequate.

Meanwhile, in order to solve the problem of badminton receiving a lot of wind resistance, speedminton, which combines badminton and tennis, is widely used, which uses a speeder with a heavy rubber base to reduce wind resistance. will be.

However, these speedminton's speeders are heavier than shuttlecocks and have a bad effect on the joints, and because they are fast, they are not suitable for the elderly and children, and the court size also uses 5.5m squares with 12.8m space, totaling 23.8m There is a problem that it is difficult to secure the indoor space because the space is required.

In addition, the Republic of Korea Patent Publication No. 10-2004-0025507 discloses a technology that can be played indoors and shortened the dimensions of the racket as compared to the conventional so as not to burden the elderly or children, it uses the conventional racket material as it is While simply shortening the length of the racket, the description of the dimensions of the material such as width and diameter can not be found in the detailed description of the specification, there is no description of the badminton shuttlecock, it is judged that the conventional shuttlecock is used as it is. .

However, as described above, when the conventional racket material is used as it is, the diameter is the same but only the length is shortened, thereby reducing the elastic force and the impact absorption force. As a result, even when hitting with the same force as in the case of using a conventional racket, the flying distance is significantly shortened, so a lot of force is required to obtain the same flying distance, which is not suitable for a child or an elderly person, and an impact force generated when an impact with a shuttlecock occurs. As it is transmitted to the user through the handle as it is, the joints become crowded, and since the elastic force is not generated in the shaft, the shuttlecock bounces when it hits the racket, so play in a narrow space requiring elaboration, especially hairpins and drives It was difficult to use accurate smashing, returning, etc., and the power of smashing was not loaded so that the game lost interest.

On the other hand, the most important thing is the flight distance of the shuttlecock in order to proceed with the racket game in a narrow indoor space.

However, in order to reduce the flight distance of the shuttlecock as described above, it is important to properly adjust the dimensions and weight of the feather and the base, but in the prior art, no embodiment for reducing the flight distance has been found.

In addition, simply reducing the dimensions of the conventional badminton shuttlecock is not only difficult to obtain the desired flight distance, but also difficult to maintain a stable flight curve.

For example, if the size of the feather is smaller than that of the conventional badminton shuttlecock, the shuttlecock may not hold the center properly during the flight, preventing the shuttlecock from flying steadily, and the feather size will be relatively small compared to the base. There was a problem that the less the flight distance of the shuttlecock longer than before. In addition, if the size of the feather is left intact, but the base is manufactured in a smaller size than the conventional one, the flight distance becomes shorter as the weight becomes lighter, but the size of the feather becomes too large compared to the base, resulting in too much air resistance during the flight, resulting in too short a flight distance. There was a problem.

The present invention to improve the problems of the racket game using a shuttlecock, including the conventional badminton as described above, so as not to overdo the joints while ensuring sufficient movement effect and the game even in a narrow indoor space, the damage of the shuttlecock It is an object of the present invention to provide a racket set and a method of playing the same, which may reduce the rate.

Features of the present invention for achieving the above object, the diameter of the base is 16-23mm, the vertical length of the base is 14-21mm, the vertical length is 50-80mm from the lower end of the base to the upper end of the feather, the end of the feather A shuttlecock having a diameter of 40-60 mm, 10-14 feathers, and a weight of 1.5-3 g; A racket having a total length of 430-470 mm, a total width of 150-185 mm, and a length of a string portion of 200-225 mm; Both sides of the back boundary line length 500 ~ 1,000cm, overall width 250 ~ 500cm, women's singles: men's singles and doubles sideline width difference 30 ~ 43cm, subline 100 ~ 140cm from center; A net along the width of the coat, with a top height of 120-150 cm; And a post for installing the net.

In order to adjust the flight distance of the shuttlecock in the above-described configuration, one or more of the dimensions of the feather and the dimensions of the base are selected and adjusted within the above range, or the weight is adjusted by varying the porosity of the cork constituting the base of the shuttlecock. Alternatively, adjust the weight by adjusting the number of times the adhesive is applied to the base and feather connections.

As an example of adjusting the base porosity of the shuttlecock, natural cork and artificial cork are laminated, or artificial cork with different porosity is laminated, but the porosity is selected and used according to the weight of the desired shuttlecock, for example, natural cork and artificial cork are laminated. In the case, natural cork is placed at the point of impact, and artificial cork has a porosity different from that of artificial cork, and artificial cork having a porosity corresponding to natural cork is disposed at the point of impact. Therefore, artificial cork having an appropriate porosity is selected and used.

And, the post is formed to be adjustable in length to adjust the height of the net.

Another characteristic of the present invention is that the racket and shuttlecock are used as it is, and the coat and net are set by proportionally adjusting the overall width, length and height within the minimum and maximum dimension ranges to fit the indoor space, and the subline Shuttlecock in the space between the back boundary line and the shuttle cock dropped inside the other back boundary line is considered valid service, and the flying shuttle cock hits the racket within the effective back boundary line and sideline of the opponent from the net. There is another feature of the racket game method of repeating the receiving action to hit the racket so that it falls.

In addition, the racket game method has another feature in that the opponent to score in the case of deviation from the provision of the service and receive.

Look at the effect of the present invention configured as described above.

First, since shuttlecocks' flight distance is shorter than conventional racquet games including badminton and flight altitude is also low, the racquet game can be enjoyed in the interior space of general buildings with ceiling height of 3m-4m. It is possible to enjoy a racket game anytime and anywhere without restrictions, which has a great effect on the spread of racket games.

This is because the racket is short, the shuttlecock is lighter, the angle between the feather and the upper surface of the base is wider than the conventional feather, because the flight speed and altitude decreases due to the resistance during the flight.

Second, as the number of feathers decreases and the diameter, overall size and total weight of the base become smaller, the shuttlecock becomes lighter, and the racket also has sufficient elasticity with a drastically reduced dimension as compared to the prior art. Prevent joint damage. In addition, the racket is shortened to easily fit the shuttlecock, so you can pay attention to the correct arm movements or foot movements, there is an effect that can prevent going to the body, including joints due to incorrect arm movements and foot movements.

Moreover, as described above, the burden of the load is reduced, so that everyone of all ages, such as the elderly and children, can enjoy the game.

Third, because the racket adds elasticity to the shuttlecock when it hits, the shuttlecock is loaded with force, so that the flight distance is improved compared to the racket made by simply shortening the length, so that excessive movement is not required, such as smashing, and accurate play is possible. This makes the game fun, so you can get enough exercise for all ages.

Moreover, the narrower the court, the shorter the time from hitting to hitting again after receiving the opponent's receive, which increases movement and requires more action for faster and more powerful matches with smaller rackets and shuttlecocks. Therefore, a lot of exercise is also suitable for users who require a large amount of exercise, such as young adults.

Fourth, as the length of the racket is shortened, the impact force applied to the hitting the shuttlecock is reduced, and the breakdown rate of the shuttlecock is greatly reduced as compared to the conventional racket, and the shuttlecock is disposed of upon breakage, but according to the racket of the present invention, the disposal rate of the shuttlecock is greatly reduced. Not only is there a resource-saving effect, it also greatly reduces the cost of purchasing shuttlecocks.

Fifth, because it uses a light and small racket, it is easy to carry, so you can do exercises such as stretching or posture correction using the racket anytime, anywhere, and it is also possible to practice posture for badminton, tennis, and speedminton using the racket. have.

Hereinafter, an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

4a to 8 are views showing a racket game set according to the present invention, Figure 9 is a view showing the trajectory of the shuttlecock when using the racket game set of the prior art and the racket game set of the present invention.

The racket game set according to the present invention is largely composed of a racket 100 and a shuttlecock 200, a net 300, a coat 400, and a post 310.

In the above, the racket 100 has a weight in the range of 50g-70g in order not to go out much of the distance of the shuttlecock 200, as shown in FIG. 4A, with a total length of 430-470mm, a total width of 150-185mm, and a string part ( The length of the 110 is 200-225mm, and the dimensions of the handle 120, the shaft 130 and the throat 140 are adjusted in the total range of 230mm-255mm.

The shaft 130 has a diameter of 5-7 mm and a cross-sectional thickness of 0.5-1.5 mm, as shown in Fig. 4B.

In addition, the size of the handle 120 is 90-160mm, which is intended to minimize the size of the handle while the inconvenience does not occur when holding the handle.

And, the interval of the string is to be a square with one side is 0.6-1.2cm, which is to be described later as the shuttlecock narrower as the size is reduced so that the shuttlecock is not caught between the strings at the time of hitting.

5, the diameter of the base 210 is 16 to 23 mm, the vertical length of the base 210 is 14 to 21 mm, and the lower end of the base 210 to the upper end of the feather 220, as shown in FIG. The vertical length of the 50-80mm, the end diameter of the feather 220 is 40-60mm, the feather 220 is used 10-14 pieces, the weight is 1.5-3g.

The weight is determined by adjusting one or more of the dimensions of the feather, the dimensions of the base and the weight of the base to adjust within the above-described weight range, mainly determines the weight of the entire shuttlecock as the material of the base.

As the structure for determining the weight by the material of the base, as shown in Fig. 5 in the process of manufacturing the base, the cork constituting the base is bonded to the artificial cork and natural cork with an adhesive and laminated, but artificial for the weight adjustment By varying the foaming rate of the cork to have a different porosity, the artificial cork having a porosity suitable for the weight to be produced is selected and used.

As an example, to increase the weight, a foam having a small porosity of artificial cork is used, and to foam a small weight, a foam having a large porosity of artificial cork is used.

At this time, by placing a natural cork at the lower end of the base 210, that is, hitting point so that the feel is not lowered.

Then, after laminating the natural cork and the artificial cork as described above, it is molded according to the shape of the base 210, and covered with a urethane-coated fabric as the outer shell to complete the base manufacturing.

The shuttlecock thus manufactured shall not exceed 7.5m in length from the point of hitting to the point of landing when hitting with full understroke.

In another embodiment, when the artificial cork having different porosity is laminated, the impact point, that is, the artificial cork positioned at the lower side, has a porosity similar to that of natural cork, and the artificial cork positioned at the upper side thereof is adjusted to have a desired weight. Artificial cork with porosity is used.

In addition, the cork may be used by laminating two or three or more sheets.

On the other hand, if the desired weight can not be adjusted only by adjusting the porosity, it is possible to adjust the number of times the adhesive is applied to the connection portion of the base, that is, the upper portion of the base. For example, the desired size is adjusted by adjusting the size of the feather and the size and porosity of the base. If it is less than, the adhesive is usually applied only once on the upper surface of the base, but by double coating, the weight can be compensated for.

In addition, the shuttlecock should not exceed 7.5m in length from the hitting point to the landing point when hitting the full understroke using the racket.

As shown in Fig. 6, the net 300 has a height of 1.2 m to 1.5 m, the width corresponds to the size of the coat, and the mesh of the net has a square with one side of 1 to 1.8 cm.

On the other hand, in order to use the net 300 to fit the width of the coat, the net is formed differently (for example 500m, 600m, 700m, 1000m, etc.).

As shown in FIG. 7, the coat 400 has a distance between the length of both side back boundary lines 410 of 5-10 m, width of both side lines 420 of 2.5 to 5 m, and a service line 430 around the net. Silver 1 ~ 1.4m, the sideline 420a for the excitation fastening is located at a position of 0.3 ~ 0.43m respectively inward from both sidelines.

The coat 400 may be applied to the fixed floor surface with the ink or the like according to the above-described dimensions, it is formed as a unit and assembled to each other to be applied on the flooring having a cushion to form the floor surface of the stadium It may be manufactured and assembled.

The post 310 is installed to be adjustable in length to adjust the height of the net, the post 310 may be fixedly installed on the floor, the portion responsible for the load is installed to be movable May be

As an example, as shown in FIG. 8, the post is formed as a double tube of the inner tube 312 and the outer tube 314, and a plurality of adjusting holes 312a and 314a are spaced at the same interval between the inner and outer tubes 312 and 314. Perforated), the lower part is provided with a weight body 316 so as not to move when standing on the ground. The post formed as described above adjusts the position of the inner tube 312 and inserts the fixing means 318 into the adjusting holes 312a and 314a at the corresponding position, thereby adjusting the installation height of the net.

In addition, the height of the post can be adjusted in various ways. For example, the above-described adjustment hole may be formed only in the outer tube to adjust the height, and then fix the position by tightening the bolt at the adjusted height. Depending on the height to be formed and installed, the post may be assembled using a fastening means such as bolts with an appropriate number.

According to the racket game set configured as described above, as the length of the racket becomes shorter and the hitting position of the racket and shuttlecock is closer to the body, it is easy to align the shuttlecock with the racket, and the flying position of the shuttlecock is lowered because the hitting position is low.

In addition, the size of the shuttlecock is greatly reduced the size of the base and the number of feathers, the overall size is smaller and the weight is significantly reduced compared to the prior art is lower than the conventional flight height and short flight distance.

Looking at such a mileage and height with reference to Figure 9, the dotted line of Figure 9 shows the flight trajectory when using the conventional badminton racket and shuttlecock in the long high service, the solid line in the long high service using the racket and shuttlecock of the present invention By showing the flight trajectory of the shuttlecock, it can be seen that the flight trajectory of the present invention is lower and shorter than in the prior art.

Accordingly, when the shuttlecock and the racket of the present invention are used, the flight height of the shuttlecock is lowered and the flight distance is shortened, so that the movement can be performed indoors, and the game can be performed in a room having a height of 3-4 m.

It looks at the playing method using the racket game set configured as described above.

In the method of playing using the racket game set, the racket is used as it is, and the court and the net are proportionally adjusted to the overall line and height within the minimum and maximum dimensions to fit the size of the indoor space and the purpose of the exercise. Set the weight of shuttlecock to suit the set coat.

Such a racket playing method shall be considered as an effective service when the shuttlecock falls inside the opposite back boundary line by hitting the shuttlecock with the racket in the space between the subline and the back boundary line, and hitting the flying shuttlecock with the racket to activate the opponent's back from the net. Repeating the hitting with the racket so that the shuttle cock falls in the boundary line and side line.

In addition, in the racket game method, if the service and the rule of the receiver deviate, the opponent scores.

These racket playing methods are divided into full-court games and half-court sports. In the case of a full-court game, a court may be composed of the maximum dimensions in the above-described court and net dimensions. In the case of an exercise, the coat only needs to be composed of the minimum of the coat's dimensions.

Let's look at an example of a full court game.

First, in the case of men's doubles, the court shall be 1,000cm long and 500cm wide, with the 1,000cm line as the subline and the net height as 150cm, and the service shall recognize the effective space from the subline to the opposite back boundary line.

The male singles and the female doubles follow the same coat and net size as the male doubles described above.

On the other hand, in the case of women's singles, the length of the coat is 1,000 cm and the width is 43 cm from both ends to the inside, compared to the men's doubles, and the service effective space is the same as the men's doubles.

On the other hand, in the case of the half-court exercise, by stretching using the equipment (racquet), using the shuttlecock, and repeating the service and receive, and then stretching again, first make the footwork dance (movement) It allows you to warm up enough to reduce the injury rate and improve the exercise effect during the game, and to finish the stretch using the racket again after the game.

Examples of the regulations used in the racket playing method according to the present invention will be described in more detail below.

Player

The racket game method of the present invention is divided into a men's and women's singles, doubles and mixed doubles, singles for each one person, doubles for each pair of two people.

2. Toss

Both sides will toss before the match and the winning side will choose either the first sub or the court option, and the other side will choose the rest.

3. Score

①. The rule is to win 3 games (2 wins), and the first player to win 21 points (17 points for elementary school) wins.

②. The winner wins the rally. (I.e. one-way scoring without sub right)

③. In the case of a 21-point game, the player who scored two consecutive points in a 20:20 tie wins and the player who first reaches 31 points in 30:30 wins.

4. Coat change

After the end of the first game, before the start of the third game, and in the third game, the court is changed to 11 points first in case of 21 points, and 16 points in the case of 31 points.

5. Service

Look for the correct service.

Servers and receivers must stand diagonally in both service courts.

Shuttlecocks must be played under the server's waist.

Shuttlecocks must fall within the receiver's court.

-The entire head of the racket should be located below the server's hand so that it can be clearly identified at the moment of hitting the shuttlecock.

6. Single game

①. If the server has not scored points or if the score is even, the server will service it on the right.

②. The receiver receives on the court in the diagonal position of the server.

7. Doubles Method

①. Service and receive

Iii. If the server has not scored points or if the score is even, the server will service it on the right.

Ii. The player who stands diagonally on the service court from the server becomes the receiver.

Iii. Players on the receiver's side will not switch positions between the courts until the player has served and scored.

②. Scoring and Service Rights

Iii. If the receiving side commits a fault or is interrupted by the room, the service side obtains a score and the server serves the service again.

Ii. If the service side commits a fault or is interrupted by a crime room, the receiving side gains the score and the receiver side becomes the server (granting one service right to one side).

③. Serving

-In any game, the service entitlement continues as follows.

Iii. From the first server that started the match

Ii. Pass on to Sun Receiver's partner. The service then starts from the left service court

Iii. To the player on the court who meets the score

Iii. First, to the player on the court that meets the score of the receiving side and repeats as above.

8. Fouls

A foul is declared if

-If the service is not correct

-If the server fails to hit the shuttlecock while servicing,

-If the shuttlecock falls outside the court or passes between the nets and / or nets during the game.

-If the Shoocock touches any place other than the player's racket or net.

-If the shuttlecock has crossed the net before hitting the net or hit the shuttlecock in vain. However, if the shuttlecock crosses the net, the shuttlecock is allowed to cross the opponent's court.

-If the racket or player's body touches the net

-If you hit the shuttlecock more than once in a row

9. Lets (suspended and void)

-If a Let is declared, the serve of the player who served immediately before will be valid and will be served again by that player.

Letts are declared when a match is interrupted due to unforeseen accidents and actions. In other words, if the receiver is not ready for service, or if a shuttlecock enters the court during the game and interferes with the game.

10. Rules of Continuation

-If one side of each game reaches 11 points (elementary -9 points) first, an interval of less than 60 seconds is allowed.

An interval of less than 120 seconds is allowed between 1 and 2 games and between 2 and 3 games.

11. Advise and Breakaway from Court

-Athletes may receive coaching during a race only if they are not in progress.

-Competitors may not leave the court without the referee's consent until the end of the match.

12. Rally Point

Each time you win a rally, you score points. When a receiving team wins a rally, they don't just take the sub-rights, but they score points with just one attack and every room. In other words, each time a player serves or receives a rally, he earns a point and wins the sub-volume. In addition, the rally goes over to the opponent along with the run-off in the rally.

On the other hand, looking at the reasons for the division of the full coat and half coat as described above, the full coat is full of speedy and thrilling, the active range is wider than the half coat is suitable for young people to enjoy, half coat is full range activity It is relatively narrower than the other, but close to the other side can be a quick step with a quick play with a large amount of exercise, but it does not burden the joints, because it is suitable for the elderly or practicing or correcting the posture.

In addition to the full-court and half-court races described above, the size of the courts and nets may be adjusted proportionally within the minimum and maximum ranges to match the size of the indoor space, in which case the weight of the shuttlecock is measured by the size of the court. It can be adjusted to fit.
