Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a beat board. More specifically, the present invention relates to a beat board suitable for various swimming exercises.

(Prior art) As is well known, beat boards made of foam are used for swimming practice. Previous beat boards were so large that when the front ends were held with both hands and the arms were extended, the back part was It is formed so that it is located between the elbow and shoulder. That is, the front and rear lengths are relatively short, and there are no grooves penetrating the front and back sides. Therefore, when practicing crawl breathing, instead of grasping both front ends of the beat board with both hands as you do when practicing flutter, hold the beat board by pressing one side of the beat board with the palm of one hand. , while paddling the water with the other arm, perform various exercises related to breathing, such as the timing and rhythm between breaths, over several beat boards, but with this method, which used the beat board in the past, it was easy to lose your posture during practice. In this case, since there is no place to firmly grasp the beat board, the beat board is easier to escape from than the practitioner due to the buoyancy of the beat board itself. Also, for beginners in sidestroke, hold the center of the front of the beat board with one hand and practice paddling the water or moving your legs with the other arm. If the length is so short that when you hold the beat board with both hands and extend your arm, the back of the board will be located midway between your elbow and shoulder. This method using a beat board does not repair correct sidestroke form. Furthermore, when practicing various swimming styles such as crawl and butterfly, a beat board is placed between the legs to obtain appropriate buoyancy, and each stroke is practiced using only the arms. Its length is such that when the front end is held with both hands and the arm is extended, the rear part is located between the elbow and the shoulder, so the area that gets caught between the legs is relatively small. Therefore, it is easy to escape from between the legs during practice.

Therefore, in order to eliminate various disadvantages of conventional beat plates, a beat plate having a relatively long front and back length and having openings penetrating the front and back sides has been proposed. For example, Utility Model 57-93355 and Utility Model 59-119857
etc.

(Problems to be solved by the invention) According to these techniques, the above points can be solved to some extent. However, in the prior art, the water outlet is used instead of a hole to form a gripping part, and the hole is used to grip the gripper, making it difficult to grip the gripper.Therefore, a further improvement is required. Also, the width is simply the same from front to back, but there is too much width to fulfill the function of preventing the elbows from bending, so further improvements are desired in this respect as well. However, since the width is the same from front to back, and when it is held between the legs, the pinch area increases, and it also has too much buoyancy, so it is difficult to hold it between the legs, so further improvement is desired. It can be done. In particular, since it is simply the same width from front to back and is long, there is no part to grab with both hands when practicing flutter, making it invincible for basic flutter training.

(Purpose) Therefore, the purpose of the present invention is to better enable breathing exercises for crawling, to more effectively prevent elbow bending when practicing sidestroke for beginners,
You can practice splashing water with just your arms more effectively,
Furthermore, it is an object of the present invention to provide a beat board suitable for practicing flapping.

(Means for Solving the Problems) In order to achieve the above object, the present invention is designed so that when both ends of the front part 2 are grasped with both hands and the arms are extended, the rear part 3 is located between the elbow and the shoulder. It has a beat board main body 1 made of foam formed to a size, and has a plurality of grooves 6A, 6B, 6C that penetrate through the front and back of the surface of the beat board main body 1 and into which fingers can be inserted, and the plurality of grooves 6A. , 6B, 6C, a plurality of gripping parts 7A, 7B, 7C are formed alternately with grooves, and an elbow rest auxiliary plate 8 is provided in front of the front part 2 of the beat board main body 1.
The grooves 6A, 6B, 6C and the gripping portions 7A, 7B, 7
Each of C is perpendicular to the surfaces 4 and 5 and perpendicular to the length direction L, and is formed parallel to each other with appropriate intervals,
The width of the auxiliary plate 8 is set to be narrower than the width of the beat main body 1 to the extent that the arm can be placed on it, so that grip portions 9A and 9B are provided on the left and right sides of the boundary between the beat plate main body 1 and the elbow rest auxiliary plate 8, respectively. This is a beat board characterized by the formation of a .

(Function) The function of the present invention will be described in accordance with the process by which inconveniences in practicing using a conventional beat board are solved by using the beat board having the above-mentioned configuration.
That is, in the crawl breathing exercise, the beat board is held by inserting the fingers into the grooves 6A, 6B, and 6C of the beat board main body 1 and grasping the gripping parts 7A, 7B, and 7C. Grooves 6A, 6B, 6C
Gripping portions 7A, 7B, and 7C that are parallel to each other are formed alternately. Therefore, it is easy to grasp. Therefore, you can hold it firmly and the beat board will not run away from the practitioner.

When practicing sidestroke for beginners, reverse the front and back of the beat board so that the elbow rest auxiliary board 8 is in front of you, and the tip of the elbow rest auxiliary board 8 is near your armpit with your arm extended. Use the method of inserting your fingers into the groove and grasping the gripping part. According to this method, the beat board main body 1 and the beat board main body 1 of one arm holding the beat board from the finger to the armpit area are
Since the elbow rest auxiliary plate 8 extended to the upper part supports the elbow, it is possible to keep the elbow straight, and the user can learn the correct sidestroke form without bending the elbow as in conventional practice using a beat board. can.
In particular, the auxiliary plate 8 is set to have a width sufficient for resting the arm, and since there is no excess or deficiency, the bending of the elbow is intentionally restricted, and there is no extra width, so there is no excessive water resistance.

When practicing throwing water with just your arms, the area that gets caught between your legs is larger than that of a traditional beat board, so even if your posture collapses, you are less likely to run away from the practitioner. Become.
In particular, the auxiliary plate 8 only increases the area in contact with the legs when pinched, and does not unnecessarily increase the buoyancy, so the beat plate does not easily escape from between the legs. Furthermore, when practicing flutter, the grips 9 at both left and right ends near the boundary between the beat board main body 1 and the elbow rest auxiliary board 8 are used.
A, 9B, and the length of this beat board body is such that when you hold both ends of the front part with both hands and extend your arms, the rear part is located between the elbow and shoulder, so you can use a conventional beat board. If you use it, you can do similar exercises.

(Example) Next, an example of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a beat plate body made of foam and having a predetermined thickness. In other words, the length L from the front part 2 to the rear part 3 is set so that when the front part 2 grips both ends with both hands and extends the arm, the rear part 3 is located about halfway between the elbow and shoulder of the person holding it. This is what is being done. The above shows conventional parts, and the present invention is made as follows to achieve the above object. That is, (A) a plurality of grooves 6A, 6B, 6C penetrating between the surfaces 4 and 5 of the beat board main body 1 and into which fingers can fit, and a plurality of gripping portions 7 arranged alternately with the grooves between the plurality of grooves;
Form A, 7B, and 7C. Each of the grooves and gripping portions are perpendicular to the surfaces 4 and 5, and are formed parallel to each other at appropriate intervals so as to be perpendicular to the length direction L. That is, not only are the grooves 6A, 6B, and 6C formed, but also a plurality of gripping portions 7A, 7B, and 7C are formed in parallel between the grooves 6A, 6B, and 6C, and are perpendicular to the length direction L.

(B) In front of the front part 2 of the beat board main body 1, an elbow rest auxiliary plate 8 is integrally extended, which has the same thickness as the beat board main body 1, the required length, and is narrow enough to place an arm on. Set up Then, hold the beat board main body 1 at the left and right ends of the elbow rest auxiliary board 8 at the grip portions 9A and 9, respectively.
It is formed as B. Note that 10 is the tip of the elbow rest auxiliary plate 8.

Next, swimming practice using the beat board according to the present invention will be specifically described.

FIG. 5 is an example of using the original beat board in flapping training. In this example, the grip portions 9 at both left and right ends near the boundary between the beat board main body 1 and the elbow rest auxiliary board 8 are
You will have to grab A and 9B, and this beat board body 1
The length of the beat board is such that when you hold both ends of the front part with both hands and extend your arms, the back part is located between your elbows and shoulders, so you can perform similar exercises using a conventional beat board. This point is significantly different from the conventional method.

Figure 6 is an example of using the original beat board in breathing exercises for crawling. In this example, the beat board is held by inserting the finger of one hand into an arbitrary groove (6C in this figure) on the beat board body, grasping an arbitrary grip part (7D in this figure), and holding the beat board with the other arm. While strumming, perform various breathing exercises over a few beats.
According to this method, even if the practitioner loses his or her posture during practice, the beat board is firmly grasped, so the beat board will not escape from the practitioner, unlike conventional beat boards. That is, there are not simply openings penetrating the front and back sides, but gripping portions 7A, 7B, and 7C that can be grasped with fingers no matter which groove is selected. Since they are perpendicular and parallel to the length direction L, you can choose the species according to the length of your arm.

FIG. 7 is an example of the use of the original beat board in horizontal stroke practice for beginners. In this example, the front and back of the beat board are reversed, the elbow rest auxiliary board 8 is placed in front of you, and an appropriate groove (6A in this figure) is placed so that the tip 10 of the elbow rest auxiliary board 8 is near the armpit when the arm is extended. ), grab the grip part (7A in this figure), and use the other arm or leg to swim. According to this method, the arm holding the beat board from the fingers to the armpit is supported by the beat board body and the elbow rest auxiliary plate extended to the beat board body, so the elbow is not stretched out. This allows the practitioner to acquire the correct sidestroke form without bending his or her elbows like in traditional practice using a beat board, even if the practitioner's hand is straining to grip the beat board. In this figure, the grip portion 7A closest to the user is gripped, but it is possible to select any grip portion depending on the length of the practitioner's arm. In particular, the auxiliary board 8 is narrower than the beat board main body 1, and is wide enough to place the arm on, so the bending of the elbow can be intentionally controlled so that it does not go out of that width, and in addition, excess water can be There is no resistance.

Fig. 8 shows an example of using the proposed beat board to practice swimming with only the arms.The beat board is placed between the legs to obtain appropriate buoyancy and the player practices using only the arms. In this example, since the area between the legs becomes larger, it is less likely that the person will run away from the practitioner even if the person's posture collapses. In particular, since the auxiliary plate 8 is narrow, no extra buoyancy is applied, and the beat plate does not escape from between the legs.

In some cases, even in the above-mentioned crawl breathing exercise example shown in Figure 6, it is possible to use the beat board with the front and back reversed, as in the beginner's sidestroke exercise example shown in Figure 7. be.

(Effects of the device) As detailed above, the device of the present invention is easy to grip with the fingers during crawl breathing exercises, so the beat board does not escape from the practitioner, and it is useful for beginners when practicing horizontal elongation. This allows you to learn the correct sidestroke form without bending your elbows, and because of this, there is no unnecessary water resistance, and when practicing swimming with only your arms, you can easily maintain the beat even if your posture collapses. A beat board that rarely escapes from the practitioner, does not create any extra buoyancy, and can be gripped with both fingers when practicing flutter, making it possible to practice more effectively. It provides:
