Description

Auxiliary Apparatus for Swimming

The present invention relates to a swimming aiding aid worn on the ankle when swimming. Specifically, it can be worn on both ankles when swimming so as not to move with both legs gathered so as to maximize the effect of correction and training of swimming arm motion It is an ankle-wearing swimming aid which can increase the resistance to water when the wearer moves forward while floating in water by buoyancy and double the exercise effect.

When swimming, you can concentrate on the movements of both arms, increase the momentum of both arms, or use both arms and hands to focus on the action of pushing backwards efficiently by catching the water on the front, In order to correct it, it is sometimes necessary to swim only by the motion of both arms without using both legs for various purposes such as. For this purpose, a plate member (so-called "kick plate" or "pool buoy") made of synthetic resin having buoyancy has been swallowed. Fig. 1 is a schematic side view showing a state in which the kick plate 200 is sandwiched between legs.

However, in the case of the kick plate 200, the user easily gets out of the way in the process of swimming, and the user may be confused. In addition, since the kick plate 200 is sandwiched between the legs in a standing state, it is difficult to smoothly roll the swimmer in the lateral direction, and the swim using only the two arms can not be performed naturally.

The swinging motion of the arm in a swim is called a stroke, but an average stroke of 3,000 strokes is performed even if it swims for one hour (free-form basis). Swimmers (swimmers) practice resistance training as an aid to better swimming. Among the typical conventional resistance training, there is a pull operation using the stretching code as the ground training, which is training to develop the lobes and rotator muscles of the stroke, and to make an accurate pull operation posture.

Due to the nature of swimming, cyclic exercise should be used, so heavy resistance training is needed to prevent shoulder impingement syndrome (which is caused by excessive use of shoulder tendon and damage to the rotator cuff, and swimming players) in a short time. Long-term shoulder resistance training needs to be done. However, the kicking plate 200 shown in FIG. 1 can not effectively perform the above-described training required for swimming.

In addition to the conventional Korean Utility Model No. 20-0464187, various conventional swimming aids are intended only for buoyancy. When swimming with both arms as described above, they can concentrate on the operation of both arms. There has not yet been developed a swimming aid which can enhance the exercise effect by allowing the rolling to take place naturally while preventing the two legs from moving together and increasing the resistance of the water.

Korean Utility Model Registration No. 20-0464187 (December 14, 2012 notice).

The present invention has been developed in order to overcome the limitations of the prior art as described above. It is proposed to provide a swimming aid to be worn when swimming, in order to increase the momentum of both arms, For the various purposes such as grabbing and pushing backward, or for the purpose of correcting the movements of both arms, both legs should be worn on both ankles with both legs gathered so that both legs move The buoyancy is generated while the swimmer moves forward, and the swimmer causes a great resistance to water, thereby doubling the exercise effect and increasing the concentration of the arm motion, thereby maximizing the training effect of both arm movements. Further, So that it is possible to achieve a natural balance even with respect to the rolling of the roller.

In order to achieve the above object, in the present invention, a swimming auxiliary worn on a swim is composed of a ring-shaped buoyant body formed with a circular hollow in which a pair of ankles of a swimmer can be fitted, Both the ankles of the person are inserted into the hollow so that both legs are simultaneously clamped so that they can not move in a gathered state; The front face is orthogonal to the direction in which the front face swims to increase the resistance of the water when swimming forward, and it is possible to concentrate on the swimming motion of both arms.

In the above-described swimming aids of the present invention, dimples may be formed in concave grooves on either or both of the front surface and the rear surface, or alternatively. Concave grooves may be formed along the ring-shaped circumference on either the front surface or the rear surface or on either side of the two surfaces. In addition, in the above-described swimming assistant of the present invention, the swimming aid may be composed of a member filled with a hollow, or may be constituted by a tube member hollowed out and blown into a ring shape by blowing air.

If you swim by wearing a swimming aid according to the present invention, buoyancy is generated in the lower body, so that the swimmer can comfortably float on the water, but both legs can not move in the state of being gathered, so that they can concentrate on swimming in both arms. Therefore, the swimmer can use his arms and hands to efficiently swim the forward water and concentrate only on the arm movement that pushes backward, making it very useful for accurate correction and training of the swinging arm movements.

Particularly, when a swim is carried out by wearing the swimmer of the present invention, the front face of the swimmer is positioned orthogonally to the direction in which the swimmer is moving forward, and when the swimmer goes forward, . And the exercise effect can be doubled accordingly.

Furthermore, when the swim aids are worn by the swimmer of the present invention, it is easy to maintain the balance of the body while making the state of gathering the both legs naturally and at the same time, the swimmer's lateral direction The rolling motion can be performed naturally, and the advantage of being able to concentrate on both arms swimming comfortably.

In addition, when the swimming aid of the present invention is used, it is possible to perform the training to develop the lobar and the roots of the stroke, which are the main roots of the stroke, and the training to make the attitude of an accurate pull motion, naturally and effectively in the actual water And the exercise of balancing the body in the water can be performed very effectively.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its core structure and operation are not limited by this embodiment. In the present specification, a direction in which a swimmer (also referred to as a wearer) swims forward is referred to as " forward in the longitudinal direction "and a direction opposite thereto is referred to as a rear in the longitudinal direction.

FIG. 2 is a view of a swimming auxiliary tool 100 according to a first embodiment of the present invention, and FIG. 3 is a schematic partial perspective view showing a state in which the swimming auxiliary tool 100 of FIG. 2 is worn by a swimmer. 4 is a schematic side view showing a swimmer wearing and swimming the swimming aids 100 of FIG.

As shown in the drawing, the swimming aids 100 according to the present invention are composed of a ring-shaped buoyant body having a circular hollow 110 formed at the center thereof so that both ankles of the swimmer can be simultaneously inserted. That is, the swimming aid 100 of the present invention has a "circular" shape when viewed in the longitudinal direction, and is formed of a ring-shaped member having a hollow 110. In particular, in the present invention, the hollow 110 is formed in the center of the circle, so that the swimming aids 100 of the present invention are formed in a circular ring shape having a constant thickness and shape without being offset toward one side when viewed from the longitudinal direction . Accordingly, throughout the present specification including the claims, when the swimming aids 100 are viewed from the longitudinal direction, the swimming aids 100 are not displaced to one side, Is expressed as " the lateral shape is a circular ring shape ".

On the other hand, the swimming aid (100) of the present invention comprises a buoyant body that can float in water. For this purpose, the swimming aid 100 of the present invention can be made of a light synthetic resin, or it may have a configuration filled with the inside, or may have a configuration in which the inside is empty and the air is blown into the ring shape.

In particular, the swimming aid 100 of the present invention is made of a material having elasticity so that both ankles can be easily inserted into the hollow 110 while the two ankles are worn together. In addition, since the swimming aids 100 are wrapped around the ankles when the swimming aids 100 of the present invention are worn, the surface of the swimming aids 100 is preferably made of a soft material that is safe for the human body. For example, the swimming aids 100 can be manufactured using a material in which a soft fiber is coated on the surface of a synthetic resin.

5 to 6 are schematic half cross-sectional perspective views of the swimming aid 100 of the present invention taken along line A-A of FIG. 2, respectively. As shown in FIG. 5, the swimming assistant 100 may be made of a buoyant body filled with hollows, but it is formed of a tube member hollowed out as shown in FIG. 6, and when the wind is filled in the interior, It may have a configuration that flattenes out when the wind filled inside is removed. Therefore, when the swimming assistant 100 is manufactured in the form of a tube that blows up the air only when used in this way and blows out the air after use to reduce its volume, it can be carried conveniently, As shown in FIG.

When the swim assistant 100 having the above-described configuration is worn, both the ankles are inserted and inserted into the hollow 110 in a state where both legs of the swimmer are gathered so that the swim assistant 100 wraps both ankles do. That is, both the ankles of the swimmer are fitted in the hollow of the swimming aid 100. When you go forward from swimming, your legs will sink, your body will shake more and you will not progress by swimming. In order to prevent this, both of the ankles are inserted into one hole (hollow) in the swimming aid 100 of the present invention, so that both ankles are naturally collected. By this design, both legs of the swimmer are fixed together and the swimmer can not move both legs. Particularly, as shown in FIG. 4, when the swimmer swims while wearing the swimming aid 100 of the present invention, the swimming aid 100 floats on the water, And the front face of the swimming aid 100 is perpendicular to the axis of the swimmer's body in the longitudinal direction.

FIGS. 7 and 8 are photographs showing a swimming swim in which the swimmer wears the swimming aids of the present invention. FIGS. 9 and 10 are photographs showing a swimmer's ankle Is a photograph showing a state of being worn. Accordingly, as shown in FIGS. 4 and 7 to 10, the swimmer must swim with his / her body straight in the arm motion and move forward. At this time, the front face of the swimming aids 100 is rotated in a direction orthogonal to the swim direction, So that the front surface of the swimming aiding aid 100 can exhibit a large resistance force by colliding with water. That is, the swimmer must swim only by the arm forward in the longitudinal direction while overcoming the large resistance generated by the swimming aids 100. In FIG. 4, the arrow F indicates a state in which water flows by the swimming aid 100 when the swimmer wearing the swimming aid 100 of the present invention swims forward.

In this way, the swimmer must swim forward while swinging with the aid of the swimmer (100) of the present invention, so that the swimmer must swim in the back or swim in the body or put a simple simple kick plate on his leg and swim A very large exercise effect is exerted. In particular, the swimmer must move forward with his / her arm only, so that he or she can concentrate more on the operation of holding the water effectively using the arm and the hand and pushing it backward. Therefore, it is very effective in correcting and training to make precise arm motion necessary for swimming.

When swiming with both arms, both arms come into the water alternately and paddle, so that the swimmer moves in the direction of both sides in the transverse direction about the body axis. That is, as shown by the arrow R in FIG. 3, the body of the swimmer is moved about the body of the swimmer as it is reciprocating in the lateral direction. This motion is referred to herein as "rolling in the lateral direction ". The occurrence of this transverse rolling phenomenon occurs naturally in the swimming process, and if the transverse rolling is disturbed or obstructed, the swimming motion becomes very unnatural.

As shown in the figure, the swimming aid 100 according to the present invention is in a state in which it can freely rotate about a virtual rotation axis passing through the hollow 110 because the outer shape is a circular ring shape. Therefore, when the swimmer moves forward by swinging his / her arms in the state of wearing the swimming aid 100 according to the present invention, when the swimmer rotates, that is, in the lateral rolling, ) Will not interfere in any way with this lateral rolling, so that the swimmer will achieve a well-balanced and stable condition as the lateral rolling naturally takes place and the swimmer will be able to comfortably swim with both arms in this stable, You will be able to continue.

When swimming is performed by wearing the swimming aid 100 according to the present invention, both legs can not move in a gathered state, so that it is possible to concentrate on swimming with only two arms. Accordingly, So that it is very efficient to perform calibration and training to create the correct arm motion required for swimming.

In particular, since the swimming aid 100 of the present invention floats on the water by the buoyancy force, the user can easily float in the water while the body is stretched so that the user can swim comfortably.

In addition, when the swimmer 100 is worn by the swimmer 100, the front face of the swimminister 100 is positioned orthogonally to the swim direction. When the swimmer goes forward, ) Causes a large resistance to water. And thus the exercise effect can be doubled.

Above all, the present swimming aids 100 have a circular ring shape, so that it is possible to naturally allow rolling in the lateral direction, so that the lateral rolling motion of the swimmer, which occurs when swimming only with both arms, This makes it easier to balance the body, so you can concentrate on swimming with both arms comfortably.

Meanwhile, the swimming aids 100 according to the present invention can be manufactured in various types with different inner diameters of the hollows 110, for example, for children, adolescents and adults (men and women can be divided) according to the body sizes of male and female. That is, for a user having a small ankle such as a child or a woman, it is possible to manufacture the swimming aid 100 having a small-sized hollow 110. On the other hand, So that a swimming assistant 100 can be manufactured. In this way, when manufacturing the swimming aid 100 so that the size of the hollow 110 (hollow inner diameter) is changed according to the user, the outer diameter size of the ring shape may not be changed. However, The outer diameter of the ring 110 may be changed according to the outer diameter of the ring, so that the swimming support 100 may be manufactured. However, it is most preferable that the outer diameter of the circular ring shape in the swimming aid 100 according to the present invention has a size within a range of 200 mm or more and 360 mm or less. If the outer diameter of the circular ring in the swimming aid 100 is less than 200 mm, it will not function properly as a buoyant body and as an auxiliary device for training, while if it exceeds 360 mm, excessive resistance training will be performed The risk of a swimmer suffering from a shoulder injury is greatly increased. Therefore, it is preferable that the outer diameter of the circular ring shape in the swimming aid 100 has a value of 200 mm to 360 mm.

Fig. 11 shows a schematic perspective view of a swimming aid 100 according to a second embodiment of the present invention. Figs. 12 and 13 each show a schematic semi-sectional perspective view of the swimming aid 100 of the second embodiment taken along the line B-B of Fig. 9, respectively.

11 to 13, in the same manner as the first embodiment described above, a circular hollow 110 in which a pair of ankles of a swimmer can be inserted is formed at the center In addition, a dimple 120 having a concave groove shape like a crater is formed on either the front surface, the rear surface, or both surfaces. As shown in the drawing, the dimples 120 may be formed at a plurality of intervals along the circumference of the ring of the swimming aid 100, and may be formed on both the front and rear surfaces as shown in FIG. 12, 13 may be formed on only one of the front surface and the rear surface. Of course, when the dimples 120 are formed on only one side of the swimming aid 100, it is preferable to use the dimples 120 with the side on which the dimples 120 are formed facing forward.

In addition to the configuration in which the dimples 120 are formed in the swimming aid 100 and the arc-shaped configuration in the inside and outside of the swimming aid 100, in addition to the buoyancy member in which the swimming aid 100 is filled, The same can be applied to the case where the wind is swollen and filled in the inside to form a ring. When the swimmer 100 is worn so that the dimple 120 is positioned on the front surface of the swimming aids 100, the surface of the swim aids 100, So that the swimming load is further increased and the exercise effect is further enhanced. When the dimple 120 is formed on only one side, the swimmer may wear the swimming aid 100 so that the side on which the dimple 120 is formed faces forward or rearward as needed, . Other aspects of the swimming aids 100 according to the second embodiment shown in Figs. 11 to 13 are the same as those of the first embodiment, and therefore, a repetitive description thereof will be omitted.

14 to 16 are views of a swimming aid 100 according to a third embodiment of the present invention. FIG. 14 is a schematic perspective view of a swimming aid 100 according to a third embodiment of the present invention And FIGS. 15 and 16 show a schematic half cross-sectional perspective view of the swimming aid 100 of the third embodiment according to line CC of FIG. 14, respectively.

14 to 16, in the same manner as the first and second embodiments described above, a circular hollow 110 in which the ankles of the swimmer can be fitted is formed in the swimming aid 100 according to the third embodiment In addition, concave grooves 130 are formed along a ring-shaped circumference on either the front surface, the rear surface, or on either side of the two surfaces. As shown in FIG. 15, the ring-shaped concave groove 130 may be formed on both the front surface and the rear surface, but may be formed on only one of the front surface and the rear surface as shown in FIG. Of course, when the concave groove 130 is formed on only one side of the swimming aid 100, it is preferable to use the concave groove 130 so that the side on which the concave groove 130 is formed faces forward.

In the same manner as the second embodiment, in addition to the configuration added to the third embodiment, the concave groove 130 is formed of a tube member hollowed out, in addition to the case where the swimming aid 100 is made of a buoyant body filled with air, The present invention can be similarly applied to a case where a ring-like shape is formed. When the swimmer is worn so that the concave groove 130 faces forward, the swimmer moves forward and the swimmer moves to the swimming aids 100 The surface to be collided is further increased, so that the resistance force by wearing the swimming aid 100 is further increased, and the swimming load is further increased to further enhance the exercise effect. Other aspects of the swimming aids 100 according to the third embodiment shown in Figs. 14 to 16 are also the same as those of the first and second embodiments, and thus a repetitive description thereof will be omitted.

Although not shown in the drawing, as another embodiment of the swimming aid 100 according to the present invention, a dimple 120 is formed on one of the front surface and the rear surface, and the other surface is provided with a concave groove 130 ) May be formed. In the case where the dimple 120 is present, the resistance against water is greater than when the dimple 120 is not present. In the case where the concave groove 130 is formed rather than the dimple 120, the contact area with water is larger, Is also larger. Therefore, in the case of the swimming aid 100 having the dimple 120 on one side and the concave groove 130 on the other side, the swimmer can adjust the desired swimming face So that the user can wear the swimming aid 100. [

In the following, a verification test for the swimming aid 100 according to the present invention will be described.

The subjects of this experiment were 5 years or more of senior member of swimming pool of Ilsan - based swimming pool. The subjects of this experiment were swimming in Ilsan, Gyeonggi - do (six 25 - meter length lanes, 25-27 degrees Celsius and 25 degrees Celsius) An adult male (30 years old / height 175 cm / weight 67 kg) was used. To verify the maximum reference range of buoyancy and resistance, the male test subjects were subjected to a verification test in order to determine the maximum range of buoyancy and resistance because the male had lower buoyancy and better strength of the shoulder muscle than the female.

As a first test item, in order to ascertain the degree of functioning as a buoyant body without sinking into water according to the change in outer diameter size of the swimming aids 100 according to the present invention, It was observed whether or not the subject could hold the water in the horizontal posture in the state where the swimming aid 100 having the respective outer diameters was sandwiched between the ankles of the subject while gradually reducing the outer diameter.

As a second test item, in order to confirm the effect of the present invention on the shoulder of the subject due to the difference in resistance according to the change in the outer diameter of the swimming aid 100, The subject felt a shoulder pain when the subject swim freestyle for one hour at intervals of one day while wearing the swimming aid 100 of the present invention while gradually increasing the outer diameter of the subject 100.

According to the test results, when the outer diameter of the swimming aids 100 is less than 200 mm, the specific gravity of the swimming aids 100 itself becomes higher than the specific gravity of the water, failing to function as a buoyant body, The subject wearing the swimming aids (100) on both ankles failed to maintain the horizontal posture in the water. On the other hand, when the outer diameter of the swimming assistant tool 100 is 200 mm or more, there is no problem in maintaining the horizontal turning posture.

On the other hand, according to the pain check test, if the outer diameter of the swimming aid 100 exceeds 360 mm, the subject complained shoulder pain within about 30 minutes from the start of swimming.

Based on these test results, the hollow inner diameter of the swimming aid 100 has a size that can be brought into close contact with the ankles of the swimmer, while the outer diameter of the circular ring of the swimming aid 100 has a value of 200 mm to 360 mm As shown in Fig.

For comparative testing with other types of swimming aids, the above subjects were tested under the same conditions with a conventional kick board and pool buoy worn. FIG. 17 is a drawing showing a conventional kick board used for a comparative test with a swimming aid of the present invention; FIG. FIG. 18 is a photograph showing a conventional pull part used for a comparative test with a swimming aid of the present invention; FIG.

The comparison test with the other swimming aids was also carried out in a swimming pool (25 meters long, lane 25 ~ 27 degrees Celsius, water temperature 27 ~ 29 degrees Celsius) in Ilsan, Gyeonggi Province. The average age of the subjects was 27 years old and 43 years old. The average age was 35 years old. The subjects scrolled freely without wearing any of the swimming aids or other swimming aids of the present invention and recorded SC for each of them. The swimming aids of the present invention were subsequently worn on the ankles. Figs. 17 and 18 Of the swimming aids swim freely between the legs of the subjects under their hips and recorded their respective SCs. For reference, the stroke count (SC) means the number of strokes when swimming.

When swimming 100m freestyle at 70% of full speed, 50m freestyle SC of 50 ~ 100m interval was confirmed for each of swimming aids and other swimming aids.

Table 1 summarizes the comparative test results of the swimming aids and other swimming aids of the present invention.

In this experiment, the SC when swimming 50 m freestyle without swimming aids and the SC when swiming 50 m freestyle with a kick board and a swimming pool showed little difference, but according to the present invention The SC when swiming 50m freestyle with swimming aids showed a big difference. This clearly confirms that the swimming aids of the present invention are capable of exhibiting greater water resistance than kickboards and pool buoys, as well as buoyancy, and are therefore highly effective for swimming training.
