Description

Breaststroke Training Flippers {BREASTSTROKE TRAINING FLIPPERS}

The present invention relates to flippers for breaststroke training, and more particularly, to flippers for breaststroke training worn by swimmers to assist breaststroke practice.

Among the commonly used swimming methods, the breaststroke is a stroke in which the swimmer moves forward by repeatedly closing and extending the arms and legs like a frog, level with the water surface. Most ordinary people who are not flexible have a hard time learning.

Therefore, when practicing and learning breaststroke, it is necessary to correct the posture through a professional instructor. There is a problem that skills are fixed for a long time.

In addition, there is a concern that the instructor's wrist injury frequently occurs in the process of coaching swimmers individually, and swimmers lose interest in breaststroke practice and leave if they do not receive instruction.

On the other hand, as a prior art for solving this problem, Korean Patent Publication No. 10-2124918 discloses "a breaststroke practice device for survival swimming", but the prior art is that a swimmer sits on the practice device indoors, not in water. Therefore, there is a problem that breaststroke practice is difficult because the practiced breaststroke posture is difficult to obtain in an actual swimming situation because breaststroke is being practiced.

On the other hand, the existing swimming flippers that exist to assist and improve swimmers' swimming skills are mainly used in freestyle, backstroke, and butterfly swimming by pressing the water with the instep because the fins are located in front of the toes. There are no flippers with fins on the inside of the feet for breaststroke.

The present invention relates to flippers for breaststroke training worn by swimmers to assist in breaststroke practice. These flippers (1) include a wearing part 100 that is directly worn on a swimmer's feet, and a wing provided on one side of the wearing part 100. It consists of part 200 .

The wearing part 100 is capable of accommodating the foot by wrapping the ball and back of the swimmer's foot, and corresponds to the part directly worn when the swimmer wears the flippers 1 .

This wearing part 100 is made of a cylindrical shape into which a swimmer's feet can be inserted, a front opening hole 101 is formed through which the swimmer's toes, etc. can protrude outward, and both sides of the open rear surface are formed. A hook 110 that is connected to each other is formed.

The hook 110 is a part caught on the Achilles tendon or ankle side of the swimmer, and it can prevent the wearing part 100 from peeling off from the foot when the swimmer swims or moves while wearing the flippers 1 .

The upper surface opening hole 102 in which a swimmer puts their feet on the upper side with the hook 110 as the center and the ankle is located on the inside when worn, and the lower rear of the user's heel around the hook 110 . A rear opening hole 103 is formed to protrude outward and fit.

Therefore, through the hook 110, the front open hole 101, the upper surface open hole 102, and the rear open hole 103, the swimmer can easily put their feet into the wearing part 100 and wear it, Since the ball 110 is hooked and fixed on the back side of the foot, that is, on the side where the Achilles tendon or the ankle is located, it is possible to prevent the swimmer's foot from being separated from the flippers 1 during breaststroke practice or during movement.

In addition, the wearing part 100 has a shape that covers the back of the foot and the sole of the foot except for the heel and toes, and when swimming, water flowing into the wearing part 100 inside the front opening hole 101 and the rear opening hole 103 side is easily It can be pulled out to provide a light and comfortable fit to the user.

On the other hand, the wearing unit 100 has the effect that the swimmer can walk easily even in the process of moving after completing swimming practice. In the process, there is a problem that stagnant water flows out toward the front open hole 101 or the rear open hole 103 to create a puddle.

In particular, since the sole of the foot is not generally flat but curved on the inside, it is easy to move in a stagnant state between the arch-shaped curve formed on the sole of the swimmer and the inner lower surface of the wearing part 100 .

Therefore, on the lower surface of the wearing part 100, a plurality of drain holes 120 so that the water remaining inside the wearing part 100 that has not been discharged to the front open hole 101 or the rear open hole 103 side can easily escape. ) may be further formed.

The drain hole 120 is formed through the lower surface of the wearing part 100 so that the water remaining inside the wearing part 100 can be easily discharged to the outside of the flippers 1 and to the ground side.

Such a drain hole 120 is formed on the lower surface of the wearing part 100, especially on the side where the swimmer puts on the flippers 1 and then touches the sole of the foot and steps on the ground, and the inner lower surface of the wearing part 100 and the sole of the swimmer's feet It can provide a comfortable fit for swimmers by quickly discharging water that accumulates in the liver space.

In addition, a swimmer can easily walk on the ground while wearing the flippers 1, as described later, since the flippers 1 are made of a silicone material, they can be easily attached to the swimmer's feet, but on the ground, especially the bottom of the swimming pool. In the case of the tile, it is difficult to adhere to the lower surface of the wearing part 100 , so there is a risk that the swimmer wearing it may slip while walking due to the flippers 1 .

Therefore, as shown in FIG. 9 , a friction surface 130 is formed on the outer lower surface of the wearable part 100 to improve the frictional force between the lower surface of the wearable part 100 and the ground, thereby preventing the swimmer from slipping while walking. .

The friction surface 130 corresponds to the bottom surface in close contact with the ground when the swimmer steps on the ground after wearing the flippers 1, and a plurality of friction grooves are formed along the friction surface 130 in a comb pattern. Friction can be improved, and a swimmer wearing flippers 1 can safely walk even on a slippery surface of a swimming pool tile.

The wing unit 200 is provided on one side of the wearing unit 100, that is, inside the swimmer's foot, and the swimmer wearing the flippers 1 generates resistance on the inside of the foot during breaststroke to assist in breaststroke performance. . These wing parts 200 perform the same role as fins.

In particular, when performing breaststroke, the kick is performed while feeling the resistance of water on the inner skin of the foot on the side of the peach bone. The wing part 200 along with the swimmer's sole improves resistance to water, allowing the breaststroke to be performed more easily, and more easily during breaststroke. It pushes a lot of water and plays a role in assisting it to go far.

The wing part 200 has an extended surface 210 protruding in the inner direction of the foot from one side of the wearing part 100 and a curved surface 220 extending by bending upward from the protruding surface of the extended surface 210 . includes

The extended surface 210 forms a space inside the curved surface 220 and one side of the wearing part 100 by spacing them apart. ) side to prevent lowering of the resistance, and water that collides with the wing 200 during breaststroke flows into the gap between the worn part 100 and the curved surface 220 formed through the extended surface 210, further Allows for a large amount of water to be expelled.

At this time, the thickness of the extended surface 210 is formed to be thicker than the thickness of the curved surface 220, and is made of hard silicon so that the curved surface 220 can be supported to maintain an extended state by bending upward.

In addition, the extended surface 210 protrudes from one side of the wearable part 100 , but the upper surface of the extended surface 210 is depressed downward to form a curved shape, so that a larger amount of water is absorbed by the wearing part 100 and the wing part 200 . Allow it to flow into the spaced space between the liver (see FIG. 3).

The curved surface 220 is connected to the protruding end of the extended surface 210 and is bent upward to extend. As shown in FIG. 5 , the curved surface 220 has a shape corresponding to the side surface of the wearing part 100 and maximizes the inner space formed in the gap between the wearing part 100 and the wing part 200 to increase the amount of water. to be able to push

In addition, the curved surface 220 increases the collision surface that collides with the water together with the swimmer's foot wearing the wearing part 100 when the swimmer performs breaststroke and kicks, thereby improving the frictional force generated during collision. Able to perform breaststroke comfortably.

In particular, since the curved surface 220 is curved upward and extends upward, even if the swimmer walks on the ground after wearing the flippers 1, the wing part 200 does not affect the swimmer's stride length and gait, so that the flippers 1 are easily worn. then be able to walk.

On the front of the edges of the curved surface 220 , the width extending upward is sharply improved toward the rear to form a streamlined inclined surface 221 having an inclination.

The streamlined inclined surface 221 is formed at the front edge of the curved surface 220 provided with the front opening hole 101, and the curved surface 220 connected to the protruding end of the extended surface 210 gradually upward toward the rear. It is caused by an increase in the extended height.

Since the swimmer first cuts the current with the tip of the foot protruding through the front opening hole 101 during breaststroke after wearing the flippers (1), there is a problem that it is difficult for the swimmer to stretch out their feet and split the water if the frictional force with the water is excessive. .

Therefore, the front side of the curved surface 220 that separates the water together with the swimmer's toes is formed to correspond to the front height of the extended surface 210, and gradually extends upward toward the rear to form a streamlined inclined surface 221. Thus, the above-described problem is solved, and water is more easily introduced into the spaced apart space between the wearing part 100 and the wing part 200, and a large amount of water is pushed out so that the user can easily advance.

At this time, the curved surface 220 including the streamlined inclined surface 221 is formed along the side end of one side of the wearing part 100, and the height extending upward gradually increases from the front to the rear, but the streamlined inclined surface 221 It is preferable that the front side of the is provided at a position corresponding to the bottom surface of the wearing part 100, and the height changes rapidly toward the rear so that an inclination is formed.

The flippers 1 described above are most preferably made of a silicone material, but are not limited thereto, and are made of a material that does not change due to moisture even when used frequently due to a waterproof function.

In particular, it is made of a light and elastic material, so it can accommodate various foot sizes, and has the effect of being comfortable for swimming and walking due to its light fit when worn.

Therefore, through the wing unit 200 having the above-described configuration, the inner foot water resistance required for breaststroke is improved, so that even a swimmer can practice breaststroke, and a spaced space between the wearing unit 100 and the wing unit 200 . This allows a large amount of water to flow in and pushes out a larger amount of water, allowing it to move forward.

In addition, the wing part 200 is bent upward instead of in an unfolded state, so that it does not affect walking and stride length, and allows water accumulated inside the wearing part 100 to easily escape, and the lower surface of the wearing part 100 It can also prevent slipping while walking by improving friction.
