Description

{Swimming aids for breaststroke}

The present invention relates to a swimming aid for breaststroke, and more particularly, to a swimming aid for breaststroke worn by a swimmer to assist in breaststroke practice.

Among the commonly used swimming methods, breaststroke is a stroke in which the swimmer moves forward by repeatedly closing and extending both arms and legs like a frog by being level with the surface of the water. Most inflexible ordinary people find it difficult to learn.

Therefore, when practicing and learning breaststroke, it is necessary to correct the posture through a professional instructor. At this time, the swimmers have a high dependence on the instructor for physical guidance. There is a problem that long-term skills are fixed.

In addition, while the instructor guides the swimmers individually, the instructor's wrist injury often occurs, and if the instructor does not receive guidance, there is a concern that the swimmer loses interest in breaststroke practice and leaves.

On the other hand, as a prior art to solve this problem, Korean Patent Registration No. 10-2124918 discloses "breaststroke training device for survival swimming", but in the prior art, a swimmer sits on the exercise device indoors, not in the water. Since breaststroke is practiced by doing so, there is a problem that practical breaststroke practice is difficult because it is difficult to come out of the practiced breaststroke posture in actual swimming situations.

On the other hand, existing swimming flippers exist to assist and improve swimmers' swimming skills, as their fins are located in front of their toes, so they can only be used in freestyle, backstroke, and butterfly strokes where the instep pushes the water. There are no fins for breaststroke where the fins are located on the inside of the feet.

The present invention relates to a swimming aid for breaststroke that is worn by a swimmer to assist in breaststroke practice, and the fins (1) are provided on one side of the wearer (100) and a wearer (100) directly worn on the swimmer's feet. It is composed of a wing portion 200 to be.

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

The wearing part 100 has a cylindrical shape into which a swimmer's foot can be inserted, and has a front open hole 101 through which the swimmer's toes can protrude outward, and both sides of the open rear surface. Hangers 110 connected to each other are formed.

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

An upper surface opening hole 102 centered on the hanger 110, in which the swimmer's foot is inserted and the ankle is located inside when worn, and the user's heel at the lower rear centered on the hanger 110. A rear open hole 103 is formed by protruding outwardly and into which it is inserted.

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

In addition, the wearing part 100 has a shape that covers the top of the foot and the sole of the foot except for the heel and toe, and water flowing into the wearing part 100 easily flows toward the front opening hole 101 and the rear opening hole 103 during swimming. It can be slipped out, so it can provide a light and convenient fit to the user.

On the other hand, the wearable part 100 has an effect that the swimmer can easily walk even while moving after finishing swimming practice. When walking, water accumulated inside the wearable part 100 during swimming reduces the wearer's wearing comfort or moves the swimmer. In the process, there is a problem that the water accumulated in the front opening hole 101 or the rear opening hole 103 may flow out and create a puddle.

In particular, since the sole of the foot is not generally flat and has a curve formed on the inside, it is easy for water to move in a state of accumulation in the gap 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, there are a plurality of drain holes 120 so that the water remaining inside the wearing part 100 that has not been discharged to the front opening hole 101 or the rear opening hole 103 can easily escape. ) may be additionally formed.

The drain hole 120 is formed through the lower surface of the wearing part 100, and allows water remaining inside the wearing part 100 to be easily discharged out of the flippers 1 and toward the ground.

The drain hole 120 is formed on the lower surface of the wearable part 100, especially on the side where the swimmer wears the flipper 1 and then steps on the ground by being in close contact with the sole of the foot. It can provide a comfortable fit to the swimmer by quickly discharging water accumulated in the space between the liver.

In addition, the swimmer can easily walk on the ground while wearing the flippers 1. As will be described later, the flippers 1 are made of silicon, so they can easily adhere to the swimmer's feet, but they can easily adhere to the ground, especially the bottom of the pool. In the case of a tile, it is difficult to come into close contact with the lower surface of the wearable part 100, and there is a risk that a swimmer wearing the tile 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 wearing part 100 to improve the frictional force between the lower surface of the wearing part 100 and the ground, thereby preventing the swimmer from slipping while walking. .

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

The wing part 200 is provided on one side of the wearable part 100, that is, on the inner side of the swimmer's foot, and serves to assist the swimmer wearing the flippers 1 in performing breaststroke by generating resistance on the inner side of the foot during breaststroke. . These wing parts 200 perform the same role as fins.

In particular, when performing breaststroke, kicking is performed while feeling the resistance of water on the inner skin of the foot on the side of the peach bone. The wings 200 together with the sole of the swimmer improve resistance to water, enabling breaststroke to be performed more easily. It plays the role of assisting to push a lot of water and go far.

The wing portion 200 includes an extension surface 210 protruding inward of the foot from one side of the wearable part 100 and a curved surface 220 extending upward by being bent from the protruding surface of the extension surface 210. includes

The extension surface 210 separates the curved surface 220 from one side of the wearing part 100 to form a space on the inside. ) side to prevent the generation of resistance from being reduced, and during breaststroke, water colliding with the wings 200 flows into the gap between the wearable part 100 formed through the expansion surface 210 and the curved surface 220 to further It allows for large amounts of water to be pushed out.

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

In addition, the expansion surface 210 protrudes from one side of the wearing part 100, but the upper surface of the expansion surface 210 is depressed downward to form a bend, so that a greater amount of water flows through 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 and extended. 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 so that a large amount of water to be able to push

In addition, the curved surface 220 improves the frictional force generated during collision by increasing the impact surface that collides with water with the feet of the swimmer wearing the wearable part 100 when the swimmer performs breaststroke and kicks. can perform breaststroke.

In particular, since the curved surface 220 is bent upward and extended, even if the swimmer walks on the ground after wearing the flippers 1, the wings 200 do not affect the swimmer's stride length and walking, so the flippers 1 are easily worn. to be able to walk afterward.

A streamlined inclined surface 221 having an inclination is formed on the front side of the edge of the curved surface 220 as the width extending upward increases rapidly toward the rear side.

The streamlined inclined surface 221 is formed at the front side 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 extension surface 210 is gradually upward toward the rear. It is generated by increasing the height extended to .

After wearing the flippers (1), the swimmer first splits the water with the tip of the toe protruding through the front opening hole 101 during breaststroke, so if excessive friction with the water occurs, the swimmer has a problem that it is difficult to stretch out the foot and split the water. .

Therefore, the front side of the curved surface 220, which first cuts the water with the swimmer's toe, is formed to correspond to the frontal height of the extended surface 210, but gradually extends upward toward the rear side to form a streamlined inclined surface 221. This solves the above-described problem, and allows water to more easily flow into the space separated between the wearing part 100 and the wing part 200 to push out a large amount of water so that it can move forward easily.

At this time, the curved surface 220 including the streamline 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 wireline inclined surface 221 It is preferable that the front side of is provided at a position corresponding to the bottom surface of the wearing part 100 and the height changes rapidly toward the rear side to form an inclination.

The above-described fins 1 are most preferably made of silicon, but are not limited thereto, and are made of a material that has a waterproof function and does not deteriorate due to moisture even when used frequently.

In particular, it is made of a light and flexible material, so it can accommodate various foot sizes, and has an effect of making swimming and walking comfortable due to a light fit when worn.

Therefore, water resistance required for breaststroke is improved through the wing part 200 having the above-described configuration so that a swimmer can practice breaststroke by himself, and the space between the wearing part 100 and the wing part 200 is spaced apart. As a result, a large amount of water flows in and pushes out a larger amount of water so that it can move forward.

In addition, since the wings 200 are bent and extended upward rather than in an unfolded state, water accumulated inside the wearing part 100 easily escapes without affecting walking and stride length, and the lower surface of the wearing part 100 It can also prevent slipping while walking by improving friction.
