Description

  The present invention is proposed for a practice paddle that is worn on the hand during swimming strokes, mainly for strengthening the strength of the upper body and arms, and for training the sense of balance of the stroke. It relates to paddles that are easy to relax.

Among the swimming exercise equipment, the paddle increases its strength by applying water pressure to the catch, pull, push, and finish movement processes during the stroke. Since it has the advantage of developing a sense of balance between strokes and strokes, it is used in practice in pools.
Practical swimming practice tools for strokes include paddles, gloves, and fins, but in any case, the device must be worn on the hand so that it can effectively gain propulsive force by arm movement or palm movement during the stroke. Are different, and each paddle, fin, and glove has its own wearing method.
The front of the paddle (the side where the water hits at a right angle) may be flat or slightly curved inside. Generally, a rubber tube is attached to this and a wrist or middle finger is passed through. Also, some gloves and fins are worn with hands and webbed between fingers. In order to strengthen the arm strength, it was practically sufficient for a swimming exercise tool such as a paddle to apply a load so that the resistance of water is as large as possible.

In the conventional paddle, a rubber tube is used as a means for binding the wrist or the middle finger to attach the wrist and the middle finger to the paddle. This is because the wrist and middle finger are in close contact with the back side of the paddle plate surface due to the elasticity of the rubber tube, which makes the blood flow of the palm worse and the sense of balance worsens, making it easier to get tired and freeing the palm. It cannot be said that the relaxation effect caused by the above can be fully demonstrated. For this reason, when the paddle is attached with a rubber tube, the right and left balance of the paddle is not good and an effective stroke cannot be obtained, which causes fatigue.
In addition, since fins and gloves have webbed between fingers, in order to feel the extra water pressure hitting this, it is different from the sense of balance of the body that actually swims due to the extra water pressure on the palm and arm. In such an unbalanced state, there was a problem of practicing winning with the main purpose of improving strength. Conventional practice tools such as paddles, gloves, and fins have a drawback that it is difficult to acquire a sense of balance of delicate strokes of the whole body swimming underwater.

  In applications where paddles are used to increase muscle strength and develop a sense of balance in swimming strokes, this drawback is a major obstacle to exerting sufficient ability in swimming competitions. Specifically, unnecessary muscle strength is strengthened, so it is possible to swim with unnatural strokes, a sense of continuity with a good balance between left and right strokes in actual swimming, or swimming palms are paddles Water pressure is received by the board surface and fin film, causing the foam to collapse during swimming. For this reason, there is a problem that the state of swimming with the correct stroke is forgotten. In order to solve this problem, it is necessary to acquire not only muscular strength but also a sense of balance when practicing strokes.

As a measure to improve this, use a method with a slight curve on the front of the paddle, or use it by making a hole in the paddle, and approximating the sense of water that hits the paddle to receive the water pressure that actually swims on the palm. There is. Patent Document 1 will be described as an example showing the form of a paddle according to this method, and has a slightly curved surface with respect to the direction in which water hits the paddle (FIGS. 3 and 4 of Cited Document 1). However, even with this method, it is difficult to make the palm receive the same water pressure during the left / right stroke in swimming. Further, the hand attached to the paddle tends to get tired because the periphery of the middle finger is tightened by the fastening member 6 (quoting the reference numeral cited) and the palm is in close contact with the paddle, resulting in poor blood flow. It is clear from the catalog distributed by the applicant of Patent Document 1 that the fastening member is a rubber tube.
Also, the webbed attached to swimming gloves (Patent Documents 2 and 3) and swimming aids (Patent Document 4) itself receives a lot of water pressure between the fingers, as opposed to the palm where humans swim. However, when you actually swim with bare hands, you will not be able to swim with a good balance of left and right strokes. This is because the palm of the swim is lightly closed between the fingers, which has nothing to do with the web for spreading the water between the fingers and spreading the water between them.

The problem to be solved by the present invention is that the wrist is attached to the back of the paddle with a string that hangs on the thumb and forefinger, the ring finger and the little finger, so that the wrist wearing the paddle is free and the middle finger and palm of the hand are always attached. It is intended to be relaxing. As explained in the background art, when the wrist or middle finger is fixed to the back of the paddle by contraction of the rubber tube attached to the paddle when practicing swimming, the rubber tube tightens the blood vessel passing through the wrist or middle finger, so that the blood is contracted. The flow becomes worse and it becomes an obstacle to watering with a paddle using a palm. For this reason, the water pressure received in front of the paddle cannot be balanced because the sensation of water in front of the paddle cannot be sufficiently confirmed by the sense of water hitting the palm.
By freeing the wrist wearing the paddle, which is the problem to be solved by the present invention, and allowing the middle finger and palm of the hand to be relaxed at all times, this swimming exercise device applies a load in the stroke to improve the strength of the arm. In addition to strengthening, it is possible to cultivate a sense of adjusting the direction of water pressure and the left-right balance when the arm or hand catches water when water is drained.

  The present invention attaches a hand to a paddle using a string as a wearing means for always freeing the wrist or middle finger to relax the palm, and puts the thumb and index finger, and the ring finger and little finger on the back of the paddle The main feature is that the palm and the middle finger are put on the back of the paddle so that the wrist and middle finger can be relaxed.

  Since the paddle for swimming practice of the present invention can be relaxed because it is passed through the string 2a for applying the thumb and forefinger, and the string 2b for applying the ring finger and the little finger, so that it can be relaxed. There is an advantage that the blood flow of the palm is improved and a sense of balance between right and left can be given according to the water pressure condition and the direction of force in each process of catching, pulling, pushing and finishing the stroke.

  Without tightening the base of the wrist and middle finger, that is, improve the blood flow of the attached palm, the balance of right and left depending on the water pressure conditions and the direction of force in each process of stroke catch, pull, push, finish The purpose of practicing was achieved by wearing a string without compromising the paddle's strength-improving effect.

  FIG. 1 is a front view of an embodiment of the paddle according to the present invention. 1 is a paddle body, 2a and 2b are strings, 3a and 3b are string movement stop holes, 3c and 3d are string passing holes, 4a and 4b are string through holes, 5 is a water pressure adjusting hole, and 6 and 7 are strings on the front of the paddle.

  The strings 2a and 2b always pass through the thumb and forefinger and ring finger and little finger, and the middle finger is free so that the swimmer's palm can be relaxed by the paddle direction and left / right balance. Since the subject of the present invention is a paddle mounting method that does not tighten the wrist or fingers, description of the paddle shape is omitted.

  On the plate surface of the paddle body, there are provided through holes 3c, 4a of a string 2a through which a palm index finger and thumb are passed, and through holes 3d, 4b of a string 2b through which a ring finger and little finger are passed. In order to prevent the ends of the strings 2a and 2b from coming out of the strings through holes 3c and 3d, string movement stop holes 3a and 3b were provided to pass the ends of the strings. One string 2a, 2b having low stretchability is passed through the above-described string through holes 3c, 4a, 3d, 4b provided in the paddle, and both ends of the string are passed through the string movement stop holes 3a, 3b. When wearing, the thumb and forefinger are passed through the string 2a, the ring finger and the little finger are passed through the string 2b, and the middle finger is freed.

  The paddle for swimming practice that relaxes the palm of the embodiment has a water pressure adjusting hole 5 between the index finger and the thumb to balance the water pressure that hits the paddle body. It works to get closer to. .

  One string 2a, 2b having low stretchability is preferably a fiber string, and a material that expands and contracts like a rubber tube becomes a factor that impedes blood flow of the palm.

  The fiber string material is a string formed by twisting synthetic resin fibers or plant fibers.

  What can replace the textile string may be a knitted string made of synthetic resin fibers or plant fibers.

  Since the string is adopted as a method of attaching the paddle, there is no deterioration of the string due to the water quality of the pool, and even if the paddle is attached, the palm can be relaxed without tightening the blood vessel through which blood flows. Therefore, the swimmer can maintain the blood flow by relaxing the palm. The water pressure adjustment hole 5 makes the water pressure close to the feeling of swimming with bare hands, making it easier to balance the left and right strokes. Furthermore, it is easy to turn the front of the paddle in the direction in which the force enters, and the swimmer has the effect of cultivating a sense of balance without getting tired even when practicing to increase strength.

  In the embodiment, when practicing with a swimming paddle that can relax the palm, in order to prevent fatigue due to load, it is necessary to relax the palm. It is very useful for improving the operability and practice effect.

  By opening a hydraulic pressure adjustment hole to make it easier to balance the paddle between the thumb and forefinger on the string attached to the paddle body by easily relaxing through the thumb and forefinger, ring finger and little finger, not only improving muscle strength, It can be used for stroke practice where a sense of balance between the right and left by the swimmer is required and a sense of balance between the left and right is essential.
