Description

Swimming assist device{SWIMMING ASSISTANCE APPARATUS}

The present invention relates to a swimming aid device. More specifically, it relates to a swimming assisting device that assists the user to provide buoyancy to a part of the user's body underwater to correct a swimming posture or to concentrate on strengthening upper body and lower back muscles.

Swimming is one of the body exercises that strengthens lung capacity and endurance and strengthens the whole body. Therefore, swimming is attracting attention as a daily sport in the world, including Korea, the United States, Australia, Japan, and China.

Conventional swimming aids include a tube, a buoy, and a board. The tube is constructed in the form of a donut. The user may wear the tube so that it wraps around the waist, or it may be worn to support the user's upper body by wrapping one side of the tube with his or her hand. Bugu is constructed in the form of a sphere with a handle. The user is assisted with buoyancy by holding the handle of the buoy. The board is constructed in the form of a plate. The user grabs the board and receives buoyancy assistance.

However, conventional swimming aids such as tubes, buoys, and boards must be held by the user when swimming. Therefore, it hinders the user's arm movement as a whole. Accordingly, the user cannot completely perform the swimming posture as long as the conventional swimming assist device is used.

In addition, since the conventional swimming assist device is easily separated from the user's hand, a beginner who cannot swim at all may miss the conventional swimming assist device from the hand. For beginners in swimming, this experience provides a feeling of reluctance or rejection to the water, leaving it as a trauma in the beginner's head for a long time.

In addition, when using a conventional swimming aid, there is a problem that the user must always strain the muscles of the arm. As a result, the user is easily exhausted, and thus does not gain confidence in swimming. Also, because the muscles are tense, it becomes difficult to smoothly correct the swimming posture.

In addition, in the case of a bugu and a board among conventional swimming aids, there is a problem in that only the lower body excluding the upper body can be trained. This is because the user holds the board with both hands and extends both arms and body straight and moves forward by the kicking motion.

In addition, in the case of a vest-type bugu among the conventional swimming aids, there is a problem in that the swimming method is limited and it is difficult for the user to hold a posture underwater. This is because the vest-shaped buoy allows the user to float vertically in the water.

In addition, the swimming method that can be realized when using a conventional swimming aid is quite limited. In general, when a conventional swimming aid is used, only the swimming method of swimming by moving the waist up and down may be possible. Such a stroke can further aggravate lower back pain in patients who complain of lower back pain with a herniated disc.

In addition, in the case of disabled people such as lower extremity paralysis, it is impossible to kick or swim by moving the waist up and down. Therefore, the disabled people with lower extremities could not use the conventional swimming aids.

Therefore, the present invention was devised to improve the problems presented above.

According to the eleventh embodiment of the present invention, the swimming assisting device 1 provided with the separation preventing means has the effect of fixing the swimming assisting device 1 to the user's leg according to the user's selection.

Mode of use of swimming aids

With respect to the use aspect of the swimming assist device 1, the swimming assist device 1 according to an embodiment of the present invention is provided in the insertion hole 20 through the cutout 30 of the swimming assist device 1 Both legs are inserted and worn. It is fixed in a state in which both legs of the user are gathered by the swimming aid 1. The user may wear the swimming aid 1 on the calf, knee, thigh, etc., and in a more preferred embodiment, it may be worn on the ankle.

The user trains various strokes while moving the waist from side to side or stirring the arm while the leg is fixed using the swimming aid (1). In water, the swimming aid 1 floats the user's lower body due to buoyancy. This allows the user to configure various strokes without paying attention to the lower body. The user can move forward with a stroke that flows alternately with the user's waist to the left and right, respectively. This is the same way that fish swim using the tail fin. With such a stroke, the user's upper body and lower back muscles are strengthened, as well as the effect of correcting the user's distorted pelvis.

According to the swimming aid device 1 according to an embodiment of the present invention, since it is possible to swim with only the movement of the upper body without kicking, swimming is also possible for disabled people with lower body paralysis who cannot move the lower body at all, children with weak lower body strength, and the elderly. There is an effect that becomes possible.

As described above, those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are illustrative in all respects and should be understood as non-limiting. The scope of the present invention is indicated by the claims to be described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the claims and equivalent concepts should be interpreted as being included in the scope of the present invention.
