Description

Swimming assistance device {SWIMMING ASSISTANCE APPARATUS}

The present invention relates to a swimming assistance device. More specifically, it relates to a swimming assistance device that provides buoyancy to a part of the user's body underwater and assists the user in correctly correcting swimming posture or focusing on strengthening upper body and back muscles.

Swimming is one of the full-body exercises that strengthens lung capacity and endurance and strengthens the entire body. Therefore, swimming is in the spotlight as a lifestyle sport around the world, including in Korea, the United States, Australia, Japan, and China.

Conventional swimming assistance devices include tubes, floats, boards, etc. The tube is constructed in a donut shape. The user can wear the tube so that it wraps around their waist, or they can wear it by wrapping one side of the tube with their hand to support the user's upper body.

However, conventional swimming aids such as tubes, floats, and boards require users to hold them with their hands while swimming. Therefore, the overall movement of the user's arm is hindered. As a result, the user cannot perfectly perform the swimming posture when using a conventional swimming assistance device.

In addition, the conventional swimming aid device easily falls out of the user's hand, so beginners who cannot swim at all may lose the conventional swimming aid device. For beginner swimmers, this experience provides a feeling of avoidance or rejection of water, which remains as a long-term trauma in the beginner's mind.

Additionally, when using a conventional swimming assistance device, there is a problem in that the user must always tense the arm muscles. As a result, the user gets tired easily and does not gain confidence in swimming. Additionally, because the muscles are tense, it becomes difficult to smoothly correct the swimming posture.

In addition, in the case of floats and boards among conventional swimming assistance devices, there is a problem that only the lower body can be trained, excluding the upper body. This is because the user holds the float and board with both hands, straightens both arms and body, and moves forward through a kicking motion.

In addition, in the case of vest-type floatation among conventional swimming assistance devices, there are limitations in swimming method and it is difficult for the user to maintain a posture in the water. This is because the vest-type float allows the user to float vertically in the water.

Additionally, the swimming methods that can be realized when using conventional swimming assistance devices are significantly limited. In general, using a conventional swimming aid device, only the swimming stroke that involves moving the waist up and down is possible. This stroke can further aggravate back pain in patients who complain of back pain due to lumbar disc problems.

Additionally, in the case of people with lower limb disabilities such as paraplegia, it is impossible to kick or move the waist up and down to swim. Therefore, people with lower extremity disabilities were unable to use conventional swimming assistance devices.

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

The purpose of the present invention is to cover a part of the user's lower body, such as the calf or ankle, to provide buoyancy to a part of the user's lower body in the water so that kicking can be omitted, to correctly correct swimming posture, or to improve upper body strength and waist strength. The goal is to provide a swimming assistance device that assists users so that they can focus on strengthening their muscles.

In relation to the mode of use of the swimming assistance device (1), the swimming assistance device (1) according to an embodiment of the present invention is inserted into the insertion hole (20) by the user through the cut portion (30) of the swimming assistance device (1). It is worn by inserting both legs separately. The swimming assistance device (1) fixes both the user's legs together. The user can wear the swimming assistance device 1 on the calf, knee, thigh, etc., and in a more preferred embodiment, it can be worn on the ankle.

Using the swimming assistance device (1), the user trains various swimming techniques by moving the waist left and right or swinging the arms while keeping the legs fixed. In water, the swimming assistance device (1) causes the user's lower body to float due to buoyancy. This allows users to create a variety of strokes without paying attention to the lower body. The user can move forward with a swimming stroke that alternates between the left and right sides of the user's body. This is the same swimming method in which a fish swims using its tail fin. This stroke method not only strengthens the user's upper body strength and back muscles, but also has the effect of correcting the user's distorted pelvis.

According to the swimming assistance device 1 according to an embodiment of the present invention, swimming can be done only by moving the upper body without kicking, so even people with paraplegia who cannot move their lower body at all, children with weak lower body strength, and the elderly can swim. It has the effect of making it possible.

As described above, a person 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 its technical idea or essential features. Therefore, the above-described embodiments should be understood in all respects as illustrative and not restrictive. The scope of the present invention is indicated by the claims described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the claims and the equivalent concept should be construed as being included in the scope of the present invention.
