Description

{SWIMMING ASSISTANCE APPARATUS}

The present invention relates to a swimming assistance device. More particularly, to a swimming assistance device that provides buoyancy to a portion of a user's body in water to assist the user in correcting the swimming posture or focusing on upper body strength and lumbar muscle strengthening.

Swimming is one of the whole body exercises that strengthens the vital capacity and endurance and strengthens the whole body. Therefore, swimming in the world such as South Korea, the United States, Australia, Japan, China is getting popular as a living sport.

Conventional swimming aids include tubes, buoys, and boards. The tube is in the form of a donut. The user may wear the tube to wrap the waist or wear the tube to support the user's upper body by wrapping one side of the tube by hand. The buoy is 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 in the form of a plate. The user holds the board and is assisted by buoyancy.

Korean Patent No. 10-1212467 Korean Patent No. 10-1171002

Conventional swimming aids such as tubes, buoys, and boards, however, must be held by the user when swimming. Therefore, the arm motion of the user is generally hindered. Thereby, the user can not perform the swimming posture completely using the conventional swimming assistance device.

Also, since the conventional swimming assistant device is easily disengaged from the user's hand, a novice who can not swim can miss the conventional swimming assistant device. For a beginner, this experience provides a sense of avoidance or rejection of water, leaving a long-term trauma in the beginner's head.

Further, when using a conventional swimming assistant device, the user always has to tense the muscles of the arm. As a result, the user is easily tired and does not have confidence in swimming. Also, since the muscles are tense, it is difficult to calibrate the swimming posture smoothly.

In addition, in the case of a conventional sphygmomanometer or a conventional sphygmomanometer, there is a problem that only the lower body except for the upper body can be trained. This is because when the user grasps the board with both hands, the two arms and the body are stretched straight and the forward movement is advanced by the kicking motion.

In addition, in the case of a vest type mouthpiece among conventional swimming assist devices, there is a limitation in the stroke method and there is a problem that it is difficult for a user to hold a posture in water. This is because the user floats vertically in water by the vest type buoy.

In addition, there are considerable limitations to the realization that can be realized when using conventional swimming assistance devices. In general, if a conventional swimming assistant device is used, it is possible to swim the waist only up and down. Such a method can further increase the back pain for patients suffering back pain with a back disk or the like.

In the case of disabled persons with disabilities such as paraplegia, it is impossible to make a kick or swim up and down the waist. Therefore, disabled people with disabilities could not use conventional swimming aids.

Accordingly, the present invention has been made to solve the above-described problems.
