Description:

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to an aqua-gym device, and more particularly to an exercise device for guiding a user to perform exercise in water.

2. Description of Related Arts

A conventional training device, such as a swimming exerciser or a swimming harness, usually comprises a plurality of resilient members extended from a supporter to a connector worn on a user's body when he or she is swimming in a swimming pool. Typically, the supporter is a fixture positioned adjacent to the swimming pool and one end of each of the resilient members is detachably affixed to the fixture while another ends of the resilient members are affixed to the connector.

One type of swimming exerciser is that the resilient elements are affixed to the ladder of the swimming pool so that the user may swim in the swimming pool while the resilient elements are attached to his or her body and exert backward pulling force thereto. One advantage of this type of swimming exercise is that it provides great freedom to the user so that the user may swim in the swimming pool in virtually any direction. The disadvantage of this type of the swimming exerciser is that the control over the movement of the user is too loose. As a result, this type of swimming exerciser is not suitable for handicap or those who require therapy because they need substantial guiding when they swim in the pool in order to prevent deterioration of their health condition.

A second type of swimming exerciser is that the resilient elements are affixed to the ladder of the swimming pool so that the user may swim in the swimming pool while the resilient elements are attached to two sides of his or her body and exert sideward pulling force thereto. An advantage of this type of swimming exerciser is that the user is guided from sideward and there is no need to have any supporting member suspendedly extended above the water surface. The disadvantage, however, of this type of swimming exerciser is that the resilient elements of the swimming exerciser are not capable of preventing sinking of the user's body. In other words, the user of this type of swimming exerciser is not guided to float on the water surface. When the user of the swimming exerciser is physically disabled or handicapped, the situation can become very dangerous.

All of the above-mentioned conventional swimming exercisers also share another disadvantage which relates to their limited application. The swimming exercisers mentioned above are only capable of guiding a user to swim in a pool area. They do not, however, guide the user to perform other kinds of exercises in that pool area. Thus, if the user wishes to perform a certain kind of exercise in water other than swimming, he or she has to do it by himself or herself without any aid. This also presents danger to the user.

SUMMARY OF THE PRESENT INVENTION

The invention is advantageous in that it provides an aqua-gym device which is an exercise device for guiding a user to perform exercise in water. The aqua-gym of the present invention is especially suitable for the handicapped or elderly people.

Another advantage of the invention is to provide an aqua-gym device which is capable of guiding a user to swim and to perform certain exercises in a water pool. In other words, the present invention not only guides the user to swim, but also assists the user to perform a wide range of exercises not relating to swimming in the pool. As such, the present invention is not limited to assist swimming.

Another advantage of the invention is to provide an aqua-gym device which is capable of guiding the user in the pool from various orientations so as to provide a safety net when the user loses self-control (due to health conditions) in the water.

Another advantage of the invention is to provide an aqua-gym device which comprises a water tank which can be assembled to securely store a predetermined amount of water for facilitating safe and guided exercise activities in the water tank. Moreover, the water tank has light weight for easy transportation.

Another advantage of the invention is to provide an aqua-gym device which is capable of mitigating lower back pain, sharp pain in the back of user's legs, herniated discs, numbness in legs, shooting hip or buttock pain.

Additional advantages and features of the invention will become apparent from the description which follows, and may be realized by means of the instrumentalities and combinations particular point out in the appended claims.

According to the present invention, the foregoing and other objects and advantages are attained by providing an aqua-gym device for assisting a user to exercise in water, comprising:

a supporting frame suspendedly supported above a water surface;

a training connector detachably attached to the user; and

an elastic element having a first elastic portion having one end movably connected to the supporting frame, and another end movably connected to the training connector such that the first elastic element is arranged to exert an upward force to the user for substantially assisting the user to float in the water, wherein the elastic element further has a second elastic portion having one end movably connected to the supporting frame, and another end movably connected to the training connector such that the second elastic element is arranged to exert a backward pulling force to the user, so that when the user exercises in the water, the first and the elastic element substantially guide the user by assisting the user to float in the water and providing a guiding force to the user.
