Description

Three-point swimming device

The utility model relates to a kind of swimming equipment.

At present, people's learning swim or in water when movable, for safety, generally be to adopt lifebuoy or wear life vest, be shifted easily when the former puts or come off, in case lifebuoy moves on to buttocks, the gravity center of human body changes, plant in the entry upside down, this moment, the trip head fortuitous event can occur more down more, can only keep afloat after putting on a life buoy in addition, people's leg can not become flat-hand position with the water surface, this swimming device can only be played in water, can not be as the learning swim equipment, during learning swim, also need other people upwards to hold leg and practise, and its price is more expensive.The latter is used for operation at sea safety, also can only make the people vertical with the water surface in water, can not be used for learn swim, and costs an arm and a leg heavy wearing, inconvenience.

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of simple in structure, and cost is low, and is safe in utilization, convenient, reliable, the bikini swimming device that can help the swimmer to learn to swim.

Technical solution of the present utility model:

A kind of bikini swimming device is characterized in that it is made up of waistband 1 and two arm hoops 2, on waistband 1 and two arm hoops 2 sealing air chamber 3 is arranged all, the buoyancy that they are enclosed within its three dot encapsulations air chamber 3 on the human body with people's upper body hold up with the water surface near level.

The utility model uses the supported at three point principle dexterously, scientifically swimmer's upper body is held up with the water surface near level, finish the poise of swimming.The utility model is simple in structure; with low cost, volume is little, and is in light weight; easy to carry; dress easily, safe and reliable, can eliminate the feared state of mind of beginner to water; make the relieved learning swim of casting off restrictions audaciously of beginner's energy; need not protection of others or hold up leg to help exercise, the beginner can be crossed the threshold very soon, learn the various swimming positions and the essential of exercise.The utility model not only is suitable for learning swim, also is applicable to comings and goings waterborne, also is simultaneously the good equipment of army's swimming instruction and the good assistant that the arms prisoner crosses, and is the swimming equipment that updates, and has broad prospects.

Fig. 2 is the utility model gasbag arm hoop schematic diagram;

Fig. 3 is the A-A sectional drawing of Fig. 2;

Fig. 4 is the utility model double-lumen air sac bag arm hoop schematic diagram;

Fig. 5 is the B-B sectional drawing of Fig. 4;

Fig. 6 is of the present utility model moulding firmly or foam arm hoop schematic diagram.

As figure, the sealing air chamber 3 on the utility model waistband 1 and the two arm hoops 2 can be an airbag structure, which is provided with charging connector 4, and this structure can adopt soft moulding or elastomeric material, also can be the molding structure made from duroplasts or foam.If when adopting foam to make waistband 1 and arm hoop 2, also the sealing air chamber can be made the solid structure, utilize the buoyancy of itself that human body is held up.Sealing air chamber 3 on the waistband 1 preferably be located at its middle part outer surface on (as Fig. 1), arm hoop 2 can be cylindric gasbag, which is provided with charging connector 4, charging connector 4 adopts dual fail-safe valve (as Fig. 2,3), also can be with the cylindric gasbag of arm hoop 2 along its horizontal center line pressing, make it constitute upper and lower two gasbags, respectively establish a charging connector 4(such as Fig. 4,5 above them), make each air bag volume reduce like this, thereby be unlikely the arm movement that influences the swimmer because of air bag too greatly.But arm hoop 2 is also moulded cylinder firmly, is connected with on its outer wall and moulds sealing air chamber 3(such as Fig. 6 firmly).

The learning swim person tied up to the air bag sufficient gas of waistband 1 on the waist earlier when the utility model used, put arm hoop 2 at two arms again, then respectively with they sufficient gas, get final product plunge, because the buoyancy in the sealing air chamber 3 on waistband 1 and the two arm hoops 2, the human body natural is kept afloat, be swimming preparation exercise posture, the effect of waistband 1 can guarantee that swimmer's buttocks is substantially near horizontal plane, make the swimmer be easy to learn the technical key point of grasping kick and stepping on water, the effect of arm hoop 2 can guarantee that swimmer's head breathes freely, the swimmer had both eliminated the fear to water like this, can be relieved movable freely in water audaciously, can learn various strokeses soon again, effect is very desirable.
