Abstract
A kind of device for exercising swim, lifesaving dual-purpose clothing relate to swimming auxiliaring appliance.The present invention makes the people float in water than the level land by the asymmetric configuration at buoyancy position before and after human body.Help to learn the swimmer and grasp water-based safely, association's swimming makes not natatory people also can enjoy the enjoyment of swimming.In lifesaving, can make the people that bigger initiative ability is arranged.
Description
Technical field: swimming, lifesaving.
Prior art: the 1. life jacket of front and back buoyancy symmetry and similar products thereof.
2. be not fixed on the buoy quoit of human body.
3. be enclosed within the water wing on the arm.
Purpose: make people obtain freedom waterborne.In physical culture, allow people grasp water-based with playing for safety.
In lifesaving, make people that bigger initiative ability is arranged.
Content: on the basis of floating, in conjunction with swimming requirement:
1. on the enough basis of gross buoyancy, upper breast is equipped with the nose heave buoyancy in 2/3rds left and right sides, to guarantee that head floats on the surface all the time.
2. back buoyancy is greater than chest buoyancy, to guarantee the back all the time up, in order to avoid the water of choking.
3. back buoyancy is near burst portion, keeps human body flat tiltedly in water when swimming like this, easily moves about and is difficult for sinking.
4. buoyancy only fits over body part, and what constraint arms and legs is not had.
5. can easily draw oneself up and stand.Gross buoyancy is not too big, and front and back buoyancy difference is reasonable.
Compare with the technology of on-fixed on human body such as buoy quoits:
Flat-floating life jacket can be liberated both hands, does not have the danger of loss of buoyance.
Compare with life jacket etc.: flat-floating life jacket can make the people move about at the water surface easily.
Its good effect: will be to learn the swimmer to be willing to use, and can grasp water-based with playing for safety, and help reducing because of the number that is not able to swim or water-based is bad and drowned.
Best implementation method: buoyant mass can be made two kinds of gas and solids, and can and adjust buoyancy according to swimming and personal touch's increase and decrease.
Claims (1)
- The invention belongs to swimming, the lifesaving technology field.Immediate with the present invention in the prior art is balanced configuration buoyancy before and after human body, keeps the life jacket technology in the upright water of human body.Feature of the present invention is to dispose buoyancy before and after human body asymmetricly, and the human body on even keel is floated in water.
