Description

Inflatable underwater exercise buoyancy device

The utility model belongs to technical field of living goods, is specifically related to a kind of inflatable underwater exercise buoyancy device of making of flexible material.

Common tradition is practised swimming utensil and is mainly contained kickboard and water wing.Kickboard is for the learning swimmer, owing to needing to live the plate face with handgrip, so be mainly used in exercise lower limb movement, function singleness; To want correct with handgrip jail and position when using, otherwise easily upset or break away from staff of kickboard in addition, make people choke water even drowned threat to life, the especially just young child of learning swim.And water wing is owing to mainly be to be placed on the trunk when using, though use than kickboard safety, both hands are freed can learn arm stroke, but its during to the human body learn swim the mechanics strong point that should provide and required natural posture unreasonable, but also can produce motor defect.In addition, if this water wing is an inflatable, because of having only an air bag, material aging cracks or valve is thrown off or cyst wall is stung or scratch gas leakage by sticker in case meet in use, also can bring safety problem.

The purpose of this utility model is to solve the problem that prior art exists, and provides a kind of more reasonable to the mechanics strong point and required natural posture that human body provided when underwater exercise, can not produce motor defect and safer inflatable underwater exercise buoyancy device.

The purpose of this utility model is reached by a kind of like this technical solution: this buoyancy device is to be made of inflatable soft air bag ring, dispose valve at the air bag ring outer surface, the girth of its inner ring surface is 12.56～60 centimetres when it is characterized in that this buoyancy device unaerated, is placed in human arm during use or/and on the lower limb.So just can make human body in water, keep way up or flat bow bubble through the water column on, learn various strokeses freely, comparatively fast and like a cork grasp swimming skills.In addition owing to be placed in human arm or/and the buoyancy device on the lower limb has two at least simultaneously, though one of them impaired gas leakage, other still can provide certain buoyancy, be unlikely and occur dangerously at once, thereby improved safety.

Specific constructive form of the present utility model or by the flexible material of two rectangles by hot pressing or bonding forming, the girth of its inside and outside anchor ring is 40～60 centimetres during unaerated, widely be 16～21 centimetres, or by the flexible material of two annular arrangements through hot pressing or bonding forming, its interior ring diameter is 4～10 centimetres during unaerated, and the diameter of outer shroud is 24～40 centimetres.

Can obtain stable geometry for after the buoyancy device of being processed by the flexible material of two rectangles is inflated, the interior wrinkle of air bag are reduced, more comfortable with service life and the wearing that prolongs air bag, following technical measures have newly also been taked in this practicality:

Make it by hot pressing to distribute in vertical cyst wall stage casing of this buoyancy device two roads or the heat seal trace more than two roads, or on the horizontal cyst wall of this buoyancy device by the hot pressing heat seal trace that distributes at least one, or on the cyst wall of this buoyancy device by the uniform point-like heat seal of hot pressing trace.

When considering that same buoyancy device can be suitable for the use problem of different people four limbs thickness variation, the technical measures that the utility model is taked are that this buoyancy device is made of a rectangle air bag, partial fixing has bindiny mechanism at the minor face edge of this rectangle air bag, as velcro or frenulum, can regulate according to the four limbs thickness by this bindiny mechanism during use, make it to form annular.

For further improving the safety in use of buoyancy device, the technical measures that the utility model is taked are to make no matter be to be distributed in heat seal trace on the vertical or horizontal cyst wall to have at least together and connect, so just can make this buoyancy device form the air chamber of two separations at least, certainly the outside face of each air chamber all will dispose valve, in case some independently air chamber gas leakage, other air chamber also can be worked in the same old way, keeps necessary buoyancy.

The flexible material that the utility model adopts can be plastics or rubber.
