CN2070634U - Accelerator for swimming - Google Patents

Abstract

The utility model relates to an accelerator for raising swimming speed, which is composed of a wrapping body (1), scales (2), a fastening belt (3) and a foot belt (4). The utility model has the characteristics of light weight, convenient portability, high speed, high speed, physical strength saving, and high height of treading water and completes various difficult movements in water. When a human body swings in water to makes leg curving movement, scales (2) are closed automatically by water resistance to reduce the advancing resistance of the human body by water. When the human body makes treading movement in water, likewise, the scales (2) are opened automatically by the water resistance. The water discharge of the cross section of the scales (2) reaches the maximum, so that the swimming speed is raised instantly. The process can be repeated again and again.

Description

The swimming accelerator

The present invention relates to a kind of accelerator that is used to improve swimming rate.

As everyone knows, people's swimming that swims, if its speed is improved, depend on to a great extent from the health status of body forces and the cooperation of technical movements, muscle power consumes the then performance of influence technique action too much, swimming rate has been subjected to certain restriction for this reason, has also influenced the quality of doing various highly difficult routines in water.

Purpose of the present invention is to design a kind of like this accelerator, makes it can improve the speed that human body advances in water, can improve the height of treading the water surface again; Can free and relaxedly finish various highly difficult routines in the water, be unlikely to too much to consume people's muscle power again, and have in light weightly, easy to carry, can wrap up in band on various bodily form personnel shanks, and not have sticky feeling.Swimming accelerator of the present invention is provided by drawings and Examples.The present invention puts body (1), scale (2), binding tape (3), pin band (4) and forms by wrapping up in.Can be enclosed within during use on two calfs, tighten by binding tape (3).When the people does various strokeses and training in water, no matter select which kind of swimming mode, its elemental motion all can be decomposed into bent leg and these two kinds of motions of kicking one's legs, use accelerator of the present invention, when doing the motion of bent leg, owing to be subjected to the resistance of water and the restriction of structure of the present invention, make scale (2) auto-closing, to reduce the advance resistance of water to human body; When kicking one's legs, scale (2) is subjected to the resistance of water equally and opens automatically, and open angle is subjected to the constraint of structure and reaches 90 ° at most, and scale (2) is maximum to the contact area of water, and promptly Ci Shi drainability is maximum, makes human body obtain quickening in moment.Go round and begin again, be improved with regard to the swimming rate that makes the people.Utilize same principle, also can improve the height of treading and finish various highly difficult routine waterborne.Wrap up in and put body (1) and combine by screen and netting, screen can be made by materials such as plastics, rubber, the quantity of screen generally is no less than 2 to be symmetrical arranged to good, has slotted eye at the two ends of each piece screen, so that binding tape (3) passes wherein, convenient fixing, because when human body is done leg kicking sport in water, it is bigger that scale (2) opens resistance of water drainage automatically, wrap up in and put trend sliding on the oriented thigh of body (1), binding tape just can stop this phenomenon.Simultaneously, because pin band (4) is tied a knot on binding tape (3) around arch of the foot, make to wrap up in and put body (1) and go up sliding trend and obtain strict restriction, the making of binding tape (3), pin band (4) is very simple, material is unrestricted, except that elastic cord, the binding tape (3) with other material is made is used for fixing as long as be useful on the convenient nylon Fastener of regulating tightness at its two ends; Length direction lateral surface at screen is provided with the boss that several have 1/2 circular arc, the effect of each boss all is to be used for inlaying scale (2), scale can be made by sheet plastic and light metal, and scale (2) is just right with the Position Design of boss, and open angle can not be greater than 90 when draining to that is to say scale (2). Width two sides at screen dispose several apertures.So that cross-under netting, netting can be whole, also can be to pass the mesh that the aperture braiding forms by silk thread or arrowband, itself can regulate tightness to be fit to the thick, thin of shank.

The above is wrapped up in, and to put body (1) be the chorista that screen and netting combine, and for plastic products, also can make an integral body by the method for injection moulding pressing.

The present invention is not limited to above-described embodiment.

Claims (4)

1, a kind of accelerator that is used to improve swimming rate is characterized in that this accelerator puts body (1), scale (2), binding tape (3), pin band (4) and form by wrapping up in.

2, according to the accelerator of claim 1, it is characterized in that wrapping up in that to put body (1) be the chorista that is combined by several screens and netting, each screen is provided with several boss; Or the integral body that presses together of screen, boss, netting.

3,, it is characterized in that wrapping up in and put body (1) and make by plastics, elastomeric material according to claim 1,2 accelerator.

4,, it is characterized in that scale (2) made by plastics, metal according to the accelerator of claim 1.
