Description
Technical field
The invention belongs to sports apparatus technical field, relate to a kind of swim fin.
Background technology
Swim as a part for daily life amusement, very large effect is played to the fitness improving people.Flippers, as the aid of swimming, can contribute to the speed that swimmer improves swimming, increase the diversity of swimming, thus adds the interest of people to swimming to a great extent.
Existing flippers is owing to being only applicable to freestyle swimming in subaqua swimming, backstroke, the fetching water of butterfly stroke by the restriction of its structure, and for breaststroke, traditional flippers but can not effectively play auxiliary effect, this is because existing flippers structure in swimming process can not change, and cannot adapt to the change requirement of kick action in breaststroke process.
Summary of the invention
The object of the present invention is to provide a kind of tensile force type swim fin, this flippers can solve the restriction to action in particularly breaststroke process of swimming of existing flippers, can be used for fetching water, being used for kick again, make it all can play auxiliary effect to various stroke.
The know-why of tensile force type swim fin of the present invention is as follows:
A kind of tensile force type swim fin, comprises ankle cover, web body, pulley, some elasticity lattice framings and some the line of pull corresponding with elasticity lattice framing; Wherein ankle cover is fixed on the position that web body top contacts with ankle, and pulley is fixed on the position with heel contact bottom web body; Some elasticity lattice framings are that on the fan-shaped web shape face be evenly distributed on bottom web body, the concentrated end of elasticity lattice framing is positioned at the position contacted with ankle bottom web body, and dispersion end is then distributed in the diverse location place of web body bottom tip; Some line of pull one end are fixed on the dispersion end of corresponding elasticity lattice framing, and the other end is fixed on ankle after walking around pulley and puts, and what when the length of line of pull makes ankle bend kick, elasticity lattice framing was followed in web shape face is bent to form arcwall face.
In above-mentioned tensile force type swim fin, ankle cover is stiff annular pull strap.
In above-mentioned tensile force type swim fin, annular pull strap is with pulling buckle.
In above-mentioned tensile force type swim fin, pulley and elasticity are propped up strip adoption light material and are made.
In above-mentioned tensile force type swim fin, elasticity is propped up strip adoption lightweight steel bar and is made.
The Advantageous Effects that the present invention has is as follows:
1, the elasticity lattice framing that adds in the bottom of web body of the present invention and line of pull structure, when making ankle bend kick, line of pull pulls elasticity lattice framing, what make web shape face follow elasticity lattice framing is bent to form arcwall face, very large thrust is produced to water, and when ankle stretch fetch water and clap water time, elasticity lattice framing is free state, web shape face is also in free state, thus web shape face produces two kinds of changes along with the action of pin, be applicable to the strokes of multiple human hair combing waste power, as freestyle swimming, backstroke, the fetching water and the kick of breaststroke of butterfly stroke, tool has been widely used and generalization.
2, the elasticity lattice framing that adds in the bottom of web body of the present invention, adds elasticity at the bottom of web and suppleness and then reduces thickness and the weight of flippers self.

Detailed description of the invention
The object of the present invention is to provide a kind of tensile force type swim fin that can be used in kick and fetch water, below in conjunction with accompanying drawing, its structure detailed description of the invention is described.
As shown in Figure 1, Figure 2 and Figure 3, tensile force type swim fin imitates duck's foot operation principle and designs, comprise ankle cover 5, web body 1, elasticity lattice framing 2, line of pull 3, pulley 4 five part, web body 1 is divided into and is through part 9 on pin and sole web bottom part, be through pin upper part for playing fixing flippers effect, web bottom part, for the effect playing kick and fetch water, is similar to the web body between duck's foot toe.Wherein ankle cover 5 is fixed on the position that web body 1 top contacts with ankle, and pulley 4 is fixed on the position of web body bottom and heel contact; Elasticity lattice framing 2 is some, be evenly distributed on the web shape face of web body bottom in fan-shaped, the two ends of elasticity lattice framing 2 are respectively concentrated end 7 and dispersion end 8, and concentrated end 7 is positioned at the position that web body bottom contacts with ankle, and dispersion 8, end is distributed in the diverse location place of web body tip; Between elasticity lattice framing 2 is distributed at the bottom of web, being similar to the toe of duck's foot, during for limiting shape at the bottom of web and kick, playing the effect of resiliency supported; Elasticity lattice framing 2 is for supporting the effect at the bottom of web, and its elasticity meets the strength that pedal water elasticity can sustain kick, and when pin is fetched water, its elasticity can not impact the free bend at the bottom of web.
One end of some line of pull 3 is fixed on the dispersion end 8 of corresponding elasticity lattice framing 2, and the other end is fixed on ankle cover 5 after walking around pulley 4, for limiting curved shape and the direction of elasticity lattice framing 2; What when the length of line of pull 3 makes ankle bend kick, elasticity lattice framing 2 was followed in web shape face is bent to form arcwall face.
Pulley 4 is fixed on the rear heel place of flippers, pulley plane is parallel with human body sagittal plane, triangular in shape plaing a part supports and fixed block support for supporting pulley, pulley 4 is mainly used in the contact friction force reducing line of pull, raise the fulcrum that heel is formed simultaneously, with improvement result power angle, pulley 4 and elastic support 2 can select light material to make.Wherein the steel bar of the good lightweight of elastic support 2 preferred elastomeric is made.
As shown in Figure 2, ankle cover 5 is the annular pull strap of inelastic straps pulling buckle, is around in ankle arthrosis place, and ankle cover rear portion is fixed in one end of line of pull 3; Can make with non-elastic material, the pulling buckle of front openings is easy to dress in the process of dressing, the effect that fixing line of pull is played at ankle arthrosis place can be fixed in the process of swimming, and the width of ankle cover is moderate, be unlikely to produce too large pressure to heel in the process of swimming, can not too widely cause dress uncomfortable.Line of pull 3 is several, with elasticity lattice framing 2 one_to_one corresponding, one end is fixed on the dispersion end 8 of flippers elasticity lattice framing and before pulley 4, is gathered into one so that walk around pulley, is fixed on ankle and overlaps 5 rear portions after walking around pulley 4, the optional line with having larger pulling force of line of pull 3.
Fig. 3 is the side direction structure chart of tensile force type flippers of the present invention, the situation that when only giving kick in figure, ankle is bending, when ankle bends, the shank that flippers is through part on pin 9 and human body is in close to the angle of 90 °, at this moment line of pull 3 pairs of elasticity lattice framings 2 produce pulling force, make at the bottom of web, to form recurvate arcwall face, thus the active force that can produce during kick, when breaststroke, flippers plays auxiliaring effect.And when pin stretch freely fetch water time, the shank that flippers is through part on pin 9 and human body is in much larger than the angle of 90 °, at this moment limit by line of pull 3 length, line of pull loosens, active force is not produced to elasticity lattice framing 2, at this moment web bottom part is original free state, and when fetching water, web bottom part freely swings with water, plays the effect of auxiliary swimming equally.
The present invention is by the effect of line of pull 3 pairs of elasticity lattice framings 2 two kinds of modes, and when achieving kick and fetch water, the swimming auxiliaring effect of two kinds of modes, has promotional value widely.
