Description

A kind of variable double tail finses equipment for being used to swim

Technical field

The present invention relates to swimming device and diving equipment industry, more particularly to a kind of variable double tail finses dress for being used to swim It is standby, for swimming exercise, underwater swimming, can both swim soon at a high speed, can also low speed roaming, patrolled particularly suitable for water middle and long distance Trip.

Background technology

Contemporary society, swimming exercise and underwater swimming are increasingly popularized, and various swimming devices, diving equipment emerge in an endless stream, Most of swimming device and diving equipment be all using flippers as the main driving tool to advance, common are double-legged double webs and The single web of both feet, the double webs of both feet are that the both feet of swimmer respectively wear a flippers, and swimmer is kicked alternately by both legs and produces what is advanced Motive force, the single web of both feet are that the both feet of swimmer wear a flippers altogether, and swimmer is synchronously fetched water by both legs and produces pushing away for advance Power.

The either double webs of both feet or the single web of both feet, have its most suitable single frequency of fetching water, swimmer is only with this Frequency of fetching water is fetched water, and could obtain optimal propulsive force；When swimmer wishes to change trip speed, for example fetched water height with higher frequency Fast fast trip or with relatively low frequency fetch water low speed roaming when, the efficiency of propulsion can decline, especially when swimmer is with higher Frequency when fetching water, not only propulsive efficiency is not high, but also can produce sense of fatigue quickly；In addition, either double-legged double webs are still The single web of both feet, is through on swimmer's pin, because leg and pin have an angle, flippers is fetched water caused propulsive force side It is completely the same to the direction that can not necessarily advance with swimmer, thus also weaken propulsive efficiency.

Existing most of swimming device and diving equipment are all difficult to thoroughly solve the day that human body adapts to land walking Right structure and such conflict that freely moved about in water；Since the time immemorial ancestors of the mankind leave ocean come land life with Afterwards, body structure is slowly changed, and the structure for originally adapting to move about in ocean is gradually degenerated, disappeared, and the substitute is The structure of land walking is adapted to, therefore, when the mankind, which turn again to, is engaged in swimming exercise in water, can not be swung again as fish Tail fin, leisure are travelling.

The content of the invention

Do not had for the double webs of main driving tool both feet, the single web of both feet of current existing swimming device and diving equipment The human body preferably solved is not suitable with water efficiently travelling natural motion fault of construction, and be difficult in fast trip at a high speed and The weak point of higher propulsive efficiency can be obtained under low speed roaming two states, the present inventor returns to dolphin, cetacean etc. The process of the mammal oscillating tail-fin of Ocean Living is examined, studied, and dolphin, cetacean are imitated in water with the mankind The travelling posture of oscillating tail-fin compares, and compares difference therebetween, is made a concrete analysis of again for the reason for generation difference, With reference to human motion structure feature, by scientifically and rationally using ergonomics, there is provided go out a kind of variable double tails for being used to swim Fin is equipped, and the equipment can be according to trip of the swimmer in water speed, swinging kick frequency, the variable tail fin device of swinging kick amplitude adjustment Fin broadening degree or fin developable surface product, reach the fast trip at a high speed that can both be fetched water with higher frequency, can also be beaten with relatively low frequency Water low speed roams, and no matter is fetched water under which kind of frequency, and swimmer can effectively improve the proportion of useful work, and with intelligence with Fast variation characteristic, so as to the advance efficiency and trip speed that lifting is swum and dived under water to greatest extent, swimmer is given full play of in water In traveling potential, and then the purpose continuously cruised over long distances；Swimmer is cruised by intelligent speed changing, can also effectively be dropped Low long range is cruised caused sense of fatigue；In addition, the variable double tail finses equipment produces the direction and swimmer traveling side of thrust To completely the same, deposited so as to overcome the leg of double-legged double webs or the single web of both feet caused by being worn on swimmer's pin with web Fetched water caused the defects of promoting force direction completely the same with the direction of swimmer's advance in angle and then web, so as to enter One step improves propulsive efficiency.

The present invention specifically uses following scheme：

A kind of variable double tail finses equipment for being used to swim, including left tail fin, right tail fin, double tail finses fix bar, left tail fin, the right side Tail fin is placed in double tail finses fix bar both sides and to be connected with double tail finses fix bar, and left tail fin and right tail fin are parallel to each other, left tail Fin exhibition variable-width or fin exhibition variable area of the fin plus right tail fin.

The left tail fin, right tail fin pass through at least one tail fin articulated structure each other and double tail finses fix bar phase Connection, left tail fin, right tail fin are rotatable as spindle central using the pin joint of tail fin articulated structure；Under normal circumstances, left tail fin with Between double tail finses fix bar, a tail fin articulated structure is respectively set between right tail fin and double tail finses fix bar, can also be by the institute 2 articulated structures stated merge into 1, i.e., left tail fin, right tail fin are articulated with 1 point；The tail fin articulated structure includes tail fin Link bolt axle, tail fin are hinged shaft end nut；It can ensure to rotate in a manner of the flank of tooth is mutually twisted between left tail fin, right tail fin Synchronism.

The left tail fin, right tail fin, the joining mode of double tail finses fix bar include but is not limited to hinge-coupled mode, cunning Dynamic to coordinate connecting mode, the i.e. main tail fin of the connecting mode that is slidably matched and secondary tail fin couple sliding rail each other each other Together, above two connecting mode can realize similar function, i.e., left tail fin, right tail fin, double tail finses fix bar that It can relatively rotate or relatively move between this, accordingly the cunning between the left tail fin, right tail fin, double tail finses fix bar Dynamic rail road is curve track or rectilinear orbit.

The fin broadening degree refers to that main tail fin adds the horizontal spreading width of secondary tail fin, is analogous to the span-width of birds； The fin developable surface product refers to that main tail fin adds the developed area of secondary tail fin, is analogous to the span area of birds.
