Description
Technical field
The present invention relates to swimming devices and diving equipment industry, in particular to one kind is with fast variation rigidity flippers, for swimming
Movement, underwater swimming.
Background technique
Contemporary society, swimming exercise and underwater swimming are more more and more universal, and various swimming devices, diving equipment emerge one after another,
It is the main driving tool to advance that most of swimming device and diving equipment, which are all with flippers, common are both feet and respectively wears one
The double webs of both feet only and both feet wear one single web of both feet altogether, and there are also the bionic caudal fin that both feet wear one altogether, the double webs of both feet are trips
Swimmer is kicked alternately the motive force for generating and advancing by both legs, and both feet list web and bionic caudal fin are that swimmer beats by the way that both legs are synchronous
Aquatic products before death into motive force.
The either double webs of both feet, the single web of both feet or bionic caudal fin, there is its most suitable single frequency of fetching water, swimmer
It is only fetched water with the frequency of fetching water, optimal propulsive force could be obtained；Speed is swum when swimmer wishes to change, such as with higher frequency
Rate fetch water the fast trip of high speed or with lower frequency fetch water low speed swim slowly when, the efficiency of propulsion can decline, and especially work as swimming
When person is fetched water with higher frequency, not only propulsive efficiency is not high, but also can generate feeling of fatigue quickly.
Summary of the invention
For the double webs of the main driving tool of current existing swimming device and diving equipment both feet, the single web of both feet and bionical
Tail fin does not have preferably to solve obtain higher propulsive efficiency not in the case where two states are swum in the fast trip of high speed and low speed slowly
Foot place, the present inventor combine human motion structure feature, by scientifically and rationally using ergonomics, provide one kind with speed
Variation rigidity flippers, by this with fast variation rigidity flippers, swimmer can be fetched water the fast trip of high speed with higher frequency, can also with compared with
Low frequency low speed of fetching water is swum slowly, with the variation of trip speed or the variation of swimmer's swinging kick frequency, with the change of fast variation rigidity flippers
The rigidity of rigidity longitudinal keel changes therewith, no matter fetches water under which kind of frequency, swimmer can effectively improve useful
The specific gravity of function promotes the advance efficiency of swimming and diving to the maximum extent and swims speed and save physical strength, gives full play of swimmer
Traveling potential in water is finally reached long-time, the purpose that long range continuous high speed is cruised；Swimmer is cruised by speed change,
The feeling of fatigue generated when long range can also be effectively reduced, continuously cruising for a long time.
The present invention specifically uses following scheme:
One kind is with fast variation rigidity flippers, including paddle blade and longitudinal keel, it is characterised in that: positioned at the longitudinal direction side of the paddle blade
The longitudinal keel on the side or middle part at least one variation rigidity longitudinal keel for variable rigidity, the flippers include that both feet are worn altogether
The single web of one both feet, both feet respectively wear one double web of both feet, further include the bionic caudal fin that both feet wear one altogether, and both feet list web is
Dolphin web.
The longitudinal keel of double-legged list web is usually left and right two, is located at the two of the left and right sides of the paddle blade of double-legged single web
In longitudinal side, it is generally the case that two longitudinal keels are variation rigidity longitudinal keel；The longitudinal keel of bionic caudal fin is logical
Often also it is left and right two, is located in two longitudinal sides of the left and right sides of the fin keel of bionic caudal fin, it is generally the case that should
Two longitudinal keels are also variation rigidity longitudinal keel.The longitudinal keel of each flippers of double-legged double webs is generally also left and right two
Root is located in two longitudinal sides of the left and right sides of each flippers of double-legged double webs, it is generally the case that this two vertical
It is also variation rigidity longitudinal keel to keel.Longitudinal side is longitudinal profile outer.
Rigid rod that the variation rigidity longitudinal keel includes at least one section and at least one rigidity are with velocity modulation regulating device, institute
It is end to end or be hidden in inside hollow rigid rod with velocity modulation regulating device and rigid rod to state rigidity.
The rigidity being hidden in inside hollow rigid rod includes the Taper Pipe of rigid rod inner hollow with velocity modulation regulating device, with
And the non-newtonian fluid that is provided with of Taper Pipe or the cone bar that is total to longitudinal axis with Taper Pipe and can be vertically moved along the longitudinal axis of Taper Pipe, when rigid
When degree is made of with velocity modulation regulating device Taper Pipe and cone bar, the cone bar that being also equipped between Taper Pipe and cone bar makes to vertically move resets
Reseting elastic element, it is described cone bar include section girth consecutive variations smooth surface cone bar, also include section girth
The stepped surfaces cone bar discontinuously changed, the stepped surfaces cone bar include the stepped surfaces type cone that length is fixed, shape is fixed
Shape bar and length is variable, telescopic telescopic antenna type cone cell bar.The smooth surface of the section girth consecutive variations bores bar,
The smooth surface type cone cell bar that usually length is fixed, shape is fixed.
The preceding paragraph fall described in the rigid rod of variation rigidity longitudinal keel be whole hollow Taper Pipe, advance from swimmer
The front one end in direction is all to the cross-sectional profiles perimeter of rear one end of swimmer's direction of travel and the cavity cross section of inside
Length is gradually reduced, and bores the cross-sectional profiles perimeter of bar from front one end of swimmer's direction of travel to swimmer's direction of travel
Rear one end is also gradually reduced accordingly.For smooth surface type cone cell bar, stepped surfaces type cone cell bar, be equipped in Taper Pipe by
Pull-up reseting elastic element acts on the compressible type reseting elastic element being equipped in its stub end or Taper Pipe and acts on its microcephaly
End, the direction for forcing it to advance to swimmer reset, stub end, that is, court of smooth surface type cone cell bar, stepped surfaces type cone cell bar
To the front end of swimmer's direction of travel, small head end, that is, rear end；For telescopic antenna type cone cell bar, be equipped in Taper Pipe by pull-up multiple
The hollow telescopic joints at different levels that position elastic element passes through telescopic antenna type cone cell bar act on cross section week among telescopic joints at different levels
Long the smallest final stage bar towards the compressible type reseting elastic element effect being equipped in the front end of swimmer's direction of travel or Taper Pipe
The smallest final stage bar of section girth towards swimmer's direction of travel among the telescopic joints at different levels of telescopic antenna type cone cell bar
Rear end, the final stage bar i.e. work as under the fully extended state of telescopic antenna type cone cell bar telescopic joints at different levels towards swimmer traveling side
To that grade of bar of the least significant end counted up, it is generally the case that Flexible Reset member is used by pull-up Flexible Reset member, for example stretches bullet
Spring or rubber band advance biggish one end of section girth that one end is fixed on the hollow Taper Pipe towards swimmer
On the inner wall of the front end in direction, the other end passes through the hollow telescopic joints at different levels and telescopic antenna type cone cell of telescopic antenna type cone cell bar
