Two opposite edges (1 and 2) of the flexible membrane (3) are attached each to one elastic strip (5). The flexible membrane (3) is made of plastic material, preferably reinforced with fibres. A preferred variant of the invention is a membrane woven with durable fibres. The strip (5) is attached to a rigid beam (6) of the base, belonging to a pair of beams connected to each other by a hinge (7) placed at a distance of 0 to 1/3 of the beam (6) length from the beam end opposite to the place of the strip (5) attachment.

Description

Collapsible swim fin
Technical field
The object of the invention is a kind of collapsible swim fin for swimming of lying fallow, move swimming or underwater operation.
Background technology
For many years, flippers is used as swimming auxiliary equipment, in particular as diving auxiliary equipment.The structure of flippers determines primarily of its desired use.Flippers for the underwater operation accurately maintaining scuba diver's submarine site have from for swim at a high speed or the flippers of deep diving has different structures.But, make integrally-built flippers by plastics or rubber and account for the market mainstream.Prominent question in these situations is weight and its size of flippers, particularly when they are transported to place to use.
From the known collapsible light swim fin of U.S. Patent Application No. US4250584.Described flippers is made up of framework, and this framework is strengthened by the tension member be pivotally connected on framework.Tension member is used for optionally locating and straining or folding flippers.Framework is made up of two semi-rigid element, and each element is divided into three different elements.First element is placed along pin and is intended to flippers to be attached to pin, and the element being attached to pin is connected with the third element at the edge being arranged essentially parallel to pin by the second element.Between the third element of framework, place a slice elastomeric material, this material is strained by means of the folding rod between the symmetric element of framework.
From U.S. Patent Application No. US4952183 known applications in the collapsible flippers of the leg of swimmer.Flippers is made up of isosceles triangle framework, and the end of its leg in the heel of framework is hingedly connected each other by the folding element forming leg-of-mutton 3rd limit of framework.Between the both sides of triangular framing, be attached fabric, described fabric is attached to its 3rd limit after framework triangle launches.
Become known for the flippers of hand and pin from U.S. Patent Application No. US4264994, wherein when swimming, the surface of described flippers is variable.Flippers is made up of the elastic membrane strained between at least two ribs.Reinforcing rib is hingedly attached to the flippers part of the pin being intended to be attached to swimmer.Articulated joint for being attached rib possesses spring.Spring bends when making rib load flippers on side, and changes when obstacle prevents surface from moving in the opposite direction.
Summary of the invention
The object of the invention is a kind of collapsible swim fin, it comprises base, arm and at arm and for flippers being attached to the elastic membrane strained between the element of the pin of swimmer.Two opposite edges (1,2) of flexible membrane (3) are attached to an elastic strip (5) separately.Flexible membrane (3) is by plastic material, be preferably made up of fibre-reinforced material.Preferred variants of the present invention is the film weaved into durable fiber.Film (5) is strengthened by fiber, preferably carbon fiber and/or Kevlar fabric and/or glass fibre and/or Fypro and/or aramid fiber.Bar (5) is attached to the buckstay (6) of base, described buckstay belongs to a pair beam be connected to each other by hinge (7), described hinge be placed on the beam-ends relative with bar (5) attachment location at a distance of beam (6) length 0 to 1/3 distance.Hinge (7) can be hinged hinge.Described hinge also may be placed on the contoured interior of beam (6) as single-axis hinge.Preferably, base beam (6) has the tubular form that cross section is rectangle or ellipse.Base beam (6) is made by plastics or steel or aluminium or titanium or with the glass of resin-bonded, polyamide, Kevlar or aramid fiber.
Base beam (6) position relative to each other can be determined by the obstacle (8) of the near outer ends being positioned at base beam (6), and other two edges of film (3) keep freely.Obstacle (8) be also used for adjust film (3) tension force.Between bar (5), wireline reel (9) is likely attached to hinge (7) for the area supported changing flippers.Preferably, a bar (5) in paired bar be attached to base beam (6) with guarantee bar around the rotating freely of its longitudinal axis time, be configured for the wireline reel (9) of the area supported changing flippers thus.From that side relative with the leg contact side of flippers and swimmer along base beam (6), likely attachment is used for the attachment rail (10) of attaching tool.In attachment rail (10), be provided with the necessary instrument of underwater operation, its mounting means can disconnect by sliding for making instrument.Instrument is arranged in attachment rail (10), is protected and can not surprisingly skid off by breech lock obstacle.Elastic strip (5) is made by plastics or with the fibre composites of resin-bonded.The fiber of bar (5) is selected from following fiber group: glass, polyamide, Kevlar, carbon fiber or aramid fiber.
Preferably, bar (5) has square-section.The cross section of bar (5) is constant along the longitudinal axis of bar (5).In another variant of the present invention, the cross section of bar (5) changes along the longitudinal axis of bar, and its mode is that the place that the thickness of bar is connected with base beam (6) at bar (5) is maximum, and is that the bar end that base beam is relative is minimum.In a special case, film (3) has the shape of the isosceles trapezoid stretched between the bar (5) of equal length.
In another variant, the bar (5) in paired bar has different length, and film (5) has the shape of the profile containing at least two straight flanges.
Bar (5) can pass through cylinder (11) and be attached to base beam (6), and described cylinder has the rotation of the longitudinal axis being parallel to bar (5).The obstacle (8) of the operation form of flippers is consisted of bolt (12), bolt one end is hingedly attached to base beam (6), and the other end is attached to another beam (6) by elliptical openings (12), and fix with lock (13), preferably nut or knob.
Flippers according to the present invention has low weight, and being articulated and connected of membrane arms allowing flippers when transporting, particularly folding when being transported to distant place dive location.The low weight of flippers and the possibility folded also contribute to organizing military equipment, march period particularly in military diving application.The use of the bar of identical or different length allows flippers to be suitable for various swimming style.The parameter that the material (its cross section and elasticity) of suitable selector bar contributes to adjusting flippers is applied to adapt to expection, that is, flippers is for swimming of lying fallow, for underwater operation or for swimming at a high speed.The energy moved from the leg of swimmer is to depend on that the flexible mode of flippers is provided to the water of surrounding.The hardness of flippers is larger, and the speed of swimming is faster.The structure of flippers allows change and the task of adaptation performed by swimmer of area supported.
