example 1

[0014] The base beam 6 is made of aluminum profiles with a square cross section, and is hingedly connected by a hinge 7 located on the base beam 6 at a distance of 1 / 10 of the length of the base beam 6 from the end of the beam. The hinge 7 consists of a rigid pin 14 whose ends are mounted to a shaft 15 attached vertically in the base beam 6 . After the flipper has been unfolded into a usable form, a beam position barrier 8 is placed near the end of the beam 6 . The barrier 8 is formed by a bolt 12 hinged to the beam 6 and carried through an oval opening 13 in the other beam 6 . An elastic strip 5 made of carbon fiber composite and polyester resin is removably attached to each beam 6 . The strips 5 have the same length and, along their entire length, a uniform cross-section. A regular trapezoidal leg of membrane 3 is attached to each strip. Straps 17 for attaching the fins to the swimmer's legs run between the base beams 6 . The modification of the support surface of the fl...

[0016] The flippers use strips 5 of different lengths and membranes 3 of irregular shape. The base beams 6 are made of aluminum profiles with a square cross-section, and are hingedly connected to each other by a hinge 7 , which is located on the base beam 6 at a distance of 1 / 10 of the length of the base beam 6 from the end of the beam. The hinge 7 consists of a rigid pin 15 whose ends are mounted to a shaft 16 attached vertically in the base beam 6 . After the flipper has been unfolded into a usable form, a beam position barrier 8 is placed near the end of the beam 6 . The barrier 8 is formed by a bolt 12 hinged to the beam 6 and carried through an oval opening 13 in the other beam 6 . An elastic strip 5 made of carbon fiber composite and polyester resin is removably attached to each beam 6 . The strip 5 has different lengths and has a uniform cross-section along its entire length. A quadrangular leg of membrane 3 is attached to each strip. Straps 17 for attaching the fin...

[0018] The base beams 6 of the flippers made of titanium profiles with a square section are hingedly connected to each other by hinges 7 , and the hinges are located on the base beam 6 at a distance of 1 / 10 of the length of the base beam 6 from the end of the base beam 6 . The hinge 7 consists of a rigid pin 15 whose ends are mounted to a shaft 16 attached vertically in the base beam 6 . Near the end of the beam 6, a barrier 8 for the position of the beam is placed after the flipper has been unfolded into a usable form. The barrier 8 is formed by a bolt 12 hinged to the beam 6 and carried through an oval opening 13 in the other beam 6 . One of the strips 5 of the pair of strips is attached to the base beam 6 to ensure the free rotation of the strip about its longitudinal axis and constitutes the winding axis 9 of the membrane 3, the base beam 6 is provided on the extension of the titanium profile The bottom plate 19 serves to place the axis of rotation 11 located in the front...

Abstract

A folding swim fin which comprises a base, arms, and an elastic membrane tensioned between the arms and elements for attaching the fin to the swimmer's feet. 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

technical field [0001] The object of the invention is a folding swimming fin for recreational swimming, sport swimming or underwater work. Background technique [0002] For many years fins have been used as swimming aids, especially as diving aids. The construction of a fin is primarily determined by its intended use. Fins for underwater work for accurately maintaining a diver's underwater position have a different configuration from fins for high-speed swimming or deep diving. However, flippers with integral structures made of plastic or rubber dominate the market. A significant problem in these cases is the weight of the fins as well as their dimensions, especially when transporting them to the place of use. [0003] Folding light swimming fins are known from US Patent Application No. US4250584. The flippers consist of a frame reinforced by tensile members pivotally connected to the frame. Tensile members are used to selectively position and tension or fold the fin. ...
