Abstract

A swimming flipper is composed of a supporting frame with a water paddle on its upper part, a supporting frame with a lower foot sleeve, a pull string fixed to said water paddle and another end fixed to said supporting frame or foot sleeve, and a protecting band fixed to said supporting frame or foot sleeve and with a fastener. The utility model discloses simple structure, convenient to use do not need special training will use, also portable utilizes this swimming flipper can increase swimming power effectively, swims sooner in the water.

Description

Swim fin

The utility model relates to the instrument that can be used for swimming, and is a kind of swim fin.

At present, people in order to increase power, generally put on flippers and realize on pin, but the use difficulty of flippers are bigger when swimming, just need usually can use after the special instruction refining.

The purpose of this utility model be to design a kind of not only simply but also wield swim fin.

The purpose of this utility model reaches by following measure: the upper articulation of the support of this swim fin plate of striking, footmuff is arranged at the bottom of support, one end of stay cord is fixed on the plate of striking, and the other end is fixed on support or the footmuff, protecting band is fixedly mounted on support or the footmuff, and cingulum is arranged on protecting band; The plate of striking is hinged on the top of support by installation shaft; Two sections tops that are hinged on support respectively before and after the plate of striking divides; Two tops that are hinged on support about the plate of striking divides; Cingulum on the protecting band is instep cingulum or pin neck cingulum; Cingulum on the protecting band is instep cingulum and pin neck cingulum.

Accompanying drawing 1 is the main TV structure schematic diagram of the utility model most preferred embodiment, and accompanying drawing 2 is the side-looking user mode schematic diagram of accompanying drawing 1, and the coding in the accompanying drawing is respectively: 1 is support, and 2 for striking plate, 3 is stay cord, and 4 is footmuff, and 5 is protecting band, 6 is the instep cingulum, and 7 is pin neck cingulum, and 8 is installation shaft.

Below in conjunction with most preferred embodiment and accompanying drawing the utility model is further described:

Shown in attached Fig. 1 and 2, the upper articulation of the support 1 of this swim fin plate 2 of striking, footmuff 4 is arranged at the bottom of support 1, one end of stay cord 3 is fixed on the plate 2 of striking, and the other end is fixed on support 1 or the footmuff 4, and protecting band 5 is fixedly mounted on support 1 or the footmuff 4, on protecting band 5 cingulum is arranged; In when swimming, this swim fin is through on the pin, when pin in water backward during paddling, under the effect of water and stay cord, the plate 2 of striking opens certain angle, the resistance bigger, and this resistance reacts on human body to water generates, thereby human body is travelled forward; When receiving pin forward, under the effect of water, the plate 2 of striking is to support 1 or footmuff 5 closures, thus the resistance when having reduced resistance to water and having reduced promptly that water travels forward to human body; Week and return and help human body and in water, move about forward like this; The utility model is easy to use, does not need special instruction refining to use.

Shown in attached Fig. 1 and 2, the plate 2 of striking is hinged on the top of support 1 by installation shaft 8, is convenient to install the plate 2 of striking like this; Two sections tops that are hinged on support 1 respectively before and after the plate 2 of striking preferably divides, when walking after leaving from water like this, the plate 2 that is difficult for striking dismounts badly; As shown in Figure 1, two tops that are hinged on support 1 about the plate 2 of striking preferably divides can increase the power of striking like this; As shown in Figure 2, cingulum on the protecting band 5 can be instep cingulum 6 or pin neck cingulum 7, is used to prevent footmuff 4 slippage from the pin, and cingulum also can be instep cingulum 6 and pin neck cingulum 7, with instep cingulum 6 and pin neck cingulum 7 the utility model is fixed on the pin so simultaneously, just more firm.

The utility model is simple in structure, easy to use, also is easy to carry, and utilizes this swim fin can increase swimming power effectively, faster in the water middle reaches.
