Cruising suit for swimming and diving

Abstract

The invention discloses a cruising suit for swimming and diving. The cruising suit comprises an upper swimsuit and a lower swimsuit. The rigid upper swimsuit is flat, has a small front and a big back,and wraps a swimmer from the head to the trunk. The flexible lower swimsuit is cylindrical, has a large front and a small back, and wraps the swimmer from the trunk to the feet. The flexible lower swimsuit is connected with the upper swimsuit into an integrated structure on the trunk of the swimmer. The front end, wrapping the head part of the swimmer, of the upper swimsuit is provided with a cushioning device or a small airbag, the cylindrical tail end of the lower swimsuit is shrunken into an annular sealing ring which is hooped into an annular groove corresponding to a bionic tail fin fixing rod of a bionic tail fin, the bionic tail fin fixing rod is fixed between the swimmer's legs or feet, At least one side of the front and back sides, covering the back or the chest and abdomen, of the upper swimsuit is provided with a respiration tube which is hinged to the upper swimsuit, the retracting statuses of the respiration tube is controlled by a respiration tube automatic retracting mechanism, and at least one air chamber or liquid chamber which communicates with an automatic liquid-air pumping device is arranged between the upper swimsuit and the lower swimsuit and the body of theswimmer.

Description

technical field [0001] The invention relates to swimming equipment and diving equipment industries, in particular to a cruising suit for swimming and diving, which is used for swimming and diving sports, and is especially suitable for long-distance high-speed cruising in relatively wide waters. Background technique [0002] In contemporary society, swimming and diving are becoming more and more popular, and various swimming equipment and diving equipment emerge in an endless stream. It is a common combination to use diving suits with flippers and respirators, which can swim on the water or sneak underwater. , the flippers include double-footed bi-fins that use both feet to fetch water alternately, and double-footed mono-fins that use both feet to fetch water synchronously, but overall, the propulsion efficiency is not high, and a considerable proportion of swimmers' physical energy is consumed doing useless work In terms of speed, it is difficult to achieve a high swimming s...

[0002] In contemporary society, swimming and diving are becoming more and more popular, and various swimming equipment and diving equipment emerge in an endless stream. It is a common combination to use diving suits with flippers and respirators, which can swim on the water or sneak underwater. , the flippers include double-footed bi-fins that use both feet to fetch water alternately, and double-footed mono-fins that use both feet to fetch water synchronously, but overall, the propulsion efficiency is not high, and a considerable proportion of swimmers' physical energy is consumed doing useless work In terms of speed, it is difficult to reach a high swimming speed, and you will feel tired when the distance is a little longer, so it is impossible to achieve long-distance high-speed cruising

[0003] The reasons for the low propulsion efficiency mainly come from three aspects. First, the existing diving suits are designed according to the shape characteristics of the human body. Although they can better match the human body shape and are more comfortable to wear, they are not suitable for swimming in water The principle of the least linear forward resistance is far from the body shape of whales, dolphins, sharks, tuna or sailfish; the second is the propulsion tools, that is, the propulsion efficiency of flippers is not high. The propulsion efficiency of the double-foot monofin with feet synchronously kicking water is higher than that of the double-foot bifin that uses alternate feet to kick water, but there is still a big gap compared with the tail fins of whales, dolphins, sharks, tuna, and sailfish; Finally, human bones and muscles exist to adapt to walking and running on land, while the bones and muscles of whales, dolphins, sharks, tuna, and sailfish exist to adapt to efficient swimming in water. In terms of shape and muscle strength, human beings are far behind the latter
