Energy-Saving Mode of Freely Staying in Water

Abstract

The present inventions relates to the field of human activities involving staying in water, in particular, in immobile or immobilized states. The claimed technical result reduces to ensuring highly stable staying at the surface of deep water, in particular, under conditions of considerable water surface roughness. According to the proposed invention, the face is turned up, the head is straightened, the legs are flexed, the arms are drawn aside and turned outside, and the forearms are flexed. Alternatively, the arms are straightened and the thighs are flexed or the arms are flexed and the thighs are straightened. Some distinctive features are related to additional technical means, which facilitate realization of the present invention.

Description

FIELD OF THE INVENTION[0001]The present inventions relates to the field of human activities involving staying in water, in particular, it can be used in order to teach swimming and escape drawing, in the course of physical training and auto-training, and in sports, medicine, etc.BACKGROUND[0002]There are various modes of swimming (see, e.g., description of RU Patent No. 2,003,370 C1), which employ auxiliary means in order to increase buoyancy of the human body. Such means, while offering convenient aid in learning of unskilled swimmers, do not help to overcome the main difficulty, that is, fear to sink into water (fear of depth). These auxiliary means are rather misleading, making an unskilled swimmer dependent on the availability of such technical aid. In order to make possible the use of the auxiliary means of increasing buoyancy, these devices, despite their relatively large dimensions, must be always at hand. A special class of means that is worth of mentioning includes lifebelt...

AI Technical Summary

Benefits of technology

[0008]The present invention is aimed at developing the known modes of swimming, including those employing auxiliary means. The invention provides comfortable staying at the water surface (with only certain parts of the face such as nose, chin, mouth, elbows, eyes, and forehead occurring above the surface) without using any additional means and / or supports. The disclosed invention is also intended to facilitate the teaching process, impart sense of security and buoyancy to a learner, and accelerate his adaptation to aqueous element.

[0009]In creating the present invention, problems have been solved in order to(i) develop the optimum modes of grouping the body, still admitting simple energy-saving motions necessary to maintain desired orientation in water and to restore peripheral blood flow;(ii) find a convenient start position that precedes active swimming (leading to motion of the body center of gravity);(iii) provide auxiliary means facilitating realization of the present invention by various individuals, including those with restricted mobility of joints, under conditions of prolonged staying in water and / or considerable water surface roughness.

[0010]The technical result that can be achieved due to implementation of the present invention is as follows:(1) eliminating stress related to staying in water far from supports;(2) ensuring high stability of staying in water without movements, even at large perturbations of the water surface;(3) providing the possibility of full body rest with effective muscle relaxation during prolonged staying in both sea and river (salt and fresh) water far from supports, with effective relaxation of muscles which are predominantly involved in motions during active swimming;(4) expanding the possibility of staying in water far from supports for individuals with restricted mobility of joints;(5) ensuring therapeutic and prophylactic unloading of joints, spinal column, etc.(6) ensuring prophylaxis of disorders in respiratory apparatus;(7) providing the possibility to use auxiliary means (compact devices) in order to increase buoyancy, which perform additional functions as the elements of equipment;(8) offering convenient arrangement of search and survival means on the body.

[0019]The arms are flexed until they will be perpendicular to the water surface to within ±30°. In flexing arms, the effort necessary to perform or maintain the aforementioned bending can be reduced with the aid of an auxiliary device.

[0022]A snorkel can be used so as to eliminate the admission of water to the respiratory tract (breathing passages). In particular, the inspiration or all respiratory movements can be blocked when water occurs in the snorkel.

[0023]It is also possible to use special nose clamps, which prevent the admission of water into the nasal tract.

Problems solved by technology

Such means, while offering convenient aid in learning of unskilled swimmers, do not help to overcome the main difficulty, that is, fear to sink into water (fear of depth).

These auxiliary means are rather misleading, making an unskilled swimmer dependent on the availability of such technical aid.

However, real practice shows that a swimmer occurring on a rough water surface usually cannot correctly and timely assess the situation and prevent (by breath-holding) the admission of water into his respiratory tract (breathing passages).

Snorkels are not at all applicable in rescuing unconscious persons.

One disadvantage of the prototype is the need for continuously performing motions with hands in order to stabilize the position of a body relative to the water surface.

Another disadvantage of said prototype is a significant deviation of the body center of gravity toward legs from the vertical line passing through the point of application of the buoyancy force.
