Description

The invention relates to the field of sports and recreation, in particular to devices for swimming with a mask and scuba diving, as well as for archaeological and underwater rescue operations and can be used for diving and surfacing a diver.

Known diving breathing apparatus containing a container of compressed air, connected through a flexible hose with a locking device with a pulmonary apparatus, providing a respiratory process. The known device is equipped with a vest that provides the diver with positive buoyancy by filling it with compressed air from the cylinder (RU, U1, No. 143132, 2014).

The purpose of the known solution is to perform various work underwater and does not imply the possibility of free swimming on the water surface, in connection with which it does not have the ability to repeatedly change the buoyancy by venting the buoyancy vest during multiple dives, as well as the ability to switch the breathing mode through the breathing tube to a cylinder of compressed gas and vice versa.

Closest to the claimed invention is a device for scuba diving, containing a half mask, a breathing tube and an airtight container in the form of an elastic bag pneumatically connected to the internal cavity of the mask through a flexible hose with a locking element (RU, C1, No. 2214849, 2003). The known solution allows the scuba diver to move on the water surface and to carry out a one-time dive by switching the breathing mode through the tube to breathing through an elastic bag. The replenishment of the air supply is carried out due to the natural filling of the inner cavity of the bag during the restoration of its volume under the influence of a spiral.

A disadvantage of the known solution is a small amount of air in the elastic bag, since it is filled with atmospheric air. In addition, the replenishment of air without outside assistance is possible only on the shore, due to its inconvenient location, not a swimmer. In addition, swimming underwater with an elastic bag with a supply of air on the back is very difficult and requires considerable effort.

The claimed invention is aimed at expanding the functionality by providing the possibility of repeated diving, as well as increasing the duration of the swimmer's stay under water.

The specified technical result is achieved in that in a swimming device containing a mask, a breathing tube and an airtight container for air, pneumatically connected to the internal cavity of the mask through a flexible hose with a locking element, characterized in that the air tank is made in the form of a container of compressed air, connected through a system of gears and a breathing mode switch with a buoyancy change element in the form of an elastic tight vest with a pressure relief valve.

The mask is made full face.

The device is equipped with an additional emergency ascent balloon associated with a sealed vest and made with a sensor of the maximum depth of immersion, as well as an emergency ascent button.

The pressure relief valve is made three-way.

Since the claimed device differs from the known number of essential features, it meets the condition of patentability "novelty."

The claimed device does not contradict the well-known laws of physics of mechanics, which allows us to claim their compliance with the patentability condition "industrial applicability".

The claimed device is aimed at solving the problem of providing the swimmer the possibility of multiple diving without the need to replenish the air supply on the shore, which allows us to conclude that it meets the patentability condition of "inventive step".

The presented sketch shows a schematic diagram of the claimed device.

The swimming device comprises an atmospheric breathing tube 1 with a shut-off valve that acts when immersed in water, a full-face mask 2, connected by flexible elastic hoses 3 with an autonomous air supply system including a compact compressed air cylinder 4, a high pressure reducer 5, a second stage reducer 6, elastic sealed variable buoyancy vest 7 with pressure relief valve 8, connected through a three-way breathing mode switch 9 with a control button 10 mounted on the side of the hour 7 and vest.

The device is equipped with an additional disposable balloon for emergency ascent with compressed gas through the emergency valve 12 and valve 13 are connected through a flexible reinforced hose with a sealed vest 7, which is made with a built-in sensor (not shown) of the maximum depth of immersion, as well as a button or cord for emergency ascent (not shown).

From the vest 7, air is removed through the channel 14.

The device operates as follows.

If it is necessary to dive and stay at a depth for several minutes, the swimmer switches the breathing mode control button 9 located on the chest and transfers from the air access system from the tube 1 to a compact autonomous air supply system attached to the vest 7, for which the swimmer only switches the control button 9 to the corresponding position. All subsequent actions occur automatically: breathing comes from balloon 4 through the original valve system of the full-face mask 2, which is configured to automatically change the air supply from balloon 4 to replace atmospheric.

The weight compensation system also works automatically: air from the elastic-filled vest 7 originally filled by it is discharged through the channel 14 into the external environment, as a result of which the volume of the vest 7 decreases under the influence of the pressure of the surrounding water. The weight of a person with equipment and initially installed loads becomes more than the volume of displaced water and the swimmer dives without his own efforts.

Upon reaching a depth of 5-6 meters, the swimmer can examine the subject of interest for several minutes and, after completing the study of the subject, press the control button 9 to its original position. In this case, the air from the balloon 4 begins to flow into the vest 7, and the swimmer floats to the surface. After the ascent, the breath automatically switches to atmospheric air through the tube 1 with the valve, and the air supply from the cylinder 4 - stops. You can make several dives. The total diving time is limited by the capacity of the cylinder 4 with air.

If the swimmer dives to a depth of more than the specified maximum (7 meters or more), the safety valve 12 is automatically activated, adjusted to a predetermined pressure corresponding to the maximum safe depth of immersion) In this case, a separate cylinder 10 with compressed gas is connected automatically and fills the volume of the vest 7, causing the swimmer to pop up. The design of the vest 7 provides a constant location of the head of the swimmer above the surface of the water.

An emergency ascent of a swimmer on his initiative, in case of problems with the presence of air in the air supply system or for other reasons, provides a security system. To do this, it is enough for the swimmer to pull the emergency ascent cord connected to the valve 12, as a result of which the gas from the cylinder 10 enters the vest 7 through the valve 13. The emergency ascent system disables the air supply system to the vest 7 from the cylinder 4 by a check valve 8. Restoring the cylinder 4 and replacement of the cylinder 10 of the emergency ascent system, as well as the translation of the valve 13 to its original position, to ensure safety, is carried out on the shore.
