Abstract

The utility model relates to sports equipment and is intended for the accelerated movement of a swimmer on water or in a draw using muscular strength. The objective of the claimed utility model is to create an energy-saving device for the movement of a swimmer, both on water and under water. The technical result in solving the problem is to increase the efficiency of the device for the movement of the swimmer. The essence of the claimed utility model consists in the fact that the body consists of a platform for placing a swimmer with stops for shoulders, a telescopic rod, its front part connected to the platform, and the back part through a flexible connection or a swivel with a vertical fin. The telescopic rod serves to fit the device according to the swimmer's height. On the fin in the area of connection with the bar, there are foot rests, alternately acting on which the swimmer causes the fin to oscillate in the horizontal plane. The platform for the swimmer is equipped with a fairing with a glass porthole in the floor and in the front. The platform with a fairing can be equipped with cavities or, for example, made hollow to fill them with air (when swimming on water) or water (when swimming under water). For this, the cavities are equipped with a fitting with a valve, by means of which it is possible to control the degree of filling of the cavities with water and, thus, the buoyancy of the entire device. In addition, changing the direction of movement of the claimed device (up and down) can be carried out by horizontal rudders with control handles located on the site.

Description

A device for scuba diving is known, consisting of a mover made in the form of flippers, a rotary lever with holders for legs and a hip belt connected to the mover by a flexible connection (USSR Author's Certificate No. 188872).

The disadvantage of this design is the presence of a flexible connection, which does not allow to achieve an ordered movement of the mover in the process of its oscillatory movement under the influence of the muscular strength of the swimmer's legs.

A device is also known for moving a swimmer under water, comprising a body with means for fixing the swimmer, rudders mounted on the front of the body with handles for controlling the direction of movement, a thruster made in the form of a fin, and a foot pedal associated with it (UK Patent No. 1144305) .

By the combination of essential features, this design is closest to the claimed utility model and is selected as a prototype.

The disadvantage of the prototype is the presence of a pedal mechanism, in the hinges of which, due to friction, a part of the swimmer’s energy (muscular strength) is lost when he presses the pedals to create oscillatory motion of the fin.

In addition, the disadvantage of both the analogue and the prototype is the lack of any means to facilitate the swimmer’s diving / surfacing, except for rudders with handles, as in the prototype, which help the swimmer, for example, when diving, but the main load at these moments swimmer's legs to create extra effort to overcome the buoyancy of water.

The objective of the claimed utility model is to create an energy-saving device for the movement of a swimmer, both on water and under water.

The technical result in solving the problem is to increase the efficiency of the device for the movement of the swimmer, which is also facilitated by the presence in the proposed device of the fairing and cavities that create positive / negative buoyancy of the device.

The essence of the claimed utility model consists in the fact that the body consists of a platform for placing a swimmer with stops for shoulders, a telescopic rod, its front part connected to the platform, and the back part through a flexible connection or a swivel with a vertical fin. The telescopic rod serves to fit the device according to the swimmer's height. On the fin in the area of connection with the rod are located

emphasis for legs, alternately acting on which the swimmer causes fluctuations of the fin in the horizontal plane. The platform for the swimmer is equipped with a fairing with a glass porthole in the floor and in the front. The platform with a fairing can be equipped with cavities or, for example, made hollow to fill them with air (when swimming on water) or water (when swimming under water). For this, the cavities are equipped with a fitting with a valve, by means of which it is possible to control the degree of filling of the cavities with water and, thus, the buoyancy of the entire device. In addition, a change in the direction of movement of the inventive device (up and down) can be carried out by horizontal rudders with control handles located on the site.

In Fig.1 shows a device for moving a swimmer sideways, Fig.2 is a top view.

A device for moving a swimmer consists of a platform 1 for accommodating a swimmer, equipped with stops 2 for his shoulders and equipped with a fairing 3. The platform 1 and fairing 3 have viewing windows 4, as well as cavities 5, equipped with fittings 6 with valves for air / water inlet / outlet . The horizontal rudders 7 located in the lower part of the platform 1 are connected to the control levers 8. The platform 1, through the telescopic rod 9, is connected to the vertical fin 10 by means of a flexible connection 11, and the fin 10 has stops for legs 12, which are equipped with means for fixing the legs 13, for example, in the form of belts.

A device for moving a swimmer is used as follows.

The swimmer places his body on the platform 1, clinging to the shoulder rests 2, and grabs the control handles 8. Then he places his legs on the rests 12, having preliminarily sized the device in size using the telescopic rod 9. Using his feet on the stops 12, the swimmer brings action fin 10, which, making oscillating movements in the horizontal plane, moves the device forward.

The device is controlled as follows.

A swimmer, moving on the proposed device by water, can rotate by creating a roll to the right or left side, moving the body to the right or left on the site, as well as manipulating the rudders 7, which, using the handles 8, can rotate independently of each other, creating a moment rotation of the entire apparatus around the longitudinal axis.

To control the pitch of the device, the cavity 5 through the nozzles 6 are filled with water and the device with a swimmer is immersed in water. When the device moves underwater, the swimmer

using the rudders 7, can change the depth of immersion and rotate the device as well as in the above-water position.

To ascend to the surface, you can use the rudders 7, and also, if the swimmer swims with a scuba diving, he has the ability to remove water from the cavities 5 through the nozzle 6, which will increase the positive buoyancy of the device and, thus, facilitate ascent.

To ensure visual observation when controlling the proposed device, the swimmer uses portholes 4 in the platform 1 and fairing 3
