Description

The device is a water vehicle driven by a swimmer.

A device is known for saving people on the water in case of ship accidents or accidents, both for rescuers and for those rescued by quickly leaving the scene of the accident, as well as for entertainment and sports purposes by providing a high swimming speed, containing a float and blades made flat, streamlined, made of materials such as polystyrene foam or from flexible spring plates such as foam rubber, additional blades of a bucket or funnel shape are installed next to the blades, RF patent No. 2494913, 10/10/2013.

The disadvantage of this device is its complexity and inefficiency. The forces on the arms and legs are not evenly distributed. A swimmer with one hand should raise one lobe above the water, with the other hand make a stroke in the water with the second lobe, and spend a large amount of energy to raise the blades above the water level. At the same time, the swimmer’s body wriggles in the water, which makes it impossible to use the legs when swimming.

A device for swimming, containing a frame with means for attaching it to the swimmer’s body and a longitudinal guide, RF patent 2102096, 01.20.1998.

The hollow rod is mounted in the guide with the possibility of reciprocating movement from the efforts of the swimmer's legs. To do this, the rod is movably thrust. One (front) end of the rod is pivotally connected to the blade, pivotally mounted on the rod. The trailing end of the traction is pivotally connected to the axis of the stirrup assembly located in the foot lifting region. The axis in the area of the fingers of the stirrup assembly is pivotally connected to the bar by means of traction. By pulling the knees of the legs forward, the bar also moves forward. Pulling off his socks, the swimmer turns the stirrup knot. The axis and traction move forward a distance limited by a groove in the bar. The thrust acts on the blade, and the latter rotates from vertical to horizontal. When the stop is returned to its original position, the blade turns to a vertical position, making a stroke.

The device has a complex structure and is inefficient in operation. To move in water, only the efforts of the swimmer's legs are used. The blade in the device is alternately, then in a vertical, then in a horizontal position. The blade works effectively when it is in relation to the surface of the water in one position, in the vertical.

A device for saving people on the water and for speed swimming is known. Application for utility model No. 2015139423 from 09.16.2015.

The device contains at least one blade and one float, handles, the blade has inlet openings and inlet valves. A swimmer, holding the device with both hands by the handles and moving it forward - backward parallel to the surface of the water, moves forward. The blade is constantly in a vertical position relative to the surface of the water.

The disadvantage of this device is its low efficiency due to the fact that only the swimmer's hands work with the device during swimming.

The problem to which the invention is directed is to increase the efficiency of the device.

This problem is solved due to the fact that the Surninov’s swimming device, characterized in that it contains two manual blades, two foot blades, a manual crossbar connecting the manual blades, a foot bar connecting the foot blades, elastic rods connecting the manual blades with the foot blades, pedals with foot mounts mounted on the foot rail, floats mounted above each blade, all blades containing inlet openings, inlet valves and valve travel limiters, the blades themselves and they have a bucket shape.

The technical result provided by the given set of features is the effective use of the efforts of the hands and feet of a swimmer to move on water.

When using the proposed device, there is no need to raise the blades above the surface of the water and lower them into the water. This is a time consuming process. While swimming on the device, both the arms and legs of the swimmer work.

Swimmer, moving his arms and legs to the front and back of the blade parallel to the surface of the water, moves forward. In this case, the forces on the arms and legs are distributed evenly.

The invention is illustrated in the drawing, which shows the proposed device. The Figure shows a device, a top view and a side view.

Surninov’s swimming device, characterized in that it contains two hand blades 1, two foot blades 2, a hand rail 3 connecting the hand blades 1, a foot bar 4 connecting the foot blades 3, elastic rods 5 connecting the hand blades 1 to the foot blades 2 , pedals 6 with mounts for legs 7, mounted on the foot rail 4, floats 8 and 9, mounted above each blade 1 and 2, life vest 10, mask 11 and swimming pipe 12, while all blades 1 and 2 contain inlet openings 13, intake valves 14 and restrictions the stroke of the valves 15, and the blades 1 and 2 themselves have a bucket shape.

The device operates as follows.

The swimmer puts on a life jacket 10, fastens it, tightens and fixes the vest belts passing between the swimmer’s legs (the belts are not shown in the drawing), connects the hand blades 1 with the foot blades 2 with elastic rods 5, puts on a swimming mask 11 and inserts in the mouth the tube for swimming 12, fixes the tube 12 on the head. Then he brings the device into the water and lays down on the water so that the hands held the horizontal bar 3, and the feet were in the foot mounts 6.

A swimmer, being in the water, moves horizontally lobes 1 and 2 forward - backward and moves forward.

Pulling the hand-bar 3 to the chest, the swimmer makes the stroke with the hand blades 1. At the same time, bending the legs at the knees, the swimmer advances the foot blades 2.

Then, pushing the foot blades 2 with his feet back, the swimmer makes a leg kick. At the same time, the swimmer advances the manual 1 blades, then to make another stroke with his hands.

As a result of alternating strokes with hand blades 1 and foot blades 2, the swimmer moves forward.

At his request, the swimmer can make a turn, for which the swimmer must shift the manual 1 vanes in the direction of rotation.

During the strokes, the surface of the blades 1 and 2 are continuous tight planes, since the inlet openings 13 are closed by the inlet valves 14. When the blades 1 and 2 are moved forward, the blades are a sieve, since the valves 14 are open and pass water through the inlet openings 13. For moving the blades 1 and 2 forward, the swimmer applies much less effort to them than when doing the strokes.

The stroke limiters of the valves 15 stabilize the operation of the intake valves 14, allowing the valves to deviate only 90 degrees from the vertical position.

The ladle-shaped blades 1 and 2 interact with a larger mass of water than flat blades and more efficiently transform the swimmer's efforts into movement energy during the swimmer's strokes.

The proposed device for swimming contains two hand blades 1 connected by a hand rail 3 and two foot blades 2 connected by a foot bar 4. The blades 1 and 2 are located to the left and right of the swimmer's body. This allows the swimmer to see the situation in the water ahead of him and evenly distribute the load on his legs and arms.

The device contains elastic rods 5 connecting the manual blades 1 with the foot blades 2. The rods combine the device into a single whole and contribute to a better distribution of the swimmer's efforts when moving through water.

Pedals 6 with mounts for legs 7 are installed on the foot rail 4. Mounts for legs 7 on pedals 6 can be made in the form of stirrups. This will allow the swimmer to easily insert their feet into the stirrups and easily remove their legs from the mounts.

In the device, the floats 8 and 9 installed above each blade 1 and 2. This arrangement of the floats 8 and 9 above the blades 1 and 2 contributes to better stability of the device and the swimmer on the water.

The front part of the floats 8 and 9 from the bottom can be beveled, and the rear part is thickened. This design of the floats 8 and 9 reduces the hydrodynamic resistance when the floats move forward on the water, and the thickening of the rear part of the floats prevents the transfusion of water through the floats during strokes by the blades 1 and 2, which reduces the efficiency of the device. These design features of the floats can also increase the efficiency of the entire device.

Floats 8 and 9 can be made inflatable. This design of the floats will reduce the volume of the device during its transportation and storage.

The device contains a life jacket 10. The presence of a life jacket 10 in the device increases the safety of using the device on the water. If the swimmer's health worsens, the swimmer will not drown, even if the hand blades are released from the hands. 1

The presence in the device of a mask for swimming 11 and a tube for swimming 12 will provide the swimmer with a comfortable environment when swimming on the device and increase the efficiency of the entire device.

Manual bar 3 may have bends corresponding to the physiological structure of human hands. A swimmer can work effectively in water, provided that the subject with the person matches the structure of his hands. Examples of changing the relief of straight objects are known and used, for example, in the manufacture of ski poles and vultures of disk dumbbells. As a result, skiers and weightlifters, without much tension in their hands, effectively use ski poles and vultures of disk dumbbells. In the proposed device for swimming, the swimmer will be able to more effectively use the handrail 3 in the presence of bends on her hands (bends of the handrail 3 in the drawing are not shown).

In form, the proposed device resembles a large water spider, so the device is inconvenient during transportation and storage. To reduce the size during transportation and during storage, the device can be made collapsible. For example, floats 8 and 9, crossbars 3 and 4 can be disconnected from the blades 1 and 2, and pedals 6 can be disconnected from the crossbar of the foot 4.

Two manual blades 1 can be made in the form of one double blade with one float. This design mono blade manual will expand the application of the proposed device. To implement this option, the hand blade should be equipped with handles extended towards the swimmer.

The design of a mono blade of manual non-bucket shape is described in the application of the Russian Federation for utility model No. 2015139423 of 09.16.2015.

In the device, pedals 6 with mounts for legs 7 can be mounted on the horizontal bar of the manual 3 manual blades 1. Several swimmers can take advantage of such modular blades and arrange group swimming in the water, combined in chains.

Foot blades 2 can be disconnected and fixed on the swimmer's legs. This option of using foot blades 2 will increase the swimmer’s maneuverability when moving him over the surface of the water and under water. The blades may be under the pedals of each leg or on the side of the swimmer's feet and lower legs.

The author made and tested on the water a manual mono blade with a bucket shape.

The bucket-shaped monofin, together with the float and handles, has positive buoyancy. The weight of the mono blade assembly is 3.2 kg, the volume is 16.3 dm ³ . The float with an area of 370 × 540 × 77 mm ^{3 is} made of a dense foam sheet. As the base of the blade, a pallet from the oven of an electric furnace with an area of 322 × 366 mm ² , consisting of a frame measuring 322 × 398 mm ² , formed by a steel bar with a diameter of 5 mm, to which 14 steel rods with a diameter of 3 mm and a length of 320 are welded in parallel to each other, was used. mm at a distance of 23 mm from each other. Intake valves 14, made of a polyvinyl chloride plate 311 × 29 × 1 mm ^{3 in} size, material density 1.34 g / cm ³ , are fixed to the rods using bends formed by the plates themselves. In the vertical position of the blade valves 14 freely deviate from a vertical position to a horizontal position and back. The blade contains 14 inlets 13 with a size of 312 × 21 mm ² . Part of the frame is recessed into the float to a depth of 30 mm, and the frame itself is held on the float in this position by the upper ends of the handles. Handles are made of sanitary polypropylene tubes reinforced with aluminum with a diameter of 20 mm and a length of 1700 mm each. The tubes are double-bent, and the ends of the tubes are attached to the corners of the blade with metal brackets. The upper ends of the tubes are attached to the float with metal brackets. The bends of the handle tubes that the swimmer holds with his hands are 350 mm apart and 620 mm from the mono blade.

In order to provide a mono blade with a bucket-like shape, around the perimeter of the blade there is a plate made of polyethylene 3.3 mm thick and 80 mm wide. The bucket-like shape of the blade allows the swimmer to interact more effectively with the aquatic environment through the use of a greater mass of water for their movement than when using a non-bucket-shaped blade. On the walls of the framing plate, the stroke limiters of the valves 15 are installed in the form of screws screwed into the plate with a length of 30 mm and a diameter of 3 mm opposite each inlet valve 14, allowing the valves to deviate only 90 degrees from the vertical position.

A swimmer, holding the mono blade with his hands by the handles and moving the blade forward - backward, moves forward. When moving the blade forward, the inlet valves 14 are open and pass water through the inlet openings 13. When performing a mono-blade stroke, the inlet 14 valves lower by gravity and close the inlet openings 13. The stroke of the mono blade during swimming is 10-20 cm.

The author measured the efforts that a swimmer puts on the handles of a mono-bucket-shaped blade when moving it in water. In order to move the bucket-shaped mono-blade forward at a speed of 0.5 m / s, the swimmer must apply a force of 1.2 kgf to the blade handles. During the stroke, when pulling the mono-bucket-shaped blades toward himself at a speed of 1 m / s, the swimmer must apply a force of approximately 12 kgf to the blade handles. At the same speeds of movement of the mono blade of a non-bucket shape, the effort on the arms is 1 kgf and 8 kgf, respectively.

As elastic rods 5, a Shock Corol elastic braid with a diameter of 6 mm can be used, manufacturer DiveRite, used in diving to attach and fix underwater equipment, or a surgical latex hose with a diameter of 5 mm, tel. 8 495 664 30 65.

As floats 8 and 9 can be used buoy for sea fishing company "Shardana" size 90 × 45 × 11 cm ³ , keeping a person on the water, or an inflatable buoy raft company "Atoll".

As a life jacket 10 can be used a vest of Russian manufacturers, for example, the company LLC Cyclone, St. Petersburg, as well as foreign manufacturers, for example, Life Vest.

A mask, a tube for swimming 11 and 12, for example, of the Jossno brand, can be bought at a price of 999 rubles. in specialized stores selling equipment for swimming.

The device can be used in professional activities, to save people on the water, in sports, for entertainment on the water and learning to swim.
