State of the art

Known Dog: Newfoundland is a dog breed originally used as a working dog in Canada. They are large dogs with long, dense black, brown or black and white hair and a thick undercoat, white patches on the chest and legs are allowed. The Newfoundland has membranes between the toes.

Newfoundland in Russia is sometimes called a diver.

Newfoundland is devoid of aggression towards people. This quality is also a product of selection. A dog working side by side with people in very difficult, dangerous conditions should be just that. Moreover, a dog capable of throwing itself into the water on command (or without any command) to save a drowning person. Therefore, you should not start a Newfoundland "for protection". For this he loves people too much. However, this does not mean that in a dangerous situation, the Newfoundland will not be able to fend for itself or its owner. But it is useless to incite him - he will make the decision himself. The attacking Newfoundland is a very impressive sight. The main protective technique that these dogs do not need to be taught is to stand between the owner and the offender, in extreme cases - to knock the offender down. This is not difficult, with an adult male weighing 70-80 kg. Under no circumstances is Newfoundland able to seriously bite a human.

Newfoundland is pleased to be of service. He will be happy to carry a light bag in his teeth, carry around his neck an arbitrarily heavy sled with any load, look after children (everyone, including "strangers"), especially on the water - in no case will he let the child in deeper than he reaches the bottom with his paws. The attitude towards children is especially worth noting: Newfoundlands are extremely patient creatures. Where the willpower is not enough for either a person or a shepherd dog, the Newfoundland will stoically endure all the bullying of children, and even control their actions.

Fins are known - Fins in anatomy are paddle-like limbs that function as organs of movement, rudders of depth and rotation in vertebrates that have secondarily switched to the aquatic lifestyle (sea turtles, penguins, seals, walruses, whales).

Fins in sports are a device (of the same shape) for swimming (also see fins propeller).

Source: https://ru.wikipedia.org/wiki/Fins

Known flippers - a device for swimming (propulsion) in the form of a fin or oar. They are put on the legs (although hand fins are also known).

There are two options for scuba diving:

1) Regular fins, one for each leg

2) A monofin is two fins spliced into one. Usually a monofin has a larger area than two conventional fins. Due to the fact that both legs are fastened together, the monofin swimming style resembles a dolphin or a fish: forward movement is carried out by undulating movements of the whole body.

Fins are distinguished:

By heel type:

1.with a closed heel - either a bare leg or wearing a special sock is inserted into such a fin;

2.with an open heel (equipped with a tightening strap or a pressure spring) - fins can only be used with shoes, otherwise you can rub your feet into the blood, however, such fins are more versatile (can be used with both wet wetsuits and all modifications of dry suits) , and the shoes allow you to walk on stones, protecting your feet from cuts;

By blade material:

1.Carbon fiber reinforced plastic are the most effective, since the energy of elastic deformation to the greatest extent goes into the swimmer's push;

2. fiberglass, one of the most effective, since the energy of elastic deformation to the greatest extent passes into the swimmer's push;

3. plastic, low efficiency due to low elasticity, that is, the ratio of the force spent on deformation to the force of returning the blade to its original state;

4. rubber, the least effective, since the deformation energy is mainly spent on interlayer friction and passes into heating;

Note: It should be understood that when buying a blade from a manufacturer other than an overshoes, the butt of the plates must be sawed to match the shape of the butt of the original blade and not just stick the blade into the overshoot and drill holes for the fasteners "in place" ... Moreover, sometimes you need to grind the rubber flange itself (which can be large and not fit into the seats of the "mustache" of the galoshes), sometimes the end of the blade is also processed, giving it the shape of a semicircle, since this shape is more maneuverable and less inclined to touch everything under water when swimming ... Since the efficiency of the rubber "mustache" galoshes are smaller than fiberglass and carbon fiber reinforced plastics, so often they try to make the mustache thinner or grind it so that they do not interfere with the work of high-efficiency plates.

By blade stiffness:

1. hard ones are optimal for people weighing from ~ 100 kg or more;

2. medium, for people weighing from 75 to 95 kg;

3. soft, for people weighing up to ~ 75 kg;

By the shape of the blade:

1.Bending angle in the butt of ~ 22 degrees is universal for both diving and swimming on the surface, 15 degrees or less is optimal only for swimming under water and extremely tiresome for the swimmer when swimming on the surface;

2. for diving and snorkeling;

3. for freediving and spear fishing;

4. monofin for freediving and speed swimming;

The essence

The technical result, which is solved by the invention, is provided by the unused possibility of effective movement of the dog in the water, in order to implement the rescue function, carrying out various works in conditions of immersion of a person in water, research activities, diving activities, idle leisure activities by people.

To solve this technical problem, dog fins are offered.

Dog fins, consisting of a fixing pad, attachment belts, thigh harness, finger harnesses and designed to fix the dog's paw to ensure the working function of the mechanism, as well as oars, characterized in that the oars are connected to the fixing pad by a hinge joint, and the fixing pad is equipped with stops, preemptive development of the deviation of the oars in connection with the implementation of a hydrodynamic attack on the body of water in order to reproduce the driving force. At the same time, the oar is made with a cone-shaped protrusion, which serves as a confuser in order to open the oar to carry out a hydrodynamic attack on the body of water in order to reproduce the driving force.

On the reverse of the swinging movement of the animal's limb, the design of the oar assumes instability in relation to the resistance of the water body, due to the absence of stops and moves with minimal resistance.

The author considers it possible to propose his mechanism as an invention applicable specifically to dogs, in particular those performing a rescue function, since he believes that a similar principle of the device of fins for use by a person can be absorbed by the claimed formula of the present invention.

The applicant did not find other known technical solutions for a similar purpose with a similar set of essential features when conducting a search in scientific and technical literature and patent documentation.

The main technical features and advantages of the proposed technical solution are described in the presented preferred embodiment.

The scope of protection of the invention is not limited to the described example, but includes various embodiments in accordance with the general concept. In particular, the ability of the oars to open up to carry out a hydrodynamic attack and take the position of minimum streamlining on the reverse of the swing motion.
