Description

The invention relates to the field of livelihoods of animals, namely to muzzles for dogs, and can find application in everyday life and in official dog breeding.

Known muzzle, consisting of interconnected rods, while the left and right halves of the muzzle are pivotally connected using an axis, with the possibility of closing it on the mouth of the animal by means of a lock. For disclosure, in case of operational necessity, the muzzle is made in the form of a device consisting of pushers in the form of pusher sleeves strung on a cable-leash until they stop in the lower part of the thrust thrust ring, and in the upper part - a pusher spring-loaded with a power spring, fixed trigger button mounted in the handle of the leash (RF patent No. 2370026, IPC АКК 25/00, publ. 10/20/09).

The disadvantage of this analogue is walking the animal only on a leash. The closest in technical essence and the achieved result to the proposed one is the muzzle for dogs, containing the main shaping element with notches that cover the dog’s round muzzle, and the elements that cover the dog’s mouth in front and fasten the muzzle on the dog’s neck with the help of an adjustment strap that runs along the top of the head . The notches are made at the level of the cheekbones of the dog. The element covering the mouth of the dog in front is equipped with an insert of rigidity. The muzzle elements are made of two layers, the upper of which is made of genuine leather (RF patent No. 2203538, IPC A01K 25/00, publ. 05/10/2003).

The disadvantage of the prototype device is the inability to quickly remove the muzzle from the dog at a distance from the owner in case of attack by attackers on the owner of the dog or in order to protect himself.

The objective of the invention is to create a simple and reliable operation of the muzzle device, the design of which makes it possible to remove the muzzle from the dog at a distance from the owner.

The problem is solved using the signs specified in the 1st claim that are common with the prototype, such as a dog muzzle, containing the main forming element covering the dog’s round face, connected by fasteners in the form of belts with a collar and buckle, and distinctive essential features such as a collar equipped with an electromechanical latch with a control system and an elastic metal plate located between the layers of the collar.

A feature of the design of the electromechanical latch is reflected in paragraph 2 of the claims, namely, the electromechanical latch contains in the connector at one end a mate of the latch, and at the other end - a lock part containing electrical and mechanical parts on the base, while a spring loaded spring is installed on the mate of the collar latch with a fixing pin, with the ability to move along the curved cutout of a large gear interacting with a small gear connected by a worm mounted on and the shaft of the electric motor, which is electrically connected to the power element and the control system located on the circuit board of the electrical part of the latch.

The design feature of the control system of the electromechanical latch of the dog’s muzzle is reflected in paragraph 3 of the claims, namely, it includes a microcontroller, the first input of which is connected to the output of the receiver, the second input is connected to the position sensor of the large gear, and the first output of the microcontroller is connected to the indicating device, the second output with an actuator - a latch electric motor, while the microcontroller, receiver and electric motor are connected to a power source.

The above set of essential features allows you to get the following technical result - the ability to remove the muzzle from the dog at a distance from the owner.

The invention is illustrated by the following drawings. Figure 1 - General view of the muzzle; figure 2 - a muzzle, a view with an open latch; figure 3 - latch in the closed state; figure 4 - latch in the open state; 5 is a section along BB-3; 6 is a locking recess of the gear; 7 is a block diagram of a control system; Fig - algorithm of the device.

The muzzle for dogs (Fig. 1) contains the main forming element 1 that covers the dog’s round face, connected by fasteners in the form of belts 2 with a collar 3 and a buckle 4. The collar 3 is equipped with an electromechanical latch 5 with a control system and an elastic metal plate 6 located between collar layers 3. Figure 2 shows a muzzle with an open latch.

The electromechanical latch 5 (figure 3) contains in the connector AA at one end the mating part 7 of the collar 3, and at the other end the locking part 8, which contains electrical and mechanical parts, and a spring-loaded latch is installed on the mating part 7 of the collar 9 with a fixing pin 10, with the possibility of moving along the curved notch 11 of the large gear 12, interacting with the small gear 13, connected by means of a worm 14, mounted on the shaft of the electric motor 15, which is electrically connected to the power source 16 and the system board located on the circuit board (not shown in the drawing) of the electrical part of the latch.

The control system (Fig. 7) of the dog’s muzzle electromechanical latch includes a microcontroller 17, the first input of which is connected to the output of the receiver 18, the second input is connected to the gear position sensor 19, the first output of the microcontroller 17 is connected to the indicating device 20, and the second output to the actuator is an electric motor 15 of the latch, while the microcontroller 17, the receiver 18 and the electric motor 15 are connected to a power source 16.

In order to close the lock, it is necessary to move the element 9 in the direction indicated in Figure 4. The spring-loaded part 9 of the latch will first enter the output of the figured cut-out 11 of the gear 12, and then, due to the beveled bevel of the pin 10, will jump over the edge of the figured cut-out of the gear 12. The fixing pin 10 will be at the very end of the figured cut-out of the gear 12. In Fig. 5, a sectional view is shown , how the locking pin will be located inside the curly cutout.

The lock will be closed, spontaneous opening is excluded by the springy properties of the element 9 and a special shape of the cutout of the element, in which there is an additional eccentric recess at the point of fixation of the pin (Fig.6).

The lock opening mechanism works as follows (Fig. 7): after the microcontroller 17 receives the opening signal, the electric motor 15 is turned on. The worm 14, mounted on its shaft, drives the small gear 13, which, in turn, transfers force to the large gear 12 The intermediate link in the gear transmission is necessary to increase the torque of the electric motor.

When the large gear 12 is rotated, the locking pin 10 will mix along its curly notch. As soon as the gear 12 completes a full revolution (360 °), the latch pin 10 will disengage and the lock halves will separate. Upon completion of a full revolution, the mechanical end switch SW1 closes - i.e. the gear position sensor 19 will work 12, the microcontroller 17 will stop the electric motor. The mechanism will be ready for a new snap cycle.

The design of the lock housing should provide the only possible position for connecting the lock components, as well as the straightness of the movement of the latch until the moment of engagement, while allowing the bending of the movable part of the latch 9 at the time of jumping of the ridges of the figured notch gear 12.

The device operation control algorithm is shown in Fig. 8.

For control, standard car alarm key fobs are used, working with keeloq standard signal encoding at a carrier frequency of 433.92 MHz. The reception range is provided by the capabilities of the key fob. To bind a specific key fob to a particular lock, the SW2 button is intended, after pressing which the electronic control circuit will wait for a while (for example, 15 seconds) to wait for a code signal from the key fob. After receiving the signal, the kit will bind. In standby mode, the microcontroller is in sleep mode. Once 0.5-1 s, it “wakes up” and connects the receiver. Over the next second, we accept everything that is on the air at the desired frequency, the microcontroller analyzes the received code. If the code is encrypted using a pre-recorded key fob, the microcontroller issues a signal (through the key transistor VT1) to the electric motor. The electric motor turns on and through the system of lowering gears opens the lock. At the time of full opening, the limit switch (sensor 19) is activated - the electric motor 15 stops. If there is a breakdown of the mechanism and the limit switch-sensor 19 does not close the set time - forcibly stop the drive after 10 seconds.

If microcontroller 17 does not receive the correct code, then after a second it “falls asleep” (timers, counters, receiver are turned off, the device goes into low power mode). This is necessary to save battery power.

The device is equipped with an LED indicator 20, the main role of which is to indicate a discharged battery of the power source 16. The indicator flashes synchronously with the inclusion of the microcontroller 17 in operation. If the battery voltage is below a predetermined threshold - the microcontroller 17 turns off the LED 20 - it is clear that it is time to change the battery.
