Description

Technical field

The claimed device relates to a leash for walking animals with a mechanism for winding and unwinding the leash.

State of the art

A roulette-leash device is known (Patent RU 2745688 C2, 06/21/2019 IPC A01K27 / 00, published on 03/30/2021 Bull. No. 10) The described roulette leash has a body with a handle and a mechanism for winding and unwinding the leash. A mechanism is provided in the body which exerts a restoring force on the leader so that, as soon as it is at least partially unwound and no tension force is exerted on the leader, it automatically retracts into the body and winds up here.

The disadvantage of the tape measure-leash is the lack of antibacterial properties.

The closest roulette-leash device is known (Patent US 93399014 B1, IPC A01K27/004 Published: 05/17/2016), containing a leash, a coil, a user-controlled brake, in which the braking action created by the brake slows down with a gradually increasing speed the payment of the leash from the body leash to help prevent undue discomfort and injury to the pet using the leash.

The disadvantage of the device roulette-leash is the lack of hygienic characteristics.

The proposed technical solution allows to eliminate these shortcomings.

Utility Model Disclosure

The technical result of the proposed utility model is the creation of a leash with an antibacterial coating, which has hygienic characteristics.

The specified technical result is achieved in an antibacterial leash-roulette device containing a plastic handle and a body with a mechanism for winding and unwinding a leash for walking animals, moreover, the plastic surfaces of the handle and body contain titanium material with antibacterial properties, while the titanium material with antibacterial properties is made in in the form of spraying on the outer surface of the handle and body around the working surfaces.

The hallmarks are

plastic surfaces of the handle and body contain titanium material with antibacterial properties, creating a hygienic protection;

titanium material, with antibacterial properties, is made in the form of spraying on the outer surface of the handle and body around the working surfaces, creating a hygienic antibacterial protection.

Comparative analysis of the features of the proposed solution with the features of the prototype and analogues indicates that the proposed solution meets the criterion of "novelty".

Brief description of the drawings

The claimed roulette-leash device with an antibacterial coating is schematically shown in Fig. 1 in the form of a frontal view, including: 1 - tape measure-leash, 2 - handle, 3 - body, 4 - leash, 5 - outlet, 6 - locking mechanism, if necessary, activated by the owner by means of a push button, 7 - middle axis, 8 - axis of rotation,

in fig. 2 shows a local section A-A in Fig. 1, including: 9 - titanium coating, 2 - handle.

Implementation of the utility model

Titanium coating 9 is applied to the plastic case 3 and the handle 2 to create an antibacterial effect, which is performed as follows.

Titanium particles are placed in a heated flow of nitrogen or helium, which expands through a converging-divergent nozzle, the process of cold spraying imparts supersonic speeds to titanium particles [3]. The powder supply is introduced at high pressure at the nozzle inlet and is fed from the nozzle onto a rotating plastic housing 3 with a handle 2. The particles trapped in the gas are directed towards the plastic surface at a temperature of 100-500°C of the expanded gas flow exiting the nozzle, they are embedded upon impact, forming a strong bond with the plastic surface of the body 3 and handle 2, forming a titanium coating 9.

Titanium sputtering 9, presented in the form of titanium powder raw materials, is applied with a thickness of 10 μm, and creates an effective antibacterial protection [4].

The user, by touching the working surface of the body 3 and the handle 2 with titanium coating 9 of the tape measure-leash 1, achieves antibacterial protection when using this device.

Titanium coating allows you to protect the surface of the tape measure-leash from microbial flora with its constant use.
