Description

Technology area

The claimed utility model relates to door handles and can be used to open the doors of premises.

State of the art

Known door handle (patent RU 69126 U1 IPC E05B 1/00, Published: 10.12.2007, bull. No. 34), made of two symmetrical halves connected by a fastening unit, including a tie rod, and containing at least one gripping part, at least two holders of the gripping part and decorative covers, moreover, the holder of the gripping part is made in the form of a bracket, at one end of which there is a hole with a safety sleeve located in it, and at the other end - a supporting element with an opening for placing a fastening unit consisting of bushings with spherical heads , collars and threaded on the inner surface, connected by a tie rod, while a recess for the tool is made on the spherical head of one of the bushings, and knurling is made on the side surface of the other bushing, in addition, the gripping part of the door handle is made of a hollow profile and fixed in the bracket locking screw.

The disadvantage of the existing design of the door handle is its lack of hygienic characteristics.

The closest device in technical essence is a door handle (patent RU 2235840 C1, IPC E05B 1/00, Published: 09/10/2004, bull. No. 25), containing a handle with blind threaded holes, a handle with cavities, linings with holes and fastening products , moreover, the handles are placed on the pads and fixed to the last fasteners. Some of the fasteners, together with blind threaded holes, are fastened to the handle and plates, while other fasteners are located in the cavities of the other handle and fastened to one plate. This handle has increased stealing resistance.

The disadvantage of the existing door handle design is its lack of hygienic characteristics.

The proposed technical solution eliminates these disadvantages.

Disclosure of the utility model.

The technical result of the proposed utility model is the creation of a door handle with hygienic characteristics.

The specified technical result is achieved in the device a door handle with an antibacterial coating containing a handle with blind threaded holes, a handle with a cavity, linings with holes and fastening products, the handles are placed on the linings and fixed to the last fasteners, and the working surfaces of the sides of the handles contain copper material with antibacterial properties, while the antibacterial layer is made in the form of a web, woven of copper threads, and is placed on the outer surface when pressing transparent Tritan polyester around the working surfaces of the sides of the handles.

Distinctive features are:

the working surfaces of the sides of the handles contain copper material with antibacterial properties, which have hygienic characteristics;

the antibacterial layer is made in the form of a web, woven of copper threads, and placed on the outer surface when pressing transparent Tritan polyester around the working surfaces of the sides of the handles, which makes it possible to increase hygiene characteristics due to the use of a hypoallergenic transparent material that does not contain harmful chemical compounds, does not interact with others objects even when the temperature rises [3].

Comparative analysis of the features of the claimed solution with the features of the prototype and analogs indicates the compliance of the declared solution with the "novelty" criterion.

Brief Description of Drawings

The claimed utility model A door handle with an antibacterial coating is schematically shown in the Figure, containing: 1 and 2 handles; 3 and 4 overlays; 5, 6, 9 fasteners; 7 turnkey cavities; 8 and 10 threaded holes; 11 a secret cavity for fasteners, 12 copper threads of cloth, 13 and 14 working surfaces of the sides of the handles made of hypoallergenic material.

Implementation of the utility model

Pressing the working surfaces of the sides of the handles 1 and 2 for the implementation of the antibacterial effect is performed as follows.

Previously, a web woven of copper threads 12 is laid along the entire perimeter of the inner working part of the mold, touching the surface of the mold (not shown in the figure), and a metal handle 1 or 2 made according to the prototype is fixed inside the mold. Then hot pressing is carried out around the handles 1 and 2 of the working surfaces of the 13 and 14 sides of the handles, at a pressure of 70 - 120 kg / cm ² and a temperature of 170 - 200 ° С with transparent polyester - Tritan, which, as a hypoallergenic material, performs protective functions.

The operator, by touching his hand to the working surface of the handles 13 and 14 with the copper threads of the door leaf 12 of the door handle 1 or 2, opening the door, achieves antibacterial protection when using this device.

Tritan and copper help protect the surface of the doorknob from microbial flora during continuous use.
