Description

The technical solution relates to the terminal equipment of users with mobile radio transceivers (radiotelephones, mobile phones, cordless radiotelephones, radio extension cords, etc.) and can be used to shield devices and their parts to protect a person from electromagnetic radiation.

Shielding devices against electromagnetic radiation from mobile radio communications have been patented in various countries since the ubiquity of mobile phones. In the 90s of the last century, the main attention was paid to screening the design of telephones with protruding (retractable) antennas. (see; for example, patents: RU (DE) 2192717 C2, 11/10/2002 [8]; GB 2330726 A, 04/28/1999 [7]; JP 4220851 A, 08/11/1992 [6]; US 5338896 A, 16/08/1994; US 5367309 A, 11.22.1994; US 5787340 A, 07.28.1998). With the improvement of radio facilities, including mobile phones, and the placement of the antenna in their case, the subject of improvement is covers, cases, bags for carrying phones and shielding materials in their manufacture. Recently, materials and fabrics shielding from radiation exposure have been patented: RU 2102801 C1, 01.20.1998 [11]; RU 2198442 C2, 02/10/2003; RU 2229544 C1, 05.27.2004; RU 84022 U1, 06/27/2009; FR 2745690 A1, 09/12/1997; WO 2010/024718 A1, 03/04/2010 and others.

Analysis of known devices for placing and carrying (wearing) mobile phones shows that when considering their design, insufficient attention is paid directly to shielding materials [3-5] and vice versa: when describing shielding materials, the design features of handbags-cases and cases are not considered, see, for example [11] WO 2010/024718 et al.

This is a disadvantage of the known devices, because for adequate industrial use it is necessary to consider in a single device a combination of all the features, including the design of cases, bag-cases and applied shielding materials, providing a synergistic technical result when using the device.

So, handbags [4, 5] for the phone only declaratively describe the shielding material without giving its properties, the device [3] gives a general description of the flag without affecting the design features of the screen, the information about the case [2] for the mobile phone also does not specify the characteristics of the reflecting material. In addition, radiation protection when using devices [2-5] is provided only when worn, i.e. the negative impact of electromagnetic waves on a person persists during conversations (especially frequent and lengthy) of the user over the phone.

Reducing the time of the negative effects of radiation on a person during a conversation provides a protective device [1] for users of cordless phones.

The protective device according to the patent RU 14750 U1, 08.20.2000, adopted as a prototype, includes a housing, the front wall of which, facing the human body, is equipped with a protective screen containing material that attenuates electromagnetic radiation, with holes for the phone and microphone on the front wall . The housing of the device [1] contains a protective screen, which is made with the possibility of vertical movement along the longitudinal grooves of the side walls of the housing and on the inner surface of which is shielded radiation material.

However, the execution of the screen (cover) of the case, moved in grooves, due to the presence of a retractable antenna in the phone, complicates the design and adequate use for the intended purpose, reducing, accordingly, the reliability of protection, which limits the functionality of the device [1]. In addition, as in other analogues [2-5], in [1] the protective screen is not described, the characteristics of the shielding material are not given, the type of material is not defined, which allows to refer the known device [1] (like devices [2-5 ]) to the category of hypothetical, very limited in industrial implementation.

The essence of the proposed technical solution is to create a protective device “SCREEN” (special name) for users of mobile radio transceivers, which allows to minimize the time of negative impact on a person (both when wearing a phone or when talking on a call) when used as a protective a screen of a conductive fabric of the Metacron type, which has an optimal compromise between the characteristics: high elasticity, high conductivity and relatively low cost.

The main technical result of the proposed device is the provision of reliable protection of the mobile phone user from the influence of electromagnetic wave radiation while reducing the time of the negative effect of radiation during a call by the subscriber by using “Metacron” fabric as a radiation attenuating material, the properties of which allow for relative simplicity manufacturing and application to practically achieve high radiation absorption characteristics.

The technical result is achieved as follows.

The protective device for users of mobile radio transceivers includes a housing, the front wall of which, facing the human body, is equipped with a protective screen containing material that attenuates electromagnetic radiation, while the front wall has holes for the telephone and microphone.

In one embodiment, a distinctive feature of the device is that the casing is made in the form of a case with a lid opening along scoring lines separating the front and back walls of the casing, the casing lid is provided on the inside with a pocket for embedding a protective shield containing material that attenuates electromagnetic radiation made from an electrically conductive fabric of the Metacron type with a structure of synthetic and metallized in several layers of fibers.

In this case, the lid on the side opposite to the scoring is provided with a latch for fixing on the case when it is closed, for example, with a textile velcro or a magnetic fastener.

In another embodiment of the device, the housing is made in the form of a bag-case with an upper open end wall, and at least one side wall of the bag-case on the inside is equipped with a pocket for embedding a protective screen containing material that attenuates electromagnetic radiation made of an electrically conductive fabric of the type "Metacron" with a structure of synthetic and metallized in several layers of fibers.

In addition, the difference between the protective device is that the pocket for the insertion of the protective screen containing the shielding material is equipped with a valve which is capable of being fixed, for example with a textile velcro.

The drawing shows a general structural diagram of the proposed protective device "SCREEN" (EKRAN), - an embodiment in the form of a case with a hinged lid, - where the following notation is used:

1 - mobile phone;

2 - case;

3 - cover;

4 - the front wall of the housing;

5 - the back wall of the housing;

6 - a protective screen;

7 - holes for the phone;

8 - holes for the microphone;

9 - scoring lines;

10 - pocket;

11 - latch.

The use of the device can be illustrated by the following example.

To dial a number, the user opens (flips) the cover 3 of the housing 2 to the "open" position. The cover 3 is folded (folded down) along the scoring lines 9. This opens the display and keypad of mobile phone 1. When dialing a number and recalling the dialed subscriber, cover 3 returns to its initial “closed” position and is secured to the housing 2 by a latch 11. The user is talked with the cover 3 closed through openings 7 for the telephone and openings 8 for microphone on the front wall 4 of the housing (cover). In this case, the radiating elements of the telephone 1 are closed from a person by a protective screen 6 placed in the pocket 10. The idle telephone 1 is worn with the front wall 4 facing the human body.

Using the second variant of the device in the form of a handbag-case is carried out in a similar way, while the phone is inserted into the handbag-case with the display and keyboard in the direction of the protective screen located in the pocket of the handbag-case.

An electrically conductive fabric of the Metacron type [10, 11] with a structure of synthetic and metallized layers, used as a material for a protective shield that attenuates electromagnetic radiation, in comparison with the well-known materials Voskhod (RU 2229544 C1, 05.27.2004), Velcro "[7], as well as with well-known materials according to patents FR 2745690 A1, 09/12/1997; RU 84022 U1, 06/27/2009; WO 2010/024718 A1, 03/04/2010 in the form of a metallized mesh, shows higher radiation reduction characteristics. The general structure of the Metacron fabric and its production technology are described in [11] and comply with sanitary-epidemiological and hygienic requirements [10]. The Metacron fabric has a new optimal synergy of characteristics: high elasticity, high conductivity and relatively low cost.

Tests conducted in 2011 confirmed the high performance of the SCREEN device for protection against electromagnetic radiation (see table).
