Description

Screen lens protector and its manufacturing method {A PROTECT FILTER WITH SCREEN LENS AND METHOD OF MANUFACTURE THEREOF}

The present invention relates to a screen lens protector and a manufacturing method thereof, and more particularly, to a screen lens protector and a method of manufacturing the same that can be used by a computer as if a person with low vision wears glasses or contact lenses without wearing glasses or contact lenses. will be.

Today, as computers become more prevalent, computers are being used in everything from office work to everyday household chores. Accordingly, the time for using a computer is increasing and various kinds of monitor security devices for blocking electromagnetic waves emitted from the monitor of the computer have been released. Since these monitor security devices are designed for people with normal vision, people who wear glasses use their computers while wearing glasses. In order to alleviate this inconvenience, conventionally, a monitor expansion security device for using a computer without using a separate magnifying glass or glasses has been disclosed.

Hereinafter, the prior art will be described in detail with reference to the prior art.

Republic of Korea Patent Publication No. 2005-0109768 (hereinafter referred to as 'prior art')

The prior art relates to a monitor magnification security device including a planar magnification lens, and according to Lines 25 to 27 of the Patent Publication, "The present invention is to solve the above problems, a planar magnification lens including an electromagnetic wave blocking function. Its purpose is to allow you to use the monitor for a long time without burdening your eyes without using extra glasses. It is an object of the present invention to provide a monitor magnification security device equipped with a flat magnification lens so that a monitor can be used for a long time without using glasses.

In order to achieve this purpose, the prior art monitor magnification security device, as shown in Figs. 1 and 2, a planar magnification lens 13 and the planar magnification lens 13 of substantially the same size as the monitor 40 screen. The lens unit 10 including the frame 11, 12 for supporting the bracket, the bracket 34 is fixed to the upper surface of the monitor 40 and the upper portion of the bracket 34 is mounted so as to be backward A distance adjusting unit 30 including at least one guide bar 31 to adjust the focus of the planar magnifying lens 13, a rotation protrusion 21 formed on the lens unit 10, and the It is composed of a rotating part 20 surrounding the rotating protrusion 21 and including a rotating protrusion cover 22 connected to the front end of the guide bar 31.

The monitor magnification security device of the related art having the above configuration has the advantage that it can be conveniently used to focus the monitor screen without a separate magnifying glass or glasses, but the frames 11 and 12 equipped with the planar magnifying lens 13 are provided. Guide bar 31, guide bar width lock 32, guide bar lock 33, bracket 34, bracket and guide bar lock to adjust the distance between the monitor and the monitor 40 Frames 11 and 12 for fixing the distance adjusting unit 30 including the 35 and the like, the rotating unit 21 including the rotating protrusions 21 and the rotating protrusion cover 22, and the planar magnifying lens 13. Because of the need for such a configuration, there is a problem in that the composition of the product is complicated and the manufacturing cost increases.

In addition, when a monitor magnification security device is installed on a computer monitor, the distance between the monitor 11 and the frames 11 and 12 on which the planar magnification lens 13 is mounted is not so good for aesthetic appearance. There was an uncomfortable issue.

In addition, as the computer monitor gradually changes to the LCD screen, the thickness of the monitor becomes thinner and the heat sink structure for dissipating heat inside the monitor is integrally formed on the upper part of the monitor, thereby making it difficult to fix the bracket 34 on the upper part of the monitor. Instead, even when the bracket 34 is installed, the bracket 34 fixed by adhesion has a problem of frequently falling off due to the weight of the security device.

In addition, the planar magnification lens 13 according to the related art is a planar magnification lens that simply magnifies the size of the monitor screen, and the shape of the pattern is defined as one, so that the user can mount the frame 11 on which the magnification lens 13 is mounted. The font and sharpness of the screen had to be adjusted while adjusting the distance between the 12 and the monitor 40. However, since the conventional planar magnifying lens 13 only functions to enlarge the screen like a kind of magnifying glass, it is impossible to adjust the font and sharpness of the screen suitable for one's eyesight.

In addition, since the computer monitor is used by tilting back and forth with respect to the vertical plane in accordance with the eye level of the user, even if the distance between the planar magnifying lens 13 and the monitor 40 is installed horizontally, the plane is tilted by the tilt of the monitor. Since the lower end of the magnifying lens 13 moves, there is a problem in that it cannot function properly.
