Safety goggles for display device with side pressing fixing structure

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety goggle for a display device having a side fixing structure. In particular, when fixing a frame for supporting a filter to a display device, both sides of the display device are fixed by pressing without using an adhesive and applied to various display devices. Corresponding to a safety goggle for a display device having a side fixing structure that can be easily made up and down height adjustment of the goggles body.

In general, desktop type computer monitors use cathode ray tube (CRT) as a display device because they are cheaper and have higher resolution than flat panel displays such as TFT LCD or VFD displays. It is required to install safety glasses to block harmful waves such as electromagnetic waves that are harmful to the human body.

In general, a user who uses a computer monitor at a distance closer than a TV viewer who is viewing at a distance is in an environment where they are working for a long time while being in close proximity to the monitor, so that infertility due to electromagnetic waves emitted from the monitor, VDT syndrome, or skin caused by static electricity Damage, and vision damage by strong light.

Therefore, the conventional safety glasses for blocking the harmful environment is composed of a conductive film for shielding electromagnetic waves on the surface of the base material, an optical coating film consisting of a plurality of anti-reflective layers, anti-pollution film to improve the adhesion phenomenon of foreign matter, etc. It consists of the filter which coat | covered the coating film, the rectangular frame which supports a filter, and the fixing apparatus for attaching a frame to a monitor.

In this case, the frame is made of a metal or plastic material such as Al in consideration of the material of the filter made of glass, plastic, such as polycarbonate or acrylic, and also suitable fixing device is used according to the structure of the frame used.

In general, all conventional fixing devices have a structure in which the fixing part is fixed to the upper surface of the monitor by an adhesive or the like, and the fixing part and the upper end of the frame are interconnected by flexible or insoluble connecting parts.

However, conventionally, when the main body is made of a heavy-weight structure as a glass filter and a metal frame, the adhesive strength of the adhesive for attaching the fixing part is reduced when a long time passes or the ambient temperature rises in the summer, so that the fixing part is peeled off the upper surface of the monitor. Problem occurs.

In addition, once such peeling occurs, replacement of the fixing unit may not be easily performed, and furthermore, there is a problem in that the upper surface of the monitor is easily burned due to the adhesive component remaining on the adhesive. Therefore, most of the users, once the peeling phenomenon of the fixing part occurs, using the adhesive tape having a good adhesion to attach the fixing part to the upper housing of the monitor. As a result, the appearance of the upper surface of the monitor is greatly reduced, and dust is attached to the edges of the adhesive tape, requiring frequent cleaning.

In general, since the distance to the upper end of the display screen of the monitor is not constant according to the manufacturer, it is preferable that the fixing device has a structure in which the main body is adjusted up and down so that the filter portion matches the display screen of the monitor.

However, in the related art, in this case, not only the structure of the fixing part is complicated, but also the upper and lower heights are not easily adjusted, and in addition, the size thereof is increased, and thus there is a problem in that it does not harmonize with the monitor body.

On the other hand, most of the current cathode ray tube for the monitor does not form a complete flat plate, and as a result, the upper and lower housing portions surrounding the cathode ray tube also form a curved surface protruding from the center.

By the way, in the conventional frame, especially when it consists of metal, the eye shield main body has comprised the flat plate shape as a whole. Therefore, when such a flat-type safety glasses body is mounted on the monitor, only the center portion of the upper and lower frames of the safety glasses contact a portion of the upper and lower curved surfaces of the monitor housing, and the remaining portion of the frame does not come into contact with the front surface of the housing of the monitor.

As a result, foreign matter, such as dust, is introduced into the filter through the space between the monitor housing and the safety glasses frame, so that the resolution of the filter and the monitor falls.

Therefore, the user is inconvenient to sweep the bottom of the filter up and periodically clean the display screen of the monitor and the inner surface of the filter. In particular, since the static electricity induced by the influence of the high-voltage current of the monitor is formed on the monitor display screen and the filter, there is a problem that acts as a suction force of the charged dust. Therefore, in order to prevent this phenomenon, it is desirable to block the contact of the dust on the monitor display screen and the inner surface of the filter.

Accordingly, the present invention has been made in view of the problems of the prior art, and its purpose is to fix both sides of the display device by pressing without using an adhesive when fixing the filter support frame to the display device, and at the same time various display devices. In accordance with the present invention to provide a safety glasses for a display device having a side fixing structure that can be easily made up and down height adjustment of the safety glasses body.

Another object of the present invention is to design the inner surface of the frame to have a profile corresponding to the front profile of the monitor housing and at the same time the entire frame is pressed on the monitor housing according to the fixing of the frame so that foreign matter is introduced between the filter and the display screen of the monitor It is to provide a safety glasses for a display device that can prevent the degradation of the resolution by blocking the thing.
