A PROTECTIVE SCREEN FRAME STRUCTURE
The present invention relates to a protective screen frame structure in which the protective screen can be freely pivoted upward to an inclined position above the screen of a television or computer monitor for easily clearing the dust thereon. Also, the inner face of the protective screen facing the screen of the television or monitor can be easily wiped and cleaned. The fixing plates of the protective screen can be also rotated according to the shape and curvature of the top face of the television or monitor so as to be snugly attached thereto.
A protective screen is positioned in front of the screen of a television of a computer monitor for stopping the radiation from being radiated into human eyes. The conventional protective screen 13 is disposed in such a manner that a double-face adhesive paper 12 is attached to a back face of the protective screen for fixing the same on the television or the monitor 11 in front of the screen thereof as shown in Fig 1. According to such arrangement, several shortcomings exist as follows:
1. After attached to and fixed on the television or monitor, the protecive screen cannot be easily removed. Therefore, in the case that the screen of the television or the monitor or the protective screen itself is contaminated by dust after a period of use, the protective screen cannot be easily detached from the television or monitor for cleaning.
2. The top face of the television or monitor is usually not a plane face and has a curvature, so that the protective screen often cannot be snugly fixed thereon.
Therefore, it is necessary to provide an improved protective screen frame structure which enables the protective screen to be easily removably and snugly fixed on the top face of the television or the computer monitor.
It is therefore a primary object of the present invention to provide a protective screen frame structure in which the protective screen can be freely pivoted upward to an inclined position above the screen of a television or computer monitor for easily clearing the dust thereon.
