ABSTRACT:
CLAIM OF PRIORITY
This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. § 119 from my application VESA COVER SECURING STRUCTURE FOR LCD MONITOR filed with the Korean Industrial Property Office on May 1, 1999 and there duly assigned Serial No. 99-15767.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to LCD monitors, specifically to a VESA cover installed at the back of an LCD monitor.
2. Description of the Prior Art
Generally, a liquid crystal display (LCD) monitor is a device which displays images by applying a voltage to a liquid crystal to change the molecular structures thereof, thereby changing the optical characteristic of the liquid crystal. LCD monitors are installed on television sets, computers, video cameras and other devices in order to reduce the size of the device for portability, and to save electricity. In particular, the LCD monitors for computers and televisions have a small enough size to enable the monitor to be placed on a desk or be hung up on a wall. Such monitors normally have a handle hinged to a VESA (Video Electronics Standards Association) cover installed at the back of the monitor.
In a generally used LCD monitor, a square depression is formed at the rear middle portion of the rear cover of the LCD monitor. The VESA cover is installed on the square depression. At the four corners of the square depression, bosses protrude rearward. These bosses comprise cylindrical bodies, and a plurality of supporting members formed integrally with lower portions of bodies of the bodies. Insert members with screws formed therein are inserted into the inner peripheries of the bodies.
A plurality of through holes are formed on the four corners of the VESA cover. Therefore, when the VESA cover engages the square depression, a plurality of screws penetrates the through holes and engages the bosses so that the VESA cover engages the square depression of the rear cover.
However, when forming the LCD monitor, such a securing structure of the VESA cover is formed simultaneously with a plurality of bosses with the members inserted therein, complicating the manufacturing process and raising the cost for the production.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an improved VESA cover for a liquid crystal display monitor.
It is a further object of the present invention to provide a VESA cover which is less complicated to manufacture.
It is a still further object of the present invention to provide a VESA cover which does not require separate injection molded parts such as bosses.
It is a yet further object of the present invention to provide a VESA cover which is less expensive to manufacture.
The above and other objects, advantages and features of the present invention will become more readily appreciated and understood from a consideration of the following detailed description of a preferred embodiment of this invention when taken together with the accompanying drawings.
In order to achieve above objects, a securing structure of VESA cover of a LCD monitor according to the present invention comprises: a rear cover with a depression formed on a predetermined location of the rear surface, a plurality of first through holes formed at an indented portion of the depression; a VESA cover having a plurality of second through holes formed at locations corresponding to the first through holes, said second through holes engaging the depression of the rear cover; a shield placed at inner side of the rear cover, said shield having a plurality of third through holes at locations corresponding to the first and the second through holes; and a plurality of extended nuts inserted into the third holes of the shield, wherein a plurality of engaging screws penetrate the first and the second through holes and engaging the extended nuts so that said VESA cover is installed onto the squared depression of the rear cover.
Preferably, the extended nut has a cylindrical body and a screw thread formed on the inner periphery thereof, and a head portion protruding along the outer periphery of the body, and the body of said extended nuts is inserted into the through holes, securing the shield.
More preferably, the outer diameter of the body of the extended nut is larger than outer diameter of the third through hole so that said extended nut is contacting and expending the inner periphery of the third through hole when the extended nut is inserted into the through hole.
The securing structure for the VESA cover involves extended nuts engaging the VESA cover and the rear cover, facilitating the assembly process. Furthermore, since separate parts formed by injection molding are not needed, this reduces the product cost.
