The subject invention relates to an assembly for mounting a display screen supported by a chassis to a front panel which is supported by support structure such as a rack, or the like.
Numerous systems are known in the prior art for mounting display screens. Some of the most widely known are those for mounting the cathode ray tubes of televisions sets. Such systems are infrequently dismantled whereas assemblies used in electronic environments are frequently accessed for various reasons. Examples of such prior art assemblies are shown in U.S. Pat. Nos. 4,017,129 to Boldt et al., U.S. Pat. No. 4,063,289 to Veenendaal, U.S. Pat. No. 4,593,227 to Bruce et al., U.S. Pat. No. 4,644,408 to Coleman U.S. Pat. No. 5,351,176 to Smith et al., U.S. Pat. No. 5,661,630 to Levins et al., U.S. Pat. No. 5,682,300 to Sung and U.S. Pat. No. 5,699,132 to Adachi et al.
However, there remains a need for a simple assembly which is easily fabricated and wherein the chassis portion is easily assembled and disassembled to a front panel which remains attached to a support structure, such as a rack.
A front mounted chassis assembly for a display screen. The assembly includes a front panel for being supported on a support structure and a wall presenting an interior surface extending rearwardly of said front panel to present an open periphery. A plurality of tabs extend transverse to the wall. A chassis for supporting a display screen includes a plate and fasteners extend through the plate to engage the tabs to support the chassis on the front panel, the display screen projecting forwardly of the plate and into the open periphery of the wall to the panel. The assembly is characterized by reinforcing flanges extending inwardly about the periphery of the wall to reinforce the wall.
Other advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein FIG. 1 is an exploded perspective view of the subject invention.
Referring to the FIGURE, wherein like numerals indicate like or corresponding parts throughout the several views, a front mounted chassis assembly for a display screen is generally shown at 10.
The assembly comprises a front panel 12 for being supported on a support structure, such as a rack, and a chassis, generally indicated at 14, for supporting a display screen 15.
A wall 16 presents an interior surface 18 extending rearwardly of the front panel 12. A plurality of tabs 20 extend transversely to the wall 16. More specifically, the wall 16 has four sides to define four corners and one of the tabs 30 is disposed at each of the corners. Each tab extends laterally inward from the sides of the wall 16 but next adjacent the top and bottom sides of the wall 16.
The chassis 14 includes a plate 22. A plurality of threaded fasteners 24 extend through the plate 22 to engage the tabs 20 to support the chassis 14 on the front panel 12.
The assembly is characterized by reinforcing flanges 26 extending transversely to and inwardly about the periphery of the wall 16 to reinforce the wall 16. The plate 22 also has a four sided periphery to present four corners and is of the same general size to fit snugly within the periphery of the wall 16.
In addition, the plate 22 and the flange 26 include a plurality of cut-outs 28 and 30 respectively extending therethrough for allowing an electrical lead 32 to pass therethrough or to accommodate projections on the interior surface 18 of the wall 16.
The wall 16 and the plate 22 are made of metal and each of the tabs 20 includes threads. Each of the fasteners 24 is threaded for threadedly engaging the threads of the tabs 20. Each of the tabs 20 is integral with the flange 26. However, the flange 26 comprises bent over portions from the wall 16, i.e., the top and bottom flange portions are integral with the top and bottom sections of the wall 16 and include the tabs 20 whereas the side flange portions are integral with the side sections of the wall 16.
The chassis 14 includes a housing extending rearwardly from the plate 22 and which includes a front 34, a right side 36, a left side 38 and a bottom tray 40. The bottom tray 40 is positioned vertically part way up the sides 36 and 38 of the housing. The front panel 12 has a larger periphery than the four sided wall 16 and the plate 22 has a larger periphery than the front 34 of the housing so as to extend radially outwardly of the housing. A front wall 42 extends about the periphery of the side walls 16 and defines an opening therein for viewing the display screen, which is supported by the plate 22 and extends forwardly of the plate 22 for engaging the panel 12. The panel 12 is opaque for viewing the display screen 15.
A cooling fan 44 is supported by the housing and at least one circuit board 46 is supported on the bottom tray 40 of the housing.
The invention has been described in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, wherein reference numerals are merely for convenience and are not to be in any way limiting, the invention may practiced otherwise than as specifically described.
