Title: Display screen chassis front mounting

Description:
TECHNICAL FIELD 
     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. 
     BACKGROUND OF THE INVENTION 
     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. 
     SUMMARY OF THE INVENTION 
     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. 
    
    
     BRIEF DESCRIPTION OF THE DRAWING 
     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. 
    
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     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.
