Definitions

  • ABSTRACT This invention provides an enclosure in which the principle structural support is provided by a pair of generally horizontal sheet metal planes separated by a central column with each of the members being formed of a continuous piece of sheet metal. The central column cooperates with the top and bottom structural members, not only to support, but to provide alignment and gauging functions and may further simultaneously provide for shielding, compartmentalization and ducting functions. The enclosure is completed by top and side covers supported from the principle structural elements.
  • the principle structural support for an enclosure is provided by a pair of sheet metal planes interconnected by a column of formed sheet metal.
  • the top and bottom planes are formed with a longitudinal channel, the flange portions of which form attachment surfaces.
  • the column member is formed with longitudinally extending terminal flange portions with the upper and lower margins abutting the top and bottom channel flange surfaces and secured thereto to initially provide transverse alignment and thereafter afford interconnection.
  • the column is formed with the marginal edge surfaces of the sheet portions transversely interconnecting or extending from the longitudinally extending column wall portions engaging the vlower surface of the web of the top channel and the upper surface of the web of the bottom channel to gauge the vertical spacing between top and bottom planes.
  • the column member provides design flexibility in affording not only 'the principle support, but also enabling simultaneous provision for isolating various portions of the resulting enclosure. Such isolation may effect electromagnetic'or acoustic shielding of various portions of the enclosed space one. from the other or provide ducting for fluidsuch as cooling air or vacuum supply. In the latter instance, the resulting closed column provides added torsional resistance between top and bottom planes. Where cooling is required pressurizing a closed section of the central column to afford a static head provides a plenum structure fromwhich flexibility in size and configuration to meet application requirements withoutthe employment of special tooling.
  • the enclosure may be completed by installing fixed I end plates and hinged front and rear cover sections.
  • a louvered door section can be generated by the use of a perforate sheet. extending between the netically shield discrete portions within the enclosure. It is also a function of the invention to provide an enclosure wherein the principle structural parts are self aligning and self gauging.
  • FIG. 5 is an interrupted partial vertical section view of the enclosure taken along line 5-5 of FIG. 3 illustrating the attachment ofa hinged cover member.
  • FIG. 6 is an isometric view partially broken away of a louvered cover member.
  • FIG. 7 is an isometric view of a bracket that forms a portion of the upper hinge structure of FIG. 5.
  • FIG. 8 is an exploded isometric view of a bracket and cooperating apertured channel portion which forms a part of the lowerhinge structure of FIG. 5.
  • Top member lo is formed of a continuous sheet of metal with a central longitudinally extending channel 14 upper and lower angle elements that form a portion of between and secured to such angle elements.
  • the louver sections each have a flange secured along the surface of the perforate sheet and present an external the cover with vertical louver-sections extending requiring no special tooling.
  • 'It is a further object of this 1 enclosure wherein the structural elements may also flexibly function to compartmentalize and electromag downwardly depressed from the upper surface which includes a central web portion 15 and attachment flange portions 16.
  • a downwardly turned flange 19 along each of the-transverse margins provides structural rigidity and also a surface for the attachment of other enclosure components.
  • the bottom member 1 1 is similarto top member 10, having a longitudinally extending central channel 22 projecting upwardly from the lower surface. Channel 22 presents a pair of parallel attachmentv flanges 23 and a connecting web 25.
  • the bottom member also provides a turned flange 27 along each transverse marginal edge' for attachment and structural rigiditypurposes.
  • An end plate 29 is attached at each longitudinal end of top member 10 by being welded to the abutting marginal edge surface.
  • end plates 31 have lowerplanner portions 32 welded to the edge surfaces along the longitudinal ends of the bottom member 11 with each of such plates presenting an upper portion 33 diverging upwardly and outwardly.
  • Central column element 12 is formed of a single continuous sheet of metal with longitudinal wall portions 36 connected by cross members 37 and a final terminal flange 38 welded to the adjoining longitudinal wall portion. In constructions requiring a complex central columnelement, it may be. more economical to fabricate such column of two or more piecesto achieve the required alignment and parallelism and avoid problems of handling large sheets.
  • the column element longitudinal wall portions 36 present alignment flanges 40 which project upwardly and downwardly respectively along the surfaces of the top and bottom member channel attachment flanges 16 and 23. These flanges 40 terminate before they reach the top and bottom member surfaces respectively.
  • the cross member of upper marginal edge surfaces 42 abut the lower surface of the channel web of top member and the lower cross member edge surfaces 43 abut the upper surface of the bottom member channel web 25.
  • Each of the principle structural members, top member 10, bottom member 11 and central column element 12 are each formed of a single, continuous sheet of metal which require, as necessary tooling, only a press brake.
  • the length and width of the top member and the bottom member can be varied according to the design requirements while the height of the overall structure may be varied by changing only the width of the sheet used to form center column element 12.
  • FIG. 3 shows an isometric exterior view to which a top cover 46, and covers 47, hinged doors 48, 49 and kickstrips 50 have been attached.
  • the end covers 47 are secured as shown in FIG. 4 with the lower marginal portion 51 turned back on itself and formed into a curved channel in which is received the longitudinal margin of the diverging portion 33 of lower end plate 31.
  • the upper margin of the end cover 47 is flanged to present a surface 54 in abutting contact with the exterior major surface of the top member end plate 29.
  • the end cover 47 is configured so that in cooperation with the bottom member end plate 31 and the top member end plate 29 a vertical surface 55 is presented which is co-planar with the end surface 56 of top cover 46.
  • the kickstrip 50 is fabricated of formed sheet metal with a securing strip 58 projecting therefrom and held captive against the lower surface of bottom member 11 by a series of spring clips 60.
  • Hinged covers 48, 49 are pivotally connected to the top member 10 and bottom member 1 1 about a vertical axis as shown in FIG. 5.
  • the top cover 46 is secured over top member 10 and presents a planar top surface 62 to the completed enclosure and a series of vertical surfaces 63 adjoining the margins thereof which are coplanar with the adjoining end cover or hinged cover.
  • the cover is formed of a shrouding sheet metal portion 65 which provides the major external surfaces 66 and extends between an upper angle 68 and a lower angle 69.
  • An upper bracket 71 shown in FIGS. 5 and 7 which includes a horizontal portion 72 with an aperture 73 and a turned tab 74 is secured to the top member flange 19 by welding the tab in abutting relation with such top member flange.
