Title: Tandem merchandise display equipment
Claims: I claim: 1. A knockdown frame for supporting merchandise display and housing equipment, comprising (a) a pair of laterally spaced transverse beams of channel cross-section on the same level adjacent the lower end of the frame, with the flanges of said channels extending downwardly, (b) a vertical strut of channel form affixed to the downwardly facing flanges of each of said beams with the flanges of the channel of said strut extending outwardly, (c) a second pair of laterally transverse beams of channel cross-section on the same level at the upper end of the frame and overlying said first pair of transverse beams, the flanges of the second pair of channels extending downwardly, (d) means for joining the upper end of said vertical strut to the downwardly facing flanges of said second pair of beams, (e) a channeled lug welded to the lower end of each strut and projecting in a longitudinal direction from each of said first-mentioned downwardly facing flanges, with the web of the lug uppermost and its inner portion having a rectangular recess adapted to embrace said strut, and the inner edges of said web welded to the respective flanges of said first-mentioned transverse beams, and (f) a longitudinal beam of channel cross-section with the flanges extending downwardly between said channeled lugs and with the ends thereof disposed in superposed relation to said lugs and having a rectangular recess in the outer ends for embracing each vertical strut as well as openings in proximity thereto in alignment with corresponding openings in the webs of the lugs for receiving detachable interconnecting fastening means therebetween. 2. A knockdown frame as in claim 1, including an upper longitudinal beam extending between said second pair of transverse beams. 3. A knockdown frame as set forth in claim 2, including channel structural members for detachably connecting said last-mentioned upper longitudinal beam to said second pair of transverse beams, comprising (a) a second channeled lug with the web thereof welded to the top of said upper beam and projecting inwardly therefrom, (b) means for interconnecting each of said last-mentioned lugs with the adjacent transverse beam and vertical strut, and (c) cooperating fastening means adjacent to the ends of said upper longitudinal beam and said projecting portions of said last-mentioned lugs. 4. A frame as set forth in claim 3, wherein said upper longitudinal beam has a wider web than that of said last-mentioned lugs so that the latter are nested within the former at their junctures. 5. A knockdown frame for supporting merchandise display and housing equipment, comprising (a) a pair of laterally spaced transverse beams of channel cross-section on the same level adjacent the lower end of the frame, with the flanges of said channels extending downwardly, (b) a vertical strut of channel form affixed to the downwardly facing flanges of each of said beams with the flanges of the channel of said strut extending outwardly, (c) a second pair of laterally spaced transverse beams of channel cross-section on the same level at the upper end of the frame and overlying said first pair of transverse beams, the flanges of the second pair of channels extending downwardly, (d) means for joining the upper end of said vertical strut to the downwardly facing flanges of said second pair of beams, (e) channeled lugs affixed to the lower end of each strut and to the flange of the beam adjacent thereto, (f) a longitudinal beam of channel cross-section with downwardly extending flanges connected between said first-mentioned spaced beams and having the opposite ends thereof supported by and affixed to said lugs, and (g) a second longitudinal beam overlying said first-mentioned longitudinal beam and connected between said second pair of transverse beams and the upper ends of said vertical struts.
