Knock-down support base for merchandise display rack

DETAILED DESCRIPTION Referring to the drawings in detail wherein like numerals designate like parts, a knock-down support base for a display rack comprises a pair of equal length elongated base sections 10 and 11 which are horizontally disposed in use and provided at their opposite ends with conventional adjustable leveling feet 12.
The two base sections 10 and 11 are constructed of sturdy plate stock and, in use, the plate sections are disposed vertically for maximum rigidity.
The base section 10 comprises two plate sections 13 and 14 whose inner ends are welded as at 15 to the lower end portion of a relatively short vertical open ended sleeve 16 which extends substantially above the tops of the two plate sections 13 and 14.
A gap or notch 17 is provided at the bottom of the sleeve 16 between the plate sections 13 and 14 of base section 10.
A threaded nut 18 is welded to the exterior of sleeve 16 somewhat above the two plate sections 13 and 14.
Similarly, base section 11 comprises two plate sections 19 and 20 between which a second vertical sleeve 21 is disposed having its lower end portion welded as at 22 to the interior ends of plates 19 and 20.
A clearance space or notch 23 is provided in the base section 11 on opposite sides of the sleeve 21 and above the welds 22 in order to accommodate the sleeve 16, FIG.

The sleeve 21 has a radial aperture 24 formed through its side wall above the plates 19 and 20 adapted for alignment with the threaded aperture of nut 18 and a registering aperture 25 in sleeve 16.
When the support base is assembled for use, the two base sections 10 are arranged in right angular crossing relationship, FIG.

The larger diameter sleeve 16 is slipped over the projecting end portion of the smaller sleeve 21 telescopically with the bottom end of sleeve 16 seating solidly at the bottom of notch 23, as best shown in FIG.

This seating will place the nut aperture in registration with the two unthreaded apertures 24 and 25 of the two sleeves
