Abstract: In a soft drink merchandising gondola, a base shelf is convertible from a horizontal to a forwardly or rearwardly inclined condition by a reversible adapter interposable between the base shelf and a base shelf support. The adapter comprises a pair of wedges and a brace, and can be taken down, reassembled in compact form, and stowed underneath the base shelf when the base shelf is horizontal. The brace engages the elements of the base shelf support, to prevent horizontal movement of the brace along the direction of its length. Each wedge-shaped element has a split tab, receivable in either of two slots in the upper surface of a base shelf support element, and accessible by a screwdriver from the side of the base for spreading the tab elements to lock the tab in its slot.

Abstract: In an article of furniture, a captive nut base adjustment device is used for height and leveling adjustment. The device comprises a C-shaped retainer for captively holding a nut in contact with a horizontal flange of a base beam attached to the article of furniture. The nut receives a threaded shank of an adjustable foot. The shank extends through aligned holes in the flange and the retainer. The retainer and base beam include a T-shaped plate and an L-shaped slot which cooperate to prevent the nut and retainer from being removed while the nut is in place, and which permit removal of the retainer when the nut is not in place. The furniture can be painted before the nut, retainer and foot are attached, thereby preventing paint from contacting the threads of the nut. After painting, the retainer, nut, and foot are easily attached and adjusted. The retainer and beam are designed with vertical surfaces forming a pocket for receiving the nut and holding it in alignment with holes in the flange and retainer.

Abstract: This kiosk display unit comprises a pedestal consisting of three identical sheet metal panels which are secured together, to form a structure closed upon itself, by interengaging hook tabs and tab-receiving openings in flanges along edges of the panels. Because the panels are identical, to engage second and third panels to opposite edges of a first panel, the second panel must be moved relative to the first panel in one direction and the third panel must be moved relative to the first panel in the opposite direction. To engage the second and third panels with each other, a twisting movement is imparted to the assembly to allow the hook tabs and openings of the second and third tabs to become engaged with each other. Trapezoidal tabs and openings are used to facilitate entry of the tabs into the openings when the structure is twisted.The display unit also comprises a closed display section comprising three panels and three posts.
