ABSTRACT The pivoting tray for corner cupboards is a one-piece plastic tray in the form of a complete circle or segment of a circle. The pivoting tray has a supporting plate (1) stiffened, on the underside of the tray, by radial ribs (5) and having a central pivot bearing (2), and a raised rim (3) which runs around the casing side. During manufacture, the ribs (5) are broadened over part of their height at the junction with the underside (1a) of the supporting plate to form hollow profiles (6). The hollow profiles (6) of the ribs (5) run radially from the pivoting bearing (2) to the edge (3) of the supporting plate. Each rib (5) is formed from an upended ridge (7) and the hollow profile (6) between the ridge (7) and the underside (10a) of the supporting plate; the hollow profile has a larger cross-section than the ridge (7) and roundings (8) where it merges into the ridge (7) and the supporting plate (1). Radial non-slip ribs (10) are formed on the upper side (1b) of the supporting plate (1). The pivot bearing for pivoting trays of this type has a vertical tube (13) which can be mounted in a corner cupboard and on which the pivoting tray together with a cage bearing (15) is rotatably mounted and is pivotally mounted together with this cage bearing (15) on a cage support (16) which is secured against rotation about the vertical tube (13). The cage bearing (15) and the cage support (16) have facing sliding flanges (17, 18). The cage bearing (15) is a one-piece plastic adapter and has at least one shaped driver ridge (22) inserted in a groove (21) in the pivotal bearing (2) of the pivoting tray.
