ABSTRACT:
A shelf (17) on a frame (18,19) sits within a tray-like structure provided by an intermediate frame (8), while the latter is supported by rails (6) and rollers (7). When pushed back into the storage position, the shelf (17) is stopped by a bar on the frame (8), with the rollers (21) on the shelf (17) at the rear ends of slots (12) in side plates (9) of the frame (8). The intermediate frame (8) is arrested by the outer framework (1). To gain clear access, the shelf (17) is pulled out horizontally, and it can shift with respect to the intermediate frame (8) a distance corresponding to the length of the slots (12). When it reaches the limit of this travel, the frame (8) is entrained and continued pulling draws it out, running on the rollers (7) and (13). The limit of its travel is defined by stops but when achieved the shelf (17) is fully clear of the framework and thus fully accessible. To restore the storage position, the shelf is simply pushed in again.
