A unique multiple work surface pullout unit that increases space utilization by providing multiple work surfaces for performance of multiple tasks marginally within the space allocated for one. Floors and structural walls, in addition to the framing elements of existing cabinets and counters may provide significant structural support/support frame function for a multiple work surface pullout unit. The multiple work surface pullout unit comprises at least two, generally rectangular in shape, work surfaces of appropriate dimension for the intended use of each work surface; a pair of primary slides and a pair of secondary slides, and means of connecting pairs of slides, identified herein as a pair of rails. Compact size is achieved in part by limiting load-bearing service to the primary slides. Said comprising components are configured and connected such that the work surfaces can move either together as a unit or independently and in either the same or opposite direction. Said pullout unit can be undocked (moved from storage area in the frame) to a useful exposure for a designated task and work surfaces in said pullout unit can be moved independently into and out of the work position for each work surface. Good design will accommodate simultaneous use of work surfaces.

A sliding assembly includes two pull-out guides which can be secured to opposite side walls and each of which includes a stationary guide rail, a middle rail movably mounted on the guide rail, and a running rail movably mounted on the middle rail. A first slidable element is retained on the two running rails of the two pull-out guides, and a second slidable element is retained on the two middle rails of the two pull-out guides. By moving one slidable element, the other slidable element can also be moved.

In a refrigerator including a sliding door configured to open and close a storage chamber, a storage basket provided on a rear portion of the sliding door, and a support frame configured to support the sliding door and the storage basket, sidewalls of the storage basket may be formed so as to protrude outwardly except a lower portion in which the support frame is disposed between an inner case and the sidewalls, thereby increasing a storage space of the storage basket. In addition, a front protrusion, an auxiliary protrusion, and a rear protrusion are formed in an upper portion of the storage basket, and therefore a relative position of an auxiliary basket to the storage basket may be limited, and the auxiliary basket may be drawn into and out in conjunction with drawn-in and-out movements of the storage basket.
