A refrigerator includes a cabinet including an inner case, and a drawer assembly installed in the inner case. The drawer assembly includes a basket which forms a receiving space and can be pulled in and out of the inner case, a supporter assembly connected to the basket to guide an insertion or withdrawal of the basket, and a cover connected to the supporter assembly to cover or uncover the receiving space. The cover may be movable in a direction opposite to a movement of the basket when the basket is inserted or withdrawn. The basket includes a protrusion configured to engage with or disengage from a notch of a connection member to facilitate or prevent transmission of a movement force of the basket to the cover.

A sliding-pivoting mechanism of a shelf of a piece of furniture or of a household appliance for extracting and raising the shelf out of a body of the piece of furniture or of the household appliance is provided. The mechanism includes at least two pivot arms of a pivoting mechanism, which are rotatably fixed by a first end to at least one of the side walls of the body, parallel to the plane of the side walls, and which are arranged parallel to and at a distance from each other. At respective second ends of the pivot arms, a guide rail of a sliding mechanism is pivotably fixed parallel to the plane of the side walls such that the guide rail is pivotable from a lower position within the body into a raised, upper position at least partially outside the body, at least one running rail that is linearly displaceable in the guide rail and to which the shelf is fixed. The sliding-pivoting mechanism includes a lever unit supporting raising and lowering of the pivoting mechanism and is pivotably fixed to the running rail parallel to the plane of the side walls. A coupling element of a first coupling unit is arranged on the lever unit such that the coupling element is couplable to at least one of the pivot arms with a corresponding element of the first coupling unit, which corresponds to the coupling element, by displacing the running rail into a predetermined pivoting position.

A rack includes: a casing; M (an integer not less than three) pairs of supports that are provided inside the casing so as to extend in a depth direction and arrayed at regular intervals in a predetermined direction (a height direction or a left-right direction); and a lock mechanism. The rack can house all returnable containers of one or more prespecified sizes along the respective pairs of supports. The lock mechanism includes N (an integer not less than two and meeting N<M≤2.sup.N−1) shafts that are movable in the predetermined direction. Branches are provided on the shafts such that a combination of engagement and disengagement between the branches and holes provided in protrusions of the returnable container is different in each of the returnable containers housed on the respective M pairs of supports.
