A refrigerator includes a cabinet including an inner case; and a drawer assembly installed in the inner case, in which the drawer assembly includes: a basket which forms a receiving space and can be pulled in and out of the storage chamber; a supporter assembly connected to the basket, the supporter assembly to guide the pulling-in and out of the basket; and a cover connected to the supporter assembly, the cover covering the receiving space, the cover being movable in a direction opposite to the basket when the basket is pulled in and out. The basket includes a first roller installed close to a rear end of the side wall thereof.

A refrigerator includes a cabinet defining a storage chamber, a drawer door, a rail assembly that slidably couples the drawer door to the cabinet, a driving device disposed at the door part, and an elevation device disposed at the drawer part to vertically elevate at least a portion of the drawer part. The driving device includes a motor assembly, a pair of screw units, and a pair of levers, each of the pair of levers being coupled to and configured to be rotated by a corresponding one of the pair of screw units to elevate the elevation device. The drawer door includes a door part configured to open and close the storage chamber and a drawer part that is configured to be inserted into and withdrawn out of the storage chamber and defines a storage space.

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 three-section linkage drawer slides apparatus, includes an upper rail, a middle rail, a fixed rail, an upper linkage rack, and a lower linkage rack, wherein the middle rail is slidably connected to the fixed rail through the lower linkage rack, the upper rail is slidably connected to the middle rail through the upper linkage rack, the upper linkage rack and the lower linkage rack are of separate structures, the upper linkage rack is mounted between the middle rail and the upper rail after being assembled, and the lower linkage rack is mounted between the fixed rail and the middle rail after being assembled. The upper linkage rack and the lower linkage rack are configured as separate structures, the manufacturing process can thus be simplified, so the manufacturing cost is reduced.
