A refrigerator includes a cabinet defining a storage chamber, a drawer door, a motor assembly provided at the storage chamber and configured to provide a driving force that moves the drawer door relative to the storage chamber, and a rack gear assembly provided at the drawer door and having an extendable rack gear. The rack gear includes a fixed rack fixed to the drawer door and a moving rack slidably coupled to the fixed rack. The drawer door includes a drawer part that defines an upwardly open storage space, and a door part that is configured to, based on the drawer door being inserted into the storage chamber, close the storage chamber.

A sliding tray system for a storage unit to allow a user to easily access and utilize the rear of an elevated storage unit. The sliding tray system has a tray, roller supports, rollers, two tracks, and a pull strap. The tray has a well having a bottom wall, side walls and flanges extending outwardly from the side walls at a top of the well. The rollers are secured to the roller support and ride within the tracks. Additionally, retaining walls are secured to the flanges to provide a rear wall for the sliding tray system. Preferably, the retaining walls do not extend from the second end of the tray all the way to the first end of the tray.

A roller carriage for displaceable linear guidance in a longitudinal direction on a rail element is disclosed. The roller carriage includes a carrier, a first roller or pair, a second roller or pair, and roller or pair. Every one of the first roller or pair, the second roller or pair, and the third roller or pair is mounted on the carrier such that each can rotate about a rotating axle. The rotating axles are substantially parallel to one another and the first roller or pair, the second roller or pair, and the third roller or pair are disposed on the roller carriage such that the first roller or pair can be brought into engagement with a first track of the rail element and the second roller or pair and the third roller or pair can be brought into engagement with a second track of the rail element. One of the first roller or pair, the second roller or pair, and the third roller or pair is mounted such that it can move in a transverse direction perpendicular to the longitudinal direction relative to the carrier, and wherein the movably mounted roller is resiliently pretensioned in transverse direction by a first spring element.

Runner assembly 10 for carrying a receptacle 12 towards and away from a structure 14. The runner assembly 10 includes: at least one pair of first bearings 16, each first bearing 16 being mountable to the structure 14 so that the first bearings 16 of the, or each, pair are spaced apart; an elongate runner 18 defining a longitudinal length and having an opposed pair of first tracks 22 spaced from each other, each first track 22 configured to cooperate with the first bearings 16 to allow the runner 18 to be carried by the first bearings 16; at least one second bearing 24 mounted to the runner 18; and an elongate track member 26 mountable to the receptacle 12, the track member 26 having a second track 28 defining at least one pair of opposed bearing surfaces 30, 31 spaced from each other and configured to cooperate with the at least one second bearing 24 to allow the track member 26 to be carried by the at least one second bearing 24.

A slide rail assembly includes a first rail, a second rail, a third rail, and a position-limiting member. The third rail is movably mounted between the first and the second rails. The second and the third rails can be displaced with respect to the first rail from a predetermined position in a first direction. When the second and the third rails are at the predetermined position with respect to the first rail, a first portion of the position-limiting member is adjacent to an end portion of the three rails, and a second portion of the position-limiting member prevents the three rails from separating from one another in a second direction substantially perpendicular to the first direction.

A pullout guide comprises a stationary guide rail which can be fixed to a body, a middle rail which is movably held on the guide rail via first rolling elements arranged in a first rolling element cage, a running rail which is movably held on the middle rail via second rolling elements arranged in a second rolling element cage, and an opening on the middle rail for a support element, which, in a retracted position of the pullout guide, supports the running rail on the guide rail, the support element being mounted on the middle rail such that it can be lowered. In this case, the opening for the support element can be passed over by at least one second rolling element. This allows the support of the running rail to be optimized.
