A refrigerator including: a main body forming a storage compartment and a door provided to open and close the storage compartment, wherein the door includes a door frame, a cover arranged in front of the door frame and including a cover fixer, and a door panel arranged in front of the cover, the door panel including a first fixer and a second fixer on a rear surface of the door panel. When the door panel is coupled to a front side of the cover, the first fixer is coupled to the door frame and the second fixer is coupled to the cover.

An intelligent window allowing ventilation has an outer frame, a sliding frame, an upper locking rod, a lower locking rod, a driving module, a power supply module, and a switch assembly. The sliding frame is slidably mounted in the outer frame. The switch assembly controls the driving module to selectively drive the upper locking rod and the lower locking rod to two locking positions respectively, two ventilation positions respectively or two unlocking positions respectively. Since no handle is needed, an appearance of the intelligent window is neat and scenery outside the intelligent window would not be sheltered. In addition, by actuating the switch module to electrically drive the upper locking rod and the lower locking rod, a user is able to switch the intelligent window to a locked state, a ventilation state or a unlocked state. It is labor-saving and simple in operation.

A sliding door system for inline closure of an opening in the wall of a structure, which may be a building or an item of furniture, for example, that includes a door panel, a guiderail assembly, and a guiderail coupled to the wall mount via a plurality of doubled-hinge assemblies that together serve to allow the guiderail to pivot towards and away from the wall, and includes a stop on the guiderail that serves as a catch, or cam, that causes a closing force on the door panel to be transferred to the double-hinge assemblies and to cause the door panel to be pulled into inline closure in the opening.

Systems and methods for providing a door seal system for top-hanging sliding doors. In some implementations, two angled mating surfaces are used, one angled surface on a fixed frame and one reversed angled surface on the slideable door panel. The slideable door panel slides directly parallel to the fixed door frame. A mating seal surface is created that is only in frictional contact for a small portion of the linear slide distance of the door panel. In some implementations, rather than placing two opposing angled seal surfaces, the sealing system has one angled surface on the fixed door frame. In such implementations, the sliding door panel is adjusted to be in a reverse angled orientation relative to the angled surface of the fixed door frame. Seal designs for the rear vertical edge of the slideable door panel are also provided herein.

A refrigerator including: a main body forming a storage compartment and a door provided to open and close the storage compartment, wherein the door includes a door frame, a cover arranged in front of the door frame and including a cover fixer, and a door panel arranged in front of the cover, the door panel including a first fixer and a second fixer on a rear surface of the door panel. When the door panel is coupled to a front side of the cover, the first fixer is coupled to the door frame and the second fixer is coupled to the cover.

A sliding door apparatus capable of effectively restraining sliding movement of a door body is provided. A sliding door apparatus 1 includes: a rail 20 having an inner surface 24 formed to have a concave shape, the inner surface 24 having a first support surface 24A and a second support surface 24B which are not parallel to each other; a hanger 30A, 30B having a first driving member (32, 37) in rolling contact with the first support surface 24A, and a second driving member (33, 38) in rolling contact with the second support surface 24B; and a door body 40 configured to be moved in a longitudinal direction of the rail 20 through the hanger 30A, 30B. When seen along the longitudinal direction of the rail, the first support surface 24A and the second support surface 24B are formed to come close to each other as they extend toward a bottom of the inner surface 24.

Disclosed is a sliding door or window. The sliding door or window includes a door/window frame, a swing fastening mechanism is disposed at a lower end of a side of the door/window frame, and a locking structure is mounted on an upper end of the side of the door/window frame. The swing fastening mechanism and the locking structure are each provided with a snakelike groove inside which a shaft operative to slide along a groove orientation is arranged. A handle disposed on the door/window frame is operative to drive the shaft to slide in the snakelike groove, thereby forcing the swing fastening mechanism or/and the locking structure to swing.

A sliding door system for inline closure of an opening in the wall of a structure, which may be a building or an item of furniture, for example. The sliding door system includes a door panel, a guiderail assembly having a wall mount fixedly attached to the wall above the opening and a guiderail coupled to the wall mount via a plurality of doubled-hinge assemblies that together serve to allow the guiderail to pivot towards and away from the wall. The top portion of the door panel has one ore more roller assemblies that are slidably coupled to the guiderail via rollers. A stop on the guiderail serves as a catch, or cam, that causes a closing force on the door panel to be transferred to the double-hinge assemblies and to cause the door panel to be pulled into inline closure in the opening.

An apparatus for window is used for moving a movable window plate among an insertion position for being inserted into an aperture portion of a fixed window plate, an extraction position for being extracted from the aperture portion toward an indoor side, and an opening position for being moved from the extraction position in a sliding direction that is different from an inserting and extracting direction to open the aperture portion. The apparatus includes a rotating shaft rotatably supported at a predetermined position for the movable window plate; a movement conversion mechanism configured to convert a rotation of the rotating shaft into a translation of the movable window plate between the insertion position and the extraction position; and a drive shaft, fixed to the rotating shaft, configured to rotate the rotating shaft around a central axis of the rotating shaft by revolving around the central axis of the rotating shaft.
