The device comprises a main body, a fixing member affording fixing of a door leaf to the main body, a ball socket able to drive the main body under the effect of a motor, a roller able to move between (a) an active locking position in which the roller locks the ball socket with respect to the main body, in a closed position of the door leaf and (b) an inactive unlocking position in which a the roller allows displacement of the ball socket with respect to the main body. The device also includes a sleeve that allows a small movement of the fixing member with respect to the ball socket in a displacement direction from the closed position of the door leaf. The device further comprises a tooth that inhibits sleeve to immobilize the fixing member with respect to the ball socket, at least in translation in the displacement direction, when the roller is in the inactive position.

Assembly of door and doorframe, the door at a back vertical edge is hinged to a doorframe hinge side of the doorframe using door hinges at the upper and lower end of the door. The doorframe hinge side is designed with a cavity while a cover is rigidly attached to the door hinges up and down. The cover has a bore pivotally attached to cover hinges with vertical pivotal axis at the doorframe hinge side having a dimension adapted to be received within said cavity in the doorframe hinge side when the door is shut The cover has a curvature with a convex outer surface having the shape of a cylinder surface of a vertical imaginary cylinder, while the bore is so positioned that it forms a center axis in the imaginary cylinder and that this center axis is positioned externally in relation to the cavity.

A joining structure for two door members forming a door member for entrance opening and closing of an aircraft lavatory unit is configured so that a pair of brackets provided on the pair of door members are joined swingably by a bracket joining shaft; and one ends of a pair of covers are joined to the pair of brackets by bracket cover joining shafts, and the other ends of the pair of covers are joined swingably by a cover joining shaft, at a section farther away from the lavatory than the bracket joining shaft.

A vehicle includes a body and front and rear doors having front and rear powered latches, front and rear anti-pinch sensors, and front and rear electrically-powered door openers. The vehicle further includes a controller that is configured to receive an unlatch signal from unlatch sensors/switches and generate a signal to unlatch the front and rear powered latches and actuate the front and rear door openers after the front and rear powered latches are unlatched. The controller may also be configured to actuate the rear door opener to retain the rear door in an open position when the front pinch sensor detects a hand to thereby prevent pinching.

An embodiment of the present invention provides a multi-link hinge device in which any one of a plurality of links connecting a plurality of levers to each other may serve as a link and at the same time serve as a cover, thereby preventing a finger or the like from being caught in a space between the plurality of levers in advance when the door is opened or closed.

A flush-mount refrigerator is provided that includes a cabinet defining a compartment and including a pair of side walls that extends forwardly of the compartment. A pair of doors is coupled to the cabinet and positioned on either side of a centerline of the cabinet. The pair of doors are spaced apart by a predetermined spacing. A storage feature is positioned within the compartment of the cabinet and movable between an extended position and a recessed position when one or both of the pair of doors is in an open position. A hinge assembly is coupled to the cabinet and to one of the pair of doors. The hinge assembly includes a six-link mechanism that keeps the door within a predefined distance of at least one side wall when the door is moved from a closed position to the open position.

A refrigerator is provided herein. The refrigerator includes a cabinet defining a compartment. A door is configured to seal the compartment and is operable between open and closed positions. A hinge assembly is operably coupled to the cabinet and to the door. The hinge assembly includes a first link coupled to the cabinet. A second link is pivotable about the first link. A third link is pivotable about the second link and a fourth link. The fourth link is further coupled to the door. A fifth link is pivotable about the second link and the fourth link. A sixth link is pivotable about an intermediate portion of the fifth link and the first link. The sixth link is disposed through a void defined by the fifth link.

A retractable arm device, system, and method with a locking mechanism for preventing items placed in a device or receptacle from getting stuck, damaged, or torn. The retractable arm includes an inner tube, a pawl, and an outer tube surrounding the inner tube. The inner tube slides within the outer tube and the pawl preventing the retractable arm from moving into an extended position under particular conditions. The retractable arm may be placed in a receptacle for items to prevent the door from being reopened before the door is fully closed.

Electrically-operated inward-swing double doors and inward-swing door driving devices thereof. Each inward-swing door driving device includes a sector gear in coaxial transmission with a door shaft of the inward-swing door, a driving mechanism used for driving the sector gear to rotate, and an unlocking mechanism. The driving mechanism includes a motor gear and a motor driving the motor gear to rotate.

The unlocking mechanism includes a cylinder, a cylinder push rod extending out of the cylinder, and a lock located at the end portion of the cylinder push rod. The tail end of the lock is in transmission connection with a wheel axle of the motor gear. The lock is provided with a lock rotating shaft for rotating horizontally around the lock. The lock rotating shaft is provided with an elastic element for applying twisting resilience force to the lock.
