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 space-saving lengthwise and widthwise movable panel system capable of being fully opened belongs to the field of smart building technology and includes a lengthwise panel moving compartment, a panel storage space and a panel control module. The movable panel system can be used as a door and/or window system. All of the panels of the system can be entirely stored in the panel storage space and when storing all of the panels entirely in the panel storage space, the panel system is fully open to allow full lengthwise access to a space. The panel storage space may be located in a wall or outside the room to hide the stacked panels. By controlling the operation of the moving system, the panels are effectively connected to one another in an aligned manner and can move automatically, so the space-saving movable panel system is convenient to use, and space-saving.

The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body. A guide block is provided on the door, a rotation shaft is provided on the hinge body, and rotation shaft grooves are provided on the guide block. With the structure of the hinge body, the gravity of the door and the friction force may be shared onto the first and second plate bodies of the hinge body, thereby reducing abrasion and prolonging the service life of the door of the refrigerator.

A step device for a vehicle includes a movable step and a coupling member. The movable step includes a guide rail. The coupling member is configured to cause the movable step to move from a deployed position to a retracted position as a engaging part comes into sliding contact with a side wall of the guide rail that is located on an inner side in a vehicle width direction and, while pressing the side wall, moves inside the guide rail in a direction of closing a sliding door. The guide rail is configured such that a terminal end region on a closing side including a terminal end position at which the engaging part is located when the sliding door is fully closed constitutes a closing-side free running zone in which the engaging part does not press either of the side walls.

A refuse vehicle includes a body including a cab, a door assembly, and a linkage assembly. The door assembly is coupled to the cab and includes a first door panel and a second door panel. The first door panel is rotatably coupled to the second door panel and has an unfolded position and a folded position. The linkage assembly is configured to reposition the door assembly between a closed position and an open position relative to the cab. In a first state the door assembly is in the closed position the second door panel is in the unfolded position, and in a second state the door assembly is in the open position and the second door panel is in the folded position. The linkage assembly may include a first linkage coupled between the cab and the door assembly and a second linkage coupled between the cab and the door assembly.

A panel is supported by a track for movement along the track between a closed position and an open position, and is further supported by a pivot assembly that is configured to pivot the track and the panel with respect to a body portion.
