An arrangement has at least two door leaves which are connected to one another in an articulated manner, and can be moved between a parallel position, in which the at least two door leaves are oriented substantially parallel to one another, and a coplanar position, in which the at least two door leaves are oriented in a substantially coplanar manner. The arrangement includes a guide rail for fastening on a fixed furniture part, and a guide device to be connected to a folding/sliding door and mounted to be moved on the guide rail. The arrangement has a vertical carrier on which the folding/sliding door can be mounted in a pivotable manner. The guide rail and/or the guide device comprises a force store by which the folding/sliding door can be subjected to a force directed counter to the weight-induced force.

Lightweight, glidable shielded components (e.g. doors) may be used in conjunction with accredited enclosures to provide electromagnetic, acoustic and CBR protection.

A door system includes a panel to translate along a normal path between an open position and a closed position in front of a doorway in a wall. The door system further includes a first track to support the panel from an upper portion of the panel, and a second track to extend along the normal path proximate a lower portion of the panel. The door system also includes a spring to urge the panel toward the second track to maintain the panel in the normal path.

Example aspects of a sliding door assembly and a method for using a sliding door system are disclosed. The sliding door assembly can comprise a track assembly comprising a track assembly comprising a first track and a second track; a pivot assembly comprising a pivot carriage and a pivot mechanism engaging the pivot carriage, the pivot carriage configured to move along the first track; a locking carriage configured to move along the second track; and a sliding door comprising a door body and a locking pin, the locking pin removably engaging the locking carriage, and the door body configured to pivot at the pivot assembly relative to the track assembly.

A trailer truck is the combination of a truck and one or more trailers used to haul freight. A trailer attaches to the truck via a trailer coupling (hitch), with much of its weight borne by the truck. The result is that both the truck and the trailer will have a distinctly different design than a rigid truck and trailer. Exemplary vehicles are provided, such as heavy duty trucks having truck bodies with improved aerodynamic characteristics, including improved drag coefficients.

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.

A vehicle door opening and closing apparatus includes a rail mounted on a vehicle body, a roller unit mounted on a vehicle door, the vehicle door having a main latch releasably engaged with a main striker mounted on the vehicle body, the roller unit configured to allow the vehicle door to open and close in a sliding mode and a swing mode, and an outside handle operatively connected to the main latch, and including a handle base mounted on the vehicle door and a handle grip movably mounted on the handle base, wherein the handle grip is slidable in a longitudinal direction of a vehicle, and pivotal in a transverse direction of the vehicle, and wherein as the handle grip slides, the sliding mode is selected, and as the handle grip pivots, the swing mode is selected.

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.

A trailer truck is the combination of a truck and one or more trailers used to haul freight. A trailer attaches to the truck via a trailer coupling (hitch), with much of its weight borne by the truck. The result is that both the truck and the trailer will have a distinctly different design than a rigid truck and trailer. Exemplary vehicles are provided, such as heavy duty trucks having truck bodies with improved aerodynamic characteristics, including improved drag coefficients.

Systems, methods, and devices for a vehicle door or window are disclosed herein. A vehicle includes a vehicle body and a cabin located within the body of the vehicle, wherein the cabin includes an interior that is configured to accommodate at least one person. The vehicle includes at least one seat located in the interior of the cabin that is configured for seating a user. The vehicle includes at least one door that provides ingress and egress of the interior of the cabin of the vehicle, and the at least one door is located with respect to the body such that the door opens to provide ingress and egress of the cabin from a backside of the seat. Further, the door may be a cargo door, which allows access to the cabin for placement of a load, such as a cargo load on a pallet.
