A guide system for a door assembly including a door, which door can be attached to the guide system in a pivotal manner, has a closed position in which at least one device object can be covered on the front side and a parked position in which the door can be moved, preferably slid, in a direction transversely to the front of the at least one device object, preferably into a lateral receiving shaft, by the guide system. The guide system for the door is assembled or formed on a support structure separate from the device object to be covered, the support structure having at least one stand surface for standing on the floor of a room and/or at least one assembly device for assembling on the wall of a room.

A spindle drive, a spindle nut for the spindle drive, and a louvre window or louvre shutter having a spindle drive for moving louvre elements. The spindle nut is constructed in multiple parts including a screw nut part, having an internal thread to engage on an external thread of the threaded spindle, and a bearing part in which the screw nut part is mounted. The screw nut part includes a driver structure for transmitting a drive force applied by the threaded spindle to the spindle nut onto an element to be driven. Furthermore, the screw nut part is rotatably mounted in the bearing part in such a way that the screw nut part executes a relative movement in relation to the bearing part, and a directional component of the movement is transverse to a thread longitudinal axis of the internal thread.

A passage gate for allowing or preventing people to enter or to exit a passage area comprising a base portion (110) and a panel portion (120) is provided. The passage gate (100) is configured to be driven in a first operation mode and a second operation mode. When the passage gate (100) is driven in the first operation mode the panel portion (120) is slidable relative the base portion (110) between a first open position, allowing people to pass, and a closed position preventing people from passing through the passage gate (100). When the passage gate (100) is driven in the second operation mode the base portion (110) is rotatable between the closed position and a second open position for achieving a larger passage area.

An embodiment of the present disclosure provides a swing-in type of door structure of a vehicle that includes a door disposed in parallel at both sides of an entrance of a vehicle, and a door arm mounted on one side of the door to open or close the door by rotation, including: a center door bracket of which one end is fixed to one surface of an upper center of the door and that extends in a direction perpendicular to the door; a roller bracket of which one end is coupled to the other end of the center door bracket in a direction perpendicular to the center door bracket; and a roller mounted on the other end of the roller bracket and coupled to be rolled and rotated while in contact with a rail formed on a vehicle body of an upper side of the door.

A sliding door system includes an upper track; a lower track; a first sliding door comprising a first upper locking pin, a first lower locking assembly, and a first pivot assembly, the first pivot assembly engaging the upper track and the lower track, the first upper locking pin removably engaging the upper track, and the first lower locking assembly removably engaging the lower track; and a second sliding door comprising a second upper locking pin, a second lower locking assembly, and a second pivot assembly, the second pivot assembly engaging the upper track and the lower track, the second upper locking pin removably engaging the upper track, and the second lower locking assembly removably engaging the lower track.

A sliding door system includes an upper track; a lower track; a first sliding door comprising a first upper locking pin, a first lower locking assembly, and a first pivot assembly, the first pivot assembly engaging the upper track and the lower track, the first upper locking pin removably engaging the upper track, and the first lower locking assembly removably engaging the lower track; and a second sliding door comprising a second upper locking pin, a second lower locking assembly, and a second pivot assembly, the second pivot assembly engaging the upper track and the lower track, the second upper locking pin removably engaging the upper track, and the second lower locking assembly removably engaging the lower track.

A sliding door system and method is used in an enclosure that defines an inner area shielded against a High-Altitude Electromagnetic Pulse (“HEMP”). The HEMP shielded sliding door system includes an RF shielding door frame, an RF shielding door leaf mounted within an mechanical door leaf frame, a mechanical insertion and retraction assembly attached to both the mechanical door leaf frame and RF shielding door leaf and that operates to extend and retract the RF shielding door leaf into and out of the RF shielding door frame, a drive tube assembly operable to interact with and open and close mechanical door leaf frame (along with RF shielding door leaf) in a sliding motion, and a control assembly, including motor and an air regulator assembly. HEMP shielding air seals are activated when the RF shielding door leaf is inserted into the RF shielding door frame.

A container cabinet has a box-like structure and a door connected to the box-like structure by an articulated quadrilateral. The box-like structure has a first side shoulder and a second side shoulder, an upper panel, a lower panel, and a front part. The articulated quadrilateral, supporting and guiding the door from a door closing position to a door maximum opening position, has a crank having a first crank end and a second crank end, and a rocker arm. The crank is hinged with the first crank end to the door and with the second crank end to the upper or lower panel to rotate about a crank vertical rotation axis. The rocker arm is connected, on one side, to the door and, on an opposite side, to the first side shoulder and has a movable side panel having a movable side panel front end and a movable side panel rear end, respectively hinging the movable side panel to the door and to the first side shoulder.

A hybrid drive-thru door system that includes a door panel assembly movable between a plurality of operating modes. The door panel assembly includes a sliding door panel operable for movement between a closed position to at least partially cover a doorway opening and an opened position to at least partially expose the doorway opening. The sliding door panel has an upper sliding door panel member releasably attached to a lower sliding door panel member. The upper sliding door panel member is independently movable relative to the lower sliding door panel member in a window operating mode of the door panel assembly.

The invention discloses a synchronous sliding mechanism, a side hidden door system, and a cabinet body with the side hidden door system. The synchronous sliding mechanism comprises a guide rail and a first connecting rod mechanism, wherein the first connecting rod mechanism comprises two sliding ends provided on the guide rail; and when the guide rail reciprocates in a horizontal axial direction, the two sliding ends are close to or far away from each other. Through connection between connecting rods and the guide rail, the guide rail may reciprocate stably and synchronously. The synchronous sliding mechanism is widely suitable for furniture such as door bodies, cabinet bodies and the like, and has an excellent effect.
