A sliding apparatus for a sliding door comprises: a front top roller part including an upper outer bracket and an upper inner bracket; a front bottom roller part including a lower outer bracket and a lower inner bracket which are fitted and fixed to both lower ends of the front door while being connected to each other by a lower connecting bar, and are formed to slide in both lateral directions after moving forward; a rear roller part including rear outer brackets and rear inner brackets which are formed at both upper ends and both lower ends of a rear door formed on one side of the front door, so as to slide the rear door; a front rail part including guide rails which are formed on the upper and lower end surfaces of a rear door frame and the upper and lower surfaces of the rear inner bracket.

A guide assembly for use in a door of a refrigerator comprises: a sliding rail; a movable member located above the sliding rail; and a connection member connected and fixed to the door. The sliding rail comprises a slide and a track both extending in the left and right direction. The movable member can move along the slide in a reciprocating motion in the left and right direction. The movable member also has a sliding groove extending in the frontward and rearward direction. The connection member comprises a first roller disposed at the sliding groove and capable of moving along the sliding groove in the frontward and rearward direction. The guide assembly further comprises a guide structure disposed under the connection member. The guide structure is movably disposed in the track to guide the movement of the door.

A carriage arrangement has a driving bar arrangement and a carriage. The carriage has a roller part with a plurality of running rollers. The roller part is displaceable transversely to the longitudinal extent of the carriage with respect to a wing part which can be mounted immovably on a wing. A driving bar of the driving bar arrangement has a control projection which engages in a control slot which is formed obliquely to the longitudinal extent of the carriage. To guide the roller part on the wing part is provided a first roller bearing guide which extends transversely to the longitudinal extent of the carriage. The first roller bearing guide has rolling bodies which are supported both on the wing and roller part so forces acting in the direction of the longitudinal extent of the carriage are channelled away from the wing part into the roller part with low friction.

The present disclosure relates to a windows and doors assembly having a ventilation function and a horizontal contact function, and more particularly to a horizontal contact windows and doors assembly for crime prevention and security functions by preventing a window from being open even when the window is slightly open and it is possible to ventilate with the outside air. To achieve the objective of the present disclosure, the windows and doors assembly having a ventilation function and a horizontal contact function includes a window frame, and a windowsill in which the window frame is slidably installed, a handle rotatably installed on the window frame, an engagement unit provided on a lateral surface of the window frame, linked to movement of the handle, and moved in upward and downward directions, an engagement guide provided on the windowsill to face the engagement unit and configured to catch or not catch the engagement unit depending on a position of the engagement unit, and a horizontal moving device provided on at least one of a top surface or a bottom surface of the window frame, linked to the handle, and configured to make the window frame horizontally come into contact with the windowsill or to release horizontal contact depending on movement of the handle, and in this case, when a contact state of the window with respect to the windowsill by the horizontal contact device is released while a catching operation between the engagement unit and the engagement guide is performed, it is possible to ventilate through a gap between the window and the windowsill, the window is restrictly moved to form the gap, and the window is prevented from being freely open.

A displacement arrangement for displacing a sliding leaf of a window or a door relative to a fixed surround of the window or the door in a direction which is transverse relative to a main plane of the window or the door includes an actuation mechanism arranged on the leaf that is movable with at least one portion in a circumferential direction of a rebate, a first control element arranged on the portion of the actuation mechanism and a second control element arranged on a guiding member, where the guiding member is guided on a fixed surround and arranged on the leaf to be movable transversely relative to the circumferential direction of the rebate.

A pivot sliding door assembly for a vehicle with a door wing for opening and closing a door opening. The pivot sliding door assembly is secured against disengagement in a Z-direction. The assembly includes a rotary column assembly for displacing the door wing between a closing position and a displacing or open position. The door wing closes the door opening when in the closing position and the door wing can be displaced in the displacing position for opening the door opening along a displacement direction.

A door including a barrier-free sill is disclosed. A reliable seal or transverse support of the leaf in the event of wind pressure or an attempted break-in is achieved by at least one projection of a carriage, which extends into a guide groove. The projection extends further down than a running roller of the carriage. This enables the design of a particularly stable and yet barrier-free door.

A door including a barrier-free sill is disclosed. The sill preferably has recesses on its upper side, the width of the recesses being less than 50 mm and/or the depth of the recesses being less than 3 mm. A leaf can penetrate the upper side in a leaf recess. The leaf may fall below the vertically uppermost dimension of a running rail. Using at least one projection of a carriage that extends into a guide groove, it is possible to reliably seal or transversely support the leaf in the event of wind pressure or a break-in attempt. The projection preferably extends further down than a running roller of the carriage. This enables the design of a particularly stable and yet barrier-free door.

Provided are a railroad vehicle that makes it possible to maintain the air tightness of a door and a plug door for a railroad vehicle. A second rail is provided parallel to a first rail in the longitudinal direction of a vehicle body above the leading edge side (door side) of a plug rail. The second rail supports the leading edge side of the plug rail. As a result, both edges of the plug rail are supported by the first rail and the second rail. Dangling of the leading edge side of the plug rail is thus prevented even when the plug distance (the distance that the door moves in the vehicle body width direction) is long. In this way, it is possible to block the doorway without leaving a gap using the door and to maintain the air tightness of the door.

An electrically driven sliding window for vehicle and a vehicle include a window aperture, guide rails, bases, slide blocks, a movable glass unit and an electric drive mechanism, the guide rails are provided on two opposite sides of the window aperture respectively, the slide block includes a base mating portion and a guide rail mating portion, the slide block is slidably mounted on a base via the base mating portion and is mounted on a guide rail via the guide rail mating portion, the movable glass unit is fixed on the bases, and the slide blocks are slidable along the guide rails and are slidable relative to the bases by means of the electric drive mechanism, to drive the bases to perform a sliding movement parallel to a direction of the guide rails and a movement for alignment perpendicular to the direction of the guide rails.
