A pre-assembled fitting group for a window or door has a drive rod portion, which is movable in the rebate circumferential direction, a first control element, and a second control element which is arranged on a cross slide. The first and the second control elements cooperate and are coordinated with one another in such a way that a displacement of the first control element by the drive rod portion causes a displacement of the cross slide. A guide part that can be fixedly mounted on the sash, wherein the cross slide is at least partially movable relative to the guide part.

A door-and-window system having a handle component (121), a transmission component (123) and a force receiving portion (12231). When the handle component (121) is operated, the force receiving portion (12231) moves along a first guide groove (12211) via the transmission component (123), and at the same time a driving portion (12232) moves along a second guide groove (12221). Due to a relationship between a guide member (1224) and a third guide groove (12212), a first base seat (1221) translates relative to a second base seat (1222) along a direction of the third guide groove (12212), such that a movable door-and-window (11) can abut tightly against or move away from a sealing member (24) on a door-and-window mounting profile (2).

A displacement arrangement for moving a window sash or a door leaf has a control part which is displaced by an actuating device relative to a guide part which can be mounted fixedly on the sash/leaf. A first control projection is provided between the control part and actuating device and engages in a first control slot of the control part and engages in a first guide slot of the guide part. The first control projection has a first rolling bearing for bearing on the first guide slot. The first control projection can have a second rolling bearing for supporting on the first control slot. A supporting rolling bearing can be provided between the guide part and the control part. The displacement arrangement allows the generation of a high contact pressure of the sash/leaf on the fixed frame under moderate operating forces and thus good sealing of the window or the door.

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 sliding door assembly includes a door panel, a frame that supports the door panel and includes a bottom member with a lower profile and a top member with an upper profile, wherein the lower profile and the upper profile are parallel to one another. A lower sliding assembly is operatively coupled to a bottom of the door panel and engages the lower profile, and an upper sliding assembly is operatively coupled to a top of the door panel and engages the upper profile. A gasket interposes the door panel and a portion of the frame when the door panel is in a sealed position. The door panel is movable between the sealed position, where the gasket creates a sealed interface between the door panel and the frame, and a sliding position, where the door panel is moved laterally relative to the frame while remaining substantially perpendicular to a floor.

A closure device for closing an access opening in a motor-vehicle body. An inner chamber is accessible via the access opening and the access opening can be closed by a cap element. The cap element is connected to a guide device, which is arranged in the inner chamber and via which the cap element can be adjusted between a closed position and an open position. The guide device is configured such that the cap element executes a pushing movement and a lifting movement as it moves between the closed position and the open position. The cap element, in the open position, is arranged in the inner chamber.

A displacement arrangement for moving a window sash or a door leaf has a control part which is displaced by an actuating device relative to a guide part which can be mounted fixedly on the sash/leaf. A first control projection is provided between the control part and actuating device and engages in a first control slot of the control part and engages in a first guide slot of the guide part. The first control projection has a first rolling bearing for bearing on the first guide slot. The first control projection can have a second rolling bearing for supporting on the first control slot. A supporting rolling bearing can be provided between the guide part and the control part. The displacement arrangement allows the generation of a high contact pressure of the sash/leaf on the fixed frame under moderate operating forces and thus good sealing of the window or the door.

Disclosed is a door-and-window system, in which a handle component (121) is assembled via a transmission component (123) with a force receiving portion (12231) of a movable door-and-window assembly component (122). When the handle component (121) is operated, the force receiving portion (12231) moves along a first guide groove (12211) thanks to the force transmission effect of the transmission component (123), and at the same time a driving portion (12232) moves along a second guide groove (12221). Due to an assembly relationship between a guide member (1224) and a third guide groove (12212), a first base seat (1221) translates relative to a second base seat (1222) along a direction of the third guide groove (12212), such that a movable door-and-window (11) can abut tightly against or move away from a sealing member (24) on a door-and-window mounting profile (2). Thus, while operating a handle (1211) for locking or unlocking, sealing or unsealing is achieved between a movable door-and-window subsystem (1) and the door-and-window mounting profile (2), noise is effectively reduced, and anti-shock performance is improved as well.

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 sliding door assembly includes a door panel, a frame that supports the door panel and includes a bottom member with a lower profile and a top member with an upper profile, wherein the lower profile and the upper profile are parallel to one another. A lower sliding assembly is operatively coupled to a bottom of the door panel and engages the lower profile, and an upper sliding assembly is operatively coupled to a top of the door panel and engages the upper profile. A gasket interposes the door panel and a portion of the frame when the door panel is in a sealed position. The door panel is movable between the sealed position, where the gasket creates a sealed interface between the door panel and the frame, and a sliding position, where the door panel is moved laterally relative to the frame while remaining substantially perpendicular to a floor.
