A slide door support device supports a slide door that opens and closes a door opening formed on a side surface of a vehicle body. The slide door support device includes first and second lower rails and a lower guide unit. The lower guide unit includes a first lower guide roller moving along the first lower rail, a second lower guide roller moving along the second lower rail, a lower fixed portion fixed to the slide door, a lower rotational arm rotatable relative to the lower fixed portion and supporting the first and second lower guide rollers, and a pressing member pressing the lower fixed portion. An arm angle made by the lower fixed portion and the lower rotational arm gradually decreases as an opened degree of the slide door decreases. The pressing member presses the lower fixed portion in a direction of increasing the arm angle.

A latch member for full opening includes a latch member for full opening that operates a latch claw into an engagement position or a non-engagement position with a striker. The latch member for full opening is configured of a first member on a sliding door side of a turning shaft, and is configured of a second member operated by the first member on a vehicle body side of the turning shaft.

A fitting assembly for a window or door includes a leaf tiltable and detachable from, and slidable parallel to, the fixed window or door frame, and a control element with a fastener mountable permanently on the frame and an insertion part pivotable and slidable relative to the fastener. In an insertion position, in which a control pin is pushable into the insertion part, an insertion part end section lies preferably partially against the fastener for conducting away control pin-insertion part impact into the fastener via the end section. The insertion part may pivot out of interlocking engagement with the fastener by a control arm on which the control pin may be located or formed, such that subsequently the insertion part can slide via the control pin. The control element can have a freewheel mechanism for pivoting the insertion part only during fitting assembly opening and not during closing.

A roller carriage arrangement for a door or a window of a building, wherein the window or the door has a fixed frame and a leaf which can be released from the fixed frame and which can be displaced relative to the fixed frame together with the roller carriage arrangement.

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.

The present invention is directed to a stepless sliding doors system, comprising: two sliding doors (10), at least one of them comprising: two vertical poles (30); means (50) for rotating each of the vertical poles (30); to each side of the vertical poles (30) is firmly connected a hand-connector (36); each of the hand-connectors (36) is pivotally connected to a rail-cart (18) having two rollers (42); each of the rail-carts (18) comprises a horizontal hinge (58) disposed between the rollers (42), and a vertical springy hinge (70), for applying pulling or pushing force of the rollers on a rail thereof, thereby allowing placing the sliding doors of the system in the same plane when in the closed state of the doors, and shifting the doors one along the other in the open state thereof, and additionally preventing the wheels to deviate from a rail in the case of slight deformations.

A sliding door structure in which a position where a door side end-section of a vehicle body rail support member is coupled to a door main body being further to a door closing direction side than a center-of-gravity position of a door, and a position of a door side end-section of a door rail support member in a fully open state being further to a door closing direction side than the center-of-gravity position of the door and further to a door opening direction side than a position where the door side end-section of the vehicle body rail support member is coupled to the door main body, and that further includes: an inclination suppressing wall provided at a vehicle body and configured so as to be abutted, from a vehicle lower side, by a reaction force generating section at least in the fully open state.

A sliding door system for a building wall includes first and second wall parts having opposite first and second door openings respectively and separated by an intermediate space, first and second door leaves closing the first and second door openings respectively, a door leaf carrier slidable along the intermediate space by a linear guide device and on which the door leaves are pivotably mounted by a pivot mechanism, and a coupling device converting the carrier sliding movement into a rotational movement actuating the pivot mechanism so that the door leaves pivot relative to the door leaf carrier, the coupling device including a slotted component with a slot representing a desired relationship between the sliding movement and the rotational movement and a control lever coupling the slot to the pivot mechanism, and wherein the slotted component is mounted on at least one of the first and second wall parts.

A slide door support mechanism includes a lower rail provided on a vehicle body, a rear slide door configured to open and close a rear door opening portion of the vehicle body by slide movement, a door rail provided on the rear slide door, a first arm that bridges between the lower rail and the door rail, a vehicle body-side roller unit and a vehicle body-side roller provided on the first arm and slidably provided on the lower rail, a door-side roller provided on a first arm and slidably provided on the door rail, and a second arm pivotably supported by the rear slide door and the first arm.
