A retractable sliding door (10) with automatic alignment to the wall (12) during the closing phase, suitable to alternately open and close a through space (14) made along said wall, comprising a lower guide (18) fixed to the floor and an upper guide (20) forming a support beam. In the upper guide (20) paired prominences (50, 52) and (60) are made constituting the sliding tracks of two or more pairs of wheels (54) and single wheels (58) borne by a shaft (56) and combined with a frame (62) to form a carriage. The lower guide (18) interacts with a roller (24) suitable to fit into a shaped channel with a mixed-line extension (26) made along the lower head of the door (10); the upper guide (20) is provided with a shaped channel (78) having the same and parallel mixed-line configuration as said shaped channel (26). The upper head of the door (10) being provided with means for its suspension to the frame (62) constituting the carriage.

A wine cabinet, which comprises a main cabinet body, and further comprises a transparent display cabinet body arranged at a top end of the main cabinet body, a control mechanism, a driving mechanism connected with the control mechanism, and an automatic lifting and sliding mechanism connected with the driving mechanism. A display chamber of the display cabinet body is separated from a storage chamber of the main cabinet body by a laminated plate, the control mechanism, the driving mechanism and the automatic lifting and sliding mechanism are arranged in the storage chamber, and an opening is arranged at a side of the top end of the display cabinet body. The opening is covered with a transparent movable cover plate and the automatic lifting and sliding mechanism is connected with the movable cover plate.

An intelligent window allowing ventilation has an outer frame, a sliding frame, an upper locking rod, a lower locking rod, a driving module, a power supply module, and a switch assembly. The sliding frame is slidably mounted in the outer frame. The switch assembly controls the driving module to selectively drive the upper locking rod and the lower locking rod to two locking positions respectively, two ventilation positions respectively or two unlocking positions respectively. Since no handle is needed, an appearance of the intelligent window is neat and scenery outside the intelligent window would not be sheltered. In addition, by actuating the switch module to electrically drive the upper locking rod and the lower locking rod, a user is able to switch the intelligent window to a locked state, a ventilation state or a unlocked state. It is labor-saving and simple in operation.

A door panels-frame assembly includes a first revolving door panel, a second door panel that slides relative to the first door panel, and a supporting frame fixed to the door panels in order to movably support the door panels. The supporting frame has first sliding mechanism fixed to the second door panel to make the second door panel slide relative to the first door panel, the sliding mechanism including a fixed slide where a slider slides. The slide has an inclined end relative to the sliding direction of the second door panel when moved by the first sliding mechanism, in such a way to push the second door panel outwards when it is opened.

A door system is provided for use with a door and a door frame defining an entry opening to provide selective closing and opening of the entry opening. The door system can be used to convert a conventional hinged door into one providing less obtrusion into space in front of and behind the respective entry opening. The door system includes an overhead movement mechanism providing at least two transverse directions of movement, and one or more hinge replacement mechanisms providing latching of the door at a lateral side opposite the door handle. The movement mechanism is configured to move the door between a closed orientation in the door frame and an open orientation horizontally spaced from the entry opening. The open orientation is disposed along an adjacent wall having the door frame. A standard door handle, strike and strike plate are used to move and to lock the door.

A door roller includes a carriage member comprising a plurality of bores, and a plurality of roller assemblies connected to the carriage member, each roller assembly of the plurality of roller assemblies including a pivot bearing rotatably disposed within a bore of the plurality of bores and a pair of rollers coupled to the pivot bearing. Each wheel assembly is configured to pivot relative to the carriage member.

A spindle type structure includes a lower rail mounted in a longitudinal direction at a lower side of a vehicle body, a lower rail roller unit rollably connected to the lower rail, a lower rail swing arm rotatably connected to the lower rail roller unit and a door, a lower guide rail mounted on the door and configured to form a lower guide route in the longitudinal direction, and a spindle assembly positioned at one side of the lower rail, the spindle assembly including a spindle connected in the longitudinal direction to a fixing unit fixed to the vehicle body, having one end rollably connected to the lower guide rail, having a threaded portion formed on an outer circumferential surface thereof, and being configured to be movable in a threaded manner between the vehicle body and the door.

The disclosure relates to a sliding fenestration system assembly, such as a door or window system. The sliding fenestration system includes a sill having a first track channel and a second track channel formed thereon. A sill track including a first track segment, a second track segment, and a third track segment is coupled to the sill such that the first track segment is positioned within the first track channel, the third track segment is positioned within the second track channel, and the second track segment extends between the first and second track channels. The system further includes a sliding panel having one or more bottom guide assemblies, the assemblies engaging the sill track and operable to accommodate movement of the sliding panel along the sill track to reduce friction at a sealing interface between the sliding panel and the fenestration frame assembly.

A sliding/swing complex door for a vehicle includes a sliding door configured to be opened upon a first operation of an outside handle positioned on an outside of the sliding door, a swing door configured to be integrated and opened with the sliding door upon a second operation of the outside handle, and a fixing unit configured to be opened in such a way to be integrated and rotated with the swing door in a state in which the sliding door is fully opened.

A link mechanism for a vehicle door is provided. The link mechanism includes a body having a first end portion facing a vehicle body and a second end portion facing a vehicle door and a first mounting member that is mounted on the vehicle body, and rotatably connected to the first end portion of the body through a first shaft. A second mounting member is mounted on the vehicle door, and is rotatably connected to the second end portion of the body through a second shaft. A rotation restricting unit selectively restricts a rotation of the second mounting member.
