The present application discloses a sliding door comprising a door body, a supporting structure, a guiding structure, a lower sliding rail module and an upper sliding rail module, the supporting structure and the guiding structure are respectively fixed with the door body; the lower sliding rail module comprises first and second lower sliding rails; the upper sliding rail module comprises first and second upper sliding rails; when the door body, the first upper sliding rail and the first lower sliding rail are on the same plane, the door body is in a closed state, and when the door body, the second upper sliding rail and the second lower sliding rail are on the same plane, the door body is in an open state. Thus, the present application enables the door body to not occupy the width of the doorway in the open state.

A slide door apparatus for a vehicle includes: a guide rail extending in a front and rear direction along a peripheral edge of a door opening part formed on a lateral side of a vehicle body; and a guide roller unit supporting the slide door on the lateral side, in which the guide rail includes first and second guide roller engagement units extending in the front and rear direction in parallel with each other in a width direction, and the first guide roller engagement unit includes a first curved portion, and the second guide roller engagement unit is disposed inside in the width direction compared to the first guide roller engagement unit such that a distance of the second guide roller engagement unit from the first guide roller engagement unit in the width direction is decreased at an end portion side in the closing direction of the slide door.

A wall panel storage system includes a looped element and a motor for driving the looped element. A plurality of spacers are attached to the looped element with at least one spacer of the plurality of spacers being configured to fit vertically or be inserted between a pair of panels to move a panel of the pair of panels into or out of a storage area along a storage track when the motor drives the looped element.

An architectural covering may include an adjustment member configured and positioned to adjust friction affecting movement of the covering. The adjustment member may be manipulated to increase friction in the architectural covering so a covering member (e.g., a panel) of the architectural covering does not move as freely as it would without the increased friction, yet the covering member nonetheless remains simple to operate. The additional friction may be effective to inhibit the covering member from moving across an associated architectural feature on its own without a user's input.

A plurality of spacers is attached to the looped element with at least one spacer of the plurality of spacers being configured to fit between a pair of panels to move a panel of the pair of panels into or out of a storage area when the motor drives the looped element. According to one aspect, a wall panel storage system includes a first wall panel storage device adjacent a first track and a second wall panel storage device adjacent a second track. According to another aspect, the wall panel storage system includes a corner drive mechanism with a contact element configured to contact a wall panel to change a direction of travel of the wall panel as the contact element runs along a curved guide.

A movable partition system that can include branched overhead rails where movable panels, such as glass doors, wall panels, are guided along the branched overhead rails by path guides positioned with the overhead rails. The guide paths are shaped and aligned within the overhead rails to provide a smooth transition at the junction between overhead rails. The combination is suitable for use with both right-angle and oblique angle branched overhead rails.
