An electronic device and method are disclosed. The electronic device includes a housing defining an opening, a driving actuator, a slide door moveable to selectively cover and expose the opening, a link connecting the slide door and the driving actuator, the link linearly moveable in accordance with a driving operation of the driving actuator to move the slide door, a forcible open blocker that is moveable to restrict opening of the slide door when the opening is closed, and to release blockage of the opening of the slide door based on a linear movement of the link, and a processor. The processor implements the method, including: receiving an external input signal and identify whether to expose or cover the opening based on the external input signal, and activating the driving actuator to expose or cover the opening according to a result of the identification.

A wall panel includes a first upright post, a second upright post, an upper stretcher connecting the first upright post to the second upright post, a lower stretcher connecting the first upright post to the second upright post, and a frame having an extrusion profile, wherein the extrusion profile is configured to couple the frame to the wall panel frame. A wall panel assembly includes a plurality of the wall panels.

An assembly for a vehicle includes a front pillar and a rear pillar spaced along a vehicle-longitudinal axis. The front pillar and the rear pillar define a door opening. The assembly includes a first track supported by the front pillar and a second track supported by the rear pillar. The assembly includes a lower bar and an upper bar movable upwardly relative to the lower bar along the first track and the second track. The upper bar is movable between a lowered position and a raised position. The assembly includes a crossmember pivotally coupled to the lower bar and the upper bar.

A movable wall panel system may include a bottom drop seal assembly that maintains a constant force relative to a floor portion of an environment through a damper. The movable wall panel system may include an automatic top seal assembly that seals a gap between the movable wall panel system and a ceiling of the environment. The moveable wall panel system may include multiple panels and a plurality of seals positioned between adjacent panels to seal a gap between the adjacent panels.

A carriage (10) provided with one or more pairs of wheels (14) for moving sliding door (42) is arranged in a sliding seat (44) of an extruded profile (28), made of aluminium or other suitable material and fixed to a wall (48) or ceiling (54). The extruded profile in which the carriage (10) is arranged comprises opposite side walls (30, 32), oriented orthogonally with respect to the upper base (34) and with respect to the lower base (36) of said profile; on said lower base a central slot (38) extending longitudinally is made for the passage of a stem (40) projecting downwards in the direction of the door (42) to which it is connected. The carriage (10) comprises a support body (12) made of plastic, metal or other suitable material, constituting the load-bearing frame of said carriage to which the pairs of wheels (14) are connected, with rivets (16); each of the wheels is paired with an elastic element (20) placed in a recess (24) made along the opposite sides of the support body (12).

A museum showcase includes a guide system for a sliding door, including upper and lower guide mechanisms. The upper guide mechanism includes primary and secondary rails. The upper guide mechanism also includes a first slide unit and a second slide unit. The first slide unit has a rolling member on an upper horizontal track of the secondary rail, and a sliding block engaged on a vertical track of the secondary rail. The second slide unit has a rolling member on a lower horizontal track of the primary rail, and a sliding block engaged on a vertical track of the primary rail. Thereby, the upper guide mechanism is extremely strong. The weight of the door, entirely supported by the secondary rail, is discharged on the first rail by the two slide units to transmit both vertical and horizontal loads.

The sliding door system includes a sliding door, displaceable along a running rail relative to a stationary activation member up to a closing position; which includes a door leaf equipped with an activatable sealing device including an extractable sealing strip and actuating element equipped with a transmission device including a transmission element; and includes at least two carriages, including a carriage body and running elements connected to the door leaf, and are held in the running rail displaceable in parallel to the longitudinal axis of the running rail; wherein the activation member and transmission device are arranged so that, when the sliding door enters the closing position, a force can be transmitted from the activation member via the transmission element to the actuating element in order to drive out the sealing strip. A stationary buffer device stops the sliding door in the closing position and includes the activation member.

An indexing multi-panel door includes a leading door panel supported on a first track and moveable between open and closed positions, a trailing door panel supported on a second track and moveable between open and closed positions, a motion control track mounted to one of the door panels, a follower mounted to the other one of the door panels, the follower including a first distal end received within the motion control track, the motion control track including features to frictionally engage the first distal end, wherein when the leading door is moved between the open and closed positions, engagement between the first distal end and the features moves the trailing door panel along with the leading door panel, and allows slippage, wherein the leading and trailing door panels move relative to one another as the leading and trailing door panels are moved between the open and closed positions.

A roller including: a main body portion configured to include an outer ring and a rotatable inner ring on an inner circumferential side of the outer ring; and a covering portion disposed on an outer circumferential surface of the outer ring, the covering portion being made of a synthetic resin in which reinforced fibers are dispersed, wherein the covering portion includes a region in which arrangement directions of the reinforced fibers are aligned.
