Roller assemblies for hanging panels are disclosed herein. Roller assemblies according to the present disclosure are configured to support a hanging panel and include an elongate rail configured to be mounted on a surface. The roller assembly includes a trolley assembly, which includes a bearing assembly configured to translate the trolley assembly along the elongate rail and a bracket coupled to the bearing assembly and configured to be coupled to the hanging panel. The elongate rail includes a rail adjustment system configured to facilitate adjusting a position and/or an orientation of the elongate rail with respect to the surface. The rail adjustment system is concealed in a rail-assembled configuration, and includes at least two spaced-apart rail adjustment mechanisms.

A system for reversibly providing a wall, comprising: a first panel comprising first track followers on each of opposite side edges of the first panel; a first pair of tracks adapted to receive the first track followers and that are generally vertical on opposite sides of a space, each comprising: a top at a point overhead, and a lower point part-way to the floor of the space; a second panel comprising: upper second track followers on sides of the second panel near a top edge of the second panel, and lower second track followers on sides of the second panel near a bottom edge of the second panel; wherein, as the first panel is lowered, the first track followers ride in one of the first pair of tracks until at least one first track follower reaches the bottom of the one of the first pair of tracks, thus allowing the first panel, when lowered, to form a first portion of the wall; a second panel comprising: upper second track followers on each of opposite side edges of the first panel proximate to a top edge of the second panel, lower second track followers on each of opposite side edges of the first panel proximate to a bottom edge of the second panel; a second pair of tracks that are generally vertical on opposite sides of the space to be divided and generally parallel to the first set of tracks, each comprising: a top at a point overhead, a junction where a spur track separates from the second track, a spur track at a point part-way to the floor that angles over from the second pair of tracks to a point below and in vertical alignment the first pair of tracks, a bottom at a point at or above the floor, wherein the lower second track follower interacts with the toggle switch, as the second panel is lowered, to move the toggle switch from a first position to a second position, and wherein the lower second track follower interact with the toggle switch, as the second panel is raised, to move the toggle switch from the second position to the first position; wherein the toggle switch, when in the second position, diverts the upper second track follower from the second pair of tracks into the spur; wherein the bottom of the second track is in vertical alignment with the first track; wherein, as the second panel is lowered, the lower second track followers reach the bottom of the second pair of tracks and the upper second track followers reach the bottom of the spur, thus allowing the second panel, when lowered, to form a second portion of the wall; and a toggle switch at the junction of the second track having a first position such that a track follower in the second track will continue past the junction remaining in the second track and will move the toggle to

A movable wall panel system is disclosed. The movable wall panel system may include at least one monitoring system to monitor at least one area adjacent the movable wall panel system. The movable wall panel system may include a touch screen as part of an operator interface.

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.

Disclosed is a sliding door or window. The sliding door or window includes a door/window frame, a swing fastening mechanism is disposed at a lower end of a side of the door/window frame, and a locking structure is mounted on an upper end of the side of the door/window frame. The swing fastening mechanism and the locking structure are each provided with a snakelike groove inside which a shaft operative to slide along a groove orientation is arranged. A handle disposed on the door/window frame is operative to drive the shaft to slide in the snakelike groove, thereby forcing the swing fastening mechanism or/and the locking structure to swing.

A system for reversibly dividing a space is disclosed. Independent panels, with track followers attached to both narrow sides, move along parallel tracks. The panels start in an overhead storage space. The tracks are shaped such that as the panels move from the storage space into the space to be divided, one panel stops higher and the next panel slides down and then under the first panel. These panels preferably form a single-plane divider in the space.

A folding panel system that allows foldable panels, such as folding glass doors, to fold and move around segmented tracks. The system includes a trolley assembly. The trolley assembly can include a pair of dual roller assemblies spaced rigidly apart by a rigid guide member and supported by an overhead guide track. The rigid guide member is positioned outside of the guide track and moves lengthwise along the overhead guide track except between overhead linear track segments. A hinge extension is secured to and extends rigidly away from the rigid guide member vertically away from the guide track. This configuration holds the hinge extension at a constant angle with respect to the guide track. The hinge extension pivotably joins hinge leaves from adjacent panels hingedly joining the two panels.

Movable partitions may include leading end assemblies comprising an articulated leading member. The articulated leading member may be coupled to a support trolley, and at least one coupling between the articulated leading member and the trolley enables the articulated leading member to move relative to the support trolley. Methods of operating a movable partition include displacing a portion of a leading end assembly to align a majority of at least one surface of the leading end assembly with a portion of an adjacent structure.

Various embodiments of the present disclosure relate, generally, to a control system for a movable partition. In one embodiment, the control system is an access control system that includes a lock control interface and a remote line interface at which lock modes are asserted, and which are communicated to a door controller. Protocols installed at the controller enable the controller to provide control signals to the movable partition responsive to the various lock modes asserted at the lock control interface and remote line interface.

Disclosed is a modular building system including, in some embodiments, one or more wall panels, one or more floor panels, and one or more roof panels. The modular building components of the modular building system including the one or more wall panels, the one or more floor panels, and the one or more roof panels can form housing or storage structures with electrical wiring, plumbing, or both wiring and plumbing. The housing or storage structures can be erected by one or more persons without a need for a plumber, an electrician, or power tools. Also disclosed is a method for erecting one or more housing or storage structure in accordance with the modular building system.
