In one example, a double jointed hinge connects a blow molded plastic door and a blow molded plastic wall panel. The double jointed hinge includes a first hinge element that defines a first axis of rotation, and the first hinge element is connected to the blow molded plastic wall panel, a second hinge element that defines a second axis of rotation and is connected to the blow molded plastic door, and the second hinge element is spaced apart from the first hinge element, and a first link and a second link, the first link and the second link connecting the first hinge element to the second hinge element.

A movable wall system includes a plurality of movable wall panels including a first movable wall panel and a second moveable wall panel rotatably coupled together through at least one hinge. The movable wall system further includes a biasing system which biases the first movable wall panel and the second movable wall panel into an arrangement wherein a panel face of the first movable wall panel and a panel face of the second moveable wall panel are generally parallel.

Improved systems and methods for operating moveable architectural elements (e.g., furniture) are described. The system can include improved features implemented throughout various elements, including hardware elements, controller elements, and/or software elements. As one example, the system can feature the ability to map a characteristic load profile across a particular length of actuation and, if during operation a measured load exceeds the profile, adjust (e.g., stop) the system's motion. The system can also advantageously map its current draw to increase energy efficiency. In addition, the system can include a positioning system that enables it to automatically determine its position upon start up and during operation. In some implementations, the system includes multiple moveable elements (e.g., furniture items). In some cases, power is distributed to the moveable element(s) using a moveable power distribution module. Many other improvements and features are contemplated and described.

A leading end assembly for a movable partition may include a frame, an exterior skin coupled to the frame for covering a leading surface and two opposing side surfaces of the frame, the exterior skin including a leading member forming at least a portion of a leading surface of the leading end assembly and at least two side members, each side member being formed separately from the leading member and forming at least a portion of a lateral side portion of the leading end assembly. Movable partitions may include leading end assemblies and leading end assemblies may be formed by related methods.

A fixation device for limiting a gap between a first construction component and a second construction component relative to which the first construction component is movable has first and second fitting parts attached to the first and second construction components, respectively. The first fitting part has a fixation projection with first end and opposed second end. The first end is pivotable about a fixation axis fixed at the first construction component. The fixation projection is pretensioned so as to pivot the second end away from the first construction component. The second fitting part has a guiding surface and a holding element. Fixation projection and guiding surface interact such that, when the construction parts are moved toward each other, the second end glides along the guiding surface toward the holding element and catches therein. A folding device of construction components is provided with such fixation devices.

The present invention provides a wheel assembly having an elongate housing configured to engage with and support a sliding panel element. The housing has a first subassembly having a first pair of wheels, the first subassembly being configured so as to allow rocking of the first pair of wheels. The housing also has a second subassembly having a second pair of wheels, the second subassembly being configured so as to allow rocking of the second pair of wheels. The first and second subassemblies are independently vertically adjustable with reference to the housing. The present wheel assemblies may be of the type used to support a sliding door or similar, on a surface such as a track.

A folding device as room closure has a frame and a chain of panels arranged therein. The panels are pivotably connected by alternate first and second hinge arrangements and foldable from a stretched-out closed position into an open accordion fold arrangement. First hinge arrangements are guided on guide rails of the frame; second hinge arrangements are deflected away from the frame. In the closed position, the panels are sealed relative to each other and to the frame by frame seals extending at least partially along a sealing plane. An adjusting strip in front of a lateral frame part is adjustable to adjust a spacing between adjustable strip and lateral frame part for spatial adaption to an adjacent panel. The adjusting strip has a sealing contact surface aligned with the sealing plane and resting against a seal arranged on the lateral frame part and extending into the guide rails.

A movable wall system includes a plurality of movable wall panels including a first movable wall panel and a second moveable wall panel rotatably coupled together through at least one hinge. The movable wall system further includes a biasing system which biases the first movable wall panel and the second movable wall panel into an arrangement wherein a panel face of the first movable wall panel and a panel face of the second moveable wall panel are generally parallel.

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.

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 faun 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.
