An extendable arm includes first and second rigid members forming a cross unit. Each rigid member includes one end portion including one of end coupling shafts, the other end portion including the other end coupling shaft, and a middle portion including a middle coupling shaft. The one end portion of each rigid member includes a bottom-side outer side surface that surface-contacts a base surface when the extendable arm in an extended state is placed thereon. The other end portion of each rigid member includes a top-side outer side surface extending parallel to the bottom-side outer side surface of each rigid member. The middle portion of each rigid member includes a middle strip region passing through a middle coupling shaft and perpendicular to the bottom-side outer side surface and the top-side outer side surface.

The present invention provides a construction set suitable for creating a variety of structures and includes a plurality of elements. A modular construction system includes hubs which are embodied as solid-surfaced hexahedrons having at least one flanged protrusion on at least two faces of each hexahedron. Adjacent structural bodies in the modular construction system may be connected to as few as one face of a hub, or to as many as all six faces, by means of attachable connector elements. The hexahedron at the core of the hub may be of the same or larger dimensions relative to the cross-section of the framing materials (e.g., lumber, tubing, composites, metals, extruded members) it connects.

The disclosure relates to a prefabricated movable photosensitively adjustable solar bionic landscape pavilion capable of being disassembled and constructed quickly. The landscape pavilion comprises a support structure, a ceiling, a movable platform, a linkage system, a lighting system, and an energy system. The support structure is arranged at the center of the movable platform and forms large-area shelter space with the ceiling. The ceiling may rotate around the support structure in the height direction of the support structure, so as to be unfolded or folded. The movable platform is a base of the landscape pavilion, undertakes the support structure and the ceiling above the movable platform, and meanwhile, provides fixing space for the linkage system, the lighting system, and the energy system.

A beam system and method of erecting a supporting arch enables large roofed structures to be erected quickly and economically. The method includes aligning a plurality of structural elements longitudinally; connecting upper corners of the structural elements to upper corners of adjacent structural elements, wherein adjacent lower corners of the structural elements remain unconnected; elevating first and second structural elements in a middle of the supporting arch; connecting lower corners of the first and second structural elements together; elevating third and fourth structural elements adjacent the first and second structural elements, respectively; and connecting lower corners of the third and fourth structural elements to lower corners of the first and second structural elements, respectively.

The assembly may comprise a guide assembly comprising a guide member and an engagement member moveably engageable with the guide member.

A shape-morphing space frame (SMSF) utilizing the linear bistable compliant crank-slider mechanism (LBCCSM). The frame's initial shape is constructed from a single-layer grid of flexures, rigid links and LBCCSMs. The grid is bent into the space frame's initial cylindrical shape, which can morph because of the inclusion of LBCCSMs in its structure. The design parameters include the frame's initial height, its tessellation pattern (including the unit cell bistable elements' placement), its initial diameter, and the resulting desired shape. The method used in placing the unit cell bistable elements considers the principle stress trajectories. Two different examples of shape-morphing space frames are presented herein, each starting from a cylindrical-shell space frame and morphing, one to a hyperbolic-shell space frame and the other to a spherical-shell space frame, both morphing by applying moments, which shear the cylindrical shell, and forces, which change the cylinder's radius using Poisson's effect.

The invention relates to a fold-out prefabricated construction structure and method for the assembly thereof. The structure, having bays of desired width, length and shape, is made up of porticos formed by pillars and an upper structure (27). The method involves positioning the base (1) on a surface (28) and provisionally fixing at least one portion of said base. This allows opening the porticos with the help of auxiliary structures created for this purpose (14). The elements of the structure are fixed to one another, and to the surface of the portions of the base in their final position. Each of the porticos not yet fixed must be moved to their final position, in a successive manner and separately from the closest fixed portico, together with the rest of still free attached porticos, and suitably fixed to the surface.

An assembly for converting motion comprises a first arm and a second arm rotatable about first and second spaced apart fixed pivots; a third arm pivotably connected the second arm at a position spaced apart from the second fixed pivot; a first connecting arm extending between and pivotably connected to the first arm and the third arm; a second connecting arm extending between and pivotably connected to the first arm and the second arm; and a third connecting arm extending between and pivotably connected to the first arm and the third arm. The assembly may be used to move and support components of a building.
