A portable erectable shelter may include a pair of wall panels arranged outermost from a pair roof panels. The pair roof panels may be between the pair of wall panels in a collapsed, vertical position of the shelter. The portable shelter may include a first outer wall truss link rotatably fixed to a sidewall of a first wall panel and having a first end pivotally secured to a first corner of a first roof panel and a free end opposite the first end. The portable shelter may further include a first outer roof truss link rotatably fixed to a sidewall of the first roof panel and including a first end pivotally secured to a first corner of the first wall panel. The first end of the first outer wall truss link may be arranged to abut the first end of the first outer roof truss link in an erect position.

A dynamic hinge mechanism that connects frame elements of a foldable apparatus such as for example a children's play-yard or other folding containment or structure, including an elastic element that applies a biasing force to assist in erecting the apparatus from a folded configuration to an expanded configuration.

A transportable garage is provided, for storing vehicles, aircrafts, equipment, or shelter individuals on a site. The garage comprises a frame assembly configurable between a collapsed configuration and an erected configuration. The frame assembly comprises support members extending along the ground when the garage is use; and a plurality of frame units connected to the support members. Each frame unit comprises a plurality of articulated frame members, which are configurable between a folded configuration and a deployed configuration. The garage may also include a covering assembly for covering the frame assembly when in the erected configuration. When the frame assembly is in the collapsed configuration, transportation of the garage to the site is facilitated.

A supporting frame for aerospace applications comprises a plurality of rods, which are arranged along two bases substantially parallel and opposite each other, and along two sides, which are substantially parallel and opposite to each other and are coupled to each other via the two bases; the rods are coupled to each other in a mutually rotating manner by nodes so as to be able to configure the supporting frame between a deployed operating condition and a compacted operating condition; the nodes are spaced apart from one another in the deployed operating condition and are each hinged to at least two of the rods; in the compacted operating condition, each of the nodes is placed side by side with two adjacent nodes so as to form, together, two supporting members arranged at opposite longitudinal ends of the supporting frame and each being ring-shaped.

An extendable arm structure includes: an upper extendable arm and a lower extendable arm which extend parallel in a same direction; and a vertical coupling member that couples the upper and lower extendable arms. Each of the extendable arms includes a plurality of X-shaped cross units each formed by pivotally coupling two rigid members via a middle coupling shaft, and two end coupling shafts that pivotally couple ends of adjacent ones of the cross units. The extendable arm structure further includes: a planar member that closes, in a planar fashion, a space between the rigid member of the upper extendable arm and the rigid member of the lower extendable arm which extends parallel to the rigid member of the upper extendable arm in a same direction.

The present invention relates to a portable building assembly providing a complete structure configured for onsite construction. The structure once packed down can be delivered to site in a flat packed form most efficient for transportation.

A collapsible modular building is constructed from at least two building modules that are joined together to form the building. Each building module is constructed to be configured in either a collapsed or erect position. In the collapsed position, each module is individually transported to a site by trailer. Once offloaded, the modules are joined together to form the building, this joining together of the modules can be done while the modules are in the collapsed position or in the erect position.

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.

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.

[Problem] To provide a foldable frame structure, unfoldable into a 2N-sided polygonal shape (N being an integer equal to or larger than 2), achieving a securely and rigidly supported unfolded state and a compact folded state. [Solving means] 2N upper rods (210), with an equal length, are coupled to each other to define a planer 2N-sided polygonal shape. First coupling means (220) coupling two adjacent upper rod (210) at a corresponding one of apices of the 2N-sided polygonal shape, and holding the two upper rod (210) in such a manner that the upper rod (210) are rotatable about an orthogonal axis orthogonal to axes of both of the two rods and rotation means (240) that enable each of the upper rods (210) to rotate about the axis (AX1) are provided. Folding to be a columnar shape as a whole can be achieved with the upper rods (210) pivoted about the orthogonal axis (AX2) to minimize an angle between two adjacent upper rods (210) while the upper rods (210) are rotated about the axis (AX1).
