Collapsible structures are disclosed. In one embodiment, the collapsible structure includes a plurality of hinges and a plurality of panels. The plurality of panels are swingably connected by the plurality of hinges so as to form at least one arch when the collapsible structure is in an erected state and so as to become at least one stack of the plurality of panels in a collapsed state. The panels allow for the collapsible structure to maintain its structural integrity when erected but to have a compact and transportable configuration when collapsed.

To provide a foldable structure to which stiffness is imparted so that non-uniform extension and contraction is inhibited even when each surface is formed of a flexible material, a manufacturing method and a manufacturing device of the foldable structure, and a non-transitory computer-readable computer medium storing a program. A foldable structure including at least two tubular structures in which the two tubular structures include a shared surface array which is continuous shared surfaces shared by each other, and a twisting characteristic in the shared surface array of one tubular structure is in a direction opposite to that of the twisting characteristic in the shared surface array of the other tubular structure.

Foldable tubular construct/element with one rigid degree of freedom is of a tubular construction formed by a number of single layered annular units which are connected in sequence; each single layered annular unit is of a prism having N ridge lines; two adjacent prisms each having N sides are connected to each other by sharing a polygon with N sides formed on an intersection plane; each prism with N ridge lines is composed of N rigid planar quadrilateral facets; two adjacent single layered annular units comprise N spherical mechanisms formed by the intersections of only four planar quadrilateral facets at each apex, where N is a number greater than 3.

A flexible article is provided having a core formed from a plurality of laminar panels that are inter-connected to provide an expandable structure upon movement of the panels away from each other. Opposite ends of the core terminate, in a pair of end panels whereby the end panels may be moved apart to expand the expandable structure. Each of the panels are made from wood material. The panels, for example, include two wood sheets with longitudinally oriented grains and a flexible backing sheet that is sandwiched and adhered between the two wood sheets.

Collapsible structures are disclosed. In one embodiment, the collapsible structure includes a plurality of hinges and a plurality of panels. The plurality of panels are swingably connected by the plurality of hinges so as to form at least one arch when the collapsible structure is in an erected state and so as to become at least one stack of the plurality of panels in a collapsed state. The panels allow for the collapsible structure to maintain its structural integrity when erected but to have a compact and transportable configuration when collapsed.

A modular deployable shelter for camps, comprising a body made of a flexible material, which can be deployed from a transport position to a position of use, generating an inner trapezoidal living space with a roof at an angle, characterized in that, in the position of use, the shelter comprises a rigid roof plate which closes the upper part of the body when in the deployed position, forming a ventilated space; wherein the floor of the body is closed from the bottom by a rigid floor plate; and wherein the right and left sides of the flexible body, in the position of use, have a longitudinally reinforced bellows structure, also being closed at the front and rear part thereof by rigid panels, the front panel having an opening which defines the entrance of the living space in the deployed position thereof; and wherein the sides of the body, in the deployed position thereof, have panelled reinforcements containing a reinforcement material.

The invention relates to a cleanroom and a method for rapidly providing a cleanroom, having a first shell wall, which separates a first space that is indirectly or directly adjacent to a floor area, having a flexibly foldable shell wall directly facing the first space, which is made exclusively of at least one air-permeable material suitable for cleanrooms, from a second space surrounding the shell wall, and comprises at least one support element supported on at least one of the floor areas and at least one hanging element provided on the shell wall, having a mobile fan-filter unit, which has an air inlet area and an air outlet area and is outside the first space, and a supply line comprising a material for cleanrooms and connecting the air outlet area to the first space bounded by the shell wall arrangement.
