The guy wires are preferably secured to the extendable and retractable tower at first and second connecting positions that are displaced from one another about an outer perimeter. Methods of deploying the mobile tower are also disclosed.

A shelter system having a stationary section configured to be positioned below grade and having a plurality of perimeter walls forming a stationary frame. A plurality telescoping sections are nested within the stationary section. A roof panel is attached to a top telescoping section of the plurality telescoping sections. A lift system is configured to provide a vertical force to the top telescoping section such that the plurality of telescoping sections are selectively positionable between an idle configuration below grade and a raised configuration above grade.

A support structure comprising a pultruded outer beam (12), a pultruded inner beam (14), a plurality of wear tabs (16) affixed to the inner beam, and a gear track (18) affixed to the inner beam. The outer beam is substantially hollow and adapted to receive the inner beam and the inner beam is shaped so that a portion of the inner beam extends nearly the entire height of the outer beam and a portion of the inner beam extends nearly the entire width of the outer beam, the plurality of wear tabs are located at one or more corners of the inner beam, and the gear track contacts a gear for facilitating movement of the inner beam.

A modular wall may include one or more units. Each unit may include a telescopic member having an inner end and an outer end. The telescopic member may include a base, located at the inner end; a capital, located at the outer end; and a shaft disposed between the inner end and the outer end. The shaft may include one or more sections. Each shaft section may include an outer circumference, the outer circumference of each shaft section may decrease from the outer end to the inner end.

An expandable roof system (100) for an expandable vehicle, trailer (200) or transportable unit, comprises a fixed roof component (10), a first moveable roof component (20) and a second moveable roof component (30). The first moveable roof component (20) is mounted above the fixed roof component (10), and the second moveable roof component (30) is mounted above both the fixed roof component (10) and the first moveable roof component (20). The first moveable roof component (20) is arranged for lateral movement between a stored position in which it overlies the fixed roof component (10) and a deployed position in which it is laterally offset from a first side (16) of the fixed roof component (10). The second moveable roof component (30) is arranged for lateral movement between a stored position in which it overlies both the fixed roof component (10) and the first moveable roof component (20), and a deployed position in which it is laterally offset from a second side (11) of the fixed roof component (10).

A containerized, transportable, pre-engineered, pre-fabricated, pre-assembled, adjustable, structural modular building system is disclosed, comprising a plurality of structural modules comprising a plurality of horizontal structural decks and vertical structural frames to be used in building construction. The building system is transportable world-wide using existing standardized ISO shipping methodologies of truck, train and shipping vessel. The structural modules may be expanded and contracted to vary the height, length, and width of the structural module based on building specifications. In such, the structural modules may be used for buildings having various floor dimensions, and may form self-contained structural elements within the building structure. In a single module configuration, the bottom horizontal structural deck is positioned between a first side deck and a second side deck. The first and second side decks are each rotationally engaged to each side of the bottom deck to form a building module. A track system slidingly engages with a plurality of structural frames and includes a locking mechanism to retain the plurality of structural frames in position along a length of the each of the bottom deck, the first side deck and the second side deck. A plurality of corrugations affixed to each of the bottom deck, the first side deck, and the second side deck to form a surface whereon concrete is poured.

In a structure, for example in the form of a trailer cabin (115), which structure is advantageously provided for connection to a vehicle (103), the following are provided as sliding segments: a number of horizontal sliding segments (201) slidable in an expansion direction, vertical sliding segments (136) slidable in an extension direction at a right angle to the expansion direction, and double sliding segments (139) which are slidable both in the expansion direction and in the extension direction and which are connected to a central fixed segment (403). Thus, when the sliding segments (136, 139, 201) are transferred from a pushed-together compact position into a pulled-out expansion position, an interior space of the structure (115) can be considerably enlarged by a usable space in comparison with a minimum volume in the compact position.

A collapsible shelter comprising a rigid-framed box section and a plurality of rigid panel sections, wherein each panel has a complimentary shape and dimension to fit within a neighbouring section such that the structure can be collapsed to form a storage case when all the panel sections fit within the box section.
