Abstract:
A shelter assembly has a frame having a plurality of tillable support members, each having a hollow portion for receiving a filling material. The support members are configured to form a structure wherein the support members form walls of the structure. The shelter assembly has a plurality of columns which form corner posts of a structure and a plurality of walls which are removably attached to a pair of adjacent columns. The walls have support members to which at least one panel is attached. The support members are secured to a pair of adjacent columns via fasteners. An upper portion forms a roof of the structure wherein the columns are attached to coupling members of the upper portion.
Abstract:
The present invention relates to a cover assembly including a frame including at least one inflatable portion. At least one cover is supported by the frame to define a chamber. Adjustment means is provided for adjusting the air conditions (e.g. pressure or oxygen content) of the pressure chamber.
Abstract:
A flexible, inflatable shelter is held within a storage container. The shelter can be erected rapidly, by directing compressed gas held or produced within the container, into the flexible material which will define the finished shelter. Personnel using the shelter then enter through an air lock door located in the storage container. An air lock may be alternatively provided such that is is located at least partly within the deployed shelter, and so that it does not occupy substantial space in the container. The container includes supplies necessary to sustain life for an extended period. The shelter can be used to protect personnel from harmful environments caused by accidents or explosions in mines, tunnels, industrial plants, and the like. The container is compact, but allows rapid deployment of the flexible material to produce a shelter which is of approximately the same volume, or greater, than that of the storage container.
Abstract:
A hinged door (26) is provided for a tent (20). The hinged tent door (26) in one embodiment includes a frame (46) for supporting the outer edges of the door. The hinged tent door (26) may include a removable frame (46) so that the door may be folded along with the tent into a compact configuration for storage. As an example, the frame (46) may be one or more poles (48, 50) that are removably attached to the door.
Abstract:
A shelter (1) for means of transport, particular campers, is described, comprising an inflatable supporting structure (2) and a waterproof covering sheet (3) supported by the inflatable supporting structure (2), so as to form a shelter beneath which the means of transport is placed.
Abstract:
Embodiments include an inflatable support structure enclosing a region fillable by a fluid at a positive pressure above an atmospheric pressure. A flexible screen is attached to the support structure, a region between the flexible screen and the support structure fillable by a fluid at a negative pressure below the atmospheric pressure that holds the flexible screen in a shape suitable for image projection. A method according to embodiments includes inflating an inflatable support structure with a fluid at a positive pressure above an atmospheric pressure and removing fluid from a region between the support structure and a flexible screen attached to the support structure to hold the flexible screen in a shape suitable for image projection with the fluid at the negative pressure below the atmospheric pressure between the flexible screen and the support structure.
Abstract:
The invention relates to the provision of a structure which can be moved from a storage position to an in-use position. The structure is attached to a further building (8) which means that when the structure is moved to the in-use position the structure forms an additional area for the further building. In one preferred embodiment persons entering the further building are required to pass through the structure first, thereby allowing, for example, in a medical environment, the persons to be decontaminated prior to entering the further building.
Abstract:
A construction system of a plurality of interlocking construction elements is disclosed. At least one of the interlocking elements is a cured-in-place element (10) having a pliable exterior shell defining a cavity and a strength-imparting core placed inside the cavity. The system also includes a hardenable media for filling the cavity. The exterior shell of the cured-in-place element is adapted to expand as its cavity is filled with the hardenable media or as the hardenable media cures, whereby the interlocking elements bond into an integral structure (30) by an interference fit or a friction fit. Methods of construction of new structures and reinforcement of preexisting ones are also disclosed.
