A tent frame (1) for carrying a tent cloth comprises at least four rods (2) each configured to have one end (3a) resting on a ground, to extend from that end convergingly towards a top of a said tent and to carry a tent cloth bearing outside thereon, and an arrangement (6) configured to interconnect said rods (2) so as to hold them in a determined mutual position. Said arrangement (6) comprises, for each pair of adjacent rods (2a-b), at least one rigid elongated element (7) and at least two elongated members so as to provide support for holding said rigid elongated element (7) between the adjacent rods (2a-b) and these in a said determined mutual position.

A method for on-site assembly of a shelter for an above-ground structure to protect the structure from blast, wind, fire or other physical hazards. A pyramidal shelter with triangular or rectangular base is formed by joining side panels to each other. Each side panel includes a triangular frame covered, except at access hatch, observation port and door openings, with either steel plate or diamond steel mesh to which blast-resistant, fire-resistant or other kinds of coatings or panels are applied. A corner anchor assembly to support each corner of a shelter has a lower plate, an overlying split plate, and a pair of upstanding, anchor rods attached to the split plates for insertion into hollow, lower portions of side beams of adjacent side panels. The corner anchor assemblies facilitate expansion of an assembled shelter by addition of more modular components.

A foldable or non-foldable trampoline includes a frame assembly that supports a resilient trampoline mat using a plurality of springs. The frame assembly includes an adjustable tension system that adjusts a dimension of the frame assembly. For a circular frame assembly, the adjustable tension system may increase the circumference of the frame assembly to increase a tension of the springs. The adjustable tension system may also decrease the circumference of the circular frame assembly to decrease a tension of the springs.

The invention provides means, methods, and devices for suspending persons and goods above the ground while outdoors. Particularly, the invention provides a treepod assembly having a tent and a suspension element, capable of securely supporting at least one occupant while suspended above the ground from a tree or other elevated structure. In some embodiments, the treepod assembly may further include a rigid frame for additional support. Certain embodiments include an inflatable pocket that protects occupants and items inside the tent from injury or damage in case of a fall and impact with the ground.

Trampolines may include a frame, a bounce mat coupled to the frame, and a plurality of poles coupled to the frame. A cover may be disposed over at least a portion of the bounce mat and retained in an at least partially suspended position utilizing the plurality of poles. Trampoline may be utilized by coupling a bounce mat to a frame. A plurality of poles may also be coupled to the frame. A cover may be disposed over at least a portion of the bounce mat utilizing the plurality of poles to retain the cover suspended over the at least a portion of the bounce mat. Other aspects, embodiments, and features are also included.

The invention provides a building assembly comprising a subterranean cellar defining a space to be formed under the ground, the cellar having a ceiling including a first opening defining an access region for a staircase to connect the ground of the subterranean cellar, when in situ, with the surface of the ground above the cellar; and a heat control device having a heat transfer mechanism to provide heat from the cellar to a region on the ground above the cellar.
