A variable shape three-dimensional structure includes: an upper frame (10); a lower frame (20); and a longitudinal coupling member (30) that couples the upper and lower frames. Each of the upper and lower frames includes cross units and an end coupling portion. Each cross unit is formed by two rigid members crossing each other in an X-shape and pivotally coupled together. The end coupling portion pivotally couples the ends of the rigid members of the cross units. The longitudinal coupling member (30) includes a bent unit comprising a first and second bent rigid members (31,32), and a bent portion coupling shaft (33). The first and second bent rigid members are bent in a V-shape. The bent portion coupling shaft pivotally couples the bent portions of the first and second bent rigid members. The upper end of the bent unit (30) is coupled to the upper frame (10) and the lower end of the bent unit (30) is coupled to the lower frame (20).

A locking mechanism (10) for a hinge (4) is disclosed. A latch member (11) engages with a lip (12). A positive drive means (20, 23, 24, 41) enables the latch member to be driven into and out of engagement with the lip. The driven engagement when the hinge is used in relation to columns (1, 101) prevents small movements at the hinge being magnified into large movements at the end of the column members. The driven dis-engagement enables the hinge to be opened notwithstanding mechanical loads, corrosion, insect nests and similar obstacles. The drive means preferably takes two forms, namely threaded fasteners (20, 23, 24) and a spring loaded rotatable actuator (41) with ramped surfaces (48, 49) which male with ramped surfaces (61, 62) on the latch member (11).

Modular transfigurable drilling rig system composed of multiple components, which system is transfigurable between a transport mode in which the components of the system are transportable and an operational mode in which the components are assembled to a drilling rig which is adapted to drill into a well centre in the ground.

Building construction supported by the ground, having a floor, sidewalls mounted upon the floor and a roof supported by the sidewalls and the floor. A plurality of spaced apart inflatable flexible elements are provided which are disposed between the floor and the ground. Adjustable linkages anchor the floor to the ground and serve to urge the floor toward the inflatable flexible elements to provide a stable and relatively level support for the floor as well as the sidewalls and roof.

The edge of a side wall (23) of a cabin is brought into engagement with a floor (25) or roof (16) and retained there by extrusions (35, 36), one (35) of which is secured to the floor, while the other (36) - secured to the edge of the side wall (23) - slides up a ramp (48), over a plateau (38); and into a valley (59) formed on the one extrusion. In the engaged position (Figure 9), there is horizontal location [possibly using an added stop (43)] and only limited freedom of relative vertical movement by virtue of cooperating hooked portions (45, 46) on the two extrusions. A shelf (47) opposes entry of moisture. The engagement means, and the hinge of Figures 4-6 enable a cabin to be bult from pre-formed panels by hinging and pivoting.

Es wird ein Verbindungselement für Platten beschrieben, das aus U-förmigen Aufnahmeklammern (1, 2, 15) besteht, die untereinander zu einem Knoten zusammensetzbar sind. Jede Aufnahmeklammer ist dabei mit einer Scharnierhülse (12) versehen, deren axiale Länge nur einem Bruchteil der in Richtung des Verbindungssteges gemeßenen Höhe entspricht. Diese Scharnierhülsen (12) können mit weiteren Scharnierhülsen (12', 12b) anderer Aufnahmeklammern über einen die Scharnierachse bildenden Befestigungsbolzen (13) fluchtend zusammengesetzt werden. Diese Ausgestaltung weist den Vorteil auf, daß alle Aufnahmeklammern (1, 2, 15) mit den daran befestigten Platten im beliebigen Winkel zueinander eingestellt werden können, so daß weitgehend Freiheit in der Anordnung der zusammenzuhaltenden Platten gegeben ist.
摘要:
This invention is a hinge for joining two panels together edge to edge, for example, in making a folding cabin. The two hinge components (11, 12) each define a panel recess (21, or 22) and a hinge recess (23 or 24) separated by a partition (17 or 18). Scrolls (22 and 26) in the hinge recesses can be fitted together by longitudinal sliding, and then co-operated to form the hinge, and also form a kind of labyrinth seal against moisture penetrating across the hinge. The partitions (17 and 18) protect the edges of panels in the panel recesses from moisture. The hinge can be used in a method of building a cabin from large but light heat insulating panels (31). Roof ridge panels 41 and 42 are hinged together at 43 and pushed up to the ridge position by being slid along the upper edges 73 of end walls 54 and/or by being guided over and pivotting on the upper edge 72 of a partition 46.
