Abstract:
A portable enclosure for temporary shelter purposes as a storage building or workshop at remote construction sites, comprising:a towable boom having coupling means at a first end for coupling to a towing tractor, and having wheels at a remote second end so that said towable boom maybe towed over roads and worksite terrain; a plurality of articulable frames, each comprising at least a first frame member, a second frame member, a third frame member, and a fourth frame member; and a plurality of fluid operated extendible cylinders mounted on each articulable frame; wherein a first cylinder is mounted between said boom and said first frame member of each articulable frame so as to adjust the angular disposition of said first frame member with respect to said boom; wherein a second cylinder is mounted between said second and third frame members of each articulable frame so as to adjust the angular disposition thereof with respect to each other; wherein each said first cylinder operates to move its respective first frame member from a first, tilted position with respect to said boom, to a second, substantially vertical orientation; wherein each said second cylinder operates to move its respective second and third frame members from a first position whereat an acute angle is formed between said second and third frame members to a second position whereat the angle formed between said second and third frame members is greater than said first position angle; and wherein each said fourth frame member is articulated to its respective third frame member so as to depend in a downwardly direction from the end thereof remote from its connection to the respective second frame member, whereby said fourth frame member will assume a substantially vertical orientation when said second and third frame members have assumed their respective second positions; whereby each of said respective first and fourth frame members of each frame is articulable to a substantially vertical orientation, and so as to be horizontally distanced one from the other, and so as to constitute a storage or workshop space therebetween.
