Abstract
A frame structure having collapsed and erected conditions and comprising a plurality of rigid frame sections (21) hingedly connected one to another by hinges (23). An erection means is provided for effecting relative pivotal movement between the frame sections to erect the frame structure. The erection means comprises at least one cable (39) having one end thereof connected to one of the outer frame sections (21a) and the other end thereof fixed to a power device (40) connected to the other outer frame section (21a) whereby operation of the power device to tension the cable effects movement of the outer frame sections in a direction towards each other.
Claims13
A method of erecting a frame structure comprising the steps of positioning end to end first and second rigid frame sections and at least one rigid intermediate frame section positioned between said first and second rigid frame sections, pivotally connected together at their adjoining ends, in a generally horizontal relationship;
- guiding a cable through cable guideways located upon each rigid frame section, spacing at least one of the cable guideways apart from the rigid frame sections and supporting each cable guideway which is spaced apart from the frame sections on an arm mounted on, and extending downwardly of, the rigid frame sections;
- securing one end of said cable to said first rigid frame section;
- and, tensioning the other end of said cable at the second rigid frame section, thereby effecting relative pivotal movement between adjacent pivotally adjoined frame sections, raising said intermediate section off of the ground, and erecting the frame structure.

- guiding a cable through cable guideways located upon each rigid frame section, spacing at least one of the cable guideways apart from the rigid frame sections and supporting each cable guideway which is spaced apart from the frame sections on an arm mounted on, and extending outwardly of, the rigid frame sections;
- securing one end of said cable to said first rigid frame section;
- and, tensioning the other end of said cable at the second rigid frame section, thereby effecting relative pivotal movement between adjacent pivotally adjoined frame sections, raising said intermediate section off of the ground, and erecting the frame structure.
