A deployable structure includes a structural mechanism consisting of a plurality of rigid links 1 connected together by rotational joints 2 to form an array of Bennett linkages 20. The Bennett linkages 20 are interconnected so that the structural mechanism, including all the Bennett linkages 20, has a single degree of mobility. The structural mechanism has a profile with a curvature that varies during movement to deploy the structure from a state in which its profile is flat to a state in which its profile is curved. This allows is very convenient as the structure may be assembled, stored and/or transported in the flat state, prior to deployment into the curved state. As such the structure has many application including the frame for a tent.
