<p>A frame (2) is formed from a continuous piece of rigid material and reversibly convertible between a substantially flat configuration and a three-dimensional supporting configuration for an object (8). In its three-dimensional supporting configuration, the frame (2) is resiliently deformable so that the arms (6a, 6b) stand out of the plane of the base portion (4) to support an object (8) connected to the arms (6a, 6b). The continuous piece of rigid material automatically returns the frame (2) to its flat configuration when an object is not connected to the arms (6a, 6b) to provide a counter-force holding the frame (2) in the three-dimensional supporting configuration.</p> |
