Abstract
A frame suitable for use in a cradle for small children, or in similar devices, where a structure for containing a dynamic load requires support, consists of two flexible longitudinal laminae, parallel one to another and joined by one or more crosswise laminae. The longitudinal laminae are curved in a more or less central part of their length so forming a first section that rests on the ground and a second section inclined at an angle determined in relation to the first section to sustain the containing structure. In the curved part and along the whole of the second section the longitudinal laminae are subjected to torsion opposite in sign such as to incline them towards the inside of the frame; this lessens their flexibility sufficiently to limit elongation of the flexor oscillations.
