Abstract: The present invention comprises a core 1 formed by rigid sections 2 which alternate with flexible sections 3, supplied with flexible strips 4, 4a, 7, 7a, which tend to recover their position when bent transversally along either of their larger faces. The bar also incorporates a covering formed by a layer of plastic material 9, two tapes 10 and 11, which are wrapped firmly around it, and which produce friction between the strips and the opposing faces of the core 1. The bar bends transversally at the regions occupied by the flexible sections 3. The presence of rigid sections 2 gives greater resistance to the bar, while the two tapes 10, 11 provide the friction between the strips 4, 4a, 7, 7a necessary to keep stable the bends produced in the bar.

Abstract: The supporting bar, which could serve as a supporting arm for an articulated table lamp, is constituted by a plurality of thin, flat straps of elastic material which are juxtaposed in close contact and held pressed together within an outer cover, with sufficient force that when the bar is flexed, the frictional forces from cover and strap to strap maintain the bent shape, against the elastic forces tending to restore the unbent shape of each strap. One of the straps can be made of magnetized material and the others of ferromagnetic material.
