Abstract
A perfected articulated hammer of those made up of two tubular U-shaped frames equipped with cross-braces that allow them to fold, to which another main frame, with a visor, is articulated, on which the determining surface of the seat rests and of the backrest, essentially characterized by the fact that each of the joints is constituted by a common core embedded transversely, on which the tubular frames have the possibility of turning and folding, by virtue of separate orifices of a larger diameter made in their zone of unión and provided with a small peripheral fence that establishes the convenient adjacency between frames and hides the central zone of the nucleus on which they revolve; having provided that the visor is constituted by two parallel arcuate pieces that support in the extreme middle area an integral surface, being linked to the main frame with turning movement, in such a way that its displacement allows to regulate the field of the shadow that projects.
