Folding, dismountable and telescopic structure

Abstract

The present invention is a folding and telescopic structure that consists of two parallelograms (1) (2), which can be flattened in opposite directions, located on the same plane and joined articulately by two springs (17) from its front (3) and back (4) jambs. These jambs (3) (4), which are “U” shaped and hollow, allow the end (5) and intermediate (6) crossbars to lodge inside to totally occupy the space available inside the hollow jambs. The end crossbar (5) has a groove (8) in which to slide a first shaft (9) of the back jamb (4) at the same time that a it can turn counter-clockwise upon a second shaft (10) of the front jamb (3) . The intermediate crossbar (6) 15 moves in a similar way, but the hinge (13) that receives the second shaft (12) is not fixed on the intermediate crossbar (6), but can be slid across it. FIG. 1.
