Embodiment Construction

[0023] refer to figure 1 To figure 4, the universal joint has four grooves 2, 2', 2", 2'' on a larger surface that coincides with the sides, so that it can receive a tubular member that is not shown in the figure and that extends articulated On the surface 3 of the universal joint with four grooves (2, 2', 2", 2''), there is an opening 4 for fixing the end of the tubular extension member 5, and another not shown in the figure with the corresponding The tubular member connected by the universal joint can slide in the opening 4. Along the edge of said face of the universal joint is a groove 6 constituting the base for receiving the end 8 of a spring 9 as shown in FIG. 4 .

[0024] The two ends of the spring 9 are embedded in grooves on the non-matching surfaces in the two joints of the two overlapping members so that the coupled members remain fixed. After the member is inserted into said groove by the end 8 of the inverted spring 9, the spring is easily inserted and remains l...

Abstract

Composite structures obtained by joining two or more structures of the type which presents pairs of joined tubular elements (5), whose extremity is hinged in universal joints and in which the universal joints are substantially parallelepiped in form and present four seats of hinging corresponding to the sides faces, in which said universal joints present grooves (6) along the sides of the face, in which are scheduled the seats to hinge the extended elements, in proximity of the edges and parallel to the same edges, that cooperate with C-sectioned fixing elements (9) to hold united two matched universal joints belonging to two structures from join.

Description

technical field [0001] The present invention relates to collapsible structures composed of interconnected, elongated tubular members. Background technique [0002] In particular the invention relates to a portable foldable structure that can be deployed horizontally or vertically and can be used for displaying products or as a support for raised loads such as platforms, subgrades for walkways, technical pavements, lecture halls, stands , a box, the structure comprising a number of interconnected parallelepiped units, the sides of which are secured by a pair of tubular members interconnected by cross-links. In these constructions, each end of an elongated tubular member comprising a pair of cross-connectors is pivoted into an articulated universal joint, also of parallelepiped shape. One of the larger surfaces of the universal joint has hinged seats corresponding to each side, thereby receiving the four end portions of the tubular member. If the structure has to bear larger...
