Definitions

  • the present invention relates to folding structures consisting of interconnected extended tubular elements. More particularly, the present invention relates to portable folding structures which can be extended horizontally or vertically, that can be used for product display or as supports for raised loads, such as for instance platforms, walkway bases, technical pavements, rostrums, stands, boxes, comprising a plurality of interconnected parallelepiped cells in which the sides faces of the parallelepiped are defined by a pair of tubular elements interconnected by a scissors-connector. In these structures each extremity of the extended tubular elements which constitute the pair of scissors-connected elements, is inserted by rotation into a seat in an articulated universal joint, also parallelepiped in form.
  • the universal joint presents, on one of the larger faces, a hinging seat corresponding to each side face, and can therefore accept up to four extremities of tubular elements.
  • a variation to the embodiment described above has been used for some time in which the universal joints provide for a fifth seat on the surface of said face into which is fixed a tubular element, within which another tubular element of smaller diameter is inserted as a sliding fit and whose extremity is inserted into the face of a similar universal joint.
  • the tubular element inserted into the face of the universal joint is fixed and is stopped against the opposed joint into which is inserted the extremity of element that slides inside.
  • This system also presupposes complex and onerous setting-up operations, as well as relatively long dismantling and assembly times.
  • USP 5,123,550 discloses collapsible lightweight frameworks consisting of substantially square modules disposed in side-by-side and/or super imposed relationship.
  • One purpose of the present invention is provision of a simple and rapid method of joining two or more structures of the type consisting of pairs of extended tubular shear-connected elements, whose extremity is hinged in universal joints and in which the universal joints are defined integral with equal and parallel larger faces and are preferably substantially parallelepiped in form and present four hinging seats set in one of the larger faces near a side face.
  • a second purpose of the present invention is the coupling of two or more superimposed structures of the type described above that furthermore present in the inside surface of the face of the universal joint, in which are seats for the hinging of the tubular elements, a fifth seat into which is fixed the extremity of an tubular telescopie extention element whose other extremity is fixed to the opposite underlying universal joint.
  • a further purpose of the present invention is a device that allows the coupling of the aforesaid structures.
  • the purposes of the present invention are achieved using the composite structure as disclose in claim 1
  • the purposes of the present invention are achieved using the universal joint described above that present grooves along the sides of the face, in which are scheduled seats for lodging the tubular elements in proximity to the edges of the type and parallel to the same edges, that cooperate with C-sectioned fixing elements (in the following also refered to as the C-shaped spring or C-spring) to hold two matching universal joints belonging to two superimposed structures together.
  • the C-shaped fixing elements are substantially rectangular sheets of flexible material with two opposite edges folded and inverted.
  • the folded and inverted edges of the C-shaped spring present dimensions and forms corresponding to those of the grooves cut into the faces of the universal joints.
  • the C-shaped springs with inverted edges cover most of the corresponding side faces of the superimposed universal joints and they could provide for, in some cases, grooves in correspondence with seats of lodgement of the tubular elements and they could take different configurations depending on their use.
  • the C-shaped springs could be applied to all the side faces of all the joints that are matched in the overlap or in coupling of multiple structures.
  • the faces of the matching joints could present one or more suitable- perforations for the housing pivots that prevent any movement of the joints on the contact pivot.
  • the universal joint 1 presents four seats 2,2',2" and 2"' on one of its larger faces in correspondence to the side face, that could accept hinged extended tubular elements not shown in the figure
  • grooves 6 which constitute seats to accept one of the extremities 8 of a C-spring 9 as shown in figure 4.
  • the insertion of the two extremities of the C-spring 9 into the grooves on the non-matching faces of two joints belonging to two superimposed structures allows the coupling of the structures to be maintained fixed.
  • the insertion of the springs is easily achieved after the structures have been superimposed by snapping the inverted extremities 8 of the C-springs 9 into said grooves, where they remain locked.
  • the operation of dismantling is performed quickly, for instance, by removing one of the two inverted extremities 8 of the C-springs from the groove.
  • Figure 5 shows a preferred embodiment of the invention. This provides for the use of universal joints whose face opposite to that in which the grooves have been made contains the opening 10 that can accept pivots 11 that prevent any relative movement of the joints in the horizontal plane.
  • Figure 6 shows a side view of a support system for elevated loads according to the invention, obtained by joining two structures.
  • the said figure shows the tubular elements 12 joined with scissors-connection and hinged in seats 2 of the universal joint, as well as the extendible telescopie tubular elements 5, that assure resistance to loading of the structure.
