Definitions

  • the folding three-dimensional reticular structure of the invention comprises a system of rods pivotally connected to each other by couplings which can be distributed by unfolding over a three-dimensional space and be folded until the rods and their coupling connections form a compact bundle which is easily manageable in general and for transport in particular.
  • the assembly of rods and connecting couplings forms one whole which is joined together permanently, even during foldmg.
  • Each rod has three seatings or sockets for an equal number of articulating pins provided on the couplings, the pins being mounted in the seatings in parallel coplanar positions. That is, the rods are articulated at each of the associated couplings and the number of the associated couplings connected to each rod is always three, two of them at the ends and a third at an intermediate point the spacing of which from the other two seatings depends on the curvature which the structure has when unfolded.
  • the couplings take the form of cores equipped with similar projecting arms disposed at equal angles in one plane, and they are provided as upper, lower and intermediate couplings.
  • End couplings of the same kind are connected permanently by flexible stays or ties operating under tension which, while they do not render folding difiicult, limit the amplitude of extension or opening by their predetermined length.
  • both systems of stays or one only, and in this case preferably the upper one, may be replaced by a piece of strong fabric associated with the corresponding couplings.
  • bracing action which prevents folding when the structure is to remain open is achieved by means of another series of stays, these being disengageable, which connect end couplings of difierent kinds, that is upper ones with lower ones.
  • the extended structure adops the form of a curve (a shell-shaped configuration); that is to say that the couplings of the same designation are found upon one of its three curved surfaces, concave towards the interior of the covered enclosure.
  • FIGURE 1 is a plan view of a portion of an open structure in accordance with the invention.
  • FIGURE 2 is a fragmentary view in elevation of the same structure
  • FIGURE 3 shows in detail the connection of three rods of the structure toan intermediate coupling
  • FIGURE 4 shows in perspective view one of the intermediate connecting couplings
  • FIGURE 5 is a longitudinal section of an endcoupl-ing for the rods, showing one rod mounted and one of the stays limiting opening of the structure,
  • FIGURE 6 is a perspective view of the end coupling shown in FIGURE 5,
  • FIGURE 7 shows in elevation a rod for the embodiment illustrated in FIGURE 1,
  • FIGURE 8 is a plan view similar to FIGURE 1, in this case of an embodiment comprising rods bent-at their intermediate couplings in a plane normal to that determined by the axes of rotation about the couplings,
  • FIGURE 9 is-a perspective view of a connecting part for end couplings in accordance with the embodiment of FIGURE 8,
  • FIGURE 10 illustrates a specimen of the bent rods of that embodiment
  • FIGURES 11 and 12 are perspective views showing perspective views showing progressive steps in opening or unfolding the FIGURE 1 structure in which a cover sheet has been substituted for the cables a.
  • each rod B (as illustrated in FIGURE 7) is always articulated to three couplings 1, 2 and 3.
  • the rod B which is straight and in one piece, has three bores or seatings, two end seatings 1' and 3' and one intermediate seating 2', which are coplanar and extend at right angles to the longitudinal axis of the rod. It is essential that the three seatings should be parallel as shown. 7
  • the distances I2' and 2 -3 vary according to the curvature of the erected structure, considered as a covering. When these distances are equal a plane covering is obtained, as can be seen in FIGURE 2.
  • FIG. 1 Assembly of the combination of rods is commenced by grouping a predetermined number thereof on a central coupling element, as shown in FIGURE 4.
  • the element comprises a core 2 provided with three arms'4, 5 and 6.
  • the number of the arms may vary, depending on the desired geometrical form of the contour of the structure.
  • three-rod couplings result in a hexagonal peripheral boundary or contour whenthe structure is unfolded.
  • the use of four-armed couplings result in unfolded structures having quadrangular contours, or peripheral boundaries in a horizontal plane.
  • the embodiment illustrated in the corresponding drawings has, with its three rods per coupling, a hexagonal contour as seen in FIG. 12.,
  • the arms projecting from the core 2 must be equal and regularly distributed in a common plane, and at the end couplings there must meet a number of rods B equal to that meeting at the intermediate couplings.
  • the core 10 is covered at one end by a movable sleeve 14 and terminates in threaded pins 15 and 16.
  • FIGURE 5 The general reference 1-3 appearing in the upper right-hand part of FIGURES 5 and 6 indicates that the elements shown therein represent, without distinction, the form taken by the couplings 1 and 3.
  • a folding assembly is formed the extension of which is limited in amplitude by the cables a and b.
  • cables 0 which connect upper and lower couplings to one another in pairs of different kinds. These cables 0 are permanently attached to one of the couplings forming the pair and are attached to the other coupling -at a suitable time by connecting to engaging means which can be manipulated easily and rapidly.
  • engaging means which can be manipulated easily and rapidly.
  • FIG- URE 2 possible hooking on to the lower couplings has been assumed as the most convenient arrangement.
  • the rods B do not have their axes coincident at the end coupling 1 and 3, and
  • FIG- URE 10 marked with thereference B and in this figure the references 1'1, 2' and 3' correspond to the parallel seatings for the axes of articulation.
  • FIGURE 9 The connecting parts for the end couplings are replaced by other parts similar to that shown in FIGURE 9, which is formed by a prismatic core 18 from which project pairs of parallel pairs of lugs 19. These lugs project at equal angles in the same general plane and have bores 20 for the insertion of articulating bolts.
  • assembly is carried out by placing each pair of lugs at the end of a rod with an articulating bolt passing through the rod seating, and not, as previously described, by connecting the rod laterally.
  • a folding three-dimensional reticular structure comprising a plurality of rods pivotally connected at their upper and lower ends by couplings to one another to form an assembly of rods which is foldable and extensible, each rod being articulated at at least three points respectively located at both ends of the rod and at an intermediate point, each rod having substantially parallel articulation axes corresponding to said articulation points and located in a plane common to the axis of the rod, said couplings being positioned at the said points of articulation of each rod and having cross arms to each of which a rod is pivotally joined for articulation, flexible elements interconnecting the upper couplings and similar flexible elementsinterconnecting the lower couplings to prevent extension of the assembly beyond a preselected limit while permitting the assembly to fold into a compact form with all the rods adjacent each other, and stays releasably attached between upper and lower couplings of different rods to prevent folding and impart rigidity to the unfolded reticular structure.
  • a folding three-dimensional reticular structure according to claim 1 wherein the couplings connected to the rods at their intermediate points are positioned at unequal distances from the ends of each rod and the rods are arranged so that branches of equal length are positioned on the same side of the intermediate couplings.
  • a folding three-dimensional reticular structure according to claim 1 wherein said rods are each bent out of a plane at right angles to said articulation axes at the point where the intermediate coupling is located, said bent rods permitting assembly of the structure so that the axis of each portion of the rods meeting at upper and lower couplings coincides effectively with the center of the intermediate coupling, bending moments thereby being avoided in the couplings.
  • a folding three-dimensional reticular structure according to claim 1 wherein said stays are applied near the peripheral border of the unfolded structure so as to prevent contraction thereof, a plurality of straight legs supporting the structure and connected to couplings spaced 7 6 inwardly from said peripheral border, the said stays extending outwardly from the couplings to which the legs are connected.
