  • the novel grille frame element illustrated therein is of hexagonal configuraion.
  • the major surface area of the grille element 1 has a substantially square portion 2 which merges at two oppsite sides thereof with respective triangular portions 3, 4.
  • the dimension 0 identifies the length of the sides of the square 2 and of the hypotenuse of the triangles 3, 4.
  • the tips of the triangles, the corners where the square portion 2 merges with the triangular portions 3, 4. and the sides of the square portion 2 which extend from one to the other of the triangular portions 3, 4, are all provided with arcuately curved inwardly directed 1, illustrating a further recesses 5 which, when they face similar recesses of adjacent ones of the elements 1, as shown in FIG. 2, form passages through which connecting elements can be extended to connect the elements together.

  • the hexagonal grille elements 1 are provided in the illustrated embodiment of FIG. 1 with reinforcing webs or portions 7 which are of arcuate configuration. Similar rein forcing portions or webs 7aare shown to be of straight configuration in FIG. 3, and of angular configuration in FIG. 4 where they are identified with reference numeral 7b.
  • FIGS. 5, 6 and 7 show exemplary embodiments of connecting means for connecting the adjacent grille elements together.
  • edge portions of the grille elements may be provided in the regions of the recesses 5 with notches 8 of the illustrated part-circular configuration or of any desired other configuration, into which projections 9, 10 or 1 1 of the connecting elements can extend (compare FIGS. 5-7 to provide for a more rigid mechanical connection of adjacent grille elements with one a nother.
  • FIG. 5 a screw connection is provided, the screw or bolt having a head 12 which is formed with an annular projection 9 adapted to extend into the notches 8, and a similar projection 9 can be formed on the nut 13 which cooperates with the threaded stem of the screw.
  • the screw is identified with reference numeral l4 and the nut with reference numeral 15.
  • the head of the screw and the nut have interposed between themselves and the hexagonal grille elements 1 respective washers 16, 17 on which the projections 10 are formed which are to extend into the notches 8.
  • FIG. 7 A further possibility is shown in FIG. 7, wherein the nut (the screw is not shown) is identified with reference numeral 18 and provided with a recess 19 into which a profiled washer 20 extends, having a projecting edge portion 11 which is to be received in the respective notches 8.
  • the grille elements can be connected not only at their various corners, but also intermediate these corners.
  • the connection intermediate the corners can be established with a frame 21 (see FIG. 2) which can be a partial frame or a complete frame surrounding the ornamental grille assembled from a plurality of adjacent ones of the hexagonal grille elements.
  • brackets 22 are placed onto the frame 21, for instance so that they embrace it, as shown in FIG. 2, and they are formed with recesses 23 corresponding to the recesses 5, and may be formed with notches 24 corresponding to the notches 8.
  • the recesses 23 can cooperate with recesses 5 of adjacent ones of the grille elements 1, to again form passages through which the various threaded connectors can be extended.
  • brackets 22 may, but need not, be made of synthetic plastic material, although this is a currently preferred material, especially a synthetic plastic foam material such as polyurethane foam or the like.
  • the grille element, and the grille assembled from the same, is stable even if made of synthetic plastic material.
  • FIGS. 8, 9 and 10 show that if the grille element is provided with weakened portion 26 located as shown in FIGS. 8-10, it is a simple matter to sever triangular parts 25 from the grille element, and to discard the remainder of the element. These triangular portions 25 can then be combined with grille elements of the configuration shown in FIG. 1 to assemble various different ornamental grilles.
  • This particular construction has the advantage that only a single type of grille element need be produced, requiring only a single type of mould, rather than having to produce the grille element of FIG. 1 and additionally to produce triangular grille elements such as those shown in FIG. 10.
  • FIGS. 11, 12, 16 and 17 show ornamental grilles assembled exclusively of the grille elements 1 shown in FIG. 1, with the aid of appropriate connectors. It will be clear from a consideration and comparison of these FIGS. that the invention provides for a very substantial variety in the ways in which the grille elements can be assembled.
  • FIGS. 13, 14 and 15 are assembled from combinations of the grille elements 1 of FIG. 1 and the grille elements 25 of FIG. 10.
  • FIGS. 13, 14 and 15 are assembled from combinations of the grille elements 1 of FIG. 1 and the grille elements 25 of FIG. 10.
  • cover plates or center wall portions can be provided.
  • FIG. 18 shows an embodiment wherein the grille element 1 may be provided on one or both sides (shown only for one side) with a cover plate 28.
  • This may for instance be of translucent or transparent material, such as synthetic plastic and is advantageously provided with recesses 29 which can cooperate with the recesses 5 to permit the passage of the connecting elements, and with projections 30 which extend into the notches 8 of the associated element 1.
  • the plate 28 need not be transparent or translucent, but could instead be opaque.
  • FIG. 19 finally shows another embodiment wherein the grille elements are identified with reference numeral 31 and are made of synthetic plastic foam material, for instance a polyurethane foam or the like.
  • the grille elements are provided substantially midway between their opposite major sides with a substantially plate-shaped wall 32 which is connected with or of one piece with their circumferential wall and provided with ornamental shapes 33, 34 on one or both of its sides. These shapes 33, 34 of course also serve as reinforcements for the wall 32.
  • the connection of these grille elements 31, or of the ones shown in FIG. 18, is carried out in the same manner as previously described.
  • An ornamental grille comprising a plurality of adjacent hexagonal grille frame elements located in a common plane, each of said grille frame elements consisting of a hexagonal wall composed of two opposite parallel lateral wall portions of predetermined length located at a distance from each other which is equal to said predetermined length, and two pairs of end wall portions at the opposite ends of said opposite parallel lateral wall portions, the end wall portions of each pair being of equal length and inclined towards each other and forming a right angle with each other, each of said hexagonal grille frame elements being provided at least at all six corners thereof with an arcuate recess which extends inwardly in direction of said hexagonal wall and which has an open side facing similar recesses in adjacent ones of said elements defining with said similar recesses a passage through said ornamental grille; connecting means extending through the respective passages and connecting said adjacent elements together in an interlocked relationship forming said ornamental grille; and a plurality of ornamental reinforcing portions, each extending between respective ones of said adjacent end wall portions and reinforcing the latter
