Definitions

  • the present invention relates to a body, e.g. a pavement tile or a tile in general of the kind defined in the preamble of claim 1.
  • the object of the invention is primarily to eliminate problems occuring with conventional tiles because of separation in the horizontal and vertical directions and the accompanying risk for stumbling and severe personal damages.
  • the interlocking effect is achieved by the alternating bewelling of the sides of the tile on all four sides, so that they will grip into each other in all three dimensions.
  • the bewelling is limited to about 10 degrees, and the horizontal arcuate form does not constitute more than about 5 % of the area of the tile, and thus it will have substantially the same appearance as a conventional tile despite the fact that it interlocks.without any further structural elements or binding agent.
  • US,A,1,969,729 relates to an element which could be used as a tile.
  • the element has on each of its sides a series of convex and concave edges meeting each other on each of said sides, another set of convex and concave edges meeting each other on each of said sides are arranged on a lower plane than the first mentioned set of convex and concave edges.
  • the respective convex and concave edges on one side of the element being offset with respect to the other respective convex and concave edges on the same side of the element. All faces are vertical and at right angles to the top plane of the element.
  • the convoluted edges are formed by axis of cylinders and square shoulders are formed between each concave portion and corresponding convex portion of the other section.
  • a joint is always a joint and the distance between the tiles can never be zero, and therefor, and also of practical reasons, like sand, dirt, etc., the tile has irregular sides, and this also because otherwise it would not have been possible to lay it in the alternating jointing which is necessary for the interlocking effect, as will be discussed further in the detailed description of the invention.
  • This solution makes it possible to have a jointwidth within relatively wide limits.
  • the design of the tile simplifies the construction work, since the tile is relatively unsensitive to the ground support, i.e. the tiles can be laid directly on a relatively flat soil without extensive preparations using sand or asphalt.
  • the tile according to Fig. 1 e.g. a pavement tile (tile in general) or wall tile (outdoors or indoors), is geometrically formed in such a way that above and underneath half the thickness, on each side, are convex bends with radius R2 which, at approximately the middle of the side 5, Fig. 3, change over to concave bends with radius R1.
  • the sides In a vertical cross-section the sides have the form of two vertically opposed circular curves r1 and r2, respectively.
  • the vertical curvature r1, r2 is zero in all four corners from where they increase continuously towards their maximum at the maximum of the horizontal bends with radii R1 and R2, which is approximately at one quarter and three quarters, respectively of the side of the tile with "H" as a starting point and from there return to zero at the approximate centre point of the tile, at 6 in Fig. 3, and the corner of the tile, 4 in Fig. 1, respectively.
  • the chosen distance between tiles, or in other words the jointwidth will be the same throughout the sides, in all three dimensions.
  • the Y-side is described with reference to Fig. 1 where H is a reference corner.
  • H is a reference corner.
  • the Y-side lower part (underneath a line marking half of the thickness) begins with a convex circle segment 1, the bending of which (R2) has a maximum value at approximately a quarter of the length of the side (A) and from there the radius again returns to zero at the approximate centre point (2) of the side, and then changes into a concave circle segment (3) where the radius equals R2 plus the desired jointwidth.
  • the maximum of the bending of the concavity (R1) occurs at approximately three quarters of the length of the side, counting from H, and return to zero at the corner 4, which is also a straight corner like H.
  • the side of the tile is made up of two half circle segments standing against each other, r1, r2 (cut section A-A in Fig. 1), where r2, counting from H is zero, and hereby forms the straight corner H.
  • the circle bow r2 has its given vertical maximum in the same point as the lower convex circle segment with radius R2 has its maximum point A ( cut section A-A), and the vertically standing concave circle bow r1 opposite r2, starts in the same way from the coner H, at zero, and has its concave maximum where the upper concave circle segment with radius R1 has its maximum A, and return to zero at approximate the centre point of the tile, and changes over along the line 5-5 in Fig.
  • the X-side of the body can be described in the same way, starting from H.
  • the other X-side and Y-side starting from h to H can be described in the same way.

    caractérisés en ce que
    les parties courbées sont formées comme segment de cercles, les parties courbées vers l'intérieur ayant un rayon R1 et les parties courbées vers l'extérieur ayant un rayon R2, R1 étant plus grand que R2, la différence correspondant à la largeur de joints ;
