If an element 4 is slightly expanded due to temperature changes, the width of the element may change. If the width increases, the edge of the tongue 4.2 of the element 4 ( Figure 3d ) moves towards the fastening member 1 and may push the protrusion 1.9. Due to the flexibility of the protrusion and/or the wall 1.2, the protrusion 1.9 and/or the wall 1.2 may slightly move. However, the movement does not affect to the next element because the locking section 1.10, 1.11 which is towards the adjacent element is also capable of bending when necessary.
  • Thermal expansion may also affect the length of the elements 4.
  • the fastening members 1 are not screwed or attached with an adhesive with the elements 4, wherein the fastening members 1 allow the elements to slightly "slide" in the longitudinal direction.
  • some means may be provided.
  • a tape 9 ( Figures 3a and 3b ) having a frictional surface may be fixed on one transversal support rail 2a-2c, wherein the elements 4 are installed on the frictional surface of the tape 9.
  • An advantageous location for such tape 9 is in the middle of the elements 4 in the longitudinal direction i.e.
  • a tape having a surface with less friction may be attached with the other transversal support rails 2a, 2c to improve the slideability of the elements 4 on the surface of the support rails 2.
  • This kind of arrangement may assure that the middle of the elements 4 remains at substantially the same location despite of the thermal expansion whereas the ends of the elements 4 may move more easily.
  • the tape may also improve the locking effect because the tape may be slightly elastic so that it can be compressed when inserting an element under the locking section 1.10, 1.11 and decompressed when the element 4 has been inserted. Moreover, manufacturing tolerances of the elements 4 may cause that the height of the tongue of the element 4 may vary in the longitudinal direction of the element 4. Thus, the tape may reduce a possible effect of this variation.
  • one or more pieces of tape may be installed on one or more support rails 2a-2c to dampen sound i.e. to be used as a sound insulation irrespective of whether the above mentioned friction effect is utilized or not.
  • one or more anti-skid devices 10 may be used to prevent or reduce sliding of the elements 4, as is illustrated in Figure 7 .
  • the anti-skid device 10 may comprise a bottom section 10.1 and one or more side sections 10.2a, 10.2b.
  • the side section(s) 10.2a, 10.2b may have a toothed edge or similar structure which is adapted to make a contact with the element 4 which is installed above the anti-skid device 10.
  • the toothed edge grips to the bottom surface of the element 4 and therefore prevents or at least reduces lateral movement of the element 4 with respect to the support rail 2.
  • the anti-skid device 10 may be attached with the support rail 2 with one or more screws, for example.
