Definitions

  • the present invention has as object a precision system which includes at least one precision device, such as a knob, for use in an assembly for spacing and levelling tiles during their laying.
  • at least one precision device such as a knob
  • knock in this description refers to an element that can be manipulated by a user during the tile laying phases, alternatively known in the sector as "tie rod”.
  • tiles is to be understood as including in this description all types of flat elements capable of forming a floor, not excluding briquettes, and the like.
  • the laying of tiles involves the laying of an adhesive material on the surface to be covered and the subsequent arrangement of the tiles according to a desired geometry. In the vast majority of cases, space is left between adjacent tiles, commonly called "gap".
  • One of the most difficult operations to perform during installation is to align the tiles correctly, i.e. to ensure the consistency of the gaps between adjacent tiles.
  • Another complex operation is to create a correct planar arrangement of the tiles, in order to guarantee a constant level of the covering surface.
  • a first device, made from two plastic components, is shown for example in patent application WO2009/022359 .
  • the first of these components consists of a base to be placed on the surface to be covered with tiles.
  • the base has a cross-shaped appendix (or linear or half-cross appendix) on the inside of which are placed the corner portions of four contiguous tiles.
  • the thickness of the arms of the cross determines the width of the gaps between these tiles.
  • the tiles are arranged parallel to each other and spaced constantly. From the centre of the cross of the appendix, a threaded column or stem develops upwards.
  • the second component consists of a tightening knob (or tie rod), the knob being centrally pierced and threaded and attached to be screwed on the column threaded of the base.
  • tie rod or knob or the part of the device used to screw the threaded base, fully covers the view of the gaps underneath the tiles, thus not allowing the user to be sure that the work is well done, even forcing it to make continuous unscrewing to ensure that the tiles are perfectly matched.
  • a main purpose of the present invention is to allow the user to have a complete view of the work that is being done, giving the possibility to the same, to carry out a much more precise work in the shortest time possible.
  • Another purpose of the present invention is to describe a device that allows a faster and more precise positioning of the same during the work phases.
  • a further important purpose of the present invention is to propose a device that allows to significantly reduce the working times with obvious economic saving in terms of working hours for those who commission the installation and consequent saving of time for the user.
  • an innovative precision tile laying system comprising at least one knob for use in an assembly for spacing and levelling tiles during their laying, comprising at least one threaded stem adapted to be positioned at the crossing of two or more tiles, wherein said innovative knob comprises at least one body provided with at least one top surface with a thickness in which at least one hole is formed, said hole comprising a threaded portion at least to engage with said threaded stem, said threaded stem being treated with polishing and chroming to present a low surface roughness to allow less friction when screwing the knob hole with said threaded stem, so the knob self-screwing on said self-threaded stem to the base of the threaded stem getting in contact with the tiles.
  • This hole includes at least further notches to allow the quick coupling of this knob on said threaded stem, to allow a quick coupling of said knob on said threaded stem and therefore on said tiles; in this case the knob is pushed directly along the body of the threaded stem until in contact with the surface of the tiles without screwing the knob on the threaded stem, but forcing it into place, thus achieving a rapid forced sliding.
  • the knob is pushed directly along the body of the threaded stem until in contact with the surface of the tiles without screwing the knob on the threaded stem, but forcing it into place, thus achieving a rapid forced sliding.
  • the variants may not be included in the same production variant.
  • the body of this knob is at least partially transparent.
  • This knob also includes, in a position opposite to said top surface, a perimetral edge configured with a surface capable of coming into contact with the said tiles.
  • a further significant advantage of the present invention is, as mentioned, the possibility of quick coupling of the innovative device described in the present invention.
  • the body of said knob is substantially completely transparent.
  • precision system in the top surface of the precision device or innovative knob, defined from now on for convenience only knob, are obtained said flexible fins preferably defined by notches, where said flexible fins are designed to enlarge the hole during the tightening phase of the knob, in this case, in a preferred form of realization, the thickness of the top surface, which will also be the thickness of the fins obtained from them, can be realized so as to give flexibility to the movement of insertion of the knob of the stem, so in some forms of realization can be for example less than the form of realization with a hole including a thread as described above.
  • the threaded portion inside the hole is configured in such a way as to allow the tightening of the leveling screw for the tiles by making, for example, only one half turn of the knob.
  • the material in which the body is made e.g. of a "cup" shape is preferably chosen from transparent virgin polypropylene, polycarbonate, transparent polystyrene, polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polyvinyl chloride (PVC) or combinations thereof, or other materials suitable for the purpose.
  • Figure 1 shows, in perspective view, a particularly preferred form of realization of the precision system and in particular of the knob 10 according to a preferred realization of the present invention.
  • Knob 10 is suitable for use in a system for spacing and levelling 20 tiles during their installation.
  • Knob 10 is intended to be used in cooperation with a base 30 equipped with a threaded stem; this set of elements is also referred to here as "leveling screw”, so that this innovative precision system includes at least said knob 10 and said base 30 comprising at least said threaded stem.
  • the base 30 and the threaded stem are known in themselves in the field and in Figure 3 is represented for simplicity only the trace of the base 30 under the tiles 20 during the laying.
  • Knob 10 comprises a body 12 with a top surface 14 in which a hole 16 is cut.
  • the body 12 of the knob 10 has a substantially "cup” conformation and is equipped with an external surface in which there are highlighted relief portions 13 and recessed portions 13' to facilitate the grip of the knob 10.
  • flexible fins 15 defined by notches 17 are provided, wherein the above flexible fins 15 are designed to enlarge the hole 16 during the tightening phase of the knob 10.
  • a threaded portion 22 that allows the tightening of the leveling screw for tiles 20.
  • This threaded portion preferably of thickness S, as shown in detail in fig. 4 ; in a particularly advantageous way, the threaded portion 22 in an embodiment form can be made to engage with the threaded stem, said threaded stem (not represented here because it is known in itself) is in the present form of construction however advantageously treated with polishing and chrome to present a low surface roughness to allow as little friction as possible when screwing the hole 16 of knob 10 with said threaded stem so that the knob 10 in a particularly advantageous and innovative way self-tightens thanks to its weight on said threaded stem independently up to the base of the threaded stem in contact with the tiles.
  • the threaded portion 22 inside the hole 16 is configured in some embodiment forms in a particularly advantageous way so as to allow the tightening of the leveling screw for tiles 20 by making only half a turn to the knob 10.
  • the cup body 12 includes, in a position opposite to the said top surface 14, a perimetral edge 18 acting as a contact surface 18' with the tiles 20.
  • the perimetral edge 18 is equipped with an external surface in which there are relief portions 19 and recessed portions 19'.
  • the cup body 12 of knob 10 is at least partially transparent.
  • the material in which the cup body 12 is made can preferably be chosen from transparent virgin polypropylene, polycarbonate, transparent polystyrene, polymethylmethacrylate (PMMA), polyethylene terephthalate (PET), polyvinyl chloride (PVC) or combinations thereof.
  • knob 10 is as follows: the base 30 of the threaded stem is placed on the floor (on the previously laid adhesive for tiles), then the tiles 20 (in the example four tiles) are positioned on their supporting surface, the edges 31 are aligned with each other so as to leave gaps F formed between the tiles 20. Then knob 10 is placed on the threaded stem (not represented for simplicity).
  • the body 12 of the knob 10 is transparent or at least partially transparent at least insofar as this transparency allows an operator to see or at least glimpse the edges 31 of the tiles 20 during installation facilitates advantageously its use.
  • knob 10 is simply let go and will self-tighten itself by means of thread 22 that will engage with the specially treated threaded stem, until it reaches the base of the threaded stem 30 positioning itself precisely on the tiles 20.
  • the knob 10 is pushed in a substantially vertical down along the stem thread without screwing, but using the slots 17 in the top surface 14 of the cup body 12 that open the flexible fins 15, widening the hole 16. (This operation and the one described above are considerably faster than the corresponding screwing operations of the known technique, thus bringing a considerable technical advantage).
  • the knob 10 thanks to said notches 17 basically self-screws on the threaded stem, the weight of the knob 10 is properly calibrated to screw on the stem in order to couple with the knob in this way, herein the knob ends its run on the surface of the tiles 20 remaining advantageously in place before the final tightening.
  • the knob 10 is placed with its own contact surface 18' of the perimetral edge 18 in contact with the face in view of the tiles 20 with the desired pressure, so as to make the latter planar. This is done for all the tiles to be laid.
  • knob 10 is removed and the threaded stem is separated from the base 30 using well-known points having facilitated breakage.
