Definitions

  • the invention relates to a positioning system for covering elements, such as tiles or the like, for floors or walls.
  • a positioning system of the type defined in the preamble of claim 1 is disclosed in document WO 2013/023236 A .
  • the invention particularly relates to a positioning system for positioning covering elements which allows the mutual alignment of at least two adjacent covering elements, so as to obtain a flooring, or wall, with a regular visible surface, that is to say, without any steps, and with joints having a predetermined dimension.
  • the operator while positioning a covering element, must check that the covering element is coplanar with respect to the adjacent one(s), in order to avoid producing a flooring with an irregular extent or with steps between two adjacent covering elements.
  • the operator must further pay attention to the dimension of the joints, that is to say, the distance between two adjacent covering elements, so as to produce a flooring or wall with joints having dimensions which are almost constant.
  • the device described in EP2549030 comprises a spacer element which is provided with a base which is intended to support the bases of two adjacent tiles and a shaft which extends from the base in a direction perpendicular thereto and which is intended to be positioned between two adjacent tiles.
  • a threaded pin and a plate which is interposed between the base and the threaded pin is intended to be inserted during use between the facing edges of two adjacent tiles.
  • a weakened zone which is intended to act as a breaking line for the spacer element.
  • the alignment device further comprises a handle having a hollow body which is internally provided with a threaded hole which is intended to be screwed to the threaded pin and a flange which is intended to abut, during use, the visible surface of two adjacent tiles in order to level them.
  • the operator prepares and spreads the cement-based adhesive on the block, positions a tile on the adhesive, arranges the base of a spacer element on the adhesive under the tile, in such a manner that the plate is in abutment with a free edge of the tile. Subsequently, the operator positions a second tile on the adhesive in such a manner that a free edge thereof is in abutment with the free wall of the plate, so that the plate is interposed between the two adjacent tiles.
  • the operator screws the handle on the threaded pin, moving the flange into abutment against the visible surface of the two adjacent tiles and, by continuing to screw, subsequently generates traction on the spacer element, so as to progressively clamp the two adjacent tiles between the flange of the handle and the base of the spacer and to produce progressive alignment between the two tiles.
  • the device is fixed in position for sufficient time to bring about the setting of the adhesive, after which the operator unscrews the handle from the threaded pin, thereby separating it from the spacer element and, by pivoting the shaft of the spacer element with respect to the base thereof, brings about the breakage of the spacer element in the region of the intended breaking line, and therefore withdraws the shaft from the joint.
  • EP2573296 describes another levelling device which has the same disadvantages set out with reference to the device of EP2549030 .
  • An object of the invention is to provide a positioning system which allows the operations of positioning a flooring or wall to be made more rapid, yet ensuring at the same time that there is produced a flooring with a regular visible surface which has substantially no steps and with joints between the various adjacent covering elements having a predetermined extent.
  • Figure 1 shows a positioning system 100 according to the invention in a configuration for use in which it is used to position a first covering element 3 and a second covering element 4 which are mutually adjacent in order to produce a flooring or wall with a coplanar visible surface.
  • the positioning system 100 of the invention allows the positioning of two or more adjacent covering elements in such a manner that the respective visible surfaces are substantially coplanar and that there is produced a flooring or wall with a regular visible surface having joints of a predetermined width, as will be better described below.

  • the elements are levelled, that is to say, positioned so that the respective visible surfaces 3a, 4a are coplanar.
  • the positioning system 100 is maintained in that clamping position for sufficient time to bring about the setting of the adhesive 80, after which the operator can grip the fixing device 2 and, by acting on the actuation means 35, 45, open the seat 51.
  • the operator can, by keeping the seat 51 open, readily withdraw the fixing device 2 from the spacer element 1 so as to disconnect them.
  • the operator can break the spacer element 1 at the intended breaking line 10 and withdraw the shaft 8.
  • the positioning system of the invention allows an increase in the speed of the positioning operations, reducing the time necessary for connecting/disconnecting the fixing device 2 and spacer element 1.
  • the rest configuration W of the actuation elements corresponds to the closure of the seat 51, it is necessary for the operator to intervene to open the seat, and therefore the security of the system of the invention is increased, preventing accidental disconnection of the fixing device 2 and the spacer element 1.
  • the operation and the use of the fixing device 2' is substantially similar to that described above, in addition the guide elements allow guiding of the movement of the first and/or second fixing element 30', 40' during the movement from the rest configuration W to the operational configurations, and vice versa.
  • the presence of the guide elements 60' allows the operation of the fixing device 2' of the invention to be made more precise and the operation, that is to say, the opening/closure of the seat 51, to be kept precise over time.
  • the protrusions allow the fixing device 2' to be made dimensionally more stable with respect to the known devices.
  • the operation and the use of the fixing device 2" is substantially similar to that described above, in addition the guide elements allow guiding of the movement of the first and/or second fixing element 30', 40' during the movement from the rest configuration W to the operational configurations, and vice versa, and furthermore the reinforcement element 70 allows the operation of the device to be made more stable and the operation thereof to be improved.
  • the reinforcement element 70' can act as an additional travel stop element, abutting the upper wall of the plate 7, that is to say, the wall directed towards the threaded shaft.
  • the operator grips the fixing device 2'" and acts on the actuation tabs 90a, 91a so as to move the actuators 90, 91 in a radial direction towards the seat 51"'.
  • the thrust portions 90', 91' of the actuators are urged against the thrust end members 38, 48 of the fixing elements 30"', 40"'.
  • the thrust portions 90', 91' are radial, the spatial requirement of the actuators 90, 91 increases in the direction towards the inner wall 18.
  • the actuators 90, 91 being moved progressively, there is brought about a variation of the spatial requirement and a corresponding movement of the fixing elements 30"', 40'" in a radial direction.
  • the thrust portions 90', 91' apply a force against the thrust end members 38, 48 so as to urge the fixing elements 30"', 40'" away from the seat 51"', that is to say, so as to open the seat 51'" itself.
  • the presence of the guide elements and the reinforcement element also allows an improvement of the stability and the operation of the device.
