Description

[0001] The subject of the invention is a device for tiles levelling, in particular for adhesive-fixed cladding tiles, which allows the tiles to be positioned in one plane by levelling the neighbouring tiles.

[0002] Up to now, tile cross spacers have been used during laying ceramic tiles or other materials on walls, floors and other surfaces on which distance between contact surfaces of tiles is fixed. Tile cross spacers are provided with a pin of fixed diameter resting on four arms positioned in one plane which is perpendicular to the pin axis, whereby each spacer arm is located at an angle of 90° in relation to the next one. During tiles mounting tile cross spacers are positioned between contact surfaces of the tiles or in their corners, and the tiles are pressed to each other - in this way obtaining a fixed-width joint after the adhesive sets is ensured. Pins which protrude above the tiles surface are removed through mechanical destruction, and then this cavity is filled in with grout.

[0003] By using the previously known tile cross spacers, surfaces of high aesthetic qualities as regards joints appearance can be obtained; however, obtaining a level surface of the laid tiles is not ensured since the cross spacers cannot compensate for height differences between the neighbouring tiles.

[0004] A mounting and distancing element, owing to which a fixed width of the slit between the neighbouring tiles and positioning of top surfaces of all laid tiles in one plane can be obtained, is known from the Polish patent application P. 403536. The mounting and distancing element is in the form of a monolithic, spatial solid equipped with a base connected to a pin which is perpendicular to it, whereby on one edge of the pin base a cradle provided with a flat stand connected with two arc-convex surfaces is located, and on the other edge of the base a cradle provided preferably in its central part with a flat stand connected with two arc-convex surfaces is located, which cradles are inseparably attached to each other through a connector, whereby in the top part of the cradle a cuboidal base of the first pin with a rounded necking at the top is located, whereas on the other end of the base above the cradle the other cuboidal pin, which in its top part has a ridge whose bottom surface is inclined at an angle not greater than 20° and is tilted by not more than 20°, is located, whereas the base surface and the pin surface are located in one plane, like the surfaces opposite to them.

[0005] The purpose of the invention is to construct a device for cladding tiles levelling that allows the tiles to be positioned in one plane through levelling of two to four neighbouring tiles.

[0006] The device for tiles levelling according to the invention is characterised by that it has a body provided in its central part with a passage opening inside of which a core of the body provided with a positioning element is slidingly fitted, and a main knob whose flange is fixed inside the holder seat, whereby in the corners of the body there are threaded passage openings for spacer knobs arranged on a square plan, whereas the opening and the core in the cross-section transverse to their longitudinal axis are in the shape of a polygon or an irregular geometric figure of the contour in the shape of arcs, different from a circle. The core is provided with a blind hole for the guide bar of the positioning element. The positioning element is in the shape of a four-bar cross. The positioning element according to the variant is in the shape of a three-bar cross. The positioning element according to the variant is in the shape of a coaxial double-arm lever. The body of the device is preferably in the shape of a four-arm rosette. In the cross-section transversal to their longitudinal axis the passage opening and the core are preferably in the shape of a regular polygon. In the cross-section transversal to their longitudinal axis the passage opening and the core are preferably in the shape of an irregular polygon. In the cross-section transversal to their longitudinal axis the passage opening and the core are preferably in the shape of a geometric figure of the contour in the shape of arcs, different from a circle.

[0008] As it is presented in the drawing, the device for tiles levelling has a body 1, preferably in the shape of a four-arm rosette. In the central part of the body 1 there is a passage opening 2, preferably in the shape of a cuboid, for the cuboidal body 3 of the core 4 provided with a main knob 5. The main knob 5 is provided on the circumference with a flange 27, which is fixed inside the seat 28 located in the holder 29, which is inseparably attached to the body 1. In the branches 6, 6', 6", 6"' there are threaded passage openings 7, 7', 7", 7"' for spacer knobs 8, 8', 8", 8"'. The core 4 is provided with a blind hole 9 for the guide bar 10, whose one end is positioned inside the hole 9, and for its clamping inside the hole 9 the screw 11 screwed into opening 12 is responsible. The other end of the guide bar 10 is provided with a threaded end 13 and is used to mount on it the positioning element 14 through screwing it into the threaded opening 15. The positioning element 14 can be in the shape of a four-bar cross 16 or in the shape of a three-bar cross 17 or in the shape of a coaxial double-arm lever 18.

[0009] Operation of the device for tiles levelling consists in that tiles 19, 20 laid on an adhesive substrate are laid with the joint 21 retained or tiles 22, 23, 24, 25 are laid with the joint 21 retained. Then, before the adhesive sets, in case of tiles 19, 20 the end of the positioning element 14 in the form of a double-arm lever 18 is inserted into the joint 21 or in case of tiles 22, 23, 24, 25 the end of the positioning element 14 in the form of a four-bar cross 16 is inserted. Insertion of the positioning element 14 into the joint 21 is possible owing to the axial shift of the cuboidal body 3, whose axial movement along the passage opening 2 forces the turn of the knob 5. The knob 5 has a threaded opening 30 into which a threaded end of the core 4 is screwed. Then, when the body 1 is turned by an angle of approximately 45°, the arms 16 or 17 or 18 move under the tiles and in turn, through turning back the main knob 5, the core 4 moves, which results in the movement of the tiles towards the stands 26, 26', 26", 26"' of the spacer knobs 8, 8', 8", 8"', and thus their positioning in one plane is obtained. After the adhesive sets, the body 1 is turned by an angle of approximately 45° and it removes the arms 16 or 17 or 18 from the joint.
