Description
- The utility model relates to a system for leveling tiles and finds application in construction.
- Known from
WO/2018/136171 is an assembly and method for aligning and leveling tiles. That assembly includes a retainer and a tensioning key. The retainer consists of a base and a locking plate vertically connected to that base. At the point of connection between the base and the retainer plate there is a weakened section designed to tear-off and detach the plate from the base. On both sides of the locking plate is installed a guide, which is solid and has a cylindrical shape for inserting the tensioning key. The tensioning key has a head consisting of two identical arches located at a distance from each other forming a groove in which the retainer is place, and the two arches are connected to a single handle. The inner diameter of each arch corresponds to the outer diameter of the guide (6). On the outer surface of each arch, bevels are shaped to engage the tensioning key to the tiles. - The known system is too complex and impractical in real-world conditions and requires the installer to have special qualification. The outer surface of the arches is difficult to manufacture. If adhesive mixture enters between the base of the retainer and the lower part of the tile, there is a risk of premature rupture of the locking plate, as there will be no elastic buffer to offset these altered differences in surface heights.
- The mission of the utility model is to create a tile leveling system that has a simplified construction, is lightweight and reliable in operation.
- The mission is fulfilled by a tile leveling system that includes a retainer and a tension key. The retainer comprises a base and a locking plate mounted vertically to the base, and a weakened tear zone is formed at the place of connection of the base with the locking plate. A guide is mounted on both sides at the top of the locking plate, having a cylindrical shape for inserting the tensioning key. The tensioning key has a head made up of two identical arches spaced apart from each other, wherein a groove is formed in which the latch is placed, the two arches being connected to a common handle. The inner diameter (d) of each arch corresponds to the outer diameter of the guide.
- According to the utility model, stabilizing arms are formed at the bottom of the locking plate, on which ribs are longitudinally positioned. Transverse ribs are formed on the outer surfaces of the arches.
- On the outer surfaces of the arches there are sections protruding outwards. An opening is formed in the guide. The thickness of the retainer plate corresponds to the distance between the two arches and is functionally dependent on the width of the joint between tiles. The distance from the center of the guide opening to the base is functionally dependent on the thickness of the tiles.
- In another embodiment, a transition section is formed in the uppermost part of the locking plate wherein around the circumference of the retainer plate, on both sides of its vertical axes teeth are formed with inclination downwards to the base.
- The base and the locking plate of the retainer are made of plastic material.
- The utility model system has a simple and lightweight design. When working with it, smooth and precise pressure is exercised thanks to the longitudinal locking ribs of the locking plate, which engage the tiles. The teeth formed on both sides of the vertical axis allow the key to be inserted on one or the other side of the retainer, which is for the convenience of the worker. The teeth are tilted down to the base and serve to provide a stepped and gradual tension of the key when rotated around the guide by the worker, while preventing the key from turning in the opposite direction and preventing it from slipping.
- The guide of the locking plate allows for plasticity and deformation after the tensioning key is mounted on it. The driver prevents premature rupture in the weakened area and separation of the base and the fixing plate during installation. In addition, under heavy tension (when the tiles are pressed stronger against each other) the base is sufficiently elastic, so that the adhesive that is below the tiles and is stuck in the joints is automatically pushed to the inside of the tile without filling the joint with adhesive. The material of which the base is made allows it to deform and adhere tightly to two adjacent tiles, which have a thickness difference of 0.5 to 1 mm. Thanks to the ribs formed on the outer surface of the head of the tensioning key, a gradual and smooth tension is achieved, without any risk of tearing and detachment of the base and the fixing plate before the tiles are leveled.
- The utility model is explained in the drawings where:
-
Figure 1 is a general view of the tile leveling system -
Figure 2 is a general view of the tensioning key -
Figure 3 is a front view of the retainer -
Figure 4 is a side view of the retainer -
Figure 5 is a general view of the system, with the retainer with teeth -
Figure 6 is a front view of the retainer with teeth - As can be seen on the enclosed drawings, the tiles leveling system comprises a
retainer 1 and atensioning key 2. Theretainer 1 comprises abase 3 and a vertically mounted to thebase 3 locking plate 4. At the point of connection of the locking plate 4 to thebase 3, the locking plate 4 is of reduced thickness D wherein aweak tearing zone 5 is formed to allow for easy separation of thebase 3 from the locking plate 4. In the lower part of the locking plate 4 are formed stabilizing arms on which are longitudinally positioned theribs 15. On both sides in the upper part of the locking plate 4 is mounted aguide 6 of cylindrical shape for putting to the tensioningkey 2. A throughhole 10 is made in theguide 6. Thetensioning key 2 has ahead 8, consisting of twoidentical arches 17 placed at a distance from each other, wherein groove 21 is formed to hold theretainer 1, whereas the twoarches 17 are connected to acommon handle 7. The inner diameter (d) of eacharch 17 corresponds to the outer diameter of theguide 6 andtransverse ribs 13 are formed on eacharch 17 to engage the tensioningkey 2 to the tiles. On theouter surfaces 11 of thearches 17 are provided protrudingsections 12. The thickness C of the locking plate 4 corresponds to the distance between the twoarches 17 and is functionally dependent on the width of the joint between the tiles. - In another embodiment (
fig. 5 and fig. 6 ), along the circumference of the locking plate 4 there areteeth 19 formed on both sides of its vertical axis, separated by atransitional section 18 formed at the top of the locking plate 4. Theteeth 19 are inclined downward to thebase 3 and allow for inserting thekey 2 on one or the other side of theretainer 1, which is for the convenience of the worker. Theteeth 19 serve to exert a stepped and gradual tension on thekey 2 as it is rotated about theguide 6 by the worker, while preventing thekey 2 from rotating in the opposite direction and preventing it from sliding. - The distance F from the center of the
hole 10 of theguide 6 to thebase 3 is functionally dependent on the thickness of the tiles, whereby four variants are possible: - for tiles with thickness between 3 mm and 7 mm
- for tiles with thickness between 8 mm and 12 mm
- for tiles with thickness between 13 mm and 17 mm
- for tiles with thickness between 18 mm and 22 mm
- The base and locking plate are made of plastic material.
- When using the tiles leveling system, adhesive mixture is first applied on the surface where the tiles will be laid. The first tile is placed and a level is used to check that it is horizontal. Between the adhesive mixture and the bottom of the
tile 16 is inserted thebase 3 with the locking plate 4 perpendicular to the surface of the tiles, and the width of the joint is (between 1 and 4 mm) determined. After that, on the other side of the locking plate 4 is placed a second tile 16 (seefig. 1 andfig. 5 ) and then thetensioning key 2 is placed on theguide 6. Using thehandle 7 and thetensioning key 2, pressure is exercised in the direction of thetile 16 until the twoadjacent tiles 16 are levelled against each other. For the worker's convenience, theteeth 19 on both sides of the vertical axis allow the key 2 to be place on one or the other side of the retainer 4 (fig. 5 and fig. 6 ), whereas theteeth 19 inclined down to thebase 3 ensure stepped and gradual tensioning of the key 2 while the worker turns it around theguide 6 and in the same prevent the key 6 from returning in the opposite direction and from sliding. A significant role in exercising such pressure is played by thetransverse ribs 13 of thetensioning key 2, which in contact with thetile 16 achieves a double effect: precision tensioning and preventing theswitch 2 from returning to its original position. This action prevents the subsequent displacement of thetiles 16 relative to each other, both horizontally in the joint direction and vertically in the direction of the levels. This is repeated with allsubsequent tiles 16 laid. The configuration thus created between the key 2 and the locking plate 4 remains stationary for 7 to 24 hours, the time required for the initial adhesive mixture to harden. After the adhesive has hardened, the locking plate 4, together with thekey 2, is removed by means of a rubber hammer, leaving only thebase 3, which is detached from the locking plate 4, in thetear zone 5, under thetiles 16.
