Definitions

  • the present invention concerns a joining profile according to the preamble of claim
  • Such a joining profile is known from Fig. 2c of document WO 00/20705 A1 .
  • This joining profile is used for joining one particular type of tiles, namely floor elements.
  • this joining profile limits the laying freedom of the laying specialist. Indeed, once a first floor element has been joined to the joining profile, the second floor element can only by joined thereto by obliquely inserting the second floor element from above and then pivoting the second floor element downwards into its final position.
  • This angling method for laying the floor elements is not well suited for the installation of flooring under radiators or door frames. Also, the laying of specific patterns (for example the so called “fishbone”, “French fishbone” or mosaic patterns) with the floor elements is hard to do with this angling method.
  • a floor panel connector 1 12 is disclosed by document US 9,441 ,379. As shown in
  • floor panels 108 are connected by an angling method to the floor panel connector 1 12, which has the above-mentioned drawbacks.
  • this object is achieved with the joining profile according to claim 1 .
  • the locking lip By making the locking lip displaceable relative to the central supporting section, the locking lip can move out of the way when joining tiles.
  • the tiles can thus be joined by horizontal movement and not only with an angling motion.
  • the locking lip can completely move out of the way of a tile that approaches horizontally. Accordingly, tiles can be connected to the inventive joining profile by a pure horizontal translational movement.
  • the inventive joining profile has one, several or all the following features, in all technically possible combinations as defined in the dependent claims of the joining profile.
  • the invention also relates to a tiling assembly according to claim 1 1 .
  • the tiling assembly has the features of claim 12.
  • Figure 1 is a cross-sectional view of the joining area of two floor planks, which are joined to each other with the help of a joining profile according to the present invention
  • Figure 2 is an enlarged view of the circular area I I identified in Figure 1 ;
  • Figures 3 to 5 show the joining of two planks via the inventive joining profile using an angling method
  • Figures 6 to 15 show various examples of differently shaped tilings in which the inventive joining profile may be implemented.
  • Figures 16 and 17 are each cross-sectional views of the joining area of two floor planks, the joining area comprising joining profiles according to variants of the present invention.
  • the aim of the present invention is to provide a versatile connecting or joining system for interconnecting tiles such as floor elements of various shapes and sizes.
  • the inventive joining system should give the laying specialist a lot of freedom when laying and joining the tiles.
  • the inventive joining system should be quick and easy to install.
  • the industrial efficiency in manufacturing the joining profile shall be high.
  • the inventive joining system is in particular suited for interconnecting floor planks, floor tiles or similar floor elements to obtain a floor. It may also be used for interconnecting wall or ceiling tiles to obtain a wall or ceiling cladding. Another application is the assembly of furniture walls or parts thereof.
  • the tiles may have different geometries, such as rectangular, square, triangles or other polygons as well as rounded shapes like circles, ellipses and irregular and uneven shapes.
  • the tiles may be made of various materials, such as wood, metal, plastic or ceramics.
  • Fig. 1 there is shown, in cross-section, the joining area A of two interconnected tiles, namely parquet planks 2 and 4.
  • the two parquet planks 2 and 4 are shown in a laid state in which they rest on a subfloor 3.
  • the vertical direction V is defined as the direction perpendicular to the subfloor 3.
  • the horizontal direction H is defined as a direction parallel to the subfloor 3.
  • Fig. 1 only shows a fragment of each plank 2 and 4, namely the cross-section of one peripheral longitudinal side 5 of each plank.
  • the peripheral longitudinal sides 5 are used to interconnect the planks 2 and 4.
  • Each plank 2 and 4 has a top surface S.
  • This top surface is an aspect or wear surface, which means that it is visible when the plank lays on the subfloor 3.
  • the aspect surface S is the plank's surface which is walked upon in the laid state.
  • the two planks 2 and 4 are joined together at a longitudinal joint 7.
  • the joint 7 is defined by the contact zone of the two peripheral longitudinal sides 5.
  • Each parquet plank 2, 4 is a sandwich of three layers, namely a top aspect layer 6 followed by an intermediate core layer 8 followed by a bottom base layer 10.
  • the planks may of course have a different structure. They may be made of solid wood, have only two layers, etc.
  • planks 2 and 4 are identical (apart, possibly, from their overall shape and size), the following description equally applies to both planks.
  • the core layer 8 has a pair of longitudinal joining grooves 12, 14 for joining the plank to another plank.
  • One joining groove is a horizontal locking groove 12 for locking the plank in the horizontal direction H.
  • the other joining groove is a vertical locking groove 14 for locking the plank in the vertical direction V.
  • the horizontal locking groove 12 extends vertically into the core layer 8.

  • the vertical locking groove 14 opens out directly into the joint 7.
  • the horizontal locking groove 12 preferably has a u-shaped cross-section.
  • the vertical locking groove 14 preferably has a landing 16, as shown in Fig. 2.
  • the landing 16 is arranged between a first receiving channel 18 and a second receiving channel 20.
  • the cross-section of the second receiving channel 20 may be L-shaped.
  • the cross-section of the first receiving channel 18 may be U-shaped.
  • the first receiving channel 18 is set back further away from the joint 7 than the second receiving channel 20.
  • the plank 2, 4 also has a longitudinal recess 22 below the core layer 8 and next to the base layer 10.
  • the recess 22 has a ceiling 23.
  • the horizontal locking groove 12 opens out into the recess 22, preferably at the far side of the recess 22 from the joint 7.
  • the recess 22 has a cavity 24 in its ceiling 23.
  • the cavity 24 is formed into the core layer 8.
  • each plank 2, 4 Both longitudinal sides of each plank 2, 4 are identical. In other words, the opposite longitudinal side of each plank 2, 4, which is not shown in Fig. 1 , has the same grooves and recesses as the longitudinal side 5. More generally, all sides of a floor element preferably have exactly the same locking profile, no matter what the shape of the floor element is.
  • the two planks 2, 4 are joined together and locked in place by a joining profile 26.
  • This joining profile is preferably made of a polymer.
  • Polylactic acid (PLA) is a preferred polymer because it is recyclable and is sourced from renewable sources.
  • the joining profile 26 may be an integral piece. It may be obtained by an extrusion process or by means of injection moulding.
  • the joining profile 26 has an elongate shape, which defines a longitudinal main axis X.
  • the joining profile 26 includes a central supporting section 28, a central tongue 30 projecting from the central supporting section 28, and two peripheral tongues 32 each extending on opposite sides of the central supporting section 28 along the longitudinal main axis X.
  • Each peripheral tongue 32 has an upper tongue surface 35 for facing a tile and a lower tongue surface 36 for facing the subsurface 3.
  • the central supporting section 28 has a protruding base 34.
  • the base 34 protrudes below the lower tongue surfaces 36 of the peripheral tongues 32.
  • the base 34 has a lower base surface 37 facing the subfloor 3 and resting thereon.
  • the thickness T of the central supporting section 28 is larger than the thickness Q of the peripheral tongues 32. Accordingly, there is a clearance 38 between each peripheral tongue 32 and the subfloor 3, when the joining profile 26 rests on the subfloor 3.
  • the central tongue 30 has a rib 40 supporting a joining ridge 42.
  • the opposite lateral sides 44 of the joining ridge 42 jut out beyond the rib 40.
  • the cross- section of the joining ridge 42 may comprise a trapezoidal segment 46 followed by a rectangular segment 48.
  • Each peripheral tongue 32 ends with a locking lip 50.
  • Each locking lip 50 can move in the vertical direction V relative to the central supporting section 26 between a locking position shown in Fig. 1 and a release position before joining (not shown).
  • each peripheral tongue 32 is elastic such that it can bend downwards, whereby the corresponding locking lip 50 is moved from the locking position shown in Fig. 1 into the release position.
  • the locking lip 50 occupies the clearance 38.
  • the locking lip 50 leaves the clearance 38 open.
  • Each locking lip 50 may be hook-shaped. Each locking lip has a tip 51 . Each locking lip 50 also features a rounded outer guiding edge 53.
  • the thickening creates a bigger contact surface of the locking lip 50 with the floor element.
  • the relative pressure exerted by the locking lip 50 on the floor element 2, 4 is decreased, which reduces the compression of the floor element material at the contact point with the outer end of the locking lip 50.
  • the joining profile may also be used on the short end of a parquet flooring without the need for plywood or other additional materials like HDF, OSB or others.
  • the composition of the material of the joining profile 26 may vary throughout the profile.
  • the central supporting section 28 may be made of stiffer plastic than the peripheral tongues 32. This ensures a good structural integrity of the joining profile 26 due to the high tensile strength of the central supporting section 28, while keeping the flexibility of the peripheral tongues 32 needed for the locking operation.
  • the horizontal laying of the planks 2, 4 on the subfloor 3 and the joining thereof are done as follows.
  • the laying specialist starts with a pair of tiling assemblies 52.
  • Each tiling assembly 52 comprises one plank 2, 4 and a joining profile 26 connected to one longitudinal side of the plank 2, 4.
  • the other longitudinal side of the plank 2, 4 does not have a joining profile attached thereto.
  • Each joining profile 26 is connected to its plank 2, 4 in that a lateral side 44 of the joining ridge 42 is received in the vertical locking groove 14 of the plank 2, 4, and in that one of the two locking lips 50 is received in the horizontal locking groove 12 of the plank 2, 4.
  • the laying specialist then lays a first tiling assembly 52 onto the subfloor 3.
  • the second tiling assembly 52 is put onto the subfloor 3 next to the first tiling assembly, with the longitudinal side of the plank 4 lacking a joining profile facing the joining profile 26 of the first tiling assembly.
  • the longitudinal side 5 of the second tiling assembly is then moved horizontally towards the locking lip 50 of the joining profile 26 until it comes into contact with the locking lip 50.
  • the second tiling assembly is pushed horizontally over the locking lip 50. Thanks to the rounded guiding edge 53, the peripheral tongue 32 is pushed downwards by the horizontal approach of the second tiling assembly. This depresses the locking lip 50. Due to the fact that the lip height d is not larger than the recess height D, the locking lip 50 can move completely out of the way of the plank 4. Then, the second tiling assembly is moved further in the horizontal direction H towards the first tiling assembly until the locking lip 50 snaps upwards into the horizontal locking groove 12 and the other lateral side 44 of the joining ridge 42 is fully inserted in the vertical locking groove 14 of the second tiling assembly. As illustrated in Fig.
  • the trapezoidal segment 46 is received in the second receiving channels 20.
  • the rectangular segment 48 is received in the first receiving channels 18.
  • the locking lips 50 in cooperation with the horizontal locking grooves 12 prevent any horizontal relative movement of the two planks 2, 4.
  • the central tongue 30 in cooperation with the vertical locking grooves 14 prevents any vertical relative movement of the two planks 2, 4.
  • the central tongue 30 acts as a locking key, which locks the adjoining laid planks 2, 4 together in the vertical direction V, thus preventing any relative vertical movement between the two planks 2, 4.
  • inventive joining profile 26 allows for a joining of two tiles by horizontal displacement of the tiles only. No angling, tilting or lifting of the tiles is necessary during the joining process.
  • the central tongue 30 may extend up to and be flush with the aspect surface S of the planks 2, 4. In this way, one can create a floor with a ship deck optic. On top of that, the central tongue 30 may then act as a seal to prevent the ingress of liquid into the joint 7.
  • the laying specialist can insert a tool between the joining profile 26 and the planks 2, 4 to detach the joining profile from the planks.
  • Figs. 3 to 5 The oblique or angular laying of the planks 2, 4 on the subfloor 3 and the joining thereof are shown in Figs. 3 to 5.
  • Fig. 3 by the arrow, one first inserts the joining profile 26 into the first plank 4. The result is shown in Fig. 4.
  • the second plank 2 is approached at an angle to the joining profile 26 and snapped into place, cf. Fig. 5.
  • the angling movement corresponds to a vertical lowering movement and a concurrent horizontal approaching movement.
  • Figs. 6 to 15 provide examples of the multitude of tiling patterns that may be assembled with the inventive joining system.
  • the different patterns are as follows:
  • Fig. 6 mosaic pattern
  • Fig. 7 combined French fishbone and mosaic pattern
  • Fig. 8 fishbone pattern
  • Fig. 9 hexagon pattern
  • Fig. 10 cross pattern
  • Fig. 1 1 mosaic pattern
  • Fig. 12 ship deck optic
  • Fig. 13 concentric circles
  • Fig. 14 irregular shapes
  • Fig. 15 irregular curved planks.
  • two variants of joining profiles 26 are shown, together with planks 2 and 4.
  • each peripheral tongue 32 has a depression 54 extending along the longitudinal main axis X.
  • each peripheral tongue 32 has an undercut or oblique groove 56 extending along the longitudinal main axis X.
  • the depressions 54 and the undercuts 56 make the joining profile 26 more flexible during installation.
  • the inventive joining profile 26 and tiling assembly 52 have in particular the following advantages:
  • the tiles can be installed by horizontal displacement and not only with an angling process. This makes installation under radiators or doorframes much easier. It also simplifies the creation of all kinds of patterns with the tiles;
