    Abstract

    A flexible, preferably polymer-based, rectangular floor covering element of double-angling type has six sides: a decorative top face and a bottom face, as well as four edges. The first long edge has a first connection profile with a recess at the bottom face and a tongue overhanging the recess. The second long edge opposite the first long edge has a second connection profile with a protrusion at the bottom face and a groove for receiving the tongue of the first profile. The first short edge is equipped with the first profile and the second short edge is equipped with the second profile. When looking at the floor covering element from above the top face, the edges of the floor covering element are arranged in the following order in the clockwise direction: 1) the first long edge, 2) the first short edge, 3) the second long edge and 4) the second short edge.

    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

    [0026] FIG. 1 is a schematic top view of a part of a floor covering 10 made with flexible flooring tiles 12 in accordance with the first aspect of the invention. The flooring tiles 12 are of the double-angling type. Each flooring tile 12 has six sides: a decorative top face 14, a bottom face 16 (see FIG. 2) for contacting the underfloor 22 (see FIG. 2), two long edges 18a, 18b and two short edges 20a, 20b. The long edges comprise a first long edge 18a equipped with a first connection profile and a second long edge 18b opposite the first long edge 18a and equipped with a second connection profile that is complementary (conjugate) to the first connection profile. The short edges comprise a first short edge 20a equipped with the first connection profile and a second short edge equipped with the second connection profile.

    [0027] FIG. 2. Shows the first and second connection profiles in cross section. The first connection profile, hereinafter referred to as the male profile M, has a recess 24 at the bottom face 16 of the flooring tile and a tongue 26 overhanging the recess 24. The second connection profile, hereinafter referred to as the female profile F, has a protrusion 28 at the bottom face 16 of the flooring tile and a groove 30 for receiving the tongue 26 of the male profile M. The shapes of the connecting profiles are conjugate to each other meaning that they can be brought into engagement. It should be noted, however, that the contour lines of the male and female profiles in cross section need not be completely identical. In the illustrated example, the male and female profiles can be brought into interlocking engagement. When the tongue 26 of the male profile M is inserted into the groove 30 of the female profile F, a small temporary deformation one or both of the profiles is necessary for the tongue 26 to reach its final position in the groove 30. When the tongue has been completely inserted, there is no or almost no residual deformation. However, the abutments 32 and 34 on the tongue 26 and the protrusion 28, respectively, secure the tongue 26 against slipping out of the groove 30 without application of significant force or carrying out the reverse movement.

    [0028] When looking at the floor covering element from above the top face (as in FIG. 1), the order of the edges in the clockwise direction is: 1) the first long edge 18a (with the male profile—at the 12-o'clock position in FIG. 1), 2) the first short edge 20a (with the male profile—at the 3-o'clock position in FIG. 1), 3) the second long edge 18b (with the female profile—at the 6-o'clock position in FIGS. 1) and 4) the second short edge (with the female profile—at the 9-o'clock position in FIG. 1). The advantage of that arrangement of the connection profiles can be experienced when laying the floor covering. A floor is typically laid by first laying the rearmost row of flooring times from the left to the right and then installing the next row. Except for the first row and the leftmost tile in each row, a new flooring tile is always added in front and to the right of the tiles already in place.

    [0029] The male and female connectors shown in FIG. 2 are so-called angling-type connectors: when a new flooring tile is installed, the user holds it in the orientation described above and shown in FIG. 1. The user then angles the edge on the left of the new flooring tile under the overhanging tongue of the flooring tile on the left already in place (see FIG. 3). When the tongue has thereby entered the groove, the new flooring tile is hinged down. During this movement, the connection profiles deform resiliently and then snap into place. Depending on the stiffness of the polymer material of the flooring tile (and thus the connection profiles) a clicking noise may or may not be heard by the user. The male and female profiles are now interlocked with each other such that their separation would require a high amount of force (potentially leading to damage on the flooring tiles) or the reverse movement of the profiles. The next step is the connection of the new flooring tile with the tile or the tiles in the row behind. The user typically holds the new flooring tile with both hands. The left hand supports the new tile at the corner of the second long edge 18b and the second short edge 20b while the right hand supports it at the corner of the second long edge 18b and the first short edge 20a. The new tile and the tile to its left are already connected with each other. The user now raises the second long edge 18b of the new tile, giving the new tile a decline towards the row behind. The tile to the left has to follow that decline because of its engagement with the new tile. At this point, a conventional flexible double-angling flooring tile would be likely to disengage from the row behind and the user would have to be quite careful to avoid that. With flooring tiles according to the first aspect of the invention, the risk of the already installed tiles to the left disengaging from the row behind is significantly reduced. Keeping the tile to be installed inclined, the user pushes it with the male profile of the first long edge 18a into the female profile of the second long edge of the tile(s) behind it. When the connection profiles are in contact, the user lowers the second long edge 18b of the new tile on the underfloor. By that rotational motion of the new tile, the male and female profiles become interconnected along the long edge.

    [0030] FIG. 4 shows an example of a packaging 36a of a set of flooring tiles according to the first aspect of the invention. The packaging 36a comprises several indications that the flooring tiles are most suitable for installation by right-handed persons, in particular a matrix barcode 38a, a pictogram representing a right hand 40a and a textual notice 42a.

    [0031] FIG. 5 shows an example of a packaging 36b of a set of flooring tiles according to the fourth aspect of the invention. The packaging 36b comprises several indications that the flooring tiles are most suitable for installation by left-handed persons, in particular a matrix barcode 38b, a pictogram representing a left hand 40b and a textual notice 42b. It will be appreciated that flooring tiles of a set according to the fourth aspect of the invention are mirrored versions of flooring tiles according to the first aspect of the invention. In fact, either the short or the long edges of the tiles are permuted. Installation of the mirrored tiles is carried out in exactly the same way as that of the tiles of FIG. 1, except that left and right are inverted.

    [0032] It will be understood that flooring tiles according to the first aspect of the invention are most suitable for installation from left to right, while mirrored flooring tiles are most suitable for installation from right to left, irrespectively of the handedness of the person installing them.

    [0033] While specific embodiments have been described herein in detail, those skilled in the art will appreciate that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the invention, which is to be given the full breadth of the appended claims and any and all equivalents thereof.
