Description

Title of the invention: “System for laying floor covering strips in a herringbone pattern” FIELD OF THE INVENTION

[0001] The present invention relates to a system for laying rectangular floor covering strips having pairs of long sides and

[0002] small sides each pair provided with a groove and a tongue, the large sides connecting to the other sides by tilting the tongue of the large side into the groove of another large side of a blade already installed, while this tilting movement of the blade to be installed in the blade already installed is done by clipping a small side of the blade to be installed into the small side of a blade already installed. STATE OF THE ART

[0003] Multiple forms of floor coverings are known with strips laid in a parallel pattern, by tilting the long sides around each other and clipping the short sides by the tilting movement of the strips along the long sides.

[0004] It is also known to lay floor covering strips in a herringbone pattern (or herringbone).

[0005] In the case of PVC or HDF slats, the long sides are provided with a tongue and a groove and the short sides are provided with connecting means compatible with the tongues and grooves and allowing a short side to be clipped into a long side.

[0006] But the broken stick installation is relatively delicate compared to the installation of parallel slats due to this pattern consisting of a broken line, formed by a succession of zig-zag slats, perpendicular to each other.

[0007] While this method of laying traditional parquet flooring slats is relatively simple, it is not so in the case of thin PVC or HDF flooring slats because of the necessary assembly method of such slats by tilting around the long sides and clipping the short sides into the short or long sides. This type of installation requires great precision in the installation to allow for the tilting and clipping movements.

[0008] This installation is even more complex to cover non-rectangular surfaces or those not having at least two perpendicular sides to start the installation from one side by aligning with the other perpendicular side.

[0009] Added to this is the risk of cutting errors because the orientation of the blades is not reversible; the mitre cut or more generally at an angle on a small side must be made on the correct end of the blade, respecting the position of the large side with the tongue and that of the large side with the groove.

[0010] PURPOSE OF THE INVENTION

[0011] The present invention aims to develop a system for laying PVC or HDM slats or more generally thin slats, having edges which are assembled by interlocking and tilting or clipping, facilitating the laying and avoiding the difficulties linked to possible laying inaccuracies accumulated by the succession of the assembly of the slats, according to the zig-zag pattern or broken stick pattern and the cutting errors of the slats which must be adapted.

[0012] DISCLOSURE AND ADVANTAGES OF THE INVENTION

[0013] To this end, the present invention relates to a system for laying rectangular floor covering strips, with pairs of long sides having one tongue profile and the other a groove profile of a shape complementary to that of the tongue profile and short sides, of a profile compatible with the profiles of the long sides, the strips being connected to each other by tilting and clipping the edge of the successive strips for their laying in a herringbone pattern,

[0014] installation system comprising:

[0015] - laying elements forming triangular laying templates for the laying line of broken stick blades,

[0016] - each laying element being formed of a triangle, isosceles rectangle composed of a filling of blades fitting into the triangle whose sides have a length equal to that of a blade, these blades being cut and assembled together to form the laying element

[0017] - one of the sides of the triangle being bordered by a part of the length of a large side at groove of one blade, completed by the small, compatible side of another blade and the other side of the triangle is bordered by a groove along its entire length.

[0018] The installation system according to the invention has multiple advantages because it allows precise installation of the blades according to the broken stick pattern, which is delicate to assemble, and it avoids cutting and positioning the blades to start the installation of the blades from the starting side of the installation.

[0019] The installation elements allow installation starting from a line orthogonal to the alignment line of the pattern but also installation along a line not perpendicular to the installation direction, a case which is frequent, in particular for the installation of covering strips on installation surfaces in old or renovated premises where the perpendicularity of the sides, i.e. the walls of the premises, is not necessarily extremely precise.

[0020] The invention thus allows rapid and efficient installation with great precision, avoiding alignment corrections which could be necessary in the case of installation from irregular or imprecise starting elements.

[0021] The laying elements, according to the invention, also have the advantage of adapting very simply to the different situations and in particular that of the non-orthogonality of the line of alignment of the laying corridors and that of the starting point of laying. In these conditions, it is sufficient to simply cut the laying elements with a miter saw, according to the angle of inclination of the starting side.

[0022] The blades of the laying elements or templates are preferably not only pre-cut in the factory but also assembled to form the template, thus combining the precision of the cutting of the blades and the precision of the assembly secured in the factory and constituting a laying element or template which is easily handled without risk of deformation or disassembly, even very reduced.

[0023] However, it may be necessary in certain cases to provide the template blades, pre-cut in the factory but not yet assembled. The blades will then all be referenced, for example, on the underside and their assembly will be clearly presented in an instruction manual.

[0024] Particularly advantageously for laying, the laying system comprises a layout with axes of the vertices and intermediate axes for positioning the blades applied in successive transverse lines in a broken stick pattern on the laying elements and the vertices of the blades representing the vertices of the succession of vertices of the stack copying the laying elements are on the axes of the laying corridors.

[0025] According to another advantageous characteristic, the blade laying system comprises a flexible, wound strip of locations, bearing, on a scale of 1 / 1, a layout by axes of the vertices and intermediate axes for the positioning of the blades applied in transverse lines in a broken stick pattern on the laying elements and of which the vertices of the blades representing the vertices of the succession of vertices of the stack copying the laying elements are on the axes of the laying corridors.

[0026] Particularly advantageously, to avoid having to fill small gaps which remain between the laid blades, for example on the alignment side, it is advantageous according to the invention to have blades of length increased by the blade width.

[0027] These blades of increased length are then, according to the invention, mitered to close the triangular voids which would remain beyond the small side of the blades of the corridor adjacent to the intermediate axis, overlapping the alignment side.

[0028] According to another advantageous characteristic, the system is applied to a non-rectangular laying surface whose starting side makes an angle of less than 90° with respect to the alignment side and consists of measuring the distance between the vertices of the laying elements of the layout whose base is aligned with the base side of the layout, perpendicular to the alignment side and the point of intersection of the height of the triangles with respect to the starting side to truncate these elements, according to the angle and distance to apply them, thus truncated, on the line of the vertices and their height aligned on the axis of the vertices passing through the vertex of the laying element.

[0042] DESCRIPTION OF EMBODIMENTS

[0043] According to [Fig.l] in its parts A, B, the invention relates to a system for laying rectangular floor covering strips having pairs of sides G, P, large sides G of which one has a groove RG, and the other side, a tongue LG; the small sides P are compatible with the tongue or groove of the large sides. The large side with tongue LG is highlighted in certain figures by a double line, the function of the other large side automatically following from it. The small sides having compatible profiles as will be described below do not require a particular reference to designate one or the other since they are compatible to be placed against a side with a RG groove or to receive the tongue of a side with an LG tongue.

[0044] The large sides G are connected to each other by the tilting of the blade whose tongue LG is engaged in the groove RG of a large side of a blade already installed; during this tilting movement of the blade to be installed in the one already installed, there is clipping of a small side of the blade to be installed in the small side of a blade already installed. This installation method is that of parallel blades.

[0045] In the case of installation according to the so-called "broken stick" pattern, the small sides P of the blades L are assembled to the large sides of the installed blades, which requires a shape XP of the small sides compatible with that of the large sides for the tilting and clipping movements.

[0046] The laying of the blades corresponds to laying corridors CP with the tops of the laying patterns and the hollows aligned respectively, according to the axes of the tops AS and the intermediate axes AL. These axes are parallel to a reference line which is, in general, the direction of the longest wall of the laying surface SP.

[0047] Thus, the laying corridors CP consist of a succession of pairs of blades L1, L2, perpendicular to each other and starting from an isosceles right triangle BTR constituted for a laying element or template 100 according to the invention; the base of this triangle is perpendicular to the axis of the vertices AS; it is applied against the starting side or wall if the laying direction is perpendicular to this starting side MD. The case of a starting side inclined relative to the laying direction will be examined next.

[0048] The accuracy of the blade placement depends largely on the accuracy of the placement of the first blades (all blades are identical) against the MD starting side.

[0049] To clearly highlight the BTR or RTB laying template (100) in Figures 1, 1A or even in Figures 2 and 3, the outline of the blades of the template (100) is not shown in the overall views so as not to confuse it with the blades which were laid from the templates 100 (Figures 1, 1A). But in reality and as already indicated, the template fits perfectly into the paving produced without being able to be distinguished from it.

[0050] According to the example shown separately, this triangular base BTR (template 100) is formed by the integral assembly of blades Ll / 0, L2 / 0, L3 / 0, cut with a miter at 45°, which is precision work, on which depends the position of the following blades Ll, ​​L2, in transverse progression to pass from one laying corridor CP to the next and to produce the transverse zig-zag line (at 45°) which is this broken stick pattern.

[0051] The sides of the triangle BTR are equal to the length of a blade L; they are formed either by the side RG of a blade L, or by the assembly of the small side P of a blade and the complement of the length of a large side RG of another blade so as to have a composite side of length equal to that of a large side.

[0052] The blades Ll / 0, L2 / 0 delimiting the sides of the triangle BTR (element 100), have a groove; the shape XP of the small side is compatible with the shapes RG and LG; it does not intervene in the inversion of the shapes RG / LG.

[0053] The blades that are being laid must fit into the blades of the row already laid; however, installation defects can accumulate and they risk being such that tilting or clipping becomes impossible. This then requires the tedious readjustment of the transverse rows of blades already laid.

[0054] The system of covering blades to be laid in a herringbone pattern, according to the invention, allows the precise positioning of the blades at the start of an installation for the SP installation surfaces which are perfectly rectangular but also for surfaces not having at least two perpendicular sides to start the layout of the installation. The template having at its base the width of an installation corridor (projection at 45° of the length of the blade) this allows a perfect installation of the blades then connected to the sides of the template which receive one, a blade over its entire length of composite sides and the other a blade over its entire long side and on the short side of the blade previously laid on the composite side aligned with the long side. We obtain sides perfectly aligned on the template to receive the installation of the following blades.

[0055] The system according to the invention consists of installation means integrated into the covering to be produced and therefore into the covering thus produced.

[0056] The system is composed in addition to the laying templates 100, forming laying elements 100 at the start of the laying corridors CP, of laying accessories making it possible to remedy the geometric irregularities of the laying surface SP (imposed surface which cannot be corrected) and also of elements facilitating the finishing and the completeness of the laid covering.

[0057] [Fig. 1 A] shows a herringbone laying pattern which can be considered as the inverse or plane-symmetrical of that of [Fig.l] but also as a laying pattern offset by one step (width of a herringbone laying line, measured along the direction of the AS axis).

[0058] To begin laying the blades of a CP corridor, the laying element 100 is a triangle RTB symmetrical to the triangle BTR.

[0059] [Fig.2] shows the start of the layout of the rectangular surface SP to be covered with rectangular blades L, according to the broken stick pattern.

[0060] The surface SP is delimited by two perpendicular sides, for example, a starting side or wall MD and an alignment side or wall MA. The laying corridors CP (axes of the vertices AS, intermediate axes AI) are aligned with the direction of the side MA.

[0061] The layout provides for delimiting the corridors CP by tracing the parallel axes AS, AI and the perpendicular transverse lines LS, crossing the axes AS to indicate the position of the vertices S of the blades L in the laying pattern and confirm the accuracy of the installation of successive blades.

[0062] By analogy with the vertex S of the laying element 100 (in its composition of RTB patterns of [Fig.lA]), the corners of the blades L which must be located on the axis AS are the corners of the blades L1, L2 bearing this same reference S.

[0063] Initially, on the MD side, templates formed by laying elements 100 composed of blades, cut and pre-assembled, are installed side by side. These elements are installed as they are according to the layout of the laying surface SP and they fit naturally into the laying surface.

[0064] The elements or templates 100 have a width exactly equal to the width of a CB laying corridor.

[0065] The laying element 100 is supplied, pre-assembled and composed of blades L, identical to those which will be laid and assembled from the succession of laying elements 100, installed by their base against the starting side MD.

[0066] A laying element 100 is shown next to the layout composed of more blades than that of figures 1, 1A but corresponding to the same concept of assembly of blades L1 / 0, L2 / 0, L3 / 0, L4 / 0, L5 / 0, nested; these blades are the same as those of the paving which will be carried out on the laying surface SP from the laying elements 100.

[0067] The templates 100 (100-1, 100-2, 100-3) are assumed to be in the RTB pattern ([Fig.lA]) i.e. having a composite left side formed by a fraction of the length of the RG groove and an XP compatible side and an entire right side formed by an RG groove over its entire length.

[0068] The blades placed against the sides of the templates 100-1, 100-2, 100-3 must respect the alternation of installation:

[0069] - a blade L2 on the left side of the template 100; it is engaged by tilting by its tongue in the composite groove and,

[0070] - the other blade Ll on the right side of the template; it is engaged by tilting by its tongue in the groove of the blade already installed on the small side of the blade L2 and the groove complement on the right side of the template 100.

[0071] This succession of blades L1, L2 continues on all the templates. We thus arrive at a first line of zigzag blades.

[0072] However, these blades cannot be placed one after the other because of the relief formed by the tongue on the large side LG of the blades Ll:

[0073] For each template 100, the blade L1 cannot be laid by engagement and tilting with its tongue on its LG side unless the blade L2 has already been laid on the other side of the template.

[0074] The RTB pattern of the template requires for a laying line that the L2 blades must be laid first on the side with full grooves and then the L1 blade covering the composite sides.

[0075] In the case of templates 100 with BTR pattern (symmetrical to the RTB pattern) the installation of a line of blades begins by installing all the L1 blades against the composite side of the templates then installing the L2 blades.

[0076] This procedure is repeated for the second line and so on.

[0077] The blades placed first in the first row are shaded in [Fig.3].

[0078] As previously, the sides of the triangle BTR are of length equal to that of a blade of which one of the sides has a groove RG and the other is a composite side composed of a small side and a part of a groove forming the complement.

[0079] The tracing of the axes AS, AI and the lines of the vertices LS is preferably done with a laser sight.

[0080] [Fig.3] shows the laying surface SP prepared according to [Fig.2], after the laying of a first transverse line of blades L1, L2... coming against the two respective sides of the laying elements 100, represented by an empty isosceles right triangle to facilitate presentation; the cut blades making up the laying elements 100 are identical to those which will be laid subsequently and they are integrated into the overall image of the paving without being able to be distinguished from it.

[0081] [Fig.3] shows the progression of the following line L4, which is still incomplete. The lines of blades thus successively form, each one a structure resembling a "broken stick" line, formed by the succession of blades L1, L2 in zig-zag, perpendicular.

[0082] [Fig.4] shows the case of a laying surface SP' delimited by the two sides MD1, MA which are not perpendicular. The laying layout requires the alignment of the laying corridors CP and the axes AS, AI, parallel to the side MA with which the starting side MD1 of the corridors CP makes an acute angle. If the angle between the sides MA, MD1 were obtuse, it would be sufficient to reverse the left / right layout and the order of the laying elements 100, described below in the case of [Fig.4A].

[0083] The layout drawn in [Fig.4] is made from the theoretical starting side MD0, perpendicular to the side MA. The survey of the laying surface SP gives the angle of the side MD1 relative to the side MA or MD0 (side of the layout perpendicular to the side MA). This makes it possible to draw the line MD1 which intersects the laying elements 100-1... 100-3 whose vertices S1-S3 are aligned with the line of vertices LSI.

[0084] Taking into account the intersection points PI, P2, P3 (Pn) of the heights (which are also the medians or bisectors) of the isosceles right triangles 100-1...100-3, the laying elements 100 can be cut with a miter saw according to the inclination of the cutting line and the distances from the points P1-P3 (Pn) to the vertices S1-S3 (Sn).

[0085] The elements 100-1... 100-3 thus prepared can be placed precisely on the laying surface SP with their vertices S1-S3, on the vertex line LSI and the sections of the height (mediatrix, etc.) of the elements 100-1... 100-3 oriented on the axes of the AS vertices of the CP1-3 laying corridors.

[0086] [Fig.4A] shows the elements 100-1... 100-3 placed on the surface SP' against the side represented by the line MD1.

[0087] [Fig.4B] shows the positioning without the lines and cut parts of the elements; the laying of the herringbone blade lines can then begin.

[0088] The blades L1, L2 of the broken stick line require cuts at different angles, this combined with a possible left side / right side inversion of the blades is a source of insurmountable difficulties and cutting errors, especially for the blades located here at the level of the intermediate axis AI2.

[0089] To reduce these risks in the case of a relatively significant inclination of the MD1 side with respect to the MD0 line, it is preferable to reduce the interval remaining between the sides of the elements 100-1... 100-3 for example at the level of the intermediate axis AI2 or AI3, by repositioning the element 100-3 which is the one which should be the most truncated, so that it is only slightly cut by the MD1 side, as shown in [Fig.5]. This consists of truncating the element 100-3 when its vertex S3 (Sn) is shifted by one notch to be on the line of vertices LS2 (LSn).

[0090] In this arrangement, the two upper blades of the element 100 are then part of the broken stick line which is limited to the blades L1, L2, L1 L2 covering the elements 100-1 and 100-2 ([Fig.5A]). This considerably limits the positioning inaccuracies and especially the risk of error in cutting the blades to adapt to the intervals between the laying elements 100.

[0091] [Fig.6] shows a strip-shaped installation accessory of locations 200 according to the invention, used both for the installation of the elements 100 and for their cutting for a straight starting side MD or inclined MD1.

[0092] This strip 200, for example made of paper, represents on a scale of 1 / 1, the layout of the laying elements 100, of the axes of the vertices AS and of the intermediate axes AI, the whole being bordered by the side MA and the starting side MD.

[0093] The length of this strip of locations 200 preferably corresponds to a laying width of the order of 4-5 m for laying corridors with a width of the order of 60-80 cm formed of blades with a length of the order of 50 cm.

[0094] To install this layout drawn at a scale of 1 / 1 on the strip 200, the strip 200 is unrolled, aligning its side B1 with the side MA.

[0095] In this particular example, because of the inclination of the MD1 side (MD1 wall), it is necessary to raise a part of the strip 200 by forming a dihedral edge MD1 and the two planes of which follow, one the laying surface SP and the other the wall (MD1).

[0096] This raised part can be cut along the edge of the dihedral (line MD1) and we will have the cutting lines to truncate the laying elements 100.

[0097] [Fig.7] shows in its part A another variant of the system according to the invention for relatively wide blades, laid in the direction of the MA side of the SP laying surface and whose other MD side is perpendicular.

[0098] For aesthetic or other reasons, the first CPI installation corridor is moved away from the MA side, leaving a strip going from the intermediate axis AI to the MA side, and which is covered by truncated blades L4.

[0099] In the layout variant of part B, the L1 blades would leave an empty triangle L0 or one that would have to be occupied with a complement having the shape L0 which would not fit well in the paving; to avoid this, the L1 blades will be replaced by L5 blades that are longer by a blade width and whose end is cut at 45°.

[0100] This cut can be made with a template provided to be used for cutting all the necessary long L5 blades or the truncated blades are part of the installation system and will be supplied truncated.

[0101] In case B of [Fig.7], while keeping the same orientation of the laying pattern and the succession of the blades L1, L2 forming the broken stick lines, the blades L5 are lengthened to cover the empty locations L0 and the elongated blades L5 are mitered.

[0102] The appearance of the broken stick pose is thus the appearance of the pose elements of [Fig.8] for the corresponding parts A and B.

[0103] As a remark, cases A and B of figures 7 and 8 can also be applied to the finishing of the laying of the last corridor of the laying surface which corresponds to case B if the laying surface SP has a width equal to an exact multiple of the width of a laying corridor or more generally to case A if the width of the laying surface SP is not equal to an integer multiple of the width of the corridor CP.

[0104] IN CONCLUSION: The system according to the invention is a laying system comprising

[0105] - laying elements (100) forming triangular laying templates for the line of laying blades (Ll, L2) in broken stick,

[0106] - each laying element (100) being formed of a triangle (BTR / RTB), rectangle isosceles composed of a filling of blades (L0) falling within the triangle whose sides have a length equal to that of a blade (L), these blades (L0) being cut and assembled together to form the laying element (100)

System for laying rectangular floor covering strips (L), with pairs of long sides having one a tongue profile and the other a groove profile of a shape complementary to that of the tongue profile and short sides of a profile compatible with the profiles of the long sides, the strips (L) being connected to each other by tilting and clipping the edge of the successive strips for their laying in a herringbone pattern, laying system comprising: - laying elements (100) forming triangular laying templates for the line of laying strips (L1, L2) in a herringbone pattern, - each laying element (100) being formed of a triangle (BTR / RTB), an isosceles rectangle composed of a filling of strips (LO) falling within the triangle whose sides have a length equal to that of a strip (L),these blades (LO) being cut and assembled together to form the laying element (100) - one of the sides of the triangle (BTR / RTB) being bordered by a length portion of a large grooved side (RG) of a blade, completed by the compatible small side (XP), of another blade and the other side of the triangle (BTR / RTB) is bordered by a groove (RG) over its entire length,

2. System for laying blades, according to claim 1, characterized in that it comprises a layout by axes of the vertices (AS) and intermediate axes (AI) for the positioning of the blades (L) applied in transverse lines in a broken stick pattern on the laying elements (100) and of which the vertices (S) of the blades (L) representing the vertices of the succession of vertices of the stack copying the laying elements (100, 100-1, 100-2, 100-3) are on the axes (AS) of laying corridors (CP).

3. Blade laying system, according to claim 2, characterized by a flexible, wound strip of locations (200), bearing on a scale of 1 / 1, the outline of the laying elements (100, 100-1...) juxtaposed along the length of the side (MD) of this strip and the axes (AS, AI), delimiting the laying corridors (CP) across the width of the strip as a start for the alignment of the laying corridors (CP) with respect to a reference direction (MA), regardless of the orthogonality defects of the starting side (DM, DM1) with respect to the alignment side (MA).

4. System for laying blades, according to claims 2 and 3, characterized by blades (P5) of length increased by the width of a blade (L) to be cut to the miter and close the triangular voids (LO) which remain beyond the small side (P) of the blades (L) of the corridor (CP), adjacent to the intermediate axis (AI) overlapping the alignment side (MA).

5. System for laying blades, according to claim 3, attached to claim 2 characterized in that for a laying surface (SP), non-rectangular whose starting side (MD1) makes an angle less than 90° with respect to the alignment side (MA), the distance between the vertices (S 1-3) of the laying elements (100) of the layout whose base is aligned with the base side (MDO) of the layout, perpendicular to the alignment side (MA) and the point of intersection (Pl-3) of the height of the triangles (BTR) (vertices Sn) with respect to the starting side (MD1) is measured to truncate the elements (100-1... 100-3), according to the angle and the distance (Sn-Pn) to apply them with their vertex (SN) on the vertex line (SL) and their height aligned with the vertex axis (AS) passing through the vertex (Sn) of the laying element (100-n).

6. Method for laying floor covering strips for herringbone laying, with a laying system according to any one of claims 1 to 5, characterized in that after the laying elements (100) have been placed on the starting side (DM, DM1), strips (L) are placed on the side of the laying elements (100), formed by the short side of a strip of the laying element, completed by the groove of a long side of the strip, forming the composite side and then the strips are placed on the other side of the laying elements (100), side extended by the short side of the strip just laid on each laying element and which extends the length of the groove complement in which the tongue of the strips to be laid is engaged.
