  MULTIFUNCTION FINISHING ASSEMBLY FOR COATING

  SOL, MANUFACTURING METHOD AND INSTALLATION METHOD

DUDIT TOGETHER

  TECHNICAL FIELD The present invention relates to a multifunction finish assembly for flooring, which can be used in at least two different applications, and preferably as a connecting bar between two floor coverings or threshold bar, or as a connecting bar between two floor coverings or stop bars, either as a connecting bar between two floor coverings or threshold bar or stop bar.

  PRIOR ART In the field of the laying or renovation of floor coverings, or the renovation of floors, it is common practice to use finishing elements in the form of finishing bars, for example made of wood, metal or plastic. , which are intended to be fixed to the ground, so as to cover the edge of at least one floor covering. Among these finishing elements we find mainly the connecting bars, the threshold bars, the stop bars and the nosings. The application for which the finishing bar is intended (crossbar, threshold bar, stop bar or stair nosing) is determined by its cross-sectional profile.

  Finishing elements for floor covering such as a terminal bar, threshold bar, stop bar or stair nosing are described for example in US patent applications and patents US2003 / 0154678, US2004 / 0206038, US 6,745,534. , US 6,805,951, US 6,517,935, in the French patent applications FR 2 737 237, FR 2 848 234, FR 2 695 671, FR 2 783 854, and in the patent application is designated in this text by a bar 2881157 2 bar designed to be placed on the ground at the interface between two adjacent flooring (carpet, parquet, tiles, ...). This type of bar generally has a T-shaped cross-sectional profile. Each wing of the T is used to cover the edge of one of the two coverings, and the T-foot is used to fix the bar to the ground, for example cooperating with a fixing rail or equivalent permanently fixed between the two coatings. The junction bar thus makes it possible to mask the joint between the two floor coverings and to confer a better aesthetic on the transition between the two floor coverings. In addition, the junction bar makes it possible, if necessary, to make up and hide slight differences in thickness between the two floor coverings.

  In the present text, the term "threshold bar" designates a bar that is generally used to ensure the transition between a floor covering (carpet, parquet, tile, etc.) and the floor or between two floor coverings having an offset in high height. It thus has the function of catching and masking differences in height between a floor covering and the floor or between two floor coverings.

  In the present text, the term "stop bar" designates a bar ending generally opposite the floor covering by a substantially vertical face. This type of bar is generally used as a finishing element between a floor covering and a vertical wall such as a wall or partition.

  Steps are bars that have an L-shaped cross-sectional profile and are intended to be mounted at the angle of a step.

  To improve the aesthetics and / or the wear resistance of the finishing bars for flooring, it is also known to apply on these bars, during their manufacture, a surface coating which is for example a film or sheet of material stuck on the upper surface of the bar. For example, the aforementioned US patents US 6,805,951 and US 6,517,935 disclose a method of manufacturing a finish member 2881157 3 having a thin and abrasion resistant coating which is of multilayer type.

  With the goal of simplifying inventory management and offering customers a unique multipurpose product, in the last few years, finishing bar manufacturers have been turning towards the manufacture and marketing of multipurpose and ready-made finishing bar sets. -to rise. A multifunction finishing assembly is described for example in the international patent application WO 03/040492. In this publication, the multifunction finishing assembly includes a T-shaped terminal bar on which an additional side bar is fitted. When the additional sidebar is assembled with the T-element, the assembly can be used as a threshold bar (proud application). To use the assembly as a joining bar (2nd application), it is sufficient to separate the additional bar from the T-shaped bar, the latter being able to be used as a connecting bar.

  A disadvantage of multifunction finishing assemblies known to date lies in the presence of a longitudinal gap at the junction of the surfaces of the individual bars composing the assembly. This interstice not only impairs the aesthetic quality of the finishing assembly, but also adversely affects a zone of weakness that can be easily damaged over time, and which can also become clogged more easily.

detailed description

  FIG. 1 shows a finishing assembly for flooring, which is in accordance with a first preferred embodiment of the invention, and which can be used in three different applications as a crossbar, threshold bar or bar stop.

  This finishing assembly consists of five elements: three finishing bars, of the same length, and for example of wood, namely: a central bar 1, and two lateral bars 2 and 3 disposed on either side of the bar plant; a surface coating 4 applied to the three finishing bars 1, 2 and 3, a base 5, for example plastic.

  The two side bars 2 and 3 have different profiles in cross section (that is to say in a plane perpendicular to their longitudinal axis).

  When used alone, the finishing bar 1 constitutes a connecting bar (1st application). The two bars 1 and 2, when used together, form a threshold bar (2nd application). The two bars 1 and 3, when used together, form a stop bar (3rd application).

  More particularly, in the example shown, the connecting bar 1 is symmetrical about a median longitudinal plane (P), and has a T-shaped cross-section with a central foot 1a, and two lateral wings 1b and 1c. identical and symmetrical to each other with respect to the plane P. The bar 1 has an upper surface 1d which is flat in its central part and which has an arcuate curvature at the ends of the two wings lb and 1c .

  The side bar 2 is a separate part of the aforesaid bar 1 and is positioned side by side with the bar 1 between the central foot 1a and wing 1b. The bar 2 comprises an upper face 2a, which partly comes into contact with the lower face of the wing 1b, a lower face 2b, an inner lateral face 2c oriented towards the central foot 1a of the bar 1, and a lateral face external 2d slightly curved. The external lateral face 2d of the bar 2 is in the extension of the upper face 1d of the central bar 1, a longitudinal gap 6 separating the two faces 1d and 2d along the entire length of the bars 1 and 2.

  The bar 3 is a separate part of the aforesaid bar 1 and is positioned side by side with the bar 1 between the central foot 1c and the wing 1c. The bar 3 has an upper face 3a, which comes partly in contact with the lower face of the wing 1b, a lower face 3b, an inner lateral face 2c oriented towards the central foot 1a of the bar 1, and a face lateral external 3d which is substantially flat and oriented perpendicularly to the flat central portion of the upper face 1 d of the bar 1. The external lateral face 3d of the bar 2 is in the extension of the upper face 1d of the central bar 1 , a longitudinal gap 6 'separating the two faces 1d and 3d over the entire length of the bars 1 and 3.

  The surface coating 4 is a flexible sheet of (monolayer or multilayer) material of rectangular shape, which is applied, being fixed by any known means and for example by gluing by means of an adhesive, on the upper face 1d of the bar 1 and the external lateral faces 2d and 3d respectively of the bars 2 and 3. The surface coating 4 covers all of the aforementioned surfaces 1d, 2d and 3d, and especially covers and advantageously masks the two longitudinal gaps 6 2881157 11 and 6 '. The three bars 1, 2 and 3 are thus integral with each other via this surface coating 4.

  More generally, in the context of the invention, the surface coating of the finishing assembly can be constituted by any thin coating that can match the curved surface of the individual bars of the finishing assembly, whatever the nature the material or materials constituting the coating and whatever technique is used to apply the coating on the bars of the finishing assembly. In particular, the coating may be of the monolayer type or of the multilayer type. It may for example comprise a film or a sheet of plastic, paper, wood, or be made of any known textile (non-woven, woven fabric, ...). Preferably, but not necessarily, the coating will be decorative and / or have improved mechanical properties against wear. Preferably, but not necessarily, the surface coating is glued (cold or heat sealed) to the bars of the finish assembly.

  The base 5 is a profile, preferably plastic, of the same length as the bars 1, 2 and 3. It comprises a base plate 5a and two longitudinal walls 5b identical, parallel and substantially perpendicular to the base plate 5a. These two walls 5b form with the base plate 5a, a 5 'U-shaped rail for fixing the floor or bars of the finishing assembly.

  In the particular embodiment of Figure 1, the base 5 further comprises two lateral flanges 5c which extend the base plate 5a on either side of the U-shaped fastening rail 5 '. Each lateral flange 5c is breakable relative to the 5 'channel U. Preferably, in order to facilitate the separation by cutting of each lateral flange 5c, a longitudinal groove 5d V is formed at each junction between the U-shaped fastening rail 5' and each lateral flange 5c, said V-shaped groove 5d constituting a separation line of smaller thickness.

  More particularly, the two lateral bars 2 and 3 comprise respectively in their lower faces 2b, 3b two longitudinal grooves 2e and 3e. Each lateral flange 5c of the base 5 terminates in a longitudinal retention peg 5e which is designed to fit, preferably with interference, into one of the grooves 2e or 3e.

  More particularly, each wing 5c of the base 5 has an additional longitudinal lug 5f which is breakable. With reference to FIG. 1, the additional lugs 5f are accommodated in the two aforementioned longitudinal grooves 2e and 3e, so that the base 5 is temporarily assembled with the two lateral bars 2 and 3. Preferably, the two lugs 5f are slightly elastically flexible relative to the base plate 5a, so that the base 5 is secured by pinching the bars 1, 2 and 3 between the two provisional lugs 5f.

  In the embodiment of FIG. 1, the base 5 advantageously makes it possible to lock the lateral bars 2 and 3 in position against the bar 1, and in particular to prevent the lateral bars 2 and 3 from moving to the central bar 1 in a plane parallel to the cross section of the bars. The assembly 1, 2, 3, 4 and 5 thus constitutes a ready-to-use and multifunctional finishing assembly, which can advantageously be easily handled and / or transported and / or presented for sale. For its presentation for sale, this set can of course be packed with a user manual, in a transparent plastic packaging.

  More particularly, in the variant of Figure 1, the lower face of each wing 1b and 1c of the central bar 1 comprises a longitudinal locking groove 1f forming a double stop, in which is positioned a longitudinal portion 2f projecting or 3f of the bar 2 or 3. Said projecting portion 2f or 3f makes it possible to block laterally in translation the lateral bar 2 or 3 with respect to the central bar 1 along an axis D perpendicular to the median longitudinal plane P of the bar 1.

  Preferably, the lateral faces 1g of the central foot 1a of the bar 1 comprise a longitudinal groove 1h forming a double stop, in which 2881157 13 is housed a longitudinal portion projecting 2h (respectively 3h) of the bar 2 (respectively bar 3 ), which allows locking in translation of the bar 2 (respectively bar 3) relative to the foot 1a of the bar 1 in a plane parallel to its cross section and along an axis F perpendicular to the aforementioned axis D. Preferably the thickness (e) of the protruding longitudinal portion 2h (respectively 3h) of the bar 2 (respectively bar 3) is less than the height (h) of the groove 1h so that there is between the bar 2 (respectively bar 3) and the bar 1, a slight clearance which advantageously allows a slight displacement of the bar 2 (bar 3 respectively) relative to the bar 1 in a plane parallel to the cross section of the bars. The usefulness of this deflection will appear more clearly later in the light of figure 26.

  Advantageously, the longitudinal portions in the groove 2h and 3h make it possible to arrange on either side of the foot 1a of the central bar 1, a longitudinal space E, which is able to serve as a housing for the walls 5b of the fixing rail 5 'of the base.5.

  According to a further preferred characteristic, the lateral bar 2 (respectively lateral bar 3) comprises a longitudinal recess 2i (respectively 3i) which extends over the entire length of the bar and which is opposite the underside of the bar. wing 1b (respectively wing 1 c) of the bar 1. This recess 2i (respectively 3i) delimits with the lower face of the wing 1b (respectively wing 1c) of the bar 1 a throat G of small width (I) allowing insertion and guidance of a cutting blade. The entrance of this groove G corresponds to the gap 6 or 6 '. In practice, the width (I) of the groove will preferably be greater than 0.6 mm.

  Figures 2 to 7 illustrate the main successive steps of manufacturing the finishing assembly of Figure 1.

  Step 1 (Figures 2 and 3) The tie rod 1 is manufactured and an intermediate piece 1 constituted of the two bars 2 and 3 connected over their entire length by a provisional longitudinal bridge P breakable. Depending on the type of material these parts 1 and I are manufactured for example by machining (wooden parts) or by extrusion (plastic or metal parts).

  Step 2 (Figure 4) We assemble, by simple interlocking, the bar 1 with the intermediate piece I, the foot of the bar 1 being housed in the longitudinal space defined by the two outer lateral faces vis-à-vis 2c and 3c bars 2 and 3 and the temporary bridge P. During this assembly, the protruding portions 2f and 3f of the bars 2 and 3 are housed in the corresponding grooves 1f of the bar 1, which allows a centering of the assembly barre2 / barre3 / temporary bridge P relative to the bar 1. As a result, the bars 2 and 3 are perfectly positioned and maintained in position relative to the bar 1 during the subsequent operation of application of the surface coating 4 (Step 3 / Figure 5).

  Step 3 (FIG. 5) The surface coating 4 is applied to and bonded to the assembly formed by the parts 1 and 1 so as to completely cover the faces Id, 2d and 3d of the bars 1, 2 and 3. The technique application and gluing of this coating is known per se and therefore will not be detailed in the present application. The temporary bridge P advantageously makes it possible to hold the bars 2 and 3 with respect to the bar 1 during the application operation of the surface coating 4.

  Once applied, the surface coating 4 advantageously masks the two interstices 6 and 6 '.

  Step 4 (FIGS. 5 and 6) The provisional bridge P connecting the bars 2 and 3 is removed by cutting it with a cutting tool [for example a cutting blade (FIG. 5) or a saw), so that the bars 2 and 3 are not directly integral with each other (Figure 6). The bars 1, 2 and 3 are held together by the surface coating 4.

  Step 5 (FIGS. 7 and 1) The base 5 which has been previously manufactured (FIG. 7) is assembled, for example by extrusion, with the assembly of bar 1 / bar 2 / bar 3 / coating 4 previously constituted, so as to form the finishing assembly of Figure 1. This assembly operation is carried out simply by fitting the side bars 2 and 3 on the breakable provisional pins 5f of the base 5. In this configuration of Figure 1, the base 5 advantageously allows to replace the aforementioned temporary bridge P, mechanically connecting the two bars 2 and 3 together, and keeping them applied against the central bar 1. The finishing assembly of Figure 1 can thus be handled without the risk of moving the bar 2 or the bar 3 relative to the bar 1, and therefore without the risk of damaging the coating 4.

  The different possibilities of use of the finishing assembly of FIG. 1 will now be detailed with reference to FIGS. 8 to 10 Use as a tie-rod (FIG. 8). FIG. 8 shows the implementation of FIG. the central bar 1 of the assembly of Figure 1 as a connecting bar, interposed between two floor coverings RI and R2 having substantially the same height H relative to the ground. It can be any known type of flooring (parquet, carpet, tiles, linoleum, ...). To achieve the implementation of Figure 8, it is sufficient for the end user holding the finishing assembly of Figure 1 to carry out the operations below.

  The base 5 is detached from the bars 2 and 3 of the finishing assembly. The base 5 is cut along the two V-shaped grooves 5d so as to keep only the U-shaped fastening rail 5 '. The coating 4 is cut with a blade or equivalent along each longitudinal groove. G, so as to separate the lateral bars 2 and 3 (and their surface coating portion 4) from the central bar 1 and its surface coating portion 4. The width (I) of each gap 6, 6 ' being sufficient to slide a cutting blade into the groove G, a clean cut of the coating 4 is advantageously obtained.

  Next, the base 5a of the fastening rail 5'in U between the two coatings R1 and R2 is fixed on the ground by any appropriate means chosen in particular according to the nature of the ground (for example screwing and / or bonding). . The central foot 1a of the bar 1 is inserted between the two arms 5b of the rail 5 'and pushing it in until the two wings 1b and 1 of the bar come into contact with the surface of the two coatings R1 , R2. Preferably, the inner face of the two arms 5b is crenellated so as to allow blocking in position at different heights of the connecting bar 1, depending on the height H of the coatings.

  Use as a threshold bar (FIG. 9) FIG. 9 shows the implementation of the finishing assembly of FIG. 1 as a threshold bar between a floor covering R and the ground underlying this covering. of soil. To achieve the implementation of Figure 9, it is sufficient for the end user holding the finishing assembly of Figure 1 to carry out the operations below.

  The base 5 is detached from the bars 2 and 3 of the finishing assembly. The base 5 is cut manually along one of the V-shaped grooves 5d so as to keep only the U-shaped attachment rail 5 'and a lateral wing 5c, the other lateral wing 5c being removed. The temporary lug 5f of the remaining wing 5c is cut out.

  The coating 4 is manually cut by means of a blade or equivalent, slid into the groove G so as to separate the lateral bar 3 (and its surface coating portion 4) from the remaining assembly: bar 1 / bar 2 / coating 4 covering bars 1 and 2.

  Then, the base 5a of the U-shaped fastening rail is fixed on the ground along the edge of the coating R by any appropriate means selected in particular according to the nature of the ground (for example screwing and / or bonding).

  The foot 1a of the central bar 1 is inserted between the 5 'U-shaped rail and the longitudinal holding lug 5e in the lower groove 2e of the bar 2.

  The bar 1 / bar 2 / coating 4 assembly is depressed until the wing 1c of the bar 1 comes into contact with the surface of the coating R. 2881157 17 Use as a stop bar (FIG. shown in Figure 10, the implementation of the finishing assembly of Figure 1 as a stop bar between a floor covering R and the ground underlying this floor covering. To achieve the implementation of Figure 9, it is sufficient for the end user holding the finishing assembly of Figure 1 to perform the same operations as those described above for the threshold bar application, but replacing in the explanations bar 2 by bar 3.

  Referring to Figure 9 (threshold bar) and Figure 10 (stop bar), it is understood that the coating 4 covering the interstitial seal respectively 6 and 6 ', it advantageously protects it against any fouling and hide it, which improves the aesthetics of the finish. Also, it avoids the risk of delamination or deterioration of the surface coating 4 at the junction between the two bars 1 and 2, or between the bars 1 and 3.

  FIG. 11 shows another alternative embodiment of a finishing assembly of the invention, which is different from the finishing assembly of FIG. 1, by the absence of pedestal 5, and by the presence a provisional bridge P interconnecting the two lateral bars 2 and 3. At the junction between the bridge and respectively the two bars 2 and 3 are formed longitudinal grooves V 2g and 3g. The bridge P is intended to be used to fix the floor, for example by gluing or screwing, the bar 2 or the bar 3 according to the chosen application (threshold bar or stop bar), after the other bar no used in the application has been separated from the bridge P. There is shown in Figure 12, a third embodiment of a finishing assembly of the invention. In this variant, the lateral faces 1g of the central leg 1a of the T-shaped central bar 1 are crenellated so as to allow a height adjustment of the foot 1a in the U-shaped fixing rail 5 '. FIGS. 15 show the finishing assembly of FIG. 12 used respectively as a tie bar, threshold bar and stop bar.

  FIG. 16 shows a fourth variant embodiment of a finishing assembly of the invention. In this variant, the bars 2 and 3 and the U-shaped fastening rail 5 'form an integral part of the same one-piece assembly 7. This one-piece assembly 7 is preferably an extruded plastic profile.

  Figures 17, 18 and 19 show the finishing assembly of Figure 16 used respectively as a tie bar, threshold bar and stop bar. Note that for Figures 18 and 19, the bars 2 and 3 have been previously separated by cutting the U-rail 5 '.

  FIG. 20 shows a fifth variant embodiment of a finishing assembly of the invention, which is intended to be used with the two U-shaped fastening rails 8 and 9 of FIG. a U-shaped section whose side walls 8b are crenellated on their inner faces. The rail 9 is a U-shaped profile whose side walls 9b are crenellated on their outer and inner faces. The rail 9 is also nestable in the rail 8, and is adjustable in height relative to the rail 8 through the cooperation of its external crenellations 9c with the internal crenellations 8c of the rail 8.

  FIG. 26 shows the finishing assembly of FIG. 20 configured as a stop bar, and used for a transition between a floor covering R and the ground, said finishing assembly being fixed to the ground by means of the two rails 8 and 9 nested. In the application illustrated in this figure, the two rails 8 and 9 are offset with respect to each other, the base 9a of the rail 9 not being parallel to the base 8a of the rail 8 but forming with said base 8a an angle A, so as to allow a level of catch-up between the ground and the coating R. This inclination of the rail 9 relative to the rail 8 is obtained by slightly deforming the lateral branches 8b of the U-shaped rail 8 with respect to its base 8a. Furthermore, it will be noted that in this embodiment (as well as in the variant embodiments of FIG. 1 and FIG. 16), this inclination is made possible thanks to the clearance existing between the groove 1h and the projecting portion 3h of the bar 3 (dimension (e) slightly less than the height (h) of the groove 1h), which clearance allows movement of the bar 3 relative to the bar 1 in a plane parallel to the cross section of the bars.

  FIG. 27 shows a sixth variant embodiment of a finishing assembly of the invention, which is intended to be used with the two fastening rails 10 and 11 of FIG. 28.

  The rail 11 is constituted by a U-shaped section. The rail 10 is constituted by a T-section and is nestable at different heights in the U-shaped section. In the finishing assembly of FIG. of the bar 1 T-shaped comprises a longitudinal groove 1 i to fit this bar on the foot 10b of the rail 10 in the form of T. The two side bars 2 and 3 are interconnected by a temporary bridge P breakable, which is intended to be cut out during the floor installation of the entire 2881157 20 finish.

In this application, the finishing assembly is fixed to the ground by means of the two rails 10 and 11 nested one inside the other, the groove li of the central bar 1 T being fitted on the fixing rail 10 in form T, and the rail 11 being fixed by any means (gluing, screwing, ..) to the ground.

  FIG. 30 shows the finishing assembly of FIG. 27 configured as a threshold bar, and used for a transition between a floor covering R and the ground, said finishing assembly being fixed to the ground by means of the two rails 10 and 11. nested. In this application, the bars 1 and 2 are spaced apart from each other in a plane parallel to their cross-sections, the base 10a of the T-rail 10 being inclined with respect to the base 11a of the U-shaped rail 11. similar to the application of FIG. 26, this inclination is made possible thanks to the clearance existing between the groove 1h and the projecting portion 2h of the bar 2, which clearance allows a displacement of the bar 2 with respect to the bar 1 in a plane parallel to the cross section of the bars.

  FIG. 31 shows the finishing assembly of FIG. 27 configured as a stop bar, and used for a transition between a floor covering R and the ground, said finishing assembly being fixed to the ground by means of only the rail of FIG. The invention is not limited to the production of a multifunction assembly comprising three bars 1, 2 and 3, but can be generalized to produce a multifunction finish with at least two bars, on which is applied the same surface coating.

  For example, it is possible to make a multifunction assembly comprising only a T-bar 1 and a bar 2 and usable as a connecting bar or threshold bar, or even a multifunction assembly comprising only a T-bar 1 and a bar 3, and that can be used as a bar of 2881157 21 junction or stop bar.

  Also, the cross-sectional profiles of the bars of the finishing assemblies of the appended figures have been given solely as non-exhaustive exemplary embodiments, the invention not being limited to these profiles alone. The invention can thus be applied to produce multi-function floor covering finishing assemblies whose bars have profiles in cross section different from those illustrated in the accompanying figures. In addition, the bars of the finishing assembly of the invention, depending on their cross-sectional profiles, may where appropriate fulfill other functions than the functions illustrated in the figures (terminal bar, threshold bar or stop bar). In particular, it is within the scope of the invention to provide a finishing assembly for flooring which is suitable for use in other applications for flooring, and for example which can be configured for use as a stair nosing.
