Description

LATTE OR SIMILAR FOR COATING AND

  COATING COMPRISING AT LEAST ONE LATTE AS PRECEDED

  The present invention relates to a slat or the like for coating and in particular flooring and a coating comprising at least one slat as mentioned above.

  The invention will mainly find application in the production of slats for constituting a component of an indoor or outdoor flooring and in particular terraces.

  However, although particularly intended for such applications, the batten may also be used to compose a wall covering or ceiling.

  In the present application, it will be understood by batten or similar a substantially flat and flat shaped element such as board, board, blade, shingle, etc ...

  For the constitution of a flooring, a number of achievements has already been proposed on the market.

  In a first type of extremely simple embodiment, the flooring consists of simple boards that are just fixed by means of nails or screws, directly on the ground or on joists.

  This embodiment particularly easy to implement however has drawbacks and in particular the fact that the fasteners are visible.

  Furthermore, the fixing of screws or nails to the ground through plastic boards can cause cracks in the board, detrimental both in terms of aesthetics and in terms of the strength of the board, the cracks may in effect spread.

  According to another embodiment, it is provided that the boards are connected together by means of a connecting element, this connecting element being fixed to the ground again either directly or by means of joists.

  This second type of embodiment is advantageous since it makes it possible to avoid any aesthetic degradation at the level of the upper part of the boards. However, it requires special boards and in particular machined at their edges to be assembled by the fastener.

  In addition, the space between the boards of a generally fixed coating depends on the geometry of the fastener.

  Finally, the blades or planks being connected together, it is impossible to change a plank without removing the adjacent planks.

  Finally, according to a last embodiment, boards are made in several parts, one of the parts constituting the support being fixed to the ground and another part of different structure being fixed on the support by means of independent elements such as screws and nails.

  This type of embodiment is however not satisfactory considering the fact that the fixing means between the support and the upper part are visible and secondly, given the difficulty of making identical cuts on the lower part and the upper part to match them considering their different structures.

  The present invention aims to overcome the aforementioned drawbacks and to provide a slat or the like that can be fixed to the ground without the fasteners are apparent and without the batten is dependent on adjacent slats.

  Another object of the present invention is to provide a batten or the like made in two parts and whose upper part can be easily replaced in case of wear.

  Another object of the present invention is to provide a batten whose components can be produced industrially and in particular by extrusion from a single die.

  Another object of the present invention is to provide a batten whose structure allows easy cutting to adapt to the dimensions of the surface to be covered.

  The invention thus relates to a batten or the like for coating and in particular for flooring.

  According to the invention, said slat consists of two identical superimposed half-elements integrating assembly means between them for the formation of said slat.

  The invention also relates to a coating comprising at least one slat 5 as mentioned above.

  Other characteristics and advantages of the present invention will appear more clearly on reading the following description of a preferred embodiment in which the description is given by way of non-limiting example and with reference to attached drawings among which: - Figure 1 shows schematically in sectional view an example of batten made according to the invention; - Figure 2 shows one of the two half-elements forming the batten as shown in Figure 1; - Figure 3 shows a second embodiment of one of the two half-elements constituting the slat, according to the invention.

  Referring to Figure 1, we see a batten 1 consisting of two identical half-elements 2,3. These two half-elements 2,3 are superimposed and incorporate assembly means 4 between them allowing the formation of the lath 1.

  It can thus be seen in FIG. 1 that the half-element 2 is in a first position and that the second half-element 3 is in relation to the half-element 2 simply turned over so as to be superimposed on the half-element 2.

  The assembly means 4 as shown in Figures 1 to 3 comprise so-called deformable zones 5 for assembling the two half-elements 2,3 snap-fastening.

  According to an advantageous arrangement, it may also be provided that the assembly means 4 furthermore comprise, on each half-element 2,3, protrusions 6 and recesses 7 cooperating so as to reinforce the fastening between the two half-elements 2, 3.

  These protrusions 6 and recesses 7 are advantageously provided at the level of said deformable zones 5.

  Thus formed, the two half-elements 2,3 can be secured to each other without the need to use additional independent fasteners.

  This arrangement also makes it possible to replace the half-elements forming the upper surface without tools and without degrading the remaining half-element.

  For example, in case of damage to the upper half-element 3, we can easily remove this element to replace it with another nine.

  Fixing the lower half-element 2 either on the ground or on the joists can be carried out advantageously with the fastening elements such as screws or nails not shown in the accompanying drawings.

  For this purpose, it is provided that each half-element 2,3 has a zone of reduced thickness 8. This zone of reduced thickness 8 is able to be perforated by a fixing element to allow the connection of one of the half elements on the surface to be covered.

  The laying method of each slat 1 is extremely simple since it is first necessary to cut the half-elements 2,3 to the desired length and then to lay on the surface to be covered with the half-element 2.

  The following step consists in fixing this half-element 2 by means of one or more fixing elements and then in a following step of coming to cover this half-element 2 by a half-element 3 by pressing on the latter to cause, by the deformation of the deformable zones 5, the snapping of the part 3 on the part 2 thus forming the lath 1.

  In this regard, provision is made to facilitate the assembly of the two half-elements 2,3 that these half-elements comprise guide means 9 of a half-element 2 relative to the other.

  Referring to FIG. 3, it can be seen that these guide means 9 consist of the structure of the deformable zone 5.

  This structure has indeed a deformable zone 5 with a bell-shaped profile making it easy to insert the part having a bell-shaped profile in the corresponding hollow of the other half-element.

  It is also interesting to note that according to one characteristic of the invention shown in FIG. 3, each half-element 2,3 has at one end a flange 13 whose height is substantially equal to the width of the slat 1.

  In this way, it is possible to obtain slats 1 having a rim 13 integrally formed in one piece, which is advantageous for the realization of the slats covering the edge of the surface to be covered avoiding detachment of the two half-elements 2,3 in case of support exerted on the edge of lath 1.

  According to another advantageous characteristic of the invention, each half-element 2,3 is obtained by extrusion.

  It should be noted that these two elements being identical, only one die will be necessary to produce the half-element 2, 3.

  Preferably, these half-elements 2,3 will be made of plastic.

  In Figures 1 and 2, we see that the two half-elements 2,3 comprise a number of stiffeners 10 arranged to increase the rigidity of each half-element 2,3 requiring a reduced amount of material.

  Depending on the application and the coating, it will be possible to consider a greater or lesser number of stiffeners 10 and for example low when the coating is a wall covering and important when it comes to a floor covering.

  In the same way, many other deformable zone profiles could also have been envisaged.

  The invention also relates to a floor covering comprising a batten as aforesaid, the set of slats being able to be arranged regularly or irregularly and, for example, conventionally parallel to one another or else forming angles between them so as to constitute reasons.

  According to an advantageous characteristic of the invention, provision may also be made for each half-element 2,3 to comprise reliefs 12 making it possible to form a batten 1 having an anti-slip surface 11.

  Of course, other embodiments within the reach of those skilled in the art could have been envisaged without departing from the scope of the invention defined by the claims below.
