Description

FLOOR COATING WITH PLATEHE UP AND METHOD OF INSTALLATION

The invention relates to the technical sector of floor coverings and more particularly to the rise in plinth angle reentrant or outgoing angle, and along the walls.

The problem of raising the plinth is well known because the operator ensuring the installation of flooring in a room must ensure that the skirting is done in the best aesthetic conditions, sealing avoiding creases apparent coating. Raising the skirting relates to the three zones corresponding successively to the junction between the ground and the walls of the vertical wall which are established in a continuous plane, and also for the incoming and / or outgoing corner portions.

As far as the Applicant is aware, the problem of raising the plinths of the floor coverings has so far been considered separately between, on the one hand, the plinth lifts at an angle in or out, and on the other hand, on the long areas corresponding to the ground-wall junction along the straight walls of the said walls.

Regarding the skirting lifts in outgoing angle or in re-entrant angle, it has been proposed many solutions hereafter identified but not limited.

It is thus known to make skirting lifts for re-entrant angle or outgoing angle by conventional heating or folding methods for their shaping and their plating against the walls of the corresponding walls. It is also well known to make skirting lifts in the form of monobloc modules which are preformed and which fit in particular at an angle entering the space formed between the floor and the consecutive wall corner walls.

The problem lies in the fact that the angle configurations are not perfect or standardized so that the operations to be performed are not always very easy to perform or require heating means and equipment to allow the creep of the constituent material modules.

In addition, the shaping of skirting board lifts by heating and folding finds limits with the thickness of the skirting lift itself which does not always then provide the necessary flexibility.

With regard to the rise in the plinth along the wall walls which are continuous and vertical, the flooring is generally positioned as close as possible to the wall wall and then a strip of floor covering is added vertically which can be maintained by a slide support.

Patent US Pat. No. 6,354,057 describes the production of modules in the form of two-part profiled skirting boards resting against the ground and against the part of the wall connected together by a sloping joining strip and connected to the other preceding parts by grooves. joint and junction revealing apparent fold zones and being breakouts and breaks in case of strong support. In addition to the risk of rupture, connection zone between the ground support portion and the connecting strip, it is shown a water retention zone. The thickness in all the parts considered is the same. US Pat. No. 3,092,869 also discloses a support angle profile for receiving carpets. This profile has on its flat part resting on the ground a profile rounded tail for the reception of an anchoring piece with nail attachment to the carpet. The section and thickness of the carpet is always the same in all its parts. It is a simple angle gear that is not part of its integrity of the actual flooring.

These patents - US Pat. No. 6,354,057 and US Pat. No. 3,092,869 - are absolutely useless in the context of the approval of clean rooms requiring very precise and strict conditions of installation and sanitary hygiene.

The Applicant's approach was therefore to reflect on this issue in order to seek a global solution that can allow the return to plinth not only in re-entrant angle or outgoing angle but also along the walls of walls, more or less great length between two consecutive outgoing angles or two consecutive incoming angles or a consecutive outgoing angle and outgoing angle.

Thus, the Applicant's overall approach has been to reconsider the characteristics of the floor covering disposed on a flat surface to be covered, with the parts of plinthing up all around the peripheral periphery of said surface. This approach has been made necessary in particular and not limited to meet the need for floor coverings to cover the surfaces in 'white' rooms, that is to say, rooms intended for medical and hospital uses. These require very stringent installation requirements to meet health and hygiene and maintenance requirements. In this case, the floor covering is welded with the skirting modules.

The problem encountered also lies in the fact that there is a continuity of thickness on the coating portion in floor covering, while allowing the return to plinth.

Another constraint lay in the flexibility capabilities of floor coverings for shaping them in a vertical plane relative to the horizontal main plane.

The Applicant has thus devised a technical solution that perfectly meets the needs and requirements mentioned above, and this, in a continuity of pose.

According to a first characteristic, the floor covering with skirting in the form of one or more module (s), each module comprising a first zone placed on the flat part of the ground to be covered, a second zone bearing against the corresponding vertical wall part wall and a transition zone between said first and second parts, is remarkable in that each module comprises a first zone whose thickness is equal and identical to the thickness of the flooring placed on the flat part of the soil to be covered, and a second zone whose thickness is smaller than the thickness of the first zone to give a capacity of flexibility to said second zone, and in that the transition between said first zone and said second zone of each module is performed by a progressive sloping profile bevel disposed on the reverse side of the module, and in that the said first zone bears on the ground and the said second zone is supported against the vertical walls of the corresponding wall portions, and in that the beveled profile joining with the said second zone comes to bear on an angle profile (4). According to another feature, the said floor covering and the said plinth lift are made in the same structure and the same material, the said covering covering the floor with the exception of a peripheral edge around the ground-wall connection to allow the positioning of different modules constituting the skirting up along the connection zone between the floor and the walls, the re-entrant corner parts, the outgoing corner portions, and that the shapes and dimensions are adapted to ensure the transition between the floor and the walls in their length between two consecutive incoming and / or outgoing corner profiles, and in that said first zone is placed on the flat part of the floor at the edge of the border peripheral, and in that said second zone bearing against the vertical walls of the corresponding wall portions.

According to another characteristic, the floor covering and the skirting module are monolayer, and in that the skirting module comprises a first zone of a first thickness and a second zone of a second different thickness and lower at the said first thickness. According to another characteristic, the floor covering and the plinth lift module are multilayer, and in that the module comprises a first zone in ground support defined by all the layers of thicknesses, and a second zone to come into support against the wall walls of a lesser thickness.

According to another characteristic of the invention, the floor covering and the plinth lift module are electrically conductive. According to another characteristic, the skirting module is placed in abutment against a pre-established angle profile disposed between the ground part and the wall part.

These and other characteristics will be apparent from the rest of the description.

For fixing the object of the invention illustrated in a non-limiting manner to the figures of the drawings in which: FIG. 1 is a perspective view illustrating the laying of a floor covering with different modules constituting skirting lifts along the ground-wall connections, in the form of a re-entrant angle, in the form of an outgoing angle, FIGS. 2A, 2B, 2C are bottom views of the modules of the skirting lifts according to the invention in the successive configurations connection between floor and wall , connection at re-entrant angle, outgoing angle connection, FIG. 3 is an alternative view of a module for a re-entrant angle,

FIG. 4 is a sectional view of a multilayer module; FIG. 5 is a side view illustrating the positioning of the module along a ground and wall connection zone;

Figure 6 is a schematic view illustrating the installation of two consecutive modules in outgoing angle and re-entrant angle.

In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.

For the understanding of the invention is shown a room (L) for receiving on the ground (S) a coating (1) with a rise in plinth along the walls (M). The term 'local' is used in general to identify any habitable area that may receive floor coverings with floor and raised plinth applications. This room can have any use and application in medical and hospital environments or other.

According to the invention, the floor covering is effected by a floor covering (1) which can be monolayer or multilayer and having a constant thickness (El). The structure of the flooring is established in any appropriate and known manner and may be single material or multi-material and may or may not include conductive parts, materials or carbon fibers. This floor covering (1) covers almost the entire floor surface leaving a continuous peripheral edge (2) for the positioning of different types of modules (3) ensuring the function of skirting. The peripheral border (2) is therefore established over a certain width sufficient to allow the positioning of said modules at the locations in question and the rise in plinth in the continuous portions of transition between floor and wall in their length, located between two profiles entering angle and / or consecutive outgoing angle, the recovery of the profiles of re-entrant angle and the overlap of outgoing corner profiles.

According to the invention, said modules (3) comprise a first zone (3.1) whose thickness (E2) is equal to and identical to the thickness of the floor covering laid down having the same constitutive characteristics of structure and material. This first zone (3.1) is placed on the flat part of the ground at the location of the peripheral edge (2). The module also comprises a second zone (3.2) whose thickness (E3) is smaller than the thickness (E2) of the first zone to give a flexibility capacity to said second zone. The transition between said first zone (3.1) and said second zone (3.2) is effected by a profile (3.3) sloping, progressive and bevel, disposed on the reverse face of the module, the beveled portion joining with the said second zone. Said second zone (3.2) is intended to bear after shaping and flexibility against the vertical walls of the corresponding wall parts. To facilitate the positioning of said modules, there is a pre-established angle profile (4) between the ground part and the wall part, this angle profile (4) being configured to adapt to the different places of installation between ground and wall, along the vertical walls of these, in the coming angles, in the outgoing angles. The angle profile (4) thus has a horizontal base plane (4.a) and an adjacent vertical plane (4.b) against the wall, as well as a curvilinear shape (4.c) of connection between the ends horizontal and vertical basic plans.

The configuration of the angle profile (4) is adapted to its positioning zone. Under these conditions, the second zone (3.2) of the module overlaps the aforementioned angle profile and overflows vertically with respect to the latter, the connection being effected by gluing. The first zone (3.1) of the module is positioned on the ground in a space formed in the peripheral edge (2), then the module is shaped in any known manner to come to bear against the corner profile and the wall. corresponding wall. The beveled shape (3.3) perfectly fits the curvature of the angle profile (4).

FIGS. (2A) (2B) (2C) are shown in a view from below of the possible configurations of the modules. The first zone (3.1) is materialized as the case may be by a strip (3.1a) of great length, by an 'L' shape (3.1b) for the outgoing angles, by a square shape (3.1c) for the angles returning. These forms are not limiting and FIG. 3 shows another configuration (3.ld).

As a nonlimiting example, indications of the thickness of the flooring and the modules (3) in their different zones are given. The thickness (El) of the floor covering placed on the surface of the ground is for example of the order of 5 mm. The thickness (E2) of each zone (3.1) of the module (3) is therefore 5 mm. The thickness (E3) of the second zone (3.2) of the module is for example of the order of 2 to 3 mm. The width of the progressive beveled portion (3.3) is of the order of 1 to 2 cm. The reduction in thickness obtained on the zone (E3) gives it flexibility allowing the operator to be shaped along the vertical walls of the wall in the various constituent parts of the room including the re-entrant angle, the outgoing angle. The realization of floor coverings (1) and modules in skirting (3) is designed in the same way. If the floor covering (1) is monolayer, of a thickness (El), the up-plinth module will be monolayer with a differentiated thickness between the areas (3.1) and (3.2). If the floor covering is bilayered or multilayered with different materials, the up-plinth module will have an upper layer corresponding to the top layer of the flooring and will or may not have one or more lower layers but still in a dimensional ratio of lesser thickness for zone (3.2) compared to zone (3.1).

According to the invention and the laying method, the operator will therefore first position the floor covering (1) on the entire surface of the room excluding the peripheral edge (2). The operator will then place the corner profiles (4) on the perimeter of the connection between floor and wall. He will then position the different modules at the appropriate places on the peripheral edge with the ground support of the thickest zone (E2) against the jointing edge of the flooring. The operator will then shape the zone (3.2) of the module by deformation and folding thanks to the flexibility of this zone and this using any known means. It will glue on the corner profile and on the vertical wall of the wall of the zone (3.2)

The configuration of the modules (3) can be pre-established in various shapes and sizes as required. The thickness reduction between the zones (3.2) and (3.3) is obtained either during the manufacture of the module or by a machining operation. The floor covering and the various modules are made according to a design that allows them to be electrically conductive.

Thus, according to the invention, the complete treatment of the room to be coated is carried out with an optimization of the sanitary conditions of maintenance and hygiene.
