Cover strip for an upright scrubbing base

The present invention relates to a profile material for masking or covering the edge of a floor covering of the type carpet, fitted carpet or plastic covering on the scrubbing base of a wall, a partition wall or the like. The invention particularly relates to a profile material as a cover strip for an upright scrubbing base, i.e. for covering or masking the edge of a floor covering which is bent or folded up as a scrubbing base for vertical contact with a wall.

A known cover strip for an upright scrubbing base consists of a flat strip or flap for gripping under the vertical edge of the covering, whereby a free end of the strip or flap is provided with a fold or cuff projecting into the side facing away from the wall, which is intended to cover the cut surface of the floor covering after installation.

A disadvantage of this type of cover strip is that it is complicated to install, as it requires deformation of the edge of the floor covering during installation in order to fit it under the cover strip.

Another disadvantage is that maintaining the level when laying such a cover strip is critical.

Another disadvantage is that the wall corners, regardless of whether they are recessed or projecting corners,

Requires bevel trimming of the profiles, which results in imperfections in the final processing state.

A further disadvantage is that the covering of the edge of the covering by the covering part of the cover strip limits the possible height of the covering of the scouring base edge of the covering and therefore requires a precision in cutting the floor covering that is difficult to maintain.

Another disadvantage is that the material does not allow the end of a wall covering to be covered.

The present invention aims to create a new cover strip for floor coverings laid with an upright scrubbing base, which eliminates the disadvantages of the known cover strips.

The invention aims in particular to create a cover strip profile material that is easy to lay.

The invention also aims to create a cover strip whose installation is simplified as a level scrubbing base.

The invention also aims to increase the covering capacity for covering the edge of the floor covering laid with an upright scrubbing base by means of the cover strip.

The invention also aims to provide a cover strip which allows a perfection of the finishing state for recessed or projecting wall corners and which in particular does not require bevel trimming.

The invention further aims to provide a cover strip which not only allows the edge of a floor covering laid with an upright scrubbing base to be covered, but also the edge of a wall covering adjoining this scrubbing base to be covered.

To achieve these objectives, the present invention provides a profile material for receiving a cover strip for an edge of an upright scrubbing base of a floor covering, characterized in that it comprises a plate for bearing against a wall and for at least temporary connection between a strip or flap for resting on the floor and a head for receiving by means of a clip clamping at least one cover strip element.

According to one embodiment of the present invention, the plate has longitudinal ribs or grooves for engagement against the wall.

According to an embodiment of the present invention, said ribs form guides for cutting the profile material in height.

According to an embodiment of the present invention, the connection between said plate for bearing against the wall and said strip or flap for resting on the floor is made in cross section by means of an inclined surface.

According to an embodiment of the present invention, said head projects in cross-section from the side opposite the wall and has a groove for receiving a clip-clamping head of the cover strip element.

The invention also provides a corner cover strip for an upright skirting board of a floor covering, characterized in that it has, in cross-section, a head protruding into the interior of the cover strip for clip-clamping in at least one carrier profile material attached to a wall, as well as two legs extending on both sides of said head; and that the corner cover strip consists of two straight sections which together form a corner angle.

According to one embodiment of the present invention, the two sections have a length in the range between 2 and 20 cm.

According to an embodiment of the present invention, the head extends continuously over the entire inner length of the cover strip, which is intended for a projecting corner of a wall.

According to an embodiment of the present invention, it is provided that said head is interrupted and missing in the corner region, wherein the cover strip is intended for a re-entrant corner of a wall.

The invention also provides a cover strip profile material for the upright scrubbing base of a floor covering, characterized in that the cover strip has a fastening profile material and at least one cover strip profile material which in cross section comprises two legs which extend on both sides of a head which projects into the interior of the cover strip and is intended for clip-clamping in the carrier profile material fastened to a wall.

·

The present invention further provides a cover strip for an upright scrubbing base of a floor covering, wherein the cover strip has a fastening profile material and at least one cover strip that can be installed by means of a clip-clamp connection.

These and other objects, characteristics, features and advantages of the present invention will be explained in detail in the following description of specific, non-limiting embodiments, with reference to the accompanying drawing figures, in which:

Fig. 1 shows a cross-sectional view of a profile material of an upright scrubbing base and its cover strip according to an embodiment of the present invention,

Fig. 2 shows in perspective view and in section a cover strip for an upright scrubbing base in attachment according to an embodiment of the present invention,

Fig. 3 is a perspective view of the assembly of a cover strip for an upright scrubbing base on a projecting corner, according to an embodiment of the present invention,

Fig. 4 shows in perspective view an embodiment of a cover strip element for a re-entrant corner, according to the present invention.

For reasons of clarity and brevity, identical elements in the various figures, which are not drawn to scale, are designated by the same reference numerals.

Fig. 1 shows a sectional view of a profile material 1 of an upright scrubbing base according to an embodiment of the invention and a cover strip 2 which can be clipped onto the profile 1. According to the invention, the cover strip for the upright scrubbing base consists of two elements. A first element consists of the profile material 1, which is intended for fastening to the wall and/or to the floor. A second element is formed by the actual cover strip 2, which, as described below, is intended for clip-clamping onto the profile 1 after laying the floor covering with upright scrubbing base, and optionally a wall covering.

The structure of the profile material as a cover strip for a scrubbing base according to Fig. 1 is also described in connection with Fig. 2, which shows a perspective view and a section of a profile material as a cover strip for a scrubbing base in the installed state.

According to the invention, the profile material 1 in sectional view essentially consists of three parts.

A first part forms a plate 11 for supporting or abutting against the wall (M, Fig. 2), namely at its base or plinth. Preferably, the plate 11 is not completely flat, but, as can best be seen in Fig. 1, is provided with longitudinal, i.e. horizontal ribs or grooves 12. These ribs or grooves 12 are arranged on both sides of the plate 11, i.e. both on the side facing the wall M and on the opposite side or surface, which serve to receive the inside of a floor covering (R, Fig. 2) which is directed upwards as a scrubbing plinth.

A second part of the profile material 1 consists of a strip 13 resting on the floor (S, Fig. 2). This support strip or tab 13 engages under the floor covering R in its horizontal area.

The parts 11 and 13 are connected to each other. According to a preferred embodiment of the invention, this connection is not made at a right angle, but consists of a surface 14 which is inclined in section. Such an inclined surface 14 allows the laying of the profile material 1 even if the corner between the wall M and the floor S is not perfectly rectangular.

From the foregoing it follows that the laying of the profile material 1 is carried out in such a way that the strip 13 rests on the ground and the plate 11 rests against the wall. The profile material 1 can be attached to the wall and/or the ground by any means. Preferably it is glued or screwed to the wall.

The ribs 12 fulfill several tasks. On the wall side (M), a first role is to optimize the holding adhesion of the profile material by means of bonding, in that the plate 11 is given a roughness.

Compared to the floor covering R, the ribs 12 allow, again by means of roughness, a temporary support of the back of the floor covering R, which may be, for example, a carpet, a fitted carpet or a PVC covering.

Another role of the ribs 12 is that, insofar as they run longitudinally and parallel to each other, they form a guide during possible cutting if the height

the plate 11 would not be sufficient for the desired height of the scrubbing base. The invention therefore has the advantage that it ensures that the risk of damage to the profile material due to deflection of the knife- or cutter-shaped cutting tool when laying the profile material is avoided.

A third part of the profile material 1 consists of a terminal head 15 in the upper part of the cross-section. The head 15 is located on the rear in the extension of the plate 11 and protrudes on the opposite side. The head 15 forms a longitudinal groove or groove 16 for receiving a clip clamp head 21 of the cover strip 2.

The cover strip 2 is also designed as a profile material and preferably has a convex shape curved outwards. Its outer surface 23 forms the final outer surface of the cover strip and has the desired decorative or ornamental elements (color, surface appearance, etc.).

In cross-section, the head 21 preferably has a multi-stage dovetail shape (for example with two or three teeth) and engages with play in a corresponding counter-shape in the groove 16. The head 21 protrudes from an inner surface 22 of the profile material 2 and preferably extends over the entire length of the profile material. An exception to this, however, applies in connection with Fig. 4 for a re-entrant corner angle profile, as described further below. A first arm or leg 24 of the cover strip 2 extends from the base of the head 21 and is intended with its free end 25 to rest against the exposed visible surface of the covering R (preferably with a slight pressure due to the clip-clamping connection of the head 21 in the groove 16 and the thickness of the covering R in conjunction with an elasticity

act of the leg 25). A second arm or leg 26 goes from the base of the head 21 to the upper end of the profile material 2 of the cover strip and is intended to rest with its free end against the wall M above the profile material 1 or against any wall cladding RM. The leg 2 therefore also forms a joint cover strip of the wall covering RM, the edge of which can rest against the top of the head 15 if it is a thick covering (for example a stretch wall carpet). If it is a thin covering such as wallpaper, the latter can, for example, extend under the part 11 if it is laid in front of the profile material 1, or be cut off at the level of the head, its edge then being masked or covered by the leg 26.

The clip-clamp connection is preferably detachable, i.e. the cover strip 2 is removable from the profile material 1. It can therefore be changed, for example to adapt its decor in the event of a change in the floor and/or wall covering, without the profile material 1 having to be changed for this purpose, as would be the case with a conventional one-piece profile material as an upwardly extending washing or scrubbing strip.

According to a preferred embodiment, as illustrated for example in the figures, the arms or legs 24 and 26 are not symmetrical with respect to the head 21 in order to take into account differences in thickness between the floor covering R used as a scrubbing base and the possible wall covering RM. In particular, in the resting state (i.e. without the elastic support), the profile material 2 is preferably shaped such that when the head 21 is aligned horizontally, the end 27 of the leg 26 extends vertically beyond the head 21, while the end 25 of the leg 24, on the other hand,

above this vertical, as illustrated in Fig. 1 .

The cross-sectional height of the leg 24 determines the tolerance for cutting the edge of the scouring base overlay of the covering R. It will be appreciated in this respect that this height is not limited by the deformability of the leg 24. In fact, it is no longer necessary to enclose the covering under the covering leg, as is the case for certain known covering strips of erected scouring bases.

Preferably, the profile materials 1 and 2 are made of plastic material. The profile material 1 is made of a plastic material, the rigidity of which is chosen so that it has sufficient strength for handling when laying with a scrubbing base, taking into account the height of the panel 11. The rigidity also takes into account the fact that this profile material is formed in one piece and that the head 15 must have sufficient mechanical strength for locking the head 21 of the profile material 2 by means of a clip clamp.

Preferably, this rigidity is chosen so that, with the assistance of the two bends which allow the connection of the parts 11 and 13 by the inclined surface 14, it gives the lower part of the profile material 1 a certain flexibility for adaptation to wall and floor corners which are not necessarily right-angled.

The rigidity of the profile material 2 is chosen so as to allow sufficient deformation of the legs 24 and 26 to adapt to different thicknesses of the covering R and to enable the clip clamping of the head 21 in the groove 16 of the head 15.

An advantage of the present invention is that it allows for simplified installation of the cover strip for the floor covering with the scrubbing area folded upwards.

Another advantage of the present invention is that it allows, using one and the same support profile material (profile material 1), assembly without longitudinal cutting, ensuring a horizontal level or at least parallel to the ground for the upper edge of the rubbing strip, or, using cutting through the ribs 12, assembly of the profile material 1 in two parts, ensuring a rubbing strip with a horizontal upper edge, even when the ground is not horizontal.

The invention is suitable for any floor covering, provided that it is sufficiently flexible to accommodate an upwardly folded skirting board area. Examples include fitted carpets, rugs and plastic coverings, for example made of PVC, in sanitary rooms. In the latter application, an upwardly folded skirting board ensures that the covering seals the wall area.

Fig. 3 shows a perspective view of a projecting corner 30 of a wall M and illustrates the installation of a cover strip for an upwardly curved skirting area according to the invention. The use of a system consisting of two parts (fastening or support profile material 1 and the cover strip itself) considerably facilitates installation and improves the final appearance of the wall corner.

In the example according to Fig. 3, straight sections la and lb of fastening profile material are cut off in the manner shown in Figs. 1 and 2 and fastened, for example glued or screwed, to the lower end of the wall M. According to the invention, the sections do not need to be cut diagonally for a perfect joining together. The sections simply correspond to the respective lengths of the straight wall sections to be covered, the ends of the profiles la and lb ending substantially in the corner 30 of the wall, as illustrated in Fig. 3.

According to the invention, after the floor covering with a scrubbing skirting has been laid, a cover strip element 2s, the visible (outer) side of which forms a projecting angle, is used to cover the angle or corner. This element 2s forms a modular element of the cover strip system according to the invention. The element 2s comprises two straight sections 28s which are connected to one another to form a corner angle and each have a similar structure to the cover strip 2 described above. Their length can, for example, have a value in the range between a few centimeters (for example 2 cm) and a few decimetres (for example 20 cm). This length is preferably chosen so that it is, on the one hand, sufficiently small to adapt to the various configurations constantly encountered in buildings and, on the other hand, sufficiently large so that the clip clamping head 21 (not shown in Fig. 3) on the inside of the profile material 2s has a sufficient engagement and overlap length in the profiles la and lb, taking into account the fact that in the corner 30 itself the wall lacks the groove 16 as a result of the straight cuts. For a projecting corner (Fig. 3), the clip head 21 can run continuously over the entire profile piece 2s and thus also form a corner.

As can be seen, as with the straight cover strips did, sections 28s can be cut lengthwise for optimum adaptation. Straight cover strips 2 are attached to both sides of the corner 2s in the manner described in connection with Fig. 2.

Fig. 4 illustrates a profile element 2r according to the present invention for a re-entrant corner. As in the case of the element 2s, the element 2r consists of two straight sections 28r of predetermined length which can be cut to size and which abut one another to form the corner 31 of the element 2r. The sections 28r have the same cross-section as the cover strip 2. The element 2r is intended to engage or be inserted into two support profiles (not shown in Fig. 4) which are laid on either side of a re-entrant corner in a wall.

As with the projecting corner, the profile materials according to the invention can be cut straight (and even only approximately) during installation, and not necessarily at an angle. For example, one of the skirting or fastening profiles 1 can be cut so that it rests against the re-entrant angle, while the other skirting profile is cut so that it rests against the head 15 (on its open side). According to a variant, the profiles 1 are cut so that they leave a gap at the corner of the wall. The strips or tabs 13 of the profiles in question can overlap without this being a hindrance to the floor covering.

In order to accommodate the thickness or depth of the head 15 of one of the two support profiles, the clip clamp head of the element 2r preferably consists of two non-connected

Pieces or sections 29r that do not extend into the corner 31. The distance between the respective end of each head section 29r and the corner 31 is, for example, selected such that it is greater than the thickness or depth of the head 15 of the profiles 1. In this way, the element 2r can be clamped onto the two profiles laid in a re-entrant corner without having to pay attention to a specific cut of these profiles.

As in the case of a projecting corner, straight cover strips 2 are then placed against the free corners of the element 2r on the straight wall parts.

An advantage of the present invention is the provision of a modular system for assembling cover strips for upright skirting boards, the system preferably comprising only four elements. A first element is the fastening or support profile 1, which is always the same regardless of the type of installation (in one piece, as a re-entrant or projecting corner, or in two pieces after being split to adapt to a skirting board height greater than the height of the part 11). A second element is the rectilinear cover strip profile 2, which can be cut to size according to the length of the skirting boards to be covered. A third element is formed by the element 2s for a projecting corner, a fourth element by the element 2r for a re-entrant corner. These four elements make it possible to produce cover strips for upright skirting boards according to different corners and routes in a room, while ensuring an optimal state of finish.

According to a preferred embodiment, the plastic material forming the profiles and the elements 2r and 2s is sufficiently flexible or elastic to allow slight deformation

and to adapt to deviations of the walls from straightness. The fastening or support profiles 1 are then cut into pieces according to the respective changes in the floor plan of the wall. In the same way, the elements 2s and 2r are given a certain flexibility or resilience in order to adapt the system according to the invention to recessed or projecting corners that are not necessarily exactly right-angled. On the other hand, no changes are required on the part of the profile material 1. In particular, no cutting at an angle is required.

Although this is not a preferred embodiment, it does not exclude the realization of corners without special elements (2s or 2r), but by bevel cutting of profiles 2. According to a variant, the deformability of the profiles 2 can be increased by heating.

The present invention allows various variations and modifications that will occur to those skilled in the art. In particular, the choice of materials for the various profile materials is left to the person skilled in the art, based on the functional information given above and the specific application. Furthermore, the dimensions of the profile materials can be staggered according to different product ranges, again depending on the specific application. For example, different sizes (heights) of the profile 1 can be provided, taking into account the heights generally provided for scrubbing bases, which are in the range between 5 and 30 cm. Furthermore, although the plastic version is the preferred embodiment, the invention is also suitable for use with other materials. For example, aluminum can be used for the profiles 1 and 2 and the elements 2r and 2s, but at the expense of a loss of flexibility and

Deformability. Finally, it is possible to provide a range of corner elements with angles different from 90° (for example in steps of 10 or 15°) for a more precise adaptation to different configurations.
