Description

MULTIFUNCTIONAL PROFILE FOR TRAPRENOVATION

The present invention has for its object to manufacture a profile or system for renovating a staircase. More in particular, the invention relates to a multifunctional stair renovation system comprising at least two panel-shaped elements (profiles) that can be attached in or to each other, preferably via a snap connection, so that there are several options available for finishing a staircase.

State of the art

The craftsman has several options for renovating a staircase. For example, there are profiles that can be glued onto an existing staircase. These usually consist of two parts (panels), namely a part that mainly covers the horizontal part of the stair step and often has a stair nose (nose part), and a second part that mainly covers the vertical part of the staircase. The second part, which essentially has to cover the vertical part of the stair step, is usually mounted behind the stair nose of the first part, which mainly covers the horizontal part of the stair step. The second part that covers the vertical part of the stair step can also be mounted at an angle so that the step becomes slightly larger.

In a known alternative manner, the vertical panel can be clicked at the bottom of the horizontal panel at an angle of 90 °, so that the vertical part fits almost seamlessly onto the horizontal part, so that a more tighter whole is obtained by avoiding the stair nose.

The panels or profiles can be made of MDF, chipboard, a wood-based plate, a WPC, a plastic, a solid or a semi-solid panel or profile. These panels may or may not be provided with a decorative covering layer consisting of, for example: CPL, HPL, LVT, a veneer, a solid wooden top layer, a cushion vinyl, a scratch-resistant paper, etc ... These cover layers are often provided with a scratch-resistant top layer. in the form of a transparent top layer,

BE2017 / 5750 a lacquer, a transparency wear layer that must protect the stair profile against scratches and / or wear.

Another known way is that an extra angle profile is used that forms the angle between the horizontal and the vertical panel. This corner profile can be made from a metal, a plastic, from wood or from a wood-based profile, whether or not provided with a decorative covering layer. These profiles and / or the stair profiles can also be provided with a non-slip zone.

The stair profiles are mounted on the existing stair with the help of an adhesive or silicone and / or by means of nails or screws.

The various possible finishing options are broadly: a straight staircase finish (90 ° with respect to the upper surface of the step), a Z-step (± 105 ° with regard to the upper surface of the step) and a stair nose (the vertical panel behind the stair nose of the horizontal panel that is at 90 ° or at a different angle to the top surface of the step). There is also a possibility to choose an open staircase, with this finish the vertical part is omitted.

The finishing options or stair renovation profiles described above each have a major disadvantage, and that is that the person skilled in the art is very limited in terms of finishing. The existing stair profiles are manufactured in such a way that the person skilled in the art must either work with a stair nose or work with a straight (90 °) stair or obtain a Ztrap, the vertical part being at an angle (+ - 105 °). In other words, people need different profiles to meet the wishes of the customer.

The object of this invention is to provide a multifunctional stair renovation system (profile) that allows the person skilled in the art or installer to renovate a staircase according to a straight staircase (90 °), a Z-staircase (+ -105 °) or with a staircase nose.

BE2017 / 5750

The object of the invention is achieved with the multifunctional stair system as defined in the independent claim. Preferred embodiments are described in the dependent claims.

Various things need to be taken into account when developing such a system.

With a Z-stage and with a straight stair (90 °), the challenge is that the transition from the horizontal part to the vertical part is as seamless as possible, both at 90 ° and with a Z-step (angle alpha = ± 105 °).

1) Easy assembly and easy to cut to size

A very important item is that the plate star must be able to cut both the panel covering the horizontal surface of the stair step as well as the panel covering the vertical part of the stair step to size. After all, the panels have fixed dimensions and the stair profile has to be adjusted or sawn according to the staircase that it has to cover. This is usually done by d.mv. a jigsaw or with a circular saw.

If we were to provide a solution for the above stated objective in the form of a stair profile in which the horizontal part and the vertical part are in 1 piece, this would be very impractical to shorten this stair profile to the correct size.

Measuring these dimensions is done with a special mold or workpiece that measures the dimensions of the stair step and which is then placed on the stair profile to shorten it to the correct dimensions, this makes it for the do-it-yourselfer and for the skilled in the art relatively easy. The intended objective can therefore best be achieved by offering a system that consists of two separate panels that can easily be clicked together or connected.

BE2017 / 5750

2) Seamless connection between the horizontal part and the vertical part

As already mentioned, it is very important to develop a system that makes the connection between the horizontal panel and the vertical panel as seamless as possible. A known way to achieve this is by using. a click system or clamping system. In the floor covering sector, this is a well-known technique for joining 2 or more panels without glue.

The technology we use is very close to that, however, the click system must be designed in such a way that the vertical panel can be tucked further than 90 ° and also in this case the connection between the 2 panels must be perfect (as good as possible) to connect.

3) Solution against the warping of the stair profiles

A stair renovation profile is usually provided with a decorative layer. This can be a CPL, an HPL, an LVT, a Vinyl or a paper decor layer that has the necessary scratch resistance.

Depending on whether these stair profiles are glued on one side or provided with a backing, these panels will warp, albeit very lightly, since different materials are used. The click system to connect the horizontal panel to the vertical must be such that the 2 panels still easily snap together. The click system must also ensure that the curvature is straightened in order to achieve a virtually seamless transition from the horizontal panel to the vertical panel after assembly.

In the following detailed description of the product as well as the method according to the present invention and the stair profiles thus formed, the features and advantages of the invention are further clarified. It is clear that the sole purpose of this description is to clarify the general principles of this invention by a concrete example, and that nothing in this description can therefore be interpreted as limiting the scope of

BE2017 / 5750 neither the patent rights claimed in the claims nor the scope of this invention.

Fig 1: Stair renovation system according to the invention. 2 panels (1,2) are shown on the image. The 2 profiles (1,2) have a carrier material (10) on which a decorative top layer (3) is applied. This decorative top layer (3) can be constructed from a decorative layer with a scratch-resistant top layer on top or can be a decorative layer that is already sufficiently scratch-resistant. These top layers have been known for a long time and can be paper foils, a plastic foil (PVC, PP, pet ...), a CPL, an HPL, an LVT, a vinyl, veneer, wood ... etc. These decorative top layers (3) can be provided with a specific decor such as a wood imitation, a stone imitation or the like. It is clear that the decorative top layer (3) does not necessarily have to be scratch-resistant. Thus, after mounting, the profiles can also be provided with a lacquer or an oil that makes the whole sufficiently scratch-resistant. It is also clear that according to the invention the decorative top layer (3) is not necessary. For example, the finishing layer may be applied to it after mounting stair profiles. Just think of covering vinyl or carpet on the stair profiles. The rear of the panels or profiles (1,2) can be provided with a backing (4) (foil on the back), but this is also not necessary in many cases. The carrier material (10) can be of a different nature, for example, these profiles can be composed of a PVC, a

BE2017 / 5750 plastic, an MDF, an LDF, an HDF, chipboard or other wood-based board material or solid wood. The profiles can be manufactured by means of extrusion or by profiling a sheet material as discussed further later in this document.

The first profile (1) mainly consists of a horizontal section that continues downwards on the right-hand side to a shorter vertical section. This vertical part can be considered as a nose part that covers a small part of the vertical part of the stair step. The horizontal portion of the first stair profile (1) has an upper surface (Vb). This top surface is essentially horizontal after mounting and will be considered in this document as a reference surface to define certain angles. The longitudinal end of said relatively short vertical portion is provided with a coupling part (K) which serves to ^{2, the} panel (2) can be clamped to record. This short vertical part can also be considered as a nose part. It is clear that other versions of this first profile (1) are possible. The coupling part (KI) can thus be provided directly in the horizontal part without a short vertical part being present. The vertical part may, in specific cases, be indicated in terms of aesthetics and / or strength of the stair profile, which will be discussed in more detail later in this document.

The short vertical part of the first panel (1) contains a plane VI that ends in point P1. We can easily state that the coupling part (Kl) is located at the bottom of the first panel (1) or profile. It is also the case that not every version will have a vertical surface (VI), so the transition from the horizontal top surface (Vb) to the point (P1) can be an arc.

The ^{2, the} profile (2) is substantially constructed vertically with respect to the top face (Vb) of the first panel (1). The upper side of the vertical part (2) contains a coupling part (K2) which can be clampably received in the coupling part (K1) of the first panel (1). The carrier material (10) of the second ^panel (2) may have the same structure as the carrier material (10) of the l ^th panel, but can also be different, as well as the decorative top layer (3) of the second ^panel (2) . The 2 coupling parts (K1, K2) are designed or designed in such a way that the 2 panels or profiles (1,2) can be clamped

BE2017 / 5750 can be coupled in this way that the plane (Vl) of the first panel (l) and the front face (V2) of the second ^panel (2) in the coupled state, run parallel to each other and in that the two points (Pl and P2) contact each other. It is also the case that the plane (VI) is perpendicular to the upper plane (Vb). The ^{2, the} panel (2), one can, depending on the desired implementation of the staircase renovation, continue turning or rotating with contact points (Pl and P2) as the center point is reached until the desired angle between the two planes (Vb, and V2). Both in the coupled state where the planes (Vb and V2) are perpendicular as well as in the coupled state where the plane (V2) is at an angle (Alfa + 90 °) with respect to the plane (Vb), the points ( P1 and P2). This implementation is explained further in the document. It is understood that tolerances may occur which may result in a minimal play between the 2 contact points (P1 and P2), but this has very little effect on the aesthetic of the end result and thus does not detract from the innovative and innovative character. of this invention.

FIG. 2a: Transvstccm according to the invention according to a straight-step version. The coupling means (K2) of ^the second panel (2) can be clamped in the coupling means (K) of the first panel (L) through which the first panel and ^the second panel (2) are connected to each other. The first panel (1) and the second ^panel (2) are connected to one another both in the direction (Dl) as well as in the direction (D2). The face (Vb) of the first panel (l) and the plane (V2) of the second ^panel (2) are substantially perpendicular to each other. This implementation of stair renovation is known as a straight staircase. Another known embodiment is a Z-stage in which the second ^panel (2) is rotated further than + -90 ° with respect to upper face (Vb). This implementation is explained further in this document. On the detail of the clamping parts (K1 and K2) we can see that the points (P1 and P2) make contact with each other. The first clamping part (K1) has a groove which is bounded at the top by lip (6) and bounded at the bottom by lip (5).

Fig 2b: Detail A of Fig. 2a of the clamping parts (K1 and K2) according to the invention. It can be clearly seen in detail A that lip (5) protrudes beyond the lip (6). This

BE2017 / 5750 has the reason to guarantee easy assembly and disassembly. It can also be an advantage that the lower lip (5) is elastic or flexible, this has the advantage that the clamping part (Kl) can absorb tolerances and this flexibility also allows the 2 panels to be mounted by means of a snap movement (S1; see Figure 5).

The points (P1 and P2) are in the same plane as (VI and V2). However, this may not be necessary, for example, the planes (V1 and V2) may be parallel to each other but not in the same plane, it may also be that the points (P1 and P2) are not in the same plane as the planes (V1 and / or V2). This is discussed further in this document.

Fig 3a: Stair system according to the invention according to a Z-step version. The coupling means (K2) of ^the second panel (2) can be clamped in the coupling means (K) of the first panel (1), whereby the first panel and the second ^panel (2) are connected to each other. The plane (V2) of the second ^panel is at an angle alpha is rotated further with respect to plane (VI). This type of stair version has a Z-stage. On average, the angle alpha is 15 °. However, this can be different from step to step. The angle (Beta) is the angle formed between the top surface (Vb) of the first element and the front surface (V2) of the second element. As already indicated, it is therefore adjustable between 65 ° and 90 °, preferably between 75 ° and 90 °. It can also be more, such as for example 55 °, although the majority of the Z-stages will have an average Beta angle of 75 °. Here too we see that the points P1 and P2 make contact and lie both in the plane (VI) and in the plane (V2). However, this also does not have to be the case in this case, as will appear in Figs.

Fig. 3b: Detail A of Fig. 3a of the coupling means (K1 and K2) according to the invention. The plane (V2) of the second ^panel is at an angle alpha is rotated further with respect to plane (VI). This type of stair version has a Z-stage. On average, the angle alpha is 15 °. However, this can be different from step to step. Here too we see that the points P1 and P2 make contact and lie both in the plane (VI) and in the plane (V2). However, this also does not have to be the case in this case, as will appear in Figs.

BE2017 / 5750

From the detail it is clearly visible that this further rotation is made possible by means of present air cavities. These air cavities are illustrated in detail in fig.

6b, 7 and 8.

Fig 4a / 4b: Mounting method of 2 panels (1, 2) according to the invention. The assembly of the 2 panels is done in this case by d.mv. a rotational movement (T1). The coupling is created at the time of lip (7) of the second ^coupling part (K2) behind lip 6 of the first coupling part (KI) comes and face (V7) of lip 5 is in contact with surface (V8) of the second ^the coupling part (K2). Ideally, a minimum voltage must be overcome. The tension is absorbed by the flexibility or elasticity of lip (5) of the first coupling means (KI), since this lip (5) is pushed slightly backwards during assembly. Due to the created pressure force of lip 5, points P1 and P2 are pressed against each other in the direction D2, and lip 7 is pressed against lip 6 mainly in the directions D1 and to a lesser extent also in the direction D2. This tension or force can be very little, as a result of which the displacement of lip 5, as indicated in figure 4b, with the naked is also not visible. It is understood that other ways of mounting are possible, provided that a different profile may be provided. For ^example, the element 2 is rotated along the front side in the first element, but it could be within the same application, create a system in which the ^{second, the} element (2) along the rear side of the first element (l) is rotated. This may involve certain advantages, a major disadvantage, however, would then be that, if the first element (1) has already been mounted on the step, the ^{second, the} element can not be mounted. If the ^{second, the} element (2) is to be rotated, this can however still be subsequently mounted along the front side in the first element (l).

FIG. 5a / 5b: Mounting method of 2 panels (1, 2) according to the invention. The assembly of the 2 panels is done in this case by d.mv. a snap movement (T1). The coupling is created at the time of lip (7) of the second ^coupling part (K2) behind lip 6 of the first coupling part (KI) comes and face (V7) of lip 5 is in contact with surface (V8) of the second ^the coupling part (K2). To achieve this, when pushing the coupling part (K2) forward, lip 5 of the coupling part (K1) is pushed backwards (Force F1) to that plane

BE2017 / 5750 (V8) until it reaches plane (V7). In principle when the barbs located on the lip (5) of the coupling part (K1) and on the coupling part (K2) have been overcome. Ideally, lip (5) will always continue to exert a small tension in the mounted state. Due to the created pressure force of lip 5, points P1 and P2 are pressed against each other in the direction D2, and lip 7 is pressed against lip 6 mainly in the directions D1 and to a lesser extent also in the direction D2. This tension or force can be very little, as a result of which the displacement of lip 5, as indicated in figure 4b, with the naked is also not visible.

FIG. 6a / 6b: Detail of the coupling means (K1 and K2) according to the invention. The coupling means (K2) of ^the second panel (2) can be clamped in the coupling agent (KI) of the first panel (1), whereby the first panel and the second ^panel (2) are connected to each other. The first panel (1) and the second ^panel (2) are connected to one another both in the direction (Dl) as well as in the direction (D2). The surface (Vl) of the first panel (1) and the plane (V2) of the second ^panel (2) are substantially parallel. This implementation of stair renovation is known as a straight staircase. This implementation is explained further in this document. On the detail of the clamping parts (K1 and K2) we can see that the points (P1 and P2) make contact with each other. The first clamping part (Kl) has a groove which is bounded at the top by lip (6) and bounded at the bottom by lip (5). It is clearly visible from the detail that the lip (5) protrudes beyond the lip (6). The reason for this is to ensure easy assembly and disassembly. Typical of a connection between the coupling means (K1 and K2) according to the invention is that at least 2 air cavities (L1 and L2) are formed Air cavity (L1) is located just below the contact points P1 and P2. The ^{2, the} air cavity is located between the lip 5 of ^the second coupling part (K2) and the lower side of coupling element (K2). These air cavities (L1 and L2) have 2 functions, ie a first function is to get rid of the dirt, saw and / or profiling residues so that they cannot influence the tolerances and / or prevent assembly. A second reason is that ^the coupling part (K) takes place must be able to provide coupling part (K2), if plane (V2) of ^the second panel (2) is rotated further than plane (Vl), in order to eg. create a Z-stage. The end point or the maximum angle (Alfa Max) is reached if flat (V6) against

BE2017 / 5750 flat (V5). It is understood that this end point can also be achieved differently, so one could also make the end point between plane (V3) and plane (V4).

The end point can in principle be laid anywhere.

Fig. 7: Detail of the coupling means (K1 and K2) according to the invention. The coupling means (K2) of ^the second panel (2) can be clamped in the coupling agent (KI) of the first panel (L) through which the first panel and ^the second panel (2) are connected to each other. The first panel (1) and the second ^panel (2) are connected to one another both in the direction (Dl) as well as in the direction (D2). The plane (VI) of the first panel (l) and the plane (V2) of the second ^panel (2) are not parallel but under an angle Alpha with respect to each other. However, it can be seen that the maximum angle has not yet been reached since the surface (V6) does not yet press against surface (V5). This implementation of stair renovation is known as a Z-stage. On the detail of the clamping parts (K1 and K2) we can see that the points (P1 and P2) make contact with each other. The first clamping part (Kl) has a groove which is bounded at the top by lip (6) and bounded at the bottom by lip (5). It is clearly visible from the detail that the lip (5) protrudes beyond the lip (6). The reason for this is to ensure easy assembly and disassembly. Typical of a connection between the coupling means (K1 and K2) according to the invention is that at least 2 light cavities (L1 and L2) are formed. Air cavity (L1) is located just below the contact points P1 and P2. The ^{2, the} air cavity is located between the lip 5 of the first coupling part (KI), and the lower side of coupling element (K2). These air cavities (L1 and L2) have 2 functions, a first function is to get rid of the dirt, saw and / or profiling residues so that they cannot influence the tolerances and / or prevent assembly. A second ^reason is that coupling part (K) takes place must be able to provide coupling part (K2), if plane (V2) of the second is rotated ^{further, the} panel (2) over face (VI), in order for example to create a Z-stage to be. The end point or the maximum angle (Alfa Max) is reached if flat (V6) presses against flat (V5). It is understood that this end point can also be achieved differently, so one could also make the end point between plane (V3) and plane (V4). The end point can in principle be laid anywhere. On the detail can also be clearly seen that in the execution of the rotation or rotation of the second ^the

BE2017 / 5750 panel (2) with respect to the first panel (1) with points P1 and P2 as center or center point, rub surfaces (V7 / V8) substantially against each other according to a radius (R2) and surfaces (V9 / V10) against each other rub according to radius (R1). The faces (V8, V7) are therefore mainly designed according to a radius (R2), and the faces (V9 / V10) are mainly designed according to radius (R1).

The coupling means (K2) of ^the second panel (2) can be clamped in the coupling means (K) of the first panel (L) through which the first panel and ^the second panel (2) are connected to each other. The first panel (1) and the second ^panel (2) are connected to one another both in the direction (Dl) as well as in the direction (D2). The surface (Vl) of the first panel (1) and the plane (V2) of the second ^panel (2) are not parallel but under an angle Alpha Max with respect to each other. The maximum angle has been reached since the face (V6) presses against face (V5). This implementation of stair renovation is known as a Z-stage. On average this angle is 15 °, but this can be different depending on the desired design. On the detail of the clamping parts (K1 and K2) we can see that the points (P1 and P2) make contact with each other. The first clamping part (Kl) has a groove which is bounded at the top by lip (6) and bounded at the bottom by lip (5). It is clearly visible from the detail that the lip (5) protrudes beyond the lip (6). The reason for this is to ensure easy assembly and disassembly. Typical of a connection between the coupling means (K1 and K2) according to the invention is that at least 2 light cavities (L1 and L2) are formed. Air cavity (L1) is located just below the contact points P1 and P2. The ^{2, the} air cavity is located between the lip 5 of the first coupling part (KI), and the lower side of coupling element (K2). These air cavities (L1 and L2) have 2 functions, a first function is to get rid of the dirt, saw and / or profiling residues so that they cannot influence the tolerances and / or prevent assembly. A second ^reason is that coupling part (K) takes place must be able to provide coupling part (K2), if plane (V2) of the second is rotated ^{further, the} panel (2) over face (VI), in order for example to create a Z-stage to be. The end point or the maximum angle (Alfa Max) is reached if flat (V6) presses against flat (V5). It is understood that this end point also

BE2017 / 5750 can be achieved otherwise, the end point could also be made between plane (V3) and plane (V4). The end point can in principle be laid anywhere. On the detail can also be clearly seen that in the execution of the rotation or rotation of the second ^panel (2) relative to the first panel (I) with the points PI and P2 as the center point or center point, surfaces (V7 / V8) substantially rub against each other according to a radius (R2) and surfaces (V9 / V10) rub against each other according to radius (R1). The faces (V8, V7) are therefore mainly designed according to a radius (R2), and the faces (V9 / V10) are mainly designed according to radius (R1). However, such an embodiment is not necessary.

FIG. 9a: Detail of 2 linked panels (1, 2) for stair renovation. The 2 panels are in coupled condition and points P1 and P2 make contact with each other. The plane (VI) does not lie in the same plane as the plane (V2) of the second ^panel. The contact point P1 is not in the plane V1 of the first panel, but is more to the left of plane V1 of the first panel. In the coupling of the two panels, we see mainly two air cavities, namely a first air cavity (Ll) just below contact points (P1, P2), and a second ^air cavity (L2) at the top lip 5. Since lip 5 are no loose lip, it may contain little absorb voltage or tolerances. To solve this, it is possible to mill a groove behind lip 5, so that it can move more. The plane (VI) is essentially parallel to the plane (V2). In contrast to the previous examples is plane VI thus not in the same plane as the plane V2 of ^the second panel. This indicates that this invention can therefore also be used with another embodiment such as the previously discussed embodiments.

This embodiment can be used when the first panel is for example a solid or neck solid wood panel, or if one wants to create a staircase in which the nose ^{2, the} panel perfectly fits to the underside of the stair nosing.

FIG. 9b: Detail of 2 linked panels (1,2) for stair renovation. The 2 panels are in coupled condition and points P1 and P2 make contact with each other. The plane (VI) does not lie in the same plane as the plane (V2) of the second ^panel. The contact point P1 is not in the plane V1 of the first panel, but is more to the left of plane V1 of the first panel. In the coupling of the 2 panels we mainly see 2 air cavities,

BE2017 / 5750, namely a first air cavity (LI) just below contact points (P1, P2), and a second ^air cavity (L2) at the top lip 5. Since lip 5 is no loose lip can compensate for this low voltage or tolerances. To solve this, it is possible to mill a groove behind lip 5, so that it can move more. The plane (V2) is not parallel to the plane (VI) but is at an angle (Alpha) with respect to the plane (VI). In contrast to the previous examples is plane VI thus not in the same plane as the plane V2 of ^the second panel. This indicates that this invention can therefore also be used with another embodiment such as the previously discussed embodiments. The angle (Beta) is the angle formed between the upper face (Vb) of the first element and the front face (V2) of ^the second element. As already indicated, it is therefore adjustable between 75 ° and 90 °. It can also be more, such as 65 °, although the majority of the Z-stages will have an average Beta angle of 75 °. It is understood that for other designs, this innovation can also be used to form all kinds of different angles between 0 ° and 90 °.

This embodiment can be used if the first panel for example is a solid or semi-solid wood panel, or if one wants to create a staircase in which the nose ^{2, the} panel perfectly fits to the underside of the stair nosing.

The plane (VI) does not lie in the same plane as the plane (V2) of the second ^panel. The contact point Pl is not in the plane V1 of the first panel, but is more to the left of plane V1 of the first panel. In the coupling of the two panels, we see mainly two air cavities, namely a first air cavity (Ll) just below contact points (P1, P2), and a second ^air cavity (L2) at the top lip 5. One has a groove G placed just next to lip 5 making it flexible and able to accommodate more tolerances. The plane (V2) is not parallel to the plane (VI) but is at an angle (Alpha) with respect to the plane (VI). In contrast to the previous examples is plane VI thus not in the same plane as the plane V2 of ^the second panel. This indicates that this invention can therefore also be used with another embodiment such as the previously discussed embodiments. The angle (Beta) is the angle formed between the top surface (Vb) of the first element and the front surface (V2)

BE2017 / 5750 of ^the second element. As already indicated, it is therefore adjustable between 75 ° and 90 °.

It can also be more, such as 65 °, although the majority of the Z-stages will have an average Beta angle of 75 °.

This embodiment can be used if the first panel for example is a solid or semi-solid wood panel, or if one wants to create a staircase in which the nose ^{2, the} panel perfectly fits to the underside of the stair nosing.

The plane (VI) is situated in the same plane as the plane (V2) of the second ^panel. The contact point P1 is not in the plane VI of the first panel, but is more to the left of plane VI of the first panel. The point P2 is also not in the plane V2 of the second ^panel, but also is located more to the left of the plane V2. The transition from the first to the second ^{panel, the} panel is now carried out with a V-groove. As a result, the contact points are no longer in the planes VI and V2, there are more to the left. This V-growth can be finished with a varnish, a paint, a transfer film or can be pressed into the carrier material. Such finishes are already known with laminate floor panels and / or vinyl floor panels. In the coupling of the two panels, we see mainly two air cavities, namely a first air cavity (LI) just below contact points (P1, P2), and a second ^air cavity (L2) at the top lip 5. The plane (VI) is substantially parallel to the flat (V2).

The plane (VI) does not lie in the same plane as the plane (V2) of the second ^panel. The contact point P1 is not in the plane VI of the first panel, but is more to the left of plane VI of the first panel. The point P2 is also not in the plane V2 of the second ^panel, but also is located more to the left of the plane V2.

In the coupling of the panels 2, we mainly see the second air cavities, namely a first air cavity (Ll) just below contact points (P1, P2), and a second ^air cavity (L2)

BE2017 / 5750 above lip 5. The plane (VI) is not parallel to the plane (V2), but the plane (V2) is at an angle (Alfa) with respect to plane (V1).

FIG. 11: 2 panels (1,2) for stair renovation according to the invention. The coupling means (K2) of ^the second panel (2) can be clamped in the coupling means (K) of the first panel (1), whereby the first panel and the second ^panel (2) are connected to each other. The first panel (1) and the second ^panel (2) are connected to one another both in the direction (Dl) as well as in the direction (D2). The plane (VI) of the first panel (l) and the plane (V2) of the second ^panel (2) are substantially parallel. This implementation of stair renovation is known as a straight staircase. The points (P1 and P2) are in the same plane as (VI and V2). The figure shows that the carrier material is made up of 2 different carrier materials (10 'and 10 ”). The carrier material at the bottom (10 ”) is a wood-based board material such as MDF, chipboard, HDF, Multiplex ...

The carrier material at the top (10 ') is a PVC or plastic-like carrier material provided with a decorative top layer (3). Such a material is commercially known as LVT (luxury vinyl tiles) or cushion vinyl.

Such a construction can offer some advantages, namely less noise when walking compared to hard materials such as CPL, HPL or DPL; a ^{2, the} advantage is the water-proof, since the upper top layer (3) and carrier material (lO ') is a water-resistant plastic. It is also the case that with such a construction it is possible to use softer or less qualitative carrier materials at the bottom (10 ") since most forces are absorbed by the upper carrier material (10").

At the first panel (1) we see at the transition (11) from the top surface (Vb) to the vertical side (VI) that a part of the carrier material (10 'and 10' ') has been replaced by a filler with a different composition than the carrier material (10 'and 10' '). In other words, a recess is provided at the level of the transition (11) which is at least partially filled with a filler with a different composition than the carrier material (10 "/ 10"). This is necessary to manufacture the stair renovation profile (1) from a sheet material, as indicated in figures 13a, 13b and 13c. The decorative top layer (3) does, however, continue uninterruptedly over the transition from the top surface (Vb) to the vertical surface (V1) of the first panel / profile (1). At the height

BE2017 / 5750 of transition (11), a thin residual layer of carrier material (10 ') is still present under the decorative top layer (3). The thickness of this residual layer of carrier material (10 ") is practically constant during the curved transition (11). The drawing shows that the filler supports the residual layer of carrier material (10 ') in the transition, this is a major advantage in terms of firmness and compressive force, since one walks on these profiles and thus also on this transition (11). However, this is not always necessary, if the carrier material (10 ') is strong enough, the filler and / or adhesive (36) need not support the transition. However, there will always be a recess at the level of the transition which is at least partially filled with a filling means (36). However, this filler can be present anywhere in the recess.

FIG. 12a: 2 panels (1,2) for stair renovation according to the invention. The coupling part (K2) of the second ^panel (2) can be clamped in the coupling part (KI) of the first stage panel (1) so that the first-stage panel and the 2 ^nd stage panel (2) are connected to each other. The first panel (1) and the second ^panel of the first profile (1) is perpendicular to the top surface (2) are connected to one another both in the direction (Dl) as well as in the direction (D2) .The surface (VI) (Vb) of this first profile (Vb).

The points (P1 and P2) are in the same plane as planes (VI and V2). The figure shows that the carrier material is made up of 2 different carrier materials (10 'and 10 ”). The carrier material at the bottom (10 ”) can be a wood-based plate material such as MDF, chipboard, HDF, Multiplex ..., but can also be another panel such as a plastic plate.

The carrier material at the top (10 ') is a PVC or plastic-like carrier material provided with a decorative top layer (3). Such a material is commercially known as LVT (luxury vinyl tiles) or cushion vinyl.

Such a construction can offer some advantages, namely less noise when walking compared to hard materials such as CPL, HPL or DPL; a ^{2, the} advantage is the water-proof, since the upper top layer (3) and carrier material (lO ') is a water-resistant plastic. It is also true that one can make use of such a structure

BE2017 / 5750 of softer or less qualitative carrier materials at the bottom (10 ") since most forces are absorbed by the upper carrier material (10").

FIG. 12b: Detail A of Fig. 12a of a stair profile according to the invention. At the first panel (1) we see at the transition (11) from the top surface (Vb) to the vertical side (V1) that a part of the carrier material (10 'and 10') has been replaced by a filler with another composition than the carrier material (10 'and 10'). This is necessary to manufacture the stair renovation profile (1) from a sheet material, as indicated in figures f3a, f3b and 13c. The decorative top layer (3) does, however, continue uninterruptedly over the transition from the top surface (Vb) to the vertical surface (V1) of the first panel / profile (1). At the level of transition (11), under the decorative top layer (3), a thin residual layer of carrier material (10 ') is still present. The thickness of this residual layer of carrier material (10 ") is practically constant during the curved transition (11). The drawing shows that the filler supports the residual layer of carrier material (10 ') in the transition, this is a major advantage in terms of firmness and compressive force, since one walks on these profiles and thus also on this transition (11). However, this is not always necessary, if the residual layer of carrier material (10 ') is strong enough, the filler and / or adhesive (36) need not support the transition. However, there will always be a recess at the level of the transition which is at least partially filled with a filling means (36). However, this filler can be present anywhere in the recess. The recess runs from the bottom of the residual layer of carrier material (10 ') at the level of the transition (11) to the bottom of the first stair profile (1).

FIG. 13a: Method of manufacturing the first stair profile (1) according to the invention. A panel-shaped element is supplied. This panel-shaped element is made up of 2 different types of carrier material (10 "and 10"). The first type of carrier material (10 ") can be an LVT-like product with, for example, a thickness of 3 mm or more. LVT (luxury vinyl tiles) is a well-known floor covering material in the market that can vary in structure. For example, an LVT plate material can have different top layers and these plates can also be provided with one or more glass webs

A recess is provided on the rear side (the non-decorative side), resulting in a residual part (11) consisting of a thin residual layer of carrier material (10 ') and the decorative top layer (3).

A clamping part (KI) is provided on a longitudinal end of the supplied panel (1). This clamping part needs to see that it is ^{2, the} panel (2) can be clamped can be inserted.

This filler may be arranged such that it supports the residual layer of carrier material (10 ") at the level of the transition (11), but this is not always necessary.

FIG. 13c 2 Method of manufacturing the first stair profile (1) according to the invention. A panel-shaped element is supplied. This panel-shaped element is made up of 2 different types of carrier material (10 "and 10").

A filler (36) and / or adhesive (36) was provided in the recess. This filler can be arranged such that it supports the residual layer of carrier material (10 ') at the level of the transition (11), but this is not always necessary. The remaining part (11) is folded over until the desired radius is reached. The vertical plane (V1) thus comes to be at an angle with respect to the upper surface (Vb). This angle can be different, in the majority of cases the angle will be 90 °.

FIG. 14a: 2 panels (1, 2) for stair renovation according to the invention. The coupling part (K2) of the second ^panel (2) can be clamped in the coupling part (KI) of the first stage panel (L) through which the first-stage panel and the 2 ^nd stage panel (2) are connected to each other. The first panel (1) and the second ^panel (2) are connected to one another both in the direction (Dl) as well as in the direction (D2) .The surface (VI) of the first profile (1) is substantially perpendicular to the top surface (Vb) of this first profile (Vb). The surface (Vl) of the first panel (l) and the plane (V2) of the second ^panel (2) are substantially parallel. This implementation of stair renovation is known as a straight staircase. The points (P1 and P2) are in the same plane as planes (VI and V2). The figure shows that the carrier material is made up of 2 different carrier materials (10 'and 10 ”). The carrier material at the bottom (10 ”) can be a wood-based board material such as MDF, chipboard, HDF, Munltiplex, etc., but can also be another panel such as a plastic board.

The carrier material at the top (10 ') is a PVC or plastic-like carrier material provided with a decorative top layer (3). Such a material is commercially known as LVT (luxury vinyl tiles) or cushion vinyl.

Such a construction can offer some advantages, namely less noise when walking compared to hard materials such as CPL, HPL or DPL; a ^{2, the} advantage is the

BE2017 / 5750 waterproof, since the upper top layer (3) and carrier material (10 ") is a waterproof plastic. It is also the case that with such a construction one can use softer or less qualitative carrier materials at the bottom (10 ") since most forces are absorbed by the upper carrier material (10").

FIG. 14b: Detail A of Fig. 14a of a stair profile according to the invention. At the first panel (1) we see at the transition (11) from the top surface (Vb) to the vertical side (V1) that a part of the carrier material (10 'and 10' ') has been replaced by a filler with a composition other than the carrier material (10 'and 10' '). This is necessary to manufacture the stair renovation profile (1) from a plate material, as indicated in figures 13a, 13b and 13c. The decorative top layer (3) does, however, continue uninterruptedly over the transition from the top surface (Vb) to the vertical surface (VI) of the first panel / profile (1). At the level of transition (11), under the decorative top layer (3), a thin residual layer of carrier material (10 ') is still present. Unlike on figures 11 and 12, the remaining part is now not a plane, but a point. This creates a smaller radius at the transition. The drawing shows that the filler supports the residual layer of carrier material (10 ") in the transition, this is a great advantage in terms of firmness and compressive force, since one walks on these profiles and thus also on this transition (11). However, this is not always necessary, if the residual layer of carrier material (10 ') is strong enough, the filler and / or adhesive (36) need not support the transition. However, there will always be a recess at the level of the transition which is at least partially filled with a filling means (36). However, this filler can be present anywhere in the recess. The recess runs from the bottom of the residual layer of carrier material (10 ') at the level of the transition (11) to the bottom of the first stair profile (1).

Fi2. 15: The first stair profile (1) according to the invention. This stair profile (1) is made up of 2 different types of carrier material (10 "and 10"). The first type of carrier material (10 ") can be an LVT-like product with, for example, a thickness of 3 mm or more. LVT (luxury vinyl tiles) is a well-known floor covering material in the market

BE2017 / 5750 can be different in structure. For example, an LVT plate material can have different top layers and these plates can also be provided with one or more glass webs or other stabilizers to reinforce and / or stabilize the product. The 2 ^the carrier material (10 ') may be a sheet material based on wood, such as an MDF, an LPF, a chipboard or a plywood ...

A filler (36) and / or adhesive (36) was provided in the recess. This filler can be arranged such that it supports the residual layer of carrier material (10 ') at the level of the transition (11), but this is not always necessary. The remaining part (11) was folded over until the desired radius was reached. The vertical surface (VI) thus comes to be at an angle with respect to the upper surface (Vb). This angle can be different, in the majority of cases the angle will be 90 °.

A clamping part (K3 and KI) is provided at both along the ends of the profile. This means that you can continue to build on both sides. This profile can be useful on the top step, where you have to connect to the rest of the floor covering of this floor.

FIG. 16a: An example of how the layer-shaped material can be pleated to produce a stair profile according to the invention. In comparison with the previously discussed profiles, the transition (11) has a minimal radius. This is achieved by milling the recess in the carrier material into a point shape. However, this is not ideal and in many cases will result in strong tensile stresses in the residual layer of carrier material (10 ') and the coating layer (3) in the transition (11). If this carrier material (10') has one or more layers, for example Glass fibers (V ), this tensile stress Ft will manifest itself in strong shear stress Fs at the level of this glass fiber (v), so that there is a good chance that this carrier material will tear at the level of the glass fiber.

FIG. 16b: A solution to the problem discussed above is to mill the transition, instead of at a point, into a plane with a certain width b, thereby creating a residual part (11) made up of a residual layer of carrier material (10 ') and the decorative

BE2017 / 5750 top layer (3). This surface or residual part (11) will, when it is closed, form itself into e.g. 90 ° in such a way that the transition is voltage-free.

FIG. 16c: Plate material that consists of different layers of carrier material (10 ", 10"). In this case, the support material 1 "located just below the coating layer (2) is thermoplastic and has a glass fiber (V) in the core parallel to the coating layer (2). This is a structure of an LVT floor slab. It is generally assumed that the bond between the glass fleece (V) and the thermoplastic carrier material (1 ") is less. Because the milling takes place at a point, large shear forces (Fs) arise at the core of the LVT slab at the level of the glass fleece or glass fiber (V), as a result of which the LVT material will split at the level of the glass fleece. To solve this, one must perform the profiling as described in Figure 12b. It is also the case that if the filler (36) also acts as an adhesive and the adhesive with the carrier material both above (1 ') and below the glass fleece (1') the stress (Fs) in the glass fleece is completely eliminated, so that the chance that this split will be completely removed.

FIG. 17a: Detail of the transition from the top surface (Vb) to the vertical surface (V1) of the first stair profile (1) according to the invention. The detail shows where the filler is present at the level of the transition (11). Below the residual layer of carrier material (1) there is an air cavity that is partially filled with a filler or adhesive (36). The residual layer of carrier material (1) is not supported by the filler (36), but the filler or adhesive (36) makes that the shape of the remainder and therefore of the transition (11) remains good.

In many cases, such as with thermoplastic carrier materials, it may be that the residual layer of carrier material (1) is still thick enough so that it is not compressible.

A glass fleece (V) is located in the middle of the layer of thermoplastic carrier material (1). The drawing shows that the adhesive (36) is located both above and below the glass fiber (V). As a result, no tensile and / or shear stresses can arise in, under or above the glass fiber (V).

BE2017 / 5750

FIG. 17b: Detail of the transition from the top surface (Vb) to the vertical surface (VI) of the first stair profile (1) according to the invention. The detail shows where the filler means (36) is present at the level of the transition (11). Below the residual layer of carrier material (10 ") there is an air cavity that is partially filled with a filler or adhesive (36). The residual layer of carrier material (10 ') is not supported by the filler (36), but the filler or adhesive (36) does ensure that the shape of the residual part and therefore of the transition (11) remains good. The filler (36) is at least partially, if not completely, transverse to the layer direction of the carrier material (10 "). This results in a very strong connection so that it will not break or be damaged in the event of forces and / or sawing.

FIG. 18a: Example of an embodiment of a stair covering according to the invention. The ^{2, the} panel (2) is perpendicular to the upper face (Vb) of the first panel (L). This version is known as a straight staircase. Because the panels (1,2) are coupled to each other over the entire width by means of a clamp coupling, both panels connect very well, even though there is a curvature on one or both panels (1,2).

FIG. 18b: Side view of 2 stair profiles (1 and 2) according to the invention. The 2 panels are coupled to each other and the front surface (V2) is almost vertical to the top surface (Vb). This coupling is necessary for obtaining a straight staircase.

BE2017 / 5750

FIG. 19b: Side view of 2 stair profiles (1 and 2) according to the invention. The two panels are coupled to each other, and the front face (V2) of the second ^panel (2) is a further angle (alpha) is rotated further with respect to perpendicular to the plane (Vb). This coupling is necessary for obtaining a Z stage.

FIG. 20a: Example of an embodiment of a stair covering according to the invention. The ^{2, the} panel (2) is perpendicular to the upper face (Vb) of the first panel (l), however, it is ^{2, the} panel includes a short panel. There is yet a third ^{of the} panel (60) behind this brief 2 ^{of the} panel. This results in a version that is known as a stair nose. Because the panels (1,2) are coupled to each other over the entire width by means of a clamp coupling, both panels connect very well, even though there is a curvature on one or both panels (1,2).

FIG. 20b: Side view of 3 stair profiles (1, 2 and 60) according to the invention.

There is yet a third ^{of the} panel (60) behind this brief 2 ^{of the} panel. This results in a version that is known as a stair nose. Because the panels (1,2) are coupled to each other over the entire width by means of a clamp coupling, both panels connect very well, even though there is a curvature on one or both panels (1,2).

Fig. 21a: 2 panels (1, 2) for stair renovation according to the invention. The figure shows that the carrier material is made up of 2 different carrier materials (10 "and 10"). The carrier material at the bottom (10 ”) is a wood-based board material such as MDF, chipboard, HDF, plywood ...

The carrier material at the top (10 ') is a PVC or plastic-like carrier material provided with a decorative top layer (3). Such a material is commercially known as LVT (luxury vinyl tiles) or cushion vinyl.

One side of the first profile (1) is provided with a clamping system (Kl) on the underside as already described in this document. The opposite side is provided with a nose part (N) which is also provided, both in front and

BE2017 / 5750 at the bottom, of a decorative top layer (3). The advantage of such a stair profile (1) is that it can be used for 4 stair versions; Nl. A straight stair (Figure 21b), a Z stair (Figure 21c), a straight stair with stair nose (Figure 21d) and a Z stair with stair nose (Figure 21e). To make this possible, the first stair profile (1) must be adjusted by either sawing off the nose part (N) (21b, 21c) or by sawing off the part with the clamping part (Kl) (21d, 21 ej. An example of the place of the saw is represented in the figures (2f b, c, d, e) by means of the letter C.

FIG. 22a: Panel (1) for stair renovation according to the invention. The figure shows that the carrier material is made up of 2 different carrier materials (10 "and 10"). The carrier material at the bottom (10 ”) is a wood-based board material such as MDF, chipboard, HDF, Multiplex ...

The carrier material at the top (10 ') is a PVC or plastic-like carrier material provided with a decorative top layer (3). Such a material is commercially known as LVT (luxury vinyl tiles) or cushion vinyl. It is clear that the parent support material (10 ") can be any material.

One side of the first profile (1) is provided with a clamping system (Kl) on the underside as already described in this document. The opposite side is provided with a nose part (N) which is also provided, both at the front and at the bottom, with a decorative top layer (3). The advantage of such a stair profile (1) is that it can be used for 4 stair versions; Nl. A straight stair (Figure 21b), a Z stair (Figure 21c), a straight stair with stair nose (Figure 21d) and a Z stair with stair nose (Figure 21e). To make this possible, the first stair profile (1) must be adjusted by either cutting the nose part (N) or cutting it off (21b, 21c) or by cutting the part with the clamping part (Kl) (21d, 21st).

A groove (G) is provided next to the nose part (N). This offers the possibility of simply cutting the nose part (N) with a cutter. The groove (G) is provided along the rear side of the profile (1) and runs a large part, if not all the way through the lower support material (10 "). The plastic-like carrier material (10 ') usually cuts very simply, simpler than the wood-based carrier material

BE2017 / 5750 (10 "). It is clear that the groove (G) does not have to run all the way through the lower carrier material (10 "). The advantage of the nose part (N) that can easily be cut off with a cutter is that this nose part (N) can be used virtually undamaged, e.g. to finish the back of an open staircase. It is clear that several grooves (G) can occur in order to simplify the abbreviation or adjustment of the renovation profile (1).

FIG. 22b and Fig. 22c indicate how cutting the stair nose by means of a cutter or saw must be done.

Fig 23a / 23b: Stair renovation system according to the invention. 2 panels (1,2) are shown on the image. The 2 profiles (1,2) have a support material (10) on which a decorative top layer (3) is applied. This decorative top layer (3) can be constructed from a decorative layer with a scratch-resistant top layer on top or can be a decorative layer that is already sufficiently scratch-resistant. These top layers have been known for a long time and can be paper foils, a plastic film (PVC, PP, pet ...), a CPL, an HPL, an LVT, a vinyl, veneer, wood ... etc. These decorative top layers (3) can be provided with a specific decor such as a wood imitation, a stone imitation or the like. It is clear that the decorative top layer (3) does not necessarily have to be scratch-resistant. Thus, after mounting, the profiles can also be provided with a lacquer or an oil that makes the whole sufficiently scratch-resistant. It is also clear that according to the invention the decorative top layer (3) is not necessary. For example, it may be that the finishing layer is applied to it after the fitting of stair profiles. Just think of covering vinyl or carpet on the stair profiles. The rear of the panels or profiles (1,2) can be provided with a backing (4) (foil on the back), but this is also not necessary in many cases. The carrier material (10) can be of a different nature, for example, these profiles can be composed of a PVC, a plastic, an MDF, an LDF, an HDF, chipboard or another wood-based plate material or solid wood. The profiles can be manufactured by extrusion or by means of profiling a sheet material as discussed further later in this document.

BE2017 / 5750

The first profile (1) consists essentially of a horizontal section which continues downwards on the right-hand side to a shorter vertical section. The horizontal portion of the first stair profile (1) has an upper surface (Vb). This top surface is essentially horizontal after mounting and will be considered in this document as a reference surface to define certain angles. The longitudinal end of said relatively short vertical portion is provided with a coupling part (KI), which serves to be clamped to be included in the 2 ^{to the} panel (2). It is clear that other versions of this first profile (1) are possible. The coupling part (K1) can thus be provided directly in the horizontal part without a short vertical part being present. The vertical part may in certain cases be indicated in terms of aesthetics and / or strength of the stair profile.

The short vertical part of the first panel (1) contains a plane V1 that ends in point Pl. We can easily state that the coupling part (Kl) is located at the bottom of the first panel (1) or profile. It is also the case that not every version will have a vertical surface (VI), so the transition from the horizontal top surface (Vb) to the point (P1) can be an arc.

The ^{2, the} profile (2) is substantially constructed vertically with respect to the top face (Vb) of the first panel (L). The upper side of the vertical part (2) comprises a coupling part (K2) in which the first coupling part (K1) of the first panel (1) can be clampably received. The carrier material (lO) of the second ^panel (2) may have the same structure as the carrier material (lO) of the l ^th panel, but can also be different, as well as the decorative top layer (3) of the second ^panel (2) . The 2 coupling parts (K1, K2) are designed or designed in such a way that the 2 panels or profiles (1, 2) can be clampably coupled in such a way that the surface (VI) of the first panel (1) and the surface (V2) of the second ^panel (2) in the coupled state, run parallel to each other and in that the two points (Pl and P2) substantially make contact with each other. It is also the case that the plane (VI) is perpendicular to the upper plane (Vb). The ^{2, the} panel (2), one can, depending on the desired implementation of the staircase renovation, continue turning or rotating with contact points (Pl and P2) as the center point is reached until the desired angle between the two planes (Vb, and V2). Both in the coupled state where the planes (Vb and V2) are perpendicular as well as in the coupled state in which the plane (V2)

BE2017 / 5750 at an angle (90 ° - alpha) with respect to the plane (Vb), the points (P1 and P2) are intended to make contact. This implementation is explained further in the document. It is understood that tolerances may occur which may result in a minimal play between the 2 contact points (P1 and P2), but this has very little effect on the aesthetic of the end result and thus does not detract from the innovative and innovative character. of this invention.

Fig 24a / 24b: Stair renovation system according to the invention. 2 panels (1,2) are shown on the image. The 2 profiles (1, 2) have a support material (10) on which a decorative top layer (3) is applied. This decorative top layer (3) can be constructed from a decorative layer with a scratch-resistant top layer on top or can be a decorative layer that is already sufficiently scratch-resistant. These top layers have been known for a long time and can be paper foils, a plastic film (PVC, PP, pet ...), a CPL, an HPL, an LVT, a vinyl, veneer, wood ... etc. These decorative top layers (3) can be provided with a specific decor such as a wood imitation, a stone imitation or the like. It is clear that the decorative top layer (3) does not necessarily have to be scratch-resistant. Thus, after mounting, the profiles can also be provided with a lacquer or an oil that makes the whole sufficiently scratch-resistant. It is also clear that according to the invention the decorative top layer (3) is not necessary. For example, it may be that the finishing layer is applied to it after mounting stair profiles. Just think of covering vinyl or carpet on the stair profiles. The rear of the panels or profiles (1,2) can be provided with a backing (4) (foil on the back), but this is also not necessary in many cases. The carrier material (10) can be of a different nature, for example, these profiles can be composed of a PVC, a plastic, an MDF, an LDF, an HDF, chipboard or another wood-based plate material or solid wood. The profiles can be manufactured by means of extrusion or by profiling a sheet material as discussed further later in this document.

The first profile (1) consists essentially of a horizontal section which continues downwards on the right-hand side to a shorter vertical section. The horizontal portion of the first stair profile (1) has an upper surface (Vb). This

BE2017 / 5750 top surface after mounting is mainly horizontal and will be considered in this document as a reference surface to define certain angles. The longitudinal end of said relatively short vertical portion is provided with a coupling part (K) which serves to be clamped to be included in the 2 ^{to the} panel (2). It is clear that other versions of this first profile (1) are possible. The coupling part (K1) can thus be provided directly in the horizontal part without a short vertical part being present. The vertical part may in certain cases be indicated in terms of aesthetics and / or strength of the stair profile.

The short vertical part of the first panel (1) contains a plane VI that ends in point P1. We can easily state that the coupling part (Kl) is located at the bottom of the first panel (1) or profile. It is also the case that not every version will have a vertical surface (VI), so the transition from the horizontal top surface (Vb) to the point (P1) can be an arc.

The ^{2, the} profile (2) is substantially constructed vertically with respect to the top face (Vb) of the first panel (L). The upper side of the vertical part (2) comprises a coupling part (K2) in which the first coupling part (K1) of the first panel (1) can be clampably received. The carrier material (lO) of the second ^panel (2) may have the same structure as the carrier material (lO) of the l ^th panel, but can also be different, as well as the decorative top layer (3) of the second ^panel (2) . The 2 coupling parts (K1, K2) are designed or designed in such a way that the 2 panels or profiles (1, 2) can be clampably coupled in such a way that the surface (V1) of the first panel (1) and the surface (V2) of the second ^panel (2) in the coupled state, run parallel to each other and in that the two points (Pl and P2) substantially make contact with each other. It is also the case that the plane (VI) is perpendicular to the upper plane (Vb). The ^{2, the} panel (2), one can, depending on the desired implementation of the staircase renovation, continue turning or rotating with contact points (Pl and P2) as the center point is reached until the desired angle between the two planes (Vb, and V2). Both in the coupled state where the faces (Vb and V2) are perpendicular as well as in the coupled state where the face (V2) is at an angle (90 ° - alpha) with respect to the upper face (Vb), the points ( P1 and P2) mainly make contact. In this figure, (24a / 24b), it can be seen that the front side (V 2) of the second ^panel (2), an angle (Alpha) is further rotated than perpendicular

BE2017 / 5750 on the top surface (Vb) of the first panel (1). The ^{2, the} panel (2) is thus at an angle (90 ° -alpha) with respect to the upper face (Vb) of the first panel (L). It is understood that tolerances may occur which may result in a minimal play between the 2 contact points (P1 and P2), but this has very little effect on the aesthetic of the end result and thus does not affect the innovative and innovative nature of this invention.

FIG. 25a / b / c: Stair renovation system according to the invention. Coupling elements K1 and K2 are shown in the figure. It can be seen from the drawing that the tooth (7) is slightly longer than in the previous drawings. This can offer a big advantage for the assembly of the first panel to ^the second panel or vice versa. Preferably the apex (7) passes beyond the point (P2). A chamfer (50) is also provided at the end of the flexible lip of the groove side (K1). This chamfer serves as a guide so that the tooth side (K2) can easily find its way into the groove side (Kl) during assembly.

Especially with curved panels, the improvements discussed above can help to achieve a simple assembly.

It is also true that the desire of the tooth (7) can possibly contribute to a better anchoring of the tooth side (K2) in the groove side (K1).
