Description

Title: Floor finishing profile Description

[0001] This description refers to floor finishing strips or floor finishing profiles that finish off a floor.

[0002] Floor trims are well known. For aesthetic and functional reasons, floor trims are often desired that protrude only slightly or not at all above the floor covering.

[0003] The floor trim strips should also be easy and quick to install, although the gap between the floor covering and the wall can vary greatly.

[0004] There are known finishing strips that can be clamped between the floor covering and the wall. However, existing arrangements do not provide a secure fit when the distance between the floor and the wall varies.

[0005] There is therefore a need for improved floor finishing strips. Summary of the invention

[0006] The present description proposes a floor finishing profile or a profile strip for a floor finish according to independent claim 1.

[0007] In one aspect, the profile strip comprises a cover section, a wall section, and a clamping section. The cover section is arranged in the upper region of the wall section, and the clamping section is arranged at a lower section of the wall section. The clamping section has a first clamping lip and at least one second clamping lip, wherein the first clamping lip and the second clamping lip have different lengths.

[0008] Advantageous embodiments are specified in the dependent claims. Character description

[0009] The invention will become clearer upon reading the following description, which is made with reference to the figures, which show: Figure la is a side view of a floor trim strip; Figure lb shows a cross-section through an alternative floor finishing strip; and Figures 2a to c show side views of a floor finishing strip corresponding to the cross section with different distances between floor and wall. Detailed description

[0010] In the following detailed description of the invention, examples are provided that illustrate aspects and implementations of the invention merely by way of example and are not limiting. It is not necessary to employ all of the features presented with reference to one or more examples to practice the invention. Rather, one skilled in the art will recognize that various features may be omitted or replaced with others without departing from the invention.

[0011] The terms "top," "above," "bottom," and "below" are used here in reference to the intended installation position. Likewise, the terms "wall-side" and "floor-side" refer to the orientation in the intended installation position for the profile, unless explicitly stated otherwise.

[0012] The present disclosure describes a floor finishing strip for placement between a floor structure and a wall. The floor finishing strip is a profile strip designed to be clamped into an edge joint as a gap between the floor structure and the wall. The profile strip can also be referred to as a floor finishing profile. The floor finishing profile can be made in any desired Lengths are provided. The following description refers primarily to the cross-section of the profile and the arrangement of the profile in the edge joint. For simplicity, the edge joint is also referred to as the joint below.

[0013] The floor structure can be a wooden floor, a parquet floor, a plastic floor, a tiled floor, or any other solid floor. The floor can have a single-layer or multi-layer structure, which can be laid and installed in the usual way. During installation, a joint of approximately 10 mm wide remains between the wall and the floor edge; 3 mm to 7 mm is typical. The largest possible tolerance should be allowed for this joint to enable quick and easy installation of the floor structure. The joint can be just a few millimeters wide or significantly more than 10 mm. Depending on the construction method, the joint width can also vary greatly along the same wall. In addition, the joint should compensate for different expansions due to changes in humidity and / or temperature.

[0014] To conceal the remaining joint and simultaneously allow for expansion and contraction of the floor, a skirting board is often installed above the joint to conceal it. However, there is a desire for the floor to be as level as possible. Flexible skirting boards and profiles can be clamped into the joint between the wall and floor. Such floor finishing boards can also be additionally secured in the joint using adhesive, screws, or other fastening methods. However, the use of any fastening method requires additional material and / or labor during installation. Clamping without additional fastening methods is therefore preferred.

[0015] The present disclosure describes a profile strip for a floor wall finish, also referred to as a floor finish strip or floor finish profile. The profile strip comprises a cover section, a wall section, and a clamping section, wherein the cover section is arranged in the upper region of the wall section and wherein the clamping section is arranged at a lower section of the wall section. The cover section serves to close the joint between the wall and floor. The wall section is designed to be arranged on the wall side and to support the profile strips on the wall. The The clamping section creates a clamping or clamping force of the profile between the floor and the wall. The clamping section can be elastically deformable for this purpose. The clamping section has a first clamping lip and at least one second clamping lip.

[0016] The first and second clamping lips are of different lengths. This allows the clamping lips to provide secure clamping across a wider range of joint widths. While the longer of the two clamping lips provides locking for larger joint widths, the shorter of the two clamping lips provides locking for narrower joint widths. This allows the clamping lip best suited to the specific joint width being identified to provide secure locking. A significantly wider range of joint widths can be securely covered, and larger fluctuations, e.g., due to unevenness, can be compensated for. The other clamping lip can provide support in this process.

[0017] In particular, the first clamping lip can be arranged below the second clamping lip, wherein the first clamping lip is shorter than the second clamping lip.

[0018] In one example of the profile strip, the first clamping lip and the second clamping lip can have substantially the same thickness. The same thickness can include the same thickness and / or the same elasticity, or a combination thereof. This simplifies manufacturing.

[0019] The distal, bottom-facing ends of the first and / or second clamping lips can be tapered, for example, upwards. In the installed, bent state, this can provide a contact surface for engagement with the edge or end of the base.

[0020] In one example, the first clamping lip and the second clamping lip can be essentially straight, i.e., uncurved, in the resting state. The resting state is the state before installation. However, it can also be provided that the first and / or second clamping lip is curved or pre-bent to better adjust the clamping tension.

[0021] In one example, the first clamping lip and the second clamping lip may be arranged at an angle to each other that is greater than 2° and less than 35°.

[0022] In one example, an angle between the first clamping lip and the wall portion may be greater than an angle between the second clamping lip and the wall portion.

[0023] In one example, the wall section may have a greater material thickness than at least one of the first clamping lip and the second clamping lip. This achieves greater strength of the profile strip, while the clamping lips remain sufficiently flexible and deformable.

[0024] In another example, the wall section can have at least one wall support elevation on the wall side. The wall support elevation can be designed as a friction nub and / or friction groove. The wall support elevation is designed to increase friction against the wall and prevent the profile strip from rubbing against the wall.

[0025] In another example, the profile strip may include a wall-facing nose, wherein the wall-facing nose is flexible. The wall-facing nose is designed to rest against the wall. The flexible wall-facing nose can conform to the wall and compensate for irregularities in the wall.

[0026] Examples of the invention are described below with reference to the accompanying figures. Figure 1a shows an example of a profile strip which is designed for arrangement in a joint between a floor and a wall. The profile strip can also be referred to as a floor finishing strip. The floor finishing strip can be used instead of a skirting board or underneath a skirting board. The profile strip has a cover section 10, a wall section 20 and a clamping section. In the example shown, the cover section 10, the wall section 20 and the clamping section are formed from the same material in one piece. However, it is also possible to form the profile strip from a mix of materials or from several elements joined together.

[0027] The material of the profile strip is elastic. The material can be rubber or a rubber compound. If rubber is used, a hardness of 50–70 Shore has proven to be good. However, the hardness can be adjusted or varied by a specialist depending on the material, thickness, and structure.

[0028] The wall section 20 is designed to be inserted into the joint between the wall and the floor structure, with the wall section running essentially parallel to the wall. The wall section 20 is designed to be inserted deep into the joint and has a height that can be adjusted to the height of the floor structure. Typically, the height is in the range of 3 mm to 20 mm. The profile is flexible in the longitudinal direction so that the profile can adapt to irregularities along the wall and installation is easier. The profile is less deformable in depth and height. For this purpose, a material thickness of the wall section of approximately 0.5 mm to 10 mm has proven to be effective. This makes the floor finishing strip easy to roll for transport.

[0029] The cover section 10 is connected to the wall section 20 at an upper section or in the upper region thereof or merges into the latter. The cover section 10 covers the joint between the wall and the floor surface and has an upper cover surface 11, which remains visible in many applications. It can therefore be provided to provide the cover surface with a decorative layer, a film or a coating, or to design or color it in a desired color. The cover section 10 can also have a wall nose 12. The wall nose 12 can be flexible and adapt to the shape of the wall so that the wall nose 12 rests against the wall over the entire length of the profile. Unevenness and irregularities in the wall profile can thus be easily compensated for.The covering section 10 can be as thin as possible, providing sufficient stability while also adding as little bulk as possible to provide an unobtrusive and even finish to the floor. Examples of material thicknesses range from 0.5 to 10 mm. The thickness can be constant across the entire width or taper toward the floor side.

[0030] The cover section 10 has a width from the wall side to the floor that is sufficient to completely cover the joint. It is advantageous if the cover section 10 has a larger width and covers the floor by a few millimeters. This ensures a good seal. A support on the floor also supports the locking of the profile in the joint. Advantageous widths are in the range from 5 mm to 30 mm. However, the width can also be adjusted depending on design requirements and joint width tolerance.

[0031] The cover section 10 can remain as a visible finish. It is also possible to provide fastening devices for skirting boards, decorative elements, or other items on the cover section 10. This allows additional elements to be easily attached to the profile strip.

[0032] In the example shown, the clamping section is located on the underside of the wall section 20. The clamping section can also be located higher on the wall section 20. In the example shown, the clamping section comprises a lower clamping lip 32 and a second, upper clamping lip 34. In principle, additional clamping lips can also be provided.

[0033] The clamping lips are designed to clamp into the joint between the wall and the floor structure in order to hold the profile in place. The clamping lips 32, 34 can be bent along their width from the wall side to the floor side. The necessary flexibility is achieved in the example shown by a lower material thickness on the clamping lips. For example, the material thickness of the clamping lips 32, 34 can be less than half the thickness of the wall section 20. The material thickness of the clamping lips 32, 34 can be in the range of a few millimeters, for example in the range of 0.4 to 5 mm. The material thickness of the first clamping lip 32 and the second clamping lip can be selected to be the same. In another example, the material thickness of the first clamping lip 32 and the second clamping lip can also be selected to be different in order to adapt the clamping force.Alternatively or in addition to adjusting the material thickness, the material hardness and / or material composition can also be adjusted. The inventors have discovered that two clamping lips positioned in the lower area of ​​the profile ensure significantly better locking of the profile in the joint.

[0034] The first, lower clamping lip 32 has a smaller width between the wall section and the floor side than the second, upper clamping lip 34. The different widths allow for better adaptation and clamping in different joint widths. This makes the profile more flexible in use. Clamping is maintained over a wide joint range, allowing for higher tolerances and compensation for larger irregularities in the wall profile. The width of the lower clamping lip 32 can be 50 to 80% of the width of the upper clamping lip 34. For example, the lower lip can have a width of 3 to 7 mm from the wall side to the floor side, and the upper clamping lip 34 can have a width of 5 to 10 mm.

[0035] When the profile is inserted into the joint, the upper clamping lip 34 and, depending on the width of the joint, the lower clamping lip 32 deform. The clamping lips are bent upwards due to the friction against the floor structure. This upward bending counteracts any upward movement of the profile and contributes to secure locking in the joint. When the profile moves upwards, the respective clamping lip cannot deform but is compressed, which counteracts the movement. By using two clamping lips of different widths, this effect is ensured over a wide joint area. The upper, wider clamping lip 34 clamps in wider joints or joint areas for which the lower clamping lip 32 is not wide enough. In contrast, the lower clamping lip 32 can ensure the clamping function in narrower joints or joint areas in which the wider upper clamping lip is already bent or curved too far.The interaction of both clamping lips results in an expanded area of ​​application and more reliable clamping in the joint.

[0036] The above-mentioned clamping effect is promoted when the lower clamping lip 32 and upper clamping lip 34 do not meet the floor structure perpendicularly, but at an angle of less than 90°. For this purpose, it is advantageous if the clamping lips are arranged at an angle of less than 90° to the wall section 20 over significant sections of their width. It is advantageous if 50% or more, better 65% or more of the width is at an angle of less than 90° to the wall section 20. This further increases the range of usable joint widths. The angle which the lower clamping lip 32 and / or the upper clamping lip 34 enclose with the wall section 20 can be in the range of 70° to 89°. In an example not shown, the lower clamping lip 32 and / or the upper clamping lip 34 can be arranged at an angle of 90° to the wall section and have an upward curvature.

[0037] It can also be provided that the lower clamping lip 32 and the upper clamping lip have a different angle to the wall section 20. In particular, as in the example shown, the angle between the wall section and the lower clamping lip 32 can be greater than the angle between the wall section 20 and the upper clamping lip 34. The angle between the wall section 20 and the lower clamping lip 32 can be in the range of 80 to 89°, and the angle between the wall section 20 and the upper clamping lip 34 can be in the range of 70° to 85°.

[0038] In another example, the lower clamping lip may also be arranged at an angle of 90° to the wall section and only the upper clamping lip is arranged at an angle of less than 90° to the wall section.

[0039] In other words, the widths of the lower clamping lip 32 and the upper clamping lip 34 are not parallel, but at an angle to each other. An angle between the lower clamping lip 32 and the upper clamping lip 34 in the range of 4° to 15° has proven effective. The lower and upper clamping lips 34 spread out toward the floor side.

[0040] The floor-side ends of the clamping lips 32, 34 can be specially shaped for this purpose, for example, with a bevel or tapered section on the underside. The clamping lips can taper in a wedge shape. This further facilitates locking or wedging into the floor structure.

[0041] It is obvious to a person skilled in the art that further clamping lips can be provided in addition to the two clamping lips shown.

[0042] In the mounted state, inserted between the wall and the floor structure, the clamping lips 32, 34 exert a force between the floor and the wall. The profile is pressed against the wall in the lower area. To prevent the profile from turning out, the profile can provide devices on the wall side that prevent the profile from moving towards and / or along the wall. The profile of the present disclosure can have wall support elevations for this purpose, via which the profile is supported on the wall. In these areas, the friction can be increased, in the simplest case due to the reduced contact surface. In the example shown, the Wall section 20 has a plurality of superimposed grooves 22 that run along the length of the profile. These grooves 22 rest against the wall over long distances and counteract any upward movement of the profile.

[0043] In the example shown, the grooves 22 are distributed across the entire side of the wall section 20, but they can also be provided only in specific locations, for example, in the lower area. Continuous grooves are comparatively inexpensive and simple to manufacture, but other geometric shapes can also be chosen. It is also possible for the grooves to be interrupted rather than continuous in the longitudinal direction and / or to be offset from one another.

[0044] Figure 1b shows a variant of the profile of Figure 1a in cross-section, in which some features have been changed compared to the example in Figure 1a. Compared to the floor finishing strip 2 of Figure 1a, the wall section 120 of the floor finishing strip 102 of Figure 1b has a greater wall thickness. This makes the wall section 20 and thus the floor finishing strip 102 stiffer, resulting in greater mechanical stability in use. However, the material is less easy to roll and transport. In the example shown, the material thickness at the lower clamping strip connection 123, i.e. at the connection between wall section 120 and the lower clamping section 132, is optionally less than the thickness of the wall section 120. This allows the elastic deformability of the lower clamping lip 132 to be influenced and adjusted.

[0045] Alternatively or additionally, the cover section 110 is arranged at an angle of less than 90°, for example, between 85° and 89°, to the wall section 120. This allows a tighter seal to be achieved, for example, with wavy or uneven floor coverings, since the tip section 113 first touches the floor covering when inserted into the joint and seals it.

[0046] Alternatively or in addition to the angle, the radius at the transition between deck section 110 and wall section 120 can be chosen to be larger. This can also achieve greater rigidity. This can be done independently or in combination with the increased wall thickness of wall section 120.

[0047] Only the essential changes compared to the example in Figure 1a are described here. Unless described or illustrated, other features are the same or similar to the above-mentioned example. It will be obvious to a person skilled in the art that further adaptations and modifications can be made in addition to the examples illustrated and described.

[0048] Figures 2a to 2c show the floor finishing strip 2 of Figure 1a in the installed state between a wall 400 and a floor structure 301, 302, 303. Figures 2a, 2b, and 2c differ in that the distance of the floor finishing strip 331, 332, 333 from the wall is different and thus the joint width bl, b2, b3 is different.

[0049] The floor structure 301, 302, 303 is shown only schematically, as the structure of the floor 301, 302, 303 is not important and the floor trim strip can be used with various floor structures. The floor structure 301, 302, 303 can consist of one or more layers and / or elements and have different heights. This is not shown here. It is also clear that the depth of the joint is not important, and the floor trim strip described here can be used with floor structures of different heights.

[0050] In Figure 2a, the distance bl between the lateral floor finish 331 of the floor structure 301 and the wall 400 is relatively large, but the cover section 10 completely covers the joint. The upper clamping lip 34 is bent upwards, as when inserted into the joint, and rests against the lateral floor finish 331. In this arrangement, the taper at the floor-side end of the upper clamping lip 34 rests against the floor finish 332. As a result, the upper clamping lip 34 wedges the floor finish strip 2 and counteracts any movement of the floor finish strip 2 out of the joint. In addition, the elastic deformation of the upper clamping lip 34 presses the floor finish strip 2 with the wall section against the wall 400, so that the floor finish strip 2 cannot rotate out of the joint. The distance bl is greater than the length of the lower clamping lip 32, so that the lower clamping lip 32 has no contact with the floor finish 331 and protrudes freely into the joint. The significantly longer upper Clamping lip 34 takes over the clamping task and holds the floor trim strip 2 in the joint.

[0051] In Figure 2b, the distance b2 between the floor finish 332 and the wall 400 is smaller than the corresponding distance bl in Figure 1a. As a result, the upper clamping lip 34 is bent further. The taper at the floor-side end of the upper clamping lip 34 no longer lies flush with the floor finish 333, but also counteracts an upward movement of the clamping lip 34 and thus of the floor finish strip 2 and ensures a good fit of the floor finish strip in the joint 2. However, here too, the distance b2 is so large that the lower clamping lip 32 has no contact with the floor finish 331 and protrudes freely into the joint.

[0052] At a small distance b3, as shown in Figure 2c, the upper clamping lip 34 is bent upwards so far that its underside essentially rests against the base end 333. The distance b3 is less than the length of the lower clamping lip 32, and the flexible lower clamping lip 32 is bent upwards with its distal end on the base during installation, thus clamping the base end strip 2. The lower clamping lip 32 assumes the main part of the clamping action here. The taper of the lower clamping lip 32 rests against the base end 333 and counteracts any upward movement.

[0053] This allows the floor trim to be securely clamped into the joint across a wide range of joint widths. The floor trim shown and described here is designed to be self-clamping and can be inserted into the joint without any additional fastening. Installation can be done tool-free by simply pressing it into the joint. Additional fastening with screws, adhesives, or other fasteners is not required, making installation faster and more cost-effective.

[0054] A specialist will adapt the parameters of the floor trim to different situations and, for example, adjust the length of the clamping lips and, if necessary, the material selection and / or thickness to achieve sufficient clamping for different joint widths. It is obvious to the specialist that in addition to Further adjustments and modifications can be made to the examples shown and described.
