Description

[0001] The invention relates to a stair step arrangement, with at least a stair step comprising a (e.g. horizontal) tread and a (e.g. vertical or substantially vertical) riser, a repair angle profile attached to the stair step (at the transition from the tread to the riser) comprising a tread leg associated with the tread (and resting on the tread) and a riser leg associated with the riser (and abutting the riser), as well as a curved transition section connecting the tread leg to the riser leg, a floor covering laid on the tread (and the tread leg of the repair profile) as the tread covering, and a floor covering laid on the riser (and the riser leg) as the riser covering.

[0002] Furthermore, the invention relates to a repair angle profile, also referred to as a repair angle, which is intended for the refurbishment or repair of a stair step.

[0003] The stair tread assembly can also include an additional trim profile that covers the tread and riser at the transition between the tread and riser, and thus also the repair angle installed in this area, effectively concealing it as a trim profile. This trim profile, also known as a stair nosing profile or simply a stair nosing, covers the transition from the tread to the riser, and therefore primarily the transition from the flooring laid on the tread to the flooring attached to the riser. To install such a trim profile correctly, level surfaces are required. For example, if a stair tread with a worn or broken edge is being repaired, the edge must be repaired before installing the trim profile and before laying the flooring.The transition from the tread to the riser is reinforced with the repair angle and, if necessary, a leveling compound, such as a suitable repair mortar. After the edge has been reinforced with the repair angle and, if necessary, a leveling compound, the floor coverings are laid, and then the transition can be covered with the trim profile. The repair angle, which is preferably a metal angle profile, is therefore of particular importance in the repair and / or renovation of stair treads.

[0004] A stair tread arrangement of the type described, in which such a repair angle is used, is known, for example, from DE 86 30 213 U1. The repair angle is essentially L-shaped, with the curved transition section being slightly raised compared to the flat tread leg, so that sufficient space is available for a leveling compound, e.g., a repair mortar. After the repair angle and the leveling compound have been installed, a flat bearing surface for the upper floor covering is available on the tread.

[0005] Problems arise in practice with such repair angles, particularly when not only the tread but also the riser is covered with a floor covering, e.g., a resilient floor covering. In practice, movement or displacement of the floor covering can occur in the area of ​​overlap, which in turn can lead to damage to the stair nosing installed in this area, i.e., the cladding profile. Such damage to the stair nosing (i.e., the cladding profile) is not only visually unappealing but also increases the risk of accidents on the stairs. The invention aims to remedy this problem.

[0006] Separately, German patent DE 296 08 629 discloses a special, strip-shaped cover element for the leading edge of a stair tread, comprising a flat upper section, a lower section, and a middle section, with the middle section extending in an arc around the leading edge of the stair tread. This is intended to allow a stair covering, such as a carpet, to be easily and completely laid on the cover profile and thus in an arc around the leading edge.

[0007] JP S5144126 U describes another special profile for cladding a stair tread, designed as an anti-slip profile. The cladding profile has two legs that are hinged together via an arc-shaped section, allowing the profile, which is flat when delivered, to be unfolded and installed. One of the legs is already permanently attached to an anti-slip strip upon delivery. After installing this cladding profile with the anti-slip strip, a floor covering can be laid on the tread, abutting the anti-slip surface of the cladding profile and, for example, abutting the end of the anti-slip strip.

[0008] Finally, DE 20 2007 004 592 U1 discloses a component for encasing stair tread edges, consisting of an L-shaped angle profile rail, one leg of which is designed to rest on the tread and can be fixed in place, and the other leg of which runs against the face of the stair tread, wherein the angle profile rail is provided with an attached covering. This covering is a rigid, self-resilient angle piece that extends over the entire L-shaped angle profile rail and is self-retainingly fixed to it.

[0009] Based on the prior art and the problem described at the outset, the invention aims to create a stair tread arrangement with a repair angle profile, or such a repair angle profile, which, with a simple and cost-effective design, is characterized by improved functionality and, in particular, avoids problems in the installation of floor coverings in both the tread and riser areas.

[0010] To solve this problem, the invention teaches, in a generic stair tread arrangement of the described type, that the transition section of the repair angle or repair angle profile is designed as a spacer lug which (in the assembled state) is arranged between the tread (or the underside of the tread) and the riser (or the upper end face of the riser), so that the tread (i.e., its underside) is spaced apart from the riser (i.e., its upper end face) and consequently arranged with a gap. The gap is more than 2 mm, preferably more than 4 mm, e.g., more than 5 mm.

[0011] According to the invention, a modified and optimized repair angle is provided, which allows the problems described above to be avoided in a simple and economical manner. This is because the repair angle is characterized by a specially designed transition section that not only forms a curved transition from the (e.g., horizontal) tread to the (e.g., vertical) riser, but also constitutes a spacer lug that separates the tread material arranged on the step from the riser material arranged on the step, thus preventing contact between the underside of the tread material and the upper end face of the riser material. This prevents loads on the tread from being transferred to the riser material, reliably preventing movement in the area of ​​the overlapping material.Forces acting on the tread when a load is applied are not transferred to the riser, but rather to the repair angle and thus, via the spacer lug, to the riser leg of the repair profile attached to the riser, without putting any load on the riser itself. Preventing movement in the overlapping area of ​​the treads reduces the risk of damage to the stair nosing, also known as a stair nosing profile or trim profile. This significantly reduces the overall risk of accidents on stairs in the area of ​​repaired stair treads.

[0012] The invention relates not only to the described stair tread arrangement, which comprises, on the one hand, the stair tread and the floor coverings, namely the tread and the riser, and, on the other hand, the repair angle. The invention also relates to the described repair angle profile, which is particularly useful for the repair of a stair tread and is preferably used within a stair tread arrangement of the described type. The repair angle profile has a tread leg associated with the tread and a riser leg associated with the riser, wherein the tread and riser legs are oriented transversely to each other and preferably perpendicular to each other or substantially perpendicular to each other. Furthermore, the repair angle profile has a transition section connecting the tread leg to the riser leg.According to the invention, this (curved) transition section is designed as a spacer lug which – when mounted on a stair tread – can be positioned between a tread covering that can be laid on a step and a riser covering that can be laid on a riser, in order to space the tread covering from the riser covering. The described repair angle profile is therefore also separately protected. Preferred embodiments of the repair angle profile are described below.

[0013] The spacer lug of the repair angle profile, which ensures a distance between the tread and the riser, is of particular importance according to the invention. Preferably, the spacer lug projects or extends with its front end, which is the end facing away from or pointing away from the riser, a (first) dimension beyond the riser leg. This also means that the riser leg is set back by this (first) dimension relative to the front end of the spacer lug and consequently recedes. This spacer lug, projecting forward beyond the riser, reliably prevents contact between the tread and the riser using simple means, because even if the tread is laid on the spacer lug and up to its front end, the (separate) riser laid below the spacer lug remains spaced and separated.It is advantageous if this (first) dimension is greater than or equal to the thickness of the floor covering used, and in particular greater than or equal to the thickness of the underlayment. In principle, the spacer lug also fulfills its spacing function when a floor covering, and especially an underlayment, is used with a thickness greater than the length of the spacer lug. The aforementioned (first) dimension by which the spacer lug projects can also be referred to as the length of the spacer lug. This length, or the first dimension of the spacer lug, can be, for example, 1 mm to 8 mm, preferably 2 mm to 6 mm, and particularly preferably 2 mm to 5 mm.

[0014] Optionally, the spacer lug can (also) be positioned raised by a (second) dimension relative to the tread, i.e., the tread is lowered relative to the spacer lug or its upper end, for example, by a (second) dimension of at least 0.5 mm, preferably at least 1 mm, e.g., 0.5 mm to 2 mm. This allows sufficient space to be created, in a generally known manner, for the application of a leveling compound, e.g., a repair mortar, in the area of ​​the tread, so that after the repair angle profile has been installed and a leveling compound applied, a sound bearing surface for the floor covering is available in the area of ​​the step.

[0015] The repair angle profile is preferably made of metal, e.g., sheet steel. However, the invention also includes embodiments made of other materials. The (inner) repair angle profile is to be distinguished from the (outer) cover profile or cladding profile also described, which is preferably made of plastic, e.g., by extrusion or co-extrusion.

[0016] The floor covering is preferably a relatively thin covering and, in particular, an elastic or flexible covering. This could be, for example, a covering made of PVC, vinyl, linoleum, or carpet. Preferably, the same floor coverings, or coverings of the same type (i.e., made of the same material and with the same thickness), are used for both the tread and riser surfaces. However, the invention also includes embodiments in which the tread differs from the riser surface in terms of material and / or thickness. In all cases, however, the riser surface is separate from the tread surface; that is, they are separate coverings, distinct from a covering laid in one piece around a stair edge.

[0017] The repair angle profile preferably has a profile thickness of 0.3 mm to 1.5 mm, e.g., 0.5 mm to 1 mm. Preferably, the repair angle profile has the same thickness across its entire cross-section. However, embodiments are also possible in which the thickness varies across the cross-section, for example, by having the step leg have a different thickness than the set leg, or by having different areas of a leg have different thicknesses. Preferably, however, such varying thicknesses lie within the thickness range specified above.

[0018] The tread and the riser can be of different lengths or, alternatively, the same length. Preferably, the tread is longer than the riser, so that the profile has an approximately L-shaped cross-section. The tread can, for example, have a length of 20 mm to 80 mm, or 30 mm to 60 mm. The riser can, for example, have a length of 10 mm to 50 mm, or 15 mm to 40 mm.

[0019] The tread and riser legs can each be designed as solid legs that—apart from holes for fasteners—have no further openings. However, the tread leg is particularly preferably provided with recesses, specifically recesses arranged side by side in the longitudinal direction of the profile. Mounting areas are formed between the recesses, in which preferably holes (or similar openings) for fasteners, e.g., for screws, nails, pins, or the like, are arranged. This design with recesses and mounting areas serves to improve fastening and simultaneously ensure optimal embedding in, for example, a leveling compound such as mortar or the like. While it is possible to also provide the riser leg with recesses and mounting areas, it is preferably designed as a solid surface without openings, only with mounting recesses.

[0020] The repair angle profile is preferably manufactured by a bending process; that is, the angle profile is produced from a flat profile, e.g., a flat sheet, by bending. If recesses are provided in the profile legs, these can be created by an additional processing step, e.g., by punching or cutting. A cutting process can preferably be carried out by a laser cutting process, and consequently by laser cutting. Preferably, the recesses are first created, e.g., by punching or cutting, and then the angle profile is bent.

[0021] The invention will now be explained in more detail with reference to the drawings, which merely illustrate exemplary embodiments. The drawings show: Fig. 1 a stair tread arrangement according to the invention in a simplified side view, Fig. 2 a repair angle profile according to the invention in a side view, Fig. 3 the repair angle profile according to Fig. 2 in a top view of the step leg, Fig. 4 the repair angle profile according to Fig. 2 in a side view of the setting leg, Fig. 5 a modified embodiment of the object according to Fig. 2 , Fig. 6 the angle profile according to Fig. 5 in a top view of the step leg and Fig. 7 the repair angle profile according to Fig. 5 in a side view of the seat leg.

[0022] In Fig. 1Figure 1 shows a stair tread arrangement comprising a stair 1 with a horizontal tread 2 and a riser 3 oriented vertically to it. A floor covering 4 is arranged on the tread as the tread covering 4, and a floor covering 5 is arranged on the riser as the riser covering 5. The edge area 1 of this stair tread is covered with a cover profile 6, which optionally has an anti-slip function by means of an anti-slip coating 7 arranged on its upper surface. In the course of repairing a stair tread, which may be broken or damaged, for example, in the area of ​​the tread edge, a repair angle profile 8 is installed according to the invention before the installation of the cover profile 6 and also before the installation of the floor coverings 4, 5. The repair angle profile 8 ensures, for example, that...In the case of worn or broken tread edges of a step, a proper substrate with level bearing surfaces must be created before laying the floor coverings 4, 5. For this purpose, after attaching the repair angle profile 8, the area of ​​the tread is filled with a leveling compound, e.g. a filler compound 9 (see . Fig. 1 ).

[0023] The in Fig. 1The repair angle profile 8 shown is of particular importance according to the invention. It has a tread leg 10 associated with the step 2 and a riser leg 11 associated with the riser 3, as well as a curved transition section 12 connecting the tread leg 10 with the riser leg 11. According to the invention, the transition section is designed as a spacer lug 12, which – in the installed state of the repair angle profile 8 and in the installed state of the floor coverings 4, 5 – is arranged between the tread 4 and the riser 5, so that the tread 4 is spaced apart from the riser 5. For this purpose, in Fig. 1It can be seen that the spacer lug 12 of the repair angle profile 8 is positioned between the underside of the tread 4 and the upper end face of the riser 5, such that the spacer lug 12 separates and distances the underside of the tread 4 from the upper end face of the riser 5. This ensures that loads on the tread 4 in the area of ​​the tread edge are not transferred to the riser 5, but are instead introduced into the repair angle profile 8 without subjecting the riser 5 to any load. In this way, damage and, in particular, movement between the tread 4 and the riser 5 are prevented. This, in turn, prevents damage to the cover profile 6, which is mounted in the area of ​​the tread edge, during use.

[0024] This shows Fig. 1The repair angle profile 8 according to the invention is shown in its assembled state in the area of ​​the tread edge of a stair 1. The essential spacer lug 12 projects with its front end E, which faces away from or points away from the riser, by a first dimension x beyond the riser leg 11 or the front plane of the riser leg 11, such that the riser leg 11 is set back or recessed by this first dimension x relative to the front end E of the spacer lug 12. This design enables the lower floor covering 5, namely the riser 5, to be fastened below the spacer lug 12, so that, according to the invention, contact between the tread 4 and the riser 5 is prevented. The first dimension x by which the spacer lug 12 projects beyond the riser leg 11 can also be referred to as the length x of the spacer lug 12. This first dimension x can be, for example, B. 1 mm to 8 mm, preferably 2 mm to 6 mm, particularly preferably 2 mm to 5 mm.As a rule, it is advantageous if the first dimension x is greater than or (approximately) equal to the thickness of the floor covering 4, 5, namely preferably the settling covering 5.

[0025] Furthermore, it can be seen in the figures that the spacer nose 12 or the transition section 12 not only projects forward and consequently beyond the setting leg 11, but also projects upward beyond the foot leg 10 and is therefore arranged raised by a second dimension y relative to the foot leg 10, i.e., the foot leg 10 is lowered relative to the upper end F of the spacer nose 12 by a second dimension y, which is, for example, 0.5 mm to 2 mm. This design enables, in particular, perfect compensation using the Fig. 1 The filler compound 9, also shown, is applied so that a perfectly level and even surface is available overall.

[0026] The in Fig. 1 The repair angle profile 8 shown in the assembled state is in the Figures 2 to 7 The various embodiments are shown separately in their unassembled state. Figures 2 to 4 a first embodiment of the repair angle profile, which according to the embodiment Fig. 1 corresponds. Figures 5 to 7 Figure 1 shows a modified, second embodiment of the invention. In both cases, the front end E of the spacer nose 12 is formed by an arcuate section 12a, which in the exemplary embodiment has a semicircular cross-section.

[0027] In the embodiment according to Fig. 2 The arc-shaped section 12a extends over an arc angle of, for example, 150° to 200°. At its upper end, the arc-shaped section 12a transitions via a straight, ramp-shaped section 12b into the horizontal step leg 10. At its lower end, the arc-shaped section 12a transitions via a curved section 12c into the vertical setting leg 11.

[0028] In contrast, the second embodiment shows Fig. 5 An arc-shaped section 12a extends over a smaller arc angle, e.g., an arc angle of, for example, 70° to 120°. This arc-shaped section 12a also transitions at its upper end into the horizontal step leg 10 via an upper, straight, ramp-shaped section 12b. However, at its lower end, this shortened arc-shaped section 12a does not transition directly into the vertical support leg 11, but rather via a lower, straight, ramp-shaped section 12d. In this exemplary embodiment, this lower, ramp-shaped section 12d is arranged at an angle α of approximately 30° to 60° to the base plane of the support leg.

[0029] The radius of curvature of the arc-shaped section can be, for example, 1 mm to 3 mm, or approximately 2 mm, in both embodiments. In the illustrated embodiment, the length L1 of the footplate (to the front surface of the footplate) is 40 mm, and the length L2 of the footplate (to the surface of the footplate) is 20 mm. However, these dimensions can be varied within the scope of the invention and adapted to the respective requirements.

[0030] The repair angle profile 8 is preferably manufactured as a sheet steel profile. The setting leg 11 can be designed as a solid sheet steel leg with no openings other than optional mounting holes for fasteners. This is in Figures 4 and 7This is evident. In contrast, the step leg 10 is provided with a plurality of recesses 13a, 13b, which are arranged next to each other in the longitudinal direction L of the profile, so that mounting areas 14 are formed between the recesses 13a, 13b, which have, for example, bores 15 for fasteners, e.g., screws. This is, for example, in Fig. 3 recognizable. During assembly, the recesses 13a, 13b between the assembly areas 14 are filled with the filler compound 9, as shown in Fig. 1 is shown.

[0031] The following show Figures 2 to 4 A configuration of profile 8, designed for the renovation of a stair tread made of stone, concrete, or the like. The recesses in the tread leg 10 are designed as closed openings 13a, separated from one another by the intervening mounting areas 14. Mounting holes 15 are also provided in the tread leg. The riser leg 11 is designed according to Fig. 4 designed as a flat leg without openings and also without mounting holes.

[0032] In contrast, the Figures 5 to 7 An alternative design of a repair angle profile 8, in which the tread leg and optionally also the riser leg are designed for the repair of a wooden stair tread. For this purpose, the profile features according to Fig. 6 a step leg in which the recesses are designed as open recesses 13b, between which the mounting areas 14 are arranged, wherein bores for fasteners may in turn be provided in the mounting areas 14. The step leg is designed according to Fig. 7 It is again designed as a simple or solid flat leg without major openings. Only standard mounting holes are provided.

[0033] The mounting profile 8 is adapted by appropriately designing the step leg 10 and the setting leg 11. The in the Figures 2 and 5 The various variants of the essential spacer nose 12 shown in the illustration can, however, be implemented independently of the intended use (for wood or stone). This means that the variants shown in the Figures 3 and 4 illustrated design of step leg 10 and set leg 11 not only in the profile shape according to Fig. 2 , but equally in terms of profile shape Fig. 5 is feasible and the ones in the Figures 6 and 7 The illustrated design of the step leg 10 and the set leg 11 can be implemented in the same way in the profile shape according to Fig. 2 to be realized.
