EP3130724B1 - Floor profile assembly and base profile - Google Patents

Description

The invention relates to a base profile of a floor profile assembly and the floor profile assembly with base profile and cover for use in joints between adjacent floor coverings.

Generic floor profile arrangements are known in the art. For example, the EP 1 682 735 B1 a floor profile assembly having a hinge arrangement between a base profile and an intermediate profile designed as a holding device for fastening a cover profile. The disclosed solution has in practice many times proven.

Also state of the art are solutions with multiple bending points in the base profile for adjusting the height, for example from the DE 20 2008 000 534 U1 . DE 3420805 A1 or EP 1 680 563 B1 , The from the DE 3420805 A1 However, known solution is aimed at holding the floor covering, without adaptability of the altitude or inclination. The multiple joint with obliquely extending connecting webs according to the other two publications is difficult to install over the length of the rails. In addition, restoring forces are sometimes realized consuming with a spring. Furthermore, in using the plurality of predetermined bending points, it is problematic that individual bending points are easily overloaded and break.

Further prior art in the present technical field is disclosed in the documents DE 20 2012 100290 U1 and WO 2005/042875 A1 disclosed.

As a further development of the existing systems, it has been shown that it is advantageous to reduce the articulation, i. to achieve the inclinability of a cover profile to be fastened to the base profile with a simplified base profile or a smaller number of components and thereby save the previously used intermediate profile or other components such as springs or the like. It is also desirable to reduce the complexity of the system to simplify mountability.

The invention is therefore based on the object to offer a simplified, faster to lay and cheaper system.

This object is achieved by the feature combination according to claim 1.

In a first embodiment of the invention, a base profile of a floor profile assembly with a bottom support leg and a holding device according to claim 1 is proposed, which is formed a cover profile to be fastened. The ground support leg and the holding device are directly and integrally connected by a joint having a predetermined bending point, so that the holding device can be tilted in the transverse direction relative to the ground support leg. Compared to the known solutions, the connection of the holding device is simplified to the bottom support leg. The direct connection via the one joint avoids that the alignment of the holding device must be carried out by multiple inclinations over a plurality of oriented in different directions predetermined bending points. The base profile becomes more compact. The inclination of the holding device relative to the ground support leg takes place directly and exclusively on a single joint. An overload of individual predetermined bending points is excluded. In addition, by the inclination of the holding device to the one joint always exerted a tensile force on the covering profile fixing screws. The base profile thus allows a bias.

In one embodiment, it is provided that the holding device is formed immediately adjacent to the joint. This also contributes to the compact design. In addition, the adjustment of the inclination of the holding device is simplified to a certain angle, since this cooperates directly with the one joint.

In a development of the base profile, the joint having the predetermined bending point is formed by a bending web. The use of such a bending web allows any shaping and in particular also an execution of the predetermined bending point by a local material taper. In an advantageous embodiment, the local material taper is formed by 50-65% relative to a portion of the bending web adjacent to the predetermined bending point. As a local material taper, for example, a desired bending groove can be provided. However, the entire bending web can also be made thinner in the region of the local material tapering. Using of aluminum, the material thickness of the bending web in the region of the material taper is preferably 0.9-1 mm in the transverse direction, in the non-tapered adjacent section at approximately 1.6 mm.

In one embodiment, the holding device has two vertical legs with a screw channel formed therebetween and a transverse leg connecting the vertical legs, so that the holding device is substantially U-shaped. By default, the bending web runs centrally to the transverse leg of the holding device, but in an advantageous embodiment, in a vertical extension to one of the two vertical legs. As a result, the base profile is stretched or shortened in the transverse direction as needed by the width of the holding device.

According to the invention, the bottom support leg has a fastening section for fastening, for example by means of screws on the bottom and a bending section, wherein the bottom support leg in the bending section a plurality of upper side and / or underside alternately arranged and the stiffness locally reducing grooves having a vertical bending of the bottom support leg in the bending section enable. Upper side hereby means directed to the floor covering, directed below the floor. The grooves can be shaped differently and adapted in width in the transverse direction (joint width direction) and depth in the vertical direction, depending on what rigidity in the bending section is desired. In addition, in one embodiment, at least the upwardly directed to the flooring groove edges are formed phased or rounded. As a further positive aspect, the grooves reduce the cost of materials for the base profile.

A preferable ratio of the area portion of the fixing portion to the bending portion is 0.5-1.5, more preferably 0.8-1.2.

In a development of the base profile, it is provided that the ground support leg immediately after the joint has a predetermined bending groove facing the ground. The Sollbiegenut allows the holding device and the joint or the bending web having portion of the base profile is easier to bend vertically above the joint and defined precisely with respect to the position. Due to the vertical bending of the distance is reduced to a aufzusetzenden on the holding cover profile and improves the support between the base profile and cover even with larger flooring thicknesses.

Another embodiment of the base profile is characterized in that the bottom support leg has at least one longitudinally extending recess in the bending section. The recess is preferably a punched-out over a predetermined length in the longitudinal direction (longitudinal direction along the joint). The recess facilitates the flexibility of the holding device and the joint or the bending web having portion of the base profile to vertically above in the joint.

In a non-inventive further alternative embodiment, a base profile of a floor profile assembly is proposed which has a holding device which is adapted to receive a covering profile fastened. The base profile includes a horizontal floor support leg to be secured to the floor. The bottom support leg and the holding device are connected by a transition portion having a step and a relation to the bottom support leg in the vertical direction and extending to the bottom support leg transverse web. The holding device is tiltable relative to the bottom support leg by bending the transition section in the transverse direction along a longitudinally extending step edge of the step. In a non-inclined state of the holding device, the transverse web runs opposite the ground support leg spaced in the vertical direction and parallel to the bottom support leg.

The transverse web extending parallel to the floor support leg provides stabilization of the transition section, whereby a vertical height position of the transverse web and thus of the holding device can be adjusted by bending the holding device relative to the transition section in a first transverse direction and bending the transition section relative to the floor support leg in a transverse direction opposite the first transverse direction is. In other words, the height of the retainer may be increased or decreased from a home position by bending the transition section at two different locations in both opposite transverse directions.

The articulation or inclinability of the holding device, which is conventionally realized by means of a joint arrangement, with respect to the ground support leg to be fastened to the floor is realized by bending the base profile along the step edge. For this purpose, the transition section is provided with a step formation, by which the step edge and thus a defined bending edge are ensured. The bending of the holding device for generating the inclination takes place via a force effect during fastening, by a tool or manually.

In an advantageous embodiment, it is provided that the base profile is formed in one piece and thereby can be dispensed with an additional intermediate profile. The inclinability of the holding device is realized solely by the base profile.

In an advantageous embodiment, the transition section is formed by a web having the step between the bottom support leg and the holding device. Such a step is directed in the vertical direction upwards, towards the holding device, thereby forming a free Section below the transition section between the ground and the bridge, which can be used for the slope.

In a development of the disclosure, it is provided that the transition section has at least one predetermined bending groove on the step, and the retaining device is inclined relative to the ground support leg by bending the transition section on the at least one predetermined bending groove in the transverse direction. The desired bending groove preferably extends over the entire length of the base profile in the longitudinal direction and facilitates the defined bending in the transverse direction.

To connect the transition section to the holding device, the base profile in a favorable embodiment on the transition section on one side a vertical bending leg. The vertical bending leg is in this case preferably arranged on a side lying transversely to the ground support leg, so that the holding device is held on one side at the transition section, which is spaced from the ground support leg.

On the vertical bending leg, a further, in the longitudinal direction extending Sollbiegenut is formed in a development, which provides a further possibility of inclination of the holding device in the transverse direction in addition to the stage.

In the base profile is further provided that the holding device is spaced in the vertical direction relative to the transverse web, so that a free space between the holding device and transverse web is formed for the bending movements.

To facilitate bending, in one embodiment, the material thickness of the transition section in the vertical direction is less than that of the bottom support leg. Also, the material thickness of the transition section in an embodiment variant in the vertical direction is lower as the material thickness of the holding webs of the holding device in the transverse direction. In any case, the size ratios are chosen so that the strength of the base profile is sufficiently high in the transition section to keep the floor covering pressed on the floor via a cover.

In this exemplary embodiment, too, a groove extending in the longitudinal direction can be formed on the base support leg of the base profile, at least in an area adjoining the transition section. Additionally or alternatively, it may further be provided that in this area or within the groove longitudinally spaced recesses, i. the bottom support leg completely pierced punch holes are formed. This facilitates the bending of the transition section and thus the assembly.

The invention further includes a floor profile assembly having a base profile described above and a cover profile attachable thereto, which is tiltable together with the holding device relative to the bottom support leg and in a further development also height adjustable. The bending of the holding device of the base profile to produce the inclination can be done via a force when fastening the cover, in particular by tightening screws.

In a favorable development of the base profile is provided that the cover has two retaining legs, which are designed to overlap the vertical leg of the holding device, wherein at least one of the retaining legs, a vertical extension portion is formed, which engages in the mounted state in the recess on the bottom support leg. As a result, the variability of the interaction of cover and base profile is extended in the vertical height direction, so that the cover is pushed deeper in the vertical direction on the base profile.

Preferably, the base profile and / or the cover profile made of aluminum manufactured.

Like reference numerals designate like parts throughout the views. The reference numerals are not completely repeated in all figures, as far as it is the same component.

In the Figures 1 and 2 an embodiment of a non-inventive base profile 1 is shown in a side view. The base profile assembly is integrally formed with a horizontal, to be fixed to the ground support leg 4, an immediately adjacent transition section 5 and an immediately adjacent holding device 2, wherein the holding device 2 has two vertical legs 21, 22 formed therebetween with screwing channel 23 The holding device 2 has a Extension in the transverse direction Q on that their left vertical edge plane substantially terminates with the boundary between the transition section 5 and the bottom support leg 4.

The transition section 5 comprises a step 6, which increases a transverse web 11 in the vertical direction V relative to the bottom support leg 4 essentially by the material thickness of the bottom support leg 4, wherein a clearance 12 remains between the support device 2 and the crossbar 11. The step 6 has a step edge 7 extending in the longitudinal direction L, along which the holding device 2 is tiltable relative to the bottom support leg 4 by bending the transition section 5 in the transverse direction Q by an angle α, as shown in FIG FIG. 2 is shown. Of course, the holding device 2 can also be inclined in the opposite direction by an angle α. In FIG. 1 is the holding device 2 in a non-tilted basic position. The crossbar 11 runs parallel to the ground support leg. 4

Along the step edge 7 an extending in the longitudinal direction L Sollbiegenut 8 is introduced, so that the holding device 2 relative to the bottom support leg 4 by bending the transition section 2 on the Sollbiegenut 8 in the transverse direction Q is easier and further tilted. Alternatively, the Sollbiegenut in the longitudinal direction L may be provided only in sections.

The transverse web 11 merges on a side facing away from the bottom support leg 4 in the transverse direction into a vertical bending leg 9, to which the holding device 2 adjoins. On the bending leg 9 a second longitudinally extending Sollbiegenut 10 is formed on the outside, which also allows an inclination of the holding device 2 in the transverse direction. In this case, this second inclination can take place in the same transverse direction as in the opposite transverse direction. With opposite bending of the holding device 2, ie in both transverse directions Q1 and Q2 according to Fig. 5 , along both Solfbiegenuten 8, 10, the vertical height position of the holding device 2 is reduced. As a result, lower floor coverages can be built with one and the same base profile 1.

The FIGS. 3 and 4 show the floor profile assembly with the base profile 1 from FIGS. 1 and 2 with a cover profile 3 fastened thereto by screws (not shown), which engages around the vertical legs 21, 22 of the holding device 2 on both sides laterally with retaining legs 31. About a nose 32, the cover is locked between the vertical legs 21, 22. Lateral cover wings 33 are according to FIG. 3 on the adjacent floor covering 40 each have the same thickness and are bendable over the holding leg 31 adjacent longitudinal grooves 34. In FIG. 4 is the floor profile assembly with inclined holding device 2 of the base profile 1 from FIG. 2 and thus inclined arranged cover profile 3, wherein the covering wings 33 of the cover 3 different thicknesses floor coverings 41, 42 cover.

FIG. 5 corresponds to the version according to FIG. 3 However, the base profile 1 has been bent back at the Sollbiegenut 8 in the transverse direction Q1 and the Sollbiegenut 10 in the transverse direction Q2, so that the cross bar 11 is closer to the ground and the holding device 2 has a lower vertical height, but is not inclined. The Sollbiegenut 8 is compressed, the Sollbiegenut 10 further clamped. In this way, a floor covering 43 can be covered with a material thickness B which is less than the material thickness A of the floor covering 40 FIG. 2 ,

Not shown in a figure, but equally possible is an increase of the holding device 2 by bending in the opposite direction, i. the holding device 2 along the Sollbiegenut 8 in the transverse direction Q2 and along the Sollbiegenut 10 in the transverse direction Q1.

The material thickness of the step 6 forming web or transverse web 11 of the transition section 5 is formed thinner in the vertical direction than that of the bottom support leg 4 and thinner than the width of the vertical leg 21, 22 in the transverse direction Q.

FIG. 6 shows the base profile 1 in a plan view. At the bottom support leg 4 of the base profile 1, a groove 41 extending in the longitudinal direction L is formed in the region adjoining the transition section 5, within which a plurality of longitudinally spaced recesses 42 are provided. The length of the recesses 42 is freely selectable and adaptable to the material thickness, so that a balance between easy bending for easy installation on the one hand and sufficient strength for holding the floor covering on the ground on the other hand is ensured.

In the FIGS. 7-10 Embodiments of a base profile according to the invention 50 are shown without and with cover 3 in a side view. The bottom support leg 4 and the holding device 2 are direct and integrally connected by a formed on the bending web 9 hinge 51 having the predetermined bending point 52. About the generated by the predetermined bending point 52 joint 51 is in the ground state at right angles to the ground support leg aligned holding device in the transverse direction Q relative to the bottom support leg 4 tilted. The predetermined bending point 52 is formed by a local material taper of the bending web 9 in the transverse direction with respect to the adjacent sections without material taper. As in the previous embodiments, the holding device 2 comprises two vertical legs 21, 22 with a screwing channel 23 formed therebetween. The vertical legs 21, 22 each comprise projections 59 which, in addition to inclinability, expand the pivoting range of a covering profile 3; as in Fig. 10 shown.

According to the statements after the FIGS. 7 and 8 the bending web 9 extends in vertical extension to the vertical leg 21 or 22, ie substantially in one and the same vertical plane. In the execution according to FIG. 9 engages the bending web 9 in the middle of the holding device 2.

In all versions according to the FIGS. 7 to 10 For example, the ground support leg 4 has a fastening portion F for attachment to the ground, for example by means of screws, not shown, and a bending portion B. The bottom support leg 4 comprises in the bending section B a plurality of upper side and lower side alternately arranged and the rigidity locally reducing grooves 53, 54, which allow the vertical bending of the bottom support leg 4 in the bending section B, as shown by the arrow. The holding device 2 is raised by the bending of the bending section B vertically into the joint. As a fulcrum, one of the grooves 53, 54 serve, depending on where the floor covering, not shown, ends. The execution according to FIG. 9 In addition, comprises a pointing to the ground Sollbiegenut 55 on Bodenauflageschenkel 4 in the bending section B, the provides a defined degree of freedom to inclinability of the bottom support leg 4 at the Sollbiegenut 55. The Sollbiegenut 55 can be readily provided in the other embodiments, even if it is not shown there.

Referring to FIG. 10 is a joint bridging arrangement with the base profile 50 off FIG. 7 and a cover profile 3 in a vertically uppermost position. The cover profile 3 has two retaining legs 31, which engage over the vertical legs 21, 22 of the holding device 2. On the left in the figure holding leg 31, the vertical extension portion 58 is formed, which can engage in the mounted state in the lowest position in the provided on the bottom support leg 4 and extending in the longitudinal recess 42.

The invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a number of variants is included, which makes use of the illustrated solution even in fundamentally different versions. For example, cover profiles with only one holding leg or corner edge profiles can be used as cover profiles. Also included in the invention is the use of the base profile with a closure profile on a covering edge.
