Definitions

  • the invention relates to a profiled rail system for covering at least one lining edge according to the preamble of patent claim 1.
  • a skirting board made of plastic in which a permanent magnet is held.
  • a sheet metal strip is mounted to which the permanent magnet of the skirting board adheres. Since the baseboard has no adjustment, despite a fixed mounting of the permanent magnet in the baseboard in the simplest way a direct contact of the permanent magnet can be realized with the metal strip.
  • a magnetic fastener assembly for covering a joint or edge is known.
  • This arrangement has a base rail and a cover rail, which are adjustable against each other.
  • the base rail is fixed to a base, while the cover rail overlaps covering edges.
  • permanent magnets are provided in the base rail and in the cover rail, which are poled against each other. This allows the cover rail to be pulled with bias against the adjacent pads.
  • no fasteners are visible. This arrangement has been well proven in practice and forms the starting point of the present invention.
  • U1 is a generic cover assembly with magnetic system, consisting of a base rail and a cover rail, known.
  • the cover rail has a tooth profiling, which engages in a correspondingly profiled intermediate part. In this way, a height adjustment of the cover rail is achieved.
  • This intermediate part is connected via a cylindrical magnet with the base part, so that the cover rail is pivotable relative to the base rail.
  • the invention has for its object to provide a profile rail system of the type mentioned, which is characterized by improved functionality.
  • the profiled rail system according to claim 1 serves to cover at least one lining edge.
  • the covering can be made of any materials such as laminate, Wood, parquet, a polymer, natural or artificial stone. However, this list is not meant to be exhaustive, but merely exemplary. If the profile rail system covers only one lining edge, it serves as edge termination or ramp. Alternatively, however, the profile rail system can also cover several covering edges, so that it is provided between two coverings, in particular in an expansion joint or a lining transition between two different coverings.
  • the profile rail system can be used on floor, wall and ceiling coverings as well as a skirting board or stair nosing profile. Again, this is only an example and not meant to be exhaustive.
  • the profile rail system has a base rail, which is preferably fixable to a substrate. For fixing screws, dowels or adhesive bonds are preferably used. The determination on a surface is not mandatory.
  • the base rail can engage under the adjacent covering with a leg in order to achieve a fixation of the base rail in this way.
  • the profile rail system has a cover rail, which is adjustable relative to the base rail.
  • the covering rail is displaceable relative to the base rail, in order in this way to achieve a height adjustment of the covering rail to the thickness of the respective, adjacent covering.
  • at least one permanent magnet is provided, which pulls the cover rail against the base rail.
  • this permanent magnet should exert a pulling force on the cover rail in order to prevent it from coming off to draw adjacent covering.
  • it has been found to be disadvantageous to realize this tensile force by two magnets with respect to each other.
  • very different magnetic field strengths which may even lead to repulsion of the magnets in each case.
  • This problem has in particular led to the fact that magnetic profiled rail systems for covering pavement edges could not prevail so far.
  • To solve this problem is dispensed with polarity against each other magnets and instead formed both the base rail and the cover rail at least in the partial area magnetizable.
  • the permanent magnet functionally neither belongs to the base rail nor to the cover rail, but represents a both rails positively connecting Ilaltesch.
  • the base rail or the cover rail is magnetized always and independently of the respective rail geometry opposite pole to the permanent magnet, which allows a consistently high tensile force of the cover rail against the base rail over the entire adjustment of the cover rail.
  • a magnetic holding system for the cover rail is practical and can make good use of its particular advantages.
  • the holding system in contrast to a screw from the outside in no way visible. After the cover rail is held in contrast to latching connectors only frictionally and not form-fitting, is a removal of the cover rail of the base rail by overcoming the holding force easily possible.
  • the space under the cover rail can be made easily accessible. This is especially important for revision work.
  • the space under the cover rail can be easily used as a cable channel, and even after completion of the profile rail system, a cable can be retracted or replaced.
  • Due to the magnetic support of the cover rail there is also no signs of fatigue of the retaining mechanism of the cover rail, which are known for example in latching connectors.
  • magnetizable materials for the base rail and the cover rail in particular ferromagnetic materials have been proven, as they can achieve a much higher coercive force compared to paramagnetic materials.
  • iron, cobalt and / or nickel and alloys prepared therefrom are used. Since many ferromagnetic materials have a high hardness, they are difficult to work. In addition, ferromagnetic materials are often subject to corrosion.
  • a major problem of permanent magnetic holding systems is the dependence of the Lorentz force on the distance between the magnet on the one hand and the ferromagnetic material on the other. This force decreases with the third power of the distance, so that in permanently mounted permanent magnets only in a very small height adjustment range, a sufficient holding force can be realized.
  • the permanent magnet in different positions of the cover rail in touching contact with the base rail and the cover rail is freely adjustable between the base rail and the cover rail.
  • the permanent magnet could also be pivotally mounted, but this is not usually necessary.
  • the mutual distance between the permanent magnet on the one hand and the cover or base rail on the other hand always equal to zero, so that the permanent magnet in each position of the cover rail relative to the base rail can develop its maximum force. This ensures a large height adjustment range, which can cover all types of flooring occurring in practice with a profile rail system.
  • a simple realization of the contacting contact of the permanent magnet is obtained by arranging the permanent magnet at an acute angle to the base or covering rail.
  • the base rail or the cover rail are each formed at least two pieces.
  • This rail has at least one non-ferromagnetic profiled rail on which at least one ferromagnetic metal sheet is held.
  • the magnetizable material does not have to be brought into the usually complicated shape of the rail. Rather, it is sufficient to produce a more or less thin sheet metal strip from the ferromagnetic material.
  • the rail can be made of an easily deformable, castable or extrudable material, so that even complicated shapes can be produced inexpensively. By contrast, such production methods can not be implemented with reasonable effort for ferromagnetic materials.
  • a simple sheet metal strip of ferromagnetic material can be easily manufactured at low cost.
  • the rail has at least one undercut holder, in which the ferromagnetic sheet is inserted.
  • This holder may for example be formed by two vertical webs, which are undercut on mutually facing sides. These webs, together with a base leg of the base rail, form a pocket in which the ferromagnetic metal sheet is held.
  • the undercut of the holder the ferromagnetic sheet can withstand tensile forces exerted by the permanent magnet.
  • the permanent magnet By changing the angle of attack of the permanent magnet to the base or covering rail according to claim 4, the permanent magnet always remains in contact with the base rail and the cover rail. In this way, the desired tensile force of the permanent magnet is maintained in different heights of the cover rail.
  • the permanent magnet is rounded at contact points with the base or cover rail.
  • This rounding provides an increase in the effective effective area of the permanent magnet.
  • This effective area would be relatively small with a razor-sharp edge of the permanent magnet, since only a linear contact of the permanent magnet would be ensured and already increases at a small distance from the contact line of the mutual distance between the permanent magnet on the one hand and the base or cover rail on the other hand very quickly.
  • the mutual increase in spacing is reduced by the rounded formation of the permanent magnet by a multiple, so that a significantly larger area around the contact line contributes to the magnetic flux. In this way, the Lorentz force is increased, which is proportional to the cross-sectional area of the magnetic flux.
  • the covering rail is to be height-adjustable and pivotable, then it is favorable according to claim 6 if the rounding is crowned.
  • the enlargement of the cross-sectional area of the magnetic flux is achieved in two dimensions, so that the permanent magnet is pivotable about two axes.
  • the height and on the other hand, the angular position about a longitudinal axis of the cover rail can be adjusted without reducing the force of the permanent magnet.
  • This non-ferromagnetic material can be, for example, a plastic, aluminum, copper or the like, although this list is not meant to be exhaustive, but merely by way of example.
  • the cover prevents a surface contact of the permanent magnet on the ferromagnetic material, so that the holding force between the cover rail and the base rail remains within reasonable limits even during assembly of the profile rail system.
  • the contact surface of the ferromagnetic material with the permanent magnet may not be formed plan. This contact surface could for example be curved or folded.
  • the permanent magnet has opposite magnetic poles at its contact points with the base or cover rail.
  • the full length of the permanent magnet can be used to adjust the cover rail relative to the base rail.
  • the FIG. 1 shows a profiled rail system 1 for covering two edges 2 of coverings 3.
  • the profile rail system 1 has a base rail 4 and a cover rail 5.
  • the base rail 4 has a base leg 6, which can be fixed to a substrate 7.
  • the base leg 6 has a plurality of holes 8, which can be penetrated by screws, not shown.
  • the base rail 6 can either be bolted directly to the substrate 7, glued or indirectly fixed by dowels on this.
  • the base rail 4 also has two vertical guide webs 9, which limit the lateral mobility of the cover rail 5 and facilitate the assembly of the profile rail system 1 in this way.
  • a variant is conceivable that does not require the guide webs 9.
  • each holding web 10 is provided at the base leg 6 of the base rail 4 , each having mutually facing undercuts 11.
  • These holding legs 10 form a holder 12 for a ferromagnetic sheet 13, which is inserted into the holder 12.
  • the undercut 11 of the holding webs 10 is dimensioned particularly small in this case.
  • the base leg 6 forms together with the guide legs 9 and the holder 12 a rail 14, which in the illustrated embodiment in one piece as extruded Part is made.
  • This rail 14 together with the ferromagnetic metal sheet 13 forms the base rail 4.
  • the cover rail 5 has two covering wings 15 which cover the two covering edges 2.
  • the cover rail 5 has two guide webs 16, which cooperate with the guide webs 9 of the base rail 4 and realize the guiding action.
  • a holder 17 is provided for a further ferromagnetic sheet 18.
  • This holder 17 is like the holder 12 of the base rail 4 provided with an undercut 19.
  • the undercut 19 may be formed in the same way as the undercut 11 of the base rail 6. In particular, it is envisaged to make the ferromagnetic sheet 18 in the holder 17 inserted or clickable.
  • the tensile force is realized by a plurality of permanent magnets 20, which are employed at an acute angle 21 to the base rail 4. These permanent magnets 20 are distributed over the length of the profile rail system 1, wherein in the FIG. 1 only one of the permanent magnets 20 can be seen.
  • the permanent magnet 20 is rounded at contact areas with the ferromagnetic sheets 13, 18 so as to form the cross section of the magnetic flux and thus to increase the force effect of the permanent magnet 20.
  • a rounding 22 is cylindrically shaped. It does not matter whether this rounding is circular, elliptical, parabolic or otherwise cylindrical.
  • the permanent magnet 20 In a contact region with the cover leg-side ferromagnetic metal sheet 18, the permanent magnet 20 has a rounded curvature 23.
  • This spherical rounding 23 allows, in contrast to the cylindrical rounding, a pivoting of the cover rail 5 about a longitudinal axis of the profiled rail system 1, without reducing the cross section of the magnetic flux to a single point.
  • Alternatively to the illustrated embodiment according to FIG. 1 is also thought to form both cylindrical contact areas of the permanent magnet 20 or both spherical. Even with spherical rounding 23 of the permanent magnet 20, the concrete form is basically irrelevant.
  • the permanent magnet 20 may have the shape of a sphere, an ellipsoid, a paraboloid or another shape in the region of the spherical rounding 23.
  • the ferromagnetic sheet 13, 18 is partially covered by a non-ferromagnetic material 24.
  • the angle of attack 21 of the permanent magnet 20 can not be reduced to zero, so that in each position, which can take the permanent magnet 20, a substantially line-like or point-like contact with the ferromagnetic sheet 13, 18 is given.
  • a surface contact of the permanent magnet 20 is excluded due to the shape, so that it is possible to dispense with the non-ferromagnetic material 24.
  • the permanent magnet 20 has a linear contact point 25 with respect to the ferromagnetic metal sheet 13.
  • a contact point 26 is punctiform in this area, due to the spherical shape of the permanent magnet 20.
  • FIG. 4 shows a representation of the profile rail system 1 from the direction IV according to FIG. 1 , In contrast to the representation according to the FIGS. 1 to 3 However, while the cover rail 5 is tilted about a longitudinal axis 27. The tilting of the cover rail 5 has no effect on the size of the contact point 25 Permanent magnet 20 is substantially independent of the tilting position of the cover rail 5.
  • the cover rail 5 may also have only a covering wing 15.
  • the profile rail system 1 is used as edge termination for a covering 3.
  • it is intended to provide 15 different length cover wings to compensate in this way larger height differences between adjacent pads 3 can this would be possible by tilting the cover rail 5 alone.
