Description

Die Erfindung betrifft einen Rost zur Bildung von Laufmatten oder Fußabstreifern, bei dem durch Querverbindungen auf Abstand voneinander gehaltene Längsstäbe aus formhartem Material mit Einsatzstreifen aus verformbarem Werkstoff, z.B. Borstenmaterial, Textilbelag, Filz, Nadelvlies, Gummi oder dergleichen, versehen sind, und bei dem die Einsatzstreifen mit ihrer die Trittfläche des Rostes bildenden Oberfläche über die Oberkante der Längsstäbe hinausragen.The invention relates to a grate for the formation of running mats or wipers, in which by transverse connections spaced longitudinal rods made of rigid material with insert strips made of deformable material, e.g. Bristle material, textile covering, felt, needle fleece, rubber or the like are provided, and in which the insert strips with their surface forming the tread surface of the grate protrude beyond the upper edge of the longitudinal bars.

Roste dieser Art sind bereits in verschiedenen Ausführungsformen bekannt, wie bspw. aus der EP-B 0 059 886 und auch aus der EP-B 0 125 618 hervorgeht.Gratings of this type are already known in various embodiments, as can be seen, for example, from EP-B 0 059 886 and also from EP-B 0 125 618.

Diese bekannten Roste haben sich im praktischen Einsatz als Laufmatten oder Fußabstreifer bestens bewährt, weil sie das sichere Abstreifen von verkrustetem Schmutz und Schnee gewährleisten, ohne daß ihre guten Säuberungseigenschaften beim Entfernen von Staub und Feuchtigkeit beeinträchtigt werden. Sie haben darüber hinaus den Vorteil, daß sie sich mit minimaler Bauhöhe erstellen lassen, trotzdem aber im Gebrauch eine großflächige und damit formstabile Abstützung gewährleisten sowie einen einfachen Zusammenbau sämtlicher Einzelteile, gewissermaßen nach dem Druckknopfsystem, ermöglichen.These known gratings have proven themselves in practical use as running mats or doormats because they ensure the reliable wiping off of encrusted dirt and snow without their good cleaning properties being impaired when removing dust and moisture. They also have the advantage that they can be created with a minimal overall height, but still ensure a large-area and therefore dimensionally stable support in use, and enable simple assembly of all individual parts, to a certain extent using the push-button system.

Mittlerweile hat sich im täglichen Gebrauch immer mehr die Benutzung von Schuhwerk mit stark eingekerbten Sohlen - Profilsohlen - gegenüber dem Schuhwerk mit glatten Sohlen durchgesetzt. Es kann davon ausgegangen werden, daß das Schuhwerk mit stark eingekerbten Sohlen zwischenzeitlich einen Anteil von über 70% erreicht hat, insbesondere weil Turnschuhe zum täglichen Gebrauchsgegenstand geworden sind, die nicht nur in der Freizeit, sondern auch beim Gang zur Arbeitsstelle und zur Schule ständig benutzt werden.In the meantime, the use of footwear with strongly indented soles - profiled soles - has increased in everyday use compared to footwear with smooth soles enforced. It can be assumed that footwear with strongly notched soles has now reached a share of over 70%, in particular because sneakers have become a daily commodity that is used not only in leisure time, but also when going to work and school will.

Mit solchem Schuhwerk wird jedoch der Straßenschmutz naturgemäß in verstärktem Maße in die Innenräume von Gebäuden, insbesondere in Betriebs-, Behörden- und Wohnbauten sowie Schulen, getragen.With such footwear, however, the street dirt is naturally carried to an increased extent into the interiors of buildings, in particular in company, government and residential buildings as well as schools.

Der aus der Benutzung solchen Schuhwerks resultierende, erhöhte Schmutzanfall in den Gebäuden kann durch die bisher bekanntgewordene Ausgestaltung der Roste zur Bildung von Laufmatten oder Fußabstreifern nur unbefriedigend beherrscht werden, weil die die Trittflächen der Roste bildenden verformbaren Werkstoffe nicht genügend tief in die Einkerbungen der Profilsohlen eindringen können, um die darin befindlichen Schmutzteile zu lösen und abzustreifen.The increased dirt accumulation in the buildings resulting from the use of such footwear can only be mastered unsatisfactorily by the previously known design of the grids for the formation of running mats or wipers, because the deformable materials forming the tread surfaces of the grates do not penetrate deep enough into the notches in the profile soles to loosen and wipe off the dirt particles inside.

Zur Beseitigung dieser beträchtlichen Unzulänglichkeiten zielt daher die Erfindung darauf ab, einen Rost zur Bildung von Laufmatten oder Fußabstreifern der anfangs spezifizierten Art so auszugestalten, daß er mindestens bereichsweise eine Trittfläche aus verformbarem Werkstoff aufweist, die auch beim Begehen mit stark eingekerbten Profilsohlen mit allen Stellen derselben, also auch mit den Begrenzungsflächen der Einkerbungen, in sicheren Abstreifkontakt kommen kann.In order to eliminate these considerable inadequacies, the invention therefore aims to design a grate for the formation of running mats or wipers of the type initially specified in such a way that it has, at least in some areas, a tread made of deformable material which, even when being walked on with strongly notched profile soles, has all parts of the same , ie also with the delimiting surfaces of the notches, can come into safe wiping contact.

Ausgehend von der Erkenntnis, daß Borstenmaterial am ehesten geeigent ist, auch die eingekerbten Bereiche von Profilsohlen zu erreichen und zu bestreichen, wird die der Erfindung zugrundeliegende Aufgabe durch die Kennzeichnungsmerkmale des Anspruchs 1, nämlich dadurch gelöst, daß in den mit Abstand voneinander gehaltenen Längsstäben mindestens ein, vorzugsweise aber mehrere, Borstenmaterial tragende Einsatzstreifen zwischen mit Filz-, Nadelvlies- und Textilbelag oder dergleichen ausgestatteten Auf- bzw. Einsatzstreifen angeordnet sind, daß das Borstenmaterial in den Auf- bzw. Einsatzstreifen in Borstenmaterial-Reihen und/oder -Bündeln vorgesehen ist, die jeweils Abstand voneinander haben, und daß die Borstenmaterial-Reihen und/oder -Bündel mit ihren freien Enden die Oberkantenebene der mit Filz-, Nadelvliesund Textilbelag oder dergleichen ausgestatteten Einsatzstreifen um ein vorgegebenes Mindestmaß überragen.Based on the knowledge that bristle material is most likely to also reach and coat the notched areas of profile soles, the object on which the invention is based is given by the characterizing features of claim 1, namely in that at least one, but preferably several, bristle-bearing insert strips are arranged between the felt strips, needled fleece and textile covering or the like in the spaced-apart longitudinal rods, that the bristle material is arranged in the Auf- or insert strips in bristle material rows and / or bundles is provided, which are spaced from each other, and that the bristle material rows and / or bundles with their free ends the top edge plane of the felt, needle fleece and textile covering or the like protrude equipped insert strips by a predetermined minimum dimension.

Es ist ohne weiteres einleuchtend, daß durch eine solche Ausgestaltung eines Rostes einerseits ein optimales Stabilitätsverhalten des Borstenmaterials gewährleistet wird, weil dieses bei den üblicherweise vorkommenden Belastungen nur innerhalb vorgegebener Grenzen und damit elastisch verformt werden aber nicht bleibend umknicken kann. Die Langzeit-Pinselfunktion des Borstenmaterials wird daher optimal erhalten.It is obvious that such a design of a grate on the one hand ensures optimum stability behavior of the bristle material, because it can only be elastically deformed under the normally occurring loads and therefore cannot deform permanently. The long-term brush function of the bristle material is therefore optimally preserved.

Andererseits wird aber gewährleistet, daß das erfindungsgemäß vorgesehene Borstenmaterial auch sicher in die Einkerbungsbereiche der Profilsohlen eindringt sowie den dort anhaftenden bzw. eingeklemmten Straßenschmutz löst und entfernt.On the other hand, however, it is ensured that the bristle material provided according to the invention also penetrates securely into the indentation areas of the profile soles and loosens and removes the road dirt adhering or pinched there.

Obwohl es besonders zweckmäßig ist, daß sowohl die das Borstenmaterial tragenden Einsatzstreifen als auch die mit Filz-, Nadelvlies- und Textilbelag oder dergleichen ausgestatteten Auf- bzw. Einsatzstreifen sich jeweils über die ganze Länge der sie aufnehmenden Längsstäbe erstrecken, besteht im Rahmen der Erfindung durchaus aber auch die Möglichkeit, in Längsrichtung ein und desselben Längsstabes bereichsweise abwechselnd Einsatzstreifen mit Borstenmaterial oder Auf- bzw. Einsatzstreifen mit Filz-, Nadelvlies-und Textilbelag oder dergleichen vorzusehen und diese dann an den einander benachbarten Längsstäben relativ zueinander längs versetzt anzuordnen.Although it is particularly expedient that both the insert strips carrying the bristle material and the attachment or insert strips equipped with felt, needle fleece and textile covering or the like each extend over the entire length of the longitudinal rods receiving them, the invention does indeed exist but also the possibility in the longitudinal direction of one and the same longitudinal bar to alternately provide insert strips with bristle material or top or insert strips with felt, needle fleece and textile coverings or the like and then arrange them longitudinally offset relative to one another on the adjacent longitudinal rods.

Es hat sich für den praktischen Gebrauch als besonders empfehlenswert herausgestellt, wenn erfindungsgemäß - nach Anspruch 2 - die freien Enden der Borstenmaterial-Reihen und/oder -Bündel die Oberkantenebene der mit Filz-, Nadelvlies- und Textilbelag oder dergleichen ausgestatteten Einsatzstreifen um ein Maß überragen, das etwa zwischen 3 und 5 mm liegt, dabei aber geringer ausgeführt ist, als das Maß, um welches die Oberkantenebene des unbelasteten Filz-, Nadelvlies- und Textilbelages oder dergleichen über die Oberkantenebene der aus formhartem Material bestehenden Längsstäbe hinausragt.It has turned out to be particularly advisable for practical use if, according to the invention - according to claim 2 - the free ends of the bristle material rows and / or bundles protrude by a measure the upper edge plane of the insert strips equipped with felt, needle fleece and textile covering or the like , which is approximately between 3 and 5 mm, but is made smaller than the amount by which the upper edge plane of the unloaded felt, needle fleece and textile covering or the like protrudes beyond the upper edge plane of the longitudinal rods made of rigid material.

Eine erfindungsgemäße Ausgestaltungsmöglichkeit der das Borstenmaterial tragenden Einsatzstreifen liegt - nach Anspruch 3 - darin, daß die das Borstenmaterial tragenden Auf-bzw. Einsatzstreifen einen mit den Längsstäben in Verbindung stehenden bzw. kuppelbaren, leistenförmigen Grundkörper aufweisen. Hierbei kann - gemäß Anspruch 4 - der leistenförmige Grundkörper eine in Querschnittsrichtung abgestufte Oberseite aufweisen und die Borstenmaterial-Reihen und/oder Borstenmaterial-Bündel können über die Oberseite sämtlicher Stufen des Grundkörpers mit wenigstens annähernd gleicher freier Länge vorstehen.An embodiment of the inventive insert strips carrying the bristle material lies - according to claim 3 - in that the mounting or carrying the bristle material. Insert strips have a strip-shaped base body which is connected to the longitudinal bars or can be coupled. Here, according to claim 4, the strip-shaped base body can have an upper side which is stepped in the cross-sectional direction, and the bristle material rows and / or bristle material bundles can protrude above the upper side of all the steps of the base body with at least approximately the same free length.

Nach einem Weiterbildungsmerkmal der Erfindung kann - nach Anspruch 5 - die Höhe der Stufen am Grundkörper zwischen 20 bis 30% der freien Länge des Borstenmaterials betragen und dabei vorzugsweise etwa 25% derselben entsprechen.According to a further development feature of the invention, the height of the steps on the base body can be between 20 and 30% of the free length of the bristle material and preferably correspond to about 25% of the same.

Wenn also in der Praxis die freie Länge der Borsten in allen Borstenmaterial-Reihen und/oder Borstenmaterial-Bündeln etwa auf 8 mm eingestellt wird, dann sollte die Höhe der einzelnen Stufen am Grundkörper etwa 2 mm betragen, so daß auch die freien Enden der Borstenmaterial-Reihen und/oder -Bündel im Bereich der verschiedenen Stufen in ihrer Höhenlage zueinander um etwa diese 2 mm differieren.So if in practice the free length of the bristles in all bristle material rows and / or bristle material bundles is set to approximately 8 mm, then the height of the individual steps on the base body should be approximately 2 mm, so that the free ends of the bristle material -Rows and / or -bundles in the area of the different levels differ in height by about these 2 mm.

Unter Ausnutzung der den einzelnen Borsten des Borstenmaterials innewohnenden Elastizität ergibt sich durch diese Ausgestaltung ein optimaler Abstreifer- und Reinigungseffekt an allen Stellen von Profilsohlen mit den heute üblichen Kerbformationen.Taking advantage of the elasticity inherent in the individual bristles of the bristle material, this configuration results in an optimal wiping and cleaning effect at all points of profile soles with the notch formations common today.

Eine erfindungsgemäße Ausgestaltungsmöglichkeit der das Borstenmaterial tragenden Einsatzstreifen liegt - nach Anspruch 6 - darin, daß jeder Grundkörper zwei Stufen aufweist und diese Stufen mit einer unterschiedlichen Anzahl von Borstenmaterial-Reihen besetzt sind. Hierbei kann -gemäß Anspruch 7 - die tiefer gelegene Stufe mit nur einer Borstenmaterial-Reihe, die höher gelegene Stufe aber mit mindestens zwei Borstenmaterial-Reihen ausgestattet sein.An embodiment of the inventive insert strips carrying the bristle material lies - according to claim 6 - in that each base body has two steps and these steps are occupied with a different number of rows of bristle material. According to claim 7, the lower step can be equipped with only one row of bristle material, but the higher step can be equipped with at least two rows of bristle material.

Andererseits liegt es jedoch auch im Rahmen der Erfindung, daß - nach Anspruch 8 - jeder Grundkörper drei Stufen aufweist, von denen die beiden äußeren etwa auf gleicher Höhe liegen. Dabei kann - nach Anspruch 9 - die mittlere Stufe des Grundkörpers höher liegen als dessen beide äußeren Stufen. Darüber hinaus ist - nach Anspruch 10 - empfehlenswert, daß jede Stufe mit der gleichen Anzahl von Borstenmaterial-Reihen versehen ist, bspw. - nach Anspruch 11 - jeweils mit nur einer Borstenmaterial-Reihe besetzt ist.On the other hand, it is also within the scope of the invention that - according to claim 8 - each base body has three steps, of which the two outer ones are approximately at the same height. It can - according to claim 9 - the middle step of the base body is higher than its two outer steps. In addition - according to claim 10 - it is recommended that each step is provided with the same number of rows of bristle material, for example - according to claim 11 - is occupied with only one row of bristle material.

Die Erfindung sieht - gemäß Anspruch 12 - weiterhin vor, daß die Grundkörper der Auf- bzw. Einsatzstreifen aus Kunststoff bestehen und dabei durch Strangpressen oder Spritzgießen gefertigt sind.The invention further provides - according to claim 12 - that the base body of the up or insert strips are made of plastic and are manufactured by extrusion or injection molding.

Während bei der Herstellung der Grundkörper durch Strangpressen die Löcher zur Aufnahme der einzelnen Borstenmaterial-Bündel mit einer geeigneten Bohrvorrichtung nachträglich hergestellt werden müssen, ist es bei der Herstellung der Grundkörper durch Spritzgießen möglich, alle diese Löcher bereits vorzufertigen, so daß nur ein zusätzlicher Arbeitsgang zur Fertigstellung der Auf- bzw. Einsatzstreifen, nämlich das Einsetzen und Befestigen der Borstenmaterial-Bündel erforderlich ist.While the holes for receiving the individual bristle material bundles have to be made subsequently with a suitable drilling device in the manufacture of the base bodies by extrusion, it is possible in the manufacture of the base bodies by injection molding to prefabricate all of these holes, so that only one additional operation is required Completion of the up or insert strips, namely the insertion and fastening of the bristle material bundle is required.

Es liegt weiterhin im Rahmen der Erfindung, daß - nach Anspruch 13 - jede Borstenmaterial-Reihe aus einer Vielzahl von in Löchern des Grundkörpers verankerten Borstenmaterial-Bündeln besteht, und daß dabei die Borstenmaterial-Bündel in benachbarten Borstenmaterial-Reihen von auf Lücke gegeneinander versetzt liegenden Löchern aufgenommen sind. Aufgrund dieser Maßnahmen wird der Reinigungseffekt der mit dem Borstenmaterial versehenen Auf- bzw. Einsatzstreifen optimiert.It is also within the scope of the invention that - according to claim 13 - each bristle material row consists of a plurality of bristle material bundles anchored in holes in the base body, and that the bristle material bundles in adjacent bristle material rows are offset from one another by a gap Holes are added. These measures optimize the cleaning effect of the application or insert strips provided with the bristle material.

Es hat sich für die Säuberung der rinnenartigen Vertiefung von Profilsohlen als besonders zweckmäßig erwiesen, wenn erfindungsgemäß - nach Anspruch 14 - die freien Enden der Borstenmaterial-Bündel verlängert sind und im Bereich der Verlängerungen kegelstumpfartig angespitzt oder schräg angeschnitten sind.It has proven to be particularly expedient for cleaning the channel-like depression of profile soles if, according to the invention - according to claim 14 - the free ends of the bristle material bundles are extended and are truncated in the region of the extensions or cut obliquely.

Obwohl auch grundsätzlich die Möglichkeit besteht, bei einem Rost zur Bildung von Laufmatten oder Fußabstreifern dessen durch Querverbindungen auf Abstand voneinander gehaltene Längsstäbe unmittelbar durch die Grundkörper der Auf- bzw. Einsatzstreifen zu bilden, wird für den praktischen Einsatz einer Bauart der Vorzug gegeben, bei welcher nach der Erfindung - gemäß Anspruch 15 - einerseits die Längsstäbe an ihrer Oberseite und andererseits die Grundkörper der Auf-bzw. Einsatzstreifen an ihrer Unterseite hinterschnitten profilierte Längsstege und Längsnuten aufweisen, die entweder in Längsrichtung formschlüssig ineinanderschiebbar oder quer zu ihrer Längsrichtung federelastisch miteinander verrastbar sind.Although there is also the possibility in principle of forming a grate to form running mats or wipers, the longitudinal bars, which are kept at a distance from one another by transverse connections, directly through the base body of the up or insert strips, preference is given to the practical use of a type in which According to the invention - according to claim 15 - on the one hand the longitudinal rods on their top and on the other hand the base body of the Auf- or. Insert strips have undercut profiled longitudinal webs and longitudinal grooves on their underside, which can either be positively pushed into one another in the longitudinal direction or can be latched to one another transversely to their longitudinal direction.

Im letztgenannten Falle besteht die vorteilhafte Möglichkeit, den zur Bildung von Laufmatten oder Fußabstreifern dienenden Rost jederzeit, also auch nachträglich noch, auf unterschiedliche Bedürfnisse abzustimmen, bspw. dadurch, daß die Lage unterschiedlich ausgestatteter Auf- bzw. Einsatzstreifen innerhalb des verlegten Rostfeldes bedarfsabhängig variiert wird.In the latter case, there is the advantageous possibility of adapting the grating used to form running mats or wipers to different needs at any time, that is to say later on, for example by changing the position of differently fitted application or insert strips within the installed grate field as required .

Erfindungsgemäß kann es sich darüber hinaus auch als wichtig erweisen, daß - nach Anspruch 16 - die Querverbindungen zwischen benachbarten Längsstäben aus Halteelementen bestehen, die hinterschnitten gestaltete Kopfteile aufweisen, mittels denen sie jeweils in eine hinterschnittene Nut an der Unterseite der Längsstäbe einrückbar sind, wobei sich zwei hinterschnittene Längsnuten an der Unterseite der Längsstäbe befinden und jeweils randseitig angeordnet sind. Die Halteelemente können dabei - nach Anspruch 17 - einen im wesentlichen U-förmigen Querschnitt haben, wobei jeder ihrer Flansche ein hinterschnitten gestaltetes Kopfteil trägt.According to the invention it can also prove important that - according to claim 16 - the cross connections between adjacent longitudinal bars consist of holding elements which have undercut shaped head parts, by means of which they can each be inserted into an undercut groove on the underside of the longitudinal bars, whereby two undercut longitudinal grooves on the underside of the Longitudinal bars are located and are each arranged on the edge. The holding elements can - according to claim 17 - have a substantially U-shaped cross section, each of its flanges carrying an undercut shaped head part.

In vielen Fällen ist es nach der Erfindung auch empfehlenswert, daß die Längsstäbe - nach Anspruch 18 - durch aufwärts gerichtete Flansche oder Leisten begrenzte Rinnen aufweisen, in denen die Einsatzstreifen zumindest über den größten Teil der Höhe ihrer Grundkörper aufgenommen sind.In many cases, it is also recommended according to the invention that the longitudinal bars - according to claim 18 - have channels delimited by upwardly directed flanges or strips, in which the insert strips are accommodated at least over most of the height of their base bodies.

Schließlich erweist es sich erfindungsgemäß auch als wichtig, daß - nach Anspruch 19 - mit Borstenmaterial bestückte Auf- bzw. Einsatzstreifen nur in vorbestimmbaren, begrenzten Bereichen der Rostfläche auf oder in den Längsstäben verankert sind, während in den übrigen Bereichen der Rostfläche die Längsstäbe Auf- bzw. Einsatzstreifen tragen, die mit anderem verformbaren Material, z.B. Textilbelag, Filz, Nadelvlies, Gummi oder dergleichen bestückt sind.Finally, it also proves to be important in accordance with the invention that - according to claim 19 - attachment or insert strips equipped with bristle material are anchored on or in the longitudinal bars only in predeterminable, limited areas of the grate surface, while in the remaining areas of the grate surface the longitudinal bars or wear strips that are covered with other deformable material, e.g. Textile covering, felt, needle fleece, rubber or the like are equipped.

Mit einer solchen Ausgestaltung von Rosten zur Bildung von Laufmatten oder Fußabstreifern kann - insbesondere bei einer genügend großen Bemessung der jeweiligen Schmutzschleuse - nicht nur eine Grob- und Feinreinigung, sondern darüber hinaus auch eine Vor- und Nachtrocknung der Schuhsohlen während des Begehens bewirkt werden. Es ist dabei vorteilhaft, wenn am Anfang des Auftritts einer solchen Schmutzschleuse eine Wechselkombination von mit Borstenmaterial und mit Nadelvlies oder dergleichen besetzten Längsstäben vorgesehen ist, wobei sich hieran die üblicherweise lediglich mit Nadelvlies oder Textilmaterial bestückten Abstreifleisten anschließen können.With such a design of grates to form running mats or wipers - especially with a sufficiently large dimensioning of the respective dirt lock - not only a rough and fine cleaning, but also a pre- and post-drying of the soles of the shoes can be effected during the walk. It is advantageous if, at the beginning of the appearance of such a dirt lock, an interchangeable combination of longitudinal rods covered with bristle material and needle fleece or the like is provided, which can be followed by the scraper strips usually only fitted with needle fleece or textile material.

Der Rost 1 nach Fig. 1 der Zeichnung besteht aus Längsstäben 2, die mit Abstand nebeneinander und mit ihren Längsachsen parallel zueinander liegend angeordnet sind. Dabei sind die Längsstäbe 2 durch quer zu ihnen gerichtete Halteelemente 3 miteinander verbunden und zugleich voneinander auf Abstand gehalten.The grate 1 according to FIG. 1 of the drawing consists of longitudinal bars 2, which are arranged at a distance next to one another and with their longitudinal axes lying parallel to one another. The longitudinal bars 2 are connected to one another by holding elements 3 directed transversely to them and at the same time are kept at a distance from one another.

Es ist ohne weiteres möglich, die Roste 1 als einstückiges Formteil aus Kunststoff, bspw. durch Spritzgießen, zu fertigen, so daß die Längsstäbe und die Halteelemente 3 einstückig miteinander in Verbindung stehen.It is readily possible to manufacture the grids 1 as a one-piece molded part made of plastic, for example by injection molding, so that the longitudinal bars and the holding elements 3 are connected to one another in one piece.

Vorzugsweise werden jedoch die Längsstäbe 2 durch Strangpressen bzw. Extrudieren hergestellt und können dabei aus Metall oder Kunststoff bestehen. Bewährt hat es sich besonders, die Längsstäbe 2 aus formhartem Kunststoff zu fertigen.However, the longitudinal bars 2 are preferably produced by extrusion or extrusion and can consist of metal or plastic. It has proven particularly useful to manufacture the longitudinal bars 2 from rigid plastic.

Auch die Halteelemente 3 können in diesem Falle von einem durch Strangpressen oder Extrudieren gefertigten Schienenprofil in geeigneter Breite abgetrennt werden, wobei auch dieses zur Herstellung der Halteelemente 3 dienende Schienenprofil aus Metall oder Kunststoff, vorzugsweise aus formhartem Kunststoff, bestehen kann. Die Längsstäbe 2 haben beim Ausführungsbeispiel nach den Fig. 1 und 2 einen im wesentlichen U-förmigen Querschnitt, d.h. sie weisen jeweils zwei Flansche 4' und 4" auf, die durch einen Steg 5 einstückig miteinander in Verbindung stehen.The holding elements 3 can also be separated in this case from a rail profile made by extrusion or extrusion in a suitable width, and this rail profile used to produce the holding elements 3 can also consist of metal or plastic, preferably of rigid plastic. The longitudinal bars 2 in the embodiment according to FIGS. 1 and 2 have a substantially U-shaped cross section, i.e. they each have two flanges 4 'and 4 "which are integrally connected to one another by a web 5.

Zwischen den beiden Flanschen 4' und 4" und dem Steg 5 begrenzen die Längsstäbe 2 eine nach oben offene Nut 6, die mit Abstand oberhalb des Steges zwei Absätze 6', 6" hat, an die sich eine zum Steg 5 hin zunächst trapezförmig verengende und dann wieder trapezförmig erweiterende Vertiefung 7 anschließt.Between the two flanges 4 'and 4 "and the web 5, the longitudinal bars 2 delimit an upwardly open groove 6, which has two shoulders 6', 6" at a distance above the web, to which one initially narrows trapezoidally towards the web 5 and then again connecting trapezoidal widening 7.

Von der Längsmitte des Steges 5 ragt in die Vertiefung eine hinterschnitten profilierte Wulst 8 hoch, die mit geringfügigem Abstand unterhalb der Absätze 6', 6" endet. Die Längsstäbe 2 sind insgesamt zu ihrer Längsmittelebene 9-9 symmetrisch profiliert und von der Unterseite her sind jeweils zwei relativ schmale, also schlitzartige Nuten 10', 10" eingeformt. Dabei liegen auch diese Nuten 10' und 10" symmetrisch zur Längsmittelebene 9-9 und sind randseitig im Anschluß an eine mit der Innenfläche der Flansche 4' und 4" zusammenfallenden Vertikalebene angeordnet.An undercut profiled bead 8 protrudes into the recess from the longitudinal center of the web 5 and ends at a slight distance below the shoulders 6 ', 6 ". The longitudinal bars 2 are profiled symmetrically overall with respect to their longitudinal center plane 9-9 and are from the underside two relatively narrow, ie slot-like grooves 10 ', 10 "are formed in each case. These grooves 10 'and 10 "are also symmetrical to the longitudinal center plane 9-9 and are arranged on the edge side in connection with a vertical plane coinciding with the inner surface of the flanges 4' and 4".

Jede der beiden schlitzartigen Nuten 10', 10" geht dabei in eine nach oben gerichtete, pfeilspitzenartige Erweiterung 11' und 11" über, so daß in jeder Nut 10', 10" zwei Hinterschneidungen begrenzt werden.Each of the two slot-like grooves 10 ', 10 "merges into an upward, arrowhead-like extension 11' and 11", so that two undercuts are delimited in each groove 10 ', 10 ".

Die außenseitige Begrenzung der Nuten 10', 10" besteht aus einem einstückig angeformten Hakenprofil, dessen einwärts gerichteter Hakenansatz 12' bzw. 12" mit seiner Unterseite etwa auf gleicher Höhe mit der Oberseite des Steges 5 liegt.The outer boundary of the grooves 10 ', 10 "consists of a one-piece molded hook profile, the inward-facing hook shoulder 12' or 12" of which lies at approximately the same level with the top of the web 5 with its underside.

Die Halteelemente 3, mittels denen die Längsstäbe 2 zum Rost 1 verbunden werden können, haben einen im wesentlichen U-förmigen Querschnitt. Jeder ihrer beiden Flansche 13' und 13" wird dabei von zwei zueinander spiegelbildlichen Hakenstegen 14' und 14" gebildet, welche vom Profilsteg 15 hochragen. Zwischen den einander zugewendeten Rückenflächen der beiden Hakenstege 14' und 14" ist jeweils ein Abstandsspalt 16 gebildet.The holding elements 3, by means of which the longitudinal bars 2 can be connected to form the grate 1, have an essentially U-shaped cross section. Each of its two flanges 13 'and 13 "is formed by two mutually mirror-image hook webs 14' and 14" which protrude from the profile web 15. A spacing gap 16 is formed in each case between the mutually facing back surfaces of the two hook webs 14 'and 14 ".

Die freien Enden der beiden jeweils zu einem der Flansche 13' und 13" gehörenden Hakenstege 14' und 14" begrenzen miteinander einen nach oben etwa pfeilspitzenförmigen Querschnitt, welcher dem Querschnitt der pfeilspitzenförmigen Erweiterungen 11' und 11" an den Längsstäben 2 angepaßt ist.The free ends of the two hook webs 14 'and 14 "each belonging to one of the flanges 13' and 13" delimit an upward, approximately arrowhead-shaped cross section, which is adapted to the cross section of the arrowhead-shaped extensions 11 'and 11 "on the longitudinal bars 2.

Der Profilsteg 15 der Halteelemente 3 hat eine Dicke, die der Dicke des Steges 5 an den Längsstäben 2 entspricht.The profile web 15 of the holding elements 3 has a thickness which corresponds to the thickness of the web 5 on the longitudinal bars 2.

Beim Zusammenbau des Rostes 1 werden die Halteelemente 3 einfach mit Hilfe ihrer jeweils von den Hakenstegen 14' und 14" gebildeten Flanschen 13' und 13" druckknopfartig in die Nuten 10' und 10" an der Unterseite der Längsstäbe 2 eingedrückt, so daß sie jeweils formschlüssig in die hinterschnittenen Erweiterungen 11', 11" einrasten. Dabei kommen dann die Profilstege 15 der Halteelemente 3 auf gleicher Ebene mit den Stegen 5 der Längsstäbe 2 zu liegen, und zwar in der Weise, daß am fertigen Rost 1 die Längsstäbe 2 und die sie miteinander kuppelnden Halteelemente 3 eine gemeinsame, großflächige Auflageebene haben, wie das deutlich die Fig. 2 erkennen läßt.When assembling the grate 1, the holding elements 3 are simply pressed into the grooves 10 'and 10 "on the underside of the longitudinal rods 2 with the aid of their flanges 13' and 13" formed by the respective hook webs 14 'and 14 ", so that they each snap into the undercut extensions 11 ', 11 ". Here Then the profile webs 15 of the holding elements 3 come to lie on the same level with the webs 5 of the longitudinal bars 2, in such a way that the longitudinal bars 2 and the holding elements 3 coupling them together have a common, large-area support plane on the finished grate 1, such as that clearly shows Fig. 2.

Die zur Oberseite des Rostes 1 hin offenen Nuten 6 der Längsstäbe 2 dienen zur Aufnahme von Einsatzstreifen 17, deren Oberfläche am fertigen Rost 1 die begehbare Trittfläche bilden. Zu diesem Zweck werden die Einsatzstreifen 17 so in die Nut 6 der Längsstäbe 2 eingesetzt, daß sie mit ihrer die Trittfläche des Rostes 1 bildenden Oberfläche über die Oberkante der Flansche 4' und 4" hinausragen.The open to the top of the grate 1 grooves 6 of the longitudinal bars 2 serve to receive insert strips 17, the surface of which forms the walkable step surface on the finished grate 1. For this purpose, the insert strips 17 are inserted into the groove 6 of the longitudinal bars 2 in such a way that their surface, which forms the tread surface of the grate 1, projects beyond the upper edge of the flanges 4 'and 4 ".

Die Einsatzstreifen 17 können eine unterschiedliche Auslegung erhalten. Während bspw. nach den Fig. 1 und 2 jeweils die Einsatzstreifen 17' in einer im Querschnitt etwa U-förmigen Halteschiene 18 eine auf einer Grund- bzw. Stützschicht 19 sitzende Nadelvliesschicht 20 tragen, weisen die Einsatzstreifen 17" einen mit Borstenmaterial 21 bestückten, leistenförmigen Grundkörper 22 auf.The insert strips 17 can have a different design. While, for example, according to FIGS. 1 and 2, the insert strips 17 'each have a needle-fleece layer 20 seated on a base or support layer 19 in an approximately U-shaped holding rail 18, the insert strips 17 "have a bristle material 21, strip-shaped base body 22.

Jeder der Grundkörper 22 kann aus Kunststoff bestehen und dabei durch Strangpressen oder Spritzgießen gefertigt werden.Each of the base bodies 22 can consist of plastic and can be manufactured by extrusion or injection molding.

Während der Grundkörper 22 mit seinem Querschnittsprofil weitestgehend in die Nut 6 der Längsstäbe 2 paßt, wie dies die Fig. 2 erkennen läßt, weist er eine abgestufte Oberseite auf. Dabei können die Grundkörper 22 bspw. mit zwei Stufen 23' und 23" versehen sein, von denen die Stufe 23' etwa mit der oberen Endkante der Flansche 4' bzw. 4" der Längsstäbe 2 abschließt, während die Stufe 23' gegenüber diesen Endkanten um ein Maß von mehreren Millimetern höher liegt.While the base body 22 with its cross-sectional profile largely fits into the groove 6 of the longitudinal bars 2, as can be seen in FIG. 2, it has a stepped upper side. The base body 22 can be provided, for example, with two steps 23 'and 23 ", of which the step 23' terminates approximately with the upper end edge of the flanges 4 'or 4" of the longitudinal bars 2, while the step 23' opposite these end edges is several millimeters higher.

Die Breite der Stufe 23' entspricht etwa einem Drittel der Gesamtbreite des Grundkörpers 22, während die Stufe 23" eine Breite hat, die gleich zwei Dritteln der Gesamtbreite des Grundkörpers 22 ist.The width of the step 23 ′ corresponds to approximately one third of the total width of the base body 22, while the step 23 ″ has a width that is equal to two thirds of the total width of the base body 22.

Im Bereich der Stufe 23' trägt dabei der Grundkörper 22 jeweils eine Borstenmaterial-Reihe 21', während die Stufe 23" mit zwei solcher Borstenmaterial-Reihen 21' besetzt ist.In the area of step 23 ', base body 22 carries a row of bristle material 21', while step 23 "is occupied by two such rows of bristle material 21 '.

Jede einzelne Borstenmaterial-Reihe 21' wird dabei durch eine Vielzahl von Borstenmaterial-Bündeln 21'' gebildet, wie das deutlich in Fig. 1 zu sehen ist.Each individual bristle material row 21 'is formed by a plurality of bristle material bundles 21' ', as can be clearly seen in FIG. 1.

Sowohl aus Fig. 1 als auch aus Fig. 2 geht hervor, daß die Grundkörper 22 der Einsatzstreifen 17" an ihrer Oberseite auch zwei auf gleicher Höhe liegende Stufen 24' aufweisen können, zwischen denen eine höhergelegene Stufe 24" ausgebildet ist.Both from FIG. 1 and from FIG. 2 it can be seen that the base bodies 22 of the insert strips 17 "on their upper side can also have two steps 24 'at the same height, between which a higher step 24" is formed.

In diesem Falle entspricht die Breite jeder einzelnen der Stufen 24' und 24" etwa einem Drittel der Gesamtbreite des Grundkörpers 22 und jede dieser Stufen 24' und 24" ist mit nur einer Borstenmaterial-Reihe 21' besetzt.In this case, the width of each of the steps 24 'and 24 "corresponds to about a third of the total width of the base body 22 and each of these steps 24' and 24" is occupied by only one row of bristle material 21 '.

In jedem Falle ist die freie Borstenlänge aller Borstenmaterial-Reihen 21' und/oder Borstenmaterial-Bündel 21" übereinstimmend ausgelegt, wie das der Fig. 2 deutlich zu entnehmen ist. Hierdurch wird erreicht, daß die im Bereich der niedrigen Stufe 23' bzw. 24' der Grundkörper 22 angeordneten Borstenmaterial-Reihen 21' bzw. Borstenmaterial-Bündel 21" mit ihren freien Enden um ein Maß 25 gegenüber den freien Enden der Borstenmaterial-Reihen 21' bzw. Borstenmaterial-Bündel 21" auf den höhergelegenen Stufen 23" bzw. 24" zurückliegt, welches etwa der Höhendifferenz zwischen den Stufen 23' und 23" bzw. 24' und 24" entspricht.In any case, the free bristle length of all rows of bristle material 21 ′ and / or bristle material bundle 21 ″ is designed to match, as can be clearly seen in FIG. 2. This ensures that the area 23 ′ or 24 'of the base body 22 arranged bristle material rows 21' or bristle material bundles 21 "with their free ends by a dimension 25 compared to the free ends of the bristle material rows 21 'or bristle material bundles 21 "on the higher levels 23" or 24 ", which corresponds approximately to the height difference between levels 23 'and 23" or 24' and 24 ".

Bewährt hat es sich in der Praxis, die freie Länge der Borstenmaterial-Reihen 21' bzw. Borstenmaterial-Bündel 21" in einem Bereich zwischen 6 und 10 mm vorzusehen, bspw. auf 8 mm zu bemessen. Die Höhendifferenz zwischen den Stufen 23' und 23" bzw. 24' und 24" der Grundkörper 22 sollte dabei zwischen 1,5 und 2,5 mm betragen, vorzugsweise auf etwa 2 mm gelegt werden.It has proven useful in practice to provide the free length of the bristle material rows 21 'or bristle material bundles 21 "in a range between 6 and 10 mm, for example to 8 mm. The height difference between the steps 23' and 23 "or 24 'and 24" of the base body 22 should be between 1.5 and 2.5 mm, preferably about 2 mm.

Damit sämtliche Einsatzstreifen 17, also sowohl die Einsatzstreifen 17' als auch die Einsatzstreifen 17" funktionssicher in den Nuten 6 der Längsstäbe 2 festgelegt werden können, sich trotzdem aber bei Bedarf, bspw. zum Zwecke des Austauschs, relativ leicht hieraus lösen lassen, sind besondere Vorkehrungen getroffen. Sowohl die U-förmigen Halteschienen 18 der Einsatzstreifen 17' als auch die Grundkörper 22 der Einsatzstreifen 17" sind zu diesem Zweck mit angeformten Ansätzen 26 versehen, die eine hinterschnitten eingeformte Längsnut 27 enthalten. Über die Ansätze 26 mit der Längsnut 27 können dabei die Halteschienen 18 bzw. die Grundkörper 22 entweder in Längsrichtung formschlüssig auf die hinterschnittenen Wulste 8 am Steg 5 der Längsstäbe 2 aufgeschoben werden, oder aber sie werden quer zu ihrer Längsrichtung nach Art einer Schnapp-Rast-Vorrichtung auf die Wulste 8 aufgeklipst.So that all of the insert strips 17, that is to say both the insert strips 17 'and the insert strips 17 "can be securely fixed in the grooves 6 of the longitudinal bars 2, but can nevertheless be removed relatively easily if necessary, for example for the purpose of replacement, are special For this purpose, both the U-shaped holding rails 18 of the insert strips 17 'and the base body 22 of the insert strips 17 "are provided with molded-on projections 26 which contain an undercut formed longitudinal groove 27. About the approaches 26 with the longitudinal groove 27, the holding rails 18 or the base body 22 can either be pushed positively in the longitudinal direction on the undercut beads 8 on the web 5 of the longitudinal bars 2, or they are transversely to their longitudinal direction in the manner of a snap-lock -Device clipped onto the beads 8.

Das in Fig. 3 dargestellte Ausführungsbeispiel eines Rostes 1 zur Bildung von Laufmatten oder Fußabstreifern unterscheidet sich von demjenigen nach den Fig. 1 und 2 praktisch nur dadurch, daß Längsstäbe 2 in Benutzung genommen sind, die keine aufwärts gerichteten Flansche 4' und 4" aufweisen, so daß sie eine relativ flache Gestalt haben. Wie aus den Grundkörpern 22 und den Borstenmaterial-Reihen 21' bzw. Borstenmaterial-Bündeln 21" bestehenden Elemente 17" sind dabei nicht als Einsatzstreifen, sondern vielmehr als Aufsatzstreifen gestaltet, die sich bei vorgegebener Breitenabmessung der relativ flachen Längsstäbe 2 unmittelbar auf diese aufsetzen lassen und sich mit ihrem Querschnittsprofil über die Gesamtbreite derselben erstrecken können.The embodiment of a grate 1 shown in FIG. 3 for the formation of running mats or wipers differs from that according to FIGS. 1 and 2 practically only in that longitudinal bars 2 are used which have no upward flanges 4 'and 4 " , so that they have a relatively flat shape Base bodies 22 and the bristle material rows 21 'or bristle material bundles 21 "existing elements 17" are not designed as insert strips, but rather as attachment strips, which can be placed directly on these with a predetermined width dimension of the relatively flat longitudinal rods 2 and can be attached to them their cross-sectional profile can extend over the entire width thereof.

Da bei vorgegebener Breite der Längsstäbe 2 in diesem Falle die Aufsatzstreifen 17" eine größere Gesamtbreite haben, besteht im Bedarfsfalle die Möglichkeit, entweder den Borstenmaterial-Bündeln 21" im Bereich der verschiedenen Stufen 23', 23" bzw. 24', 24" einen größeren Gesamtdurchmesser zu geben, oder aber die Anzahl der vorgesehenen Oberflächenstufen und damit auch die Anzahl der auf einem Grundkörper 22 befindlichen Borstenmaterial-Reihen 21' zu erhöhen. In Fig. 4 ist noch zu sehen, wie vorteilhafterweise die Löcher 28 zur Aufnahme der Borstenmaterial-Bündel in den Grundkörpern 22 vorgesehen werden. Dabei ist erkennbar, daß die Löcher 28 in den einander benachbarten Reihen in Längsrichtung jeweils auf Lücke gegeneinander versetzt angeordnet sind, so daß die Wirkung der in ihnen aufgenommenen Borstenmaterial-Bündel 21" optimiert wird.Since in this case the attachment strips 17 "have a larger overall width for a given width of the longitudinal bars 2, if necessary there is the option of either bundling the bristle material bundles 21" in the area of the various steps 23 ', 23 "or 24', 24" to give larger overall diameter, or to increase the number of surface steps provided and thus also the number of rows of bristles 21 'located on a base body 22. 4 shows how the holes 28 for receiving the bristle material bundles in the base bodies 22 are advantageously provided. It can be seen that the holes 28 in the rows adjacent to one another are each offset in the longitudinal direction with a gap from one another, so that the effect of the bristle material bundles 21 ″ received in them is optimized.

Der Rost 1 nach Fig. 5 der Zeichnung entspricht in seiner grundsätzlichen Ausgestaltung dem Rost 1 nach den Fig. 1 und 2.The grate 1 according to FIG. 5 of the drawing corresponds in its basic configuration to the grate 1 according to FIGS. 1 and 2.

Jeder der Längsstäbe 2 des Rostes 1 nach Fig. 5 hat eine zur Oberseite hin offene Nut 6, die zur Aufnahme von Einsatzstreifen 17 dient, deren Oberfläche wiederum die begehbare Trittfläche des fertigen Rostes 1 bildet, welche insgesamt oberhalb der Oberkanten der Flansche 4' und 4" der Längsstäbe 2 liegt.Each of the longitudinal bars 2 of the grate 1 according to FIG. 5 has a groove 6 which is open towards the top and which serves to receive insert strips 17, the surface of which in turn forms the walkable tread of the finished grate 1, which overall is above the upper edges of the flanges 4 'and 4 "of the longitudinal bars 2 lies.

Auch beim Rost nach Fig. 5 sind jeweils Einsatzstreifen 17' in einer im Querschnitt etwa U-förmigen Halteschiene 18 angeordnet, wobei sie eine auf einer Grund- bzw. Stützschicht 19 sitzende Nadelvliesschicht 20 tragen. Ein solchermaßen ausgelegter Einsatzstreifen 17' ist dabei jeweils in den beiden äußeren Längsstäben 2 des Rostabschnitts nach Fig. 5 angeordnet.5, insert strips 17 'are each arranged in a holding rail 18 which is approximately U-shaped in cross section, with a needle fleece layer 20 seated on a base or support layer 19. An insert strip 17 'designed in this way is arranged in each of the two outer longitudinal bars 2 of the grate section according to FIG. 5.

Die drei dazwischen angeordneten Längsstäbe 2 sind hingegen mit Einsatzstreifen 17" besetzt, die einen mit Borstenmaterial 21 bestückten, leistenförmigen Grundkörper 22 aufweisen.The three longitudinal rods 2 arranged between them, on the other hand, are equipped with insert strips 17 ″ which have a strip-shaped base body 22 which is equipped with bristle material 21.

Auch nach Fig. 5 kann jeder Grundkörper 22 aus Kunststoff bestehen und dabei durch Strangpressen oder Spritzgießen hergestellt sein.5, each base body 22 can consist of plastic and can be produced by extrusion or injection molding.

Im Unterschied zu dem Grundkörper 22 nach den Fig. 1 bis 4 weisen die Grundkörper 22 nach Fig. 5 keine abgestufte Oberseite auf.In contrast to the base body 22 according to FIGS. 1 to 4, the base body 22 according to FIG. 5 has no stepped upper side.

Der Grundkörper 22 des linken Einsatzstreifens 17" paßt mit seinem Querschnittsprofil nicht vollständig in die Nut 6 des Längsstabes 2. Vielmehr ist er in seiner Dicke so bemessen, daß er die Oberkanten der beiden Flansche 4' und 4" um ein gewisses Maß, bspw. um 2 mm überragt.The base body 22 of the left-hand insert strip 17 "does not completely fit into the groove 6 of the longitudinal rod 2 with its cross-sectional profile. Rather, it is dimensioned in such a thickness that it overlaps the upper edges of the two flanges 4 'and 4" to a certain extent, for example. protrudes by 2 mm.

Der mittlere Einsatzstreifen 17" nach Fig. 5 ist hingegen mit einem Grundkörper 22 ausgestattet, dessen Querschnittsprofil so bemessen ist, daß seine Oberseite bündig mit den Endkanten der beiden Flansche 4' und 4" des betreffenden Längsstabes 2 abschließt.The middle insert strip 17 "according to FIG. 5, on the other hand, is equipped with a base body 22, the cross-sectional profile of which is dimensioned such that its upper side is flush with the end edges of the two flanges 4 'and 4" of the longitudinal rod 2 concerned.

Der in Fig. 5 rechts dargestellte Einsatzstreifen 17" hat schließlich ein Querschnittsprofil mit geneigter Oberseite, und zwar dergestalt, daß diese Oberseite bspw. mit der Endkante des linken Flansches 4' am Längsstab 2 bündig abschließt, während sie die Endkante des rechten Flansches 4" um ein gewisses Maß, bspw. um 2 mm, nach oben überragt.The insert strip 17 "shown on the right in FIG. 5 finally has a cross-sectional profile with an inclined upper side, in such a way that this upper side is flush with the end edge of the left flange 4 'on the longitudinal rod 2, while it is the end edge of the right flange 4" by a certain amount, e.g. by 2 mm, protrudes upwards.

Jeder Einsatzstreifen 17" ist mit Borstenmaterial 21 bestückt, welches in mehreren, bspw. jeweils drei, zueinander parallelen Borstenmaterial-Reihen 21' besteht. Jede dieser Borstenmaterial-Reihen 21' wird dabei durch eine Vielzahl von Borstenmaterial-Bündeln 21" gebildet, welche im Abstand voneinander in Löcher 28 eingesetzt sind, welche sich in der Oberseite des Grundkörpers 22 befinden.Each insert strip 17 "is equipped with bristle material 21, which consists of several, for example three, parallel bristle material rows 21 '. Each of these bristle material rows 21' is formed by a plurality of bristle material bundles 21", which in the Distance from each other are inserted in holes 28, which are located in the top of the base body 22.

Ein wichtiges Ausgestaltungskriterium des Rostes 1 nach Fig. 5 besteht darin, daß die freien Enden des Borstenmaterials 21 sämtlicher Borstenmaterial-Reihen 21' und -Bündel 21" auf einer gemeinsamen Horizontalebene 29-29 liegen, die sich mit Abstand 31 über einer Horizontalebene 30-30 befindet, welche die Oberkantenebene der Nadelvliesschicht 20 an den Einsatzstreifen 17' bildet.An important design criterion of the grate 1 according to FIG. 5 is that the free ends of the bristle material 21 of all rows of bristle material 21 'and bundle 21 "lie on a common horizontal plane 29-29, which is at a distance 31 above a horizontal plane 30- 30 is located, which forms the upper edge plane of the needle fleece layer 20 on the insert strips 17 '.

Die Oberkantenebene 30-30 der die Nadelvliesschicht 20 aufweisenden Einsatzstreifen 17' des Rostes 1 wird also von dem Borstenmaterial der Einsatzstreifen 17" in jedem Falle um das Maß 31 überragt.In any case, the bristle material of the insert strips 17 ″ projects beyond the upper edge plane 30-30 of the insert strips 17 ′ of the grate 1 having the needle fleece layer 20 by the dimension 31.

Erkennbar ist aus Fig. 5, daß am linken und am mittleren Einsatzstreifen 17" das Borstenmaterial 21 aller drei Borstenmaterial-Reihen 21' jeweils übereinstimmende Länge hat. Dabei ist jedoch die Länge des Borstenmaterials 21 am mittleren Einsatzstreifen 17" etwas länger bemessen, als am linken Einsatzstreifen 17", weil dort die Oberfläche des Grundkörpers 22 mit den Endkanten der Flansche 4' und 4" abschließt, während beim linken Einsatzstreifen 17" die Oberseite des Grundkörpers 22 die Endkanten dieser Flansche 4' und 4" überragt.It can be seen from FIG. 5 that the bristle material 21 of all three bristle material rows 21 'has the same length on the left and on the middle insert strip 17 ". However, the length of the bristle material 21 on the middle insert strip 17" is dimensioned somewhat longer than on left insert strip 17 "because there the surface of the base body 22 with the end edges of the flanges 4 'and 4" closes, while in the left insert strip 17 "the top of the base body 22 projects beyond the end edges of these flanges 4 'and 4".

Beim rechten Einsatzstreifen 17" hat das Borstenmaterial 21 in den drei Borstenmaterial-Reihen 21' jeweils eine unterschiedliche, freie Länge, weil dort die Oberfläche des Grundkörpers 22 in Querschnittsrichtung eine Neigungslage hat. Die größte freie Länge hat das Borstenmaterial 21 dabei in der linken Borstenmaterial-Reihe 21', während es die geringste freie Länge im Bereich der rechten Borstenmaterial-Reihe 21' aufweist.In the case of the right insert strip 17 ″, the bristle material 21 in the three rows of bristle material 21 ′ each has a different, free length, because there the surface of the base body 22 has an inclined position in the cross-sectional direction. The bristle material 21 has the greatest free length in the left bristle material Row 21 ', while it has the smallest free length in the area of the right row of bristle material 21'.

Selbstverständlich wären auch noch andere Ausgestaltungsmöglichkeiten für die Grundkörper 22 gegeben, wenn es darauf ankommt, unterschiedliche freie Längen des Borstenmaterials 21 in den verschiedenen Borstenmaterial-Reihen 21' zu erhalten. So könnte die Oberfläche der Grundkörper 22 eine konkave Wölbungsform in Querschnittsrichtung haben, wenn das Borstenmaterial 21 in der mittleren Borstenmaterial-Reihe 21' eine größere freie Länge erhalten soll, als in den äußeren Borstenmaterial-Reihen 21. Bei konvex gewölbter Oberfläche ergibt sich hingegen die geringste freie Länge für das Borstenmaterial 21 in der mittleren Borstenmaterial-Reihe, während die beiden äußeren Borstenmaterial-Reihen dann die größere freie Länge des Borstenmaterials 21 haben.Of course, there would also be other design options for the base body 22 if it is important to obtain different free lengths of the bristle material 21 in the different rows of bristle material 21 '. For example, the surface of the base body 22 could have a concave curvature in the cross-sectional direction if the bristle material 21 in the middle row of bristle material 21 'is to have a greater free length than in the outer row of bristle material 21. On the other hand, this results in a convexly curved surface smallest free length for the bristle material 21 in the middle row of bristle material, while the two outer rows of bristle material then have the greater free length of the bristle material 21.

Wichtig ist bei dem Rost 1 in der Ausführungsform nach Fig. 5 in jedem Falle, daß das Abstandsmaß 31 zwischen den beiden parallelen Ebenen 29-29 und 30-30 so bemessen ist, daß nur eine elastische Verformung des Borstenmaterials 21 in den Borstenmaterial-Reihen 21' und den Borstenmaterial-Bündeln 21" stattfinden kann, bis die Schuhsohlen ihre feste Stützauflage auf der Nadelvliesschicht 20 der Einsatzstreifen 17' erhalten.It is important in the case of the grate 1 in the embodiment according to FIG. 5 that the distance dimension 31 between the two parallel planes 29-29 and 30-30 is dimensioned such that only an elastic deformation of the bristle material 21 in the rows of bristle material 21 'and the bristle material bundles 21 "can take place until the soles of the shoes receive their firm support on the needle fleece layer 20 of the insert strips 17'.

In der Praxis hat sich auch das in Fig. 6 dargestellte Ausführungsbeispiel bewährt, bei dem die Borstenmaterial-Bündel 21" verlängert sind, um im Bereich der rinnenartigen Vertiefungen von Profilsohlen in jeder Richtung wirksam werden zu können. Die freien Enden können im Abschnitt der Verlängerung bspw. kegelstumpfartig angespitzt oder schräg angeschnitten sein. Dabei ist die höhere Stufe 23" zweckmäßigerweise mit schräg angeschnittenen, die tiefer gelegene Stufe 23' mit kegelstumpfartig angespitzten Borstenmaterial-Bündeln 21" bestückt, wobei die Borstenmaterial-Bündel 21" der niedrigen Stufe 23' mit ihren freien Enden um ein Maß 25 gegenüber den freien Enden der Borstenmaterial-Bündel 21" auf der höher gelegenen Stufe 23" zurückliegen, welches etwa der Höhendifferenz zwischen den Stufen 23' und 23" entspricht. Diese Anordnung gewährleistet ein gleichzeitiges Säubern der rinnenartigen Vertiefung von Profilsohlen sowie der gegensätzlich ausgebildeten Profilstäbe.6, in which the bristle material bundles 21 "are extended in order to be able to act in any direction in the region of the groove-like depressions of profile soles. The free ends can be in the section of the extension For example, the higher step 23 "is expediently equipped with obliquely cut bristle material bundles 21", the lower step 23 'with tapered bristle material bundles 21 ", with the bristle material bundles 21" of the lower step 23' their free ends by an amount 25 compared to the free ends of the bristle material bundles 21 "on the higher step 23", which corresponds approximately to the height difference between the steps 23 'and 23 ". This arrangement ensures simultaneous cleaning of the channel-like depression of Tread soles and the oppositely trained treads be.

An den Grundkörpern 22 der mit Borstenmaterial 21 bestückten Einsatzstreifen 17" ist noch zu sehen, daß die die Längsnut 27 begrenzenden Ansätze 26 zur Erzielung einer höchstmöglichen Elastizität in ihrem Übergangsbereich zum Grundkörper 22 durch eingeformte Längsnuten 32 begrenzt sind, die den wünschenswerten Schnapp-Rast-Effekt an den Wulsten 8 der Längsstäbe 2 unter Vermeidung einer Bruchgefahr wesentlich verbessern.On the base bodies 22 of the insert strips 17 ″ equipped with bristle material 21, it can also be seen that the lugs 26 delimiting the longitudinal groove 27 are delimited in their transition region to the base body 22 by molded-in longitudinal grooves 32 which achieve the desirable snap-lock latches in order to achieve the greatest possible elasticity. Improve the effect on the beads 8 of the longitudinal bars 2 significantly while avoiding the risk of breakage.

Bewährt hat es sich, wenn der Abstand 31 zwischen den beiden Ebenen 29-29 und 30-30 etwa zwischen 3 und 5 mm beträgt, so daß das Borstenmaterial 21 die Nadelvliesschicht 20 höchstens um dieses relativ geringe Maß überragen kann.It has proven useful if the distance 31 between the two planes 29-29 and 30-30 is approximately between 3 and 5 mm, so that the bristle material 21 can project beyond the needle fleece layer 20 at most by this relatively small amount.

Aus Fig. 4 geht noch hervor, daß sich die Grundkörper 22 der Einsatzstreifen 17" als Spritzgußformteile aus Kunststoff in vorgegebener Länge fertigen lassen, wobei die Stoßflächen der jeweils benachbart aneinanderstoßenden Formteile gewissermaßen mit einer Trapezverzahnung ineinandergreifen können, so daß in sämtlichen Borstenmaterial-Reihen 21' der Abstand zwischen aufeinanderfolgenden Borstenmaterial-Bündeln 21" auch im Bereich der Stoßstellen erhalten bleibt.4 also shows that the base bodies 22 of the insert strips 17 "can be produced as injection-molded parts made of plastic in a predetermined length, the abutting surfaces of the adjoining molded parts being able to interlock to a certain extent with trapezoidal teeth, so that all rows of bristle material 21 'The distance between successive bristle material bundles 21 "is also retained in the area of the joints.
