Description

Die Erfindung betrifft einen bahnförmigen textilen Bodenbelag mit oder ohne Trägerschicht jeglicher Art, mit einer für elektrostatische Ladungen ableitfähigen Nutzschicht und netzförmig angeordneten, geerdeten elektrischen Leitern, sowie ein Verfahren zu seiner Verlegung.The invention relates to a web-shaped textile floor covering with or without a backing layer of any kind, with a wear layer that can be dissipated for electrostatic charges, and earthed electrical conductors arranged in a network, and a method for its laying.

Textile Bodenbeläge, wie Teppichböden, Filze oder Vliese z. B. mit einer vorgefertigten oder bei der Herstellung der Nutzschicht erzeugten Trägerschicht, können sich, insbesondere, wenn sie aus synthetischem Material bestehen, bei geringer relativer Luftfeuchtigkeit durch Reibung aufladen. Diese Aufladung, die Potentiale von bis zu 10 000 Volt erreichen kann, hat zwar keinen unmittelbar schädigenden Einfluß, sie wirkt sich aber auf den Menschen unangenehm aus, weil beim Berühren von Metallteilen Funkenüberschläge erfolgen. Außerdem können hochempfindliche elektronische Anlagen, wie Computer, sowohl durch die Aufladung als auch durch den Funkenüberschlag gestört werden.Textile floor coverings, such as carpets, felts or nonwovens z. B. with a prefabricated or produced in the manufacture of the wear layer carrier layer, especially if they consist of synthetic material, charge at low relative humidity by friction. This charge, which can reach potentials of up to 10,000 volts, does not have an immediate damaging effect, but it has an unpleasant effect on people because sparking occurs when metal parts are touched. In addition, highly sensitive electronic systems such as computers can be disturbed by both charging and sparking.

Im übrigen kann auf dem menschlichen Körper elektrische Ladung entstehen durch andere Ursachen als Reibung zwischen Schuhwerk und Bodenbeiag, nämlich durch Reibung von hauptsächlich synthetischer Wäsche auf dem menschlichen Körper. Diese kann jedoch nur auf den Bodenbelag gelangen, falls leitfähiges Schuhmaterial vorliegt.Incidentally, electrical charge can arise on the human body from causes other than friction between footwear and floor covering, namely from the rubbing of mainly synthetic laundry on the human body. However, this can only get onto the flooring if there is conductive shoe material.

Bei einem textilen Bodenbelag der eingangs genannten Art (US-A-3713960) ist die Nutzschicht an einer Trägerschicht befesigt, die aus Polypropylenstreifen mit rechteckigem Querschnitt besteht, welche an ihrer Unterseite jeweils eine Aluminiumfolie tragen. Die Polypropylenstreifen sind als Schuß und Kette verwebt und ihre Folienstreifen bilden ein flächenförmiges Leiternetz. Die Folien der sich kreuzenden Polypropylenstreifen haben untereinander keinen elektrischen Kontakt, da sie durch die nicht-leitenden Polypropylenstreifen voneinander getrennt sind. Der Kontakt erfolgt über die durch die Trägerschicht hindurchgezogenen Kunststoffäden der Nutzschicht punktförmig.In the case of a textile floor covering of the type mentioned at the beginning (US-A-3713960), the wear layer is attached to a support layer which consists of polypropylene strips with a rectangular cross section, each of which has an aluminum foil on its underside. The polypropylene strips are woven as a weft and chain and their foil strips form a flat conductor network. The films of the crossing polypropylene strips have no electrical contact with one another, since they are separated from one another by the non-conductive polypropylene strips. The contact is made in a punctiform manner via the plastic threads of the wear layer that are pulled through the carrier layer.

Bei einem derartigen Bodenbelag ist es schwierig, die Folien aller Polypropylenstreifen so an eine Erdungsleitung anzuschließen, daß sich über die gesamte Fläche des Bodenbelages ein gleichmäßiger Erdableitwiderstand ergibt.In such a floor covering, it is difficult to make the films of all Polypropylenstrei f s so at a ground line to be connected, that a uniform resistance to ground results over the entire surface of the floor covering.

Aufgabe der Erfindung ist es, einen bahnförmigen textilen Bodenbelag der eingangs genannten Art zu schaffen, durch dessen Konstruktion aufgrund definierter vollflächig wirkender Erdung sich ein über die gesamte Belagfläche gleichmäßiger Erdableitungswiderstand ergibt, und dessen Erdungsanschluß schnell und einfach herstellbar ist.The object of the invention is to provide a web-shaped textile floor covering of the type mentioned, the construction of which results in a ground resistance which is uniform over the entire covering surface, and the ground connection of which can be produced quickly and easily because of the defined full-surface grounding.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß das durch die untereinander in direktem Kontakt stehenden Leiter gebildete Netz in direktem flächenförmigem Kontakt mit der Nutzschicht steht und daß ein in Bahnlängsrichtung breiterer Leiterstreifen vorgesehen ist, der mit den Leitern des Leiternetzes in Kontakt ist.To achieve this object, it is provided according to the invention that the network formed by the conductors in direct contact with one another is in direct surface contact with the wear layer and that a conductor strip wider in the longitudinal direction of the web is provided which is in contact with the conductors of the conductor network.

Ein derartiger Bodenbelag wird an Erdpotential angeschlossen, indem auf dem Fußboden quer zur vorgesehenen Bahnrichtung des Bodenbelages ein geerdetes Leiterband verlegt und an den Kreuzungspunkten des Leiterbandes mit den Leiterstreifen jeweils ein "lontaktelement durch den Bodenbelag in den Fußboden getrieben wird.Such a floor covering is connected to earth potential by laying an earthed conductor strip on the floor transversely to the intended path of the floor covering and at the points of intersection of the conductor strip with the conductor strips in each case a "lontact element" is driven through the floor covering into the floor.

Durch das flächenförmige Leiternetz, das direkt Kontakt mit der Nutzschicht hat und an Erdungsanschluß angeschlossen ist, wird eine definierte Ableitfähigkeit über die gesamte Bodenfläche erreicht, d. h. es ergibt sich eine vollflächige definierte Erdung der Bodenbelagfläche. Die Herstellung der elektrischen Verbindung des Leiternetzes erfolgt über den Leiterstreifen, in dessen Bereich ein Verbindungselement durch den Bodenbelag hindurchgetrieben wird. Der Erdungsanschluß wird in Kontakt mit dem Verbindungselement gebracht. Das Kontaktelement erhält somit elektrischen Kontakt sowohl mit dem betreffenden Leiterstreifen als auch mit dem Leiterband. Bei dem Kontaktelement kann es sich um einen Nagel, eine Schraube o. dgl. handeln.Due to the flat conductor network, which has direct contact with the wear layer and is connected to the earth connection, a defined conductivity is achieved over the entire floor area, i. H. there is a full-surface defined grounding of the floor covering. The electrical connection of the conductor network is established via the conductor strip, in the area of which a connecting element is driven through the floor covering. The ground connection is brought into contact with the connecting element. The contact element thus receives electrical contact both with the conductor strip in question and with the conductor strip. The contact element can be a nail, a screw or the like.

Auf diese Weise wird der gesamte Bodenbelag an Erdpotential angeschlossen, wobei eine auf dem Bodenbelag gehende Person jedoch über einen ausreichend hohen Widerstand geerdet ist. Der Erdungsanschluß bewirkt, daß innerhalb des gesamten Bodenbelags Erdpotential herrscht, so daß das Spannungspotential an jeder Stelle des Bodenbelages stets Null beträgt. Lediglich wenn beispielsweise eine auf dem Bodenbelag stehende Person eine elektrische Stromleitung berührt und sich der hohe Widerstand der Nutzschicht schützend auswirkt, kann vorübergehend eine Spannungsdifferenz am Bodenbelag auftreten.In this way, the entire floor covering is connected to earth potential, but a person walking on the floor covering is earthed via a sufficiently high resistance. The earth connection ensures that there is earth potential within the entire floor covering, so that the voltage potential is always zero at every point on the floor covering. Only if, for example, a person standing on the floor covering touches an electrical power line and the high resistance of the wear layer has a protective effect, can a voltage difference occur temporarily on the floor covering.

Die elektrischen Leiter, die untereinander in Kontakt stehen, bilden eine gitterförmige Lage, die in direktem Kontakt mit der Nutzschicht steht, und sie haben gleichzeitig elektrische Verbindung mit dem Leiterstreifen. Auf diese Weise ist sichergestellt, daß sowohl in Längsrichtung als auch in Querrichtung des Bodenbelages eine elektrische Ableitung erfolgt. Au:, einer Bodenbelagbahn können an beliebiger Stelle Stücke herausgeschnitten werden, die sämtlich vollflächig das gitterförmige Leiternetz enthalten, so daß an allen Stellen des Bodenbelages eine Verteilung und Ableitung von Ladungsträgern möglich ist. Werden einzelne Stücke des Bodenbelages gegeneinandergesetzt, dann können die Leiter der aneinander angrenzenden Stücke miteinander verbunden werden.The electrical conductors, which are in contact with one another, form a grid-shaped layer which is in direct contact with the wear layer, and at the same time they have an electrical connection with the conductor strip. In this way it is ensured that electrical discharge takes place both in the longitudinal direction and in the transverse direction of the floor covering. Au :, pieces of a floor covering can be cut out at any point, all of which contain the grid-shaped conductor network, so that a distribution and discharge of charge carriers is possible at all points of the floor covering. If individual pieces of the floor covering are placed against one another, the conductors of the adjacent pieces can be connected to one another.

Der Widerstand zwischen zwei Punkten des Bodenbelages liegt bei dieser Ausbildung in der Größenordnung von 106 bis 108 Ohm. Der Erdableitungswiderstand ist von derselben Größenordnung. Innerhalb des Bodenbelages soll der elektrische Widerstand zum Abführen der Ladungen zwar möglichst gering sein, jedoch sollte vermieden werden, daß der Körper einer Person, die auf dem Bodenbelag steht oder geht, niederohmig geerdet wird. In diesem Falle wäre die Gefährdung beim Berühren einer Stromleitung zu groß. Der erforderliche Übergangswiderstand zwischen den geerdeten Leitern im Inneren des Bodenbelages und einem auf dem Bodenbelag befindlichen Körper wird von der Nutzschicht gebildet. Dies bedeutet, daß bei einer Widerstandsmessung auf dem Bodenbelag die Entfernung der beiden Meßpunkte, zwischen denen der Widerstand gemessen wird, das Meßergebnis nur ganz unwesentlich beeinflußt.The resistance between two points of the floor covering is in this training The order of 10 6 to 10 8 ohms. The earth leakage resistance is of the same order of magnitude. The electrical resistance for discharging the charges within the floor covering should be as low as possible, but it should be avoided that the body of a person standing or walking on the floor covering is grounded with a low resistance. In this case, the risk of touching a power line would be too great. The required contact resistance between the earthed conductors inside the floor covering and a body located on the floor covering is formed by the wear layer. This means that when measuring resistance on the floor covering, the distance between the two measuring points, between which the resistance is measured, has only a very negligible influence on the measurement result.

Die Erfindung ist bei Ve!ourteppichen anwendbar, sie kann aber auch bei allen anderen Arten von textilen Bodenbelägen mit oder ohne Trägerschicht realisiert werden, beispielsweise bei Boucleware und bei ebener Ware (Nadelfilz).The invention can be used with Ve! Our carpets, but it can also be implemented with all other types of textile floor coverings with or without a backing layer, for example with boucleware and with flat goods (needle felt).

Die elektrischen Leiter können wellenförmig verlaufen, wobei die Wellen seitlich benachbarter Leiter sich in gegenseitigem Kontakt überlappen. Die Wellen können sinusförmig, dreieckförmig, rechteckförmig usw. sein. Die weilenförmige Verlegung hat den Vorteil einer besonders einfachen Fertigung.The electrical conductors can run in the form of waves, the waves of laterally adjacent conductors overlapping in mutual contact. The waves can be sinusoidal, triangular, rectangular, etc. The hamlet-shaped installation has the advantage of particularly simple manufacture.

Alternativ können die elektrischen Leiter entweder geradlinig oder verschlungen, einander kreuzend, verlaufen.Alternatively, the electrical conductors can be either straight or intertwined, crossing one another.

Vorzugsweise sind die elektrischen Leiter in direktem Kontakt zur Nutzschicht zwischen dieser und einer beliebigen Rückenlage angeordnet oder in direktem Kontakt zur Nutzschicht in die die Nutzschicht tragende Trägerschicht unmittelbar eingearbeitet. Die Leiter sowie die Leiterstreifen haben eine ganz geringe Stärke, so daß sie in der Kontur des Bodenbelages nicht in Erscheinung treten. Die Stärke beträgt beispielsweise ca. 0,15 mm.The electrical conductors are preferably arranged in direct contact with the wear layer between the latter and any back layer or in direct contact with the wear layer in the carrier layer carrying the wear layer. The conductors and the conductor strips have a very small thickness, so that they do not appear in the contour of the floor covering. The thickness is, for example, approximately 0.15 mm.

Im folgenden wird ein bevorzugtes Ausführungsbeispiel der Erfindung unter Bezugnahme auf die Figuren näher erläutert.

  • Fig. 1 zeigt schematisch einen Querschnitt durch einen Velour-Teppichboden mit einem durch den Leiterstreifen getriebenen Verbindungselement,
  • Fig. 2 zeigt eine Draufsicht auf eine Rückenlage mit aufgelegten elektrischen Leitern und Leiterstreifen, und
  • Fig. zeigt in Draufsicht das Schema einer Verlegung mehrerer Bodenbelagbahnen in einem Raum.
A preferred embodiment of the invention is explained in more detail below with reference to the figures.
  • 1 schematically shows a cross section through a velor carpet with a connecting element driven by the conductor strip,
  • Fig. 2 shows a plan view of a supine position with electrical conductors and conductor strips, and
  • Fig. Shows a top view of the scheme of laying several flooring sheets in a room.

Der ir Fig.1 dargestellte Velour-Teppichboden weist eine Rückenlage 10 aus Filz, einem Schaumstoffmaterial o. dgl auf. Auf der Rückenlage 10 befindet sich eine Klebeschicht 11, z. B. aus Polyäthylen, die die Pulträgerschicht 20 mit der Rückenlage verbindet. 12 bezeichnet die Pulhaare der Nutzschicht, die durch die Trägerschicht 20 durchgearbeitet sind.The velor carpet shown in FIG. 1 has a back layer 10 made of felt, a foam material or the like. On the supine layer 10 there is an adhesive layer 11, for. B. from polyethylene, which connects the desk support layer 20 with the supine. 12 denotes the pulse hairs of the wear layer, which are worked through through the carrier layer 20.

Auf die Klebeschicht 11 sind auf der der Trägerschicht 20 zugewandten Seite draht- oder bandförmige elektrische Leiter 13 aufgelegt, die gemäß Fig. 2 in Längsrichtung der Teppichbahn 14 verlaufen und wellenförmig verlegt sind. Die Wellen der einzelnen Leiter 13 überlappen sich teilweise, so daß seitlich benachbarte Leiter 13 in direktem Kontakt miteinander und mit den Polhaaren 12 stehen. Die Überlappungen erfolgen jeweils an den Maxima der Wellenlinien. Auf diese Weise ist die gesamte Fläche der Trägerschicht 20 bzw. der Klebeschicht 11 mit Leitern belegt, die sich in Längsrichtung der Bahn 14 erstrecken und untereinander Querverbindungen haben.Wire or tape-shaped electrical conductors 13 are placed on the adhesive layer 11 on the side facing the carrier layer 20, which conductors run in the longitudinal direction of the carpet web 14 according to FIG. 2 and are laid in a wave shape. The waves of the individual conductors 13 partially overlap, so that laterally adjacent conductors 13 are in direct contact with one another and with the pole hairs 12. The overlaps occur at the maxima of the wavy lines. In this way, the entire surface of the carrier layer 20 or the adhesive layer 11 is covered with conductors which extend in the longitudinal direction of the web 14 and have cross connections to one another.

In Längsrichtung der Bahn 14 verläuft ferner in der Nähe der einen Bahnkante ein Leiterstreifen 15. Dieser kann z. B. aus einer sehr dünnen Metallfolie bestehen und steht in elektrischem Kontakt mitden Leitern 13. Er dient zur Ermöglichung eines elektrischen Anschlusses an eine externe Erdungseinrichtung.In the longitudinal direction of the web 14, a conductor strip 15 also runs near one of the web edges. B. consist of a very thin metal foil and is in electrical contact with the conductors 13. It serves to enable an electrical connection to an external grounding device.

An dem Leiterstreifen 15 ist zur Herstellung der Erdungsverbindung ein Nagel 16 oder ein anderes leitendes Verbindungsteil durch den Bodenbelag hindurchgetrieben, so daß es in leitender Verbindung mit dem Leiterstreifen 15 steht. Unterhalb des Bodenbelages ist auf dem Fußboden 17 ein Leiterband 18 verlegt, das quer zu den Leiterstreifen 15 sämtlicher Bodenbelagbahnen verläuft, wie aus Fig. 3 hervorgeht. Das Leiterband 18 ist mit einem Erdungsanschluß 19 verbunden und leitet das Erdpotential an die verschiedenen Leiterelemente 16, die es auf die Leiterstreifen 15 der nebeneinanderliegenden Bodenbelagbahnen weiterleiten. Die einzige Installation, die auf dem Fußboden vorgenommen werden muß, besteht in der Befestigung des Leiterbandes 18, das zweckmäßigerweise aufgeklebt wird.On the conductor strip 15, a nail 16 or another conductive connecting part is driven through the floor covering to produce the ground connection, so that it is in conductive connection with the conductor strip 15. A conductor strip 18 is laid below the floor covering on the floor 17 and runs across the conductor strips 15 of all the floor covering tracks, as can be seen from FIG. 3. The conductor strip 18 is connected to an earth connection 19 and conducts the earth potential to the various conductor elements 16, which pass it on to the conductor strips 15 of the adjacent floor covering tracks. The only installation that has to be carried out on the floor is to fasten the conductor strip 18, which is expediently glued on.
