Description

Die Erfindung bezieht sich auf eine Kontaktmatte gemäß dem Gattungsbegriff des Anspruches 1.The invention relates to a contact mat according to the preamble of claim 1.

Solche Kontaktmatten sind an sich bekannt. Sie dienen den verschiedensten Einsatzzwecken. So werden sie beispielsweise als Trittstufenkontakte bei Omnibussen oder als Trittkontakte bei Gebäudetüren eingesetzt. Eine Kontaktmatte, von der die vorliegende Erfindung insbesondere ausgeht, ist in der DE-GMS 19 71 111 offenbart. Bei solchen Kontaktmatten wird beim Betreten der Matte eine Druckwelle in dem im Schlauch eingeschlossenen Fluid, insbesondere Druckluft, erzeugt und über die Länge des Schlauches zu einem angeschlossenen Druckwellenschalter geleitet. Dieser Druckwellenschalter setzt die Druckwelle in einen elektrischen Impuls um, der beispielsweise die zu betätigende Tür automatisch öffnet.Such contact mats are known per se. They serve a wide variety of purposes. For example, they are used as step contacts on buses or as step contacts on building doors. A contact mat, from which the present invention is based in particular, is disclosed in DE-GMS 19 71 111. In the case of such contact mats, a pressure wave is generated in the fluid enclosed in the hose, in particular compressed air, when the mat is entered and is passed over the length of the hose to a connected pressure wave switch. This pressure wave switch converts the pressure wave into an electrical impulse that, for example, automatically opens the door to be operated.

Ander bekannte Kontaktmatten (US-PSen 3,784,768 und 3,916,214) arbeiten mit Plattenpaaren aus elektrisch leitendem Material, die im unbelasteten Zustand mittels Distanzstücken parallel zueinander gehalten sind, um einen offenen Schalter eines elektrischen Schaltkreises zu bilden, während sie im belasteten Zustand zwischen den Distanzstücken einander genähert werden und einander berühren, um den Schalter des Schaltkreises im geschlossenen Zustand zu bilden. Das Ein- und Ausschalten des so von den Plattenpaaren gebildeten elektrischen Berührungsschalters bewirkt mittels des Schaltkreises ein registrierbares Signal, das beispielsweise das Verlassen des Startes durch einen Wettkämpfer bei sportlichen Veranstaltungen (Entlasten der Kontaktmatte) oder das Erreichen des Zieles durch den Wettkämpfer (Belasten der Kontaktmatte) anzeigen kann.Other known contact mats (US Pat. Nos. 3,784,768 and 3,916,214) work with pairs of plates made of electrically conductive material, which are kept parallel to one another in the unloaded state by means of spacers to form an open switch of an electrical circuit, while in the loaded state they approach each other between the spacers and touch each other to form the switch of the circuit when closed. Switching the electrical contact switch formed by the plate pairs on and off in this way causes a registerable signal by means of the circuit, for example a competitor leaving the start at sporting events (relieving the contact mat) or reaching the goal by the competitor (loading the contact mat) ) can display.

Auf ähnliche Weise arbeitet auch eine bekannte Einbruchsicherung (US-PS 4,311,889), bei der ein Draht aus elektrisch leitendem Material zwischen zwei Fixpunkten gespannt ist und in der Mitte so einem elektrischen Schaltkreis zugeordnet ist, daß er im unbelasteten Zustand eines darüberliegenden Fußbodens einen Schalter des Schaltkreises in dessen Öffnungsstellung unbeeinflußt läßt, im belasteten Zustand des Fußbodens jedoch in seinem mittleren Bereich durchgebogen wird und dadurch den Schalter in seine Schließstellung bringt, wodurch mittels des Schaltkreises ein Signal erzeugt wird, das die Belastung des Fußbodens anzeigt. Es kann so das Begehen des Fußbodens durch einen unbefugten Eindringling angezeigt werden.A known burglar alarm (US Pat. No. 4,311,889) works in a similar manner, in which a wire made of electrically conductive material is stretched between two fixed points and in the middle is assigned to an electrical circuit in such a way that it switches a switch in the unloaded state of an overlying floor Circuit in its open position unaffected, but is deflected in the loaded state of the floor in its central area and thereby the switch in his Brings closed position, whereby a signal is generated by the circuit that indicates the load on the floor. An unauthorized intruder can be used to indicate that the floor has been walked on.

Bei den bekannten gattungsgemäßen Druckmatten wird der Druckwellenschlauch von einem Ende der Matte aus wellen- oder mäanderförmig durch diese hindurch zum anderen Ende geführt, um dort aus der Matte herausgeführt und an den Druckwellenschalter angeschlossen zu werden. Um den Schlauch nicht zu stark im Hinblick auf seine Verformbarkeit abbiegen zu müssen, müssen realtiv große Biegeradien gewählt werden und ein relativ dünner Druckschlauch Anwendung finden. Dies führt dazu, daß ein relativ großer Anteil der Fläche der Kontakmatte außerhalb des Druckwellenschlauchbereiches zu liegen kommt und ein Ansprechen der Matte nicht an allen Stellen gewährleistet ist. Der relativ geringe Querschnitt des Druckwellenschlauches führt außerdem dazu, daß die Empfindlichkeit der Matte nicht sehr groß und ein hoher Kraftaufwand notwendig ist, um den Preßluftstrom am Druckwellenschalter zur Wirkung zu bringen.In the known generic pressure mats, the pressure wave hose is guided from one end of the mat in a wave or meandering manner through it to the other end in order to be led out of the mat and connected to the pressure wave switch. In order not to have to bend the hose too much with regard to its deformability, relatively large bending radii must be selected and a relatively thin pressure hose must be used. This means that a relatively large proportion of the surface of the contact mat comes to lie outside the pressure wave hose area and that the mat does not respond at all points. The relatively small cross-section of the pressure wave hose also means that the sensitivity of the mat is not very high and a high level of force is required to bring the compressed air flow to the pressure wave switch.

Diese Verhältnisse reichen im allgemeinen aus, wenn die Kontaktmatten bei Trittstufenkontakten bei Fahrzeugen oder in Verbindung mit Gebäudetüren angewendet werden. Es gibt jedoch Anwendungsfälle, in denen ein besseres Ansprechen der Kontakmatten sowie zwei Ausgänge verlangt wird bzw. werden. Ein solcher Anwendungsfall ist beispielsweise die Arbeitsplatzsicherung für Arbeitsmaschinen wie sie von den Gewerbeaufsichtsämtern und Berufsgenossenschaften verlangt wird.These conditions are generally sufficient if the contact mats are used for tread contacts in vehicles or in connection with building doors. However, there are applications in which a better response of the contact mats and two outputs are required. One such application is, for example, job security for work machines, as required by trade inspectorates and professional associations.

Aufgabe der Erfindung ist die Weiterentwicklung der gattungsgemäßen Kontaktmatte in der Weise, daß eine erheblich größere Empfindlichkeit mit relativ geringem baulichen Aufwand erreicht wird.The object of the invention is the further development of the generic contact mat in such a way that a considerably greater sensitivity is achieved with relatively little structural effort.

Der Lösung der Aufgabe dienen die Merkmale der Patentansprüche.The features of the claims serve to solve the problem.

Nachfolgend ist die Erfindung anhand der Zeichnung näher erläutert. In der Zeichnung zeigen

  • Fig.1 eine Draufsicht auf die erfindungsgemäße Kontaktmatte,
  • Fig.2 einen Schnitt nach der Linie A-B in Fig.l und
  • Fig.3 eine bauliche Einzelheit der Anordnung gemäß Fig.1
The invention is explained in more detail below with reference to the drawing. Show in the drawing
  • 1 is a plan view of the contact mat according to the invention,
  • 2 shows a section along the line AB in Fig.l and
  • 3 shows a structural detail of the arrangement according to FIG

Die eigentliche Kontaktmatte 1 besteht aus einer Grundplatte aus mit Hypalon beschichtetem Treviragewebe dreifach, einer Zwischenmatte aus Zellkautschuk, sowie einer Abdeckplatte, die ebenfalls aus einem mit Hypalon beschichtetem Treviragewebe besteht. Für die Grundplatte und die Abdeckplatte sind jedoch auch andere Materialien möglich, beispielsweise Gummiplatten, Gummiriefenplatten oder Aluminiumnoppenblech. Wichtig ist, daß die Kontaktmatte gut auf ihrer Unterlage haftet und der auf ihr stehenden Person ausreichende Rutschsicherheit gewährleistet. Am Außenumfang ist die Kontaktmatte mit einem Tesaband oder dergleichen eingefaßt. Die Kontaktmatte ist im Beispiel eine rechteckige, vorzugsweise quadratische Platte. In dieser Platte sind zwei konzentrisch zueinander und spiralförmig angeordnete Druckwellenschlauchabschnitte 2,3 eingelegt. Sie sind mit ihren einen Enden in der Mitte der Kontaktmatte zusammengeführt, während ihre beiden anderen Enden im Bereich einer Mattenseite nahe einer Mattenecke aus der Kontaktmatte herausgeführt sind und so eine Kontaktmatte mit zwei Ausgängen gegeben ist. Der Durchmesser des Druckwellenschlauches 2,3 ist größer als die Dicke der Kontakmatte 1. Der Druckwellenschlauch liegt so in zwei Rinnen 4,5 der Kontakmatte, daß deren Oberseite 6 glatt oder vorzugsweise leicht gewellt und eben ist, während ihre Unterseite 7 Rippen von der Höhe aufweist, um die der Durchmesser des Druckwellenschlauches größer als die Dicke der Kontaktmatte ist.The actual contact mat 1 consists of a base plate made of triple coated with Hypalon Trevira fabric, an intermediate mat made of cellular rubber, and a cover plate, which also consists of a Trevira fabric coated with Hypalon. However, other materials are also possible for the base plate and the cover plate, for example rubber plates, rubber grooved plates or aluminum knobbed sheet. It is important that the contact mat adheres well to its surface and guarantees sufficient slip resistance for the person standing on it. The contact mat is bordered on the outer circumference with a tape or the like. In the example, the contact mat is a rectangular, preferably square, plate. Two pressure wave hose sections 2, 3, which are arranged concentrically to one another and spirally, are inserted into this plate. They are brought together with their one ends in the middle of the contact mat, while their other two ends are led out of the contact mat in the area of a mat side near a mat corner, thus giving a contact mat with two exits. The diameter of the pressure wave hose 2, 3 is greater than the thickness of the contact mat 1. The pressure wave hose lies in two grooves 4, 5 of the contact mat in such a way that the top 6 thereof is smooth or preferably slightly undulated and flat, while its underside 7 ribs of height has by which the diameter of the pressure wave hose is greater than the thickness of the contact mat.

Die Verbindung der Druckwellenschlauchabschnitte in der Kontaktmattenmitte erfolgt mit einem einen Schlauchbogen bildenden Formteil 8, auf dessen Enden die inneren Enden der Druckwellenschlauchabschnitte aufgeschoben und haltbar verklebt sind. Um den relativ engen Krümmungen im Bereich der Kontaktmattenmitte Rechnung zu tragen, wird auch noch der an den Schlauchbogen des Formteiles 8, anschließende Bogen von einemn entsprechenden Formteil 9 gebildet. Beide Formteile 8,9 sind seitlich um den Bogendurchmesser gegeneinander versetzt, so daß der "innere" Schenkel des einen Formteiles 8 gleichachsig zum "äußeren" Schenkel des anderen Formteiles 9 zu liegen kommt und diese beiden Schenkel unmittelbar oder über ein kurzes Schlauchstück miteinander verbunden sind. Die Anschlußstutzen der Formteile, auf die der Druckwellenschlauch 2,3 aufgeschoben wird, sind mit äußeren Riefen 10 versehen, so daß Formteile und Druckwellenschlauch zuverlässig miteinander verklebt werden können.The connection of the pressure wave hose sections in the center of the contact mat takes place with a molded part 8 forming a hose bend, on the ends of which the inner ends of the pressure wave hose sections are pushed on and glued in a durable manner. In order to take account of the relatively narrow curvatures in the area of the center of the contact mat, the bend adjoining the tubular bend of the molded part 8 is also formed by a corresponding molded part 9. Both molded parts 8, 9 are laterally offset from one another by the arc diameter, so that the "inner" leg of one molded part 8 comes to lie coaxially with the "outer" leg of the other molded part 9 and these two legs are connected to one another directly or via a short piece of hose . The connecting pieces of the molded parts, onto which the pressure wave hose 2, 3 is pushed, are provided with external grooves 10, so that the molded parts and pressure wave hose can be reliably glued together.

Über den doppelten Ausgang der Kontaktmatte ist diese an eine im Handel erhältliche, sich selbst überwachende DWPS-Kombination anschließbar, die ein pneumatisches Sicherheitssystem ist, das aus der eigentlichen Uberwachungskombination und einem über Schlauchleitung (den Druckwellenschlauch 2,3) verbundenem Druckgeber besteht. Die DWPS-Kombination beinhaltet unter anderem vier spezielle Druckwellenschalter, wovon zwei die Steuerung des Geberdruckes und zwei der Pumpensteuerung dienen.Via the double output of the contact mat, it can be connected to a commercially available, self-monitoring DWPS combination, which is a pneumatic safety system that consists of the actual monitoring combination and a pressure sensor connected via a hose line (the pressure wave hose 2, 3). The DWPS combination includes four special pressure wave switches, two of which are used to control the transmitter pressure and two to control the pump.
