Description

Die Erfindung bezieht sich auf einen Markierungsnagel für Fahrbahnen, aufweisend einen Nadelkopf und einen von diesem nach unten vorstehenden in die Fahrbahn einbringba­ ren Nagelschaft.The invention relates to a marking nail for roadways, having a needle head and one of This can be inserted into the roadway above ren nail shaft.

Markierungsnägel werden in Fahrbahnen eingesetzt, um die Aufmerksamkeit des Kraftfahrers auf besondere Ge­ fahrenquellen zu lenken. Hierbei geht es nicht nur darum, daß der Kraftfahrer beim Überfahren der Markierungsnägel zu spüren bekommt, daß er eine bestimmte Linie überschrit­ ten hat, sondern es geht auch darum, daß der Kraftfahrer die Markierungsnägel bereits in größerem Abstand wahrnimmt. Dies ist jedoch nur dann sichergestellt, wenn einerseits der Kopf des Markierungsnagels auf ihn fallendes Licht in ausreichendem Maße reflektiert. Dies ist ins­ besondere bei nicht ausreichendem Tageslicht kritisch. Es kommt noch hinzu, daß insbesondere in der Winterzeit Fahrbahnen stark verschmutzt sind, so daß die an dem Nagel­ kopf vorhandenen reflektierenden Flächen nur unzureichend Licht zurückwerfen.Marking nails are used in roadways, for the driver's attention to special ge to drive sources. This is not just about that the driver when driving over the marking nails feels that it crosses a certain line ten, but it is also about the driver perceives the marking nails at a greater distance. However, this is only ensured if, on the one hand the head of the marker nail falling on it Sufficiently reflected light. This is ins especially critical when there is insufficient daylight. There is also the fact that especially in winter Roadways are very dirty, so that on the nail  insufficient existing reflective surfaces Throw back light.

Die Erfindung beschäftigt sich mit dem Problem, einen Markierungsnagel so auszugestalten, daß er in ganz besonders starkem Maße optisch sichtbar ist, ohne daß hierzu eine ka­ belgespeiste elektrische Installation erforderlich ist.The invention deals with the problem of a Marking nail so that it is very special is to a large extent optically visible, without this a ka electrical installation powered by a power supply is required.

Erreicht wird dies durch die in den Schutzansprüchen angegebenen Merkmale.This is achieved through the protection claims specified characteristics.

Für die Installation des Markierungsnagels gemäß der Erfindung ist es lediglich erforderlich, ein Loch in die Fahrbahndecke zu bohren. Hierbei können die bereits im Einsatz befindlichen Kernbohrgeräte eingesetzt werden. Nachdem der Markierungsnagel gemäß der Erfindung einge­ setzt worden ist, sind keine weiteren Installationen od. dgl. erforderlich.For the installation of the marking nail according to the Invention it is only necessary to make a hole in the Drill road surface. Here you can already in Core drills are used. After the marker nail is turned on according to the invention no further installations or Like. required.

Die Größe des Nagelkopfes kann so dimensioniert wer­ den, daß in der Zeit, in der Sonnenlicht zur Verfügung steht, die Batterien ausreichend geladen werden können, so daß diese während der Dunkelphase die Leuchtdioden ausreichend mit elektrischer Energie versorgen.The size of the nail head can be dimensioned who that in the time in the sunlight available the batteries can be charged sufficiently, so that these light emitting diodes during the dark phase provide sufficient electrical energy.

Eine Blinklichtschaltung sorgt dafür, daß die Licht­ dioden nur intervallweise Strom erhalten. Nach einer ab­ gewandelten Ausführungsform könnte ein Temperaturfühler auf diese Blinklichtschaltung Einfluß nehmen. Er kann bei sogenannten Glatteistemperaturen die Blinklichtschal­ tung auf eine höhere Frequenz umschalten, so daß durch diese relativ hohe Frequenz dem Autofahrer die Information vermittelt wird, daß er mit Glatteis rechnen muß.A flashing light circuit ensures that the light Diodes only receive current at intervals. After an off converted embodiment could be a temperature sensor influence this flashing light circuit. He can the flashing light scarf at so-called black ice temperatures device switch to a higher frequency so that by this relatively high frequency gives the driver the information is conveyed that he must expect black ice.

Die Erfindung wird nachstehend an Hand der Figur beispielsweise erläutert.The invention is described below with reference to the figure for example explained.

Diese zeigt eine schaubildliche Ansicht eines Mar­ kierungsnagels gemäß der Erfindung.This shows a graphical view of a Mar Kierungsnagels according to the invention.

Mit 10 ist ein Nagelkopf bezeichnet, an dessen un­ terem Ende sich ein zylindrischer Nagelschaft 11 befindet. Anstelle des zylindrischen kann auch ein profilierter Schaft verwendet werden, außerdem könnten auch zwei Nagel­ schäfte vorgesehen sein.With 10 a nail head is designated, at its un terem end there is a cylindrical nail shaft 11 . Instead of the cylindrical one, a profiled shaft can also be used, and two nail shafts could also be provided.

Der Nagelkopf hat im wesentlichen eine flache Form mit einer nur wenig oberhalb der Fahrbahnfläche liegenden Oberfläche und mit einer oder im gezeigten Beispiel vier Seitenflächen 12, 13, welche einen allmählichen Übergang von der Fahrbahnoberfläche zur Oberfläche des Nagelkopfes 10 schaffen. Derartige Ausgestaltungen von Nagelköpfen sind in einer Vielzahl bekannt, sie können im Zusammenhang mit der vorliegenden Erfindung eingesetzt werden.The nail head has essentially a flat shape with a surface just a little above the road surface and with one or, in the example shown, four side surfaces 12 , 13 , which create a gradual transition from the road surface to the surface of the nail head 10 . A large number of such designs of nail heads are known and can be used in connection with the present invention.

Gemäß der Erfindung ist jedoch der Nagelkopf 10 mit einer Ausnehmung versehen, welche in das Innere des Nagel­ kopfes hineinführt. In dieser Ausnehmung sind Solarzellen 18 untergebracht, die mit ihrer Wirkfläche nach oben weisen. Ebenfalls in dieser Ausnehmung und mit der Betätigungsfläche nach oben ist in der Ausnehmung ein Sensorschalter 19 un­ tergebracht. Die Solarzelle 18 und der Sensorschalter 19 können durch eine Kunststoffplatte nach oben abgedeckt sein, so daß die empfindlichen Teile 18 und 19 gegenüber Belastung durch Fahrzeuge geschützt sind. Der Kunststoffteil muß aller­ dings das auf ihn fallende Sonnenlicht durchlassen, damit die Teile 18 und 19 ihre noch zu erläuternde Funktion aus­ führen können.According to the invention, however, the nail head 10 is provided with a recess which leads into the interior of the nail head. In this recess, solar cells 18 are accommodated, which face upwards with their active surface. Also in this recess and with the actuating surface up, a sensor switch 19 is accommodated in the recess. The solar cell 18 and the sensor switch 19 can be covered by a plastic plate upwards, so that the sensitive parts 18 and 19 are protected against vehicle loads. The plastic part must, however, let the sunlight fall on it, so that the parts 18 and 19 can perform their function to be explained.

Am Nagelkopf 10 ist die vordere seitliche Fläche 12 mit einer Ausnehmung 16 versehen. Die Übergänge zur Ober­ fläche und den seitlichen Flächen sind abgerundet ausgestal­ tet. In einer in einem Winkel nahe bei 90° zur Fahrbahn angeordneten Fläche dieser Ausnehmung 16 befinden sich drei Leuchtdioden 17. Diese befinden sich mithin wenige Millimeter oberhalb der Fahrbahnoberfläche und bei zweck­ mäßigem Einbau des Markierungsnagels kann ihr Licht von Kraftfahrern von sich nähernden Fahrzeugen gesehen werden.The front lateral surface 12 is provided with a recess 16 on the nail head 10 . The transitions to the surface and the side surfaces are rounded. Three light-emitting diodes 17 are located in an area of this recess 16 arranged at an angle close to 90 ° to the roadway. These are therefore a few millimeters above the road surface and if the marker nail is installed appropriately, their light can be seen by motorists from approaching vehicles.

Die Solarzellen 18 sind mit nicht gezeigten Batterien verbunden, die sich in den Teilen 10 oder 11 befinden können. Bei auffallendem Tageslicht werden die Batterien geladen. The solar cells 18 are connected to batteries, not shown, which can be located in parts 10 or 11 . The batteries are charged in the daylight.

Tritt Dunkelheit in ausreichendem Maße ein, so spricht der Sensorschalter 19 an und stellt eine elektrische Verbindung zu den Batterien und den Leuchtdioden 17 direkt her oder über eine nicht gezeigte Blinklichtschaltung, die ebenfalls im Nagelkopf 10 oder in dem Nagelschaft 11 untergebracht ist. Die Folge ist, daß, solange Dunkelheit herrscht, die Leuchtdioden 17 Blinklichtsignale abgeben.If there is sufficient darkness, the sensor switch 19 responds and establishes an electrical connection to the batteries and the light-emitting diodes 17 directly or via a flashing light circuit, not shown, which is likewise accommodated in the nail head 10 or in the nail shaft 11 . The result is that as long as there is darkness, the light emitting diodes emit 17 flashing light signals.
