Abstract

A safety covering for guide or guard rails has a plastic element of bright material. Besides a contour corresponding to the guide rail front side to be covered, tabs for engaging the guide rail edges from behind are provided at the longitudinal edges. A special reflecting insert can augment the optical effect. Signal surfaces applied additionally on the safety coverings at an angle of less than 90 DEG can impart further optical information to drivers. By local application of such safety coverings on guide rails, optical traffic guidance can be enhanced and easily modified.

Description

Die Erfindung betrifft einen Sicherheitsüberzug für Leitplanken.The invention relates to a safety cover for guardrails.

Leitplanken dienen zur örtlichen und optischen Begrenzung der Fahrbahn von Motorfahrzeugen. Sicherheitsüberzüge für Leitplanken verbessern die optische Wahrnehmung der Breite und Richtung der Fahrbahn und sind somit ein Instrument der optischen Verkehrsführung.Guardrails serve to locally and visually limit the roadway of motor vehicles. Safety covers for guardrails improve the visual perception of the width and direction of the road and are therefore an instrument of optical traffic management.

Aus den Dokumenten FR-A-2 416 303 und FR-A-451 606 sind Sicherheitsüberzüge für Leitplanken als schmutzabweisende, lichtreflektierende Fahrbahnsignalisationen bekannt, die Mittel zum Festmachen an die Leitplanke aufweisen und auf ihre Fahrbahn zugekehrte Seite eine aus dem Sicherheitsüberzug hervorragende, gegenüber dem Gesamtaspekt andersartige, vorzugsweise farbig reflektierende, Signalfläche besitzen. Bekannt ist ferner, dass die Signalfläche mit reflektierenden graphischen Zeichen belegt werden kann.From the documents FR-A-2 416 303 and FR-A-451 606, safety covers for guardrails are known as dirt-repellent, light-reflecting roadway signaling devices, which have means for attaching to the guardrail and have an outstanding side of the safety cover on their side facing the roadway Overall aspect have different, preferably color reflecting, signal area. It is also known that the signal surface can be covered with reflective graphic characters.

Die vorliegende Erfindung liegt der Aufgabe zugrunde, die optische Verkehrsführungsfunktion der Leitplanken zu verbessern, bzw. zu ergänzen.The present invention is based on the object of improving or supplementing the optical traffic management function of the crash barriers.

Durch geeignete Gestaltung und Anordnung der Sicherheitsüberzugselemente ist eine erweiterte Einflussnahme auf den Verkehr möglich, indem die Lage der reflektierenden Signalflächen optimiert, und vor und in den Kurven dem Fahrzeuglenker den Eindruck einer Fahrzeugbeschleunigung vermittelt wird. Ferner wird angestrebt durch geeignete Belegung der Sicherheitsüberzugselemente mit reflektirenden graphischen Zeichen den Fahrzeuglenker vor irrtümlicher Benützung der Fahrbahn im Gegenverkehr zu warnen, und somit ihn nicht nur über die Richtung der Fahrbahn sondern über die geltende Fahrtrichtung zu informieren.With a suitable design and arrangement of the safety cover elements, it is possible to exert an increased influence on traffic by optimizing the position of the reflecting signal areas and giving the vehicle driver the impression of vehicle acceleration in front of and in the bends. Furthermore, by appropriately covering the safety cover elements with reflective graphic signs, the aim is to warn the driver of the vehicle against mistaken use of the lane in oncoming traffic, and thus to inform him not only about the direction of the lane but about the applicable direction of travel.

Die Lösung dieser Aufgaben wird durch die kennzeichnenden Merkmale der Ansprüche 1 bis 3 gelöst.The solution to these problems is solved by the characterizing features of claims 1 to 3.

Die Erfindung bietet demnach die Möglichkeit, eine Einflussnahme auf die Geschwindigkeit des örtlichen Verkehrs, beispielsweise vor Kurven, Kreuzungen und anderen Gefahrenstellen, durch stellenweises Anbringen von Sicherheitsüberzugselementen auf die Leitplanken, und durch immer kürzere Abstände der aufeinander folgenden Sicherheitsüberzugselemente, die den Fahrzeuglenker den Eindruck steigender Fahrzeugbeschleunigung vermitteln.The invention accordingly offers the possibility of influencing the speed of local traffic, for example in front of bends, intersections and other danger points, by attaching safety covering elements to the guardrails in places, and by increasing and shorter distances between the successive safety covering elements, which give the driver the impression of increasing impression Convey vehicle acceleration.

Ausserdem können die selben Sicherheitsüberzugselemente auch andere Signale tragen, z.B. zur Warnung potentieller Geisterfahrer, die irrtümlicherweise auf Autobahnen geraten sind und ihr Fahrzeug entgegen der zulässigen Fahrtrichtung streuern.In addition, the same security cover elements can also carry other signals, for example to warn potential ghost drivers who have accidentally got onto motorways and are scattering their vehicle against the permissible direction of travel.

Der erfindungsgemässe Sicherheitsüberzug kann in Elementen von handlicher Länge hergestellt werden. Günstigerweise verwendet man einen witterungsbeständigen, preiswerten Kunststoff, wie geeignete Thermoplaste, der vorteilhaft hell, besonders weiss eingefärbt sein kann.The safety cover according to the invention can be manufactured in elements of a handy length. It is expedient to use a weather-resistant, inexpensive plastic, such as suitable thermoplastics, which can advantageously be colored bright, especially white.

Ausser der durch helle oder weisse Farbe bedingten guten Lichtreflektierung kann in besonderen Zonen des Sicherheitsüberzugselementes, z.B. als Signalfläche, eine intensive Reflektierung von Licht erfolgen, wobei dies die Unterscheidung der Leitplanke von ihrem optischen Hintergrund erheblich fördern kann. Eine solche Zone kann im Kunststoff eingelassen sein, was die Haltbarkeit fördert. Diese Intensivierung der Lichtreflektion kann durch bekannte Mittel wie Glaskugeln, Trippelspiegel etc. erreicht werden.In addition to the good light reflection caused by light or white color, special zones of the safety covering element, e.g. as a signal surface, there is an intensive reflection of light, which can significantly promote the distinction of the guardrail from its optical background. Such a zone can be embedded in the plastic, which promotes durability. This intensification of light reflection can be achieved by known means such as glass balls, triple mirrors, etc.

Eine bevorzugte Ausführungsform des Sicherheitsüberzugselementes eignet sich besonders gut für die gebräuchlichste Leitplankenform aus Stahl, mit zwei übereinander angeordneten, fahrbahnseitigen Vorwölbungen, weil sie als auf die Leitplanke aufschnappbare Kunststoffkörper wirtschaftlich realisierbar und montierbar ist. Im folgenden wird die Erfindung näher erläutert anhand einer lediglich einen Ausführungsweg darstellenden Zeichnung.A preferred embodiment of the safety cover element is particularly well suited for the most common guardrail shape made of steel, with two protrusions arranged one above the other on the roadway side, because they act on the Guardrail snap-on plastic body is economically feasible and mountable. The invention is explained in more detail below with reference to a drawing which represents only one embodiment.

Dabei sei stets zu beachten, dass der eigentliche Gegenstand der Erfindung, nicht die Sicherheitsüberzugselemente selbst sondern deren Anordnung mit der Abstandänderung der aufeinander folgenden Sicherheitsüberzugselemente entlang der Fahrbahn ist.
Es zeigt:

Figur 1.
ein Sicherheitsüberzugselement aus der zulässigen Fahrtrichtung,
Figur 2.
das selbe Sicherheitsüberzugselement aus der unzulässigen Fahrtrichtung,
Figur 3.
die Anordnung der Sicherheitselemente der linksseitigen Leitplanke einer Autobahnausfahrt aus der Perspektive des Fahrzeuglenkers,
Figur 4.
die Anordnung der Sicherheitselemente der rechtsseitigen Leitplanke einer Autobahnausfahrt aus der Perspektive eines Geisterfahrers.
It should always be noted that the actual object of the invention is not the safety covering elements themselves but rather their arrangement with the change in distance of the successive safety covering elements along the road.
It shows:
Figure 1.
a safety cover element from the permissible direction of travel,
Figure 2.
the same safety cover element from the impermissible direction of travel,
Figure 3.
the arrangement of the safety elements of the left-hand guardrail of a motorway exit from the driver's perspective,
Figure 4.
the arrangement of the security elements of the right-hand guardrail of a motorway exit from the perspective of a ghost driver.

Das im Figur 1 gezeigte Sicherheitsüberzugselement 1 entspricht der Form der häufigsten Leitplankenprofile, wobei zwei nach vorne stehende Wülste 2 von einer Nut 3 getrennt sind. Längs bei den Längsrändern 4 sind nach hinten abgebogene Halteteile 5 vorgesehen, die die Leitplankenränder hintergreifen können, so dass das Sicherheitsüberzugselement 1 unter elastischer Verformung von vorne auf eine Leitplanke 11 aufgeschnappt werden kann. In der Mitte der Nut 3 befindet sich ein Signalträger mit einer gegenüber der Fahrtrichtung mehr als 0° und weniger als 90° geneigten und besonders reflektierende Zone 6 der Signalfläche 10, die auf dem Signalträger aufliegt oder im Signalträger eingebettet ist. Im Figur 2 wird die Rückseite desselben Sicherheitsüberzugselementes 1 vom Figur 1 gezeigt, wobei die Signalfläche 10 mit Einbahnzeichen belegt ist.
Die Figuren 3 und 4 illustrieren die Anordnung der in den Figuren 1 und 2 gezeigten Sicherheitselemente 1. Da die Anordnung der Leitplanken 11, und der Sicherheitsüberzugselemente 1 auf die Leitplanken 11, beidseitig der Fahrbahn analog zu erfolgen hat, wird aus Platzgründen jeweils nur die eine Strassenseite mit der von Sicherheitsüberzugselementen 1 belegten Leitplanke 11 dargestellt.The safety covering element 1 shown in FIG. 1 corresponds to the shape of the most common guardrail profiles, two protruding beads 2 being separated by a groove 3. Longitudinally bent rearward holding parts 5 are provided at the longitudinal edges 4, which can reach behind the guardrail edges, so that the safety covering element 1 can be snapped onto a guardrail 11 from the front with elastic deformation. In the center of the groove 3 there is a signal carrier with a particularly reflective zone 6 of the signal surface 10 which is inclined to the direction of travel by more than 0 ° and less than 90 ° and which rests on the signal carrier or is embedded in the signal carrier. FIG. 2 shows the back of the same security covering element 1 from FIG. 1, the signal area 10 being covered with one-way signs.
FIGS. 3 and 4 illustrate the arrangement of the safety elements 1 shown in FIGS. 1 and 2. Since the arrangement of the crash barriers 11 and the safety covering elements 1 on the crash barriers 11 has to be carried out analogously on both sides of the carriageway, only one is used for reasons of space Street side shown with the guardrail 11 occupied by safety cover elements 1.

In der Figur 3 wird eine Autobahnausfahrt aus der Perspektive des Fahrzeuglenkers gezeigt. Da es sich dabei um eine Gefahrenstelle handelt, werden um dem Fahrzeuglenker steigende Geschwindigkeit vorzutäuschen, die Abstände der aufeinander folgenden Sicherheitsüberzugselemente reduziert. Das geht bei der vorliegenden perspektivischen Darstellung daraus hervor, dass die Abstände der Leitplankentragspfosten als konstant zu betrachten sind.FIG. 3 shows a motorway exit from the driver's perspective. Since this is a danger point, the distance between the successive safety covering elements is reduced to simulate the driver's increasing speed. In the present perspective representation, this is evident from the fact that the distances between the guardrail support posts can be regarded as constant.

Die Figur 4 zeigt die rechte Seite der Autobahnausfahrt mit Sicherheitsüberzugselementen 1 gemäss Figur 2 von Leitplanken 11 aus der Perspektive eines Geisterfahrers, wobei die Signalflächen 10 mit Einbahnzeichen belegt sind um den Fahrzeuglenker auf seinen folgenschweren Fahrfehler aufmerksam zu machen.FIG. 4 shows the right side of the motorway exit with safety covering elements 1 according to FIG. 2 of guardrails 11 from the perspective of a ghost driver, the signal areas 10 being provided with one-way signs in order to draw the driver's attention to his serious driving errors.
