Abstract
A roadway safety device, for example a crash barrier (8), is provided with a coating (10) in the places which are exposed in the event of a collision, the inner profile of the coating being adapted to the shape of the crash barrier. In this manner, a collision is damped so that the damage arising as a result of the impact can be effectively reduced. Old rubber in particular is suitable as the coating. <IMAGE>

PATENTANSPRÜCHE
1. Stossdämpfer an einer Fahrbahn-Sicherheitseinrichtung, dadurch gekennzeichnet, dass die Sicherheitseinrichtung an den bei einem Aufprall exponierten Stellen mit einem Belag (10-15, 24, 27) aus elastischem Material versehen ist, wobei das innere Profil des Belages der Form der Sicherheitseinrichtung angepasst ist.
2. Stossdämpfer gemäss Patentanspruch 1, dadurch gekennzeichnet, dass der Stossdämpfer ein Stahlrohr (21) aufweist, das um einen Pfosten (17) der Sicherheitseinrichtung geführt und beweglich ist.
3. Stossdämpfer nach Patentanspruch 2, dadurch gekennzeichnet, dass der Belag aus altem Gummi hergestellt ist.
4. Stossdämpfer nach Patentanspruch 1, an einer Leitplanke, dadurch gekennzeichnet, dass zwischen Pfosten (17) und Leitplanke (8, 9) ein Dämpfungselement (16) aus elastischem Material eingebaut ist.
5. Stossdämpfer nach Patentanspruch 4, dadurch gekennzeichnet, dass zwischen Pfosten (17) und Sockel (19) eine Gummieinlage (18) eingebaut ist.
6. Stossdämpfer nach Patentanspruch 1, an einem Einzelpfosten, dadurch gekennzeichnet, dass der Einzelpfosten (23) mit dem stossdämpfenden Belag mit einer von der inneren abweichenden äusseren Form umhüllt ist.
7. Stossdämpfer nach Patentanspruch 1, dadurch gekennzeichnet, dass das Querprofil des Belages schlauchförmig (10, 12, 14) ist.
Die Erfindung betrifft Stossdämpfer an Fahrbahn-Sicherheitseinrichtungen wie Geländern, Leitplanken, Pfosten, Wehrsteinen, Brücken- und Tunnelgeländern in Parkhäusern, sowie auch an anderen geeigneten Schutzeinrichtungen. Die Anwendung der Erfindung soll an exponierten Stellen Anprall von Fahrzeugen und dessen Folgen mildern.
Die bereits bekannten Stossdämpfersysteme, wie z.B. die federnden Stossdämpfersysteme, Stahlseile, Metallhüllen mit Schaumstoff-Füllung mit verschiedenen Kernformen usw.
haben den Nachteil. dass beim Anprall von Fahrzeugen Metall auf Metall stösst, was einen harten Anprall hervorruft. Ein weiterer Nachteil der bisher bekannten Einrichtungen ist der, dass diese ständige Instandhaltung und Kontrolle erfordern.
Manche sind technisch kompliziert und daher sehr kostspielig.
Diese und andere Nachteile der bekannten Einrichtungen werden durch die Erfindung gemäss den Merkmalen des Patentanspruches 1, beseitigt; durch eine stärkere Anpralldämpfung der Fahrzeuge auf die Fahrbahnschutzeinrichtungen bewirkt sie, dass der Anprall beträchtlich reduziert wird, wodurch die Unfallanfälligkeit der Fahrzeuginsassen, die Deformation der Fahrzeuge sowie die Demolierung der Sicherheitseinrichtungen vermindert wird.
Die Grundlage der Erfindung besteht darin, dass die Fahrbahn-Sicherheitseinrichtungen mit Gummi oder anderem elastischen Material umhüllt sind, welches beim Anprall einen beträchtlichen Teil der Energie für eigene Deformation verbraucht, so dass sich die Anprallkraft wesentlich verringert.
Ein kleinerer Anprallwinkelzwischen dem Fahrzeug und der Sicherheitseinrichtung führt zur Abbremsung und zum Stillstand des Fahrzeuges, so dass das Fahrzeug und die Sicherheitseinrichtungen intakt bleiben.
Der Dämpfungseffekt ist von der Dicke, Härte, Elastizität und Form des Belages abhängig. Durch vielfache Konstruktionsmöglichkeiten für das richtige Funktionieren ist jedes Dämpfungsproblem technisch lösbar. Die vorgeschlagenen Stossdämpfer können in verschiedenen Längen mit geeignetem Innenprofil so hergestellt werden, dass sie auch auf die bereits bestehenden Sicherheitseinrichtungen auf einfache Art befestigt werden können. Das Innenprofil kann selbsthaltend ausgeführt, auf den Kern angeklebt, vulkanisiert oder auf eine andere Art befestigt werden.
Ein weiterer Vorteil der Erfindung ist auch das geringe Gewicht und die gleichmässige Gewichtsverteilung des Dämpfers. Bei dem Umbau auf bereits bestehenden Planken kann daher der Pfostenabstand unverändert bleiben. Die Erfindung fordert keinen besonderen Schutz gegen Wettereinflüsse und kann in verschiedenen Farben, auch mit reflektierendem Material als Nachtkennzeichen, hergestellt werden, wie es in der Fahrbahn-Markierungstechnik üblich ist. Die Erfindung ist in folgender Beschreibung zu den Zeichnungen, die einige Ausführungsbeispiele darstellen, näher erläutert.
Die Fig. 1, 2, 3, 4, 5, veranschaulichen einige Stahlschutzplanken 8, 9, im Schnitt, umhüllt mit elastischem Belag 10, 11, 12, 13, 14, 15. Das Element 16, in Fig. 1, 2, und 5, ist ein elastischer Dämpfer, welcher zwischen dem Pfosten und der Schutzplanke 8, 9, zweckmässig angebracht wird. Fig. 1, veranschaulicht eine Belagform 10, mit gerippter Aussenfläche.
Eine weitere Ausführung, die den Anprall der Fahrzeuge in allen Richtungen reduzieren kann, ist in Fig. 4 dargestellt. Das Dämpfungselement 14, ist schlauchförmig, dessen Festigkeit mit Cordgewebe 29, und Stahldrahteinlage 30, erhöht ist und durch ein eingebautes Ventil 31, die Luft unter Druck eingepumpt werden kann.
Eine weitere Ausführung und Einsatzmöglichkeit des Dämpfers zeigt Fig. 1, in die der Pfosten 17, im Sockel 19, in eine elastische Masse 18, eingegossen ist. In den Fig. 1, 2, 3, 4, 5, angedeutete Ausführungen können auch einzeln oder in verschiedenen Kombinationen verwendet werden.
Eine weitere Ausbildung der Erfindung ist in Fig. 5 dargestellt. Der elastische Teil 20 ist mit einem Stahlrohrkern 21 verbunden. Diese Teile sind drehbar und in vertikaler Richtung beweglich.
Die Unfallanfälligkeit kann mit dem bis jetzt nicht angewandten Strassenpfostentyp laut Fig. 7 vermindert werden.
Auf den Pfosten 26 ist ein mit dem Dämpfer 27 umhülltes, grösseres Rohr 28 angesetzt, der rotieren und sich in vertikaler Richtung bewegen kann. Von aussen kann dieser Dämpfer zylindrisch, konisch oder anders geformt sein. Beim Anprall des Fahrzeuges auf einen solchen Pfosten unter einem kleinen Winkel, kann es ohne Beschädigung in die richtige Fahrbahn wieder zurückgesteuert werden.
Eine weitere Ausführung der Erfindung ist die Umhüllung der fixen Stahl-, Holz- und Betonstrassenpfosten mit elastischem Material laut Fig. 6. Die innere Form des Dämpfers ist dem Pfosten 23 angepasst. Von aussen kann der Dämpfer kantig 24 oder rund 25, sein.
Eine Weiterbildung der Erfindung wird durch die Verwendung von neubearbeiteten Abfallgummis und Altpneus zur Herstellung aller Arten der oben beschriebenen Stossdämpfer erreicht, die mit einer geeigneten Technologie serienmässig fabriziert werden können.

PATENT CLAIMS
1. Shock absorber on a roadway safety device, characterized in that the safety device is provided at the points exposed to an impact with a covering (10-15, 24, 27) made of elastic material, the inner profile of the covering being in the form of the safety device is adjusted.
2. Shock absorber according to claim 1, characterized in that the shock absorber has a steel tube (21) which is guided and movable around a post (17) of the safety device.
3. Shock absorber according to claim 2, characterized in that the covering is made of old rubber.
4. Shock absorber according to claim 1, on a guardrail, characterized in that a damping element (16) made of elastic material is installed between the post (17) and the guardrail (8, 9).
5. Shock absorber according to claim 4, characterized in that between the post (17) and base (19) a rubber insert (18) is installed.
6. Shock absorber according to claim 1, on a single post, characterized in that the single post (23) is encased with the shock-absorbing covering with an outer shape deviating from the inner.
7. Shock absorber according to claim 1, characterized in that the transverse profile of the covering is tubular (10, 12, 14).
The invention relates to shock absorbers on roadway safety devices such as railings, crash barriers, posts, weir stones, bridge and tunnel railings in parking garages, and also on other suitable protective devices. The application of the invention is intended to mitigate the impact of vehicles and their consequences at exposed locations.
The already known shock absorber systems, such as the resilient shock absorber systems, steel cables, metal sleeves with foam filling with different core shapes etc.
have the disadvantage. that metal collides with metal when it hits a vehicle, causing a hard impact. Another disadvantage of the previously known devices is that they require constant maintenance and control.
Some are technically complicated and therefore very expensive.
These and other disadvantages of the known devices are eliminated by the invention according to the features of claim 1; by increasing the impact damping of the vehicles on the roadway protection devices, it has the effect that the impact is considerably reduced, thereby reducing the susceptibility of the vehicle passengers to accidents, the deformation of the vehicles and the demolition of the safety devices.
The basis of the invention is that the roadway safety devices are encased in rubber or other elastic material, which uses a considerable part of the energy for its own deformation in the event of an impact, so that the impact force is significantly reduced.
A smaller impact angle between the vehicle and the safety device leads to braking and to a standstill of the vehicle, so that the vehicle and the safety devices remain intact.
The damping effect depends on the thickness, hardness, elasticity and shape of the covering. Due to the numerous design options for the correct functioning, every damping problem can be solved technically. The proposed shock absorbers can be manufactured in various lengths with a suitable inner profile in such a way that they can also be easily attached to the already existing safety devices. The inner profile can be self-holding, glued to the core, vulcanized or attached in any other way.
Another advantage of the invention is the low weight and the even weight distribution of the damper. When converting to existing planks, the post spacing can therefore remain unchanged. The invention does not require any special protection against the effects of the weather and can be produced in various colors, even with reflective material as a night indicator, as is customary in road marking technology. The invention is explained in more detail in the following description of the drawings, which illustrate some exemplary embodiments.
1, 2, 3, 4, 5, illustrate some steel protective planks 8, 9, in section, covered with elastic covering 10, 11, 12, 13, 14, 15. The element 16, in Fig. 1, 2, and 5, is an elastic damper, which is conveniently attached between the post and the crash barrier 8, 9. Fig. 1, illustrates a covering mold 10, with a ribbed outer surface.
Another embodiment which can reduce the impact of the vehicles in all directions is shown in FIG. 4. The damping element 14 is tubular, the strength of which is increased with cord fabric 29 and steel wire insert 30, and by means of a built-in valve 31, the air can be pumped in under pressure.
A further embodiment and possible use of the damper is shown in FIG. 1, in which the post 17, in the base 19, is cast in an elastic mass 18. 1, 2, 3, 4, 5, indicated versions can also be used individually or in different combinations.
Another embodiment of the invention is shown in FIG. 5. The elastic part 20 is connected to a steel tube core 21. These parts are rotatable and movable in the vertical direction.
The susceptibility to accidents can be reduced with the type of road post according to FIG. 7 which has not yet been used.
On the post 26, a larger tube 28, which is covered with the damper 27, is attached, which can rotate and move in the vertical direction. From the outside, this damper can be cylindrical, conical or shaped differently. If the vehicle collides with such a post at a small angle, it can be steered back into the correct lane without being damaged.
Another embodiment of the invention is the covering of the fixed steel, wood and concrete road posts with elastic material according to FIG. 6. The inner shape of the damper is adapted to the post 23. From the outside, the damper can be angular 24 or around 25.
A further development of the invention is achieved through the use of newly processed rubbers and old tires for the production of all types of the shock absorbers described above, which can be mass-produced with a suitable technology.
