Description
Der Schrankenbaum als Hilfsmittel zur Verhütung von Verkehrsunfällen ist bekannt. Es hat sich jedoch gezeigt, daß Schrankenbäume der normalen Bauart übersehen werden kön-S nen, wenn der Führer eines Fahrzeuges durch das Scheinwerferlicht eines entgegenkommenden oder am Schrankenbaum haltenden Fahrzeuges geblendet ist.The barrier boom as an aid to contraception of traffic accidents is known. However, it has been shown that barrier booms the normal design can be overlooked when the driver of a vehicle by the headlights of an oncoming vehicle or a vehicle stopping at the boom is blinded.
Es sind deshalb Schrankenbäume geschaffen worden, die auf einer möglichst großen Fläche das Scheinwerferlicht entgegenkommender Fahrzeuge zurückhalten. Bei großen Flächen dieser Axt tritt aber dann die Schwierigkeit auf, daß Winde so erhebliche KräfteThere are therefore barrier booms have been created on the largest possible Area to hold back the headlights of oncoming vehicles. With big ones However, the difficulty arises on the surfaces of this ax that the winds have such considerable forces
!5 auf den Schrankenbaum ausüben können, daß einerseits die Betätigung des Schrankenbaums gefährdet ist, andererseits der Schrankenbaum im Hinblick auf diese großen Kräfte teuer und schwer ausfällt.! 5 can exercise on the boom that on the one hand the operation of the barrier boom is endangered, on the other hand the barrier boom is expensive and heavy in view of these large forces.
Es besteht deshalb das Bedürfnis nach einem Schrankenbaum, der den Vorteil der großen Fläche hinsichtlich des Lichtschutzes mit der Forderung nach geringem Luftwiderstand vereint. Dies wird gemäß der Erfindungdadurch erreicht, daß die Fläche aus einem Fächerwerk von sich gegenseitig überlappenden Blechen besteht. Eine besonders günstige Wirkung wird dann erzielt, wenn die sich überlappenden Bleche derart nach aerodynamischen Gesichtspunkten ausgestattet sind, daß der Luftwiderstand des Schrankenbaums wesentlich geringer ist als bei den bekannten vollwandigen oder sieb- bzw. netzartigen Ausführungen.There is therefore a need for a barrier boom that has the advantage of large area in terms of light protection with the requirement for low air resistance united. This is achieved according to the invention in that the surface consists of a framework of mutually overlapping Sheet metal. A particularly favorable effect is achieved when the overlapping metal sheets in such a way aerodynamic aspects are equipped that the air resistance of the barrier boom is much lower than with the known full-walled or sieve-like or net-like Executions.
Ein Ausführungsbeispiel der Erfindung ist "35 in Abb. 1 und 2 dargestellt. Die Fläche der Schranke ist in ein Fächerwerk von gleichartigen Leitblechen aufgelöst, die infolge der gegenseitigen Überlappung senkrecht auftreffendes Licht vollständig abschirmen. Im Gegensatz zum Licht aber kann die Luft den Krümmungen der Schaufeln folgen. Für Leitbleche, die die Strömung in gewünschter Wirkung um Krümmungen führen sollen, sind bauliche Richtlinien bekannt. Bei dem Ausführungsbeispiel der Erfindung sind diese Richtlinien nun berücksichtigt worden. Der Erfolg ist, daß ein solcher Strömungskanal selbst einen sehr geringen Luftwiderstand besitzt und deshalb auch der ganze Schrankenbaum dem Wind nur eine geringe Angriffsmöglichkeit bietet. An embodiment of the invention is shown in FIGS. 1 and 2 "35. The area of the Barrier is dissolved in a framework of similar guide plates, which as a result of the Completely shield the mutually overlapping light incident vertically. in the In contrast to light, however, the air can follow the curves of the blades. For baffles, building guidelines are known to guide the flow around bends in the desired effect. In the embodiment of the invention, these guidelines have now been taken into account. The success is that such a flow channel itself has a very low air resistance and therefore also the whole barrier boom offers the wind little chance of attack.
