Description
Vorrichtung zur Erhöhung der Sicherheit im Straßenverkehr mittels einer akustischen Signalvorrichtung eines Kraftfahrzeugs Die Erfindung betrifft eine Vorrichtung zur Erhöhung der Sicherung im Straßenverkehr mittels einer akustischen Signalvorrichtung eines Kraftfahrzeugs.Device for increasing road safety by means of an acoustic signal device of a motor vehicle The invention relates to a device to increase safety in road traffic by means of an acoustic Signal device of a motor vehicle.
Es ist bereits bekannt, eine akustische Signalvorrichtung, insbesondere für Kraftfahrzeuge, mittels des Bremshebels zu betätigen. Bei dieser bekannten Vorrichtung bringt ein in einem Zylinder gleitender Kolben bei einer bestimmten Bremsgeschwindigkeit ein Signal, z. B. ein Pfeifsignal, zum Ansprechen.It is already known an acoustic signal device, in particular for motor vehicles, to be operated by means of the brake lever. In this known device brings a piston sliding in a cylinder at a certain braking speed a signal, e.g. B. a whistle signal to respond.
Bei der bekannten Vorrichtung sitzt am hinteren Ende des Fahrzeuges ein Zylinder mit einer Austrittsöffnung für die durch den Zylinderkolben verdrängte Luft. Die Austrittsöffnung ist vom Führersitz regelbar.In the known device sits at the rear end of the vehicle a cylinder with an outlet opening for the displaced by the cylinder piston Air. The outlet opening can be regulated from the driver's seat.
In der Praxis konnte -sich diese Vorrichtung nicht durchsetzen, wahrscheinlich deswegen, weil die Betätigung des Bremshebels nicht genügt, daß durch das Ausströmen der Luft aus der Zylinderöffnung ein auch nur in nennenswerter Entfernung vom Kraftfahrzeug hörbarer Pfeifton entsteht.In practice, this device could not prevail, probably because the operation of the brake lever is not enough that by the leakage the air from the cylinder opening only at a significant distance from the motor vehicle audible whistling sound occurs.
Die Erfindung bezweckt die Schaffung einer Vorrichtung, welche zusätzlich zu dem durch die Straßenverkehrsordnung vorgeschriebenen Bremslicht dazu dient, um den Verkehrsteilnehmern anzuzeigen, daß der Fahrer die Bremße tätigt. Dies ist insbesondere auch dann von Wichtigkeit, wenn das Bremslicht ausfällt, ohne daß der Kraftfahrer dies bemerkt. Es gibt zwar Einrichtungen, welche den Ausfall des Bremslichtes dem Fahrer im Führerstand anzeigen, jedoch findet diese Einrichtung verhältnismäßig selten Verwendung.The invention aims to provide a device which additionally in addition to the brake light required by the road traffic regulations, to indicate to road users that the driver is applying the brake. This is especially important if the brake light fails without the Motorists noticed this. Although there are facilities that prevent the failure of the brake light show the driver in the driver's cab, however, this facility finds proportionate seldom use.
Es kann ferner, insbesondere bei schlechter Witterung und schlechten Straßenverhältnissen, vorkommen, daß das Bremslicht von außen so stark verschmutzt und verschmiert wird, dafi es nur noch auf geringe Entfernung erkennbar ist. Ferner wird die Erkennbarkeit des Auf leuchtens sehr stark beeinträchtigt bei Nebel und starkem Regen oder Schneefall. Gegen alle diese Störungen sind die normalen Maßnahmen, wie sie die Straßenverkehrsordnung vorschreibt, unwirksam.It can also, especially in bad weather and bad Road conditions, it can happen that the brake light is so strong from the outside dirty and is smeared so that it can only be seen at a short distance. Further the recognizability of the lights up is severely impaired in fog and heavy rain or snowfall. Against all these disturbances are the normal measures, as prescribed by the road traffic regulations, ineffective.
Unbestreitbar besteht aber ein dringendes. Be- dürfnis, die vorstehend erwähnten Gefahrenquellen nach Möglichkeit auszuschalten, insbesondere da die Wirksamkeit der modernen Bremsen isich immer mehr erhöht und infolgedessen auch die Bremswege sich immer mehr verkürzen. Bei -dem dichten Straßenverkehr -besteht daher die weitere erhebliche Gefahr, daß auch bei schärfster Aufmerksamkeit des Fahrers ein Auffahren des Kraftfahrzeuges sich zur Zeit nicht vermeiden läßt.But there is undeniably an urgent one. Off B e dürfnis, the hazards mentioned above, if possible, especially as more and more increases the effectiveness of modern brakes isich and consequently the braking distances are shortened more and more. In the dense traffic there is therefore the further considerable risk that, even with the driver's keenest attention, the motor vehicle can not be avoided at the moment.
Hier setzt die Erfindung ein und geht von idem Gedanken aus, den Kraftfahrer von der optischen Wahrnehmung der Bremsbetätigung eines Vordexmannes unabhängig zu machen, und zwar dadurch, daß diese optische Signalgebung- durch eine unüberhörbare akustische Signalgebung ergänzt wird. Der Erfindungszweck wird dadurch erreicht, daß die akustische Signalvorrichtung in der Auspuffleitung angeordnet bzw. mit ihr verbunden ist. Die technische Ausgestaltung .der Signaleinrichtung kann den jeweiligen Bedürfnissen sowohl der Tonerzeugung als auch den Verhältnissen des Kraftfahrzeuges selbst, z. B. des Personenwagens, weitgehend arngepaßt werden, ohne vom Grundgedanken der Erfindung .abzuweichen.This is where the invention comes in and is based on the same idea, the driver independent of the visual perception of the brake actuation of a Vordex man to make, namely by the fact that this optical signaling through an unmistakable acoustic signaling is added. The purpose of the invention is achieved by that the acoustic signal device is arranged in the exhaust pipe or with it connected is. The technical design of the signaling device can vary according to the respective Needs both the sound generation and the conditions of the motor vehicle itself, e.g. B. the passenger car, to be largely adapted without from the basic idea to deviate from the invention.
