Definitions
- the present invention relates to a mechanically operable distance warning device for displaying a distance between a vehicle and an obstacle, comprising at least two rods, which are arranged in a receiving part.
- deformable, energy-absorbing plates or sheets are attached to the walls of the garage.
- old car tires are often used for this purpose, which have a comparable effect.
- Such energy absorbing parts have the disadvantage, however, that they have to be attached to the wall in accordance with the body shape of the vehicle and in particular the height of the front vehicle bumpers in order to be able to reduce the consequences of a collision of the vehicle with the wall.
- Such energy-absorbing parts only develop their damping effect if they are sufficiently dimensioned. This means that only then can a substantial part of impact energy be converted into deformation energy of the energy-absorbing parts. The excess energy is also partially converted into deformation energy of the vehicle and thereby causes plastic and therefore irreversible deformations of the vehicle or individual vehicle parts.
- German utility model G 86 27 071.0 and Japanese laid-open patent publication JP 2001081998 A show relatively simple embodiments of a mechanical actuatable distance warning. Both include a base with an upstanding spring, in the top opening of which a rod is attached. Due to the connection with the spring, the rod assumes an essentially vertical position in its rest position and can be pivoted in practically any direction by the action of an external force. A reflector is provided at an upper end of the rod for better visibility.
- a further embodiment of a mechanically actuated distance warning device is shown in German laid-open specification DE 100 49 850 A1, in which a rod is fastened in a plug-in receiver of a carrier, which is set up on the bottom.
- This distance warning device is designed so that it is tilted when an external force is applied.
- the German utility model G 85 00 490.1 discloses a mechanically actuated distance warning device of the type mentioned at the outset.
- This distance warning device comprises several rods, which are arranged in a receiving part. A critical distance of the vehicle from a wall is signaled to the driver by a change in the height of a display part attached to the wall in a guide. The movements of the rods are coupled to one another via several joint mechanisms and are therefore not independent of one another and in this way cause the height of the display part to change.
- the object of the present invention is to provide a vehicle-independent, mechanically operable generic distance warning device which reliably warns the driver of a vehicle of a collision with an obstacle and, moreover, has a mechanically simple structure and is therefore robust and almost maintenance-free.
- the distance warning device comprises at least two rods, which are arranged in a receiving part and can be moved independently of one another.
- An external force that a vehicle exerts when it touches the rods of the distance warning device causes the rods to move from their unloaded rest position, the movement of the rods being independent of one another according to the invention.
- the movement as such immediately signals to the driver that part of his vehicle is currently touching the rods of the distance warning device. In this way, a collision of the vehicle with the obstacle can be avoided if the driver perceives the movement of the rods of the distance warning device in good time and responds accordingly.
- the advantage of the solution according to the invention that at least two rods can be moved independently of one another is that the driver of the vehicle can perceive them more easily than just one movable rod.
- the independent mobility of the rods considerably simplifies the mechanical construction of the distance warning device, since no coupling joints are required. Furthermore, the distance warning device can still be used if a rod is defective.
- a particularly preferred embodiment provides that the rods are arranged pivotably relative to the obstacle.
- the pivotability of the rods creates a simple possibility to convert the kinetic energy of the vehicle that touches the distance warning device into kinetic energy of the rods.
- the collision protection function of the distance warning device is considerably improved.
- the extent of the pivotability of the rods should be designed so that there is sufficient buffer between the rods in their rest positions and their end positions in the area of the obstacle. Furthermore, the pivoting movement has proven to be particularly well recognizable for the driver.
- the receiving part comprises a tilt-stable base.
- the tilt stability of the base ensures that the distance warning device remains stable even when an external force is applied.
- the distance warning device can be moved very easily to another location, particularly if additional anchoring or fastening means are dispensed with.
- the use of the distance warning device is not limited to a specific location.
- the receiving part for the rods of the distance warning device can be attached to the obstacle.
- the receiving part can be attached essentially at the bottom, with at least two rods extending upward from the receiving part in order to be visible to the driver.
- the receiving part of the distance warning device can comprise a plurality of bores so that it can be reliably fastened to a wall or to another obstacle with the aid of suitable fastening means (e.g. screws or bolts).
- the receiving part of the distance warning device can be fastened on the base side.
- the receiving part of the distance warning device can comprise a plurality of bores on its underside in order to enable anchoring in the ground with the aid of suitable fastening means.
- the receiving part can also be designed so that both a bottom-side attachment and an attachment to the obstacle is possible.
- a particularly advantageous embodiment provides that two bars in their rest positions are arranged essentially in a V-shape with respect to one another in the receiving part without the force being exerted by the vehicle and enclose an angle with one another, and that the receiving part has guides in which the rods can be moved in such a way that the angle enclosed between the rods is reduced when a force exerted by a part of the vehicle is applied.
- the A change in the angle of the rods relative to one another has the effect that a change in the distance between his vehicle and the obstacle is signaled to the driver.
- the two rods move under the action of an external force exerted by the vehicle from their V-shaped rest position along their guides in the receiving part in such a way that the angle enclosed between them decreases.
- the angle between the two rods becomes smaller the smaller the distance between the distance warning device or the vehicle and the obstacle.
- the size of the angle between the two poles thus represents a measure of the instantaneous distance between the vehicle and the obstacle.
- the smaller the angle enclosed between the two poles the smaller the distance between the vehicle and the obstacle.
- the two rods In their end position, the two rods can be aligned almost parallel to one another and can also touch the obstacle in this position.
- the rods of the distance warning device are designed to be relatively rigid, this can have the consequence that when the essentially obstacle-side end position of the rods is reached, additional force action leads to parts of the vehicle and in particular the sections of the vehicle bumper which are in direct contact with the rods , locally exposed to a relatively high pressure and can therefore be plastically and thus irreversibly deformed.
- the rods of the distance warning device can also break due to the application of additional force and thus become unusable.
- An advantageous embodiment therefore provides for the rods of the distance warning device itself to be energy-absorbing. This can be achieved in that the rods are made of flexible material at least in sections.
- a preferred embodiment of the distance warning device provides that the rods comprise several parts which are detachably connected to one another.
- the detachable connection of the parts can be implemented, for example, as a plug connection. This embodiment facilitates the transport of the distance warning device and allows defective parts to be replaced with a relatively small amount of assembly work.
- Vehicles are made in different sizes. They differ, among other things, by the vehicle height and very often also by the driver's seat height, which is generally lower, for example, in a small car than in a van or truck.
- a particularly expedient embodiment provides for the rods of the distance warning device to be designed to be extendable. This allows the length of the bars to be modified in a simple manner and adapted to different vehicle sizes or seat heights of the driver.
- the rods can be designed as telescopic rods. Such telescopic rods allow particularly easy handling of the height adjustment.
- a further embodiment provides that at least one of the rods has light-reflecting sections. This will make it Drivers, especially in the dark, are relieved to recognize the poles illuminated by the headlights of the vehicle.
- a further embodiment provides that at least one of the rods of the distance warning device has at least one signal device.
- the signaling device can preferably be attached to an upper rod section facing the receiving part in order to make it easier for the driver to recognize it.
- the color of the signaling device can be selected so that it further improves the visibility of the distance warning device.
- a further embodiment provides that light-reflecting sections are attached to the signaling device. These are preferably attached to outer parts of the signaling device facing the driver. Such light-reflecting sections improve the perception of the approach of the vehicle to the distance warning device, especially in the dark, because the light of the vehicle headlights is reflected by these sections.
- a further embodiment provides that the signal device has means for transmitting acoustic signals. If the movement of the rods of the distance warning device exceeds a certain threshold, an acoustic signal is generated.
- the pitch and / or the signal repetition frequency of the acoustic signal can be dependent on the current position of the rods relative to each other and / or relative to the obstacle can be varied.
- an embodiment of the distance warning device is particularly advantageous, the signaling device of which comprises means for transmitting optical signals. These optical signals can only serve to illuminate the distance warning device. However, you can also warn the driver of a collision of the vehicle with the obstacle by means of different colors and / or signal repetition frequencies depending on the distance of the bars from the obstacle or depending on the angle enclosed between the bars.
- the distance warning device comprises resetting means which move the rods back into their starting position. These restoring means also cause the rods of the distance warning device to be biased in their rest position by an additional force. This creates an additional resistance, which must be overcome by the force exerted by the vehicle from the outside before the rods start to move.
- the resetting means are preferably attached in the receiving part of the distance warning device.
- the restoring means comprise at least one compression spring.
- the use of at least one compression spring which can be made of metal, for example, ensures the restoring effect even when the distance warning device is used frequently.
- the at least one compression spring can be attached within the receiving part in the region of the guides of the rods or directly on the rods.
- a further advantageous embodiment provides that the resetting means have at least one leaf spring.
- Leaf springs are relatively easy and inexpensive to manufacture and retain their restoring effect even with frequent use.
- the at least one leaf spring can be attached within the receiving part in the region of the guides of the rods or directly on the rods.
- the at least one leaf spring can consist of metal at least in sections. But it can also be designed as a plastic or fiberglass leaf spring.
- the plastic leaf spring can be an integral part of the receiving part, wherein the receiving part and the plastic leaf spring can be produced in particular by a conventional injection molding process.
- FIG. 1 There, the distance warning device 1 according to the invention, in front of which there is a vehicle, is shown in a side view.
- the distance warning device comprises two rods 2, 3 which can be moved independently of and relative to one another and relative to a wall 7 (cf. also FIGS. 2 and 3), which are arranged in a receiving part 4.
- the receiving part 4 of the distance warning device 1 is attached directly to the wall 7.
- the rods 2, 3 of the distance warning device can be constructed, at least in sections, from materials that do not cause any paint damage to the vehicle 8 when it comes into contact with it. For this purpose, it makes sense to make the rods completely, at least on their surfaces and in particular in the areas that can come into contact with parts of the vehicle 8, from smooth and paint-protecting plastic.
- signal devices are provided at the upper ends of rods 2, 3, which are again shown explicitly in FIGS. 2 and 3.
- the signaling devices 5, 6 can only consist of a part covered with a signal color.
- they can be light-reflecting at least in sections and have means for transmitting optical and / or acoustic signals.
- the rods 2, 3 of the distance warning device 1 can have light-reflecting materials, at least in sections, on their surface, which considerably facilitate the detection of the distance warning device 1 when approaching, especially in poor visibility conditions.
- the rods 2, 3 of the distance warning device 1 are mounted in the receiving part 4 in such a way that, starting from their rest position, they are oriented in their end position essentially parallel to the wall 7.
- 4 resetting means are provided in the receiving part (not explicitly shown here), which can have compression springs and / or leaf springs.
- FIG. 2 shows a front view of the distance warning device 1 in an unloaded state, that is to say in a state in which no force from a vehicle 8 acts on the distance warning device 1.
- the rods 2, 3, which each have a signal device 5, 6 at their upper ends, are arranged in this rest position in the receiving part 4 in a substantially V-shaped manner.
- the receiving part 4 of the distance warning device 1 is fixed to the wall 7 shown in FIG. 1 with a plurality of fastening means 9.
- the receiving part 4 can also be made sufficiently stable so that it is not necessary to fix the receiving part 4 to the wall 7.
- FIG. 3 finally shows a further front view of the distance warning device, in which case the distance warning device is acted upon by an external force. It can be clearly seen that the two rods 2, 3 of the distance warning device are now aligned almost parallel to one another. This also corresponds to an almost parallel position of the rods 2, 3 of the distance warning device 1 relative to the wall 7 in FIG. 1. So that the two rods 2, 3 can perform the movement from an essentially V-shaped rest position, as shown in FIG. 2, to an almost parallel position according to FIG. not explicitly shown) provided.

Abstract
Description
Die vorliegende Erfindung betrifft eine mechanisch betätigbare Abstandswarnvorrichtung zur Anzeige eines Abstands zwischen einem Fahrzeug und einem Hindernis, umfassend mindestens zwei Stangen, die in einem Aufnahmeteil angeordnet sind.The present invention relates to a mechanically operable distance warning device for displaying a distance between a vehicle and an obstacle, comprising at least two rods, which are arranged in a receiving part.
Heutzutage orientiert sich das Design von Fahrzeugen überwiegend an ästhetischen und/oder an aerodynamischen Vorgaben. Eine solche auf einen möglichst geringen Luftwiderstandswert optimierte Linienführung moderner Fahrzeugkarosserien erschwert jedoch häufig das Einparken des Fahrzeugs, da selbst verhältnismäßig großgewachsene Fahrer die vorderen und hinteren Bereiche des Fahrzeugs nicht mehr optimal einsehen und überblicken können. Insbesondere beim Einparken des Fahrzeuges in einer Garage, Tiefgarage oder ganz allgemein vor Wänden erweist sich eine unübersichtliche Ausführung der Fahrzeugkarosserie als nachteilig. Verschätzt sich der Fahrer hinsichtlich der Ausmaße seines Fahrzeugs, kann eine front- oder heckseitige Kollision mit einer Wand oder einem anderen massiven Hindernis schon bei relativ geringen Fahrzeuggeschwindigkeiten zu irreversiblen Beschädigungen des Fahrzeugs führen, die unter Umständen langwierige und kostspielige Reparaturen zur Folge haben können.Nowadays, the design of vehicles is mainly based on aesthetic and / or aerodynamic requirements. However, such lines of modern vehicle bodies, which have been optimized for the lowest possible aerodynamic drag, often make parking the vehicle more difficult, since even relatively tall drivers can no longer optimally see and view the front and rear areas of the vehicle. In particular when parking the vehicle in a garage, underground car park or in general in front of walls, a confusing design of the vehicle body proves to be disadvantageous. If the driver misjudges the size of his vehicle, a front or rear collision with a wall or other massive obstacle can lead to irreversible damage to the vehicle even at relatively low vehicle speeds, which can result in lengthy and costly repairs.
Um diesem Problem zu begegnen hat die Industrie mittlerweile elektronische Systeme mit Ultraschallsensoren entwickelt, die den Fahrer eines Fahrzeugs mit Hilfe von akustischen Signalen warnen, wenn beispielsweise beim Rückwärtsfahren eine Kollision mit einem Hindernis (z.B. mit einer Wand oder einem anderen Fahrzeug) droht. Die wesentlichen Nachteile derartiger Abstandssensoren bestehen darin, dass sie in ihrer Herstellung relativ teuer sind und zudem eine komplizierte und zeitaufwendige Montage im Bereich der Stoßfänger des Fahrzeuges erfordern. Vor allem bei älteren Fahrzeugen ist eine Nachrüstung mit elektronischen Abstandssensoren aufwendig und entsprechend kostenintensiv, da außerdem ein Eingriff in die Fahrzeugelektronik notwendig ist.In order to counter this problem, the industry has meanwhile developed electronic systems with ultrasonic sensors which warn the driver of a vehicle with the aid of acoustic signals if, for example, a collision with an obstacle (for example with a wall or another vehicle) threatens when reversing. The main disadvantages of such distance sensors are that they are relatively expensive to manufacture and also require a complicated and time-consuming assembly in the area of the vehicle's bumper. In older vehicles in particular, retrofitting with electronic distance sensors is complex and Correspondingly expensive, since an intervention in the vehicle electronics is also necessary.
Um die Folgen einer frontseitigen Kollision des Fahrzeugs mit einer (stirnseitigen) Garagenwand zu reduzieren, werden sehr häufig verformbare, energieabsorbierende Platten oder Bahnen, wie sie beispielsweise aus dem deutschen Gebrauchsmuster DE 299 16 563 U1 bekannt geworden sind, an den Wänden der Garage angebracht. Häufig werden zu diesem Zweck aus Kostengründen auch alte Autoreifen benutzt, die eine vergleichbare Wirkung erzielen. Derartige energieabsorbierende Teile haben allerdings den Nachteil, dass sie der Karosserieform des Fahrzeugs und insbesondere der Höhe der frontseitigen Fahrzeugstoßfänger entsprechend an der Wand angebracht sein müssen, um die Folgen einer Kollision des Fahrzeuges mit der Wand vermindern zu können. Ihre dämpfende Wirkung entfalten solche energieabsorbierenden Teile nur, wenn sie ausreichend dimensioniert sind. Das bedeutet, dass nur dann ein wesentlicher Teil Aufprallenergie in Verformungsenergie der energieabsorbierenden Teile umgewandelt werden kann. Die überschüssige Energie wird teilweise auch in Verformungsenergie des Fahrzeugs umgewandelt und verursacht dadurch plastische und damit irreversible Verformungen des Fahrzeugs bzw. einzelner Fahrzeugteile.In order to reduce the consequences of a front collision of the vehicle with a (front) garage wall, deformable, energy-absorbing plates or sheets, as are known, for example, from German utility model DE 299 16 563 U1, are attached to the walls of the garage. For reasons of cost, old car tires are often used for this purpose, which have a comparable effect. Such energy absorbing parts have the disadvantage, however, that they have to be attached to the wall in accordance with the body shape of the vehicle and in particular the height of the front vehicle bumpers in order to be able to reduce the consequences of a collision of the vehicle with the wall. Such energy-absorbing parts only develop their damping effect if they are sufficiently dimensioned. This means that only then can a substantial part of impact energy be converted into deformation energy of the energy-absorbing parts. The excess energy is also partially converted into deformation energy of the vehicle and thereby causes plastic and therefore irreversible deformations of the vehicle or individual vehicle parts.
Aus dem Stand der Technik sind auch unterschiedlich ausgeführte mechanisch betätigbare Abstandswarner bekannt, die nicht am Fahrzeug angebracht sind, und dem Fahrer trotzdem einen kritischen Abstand seines Fahrzeugs zu einem Hindernis signalisieren.Different mechanically actuated distance warning devices are also known from the prior art, which are not attached to the vehicle and nevertheless signal the driver a critical distance of his vehicle from an obstacle.
Beispielsweise zeigen das deutsche Gebrauchsmuster G 86 27 071.0 und die japanische Offenlegungsschrift JP 2001081998 A verhältnismäßig einfache Ausführungsformen eines mechanisch betätigbaren Abstandswarners. Beide umfassen einen Standfuß mit einer nach oben ragenden Feder, in deren oberseitiger Öffnung eine Stange befestigt ist. Durch die Verbindung mit der Feder nimmt die Stange in ihrer Ruhelage eine im Wesentlichen vertikale Position ein und kann durch Einwirken einer äußeren Kraft in praktisch jede beliebige Richtung verschwenkt werden. An einem oberen Ende der Stange ist zur besseren Sichtbarkeit ein Reflektor vorgesehen.For example, German utility model G 86 27 071.0 and Japanese laid-open patent publication JP 2001081998 A show relatively simple embodiments of a mechanical actuatable distance warning. Both include a base with an upstanding spring, in the top opening of which a rod is attached. Due to the connection with the spring, the rod assumes an essentially vertical position in its rest position and can be pivoted in practically any direction by the action of an external force. A reflector is provided at an upper end of the rod for better visibility.
Eine weitere Ausführungsform eines mechanisch betätigbaren Abstandswarners zeigt die deutsche Offenlegungsschrift DE 100 49 850 A1, in der eine Stange in einem Steckaufnehmer eines Trägers befestigt ist, der bodenseitig aufgestellt wird. Dieser Abstandswarner ist so aufgebaut, dass er beim Einwirken einer äußeren Kraft verkippt wird.A further embodiment of a mechanically actuated distance warning device is shown in German laid-open specification DE 100 49 850 A1, in which a rod is fastened in a plug-in receiver of a carrier, which is set up on the bottom. This distance warning device is designed so that it is tilted when an external force is applied.
Eine mechanisch betätigbare Abstandswarnvorrichtung der eingangs genannten Art offenbart das deutsche Gebrauchsmuster G 85 00 490.1. Dieser Abstandswarner umfasst mehrere Stangen, die in einem Aufnahmeteil angeordnet sind. Ein kritischer Abstand des Fahrzeugs von einer Wand wird dem Fahrer durch eine Veränderung der Höhe eines wandseitig in einer Führung angebrachten Anzeigeteils signalisiert. Die Bewegungen der Stangen sind dabei über mehrere Gelenkmechanismen miteinander gekoppelt und somit nicht unabhängig voneinander und bewirken auf diese Weise die Höhenänderung des Anzeigeteils.The German utility model G 85 00 490.1 discloses a mechanically actuated distance warning device of the type mentioned at the outset. This distance warning device comprises several rods, which are arranged in a receiving part. A critical distance of the vehicle from a wall is signaled to the driver by a change in the height of a display part attached to the wall in a guide. The movements of the rods are coupled to one another via several joint mechanisms and are therefore not independent of one another and in this way cause the height of the display part to change.
Wesentliche Nachteile dieser aus dem Stand der Technik bekannt gewordenen mechanisch betätigbaren Abstandswarnvorrichtungen bestehen darin, dass sie ihre Warnfunktion nicht immer zuverlässig erfüllen und teilweise, insbesondere bei Verwendung mehrerer miteinander gekoppelter Stangen, mechanisch aufwendig aufgebaut und damit störungsanfällig sind und demzufolge eine häufige Wartung erfordern.Significant disadvantages of these mechanically actuated distance warning devices, which have become known from the prior art, are that they do not always reliably perform their warning function and, in particular when using a plurality of rods which are coupled to one another, are mechanically complex and are therefore prone to failure and therefore require frequent maintenance.
Hier setzt nun die vorliegende Erfindung an.This is where the present invention begins.
Aufgabe der vorliegenden Erfindung ist es, eine fahrzeugunabhängige, mechanisch betätigbare gattungsgemäße Abstandswarnvorrichtung zur Verfügung zu stellen, die den Fahrer eines Fahrzeugs zuverlässig vor einer Kollision mit einem Hindernis warnt und darüber hinaus mechanisch einfach aufgebaut und somit robust und nahezu wartungsfrei ist.The object of the present invention is to provide a vehicle-independent, mechanically operable generic distance warning device which reliably warns the driver of a vehicle of a collision with an obstacle and, moreover, has a mechanically simple structure and is therefore robust and almost maintenance-free.
Diese Aufgabe wird gelöst durch eine Abstandswarnvorrichtung der eingangs genannten Art mit den kennzeichnenden Merkmalen des Anspruchs 1.This object is achieved by a distance warning device of the type mentioned at the outset with the characterizing features of claim 1.
Die erfindungsgemäße Abstandswarnvorrichtung umfasst mindestens zwei Stangen, die in einem Aufnahmeteil angeordnet und unabhängig voneinander bewegbar sind. Eine äußere Kraft, die ein Fahrzeug bei einer Berührung auf die Stangen der Abstandswarnvorrichtung ausübt, ruft eine Bewegung der Stangen aus ihrer unbelasteten Ruheposition hervor, wobei erfindungsgemäß die Bewegung der Stangen unabhängig voneinander ist. Die Bewegung als solche signalisiert dem Fahrer unmittelbar, dass ein Teils seines Fahrzeug momentan die Stangen der Abstandswarnvorrichtung berührt. Auf diese Weise kann eine Kollision des Fahrzeugs mit dem Hindernis vermieden werden, wenn der Fahrer die Bewegung der Stangen der Abstandswarnvorrichtung rechtzeitig wahrnimmt und darauf entsprechend reagiert. Der Vorteil der erfindungsgemäßen Lösung, dass mindestens zwei unabhängig voneinander bewegbare Stangen vorgesehen sind, liegt darin, dass sie vom Fahrer des Fahrzeugs einfacher wahrgenommen werden können als lediglich eine bewegbare Stange. Darüber hinaus vereinfacht die unabhängige Bewegbarkeit der Stangen den mechanischen Aufbau der Abstandswarnvorrichtung erheblich, da keine Kopplungsgelenke erforderlich sind. Ferner kann bei einem Defekt einer Stange die Abstandswarnvorrichtung trotzdem weiterverwendet werden.The distance warning device according to the invention comprises at least two rods, which are arranged in a receiving part and can be moved independently of one another. An external force that a vehicle exerts when it touches the rods of the distance warning device causes the rods to move from their unloaded rest position, the movement of the rods being independent of one another according to the invention. The movement as such immediately signals to the driver that part of his vehicle is currently touching the rods of the distance warning device. In this way, a collision of the vehicle with the obstacle can be avoided if the driver perceives the movement of the rods of the distance warning device in good time and responds accordingly. The advantage of the solution according to the invention that at least two rods can be moved independently of one another is that the driver of the vehicle can perceive them more easily than just one movable rod. In addition, the independent mobility of the rods considerably simplifies the mechanical construction of the distance warning device, since no coupling joints are required. Furthermore, the distance warning device can still be used if a rod is defective.
Eine besonders bevorzugte Ausführungsform sieht vor, dass die Stangen relativ zum Hindernis schwenkbar angeordnet sind. Durch die Schwenkbarkeit der Stangen wird eine einfache Möglichkeit geschaffen, um die Bewegungsenergie des Fahrzeugs, das die Abstandswarnvorrichtung berührt, in Bewegungsenergie der Stangen umzuwandeln. Insgesamt wird dadurch, abhängig von der Neigung der Stangen der relativ zum Hindernis in ihren Ruhelagen (d.h. ohne Krafteinwirkung von außen), die Kollisionsschutzfunktion der Abstandswarnvorrichtung erheblich verbessert. Der Umfang der Schwenkbarkeit der Stangen sollte dabei so ausgelegt sein, dass ein ausreichender Puffer zwischen den Stangen in ihren Ruhelagen und ihren Endpositionen im Bereich des Hindernisses gegeben ist. Ferner hat sich die Schwenkbewegung als für den Fahrer besonders gut erkennbar erwiesen.A particularly preferred embodiment provides that the rods are arranged pivotably relative to the obstacle. The pivotability of the rods creates a simple possibility to convert the kinetic energy of the vehicle that touches the distance warning device into kinetic energy of the rods. Overall, depending on the inclination of the rods relative to the obstacle in their rest positions (i.e. without external force), the collision protection function of the distance warning device is considerably improved. The extent of the pivotability of the rods should be designed so that there is sufficient buffer between the rods in their rest positions and their end positions in the area of the obstacle. Furthermore, the pivoting movement has proven to be particularly well recognizable for the driver.
Um die Abstandswarnvorrichtung an unterschiedlichen Orten einsetzen zu können, sieht eine vorteilhafte Ausführungsform vor, dass das Aufnahmeteil einen kippstabilen Sockel umfasst. Die Kippstabilität des Sockels sorgt auch bei Einwirken einer äußeren Kraft für einen sicheren Stand der Abstandswarnvorrichtung. Ferner kann, insbesondere bei Verzicht auf zusätzliche Verankerungs- bzw. Befestigungsmittel, die Abstandswarnvorrichtung sehr leicht an einen anderen Ort verbracht werden. Somit ist die Verwendung der Abstandswarnvorrichtung nicht auf ein auf einen bestimmten Ort beschränkt.In order to be able to use the distance warning device at different locations, an advantageous embodiment provides that the receiving part comprises a tilt-stable base. The tilt stability of the base ensures that the distance warning device remains stable even when an external force is applied. Furthermore, the distance warning device can be moved very easily to another location, particularly if additional anchoring or fastening means are dispensed with. Thus, the use of the distance warning device is not limited to a specific location.
Zur Vereinfachung der Montage ist es vorteilhaft, dass das Aufnahmeteil für die Stangen der Abstandswarnvorrichtung am Hindernis anbringbar ist. Die Anbringung des Aufnahmeteils kann im wesentlichen bodenseitig erfolgen, wobei sich mindestens zwei Stangen aus dem Aufnahmeteil nach oben hin erstrecken, um für den Fahrer sichtbar zu sein. Das Aufnahmeteil der Abstandswarnvorrichtung kann in dieser Ausführungsform eine Mehrzahl von Bohrungen umfassen, damit es mit Hilfe geeigneter Befestigungsmittel (z.B. Schrauben oder Bolzen) zuverlässig an einer Wand oder an einem anderen Hindernis befestigt werden kann.To simplify the assembly, it is advantageous that the receiving part for the rods of the distance warning device can be attached to the obstacle. The receiving part can be attached essentially at the bottom, with at least two rods extending upward from the receiving part in order to be visible to the driver. In this embodiment, the receiving part of the distance warning device can comprise a plurality of bores so that it can be reliably fastened to a wall or to another obstacle with the aid of suitable fastening means (e.g. screws or bolts).
In einer weiteren vorteilhaften Ausführungsform ist das Aufnahmeteil der Abstandswarnvorrichtung bodenseitig befestigbar. Diese Ausführungsform ist besonders dann vorteilhaft, wenn das Hindernis wegen seiner Beschaffenheit nicht für die Befestigung des Aufnahmeteils der Abstandswarnvorrichtung geeignet ist. In dieser Ausführungsform kann das Aufnahmeteil der Abstandswarnvorrichtung an seiner Unterseite eine Mehrzahl von Bohrungen umfassen, um mit Hilfe geeigneter Befestigungsmittel eine Verankerung im Boden zu ermöglichen. Das Aufnahmeteil kann auch so ausgeführt sein, dass sowohl eine bodenseitige Befestigung als auch eine Befestigung am Hindernis möglich ist.In a further advantageous embodiment, the receiving part of the distance warning device can be fastened on the base side. This embodiment is particularly advantageous if, due to its nature, the obstacle is not suitable for fastening the receiving part of the distance warning device. In this embodiment, the receiving part of the distance warning device can comprise a plurality of bores on its underside in order to enable anchoring in the ground with the aid of suitable fastening means. The receiving part can also be designed so that both a bottom-side attachment and an attachment to the obstacle is possible.
Um dem Fahrer das Erkennen der Annäherung seines Fahrzeugs an das Hindernis weiter zu erleichtern, sieht eine besonders vorteilhafte Ausführungsform vor, dass zwei Stangen in ihren Ruhelagen ohne Krafteinwirkung durch das Fahrzeugs im Aufnahmeteil im wesentlichen V-förmig zueinander angeordnet sind und miteinander einen Winkel einschließen, und dass das Aufnahmeteil Führungen aufweist, in denen die Stangen so bewegbar sind, dass sich der zwischen den Stangen eingeschlossene Winkel bei Einwirken einer von einem Teil des Fahrzeugs ausgeübten Kraft verringert. Die Winkeländerung der Stangen relativ zueinander bewirkt, dass dem Fahrer eine Änderung des Abstand zwischen seinem Fahrzeug und dem Hindernis signalisiert wird. Die beiden Stangen bewegen sich in dieser Ausführungsform beim Einwirken einer äußeren, vom Fahrzeug ausgeübten Kraft aus ihrer V-förmigen Ruheposition entlang ihrer Führungen im Aufnahmeteil in der Weise, dass sich der zwischen ihnen eingeschlossene Winkel verringert. Der Winkel zwischen den beiden Stangen wird also umso kleiner, je geringer der Abstand zwischen der Abstandswarnvorrichtung bzw. dem Fahrzeug und dem Hindernis ist. Die Größe des Winkels zwischen beiden Stangen stellt somit ein Maß für die momentane Distanz zwischen Fahrzeug und Hindernis dar. Je kleiner der zwischen den beiden Stangen eingeschlossene Winkel ist, desto geringer ist also der Abstand zwischen dem Fahrzeug und dem Hindernis. In ihrer Endposition können die beiden Stangen nahezu parallel zueinander ausgerichtet sein und in dieser Stellung auch das Hindernis berühren.In order to make it even easier for the driver to recognize the approach of his vehicle to the obstacle, a particularly advantageous embodiment provides that two bars in their rest positions are arranged essentially in a V-shape with respect to one another in the receiving part without the force being exerted by the vehicle and enclose an angle with one another, and that the receiving part has guides in which the rods can be moved in such a way that the angle enclosed between the rods is reduced when a force exerted by a part of the vehicle is applied. The A change in the angle of the rods relative to one another has the effect that a change in the distance between his vehicle and the obstacle is signaled to the driver. In this embodiment, the two rods move under the action of an external force exerted by the vehicle from their V-shaped rest position along their guides in the receiving part in such a way that the angle enclosed between them decreases. The angle between the two rods becomes smaller the smaller the distance between the distance warning device or the vehicle and the obstacle. The size of the angle between the two poles thus represents a measure of the instantaneous distance between the vehicle and the obstacle. The smaller the angle enclosed between the two poles, the smaller the distance between the vehicle and the obstacle. In their end position, the two rods can be aligned almost parallel to one another and can also touch the obstacle in this position.
Sind die Stangen der Abstandswarnvorrichtung verhältnismäßig starr ausgeführt, kann dies zur Folge haben, dass bei Erreichen der im wesentlichen hindernisseitigen Endposition der Stangen eine zusätzliche Krafteinwirkung dazu führt, dass Teile des Fahrzeuges und insbesondere die Abschnitte des Fahrzeugstoßfängers, die eine unmittelbare Berührung durch die Stangen erfahren, lokal einem verhältnismäßig hohen Druck ausgesetzt und daher plastisch und damit irreversibel verformt werden können. Darüber hinaus können auch die Stangen der Abstandswarnvorrichtung durch eine weitere Krafteinwirkung brechen und damit unbrauchbar werden.
Eine vorteilhafte Ausführungsform sieht daher vor, die Stangen der Abstandswarnvorrichtung selbst energieabsorbierend auszuführen. Das kann dadurch erreicht werden, dass die Stangen mindestens abschnittsweise aus biegeelastischem Material ausgeführt sind. Auf diese Weise wird ein Teil der Energie, die bei dem Kontakt des Fahrzeugs mit der Abstandswarnvorrichtung auf letztere übertragen wird, im biegeelastischen und damit reversibel verformbaren Material der Stangen absorbiert wird, während ein weiterer Teil in Bewegungsenergie der Stangen umgesetzt wird. Es hat sich als zweckmäßig erwiesen, zumindest einen biegeelastischen Stangenabschnitt in dem Bereich vorzusehen, der typischerweise vom Stoßfänger des Fahrzeugs berührt wird.If the rods of the distance warning device are designed to be relatively rigid, this can have the consequence that when the essentially obstacle-side end position of the rods is reached, additional force action leads to parts of the vehicle and in particular the sections of the vehicle bumper which are in direct contact with the rods , locally exposed to a relatively high pressure and can therefore be plastically and thus irreversibly deformed. In addition, the rods of the distance warning device can also break due to the application of additional force and thus become unusable.
An advantageous embodiment therefore provides for the rods of the distance warning device itself to be energy-absorbing. This can be achieved in that the rods are made of flexible material at least in sections. In this way, part of the energy generated by the contact of the Vehicle is transmitted to the latter with the distance warning device, is absorbed in the flexible and therefore reversibly deformable material of the rods, while another part is converted into kinetic energy of the rods. It has proven to be expedient to provide at least one flexible rod section in the area which is typically touched by the bumper of the vehicle.
Eine bevorzugte Ausführungsform der Abstandswarnvorrichtung sieht vor, dass die Stangen mehrere Teile umfassen, die lösbar miteinander verbunden sind. Die lösbare Verbindung der Teile kann beispielsweise als Steckverbindung realisiert sein. Diese Ausführungsform erleichtert den Transport der Abstandswarnvorrichtung und erlaubt es, defekte Teile mit einem relativ geringen Montageaufwand auszutauschen.A preferred embodiment of the distance warning device provides that the rods comprise several parts which are detachably connected to one another. The detachable connection of the parts can be implemented, for example, as a plug connection. This embodiment facilitates the transport of the distance warning device and allows defective parts to be replaced with a relatively small amount of assembly work.
Fahrzeuge werden in verschiedenen Größen hergestellt. Sie unterscheiden sich unter anderem durch die Fahrzeughöhe und damit sehr oft einhergehend auch durch die Sitzhöhe des Fahrers, die beispielsweise bei einem Kleinwagen im allgemeinen niedriger ist als bei einem Transporter oder Lastkraftwagen. Um die Abstandswarnvorrichtung optimal auf die Sitzhöhe und damit auf das Blickfeld des Fahrers anpassen zu können, sieht eine besonders zweckmäßige Ausführungsform vor, die Stangen der Abstandswarnvorrichtung ausziehbar auszubilden. Dadurch lässt sich auf einfache Weise die Länge der Stangen modifizieren und an unterschiedliche Fahrzeuggrößen bzw. Sitzhöhen des Fahrers anpassen. Zu diesem Zweck können die Stangen als Teleskopstangen ausgeführt sein. Derartige Teleskopstangen erlauben eine besonders einfache Handhabung der Höhenverstellung.Vehicles are made in different sizes. They differ, among other things, by the vehicle height and very often also by the driver's seat height, which is generally lower, for example, in a small car than in a van or truck. In order to be able to optimally adapt the distance warning device to the seat height and thus to the driver's field of vision, a particularly expedient embodiment provides for the rods of the distance warning device to be designed to be extendable. This allows the length of the bars to be modified in a simple manner and adapted to different vehicle sizes or seat heights of the driver. For this purpose, the rods can be designed as telescopic rods. Such telescopic rods allow particularly easy handling of the height adjustment.
Eine weitere Ausführungsform sieht vor, dass mindestens eine der Stangen lichtreflektierende Abschnitte aufweist. Dadurch wird es dem Fahrer insbesondere bei Dunkelheit erleichtert, die von Scheinwerfern des Fahrzeugs angestrahlten Stangen zu erkennen.A further embodiment provides that at least one of the rods has light-reflecting sections. This will make it Drivers, especially in the dark, are relieved to recognize the poles illuminated by the headlights of the vehicle.
Um die Wahrnehmbarkeit der Abstandswarnvorrichtung seitens des Fahrers bei der Annäherung des Fahrzeugs an das Hindernis zusätzlich zu verbessern, sieht eine weitere Ausführungsform vor, dass mindestens eine der Stangen der Abstandswarnvorrichtung zumindest eine Signaleinrichtung aufweist. Die Signaleinrichtung kann dabei vorzugsweise an einem oberen, dem Aufnahmeteil zugewandten Stangenabschnitt angebracht sein, um dem Fahrer die Erkennung zu erleichtern. Ferner kann die Farbgebung der Signaleinrichtung so gewählt sein, dass diese die Sichtbarkeit der Abstandswarnvorrichtung weiter verbessert.In order to additionally improve the perception of the distance warning device by the driver when the vehicle approaches the obstacle, a further embodiment provides that at least one of the rods of the distance warning device has at least one signal device. The signaling device can preferably be attached to an upper rod section facing the receiving part in order to make it easier for the driver to recognize it. Furthermore, the color of the signaling device can be selected so that it further improves the visibility of the distance warning device.
Um die Erkennung der Abstandswarnvorrichtung bei unzureichenden Lichtverhältnissen und insbesondere bei Dunkelheit zu erleichtern, sieht eine weitere Ausführungsform vor, dass lichtreflektierende Abschnitte auf der Signaleinrichtung angebracht sind. Diese sind vorzugsweise auf äußeren, dem Fahrer zugewandten Teilen der Signaleinrichtung angebracht. Derartige lichtreflektierende Abschnitte verbessern vor allem bei Dunkelheit die Wahrnehmung der Annäherung des Fahrzeugs an die Abstandswarnvorrichtung, weil das Licht der Fahrzeugscheinwerfer von diesen Abschnitten reflektiert wird.In order to facilitate the detection of the distance warning device in inadequate lighting conditions and in particular in the dark, a further embodiment provides that light-reflecting sections are attached to the signaling device. These are preferably attached to outer parts of the signaling device facing the driver. Such light-reflecting sections improve the perception of the approach of the vehicle to the distance warning device, especially in the dark, because the light of the vehicle headlights is reflected by these sections.
Eine weitere Ausführungsform sieht vor, dass die Signaleinrichtung Mittel zur Übertragung akustischer Signale aufweist. Überschreitet die Bewegung der Stangen der Abstandswarnvorrichtung eine bestimmte Schwelle, wird ein akustisches Signal erzeugt. Dabei kann beispielsweise die Tonhöhe und/oder die Signalwiederholungsfrequenz des akustischen Signals abhängig von der momentanen Lage der Stangen zueinander und/oder relativ zum Hindernis variiert werden.A further embodiment provides that the signal device has means for transmitting acoustic signals. If the movement of the rods of the distance warning device exceeds a certain threshold, an acoustic signal is generated. For example, the pitch and / or the signal repetition frequency of the acoustic signal can be dependent on the current position of the rods relative to each other and / or relative to the obstacle can be varied.
Für den Einsatz der Abstandswarnvorrichtung bei Dunkelheit oder an unzureichend beleuchteten Orten (zum Beispiel in Garagen, Tiefgaragen oder Parkhäusern) ist eine Ausführungsform der Abstandswarnvorrichtung besonders vorteilhaft, deren Signaleinrichtung Mittel zur Übertragung optischer Signale umfasst. Diese optischen Signale können lediglich zur Beleuchtung der Abstandswarnvorrichtung dienen. Sie können den Fahrer aber auch durch unterschiedliche Farbgebung und/oder Signalwiederholungsfrequenz in Abhängigkeit vom Abstand der Stangen vom Hindernis oder in Abhängigkeit von dem zwischen den Stangen eingeschlossenen Winkel zusätzlich vor einer Kollision des Fahrzeugs mit dem Hindernis warnen.For the use of the distance warning device in the dark or in insufficiently illuminated places (for example in garages, underground garages or parking garages), an embodiment of the distance warning device is particularly advantageous, the signaling device of which comprises means for transmitting optical signals. These optical signals can only serve to illuminate the distance warning device. However, you can also warn the driver of a collision of the vehicle with the obstacle by means of different colors and / or signal repetition frequencies depending on the distance of the bars from the obstacle or depending on the angle enclosed between the bars.
Um die Stangen der Abstandswarnvorrichtung nach dem Wegfall der auf sie einwirkenden Kraft wieder zuverlässig in ihre Ausgangsposition zu bringen, sieht eine weitere Ausführungsform vor, dass die Abstandswarnvorrichtung Rückstellmittel umfasst, die die Stangen in ihre Ausgangsposition zurückbewegen. Diese Rückstellmittel bewirken außerdem, dass den Stangen der Abstandswarnvorrichtung in ihrer Ruhelage eine zusätzliche Kraft vorgespannt ist. Dadurch wird ein zusätzlicher Widerstand erzeugt, der von der von außen durch das Fahrzeug einwirkenden Kraft zunächst überwunden werden muss, bevor sich die Stangen in Bewegung versetzen.In order to reliably bring the rods of the distance warning device back into their starting position after the force acting on them has ceased to exist, a further embodiment provides that the distance warning device comprises resetting means which move the rods back into their starting position. These restoring means also cause the rods of the distance warning device to be biased in their rest position by an additional force. This creates an additional resistance, which must be overcome by the force exerted by the vehicle from the outside before the rods start to move.
Vorzugsweise sind die Rückstellmittel im Aufnahmeteil der Abstandswarnvorrichtung angebracht.The resetting means are preferably attached in the receiving part of the distance warning device.
Eine besonders zweckmäßige Ausführungsform sieht vor, dass die Rückstellmittel mindestens eine Druckfeder umfassen. Die Verwendung mindestens einer Druckfeder, die beispielsweise aus Metall bestehen kann, stellt die rückstellende Wirkung auch bei häufigem Gebrauch der Abstandswarnvorrichtung sicher. Die mindestens eine Druckfeder kann innerhalb des Aufnahmeteils im Bereich der Führungen der Stangen oder unmittelbar an den Stangen angebracht sein.A particularly expedient embodiment provides that the restoring means comprise at least one compression spring. The use of at least one compression spring, which can be made of metal, for example, ensures the restoring effect even when the distance warning device is used frequently. The at least one compression spring can be attached within the receiving part in the region of the guides of the rods or directly on the rods.
Eine weitere vorteilhafte Ausführungsform sieht vor, dass die Rückstellmittel mindestens eine Blattfeder aufweisen. Blattfedern sind relativ einfach und kostengünstig herstellbar und behalten ihre rückstellende Wirkung auch bei häufiger Verwendung. Die mindestens eine Blattfeder kann innerhalb des Aufnahmeteils im Bereich der Führungen der Stangen oder unmittelbar an den Stangen angebracht sein.A further advantageous embodiment provides that the resetting means have at least one leaf spring. Leaf springs are relatively easy and inexpensive to manufacture and retain their restoring effect even with frequent use. The at least one leaf spring can be attached within the receiving part in the region of the guides of the rods or directly on the rods.
Die mindestens eine Blattfeder kann zumindest abschnittsweise aus Metall bestehen. Sie kann aber auch als Kunststoff- oder Fiberglas-Blattfeder ausgebildet sein. Die Kunststoff-Blattfeder kann dabei integraler Bestandteil des Aufnahmeteils sein, wobei das Aufnahmeteil und die Kunststoff-Blattfeder insbesondere durch ein herkömmliches Spritzgussverfahrens hergestellt werden können.The at least one leaf spring can consist of metal at least in sections. But it can also be designed as a plastic or fiberglass leaf spring. The plastic leaf spring can be an integral part of the receiving part, wherein the receiving part and the plastic leaf spring can be produced in particular by a conventional injection molding process.

Zunächst wird auf Fig. 1 Bezug genommen. Dort ist die erfindungsgemäße Abstandswarnvorrichtung 1, vor der sich ein Fahrzeug befindet, in einer Seitenansicht dargestellt. Die Abstandswarnvorrichtung umfasst zwei unabhängig von- und relativ zueinander sowie relativ zu einer Wand 7 bewegbare Stangen 2, 3 (vgl. hierzu auch die Fig. 2 und 3), die in einem Aufnahmeteil 4 angeordnet sind. In diesem Ausführungsbeispiel ist das Aufnahmeteil 4 der Abstandswarnvorrichtung 1 unmittelbar an der Wand 7 befestigt.First, reference is made to FIG. 1. There, the distance warning device 1 according to the invention, in front of which there is a vehicle, is shown in a side view. The distance warning device comprises two rods 2, 3 which can be moved independently of and relative to one another and relative to a wall 7 (cf. also FIGS. 2 and 3), which are arranged in a receiving part 4. In this embodiment, the receiving part 4 of the distance warning device 1 is attached directly to the wall 7.
Die Stangen 2, 3 der Abstandswarnvorrichtung können zumindest abschnittsweise aus Materialien aufgebaut sein, die bei einem Kontakt mit einem Fahrzeug 8 keinerlei Lackschäden an diesem hervorrufen. Zu diesem Zweck bietet es sich an, die Stangen vollständig, mindestens aber an ihren Oberflächen und insbesondere in den Bereichen, die mit Teilen des Fahrzeugs 8 in Berührung kommen können, aus glattem und lackschonendem Kunststoff auszuführen.The rods 2, 3 of the distance warning device can be constructed, at least in sections, from materials that do not cause any paint damage to the
Um einem Fahrer des Fahrzeugs 8 das Erkennen der Abstandswarnvorrichtung zu erleichtern, sind an den oberen Enden der Stangen 2, 3 Signaleinrichtungen vorgesehen, die in den Figuren 2 und 3 noch einmal explizit dargestellt sind. Die Signaleinrichtungen 5, 6 können lediglich aus einem mit einer Signalfarbe überzogenen Teil bestehen. Sie können darüber hinaus zumindest abschnittsweise lichtreflektierend sein und Mittel zur Übertragung optischer und/oder akustischer Signale aufweisen.In order to make it easier for a driver of
Diese Abbildung verdeutlicht, dass die Berührung der Stangen 2, 3 der Abstandswarnvorrichtung 1 mit einem Stoßfänger 10 eines Fahrzeugs 8 dazu führt, dass die im Aufnahmeteil 4 relativ zur Wand 7 schwenkbar angelenkten Stangen bei Wirkung einer äußeren Kraft, die durch den Pfeil 11 (Wirkungsrichtung der Kraft) angedeutet ist, gegen die Wand 7 verschwenkt werden können. Diese Schwenkbewegung kann vom Fahrer des Fahrzeugs 8 sehr einfach wahrgenommen werden.This illustration shows that the contact of the rods 2, 3 of the distance warning device 1 with a bumper 10 of a
Die Stangen 2, 3 der Abstandswarnvorrichtung 1 können dabei zumindest abschnittsweise an ihrer Oberfläche lichtreflektierende Materialen aufweisen, die dem Fahrer des Fahrzeugs 8 das Erkennen der Abstandswarnvorrichtung 1 bei einer Annäherung vor allem bei schlechten Sichtverhältnissen erheblich erleichtern. Die Stangen 2, 3 der Abstandswarnvorrichtung 1 sind im Aufnahmeteil 4 so gelagert, dass sie ausgehend von ihrer Ruhelage in ihrer Endposition im Wesentlichen parallel zur Wand 7 orientiert sind.The rods 2, 3 of the distance warning device 1 can have light-reflecting materials, at least in sections, on their surface, which considerably facilitate the detection of the distance warning device 1 when approaching, especially in poor visibility conditions. The rods 2, 3 of the distance warning device 1 are mounted in the receiving part 4 in such a way that, starting from their rest position, they are oriented in their end position essentially parallel to the wall 7.
Um nach dem Wegfall einer äußeren Kraft die Überführung der Stangen 2, 3 der Abstandswarnvorrichtung in ihre Ruhelagen zu ermöglichen, sind im Aufnahmeteil 4 Rückstellmittel vorgesehen (hier nicht explizit gezeigt), die Druckfedern und/oder Blattfedern aufweisen können.In order to enable the transfer of the rods 2, 3 of the distance warning device into their rest positions after the loss of an external force, 4 resetting means are provided in the receiving part (not explicitly shown here), which can have compression springs and / or leaf springs.
Fig. 2 zeigt eine Frontansicht der Abstandswarnvorrichtung 1 in einem unbelasteten Zustand, also in einem Zustand, in dem keine Kraft von einem Fahrzeug 8 auf die Abstandswarnvorrichtung 1 einwirkt. Es ist deutlich zu erkennen, dass die Stangen 2, 3, die an ihren oberen Enden jeweils eine Signaleinrichtung 5, 6 aufweisen in dieser Ruhelage im Aufnahmeteil 4 im Wesentlichen V-förmig zueinander angeordnet sind. Das Aufnahmeteil 4 der Abstandswarnvorrichtung 1 ist mit einer Mehrzahl von Befestigungsmitteln 9 an der in Fig. 1 gezeigten Wand 7 fixiert. Das Aufnahmeteil 4 kann auch hinreichend kippstabil ausgeführt sein, so dass eine Fixierung des Aufnahmeteils 4 an der Wand 7 nicht notwendig ist.FIG. 2 shows a front view of the distance warning device 1 in an unloaded state, that is to say in a state in which no force from a
Fig. 3 zeigt schließlich eine weitere Frontansicht der Abstandswarnvorrichtung, wobei in diesem Fall die Abstandswarnvorrichtung von einer äußeren Kraft beaufschlagt ist. Es ist deutlich zu erkennen, dass die beiden Stangen 2, 3 der Abstandswarnvorrichtung nun nahezu parallel zueinander ausgerichtet sind. Dies entspricht auch einer nahezu parallelen Stellung der Stangen 2, 3 der Abstandswarnvorrichtung 1 relativ zur Wand 7 in Fig.1. Damit die beiden Stangen 2, 3 bei einer äußeren Krafteinwirkung die Bewegung aus einer im Wesentlichen V-förmigen Ruheposition, wie sie in Fig. 2 dargestellt ist, in eine nahezu parallele Position gemäß Fig. 3 ausführen können, sind im Aufnahmeteil 4 entsprechende Führungen (nicht explizit dargestellt) vorgesehen.3 finally shows a further front view of the distance warning device, in which case the distance warning device is acted upon by an external force. It can be clearly seen that the two rods 2, 3 of the distance warning device are now aligned almost parallel to one another. This also corresponds to an almost parallel position of the rods 2, 3 of the distance warning device 1 relative to the wall 7 in FIG. 1. So that the two rods 2, 3 can perform the movement from an essentially V-shaped rest position, as shown in FIG. 2, to an almost parallel position according to FIG. not explicitly shown) provided.
Anhand dieses Ausführungsbeispiels wird deutlich, dass die Bewegungen der Stangen 2, 3, die unabhängig voneinander im Aufnahmeteil 4 angeordnet sind, dazu geeignet sind, dem Fahrer des Fahrzeugs 8 einen kritischen Abstand zum Hindernis zu signalisieren. Zum Einen ist hier die Schwenkbewegung der beiden Stangen 2, 3 relativ zur Wand 7, an der das Aufnahmeteil 4 angebracht ist, zu nennen. Zum Anderen ist dies die Bewegung der Stangen 2, 3 relativ zueinander von einer im Wesentlichen V-förmigen Ruhelage hin zu einer nahezu parallelen Orientierung der beiden Stangen zueinander. Die Kombination dieser Bewegungen der Stangen erleichtert es dem Fahrer erheblich, den Abstand zwischen seinem Fahrzeug 8 und der Wand 7 einzuschätzen und damit eine Kollision mit dem Hindernis 8 zu vermeiden.This exemplary embodiment makes it clear that the movements of the rods 2, 3, which are arranged independently of one another in the receiving part 4, are suitable for signaling the driver of the vehicle 8 a critical distance from the obstacle. On the one hand, the pivoting movement of the two rods 2, 3 relative to the wall 7 on which the receiving part 4 is attached is too call. On the other hand, this is the movement of the rods 2, 3 relative to one another from an essentially V-shaped rest position to an almost parallel orientation of the two rods to one another. The combination of these movements of the bars makes it considerably easier for the driver to estimate the distance between his
