Definitions

  • beacons On streets and squares, various types of beacons as well as information signs, prohibition signs, barriers and the like must be temporarily set up again and again.
  • beacons with or without additional traffic signs or lamps are placed in large numbers in close succession in order to create a route that is as visually complete as possible on the route sections deviating from the usual traffic route.
  • beacons are sometimes part of beacon stands, which are also called base plate stands and which have a base plate, a beacon tube and the beacon blade attached to the beacon tube. Sometimes these beacons are also designed as hollow beacon bodies, on the lower end of which a post part is attached or molded on.
  • the beacon tube or the post part is simply inserted into a recess in the central region of the base plate, which is matched to the shape and dimensions of the beacon tube or the post part.
  • an anti-rotation device is also created for the beacon sheet or the beacon body, by means of which the beacon is prevented from being underneath twisted by the influence of wind forces or by the air blasts of passing vehicles.
  • Such an anti-rotation device is very important during the day, so that the beacon surface, which is usually provided with a special color pattern, is oriented as perpendicular as possible to the route.
  • Such an anti-rotation device is even more important at night, because the beacon surface is generally included a reflective film is coated, which would cause undesirable light scattering when the beacon surface was inclined when the light of passing motor vehicles hit it, which at the same time would considerably reduce, if not eliminate, the directivity of the beacon.
  • the anti-rotation device is formed by a transverse pin arranged in the lower end region of the beacon tube and by two diametrically arranged guide grooves which are arranged diametrically on the base plate in the recess for the beacon tube.
  • beacon tubes and beacon blades thrown away can cause severe damage to other vehicles in the vicinity and can cause serious injuries, if not death, to road users hit by them.
  • the recess in the footplate is formed by a tubular steel section which is welded to the other steel parts of this footplate.
  • two radially continuous slots are cut in the upper part of the tube section, the development of which corresponds at least approximately to a Z rotated by 90 °. If a beacon tube with a cross pin is inserted into this holder, the both ends of the cross pin in the vertically aligned first portion of the slot. Then the tube is rotated through a certain angle, whereby the ends of the cross pin move along the horizontal portion of the slot in question.
  • the tube is then inserted again deeper into the holder, whereby the ends of the cross pin are lowered into the second vertical section of the slots.
  • the two Z-shaped slots form both an anti-rotation device and, to a certain extent, an anti-lift device.
  • this fails when the beacon tube with the beacon blade is raised when starting up such a beacon stand and the beacon tube is rotated in the direction in which the horizontal section of the Z-shaped slot extends due to an eccentric force attack on the beacon blade. Then the beacon tube can be completely pulled out of the holder and the beacon tube can be flung away due to the force that continues to act on the beacon blade.
  • this beacon stand also has the disadvantage that this double Z-shaped slot can only be produced in a very cumbersome manner and with a very high level of mechanical engineering by machining, namely by milling with a finger cutter. Therefore, this combined anti-rotation and anti-lift device fails due to the far too high manufacturing costs.
  • Another major disadvantage of this beacon stand is that during rough operation on road construction sites, the wall areas adjacent to the Z-shaped slot can be plastically deformed and then the beacon tube can either no longer be used or can only be partially inserted into the holder. Then the users of such beacon stands are faked to have an anti-lift device without it actually being present.
  • the invention specified in claims 1 and 3 is based on the object of providing a beacon stand with a base plate and a beacon tube or a post part, in which the beacon tube or the post part is more reliably secured both against twisting and against tearing out than in the known case Beacon stand.
  • the upper cross pin can be lifted out of the guide grooves.
  • the lower cross pin which is rotated by 90 ° in relation to the guide grooves, lies on the underside of the footplate the area around the recess and prevents further lifting or even pulling out of the post part from the footplate.
  • this beacon stand according to claim 2 it is achieved that after the lower transverse pin emerges from the guide grooves and after the post part has been rotated through 90 °, the projecting ends of the transverse pin firmly attach to the stop cams, so that the upper transverse pin then enters the guide grooves can be introduced. If all parts are properly coordinated, an additional securing of the beacon tube against shaking movements both about a horizontal axis and about the vertical longitudinal axis of the post part is avoided by elastic tensioning of the two stop pins against two mutually opposing pairs of side surfaces.
  • the only cross pin present is also also completely inserted through the guide grooves to the bottom of the footplate.
  • the protruding ends of the cross pin slide along the two contact surfaces in the form of annular sections, both of which act as axial ramp surfaces or cam surfaces and which pull the post part so far and so strongly into the footplate within the framework of the elastic deformability of all parts that the longitudinal stop abuts the post part firmly against the top of the footplate in the vicinity of the recess. Adequate anti-rotation is achieved by the considerable frictional force that occurs.
  • the fact that the protruding ends of the cross pin lie against the horizontally aligned surface sections at a point pivoted through 90 ° with respect to the guide grooves creates a play-free anti-lift device.
  • an additional securing of the post part is achieved in the rotational end position, because then the protruding ends of the cross pin rest at least in one direction on the contact surfaces of the stop cams.
  • the wedging of the lower end of the post part is achieved by the interaction of the largely cylindrical end section of the post part and the conical lateral surface sections on the additional wall parts. This also contributes to a play-free mounting of the beacon body on the footplate.
  • the effect of the anti-rotation and anti-lift device is further increased by the fact that the wall parts involved in this are made of a material of higher strength on the base plate, so that the good securing and the play-free mounting of the beacon body are also guaranteed is when the remaining part of the footplate is made of a cheaper plastic, in particular a recycled plastic, which itself has less strength.

Abstract

The road-sign stand (50) has a base plate (53) and a road-sign body (51) which can be joined to one another by plugging together. For this, the base plate (53) has a vertical, continuous recess (54). A cylindrical post part (52) matched to the latter is formed onto the road-sign body (51). This post part (52) is inserted into the recess (54) until the transition part (55) to the road-sign body (51) is seated on the edge of the recess (54). A cross-pin (56) is located on the post part (52) at least in the region of its lower end, at least one end section of said cross-pin projecting radially out of the post part (52). Two axial grooves for the passage of the end sections of the cross-pin (56) are formed in the periphery wall of the recess (54). Provided on the bottom side of the base plate (53) is a bearing face (58) on the end face for the cross-pin (55), which face is expediently designed as a peripheral sloping face. <IMAGE>

Description

Auf Straßen und Plätzen müssen immer wieder Baken der verschiedensten Art sowie Hinweisschilder, Verbotsschilder, Absperrschranken und dergleichen vorübergehend aufgestellt werden. Insbesondere an den Baustellen auf den Fernstraßen und Autobahnen werden Baken mit oder ohne zusätzliche Verkehrszeichen oder Lampen in größerer Anzahl dicht hintereinander aufgestellt, um an den vom üblichen Verkehrsweg abweichenden Streckenabschnitten eine visuell möglichst lückenlose Verkehrsführung zu schaffen.On streets and squares, various types of beacons as well as information signs, prohibition signs, barriers and the like must be temporarily set up again and again. In particular on the construction sites on the trunk roads and highways, beacons with or without additional traffic signs or lamps are placed in large numbers in close succession in order to create a route that is as visually complete as possible on the route sections deviating from the usual traffic route.

Diese Baken sind manchmal Teil von Bakenständern, die auch Fußplattenständer genannt werden und die eine Fußplatte, ein Bakenrohr sowie das am Bakenrohr befestigte Bakenblatt aufweisen. Manchmal sind diese Baken auch als hohle Bakenkörper ausgebildet, an deren unterem Ende ein Pfostenteil befestigt oder daran angeformt ist.These beacons are sometimes part of beacon stands, which are also called base plate stands and which have a base plate, a beacon tube and the beacon blade attached to the beacon tube. Sometimes these beacons are also designed as hollow beacon bodies, on the lower end of which a post part is attached or molded on.

Bei diesen Bakenständern wird das Bakenrohr oder der Pfostenteil einfach in eine Ausnehmung im mittleren Bereich der Fußplatte eingesteckt, die auf die Form und die Abmessungen des Bakenrohres bzw. des Pfostenteils abgestimmt ist. Soweit das Bakenrohr oder der Pfostenteil und die zugehörige Ausnehmung in der Fußplatte eine unrunde Querschnittsform haben, und zwar im allgemeinen eine quadratische oder rechteckige Querschnittsform, ist für das Bakenblatt oder den Bakenkörper zugleich eine Verdrehsicherung geschaffen, durch die verhindert wird, daß die Bake sich unter der Einwirkung von Windkräften oder durch die Luftstöße vorbeifahrender Fahrzeuge verdreht. Eine solche Verdrehsicherung ist schon bei Tage sehr wichtig, damit die in aller Regel mit einem besonderen Farbmuster versehene Bakenfläche möglichst rechtwinklig zur Streckenführung ausgerichtet ist. Bei Nacht ist eine solche Verdrehsicherung noch wichtiger, weil die Bakenfläche im allgemeinen mit einer reflektierenden Folie belegt ist, die bei einer Schrägstellung der Bakenfläche beim Auftreffen des Lichtes vorbeifahrender Kraftfahrzeuge unerwünschte Lichtstreuungen hervorrufen würde, die zugleich die Leitwirkung der Bake erheblich vermindern, wenn nicht gar beseitigen würde.With these beacon stands, the beacon tube or the post part is simply inserted into a recess in the central region of the base plate, which is matched to the shape and dimensions of the beacon tube or the post part. Insofar as the beacon tube or the post part and the associated recess in the base plate have a non-circular cross-sectional shape, generally a square or rectangular cross-sectional shape, an anti-rotation device is also created for the beacon sheet or the beacon body, by means of which the beacon is prevented from being underneath twisted by the influence of wind forces or by the air blasts of passing vehicles. Such an anti-rotation device is very important during the day, so that the beacon surface, which is usually provided with a special color pattern, is oriented as perpendicular as possible to the route. Such an anti-rotation device is even more important at night, because the beacon surface is generally included a reflective film is coated, which would cause undesirable light scattering when the beacon surface was inclined when the light of passing motor vehicles hit it, which at the same time would considerably reduce, if not eliminate, the directivity of the beacon.

Bei Bakenständern mit runden Bakenrohren ist eine gesonderte Verdrehsicherung zwischen dem Bakenrohr und der Fußplatte erforderlich. Bei einem bekannten Bakenständer dieser Art (DE-GM 84 14 270.7) wird die Verdrehsicherung durch einen im unteren Endbereich des Bakenrohres angeordneten Querstift und durch zwei diametral angeordnete lotrecht verlaufende Führungsnuten gebildet, die an der Fußplatte in der Ausnehmung für das Bakenrohr diametral angeordnet sind.In the case of beacon stands with round beacon tubes, a separate anti-rotation lock is required between the beacon tube and the base plate. In a known beacon stand of this type (DE-GM 84 14 270.7) the anti-rotation device is formed by a transverse pin arranged in the lower end region of the beacon tube and by two diametrically arranged guide grooves which are arranged diametrically on the base plate in the recess for the beacon tube.

Bei dieser einfachen Steckverbindung zwischen dem Bakenrohr und der Fußplatte und bei der ebenso einfachen Verdrehsicherung ist unter anderem von Nachteil, daß keinerlei Aushebesicherung vorhanden ist, die verhindert, daß das Bakenrohr mit dem Bakenblatt aus der Ausnehmung der Fußplatte herausgerissen wird, wenn der Bakenständer durch ein Fahrzeug angefahren wird. Solche weggeschleuderten Bakenrohre und Bakenblätter können bei anderen in der Nähe befindlichen Fahrzeugen schwere Beschädigungen hervorrufen und bei davon getroffenen Verkehrsteilnehmern schwere Verletzungen hervorrufen, wenn nicht gar deren Tod herbeiführen.With this simple plug connection between the beacon tube and the base plate and with the equally simple anti-rotation device, it is disadvantageous, inter alia, that there is no anti-lift device which prevents the beacon tube with the beacon blade from being torn out of the recess in the base plate when the beacon stand is inserted Vehicle is started. Such beacon tubes and beacon blades thrown away can cause severe damage to other vehicles in the vicinity and can cause serious injuries, if not death, to road users hit by them.

Bei einer der Ausführungsformen des bekannten Bakenständers wird die Ausnehmung in der Fußplatte durch einen Stahlrohrabschnitt gebildet, der mit den übrigen Stahlteilen dieser Fußplatte verschweißt ist. Anstelle der beiden lotrecht durchgehenden Führungsnuten sind im oberen Teil des Rohrabschnittes zwei radial durchgehende Schlitze eingeschnitten, deren Abwicklung zumindest näherungsweise einem um 90° gedrehten Z entspricht. Wenn in diese Halterung ein Bakenrohr mit einem Querstift eingesetzt wird, werden die beiden Enden des Querstiftes in dem lotrecht ausgerichteten ersten Abschnitt des Schlitzes abgesenkt. Dann wird das Rohr um einen gewissen Winkel verdreht, wodurch die Enden des Querstiftes sich an dem waagerecht verlaufenden Abschnitt des betreffenden Schlitzes entlangbewegen. Anschließend wird das Rohr nochmals tiefer in die Halterung eingesteckt, wodurch die Enden des Querstiftes in den zweiten lotrechten Abschnitt der Schlitze abgesenkt werden. In dieser Stellung bilden die beiden Z-förmigen Schlitze sowohl eine Verdrehsicherung, wie auch bis zu einem gewissen Grade eine Aushebesicherung. Diese versagt aber dann, wenn beim Anfahren eines solchen Bakenständers das Bakenrohr mit dem Bakenblatt angehoben wird und dabei infolge eines außermittigen Kraftangriffes am Bakenblatt das Bakenrohr gerade in der Richtung verdreht wird, in der der waagerechte Abschnitt des Z-förmigen Schlitzes verläuft. Dann kann aufgrund der am Bakenblatt meist weiterwirkenden Kraft das Bakenrohr vollständig aus der Halterung herausgezogen und das Bakenrohr weggeschleudert werden. Abgesehen von diesem Nachteil hat dieser Bakenständer auch noch den Nachteil, daß dieser zweifache Z-förmige Schlitz nur sehr umständlich und mit einem sehr hohen maschinentechnischen Aufwand durch spanabhebende Bearbeitung, nämlich durch Ausfräsen mit einem Fingerfräser, hergestellt werden kann. Daher scheitert diese kombinierte Verdreh- und Aushebesicherung schon an den viel zu hohen Fertigungskosten. Ein weiterer großer Nachteil dieses Bakenständers ist der, daß bei dem rauhen Betrieb auf den Straßenbaustellen die an den Z-förmigen Schlitz angrenzenden Wandbereiche plastisch verformt werden können und dann das Bakenrohr entweder gar nicht mehr oder nur noch zum Teil in die Halterung eingesetzt werden kann. Dann wird bei den Anwendern solcher Bakenständer das Vorhandensein einer Aushebesicherung vorgetäuscht, ohne daß sie in Wirklichkeit vorhanden ist. Außerdem können beim Transport der Fußplatten auf Baustellenfahrzeugen, beim Abladen der Fußplatten und beim Verteilen der Fußplatten entlang der Aufstellinie Schmutzteile in die Schlitze gelangen und sich darin festsetzen. Das ist besonders kritisch, wenn es sich dabei um Sand- und/oder Splittkörner handelt, die mit Bitumen benetzt sind, wodurch diese Körner in den Schlitzen festkleben und festbacken können. Auch dann lassen sich die Bakenrohre mit den Querstiften nicht mehr bis zur gesicherten Endstellung in die Fußplatten einsetzen. Dann ist bei diesen Bakenständern die Gefahr noch größer, daß bei einem Auffahrunfall das Bakenrohr mit dem Bakenblatt aus der Fußplatte herausgerissen wird, weil es in die Fußplatte nur teilweise eingesetzt ist.In one of the embodiments of the known beacon stand, the recess in the footplate is formed by a tubular steel section which is welded to the other steel parts of this footplate. Instead of the two perpendicular guide grooves, two radially continuous slots are cut in the upper part of the tube section, the development of which corresponds at least approximately to a Z rotated by 90 °. If a beacon tube with a cross pin is inserted into this holder, the both ends of the cross pin in the vertically aligned first portion of the slot. Then the tube is rotated through a certain angle, whereby the ends of the cross pin move along the horizontal portion of the slot in question. The tube is then inserted again deeper into the holder, whereby the ends of the cross pin are lowered into the second vertical section of the slots. In this position, the two Z-shaped slots form both an anti-rotation device and, to a certain extent, an anti-lift device. However, this fails when the beacon tube with the beacon blade is raised when starting up such a beacon stand and the beacon tube is rotated in the direction in which the horizontal section of the Z-shaped slot extends due to an eccentric force attack on the beacon blade. Then the beacon tube can be completely pulled out of the holder and the beacon tube can be flung away due to the force that continues to act on the beacon blade. Apart from this disadvantage, this beacon stand also has the disadvantage that this double Z-shaped slot can only be produced in a very cumbersome manner and with a very high level of mechanical engineering by machining, namely by milling with a finger cutter. Therefore, this combined anti-rotation and anti-lift device fails due to the far too high manufacturing costs. Another major disadvantage of this beacon stand is that during rough operation on road construction sites, the wall areas adjacent to the Z-shaped slot can be plastically deformed and then the beacon tube can either no longer be used or can only be partially inserted into the holder. Then the users of such beacon stands are faked to have an anti-lift device without it actually being present. In addition, when transporting the foot plates on construction site vehicles, when unloading the foot plates and when distributing the foot plates along the installation line, dirt parts can get into the slots and become fix in it. This is particularly critical if the grains of sand and / or grit are wetted with bitumen, which allows these grains to stick and bake in the slots. Even then, the beacon tubes with the cross pins can no longer be inserted into the base plates up to the secured end position. Then there is an even greater risk with these beacon stands that in the event of a rear-end collision, the beacon tube with the beacon blade is torn out of the footplate because it is only partially inserted into the footplate.

Der im Anspruch 1 und 3 angegebenen Erfindung liegt die Aufgabe zugrunde, einen Bakenständer mit einer Fußplatte und einem Bakenrohr oder einem Pfostenteil zu schaffen, bei dem das Bakenrohr oder der Pfostenteil sowohl gegen Verdrehen, wie auch gegen Herausreißen zuverlässiger gesichert ist, als bei dem bekannten Bakenständer.The invention specified in claims 1 and 3 is based on the object of providing a beacon stand with a base plate and a beacon tube or a post part, in which the beacon tube or the post part is more reliably secured both against twisting and against tearing out than in the known case Beacon stand.

Dadurch, daß bei der Ausführungsform nach Anspruch 1 zwei Querstifte vorhanden sind, die in einem gewissen axialen Abstand voneinander im Grundriß kreuzförmig angeordnet sind, wird erreicht, daß beim Einsetzen des Pfostenteils zunächst der untere Querstift in die Führungsnuten eingesetzt wird, bis der obere Querstift an der Oberseite der Fußplatte in der Umgebung der Ausnehmung aufsitzt. Da dabei der untere Querstift bereits aus der Ausnehmung ausgetreten ist, kann der Pfostenteil anschließend um 90° gedreht werden, bis der obere Querstift mit den beiden Führungsnuten fluchtet. Anschließend wird der Pfostenteil bis zum Aufsitzen seines Anschlagteils in die Ausnehmung so weit hineingesteckt, daß der obere Querstift vollständig in die Führungsnuten eintaucht. Der obere Führungsstift bildet dadurch eine Verdrehsicherung. Wenn das Bakenrohr bei einem Auffahrunfall angehoben werden sollte, kann zwar der obere Querstift aus den Führungsnuten herausgehoben werden. Der untere Querstift, der um 90° gegenüber den Führungsnuten verdreht ist, legt sich dabei jedoch an der Unterseite der Fußplatte in der Umgebung der Ausnehmung an und verhindert ein weiteres Anheben oder gar Herausziehen des Pfostenteils aus der Fußplatte.Characterized in that in the embodiment according to claim 1 two cross pins are present, which are arranged in a cross shape at a certain axial distance from each other in the plan, it is achieved that when inserting the post part, the lower cross pin is first inserted into the guide grooves until the upper cross pin on the top of the footplate sits in the vicinity of the recess. Since the lower cross pin has already emerged from the recess, the post part can then be turned through 90 ° until the upper cross pin is aligned with the two guide grooves. The post part is then inserted into the recess until its stop part is seated so that the upper transverse pin is completely immersed in the guide grooves. The upper guide pin thus forms an anti-twist device. If the beacon tube should be raised in the event of a rear-end collision, the upper cross pin can be lifted out of the guide grooves. However, the lower cross pin, which is rotated by 90 ° in relation to the guide grooves, lies on the underside of the footplate the area around the recess and prevents further lifting or even pulling out of the post part from the footplate.

Bei einer Ausgestaltung dieses Bakenständers nach Anspruch 2 wird erreicht, daß nach dem Austreten des unteren Querstiftes aus den Führungsnuten und nach dem Verdrehen des Pfostenteils um 90° die überstehenden Enden des Querstiftes sich an den Anschlagnocken fest anlegen, damit anschließend der obere Querstift in die Führungsnuten eingeführt werden kann. Bei richtiger Abstimmung aler Teile wird durch elastisches Verspannen der beiden Anschlagstifte gegen zwei einander entgegengesetzt wirkende Paare von Seitenflächen eine zusätzliche Sicherung des Bakenrohres gegen Rüttelbewegungen sowohl um eine horizontale Achse, wie auch um die lotrechte Längsachse des Pfostenteils vermieden.In one embodiment of this beacon stand according to claim 2 it is achieved that after the lower transverse pin emerges from the guide grooves and after the post part has been rotated through 90 °, the projecting ends of the transverse pin firmly attach to the stop cams, so that the upper transverse pin then enters the guide grooves can be introduced. If all parts are properly coordinated, an additional securing of the beacon tube against shaking movements both about a horizontal axis and about the vertical longitudinal axis of the post part is avoided by elastic tensioning of the two stop pins against two mutually opposing pairs of side surfaces.

Bei der Ausführungsform des Bakenständers nach Anspruch 3 wird der einzige vorhandene Querstift zunächst ebenfalls vollständig durch die Führungsnuten hindurch bis zur Unterseite der Fußplatte eingesteckt. Beim anschließenden Verdrehen des Pfostenteils gleiten die überstehenden Enden des Querstiftes an den beiden kreisringabschnittförmigen Anlageflächen entlang, die beide als axiale Rampenflächen oder Nockenflächen wirken und die den Pfostenteil im Rahmen der elastischen Verformbarkeit aller Teile so weit und so stark in die Fußplatte hineinziehen, daß der Längsanschlag am Pfostenteil fest an der Oberseite der Fußplatte in der Umgebung der Ausnehmung anliegt. Durch die dabei auftretende erhebliche Reibungskraft wird eine ausreichende Verdrehsicherung erreicht. Dadurch, daß die überstehenden Enden des Querstiftes an einer um 90° gegenüber den Führungsnuten verschwenkten Stelle an den waagerecht ausgerichteten Flächenabschnitten anliegen, wird eine spielfreie Aushebesicherung geschaffen.In the embodiment of the beacon stand according to claim 3, the only cross pin present is also also completely inserted through the guide grooves to the bottom of the footplate. When the post part is subsequently rotated, the protruding ends of the cross pin slide along the two contact surfaces in the form of annular sections, both of which act as axial ramp surfaces or cam surfaces and which pull the post part so far and so strongly into the footplate within the framework of the elastic deformability of all parts that the longitudinal stop abuts the post part firmly against the top of the footplate in the vicinity of the recess. Adequate anti-rotation is achieved by the considerable frictional force that occurs. The fact that the protruding ends of the cross pin lie against the horizontally aligned surface sections at a point pivoted through 90 ° with respect to the guide grooves creates a play-free anti-lift device.

Bei einer Ausgestaltung dieses Bakenständers nach Anspruch 4 wird eine zusätzliche Sicherung des Pfostenteils in der Drehendstellung erreicht, weil dann die überstehenden Enden des Querstiftes zumindest in der einen Richtung an den Anlageflächen der Anschlagnocken anliegen.In an embodiment of this beacon stand according to claim 4, an additional securing of the post part is achieved in the rotational end position, because then the protruding ends of the cross pin rest at least in one direction on the contact surfaces of the stop cams.

Bei einer Ausgestaltung dieses Bakenständers nach Anspruch 5 wird durch das Zusammenwirken des weitgehend zylindrischen Endabschnittes des Pfostenteils und der kegeligen Mantelflächenabschnitte an den zusätzlichen Wandteilen eine Verkeilung des unteren Endes des Pfostenteils erreicht. Das trägt zusätzlich zu einer spielfreien Halterung des Bakenkörpers an der Fußplatte bei.In an embodiment of this beacon stand according to claim 5, the wedging of the lower end of the post part is achieved by the interaction of the largely cylindrical end section of the post part and the conical lateral surface sections on the additional wall parts. This also contributes to a play-free mounting of the beacon body on the footplate.

Bei einer Ausgestaltung des Bakenständers nach Anspruch 6 wird die Wirkung der Verdrehsicherung und der Aushebesicherung dadurch nochmals gesteigert, daß die dabei mitwirkenden Wandteile an der Fußplatte aus einem Werkstoff höherer Festigkeit gefertigt sind, so daß die gute Sicherung und die spielfreie Halterung des Bakenkörpers auch dann gewährleistet ist, wenn der übrige Teil der Fußplatte aus einem billigeren Kunststoff, insbesondere aus einem Recycling-Kunststoff hergestellt wird, der selbst nur eine geringere Festigkeit hat.In an embodiment of the beacon stand according to claim 6, the effect of the anti-rotation and anti-lift device is further increased by the fact that the wall parts involved in this are made of a material of higher strength on the base plate, so that the good securing and the play-free mounting of the beacon body are also guaranteed is when the remaining part of the footplate is made of a cheaper plastic, in particular a recycled plastic, which itself has less strength.

The main components of the beacon stand 20 are a beacon body 21 with a post part 22 formed thereon and a base plate 23.

Der Bakenkörper 21 ist als Hohlkörper ausgebildet. Seine Querschnittsfläche hat entweder eine langgestreckte rechteckige Umrißlinie oder eine lanzettförmige Umrißlinie. Der Hohlkörper ist in herkömmlicher Kunststoff-Blastechnik gefertigt.The beacon body 21 is designed as a hollow body. Its cross-sectional area has either an elongated rectangular outline or a lancet-shaped outline. The hollow body is manufactured using conventional plastic blowing technology.

Am unteren Ende des eigentlichen Bakenkörpers 21 ist ein Übergangsteil 24 angeformt, das ebenfalls hohl ist. Es verbindet den prismatischen oder näherungsweise zylindrischen Bakenkörper 21 mit dem hohlzylindrischen Pfostenteil 22 (Fig. 5 und 6). Im Inneren des Pfostenteils 22 ist ein Metallrohr 25, und zwar im allgemeinen ein Stahlrohr, eingeformt. Dieses Metallrohr 25 erstreckt sich auch durch den hohlen Übergangsteil 24 hindurch in den Hohlraum des Bakenkörpers 21 hinein. Das Metallrohr 25 ist so lang bemessen, daß es bei lotrecht stehendem Bakenkörper 21 mindestens die übliche Höhe der Stoßstangen an Personenkraftwagen erreicht. Bei einem Auffahrunfall nimmt es die von der anstoßenden Stoßstange auf den Bakenkörper 21 übertragenen Kräfte auf und verhindert so, daß der Hohlkörper des Bakenkörpers 21 zerbrochen oder zerrissen wird und die dabei entstehenden Einzelteile weggeschleudert werden.At the lower end of the actual beacon body 21, a transition part 24 is formed, which is also hollow. It connects the prismatic or approximately cylindrical beacon body 21 to the hollow cylindrical post part 22 (FIGS. 5 and 6). A metal tube 25, generally a steel tube, is molded into the interior of the post portion 22. This metal tube 25 also extends through the hollow transition part 24 into the cavity of the beacon body 21. The metal tube 25 is dimensioned so long that it reaches at least the usual height of the bumpers on passenger cars when the beacon body 21 is vertical. In the event of a rear-end collision, it absorbs the forces transmitted from the abutting bumper to the beacon body 21 and thus prevents the hollow body of the beacon body 21 from being broken or torn and the resulting individual parts being thrown away.

Die Fußplatte 23 (Fig. 2 und 3) hat näherungsweise die Gestalt eines flachen Quaders mit einer Höhe von ca. 60 mm. Entlang der oberen Längs- und Querkanten ist die Fußplatte 23 abgeschrägt. Die Fußplatte 23 ist als Kunststoff-Formteil hergestellt, und zwar im allgemeinen aus Kunststoffabfällen, aus sogenanntem Recycling-Kunststoff.The base plate 23 (FIGS. 2 and 3) has approximately the shape of a flat cuboid with a height of approximately 60 mm. The foot plate 23 is beveled along the upper longitudinal and transverse edges. The base plate 23 is produced as a molded plastic part, generally from plastic waste, from so-called recycled plastic.

Die Fußplatte 23 weist zumindest näherungsweise in ihrer Mitte eine lotrecht verlaufende durchgehende erste Ausnehmung 26 auf, die einen kreisrunden Querschnitt für die Aufnahme des kreiszylindrischen Pfostenteils 22 hat. An der Innenwand der Ausnehmung 26 sind zwei Führungsnuten 27 eingeformt, die in der Querrichtung der Fußplatte 23 diametral angeordnet sind. Sie sind parallel zu den Mantellinien der Ausnehmung 26 ausgerichtet. Die Führungsnuten 27 sind in ihrer Längsrichtung, d.h. in lotrechter Richtung, durchgehend offen, so daß Schmutzablagerungen leicht nach unten herausgestoßen werden können.The base plate 23 has, at least approximately in its center, a perpendicular, continuous first recess 26, which has a circular cross section for receiving the circular cylindrical post part 22. On the inner wall of the recess 26, two guide grooves 27 are formed, which are arranged diametrically in the transverse direction of the foot plate 23. They are aligned parallel to the surface lines of the recess 26. The guide grooves 27 are continuously open in their longitudinal direction, ie in the vertical direction, so that dirt deposits can be pushed out downwards easily.

An der Unterseite 28 der Fußplatte 23 ist in der Umgebung der ersten Ausnehmung 26 eine zweite Ausnehmung 29 eingeformt. Sie hat die Gestalt eines flachen Kreiszylinders. Die lichte Weite der zweiten Ausnehmung 29 ist größer als der lichte Abstand des Nutgrundes der beiden Führungsnuten 27, so daß die beiden Führungsnuten in der zweiten Ausnehmung 29 frei münden.A second recess 29 is formed on the underside 28 of the base plate 23 in the vicinity of the first recess 26. It has the shape of a flat circular cylinder. The inside width of the second recess 29 is greater than the inside distance of the groove base of the two guide grooves 27, so that the two guide grooves open into the second recess 29.

In Fig. 2 ist an der Unterseite 28 der Fußplatte 23 eine dritte Ausnehmung 31 gestrichelt angedeutet. Diese dritte Ausnehmung 31 hat eine Grundrißform, die annähernd gleich derjenigen eines ringförmig in sich geschlossenen Führungswulstes 32 ist, der eine quadratische Umrißlinie hat. Dieser Führungswulst 32 erhebt sich um ein gewisses Maß über die Oberseite 33 der Fußplatte 23. Dieser Führungswulst 32 bildet zusammen mit der dritten Ausnehmung 31 eine Stapelhilfe für das Aufstapeln der Fußplatten 23. Da diese Stapelhilfe für die Halterung zwischen Fußplatte 23 und Pfostenteil 21 keine Bedeutung hat, bleibt sie im folgenden außer Betracht.In Fig. 2, a third recess 31 is indicated by dashed lines on the underside 28 of the base plate 23. This third recess 31 has a plan shape which is approximately the same as that of a ring-shaped, self-contained guide bead 32 which has a square outline. This guide bead 32 rises to a certain extent above the upper side 33 of the foot plate 23. This guide bead 32 forms, together with the third recess 31, a stacking aid for stacking the foot plates 23. Since this stacking aid is of no importance for the mounting between the foot plate 23 and the post part 21 has been disregarded in the following.

Wie aus Fig. 5 und 6 zu ersehen ist, sind am Pfostenteil 22 zwei Querstifte 34 und 35 vorhanden. Dafür werden Spannstifte aus Federstahlband verwendet. Sie sind in je eine auf ihren Durchmesser abgestimmte Querbohrung des Pfostenteils 22 stramm eingesetzt. Diese Querbohrungen sind diametral zum Pfostenteil 22 ausgerichtet. Sie durchsetzen dabei auch das Metallrohr 25 (Fig. 5).As can be seen from FIGS. 5 and 6, two cross pins 34 and 35 are present on the post part 22. Spring pins made of spring steel tape are used for this. They are tightly inserted in a transverse bore of the post part 22 which is matched to their diameter. These cross holes are aligned diametrically to the post part 22. They also penetrate the metal tube 25 (Fig. 5).

Wie aus Fig. 7 zu ersehen ist, sind in einer Axialprojektion oder in einer Grundrißprojektion des Pfostenteils 22 die beiden Querstifte 34 und 35 in einem Winkel von zumindest annähernd 90° gegeneinander verschwenkt angeordnet.As can be seen from FIG. 7, in an axial projection or in a plan projection of the post part 22, the two transverse pins 34 and 35 are arranged pivoted relative to one another at an angle of at least approximately 90 °.

Der lichte Abstand zwischen den einander zugekehrten und parallel zueinander ausgerichteten Tangentialebenen der beiden Querstifte 34 und 35 ist größer als der Abstand zwischen der Oberseite 33 der Fußplatte 23 und der Stirnseite 36 der zweiten Ausnehmung 29 (Fig. 8).The clear distance between the mutually facing and parallel tangential planes of the two transverse pins 34 and 35 is greater than the distance between the top 33 of the foot plate 23 and the end face 36 of the second recess 29 (FIG. 8).

Wie aus Fig. 8 und 9 ebenfalls zu ersehen ist, ist die radiale lichte Weite der zweiten Ausnehmung 29 größer als die radiale Erstreckung des unteren oder zweiten Querstiftes 35. Die lichte Höhe der zweiten Ausnehmung 29 ist größer als die Höhe desjenigen Längenabschnittes 37 des Pfostenteils 22, der aus der ersten Ausnehmung 26 heraus und nach unten in die zweite Ausnehmung 29 hineinragt, wenn der Pfostenteil 22 in die Fußplatte 23 vollständig eingesetzt ist (Fig. 9). Dadurch wird vermieden, daß der Pfostenteil 22 nach unten über die Unterseite 28 der Fußplatte 23 hervorsteht. Sofern die Fußplatte 23 an ihrer Unterseite mit Füßen, Fußleisten oder Noppen versehen ist, bezieht sich die Angabe 'Unterseite' der Fußplatte 23 auf die Aufstandsfläche dieser zusätzlichen Formteile.As can also be seen from FIGS. 8 and 9, the radial clear width of the second recess 29 is greater than the radial extent of the lower or second transverse pin 35. The clear height of the second recess 29 is greater than the height of that length section 37 of the post part 22, which protrudes out of the first recess 26 and down into the second recess 29 when the post part 22 is fully inserted into the foot plate 23 (FIG. 9). This avoids that the post part 22 protrudes downward over the underside 28 of the foot plate 23. If the base plate 23 is provided with feet, skirting boards or knobs on its underside, the indication 'underside' of the base plate 23 relates to the contact area of these additional molded parts.

Wie vor allem aus Fig. 9 ersichtlich ist, stellt der Übergangsteil 24 des Bakenkörpers 21 einen Längsanschlag für den Pfostenteil 22 dar. Das gilt streng genommen für die in Fig. 9 gestrichelt angedeutete Querschnittsebene 38, an der der Übergangsteil 24 mit seiner Mischform aus Pyramide und Kegelstumpf in die rein kreiszylindrische Form des Pfostenteils 22 übergeht. In Höhe dieser Querschnittsebene 38 legt der Übergangsteil 24 sich als Anschlagteil an der oberen Innenkante 39 der ersten Ausnehmung 26 an.As can be seen above all from FIG. 9, the transition part 24 of the beacon body 21 represents a longitudinal stop for the post part 22. Strictly speaking, this applies to the cross-sectional plane 38 indicated by dashed lines in FIG. 9, on which the transition part 24 with its mixed form of pyramid and the truncated cone merges into the purely cylindrical shape of the post part 22. At the level of this cross-sectional plane 38, the transition part 24 rests as a stop part on the upper inner edge 39 of the first recess 26.

Wie aus der Abfolge von Fig. 8 und 9 erkennbar ist, wird der Bakenkörper 21 mit der Fußplatte 23 in der Weise vereinigt, daß der Pfostenteil 22 so in die erste Ausnehmung eingesteckt wird, daß der an seinem unteren Ende befindliche zweite Querstift 35 mit den beiden Führungsnuten 27 fluchtet. Der Pfostenteil 22 wird zunächst so weit in die erste Ausnehmung 26 hineingesteckt, bis sein erster Anschlagstift 34 an der Oberseite 33 der Fußplatte 23 in der Umgebung der Ausnehmung 26 aufliegt. In dieser Montagestellung befindet sich der zweite Querstift 35 bereits unterhalb der ersten Ausnehmung 26 und ihrer Führungsnuten 27. Der Bakenkörper 21 wird dann um 90° gedreht, bis sein erster Querstift 34 mit den beiden Führungsnuten 27 fluchtet. Dann wird der Pfostenteil 22 nochmals ein Stück weiter in die erste Ausnehmung 26 eingesteckt, bis der als Längsanschlag dienende Übergangsteil 24 an der Innenkante 39 der ersten Ausnehmung 26 sich anlegt und er erste Querstift 34 sich um ein gewisses Maß unterhalb der Oberseite 33 der Fußplatte befindet. Der zweite Querstift 35 ragt dabei frei in die zweite Ausnehmung 29 hinein. In der Grundrißprojektion ist er um 90° gegenüber derjenigen Diametralebene geschwenkt, in der die beiden Führungsnuten 27 gelegen sind.As can be seen from the sequence of FIGS. 8 and 9, the beacon body 21 is combined with the base plate 23 in such a way that the post part 22 is inserted into the first recess in such a way that the second transverse pin 35 located at its lower end with the two guide grooves 27 are aligned. The post portion 22 is initially so far into the inserted the first recess 26 until its first stop pin 34 rests on the top 33 of the foot plate 23 in the vicinity of the recess 26. In this assembly position, the second cross pin 35 is already below the first recess 26 and its guide grooves 27. The beacon body 21 is then rotated by 90 ° until its first cross pin 34 is aligned with the two guide grooves 27. Then the post part 22 is inserted a little further into the first recess 26 until the transition part 24 serving as a longitudinal stop lies against the inner edge 39 of the first recess 26 and the first transverse pin 34 is located to a certain extent below the upper side 33 of the footplate . The second cross pin 35 projects freely into the second recess 29. In the plan projection, it is pivoted through 90 ° with respect to the diametral plane in which the two guide grooves 27 are located.

Wenn der Bakenständer 20 angefahren wird und dabei durch äußere Kräfte sein Bakenkörper 21 angehoben wird, tritt allenfalls der erste Querstift 34 aus den Führungsnuten 27 der ersten Ausnehmung 26 heraus. Der zweite Querstift 35 legt sich dabei an die Stirnseite 36 der zweiten Ausnehmung 29 an und hält dadurch den Bakenkörper 21 an der Fußplatte 23 fest.When the beacon stand 20 is approached and its beacon body 21 is raised by external forces, the first transverse pin 34 at most emerges from the guide grooves 27 of the first recess 26. The second cross pin 35 lies against the end face 36 of the second recess 29 and thereby holds the beacon body 21 firmly on the foot plate 23.

Aus Fig. 10 und 11 ist eine Abwandlung des Bakenständers 20 zu ersehen.A modification of the beacon stand 20 can be seen from FIGS. 10 and 11.

Die Fußplatte 41 mit ihrer kreiszylindrischen ersten Ausnehmung 42 und den beiden Führungsnuten 43 weist an ihrer Unterseite zwei Anschlagnocken 44 auf. Diese sind als axiale Fortsätze des die Ausnehmung 42 umgebenden Wandteils 45 und auch als zusätzliche Wandteile der Fußplatte 41 zu verstehen. Die eine nahezu radial ausgerichtete Seitenwand 46 der Anschlagnocken 44 fluchtet mit der einen Seitenwand 47 der Führungsnuten 43. Die zweite ebenfalls annähernd radial ausgerichtete Seitenwand 48 der Anschlagnocken 44 bildet eine in Umfangsrichtung wirkende Anlagefläche für den zweiten Querstift 35 wenn dieser aus der mit den Führungsnuten 43 fluchtenden Drehstellung heraus um 90° in seine Endstellung verschwenkt wird (Fig. 10). Wenn danach der Pfostenteil 22 tiefer in die Fußplatte 41 hineingesteckt wird, so daß auch sein oberer erster Querstift 34 in die Führungsnuten 43 eintaucht, dann legt dieser sich an der Seitenwand 47 der Führungsnuten 43 an und gleitet an ihr entlang. In Fig. 10 ist nur der besseren Übersichtlichkeit halber zwischen der mit der Seitenwand 46 fluchtenden Seitenwand 47 der Führungsnut 43 und dem ersten Querstift 34 ein kleines Spiel dargestellt, das in Wirklichkeit nicht vorhanden ist.The base plate 41 with its circular cylindrical first recess 42 and the two guide grooves 43 has two stop cams 44 on its underside. These are to be seen as axial extensions of the wall part 45 surrounding the recess 42 and also as additional wall parts of the base plate 41 understand. The almost radially oriented side wall 46 of the stop cams 44 is aligned with the one side wall 47 of the guide grooves 43. The second, also approximately radially oriented side wall 48 of the stop cams 44 forms a circumferentially acting contact surface for the second cross pin 35 when it comes out of the one with the guide grooves 43 aligned rotating position is pivoted 90 ° into its end position (Fig. 10). If the post part 22 is then inserted deeper into the base plate 41 so that its upper first transverse pin 34 also dips into the guide grooves 43, then it lies against the side wall 47 of the guide grooves 43 and slides along it. In FIG. 10, only for the sake of clarity, a small play is shown between the side wall 47 of the guide groove 43 aligned with the side wall 46 and the first transverse pin 34, which is in fact not present.

Im folgenden wird anhand Fig. 12 bis 16 eine zweite Ausführungsform des Bakenständers erläutert. Soweit dabei einzelne Merkmale nicht mehr gesondert erwähnt werden, ist davon auszugehen, daß sie gleich oder zumindest ähnlich den entsprechenden Merkmalen des Bakenständers 20 ausgebildet und/oder angeordnet sind.A second embodiment of the beacon stand is explained below with reference to FIGS. 12 to 16. Insofar as individual features are no longer mentioned separately, it can be assumed that they are designed and / or arranged the same or at least similar to the corresponding features of the beacon stand 20.

Der nur ausschnittweise dargestellte Bakenständer 50 weist, ebenso wie der Bakenständer 20 einen Bakenkörper 51 mit dem Pfostenteil 52 sowie eine Fußplatte 53 auf.The beacon stand 50, which is only shown in sections, has, like the beacon stand 20, a beacon body 51 with the post part 52 and a foot plate 53.

Die Fußplatte 53 weist wiederum eine kreiszylindrische erste Ausnehmung 54 für die Aufnahme des Pfostenteils 52 auf. Der Übergangsteil 55 zwischen dem eigentlichen Bakenkörper 51 und seinem Pfostenteil 52 wirkt auch hier als Längsanschlag für den Bakenkörper 51, der in der Betriebsstellung des Bakenkörpers 51 dessen axiale Relativstellung gegenüber der Fußplatte 53 festlegt.The base plate 53 in turn has a circular cylindrical first recess 54 for receiving the post part 52. The transition part 55 between the actual beacon body 51 and its post part 52 also acts here as a longitudinal stop for the beacon body 51, which, in the operating position of the beacon body 51, defines its axial relative position with respect to the foot plate 53.

Am Pfostenteil 52 ist nur ein Querstift 56 vorhanden, der im Bereich des unteren Endes des Pfostenteils 52 angeordnet ist. Er hat von dem Übergangsteil 55 als Längsanschlag einen lichten Abstand, der gleich ist dem Außenabstand 'a' zwischen der Oberseite 57 der Fußplatte 53 und der Stirnseite 58 einer zweiten Ausnehmung 59, die an der Unterseite der Fußplatte 53 in der Umgebung der ersten Ausnehmung 54 als eine Art Erweiterung dieser Ausnehmung vorhanden ist.There is only one cross pin 56 on the post part 52, which is arranged in the region of the lower end of the post part 52. It has a clear distance from the transition part 55 as a longitudinal stop, which is equal to the outer distance 'a' between the top 57 of the foot plate 53 and the end face 58 of a second recess 59, which is on the underside of the foot plate 53 in the vicinity of the first recess 54 as a kind of extension of this recess.

Diese zweite Ausnehmung (59) ist zumindest näherungsweise auf zwei diametral gelegene Quadranten der Umgebung der ersten Ausnehmung 54 beschränkt. Die zweite Ausnehmung 59 weist in diesen beiden Quadranten an ihrer Stirnseite je eine Anlagefläche 61 für eines der überstehenden Enden des Querstiftes 56 auf. Diese beiden Anlageflächen haben die Grundrißform eines Kreisringabschnittes, dessen innerer Halbmesser gleich dem Halbmesser der ersten Ausnehmung 54 ist und dessen Außenhalbmesser etwas größer als das Halbmessermaß eines der freien Enden des Querstiftes 56 ist. Die Umfangserstreckung der beiden Anlageflächen 61 entspricht einem Schwenkwinkel von zumindest annähernd 90°, wenn man von der in der Schwenkrichtung des Querstiftes 56 gelegenen Seitenwand 62 der zugehörigen Führungsnut 63 ausgeht.This second recess (59) is at least approximately limited to two diametrically located quadrants in the vicinity of the first recess 54. The second recess 59 has in each of these two quadrants on its end face a contact surface 61 for one of the projecting ends of the cross pin 56. These two contact surfaces have the outline shape of a circular ring section, the inner radius of which is equal to the radius of the first recess 54 and the outer radius of which is somewhat larger than the radius of one of the free ends of the cross pin 56. The circumferential extent of the two contact surfaces 61 corresponds to a swivel angle of at least approximately 90 ° if one starts from the side wall 62 of the associated guide groove 63 which is in the swivel direction of the cross pin 56.

Die beiden Anlageflächen 61 sind nicht eben. Sie weisen zwei Flächenabschnitte mit unterschiedlichem Verlauf auf. Der erste Flächenabschnitt 64, der bei der Seitenwand 62 der Führungsnut 63 beginnt (Fig. 14 und 16), ist als Rampenfläche ausgebildet. Sie hat von der Oberseite 57 der Fußplatte 53 in der Umgebung der ersten Ausnehmung 54 einen lichten Abstand, der am Anfang des Flächenabschnittes 64 kleiner als der lichte Abstand 'a' zwischen dem Querstift 56 und dem Längsanschlag 55 ist. Im Verlauf des ersten Flächenabschnittes 64 steigt der Abstand von der Oberseite 57 stetig bis auf einen Wert an, der im Rahmen der elastischen Verformbarkeit der Fußplatte 53 und des Pfostenteils 52 einschließlich des Übergangsteils 55 größer als der lichte Abstand 'a' ist. Der an den ersten Flächenabschnitt 64 anschließende zweite Flächenabschnitt 65 hat einen Außenabstand von der Oberseite 57 der Fußplatte 53, der entweder gleich dem Abstandswert am Ende des ersten Flächenabschnittes 64 ist oder der vom Ende des ersten Flächenabschnittes 64 an geringfügig abnimmt.The two contact surfaces 61 are not flat. They have two surface sections with different courses. The first surface section 64, which begins at the side wall 62 of the guide groove 63 (FIGS. 14 and 16), is designed as a ramp surface. It has a clear distance from the upper side 57 of the foot plate 53 in the vicinity of the first recess 54, which is smaller at the beginning of the surface section 64 than the clear distance 'a' between the transverse pin 56 and the longitudinal stop 55. In the course of the first surface section 64, the distance from the upper side 57 increases steadily to a value which is greater than the clear one within the framework of the elastic deformability of the foot plate 53 and the post part 52 including the transition part 55 Distance 'a' is. The second surface section 65 adjoining the first surface section 64 has an external distance from the upper side 57 of the foot plate 53 which is either equal to the distance value at the end of the first surface section 64 or which decreases slightly from the end of the first surface section 64.

Beim Einsetzen des Bakenkörpers 51 in die Fußplatte 53 wird der Pfostenteil 52 in seiner Schwenkstellung so ausgerichtet, daß der Querstift 56 mit den beiden Führungsnuten 63 fluchtet. Der Pfostenteil 52 wird in die Ausnehmung 54 so weit eingesteckt, bis der Übergangsteil 55 als Längsanschlag an der Innenkante der ersten Ausnehmung 54 sich anlegt. Danach wird der Bakenkörper 51 in der Drehrichtung gedreht, in der sich an die Führungsnuten 63 die beiden Anlageflächen 61 anschließen. Nach einem gewissen Schwenkweg trifft der Querstift 56 auf die Rampenfläche des ersten Flächenabschnittes 64. Unter Anwendung eines gewissen Drehmomentes wird der Bakenkörper 51 weitergedreht, wodurch der Querstift 56 auf dem ersten Flächenabschnitt 64 entlanggleitet, bis er den zweiten Flächenabschnitt 65 erreicht hat. Dabei werden alle zusammenwirkenden Teile in axialer Richtung, bezogen auf den Pfostenteil 52, elastisch verspannt. Auf dem ebenen oder allenfalls leicht abschüssigen zweiten Flächenabschnitt 65 bleibt der Querstift 56 infolge der dort wirkenden Reibungskraft von alleine stehen, was bei einem abschüssigen Verlauf des Flächenabschnittes 65 noch unterstützt wird.When inserting the beacon body 51 into the foot plate 53, the post part 52 is aligned in its pivoted position so that the cross pin 56 is aligned with the two guide grooves 63. The post part 52 is inserted into the recess 54 until the transition part 55 abuts as a longitudinal stop on the inner edge of the first recess 54. The beacon body 51 is then rotated in the direction of rotation in which the two contact surfaces 61 adjoin the guide grooves 63. After a certain swivel path, the cross pin 56 hits the ramp surface of the first surface section 64. Using a certain torque, the beacon body 51 is rotated further, whereby the cross pin 56 slides along the first surface section 64 until it has reached the second surface section 65. All interacting parts are elastically clamped in the axial direction, based on the post part 52. On the flat or possibly slightly sloping second surface section 65, the transverse pin 56 stops by itself due to the frictional force acting there, which is further supported in the case of a sloping course of the surface section 65.

Mit den anderen beiden Quadranten, die zwischen den beiden Quadranten mit den Anlageflächen 61 gelegenen sind, sind wiederum zwei Anschlagnocken 66 vorhanden, die ähnlich den Anschlagnocken 42 (Fig. 10) ausgebildet sind. Ihre den Anlageflächen 61 zugekehrte Seitenfläche 57 wirkt wiederum als Schwenkanschlag für den Querstift 56, wenn dieser in seine Endstellung beim zweiten Flächenabschnitt 65 geschwenkt wird (Fig. 15).With the other two quadrants, which are located between the two quadrants with the contact surfaces 61, there are in turn two stop cams 66 which are designed similarly to the stop cams 42 (FIG. 10). Its side surface 57 facing the contact surfaces 61 in turn acts as a pivot stop for the cross pin 56 when it is pivoted into its end position at the second surface section 65 (FIG. 15).

Abweichend von der kreiszylindrischen Innenfläche der Anschlagnocken 42 ist bei den Anschlagnocken 66 die an die erste Ausnehmung 54 stufenlos anschließende Innenfläche 68 als Abschnitt einer Kegelstumpf-Mantelfläche ausgebildet, die einen sehr kleinen Kegelwinkel hat. Diese Kegelstumpf-Mantelflächen verjüngen sich zu ihrem freien Rand hin, der der Unterseite der Fußplatte zugekehrt ist. Durch diese Verjüngung der Innenflächen 68, die wiederum im Rahmen der elastischen Verformbarkeit des Werkstoffes und der Form der Anschlagnocken 66 liegt, wird bewirkt, daß der zumindest annähernd kreiszylindrische Endabschnitt 69 des Pfostenteils 52 der unterhalb des Querstiftes 56 gelegen ist (Fig. 12), sich unter elastischer Verformung der Anschlagnocken 66 an deren Innenfläche 68 anlegt, wenn der Pfostenteil 52 in seine axiale Endstellung gebracht wird und er darin unter Ausnutzung der Rampenwirkung des ersten Flächenabschnittes 64 zusätzlich zwischen die Anschlagnocken 66 hineingedrückt wird.In a departure from the circular cylindrical inner surface of the stop cams 42, in the stop cams 66 the inner surface 68, which is continuously connected to the first recess 54, is designed as a section of a truncated cone surface which has a very small cone angle. These truncated cone surfaces taper towards their free edge, which faces the underside of the base plate. This tapering of the inner surfaces 68, which in turn is within the scope of the elastic deformability of the material and the shape of the stop cams 66, has the effect that the at least approximately circular-cylindrical end section 69 of the post part 52 is located below the transverse pin 56 (FIG. 12), rests with elastic deformation of the stop cams 66 on the inner surface 68 thereof when the post part 52 is brought into its axial end position and it is additionally pressed therein between the stop cams 66 using the ramp effect of the first surface section 64.

In Fig. 15 ist ein Rastelement 71 in Form des Linsenkopfes einer Linsenkopfschraube dargestellt, die am Übergang zwischen dem ansteigenden ersten Flächenabschnitt 64 und dem ebenen oder absteigenden zweiten Flächenabschnitt 65 angeordnet ist. Ein solches Rastelement 71 ist dann zweckmäßig, wenn die Abriebfestigkeit des Werkstoffes der Fußplatte 53 zumindest im Bereich der beiden Flächenabschnitte 64 und 65 nicht sehr groß ist und dadurch der Fall eintreten könnte, daß gerade im Übergangsbereich der beiden Flächenabschnitte 64 und 65 der Werkstoff durch den Querstift 56 beim wiederholten Einsatz abgeschabt wird.15 shows a locking element 71 in the form of the lens head of a lens head screw which is arranged at the transition between the rising first surface section 64 and the flat or descending second surface section 65. Such a locking element 71 is expedient if the abrasion resistance of the material of the foot plate 53 is not very great, at least in the area of the two surface sections 64 and 65, and this could result in the fact that in the transition area of the two surface sections 64 and 65, the material through the Cross pin 56 is scraped off during repeated use.

Noch viel zweckmäßiger ist eine Ausgestaltung des Bakenständers 54, die in den Zeichnungen nicht dargestellt ist und die darin besteht, daß die Wandteile der ersten Ausnehmung 54, der zweiten Ausnehmung 59 mindestens im Bereich der beiden Anlageflächen 61, besser im gesamtenEven more expedient is an embodiment of the beacon stand 54, which is not shown in the drawings and which consists in that the wall parts of the first recess 54, the second recess 59 at least in the region of the two contact surfaces 61, better overall

Bereich der zweiten Ausnehmung 59 einschließlich der Innenflächen 68 der Anschlagnocken 66, als verhältnismäßig dünne Wandteile eines zusammenhängenden Kunststoff-Formteils ausgebildet sind, das aus einem Kunststoff gefertigt wird, dessen Formfestigkeit und Abriebfestigkeit erheblich größer ist als der Werkstoff des übrigen Teils der Fußplatte 53. Dieses Kunststoff-Formteil wird bei der Fertigung der Fußplatte in diese mit eingeformt oder, umgekehrt ausgedrückt, der übrige Teil der Fußplatte 53 an diesem Kunststoff-Formteil angeformt. Zur Verbesserung der Verankerung des Kunststoff-Formteils in der Fußplatte 53 können auf der Außenseite des Kunststoff-Formteils zusätzliche Verankerungselemente angeformt sein.Area of the second recess 59, including the inner surfaces 68 of the stop cams 66, are designed as relatively thin wall parts of a coherent plastic molded part, which is manufactured from a plastic whose dimensional stability and abrasion resistance is considerably greater than the material of the remaining part of the foot plate 53. This Plastic molded part is molded into the footplate during manufacture or, conversely, the remaining part of the footplate 53 is molded onto this plastic molded part. To improve the anchoring of the molded plastic part in the base plate 53, additional anchoring elements can be molded on the outside of the molded plastic part.
