Abstract

The device has a housing (10) anchored in the ground, with an electric turning drive motor (14) to pivot a barrier (12) between vertical and blocking positions. The barrier is connected to a screw drive of spindle (18) and nut (20), and to drive rods (22,24). The axis of the joint (66) between the drive rods and the barrier extends through the vertical plane of the pivot axis of the barrier. The barrier is held in upright position without play or limited play, by stop surfaces (50,32) acting with it and/or parts of its drive train (18-24), and/or is pivoted by play in the drive train into a position 3-5[deg] off its horizontal position, after ending the lowering movement.

Description

Die Erfindung betrifft eine Absperrvorrichtung für Parkplätze und Grundstückseinfahrten mit einem in einem am Boden befestigbaren Gehäuse gelagerten, elektrischen Drehantriebsmotor, durch den über ein aus einer Schraubenspindel und einer Mutter bestehendes Schraubgetriebe und ein Schubgestänge ein gelenkig mit diesem verbundenes, schwenkbar gelagertes Absperrelement zwischen einer im wesentlichen flach liegenden und einer aufgerichteten Endstellung verschwenkbar ist.The invention relates to a shut-off device for parking lots and property entrances with a mounted in a floor mountable housing, electric rotary drive motor through which a screw from a screw and a nut existing helical gear and a push rod a hinged thereto, pivotally mounted shut-off element between a substantially lying flat and an erect end position is pivotable.

Derartige Absperrvorrichtungen sind in großer Zahl bekannt. Das Gebrauchsmuster 87 13 254 beschreibt z. B. einen Pfosten, der durch einen darin montierten Motor mit Schraubgetriebe aufzurichten ist, wofür Strom aus einem öffentlichen Netz benutzt wird. Im Freien ist jedoch oft kein Stromanschluß vorhanden. Bei einer Reihe von nebeneinander liegenden Parkplätzen bietet außerdem ein einzelner Pfosten pro Parkplatz keine Gewähr, daß nicht fremde Autos zwischen den Pfosten parken. Um dies zu verhindern, sollten die Absperrelemente wenigstens etwa 80 cm breit sein. Es ist deshalb bekannt, durch einen Elektromotor mit Schraubgetriebe schwenkbar angetriebene Absperrelemente in Gestalt portalförmiger Bügel zu benutzen.Such shut-off devices are known in large numbers. The utility model 87 13 254 describes z. As a post, which is to be erected by a mounted therein motor with helical gear, which is used for power from a public network. However, outdoors there is often no power connection. In addition, for a number of adjacent car parks, a single post per parking space does not guarantee that strangers will park between the posts. To prevent this, the shut-off should be at least about 80 cm wide. It is therefore known to use by an electric motor with screw gear pivotally driven shut-off in the form of portal-shaped bracket.

Wenn Strom aus einem öffentlichen Netz zur Verfügung steht, können sowohl die Absperrelemente als auch der Antriebsstrang fest und dementsprechend schwer ausgebildet werden, weil ein entsprechend dimensionierter elektrischer Drehantriebsmotor eingesetzt werden kann. Probleme ergeben sich jedoch, wenn man für den Antrieb der Absperrelemente auf die Energieversorgung aus Batterien und Akkumulatoren angewiesen ist, die bis zum Wiederaufladen oder Ersatz wenigstens 3 Monate halten sollten. Dann müssen zur Minimierung des Stromverbrauchs möglichst kleine Massen über möglichst kurze Wege mit möglichst wenig Reibung bewegt werden. Andererseits muß aber gewährleistet bleiben, daß das Absperrelement selbst und sein Antrieb so robust sind, daß sie durch versehentliches und sogar absichtliches Anfahren, wenigstens wenn dabei das Fahrzeug unbeschädigt bleiben soll, nicht zerstört werden. Die Notwendigkeit ausreichender Festigkeit und die aus einer begrenzten Energiequelle resultierenden Anforderungen verlangen prinzipiell gegensätzliche Maßnahmen.When power is available from a public grid, both the shut-off elements and the powertrain can be solid and accordingly heavy because a suitably dimensioned rotary electric motor can be used. Problems arise, however, if one is dependent for the drive of the shut-off on the power supply from batteries and accumulators, the until recharging or replacement should last at least 3 months. Then, in order to minimize the power consumption, the smallest possible masses have to be moved over as short a path as possible with as little friction as possible. On the other hand, it must be ensured that the shut-off itself and its drive are so robust that they are not destroyed by accidental and even deliberate start, at least if the vehicle is to be undamaged. The need for sufficient strength and the requirements resulting from a limited source of energy require in principle conflicting measures.

Aus der US-A-4,901,071 ist eine Absperrvorrichtung bekannt, bei der durch einen Elektromotor über ein normales Untersetzungsgetriebe und ein Schubgestänge ein gelenkig mit diesem verbundenes Absperrelement zwischen einer liegenden und einer durch Anschlag begrenzten aufrechten Stellung verschwenkbar ist. Dabei durchquert die Achse des Gelenks zwischen dem Schubgestänge und dem Absperrelement die senkrechte Ebene durch dessen Schwenkachse in einer der aufrechten Stellung angenäherten Lage. Das Absperrelement läßt sich zur Vermeidung von Schäden leicht aus der aufrechten Stellung abwärts schwenken, wobei ein Alarmsignal ausgelöst wird.From US-A-4,901,071 a shut-off device is known in which by means of an electric motor via a normal reduction gear and a push rod an articulated connected thereto shut-off between a horizontal and limited by stop limited upright position. In this case, traverses the axis of the joint between the push rod and the shut-off the vertical plane through the pivot axis in an upright position approximated position. The shut-off can be easily swivel down from the upright position to avoid damage, with an alarm signal is triggered.

Der Erfindung liegt die Aufgabe zugrunde, eine Absperrvorrichtung der eingangs genannten Art zu schaffen, die in der Lage ist, mit einem verhältnismäßig kleinen elektrischen Drehantriebsmotor mit geringem Energieverbrauch ein breites, festes Absperrelement und einen auch starken, stoßartigen Belastungen gewachsenen Antriebsstrang zu bewegen.The invention has for its object to provide a shut-off device of the type mentioned, which is able to move with a relatively small electric rotary drive motor with low energy consumption a wide, solid shut-off and a strong, jerky loads grown powertrain.

Vorstehende Aufgabe wird durch die Kombination der im Patentanspruch 1 genannten Merkmale gelöst. Dabei dient das erste kennzeichnende Merkmal der Gewinnung eines kurzen Antriebsweges des Schubgestänges mit minimalen Hubbewegungen. Ein weiterer Vorteil besteht darin, daß für die Absperrvorrichtung eine Konstruktion mit minimaler Bauhöhe gewählt werden kann.The above object is achieved by the combination of the features mentioned in claim 1. In this case, the first characteristic feature of the recovery of a short drive path of the push rod with minimal lifting movements. Another advantage is that for the shut-off a construction with a minimum height can be selected.

Das weitere Merkmal, wonach die Schraubenspindel mit einer ersten Anschlagfläche ausgebildet ist, die mit einer zugeordneten gehäuseseitigen Gegenfläche derart zusammenwirkt, daß in der aufgerichteten Endstellung des Absperrelements die Reaktionskraft seines Andrucks oder des Andrucks eines Teils des Schubgestänges gegen einen Anschlag durch die erste Anschlagfläche an der zugeordneten Gegenfläche abstützbar und das Absperrelement spielfrei oder mit begrenztem Spiel in aufgerichteter Stellung gehalten ist, löst das Problem der Abschirmung des motorischen Antriebs und eines ggf. angeschlossenen Getriebes gegenüber möglicherweise auf das aufgerichtete Absperrelement wirkenden rohen Kräften.The further feature, according to which the screw is formed with a first stop surface which cooperates with an associated housing-side mating surface such that in the erected end position of the shutoff the reaction force of his Andrucksruck or a part of the push rod against a stop by the first stop surface on the assigned mating surface supportable and the shut-off is held without play or with limited play in an upright position, solves the problem of shielding the motor drive and possibly connected transmission against possibly acting on the erected shut-off raw forces.

In entsprechender Weise kann die flach liegende Endstellung des Absperrelements gesichert sein, indem die Schraubenspindel begrenzt axial verschieblich gelagert und mit einer entgegengesetzt zur ersten Anschlagfläche gerichteten zweiten axialen Anschlagfläche ausgebildet ist, zwischen den beiden Anschlagflächen mit axialem Spiel jeweils zugeordnete gehäuseseitige Gegenflächen angeordnet sind und in der liegenden Endstellung des Absperrelements die Reaktionskraft seines Andrucks oder des Andrucks eines Teils des Schubgestänges gegen einen Anschlag durch die zweite Anschlagfläche an der zugeordneten Gegenfläche abstützbar ist.In a corresponding manner, the flat lying end position of the shutoff can be secured by the screw spindle limited axially displaceable and formed with a second stop surface directed opposite to the first stop surface, between the two stop surfaces with axial clearance respectively associated housing side mating surfaces are arranged and in the lying end position of the shutoff the reaction force of his Andrucks or the pressure of a portion of the push rod against a stop by the second stop surface on the associated counter surface is supported.

Manchmal sind Stöße gegen das aufgerichtete Absperrelement nicht zu befürchten, aber es ist mit Frost oder losen Steinen zu rechnen, die gelegentlich das vollständig flache Umlegen des Absperrelements verhindern. Unter solchen Umständen besteht die Gefahr, daß ein mit einem Rad über das nicht vollständig abgesenkte Absperrelement rollendes Fahrzeug den Antriebsstrang des Absperrelements oder dieses selbst und seine Lagerung überlastet. Als Gegenmaßnahme ist erfindungsgemäß vorgesehen, daß der Antriebsstrang soviel Spiel hat, daß das Absperrelement nach dem Anhalten der Absenkbewegung, in einer der liegenden angenäherten Stellung um mindestens etwa 3 - 5° weiter zur flach liegenden Stellung hin schwenkbar ist. Am besten gesichert ist die Absperrvorrichtung, wenn sie über beide vorgenannten Sicherungsmaßnahmen verfügt, nämlich die feste oder begrenzt bewegliche Einspannung des Absperrelements in der aufgerichteten Stellung und die Nachgiebigkeit des Antriebsstrangs bei nicht ganz abgesenktem Absperrelement.Sometimes impacts against the upright shut-off element are not to be feared, but frost or loose stones are to be expected, which occasionally prevent the completely flat turning over of the shut-off element. In such circumstances, there is a risk that a vehicle rolling with a wheel over the shut-off element which is not fully lowered will overload the drive train of the shut-off element or the latter itself and its storage. As a countermeasure, the invention provides that the drive train has so much game that the shut-off after stopping the lowering movement, in one of the lying approximate position by at least about 3 - 5 ° further to the flat lying position is pivotally. The most secure is the shut-off device, if it has both aforementioned safety measures, namely the fixed or limited movable clamping of the shutoff in the raised position and the compliance of the drive train with not completely lowered shut-off.

Normalerweise wird man, wenn ein Absperrelement zwischen einer flach liegenden und einer aufgerichteten Stellung zu verschwenken ist, einen Schwenkbereich von 90° vorsehen. Demgegenüber wird in bevorzugter Ausgestaltung der Erfindung vorgeschlagen, daß das Absperrelement nur über einen Winkelbereich von etwa 65 - 80° aufgerichtet wird. Im letzten Teil einer sich über 90° erstreckenden Aufrichtbewegung wird nur noch wenig Höhe gewonnen, aber die Batterie müßte bei jedem Aufricht- und Absenkvorgang Energie für einen wesentlich längeren Schwenkweg liefern.Normally, when a shut-off element is to be pivoted between a flat and an upright position, one will provide a pivoting range of 90 °. In contrast, it is proposed in a preferred embodiment of the invention that the shut-off is erected only over an angular range of about 65 - 80 °. In the last part of an erecting movement extending over 90 °, only little height is gained, but the battery would have to supply energy for a significantly longer pivoting path with each raising and lowering operation.

Erfindungsgemäß durchquert bei der Schwenkbewegung des Absperrelements im mittleren Schwenkbereich das Gelenk zwischen dem Schubgestänge und dem Absperrelement die senkrechte Ebene durch dessen Schwenkachse. Dabei besteht die Möglichkeit, unabhängig von der Größe des Schwenkbereichs diesen Durchgang durch die senkrechte Ebene durch die Schwenkachse genau auf die Mitte des Schwenkbereichs zu legen. Dann kann das Schubgestänge in beiden Endstellungen horizontal liegen. Vorgezogen wird jedoch eine asymmetrische Teilung des Schwenkbereichs in einen längeren Abschnitt bis zur Durchquerung der senkrechten Ebene durch die Schwenkachse des Absperrelements und einen kürzeren Abschnitt zwischen dieser Durchgangsposition und der aufgerichteten Endstellung. In diesem Fall ergibt sich der Vorteil, daß in der flach liegenden Ausgangsstellung des Absperrelements auch das Schubgestänge optimal flach, d. h. horizontal liegen kann, aber in der aufgerichteten Endstellung ganz oder teilweise eine zum Gelenk zwischen dem Absperrelement und dem Schubgestänge hin ansteigende. Lage hat. Diese gestattet eine teilweise Abstützung der auf das aufgerichtete Absperrelement wirkenden Kräfte schon durch das anschließende, schräg stehende Teil des Schubgestänges am Gehäuse.According to the invention, during the pivotal movement of the shut-off element in the central pivoting range, the joint between the pushrod and the shut-off element passes through the vertical plane through its pivot axis. It is possible, regardless of the size of the swivel range to lay this passage through the vertical plane through the pivot axis exactly to the center of the swivel range. Then the push rod can be horizontal in both end positions. However, preference is given to an asymmetrical division of the pivoting area into a longer section until it traverses the vertical plane through the pivot axis of the blocking element and a shorter section between this passage position and the erected end position. In this case, there is the advantage that in the flat lying starting position of the shut-off and the push rod optimal flat, d. H. can lie horizontally, but in the erected end position wholly or partially rising to the joint between the shut-off and the push rod out. Location has. This allows a partial support of the forces acting on the upright shut-off forces already by the subsequent, inclined part of the push rod on the housing.

Um den Verschiebeweg des Schubgestänges kurz zu halten und die maximale Höhe des Gelenks zwischen dem Schubgestänge und dem Absperrelement während dessen Schwenkbewegung zu begrenzen, sollte in weiterer bevorzugter Ausgestaltung der Erfindung der Abstand zwischen der Achse dieses Gelenks und der Schwenkachse höchstens etwa 50 % größer sein als die Bauhöhe des Absperrelements im flach liegenden Zustand, vorzugsweise etwa ebenso groß wie diese.In order to keep the displacement of the push rod short and to limit the maximum height of the joint between the push rod and the shut-off during its pivotal movement, in a further preferred embodiment of the invention, the distance between the axis of this joint and the pivot axis should be at most about 50% greater than the height of the shutoff in the flat state, preferably about as large as this.

Besondere Überlegungen gelten dem Schraubgetriebe, das die rotierende Bewegung des elektrischen Antriebsmotors in eine im wesentlichen translatorische Bewegung für das Schubgestänge umsetzt. Schraubgetriebe haben grundsätzlich den Nachteil einer verhältnismäßig hohen Reibung. Bei einer üblichen Gewindesteigung, die wesentlich kleiner ist als der Durchmesser der Gewindespindel, hat das Schraubgetriebe Selbsthemmung. Das größte Problem entsteht dadurch, daß das Absperrelement am Ende der Schwenkbewegung nicht nur mit dem Drehmoment des elektrischen Antriebsmotors, sondern mit der kinetischen Energie aller bewegten Teile hart gegen einen Anschlag fährt. Beim Anfahren in Rückwärtsrichtung steht aber nur das schwache Drehmoment des möglichst klein zu wählenden Elektromotors zur Verfügung. Erschwerend kommt hinzu, daß wegen der geforderten hohen Festigkeit gegenüber stoßartiger Belastung des Absperrelements die Gewindespindel einen verhältnismäßig großen Durchmesser von mindestens 12, möglichst mindestens 16 mm haben sollte, so daß die Reibungskräfte und die durch das Fahren gegen einen Anschlag erzeugten Klemmkräfte im Schraubgetriebe auf einem verhältnismäßig großen Radius an der drehschlüssig mit dem Motor verbundenen Gewindespindel angreifen.Special considerations apply to the helical gear, which converts the rotating movement of the electric drive motor in a substantially translational movement for the push rod. Screw gear basically have the disadvantage of relatively high friction. In a conventional thread pitch, which is substantially smaller than the diameter of the threaded spindle, the helical gear has self-locking. The biggest problem arises from the fact that the shut-off at the end of the pivoting movement drives hard against a stop not only with the torque of the electric drive motor, but with the kinetic energy of all moving parts. When starting in the reverse direction but only the weak torque of the smallest possible to be selected electric motor is available. To make matters worse, that because of the required high strength against jerky loading of the shutoff the threaded spindle should have a relatively large diameter of at least 12, preferably at least 16 mm, so that the frictional forces and the clamping forces generated by driving against a stop in the helical gear on a attack relatively large radius on the rotationally connected to the motor threaded spindle.

Den Schlüssel zur Lösung dieses komplizierten Problems sieht die Erfindung in der Gestaltung der Schraubenspindel. Es wird vorgeschlagen, eine sehr große Gewindesteigung zu wählen, die auf jeden Fall größer als etwa 2/3 des Spindeldurchmessers, vorzugsweise mehr als ¾ des Spindeldurchmessers, betragen sollte. In der bevorzugten praktischen Ausführung ist die Gewindesteigung etwa so groß wie der Durchmesser der Spindel, so daß z.B. bei einem Spindeldurchmesser von 16 mm eine einzige Umdrehung der Spindel zu einer Verschiebung des Schubgestänges um 16 mm führt. In weiterer bevorzugter Ausgestaltung der Erfindung ist die Schraubenspindel trotz der großen Gewindesteigung nur mit einem einzigen Gewindegang ausgebildet, wobei dieser vorzugsweise einen rechteckigen Querschnitt hat. Zusätzlich empfiehlt sich im Zusammenwirken mit der Mutter ein Gewindespiel, das wesentlich größer ist als das normgerechte Spiel.The key to solving this complicated problem sees the invention in the design of the screw. It is suggested to choose a very large thread pitch than about / the spindle diameter should preferably be more than ¾ of the spindle diameter, definitely greater than 2 3. In the preferred practical embodiment, the thread pitch is about as large as the diameter of the spindle, so that, for example, with a spindle diameter of 16 mm a single revolution of the spindle to a displacement of the push rod leads by 16 mm. In a further preferred embodiment of the invention, the screw is formed despite the large pitch only with a single thread, which preferably has a rectangular cross-section. In addition, in conjunction with the nut, a thread play is recommended, which is much larger than the standard-compliant game.

Durch die große Gewindesteigung, ggf. flankiert von den weiteren vorstehend genannten Maßnahmen, wird unabhängig von der übrigen Ausbildung der Absperrvorrichtung erreicht, daß das Schraubgetriebe im Grenzbereich der Selbsthemmung liegt, nach Möglichkeit ein wenig außerhalb davon, so daß die beim Anschlagen des Absperrelements gegen den Endanschlag im Schubgestänge und Schraubgetriebe erzeugte axiale Verspannung den elektrischen Antriebsmotor beim Anlaufen in Rückwärtsrichtung unterstützt. Der Grundgedanke eines Schraubgetriebes mit einer Gewindesteigung in der angegebenen Größe kann auch bei anderen Geräten Anwendung finden.Due to the large thread pitch, possibly flanked by the other measures mentioned above, regardless of the rest of the formation of the shut-off ensures that the helical gear is in the limit of self-locking, if possible, a little outside of it, so that when hitting the shutoff against the End stop in the push linkage and helical gear generated axial tension supports the electric drive motor when starting in the reverse direction. The basic idea of a helical gear with a pitch in the specified size can also be found in other devices application.

Die ein Vielfaches größer als normal gewählte Gewindesteigung bedingt eine entsprechend vervielfachte Untersetzung der Drehzahl des elektrischen Antriebsmotors durch ein mit diesem verbundenes Getriebe, vorzugsweise ein Zahnradgetriebe. Die tatsächlich notwendige Untersetzung richtet sich nach der Verfügbarkeit geeigneter elektrischer Antriebsmotoren. Wenn die zur Zeit verfügbaren sparsamen Elektromotoren mit Drehzahlen im Bereich von mehr als 15.000 U/min betrieben werden, wird ein Getriebe mit einer Drehzahluntersetzung von 80 : 1 bis 120 : 1 eingesetzt. Wenn ebenso sparsame elektrische Antriebsmotoren mit niedrigerer Drehzahl erhältlich sind, kann das Getriebe entsprechend reduziert werden.The multiply greater than normally selected thread pitch causes a correspondingly multiplied reduction of the rotational speed of the electric drive motor by a gear connected to this, preferably a gear transmission. The actual necessary reduction depends on the availability of suitable electric drive motors. If the currently available economical electric motors are operated at speeds in the range of more than 15,000 rpm, a transmission with a speed reduction of 80: 1 to 120: 1 is used. If equally economical electric drive motors are available at a lower speed, the transmission can be reduced accordingly.

Wegen der für eine erfindungsgemäße Absperrvorrichtung notwendigen niedrigen Bauhöhe von insgesamt maximal 12 cm, vorzugsweise nur etwa 8 - 10 cm, und wegen des geforderten niedrigen Energieverbrauches kann nur ein im Durchmesser kleiner Motor von etwa 3 - 4 cm Durchmesser und ein entsprechend kleines Getriebe zum Einsatz kommen. Um letzteres nicht der starken, stoßartigen Belastung beim Anschlagen des Absperrelements an die Endanschläge auszusetzen, ist in einer bevorzugten praktischen Ausführung der Erfindung vorgesehen, daß die aus dem Drehantriebsmotor und dem Untersetzungsgetriebe bestehende Einheit fliegend auf der Schraubenspindel gelagert und durch ein Federelement gegen Drehung gehalten ist. Auf diese Weise kann die Motor-Getriebeeinheit im Moment des Anschlags in Drehrichtung des Rotors noch weiter rotieren und wird bei dieser Bewegung durch das Federglied weich abgebremst. Dies wirkt sich auch positiv auf die Verklemmung des Absperrelements und seines Antriebsstrangs mit dem Gehäuse bei Erreichen einer der Endstellungen aus. Die Verkeilung ist schwächer und läßt sich daher auch leichter lösen.Because of the necessary for a shut-off device according to the invention low overall height of a maximum of 12 cm, preferably only about 8 - 10 cm, and because of the required low energy consumption, only a small diameter motor of about 3 - 4 cm in diameter and a correspondingly small gear is used come. In order not to suspend the latter, the strong, shock-like loading when striking the Absperrelements to the end stops, is provided in a preferred practical embodiment of the invention that the consisting of the rotary drive motor and the reduction gear unit is mounted on the screw and supported by a spring element against rotation , In this way, the motor-gear unit at the moment of the stop in the direction of rotation of the rotor rotate even further and is softly braked during this movement by the spring member. This also has a positive effect on the jamming of the shut-off element and its drive train with the housing when one of the end positions is reached. The wedging is weaker and therefore easier to solve.

Es ist zweckmäßig, die Mutter gleichzeitig als gelenkig mit dem Absperrelement zu verbindende Schubstange oder als Teil eines Schubgestänges auszubilden. Sie kann hierzu in einfacher Weise als Gewindebuchse geeigneter Länge ausgebildet sein. Wenn der Dichtigkeit des den elektrischen Antriebsmotor und das Getriebe aufnehmenden Gehäuses Vorrang eingeräumt wird, empfiehlt es sich, die mit der Mutter verbundene Schubstange über eine an ihrem freien Ende gelenkig angebrachte Koppel mit dem Absperrelement zu verbinden. Diese Konstruktion bietet die Möglichkeit, die Schubstange nur axial zu bewegen, so daß die Gehäusebohrung, durch die sie nach außen zur Koppel geführt ist, in einfacher Weise abgedichtet werden kann. Wenn dagegen die Einfachheit der Konstruktion größere Bedeutung hat, kann auch die einstückig mit der Mutter ausgebildete Schubstange direkt gelenkig mit dem Absperrelement verbunden sein. Bei dieser Ausführung ist die Schraubenspindel begrenzt schwenkbar zu lagern, z.B. in einer Querbohrung eines drehbar im Gehäuse gelagerten Bolzens oder eines mit diesem verbundenen Teils. Grundsätzlich besteht auch die Möglichkeit, statt der Schraubenspindel die Mutter rotierend anzutreiben. In diesen Fall ist die Schraubenspindel mit der Koppel oder dem Absperrelement gelenkig verbunden.It is expedient to form the nut at the same time as articulated to be connected to the shut-off push rod or as part of a push rod. It can be designed for this purpose in a simple manner as a threaded bushing of suitable length. If the tightness of the electrical drive motor and the gear housing receiving priority is given, it is recommended that the push rod connected to the mother to connect via a hinged at its free end coupling with the shut-off. This construction offers the possibility to move the push rod only axially, so that the housing bore, through which they outwardly to Coupling is guided, can be sealed in a simple manner. In contrast, if the simplicity of the construction has greater importance, and the integrally formed with the mother push rod can be directly hinged to the shut-off. In this embodiment, the screw is limited pivotally store, for example in a transverse bore of a rotatably mounted in the housing bolt or a part connected to this. In principle, there is also the possibility of rotating the nut instead of the screw spindle. In this case, the screw is hinged to the coupling or shut-off.

Unabhängig davon, wie man den Antriebsstrang gestaltet, ist es im Hinblick auf den Energieverbrauch zweckmäßig, ein Absperrelement zu wählen, das in aufgeschwenkter Stellung eine im wesentlichen V-förmige Gestalt hat und oben mindestens ca. 80 cm breit ist. Dieser Vorschlag beruht auf der Erkenntnis, daß man nur im oberen Bereich die notwendige Mindestbreite braucht, um Fahrzeuge an der Ein- oder Durchfahrt zu hindern. Die Verjüngung des Absperrelements zu seinem Schwenklager hin gestattet eine Minimierung der zu verschwenkenden trägen Masse. Dem gleichen Zweck kann eine Verjüngung der beiden Arme des V-förmigen Absperrelements zu ihren freien Enden hin dienen.Regardless of how to design the drive train, it is appropriate in terms of energy consumption, to choose a shut-off, which has a substantially V-shaped configuration in the pivoted position and above at least about 80 cm wide. This proposal is based on the recognition that only in the upper part of the necessary minimum width needed to prevent vehicles at the entrance or transit. The taper of the shut-off element towards its pivot bearing allows a minimization of the inertial mass to be pivoted. For the same purpose can serve a taper of the two arms of the V-shaped shutoff to their free ends.

Eine weitere Minderung des notwendigen motorischen Drehmoments wird bei der bevorzugten praktischen Ausführungsform der Erfindung durch eine zur aufgerichteten Stellung des Absperrelements hin wirkende Feder erzielt, die einen Gewichtsausgleich bewirkt.A further reduction of the necessary motor torque is achieved in the preferred practical embodiment of the invention by acting on the erected position of the shut-off spring, which causes a weight balance.

Die in Fig. 1 - 4 in ihrer Gesamtheit gezeigte Absperrvorrichtung hat ein insgesamt mit 10 bezeichnetes Gehäuse, an dem ein Absperrelement 12 zwischen einer in Fig. 2 gezeigten, flach liegenden Stellung und der in Fig. 1 gezeigten, aufgerichteten Stellung verschwenkbar gelagert ist. Als Antrieb für die Schwenkbewegung dient ein elektrischer Antriebsmotor 14, der über ein Drehzahl-Untersetzungsgetriebe 16, eine Gewindespindel 18, eine Mutter 20, eine mit dieser einstückig ausgebildete Schubstange 22 und mit dieser gelenkig verbundene Koppeln 24 auf das damit gelenkig verbundene Absperrelement 12 wirkt. Das Gehäuse 10 nimmt neben dem elektrischen Antriebsmotor 14, dem Getriebe 16 und dem Schraubgetriebe 18, 20 auch noch einen Akkumulator auf, so daß die Vorrichtung nicht auf das Vorhandensein eines elektrischen Netzanschlusses angewiesen ist. Das Verschwenken des Absperrelements 12 aus der unwirksamen Stellung nach Fig. 2 in die Sperrstellung nach Fig. 1 soll nicht länger als ca. 5 sek dauern.The shut-off device shown in its entirety in FIGS. 1-4 has a housing, generally designated 10, on which a shut-off element 12 is pivotably mounted between a flat position shown in FIG. 2 and the erected position shown in FIG. The drive for the pivoting movement is an electric drive motor 14 which acts via a speed reduction gear 16, a threaded spindle 18, a nut 20, an integrally formed with this push rod 22 and articulated with this coupling 24 on the thus connected shut-off valve 12. The housing 10 takes in addition to the electric drive motor 14, the gear 16 and the helical gear 18, 20 also an accumulator, so that the device is not dependent on the presence of an electrical power supply. The pivoting of the shut-off element 12 from the inoperative position of FIG. 2 in the blocking position of FIG. 1 should not last longer than about 5 seconds.

Fig. 4 zeigt, daß das Absperrelement 12 im flach auf dem Boden liegenden Zustand in Draufsicht, also auch in der aufgerichteten Stellung nach Fig. 1, eine V-förmige Gestalt hat, wobei sich die beiden Arme bzw. Schenkel des "V" zu ihren freien Enden hin verjüngen. Die Länge der Arme des Absperrelements 12 kann z. B. etwa 50 cm betragen, und der Winkel zwischen den beiden Armen beträgt im Ausführungsbeispiel etwa 90°.Fig. 4 shows that the shut-off element 12 in flat lying on the ground state in plan view, including in the erected position of FIG. 1, a V-shaped configuration, with the two arms or legs of the "V" to to rejuvenate their free ends. The length of the arms of the shut-off element 12 may, for. B. be about 50 cm, and the angle between the two arms is in the embodiment about 90 °.

Weiterhin ist aus Fig. 4 ersichtlich, daß zwei parallel angeordnete Koppeln 24 zur gelenkigen Verbindung der Schubstange 22 mit dem Absperrelement 12 vorhanden sind. Schließlich lassen die Figuren 3 und 4 eine auf der mit 26 bezeichneten Schwenkachse des Absperrelements 12 sitzende Feder 28 erkennen, die bestrebt ist, das Absperrelement 12 in die Stellung nach Fig. 1 aufzurichten.Furthermore, it can be seen from Fig. 4 that two parallel arranged coupling 24 for articulated connection of the push rod 22 with the shut-off element 12 are present. Finally, FIGS. 3 and 4 show a spring 28 seated on the pivot axis 26 of the shutoff element 12, which endeavors to erect the shutoff element 12 into the position according to FIG.

Zu weiteren Einzelheiten der Konstruktion der Absperrvorrichtung nach Fig. 1 - 4 wird auf die in größerem Maßstab gehaltenen Darstellungen nach Fig. 5 - 8 Bezug genommen. Danach besteht das Gehäuse 10 aus einem kastenförmigen Unterteil 30, das durch eine Zwischenwand 32 in eine vordere Kammer 34 und eine hintere Kammer 36 unterteilt und durch einen Deckel 38 oberseitig dicht abgeschlossen ist. Die hintere Kammer 36 nimmt den elektrischen Antriebsmotor 14, das Getriebe 16 sowie einen nicht gezeigten Akkumulator auf. Die vordere Kammer 34 enthält das Schraubgetriebe, bestehend aus der Gewindespindel 18 und der Mutter 20. Im Boden wenigstens einer der Kammern 34, 36 befinden sich Befestigungslöcher zur Verankerung des Gehäuses 10. Die Gewindespindel 18 ist in der Zwischenwand 32 drehbar, aber axial nur ein wenig verschiebbar gelagert. Sie trägt auf ihrem hinteren, in die hintere Kammer 36 ragenden Ende über eine feste Verbindung mit der Abtriebswelle des Untersetzungsgetriebes 16 die auf diese Weise fliegend gelagerte Motor-Getriebe-Einheit 14, 16. Damit diese die Gewindespindel 18 wahlweise in die eine oder andere Richtung rotierend antreiben kann, ist das mit dem Motorgehäuse fest verbundene Getriebegehäuse am vorderen Stirnende mit einem Vorsprung 40 ausgebildet, der sich gemäß Fig. 5 und 8 durch einen Gummiring 42 erstreckt, der seinerseits durch einen in ihn eingreifenden, an der Zwischenwand 32 befestigten Bolzen 44 festgelegt ist. Diese Lagerung der Motor-Getriebe-Einheit 14, 16 gestattet eine begrenzte Drehbewegung derselben um die Drehachse der Gewindespindel 18 und eine elastische Abbremsung von auf die Motor-Getriebe-Einheit 14, 16 wirkenden Drehmomentschlägen. Die elastische Halterung der Motor-Getriebe-Einheit mittels des Gummirings 42 gestattet auch eine begrenzte axiale Verschiebung zusammen mit der Gewindespindel 18. Sie ist begrenzt durch fest mit der Gewindespindel 18 verbundene Anschläge 46 und 48 auf beiden Seiten der Zwischeriwand 32, die mit deren Flächen als Gegenflächen zusammenwirken.For further details of the construction of the shut-off device of Figs. 1-4, reference is made to the larger scale illustrations of Figs. 5-8. Thereafter, the housing 10 consists of a box-shaped lower part 30, which is divided by an intermediate wall 32 in a front chamber 34 and a rear chamber 36 and sealed by a lid 38 on top. The rear chamber 36 receives the electric drive motor 14, the gear 16 and a battery, not shown. The front chamber 34 contains the helical gear, consisting of the threaded spindle 18 and the nut 20. In the bottom of at least one of the chambers 34, 36 are mounting holes for anchoring the housing 10. The threaded spindle 18 is rotatable in the intermediate wall 32, but only one axially stored slightly displaceable. It carries on its rear, projecting into the rear chamber 36 via a fixed connection with the output shaft of the reduction gear 16 in this way cantilevered motor-gear unit 14, 16. So that the threaded spindle 18 either in one or the other direction can rotate, the gear housing fixedly connected to the motor housing is formed at the front end with a projection 40 which extends as shown in FIG. 5 and 8 by a rubber ring 42, in turn, by an engaging in him, attached to the intermediate wall 32 bolts 44 is fixed. This mounting of the motor-gear unit 14, 16 allows a limited rotational movement of the same about the axis of rotation of the threaded spindle 18 and an elastic braking of torque acting on the motor-gear unit 14, 16 torque beats. The elastic mounting of the motor-gear unit by means of the rubber ring 42 also allows a limited axial displacement together with the threaded spindle 18. It is limited by fixedly connected to the threaded spindle 18 stops 46 and 48 on both sides of Zwischemiwand 32, with their surfaces interact as counter surfaces.

Wie in Fig. 5 dargestellt, hat die Gewindespindel 18 ein eingängiges Rechteckgewinde, dessen Steigung etwa ebenso groß ist wie der Durchmesser der Spindel und im Ausführungsbeispiel 16 mm beträgt.As shown in Fig. 5, the threaded spindle 18 has a catchy rectangular thread whose pitch is about as large as the diameter of the spindle and in the embodiment is 16 mm.

Die Mutter 20 ist mit der Schubstange 22 integriert. Beide, Teile sind gebildet durch eine Gewindebuchse mit einer mit Innengewinde versehenen Sackbohrung, die ausreichend lang ist, um die Gewindespindel 18 auf der mit Gewinde versehenen Länge aufzunehmen. Das Innengewinde kann aber wesentlich kürzer sein als die Sackbohrung. Die Gewindebuchse 20, 22 erstreckt sich durch eine Bohrung in der Vorderwand des Gehäuses 10 nach außen und ist in dieser Bohrung, deren Achse mit derjenigen der Bohrung in der Zwischenwand 32 fluchtet, in der die Gewindespindel 18 drehbar gelagert ist, axial verschieblich geführt. Die miteinander fluchtenden Mittellängsachsen der Gewindespindel 18 und der Gewindebuchse 20, 22 liegen nach der Montage der Absperrvorrichtung im wesentlichen horizontal. Die äußere Gehäusebohrung paßt zum Außendurchmesser der Gewindebuchse 20, 22 und ist vom Deckel 38 überdeckt, so daß von außen praktisch kein Wasser in das Gehäuse 10 eindringt. Falls dies dennoch durch unvorhersehbare Einflüsse geschieht, kann es durch ein nicht gezeigtes Loch im Boden oder im unteren Bereich der Vorder- oder einer Seitenwand wieder auslaufen.The nut 20 is integrated with the push rod 22. Both parts are formed by a threaded bush having an internally threaded blind bore which is sufficiently long to receive the threaded spindle 18 on the threaded length. The internal thread can be much shorter than the blind hole. The threaded bushing 20, 22 extends through a hole in the front wall of the housing 10 to the outside and is guided axially displaceably in this bore whose axis is aligned with that of the bore in the intermediate wall 32 in which the threaded spindle 18 is rotatably mounted. The mutually aligned central longitudinal axes of the threaded spindle 18 and the threaded bushing 20, 22 are after installation of the shut-off device substantially horizontally. The outer housing bore fits the outer diameter of the threaded bushing 20, 22 and is from the lid 38th covered, so that virtually no water from entering into the housing 10 from the outside. However, if this happens due to unpredictable influences, it may leak through a hole in the bottom or bottom of the front or side wall, not shown.

Zum Gehäuse 10 gehört auch noch ein fest mit der Vorderwand verbundener, sich von dieser nach vorn erstreckender Trägerholm 50 mit U-förmigem, unten offenen Querschnitt. Auf seiner Oberseite ist eine Gleitplatte 52 angebracht, auf der die mit der Mutter 20 vereinigte Schubstange 22 verschieblich geführt ist. Außerdem erstreckt sich in einem Abstand zur Vorderwand, der etwa der Länge der Gewindebuchse 20, 22 entspricht, ein Bolzen 54 durch miteinander fluchtende Querbohrungen im unteren Bereich des Trägerholms 50. Die Mittellängsachse des Bolzens 54 bildet die Schwenkachse 26 des Absperrelements 12. Dieses übergreift mit vorderen Wangen 56, in deren unteren Bereichen sich ebenfalls zum Durchmesser des Bolzens 54 passende Querbohrungen befinden, den Trägerholm 50. Der Bolzen 54 erstreckt sich mit seinen äußeren Enden auch durch diese Querbohrungen, so daß das Absperrelement 12 auf dem Bolzen 54 gelagert ist. Damit nicht einfach der Bolzen 54 entfernt und dadurch die Sperre beseitigt werden kann, ist er innerhalb des Trägerholms 50 durch Quersplinte 58 axial gesichert.The housing 10 also includes a firmly connected to the front wall, extending from this forwardly extending beam spar 50 with U-shaped, open at the bottom. On its upper side a sliding plate 52 is mounted, on which the united with the nut 20 push rod 22 is guided slidably. In addition, extends at a distance from the front wall, which corresponds approximately to the length of the threaded bushing 20, 22, a bolt 54 by mutually aligned transverse bores in the lower region of the support beam 50. The central longitudinal axis of the bolt 54 forms the pivot axis 26 of the shut-12th This overlaps with front cheeks 56, in the lower regions are also to the diameter of the bolt 54 matching transverse bores, the carrier spar 50. The bolt 54 extends with its outer ends through these transverse bores, so that the shut-off element 12 is mounted on the pin 54. So that not simply removed the bolt 54 and thereby the lock can be eliminated, it is axially secured within the support beam 50 by transverse splint 58.

Die Wangen 56 bilden zusammen mit einem sie verbindenden Quersteg 60 gemäß Fig. 7 ein den Trägerholm 50 übergreifendes, im Querschnitt U-förmiges, auf dem Bolzen 54 schwenkbar gelagertes Grundelement, an das in V-förmiger Anordnung Arme 62 angeschweißt sind, so daß insgesamt das Trägerelement 12 erhalten wird. Die Arme 62 haben einen L-förmigen Querschnitt. In der unwirksamen Stellung liegen sie flach am Boden an und der Quersteg 60 nimmt eine horizontale Lage ein. Er liegt dabei dicht über oder auf der Gewindebuchse 20, 22, die ihrerseits auf der Gleitplatte 52 aufliegt. Somit ist der feste, normalerweise betonierte oder gepflasterte Boden der Endanschlag, der beim Absenken des Absperrelements 12 dessen Endstellung bestimmt. Etwa gleichzeitig und auf jeden Fall, wenn der Boden nachgibt, kommt es auch zum Anschlag an den Gewindebuchsen 20, 22, so daß auch diese den Endanschlag bilden. Die Hinterkante der Wangen 56 ist vom hinteren Ende des Querstegs 60 nach vorne unten, zum Bolzen 54 hin abgeschrägt. Auf diese Weise wird die zu verschwenkende träge Masse verringert und die Klemmgefahr reduziert.The cheeks 56, together with a transverse web 60 connecting them as shown in FIG. 7, a carrier member 50 cross-sectionally U-shaped, pivotally mounted on the bolt 54 basic element to which arms 62 are welded in a V-shaped arrangement, so that total the carrier element 12 is obtained. The arms 62 have an L-shaped cross-section. In the inactive position, they lie flat on the ground on and the crosspiece 60 assumes a horizontal position. He lies close to or on the threaded bushing 20, 22, which in turn rests on the sliding plate 52. Thus, the solid, usually concreted or paved bottom of the end stop, which determines the lowering of the shutoff 12 its end position. About the same time and in any case, when the ground yields, it also comes to a stop on the threaded bushes 20, 22, so that these also form the end stop. The trailing edge of the cheeks 56 is chamfered from the rear end of the crosspiece 60 forward down, toward the bolt 54. In this way, the to be pivoted inertial mass is reduced and reduces the risk of jamming.

Das in Fig. 5 und 6 gestrichelt gezeigte L-förmige Profil der Arme 62 des Absperrelements 12 hat in dessen flach am Boden liegender Stellung eine Lage, in der ein Schenkel senkrecht steht und eine Vorderwand des Absperrelements bildet, während der andere, am oberen Ende des senkrechten Schenkels angrenzende Schenkel eine horizontale Lage hat. Dies gilt allerdings nur für die Darstellung im Querschnitt. In der Frontansicht nach Fig. 7 fällt die von dem oberen Schenkel gebildete Oberseite der Arme 62 zu ihrem freien Ende hin schräg ab. Auch die Breite der oberen Fläche verjüngt sich zum freien Ende der Arme 62 hin, wie die Draufsicht nach Fig. 4 zeigt.The L-shaped profile of the arms 62 of the shutoff element 12 shown in phantom in FIGS. 5 and 6 has, in its position lying flat on the floor, a position in which one leg is perpendicular and forms a front wall of the shutoff element, while the other, at the upper end of the vertical leg adjacent leg has a horizontal position. However, this only applies to the representation in cross section. In the front view of FIG. 7, the upper side of the arms 62 formed by the upper leg slopes obliquely towards its free end. Also, the width of the upper surface tapers towards the free end of the arms 62, as the plan view of FIG. 4 shows.

Auf der Innenseite der Wangen 56 sind Lageraugen 64 angeschweißt, aus denen Lagerzapfen 66 nach innen vorstehen. Auf diesen Lagerzapfen 66 sind die beiden parallel angeordneten Koppeln 24 mit ihrem vorderen Ende drehbar gelagert. Ihr hinteres Ende ist auf entsprechenden Lagerzapfen 68, die nach entgegengesetzten Seiten quer aus der Gewindebuchse 20, 22 vorstehen, drehbar gelagert. Allerdings greifen die Lagerzapfen 68 nicht in passende Bohrungen in den Koppeln 24 ein, sondern in Langlöcher 70..Dadurch erhält das aus der Gewindebuchse 20, 22 und den Koppeln 24 bestehende Schubgestänge ein bestimmtes axiales Spiel von z. B. 3 - 10 mm. Es sollte zweckmäßigerweise ausreichen, um das Absperrelement um ca. 3 - 5° zu verschwenken.On the inside of the cheeks 56 bearing eyes 64 are welded, from which journals 66 protrude inward. On this journal 66, the two parallel coupling 24 are rotatably mounted with its front end. Its rear end is rotatably mounted on corresponding bearing journals 68 which project transversely from the threaded bushing 20, 22 towards opposite sides. However, the journals engage 68 not in matching holes in the coupling 24 a, but in slots 70.Thus receives from the threaded bushing 20, 22 and the coupling 24 existing thrust rod a certain axial play of z. B. 3 - 10 mm. It should expediently be sufficient to pivot the shut-off element by about 3 ° -5 °.

Wenn das Absperrelement durch Ausfahren der Gewindebuchse 20, 22 aus der flach liegenden Stellung nach Fig. 6 in die aufgerichtete Sperrstellung nach Fig. 5 verschwenkt wird, drücken die Lagerzapfen 68 gegen das vordere Ende der Langlöcher 70 der Koppeln 24. Am Ende dieser Aufstellbewegung stößt das Grundelement 56, 60, das in der Ausgangssituation nach Fig. 6 aufrecht gestanden hat, nach einem Schwenkweg von z. B. 70 oder 75° mit der Vorderkante des Querstegs 60 gegen die Oberseite des Trägerholms 50, die somit einen mechanischen Anschlag zur Begrenzung der Schwenkbewegung beim Aufrichten bildet. Die Motorsteuerung ist so gestaltet, daß die größere Stromaufnahme beim Anstoßen gegen einen Endanschlag oder ein Hindernis zum Abschalten des Motors führt. Der harte Aufprall erzeugt einen Drehmomentschlag, dessen Rückwirkung auf das Getriebe 16 aber durch den Gummiring 42 gemildert wird. Bereits während der Schwenkbewegung in Aufstellrichtung hatte sich der Anschlag 48 an der Gewindespindel 18 gegen die Zwischenwand 32 gelegt. Durch den Aufprall des Absperrelements 12 auf den Trägerholm 50 kommt es zur axialen Verspannung des Antriebsstrangs zwischen dem Anschlag 48 am hinteren Ende und den Gelenkzapfen 66 am vorderen Ende. Da das Schraubgetriebe 18, 20 keine oder nur eine geringe Selbsthemmung hat, sind die Gewinde der Spindel 18 und der Buchse 20, 22 nicht stark verklemmt, sondern es besteht sogar die Tendenz, daß die nach hinten, also mit Bezug auf Fig. 5 nach links, drückende Gewindebuchse 20, 22 die Gewindespindel 18 in Rückwärtsrichtung in Drehung versetzt. Um diesen Vorgang auszulösen, genügt dann das verhältnismäßig kleine, aber durch das Getriebe 16 vervielfachte Drehmoment des kleinen Antriebsmotors 14. Er zieht zunächst die Gelenkzapfen 68 gegen die hinteren Enden der Langlöcher 70 und nimmt erst dann über die Koppeln 24 das Absperrelement 12 mit. Als Folge der Zugbelastung im Antriebsstrang verschiebt sich die Gewindespindel 18 ein wenig nach vorne, d. h. mit Bezug auf Fig. 5 und 6 nach rechts, so daß der andere fest mit der Gewindespindel 18.verbundene Anschlag 46 zur Anlage an der Zwischenwand 32 kommt. Nach Erreichen der flach liegenden Endstellung verhindert der Anschlag 46, daß das Absperrelement 12 mit äußerer Kraft nach oben gezogen werden kann.When the shut-off element is pivoted by extending the threaded bushing 20, 22 from the flat position shown in FIG. 6 in the erected locking position of FIG. 5, press the bearing pin 68 against the front end of the slots 70 of the coupling 24. At the end of this raising movement abuts the basic element 56, 60, which has stood upright in the starting situation according to FIG. 6, after a pivoting movement of z. B. 70 or 75 ° with the front edge of the crosspiece 60 against the top of the support beam 50, which thus forms a mechanical stop for limiting the pivoting movement when erecting. The engine control is designed so that the greater current consumption when abutting against an end stop or an obstacle to shut down the engine leads. The hard impact generates a torque impact, whose reaction to the gear 16 is mitigated by the rubber ring 42. Already during the pivoting movement in the erection direction, the stop 48 had been placed on the threaded spindle 18 against the intermediate wall 32. The impact of the shut-off element 12 on the carrier spar 50 causes the axial tension of the drive train between the stop 48 at the rear end and the pivot pin 66 at the front end. Since the helical gear 18, 20 has no or only a slight self-locking, the threads of the spindle 18 and the sleeve 20, 22 are not strongly jammed, but there is even a tendency that the rear, ie with reference to FIG left, pressing threaded bush 20, 22, the threaded spindle 18 is rotated in the reverse direction in rotation. To trigger this process, then satisfies the relatively small, but multiplied by the transmission 16 torque of the small drive motor 14. He first pulls the pivot pin 68 against the rear ends of the slots 70 and only then takes over the coupling 24 with the shut-12. As a result of the tensile load in the drive train, the threaded spindle 18 moves a little forward, ie, with reference to FIGS. 5 and 6 to the right, so that the other firmly connected to the threaded spindle 18.button 46 comes to rest on the intermediate wall 32. After reaching the flat lying end position prevents the stopper 46 that the shut-off element 12 can be pulled upwards with external force.

Es sei angenommen, daß kurz vor Erreichen der flach liegenden Endstellung nach Fig. 6 ein Hindernis, wie z. B. ein Stein, ein Ast oder Eis, die restliche Schwenkbewegung des Absperrelements 12 blockiert. Wenn statt der Langlöcher 70 zu den Gelenkzapfen 68 passende Rundlöcher vorhanden wären und der Antriebsstrang auch sonst kein axiales Spiel hätte, müßte er, nachdem sich der Antriebsmotor ausgeschaltet hat und das Rad eines Fahrzeugs über das Absperrelement 12 rollt, beim Nachgeben des blockierenden Hindernisses eine sehr große Belastung aufnehmen, die zur Beschädigung führen könnte. Da jedoch mit den Langlöchern 70 oder an anderer Stelle des Antriebsstrangs ein axiales Spiel vorhanden ist, kann beim Nachgeben des blockierenden Hindernisses unter der Wucht des darüber rollenden Rades das Absperrelement 12 um einen Winkel von z. B. 5° in die Endstellung nach Fig. 6 verschwenken, in der es eine feste Abstützung am Boden und/oder Gehäuse hat.It is assumed that shortly before reaching the flat-lying end position of FIG. 6, an obstacle, such. As a stone, a branch or ice, the remaining pivotal movement of the shutoff 12 blocks. If instead of the slots 70 to the pivot pin 68 matching round holes would be present and the drive train otherwise would have no axial play, he would after the drive motor has turned off and the wheel of a vehicle rolls over the shut-12, when yielding the blocking obstacle a very high load that could lead to damage. However, since with the slots 70 or elsewhere in the drive train, an axial clearance is present, the yielding of the blocking obstacle under the force of the wheel rolling over the shut-off element 12 by an angle of z. B. 5 ° in the end position of Fig. 6 pivot in which it has a solid support on the floor and / or housing.

Selbst nach einem solchen Vorfall läßt sich das Absperrelement 12 mit äußerer Kraft nur begrenzt nach oben ziehen.Even after such an incident, the shut-off element 12 can only be pulled upwards to a limited extent with external force.

Es versteht sich, daß die Einzelteile der beschriebenen Vorrichtung andere Formen haben können, sofern auch damit die erwähnten Funktionen gewährleistet sind. So kann z.B. der durch den Deckel 38 überdeckte, höhere Teil des Gehäuses etwa so weit nach vorne reichen, wie bei dem Ausführungsbeispiel der Trägerholm 50, und der gezeigte Antriebsstrang oder ein am hinteren Ende verschwenkbar gelagertes Schraubgetriebe und Schubgestänge 18, 22 im Gehäuseinnerern gelenkig an einem radialen Vorsprung eines im Durchmesser wesentlich größer als der Bolzen 54 bemessenen Lagerbolzens angreifen, der seitlich außerhalb des Gehäuses mit dem Absperrelement 12 verschweißt ist. Diese Konstruktion bietet den Vorteil, daß der Endanschlag für die Aufrichtbewegung des Absperrelements 12, gegen den z.B. der genannte radiale Vorsprung des Lagerbolzens stößt, im Inneren des Gehäuses angeordnet sein kann, so daß an dem Endanschlag keine Klemmgefahr besteht. Alternativ könnte wenigstens eine Endstellung auch dadurch bestimmt sein, daß ein Teil des Antriebsstrangs, z.B. die Gewindebuchse 20, 22 gegen einen Anschlag, z.B. ein Gehäuseteil, stößt. Schließlich besteht die Möglichkeit, den Antriebsmotor jeweils spätestens nach einer bestimmten Zeitdauer abzuschalten.It is understood that the items of the device described may have other forms, provided that the aforementioned functions are guaranteed. Thus, e.g. the covered by the lid 38, higher part of the housing about as far forward, as in the embodiment of the carrier spar 50, and the drive train shown or pivotally mounted at the rear end and helical gear rod 18, 22 in the housing interior hinged to a radial projection a bearing in the diameter substantially larger than the bolt 54 bearing bearing bolt attack, which is welded laterally outside of the housing with the shut-12. This construction offers the advantage that the end stop for the raising movement of the shut-off element 12 against which e.g. said radial projection of the bearing pin abuts, may be arranged in the interior of the housing, so that there is no risk of trapping at the end stop. Alternatively, at least one end position could also be determined by having a part of the drive train, e.g. the threaded bushing 20, 22 against a stop, e.g. a housing part, butts. Finally, it is possible to switch off the drive motor at the latest after a certain period of time.

Bei einer anderen abgewandelten Ausführungsform erstreckt sich das Schub- und Zuggestänge auf einem Niveau unterhalb der Schwenkachse 26 des Absperrelements 12, die in diesem Fall im oberen vorderen Bereich des Gehäuses gelagert ist.In another modified embodiment, the push and pull linkage extends at a level below the pivot axis 26 of the shut-off element 12, which is mounted in this case in the upper front region of the housing.
