Description

Die Erfindung betrifft eine Wege- oder Durchfahrtsperre für Fahrzeuge, insbesondere zum Sperren von Ein- und Ausfahrten oder Engestellen, bestehend aus einem wenig­stens teilweise in einer Vertiefung des Weges oder der Straße anzuordnenden Gehäuse, einer darin gelagerten Schwenkachse mit darauf drehsicher gehaltenen zueinander parallel und im Abstand angeordneten Sperrzinken sowie in einer oberen Gehäuseabdeckung vorgesehenen Ausneh­mungen für die Aufnahme der Sperrzinken, welche in der Freigabestellung der Sperre bündig zu der Gehäu­seabdeckung verlaufen und sich in der hochgeschwenkten Sperrstellung auf einem gehäuseseitigen Widerlager abstützen.The invention relates to a road or passage barrier for vehicles, in particular for blocking entrances and exits or narrow passages, consisting of a housing to be arranged at least partially in a recess of the path or the road, a pivot axis mounted therein with rotationally held thereon parallel and in each other Spacer locking tines and recesses provided in an upper housing cover for receiving the locking tines, which are flush with the housing cover in the release position of the lock and are supported in the pivoted-up locking position on an abutment on the housing side.

Es sind Wege- oder Durchfahrtsperren vorgenannter Art bekannt (DE-OS 31 34 247), welche sich durch eine Sperrwirkung, insbesondere für schwere Fahrzeuge, eignen und deren Sperrzinken sich in der Sperrstellung auf einem in dem Gehäuse angeordneten ortsfesten Wider­lager abstützen. Das Widerlager wirkt dabei mit einer dem freien Ende der Zinken abgekehrten Anlagefläche der Sperrzinken zusammen. Die bekannte Ausführung der beschriebenen Sperre muß in der Praxis mit einem relativ robusten steuerbaren Antrieb, beispielsweise einem hydraulischen oder pneumatischen Arbeitsglied oder aber mit einem elektromotorischen Antrieb, aus­gerüstet werden, um die Sperrzinken von der einen in die andere Stellung überführen zu können. Um mit möglichst geringer Antriebsenergie auszukommen, ist es erforderlich, zwischen dem Antriebselement und der Schwenkachse ein relativ großes Übersetzungsgetriebe vorzusehen, wodurch die Bewegungsgeschwindigkeit der Sperrzinken entsprechend vermindert wird. Beim Ausfall des Antriebes bleiben die Sperrzinken in der jeweilig gerade eingenommenen Position und können praktisch nicht aus der Freigabestellung in die Sperrstellung überführt werden, wenn der Antrieb in der Freigabe­stellung der Sperre ausfallen sollte.Road or transit barriers of the aforementioned type are known (DE-OS 31 34 247), which are suitable due to a locking effect, in particular for heavy vehicles, and whose locking tines are in the locking position support on a fixed abutment arranged in the housing. The abutment cooperates with a contact surface of the locking tines facing away from the free end of the tines. The known embodiment of the lock described must be equipped in practice with a relatively robust controllable drive, for example a hydraulic or pneumatic working member or with an electric motor drive, in order to be able to transfer the locking tines from one position to the other. In order to get by with the lowest possible drive energy, it is necessary to provide a relatively large transmission gear between the drive element and the pivot axis, as a result of which the speed of movement of the locking tines is correspondingly reduced. If the drive fails, the locking tines remain in the position they have just assumed and can practically not be moved from the release position to the lock position if the drive should fail in the release position of the lock.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschriebene Wege- oder Durchfahrtsperre so weiter­zubilden, daß eine von einem Antriebsaggregat unab­hängige Überführung der Zinken von der einen in die andere Stellung ermöglicht wird, eine sehr kurzfristige Überführung der Zinken von der Freigabe- in die Sperr­stellung erreichbar ist und beim Ausfall der Ener­gieversorgung die Sperrzinken automatisch in die Sperr­stellung überführt werden.The invention has for its object to develop the way or passage barrier described above so that a transfer of the tines independent of a drive unit is made possible from one position to the other, a very short-term transfer of the tines from the release position into the blocking position can be achieved and if the power supply fails, the locking tines are automatically transferred to the locking position.

Zur Lösung vorstehender Aufgabe kennzeichnet sich die genannte Sperre erfindungsgemäß dadurch, daß inner­halb des Gehäuses wenigstens ein die Sperrzinken in der Freigabestellung der Sperre haltender Elektromagnet angeordnet und mindestens eine auf die Sperrzinken wirkende Feder vorgesehen ist, welche die Zinken gegen die Wirkung des Magneten in die Sperrstellung zu über­führen suchen.To solve the above problem, the said lock is characterized according to the invention in that at least one electromagnet holding the locking prongs in the release position of the lock and at least one on the locking prongs are arranged within the housing Acting spring is provided, which seek to transfer the tines against the action of the magnet in the locked position.

Bei der vorgenannten Ausgestaltung werden die Sperr­zinken bei entsprechender Erregung des bzw. der Elek­tromagnete in der Sperrstellung gegen die Wirkung der Feder bzw. der Federn gehalten und nehmen in dieser Position die Freigabestellung ein, in der die Sperre ohne Schwierigkeiten überfahren werden kann. Bei Ent­regung der Elektromagnete werden die Zinken durch die Einwirkung der Federn in Abhängigkeit von der Federkraft und der Federkennlinie mit relativ großer Bewegungsgeschwindigkeit in die Sperrstellung überführt und in dieser Stellung durch die Federn gehalten, wobei wie bei der bekannten Ausführung ein ortsfestes Widerlager für die Sperrzinken vorgesehen ist, auf denen sie sich in der Sperrstellung abstützen.In the aforementioned embodiment, the locking tines are held in the locked position against the action of the spring or springs when the electromagnet (s) are energized accordingly and assume the release position in this position, in which the lock can be passed without difficulty. When the electromagnets are de-energized, the tines are moved into the locking position by the action of the springs depending on the spring force and the spring characteristic with a relatively high speed of movement and held in this position by the springs, with a stationary abutment for the locking tines provided in the known embodiment on which they are based in the locked position.

Um die Zinken wieder in ihre Freigabestellung zu über­führen, können diese beispielsweise durch eine Bedie­nungsperson, und zwar durch Betätigung mit dem Fuß, in die Freigabestellung überführt werden, indem die Bedienungsperson gegen das freie Ende eines der auf der Schwenkachse drehsicher gehaltenen Zinkens drückt und die Zinken gegen die Wirkung der Federn in die Freigabestellung herunterdrückt, bis die Elekromagnete zur Wirkung kommen und die Sperrzinken mit Erreichen der Freigabestellung in dieser Stellung halten. Der Elektromagnet braucht somit für die Überführung der Zinken nur sehr kurzzeitig entregt zu werden und kann nach der Freigabe der Zinken bereits wieder mit dem Erregerstrom beaufschlagt werden, so daß er in dem Bereitschaftszustand überführt wird, um bei der Rück­führung der Zinken diese in der Freigabestellung zu halten.In order to move the tines back into their release position, they can be transferred into the release position by an operator, for example, by actuation with the foot, by pressing the operator against the free end of one of the tines held on the pivot axis and the tines press against the action of the springs in the release position until the electromagnets come into effect and hold the locking prongs in this position when the release position is reached. The electromagnet therefore only needs to be de-energized for a very short time for the transfer of the tines and can already be supplied with the excitation current again after the tines have been released, so that it is transferred to the ready state so that when the tines are returned they are in the release position hold.

Bei der beschriebenen Rückführung der Zinken durch die Bedienungsperson macht es sich günstig bemerkbar, daß die Feder zu Beginn der Rückbewegung nur mit relativ geringer Kraft auf die Zinken einwirkt und im Zuge der Rückbewegung der Zinken dann zunimmt. Hierdurch kann die Bedienungsperson im Laufe der Rückbewegung der Zinken vermehrt ihr Körpergewicht einsetzen, um hierdurch die zunehmende Federkraft zu überwinden.In the case of the described return of the tines by the operator, it is noticeably noticeable that the spring acts on the tines only with relatively little force at the beginning of the return movement and then increases in the course of the return movement of the tines. As a result, the operator can increasingly use his body weight in the course of the return movement of the tines in order to overcome the increasing spring force.

Zweckmäßig ist es, wenn der bzw. jeder Elektromagnet an einem gehäusefesten Teil gehalten und eine ihm zugeordnete Ankerplatte an einem mit der Schwenkachse drehsicher verbundenen in allen Stellungen im Gehäu­seinneren liegenden radialen Arm angeordnet ist. Hier­durch wird der mit der Erregerspule versehene Teil des Magneten ortsfest gehalten, so daß sich eine Verein­fachung der Installation und eine Verminderung der Störanfälligkeit ergibt. Durch die Anordnung der Anker­platte an einem radialen Arm kann in Abhängigkeit von dem Abstand der Platte vom Zentrum der Schwenk­achse die Haltekraft des Magneten und damit der Erreger­strom entsprechend kleiner gehalten werden. Hierdurch ergibt sich eine Verminderung des Aufwandes für die Elektromagnete.It is expedient if the or each electromagnet is held on a part fixed to the housing and an armature plate assigned to it is arranged on a radial arm which is connected to the pivot axis in a rotationally secure manner and is located in all positions inside the housing. As a result, the part of the magnet provided with the excitation coil is held stationary, so that the installation is simplified and the susceptibility to interference is reduced. By arranging the armature plate on a radial arm, the holding force of the magnet and thus the excitation current can be kept correspondingly smaller depending on the distance of the plate from the center of the pivot axis. This results in a reduction in the effort for the electromagnets.

Die oder jede Feder ist zweckmäßigerweise mit ihrem einen Ende an einem radial verlaufenden mit der Schwenk­achse drehsicher verbundenen Arm und anderendig an einem gehäusefesten Teil angreifend angeordnet. Bei entsprechender Winkelstellung des drehsicher mit der Schwenkachse verbundenen Armes in Bezug auf die Zinken kann zu Beginn der Schwenkbewegung der Zinken von der Freigabe- in die Sperrstellung die höchste Feder­kraft auf die Schwenkachse zur Einwirkung gebracht werden, so daß eine anfänglich sehr hohe Beschleunigung der Zinken erzielt wird, um diese möglichst kurzfristig in die Sperrstellung zu überführen. Dies ist von Bedeu­tung, wenn beispielsweise die Auslösung der Sperre, d.h. die Entregung des Magneten mittels einer der Sperre vorgeordneten Auslöseeinrichtung erfolgen soll. So ist es denkbar, der Sperre eine Schranke vorzuordnen und bei dem Versuch der gewaltsamen Überwindung der in Sperrstellung befindlichen Schranke durch entspre­chende von der Schranke betätigte Auslösemechanismen die Elektromagnete der Wege- oder Durchfahrtsperre zu entregen, so daß die Zinken automatisch durch die Federwirkung in die Sperrstellung überführt werden. Je kürzer die Zeitspanne für diese Überführung der Zinken in die Sperrstellung ist, umso dichter kann die Auslöseeinrichtung an die Sperre heranverlegt werden.The or each spring is expediently arranged with its one end engaging on a radially extending arm connected to the pivot axis in a rotationally secure manner and at the other end on a part fixed to the housing. With a corresponding angular position of the arm securely connected to the pivot axis with respect to the tines, the highest spring force can be brought into effect on the pivot axis at the beginning of the pivoting movement of the tines from the release position into the blocking position, so that an initially very high acceleration the tine is achieved in order to bring it into the blocking position as quickly as possible. This is important if, for example, the lock is to be released, ie the magnet is de-energized by means of a release device arranged upstream of the lock. So it is conceivable to place a barrier in front of the barrier and to de-energize the electromagnets of the road or transit barrier when attempting to forcefully overcome the barrier in the locked position by means of corresponding trigger mechanisms actuated by the barrier, so that the tines automatically move into the locked position by the spring action be transferred. The shorter the time span for this transfer of the tines to the locked position, the closer the triggering device can be moved to the lock.

Die beschriebene Ausführung der Sperre mit einer Betä­tigung durch Zurückdrücken der Zinken von der Sperr­stellung in die Freigabestellung durch eine Bedie­nungsperson ist verständlicherweise in ihren räumlichen Abmessungen relativ eng begrenzt und wird bestimmt durch die Federkräfte und die Reibungswiderstände, die beim Zurückdrücken der Zinken von der Bedienungs­person überwunden werden müssen. Um jedoch das be­schriebene Prinzip der Sperre auch bei größeren Ab­messungen beibehalten zu können, ist bei einer bevor­zugten Ausführungsform der Erfindung vorgesehen, daß zum Rückschwenken der Zinken von der Sperr- in die Freigabestellung der Sperre ein mit der Schwenkachse getrieblich kuppelbarer Antriebsmotor vorgesehen ist. Der Antriebsmotor kann dabei relativ klein gehalten und über ein entsprechendes Getriebe mit der Schwenk­achse kuppelbar sein, da er lediglich für Rückführung der Zinken in die Freigabestellung vorgesehen ist und dieser Bewegungsablauf im Gegensatz zur Überführung der Zinken in die Sperrstellung sehr langsam erfolgen kann.The described design of the lock with an actuation by pushing the tines back from the locked position into the release position by an operator is understandably relatively narrow in its spatial dimensions and is determined by the spring forces and the frictional resistances that are overcome by the operator when the tines are pushed back have to. However, in order to be able to maintain the described principle of the lock even with larger dimensions, it is provided in a preferred embodiment of the invention that a drive motor which can be coupled to the pivot axis is provided for pivoting the tines back from the locking position into the release position of the lock. The drive motor can be kept relatively small and can be coupled to the pivot axis via a corresponding gear, since it is only intended for returning the tines to the release position and in contrast to the transfer of the tines into the locked position, this sequence of movements can take place very slowly.

Statt eines Elektromotors kann auch ein hydraulisches oder pneumatisches Arbeitsglied verwendet werden, um auch hier mit geringen Kräften auskommen zu können.Instead of an electric motor, a hydraulic or pneumatic working element can also be used in order to be able to manage with low forces.

Besonders günstig ist es, wenn der kuppelbare Antriebs­motor innerhalb des Gehäuses geschützt untergebracht ist.It is particularly advantageous if the detachable drive motor is accommodated in a protected manner within the housing.

Die in den Figuren wiedergegebene Sperre weist ein insgesamt mit 1 bezeichnetes Gehäuse auf, welches bis zu der in Fig. 2 angedeuteten Höhe H in den Fahr­untergrund eingebaut wird. Die nach oben weisenden Gehäuseabdeckungen 1a und 2a bilden gegensinnig geneigt verlaufende Schrägflächen, so daß das in dem Fahrun­tergrund eingebaute Gehäuse wie eine relativ breite schwellenförmige Erhebung aussieht. Die Gehäuseab­ deckungen 1a und 2a sind fest an einem in Richtung der Mittellängsachse des Gehäuses 1 verlaufende Doppel-T-­Profil 3 befestigt, welches das tragende Element des gesamten Gehäuses 1 und der darin untergebrachten Bauteile bildet.The lock shown in the figures has a housing designated overall by 1, which is installed up to the height H indicated in FIG. 2 in the driving surface. The upward-facing housing covers 1a and 2a form inclined surfaces running in opposite directions, so that the housing installed in the driving surface looks like a relatively wide, threshold-shaped elevation. The housing Covers 1a and 2a are firmly attached to a double T-profile 3 running in the direction of the central longitudinal axis of the housing 1, which double-profile forms the supporting element of the entire housing 1 and the components accommodated therein.

In dem von der Gehäuseabdeckung 2a abgedeckten Teil des Gehäuses 1 ist in unmittelbarer Nähe des Doppel-T-­Profiles 3 eine in Längsrichtung dieses Profiles ver­laufende Schwenkachse 4 vorgesehen, die in gestrichelt in Fig. 1 angedeuteten Lagern 5 gehalten ist, die ihrerseits mit dem Doppel-T-Profil 3 verbunden sind. Auf der Schwenkachse 4 sind drehsicher im Abstand und parallel zueinander gehaltene Sperrzinken 6 an­geordnet, die nach Art einarmiger Hebel auf der Schwenk­achse 4 gehalten und in Richtung ihrer freien Enden verjüngt ausgebildet sind.In the part of the housing 1 covered by the housing cover 2a, a swivel axis 4 extending in the longitudinal direction of this profile is provided in the immediate vicinity of the double-T profile 3 and is held in bearings 5 indicated by dashed lines in FIG. 1, which in turn is with the double -T profile 3 are connected. On the pivot axis 4 are arranged in a rotationally spaced and parallel to each other locking tines 6 which are held in the manner of one-armed lever on the pivot axis 4 and are tapered in the direction of their free ends.

In der Gehäuseabdeckung 2a sind für die Sperrzinken 6 entsprechende Ausnehmungen 7 in Form von Schlitzen vorgesehen. Diese Schlitze werden in der eingeschwenkten Stellung der Zinken 6, also in der Freigabestellung, im wesentlichen von den Zinken 6 ausgefüllt.Corresponding recesses 7 in the form of slots are provided in the housing cover 2a for the locking tines 6. These slots are essentially filled by the tines 6 in the pivoted-in position of the tines 6, that is to say in the release position.

In der hochgeschwenkten Sperrstellung der Zinken 6 stützen diese sich gemäß der Darstellung in Fig. 2 mit einer Schulter 8 auf dem Doppel-T-Profil 3 ab, so daß das Doppel-T-Profil gleichzeitig das ortsfeste Widerlager für die Sperrzinken 6 in der Sperrstellung bildet.In the pivoted-up locking position of the tines 6, these are supported as shown in FIG. 2 with a shoulder 8 on the double-T profile 3, so that the double-T profile simultaneously the stationary abutment for the locking tines 6 in the locking position forms.

Innerhalb des von der Gehäuseabdeckung 2a abgedeckten Gehäusebereiches sind ferner an dem Doppel-T-Profil 3 in Längsrichtung dieses Profiles im Abstand ange­ordnete Elektromagnete 9 befestigt, welche mit Anker­ platten 10 zusammenwirken, die ihrerseits an jeweils einem mit der Schwenkachse 4 drehsicher verbundenen radialen Arm 11 befestigt sind. Über die Längserstreckung des Doppel-T-Profiles 3 können dabei je nach Länge dieses Profiles und damit nach Länge des Gehäuses mehrere derartige Elektromagnete vorgesehen sein, die jeweils mit diesen zugeordneten Ankerplatten 10 zusammenwirken.Within the housing area covered by the housing cover 2 a, electromagnets 9 are also fixed to the double-T profile 3 in the longitudinal direction of this profile and are spaced apart with an armature plates 10 cooperate, which in turn are each attached to a rotationally connected to the pivot axis 4 radial arm 11. Depending on the length of this profile and thus the length of the housing, several such electromagnets can be provided over the longitudinal extension of the double-T profile 3, each of which cooperates with the anchor plates 10 assigned to them.

In der Fig. 4 ist der Elektromagnet 9 mit der zugehö­rigen Ankerplatte 10 in der Schließstellung wieder­gegeben, in welcher die Sperrzinken 6 die Freigabe­stellung einnehmen. Die Stromversorgung des Elektro­magneten 9 erfolgt über eine elektrische Zuleitung, die in der Zeichnung nicht wiedergegeben ist. Es ist lediglich aus den Fig. 1 und 4 erkennbar, daß in einer Seitenwandung des Gehäuses 1 Durchführungsrohre 12 und 13 angeordnet sind, von denen das Rohr 13 als Zuführungsrohr für das elektrische Kabel und die Rohre 12 als Entwässerungsrohre dienen.4 shows the electromagnet 9 with the associated armature plate 10 in the closed position, in which the locking prongs 6 assume the release position. The electromagnet 9 is supplied with power via an electrical feed line, which is not shown in the drawing. It can only be seen from FIGS. 1 and 4 that feed-through tubes 12 and 13 are arranged in a side wall of the housing 1, of which the tube 13 serves as a feed tube for the electrical cable and the tubes 12 serve as drainage tubes.

In Längsrichtung der Schwenkachse 4 sind außer den radialen Armen 11 mit den daran angeordneten Anker­platten 10 an der Schwenkachse weitere drehsicher mit ihr verbundene Arme 14 vorgesehen, an denen jeweils eine Feder 15 angreift, die anderendig an einem gehäuse­festen Teil 17 befestigt ist, wie besonders deutlich aus Fig. 3 hervorgeht. Je nach Länge des Gehäuses in Richtung der Längserstreckung des Doppel-T-Profiles 3 sind mehrere parallel zueinander verlaufende Arme 14 und diesen zugeordnete Federn 15 vorgesehen.In the longitudinal direction of the pivot axis 4, in addition to the radial arms 11 with the anchor plates 10 arranged thereon, further arms 14 connected to it in a rotationally secure manner are provided, on each of which a spring 15 engages, which is otherwise attached to a part 17 fixed to the housing, as is particularly evident 3 emerges. Depending on the length of the housing in the direction of the longitudinal extent of the double-T profile 3, a plurality of arms 14 running parallel to one another and springs 15 associated therewith are provided.

In der eingeschwenkten Stellung der Zinken 6, also in der Freigabestellung gemäß Fig. 3, erstrecken sich die Arme 14 durch entsprechend vorgesehene Fenster im Mittelschenkel des Doppel-T-Profiles 3.In the pivoted-in position of the tines 6, that is to say in the release position according to FIG. 3, the arms 14 extend through correspondingly provided windows in the middle leg of the double-T profile 3.

In der Fig. 2 ist die Position der Arme 14 und der Federn 15 bei hochgeschwenkten Zinken 6, also in der Sperrstellung der Zinken, ersichtlich. Man erkennt, daß sowohl die Arme 14 als auch die Federn 15 ebenso wie die radialen Arme 11 und die darauf gehaltenen Ankerplatten 10 in allen Positionen der Zinken 6 inner­halb des Gehäuses 1 verbleiben und somit geschützt untergebracht sind.2 shows the position of the arms 14 and the springs 15 when the tines 6 are pivoted up, that is to say in the locked position of the tines. It can be seen that both the arms 14 and the springs 15 as well as the radial arms 11 and the anchor plates 10 held thereon remain in all positions of the tines 6 within the housing 1 and are therefore protected.

Während bei der Entregung der Elektromagneten 9 automa­tisch durch die Wirkung der Federn 15 die Sperrzinken 6 in die Sperrstellung mit hoher Geschwindigkeit ver­schenkt werden, erfolgt die Rückbewegung der Zinken 6 durch eine Bedienungsperson, indem diese beispiels­weise mit dem Fuß gegen das freie Ende eines der Sperr­zinken 6 drückt, um diesen nach unten hin zu verschwen­ken, wobei mit zunehmender Schwenkbewegung ein erhöhtes Körpergewicht der Bedienungsperson auf den Sperrzinken 6 zur Einwirkung gebracht werden kann. Der Elektromagnet 9 kann unmittelbar nach der erfolgten Freigabe der Sperrzinken 6 wieder erregt werden, so daß bei der Rückschwenkung der Zinken 6 die Ankerplatten 10 von dem Magneten angezogen werden und hierdurch die Frei­gabestellung der Sperrzinken gesichert wird.While when the electromagnets 9 are de-energized, the locking tines 6 are automatically given away into the locking position at high speed by the action of the springs 15, the tines 6 are moved back by an operator, for example by foot against the free end of one of the locking tines 6 presses in order to pivot it downwards, with an increasing body weight of the operator being able to act on the locking tines 6 with increasing pivoting movement. The electromagnet 9 can be excited again immediately after the release of the locking tines 6, so that when the tines 6 are pivoted back, the armature plates 10 are attracted by the magnet, thereby securing the release position of the locking tines.

Im Falle eines Stromausfalles verschwenken die Sperr­zinken automatisch in die Sperrstellung. Es kann die Sperre somit nicht durch mutwilliges Unterbrechen der Stromzuführung außer Wirkung gesetzt werden.In the event of a power failure, the locking tines automatically pivot into the locked position. The lock cannot therefore be deactivated by deliberately interrupting the power supply.

In den Fig. 1 und 2 ist strichpunktiert angedeutet, wie insbesondere bei großräumigen oder sehr massiven Sperren der dargestellten Art statt der Rückführung der Sperrzinken 6 in die Freigabestellung durch eine Bedienungsperson die Rückführung durch einen mit der Schwenkachse 4 kuppelbaren Antriebsmotor 18 erfolgen kann. Zu diesem Zweck ist das Gehäuse 1 gemäß Fig. 1 durch einen zusätzlichen Abschnitt 21 erweitert, da die Zwischenräume zwischen den einzelnen Sperr­zinken 6 durch die vorgesehenen radialen Arme 11 und 14 bzw. durch die Lager 15 weitgehend ausgefüllt sind und der Angriff eines Elektromotors zwischen den Sperr­zinken 6 praktisch nicht möglich ist. Der Elektromotor 18 ist in dem dargestellten Beispiel mit einem Unter­setzungsgetriebe 19 verbunden. Über einen Riemen- oder Kettentrieb 20 ist die Abtriebseite des Unter­setzungsgetriebes 19 mit der Schwenkachse 4 verbunden. Durch die Ausbildung des Elektromotors 18 als Anker­schubmotor oder aber durch Zwischenanordnung einer Kupplung muß sichergestellt werden, daß der Elektro­motor 18 die Sperrzinken nur zum Verschwenken von der Sperrstellung in die Freigabestellung antreibt, während die Rückbewegung der Zinken von der Freiga­bestellung in die Sperrstellung durch den Antrieb nicht behindert wird. Kupplungen dieser Art sind in verschiedener Ausführung bekannt. Die Verschwenkbewegung der Sperrzinken 6 von der Sperrstellung in die Frei­gabestellung kann relativ langsam erfolgen, so daß ein relativ kleiner und leistungsschwacher Antriebsmotor 18 genügt, der ohne Schwierigkeiten in dem Gehäuse 1 untergebracht werden kann.1 and 2 are indicated by dash-dotted lines, such as in particular in the case of large-scale or very massive barriers of the type shown instead of the return the locking tines 6 into the release position by an operator can be returned by a drive motor 18 which can be coupled to the pivot axis 4. For this purpose, the housing 1 according to FIG. 1 is expanded by an additional section 21, since the spaces between the individual locking tines 6 are largely filled by the radial arms 11 and 14 provided or by the bearings 15 and the attack of an electric motor between the Locking tines 6 is practically not possible. In the example shown, the electric motor 18 is connected to a reduction gear 19. The output side of the reduction gear 19 is connected to the pivot axis 4 via a belt or chain drive 20. By designing the electric motor 18 as an armature thrust motor or by arranging a clutch in between, it must be ensured that the electric motor 18 only drives the locking tines for pivoting from the locked position into the release position, while the return movement of the tines from the released position into the locked position by the drive does not is hindered. Couplings of this type are known in various designs. The pivoting movement of the locking tines 6 from the locking position into the release position can take place relatively slowly, so that a relatively small and underpowered drive motor 18 is sufficient, which can be accommodated in the housing 1 without difficulty.
