Abstract

The post comprises a foot (2) anchored in the ground, and a shaft (1), connected to it via a joint (6). The shaft is folded down into an aperture in the ground, against a return spring (3), which is pretensioned to retain the upright shaft with a torque against a stop. The torque corresponds to at least 20% of the torque, which is applied in the opposite direction by the weight of the shaft when it is folded down. The spring is a gas pressure spring, and is positioned, so that during folding-down of the shaft, the effective contact lever of the spring extends through a maximum.

Description

Die vorliegende Erfindung betrifft einen Absperrpfosten mit einem im Boden zu verankernden Fuß und einem aufrichtbaren Schaft, der über ein Gelenk mit dem Fuß verbunden ist, wobei der Schaft gegen die Kraft einer Rückstellfeder in eine flache, an den Boden gedrückte Position oder alternativ in eine Bodenaussparung umlegbar ist.The present invention relates to a barrier post with a foot to be anchored in the ground and an erectable shaft which is connected to the foot via a joint, the shaft against the force of a return spring in a flat, pressed position on the ground or alternatively in one Floor recess is foldable.

Ein solcher Absperrpfosten ist beispielsweise aus der DE 43 02 295 A1 bekannt. Dieser bekannte Absperrpfosten weist eine Rückholfeder auf, die über einen Seilzug mit einem Fußteil des Absperrpfostens verbunden ist, wobei das andere Ende des Seilzuges mit einer Druckplatte verbunden ist, die auf das Ende einer Schraubenfeder drückt bzw. über den Seilzug auf dieses Ende der Schraubenfeder gezogen wird. Durch Umlegen des Pfostens wickelt der Seilzug sich teilweise auf eine gewölbte Fläche am Fuß des Absperrpfostens auf, so daß der gerade Abschnitt des Seilzuges verkürzt und dadurch die Druckplatte auf das Ende der Schraubenfeder gezogen wird und diese dabei komprimiert. Hierdurch wird eine Rückstellkraft erzeugt, die ausreichend ist, um den in die Horizontale umgelegten Pfosten selbsttätig wieder aufzurichten. Um bei unterschiedlichen Pfosten eine ausreichende Rückstellkraft zum Ausrichten des Pfostens erreichen zu können, kann die Vorspannung der Feder durch Änderung der effektiven Seilzuglänge eingestellt werden.Such a barrier post is known for example from DE 43 02 295 A1. This well-known Barrier post has a return spring which is connected to a foot part of the barrier post via a cable is connected, the other end of the cable being connected to a pressure plate which presses on the end of a coil spring or on the cable pull on this end of the coil spring is pulled. By pulling the post over, the cable pulls partially onto an arched one Surface at the foot of the barrier post so that the straight section of the cable shortens and thereby pulling the pressure plate onto the end of the coil spring and compressing it. As a result, a restoring force is generated which is sufficient to move the horizontal one To erect the post automatically. To ensure sufficient restoring force for different posts To be able to align the post, the spring can be preloaded Change the effective cable length.

Ein Nachteil der meisten bekannten umklappbaren Absperrpfosten mit Rückstellfeder liegt jedoch darin, daß sie häufig eine relativ aufwendige Federmechanik aufweisen, die oftmals mehreren Federn, Hebeln und, wie im Falle der vorgenannten Druckschrift, aus Seilzügen bestehen. Der aus dem vorgenannten Dokument bekannte Absperrpfosten benötigt außerdem eine Arretierung für den umgeklappten Pfosten, weil ansonsten die Kraft der Rückstellfeder den Pfosten wieder in die aufrechte Stellung zurückschnellen lassen würde. Ebenso weist dieser Pfosten eine Arretierung für die vertikale Position auf, da die Feder den Pfosten ansonsten über die vertikale Position hinaus in eine zur Umklapprichtung entgegengesetzte Richtung neigen würde.A disadvantage of most known foldable bollards with a return spring is, however, that they often have a relatively complex spring mechanism, which often has several springs, Lever and, as in the case of the aforementioned publication, consist of cables. The one from the above Known barrier post also requires a lock for the folded Post, because otherwise the force of the return spring returns the post to the upright position would snap back. This post also has a lock for the vertical position otherwise the spring will move the post beyond the vertical position to the direction of the flip opposite direction would tend.

Gegenüber diesem Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Absperrpfosten mit den eingangs genannten Merkmalen zu schaffen, der ohne zusätzliche Hilfsmittel in seinen beiden Endpositionen sicher gehalten wird, also sich weder selbständig aufrichtet noch bei Erschütterungen oder einem Windstoß aus der aufrechten Stellung umkippt, und der eine möglichst einfache und preiswerte Umklapp- bzw. Rückstellmechanik aufweist.Compared to this prior art, the present invention is based on the object Barrier posts with the features mentioned above to create the without additional aids is held securely in its two end positions, i.e. neither straightens up independently nor at Shocks or a gust of wind topples from the upright position, and one if possible has simple and inexpensive flip or reset mechanism.

Diese Aufgabe wird dadurch gelöst, daß die Rückholfeder eine stark vorgespannte Feder ist, welche den aufgerichteten Schaft mit einem Drehmoment gegen einen Anschlag in der aufgerichteten Position hält, welches mindestens 20% des Drehmomentes entspricht, was vom Gewicht des Schaftes in der umgeklappten horizontalen Position in Gegenrichtung ausgeübt wird, und daß die Feder derart angeordnet ist, daß der effektive Angriffshebel der Feder während der Umklappbewegung des Schaftes aus der einen in die andere Endposition über ein Maximum verläuft.This object is achieved in that the return spring is a strongly biased spring, which the erected shaft with a torque against a stop in the erected position holds, which corresponds to at least 20% of the torque, which is the weight of the shaft in the folded horizontal position is exercised in the opposite direction, and that the spring is arranged in this way is that the effective engagement lever of the spring during the flip movement of the shaft one goes to a maximum in the other end position.

Unter "starker Vorspannung" der Feder wird dabei eine Vorspannung verstanden, die mindestens 30% besser noch 50% oder auch mehr als 2/3 der maximal verwendeten Federspannung entspricht. Konkret bedeutet dies, daß der aufgerichtete Pfosten durch die Feder mit einer hinreichenden Spannung in der aufgerichteten Position gehalten wird, da diese Spannung immerhin mindestens 20% des Drehmomentes erzeugt, welches durch das Gewicht des horizontal liegenden Pfostens in die Gegenrichtung ausgeübt wird. Dieses Drehmoment aufgrund des Pfostengewichtes entfällt selbstverständlich im aufgerichteten Zustand, so daß der Pfosten dementsprechend sicher aufrecht gehalten wird. "Strong preload" of the spring is understood to mean a preload that is at least 30% better still corresponds to 50% or more than 2/3 of the maximum spring tension used. Concrete this means that the erected post by the spring with sufficient tension is held in the upright position, since this tension is at least 20% of the Torque generated by the weight of the horizontal post in the opposite direction is exercised. Of course, this torque due to the weight of the post is eliminated in the erected state so that the post is held securely upright accordingly.

Weiterhin ändert sich die von der Feder ausgeübte Kraft beim Umklappen des Pfostens aufgrund der Vorspannung weniger stark als dies bei einer nicht vorgespannten Feder der Fall wäre. Darüberhinaus kann man noch durch entsprechende Anordnung der Feder und der Federangriffspunkte dafür sorgen, daß sich während des Umklappens der effektive Federangriffshebel ändert. Je nach Ausgestaltung erreicht man dabei schon allein durch die Federvorspannung oder aber durch diese Vorspannung in Verbindung mit der effektiven Längenänderung des Federangriffshebels, daß das von der Feder ausgeübte Rückstellmoment auf den horizontal umgeklappten Pfosten kleiner ist als das von dessen Gewicht ausgeübte Drehmoment, so daß der Pfosten auch in der umgeklappten Stellung sicher liegen bleibt, ohne daß hierfür zusätzliche Hilfsmittel wie Verriegelungen oder Sperrhaken erforderlich sind. Gleichzeitig sorgt jedoch die Rückstellkraft der Feder dafür, daß der Pfosten sich im Vergleich zu einem solchen, der nicht mit einer Rückstellfeder ausgestattet ist, relativ leicht anheben läßt. Furthermore, the force exerted by the spring changes when the post is folded over due to the Preload less than would be the case with a non-preloaded spring. Furthermore can be ensured by arranging the spring and the spring application points accordingly, that the effective spring engagement lever changes during folding. Depending on the design can be achieved by the spring preload alone or by this preload in Connection with the effective change in length of the spring engagement lever that that exerted by the spring The restoring moment on the horizontally folded post is smaller than that of its weight exerted torque so that the post is securely in the folded position remains without the need for additional aids such as locks or locking hooks. At the same time, however, the restoring force of the spring ensures that the post is compared to one those that are not equipped with a return spring can be lifted relatively easily.

Der innere Aufbau der Umklapp- bzw. Rückstellmechanik ist denkbar einfach, da man neben einem Fuß, einem entsprechenden Pfostenschaft und der gelenkigen Verbindung dieser beiden Teile lediglich noch eine entsprechend vorgespannte Feder benötigt, wobei es sich versteht, daß der Schaft und der Fuß derart gelenkig miteinander verbunden sind, daß ein Umklappen des Pfostens nur zu einer Seite hin möglich ist, während ein Umklappen zur anderen Seite und unter der Wirkung der vorgespannten Feder durch entsprechende Anschläge am Pfosten und/oder am Fuß verhindert wird.The internal structure of the flip-over or reset mechanism is very simple, as a foot, a corresponding post shaft and the articulated connection of these two Parts only need a corresponding preloaded spring, it being understood that the shaft and the foot are connected to each other in such an articulated manner that a folding of the Post is only possible to one side, while folding to the other side and under the effect of the preloaded spring by appropriate stops on the post and / or on Foot is prevented.

Gemäß einer Ausführungsform der Erfindung wird die Feder derart angeordnet, daß sich der effektive Federangriffshebel der Feder um nicht mehr als 50% ändert. Dabei sollte die sich mit dem Umklappwinkel ändernde, effektive Hebellänge beim Umklappen aus der aufgerichteten in die flach umgelegte Stellung des Schaftes und umgekehrt über ein Maximum verlaufen. Dies stellt sicher, daß die Hebeländerungen insgesamt beim Umklappen um 90° relativ gering sind.According to one embodiment of the invention, the spring is arranged such that the effective spring action lever of the spring changes by no more than 50%. The should deal with effective lever length changing the flip angle when flipping from the upright position the flattened position of the shaft and vice versa extend over a maximum. This poses sure that the overall lever changes when folding by 90 ° are relatively small.

Gemäß einer besonderen Ausführungsform der Erfindung kann jedoch auch vorgesehen werden, daß diese effektive Hebellänge einen Nulldurchgang aufweist, was konkret bedeutet, daß der Hebel bezüglich des Drehpunktes und der Angriffsrichtung der Feder seine Wirkrichtung ändert, das Drehmoment also in die entgegengesetzte Richtung wirkt. Bei einer solchen Ausgestaltung erreicht man, daß der umgeklappte Schaft zusätzlich zu seinem Gewicht noch durch die Kraft bzw. das Drehmoment der Feder auf den Boden gedrückt wird, so daß beim Anheben und wieder Aufrichten des Schaftes zusätzlich zu dem Gewicht des Pfostens auch noch die Kraft der Feder überwunden werden muß, die dann über einen Totpunkt läuft und anschließend das weitere Aufrichten des Pfostens unterstützt und diesen schließlich in die aufgerichtete Stellung drückt.According to a special embodiment of the invention, however, it can also be provided that that this effective lever length has a zero crossing, which specifically means that the Lever changes its direction of action with respect to the pivot point and the direction of engagement of the spring, the torque works in the opposite direction. With such an arrangement one achieves that the folded shaft in addition to its weight by the force or the torque of the spring is pressed onto the floor, so that when lifting and again Erecting the shaft in addition to the weight of the post also the force of the spring must be overcome, which then runs over a dead center and then the rest Raising the post supports and finally pushes it into the erected position.

Die verwendete Feder ist zweckmäßigerweise eine Druckfeder und besonders bevorzugt eine Gasdruckfeder. Gasdruckfedem haben von vornherein eine sehr große Vorspannung, so daß sich über den zur Verfügung stehenden Hub der Gasruckfeder hinweg die von der Feder ausgeübte Kraft kaum verändert. Typischerweise liegt die Vorspannung bei Gasdruckfedem, d.h. die Spannung in vollständig ausgefahrenem Zustand bei mehr als 90% der Maximalspannung, d.h. der im vollständig eingefahrenen Zustand von der Gasdruckfeder ausgeübten Kraft. Gasdruckfedern erfordern insofern von vornherein die gewünschte Vorspannungsbedingung. Aber auch Spiralfedern können entsprechend angeordnet und vorgespannt werden, so daß sich während des Umklappens des Pfostens die Gesamtspannung der Feder um maximal 70%, vorzugsweise um weniger als 50% oder auch weniger als 30% ändert.The spring used is expediently a compression spring and particularly preferably one Gas Spring. Gas pressure springs have a very large preload from the outset, so that over the available stroke of the gas pressure spring, the one exerted by the spring Power hardly changed. Typically the preload is gas pressure springs, i.e. the Tension when fully extended at more than 90% of the maximum tension, i.e. the force exerted by the gas pressure spring when fully retracted. Gas springs therefore require the desired preload condition from the outset. But spiral springs can also be arranged and preloaded accordingly, so that during the folding of the post, the total tension of the spring by a maximum of 70%, preferably changes by less than 50% or even less than 30%.

Darüberhinaus könnte der Absperrpfosten auch mit einer Torsions- oder Spiralfeder ausgestattet werden, wobei letztere ebenfalls relativ stark vorgespannt werden können, so daß auch bei solchen Federn über einen weiteren Verspannwinkel von 90°, der durch das Umklappen des Schaftes aus der aufgerichteten in die umgelegte Position auf die Feder aufgebracht wird, die Änderung der Federkraft nur relativ gering ist. Derartige Spiral- oder Torsionsfedem haben darüberhinaus die für manche Anwendungsfälle wünschenswerte Eigenschaft, daß sich der effektive Angriffshebel der Federkraft während des Verschwenkens des Schaftes gegenüber dem Fußteil des Absperrpfostens nicht verändert.In addition, the bollard could also be equipped with a torsion or spiral spring are, the latter can also be relatively strongly biased, so that also such springs over a further bracing angle of 90 °, which by folding the Shaft from the erected to the folded position is applied to the spring Change in spring force is only relatively small. Such spiral or torsion springs have moreover, the desirable property for some applications that the effective lever of the spring force during the pivoting of the shaft relative to the Foot part of the barrier post not changed.

Im Falle der Verwendung einer Druckfeder (Schraubenfeder oder Gasdruckfeder) ist eine Ausführungsform der Erfindung besonders bevorzugt, bei welcher die Angriffspunkte der Feder am Fuß bzw. an einem mit dem Fuß fest verbundenen Teil einerseits und am Schaft andererseits zusammen mit dem Schwenkpunkt bzw. der Schwenkachse des Schaftes ein spitzwinkeliges Dreieck aufspannen, dessen kurze Basisseite von der Verbindung der Schwenkachse zum Angriffspunkt der Feder am Fuß gebildet wird.In the case of using a compression spring (coil spring or gas pressure spring) is one Embodiment of the invention is particularly preferred, in which the points of engagement of the spring on the foot or on a part firmly connected to the foot on the one hand and on the shaft on the other together with the pivot point or the pivot axis of the shaft an acute angle Span the triangle, the short base side of which connects the swivel axis to the Point of application of the spring is formed on the foot.

Dies ergibt eine sehr kompakte und platzsparende Anordnung der Feder, wobei der effektive Angriffshebel der Feder gebildet wird durch die Höhe in diesem spitzwinkeligem Dreieck, gemessen von der Schwenkachse als einem der Eckpunkte des Dreiecks auf die gegenüberliegende Seite bzw. deren Verlängerung.This results in a very compact and space-saving arrangement of the spring, the effective one Attack lever of the spring is formed by the height in this acute-angled triangle, measured from the pivot axis as one of the corner points of the triangle to the opposite Page or its extension.

Dabei ist eine solche Anordnung bevorzugt, bei welcher die kurze Basisseite von der Schwenkachse aus und relativ zu einer die Schwenkachse enthaltenden, horizontalen Ebene in einem Bereich zwischen 30° aufwärts von dieser Ebene und 60° abwärts zu dieser Ebene erstreckt, und zwar in der Schwenkebene des Pfostens und zu der Seite hin, zu welcher der Schaft des Pfostens umgelegt wird. Bei einer solchen Ausführungsform muß die Feder nicht notwendigerweise stark vorgespannt sein. Es reicht gegebenfalls eine geringe Vorspannung aus, die den Pfosten in der aufgerichteten Stellung hält, wenn keine oder nur geringfügige Kräfte auf ihn einwirken. Ein zu starker Anstieg des rückstellenden Drehmomentes kann durch die passende Anordnung der Federangriffspunkte relativ zur Schwenkachse verhindert werden, durch welche der effektive Federangriffshebel eine mehr oder weniger starke Veränderung erfährt.Such an arrangement is preferred in which the short base side is from the pivot axis from and relative to a horizontal plane containing the pivot axis in one Extends between 30 ° upwards from this plane and 60 ° downwards to this plane, and namely in the pivoting plane of the post and to the side to which the shaft of the post is thrown. In such an embodiment, the spring does not necessarily have to be strong be biased. It may be sufficient to apply a small amount of pre-tension to the post in the holds upright position when no or only slight forces act on it. One too strong increase in the restoring torque can be arranged by the appropriate arrangement Spring engagement points are prevented relative to the pivot axis, through which the effective Spring attack lever undergoes a more or less strong change.

Dabei entspricht die Aufwärtsneigung der kurzen Basisseite einer Ausführungsform bei welcher der effektive Angriffshebel der Feder seine Wirkrichtung ändert, während die Abwärtsneigung der Basisseite bedeutet, daß der effektive Federhebel zwischen den beiden Werten, die er für seine beiden Endpositionen einnimmt, über ein Maximum verläuft. The upward slope corresponds to the short base side of one embodiment in which the effective attack lever of the spring changes its direction of action, while the downward inclination of the Base side means that the effective spring lever is between the two values it holds for its takes both end positions, runs over a maximum.

Zweckmäßigerweise ist der Schaft des Absperrpfostens als Rohr ausgebildet. Dies dient nicht nur der Material- und Gewichtsersparnis bei guter Stabilität, sondern ermöglicht außerdem die Aufnahme wesentlicher Teile innerhalb des Schaftes. So ist z.B. in der bevorzugten Ausführungsform der Erfindung ein Abschnitt des Fußes in dem Schaft aufgenommen. Die Feder sollte vorzugsweise vollständig in dem Schaft bzw. Rohr aufgenommen sein. Dabei ist die Feder in der bevorzugten Ausführungsform der Erfindung zusammen mit einem Abschnitt des Fußes derart in dem als Rohr ausgebildeten Schaft aufgenommen, daß ihr eines Ende im Abstand von dem Gelenkpunkt bzw. der Schwenkachse am Fußteil und mit ihrem anderen Ende am Schaft, vorzugsweise in dessen Zentrum angreift, wobei der Abstand zwischen den beiden Federangriffspunkten gegenüber der kurzen Basisseite, die von dem Abstand des einen Angriffspunktes zur Schwenkachse gebildet wird, groß ist.The shaft of the barrier post is expediently designed as a tube. This doesn't just serve the material and weight savings with good stability, but also enables the Acquisition of essential parts within the shaft. For example, in the preferred embodiment the invention includes a portion of the foot in the shaft. The feather should preferably be completely received in the shaft or tube. The spring is in the preferred embodiment of the invention together with a portion of the foot so in the shaft designed as a tube added that its one end at a distance from the Pivot point or the pivot axis on the foot part and with its other end on the shaft, preferably attacks in the center thereof, the distance between the two spring engagement points compared to the short base side, which is from the distance of one point of attack to the Swivel axis is formed, is large.

Man erkennt in Figur 1 einen Schaft 1 in Form eines Rohres, welcher über ein Gelenk 6, 7 mit einem Fuß 2 verbunden ist. Einzelheiten des Fußes 2 werden im Zusammenhang mit Figur 2 beschrieben.One can see in FIG. 1 a shaft 1 in the form of a tube, which also has a joint 6, 7 a foot 2 is connected. Details of foot 2 are shown in connection with FIG. 2 described.

Ein Teil des Fußes 2 erstreckt sich in das untere Ende des Schaftes 1 hinein und ist dort an einem unteren Federangriffspunkt 5 mit einer hier nur schematisch dargestellten Druckfeder 3, die vorzugsweise eine Gasdruckfeder ist, verbunden. Das andere Ende der Gasdruckfeder 3 ist mit einem oberen Federangriffspunkt, z.B. einem sich quer durch das Zentrum des Schaftes 1 erstreckenden Stift, verbunden. Vorzugsweise sind die oberen und unteren Federangriffspunkte 4, 5 so ausgestaltet, daß die dort angreifende Feder 3 sich bezüglich der Angriffspunkte drehen kann. Die Federenden können also jeweils mit einer Öse versehen sein, die einen sich quer erstreckenden Stift oder eine Achse einerseits am Fuß 2 und andererseits im Schaft 1 umgreift. A part of the foot 2 extends into the lower end of the shaft 1 and is there a lower spring engagement point 5 with a compression spring 3 shown only schematically here is preferably a gas pressure spring connected. The other end of the gas pressure spring 3 is with an upper spring application point, e.g. one across the center of the shaft 1 extending pin connected. The upper and lower spring engagement points are preferred 4, 5 designed so that the spring 3 acting there rotate with respect to the points of attack can. The spring ends can thus each be provided with an eyelet that crosses one another extending pin or an axis engages on the one hand on the foot 2 and on the other hand in the shaft 1.

Der Schaft 1 ist um das Gelenk 6, 7 umklappbar und zwar in der Darstellung gemäß Figur 1 ausschließlich nach rechts, bis er flach auf dem Boden aufliegt. Die Gasdruckfeder 3 hält den Schaft 1 jedoch in der in Figur 1 dargestellten, aufrechten Position, solange keine Kräfte auf den Schaft 1 einwirken, welche die Rückstellkraft der Feder 3 überwinden.The shaft 1 can be folded over the joint 6, 7, specifically in the illustration according to FIG. 1 only to the right until it lies flat on the floor. The gas spring 3 holds the However, shaft 1 in the upright position shown in Figure 1, as long as no forces on the Act on shaft 1, which overcome the restoring force of spring 3.

Zusätzlich dargestellt ist in Figur 1 noch ein Schloßmechanismus, der insgesamt aus den Teilen 8 bis 15 besteht. Im einzelnen besteht dieser Schloßmechanismus aus einem Verriegelungsbolzen 11, einer Feder 10, einem U-förmigen Winkelstück 8, einem Stahlseil 12 und einem Zylinderschloß 13 mit einer Gegenhalterung und einem Betätigungselement 14, 15 für das Stahlseil. Mit Hilfe des Zylinderschlosses und der passend ausgestalteten Gegenhalterung und Seilbefestigung 14, 15 kann das Stahlseil 12 nach oben gezogen werden, wobei der am unteren Ende des Stahlseiles 12 befestigte Verriegelungsbolzen 11 gegen die Kraft der Feder 10 nach oben aus einer Verriegelungsöffnung herausgezogen wird. Die Druckfeder 10 sorgt in Verbindung mit dem als Gegenhalter dienenden Blechwinkel 8 dafür, daß der Bolzen 11 in Richtung der Verriegelungsöffnung vorgespannt ist. Die Verriegelung verhindert das Umklappen des Absperrpfostens, wenn sie bei aufrechtem Zustand des Schaftes 1 in Eingriff ist. Nach dem Lösen der Verriegelungsvorrichtung kann der Schaft 1 gegen die Kraft der Feder 3 verschwenkt werden.In addition, a lock mechanism is shown in Figure 1, which consists entirely of the parts 8 to 15 exists. In detail, this lock mechanism consists of a locking bolt 11, a spring 10, a U-shaped angle piece 8, a steel cable 12 and a cylinder lock 13 with a counter bracket and an actuating element 14, 15 for the steel cable. With the help of Cylinder lock and the appropriately designed counter bracket and cable attachment 14, 15 the steel cable 12 can be pulled upwards, the one at the lower end of the steel cable 12 attached locking bolt 11 against the force of the spring 10 upwards from a Locking opening is pulled out. The compression spring 10 provides in connection with the Bracket serving plate bracket 8 that the bolt 11 in the direction of the locking opening is biased. The lock prevents the barrier post from folding when it is engages when the shaft 1 is upright. After releasing the locking device the shaft 1 can be pivoted against the force of the spring 3.

Wie man schon in Figur 1 erkennt, spannen die beiden Federangriffspunkte 4, 5 zusammen mit dem Gelenk 6, 7 ein spitzwinkeliges Dreieck auf, dessen eine lange Seite von der Gasdruckfeder 3 gebildet wird, welche die Angriffspunkte 4, 5 der Feder verbindet und dessen andere lange Seite von der Verbindung oberer Federangriffspunkt 4 - Gelenk 6, 7 gebildet wird, während die kurze Seite dieses spitzwinkeligen Dreiecks von der Verbindung Gelenk 6, 7 zum unteren Federangriffpunkt 5 am Fuß 2 gebildet wird.As can be seen in Figure 1, the two spring engagement points 4, 5 together with the joint 6, 7 on an acute triangle, one long side of the gas pressure spring 3 is formed, which connects the points of attack 4, 5 of the spring and its other long side is formed by the connection of the upper spring application point 4 - joint 6, 7, while the short Side of this acute-angled triangle from the connection joint 6, 7 to the lower spring application point 5 is formed at the foot 2.

Wie man sieht, liegt der untere Federangriffspunkt 5 tiefer als die Drehachse 7 des Achsbolzens 6, so daß sich die kurze Seite c des erwähnten Dreiecks unter ca. 30° abwärts von der Drehachse 7 aus erstreckt. Berücksichtigt man, daß der effektive Federangriffshebel gebildet wird durch das von dem Gelenk 6, 7 auf die von der Feder 3 gebildete Dreiecksseite gefällte Lot, so erkennt man, daß der effektive Federangriffshebel in der dargestellten Position etwa den Wert 1/2 x √3 x Imax hat, daß der Federangriffshebel seinen Maximalwert Imax
hat, wenn der Schaft 1 gegenüber der Vertikalen um etwa 30° geneigt ist und daß der Federangriffshebel schließlich noch die Hälfte seines Maximalwertes hat, wenn der Schaft 1 flach auf dem Boden liegt. Für die angegebenen Zahlenverhältnisse ist vorausgesetzt, daß sich die erwähnte Dreiecksseite c von Gelenk 6, 7 aus unter einem Winkel von 30° gegenüber der Horizontalen abwärts erstreckt. As can be seen, the lower spring engagement point 5 is lower than the axis of rotation 7 of the axle pin 6, so that the short side c of the triangle mentioned extends below the axis of rotation 7 at approximately 30 °. If one takes into account that the effective spring engagement lever is formed by the plumb line fell from the joint 6, 7 onto the triangular side formed by the spring 3, it can be seen that the effective spring engagement lever in the position shown is approximately 1/2 x √3 x I max has that the spring action lever reaches its maximum value I max
has when the shaft 1 is inclined by about 30 ° with respect to the vertical and that the spring engagement lever finally still has half of its maximum value when the shaft 1 lies flat on the floor. For the given numerical ratios, it is assumed that the triangular side c mentioned extends downwards from joint 6, 7 at an angle of 30 ° with respect to the horizontal.

In Figur 3 ist die kurze Dreiecksseite c eingezeichnet und der effektive Federhebef l1 in der aufgerichteten Position des Schaftes 1 sowie der effektive Federhebel l2 in der flach umgelegten Position des Schaftes 1 sind mit gestrichelten Linien wiedergegeben, wobei die Beziehung gilt: I1 = 1/2 √3 x c; I2 = 1/2 c und Imax = c The short triangle side c is shown in FIG. 3 and the effective spring lever l 1 in the erected position of the shaft 1 and the effective spring lever l 2 in the flat folded position of the shaft 1 are shown with dashed lines, the relationship being: I 1 = 1/2 √3 xc; I 2 = 1/2 c and I Max = c

In Figur 2 ist der Fuß 2 im Detail zusammen mit dem gestrichelt eingezeichneten Schaft 1 dargestellt, so daß man die Wirkungsweise des Umklappmechanismus verstehen kann. Das Fußteil 2 besteht aus einer Grundplatte 21 mit Befestigungsbohrungen 29 und kann so mit Hilfe von Gewindebolzen im Boden verankert werden. Auf die Grundplatte 21 aufgeschweißt sind zwei sich im wesentlichen vertikal erstreckende Halteplatten 22, die einen lichten Abstand zwischeneinander haben, in welchem der Schaft 1, der hier als Rohr mit quadratischem Querschnitt ausgebildet ist, aufgenommen werden kann. Die beiden im Abstand voneinander angeordneten vertikalen Halteplatten 2 weisen zwei miteinander fluchtende Bohrungen auf, in welchen ein Achsbolzen 6 gelagert ist. Dieser Achsbolzen 6 erstreckt sich gleichzeitig auch zentral durch zwei gegenüberliegende Wände des Schaftes 1. Der Achsbolzen 6 ist entweder in den Bohrungen der vertikalen Platten 22 oder aber in den entsprechenden Bohrungen der gegenüberliegenden Wände des Schaftes 1 drehbar aufgenommen.In FIG. 2, the foot 2 is in detail together with the shaft 1 shown in dashed lines shown so that you can understand the operation of the flip mechanism. The Foot part 2 consists of a base plate 21 with mounting bores 29 and can thus with the help be anchored in the ground by threaded bolts. Two are welded onto the base plate 21 substantially vertically extending support plates 22 which are a clear distance between each other have in which the shaft 1, here as a tube with a square cross-section is trained, can be included. The two are spaced apart vertical holding plates 2 have two mutually aligned bores, in which one Axle pin 6 is mounted. This axle pin 6 extends simultaneously through two centrally opposite walls of the shaft 1. The axle pin 6 is either in the holes of the vertical plates 22 or in the corresponding holes in the opposite walls of the shaft 1 rotatably added.

In der Mitte zwischen den beiden vertikalen Platten 22 ist noch ein L-förmiges Befestigungsteil 23 angeordnet, dessen einer L-Schenkel 27 mit seinem freien Ende an der Grundplatte 31 befestigt, vorzugsweise angeschweißt ist. Der andere L-Schenkel 28 erstreckt sich im Abstand zu der Grundplatte 21 und im wesentlichen parallel zu dieser und in das untere Ende des rohrförmigen Schaftes 1 hinein. Am freien Ende dieses zweiten L-Schenkels befindet sich der Federangriffspunkt 5, der ebenfalls als gelenkige Verbindung ausgebildet ist, in dem eine (nicht dargestellte) Öse an einem Ende der Feder 3 in den vertikalen Schlitz 26 am freien Ende des erwähnten L-Schenkels 28 eingeführt wird, woraufhin ein Stift durch Bohrungen in dem freien Ende des zweiten L-Schenkels 28 hindurchgesteckt wird, und dabei den Schlitz 26 und die Öse am Ende der Feder 3 durchgreift. Das andere Ende der Feder 3 ist vorzugsweise ähnlich ausgebildet und an einem Querstift weiter oben Im Schaft 1 an dem in Figur 1 erkennbaren Angriffspunkt 4 drehbar befestigt. Im oberen Teil der Figur 2 erkennt man den Schaft 1 in aufgerichtetem Zustand, wobei der linke untere Rand des Schaftes 1 auf einem ausgesparten Abschnitt im Verbindungsbereich der beiden L-Schenkel aufsitzt. Konkret bedeutet dies, daß der Schaft 1 um die Drehachse 7 bzw. den Achsbolzen 6 nicht weiter nach links verschwenkt werden kann. Auf der rechten Seite ist dagegen der untere Rand des rohrförmigen Schaftes 1 jenseits des freien Endes des zweiten L-Schenkels 28 frei, so daß der Schaft 1 nach rechts verschwenkt werden kann, wobei der untere rechte Rand des Schaftes 1 nach unten um das freie Ende des zweiten L-Schenkels 28 herum geführt wird und in den Freiraum zwischen diesem L-Schenkel 28 und der Grundplatte 21 eingreift, wenn der Schaft 1 vollständig umgeklappt ist.In the middle between the two vertical plates 22 is an L-shaped fastening part 23 arranged, one L-leg 27 fastened with its free end to the base plate 31, is preferably welded. The other L-leg 28 extends at a distance from the Base plate 21 and substantially parallel to this and in the lower end of the tubular Shaft 1 into it. The spring application point is located at the free end of this second L-leg 5, which is also designed as an articulated connection, in which a (not shown) Eyelet at one end of the spring 3 in the vertical slot 26 at the free end of the mentioned L-leg 28 is inserted, whereupon a pin through holes in the free end of the second L-leg 28 is inserted, and thereby the slot 26 and the eyelet at the end of the spring 3 reaches through. The other end of the spring 3 is preferably of similar design and on one Cross pin further rotatably fastened in the shaft 1 at the point of attack 4 which can be seen in FIG. In the upper part of FIG. 2, the shaft 1 can be seen in the erected state, the left one lower edge of the shaft 1 on a recessed section in the connection area of the two L-leg sits on. Specifically, this means that the shaft 1 about the axis of rotation 7 or Axle pin 6 can not be pivoted further to the left. On the right is against the lower edge of the tubular shaft 1 beyond the free end of the second L-leg 28 free, so that the shaft 1 can be pivoted to the right, the lower right edge of the shaft 1 is guided down around the free end of the second L-leg 28 and engages in the space between this L-leg 28 and the base plate 21 when the Shaft 1 is completely folded down.

Außer der Anschlagaussparung für den linken unteren Schaftrand sind im Verbindungsbereich der beiden L-Schenkel 27, 28 noch eine Verriegelungsöffnung 25 und ein diese Verriegelungsöffnung 25 auf einer Seite begrenzende Steg 24 vorgesehen. In diese Verriegelungsöffnung 25 greift der im Zusammenhang mit Figur 1 beschriebene Verriegelungsbolzen 11 ein, um ein Verschwenken des Schaftes 1 aus seiner aufrechten Stellung zu verhindern, wenn der Verriegelungsbolzen nicht mit Hilfe des Zylinderschlosses 13 aus der Verriegelungsöffnung 25 herausgezogen wird.In addition to the stop cut-out for the lower left shaft edge, the two L-legs 27, 28 also a locking opening 25 and a locking opening 25 web 24 delimiting on one side is provided. In this locking opening 25 engages described in connection with Figure 1 locking bolt 11 to pivot to prevent the shaft 1 from its upright position when the locking bolt is not is pulled out of the locking opening 25 with the aid of the cylinder lock 13.

In Figur 4 erkennt man nochmals einen Absperrpfosten gemäß der Erfindung im Längsschnitt. Diese Ausführungsform ist mit der in Figur 1 mehr schematisch dargestellten Ausführungsform weitgehend identisch, zeigt jedoch die einzelnen Bauteile deutlicher in ihren tatsächlichen Konturen. Man erkennt auch hier ein Fußteil 2 und einen damit über den Bolzen 6 gelenkig verbundenen Schaft 1, der aus einem Rohr besteht, dessen oberes Ende durch eine Kappe 19 abgedeckt ist. In dem Schaft 1 ist etwas unterhalb der Kappe 19 ein Schloß 13 montiert, von welchem aus über ein Stahlseil 12 ein Bolzen 11 betätigt werden kann, der in eine Verriegelungsbohrung 25' am Fußteil 2 eingreift. Ein U-förmiger Bügel 8 mit zwei miteinander fluchtenden Bohrungen in den beiden U-Schenkeln nimmt den Bolzen 11 und dessen obere Verlängerung 11' in diesen Bohrungen auf, wobei die obere Verlängerung 11' mit dem Stahlseil 12 verbunden ist. Zwischen den U-Schenkeln des Bügels 8 ist eine Feder angeordnet, welche den Bolzen 11 bzw. dessen Verlängerung 11' umgreift und die sich mit ihrem oberen Ende an der Innenseite des Bügels 8 abstützt und mit ihrem unteren Ende an dem Bolzen 11 abstützt. Auf diese Weise wird der Bolzen 11 in die Bohrung 25' hinein vorgespannt, kann jedoch gegen die Kraft der Feder 10 über das Stahlseil 12 durch Betätigung des Schlosses 13 aus dieser Verriegelung herausgezogen werden.In Figure 4 you can see again a bollard according to the invention in longitudinal section. This embodiment is with the embodiment shown more schematically in FIG largely identical, but shows the individual components more clearly in their actual Contours. A foot part 2 can also be seen here and thus articulated via the pin 6 connected shaft 1, which consists of a tube, the upper end through a cap 19th is covered. In the shaft 1, a lock 13 is mounted slightly below the cap 19, by which can be operated from a steel cable 12, a bolt 11 which is in a locking hole 25 'engages the foot part 2. A U-shaped bracket 8 with two aligned Bores in the two U-legs takes the bolt 11 and its upper extension 11 ' in these bores, the upper extension 11 'being connected to the steel cable 12. Between the U-legs of the bracket 8, a spring is arranged, which the bolt 11 or whose extension 11 'encompasses and with its upper end on the inside of the Support bracket 8 and supported with its lower end on the bolt 11. That way the bolt 11 is biased into the bore 25 ', but can counter the force of the spring 10 pulled out of this lock via the steel cable 12 by actuating the lock 13 become.

Das Fußteil 2 weist neben zwei Platten 22, zwischen denen der Schaft 1 aufgenommen ist und welche mit einer Bohrung im Schaft fluchtende Bohrungen für die Aufnahme des Gelenkbolzens 6 aufweisen, auch noch ein sich dazwischen erstreckendes L-förmiges Teil 23 auf. Die Einzelheiten des Fußteils 2 sind am besten in Figur 5 zu erkennen, wobei Figur 5a eine Draufsicht von oben, Figur 5b eine Seitenansicht quer zur Achse des Gelenkbolzens 6 und Figur 5c eine Ansicht in Richtung des Bolzens 6 zeigt. Der L-Schenkel 27 des L-förmigen Teiles 23 ist auf die Bodenplatte 21 des Fußteiles 2 aufgeschweißt. Der zweite L-Schenkel 28 erstreckt sich in horizontaler Richtung parallel zur Bodenplatte 21 und im Abstand zu dieser. Der hintere Eckbereich des L-förmigen Teiles 23 weist eine Aussparung auf, die eine Kante des Schaftes 1 aufnimmt und als Anschlag in der vertikalen Position des Schaftes 1 dient. Im Abstand zu dieser Aussparung ist in der Oberseite des L-Schenkels 28 noch die Bohrung 25' vorgesehen, die als Verriegelungsbohrung dient und im Gegensatz zu der Aussparung 25 in der Ausführungsform gemäß Figur 2 hier einen zylindrischen Querschnitt hat.The foot part 2 has two plates 22, between which the shaft 1 is received and which are aligned with a hole in the shaft for receiving the hinge pin 6 also have an L-shaped part 23 extending between them. The Details of the foot part 2 can best be seen in FIG. 5, FIG. 5a being a plan view from above, Figure 5b is a side view transverse to the axis of the hinge pin 6 and Figure 5c one View in the direction of the bolt 6 shows. The L-leg 27 of the L-shaped part 23 is on the Welded base plate 21 of the foot part 2. The second L-leg 28 extends in horizontal direction parallel to and at a distance from the base plate 21. Rear Corner region of the L-shaped part 23 has a cutout that has an edge of the shaft 1 picks up and serves as a stop in the vertical position of the shaft 1. At a distance from this Recess is provided in the top of the L-leg 28, the bore 25 ', which as Locking hole serves and in contrast to the recess 25 in the embodiment 2 here has a cylindrical cross section.

Der Bolzen 6 hat in dieser zweiten Ausführungsform ein abgewinkeltes Endstück 6', mit Hilfe dessen der Bolzen 6 leichter in die miteinander ausgerichteten Bohrungen des Schaftes 1 und der Wandteile 22 eingeführt und herausgezogen werden kann.In this second embodiment, the bolt 6 has an angled end piece 6 ', with the help whose the bolt 6 easier in the aligned holes of the shaft 1 and Wall parts 22 can be inserted and pulled out.

Das freie Ende des L-Schenkels 28 ist wiederum mit einem vertikal verlaufenden Schlitz 26 zur Aufnahme einer Befestigungsöse der Gasdruckfeder 3 vorgesehen. Die beiden Wandabschnitte beiderseits des Schlitzes 26 am freien Ende des L-Schenkels 28 weisen zwei miteinander fluchtende Bohrungen 17, 18 auf, von denen die Bohrung 17 als Gewindebohrung ausgebildet ist. Bei der Montage geht man zweckmäßigerweise so vor, daß zunächst das obere Ende der Gasdruckfeder 3 an dem Schwenkpunt 4, d.h. an einem sich durch den Schaft quer hindurch erstreckenden Stift oder Bolzen befestigt wird. Dies kann entweder in der Weise geschehen, daß auch an dieser Stelle der Schaft 1 zwei miteinander fluchtende Bohrungen hat, durch welche ein Querstift hinhurch gesteckt wird, der gleichzeitig auch eine obere Öse der Gasdruckfeder 3 durchgreift, oder aber ein entsprechender Querstift wird in dem Schaft 1 befestigt, z. B. eingeschweißt, und das obere Ende der Feder 3 wird mit einem in etwa U-förmigen Eingriffsteil versehen, welches den Querstift umgreift und eine gelenkige Verbindung mit diesem bildet. Da die Feder 3 ohnehin immer unter Druckspannung steht, kann sich dieser Eingriff nicht von selbst lösen. Bei umgelegtem Schaft 1 kann anschließend das untere Ende der Feder 3 an dem freien Ende des L-Schenkels 28 befestigt werden, indem eine entsprechende Öse am Ende der Feder 3 in den Schlitz 26 eingeschoben wird, so daß die Ösenöffnung mit den Bohrungen 17, 18 fluchtet und anschließend wird ein entsprechender Bolzen durch die Öffnung 18 und die Öse der Feder hindurchgesteckt und in die Gewindebohrung 17 eingeschraubt. Der im Schlitzbereich 26 liegende Schaft des Bolzens kann dabei glatt und ohne Gewinde vorgesehen werden.The free end of the L-leg 28 is in turn with a vertically extending slot 26 for Inclusion of a fastening eye of the gas pressure spring 3 is provided. The two wall sections both sides of the slot 26 at the free end of the L-leg 28 have two with each other aligned bores 17, 18, of which the bore 17 is designed as a threaded bore. When assembling it is best to proceed so that first the upper end of the Gas pressure spring 3 at the pivot point 4, i.e. on one across the shaft extending pin or bolt is attached. This can either be done in such a way that also at this point the shaft 1 has two aligned holes through which one Cross pin is inserted through, which also an upper eyelet of the gas pressure spring 3rd engages, or a corresponding cross pin is fastened in the shaft 1, for. B. welded, and the upper end of the spring 3 is with an approximately U-shaped engagement part provided, which engages around the cross pin and forms an articulated connection with it. There the spring 3 is always under pressure anyway, this intervention can not by itself to solve. When the shaft 1 is folded over, the lower end of the spring 3 can then be connected to the free one End of the L-leg 28 are attached by a corresponding eyelet at the end of the spring 3 is inserted into the slot 26 so that the eyelet opening is aligned with the bores 17, 18 and then a corresponding bolt through the opening 18 and the eyelet of the spring inserted and screwed into the threaded bore 17. The one in the slot area 26 The shaft of the bolt can be provided smooth and without thread.

Anschließend wird der umgeklappte Schaft 1 aufgerichtet und gegen die Kraft der Feder 3 nach unten auf das Fußteil bzw. mit der hinteren unteren Kante des Schaftes 1 in die Aussparung im hinteren Eckbereichs des L-förmigen Teils 23 gedrückt, so daß die für den Gelenkbolzen 6 vorgesehenen Öffnungen des Schaftes und der Wandteile 22 miteinander fluchten. Anschließend wird der Gelenkbolzen durch die miteinander fluchtenden Bohrungen hindurchgesteckt und der abgewinkelte Schenkel 6' wird gegebenenfalls noch an der Au ßenseite der entsprechenden Platte 22 gesichert. Auch der Bolzen 6 könnte selbstverständlich als Gewindebolzen bzw. mit einem Gewindeende versehen werden und in ein entsprechendes Gewinde der einen Platte 22 eingreifen. Die zentrale Achse 7 des Gelenkbolzens 6 liegt zweckmäßigerweise bei allen Ausführungsformen in einem vertikalen Abstand zur Bodenplatte 21 bzw. zum Erdboden odedr zum Grund einer Bodenaussparung, die in etwa dem Abstand dieser Achse 7 zur, in Figur 1 und 4 rechten, Außenwand des Schaftes 1 entspricht. Der umgeklappte Pfosten liegt dann genau horizontal und nicht auf- oder abwärts geneigt. Die Montage des Schlosses 13 und des übrigen Schloßmechanismus erfolgtzweckmäßigerweise vor der Verbindung des Schaftes mit dem Fußteil 2 und vor dem Aufsetzen der Kappe 19 auf den Schaft 1.Then the folded shaft 1 is erected and counter to the force of the spring 3 below on the foot part or with the rear lower edge of the shaft 1 in the recess in pressed rear corner region of the L-shaped part 23, so that for the hinge pin 6th provided openings of the shaft and the wall parts 22 are aligned. Subsequently the hinge pin is inserted through the aligned holes and the angled leg 6 'is optionally still on the outside of the corresponding plate 22 secured. The bolt 6 could of course be used as a threaded bolt or with a Thread end are provided and in a corresponding thread of a plate 22nd intervention. The central axis 7 of the hinge pin 6 is expediently in all Embodiments at a vertical distance from the base plate 21 or to the ground or odedr to the bottom of a floor recess, which is approximately the distance of this axis 7 to, in Figure 1 and 4 right, outer wall of the shaft 1 corresponds. The folded post is then exactly horizontal and not inclined up or down. The assembly of the lock 13 and the rest The lock mechanism is expediently carried out before the connection of the shaft to the foot part 2 and before the cap 19 is placed on the shaft 1.

Der erfindungsgemäße Absperrposten ist insgesamt sehr einfach aufgebaut und läßt sich kostengünstig herstellen und montieren. Er wird in seiner vertikalen Endposition, auch ohne den Eingriff des Verriegelungsbolzens 11, durch die Gasdruckfeder 3 sicher gehalten und er bleibt auch in der horizontalen, umgeklappten Position trotz des Gegendruckes der Gasdruckfeder 3 sicher liegen, weil der effektive Hebelweg der Gasdruckfeder 3 entsprechend kurz und die Druckkraft der Gasdruckfeder 3 bzw. deren Zunahme beim Umklappen des Schaftes 1 entsprechend gering ist, so daß sie das vom Gewicht des Schaftes 1 ausgeübte Drehmoment nicht aufheben, wobei sie jedoch das Anheben des Schaftes 1 aus der umgeklappten Stellung noch beträchtlich erleichtert.The barrier post according to the invention is very simple overall and can be inexpensive to manufacture and assemble. It will be in its vertical end position, even without the Engagement of the locking bolt 11, held securely by the gas pressure spring 3 and it remains also in the horizontal, folded position despite the counter pressure of the gas pressure spring 3 lie safely because the effective lever travel of the gas pressure spring 3 is correspondingly short and the Compressive force of the gas pressure spring 3 or its increase when the shaft 1 is folded down is correspondingly low so that it exerts the torque exerted by the weight of the shaft 1 do not pick up, however, lifting the shaft 1 from the folded position still considerably relieved.
