Description

Die Erfindung betrifft eine einstellbare Halterung für Pfosten nach dem Oberbegriff des Anspruches 1.The invention relates to an adjustable bracket for posts according to the preamble of claim 1.

Durch die DE-A-34 36 091 ist eine Halterung für auf einem bodenfesten Träger lösbar zu befestigende Pfosten bekannt, die als zum Absperren dienende Poller verwendet werden. Die Halterung enthält einen den Pfosten aufnehmenden Haltering, der durch eine Bajonettverbindung mit dem Träger verbunden ist. Sofern es sich bei dem Träger um Baumroste handelt, ist diese Halterung nur dann uneingeschränkt verwendbar, wenn sich die Baumroste in einer im wesentlichen horizontalen Ebene befinden, weil nur in diesem Fall die stets senkrecht zur Ebene der Baumroste verlaufenden Pfosten vertikal ausgerichtet sind.From DE-A-34 36 091 a holder for posts to be releasably attached to a floor-mounted support is known, which are used as bollards serving to shut off. The bracket contains a retaining ring receiving the post, which is connected to the carrier by a bayonet connection. If the support is tree grids, this holder can only be used without restriction if the tree grids are in a substantially horizontal plane, because only in this case the posts, which are always perpendicular to the plane of the tree grates, are aligned vertically.

Die CH-A-643 904 offenbart eine Halterung für eine auf einem Träger lösbar zu befestigende Trägerstange eines Verkehrsleitelementes, wobei die Halterung ein Kugelgelenk aufweist, das aus einem zweiteiligen, durch Schraubmittel gegeneinander verspannbaren Gehäuse und einer in diesem angeordneten Kugel besteht. Zur Verbindung der Trägerstange mit der Kugel weist diese eine Bohrung auf und ist als ein Spannfutter ausgebildet, das beim gegenseitigen Verspannen der Gehäuseteile des Kugelgelenkes die Trägerstange mit festklemmt. Bei einer alternativen Ausführung trägt die Kugel eine Sockelhülse, in die die Trägerstange einsetzbar ist. Bei beiden Ausführungsformen liegt ein Teil der Gelenkflächen des Kugelgelenkes frei, so daß diese verschmutzen können, was zu einem ungewollten Verklemmen der Gelenkteile führen kann.CH-A-643 904 discloses a holder for a support rod of a traffic control element which can be detachably fastened to a carrier, the holder having a ball joint which consists of a two-part housing which can be clamped against one another by screwing means and a ball arranged therein. To connect the support rod to the ball, this has a bore and is designed as a chuck, which clamps the support rod when the housing parts of the ball joint are clamped together. In an alternative embodiment, the ball carries a base sleeve into which the support rod can be inserted. In both embodiments, a part of the joint surfaces of the ball joint is exposed, so that they can become dirty, which can lead to an undesired jamming of the joint parts.

Der Erfindung liegt die Aufgabe zugrunde, eine mit einem Kugelgelenk versehene einstellbare Halterung für Pfosten zu schaffen, bei der das Kugelgelenk gegen ein Verschmutzen geschützt ist. Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The invention has for its object to provide an adjustable bracket for posts provided with a ball joint, in which the ball joint is protected against contamination. The object is achieved by the characterizing features of claim 1.

Durch die Maßnahme, dem dem Pfosten zugewandten Gehäuseteil des Kugelgelenkes eine konzentrisch zum Gelenkmittelpunkt verlaufende halbkugelförmige Gestalt zu geben und am Pfosten einen entsprechend halbkugelförmig ausgebildeten Kragen vorzusehen, wird die Durchtrittsöffnung im Gehäuseteil bei jeder Schwenkstellung des Pfostens wirkungsvoll abgedeckt, wodurch die Gelenkflächen gegen Verschmutzen geschützt sind.By the measure, the housing part facing the post of the To give a spherical joint a hemispherical shape that runs concentrically to the center of the joint and to provide a correspondingly hemispherical collar on the post, the passage opening in the housing part is effectively covered with every pivoting position of the post, thereby protecting the articular surfaces against contamination.

Die US-A-3 676 965 offenbart eine Halterung für Pfosten auf einem Erdfundament, bei der die Halterung ein kugelgelenkähnliches Gelenk aufweist, das vom stirnseitigen Ende eines mit dem Fundament verbundenen zylindrischen Rohres und einer mit dem Pfosten verbundenen, auf dem Rohrende aufliegenden Halbkugel gebildet ist. Zum gegenseitigen Verspannen der Gelenkteile ist am Ende des Rohres ein erster Flansch und zwischen der Halbkugel und dem Ende des Pfostens ein an diesem befestigter zweiter Flansch vorgesehen, wobei die beiden Flansche durch mehrere Schrauben miteinander verbunden sind. Da der obere Flansch einen wesentlich größeren Durchmesser als die Halbkugel hat, deckt er zwar die Gelenkflächen ab, jedoch braucht er keine Schutzfunktion gegen ein Verschmutzen auszuüben, da sich die Gelenkteile nur linienförmig berühren und daher gar keine Gefahr eines durch Eindringen von Sand und Staub bedingten ungewollten Verklemmens des Gelenkes besteht. Wie Fig. 3 dieser Druckschrift zeigt, ist darüber hinaus eine solche Abdeck- bzw. Schutzfunktion auch gar nicht beabsichtigt, da dort der Zwischenraum zwischen den beiden Flanschen mit Mörtel ausgefüllt ist. Daher konnte die bekannte Halterung keine Anregung für die Entwicklung der erfindungsgemäßen Halterung gegeben haben.US-A-3 676 965 discloses a bracket for posts on an earth foundation, in which the bracket has a ball joint-like joint formed by the front end of a cylindrical tube connected to the foundation and a hemisphere connected to the post and resting on the tube end is. For mutual bracing of the joint parts, a first flange is provided at the end of the tube and a second flange fastened to it between the hemisphere and the end of the post, the two flanges being connected to one another by several screws. Since the upper flange has a much larger diameter than the hemisphere, it covers the articular surfaces, but it does not have to perform a protective function against contamination, since the articulated parts only touch in a linear manner and therefore do not pose a risk of sand and dust penetration there is unwanted jamming of the joint. As shown in FIG. 3 of this document, such a covering or protective function is also not intended, since the space between the two flanges is filled with mortar. Therefore, the known holder could not have given any suggestion for the development of the holder according to the invention.

Die Ausgestaltung der einstellbaren Halterung nach Anspruch 2 erleichtet die Anbringung der Halterung auf Baumrosten, indem die Halterung mitsamt dem Pfosten im vormontierten Zustand im Bereich der Baumrostschlitze an beliebigen Stellen aufgesetzt und festgeschraubt werden kann.The design of the adjustable bracket according to claim 2 facilitates the attachment of the bracket on tree grids by the bracket together with the post in the preassembled state in the area of the tree grate slots at any point and can be screwed.

Durch die weitergehende Ausgestaltung der einstellbaren Halterung bezüglich der Verbindung von Pfosten und Kugelkopf gemäß Anspruch 3 lassen sich auch solche Pfosten verwenden, die eine unter Umständen dünne und daher druckempfindliche Hülse aufweisen.Due to the further configuration of the adjustable holder with respect to the connection of the post and the ball head according to claim 3, it is also possible to use posts which may be one have a thin and therefore pressure-sensitive sleeve.

Bei der Ausbildung der einstellbaren Halterung gemäß Anspruch 4 dringen beim Anziehen der Schraubmittel die Ansätze zumindest teilweise in das Material des jeweils zugeordneten Bauelementes ein und bewirken dadurch, daß die reibschlüssige Haltewirkung der den Kugelkopf zwischen sich einklemmenden Gehäuseteile durch eine formschlüssige Haltewirkung unterstützt wird. Durch diese Maßnahme ist nunmehr die Haltewirkung der neuen Halterung so groß, daß die Pfosten auch für das Tragen von z. B. Sitzbänken oder Fahrradständern verwendet werden können.In the formation of the adjustable holder according to claim 4, the lugs penetrate at least partially into the material of the respectively assigned component when tightening the screw means and thereby cause the frictional holding action of the ball head which is clamped between them by a positive locking action. By this measure, the holding effect of the new bracket is now so great that the post for carrying z. B. benches or bike racks can be used.

Durch die Weiterbildung nach Anspruch 5 werden die Ansätze auf besonders einfache Weise hergestellt, wobei die beim Gießen entstehende harte Gußhaut für die notwendige Härte der Ansätze sorgt. Damit nun das Gegenstück von geringerer Härte ist, kann hierfür beispielsweise ein weicheres Material verwendet werden oder es wird, sofern das Gegenstück ebenfalls aus Gußeisen besteht und durch Gießen hergestellt wurde, die Gußhaut entfernt.Through the development according to claim 5, the approaches are produced in a particularly simple manner, the hard cast skin which is formed during casting ensuring the necessary hardness of the approaches. So that the counterpart is now of lower hardness, a softer material can be used for this purpose, for example, or if the counterpart also consists of cast iron and was produced by casting, the cast skin is removed.

Die Erfindung ist anhand eines in der Zeichnung dargestellten Ausführungsbeispieles erläutert. Es zeigen:

  • Fig. 2 eine Draufsicht auf die auf einem Träger angeordnete Halterung mit Angabe des Schnittverlaufes von Fig. 1;
  • Fig. 3 eine vergrößerte Schnittdarstellung eines der in Fig. 1 dargestellten vorspringenden Ansätze;
  • Fig. 4 eine Schnittdarstellung eines Ansatzes nach Linie IV-IV der Fig. 3.
The invention is explained with reference to an embodiment shown in the drawing. Show it:
  • Figure 1 is a sectional view of the bracket with a post partially shown.
  • FIG. 2 shows a plan view of the holder arranged on a carrier, with an indication of the sectional profile of FIG. 1;
  • Fig. 3 is an enlarged sectional view of one of the protruding approaches shown in Fig. 1;
  • 4 is a sectional view of an approach according to line IV-IV of FIG. 3rd

Der in Fig. 1 teilweise dargestellte Pfosten (1) weist eine Hülse (2) mit einem am unteren Ende vorgesehenen Kragen (2a) und einen Kugelzapfen (3) auf, der aus einem Kugelkopf (4) und einem in die Hülse (2) hineinragenden zylindrischen Zapfenteil (5) besteht. Die Hülse (2) läßt sich mit Hilfe eines Distanzringes (6) und mehrerer Gewindestifte (7) in der Weise mit dem Kugelzapfen (3) verbinden, daß die durch Durchgangsbohrungen (8) in der Hülse (2) hineinragenden, im Distanzring (6) eingeschraubten Gewindestifte (7) gegen den Zapfenteil (5) angezogen werden, wodurch der Distanzring (6) auf dem Zapfenteil (5) festgeklemmt ist. Nach dem Anziehen der Gewindestifte (7) wird auf die über die Außenseite der Hülse (2) überstehenden Enden der Gewindestifte (7) je eine Hutmutter (9) aufgeschraubt und festgezogen, wodurch die Hülse (2) gegen die Außenseite des Distanzringes (6) festgeklemmt ist.The post (1) partially shown in FIG. 1 has a sleeve (2) with a collar (2a) provided at the lower end and one Ball pin (3), which consists of a ball head (4) and a cylindrical pin part (5) protruding into the sleeve (2). The sleeve (2) can be connected to the ball stud (3) with the aid of a spacer ring (6) and several setscrews (7) in such a way that the through holes (8) in the sleeve (2) project into the spacer ring (6 ) screwed set screws (7) against the pin part (5), whereby the spacer ring (6) is clamped on the pin part (5). After tightening the grub screws (7), a cap nut (9) is screwed and tightened onto the ends of the grub screws (7) protruding from the outside of the sleeve (2), whereby the sleeve (2) against the outside of the spacer ring (6) is clamped.

Die Halterung (10) für den Pfosten (1) ist als ein den Kugelkopf (4) umschließendes zweiteiliges Gehäuse (11) ausgebildet, das aus einer flachen Trägerplatte (12) und einer hutförmigen Klemmplatte (13) besteht. Die Klemmplatte (13) setzt sich aus einem ebenflächigen Flanschteil (13a) und einem halbkugelförmigen Formteil (13b) zusammen und weist eine Durchgangsbohrung (14) für den Zapfenteil (5) auf, die wesentlich größer als der Durchmesser des Zapfenteiles (5) ist, so daß der Kugelzapfen (3) mitsamt der Hülse (2) relativ zur Halterung (10) verschwenkt und dadurch ausgerichtet werden kann.The bracket (10) for the post (1) is designed as a two-part housing (11) enclosing the ball head (4), which consists of a flat carrier plate (12) and a hat-shaped clamping plate (13). The clamping plate (13) is composed of a flat flange part (13a) and a hemispherical shaped part (13b) and has a through hole (14) for the pin part (5) which is significantly larger than the diameter of the pin part (5), so that the ball pin (3) together with the sleeve (2) can be pivoted relative to the holder (10) and thereby aligned.

Die Außenseite des Formteiles (13b) weist eine konzentrisch zum Mittelpunkt des Kugelkopfes (4) verlaufende halbkugelförmige Fläche (13c) auf. Wie der Zeichnung zu entnehmen ist, ist die Innenseite des Kragens (2a) entsprechend der Fläche (13c) konkav kugelförmig ausgebildet, wobei zwischen der Innenfläche des Kragens (2a) und der Fläche (13c) ein schmaler äquidistanter Spalt besteht. Der Durchmesser des Kragens (2a) ist hierbei so groß gewählt, daß der Kragen (2a) bei jeder Schwenkstellung des Pfosten (1) die Durchgangsbohrung (14) abdeckt und sie damit gegen ein Verschmutzen schützt.The outside of the molded part (13b) has a hemispherical surface (13c) which runs concentrically to the center of the spherical head (4). As can be seen in the drawing, the inside of the collar (2a) has a concave spherical shape corresponding to the surface (13c), with a narrow, equidistant gap between the inside surface of the collar (2a) and the surface (13c). The diameter of the collar (2a) is chosen so large that the collar (2a) covers the through hole (14) in each pivoting position of the post (1) and thus protects it against contamination.

Die Trägerplatte (12) und Klemmplatte (13) bestehen aus Grauguß und sind durch Gießen hergestellt. Sie enthalten an den dem Kugelkopf (4) zugekehrten Flächen je drei von Angüssen gebildete keilförmige Ansätze (15), die durch die beim Gießen entstehende Gußhaut eine große Härte aufweisen. Im Gegensatz dazu weist der Kugelkopf (4) eine vergleichsweise geringere Härte auf, die dadurch erreicht wird, daß entweder für den Kugelzapfen (3) ein weicherer Werkstoff gewählt, oder - sofern der Kugelzapfen (3) auch aus Grauguß besteht und durch Gießen hergestellt wurde - die Gußhaut am Kugelkopf (4) entfernt wird.The carrier plate (12) and clamping plate (13) consist of gray cast iron and are produced by casting. On the surfaces facing the spherical head (4), they each contain three wedge-shaped projections (15) formed by castings, which are extremely hard due to the casting skin which is produced during casting exhibit. In contrast, the ball head (4) has a comparatively lower hardness, which is achieved by either choosing a softer material for the ball pin (3) or - if the ball pin (3) also consists of gray cast iron and was produced by casting - The cast skin on the ball head (4) is removed.

Zur Befestigung der Halterung (10) auf einem in Fig. 2 strichpunktiert dargestellten Baumrost (16) sind durch mehrere miteinander fluchtende Durchgangsbohrungen (17) der Träger- und der Klemmplatte (12, 13) entsprechend viele Schrauben (18) hindurchgesteckt, die an ihrem unteren Ende je einen länglichen Kopf (19) aufweisen. Die Schraubenköpfe (19) können bei entsprechender Ausrichtung durch die Schlitze (20) des Baumrostes (16) hindurchgesteckt werden, worauf die Kopfenden durch Verdrehen der Schrauben (18) um 90° unter je zwei benachbarten Rippen (21) des Baumrostes (16) plaziert werden. Jede Schraube (18) trägt eine Unterlagscheibe (22) und eine Hutmutter (23).To fasten the bracket (10) to a tree grate (16) shown in dash-dotted lines in FIG. 2, a plurality of screws (18) are inserted through a plurality of mutually aligned through bores (17) in the support plate and the clamping plate (12, 13) each have an elongated head (19). The screw heads (19) can be inserted through the slots (20) of the tree grate (16) with appropriate alignment, whereupon the head ends are placed under two adjacent ribs (21) of the tree grate (16) by turning the screws (18) by 90 ° will. Each screw (18) carries a washer (22) and a cap nut (23).

Zum leichteren Anbringen der Pfosten (1) auf einem Baumrost (16) werden die Pfosten (1) und die zugeordneten Halterungen (10) im vormontierten Zustand verwendet. Dadurch bedingt, brauchen dann nach dem Aufsetzen einer mit einem Pfosten (1) versehenen Halterung (10) auf der vorgesehenen Stelle des Baumrostes (16) und dem Durchstrecken der Schraubenköpfe (19) durch die Schlitze (20) die Schrauben (18) nur noch um jeweils 90° gedreht und nach dem vertikalen Ausrichten des Pfostens (1) die Hutmuttern (23) angezogen zu werden. Beim Anziehen der Hutmuttern (23) wird einerseits die Halterung (10) auf dem Baumrost (16) festgeklemmt und andererseits die Klemmplatte (13) gegen den Kugelkopf (4) angepreßt. Hierbei dringen die Ansätze (15) teilweise in den Kugelkopf (4) ein und bewirken dadurch, daß die reibschlüssige Haltewirkung der den Kugelkopf (4) zwischen sich einklemmenden Platten (12, 13) durch eine formschlüssige Haltewirkung unterstützt wird.To make it easier to attach the posts (1) to a tree grate (16), the posts (1) and the associated brackets (10) are used in the preassembled state. As a result, after the attachment of a bracket (10) provided with a post (1) to the intended location of the tree grate (16) and the screw heads (19) extending through the slots (20), the screws (18) only need rotated by 90 ° and after the vertical alignment of the post (1) the cap nuts (23) have to be tightened. When tightening the cap nuts (23), the holder (10) is clamped on the tree grate (16) and the clamping plate (13) is pressed against the ball head (4). The lugs (15) penetrate partially into the ball head (4) and thereby cause the frictional holding action of the plates (12, 13) which clamp the ball head (4) between them to be supported by a positive locking action.
