Description

Die Erfindung betrifft eine Vorrichtung zur Befestigung einer Bake an einer Fußplatte, mit einem am unteren Ende der Bake angeordneten Fußstück, das in eine Steckaufnahme der Fußplatte einsteckbar ist und an seinem Umfang Bajonettvorsprünge für die Verriegelung an Bajonettkonturen, die durch L-förmige Nuten in der Innenwand der Steckaufnahme gebildet werden, aufweist.The invention relates to a device for fastening a beacon to a footplate, with a foot piece arranged at the lower end of the beacon, which in a plug-in receptacle of the footplate can be inserted and bayonet projections on its circumference for locking on bayonet contours through L-shaped Grooves are formed in the inner wall of the receptacle.

Baken, die aufrecht stehend auf Fußplatten befestigt sind, werden insbesondere für Straßenabsperrungen an Baustellen eingesetzt.Beacons that are mounted upright on footplates are particularly popular used for road closures on construction sites.

Bei einer aus EP 0 355 440 B1 bekannten Befestigungsvorrichtung hat das Fußstück der Bake einen kreisförmigen Außenquerschnitt, und die Bajonettvorsprünge werden durch einen durch das Fußstück gesteckten Querstift aus Metall gebildet, der mit beiden Enden über die Umfangsfläche vorsteht. In Abstand oberhalb des Querstiftes bildet das Fußstück einen Anschlag in der Form eines Kragens, der sich an einer Gegenfläche der Fußplatte abstützt und so die Einstecktiefe des Fußstückes in die Fußplatte begrenzt. Die Bajonettkonturen der Steckaufnahme, die in der Verriegelungsstellung ein Zurückziehen des Querstiftes nach oben verhindern, weisen ein Rastgebirge auf, auf das der Querstift aufläuft, wenn das Fußstück in der Steckaufnahme gedreht wird. Dabei wird der Kragen des Fußstückes fest gegen die Gegenfläche der Fußplatte gespannt, bis der Querstift einen Totpunkt des Rastgebirges überwindet und in der endgültigen Verriegelungsstellung einrastet. Damit die Bake starr und ohne zu kippeln in der Fußplatte fixiert wird, sind der Anschlag am Fußstück und die Gegenfläche an der Fußplatte zumeist konisch ausgebildet.In a fastening device known from EP 0 355 440 B1, the foot piece has the beacon has a circular outer cross section, and the bayonet projections are made by a metal cross pin inserted through the foot piece formed, which protrudes with both ends over the peripheral surface. At a distance Above the cross pin, the foot piece forms a stop in the shape of a Collar, which is supported on a counter surface of the footplate and thus the insertion depth of the foot piece limited in the foot plate. The bayonet contours of the Plug-in receptacle which in the locking position pulls back the cross pin prevent upwards, have a ridge on which the cross pin runs, when the foot piece is turned in the socket. The Collar of the foot piece firmly clamped against the counter surface of the foot plate until the cross pin overcomes a dead center of the rest area and in the final Locking position engages. So that the beacon rigid and without tipping is fixed in the footplate, the stop on the footpiece and the counter surface mostly conical on the footplate.

Ein Nachteil dieser bekannten Konstruktion besteht darin, daß sich die miteinander in Eingriff stehenden Konusflächen oft nur schwer wieder voneinander lösen lassen. Dies gilt besonders dann, wenn die Fußplatte regennaß oder mit Schlamm verkrustet ist. Bei den Versuchen, die Bake gewaltsam aus der Steckaufnahme zu lösen, wird häufig das Bakenblatt verbogen.A disadvantage of this known construction is that the one another it is often difficult to separate the conical surfaces from each other again to let. This is especially true when the footplate is wet with rain or with Mud is encrusted. When trying to force the beacon out of the receptacle to solve, the beacon sheet is often bent.

Ein weiterer Nachteil besteht darin, daß das Rastgebirge an den Bajonettkonturen der aus Kunststoff bestehenden Steckaufnahme durch die Reibungswirkung des Querstiftes aus Metall einem starken Verschleiß unterliegt, der durch Sand und Schmutzpartikel noch verstärkt wird. Wenn der Kragen am Fußstück und/ oder die zugehörige Gegenfläche an der Fußplatte verschmutzt ist, kann der Bajonettverschluß so schwergängig sein, daß die Bajonettkonturen regelrecht abgeschält werden. Dies kann insbesondere nach längerem Gebrauch dazu führen, daß sich die Steckverbindung zwischen dem Fußstück und der Fußplatte lokkert. Andererseits kann sich jedoch das abgeschälte Material auch so in der Steckaufnahme verklemmen, daß sich die Bake nicht mehr lösen läßt.Another disadvantage is that the locking mountains on the bayonet contours the plug socket made of plastic due to the friction effect the metal cross pin is subject to heavy wear caused by sand and dirt particles is reinforced. If the collar on the foot piece and / or the associated counter surface on the footplate is dirty, the bayonet lock can be so stiff that the bayonet contours literally peeled off become. Especially after prolonged use, this can lead to that the plug connection between the foot piece and the foot plate is loosened. On the other hand, the peeled material can also be found in the Clamp the plug receptacle so that the beacon can no longer be detached.

Bei einer aus GB 2 172 920 A bekannten Bake ist ein Bajonettverschluß vorgesehen, mit dem die in ein Fußteil eingesteckte, flache Bake verriegelt wird. Die Bake weist zwei Bajonettvorsprünge auf, die in entsprechend geformte Schlitzfortsätze der Einstecköffnung des Fußteils passen. Auf der Unterseite des Fußteils sind die Schlitze über etwa 90° in Umfangsrichtung zu Ästen verbreitert, so daß L-förmige Aufnahmen für die Bajonettvorsprünge gebildet werden. Die Äste haben auf der Unterseite keine Begrenzung, sondern erstrecken sich bis zum Boden des Fußteils. Die Bake stützt sich im verriegelten Zustand mit der Unterkante des Bakenblattes auf die Oberseite des Fußteils auf.In the case of a beacon known from GB 2 172 920 A, a bayonet lock is provided, with which the flat beacon inserted into a foot part is locked. The Beacon has two bayonet projections, which are formed in appropriately shaped slot processes the insertion opening of the foot section. On the bottom of the foot section the slots are widened to branches in the circumferential direction over approximately 90 °, so that L-shaped receptacles for the bayonet projections are formed. The branches have no limit on the bottom, but extend to Bottom of the foot section. The beacon is supported with the lower edge in the locked state of the beacon blade on the top of the foot section.

Nachteilig ist bei dieser Konstruktion insbesondere der unsichere Halt der Bake, da zum einen keine Abstützung der Bake in Richtung quer zum Bakenblatt gegeben ist. Zum anderen können die Bajonettvorsprünge durch Gebrauch abnutzen, so daß keine feste Verriegelung mehr möglich ist. Die Bake kann daher lediglich kleine Ausmaße haben und beispielsweise als spitzes Dreieck zum Markieren von Fahrspuren dienen.A disadvantage of this construction is the unsafe hold of the beacon, because on the one hand there is no support for the beacon in the direction transverse to the beacon sheet is. Secondly, the bayonet protrusions can wear through use, so that a fixed lock is no longer possible. The beacon can only have small dimensions and, for example, as a pointed triangle for marking serve from lanes.

Aus dem deutschen Gebrauchsmuster DE 201 16 571.6 ist eine Vorrichtung zur Befestigung einer Bake an einer Fußplatte bekannt, die sich gegenüber den oben genannten Vorrichtungen durch eine erhöhte Haltbarkeit und Funktionssicherheit auszeichnet und unempfindlich gegenüber Verschmutzung ist. Die Bake weist ein an ihrem unteren Ende angeordnetes Fußstück auf, das in eine Steckaufnahme der Fußplatte einsteckbar ist und an seinem Umfang vier Bajonettvorsprünge für die Verriegelung an Bajonettkonturen der Steckaufnahme aufweist. Die Bajonettkonturen werden durch L-förmige Nuten in der Innenwand der Steckaufnahme gebildet, und die in Umfangsrichtung verlaufenden Äste dieser Nuten haben eine lichte Höhe, die gleich der Höhe der Bajonettvorsprünge ist.From the German utility model DE 201 16 571.6 a device for Attaching a beacon to a footplate known to be opposite the above mentioned devices through increased durability and functional reliability distinguished and insensitive to pollution. The beacon has a foot piece arranged at its lower end, which in a plug receptacle the footplate is insertable and four bayonet projections on its circumference for locking to bayonet contours of the plug receptacle. The bayonet contours are formed by L-shaped grooves in the inner wall formed of the plug-in receptacle, and the branches running in the circumferential direction Grooves have a clear height that is equal to the height of the bayonet projections is.

Da die in Umfangsrichtung verlaufenden Äste der Nuten in der Höhe an die Bajonettvorsprünge angepaßt sind, ergibt sich in der Verriegelungsstellung ein formschlüssiger Eingriff, durch den das Fußstück axialfest in der Steckaufnahme gehalten wird. Die Bajonettvorsprünge und die damit zusammenwirkenden Nuten verhindern somit nicht nur ein Zurückziehen des Fußstückes nach oben, sondern begrenzen zugleich auch die Einstecktiefe des Fußstückes nach unten, so daß am Fußstück kein zusätzlicher Anschlag vorgesehen zu sein braucht. Zugleich wird durch den formschlüssigen Eingriff der Bajonettvorsprünge in die Nuten eine kippstabile Befestigung des Fußstückes in der Steckaufnahme gewährleistet, so daß insbesondere auch keine ineinandergreifenden Konusflächen erforderlich sind, die sich nur schwer wieder voneinander lösen ließen. Da die in Umfangsrichtung verlaufenden Äste der Nuten im Inneren der Steckaufnahme liegen, sind sie gut gegen Verschmutzung geschützt. Da außerdem das Fußstück und die Fußplatte nicht axial gegeneinander verspannt werden, wenn der Bajonettverschluß in die Verriegelungsstellung gedreht wird, sind die Bajonettkonturen weniger verschleißgefährdet.Since the branches of the grooves running in the circumferential direction are at the height of the bayonet projections are adjusted, results in the locking position positive engagement, through which the foot piece is axially fixed in the socket is held. The bayonet projections and the interacting ones Grooves not only prevent the foot piece from being pulled back upwards, but at the same time limit the insertion depth of the foot piece downwards, so that no additional stop needs to be provided on the foot piece. At the same time, the form-fitting engagement of the bayonet projections in the Grooves ensure a tilt-stable attachment of the foot piece in the plug receptacle, so that in particular no interlocking conical surfaces are required that are difficult to separate from each other. Since the in Circumferential branches of the grooves inside the plug receptacle are well protected against pollution. Since also the foot piece and the base plate can not be clamped axially against each other when the Bayonet lock is turned into the locking position, the bayonet contours less risk of wear.

Eine Verrastung des Fußstückes in der Verriegelungsstellung kann durch Rasteinrichtungen erreicht werden, die getrennt von den Bajonettvorsprüngen und den Bajonettkonturen ausgebildet sind. Beispielsweise können diese Rasteinrichtungen durch axial in der Umfangswand des Fußstückes angeordnete federnde Zungen im Bereich des unteren Endes dieses Fußstücks gebildet werden, die in der Höhe versetzt zu den Rastvorsprüngen und den Rastkonturen angeordnet sind und die in zugehörige Rasten einfallen, wenn das Fußstück in die Verriegelungsstellung gedreht wird.A locking of the foot piece in the locking position can be done by locking devices can be achieved, which are separate from the bayonet projections and the bayonet contours are formed. For example, these locking devices by resilient axially arranged in the peripheral wall of the foot piece Tongues are formed in the area of the lower end of this foot piece, which are offset in height from the locking projections and the locking contours are arranged and fall into associated pegs when the foot piece in the locking position is turned.

Aufgabe der Erfindung ist es, eine Vorrichtung zur Befestigung einer Bake an einer Fußplatte zu schaffen, die eine Arretierung der Bake im verriegelten Zustand ermöglicht und zugleich bei hoher Haltbarkeit und Funktionssicherheit einen einfacheren und robusteren Aufbau des Fußstückes der Bake erlaubt.The object of the invention is to provide a device for attaching a beacon to a To create a footplate that locks the beacon in the locked state enables and at the same time with high durability and functional reliability simpler and more robust construction of the foot piece of the beacon allowed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei einer Vorrichtung der eingangs genannten Art mindestens einer der in Umfangsrichtung verlaufenden Äste der Nuten mindestens eine Rastfeder zur Verrastung eines Bajonettvorsprungs aufweist, die im entspannten Zustand die lichte Höhe des Astes auf ein Maß einschränkt, das kleiner als die Höhe der Bajonettvorsprünge ist.This object is achieved in that in a device of the type mentioned at least one of those extending in the circumferential direction Branches of the grooves at least one detent spring for locking a bayonet projection has the clear height of the branch on in a relaxed state Restricted dimension that is smaller than the height of the bayonet projections.

Da auf diese Weise eine Verrastung der Bajonettvorsprünge durch die im Inneren der Fußplatte geschützte Rastfeder ermöglicht wird, sind an dem Fußstück der Bake außer den Bajonettvorsprüngen, die sehr einfach gestaltet sein können, keine weiteren Elemente nötig. Das Fußstück der Bake ist daher entsprechend robust. Dennoch ist ein sicherer Halt der Bake gegeben, da aufgrund der Verrastung lediglich kurze waagerechte Äste der Nuten zur Verriegelung des Bajonettverschlusses nötig sind, so daß beispielsweise vier solche Äste in Umfangsrichtung des Fußstückes verteilt angeordnet sein können. Das Fußstück der Bake kann sich dann auf vier Seiten mit den Bajonettvorsprüngen in den Ästen der Nuten abstützen und kann außerdem durch im wesentlichen zylindrisch formschlüssige Konturflächen des Fußstücks und der Steckaufnahme gegen Verkippen gesichert sein.In this way, the bayonet projections snap into place thanks to the inside Protected locking spring of the footplate is possible on the footpiece the beacon except the bayonet protrusions, which can be very simple, no further elements necessary. The base of the beacon is therefore appropriate robust. Nevertheless, the beacon is held securely because of the Locking only short horizontal branches of the grooves to lock the bayonet lock are necessary so that, for example, four such branches in the circumferential direction of the foot piece can be arranged distributed. The footpiece of the The beacon can then be on four sides with the bayonet projections in the branches of the grooves and can also be essentially cylindrical form-fitting contour surfaces of the foot piece and the plug receptacle against Tilt be secured.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous embodiments of the invention result from the subclaims.

Bevorzugt ist mindestens eine der Rastfedern in der Verriegelungsstellung der Bajonettvorsprünge im wesentlichen entspannt. Ein solcher Aufbau beugt Materialermüdung derjenigen Rastfedern vor, die lediglich zum Verriegeln oder Entriegeln der Bake beansprucht werden müssen.At least one of the detent springs is preferred in the locked position Bayonet projections essentially relaxed. Such a structure prevents material fatigue of those detent springs that only for locking or unlocking the beacon needs to be claimed.

Bevorzugt sind die Rastfedem jeweils an der Unterseite der in Umfangsrichtung verlaufenden Äste der Nuten in Form von zwei in Umfangsrichtung des Fußstückes aufeinander zu gerichteten Rastzungen angeordnet, die durch einen umgekehrt T-förmigen Ausschnitt in der Wand der Steckaufnahme voneinander getrennt sind und jeweils einen nach oben in die Nut hineinragenden, angeschrägten Rastvorsprung aufweisen. Je nach Formgebung der Bajonettvorsprünge und Nuten können die Rastvorsprünge in der Verriegelungsstellung zwischen einer der zwei Rastzungen und der Oberseite der Nut eingeklemmt sein, oder es können beide Rastzungen entspannt sein.The detent springs are preferably on the underside of the circumferential direction extending branches of the grooves in the form of two in the circumferential direction of the foot piece Arranged towards each other latching tongues, which by a reversed T-shaped cutout in the wall of the plug receptacle from each other are separated and each have a beveled protruding upwards into the groove Have locking projection. Depending on the shape of the bayonet projections and grooves can the locking projections in the locking position clamped between one of the two locking tongues and the top of the groove or both latching tongues can be relaxed.

Bevorzugt weist das Fußstück auf seiner äußeren Umfangsfläche vier in Winkelabständen von 90° angeordnete Bajonettvorsprünge auf und wird durch ein rohrförmiges Formteil aus Kunststoff gebildet. Die Bajonettkonturen der Steckaufnahme werden dementsprechend durch vier L-förmige Nuten gebildet.The foot piece preferably has four on its outer peripheral surface at angular intervals of 90 ° arranged bayonet projections and is replaced by a tubular molded part made of plastic. The bayonet contours of the socket are accordingly formed by four L-shaped grooves.

In einer besonders bevorzugten Ausführungsform ist die Steckaufnahme als ein Adapter aus Kunststoff ausgebildet, der insgesamt einen quadratischen Außenquerschnitt hat. Fußplatten für Baken und andere Absperrgeräte weisen standardmäßig ein quadratisches Einsteckloch mit einer Kantenlänge von 60 mm auf. Der die Steckaufnahme bildende Adapter ist so ausgebildet, daß er in dieses quadratische Loch eingesteckt und mit in seiner Außenwand ausgebildeten federnden Rastklinken in dem Loch der Fußplatte verrastet werden kann. Wenn dann das Fußstück der Bake eingeführt und verriegelt wird, werden die Rastklinken durch das Fußstück von innen abgestützt, so daß der Adapter zuverlässig gegen ein Herausreißen aus dem Loch der Fußplatte gesichert ist. Auf diese Weise ermöglicht die erfindungsgemäße Vorrichtung eine sichere und stabile Befestigung der Bake an Fußplatten aller gängigen Typen.In a particularly preferred embodiment, the plug receptacle is as one Adapter made of plastic, the total of a square outer cross section Has. Base plates for beacons and other shut-off devices have standard a square insertion hole with an edge length of 60 mm on. The adapter forming the plug-in adapter is designed so that it fits into this square hole inserted and with resilient formed in its outer wall Latches can be locked in the hole in the footplate. If then the foot piece of the beacon is inserted and locked, the Latches supported by the foot piece from the inside, so that the adapter is reliable is secured against tearing out of the hole in the footplate. On in this way, the device according to the invention enables a safe and stable Attachment of the beacon to base plates of all common types.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert.The following is an embodiment of the invention with reference to the drawing explained in more detail.

In Figur 1 ist der untere Teil einer Bake 10 zu erkennen, die am unteren Ende ein Fußstück 12 aufweist, mit dem sie lösbar in einer Fußplatte 14 verriegelt ist. Die Fußplatte 14 weist in der Mitte ein quadratisches Einsteckloch 16 mit einer Kantenlänge von 60 mm auf. Ein Adapter 18 aus Kunststoff weist einen an den Innenquerschnitt des Einsteckloches 16 angepaßten quadratischen Außenquerschnitt auf und ist von oben in das Einsteckloch 16 eingesteckt. Ein am oberen Ende des Adapters 18 angeformter kreisförmiger Bund 20 liegt auf der Oberseite der Fußplatte 14 auf. Am unteren Ende weist der Adapter 18 mehrere Rastklinken 22 auf, die unter die Unterseite der Fußplatte 14 greifen und in einem durch Fußhöcker 24 der Fußplatte geschaffenen Bodenfreiraum liegen. Das Fußstück 12 ist in den Adapter 18 eingesteckt und stützt dic Rastklinken 22 von innen ab, so daß diese Rastklinken nicht mehr nachgeben können, nachdem die Bake in den Adapter eingesteckt worden ist. Auf diese Weise wird durch die Rastklinken 22 zuverlässig verhindert, daß die Bake 10 zusammen mit dem Adapter 18 nach oben aus der Fußplatte 14 herausgerissen wird.In Figure 1, the lower part of a beacon 10 can be seen, which is at the lower end has a foot piece 12 with which it is releasably locked in a foot plate 14. The base plate 14 has a square insertion hole 16 with a center Edge length of 60 mm. An adapter 18 made of plastic has one on the Inner cross section of the insertion hole 16 adapted square outer cross section and is inserted from above into the insertion hole 16. One at the top The circular collar 20 formed on the end of the adapter 18 lies on the top the base plate 14. At the lower end, the adapter 18 has several latches 22, which engage under the underside of the base plate 14 and in one ground clearance created by bumps 24 of the footplate. The Foot piece 12 is inserted into adapter 18 and supports latches 22 from the inside, so that these pawls can no longer give in after the beacon has been inserted into the adapter. This way, through the latches 22 reliably prevents the beacon 10 together with the Adapter 18 is torn up out of the base plate 14.

Der Adapter 18 wird nun mit Bezug auf Figuren 2 bis 4 näher beschrieben. Bei diesem Adapter handelt es sich um einen Hohlkörper aus Kunststoff. Die Rastklinken 22 werden durch Teile der Wand dieses Hohlkörpers gebildet, die durch Schlitze voneinander getrennt sind. Vertikale Kufen 26 an den Außenflächen der Wände des Adapters 18 erleichtern das paßgenaue Einführen des Adapters in das Einsteckloch 16 der Fußplatte.The adapter 18 will now be described in more detail with reference to FIGS. 2 to 4. at this adapter is a hollow body made of plastic. The Latches 22 are formed by parts of the wall of this hollow body, the are separated from each other by slots. Vertical runners 26 on the outer surfaces the walls of the adapter 18 facilitate the precise insertion of the adapter in the insertion hole 16 of the footplate.

Wie in Figur 3 zu erkennen ist, weisen der kreisförmige Flansch 20 und der obere Teil des Adapters 18 eine kreisförmige Steckaufnahme 28 auf, in deren Innenwand vier in Winkelabständen von 90° angeordnete Bajonettkonturen 30 ausgebildet sind. Bei diesen Bajonettkonturen handelt es sich um L-förmige Nuten, von denen in Figur 3 nur die vertikalen Äste 32 zu erkennen sind. Waagerechte Äste 34, die sich L-förmig an die unteren Enden der Äste 32 anschließen, sind in Figuren 2 und 4 als im wesentlichen rechteckige, fensterartige Durchbrüche in der Wand des Adapters zu erkennen.As can be seen in Figure 3, the circular flange 20 and the top Part of the adapter 18 has a circular plug receptacle 28 in the inner wall four bayonet contours 30 arranged at angular intervals of 90 ° are. These bayonet contours are L-shaped grooves, of which only the vertical branches 32 can be seen in FIG. 3. horizontal Branches 34 which are L-shaped at the lower ends of the branches 32 are in Figures 2 and 4 as a substantially rectangular, window-like openings recognizable in the wall of the adapter.

An ihrer Unterseite weisen die waagerechten Äste 34 jeweils mittig zwei Rastfedem 35 in Form von Rastzungen auf, die in Umfangsrichtung des Fußstückes aufeinander zu gerichtet sind. Sie sind durch einen umgekehrt T-förmigen Ausschnitt 36 in der Wand des Adapters 18 voneinander getrennt und weisen jeweils einen nach oben in den Ast 34 hineinragenden, angeschrägten Rastvorsprung 37 auf. Am rechten Ende des Ausschnittes 36 ist ist dieser lediglich im äußeren Teil der Wand des Adapters 18 fortgesetzt, nicht jedoch auf der Innenseite der Wand des Adapters 18, die die kreisförmige Steckaufnahme 28 bildet. Daher ist in Figur 2 eine Kante 38 der Innenseite der Wand des Adapters 18 sichtbar.On their underside, the horizontal branches 34 each have two detent springs in the center 35 in the form of locking tongues in the circumferential direction of the foot piece are directed towards each other. They are reversed in a T-shaped cutout 36 in the wall of the adapter 18 separated from each other and each have an inclined locking projection projecting upward into branch 34 37 on. At the right end of the cutout 36, this is only in outer part of the wall of the adapter 18 continued, but not on the inside the wall of the adapter 18, which forms the circular plug receptacle 28. Therefore, in FIG. 2 there is an edge 38 on the inside of the wall of the adapter 18 visible.

Wie weiterhin aus Figuren 3 und 4 hervorgeht, sind die vertikalen Äste 32 der L-förmigen Nuten nach unten durch schmalere vertikale Nuten 40 verlängert, die einen halbrunden Querschnitt haben und bis zu einem Absatz 41 (Figur 4) durchgehen, an dem sich der kreisförmige Innenquerschnitt der Mittelöffnung 28 zu einem rechteckigen Innenquerschnitt erweitert, der durch die Rastklinken 22 begrenzt wird. Die Nuten 40 ermöglichen die Kombination des Fußstückes der Erfindung mit einer aus dem oben genannten Gebrauchsmuster DE 201 16 571.6 bekannten Bake, und ihre Funktion ist dort näher erläutert.3 and 4, the vertical branches 32 are L-shaped Grooves extended downward by narrower vertical grooves 40 which have a semicircular cross-section and up to a shoulder 41 (FIG. 4) go through, on which the circular inner cross section of the central opening 28 expanded to a rectangular inner cross-section, which by the latches 22 is limited. The grooves 40 allow the combination of the foot piece of the invention with one of the above-mentioned utility model DE 201 16 571.6 known beacon, and its function is explained in more detail there.

In der Mitte jeder Seitenwand des Adapters 18 sind die Rastklinken 22 durch einen U-förmigen Ausschnitt voneinander getrennt.In the middle of each side wall of the adapter 18, the latches 22 are through one U-shaped neckline separated.

Wie weiterhin in Figur 3 zu erkennen ist, weist der Bund 20 zwei Schraubenlöcher 42 auf, die es gestatten, den Adapter 18 zusätzlich mit der Fußplatte 14 zu verschrauben. Diese Schraubbefestigung dient jedoch lediglich als Ergänzung zu der durch die Rastklinken 22 gebildeten Rastbefestigung. Da die Fußplatte 14 in der Regel aus einem verhältnismäßig inhomogenen Recyclingmaterial besteht, in dem Schrauben nur schlecht halten, bietet die Rastbefestigung mit Hilfe der Rastklinken 22 eine höhere Sicherheit.As can also be seen in FIG. 3, the collar 20 has two screw holes 42 on, which allow the adapter 18 additionally with the foot plate 14 screw. However, this screw fastening only serves as a supplement to the locking attachment formed by the latches 22. Since the base plate 14 in generally consists of a relatively inhomogeneous recycling material, in hold the screwing badly, the snap fastening with the help of Latches 22 provide greater security.

In Figur 5 ist der untere Teil der Bake 10 mit dem Fußstück 12 noch einmal gesondert dargestellt. Das Fußstück 12 ist als eine zylindrische Hülse aus Kunststoff ausgebildet, die am oberen Ende einen Flansch 44 und am unteren Ende eine Einführschräge 48 zum leichteren Einführen in die Steckaufnahme 28 des Adapters 18 aufweist. Auf der Umfangsfläche des Fußstückes 12 sind ungefähr in halber Höhe vier in Winkelabständen von 90° angeordnete Bajonettvorsprünge 50 angeformt, die die Umrißform eines Kreises haben.In Figure 5, the lower part of the beacon 10 with the foot piece 12 is again separate shown. The foot piece 12 is a cylindrical sleeve made of plastic formed a flange 44 at the upper end and at the lower end an insertion bevel 48 for easier insertion into the receptacle 28 of the Adapters 18 has. On the peripheral surface of the foot piece 12 are approximately at half height four bayonet projections arranged at angular intervals of 90 ° 50 molded, which have the outline shape of a circle.

Der Durchmesser dieses Kreises ist größer als die lichte Höhe zwischen der Oberseite der waagerechten Äste 34 der Bajonettkonturen 30 und den Rastvorsprüngen 37 im entspannten Zustand der Rastfedem 35. Der Durchmesser kann insbesondere auch mit der lichten Höhe der waagerechten Äste 34 der Bajonettkonturen übereinstimmen (Figur 6).The diameter of this circle is larger than the clear height between the Top of the horizontal branches 34 of the bayonet contours 30 and the locking projections 37 in the relaxed state of the detent springs 35. The diameter can in particular also with the clear height of the horizontal branches 34 of the bayonet contours agree (Figure 6).

Wenn das Fußstück 12 in den Adapter 18 eingesteckt und in der in Figur 1 gezeigten Weise verriegelt werden soll, so wird das Fußstück 12 zunächst in einer solchen Winkelposition von oben an den Adapter 18 angesetzt, daß die die Bajonettvorsprünge 50 mit den vertikalen Ästen 32 der Bajonettkonturen 30 ausgerichtet sind. Das Bakenblatt der Bake 10 steht dann unter einem Winkel von 45° verdreht zur Fußplatte 14. In dieser Stellung wird das Fußstück 12 axial in die Steckaufnahme 28 des Adapters 18 eingeführt. Die Bajonettvorsprünge 50 treten in die vertikalen Äste 32 der Bajonettkonturen ein. Wenn das Fußstück 12 dann weiter abwärts bewegt wird, schlagen die Bajonettvorsprünge 50 mit ihrer Unterseite an den unteren Enden der vertikalen Äste 32 der L-förmigen Nuten an. Die Bake 10 und das Fußstück 12 werden dann um ihre vertikale Mittelachse gedreht. Die Bajonettvorsprünge 50 laufen in den horizontalen Ästen 34 der L-förmigen Nuten auf die Rastvorsprünge 37 der Rastfedem 35 auf und drücken diese nach unten. Die Länge der horizontalen Äste 34 ist so bemessen, daß der Drehwinkel auf 45° begrenzt wird.When the foot piece 12 is inserted into the adapter 18 and in that shown in Figure 1 To be locked, the foot piece 12 is first in one such an angular position from above to the adapter 18 that the bayonet projections 50 aligned with the vertical branches 32 of the bayonet contours 30 are. The beacon sheet of the beacon 10 is then at an angle of 45 ° rotated to the base plate 14. In this position, the base piece 12 is axially in the receptacle 28 of the adapter 18 is inserted. The bayonet projections 50 enter the vertical branches 32 of the bayonet contours. If the foot piece 12 is then moved further downward, the bayonet projections 50 strike with it Bottom at the lower ends of the vertical branches 32 of the L-shaped grooves on. The beacon 10 and the foot piece 12 are then about their vertical central axis turned. The bayonet projections 50 run in the horizontal branches 34 the L-shaped grooves on the locking projections 37 of the locking springs 35 and push this down. The length of the horizontal branches 34 is dimensioned that the angle of rotation is limited to 45 °.

Wenn die Bajonettvorsprünge 50 in der in Figur 1 gezeigten Position an den Enden der horizontalen Äste 34 der Nuten anschlagen, sind jeweils beide Rastfedem 35 im wesentlichen entspannt, so daß das Fußstück 12 in der Verriegelungsstellung arretiert wird. In dieser Stellung ist das Fußstück 12 durch die Steckaufnahme 28 und die Bajonettvorsprünge 50 kippsicher in dem Adapter 18 gehalten. Der Flansch 44 des Fußstücks liegt in geringem Abstand oberhalb des Bundes 20 des Adapters und verhindert das Eindringen von Schmutz in die Steckaufnahme 28.When the bayonet protrusions 50 in the position shown in Figure 1 at the ends of the horizontal branches 34 of the grooves, both are detent springs 35 substantially relaxed, so that the foot piece 12 in the locked position is locked. In this position, the foot piece 12 is through the Plug-in receptacle 28 and the bayonet protrusions 50 tilt-proof in the adapter 18 held. The flange 44 of the foot piece is a short distance above the Federal 20 of the adapter and prevents dirt from entering the Plug receptacle 28.

Figur 6 zeigt eine abgewandelte Ausführungsform in einer Darstellung, die Figur 1 entspricht. Hier sind die Rastfedem 35 an den Nuten weiter zur Verriegelungsposition der Bajonettvorsprünge 50 hin angeordnet, so daß jeweils nur die rechte der beiden Rastfedem 35 entspannt ist, wenn die Bajonettvorsprünge 50 in der in Figur 6 gezeigten Position an den Enden der horizontalen Äste 34 der Nuten anschlagen. Die jeweils linke der beiden Rastfedem 35 klemmt dabei den Bajonettvorsprung 50 gegen die Oberseite des horizontalen Astes 34 der Nut.Figure 6 shows a modified embodiment in a representation, the figure 1 corresponds. Here the detent springs 35 are further on the grooves to the locking position the bayonet projections 50 arranged so that only the right one of the two detent springs 35 is relaxed when the bayonet projections 50 in 6 at the ends of the horizontal branches 34 of the grooves attacks. The respective left of the two detent springs 35 clamps the Bayonet projection 50 against the top of the horizontal branch 34 of the groove.
