Abstract

There is a panel in which a carrier plate (2) and a backing plate (1) are combined and in which detachable connecting devices (16, 19) are provided in the corner areas only for connecting the carrier plate (2) and the backing plate (1). In this context it is wished to make the fixed connections in the corner areas of outwardly concealed design without the use of screws. This is achieved in that each connecting device is formed from a sleeve (16) and a spigot (19) firmly wedged therein, which form an integral part of the carrier plate (2) on the one hand and the backing plate (1) on the other. These sleeve-spigot connections are invisible from outside, making it difficult for the uninformed person to detach them. <IMAGE>

Description

Die Erfindung betrifft ein Schild, bei dem eine Trägerplatte und eine Rückplatte zusammengesetz und mit Durchgangslöchern für mindestens eine durchzusteckende Befestigungsschraube mit Kopf versehen sind, bei dem die Trägerplatte Fenster und diese überquerende Querstege, die mit dem Fensterrand Schlitze begrenzen, aufweist, bei dem in die Fenster Felder gesetzt sind, die mit federnd biegbaren Schenkeln durch die Schlitze greifen und den Schlitzrand hintergreifen, bei dem an der Rückplatte Rippen vorgesehen sind, die in die Schlitze eben die Schenkel ragen, bei dem die Trägerplatte bei dem Durchgangsloch über einen Abstützvorsprung gegen die Rückplatte abgestützt ist und bei dem die mindestens eine Befestigungsschraube hinter dem Schild an einer Trageinrichtung angreift sowie an den Eckbereichen lösbare Verbindungseinrichtungen nur zur Verbindung von Trägerplatte und Rückplatte vorgesehen sind.The invention relates to a sign in which a support plate and a back plate are put together and are provided with through-holes for at least one fastening screw to be inserted with a head, in which the support plate has windows and transverse webs crossing these, which delimit slots with the window edge, in which in the Window fields are set, which reach through the slots with resiliently bendable legs and reach behind the edge of the slot, in which ribs are provided on the back plate, which project into the slots in the legs, in which the support plate at the through hole via a support projection against the back plate is supported and in which the at least one fastening screw engages behind the shield on a support device and releasable connection devices are provided at the corner regions only for connecting the support plate and the back plate.

Das Schild gibt z.B. Hinweise auf die Lage von Wasser- oder Kanalisationsanschlüssen an Straßen. Bei einem bekannten (DE-B-1 099 334) Schild dieser Art sind die Verbindungseinrichtungen in den Eckbereichen Befestigungsschrauben und Muttern, wobei die Schraubenköpfe von vorne ohne weiteres zugänglich sind und die Verbindungseinrichtungen unerlaubterweise von nichtsachkundigen leicht gelöst werden können. Auch sind vier Schrauben mit Muttern nötig.For example, the sign gives information about the location of water or sewage connections on roads. In a known (DE-B-1 099 334) shield of this type, the connecting devices in the corner areas are fastening screws and nuts, the screw heads being easily accessible from the front and the connecting devices being unauthorized and easy to remove by unauthorized persons. Four screws with nuts are also required.

Nach der DE-A-2 818 798 werden Rastzungen benützt, welche durch Schlitze hindurch mit einem Werkzeug entriegelt werden können. Die Befestigungsschrauben zur Trageinrichtung hin sind verdeckt. Eine unerlaubte Demontage ist somit erschwert. Sie bleibt aber, unter Zuhilfenahme eines spitzen Gegenstandes, möglich. Es ist somit die Aufgabe der Erfindung ein Schild dieser Art zu schaffen wobei eine unerlaubte Demontage weiter erschwert ist.According to DE-A-2 818 798 locking tongues are used which can be unlocked through slots with a tool. The fastening screws to the carrying device are covered. Unauthorized disassembly is therefore difficult. However, it remains possible with the help of a pointed object. It is therefore the object of the invention to provide a shield of this type, which makes unauthorized disassembly even more difficult.

Das erfindungsgemäße Schild ist, diese Aufgabe lösend, dadurch gekennzeichnet, daß jede Verbindungseinrichtung von einer Muffe und einem darin klemmend festsitzenden Zapfen gebildet ist, die einerseits mit der Trägerplatte und andererseits mit der Rückplatte einstückig sind.The shield according to the invention is solving this problem, characterized in that each connecting device is formed by a sleeve and a pin which is fixedly clamped therein and which, on the one hand, is integral with the carrier plate and, on the other hand, with the rear plate.

Diese Muffe-Zapfen-Verbindungen sind von außen nicht sichtbar, so daß ihre Lösung dem Nicht-Sachkundigen erschwert ist. Der Sachkundige kann die Muffe-Zapfen-Verbindung des von der Trageinrichtung abgenommenen Schildes unter erheblicher Kraftaufwendung mittels eines Werkzeuges lösen. Es sind Schraubeinrichtungen vermieden und Muffe und Zapfen werden beim Herstellen der Trägerplatte und der Rückplatte mit angeformt.These socket-pin connections are not visible from the outside, so that their solution is difficult for the non-expert. The person skilled in the art can loosen the socket-spigot connection of the plate removed from the carrying device with considerable force using a tool. Screwing devices are avoided, and the socket and spigot are also formed when the carrier plate and the back plate are manufactured.

Der Preßsitz des Zapfens in der Muffe läßt sich erreichen, indem der Durchmesser des Zapfens etwas größer gewählt wird als der Innendurchmesser der Muffe. Da dies toleranzenfreie Herstellung verlangt, ist es besonders zweckmäßig und vorteilhaft, wenn zwischen Muffe und Zapfen längsverlaufende angeformte Rippen geringen Querschnittes vorgesehen sind. Die Rippen gleichen Toleranzen aus und vermitteln den festen Sitz des an sich die Muffe nicht berührenden Zapfens. Die Rippen werden beim Einpressen des Zapfens verformt und geben so einen sehr festen, aber doch lösbaren Reibschluß zwischen Zapfen und Muffe.The press fit of the pin in the sleeve can be achieved by choosing the diameter of the pin slightly larger than the inside diameter of the sleeve. Since this requires tolerance-free production, it is particularly expedient and advantageous if longitudinally formed molded-on ribs of small cross-section are provided between the sleeve and the pin. The ribs equalize tolerances and convey the tight fit of the spigot, which does not actually touch the socket. The ribs are deformed when the pin is pressed in and thus give a very firm, yet releasable frictional connection between the pin and the sleeve.

Besonders zweckmäßig und vorteilhaft ist es dabei, wenn vier Rippen über den Umfang verteilt sind. Die Verbindung zwischen Zapfen und Muffe ist bei drei Rippen häufig nicht sehr fest und eine fünfte Rippe ist überflüssig.It is particularly expedient and advantageous if four ribs are distributed over the circumference. The connection between the spigot and the socket is often not very tight with three ribs and a fifth rib is superfluous.

Besonders zweckmäßig und vorteilhaft ist es ebenfalls, wenn Trägerplatte und Rückplatte bei jeder Verbindungseinrichtung einen Durchbruch aufweisen und wenn der Zapfen mit einer axialen Bohrung versehen ist, welche die beiden Durchbrüche verbindet. Es läßt sich durch die Muffe-Zapfen-Verbindung eine Befestigungsschraube stecken, um das Schild an einer Trageinrichtung anzubringen.It is also particularly expedient and advantageous if the carrier plate and back plate are in each case Connecting device have an opening and if the pin is provided with an axial bore which connects the two openings. A fastening screw can be inserted through the socket-spigot connection in order to attach the sign to a carrying device.

Besonders zweckmäßig und vorteilhaft ist es dabei, wenn der Durchbruch der Trägerplatte zu deren Außenseite hin von einer in der Dicke verminderten Querwand abgesperrt ist. Die Querwand gibt dem Schild nach außen einen geschlossenen Eindruck und läßt sich für den Einsatz von Befestigungsschrauben leicht herausbohren.

Das Schild gemäß Zeichnung ist aus einem thermoplastischen Kunststoff durch Spritzgießen hergestellt und besitzt eine Rückplatte (1), eine Trägerplatte (2), nicht gezeigte Felder, zwei nicht gezeigte Befestigungsschrauben sowie eine nicht gezeigte Trageinrichtung, die als U-förmiger Bügel ausgebildet ist, der einen vertikalen Pfosten quert, der zwischen den Bügel-Schenkeln angeordnet ist, in welche die Befestigungsschrauben geschraubt sind. Die Trägerplatte (2) weist verschieden große rechteckige Fenster (3) auf, in welche die nicht gezeigten Felder gesetzt werden, die nach vorne hin mit Zeichen versehen sind und nach hinten zwei rechtwinkelig wegragende Schenkel tragen, die an den freien Enden je eine stufenartig vorspringende Rastnase tragen. Jedes Fenster (3) begrenzt mit zwei einander gegenüberliegenden Rändern einen Schlitz (4) und jedes Feld wird mit den beiden Schenkeln durch die beiden Schlitze (4) eines Fensters (3) geschoben, wobei die Nasen hinter die beiden die Schlitze begrenzenden Fenster-Ränder einschnappend greifen.The shield according to the drawing is made of a thermoplastic material by injection molding and has a back plate (1), a carrier plate (2), fields, not shown, two fastening screws, not shown, and a support device, not shown, which is designed as a U-shaped bracket which crosses a vertical post, which is arranged between the bracket legs, in which the fastening screws are screwed. The support plate (2) has rectangular windows (3) of different sizes, in which the fields (not shown) are placed, which are provided with signs towards the front and have two legs projecting at right angles to the rear, each of which has a step-like protrusion at the free ends Wear latch. Each window (3) delimits a slot (4) with two opposite edges and each field is pushed with the two legs through the two slots (4) of a window (3), the lugs behind the two window edges delimiting the slots grasping.

An der Rückseite der Trägerplatte (2) ist außen randseitig ein umlaufender Sims (5) vorgesehen, auf dem die angebaute Rückplatte aufliegt, und ist um jedes Fenster (3) verlaufend ein Sims (6) vorgesehen, dessen Höhe rechtwinkelig zur Trägerplatte kleiner ist als die des randseitigen Simses (5). Jedes Fenster (3) ist von mindestens einem mit der Trägerplatte (2) einstückigen Quersteg (7) überspannt, der von der Vorderseite der Trägerplatte einen der Dicke des Fensters entsprechenden Abstand aufweist und rückseitig beim Schlitz (4) einen verstärkenden Sims (8) trägt. Jedem Schlitz (4) ist - bis auf eine weiter unten geschilderte Ausnahme - eine Rippe (9) zugeordnet. Die schmalen, länglichen Rippen (9) sind an der Rückplatte (1) einstückig mit dieser vorgesehen und ragen bei angebauter Rückplatte in die Schlitze (4) jeweils zwischen Quersteg (7) und Schenkel eines eingesetzten Feldes.On the back of the carrier plate (2), a peripheral ledge (5) is provided on the outside, on which the attached rear plate rests, and a ledge (6) is provided around each window (3), the height of which is perpendicular to the carrier plate is less than the edge of the ledge (5). Each window (3) is spanned by at least one cross piece (7) which is integral with the support plate (2) and which is at a distance corresponding to the thickness of the window from the front of the support plate and carries a reinforcing ledge (8) at the back of the slot (4) . With the exception of an exception described below, each slot (4) is assigned a rib (9). The narrow, elongated ribs (9) are provided in one piece on the back plate (1) and, when the back plate is attached, protrude into the slots (4) between the crosspiece (7) and the leg of an inserted field.

Im Mittenbereich der Trägerplatte (2) sind die Querstege (7) von nur zwei Fenster (3) jeweils mit einem Durchgangsloch (10) versehen, das sich auch auf einen ringartigen Abstützvorsprung (11) erstreckt, der rückseitig von der Trägerplatte mit der gleichen Höhe wie der randseitige Sims (5) wegragt. Das Durchgangsloch (10) ist im Bereich des Quersteges (7) als im Durchmesser größere Ansenkung (12) zur Aufnahme eines Schraubenkopfes ausgebildet und weist im Abstützvorsprung (11) den dem Schraubenschaft zuzuordnenden Durchmesser auf. Der Abstand jedes Durchgangsloches (10) von der seitlichen Außenkante der Trägerplatte (2) ist größer als ein Drittel und nur wenig kleiner als die Hälfte des Abstandes der beiden Durchgangslöcher (10) voneinander. Die Lage der Durchgangslöcher (10) ist auf die als U-Bügel ausgebildete Trageinrichtung abgestellt. Jedem Durchgangsloch (10) der Trägerplatte (2) ist ein Durchgangsloch (13) der Rückplatte (1) zugeordnet. Wie Fig. 5 zeigt sind an den den Durchgangslöchern (13) zugeordneten Stellen (14), denen an sich Rippen zur Feld-Sicherung zuzuordnen sind, keine Rippen vorgesehen. In Fig. 3 ist eine Befestigungsschraube (22) mit einem Kopf (23) angedeutet.In the central area of the carrier plate (2), the crossbars (7) of only two windows (3) are each provided with a through hole (10) which also extends to an annular support projection (11). which protrudes from the back of the carrier plate at the same height as the ledge (5) on the edge. The through hole (10) in the area of the crossbar (7) is designed as a larger diameter (12) for receiving a screw head and has in the support projection (11) the diameter to be assigned to the screw shank. The distance of each through hole (10) from the lateral outer edge of the carrier plate (2) is greater than a third and only slightly less than half the distance between the two through holes (10) from each other. The position of the through holes (10) is placed on the support device designed as a U-bracket. Each through hole (10) of the carrier plate (2) is assigned a through hole (13) of the back plate (1). As FIG. 5 shows, no ribs are provided at the points (14) assigned to the through holes (13), to which ribs are to be assigned to secure the field. In Fig. 3, a fastening screw (22) with a head (23) is indicated.

Die Trägerplatte (2) weist vier Eckbereiche (15) auf, in denen jeweils auf der der Rückplatte (1) zugewandten Seite eine Muffe (16) angeformt ist. Die Muffe (16) besitzt einen Innendurchmesser, der größer ist als der eines Durchbruches (17), der von der Muffe umschlossen in der Trägerplatte vorgesehen ist und der zur Vorderseite der Trägerplatte hin von einer relativ dünnen, membranartige Querwand (18) abgedeckt ist. Die Höhe der Muffe (16) rechtwinkelig zur Trägerplatte (2) ist ebenso groß wie die des randseitigen Simses (5). Die Rückplatte (1) weist auf der Seite der Rippen (9) in den Eckbereichen (15) je einen Zapfen (19) auf, der mit einer durch die Rückplatte hindurchgehenden axialen Bohrung (20) versehen ist, die bei angebauter Rückplatte mit dem Durchbruch (17) fluchtet. Der Außendurchmesser des im Querschnitt kreisrunden Zapfens (19) ist um ein Spiel kleiner als der Innendurchmesser der innen im Querschnitt kreisrunden Muffe (16). Jedoch weist der Zapfen (19) außen um den Umfang herum gleichmäßig verteilt vier Rippen (21) auf, die mit Abstand vom freien Ende des Zapfens (19) enden und von denen in Fig. 7 nur zwei gezeigt sind. Die Rippen (21) sind im Querschnitt sehr klein, füllen das zuletzt erwähnte Spiel aus und sind in radialer Richtung so groß, daß die aufgeschobene Muffe (16) stramm und fest auf dem Zapfen sitzt.The carrier plate (2) has four corner areas (15), in each of which a sleeve (16) is formed on the side facing the rear plate (1). The sleeve (16) has an inner diameter which is larger than that of an opening (17) which is provided in the carrier plate and is covered by the sleeve and which is covered towards the front of the carrier plate by a relatively thin, membrane-like transverse wall (18). The height of the sleeve (16) at right angles to the support plate (2) is the same as that of the ledge (5) on the edge. The back plate (1) has on the side of the ribs (9) in the corner regions (15) each a pin (19) which is provided with an axial bore (20) passing through the back plate, which with the back plate attached has the opening (17) is aligned. The outside diameter of the pin (19), which is circular in cross section, is around one Clearance smaller than the inside diameter of the sleeve (16), which is circular on the inside in cross section. However, the pin (19) has four ribs (21) distributed uniformly on the outside around the circumference, which end at a distance from the free end of the pin (19) and of which only two are shown in FIG. 7. The ribs (21) are very small in cross section, fill the last-mentioned game and are so large in the radial direction that the pushed-on sleeve (16) sits tightly and firmly on the pin.
