Description

Die Erfindung bezieht sich auf eine Aufhängung für um etwa 180 Grad schwenkbare, in den vertikalen Seitenwänden von Nutzfahrzeugaufbauten angeordnete Klappen oder dergl., die bei hängender Anordnung in ihrer Schließlage fluchtend in der Seitenwand des Aufbaues einliegen und die in ihrer Öff­nungsendlage zur Seitenwand des Aufbaues wenigstens annähernd parallel gerichtet sind.The invention relates to a suspension for flaps or the like arranged in the vertical side walls of commercial vehicle bodies, which lie in alignment in the closed position in their closed position in the side wall of the body and which are at least in their opening end position to the side wall of the body are directed approximately parallel.

Bei bestimmten Bauarten von Nutzfahrzeugen, vor allem solchen mit geschlossenen Aufbauten, wie beispielsweise Omnibussen sind im unteren Bereich des Aufbaues häufig Stauräume für Ausrüstungsteile oder Gepäck vorgesehen, die ihrerseits durch um horizontale Achsen schwenkbare, in ihrer Schließlage fluch­tend in der Ebene der Aufbauseitenwand einliegende Klappen oder dergl. verschließbar sind. Um eine gute Zugänglichkeit der meist tiefliegend angeordneten Stauräume des Fahrzeugauf­baues zu ermöglichen müssen dabei die diese verschließenden Klappen aus ihrer Schließlage heraus um etwa 180 Grad nach oben schwenkbar am Fahrzeugaufbau angelenkt sein. Aus verschie­denen Gründen, insbesondere aus dem Grund der Unfallsicherheit, aber auch um besonders verschmutzende Stellen am Fahrzeugaufbau zu vermeiden, sind für die Anlenkung solcher Klappen außenlie­gend angeschlagene Scharniere, die eine solche Verschwenkmög­lichkeit ohne weiteres bieten würden unerwünscht oder unzuläs­sig. Eine Anlenkung über gekröpfte innenliegend angeordnete Scharnierarme, wie sie beispielsweise aus dem Karosseriebau bei Personenkraftwagen bekannt ist, ist mit Rücksicht auf die zur Verfügung stehenden Befestigungsmglichkeiten für den Scharnierarm nur schwer und nur mit einem erheblichen techni­schen Aufwand, sowie gegebenenfalls unter Inkaufnahme einer Verringerung des tatsächlich nutzbaren Volumens des jeweiligen Stauraumes realisierbar.In certain types of commercial vehicles, especially those with closed bodies, such as, for example, buses, storage spaces for items of equipment or luggage are often provided in the lower area of the body, which, in turn, are flaps or flaps which are in alignment with the horizontal side of the body and are flush with their closed position the like. are closable. In order to allow easy access to the storage spaces of the vehicle body, which are usually located at a low level, the flaps which close these must be articulated upwards from their closed position and pivotable on the vehicle body. For various reasons, in particular for reasons of accident safety, but also in order to avoid particularly dirty spots on the vehicle body, hinges externally attached for the articulation of such flaps, which would easily offer such a pivoting possibility, are undesirable or inadmissible. A articulation via cranked hinge arms arranged internally, as is known, for example, from body construction in passenger cars, is difficult with regard to the available fastening options for the hinge arm and only with a considerable technical outlay, and possibly with a reduction in the actually usable Volume of the respective storage space realizable.

Der Erfindung liegt daher die Aufgabe zugrunde eine Aufhängung für um etwa 180 Grad schwenkbare, in ihrer Schließlage fluch­tend in der Ebene des Seitenwand des Aufbaues eines Nutzfahr­zeuges einliegende Klappen oder dergl. zu schaffen, die eine leichtgängige Verschwenkbarkeit der Klappe ermöglicht und ohne Rücksicht auf die bauliche Gestaltung des Fahrzeugaufbaues in einfacher Weise an diesem anschlagbar ist und die insbeson­dere eine Verringerung des nutzbaren Volumens des Stauraumes vermeidet und die schließlich eine einfache, mit geringstem Arbeitsaufwand handhabbare Einstellmöglichkeit für die in ihrer Schließlage befindliche Klappe gewährleistet.The invention is therefore based on the object of providing a suspension for flaps or the like which are pivotable in their closed position and are in alignment in the closed position in the plane of the side wall of the body of a commercial vehicle, and which enables the flap to be pivoted easily and without regard to the construction Design of the vehicle body can be attached to it in a simple manner and which, in particular, avoids a reduction in the usable volume of the storage space and which finally ensures a simple adjustment option for the flap located in its closed position which can be handled with the least amount of work.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Klappe sowohl in ihrer Öffnungslage als auch in ihrer Schließ­lage vermittels eines Gelenkhebelparallelogrammes frei tragend in der Öffnung der Seitenwand des Aufbaues gehalten ist, wobei das Gelenkhebelparallelogramm einerseits in deren Stirnbereich an der Klappe und andererseits an einem im Abstand von der vertikalen Außenfläche der Seitenwand des Aufbaues angeordneten Träger angeschlagen ist und wobei das Gelenkhebelparallelogramm eine Vielzahl von um zueinander parallele horizontale Achsen schwenkbar angelenkte Gelenkhebel unterschiedlicher Länge umfasst. Ein solches eine freitragende Aufhängung der Klappe bildendes Gelenkhebelparallelogramm erfordert sowohl an der Klappe als auch am Fahrzeugaufbau nur eine geringe Anschlag­fläche und bietet darüberhinaus den Vorteil, daß seine An­schlagmittel, wie Befestigungskonsole oder Lagerböcke in ein­facher Weise jeder beliebigen vorgegebenen Lage und Ausbildung der aufbau-oder klappenseitigen Anschlagflächen angepasst werden können, wodurch gleichzeitig auch der Arbeitsaufwand für das Anschlagen der Klappe verringert wird. Zusätzlich kann das die freitragende Aufhängung der Klappe bildende Gelenkhebelparallelogramm auch noch mit einer Einstellvorrich­tung zur nachträglichen Ausrichtung der Klappe in eine zur Ebene der Aufbauseitenwand absolut fluchtende Schließlage versehen sein, wobei die Einstellvorrichtung zweckmäßigerweise eine von den Anschlagmitteln des Gelenkparallelogrammes unab­ hängige Justiervorrichtung aufweist. Schließlich resultiert aus der Unabhängigkeit der erfindungsgemäßen freitragenden Aufhängung über ein Gelemnkhebelparallelogramm von der Ausbildung und Anordnung der klappen-oder aufbauseitigen Anschlagflächen auch noch der Vorteil, daß eine Verringerung des nutzbaren Stauraumvolumens durch die Klappenaufhängung weitgehendst ausgeschlossen ist.This object is achieved in that the flap is held freely in the opening of the side wall of the structure both in its open position and in its closed position by means of an articulated lever parallelogram, the articulated lever parallelogram on the one hand in its end region on the flap and on the other hand at a distance is struck by the vertical outer surface of the side wall of the structure and wherein the articulated lever parallelogram comprises a plurality of articulated levers of different lengths articulated about parallel horizontal axes. Such an articulated lever parallelogram forming a self-supporting suspension of the flap requires only a small stop surface both on the flap and on the vehicle body and also offers the advantage that its stop means, such as fastening brackets or pedestals, in a simple manner any given position and design of the body or flap side Abutment surfaces can be adjusted, which at the same time also reduces the workload for attaching the flap. In addition, the articulated lever parallelogram forming the cantilever suspension of the flap can also be provided with an adjusting device for subsequent alignment of the flap in a closed position absolutely flush with the plane of the body side wall, the adjusting device expediently being independent of the sling means of the articulated parallelogram pending adjustment device. Finally, the independence of the self-supporting suspension according to the invention via a articulated lever parallelogram from the design and arrangement of the flap or body-side stop surfaces also results in the advantage that a reduction in the usable storage space volume is largely excluded by the flap suspension.

Die Erfindung kann im Einzelnen auf verschiedene Weisen ausge­staltet werden. Gemäß einer bevorzugten Ausgestaltungsform ist jedoch vorgesehen, daß das Gelenkhebelparallelogramm eine gerade Anzahl, insbesondere vier, untereinander über eine ungerade Anzahl von Gelenken um parallele horizontale Achsen schwenkbar verbundene Gelenkhebel umfasst und daß die Gelenk­hebel eines ersten Gelenkhebelpaares um im Abstand voneinander in einer im flachen Winkel zur Horizontalen geneigten Ebene angeordnete Achsen schwenkbar an einer an einem von der Aufbau­seitenwand beabstandeten Träger angeschlagenen Konsole ange­lenkt und die Gelenkhebel eines zweiten Gelenkhebelpaares über zwei voneinander unabhängige Lagerböcke an zueinander wenigstens annähernd im rechten Winkel ausgerichtenen Flächen ihres Stirnbereiches an der Klappe angelenkt und die beiden einander bei in der der Schließlage der Klappe entsprechenden Stellung befindlichem Gelenkhebelparallelogramm gegenüberlie­genden Gelenkhebel über ein zusätzliches im Abstand zu ihren beiden Enden angeordnetes Gelenk miteinander gekoppelt sind.The invention can be designed in various ways in detail. According to a preferred embodiment, however, it is provided that the articulated lever parallelogram comprises an even number, in particular four, articulated levers pivotally connected to one another via an odd number of articulations about parallel horizontal axes, and that the articulated levers of a first pair of articulated levers are spaced apart from one another at a flat angle Horizontal inclined planes arranged pivotably articulated on a bracket attached to a support spaced from the side wall of the body and the articulated levers of a second pair of articulated levers articulated via two mutually independent bearing brackets to surfaces of their forehead area which are at least approximately at right angles to one another and the two at in the articulated lever parallelogram opposite the position corresponding to the closed position of the flap, articulated lever opposite one another via an additional articulated joint spaced from its two ends g are decoupled.

Vorteilhaft sind dabei die Anlenkachsen des zweiten Gelenkhe­belpaares an der Klappe in einer in einem flachen Winkel zur Vertikalen ausgerichteten Ebene angeordnet und ist der Anstell­winkel der Ebene in der das erste Gelenkhebelpaar angelenkt ist zur Horizontalen wenigstens annähernd gleich groß ist wie der Anstellwinkel der Ebene in der das zweite Gelenkhebel­paar angelenkt ist zur Vertikalen. Dadurch kann unabhängig von der jeweiligen Ausrichtung und Lage der Anschlagflächen am Aufbau oder an der Klappe eine bis auf die Ausbildung der Befestigungskonsole bzw. der Lagerböcke einheitliche Ausfüh­ rungsform des Gelenkhebelparallelogrammes für alle vorkommenden Einbauverhältnisse angewandt werden. In diesem Zusammenhang ist es weiterhin vorteilhaft, daß die Gelenkhebel des zweiten Gelenkhebelpaares quer zu ihrer Längserstreckung geknickt ausgebildet sind.The articulation axes of the second pair of articulated levers on the flap are advantageously arranged in a plane oriented at a flat angle to the vertical and the angle of attack of the plane in which the first pair of articulated levers is articulated to the horizontal is at least approximately the same as the angle of incidence of the plane in which second pair of articulated levers is articulated to the vertical. As a result, regardless of the respective orientation and position of the stop faces on the body or on the flap, a design which is uniform except for the design of the fastening bracket or of the bearing blocks can be achieved form of the articulated lever parallelogram can be used for all existing installation conditions. In this context, it is also advantageous that the articulated levers of the second pair of articulated levers are designed to be kinked transversely to their longitudinal extent.

Eine besonders einfachache Ausbildung einer Einstellmöglichkeit für die Justierung der Klappe in ihrer zur Aufbauseitenwand fluchtenden Lage kennzeichnet sich dadurch, daß die Einstell­einrichtung einen an der inneren Stirnseite der Konsole ange­ordneten Anschlag und eine eine über dessen Anlenkung hinausra­gende Verängerung des in Bezug auf den Aufbau innenliegenden Gelenkhebels des ersten Gelenkhebelpaares durchsetzende Stell­schraube umfasst.A particularly simple design of an adjustment option for the adjustment of the flap in its position aligned with the body side wall is characterized in that the adjusting device has a stop arranged on the inner end face of the console and a protrusion extending beyond the articulation of the inner articulated lever of the body includes first set of articulated levers passing through.

Eine die Schließlage der Klappe definierender Schließendan­schlag ist in besonders vorteilhafter Weise dadurch ausgebil­det, daß der die Schließendlage der Klappe definierende Endan­schlag durch eine zwei aufeinander senkrecht stehende Flächen­abschnitte umfassende und mit der innenliegenden Oberkante der Klappe zusammenwirkende Einkerbung im innenliegenden Ge­lenkhebel des zweiten Gelenkhebelpaares gebildet ist.A closing end stop defining the closed position of the flap is formed in a particularly advantageous manner in that the end stop defining the closing end position of the flap is formed by a notch in the inner articulated lever of the second pair of articulated levers, comprising two mutually perpendicular surface sections and interacting with the inner upper edge of the flap.

Für Klappen mit geringerer Längenausdehnung kann hierbei die Anordnung eines einzigen Gelenkhebelparallelogrammes mit doppelten horizontalen im Abstand voneinander angeordneten und durch die Gelenkachsenausbildung untereinander verbundenen Gelenkhebeln genügen, während für Klappen größerer Längenaus­dehnung die Anordnung wenigstens zweier Gelenkehebelparallelo­gramme vorgesehen ist.For flaps with a smaller linear expansion, the arrangement of a single articulated lever parallelogram with double horizontal articulated levers spaced apart and interconnected by the articulation of the articulated axes can suffice, while for flaps with a larger linear expansion, the arrangement of at least two articulated lever parallelograms is provided.

Die Erfindung ist in der nachfolgenden Beispielsbeschreibung anhand eines in der Zeichnung dargestellten Ausführungsbeispie­les im Einzelnen beschrieben.The invention is described in detail in the following example description using an exemplary embodiment shown in the drawing.

In der Zeichnung zeigt die einzige Figur eine Seitenansicht einer erfindungsgemäßen Klappenaufhängung, wobei die der Öff­ nungsendlage der Klappe zugeordnete Stellung des Gelenkhebelpa­rallelogrammes in gestrichelten Linien eingezeichnet ist.In the drawing, the single figure shows a side view of a flap suspension according to the invention, the opening of the End position of the flap assigned position of the articulated lever parallelogram is shown in dashed lines.

Eine in ihrer Schließendlage fluchtend in der Seitenwand 1 eines in der Zeichnung nur ausschnittweise dargestellten Fahr­zeugaufbaues einliegende Klappe 2 ist in hängender Anordnung über ein Gelenkhebelparallelogramm 3 freitragend an einem zur Aufbauseitenwand zum Aufbauinneren hin beabstandet belege­nen Träger 4 des Fahrzeugaufbaues aufgehängt. Das Gelenkhebel­parallelogramm 3 umfasst dabei zwei Paare von Gelenkhebeln 5,6 und 7,8, wobei die Gelenkhebel 5 und 6 des ersten Gelenk­hebelpaares an einer vermittels Scharauben 9 am Träger 4 ange­schlagenen Konsole 10 um zueinander parallele, voeinander beabstandete Achsen 11, 12 angelenkt sind. Die Anlenkachsen 11 und 12 der Gelenkhebel 5 und 6 des ersten Gelenkhebelpaares sind dabei in einer in einem flachen Winkel a zur Horizontalen geneigten Ebene angeordnet. Die Gelenkhebel 5 und 6 des ersten Gelenkhebelpaares sind an ihren freien Enden über Gelenke 13 und 14 um parallele horizontale Achsen schwenkbar mit den Gelenkhebeln 7 und 8 des zweiten Gelenkhebelpaares verbunden. Die Gelenkhebel 7 und 8 des zweiten Gelenkhebelpaares sind quer zu ihrer Längserstreckung mit jeweils einer Abknickung 15 versehen und an ihren freien Enden über Gelenke 16 und 17 um parallele horizontale Achsen schwenkbar an Lagerböcken 19 und 20 angelenkt, wobei die Lagerböcke 19 und 20 voneinander unabhängig ausgebildet und über Befestigungsschrauben 21 an aufeinander senkrecht stehenden Flächenbereichen 22 und 23 des Stirnbereiches der Klappe 2 angeschlagen sind. Die Ausbil­dung der Lagerböcke 19 und 20 ist dabei mit Rücksicht auf ihre vorbestimmte Anschlaglage an der Klappe 2 derart getrof­fen, daß die Achsen der die Gelenkhebel 7 und 8 des zweiten Gelenkhebelpaares mit den Lagerböcken 19 und 20 verbindenden Gelenke 16 und 17 in einer mit der Vertikalen einen flachen Winkel b einschließenden Ebene liegen. Der Anstellwinkel b zur Vertikalen ist dabei gleich groß bemessen wie der Anstell­winkel a der Anordnungsebene der Gelenkachsen der Gelenke 11 und 12 des ersten Gelenkhebelpaares zur Horizontalen. Die beiden in Bezug auf das Gelenkparallelogramm 3 innenliegenden und bei in der Schließlage der Klappe 2 einander kreuzenden Gelenkhebel 6 und 7 beider Gelenkhebelpaare sind über ein zusätzliches, im Abstand von ihren jeweiligen freien Enden angeordnetes Gelenk 24 um eine zu den übrigen Gelenkachsen des Gelenkhebelparallelogrammes 3 parallele Achse untereinander gekoppelt. Zur Bildung eines die Schließendlage der Klappe 2 definierenden Endanschlages ist der innenliegende Gelenkhebel 7 des zweiten Gelenkhebelpaares mit einer durch zwei aufeinan­der senkrecht stehende Flächen 26,27 gebildeten Einkerbung 28 versehen, über die er bei in der Schließendlage befindlicher Klappe 2 mit einer Ecke 29 des sie bildenden Hohlkörpers in formschlüssigen Eingriff gelangt. Eine der Einjustierung der Klappe 2 in ihre zur Ebene der Aufbauseitenwand 1 fluchtende Lage dienende Einstellvorrichtung 30 ist im gezeigten Ausfüh­rungsbeispiel durch einen mittels einer Abstellung 31 am innen­liegenden Ende der Konsole 10 gebildeten Anschlag und eine an diesem zur Anlage kommende Einstellschraube 32 gebildet, wobei die Einstellschraube 32 eine diesem gegenüber abgewin­kelte, über das Gelenk 11 hinausreichende Verlängerung 33 des innenliegenden Gelenkhebels 5 des ersten Gelenkhebelpaares durchgreift und an der Verlängerung 33 mittels einer Gegen­mutter 34 in der jeweils gewählten Einstellage festlegbar ist.A flap 2 lying in its closed end position in alignment in the side wall 1 of a vehicle body shown only in detail in the drawing is suspended in a hanging arrangement via a articulated lever parallelogram 3 cantilevered on a carrier 4 of the vehicle body which is spaced apart from the body side wall from the interior of the body. The articulated lever parallelogram 3 comprises two pairs of articulated levers 5, 6 and 7, 8, the articulated levers 5 and 6 of the first articulated lever pair being articulated on a bracket 10 attached to the carrier 4 by means of screw bolts 9 about mutually parallel axes 11, 12 spaced apart from one another. The articulation axes 11 and 12 of the articulated levers 5 and 6 of the first articulated lever pair are arranged in a plane inclined at a flat angle a to the horizontal. The articulated levers 5 and 6 of the first articulated lever pair are connected at their free ends to the articulated levers 7 and 8 of the second articulated lever pair via articulations 13 and 14 so that they can pivot about parallel horizontal axes. The articulated levers 7 and 8 of the second pair of articulated levers are each provided with a bend 15 transversely to their longitudinal extent and pivoted at their free ends via articulations 16 and 17 about parallel horizontal axes to bearing blocks 19 and 20, the bearing blocks 19 and 20 being formed independently of one another and are attached by fastening screws 21 to mutually perpendicular surface areas 22 and 23 of the end area of the flap 2. The design of the pedestals 19 and 20 is made with regard to their predetermined stop position on the flap 2 such that the axes of the articulated levers 7 and 8 of the second pair of articulated levers connecting the pedestals 19 and 20 joints 16 and 17 in one with the vertical a plane including a flat angle b. The angle of attack b to the vertical is dimensioned the same as the angle of attack a of the plane of arrangement of the articulation axes of the joints 11 and 12 of the first pair of articulated levers to the horizontal.
