Description
Die Erfindung betrifft ein aushängbares Türscharnier nach dem Oberbegriff des Anspruchs 1.The invention relates to a detachable door hinge according to the preamble of claim 1.
Aushängbare Türscharniere werden in der modernen Serienproduktion
von Kraftfahrzeugen angewandt, um die Türen bereits in
deren Rohbau in die Karosserie einpassen und einjustieren und
sie dann während der Montage und Ausrüstung des Fahrzeuges von
der Karosserie abnehmen zu können, was dadurch erreicht wird,
daß einerseits beide Hälften der Türscharniere am jeweiligen
Türanordnungsteil Tür oder Türholm in einer solchen Lage angebracht
und unverrückbar befestigt sind, so daß beim erneuten
Einsetzen der Tür in die Fahrzeugkarosserie die Tür zum Türausschnitt
der Karosserie exakt fluchtend eingepaßt ist. Eine
solche vorübergehende Abnehmbarkeit der Türen bringt einerseits
den Vorteil mit sich, daß die Türen in gesonderten Arbeitsbereichen
aufgarniert werden können, andererseits wird zugleich der
Vorteil erreicht, daß die Montage und die Ausrüstung des Fahrzeuges
bei abgenommenen Türen wesentlich rascher und leichter
durchzuführen ist.
Unbeschadet des hieraus resultierenden Erfordernisses einer
Trennbarkeit, insbesondere Aushängbarkeit, der Türscharniere
besteht jedoch im modernen Kraftwagenbau die Notwendigkeit, eine
dauerhaft absolut wartungsfreien Gestaltung der Scharnierlagerung
zu gewährleisten.
Für die Gestaltung eines aushängbaren Türscharnieres der eingangs
genannten Bauart ist daher bereits vorgeschlagen worden,
daß der Scharnierstift mit dem aufsteckbaren Scharnierauge über
eine mit diesem formschlüssig in Eingriff gelangende Profilierung
mindestens eines Teiles seiner Länge drehsicher verbunden
ist, wobei jeweils der Scharnierstift und das Scharnierauge der
aushängbaren Scharnierhälfte wenigstens über einen Teil ihrer
Länge hin mit axial gerichteten, radial verlaufenden, wechselweise
angeordneten und ineinander greifenden Vorsprüngen und
Vertiefungen versehen sind, insbesondere in der Weise, daß der
in der einen Scharnierhälfte drehbar gelagerte Scharnierstift
mit einem radial ausladenden, die obere Stirnfläche des Scharnierauges
der einen Scharnierhälfte übergreifenden Bund versehen
ist, der an seiner Oberseite mit axial gerichteten Rippen und
Rillen bzw. Vorsprüngen und Vertiefungen versehen ist, welchen
eine gleichartige axial gerichtete Profilierung in der Stirnfläche
des Scharnierauges der anderen Scharnierhälfte zugeordnet
ist. Eine solche Scharniergestaltung gestattet es den Scharnierstift
einerseits dauerhaft wartungsfrei in der einen Scharnierhälfte
zu lagern und ihn im Zuge des Einhängens der Türe gleichzeitig
auch drehsicher mit der anderen Scharnierhälfte zu koppeln,
so daß sicher gestellt ist, daß sich der Scharnierstift
beim Öffnen und Schließen der Türe ausschließlich in der wartungsfreien
Lagerung dreht.
Diese bekannten Ausbildungen aushängbarer Scharniere zeichnen
sich, von mehr oder minder geringfügigen Abwandlungen abgesehen,
übereinstimmend dadurch aus, daß der radial ausladende, die
obere Stirnfläche des Scharnierauges der einen Scharnierhälfte
übergreifende, an seiner Oberseite mit einer axial gerichteten
schräg zur Scharnierachse gerichteten konischen Ausrichtfläche
versehene Bund mit dem Scharnierstift einteilig ausgebildet ist.
Aus dieser einteiligen Ausbildung von Scharnierstift und konischer
Ausrichtfläche bzw. diese tragendem Bund resultieren in
manchen Fällen, insbesondere dann, wenn eine Vormontage des-Scharnieres
mit weiteren Anbauteilen, wie z.B. einem aufgesetzten
Türfeststeller, erforderlich ist, Schwierigkeiten, da eine
Montage im Wege eines Einführens des Schnierstiftes durch das
Scharnierauge der nicht aushängbaren Scharnierhälfte infolge der
radialen Ausladung des Bundes bzw. der an diesem ausgebildeten
konischen Ausrichtfläche nicht möglich ist. Aber auch bei der
Montage eines einfachen aushängbaren Scharnieres bringt die mit
dem Scharnierstift einteilige Ausbildung von konischer Ausrichtfläche
bzw. diese tragendem Bund gewisse Nachteile mit
sich, insbesondere dahingehend, als der Scharnierstift in einem
besonderen Arbeitsgang und unter Einsatz einer zusätzlichen
Sicherungsplatte oder dergl. gegenüber dem Scharnierauge derjenigen
Scharnierhälfte, in welcher er bleiben und mit Laufsitz
gelagert ist, gegen ein Wandern in axialer Richtung gesichert
werden muß. Detachable door hinges are used in modern series production of motor vehicles in order to fit and adjust the body of the door in the body and adjust it and then to be able to remove it from the body during assembly and equipping of the vehicle, which is achieved in that on the one hand both halves the door hinges are attached to the respective door arrangement part door or door spar in such a position and fixed immovably, so that when the door is reinserted into the vehicle body, the door to the door cutout of the body is fitted exactly in alignment. Such a temporary detachability of the doors has the advantage that the doors can be garnished in separate work areas, on the other hand, the advantage is achieved that the assembly and equipment of the vehicle can be carried out much faster and easier with the doors removed.
Notwithstanding the resultant requirement for separability, in particular detachability, of door hinges, however, in modern motor vehicle construction there is a need to ensure that the hinge mounting is permanently maintenance-free.
For the design of a detachable door hinge of the type mentioned at the outset, it has therefore already been proposed that the hinge pin be connected in a rotationally secure manner to the attachable hinge eye via a profiling which engages with it in a form-fitting manner, at least a part of its length, the hinge pin and the hinge eye of the detachable each Hinge half are provided at least over part of their length with axially directed, radially extending, alternately arranged and interlocking projections and depressions, in particular in such a way that the hinge pin, which is rotatably mounted in one hinge half, has a radially protruding, the upper end face of the hinge eye the one hinge half overlapping collar is provided, which is provided on its upper side with axially directed ribs and grooves or projections and depressions, which have a similar axially directed profile is assigned to the other hinge half in the end face of the hinge eye. Such a hinge design allows the hinge pin to be permanently maintenance-free stored in one hinge half and coupled with the other hinge half in the course of hanging the door, so that it is ensured that the hinge pin opens and closes when the door is opened and closed rotates exclusively in the maintenance-free storage.
These known designs of detachable hinges are distinguished, apart from more or less minor modifications, in that the radially protruding collar, which overlaps the upper end face of the hinge eye of one hinge half, is provided on its upper side with an axially directed conical alignment surface directed obliquely to the hinge axis is formed in one piece with the hinge pin. Difficulties arise from this one-piece design of the hinge pin and the conical alignment surface or this supporting collar, in particular when the hinge needs to be preassembled with further add-on parts, such as an attached door arrester, because assembly by means of insertion of the Schnierstiftes through the hinge eye of the non-detachable hinge half due to the radial projection of the federal government or the conical alignment surface formed on this is not possible. But even when installing a simple detachable hinge, the one-piece design of the conical alignment surface or the collar that carries this hinge pin has certain disadvantages, in particular in that the hinge pin in a special operation and using an additional securing plate or the like The hinge eye of the hinge half in which it remains and is mounted with a running seat must be secured against wandering in the axial direction.
DE-U-297 04 055 beschreibt ein aushängbares Kraftwagentürscharnier, bei dem ein Scharnierstift mit Laufsitz in einer ersten Schamierhälfte und drehfest in einer zweiten, aushebbaren Scharnierhälfte vorgesehen ist, wobei ein Außengewinde des Scharnierstifts ein Überwerfen einer Konusmutter ermöglicht, deren Konus mit einem entsprechend ausgebildeten Konus der zweiten Scharnierhälfte zusammengreift, wobei der Schamierstift ferner einen Bund mit einem konusförmigen Absatz aufweist, der mit einem weiteren Konus der zweiten Scharnierhälfte zusammenwirkt.DE-U-297 04 055 describes a detachable motor vehicle door hinge, at a hinge pin with a seat in the first half of the hinge and non-rotatable is provided in a second, removable half hinge, one Male thread of the hinge pin is a union nut enables the cone with a suitably trained cone second hinge half engages, the hinge pin also a Has a collar with a cone-shaped heel with another cone the second half of the hinge interacts.
Es ist die Aufgabe der Erfindung, ein Türscharnier nach dem Oberbegriff des Anspruchs 1 anzugeben, welches die Montage des Scharnierstifts an der nicht aushängbaren Scharnierhälfte vereinfacht und zugleich die Vormontage des Scharniers mit weiteren Anbauteilen ermöglicht.It is the object of the invention to provide a door hinge according to the preamble of Claim 1 to specify which the assembly of the hinge pin on the detachable hinge half simplified and at the same time the pre-assembly of the Hinge with additional attachments.
Diese Aufgabe wird bei dem eingangs genannten Türscharnier erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.This task is performed with the door hinge mentioned at the beginning according to the invention with the characterizing features of claim 1 solved.
Die Trennung des eigentlichen Scharnierstifts und des radial ausladenden, die konische Ausrichtfläche tragenden Bundes in zwei eigenständige und jeweils als eigenständiges Teil montierbare Teile führt zunächst dazu, daß der Scharnierstift durch das Scharnierauge derjenigen Scharnierhälfte, in welcher er mit Laufsitz gelagert ist, in das Scharnier und gegebenenfalls im Weiteren in ein Anbauteil, wie einen Türfeststeller, eingeführt werden kann, wodurch die Vormontage von Scharnier und Anbauteil wesentlich vereinfacht wird. Im Weiteren ist mit einer solchen Unterteilung von Scharnierstift und radial ausladendem Bund bzw. konischer Ausrichtfläche der Vorteil verbunden, daß der Scharnierstift mit einem Kopfteil ausgestattet werden kann, welches die bisher erforderlichen, zusätzlich anzubringenden Sicherungsmittel gegen ein Wandern des Scharnierstiftes in axialer Richtung gegenüber demjenigen Scharnierauge, in welchem er mit Laufsitz und bleibend gelagert ist, entbehrlich macht.The separation of the actual hinge pin and the radially protruding one conical alignment surface bearing federal into two independent and each As an independent part, parts that can be assembled initially lead to the fact that the Hinge pin through the hinge eye of the hinge half in which he with Running seat is stored in the hinge and possibly in Also introduced in an attachment, such as a door lock can be done, thereby pre-assembling the hinge and attachment is significantly simplified. Furthermore, with such Subdivision of hinge pin and radially protruding collar or conical alignment surface the advantage that the hinge pin can be equipped with a headboard, which the previously required additional safety devices to prevent the hinge pin from moving in the axial direction compared to the hinge eye in which it is seated and stored permanently, makes it unnecessary.
In einer praktischen Verwirklichung eines aus zwei eigenständigen
Teilen zusammengesetzten Scharnierstiftes für aushängbare
Türscharniere ist vorgesehen, daß der Bund und die schräg zur
Scharnierachse gerichtete konische Ausrichtfläche des Scharnierstiftes
an einem mit einer zentralen Durchtrittsöffnung für den
Scharnierstiftschaft ausgestatteten, als Konusring ausgestalteten
Ringkörper ausgebildet sind.
Die erforderliche drehsichere Verbindung des Konusringes mit dem
Scharnierstift bzw. Scharnierstiftschaft kann in jeder bekannten
und geeigneten Weise hergestellt werden, wobei gemäß einer ersten
Gestaltungsform vorgesehen sein kann, daß der Konusring
vermittels einer axial gerichteten Innenumfangsprofilierung seiner
Durchtrittsöffnung und einer komplementären Außenumfangsprofilierung
des zugehörigen Längenabschnittes des Scharnierstiftschaftes
formschlüssig drehsicher mit dem Scharnierstift
verbindbar ist, was die Herstellung einer drehsicheres Verbindung
von Scharnierstift und Konusring durch einfaches Zusammenstecken
von Scharnierstift und Konusring im Zuge der Montage des
Scharnieres ermöglicht.
Gemäß einer zweiten Gestaltungsform kann aber auch vorgesehen
sein, daß der Konusring vermittels einer Innenumfangsprofilierung,
gegebenenfalls in Verbindung mit einer zumindest bereichsweisen
komplementären Außenumfangsgestaltung des Scharnierstiftschaftes,
kraftschlüssig drehsicher mit dem Scharnierstift verbindbar
ist. Bei dieser Gestaltungsweise einer drehsicheren Koppelung
von Scharnierstift und Konusring erfolgt die Herstellung
des Kraftschlusses zwischen Scharnierstiftschaft und Konusring
unter der Wirkung einer auf das freie Ende des Scharnierstiftschaftes
aufschraubbaren und die aushängbare Scharnierhälfte
gegen den Konusring verspannende, vorzugsweise als Konusmutter
ausgebildeten Mutter. Im Zusammenhang mit dieser Gestaltungsform
kann auch die Herbeiführung einer dauerhaft drehsicheren Verbindung
von Konusring und Scharnierstiftschaft im Wege der Ausnutzung
prägender Wirkungen bei Einsatz unterschiedlich harten Materials
einerseits für den Scharnierstift und andererseits für
den Konusring in Betracht gezogen werden.In a practical realization of a hinge pin composed of two separate parts for detachable door hinges, it is provided that the collar and the conical alignment surface of the hinge pin directed obliquely to the hinge axis are formed on an annular body designed as a conical ring and equipped with a central through opening for the hinge pin shaft.
The required rotationally secure connection of the cone ring with the hinge pin or hinge pin shaft can be produced in any known and suitable manner, it being possible according to a first design form that the cone ring by means of an axially directed inner circumferential profile of its passage opening and a complementary outer circumferential profile of the associated length section of the hinge pin shaft can be positively connected in a rotationally secure manner to the hinge pin, which enables the hinge pin and the cone ring to be connected in a rotationally secure manner by simply plugging the hinge pin and the cone ring together during the assembly of the hinge.
According to a second embodiment, it can also be provided that the conical ring can be non-positively connected to the hinge pin by means of an inner circumferential profiling, optionally in conjunction with an at least partially complementary outer circumferential configuration of the hinge pin shaft. With this design of a rotationally secure coupling of the hinge pin and the cone ring, the frictional connection between the hinge pin shaft and the cone ring takes place under the effect of a nut which is preferably designed as a cone nut and which can be screwed onto the free end of the hinge pin shaft and clamps the detachable hinge half against the cone ring. In connection with this design, the establishment of a permanently rotationally secure connection of the cone ring and hinge pin shaft by utilizing formative effects when using materials of different hardness can be considered on the one hand for the hinge pin and on the other hand for the cone ring.
In einer bevorzugten Einzelausgestaltung eines aushängbaren Türscharnieres mit zweiteilig ausgeführtem Scharnierstift ist weiterhin vorgesehen, daß der Schaftteil des Scharnierstiftes in axialer Richtung stufenförmig verkleinerten Durchmesser aufweist, derart, daß er mit zwei in axialer Richtung aufeinanderfolgenden Bunden versehen ist, wobei ein erster Bund im Anschluß an seine wartungsfreie Lagerung im Scharnierauge der einen Scharnierhälfte angeordnet ist und eine dem Konusring zugeornete axiale Abstützung bildet und ein zweiter Bund eine Durchmesserverringerung des Scharnierstiftschaftes den Bereich seines dem Aufsetzen einer Konusmutter zugeordneten Gewindeteiles begrenzt.In a preferred single configuration of a detachable Door hinge with a two-part hinge pin further provided that the shaft part of the hinge pin in has a smaller diameter in the axial direction, such that it has two successive axially Bundles is provided, with a first fret following of its maintenance-free storage in the hinge eye of some Hinge half is arranged and one of the cone ring assigned axial support forms and a second collar reduces the diameter the area of its hinge pin Attachment of a conical nut associated threaded part limited.
