In mehrfach aufeinanderfolgenden Stanz-Preß-Schritten aus metallischem Bandmaterial hergestellte Montageplatten setzen sich gegenüber den im Spritzgußverfahren aus Kunststoff und den im Druckgußverfahren aus Metallegierungen hergestellten Montageplatten in zunehmendem Maße durch, weil sie gegenüber den Kunststoff-Montageplatten erheblich höhere Festigkeit und gegenüber den Druckguß-Montageplatten deutlich geringeres Gewicht bei ebenfalls mindestens gleicher Festigkeit und dementsprechend geringere Herstellungskosten aufweisen. Außerdem ist es bei der Herstellung der Montageplatten aus federelastischem Blechmaterial möglich, durch geeignete konstruktive Ausgestaltung die federelastischen Eigenschaften für Rastmechanismen zu verwenden. Eine solche Anwendung ist beispielsweise aus der DE-OS 38 03 830 bekannt, welche eine zweiteilige Montageplatte offenbart, deren Oberteil aus Metallblech hergestellt ist, und die mit dem Unterteil über zwei integrale federnde Zungen verrastbar ist, dabei jedoch sehr einfach durch zusammendrücken der Zungen entrastet und dann - gegebenenfalls gemeinsam mit einem auf dem Oberteil gehaltenen Scharnier-Tragarm - vom Unterteil abgenommen werden kann. Die verstellbare Halterung des Tragarms eines zugehörigen Möbelscharniers auf der Montageplatte - bzw. einem oberen Montageplattenteil - erfolgt dabei einerseits durch die in die Gewindebohrung im korpusinneren Endbereich eingeschraubte und dabei den Tragarm klemmend und - durch Rastzähne od.dgl. - zusätzlich formschlüssig auf der Montageplatte festlegende Befestigungsschrauben und andererseits durch einen Gewindestift, dessen Gewindeschaft in einer Gewindebohrung im vorderen Endbereich des Tragarms eingeschraubt ist, während die Halterung auf der Montageplatte dadurch längsverschieblich ausgebildet ist, daß am montageplattenseitigen Ende des Gewindeschafts ein im Durchmesser verringerter gewindeloser Halsabschnitt angesetzt ist, der dann wieder in einen im Durchmesser vergrößerten Haltekopf übergeht. Der Halsabschnitt ist in einen vorn offen mündenden Längsschlitz passender Breite in der Stegfläche der Montageplatte eingeschoben und im Rahmen der Länge des Längsschlitzes somit verschieblich, jedoch gegen Abheben von der Montageplatte gesichert. Es ist klar, daß der Halsabschnitt nicht nur in seinem Durchmesser der Breite des Längsschlitzes, sondern auch in seiner Länge der Materialstärke des Stegabschnitts angepaßt sein muß, um unzulässiges Spiel zwischen dem Halsabschnitt - und somit dem Scharnier-Tragarm - und der Montageplatte im vorderen Tragarmbereich zu vermeiden. Gewindestifte mit Halsabschnitt und Haltekopf für die verstellbare Halterung des Scharnier-Tragarms werden von den Scharnierherstelltern auch für die Halterung der Tragarme auf Montageplatten aus Kunststoff und Metall-Druckguß verwendet. Dabei haben die Scharnier-Hersteller die unterschiedlichen Montageplatten und die Befestigungsmittel für die Tragarme, d.h. auch die Gewindestifte, so bemessen, daß die Tragarme von Scharnieren in gleicher Weise auf Montageplatten aus Kunststoff, Metall-Druckguß oder Blech montiert werden können. Das hat aber zur Folge, daß der Halsabschnitt des Gewindestifts in seiner Länge entsprechend der Wandstärke der den Längsschlitz seitlich begrenzenden Bereich von Kunststoff-Montageplatten abgestimmt sein muß. Da Kunststoff vergleichsweise geringere Festigkeit als Metallblech hat, sind im Schlitzbereich relativ große Wandstärken vorzusehen, d.h. der Halsabschnitt des Gewindestifts hat eine vorgegebene Länge, welche es bisher erforderlich machte, daß Blech-Montageplatten aus einem Blechmaterial mit einer Materialstärke hergestellt wurden, welche etwa der Länge des Halsabschnitts der Gewindestifte entsprach. Unter dem Gesichtspunkt der Festigkeit waren Montageplatten aus Metallblech solche Stärke dann in der Regel überdimensioniert. Die Herstellung aus dünnerem Metallblech verbot sich jedoch, da dann spezielle Gewindestifte mit verkürztem Halsabschnitt hätten verwendet werden müssen, was die wahlweise Montage der Scharnier-Tragarme auf Montageplatten aus unterschiedlichen Materialien unmöglich gemacht hätte.Mounting plates made from metallic strip material in multiple successive stamping-pressing steps are becoming increasingly prevalent over the plastic injection plates and the metal alloys using the die casting method, because they are considerably more rigid than the plastic mounting plates and compared to the die casting mounting plates have significantly lower weight with at least the same strength and accordingly lower manufacturing costs. In addition, when manufacturing the mounting plates from resilient sheet metal material, it is possible to use the resilient properties for locking mechanisms by means of a suitable structural design. Such an application is known for example from DE-OS 38 03 830, which discloses a two-part mounting plate, the upper part of which is made of sheet metal, and which can be latched to the lower part by means of two integral resilient tongues, but is unlocked very simply by pressing the tongues together and then - if necessary together with a hinge support arm held on the upper part - can be removed from the lower part. The adjustable mounting of the support arm of an associated furniture hinge on the mounting plate - or an upper mounting plate part - takes place on the one hand by screwing into the threaded hole in the interior end area and thereby clamping the support arm and - by locking teeth or the like. - In addition, form-fitting fixing screws on the mounting plate and, on the other hand, by means of a threaded pin, the threaded shaft of which is in a threaded hole in the front End portion of the support arm is screwed in, while the holder on the mounting plate is designed to be longitudinally displaceable in that a diameter-less threadless neck portion is attached to the mounting plate-side end of the threaded shaft, which then merges again into an enlarged holding head. The neck section is inserted into a longitudinal slot of suitable width opening in the front in the web surface of the mounting plate and is thus displaceable within the scope of the length of the longitudinal slot, but is secured against being lifted off the mounting plate. It is clear that the neck section must be adapted not only in its diameter to the width of the longitudinal slot, but also in its length to the material thickness of the web section in order to prevent undue play between the neck section - and thus the hinge bracket - and the mounting plate in the front bracket area to avoid. Hinge manufacturers also use setscrews with a neck section and holding head for the adjustable mounting of the hinge support arm for mounting the support arms on mounting plates made of plastic and die-cast metal. The hinge manufacturers have dimensioned the different mounting plates and the fastening means for the support arms, ie also the grub screws, so that the support arms of hinges can be mounted in the same way on mounting plates made of plastic, die-cast metal or sheet metal. However, this has the consequence that the length of the neck portion of the threaded pin must be matched to the wall thickness of the region of plastic mounting plates that laterally delimits the longitudinal slot. Since plastic has comparatively less strength than sheet metal, relatively large wall thicknesses are to be provided in the slot area, that is to say the neck portion of the threaded pin has a predetermined length, which previously made it necessary for sheet metal mounting plates to be produced from sheet metal material with a material thickness which was approximately the length corresponded to the neck section of the grub screws. In terms of strength, there were mounting plates Such thickness is usually oversized from sheet metal. However, the production from thinner sheet metal was prohibited because special set screws with a shortened neck section would then have had to be used, which would have made the optional mounting of the hinge support arms on mounting plates made of different materials impossible.

In der EP-A-0342293 ist in den Figuren 1 bis 3 ein Scharnier der eingangs erwähnten Art gezeigt, dessen aus Metallblech hergestellte Montageplatte in dem an den den Halsabschnitt des Gewindestifts aufnehmende Längsschlitz anschließenden Bereich aus der Ebene der Stegfläche heraus nach oben verformt ist. Der verformte Bereich ist jedoch ersichtlich breiter als der den Halsabschnitt unten abschließende Haltekopf bemessen. D.h. der Halsabschnitt des Gewindestifts kann - falls er im Längsschlitz in Richtung der Gewindestift-Längsachse kein merkliches Spiel haben soll - nur eine der Dicke des Metallblech-Ausgangsmaterials der Montageplatte im wesentlichen entsprechende Länge haben. Auf einer Montageplatte aus anderem dickerem Material, z.B. aus Zink-Druckguß, ist das Scharnier mit diesem Gewindestift also nicht montierbar.In EP-A-0342293, a hinge of the type mentioned at the outset is shown in FIGS. 1 to 3, the mounting plate made of sheet metal is deformed upwards out of the plane of the web surface in the region adjoining the longitudinal slot receiving the neck portion of the setscrew. However, the deformed area is obviously wider than the holding head that closes the neck section below. I.e. the neck portion of the grub screw can - if it should not have any noticeable play in the longitudinal slot in the direction of the grub screw longitudinal axis - only have a length which essentially corresponds to the thickness of the sheet metal starting material of the mounting plate. On a mounting plate made of other thicker material, e.g. made of die-cast zinc, the hinge cannot be mounted with this grub screw.

Aus der EP-A-0342293 ist auch ein Verfahren zur Herstellung eines derartigen Scharniers bekannt.A method for producing such a hinge is also known from EP-A-0342293.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, ein Scharnier mit einer im Stanz-Preßverfahren hergestellten Montageplatte bzw. einem Montageplattenteil und ein Verfahren zur Herstellung eines derartigen Scharniers zu schaffen, die bzw. der aus Blechmaterial mit verringerter Materialstärke hergestellt ist und trotzdem eine belastbare und spielfreie Halterung von Scharnier-Tragarmen ermöglicht, wobei der zu Halterung im Bereich des Längsschlitzes in der Stegfläche der Montageplatte dienende Gewindestift gegenüber den zur Halterung auf Montageplatten aus Kunststoff oder Metall-Druckguß verwendeten Gewindestift unverändert ist, d.h. eine Montage des Tragarms auf Montageplatten aus unterschiedlichen Materialien möglich ist.In contrast, the invention has for its object to provide a hinge with a mounting plate or a mounting plate part produced in the stamping and pressing method and a method for producing such a hinge, which or which is made of sheet material with reduced material thickness and yet a resilient and play-free Mounting of hinge support arms enables the set screw used for mounting in the area of the longitudinal slot in the web surface of the mounting plate to be unchanged compared to the set screw used for mounting on mounting plates made of plastic or die-cast metal, i.e. mounting the mounting arm on mounting plates made of different materials is possible is.

Ausgehend von einem Scharnier der eingangs erwähnten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß entlang der den Längsschlitz seitlich begrenzenden Ränder der Stegfläche der Montageplatte streifenförmige Bereiche um ein solches Maß aus der Ebene der Stegfläche herausgeformt sind, daß der von der den herausgeformten streifenförmigen Bereichen gegenüberliegenden Flachseite der unverformten Stegfläche zur gegenüberliegenden Begrenzungsfläche der herausgeformten streifenförmigen Bereiche parallel zur Gewindestiftachse gemessene Abstand größer als die Materialstärke der Stegfläche (52) im unverformten Bereich ist und gleich der Länge des Halsabschnitts des Gewindestifts ist, so daß der Halsabschnitt in Gewindestift-Längsrichtung im wesentlichen spielfrei im Längsschlitz der Montageplatte gehalten ist. Somit ist es möglich, im Bereich des Längsschlitzes der Montageplatte in Richtung der Längserstrekkung des Halsabschnitts des zugehörigen Gewindestifts eine hinreichende Materialstärke zur Verfügung zu stellen, obwohl die Materialstärke der Montageplatte deutlich geringer als die Länge des Halsabschnitts des Gewindestifts ist. Über die reine Funktion von Abstandsleisten, welche den Unterschied zwischen der Materialstärke der Montageplatte und der Länge des Halsabschnitts des Gewindestifts ausgleichen, haben die herausgeformten streifenförmigen Bereiche aber auch noch die Funktion von Versteifungsrippen, welche eine Verbiegung oder Verformung der seitlichen Schlitzränder entgegenwirken. Die erfindungsgemäße Montageplatte ist also aus deutlich dünneren Blechmaterialien herstellbar, was - nicht nur wegen des Preisvorteils des Ausgangsmaterials, sondern auch des geringeren Verschleißes der Stanz- und Preßwerkzeuge - zu einer wesentlichen Verbilligung der Herstellungskosten führt.Starting from a hinge of the type mentioned above, this object is achieved according to the invention in that strip-shaped regions are shaped out of the plane of the web surface along the edges of the web surface of the mounting plate that laterally delimit the longitudinal slot so that the opposite side of the molded strip-shaped regions The flat side of the undeformed web surface to the opposite boundary surface of the shaped strip-shaped regions parallel to the grub screw axis is greater than the material thickness of the web surface (52) in the undeformed region and is equal to the length of the neck section of the grub screw, so that the neck section in the grub screw longitudinal direction is essentially free of play is held in the longitudinal slot of the mounting plate. It is thus possible to provide a sufficient material thickness in the area of the longitudinal slot of the mounting plate in the direction of the longitudinal extent of the neck portion of the associated threaded pin, although the material thickness of the mounting plate is significantly less than the length of the neck portion of the threaded pin. Due to the pure function of spacer strips, which compensate for the difference between the material thickness of the mounting plate and the length of the neck section of the threaded pin, the shaped strip-shaped areas also have the function of stiffening ribs, which counteract bending or deformation of the lateral slot edges. The mounting plate according to the invention can thus be produced from significantly thinner sheet materials, which - not only because of the price advantage of the starting material, but also because of the lower wear of the punching and pressing tools - leads to a substantial reduction in manufacturing costs.

Ein weiterer Vorteil der Montageplatte wird sich daraus ergeben, daß auch Gewindestifte zur Anwendung kommen können, deren an der gewindeschaftabgewandten Stirnseite der Halsabschnitte angeordneten Halteköpfe unterschiedliche Form haben können. Während ursprünglich flache scheibenförmige Halteköpfe vorgesehen wurden, sind von der Anmelderin Gewindestifte mit kugelförmigem oder teilweise kugelförmigem Haltekopf entwickelt und verwendet worden, welche gegenüber den scheibenförmigen Halteköpfe deutliche Verbesserungen bezüglich der Verstellbarkeit des Tragarms auf der Montageplatte brachten. Für die Montage von Scharnier-Tragarmen mit solchen Gewindestiften mit kugel- bzw. kugelabschnittsförmigem Haltekopf empfiehlt sich eine Weiterbildung der Montageplatte derart, daß die beiden den Längsschlitz begrenzenden herausgeformten streifenförmige Bereiche die tragwandabgewandte obere Flachseite der Stegfläche der Montageplatte überragen, und daß der Übergang der den Längsschlitz begrenzenden Seitenflächen in die tragwandzugewandte Flachseite der Stegfläche die Form einer sich zur Stegfläche erweiternden Fase hat, wobei diese Fase unter einem mittleren Winkel von etwa 45° zur zugeordneten Stegfläche und zur jeweils zugeordneten Längsschlitz-Seitenfläche verlaufen. Der unmittelbar an den Halsabschnitt anschließende kugelige Bereich des Haltekopfs legt sich dann also an die von diesen Fasen gebildeten Flächen und nicht etwa eine durch den Stanzschnitt erzeugte scharfe Kante an. Die Fasen haben dabei zweckmäßig einen im Querschnitt bogenförmigen abgerundeten Verlauf.Another advantage of the mounting plate will result from the fact that grub screws can also be used, the holding heads of which on the end of the neck sections remote from the threaded shaft can have different shapes. While originally flat disc-shaped holding heads were provided, the applicant has set screws with spherical or partial ones spherical holding head have been developed and used, which compared to the disc-shaped holding heads brought significant improvements in the adjustability of the support arm on the mounting plate. For the assembly of hinge support arms with such grub screws with a spherical or spherical section-shaped holding head, a further development of the mounting plate is recommended such that the two shaped strip-shaped areas delimiting the longitudinal slot protrude beyond the upper flat side of the mounting plate facing away from the supporting wall, and that the transition of the Side surfaces delimiting the longitudinal slot in the flat side of the web surface facing the load-bearing wall has the shape of a chamfer widening to the web surface, this chamfer running at an average angle of approximately 45 ° to the associated web surface and to the respectively assigned longitudinal slot side surface. The spherical region of the holding head which immediately adjoins the neck section then bears against the surfaces formed by these chamfers and not, for example, a sharp edge produced by the stamped cut. The chamfers expediently have a rounded profile with an arcuate cross section.

Bei der Herstellung der Montageplatte für das erfindungsgemäße Scharnier wird neben den üblichen aufeinanderfolgenden Stanz- und Preßschritten so verfahren, daß vor dem Arbeitsschritt des Ausstanzens des Längsschlitzes aus dem aus dem Korpusinnern herausweisenden vorderen Endbereich der Stegfläche im Abstand der seitlich herausgeformten streifenförmigen Bereiche und über deren Länge ein mittig in Tragarm-Längsrichtung verlaufender, bandförmiger Stegflächenabschnitt hochgeprägt oder gezogen wird, dessen längsschlitzparallele Breite größer als die Breite des späteren Längsschlitzes in der fertigen Montageplatte ist, und daß dann aus dem bandförmigen Stegflächenabschnitt der Längsschlitz herausgestanzt wird.In the manufacture of the mounting plate for the hinge according to the invention, in addition to the The usual successive stamping and pressing steps are carried out in such a way that before the work step of punching out the longitudinal slot from the front end region of the web surface pointing out from the interior of the body, at a distance from the laterally shaped strip-shaped regions and over the length thereof, a band-shaped web surface section running centrally in the longitudinal direction of the support arm is embossed or is pulled, the longitudinal slot parallel width is greater than the width of the later longitudinal slot in the finished mounting plate, and that then the longitudinal slot is punched out of the band-shaped web surface portion.

Die die Seitenflächen des Längsschlitzes bildenden Stanzschnitte werden dabei derart durch den hochgeprägten oder gezogenen bandförmigen Stegflächenabschnitt gelegt, daß dieser bis auf die an den Längsschlitzrändern verbleibenden hochgekanteten Bereiche entfernt wird.The stamped cuts forming the side surfaces of the longitudinal slot are placed through the embossed or drawn band-shaped web surface section in such a way that it is removed except for the edged regions remaining on the longitudinal slot edges.

Der mit dem Längsschlitz zu versehende vordere Endbereich der Stegfläche der Montageplatte wird zweckmäßig vor dem Hochprägen oder -ziehen des langgestreckten bandförmigen Stegflächenabschnitts insgesamt um das Maß des Überstands der später verbleibenden hochgekanteten streifenförmigen Bereiche entgegengesetzt zu diesen in eine parallel zur restlichen Stegfläche verlaufende Ebene verformt. D.h. die freien Oberkanten der hochgekanteten streifenförmigen Bereiche liegen somit also in Flucht mit dem unverformten Teil der Stegfläche.The front end region of the web surface of the mounting plate, which is to be provided with the longitudinal slot, is expediently deformed before the embossing or pulling up of the elongated band-shaped web surface section by the amount of the protrusion of the later edged strip-shaped regions opposite to these into a plane running parallel to the remaining web surface. I.e. the free upper edges of the edged strip-shaped areas are thus in alignment with the undeformed part of the web surface.

In den Figuren 1 und 2 ist ein in seiner Gesamtheit mit 30 bezeichnetes erstes Ausführungsbeispiel einer in der erfindungsgemäßen Weise ausgestalteten Montageplatte gezeigt, auf welcher der als langgestreckter Tragarm ausgebildete Tragwand-Anschlagteil eines im übrigen dem Stand der Technik entsprechenden - und deshalb nicht dargestellten - Gelenkscharniers einstellbar befestigt ist. Hinsichtlich der Art und Weise der Ausgestaltung des auf der Montageplatte 30 zu befestigenden Scharnier-Tragarms möge es genügen, auf die Ausgestaltung des in den Figuren 1 und 2 der DE-OS 35 25 279 gezeigten und der zugehörigen Beschreibung beschriebenen Scharniers zu verweisen.1 and 2 show a first exemplary embodiment, designated in its entirety by 30, of a mounting plate designed in the manner according to the invention, on which the support wall stop part, which is designed as an elongated support arm, of an articulated hinge which is otherwise state-of-the-art and therefore not shown is adjustably attached. With regard to the manner of the design of the hinge support arm to be fastened on the mounting plate 30, it may suffice to refer to the design of the hinge shown in FIGS. 1 and 2 of DE-OS 35 25 279 and the associated description.

Die Montageplatte 30 weist einen langgestreckten leistenförmigen Halterungsabschnitt 32 auf, in dessen rückwärtigem, d.h. ins Korpusinnere weisenden Endbereich innerhalb eines mit Querriffelungen 34 versehenen Bereichs eine Gewindebohrung 36 vorgesehen ist, in welche der Schaft einer zur Befestigung des Scharnier-Tragarms dienenden Befestigungsschraube 38 einschraubbar ist. Im vorderen, d.h. aus dem Korpusinnern herausweisenden Endbereich weist der Halterungsabschnitt 32 eine in der vorderen Stirnfläche des Halterungsabschnitts 32 offen mündende und an der Oberseite für den Durchtritt des Halsabschnitts eines (nicht gezeigten) Gewindestifts zur Verstellung des Türflügel-Aufschlagmaßes schlitzförmig geöffnete Aussparungen 39 auf.The mounting plate 30 has an elongated strip-shaped mounting section 32, in the rear, i.e. A threaded bore 36 is provided in the end region pointing towards the inside of the body within a region provided with transverse corrugations 34, into which the shaft of a fastening screw 38 serving to fasten the hinge support arm can be screwed. In the front, i.e. from the end of the body pointing outward, the mounting section 32 has a recess 39 which opens openly in the front end face of the mounting section 32 and is open at the top for the passage of the neck section of a setscrew (not shown) for adjusting the door wing opening dimension.

Die Montageplatte 30 ist im dargestellten Fall zweiteilig ausgeführt und setzt sich aus einem direkt auf der Korpus-Tragwand zu befestigenden unteren Montageplattenteil 40, der nicht aus Metallblech, sondern aus Metall-Druckguß hergestellt ist, und einem auf dem unteren Montageplattenteil 40 verrasteten, im Rahmen der vorliegenden Erfindung interessierenden oberen Montageplattenteil 42 (Fig. 2, 3 und 4) aus Metallblech zusammen. Beim dargestellten Ausführungsbeispiel ist die Montageplatte 30 als sogenannte Flügelplatte ausgebildet, bei denen von dem zur einstellbaren Befestigung eines zugehörigen Scharnier-Tragarms dienenden leistenförmigen mittleren Halterungsabschnitt 32 an gegenüberliegenden Seiten je ein Flügelansatz 44 vortritt, die üblicherweise zur Befestigung der Montageplatte auf der Tragwand dienen. Der im wesentlichen den oberen Halterungsabschnitt 32 bildenden obere Montageplattenteil 42 ist auf dem unteren Montageplattenteil 40 aufgesetzt und in der nachfolgend noch beschriebenen Weise mit ihm verrastet. Die Flügelansätze 44 sind die äußeren Endabschnitte einer - beispielsweise wiederum im Stanz-Preßverfahren aus Metallblech - gesondert hergestellten, in einer passenden Ausnehmung in der Unterseite des unteren Montageplattenteils 40 liegenden und mit diesem verschraubten einstückigen Flügelplatte. Zur Befestigung der Montageplatte 30 auf einer Korpus-Tragwand werden (nicht gezeigte) Befestigungsschrauben durch angesenkte Öffnungen 46 in den Flügelansätzen 44 (Fig. 1) in Bohrungen im Korpus-Tragwandteil geschraubt. Die von den Flügelansätzen 44 gebildete Flügelplatte und der untere Montageplattenteil 42 ihrerseits sind durch eine Befestigungsschraube 48 (Fig. 1 und 2) miteinander verbunden, deren Schaft durch ein quer zur Montageplatten-Längsrichtung verlaufendes Langloch 50 in eine (nicht gezeigte) Gewindebohrung in der Flügelplatte eingeschraubt ist. Bei gelockerter Befestigungsschraube 48 ist also eine gewisse, durch die Länge des Langlochs 50 vorgegebene Verschiebung des unteren Montageplattenteils 44 relativ zur Flügelplatte, d.h. eine Höheneinstellung eines auf der Montageplatte 30 gehalterten Scharniers möglich.The mounting plate 30 is made in two parts in the case shown and is composed of a lower mounting plate part 40 which is to be fastened directly to the body supporting wall, which is not made of sheet metal, but made of die-cast metal, and a latched on the lower mounting plate part 40, in the frame upper mounting plate part 42 (Figs. 2, 3 and 4) of the present invention made of sheet metal. In the illustrated embodiment, the mounting plate 30 is designed as a so-called wing plate, in which a strip attachment 44, which usually serves for fastening the mounting plate on the supporting wall, emerges from the strip-shaped central mounting section 32 serving for the adjustable fastening of an associated hinge support arm. The upper mounting plate part 42, which essentially forms the upper mounting section 32, is placed on the lower mounting plate part 40 and locked with it in the manner described below. The wing lugs 44 are the outer end sections of a - for example again in the stamping-pressing process made of sheet metal - separately manufactured, lying in a suitable recess in the underside of the lower mounting plate part 40 and screwed to this one-piece wing plate. To fasten the mounting plate 30 to a body support wall, fastening screws (not shown) are screwed through countersunk openings 46 in the wing extensions 44 (FIG. 1) into bores in the body support wall part. The wing plate formed by the wing lugs 44 and the lower mounting plate part 42 are in turn connected to one another by a fastening screw 48 (FIGS. 1 and 2), the shaft of which through an elongated hole 50 running transversely to the mounting plate longitudinal direction into a threaded hole (not shown) in the wing plate is screwed in. When the fastening screw 48 is loosened, a certain displacement of the lower mounting plate part 44, predetermined by the length of the elongated hole 50, relative to the wing plate, ie a height adjustment of a hinge held on the mounting plate 30, is possible.

Der in den Figuren 3 und 4 gesondert dargestellte obere Montageplattenteil 42 weist einen umgekehrt U-förmigen Querschnitt auf, d.h. er setzt sich aus einer oberen langgestreckten Stegfläche 52 und an deren gegenüberliegenden Längsrändern angesetzten, den unteren Montageplattenteil 40 seitlich teilweise umgreifenden Wangen 54 zusammen, wobei in der Stegfläche 52 der offen mündende Längsschlitz 39 und eine durchgehende Öffnung 56 vorgesehen ist, welche das Lösen bzw. Anziehen der Befestigungsschraube 48 ermöglicht. Im rückwärtigen, d.h. ins Korpusinnere weisenden Endbereich ist die Stegfläche 52 in Abwärtsrichtung zu einer Stirnwand 58 umgekantet, in welcher eine querverlaufende, fensterartige Öffnung 60 (oder zwei in seitlichem Abstand benachbarte fensterartige Öffnungen 60) vorgesehen sind.The upper mounting plate part 42 shown separately in Figures 3 and 4 has an inverted U-shaped cross section, i.e. It is composed of an upper elongated web surface 52 and cheeks 54 which are partially attached to the lower longitudinal plate part 40 and are attached to the opposite longitudinal edges thereof. The open surface longitudinal slot 39 and a continuous opening 56 are provided in the web surface 52, which enable the release or Tightening the fastening screw 48 allows. In the back, i.e. In the end region pointing towards the inside of the body, the web surface 52 is folded downward to form an end wall 58, in which a transverse window-like opening 60 (or two window-like openings 60 adjacent to one another at a lateral distance) are provided.

Durch einen vom korpusinneren Ende her parallel zur Stegfläche 52 in die Wangen 54 eingearbeiteten Trennschnitt oder Schlitz 62 sind in den rückwärtigen Bereichen der Wangen langgestreckte streifenförmige Abschnitte freigeschnitten, welche die im folgenden noch näher erläuterten federnden Zungen 64 bilden, die ihrerseits Teil eines Rastmechanismus sind, welche die lösbare Verrastung des rückwärtigen Endes des oberen und des unteren Montageplattenteils 42 bzw. 40 ermöglicht.Elongated strip-shaped sections are cut out in the rear regions of the cheeks by a separating cut or slot 62 machined into the cheeks 54 from the inside of the body parallel to the web surface 52, which form the resilient tongues 64, which are explained in more detail below, which in turn are part of a locking mechanism, which enables the releasable locking of the rear end of the upper and lower mounting plate parts 42 and 40, respectively.

Die die Zungen bildenden freigeschnittenen streifenförmigen Abschnitte 64 sind also an ihrem Vorderende einstückig mit den Wangen 54 verbunden.Die Zungen verbiegen sich bei seitlich aufgebrachtem Druck vorzugsweise im Bereich der Zungen-Teilabschnitte 66 federnd elastisch. Im Anschluß an den federnden Teilabschnitt 66 ist jeweils ein Zungenabschnitt 68 schräg nach außen und ins Korpusinnere weisend gebogen, an welchen sich jeweils ein in eine etwa parallel zur Längsmittelachse verlaufende Lage zurückgebogener, eine Handhabe bildender Zungenabschnitt 70 anschließt, von dem wiederum jeweils ein Zungenabschnitt 72 nach innen zur Längsmittelachse umgekantet ist, von welchem schließlich jeweils ein letzter, den eigentlichen Rastabschnitt 74 der jeweiligen federnden Zunge 64 bildender Zungenabschnitt zurückgekantet ist, und zwar so, daß diese Zungen- oder Rastabschnitte 74 durch die fensterartige(n) Öffnung(en) 60 in der rückwärtigen Stirnwand 58 hindurch ins Innere des oberen Montageplattenteils 42 eintreten.The cut-out strip-shaped sections 64 which form the tongues are thus connected in one piece to the cheeks 54 at their front end. When the pressure is applied laterally, the tongues preferably bend elastically in the region of the tongue subsections 66. Following the resilient subsection 66, a tongue section 68 is bent obliquely outwards and into the interior of the body, to each of which a tongue section 70, bent back into a position approximately parallel to the longitudinal central axis, connects, of which in turn each a tongue section 72 is folded back inwards to the longitudinal central axis, of which a last tongue section, which forms the actual latching section 74 of the respective resilient tongue 64, is folded back, in such a way that these tongue or latching sections 74 pass through the window-like opening (s) 60 enter the rear mounting wall 58 into the interior of the upper mounting plate part 42.

Im vorderen Endbereich ist in jeder Wange 54 des oberen Montageplattenteils 42 je eine schräg nach rückwärts geöffnete Hakenaufnahme 76 mit einer abschnittsweise kreisbogenförmigen Eingriffsfläche ausgebildet.In the front end region, in each cheek 54 of the upper mounting plate part 42, a hook receptacle 76, which is opened obliquely towards the rear, is formed with an engagement surface that is circular in sections.

Den Hakenaufnahmen 76 sind am unteren Montageplattenteil 40 seitlich vortretende Hakenvorsprünge 78 mit ebenfalls zumindest abschnittsweise komplementär kreisbogenförmig ausgebildeten Eingriffsflächen zugeordnet, so daß es möglich ist, die Hakenaufnahmen 76 des oberen Montageplattenteils 52 mit hochgeschwenktem rückwärtigem Ende in der in Fig. 2 veranschaulichten Weise über die Hakenvorsprünge 78 zu führen und dann nach Anlage der Eingriffsflächen aneinander das rückwärtige Ende des oberen Montageplattenteils 42 in Abwärtsrichtung auf den unteren Montageplattenteil 40 herabzuschwenken. Dabei treten dann die ins Innere des Montageplattenteils 52 zurückgekanteten Rastabschnitte 74 der Zungen 64 in eine am rückwärtigen Ende des unteren Montageplattenteils 40 vorgesehene, an der Oberseite und der rückwärtigen Stirnkante offen mündende Aussparung 80 ein, welche an der Oberseite durch einwärts aufeinanderzu gerichtete Vorsprünge 82 verengt ist. An der Unterseite bilden die leistenartigen Vorsprünge 82 daher Hinterschnittflächen 84, während die gegenüberliegenden oberen Flächen als sich von oben nach unten schräg verjüngende Anlauf-Schrägflächen 86 ausgebildet sind. Beim Herabschwenken des rückwärtigen Endes des Montageplattenteils 42 auf den Montageplattenteil 40 treffen die inneren Enden der Rastabschnitte 74 auf die Anlauf-Schrägflächen 86 und gleiten dann - unter federnder Verformung der Zungen 64 insgesamt - auf den Schrägflächen 86 herab, bis ihre oberen Ränder bei Erreichen der bestimmungsgemäßen Raststellung über die zwischen den leistenartigen Vorsprüngen 82 gebildete Engstelle hinwegtreten und hinter die den Hinterschnittflächen 84 auffedern, wobei dann die obere Kante der Rastabschnitte 74 an der zugeordneten Hinterschnittfläche 84 verriegelt, während ihre untere Kante an der unteren horizontalen Kante der fensterartigen Öffnung 60 als Gegenlager abgestützt ist. Dann ist ein Zurückschwenken des oberen Montageplattenteils 42 nicht mehr möglich, es sei denn, daß zuvor die Rastabschnitt 74 durch Ausübung eines Drucks auf die die Handhaben bildenden Zungenabschnitte 70 so weit nach innen gedrängt werden, daß sie von den Hinterschnittflächen 84 freikommen. Dabei ist wesentlich, daß beiden Rastabschnitte 74 von der jeweils zugeordneten Hinterschnittfläche 84 freikommen, was also ersichtlich die Ausübung von entgegengesetzt gerichteten Entriegelungskräften auf die beiden Zungenabschnitte erfordert. In der Praxis erfolgt dies zweckmäßig so, daß die Entriegelungskräfte durch Ausübung von entgegengesetzt gerichtetem Druck auf die Außenseiten der Zungenabschnitte 70 mittels des Daumens und des Zeigefingers der entriegelten Person erfolgt. Sobald der obere Montageplattenteil vom unteren Montageplattenteil entriegelt ist, d.h. die Rastabschnitte 74 von den Hinterschnittflächen 84 freikommen, kann dann das rückwärtige Ende des oberen Montageplattenteils 42 mit den Druck ausübenden Fingern nach oben gezogen und so der obere Montageplattenteil 42 hochgeschwenkt werden. Sofern dabei auf dem oberen Montageplattenteil 42 der Tragarm eines Scharniers befestigt ist, wird dieser dann natürlich mitverschwenkt, was ja möglich ist, da er seinerseits über seinen Gelenkmechanismus mit dem Türflügel-Anschlagteil verschwenkbar verbunden ist. Insoweit entspricht die beschriebene Montageplatte 30 der aus der DE-OS 38 03 830 bekannten Montageplatte, bei welcher die Materialstärke des zur Herstellung des oberen Montageplattenteils verwendeten Metallblechs etwa entsprechend der Länge des Halsabschnitts eines im Tragarm eines Möbelscharniers eingeschraubten zur Halterung und Verstellung auf der Montageplatte dienenden Gewindestifts gewählt ist.The hook receptacles 76 on the lower mounting plate part 40 are associated with laterally protruding hook projections 78 with engagement surfaces which are also formed at least partially complementarily in a circular arc, so that it is possible to hook the hook receptacles 76 of the upper mounting plate part 52 with the rear end pivoted up in the manner illustrated in FIG. 2 78 to guide and then after the engagement surfaces against each other, the rear end of the upper mounting plate part 42 in the downward direction down to the lower mounting plate part 40. The locking sections 74 of the tongues 64, which are folded back into the interior of the mounting plate part 52, then enter a recess 80 provided at the rear end of the lower mounting plate part 40 and open at the top and the rear end edge, which narrows at the top by projections 82 directed towards one another is. On the underside, the strip-like projections 82 therefore form undercut surfaces 84, while the opposite upper surfaces are designed as tapered bevel surfaces 86 which taper from top to bottom. When the rear end of the mounting plate part 42 is pivoted down onto the mounting plate part 40 meet the inner ends of the latching sections 74 on the run-up inclined surfaces 86 and then slide - with resilient deformation of the tongues 64 as a whole - down on the inclined surfaces 86 until their upper edges pass over the narrow point formed between the strip-like projections 82 when the intended latching position is reached and spring open behind the undercut surfaces 84, the upper edge of the latching sections 74 then locking on the associated undercut surface 84, while its lower edge is supported on the lower horizontal edge of the window-like opening 60 as a counter bearing. Then a swiveling back of the upper mounting plate part 42 is no longer possible, unless the latching section 74 is pushed so far inward by exerting pressure on the tongue sections 70 forming the handles that they come free from the undercut surfaces 84. It is essential that the two latching sections 74 are released from the respectively assigned undercut surface 84, which obviously means that opposing unlocking forces have to be exerted on the two tongue sections. In practice, this is expediently carried out such that the unlocking forces are exerted by exerting oppositely directed pressure on the outer sides of the tongue sections 70 by means of the thumb and the index finger of the unlocked person. As soon as the upper mounting plate part is unlocked from the lower mounting plate part, ie the latching sections 74 are released from the undercut surfaces 84, the rear end of the upper mounting plate part 42 can then be pulled upwards with the fingers exerting pressure and the upper mounting plate part 42 can thus be pivoted up. If the support arm of a hinge is fastened to the upper mounting plate part 42, this is then of course also pivoted, which is possible since it is in turn pivotally connected to the door leaf stop part via its hinge mechanism. In this respect, the mounting plate 30 described corresponds to the mounting plate known from DE-OS 38 03 830, in which the material thickness of the metal sheet used to produce the upper mounting plate part approximately corresponds to the length of the neck portion of a screwed into the support arm of a furniture hinge for mounting and adjustment on the mounting plate Grub screw is selected.

Demgegenüber sei die Materialstärke des oberen Montageplattenteils 42 (oder - bei einer einstückigen Montageplatte - der Gesamtmontageplatte) geringer. Wenn bei der bekannten Montageplatte eine Blechstärke von 1,5 mm verwendet wurde, soll der Montageplattenteil 42 nunmehr beispielsweise aus 1 mm starkem Blech hergestellt werden. Es entsteht dann das früher geschilderte Problem, daß die Länge des in den Längsschlitz 39 einzuführenden Halsabschnitts 90 des Gewindestifts 92 eines zugehörigen Scharnier-Tragarms 94 (Fig. 7) entsprechend der ursprünglichen Materialstärke von 1,5 mm der bekannten Montageplatte bemessen ist, d.h. daß bei Herstellung des Längsschlitzes 39 im erfindungsgemäßen Montageplattenteil 42 durch einfaches Ausstanzen von Material aus der Stegfläche 52 der Zwischenraum zwischen der unteren halsabschnittsseitigen Stirnfläche des Gewindeschafts 96 und dem auf der gegenüberliegenden Seite des Halsabschnitts 90 angesetzten scheibenförmigen Haltekopf 98 (Fig. 7) bzw. kugelförmigen Haltekopf des Gewindestifts 92 größer als die Bereiche der den Längsschlitz 39 begrenzenden Schlitzränder oder -Seitenflächen wären und der Tragarm 94 also in Richtung der Längsmittelachse des Gewindestifts 92 mit merklichem Spiel (etwa 0,5 mm) auf der Montageplatte gehalten wäre. Ein solches Spiel wurde den Tragarm 94 auch dann, wenn er durch die Befestigungsschraube 38 fest auf den Montageplattenteil 42 aufgepreßt ist, labil machen und ist deshalb nicht hinnehmbar.In contrast, the material thickness of the upper mounting plate part 42 (or - in the case of a one-piece mounting plate - the overall mounting plate) is less. If a sheet thickness of 1.5 in the known mounting plate mm was used, the mounting plate part 42 is now to be produced, for example, from 1 mm thick sheet metal. There then arises the problem described earlier that the length of the neck portion 90 of the threaded pin 92 of an associated hinge support arm 94 (FIG. 7) to be inserted into the longitudinal slot 39 is dimensioned in accordance with the original material thickness of 1.5 mm of the known mounting plate, ie that When the longitudinal slot 39 is produced in the mounting plate part 42 according to the invention by simply punching out material from the web surface 52, the space between the lower end face side of the threaded shaft 96 and the disk-shaped holding head 98 (FIG. 7) or spherical holding head attached to the opposite side of the neck section 90 of the threaded pin 92 would be larger than the areas of the slot edges or side surfaces delimiting the longitudinal slot 39 and the support arm 94 would thus be held on the mounting plate with noticeable play (approximately 0.5 mm) in the direction of the longitudinal central axis of the threaded pin 92. Such play would make the support arm 94 unstable even when it is pressed firmly onto the mounting plate part 42 by the fastening screw 38 and is therefore unacceptable.

Um dieses Spiel auszugleichen sind entlang der seitlichen Längsränder des Längsschlitzes 39 der Montageplatte 42 streifenförmige Bereiche 100 aus der Ebene der Stegfläche 52 heraus verformt, deren Überstand über die Stegfläche gerade dem Unterschied zwischen der Länge des Halsabschnitts 90 und der Materialstärke der (unverformten) Stegfläche 52 entspricht. Auf der den hochgeformten streifenförmigen Bereichen 100 gegenüberliegenden Unterseite sind die Übergänge zwischen den streifenförmigen Bereichen 100 und der unteren Flachseite der Stegfläche 52 jeweils als Fase 102 ausgebildet, die jeweils gegensinnig unter einem mittleren Winkel von etwa 45° zur Stegfläche und zur jeweils zugeordneten Längsschlitz-Seitenfläche verlaufen.In order to compensate for this play, strip-shaped regions 100 are deformed out of the plane of the web surface 52 along the lateral longitudinal edges of the longitudinal slot 39 of the mounting plate 42, the projection thereof over the web surface being precisely the difference between the length of the neck portion 90 and the material thickness of the (undeformed) web surface 52 corresponds. On the underside opposite the raised strip-shaped areas 100, the transitions between the strip-shaped areas 100 and the lower flat side of the web surface 52 are each formed as chamfer 102, each in opposite directions at an average angle of approximately 45 ° to the web surface and to the associated longitudinal slot side surface run.

Die Fasen 102 können entweder ebenflächig sein oder einen im Querschnitt bogenförmigen Verlauf haben. An diesen Fasen 102 legt sich im Falle der Verwendung eines Gewindestifts 92 mit kugelförmigem oder zumindest teilweise kugelförmigem Haltekopf dieser Haltekopf an, während bei Verwendung des in Fig. 7 gezeigten Gewindestifts 92 mit scheibenförmigem Haltekopf 98 dessen dem Gewindeschaft 96 zugewandten Flachseite an der unteren Flachseite der Stegfläche 52 anliegt.The chamfers 102 can either be flat or have an arcuate cross section. If a set screw 92 with a spherical or at least partially spherical holding head is used, this holding head bears against these chamfers 102, while when using the set screw 92 shown in FIG Retaining head 98, the flat side of which faces the threaded shaft 96 abuts the lower flat side of the web surface 52.

Bei der Herstellung des Montageplattenteils 42 (oder einer einstückigen Montageplatte) wird in grundsätzlich bekannter weise aus metallischem Bandmaterial in aufeinanderfolgenden Stanz- und Preßschritten, d.h. in Folgestationen, der Montageplattenteil hergestellt, wobei vor dem Arbeitsschritt des Ausstanzens des Längsschlitzes 39 im Bereich der späteren Längsränder des Längsschlitzes die in Fig. 8 gezeigten langgestreckten Wülste 104 in die Stegfläche 52 eingeprägt werden, deren Höhe bezogen auf die obere Flachseite der Stegfläche 52 dem gewünschten Überstand der den Längsschlitz 39 später, d.h. nach dessen Einstanzen in die Stegfläche, überragenden streifenförmigen Bereiche 100 entspricht. Der seitliche Abstand der Wülste 104 ist dabei so gewählt, daß beim anschließenden Stanz-Arbeitsschritt die die seitlichen Ränder des Längsschlitzes 39 bildenden Stanzschnitte 106 durch den Scheitelbereich der Wülste 104 verlaufen. Bei dem als Ausführungsbeispiel beschriebenen und in den Zeichnungsfiguren gezeigten Montageplattenteil 42 sind die Wülste 104 von der Stegfläche 52 aus nach oben hochgeprägt, so daß sie von der Flachseite vortreten und dementsprechend ist der den Längsschlitz aufnehmende vordere Bereich 52a der Stegfläche 52 um das Maß des Überstandes der streifenförmigen Bereiche 100 über die Oberfläche dieses Stegflächen-Bereichs 52a in eine parallel zum rückwärtigen Teil der Stegfläche 52 verlaufende Ebene nach unten verformt, wodurch die oberen freien Stirnkanten der streifenförmigen Bereiche 100 bündig mit der oberen Flachseite des rückwärtigen Bereichs der Stegfläche 52 verlaufen.In the production of the mounting plate part 42 (or a one-piece mounting plate), metal strip material is produced in a known manner in successive stamping and pressing steps, i.e. in subsequent stations, the mounting plate part is produced, the elongated beads 104 shown in FIG. 8 being embossed into the web surface 52, the height of which relative to the upper flat side of the web surface 52, being embossed in the region of the later longitudinal edges of the longitudinal slot before the working step of punching out the longitudinal slot 39 desired projection of the longitudinal slot 39 later, ie after punching it into the web surface, corresponds to protruding strip-shaped regions 100. The lateral spacing of the beads 104 is selected such that during the subsequent stamping step, the punch cuts 106 forming the lateral edges of the longitudinal slot 39 run through the apex area of the beads 104. In the case of the mounting plate part 42 described as an exemplary embodiment and shown in the drawing figures, the beads 104 are embossed upwards from the web surface 52 so that they protrude from the flat side and accordingly the front region 52a of the web surface 52 receiving the longitudinal slot is by the amount of the projection of the strip-shaped regions 100 is deformed downward over the surface of this web surface region 52a into a plane running parallel to the rear part of the web surface 52, as a result of which the upper free end edges of the strip-shaped regions 100 are flush with the upper flat side of the rear region of the web surface 52.

Anstelle einer Verformung der Wülste 104 nach oben ist grundsätzlich auch eine entgegengesetzte Verformung möglich, wobei dann das parallele Verformen des vorderen Bereichs 52a der Stegfläche 52 entfallen kann. Allerdings kann sich bei dieser Ausgestaltung der Haltekopf 98 eines Gewindestifts 92 nur an den Stirnkanten der streifenförmigen Bereiche abstützen.Instead of a deformation of the beads 104 upwards, an opposite deformation is in principle also possible, in which case the parallel deformation of the front region 52a of the web surface 52 can then be omitted. In this embodiment, however, the holding head 98 of a threaded pin 92 can only be supported on the end edges of the strip-shaped regions.
