The lower profile portion (14) which is introduced into the open underside of the double-walled, upper profile portion (12) bent from a metal sheet is produced from plastic, to be precise preferably an injection-moulded thermoplastic polymer. <IMAGE>

Description

Die Erfindung betrifft eine Schubladen-Seitenwand, bestehend aus einem aus Metallblech gekanteten doppelwandigen, an der Unterseite offenen oberen Profilabschnitt, in dessen offene Unterseite ein gesondert hergestellter und mit dem oberen Profilabschnitt verbundener unserer Profilabschnitt eingesetzt ist, so daß die Schubladen-Seitenwand ein geschlossenes Hohlprofil bildet.The invention relates to a drawer side wall, consisting of a double-walled, folded sheet metal, open at the bottom of the upper profile section, in the open bottom of which a separately manufactured and connected to the upper profile section of our profile section is inserted, so that the drawer side wall is a closed hollow profile forms.

Im Innenausbau und im Möbelbau werden in neuerer Zeit für bestimmte Einsatzfälle in zunehmendem Maße Schubladen verwendet, deren Schubladen-Seitenwände aus Kunststoff- oder Metallprofilen hergestellt sind, wobei Schubladen mit Seitenwänden aus metallischen Hohlprofilen inbesondere für große Schubladen mit hohem Fassungsvermögen verwendet werden, die zur Aufnahme schwerer Teile oder Gegenstände bestimmt, d.h. hohen Gewichtsbelastungen ausgesetzt sind. Als Metallprofile werden dabei überwiegend Hohlkammer-Profile aus Leichtmetallegierungen verwendet, welche neben der geforderten Belastbarkeit auch noch den Vorteil geringen Gewichts haben und - infolge ihrer Herstellung im Strang-Preßverfahren - auch mit solchen Querschnittsformen herstellbar sind, welche die Möglichkeit der verdeckten Anordnung von Verbindungsbeschlägen für die Verbindung der Seitenwände mit der Schubladen-Rückwand und/oder Frontblende, die Halterung des Schubladen-Bodens und die ebenfalls verdeckte Anordnung der Laufschiene der zugehörigen Ausziehführung bieten. Die aus Aluminium-Legierung stranggepreßten metallischen Hohlprofile sind aber infolge der erforderlichen hohen Investitionen für die Strangpreßanlagen und - formen vergleichsweise teuer.In interior design and in furniture construction, drawers are increasingly being used for certain applications, the drawer side walls of which are made of plastic or metal profiles, drawers with side walls made of hollow metal profiles being used in particular for large drawers with a large capacity for receiving heavy parts or objects determined, ie are exposed to high weight loads. Hollow-chamber profiles made of light metal alloys are predominantly used as metal profiles, which, in addition to the required load capacity, also have the advantage of low weight and - due to their production in the extrusion process - can also be produced with cross-sectional shapes that provide the possibility of concealed connection fittings for the connection of the side walls with the drawer rear wall and / or front panel, the holder of the drawer bottom and the concealed arrangement of the running rail of the associated pull-out guide. The hollow aluminum profiles extruded from aluminum alloy are comparatively expensive due to the high investments required for the extrusion systems and shapes.

Für die Herstellung von Metall-Schubladen-Seitenwänden in geringeren Stückzahlen und in Sondermaßen, für welche sich die Investitionen für Strangpreßanlagen nicht rechnen, ist andererseits bereits die Herstellung von metallischen Hohlkammer-Seitenwänden der eingangs erwähnten Art (DE-OS 39 34 419; Fig. 3) vorgeschlagen worden, bei welchem in den aus Metallblech gekanteten oberen Profilabschnitt ein ebenfalls aus Metallblech gekanteter unterer Profilabschnitt eingesetzt und die beiden Profilabschnitte dann durch elektrische Widerstandsschweißung miteinander verbunden werden. Dabei kann der untere Profilabschnitt auch so geformt sein, daß er gleichzeitig die Funktion der Laufschiene einer Rollen-Ausziehführung der Schublade übernimmt (DE-U- 9 102 828). Auf diese Weise hergestellte Hohlkammer-Seitenwandprofile aus Metallblech haben sich grundsätzlich für die erwähnten Sonderfälle bewährt, sind aber wegen des Erfordernisses der Verschweißung der Profilabschnitte immer noch relativ aufwendig und dementsprechend teuer in der Herstellung.For the production of metal drawer side walls in smaller quantities and in special sizes, for which the investments for extrusion systems are not worthwhile on the other hand, the production of metallic hollow chamber side walls of the type mentioned at the outset (DE-OS 39 34 419; FIG. 3) has been proposed, in which a lower profile section, likewise bent from sheet metal, is inserted in the upper profile section folded from sheet metal, and the two profile sections then can be connected to each other by electrical resistance welding. The lower profile section can also be shaped so that it simultaneously takes over the function of the running rail of a roller pull-out guide for the drawer (DE-U-9 102 828). Hollow-chamber side wall profiles made of sheet metal produced in this way have proven themselves in principle for the special cases mentioned, but are still relatively complex and accordingly expensive to manufacture because of the need to weld the profile sections.

Bei Hohlkammer-Seitenwandprofilen, bei denen der obere Profilabschnitt aus Kunststoff hergestellt ist, ist es bekannt, in die offene Unterseite dieses oberen Profilabschnitts einen unteren Profilabschnitt aus Kunststoff einzusetzen, der zur Einbettung und Befestigung der schubladenseitigen Laufschiene einer Ausziehführung dient (DE-A- 2 813 778). Die Art und Weise der Befestigung des unteren Kunststoff-Profilabschnitts im oberen Profilabschnitt bleibt dabei offen.In the case of hollow-chamber side wall profiles in which the upper profile section is made of plastic, it is known to use a lower profile section made of plastic in the open underside of this upper profile section, which is used for embedding and fastening the drawer-side slide rail of a pull-out guide (DE-A-2 813 778). The way of fastening the lower plastic profile section in the upper profile section remains open.

Der Erfindung liegt die Aufgabe zugrunde, ein ohne nachteilige Auswirkung hinsichtlich des Aussehens oder der Belastung für Schubladen-Seitenwände verwendbares Hohlkammer-Profil der eingangs erwähnten Art zu schaffen, welches auch in kleinen Serien noch einfacher und preisgünstiger als aus metallischen Profilabschnitten insgesamt hergestellte Hohlkammer-Profile produzierbar ist.The invention has for its object to provide a usable without drawback in terms of appearance or load for drawer side walls hollow chamber profile of the type mentioned, which even in small series even easier and cheaper than hollow chamber profiles made overall from metallic profile sections is producible.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der aus Metallblech gekantete obere Profilabschnitt mit Abstand von seinen, die offene Unterseite begrenzenden Rändern von den einander zugewandten Innenseiten der die Schubladen-Seitenwand bildenden senkrechten Wände je einen sich im wesentlichen über die gesamte Länge des Profilabschnitts erstreckenden Verbindungsflansch aufweist, welche jeweils von einem im wesentlichen rechtwinklig von der Innenseite der zugeordneten Wand vortretenden streifenförmigen Stegabschnitt und einem im wesentlichen rechtwinklig von der wandabgewandten Begrenzungskante des Stegabschnitts abgekanteten Schenkelabschnitt gebildet werden, daß im unteren aus Kunststoff hergestellten Profilabschnitt zwei jeweils einem der Verbindungsflansche zugeordnete, sich im wesentlichen über die gesamte Länge des Profilabschnitts erstreckende und wenigstens an einem Ende offen in einer Stirnfläche des unteren Profilabschnitts mündende Aufnahme-Nuten für jeweils einen der Verbindungsflansche vorgesehen sind, in welche die Verbindungsflansche formschlüssig eingreifen, und daß die Aufnahme-Nut von einer Anzahl von in Längsrichtung des unteren Profilabschnitts aufeinanderfolgenden und abwechselnd zur jeweils zugeordnten senkrechten Wand des oberen Profilabschnitts bzw. rechtwinklig hierzu zum Stegabschnitt des Verbindungsflanschs hin offenen Nut-Abschnitten gebildet wird. Die Verbindung des oberen metallischen Profilabschnitts mit dem unteren - zweckmäßig im Spritzgußverfahren hergestellten - Profilabschnitt erfolgt also durch Einschieben der Verbindungsflansche des oberen Profilabschnitts in die Aufnahme-Nut des unteren Profilabschnitts, wobei den Montageaufwand erhöhende gesonderte Arbeitsgänge zur Verbindung der beiden Profilabschnitte, wie Schweißen, Verschrauben, Vernieten o.dgl., entfallen können. Aufgrund der Unterteilung der Aufnahme-Nut in aufeinanderfolgende Nutabschnitte, die jeweils abwechselnd den Stegabschnitt bzw. den Schenkelabschnitt des Verbindungsflanschs unter- bzw. hintergreifen, sind diese Nut-Abschnitte jeweils zu einer Seite hin offen, wodurch die Herstellung dieses Profilabschnitts im Kunststoff-Spritzgußverfahren aus thermoplastischem Kunststoff ermöglicht wird, wobei die Spritzgußform trotz der - über die gesamte Länge gesehenen - winkelförmigen Ausgestaltung der Aufnahme-Nut relativ einfach ausgebildet werden kann, da zur Bildung der einzelnen Nut-Abschnitte jeweils einfache ebenflächig begrenzte Formenkerne vorgesehen werden können.According to the invention, this object is achieved in that the upper profile section folded from sheet metal is at a distance from its edges, which delimit the open underside, from the mutually facing inner sides of the vertical walls forming the drawer side wall, each has a connecting flange which extends essentially over the entire length of the profile section and which in each case projects from a wall which extends essentially at right angles from the inside of the associated wall Strip-shaped web section and a leg section bent substantially at right angles from the boundary edge of the web section facing away from the wall are formed so that in the lower profile section made of plastic, two each assigned to the connecting flanges, which extend essentially over the entire length of the profile section and are open at least at one end in one End face of the lower profile section opening receiving grooves are provided for each of the connecting flanges, in which the connecting flanges engage in a form-fitting manner, and that the receiving groove is formed by a number of groove sections which are successive in the longitudinal direction of the lower profile section and alternate to the respectively assigned vertical wall of the upper profile section or at right angles to the web section of the connecting flange. The connection of the upper metallic profile section with the lower - suitably manufactured by injection molding - profile section is thus carried out by inserting the connecting flanges of the upper profile section into the receiving groove of the lower profile section, the assembly work increasing separate operations for connecting the two profile sections, such as welding, screwing , Riveting or the like, can be omitted. Due to the subdivision of the receiving groove into successive groove sections, which alternately engage under or behind the web section or the leg section of the connecting flange, these groove sections are each open to one side, which means that this profile section is produced using the plastic injection molding process thermoplastic is made possible the injection mold, despite the angular configuration of the receiving groove, as seen over the entire length, can be made relatively simple, since simple, flat-surface mold cores can be provided to form the individual groove sections.

Die Verbindungsflansche sind dabei vorzugsweise als integrale Einheit der senkrechten Wände des oberen Profilabschnitts ausgebildet, wobei sie vom oberen Rand von Metall-Streifen abgekantet sein können, deren unterer Rand jeweils einstückig an jeweils einem der die offene Unterseite begrenzenden Ränder der senkrechten Profilabschnitt-Wände angesetzt und um 180° auf die Innenseite der jeweiligen Profilabschnitt-Wand umgekantet ist.The connecting flanges are preferably formed as an integral unit of the vertical walls of the upper profile section, whereby they can be bent from the upper edge of metal strips, the lower edge of which is attached in one piece to each of the edges of the vertical profile section walls delimiting the open underside and is folded over by 180 ° to the inside of the respective section wall.

Der untere Profilabschnitt aus Kunststoff hat in zweckmäßiger Weiterbildung der Erfindung im Querschnitt im wesentlichen die Form eines Winkelprofils mit zwei im Querschnitt im wesentlichen rechtwinklig zueinander verlaufenden Winkel-Schenkeln, von denen der horizontale Winkel-Schenkel im Innern des offenen Profilabschnitts angeordnet und dort mit diesem oberen Profilabschnitt verbunden ist, während der senkrechte Winkel-Schenkel aus der unteren Begrenzung des oberen Profilabschnitts vortritt.In an expedient further development of the invention, the lower profile section made of plastic has in cross section essentially the shape of an angle profile with two angle legs which are essentially perpendicular to one another in cross section, of which the horizontal angle leg is arranged inside the open profile section and there with this upper one Profile section is connected, while the vertical angle leg emerges from the lower boundary of the upper profile section.

An dem aus dem oberen Profilabschnitt nach unten vortretenden Winkel-Schenkel des unteren Profilabschnitts können dann Verbindungsmittel zur Halterung eines Schubladenbodens vorgesehen sein. Wenn dieser Schubladenboden von einer relativ dicken Platte aus Holzwerkstoff gebildet wird, können die Halterungsmittel von vom senkrechten Schenkel zum Schubladenboden vortretenden Harpunenstegen gebildet werden, die in entsprechende schlitzartige Ausnehmungen in den seitlichen Stirnflächen des Schubladenbodens eingeschlagen werden. Für dünnere Schubladenböden können die Halterungsmittel dann alternativ von einem vom unteren freien Rand des nach unten vorstehenden Winkel-Schenkels des unteren Profilabschnitts rechtwinklig zur Schubladen umgekanteten streifenförmigen Tragflansch gebildet werden, welcher den Schubladenboden untergreift.Connecting means for holding a drawer base can then be provided on the angle leg of the lower profile section which projects downward from the upper profile section. If this drawer base is formed by a relatively thick plate made of wood-based material, the holding means can be formed by speargun protrusions that protrude from the vertical leg to the drawer base and are hammered into corresponding slot-like recesses in the lateral end faces of the drawer base. For thinner drawer bottoms, the holding means can then alternatively be formed by a strip-shaped support flange bent from the lower free edge of the downwardly protruding angle leg of the lower profile section at right angles to the drawer, which engages under the drawer bottom.

Am rückwärtigen Ende des unteren Profilabschnitts aus Kunststoff werden zweckmäßig Mittel zur lösbaren Befestigung eines die Seitenwand mit der Schubladen-Rückwand verbindenden Eckverbinders vorgesehen, der beispielsweise ebenfalls aus Kunststoff hergestellt und mit dem unteren Profilabschnitt verschraubbar ist.At the rear end of the lower profile section made of plastic, means are expediently provided for releasably fastening a corner connector which connects the side wall to the drawer rear wall, for example is also made of plastic and can be screwed to the lower profile section.

Im vorderen frontblendenseitigen Endbereich des unteren Profilabschnitts sind dann zweckmäßig Mittel zur Halterung eines Frontblenden-Halterungsbeschlages vorgesehen, so daß dieser Frontblendenbeschlag also unsichtbar im Innern der Schubladen-Seitenwand liegt.Means are then expediently provided in the front front panel-side end region of the lower profile section for holding a front panel mounting fitting, so that this front panel fitting is therefore invisible in the interior of the drawer side wall.

Am unteren Profilabschnitt aus Kunststoff kann zumindest ein Teil der Befestigungseinrichtung für die lösbare Befestigung der Laufschiene einer Schubladen-Ausziehführung vorgesehen sein.At least a part of the fastening device for the releasable fastening of the running rail of a drawer pull-out guide can be provided on the lower profile section made of plastic.

Wenn die Befestigung der Laufschiene in an sich bekannter Weise im Bereich des korpusinneren rückwärtigen Ende mittels einer mit Abstand oberhalb und parallel zur Laufschiene vorgesehenen, in eine Bohrung in der korpusinneren Stirnfläche einschiebbaren Haltezunge oder eines Haltezapfens einerseits und eine zur Frontblende der Schublade versetzte, beim Einschieben der Laufschiene mit dieser in Rasteingriff kommenden und sie gegen Zurückziehen sichernden federnden Zunge andererseits erfolgt, kann die federnde Zunge von einem, entlang von drei Seiten aus dem nach unten vortretenden Winkel-Schenkel des unteren Profilabschnitts freigeschnittenen integralen Abschnitt des Winkel-Schenkels selbst gebildet werden.If the fastening of the running rail in a known manner in the area of the rear end of the body by means of a holding tongue or a holding pin, which is provided at a distance above and parallel to the running rail and can be inserted into a hole in the end face on the inside of the body, and a holding pin offset to the front panel of the drawer, when pushed in the running rail with this coming into engagement and securing it against pulling back resilient tongue on the other hand, the resilient tongue can be formed by an integral section of the angle leg itself, cut free on three sides from the downwardly protruding angle leg of the lower profile section.

In den Zeichnungsfiguren zeigt Figur 1 - in Explosionsdarstellung - eine in ihrer Gesamtheit mit 10 bezeichnete Schublade, von der allerdings - der besseren Übersichtlichkeit halber - die den Schubladenboden bildende Bodenplatte weggelassen ist. Die Schublade 10 setzt sich im übrigen aus den beiden, jeweils aus einem oberen aus Metallblech gekanteten doppelwandigen und einen Hohlraum einschließenden, an der Unterseite und den beiden Stirnseiten offenen Profilabschnitt 12 und einem im Bereich der offenen Unterseite in den Profilabschnitt 12 eingesetzten unteren Profilabschnitt 14 aus Kunststoff zusammengesetzten Schubladen-Seitenwänden 16, einer Frontblende 18 und einer über Eckverbinder 20 aus Kunststoff an den rückwärtigen Endflächen der Seitenwände gehaltenen Rückwand 22 zusammen, welche im dargestellten Fall einwandig aus Metallblech hergestellt ist. Für die Befestigung der Frontblende 18 an den Seitenwänden 16 sind lösbare Verbindungsbeschläge 24 vorgesehen, von denen jeweils ein Beschlagteil 24a an der Innenfläche der Frontblende 18 und der jeweils zugeordnete andere Beschlagteil 24b innerhalb des oberen Profilabschnitts 12 am unteren Profilabschnitt 14 befestigt ist. Die Art und Weise der Verbindung der Frontblende 18 mit den Seitenwänden 16 ist - ebenso wie die Verbindung der Rückwand 22 mit den Seitenwänden 16 über Eckverbinder - grundsätzlich bekannt und nicht Teil der Erfindung, welche sich mit der speziellen, nachstehend in Verbindung mit den Figuren 2 bis 5 näher erläuterten Ausgestaltung der Schubladen-Seitenwände 16 befaßt.In the drawing figures, FIG. 1 shows - in an exploded view - a drawer, designated in its entirety by 10, from which - for the sake of clarity - the base plate forming the drawer bottom is omitted. The drawer 10 is otherwise made up of the two, each consisting of an upper double-walled sheet metal and enclosing a cavity the underside and the two end faces open profile section 12 and a lower profile section 14 made of plastic composite drawer side walls 16 inserted in the area of the open bottom in the profile section 12, a front panel 18 and a corner connector 20 made of plastic on the rear end faces of the side walls 22 together, which is single-walled made of sheet metal in the case shown. Detachable connecting fittings 24 are provided for fastening the front panel 18 to the side walls 16, of which one fitting part 24a is fastened to the inner surface of the front panel 18 and the respective other fitting part 24b is fastened within the upper profile section 12 to the lower profile section 14. The manner in which the front panel 18 is connected to the side walls 16, like the connection of the rear wall 22 to the side walls 16 via corner connectors, is fundamentally known and is not part of the invention, which is related to the specific method described below in conjunction with FIGS. 2 to 5 design of the drawer side walls 16 discussed in more detail.

Der obere Profilabschnitt 12 ist - wie erwähnt - aus Metallblech gekantet und hat die in Figur 3 dargestellte Querschnittsform. D.h. er weist zwei an der Oberseite durch eine Stegfläche 28 auf Abstand gehaltene, im wesentlichen senkrechte Wände 30, 32 auf, die aus optischen Gründen und zur Versteifung noch in sich profiliert sein können. Am unteren Rand der äußeren Wand 30 ist einstückig ein Metallblechstreifen 35 angesetzt, der um 180° auf die Innenseite der Wand 30 umgekantet ist. Vom ursprünglich unteren und nunmehr innerhalb der Wände 30, 32 liegenden Rand ist ein nach innen weisender Verbindungsflansch 34 abgekantet, der sich aus einem rechtwinklig von der Innenfläche der Wand 30 vortretenden Stegabschnitt 36 und einem von dessen freiem, wandabgewandten Rand rechtwinklig nach unten umgekanteten Schenkelabschnitt 38 zusammensetzt. Ein dem Verbindungsflansch 34 entsprechender Verbindungsflansch 42 tritt von der Innenfläche der Wand 32 vor. Auch der Verbindungsflansch 42 ist von einem Metallstreifen 44 rechtwinklig abgekantet und setzt sich aus einem horizontalen Stegabschnitt 46 und einem senkrechten Schenkelabschnitt 48 zusammen.As mentioned, the upper profile section 12 is folded from sheet metal and has the cross-sectional shape shown in FIG. 3. This means that it has two essentially vertical walls 30, 32, which are spaced apart on the upper side by a web surface 28 and which can still be profiled in themselves for optical reasons and for reinforcement. At the lower edge of the outer wall 30, a metal sheet strip 35 is attached in one piece, which is folded over by 180 ° to the inside of the wall 30. An inwardly facing connecting flange 34 is folded from the originally lower and now inside the walls 30, 32, which flange consists of a web section 36 protruding at right angles from the inner surface of the wall 30 and a right-angled downward section from its free, wall-facing edge Leg section 38 is composed. A connecting flange 42 corresponding to the connecting flange 34 protrudes from the inner surface of the wall 32. The connecting flange 42 is also bent at right angles from a metal strip 44 and is composed of a horizontal web section 46 and a vertical leg section 48.

Zur Bildung einer Hohlkehle, welche einen ausgerundeten Übergang der inneren Wand 32 zum Schubladen-Boden bildet, ist die Wand 32 allerdings in ihrem unteren Randbereich 50 kreisbogenförmig nach außen gekrümmt, so daß zur Verbindung des Metallblechstreifens 44 mit dem unteren Rand der Wand 32 noch ein kurzer horizontaler streifenförmiger Abschnitt 52 vorgesehen sein muß.To form a fillet, which forms a rounded transition from the inner wall 32 to the drawer bottom, the wall 32 is curved in a circular arc outwards in its lower edge region 50, so that a connection to the metal sheet strip 44 with the lower edge of the wall 32 is still a short horizontal strip-shaped section 52 must be provided.

Der aus Kunststoff im Spritzgußverfahren hergestellte untere Profilabschnitt 14, und zwar dessen korpusinnerer Endbereich, ist in vergrößertem Maßstab in Figur 2 dargestellt, wobei erkennbar ist, daß die Verbindungsflansche 38, 46 des - in dieser Figur nur strichpunktiert dargestellten - oberen Profilabschnitts 12 in eine Aufnahmenut 54 eingreifen, die in der Oberseite eines im wesentlichen horizontal verlaufenden Winkel-Schenkels 56 des unteren Profilabschnitts 14 eingreifen, von dem im Bereich der inneren Wand 32 ein senkrechter Winkel-Schenkel 58 abgekantet ist, der noch aus der Unterseite des Profilabschnitts 12 vortritt.The lower profile section 14, which is made of plastic by injection molding, and specifically its end region inside the body, is shown on an enlarged scale in FIG. 2, whereby it can be seen that the connecting flanges 38, 46 of the upper profile section 12 - shown only in broken lines in this figure - into a receiving groove 54 engage, which engage in the top of an essentially horizontal angle leg 56 of the lower profile section 14, from which a vertical angle leg 58 is bent in the area of the inner wall 32, which still protrudes from the underside of the profile section 12.

In Figur 2 ist außerdem erkennbar, daß am rückwärtigen, d.h. korpusinneren Ende, des Profilabschnitts 14 ein in den zwischen den Wänden 30 und 32 gebildeten Hohlraum nach oben vortretender Vorsprung 16 vorgesehen ist, der in seiner ins Korpusinnere weisenden, bündig mit dem inneren Ende des oberen Profilabschnitts 12 liegenden Stirnfläche eine Gewindebohrung 62 aufweist. Eine weitere Gewindebohrung 62 ist in der rückwärtigen, den horizontalen Winkel-Schenkel 56 begrenzenden Endfläche vorgesehen. Diese Gewindebohrung dient zur Aufnahme von Befestigungsschrauben 64, mit denen die Eckverbinder 20 mit der jeweiligen Schubladen-Seitenwand 16 verschraubt werden.In Figure 2 it can also be seen that at the rear, ie inside the body, of the profile section 14, a protrusion 16 is provided which protrudes upwards into the cavity formed between the walls 30 and 32 and which is flush with the inside end of the inside of the body upper profile section 12 lying end face has a threaded bore 62. Another threaded hole 62 is in the rear, the horizontal angle leg 56 limiting end surface provided. This threaded hole serves to receive fastening screws 64 with which the corner connectors 20 are screwed to the respective drawer side wall 16.

Die Verbindungsflansche 34, 42 greifen in die jeweils zugeordnete Aufnahme-Nut 54 ein, d.h. diese Aufnahme-Nuten 54 haben - von der rückwärtigen Stirnfläche des unteren Profilabschnitts 14 aus gesehen - eine der Querschnittsform der Verbindungsflansche 34, 42 entsprechende Querschnittsform. Da eine durchgehende Aufnahme-Nut 54 mit dieser Querschnittsform aber - wenn überhaupt - nur schwer verwirklichbar ist, ist die Aufnahme-Nut in eine Anzahl von in Längsrichtung aufeinanderfolgende Nut-Abschnitte 66 bzw. 68 unterteilt, von denen beispielsweise der am rückwärtigen Ende vorgesehene, der äußeren Wand 30 zugeordnete letzte Nut-Abschnitt 66 die Breite des Stegabschnitts 38 hat und sich zur Wand 30 öffnet, während der nächstfolgende Nut-Abschnitt 68 nach oben, d.h. zur Stegfläche 28 des oberen Profilabschnitts 12 hin offen ist, so daß der Schenkelabschnitt 38 von oben in den Nut-Abschnitt 68 eingreift. Auf diese Weise wird der Verbindungsflansch 34 also abwechselnd in Nut-Abschnitten 66 und 68 gehalten, wodurch der untere Profilabschnitt 14 formschlüssig mit dem oberen Profilabschnitt 12 verbunden ist. Entsprechende Nut-Abschnitte 66, 68 sind dem Verbindungsflansch 42 zugeordnet, die zu den der Wand 30 zugeordneten Nut-Abschnitten 66, 68 zweckmäßig um jeweils die Länge eines Nut-Abschnitts versetzt angeordnet sind, so daß also einem dem Verbindungsflansch 34 an der Wand 30 zugeordneten Nut-Abschnitt 66 jeweils ein der Wand 32 zugeordneter Nut-Abschnitt 68 und den der Wand 30 zugeordneten Nut-Abschnitten 68 innenwandseitig jeweils ein Nut-Abschnitt 66 gegenüberliegt.The connecting flanges 34, 42 engage in the respectively assigned receiving groove 54, i.e. these receiving grooves 54 have - seen from the rear end face of the lower profile section 14 - a cross-sectional shape corresponding to the cross-sectional shape of the connecting flanges 34, 42. However, since a continuous receiving groove 54 with this cross-sectional shape is difficult to implement, if at all, the receiving groove is divided into a number of successively longitudinal groove sections 66 and 68, of which, for example, the one provided at the rear end, the last groove section 66 assigned to the outer wall 30 has the width of the web section 38 and opens to the wall 30, while the next groove section 68 upwards, ie is open towards the web surface 28 of the upper profile section 12, so that the leg section 38 engages in the groove section 68 from above. In this way, the connecting flange 34 is alternately held in groove sections 66 and 68, whereby the lower profile section 14 is positively connected to the upper profile section 12. Corresponding groove sections 66, 68 are assigned to the connecting flange 42, which are expediently offset by the length of a groove section from the groove sections 66, 68 assigned to the wall 30, so that one of the connecting flange 34 on the wall 30 assigned groove section 66 each has a groove section 68 assigned to wall 32 and a groove section 66 on the inside wall side of the groove sections 68 assigned to wall 30.

Die Unterteilung der Aufnahme-Nut 54 in die Nut-Abschnitte 66, 68 ermöglicht es, den unteren Profilabschnitt 14 aus Kunststoff zu spritzen, ohne daß die hierüber erforderliche Spritzgußform zu kompliziert wird. Die Montage des unteren Profilabschnitts 14 im oberen Profilabschnitt 12 erfolgt so, daß der Profilabschnitt 14 vom rückwärtigen oder vorderen offenen Ende her in den oberen Profilabschnitt 12 eingeschoben wird, wobei die Verbindungsflansche 34, 42 in der Aufnahme-Nut 54 verankert werden. Eine zusätzliche Fixierung des unteren Profilabschnitts 14 im oberen Profilabschnitt 12 ist nicht erforderlich, weil der untere Profilabschnitt 14 im oberen Profilabschnitt 12 am rückwärtigen Ende durch den Eckverbinder 20 und am vorderen, korpusäußeren Ende durch die Frontblende 18 gegen Verschiebung relativ zum oberen Profilabschnitt 12 gehalten ist.The subdivision of the receiving groove 54 into the groove sections 66, 68 makes it possible to inject the lower profile section 14 from plastic without the need for it Injection mold becomes too complicated. The lower profile section 14 is mounted in the upper profile section 12 in such a way that the profile section 14 is inserted into the upper profile section 12 from the rear or front open end, the connecting flanges 34, 42 being anchored in the receiving groove 54. An additional fixation of the lower profile section 14 in the upper profile section 12 is not necessary because the lower profile section 14 is held in the upper profile section 12 at the rear end by the corner connector 20 and at the front, outer end by the front panel 18 against displacement relative to the upper profile section 12 .

In Figur 1 sind am senkrechten Winkel-Schenkel 56 des unteren Profilabschnitts 14 voneinander beabstandete Harpunenstege 70 dargestellt, welche in einen Aufnahmeschlitz der entsprechend dick bemessenen Bodenplatte der Schublade eingeschlagen werden können und die Bodenplatte so fixieren.1 shows on the vertical angle leg 56 of the lower profile section 14 spaced-apart speargun webs 70 which can be driven into a receiving slot in the correspondingly thick base plate of the drawer and thus fix the base plate.

Alternativ kann am unteren Rand des Winkel-Schenkels 56 auch ein Tragflansch 72 (Fig. 4) vorgesehen sein, welcher dann die Bodenplatte 74 untergreift. Gegen ein Abheben vom Tragflansch 72 ist die Bodenplatte 74 durch den unteren gebogenen, die Hohlkehle bildenden Randabschnitt 50 der inneren Wand 32 gesichert.Alternatively, a support flange 72 (FIG. 4) can also be provided on the lower edge of the angle leg 56, which then engages under the base plate 74. The base plate 74 is secured against lifting off from the support flange 72 by the lower curved edge section 50 of the inner wall 32 forming the fillet.

In Figur 4 ist die Anordnung der die Schublade in einem Schrankkorpus ausziehbar führenden Laufschiene 76 einer Ausziehführung 78 dargestellt. Diese Laufschiene 76 kann an ihrem rückwärtigen Ende die übliche Haltezunge aufweisen, welche von einem aus dem Material der Laufschiene selbst freigestanzten und durch zweimalige Umkantung gebildeten Materialabschnitt gebildet wird. Diese Haltezunge wird zur Festlegung des korpusinneren Endes der Laufschiene 76 in eine zugeordnete Bohrung oder Aussparung im Eckverbinder 20 eingeschoben. Für die zusätzliche Festlegung der Laufschiene ist dann noch im senkrechten Winkel-Schenkel 58 des unteren Profilabschnitts 14 eine federnde Rastzunge 80 (Fig. 1) vorgesehen, welche mit einem (nicht gezeigten) Vorsprung bzw. einer Ausnehmung in der Laufschiene 76 zusammenwirkt und die vom rückwärtigen korpusinneren Ende aus in die Unterseite der Seitenwand 16 eingeschobene Laufschiene 76 gegen Zurückziehen verrastet. Diese federnde Zunge kann - bei hinreichender Elastizität des für die Herstellung des unteren Profilabschnitts 14 verwendeten Kunststoffs - ein integraler Teil des unteren Profilabschnitts 14 sein, so daß also die Befestigung einer gesonderten metallischen Zunge am Winkel-Schenkel 58 nicht erforderlich ist.FIG. 4 shows the arrangement of the slide rail 76 of a pull-out guide 78 that guides the drawer in a cabinet body. This running rail 76 can have the usual holding tongue at its rear end, which is formed by a material section stamped out of the material of the running rail itself and formed by two edging. This retaining tongue is inserted into an associated bore or recess in the corner connector 20 in order to fix the inner end of the running rail 76. For the additional fixing of the running rail 58 is then still in the vertical angle leg lower profile section 14, a resilient latching tongue 80 (FIG. 1) is provided, which cooperates with a projection (not shown) or a recess in the running rail 76 and which latches the running rail 76, which is pushed into the underside of the side wall 16 from the rear inside end, against retraction . This resilient tongue can - with sufficient elasticity of the plastic used for the production of the lower profile section 14 - be an integral part of the lower profile section 14, so that the attachment of a separate metallic tongue to the angle leg 58 is not necessary.
