Abstract

The part of the side walls (12) facing the adjacent side end edge (32) of the drawer bottom (14) has at least one anchoring protuberance (34) piercing the material forming the drawer bottom. The protuberance protrudes beyond the strips (24) protruding beyond the drawer's side walls, at right angles to the direction in which the drawer slides out or in a staggered position to them. A harpoon shaped protuberance fits into a groove (30) in the end edge of the drawer bottom. Crosswise to the harpoon arm sections (28a) is a ridge-shaped protuberance (34) the free edge of which is sharply pointed.

Description

Die Erfindung betrifft eine Befestigungsanordnung für den Boden einer Schublade an deren Seitenwänden, bei welcher integral von den Seitenwänden vorstehende, in Schubladen-Ausziehrichtung verlaufende leistenartige Vorsprünge die Ober- und/oder Unterseite des Bodens übergreifen und von einem dem Boden zugewandten Bereich der Seitenwände jeweils wenigstens ein bei der Montage der Schublade ins Material des Bodens eindringender Verankerungsvorsprung vorgesehen ist, welcher die leistenartigen Vorsprünge rechtwinklig zur Schubladen-Ausziehrichtung überragt oder zu ihnen versetzt ist.The invention relates to a fastening arrangement for the bottom of a drawer on its side walls, in which strip-like projections projecting integrally from the side walls and extending in the drawer pulling direction overlap the top and / or bottom of the bottom and at least one area of the side walls facing the bottom an anchoring projection penetrating into the material of the floor is provided during assembly of the drawer, which protrudes beyond the strip-like projections at right angles to the drawer pulling direction or is offset from them.

Bei der Herstellung von Schubladen werden im heutigen Möbelbau neben den klassischen Holzwerkstoffen zunehmend auch Profile aus Metall oder Kunststoff für Schubladen-Seitenwände verwendet. Metall-Seitenwandprofile können beispielsweise im Strang-Preßverfahren aus Aluminium oder aus Metallblech ausgestanzt und gekantet werden. Kunststoff-Seitenwandprofile werden in der Regel extrudiert und auf die gewünschte Länge geschnitten oder auch im Kunststoffspritzgußverfahren hergestellt. Bei solchen Seitenwandprofilen wird der in der Regel weiterhin aus Holz hergestellte Boden auf einem integral von Seitenwandprofil vorstehenden leistenartigen Vorsprung aufgesetzt oder in den Zwischenraum zwischen zwei in Höhenrichtung um das Maß der Dicke des Bodens versetzte leistenartige Vorsprünge eingesetzt (EP-A-0 281 766). Zur zusätzlichen Verbindung des Bodens mit den Seitenwänden wird an den Seitenwänden oft auch ein sogenannter Harpunensteg, d.h. eine auf beiden Flachseiten mit im Querschnitt sägezahnförmigen parallelen Verankerungsrippen versehene Befestigungsleiste vorgesehen, welche in eine gegenüber der über die Spitzen der sägezahnförmigen Rippen gemessenen Rippendicke in ihrer Breite mit Untermaß bemessene Längsnut in der seitenwandzugewandten Stirnkante des Schubladen-Bodens eingepreßt wird (EP-A-0 441 162). Diese sägezahnförmigen Verankerungsrippen graben sich nach dem Verpressen des Seitenwandprofils mit dem Boden in die Seitenwände der Längsnut ein und setzen dann dem Herausziehen des Harpunenstegs aus der Längsnut entgegen der Einpreßrichtung einen hohen Widerstand entgegen. Es hat sich nun gezeigt, daß in Einzelfällen unter bestimmten ungünstigen Umständen die Befestigung des Bodens an den Seitenwänden kritisch werden kann, und zwar wurde beobachtet, daß es bei häufig geöffneten und mit Schwung wieder geschlossenen und mit hohem Gewicht belasteten Schubladen infolge der beim Auftreffen der Schubladen-Frontblende auf den Schrank-korpus entstehenden Stoßbeanspruchungen zu einem Wandern des Schubladen-Bodens in Schubladen-Schließrichtung kommen kann, und zwar auch bei der Verbindung der Seitenwand mit dem Boden durch die erwähnten Harpunenstege. Durch zusätzliche Maßnahmen, z.B. das Eindrehen von Schrauben durch Bohrungen in einem der leistenförmigen Vorsprünge in den Schubladen-Boden läßt sich ein solches Wandern zwar verhindern, wobei jedoch zusätzlicher Montageaufwand entsteht, der in der modernen Großserienfertigung unerwünscht ist. Ein Wandern des Schubladen-Bodens relativ zu den Seitenwänden wird verhindert, wenn von den den Schubladen-Boden untergreifenden leistenartigen Vorsprüngen zum Schubladen-Boden vortretende Verankerungsvorsprünge vorgesehen werden, welche bei der Montage der Schublade ins Material des Schubladen-Bodens eingraben und so eine formschlüssige Festlegung des Schubladen-Bodens relativ zu seinen Seitenwänden sicherstellen (EP-A-0 322 545; EP-A-0 444 014). Die Montage des Schubladen-Bodens an den Schubladen-Seitenwänden erfolgt dann so, daß der Boden auf die leistenförmigen Vorsprünge aufgedrückt wird. Eine Montage durch seitliches Aufpressen der Schubladen-Seitenwände über die Stirnseite des Schubladen-Bodens ist dann nicht möglich.In the manufacture of drawers in today's furniture construction, profiles made of metal or plastic are increasingly being used for drawer side walls in addition to the classic wood-based materials. Metal sidewall profiles can be punched out and folded, for example, in the extrusion process from aluminum or from sheet metal. Plastic sidewall profiles are usually extruded and cut to the desired length or also manufactured using the plastic injection molding process. With such side wall profiles, the floor, which is generally still made of wood, is placed on a strip-like projection which projects integrally from the side wall profile or is inserted into the space between two strip-like projections which are offset in the vertical direction by the thickness of the floor (EP-A-0 281 766) . For the additional connection of the floor to the side walls, a so-called harpoon bridge is often provided on the side walls, ie a fastening strip provided on both flat sides with a sawtooth-shaped parallel anchoring ribs in cross section, which is pressed into a longitudinal groove, dimensioned with an undersize, in the width facing the tips of the sawtooth-shaped ribs in the front edge of the drawer bottom facing the side wall (EP-A-0 441 162). These sawtooth-shaped anchoring ribs dig into the side walls of the longitudinal groove after the side wall profile has been pressed in and then offer a high resistance to the pulling out of the speargun bridge from the longitudinal groove against the pressing direction. It has now been shown that, in individual cases, under certain unfavorable circumstances, the attachment of the floor to the side walls can become critical, and it has been observed that it is when the drawer is opened that it is opened frequently and closed again with momentum and it is loaded with heavy weight Drawer front panel on the cabinet body resulting shock loads can cause the drawer bottom to move in the drawer closing direction, even when the side wall is connected to the floor through the mentioned speargun bars. Such measures can be prevented by additional measures, for example the screwing in of screws through bores in one of the strip-shaped projections in the drawer bottom, but additional assembly effort is incurred which is undesirable in modern large-scale production. A migration of the drawer bottom relative to the side walls is prevented if anchoring protrusions are provided which protrude from the strip-like projections under the drawer bottom to the drawer bottom and dig into the material of the drawer bottom during assembly of the drawer and thus form-fitting fixing ensure the drawer bottom relative to its side walls (EP-A-0 322 545; EP-A-0 444 014). The drawer bottom is then mounted on the drawer side walls in such a way that the bottom is pressed onto the strip-shaped projections. It is then not possible to mount the side walls of the drawer over the front of the drawer bottom.

Der Erfindung liegt die Aufgabe zugrunde, eine Befestigungsanordnung für die Verbindung des Bodens einer Schublade an deren Seitenwände anzugeben, welche ohne das Erfordernis zusätzlicher, montageaufwendiger Maßnahmen ein Wandern des Schubladen-Bodens relativ zu den Seitenwänden auch bei hoher Belastung der Schublade und stoßartigen Beanspruchungen mit Sicherheit ausschließt.The invention has for its object to provide a mounting arrangement for connecting the bottom of a drawer on the side walls, which without the need for additional, assembly-intensive measures to move the drawer bottom relative to the side walls even with high load on the drawer and shock loads excludes.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein als Harpunensteg ausgebildeter leistenförmiger Vorsprung in eine in der Stirnkante des Schubladen-Bodens eingearbeitete Nut eingreift, daß der Harpunensteg durch wenigstens eine Unterbrechung in eine Anzahl von in Längsrichtung aufeinander folgende Harpunensteg-Abschnitte unterteilt ist, und daß im Bereich der Unterbrechung(en) ein quer zu den Harpunensteg-Abschnitten verlaufender rippenartiger Vorsprung oder ein zu den Harpunensteg-Abschnitten fluchtender Steg mit über das Maß der größten Dicke des Harpunenstegs vorstehenden, bei der Montage ins Material der Nut-Seitenwände eindringenden zahnartigen Verankerungsansätzen als Verankerungsvorsprung von der Seitenwand vortritt bzw. vortreten. Die Montage der Schubladen-Seitenwände am Schubladen-Boden ist damit in der gewünschten Weise durch Aufpressen auf die seitlichen Stirnkanten des Schubladen-Bodens möglich, wobei der als Verankerungsvorsprung dienende rippenartige Vorsprung bzw. die Verankerungsansätze des Stegs ein Wandern des Schubladen-Bodens relativ zu den Seitenwänden mit Sicherheit verhindern.This object is achieved in that a strip-shaped projection designed as a speargun bridge engages in a groove worked into the front edge of the drawer bottom, that the speargun bridge is divided by at least one interruption into a number of consecutive speargun bridge sections in the longitudinal direction, and in that in the area of the interruption (s), a rib-like projection running transversely to the speargun bridge sections or a bridge aligned with the speargun bridge sections with tooth-like anchoring approaches protruding beyond the dimension of the greatest thickness of the speargun bridge and penetrating into the material of the groove side walls during assembly Anchoring projection protrudes from the side wall. The assembly of the drawer side walls on the drawer bottom is thus possible in the desired manner by pressing onto the lateral front edges of the drawer bottom, the rib-like projection serving as an anchoring projection or the anchoring approaches of the web causing the drawer bottom to move relative to the Safely prevent side walls.

Bei Ausbildung des Verankerungsvorsprungs als querverlaufender rippenartiger Vorsprung ist dann die seitenwandabgewandte freie Kante des Vorsprungs zweckmäßig schneidenartig zugeschärft, um das Eindringen in das Material des Bodens beim Montagevorgang zu erleichtern und eine Beschädigung des Bodens zu vermeiden.When the anchoring projection is designed as a transverse rib-like projection, the free edge of the projection facing away from the side wall is then advantageously sharpened in a cutting-like manner in order to penetrate the material of the floor during the assembly process and to avoid damaging the floor.

Wenn der Verankerungsvorsprung bzw. die Verankerungsvorsprünge von jeweils einem zu den Harpunensteg-Abschnitten fluchtenden Steg mit über das Maß der größten Dicke des Harpunenstegs vorstehenden, bei der Montage ins Material der Nut-Seitenwände eindringenden zahnartigen Verankerungssätzen gebildet werden, ist es von Vorteil, wenn die zahnartigen Verankerungsansätze rechtwinklig zur Schubladen-Ausziehrichtung und zu den Seitenwand-Flachseiten verlaufende zugeschärfte Messerkanten aufweisen, welche ein Eindringen der Verankerungsansätze in die Nut der Seitenwände erleichtern.If the anchoring projection or the anchoring projections are each formed by a web aligned with the speargun bridge sections with tooth-like anchoring sets projecting beyond the dimension of the greatest thickness of the speargun bridge and penetrating into the material of the groove side walls during assembly, it is advantageous if the have tooth-like anchoring approaches at right angles to the drawer pulling direction and to the side wall flat sides of sharpened knife edges which facilitate penetration of the anchoring approaches into the groove of the side walls.

Diese zahnartigen Verankerungsansätze weisen dann zweckmäßig rechtwinklig zur Schubladen-Ausziehrichtung und zu den Seitenwand-Flachseiten verlaufende zugeschärfte Messerkanten auf, welche ein Eindringen der Verankerungsansätze in die Nut der Seitenwände erleichtern.These tooth-like anchoring approaches then expediently have sharpened knife edges which run at right angles to the drawer pulling direction and to the side wall flat sides, which facilitate penetration of the anchoring approaches into the groove of the side walls.

Von Vorteil ist es, wenn der Verankerungsvorsprung bzw. die Verankerungsvorsprünge jeweils integrale Teil der zugeordneten Schubladen-Seitenwand ist bzw. sind.It is advantageous if the anchoring projection or the anchoring projections is or are in each case an integral part of the associated drawer side wall.

Fig. 1 zeigt schematisch eine in ihrer Gesamtheit mit 10 bezeichnete, in dieser Form bekannte Schublade, welche sich aus zwei im speziellen Fall im Strangpreßverfahren aus einer Aluminiumlegierung hergestellten Seitenwandprofilen 12, einem in der Zeichnung nur gestrichelt angedeuteten hölzernen Boden 14, einer hölzernen Rückwand 16 und einer strichpunktiert angedeuteten Frontblende 18 zusammensetzt. Die Art und Weise der Verbindung der Rückwand 16 und der Frontblende 18 mit den Seitenwandprofilen 12 ist - weil nicht Gegenstand der Erfindung - nicht dargestellt. Hierfür können übliche bekannte Verbindungsbeschläge Verwendung finden.1 schematically shows a drawer, designated in its entirety by 10, which is known in this form and which consists of two side wall profiles 12 produced in an extrusion process from an aluminum alloy, a wooden floor 14 indicated only in dashed lines, and a wooden rear wall 16 and a front panel 18 indicated by dash-dotted lines. The manner in which the rear wall 16 and the front panel 18 are connected to the side wall profiles 12 is not shown, because it is not the subject of the invention. Commonly known connection fittings can be used for this.

Die - in dieser Form bekannten - Seitenwandprofile 12 weisen einen senkrechten, das Schubladeninnere seitlich begrenzenden Stegabschnitt 20 auf, an dessen oberem Rand ein rechtwinklig nach außen umgekanteter schmalerer streifenförmiger Schenkelabschnitt 22 einstückig angesetzt ist. Im Bereich des unteren Rands springen insgesamt drei leistenförmige Vorsprünge in Höhenrichtung versetzt parallel zueinander etwa rechtwinklig in Richtung zum Schubladen-Boden 14 vor. Der untere leistenförmige Vorsprung 24 untergreift und der obere leistenförmige Vorsprung 26 übergreift den Boden 14, d.h. der lichte Abstand zwischen den leistenförmigen Vorsprüngen 24, 26 entspricht etwa der Dicke des Bodens 14. Die in der fertig montierten Schublade 10 sichtbare Oberseite des oberen leistenförmigen Vorsprungs 26 ist dabei im Querschnitt nach Art einer Hohlkehle ausgerundet, wodurch die Reinigung der Schublade im Übergangsbereich zwischen dem Boden 14 und dem Seitenwandprofil 12 erleichtert wird. Der etwa mittig zwischen den leistenförmigen Vorsprüngen 24, 26 verlaufende Vorsprung ist als durchgehender Harpunensteg 28 ausgebildet, der in eine in ihrer Breite mit Untermaß bemessene Längsnut 30 (Fig. 3 und 6) in der zugewandten Stirnkante 32 des Bodens 14 einschlag- oder einpreßbar ist.The - in this form known - side wall profiles 12 have a vertical web section 20 which laterally delimits the inside of the drawer, on the upper edge of which a narrow strip-shaped leg section 22 bent outwards at right angles is attached in one piece. In the area of the lower edge, a total of three strip-shaped projections project in the vertical direction offset parallel to one another approximately at right angles in the direction of the drawer bottom 14. The lower strip-shaped projection 24 engages underneath and the upper strip-shaped projection 26 overlaps the base 14, ie the clear distance between the strip-shaped projections 24, 26 corresponds approximately to the thickness of the base 14. The upper side of the upper strip-shaped projection 26 visible in the fully assembled drawer 10 is rounded in cross-section in the manner of a groove, which makes cleaning the drawer in the transition region between the base 14 and the side wall profile 12 easier. The projection running approximately in the middle between the strip-shaped projections 24, 26 is designed as a continuous speargun web 28 which can be knocked in or pressed into a longitudinal groove 30 (FIGS. 3 and 6) which is undersized in width in the facing end edge 32 of the base 14 .

Bei dem in Fig. 2 bis 4 dargestellten Ausführungsbeispiel ist das Seitenwandprofil 12 gegenüber dem in Fig. 4 dargestellten bekannten Seitenwandprofil insofern abgewandelt, als der Harpunensteg in regelmäßigen Abständen unterbrochen ist, so daß er also von einer Anzahl von kürzeren, in Schubladen-Ausziehrichtung beabstandeten Harpunensteg-Abschnitten 28a gebildet wird.In the embodiment shown in FIGS. 2 to 4, the side wall profile 12 is modified compared to the known side wall profile shown in FIG. 4 in that the speargun bridge is interrupted at regular intervals, so that it is spaced from a number of shorter ones in the drawer pulling direction Harpoon bridge sections 28a is formed.

Im Bereich der Unterbrechnungen springen quer zu den Harpunensteg-Abschnitten verlaufende rippenartige Vorsprünge 34 vom Stegabschnitt 2o der Seitenwandprofile 12 vor, die an ihrer seitenwandabgewandten freien Kante 36 schneidenartig zugeschärft sind.In the area of the interruptions, rib-like projections 34 projecting transversely to the harpoon bridge sections protrude from the bridge section 20 of the side wall profiles 12, which are sharpened like a blade on their free edge 36 facing away from the side wall.

Es ist ersichtlich, daß diese querverlaufenden rippenförmigen Vorsprünge, welche die seitlichen Begrenzungen der Harpunensteg-Abschnitte 28a in Querrichtung überragen, beim Zusammenpressen der Seitenwandprofile 12 und des Bodens 14 in die Stirnkanten des Bodens 14 einschneiden und so eine sichere Fixierung des Bodens gegen Verschiebungen relativ zu den Seitenwandprofilen 12 in Schubladen-Auszieh- bzw. Einschubrichtung bewirken.It can be seen that these transverse rib-like projections, which project beyond the lateral boundaries of the speargear web sections 28a in the transverse direction, cut into the end edges of the base 14 when the side wall profiles 12 and the base 14 are pressed together, and thus secure the base against displacement relative to cause the side wall profiles 12 in the drawer pull-out or insertion direction.

Das in den Fig.5 bis 7 dargestellte Seitenwandprofil 12 unterscheidet sich von dem vorstehend erläuterten, in den Fig. 1 bis 3 gezeigten Seitenwandprofil lediglich hinsichtlich der Ausbildung der Verankerungsvorsprünge. An die Stelle der quer zu den Harpunensteg-Abschnitten 28a verlaufenden rippenartigen Vorsprünge 34 treten hier zu den Harpunensteg-Abschnitten 28a fluchtend ausgerichtete Stege 38 vorgesehen sind, welche im Querschnitt sägezahnförmige seitlich über das Maß der größten Dicke der Harpunensteg-Abschnitte 28a vortretende, rechtwinklig zur Schubladen-Ausziehrichtung verlaufende Verankerungsansätze 40 aufweisen. Diese Verankerungsansätze sind also mit in die Seitenwände der Nut 30 des Bodens 14 eindringenden messerartigen Schneiden versehen und stellen somit wieder die Fixierung des Bodens 14 gegen eine Verschiebung in Schubladen-Einschubrichtung relativ zu den Seitenwandprofilen 12 sicher. Durch Anordnung der beschriebenen Verankerungsansätze in im Wechsel um 180° verdrehter Lage kann auch eine Fixierung des Bodens zusätzlich in Ausziehrichtung verwirklicht werden.The side wall profile 12 shown in FIGS. 5 to 7 differs from the above-explained side wall profile shown in FIGS. 1 to 3 only with regard to the design of the anchoring projections. Instead of the rib-like projections 34 which run transversely to the speargear web sections 28a, there are webs 38 which are aligned in alignment with the harpoon web sections 28a and which, in cross section, are sawtooth-shaped and occur at right angles to the dimension of the greatest thickness of the speargun web sections 28a Have drawer pulling direction extending anchoring lugs 40. These anchoring approaches are thus provided with knife-like blades penetrating into the side walls of the groove 30 of the base 14 and thus again provide the fixation of the base 14 against displacement in the drawer insertion direction relative to the side wall profiles 12. By arranging the anchoring approaches described in an alternately rotated position by 180 °, the floor can also be additionally fixed in the pull-out direction.

Es ist ersichtlich, daß im Rahmen des Erfindungsgedankens Abwandlungen und Weiterbildungen der speziell beschriebenen Ausführungsbeispiele verwirklichbar sind. So kann die Sicherung der Seitenwand gegen Verschiebung relativ zum Boden in analoger Weise auch bei aus Kunststoff extrudierten oder spritzgegossenen Seitenwänden erfolgen. Auch die speziell beschriebene Form der Ankervorsprünge kann abgewandelt werden. Wesentlich ist lediglich, daß sie nach dem Eindringen in die Stirnwand des Schubladen-Bodens zusätzlich zu den Harpunenstegen in der Nut im Schubladen-Boden eine formschlüssige Verankerung der Seitenwand mit dem Boden bewirken. Dabei kann es durchaus auch zweckmäßig sein, wenn die Verankerungsvorsprünge zunächst gesondert hergestellt und dann im vorgesehenen Verankerungsbereich an der Seitenwand befestigt werden.It can be seen that modifications and developments of the specifically described exemplary embodiments can be implemented within the scope of the inventive concept. The side wall can thus be secured against displacement relative to the floor in an analogous manner even in the case of side walls extruded or injection molded from plastic. The specially described shape of the anchor projections can also be modified. It is only essential that, after penetrating the front wall of the drawer bottom, in addition to the speargun webs in the groove in the drawer bottom, they bring about a positive anchoring of the side wall to the floor. It can also be useful if the anchoring protrusions are first manufactured separately and then attached to the side wall in the intended anchoring area.
