Description

Die vorliegende Erfindung bezieht sich auf eine Schubladenausziehführung mit wenigstens einer Führungsschiene, wobei die Führungsschiene einen längserstreckten ersten Steg und zumindest einen vom ersten Steg abgewinkelten, längserstreckten zweiten Steg aufweist, wobei der erste Steg und der zweite Steg entlang ihrer Längsrichtung durch einen Abwinklungsbereich miteinander verbunden sind.The present invention relates to a drawer pull-out guide with at least one guide rail, the guide rail having an elongate first web and at least one elongate second web angled from the first web, the first web and the second web being connected to one another along their longitudinal direction by an angled area .

Im Weiteren betrifft die Erfindung eine Schubladenausziehführung mit wenigstens einer Führungsschiene der zu beschreibenden Art sowie ein Verfahren zur Herstellung einer Führungsschiene für eine Schubladenausziehführung.Furthermore, the invention relates to a drawer slide with at least one guide rail of the type to be described and a method for producing a guide rail for a drawer slide.

Derartige Führungsschienen werden für Schubladenausziehführungen eingesetzt, sodass eine Schublade in Montagelage relativ zu einem Möbelkorpus herausziehbar gelagert ist. Die Schubladenausziehführungen weisen üblicherweise eine an einem Möbelkorpus zu befestigende erste Führungsschiene und zumindest eine zweite Führungsschiene auf, welche relativ zu ersten Führungsschiene verschiebbar gelagert ist. Zur Realisierung eines Vollauszuges der Schublade relativ zum Möbelkorpus kann noch eine verschiebbar gelagerte dritte Führungsschiene angeordnet werden. Zur Lagerung der verschiebbaren Führungsschienen sind Wälzkörper vorgesehen, welche in einem Laufwagen oder auch in mehreren verschiebbaren Laufwagen gelagert sind. Durch speziell geformte Führungsschienen kann die Stabilität und die Belastungskapazität der Schubladenausziehführung verbessert werden. Bei Verwendung von großen Materialstärken bilden die Führungsschienen einen runden Abwinklungsbereich aus, wodurch auch ein erhöhter Bauraum vorzusehen ist. Eine gattungsgemäße Führungsschiene ist bspw. aus der AT 518 077 B1 bekannt.Such guide rails are used for drawer pull-out guides, so that a drawer can be pulled out relative to a furniture body when mounted. The drawer pull-out guides usually have a first guide rail to be fastened to a furniture body and at least one second guide rail which is mounted so that it can be displaced relative to the first guide rail. To realize a full extension of the drawer relative to the furniture body, a displaceably mounted third guide rail can also be arranged. Rolling bodies are provided for mounting the displaceable guide rails, which are mounted in a carriage or in several displaceable carriages. Specially shaped guide rails can improve the stability and load capacity of the drawer slide. When using large material thicknesses, the guide rails form a round angled area, as a result of which an increased installation space must also be provided. A generic guide rail is, for example AT 518 077 B1 known.

Aufgabe der Erfindung ist es, eine kompaktere Führungsschiene einer Schubladenausziehführung unter Vermeidung der oben diskutierten Nachteile anzugeben.The object of the invention is to specify a more compact guide rail for a drawer pull-out guide while avoiding the disadvantages discussed above.

Dies wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausführungen der Erfindung sind in den abhängigen Ansprüchen definiert.According to the invention, this is achieved by the features of claim 1 . Further advantageous embodiments of the invention are defined in the dependent claims.

Gemäß der Erfindung ist vorgesehen, dass der Abwinklungsbereich wenigstens eine sich entlang des Abwinklungsbereiches erstreckende und durch eine Ausnehmung gebildete Materialverjüngung aufweist.According to the invention, it is provided that the angled area has at least one tapered material that extends along the angled area and is formed by a recess.

Mit anderen Worten befindet sich in einem von den beiden Stegen der Führungsschiene eingeschlossenen Abwinklungsbereich (d.h. an einer Innenseite oder an einem Innenradius des Abwinklungsbereiches zwischen den beiden Stegen) wenigstens eine durch eine Ausnehmung gebildete Materialverjüngung mit verringerter Materialstärke, wobei die beiden Stege um eine in einer Längsrichtung der Ausnehmung verlaufende gedachte Achse zueinander abgewinkelt sind. Durch die durch die Ausnehmung gebildete Materialverjüngung wird eine durch Druckspannungen versursachte Stauchung an der Innenseite des Abwinklungsbereiches beim Biegen oder bei Profilieren verhindert, sodass die beiden Stege stärker zueinander abwinkelbar sind, beispielsweise dahingehend, dass die beiden Stege nicht nur einen Winkel von 90°, sondern auch einen Winkel von 180° relativ zueinander einnehmen können. Auf diese Weise kann der Abwinklungsbereich scharfkantiger ausgeführt und die Führungsschiene kompakter ausgeführt werden.In other words, in an angled area enclosed by the two webs of the guide rail (i.e. on an inner side or on an inner radius of the angled area between the two webs), there is at least one material taper formed by a recess with reduced material thickness, the two webs being one in one Longitudinally the recess extending imaginary axis are angled to each other. The material taper formed by the recess prevents compression caused by compressive stress on the inside of the angling area during bending or profiling, so that the two webs can be angled more strongly relative to one another, for example to the extent that the two webs are not only at an angle of 90°, but can also assume an angle of 180° relative to one another. In this way, the angled area can be made more sharp-edged and the guide rail can be made more compact.

Ein besonderer Vorteil der Erfindung liegt darin, dass durch die vorgeschlagene Maßnahme die für den Kontakt mit den Wälzkörpern vorgesehenen ebenen Laufflächen der Führungsschienen vergrößerbar sind, sodass - unter Beibehaltung der Größe der Führungsschiene - breitere Wälzkörper eingesetzt und damit die auftretenden Kräfte auf einen vergrößerten Bereich verteilt werden können. Auf diese Weise können die Stabilität und die Belastungskapazität der Schubladenausziehführung zusätzlich verbessert werden.A particular advantage of the invention is that the proposed measure can be used to enlarge the planar running surfaces of the guide rails provided for contact with the rolling elements, so that - while maintaining the size of the guide rail - wider rolling elements are used and the forces that occur are distributed over a larger area can become. In this way, the stability and the load capacity of the drawer slide can be further improved.

Erfindungsgemäß ist dabei vorgesehen, dass der erste Steg und/oder der zweite Steg eine vorgegebene erste Materialstärke aufweist oder aufweisen, wobei die durch die Ausnehmung gebildete Materialverjüngung des Abwinklungsbereiches eine gegenüber der ersten Materialstärke reduzierte zweite Materialstärke aufweist. Die Definition "erste Materialstärke" bezieht sich auf die Dicke des Ausgangsmaterials der Führungsschiene, ohne Berücksichtigung von allfälligen Prägungen oder Biegungen der Führungsschiene.According to the invention, it is provided that the first web and/or the second web has or have a predetermined first material thickness, the tapering of the material of the angled region formed by the recess having a second material thickness that is reduced compared to the first material thickness. The definition "first material thickness" refers to the thickness of the starting material of the guide rail, without taking into account any embossing or bending of the guide rail.

Die wenigstens eine Ausnehmung kann sich zumindest abschnittsweise, vorzugsweise im Wesentlichen über die gesamte Länge der Führungsschiene, in der Längsrichtung der Führungsschiene erstrecken. Dabei kann vorgesehen sein, dass die Ausnehmung als Rille ausgebildet ist.The at least one recess can extend at least in sections, preferably essentially over the entire length of the guide rail, in the longitudinal direction of the guide rail. It can be provided that the recess is designed as a groove.

Gemäß einem Ausführungsbeispiel kann vorgesehen sein, dass der erste Steg und der zweite Steg in einem Bereich außerhalb der Ausnehmung zumindest abschnittsweise aneinander anliegen. Dies ist insbesondere dann der Fall, wenn die beiden Stege in einem Winkel von 180° relativ zueinander abgewinkelt sind.According to one exemplary embodiment, it can be provided that the first web and the second web bear against one another at least in sections in a region outside the recess. This is particularly the case when the two webs are angled at an angle of 180° relative to one another.

Die erfindungsgemäße Schubladenausziehführung ist durch wenigstens eine Führungsschiene der in Rede stehenden Art gekennzeichnet. Die Schubladenausziehführung weist eine an einem Möbelkorpus zu befestigende erste Führungsschiene und zumindest eine relativ zur ersten Führungsschiene verschiebbar gelagerte zweite Führungsschiene auf, wobei zwischen der ersten Führungsschiene und der zweiten Führungsschiene zumindest ein Wälzkörper angeordnet ist, welcher am ersten Steg oder am zweiten Steg einer Führungsschiene abrollbar ist.The drawer pull-out guide according to the invention is characterized by at least one guide rail of the type in question. The drawer pull-out guide has a first guide rail to be fastened to a furniture body and at least one second guide rail that is mounted displaceably relative to the first guide rail, with at least one rolling element being arranged between the first guide rail and the second guide rail, which can roll on the first web or on the second web of a guide rail is.

Die erste Führungsschiene 9 weist zwei in Längsrichtung (L) voneinander beabstandete Befestigungsabschnitte 12a, 12b auf, durch welche die erste Führungsschiene 9 am Möbelkorpus 2 zu montieren ist. Zwischen der ersten Führungsschiene 9 und der zweiten Führungsschiene 10 ist zumindest ein erster Laufwagen 13 mit mehreren Wälzkörpern 14, 15 verschiebbar gelagert. Die Wälzkörper 14 sind in Längsrichtung (L) voneinander beabstandet und weisen jeweils eine in Montagelage horizontal verlaufende Drehachse auf, während die in Längsrichtung (L) voneinander beabstandeten Wälzkörper 15 jeweils eine in Montagelage vertikal verlaufende Drehachse aufweisen. Durch eine federunterstützte Einzugsvorrichtung 16 ist die dritte Führungsschiene 11 gegen Ende der Schließbewegung in die geschlossene Endlage einziehbar, wobei diese federunterstützte Schließbewegung durch eine Dämpfvorrichtung 17, beispielsweise in Form einer hydraulischen Kolben-ZylinderEinheit, dämpfbar ist. Figure 2a shows an exploded view of the drawer pull-out guide 4 with the first guide rail 9 (corpus rail) to be fastened to the furniture carcass 2, the third guide rail 11 (tray rail) to be connected to the drawer 3 and with the second guide rail 10 (middle rail), which is located between the first guide rail 9 and the third guide rail 11 is slidably mounted. The first guide rail 9 has two fastening sections 12a, 12b which are spaced apart from one another in the longitudinal direction (L) and by means of which the first guide rail 9 can be mounted on the furniture body 2. Between the first guide rail 9 and the second guide rail 10, at least one first carriage 13 with a plurality of rolling elements 14, 15 is slidably mounted. The rolling elements 14 are spaced apart in the longitudinal direction (L) and each have a horizontal axis of rotation in the assembled position, while the rolling elements 15 spaced apart from one another in the longitudinal direction (L) each have a vertical axis of rotation in the assembled position. By a spring-loaded retraction device 16 is the third Guide rail 11 can be retracted towards the end of the closing movement into the closed end position, this spring-assisted closing movement being dampable by a damping device 17, for example in the form of a hydraulic piston-cylinder unit.

Fig. 2b zeigt die Schubladenausziehführung 4 in einem Querschnitt, wobei der erste Laufwagen 13 mit den Wälzkörpern 14, 15 zwischen der ersten Führungsschiene 9 und der zweiten Führungsschiene 10 und zumindest ein zweiter Laufwagen 18 mit Wälzkörpern 14a, 15a zwischen der zweiten Führungsschiene 10 und der dritten Führungsschiene 11 verschiebbar gelagert ist. Die Wälzkörper 14a weisen jeweils eine in Montagelage horizontal verlaufende Drehachse auf, während die Wälzkörper 15a in Montagelage um eine vertikal verlaufende Drehachse rotierbar sind. Figure 2b shows the drawer pull-out guide 4 in a cross section, with the first carriage 13 with the rolling elements 14, 15 between the first guide rail 9 and the second guide rail 10 and at least one second carriage 18 with rolling elements 14a, 15a between the second guide rail 10 and the third guide rail 11 is slidably mounted. The rolling bodies 14a each have a horizontal axis of rotation in the installed position, while the rolling bodies 15a are rotatable about a vertical axis of rotation in the installed position.

Am Beispiel der zweiten Führungsschiene 10 wird nun die Erfindung näher erläutert. Die zweite Führungsschiene 10 weist einen ersten Steg 10a und zumindest einen zweiten Steg 10b auf, welche durch einen Abwinklungsbereich 23 miteinander verbunden sind, wobei der Abwinklungsbereich 23 zumindest eine sich entlang des Abwinklungsbereiches 23 erstreckende und durch eine Ausnehmung 21 gebildete Materialverjüngung aufweist. Der erste Steg 10a und/oder der zweite Steg 10b können jeweils eine vorgegebene erste Materialstärke aufweisen, während der von den beiden Stegen 10a, 10b eingeschlossene Abwinklungsbereich 23 mit wenigstens einer Ausnehmung 21 versehen ist, sodass der Abwinklungsbereich 23 eine gegenüber den Stegen 10a, 10b verringerte zweite Materialstärke aufweist. Wie aus der Fig. 2b erkennbar ist, können die Stege 10a, 10b durch das Vorhandensein der Ausnehmung 21 stärker zueinander abgewinkelt werden, ohne dass bei der Bearbeitung der zweiten Führungsschiene 10 an der Innenseite des Abwinklungsbereiches 23 wesentliche Druckspannungen auftreten. In der gezeigten Figur sind die Stege 10a, 10b in einem Winkel von 180° zueinander abgewinkelt. In einem Bereich außerhalb der Ausnehmung 21 können die beiden Stege 10a, 10b, vorzugsweise ohne Bildung eines Spaltes 19 (Fig.3a), zumindest abschnittsweise aneinander anliegen. Auf diese Weise kann die Bauhöhe der zweiten Führungsschiene 10, insbesondere bei mehreren übereinander angeordneten Stegen 10a, 10b, verringert werden. Die Führungsschiene 10 kann auch zwei oder mehrere durch Ausnehmungen 21, 21a, 21b gebildete Materialverjüngungen umfassen, wobei im gezeigten Ausführungsbeispiel die zu den Ausnehmungen 21a, 21b benachbarten Stege jeweils einen Winkel von annähernd 90° zueinander einnehmen.The invention will now be explained in more detail using the example of the second guide rail 10 . The second guide rail 10 has a first web 10a and at least one second web 10b, which are connected to one another by an angled area 23, the angled area 23 having at least one material taper extending along the angled area 23 and formed by a recess 21. The first web 10a and/or the second web 10b can each have a predetermined first material thickness, while the angled area 23 enclosed by the two webs 10a, 10b is provided with at least one recess 21, so that the angled area 23 has a relative to the webs 10a, 10b has a reduced second material thickness. How from the Figure 2b As can be seen, the webs 10a, 10b can be angled more strongly relative to one another due to the presence of the recess 21, without significant compressive stresses occurring on the inside of the angled region 23 when the second guide rail 10 is being machined. In the figure shown, the webs 10a, 10b are bent at an angle of 180° to one another. In an area outside the recess 21, the two webs 10a, 10b can preferably without forming a gap 19 ( Figure 3a ), at least partially touching each other. In this way, the overall height of the second guide rail 10 can be reduced, in particular in the case of a plurality of webs 10a, 10b arranged one above the other. The guide rail 10 can also comprise two or more material tapers formed by recesses 21, 21a, 21b, wherein in the exemplary embodiment shown, the material tapering to the recesses 21a, 21b adjacent webs each assume an angle of approximately 90° to one another.

Fig. 3a und Fig. 3b zeigen einen direkten Vergleich einer Führungsschiene 10 gemäß dem Stand der Technik (Fig. 3a) und einer erfindungsgemäßen Führungsschiene 10 (Fig. 3b). Die Führungsschiene 10 gemäß dem Stand der Technik in Fig. 3a weist eine konstante Materialstärke M1 auf, wobei die Stege 10a, 10b aufgrund der fehlenden Ausnehmung 21 unter Bildung eines Spaltes 19 in Höhenrichtung voneinander beabstandet sind. Dies führt auch zu einer Vergrößerung der Höhe (H) der Führungsschiene 10. Der Abwinklungsbereich 23 ist in Fig. 3a rund ausgebildet, außerdem stehen für die Wälzkörper 14, 15, 14a, 15a nur Laufflächen B, C mit einer relativ geringen Breite zur Verfügung. Figures 3a and 3b show a direct comparison of a guide rail 10 according to the prior art ( Figure 3a ) and a guide rail 10 according to the invention ( Figure 3b ). The guide rail 10 according to the prior art in Figure 3a has a constant material thickness M1, the webs 10a, 10b being spaced apart from one another in the height direction due to the lack of recess 21, forming a gap 19. This also leads to an increase in the height (H) of the guide rail 10. The angling area 23 is in Figure 3a formed around, are also for the rolling elements 14, 15, 14a, 15a only running surfaces B, C with a relatively small width.

Fig. 3b zeigt hingegen eine Ausführung der Führungsschiene 10 gemäß der Erfindung. Durch die Ausnehmungen 21, 21a, 21b ist die Materialstärke M2 gegenüber der Materialstärke M1 verringert, sodass die Stege 10a, 10b stärker zueinander abwinkelbar sind. Dies führt dazu, dass die Höhe H1 gemäß Fig. 3b geringer als die Höhe H gemäß Fig. 3a ist. Die geringere Höhe H1 führt also zu einer (erwünschten) reduzierten Bauhöhe der Führungsschiene 10. Außerdem ist erkennbar, dass die ebenen Laufflächen B1, C1 für die Wälzkörper 14, 15, 14a, 15a gemäß Fig. 3b gegenüber den ebenen Laufflächen B, C gemäß Fig. 3a deutlich vergrößert sind. Auf diese Weise können Wälzkörper 14, 15, 14a, 15a mit einer vergrößerten nominellen Breite verwendet werden, sodass eine verbesserte Abstützung der Führungsschienen 9, 10, 11 herbeigeführt und die Kräfte auf einen vergrößerten Bereich verteilbar sind. Die Ausnehmungen 21, 21a, 21b können in einem Querschnitt rechtwinklig zu einer Längsrichtung (L) der Führungsschiene 10 jeweils zumindest einen konkaven Abschnitt 22 aufweisen. Die scharfkantig ausgebildeten Abwinklungsbereiche 23 sind vorzugsweise durch Profilieren herstellbar. Das Profilieren (auch Walzprofilieren oder Kaltwalzen genannt) ist ein kontinuierliches Biegeverfahren, bei dem ein Materialstrang 20 (Fig. 4a) aus Metall in eine Profiliermaschine läuft, in welcher der Materialstrang 20 in vielen aufeinanderfolgenden Biegeoperationen durch Profilwalzrollen zum gewünschten Profilquerschnitt umgeformt wird. Figure 3b FIG. 12, however, shows an embodiment of the guide rail 10 according to the invention. Due to the recesses 21, 21a, 21b, the material thickness M2 is reduced compared to the material thickness M1, so that the webs 10a, 10b can be bent to a greater extent in relation to one another. This results in the height H1 according to Figure 3b less than the height H according to Figure 3a is. The lower height H1 thus leads to a (desired) reduced overall height of the guide rail 10. It can also be seen that the flat running surfaces B1, C1 for the rolling elements 14, 15, 14a, 15a according to FIG Figure 3b compared to the flat running surfaces B, C according to Figure 3a are significantly enlarged. In this way, rolling elements 14, 15, 14a, 15a with an increased nominal width can be used, so that improved support of the guide rails 9, 10, 11 is brought about and the forces can be distributed over an enlarged area. The recesses 21, 21a, 21b can each have at least one concave section 22 in a cross section perpendicular to a longitudinal direction (L) of the guide rail 10. The sharp-edged angled areas 23 can preferably be produced by profiling. Profiling (also called roll forming or cold rolling) is a continuous bending process in which a strand of material 20 ( Figure 4a ) made of metal runs into a profiling machine, in which the strand of material 20 is formed into the desired profile cross-section in many successive bending operations by profile rolling rollers.

Darüber hinaus kann vorgesehen sein, dass erste Steg 10a und der zweite Steg 10b der wenigstens einen Führungsschiene 10 eine unterschiedliche Länge aufweisen, wobei vorzugsweise vorgesehen ist, dass eine Länge des zweiten Steges 10b wenigstens dreimal so lang als eine Länge des ersten Steges 10a ist.According to the invention, it is provided that the at least one guide rail 10 has a section 24 that runs essentially vertically when the drawer pull-out guide 4 is installed, the first web 10a protruding in a first direction transversely, preferably essentially at right angles, from the vertically running section 24 of the guide rail 10 and that the second web 10b protrudes transversely, preferably essentially at right angles, from the vertically extending section 24 of the guide rail 10 in a second direction, opposite the first direction. In addition, it can be provided that the first web 10a and the second web 10b of the at least one guide rail 10 have different lengths, it being preferably provided that a length of the second web 10b is at least three times as long as a length of the first web 10a.
