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.

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
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.

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.

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.

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.
