The running roller rotatably located on the drawer side wall (12) in the furniture body interior end area has a slider component part (38) held longitudinally displaceably on the side wall between an inwardly drawn position and a withdrawn position over the rear wall of the drawer in the direction of the furniture rear wall.

Description

Die Erfindung betrifft eine mittels einer Rollen-Ausziehführung im Korpus eines Möbelstücks ausziehbar gelagerte Schublade, an deren Seitenwänden im korpusinneren rückwärtigen Endbereich jeweils wenigstens eine um eine rechtwinklig zur Ausziehrichtung und horizontal verlaufende Achse drehbar gelagerte Laufrolle vorgesehen ist, welche auf an der jeweils zugeordneten Korpuswand anbringbaren Führungsschienen vorgesehenen Laufbahnen abzurollen vermögen, wobei die Führungsschienen in ihrem korpusäußeren vorderen Endbereich jeweils wenigstens eine auf der zugeordneten Schubladen-Seitenwand ausgebildeten Laufbahn abrollende Laufrolle aufweisen.The invention relates to a drawer mounted by means of a roller pull-out guide in the body of a piece of furniture, on the side walls of which in the rear end region inside the body there is at least one castor mounted rotatably about an axis perpendicular to the direction of pulling out and horizontally, which can be attached to the respectively assigned body wall Guide rails are able to roll provided tracks, the guide rails each having at least one track roller rolling on the associated drawer side wall in their outer front end region of the body.

Derartige Schubladen, an deren Seitenwänden Laufbahnen für die Rollen-Ausziehführung integriert sind, sind bekannt. Insbesondere bei solchen Schubladen, bei denen die Schubladen im Stanz-Preßverfahren aus Metallblech ausgestanzte und gekantete Seitenwände haben, bietet es sich an, die Laufbahnen für die am vorderen Ende der Führungsschiene vorgesehene Laufrolle an der Schublade durch einen vom oberen Rand der Schubladen-Seitenwand umgekanteten und mit einem hieran anschließenden und nach unten umgekanteten Steg versehenen Materialstreifen zu bilden. Der Nachteil solcher Einfach-Rollenauszüge liegt darin, daß die Schublade nur soweit aus dem Korpusinnern herausgezogen werden kann, bis die am rückwärtigen Ende der Schubladen-Seitenwände vorgesehenen Laufrollen bis in Anlage an die am Vorderende der korpusfesten Führungsschiene vorgesehenen Laufrollen anstoßen. Dann befindet sich der rückwärtige Teil der Schublade aber noch im Schrankkorpus und dieser Bereich ist gegenüber Schubladen mit einem sog. Vollauszug, d.h. bei denen die Schublade ganz aus dem Korpus herausgezogen werden kann, schlechter zugänglich.Such drawers are known, on the side walls of which tracks for the roller pull-out guide are integrated. Particularly in such drawers, in which the drawers have punched-pressed metal sheet punched and folded sidewalls, it is advisable to run the tracks for the roller provided on the front end of the guide rail on the drawer by a folded from the upper edge of the drawer side wall and to form with a strip of material adjoining it and bent downwards. The disadvantage of such Single roller drawers are that the drawer can only be pulled out of the interior of the cabinet until the rollers provided at the rear end of the drawer side walls abut against the rollers provided at the front end of the body-fixed guide rail. Then the rear part of the drawer is still in the cabinet body and this area is less accessible than drawers with a so-called full extension, ie where the drawer can be pulled out of the body completely.

Vollauszüge erfordern in der Regel die Zwischenschaltung einer weiteren im Querschnitt Z-förmig ausgestalteten und ihrerseits mit Laufrollen versehenen Zwischenschiene. Das Gewicht, der technische Aufwand und die Kosten für einen derartigen Vollauszug steigen dann merklich.Full extensions generally require the interposition of a further intermediate rail with a Z-shaped cross section and in turn provided with castors. The weight, the technical effort and the costs for such a full extension then increase noticeably.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, die Rollen-Ausziehführung einer Schublade durch ihren hier in Frage stehenden Art mit einfachen und preisgünstigen Mitteln so weiterzubilden, daR die Schublade - entsprechend einer mit einem Vollauszug versehenen Schublade - ganz aus dem Korpusinnern herausgezogen werden kann.In contrast, the invention is based on the object of further developing the roller pull-out guide of a drawer by its type in question here with simple and inexpensive means so that the drawer can be pulled completely out of the interior of the body, corresponding to a drawer provided with a full extension.

Ausgehend von einer Schublade der eingangs erwähnten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die an der jeweils zugeordneten Schubladen-Seitenwand drehbar gelagerte Laufrollen im korpusinneren Endbereich eines seinerseits um eine vorgegebene Strecke in Ausziehrichtung zwischen einer nicht eingezogenen und einer über die Rückwand der Schublade in Richtung zur Korpus-Rückwand vortretenden ausgezogenen Stellung längsverschieblich an der Seitenwand gehalterten Schieber-Bauteil angeordnet ist. Durch die Möglichkeit den Schieber in die ausgezogene Stellung zu verschieben, welcher die an ihm vorgesehenen Laufrollen deutlich hinter der Schubladen-Rückwand liegt, ist es möglich, die Schublade um das Maß der Längsverschieblichkeit des Schiebers weiter herauszuziehen.Starting from a drawer of the type mentioned at the outset, this object is achieved according to the invention in that the rollers which are rotatably mounted on the respectively associated drawer side wall in the end region of the interior of the body are themselves a predetermined distance in the direction of extension between a non-retracted and one over the rear wall of the drawer in Direction to the body rear wall protruding extended position is arranged longitudinally displaceably mounted slide member. Due to the possibility to move the slide into the extended position, which is the rollers on it clearly behind the drawer rear wall, it is possible to pull out the drawer to further extend the length of the slide.

Der jeweilige Schieber-Bauteil weist dabei zweckmäßig eine in einen zum korpusinneren Ende offenen Ausschnitt oder eine Vertiefung der Seitenwand angeordnete, den Ausschnitt bzw. die Vertiefung im wesentlichen passend ausfüllende Lagerplatte auf, an welcher die Laufrolle drehbar gelagert ist, und an der Lagerplatte ist dann ein flacher Führungsschieber angesetzt, welcher in paralleler Anlage längsverschieblich an der Seitenwand, und zwar vorzugsweise auf der zur zugeordneten Korpuswand weisenden Außenseite der jeweiligen Seitenwand geführt gehalten ist.The respective slide component expediently has a bearing plate which is arranged in a cutout or a recess in the side wall which is open towards the inside of the body and essentially fills out the cutout or the recess and on which the roller is rotatably mounted and is then on the bearing plate a flat guide slide is attached, which is held in a parallel arrangement in a longitudinally displaceable manner on the side wall, preferably on the outside of the respective side wall facing the associated body wall.

Für die Halterung des Führungsschiebers können wenigstens zwei in Ausziehrichtung der Schublade voneinander beabstandete, den Führungsschieber passend übergreifende und an der Seitenwand befestigte Führungsbügel vorgesehen sein.At least two guide brackets, which are spaced apart from one another in the pull-out direction of the drawer, fit over the guide slide and are fastened to the side wall, can be provided for holding the guide slide.

Um zu verhindern, daß der Führungsschieber bei dieser Art und Weise der Halterung aus den Führungsbügeln herausgezogen werden und somit die Schublade abstürzen kann, empfiehlt es sich, am lagerplattenabgewandten Ende des Führungsschiebers einen zur Korpuswand vortretenden und in der nach rückwärts ausgezogenen Stellung am vorderen Führungsbügel zur Anlage kommenden Anschlag vorzusehen.In order to prevent the guide slide from being pulled out of the guide brackets in this way of the holder and thus causing the drawer to fall off, it is advisable to use one end on the front guide bracket that protrudes towards the body wall and in the rearwardly extended position on the end of the guide slide To provide for the upcoming stop.

Dieser Anschlag kann dabei vom Kopf einer mit ihrem kurzen Schaft in eine Gewindebohrung der Führungsschiene eingeschraubten Schraube gebildet sein. Das hat den Vorteil, daß die Führungsschieber nach Herausschrauben dieser den Anschlag bildenden Schraube ohne weiteres von der Schubladenseitenwand durch Herausziehen aus den Führungsbügeln demontiert werden können.This stop can be formed by the head of a screw with its short shaft screwed into a threaded hole in the guide rail. This has the advantage that after unscrewing this screw forming the stop, the guide slides can be easily removed from the side wall of the drawer by pulling them out of the guide brackets.

Der Führungsschieber kann alternativ auch in einer seiner Breite und Tiefe entsprechend bemessenen langgestreckten Sicke in der Schubladen-Seitenwand selbst geführt sein, wobei dann - z.B. durch kurze, die seitenwandabgewandte Seite der Führungsbügel übergreifende Lappen - Sorge dafür getragen sein muß, daß die Führungsbügel nicht rechtwinklig zur Ausziehrichtung aus der Sicke austreten können.Alternatively, the guide slide can also have an elongated length that is dimensioned in accordance with its width and depth Bead in the drawer side wall itself, whereby then - for example by short, the side wall remote side of the guide bracket rag - care must be taken to ensure that the guide bracket can not exit at right angles to the direction of pulling out of the bead.

Von Vorteil ist weiterhin eine Ausgestaltung, bei der im Schieber-Bauteil eine unter Vorspannung stehende Feder direkt oder indirekt angreift, welche ihn in die eingezogene Lage vorspannt, in welcher die Lagerplatte im Ausschnitt der Seitenwand steht.Another advantage is an embodiment in which a spring under tension biases directly or indirectly in the slide component, which biases it into the retracted position in which the bearing plate is in the cutout of the side wall.

Dabei wird die von der Feder auf den Schieber-Bauteil ausgeübte Vorspannkraft zweckmäßig größer als die den ausgezogenen Schieber-Bauteil in der ausgezogenen Stellung zu halten suchenden Reibungskräfte zwischen dem Schieberbauteil und den ihn verschieblich halternden Bauteilen bemessen. Bezüglich des durch den Schieber-Bauteil zusätzlich zur Verfügung gestellten Auszugweges ist die Schublade dann selbsteinziehend. Wenn andererseits dann noch der übliche Selbsteinzug durch Veränderung der Neigung der Führungsschiene an ihrem inneren Ende vorgesehen wird, ist die Schublade auch insgesamt bei Annäherung an die Schließstellung selbsteinziehend.The prestressing force exerted by the spring on the slide component is expediently greater than the frictional forces between the slide component and the components which hold it displaceably in order to keep the extended slide component in the extended position. The drawer is then self-retracting with regard to the extension path additionally provided by the slide component. If, on the other hand, the usual self-retraction is then provided by changing the inclination of the guide rail at its inner end, the drawer is also self-retracting as it approaches the closed position.

Um zu verhindern, daß sich die Schublade im ganz ausgezogenen Zustand von selbst um das Maß des Schieberauszugs zurückzieht, kann eine Rasteinrichtung vorgesehen sein, welche den Schieber-Bauteil in der ganz ausgezogenen Stellung hält, die dann aber beim Einschieben der Schublade durch einen kurzen Druck auf die Schubladen-Frontblenden ausgerastet wird, worauf die Vorspannung der am Führungsschieber angreifenden Feder wirksam wird und den Schieber einzieht.In order to prevent the drawer from retracting itself by the amount of the slide extension in the fully extended state, a latching device can be provided which holds the slide component in the fully extended position, but which is then pushed in by a short pressure when the drawer is pushed in is released on the drawer front panels, whereupon the pretension of the spring acting on the guide slide takes effect and pulls in the slide.

Die Erfindung ist in der folgenden Beschreibung eines Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert, und zwar zeigt:

In Fig. 2 sind die zusammenwirkenden Teile einer Rollen-Ausziehführung 10 für Schubladen gezeigt, bei welchen die Funktion der schubladenseitigen Laufschiene in die - im gezeigten Fall - im Stanz-Preß-Verfahren aus Metall hergestellte Schubladen-Seitenwand 12 integriert ist. Die an der zugeordneten Korpuswand zu montierende Führungsschiene 14 ist dagegen konventionell ausgebildet. Konventionell heißt in diesem Fall, daß die Führungsschiene als mit ihrer Stegfläche 16 an der zugeordneten Korpuswand anliegend befestigbare, im Querschnitt etwa U-förmige Profilschiene ausgebildet ist, deren von der Stegfläche 16 vortretenden, von den U-Schenkeln gebildeten Profilschenkel 18a, 18b in Richtung zur Schubladen-Seitenwand 12 vortreten und Laufbahnen für eine am korpusinneren Ende der Schubladen-Seitenwand drehbar gelagerte Laufrolle 20 bilden. Am korpusäußeren, zu einem ebenflächigen Befestigungsflansch 22 vergrößerten Vorderende der Führungsschiene ist dann eine zweite Laufrolle 24 drehbar gelagert, auf welcher die an der Schubladen-Seitenwand 12 vorgesehene Laufbahn der Schublade abrollt. Diese Laufbahn wird im dargestellten Fall von einem etwa rechtwinklig vom oberen Rand der Schubladen-Seitenwand abgewinkelten streifenförmigen Profilschenkel 26 gebildet, von dessen seitenwandabgewandtem Rand noch ein niedriger streifenförmiger Profilschenkel 28 nach unten umgekantet ist, welcher einerseits die Laufrolle 24 der Tragschiene an der seitenabgewandten Seite umgreift und andererseits den oberen Rand der Schubladen-Seitenwand insgesamt versteift und stabilisiert.2 shows the interacting parts of a roller pull-out guide 10 for drawers, in which the function of the slide rail on the drawer side is integrated into the drawer side wall 12, which is made of metal in the stamping-pressing process, in the case shown. In contrast, the guide rail 14 to be mounted on the associated body wall is of conventional design. Conventional in this case means that the guide rail is designed as a profile rail which is approximately U-shaped in cross-section and can be fastened with its web surface 16 against the associated body wall, the profile legs 18a, 18b of the U-legs which project from the web surface 16 in the direction Step forward to the drawer side wall 12 and form raceways for a roller 20 which is rotatably mounted on the inside end of the drawer side wall. A second roller 24 is then rotatably mounted on the outer front end of the guide rail, enlarged to form a flat fastening flange 22, on which the path of the drawer provided on the drawer side wall 12 rolls. In the case shown, this track is formed by a strip-shaped profile leg 26 angled approximately at right angles from the upper edge of the drawer side wall, from the edge facing away from the side wall, a lower strip-shaped profile leg 28 is folded downward, which on the one hand engages around the roller 24 of the mounting rail on the side facing away from the side and on the other hand stiffens and stabilizes the upper edge of the drawer side wall as a whole.

Vom unteren Rand der Schubladen-Seitenwand 12 ist ebenfalls ein streifenförmiger Profilschenkel 30 in entgegengesetzte Richtung, d.h. von der zugeordneten Korpuswand weg rechtwinklig umgekantet, der neben der Versteifung der Seitenwand 12 gleichzeitig zur Auflagerung des - nicht gezeigten - Schubladen-Bodens dient. Aus diesem Profilschenkel 30 freigeschnittene und hochgekantete, in eine Nut oder Ausnehmungen im Schubladen-Boden eingreifende Lappen 32 dienen zur Festlegung des Schubladen-Bodens auf dem Profilschenkel 30. Im korpusäußeren Endbereich der Schubladen-Seitenwand 12 ist etwa in halber Höhe der seitenwandseitige Teil 34 eines Verbindungsbeschlages angeordnet, an welchen ein zweiter - nicht gezeigter - Beschlagteil befestigbar ist, der von der Innenfläche einer zugeordneten Schubladen-Frontblende vortritt. Im bisher beschriebenen Umfang ist die Rollen-Ausziehführung bekannt.From the lower edge of the drawer side wall 12 is also a strip-shaped profile leg 30 in the opposite direction, i.e. folded away from the associated body wall at a right angle, which, in addition to stiffening the side wall 12, also serves to support the drawer bottom (not shown). From this profile leg 30 cut and edged, engaging in a groove or recesses in the drawer bottom tabs 32 are used to fix the drawer bottom on the profile leg 30. In the outer end region of the drawer side wall 12 is about half the height of the side wall part 34 one Connection fitting arranged, to which a second - not shown - fitting part can be fastened, which protrudes from the inner surface of an associated drawer front panel. To the extent described so far, the roller pull-out guide is known.

Gegenüber dem Stand der Technik abgewandelt erfolgt die drehbare Lagerung der Laufrolle 20 nicht direkt an der Schubladen-Seitenwand 12', sondern an einem Schieber-Bauteil 38, welcher in Ausziehrichtung der Schublade längsverschieblich an der Schubladen-Seitenwand 12 gehaltert ist, und zwar zwischen einer eingezogenen ersten Stellung, in welcher die Lage der Laufrolle 20 der Lage solcher Laufrollen an der Seitenwand 12 bei üblichen Rollen-Ausziehführungen entspricht, und einem in Fig. 1 dargestellten und in Fig. 2 zusätzlich strichpunktiert veranschaulichten Stellung, in welcher die Laufrolle 20 dem über die Rückwand der Schublade in Richtung zur Korpus-Rückwand vortretend ausgezogen ist.Modified compared to the prior art, the rotatable mounting of the roller 20 does not take place directly on the drawer side wall 12 ', but on a slide component 38 which is mounted on the drawer side wall 12 so as to be longitudinally displaceable in the pull-out direction of the drawer, namely between one retracted first position, in which the position of the roller 20 corresponds to the position of such rollers on the side wall 12 in the case of conventional roller pull-out guides, and a position shown in FIG. 1 and additionally shown in dash-dotted lines in FIG. 2, in which the roller 20 over the the rear wall of the drawer is pulled out towards the body rear wall.

Der Schieber-Bauteil 38 setzt sich im dargestellten Fall aus einer Lagerplatte 40 und einem an der Lagerplatte angesetzten flachen langgestreckten Führungsschieber 42 zusammen, welcher in paralleler Anlage längsverschieblich an der Seitenwand 12 gehalten ist. Die Lagerplatte 40 ihrerseits steht in der ersten eingezogenen Stellung in einem zum korpusinneren Ende und nach oben offenen Ausschnitt 44 der Schubladen-Seitenwand 12 und sie ist so bemessen, daß sie diesen Ausschnitt in der eingezogenen Stellung des Schieber-Bauteils 38 ausfüllt, wobei der Ausschnitt auch durch eine zur Korpus-Rückwand hin offene die Lagerplatte in der eingezogenen Stellung passend aufnehmende Vertiefung ersetzt sein kann. Wenn die Lagerplatte 40 zur Ebene der Seitenwand parallel versetzt am Führungsschieber 42 angeordnet ist, kann der Ausschnitt 44 oder die Vertiefung auch entfallen.In the case shown, the slide component 38 is composed of a bearing plate 40 and a flat, elongated guide slide 42 which is attached to the bearing plate and which is held on the side wall 12 in a longitudinally displaceable manner in parallel contact. The bearing plate 40 in turn is in the first retracted position in a cutout 44 of the drawer side wall 12 which is open towards the inside of the body and upwards and is dimensioned such that it fills out this cutout in the retracted position of the slide component 38, the cutout can also be replaced by an open to the body back wall open the bearing plate in the retracted position suitably receiving recess. If the bearing plate 40 is arranged offset parallel to the plane of the side wall on the guide slide 42, the cutout 44 or the recess can also be omitted.

Der flache langgestreckte Führungsschieber 42 ist auf der zur Korpuswand weisenden Außenseite der Seitenwand 12 anliegend gehalten, wobei er von wenigstens zwei in Ausziehrichtung der Schublade zueinander beabstandeten, den Führungsschieber 42 passend übergreifenden und an der Seitenwand befestigten Führungsbügeln 46a, 46b geführt ist. Am lagerplattenabgewandten vorderen Ende des Führungsschiebers ist ein Anschlag in Form des Kopfs einer in eine Gewindebohrung im Führungsschieber 42 eingeschraubten Schraube 48 vorgesehen, welche verhindert, daß der Führungsschieber 42 und somit der Schieber-Bauteil 38 insgesamt ungewollt aus den Führungsbügeln 46b, 46a herausgezogen werden kann. Für die Montage und bei einer eventuellen Demontage des Schieber-Bauteils 38 ist die Schraube 48 aber herausdrehbar.The flat, elongated guide slide 42 is held against the outside of the side wall 12 facing the body wall, being guided by at least two guide brackets 46a, 46b which are spaced apart from one another in the pull-out direction of the drawer and fit over the guide slide 42 and are fastened to the side wall. At the front end of the guide slide facing away from the bearing plate, a stop in the form of the head of a screw 48 screwed into a threaded bore in the guide slide 42 is provided, which prevents the guide slide 42 and thus the slide component 38 as a whole from being unwantedly pulled out of the guide brackets 46b, 46a . However, the screw 48 can be unscrewed for assembly and for possible disassembly of the slide component 38.

Durch eine am Führungsschieber 42 einerseits und an der Schubladen-Seitenwand 12 andererseits angeschlossene langgestreckte, unter Zugvorspannung stehende Feder 50 ist der Schieber-Bauteil 38 in die eingezogene Stellung vorgespannt, wobei die Vorspannung der Feder aber lediglich so groß bemessen ist, daß sie die Reibung zwischen dem Führungsschieber 42 und den ihnen halternden Führungsbügeln 46a, 46b überwindet, einer bewußt auf die Schublade ausgeübten Ausziehkraft aber kein größeren Widerstand entgegensetzt, so daß also der vom Schieber-Bauteil zur Verfügung gestellte zusätzliche Auszugsweg ohne Kraftanstrengung der die Schublade ausziehenden Person realisierbar ist.The slide component 38 is biased into the retracted position by an elongated spring 50 connected to the guide slide 42 on the one hand and to the drawer side wall 12 on the other hand, which is under tension. the prestressing of the spring is, however, only so large that it overcomes the friction between the guide slide 42 and the guide brackets 46a, 46b holding it, but does not oppose a pulling force deliberately exerted on the drawer, so that the slide Component provided additional extension path can be realized without the effort of the person pulling out the drawer.

Dabei kann es sinnvoll sein, zwischen dem Schieber-Bauteil und der Schubladen-Seitenwand eine in der ganz ausgezogenen Stellung des Schieber-Bauteils wirksam werdende (nicht gezeigte) Rasteinrichtung vorzusehen, welche verhindert, daß eine ganz ausgezogene Schublade nach dem Loslassen des Schubladengriffs sich unter dem Einfluß der Vorspannung der Feder 50 um das Verschiebungsmaß des Schieber-Bauteils 38 selbsttätig einzieht. Beim Schließen der Schublade durch Einschieben ins Korpusinnere kann die Rastvorrichtung dann beim Anfahren der Laufrolle 20 an den Endanschlägen der Führungsschiene 14 durch einen kurzen Druck in Einschubrichtung entrastet werden und die Feder 50 zieht die Schublade dann in die ganz geschlossene Stellung ein.It may be useful to provide a locking device (not shown) that becomes effective in the fully extended position of the slide component between the slide component and the drawer side wall, which prevents a fully extended drawer from underneath after the drawer handle is released the influence of the bias of the spring 50 automatically moves by the amount of displacement of the slide member 38. When closing the drawer by pushing it into the interior of the body, the latching device can then be unlocked by a short pressure in the direction of insertion when the roller 20 approaches the end stops of the guide rail 14 and the spring 50 then pulls the drawer into the fully closed position.

Es ist ersichtlich, daß im Rahmen des Erfindungsgedankens Abwandlungen und Weiterbildungen des beschriebenen Ausführungsbeispiels verwirklichbar sind. So ist die Art und Weise der Lagerung des Führungsschiebers 42 auch in anderer Weise verwirklichbar. Anstelle der beschriebenen Führungsbügel 46a, 46b kann auch die Führung für den Führungsschieber 42 durch Einformen einer passenden Sicke in die Schubladen-Seitenwand integriert werden. Zur Verringerung der zwischen dem Führungsschieber 42 und seiner Halterung auftretenden Reibungskräfte können entsprechende reibungsvermindernde Maßnahmen getroffen werden. Hier ist an eine entsprechende Behandlung der aufeinandergleitenden Flächen durch Politur oder Beschichtung bzw. Auflagen aus reibungsmindernden Kunststoffen oder auch eine Lagerung des Führungsschiebers in Rolkörpern zu denken.It can be seen that modifications and developments of the exemplary embodiment described can be implemented within the scope of the inventive concept. The manner in which the guide slide 42 is supported can also be realized in another way. Instead of the described guide brackets 46a, 46b, the guide for the guide slide 42 can also be integrated into the drawer side wall by molding a suitable bead. Corresponding friction-reducing measures can be taken to reduce the frictional forces occurring between the guide slide 42 and its holder. Appropriate treatment of the surfaces sliding on one another is required here by polishing or coating or by means of anti-friction coatings Plastics or storage of the guide slide in roller bodies.
