Abstract

A drawer telescopic guiding device (10) has a guiding rail (32) shaped as a profiled rail and a running rail (16) which can be moved relative to each other by at least one respective roller (48;28) rotatably mounted at the front end of the guiding rail (32) and at the back end of the running rail (16), seen in the direction of extension, on a profiled branch of the other rail. The guiding rail (32) has an approximately U-shaped cross-section; its profiled branches (36; 38) formed by the U branches that extend above its web surface (34) extend beyond the running rail roller (28) in the cross-sectional direction, partly enclosing it on its side facing away from the guiding rail web. The profiled branch (20) of the running rail (16) that forms the running path also extends with its free edge beyond the guiding rail roller (48), partly enclosing it. The inner width, measured between the web surface (34) and the edge (40; 42) enclosing the running rail roller (28), of at least one, preferably both profiled branches (36; 38) of the guiding rail (32) gradually diminishes from the inside of the body towards the totally drawn-out position, in the region crossed by the running rail roller (28) when it approaches the totally drawn out position.

Description

Die Erfindung betrifft eine Ausziehführung für Schubladen u.dgl. ausziehbare Möbelteile mit einer an der Tragwand eines Möbelkorpus befestigbaren, als Profilschiene ausgebildeten Führungsschiene und einer am ausziehbaren Möbelteil befestigbaren profilierten Laufschiene, die durch jeweils wenigstens eine an dem in Ausziehrichtung vorderen Ende der Führungsschiene und dem rückwärtigen Ende der Laufschiene drehbar gelagerte auf einem Profilschenkel der jeweils anderen Schiene ablaufende Rolle relativ zueinander verschiebbar sind, wobei die Führungsschiene als mit ihrer Stegfläche an der Tragwand anliegend befestigte im Querschnitt etwa U-förmige Profilschiene ausgebildet ist, deren von der Stegfläche vortretende, von den U-Schenkeln gebildete Profilschenkel die Laufschienen-Rollen in Querrichtung überragen und auf der tragwandabgewandten Seite noch etwas umgreifen, und auch der die Laufbahn der Laufschiene bildende Profilschenkel die Führungsschienen-Rollen mit seinem dem ausziehbaren Möbelteil abgewandten freien Rand überragt und etwas umgreift.The invention relates to a pull-out guide for drawers and the like. Extendable furniture parts with a guide rail that can be attached to the supporting wall of a furniture body, designed as a profile rail, and a profiled guide rail that can be attached to the extendable furniture part, each of which has at least one on the profile leg of the guide rail, which is rotatably mounted on the front end in the pull-out direction and the rear end of the guide rail other rail-running roller are displaceable relative to each other, the guide rail being designed as a cross-sectionally U-shaped profile rail attached with its web surface to the support wall, the profile leg of the web surface formed by the U-legs forming the running rail rollers in the transverse direction protrude and grip around on the side facing away from the supporting wall, and also the profile leg forming the running track of the running rail projects beyond the guide rail rollers with its free edge facing away from the pull-out furniture part and somewhat embraces.

Ausziehführungen, die mit je einer Rolle an einem Ende der Führungs- und der Laufschiene versehen sind, und deshalb auch als "Rollenauszüge" bezeichnet werden, haben sich in paarweiser Verwendung an gegenüberliegenden Seiten von Schubladen, ausziehbaren Arbeitsplatten, Geräteträgern u.dgl. wegen der im Vergleich zu Gleitführungen geringeren erforderlichen Auszugskraft in zunehmendem Maß eingeführt. Bei der Fertigung von Möbeln kommt es nun immer wieder zu Toleranzen in den Breitenabmessungen der Schubladen bzw. im lichten Innenabstand zwischen den Tragwänden des Möbelkorpus. Diese Toleranzen beeinträchtigen die Funktion der Auszüge nicht, weil wenigstens eines der Paare von Ausziehführungen die hieraus resultierenden seitlichen Versetzungen der Rollen auf den zugeordneten Profilschenkeln gestattet, wobei dann jedoch seitliche Versetzungen der Schublade quer zur Ausziehrichtung zumindest dann möglich sind, wenn solche seitlichen Versetzungen an beiden Ausziehführungen möglich sind. Dann kann es beispielsweise dazu kommen, daß die senkrechten Begrenzungskanten der sichtbaren Schubladenblenden mehrerer übereinander angeordneter Schubladen nicht mehr exakt fluchten, was ein unschönes Bild ergibt. Außerdem wird die Seitenführung der Schublade verschlechtert, und zwar um so stärker, je weiter die Schublade herausgezogen ist. Eine gans herausgezogene Schublade hat wegen des dann geringen Abstandes der Rollen der Führungs- und der Laufschiene voneinander im Bereich der Schubladenblende in Querrichtung ein Spiel, welches erheblich sein kann. Um dieses Querspiel zu beheben, ist eine Anlenkung von Schubladen mit zwei unterschiedlichen Ausziehführungen auf den gegenüberliegenden Seiten der Schubladen bekannt, und zwar sind die den Rollen zugeordneten Profilschenkel der Schienen einer Ausziehführung so ausgebildet, daß sie die Rollen noch umgreifen, so daß die seitliche Versetzung der Rollen auf den zugehörigen Profilschenkeln verringert ist. Die Breitentoleranz der Schubladen bzw. des lichten Innenabstands der Möbeltragwände wird dann im wesentlichen an der gegenüberliegenden Ausziehführung wirksam, bei welcher die Rollen umgreifenden Profilschenkel nicht verwendet werden. Allerdings wird durch die die Rollen umgreifenden Profilschenkel das Querspiel nicht völlig beseitigt, weil zur Gewährleistung eines leichten und hemmungsfreien Laufs der Rollen die Breite der Profilschenkel mit einem gewissen Übermaß bemessen werden muß und die Profilschenkel selbst auch nicht rechtwinklig und scharfkantig von den Stegflächen der Führungs- bzw. Laufschiene abgekantet werden. Zwischen den Stegflächen der Schienen und der zugewandten Flachseite der Rolle an der jeweils anderen Schiene verbleibt deshalb ein  ―  bewußt vorgesehener  ―  Zwischenraum für die Köpfe von Befestigungsschrauben, mit denen die Schiene an der Tragwand bzw.  ― in manchen Fällen  ―  auch an der Schubladen-Seitenwand befestigt wird. Außerdem ist dieser Zwischenraum dann auch für den die jeweilige Rolle umgreifenden Rand des Profilschenkels der jeweils anderen Schiene erforderlich. In ganz herausgezogenem Zustand sind deshalb  ―  auch wegen des erwähnten kurzen Rollenabstandes  ―  mit derartigen Ausziehführungen gelagerte Schubladen labil.Pull-out guides, which are each provided with a roller at one end of the guide rail and the running rail, and are therefore also referred to as "roller pull-outs", have been used in pairs on opposite sides of drawers, pull-out worktops, equipment carriers and the like. introduced due to the lower pull-out force required compared to sliding guides. When manufacturing furniture, there are always tolerances in the width dimensions of the drawers or in the clear internal clearance between the supporting walls of the furniture body. These tolerances do not affect the function of the pull-outs, because at least one of the pairs of pull-out guides allows the resulting lateral displacements of the rollers on the associated profile legs, but then lateral displacements of the Drawer transverse to the pull-out direction are at least possible if such lateral displacements on both pull-out guides are possible. Then it can happen, for example, that the vertical boundary edges of the visible drawer panels of a plurality of drawers arranged one above the other are no longer exactly aligned, which results in an unsightly picture. In addition, the side guidance of the drawer is deteriorated, and the more the more the drawer is pulled out, the worse. A drawer that is pulled out has a play in the transverse direction due to the then small distance between the rollers of the guide rail and the running rail, which can be considerable. In order to remedy this cross-game, a linkage of drawers with two different pull-out guides on the opposite sides of the drawers is known, namely the profile legs of the rails of a pull-out guide assigned to the rollers are designed such that they still grip around the rollers, so that the lateral displacement the roles on the associated profile legs is reduced. The width tolerance of the drawers or the clear internal spacing of the furniture support walls is then essentially effective on the opposite pull-out guide, in which the profile arms encompassing the rollers are not used. However, the transverse play is not completely eliminated by the profile legs encompassing the rollers because, in order to ensure that the rollers run smoothly and uninhibitedly, the width of the profile legs must be dimensioned with a certain excess and the profile legs themselves are also not rectangular and sharp-edged from the web surfaces of the guide or track are folded. Between the web surfaces of the rails and the facing flat side of the roller on the other rail, therefore, there is a - deliberately provided - space for the heads of fastening screws with which the rail on the support wall or - in some cases - also on the drawer side wall is attached. In addition, this gap is then also required for the edge of the profile leg of the respective other rail encompassing the respective role. When fully pulled out, drawers mounted with such pull-out guides are therefore unstable, also because of the short roller spacing mentioned.

In der US-A-4315661 sind bei einer Ausziehführung in den Schienen nach außen vorstehende Vorsprünge in Form von Wülsten parallel zu den Profilschenkeln angeordnet. Sie sollen das Querspiel reduzieren, indem sie eine Annäherung der Laufrollen an die Stegfläche der Schienen verhindern. Auch hier verbleibt zwischen den umgreifenden Rändern der Schienen und der zugewandten Flachseite der Rolle an der jeweils anderen Schiene ein Zwischenraum, um den leichten und hemmungsfreien Lauf der Rollen zu gewährleisten. Auch die Ausziehführungen nach diesem Vorbild sind daher in ganz herausgezogenem Zustand der Schublade im Bereich der Schubladenblende labil.In US-A-4315661, in the case of a pull-out guide in the rails, protruding projections in the form of beads are arranged parallel to the profile legs. They are intended to reduce the transverse play by preventing the rollers from approaching the web surface of the rails. Here, too, there is a space between the encompassing edges of the rails and the flat side of the roller facing the other rail in order to ensure that the rollers run smoothly and freely. The pull-out guides based on this model are therefore unstable when the drawer is fully pulled out in the area of the drawer cover.

Eine andere Ausziehführung ist aus der GB-A-2140282 bekannt geworden. Dort werden seitliche Versetzungen der Schublade quer zur Ausziehrichtung dadurch behoben, daß die Rollen an ihren Stirnseiten jeweils mit Kegelflächen versehen sind, die in entsprechenden V-förmigen Führungsbahnen laufen. Die Breitentoleranz der Schublade bzw. des lichten Innenabstands der Möbeltragwände kann dann nicht mehr zwischen Rolle und Führungsbahn wirksam werden. Sie wird durch eine nachgiebige Befestigung einer Tragschiene an einer Tragwand ausgeglichen.Another pull-out guide has become known from GB-A-2140282. There, lateral displacements of the drawer transversely to the pull-out direction are eliminated in that the rollers are each provided on their end faces with conical surfaces which run in corresponding V-shaped guideways. The width tolerance of the drawer or the clear internal clearance of the furniture support walls can then no longer be effective between the roller and the guideway. It is compensated for by a flexible attachment of a mounting rail to a mounting wall.

Der Lauf der Kegelflächen auf den schrägen Seitenwänden der V-förmigen Führungsbahnen verursacht jedoch Reibung, die den leichten und hemmungsfreien Lauf der Rollen behindert. Bei großem Übermaß des Tragwandabstandes bzw. Untermaß der Schublade ist diese Reibung erheblich, da dann über die Kegelflächen und schrägen Seitenwände der Führungsbahnen erhebliche Kräfte in die nachgiebige Befestigung eingeleitet werden müssen.However, the running of the tapered surfaces on the sloping side walls of the V-shaped guideways causes friction, which hinders the easy and unrestricted running of the rollers. If the distance between the supporting walls or the undersize of the drawer is large, this friction is considerable. since considerable forces must then be introduced into the flexible fastening via the conical surfaces and sloping side walls of the guideways.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Ausziehführung für Schubladen u.dgl. zu schaffen, welches das in ganz herausgezogenem Zustand vorhandene Querspiel wesentlich verringert, ohne den leichten Lauf der Ausziehführung zu beeinträchtigen.In contrast, the invention has for its object a pull-out guide for drawers and the like. to create, which significantly reduces the existing cross play when fully pulled out, without impairing the smooth running of the pull-out guide.

Ausgehend von einer Ausziehführung der eingangs erwähnten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die zwischen der Stegfläche und dem die die Laufschienen-Rolle umgreifenden Rand gemessene lichte Breite wenigstens eines der, vorzugsweise beider Profilschenkel der Führungsschiene in dem bei Annäherung an die ganz ausgezogene Stellung von der Laufschienen-Rolle überfahrenen Bereich sich vom Korpusinnern aus in Richtung auf die ganz ausgezogene Stellung allmählich verringert. Dies hat zur Folge, daß das Querspiel gerade im kritischen, ganz ausgezogenen Bereich der Schublade bereits deutlich verringert wird, weil ein geringeres seitliches Spiel der Laufrollen bezüglich der sie umgreifenden Profilschenkel besteht. Festzuhalten ist dabei, daß die in der erfindungsgemaßen Weise ausgestaltete Ausziehführung nur an einer Seite einer Schublade oder eines anderen ausziehbaren Teils vorzusehen ist, während die zweite Ausziehführung in der üblichen Weise, d.h. ohne die Laufrollen umgreifende Profilschenkel ausgestaltet ist.Starting from a pull-out guide of the type mentioned at the outset, this object is achieved according to the invention in that the clear width measured between the web surface and the edge encompassing the running rail roller at least one of the, preferably both, profile legs of the guide rail in the position when the fully extended position is approached the area run over by the roller track gradually decreases from the inside of the body towards the fully extended position. This has the consequence that the transverse play is already significantly reduced in the critical, fully extended area of the drawer, because there is less lateral play of the rollers with respect to the profile legs encompassing them. It should be noted here that the pull-out guide designed in the manner according to the invention is only to be provided on one side of a drawer or another pull-out part, while the second pull-out guide in the usual way, i.e. is designed without profile legs encompassing the rollers.

In weiterer Ausgestaltung der Erfindung ist es zweckmäßig, wenn in dem der ganz ausgezogenen Stellung der Laufschienen-Rolle gegenüberliegenden Bereich der Stegfläche der Führungsschiene wenigstens eine zur Rolle vortretende flache Erhebung vorgesehen ist, welche also den zwischen der Laufschienen-Rolle und der Stegfläche der Führungsschiene normalerweise bestehenden Zwischenraum in der ganz ausgezogenen Stellung überbrückt.In a further embodiment of the invention, it is expedient if in the region of the web surface of the guide rail which is opposite the fully extended position of the running rail roller, at least one flat elevation which occurs to the roller is provided, that is to say the elevation between the running rail roller and the web surface of the guide rail normally existing space bridged in the fully extended position.

Dabei ist die Ausgestaltung vorzugsweise so getroffen, daß zwei Erhebungen in Form von mit parallelem Abstand zueinander höhenversetzten, aus dem Material des Stegfläche der Führungsschiene vorgeprägten niedrigen Rippenvorsprüngen vorgesehen sind, welche den zwischen der Stegfläche und der zugewandten Flachseite der Laufschienen-Rolle gegebenen Zwischenraum in der ganz ausgezogenen Stellung gerade überbrücken, d.h. an der führungsschienenzugewandten Flachseite der Rolle anliegen.The configuration is preferably such that two elevations are provided in the form of low rib projections which are offset in height with a parallel spacing from one another and are pre-embossed from the material of the web surface of the guide rail and which provide the space between the web surface and the facing flat side of the running rail roller in the bridge the fully extended position, ie rest on the flat side of the roll facing the guide rail.

Die Rippenvorsprünge sind dabei zweckmäßig in solcher Höhenlage angeordnet, daß sie der Rollen-Flachseite mit Abstand ober- bzw. unterhalb der Rollenmittelachse der Laufschienen-Rolle gegenüberstehen. Die Angriffsbereiche der Rippenvorsprünge an der Laufschienen-Rolle beschränken sich also  ―  analog den die Rolle auf der gegenüberliegenden Seite umgreifenden Ränder der Profilschenkel  ―  auf deren Ober- und Unterseite. Ein eventuell vortretender mittlerer Nabenbereich bzw. ein über die Rollen-Flachseite vortretender Lagerzapfen kollidiert also nicht mit den Rippenvorsprüngen.The rib projections are expediently arranged at such a height that they face the flat side of the roller at a distance above or below the central roller axis of the roller track roller. The areas of engagement of the rib projections on the roller track roller are thus limited - analogously to the edges of the profile legs encompassing the roller on the opposite side - on their upper and lower sides. A possibly occurring central hub area or a bearing journal protruding over the flat side of the roller therefore does not collide with the rib projections.

Zusätzlich oder alternativ zu den vorbeschriebenen Ausgestaltungen der Ausziehführung empfiehlt es sich, die lichte Breite des die Führungsschienen-Rolle an der Oberseite umgreifenden Profilschenkels der Laufschiene in dem bei Annäherung an die ganz ausgezogene Stellung von der Führungsschienen-Rolle überfahrenen Endbereich allmählich zu verringern. Damit wird also auch das zwischen dem Profilschenkel der Laufschiene und der Führungsschienen-Rolle normalerweise bestehende Spiel in der ganz ausgezogenen Stellung verringert, was sich in einer entsprechenden Verringerung des Querspiels einer ganz ausgezogenen Schublade auswirkt.In addition or as an alternative to the above-described configurations of the pull-out guide, it is advisable to gradually reduce the clear width of the profile leg of the running rail encompassing the upper side of the guide rail roller in the end region which is overrun by the guide rail roller when the fully extended position is approached. This also reduces the game normally existing between the profile leg of the running rail and the guide rail roller in the fully extended position, which results in a corresponding reduction in the transverse play of a fully extended drawer.

Der angestrebte Effekt kann auch noch dadurch verbessert werden, daß die Laufschiene in dem der Führungsschienen-Rolle in der ganz ausgezogenen Stellung gegenüberstehenden Bereich mit einem von ihrem unteren Randbereich zur zugewandten Flachseite der Führungsschienen-Rolle vortretenden Lappen versehen ist, welcher den zwischen der Laufschiene un der zugewandten Flachseite der Führungsschienen-Rolle bestehenden Zwischenraum gerade überbrückt.The desired effect can also be improved in that the running rail in the area opposite the guide rail roller in the fully extended position is provided with a tab protruding from its lower edge region to the flat side of the guide rail roller facing the un between the running rail the existing flat side of the guide rail roller bridging existing space.

Der Lappen kann dabei aus dem Material der Laufschiene selbst freigestanzt und in die zur Führungsschienen-Rolle vortretende Lage umgebogen sein, oder er ist ein gesondert hergestellter und in der bestimmungsgemäßen Lage an der Laufschiene  ―  beispielsweise durch Punktschweißen, Vernieten od.dgl.  ―  befestigter Teil.The tab can be punched out of the material of the running rail itself and bent into the position facing the guide rail roll, or it is a separately produced and in the intended position on the running rail - for example by spot welding, riveting or the like. - fastened part.

In Figur 1 ist eine in ihrer Gesamtheit mit 10 bezeichnete Ausziehführung im Querschnitt dargestellt, wobei angenommen sei, daß die Ausziehführung 10 zur Führung einer Seitenwand 12 einer Schublade an der zugeordneten Tragwand 14 eines Schranks diene. An der nicht dargestellten gegenüberliegenden Schubladen-Seitenwand und der zugehörigen Schrank-Tragwand ist eine weitere spiegelbildlich angeordnete, jedoch gegenüber der dargestellten Ausziehführung vereinfachte übliche Ausziehführung angeordnet zu denken.In Figure 1, a pull-out guide designated in its entirety with 10 is shown in cross-section, it being assumed that the pull-out guide 10 serves to guide a side wall 12 of a drawer on the associated support wall 14 of a cabinet. On the opposite drawer side wall, not shown, and the associated cupboard support wall, another conventional pull-out guide, which is arranged in mirror image, but is simplified compared to the pull-out guide shown, is to be considered.

Die Ausziehführung 10 weist eine an der Schubladen-Seitenwand 12 befestigbare langgestreckte profilierte Laufschiene 16 (siehe auch Fig. 3 und 5) mit zwei von einer senkrechten Stegfläche 18 in entgegengesetzte Richtungen etwa rechtwinklig abgekanteten Profilschenkeln 20, 22 auf die. Die Befestigtung der Laufschiene 16 an der Schubladen-Seitenwand 12 erfolgt so, daß die Stegfläche 18 an der tragwandzugewandten Seitenfläche und der untere Profilschenkel 22 an der unteren Stirnkante der Schubladen-Seitenwand 12 anliegt, wobei die Laufschiene mit Befestigungsschrauben 24 an der Seitenwand 12 befestigt ist, welche durch Bohrungen im Profilschenkel 22 in die Stirnkante der Schubladen-Seitenwand eingeschraubt sind. An dem in den Figuren 3 und 5 links gelegenen schrankinneren oder rückwärtigen Ende der Laufschiene 16 ist eine auf einem in der Stegfläche 18 vernieteten zur Tragwand vorstehenden Lagerzapfen 26 drehbar gelagerte Rolle 28 angeordnet, deren Umfangsfläche den in diesem Endbereich weggeschnittenen oberen Profilschenkel 20 der Laufschiene 16 noch etwas überragt. Der Profilschenkel 20 ist im übrigen an seinem freien Rand entlang eines schmalen Randstreifens 30 wieder nach unten umgebogen. Die zwischen der Stegfläche 18 und dem umgebogenen Randstreifen 30 liegende untere Fläche des Profilschenkels 20 bildet so die Laufbahn für eine im folgenden noch beschriebene zweite Rolle.The pull-out guide 10 has an elongated profiled running rail 16 (see also FIGS. 3 and 5) which can be fastened to the drawer side wall 12 and has two profile legs 20, 22 which are bent approximately at right angles from a vertical web surface 18 in opposite directions. The running rail 16 is fastened to the drawer side wall 12 in such a way that the web surface 18 rests on the side surface facing the load-bearing wall and the lower profile leg 22 bears against the lower end edge of the drawer side wall 12, the running rail being fastened to the side wall 12 with fastening screws 24 , which are screwed through holes in the profile leg 22 into the front edge of the drawer side wall. 3 and 5 to the left of the cabinet inner or rear end of the running rail 16 there is a rotatably mounted roller 28 on a bearing pin 26 projecting to the supporting wall in the web surface 18, the peripheral surface of which roller 28 cuts the upper profile leg 20 of the running rail 16 cut away in this end region still towering over something. The profile leg 20 is bent back down at its free edge along a narrow edge strip 30. The between the web surface 18 and the bent edge strip 30 lying lower surface of the profile leg 20 thus forms the track for a second role described below.

Die Rolle 28 ihrerseits rollt auf Laufbahnen der Führungsschiene 32 (siehe auch Fig. 2 und 4) ab, welche die Form einer U-förmigen Profilschiene mit zwei in gleicher Richtung etwa rechtwinklig von einer Stegfläche 34 abgekanteten Profilschenkeln 36, 38 hat, deren Stegfläche 34 mit zur Schubladen-Seitenwand 12 weisenden Profilschenkeln 36, 38 auf der Tragwand 14 aufgeschraubt ist. Der Abstand zwischen den einander zugewandten, die Laufbahnen für die Rollen 28 bildenden Innenflächen der Profilschenkel ist dabei etwa gleich bzw. nur geringfügig größer als der Durchmesser der Rolle 28 bemessen. Die Rolle 28 rollt also  ―  je nach Ausziehstellung der Schublade  ―  auf der Innenfläche des unteren bzw. oberen Profilschenkels 36 bzw. 38 ab, wobei auch diese Profilschenkel wieder an ihren freien Rändern entlang jeweils einers schmalen freien Randstreifens 40, 42 nach unten bzw. oben umgebogen sind. Die freien Randstreifen 40, 42 umgreifen also die Laufschienen-Rolle 28 an der Ober- und Unterseite. Am schrankäußeren oder in Ausziehrichtung vorderen Endbereich der Führungsschiene 32 sind die Profilschenkel 36, 38 abgeschnitten und die Stegfläche 34 ist zu einer ebenen Lagerplatte 44 vergrößert, in welcher ein zur Schubladen-Seitenwand 12 vorstehender Lagerzapfen 46 vernietet ist, auf welchem die obenerwähnte zweite Rolle 48 drehbar gelagert ist, auf deren Umfangsfläche die von der Unterseite des Profilschenkels 20 der Laufschiene 16 gebildete Laufbahn abrollt.The roller 28 in turn rolls on raceways of the guide rail 32 (see also FIGS. 2 and 4), which has the shape of a U-shaped profile rail with two profile legs 36, 38 bent in the same direction approximately at right angles from a web surface 34, the web surface 34 with profile legs 36, 38 facing the drawer side wall 12 is screwed onto the supporting wall 14. The distance between the mutually facing inner surfaces of the profile legs forming the raceways for the rollers 28 is approximately the same or only slightly larger than the diameter of the roller 28. The roller 28 rolls - depending on the extended position of the drawer - on the inner surface of the lower or upper profile leg 36 or 38, these profile legs again along their free edges along a narrow free edge strip 40, 42 down or up are bent. The free edge strips 40, 42 thus embrace the roller roller 28 on the top and bottom. The profile legs 36, 38 are cut off at the outside of the cabinet or at the front in the pull-out direction of the guide rail 32 and the web surface 34 is enlarged to form a flat bearing plate 44 in which a bearing pin 46 protruding toward the side wall 12 of the drawer is riveted, on which the second roller 48 mentioned above is riveted is rotatably mounted, on the circumferential surface of the track formed by the underside of the profile leg 20 of the track 16 rolls.

Das in den Figuren 2 und 4 rechts gelegene Ende der Führungsschiene 32 ist durch einen von der Stegfläche 34 nach vorn zwischen die Profilschenkel 36, 38 gekanteten senkrechten Lappen 50 gegen den Austritt der Laufschienen-Rolle 28 verschlossen.The end of the guide rail 32 located on the right in FIGS. 2 and 4 is closed by a vertical tab 50, which is folded forward from the web surface 34 between the profile legs 36, 38, against the exit of the roller roller 28.

In der montierten Ausziehführung läuft also die Umfangsfläche der Laufschienen-Rolle 28 auf den von den einander zugewandten Innenflächen der Profilschenkel 36, 38 gebildeten Laufbahnen der Führungsschiene 32 und die Umfangsfläche der Führungsschienen-Rolle 48 auf der von der nach unten weisenden Fläche des Profilschenkels 20 gebildeten Laufbahn der Laufschiene 16, wobei die umgebogenen schmalen Randstreifen 40, 42 die Rolle 28 an der Ober- und der Unterseite und der umgebogene Randstreifen 30 die Rolle 48 an der Oberseite umgreift, so daß die montierte Führungs- und Laufschiene rechtwinklig zur Ausziehrichtung nur ein gewisses, relativ geringes Spiel aufweisen, dabei jedoch in dieser Querrichtung nicht voneinander trennbar sind.In the assembled pull-out guide, the circumferential surface of the guide rail roller 28 thus runs on the raceways of the guide rail 32 formed by the mutually facing inner surfaces of the profile legs 36, 38, and the circumferential surface of the guide rail roller 48 runs on the downward-facing surface of the profile leg 20 Raceway of the track 16, the bent narrow edge strips 40, 42 around the roller 28 on the top and bottom and the bent edge strip 30 engages around the roller 48 on the top, so that the mounted guide and guide rail perpendicular to the direction of extension only a certain amount , have relatively little play, but are not separable from each other in this transverse direction.

Um das zwischen der Lauf- und der Führungsschiene quer zur Ausziehrichtung herrschende Spiel in der ganz ausgezogenen Stellung zu verringern, ist eine Reihe von Maßnahmen getroffen, die nachstehend beschrieben werden. So ist die zwischen den umgebogenen Randstreifen 40, 42 der Profilschenkel 36, 38 und der Stegfläche 34 der Führungsschiene 32 gemessene lichte Weite in dem  ―  in den Figuren 2 und 4 links gelegenen  ―  Endbereich, in welchen die Laufschienen-Rolle 28 bei Annäherung an die ganz ausgezogene Stellung eintritt, gegenüber der über die restliche Länge der Führungsschiene vorgesehenen normalen lichten Weite verringert, so daß die Profilschenkel in diesem Endbereich ihre Breite in der Draufsicht in der in Fig. 4 erkennbaren Weise verringern. Dadurch wird auch das zwischen der Laufschienen-Rolle 28 und den umgekanteten Randstreifen 40, 42 herrschende Querspiel bei Annäherung an die ganz ausgezogene Endestellung zunehmend verringert.In order to reduce the play between the running rail and the guide rail transverse to the pull-out direction in the fully extended position, a number of measures have been taken, which are described below. Thus, the clear width measured between the bent edge strips 40, 42 of the profile legs 36, 38 and the web surface 34 of the guide rail 32 is in the end region - on the left in FIGS. 2 and 4 - in which the running rail roller 28 approaches the fully extended position occurs, compared to the normal clear width provided over the remaining length of the guide rail, so that the profile legs in this end region reduce their width in the plan view in the manner shown in FIG. 4. As a result, the transverse play prevailing between the running rail roller 28 and the folded edge strips 40, 42 is also increasingly reduced when the fully extended end position is approached.

Ergänzt wird dieser Effekt durch zwei zueinander höhenversetzte parallele Rippenvorsprünge 52, welche im Bereich der ganz ausgezogenen Endstellung der Laufschienen-Rolle 28 aus der Stegfläche 34 der Führungsschiene 32 so weit vorgeprägt sind, daß sie an der zugewandten Flachseite der Rolle 28 zur Anlage kommen.This effect is supplemented by two parallel rib projections 52 which are offset in height from one another and which are so far pre-embossed in the region of the fully extended end position of the roller roller 28 from the web surface 34 of the guide rail 32 are that they come to rest on the facing flat side of the roller 28.

Auch an der Laufschiene 16 sind Maßnahmen getroffen, durch welche das Querspiel in der ganz ausgezogenen Stellung verringert wird. Entsprechend der oben geschilderten Verringerung der lichten Weite der Profilschenkel 36, 38 der Führungsschiene 32 verringert sich auch die Breite des Profilschenkels 20 bzw. seine lichte Weite zwischen der Stegfläche 18 und dem umgebogenen Rand 30 in dem von der Führungsschienen-Rolle 48 bei Annäherung an die ganz ausgezogene Endstellung überfahrene Endbereich allmählich, was in Fig 5 an dem im Bereich des linken Endes schmäler werdenden Profilschenkels 20 erkennbar ist.Measures are also taken on the running rail 16 by means of which the transverse play is reduced in the fully extended position. Corresponding to the above-described reduction in the clear width of the profile legs 36, 38 of the guide rail 32, the width of the profile leg 20 or its clear width between the web surface 18 and the bent edge 30 in that of the guide rail roller 48 when approaching the is reduced fully extended end position gradually passed over the end region, which can be seen in FIG. 5 from the profile leg 20 which becomes narrower in the region of the left end.

Darüber hinaus ist die Laufschiene 16 in dem der Führungsschienen-Rolle 48 in der ganz ausgezogenen Stellung gegenüberstehenden Bereich mit einem vom unteren Randbereich ihrer Stegfläche 18 vortretenden Lappen 54 versehen, welcher den Zwischenraum zwischen der Stegfläche 18 und der dieser zugewandten Flachseite der Führungsschienen-Rolle 48 überbrückt und im unteren Umfangsbereich an der Rolle 48 zur Anlage kommt. Im gezeigten Fall ist der Lappen 54 aus dem Material der Laufschiene 16 selbst freigestanzt und in die zur Führungsschienen-Rolle vortretende Lage umgebogen. Das Material des Lappens 54 stammt aus dem Bereich des in Fig. 5 erkennbaren Ausschnitts 56 im unteren Profilschenkel 22 der Laufschiene 16. Alternativ kann der Lappen natürlich auch von einem gesondert hergestellten und beispielsweise durch Punktschweißung am Profilschenkel 22 befestigten Metallblech-Teil bestehen.In addition, the running rail 16 is provided in the region opposite the guide rail roller 48 in the fully extended position with a tab 54 which protrudes from the lower edge region of its web surface 18 and which defines the space between the web surface 18 and the flat side of the guide rail roller 48 facing it bridged and comes into contact with the roller 48 in the lower peripheral region. In the case shown, the flap 54 is stamped out of the material of the running rail 16 itself and bent into the position that occurs in relation to the guide rail roll. The material of the flap 54 comes from the region of the cutout 56 in the lower profile leg 22 of the running rail 16, which can be seen in FIG. 5. Alternatively, the flap can of course also consist of a separately produced sheet metal part, for example by spot welding on the profile leg 22.
