Description

Gegenstand der vorliegenden Erfindung ist eine Rollenauszugsvorrichtung für Schubladen gemäss Oberbegriff des Patentanspruches 1.The present invention relates to a roller pull-out device for drawers according to the preamble of patent claim 1.

Rollenauszugsvorrichtungen sind bekannt. Diese bestehen, soll ein Vollauszug möglich sein, aus drei Teilen, nämlich einem Korpusteil, einem Schubladenteil sowie einem den Korpusteil mit dem Schubladenteil verbindenden Läuferteil. Bei modernen Rollenauszugsvorrichtungen sind am Läuferteil Stützrollen angeordnet, welche ein widerstandsarmes Ausziehen der Schublade ermöglichen und die durch das Gewicht der Schublade auf der Auszugsvorrichtung lastende Druckkräfte aufnehmen. Die seitlichen Kräfte, welche durch unsymmetrisches Einleiten der Auszugskräfte entstehen, werden in den meisten Fällen durch die seitlichen Flanken der Stützrollen oder durch Kunststoffgleitprofile übernommen. Es ist auch bekannt, am Läuferteil eine oder mehrere Führungsrollen mit vertikaler Drehachse anzuordnen.
Eine solche Rollenauszugsvorrichtung ist aus der US-PS 2,869,961 bekannt. Die beiden Führungsrollen mit vertikaler Drehachse durchdringen den vertikal liegenden Steg des Läuferteiles und gelangen auf der Aussenseite in Anlage mit dem Korpusteil, sobald der Läuferteil in den Korpusteil einläuft, damit beim Einschieben der Schublade der Läuferteil nicht in Reibkontakt mit dem feststehenden Korpusteil gelangen kann, sondern auf dem Korpusteil abrollen kann. Eine exakte seitliche Führung der Schublade durch diese Rollen könnte nur erfolgen, wenn der Schubladenausschnitt im Schrank von höchster Präzision wäre, was in der Praxis nicht möglich ist. Insbesondere entfällt die seitliche Führung durch die Rollen mit den vertikalen Drehachsen, sobald der vordere Teil des Läuferteiles aus dem Korpus herausbewegt wird. Eine seitliche Führung liegt folglich nur gerade dann bedingt vor, wenn die Schublade ganz eingeschoben ist.
Eine einwandfreie Seitenführung ist aber speziell bei ausgezogener Schublade erwünscht. Dies lässt sich mit der bekannten Ausführung nicht erreichen.
Bei Verwendung der Rollenauszugsvorrichtung für Hängemappen-Registraturauszüge, bei denen beispielsweise zwei oder drei Mappenreihen nebeneinander in einem Rahmen angeordnet sind und die Tiefe des Korpus im Verhältnis zur Breite sehr gering ist, können die bekannten Auszüge nicht befriedigen. Es wurde schon versucht, durch Einsetzen von Scherenmechanismen den Rahmen daran zu hindern, ungleichförmig ausgezogen zu werden und dadurch ein Verklemmen der Auszugsvorrichtung zu verhindern.Roller pull-out devices are known. If full extension is to be possible, these should consist of three parts, namely a carcass part, a drawer part and a slider part connecting the carcass part to the drawer part. In modern roller pull-out devices, support rollers are arranged on the runner part, which enable the drawer to be pulled out with little resistance and absorb the compressive forces exerted on the pull-out device by the weight of the drawer. The lateral forces that arise due to asymmetrical introduction of the pull-out forces are in most cases taken over by the side flanks of the support rollers or by plastic sliding profiles. It is also known to arrange one or more guide rollers with a vertical axis of rotation on the rotor part.
Such a roller pull-out device is known from US Pat. No. 2,869,961. The two guide rollers with a vertical axis of rotation penetrate the vertical web of the runner part and come into contact with the body part on the outside as soon as the runner part runs into the body part, so that when the drawer is pushed in, the runner part cannot come into frictional contact with the fixed body part, but instead can roll on the body part. Exact lateral guidance of the drawer by these rollers could only be achieved if the drawer cutout in the cabinet were of the highest precision, which is not possible in practice. In particular, there is no lateral guidance by the rollers with the vertical axes of rotation as soon as the front part of the rotor part is moved out of the body. Lateral guidance is therefore only conditionally available when the drawer is fully inserted.
Correct lateral guidance is especially desirable when the drawer is pulled out. This cannot be achieved with the known design.
When using the roll pull-out device for suspension file file pull-outs, in which, for example, two or three file rows are arranged next to one another in a frame and the depth of the body is very small in relation to the width, the known pull-outs cannot be satisfactory. Attempts have already been made to use scissor mechanisms to prevent the frame from being pulled out unevenly and thereby preventing the pull-out device from jamming.

Die Erfindung hat sich zur Aufgabe gemacht, eine Rollenauszugsvorrichtung zu schaffen, welche es erlaubt, unter allen Bedingungen - in jeder möglichen Auszugslage - die Schublade leicht ausziehen oder einschieben zu können.
Gelöst wird diese Aufgabe durch eine Rollenauszugsvorrichtung mit den Merkmalen des Patentanspruches 1.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen definiert.
Es gelingt mit der erfindungsgemässen Rollenauszugsvorrichtung, diese unempfindlich gegen Schrägzug zu gestalten, und zwar in jeder beliebigen Auszugsstellung zwischen "voll" ausgezogen und vollständig eingeschoben. Damit ergeben sich keine Probleme beim Ausziehen der Schublade, auch wenn diese entweder einseitig beladen oder die Krafteinleitung zum Ausziehen asymmetrisch erfolgt. Durch die Anordnung einer weiteren Stützrolle kann die Schublade ohne Probleme über die Korpus- bzw. Schrankfront hinaus herausgezogen werden. Die zuhinterst angeordneten Gegenstände, z.B. die Hängemappen in der Schublade bzw. im Auszugrahmen, sind dann leicht zugänglich. Dabei ist die Führung sowohl in horizontaler als auch in vertikaler Richtung stets einwandfrei und auf der gesamten Auszugslänge gewährleistet. Die versetzt übereinander angeordneten Stützrollen erlauben ein sanftes und ruckfreies Einschieben der Schubladen.The invention has set itself the task of providing a roller pull-out device which allows the drawer to be easily pulled out or pushed in under all conditions - in any possible pull-out position.
This object is achieved by a roller pull-out device with the features of patent claim 1.
Further advantageous embodiments of the invention are defined in the dependent claims.
With the roller pull-out device according to the invention, it is possible to make it insensitive to inclined pull, in any pull-out position between "fully" pulled out and fully pushed in. This means that there are no problems when pulling out the drawer, even if it is either loaded on one side or the force is applied asymmetrically to pull it out. By arranging another support roller, the drawer can be pulled out beyond the front of the cabinet or cabinet without any problems. The items at the back, such as the hanging files in the drawer or pull-out frame, are then easily accessible. The guidance in both the horizontal and vertical directions is always flawless and guaranteed over the entire extension length. The staggered support rollers allow the drawers to be inserted smoothly and smoothly.

Der Beistellschrank 1 in Figur 1 besteht im wesentlichen aus einem rechteckigen, vorne offenen Kasten oder Korpus 3, an dessen Seitenwänden 5 Rollenauszugsschienen 7 befestigt sind. Im dargestellten Beispiel sind zwei rechteckige Hängeregistraturrahmen 9, bestehend aus zwei seitlichen Rahmenplatten 11 und zwei quer zur Auszugsrichtung verlaufenden Rahmenstreben 13, ausziehbar eingesetzt. Der obere dargestellte Rahmen 9 ist vollständig ausgezogen; der untere vollständig eingeschoben. Im Rahmen 9 sind zwei Zwischenstege 15 eingesetzt, welche der Auflage der innen liegenden Haken 17 von Hängemäppchen 19 dienen.
Zwischen den oben und unten angeordneten Hängeregistaturrahmen 9 kann ein Zwischenboden 21 eingesetzt sein.
Die Rollenauszugsvorrichtung besteht aus den drei Hauptteilen, nämlich einem Korpusteil 23, einem Schubladenteil 25, welcher gleichzeitig die seitliche Rahmenplatte 11 eines Hängeregistraturrahmens 9 bilden kann, sowie einem Läuferteil 27, der den Korpusteil 23 mit dem Schubladenteil 25 verbindet.
Anhand des in Figur 3 vergrössert dargestellten Läuferteiles 27 wird dessen Aufbau näher erläutert. Der Läuferteil 27 besteht aus einem durch eine Stanz- und Biege- oder Walzoperation erzeugten Läuferblech 29, dessen Unterkante 31 und Oberkante 33 rechtwinklig abgebogen sind. Am hinteren oberen Ende ist eine erste Stützrolle 35 derart befestigt, dass deren Scheitel S die Oberkante 33 überragt. Punktsymmetrisch dazu ist am vorderen unteren Ende die zweite Stützrolle 37 befestigt, deren untenliegender Scheitel die Unterkante 31 überragt. Im zentralen Abschnitt sind vertikal übereinanderliegend oder um einen geringen Abstand versetzt eine dritte Stützrolle 39 und darunter eine vierte Stützrolle 41 am Läuferblech 29 befestigt. Zwischen der ersten und der vierten Stützrolle ist, ebenfalls im Bereich der Unterkante 31, eine fünfte Stützrolle 43 und zwischen der zweiten und dritten Stützrolle oben eine sechste Stützrolle 45 befestigt. Die Drehachsen der Stützrollen 35, 39 und 45 bzw. die Drehachsen der Stützrollen 37, 41 und 43 liegen je in einer gemeinsamen, rechtwinklig zum Läuferblech 29 verlaufenden, horizontal liegenden Ebene.
Unterhalb der sechsten Stützrolle 45 ist an der umgelegten Unterkante 31 eine Abstützung 47 befestigt. Die Abstutzung 47 ist vorzugsweise aus Kunststoff hergestellt und an einer Öffnung in der Unterkante 31 eingerastet. Sie kann rampenförmig ausgebildet sein, und deren Scheitel X liegt seitlich verschoben zu einer durch die Drehachse der Stützrolle 45 gelegten vertikalen Ebene. Anstelle der Abstützung 47 kann auch eine siebte Stützrolle vorgesehen werden. Am hinteren Ende des Läuferbleches 29 ist am horizontal verlaufenden Steg der Unterkante 31 eine erste Führungsrolle 49 mit vertikaler Drehachse befestigt. Der Mantel der ersten Führungsrolle 49 überragt die aussenliegende Oberfläche des Läuferbleches 29. Eine analog ausgebildete und angeordnete zweite Führungsrolle 51 ist zwischen den Stützrollen 43 und 41 an der Unterkante 31 befestigt. Die Führungsrolle 51 liegt vorzugsweise sehr nahe bei der Stützrolle 41.
Anhand der perspektivischen Darstellung in Figur 4 wird die Funktionsweise der dreiteiligen Auszugsvorrichtung näher erläutert. Der Korpusteil 23 besteht aus einem Korpusblech 53, dessen Längskanten zweifach jeweils um einen Winkel von 90° umgelegt sind und eine obere Führungsbahn 55 und eine untere, durch die seitlich nach oben gebogene Kante 56 U-förmige Führungsbahn 57 für die Stützrollen 35 bzw. 41 und 43 bilden. Eine an der unteren Führungsbahn 57 ausgestanzte, nach unten und hinten weglaufende Rampe 59 dient dazu, bei eingeschobenem Hängeregistraturrahmen 9 bzw. einer Schublade diese in eingeschobener Stellung zu halten, indem die Führungsrolle 43 auf der Rampe 59 infolge des Gewichtes des Rahmens 9 nach unten rollt. Analog dazu dient eine nach vorne auf der oberen Führungsbahn 55 in diese hineinragende Rückhalterampe 61 dazu, den Läuferteil 27 daran zu hindern, den Korpusteil 13 zu verlassen. Bei vollständig ausgezogener Schublade tragen die beiden Stützrollen 41 und 37, welche in der unteren Führung 57 rollen, das Gewicht der Schublade. Die Rolle 37 ist nur anfänglich auf der Führung 57 abgestützt; sie trägt aber dauernd an einer Führung 63 die Last der Schublade. Die Stützrollen 35 und 45 verhindern ein nach vorne Kippen und stützen die Schublade an der oberen Führungsbahn 55 bzw. an der Oberkante 33 ab.The side cabinet 1 in FIG. 1 essentially consists of a rectangular box or body 3 open at the front, on the side walls of which 5 roller pull-out rails 7 are fastened. In the example shown, two rectangular suspension file frames 9, consisting of two side frame plates 11 and two frame struts 13 extending transversely to the pull-out direction, are inserted so that they can be pulled out. The upper frame 9 shown is fully extended; the lower one fully inserted. In the frame 9, two intermediate webs 15 are used, which serve to support the inner hooks 17 of hanging cases 19.
An intermediate floor 21 can be inserted between the hanging table frame 9 arranged above and below.
The roller pull-out device consists of the three main parts, namely a body part 23, a drawer part 25, which can simultaneously form the side frame plate 11 of a hanging file frame 9, and a runner part 27, which connects the body part 23 to the drawer part 25.
The structure of the rotor part 27, shown enlarged in FIG. 3, is explained in more detail. The rotor part 27 consists of a rotor plate 29 produced by a punching and bending or rolling operation, the lower edge 31 and upper edge 33 of which are bent at right angles. At the rear upper end, a first support roller 35 is attached in such a way that whose apex S projects above the upper edge 33. Point-symmetrically to this, the second support roller 37 is attached to the lower front end, the apex of which lies below the lower edge 31. In the central section, a third support roller 39 and a fourth support roller 41 are attached to the rotor plate 29 vertically one above the other or offset by a small distance. A fifth support roller 43 is fastened between the first and the fourth support roller, likewise in the area of the lower edge 31, and a sixth support roller 45 is fastened at the top between the second and third support rollers. The axes of rotation of the support rollers 35, 39 and 45 or the axes of rotation of the support rollers 37, 41 and 43 each lie in a common, horizontal plane running at right angles to the rotor plate 29.
A support 47 is fastened to the folded lower edge 31 below the sixth support roller 45. The support 47 is preferably made of plastic and snapped into an opening in the lower edge 31. It can be ramp-shaped, and its apex X is laterally displaced to a vertical plane through the axis of rotation of the support roller 45. Instead of the support 47, a seventh support roller can also be provided. At the rear end of the rotor plate 29, a first guide roller 49 with a vertical axis of rotation is fastened to the horizontally extending web of the lower edge 31. The jacket of the first guide roller 49 projects beyond the outer surface of the rotor plate 29. A second guide roller 51 of similar design and arrangement is fastened between the support rollers 43 and 41 on the lower edge 31. The guide roller 51 is preferably very close to the support roller 41.
The mode of operation of the three-part pull-out device is explained in more detail using the perspective illustration in FIG. The carcass part 23 consists of a carcass plate 53, the longitudinal edges of which are folded twice by an angle of 90 ° each, and an upper guideway 55 and a lower guideway 57 for the support rollers 35 and 41, which is U-shaped by the laterally curved edge 56 and form 43. A punched out on the lower guideway 57, down and back away ramp 59 is used to hold it in the inserted position when the suspension file frame 9 or a drawer is pushed in, by the guide roller 43 rolling down the ramp 59 due to the weight of the frame 9. Analogously, a retaining ramp 61 protruding forward on the upper guide track 55 serves to prevent the rotor part 27 from leaving the body part 13. When the drawer is fully extended, the two support rollers 41 and 37, which roll in the lower guide 57, bear the weight of the drawer. The roller 37 is initially supported on the guide 57; but it constantly carries the load of the drawer on a guide 63. The support rollers 35 and 45 prevent tilting forward and support the drawer on the upper guideway 55 and on the upper edge 33, respectively.

Der Schubladenteil 25, welcher je nach Verwendung der Auszugsvorrichtung 7 als seitliche Rahmenplatte 11 des Hängeregistraturrahmens 9 ausgebildet ist, weist seitlich die U-förmige Führungsschiene 63 auf, deren Schenkel nach unten gerichtet sind. Die von der Führungsschiene 63 gebildete Führungsfläche 65 liegt bei vollständig ausgezogener Auszugsvorrichtung 9 bzw. Schublade mit der unteren Führungsfläche 65 auf der Stützrolle 37 und mit der oben liegenden Führungsfläche 67 von unten an der Stützrolle 45 an.The drawer part 25, which, depending on the use of the pull-out device 7, is designed as a side frame plate 11 of the suspension file frame 9, has the U-shaped guide rail 63 on the side, the legs of which are directed downward. When the pull-out device 9 or drawer is fully extended, the guide surface 65 formed by the guide rail 63 bears against the support roller 37 with the lower guide surface 65 and against the support roller 45 from below with the guide surface 67 located above.

Um ein unbeabsichtigtes Anheben des Hängeregistraturrahmens 9 bzw. der Schublade und damit ein Aushängen des Schubladenteils 25 aus dem Läuferteil 27 zu verhindern, liegt unterhalb der Stützrolle 45 die rampenförmig ausgebildete Abstützung 47. Ein Anschlagnocken 71 an der Unterkante des Läuferteiles 27 verhindert, dass der Schubladenteil 25 über die in Figur 4 gezeigte Stellung hinaus nach rechts verschoben werden kann. Beim Einschieben der Schublade gleitet die Führungsschiene 65, oben und unten an den Stützrollen 41 und 39 anliegend, zwischen den letztgenannten Stützrollen und liegt vollständig eingeschoben zudem mit der Führungsfläche 65 auf dem Scheitel der Stützrolle 43 auf.In order to prevent the suspension file frame 9 or the drawer from being inadvertently lifted and thus the drawer part 25 from hanging out of the runner part 27, the ramp-shaped support 47 lies below the support roller 45. A stop cam 71 on the lower edge of the runner part 27 prevents the drawer part 25 can be shifted to the right beyond the position shown in FIG. When the drawer is pushed in, the guide rail 65 slides between the latter support rollers, abutting the support rollers 41 and 39 at the top and bottom, and also lies fully inserted with the guide surface 65 on the apex of the support roller 43.

Die Führungsrollen 49 und 51 liegen in allen Stellungen der Auszugsvorrichtung, d.h. vollständig zusammengeschoben, vollständig ausgezogen oder in Zwischenstellungen stets mit geringem Spiel seitlich geführt in der U-förmig ausgebildeten unteren Führungsbahn 57 des Korpusteiles 23. Quer zur Verschieberichtung der Auszugsvorrichtung auf diese wirkende Kräfte werden von den beiden Führungsrollen 51 und 49 aufgenommen. Die oben liegende Führungsfläche 63, bzw. der die Führungsfläche 67 bildende horizontale Schenkel, ist am hinteren Ende sowohl oben als auch unten angeschrägt und damit keilförmig ausgebildet. Dies ermöglicht ein sanftes, ruckfreies Einfahren der Führungsflächen 65 und 67 des Schubladenteiles 25 zwischen die beiden Stützrollen 39 und 41.The guide rollers 49 and 51 are in all positions of the pull-out device, i.e. completely pushed together, fully extended or in intermediate positions always with little play laterally guided in the U-shaped lower guide track 57 of the carcass part 23. The upper guide surface 63, or the horizontal leg forming the guide surface 67, is chamfered at the rear end both above and below and is thus wedge-shaped. This enables smooth, jerk-free insertion of the guide surfaces 65 and 67 of the drawer part 25 between the two support rollers 39 and 41.
