Description

Die vorliegende Erfindung betrifft einen Rolltürschrank gemäss dem Oberbegriff des Patentanspruches 1.The present invention relates to a roller door cabinet according to the preamble of claim 1.

Schränke mit auf dem Rolladenprinzip basierenden Rolltüren sind in vielfältigen Ausführungen bekannt. Rolltüren benötigen im Unterschied zu Flügeltüren keinen Raum ausserhalb des Schrankes in geöffnetem Zustand. Üblicherweise sind die Rolltüren in geeigneten Nuten in den Seitenwänden oder im Deckel bzw. Bodenteil des Schrankes geführt und schwenken bei Öffnung in den hinteren Teil des Schrankes ein.Cabinets with roller doors based on the roller shutter principle are known in a wide variety of designs. In contrast to double doors, roller doors do not require any space outside the cabinet when it is open. The roller doors are usually guided in suitable grooves in the side walls or in the lid or bottom part of the cabinet and pivot into the rear part of the cabinet when opened.

Aus der DE-U-8808914.2 ist jedoch auch schon ein Rolltürschrank der eingangs genannten Art bekannt geworden, d.h. mit einer Rolltür, welche an ringförmig geschlossenen , über Rollen geführten Bändern aufgehängt ist.From DE-U-8808914.2, however, a roller door cabinet of the type mentioned at the outset has also become known, i.e. with a roller door, which is suspended from closed, hinge-guided hinges.

Weiter ist aus der DE-A-3531675 ein Schrankelement bekannt, bei dem eine aus elastischem Material bestehende Frontbespannung von Nylonfäden gespannt wird, welche in Führungsschienen sowie über Rollen laufen.Furthermore, a cabinet element is known from DE-A-3531675, in which a front covering made of elastic material is stretched by nylon threads which run in guide rails and over rollers.

Gegenstand der vorliegenden Erfindung ist ein Rolltürschrank wie er im Patentanspruch 1 definiert ist.The present invention relates to a roller door cabinet as defined in claim 1.

Vorteilhafte und deshalb auch bevorzugte Ausgestaltungen des erfindungsgemässen Rollschranks sind in den abhängigen Ansprüchen gekennzeichnet.Advantageous and therefore also preferred embodiments of the roller cabinet according to the invention are characterized in the dependent claims.

Weitere Ausgestaltungen sowie auch die Vorteile der vorliegenden Erfindung ergeben sich aus der nachfolgenden Erläuterung von Ausführungsbeispielen.Further refinements and also the advantages of the present invention result from the following explanation of exemplary embodiments.

In den einzelnen Figuren sind übereinstimmende Teile mit übereinstimmenden Bezugszeichen versehen.Corresponding parts in the individual figures are provided with the same reference numerals.

Der Rolltürschrank von Fig. 1 weist einen quadratischen Boden 1 und einen flächengleichen quadratischen Deckel 2 auf, welche jeweils aus zwei Platten 1.1 und 1.2 bzw. 2.1 und 2.2 bestehen. Die beiden Platten sind jeweils mit Abstand voneinander verschraubt. Weiter weist der Rolltürschrank zwei Seitenwände 3 und 4, eine Rückwand 5 sowie Einlagefächer 6 auf. Der Schankkörper in ist sich stabil, insbesondere auch schubfest.1 has a square base 1 and a square cover 2 of the same area, which each consist of two plates 1.1 and 1.2 or 2.1 and 2.2. The two plates are screwed at a distance from each other. Furthermore, the roller door cabinet has two side walls 3 and 4, a rear wall 5 and storage compartments 6. The bar body is stable, in particular also shear-resistant.

An den vier Ecken des Bodens 1 sowie des Deckels 2 sind zwischen den beiden Platten jeweils flache, scheibenförmige Rollen 7 frei drehbar, vorzugsweise mittels Kugellagern, gelagert. Wie dies in Fig. 4 zu erkennen ist, sind die Rollen auf ihrem Umfang mit einer mittig umlaufenden Nut 7.1 versehen. Kugellager zur reibungsarmen Lagerung der Rollen 7 sind in Fig. 4 mit 7.2 bezeichnet. Die Rollen 7 weisen vorzugsweise einen Radius von etwa 40 mm auf. Über die Rollen 7 ist am Boden 1 sowie am Deckel 2 jeweils ein ringförmig in sich geschlossenes Band 8 geführt. Das Band 8 ist vorzugsweise ein etwa 2/10 mm dickes, etwa 30 mm breites Federstahlband. Zum Spannen der Bänder 8 ist sowohl am Boden 1 als auch am Deckel 2 jeweils eine der Rollen 7 bezüglich ihrer Position in der Ringebene des jeweiligen Bandes radial verstellbar. Den Mechanismus hierzu zeigt Fig. 7. Die Rolle 7 ist hier in einem im Profil u-förmigen Haltebügel 7.3 gehalten, welcher an einen Gewindebolzen 7.4 angeschraubt ist. Der Gewindebolzen 7.4 steckt in einer Haltebüchse 7.5, die fest mit den Platten 1.1 und 1.2 verbunden ist. Auf den Gewindebolzen aufgeschraubt ist eine Sechskantmutter 7.7, die sich gegen eine Feder 7.8 in der Haltebüchse 7.5 abstützt. Das Spannen erfolgt mittels einer Spannschraube 7.6. Der Sechskantkopf der Spannschraube 7.6 sowie die Sechskantmutter 7.7 auf dem Gewindebolzen 7.4 sind über geeignete Öffnungen 7.9 in der Platte 1.1 zugänglich.At the four corners of the bottom 1 and the cover 2, flat, disk-shaped rollers 7 are each freely rotatable between the two plates, preferably by means of ball bearings. As can be seen in FIG. 4, the rollers are provided with a circumferential groove 7.1 on their circumference. Ball bearings for low-friction mounting of the rollers 7 are denoted by 7.2 in FIG. 4. The rollers 7 preferably have a radius of approximately 40 mm. There is a ring in each case at the bottom 1 and at the cover 2 via the rollers 7 closed band 8 out. The band 8 is preferably an approximately 2/10 mm thick, approximately 30 mm wide spring steel band. For tensioning the straps 8, one of the rollers 7 is radially adjustable with respect to its position in the ring plane of the respective strap both on the bottom 1 and on the cover 2. The mechanism for this is shown in FIG. 7. The roller 7 is held here in a U-shaped bracket 7.3 which is screwed to a threaded bolt 7.4. The threaded bolt 7.4 is in a holding sleeve 7.5, which is firmly connected to the plates 1.1 and 1.2. A hexagon nut 7.7, which is supported against a spring 7.8 in the holding sleeve 7.5, is screwed onto the threaded bolt. Tensioning is carried out using a tension screw 7.6. The hexagon head of the clamping screw 7.6 and the hexagon nut 7.7 on the threaded bolt 7.4 are accessible via suitable openings 7.9 in the plate 1.1.

Der Rolltürschrank von Fig. 1 ist weiter mit einer nur teilweise sowie verkürzt dargestellten Rolltür 9 versehen, welche an den Bändern 8 oben und unten befestigt ist und gemeinsam mit diesen um den ganzen Schrankkörper umlaufen kann. Die Rolltür 9 überdeckt natürlich nur einen Teil des Umfanges des Schrankkörpers und gibt in einer geeigneten Stellung seine vordere Öffnung frei.The roller door cabinet of Fig. 1 is further provided with a roller door 9 shown only partially and shortened, which is attached to the hinges 8 above and below and can rotate together with these around the entire cabinet body. The roller door 9 naturally covers only part of the circumference of the cabinet body and, in a suitable position, releases its front opening.

Die Rolltür besteht aus einer Vielzahl von Lamellen 9.1 bzw. 9.2, welche an ihren Längsseiten über Gelenkverbindungen 9.3 bzw. 9.4 drehbeweglich miteinander verbunden sind. Die Länge der Lamellen entspricht der Höhe des Schrankkörpers.The roller door consists of a plurality of slats 9.1 and 9.2, which are connected to one another on their long sides via articulated connections 9.3 and 9.4. The length of the slats corresponds to the height of the cabinet body.

Bei jeder Gelenkverbindung 9.3 ist ein Verbindungsprofil 9.5 vorgesehen, an dem die jeweils angrenzenden Lamellen mit ihren jeweils angrenzenden Längskanten drehbeweglich angelenkt sind. An den Längskanten der Lamellen 9.1 und 9.2 dazu jeweils vorgesehene Greifrillen 9.1.1 bzw. 9.2.1 umgreifen jeweils an den Verbindungsprofilen 9.5 vorgesehene Rundstege 9.5.1.In each articulated connection 9.3, a connection profile 9.5 is provided, on which the respectively adjacent slats are pivotally articulated with their respectively adjacent longitudinal edges. Gripping grooves 9.1.1 and 9.2.1 respectively provided on the longitudinal edges of the slats 9.1 and 9.2 encompass round webs 9.5.1 provided on the connecting profiles 9.5.

Bei den übrigen Gelenkverbindungen 9.4 sind jeweils Zwischenprofile 9.8 vorgesehen, die eine unmittelbare reibende Berührung der angrenzenden Lamellen aneinander verhindern. Die Zwischenprofile 9.8 sind in Greifrillen 9.1.2 an der Längskante der Lamellen 9.1 eingeschoben. Die im Profil hakenförmig abgebogene Längskante der anderen Lamellen 9.2 ist in eine geeignete Rille im Zwischenprofil 9.8 formschlüssig eingeschoben.In the other articulated connections 9.4, intermediate profiles 9.8 are provided in each case, which prevent the abutting slats from coming into direct contact with one another. The intermediate profiles 9.8 are inserted in gripping grooves 9.1.2 on the longitudinal edge of the slats 9.1. The longitudinal edge of the other slats 9.2, which is bent like a hook, is positively inserted into a suitable groove in the intermediate profile 9.8.

Die Verbindungsprofile 9.5 sind an in regelmässigen Abständen vorgesehenen Befestigungspunkten 8.1 an den Bändern 8 befestigt. Die Befestigung erfolgt mittels einer Schnappverbindung, auf die nachstehend noch eingegangen wird. Die jeweils anderen Gelenkverbindungen 9.4 sind dagegen frei.The connecting profiles 9.5 are fastened to the bands 8 at fastening points 8.1 provided at regular intervals. The attachment is made by means of a snap connection, which will be discussed below. The other joint connections 9.4 are free.

Der Abstand A zwischen den Befestigungspunkten 8.1 ist kleiner gewählt als die Summe der Breite zweier Lamellen. Der Abstand A beträgt vorzugsweise 35 mm. Weiter sind die Lamellen im Profil kreisförmig gebogen. Jeweils zwei Lamellen bilden zwischen zwei benachbarten, freien, jeweils nicht mit den Befestigungspunkten 8.1 verbundenen Gelenkverbindungen 9.4 auf den Abschnitten zwischen den Rollen 7 im Profil eine etwa halbkreisförmige, rinnenartige Vertiefung, wie dies in Fig. 3 gut zu erkennen ist. Im Krümmungsbereich an den Rollen 7 sind diese Vertiefungen etwas erweitert, was anhand von Fig. 3 ebenfalls deutlich zu sehen ist. Die Profilausformung der Lamellen dient einerseits zur Versteifung der Rollentür, zum anderen sind die sich ergebenden Längsstege entlang der freien Gelenkverbindungen 9.4 auch als Handgriffe zum Verschieben der Rolltür geeignet.The distance A between the attachment points 8.1 is chosen smaller than the sum of the width of two slats. The distance A is preferably 35 mm. The slats are also circularly curved in profile. Two slats each form an approximately semicircular, channel-like depression between two adjacent, free, articulated connections 9.4, each not connected to the attachment points 8.1, on the sections between the rollers 7, as can be seen clearly in FIG. 3. In the region of curvature on the rollers 7, these depressions are somewhat widened, which can also be seen clearly from FIG. 3. The profile formation of the slats serves on the one hand to stiffen the roller door, and on the other hand the resulting longitudinal webs along the free articulated connections 9.4 are also suitable as handles for moving the roller door.

Wie anhand von Fig. 5 zu erkennen ist, sind die Bänder 8 im Abstand A der Befestigungspunkte 8.1 für die Gelenkverbindungen 9.3 mit Löchern versehen. In diese Löcher sind jeweils innenseitig über die Bänder überstehende Rahmenelemente 10 eingesetzt. Die Rahmenelemente 10 sind aus Kunststoff und im Spritzgussverfahren an den Rand der Löcher in den Bändern angeformt. An den Rollen 7 greifen die innenseitig über die Bänder 8 überstehenden Teile 10.1 der Rahmenelemente 10 jeweils in die Umfangsnut 7.1 der Rollen 7 ein. Bei der genannten Bemessung des Abstandes A im Verhältnis zum Radius der Rollen ist sichergestellt, dass an jeder Rolle 7 jeweils mindestens ein Rahmenelement 10 in die Umfangsnut 7.1 eingreift. Die Bänder 8 werden dadurch auf den Rollen 7 zentriert und am Abgleiten von diesen gehindert.As can be seen from FIG. 5, the strips 8 are provided with holes at a distance A from the attachment points 8.1 for the articulated connections 9.3. Frame elements 10 projecting from the inside of the strips are inserted into these holes. The frame elements 10 are made of plastic and injection molded onto the edge of the holes in the strips. On the rollers 7, the parts 10.1 of the frame elements 10 projecting on the inside beyond the bands 8 each engage in the circumferential groove 7.1 of the rollers 7. Given the dimensioning of the distance A in relation to the radius of the rollers, it is ensured that at least one frame element 10 engages in the circumferential groove 7.1 on each roller 7. The belts 8 are thereby centered on the rollers 7 and prevented from sliding off them.

Ein weiterer Zentrierungseffekt ergibt sich durch eine leicht konvexe Ausbildung der Umfangsfläche der Rollen, wobei diese von der mittigen Nut nach aussen um etwa um 2° geneigt zurücktritt.A further centering effect results from a slightly convex design of the circumferential surface of the rollers, which recedes outward from the central groove by approximately 2 °.

Auf das obere und das untere Ende der Verbindungsprofile 9.5 sind jeweils Abschlussstücke 9.6 in der aus den Figuren erkennbaren Weise aufgesteckt (schwalbenschwanzartige Verbindung). Diese arretieren einerseits die angrenzenden Lamellen bezüglich ihrer Längsverschieblichkeit gegeneinander sowie gegenüber dem Verbindungsprofil, welche sich aus der Art der Gelenkverbindung ergibt. Die Abschlussstücke 9.6 sind andererseits mit angeformten, federnden Schnappnasen 9.6.1 zum Einschnappen in die Öffnungen der Rahmenelemente 10 an den Befestigungspunkten 8.1 der Bänder 8 versehen.End pieces 9.6 are each attached to the upper and lower ends of the connecting profiles 9.5 in the manner recognizable from the figures (dovetail-like connection). On the one hand, these lock the adjacent slats with respect to their longitudinal displaceability with respect to one another and with respect to the connecting profile, which results from the type of articulated connection. On the other hand, the end pieces 9.6 are provided with molded, resilient snap lugs 9.6.1 for snapping into the openings of the frame elements 10 at the fastening points 8.1 of the straps 8.

Die Lamellen 9.1 bzw. 9.2 sind vorzugsweise aus einem Metall wie z.B. Aluminium, die Verbindundsprofile 9.5 dagegen aus einem Kunststoff mit gegenüber Metall reibungsarmen Eigenschaften. Auch die Zwischenprofile 9.8 der freien Gelenkverbindungen 9.4 sowie die Abschlussstücke 9.6 sind vorzugsweise aus einem solchen Kunsstoffmaterial hergestellt. Bei einer solchen Ausbildung weist die Rolltür 9 selbst bei einer Höhe von bis zu 2 m eine ausreichende Stabilität auf und ist leichtgängig sowie praktisch geräuschlos verschiebbar. Zur Geräuschdämpfung trägt im Übrigen auch das freie Aufstehen der Lamellen auf den unteren Abschlussstücken 9.6 bei.The lamellae 9.1 and 9.2 are preferably made of a metal such as aluminum, while the connecting profiles 9.5 are made of a plastic with low-friction properties compared to metal. Also the intermediate profiles 9.8 of the free articulated connections 9.4 and the end pieces 9.6 are preferably made of such a plastic material. With such a design, the roller door 9 has sufficient stability even at a height of up to 2 m and can be moved easily and practically silently. Incidentally, the free standing of the slats on the lower end pieces 9.6 also contributes to noise reduction.

Zwischen zwei Rollen 7 kann bei langen Abständen, wie sie sich z.B. bei einer doppelten Schrankbreite ergeben, zur Vermeidung eines Durchhängens der Rolltür zwischen den Rollen unter dem unteren Band noch ein Unterstützungselement 11, beispielsweise an der unteren Platte 1.1 des Bodens 1, montiert sein, wie es in Fig. 8 dargestellt ist. Das Unterstützungselement weist mehrere Rollen 11.1 sowie eine Scheibe 1.2 in Reihe auf. Die Abstände der Rollen bzw. der Scheibe sowie ihre Abmessungen sind derart gewählt, dass jeweils mindestens eines der genannten Abschlussstücke 9.6 auf einer der Rollen 11.1 aufsteht und die genannte Scheibe 11.2 in einen Zwischenraum zwischen dem unteren Band 8 und einem anderen Abschlussstück 9.6 eingreift. Ein Unterstützungselement der beschriebenen Art ist in der Regel jedoch nur erforderlich, sofern die Schrankbreite etwa einen Meter übersteigt.In the case of long distances, as can be seen e.g. in the case of a double cabinet width, in order to avoid sagging of the roller door between the rollers under the lower hinge, a support element 11, for example on the lower plate 1.1 of the base 1, can be mounted, as shown in FIG. The support element has a plurality of rollers 11.1 and a disk 1.2 in series. The distances between the rollers or the disk and their dimensions are selected such that at least one of the end pieces 9.6 mentioned stands on one of the rollers 11.1 and the said disk 11.2 engages in an intermediate space between the lower band 8 and another end piece 9.6. However, a support element of the type described is usually only required if the cabinet width exceeds about one meter.

Im Rahmen der vorliegenden Erfindung lassen sich in einfacher Weise auch Rollschränke mit nicht rechteckigen Grundrissen realisieren. Beispiele hierfür zeigt Fig. 11 unter a) bis f). Fig. 11 a) zeigt einen dreieckigen Grundriss und Fig. 11 b) einen sechseckigen, wobei die Durchmesser der einzelnen, in den Ecken angeordneten Rollen jeweils gleich sind. Bei den unter c) bis f) dargestellten Ausführungsformen sind Rollen mit verschiedenen Durchmessern verwendet. Inbesondere entspricht der Durchmesser der grossen Rollen von Fig. 11 c) und Fig. 11 f) der jeweiligen Schranktiefe, wodurch sich abgerundete Schrankseiten ergeben.Within the scope of the present invention, roller cabinets with non-rectangular floor plans can also be easily realized. 11 shows examples of this under a) to f). FIG. 11 a) shows a triangular plan and FIG. 11 b) a hexagonal one, the diameters of the individual rolls arranged in the corners being the same in each case. Rollers with different diameters are used in the embodiments shown under c) to f). In particular, the diameter of the large rollers of FIGS. 11 c) and 11 f) corresponds to the respective cabinet depth, which results in rounded cabinet sides.
