Description

Die Erfindung betrifft eine Schließanlage für Schubladenschränke mit mehreren Schubladen. An großen Schubladenschränken, beispielsweise an Kommoden oder Aktenschränken, kann der Schwerpunkt des Schrankes bei mehreren gleichzeitig geöffneten Schubladen nach außerhalb der Standfläche verlagert werden, was ein Umfallen des Schrankes zur Folge hat. Daher darf ein Öffnen zweier Schubladen nacheinander oder gleichzeitig nicht möglich sein.The invention relates to a locking system for drawer cabinets with several drawers. On large drawer cabinets, for example on chests of drawers or filing cabinets, the center of gravity of the cabinet can be shifted outside the stand area if several drawers are open at the same time, which results in the cabinet falling over. It should therefore not be possible to open two drawers one after the other or simultaneously.

Es ist bereits eine Konstruktion bekannt, bei welcher ein gleichzeitiges Ausziehen mehrerer Schubladen und bei einer offenen Schublade das Öffnen weiterer Schubladen verhindert wird. Hierbei sind an den Schubladen Kurvenstücke angebracht und der Schrank ist mit neben den Schubladen angeordneten, senkrecht verschiebbaren Schließstangen mit hervorstehenden Zapfen versehen, wobei eine Haltevorrichtung zum Halten der Schließstange in ihrer verschobenen Stellung vorgesehen ist. Den Kurvenstücken sind außerdem mit den Zapfen zusammenwirkende Stopper zugeordnet. Sobald beim Öffnen einer Schublade ein Zapfen in das Kurvenstück eintritt, werden er und damit die Schließstange durch eine schräg ansteigende Führungsfläche angehoben, wobei dann die anderen Zapfen der Schließstange vor die Anschlagflächen der übrigen Schubladen zu liegen kommen und ein Ausziehen derselben verhindern. Um dabei auch ein gleichzeitiges Ausziehen mehrerer Schubladen zu vermeiden, befinden sich die Kurvenstücke in verschiedenen Abständen zur Schließstange, wobei die Kurvenstücke an jeder Schublade unterschiedlich angeordnet sind. Selbst wenn jetzt zwei Schubladen gleichzeitig herausgezogen werden, erfolgt durch die Schublade, an welcher sich das Kurvenstück weiter vorne befindet eine Verriegelung aller anderen Schubladen, bei welchen das Kurvenstück in einem Abstand dahinter angeordnet ist. Die zweite oder eine weitere Schublade können also nur um ein geringes Maß, welches dem Abstand der Anschlagfläche von der Schubladenvorderkante entspricht, aber auf keinen Fall vollständig herausgezogen werden.A construction is already known in which a simultaneous pulling out of several drawers and with an open drawer prevents the opening of further drawers. Here curve pieces are attached to the drawers and the cabinet is provided with vertically displaceable locking bars arranged next to the drawers with projecting pins, a holding device being provided for holding the locking bar in its displaced position. The cam pieces are also associated with stopper interacting with the pin. As soon as a peg enters the cam piece when a drawer is opened, it and thus the locking rod are raised by an obliquely rising guide surface, the other pegs of the locking rod then coming to lie in front of the stop surfaces of the other drawers and preventing them from being pulled out. In order to avoid pulling out several drawers at the same time, the curve pieces are located at different distances from the locking rod, the curve pieces being arranged differently on each drawer. Even if two drawers are now pulled out at the same time, the drawer on which the curve piece is located further forward locks all other drawers in which the curve piece is arranged at a distance behind it. The second or another drawer can therefore only be pulled out completely by a small amount, which corresponds to the distance of the stop surface from the front edge of the drawer.

Die Aufgabe der vorliegenden Erfindung ist es, die Fertigung derartiger Schubladen zu vereinfachen und die Einstellung der Abstände der Kurvenstücke zu erleichtern. Zur Lösung sind die Kurvenstücke und die Stopper an den Schubladen längsverschieb- und feststellbar angeordnet. Man kann nunmehr völlig gleichartige Kurvenstücke verwenden und bei der Fertigung der Schubladen kann der Abstand der Kurvenstücke und der Stopper von der Schubladenvorderkante unberücksichtigt bleiben, so daß also auch die Schubladen völlig einheitlich hergestellt werden können.The object of the present invention is to simplify the manufacture of such drawers and to facilitate the adjustment of the distances between the curve pieces. To solve this, the curve pieces and the stoppers on the drawers are longitudinally displaceable and noticeably arranged. It is now possible to use completely identical curve pieces and the distance between the curve pieces and the stopper from the front edge of the drawer can be disregarded in the manufacture of the drawers, so that the drawers can also be produced completely uniformly.

Vorzugsweise sind die Kurvenstücke und die Stopper fest miteinander verbunden und insbesondere einstückig gefertigt, so daß sie zwangsläufig zusammen miteinander verstellt werden.Preferably, the curve pieces and the stoppers are firmly connected to one another and in particular are made in one piece, so that they are inevitably adjusted together.

Eine besonders einfache Ausführungsform ergibt sich, wenn man die Kurvenstücke in einer Nut der Schublade anordnet und in dieser festklemmt. Zum Festklemmen ist dabei nach einem weiteren Merkmal der Erfindung ein Exzenter vorgesehen, dessen Drehachse etwa senkrecht zum Nutgrund verläuft und dessen Umfang in mindestens einer Stellung an einem der Nutschenkel anliegt. Das Kurvenstück wird nach Lösen des Exzenters innerhalb der Nut in die gewünschte Stellung verschoben und anschließend durch Zurückdrehen des Exzenters in dieser Lage festgeklemmt.A particularly simple embodiment results if the curve pieces are arranged in a groove in the drawer and clamped in this. According to a further feature of the invention, an eccentric is provided for clamping, the axis of rotation of which extends approximately perpendicular to the base of the groove and the circumference of which rests on one of the groove legs in at least one position. After loosening the eccentric, the curve piece is moved into the desired position within the groove and then clamped in this position by turning the eccentric back.

Eine besonders einfache Ausführungsform ergibt sich, wenn man an der dem Nutgrund zugewandten Seite des Kurvenstückes eine zur Gegenseite hin durchbrochene Lagerschale für eine Nabe des Exzenters und an einer zum Nutschenkel gerichteten Fläche einen Durchbruch für den Exzenter vorsieht. Dabei ist der Durchbruch der Lagerschale erforderlich, um den Exzenter von der Außenseite der Schublade her einstellen zu können. Um ein ungewolltes Lösen des Kurvenstückes zu verhindern, ist es zweckmäßig auf seiner, dem Durchbruch für den Exzenter gegenüberliegenden Fläche aufgerauht, mit Rippen oder mit Krallen versehen.A particularly simple embodiment is obtained if, on the side of the curve piece facing the base of the groove, a bearing shell for a hub of the eccentric, perforated towards the opposite side, and an opening for the eccentric on a surface directed towards the groove leg. The opening of the bearing shell is necessary in order to be able to adjust the eccentric from the outside of the drawer. In order to prevent unwanted loosening of the curve piece, it is useful on his, the Breakthrough for the surface opposite the eccentric roughened, provided with ribs or claws.

In Fig. 1 sind die rechts und links neben den Schubladen vertikal angeordneten Schließstangen 1, 2 an ihren, den Schubladen 3 zugewandten Seite mit lotrecht zur Schließstange angeordneten zylindrischen Zapfen 4 versehen. Jede Schließstange 1, 2 besitzt je einen Zapfen 4 für jede Schublade 3. An den rechten und linken Seitenwänden 5, 6 der Schubladen 3 ist je ein Kurvenstück 7 angeordnet. Etwa an der Stirnfläche jeder Seitenwand 5, 6 ist eine Anschlagfläche 10 vorgesehen.In FIG. 1, the closing rods 1, 2 arranged vertically to the right and left of the drawers are provided on their side facing the drawers 3 with cylindrical pins 4 arranged perpendicular to the locking rod. Each locking rod 1, 2 has a pin 4 for each drawer 3. On the right and left side walls 5, 6 of the drawers 3, a curve piece 7 is arranged. A stop surface 10 is provided approximately on the end face of each side wall 5, 6.

Das Kurvenstück 7 enthält eine Rückstellfläche 13 und eine Führungsfläche 14 zur Führung des Zapfens 4 und damit zur Auslenkung der Schließstange 1, 2 beim Herausziehen der Schublade 3. Die Rückstellfläche 13 und die Führungsfläche 14 sind durch eine Rückwand 15 des Kurvenstückes 7 miteinander verbunden. Die Führungsfläche 14 verläuft in Längsrichtung zunächst schräg ansteigend und fällt anschließend wieder auf das Ausgangsniveau ab. Die Rückstellfläche 13 verläuft zunächst parallel zur Führungsfläche 14, jedoch nach Erreichen des höchsten Punktes horizontal bis ans Ende des Kurvenstückes 7 weiter. Das Kurvenstück 7 integriert an seiner Vorderseite einen Stopper 16. Der Stopper 16 ist in der gleichen Höhe angeordnet, wie die Anschlagfläche 10.The curve piece 7 contains a restoring surface 13 and a guide surface 14 for guiding the pin 4 and thus for deflecting the locking rod 1, 2 when the drawer 3 is pulled out. The restoring surface 13 and the guide surface 14 are connected to one another by a rear wall 15 of the curve piece 7. The guide surface 14 initially extends obliquely in the longitudinal direction and then drops again to the initial level. The restoring surface 13 initially runs parallel to the guide surface 14, but continues horizontally to the end of the curve section 7 after reaching the highest point. The curve piece 7 integrates a stopper 16 on its front side. The stopper 16 is arranged at the same height as the stop surface 10.

Die Kurvenstücke 7 sind in verschiedenen Abständen von den Schließstangen 1, 2 angeordnet. Dabei verfügt jede Schublade 3 eines Schubladenschrankes über eine andere Anordnung der Kurvenstücke 7.The curve pieces 7 are arranged at different distances from the locking bars 1, 2. Each drawer 3 of a drawer cabinet has a different arrangement of the curve pieces 7.

Im folgenden wird die Funktionsweise der Schließanlage detailliert beschrieben:
In der Ausgangsstellung, d.h., wenn alle Schubladen geschlossen sind, sind die Schließstangen 1, 2 und ihre Zapfen 4 derart ausgerichtet, daß sich die Zapfen 4 auf der Höhe zwischen dem Anfang der Führungsfläche 14 und der Rückstellfläche 13 befinden. Wird nun eine Schublade 3 herausgezogen, so wird die Anschlagfläche 10 über den Zapfen 4 hinweg geführt und der Zapfen 4 tritt in das Kurvenstück 7 hinein. Die schräg ansteigende Führungsfläche 14 bewegt nun die Schließstange 1, 2 vertikal nach oben, bis diese in eine nicht dargestellte Haltevorrichtung einrastet. In dieser Stellung sind die Zapfen 4 der Schließstangen 1, 2 auf gleicher Höhe mit der Anschlagfläche 10 bzw. des Stoppers 16 und verriegeln somit die übrigen Schubladen. Beim Zuschieben der geöffneten Schublade 3 gelangt der Zapfen 4 der Schließstange 1, 2 in umgekehrter Richtung in das Kurvenstück 7. Die parallel zur Führungsfläche 14 verlaufende Rückstellfläche 13 drückt nun die Schließstange 1, 2 mittels des Zapfens 4 aus der nicht dargestellten Haltevorrichtung heraus und bewegt die Schließstange 1, 2 zurück in die Ausgangsstellung. Somit sind sämtliche Schubladen 3 wieder entriegelt und es kann eine beliebige Schublade 3 herausgezogen werden.The functioning of the locking system is described in detail below:
In the starting position, ie when all drawers are closed, the locking bars 1, 2 and their pins 4 are aligned such that the pins 4 are at the level between the beginning of the guide surface 14 and the restoring surface 13. If a drawer 3 is now pulled out, the stop surface 10 is guided over the pin 4 and the pin 4 enters the curve piece 7. The obliquely rising guide surface 14 now moves the locking bar 1, 2 vertically up until it snaps into a holding device, not shown. In this position, the pins 4 of the locking rods 1, 2 are at the same level with the stop surface 10 or the stopper 16 and thus lock the other drawers. When the opened drawer 3 is pushed in, the pin 4 of the locking rod 1, 2 reaches the cam piece 7 in the opposite direction. The restoring surface 13 running parallel to the guide surface 14 now presses the locking rod 1, 2 out of the holding device (not shown) and moves the locking rod 1, 2 back to the starting position. All drawers 3 are thus unlocked again and any drawer 3 can be pulled out.

Beim gleichzeitigen Herausziehen zweier Schubladen 3 wird durch die unterschiedliche Kombination der Kurvenstücke 7 an jeder Schublade 3, spätestens nachdem die Schubladen um den Abstand 17 geöffnet sind, eine Schublade 3 verriegelt sein. Die individuelle Anordnung der Kurvenstücke 7 an den Schubladen 3 bewirkt, daß die Schließstangen 1, 2 von jeder Schublade 3 in einer anderen Kombination ausgelenkt werden und somit ist es nicht möglich, zwei Schubladen 3 gleichzeitig herauszuziehen.When two drawers 3 are pulled out at the same time, a drawer 3 will be locked by the different combination of the curved pieces 7 on each drawer 3, at the latest after the drawers are opened by the distance 17. The individual arrangement of the curved pieces 7 on the drawers 3 causes the locking bars 1, 2 to be deflected by each drawer 3 in a different combination and thus it is not possible to pull out two drawers 3 at the same time.

Um die Lage der Kurvenstücke 7 und der Stopper 16, welche an diesen angeformt sind, beliebig einstellen zu können, sind die Kurvenstücke 7 in Nuten 18 der Schubladenseitenwände 5, 6 verschiebbar und festklemmbar gelagert. Wie die Fign. 2 bis 4 zeigen, wird hierzu ein Exzenter 19 verwendet, welcher mit seiner Nabe 20 in einer Lagerschale 21 der Rückwand 15 des Kurvenstückes 7 drehbar gelagert ist. Dabei ist die Lagerschale 21 nach außen hin durchbrochen, damit man ein nicht dargestelltes Werkzeug, insbesondere einen Schraubenzieher hindurchführen und in den Schlitz 23 des Exzenters einführen kann, um diesen in die gewünschte Stellung zu drehen. Die Achse der Lagerschale 21 verläuft dabei senkrecht zum Nutgrund 22 der Nut 18. Die Kurvenstücke 7 sind an ihrer Oberseite mit einem Durchtritt 29 für den Exzenter 19 versehen. Wenn dieser in eine entsprechende Stellung gedreht wird, in welche ein Teil seines Umfanges aus der Oberseite 24 des Kurvenstückes 7 austritt, stützt er sich an dem oberen Schenkel der Nut 25 ab und preßt die Unterseite 26 des Kurvenstückes 7 gegen den unteren Nutschenkel 27, so daß das Kurvenstück innerhalb der Nut 18 festgelegt wird. Um eine sichere Befestigung zu erhalten, ist die Unterseite 26 des Kurvenstückes, insbesondere an den beiden Enden, mit Krallen 28 versehen.In order to be able to adjust the position of the curve pieces 7 and the stopper 16, which are integrally formed thereon, as desired, the curve pieces 7 are mounted in grooves 18 of the drawer side walls 5, 6 so as to be displaceable and clampable. As the fig. 2 to 4 show, an eccentric 19 is used for this purpose, which can be rotated with its hub 20 in a bearing shell 21 of the rear wall 15 of the curve piece 7 is stored. The bearing shell 21 is perforated outwards so that a tool (not shown), in particular a screwdriver, can be passed through and inserted into the slot 23 of the eccentric in order to rotate it into the desired position. The axis of the bearing shell 21 extends perpendicular to the groove base 22 of the groove 18. The curve pieces 7 are provided on their upper side with a passage 29 for the eccentric 19. If this is rotated into a corresponding position, in which a part of its circumference emerges from the top 24 of the curve piece 7, it is supported on the upper leg of the groove 25 and presses the bottom 26 of the curve piece 7 against the lower groove leg 27, so that the curve piece is fixed within the groove 18. In order to obtain a secure attachment, the underside 26 of the curve piece, in particular at the two ends, is provided with claws 28.

Diese verschiebbare Anordnung der Kurvenstücke 7 mit den Stoppern 16 ermöglicht es, völlig gleichartige Schubladen herzustellen, wobei der richtige Abstand der Kurvenstücke 7 und der Stopper 16 zu den Zapfen 4 der Schließstangen 1 und 2 bei der Montage der Schubladen beliebig eingestellt werden kann.This displaceable arrangement of the curve pieces 7 with the stoppers 16 makes it possible to produce completely identical drawers, the correct distance between the curve pieces 7 and the stopper 16 from the pins 4 of the locking bars 1 and 2 being able to be set as desired when the drawers are being installed.

Wenn man die Kurvenstücke 7 aus Kunststoff fertigt, besteht die Gefahr, daß der Kunststoff im Laufe der Zeit, insbesondere bei Temperatureinwirkung nachgibt und die Klemmwirkung nur noch unzureichend ist. Um eine unbedingte Sicherheit gegen jegliches Verschieben zu erhalten, ist daher nach einem weiteren Merkmal der Erfindung zwischen der Nabe 20 des Exzenters 19 und der dem Durchtritt 29 für den Exzenter 19 gegenüberliegenden Fläche 26 des Kurvenstückes 7 eine in Fig. 5 und in Fig. 2 gestrichelt dargestellte, aus Stahlblech bestehende Stützplatte 30 vorgesehen. Diese liegt an der Rückwand 15 des Kurvenstückes 7 an, wobei an der Stützplatte Nasen 31 vorgesehen sind, welche sich in die Rückwand 15 einpressen und dadurch eine nahezu unverschiebbare Verbindung herstellen. Auch hier ist, um ein Verrutschen gegenüber dem unteren Nutschenkel 27 zu verhindern, das untere Ende 32 verzahnt.If the curve pieces 7 are made of plastic, there is a risk that the plastic will give way over time, particularly when exposed to temperature, and that the clamping effect is only insufficient. In order to obtain an unconditional security against any displacement, is therefore according to a further feature of the invention between the hub 20 of the eccentric 19 and the Passage 29 for the eccentric 19 opposite surface 26 of the curve piece 7 is provided in FIG. 5 and in FIG. 2 in dashed lines, made of sheet steel support plate 30. This rests on the rear wall 15 of the curve piece 7, lugs 31 being provided on the support plate, which are pressed into the rear wall 15 and thereby produce an almost immovable connection. Here, too, in order to prevent slipping relative to the lower groove leg 27, the lower end 32 is toothed.
