  • the open side of the storage compartment is always directed towards the feed rollers.
  • the feed rollers transport the data carrier in the same direction to the two normal positions of the storage compartment, i.e. neutral.

Description

Die Erfindung betrifft eine Ablagevorrichtung für aus einem Druckwerk ausgeworfene Datenträger mit einem Ablagefach und zwei an dessen Unterseite angeordneten Zuführrollen, wobei der Datenträger nach seiner Zuführung mit der Unterkante über eine dieser Rollen umgelenkt und auf dem gegenüber der Zuführrichtung geneigten Ablagefach abgelegt wird.The invention relates to a storage device for ejected from a printing unit with a storage compartment and two feed rollers arranged on the underside thereof, the data carrier being deflected with its lower edge over one of these rollers and being placed on the storage compartment inclined relative to the feed direction.

Eine derartige Ablagevorrichtung ist aus der DE-AS 2606697 bekannt, die ein Teil einer Vorsteckeinrichtung ist. Nach dem Beschriften eines Datenträgers wird dieser durch das Druckwerk nach oben ausgeworfen und von zwei Zuführrollen erfasst, die den Datenträger dem Ablagefach zuführen. Durch sein Eigengewicht wird der Datenträger mit seiner Unterkante über die eine Zuführrolle geführt und fällt anschliessend in das zur Ebene der Zuführrollen schräg geneigte Ablagefach, das ortsfest auf der Vorsteckeinrichtung angeordnet ist. Die beiden Zuführrollen sind leicht gegeneinander bezogen auf das Ablagefach versetzt, so dass der Datenträger stets nach einer Richtung transportiert wird.Such a storage device is known from DE-AS 2606697, which is part of a plug-in device. After a data carrier has been labeled, it is ejected upwards by the printing unit and captured by two feed rollers which feed the data carrier to the storage compartment. Due to its own weight, the lower edge of the data carrier is guided over the one feed roller and then falls into the storage compartment, which is inclined at an angle to the level of the feed rollers and is arranged in a fixed manner on the plug-in device. The two feed rollers are slightly offset from each other in relation to the storage compartment, so that the data carrier is always transported in one direction.

Aus der DE-OS 2 222 596 ist weiterhin eine Ablagevorrichtung bekannt, bei der die zugeführten Datenträger durch ein oder mehrere vorgespannte Blattfedern gegen den ortsfest angeordneten Boden des Ablagefaches gedrückt werden. Sie setzen dadurch der Einführung des Datenträgers einen Widerstand entgegen. Aus diesem Grunde ist eine der beiden Zuführungsrollen klinkenförmig ausgebildet.A storage device is also known from DE-OS 2 222 596, in which the supplied data carriers are pressed against the fixed bottom of the storage compartment by one or more prestressed leaf springs. In doing so, they oppose the introduction of the data carrier. For this reason, one of the two feed rollers is pawl-shaped.

Nachteilig dabei ist, dass die Zuführrollen zwangsläufig den Datenträger stets in eine Richtung zum fest angeordneten Ablagefach ablenken. Ausserdem ist bei der zweitgenannten Anordnung eine Beschädigung oder Knickung des Datenträgers nicht ausgeschlossen.The disadvantage here is that the feed rollers always deflect the data carrier in one direction to the fixed storage compartment. In addition, damage or kinking of the data carrier is not ruled out in the second arrangement.

Der Erfindung liegt die Aufgabe zugrunde, ein Ablagefach und deren Zuführung für den Datenträger so zu gestalten, dass die Ablage der Datenträger bedarfsweise einmal mit ihren Vorderseiten nach vorn und zum anderen mit ihren Rückseiten nach vorn liegen. Dadurch wird es möglich, die Reihenfolge der Ablage der Datenträger so zu wählen, dass entweder stets der zuletzt beschriftete Datenträger mit seiner Vorderseite sichtbar ist oder dass sie in der Reihenfolge abgelegt werden, die der Abnahme vor dem Beschriften aus einem Zuführfach entspricht. Unter Datenträger wird ein einzelnes Blatt, Formularsätze aus mehreren Lagen oder auch Briefumschläge verstanden.The invention is based on the object of designing a storage compartment and its feed for the data carrier in such a way that the storage of the data carriers, if necessary, is once with their front sides forward and the other with their rear sides forward. This makes it possible to choose the order in which the data carriers are stored in such a way that either the last labeled data carrier is always visible with its front side, or that it is stored in the order that corresponds to the acceptance before being labeled from an input tray. A data carrier is understood to mean a single sheet, form sets from several layers or envelopes.

Diese Aufgabe wird dadurch gelöst, dass das Ablagefach als abnehmbarer Kasten ausgebildet ist, dass symmetrisch zu den Zuführrollen beidseitig je ein Aufstecklager zum bedarfsweisen Anordnen des Ablagefaches auf der einen oder anderen Seite der Zuführrollen angeordnet ist, dass die Zuführrollen den Datenträger in der Symmetrieebene der Aufstecklager transportieren und dass das Ablagefach ein oder mehrere Ablenkmittel besitzt, die bis in die Symmetrieebene der Zuführrollen reichen und dass dadurch der Datenträger über die zum Inneren des Ablagefaches weisende Zuführrolle in das Ablagefach abgelenkt wird. Dadurch wird es möglich, das Ablagefach mit seiner Unterkante bedarfsweise auf dem einen Aufstecklager oder nach Drehen um 180° mit der gleichen Unterseite auf dem anderen Aufstecklager abzustellen. Dabei ist die offene Seite des Ablagefaches stets zu den Zuführrollen gerichtet. Die Zuführrollen befördern den Datenträger in eine zu den beiden π1ögliohen Lagen des Ablagefaches gleiche Richtung, d.h. neutral.This object is achieved in that the storage compartment is designed as a removable box, that a push-on bearing is arranged on both sides symmetrically to the feed rollers for arranging the storage compartment on one side or the other of the feed rollers as required, that the feed rollers hold the data carrier in the plane of symmetry of the push-on bearings transport and that the storage compartment has one or more deflecting means which extend into the plane of symmetry of the feed rollers and that the data carrier is thereby deflected into the storage compartment via the feed roller pointing towards the interior of the storage compartment. This makes it possible, if necessary, to place the storage compartment with its lower edge on one plug-in bearing or after rotating it through 180 ° with the same underside on the other plug-in bearing. The open side of the storage compartment is always directed towards the feed rollers. The feed rollers transport the data carrier in the same direction to the two normal positions of the storage compartment, i.e. neutral.

Für relativ instabile Datenträger, z.B. weiche Formularsätze oder geknitterte Blätter, muss der Ablageschacht des Ablagefaches schmal gehalten werden. Dies wird erreicht, wenn das Ablagefach einen schwenkbaren Einlagebogen besitzt, der durch Federkraft gegen die zum Inneren des Ablagefaches weisende Zuführrolle vorgespannt ist. Dadurch bleibt der schmale Ablageschacht bis zur vollständigen Füllung des Ablagefaches konstant.For relatively unstable data carriers, e.g. soft form sets or wrinkled sheets, the storage compartment of the storage compartment must be kept narrow. This is achieved when the storage compartment has a pivotable insert sheet which is spring-biased against the feed roller pointing towards the interior of the storage compartment. This keeps the narrow storage slot constant until the storage compartment is completely filled.

Die Erfindung hat ausserdem den Vorteil, dass bei Verwendung mehrerer gleicher Ablagefächer der Stapel Datenträger nicht dem Ablagefach entnommen werden muss, sondern mit diesem zusammen bis zum nächsten Gebrauch abgelegt werden kann. Bei entsprechender Ausbildung der Zuführeinrichtung kann dieses Ablagefach dann auch als Zuführfach genützt werden.The invention also has the advantage that when using several identical storage compartments, the stack of data carriers does not have to be removed from the storage compartment, but can be stored together with it until the next use. If the feed device is designed accordingly, this storage compartment can then also be used as a feed compartment.

Gemäss weiterer Ausbildung der Erfindung ist oberhalb der Zuführrollen und in der Symmetrieebene eine Welle angeordnet, auf der ein Doppelhebel befestigt ist, von dem ein Arm in das Ablagefach unabhängig von dessen Lage zu den Zuführrollen derart hineinragt, dass bei vollem Ablagefach der Doppelhebel verschwenkt wird und dadurch einen ausserhalb des Ablagefaches angeordneten ortsfesten Schalter betätigt. Mit der Ablage des letzten Datenträgers einer vorbestimmten Anzahl Datenträger wird somit ein volles Ablagefach signalisiert und eine weitere Ablage unterbunden werden können.According to a further embodiment of the invention, a shaft is arranged above the feed rollers and in the plane of symmetry, on which a double lever is fastened, from which an arm projects into the storage compartment regardless of its position in relation to the feed rollers in such a way that the double lever is pivoted when the storage compartment is full and thereby actuating a stationary switch arranged outside the storage compartment. With the storage of the last data carrier of a predetermined number of data carriers, a full storage compartment is thus signaled and further storage can be prevented.

Da einerseits der Transport des Datenträgers zu den Lagen des Ablagefaches neutral erfolgt und andererseits die Welle des Doppelhebels aus den gleichen Gründen in dieser Transportbahn liegt, besteht die Gefahr, dass der Datenträger in die falsche Richtung abgelenkt werden kann. Ein Zurückführen in die gewünschte Richtung ist dann nicht mehr möglich. Aus diesem Grunde wird auf die Welle ein zweiter Doppelhebel als Ablenkmittel lose drehbar aufgebracht, der zwangsweise durch Aufstecken des Ablagefaches so verschwenkt wird, dass der Datenträger, bevor dessen Oberkante den Bereich der Welle erreicht, bereits in die gewünschte Richtung auf das Ablagefach hin bewegt wird. Beide Doppelhebel sind unabhängig voneinander verschwenkbar.Since on the one hand the transport of the data carrier to the positions of the storage compartment takes place neutrally and on the other hand the shaft of the double lever lies in this transport path for the same reasons, there is a risk that the data carrier can be deflected in the wrong direction. A return in the desired direction is then no longer possible. For this reason, a second double lever as a deflecting means is loosely rotatably attached to the shaft, which is forcibly pivoted by plugging the storage compartment in such a way that the data carrier is already moved in the desired direction towards the storage compartment before its upper edge reaches the area of the shaft . Both double levers can be pivoted independently of one another.

Die Erfindung wird anhand eines Ausführungsbeispieles näher beschrieben. Es zeigen:

  • Fig. 1 die Ablagevorrichtung gemäs der Erfindung mit dem Ablagefach in der hinteren Stellung,
  • Fig. die Ablagevorrichtung mit dem Ablagefach in der vorderen Stellung nach Verdrehung um 180°,
  • Fig. 3 die Ablagevorrichtung gemäss Fig. 1 teilweise im Schnitt,
  • Fig. 4 die Vorderansicht der Ablagevorrichtung gemäss Fig. 1 und
  • Fig. 5 eine teilweise Draufsicht der Ablagevorrichtung.
The invention is described in more detail using an exemplary embodiment. Show it:
  • Fig. 1, the storage device according to the invention with the storage compartment in the rear Stel lung,
  • 1 shows the storage device with the storage compartment in the front position after rotation by 180 °,
  • 3 shows the storage device according to FIG. 1, partly in section,
  • 4 shows the front view of the storage device according to FIGS. 1 and
  • Fig. 5 is a partial plan view of the storage device.

Bei dem dargestellten Ausführungsbeispiel wird die Vereinzelungsvorrichtung oberhalb des Druckwerkes, von dem nur die Schreibwalze 15 und deren Andruckrollen 14 dargestellt sind, abnehmbar aufgesteckt, so dass die abzulegenden Datenträger 8 der Vorrichtung von unten zugeführt werden. Dabei ist es unbedeutend, auf welche Weise die Datenträger der Schreibwalze für die Beschriftung zugeführt werden. Der Führung der Datenträger zur Schreibwalze und zu den Zuführrollen dienen die Leitbleche 11 und 12, die Teile des Aufstecklagers 9 für das auswechselbare Ablagefach 4 sind, der kastenförmig ausgebildet ist.In the illustrated embodiment, the separating device above the printing unit, of which only the platen roller 15 and its pressure rollers 14 are shown, is detachably attached, so that the data carriers 8 to be stored are fed to the device from below. It is irrelevant in which way the data media are fed to the platen for labeling. The guide plates 11 and 12, which are parts of the plug-on bearing 9 for the exchangeable storage compartment 4, which is box-shaped, serve to guide the data carriers to the platen roller and to the feed rollers.

Die Vorrichtung wird gebildet aus den beiden Seitenwänden 23 und 24, die durch die Leitbleche 11 und 12 und das Verbindungsblech 13 zusammengehalten werden. In den Seitenwänden 23 und 24 ist die Antriebswelle 10 gelagert, auf der zwei oder mehrere Zuführrollen 1 angeordnet sind. Jeder Zuführrolle 1 ist eine weitere Zuführrolle 1 a zugeordnet, die jeweils auf gesonderten Lagerwellen 10a drehbar gelagert sind. Anstelle einzelner Lagerwellen kann auch eine durchgehende Achse 10a verwendet werden. Weiterhin ist in der Seitenwand 23 eine Schaltwelle 17 einseitig gelagert, auf deren Seite, die in das Ablagefach 4 hineinragt, zwei Doppelhebel 18 und 20 angeordnet sind, und auf deren aus der Vorrichtung herausragenden Seite ein Exzenter 21 befestigt ist, der einen Schalter 22 betätigt.The device is formed from the two side walls 23 and 24, which are held together by the guide plates 11 and 12 and the connecting plate 13. In the side walls 23 and 24, the drive shaft 10 is mounted, on which two or more feed rollers 1 are arranged. Each feed roller 1 is assigned a further feed roller 1 a, which are each rotatably mounted on separate bearing shafts 10 a. Instead of individual bearing shafts, a continuous axis 10a can also be used. Furthermore, a switching shaft 17 is mounted on one side in the side wall 23, on the side which protrudes into the storage compartment 4, two double levers 18 and 20 are arranged, and on the side protruding from the device, an eccentric 21 is fastened, which actuates a switch 22 .

Weiterhin besitzen die Seitenwände 23 und 24 jeweils ein Noppenpaar 25 bzw. 25a, die zur Halterung des Ablagefaches 4 dienen. Hierzu besitzt das Ablagefach 4 an seinen schmalen Seitenwänden jeweils einen Halteschlitz 26 und 26a. Dieser Halteschlitz mündet trompetenartig in den Kastenboden 3, so dass nach Einführung des Ablagefaches 4 zwischen die Seitenwände 23 und 24 die Noppen 25 bzw. 25a in die Schlitze 26 und 26a hineingeführt werden. Das Ablagefach 4 wird so weit zwischen die Seitenwände 23 und 24 eingeführt, bis der Kastenboden auf dem Aufstecklager 9 aufliegt. Aufstecklager 9 und Kastenboden 3 sind so ausgeführt, dass ein Verrutschen des Ablagekastens 4 auf dem Aufstecklager 9 nicht möglich ist.Furthermore, the side walls 23 and 24 each have a pair of knobs 25 and 25a, which serve to hold the storage compartment 4. For this purpose, the storage compartment 4 has a holding slot 26 and 26a on its narrow side walls. This holding slot opens like a trumpet into the box bottom 3, so that after the insertion of the storage compartment 4 between the side walls 23 and 24 the knobs 25 and 25a are inserted into the slots 26 and 26a. The storage compartment 4 is inserted between the side walls 23 and 24 until the box bottom rests on the push-on bearing 9. Push-on bearing 9 and box base 3 are designed so that slipping of the storage box 4 on the push-on bearing 9 is not possible.

Das Verbindungsblech 13 besitzt eine dem Aufstecklager 9 gleiches Lager 9a, auf der der Ablagekasten 4 ebenfalls aufgesetzt werden kann. Befindet sich das Ablagefach 4 in der in Fig. 1 dargestellten Stellung, so kann es dadurch in die in Fig. dargestellte Stellung gebracht werden, dass es nach oben aus der Vorrichtung herausgezogen wird, um seine Längsachse um 180° verdreht wird und anschliessend von oben in die Seitenwände 23 und 24 auf die Noppen 25a wieder aufgesteckt wird bis sein Kastenboden 3 auf dem Lager 9a aufliegt.The connecting plate 13 has a bearing 9a which is the same as the plug-on bearing 9 and on which the storage box 4 can also be placed. If the storage compartment 4 is in the position shown in FIG. 1, it can be brought into the position shown in FIG. 1 by pulling it upward out of the device, rotating it about its longitudinal axis by 180 ° and then from above is pushed back into the side walls 23 and 24 on the knobs 25a until its box bottom 3 rests on the bearing 9a.

Um diese wechselseitige Verwendung des Ablagefaches 4 zu erreichen, müssen die Zuführrollen 1 und 1 derart zwischen den Lagern 9 und 9a angeordnet werden, dass die Ebene durch die Berührungstangente beider Zuführrollen 1 und 1a a symmetrisch zu den Aufstecklagern liegt. Ausserdem liegen die Zuführrollen 1 und 1a oberhalb der Aufstecklager 9 und 9a, so dass sie bei aufgestecktem Ablagefach 4 teilweise in diesen hineinragen. Ausserdem besitzt das Verbindungsblech 13 eine Zuführkante 28, die so angeordnet ist, dass zwangsläufig der über das Leitblech 12 zugeführte Datenträger in die Tangentialebene der Zuführrollen geleitet wird. Bewegen sich die Zuführrollen 1 und 1a in Pfeilrichtung, so wird der Aufzeichnungsträger durch die über den Rollen befindliche Vorderwand 7 des Ablagefaches in dieses hineingelenkt. Dabei besteht die Gefahr, dass der Datenträger, sobald dessen untere Kante zwischen den Zuführrollen hindurchbewegt ist mit seiner unteren Kante auf der linken Zuführrolle 1a aufliegt und durch dessen Bewegung nicht in den Kasten zur Ablage geführt wird, sondern von dieser Ablage weg. Um dies zu verhindern, ist oberhalb der Zuführrollen 1 und 1 a ein als Weiche wirkender Doppelhebel 18 auf der Schaltwelle 17 frei beweglich gelagert. Diese Weiche 18 wird durch die Kante der Vorderseite 7 so auf der Schaltwelle 17 verschwenkt, dass unabhängig davon, ob das Ablagefach 4 in der hinteren (Fig.1) oder vorderen Stellung (Fig.2) eingesteckt ist, die Längsachse dieses Doppelhebels 18 stets in das Ablagefach 4 weist. Dadurch wird zwangsläufig der zugeführte Datenträger stärker in Richtung auf die Ablage ausgelenkt und sichergestellt, dass die Unterkante des Datenträgers von der Zuführrolle 1 und nicht von der Zuführrolle 1a mitgenommen wird. In der Stellung des Ablagefaches 4 gemäss Fig. 2 wird die Unterkante des Datenträgers selbstverständlich von der Zuführrolle 1a und nicht von der Zuführrolle 1 mitgenommen. Diese Bewegung des Datenträgers wird unterstützt durch die innerhalb des Ablagefaches 4 angeordneten Leitfedern 2. Zweckmässig werden diese Leitfedern 2 derart leicht vorgespannt, dass sie unter leichter Kraft auf den Wellen 10 bzw. 10a aufliegen. Auch ist es zweckmässig, jeder Zuführrolle seitlich eine Leitfeder zuzuordnen.In order to achieve this mutual use of the storage compartment 4, the feed rollers 1 and 1 must be arranged between the bearings 9 and 9a in such a way that the plane lies symmetrically to the plug-on bearings due to the contact tangent of both feed rollers 1 and 1a. In addition, the feed rollers 1 and 1a are located above the plug-on bearings 9 and 9a, so that they partially protrude into the storage compartment 4 when they are attached. In addition, the connecting plate 13 has a feed edge 28 which is arranged such that the data carrier supplied via the guide plate 12 is inevitably guided into the tangential plane of the feed rollers. If the feed rollers 1 and 1a move in the direction of the arrow, the recording medium is guided into the storage compartment by the front wall 7 located above the rollers. There is a risk that the data carrier, as soon as its lower edge is moved between the feed rollers, rests with its lower edge on the left feed roller 1 a and is not guided into the box for storage by its movement, but away from this storage. To prevent this, a double lever 18 acting as a switch is mounted on the selector shaft 17 in a freely movable manner above the feed rollers 1 and 1 a. This switch 18 is pivoted by the edge of the front 7 on the control shaft 17 so that regardless of whether the storage compartment 4 is inserted in the rear (Fig.1) or front position (Fig.2), the longitudinal axis of this double lever 18 is always points into the storage compartment 4. As a result, the supplied data carrier is inevitably deflected towards the storage area and it is ensured that the lower edge of the data carrier is taken along by the feed roller 1 and not by the feed roller 1a. In the position of the storage compartment 4 according to FIG. 2, the lower edge of the data carrier is of course carried along by the feed roller 1a and not by the feed roller 1. This movement of the data carrier is supported by the guide springs 2 arranged inside the storage compartment 4. These guide springs 2 are expediently preloaded in such a way that they rest on the shafts 10 and 10a with slight force. It is also expedient to laterally assign a guide spring to each feed roller.

Für eine gute Ablage der Datenträger, insbesondere wenn es sich um sperrige Datenträger wie beispielsweise Formularsätze oder Briefumschläge handelt, ist es wichtig, dass der Zwischenraum zwischen dem obersten abgelegten Datenträger und der nahe gelegenen Zuführrolle 1 bzw. 1a nur ein sehr geringer Abstand ist. Um dies zu erreichen ist, wie aus Fig. 3 ersichtlich, innerhalb des Ablagefaches 4 ein federnder Einlagebogen 5 um den Lagerpunkt 16 drehbar angeordnet. Die Feder 6 sorgt dafür, dass stets der oberste Datenträger leicht an der Zuführrolle 1 bzw. 1a anliegt. Solange das Ablagefach 4 nicht gefüllt ist, wird durch die zugeführten Datenträger der Doppelhebel 20, der drehfest mit der Schaltwelle 17 verbunden ist, nur geringfügig ausgelenkt, so dass über den Exzenter 21 keine Funktionsauslösung des Schalters 22 erfolgt. Ist dagegen das Ablagefach 4 gefüllt, so wird mit steigender Anzahl abgelegter Datenträger der Doppelhebel 20 schliesslich in die in Fig. 3 punktiert gezeichnete Lage verschwenkt. Dadurch wird nun über den Exzenter 21 der Schalter 22 betätigt und die Zufuhr weiterer Datenträger gestoppt.For a good storage of the data carriers, especially when it comes to bulky data carriers such as form sets or envelopes, it is important that the space between the uppermost stored data carrier and the nearby feed roller 1 or 1a is only a very small distance. In order to achieve this, as can be seen from FIG. 3, a resilient insert sheet 5 is arranged rotatably about the bearing point 16 within the storage compartment 4. The spring 6 ensures that the top data carrier lies lightly on the feed roller 1 or 1a. As long as the storage compartment 4 is not filled, the double lever 20, which is non-rotatably connected to the control shaft 17, is only slightly deflected by the supplied data carriers, so that the eccentric 21 does not trigger the switch 22. If, on the other hand, the storage compartment 4 is filled, the double lever 20 is finally pivoted into the position shown in dotted lines in FIG. 3 with an increasing number of stored data carriers. As a result, the switch 22 is now actuated via the eccentric 21 and the supply of further data carriers is stopped.

Die Leitfedern 2 liegen auf den Wellen 10 bzw. 10a unter leichter Vorspannung auf. Die Länge ist so gewählt, dass sie bei Auslenkung durch die Oberkante des zugeführten Datenträgers gegen die Unterseite der anderen Welle 10a bzw. 10 anliegt und über die Oberfläche der anderen Zuführrolle 1 bzw. 1a angehoben ist und somit den Weg für den Datenträger freigibt. Dadurch wird die Unterkante des zugeführten Aufzeichnungsträgers auf die Oberfläche der transportierenden Zuführrolle 1 bzw. 1 a geführt.The guide springs 2 rest on the shafts 10 and 10a with a slight preload. The length is selected so that it bears against the underside of the other shaft 10a or 10 when it is deflected by the upper edge of the supplied data carrier and is raised above the surface of the other feed roller 1 or 1a and thus clears the way for the data carrier. As a result, the lower edge of the supplied recording medium is guided onto the surface of the transporting feed roller 1 or 1 a.

Um ein Überschwenken des Doppelhebels 18 beim Aufsetzen des Ablagefaches 4 zu verhindern, ist in der Seitenwand 23 zusätzlich ein Bolzen 19 angeordnet, gegen den der Doppelhebel 18 zu liegen kommt, wenn sie durch die freie Kante der Vorderseite 7 des Ablagefaches 4 verschwenkt wird.In order to prevent the double lever 18 from being pivoted over when the storage compartment 4 is placed in place, a bolt 19 is additionally arranged in the side wall 23, against which the double lever 18 comes to rest when it is pivoted by the free edge of the front side 7 of the storage compartment 4.

Die Vorderseite 7 des Ablagefaches 4 besitzt Schlitze 27, um das Verschwenken der Doppelhebei 20 nicht zu behindern.The front 7 of the storage compartment 4 has slots 27 in order not to hinder the pivoting of the double lifting 20.
