Description

Die Erfindung bezieht sich auf eine Schublade, welche gegenüber einem Möbelkorpus verfahrbar ist, mit einer Vorrichtung zur Stabilisierung des Laufverhaltens der Schublade gegenüber dem Möbelkorpus, wobei an beiden Seiten der Schublade ein Zahnrad gelagert ist und die beiden Zahnräder, die drehfest miteinander verbunden sind, mit korpusseitigen Zahnstangen kämmen.The invention relates to a drawer, which is movable relative to a furniture body, with a device for stabilizing the running behavior of the drawer relative to the furniture body, wherein on both sides of the drawer a gear is mounted and the two gears, which are rotatably connected to each other, with combing body-side racks.

Insbesondere bei sehr schmalen oder sehr breiten Schubladen ist es vorteilhaft, eine Seitenstabilisierung für eine Schublade vorzusehen, die ein seitliches Verkanten der Schublade verhindert. Aus der US-PS 2,214,291 ist ein Möbelkorpus mit Schubladen bekannt, wobei im Möbelkorpus Zahnstangen vorgesehen sind, an denen an den Schubladen gelagerte Zahnräder ablaufen. Die Zahnräder sind an gegenüberliegenden Seiten der Schublade angeordnet und beispielsweise über eine Stange miteinander verbunden. Eine derartige Parallelauszugsführung ist auch aus der EP 0 875 178 A2 bekannt.Especially with very narrow or very wide drawers, it is advantageous to provide a lateral stabilization for a drawer, which prevents lateral tilting of the drawer. From the U.S. Patent 2,214,291 a furniture carcass with drawers is known, wherein in the furniture body racks are provided, run off at which mounted on the drawers gears. The gears are arranged on opposite sides of the drawer and connected to each other, for example via a rod. Such a parallel pullout guide is also from the EP 0 875 178 A2 known.

Aufgabe der Erfindung ist es, die Schublade der eingangs erwähnten Art dahingehend zu verbessern, dass das Einhängen derselben erleichtert wird. Dabei soll es möglich sein, die seitliche Ausrichtung einer etwas schräg in den Möbelkorpus eingeführten Schublade zu korrigieren.The object of the invention is to improve the drawer of the type mentioned in that the suspension is facilitated. It should be possible to correct the lateral orientation of a slightly obliquely introduced into the furniture body drawer.

Die erfindungsgemäße Aufgabe wird dadurch gelöst, dass an jeder Zahnstange mindestens ein an das hintere Ende der Zahnreihe anschließender durch das Zahnrad relativ zur Zahnstange bewegbarer Zahn vorgesehen ist. Der bewegbare Zahn erlaubt ein "Überspringen" von Zähnen am Zahnrad und der Zahnstange und damit eine Korrektur der Lage einer allenfalls schräg eingeführten Schublade.The object of the invention is achieved in that at least one subsequent to the rear end of the row of teeth is provided by the gear relative to the rack movable tooth on each rack. The movable tooth allows a "skipping" of teeth on the gear and the rack and thus a correction of the position of a possibly obliquely introduced drawer.

Eine Schublade 3 ist mittels einer herkömmlichen Ausziehführungsgarnitur 4 zwischen den Seitenwänden 1 eines Möbelkorpus verfahrbar.A drawer 3 is movable by means of a conventional Ausziehführungsgarnitur 4 between the side walls 1 of a furniture body.

Bei der Ausziehführungsgarnitur 4 kann es sich sowohl um einen Einfachauszug mit einer korpusseitigen Tragschiene und einer ladenseitigen Schublade an beiden Seiten der Schublade oder um einen Vollauszug handeln, bei dem zwischen der korpusseitigen Tragschiene und der ladenseitigen Ausziehschiene eine Mittelschiene gelagert ist.In the Ausziehführungsgarnitur 4 may be both a single extension with a body-side mounting rail and a loading-side drawer on both sides of the drawer or a full extension, in which a middle rail is mounted between the body-side mounting rail and the loading side pull-out.

Unterhalb der korpusseitigen Tragschiene sind an den Seitenwänden 1 Zahnstangen 5 befestigt, die mit Zähnen 17, 18 versehen sind.Below the body-side mounting rail 1 racks 5 are attached to the side walls, which are provided with teeth 17, 18.

Mit den Zähnen 17, 18 der Zahnstangen 5 kämmen Zahnräder 10, die an beiden Seiten der Schublade 3 gelagert sind.With the teeth 17, 18 of the racks 5 mesh gears 10, which are mounted on both sides of the drawer 3.

Die Zahnräder 10 lagern mittels ihrer Steckachsen 27 in Lagerkörpern 7, die wiederum in Halterungen 6 höhenverschiebbar gelagert sind. Die Lagerkörper 7 sind dabei in den Haltekörpern 6 beispielsweise mittels einer Schwalbenschwanzführung 26 geführt.The gears 10 store by means of their stub axles 27 in bearing bodies 7, which in turn are mounted vertically displaceable in brackets 6. The bearing body 7 are guided in the holding bodies 6, for example by means of a dovetail guide 26.

Die Halterungen 6 sind an der Schublade 3, vorzugsweise an den Schubladenzargen 2 befestigt. Im Ausführungsbeispiel sind die Schubladenzargen 2 mit einem hinteren abgewinkelten Steg 28 versehen, auf den die Halterungen 6 aufgeschoben sind.The brackets 6 are attached to the drawer 3, preferably to the drawer 2. In the exemplary embodiment, the drawer 2 are provided with a rear angled web 28 on which the brackets 6 are pushed.

Die Steckachsen 27 der Zahnräder 10 ragen durch die Lagerkörper 7 hindurch und in eine hülsenförmige Stange 11, die zumindestens in ihren beiden Endbereichen mit einer Innenverzahnung versehen ist. Dadurch sind die beiden Zahnräder 10 an den beiden Seiten der Schublade 3 drehfest miteinander verbunden.The stub axles 27 of the gears 10 protrude through the bearing body 7 and into a sleeve-shaped rod 11, which is provided at least in its two end regions with an internal toothing. As a result, the two gears 10 are rotatably connected to each other on the two sides of the drawer 3.

In jedem Lagerkörper 7 ist unterhalb des Zahnrades 10 ein Schieber 9 gelagert, der senkrecht zur Verfahrrichtung der Schublade 3 verschiebbar ist. Der Schieber 9 wird von einer Feder 8 beaufschlagt und zur Zahnstange 5 gedrückt.In each bearing body 7, a slider 9 is mounted below the gear 10, which is displaceable perpendicular to the direction of travel of the drawer 3. The slider 9 is acted upon by a spring 8 and pressed to the rack 5.

Jede Zahnstange 5 ist an ihrem freien Rand mit einer horizontalen Führungsleiste 14 versehen, die beim hinteren Ende der Zahnstange 5 mit Abstand vor einem Führungsklotz 29 endet. Der Führungsklotz 29 wird an seinem vorderen Ende von einer Schrägführung 15 begrenzt. Oberhalb der Führungsleiste 14 befindet sich eine vertikale Führungswand 30.Each rack 5 is provided at its free edge with a horizontal guide bar 14 which ends at the rear end of the rack 5 at a distance in front of a guide block 29. The guide block 29 is bounded at its front end by a slanted guide 15. Above the guide rail 14 is a vertical guide wall 30th

Die Zähne 17, 18 sind jeweils in einer Nut 31 der Zahnstange 5 angeordnet und werden von seitlichen Führungswänden begrenzt.The teeth 17, 18 are each arranged in a groove 31 of the rack 5 and are bounded by lateral guide walls.

Jede Zahnstange 5 ist an ihrem hinteren Ende mit einem Korrekturbereich 24 versehen, in dem die Höhe der Zähne 18 in etwa halb so groß ist als die Höhe der Zähne 17 im restlichen Laufbereich 25 der Zahnstange.Each rack 5 is provided at its rear end with a correction region 24 in which the height of the teeth 18 is approximately half the height of the teeth 17 in the remaining running region 25 of the rack.

Die Höhe der Zähne 18 beträgt maximal 3/4 der Höhe der Zähne 17 und liegt vorzugsweise in einem Bereich zwischen 2/3 und der Hälfte der Höhe der Zähne 17.The height of the teeth 18 is at most 3/4 of the height of the teeth 17 and is preferably in a range between 2/3 and half the height of the teeth 17th

Die Zahnstangen 5, die aus einem Kunststoffmaterial gefertigt sind, sind mittels Schrauben 16 an der Korpusseitenwand 1 angeschraubt, wobei die hinterste Schraube 16, d. h. der hinterste Befestigungspunkt der Zahnstange 5 an der Seitenwand 1 des Möbelkorpus sich im Abstand a vor dem hinteren Ende der Zahnstange 5 befindet.The racks 5, which are made of a plastic material, are screwed by means of screws 16 to the body side wall 1, wherein the rearmost screw 16, d. H. the rearmost attachment point of the rack 5 on the side wall 1 of the furniture body is located at a distance a in front of the rear end of the rack 5.

Wie insbesondere aus den Fig. 13a und 14 ersichtlich, ist der Abstand zwischen dem hinteren Ende der Zahnstange 5 und dem hintersten Befestigungspunkt größer als die Länge des Korrekturbereiches 24. Aufgrund der Elastizität der Zahnstange 5 kann sich das hintere Ende der Zahnstange 5 unter Druck elastisch nach unten durchbiegen, was in der Fig. 14a mit dem Bezugszeichen 21 gekennzeichnet ist.As in particular from the Fig. 13a and 14 can be seen, the distance between the rear end of the rack 5 and the rearmost attachment point is greater than the length of the correction region 24. Due to the elasticity of the rack 5, the rear end of the rack 5 can bend under pressure elastically downwards, which in the Fig. 14a designated by the reference numeral 21.

Beim Einschieben der Schublade 3 in den Möbelkorpus befinden sich die Zahnräder 10, wie in der Fig. 6 gezeigt, oberhalb der Zähne 17, 18 der Zahnstangen 5 und die Nasen der Schieber 9 oberhalb der Führungsleisten 14 der Zahnstangen 5. Der Schieber 9 stößt dabei mit seiner Spitze an der vertikalen Führungswand 30 der Zahnstange 5 an und wird gegen den Druck der Feder 8 in der Richtung der Schubladenmitte gedrückt. Zur Begrenzung des Schieberweges ist am Lagerkörper 7 ein Anschlag 13 vorgesehen. Damit der Lagerkörper 7 nicht zu weit nach oben gedrückt wird, weisen die Halterungen 6 Anschläge 12 auf, die den Verschiebeweg des Lagerkörpers 7 in der Vertikalen nach oben begrenzen.When inserting the drawer 3 in the furniture body are the gears 10, as in the Fig. 6 shown, above the teeth 17, 18 of the racks 5 and the lugs of the slide 9 above the guide rails 14 of the racks 5. The slider 9 abuts with its tip on the vertical guide wall 30 of the Rack 5 and is pressed against the pressure of the spring 8 in the direction of the middle of the drawer. To limit the slide path, a stop 13 is provided on the bearing body 7. So that the bearing body 7 is not pushed too far up, the holders 6 stops 12, which limit the displacement of the bearing body 7 in the vertical upward.

Die Schublade 3 wird so weit in den Möbelkorpus eingeschoben, bis die Schieber 9 an den Schrägführungen 15 der Zahnstangen 5 anstoßen. Bedingt durch die Schrägführungen 15 werden die Schieber 9 nach unten gedrückt und rasten unterhalb der Kante 32 der Klötze 29 ein, wobei sie von den Federn 8 unter die Zahnstangen 5 geschoben werden.The drawer 3 is inserted so far into the furniture body until the slide 9 abut the inclined guides 15 of the racks 5. Due to the inclined guides 15, the slide 9 are pressed down and engage below the edge 32 of the blocks 29, where they are pushed by the springs 8 under the racks 5.

Wird die Schublade 3 anschließend wieder geöffnet, d.h. aus dem Möbelkorpus herausgezogen, rutscht der Schieber 9 nicht durch die von der Schrägführung 15 und dem Ende der Führungsleiste 14 begrenzte Öffnung nach oben, sondern er rastet unterhalb der Führungsleiste 14 ein und wird unterhalb dieser geführt. Diese normale Betriebsstellung ist in den Fig. 5 und 9 gezeigt. In dieser Stellung der Schieber 9 wird ein Abheben der Zahnräder 10 von den Zähnen 17 der Zahnstangen 5 verhindert.If the drawer 3 is then reopened, ie pulled out of the furniture body, the slider 9 does not slip through the limited by the inclined guide 15 and the end of the guide rail 14 opening upwards, but he snaps below the guide rail 14 and is guided below this. This normal operating position is in the Fig. 5 and 9 shown. In this position, the slider 9, a lifting of the gears 10 is prevented by the teeth 17 of the racks 5.

Wurde die Schublade 3 gerade in den Möbelkorpus eingeschoben, so sind die Zähne der Zahnräder 10 korrekt wie bei einem üblichen Zahnstangengetriebe mit den Zähnen 17, 18 der Zahnstange im Eingriff. Diese Situation ist in den Fig. 13 und 13a gezeigt.When the drawer 3 has just been inserted into the furniture body, the teeth of the gears 10 are correctly engaged with the teeth 17, 18 of the rack as in a conventional rack and pinion gear. This situation is in the FIGS. 13 and 13a shown.

Kommt es jedoch zu einem Einspurfehler und somit zu einer Schrägstellung der Schublade 3, wie in der Fig. 12 gezeigt, wobei der Abstand 22 zwischen der Frontblende der Schublade 3 und der Seitenwand 1 an der rechten Seite der Schublade 3 wesentlich größer ist als an der linken Seite der Schublade 3, so ergibt sich zwangsläufig, dass das linke Zahnrad 10 das hintere Ende der Zahnstange 5 erreicht, bevor das rechte Zahnrad 10 das hintere Ende der Zahnstange 5 erreicht hat.However, if there is a Einspurfehler and thus to an inclination of the drawer 3, as in the Fig. 12 shown, wherein the distance 22 between the front panel of the drawer 3 and the side wall 1 on the right side of the drawer 3 is substantially larger than on the left side of the drawer 3, it follows inevitably that the left gear 10, the rear end of the rack 5 reached before the right gear 10 has reached the rear end of the rack 5.

Aufgrund des Korrekturbereiches 24 ist es möglich, die Stellung der Schublade 3 zu korrigieren. Diese Situation ist in der Fig. 14 gezeigt.Due to the correction area 24, it is possible to correct the position of the drawer 3. This situation is in the Fig. 14 shown.

Wird in diesem Fall die rechte Seite der Schublade 3 weiter in den Möbelkorpus hineingedrückt, dreht sich das Zahnrad 10 auf den oberen Abschlußflächen der Zähne 18, wobei das hintere Ende der Zahnstange 5 um das Maß 21 nach unten gedrückt und die Achse des Zahnrades 10 um das Maß 20 nach oben gedrückt wird. Das Zahnrad 10 kann somit über die Zähne 18 hinweggedreht werden, bis es in der hinteren Endstellung wiederum in Eingriff mit den Zähnen 18 gebracht wird (siehe Fig. 13a). Um das Abrollen der Zahnräder 10 im Korrekturbereich 24 zu erleichtern, ist die Zahnkopfbreite 33 der Zähne 18 größer als die Zahnkopfbreite 34 der Zähne 17.In this case, if the right side of the drawer 3 is pushed further into the furniture body, the gear 10 rotates on the upper end surfaces of the teeth 18, wherein the rear end of the rack 5 is pressed by the dimension 21 down and the axis of the gear 10 is pressed by the dimension 20 upwards. The gear 10 can thus be rotated over the teeth 18 until it is again brought into engagement with the teeth 18 in the rear end position (see Fig. 13a ). In order to facilitate the rolling of the gears 10 in the correction region 24, the tooth head width 33 of the teeth 18 is greater than the tooth head width 34 of the teeth 17th

Wird die Schublade wieder geöffnet, rollt das Zahnrad 10 normal mit den Zähnen 18, 17 kämmend am Zahnprofil der Zahnstange 5 ab.When the drawer is opened again, the toothed wheel 10 rolls in a normal manner with the teeth 18, 17, meshing with the tooth profile of the toothed rack 5.

Mit dem Bezugszeichen 19 ist die Eingriffsachse zwischen dem Zahnrad 10 und der Zahnstange 5 gekennzeichnet.The reference numeral 19, the engagement axis between the gear 10 and the rack 5 is marked.

In den Ausführungsbeispielen nach den Fig. 15 bis 25 befindet sich im Korrekturbereich ein bewegbarer Zahn 50. Dieser bewegbare Zahn 50 ist entweder, wie in den Fig. 17 bis 22 gezeigt, auf einer Achse 23 kippbar bzw. drehbar gelagert oder, wie im Ausführungsbeispiel nach den Fig. 23 bis 24 gezeigt, linear verschiebbar.In the embodiments of the FIGS. 15 to 25 is located in the correction area a movable tooth 50. This movable tooth 50 is either, as in the Fig. 17 to 22nd shown tiltable or rotatably mounted on an axis 23 or, as in the embodiment of the Fig. 23 to 24 shown, linearly displaceable.

Die Fig. 25 zeigt eine Variante der kippbaren Lagerung, wobei der Zahn 50 dem Zahnrad 10 seitlich ausweichen kann. In allen Ausführungsbeispielen ist der Abstand zwischen dem Zahn 50 und dem nächsten starren Zahn 17 der Zahnstange 5 in etwa doppelt so groß als der Abstand zwischen zwei benachbarten starren Zähnen 17.The Fig. 25 shows a variant of the tiltable mounting, wherein the tooth 50 can escape the gear 10 side. In all embodiments, the distance between the tooth 50 and the next rigid tooth 17 of the rack 5 is about twice as large as the distance between two adjacent rigid teeth 17th

Gemeinsam ist allen Ausführungsbeispielen, dass der bewegbare Zahn 50 nur in einer Richtung ausweichen kann, d.h. im Ausführungsbeispiel nach den Fig. 17 bis 24 kann der Zahn 50 jeweils nur in der Richtung zum hintersten festen Zahn 17 der Zahnstange 5 bewegt werden. Im Ausführungsbeispiel nach der Fig. 25 kann der Hebel 35, an dessen freien Ende der Zahn 50 ausgebildet ist, nur in der Richtung des Pfeiles ausschwenken.Common to all embodiments that the movable tooth 50 can only escape in one direction, ie in the embodiment of the Fig. 17 to 24 For example, the tooth 50 can be moved only in the direction of the rearmost fixed tooth 17 of the rack 5. In the embodiment of the Fig. 25 For example, the lever 35, at the free end of which the tooth 50 is formed, can swing out only in the direction of the arrow.

Beim Einschieben der Schublade 3 in den Möbelkorpus kämmen die Zahnräder 10 mit den Zähnen 17 der Zahnstangen 5. In der hintersten Stellung der Schublade umfassen je zwei Zähne 10' eines Zahnrades 10 den bewegbaren Zahn 50 der jeweiligen Zahnstange 5.When inserting the drawer 3 in the furniture carcass mesh the gears 10 with the teeth 17 of the racks 5. In the rearmost position of the drawer each include two teeth 10 'of a gear 10, the movable tooth 50 of the respective rack fifth

Wurde die Schublade 3 gerade in den Möbelkorpus eingeschoben, so sind die Zähne 10' der Zahnräder 10 korrekt wie bei einem üblichen Zahnstangengetriebe mit den Zähnen 17 der Zahnstange 5 im Eingriff.If the drawer 3 has just been inserted into the furniture carcass, then the teeth 10 'of the gears 10 are correctly engaged with the teeth 17 of the rack 5, as in a conventional rack gear.

Kommt es jedoch zu einem Einspurfehler und somit zu einer Schrägstellung der Schublade 3, wie in der Fig. 12 gezeigt, wobei der Abstand 22 zwischen der Frontblende der Schublade 3 und der Seitenwand 1 an der rechten Seite der Schublade 3 wesentlich größer ist als an der linken Seite der Schublade 3, so ergibt sich zwangsläufig, dass das linke Zahnrad 10 das hintere Ende der Zahnstange 5 erreicht, bevor das rechte Zahnrad 10 das hintere Ende der Zahnstange 5 erreicht hat.However, if there is a Einspurfehler and thus to an inclination of the drawer 3, as in the Fig. 12 shown, wherein the distance 22 between the front panel of the drawer 3 and the side wall 1 on the right side of the drawer 3 is substantially larger than on the left side of the drawer 3, it follows inevitably that the left gear 10, the rear end of the rack 5 reached before the right gear 10 has reached the rear end of the rack 5.

Aufgrund des bewegbaren Zahnes 50 auf der linken Seite ist es nun möglich, die Stellung der Schublade 3 zu korrigieren. Diese Situation ist in den Fig. 22 und 24 gezeigt.Due to the movable tooth 50 on the left side, it is now possible to correct the position of the drawer 3. This situation is in the Fig. 22 and 24 shown.

Wird in diesem Fall die rechte Seite der Schublade 3 weiter in den Möbelkorpus hineingedrückt, dreht sich das Zahnrad 10 auf der linken Seite auf der Stelle. Dabei wird im Ausführungsbeispiel nach den Fig. 17 bis 22 der bewegbare Zahn 50 nach vorne gekippt.In this case, when the right side of the drawer 3 is pushed further into the furniture body, the gear 10 on the left side rotates on the spot. It is in the embodiment of the Fig. 17 to 22nd the movable tooth 50 tilted forward.

Das Zahnrad 10 auf der linken Seite kann sich so lange drehen, bis das Zahnrad 10 auf der rechten Seite der Schublade 3 die hinterste Stellung erreicht hat. Nun ist die Schublade 3 gerade ausgerichtet und kann gerade geführt aus dem Möbelkorpus herausgezogen werden.The left side gear 10 may rotate until the gear 10 on the right side of the drawer 3 has reached the rearmost position. Now the drawer 3 is straight and can be pulled straight out of the furniture carcass.

Der auf der Achse 23 kippbar gelagerte Zahn 50 ist mit einem seitlich vertikal abstehenden Arm 36 versehen, auf den eine Feder 37 drückt. Die Feder 37 drückt den Zahn 50 in die vertikale Stellung.The tiltably mounted on the axis 23 tooth 50 is provided with a laterally vertically projecting arm 36, on which a spring 37 presses. The spring 37 pushes the tooth 50 in the vertical position.

Es ist ein Anschlag vorgesehen, sodass der Zahn 50 nur in der Richtung zu den feststehenden Zähnen 17 gekippt werden kann. Dadurch ist eine Drehung des Zahnrades 10 in der Richtung des Pfeiles A der Fig. 22 möglich. Eine Drehung des Zahnrades 10 in der Richtung des Pfeiles B der Fig. 21 wird durch diesen Anschlag bei feststehender Schublade 3 verhindert. Das Zahnrad 10 kann erst dann in der Richtung des Pfeiles B gedreht werden, wenn die Schublade 3 aus dem Möbelkorpus herausfährt.A stopper is provided so that the tooth 50 can only be tilted in the direction of the fixed teeth 17. Thereby, a rotation of the gear 10 in the direction of arrow A of Fig. 22 possible. A rotation of the gear 10 in the direction of arrow B of Fig. 21 is prevented by this stop at a fixed drawer 3. The gear 10 can only then in the direction of the arrow B are rotated when the drawer 3 moves out of the furniture body.

Im Ausführungsbeispiel nach den Fig. 23 und 24 ist der bewegbare Zahn 50 auf einem verschiebbaren Klotz 38 ausgebildet, der in einer Aussparung 42 der Zahnstange 5 verfahrbar ist. Der Klotz 38 ist linear in der Richtung der Zahnstange 5 verschiebbar und wird von einer Feder 37, die dieses Mal eine Schraubendruckfeder ist, nach hinten gedrückt.In the embodiment of the FIGS. 23 and 24 the movable tooth 50 is formed on a displaceable block 38, which is movable in a recess 42 of the rack 5. The pad 38 is linearly displaceable in the direction of the rack 5 and is urged rearward by a spring 37 which is a helical compression spring this time.

Wurde die Schublade 3 schräg in den Möbelkorpus eingefahren, so kann sich das hintere Zahnrad 10 auf der Stelle in der Richtung des Pfeiles A der Fig. 24 drehen. Dabei wird der Klotz 38 mit dem Zahn 50 entgegen dem Druck der Feder 37 nach vorne verschoben.If the drawer 3 is moved obliquely into the furniture body, then the rear gear 10 can be in place in the direction of arrow A of Fig. 24 rotate. In this case, the block 38 is moved with the tooth 50 against the pressure of the spring 37 to the front.

In der Gegenrichtung ist das Zahnrad 10 gesperrt, d.h. der Klotz 38 mit dem Zahn 50 kann nicht weiter nach links verfahren werden, als es in der Fig. 23 gezeigt ist.In the opposite direction, the gear 10 is locked, ie the block 38 with the tooth 50 can not be moved to the left, as it is in the Fig. 23 is shown.

Im Ausführungsbeispiel nach der Fig. 25 ist der Zahn 50 auf einem Arm 35 ausgebildet, der um eine Achse 39 drehbar ist.In the embodiment of the Fig. 25 the tooth 50 is formed on an arm 35 which is rotatable about an axis 39.

Der Zahn 50 ist mit einer vertikalen Schrägfläche 40 versehen.The tooth 50 is provided with a vertical inclined surface 40.

Drückt der Zahn 10' des Zahnrades 10, das sich in seiner hintersten Position befindet, bei der Drehung des Zahnrades 10 auf die Schrägfläche 40, so kann der bewegbare Zahn 50 der Zahnstange 5 gegen den Druck der Feder 37 in der Richtung des Pfeiles A der Fig. 25 ausweichen und das Zahnrad 10 kann sich drehen.Presses the tooth 10 'of the gear 10, which is in its rearmost position, upon rotation of the gear 10 on the inclined surface 40, the movable tooth 50 of the rack 5 against the pressure of the spring 37 in the direction of arrow A of Fig. 25 Dodge and the gear 10 can rotate.

Es ist ein Anschlag 41 vorgesehen, der ein Ausweichen des Zahnes 50 in der Gegenrichtung unmöglich macht und daher das Zahnrad 10 in dieser Drehrichtung sperrt.There is a stop 41 is provided, which makes it impossible to escape the tooth 50 in the opposite direction and therefore blocks the gear 10 in this direction of rotation.
