Description

Die Erfindung betrifft einen Anhänger für ein Kinderfahrzeug. Bei dem Kinderfahrzeug kann es sich um ein Tretfahrzeug wie zum Beispiel einen mit einer Tretkurbel versehenen Traktor handeln, oder aber um ein mit einem Motor versehenes Kinderfahrzeug.The invention relates to a trailer for a children's vehicle. The child vehicle may be a pedal vehicle, such as a cranked tractor, or a child-mounted vehicle equipped with an engine.

Die US 2006/011393 A1 offenbart einen Anhänger für ein Kinderfahrzeug, der eine Wanne enthält, in der Gegenstände transportiert werden können.The US 2006/011393 A1 discloses a trailer for a children's vehicle containing a tub in which objects can be transported.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Anhänger für ein Kinderfahrzeug anzugeben, der für Kinder einen hohen Spielwert hat.The present invention has for its object to provide a trailer for a children's vehicle, which has a high play value for children.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments of the invention are characterized in the subclaims.

Der erfindungsgemäße Anhänger hat eine Wanne zur Aufnahme von Streugut, wie zum Beispiel Sand oder Granulat mit einer nicht zu groben Körnung. Die Wanne liegt auf einem Antriebsgehäuse auf, in der eine Antriebsachse des Anhängers drehbar gelagert ist, die drehfest mit wenigstens einem der beiden auf der Achse sitzenden Räder verbunden ist. Die Antriebsachse wird somit gedreht, wenn der Anhänger von einem Kinderfahrzeug gezogen wird.The trailer according to the invention has a tray for receiving grit, such as sand or granules with a not too coarse grain. The tub rests on a drive housing, in which a drive axle of the trailer is rotatably mounted, which is rotatably connected to at least one of the two wheels sitting on the axle. The drive axle is thus rotated when the trailer is pulled by a child's vehicle.

Etwa mittig zwischen den Rädern des Anhängers sitzt auf der Antriebsachse ein Antriebsrad, vorzugsweise ein Antriebszahnrad, das mit der Antriebsachse drehfest verbunden ist. Dieses bevorzugt vorgesehene Antriebszahnrad kämmt mit einem aus vorzugsweise 5 Zahnrädern bestehenden Zahnradgetriebe, dessen Zahnräder in dem Antriebsgehäuse angeordnet sind. Außerdem ist erfindungsgemäß ein Streuteller vorgesehen, der vorzugsweise aus einer ebenen, horizontal angeordneten kreisförmigen Scheibe besteht, auf deren Oberseite sternförmig Rippen angebracht sind, wobei der Streuteller drehbar mit dem Abtriebszahnrad des Zahnradgetriebes gekoppelt ist.Approximately centrally between the wheels of the trailer sits on the drive axle, a drive wheel, preferably a drive gear, which is rotatably connected to the drive shaft. This preferably provided drive gear meshes with a gear consisting preferably of five gears, the gears are arranged in the drive housing. In addition, a scattering plate is provided according to the invention, which preferably consists of a flat, horizontally arranged circular disc, mounted on the top of star-shaped ribs are, wherein the spreading plate is rotatably coupled to the output gear of the gear transmission.

De r Streuteller kann auch auf andere Weise mit der Antriebswelle gekoppelt sein, bei spielsweise über einen Ketten- oder Riemenantrieb.De r spreading plate can be coupled in other ways with the drive shaft, for example, a chain or belt drive.

Um eine mögliche Verletzungsgefahr und eine Beschädigung des Streumechanismus zu vermeiden, wenn der Streuteller bei sich drehendem Abtriebszahnrad blockiert wird, ist ein Ratschenmechanismus vorgesehen, durch den der Streuteller von dem Abtriebszahnrad entkoppelbar ist.In order to avoid a possible risk of injury and damage to the scattering mechanism, when the spreader plate is blocked when the driven gear rotates, a ratchet mechanism is provided by which the spitter plate is decoupled from the output gear.

Die Wanne des Anhängers hat einen Boden mit einer Austrittsöffnung für das Streugut, die über dem Streuteller angeordnet ist, so dass austretendes Streugut auf den Streuteller fällt.The tub of the trailer has a bottom with a discharge opening for the spreading material, which is arranged above the spreading plate, so that escaping spreading material falls onto the spreading plate.

Mit dem erfindungsgemäßen Anhänger kann ein Kind im Winter beispielsweise einen von Schnee geräumten, jedoch eisig glatten Zugang zu einer Haustür oder einen Gehweg entlang eines Grundstücks gegen Rutschgefahr sichern, in dem es Streugut aus der Wanne des Anhängers austreten lässt und über die mit dem Kinderfahrzeug abgefahrene Fläche verteilt. Diese spielerische Beschäftigung ist nicht nur für Kinder interessant und mit einem hohen Spielwert verbunden, sondern bei entsprechenden Witterungsverhäftnissen auch sehr nützlich.With the trailer according to the invention, a child can protect in the winter, for example, a snow-cleared, but icy smooth access to a front door or walkway along a plot against slipping, in which it can leak grit from the tub of the trailer and on the abused with the children's vehicle Distributed area. This playful activity is not only interesting for children and associated with a high play value, but also very useful in appropriate weather conditions.

Die Wanne des Anhängers besteht vorzugsweise aus Kunststoff und ist bevorzugt im Spritzgussverfahren hergestellt. Der Boden der Wanne fällt in der Gebrauchslage des Anhängers auf einer horizontalen Fläche zu der Austrittsöffnung hin ab, so dass bei der Abgabe von Streugut stets Sand oder dergleichen zu der Austrittsöffnung hin selbst tätig nachrutscht.The tub of the trailer is preferably made of plastic and is preferably produced by injection molding. The bottom of the tub drops in the position of use of the trailer on a horizontal surface to the outlet opening from, so that when discharging grit always sand or the like to the outlet opening itself slipping.

Mit großem Vorteil ist vorgesehen, dass ein Schieber unter der Wanne hin und her beweglich geführt ist, der die Austrittsöffnung verschließen oder freigeben kann. Der Schieber ist mit einem Griffabschnitt versehen, der an der Deichsel-Seite des Anhängers frei liegt, so dass er von einem auf dem Kinderfahrzeug sitzenden Kind bequem greifbar ist, um die Austrittsöffnung der Wanne zu verschließen oder freizugeben, wobei mit einer ausgewählten Öffnungsstellung die abgegebene Streugutmenge eingestellt werden kann.With great advantage, it is provided that a slide is guided under the pan to and fro, which can close or release the outlet opening. The slider is provided with a handle portion which is exposed on the drawbar side of the trailer, so that it is easily accessible by a child sitting on the child car to close the outlet opening of the tub or be released, with a selected opening position, the delivered amount of grit can be adjusted.

Die Wanne ist mit einem abnehmbaren oder aufklappbaren Deckel versehen, was den Vorteil hat, dass bei auftretendem Niederschlag das Streugut in der Wanne trocken bleibt und damit nicht verklumpt.The tub is provided with a removable or hinged lid, which has the advantage that when any precipitation occurs, the grit remains dry in the tub and thus does not clump.

Über der Austrittsöffnung der Wanne können voneinander beabstandete Rippen angeordnet bzw. angeformt sein, die eine Art Sieb bilden, wodurch die Korngröße des aus der Austrittsöffnung fallenden Streuguts begrenzt wird. Der freie Abstand zwischen den Rippen beträgt vorteilhafterweise etwa 5 bis 10 mm. Durch dieses Sieb, das beispielsweise auch maschenartig ausgebildet sein kann, wird verhindert, dass der darunter angeordnete Streuteller durch zu groben Kies oder dergleichen blockiert werden kann.About the outlet opening of the trough spaced fins may be arranged or formed, which form a kind of sieve, whereby the grain size of the falling out of the outlet grit is limited. The free distance between the ribs is advantageously about 5 to 10 mm. Through this sieve, which may be formed, for example, mesh-like, it is prevented that the scattering plate arranged underneath can be blocked by coarse gravel or the like.

Das Antriebsgehäuse, auf dem die Wanne aufliegt, ist vorteilhafterweise aus einem unteren Gehäuseteil, der feststehende vertikale Achsen zur Lagerung der Zahnräder des bevorzugt vorgesehenen Zahnradgetriebes aufweisen kann, einer oberen Abdeckung des unteren Gehäuseteils und einem darüber angeordneten oberen Gehäuseteil zusammengesetzt, wobei in dem oberen Gehäuseteil die Antriebsachse des Anhängers drehbar gelagert ist. Die einzelnen Teile des Antriebsgehäuses können miteinander verrastet und/oder verschraubt sein.The drive housing, on which rests the tub, is advantageously composed of a lower housing part, which may have fixed vertical axes for supporting the gears of the preferred gear mechanism provided, an upper cover of the lower housing part and an upper housing part arranged above, wherein in the upper housing part the drive axle of the trailer is rotatably mounted. The individual parts of the drive housing can be locked together and / or screwed.

Der Streuteller befindet sich zweckmäßigerweise über der Abdeckung und unter einer oberen horizontalen Wand des oberen Gehäuseteils, die mit einer etwa halbkreisförmigen Kontur den Streuteller überdeckt und eine Aussparung für das Streugut aufweist, die mit der Austrittsöffnung der Wanne fluchtet. Der (in der horizontalen Gebrauchslage des Anhängers) bevorzugt horizontale Streuteller ist mit einer vertikalen Achse verbunden, die mit dem Abtriebszahnrad des Zahnradgetriebes gekoppelt ist.The spreading plate is expediently above the cover and below an upper horizontal wall of the upper housing part, which covers the spreading plate with an approximately semicircular contour and has a recess for the spreading material, which is aligned with the outlet opening of the trough. The (in the horizontal position of use of the trailer) preferably horizontal spreading plate is connected to a vertical axis which is coupled to the output gear of the gear transmission.

Wenn der Anhänger von dem Kinderfahrzeug gezogen wird, überträgt sich die Drehung der mit einem Rad oder beiden Rädern des Anhängers drehfest verbundenen Antriebsachse auf das Getriebe und von dort auf den Streuteller, wodurch das darauf fallende Streugut radial weggeschleudert wird. Damit dies nur zu de rn rückwärtigen Bereich des Anhängers hin erfolgt, hat der obere Gehäuseteil eine nach unten abgewinkelte Umfangswand, die den Drehteller zur Vorderseite, das heißt in Richtung der Deichsel hin abdeckt und zur Rückseite der Wanne hin freilässt, indem ein Spalt zwischen der Umfangswand und dem Streuteller offen bleibt. Nach vorne hin prallt das Streugut gegen die den Streuteller mit minimalen Abstand umfassende Umfangswand und bleibt nahezu vollständig auf dem Streuteller liegen, bis dieser sich weitergedreht hat.When the trailer is pulled by the child's vehicle, the rotation of the one or both wheels of the trailer rotatably connected drive shaft transmits to the transmission and from there to the spreading plate, whereby the falling thereon grit is thrown radially. To make this happen only to the rear area of the trailer, the upper housing part has a downwardly angled peripheral wall which covers the turntable to the front, ie in the direction of the drawbar towards the back of the trough down by a gap between the Circumferential wall and the spreading plate remains open. Towards the front, the spreading material bounces against the peripheral wall surrounding the spreading plate with minimal spacing and remains almost completely on the spreading plate until it has turned further.

Die Wanne ist mit dem bevorzugt ebenfalls aus Kunststoff bestehenden Antriebsgehäuse zweckmäßigerweise verrastet und/oder verschraubt. Dabei liegt die Wanne auf seitlich von dem Antriebsgehäuse abstehenden Auflagern stabil auf.The trough is expediently locked and / or screwed to the preferably also made of plastic drive housing. In this case, the trough is stable on laterally projecting from the drive housing supports.

Weiter wird vorgeschlagen, dass unter der Wanne zwei voneinander beabstandete U-förmige Stege angeordnet sind, in die entsprechend geformte Arme einer Deichsel vorzugsweise formschlüssig eingesetzt sind.It is also proposed that two spaced-apart U-shaped webs are arranged under the tub, are preferably inserted positively in the correspondingly shaped arms of a drawbar.

Zwischen den zwei U-förmigen Stegen sollte eine ebene Querwand im Abstand von dem Boden der Wanne verlaufen, auf der der Schieber aufliegt, der zwischen den U-förmigen Stegen und in Aussparungen bzw. Schlitzen des Antriebsgehäuses geführt ist.Between the two U-shaped webs should be a flat transverse wall at a distance from the bottom of the trough, on which the slide rests, which is guided between the U-shaped webs and in recesses or slots of the drive housing.

Auch die beiden Räder des Anhängers, die Zahnräder, die Deichsel und der Schieber sind vorzugsweise aus Kunststoff hergestellt, ohne dass die Erfindung hierauf beschränkt ist.The two wheels of the trailer, the gears, the drawbar and the slide are preferably made of plastic, without the invention being limited thereto.

Der in den Figuren 1A - 1E in verschiedenen Ansichten dargestellte Anhänger hat zwei Räder 1, die auf einer Antriebsachse 2 sitzen, wobei wenigstens ein Rad 1 drehfest mit der Antriebsachse 2 verbunden ist. Die Achse 2 ist drehbar in einem Antriebsgehäuse 3 gelagert, auf dem eine Wanne 4 befestigt ist. Die Wanne 4 hat einen schräg zur Rückseite des Anhängers abfallenden Boden 5 und ist an ihrer Oberseite durch einen abnehmbaren Deckel 6 geschlossen.The in the Figures 1A - 1E shown in different views trailer has two wheels 1, sitting on a drive axle 2, wherein at least one wheel 1 rotatably connected to the drive axle 2 is connected. The axis 2 is rotatably mounted in a drive housing 3, on which a trough 4 is attached. The tub 4 has a sloping to the rear of the trailer floor 5 and is closed at its top by a removable cover 6.

Die Wanne 4 ist mit einer Deichsel 7 verbunden, die an ein nicht dargestelltes Kinderfahrzeug ankoppelbar ist. Die Deichsel 7 hat zwei seitlich beabstandete, im wesentlichen kubisch geformte Arme 8, die in zwei U-förmige Stege 9 eingesetzt sind, die am Boden 5 der Wanne 4 angebracht sind.The tub 4 is connected to a drawbar 7, which can be coupled to a child vehicle, not shown. The drawbar 7 has two laterally spaced, substantially cubic shaped arms 8 which are inserted into two U-shaped webs 9, which are attached to the bottom 5 of the tub 4.

Zwischen den beiden Armen 8 der Deichsel 7 ist ein Schieber 10 dicht unter dem Boden 5 der Wanne 4 angeordnet, der mit einem abgewinkelten Handgriff 11 versehen ist, der von einem auf einem Fahrzeug sitzenden Kind bequem ergriffen und hin und her bewegbar gelagert ist. Zwischen den U-förmigen Stegen 9 ist im Abstand unter dem Boden 5 der Wanne 4 eine Querwand 12 angeformt, auf der der Schieber 10 aufliegt.Between the two arms 8 of the drawbar 7, a slider 10 is arranged closely below the bottom 5 of the tub 4, which is provided with an angled handle 11, which is comfortably gripped by a child sitting on a vehicle and mounted to move back and forth. Between the U-shaped webs 9, a transverse wall 12 is integrally formed at a distance below the bottom 5 of the trough 4, on which the slide 10 rests.

Wie die Figuren 2 und 3 zeigen, enthält der Boden 5 an seinem hinteren Rand eine Austrittsöffnung 13 für in die Wanne 4 aufgenommenes Streugut (nicht dargestellt). Die Austrittsöffnung 13 ist von parallelen Rippen 14 überdeckt, die einen Abstand von etwa 10 mm voneinander haben und als Sieb für das austretende Streugut dienen.As the Figures 2 and 3 show the bottom 5 at its rear edge an outlet opening 13 for received in the tub 4 grit (not shown). The outlet opening 13 is covered by parallel ribs 14, which have a distance of about 10 mm from each other and serve as a sieve for the exiting grit.

Der Schieber 10 hat eine solche Erstreckung, dass sein von dem Handgriff 11 abgewandter Endabschnitt 15 dicht unter der Austrittsöffnung positioniert ist und diese verschließt, wenn sich der Schieber 10 in der eingeschobenen Endposition befindet. Wenn der Schieber 10 an seinem Handgriff 11 in Richtung der Deichsel 7 gezogen wird, wird die Austrittsöffnung 13 zunehmend freigegeben.The slider 10 has such an extent that its end portion 15 facing away from the handle 11 is positioned closely below the outlet opening and closes it when the slider 10 is in the inserted end position. When the slider 10 is pulled on its handle 11 in the direction of the drawbar 7, the outlet opening 13 is increasingly released.

Aus Figur 2 ist zu ersehen, dass auf der Antriebsachse 2 ein Kegelzahnrad 16 etwa in der Mitte der Antriebsachse 2 sitzt, das drehfest mit der Antriebsachse 2 verbunden ist. Das Kegelzahnrad kämmt mit einem Kegelzahnrad 17 eines Zahnradgetriebes, das noch vier weitere miteinander kämmende Zahnräder 18 enthält, um ein Zahnradgetriebe zu bilden, mit dem eine Streuscheibe 19 gedreht werden kann. Die Zahnräder 17, 18 sind in einem unteren Gehäuseteil 20 angeordnet, das zur Lagerung der Zahnräder vertikale Achsstummel 21 hat.Out FIG. 2 It can be seen that on the drive axle 2, a bevel gear 16 is seated approximately in the middle of the drive axle 2, which is rotatably connected to the drive axle 2. The bevel gear meshes with a bevel gear 17 of a gear transmission, which includes four more intermeshing gears 18 to form a gear mechanism with which a lens 19 can be rotated. The gears 17, 18 are arranged in a lower housing part 20, which has vertical stub axles 21 for mounting the gears.

Die Zahnräder sind von einer Abdeckung 22 des unteren Gehäuseteils 20 überdeckt, die eine Aussparung 23 enthält, durch die das Kegelzahnrad 16 in Eingriff mit dem Kegelzahnrad 17 gelangt. Die Abdeckung 22 hat einen etwa halbkreisförmigen Abschnitt 24 mit einem kurzen Rohrabschnitt 25, durch den hindurch eine Achse der darauf angeordneten Streuscheibe 19 mit dem Abtriebszahnrad 18a gekoppelt ist.The gears are covered by a cover 22 of the lower housing part 20, which includes a recess 23 through which the bevel gear 16 comes into engagement with the bevel gear 17. The cover 22 has an approximately semicircular portion 24 with a short tube portion 25 through which an axis of the lens 19 disposed thereon is coupled to the output gear 18a.

Diese Achse ist durch einen rohrförmigen Ansatz 40 gebildet, der drehfest an der Streuscheibe 19 angebracht oder angeformt ist und sich von der Streuscheibe 19 nach oben und unten erstreckt. Am unteren Endabschnitt des rohrförmigen Ansatzes 40 sind Zähne 41 mit schrägen Flanken ausgebildet, die in entsprechende Zähne 42 eingreifen, die an der Oberseite des Abtriebszahnrades 18a angeformt sind. Der sich nach oben erstreckende Teil des rohrförmigen Ansatzes 40 verjüngt sich zu einem Rohrabschnitt 43, in den eine Schraubenfeder 44 eingesetzt ist, die sich mit ihrem unteren Ende in dem Rohrabschnitt abstützt und über die Randkante 45 des Rohrabschnitts 43 hinaus vorsteht.This axis is formed by a tubular projection 40 which is rotatably mounted or formed on the lens 19 and extends from the lens 19 up and down. At the lower end portion of the tubular projection 40 teeth 41 are formed with oblique edges which engage in corresponding teeth 42 which are integrally formed on the upper side of the driven gear 18a. The upwardly extending portion of the tubular extension 40 tapers to a tubular portion 43 into which a coil spring 44 is inserted, which is supported at its lower end in the tubular portion and projects beyond the peripheral edge 45 of the tubular portion 43.

Die Streuscheibe 19 ist mit dem unteren Teil des rohrförmigen Ansatzes 40 in dem Rohrabschnitt 25 der Abdeckung 22 geführt, und die Feder 44 stützt sich an der Unterseite der Wand 30 des oberen Gehäuseteils 27 ab, wobei zwischen der Randkante 45 des Rohrabschnitts 43 und der Wand 30 des Gehäuseteils 27 ein Abstand verbleibt, der größer als die Höhe h der Zähne 41 und 42 ist. Damit ist ein Ratschenmechanismus gebildet, der es ermöglicht, die Streuscheibe 19 antriebsmäßig von dem sich drehenden Abtriebszahnrad 18a zu trennen, wenn dieses beispielsweise durch einen Finger einer Spielperson oder durch zu großkörniges Streugut blockiert wird, wobei in diesem Fall die Zähne 41 an den schrägen Flanken der Zähne 42 gegen Federkraft nach oben gleiten. Hierdurch ist eine mögliche Verletzungsgefahr und eine Beschädigung des Streumechanismus vermieden.The diffuser 19 is guided with the lower part of the tubular extension 40 in the pipe section 25 of the cover 22, and the spring 44 is supported on the underside of the wall 30 of the upper housing part 27, wherein between the peripheral edge 45 of the pipe section 43 and the wall 30 of the housing part 27 a Distance remains greater than the height h of the teeth 41 and 42 is. Thus, a ratchet mechanism is formed which allows the lens 19 to drively separate from the rotating driven gear 18a when it is blocked, for example, by a playperson's finger or excessive grit, in which case the teeth 41 on the sloping flanks the teeth 42 slide against spring force upwards. As a result, a possible risk of injury and damage to the scattering mechanism is avoided.

Der Rohrabschnitt 43 kann in einem rohrförmigen unteren Ansatz des oberen Gehäuseteils 27 geführt sein.The pipe section 43 may be guided in a tubular lower extension of the upper housing part 27.

Auf der Oberseite der Streuscheibe 19 sind sechs im wesentlichen sternförmig angeordnete, leicht gebogene Rippen 26 angeformt, die bis an den rohrförmigen Ansatz 40 reichen. An der Unterseite der Streuscheibe 19 sind drei kurze Rippen 46 angeformt, die verhindern, dass sich auf dem halbkreisförmigen Abschnitt 24 Streugut ansammelt und die Streuscheibe 19 blockiert.On the upper side of the lens 19, six substantially star-shaped, slightly curved ribs 26 are formed, which extend to the tubular extension 40. On the underside of the lens 19 three short ribs 46 are formed, which prevent accumulates on the semicircular portion 24 scattering and blocks the lens 19.

Der untere Gehäuseteil 20 und die Abdeckung 22 sind an einem oberen Gehäuseteil 27 befestigt, vorzugsweise angeschraubt. In hülsenförmigen Abschnitten 28 des oberen Gehäuseteils 27 ist die Antriebsachse 2 drehbar gelagert. Der obere Gehäuseteil 27 hat seitlich abstehende, schräg nach oben weisende Auflager 29 für die auf der Oberseite des oberen Gehäuseteils 27 aufliegende Wanne 4, die zudem mit dem oberen Gehäuseteil 27 verschraubt und/oder verrastet ist. Das obere Gehäuseteil 27 hat eine obere Wand 30 mit einer etwa halbkreisförmigen Kontur 31, die die Streuscheibe 19 überdeckt. In der oberen Wand 30 ist eine Öffnung 32 ausgebildet, die mit der Austrittsöffnung 13 in dem Wannenboden 5 fluchtet, so dass austretendes Streugut durch die Öffnung 32 auf den darunter angeordneten Streuteller 19 fällt. Die Wand 30 hat eine nach unten abgewinkelte Umfangswand 33 und 34. Der Wandabschnitt 33 endet in einem Abstand über der Streuscheibe 19, so dass Streugut zur Rückseite des Anhängers hin weggeschleudert werden kann. Die Umfangswand 34 erstreckt sich weiter nach unten. Wie Figur 2 zeigt, verläuft eine innere Umfangswand 35 etwa um die vordere Hälfte der Streuscheibe 19 und verhindert, dass Streugut in dieser Richtung von der Streuscheibe 19 weggeschleudert wird. Hierzu hat die Umfangswand 35 einen nur minimalen Abstand vom Rand der Streuscheibe 19.The lower housing part 20 and the cover 22 are attached to an upper housing part 27, preferably screwed. In sleeve-shaped sections 28 of the upper housing part 27, the drive axle 2 is rotatably mounted. The upper housing part 27 has laterally projecting, obliquely upward bearing 29 for the resting on the top of the upper housing part 27 trough 4, which is also bolted to the upper housing part 27 and / or locked. The upper housing part 27 has an upper wall 30 with an approximately semicircular contour 31, which covers the lens 19. In the upper wall 30, an opening 32 is formed, which is aligned with the outlet opening 13 in the tub bottom 5, so that escaping spreading material through the opening 32 on the scattering plate 19 arranged underneath falls. The wall 30 has a downwardly angled peripheral wall 33 and 34. The wall portion 33 terminates at a distance above the lens 19, so that grit can be thrown back to the back of the trailer. The peripheral wall 34 extends further down. As FIG. 2 shows, an inner peripheral wall 35 extends approximately to the front half of the lens 19 and prevents grit in this direction from the lens 19th is thrown away. For this purpose, the peripheral wall 35 has only a minimal distance from the edge of the lens 19th

Der Schieber 10 ist mit abgewinkelten Seitenwänden 36 in Schlitzen 37 in der vorderen Stirnwand 38 und an Führungsflächen 39 an der Oberseite des oberen Gehäuseteils 27 geführt.The slider 10 is guided with angled side walls 36 in slots 37 in the front end wall 38 and on guide surfaces 39 at the top of the upper housing part 27.

Es wird betont, dass die Erfindung nicht auf die beschriebenen und dargestellten Ausführungsformen beschränkt ist. Vielmehr sind alle offenbarten Merkmale der Ausführungsformen auch einzeln untereinander anders als oben beschrieben miteinander kombinierbar.It is emphasized that the invention is not limited to the described and illustrated embodiments. Rather, all disclosed features of the embodiments are individually combined with each other differently than described above.
