Abstract

Es wird ein neues Aufrührorgan (9), insbesondere für Lackstifte zur Ausbesserung von Lackschäden an Kraftfahrzeugen beschrieben, das in der Art eines Gebläselaufrades mit auf dem Umfang vorgesehenen, zur Achsrichtung angestellten Schaufeln (12) versehen ist. Dieses Aufrührorgan umgibt mit einem rohrförmigen Innenteil (10) den Pinsel (6) des Lackstiftes und kann durch axiales Schütteln des Behälters die Lackflüssigkeit in eine rotierende Mischbewegung versetzen.A new stirring element (9), in particular for touch-up pencils for repairing damage to the paintwork on motor vehicles, is described, which is provided in the manner of a blower impeller with blades (12) provided on the circumference and oriented towards the axial direction. This stirring element surrounds the brush (6) of the paint pen with a tubular inner part (10) and can cause the paint liquid to rotate in a rotating mixing movement by axially shaking the container.

Description

Die Erfindung betrifft ein Aufrührorgan für mit Farben o.dgl. gefüllte zylindrische Behälter, insbesondere für Lackstifte zur Ausbesserung von Lackschäden an Kraftfahrzeugen, das als rohrförmiger Hohlkörper ausgebildet im Behälter in dessen Achsrichtung geführt ist, einen an einer Kappe befestigten Pinsel umgibt und radial nach außen ragende Stege besitzt.The invention relates to an agitator for or the like with colors. filled cylindrical containers, in particular for touch-up pens for repairing paint damage to motor vehicles, which is designed as a tubular hollow body in the container in its axial direction, surrounds a brush attached to a cap and has radially projecting webs.

Es sind Aufrührorgane bekannt (DE-PS 11 61 795), die als gewundenes Drahtstück in der Art einer spiralförmigen Druckfeder ausgebildet sind. Solche Aufrührorgane weisen den Nachteil auf, daß sie in der Regel aus Federstahl hergestellt werden müssen und eine intensive Durchmischung aufgrund ihrer Formgebung nur bei mehrmaligem Schütteln des Behälters zulassen. Die Auslegung muß auch stets so getroffen sein, daß eine gewisse Taumelbewegung des Spiralfederstückes möglich ist, weil sonst in den Bereichen zwischen Außenumfang und Innendurchmesser des Behälters bzw. im Inneren des Spiralfederstückes keine nennenswerte Durchmischung eintreten kann. Es ist daher auch notwendig, auf die Einhaltung von Toleranzen bezüglich des Außendurchmessers und der Länge des Drahtstückes zu achten, wenn ein Verkanten des Aufrührorganes sicher vermieden werden soll.There are stirring elements known (DE-PS 11 61 795), which are designed as a winding piece of wire in the manner of a spiral compression spring. Such stirring elements have the disadvantage that they generally have to be made from spring steel and, because of their shape, allow intensive mixing only when the container is shaken several times. The design must also always be such that a certain wobbling movement of the spiral spring piece is possible, because otherwise no significant mixing can occur in the areas between the outer circumference and the inner diameter of the container or inside the spiral spring piece. It is therefore also necessary to adhere to tolerances regarding the outer diameter and the length of the wire piece to be observed if tilting of the stirring element should be avoided.

Bekannt sind auch Aufrührorgane der eingangs genannten Art (DE-OS 21 27 748), bei denen gelochte Scheiben oder kreuzförmige Teile in Achsrichtung versetzt zueinander einen rohrförmigen Innenteil umgeben. Dadurch wird zwar ein Organ geschaffen, das bei der Schüttelbewegung in Achsrichtung große Bereiche des Querschnittes des Behälters erfaßt. Nachteilig ist aber, daß dadurch auch der Widerstand des Aufschüttelorganes gegen eine axiale Bewegung wächst und daß verhältnismäßig große Berührungsflächen zwischen der untersten Scheibe und dem Behälterboden entstehen, an denen ein Verkleben mit den Pigmenten des Lackes eintreten kann. Ein Lösen ist dann nur noch sehr schwer oder gar nicht mehr möglich.Also Aufrührorgane the aforementioned A are known rt (D E-OS 21 27 748), in which perforated plates or cross-shaped parts in the axial direction offset from one another surround a tubular inner part. As a result, an organ is created which covers large areas of the cross section of the container during the shaking movement in the axial direction. It is disadvantageous, however, that this increases the resistance of the shaking element to axial movement and that relatively large contact surfaces are formed between the lowest disc and the bottom of the container, to which sticking with the pigments of the lacquer can occur. It is then very difficult or even impossible to loosen.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Aufrührorgan der eingangs genannten Art so auszubilden, daß in allen Bereichen des Behälters eine intensive Durchmischung eintritt, auch wenn der Behälter zum Zweck der Bewegung des Aufrührorganes nur wenig geschüttelt wird.The invention is therefore based on the object of designing a stirring element of the type mentioned in such a way that intensive mixing occurs in all areas of the container, even if the container is shaken only slightly for the purpose of moving the stirring element.

Die Erfindung besteht darin, daß die Stege in der Art von Schaufeln eines Gebläserades ausgebildet und gleichmäßig auf dem Umfang des als zylindrisches Rohr ausgebildeten Hohlkörpers verteilt sind, wobei die Außenkanten der Stege auf einem gedachten Zylinder liegen, dessen Durchmesser kleiner als der Innendurchmesser des Behälters ist. Diese Ausgestaltung erlaubt eine einfache Herstellung des Aufrührorganes, beispielsweise als Spritzteil aus Kunststoff oder aus Metall. Sie gibt durch die propellerartig wirkenden Stege die Gewähr für eine ausgezeichnete Durchmischung, auch bei geringfügigen Schüttelvorgängen. Dabei ist es sehr vorteilhaft, wenn die Außenkanten der Stege auf einem gedachten Zylinder liegen, dessen Durchmesser geringfügig kleiner als der Innendurchmesser des Behälters ist, weil dadurch auch die Randbereiche der im Behälter vorgesehenen Flüssigkeit schon bei einem einma - ligen Auf- und Abbewegen des Aufrührorganes erfaßt werden können und nicht erst durch mehrmalige Taumelbewe - gungen eines Aufrührorganes durchmischt werden. Vorteilhaft ist auch, daß die mit dem Boden des den Lack enthaltenden Behälters in Berührung kommende Fläche, die im wesentlichen nur den Stirnflächen der Stege entspricht, sehr klein gehalten werden kann. Ein Ankleben des Aufrührorganes ist daher auch bei längerem Nichtgebrauch nicht zu befürchten.The invention consists in that the webs are designed in the manner of blades of an impeller and are evenly distributed over the circumference of the hollow body designed as a cylindrical tube, the outer edges of the webs lying on an imaginary cylinder, the diameter of which is smaller than the inner diameter of the container . This configuration allows simple production of the stirring element, for example as a molded part made of plastic or metal. Due to the propeller-like bars, it guarantees excellent mixing, even with minor shaking processes. It is very advantageous if the outer edges of the webs lie on an imaginary cylinder, the diameter of which is slightly smaller than the inside diameter of the container, because this means that the edge areas of the liquid provided in the container can already be detected with a single up and down movement of the stirring element and are not mixed by repeated tumbling movements of a stirring element. It is also advantageous that the area which comes into contact with the bottom of the container containing the lacquer and which essentially corresponds only to the end faces of the webs, can be kept very small. It is therefore not to be feared that the agitator will stick on even if it is not used for a long time.

Diese vorteilhaften Eigenschaften können noch verbessert werden, wenn die axiale Länge des Hüllzylinders für die Außenkanten der Schaufeln größer als die Länge des Rohres gewählt ist und wenn die Stirnkanten der Schaufeln unter einem Winkel zur Längsachse nach innen verlaufen. Durch diese Ausgestaltung ergeben sich nur punkförmige Auflagestellen im äußersten Bereich der Schaufeln, so daß die Berührungsflächen mit dem Boden des Behälters des Lackstiftes auf ein Minimum reduziert sind. Die neue Ausgestaltung sicher daher in jedem Fall die freie Beweglichkeit des Aufrührorganes im Lackbehälter.These advantageous properties can be further improved if the axial length of the enveloping cylinder for the outer edges of the blades is selected to be greater than the length of the tube and if the front edges of the blades extend inwards at an angle to the longitudinal axis. This configuration results in only punctiform contact points in the outermost region of the blades, so that the contact surfaces with the bottom of the paint stick container are reduced to a minimum. The new design therefore ensures in any case the free movement of the stirring element in the paint container.

Vorteilhaft ist auch, wenn bei einer solchen Ausführungsform aus herstellungstechnischen Gründen die Gebläseschaufeln selbst als gerade Schaufelblätter ausgebildet sind, die lediglich unter einem Winkel zur Achsrichtung des Aufrührorganes angestellt sind. Ein solches Aufrührorgan kann in sehr einfacher Weise, beispielsweise im Spritzgußverfahren, aus Metall hergestellt werden.It is also advantageous if, in the case of such an embodiment, for technical reasons, the fan blades themselves are designed as straight blades, which are only set at an angle to the axial direction of the stirring element. Such a stirring element can be made from metal in a very simple manner, for example by injection molding.

Es hat sich als ausreichend und als vorteilhaft erwiesen, wenn vier schaufelförmige Stege vorgesehen sind, deren beide Stirnseiten senkrecht zu der Rohrwandung stehen und in Umfangsrichtung zueinander versetzt sind. Bei dieser Ausführung können sich zwischen den schaufelartigen Stegen Durchströmungskanäle bilden, die dann, wenn die Länge des Aufrührorganes etwa so ausgelegt ist, daß sie der Hälfte der im Behälter für die Axialbewegung des Aufrührorganes zur Verfügung stehenden Länge entspricht, bei einem einmaligen Schüttelvorgang schon eine ausreichende Drehung des Aufrührorganes bewirken, die in die gewünschte Mischbewegung der Flüssigkeit umgesetzt wird. Diese neue Ausführung des Aufrührorganes erlaubt daher eine sichere einwandfreie Führung des Aufrührorganes im Behälter, eine einfache Herstellung und einen ausgezeichneten Mischeffekt, ohne daß der im Behälter vorgesehene Pinsel von dem sich bewegenden Aufrührorgan beschädigt oder berührt werden könnte.It has proven to be sufficient and advantageous if four scoop-shaped webs are provided, the two end faces of which are perpendicular to the tube wall and are offset from one another in the circumferential direction. In this embodiment, flow channels can form between the scoop-like webs, which, if the length of the stirring element is approximately designed so that it corresponds to half the length available in the container for the axial movement of the stirring element, is sufficient in a single shaking operation Cause rotation of the agitator, which is converted into the desired mixing movement of the liquid. This new design of the agitator therefore allows safe, reliable guidance of the agitator in the container, simple manufacture and an excellent mixing effect without the brush provided in the container being damaged or touched by the moving agitator.

Die Erfindung ist in der Zeichnung anhand von Ausführungsbeispielen dargestellt und in der nachfolgenden Beschreibung erläutert. Es zeigen
Figur 1 einen Längsschnitt durch einen Lackstift zur Ausbesserung von Lackschäden an Kraftfahrzeugen, in dem ein erfindungsgemäßes Aufrührorgan eingesetzt ist, Figur 2 eine perspektivische Darstellung des in dem Lackstift der Figur 1 vorgesehenen Aufrührorganes, Figur 3 eine perspektische Ansicht eines neuen Aufrührorganes, bei dem die Stirnkanten der einzelnen Gebläseschaufeln schräg zum Zentrum hin verlaufen und Figur 4 eine Seitenansicht eines Aufrührorganes, ähnlich Figur 1, bei dem jedoch die einzelnen Schaufeln nicht in sich gewunden, sondern als gerade, lediglich zur Achse angestellte Schaufelblätter ausgebildet sind.The invention is illustrated in the drawing using exemplary embodiments and explained in the description below. Show it
1 shows a longitudinal section through a touch-up pen for repairing paint damage to motor vehicles, in which a stirring element according to the invention is used, FIG. 2 shows a perspective view of the stirring element provided in the touch-up stick of FIG. 1, FIG. 3 shows a perspective view of a new stirring element in which the front edges of the individual fan blades run obliquely towards the center, and FIG. 4 shows a side view of a stirring element, similar to FIG. 1, but in which the individual blades are not convoluted, but rather are formed as straight blades that are only aligned with the axis.

In der Fig. 1 ist in einen zylindrischen Behälter 1 eines Lackstiftes zur Ausbesserung von Lackschäden an Kraftfahrzeugen ein Verschlußstopfen 2 eingesetzt, der fest mit dem oberen Rand des Behälters 1 verbunden ist. Der Verschlußstopfen 2 trägt ein Außengewinde 3, auf das eine Schraubkappe 4 aufgesetzt ist, die in bekannter Weise ausgebil - det ist. Diese Schraubkappe 4 besitzt einen konischen Ansatz 5, in dem ein Pinsel 6 fest eingeklemmt ist. Sie besitzt außerdem, ebenfalls in bekannter Weise, einen inneren Hohlraum 7, der oben durch eine zusätzliche Kappe 8 abgedeckt ist. In diesem Hohlraum kann beispielsweise Spachtelmaterial oder anderes für die Ausbesserungsarbeiten des Lackschadens benötigtes Material eingesetzt sein.In Fig. 1, a sealing plug 2 is inserted into a cylindrical container 1 of a paint pen for repairing paint damage to motor vehicles, which is firmly attached to the upper edge of the container 1 is connected. The sealing plug 2 has an external thread 3 on which a screw cap 4 is placed, which is designed in a known manner. This screw cap 4 has a conical neck 5, in which a brush 6 is firmly clamped. It also has, also in a known manner, an inner cavity 7 which is covered at the top by an additional cap 8. For example, filler material or other material required for the repair work of the paint damage can be used in this cavity.

In den Behälter 1 ist ein Aufrührorgan 9 eingesetzt, das dazu dient, die in dem Behälter 1 befindliche Lackfarbe aufzurühren, ehe mit der Ausbesserungsarbeit begonnen wird. Das geschieht dadurch, daß der Behälter 1 im verschlossenen Zustand in Achsrichtung hin und her geschüttelt wird, wodurch das Aufrührorgan 9 aufgrund seiner Trägheit eine Axialbewegung innerhalb des Behälters 1 ausführt.In the container 1, a stirring element 9 is inserted, which serves to stir up the paint in the container 1 before starting the repair work. This is done in that the container 1 is shaken back and forth in the closed state in the axial direction, as a result of which the stirring element 9 executes an axial movement within the container 1 due to its inertia.

Das Aufrührorgan 9 besteht, wie insbesondere auch aus Fig. 2 hervorgeht, aus einem zylindrischen Rohr 10, an dessen Umfang schraubenförmig zu der Längsachse 11 verlaufende Stege 12 vorgesehen sind, die in der Art der Schaufeln eines Gebläserades ausgebildet sind. Beim gezeigten Ausführungsbeispiel sind vier Stege 12 vorgesehen, deren obere Stirnseiten 13 jeweils um 900 versetzt zueinander am Umfang des Rohres 1 angeordnet sind, und zwar so, daß sie mit der oberen Stirnseite 10a des Rohres 10 in einer Radialebene liegen, die senkrecht zu der Längsachse 11 steht. Die unteren Stirnflächen 14, die ebenfalls mit der unteren Stirnfläche des Rohres 10 fluchten, sind jeweils zu den zugeordneten oberen Stirnflächen eines jeden Steges etwa um 90° in Umfangsrichtung versetzt, so daß sich die Eingangsquerschnitte der zwischen den Stegen 12 gebildeten Strömungskanäle jeweils ebenfalls etwa um 900 versetzt gegenüberstehen. Die Gesamtlänge 1 des Rohres 10 und der Stege 12 ist so gewählt, daß sie etwa einem Drittel bis der Hälfte der gesamten im Behälter 1 zur Axialbewegung des Aufrührorganes 9 zur Verfügung stehenden Länge L entspricht. Durch diese Ausgestaltung genügt unter Umständen schon ein einziger Aufschüttelvorgang, um die im Behälter 1 befindliche Lackfarbe durch den vom Aufrührorgan ausgeübten Drall ein - wandfrei zu durchmischen. Es ist natürlich auch möglich, die Stege 12 unter einem geringeren Winkel zu Längsachse 11 anzustellen, so daß die Stirnseiten 13 und 14 eines jeden Steges beispielsweise nur etwa um 450 oder 600 zueinander versetzt sind. Maßgebend ist, daß die Stege in der Art von Gebläseschaufeln auf die Lackfarbe einwirken sollen, wenn das Aufrührorgan 9 eine Axialbewegung - bedingt durch das Schütteln des Behälters 1 - innerhalb des Behälters 1 ausführt.The stirring element 9 consists, as can also be seen in particular from FIG. 2, of a cylindrical tube 10, on the circumference of which helical webs 12 extending to the longitudinal axis 11 are provided, which are designed in the manner of the blades of an impeller. In the illustrated embodiment, four ribs 12 are provided, the upper end faces 13 at 90 0 offset from one another on the circumference of the tube 1 are arranged, in such a way that they lie with the upper end face 10a of the pipe 10 in a radial plane perpendicular to the Longitudinal axis 11 is. The lower end faces 14, which are also aligned with the lower end face of the tube 10, are each offset by approximately 90 ° in the circumferential direction from the assigned upper end faces of each web, so that the input cross sections of the flow channels formed between the webs 12 are also each different approximately offset by 90 0 face. The total length 1 of the tube 10 and the webs 12 is selected so that it corresponds to approximately one third to half of the total length L available in the container 1 for the axial movement of the stirring element 9. As a result of this configuration, a single shaking operation may be sufficient to mix the paint color in the container 1 without problems by the swirl exerted by the stirring element. It is of course also possible to position the webs 12 at a smaller angle to the longitudinal axis 11, so that the end faces 13 and 14 of each web are, for example, only offset by approximately 45 ° or 60 ° from one another. The decisive factor is that the webs should act on the paint color in the manner of fan blades when the agitating element 9 executes an axial movement - due to the shaking of the container 1 - within the container 1.

Die Außenkanten 15 der Stege 12 liegen beim Ausführungsbeispiel auf einem gedachten Zylinder, dessen Durchmesser geringfügig kleiner als der Innendurchmesser des Behälters 1 ist. Dadurch kann das Aufrührorgan einwandfrei innerhalb des Behälters 1 geführt werden, ohne daß eine Beschädigung des Pinsels 6 zu befürchten ist. Vorteilhaft ist dann auch, daß der gesamte Innenbereich des Behälters 1 bei einem Aufschüttelvorgang von der Drallwirkung des Aufrührorganes 9 erfaßt wird, wobei der Innenraum des Rohres 10 an dem Mischvorgang dadurch teilnimmt, daß im Innenraum des Rohres 10 das untere Ende des Pinsels 6 sich relativ gegenüber dem Rohr 10 bewegt. Die neue Ausgestaltung erlaubt daher eine ausgezeichnete Durchmischung der Farbe im Behälter 1 beim Aufschütteln.In the exemplary embodiment, the outer edges 15 of the webs 12 lie on an imaginary cylinder, the diameter of which is slightly smaller than the inner diameter of the container 1. As a result, the stirring element can be guided properly within the container 1 without fear of damage to the brush 6. It is then also advantageous that the entire inner region of the container 1 is detected by the swirling action of the stirring element 9 during a shaking process, the interior of the tube 10 taking part in the mixing process in that the lower end of the brush 6 is relative in the interior of the tube 10 moved relative to the tube 10. The new design therefore allows excellent mixing of the color in the container 1 when shaken.

Das Aufrührorgan 9 kann in sehr einfacher Weise als ein einziges Teil im Spritzgußverfahren hergestellt werden. Schwierigkeiten bei der Formgebung treten nicht auf. Dabei kann als Herstellungsmaterial Metall, beispielsweise Zinkguß, oder auch Kunststoff verwendet werden.The stirring element 9 can be produced in a very simple manner as a single part by injection molding. There are no design difficulties. There can be used as the production material metal, such as cast zinc, or plastic.

Das in der Fig. 3 gezeigte Aufrührorgan 9 besteht aus einem inneren zylindrischen Rohr 10, an dessen Umfang schraubenförmig zu dessen Längsachse 11 verlaufende Stege 12 vorgesehen sind, die wie bei den Fig. 1 und 2 in der Art der Schaufeln eines Gebläserades ausgebildet und angeordnet sind. Die Stirnseiten 13' jedes der Stege 12 sind im Gegensatz zu der Ausführung der Fig. 1 und 2 nicht in einer gemeinsamen Ebene angeordnet, die mit der Stirnseite des Rohres 11 fluchtet, sondern sie sind, wie insbesondere aus Fig. 2 hervorgeht, unter einem Winkel aC zur Längsachse 11 geneigt angeordnet, und zwar so, daß sie ausgehend von dem gedachten Hüllzylinder von der Länge L, der die Außenkanten 15 der einz.elnen schaufelartigen Stege 12 aufnimmt, schräg nach innen auf die Länge 1 des Rohres 10 zurückgeführt sind. An den beiden äußersten stirnseitigen Begrenzungen des Aufrührorganes 9, die im Abstand L zueinander angeordnet sind, ergeben sich daher bei den beiden gezeigten Ausführungsbeispielen auf jeder Seite nur vier etwa punktförmige Stellen 20, welche beim Einsatz des Aufrührorganes 9 in zylindrischen Lackbehältern nach den Fig. 1 und 2 zur Anlage mit dem Boden des Lackbehälters kommen können. Die Berührungsflächen zwischen Lackbehälter und Aufrührorgan 9 sind daher auf ein Minimum reduziert. Das neue Aufrührorgan kann daher nicht mit Pigmenten des Lackes nach längerem Stehen am Boden des Lackbehälters verkleben.The stirring element 9 shown in FIG. 3 consists of an inner cylindrical tube 10, on the circumference of which screws 12 are provided which extend helically to the longitudinal axis 11 and which, as in FIGS. 1 and 2, are designed and arranged in the manner of the blades of an impeller are. In contrast to the embodiment of FIGS. 1 and 2, the end faces 13 'of each of the webs 12 are not arranged in a common plane which is aligned with the end face of the tube 11, but rather, as can be seen in particular from FIG. 2, under one Angle aC is arranged inclined to the longitudinal axis 11, in such a way that, starting from the imaginary envelope cylinder of length L, which receives the outer edges 15 of the individual blade-like webs 12, they are returned obliquely inward to the length 1 of the tube 10. At the two outermost end boundaries of the stirring element 9, which are arranged at a distance L from one another, there are therefore only four approximately punctiform points 20 on each side in the two exemplary embodiments shown, which, when the stirring element 9 is used in cylindrical paint containers according to FIG. 1 and 2 can come to rest with the bottom of the paint container. The contact surfaces between the paint container and stirring element 9 are therefore reduced to a minimum. The new agitator can therefore not stick to the paint pigments after standing for a long time at the bottom of the paint container.

Wie aus Fig. 4 hervorgeht, sind dort die als Gebläseschaufeln ausgebildeten Stege 12 lediglich unter einem Winkel zu der Längsachse 11 geneigt, in sich aber nicht noch einmal verwunden. Es hat sich gezeigt, daß die beim Aufschüttelvorgang des Lackes bewirkende Kraftkomponente groß genug ist, um eine ausreichende Vermischung zu erzielen. Wenn das in der Fig. 4 gezeigte Aufrührorgan aber einstückig, beispielsweise aus Metallguß hergestellt wird, kann die dafür benötigte Form wesentlich einfacher gestaltet werden.As can be seen from FIG. 4, the webs 12 designed as fan blades are only inclined at an angle to the longitudinal axis 11, but are not twisted again. It has been shown that the force component which causes the lacquer to be shaken is large enough to achieve sufficient mixing. If the stirring element shown in FIG. 4 is a lumpy, for example made of cast metal, the shape required for this can be made much easier.
