Abstract

The invention relates to a process for producing floatable hollow clay bodies, a gypsum mould, which is closed with the exception of a filling opening, being filled with a flowable clay composition, there remaining adhered to the interior surface of the gypsum mould a solid clay layer the thickness of which is dependent on the residence time and which, after the pouring out of the excess clay composition in the gypsum mould, forms a hollow body which, after initial drying, is removed from the gypsum mould, glazed and fired. Using the process, it should be possible to produce hollow bodies which, after they have been placed on a water surface, always assume a desired floating position and retain this. This is achieved in that, after the initial drying of the hollow body, it is preferably partly filled with a further clay composition while still in the gypsum mould and, after the initial drying of a suitable amount of the clay composition, the remainder of the clay composition is emptied out again, whilst, during the initial drying time, the hollow article is rotated and held in a position such that the aforementioned amount of clay composition dries in a layer which stabilises the desired floating position. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von schwimmfähigen Hohlkörpern aus Ton, wobei eine bis auf eine Einfüllöffnung geschlossene Gipsform mit einer fließfähigen Tonmasse gefüllt wird, wobei an der inneren Oberfläche der Gipsform eine feste, in der Dicke von der Verweilzeit abhängige Tonschicht haften bleibt, die nach dem Ausgießen der überflüssigen Tonmasse in der Gipsform einen Hohlkörper bildet, der nach einer Antrocknung aus der Gipsform entnommen, glasiert und gebrannt wird,The invention relates to a process for the production of buoyant hollow bodies made of clay, wherein a plaster mold which is closed except for a filling opening is filled with a flowable clay mass, a solid clay layer which depends on the residence time adhering to the inner surface of the plaster mold and which remains after pouring out the excess clay in the gypsum mold, it forms a hollow body which, after drying, is removed from the gypsum mold, glazed and fired,

Die Herstellung von Hohlkörpern aus Ton ist bekannt. Bei diesen Hohlkörpern handelt es sich meist um Tiernachbildungen, wie beispielsweise Frösche, Enten, Fische oder dergl., die als Dekoration oder Sammelobjekt in Wohnungen aufgestellt werden. Derartige Hohlkörper sind in der Regel trotz ihrer Öffnung auch schwimmfähig, dies jedoch nur in bedingtem Maße, da sie eine sehr ungünstige Massenverteilung aufweisen und somit auf dem Wasser eine beliebige, bzw. labile Schwimmlage einnehmen. Hierbei kann es vorkommen, daß sie mit ihren Öffnungen unter den Wasserspiegel gelangen und somit voll Wasser laufen und absinken. Geschlossene Hohlkörper in Form einer Tiernachbildung nehmen dagegen auf dem Wasser eine derart unnatürliche Schwimmlage ein, daß in der Regel davon abgesehen wird, die Hohlkörper auf das Wasser zu setzen.The production of hollow bodies from clay is known. These hollow bodies are mostly animal replicas, such as frogs, ducks, fish or the like, which are placed in apartments as a decoration or collector's item. Such hollow bodies are generally buoyant despite their opening, but only to a limited extent, since they have a very unfavorable mass distribution and thus assume any arbitrary or unstable swimming position on the water. It can happen that their openings get below the water level and thus run full of water and sink. Closed hollow bodies in the form of an animal replica, on the other hand, assume such an unnatural floating position on the water that, as a rule, the hollow bodies are not placed on the water.

Der Erfindung liegt somit die Aufgabe zugrunde, ein Verfahren der eingangs beschriebenen Art vorzuschlagen, mit dem es möglich ist, schwimmfähige Hohlkörper aus Ton herzustellen, die, wenn sie auf das Wasser gesetzt werden, stets eine stabile Schwimmlage einnehmen.The invention is therefore based on the object of proposing a method of the type described at the outset with which it is possible to produce buoyant hollow bodies made of clay which, when placed on the water, always assume a stable swimming position.

Erfindungsgemäß wird diese Aufgabe mit einem Verfahren der eingangs beschriebenen Art dadurch gelöst, daß nach dem Antrocknen des Hohlkörpers dieser vorzugsweise noch in der Gipsform mit einer vorbestimmten Menge Tonmasse gefüllt und nach der Antrocknung einer geeigneten Menge der Tonmasse ein eventueller Rest der Tonmasse wieder entleert wird, wobei während der Antrocknungszeit der Hohlkörper in eine solche Lage gedreht und in dieser gehalten wird, daß die genannte Menge der Tonmasse in einer Lage austrocknet, die die gewünschte Schwimmlage stabilisiert. Hierdurch ist es möglich, einen Hohlkörper herzustellen, der, wenn er auf das Wasser gesetzt wird, stets eine gewünschte stabile Schwimmlage einnimmt.According to the invention, this object is achieved with a method of the type described in the introduction in that after the hollow body has dried, it is preferably still filled in the plaster mold with a predetermined amount of clay and any residual clay is emptied again after the drying of a suitable amount of clay. wherein during the drying time the hollow body is rotated into such a position and held in such a way that said amount of clay mass dries out in a position which stabilizes the desired floating position. This makes it possible to produce a hollow body which, when placed on the water, always assumes a desired stable swimming position.

Darüber hinaus ist es nach dem Verfahren möglich, bereits bei der Herstellung die spätere Schwimmlage des Hohlkörpers zu bestimmen. Sollen beispielsweise Enten hergestellt werden, so kann durch die Anordnung der weiteren Tonmasse im Hohlkörper auf dem Wasser entweder eine Bauchlage eingenommen werden, oder aber die Schwimmlage so bestimmt werden, daß die Ente beispielsweise mit dem Kopf unter den Wasserspiegel taucht.In addition, the method makes it possible to determine the later floating position of the hollow body during manufacture. If, for example, ducks are to be produced, the arrangement of the additional clay mass in the hollow body on the water can either take a prone position, or the swimming position can be determined such that the duck dips his head under the water level, for example.

Nach einer Ausgestaltung der Erfindung wird vorgeschlagen, daß eine Gipsform mit einer die Unterseite des Hohlkörpers offenlassende Einfüllöffnung verwendet wird. Vorteilhaft kann hierbei mit der in den Hohlkörper eingefüllten weiteren Tonmasse in der gleichen Lage des Hohlkörpers auch die Einlaßöffnung verschlossen werden.According to one embodiment of the invention, it is proposed that a plaster mold be used with a filling opening that leaves the underside of the hollow body open. Advantageously, the inlet opening can also be closed with the additional clay mass filled into the hollow body in the same position of the hollow body.

Nach einer weiteren Ausgestaltung der Erfindung wird vorgeschlagen, daß eine Gipsform mit einer die Oberseite des Hohlkörpers offenlassende Einfüllöffnung verwendet wird. Hierdurch kann die weitere Tonmasse sehr leicht in den Hohlkörper eingefüllt werden, wobei die Einfüllöffnung nicht geschlossen werden braucht und beispielsweise später der Aufnahme eines kleinen Blumentopfs mit einer Pflanze dienen kann, wodurch der schwimmfähige Hohlkörper gleichzeitig zum dekorativen Übertopf werden kann.According to a further embodiment of the invention, it is proposed that a plaster mold be used with a filling opening that leaves the top of the hollow body open. As a result, the additional clay mass can be very easily filled into the hollow body, the filling opening need not be closed and can later serve, for example, to accommodate a small flower pot with a plant, whereby the floatable hollow body can simultaneously become a decorative planter.

Nach einer Alternativen wird die erfindungsgemäße Aufgabe, ausgehend von einem Verfahren der eingangs beschriebenen Art, dadurch gelöst, daß eine weitere Tonmasse mit geeigneter Masseverteilung vormodelliert und zur Erzeugung der gewünschten Schwimmlage an der Unterseite des Hohlkörpers angebracht wird. Vorteilhaft kann hierdurch die weitere Tonmasse, aber auch der Hohlkörper, in großer Stückzahl vormodelliert werden, wobei bereits gewünschte unterschiedliche Schwimmlagen der Hohlkörper berücksicht werden können. Die Fertigung wird hierdurch sehr erleichtert.According to an alternative, the object according to the invention, based on a method of the type described in the introduction, is achieved in that a further clay mass with a suitable mass distribution is pre-modeled and attached to the underside of the hollow body to produce the desired floating position. In this way, the additional clay mass, but also the hollow body, can advantageously be pre-modeled in large numbers, wherein the desired different floating positions of the hollow body can be taken into account. This greatly simplifies production.

Ferner wird nach einer Ausgestaltung der Erfindung vorgeschlagen, daß die Einfüllöffnung des Hohlkörpers mit der weiteren Tonmasse geschlossen wird. Dadurch, daß die Einfüllöffnungen sowohl an der Unterseite wie auch an der Oberseite durch die weitere Tonmasse geschlossen werden, sind die Hohlkörper, wenn sie nicht zerstört werden, unsinkbar und eignen sich damit beispielsweise als dekorativer Dauerbesatz eines Gartenteiches.Furthermore, it is proposed according to an embodiment of the invention that the filling opening of the hollow body is closed with the further clay. Characterized in that the filler openings are closed both on the underside and on the top by the additional clay mass, the hollow bodies, if they are not destroyed, are unsinkable and are therefore suitable, for example, as a decorative permanent trim of a garden pond.

Die Erfindung soll nun anhand der beigefügten Zeichnungen näher erläutert werden. Es zeigen:

The invention will now be explained in more detail with reference to the accompanying drawings. Show it:

Figur 1 zeigt schematisch dargestellt eine Hälfte einer Gipsform 6, mit der ein Hohlkörper 2 in Form einer Ente hergestellt werden kann. Die erste Hälfte der Gipsform 6 bildet zusammen mit der zweiten Hälfte eine die Unterseite 4 des Hohlkörpers 2 offenlassende Einfüllöffnung 1. Zur Herstellung des Hohlkörpers wird die zusammengesetzte Gipsform durch diese Einfüllöffnung 1 mit gießfähiger Tonmasse vollständig gefüllt. Der Gips entzieht der Füllung Wasser, so daß nach kurzer Zeit bereits eine feste Tonschale entsteht, deren Wandstärke mit der Verweildauer der Tonmasse zunimmt. Ist die gewünschte Wandstärke erreicht, wird die überflüssige Tonmasse abgeschüttet. Sodann kann durch diese Einfüllöffnung 1 kann, nachdem die überflüssige Tonmasse ausgegossen wurde und die in der Gipsform verbleibende, den Hohlkörper 2 bildende, Tonschicht angetrocknet ist, die weitere Tonmasse 3 in den Hohlkörper 2 eingegossen werden. Nachdem die weitere Tonmasse 3 in den Hohlkörper gegossen wurde, wird die Gipsform bzw. der Hohlkörper in die Lage gedreht und in dieser gehalten, in der die weitere Tonmasse 3 an den Ort läuft und dort trocknet, der aufgrund der Massenanhäufung die gewünschte Schwimmlage stabilisiert. Nachdem die weitere Tonmasse 3 an der vorgesehenen Stelle im Innnern des Hohlkörpers getrocknet ist, kann der Hohlkörper der Gipsform entnommen, glasiert und gebrannt werden. Vorteilhaft kann mit der weiteren Tonmasse 3 gleichzeitig die Einfüllöffnung 1 des Hohlkörpers verschlossen werden.FIG. 1 schematically shows one half of a plaster mold 6 with which a hollow body 2 in the form of a duck can be produced. The first half of the plaster mold 6 forms, together with the second half, a filling opening 1 which leaves the underside 4 of the hollow body 2 open. To produce the hollow body, the assembled plaster mold is completely filled with pourable clay mass through this filling opening 1. The plaster removes water from the filling, so that after a short time a solid clay bowl is formed, the wall thickness of which increases with the length of time the clay remains. When the desired wall thickness is reached, the excess clay is poured off. Then, through this filling opening 1, after the excess clay has been poured out and the clay layer remaining in the gypsum mold and forming the hollow body 2 has dried, the further clay 3 can be poured into the hollow body 2. After the further clay mass 3 has been poured into the hollow body, the plaster mold or the hollow body is rotated and held in the position in which the further clay mass 3 runs to the place and dries there, which stabilizes the desired swimming position due to the mass accumulation. After the additional clay mass 3 has dried at the intended location inside the hollow body, the hollow body can be removed from the plaster mold, glazed and fired. The filling opening 1 of the hollow body can advantageously be closed at the same time with the further clay mass 3.

Figur 2 zeigt schematisch dargestellt eine Hälfte einer Gipsform 6', bei der der Hohlkörper durch eine die Oberseite 8 des Hohlkörpers 2' offenlassende Einfüllöffnung 1' gegossen wird. Ebenso wie in Figur 1 wird hier als Hohlkörper die Form einer Ente dargestellt. Anders als in Figur 1 ist jedoch die weitere Tonmasse 3' nicht in einem unteren Bereich 5 zur Bestimmung und Stabilisierung der Schwimmlage angeordnet, sondern in einem vorderen Bereich 10 unterhalbe des Kopfes 11 der Ente. Hierdurch wird beispielsweise die in Figur 2 gezeigte Ente mit ihrem Kopf unterhalb des Wasserspiegels tauchen, während die in Figur 1 gezeigte Ente in einer Bauchlage schwimmt.FIG. 2 schematically shows one half of a plaster mold 6 'in which the hollow body is poured through a filling opening 1' which leaves the top 8 of the hollow body 2 'open. As in FIG. 1, the shape of a duck is shown here as a hollow body. In contrast to FIG. 1, however, the further clay mass 3 'is not arranged in a lower region 5 for determining and stabilizing the floating position, but in a front region 10 below it 11 duck's head. In this way, for example, the duck shown in FIG. 2 will dive with its head below the water level, while the duck shown in FIG. 1 swims in a prone position.

Wie in Figur 3 schematisch dargestellt, braucht ein Hohlkörper 2'', der in einer Gipsform 6' mit einer die Oberseite des Hohlkörpers offenlassende Einfüllöffnung 1' hergestellt wurde, nicht verschlossen werden. Ist wie in Figur 1 gezeigt, die weitere Tonmasse 3 im unteren Bereich 5 des Hohlkörpers 2'' angeordnet, so nimmt der Hohlkörper bzw. die Ente, wenn sie auf das Wasser gesetzt wird, eine Bauchlage ein, wodurch es möglich wird, einen kleineren Blumentopf mit einer Pflanze in die durch die Einfüllöffnung bestimmte Öffnung 9 des Hohlkörpers 2'' zu setzen und diese mit dem Hohlkörper auf dem Wasser treiben zu lassen.
Darüber hinaus ist es durch die an der Oberseite 8 des Hohlkörpers 2'' befindliche Öffnung 9 möglich, den Hohlkörper auch als dekorativen Übertopf zu nutzen.As shown schematically in FIG. 3, a hollow body 2 ″, which was produced in a plaster mold 6 ′ with a filling opening 1 ′ that leaves the top of the hollow body open, does not need to be closed. If, as shown in FIG. 1, the further clay mass 3 is arranged in the lower region 5 of the hollow body 2 ″, the hollow body or the duck, when placed on the water, takes up a prone position, which makes it possible to make a smaller one Place a flower pot with a plant in the opening 9 of the hollow body 2 ″ determined by the fill opening and let it float on the water with the hollow body.
In addition, through the opening 9 located on the top 8 of the hollow body 2 ″, it is also possible to use the hollow body as a decorative planter.

Vorteilhaft ist es nach einer Ausgestaltung des erfindungsgemäßen Verfahrens auch möglich, wie in Figur 4 gezeigt, die weitere Tonmasse 3'' in großer Stückzahl vorzufertigen und die vormodellierte weitere Tonmasse 3'' von außen an eine Unterseite 4 bzw. in einem unteren Bereich 5 des Hohlkörpers 2''' anzubringen. Hierbei kann durch eine entsprechende Massenverteilung in der vormodellierten weiteren Tonmasse 3'' bereits eine gewünschte spätere Schwimmlage des Hohlkörpers 2''' berücksichtigt werden. Ferner ist es möglich, die weitere Tonmasse 3'' mit der entsprechenden Masse auch als Gliedmaßen von den dargestellten Tierkörpern auszuführen. In dem Beispiel der Figur 4 werden beispielsweise in einem geeigneten Bereich der Unterseite der Ente Entenfüße derart angebracht, daß die Ente auf dem Wasser die gewünschte Schwimmlage einnimmt.According to an embodiment of the method according to the invention, it is also possible, as shown in FIG. 4, to prefabricate the further clay mass 3 ″ in large numbers and the pre-modeled further clay mass 3 ″ from the outside to a lower side 4 or in a lower region 5 of the Attach hollow body 2 '' '. In this case, a desired later floating position of the hollow body 2 '' 'can already be taken into account by a corresponding mass distribution in the pre-modeled further clay mass 3' '. It is also possible to design the further clay mass 3 ″ with the corresponding mass as limbs of the carcasses shown. In the example in FIG. 4, for example, duck feet are attached in a suitable area of the underside of the duck in such a way that the duck assumes the desired swimming position on the water.

Mit der Erfindung wird somit ein Verfahren vorgeschlagen, mit dem es möglich ist, schwimmfähige Hohlkörper herzustellen, die, wenn sie auf das Wasser gesetzt werden, stets eine gewünschte Schwimmlage einnehmen und diese beibehalten. Ein nach dem Verfahren hergestellter Hohlkörper kann beispielsweise in Form von Tiernachbildungen wie Enten, Frösche oder Fische, als geschlossener Hohlkörper als Dauerbesatz zur Dekoration auf Gartenteiche gesetzt werden oder aber als offener Hohlkörper mit einer Öffnung auf der Oberseite einen Blumentopf mit einer Pflanze aufnehmen und diese auf dem Wasser tragen. Darüber hinaus eignen sich schwimmfähige Hohlkörper mit einer Öffnung an der Oberseite auch als dekorative Übertöpfe.The invention thus proposes a method with which it is possible to produce floatable hollow bodies which, when placed on the water, always assume a desired swimming position and maintain it. A hollow body produced by the process can be placed, for example, in the form of animal replicas such as ducks, frogs or fish, as a closed hollow body as permanent trim for decoration on garden ponds or as an open one Hollow bodies with an opening on the top pick up a flower pot with a plant and carry it on the water. In addition, floatable hollow bodies with an opening on the top are also suitable as decorative planters.
