Description

Die Erfindung betrifft eine Formgebungsvorrichtung zum Umformen eines aus einem festen Schaum bestehenden, plastisch verformbaren Spielbausteins zu einem im wesentlichen quaderförmigen, vorzugsweise länglichen Spielbaustein gemäß dem Oberbegriff des Anspruchs 1. Des weiteren betrifft die Erfindung ein Verfahren zur Formung eines Spielbausteins mit einer derartigen Formgebungsvorrichtung gemäß dem Oberbegriff des Anspruchs 4.The invention relates to a shaping device for forming a a solid foam, plastically deformable toy building block to a substantially cuboid, preferably elongated toy building block according to the preamble of claim 1. Furthermore, the invention relates to a Method for forming a toy building block with such a shaping device according to the preamble of claim 4.

Ein derartiger Spielbaustein ist offenbart in der DE 197 49 493. Der bekannte Spielbaustein ist aus einem Agrarrohstoff durch Spritzgießen geformt und aufgeschäumt. Der Spielbaustein weist näherungsweise eine zylindrische Form mit balligen Stirnflächen auf. Er ist durch Befeuchten selbstklebend und dadurch mit weiteren Spielbausteinen verbindbar. Jedoch weist der bekannte Spielbaustein aufgrund seiner Zylinderform und seiner balligen Stirnflächen keine ebene Außenform aus, wodurch es erschwert ist, beispielsweise eine Modellmauer aus den bekannten Spielbausteinen zu errichten.Such a game module is disclosed in DE 197 49 493. The well-known Game module is molded from an agricultural raw material by injection molding and foamed. The game module has approximately a cylindrical shape crowned faces on. It is self-adhesive by moistening and thus with connectable to other game blocks. However, the well-known game module points due to its cylindrical shape and its crowned faces no flat Out of shape, which makes it difficult, for example, a model wall to build the known game building blocks.

Aus der DE-C-196 28 349 ist eine Vorrichtung zur Herstellung von Formteilen aus aufgeschäumten thermoplastischen Kunststoffpartikeln bekannt, die eine aus mindestens zwei Teilschalen bestehende Form aufinreist, in welche die aufgeschäumten Kunststoffpartikel über eine Einlaßvorrichtung eingebracht und unter Einwirkung von Wärme und Dampf weiter aufgeschäumt, verschweißt und/oder versintert werden. Die bekannte Vorrichtung ist nicht zum Umformen, sondern zum Urformen vorgesehen. Des weiteren weist die bekannte Vorrichtung ebene Formgebungsflächen auf. Wollte man mit der bekannten Vorrichtung einen aus einem festen Schaum bestehenden Spielbaustein zu einem im wesentlichen quaderförmigen Spielbaustein umformen, würden sich Außenflächen des umgeformten Spielbausteins aufgrund seiner Elastizität zu balligen Flächen nach außen wölben. Ein solcher Spielbaustein hätte nicht die gewünschte, im wesentlichen quaderförmige Form, aufeinander gesetzte Spielbausteine würden aufgrund ihrer balligen Außenflächen aufeinander schaukeln, ein Aufeinandersetzen der Spielbausteine zu beispielsweise einer Spielzeugmauer wäre nicht möglich, die Spielzeugmauer würde spätestens bei drei oder vier aufeinander gesetzten Spielbausteinen einstürzen.From DE-C-196 28 349 is an apparatus for the production of moldings made of foamed thermoplastic resin particles known, the one consisting of at least two subshells, into which the foamed plastic particles introduced via an inlet device and further foamed under the action of heat and steam, welded and / or sintered. The known device is not for forming, but intended for archetypes. Furthermore, the known device planar shaping surfaces. Did you want with the known device one consisting of a solid foam game module to a reshape essentially cuboid toy building block, would outer surfaces the reshaped toy building block due to its elasticity Bend surfaces outward. Such a game module would not have the desired, essentially cuboid shape, successive game blocks would rock each other due to their convex outer surfaces, a juxtaposition of the game building blocks, for example, a toy wall would not be possible, the toy wall would be no later than three or Collapse four game blocks set on top of each other.

Die DE-C-594 394 offenbart eine Sandform mit zwei durch ein Scharnier gelenkig miteinander verbundenen Formteilen zur Herstellung von freistehenden Sandfiguren. Die Sandform ist an einer Basis offen, so daß eingefüllter Sand unmittelbar auf eine Unterlage aufgesetzt werden und die Sandform anschließend geöffnet und abgenommen werden kann. Zum Umformen plastisch verformbarer Spielbausteine zu im wesentlichen quaderförmigen Spielbausteinen eignet sich die bekannte Sandform ebenfalls nicht.DE-C-594 394 discloses a sand mold with two articulated by a hinge interconnected moldings for the production of freestanding sand figures. The sand mold is open at a base, so that filled sand immediately put on a pad and then the sand mold can be opened and removed. For forming plastically deformable Game building blocks to essentially cuboid game building blocks is suitable the well-known sand mold also not.

Aus der DE-C-286 710 ist eine Spielzeugpresse zum Urformen von Baukastensteinen aus einer feuchten Zementmasse bekannt. Mit der bekannten Spielzeugpresse ließen sich zwar theoretisch aus einem festen Schaum bestehende, plastisch verformbare Spielbausteine zu einem im wesentlichen quaderförmigen Spielbaustein pressen, jedoch würde auch hier das Problem auftreten, daß sich aufgrund einer elastischen Rückformung des Spielbausteins nach seiner Entnahme aus der Spielzeugpresse Außenflächen des Spielbausteins ballig nach außen wölben würden.From DE-C-286 710 is a toy press for primary forming modular blocks known from a moist cement paste. With the well-known toy press could theoretically be made of a solid foam, plastically deformable toy building blocks to a substantially cuboidal Press game block, but also here would be the problem that due to an elastic recovery of the toy building block after its removal out of the toy press outer surfaces of the toy block crowned would bulge outside.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Formgebungsvorrichtung vorzuschlagen, mit der ein Spielbaustein der vorstehend beschriebenen Art zu einem im wesentlichen quaderförmigen Spielbaustein umformbar ist.The invention is therefore based on the object, a shaping device to propose, with a game building block of the type described above a substantially cuboid toy building block is deformable.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Die erfindungsgemäße Formgebungsvorrichtung weist zwei oder mehr Teile auf, die so zusammensetzbar sind, daß die Formgebungsvorrichtung einen im wesentlichen quaderförmigen Innenraum aufweist. Der Innenraum der Formgebungsvorrichtung bildet einen Formgebungsraum, der einen eingelegten, plastisch verformbaren Spielbaustein zu einem Quader oder zumindest näherungsweise zu einem Quader umformt. Dabei sind eine Breite und eine Höhe des Formgebungsraums der zusammengesetzten Formgebungsvorrichtung kleiner als ein Durchmesser des einzulegenden Spielbausteins und eine Länge des Formgebungsraums ist kürzer als eine maximale Länge des einzulegenden Spielbausteins. Vorzugsweise ist ein Volumen des Formgebungsraums kleiner als ein Volumen des einzulegenden Spielbausteins vor dessen Umformung. Beim Einlegen des Spielbausteins in die Formgebungsvorrichtung und beim Schließen der Formgebungsvorrichtung durch Zusammensetzen ihrer Teile übt die Formgebungsvorrichtung Druckkräfte auf den Spielbaustein aus, die diesen zu einem Quader umformen. Zum Zusammensetzen sind die Teile der Formgebungsvorrichtung beispielsweise zusammensteckbar. Es ist auch möglich, die Teile der Formgebungsvorrichtung schwenkbar miteinander zu verbinden. Nach dem Öffnen der Formgebungsvorrichtung und Entnehmen des umgeformten Spielbausteins hat dieser im wesentlichen die Form eines Quaders und läßt sich einfach mit weiteren, ebenfalls quaderförmigen und gleich großen Spielbausteinen beispielsweise zu einer Modellmauer zusammensetzen. This object is achieved by the features of claim 1 solved. The shaping device according to the invention has two or more Parts that are composable so that the molding device a having substantially cuboid interior. The interior of the shaping device forms a shaping space that contains an inserted, plastically deformable toy building block to a cuboid or at least approximately transformed into a cuboid. There are one width and one Height of the molding space of the composite molding apparatus smaller than a diameter of the game module to be inserted and a length of the forming space is shorter than a maximum length of the one to be inserted Toy building brick. Preferably, a volume of the forming space smaller than a volume of the game module to be inserted before it Forming. When inserting the game module in the shaping device and closing the molding apparatus by assembling its Parts exerts the shaping device pressure forces on the game module, the transform this into a cuboid. To assemble the parts are the Shaping device, for example, plugged together. It is also possible, pivotally interconnecting the parts of the molding device. After opening the molding device and removing the reshaped Game building blocks this has essentially the shape of a cuboid and can be easily with other, also cuboid and the same size For example, put toy blocks together to form a model wall.

Einander gegenüberliegende Begrenzungsflächen des Formgebungsraums der Formgebungsvorrichtung sind konvex gewölbt, d. h. einander gegenüberliegende Begrenzungsflächen wölben sich nach innen in den Formgebungsraum hinein. Die Wölbung kann beispielsweise auch durch eine kantige Form nachgeahmt sein. Zweck der konvexen Begrenzungsflächen des Formgebungsraums ist es, ein Rückstellvermögen des Spielbausteins zu kompensieren: Nach dem Umformen formt sich der Spielbaustein aufgrund seiner Elastizität wieder etwas zurück in Richtung seiner ursprünglichen Zylinderform mit balligen Stirnflächen, d. h. eine Außenfläche des Spielbausteins, die von einer ebenen Begrenzungsfläche des Formgebungsraums der Formgebungsvorrichtung umgeformt ist, wölbt sich nach Entnahme des Spielbausteins aus der Formgebungsvorrichtung wieder etwas nach außen. Um diesen Effekt zu kompensieren, wird die Außenfläche des Spielbausteins von der konvexen Begrenzungsfläche des Formgebungsraums in bezug auf den Spielbaustein konkav nach innen gewölbt. Die Rückformung des Spielbausteins nach seiner Entnahme aus der Formgebungsvorrichtung bewirkt dann, daß die von der konvexen Begrenzungsfläche des Formgebungsraums geformte Außenfläche des Spielbausteins nach Entnahme des Spielbausteins aus der Formgebungsvorrichtung in etwa eben ist.Opposing boundary surfaces of the forming space of the Shaping device are convex, d. H. opposite each other Boundary surfaces bulge inward into the shaping space. The curvature can, for example, also imitated by an angular shape be. The purpose of the convex boundary surfaces of the shaping space is To compensate for a recovery of the game module: After forming Because of its elasticity, the toy element forms something again back towards its original cylindrical shape with crowned faces, d. H. an outer surface of the toy building, by a flat boundary surface the shaping space of the shaping device is formed, bulges after removal of the game module from the shaping device again something outward. To compensate for this effect, the outer surface becomes of the toy building block from the convex boundary surface of the shaping space Concave inward curved with respect to the game module. The Recovery of the toy building block after its removal from the molding device then causes the of the convex boundary surface of the Forming space shaped outer surface of the toy building block after removal the toy building block from the shaping device is approximately flat.

Um den Spielbaustein einfach in die geöffnete Formgebungsvorrichtung einlegen zu können, sieht eine Ausgestaltung der Erfindung eine Einlegeschräge vor, die sich an eine Begrenzungsfläche des Formgebungsraums anschließt. Beim Einlegen in die Formgebungsvorrichtung gleitet der Spielbaustein mit einer Stirnfläche oder mit seinem Umfang an er Einlegeschräge entlang und wird dabei axial gestaucht (verkürzt) bzw. in eine Querrichtung gepresst. Die Einlegeschräge erleichtert das Einlegen des Spielbausteins in die Formgebungsvorrichtung. To insert the toy module simply in the open molding device to be able to provide an embodiment of the invention, an insertion beforehand, the adjoins a boundary surface of the shaping space. At the Inserting into the shaping device slides the toy block with an end face or with its circumference at Einlegeschräge along and is axially compressed (shortened) or pressed in a transverse direction. The insertion angle facilitates the insertion of the game module in the shaping device.

Bei einer Weiterbildung der Erfindung weist die Formgebungsvorrichtung jeweils zwei Einlegeschrägen auf, die einander paarweise gegenüberliegend angeordnet sind und die zusammen eine Art Einlegetrichter zum Einlegen des Spielbausteins in die Formgebungsvorrichtung bilden.In a development of the invention, the shaping device in each case two insertion bevels, which are arranged in pairs opposite one another are and together a kind of hopper for inserting the game module form into the shaping device.

Gemäß dem erfindungsgemäßen Verfahren wird ein aus einem festen Schaum bestehender, plastisch verformbarer Spielbaustein mit einer beispielsweise näherungsweise zylindrischen Form in eines der Teile der offenen Formgebungsvorrichtung eingelegt und die Formgebungsvorrichtung wird durch Zusammensetzen ihrer Teile geschlossen. Durch das Zusammensetzen der Teile der Formgebungsvorrichtung übt die Formgebungsvorrichtung Druckkräfte auf den Spielbaustein aus, die diesen zu einem Quader umformen. Einander gegenüberliegende, konvex gewölbte Begrenzungsflächen des Formgebungsraums der Formgebungsvorrichtung formen die an diesen Begrenzungsflächen anliegenden Außenflächen des Spielbausteins konkav nach innen. Aufgrund einer elastischen Rückformung des Spielbausteins nach seiner Entnahme aus der Formgebungsvorrichtung stellen sich die in der Formgebungsvorrichtung konkav nach innen gewölbten Außenflächen des Spielbausteins zu in etwa ebenen Außenflächen zurück. Der Spielbaustein erhält dadurch in etwa ebene Außenflächen, wodurch sich der im wesentlichen quaderförmige Spielbaustein stapeln und sich beispielsweise eine Spielzeugmauer aus den umgeformten Spielbausteinen aufstellen lässt.According to the method of the invention, one is made of a solid foam existing, plastically deformable toy building block with an example approximately cylindrical shape in one of the parts of the open shaping device inserted and the shaping device is by assembling their parts closed. By assembling the parts of the molding device the shaping device exerts compressive forces on the toy building block out, which transform this into a cuboid. Opposite, convex curved boundary surfaces of the forming space of the Forming device form the adjacent to these boundary surfaces Outside surfaces of the play module concave inward. Due to an elastic Recovery of the toy building block after its removal from the molding device the concave in the molding device to the inside curved outer surfaces of the play module to approximately flat outer surfaces back. The game module is replaced by approximately flat outer surfaces, which the essentially cuboid toy building block stack up and, for example set up a toy wall from the transformed play bricks leaves.

This composite state the shaping device 10, 12 is drawn in FIG.

Der Spielbaustein 28 weist sowohl im Durchmesser als auch in seiner axialen Länge ein Übermaß in bezug auf die Formgebungsvorrichtung 10, 12 auf. Beim Einlegen des Spielbausteins 28 in die Formgebungsvorrichtung 10, 12 und beim Zusammensetzen des Oberteils 10 mit dem Unterteil 12, d. h. beim Schließen der Formgebungsvorrichtung 10, 12 wird der Spielbaustein 28 sowohl axial gestaucht als auch in Querrichtung in zwei zueinander senkrechten Richtungen zusammengedrückt. Dadurch wird der Spielbaustein 28 im wesentlichen zu einem länglichen Quader umgeformt.The game module 28 has both in diameter and in its axial Length is an excess with respect to the shaping device 10, 12 on. At the Insertion of the game module 28 in the shaping device 10, 12 and at Assembling the upper part 10 with the lower part 12, d. H. when closing the Shaping device 10, 12, the game module 28 is both compressed axially as well as in the transverse direction in two mutually perpendicular directions pressed together. As a result, the game module 28 is essentially too reshaped an elongated cuboid.

In geschlossenem Zustand der Formgebungsvorrichtung 10, 12 begrenzen deren Ober- und Unterteil 10, 12 einen im wesentlichen quaderförmigen Innenraum zwischen sich, der als Formgebungsraum bezeichnet wird. Die einander gegenüberliegenden konvex gewölbten Oberflächen 15, 24 der Bodenwand 14 des Unterteils 12 und der Deckenwand 20 des Oberteils 10 bilden zwei von sechs Begrenzungsflächen des Formgebungsraums. Diese konvexen Begrenzungsflächen 15, 24 formen an ihnen anliegende Außenflächen des Spielbausteins 28 konkav nach innen (Figur 2). Nach Öffnen der Formgebungsvorrichtung 10 und Entnahme des Spielbausteins 28 formen sich dessen Außenflächen wieder etwas zurück, wodurch die in der geschlossenen Formgebungsvorrichtung 10, 12 konkaven Außenflächen des Spielbausteins 28 im wesentlichen eben werden. Durch diese beiden, einander gegenüberliegenden, im wesentlichen ebenen Außenflächen läßt sich der Spielbaustein 28 mit weiteren, ebensolchen Spielbausteinen 28 einfach beispielsweise zu einer Mauer zusammensetzen. Daß die beiden anderen seitlichen Außenflächen des Spielbausteins 28 sich in folge dessen Rückformverhaltens nach Entnahme aus der Formgebungsvorrichtung 10, 12 konvex nach außen wölben, stört nicht, da an diesen Flächen beim Bau einer Modellmauer keine Spielbausteine 28 angesetzt werden. In the closed state of the shaping device 10, 12 limit their Upper and lower part 10, 12 a substantially cuboid interior between them, which is referred to as a shaping space. The each other opposite convex curved surfaces 15, 24 of the bottom wall 14 the lower part 12 and the top wall 20 of the upper part 10 form two of six Boundary surfaces of the shaping space. These convex boundary surfaces 15, 24 form adjacent outer surfaces of the toy building block 28 concave inwards (Figure 2). After opening the shaping device 10 and Removal of the toy building block 28 forms its outer surfaces again something back, causing the in the closed shaping device 10, 12th concave outer surfaces of the toy building block 28 are substantially flat. Through these two, opposite, essentially flat Outside surfaces can be the game module 28 with more, just such Simply put toy blocks 28 into a wall, for example. That the two other lateral outer surfaces of the toy building block 28 in consequence its reforming behavior after removal from the molding apparatus 10, 12 bulge convexly outward, does not bother, because at these surfaces during construction a model wall no game blocks 28 are set.

Die Einlegeschrägen 18 der Stirnwände 16 können weiter als dargestellt von der Bodenwand 14 wegverlängert und auseinandergezogen werden, um auch längere Spielbausteine 28 einfach in das Unterteil 12 einlegen zu können.The Einlegeschrrägen 18 of the end walls 16 can further than shown by the Bottom wall 14 extended away and pulled apart too longer game blocks 28 easy to insert into the lower part 12.

Da ein lichter Abstand der Stirnwände 16 des Unterteils 12 kleiner als eine axiale Länge des Spielbausteins 28 ist, und der Spielbaustein 28 beim Einlegen axial gestaucht wird, formen die Stirnwände 16 die ursprünglich balligen Stirnflächen des Spielbausteins 28 zu im wesentlichen ebenen Stirnflächen um.Since a clear distance of the end walls 16 of the lower part 12 is smaller than an axial Length of the game module 28 is, and the game module 28 when inserting axially is compressed, the end walls 16 form the originally crowned end faces the game module 28 to essentially flat end surfaces.
