Für das bei der Erfindung vorgesehene Gestaltungsprinzip, bestehend aus Aufgabe und den im Kennzeichenteil des Anspruches 1 angegebenen Lösungsmitteln sind beim Stand der Technik keine solchen technische«! Hinweise zu erkennen, die dieses Gestaltungsprinzip ohne weiteres und ohne erfinderische Überlegungen entwickeln lassen würden. Vor allem die geschickte Formgestaltung beim Anmeldungsgegenstand derart daß sich beim einfachen Anwenden von Kunststoffmaterial, das maschinell aufgebracht wird, eine günstige, sichere, feste Plattenverbindung ergibt insbesondere eine Verbindung von senkrecht aufeinanderstellenden Platten, ist durch den Stand der Technik nicht nahegelegt worden.For the design principle provided in the invention, consisting of the task and the solvents specified in the characterizing part of claim 1 are in the state of the art no such technical «! Notes to recognize that this design principle can be developed without further ado and without inventive considerations. Above all the clever ones Shaping the subject of the application in such a way that when simply using plastic material, which is applied by machine, in particular, results in an inexpensive, secure, solid panel connection a connection of perpendicularly stacked panels is not supported by the prior art been suggested.
ίο Die Erfindung hat den Vorteil, daß insbesondere plattenförmige Bauteile einfach und sicher auch in Großserienproduktion miteinander verbunden werden können, auch unter Einhaltung enger Toleranzen. Außerdem können die Verbindungen maschinell mittels einer Spritzgußmaschine erfolgen.ίο The invention has the advantage that in particular Plate-shaped components can be connected to one another easily and safely, even in large-scale production can, even while maintaining tight tolerances. In addition, the connections can be made by machine an injection molding machine.
Die Merkmale der Erfindung und deren technischen Vorteile ergeben sich auch aus der nachfolgenden Beschreibung eines Ausführungsbeispieles in Verbindung mit den Ansprüchen und der Zeichnung. Es zeigtThe features of the invention and its technical advantages also emerge from the following Description of an embodiment in connection with the claims and the drawing. It shows
F i g. 1 die Verbindung zweier Teile, teilweise im Schnitt undF i g. 1 the connection of two parts, partly in section and
F i g. 2 einen Schnitt nach Λ-B der F i g. 1.
Im Ausführungsbeispiel nach F i g. 1 ist das eine Teil eine abgewinkelte Metallplatte 1 und das andere Teil
eine flache Platte 2. Diese beiden Teile sollen miteinander verbunden werden. Die Teile 1 und 2 sind
mit Durchbrüchen 3 bzw. 4 versehen, die dazu dienen, lagegesichert in ein Spritzwerkzeug eingesetzt zu
werden. Dieses Spritzwerkzeug ist auf der ZeichnungF i g. 2 shows a section according to Λ-B of FIG. 1.
In the embodiment according to FIG. 1, one part is an angled metal plate 1 and the other part is a flat plate 2. These two parts are to be connected to one another. The parts 1 and 2 are provided with openings 3 and 4, respectively, which are used to be inserted in a secured position in an injection molding tool. This injection tool is on the drawing
jo nicht dargestellt Die Teile 1 und 2 sind außerdem mit Löchern 5 bzw. 6 versehen. Das erwähnte Werkzeug ist so ausgebildet daß sich während des Spritzvorgangs Kunststoff leistenförmig entlang der Teile absetzt und dabei die Löcher 5 bzw. 6 durchdringt Es ergibt sich somit beim Ausführungsbeispiel nach F i g. 1 eine Außenleiste 7 und auf der Seite des Teiles 2 eine U-förmige Leiste 8, die die Verbindungskante des Teiles 2 U-förmig umgreift wobei die Schenkel 9 und 10 durch Materialstücke 11 miteinander verbunden sind. Sofort danach, wenn die Teile verbunden sind und aus dem Werkzeug kommen, können sie weiterverarbeitet werden. Die Durchbrüche 3 bzw. 4 sorgen für eine exakte Lage der miteinander zu verbindenden Teile innerhalb des Werkzeuges während des Spritzvorganges. jo not shown The parts 1 and 2 are also with Provide holes 5 and 6 respectively. The mentioned tool is designed so that during the spraying process Plastic strips down along the parts and thereby penetrates the holes 5 and 6, respectively thus in the embodiment according to FIG. 1 an outer strip 7 and on the side of part 2 one U-shaped bar 8, which engages around the connecting edge of part 2 in a U-shape, the legs 9 and 10 through Pieces of material 11 are connected to one another. Immediately afterwards, when the parts are connected and out of the When the tool arrives, they can be processed further. The openings 3 and 4 provide a exact position of the parts to be connected within the mold during the injection molding process.
Wie aus der Zeichnung hervorgeht, läßt sich somit in einem Arbeitsgang eine auch komplizierte Verbindung herstellen, die die m der Einleitung aufgezählten Nachteile nicht aufweist Selbstverständlich ist dieAs can be seen from the drawing, a complex connection can be made in one operation produce that does not have the disadvantages listed in the introduction
so Verbindung nicht auf das dargestellte Ausführungsbeispiel beschränkt Die Verbindung kann mit gleichen Vorteilen z. B. auch dort verwendet werden, wo zwei Teile nicht winkelförmig miteinander verbunden werden müssen. Je nach der Ausbildung des Spritzwerkzeuges können bei einem Werkstück nach Fig. 1 die Verbindungen in einem oder in zwei Arbeitsgängen durchgeführt werden. Dies hängt nicht zuletzt auch von der Größe der miteinander zu verbindenden Teile und damit den Werkzeugkosten ab. Die Löcher 5 bzw. 6 inso connection is not limited to the illustrated embodiment. The connection can be with same Advantages z. B. can also be used where two parts are not connected at an angle have to. Depending on the design of the injection molding tool, in the case of a workpiece according to FIG. 1, the Connections can be carried out in one or two operations. Last but not least, this also depends on the size of the parts to be connected and thus the tool costs. The holes 5 and 6 in
eo den Teilen f und 2 müssen auch nicht, wie dargestellt, rund sein. In besonderen Fällen mag es vorteilhaft sein, sie drei- oder mehrkantig auszubilden oder ihnen sonst eine zweckmäßige Form zu geben. Im Bereich der Kanten 12 oder 13 der U-förmigen Schenkel 9 und 10 kann es angebracht sein, Abschrägungen vorzunehmen, insbesondere dann, wenn diese Kanten beim Einbau anderer Teile in das Maschinengestell stören würden.eo parts f and 2 do not have to, as shown, be round. In special cases it may be advantageous to make them triangular or polygonal or otherwise to give it an expedient form. In the area of the edges 12 or 13 of the U-shaped legs 9 and 10 it may be appropriate to make bevels, especially if these edges are being installed other parts in the machine frame would interfere.
