B. feinwerktechnischer Geräte ermöglicht ist.The object of the invention is there. in, non-releasable connections in the preamble of claim 1 To improve the specified type so far that while maintaining the state of the art already achieved advantages, which can be seen in the fact that the connection is easy to make, with no structure-borne noise is transferred from one part to the other, also a favorable stability and security is reached, in addition, a further cheaper production is achieved, in particular therefore, because a large-scale production z. B. precision engineering devices is enabled.
Zur Lösung dieser Aufgabe sind bei der Erfindung die im Kennzeichenteil des Anspruches 1 angegebenen Gestaltungsmerkmale vorgesehen, wobei noch im Unteranspruch 2 Vorrichtungsmerkmale zur Durchführung eines Verfahrens zur Herstellung der Erfindung aufgeführt sind.To solve this problem, those specified in the characterizing part of claim 1 are in the invention Design features provided, with device features for implementation in dependent claim 2 a method of making the invention are listed.
Es ist zwar z. B. durch die DE-Gbm-Schrift 17 11 030 bei Verbindungen allgemeiner Art bekanntgeworden, Ausgußmassen auch aus Kunststoff in Verbindungsräume einzubringen, auch im Spritzgußverfahren. Jedoch sind die sonstigen technischen Verhältnisse bei diesem Stand der Technik ganz anders gelagert wie bei der Erfindung.It is z. B. by the DE-Gbm-script 17 11 030 became known for connections of a general kind, pouring compounds also made of plastic in connection spaces to be introduced, also by injection molding. However, the other technical conditions are the same with this one State of the art stored quite differently than in the case of the invention.
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 technischen Hinweise zu erkennen, die dieses Gestaltungsprinzip ohne weiteres und ohne erfinderische Überlegungen entwickeln lassen würden. Vor allem die geschickte Formgestaltung beim Anmeldungsgegcnstand derart, daß sich beim einfachen Anwenden von Kunststoffmaterial, das maschinell aufgebracht wird, eine günstige, sichere, feste Plattenverbindung ergibt, insbesondere eine Verbindung von senkrecht aufeinanderstehenden Platten, ist durch den Stand der Technik nicht nahegelegt worden.For the design principle provided in the invention, consisting of the task and that in the identification part of claim 1 specified solvents are not such technical in the prior art To recognize indications that this design principle easily and without inventive considerations would develop. Above all, the skillful design of the subject of the application in such a way that that with the simple use of plastic material that is applied by machine, a favorable, results in a secure, solid panel connection, in particular a connection between vertically aligned panels Disks, has not been suggested by the prior art.
ίο Die Erfindung hat den Vorteil, daß insbesondere plattenförmige Bauteile einfach und sicher auch in Großserienproduktion miteinander verbunden werden kennen, 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 know, even in compliance with tight tolerances. In addition, the connections can be made by machine an injection molding machine.
Die Merkmale der Erfindung und deren technischen Vorteil" 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 advantage "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 A-Bder 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 Zeichnung nicht dargestellt Die Teile f 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 Durchbräche 3 bzw. 4 sorgen für eine
exakte Lage der miteinander zu verbindenden Teile innerhalb des Werkzeuges während des Spritzvorganges.
F i g. 2 shows a section according to A-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 molding tool is not shown in the drawing. Parts f and 2 are also provided with holes 5 and 6, respectively. The mentioned tool is designed so that during the injection molding process plastic settles along the parts in the form of strips and penetrates the holes 5 and 6, respectively. It thus results in the embodiment according to FIG. 1 an outer strip 7 and on the side of part 2 a U-shaped bar 8 which surrounds the connecting edge of part 2 in a U-shape, the legs 9 and 10 being connected to one another by pieces of material 11. Immediately afterwards, when the parts are connected and come out of the tool, they can be processed further. The openings 3 and 4 ensure an exact position of the parts to be connected within the tool during the injection molding process.
Wie aus der Zeichnung hervorgeht, läßt sich somit in einem Arbeitsgang eine auch komplizierte Verbindung herstellen, die die in der Einleitung aufgezählten Nachteile nicht aufweist. Selbstverständlich ist die 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 F i g. 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 inAs 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. Of course it is Connection 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, 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
bo den Teilen 1 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 ■ s angebracht sein, Abschrägungen vorzunehmen, insbesondere dann, wenn diese Kanten beim Einbau anderer Teile in das Maschinengestell stören würden.Parts 1 and 2 do not have to be, 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 can ■ s be appropriate to make bevels, especially if these edges would interfere with the installation of other parts in the machine frame.
