Description

Zur Beseitigung dieses Nachteils ist es bei solchen größere Wanddicke aufweisen als die Kunststoffhohl-Fenster- und Türrahmen auch bereits bekannt, die profilstäbe. Für die Kunststoffeinsätze kommt vor-Versteifungseinlagen an den Rahmenecken durch zugsweise das gleiche Material wie für die Kunst-Schweißen, Kleben, Nieten und auf ähnliche geeigne- stoffhohlprofilstäbe in Frage, zumindest aber ein te Weise fest miteinander zu verbinden. Hierdurch 55 Kunststoff, der sich mit dem der Kunststoffhohlproergeben sich jedoch insofern beträchtliche Schwierig- filstäbe gut verschweißen läßt. Als besonders vorteilkeiten, als entweder die Versteifungseinlagen vor der haft hat sich ein für diesen Zweck bereits bekanntes Umhüllung mit Kunststoff an den vier Rahmenecken und verwendetes schlagfestes Hart-PVC bewährt,

Dies filstäbe 1 nur bis kurz vor die Rahmenecke 4 geführt bedeutet einen erheblichen Arbeitsaufwand und be- und mit Kunststoffeinsätzen 3 versehen, die bis in die dingt den Einsatz komplizierter Schweißgeräte, deren 65 Ecke 4 reichen. Zur Fertigstellung des Rahmens wer-Schweißspiegel beim Verschweißen der Kunststoff- den die einzelnen Kunststoffhohlprofilstabe 1 mit den hohlprofilstäbe nicht mit dem Einlagerahmen aus darin eingeschobenen Versteifungseinlagen 2 und den Metall od. dgl. in Berührung kommen darf. endseitig eingesetzten Kunststoffeinsätzen 3 in einemTo eliminate this disadvantage, it is already known that the profile rods have a greater wall thickness than the plastic hollow window and door frames. For the plastic inserts, pre-stiffening inserts at the frame corners by preferably the same material as for the art-welding, gluing, riveting and similar suitable hollow profile rods come into question, but at least to be firmly connected to one another. As a result, plastic, which can, however, be welded well to that of the hollow plastic samples, which are considerably difficult to this extent. As a particular advantage, as either the stiffening inserts in front of the detention, a plastic coating on the four frame corners and used impact-resistant hard PVC, which is already known for this purpose, has proven itself,
be connected to form a rigid unit in itself. An embodiment of the subject matter of the must, in order to subsequently find a suitable multi-part 60 invention is shown in the drawing.
As can be seen in the drawing, the stiffening frames are to be pushed on and also welded to one another on the frame stiffening inserts 2 within the plastic hollow profiles. This filststab 1 only led to just before the frame corner 4 means a considerable amount of work and loaded and provided with plastic inserts 3, which include the use of complicated welding devices, the corner 4 of which extend. To complete the frame, the individual plastic hollow profile rods 1 with the hollow profile rods must not come into contact with the insert frame made of stiffening inserts 2 and the metal or the like when welding the plastic. plastic inserts 3 inserted at the end in one

Only the plastic hollow profile rods 1 and the plastic inserts 3 welded together as also from the Zeichnung zu erkennen, sind die Kunststoffeinsätze 3 als Hohlprofile ausgebildet, und zwar im vorliegenden FaUe als Vierkant-Hohlproffle, die eine größere Wanddicke als die Kunststoffhohlproiilstäbe 1 haben.The drawing shows the plastic inserts 3 designed as hollow profiles, namely in the present FaUe as square hollow profile, which is a larger Wall thickness than the plastic hollow profile rods 1 have.

Mitred fabric inserts together with the plastic hollow profile rods in one work step are cut and welded.

This means that the previously required separate frame production for the stiffening insert made of metal is no longer necessary.

In a known plastic hollow profile frame are brought up and give a sufficient with stiffening insert made of metal (German Ge strength and torsional stiffness, while the utility model 1 965 389), the plastic hollow plastic inserts have this function only in the Profile rods at the frame corners have to be filled with 40 welded frame corners. As the plastic feet firmly connected to each other, while the end inserts are not only connected to each other during welding inclined stiffening inserts are only given away with the plastic hollow profile rods support each other. Such an execution weld results in a particularly stiff one form has the disadvantage, however, that the corner connection, which meets all practical requirements 45 compared to the stiffened plastic hollow pro- 45 is sufficient.
