Abstract

A thermoplastic frame produced by an injection moulding process, and used for a planar component, eg a mirror, a glass plate etc, has an open profile at the back and a surface for supporting the component as well as a holding element. The holding element consists of a number of plastic spring members. When the planar component is placed in the frame, it is tensioned as the plastic material cools. ADVANTAGE - The frame is efficient and reliable, and does not require the use of adhesive.

Description

Die Erfindung betrifft einen im Spritzgießverfahren hergestellten Rahmen aus thermoplastischem Kunststoff für einen ebenen Gegenstand, wie Spiegel, Glasscheibe o. dgl., gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an injection molding process manufactured frame made of thermoplastic for one flat object, such as a mirror, glass pane or the like, according to the Preamble of claim 1.

Ein derartiger Rahmen ist durch die DE 36 34 423 A1 bekannt­ geworden. Das am Rahmenprofil angeformte Halteelement, das eine eingelegte Scheibe hintergreift, ist starr ausgebildet. Das Halteelement kann daher nicht durchlaufend, sondern nur stellenweise am Rahmen angeordnet sein, damit die Scheibe durch Auseinanderziehen des Rahmens an den die Halteelemen­ te aufweisenden Bereichen eingelegt werden kann. Eine all­ seitige Halterung der Scheibe ist daher nicht möglich.Such a frame is known from DE 36 34 423 A1 become. The molded on the frame profile holding element engages behind an inserted disc is rigid. The holding element can therefore not continuously, but only be arranged in places on the frame so that the disc by pulling apart the frame on which the holding elements te exhibiting areas can be inserted. An all sided mounting of the disc is therefore not possible.

Das DE-GM 66 06 201 betrifft einen Wechselrahmen, bei dem eine Deckscheibe durch federnde Klammern auf einer Rück­ wand gehalten ist. Ein eigentlicher, die Scheibe umgebender Rahmen ist dort nicht vorhanden.DE-GM 66 06 201 relates to an interchangeable frame in which a cover plate by spring clips on a back wall is held. A real one, surrounding the disc There is no frame there.

Es ist ferner bekannt, Spiegel in Kunststoffrahmen all­ seitig zu befestigen, indem das Spiegelglas in den Rahmen eingeklebt oder durch eine thermische Verformung des Rah­ mens gehalten wird, was sehr arbeits- und kostenintensiv ist.It is also known mirrors in plastic frames all Fasten on both sides by placing the mirror glass in the frame glued or by thermal deformation of the frame mens is kept, which is very labor and cost intensive is.

Der Erfindung liegt die Aufgabe zugrunde, einen Rahmen aus Kunststoff zu schaffen, bei dem eine Scheibe, z. B. ein Spiegelglas o. dgl., mit geringem Montageaufwand und ohne Verwendung von Klebemitteln oder anderen zusätzlichen Hilfs­ mitteln allseitig sicher in dem Rahmen befestigt werden kann.The invention has for its object a framework to create plastic, in which a disc, for. B. a Mirror glass or the like, with little installation effort and without  Use of adhesives or other additional aids are securely attached to the frame on all sides can.

Die Lösung dieser Aufgabe ist im Patentanspruch 1 angegeben.The solution to this problem is specified in claim 1.

Der Kunststoffrahmen gemäß der Erfindung ist montagegünstig und daher mit geringem Arbeitsaufwand herstellbar. Unmittel­ bar nach der Ausformung des Rahmens kann das zu rahmende Glas leicht eingelegt werden. Durch Ausnutzung des ther­ mischen Schwundes legen sich die Kunststoffbiegefedern all­ seitig an das zu rahmende Glas an und halten es sicher, ohne daß zusätzliche Haltemittel herangezogen werden müssen.The plastic frame according to the invention is easy to assemble and therefore can be produced with little effort. Immediately bar after shaping the frame can be framed Glass can be easily inserted. By using the ther Mixing shrinkage, the plastic bending springs all lie down on the side of the glass to be framed and hold it securely without additional holding means having to be used.

In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt.Exemplary embodiments of the invention are shown in the drawing shown.

Fig. 1 zeigt einen Rahmen aus Kunststoff zum Einspannen ei­ nes Glases oder eines Spiegels mittels federnder Halteele­ mente, die als Kunststoffbiegefedern ausgebildet sind. Die Haltebereiche der Kunststoffbiegefedern können verschieden­ artig gestaltet sein. Die Ausführungsform gemäß Fig. 2 zeigt eine hakenförmige Ausbildung des Haltebereiches, während bei der in Fig. 3 dargestellten Biegefeder der Haltebereich zungenförmig ausgebildet ist. Die in Fig. 4 gezeigte Bie­ gefeder weist einen rippenförmigen Haltebereich auf, der bei der Ausführungsform gemäß Fig. 5 noppenförmig ausge­ bildet ist. Fig. 1 shows a frame made of plastic for clamping egg nes glass or a mirror by means of resilient holding elements, which are designed as plastic springs. The holding areas of the plastic bending springs can be designed in different ways. The embodiment according to FIG. 2 shows a hook-shaped design of the holding area, while in the spiral spring shown in FIG. 3 the holding area is tongue-shaped. The spiral spring shown in FIG. 4 has a rib-shaped holding area which is formed in the form of a knob in the embodiment according to FIG. 5.

Zur Montage des Glases im Rahmen wird das Glas unmittelbar nach dem Herausnehmen des Rahmens aus der Spritzgießma­ schine zwischen die Kunststoffbiegefedern eingesetzt. Unter der Wirkung des thermischen Schwundes und des Nachschwun­ des des Rahmens wird das Glas selbstklemmend verspannt. Es wird ohne zusätzliche Maßnahmen, wie Verklebung oder Ultra­ schallschweißung, sicher im Rahmen gehalten, so daß sich mit geringem Arbeitsaufwand eine montage- und kostengün­ stige Rahmung von Glas- oder Spiegelscheiben erreichen läßt.To assemble the glass in the frame, the glass is immediately after removing the frame from the injection molding machine machine inserted between the plastic bending springs. Under the effect of thermal shrinkage and post-shrinkage of the frame, the glass is clamped self-locking. It without additional measures, such as gluing or ultra sound welding, held securely in the frame, so that with little effort, an assembly and cost-effective permanent framing of glass or mirror panes can be achieved.
