ι Diapositiv-Rahmen aus Kunststoffι Slide frame made of plastic
Die Neuerung bezieht sich auf einen Diapositiv-Rahmen aus Kunststoff, der exnen mit einem ringsum laufenden Rand versehenen Rahmenteil und einen innerhalb des Rahmens eingebetteten, al<3 flacher Deckel ausgebildeten Rahmenteil aufweist, die mittels eines Filmscharniers miteinander verbunden sind.The innovation relates to a slide frame made of plastic, which is provided with an all-round edge on the outside Frame part and a frame part embedded within the frame, designed as a <3 flat cover, which are connected to one another by means of a film hinge are.
Bei einem bekannten Diapositiv-Rahmen dieser Art weist das Filmscharnier über einen bestimmten Bereich einen gleichförmigen Querschnitt auf und ist der erwarteten Ausbeulung entgegengesetzt gebogen. Das hat den Nachteil, daß im Spritzgießwerkzeug in beiden Formteilen formgebende Konturen eingearbeitet werden müssen, was die Herstellung wesentlich verteuert. Außerdem ist eine hohe Präzision bei der Zentrierung der beiden Formhälften zueinander nötig. Schon ein geringer Versatz der Formhälften zueinander würde die Wirkungsweise des Scharniers beeinträchtigen.In a known slide frame of this type, the film hinge has a uniform over a certain area Cross-section and is curved in the opposite direction to the expected bulge. This has the disadvantage that in the injection mold Shaping contours have to be incorporated into both molded parts, which makes production considerably more expensive. In addition, a high level of precision is required when centering the two mold halves with respect to one another. Already a little Misalignment of the mold halves with respect to one another would impair the effectiveness of the hinge.
Der Neuerung liegt dia Aufgabe zugrunde, unter Vermeidung der geschilderten Nachteile eine Scharnier-Ausbildung vorzugschlagen, die eine schnellere und billigere Produktion von Diapositiv-Rahmen ermöglicht.The innovation is based on the task, avoiding it of the disadvantages outlined to propose a hinge training that is faster and allows cheaper production of slide frames.
Die Lösung der gestellten Aufgabe besteht darin» daß der Rücken des Filmscharniers neuerungsgemäß plan ausgebildet ist. In weiterer Ausgestaltung der Erfindung weist die Innenseite des Filmscharniers zwei Knicklinien auf, entlang welcher die Stärke des Filmscharniers etwa 0,2 mm beträgt, die Materialaussparung zur Bildung rler Knicklinien jeweils rechtwinklig ausgebildet i^t und zwischen den Knicklinien eine vorzugsweise dreieckförmige Materialanhäufung angeordnet ist, so daß bei geschlossenem Scharnier die Flanken der Materialanhäufung und die Flanken der Mate.rialaussparung zur Anlage kommen. Die Stärke des Filmscharniers im Bereich der Knicklinien soll so dünn sein, daß der Rücken des Scharniers möglichst scharfe Knickstellen bzw. Kanten erhält. Dadurch, daß der Rücken des Filmscharniers plan ausgebildet ist, kann ein Formteil des Spritzgießwerkzeugs ohne Einarbeitung von formgebenden Konturen bleiben. Infolgedessen entfällt auch die Notwendigkeit einer Zentrierung der beiden Formhälfter». zueinander. Zudem ist es einfacher, beim Spritzen der Rahmen das Material durch die beiden Engpässe, die durch die Knicklinien gebildet sind, hindurchzuspritzen, da die verengten Durchlässe sehr kurz sind und zwischen ihnen wiederum eine Verbreiterung des Durchlaßkanals für das Material liegt.The solution to the task at hand consists in the fact that the back of the film hinge is newly designed to be flat is. In a further embodiment of the invention, the inside of the film hinge has two crease lines along which the thickness of the film hinge is about 0.2 mm, the material recess for Formation of kink lines is formed at right angles and one preferably between the kink lines triangular accumulation of material is arranged, so that when the hinge is closed, the flanks of the Accumulation of material and the flanks of the material recess come into contact. The strength of the film hinge in the area of the crease lines should be so thin that the back of the hinge should be as sharp as possible or edges received. Because the back of the film hinge is flat, a molded part can of the injection molding tool without the incorporation of shaping contours. As a result, it is not applicable also the need to center the two mold halves ». to each other. It is also easier to do with the Inject the frame the material through the two bottlenecks that are formed by the kink lines, to inject through, since the narrowed passages are very short and between them again a widening of the passage for the material.
Einzelheiten der Neuerung ergeben sich aus den beiden hinterlegten Modellen eines Ausführurgsbeispiels derDetails of the innovation emerge from the two stored models of an exemplary embodiment of the
Neuerung im Format 110 mm. Selbstverständlich läßt sich die Neuerung aber auch bei Diapositiv-Rahmen anderer Formate verwirklichen, z.B. 124 mm oder 13 6 mm. Ferner kann das Scharnier nach der Neuerung auch für Diapositiv-Rahmen Verwendung finden, deren zu verbindende Rahmenteile nicht aus einem Rahmenteil mit einem ringsum laufenden Rand und einem Deckelteil bestehen.New in the 110 mm format. Of course, the innovation can also be used with slide frames realize other formats, e.g. 124 mm or 13 6 mm. Furthermore, according to the innovation, the hinge can also be used for slide frames Frame parts to be connected do not consist of a frame part with an all-round edge and a Cover part exist.
