Abstract

In a connection, by means of which two parts consisting of rigid material of a single-part article, e.g. a letter file, are connected to each other in an articulated manner in such a way that the article has a smaller wall thickness in the region of the articulation-type connection than in the remaining region of the article, there is not only the risk that a film applied to the articulation point or a strip of fabric or even a sheet of paper laminated onto the article on one or both sides will become detached at the articulation point, but there is also the risk of a non-precise position of the articulation axis, with the result that the parts thus connected to each other become distorted relative to each other and, for example, a letter file having two such articulation points bounding the rear part tends to tip over in the filled state. This disadvantage is avoided according to the invention in that an articulation point has two articulation webs (1, 2) having a reduced thickness at least partially in relation to the wall thickness of the two parts (3, 4), the two webs (1, 2) advantageously having constrictions (11, 12; 21, 22) at their two longitudinal ends parallel to the articulation axis. <IMAGE>

Description

Die Erfindung betrifft eine einstückige gelenkartige Verbindung zweier aus biegesteifem Material bestehender Teile der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a one-piece joint-like connection of two made of rigid material Parts of the genus specified in the preamble of claim 1.

Gelenkverbindungen dieser Art werden bei aus Pappe hergestellten Gegenständen meist durch zwei Prägerillen gebildet, deren verminderte Wandstärke eine verminderte Biegesteifigkeit zur Folge hat. Die Verwindungssteifigkeit eines solchen Gelenks ist jedoch verhältnismäßig gering, so daß beispielsweise gefüllte Briefordner zum Kippen neigen und die Kanten des Vorderdeckels bei geschlossenem Briefordner schräg zu den Kanten des die Aufreihvorrichtung tragenden rückwärtigen Deckels verlaufen. Auch weisen solche Gelenkverbindungen nur eine geringe Stoßfestigkeit auf. Auch besteht bei solchen Briefordnern die Gefahr, daß ein zur Verstärkung der Gelenkstellen auf diese aufgebrachter Leinwandstreifen oder ein auf die aus Pappe bestehenden Deckel aufkaschierter, Muster aufweisender Papierbogen sich an den Gelenkstellen löst.Articulated connections of this type are usually created by two embossed grooves in objects made of cardboard formed, the reduced wall thickness of which results in reduced flexural rigidity. The torsional stiffness such a joint is relatively small, so that, for example, filled Tilt the letter folder and tilt the edges of the front cover when the letter folder is closed the edges of the rear cover carrying the stringing device run. Such articulated connections also have only has a low impact resistance. With such letter folders there is also the risk that a canvas strip applied to the joint to reinforce the joints or one made of cardboard Existing cover of laminated paper sheets showing patterns loosens at the hinge points.

Dieselben Nachteile weisen auch Briefordner auf, deren Vorderdeckel, der Rücken und der rückwärtige Deckel aus Kunststoff gefertigt sind und deren Gelenkverbindungen in gleicher Weise die Materialstärke verringernde, die Gelenkstellen bildende Rillen aufweisen.The same disadvantages also have letter folders, their front cover, the spine and the rear cover Lids are made of plastic and their articulated connections reduce the material thickness in the same way, have grooves forming the hinge points.

Diese Nachteile werden gemäß der Erfindung durch Gelenkverbindungen vermieden, die die im Kennzeichen des Hauptanspruchs angegebenen Merkmale aufweisen. Vorteilhafte Ausgestaltungen solcher Gelenkverbindungen ergeben sich aus den Unteransprüchen.These disadvantages are avoided according to the invention by articulated connections that are shown in the characterizing part of the main claim have specified features. Advantageous configurations of such articulated connections result from the subclaims.
