Abstract

Die Erfindung betrifft ein linear bewegliches, offenes Scharnier fuer Zwischenstellenbehaelter der drahtgebundenen Nachrichtentechnik. Das kostenguenstige Scharnier zum Aufklappen des Behaelterdeckels bei Montage und Servicearbeiten soll sich durch hohe Funktionssicherheit auszeichnen und ein Beruehren des Behaelterdeckels mit dem Fussboden verhindern. Erfindungsgemaess wird dies dadurch erreicht, dass das Scharnier aus zwei paarweise angeordneten und aus Halbzeug gebogenen Oesen besteht, die an der Unterseite des Montageflansches des Behaeltertopfes fest verbunden sind und dass beim Umklappen des Behaelterdeckels um diese Oesen jeweils ein Haken mit einer Stuetznase drehen, die in einem Flansch am Deckelrand fest und senkrecht zu diesem montiert sind und vertikal durch die waagerecht angeordneten Oesen greifen. Fig. 1The invention relates to a linearly movable, open hinge for Zwischenstellenbehaelter the wired telecommunications. The cost-effective hinge for unfolding the container lid during assembly and service work should be characterized by high reliability and prevent touching the container lid with the floor. This is achieved according to the invention in that the hinge consists of two eyelets arranged in pairs and bent from semifinished product, which are fixedly connected to the underside of the mounting flange of the container pot and in that, when the container lid is folded around these eyelets, a hook with a support nose rotates a flange on the lid edge are fixed and mounted perpendicular to this and vertically through the horizontally arranged eyelets.

Gemäß Fig. 1 besteht das erfindungsgemäße Scharnier für beispielsweise einen PCM-Zwischenstellenbehäiter aus der Öse 1, die vorzugsweise aus dem Halbzeug Runddraht gebogen ist und als ein Paar an der Unterseite des Montageflansches 2 des Behältertopfes 3 der unbemannten Zwischenstelle der Nachrichtenübertragungsanlage angeschweißt ist. In dem Montageflansch 2 des Behältertopfes 3 sind in Abständen und senkrecht zur Oberseite des Montageflansches 2 die Stehbolzen 4 geschraubt, die zur Befestigung des Behältertopfes mit dem Flansch 5 des Behälterdeckels 6 dienen.1, the hinge according to the invention for example, a PCM Zwischenstellenbehäiter from the eyelet 1, which is preferably bent from the semi-finished round wire and welded as a pair on the underside of the mounting flange 2 of the container pot 3 of the unmanned intermediate point of the communication system. In the mounting flange 2 of the container pot 3, the stud bolts 4 are screwed at intervals and perpendicular to the top of the mounting flange 2, which serve for fastening the container pot with the flange 5 of the container lid 6.

In dem Flansch 5 des Behälterdeckels 6 sind zwei der vertikalen Haken 7, der einerseits mittels der Schraubverbindung 8 fest verbunden und andererseits in der etwas nach außen versetzten Bohrung 9 des Flansches 5 arretiert ist, mit dem Bogenstück nach unten montiert.In the flange 5 of the container lid 6 are two of the vertical hook 7, which is firmly connected on the one hand by means of the screw 8 and on the other hand locked in the slightly outwardly offset bore 9 of the flange 5, mounted with the elbow down.

Die Haken 7 greifen mit dem inneren Schenkel durch die horizontal zu ihnen angeordneten Ösen 1. An den gleichen Schenkel der Haken 7 ist die Stütznase 10, mit ihrer Öffnung zum Bogenteil des Hakens 7 gerichtet, geschweißt.The hooks 7 engage with the inner leg through the eyelets arranged horizontally to them 1. At the same leg of the hook 7, the support nose 10, directed with its opening to the bow portion of the hook 7, welded.

Zum Öffnen des Zwischenstellenbehälters werden die Mutter von den Stehbolzen 4 geschraubt und der Behälterdeckel 6 gemäß Fig. 2 vom Behältertopf 3 abgehoben und dabei axial versetzt. Dabei werden die Ösen 1 mit der Stütznase 10 der beiden Haken 7 bei Absenken des Behälterdeckels 6 arretiert. Danach kann der Behälterdeckel 6 durch das somit geschaffene linear bewegliche, offene Scharnier des Zwischenstellenbehälters problemlos gemäß Fig. 3 geklappt werden, ohne daß dabei eine Berührung des Behälterdeckels 6 mit dem Erdboden erfolgt.To open the intermediate container, the nut are screwed by the stud bolts 4 and the container lid 6 lifted as shown in FIG. 2 from the container pot 3 while axially displaced. The eyelets 1 are locked with the support nose 10 of the two hooks 7 when lowering the container lid 6. Thereafter, the container lid 6 can be easily folded by the thus created linearly movable, open hinge of the intermediate container according to FIG. 3, without causing a contact of the container lid 6 takes place with the ground.

Bei Umkehrung des Klappvorganges wird das erfindungsgemäße Scharnier in seiner Wirkung aufgelöst und die Ausgangslage des Behälterdeckels 6 erreicht.Upon reversal of the folding process, the hinge according to the invention is dissolved in its effect and reaches the initial position of the container lid 6.

Durch Einsatz von billigen Halbzeugen und Verwendung von kostruktiv einfachen Teilen beim erfindungsgemäßen Scharnier ist eine kostengünstige Herstellung und eine hohe Funktionssicherheit gesichert.The use of cheap semi-finished products and the use of structurally simple parts in the hinge according to the invention ensures cost-effective production and high functional reliability.

Claims

Linearly movable, open hinge for interground container of the wired communications technology, which consists of container pot and container lid and is suitable for both earth and shaft installation, characterized in that two paired eyelets (1) fixed to the underside of the mounting flange of the container pot, on the the stud bolts are screwed to attach the container lid, are connected and that when folding the container lid around these eyelets each rotate a hook (7) with a support lug (10) mounted in a flange (5) fixed to the container lid edge and perpendicular thereto are vertical and reach through the horizontally arranged eyelets.

Field of application of the invention

The invention relates to a linearly movable, open hinge for unmanned interposition container of telecommunications.

Characteristic of the known technical solutions

It is known from DD-WP 225309 a modern intermediate station container for telecommunications, which consists of a pot-like vessel with a lid. This unmanned intermediate station container is used to hold regenerator amplifiers and other electronic components of the wired communications technology. These assemblies must be accessible from the outside during installation, maintenance and repair regardless of the application of the intermediate station, the earth burial or the shaft installation. The lid of the container is to be detached from the container pot. The user is required by a modern intermediate container that its lid can be hinged without touching the ground to avoid contamination. Such demands are previously known only from containers of power engineering. Their hinges are linearly adjustable via column guides. They consist of a fork and a pin. By means of a pin fork and pins are connected to each other, whereby the joint is made for the container. Such a hinge point and the column guide require in their manufacture a high workload and high demands in terms of manufacturing accuracy. Furthermore, these hinges are susceptible to dirt and corrosion phenomena. They are therefore unsuitable for use in telecommunications intermediate storage containers.

Object of the invention

The object of the invention is a low-cost hinge for unfolding the intermediate container in unmanned public broadcasting offices of the telecommunications, which is characterized by high reliability and reliability.

Explanation of the essence of the invention

The object of the invention is therefore to provide a suitable for the earth or shaft installation of the intermediate container and insensitive to contamination hinge, which allows both a linear movement and a pivoting of the container lid, with any ground contact of the container lid are excluded. According to the invention this object is achieved in that the linearly movable and open hinge consists of two paired and bent from suitable round wire eyelets, which are firmly connected to the underside of the mounting flange of the container pot on which the locking pins are screwed for fastening the container lid, and that in each case a hook with a support nose rotates when folding the container lid around these eyelets. The hooks are fixed in a flange on the edge of the lid and mounted perpendicular to this and reach vertically through the horizontally arranged eyelets.
