Abstract

The invention relates to embedding protective glasses for explosion-protected lighting fittings, and is applied when mounting the protective glass in the glass holder in a manner free from stress. The aim is to eliminate the indicated disadvantages of the known embedding method. It is the object of the invention to simplify the design of the components, to reduce them to a minimum number and to produce an embedding of the protective glass that is free from stress with the use of domestic raw materials. A narrow-flanged protective glass is situated in a recess of a metal ring, and is sealed by means of a mixture of hardenable, inorganic media. The recess of the metal ring has a slanted shape on its side averted from the protective glass. The ratio of the inorganic media is selected so as to ensure stress-free embedding of the protective glass in the axial and horizontal direction, as well as non-destructive materials testing. <IMAGE>

Description

Titel der Erfindung: Title of the invention:

Einbettung von Schutzgläsern für explosionsgeschutzte Leuchten Anwendungsgebiet der Erfindung: Die Erfindung findet Anwendung in explosionsgeschutzten Leuchten zur Herstellung einer spannungsfreien Verbindung zwischen Schutzglas und Glashaltering, vorzugsweise zur Herstellung der drucKfesten Kapselung des Lampenraumes. Embedding of protective glasses for explosion-proof lights. Application area of the invention: The invention is used in explosion-proof lights to create a tension-free connection between protective glass and glass retaining ring, preferably for producing the pressure-resistant encapsulation of the lamp compartment.

Charakteristik der bakannten technischen Lösungen: Es wurde bereits ein Einbettungssystem vorgeschlagen, in dein unter Verwendung von Metallringen mit Gewindeverbindungen das Schutzglas gegen seinen Breitflansch angepreßt wird. Characteristic of the known technical solutions: It was already Suggested an embedding system in your using metal rings with Threaded connections the protective glass is pressed against its wide flange.

Dieses System hat den Nachteil, daß es materialmäßig sehr aufwendig ist, einen hohen Arbeotszeitaufeand erfordert und das Schutzglas einen breitflächigen, plan- Nachteil ist, daß derartig angewendete Medien, z. B. This system has the disadvantage that it is very expensive in terms of material is, requires a long work time and the protective glass has a wide, plan- The disadvantage is that media used in this way, e.g. B.

Blei, materialmäßig sehr kostenaufwendig sind und eine unumgängliche, zeitaufwendige a':rmebehandlung erfordern. Lead, are very expensive in terms of material and an unavoidable, require time-consuming a ': rme treatment.

Ferner ist nachteilig, daß Schutzglaseinfassungen aus Leichtmetallenm z. B. Aluminiumgußlegierungen, wegen zur zu überbrückenden unterschiedlichen Ausdehnungskoef @iz enten von Glas und ketall nicht einsetzbar sind, sodaß andere Metalle, z. B. Graugußelemente, notwendig sind, die sich auf das Gewicht der Beleuchtungskörper negativ auswirken.Another disadvantage is that protective glass surrounds made of light metals z. B. aluminum alloys, because of the different expansion coefficients to be bridged @iz ducks of glass and ketall cannot be used, so that other metals such. B. Cast iron elements, which are necessary to the weight of the lighting fixture, are necessary have a negative impact.

Ziel der Erfindung: Das Ziel der Erfindung besteht darin, die aufgezeigten Nachteile der bekannten Einbettungsverrfahren zu beseitigen und die bisher verwendeten Schwerpunktmaterialien abzubauen. Aim of the invention: The aim of the invention is to achieve those indicated To eliminate the disadvantages of the known embedding processes and those previously used Dismantle focus materials.

Darlegung des eisens der L?rfindung: Die Aufgabe der Erfindung besteht darin, die Bauteile konstruktiv zu vereintacaen, auf eine minimale Anzahl zu reduzieren und eine spannungsfreie Einbettung des Schutzglases unter Verwendung-einheimischer Rohstoffe und ALaterialien zur Erreichung des druckfest gekapselten lampenraumes zu erzielen. Statement of the iron of the invention: The object of the invention is in combining the components constructively, reducing them to a minimum number and a stress-free embedding of the protective glass using indigenous Raw materials and materials to achieve the flameproof lamp compartment to achieve.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß in einem Metallring eine Aussparung eingearbeitet ist, in die ein schmalflanschiges Schutzglas eingelegt wird.According to the invention this object is achieved in that in a metal ring a recess is incorporated into which a narrow-flanged protective glass is inserted will.

die Aussparung enthalt-an seiner dem Schutzglas abgewandten Seite eine Formschräge.contains the recess on its side facing away from the protective glass a draft.

Die Neigung der Formschräge ist so ausgelegt, daß eine ausreichende Festigkeit der Baueinheit Schutzglas/Metallring gewährleistet ist, die im Falle einer stattfindenden Explosion im Lampemraum notwendig ist. The inclination of the draft is designed so that a sufficient Strength of the structural unit protective glass / metal ring is guaranteed in the event an explosion taking place in the lamp room is necessary.

Die Aussparung wird nach eingesetztem schutzgas mit anorganischen Medien ausgegossen und ausgehärtet.The recess is filled with inorganic gas according to the inert gas used Media poured out and cured.

Das Verhältnis der anorganischen Medien ist so gewählt, daß die Kombination Schutzglas/llSetallri/anorganische Medien eine spannungsfreie Einbettung des Schutzglases in axialer und horizontaler Richtung ermöglicht und eine zerstörungsfreie Werkstoffprüfung (statische Druckprüfung) gewährleistet ist.The ratio of the inorganic media is chosen so that the combination Protective glass / llSetallri / inorganic media a stress-free embedding of the protective glass in the axial and horizontal direction and enables non-destructive testing of materials (static pressure test) is guaranteed.

Ausfu"hrungsbeispiel: Ein Metallring 1 enthält eine Aussparung, in die das Schutzglas 2 eingelegt wird. Aussparung 3 enthält eine auf seiner dem Schutzglas 2 abgewendeten Seite eine Formschräge 4. Die Aussparung 3 des Metallringes mit dem eingelegten Schutzglas 2 ist durch ein Gemisch von anorganischen, aushärtbaren Medien 5 ausgefüllt und ergibt die starre Verbindung der Kombination Metallring/Schutzglas.Exemplary embodiment: A metal ring 1 contains a recess in which the protective glass 2 is inserted. Recess 3 contains one on its the protective glass 2 side facing away from a bevel 4. The recess 3 of the metal ring with the inserted protective glass 2 is through a mixture of inorganic, hardenable media 5 filled in and results in the rigid connection of the metal ring / protective glass combination.
