Description

Gehäuse für ein Gerät der Unterhaltunqselektronik Housing for a device of entertainment electronics
Gehäuse für Geräte der Unterhaltungselektronik wie z.B. Fern¬ sehempfänger, Lautεprecherboxen und Racks bestehen vorzugs¬ weise aus mehreren Platten, die an den Kanten zusammenge¬ setzt sind. Vorzugsweise werden dafür Spanplatten mit einer Stärke von etwa 10 mm verwendet. • Die Spanplatten werden mit einer Folie entsprechend dem gewünschten Design versehen, z.B. Nußbaum, Teak, Palisander, wobei die Folie vorzugsweise ohne Unterbrechung die jeweiligen Ecken des Gehäuses über¬ spannt.Housings for consumer electronics devices such as television receivers, loudspeaker boxes and racks preferably consist of several plates which are assembled at the edges. Chipboard with a thickness of approximately 10 mm is preferably used for this. • The particle boards are provided with a film according to the desired design, for example, walnut, teak, rosewood, wherein the film preferably without interruption, the respective corners of the housing über¬ biases.
Der Erfindung liegt die Aufgabe zugrunde, für derartige Plat¬ ten für ein. Gehäuse ein neuartiges Material anzugeben, das Vorteile in verschiedener Hinsicht, insbesondere bezüglich der Herstellung, des Gebrauchs und der Sicherheit aufweist.The invention is based, for such plates for a . Provide housing a novel material that has advantages in various respects, particularly in terms of manufacture, use and safety.
Diese Aufgabe wird durch die im Anspruch 1 beschriebene Er¬ findung gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.This object is achieved by the invention described in claim 1. Advantageous developments of the invention are described in the subclaims.
Grundsätzlich können Spanplatten oder Faserplatten verwendet werden, die Bestandteile aus Gips oder Zement enthalten. Der¬ artige Platten sind bekannt unter anderem als Gipsfaserplat¬ ten, zementgebundene Holzspanplatten (Duripanel), gipsgebun¬ dene Spanplatten und Gipsspanplatten. Gipsεpanplatten und Gipsfaserplatten bestehen aus Zellulose mit Gips als Binde¬ mittel. Die Gipsfaserplatten werden aus Altpapier herge¬ stellt und sind so im Sinne eines Recycling preiswert und insbesondere umweltfreundlich in der Produktionsphase. Derar¬ tige Faserplatten können zusätzlich mit elastischen Langfa¬ sermaterialien, z.B. Glasfasern, Steinwoll- oder Mineralwoll¬ fasern, Carbon- und Aramidfasern armiert werden. Gipεfaserplatten haben eine Dichte von etwaBasically, chipboard or fiberboard can be used, which contain components made of plaster or cement. Such boards are known, inter alia, as gypsum fiber boards, cement-bonded chipboard (Duripanel), gypsum-bonded chipboard and gypsum chipboard. Gypsum chipboard and gypsum fibreboard consist of cellulose with gypsum as a binder. The gypsum fibreboards are made from waste paper and are therefore inexpensive in terms of recycling and in particular environmentally friendly in the production phase. Such fiberboard can additionally be reinforced with elastic long fiber materials, for example glass fibers, rock wool or mineral wool fibers, carbon and aramid fibers. Gypsum fibreboards have a density of approximately
1,15 - 1,20 kg/1, eine Biegefestigkeit von .— 8,0 N/mm2 in Längsrichtung und ^ 8,5 N/mm2 in Querrichtung, eine Quer¬ zugfestigkeit von 0,3 - 0,4 N/mm2 und eine Brandschutzklasse A2. Der E-Modul derartiger Platten beträgt ca 3500 N/mm2 in Längsrichtung und ca 4000 N/mm2 in Querrichtung.1.15-1.20 kg / l, a bending strength of .8.0 N / mm 2 in the longitudinal direction and ^ 8.5 N / mm 2 in the transverse direction, a transverse tensile strength of 0.3-0.4 N / mm 2 and a fire protection class A2. The modulus of elasticity of such plates is approximately 3500 N / mm 2 in the longitudinal direction and approximately 4000 N / mm 2 in the transverse direction.
Es mußte zunächst angenommen werden, daß ein auf Zementbasis beruhendes Material für Gehäuse für Geräte der Unterhaltungs¬ elektronik nicht infrage kommt, da die besonderen Eigenarten und Vorteile des Werkstoffes Zement für derartige Geräte nicht relevant zu sein scheinen. Es hat sich jedoch gezeigt, daß durch das erfindungsgemäß verwendete Material eine über¬ raschend große Zahl von teilweise voneinander unabhängigen Vorteilen erzielt wird.It had to be assumed that a cement-based material for housings for consumer electronics devices was out of the question, since the special characteristics and advantages of the cement material do not seem to be relevant for such devices. However, it has been shown that the material used according to the invention achieves a surprisingly large number of advantages, some of which are independent of one another.
Das Material hat zunächst eine größere Umweltfreundlichkeit, und zwar in der Produktionsphase, in der Nutzungsphase und in der Entsorgungsphase. Bei der Produktion und der Verarbei¬ tung von bisher verwendeten Spanplatten fallen die schädli¬ chen Stoffe Formaldehyd und Harnsäure an. Bei dem erfindungε- gemäßen Material ist das nicht der Fall. Vielmehr werden dort in größerem Maße Gipε und Schwefel gebunden. Daε ist deshalb vorteilhaft, weil dieεe Stoffe in zunehmendem Maße bei der Rauchgasentschwefelung gewonnen werden, relativ we¬ nig Anwendungsmöglichkeiten haben und daher eine Verwendungs¬ möglichkeit dieser Stoffe hinsichtlicht Umweltfreundlichkeit vorteilhaft ist.The material is initially more environmentally friendly, namely in the production phase, in the use phase and in the disposal phase. The harmful substances formaldehyde and uric acid occur in the production and processing of chipboard used previously. This is not the case with the material according to the invention. Rather, gypsum and sulfur are bound there to a greater extent. This is advantageous because these substances are increasingly being obtained in flue gas desulfurization, have relatively few possible uses, and therefore a use of these substances is advantageous in terms of environmental friendliness.
Es wird außerdem eine Verbesserung der akustischen Perfor¬ mance der Geräte mit Gehäuse aus den erfindungsgmäßen Plat¬ ten erreicht. Das beruht darauf, daß die Gehäuse eine höhere Dämpfung und dadurch ein geringeres Klirrverhalten bei aku¬ stischer Anregung aufweisen. Erfindungsgemäße Gehäuse sind daher unempfindlicher gegen störende Resonanzeffekte. Es wird ferner eine geringere akustische Kopplung durch Kör- perεchall erreicht, so daß störende Mikrophonieerscheinungen bei bestimmten Geräten reduziert werden. In einem Fernsehemp¬ fänger kann beispielsweise der Lautsprecher über das Gehäuse Schwingungen auf die Bildröhre übertragen, die dort durch Anregungen der Lochmaske zu Bildstörungen führen können. Die¬ se Störungen werden ebenfalls verringert, so daß in bestimm¬ ten Fällen bisher angewandte Maßnahmen wie z.B. eine künstli¬ che Erhöhung der Masse des Magneten des Lautsprechers entfal¬ len können.There is also an improvement in the acoustic performance of the devices with housings made from the plates according to the invention. This is due to the fact that the housings have a higher damping and therefore a lower distortion behavior with acoustic excitation. Housings according to the invention are therefore less sensitive to disturbing resonance effects. There is also less acoustic coupling due to structure-borne noise, so that disturbing microphonic phenomena are reduced in certain devices. In a television receiver, for example, the loudspeaker can transmit vibrations to the picture tube via the housing, which can lead to picture disturbances there through excitations of the shadow mask. These disturbances are also reduced, so that in certain cases previously used measures such as an artificial increase in the mass of the magnet of the loudspeaker can be omitted.
Die reinen Materialkoεten werden durch die Erfindung eben¬ falls verringert. Es hat sich gezeigt, daß der Werkzeugver¬ schleiß bei dem Zuschneiden oder dem Fräsen der erfindungsge¬ mäßen Platten sogar geringer ist als bei der Bearbeitung von Spanplatten. Die Verarbeitung der erfindungsgemäßen Platten kann mit herkömmlichen Maschinen erfolgen.The invention also reduces the pure material costs. It has been shown that the tool wear when cutting or milling the boards according to the invention is even less than when machining chipboard. The plates according to the invention can be processed using conventional machines.
Das erfindungsgemäße Material hat eine geringere Brennbar¬ keit und somit eine erhöhte Betriebsεicherheit. Das verwende¬ te Material zählt zur Klasse A2, bezeichnet mit "schwer ent¬ flammbar". Dieser Vorteil kommt insbesondere dort zum Tra¬ gen, wo wie in den skandinavischen Ländern hohe Brandgefahr besteht und hohe Anforderungen hinsichtlich der Nicht- Brenn¬ barkeit gestellt werden.The material according to the invention has a lower flammability and thus an increased operational safety. The material used belongs to class A2, designated "flame-retardant". This advantage is particularly important where there is a high risk of fire, as in the Scandinavian countries, and high demands are made with regard to non-combustibility.
Das Material ist darüberhinauε tropenfest und besonders für klimatische Verhältnisse mit hohen Temperaturen und hoher Luftfeuchtigkeit geeignet.The material is also tropical-proof and particularly suitable for climatic conditions with high temperatures and high air humidity.
Die Erfindung wird anhand der Zeichnung am Beispiel eines Gehäuses für einen Fernsehempfänger erläutert. Darin zeigen Fig. 1 im Schnitt das Gehäuse eines Fernsehempfängers und Fig. 2, 3 eine Möglichkeit für die Herstellung von Kanten zwischen den erfindungsgemäßen Platten.The invention is explained with reference to the drawing using the example of a housing for a television receiver. 1 shows in section the housing of a television receiver and 2, 3 a possibility for the production of edges between the plates according to the invention.
Fig. 1 zeigt das Gehäuεe eineε Fernsehempfängers mit einer oberen Gehäuεewand 1, einer Seitenwand 2, dem Boden 3, der Bildröhre 4 und dem vorderen Deckrahmen 5. Der Deckrahmen 5 und die nicht dargestellte Rückwand sind in üblicher Weise als Kunststoffεpritzteil hergeεtellt. Die obere Gehäuεewand 1, die hintere Gehäusewand 2, die vordere nicht dargestellte Gehäusewand und der Boden 3 bestehen aus Gipsfaserplatten oder zementgebundenen Holzspanplatten mit einer Dicke von ca 10 mm. Eine zementgebundene Holzspanplatte ist z.B. unter dem Handelsnamen "Duripanel" handelsüblich. Die die einzel¬ nen Gehäusewände bildenden Platten sind dabei mit einer ein Furnier darstellenden Folie überzogen, die sich durchgehend ohne Unterbrechung über die Kanten des Gehäuses erstreckt. Die Eigenschaften gipsgebundener Spanplatten sind z.B. näher beschrieben in der WKI Mitteilung 404/1985, Sonderdruck aus tiz 1985, Nr. 10, Seite 756 bis 759.1 shows the housing of a television receiver with an upper housing wall 1, a side wall 2, the bottom 3, the picture tube 4 and the front cover frame 5. The cover frame 5 and the rear wall, not shown, are produced in the usual way as a molded plastic part. The upper housing wall 1, the rear housing wall 2, the front housing wall, not shown, and the base 3 consist of gypsum fiber boards or cement-bonded chipboard with a thickness of approximately 10 mm. A cement-bonded chipboard is e.g. commercially available under the trade name "Duripanel". The plates forming the individual housing walls are covered with a film representing a veneer, which extends continuously over the edges of the housing without interruption. The properties of gypsum-bonded chipboard are e.g. described in more detail in WKI Communication 404/1985, reprint from tiz 1985, No. 10, pages 756 to 759.
Die vier in Fig. 1 beschriebenen Gehäusewände bilden zu¬ nächst eine durchgehende starre Platte, die mit einer das Furnier bildenden Folie beschichtet ist. Diese Platte wird anschließend an den Stellen der vorgeεehenen Gehäuεekanten so gefräst, daß die Platte an diesen Stellen ohne Beschädi¬ gung der durchgehenden Folie insb'eεondere auf einen Winkel von 90° umknickbar ist.The four housing walls described in FIG. 1 first form a continuous rigid plate which is coated with a film forming the veneer. This plate is then milled at the locations of vorgeεehenen Gehäuεekanten so that the plate at these locations supply without Beschädi¬ the continuous film especially 'eεondere to an angle of 90 ° is umknickbar.
In den Fig. 2, 3 ist eine solche bekannte Lösung darge¬ stellt. Fig. 2. zeigt eine durchgehende Platte 6 in Form ei¬ ner Gipsfaserplatte oder ze en gebundenen Holzspanplatte, die der Gesamtheit der Flächen der vier Gehäuseteile gemäß Fig. 1 entspricht und an der Oberfläche mit einer ein Fur¬ nier bildenden Folie 7 versehen ist. An den später die Gehäu¬ sekanten bildenden Stellen wird die Platte durch eine Fräsma- schine geführt, wobei mehrere Einschnitte 8 eingefräεt wer¬ den, die bis auf die Folie 7 reichen, diese jedoch nicht be¬ schädigen. Zwischen den Einschnitten 8 bleiben somit aus dem Material der Platte 6 Stege 9 stehen, deren Höhe einen gerin¬ geren oder gleichen Wert aufweist als die Dicke der Platte 6. In die Einschnitte 8 wird anschließend eine Klebemasse 10 eingefüllt. Zu diesem Zweck wird die Platte 6 in eine Vorrichtung gebracht. Die Vorrichtung ist εo ausge¬ bildet, daß die Platte 6 unmittelbar nach dem Auftragen der Klebemaεεe 10 gebogen wird und εo lange in einer entsprechen¬ den Lage festgehalten wird, bis die Klebemasεe 10 erhärtet ist. Das Abbinden der Klebemaεεe 10 geεchieht innerhalb von wenigen Sekunden. Auf diese Weise ist die durch die Einschnitte 8 zunächst erheblich geschwächte Platte 6 wieder nahezu so fest wie die ungefraste Platte 6. Es sind auch Kle¬ beverfahren mit einer Kombination aus mehreren Klebern denk¬ bar, bei denen ein schnell bindender Kleber eine Vorfixie¬ rung und ein zweiter, langsam abbindender Kleber die Endfe¬ stigkeit ergibt. Derartige Verfahren mit zwei unterschied¬ lich wirkenden Klebern sind beschrieben in der DE-PS 29 21 182.Such a known solution is shown in FIGS. 2, 3. FIG. 2 shows a continuous plate 6 in the form of a gypsum fibreboard or a bonded chipboard which corresponds to the entirety of the surfaces of the four housing parts according to FIG. 1 and is provided on the surface with a film 7 forming a veneer. At the points later forming the housing edges, the plate is machine guided, wherein several incisions 8 are milled, which extend to the film 7, but do not damage it. Between the incisions 8 there are webs 9 made of the material of the plate 6, the height of which is less than or equal to the thickness of the plate 6. An adhesive 10 is then poured into the incisions 8. For this purpose, the plate 6 is placed in a device. The device is designed so that the plate 6 is bent immediately after the application of the adhesive mass 10 and is held in a corresponding position until the adhesive mass 10 has hardened. The setting of the adhesive mass 10 takes place within a few seconds. In this way, the plate 6, which is initially considerably weakened by the incisions 8, is again almost as strong as the unmilled plate 6. Adhesive processes with a combination of several adhesives are also conceivable, in which a fast-binding adhesive is a pre-fixing and a second, slowly setting adhesive gives the final strength. Such methods with two differently acting adhesives are described in DE-PS 29 21 182.
Durch die beεondere Anordnung der Einschnitte 8 bildet sich beim Biegen der Platte 6 automatisch eine εaubere runde Kan¬ te auε. Dieses durch die DE-OS 21 14 364 bekannte Verfahren zur Herstellung eines Gehäuseε aus einer Platte ist somit bei Gipsfaserplatten und zementgebundenen Holzspanplatten ebenfalls in vorteilhafter Weise anwendbar. Die zusätzlich dargestellte Folie 11 dient vorübergehend zur Stabilisierung der Folie 7 während des Herstellungsprozesses und wird da¬ nach wieder entfernt. Due to the special arrangement of the incisions 8, a clean round edge is automatically formed when the plate 6 is bent. This method, known from DE-OS 21 14 364, for producing a housing from a plate can thus also be used advantageously in the case of gypsum fiber boards and cement-bonded particle boards. The additionally shown film 11 serves temporarily to stabilize the film 7 during the manufacturing process and is then removed again.
