Description

Neben der Verwendung guter Resonanzhölzer, wie sie für Sprechmaschinen, Musikinstrumente, Radioapparate o. dgl. verwendet werden, ist oft ein Plattenmaterial erwünscht, mit dessen Hilfe insbesondere Gehäuse (Truhen oder Schränke) für Sprechmaschinen u. dgl. so hergestellt werden können, daß ihre Wandungen wenig oder gar nicht mitklingen.In addition to the use of good resonance woods, such as those used for speaking machines, musical instruments, Radio sets or the like are used, a plate material is often desired, with the help of which housing in particular (Chests or cupboards) for speaking machines and the like can be produced in such a way that their walls resonate little or not at all.

Es ist bekannt, die- Wände der Schallwege von Sprechmaschinen und Radioapparaten aus Blei herzustellen, um die tondämpfende Eigenschaft dieses Metalls zur Unterdrükkung von Resonanzschwingungen und Nebengeräuschen auszunutzen. Um die hiermit verbundenen baulichen Schwierigkeiten zu vermeiden, hat man auch die inneren Flächen von Sprechmaschinengehäusen o. dgl. vielfach nur mit Bleiplatten bekleidet.It is known that the walls of the sound paths from talking machines and radio sets made of lead to the sound attenuating ones Property of this metal for suppressing resonance vibrations and background noises to take advantage of. In order to avoid the structural difficulties associated with this, one also has the inner surfaces of speaking machine housings o. the like. Often clad only with lead plates.

ao Den Gegenstand der Erfindung bildet nun ein aus Sperrholz bestehendes Plattenmaterial, das nicht einfach mit Bleiblech armiert wird, sondern bei welchem dieses in Form einer oder mehrerer festeingefügten Zwischenlagenao The object of the invention now forms a sheet material made of plywood, which is not simply reinforced with lead sheet, but in which this is in the form of a or several firmly inserted intermediate layers

»5 verwendet wird, das derart in inniger Verbindung mit den Holzauflagen (Furnieren) steht, daß. sie zusammen ein eng gekoppeltes Schwingungssystem bilden, bei welchem die Schichten sich gegenseitig an der Ausbildung akustischer Schwingungen hindern. Es wird auf diese Weise ein Halbfabrikat geschaffen, das von der verarbeitenden Industrie in gewohnter Weise nur zugeschnitten und zusammengestellt zu werden braucht. Abgesehen davon, daß das Blei bei dieser Verwendungsart vollkommen verkleidet ist und die Platten ihr natürliches Aussehen behalten, wird durch die in die Platten eingefügte Bleizwischenlage eine starke Dämpfung der Schwingungsfähigkeit der auf beiden Seiten der Bleizwischenlage aufgebrachten Holzfurniere erreicht. Diese Dämpfung wird um so wirksamer, je unharmonischer das Verhältnis der aufgeleimten Auflagen zueinander ist.»5 is used, which is so intimately connected with the wooden supports (veneers) it says that. together they form a closely coupled oscillation system in which the Layers prevent each other from developing acoustic vibrations. It will In this way a semi-finished product is created that is used by the manufacturing industry Way just needs to be tailored and put together. Apart from the fact that the lead in this type of use is completely clad and the panels retain their natural appearance is achieved by the fact that they are inserted into the panels Lead liner a strong dampening of the oscillation ability of the on both Sides of the lead interlayer reached wood veneer. This attenuation will the more effective, the more inharmonious the relationship between the glued-on editions is.

Die Bleizwischenlage wird vorteilhaft in gerauhtem Zustand sowie mit sieb- oder gitterartigen Durchlochungen verwendet, um einerseits eine feste Bindung unter Verwendung eines Blei leicht anätzenden Bindemittels mit den Auflagen zu erzielen, andererseits der Bleizwischenlage die notwendige Ausdehnung zu erlauben und zu verhindern, daß das Material unnötig schwer wird. Die Löcher des Bleigitters können mit Leim und geeigneten Füllstoffen (Sägemehl ο. dgl.) ausgefüllt werden. Auch können abwechselnd mehrere Schichten Holz und Blei aufeinander geleimt werden.The lead liner is beneficial in roughened condition as well as with sieve- or grid-like perforations used to on the one hand, a firm bond using a binding agent that is slightly corrosive to lead to achieve with the requirements, on the other hand to allow and prevent the lead interlayer from the necessary expansion, that the material becomes unnecessarily heavy. The holes in the lead grid can be filled with glue and suitable fillers (sawdust, etc.). Also can take turns several layers of wood and lead are glued together.

Das neue' Plattenmaterial kann für alle möglichen akustischen Zwecke dienen. Außer für den Bau von Sprechmaschinen, Lautsprechern, Radioapparaten, Schreibmaschinentischen usw. eignet es sich auch vorzüglich für Wandtäfelungen, Schallkulissen o. dgl.The new 'plate material can be used for all kinds of acoustic purposes. Except for the construction of speaking machines, loudspeakers, radios, typewriter tables etc. it is also ideal for wall paneling, soundscapes or the like.

In der Zeichnung sind zwei Ausführungsbeispiiele der Platten gemäß der Erfindung, und zwar im Querschnitt veranschaulicht.In the drawing are two exemplary embodiments of the panels according to the invention, namely illustrated in cross section.

Abb. ι zeigt einen Schnitt durch eine Platte, die aus einer ungelochten Bleizwischenlage α und zwei verschieden starken Sperrholzauflagen b und c besteht.Fig. Ι shows a section through a plate, which consists of an unperforated lead intermediate layer α and two different thicknesses of plywood layers b and c .

In Abb. 2 ist der Querschnitt einer Platte mit mehreren abwechselnd aufeinanderfolto genden Schichten aus Holz und Blei dargestellt. Die Bleizwischenlagen d und e sind gitterartig gelocht und mit Füllstoffen ausgefüllt evtl. auch mit Zwischenlagen / aus dünnem Papier versehen.In Fig. 2 the cross-section of a plate with several alternating layers of wood and lead is shown. The lead intermediate layers d and e are perforated like a grid and filled with fillers and possibly also provided with intermediate layers / made of thin paper.
