Description

Plattenteller für Sprech- und ähnliche Maschinen. Die Erfindung bezieht sich auf Plattenteller für Sprech- und ähnliche Maschinen, welche mit einer am Rande angeordneten Ringnut zur Aufnahme und Befestigung des Randes der zur Schonung der PLIten dienenden Auflage aus weichem Stoff, wie Filz, Tuch, Plüsch o. dgl., versehen sind. Während bei den bekannten Ausführungen dieser Art die Ringnut am Rande in senkrechter oder schräger Richtung zur Oberfläche des Plattentellers angebracht ist, besteht die Neuerung gemäß der Erfindung darin, daß die Ringnut in der Ulmfläche des Plattentellers, und zwar parallel zur Plattentelleroberfläche angeordnet ist. Durch diese Befestigungsart wird der obere Rand des Plattenteliers durch die tim ihn herumgelegte Stofflage völlig verdeckt, so daß ein Verschrammen der Platten, insbesondere bei ungeschicktem schiefen Aufsetzen derselben, sicher vermieden wird. Außerdem kann die Nut in der Umfläche parallel zur Telleroberfläche, d. h. senkrecht zur Plattentellerachse, leicht und sicher eingestoßen oder auf sonstige Weise eingearbeitet werden, da seitliche Schwankungen des eingespannten Tellers, wie sie bei derartigen, im Verhältnis zu ihrem großen Umfang dünnen und daher zur Federung neigendeü Scheiben beim Einstoßen oder Eindrehen von am Rande des Tellers senkrecht oder schräg zur Telleroberfläche verlaufenden Ringnuten auftreten können, vermieden werden.Turntables for speech and similar machines. The invention relates to turntables for speech and similar machines, which are provided with an annular groove arranged on the edge for receiving and fastening the edge of the soft material such as felt, cloth, plush o . While in the known designs of this type the annular groove is attached to the edge in a perpendicular or oblique direction to the surface of the turntable, the innovation according to the invention is that the annular groove is arranged in the Ulm surface of the turntable, parallel to the turntable surface. With this type of fastening, the upper edge of the plate tent is completely covered by the layer of fabric placed around it, so that scratching of the plates, especially if they are placed in an awkward, inclined position, is reliably avoided. In addition, the groove in the peripheral surface can be parallel to the plate surface, i. H. perpendicular to the turntable axis, easily and securely pushed in or incorporated in some other way, since lateral fluctuations of the clamped plate, as they are with such, thin in relation to their large circumference and therefore tend to resilience ü discs when pushing in or screwing in from the edge of the plate perpendicular or annular grooves running obliquely to the plate surface can be avoided.

Der Erfindungsgegenstand ist auf der Zeichnung beispielsweise veranschaulicht, und zwar als Querschnitt durch die Achse des Plattentellers.The subject matter of the invention is illustrated in the drawing, for example, as a cross section through the axis of the turntable.

Auf der Zeichnung bezeichnet i den Plattenteller und .2 die Auflage aus Stoff. Gemäß der Erfindung ist die zur Aufnahme und Befestigung der Stoffauflage 2 dienende Ringnut 3 in der Umfläche des Plattentellers i, und zwar parallel zur Plattenoberfläche angebracht. Das Befestigen des Stoffrandes in der Ringnut kann beispielsweise durch ein in die Ringnut gebrachtes Klebmittel bewirkt werden.In the drawing, i denotes the platter and .2 the fabric overlay. According to the invention, the annular groove 3, which is used to receive and fasten the material layer 2, is provided in the peripheral surface of the turntable i, specifically parallel to the disk surface. The fastening of the material edge in the annular groove can be effected, for example, by an adhesive placed in the annular groove.
