Abstract

The record player turntable mat (1) has a relief pattern formed on both its sides, so that the mat (1) can be used either side up. The relief pattern on the two sides of the mat (1) has a different appearance. Pref. the turntable mat (1) is made of natural or synthetic rubber and the relief pattern on one side comprises a series of concentric annular ridges (2, 3, 4) while that on the other side comprises a number of spaced radial ridges (6, 7) which may be of varying lenghts. The mat (1) has a circular hole (5) at the centre for fitting over the record player spindle.

Description

Belagscheibe für einen Plattenteller Cover disc for a turntable

Plattenspielerteller sind überlicherweise mit einer Belagscheibe aus Gummi oder ähnlichem Material versehen, die eine gleichmäßige und schonende Auflage der Schallplatte gewahrleisten soll. Durch die dämpfende Wirkung der Belagscheibe sollen Eigenschwingungen der Schallplatte vermieden werden.Turntables are usually made with a rubber disc Rubber or similar material provided that an even and gentle support the record should guarantee. Due to the dampening effect of the lining disc natural vibrations of the record should be avoided.

Die Auflage wird durch reliefartig vorstehende, beispielsweise radial oder ringförmig angeordnete Rippen an der Oberfläche der Belagscheibe verbessert. Da der Plattenteller ein großes sichtbares Bauteil des Plattenspielers ist, wird der Gesamteindruck des Plattenspielers von der Gestaltung der die Oberfläche des Plattentellers bildenden Oberseite der Belagscheibe wesentlich gepragt. Aus diesem Grunde wird meist für jeden Plattenspieler-Typ, insbesondere für Plattenspieler verschiedener Güteklassen, eine anders aussehende Belagscheibe verwendet. Zur Erfüllung dieser Forderung ist für jeden Belagscheiben-Typ ein eigenes Formwerkzeug zur Herstellung der Belagscheiben erforderlich.The support is by means of relief-like protruding, for example radially or annularly arranged ribs on the surface of the facing disc improved. Since the turntable is a large visible component of the turntable, will the overall impression of the turntable from the design of the surface of the The turntable forming the upper side of the facing disc is substantially embossed. For this The reason is mostly for every type of turntable, especially for turntables different grades, a different-looking lining was used. To fulfillment This requirement is a separate molding tool for production for each type of facing disc of the lining washers required.

Der Erfindung liegt die Aufgabe zugrunde, die Herstellung der Belagscheiben für die Plattenteller von Plattenspieler zu vereinfachen.The invention is based on the object of producing the facing disks for the turntable of turntable to simplify.

Diese Aufgabe wird durch dic im Patentanspruch angegebene Erfindung gelöst.This object is achieved by the invention specified in the claim solved.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die mit 1 bezeichnete Belagscheibe ist aus Gummi in einem Stück hergestellt. An der einen Seite ist die Belagscheibe mit ringföraigen Rippen 2, 3 und 4 versehen. Im Mittelpunkt der Belagscheibe befindet sich eine Öffnung 5, mit der die Belagscheibe auf die Achse des Plattentellers gesteckt wird. Auf der anderen Seite ist die Belagscheibe 1 mit radial angeordneten Rippen 6 und 7 versehen. Das dargestellte Beispiel zeigt, wie unterschiedlich die Oberfläche der Belagscheibe, die mit der Platte in Berührung kommt, gestaltet werden kann. Die Oberflächen der erfindungsgemäßen Belagscheibe können auch durch andere reliefartige Erhöhungen oder auch Vertiefungen verschieden gestaltet werden.An exemplary embodiment of the invention is shown in the drawing. The lining disc designated by 1 is made of rubber in one piece. At On the one hand, the lining disc is provided with annular ribs 2, 3 and 4. In the center of the facing disc there is an opening 5 with which the facing disc is placed on the axis of the turntable. On the other side is the lining disc 1 provided with radially arranged ribs 6 and 7. The example shown shows how different the surface of the facing disc that is in contact with the plate comes, can be designed. The surfaces of the facing disc according to the invention can also be different by other relief-like elevations or depressions be designed.

Die erfindungagemaße Belagscheibe kann für zwei verschiedene Plattenspieler mit völlig unterschiedlichem Aussehen verwendet werden, indem im einen Fall die eine Seite der Belagscheibe und im anderen Fall die andere Seite als die die Platte berührende Oberseite verwendet wird. Dadurch wird die Zahl der erforderlichen Formteile zur Herstellung der Belagscheiben, wenn mehrere verschiedene Belagscheiben benötigt werden, auf die Hälfte reduziert. Da dementsprechend die Belagscheibe mit einer höheren Stückzahl hergestellt werden kann, wird die Herstellung verbilligt.The disc according to the invention can be used for two different turntables can be used with completely different looks, in one case the one side of the facing disc and in the other case the other side than the plate touching top is used. This will reduce the number of moldings required for the production of the facing disks, if several different facing disks are required are reduced by half. Since accordingly the lining disc with a If higher quantities can be produced, production is cheaper.
