The object of the invention forms a foot pad for typewriters, calculating machines, etc. that is suitable to dampen the noises that arise when working with these machines as much as possible.

Im wesentlichen besteht die Fußunterlage aus . einer in einer Filzplatte eingebetteten Blechhülse, welche an ihrem oberen Rand in einer Umbördelung eine nach abwärts trichterförmig verlaufende Einlage mit einwärts gekehrten federnden Zähnen festklemmt.Essentially, the foot pad consists of. one in a felt pad embedded sheet metal sleeve, which at its upper edge in a bead a downwardly funnel-shaped insert with inwardly turned resilient Teeth stuck.

In der Zeichnung ist in Fig. = im senkrechten Schnitt, in Fig. z in der Draufsicht eine Ausführungsform einer schalldämpfenden Fußunterlage gemäß der Erfindung dargestellt.In the drawing, in Fig. = In vertical section, in Fig. Z in the top view of an embodiment of a sound-absorbing foot pad according to FIG Invention shown.

In der Filzplatte a ist die vorteilhaft nach oben verjüngte Blechhülse b eingebettet bzw. eingepreßt, die an ihrem oberen Rande eine nach innen gekehrte Umbördelung b1 trägt. In dieser Umbördelung wird eine nach unten trichterförmig verlaufende Einlage c durch Klemmung festgehalten, welche eine Anzahl federnde nach abwärts gekehrte und nach innen herausgebogene längere und kürzere Zähne d, dl trägt.In the felt plate a is the sheet metal sleeve which is advantageously tapered upwards b embedded or pressed in, the one facing inwards at its upper edge Bead b1 carries. In this bead one becomes funnel-shaped downwards extending insert c held by clamping, which a number of resilient after longer and shorter teeth d, dl, which are turned downwards and curved inwards.

In diese Einlage mit den federnden Zähnen wird der Fuß der Schreibmaschine o. dgl. eingesetzt. Da der Fuß der Maschine nunmehr auf den federnden Zähnen d, dl der Einlage c aufruht und von . denselben festgehalten wird; werden die Erschütterungen der Maschine von der federnden Auflage zum Teil paralysiert, zum Teil von der Hülse b an die Filzplatte a weitergeleitet und von derselben aufgefangen.The foot of the typewriter is placed in this insert with the resilient teeth or the like. Used. Since the foot of the machine is now on the resilient teeth d, dl of the insert c rests and of. the same is held; become the tremors the machine is partially paralyzed by the resilient support and partially by the sleeve b forwarded to the felt plate a and caught by the same.
