Description
Um die starke.-Resonanz von Sdhreibmaschinentischen, insbesondere solchen mit Versenkeinrichtung, abzudämmen, werden meist besondere Filz--oder Gummiunterlagen verwendet, so daß die Schreibmaschine mit ihren festen Gummifüßen nicht unmittelbar auf der Schreibtischplatte ruht. Die Übertragung der Last erfolgt jedoch stets mit unmittelbarer Zwischenschaltung der -elastischen, Unterlage. Diese Dämpfung ist aber nicht ausreichend, um das bei der Benutzungder Maschine entstehende Geräusch genügend. wirksam zu verhindern. Das gilt auchdann, wenn die dämpfenden Unterlagplatten noch in Verbindung« mit Blechrahmen zur Anwendung kommen, weil dabei die Schwingungen noch zu stark auf die Schreibtischplatte übertragen werden.To the strong. -Response from Sdhreib machine tables, in particular those with a lowering device to be dammed are usually special felt or rubber pads used so that the typewriter with its solid rubber feet is not immediately resting on the desk top. However, the load is always transferred with Immediate interposition of the -elastic, underlay. This attenuation is but not sufficient to prevent the noise generated when using the machine enough. effectively prevent. This also applies when the cushioning support plates can still be used in conjunction with sheet metal frames because the vibrations can still be transferred too strongly to the desktop.
Die Erfindung besteht demgegenüber darin, daß die Tragplatte der Maschine in einen Ausschnitt der Tischplatte zwischen in dieser eingeklemmten Gummileisten schwebend eingesetzt ist. Dadurch ruht die Maschine weder mit ihren eigenen Gummifüßen noch mit einer elastischen Unterlage unmittelbar auf der Tischplatte auf, sondern unter Vermittlung einer hebelart#igen Wirkung. Die Geräuschdämpfung ist deshalb viel wirksamer.The invention consists in the fact that the support plate of the machine in a section of the table top between rubber strips clamped in this is inserted floating. As a result, the machine does not rest with its own rubber feet still with an elastic pad directly on the table top, but with the mediation of a lever-like effect. The noise attenuation is therefore much more effective.
Die Zeichnung stellt die Erfindung beispielsweise dar, und, zwar ist Abb. i die Oberansicht auf die in die Tischplatte eingesetzte Tragplatte, bb. 2 ein Querschnitt nach. Linie .2-2 der Abb. i, Abb. 3 ein ähnlicher Querschnitt eines abweichenden Beispiels unter Fortlassung der in Abb. 2 angedeuteten Schreibmaschine; Abb. 4 zeigt ein weiteres Beispiel im Querschnitt. Die Schreibmaschine c ruht mit ihren Gummifüßen c' nicht unmittelbar auf einer elastischen Unterlage, sondern auf einer Tragplatte f, die unter Zwischenschaltung von Gummileisten e in die Tischplatte a eingeklemmt ist. Dadurch tritt zu der dämpfenden Federwirkung des Gummis noch die hebelartige Wirkung, die von der Last der Schreibmaschine unter Vermittlung der Tragplatte f über die Gummileisten e ausgeübt wird.The drawing shows the invention as an example, namely Fig. I is the top view of the support plate inserted into the table top, bb. 2 a cross-section according to. Line .2-2 of Fig. I, Fig. 3 shows a similar cross-section of a different example, omitting the typewriter indicated in Fig. 2; Fig. 4 shows another example in cross section. The typewriter c rests with its rubber feet c 'not directly on an elastic base, but on a support plate f which is clamped into the table top a with the interposition of rubber strips e. As a result, in addition to the damping spring effect of the rubber, there is also the lever-like effect, which is exerted by the load of the typewriter under the mediation of the support plate f via the rubber strips e.
Die Gummileisten e umgreifen sowohl die Kanten der Tischplatte a wie auch der Tragplatte f von oben und unten. flanschartig, können jedoch auch im Querschnitt eine abweichende Gestaltung erhalten, wie z. B. nach Abb. 3 oder 4. Im letzteren Beispiel verlaufen die Anlagekan#ten der Trag' platte f und der Schreibtischplatte a keilförmigg.The rubber strips e encompass both the edges of the table top a and the support plate f from above and below. flange-like, but can also have a different design in cross-section, such as. B. according to Fig. 3 or 4. In the latter example, the abutment edges of the support plate f and the desk top a are wedge-shaped.
Die Leisten e können einen Rahmen g nach Abb. 5 bilden, also die l'ragplatte f von allen vier Seiten umschließen.The strips e can form a frame g according to Fig. 5 , that is, enclose the support plate f on all four sides.
