Description

  

  Schall- und     vibrationsdämpfende    Unterlage für Tisch- und Maschinenfüsse    Zur Verhinderung der Übertragung von  Vibrationen und Betriebsgeräuschen von Ma  schinen auf den Fussboden verwendete man  bisher unter die Tisch- oder Maschinenfüsse       Legbare    Gummi- oder Filzunterlagen. Bei Ma  schinen, welche starke Vibrationen     erzeugen,     wie zum Beispiel Nähmaschinen, Knopfloch  maschinen, Rechenmaschinen,     Buehhaltungs-          masehinen,    Schreibmaschinen usw., ist die Ver  wendung solcher Unterlagen nicht befriedi  gend.  



  Gegenstand, der Erfindung ist eine     schall-          und        vibrationsdämpfendeUnterlage    für     Tisch-          und    Maschinenfüsse, welche erfindungsgemäss  aus einer vertikal wirkenden Dreckfeder und  zwei den Enden der Druckfeder anliegenden,  gummielastischen     Auflagetellern    besteht..  



  Die dem Fussboden bzw. Tisch- oder Ma  schinenfuss anliegenden Aussenseiten der Auf  lageteller sind zweckmässig konkav ausgebil  det, während die der Druckfeder anliegen  den Innenseiten eine Vertiefung für den Ein  griff der Enden der Druckfeder aufweisen  können.  



  Die erfindungsgemässe Unterlage zeichnet  sieh durch eine überraschende     vibrations-          und    geräuschdämmende Wirkung aus, welche  den Betrieb von     starke    Vibrationen und Be  triebsgeräusche verursachenden Maschinen,  wie Nähmaschinen, Knopflochmaschinen usw.,  auch in Wohn- und Miethäusern ohne     StÖ-          rung    der übrigen Hausbewohner ermög  lichen.

      In der Zeichnung ist beispielsweise eine  Ausführungsform des Erfindungsgegenstan  des dargestellt, und zwar zeigt:       F'ig.1    einen senkrechten Schnitt durch  die Unterlage und       Fig.    '2 einen horizontalen Schnitt gemäss  Linie     II-II    in     Fig.1.     



  Die dargestellte Unterlage weist eine verti  kale, als Schraubenfeder gebildete Druck  feder 1 auf, welche mit horizontalen Auf  lageflächen versehen ist. Dem Ober- und Un  terende der Schraubenfeder 1 liegt je ein Auf  lageteller 2 bzw. 3 aus Gummi an. Die Auf  lageteller weisen an ihrer der Druckfeder 1  zugekehrten Innenseite eine Vertiefung 4 für  den Eingriff der Enden- der Druckfeder     auf.     Die äussern Auflageflächen 5 sind     konkav     ausgebildet und     ermöglichen    eine     gute    Auf  lage auf dem Fussboden bzw. eine     gute    Auf  lage des Tisch- oder Maschinenfusses F. Der  obere Auflageteller 2 ist mit einer runden  Öffnung     ss    versehen.

   In diese Öffnung kann  gegebenenfalls die Laufrolle eines     Nähmaschi-          nenfusses    eingreifen,  Das Gewicht der Maschine oder des Ma  schinentisches wird von der Druckfeder auf  genommen, welche ebenfalls die Vibrationen  kompensiert. Die Betriebsgeräusche werden  durch die Gummiteller     und    die diese verbin  dende Druckfeder     weitmögliehst    gedämmt, so  dass     keine    nennenswerte 'Geräuschübertragung  auf den Fussboden stattfinden kann.



  Sound and vibration-absorbing pad for table and machine feet To prevent the transmission of vibrations and operating noises from machines to the floor, rubber or felt pads that could be placed under the table or machine feet were previously used. In the case of machines that generate strong vibrations, such as sewing machines, buttonhole machines, calculating machines, buehhaltungs- masehinen, typewriters, etc., the use of such documents is not satisfactory.



  The subject matter of the invention is a sound and vibration dampening pad for table and machine feet, which according to the invention consists of a vertically acting tension spring and two rubber-elastic support plates resting against the ends of the compression spring ..



  The outer sides of the on-position plate resting on the floor or table or machine base are expediently concave, while those of the compression spring resting on the inner sides can have a recess for the ends of the compression spring to handle.



  The pad according to the invention is characterized by a surprising vibration and noise dampening effect, which enables the operation of strong vibrations and operating noises such as sewing machines, buttonhole machines, etc., even in residential and rental houses without disturbing the other residents.

      In the drawing, for example, an embodiment of the subject matter of the invention is shown, namely: FIG. 1 shows a vertical section through the support and FIG. 2 shows a horizontal section along line II-II in FIG.



  The pad shown has a verti cal, formed as a helical spring compression spring 1, which is provided with horizontal support surfaces. The upper and lower end of the coil spring 1 is each on a position plate 2 and 3 made of rubber. The on position plates have on their inner side facing the compression spring 1 a recess 4 for the engagement of the ends of the compression spring. The outer support surfaces 5 are concave and allow a good position on the floor or a good position of the table or machine base F. The upper support plate 2 is provided with a round opening ss.

   The roller of a sewing machine foot can intervene in this opening if necessary. The weight of the machine or the machine table is taken up by the compression spring, which also compensates for the vibrations. The operating noises are insulated as much as possible by the rubber plate and the compression spring connecting it, so that no significant noise can be transmitted to the floor.
