Abstract

Washing machines are often set up for use in flats. They cause vibration and noise, both of which often annoy the users as well as neighbours. The damper according to the invention provides a solution to this problem. To this end, the damper consists of two elastic plates which are provided on one side with protuberances. These protuberances are arranged in such a way that, when the plates are superposed, they engage loosely in one another like claws and make contact. Two plates with their protuberances form a unit. The damper can consist of several such units, which are held together by a likewise elastic ring. The ring and plates are connected to one another.

Description

Die Erfindung betrifft einen Vibrations- und Lärm­ dämpfer für Waschmaschinen etc.The invention relates to vibration and noise dampers for washing machines etc.

Waschmaschinen befinden sich heute in fast allen Wohnungen. Sie stehen gewöhnlich in der Küche oder im Badezimmer. Dieselben erzeugen im Betrieb beträchtliche Vibrationen und Lärm. Je nach Größe der Maschine und deren Tourenzahl sind diese erzeugten Vibrationen sowie Lärm nicht nur in der eigenen Wohnung vernehmbar, son­ dern auch in Nachbarwohnungen, was unangenehm ist und oft zu Streitigkeiten führt.Washing machines are found in almost all of them today Apartments. They are usually in the kitchen or in the Bathroom. The same produce considerable in operation Vibrations and noise. Depending on the size of the machine and their number of revs are these vibrations generated as well Noise not only audible in your own apartment, son but also in neighboring apartments, which is uncomfortable and often  leads to disputes.

Der erfindungsgemäße Vibrations- und Lärmdämpfer schafft hier Abhilfe. Diese wird dadurch erreicht, daß der Dämpfer aus einer Anzahl mit Dornen versehenen Platten besteht, die aus elastischem Material z. B. Gummi oder elastischem Kunststoff bestehen, wobei die Dorne mit denen die Platten versehen sind ineinandergreifen mit gegenseitiger Berührung, wodurch die Vibrationen und der Lärm neutralisiert werden. Diese Dämpfer werden an allen vier Ecken der Maschine untergeschoben. Je größer die Maschine ist und je höhere Tourenzahlen sie hat, um so mehr Platten mit Dornen können vorgesehen werden, um den gewünschten Zweck zu erreichen. Dabei sind je zwei Platten mit ihren Dornen gegeneinander gerichtet und lose ineinander verzahnt. Die Platten sind von einem Ring, der auch aus dem gleichen ela­ stischem Material besteht, umschlossen.The vibration and noise damper according to the invention creates remedy here. This is achieved in that the Damper from a number of plates with thorns consists of elastic material such. B. rubber or resilient plastic, the spikes with which the plates are interlocked with mutual contact, reducing the vibrations and the noise can be neutralized. These will be dampers pushed in at all four corners of the machine. Each the bigger the machine and the higher the number of revolutions has provided the more plates with thorns to achieve the desired purpose. Here are two plates with their thorns against each other directed and loosely interlocked. The plates are from a ring that is also from the same ela material consists, enclosed.

Im Gegensatz zu einfachen Unterlagen, neutralisieren diese Dämpfer die Vibrationen und den Lärm der Maschine.In contrast to simple documents, neutralize these dampers the vibrations and the noise of the machine.

Die Zeichnung veranschaulicht den Dämpfer in bei­ spielsweiser Ausführung. Es zeigtThe drawing illustrates the damper in at game-like execution. It shows

Fig. 2 einen Querschnitt der Platte als Oberteil, Fig. 2 shows a cross section of the plate as an upper part,

Fig. 3 einen Querschnitt der unteren Platte mit Dornen, die zwischen die Dorne der oberen Platte passen, Fig. 3 shows a cross-section of the lower plate, spikes, the fit between the pins of the upper plate,

Fig. 4 die Seitenansicht eines kompletten Dämpfers, teilweise im Schnitt. Fig. 4 is a side view of a complete damper, partly in section.

Der Dämpfer besteht aus einer oberen Platte 1 mit nach unten gerichteten Dornen 2 und einer unteren Platte 3 mit nach oben gerichteten Dornen 4. Die Dorne 2 und 4 greifen lose ineinander und haben gegenseitige Berührung. Dies stellt eine Einheit dar. Mehrere sol­ cher Einheiten sind übereinander geschichtet und durch einen Ring 5 zusammengehalten. Sowohl die Platten 1, 3 nebst Dornen 2, 4, wie auch der Ring 5 bestehen aus elastischem Material z. B. Gummi oder elastischem Kunst­ stoff.The damper consists of an upper plate 1 with thorns 2 pointing downwards and a lower plate 3 with thorns 4 pointing upwards. The mandrels 2 and 4 interlock loosely and have mutual contact. This represents a unit. Several such units are stacked one above the other and held together by a ring 5 . Both the plates 1, 3 and thorns 2, 4 , as well as the ring 5 are made of elastic material such. B. rubber or elastic plastic.

Der Dämpfer kann in verschiedenen Größen hergestellt werden und aus mehreren Einheiten bestehen. Durch das krallenartige, lose Ineinandergreifen der Dorne 2, 4, die gegenseitige Berührung haben, werden Vibration und Lärm der Maschine wirksam bekämpft bzw. neutralisiert. Die Anbringung der Dämpfer an der Maschine ist ganz einfach. An jeder Ecke der Maschine wird ein Dämpfer untergeschoben.The damper can be made in different sizes and consist of several units. The claw-like, loose interlocking of the mandrels 2, 4 , which have mutual contact, effectively combats or neutralizes the vibration and noise of the machine. Attaching the dampers to the machine is very easy. At each corner of the machine, a damper is pushed in.
