Abstract

The device comprises a base plate (31) which is made from a sound-resistant centre part (3) connectable to the mechanical system and designed to connect two wing members (32a, 32b ) together. The wing members are each connected to a side part (22a, 22b) of a sound-resistant angular element (2a, 2b) through a sound-soft elastic layer (4a, 4b). The angular element has a base part (21a, 21b) connectable with the assembly body. The nature and dimensions of the two sound-soft layers is selected taking into consideration the incline of the wing members and side parts so that the assembled sound protection device expands the mechanism system into a vibration system whose resonance frequency is below the frequency range of disturbing sounds.

Will in one Conference hall e.g. a lecture, so they can by moving doors or partitions in neighboring rooms caused noise in the conference room are perceived as disturbing. Bother as well such noises in private homes in particular during the night time when the noise level is otherwise has dropped to a minimum value. Modern locking systems may be provided with drives that are driven by electric motors. From the electric motors Vibrations caused can therefore also to appear disruptive.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Schallschutzvorrichtung für Systeme zu schaffen, die wenigstens ein bewegliches, insbesondere ein verschiebbares Teil aufweisen.The present invention is therefore based on the object to create a soundproofing device for systems, the at least one movable, in particular a movable Have part.

Die Lösung dieser Aufgabe gelingt mit den in Anspruch 1 angegebenen Massnahmen. Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben.This problem is solved with the in claim 1 specified measures. Advantageous embodiments of the Invention are specified in further claims.

Die für ein mechanisches System mit wenigstens einem beweglichen Teil vorgesehene Schallschutzvorrichtung verhindert die Übertragung von störenden Schallwellen von diesem System auf ein benachbartes System. Derartige mechanische Systeme bestehen z.B. aus einer Schiene, in der ein mit einer Schiebetür oder einer Trennwand verbundenes Laufwerk verschiebbar gelagert ist. Die Schiene wird mittels der Schallschutzvorrichtung z.B. an der Decke eines Raumes oder an einem Schrankoberboden befestigt.The one for a mechanical system with at least one Moving part provided noise protection device prevented the transmission of disturbing sound waves from this system to a neighboring system. Such mechanical systems exist e.g. from a rail, in the one connected with a sliding door or a partition Drive is slidably mounted. The rail will by means of the soundproofing device e.g. on the ceiling a room or attached to a cupboard top.

Die Schallschutzvorrichtung, die zusammen mit dem mechanischen System ein Schwingungssystem bildet, ist derart ausgestaltet, dass die Resonanzfrequenz des Schwingungssystems ausserhalb des Frequenzbereichs liegt, innerhalb dem ein ungedämpftes System störende Schallwellen erzeugt. Schallwellen ausserhalb des Resonanzbereichs werden in der Schallschutzvorrichtung an zwei seriell geschalteten Reflexionsstellen reflektiert.The soundproofing device, which together with the mechanical System forms a vibration system, is designed such that the resonant frequency of the vibration system is outside the frequency range, within which an undamped system generates disturbing sound waves. Sound waves outside the resonance range are in the Soundproofing device on two series connected Reflected points reflected.

Die Schallschutzvorrichtung besteht vorzugsweise aus zwei an einem Montagekörper zu befestigenden Winkelelementen, die je über eine schallweiche, elastische Schicht mit einem Mittelstück verbunden sind, an dem das mechanische System aufgehängt wird. Die Winkelelemente und das Mittelstück sind vorzugsweise derart ausgestaltet, dass durch diese ein Druck auf die schallweiche Schicht ausgeübt wird, so dass langfristig verhindert wird, dass sich die mit einem Klebstoff befestigte schallweiche Schicht vom Mittelstück sowie dem zugehörigen Winkelelement ablösen kann. In einer bevorzugten Ausgestaltung wird zudem verhindert, dass sich das Mittelstück vollständig von den Winkelelementen lösen kann, wenn die schallweiche Schicht bei einem Brandfall geschmolzen wird.The soundproofing device preferably consists of two angle elements to be attached to a mounting body, each with a soft, elastic layer are connected to a center piece on which the mechanical System is hung.

Fig. 1 zeigt eine erfindungsgemässe Schallschutzvorrichtung 1, die zur Befestigung eines mit einem beweglichen, insbesondere einem verschiebbaren Teil versehenen mechanischen Systems dient. Das mechanische System besteht z.B., wie in Fig. 4 gezeigt, aus einer Schiene 5, die über die Schallschutzvorrichtung an einem Montagekörper befestigt wird und einem in der Schiene 5 geführten Laufwerk 6, durch das eine Schiebetür oder ein Trennelement verschiebbar gehalten ist.1 shows a soundproofing device according to the invention 1, which is used to attach one with a movable, in particular a mechanical part provided with a movable part Systems serves. The mechanical system exists for example, as shown in Fig. 4, from a rail 5 which over the soundproofing device on a mounting body is attached and a guided in the rail 5 Drive 6 through which a sliding door or a Separating element is held displaceably.

Die Schallschutzvorrichtung 1, durch die durch das bewegliche Teil verursachte Schwingungen stark gedämpft und zum Teil reflektiert werden, besteht aus einem schallharten, vorzugsweise aus Metall bestehenden Mittelstück 3 und zwei schallharten, vorzugsweise aus Metall bestehenden Winkelelementen 2a, 2b.The soundproofing device 1 through which by the movable Partly caused vibrations strongly damped and Part reflected, consists of a reverberant, preferably made of metal middle piece 3 and two reverberant, preferably made of metal angle elements 2a, 2b.

Das Mittelstück 3 weist eine mit dem mechanischen System, z.B. mit der Schiene 5, verbindbare Basisplatte 31 auf, die zwei Flügelstücke 32a, 32b miteinander verbindet, welche je über eine schallweiche, elastische Schicht 4a bzw. 4b mit einem Seitenteil 22a bzw. 22b eines Winkelelementes 2a bzw. 2b verbunden sind. Die Winkelelemente 2a, 2b weisen nebst dem Seitenteil 22a bzw. 22b ein Basisteil 21a, 21b auf, das mit dem Montagekörper verbindbar ist.The center piece 3 has one with the mechanical system, e.g. with the rail 5, connectable base plate 31, which connects the two wing pieces 32a, 32b, which each with a soundproof, elastic layer 4a or 4b with a side part 22a or 22b of an angle element 2a and 2b are connected. The angle elements 2a, 2b have a base part in addition to the side part 22a or 22b 21a, 21b, which can be connected to the mounting body.

Die montierte Schallschutzvorrichtung erweitert ein daran angeschlossenes mechanisches System zu einem Schwingungssystem mit wenigstens einer Resonanzfrequenz, die unterhalb des Bereichs der Frequenzen störender Schallanteile liegt, die beim Verschieben des beweglichen Teils entstehen können. Abgestimmt wird das Schwingungssystem durch entsprechende Wahl der Beschaffenheit und der Abmessungen der beiden schallweichen Schichten 4a, 4b, die vorzugsweise aus einem hochwertigen Gummi bestehen und mittels einem Klebstoff mit dem betreffenden Flügelstück 32a bzw. 32b und dem Seitenteil 22a bzw. 22b verbunden sind.The installed noise protection device extends one connected mechanical system to a vibration system with at least one resonance frequency below the range of frequencies of interfering sound components lies, which arise when moving the moving part can. The vibration system is tuned by appropriate choice of quality and dimensions of the two soundproof layers 4a, 4b, which are preferably consist of a high quality rubber and by means of an adhesive with the relevant wing piece 32a or 32b and the side part 22a and 22b are connected.

Die Resonanzfrequenz des Schwingungssystems ergibt sich aus der Wurzel der Federkonstante der Schallschutzvorrichtung 1 geteilt durch die Wurzel der Masse des daran befestigten Systems. Vorzugsweise wird vorgesehen, dass die entstehende Flächenpressung der schallweichen Schichten 4a, 4b im Bereich von 2 kg/cm2 bis 4 kg/cm2 liegt.The resonance frequency of the vibration system results from the root of the spring constant of the soundproofing device 1 divided by the root of the mass of the system attached to it. It is preferably provided that the resulting surface pressure of the soundproof layers 4a, 4b is in the range from 2 kg / cm 2 to 4 kg / cm 2 .

Durch die Wahl eines schallweichen Materials für die Schichten 4a, 4b ergeben sich an den Übergängen zwischen den schallweichen Schichten 4a, 4b und den schallharten Flügelstücken 32a, 32b sowie den schallharten Seitenteilen 22a bzw. 22b zwei Reflexionsstellen an denen ausserhalb des Resonanzbereichs des Schwingungssystems liegende Schallwellen reflektiert werden, so dass durch die Schallschutzvorrichtung eine doppelte akustische Isolation des mechanischen Systems bewirkt wird. Die Grösse der Reflexion hängt dabei vom Verhältnis der Schallhärten bzw. der Schallwiderstände der an die Reflexionsstelle angrenzenden Materialien, der Wellenlänge und der Schalldichte ab. Stoffe mit hohem Schallwiderstand sind schallhart. Stoffe mit geringem Schallwiderstand sind schallweich. Der Schallwiderstand bzw. die Schallhärte ergibt sich dabei aus dem Produkt der Materialdichte und der Ausbreitungsgeschwindigkeit des Schalls innerhalb dem betreffenden Material.By choosing a soundproof material for the Layers 4a, 4b result at the transitions between the reverberant layers 4a, 4b and the reverberant layers Wing pieces 32a, 32b and the reverberant side parts 22a and 22b two reflection points on the outside of the resonance range of the vibration system Sound waves are reflected, so that through the soundproofing device a double acoustic isolation of the mechanical system is effected. The size of the Reflection depends on the ratio of sound hardness or the sound resistances of those adjacent to the reflection point Materials, the wavelength and the sound density from. Fabrics with high sound resistance are sound-hard. Fabrics with low noise resistance are soft as sound. The Sound resistance or sound hardness results from the product of the material density and the speed of propagation of the sound within that Material.

Die mit dem Mittelstück 3 verbundenen Flügelstücke 32a, 32b und die mit den Winkelelementen 2a, 2b verbundenen Seitenteile 22a, 22b sind vorzugsweise derart gegeneinander geneigt, dass die schallweichen Schichten 4a, 4b bei einer Auslenkung des Mittelstücks 3 in Richtung der Schwerkraft gleichzeitig auf Scherung und auf Druck belastet werden. Durch Scherbewegungen können tieffrequente Schwingungen hoher Amplitude ausgeführt werden. Durch gleichzeitigen Druck wird das schallweiche Material in der vorgegebenen Form gehalten und ferner ein Ablösen (z.B. Abscheren) der Schichten 4a, 4b verhindert. Die in Fig. 1 gezeigte Vorrichtung erlaubt daher die Verwendung von elastischen Materialien mit geringem Schallwiderstand.The wing pieces 32a connected to the middle piece 3, 32b and those connected to the angle elements 2a, 2b Side parts 22a, 22b are preferably against each other in this way inclined that the soundproof layers 4a, 4b with a deflection of the center piece 3 in the direction of Gravity at both shear and pressure be charged. Shear movements can cause low-frequency High amplitude vibrations are performed. By pressing simultaneously, the soundproof material becomes kept in the specified form and further a detachment (e.g. shearing) of the layers 4a, 4b prevented. In the 1 therefore allows use of elastic materials with low noise resistance.

In Fig. 2 sind die wesentlichen Abmessungen (Höhen h, Breiten b, Längen 1 und Dicken d) der in den Indizes bezeichneten Elemente der Schallschutzvorrichtungen zeichnerisch hervorgehoben. Dabei ist ersichtlich, dass das Mittelstück 3 und die Winkelelemente 2a, 2b in Richtung der Schwerkraft derart gegeneinander verschoben sind, dass beim Auftreten von Schwingungen das Mittelstück 3 nicht an den Montagekörper und die Winkelelemente 2a, 2b nicht an die Schiene 5 anstossen können. Die Flügelstücke 32a, 32b und die Seitenteile 22a bzw. 22b sind in Bezug auf die Richtung der Schwerkraft stark geneigt (in der beispielsweisen Ausgestaltung um 30° bzw. 35°), so dass bei einer Belastung der Schallschutzvorrichtung entsprechend hohe Kraftvektoren entstehen, durch die die schallweichen Schichten 4a, 4b auf Scherung und Druck belastet werden.2 the essential dimensions (heights h, Widths b, lengths 1 and thicknesses d) of those in the indices designated elements of the soundproofing devices in the drawing highlighted. It can be seen that the Center piece 3 and the angle elements 2a, 2b in the direction gravity are shifted against each other in such a way that if vibrations occur, the center piece 3 does not turn on the mounting body and the angle elements 2a, 2b not can hit the rail 5. The wing pieces 32a, 32b and the side parts 22a and 22b are with respect to FIGS Direction of gravity strongly inclined (in the example Design by 30 ° or 35 °), so that with a The load on the soundproofing device is correspondingly high Force vectors arise through which the sound-soft Layers 4a, 4b are subjected to shear and pressure.

Durch eine Neigung bzw. ein gegenseitiges Überlappen der Seitenteile 22a bzw. 22b und der Flügelstücke 32a, 32b kann zudem bewirkt werden, dass die Flügelstücke 32a, 32b des Mittelstücks 3 nach einem Schmelzen der schallweichen Schichten 4a, 4b durch die Seitenteile 22a bzw. 22b der Winkelelemente 2a, 2b gehalten werden, so dass das gegebenenfalls mit einem schweren beweglichen Teil versehene mechanische System auch im Brandfall mit dem Montagekörper verbunden bleibt.By an inclination or a mutual overlap of the Side parts 22a and 22b and the wing pieces 32a, 32b can also be caused that the wing pieces 32a, 32b of the middle piece 3 after melting the sound-soft Layers 4a, 4b through the side parts 22a and 22b of the Angle elements 2a, 2b are held, so that if necessary with a heavy moving part mechanical system even in the event of fire with the assembly body stays connected.

Ein Ablösen der schallweichen Schichten 4a, 4b während der Belastung kann ferner weitgehend verhindert werden, indem ein bevorzugter Verlauf der Schichten 4a, 4b an deren Enden gewählt wird. Dabei wird vorzugsweise ein stetig gegen die Auflageflächen konvergierender Verlauf gewählt, so dass unter Belastung entlang den schallweichen Schichten 4a, 4b ein gleichmässiger Spannungsverlauf resultiert. Das Material der schallweichen Schichten 4a, 4b liegt vorzugsweise derart an den mit dem Mittelstück 3 verbundenen Flügelstücken 32a, 32b und den mit den Winkelelementen 2a, 2b verbundenen Seitenteilen 22a, 22b an, dass sich die Enden der schallweichen Schichten 4a, 4b, vorzugsweise dem Verlauf der Form eines Zylinders folgend, praktisch bis zum Abschluss stetig verjüngen. Bei der Herstellung, die bevorzugt durch Vulkanisieren erfolgt, werden die Gummischichten daher der Einfachheit halber durch Körper begrenzt, die die Form eines Zylinders aufweisen (siehe Fig. 1, Kreise k1 und k2).Detachment of the soundproof layers 4a, 4b during the Stress can also be largely prevented by a preferred course of the layers 4a, 4b on their Ends is chosen. It is preferably a steady one chosen course converging against the contact surfaces, so that under load along the sound-proof Layers 4a, 4b have a uniform voltage profile results.
