Abstract
Description
Schalldämmender, flexibler Schlauch. Sound-absorbing, flexible hose.
Die Erfindung betrifft einen schalldämmenden, flexiblen Schlauch mit einer äußeren Hülle aus Schaumstoft und einem innerhalb liegenden Gewebe.The invention relates to a sound-absorbing, flexible hose with an outer shell made of foam and an inner fabric.
Es sind schalidämmende, flexible Schläuche in der unterschiedlichsten Art bekannt. Diese werden als sogenannte Meterware hergestellt, wobei zur Schalldämmung offenporiger Schaumstoff oder Glaswolle verwendet wird. Dieses Material muß dann durch Umschweißen einer gesonderten Folie geschützt werden. An den Enden weisen diese Schläuche keinerlei'gesonderte Endabschlüsse, sondern einfach offene Schnittflächen auf. Die Befestigung erfolgt durch sogenannte Schlauchklemmen, Der Erfindung liegt die Aufgabe zugrunde, einen Schlauch der eingangs genannten Art zu schaffen, der bei guten Eigenschaften hinsichtlich der Schalldämpfung ein gutes Erscheinungsbild aufweist und darüber hinaus leicht und sicher verlegt, d.h. befestigt werden kann.There are sound-insulating, flexible hoses in the most varied Kind known. These are manufactured as so-called yard goods, whereby for sound insulation open-cell foam or glass wool is used. This material must then protected by welding a separate film. Point at the ends these hoses do not have any separate end terminations, but simply open cut surfaces on. The fastening is carried out by so-called hose clamps, the invention lies the task of creating a hose of the type mentioned above, which good appearance with good soundproofing properties and can also be laid, i.e. fastened, easily and safely.
Diese Aufgabe wird dadurch gelöst, daß die äußere Hülle aus einem einseitig geschlossen-porigen Schaumstoff mit einer dichten, einstückigen Außonschlcht oder -folie besteht, daß das Gewebe weitmaschig ist, und daß eine Verstärkung in Form eines Splraldahtos vorgesehen ist.This object is achieved in that the outer shell consists of a One-sided closed-pore foam with a dense, one-piece outer layer or film is that the fabric is wide-meshed, and that a reinforcement in Form of a Splraldahtos is provided.
Die äußere Hülle aus Schaumstoff mit der einstückigen dichten Außenschicht weist durch ihren Aufbau hervorragende Schalldämprungseigenschaften auf. Der Schall dringt durch das \verhältnismäßig weitmaschige Gewebe in den Sehaumstorrkörper ein und wird dort stark gedäapt. Die dichte, gschlossen Außenschicht stellt eine Schutzfolie gegen Eindringen von Feuchtigkeit und andere Medien dar. Der Spiraldraht sorgt für eine entsprechende Steifigkeit bei gleichzeitiger Flexibilität, so daß der Schlauch auch ait entsprechenden Krthnmungen verlegt werden kann.The outer shell made of foam with the one-piece, dense outer layer Due to its structure, it has excellent soundproofing properties. The sound penetrates through the relatively wide-meshed tissue into the hemiplegic body and is heavily dazed there. The dense, closed outer layer provides a protective film against ingress of moisture and other media. The spiral wire ensures a corresponding rigidity with simultaneous flexibility, so that the hose can also be laid with the appropriate Krthnmungen.
In besondere vorteilhafter Weise ist der Schlauch derart ausgebildet, daß an den Enden Endkappen befestigt sind, die den sauberen und inneren Schlauchmantel überragende Ringabschnitte aufweisen.In a particularly advantageous manner, the hose is designed in such a way that that end caps are attached to the ends, which the clean and inner hose jacket Have protruding ring sections.
Diese Endkappen erlauben eine Befestigung durch Aufstecken oder dergleichen an entsprechenden Rohrstutzen, ohne daß weitere Befestigungselemente wie Schlauchklemmen oder Federelemente erforderlich sind. Weiterhin ist das optische Erscheinungsbild durch diese Endkappen mit den überragenden Ringabschnitten sehr gut, da eine saubere und glatte Einheit entsteht. Auf den Rohrstutzen halten die vorzugsweise aus einem entsprechenden Kunststoff hergestellten und mit dem eigentlichen Schlauch verklebten Endkappen durch Reibung sehr gut.These end caps allow attachment by clipping or the like on the corresponding pipe socket without the need for further fastening elements such as hose clamps or spring elements are required. Furthermore, the visual appearance very good because of these end caps with the protruding ring sections, as a clean one and smooth unity is created. Hold on to the pipe socket, preferably from one corresponding plastic produced and glued to the actual hose End caps very good due to friction.
@er Spiraldr@at ist vorzugsweise mit verrottungsfestem @@erial überzogen. Dieses kann durch eine @unststoifbeschichtung erreicht werden.@er Spiraldr @ at is preferably covered with rot-proof @@ erial. This can be achieved with a plastic coating.
Als Material zur Herstellung der äußeren Hülle hat sich Polyurethanschaumstoff mit einer dichten äußeren Schicht als zweckmäßig herausgestellt.Polyurethane foam has proven to be the material used to manufacture the outer shell with a dense outer layer turned out to be useful.
Weitere Vorteile und Einzelheiten der Erfindung werden im folgenden unter Hinweis auf die Zeichnung anhand eines Ausführungsbelspieles näher erläutert.Further advantages and details of the invention are set out below explained in more detail with reference to the drawing based on an Ausführungsbelspieles.
Es zeigt: Fig. 1 eine Seitenansicht eines Endes eines Schlauches nach der Erfindung; Fig. 2 einen Längsschnitt durch einen Teil eines Schlauches nach der Erfindung im vergrößertem Maßstab; und Fig. 3 einen Querschnitt durch eine Endkappe des Schlauches der Fig. 1.It shows: FIG. 1 a side view of one end of a hose according to FIG the invention; Fig. 2 shows a longitudinal section through part of a hose according to the invention on an enlarged scale; and FIG. 3 shows a cross section through an end cap of the hose of FIG. 1.
Der in Fig. 1 dargestellte Schlauch besteht aus einer äußeren Hülle 1 aus Schaumstoff und aus Endkappen j, von denen eine gezeigt ist.The hose shown in Fig. 1 consists of an outer shell 1 made of foam and end caps j, one of which is shown.
Wie beim Betrachten der Fig. 2 deutlich wird, ist der Schaumstoff offenporig, wobei eine feste und dichte äußere Schicht 2 vorgesehen ist, die praktisch einen Foliencharakter hat.As can be seen from looking at Figure 2, the foam is open-pored, with a firm and tight outer layer 2 is provided, which is practical has a foil character.
Das Gewebe 5 ist verhältnismäßig weitmaschig. Es wird durch einen Spiraldraht 6 gestützt. Der Schall dringt durch die Maschen des Gewebes in den Schaumstoffkörper ein und wird dort gedämpft.The fabric 5 is relatively wide-meshed. It is through one Spiral wire 6 supported. The sound penetrates the foam body through the meshes of the fabric one and is muffled there.
Die aus entsprechend flexiblem Kunststoff hergestellten Endkappen werden mit dem Schlauch verklebt, so daß die Ringabschnitte 7 und 8 die entsprechenden Schlauchmäntel Aberragen und der Schlauch in dem Ringraum 4 liegt. Der Schlauch mit den beiden Endkappen hat ein glattes und sauberes äußeres Erscheinungabild, ohne daß im Bereich der Stirnflächen der offenporige Schaumstoffkörper sichtbar wird. Der innenliegende Ringabschnitt 8 wird zur Befestigung auf einen entsprechenden Rohrstutzen aurgesteckt und hält an diesem durch Klemmsitz, d.h. durch Reibung@kraft, ohne daß zusätzliche Schlauchklemmen oder der erforderlich werden.The end caps made of appropriately flexible plastic are glued to the hose so that the ring sections 7 and 8 the corresponding hose jackets protrude and the hose in the annular space 4 lies. The hose with the two end caps has a smooth and clean exterior Appearance without the open-pored foam body in the area of the end faces becomes visible. The inner ring portion 8 is for attachment to a corresponding pipe socket and holds on this by a press fit, i.e. by friction @ force, without the need for additional hose clamps or the will.
