Abstract

An apparatus for sealing an automatic elevator door against sound closes the small air gaps between a door post and a door leaf rear edge, between an abutment and the door leaf top edge, between abutting front edges of door leaves, between an inner door leaf front edge and outer door leaf rear edge in the case of telescopic doors, and between a door sill and a door leaf bottom edge. A post seal utilizes an elastic strip seal to close the post air gap. An abutment seal utilizes a sliding brush seal to close the abutment air gap. A door sill seal utilizes a labyrinth seal to close the sill air gap. A door edge seal utilizes a brush seal to close the front edge air gap. These seals close all the air gaps around the door leaves when the door is closed to prevent the ingress of sound of the noises produced mechanically outside the car.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung für eine Türabdichtung gegen Schall bei Aufzugskabinen mit automatischen Türen bestehend aus horizontal bewegten Türflügeln, welche oben mit Rollen und Schiene geführt und aufgehängt sind und unten in der Nut einer Türschwelle mittels Gleit-Führungsstücken geführt sind, wobei die Türflügel von einem Türantrieb via Übertragungsmechanik bewegt werden.The present invention relates to a device for a door seal against sound in elevator cars with automatic doors consisting of horizontally moving door leaves, which are guided and suspended at the top with rollers and rails and are guided at the bottom in the groove of a door sill by means of sliding guide pieces, the door leaves from a door operator can be moved via transmission mechanics.

Bei schnellaufenden Aufzugskabinen besteht das Problem der Schalldämmung, weil mit der Zunahme der Fahrgeschwindigkeit die im Schacht produzierten Fahr- und Luftgeräusche progressiv zunehmen, durch jede Öffnung in das Kabineninnere dringen und so den Fahrkomfort schmälern. Übliche Schalldämmungen mit Dämmstoffüllungen bei doppelwandigen Wänden und Türen, sowie leise arbeitende Lüftungssysteme vermögen zusammen mit Vibrationsdämpfungseinrichtungen eine entsprechende Wirkung zu erzielen. Akustikexperimente zeigen aber, dass kleinste Öffnungen sehr viel Schall durchlassen. Auf eine Tür bezogen heisst das, dass ein Türspalt von beispielsweise einem Prozent des ganzen Türöffnungsquerschnittes ein Drittel bis gegen die Hälfte eines ausserhalb dieser Tür erzeugten Schallvolumens auf die andere Seite, also in das Kabineninnere durchlässt. Bei einer automatischen Kabinentür hat es nun zwangsläufig eine Anzahl solcher Durchlässe in Form von kleinen Luftspalten zwischen bewegten und festen Teilen. Diese müssen vorhanden sein, um direkte Reibkontakte zu vermeiden. Solche Luftspalte sind an folgenden Stellen vorhanden: unten zwischen Türschwelle und unteren Türflügelkanten, seitlich zwischen Türflügelfläche und Eingangsseitenpfosten, zwischen zwei Türflügeln bei Teleskoptüren und oben zwischen Eingangskämpfer und Türflügeloberteil. Das Problem lässt sich teilweise lösen, indem mit engen Toleranzen und sehr genauer Fertigung und Montage gearbeitet wird, um diese Luftspalte auf ein Mindestmass zu reduzieren. Das ist eine teure Methode und befriedigt im Effekt doch nicht ganz.With high-speed elevator cars, there is the problem of soundproofing, because as the driving speed increases, the driving and air noise produced in the shaft increases progressively, penetrate the interior of the car through every opening and thus reduce driving comfort. Usual sound insulation with insulation fillings for double-walled walls and doors, as well as quietly working ventilation systems, together with vibration damping devices, can achieve a corresponding effect. Acoustic experiments show, however, that the smallest openings allow a lot of sound to pass through. In relation to a door, this means that a door gap of, for example, one percent of the entire door opening cross-section allows a third to half of a sound volume generated outside this door to pass through to the other side, i.e. into the interior of the cabin. In the case of an automatic cabin door, there is now inevitably a number of such passages in the form of small air gaps between moving and fixed parts. These must be present to avoid direct frictional contacts. Such air gaps are present at the following locations: below between the door sill and the lower edge of the door leaf, laterally between the door leaf surface and the entrance side mullion, between two door leaves on telescopic doors and above between the entrance fighter and the upper part of the door leaf. The problem can be partially solved by working with tight tolerances and very precise manufacturing and assembly in order to reduce these air gaps to a minimum. This is an expensive method and the effect is not entirely satisfactory.

Aus der US-Patentschrift Nr. 3,425,162 ist ersichtlich, dass diesem Problem üblicherweise keine Beachtung geschenkt wird und demzufolge diese Luftspalte gar nicht abgedichtet werden. In den Figuren 1 bis 5 dieser Patentschrift sind die für Schall grossen Durchlässe bei den eingangs erwähnten Stellen gut erkennbar.From US Pat. No. 3,425,162 it can be seen that this problem is usually ignored and consequently these air gaps are not sealed at all. In Figures 1 to 5 of this patent, the large passages for sound at the points mentioned above are clearly visible.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung zu schaffen, welche die genannten Nachteile nicht aufweist und die Luftspalte zwischen Tür und Kabine eliminiert.The present invention has for its object to provide a device which does not have the disadvantages mentioned and eliminates the air gaps between the door and the cabin.

Diese Aufgabe wird durch die in den Ansprüchen gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in the claims.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die verschiedenen Luftspalte bei geschlossener Kabinentür nicht mehr vorhanden sind bzw. sich nicht mehr nachteilig auswirken und dass eine entsprechende Vorrichtung allenfalls noch nachträglich eingebaut werden kann.The advantages achieved by the invention are essentially to be seen in the fact that the various air gaps are no longer present when the cabin door is closed, or no longer have a disadvantageous effect, and that a corresponding device can, if need be, be retrofitted.

There is a fighter seal 10 at the top of the door leaves 3 and a vertical post seal 7 at the rear edge of the door leaves 3. A threshold air gap is designated by 11.

Das Querschnittsbild der Figur 2 zeigt auf den Eingangsseiten je einen Seitenpfosten 1.1 mit der vertikalen Pfostendichtung 7, die Türschwelle 5 mit einer Führungsnut 5.1 und einen Türluftspalt 9 zwischen den Türflügeln 3 und den festen Teilen der Kabine 1.The cross-sectional view in FIG. 2 shows a side post 1.1 with the vertical post seal 7, the door sill 5 with a guide groove 5.1 and a door air gap 9 between the door leaves 3 and the fixed parts of the cabin 1 on the input sides.

Die Figur 3 zeigt die Einzelheiten der vertikalen Pfostendichtung 7. Diese besteht aus einem, seitwärts am Pfosten 1.1 befestigten Dichtungsträger 7.2 und einem elastischen Dichtungsprofil 7.1, welches einen Pfostenluftspalt 9.1 zwischen Türflügel 3 und Pfosten 1.1 schliesst.FIG. 3 shows the details of the vertical post seal 7. This consists of a seal carrier 7.2 fastened laterally on the post 1.1 and an elastic sealing profile 7.1, which closes a post air gap 9.1 between the door leaf 3 and the post 1.1.

In der Figur 4 wird die Kämpferdichtung 10 gezeigt, welche aus einem auf der oberen Stirnseite des Türflügels 3 befestigten horizontalen Dichtungsträger 10.2, einem Borstenträger 10.1 und einer Borstenreihe 10.3 besteht, wobei letzterer an der vertikalen Aussenfläche eines Winkelprofils 1.3 anliegt. Das Winkelprofil 1.3 befindet sich auf der horizontalen Oberseite eines Kämpfers 1.2. Mit 9.2 ist ein Kämpferluftspalt bezeichnet, welcher von oben her mit der gleitenden Kämpferdichtung 10 geschlossen wird. Die Türflügelaufhängungen 4 bestehen je aus einem Support 4.1, einem Rollenbolzen 4.3 und einer Rolle 4.2, welche auf der Schiene 8 läuft.In Figure 4, the fighter seal 10 is shown, which consists of a horizontal seal carrier 10.2 fastened on the upper end face of the door leaf 3, a bristle carrier 10.1 and a row of bristles 10.3, the latter resting on the vertical outer surface of an angular profile 1.3. The angle profile 1.3 is located on the horizontal top of a fighter 1.2. 9.2 denotes a fighter air gap, which is closed from above with the sliding fighter seal 10. The door leaf suspensions 4 each consist of a support 4.1, a roller pin 4.3 and a roller 4.2, which runs on the rail 8.

Die Figur 5 zeigt im Querschnitt die Einzelheiten der Türschwellendichtung 6. Im Türflügel 3 ist an der Unterseite am horizontalen Teil eines doppelwinkligen internen Distanzprofiles 3.2 ein Trägerwinkel 3.3 mit seinem kurzen Schenkel befestigt. Am langen Schenkel des Trägerprofils 3.3 ist eine Dichtplatte 6.1 montiert, welche ihrerseits nutfüllende Führungs-Gleitstücke 6.2 trägt. Die Türschwelle 5 hat eine Trittfläche 5.2 und darin eine Führungsnut 5.1, welche vom Führungs-Gleitstück 6.2 und der Dichtplatte 6.1 nicht ganz auf den Grund ausgefüllt wird, so dass am Nutgrund ein Zwischenraum 6.3 verbleibt. Unterhalb der Führungsnut 5.1 ist eine T-Nut 5.3 und das rechte untere Ende der Schwelle 5 hat eine weitere T-Nut 5.4. Beim Türflügel 3 sind die Aussenwände mit 3.5 und eine Schalldämmfüllung mit 3.4 bezeichnet.FIG. 5 shows in cross section the details of the door sill seal 6. In the door leaf 3, a carrier bracket 3.3 is fastened with its short leg to the underside of the horizontal part of a double-angled internal spacer profile 3.2. On the long leg of the carrier profile 3.3, a sealing plate 6.1 is mounted, which in turn carries groove-filling guide sliders 6.2. The door sill 5 has a step surface 5.2 and therein a guide groove 5.1, which is not completely filled to the bottom by the guide slide 6.2 and the sealing plate 6.1, so that a gap 6.3 remains at the bottom of the groove. Below the guide groove 5.1 is a T-groove 5.3 and the lower right end of the threshold 5 has another T-groove 5.4. In the case of door leaf 3, the outer walls are denoted by 3.5 and a sound insulation panel by 3.4.

Die Figur 6 zeigt eine Seitenansicht der Türschwellendichtung 6. Bei der Türschwelle 5 ist ein Seitenteil der Führungsnut 5.1 aufgeschnitten und gibt direkte Sicht auf die über die ganze Türflügelbreite durchgehende Dichtplatte 6.1 und auf ein darauf befestigtes Führungs-Gleitstück 6.2. Es ist ferner zwischen dem Nutgrund und der Unterseite der Dichtplatte 6.1 der Zwischenraum 6.3 sichtbar, welcher auf seiner ganzen Länge gleich gross ist. Der Schwellenluftspalt 11 ist der Zwischenraum zwischen der Trittfläche 5.2 und den Unterkanten der Aussenwände 3.5 der Türflügel 3. Die Vorderkante der Türflügel 3 trägt die vertikale Türkantendichtung 3.1.FIG. 6 shows a side view of the door sill seal 6. In the door sill 5, a side part of the guide groove 5.1 is cut open and gives a direct view of the sealing plate 6.1 which extends over the entire width of the door leaf and of a guide slider 6.2 fastened thereon. It is also visible between the groove base and the underside of the sealing plate 6.1, the space 6.3, which is the same size over its entire length. The threshold air gap 11 is the space between the tread surface 5.2 and the lower edges of the outer walls 3.5 of the door leaf 3. The front edge of the door leaf 3 carries the vertical door edge seal 3.1.

Die Figur 7 zeigt das Prinzip einer doppelten Schwellendichtung 6, in dem heruntergezogene Aussenwände 3.5 des Türflügels 3 am unteren Ende je eine Dichtplatte 6.1.1 und 6.1.2 bilden, an denen wiederum Führungs-Gleitstücke 6.2 angebracht sind. Die Türschwelle 5 weist eine erste Führungsnut 5.1.1 und eine zweite Führungsnut 5.1.2 auf und es sind Zwischenräume 6.3.1 und 6.3.2 vorhanden.FIG. 7 shows the principle of a double threshold seal 6, in which pulled-down outer walls 3.5 of the door leaf 3 each form a sealing plate 6.1.1 and 6.1.2 at the lower end, on which in turn guide slides 6.2 are attached. The door sill 5 has a first guide groove 5.1.1 and a second guide groove 5.1.2 and there are gaps 6.3.1 and 6.3.2.

Die Figur 8 zeigt die Einzelheiten der vertikalen Türkantendichtungen 3.1. Diese sind vor der inneren Vorderkante an den Kabinentürflügeln 3 im Zwischenraum zwischen den Schachttürflügeln 3.2 und den Kabinentürflügeln 3 angebracht. Sie bestehen je aus einem Borstenträger 3.6 und einer Borstenreihe 3.5. Bei geschlossener Tür durchdringen sich die Borstenreihen 3.5 gegenseitig und bewirken dadurch einen schallhemmenden Verschluss.FIG. 8 shows the details of the vertical door edge seals 3.1. These are attached in front of the inner front edge on the cabin door wings 3 in the space between the shaft door wings 3.2 and the cabin door wings 3. They each consist of a bristle holder 3.6 and a row of bristles 3.5. When the door is closed, the rows of bristles 3.5 penetrate one another and thereby effect a sound-proof closure.

Die vorstehend beschriebene Einrichtung arbeitet wie folgt: Aufgrund der mechanischen Gegebenheiten werden vier verschiedene Dichtungstypen verwendet, nämlich eine vertikale Pfostendichtung 7 mit einem aufliegenden elastischen Dichtungsprofil 7.1, eine Gleitborstendichtung für die Kämpferdichtung 10, eine Labyrinthdichtung für die Türschwellendichtung 6 und eine vertikale Türkantendichtung mit Kontaktborsten. Die Pfostendichtung 7 hat ein weiches, elastisches und in der Geschlossenstellung der Tür ein an der Seitenfläche des Pfostens 1.1 voll anliegendes Dichtungsprofil 7.1, welches den vertikalen Luftspalt 9.1 verschliesst. Die Borstenreihe 10.1 der horizontalen Kämpferdichtung 10 ist schräg nach unten gerichtet, wobei durch die schräge Auflage der Borsten an der vertikalen Gleitfläche des Winkels 1.3 die Elastizität der Borsten erst richtig ausgenützt wird. Die elastische Vorspannung und somit der Aufliegedruck der Gleitborsten bei der Kämpferdichtung 10 ist relativ klein und stellt keine speziellen Anforderungen an das Borstenmaterial und die Gleitfläche.The device described above works as follows: Due to the mechanical conditions, four different types of seals are used, namely a vertical post seal 7 with an elastic sealing profile 7.1 lying thereon, a sliding bristle seal for the fighter seal 10, a labyrinth seal for the door sill seal 6 and a vertical door edge seal with contact bristles. The post seal 7 has a soft, elastic and, in the closed position of the door, a sealing profile 7.1 which lies fully against the side face of the post 1.1 and which closes the vertical air gap 9.1. The row of bristles 10.1 of the horizontal fighter seal 10 is directed obliquely downward, the elasticity of the bristles being properly utilized by the oblique support of the bristles on the vertical sliding surface of the angle 1.3. The elastic preload and thus the contact pressure of the sliding bristles in the fighter seal 10 is relatively small and makes no special demands on the bristle material and the sliding surface.

Die Türschwellendichtung 6 ist als Labyrinthdichtung ausgebildet. Die auf der ganzen Breite eines Türflügels 3 durchgehende Dichtplatte 6.1 lässt im Nutgrund der Führungsnut 5.1 nur noch einen ganz kleinen Spalt von beispielsweise 0,5 bis 1 mm frei (Zwischenraum 6.3). Von aussen eindringende Schallwellen müssen einen U-förmigen Umweg machen, durch den Zwischenraum 6.3 schlüpfen und werden am Ende noch teilweise vom hohlen Unterteil des Türflügels 3 absorbiert (Fig. 5). Eine praktisch vollständige Sperre für Schallwellen wird mit der Doppeldichtung gemäss Fig. 7 erzielt. Es sind bei dieser Anordnung zwei Labyrinthdichtungen hintereinander, also in Serie vorhanden.The threshold seal 6 is designed as a labyrinth seal. The continuous sealing plate 6.1 over the entire width of a door leaf 3 only leaves a very small gap of, for example, 0.5 to 1 mm in the groove base of the guide groove 5.1 (intermediate space 6.3). Sound waves penetrating from the outside must make a U-shaped detour, slip through the intermediate space 6.3 and, in the end, are still partially absorbed by the hollow lower part of the door leaf 3 (FIG. 5). A practically complete blockage for sound waves is achieved with the double seal according to FIG. 7. With this arrangement there are two labyrinth seals one behind the other, i.e. in series.

Alle vier Dichtsysteme (6, 7, 10 und 3.1) zusammen decken die bei einer automatischen Tür vorhandenen Luftspalte 9.1, 9.2 und 11 vollständig ab und lassen bei geschlossener Tür kaum mehr ausserhalb der Kabine erzeugte Geräusche in diese eindringen. Die Pfostendichtung 7 schliesst den Pfostenluftspalt von der Türschwelle 5 bis hinauf unter die Kämpferdichtung 10 und diese wiederum deckt den gesamten Kämpferluftspalt 9.2 ab.All four sealing systems (6, 7, 10 and 3.1) together completely cover the air gaps 9.1, 9.2 and 11 present in an automatic door and hardly let any noise generated outside the cabin penetrate into it when the door is closed. The post seal 7 closes the post air gap from the door sill 5 up to below the fighter seal 10 and this in turn covers the entire fighter air gap 9.2.

Das Prinzip der Labyrinthdichtung für die Schwellendichtung 6 wird einer berührenden Dichtung deshalb vorgezogen, weil in diesem Bereich mit Schmutz und Fremdkörpern aller Art zu rechnen ist. Die Wirkung der Schwellendichtung 6 lässt sich noch weiter vergrössern, wenn, ausser der Verdoppelung gemäss Fig. 7, die Führungs-Gleitstücke 6.2 verlängert oder/und in grösserer Anzahl vorgesehen werden.The principle of the labyrinth seal for the threshold seal 6 is preferred to a contact seal because dirt and foreign bodies of all kinds can be expected in this area. The effect of the threshold seal 6 can be further increased if, in addition to the doubling according to FIG. 7, the guide sliders 6.2 are extended and / or provided in a larger number.

In einer Weiterbildung gemäss Figur 9 lässt sich die beschriebene Einrichtung auch für Teleskoptüren verwenden. Es sind dann die Kämpferdichtung 10, die vertikale Pfostendichtung 7 und die Schwellendichtung 6 je zweimal vorhanden. Die zweite vertikale Pfostendichtung 7 ist an einem äusseren Kabinentürflügel angebracht und liegt dann im geschlossenen Zustand der Tür an einem seitlich vorstehenden Dichtblech 14 an, welches an der Vorderkante des inneren Türflügels 12 angebracht ist. Die beiden anderen Dichtsysteme 10 und 6 sind genau gleich angeordnet wie bei der einfachen Tür und sind deshalb nicht nochmals dargestellt.In a further development according to FIG. 9, the device described can also be used for telescopic doors. There are then the fighter seal 10, the vertical post seal 7 and the threshold seal 6 twice available. The second vertical post seal 7 is attached to an outer cabin door leaf and then lies in the closed state of the door on a laterally projecting sealing plate 14 which is attached to the front edge of the inner door leaf 12. The two other sealing systems 10 and 6 are arranged exactly the same as in the simple door and are therefore not shown again.

Das Prinzip der vorstehend beschriebenen kombinierten Dichtsysteme lässt sich auch für automatische und handbetätigte Schiebetüren an Strassen- und Schienenfahrzeugen anwenden.The principle of the combined sealing systems described above can also be used for automatic and manually operated sliding doors on road and rail vehicles.
