Description

Die Erfindung betrifft eine Einrichtung zum Abdichten eines Spaltes zwischen Kabinentür und Kabinenwand einer Aufzugskabine gemäss der Definition der Patentansprüche.The invention relates to a device for sealing a gap between the car door and cabin wall of an elevator car according to the definition of the claims.

Bei schnelllaufenden Aufzugskabinen besteht das Problem der Schalldämmung, weil mit steigender 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 Dämmstofffüllungen 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 Spalten zwischen bewegten und festen Teilen. Diese müssen vorhanden sein, um direkte Reibkontakte zu vermeiden. Solche Spalte sind an folgenden Stellen vorhanden: zwischen Türschwelle und unteren Türflügelkanten, seitlich zwischen Türflügelfläche und Eingangsseitenpfosten, zwischen zwei Türflügeln bei Teleskoptüren und zwischen Eingangskämpfer und Türflügeloberteil. Das Problem lässt sich teilweise lösen, indem mit engen Toleranzen und sehr genauer Fertigung und Montage gearbeitet wird, um diese Spalte auf ein Mindestmass zu reduzieren. Das ist eine teure Methode und befriedigt im Effekt nicht.In high-speed elevator cars there is the problem of sound insulation, because with increasing driving speed, the driving and air noise produced in the shaft progressively increase, penetrate through each opening in the cabin interior and thus reduce the ride comfort. Conventional sound insulation with Dämmstofffüllungen in double-walled walls and doors, and quietly working ventilation systems are able to achieve a corresponding effect together with vibration damping devices. However, acoustic experiments show that the smallest openings allow a lot of sound to pass through. With reference to a door, this means that a door gap of, for example, one percent of the entire door opening cross section lets through one third to half the volume of sound generated outside this door to the other side, ie into the interior of the cabin. In an automatic car door, it inevitably has a number of such passages in the form of small gaps between moving and fixed parts. These must be present in order to avoid direct frictional contacts. Such gaps are present at the following points: between the threshold and the lower edge of the door, between the side of the door and the side of the door, between two doors in the case of telescopic doors and between the entrance fender and the upper part of the door. The problem can be partially solved by working with tight tolerances and very accurate manufacturing and assembly to minimize this gap. This is an expensive method and does not satisfy in effect.

Aus der US-Patentschrift Nr. 3,425,162 ist ersichtlich, dass diesem Problem üblicherweise keine Beachtung geschenkt wird und demzufolge diese Spalte 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 the U.S. Patent No. 3,425,162 It can be seen that this problem is usually ignored and consequently these gaps are not sealed at all. In the FIGS. 1 to 5 This patent clearly recognizes the sound passages at the points mentioned above.

Das Patent EP 0418510 betrifft eine Vorrichtung für eine Türabdichtung gegen Schall bei Aufzugskabinen mit automatischen Türen. Diese Türen weisen zwischen Türpfosten und Türflügel, Kämpfer und Türflügel, innerem Türflügel und äusserem Türflügel bei Teleskoptüren, und zwischen Türflügelunterseite und Türschwelle normalerweise kleine Spalte auf, um bei Türbewegungen zwischen bewegten und festen Teilen eine Berührung zu vermeiden. Zum Dichten und Decken dieser Spalte sind an den Türflügeln im Geschlossenzustand der Tür vertikale, einen Spalt schliessende Pfostendichtungen, auf der Oberseite der Türflügel gleitende Kämpferdichtungen, in der Türschwelle Schwellendichtungen und vertikale Türkantendichtungen an den Vorderkanten der Türflügel vorhanden. Diese Dichtungen schliessen alle Spalte bei geschlossener Tür ringsherum ab und verhindern so weitgehend das Eindringen von ausserhalb der Kabine mechanisch erzeugten Geräuschen.The Patent EP 0418510 relates to a device for a door seal against sound in elevator cars with automatic doors. These doors normally have small gaps between door jambs and door leaves, fighters and door leaves, inner door leaves and outer doors of telescopic doors, and between the lower door sill and door sill to avoid contact with door movements between moving and fixed parts. To seal and cover this column, the doors are in the closed state of the door vertical, a gap closing post seals, on the top of the door sliding fender seals, in the threshold door seals and vertical edge seals on the front edges of the door wings available. These seals close all gaps around with the door closed and thus largely prevent the penetration of outside the cabin mechanically generated noise.

Ein Nachteil dieser bekannten Einrichtung liegt im grossen mechanischen Aufwand und den damit verbundenen grossen Herstellungskosten. Ein weiterer Nachteil ist der hohe Aufwand an Einstell- und Unterhaltsarbeiten.A disadvantage of this known device is the great mechanical complexity and the associated high production costs. Another disadvantage is the high cost of adjustment and maintenance work.

JP 2001294388 offenbart ein expansibles kugelförmiges Körper und JP 10077186 offenbart drehbare Stahlplatten, welche die Aufzugskabine isolieren. Die Patentschrift JP 2001294388 zeigt eine Vorrichtung für eine Türabdichtung mit einer pneumatisch betätigbaren Dichtungsleiste. JP 2001294388 discloses an expansible spherical body and JP 10077186 discloses rotatable steel plates which insulate the elevator car. The Patent JP 2001294388 shows a device for a door seal with a pneumatically actuated sealing strip.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung zu schaffen, welche die genannten Nachteile nicht aufweist und Spalte zwischen Tür und Kabine weitgehend eliminiert. Insbesondere soll eine Dichtungseinrichtung mit einfachem Aufbau geschaffen werden, die unabhängig von der Türbewegung arbeitet.The present invention is based on the object to provide a device which does not have the disadvantages mentioned and largely eliminates gaps between the door and the cabin. In particular, a sealing device with a simple structure is to be created, which operates independently of the door movement.

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

Erfindungsgemäss umfasst eine Einrichtung zum Abdichten eines Spaltes zwischen Kabinentür und Kabinenwand einer Aufzugskabine während der Kabinenfahrt eine Dichtungsleiste, die mindestens zwei Wände aufweist, welche Wände vor dem Spalt reversibel spannbar sind.According to the invention, a device for sealing a gap between the car door and the car wall of an elevator car during the car trip comprises a sealing strip which has at least two walls, which walls can be reversibly tensioned in front of the gap.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass durch das Spannen der Wand die verschiedenen Spalte bei geschlossener Kabinentür nicht mehr vorhanden sind bzw. sich nicht mehr nachteilig auswirken und dass eine entsprechende Vorrichtung allenfalls noch nachträglich eingebaut werden kann. Vorteilhafterweise wird die Dichtungsleiste nur während der Fahrt aktiviert und die Wand vor dem Spalt gespannt.The advantages achieved by the invention are essentially to be seen in the fact that by clamping the wall, the various gaps are no longer present when the car door is closed or no longer have a disadvantageous effect and that a corresponding device may at most be retrofitted. Advantageously, the sealing strip is activated only while driving and the wall stretched in front of the gap.

Die Dichtungsleiste könnte ein elastischer Hohlkörper sein, welcher Hohlkörper durch Druckluft und/oder Vakuum beaufschlagbar ist. Die durch diese nicht mehr von der Erfindung erfasste Ausführung erreichten Vorteile bestehen darin, dass die Dichtung nur im geschlossenen Zustand aktiv gedichtet wird, dass sie bei der Türbewegung berührungsfrei ist, dass sie nur während der Fahrt im Eingriff ist (bei Bedarf nur ab einer bestimmten Geschwindigkeit) und dass sie somit keinen Einfluss auf die Türbewegung, den Schliessvorgang oder die Verriegelung der Türe hat.The sealing strip could be an elastic hollow body, which hollow body can be acted upon by compressed air and / or vacuum. The advantages achieved by this embodiment, which is no longer covered by the invention, are that the seal is actively sealed only in the closed state, that it is non-contact during the door movement, that it is engaged only while driving (if necessary only at a certain point) Speed) and that it thus has no influence on the door movement, the closing process or the locking of the door.

Nach einem Ausführungsbeispiel weist die Dichtungsleiste vorteilhafterweise Eisenstreifen und mindestens einen Elektromagnet auf, welcher elektrisch aktivierbar ist. Die durch diese Ausführung erreichten Vorteile sind darin zu sehen, dass durch den einfachen Aufbau der Dichtungseinrichtung grosse Ersparnisse an technischem Aufwand erzielt werden und dass durch den einfachen Aufbau eine minimale Störanfälligkeit gewährleistet ist. Ein weiterer Vorteil besteht darin, dass durch die Unabhängigkeit von der Türbewegung eine raschere Arbeitsweise der Dichtungseinrichtung möglich wird. Ein weiterer Vorteil besteht darin, dass die Wirksamkeit der Dichtungseinrichtung wesentlich verbessert wird.According to one embodiment, the sealing strip advantageously has iron strips and at least one electromagnet, which is electrically activatable. The advantages achieved by this embodiment can be seen in the fact that by the simple design of the sealing device large savings in technical complexity can be achieved and that a minimal susceptibility is ensured by the simple structure. Another advantage is that by the independence of the door movement a faster operation of the sealing device is possible. Another advantage is that the effectiveness of the sealing device is substantially improved.

Die Erfindung löst ein längst bestehendes Vorurteil der Fachwelt auf, nach welchem keine zusätzlichen Komponente an der Aufzugskabine angeordnet werden sollen, um Gewicht und Kosten zu sparen. In diesem spezifischen Fall werden aber Höhlkörper oder Elektromagnete um die Kabinenöffnung einer Aufzugskabine angeordnet. Es hat sich nun überraschend herausgestellt, dass diese Komponente leicht und kostengünstig sind, eine wesentliche Verbesserung des Fahrkomforts und eine merkwürdige Vereinfachung der mechanischen Aufbauten für Schalldämmung in Aufzugskabinen ermöglichen.The invention solves a long-standing prejudice of the art, according to which no additional component to be arranged on the elevator car in order to save weight and cost. In this specific case, however, hollow bodies or electromagnets are arranged around the cabin opening of an elevator car. It has now surprisingly been found that these components are lightweight and inexpensive, allow a substantial improvement in ride comfort and a remarkable simplification of the mechanical structures for sound insulation in elevator cars.

Im Folgenden wird die Erfindung anhand eines Ausführungsbeispiels näher erläutert, wobei Fig. 1 und Fig. 2 nicht von der Erfindung erfasst sind.In the following the invention will be explained in more detail with reference to an embodiment, wherein Fig. 1 and Fig. 2 not covered by the invention.

  • Fig. 2 a schematic cross-sectional view of a pressure-operated by compressed air sealing strip in pressureless and beaufschlagtem state,

  • Fig. 4b corresponds to Fig. 4a in the activated state.

In den Fig. 1 bis 4 ist mit 2 eine Kabinenwand und mit 3 eine Kabinentür einer Aufzugskabine 1 bezeichnet. In Fig. 1 ist eine aus elastischem Material aufgebaute Dichtungsleiste 4 um die Kabinenöffnung angeordnet. Die Dichtungsleiste 4 besteht aus einem oberen Teil und einem unteren Teil (in der Schwelle), die einen in der Fig. 2 dargestellten Querschnitt aufweisen. Gemäss Fig. 2 besteht die Dichtungsleiste 4 aus einem eine erste Wand 41 und eine zweite Wand 42 aufweisenden Hohlkörper 8, der sich ballonartig ausdehnt. Der zur Ausdehnung des Hohlkörpers 8 nötige Druck wird über einen Drückbehälter 6 von einer Druckquelle 7 erzeugt. Die Druckluftspeisung erfolgt beispielweise über folgende vier Variante:

  1. 1. Einen Kompressor, mit dem Vorteil des raschen Füllens des Behälters und mit dem Nachteil des Lärms.
  2. 2. Eine mechanische Pumpe, welche durch die Türbewegung betrieben wird, mit dem Vorteil der Laufruhe und dass kein zusätzlicher Motor oder Antrieb nötig ist. Die Kräfte für den Türantrieb/Schliesskraftbegrenzer werden verwendet, sodass pro Türbewegung nur ein Pumpvolumen zum Füllen des Druckbehälters zur Verfügung steht und der Behälter nur über Türbewegungen gefüllt wird.
  3. 3. Ausnutzen der Druckdifferenz vor und nach der Kabine bei schnellfahrenden Kabinen bzw. Unterdruck zwischen Kabine und Schachttüren.
  4. 4. Doppelwirkenden Kolben, welcher durch die Beschleunigungskräfte beim Anfahren und Bremsen betätigt wird.
In the Fig. 1 to 4 2 is a cabin wall and 3 is a car door of an elevator car 1. In Fig. 1 is a built-up of elastic material sealing strip 4 is arranged around the cabin opening. The sealing strip 4 consists of an upper part and a lower part (in the threshold), one in the Fig. 2 have shown cross-section. According to Fig. 2 the sealing strip 4 consists of a first wall 41 and a second wall 42 having hollow body 8, which expands like a balloon. The pressure necessary for the expansion of the hollow body 8 is generated by a pressure source 7 via a pressure container 6. The compressed air supply takes place, for example, via the following four variant:
  1. 1. A compressor, with the advantage of rapid filling of the container and with the disadvantage of noise.
  2. 2. A mechanical pump, which is operated by the door movement, with the advantage of smoothness and that no additional motor or drive is needed. The forces for the door drive / closing force limiter are used so that only one pumping volume is available per door movement for filling the pressure vessel and the container is filled only by door movements.
  3. 3. Taking advantage of the pressure difference before and after the cabin in fast-moving cabins or negative pressure between the cab and landing doors.
  4. 4. Double-acting piston, which is actuated by the acceleration forces when starting and braking.

In Fig. 1 ist die zweite Variante dargestellt. Die von der Druckquelle 7 verdichtete Luft gelangt in den Drückbehälter 6.In Fig. 1 the second variant is shown. The air compressed by the pressure source 7 reaches the pressure vessel 6.

Der in der Fig. 2 gezeigte Hohlkörper 8 ist in drucklosem Zustand derart bemessen, dass ein für die freie Öffnung und Schliessung der Kabinentüren notwendiger Abstand von der Kabinenwand 2 gewährleistet ist. Die während der Aufzugsfahrt über eine nicht dargestellte Öffnung im Hohlkörper 8 einströmende Druckluft 5 dehnt den elastischen Hohlkörper 8 gemäss Fig. 2 ballonartig aus, so dass er gegen die Kabinentür 3 gepresst wird und dabei den Spalt 11 zwischen der Kabinentür 3 und der Kabinenwand 2 druck- und schalldicht abdichtet.The Indian Fig. 2 shown hollow body 8 is dimensioned in a depressurized state such that a necessary for the free opening and closing of the car doors distance from the cabin wall 2 is ensured. The during the elevator ride via an opening, not shown in the hollow body 8 incoming compressed air 5 expands the elastic hollow body 8 according to Fig. 2 balloon-like, so that it is pressed against the car door 3 and thereby seals the gap 11 between the car door 3 and the cabin wall 2 pressure and soundproof.

Beim Halten der Aufzugskabine 1 an der Haltestelle wird der Hohlkörper 8 entlüftet. Die dem Material des Hohlkörpers 8 anhaftende Elastizität bringt diesen dabei wieder in die Ausgangsform gemäss der Fig. 2 zurück. Dadurch ist der Spalt zwischen Kabinentür und Kabinenwand wieder vorhanden, der eine einwandfreie und berührungsfreie Bewegung der Türflügel bei der Türöffnung und -Schliessung ermöglicht.When holding the elevator car 1 at the stop of the hollow body 8 is vented. The elastic material adhering to the material of the hollow body 8 brings it back into its original shape according to FIG Fig. 2 back. As a result, the gap between the car door and car wall is present again, which allows a perfect and non-contact movement of the door when opening and closing the door.

Sobald die Aufzugskabine 1 auf der Haltestelle eingefahren ist, bringt die Aufzugssteuerung Wegeventile elektromagnetisch von einer ersten, die Dichtungsleiste 4 mit dem Speisedruck beaufschlagende Stellung in eine zweite, die Dichtungsleiste 4 entlüftende Stellung. Die Aufzugssteuerung gibt die Türöffnung und -Schliessung der Aufzugskabine 1 bei der Haltestelle erst dann frei, wenn alle Druckschalter den Abschluss der Entlüftung melden.As soon as the elevator car 1 is retracted on the stop, the elevator control system transfers directional valves electromagnetically from a first position acting on the sealing strip 4 with the feed pressure into a second position venting the sealing strip 4. The elevator control releases the door opening and closing of the elevator car 1 at the stop only when all the pressure switches report the completion of the ventilation.

Anstelle der Entlüftung zur Atmosphäre könnte die Dichtungsleiste 4 vakuiert werden. In diesem Fall ist die Auslassöffnung der Wegeventile an die Saugleitung einer Vakuumquelle anzuschliessen. Die Vakuierung bewirkt eine raschere Abfahrbereitschaft der Dichtungsleiste 4.Instead of venting to the atmosphere, the weather strip 4 could be evacuated. In this case, connect the outlet opening of the directional control valves to the suction line of a vacuum source. The vacuum causes a faster Abfahrbereitschaft the sealing strip. 4

Ein Ausführungsbeispiel der Erfindung wird in Fig. 3 erläutert, wobei die Dichtungsleiste 4 nicht pneumatisch durch Druckluft, sondern elektromagnetisch durch einen Elektromagnet 9 betrieben wird.An embodiment of the invention is shown in FIG Fig. 3 explained, wherein the sealing strip 4 is not operated pneumatically by compressed air, but electromagnetically by an electromagnet 9.

In diesem Ausführungsbeispiel wird die flexible Dichtungsleiste 4 nicht an der Kabinenwand 2, sondern an der Kabinentür 3 angeordnet. In der Dichtungsleiste 4 sind zusätzlich Eisenstreifen 10 eingebettet, die in Wechselwirkung mit dem in dem Kabinentürrahmen angeordneten stabförmigen Elektromagnet 9 stehen, wenn die Kabinentüren 3 geschlossen sind.In this embodiment, the flexible sealing strip 4 is not arranged on the cabin wall 2, but on the car door 3. In the weather strip 4 iron strips 10 are additionally embedded, which are in interaction with the arranged in the car door frame rod-shaped electromagnet 9, if the car doors 3 are closed.

Wenn die Kabinentüre 3 bei der Wegfahrt der Aufzugskabine 1 geschlossen werden, wird der Elektromagnet 9 durch eine elektrische Spannung aktiviert, so dass attraktive elektromagnetische Kräfte zwischen dem Elektromagnet 9 und den Eisenstreifen 10 entstehen. Die Dichtungsleiste 4 wird dadurch dicht schliessend an die Kabinenwand 2 gezogen. Fig. 4b zeigt die Dichtungsleiste 4 in der aktivierten Stellung, wenn eine Spannung an dem Elektromagnet 9 angelegt wird, die Kabinentüre 3 geschlossen sind und die Aufzugskabine fährt. Fig. 4a zeigt die Dichtungsleiste 4 in der deaktivierten Stellung, wenn keine Spannung an dem Elektromagnet 9 angelegt wird und die Kabinentüre 3 geschlossen oder geöffnet werden während die Aufzugskabine am Stockwerkhalt steht.When the car door 3 is closed during the drive of the elevator car 1, the electromagnet 9 is activated by an electrical voltage, so that attractive electromagnetic forces between the electromagnet 9 and the iron strip 10 arise. The sealing strip 4 is thereby pulled tightly closing against the cabin wall 2. Fig. 4b shows the sealing strip 4 in the activated position when a voltage is applied to the solenoid 9, the car door 3 are closed and the elevator car moves. Fig. 4a shows the sealing strip 4 in the deactivated position when no voltage is applied to the solenoid 9 and the car doors 3 are closed or opened while the elevator car is at the floor stop.

Der stabförmige Elektromagnet 9 kann durch mehrere punktförmige Elektromagnete ersetzt werden. Durch den Eisenstab in der Dichtungsleiste 4 wird die Dichtungsleiste 4 steif genug um auf der ganzen Länge dicht anzuliegen. Der Elektromagnet 9 kann auch in den Türen sitzen und die Dichtungsleiste in der Kabinenwand. Die Steuerung des Elektromagnets erfolgt vorteilhafterweise über die Türsteuerung.The rod-shaped electromagnet 9 can be replaced by a plurality of punctiform electromagnets. By the iron rod in the sealing strip 4, the sealing strip 4 is stiff enough to lie tightly over the entire length. The solenoid 9 can also sit in the doors and the sealing strip in the cabin wall. The control of the electromagnet is advantageously carried out via the door control.

Bei Kenntnis der vorliegenden Erfindung stehen dem Fachmann vielfältige Möglichkeiten der Variation des gezeigten Ausführungsbeispiels zur Verfügung.With knowledge of the present invention, various possibilities of variation of the embodiment shown are available to the person skilled in the art.
