Description

Aufzuganlage mit Aufzugkabine mit nachgiebiger Deckenkonstruktion  Elevator system with elevator cabin with flexible ceiling construction
Die vorliegende Erfindung betrifft eine Aufzugs anläge mit einer Aufzugkabine, die über eine nachgiebige Deckenkonstruktion verfügt. The present invention relates to an elevator anläge with an elevator car, which has a resilient ceiling construction.
Bei der Gestaltung einer Aufzugsanlage wird der optimalen Raumausnutzung hohe Priorität beigemessen. Darum wird angestrebt, den freien Schachtraum am oberen Schachtende oberhalb der Kabine möglichst klein zu halten. Normalerweise ist das Kabinendach zwecks Wartungs- und Servicearbeiten betretbar. Um zu verhindern, dass eine Person zwischen Kabinendach und Schachtkopf eingequetscht wird, fordern die Sicherheitsstandards unter anderem, einen Schutzraum von 0.6 x 0.8 x 0.5 m3. Dies heißt nichts anderes, als dass der Abstand zwischen der Wartungsfläche auf dem Kabinendach und dem Schachtkopf auf einer Fläche von 0.6 x 0.8 m2 nicht weniger als 0.5 m betragen darf, wenn sich die Kabine auf der obersten erreichbaren Position befindet. When designing a lift system, the optimal use of space is given high priority. Therefore, the aim is to keep the free shaft space at the upper shaft end above the cabin as small as possible. Normally, the canopy is accessible for maintenance and service. Among other things, safety standards require a shelter of 0.6 x 0.8 x 0.5 m 3 to prevent a person from being squeezed between the cabin roof and the shaft head. This means that the distance between the maintenance area on the cabin roof and the shaft head over an area of 0.6 x 0.8 m 2 must not be less than 0.5 m when the cabin is in the uppermost accessible position.
WO 2008/074168 AI zeigt eine Kabinenkonstruktion, mit welcher der Abstand zwischen der Kabine und dem oberen Schachtende auf unter 0.5 m reduziert wird. Dazu ist die Kabinendecke auf einer Grundfläche von mindestens 0.6 x 0.8 m2 nachgiebig ausgelegt. Diese Kabinendecke verfügt über ein Kabinendeckent- eil, das über eine perforierte Abbruchkante mit dem Rest der Kabinendecke verbunden ist. Diese Abbruchkante ist dabei dermaßen dimensioniert, dass beim Betreten des Kabinendeckenteils die Abbruchkante bricht und sich dadurch das Kabinendeckenteil in den Innenraum der Kabine absenkt. Dadurch wird der Sicherheitsraum zumindest teilweise in den Innenraum der Kabine verlagert. Folglich werden die Sicherheitsstandards auch bei Unterschreiten des Sicherheitsabstands von 0.5 m zwischen der Kabine und des oberen Schachtendes erfüllt. WO 2008/074168 AI shows a cabin construction with which the distance between the cabin and the upper shaft end is reduced to less than 0.5 m. For this purpose, the cabin ceiling is designed with a yield of at least 0.6 x 0.8 m 2 . This cabin ceiling has a cabin ceiling part which is connected to the rest of the cabin ceiling via a perforated demolition edge. This demolition edge is dimensioned so that when entering the cabin ceiling part, the demolition edge breaks and thereby lowers the cabin ceiling part in the interior of the cabin. As a result, the security room is at least partially shifted into the interior of the cabin. As a result, safety standards are met even if the safety distance of 0.5 m between the car and the upper shaft end is undershot.
Bei diesem Konzept wirkt sich jedoch die bleibende Beschädigung des Kabinendachs negativ aus. Denn wenn die Abbruchkante einmal gebrochen ist, muß das Kabinendach ersetzt werden. Diese Reparaturarbeiten sind relativ aufwendig und teuer. Zudem führen diese Arbeiten zu einem längeren Ausfall der Aufzugsanlage. Deswegen liegt der vorliegenden Erfindung die Aufgabe zugrunde eine Aufzuganlage mit reduziertem Schachtko fraum zu entwickeln, der möglichst einfach und effizient im Unterhalt ist. In this concept, however, the permanent damage to the cabin roof has a negative effect. Because once the demolition edge is broken, the canopy must be replaced. These repairs are relatively expensive and expensive. In addition, these works lead to a longer failure of the elevator system. Therefore, the present invention has the object to develop a lift system with reduced Schachtko fraum, which is as simple and efficient to maintain.
Gemäss eines ersten Aspekts umfasst die Aufzugsanlage eine Kabine und eine Kabinendecke, die zumindest über ein Kabinendeckenteil verfügt. Das Kabinen- deckenteil ist mittels mindestens eines Halteelements aufgehängt und deckt eine Öffnung der Kabinendecke ab. Die Aufzugsanlage zeichnet sich dadurch aus, dass das Halteelement eine magnetische Kraft auf das Kabinendeckenteil ausübt. Diese magnetische Kraft ist zumindest gleich gross wie die Gewichtskraft des Kabinendeckenteils. According to a first aspect, the elevator installation comprises a cabin and a cabin ceiling which has at least one cabin ceiling part. The cabin ceiling part is suspended by means of at least one retaining element and covers an opening of the cabin ceiling. The elevator system is characterized in that the holding element exerts a magnetic force on the cabin ceiling part. This magnetic force is at least equal to the weight of the cabin ceiling part.
Unter Gewichtskraft wird hier die Gravitationskraft m*g verstanden. Diese Gravitationskraft schließt auch alle Gewichtskräfte von Elementen ein, die am Kabinendeckenteil angeordnet sind und zumindest teilweise vom Halteelement mitgetragen werden. By gravitational force is meant the gravitational force m * g. This gravitational force also includes all weight forces of elements which are arranged on the cabin ceiling part and are at least partially carried by the holding element.
Zudem ist die vom Halteelement ausgeübte magnetische Kraft vorzugsweise dermaßen ausgelegt, dass sie zumindest gleich gross ist wie die Gewichtskraft sowie eine Betriebskraft, die auf das Kabinendeckenteil wirk. Unter einer Betriebskraft wird hier beispielsweise eine Beschleunigungskraft verstanden, die beim Beschleunigen oder Abbremsen der Kabine entsteht und die im Betrieb der Aufzugsanlage zusätzlich zur Gewichtskraft auf das Kabinendeckenteil wirkt. In addition, the magnetic force exerted by the holding element is preferably designed so that it is at least as large as the weight and an operating force acting on the cabin ceiling part. Under an operating force is understood here, for example, an acceleration force that arises during acceleration or deceleration of the cabin and the operation of the elevator system in addition to the weight on the cabin ceiling part acts.
Der Vorteil einer solchen Aufzugsanlage liegt in der einfachen Montage des Kabinendeckenteils über Halteelemente. Die Halteelemente sind dabei am Kabinendach angeordnet und halten mittels einer magnetischen Kraft das Kabinendeckenteil am Kabinendach. Das Kabinendeckenteil kann somit lediglich in einem Arbeitsschritt am Kabinendach befestigt werden, indem das Kabinendeckenteil zu den Halteelementen hochgehalten wird. The advantage of such a lift system lies in the simple installation of the cabin ceiling part on holding elements. The holding elements are arranged on the cabin roof and hold by means of a magnetic force the cabin ceiling part on the cab roof. The cabin ceiling part can thus be fixed only in one step on the car roof by the cabin ceiling part is held up to the holding elements.
In einem weiteren Aspekt bildet das Haltelement eine lösbare Verbindung zwischen der Kabinendecke und dem Kabinendeckenteil. Dabei löst sich die Verbindung ab einer vorgebbaren kritischen Auslösekraft, die von oberhalb der Ka- binendecke auf das Kabinendeckenteil wirkt. In a further aspect, the retaining element forms a releasable connection between the car ceiling and the cabin ceiling part. In this case, the connection is released from a predefinable critical release force, which is from above the Ka binendecke acts on the cabin ceiling part.
Besonders vorteilhaft ist die präzise und wählbare Einstellung der kritischen Auslösekraft, bis welcher das Kabinendeckenteil an der Kabinendecke festgehalten wird. Die Anzahl der Halteelemente ist frei wählbar und auf eine bestimmte kritische Auslösekraft, bei der die Verbindung auslöst einstellbar. Zusätzlich kann die kritische Auslösekraft mittels Halteelementen unterschiedlicher magnetischer Kraft variiert werden. Particularly advantageous is the precise and selectable setting of the critical release force, to which the cabin ceiling part is held on the cabin ceiling. The number of retaining elements is freely selectable and to a certain critical triggering force at which the connection triggers adjustable. In addition, the critical release force can be varied by means of holding elements of different magnetic force.
Die kritische Auslösekraft wird dermaßen eingestellt, dass bei Betreten des Ka- binendeckenteils die Verbindung zwischen Kabinendeckenteil und der Kabinendecke zuverlässig löst. Dies ist der Fall in einem Gewichtskraftbereich von ca. 100 bis 300 N. The critical release force is adjusted to such an extent that the connection between the cabin ceiling section and the cabin ceiling reliably releases when entering the cab ceiling section. This is the case in a weight range of about 100 to 300 N.
Ein weiterer Aspekt betrifft eine mehrteilige Ausführung des Kabinendecken- teils. Mit steigender Grundfläche des Kabinendeckenteils kann die Zuverlässigkeit beim Lösen der Verbindung zwischen dem Kabinendeckenteil und dem Kabinendach beeinträchtigt sein. Denn bei einer großen Grundfläche mit weit auseinander liegenden Halteelementen und einer lokal wirkenden Gewichtskraft einer auftretenden Person, werden die Halteelemente stark ungleichmässig belastet. Versuche haben gezeigt, dass Kabinendeckenteile ab einer Grundfläche von 2 m2 bevorzugt zweiteilig ausgelegt sind. Bei noch größeren Grundflächen ist das Kabinendeckenteil auch dreiteilig oder nach Bedarf aus noch mehr Teilstücken ausführbar. Another aspect relates to a multi-part design of the cabin ceiling part. With increasing footprint of the cabin ceiling portion, the reliability in releasing the connection between the cabin ceiling portion and the car roof may be impaired. Because with a large base with widely spaced holding elements and a locally acting weight of a person occurring, the holding elements are heavily loaded unevenly. Experiments have shown that cabin ceiling parts are preferably designed in two parts from a base of 2 m 2 . For even larger base areas, the cabin ceiling section can also be made in three parts or as needed from even more sections.
Eine mehrteilige Auslegung des Kabinendeckenteils hat den Vorteil, dass die Gewichtskraft einer darauf tretenden Person im wesentlichen gleichmäßig auf die Haltelemente verteilt wird und so bei überschreiten der kritischen Auslösekraft, alle Verbindung bei den Halteelementen zuverlässig gelöst werden. A multi-part design of the cabin ceiling part has the advantage that the weight of a person passing on it is distributed substantially uniformly on the holding elements and so when exceeding the critical release force, all connection in the holding elements are reliably solved.
Vorzugsweise ist das Halteelement als Magnetband oder als Magnetelement ausgestaltet. Preferably, the holding element is designed as a magnetic tape or as a magnetic element.
Bei der Verwendung von Magnetbändern sind mindestens zwei Magnetbänder auf gegenüberliegenden Seiten des Kabinendeckenteils am Kabinendach montiert. Es ist auch möglich vier Magnetbänder auf allen vier Seiten des Kabinendeckenteils am Kabinendach anzuordnen. When using magnetic tapes are at least two magnetic tapes mounted on opposite sides of the cab ceiling part on the cab roof. It is also possible to arrange four magnetic tapes on all four sides of the cabin ceiling part on the cab roof.
Die Magnetelemente sind typischerweise handelsübliche zylindrische Elemente, quadratische oder rechteckige Elemente. Je nach Größe und Magnetstärke der Magnetelemente sind mehrere dieser Magnetelemente entlang den Seitenrändern des Kabinendeckenteils am Kabinendach angeordnet. Dabei sind die Magnetelemente bevorzugterweise äquidistant beabstandet. The magnetic elements are typically commercially available cylindrical elements, square or rectangular elements. Depending on the size and magnetic strength of the magnetic elements, a plurality of these magnetic elements are arranged along the side edges of the cabin ceiling part on the cabin roof. The magnetic elements are preferably equidistantly spaced.
In einem weiteren Aspekt ist ein Halteelement mittels eines Stellelements höhenverstellbar am Kabinendach angeordnet. Das Stellelement ist vorzugsweise als Stellschraube ausgestaltet. Das Halteelement ist dabei mittels des Stellelements am Kabinendach aufgehängt. So kann die Höhe des Halteelements gegenüber dem Kabinendach reguliert werden. Als Stellelement sind neben Stellschrauben auch Stifte, die über einen Raster oder Klemmechanismus auf unterschiedlicher Höhe am Kabinendach feststellbar sind, verwendbar. In a further aspect, a holding element is arranged by means of an adjusting element height adjustable on the cabin roof. The adjusting element is preferably designed as a set screw. The holding element is suspended by means of the adjusting element on the cab roof. Thus, the height of the retaining element relative to the cab roof can be regulated. As an adjusting element in addition to screws and pins that can be determined via a grid or clamping mechanism at different heights on the cabin roof, usable.
Der Vorteil der Höheneinstellung der Halteelemente liegt darin, die Halteelemente so einzustellen, dass sie möglichst ohne Verkantung eine ideale Kontaktfläche mit dem Kabinendeckenteil bilden. Somit ist eine definierte Wirkung einer magnetischen Kraft eines Halteelements auf das Kabinendeckenteil gewährleistet. The advantage of the height adjustment of the holding elements is to adjust the holding elements so that they form an ideal contact surface with the cabin ceiling part as possible without tilting. Thus, a defined effect of a magnetic force of a holding element is ensured on the cabin ceiling part.
Ein weiterer Aspekt betrifft ein Sicherheitselement, welches das Kabinendeckenteil mit dem Kabinendach verbindet. Das Sicherheitselement hält das Kabinendeckenteil nach Lösen der Verbindung auf einer vorgebbaren Mindesthöhe gegenüber dem Kabineninnenraum. Vorzugsweise ist das Sicherheitselement als Gurt, Seil, Kabel oder dergleichen ausgestaltet. Another aspect relates to a security element which connects the cabin ceiling part with the car roof. The security element keeps the cabin ceiling part after releasing the connection to a predetermined minimum height relative to the cabin interior. Preferably, the security element is designed as a belt, rope, cable or the like.
Optional sind auch zwei oder mehr Sicherheitselemente einsetzbar. Insbesondere bei einer mehrteiligen Ausführung des Kabinendeckenteils ist jedes einzelne Teil mit zumindest einem Sicherheitselement gesichert. In einer weiteren bevorzugten Ausführung ist das Kabinendeckenteil bzw. jedes einzelne Teil mit zwei oder mehreren Sicherheitselementen gesichert. Optionally, two or more security elements can be used. In particular, in a multi-part design of the cabin ceiling part of each individual part is secured with at least one security element. In a further preferred embodiment, the cabin ceiling part or each individual part with two or multiple security items.
Vorteilig wirkt sich dabei aus, dass das Kabinendeckenteil nicht unkontrolliert in den Innenraum der Kabine stürzt. Dies verhindert mögliche Verletzungen einer Person, die das Kabinendeckenteil eindrückt, und der Kabineninsassen. An advantage of this is that the cabin ceiling part does not crash uncontrollably into the interior of the cabin. This prevents possible injury to a person pushing in the cabin ceiling part and the cabin occupant.
Deweiteren ist optional ein Fangnetz dermassen auf der Kabinendecke angeordnet, dass mittels diesem eine Person, die auf das Kabinendeckenteil tritt, auffangbar ist und an einem Sturz in die Kabine hinderbar ist. Deweiteren is optionally a safety net arranged on the cabin ceiling so that by means of this a person who steps on the cabin ceiling part, is trappable and hinderable in a fall into the cabin.
Im Folgenden wird die Erfindung durch Ausführungsbeispiele und anhand von Zeichnungen verdeutlicht und weiter beschrieben. Es zeigt: In the following the invention is illustrated by exemplary embodiments and with reference to drawings and described further. It shows:

Fig. 3 Eine Detailansicht einer Aufhängung des Halteelements mit Stellschraube zur Höheneinstellung des Halteelements. Fig. 3 is a detail view of a suspension of the retaining element with adjusting screw for height adjustment of the retaining element.
Die Figuren l a und lb zeigen eine Aufzugsanlage 10 mit einer Kabine 1. Die Kabine 1 ist in einem Schacht 6 entlang von Führungsschienen verfahrbar. Dazu verfügt die Aufzugsanlage typischerweise über ein Gegengewicht, ein Trag- und Treibmittel, an dem die Kabine 1 und das Gegengewicht aufgehängt sind und über eine Antriebseinheit, die über eine Treibscheibe in Wirkkontakt mit dem Trag- und Treibmittel steht. Aus Übersichtlichkeitsgründen sind Führungsschie- nen, Gegengewicht, Trag- und Treibmittel sowie die Antriebseinheit in den Figuren l a und lb nicht dargestellt. FIGS. 1 a and 1 b show an elevator installation 10 with a car 1. The car 1 can be moved in a shaft 6 along guide rails. For this purpose, the elevator system typically has a counterweight, a support and propellant, on which the car 1 and the counterweight are suspended, and a drive unit, which is in operative contact with the carrying and propellant via a traction sheave. For reasons of clarity, guide rails NEN, counterweight, carrying and blowing agent and the drive unit in the figures la and lb not shown.
Die Kabine 1 ist gegen oben hin mit einer Kabinendecke 2 begrenzt. Die Kabinendecke 2 verfügt über einen Bereich, der nachgiebig ausgestaltet ist. Dazu ist eine Öffnung in der Kabinendecke 2 vorgesehen, die durch ein Kabinendeckent- eil 3 abdeckbar ist. Vorteilhafterweise ist die Grundfläche des Kabinendecken- teils 3 grösser als die Grundfläche der Öffnung im Kabinendach 2. Dementsprechend besteht ein Überlappungsbereich im Randbereich des Kabinendeckenteils 3 mit dem die Öffnung begrenzenden Bereich der Kabinendecke 2. Dabei ist das Kabinendeckenteil 3 unterhalb der Kabinendecke 2 angeordnet. Damit ist sichergestellt, dass beim Betreten des Kabinendeckenteils 3 selbiges in den Innenraum der Kabine 1 abgesenkt wird und der verfügbare Sicherheitsraum bezüglich des oberen Schachtendes vergrössert ist. The cabin 1 is limited towards the top with a cabin ceiling 2. The cabin ceiling 2 has an area that is designed compliant. For this purpose, an opening in the cabin ceiling 2 is provided, which can be covered by a Kabinendeckent- part 3. The base area of the cabin ceiling part 3 is advantageously larger than the base area of the opening in the cabin roof 2. Accordingly, there is an overlapping area in the edge region of the cabin ceiling part 3 with the region of the cabin ceiling 2 delimiting the opening. The cabin ceiling part 3 is arranged below the cabin ceiling 2. This ensures that when entering the cabin ceiling part 3 selbiges is lowered into the interior of the cabin 1 and the available security space is increased with respect to the upper shaft end.
Das Kabinendeckenteil 3 ist im gezeigten Ausführungsbeispiel mittels acht Halteelemente 4, je zwei pro Seite des Kabinendeckenteils 3, an der Kabinendecke 2 festgehalten. Die Halteelemente 4 sind im Überlappungsbereich zum Kabinendeckenteil 3 an der Kabinendecke 2 aufgehängt. The cabin ceiling part 3 is held in the illustrated embodiment by eight retaining elements 4, two per side of the cabin ceiling part 3, on the cabin ceiling 2. The holding elements 4 are suspended in the overlapping area to the cabin ceiling part 3 on the cabin ceiling 2.
Die Halteelemente 4 sind als Elemente gestaltet, die eine magnetische Kraft auf das Kabinendeckenteil ausüben. Dazu eignen sich insbesondere handelsübliche zylindrische oder rechteckig ausgestaltete Magnetelemente. Alternativ dazu sind auch Magnetbänder einsetzbar. Die Anzahl der eingesetzten Magnetelemente und die Magnetkraft eines einzelnen Magnetelements ist bezüglich der Seitenlängen des Kabinendeckenteils 3 und der Gewichtskraft des Kabinendeckenteils 3 und der darauf wirkenden Betriebskräfte auszulegen. The holding elements 4 are designed as elements which exert a magnetic force on the cabin ceiling part. Commercially available cylindrical or rectangular magnet elements are particularly suitable for this purpose. Alternatively, magnetic tapes can be used. The number of magnetic elements used and the magnetic force of a single magnetic element with respect to the side lengths of the cabin ceiling portion 3 and the weight of the cabin ceiling portion 3 and the operating forces acting thereon interpreted.
Die Gesamtkraft der Magnetkräfte aller Halteelemente 4, die das Kabinendeckenteil 3 an der Kabinendecke 2 festhält, ist so zu bemessen, dass diese Gesamtkraft mindestens so gross wie die Gewichtskraft des Kabinendeckenteils 3. In einer besonders bevorzugten Ausführung ist die Gesamtkraft mindestens so gross wie die Gewichtskraft und die auf das Kabinendeckenteil 3 wirkenden Betriebskräfte. Damit ist gewährleistet, dass das Kabinendeckenteil 3 im Betrieb der Aufzuganlage zuverlässig an der Kabinendecke 2 angeordnet bleibt. Zudem soll die Gesamtkraft aller Magnetkräfte eine kritische Auslösekraft von 300 N nicht überschreiten, damit sich die Verbindungen der Halteelemente 4 beim Betreten des Kabinendeckenteils 3 lösen und das Kabinendeckenteil 3 in den Innenraum der Kabine 1 fällt. The total force of the magnetic forces of all retaining elements 4, which holds the cabin ceiling part 3 to the cabin ceiling 2, is to be such that this total force at least as large as the weight of the cabin ceiling part 3. In a particularly preferred embodiment, the total force is at least as large as the weight and the operating forces acting on the cabin ceiling part 3. This ensures that the cabin ceiling part 3 in operation the elevator system remains reliably arranged on the cabin ceiling 2. In addition, the total force of all magnetic forces should not exceed a critical tripping force of 300 N, so that the connections of the holding elements 4 solve upon entering the cabin ceiling part 3 and the cabin ceiling part 3 falls into the interior of the cabin 1.
Im gezeigten Ausführungsbeispiel der Figuren l a und lb sind auf jeder Seite zwei Halteelemente 4 vorgesehen, um das Kabinendeckenteil 3 an der Kabinendecke zu halten. Davon Abweichend ist auch eine grössere oder kleinere Anzahl Halteelemente 4 auf jeder Seite des Kabinendeckenteils 3 einsetzbar. In the illustrated embodiment of Figures l a and lb two retaining elements 4 are provided on each side to hold the cabin ceiling part 3 to the cabin ceiling. Deviating from this, a larger or smaller number of retaining elements 4 can be used on each side of the cabin ceiling part 3.
Bei Halteelementen 4, die als Magnetband ausgelegt sind, ist vorzugsweise ein Halteelement 4 pro Seite einsetzbar. Dabei ist das Magnetband typischerweise in etwa gleich lang wie eine Seitenlänge des Kabinendeckenteils 3. For holding elements 4, which are designed as magnetic tape, a holding element 4 per side is preferably used. In this case, the magnetic tape is typically approximately the same length as a side length of the cabin ceiling part 3.
Die Figuren 2a und 2b zeigen ein weiteres Ausführungsbeispiel der Aufzugsanlage 20 mit einer Kabine 1 1 , die in einem Schacht 16 verfahrbar ist. Im Unterschied zum Ausführungsbeispiel der Figuren l a und lb verfügt die Aufzugsanlage 20 hier über ein Sicherheitselement 15. Vorzugsweise ist das Sicherheitselement 15 als Seil, Kabel, Gurt oder dergleichen ausgeführt. Figures 2a and 2b show another embodiment of the elevator installation 20 with a car 1 1, which is movable in a shaft 16. In contrast to the exemplary embodiment of FIGS. 1a and 1b, the elevator installation 20 here has a security element 15. The security element 15 is preferably designed as a cable, cable, belt or the like.
Im hier gezeigten Ausführungsbeispiel ist das Sicherheitselement 15 als Gurt ausgelegt. Gemäss Figur 2b sind zwei solche Sicherheitselemente 15 vorgesehen, die beabstandet, im Wesentlichen parallel zueinander verlaufend, angeordnet sind. Dabei sind die Enden der Gurte 15 je an gegenüberliegenden Seiten der Öffnung an der Kabinendecke 12 befestigt. Das Kabinendeckenteil 13.1 ist jeweils in einer Schlaufe der Gurte 15 aufgehängt. Der konkret gewählte Verlauf der Gurte 15 im Bezug auf das Kabinendeckenteil 13.1 kann von der parallelen Anordnung abweichen. Ein schräger Verlauf der Gurte 15 zueinander mit oder ohne Üb er kreuzen ist ebenso möglich. In the embodiment shown here, the security element 15 is designed as a belt. According to FIG. 2 b, two such security elements 15 are provided, which are arranged at a distance from one another and essentially parallel to one another. The ends of the straps 15 are each attached to opposite sides of the opening on the cabin ceiling 12. The cabin ceiling part 13.1 is suspended in each case in a loop of the straps 15. The specifically selected course of the straps 15 with respect to the cabin ceiling part 13.1 may differ from the parallel arrangement. An oblique course of the straps 15 to each other with or without cross over he is also possible.
Alternativ zur Aufhängung des Kabinendeckenteils 13.1 in einer Schlaufe eines Sicherheitselements 15 ist das Kabinendeckenteil 13.1 auch an einem Ende eines Sicherheitselements 15 aufhängbar. Bei einer solchen Ausführung sind die vier Ecken des Kabinendeckenteils 13.1 je an einem ersten Ende eines Sicherheitselements 15 aufgehängt. Das zweite Ende der jeweiligen Sicherheitselemente 15 ist am Kabinendach 12 befestigt. As an alternative to the suspension of the cabin ceiling part 13.1 in a loop of a security element 15, the cabin ceiling part 13.1 can also be suspended at one end of a security element 15. In such an embodiment, the four Corners of the cabin ceiling part 13.1 each suspended at a first end of a security element 15. The second end of the respective security elements 15 is attached to the canopy 12.
Das Sicherheitselement 15 hält das Kabinendeckenteil 13 auch nach dem Lösen der Verbindungen der Halteelemente 14 bezüglich des Innenraums der Kabine 1 1 auf einer vorgebbaren Höhe. So wird sichergestellt, dass das Kabinendeckenteil 13.1 nicht auf sich bereits in der Kabine 1 1 aufhaltende Fahrgäste stürzt und möglicherweise verletzt. The security element 15 holds the cabin ceiling part 13 even after the release of the connections of the holding elements 14 with respect to the interior of the cabin 1 1 at a predetermined height. This ensures that the cabin ceiling portion 13.1 does not crash on passengers already in the car 1 1 and possibly injured.
In einer Ruheposition des Kabinendeckenteils 13. 1 , d.h. wenn das Kabinendeckenteil 13.1 von den Halteelementen 14 an der Kabinendecke 12 festgehalten ist, ist ein Sicherheitselement 15 in einem unbelasteten Zustand. Dementsprechend liegt ein Teil des Sicherheitselements 15 als eine Schlaufe auf dem Kabinendeckenteil 13.1 auf. Im Betrieb der Aufzugsanlage 20 können Vibrationen auftreten, die auf diese Schlaufen übertragen werden. Dies kann zu einer zusätzlichen Betriebskraft führen, die auf das Kabinendeckenteil 13.1 wirkt. Dies ist insofern nachteilig, dass diese zusätzliche Krafteinwirkung zu einem spontanen ungewollten Lösen der Verbindungen an den Halteelementen 14 führen kann. In a rest position of the cabin ceiling part 13. 1, i. when the cabin ceiling part 13.1 is held by the holding elements 14 on the car ceiling 12, a security element 15 is in an unloaded state. Accordingly, a part of the security element 15 rests as a loop on the cabin ceiling part 13.1. During operation of the elevator installation 20, vibrations may occur which are transmitted to these loops. This can lead to an additional operating force acting on the cab ceiling part 13.1. This is disadvantageous in that this additional force can lead to a spontaneous unwanted release of the compounds on the holding elements 14.
Dieser negative Effekt ist dadurch vermeidbar, dass eine frei aufliegende Schlaufe mittels eines Splints 18 oder eines anderen geeigneten Befestigungselements am Kabinendeckenteil 13.1 festgehalten ist. Alternativ dazu ist diese Schlinge auch auf dem Kabinendach 12 befestigbar. Dieser Splint 18 ist dermas- sen am Kabinendeckteil 13.1 bzw. Kabinendach 12 befestigt, dass nach einem Lösen der Verbindungen an den Halteelementen 14, ein jeweiliger Splint 1 8 beim Herunterfallen des Kabinendeckenteils 13. 1 in den Innenraum der Kabine 1 1 aus seiner Befestigung gezogen wird und somit das Sicherheitselement 15 frei gibt. This negative effect can be avoided by holding a freely resting loop on the cabin ceiling part 13.1 by means of a cotter pin 18 or another suitable fastening element. Alternatively, this loop is also fastened to the cabin roof 12. This split pin 18 is dermas- attached to the cabin roof part 13.1 or canopy 12, that after loosening the connections to the support members 14, a respective cotter pin 1 8 pulled down the cabin ceiling portion 13 1 in the interior of the cabin 1 1 from its attachment and thus the security element 15 is free.
Gemäss Figur 2a ist die Schlinge des Sicherheitselements 15, an der das Kabinendeckenteil 13.1 hängt durch eine Blinddecke 13.2 von unten abdeckbar. Damit ist das Sicherheitselement 15 aus dem Innenraum der Kabine 1 1 nicht einsehbar und ein schönes Erscheinungsbild sichergestellt. Zudem sichert die Blinddecke 13.2 die Gurte 15 vor Vandalismus. Die Blinddecke 13.2 ist vorzugsweise mittels Schraubverbindungen 17 oder weiterer geeigneter Befestigungselemente am Kabinendeckenteil 13.1 befestigt. According to FIG. 2a, the loop of the security element 15, on which the cabin ceiling part 13.1 hangs, can be covered by a blind cover 13.2 from below. Thus, the security element 15 from the interior of the cabin 1 1 is not visible and ensures a beautiful appearance. In addition, secures the Blind cover 13.2 the straps 15 against vandalism. The blind cover 13.2 is preferably fastened by means of screw 17 or other suitable fasteners on the cabin ceiling part 13.1.
Figur 3 zeigt eine Detailansicht einer Aufhängung eines Halteelements 4 an der Kabinendecke 2. In dieser Ausführungsvariante ist das Halteelement 4 mittels einer Stellschraube 8 und einer Stellmutter 7 höhenverstellbar gegenüber der Kabinendecke 2 angeordnet. Eine Aussparung in der Kabinendecke 2 dient der Stellmutter 7 als Lager, auf das die Stellmutter aufliegt. Die Stellschraube 8 ist einerseits mit dem Halteelement 4 verbunden und andererseits über ein Gewinde der Stellmutter 7 mit derselben verschraubt. Die relative Höhe des Halteelements 4 bzw. des daran aufgehängten Kabinendeckenteils 3 zur Kabinendecke 2 ist durch Drehen der Stellmutter 7 und der dadurch erzwungenen vertikalen Verschiebung der Stellschraube 8 justierbar. FIG. 3 shows a detailed view of a suspension of a retaining element 4 on the cabin ceiling 2. In this embodiment variant, the retaining element 4 is arranged adjustable in height relative to the cabin ceiling 2 by means of an adjusting screw 8 and an adjusting nut 7. A recess in the cabin ceiling 2 serves the adjusting nut 7 as a bearing on which the adjusting nut rests. The adjusting screw 8 is on the one hand connected to the holding element 4 and on the other hand screwed via a thread of the adjusting nut 7 with the same. The relative height of the retaining element 4 and the cabin ceiling part 3 suspended therefrom to the cabin ceiling 2 can be adjusted by turning the adjusting nut 7 and thereby enforcing vertical displacement of the adjusting screw 8.
Die Aufhängung gemäss Figur 3 ist in beiden Ausführungsbeispielen der Figuren l a, lb und Figuren 2a, 2b einsetzbar. The suspension according to FIG. 3 can be used in both exemplary embodiments of FIGS. 1a, 1b and FIGS. 2a, 2b.
Optional zu den Ausführungsbeispielen in den Figuren 1 , 2a und 2b ist auf der Oberseite der Kabinendecke 2, 12 ein Fangnetz anordenbar. Vorzugsweise deckt das Fangnetz im Wesentlichen mindestens das Kabinendeckenteil 3, 13.1 ab. Das Fangnetz ist dabei an seinen Extremitäten dermassen an der Kabine 1 , 1 1 bzw. Kabinendecke 2, 12 befestigt, dass das Fangnetz eine Person, die das Kabinendeckenteil 3, 13.1 betritt, trotz nachgebendem Kabinendeckteil 3, 13.1 nicht in das Innere der Kabine 2, 12 stürzt. Dazu ist die Maschenweite des Fangnetzes vorzugsweise so fein gewählt, dass zumindest ein Fuss am Durchtreten durch eine Masche gehindert ist. Aus Gründen der Übersichtlichkeit ist das Fangnetz in den Figuren 1 , 2a und 2b nicht dargestellt. Optionally to the embodiments in Figures 1, 2a and 2b, a safety net can be arranged on the top of the cabin ceiling 2, 12. Preferably, the safety net substantially covers at least the cabin ceiling part 3, 13.1. The safety net is attached at its extremities to the car 1, 1 1 or cabin ceiling 2, 12, that the safety net a person who enters the cabin ceiling part 3, 13.1, despite yielding cabin ceiling part 3, 13.1 not in the interior of the cabin. 2 12 crashes. For this purpose, the mesh size of the safety net is preferably chosen so fine that at least one foot is prevented from passing through a mesh. For reasons of clarity, the safety net is not shown in FIGS. 1, 2a and 2b.
