Definitions
- the present invention relates to an elevator car for an elevator system and an elevator system equipped with such an elevator car.
- Elevator cabins are used in elevator systems in order to generally be able to convey people or objects vertically.
- the elevator car can be moved up and down within an elevator shaft using a drive.
- a balustrade can be provided, which is permanently installed on the roof of the elevator car and, for example, protrudes all around the roof above it at a sufficient height so that people standing on the roof cannot fall over the balustrade.
- the provision of such a balustrade entails additional material and assembly costs and / or the balustrade may have to comply with certain safety regulations, for example, in order to ensure, for example, that a person cannot be pinched between the balustrade and a ceiling of the elevator shaft.
- a so-called clearance limiter for an elevator car is proposed, in which a generic comparable elevator car is disclosed which has a fall protection arrangement projecting over an edge of the roof for protecting people from falling into the elevator shaft.
- a space limiter permanently projects from the side of the elevator car and largely closes a space or gap between the elevator car and, for example, a side wall of the elevator shaft, so that persons on the roof of the elevator car cannot slide through this space or gap and fall.
- an elevator car in which suitable safety measures reliably prevent people on a roof of the elevator car from falling.
- the safety measures are implemented in a structurally simple manner, can be implemented inexpensively and / or hinder a method of the elevator car within the elevator shaft as minimally as possible.
- an elevator car for an elevator installation which has a floor, a roof and a plurality of side walls.
- the side walls define an outer contour of the elevator car in a top view of the elevator car.
- the elevator car furthermore has a plurality of elongated securing struts which project outwards from the roof of the elevator car with their longitudinal direction transverse to an edge of the roof beyond the outer contour of the elevator car.
- the securing struts are arranged at such intervals on the roof that the person to be protected can not fall through between two adjacent securing struts.
- a second aspect of the invention relates to an elevator installation which has an elevator shaft and an elevator car according to an embodiment of the aforementioned first aspect of the invention.
- the securing struts are arranged on the elevator car in such a way that both a spacing between adjacent securing struts and a distance between a securing strut on the one hand and a wall of the elevator shaft or an elevator shaft component attached to the wall on the other hand is less than 30 cm for all securing struts.
- a laterally protruding clearance limiter can be found in the EP 1 849 732 A1 Although the configuration shown largely closes a gap between the elevator car and, for example, an elevator shaft wall, this can also entail, for example, that an air resistance which the elevator car experiences through the elevator shaft during rapid travel is increased considerably and thus possibly an increased drive power for the Procedure of the elevator car must be provided.
- the securing struts protrude into the gap between the elevator car and, for example, the elevator shaft wall, the securing struts being designed and spaced apart from one another such that the remaining spaces between adjacent securing struts or between a securing strut and a wall of the elevator shaft or a component of the elevator system statically attached to this wall is small enough , so that a person can no longer slip through and then crash.
- a geometry and / or configuration of the elongated securing struts can be selected appropriately so that it can withstand mechanical loads such as occur when a person steps or falls on the securing strut, for example, without deforming beyond a safety-relevant dimension.
- the stability of the securing strut should be selected such that it does not deform so much under such a load that the distances between a securing strut and an adjacent securing strut or a wall of the elevator shaft are increased by a permissible dimension of, for example, 30 cm.
- the securing struts are structurally designed such that a width of a securing strut, measured perpendicular to its longitudinal direction and parallel to the direction of extension of the roof, is smaller than twice a height of the securing strut, measured perpendicular to its longitudinal direction and perpendicular to the plane of extent of the roof.
- an aspect ratio of the securing struts should be as small as possible than 2: 1.
- Such an aspect ratio can preferably even be equal to or less than 1: 1, that is to say a width of the securing strut is less than its height.
- the aspect ratio can also be selected to be equal to or less than 1: 2, that is to say the width of the securing strut is less than half the height.
- the securing strut should not only be elongated, that is to say have a greater extent in its direction of longitudinal extension than in both directions orthogonal thereto, but also be relatively narrow, that is to say preferably have a width which is less than twice or even simpler than that Height of the securing strut.
- Such securing struts can be mechanically stable and at the same time also have a low weight.
- Such safety struts acting as free space limiters can protrude outward beyond the outer contour of the elevator car and thereby prevent a person from slipping through the gap between the elevator car and the elevator shaft wall, without, however, filling this gap essentially over the entire area.
- An overall outer contour of the elevator car that is to say a contour defined by the side walls plus a contour which is supplemented by the laterally protruding securing struts, is not enlarged over a large area, but rather the securing struts only protrude linearly locally into the gap. Since the overall outer contour can remain smaller than, for example, in the case of the conventional free space limiters mentioned above, an air resistance of the elevator car can be kept relatively low when moving through the elevator shaft.
- the securing struts have a width of less than 10 cm, preferably less than 5 cm or 3 cm. Furthermore, according to one embodiment, the securing struts can have a height of more than 2 cm, preferably more than 5 cm. Safety struts with such dimensions promise adequate mechanical stability with low use of materials, low weight and little contribution to air resistance in the elevator car.
- the securing struts with a length of at least 5 cm, preferably at least 10 cm or more preferably at least 20 cm, project outward beyond the outer contour of the elevator car.
- the securing struts locally block a free space or gap adjacent to the elevator car.
- a total length of the securing struts can be significantly longer than the part projecting outwards, since some of the securing struts are located on and on the roof of the elevator car and can be fastened there.
- a lateral distance between adjacent securing struts is greater than a width of the securing struts.
- a plurality of securing struts can be provided on the roof of the elevator car, each of which is elongated and protrudes beyond the contour of the roof or the elevator car, the securing struts in a lateral direction, that is, in a direction parallel to an edge of the roof are spaced apart, preferably at regular intervals, and a distance between adjacent securing struts is greater than a width of an individual securing strut. So far apart from each other laterally Safety struts can contribute to a reduction in the weight of the elevator car and / or a reduction in the air resistance caused by the safety struts.
- the securing struts are arranged along edges of the roof at intervals of less than 30 cm from one another. Such a small spacing between adjacent securing struts may be necessary to prevent a person from slipping between two adjacent securing struts.
- the securing struts are designed as elongated metal profiles, at least in an area that projects beyond the edge of the roof.
- they can be designed as elongated hollow metal profiles.
- Such profiles can be designed with the aspect ratio mentioned above.
- Metal profiles or metal hollow profiles can enable a very high mechanical strength with a low weight.
- a wide variety of metals, for example steel, can be used as materials.
- the securing struts can also be provided from other materials and / or with a different structural or geometric design.
- securing struts can be formed from plastics, in particular fiber-reinforced plastics that can withstand high mechanical loads. Composite materials can also be used.
- the securing struts can be arranged essentially flush with an upward-facing surface of the roof.
- flush can mean that an upward-facing surface of a securing strut extends approximately in the same plane as the upward-facing surface of the roof.
- Essentially flush can be interpreted in such a way that the extension plane of the upward-facing surface of the securing strut differs at most so slightly from the extension plane of the upward-facing surface of the roof in a vertical direction that between the surface of the roof and the surface of the Securing strut neither a significant paragraph up nor a significant paragraph down occurs.
- a maximum generated paragraph that is, a maximum permissible deviation from an ideal level
- this can prevent the safety strut from becoming a "trip hazard" for people on the roof.
- the securing struts are straight along their longitudinal direction.
- the securing struts can be provided as linear components, for example as straight rods or tubes. Such struts can be easily manufactured and assembled.
- the securing struts can be curved or kinked along their longitudinal direction.
- the securing strut is elongated, i.e. is longer than wide, but not straight over its entire length, but at least in some areas with curvatures or kinks.
- such a curvature or kink (for example in the form of a bend) can be designed such that a securing strut initially extends from the roof of the elevator car perpendicularly to its edge, but then has a curvature or kink so that it is further out lying areas of the securing strut can extend obliquely or even parallel to the edge of the roof.
- the free spaces or gaps prevailing there can also be adequately blocked between the outer contour of the elevator car and surrounding stationary structures of the elevator shaft.
- the securing struts can be attached to the roof or to one of the side walls or both to the roof and to one of the side walls.
- a securing strut can only be attached to the roof.
- the securing strut can only be attached to one of the side walls.
- the securing strut can be attached both to the roof and to one of the side walls.
- the securing strut can simply be mounted on the roof if it is only attached. If only attached to one of the side walls, the safety strut can be flush with the roof. A combination of attachment on the roof and attachment to a side wall can allow a good compromise between simple attachment, good flush and possibly high mechanical stability.
- the securing strut can, for example, be firmly connected to the roof and / or the side wall and / or can only be supported on pressure in partial areas.
- At least one elevator shaft component which is vertically extending through the elevator shaft and / or is stationary in the elevator shaft is arranged in the elevator shaft.
- the securing struts are arranged on the elevator car in areas laterally next to the elevator shaft component.
- stationary guide rails can be provided in the elevator shaft, for example, or movable support means, such as ropes or belts, extending vertically through the elevator shaft.
- movable support means such as ropes or belts, extending vertically through the elevator shaft.
- These elevator shaft components should of course not collide with the securing struts provided on the elevator cabin and projecting beyond their outer contour when the elevator car is being moved within the elevator shaft.
- free spaces between the elevator car and the elevator shaft wall or the elevator shaft components should be sufficiently blocked by the securing struts.
- the securing struts can be provided with a foam or another protective material at least in the gap in the section or at least in the area of the free end.
- Fig. 1 shows an elevator car 1, which can be moved in the vertical direction with the aid of a rope-like or belt-like suspension element 3 within an elevator shaft 5 of an elevator installation 7.
- the elevator car 1 has a floor 9, a roof 11 and a plurality of side walls 13.
- the elevator car 1 also has an elevator door 15 on a side facing a floor 17.
- a free space 23 between the side wall 13 of the elevator car 1 there and a wall 19 of the elevator shaft 5.
- elevator shaft components and / or a counterweight and / or other components can be stationary or to be moved (in Fig. 1 not shown).
- the free space 23 can have dimensions of more than 30 cm, for example, so that a person located on the roof 11 of the elevator car 1 could slide through the free space 23 between the elevator car 1 and the wall 19 of the elevator shaft 5 and fall.
- a plurality of elongated side struts 21 are provided on the elevator car 1, which extend in an approximately horizontal direction and protrude outwards beyond an outer contour of the elevator car 1 formed by the side walls 13 to the walls 19 of the elevator shaft 5.
- Fig. 2 shows a perspective view of a partial area of the elevator car 1.
- Fig. 3 shows a top view of the roof 11 of an elevator car 1 within an elevator shaft 5.
- Several elongated securing struts 21 are arranged in the area of the roof 11 and project laterally beyond the side walls 13.
- the securing struts 21 are laterally spaced apart, that is to say in a direction parallel to an edge 25 of the roof 11.
- a lateral distance D between adjacent securing struts 21 is significantly larger than a width b of the individual securing struts 21.
- the lateral distance D between adjacent securing struts 21 is less than 30 cm.
- the elongated securing struts 21 are arranged and designed in this way on the elevator car 1 and protrude into the free space 23 with a length 1 such that, in addition to the distance D between adjacent securing struts 21, there is also a distance between the securing struts 21 and an adjacent wall 19 of the Elevator shaft 5 or an elevator shaft component 27, 29, 31 attached to this wall 19 is smaller than 30 cm.
- the elevator shaft components can, for example, be guide rails 29 and their holders 27 or be formed by subregions 31 of the suspension means 3.
- security struts 22 which are bent can also be provided.
- Such kinked safety struts 22 can serve, in particular near a corner 33 of the contour of the elevator car 1, to protrude locally into existing parts of the free space 23 and to be able to block it in a fall-preventing manner.
- Fig. 4 shows a simple embodiment of a securing strut 21 and its attachment to the roof 11 of an elevator car 1.
- the securing strut 21 is designed as a rod-shaped metal profile with a rectangular, in particular square, cross-section.
- the securing strut 21 rests with a partial area 37 on the roof 11 and is fastened thereon with a fastening means 35 such as, for example, a screw, a rivet or the like.
- a plurality of fastening means 35 can also be provided in order to be able to fasten the securing strut so that it cannot rotate.
- a further partial area 39 of the securing strut 21 projects transversely, preferably vertically, beyond the edge 25 of the roof 11 and thus into the free space 23.
- the securing strut 21 is structurally designed such that its width b is at most twice as large as its height h.

- a surface 45 of the securing strut 21 is approximately flush with a surface 47 of the roof 11. Nevertheless, the securing strut 21 can withstand high mechanical loads since it is additionally supported laterally on the side wall 13 of the elevator car 1.
- the securing struts 21 can additionally have a foam layer (not shown) or another protective material.
- the foam layer can completely encase the securing struts 21 or can only be attached to the upper surface of the securing strut 21. Thanks to the foam layer, people can be further protected against injuries.

Die vorliegende Erfindung betrifft eine Aufzugkabine für eine Aufzuganlage sowie eine mit einer solchen Aufzugkabine ausgestattete Aufzuganlage.The present invention relates to an elevator car for an elevator system and an elevator system equipped with such an elevator car.
In Aufzuganlagen werden Aufzugkabinen eingesetzt, um Personen oder Gegenstände im Allgemeinen vertikal befördern zu können. Die Aufzugkabine kann dabei innerhalb eines Aufzugschachts mithilfe eines Antriebs auf- und ab bewegt werden.Elevator cabins are used in elevator systems in order to generally be able to convey people or objects vertically. The elevator car can be moved up and down within an elevator shaft using a drive.
Beispielsweise während einer Wartung oder auch im Rahmen einer Evakuierung von Personen aus der Aufzugkabine kann es vorgesehen sein, dass Personen auf ein Dach der Aufzugkabine gelangen bzw. sich dort aufhalten. Beispielsweise kann vorgesehen sein, dass Wartungspersonal das Dach der Aufzugkabine nutzt, um auf diesem stehend Wartungs- oder Reparaturarbeiten innerhalb des Aufzugschachts durchführen zu können.For example, during maintenance or as part of an evacuation of people from the elevator car, it can be provided that people get to or stay on a roof of the elevator car. For example, it can be provided that maintenance personnel use the roof of the elevator car in order to be able to carry out maintenance or repair work standing inside the elevator shaft.
Für Aufzuganlagen geltende Sicherheitsvorschriften regeln, dass auf dem Dach der Aufzugkabine befindliche Personen gegen ein versehentliches Abstürzen von der Aufzugkabine in den Aufzugschacht gesichert werden müssen.Safety regulations applicable to elevator systems regulate that persons on the roof of the elevator car must be secured against accidental falling from the elevator car into the elevator shaft.
Hierzu kann beispielsweise eine Balustrade vorgesehen werden, die auf dem Dach der Aufzugkabine fest installiert ist und beispielsweise umlaufend um das Dach über dieses nach oben in einer ausreichenden Höhe übersteht, so dass auf dem Dach stehende Personen nicht über die Balustrade fallen können. Allerdings bringt das Vorsehen einer solchen Balustrade zusätzlichen Material- und Montageaufwand mit sich und/oder die Balustrade muss gegebenenfalls ihrerseits bestimmten Sicherheitsvorschriften entsprechen, um beispielsweise sicherzustellen, dass eine Person nicht zwischen der Balustrade und einer Decke des Aufzugschachts eingeklemmt werden kann.For this purpose, for example, a balustrade can be provided, which is permanently installed on the roof of the elevator car and, for example, protrudes all around the roof above it at a sufficient height so that people standing on the roof cannot fall over the balustrade. However, the provision of such a balustrade entails additional material and assembly costs and / or the balustrade may have to comply with certain safety regulations, for example, in order to ensure, for example, that a person cannot be pinched between the balustrade and a ceiling of the elevator shaft.
Als Alternative zu einer Balustrade wurde seitens der Anmelderin der vorliegenden Patentanmeldung bereits in der
Aus der
Es kann ein Bedarf an einer alternativen Ausgestaltung einer Aufzugkabine bestehen, bei der geeignete Sicherungsmaßnahmen ein Abstürzen von auf einem Dach der Aufzugkabine befindlichen Personen zuverlässig verhindern. Insbesondere kann ein Bedarf an einer solchen Aufzugkabine bestehen, bei der die Sicherungsmaßnahmen strukturell einfach implementiert sind, kostengünstig realisiert werden können und/oder ein Verfahren der Aufzugkabine innerhalb des Aufzugschachts möglichst minimal behindern.There may be a need for an alternative embodiment of an elevator car, in which suitable safety measures reliably prevent people on a roof of the elevator car from falling. In particular, there may be a need for such an elevator car, in which the safety measures are implemented in a structurally simple manner, can be implemented inexpensively and / or hinder a method of the elevator car within the elevator shaft as minimally as possible.
Einem solchen Bedarf kann durch die Aufzugkabine bzw. die Aufzuganlage gemäß einem der unabhängigen Ansprüche entsprochen werden. Vorteilhafte Ausführungsformen sind in den abhängigen Ansprüchen sowie der nachfolgenden Beschreibung definiert.Such a need can be met by the elevator car or elevator system according to one of the independent claims. Advantageous embodiments are defined in the dependent claims and the description below.
Gemäß einem ersten Aspekt der vorliegenden Erfindung wird eine Aufzugkabine für eine Aufzuganlage vorgeschlagen, die einen Boden, ein Dach und mehrere Seitenwände aufweist. Die Seitenwände definieren dabei in Draufsicht auf die Aufzugkabine eine Außenkontur der Aufzugkabine. Die Aufzugkabine weist ferner zum Bilden einer Absturzsicherungsanordnung mehrere längliche Sicherungsstreben auf, welche von dem Dach der Aufzugkabine aus mit ihrer Längserstreckungsrichtung quer zu einer Kante des Dachs über die Außenkontur der Aufzugkabine nach außen überstehen. Die Sicherungsstreben sind dabei derart in Abständen zueinander auf dem Dach angeordnet, dass ein Hindurchfallen der zu schützenden Person zwischen zwei benachbarten Sicherungsstreben verhindert werden kann.According to a first aspect of the present invention, an elevator car for an elevator installation is proposed which has a floor, a roof and a plurality of side walls. The side walls define an outer contour of the elevator car in a top view of the elevator car. In order to form a fall protection arrangement, the elevator car furthermore has a plurality of elongated securing struts which project outwards from the roof of the elevator car with their longitudinal direction transverse to an edge of the roof beyond the outer contour of the elevator car. The securing struts are arranged at such intervals on the roof that the person to be protected can not fall through between two adjacent securing struts.
Ein zweiter Aspekt der Erfindung betrifft eine Aufzuganlage, die einen Aufzugschacht und eine Aufzugkabine gemäß einer Ausführungsform des zuvor genannten ersten Aspekts der Erfindung aufweist. Die Sicherungsstreben sind dabei derart an der Aufzugkabine angeordnet, dass sowohl eine Beabstandung zwischen benachbarten Sicherungsstreben als auch ein Abstand zwischen einer Sicherungsstrebe einerseits und einer Wand des Aufzugschachts bzw. einer an der Wand angebrachten Aufzugschachtkomponente andererseits für alle Sicherungsstreben kleiner als 30 cm ist.A second aspect of the invention relates to an elevator installation which has an elevator shaft and an elevator car according to an embodiment of the aforementioned first aspect of the invention. The securing struts are arranged on the elevator car in such a way that both a spacing between adjacent securing struts and a distance between a securing strut on the one hand and a wall of the elevator shaft or an elevator shaft component attached to the wall on the other hand is less than 30 cm for all securing struts.
Mögliche Merkmale und Vorteile von Ausführungsformen der Erfindung können unter anderem und ohne die Erfindung einzuschränken als auf nachfolgend beschriebenen Ideen und Erkenntnissen beruhend angesehen werden.Possible features and advantages of embodiments of the invention can, inter alia and without restricting the invention, be viewed as based on the ideas and knowledge described below.
Wie einleitend angemerkt, fordern Sicherheitsregulatorien wie beispielsweise die Europäische Norm EN 81-20:2014, dass Personen, die sich auf dem Dach einer Aufzugkabine befinden, gegen Absturz gesichert sind. Es wurde erkannt, dass sowohl das Vorsehen einer Balustrade als auch das Vorsehen eines Freiraumbegrenzers, wie er in
Es wird daher vorgeschlagen, an der Aufzugkabine mehrere längliche Sicherungsstreben vorzusehen, die im Wesentlichen die Funktion eines solchen Freiraumbegrenzers übernehmen können. Statt, wie in der
Eine Geometrie und/oder Ausgestaltung der länglichen Sicherungsstreben kann geeignet gewählt sein, so dass sie mechanischen Belastungen, wie sie auftreten, wenn eine Person beispielsweise auf die Sicherungsstrebe tritt oder fällt, standhalten kann, ohne sich über ein sicherheitsrelevantes Maß hin zu verformen. Insbesondere sollte die Stabilität der Sicherungsstrebe derart gewählt sein, dass sie sich bei einer solchen auftretenden Belastung nicht so weit verformt, dass Abstände zwischen einer Sicherungsstrebe und einer benachbarten Sicherungsstrebe bzw. einer Wand des Aufzugschachts über ein zulässiges Maß von beispielsweise 30cm vergrößert werden.A geometry and / or configuration of the elongated securing struts can be selected appropriately so that it can withstand mechanical loads such as occur when a person steps or falls on the securing strut, for example, without deforming beyond a safety-relevant dimension. In particular, the stability of the securing strut should be selected such that it does not deform so much under such a load that the distances between a securing strut and an adjacent securing strut or a wall of the elevator shaft are increased by a permissible dimension of, for example, 30 cm.
Gemäß einer Ausführungsform sind die Sicherungsstreben derart strukturell ausgebildet, dass eine Breite einer Sicherungsstrebe, gemessen senkrecht zu ihrer Längserstreckungsrichtung und parallel zur Erstreckungsrichtung des Daches, kleiner ist als das Doppelte einer Höhe der Sicherungsstrebe, gemessen senkrecht zu ihrer Längserstreckungsrichtung und senkrecht zur Erstreckungsebene des Daches. Mit anderen Worten soll ein Aspektverhältnis der Sicherungsstreben möglichst kleiner als 2:1 sein. Vorzugsweise kann ein solches Aspektverhältnis sogar gleich oder kleiner als 1:1 sein, das heißt eine Breite der Sicherungsstrebe ist kleiner als deren Höhe. Ferner kann das Aspektverhältnis auch gleich oder kleiner als 1:2 gewählt sein, das heißt, die Breite der Sicherungsstrebe ist kleiner als die Hälfte der Höhe.According to one embodiment, the securing struts are structurally designed such that a width of a securing strut, measured perpendicular to its longitudinal direction and parallel to the direction of extension of the roof, is smaller than twice a height of the securing strut, measured perpendicular to its longitudinal direction and perpendicular to the plane of extent of the roof. In other words, an aspect ratio of the securing struts should be as small as possible than 2: 1. Such an aspect ratio can preferably even be equal to or less than 1: 1, that is to say a width of the securing strut is less than its height. Furthermore, the aspect ratio can also be selected to be equal to or less than 1: 2, that is to say the width of the securing strut is less than half the height.
Mit anderen Worten soll die Sicherungsstrebe nicht nur länglich sein, das heißt eine größere Erstreckung in ihrer Längserstreckungsrichtung aufweisen als in beiden hierzu orthogonalen Richtungen, sondern auch verhältnismäßig schmal sein, das heißt vorzugsweise eine Breite aufweisen, die kleiner als das Doppelte oder gar das Einfache der Höhe der Sicherungsstrebe aufweist. Solche Sicherungsstreben können mechanisch stabil sein und dabei gleichzeitig auch ein geringes Gewicht aufweisen.In other words, the securing strut should not only be elongated, that is to say have a greater extent in its direction of longitudinal extension than in both directions orthogonal thereto, but also be relatively narrow, that is to say preferably have a width which is less than twice or even simpler than that Height of the securing strut. Such securing struts can be mechanically stable and at the same time also have a low weight.
Außerdem können derartige als Freiraumbegrenzer wirkende Sicherungsstreben über die Außenkontur der Aufzugkabine nach außen überstehen und dadurch verhindern, dass eine Person durch den dort vorhandenen Spalt zwischen Aufzugkabine und Aufzugschachtwand hindurchrutschen kann, ohne jedoch diesen Spalt im Wesentlichen vollflächig auszufüllen. Eine Gesamtaußenkontur der Aufzugkabine, das heißt eine durch die Seitenwände definierte Kontur plus eine durch die seitlich überstehenden Sicherungsstreben ergänzte Kontur wird dabei nicht großflächig vergrößert, sondern die Sicherungsstreben ragen lediglich lokal linear in den Spalt hinein. Da die Gesamtaußenkontur hierbei kleiner bleiben kann als beispielsweise bei den oben genannten herkömmlichen Freiraumbegrenzern, kann ein Luftwiderstand der Aufzugkabine beim Verfahren durch den Aufzugschacht verhältnismäßig gering gehalten werden.In addition, such safety struts acting as free space limiters can protrude outward beyond the outer contour of the elevator car and thereby prevent a person from slipping through the gap between the elevator car and the elevator shaft wall, without, however, filling this gap essentially over the entire area. An overall outer contour of the elevator car, that is to say a contour defined by the side walls plus a contour which is supplemented by the laterally protruding securing struts, is not enlarged over a large area, but rather the securing struts only protrude linearly locally into the gap. Since the overall outer contour can remain smaller than, for example, in the case of the conventional free space limiters mentioned above, an air resistance of the elevator car can be kept relatively low when moving through the elevator shaft.
Gemäß einer Ausführungsform weisen die Sicherungsstreben eine Breite von weniger als 10cm, vorzugsweise weniger als 5cm oder 3cm auf. Ferner können die Sicherungsstreben gemäß einer Ausführungsform eine Höhe von mehr als 2cm, vorzugsweise mehr als 5cm, aufweisen. Sicherungsstreben mit derartigen Abmessungen versprechen eine ausreichende mechanische Stabilität bei geringem Materialeinsatz, geringem Gewicht und geringem Beitrag zu einem Luftwiderstand der Aufzugkabine.According to one embodiment, the securing struts have a width of less than 10 cm, preferably less than 5 cm or 3 cm. Furthermore, according to one embodiment, the securing struts can have a height of more than 2 cm, preferably more than 5 cm. Safety struts with such dimensions promise adequate mechanical stability with low use of materials, low weight and little contribution to air resistance in the elevator car.
Gemäß einer Ausführungsform stehen die Sicherungsstreben mit einer Länge von wenigstens 5cm, vorzugsweise wenigstens 10cm oder stärker bevorzugt wenigstens 20cm, über die Außenkontur der Aufzugkabine nach außen über. Die Sicherungsstreben blockieren hierdurch lokal einen Freiraum oder Spalt angrenzend an die Aufzugkabine. Eine Gesamtlänge der Sicherungsstreben kann dabei deutlich länger sein als der nach außen überstehende Teil, da sich ein Teil der Sicherungsstreben an bzw. auf dem Dach der Aufzugkabine befinden und dort befestigt sein kann.According to one embodiment, the securing struts with a length of at least 5 cm, preferably at least 10 cm or more preferably at least 20 cm, project outward beyond the outer contour of the elevator car. As a result, the securing struts locally block a free space or gap adjacent to the elevator car. A total length of the securing struts can be significantly longer than the part projecting outwards, since some of the securing struts are located on and on the roof of the elevator car and can be fastened there.
Gemäß einer Ausführungsform ist ein seitlicher Abstand zwischen benachbarten Sicherungsstreben größer als eine Breite der Sicherungsstreben. Mit anderen Worten können an dem Dach der Aufzugkabine mehrere Sicherungsstreben vorgesehen sein, die jeweils länglich ausgebildet sind und über die Kontur des Daches bzw. der Aufzugkabine überragen, wobei die Sicherungsstreben in seitlicher Richtung, das heißt in Richtung parallel zu einer Kante des Daches, voneinander beabstandet sind, vorzugsweise in regelmäßigen Abständen, und ein Abstand zwischen benachbarten Sicherungsstreben größer ist als eine Breite einer einzelnen Sicherungsstrebe. Derart weit voneinander seitlich beabstandete Sicherungsstreben können zu einer Reduzierung des Gewichts der Aufzugkabine und/oder einer Verminderung des durch die Sicherungsstreben bewirkten Luftwiderstands beitragen.According to one embodiment, a lateral distance between adjacent securing struts is greater than a width of the securing struts. In other words, a plurality of securing struts can be provided on the roof of the elevator car, each of which is elongated and protrudes beyond the contour of the roof or the elevator car, the securing struts in a lateral direction, that is, in a direction parallel to an edge of the roof are spaced apart, preferably at regular intervals, and a distance between adjacent securing struts is greater than a width of an individual securing strut. So far apart from each other laterally Safety struts can contribute to a reduction in the weight of the elevator car and / or a reduction in the air resistance caused by the safety struts.
Gemäß einer Ausführungsform sind die Sicherungsstreben entlang von Kanten des Dachs in Abständen von weniger als 30cm zueinander angeordnet. Eine solche geringe Beabstandung zwischen benachbarten Sicherungsstreben kann notwendig sein, um zu verhindern, dass eine Person zwischen zwei benachbarten Sicherungsstreben hindurchrutschen kann.According to one embodiment, the securing struts are arranged along edges of the roof at intervals of less than 30 cm from one another. Such a small spacing between adjacent securing struts may be necessary to prevent a person from slipping between two adjacent securing struts.
Gemäß einer Ausführungsform sind die Sicherungsstreben zumindest in einem über die Kante des Dachs überstehenden Bereich als längliche Metallprofile ausgebildet. Insbesondere können sie als längliche Metallhohlprofile ausgebildet sein. Solche Profile können mit dem weiter oben genannten Aspektverhältnis ausgebildet sein. Metallprofile bzw. Metallhohlprofile können eine sehr hohe mechanische Belastbarkeit bei gleichzeitig geringem Gewicht ermöglichen. Als Materialien können verschiedenste Metalle, beispielsweise Stahl, eingesetzt werden.According to one embodiment, the securing struts are designed as elongated metal profiles, at least in an area that projects beyond the edge of the roof. In particular, they can be designed as elongated hollow metal profiles. Such profiles can be designed with the aspect ratio mentioned above. Metal profiles or metal hollow profiles can enable a very high mechanical strength with a low weight. A wide variety of metals, for example steel, can be used as materials.
Generell können die Sicherungsstreben allerdings auch aus anderen Materialien und/oder mit einer anderen strukturellen bzw. geometrischen Ausbildung bereitgestellt werden. Beispielsweise können Sicherungsstreben aus Kunststoffen, insbesondere mechanisch hochbelastbaren faserverstärkten Kunststoffen, ausgebildet werden. Auch Verbundmaterialien können eingesetzt werden.In general, however, the securing struts can also be provided from other materials and / or with a different structural or geometric design. For example, securing struts can be formed from plastics, in particular fiber-reinforced plastics that can withstand high mechanical loads. Composite materials can also be used.
Gemäß einer Ausführungsform können die Sicherungsstreben im Wesentlichen bündig zu einer nach oben gerichteten Oberfläche des Daches angeordnet sein. "Bündig" kann hierbei bedeuten, dass eine nach oben gerichtete Oberfläche einer Sicherungsstrebe sich näherungsweise in einer selben Ebene erstreckt wie die nach oben gerichtete Oberfläche des Daches. "Im Wesentlichen bündig" kann dabei dahingehend ausgelegt werden, dass sich die Erstreckungsebene der nach oben gerichteten Oberfläche der Sicherungsstrebe allenfalls derart geringfügig von der Erstreckungsebene der nach oben gerichteten Oberfläche des Daches in vertikaler Richtung unterscheidet, dass zwischen der Oberfläche des Daches und der Oberfläche der Sicherungsstrebe weder ein signifikanter Absatz nach oben noch ein signifikanter Absatz nach unten auftritt. Ein höchstens generierter Absatz, das heißt ein maximal zulässiges Abweichen von einer idealen Bündigkeit, kann beispielsweise kleiner als 5 cm, vorzugsweise kleiner als 2 cm oder gar kleiner als 1 cm, gewählt sein. Damit kann unter anderem verhindert werden, dass die Sicherungsstrebe für auf dem Dach befindliche Personen zur "Stolperfalle" werden kann.According to one embodiment, the securing struts can be arranged essentially flush with an upward-facing surface of the roof. Here, "flush" can mean that an upward-facing surface of a securing strut extends approximately in the same plane as the upward-facing surface of the roof. "Essentially flush" can be interpreted in such a way that the extension plane of the upward-facing surface of the securing strut differs at most so slightly from the extension plane of the upward-facing surface of the roof in a vertical direction that between the surface of the roof and the surface of the Securing strut neither a significant paragraph up nor a significant paragraph down occurs. For example, a maximum generated paragraph, that is, a maximum permissible deviation from an ideal level, can be smaller than 5 cm, preferably smaller than 2 cm or even smaller than 1 cm. Among other things, this can prevent the safety strut from becoming a "trip hazard" for people on the roof.
Gemäß einer Ausführungsform sind die Sicherungsstreben entlang ihrer Längserstreckungsrichtung gerade. Mit anderen Worten können die Sicherungsstreben als lineare Bauelemente bereitgestellt werden, beispielsweise als gerade Stäbe oder Rohre. Solche Sicherungsstreben können einfach gefertigt und montiert werden.According to one embodiment, the securing struts are straight along their longitudinal direction. In other words, the securing struts can be provided as linear components, for example as straight rods or tubes. Such struts can be easily manufactured and assembled.
Alternativ können die Sicherungsstreben entlang ihrer Längserstreckungsrichtung gekrümmt oder geknickt ausgebildet sein. Die Sicherungsstrebe ist dabei zwar länglich, d.h. ist länger als breit, aber nicht über ihre gesamte Länge hin gerade sondern zumindest in Teilbereichen mit Krümmungen oder Knicken versehen.Alternatively, the securing struts can be curved or kinked along their longitudinal direction. The securing strut is elongated, i.e. is longer than wide, but not straight over its entire length, but at least in some areas with curvatures or kinks.
Beispielsweise kann eine solche Krümmung oder Knick (z.B in Form einer Abwinkelung) derart ausgestaltet sein, dass eine Sicherungsstrebe sich zunächst von dem Dach der Aufzugkabine kommend senkrecht zu dessen Kante nach außen erstreckt, dann jedoch eine Krümmung oder einen Knick aufweist, so dass weiter außen liegende Bereiche der Sicherungsstrebe sich schräg oder gar parallel zur Kante des Daches erstrecken können. Insbesondere angrenzend an Ecken des Daches der Aufzugkabine können mithilfe solcher gekrümmter oder geknickter Sicherungsstreben auch dort vorherrschende Freiräume oder Spalte zwischen der Außenkontur der Aufzugkabine und umgebenden stationären Strukturen des Aufzugschachts ausreichend versperrt werden.For example, such a curvature or kink (for example in the form of a bend) can be designed such that a securing strut initially extends from the roof of the elevator car perpendicularly to its edge, but then has a curvature or kink so that it is further out lying areas of the securing strut can extend obliquely or even parallel to the edge of the roof. In particular, adjacent to corners of the roof of the elevator car, with the aid of such curved or bent securing struts, the free spaces or gaps prevailing there can also be adequately blocked between the outer contour of the elevator car and surrounding stationary structures of the elevator shaft.
Gemäß einer Ausführungsform können die Sicherungsstreben an dem Dach oder an einer der Seitenwände oder sowohl an dem Dach als auch an einer der Seitenwände angebracht sein. Mit anderen Worten kann eine Sicherungsstrebe ausschließlich an dem Dach befestigt sein. Alternativ kann die Sicherungsstrebe ausschließlich an einer der Seitenwände befestigt sein. Als weitere Alternative kann die Sicherungsstrebe sowohl an dem Dach als auch an einer der Seitenwände befestigt sein.According to one embodiment, the securing struts can be attached to the roof or to one of the side walls or both to the roof and to one of the side walls. In other words, a securing strut can only be attached to the roof. Alternatively, the securing strut can only be attached to one of the side walls. As a further alternative, the securing strut can be attached both to the roof and to one of the side walls.
Jede Befestigungsart kann hierbei gewisse Vorteile mit sich bringen. Beispielsweise kann die Sicherungsstrebe bei ausschließlichem Befestigen an dem Dach einfach montiert werden. Bei ausschließlichem Anbringen an einer der Seitenwände kann eine gute Bündigkeit der Sicherungsstrebe mit dem Dach erreicht werden. Eine Kombination aus Befestigung an dem Dach und Befestigung an einer Seitenwand kann einen guten Kompromiss zwischen einfacher Befestigung, guter Bündigkeit und gegebenenfalls eine hohe mechanische Stabilität ermöglichen. Die Sicherungsstrebe kann dabei beispielsweise mit dem Dach und/oder der Seitenwand fest verbunden und/oder in Teilbereichen lediglich auf Druck abgestützt sein.Each type of fastening can bring certain advantages. For example, the securing strut can simply be mounted on the roof if it is only attached. If only attached to one of the side walls, the safety strut can be flush with the roof. A combination of attachment on the roof and attachment to a side wall can allow a good compromise between simple attachment, good flush and possibly high mechanical stability. The securing strut can, for example, be firmly connected to the roof and / or the side wall and / or can only be supported on pressure in partial areas.
Gemäß einer Ausführungsform der Aufzuganlage ist in dem Aufzugschacht wenigstens eine sich vertikal durch den Aufzugschacht erstreckende und/oder stationär in dem Aufzugschacht angebrachte Aufzugschachtkomponente angeordnet. Die Sicherungsstreben sind in diesem Fall an der Aufzugkabine in Bereichen lateral neben der Aufzugschachtkomponente angeordnet.According to one embodiment of the elevator system, at least one elevator shaft component which is vertically extending through the elevator shaft and / or is stationary in the elevator shaft is arranged in the elevator shaft. In this case, the securing struts are arranged on the elevator car in areas laterally next to the elevator shaft component.
Mit anderen Worten können in dem Aufzugschacht beispielsweise stationär angebrachte Führungsschienen vorgesehen sein oder sich vertikal durch den Aufzugschacht erstreckende bewegliche Tragmittel wie beispielsweise Seile oder Riemen erstrecken. Diese Aufzugschachtkomponenten sollen selbstverständlich beim Verfahren der Aufzugkabine innerhalb des Aufzugschachts nicht mit den an der Aufzugkabine vorgesehenen und über deren Außenkontur überragenden Sicherungsstreben kollidieren. Andererseits sollen Freiräume zwischen der Aufzugkabine und der Aufzugschachtwand bzw. den Aufzugschachtkomponenten ausreichend durch die Sicherungsstreben blockiert werden. Durch Vorsehen der Sicherungsstreben in Bereichen lateral neben solchen Aufzugschachtkomponenten können beide Vorgaben erreicht werden.In other words, stationary guide rails can be provided in the elevator shaft, for example, or movable support means, such as ropes or belts, extending vertically through the elevator shaft. These elevator shaft components should of course not collide with the securing struts provided on the elevator cabin and projecting beyond their outer contour when the elevator car is being moved within the elevator shaft. On the other hand, free spaces between the elevator car and the elevator shaft wall or the elevator shaft components should be sufficiently blocked by the securing struts. By providing the securing struts in areas laterally next to such elevator shaft components, both requirements can be achieved.
Zum Schutz der Personen vor Verletzungen können die Sicherungsstreben wenigstens im Spalt befindlichen Abschnitt oder wenigstens im Bereich des freien Endes wenigstens nach oben hin mit einem Schaumstoff oder einem anderen Schutzmaterial versehen sein.To protect people from injuries, the securing struts can be provided with a foam or another protective material at least in the gap in the section or at least in the area of the free end.
