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.
  • the securing strut 21 therefore does not protrude outwardly from the roof 11, but only linearly, approximately as a one-dimensional structure.

  • 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.
