Definitions
- the present invention relates to an elevator installation.
- the present invention relates to an elevator installation.
- the present invention relates to an elevator installation.
- Invention a counterweight for an elevator system.
- an elevator car In an elevator installation, an elevator car is typically typically shifted vertically along a travel path between different floors or levels within a building. At least in tall buildings, an elevator type is usually used in which the elevator car is held by rope-like or belt-type suspension means and is moved within an elevator shaft by moving the suspension means by means of a drive machine. In order to at least partially compensate for the load of the elevator car to be moved by the drive machine, a counterweight is usually attached to an opposite end of the suspension means. This counterweight has at least the same mass as the elevator car. As a rule, the mass of the counterweight exceeds that of the elevator car by half of the payload permissible to be carried by the elevator car. Depending on the type of elevator, several counterweights and / or several elevator cars can also be provided in an elevator system.
- both the elevator car and the counterweight have an essentially cuboid geometry.
- An example of a correspondingly designed elevator system is described in EP 1894876 A1.
- the base area can be understood to mean a cross-sectional area along a horizontal plane, which must be provided in a building for accommodating the elevator system.
- the total base area to be provided depends, among other things, on a base area of the elevator car, a base area of the counterweight and, if appropriate, a base area which is suitable for
- Elevator components are needed, with the help of which, for example, the elevator car and the counterweight is held within the elevator shaft and / or at hers
- Relocation movements can be performed.
- the portion of the base area that is to be provided for the elevator car usually results inevitably from one for the concept to be designed
- Elevated system predetermined conveying capacity i.e. a number of people who should find space in the elevator car.
- the base area of the counterweight could be kept small and a height of the counterweight, i.e. a dimension of the counterweight orthogonal to this base area, could be large in order to give the counterweight sufficient volume overall to be of sufficient mass to compensate for the cabin load to be able to.
- the height of the counterweight could possibly be greater than the height of the elevator car.
- sufficient height had to be available in the elevator shaft in order to be able to accommodate the counterweight at any position into which it could be moved during the operation of the elevator system.
- counterweights could be used which consisted of a material with a particularly high density.
- counterweights could be made of steel instead of concrete, so that they could have a significantly smaller volume with the same mass.
- a counterweight for an elevator installation is proposed.
- the counterweight has an asymmetrical cross-section in a horizontal sectional plane.
- an elevator installation which has at least one elevator car, at least one guide rail and at least one counterweight according to an embodiment of the first aspect of the invention.
- elevator systems have mostly had a substantially cuboid geometry.
- a counterweight had a rectangular base.
- the cross section of the counterweight was rectangular in a horizontal section plane.
- Such a rectangular cross-section has mirror symmetries. Counterweights with such a simple geometry can be manufactured with little effort.
- Cross-sectional area deviate by more than 5%, preferably more than 10%, from a symmetrical cross-section.
- the asymmetry relates purely to the geometry, that is, not to weight distributions within the counterweight.
- Base areas that are available in the elevator shaft of the elevator system can be adapted.
- the asymmetrical configuration of the counterweight makes it possible to accommodate the counterweight in a space-saving manner in those areas of an elevator shaft that are neither for the elevator car nor
- the counterweight proposed herein generally has two opposite end faces, two opposite longitudinal flanks and two opposite top surfaces.
- the two end faces can be flat. Furthermore, the two end faces can run parallel to one another.
- the two longitudinal flanks could also be flat, but it may be preferred not to design at least one of the two longitudinal flanks flat. In particular, it can be preferred that the two longitudinal flanks do not run parallel to one another, at least in partial areas.
- both the end faces and the longitudinal flanks extend in the vertical direction.
- Each of the longitudinal flanks extends from an edge of a first end face to an edge of the opposite second end face.
- the top surfaces can be flat and / or run parallel to one another.
- the top surfaces generally extend in a horizontal direction or in a horizontal plane.
- the proposed counterweight is not cuboid. Instead, the geometry of the counterweight can be at least one of its longitudinal flanks and / or one that is not parallel to one another, in particular due to a non-planar configuration
- the counterweight has a greater first width on a first end side than a second width on an opposite second end side.
- the counterweight is designed asymmetrically in such a way that it is wider on the first end side than on the second end side.
- the first width can
- the counterweight can be “L” shaped in cross section. The width is measured in each case in the horizontal section plane in a direction parallel to one of the end faces.
- the counterweight is less wide on its second end face, other components of the elevator system can be accommodated in the elevator shaft on this end face adjacent to the counterweight.
- the counterweight has two opposite ones
- Longitudinal flanks which each extend between the first and the second end face. At least one of these longitudinal flanks can be concave.
- At least one of the longitudinal flanks of the counterweight, which connect the first to the second end face can be concave rather than flat.
- concave can be understood to mean a geometric configuration in which the respective longitudinal flank deviates inward from a flat configuration, i.e. towards the opposite longitudinal flank. In other words, the concave longitudinal flank is closer to the opposite one
- longitudinal flank as a virtual flat longitudinal flank used for comparison, which connects the same edges of the end faces. It can be preferred that in particular that longitudinal flank of the counterweight which is directed towards the elevator car is of concave design. Due to the concave design, at least one of the longitudinal flanks of the
- a kind of recess can be created in the area of the counterweight in which other components of the elevator system, i.e. in particular, for example, a guide rail and / or a strut holding the guide rail can be accommodated.
- the counterweight has a first and a second longitudinal flank, which each extend between a first and a second end face.
- the first longitudinal flank runs essentially as a plane from the first end face to the second end face and in particular the first longitudinal flank is in the
- the front side describes those surfaces of the counterweight that have a maximum distance from one another in a horizontal sectional plane along a longer main axis of the cross section.
- the end faces are free of additional construction elements.
- the two end faces and the straight longitudinal flank are flat.
- three shaft walls are each parallel to one of the
- End faces or the longitudinal flank In order to make optimum use of the shaft, it is advantageous for the shaft walls to have the same preferably minimum tolerance distance from the end faces or the longitudinal flank. Thus, the two end faces and the longitudinal flank fit within a tolerance distance in an area of the elevator shaft that is spanned by three shaft walls.
- the two longitudinal flanks are preferably parallel to one another in a region adjacent to the first end face.
- the two longitudinal flanks are preferably parallel to one another in a region adjacent to the second end face.
- an intermediate region can be formed on the counterweight between the first end face and the second end face, in which the counterweight has a smaller width than the first width.
- a holding device can be arranged on the counterweight, via which the counterweight is attached to a guide rail and along the Guide rail can be moved guided.
- At least one of the longitudinal flanks of the counterweight can be designed in such a way that a kind of indentation is formed in the counterweight in the intermediate region mentioned, away from its first end face.
- the counterweight has a smaller thickness at the indentation in the intermediate area than at its first end face. There is thus space in this indentation to create one
- the guide rail is intended to hold or support the counterweight.
- the guide rail should be designed in such a way that the counterweight, when it is displaced vertically in the elevator shaft, is held on the guide rail and guided by it.
- a special holding device is provided on the counterweight in the indentation formed in the intermediate region.
- This holding device can interact, for example, in a form-fitting manner with the guide rail and can be designed in such a way that the counterweight on the holding device
- Guide rail is held and guided by the guide rail can be moved along a planned travel path.
- the counterweight on its concave longitudinal flank in the intermediate region can be designed in such a way that a part of the surface of the counterweight running there is oriented obliquely.
- “oblique” can be understood to mean that the longitudinal flank in question does not connect the wider first end face to the narrower second end face along a shortest connecting line, but rather has a concave indentation in which the part of the surface of the counterweight running there does not run along this shortest connecting line, but is aligned obliquely to this.
- the sloping surface can be flat.
- the inclined surface can also be slightly curved, as long as they are obliquely average in relation to the shortest mentioned
- the counterweight can interact with a surface of a guide rail that is also oriented obliquely and preferably runs parallel to the inclined surface of the counterweight. Due to the inclined orientation of these surfaces, the guiding properties of the guide rail can be improved with respect to the counterweight guided thereon. In particular, it can be achieved that the counterweight can neither be moved freely parallel to one of its end faces nor parallel to the longitudinal flanks. Instead, it can
- Counterweight be held in both mutually perpendicular directions on the sloping surface of the guide rail. In this way, the counterweight can be prevented, for example, from unwanted lateral swinging within the elevator shaft.
- the only holding device of the counterweight is arranged exclusively in the area of the inclined surface.
- the holding device can be configured to hold the counterweight at at least two spatially separated positions on the guide rail and to guide it along at least two spatially separated guide tracks.
- the holding device cannot only hold the counterweight at a single position on the guide rail and along a single one
- the holding device can be configured in such a way that the counterweight can be held by the holding device at two laterally spaced positions and is guided by the holding device during a vertical movement along two laterally spaced guideways.
- the holding device can reliably hold the counterweight on the guide rail and can guide it with respect to two directions that are not parallel to one another. In this way, the holding device
- the counterweight can be formed predominantly with a first material in a first region, in which it has a greater width, and predominantly with a second material in a second region, in which it has a smaller width.
- the second material has a greater density than the first material.
- the second material can have a density that is at least 50%, preferably at least 100%, higher than the first material.
- the first material can be concrete and the second material can be a metal, in particular steel.
- a counterweight for an elevator installation has an asymmetrical cross section in a horizontal sectional plane.
- the counterweight is predominantly formed with a first material in a first region in which it has a greater width and is predominantly formed with a second material in a second region in which it has a smaller width.
- the counterweight can be viewed as being composed of at least two areas.
- the counterweight has a larger width, which can correspond, for example, to the first width mentioned above on the first end face.
- the counterweight has a smaller width, which can correspond, for example, to the second width mentioned above on the second end face.
- the width of the counterweight can be constant within one of these ranges.
- the width of the counterweight can vary within one or both areas, in which case at least one average width in the first area is larger than an average width in the second area. If the two areas have approximately the same length and height, the different widths result in a larger volume for the first area than for the second area. In the event that the two regions consist of the same material, this would result in an inhomogeneous weight distribution along a longitudinal direction of the counterweight.
- a denser material can be used in the smaller volume second area than in the larger first area. Due to the use of this denser material, the second area can have a similar or even the same weight as the first area despite the smaller volume.
- the second region can be predominantly or even completely made of metal, in particular for example made of steel with a density of approximately for example
- the first area can be predominantly or even completely made of concrete, which typically has a density of 2 to 3 g / cm 3 .
- the use of different materials in the counterweight and the uneven distribution of these materials within the counterweight can at least partially compensate for the asymmetrical geometric configuration of the counterweight in such a way that a largely balanced weight distribution in relation to the central axis, which runs parallel to the end faces of the counterweight and is arranged at the transition between the first area and the second area can be achieved.
- the use of materials of different densities in the two areas means that a focus of the counterweight, despite different volumes of the two areas, is roughly where the first area borders the second area.
- Such a homogenization of the weight distribution within the counterweight can be used in such a way that the counterweight can be used, for example, with a
- Holding device which is attached to the counterweight approximately where the first Area adjoins the second area, attached to a guide rail and can be guided along this.
- This position can thus correspond to the intermediate range described above.
- this position can be arranged approximately centrally in the longitudinal direction on the counterweight, ie within 20% or within, for example, 10% on this side or beyond the geometric center of the counterweight in its longitudinal direction.
- the asymmetrical counterweight described can advantageously be used in several ways.
- the use of the asymmetrical counterweight can enable a particularly space-saving arrangement of the counterweight in the elevator installation and thus a small installation space for the elevator installation.
- the counterweight and a strut which hold a guide rail guiding the counterweight on one
- the elevator shaft wall is anchored, each having an outer contour in a cross section along a horizontal sectional plane, a first virtual rectangle surrounding the outer contour of the counterweight and being minimally large, and a second virtual rectangle surrounding the outer contour of the strut and being minimally large overlap.
- the elevator system with the counterweight which has an asymmetrical cross-section in a horizontal section plane.
- the elevator system further comprises a strut which holds a guide rail holding the counterweight on one Anchor shaft wall anchored.
- the strut and the counterweight have an outer contour in a cross section along a horizontal sectional plane, with a first virtual rectangle which surrounds the outer contour of the counterweight and is minimally large, and a second virtual rectangle which surrounds the outer contour of the strut and is minimally large , overlap each other.
- a guide rail within the elevator system can be anchored laterally to an elevator shaft wall of the elevator shaft using a strut that usually runs horizontally.
- Both the strut and the guide rail have a horizontal cross section, i.e. projected onto a horizontal plane, a certain outer contour.
- This outer contour can, but need not necessarily, be rectangular.
- the smallest possible rectangle can be placed around each outer contour, that is to say the outer contour is completely enveloping but minimal in size.
- the counterweight itself does not have a rectangular cross-section, but can be enveloped by a minimally large rectangle. In this rectangle, called the first rectangle, there remain partial areas that are not filled by the asymmetrical counterweight.
- the strut and preferably also the guide rail can be at least partially or even completely accommodated.
- the minimally large rectangle enveloping the strut and the minimally large rectangle enveloping the counterweight can at least partially overlap one another.
- both the at least one elevator car and the at least one counterweight can be held on the guide rail such that they are guided in a displacement movement along the guide rail.
- the elevator installation can be equipped with one or more guide rails, with one on each individual guide rail
- Counterweight as well as an elevator car are held and are guided in their movement along the guide rail. This is made possible in particular by the special configuration of the counterweight proposed here. As a result, a number of guide rails to be kept available in the elevator installation can be reduced, as a result of which Both costs for the elevator installation and an effort during its installation can be reduced.
- a number of guide rails can be equal to a number of counterweights.
- a single counterweight can be held on a single guide rail and moved along it.
- the elevator installation can be equipped with two separate counterweights and, accordingly, two separate guide rails. Each of the counterweights can be held and guided on only one of the guide rails. Between the two
- the travel path of the elevator car can be on guide rails.
- the travels of the two counterweights can each
- the elevator car can preferably be held and guided on the same guide rails as the counterweights. Overall, this can reduce the number of guide rails to be maintained and installed.
- the guide rail can have two guide tracks that are spatially separated from one another and directed in different directions.
- a holding device with two guide shoes can be formed on the counterweight, each of the
- Guide shoes is configured to support the counterweight on the guide rail and with the guide rail the counterweight on one of the
- a single guide rail can be structurally designed in such a way that it has two vertically extending and laterally spaced apart
- Guideways are formed.
- the two guideways are oriented in different directions, i.e. the surfaces formed by the respective guideways point in non-parallel directions.
- Interacting guideways can then be on the counterweight
- Holding device formed with two appropriately aligned guide shoes be.
- Each of the guide shoes is suitably designed and aligned in order to support itself and the counterweight connected to it along one of the guide tracks on the guide rail.
- the guide shoes are each designed to hold the guide weight guided along the respective guide tracks on the guide rail when the counterweight moves vertically.
- the counterweight is not only guided laterally in a single direction, but is guided in two directions that are not parallel to each other. As a result, a more stable lateral guidance can be achieved in the event of displacement movements of the counterweight.
- the counterweight can have a height, measured in a direction parallel to a longitudinal direction of the guide rail, which is less than or equal to 130%, preferably less than or equal to 110% or even less than or equal to 100%, of a height of the elevator car.
- the counterweight can have a height that is at most slightly larger than the height of the elevator car.
- the height of the counterweight is preferably at most the same as the height of the elevator car.
- a height of the elevator shaft of an elevator installation essentially only needs to be dimensioned based on the length of the travel path of the elevator car and the height of the elevator car.
- the elevator shaft does not need as with some conventional ones
- Elevator systems alone are therefore provided with a greater height in order to be able to accommodate a counterweight whose height is significantly greater than that of the elevator car in order to be able to achieve a sufficient mass for the counterweight with a small footprint.
- the asymmetrical counterweight can optimally utilize or fill the areas of a base area that are not to be kept free in the elevator shaft for the elevator car or other elevator components.
- the base area of the counterweight can be relatively large. In this way, on the other hand, the counterweight can already attain a sufficient mass with a relatively small height of, for example, less than 2.5 m in order to largely compensate for the load arising from the elevator car and its possible payload.

- a recess 29 is formed on the inner longitudinal flank 23 of the counterweight 3 approximately in the region of the geometric center of the longitudinal flank 23.
- Indentation 29 can also be viewed as an intermediate region 31 in which the counterweight 3 has a smaller width than the first width B1
- a holding device 33 is arranged on the counterweight 3 between the intermediate region 31.
- the counterweight 3 is attached to the respectively adjacent guide rail 9 via the holding device 33 and can be moved in a guided manner along the guide rail 9.

- the two guideways 35 are aligned at a 90 ° angle to one another, i.e. arranged on mutually perpendicular flanks of the square guide rail 9 in the Profd.
- the holding device 33 has two guide shoes 34, which can be designed, for example, as sliding shoes 37.
- Each of the slide shoes 37 is designed to cooperate with one of the guide tracks 35 and in this way to support the counterweight 3 via the slide shoe 37 and the guide track 35 on the guide rail 9 and thereby with the guide rail 9 in this way

- the asymmetrical counterweight 3 can be regarded as being composed of at least two areas 43, 45.
- the counterweight 3 In a first area 43, the counterweight 3 has a larger width, for example the first width B 1 as on the first end face 17.
- the counterweight 3 In a second area 45, the counterweight 3 has a smaller width than this.

- the counterweight 3 can be held and guided on a single guide rail 9.
- the counterweight 3 was concave on at least one longitudinal flank 23, so that the entire counterweight 3 approximately has an “L” shape in the horizontal cross section. Because of this concave configuration, the counterweight 3 can interact via a holding device 33 on two surfaces with surfaces of the guide rail 9 or the guide tracks 35, 39, 57, 59 provided there. This design enables a significantly stiffer connection between the counterweight 3 and the guide rail 9.
