[0004] Advantageous fixing techniques are needed to fix these guide rails in the elevator shaft, especially with regard to ease of operation. Summary of the invention

[0006] The objects of the invention are solved by the features of the independent claim. Advantageous features are indicated in the dependent claims. Features of a dependent claim can be combined with features of the independent claim as well as with features of another dependent claim.

[0007] According to a first aspect of the invention, a fixing bracket unit provides advantageous fixing and positioning. In particular, the object is solved by an elevator installation having at least one car and at least one drive unit for an elevator shaft, wherein the at least one car is coupled to the drive unit by at least one traction device interacting with the drive unit, the at least one car is guided by at least one car guide rail, the elevator installation has at least one guide rail for at least one counterweight, the elevator installation has a plurality of fixing bracket units, which at least one fixing point at a specific / individual height position in the elevator shaft couples both the car guide rail and the at least one counterweight guide rail to be fixed to at least one side (especially a wall) of the elevator shaft, wherein each fixing bracket unit is configured to preset a lateral position of the car guide rail relative to the position where the counterweight guide rail is located, and wherein each fixing bracket unit is further configured to preset a lateral distance of the car guide rail relative to the position where the counterweight guide rail is located. In other words: each fixing bracket unit is configured to preset the relative position of the guide rails relative to each other in two spatial horizontal directions. This configuration also facilitates the positioning of the guide rails relative to each other, and this configuration is also conducive to efficient and simple operation and installation. Advantageously, the individual fixing bracket units also provide for assembly tolerances (position variations) with respect to at least one elevator shaft wall, in particular for compensating for any irregularities at / in / in the elevator shaft wall.

[0008] In particular, the invention provides an advantageous technical solution for fixing the guide rails to the wall of the elevator shaft and for positioning the guide rails relative to each other. The individual fixing bracket units may also be configured as a foldable bracket, which is particularly advantageous with regard to easy transport and easy handling in the elevator shaft. Furthermore, the individual fixing bracket units may also provide a (first / second) coupling element, preferably configured as a single clip or clamp (or, only a single clip or clamp for each side of the guide rail), for coupling the individual guide rails, in particular in combination with at least one cutout in the individual bracket part (which cutout may also define the relative position of the guide rails). Furthermore, the individual fixing bracket units may also have at least one receiving section for receiving the respective counterweight guide rail, such as an undercut or a notch; such a configuration may further facilitate installation, handling and relative positioning.

[0009] According to one embodiment, each fixing bracket unit has at least one receiving section for receiving and positioning the corresponding counterweight guide rail within the predetermined said lateral distance. This configuration further facilitates installation and positioning. In particular, the receiving section can have an undercut or a notch. Advantageously, the receiving section is configured to predetermine the said lateral distance of the car guide rail by form fit.

[0010] According to one embodiment, an elevator installation has two counterweight guide rails, wherein each fixing bracket unit is configured to couple a (first) car guide rail and two counterweight guide rails to at least one side (particularly a wall) of the elevator shaft, wherein each fixing bracket unit is configured to predetermine the lateral position of the car guide rail relative to the position of the two counterweight guide rails, in particular the lateral position of an eccentric car guide rail arranged eccentrically relative to half the lateral distance between the counterweight guide rails. This allows coupling and fixing of three guide rails by only one unit (fixing bracket unit).

[0011] In particular, at least one car can be guided by at least two car guide rails (a car guide rail and an opposite another car guide rail) located on opposite sides of the car, wherein each fixing bracket unit is coupled to the car guide rail and the other guide rail is coupled via the fixing unit.

[0012] According to one embodiment, each fixing bracket unit has at least one cutout, in particular a bore, which predetermines the lateral position of the car guide rail relative to the position of the counterweight guide rail. This also makes possible an advantageous positioning with the drive region of the drive unit and with the traction means which should extend laterally from the car guide rail.

[0013] According to one embodiment, in a vertical top view, each fixing bracket unit is U-shaped according to a predetermined arrangement, wherein each fixing bracket unit is configured to couple the car guide rail at a first side (especially the outer side) of the fixing bracket unit and couple the counterweight guide rail at a second side (especially the inner side) of the fixing bracket unit, wherein preferably each fixing point is located laterally outward of the counterweight guide rail. This further facilitates operation and installation and provides effective structural support.

[0014] According to one embodiment, the individual fixing bracket units are configured to be fixed to the wall of the elevator shaft by only one single fixing device, in particular an anchor bolt, on each side or at each fixing point, in particular by two fixing devices. This further facilitates handling and installation. For example, the fixing device is configured to anchor the individual fixing bracket units in cracked or uncracked concrete of the wall and / or in a support beam or any type of support rail, such as a metal support rail, provided in the wall.

[0015] According to one embodiment, the individual fixing bracket units are configured to provide / allow assembly tolerances (position variations) in at least one spatial direction, in particular at least 25% (preferably at least 35%) with respect to a distance variation in a respective distance to a wall of the elevator shaft or with respect to a respective extension of the second bracket part / third bracket part, in particular a distance variation in a horizontal direction perpendicular to the transverse direction, in particular by means of elongated holes (slots) and / or oversized bores. This also allows the use of the same / similar fixing bracket units for different types of elevator shafts; this also allows adjustment and compensation of, for example, unevenness of the respective walls in the elevator shaft.

[0016] According to one embodiment, the individual fixing bracket units or their components are made of sheet metal, in particular galvanized sheet metal, for example with a thickness of 2 mm. This also allows a thin and cost-effective structure to be designed.

[0017] According to one embodiment, each fixed bracket unit consists of curved parts (curved components), in particular only three curved parts, namely a U-shaped central part (first bracket part), a first side part (second bracket part or first arm) and a second side part (third bracket part or second arm), preferably the second side part is similar to the first side part. This further facilitates handling and installation, and this configuration also provides a thin and light design. Advantageously, these curved parts can be preassembled by the fixing device.

[0018] According to one embodiment, each fixed bracket unit has a U-shape consisting of a first bracket part (central part) and two arms (second bracket part and third bracket part), and consists of three parts that can be folded into each other. This configuration also allows easy handling and advantageous pre-assembly.

[0019] According to the invention, the individual fixing bracket units consist of curved parts that can be folded onto one another, in particular curved parts that can be folded onto one another in the pre-assembled state, in particular from the outside to the inside at the sides. This further facilitates handling and installation, in particular the process of coupling the fixing bracket unit to the corresponding counterweight guide rail. This configuration also allows the fixing bracket unit to have a minimal packaging volume in terms of handling and logistics.

[0020] A folding mechanism that allows lateral rotational movement from the outside to the inside also facilitates the simultaneous installation / coupling of the preassembled fixed bracket unit to all three guide rails, in particular by arranging the first bracket part and the first coupling member on the corresponding car guide rails and by unfolding the second bracket part and the third bracket part laterally from the outside to the inside or aligning them perpendicular to the transverse direction (the main extension direction of the first bracket part) to define a U-shape.

[0021] According to one embodiment, preferably, each fixed support unit consists of only three parts that can be folded into one another, wherein each fixed support unit has fixing devices that are arranged and configured such that the rotation axis of the folding mechanism of the parts in the fixed support unit is defined by the fixing devices. This further facilitates logistics and transportation as a whole and in particular also facilitates manual handling and installation.

[0022] According to one embodiment, each fixing bracket unit has fixing means, which respectively interact with an elongated hole provided in the arm of the respective fixing bracket unit. This configuration also allows easy handling and favorable assembly tolerances (position variations) in at least one spatial direction relative to the respective elevator shaft wall (e.g. in order to compensate for any elevator shaft wall irregularities).

[0023] According to one embodiment, each fixing bracket unit has fixing devices which define the rotation axis of the folding mechanism, wherein the fixing devices remain installed when the preload device is installed to couple the corresponding counterweight rail. This further facilitates handling and installation.

[0024] According to one embodiment, the pre-tensioning means for coupling the respective counterweight rails also provide interconnecting means for interconnecting the parts of the (paired) fixing bracket units. This further facilitates handling and installation.

[0025] According to one embodiment, the individual fixing bracket units are symmetrical in the transverse direction (symmetrical structure / design), preferably also in the vertical direction, in particular symmetrical with respect to the position of the predetermined cutouts (in particular drillings) in the transverse position of the car guide rail relative to the position of the counterweight guide rail. Such a symmetrical configuration also allows a more flexible use of the fixing bracket units, for example for opposite sides of the elevator shaft or for mirror-inverted eccentricities of the car guide rails.

[0026] According to one embodiment, the first coupling element of the respective fixing bracket unit for coupling to the car guide rail is defined by a pretensioning device which defines the position of at least one pretensioning element, in particular a force-fitting pretensioning element, pressing the car guide rail against the fixing bracket unit, in particular making the coupling torsion-proof against torsion of the car guide rail along its longitudinal axis. This provides an advantageous coupling device for the car guide rail.

[0027] According to one embodiment, the second coupling element of the respective fixed support unit for coupling to the (corresponding) counterweight guide rail is defined by a pretensioning device which defines the position of pressing the counterweight guide rail against at least one pretensioning element (in particular a force-fitting pretensioning element) of the fixed support unit, in particular such that the coupling is torsion-proof against torsion of the car guide rail along its longitudinal axis. This also provides an advantageous coupling device for the counterweight guide rail.

[0028] According to one embodiment, each fixing bracket unit is configured to preassemble at least one prestressing device or prestressing element of the second coupling part, in particular by providing at least one elongated hole (slot) or oversized bore hole for another prestressing device or prestressing element of the second coupling part. This also facilitates the installation of the fixing bracket unit in the elevator shaft, in particular by predetermining at least one coupling point.

[0029] According to one embodiment, each fixing bracket unit defines at least two fixing points in two fixing planes, which extend perpendicularly to each other, in particular are defined at two free ends of the fixing bracket unit. This also allows the fixing bracket unit to be used both on the wall and on the floor of the elevator shaft, i.e. the fixing in the pit of the elevator shaft can be ensured by the same fixing bracket unit configuration.

[0030] According to one embodiment, each fixed support unit provides a routing and support function for at least one cable or wire, in particular by at least one retaining plate fixed to a part of the fixed support unit, in particular to the first support part. This further enhances the functional integration of the fixed support unit in the elevator installation to ensure that a wide range of functions are achieved with only a few different parts.

[0031] According to a second aspect of the invention, a fixing unit provides an advantageous way for fixing and positioning a further car guide rail. In particular, the above-mentioned object can also be solved by an elevator device having at least one car for an elevator shaft and at least one drive unit, wherein at least one car is coupled to the drive unit via at least one traction device interacting with the drive unit, and at least one car is guided by at least one car guide rail, wherein the elevator device has at least one guide rail for at least one counterweight, and the elevator device has a plurality of fixing units, each of which is configured to fix the further car guide rail directly to at least one other side of the elevator shaft at least at one fixing point at each specific / individual height position, each fixing unit in particular consisting of two parts, namely a first L-shaped profile (first part) and a second L-shaped profile (second part). This configuration also provides an advantageous combination (together application) with a fixing bracket unit according to the present disclosure.

[0032] In other words: According to one embodiment, the elevator installation further has a plurality of fixing units, each fixing unit being configured to fix a further car guide rail (in particular opposite to the car guide rail) directly to at least one further side (in particular a wall) of the elevator shaft at at least one fixing point in each specific / individual height position, in particular each fixing unit consisting of two parts, namely a first L-shaped profile (first part) and a second L-shaped profile (second part), wherein preferably the respective fixing unit defines at least two fixing points in two mutually perpendicular fixing planes. This also allows the above-described fixing concept to be adapted for fixing the further car guide rail. Particularly preferably, it has been found that each fixing unit can consist of two identical parts (in particular L-shaped); these two-part configurations can also provide for adjusting the position of the respective car guide rail; in other words: the fixing unit can provide a tolerance and adjustment function in at least one spatial direction, so that, depending on the size of the elevator shaft, the desired relative position of the further car guide rail can be adjusted by the same fixing unit type.

[0033] According to one embodiment, the individual fixing units are configured to provide / allow an assembly tolerance (position variation) in at least one spatial direction, in particular preferably at least 25% (preferably at least 35%) of the distance variation in the corresponding distance relative to the elevator shaft wall in a horizontal direction perpendicular to the transverse direction, in particular by means of elongated holes (slots) and / or oversized boreholes. This also allows the use of the same / similar fixing units for different types of elevator shafts; this also allows adjustment and compensation of unevenness of, for example, the elevator shaft wall.

[0034] For example, an elevator installation is equipped with three types of fixing units, each of which provides at least 25% of the distance variation, thereby providing an adjustment range of, for example, approximately 100 mm for the distance between the guide rail and the wall (for example between 25 and 135 mm).

[0035] According to one embodiment, the individual fixing units or their constituent parts are made of sheet metal, in particular galvanized sheet metal, for example with a thickness of 3 mm. This also allows a thin and cost-effective structure to be designed.

[0036] According to another aspect of the invention, a fixing bracket unit and / or fixing unit according to the disclosure provides an advantageous fixing / installation in a pit of an elevator shaft. In particular, the above-mentioned object can also be solved by an elevator installation having at least one car for an elevator shaft and at least one drive unit, wherein the at least one car is coupled to the drive unit via at least one traction device interacting with the drive unit, the at least one car is guided by at least one car guide rail, wherein the elevator installation has at least one guide rail for at least one counterweight, and the elevator installation has at least one fixing bracket unit and / or at least one fixing unit arranged and fixed in the pit of the elevator shaft, in particular fixed to the bottom / ground of the elevator shaft, so that the starting position of the corresponding guide rail is defined. Preferably, the fixing is implemented by fixing the respective fixing bracket unit or fixing unit in a second fixing plane or horizontal plane (rather than in a first fixing plane or vertical plane), wherein the second fixing plane can advantageously be defined by the cross section of an L-shaped profile or angle profile of the respective fixing (bracket) unit. In other words: according to one embodiment, one of the plurality of fixed support units and optionally another of the plurality of fixed units are arranged in the pit of the elevator shaft, in particular fixed to the bottom / ground, thereby defining the starting position of the corresponding guide rail. This further facilitates handling and fixing, especially considering that a small number of parts can be used for fixing on the wall and fixing on the ground. In other words: one fixed support unit is installed at the bottom of the pit, thereby also marking the position or area of ​​the counterweight. Therefore, such a fixed support unit fixed to the ground provides at least two functions: defining the starting point / position of the guide rail installation, and providing a visual and spatial separation for preventing a technician from walking into / approaching the counterweight. In other words: no additional safety measures for the counterweight are required in the pit, on the contrary, such use of fixed support units can overcome any risk assessment requirements. This configuration also facilitates overcoming the need in the prior art to set a counterweight protection device (such as a metal plate) in the pit to prevent a technician from walking into / approaching the counterweight.

[0037] According to one embodiment, the L-shaped profile (first part or second part) of one of the plurality of fixing units is used to fix the other car guide rail on the bottom / ground of the elevator shaft pit. This configuration also allows to reduce the complexity of the required components, thereby further facilitating handling and installation. Preferably, the structural composition of each fixing unit consists of two L-shaped profiles, which can be fixed to each other by fixing means, which allows a distance variation of at least 25% of the distance between the wall of the elevator shaft and the corresponding guide rail. In other words: according to the invention, the configuration of both the (multiple) fixing bracket unit and the (multiple) fixing unit allows to use the same / similar components that are not only fixed to the wall (at least one first fixing plane or vertical plane), but also fixed in the pit (second fixing plane or horizontal plane). Using a fixing unit (or, only a part of a fixing unit) to fix the other car guide rail in the pit / on the ground also allows to define the starting point of the guide rail installation.

[0038] In particular, the above objects can also be solved by a fixed support unit for an elevator installation according to the disclosure, wherein (each) fixed support unit is manufactured by providing a first support part made of sheet metal (especially by bending) and a second support and a third support part made of sheet metal (especially by bending), wherein the second support and the third support part are similar or at least exhibit a mirror-inverted design, and each fixed support unit is configured to a predetermined lateral position of the car guide rail and a lateral distance relative to the position of the counterweight guide rail, and the three support parts can be fixed together in pairs, so that the fixing device provides a rotation axis for the folding mechanism, respectively, ensuring a folded arrangement of at least two or three parts of the fixed support unit. This configuration provides the above advantages.

[0039] In particular, the above-mentioned purpose can also be solved by using a plurality of fixing bracket units, which are used to fix the car guide rail and the two counterweight guide rails to at least two fixing points on at least one side (especially a wall) of the elevator shaft of the elevator device by coupling the car guide rail and the counterweight guide rail through a first coupling piece and a second coupling piece at a specific / individual height position in the elevator shaft, wherein the lateral position of the car guide rail and the lateral distance of the counterweight guide rail position are defined by each fixing bracket unit, wherein each fixing bracket unit consists of bent parts that can be folded into each other, in particular the use of the fixing bracket units in the elevator device according to the present disclosure.
