This also allows for use of same/similar fixation bracket units for different kinds of lift shafts; this also allows for adjustment and compensation of e.g. unevenness of a/the respective wall of the lift shaft.
- According to one embodiment the respective fixation bracket unit resp. its constituent components is/are made of sheet metal material, especially galvanized sheet metal e.g. having a thickness of 2mm. This also allows for a slim and cost-effective design.

This configuration also allows for minimum packing volume in context with handling and logistics for a plurality of fixation bracket units.
- A folding mechanism allowing for a swivel motion from laterally outside to the inside also facilitates mounting/coupling of a/the preassembled fixation bracket unit to all three guide rails at the same time, especially by arranging the first bracket part and the first coupling at the respective cabin guide rail and by unfolding both the second and third bracket parts from laterally outside to the inside resp. to an orthogonal alignment with respect to the cross direction (main extension of the first bracket part), in order to define a U-shape.
- According to one embodiment the respective fixation bracket unit consists of parts (preferably only three parts) which can be folded into one another, wherein the respective fixation bracket unit exhibits fastening means which are arranged and configured such that a/the swivel axis for a/the folding mechanism of parts of the fixation bracket unit is defined by the fastening means.

- According to one embodiment the respective fixation bracket unit consists of parts which can be folded into one another, wherein the respective fixation bracket unit exhibits fastening means which respectively interact with an elongated hole provided in arms of the respective fixation bracket unit. This configuration also allows for easy handling and favourable assembly tolerance (positional variation) in at least one spatial direction with respect to the respective lift shaft wall (e.g. in order to compensate for any lift shaft wall irregularities).
- According to one embodiment the respective fixation bracket unit exhibits fastening means which define a/the swivel axis for a/the folding mechanism, wherein the fastening means remain mounted when pretensioning means are to be mounted for coupling the respective counterweight guide rail. This further facilitates handling and mounting
- According to one embodiment pretensioning means provided for coupling the respective counterweight guide rail also provide for interconnecting means for interconnecting (in pairs) parts of the fixation bracket unit. This further facilitates handling and mounting.
- According to one embodiment the respective fixation bracket unit is symmetric (symmetric construction/design) with respect to the cross direction and preferably also with respect to the vertical direction, especially with respect to the position of cut outs (especially boreholes) predefining the cabin guide rail's cross position with respect to the counterweight guide rail's position. Such symmetric configuration also allows for use of the fixation bracket unit in more flexible manner, e.g. for opposite sides of the lift shaft or for mirror-inverted eccentricity of the cabin guide rail.
- According to one embodiment a/the first coupling of the respective fixation bracket unit for coupling the cabin guide rail is defined by pretensioning means defining the position of at least one pretensioning element (especially a force-fitting pretensioning element) pressing the cabin guide rail to the fixation bracket unit, especially such that the coupling is twist-proof against twisting of the cabin guide rail along its longitudinal axis. This provides for advantageous coupling means for the cabin guide rails.

- According to one embodiment the respective fixation bracket unit provides for functionality of routing and supporting at least one cable or conduct, especially by means of at least one retainer plate which is fastened at one part of the fixation bracket unit, especially at a/the first bracket part. This further enhances functional integration of the fixation bracket units to the elevator arrangement in view of broad functionality ensured by only few different parts.
- According to a second aspect of the invention, fixation units provide for advantageous fixation and positioning of a/the further cabin guide rail. In particular, the above mentioned object is also solved by an elevator arrangement exhibiting at least one cabin for a lift shaft and at least one drive unit, wherein the at least one cabin is coupled with the drive unit by means of at least one traction means interacting with the drive unit, wherein the at least one cabin is guided by means of at least one cabin guide rail, wherein the elevator arrangement exhibits at least one guide rail for at least one counterweight, wherein the elevator arrangement exhibits a plurality of fixation units each configured for directly fixing a/the further cabin guide rail to at least one further side of the lift shaft each in a specific/individual height position within the lift shaft in at least one fixing point, especially comprising two parts respectively, namely a first L-angle profile (first part) and a second L-angle profile (second part). Such configuration also provides for advantageous combination with (application together with) the fixation bracket units according to the present disclosure.
- In other words: According to one embodiment the elevator arrangement further exhibits a plurality of fixation units each configured for directly fixing a further cabin guide rail (especially vis-à-vis the cabin guide rail) to at least one further side (especially wall) of the lift shaft each in a specific/individual height position within the lift shaft in at least one fixing point, especially comprising two parts respectively, namely a first L-angle profile (first part) and a second L-angle profile (second part), wherein the respective fixation unit preferably defines at least two fixing points in two fixing planes which extend orthogonally with respect to each other. This also allows for adapting the fixation concept described above also for fixing the further cabin guide rail. In particular, it has been found that each fixation unit can preferably be composed of two times the same part (especially L -form); the constellation of these two parts may also provide for adjustment of the position of the respective cabin guide rail; in other words: the fixation unit may provide for tolerance and adjustment functionality at least in one spatial direction such that depending on the lift shaft's dimensions, the desired relative position of the further cabin guide rail can be adjusted by means of the same type of fixation units.
- According to one embodiment the respective fixation unit is configured for providing/allowing assembly tolerance (positional variation) in at least one spatial direction, especially by at least 25% of distance variation with respect to the respective distance to the wall of the lift shaft (preferably at least 35%) preferably in a/the horizontal direction orthogonal to the cross direction, especially by means of elongated holes (slots) and/or oversized boreholes. This also allows for use of same/similar fixation units for different kinds of lift shafts; this also allows for adjustment and compensation of e.g. unevenness of a/the respective wall of the lift shaft.
- For example, the elevator arrangement is equipped with three types of fixation units each providing for at least 25% of distance variation, thereby providing for an adjustment range of e.g. ca. 100mm for the distance between the guide rail and the wall (e.g. between 25 and 135mm).
- According to one embodiment the respective fixation unit resp. its constituent components is/are made of sheet metal material, especially galvanized sheet metal e.g. having a thickness of 3mm. This also allows for a slim and cost-effective design.
- According to a further aspect of the invention, fixation bracket units and/or fixation units according to the present disclosure provide for favourable fixation/assembly also within a pit of the lift shaft. In particular, the above mentioned object is also solved by an elevator arrangement exhibiting at least one cabin for a lift shaft and at least one drive unit, wherein the at least one cabin is coupled with the drive unit by means of at least one traction means interacting with the drive unit, wherein the at least one cabin is guided by means of at least one cabin guide rail, wherein the elevator arrangement exhibits at least one guide rail for at least one counterweight, wherein the elevator arrangement exhibits at least one fixation bracket unit and/or at least one fixation unit configured for being arranged and fixed within a pit of the lift shaft, especially fixed at the bottom/ground of the lift shaft, thereby defining a/the starting position of the respective guide rail. Preferably, fixation is carried out by fixing the respective fixation bracket unit or fixation unit in a second fixing plane resp. horizontal plane (instead of fixing it within a first fixing plane resp. vertical plane), wherein the second fixing plane can favourably be defined by a section of an L-profile or angle profile of the respective fixation (bracket) unit. In other words: According to one embodiment one fixation bracket unit of the plurality of fixation bracket units and optionally also one fixation unit of a/the plurality of fixation units is/are arranged within a pit of the lift shaft, especially fixed at the bottom/ground of the lift shaft, thereby defining a/the starting position of the respective guide rail. This further facilitates handling and fixation, especially in view of few different parts which can be used for both fixation on the wall and fixation on the ground. In other words: One of the fixation bracket units is mounted within the pit on the bottom, thereby also marking the counterweight's position or zone. Thus, this fixation bracket unit fixed on the ground provides for at least two functions: defining a starting point/position for the installation of the guide rails, and providing for a visual and spatial separation of the pit in order to prevent technicians from walking under/near the counterweight. In other words: There is no need for any additional security provisions within the pit in context with the counterweight, rather, such use of the fixation bracket units may overcome any risk assessment requirements. This configuration also facilitates overcoming prior art requiring a counterweight protection device (e.g. sheet metal) in the pit for protecting and preventing a technician from walking under/near the counterweight.
- According to one embodiment an L-angle profile (first or second part) of one of the fixation units of a/the plurality of fixation units is used for fixing a/the further cabin guide rail at the bottom/ground within the pit of the lift shaft. This configuration also allows for reducing the complexity of required parts, thereby further facilitating handling and mounting. Preferably, the structural composition of the respective fixation unit consists of two L-angle profiles which can be fastened together by means of fastening means allowing for at least 25% of distance variation of the distance between the wall of the lift shaft and the respective guide rail. In other words: According to the invention, the configuration of both the fixation bracket unit(s) and the fixation unit(s) allows for using same/similar parts for the fixation of the respective cabin guide rail(s) not only on the wall (at least one first fixing plane resp. vertical plane) but also within the pit (second fixing plane resp. horizontal plane). Using the fixation unit (resp. only one part of the fixation unit) for the fixation of the further cabin guide rail in the pit resp. on the ground also allows for defining a/the starting point for the guide rail installation.
- In particular, the above mentioned object is also solved by a fixation bracket unit for an elevator arrangement according to the present disclosure, wherein the (respective) fixation bracket unit is processed by providing a first bracket part made of sheet metal material (especially by bending) and second and third bracket parts made of sheet metal material (especially by bending), wherein the second and third bracket parts are similar or at least exhibit a mirror-inverted design, wherein the respective fixation bracket unit is configured for predefining both the cabin guide rail's cross position and lateral distance respectively with respect to the counterweight guide rail's position(s), wherein these three bracket parts can be fastened together in pairs, especially such that fastening means respectively provide for a swivel axis for a folding mechanism ensuring a folded arrangement of at least two or three parts of the fixation bracket unit. This configuration provides for above mentioned advantages.
- In particular, the above mentioned object is also solved by use of a plurality of fixation bracket units for fixing a cabin guide rail and two counterweight guide rails to at least one side (especially wall) of a lift shaft of an elevator arrangement in at least two fixing points by coupling both the cabin guide rail and the counterweight guide rails respectively in a specific/individual height position within the lift shaft by means of first and second couplings, wherein both the cabin guide rail's cross position and the lateral distance are defined with respect to the counterweight guide rails' positions by means of the respective fixation bracket unit, especially use of said fixation bracket units in an elevator arrangement according to the present disclosure.
