Description

Technical Field

[0001] The invention relates to an elevator system having a mounting bracket for connecting a guide rail to the elevator shaft in the region of a door-side shaft wall of the elevator shaft. Background Art

[0002] Elevators for transporting people and goods contain an elevator car that can be moved up and down in an elevator shaft. The elevator car can be moved in the vertical elevator shaft by means of a sling, for example in the form of load-bearing ropes or load-bearing belts, with the aid of a drive unit. In addition to the elevator car, the elevator usually also comprises at least one counterweight that moves in the elevator shaft in the opposite direction. In order to ensure that the elevator car is guided in a straight line with sufficient accuracy, guide rails fixed in the elevator shaft are used. T-shaped metal profiles have been known for a long time and are commonly used. The guide rails consist of individual guide rail segments that are fixed in the elevator shaft by means of mounting brackets.

[0003] EP1321416 discloses a guide rail structure for an elevator having such a mounting bracket. The mounting bracket is U-shaped, wherein the crossbar of the mounting bracket is fixed to the shaft wall on the door side. In addition, the mounting bracket has two legs, which extend from the ends of the crossbar into the elevator shaft. Guide rails or guide rail segments are fixed to these legs. Summary of the invention

[0004] The object of the invention is to provide an elevator system which enables a simple and reliable installation of guide rails in the elevator shaft. According to the invention, this object and other objects are achieved by an elevator system having the features of claim 1.

[0005] Preferably, the mounting structure can have a first rail fixing section for fixing the guide rail on the side of the mounting structure opposite to the front side or the shaft wall on the door side. The mounting structure can have a second rail fixing section connected to the first rail fixing section for fixing the same guide rail. The first rail fixing section and the second rail fixing section are preferably each provided with at least one mounting opening for fixing the same guide rail. By extending the rail fixing section in this way, the guide rail can be mounted more easily and reliably.

[0006] When a separate mounting component is provided, which includes a second rail fixing segment, it is advantageous if the mounting component is preferably designed as an angle element having two legs arranged at right angles, one leg being formed by the first rail fixing segment and the other leg of the angle element being formed by a profile wall segment which rests flatly or can rest on a horizontal lintel segment.

[0007] For example, the attachment component can be fixed to the lateral support by means of bolts.

[0008] Single or all assembly openings in the first and / or second rail fixing section can be designed as elongated holes. Here, the elongated holes preferably extend in the vertical direction.

[0009] Further advantageous embodiments can be gathered from the dependent claims.

[0010] Further details of the invention and its various advantages will be explained in more detail in the following part of the description.

[0011] The elevator system comprises a vertical elevator shaft, in which the elevator car can move up and down between floors along guide rails. The guide rails are connected to the elevator shaft in the area of ​​the shaft wall on the door side of the elevator shaft, and the elevator system comprises an assembly bracket for this connection corresponding to at least one floor, preferably corresponding to a plurality of floors respectively, and particularly preferably corresponding to each floor, on which the guide rails are fixed. Here, the assembly bracket preferably forms a U-shaped bracket structure with a transverse carrier and two lateral carriers. The transverse carrier extends along the shaft wall on the door side. Two lateral carriers extending from the transverse carrier into the shaft space are preferably arranged at the ends of the transverse carrier. The transverse carrier has a horizontal floor fixing section, which is placed on the horizontal surface of the floor floor and fixed on the floor floor, so that the transverse carrier is advantageously arranged substantially completely in the floor floor. Therefore, in this preferred case, substantially only the lateral carriers are positioned or arranged in the shaft space. Each lateral carrier has a rail fixing section which extends parallel to the shaft wall on the door side and is arranged on the front end of the lateral carrier, and the rail fixing section has at least one assembly opening for fixing the guide rail. By making it possible to arrange the lateral carrier substantially completely in the floor floor, the installation of the elevator system can ensure increased safety for the installer. The invention is also based on the following recognition: only the arrangement of the shaft door is crucial for the positioning of all important components of the elevator car that are related to the mobility of the elevator car. Therefore, the assembly bracket for fixing the guide rail in the elevator shaft must be aligned with the shaft door that has been installed or is to be installed. Therefore, it may be sufficient to fix the assembly bracket only in the area of ​​the floor surface that is substantially oriented horizontally. Another advantage is that the space utilization in the elevator shaft is improved. On the one hand, because the assembly bracket can be fixed on the horizontal floor surface, and therefore substantially only the lateral carrier is arranged in the shaft space and acts on the shaft space. On the other hand, in combination with this, the end-side assembly of the guide rail and the lateral carrier also achieves optimized space utilization. By means of the special mounting bracket, static advantages can also be achieved, since a particularly secure and stable connection of the guide rail to the elevator shaft is achieved in the region of the shaft wall on the door side.

[0012] The main components, namely the transverse carrier of the mounting bracket and the two lateral carriers, can have the following purpose: The transverse carrier comprising at least one floor-fixing section is used to fix the mounting bracket to the elevator shaft. The guide rails are fixed to the lateral carriers.

[0013] The guide rail can be designed as a hollow profile.

[0014] The assembly bracket can be constructed in one piece or in multiple pieces. For example, a one-piece assembly bracket can be designed as a rigid curved part made of sheet metal. The lateral supports and the transverse supports can be made from a common sheet cut to form a common curved part. In a multi-piece variant, at least the lateral supports and preferably also the transverse supports can each be designed as a rigid curved part made of sheet metal. The multi-piece construction increases the variability and has the advantage that the assembly bracket can be easily adapted to different shaft sizes.

[0015] The corresponding lateral carrier can have a horizontal lintel segment extending from the transverse support to the guide rail. In this case, the track-fixing segment can be connected to the horizontal lintel segment at a right angle and, if the transverse carrier is made of sheet metal, can be connected to the horizontal lintel segment via a folded portion. The horizontal lintel segment can, for example, be connected flush to the horizontal floor-fixing segment of the transverse carrier.

[0016] It is particularly advantageous if the corresponding lateral supports are designed as rigid, curved parts made of sheet metal, and the transverse struts have vertical web sections connected to horizontal web sections via folds. This results in a stable and lightweight structure.

[0017] The transverse carrier can have a vertical carrier wall segment adjoining the floor-fixed segment and preferably realized by a fold-over when made of sheet metal, as a stop towards the door-side shaft wall or for contacting against the door-side shaft wall. It is therefore clear that the carrier wall segment is the only element of the transverse carrier that is located in the elevator shaft or arranged in the shaft space. The remaining elements of the transverse carrier, namely the floor-fixed segments, are assigned to the floors or floor panels. The carrier wall segments that preferably extend in the horizontal direction between the lateral carriers can terminate the transverse support towards the elevator shaft.

[0018] The transverse supports should each be arranged substantially completely in the floor. However, it is necessary that, when such mounting brackets are arranged on a plurality of shaft doors of an elevator installation, all of these mounting brackets are aligned with one another according to the travel direction of the elevator car (usually vertically). Dimensional tolerances in the manufacture of the elevator shaft can lead to the transverse supports of the mounting brackets protruding slightly into the shaft space of the elevator shaft. This slight protrusion still meets the requirement that the transverse supports are arranged substantially completely in the floor, or more specifically placed in the vertical projection of the floor.

[0019] The floor-fixing section can have an assembly opening for a screw connection or other fixing means for fixing the assembly bracket to the floor. The assembly opening can be designed in such a way that the assembly bracket can be adjustedly fixed or can be adjustedly fixed to the floor. Adjustably fixed or fixable means that this pre-fixation can be carried out before the final alignment and final fixing of the assembly bracket. This can be achieved, for example, by means of a screw connection, which enables the assembly bracket to perform a horizontal sliding movement in its pre-fixed state. This adjustability makes it possible to pre-fix the assembly bracket to the floor and then align the assembly bracket and finally fix it in the elevator shaft using a straightening element that can be arranged in the elevator shaft.

[0020] The shaft door which can be arranged for mounting on the mounting bracket comprises at least one door leaf. The main components of the shaft door can include the at least one door leaf and / or the threshold of the shaft door and / or at least one door leaf guide rail for guiding the at least one door leaf. In addition, the shaft door can contain coupling elements which are necessary for mechanically coupling the car door to the shaft door. These coupling elements can extend into the cross section of the elevator shaft.

[0021] Another aspect of the present invention may relate to a mounting bracket for the above-mentioned elevator system. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 An elevator system is shown, which is designated as a whole by 1. Elevators are used for vertical transport in multi-storey buildings. The building shown as an example has an elevator shaft 4, in which an elevator car 5 can be moved up and down to the individual floors 10.1, 10.2, 10.3, 10.4. The vertical elevator shaft 4 is limited at its lower end by a shaft bottom. The elevator shaft 4 has a shaft door opening 6 in the form of a wall opening for each floor 10.1, 10.2, 10.3, 10.4. The shaft door opening 6 provides access to the elevator car 5 from the floor. The elevator shaft 4 is laterally limited on the door side by a shaft wall 12.

[0032] The elevator car 5 is moved by means of a sling (not shown here) on which the elevator car 5 is fixed; the sling can be one or more load-bearing ropes or load-bearing belts. The elevator car 5 can be designed to be self-supporting or arranged in a load-bearing structure (e.g. a load-bearing frame), for example. Figure 1 The elevator car 5 shown in the example 5 has a rectangular parallelepiped car body in this simplified example, and comprises a car floor, a car wall and a ceiling. In addition, the elevator car 5 usually has a car door (not shown), which closes the interior space of the elevator car 1 and faces the shaft wall 12 on the door side.

[0033] Guide rails 3 are arranged in the elevator shaft 4 for guiding the elevator car 5. The elevator car 5 can be moved up and down along the guide rails 3 between the floors 10.1, 10.2, 10.3, 10.4. Obviously, the guide rails 3 are connected to the elevator shaft 4 in the region of the shaft wall 12 on the door side by means of a mounting bracket 2, which is marked as 2. For the connection to the guide rails 3, the elevator system 1 comprises, for example, corresponding to the floors 10.1 and 10.4, a mounting structure 2, to which the guide rails 3 are fixed. Each floor 10.1, 10.2, 10.3, 10.4 preferably has such a mounting structure 2, to which the guide rails 3 are fixed. The mounting structure 2 has a horizontal floor-fixing section 15, which rests on a horizontal surface of the floor floor 11 and is fixed to the floor floor. The lateral carriers 8 are connected to the floor-fixing section 15, wherein a rail-fixing section 14 is arranged at the front end of the respective lateral carrier 8, to which the respective guide rail 3 is fixed. The rail fixing section 14 has one or more (not shown here) assembly openings for fixing the guide rail 3. The corresponding fixing mechanism is represented by a short dashed line. In order to extend the interface between the guide rail and the mounting bracket, the mounting structure has a second rail fixing section 31 connected to the first rail fixing section.

[0034] Figure 1 The elevator of can be designed as a traction elevator system 1 and has, in addition to the elevator car 5, at least one counterweight (not shown) which can be moved in the opposite direction to the elevator car 5. Depending on the embodiment of the elevator system 1, special guide rails 3 can be used, which serve as linear guides for the elevator car 5 and the two counterweights. For this purpose, the traction elevator system 1 can have two drives (not shown). In this case, the two drives (for example traction sheave drives) drive the corresponding spreaders and thus move the elevator car 5 and the two counterweights in opposite directions. Each drive is assigned to a counterweight. For guiding the elevator car 5 and the counterweights, two guide rails 3 opposite to each other are provided on both sides of the elevator car 5. For this case, the elevator system can have special guide rails 3, which serve as linear guides for the elevator car 5 and the corresponding counterweights. These guide rails 3 can be manufactured as a one-piece rolled profile. Here, the guide rails 3 can be hollow profiles, for example manufactured as a one-piece rolled profile. Further details about the design of this special guide rail and about the guidance of the car and counterweight with conventional guide rails can be found in WO 2020 / 127787 A1.

[0035] The assembly bracket 30 enables the guide rail 3 to be advantageously fixed in the elevator shaft. The elevator system 1 can include a plurality of assembly structures, each of which is individually fixed to another of the floors 10.2, 10.3, 10.4 located above the lowest floor 10.1. In order to relieve the load of the assembly structure 2 corresponding to the floor 10.1, the guide rail 3 or the guide rail segment fixed to the lowest assembly structure 2 can be placed on the shaft bottom of the elevator shaft 4, in particular supported by the shaft bottom.

[0036] Figure 2 A shaft door opening 6 is shown which is arranged on a floor 11. A shaft door 20 is arranged at this shaft door opening 5. The floor 11 comprises, for example, a horizontal concrete surface 11 and can comprise a tread surface 11' which can be walked on when the floor 10 is used conventionally, the tread surface 10' being formed, for example, by adding a slab.

[0037] Therefore, it is preferred that before the exemplified slab is applied to the concrete surface, the assembly bracket 2 for fixing the guide rail 8 is fixed to the floor 10 by means of the floor fixing section 15. The door sill 21 is arranged above the floor fixing section 15 so that the door sill 21 and the tread surface 11' form a flat extending surface. In addition, the door sill 21 can be integrated into the tread surface 11' in such a way that the tread surface 11' does not form a step or a groove, etc.

[0038] The floor-fixed section 15, which is preferably formed by the transverse carrier 7, ends with a carrier wall section 13, which is designated 13. The carrier wall section 13 forms a vertical stop against the shaft wall 12 on the door side.

[0039] The main components of the shaft door 20 are arranged vertically aligned with the floor 11. This means that these main components of the shaft door 20 are arranged outside the shaft space of the elevator shaft 4. The main components of the shaft door 20 include, for example, a threshold 21, a door leaf 22, and a guide rail 23 for guiding the door leaf 22. The shaft door 20 may also include another door leaf 22, wherein the shaft door 20 may be designed as a central closing type or a telescopic closing type.

[0040] The shaft door 20 can also, for example, comprise a coupling element 24 for mechanical coupling with a coupling unit (not shown) arranged on the elevator car 5. Thus, the elevator car 5 can comprise a car door with a door drive motor. The door drive motor is, for example, provided for synchronously opening / closing the shaft door coupled to the car door and, if necessary, also for unlocking the car door and / or the shaft door. For the shaft door 20, the coupling unit mentioned thus achieves the purpose of establishing an effective coupling between the door drive motor and the shaft door 20. Thus, such a coupling element 24 extends into the shaft space or into the cross section of the elevator shaft 4. As can be seen from Figure 2 It can be seen in the figure that the shaft door 20 is arranged just above the fixed floor section 15 in the vertical projection.

[0041] In addition, from Figure 2 It can be seen that the lateral carrier 8 has a rail fixing section 14 extending parallel to the door-side shaft wall 12 and arranged on the front end of the lateral carrier, which has a mounting opening 18 for fixing the guide rail 3 by means of a fixing means indicated at 25. In this case, in particular a screw connection is suitable as a fixing means.

[0042] The assembly structure 2 has a second rail fixing segment 31 connected to the first rail fixing segment 14, which is used to fix the same guide rail 3. The first rail fixing segment 15 is arranged below the horizontal lintel segment 17, and the second rail fixing segment 31 is arranged on the opposite side of the horizontal lintel segment 17 from a vertical direction, that is, above the horizontal lintel segment 17. For this purpose, a separate mounting component 30 including the second rail fixing segment 31 is provided. The first rail fixing segment 14 and the second rail fixing segment 31 together define a flat "T".

[0043] The mounting member 30 is obviously designed as an angle element with two legs arranged at right angles. Here, one of the legs is formed by the first rail fixing section 15, and the other leg of the angle element is formed by the profile wall section 33 placed on the horizontal crossbeam section 17.

[0044] from Figure 3 It can be seen that the assembly structure is designed as an assembly bracket 2 . Figure 3A mounting frame 2 for an elevator system of the type described above is shown. The mounting frame 2 comprises a transverse carrier 7 and two lateral carriers 8 and 9 extending at right angles to the transverse carrier 7. A guide rail 3 is fixed or can be fixed at the end of each lateral carrier 8, 9.

[0045] The assembly bracket 2 comprises a floor fixing section 15, which is arranged along the transverse carrier 7 and is used to fix the transverse carrier 7 directly to the floor. For example, the assembly bracket 2 can be fixed by means of screws 26 or similar fixing elements that can be anchored in the floor. An assembly opening 19 formed by a hole or a drill hole is arranged in the floor fixing section 15. With the help of such an assembly opening 19, the assembly bracket 2 can be fixed to the floor in an adjustable manner. Therefore, the spacer 29 can be used for adjustable fixing. The adjustment point 27 realizes the adjustability of other assembly brackets 2 arranged in the elevator shaft by means of an exemplary plumb line or a similar straightening element (for example a laser beam suitable for aligning the assembly bracket 2).

[0046] The mounting frame 2 forms a frame structure which is U-shaped in plan view. The "U" shape is formed by a transverse support 7 extending along the shaft wall 12 on the door side and two lateral supports 8, 9 extending from the transverse support into the shaft space.

[0047] Figure 4 The mounting bracket 2 is shown fastened to a floor 11. The mounting bracket 2 is fastened directly to the concrete surface of the floor 11 by means of its transverse supports 7. The transverse supports 7 have folds for forming vertical support wall segments 13, which can be arranged at the end of the floor delimited by the elevator shaft. The support wall segments 13 form a stop for the shaft wall on the door side and can terminate the transverse supports 7 towards the elevator shaft. The support wall segments 13 extend clearly in the horizontal direction between the lateral supports 8 and 9. When the mounting bracket 2 is correctly fastened to the floor, the folds or support wall segments 13 preferably extend vertically downwards, so that the guide rails that can be fastened to the mounting bracket 2 can be kept at a minimum distance from the floor by means of the folds.

[0048] The transverse carrier 7 has a floor fixing section 15, which is placed on the horizontal plane of the floor 11 and is fixed to the floor or fixed to the floor, so that the transverse carrier 7 is basically completely arranged in the floor 11. Therefore, basically only the lateral carriers 8, 9 are arranged in the shaft space. Each lateral carrier 8, 9 has a rail fixing section 14 extending parallel to the shaft wall 12 on the door side and having at least one assembly opening 18 for fixing the schematically drawn guide rail 3. The guide rail 3 is designed as a T-shaped rail profile, for example. Of course, guide rail profiles of different shapes can also be fixed to the assembly bracket 2. The special end-side connection scheme of the guide rail 3 and the assembly bracket 2 is particularly suitable for the guide rail 3 designed as a hollow guide rail.

[0049] like Figure 4 As further shown, each of the two rail fixing segments 14; 31 has a mounting opening 18; 32.

[0050] Figure 5 The structural details of another variant of the mounting bracket 2 for the elevator system 1 for mounting on the shaft door opening are shown. The mounting bracket 2 forms a U-shaped bracket structure together with a transverse carrier 7 and two lateral carriers 8, 9. The transverse carrier 7 extends in a first direction, which is defined by the shaft wall on the door side when the mounting bracket 2 is mounted. The transverse carrier 7 then extends along the shaft wall on the door side. The two lateral carriers 8, 9 extending from the transverse carrier 7 each extend in a second direction, which extends at right angles to the first direction mentioned. The transverse carrier 7 has a floor fixing section 15, which can be fixed on a horizontal plane or ground plane on the floor 11 in such a way that the transverse carrier 7 can be arranged substantially completely in the floor 11. Thus, substantially only the lateral carriers 8, 9 can be arranged in the shaft space of the elevator shaft. Each of the lateral carriers 8, 9 has a rail fixing section 14 extending parallel to the first direction and arranged at the free end of the lateral carrier, which has two mounting openings 18. The two mounting openings 18 are used to fasten the guide rail (not shown). Instead of the two mounting openings 18 shown as an example, it is of course also conceivable that each rail fastening section 14 has only one mounting opening 18 or even more than two mounting openings. At least one mounting opening 18 is designed as an elongated hole, which has a favorable effect in terms of mounting. Fastening screws or fixing bolts for fastening the guide rail can be accommodated in the elongated holes.

[0051] The lateral carriers 8, 9 and the transverse carrier 7 are each designed as a rigid curved component made of a metal sheet (e.g., a steel sheet). Instead of a multi-piece structure, the assembly bracket 2 can also be designed as a single piece and made of a single or common sheet cut section. The transverse carrier 7 has a vertical carrier wall segment 13 connected to the floor fixed segment 15 and formed by a folded portion as a stop for the shaft wall facing the door side. The corresponding lateral carriers 8, 9 have a horizontal lintel segment 17 and a vertical lintel segment 16. Here, the expressions for orientation (horizontal and vertical) refer to the assembled situation. The vertical lintel segment 16 is integrally connected to the horizontal lintel segment 17 by a folded portion. The two lintel segments 16 and 17 extend from the transverse carrier 7 to the guide rail. The carrier wall segment 13 is arranged on the front end of the lateral carriers 8, 9, respectively. In the present case, the rail fixing section 14 adjoins the horizontal lintel section 17 at right angles and is connected to the horizontal lintel section 17 via a fold. The floor fixing section 15 forms a plate-shaped support structure that extends over the entire length (length viewed in relation to the aforementioned first direction) of the transverse carrier 7. The floor fixing section 15 is designed to be large enough to rest on a horizontal floor. It is advantageous if the floor fixing section 15 acts on a horizontal surface on the floor that is at least as large as the total cross-sectional area of ​​the guide rail.

[0052] Figure 5 Another mounting bracket 2 for an elevator system 2 is shown. Two mounting openings 18 designed as elongated holes extending in the vertical direction are arranged in the first rail fastening section 15. At least one mounting opening 32 designed as an elongated hole extending in the vertical direction is provided in the second rail fastening section 31.

[0053] The respective lateral carriers 8, 9 with the horizontal lintel segment 17 and the first rail fixing segment 15 are formed by a common component, which is preferably designed as a rigid, curved part made of sheet metal. The mounting component 30, which includes the second rail fixing segment 31, is a separate component mounted on the lateral carriers 8, 9. In the present case, the mounting component 30 is fixed to the lateral carriers 8, 9 by means of bolts. The mounting component 30 is designed as an angle element with two legs 15, 33 arranged at right angles. The angle element also has a supporting wall 38 located between the first rail fixing segment and the profile wall segment 33.

[0054] Especially from Figure 6As can be seen in the figure, the assembly structure 2 for fixing the guide rail 3 includes a connecting component 34 extending along the first rail fixing segment 15 and the second rail fixing segment 31 and connecting the two rail fixing segments 15 and 31 to each other. The connecting component 34 has a T-shaped embedded component 35 on one side, which can be introduced into the long hole 32 of the first rail fixing segment 15 or the second rail fixing segment 31 and supported in the long hole. On the opposite side, there are two through holes 18 for fixing screws, which are used to fix on the guide rail 3.

[0055] from Figure 8 The advantages of the special fixing structure with two track fixing segments can be seen. The guide rail 3 is designed as a hollow profile, preferably as a rolled profile. In the current case, it is basically a guide rail of the type known from WO2020 / 127787A1. On the guide rail 3 or on the docking structure 36 corresponding to the guide rail 3, a plurality of prefabricated receptacles 37.1, 37.2, 37.3 arranged one after the other for fixing screws 28 are provided. Thanks to the extension of the second track fixing segment 31, even in the transition area between the two track segments, a sufficiently strong and reliable fixation using at least two screws 28 can be ensured.
