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 comprise 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 a load rope or a load belt, with the aid of a drive unit. In addition to the elevator car, the elevator usually comprises at least one counterweight, which moves in the opposite direction in the elevator shaft. 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 long been known and commonly used. The guide rails consist of individual guide rail segments, which are fixed in the elevator shaft by means of mounting brackets.

[0003] EP1321416 discloses a guide rail arrangement for an elevator having such a mounting bracket. Such a mounting bracket has a U-shaped shape, wherein the transverse carrier 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 transverse carrier into the elevator shaft. Guide rails or guide rail segments are fixed to these legs. The transverse carrier and the legs are arranged accordingly in the cross section of the elevator shaft, thereby reducing the available shaft space, that is, reducing the free cross section of the elevator shaft suitable for the mobility of the elevator car. The cross section of the elevator shaft refers to the surface of the cavity defined by the elevator shaft in the top view or in the vertical direction. The shaft space, which is usually rectangular in the top view, i.e. the cross section of the elevator shaft, is bounded by the shaft wall. Summary of the invention

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

[0005] The elevator system comprises a vertical elevator shaft, in which the elevator car can move up and down along the guide rails between floors. The guide rails are connected to the elevator shaft in the area of ​​the shaft wall on the door side of the elevator shaft, wherein the elevator system comprises a mounting bracket for at least one floor, preferably for a plurality of floors respectively and particularly preferably for each floor for the connection, on which the guide rails are fixed. The mounting 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 flat on the horizontal plane of the floor floor and fixed on the horizontal plane, so that the transverse carrier is advantageously arranged substantially completely within 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 extending parallel to the shaft wall on the door side and arranged at the front end of the lateral carrier, and the rail fixing section has at least one assembly opening for fixing the guide rail. Since the lateral carrier can be arranged basically completely within the floor floor, the installation of the elevator system can ensure improved safety for the assembler. The present invention is also based on the following recognition, that is, only the arrangement of the shaft door is decisive for the positioning of all components of the elevator car that mainly relate to the mobility of the elevator car. Therefore, the assembly bracket must be aligned relative to the installed or to be installed shaft door in order to fix the guide rail in the elevator shaft. Therefore, it is sufficient to fix the assembly bracket only in the area of ​​the floor surface that is basically aligned horizontally. Another advantage is that the space utilization of the elevator shaft is improved. On the one hand, because the assembly bracket can be fixed on the horizontal floor surface, and therefore basically only the lateral carrier is arranged in the shaft space and loads the shaft space. On the other hand, in combination with this, the guide rail is mounted on the lateral carrier at the end side, which also achieves optimized space utilization. Static advantages can also be achieved with a special mounting bracket, since a particularly secure and stable connection of the guide rail to the elevator shaft is achieved in the region of the door-side shaft wall.

[0006] The main components, namely the transverse carrier of the mounting bracket and the two lateral carriers, have the following purpose: The transverse carrier, which comprises at least one floor-fixing section, serves to fix the mounting bracket to the elevator shaft. The guide rails are fixed to the lateral carriers.

[0007] The guide rail can be designed as a hollow profile.

[0008] For simple assembly, it may be advantageous if at least one assembly opening is configured as an elongated hole in the rail fastening section. A fastening screw or a fastening pin for fastening the guide rail can be accommodated in the elongated hole.

[0009] The mounting bracket can be designed as a single piece or as a multi-piece bracket. A single-piece mounting bracket can be designed, for example, as a rigid curved part made of sheet metal. In this case, the lateral supports and the transverse supports can be made from a common sheet material cut-out 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 design increases the variability and has the advantage that the mounting bracket can be easily adapted to different shaft dimensions.

[0010] The corresponding lateral carrier can have a horizontal crosspiece section extending from the transverse carrier to the guide rail. In this case, the rail fastening section can be connected to the horizontal crosspiece section at a right angle and, if the transverse carrier is made of sheet metal, it can be connected to the horizontal crosspiece section via a fold-over. The horizontal crosspiece section can, for example, be connected flush to the horizontal floor fastening section of the transverse carrier.

[0011] It can be particularly advantageous if the respective lateral supports are designed as rigid, curved parts made of sheet metal, and the transverse supports have vertical web sections which are connected to horizontal web sections via folds. In this way, a stable but lightweight structure is obtained.

[0012] The transverse carrier can have a carrier wall section adjacent to the floor-fixed section and preferably formed by a fold-over when made of sheet metal as a stop for the door-side shaft wall or for contacting the door-side shaft wall. It is therefore clear that the carrier wall section 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 sections, are assigned to the floors or floor panels. The carrier wall section that preferably extends in the horizontal direction between the lateral carriers can end the transverse carrier in the direction of the elevator shaft.

[0013] The transverse supports should each be arranged substantially completely within the floor. However, it is necessary that, when arranging corresponding such mounting brackets at a plurality of shaft doors of an elevator installation, all of these mounting brackets are usually aligned with one another vertically in the direction of movement of the elevator car. Quality tolerances during the manufacture of the elevator shaft can result in the transverse supports of the mounting bracket protruding slightly into the shaft space of the elevator shaft. This slight protrusion still meets the requirement that the transverse member be arranged substantially completely within the floor, or more precisely within the vertical projection of the floor.

[0014] The floor fixing section can have an assembly opening for a screw connection or other fixing means for fixing the assembly bracket on the floor. The assembly opening can be designed so that the assembly bracket can be adjusted to be fixed or can be adjusted to the floor. Adjustable fixing or fixability means that this pre-fixation can be achieved before the final alignment and subsequent final fixing of the assembly bracket. This can be achieved, for example, by means of a screw connection, which allows the assembly bracket to slide horizontally in its pre-fixed state. Here, the floor fixing section, which is exemplarily configured as a through opening, is configured larger than required by the size of the bolt, by means of which the assembly bracket is fixed or can be fixed on the floor. For example, the pad formed according to the washer causes the pre-fixation or final fixing of the assembly bracket on the floor by its degree of compression on the assembly bracket by means of the bolt. This adjustability allows the assembly bracket to be pre-fixed on the floor and then aligned and finally fixed in the elevator shaft by means of a guide element that can be arranged in the elevator shaft.

[0015] Simple and reliable assembly can be achieved if the floor fastening section has a plate-shaped and preferably flat supporting structure formed from a metal sheet, which extends over the entire length of the transverse carrier.

[0016] Here, the floor fixing section can act on a horizontal surface on the floor which is at least as large as the cross section of the guide rail. Due to the sufficiently large horizontal support surface, the guide rail can be reliably installed in the shaft from the shaft wall on the door side.

[0017] The shaft door can be arranged in a vertical projection above the floor-fixed section. The floor-fixed section of the transverse carrier can thus be used as a suitable platform which supports the shaft door on the bottom side.

[0018] The shaft door which can be arranged on the mounting bracket for installation comprises at least one door leaf. The main components of the shaft door can include at least one door leaf and / or a threshold 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 in order to mechanically couple the car door to the shaft door. These coupling elements can extend into the cross section of the elevator shaft.

[0019] Another aspect of the invention relates to an assembly bracket for an elevator system, in particular for an elevator system as described above, for assembly at a shaft door opening. The assembly bracket is preferably designed as a bracket structure which is U-shaped in a top view and has a transverse carrier extending in a first direction and two lateral carriers extending from the transverse carrier and extending in a second direction extending transversely and preferably perpendicularly to the first direction. Preferably, the transverse carrier and the two lateral carriers are arranged relative to each other in such a way that they define the "U-shape". If the assembly bracket is assembled in the elevator system, the first direction is defined by the shaft wall on the door side, along which the direction extends. The transverse carrier has a floor fixing section which can be fixed on the horizontal plane of the floor floor, so that the transverse carrier can be arranged substantially completely within the floor floor, while the lateral carriers are arranged substantially only in the shaft space. Each lateral carrier has a rail fixing section extending parallel to the first direction, the rail fixing section having at least one assembly opening for fixing a guide rail guiding the elevator car. In this case, the rail fastening section can be arranged at the front end of the transverse carrier or at the end facing away from the transverse carrier. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1An elevator system is shown, which is denoted as a whole by 1. Elevators are used for vertical transportation in multi-storey buildings. The building shown by way of example has an elevator shaft 4, in which an elevator car 5 can be moved up and down to the respective floors 10.1, 10.2, 10.3, 10.4. The vertical elevator shaft 4 is delimited at its lower end by a shaft bottom. The elevator shaft 4 has a shaft door opening 6 in the form of a wall perforation for each floor 10.1, 10.2, 10.3, 10.4. The shaft door opening 6 defines the entrance from the floor into the elevator car 5. The elevator shaft 4 is delimited laterally by a shaft wall 12 on the door side.

[0028] The movement of the elevator car 5 is achieved by means of a sling (not shown here), to which the elevator car 5 is fixed; the sling may be one or more load-bearing ropes or load-bearing belts. The elevator car 5 may, for example, be self-supporting or may be arranged in a load-bearing structure, for example a load-bearing frame. Figure 1 The elevator car 5 shown in the figure has a cuboid car body and comprises a car bottom, a car wall and a ceiling. In addition, the elevator car 5 usually has a car door (not shown) which closes the interior of the elevator car 1 and faces the shaft wall 12 on the door side.

[0029] Guide rails 3 are provided 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. The guide rails 3 are connected to the shaft 4 in the region of the shaft wall 12 on the door side by means of a mounting bracket 2, which is indicated by 2. For the connection with the guide rails 3, the elevator system 1 comprises, for example, for the floors 10.1 and 10.4, a mounting bracket 2, to which the guide rails 3 are fixed. Preferably, each floor 10.1, 10.2, 10.3, 10.4 has such a mounting bracket 2, to which the guide rails 3 are fixed. The mounting bracket 2 has a horizontal floor fixing section 15, which is placed and fixed on the horizontal surface of the floor 11 of the floor. The lateral carriers 8 are connected to the floor fixing section 15, wherein a rail fixing section 14 is provided at the front end of the respective lateral carrier 8, to which the respective guide rail 3 is fixed. The rail fastening section 14 has one or more mounting openings (not shown here) for fastening the guide rail 3. The corresponding fastening means are schematically indicated by short dashed lines.

[0030] Figure 1The elevator of the present invention can be constructed as a traction elevator system 1 and has, in addition to the elevator car 5, at least one counterweight (not shown) that can move in the opposite direction to the elevator car 5. According to one embodiment of the elevator system 1, special guide rails 3 can be used, which serve as linear guides not only for the elevator car 5 but also for the two counterweights. The traction elevator system 1 can have two (not shown) drives for this purpose. In this case, the two drives (for example, drive pulley drives) drive the corresponding slings and thus move the elevator car 5 and the two counterweights in the opposite direction. Each drive is associated with one of the counterweights. In order to guide the elevator car 5 and the counterweight, two guide rails 3 facing each other are arranged on both sides of the elevator car 5. In this case, the elevator system can have special guide rails 3, which serve as linear guides for both the elevator car 5 and the respective 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 such special guide rails and their use for guiding the car and counterweight via a common guide rail can be found in WO 2020 / 127787 A1.

[0031] The mounting bracket 30 enables an advantageous fixing of the guide rail 3 in the elevator shaft. The elevator system 1 can comprise a plurality of mounting brackets, wherein each of these mounting brackets is individually fixed to another of the floors 10.2, 10.3, 10.4 located above the bottom floor 10.1. In order to relieve the load of the mounting bracket 2 assigned to the floor 10.1, the guide rail 3 or the guide rail segment fixed to the mounting bracket 30 can be placed on the shaft bottom of the elevator shaft 4, in particular supported by the shaft bottom.

[0032] Figure 2 The shaft door opening 6 arranged on the floor 11 is shown. A shaft door 20 is arranged on this shaft door opening 5. The floor 11 comprises, for example, a horizontal concrete surface 11 and can include a stepping surface 11' that can be stepped on during normal use of the floor 10, wherein the stepping surface 10' that can be stepped on can be formed, for example, by adding a slab.

[0033] The mounting bracket 2 for fixing the guide rail 8 is therefore preferably fixed to the floor slab 10 by means of the floor fixing section 15 before applying the seamless surface to the concrete surface, for example. The threshold 21 is arranged above the floor fixing section 15 so that the threshold 21 forms a flat surface with the tread surface 11 '. In addition, the threshold 21 can be integrated into the tread surface 11 ' so that the tread surface 11 ' does not form a shoulder or a groove or the like.

[0034] from Figure 2It can also be seen that the floor-fixed section 15, which is preferably formed by the transverse carrier 7, is terminated by a carrier wall section 13, which is indicated by 13. The carrier wall section 13 forms a vertical stop which bears against the shaft wall 12 on the door side.

[0035] The main components of the shaft door 20 are arranged within the vertical alignment of the floor 11. That is, 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. In addition, the shaft door 20 can include another door leaf 22, wherein the shaft door 20 can be constructed to be closed centrally or telescopically closed.

[0036] Furthermore, the shaft door 20 can, for example, comprise a coupling element 24 for mechanically coupling to 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 provided, for example, for synchronously opening / closing a car door coupled to the car door and, if necessary, also for unlocking the car door and / or the shaft door. The coupling unit described accordingly fulfills the purpose of establishing an effective connection between the door drive motor and the shaft door 20 in relation to the shaft door 20. Thus, such a coupling element 24 projects into the shaft space or into the cross section of the elevator shaft 4.

[0037] As from Figure 2 As can be seen, the shaft door 20 is arranged in vertical projection just above the fixed floor section 15 .

[0038] In addition, Figure 2 As can be seen in the figure, the lateral carrier 8 has a rail fastening section 14 extending parallel to the door-side shaft wall 12 and arranged at the front end of the lateral carrier, which has a mounting opening 18 for fastening the guide rail 3 by means of a fastening means indicated at 25. In this case, in particular screw connections are suitable as fastening means.

[0039] Figure 3 A mounting bracket 2 for an elevator system of the aforementioned type is shown. The mounting bracket 2 comprises a transverse carrier 7 and two lateral carriers 8 and 9 extending perpendicularly to the transverse carrier 7. A guide rail 3 is fixed or can be fixed to each end of the lateral carriers 8, 9.

[0040] The mounting bracket 2 comprises a floor fixing section 15, which is arranged on the floor floor along the transverse carrier 7 for direct fixing of the transverse carrier 7. The mounting bracket 2 can be fixed, for example, by means of bolts 26 or similar fixing elements to be anchored on the floor floor. In the floor fixing section 15, a mounting opening 19 formed by a hole or a drill hole is provided. With the aid of such a mounting opening 19, the mounting bracket 2 can be adjustably fixed on the floor floor. Therefore, the spacer 29 can be used for adjustably fixing. The adjustment point 27 allows adjustability for other mounting brackets 2 arranged in the elevator shaft by means of an exemplary plumb line or a similar alignment element (such as a laser beam suitable for aligning the mounting bracket 2).

[0041] The mounting bracket 2 forms a bracket structure which, in top view, is U-shaped. The "U" is formed by a transverse support 7 extending along the shaft wall 12 on the door side and two lateral supports 8 , 9 which protrude from the transverse support into the shaft space.

[0042] 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 a vertical support wall section 13, which can be arranged at the end of the floor delimited by the elevator shaft. The support wall section 13 forms a stop towards the door-side shaft wall and can terminate the transverse support 7 towards the elevator shaft. The support wall section 13 extends significantly in the horizontal direction between the lateral supports 8 and 9. When the mounting bracket 2 is correctly fastened to the floor, the fold or support wall section 13 preferably protrudes vertically downwards, so that the minimum distance between the guide rail that can be fastened to the mounting bracket 2 and the floor can be maintained by means of the fold.

[0043] The transverse carrier 7 has a floor fixing section 15, which is flat on the horizontal plane of the floor plate 11 and is fixed to or on the floor plate, so that the transverse carrier 7 is basically completely arranged within the floor plate 11. Therefore, basically only the lateral carriers 8 and 9 are arranged in the shaft space. Each of the lateral carriers 8 and 9 has a rail fixing section 14 extending parallel to the shaft wall 12 on the door side, and the rail fixing section has at least one assembly opening 18 for fixing the guide rail 3 shown in a schematic manner. The guide rail 3 is configured as a T-shaped rail profile, for example. Of course, rail profiles of other shapes can also be fixed on the mounting bracket 2. The special end-side connection of the guide rail 3 on the mounting bracket 2 is particularly suitable for the guide rail 3 designed as a hollow rail.

[0044] Figure 5The structural details of another variant of the mounting bracket 2 for mounting at the shaft door opening of the elevator system 1 are shown. The mounting bracket 2 with the transverse carrier 7 and the two lateral carriers 8, 9 forms a U-shaped bracket structure. The transverse carrier 7 extends in a first direction, which is defined by the shaft wall on the door side when the 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 perpendicularly to the first direction. The transverse carrier 7 has a floor fixing section 15, which can be fixed on the horizontal plane of the floor 11, so that the transverse carrier 7 can be arranged substantially completely within the floor 11. Therefore, 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, arranged on the free end of the lateral carrier, with two mounting openings 18. The two mounting openings 18 are used to fix the guide rails (not shown). Instead of the two mounting openings 18 shown as an example, of course, only one mounting opening 18 or even more than two mounting openings are also conceivable for each rail fastening section 14. The at least one mounting opening 18 is designed as an elongated hole, which has a favorable effect on the ease of assembly. Fastening screws or fastening pins for fastening the guide rail can be accommodated in the elongated hole.

[0045] The lateral supports 8, 9 and the transverse support 7 are each designed as a rigid curved part made of a metal sheet (e.g., a steel sheet). However, instead of a multi-piece structure, the mounting bracket 2 can also be designed in a single piece and made of a single or common sheet cut section. The transverse support 7 has a vertical support wall section 13 connected to the floor fixing section 15 and formed by a folded portion as a stop for the shaft wall on the door side. The corresponding lateral supports 8, 9 have a horizontal lintel section 17 and a vertical lintel section 16. Here, the description of the orientation (horizontal and vertical) refers to the situation after assembly. The vertical lintel section 16 is connected to the horizontal lintel section 17 in one piece by a folded portion. The two lintel sections 16 and 17 extend from the transverse support 7 to the guide rail. The support wall section 13 is arranged at the front end of the lateral supports 8, 9. The rail fastening section 14 now adjoins the horizontal web section 17 at a right angle and is connected to the horizontal web section 17 via a fold.

[0046] In particular, you can also Figure 6 As can be seen in FIG. 1 , the floor fixing section 15 forms a plate-shaped support structure which extends over the entire length of the transverse carrier 7 (length when viewed with respect to the aforementioned first direction). The floor fixing section 15 is designed to be large enough to be placed on a horizontal floor. It may be advantageous if the floor fixing section 15 acts on a horizontal surface on the floor which is at least as large as the total cross section of the guide rail.
