Description

[0001] ELEVATOR SHAFT AND METHOD FOR FASTENING AN ELEVATOR ELEMENT IN AN ELEVATOR SHAFT

[0002] The present invention relates to an elevator shaft and a method for fastening an elevator element in an elevator shaft. In particular, the invention relates to an elevator shaft with a fastening arrangement and a method for fire-safe fastening of the elevator element in the elevator shaft.

[0003] An elevator system is used to transport people and / or objects from one floor to another in a building. Such an elevator system may, for example, comprise an elevator car and an elevator shaft. The elevator car is designed to accommodate one or more people and / or loads and is movable within the elevator shaft, for example, vertically and / or from one floor to another.

[0004] The elevator shaft for an elevator system, for example, may have wooden walls that each define an interior space of the elevator shaft in a lateral and / or horizontal direction. In such a case, the elevator shaft may also be referred to as a wooden shaft.

[0005] The elevator shaft can optionally be composed of individual elevator shaft modules that can be arranged one above the other and fastened to one another and which, in this state, together form the elevator shaft.

[0006] For fire safety reasons, most countries require these wooden walls to be fire-safely separated from the interior space by means of fire-resistant cladding, which defines the interior of the elevator shaft laterally and / or horizontally. However, fire safety regulations may vary in detail from country to country. For example, the fire-resistant cladding can be created using several plasterboard and / or gypsum fiberboard panels applied to the wooden walls.

[0007] While fire-resistant cladding ensures fire protection, it presents challenges when it comes to securing one or more elevator elements to the inside of the elevator shaft. In particular, the fire-resistant cladding may only be minimally adapted and / or modified for the attachment of elevator elements. Such elevator elements may, for example, be one or more brackets or angles, which in turn can be used to secure other elevator components, such as one or more guide rails in the elevator shaft. For example, the brackets or angles can be attached directly to the fire-resistant cladding, for example, by screwing them onto it. However, this is not permitted in all countries.Furthermore, this transfers a significant portion of the weight to be borne by the respective lift element to the fire-resistant cladding instead of the wooden wall, even though the fire-resistant cladding is generally not designed to support such a weight. Alternatively, it is known to remove large areas of the fire-resistant cladding and attach the lift element to be secured directly or indirectly to the exposed wooden wall, for example, by screwing. However, this requires additional work for a fitter, and depending on country-specific fire safety regulations, acceptance by a fire safety expert may be required. In the worst case, the expert may not approve the corresponding fastening arrangement, and it may have to be removed again.

[0008] US 1896900 A1 and CN 113307123 A describe fastening arrangements for fastening an elevator element in an elevator shaft with a threaded insert and a matching screw element.

[0009] There may therefore be a need for an elevator shaft with an improved fastening arrangement and / or an improved method for fastening an elevator element in an elevator shaft, each of which contributes to ensuring that the fire-resistant cladding is subjected to as little weight as possible by the elevator element, is as independent as possible of the compressive strength of the fire-resistant cladding, requires as little, ideally minimal, installation effort for a qualified installer, and can be used without additional approval by a qualified fire protection expert. Furthermore, there may be a need for the elevator system that includes the elevator shaft with the fastening arrangement.

[0010] These needs can be met by the subject matter of the independent claims. Advantageous embodiments are set forth in the dependent claims, the following description, and the accompanying figures.

[0011] One aspect of the invention relates to an elevator shaft of an elevator system. The elevator shaft comprises: four wooden walls, which are mechanically connected to one another and arranged relative to one another in such a way that they laterally delimit an interior space of the elevator shaft for (possibly later) accommodating an elevator car of the elevator system; the fire protection cladding, which is arranged on the inner sides of the wooden walls and thus on an inner side of the elevator shaft on the wooden wall; and at least one elevator element, which is fastened to one of the wooden walls by means of a fastening arrangement described in the following paragraph.

[0012] The fastening arrangement mentioned in the previous paragraph comprises: a wall recess that extends through the fire-resistant cladding and into the wooden wall and has both a wooden recess in the wooden wall and a cladding recess in the fire-resistant cladding; a threaded insert that is arranged both in the wooden recess and in the cladding recess and thus in the wall recess and that has a thread; and a screw element that matches the thread and is screwed to the thread, wherein the elevator element is arranged between the threaded insert and the screw element and is mechanically coupled to the wooden wall by means of the screw element and the threaded insert. A further aspect of the invention relates to a method for fastening the elevator element in the elevator shaft.The elevator shaft has the wooden wall and the fire-resistant cladding arranged on the wooden wall on the inside of the elevator shaft. The method comprises: forming a wall recess such that it extends through the fire-resistant cladding and into the wooden wall and has both a wooden recess of the wooden wall and a cladding recess of the fire-resistant cladding; arranging the threaded insert, which has the thread, in both the wooden recess and the cladding recess and thus in the wall recess; arranging the elevator element between the threaded insert and the screw element that matches the thread; and screwing the screw element to the thread, such that the elevator element is fastened to the wooden wall by means of the screw element and the threaded insert.

[0013] It should be noted that, in order to provide a concise description and to avoid unnecessary repetition, features, embodiments, advantages and / or technical effects of the present invention are described below in part exclusively with reference to one of the aspects, and that these features, embodiments, advantages or technical effects can be readily transferred to another of the aspects.

[0014] The fastening arrangement, in particular the threaded insert of the fastening arrangement, which is arranged in the wall recess as described, ensures that a large portion of the weight exerted on the lift element is transferred directly to the wooden wall, so that the fire protection cladding is subjected to as little weight as possible from the lift element. This largely eliminates the need for the fire protection cladding to compressive strength. Furthermore, the wall recess can be formed relatively easily, for example, by drilling, and the threaded insert can be arranged relatively easily in the wall recess, so that the installation effort for a qualified fitter is as low as possible, ideally minimal.Furthermore, the fastening arrangement can generally be used without additional approval by a fire protection expert, at least as long as the diameter of the wall cutout, which also corresponds to the diameter of a corresponding cladding cutout in the fire protection cladding, does not exceed the country-specific requirements for cutouts in fire protection cladding. For example, a single cladding cutout with a diameter of approximately 10 mm or less is not critical in most countries and can be incorporated into the fire protection cladding without the necessary approval.

[0015] The elevator shaft can, for example, have four walls arranged at right angles to one another, which laterally delimit an interior space for laterally accommodating an elevator car of the elevator system, and which each have such a wooden wall. In particular, the walls can consist of wooden walls. Optionally, the fire-resistant cladding can also be considered part of the walls, so that in this case the fire-resistant cladding laterally delimits the interior space. Otherwise, the fire-resistant cladding can be considered to be arranged in the interior space. Thus, the elevator shaft can have four wooden walls, each of these wooden walls can be lined with a corresponding fire-resistant cladding. The fastening arrangement can be used for the fire-safe fastening of one or more of the elevator elements to any of the wooden walls.

[0016] The fire-resistant cladding can, for example, be applied over the entire surface of the corresponding wooden wall. In particular, the fire-resistant cladding can be applied to the corresponding wooden wall in such a way that no part of the wooden wall is exposed to the interior of the elevator shaft.

[0017] The elevator element can be any element of the elevator system that must be attached to the inside of the elevator shaft. For example, the elevator element can be a connecting element by means of which other components of the elevator system can be attached to the inside of the elevator shaft. For example, the elevator element can be a bracket or a bracket by means of which a guide rail or a shaft door of the elevator system is coupled to the elevator shaft.

[0018] The wall recess can have a diameter of, for example, 5 mm to 50 mm, for example 7 mm to 25 mm, for example approximately or exactly 10 mm. The fact that the wall recess extends through the fire protection cladding and into the wooden wall can mean, for example, that the wooden wall has a wooden recess and the fire protection cladding has the cladding recess, that the wooden recess and the cladding recess overlap one another, for example, are congruent and flush with one another, and that the wall recess has both the wooden recess and the cladding recess. The fact that the threaded insert is arranged in the wall recess can mean that the threaded insert is arranged in both the wooden recess and the cladding recess.

[0019] The threaded insert can also be referred to as a sleeve or threaded sleeve. Optionally, a washer can be placed between the elevator element and the threaded insert.

[0020] The lateral direction is perpendicular to a vertical direction. The vertical direction refers to the orientation of the elevator shaft in which an elevator car can be moved vertically. The lateral direction is thus parallel to a horizontal plane.

[0021] According to one embodiment, the threaded insert of the fastening arrangement is fitted into the wall recess. This can contribute to the threaded insert being secured particularly reliably and resiliently in the wall recess, to the threaded insert being particularly easy to insert into the wall recess, and / or to the weight transmitted by the elevator element being particularly well dissipated into the wooden wall. In this context, it can be advantageous, for example, to form the wooden recess with a press fit to the threaded insert and to form the cladding recess with a clearance fit to the threaded insert, since the threaded insert is then essentially secured in the wooden recess and a small, in particular minimal, gap remains between the threaded insert and the cladding recess, and the threaded insert transmits little to no force to the fire protection cladding.The fact that the threaded insert is fitted into the recess can mean, for example, that the recess is designed with a clearance fit or an interference fit with the threaded insert. For example, an outer diameter of the threaded insert can match an inner diameter of the recess, i.e., be slightly larger, slightly smaller, or exactly the same.

[0022] According to one embodiment, the threaded insert of the fastening arrangement has an insert body recess. The thread of the threaded insert is an internal thread formed in an insert body recess of the threaded insert, and the screw element is a screw that is screwed into the internal thread. This allows for easy provision of the thread for fastening the screw element. The screw can be a hexagon screw, for example. The insert body recess can, for example, extend through the entire threaded insert.

[0023] According to one embodiment, the threaded insert of the fastening arrangement comprises a threaded rod having a first external thread and projecting into an interior of the elevator shaft. The first external thread is the thread of the threaded insert, and the screw element is a screw nut screwed onto the first external thread. This enables easy provision of the thread for fastening the screw element. The threaded insert can, for example, comprise an insert body and the threaded rod, wherein the threaded rod is fastened to the insert body. If the threaded insert has the insert body recess instead of the threaded rod, the threaded insert can comprise only the insert body in which the internal thread is formed. In both cases, the insert body can extend over the entire length of the wall recess.

[0024] If the washer is arranged between the elevator element and the threaded insert, in the case of the insert body recess, the washer can be arranged, for example, between an end of the insert body facing the interior and the elevator element, with the screw extending through the washer. In the case of the threaded insert with the threaded rod, the washer can be arranged, for example, between an end of the insert body facing the interior and the elevator element, with the threaded rod extending through the washer.

[0025] According to one embodiment, the threaded insert of the fastening arrangement has a second external thread, by means of which the threaded insert is screwed into the wall recess. This can contribute to a secure and reliable fastening of the threaded insert in the wall recess. The second external thread can, for example, be designed such that it is arranged exclusively in the area of ​​the wooden wall and not in the area of ​​the fire protection cladding, so that the threaded insert is essentially fastened to the wooden wall. Alternatively or additionally, the threaded insert can be fixed in the wall recess by means of a press fit. Alternatively or additionally, the threaded insert can be glued into the wall recess.

[0026] According to one embodiment, the threaded insert of the fastening assembly is designed and arranged such that the threaded insert protrudes beyond the fire protection cladding into the interior. This can help ensure that as little force as possible, ideally no force at all, is transferred from the elevator element to the fire protection cladding. An end of the insert body facing away from the wooden wall can protrude, for example, 1 mm to 10 mm, for example, 2 mm to 8 mm, or 5 mm, beyond the fire protection cladding into the interior of the elevator shaft.

[0027] According to one embodiment, a fire protection element is arranged between the fire protection cladding and the elevator element. This element has a fire protection element recess through which the threaded insert extends. This can contribute to a high level of fire protection in the area of ​​the fastening arrangement, particularly in the area of ​​the cladding recess. The fact that the threaded insert extends through the fire protection element recess can, for example, mean that the insert body extends through the fire protection element recess.

[0028] According to one embodiment, the wall recess is formed with a predetermined fit to the threaded insert. The predetermined fit can be, for example, a clearance fit and / or a press fit. Alternatively or additionally, the threaded insert of the fastening arrangement can have the second external thread, by means of which the threaded insert is screwed into the wall recess when the threaded insert is arranged in the wall recess.

[0029] According to one embodiment, the thread of the threaded insert of the fastening arrangement is the internal thread formed in the insert body recess of the threaded insert, and the screw element is the screw that is screwed into the internal thread when screwing the screw element.

[0030] According to one embodiment, the threaded insert of the fastening arrangement comprises the threaded rod which has the first external thread and which projects into the interior of the elevator shaft, the thread of the threaded insert is the first external thread, and the screw element is the screw nut which is screwed onto the first external thread when the screw element is screwed.

[0031] According to one embodiment, the threaded insert of the fastening arrangement is designed and arranged such that the threaded insert protrudes beyond the fire protection cladding into the interior space, and the fire protection element, which has the fire protection element recess, is arranged between the fire protection cladding and the elevator element such that the threaded insert extends through the fire protection element recess. Embodiments of the invention are described below with reference to the accompanying drawings. Neither the description nor the drawings are to be understood as limiting the invention.

[0032] Fig. 1 shows an elevator system with an elevator shaft according to an embodiment of the present invention.

[0033] Fig. 2 shows an embodiment of a fastening arrangement.

[0034] Fig. 3 shows an exemplary embodiment of a fastening arrangement.

[0035] Fig. 4 shows a flow diagram of an embodiment of a method for fastening an elevator element in an elevator shaft module and thus in an elevator shaft of the elevator system according to Figure 1.

[0036] The drawings are purely schematic and not to scale. Identical reference symbols in different drawings indicate identical or equivalent features.

[0037] Fig. 1 shows an elevator system 1 according to an embodiment of the present invention. The elevator system 1 comprises an elevator car 3, an elevator shaft 5, a counterweight 7, a suspension element 9, a drive motor 11, a traction sheave 13, a brake 15, and an elevator control system 17.

[0038] The elevator shaft 5 is arranged in a building and extends over several floors of the building. In this exemplary embodiment, the elevator shaft 5 is of modular construction and has a plurality of elevator shaft modules 20 arranged one above the other, which are fastened to one another and which together form the elevator shaft 5. An interior of the elevator shaft 5, in which the elevator car 3 is arranged, is formed from interior spaces 21 of the elevator shaft modules 20. The elevator shaft modules 20 each have four wooden walls 22, which are mechanically connected to one another such that the interior spaces 21 of the elevator shaft modules 20 are formed at right angles. The wooden walls 22 are arranged relative to one another such that they each laterally delimit the corresponding interior space 21 of the corresponding elevator shaft module 20 for accommodating the elevator car 3.

[0039] It is not necessary for the elevator shaft to be composed of multiple elevator shaft modules. The statements regarding the wooden walls, fire protection cladding, and fastening arrangements 31 for securing an elevator element of the elevator shaft modules 5 apply analogously to wooden walls, fire protection cladding, and fastening arrangements 31 for securing an elevator element of an elevator shaft not composed of elevator shaft modules.

[0040] A fire protection cladding 24 is attached to the wooden walls 22, which separates the wooden walls 22 from the interior spaces 21, so that a fire in the interior of the elevator shaft 5 cannot penetrate, or can only penetrate to a limited extent, the wooden walls 22. The fire protection cladding 24 can, for example, be applied over the entire surface of the corresponding wooden wall 22. In particular, the fire protection cladding 24 can be applied to the corresponding wooden wall 22 in such a way that no area of ​​the wooden wall 22 is exposed to the interior space 21 of the corresponding elevator shaft module 20.

[0041] The elevator car 3 can be moved within the elevator shaft 5, particularly in the vertical direction. The elevator car 3 is suitable for accommodating one or more people and / or loads and for transporting the people or loads from one floor to another of the floors of the building. The vertical direction refers to the intended arrangement of the elevator shaft modules 20 shown in Figure 1, in which the interior of the elevator shaft 5 extends over several of the elevator shaft modules 20 in the vertical direction for the vertical movement of the elevator car 3. In contrast, a lateral direction is perpendicular to the vertical direction. The lateral direction is thus parallel to a horizontal line. For example, the interior spaces 21 of the elevator shaft modules 20 are delimited in the lateral direction by the wooden walls 22 and the fire protection cladding 24 arranged thereon.

[0042] The drive machine 11 is mechanically coupled to the elevator car 3 via the support means 9. The support means 9 serves to hold the elevator car and can, for example, comprise a rope, a wire, a belt, and / or a band. The drive machine 11 is designed to vertically displace the elevator car 3 in the elevator shaft 5 by means of the support means 9. The support means 9 can extend over the traction sheave 13 and be driven by the drive machine 11. Furthermore, the counterweight 7 can be held by the support means 9 and coupled to the elevator car 3.

[0043] A brake 15 can be provided on the drive machine 11. The brake 15 can be designed to brake the rotation of the traction sheave 13 of the drive machine 11 or to prevent the traction sheave 13 from rotating, thus preventing the elevator car 3 from moving. The brake 15 and the drive machine 11 can be controlled by an elevator control system 17. The elevator control system 17 can include a current converter 19, for example, an inverter, which is electrically coupled to the drive machine 11 to supply the drive machine 11 with power.

[0044] During this displacement in the elevator shaft 5, the elevator car 3 can be guided via guide shoes (not shown) and / or guide rollers (not shown) along at least one guide rail 28 anchored in the elevator shaft 5. This anchoring represents an example of an elevator element 26 that is fastened to an inner side of the elevator shaft 5 by means of one or more fastening arrangements (see Figures 2 and 3) and that is designed to mechanically couple one or more components of the elevator system 1, for example the guide rail 28, in the elevator shaft 5. One or more corresponding elevator elements 26 can alternatively or additionally be arranged to fasten other components of the elevator system 1. The elevator element 26 can, for example, be a bracket or an angle bracket.In general, the elevator element 26 can be any element of the elevator system 1 that needs to be attached to the inside of one or more of the elevator shaft modules 20. Furthermore, the elevator element 26 can generally be used to attach any component of the elevator system 1 that needs to be mechanically coupled to one or more of the elevator shaft modules 20.

[0045] Fig. 2 shows an embodiment of a fastening arrangement 31. The fastening arrangement 31 serves to fasten the elevator element(s) 26 in the corresponding elevator shaft module 20. The fastening arrangement 31 can be used in particular for the fire-safe fastening of one or more of the elevator elements 26 to any one of the wooden walls 22. The fastening arrangement 31 has a wall recess 48, a threaded insert 34, and a screw element.

[0046] The wall recess 48 extends through the fire-resistant cladding 24 and into the wooden wall 22. The wall recess 48 can thus have a wooden recess 50 in the wooden wall 22 and a cladding recess 52 in the fire-resistant cladding 24. For example, the wooden recess 50 and the cladding recess 52 overlap one another and are congruent and flush with one another. The wall recess 48 can have a diameter D of, for example, 5 mm to 50 mm, for example, 7 mm to 25 mm, for example, approximately or exactly 10 mm.

[0047] The threaded insert 34 is arranged in the wall recess 48 and has a thread. The threaded insert 34 can have an insert body 44, which can have an insert body recess 46. The insert body 44 can extend over the entire length of the wall recess 48. The threaded insert 34 can, for example, be arranged in the wood recess 50 and in the panel recess 52. The threaded insert 34 can be fitted into the wall recess 48. In this context, it can be advantageous to form the wood recess 22 with a press fit to the threaded insert 34 and to form the panel recess 52 with a clearance fit to the threaded insert 34.

[0048] For example, an outer diameter of the threaded insert 34 can match an inner diameter of the wall recess 48, i.e., for example, be minimally larger than or exactly the same size as an inner diameter of the wood recess 22 and / or be minimally smaller than or exactly the same size as the cladding recess 52.

[0049] The thread of the threaded insert 34 can, for example, be an internal thread 36 formed in an insert body recess 46 of the threaded insert 34. Alternatively, the thread of the threaded insert 34 can be a threaded rod 54 having a first external thread 56 (see Figure 3). The threaded insert 34 can also be referred to as a sleeve or threaded sleeve. Optionally, a washer (not shown) can be arranged between the elevator element 26 and the threaded insert.

[0050] The screw element fits the thread and is screwed to the thread, with the lifting element 26 being arranged between the threaded insert 34 and the screw element and being mechanically coupled to the wooden wall 22 by means of the screw element and the threaded insert 34. The screw element can be, for example, a screw 32 having a screw thread 38 and screwed into the internal thread 36 with its screw thread 38. Alternatively, the screw element can be a screw nut 58 screwed onto the threaded rod 54 (see Figure 3). The screw 32 can be, for example, a hexagon screw.

[0051] Optionally, the threaded insert 34 can have a second external thread 42, by means of which the threaded insert 34 is screwed into the wall recess 48. The second external thread 42 can, for example, be designed such that it is arranged exclusively in the area of ​​the wooden wall 22 and not in the area of ​​the fire protection cladding 24, so that the threaded insert 34 is essentially fastened to the wooden wall 22. Alternatively or additionally, the threaded insert 34 can be fixed in the wall recess 48 by means of a press fit. Alternatively or additionally, the threaded insert 34 can be glued into the wall recess 48.

[0052] Optionally, the threaded insert 34 can be designed and arranged such that the threaded insert 34 protrudes beyond the fire protection cladding 24 into the corresponding interior space 21. For example, an end of the insert body 44 facing away from the wooden wall 22 can have a distance H from the fire protection cladding 24 of, for example, 1 mm to 10 mm, for example 2 mm to 8 mm, for example 5 mm. In this case, a fire protection element 30 can be arranged between the fire protection cladding 24 and the elevator element 26, which fire protection element has a fire protection element recess 33 through which the threaded insert 34 extends. For example, the insert body 34 can extend through the fire protection element recess 33.

[0053] If the washer is arranged between the lifting element 26 and the threaded insert 34, the washer can be arranged, for example, between an end of the insert body 44 facing the corresponding interior space 21 and the lifting element 26, wherein the screw 32 can extend through the washer.

[0054] Fig. 3 shows an embodiment of a fastening arrangement 31. The fastening arrangement 31 shown in Figure 3 can largely correspond to the fastening arrangement 31 shown in Figure 2. Therefore, in the following, we will only discuss the features of the fastening arrangement 31 shown in Figure 3 with respect to which the fastening arrangement 31 shown in Figure 3 differs from the fastening arrangement 31 shown in Figure 2.

[0055] The threaded insert 34 can, for example, have the insert body 44 and the threaded rod 56. The threaded rod 56 can be fastened to the insert body 44 or formed integrally therewith. The threaded rod 56 can have the first external thread 56 as the thread of the threaded insert 34. The threaded rod 56 can protrude into the interior 21 of the corresponding elevator shaft module 20. In this case, the screw element of the fastening arrangement 31 can be the screw nut 58, which is screwed onto the first external thread 56. If the washer is arranged between the elevator element 26 and the threaded insert 34, the washer can, for example, be arranged between the end of the insert body 44 facing the corresponding interior 21 and the elevator element 26, wherein the threaded rod 56 extends through the washer.

[0056] Fig. 4 shows a flowchart of an exemplary embodiment of a method for fastening an elevator element in an elevator shaft module of the elevator system according to Figure 1. The method serves to fasten the elevator element 26 in one of the elevator shaft modules 20.

[0057] In a step S2, the wall recess 48 can be formed such that it extends through the fire protection cladding 24 and into the wooden wall 22, for example, as explained above. The wall recess 48 can, for example, be drilled from the corresponding interior space 21 into the fire protection cladding 24 and the wooden wall 22.

[0058] In a step S4, the threaded insert 34, which has the thread, can be arranged in the wall recess 48. As explained above, the threaded insert 34 can be inserted, inserted, fitted, pressed, glued, and / or screwed into the wall recess 48.

[0059] In a step S6, the elevator element 26 can be arranged between the threaded insert 34 and the screw element that fits the thread.

[0060] In a step S8, the screw element, for example the screw 32 or the screw nut 58, can be screwed to the corresponding thread, for example the internal thread 36 in the insert body recess 46 or the first external thread 56 of the threaded rod 54, so that the elevator element 26 is fastened to the wooden wall 22 by means of the screw element and the threaded insert 34, in particular by means of the corresponding thread.

[0061] The invention is not limited to the exemplary embodiments explained above. For example, the elevator system 1 can be any elevator system. For example, the elevator system 1 can be designed as a double-deck elevator. Alternatively or additionally, the elevator system 1 can have two or more of the elevator cars 3. Furthermore, the elevator system 1 can have more or fewer of the elevator shaft modules 20. Furthermore, the elevator system 1 can have more or fewer of the fastening arrangements. Furthermore, one or more of the fastening arrangements can be used to fasten components of the elevator system 1 other than the guide rail(s) 28 in the elevator shaft 5 by means of the elevator elements 26. Furthermore, the elevator elements 26 can have a shape that deviates from the clamp and / or angle shape.For example, one or more of the elevator elements 26, which are configured to couple the corresponding component of the elevator system 1 to the corresponding elevator shaft module 20, may have an elongated, rod-like and / or rail-like shape.

[0062] Finally, it should be noted that terms such as "comprising," "comprising," "including," "having," etc., do not exclude other elements or steps, and indefinite articles such as "a" or "an" do not exclude a plurality. Furthermore, it should be noted that features or steps described with reference to one of the above embodiments may also be used in combination with features or steps described with reference to other of the above embodiments. Reference signs in the claims are not to be understood as limiting.
