Description

Technical field

[0001] The present invention relates to a positive-locking / force-locking fastening system for at least one load-bearing system component of an elevator system, in particular for rail system components, comprising a plurality of positive-locking / force-locking fastening means for fastening the at least one load-bearing system component to at least two fastening points or on / in at least two fastening axes. Furthermore, the present invention relates to a corresponding fastening method, in particular comprising at least one at least partially automated handling step. Finally, the present invention also relates to the use of counter-measures acting jointly for several fastening means for fastening load-bearing system components, in particular rail system components in elevator systems, especially where access is only possible from one side in the axial direction of one or more fastening axes.In particular, the invention relates to a device and a method according to the preamble of the respective independent claim. Technical background

[0002] Some system components of extension systems are subject to special requirements regarding relative positional accuracy, positional tolerance, safety, accessibility, force transmission, and / or the like. This applies, for example, to load-bearing rail system components. Particularly in very long extension systems with large travel distances, it is important to be able to fasten the individual rail system components securely, while also allowing for a certain degree of positioning tolerance during assembly, especially with regard to their relative position to the adjacent rail system component (e.g., in the case of guide rails or running rails arranged in a row).

[0003] According to current technology, load-bearing rail system components are fastened using screw connections. Depending on the fastening point, accessibility may be limited, necessitating the design of recesses to ensure accessibility at numerous fastening points. This can negatively impact the design effort, material usage, and / or assembly effort. Based on the current state of the art, there is a clear need for improved fastening systems. In particular, there is interest in improved fastening methods and the associated assembly steps. Finally, there is also significant interest in improved fastening systems and procedures, especially with regard to ergonomics and labor efficiency during elevator installation. Description - Technical Solution

[0004] Given this situation, the present task is to provide a fastening system or method for load-bearing system components of extension mechanisms, thereby ensuring an advantageous synergy, particularly with regard to the requirements of positional accuracy, tolerance, safety, accessibility, and design variability. It is also a task to design such a fastening system in such a way that the fastening method implemented with it can be carried out in a particularly safe and / or ergonomic manner.

[0005] This problem is solved by a positive-locking / force-locking fastening system according to claim 1 and by a method according to the respective dependent method claim. Advantageous embodiments of the invention are explained in the respective dependent claims. The features of the exemplary embodiments described below can be combined with one another unless explicitly stated otherwise.

[0006] A form-fit / force-fit fastening system is provided for at least one load-bearing system component of a lift system, comprising a plurality of form-fit / force-fit fastening means for fastening the at least one load-bearing system component to at least two fastening points or to / in at least two fastening axes; According to the invention, it is proposed that the form-fit / force-fit fastening system has a common countermeasure with a first force-fit / form-fit fastening interface for a first form-fit / force-fit fastening element and at least one further force-fit / form-fit fastening interface for a further form-fit / force-fit fastening element and is configured to counteract the first and the at least one further form-fit / force-fit fastening element against a relative movement at the common countermeasure when simultaneously engaging the corresponding force-fit / form-fit fastening interfaces and to create a form-fit / force-fit fastening (orTo ensure the connection) of the load-bearing system component, particularly when only one-sided and preferably only one-handed engagement of the respective form-fit / force-fit fastener is possible using only a single, preferably one-handed, fastening tool (i.e., without any counter-holding or counter-tool). This enables an advantageous synergy with regard to the requirements of positional accuracy, positional tolerance, safety, accessibility, and design variability.

[0007] Where the term "system component" is used in general in the present disclosure, it is to be understood synonymously as a load-bearing system component, in particular a rail system component, especially a guide rail for at least one elevator car that can be moved along one / the respective path of movement.

[0008] Insofar as the present disclosure refers to counter-measures, these are to be understood synonymously as a correspondingly effective measure for holding a nut or similar counterpart (or coupling partner or paired connecting partner) against a screw or the like, in particular a fastening means to be fastened by relative rotation.

[0009] Where the present disclosure refers to screws (connections) or bolts (connections), these are to be understood synonymously as a correspondingly equivalent type of force-fit / form-fit fastening or connection.

[0010] Personalized terms, unless explicitly formulated in the neuter gender, may refer to all genders within the context of this disclosure. Any foreign-language expressions or abbreviations used here are standard industry terms and are familiar to those skilled in the art. Any synonymous German terms used / available may be indicated here in parentheses for the sake of completeness, or vice versa.

[0011] The present invention relates in particular to at least one force-fit / form-fit (screw) connection component of the type or with the functionality of nuts, with a counterholding function. The present invention can be used in particular for force-fit / form-fit (screw) connections in elevator systems, especially in elevator systems having guide rails for at least one elevator car that can be moved along one or more of the respective path of travel. In particular, the present invention relates to the method of mounting and permanently fastening the tracks or rails (guide rail(s) and their suspension) of elevator systems, especially to built-in guide rail components where high dynamic loads are observed or expected. The proper functioning of such rail components and their operation must be regularly observed or monitored.This monitoring obligation includes, in particular, the regular inspection of commonly used (bolted) connections, especially to ensure that the preload of the bolts or fasteners does not decrease noticeably. In many types of elevator systems, the (bolted) connections must be / remain accessible, especially those subjected to high dynamic loads. Furthermore, a simple method of assembly, particularly of the rail components, is preferred in many elevator systems, especially since the rail fastening may be achieved within a certain tolerance range, particularly by using elongated holes. However, in some elevator system configurations, (bolted) connections or fasteners are at least partially concealed.not accessible at all or only with great difficulty, so that a comparatively high level of design effort is required to be able to install standard and easily calculated or designed (screw) connections or fasteners in an accessible manner.

[0012] According to the state of the art, in some elevator suspension configurations, recesses are required as part of the design, particularly to allow for counter-tightening of the screw(s) when tightening a corresponding nut, or vice versa. In some elevator suspension or track system configurations, the screw heads are no longer accessible after the guide units are installed; that is, counter-tightening the screws while simultaneously checking the bolt preload is not possible or only with great difficulty. In some elevator suspension system configurations, it is also not possible to incorporate a thread into the corresponding load-bearing components, particularly due to the need to tolerate relative movements or positional tolerances of the connected or bolted components relative to the bolts themselves, especially due to elongated holes incorporated into the respective component (to allow for alignment in different directions).Furthermore, in some elevator suspension system configurations, the rail brackets may have elongated holes and therefore need to be held or aligned during tightening, which places certain demands on the simplest possible installation method. While access to the fixing points can be ensured relatively easily in some elevator suspension system configurations, it still seems necessary that no screw components or fasteners need to be held manually during the tightening or fastening process, or that accessibility requirements for fastening are kept to a minimum, particularly with regard to ergonomic advantages and to facilitate the installation process.

[0013] Based on the state of the art, the person skilled in the art may be encouraged to consider improved screw systems or other (alternative) fastening points or a different design, in particular to avoid the need for access recesses.

[0014] In contrast, the concept of the present invention is based in particular on the following findings: Each nut typically used in standard applications can be replaced by a common locking element, particularly in the form of, for example, a cuboid rod or a correspondingly solid block, with at least two force-fit / form-fit fastening interfaces (e.g., internal threads) for at least two force-fit / form-fit connections or fastening points. The common locking element connects, combines, or couples at least two or more (screw) bolts or similar fastening elements, in particular (screw) bolts positioned side by side, which act in different (elongated) holes of the system component to be fastened. The screw connections or fastening elements can still be positioned independently relative to the at least one system component.This can also ensure the desired alignment or fine-tuning of differently oriented elongated holes. The bolt connections or fasteners are advantageously not independently or relative to each other, as they are connected by a common counter-measure (e.g., rod), or as the common counter-measure dictates the relative position of the at least two fasteners relative to each other.

[0015] The connection of the screws or bolts by the common locking element essentially ensures the function of holding and locking during tightening. Furthermore, the respective fastener can also be secured against loosening by means of the common locking element. Access is only required on one side of the respective fastening point, and only one fastening tool is needed, or (in the case of at least partially manual assembly) only one hand is required.

[0016] Thus, the fasteners are positioned relative to each other by the common counter-element, and as long as they are not fixed in a load-bearing manner, at least one system component can still be positioned or aligned relatively (especially within the degrees of freedom defined by elongated holes). This also ensures the desired relative alignment of the fastening system described here in the context of differently oriented (elevator system-specific) elongated holes. The bolt connections are therefore not independently movable / positionable, as they are predefined and coupled to each other when engaged by the common counter-element (e.g., rod). In this respect, the common counter-element defines a unique positional relationship between at least two fasteners, which can facilitate (at least partially manual) handling, especially during a pre-assembly process.The fasteners remain independent of each other, allowing their fastening / contact positions (e.g., bolted connections) to be varied by moving at least one system component within differently oriented elongated holes. The connection of the bolts by the common locking element essentially serves to hold and lock them during tightening, but can also ensure particularly uniform contact pressure. Optionally, intermediate washers can replicate the contact or holding behavior (friction, pressure distribution) of screw heads or nuts. The fastening system requires access from only one side, and only one fastening tool and one hand are needed (simultaneously).

[0017] The present invention offers, in particular, the following technical advantages: The self-locking function achieved by means of the common locking element allows access from only one side, for example, when the other side is blocked or difficult to access, or when a design recess cannot or should not be provided there. Furthermore, thanks to the common locking element, only one hand or one fastening tool is required to tighten a screw connection or to create a respective fastening point, which can also lead to improved (working) ergonomics.

[0018] Thanks to the present invention, a specialist or fitter may in particular perform the following steps, which can at least be partially automated, in order to achieve a load-bearing, safety-relevant (rail) system components of elevator systems in accordance with specifications in a simple, elegant, ergonomic and labor-minimizing manner: Step S1 Inserting (pre-assembling) the common countermeasure during a pre-assembly process, in particular in such a way that the connection (especially by means of bolts or screws) to the system component is still prepared in a pre-assembled state, which allows relative movements for the purpose of adjusting a target relative position; Step S2 relative positioning of the at least one system component to be fastened by a relative movement of the corresponding system component, in particular by means of alignment tool(s), into the desired position, in particular within a respective degree of freedom defined by elongated holes; Step S3 involves properly fastening (load-bearing fixing of the position) the components by tightening the screw connection(s) with a fastening tool, in particular using only one hand (since holding a nut is no longer necessary).

[0019] It should be understood that after step S1, at least one of the fasteners can already be lightly attached (e.g., by hand-tightening a screw) before step S2 is carried out; in this respect, the sequence of the individual steps suggested here by the numbering should not be understood as restrictive.

[0020] It is understood that the fastening procedure described here may also include further steps, for example a step S4 concerning the application or at least checking of a predefined / predefinable torque around the respective fastening axis, in particular one-handed using a torque wrench or similar tool, whereby this step in particular may also be carried out at least partially automatically by a robot or similar assembly aid.

[0021] According to one embodiment, the respective force-fit / form-fit fastening interface comprises a thread, in particular an internal thread, preferably a through internal thread. This also facilitates the use of standard screw bolts as fasteners and can also simplify the (structural) design of the fastening. The thread can be an integral, one-piece component of the base body of the common locking element. It is understood that the respective thread can advantageously be designed to meet the high safety requirements in the elevator sector, e.g., with regard to load-bearing capacity, thread pitch, number of thread turns, self-locking function, and the like.

[0022] According to one embodiment, the common counter-measure has a preferably at least approximately flat contact surface designed for contact with, or in relation to, the corresponding system component of the elevator system, via which a predefined / predefinable fastening force applied by means of the positive / force-locking fasteners can be transferred to the system component. This also facilitates the application of a fastening force predefined / predefinable (in magnitude) by the fastening system, particularly as a function of predefined / predefinable tightening torques. Optionally, the contact surface can also have several annular protruding areas (projecting areas in the direction of the system component when used as intended), particularly to replicate the contact / holding behavior (friction, pressure distribution) of screw heads or...Nuts; alternatively or additionally, washers can be used to simulate the contact pressure of screw heads or nuts.

[0023] According to one embodiment, the common counter-measure has a cuboid-shaped base body. This provides a good compromise, particularly regarding material usage, achievable strength, and the type and method of coupling with the system component.

[0024] According to one embodiment, the common counter-element is made of solid material. This also provides particularly high robustness and resistance, thus improving the load-bearing properties of the fastening system.

[0025] It is understandable that, in the context of load-bearing system components of elevator systems, especially track system components, high fastening forces may be required, including, for example, a comparatively high tightening torque. The common counter-locking element can meet this requirement in a relatively simple manner, particularly by being made of a suitably resistant material, especially metal.

[0026] It is to be understood that the respective form-fit / force-fit fastening interface of the common countermeasure can be integrally designed on the common countermeasure, e.g. in the form of an integral internal thread, and / or can be at least partially inserted or installed in the common countermeasure, e.g. in the form of a threaded sleeve (e.g. also positively coupled against rotation) with a retaining edge against axial slippage.

[0027] It is understood that the common locking element can also perform an anti-rotation function, namely by indirectly securing one of the positive-locking fasteners by another positive-locking fastener, in particular by preventing relative rotation of the common locking element relative to one, more, or all positive-locking fasteners as soon as at least two positive-locking fasteners are engaged with the common locking element. This also facilitates the achievement of a high degree of safety based on a comparatively simple measure. In this respect, the common locking element can also fulfill a securing function by indirectly securing multiple positive-locking fasteners engaged with the common locking element.

[0028] According to one embodiment, the positive-locking / force-locking fastening system defines at least two fastening axes, along which, in the intended assembled state, at least one washer is arranged between the corresponding positive-locking / force-locking fastener and the common counter-force (or acting between them). A pairing with at least one washer also offers advantages, in particular, with regard to the definability of the manner of load application / distribution at the respective fastening point.

[0029] According to one embodiment, the common counter-measure defines a unique positional relationship between at least two fasteners. This allows, on the one hand, a comparatively simple design and calculation of loads / load distributions, particularly in the area of ​​the respective fastening points. On the other hand, the common counter-measure can be provided with a comparatively simple structure and a high degree of standardization. For example, the system component is fastened by means of a plurality of common counter-measures, each of which defines a unique positional relationship between the fasteners engaging in pairs in the respective common counter-measure relative to each other.

[0030] The aforementioned problem is also solved by an elevator system comprising at least one load-bearing system component, in particular a rail system component, which is fastened by means of a positive-locking / force-locking fastening system according to the present disclosure, especially also by using screw bolts as positive-locking / force-locking fasteners, each in combination with a solid common counter-measure with at least two internal threads for at least two screw bolts. This results in the aforementioned advantages, in particular with regard to a beneficial symbiosis, also ensured during installation / assembly, concerning the requirements of positional accuracy, positional tolerance, safety, accessibility, ergonomics, and manual handling.

[0031] The aforementioned problem is also solved by a method according to the corresponding subordinate method claim, namely by a method for fastening a system component of an elevator system by means of at least one form-fit / force-fit fastening system according to the present disclosure, comprising the following steps: Step S1 Inserting (pre-assembling) one / the respective common countermeasure in conjunction with at least two positive-locking / force-locking fasteners and the load-bearing system component, in particular such that the positive-locking / force-locking fasteners are brought into engagement with the common countermeasure one after the other, in particular stepwise more and more; Step S2 Positioning of the at least one system component to be fastened by relative movement, in particular by means of an alignment tool, in particular relative to at least one other (in particular already fastened) system component; Step S3 involves the proper fastening of at least one system component by tightening the positive-locking / force-locking fasteners against the common counter-tightening element (without an additional manual counter-handling operation), in particular using a one-handed fastening tool. This results in the aforementioned advantages, especially with regard to a particularly simple, efficient, safe, and ergonomic assembly / installation process.

[0032] It is understood that the steps described here can themselves be at least partially automated and / or can be linked to at least one at least partially automated handling step, e.g., concerning the system component itself. In this respect, the present technical teaching does not concern purely manual handling steps; the person skilled in the art will recognize how the present technical teaching can be implemented in the context of at least partially automated methods or processes, e.g., by an alignment and / or fastening tool operating at least partially automatically and / or being positioned at least partially automatically, and / or by the respective system component being moved and / or positioned at least partially automatically.

[0033] According to one embodiment, the respective force-fit / form-fit fastening interface is screwed into a thread. This provides a high degree of safety and may also facilitate a partially automated installation process.

[0034] According to one embodiment, the common counter-measure with a contact surface is pressed against the system component of the elevator system to be fastened, applying a predefined fastening force, particularly within a predefined area (especially on a surface predefined in size and geometry) around the respective fastening point. This also facilitates the application of a predefined fastening force within a predefined area around the respective fastening point, thus enabling a comparatively good standardization of the load application method.

[0035] According to one embodiment, at least one washer is inserted between each positive-locking / force-locking fastener and the common counter-fastener. This also allows for a customizable specification of a particular mode of interaction between each system component and the fastening system.

[0036] The aforementioned problem is also solved by using at least one positive-locking / force-locking fastening system according to the present disclosure for fastening a load-bearing rail system component of an elevator system without a manual counter-handling step, wherein at least two positive-locking / force-locking fasteners are jointly counter-locked by means of one / the respective common counter-means of the positive-locking / force-locking fastening system. This allows the aforementioned advantages to be realized.

[0037] The aforementioned problem is also solved by using at least one positive-locking / force-locking fastening system according to the present disclosure for fastening a load-bearing system component of an elevator system by means of one or the respective common counter-means of the positive-locking / force-locking fastening system for holding and locking at least two positive-locking / force-locking fasteners, at least one of which is guided in or through an elongated hole, particularly when access is only possible from one side in the axial direction of one or the fastening axis. This allows the aforementioned advantages to be realized. The holding function also applies, in particular, to a phase of an assembly process in which the at least one system component still needs to be positioned relative to other system components.

[0038] Summary: When fastening load-bearing system components of an elevator system, high demands are placed on safety and accessibility, especially for rail system components, and not least on a certain degree of positional tolerance. A positive-locking / force-locking fastening system is provided for at least one system component of an elevator system, comprising a plurality of positive-locking / force-locking fasteners for fastening the at least one system component to at least two fastening points or on / in at least two fastening axes;According to the invention, the form-fit / force-fit fastening system comprises a common counter-means with a first force-fit / form-fit fastening interface for a first form-fit / force-fit fastening element and at least one further force-fit / form-fit fastening interface for a further form-fit / force-fit fastening element, and is configured to counteract the first and the at least one further form-fit / force-fit fastening element against relative movement at the common counter-means when the corresponding force-fit / form-fit fastening interfaces are engaged simultaneously, thus ensuring a form-fit / force-fit fastening of the system component. This allows for advantages in terms of design, access, fastening process, and also ergonomics. Brief description of the drawings

Schematic representation of the steps of a method for mounting or fastening at least one system component of an elevator system using a fastening system according to exemplary embodiments. Detailed description of the drawings

[0040] The invention will first be explained with general reference to all reference numerals and figures. Specific features or individual aspects, or aspects of the present invention that are clearly visible / representable in the respective figure, will be addressed individually in connection with the respective figure.

[0041] A positive-locking / force-locking fastening system 20 is provided for at least one load-bearing system component 3 of a lift system 1, in particular for a rail system component, comprising a plurality of positive-locking / force-locking fastening means 7 for fastening the at least one load-bearing system component 3 to at least two fastening points P1, P2 or to / in at least two fastening axes X1, X2;wherein the form-fit / force-fit fastening system 20 has a common countermeasure 10 with a first force-fit / form-fit fastening interface 11 for a first form-fit / force-fit fastening element and at least one further force-fit / form-fit fastening interface 12 for a further form-fit / force-fit fastening element and is configured to counter the first and the at least one further form-fit / force-fit fastening element against a relative movement on the common countermeasure 10 when simultaneously engaging the corresponding force-fit / form-fit fastening interfaces 11, 12 and to ensure a form-fit / force-fit fastening of the load-bearing system component 3, in particular when only one-sided and preferably only one-handed engagement on the respective form-fit / force-fit fastening element by means of only a single fastening tool 30, preferably operable with one hand.;

[0042] Improved conditions regarding access to the fasteners can be created by requiring that the fasteners only be accessible from one side, thus eliminating the need to counteract a relative rotational movement of a connecting partner. Instead, the respective connecting partner can be provided by the common counter-element, which, for example, has or consists of a solid cuboid base body 13. Consequently, recesses 5 provided for in the design (particularly for accessibility for fastening purposes) are no longer necessary, at least not to the previous extent. This also reduces the design effort, material processing effort, and material usage, and can therefore enable greater stiffness with less material; in any case, it results in greater design freedom and variations.

[0043] The fastening elements 7 for (rail) system components of the elevator systems considered here can be designed, in particular, as screws or bolts or similar positive-locking / force-locking fastening and assembly elements. The common counter-measure 10 can, for example, be designed as a cuboid rod or block.

[0044] The first force-fit / form-fit fastening interface 11 extends in particular along a / the first fastening axis X1, especially in the form of an internal thread. The further (second or third or fourth...) force-fit / form-fit fastening interface 12 extends in particular along a / the second fastening axis X2, especially in the form of an internal thread.

[0045] The fastening procedure described here includes in particular steps S1, S2 and S3, optionally also step S4: S1 Step of inserting or pre-assembling the (respective) common countermeasure; S2 step of positioning (especially relative to at least one other system component); S3 Step of properly securing the system component; S4 Step of applying or checking a predefined / predefinable torque.

[0046] The following section explains special features of the invention with reference to individual figures or embodiments.

[0047] In the Fig. Figure 1 illustrates an accessibility situation when fastening a rail system component in the conventional manner; that is, accessibility is ensured via at least one structurally provided recess, and the fastening point requires access from both sides of the rail system component, in this case, on the one hand at the head of the respective screw bolt, and on the other hand at the respective lock nut. Fig. Figure 1A shows that the fastening tool 30 must be guided through the design-provided recess 5 in order to engage with the corresponding screw (or, equivalently, lock nut). Despite the recess 5, the accessibility and visibility of the fastening point are limited, which also makes it difficult to check an already completed fastening. Fig. Figure 1B shows that while the recess 5 can ensure access, it is nevertheless comparatively small (or may only be very small for design or structural reasons), so that accessibility and visibility of the respective fastening point are adversely restricted. Fig. Figure 1C shows components of an elevator system 1, including rail system components 3, which are to be fastened or to which further system components are to be fastened. This assumes Fig. 1C also points out that for fastening rail system components 3, further components may also be provided, namely, for example, those which may be provided between the load-bearing shaft wall and the rails as such.

[0048] In the Fig. 1A, Fig. 1B, Fig. In section 1C, the area that is particularly difficult to access in the system component arrangement considered here as an example is highlighted by a dotted-line ellipse. Fig. 1C also indicates the vertical axis z (as intended, corresponding to the vertical).

[0049] In Fig. Figure 2 shows one of the locations where fastening can be carried out using the fastening system described herein. Each location has at least one elongated hole 9, which is specifically designed to accommodate assembly and relative position tolerances of the respective system component. The recess 5, also shown, is no longer required thanks to the present invention.

[0050] In Fig. Reference numeral 2 refers to a system component which, depending on the definition, is not necessarily to be considered the rail system component itself, but rather an additional component that may be provided, for example, between the load-bearing shaft wall and the respective rail. The person skilled in the art understands that the reference to the rail system component(s) described here in general terms is also to be understood synonymously as referring to such additional components arranged between the rail system component and, for example, a shaft wall, particularly since the same requirements regarding safety, positional tolerance, accessibility, load type, and the like may apply to the corresponding fastening point.

[0051] In the Fig. Figure 3 shows further details of the form-fit / force-fit fastening system 20 described here, comprising at least one common counter-measure 10 and fastening means 7 for at least one (rail) system component. In the intended assembled state, the common counter-measure 10, with at least one contact surface 14, comes into contact with the system component to be fastened (force transmission area for screw connection force). In the illustrated embodiment, the fastening means 7 engage in a force-fit / form-fit manner in through-hole internal threads 15 in the base body 14. In this way, the common counter-measure 10 defines a unique positional relationship between the at least two fastening means 7, namely in / with the two force-fit / form-fit fastening interfaces 11, 12.Optionally, the fastening system 20 can be supplemented by at least one type of washer, which is arranged along the fastening axis between fastening means 7 and counter means 10, wherein, for example, at least one washer of a first type washer 21 (in particular abutting the system component) and / or at least one washer of a second type washer 22 (in particular abutting between the system component and the first type washer) and / or at least one washer of a third type washer 23 (in particular abutting between the first type washer and the counter means) can be provided.

[0052] The fastening system 20 therefore also defines at least two fastening points (each defined or at least countered by counter means), namely a first fastening point P1 and a second fastening point P2 (similarly also a corresponding area around the respective fastening axis X1, X2).

[0053] In Fig. 3A shows a (pre-)assembled fastening system 20 in its intended arrangement on the system component to be fastened; both fastening means are engaged with the common countermeasure. A fastening tool, especially for one-handed operation (in Fig. 3A, Fig. (3B not shown) therefore only needs to engage on the side of the respective screw head, into the Fig. 3 also lying from above on the respective fastening element 7. In Fig. Figure 3B shows an embodiment with five washers 21, 22, 23 per mounting axis (three different washer types), whereby this assembly of components can essentially be attributed to the type of system component to be fastened. Those skilled in the art understand that, depending on the design of the system component to be fastened, a different assembly of the components of the fastening system 20 may also be provided.

[0054] In Fig. Figure 4 illustrates the steps of a procedure for fastening a load-bearing system component of an elevator system using at least one positive-locking / force-locking fastening system. in particular the following steps: Step S1: Insertion of a common countermeasure when interacting with at least two positive-locking / force-locking fasteners and the load-bearing system component; Step S2 Positioning the at least one system component to be fastened by relative movement; Step S3 involves properly fastening the at least one system component to be fastened by tightening the (at least two) form-fit / force-fit fasteners against the common countermeasure, in particular by means of a one-hand operable fastening tool.

[0055] Step S3 can advantageously also be carried out intermittently by alternating the engagement of the fastening tool on the first and on at least one further form-fit / force-fit fastening element for fixing relative to the common counter element.

[0056] It is understood that step S2 is a step which may depend on the specific characteristics of a given installation situation and on the type of system components to be installed, and may be particularly useful when (rail) system components are to be fixed at slotted mounting points. Those skilled in the art understand that the concept according to the invention can also be advantageously implemented if step S2 can be omitted (particularly due to different assembly constraints).
