Abstract
Description
[0001] The present disclosure relates generally to a mounting kit for an elevator position information system (shaft copying system), comprising a rail and at least one clamping element. Furthermore, the disclosure relates to a method for mounting the kit in an elevator shaft. In particular, the disclosure also relates to the elevator position information system itself.
[0002] With conventional elevators, precisely positioning the elevator car within the shaft is a complex and costly process. Previously, numerous mechanical components, such as magnetic flags and limit switches, were used, making installation in the shaft difficult and increasing investment costs. Maintenance was also complex. Safety requirements were, and still are, stringent; see EN 81-20 / 21 / 50.
[0003] Modern elevators utilize digital elevator position information systems, also known as "shaft copying systems." These systems precisely determine the position of the elevator car within the shaft, replacing conventional mechanical components. Elevator and safety functions can be implemented using SIL3-certified sensors and a SIL3-certified evaluation unit compliant with EN 81-20 / 21 / 50.
[0004] Fig. Figure 15 shows a perspective view into an elevator shaft 102, in which a conventional elevator car 104 is moved vertically between three floors S1–S3. The (absolute) position of the elevator car 104 is recorded using a conventional (digital) elevator position information system 100. Details of the system 100 are described in Figure 15. Fig. Figure 16 is enlarged and shown in isolation. The system 100 typically comprises a sensor 106, a coded tape 108, and a conventional (mounting) kit 110. The coded tape 108 is absolutely coded and is read (contactlessly) optically, magnetically, or capacitively by the sensor 106, which is attached to the cabin 104. The kit 110 comprises two elongated rails 112 and 114, which are attached to the upper and lower end regions of a conventional elevator guide rail 116 by means of screws (bolts) 118 and clamping blocks 120 (not visible in Figure 16). Fig. 15 and Fig. 16) and nuts 122 are to be fixed in a horizontal orientation on the vertically oriented elevator guide rail 116. At least two, and preferably four, clamping blocks 120 are provided for each rail 112, 114, which are positioned evenly on both sides of the elevator guide rail 116 to clamp the elevator guide rail 116 horizontally and to force-fit and fix the rails 112, 114 horizontally and transversely to the elevator guide rail 116. In this case, the front surfaces of the rails 112, 114 lie completely against the rear surface of the elevator guide rail 116. Furthermore, the system can include 100 (carabiner) hooks 124 for attaching the code band 108 to the rails 112, 114 and / or to a tension spring 126, with which the code band 108 is tensioned vertically in the shaft 102 so as not to come into contact with the sensor 106 while the cabin 104 is moved up and down.Finally, the system 100 can also include a safety band 128 that is guided around the spring 126 to protect against breakage of the tension spring 126.
[0005] The accuracy of the position determination correlates with the accuracy with which the system 100 is installed in the shaft 102. The installation includes the fastening and alignment (mounting) of the rails 112 and 114 on the elevator guide rail 116, the tensioning of the code strip 108 between the rails 112 and 114, the fastening of the sensor 106 to the car 104, and the alignment of the sensor 106 to guide the code strip 106 through a reading area of the sensor 106 without contact.
[0006] When mounting rails 112 and 114, at least two clamping blocks 120 must be attached to each, which is time-consuming. Furthermore, there is a risk that the installer might drop one of the clamping blocks 120 during installation, resulting in additional work. Since the clamping blocks 120 must be fixed on both sides of the elevator guide rail 116, the fixing can only be done sequentially, which in turn carries the risk that rails 112 and 114 will not be correctly aligned relative to rail 116.
[0007] Rails 112 and 114 lie flat against the elevator guide rail 116. This can lead to tilting and slippage of rails 112 and 114, where the contact pressure is inversely proportional to the area. Vibrations, overtightened screws 118, or excessive load can loosen, damage, and in the worst case, completely detach the screw connections.
[0008] An unintentional mounting of rails 112 and 114 at an orientation other than 90° to the elevator guide rail 116 is possible because the installer may misalign rails 112 and 114 from the outset. As a result, the code strip 108 runs at an angle in shaft 102. In this case, sensor 106 can no longer read the code correctly, so cabin 104 can no longer be positioned precisely. This can create a tripping hazard when people enter and exit cabin 104. Furthermore, increased wear due to friction between the code strip 108 and sensor 106 can occur.
[0009] In the event of a repair, many individual parts always need to be replaced and shipped. The number of parts naturally also plays a role in the original delivery.
[0010] Document JP H10-182 024 A concerns a landing position detection device for an elevator.
[0011] Document EP 2 174 902 A1 concerns a fixing bracket for an elevator guide rail.
[0012] Document FR 2 996 216 A1 relates to a fixing device for fixing an elevator guide to a wall, which has elements that are movable relative to each other in order to change a distance between cavities and bolts arranged to prevent an increase in the distance in order to lock the guides in the cavities.
[0013] Therefore, one objective of the present disclosure is to provide an improved mounting kit for an elevator position information system that overcomes the aforementioned disadvantages. Furthermore, an improved elevator position information system is to be provided.
[0014] This problem is solved by a mounting kit for an elevator position information system according to claim 1.
[0015] The kit prevents any possible movement between the rail and the elevator guide rail after the rail has been installed.
[0016] The rail can only be mounted at the predetermined angle, i.e., perpendicular to the elevator guide rail. Misalignment of the rail during installation is impossible. The rail is hooked onto the elevator guide rail on one side and secured on the opposite side, a task easily accomplished by a single installer. After hooking the rail in place, the installer gently pulls it towards the opposite side with one hand, thus maintaining its position and alignment, while using the other hand to position and secure the clamping element.
[0017] Installation is simplified because a single clamping element is sufficient to fix each rail to the elevator guide rail. This reduces installation time and the number of components required, thus lowering costs.
[0018] Preferably, each of the four fixing elements is aligned along a transverse direction of the rail that corresponds to a longitudinal direction of the elevator guide rail in the assembled state.
[0019] This alignment of the fixing elements ensures that the rail can only be mounted vertically on the elevator guide rail. Misalignment (deviating from 90°) is impossible. An installer can only mount the rail correctly, i.e., at a 90° angle.
[0020] In particular, at least one of the fixing elements is a tab which: is formed integrally with the body; projects from the body in the vertical direction of the rail; and forms an angle of less than or equal to 90° with the rest of the body when viewed along a transverse direction of the rail.
[0021] The tab is technically simple to manufacture, for example, by punching, milling, cutting, or similarly forming the edge of the tab into a base body of the rail, with the tab then being bent out of the base body to form the desired angle. The tab should be sufficiently long in the transverse direction of the rail to ensure the rail is perpendicular to the elevator guide rail. Of course, more than one tab can also be formed in the base body, but in this case, they must be aligned along a uniform line in the transverse direction.
[0022] Alternatively or additionally, at least one of the fixing elements can be an angle element that is (subsequently) permanently attached to the body and that forms an angle of less than or equal to 90° with the body when viewed in a transverse direction of the rail.
[0023] The body has a U-shaped cross-section perpendicular to the longitudinal direction of the rail, defined by a base leg and two side legs connected to each other; and the at least one fixing element is designed and positioned such that the elevator guide rail rests only on the side legs when mounted.
[0024] The U-shaped cross-section reduces the contact area between the rail and the elevator guide rail. The elevator guide rail rests only on the side flanges. This increases the surface pressure, thus strengthening the positive connection between the rail and the elevator guide rail under the same force. The rail is therefore more securely fixed. This prevents any displacement of the rail relative to the elevator guide rail and also prevents misalignment of the rail relative to the elevator guide rail.
[0025] Furthermore, it is advantageous if: each of the side legs has a recess that forms one of the fixing elements and has a notch section and a bearing section; each of the notch sections defines a notch in the respective side leg with an angle of less than or equal to 90 degrees, the notch being arranged in the longitudinal direction of the rail between the ends of the rail; and each of the bearing sections extends in the longitudinal direction of the rail from the respective notch section towards the second end.
[0026] The fixing elements are technically easy to manufacture. They can be machined from a U-profile by removing material from the side legs in the area of the notch and bearing sections. In other words, standard U-profiles can be used for the rail and modified in just a few steps to create the required fixing elements.
[0027] Preferably, each of the bearing sections extends from the respective notched section to the second end.
[0028] Here, too, the simplified manufacturing process plays a role.
[0029] Installation is simplified because the rail only needs to rest against the elevator guide rail with its bearing section and then be pulled lengthwise against the elevator guide rail to achieve the desired vertical alignment. No additional pivoting of the rail around the longitudinal axis of the elevator guide rail is required.
[0030] In another special version, the kit includes exactly two fixing elements, with one of the fixing elements being formed in each of the side legs.
[0031] Two fixing elements are sufficient to achieve the desired perpendicular alignment of the rail relative to the elevator guide rail. No further fixing elements, regardless of their shape, are required, thus simplifying the manufacturing of the rail.
[0032] In particular, the clamping element is designed to be positively locked to another longitudinal edge of the elevator guide rail, which is opposite the longitudinal edge that is received by the at least one fixing element.
[0033] The positive-locking connection between the elevator guide rail and the clamping element simplifies installation. The clamping element is automatically aligned correctly by the installer while they position it on the elevator guide rail. This positive locking also aids in the alignment of the clamping element during bolt tightening, as there is a risk of the clamping element rotating during this phase, especially when using screws.
[0034] Preferably, the kit also includes the bolt, which can be formed integrally with the clamping element.
[0035] Alternatively, the bolt represents a separate component.
[0036] Regardless of how the bolt is designed, it interacts with a nut to force-fit the rail to the elevator guide rail via the clamping element. The bolt preferably has a head and a shaft with an external thread, and is further configured to pass through a hole in the clamping element and secure the clamping element by means of the nut.
[0037] Preferably, the rails and the clamping element are each provided in duplicate.
[0038] Such a kit therefore includes both the upper and lower rails for attaching the code strip in the elevator shaft.
[0039] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of this disclosure.

[0041] The present disclosure relates to a novel (fastening) kit 10 for a novel elevator position information system 12, which is in Fig. 13 is shown. System 12 differs in kit 10 from the conventional elevator position information system 100. Fig. 15 and Fig. 16.
[0042] The kit 10 of the present disclosure generally has at least one rail 14 and at least one clamping element 16 per rail 14, which is provided separately from the rail 14.
[0043] Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 to Fig. Figure 6 shows a first embodiment of kit 10.
[0044] Fig. Figure 1 shows a perspective view of the mounting kit 10, which will subsequently be referred to simply as kit 10. Kit 10 is available in the Fig. Figure 1 shows the rail in its assembled state. In the assembled state, the rail 14 is positively locked to the (conventional) elevator guide rail 116 via the clamping element 16 and fixed with respect to its orientation and position. In the assembled state, the rail 14 is oriented perpendicular to the elevator guide rail 116. This means that a longitudinal direction X (length) of the rail 14, which is in the Fig. 1, indicated by a dashed line, extends perpendicularly to a longitudinal direction of the elevator guide rail 116, which is in Fig. 1 is also indicated by a dashed line. The longitudinal direction of the elevator guide rail 116 corresponds to a transverse direction Y (width) of the rail 14. The longitudinal direction X of the rail 14 and the transverse direction Y of the rail 14 are therefore perpendicular to each other. A vertical direction Z of the rail 14 is perpendicular to the plane spanned by the directions X and Y. The directions X, Y, and Z thus define a Cartesian coordinate system.
[0045] The elevator guide rail 116 of the Fig. Figure 1 has, by way of example, a T-shaped cross-section perpendicular to its longitudinal direction. The elevator guide rail 116 can also have other cross-sectional shapes with a high section modulus, wherein the elevator guide rail 116 always has a plate-like base body with a first outer longitudinal edge 130-1 and a second outer, opposite longitudinal edge 130-2, which are separated from each other by a flat back surface to which the rail 14 is to be attached. The first longitudinal edge 130-1 is located in Fig. The first longitudinal edge 130-2 engages with the rail 14, and the second longitudinal edge 130-2 engages with the clamping element 16, while the back of the elevator guide rail 116 rests on the rail 14, so that the assembly 10 clamps the elevator guide rail 116 in the longitudinal direction X and is positively locked to it in the direction Z, as will be explained in more detail below. The elevator guide rail 116 itself is not part of the assembly 10.
[0046] The rail 14 generally has an elongated, plate-shaped body 18 with a total length L ( Fig. 5) The body 18 extends essentially along the longitudinal direction X of the rail 14. The body 18 has a width B, preferably constant (see Fig. 6) in the transverse direction Y of the rail 14. Furthermore, the body 18 has at least one fixing element 20, which can be designed differently, as will be explained later. In the first embodiment in the Fig. Figure 1-6 shows that the body 18 has two fixing elements 20-1 and 20-2, which are formed integrally with the body 18 in lateral elements thereof.
[0047] The body 18 also generally has an elongated hole 22 for attaching and fixing the rail 14 to the elevator guide rail 116 via the clamping element 16. The elongated hole 22 extends along the longitudinal direction X of the rail 14. The elongated hole 22 is preferably oriented parallel to the longitudinal direction X. It is understood that the elongated hole 22 could also be oriented obliquely to the longitudinal direction X. It is important that the clamping element 16 is positively guided by the elongated hole 22 in the longitudinal direction Y of the rail 14 in order to clamp the elevator guide rail 116 in the longitudinal direction X of the rail 14. The clamping element 16 is therefore movable in the longitudinal direction X, as indicated by a double arrow in Fig. 1 is indicated. For this purpose, a bolt 24 engages along the vertical direction Z transversely to the longitudinal direction X through the elongated hole 22.
[0048] Bolt 24 is shown in detail in the sectional view of the Fig. Figure 3 shows the bolt 24 as an example screw. The bolt 24 has a head 26, a shank 28 with a smaller diameter than the head 26, and an external thread 30 for turning a nut 32 onto the bolt 24. In the assembled state, the nut 32 is located on the back of the rail 14, which is in Fig. 1 is not visible. The bolt 24 engages through a hole 34 in clamping elements 16 (see figure). Fig. 4), which in the assembled state extends in the vertical direction Z through the clamping element 16, cf. Fig. 9 and Fig. 10.
[0049] Rail 14 of the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. 7 can be manufactured from a commercially available profile, preferably made of metal, which is an elongated component. The term "profile" here refers both to the component (rail) itself and its cross-section. Examples include I-profiles, T-profiles, U-profiles, L-profiles, and Z-profiles. These profile designations are derived from the shape or geometry of the respective cross-section. In the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. Figure 7 shows an example of a U-profile, as can be seen particularly from the side view of the Fig. 6, which is rail 14 of the Fig. 1, Fig. 2, Fig. 3 to Fig. 4 is illustrated in isolation, and from the cross-section of the Fig. 4 results. In the Fig. 6. Looking in the negative longitudinal direction X at rail 14 (see arrow V in Fig. 2).
[0050] The U-profile of rail 14 is incorporated into the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. 7 is defined by two side legs 36-1 and 36-2 and by a base leg 38. The side legs 36-1 and 36-2 are aligned parallel to each other and each extends in the XZ plane. The base leg 38 extends in the XY plane and forms an angle of 90° with each of the side legs 36-1 and 36-2. The transition areas between the side legs 36 and the base leg 38 are preferably formed with a radius, in particular to better transfer forces into the base leg 38 that are exerted on the side legs 36, as is the case when the nut 32 is tightened.
[0051] Each of the side thighs 36 of the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. 7 consists of a cantilever section 40, a notch section 42 and a bearing section 44 along the longitudinal direction X, as can be seen, for example, in the side view of the Fig. Figure 5 illustrates the second lateral leg 36-2.
[0052] As in the Fig. 1 and Fig. As shown in Figure 2, the cantilever section 40 projects beyond the elevator guide rail 116 and into the elevator shaft (not illustrated) to attach the code strip 108 to the rail 14. For attaching the code strip 108, one or more holes 46 may be provided in one or both side legs 36, where the hooks 124 (see Figure 2) are located. Fig. 16) be attached.
[0053] The notched section 42 adjoins the cantilever section 40 in the longitudinal direction X and is designed to receive the longitudinal edge 130-1 of the elevator guide rail 116 (positively interlocking), so that the rail 14 is oriented perpendicular to the elevator guide rail 116 when the rail 14 is mounted on the elevator guide rail 116, as shown in the Fig. 1, Fig. 2, Fig. 3 to Fig. Figure 4 shows that the 90° angle between rails 14 and 116 is not mandatory. The angle between rails 14 and 116 could also deviate from 90°, but this angle is predetermined and then remains unchanged. The angle between the upper rail 14 in the shaft and the elevator guide rail 116, and the angle between the lower rail 14 in the shaft (see Figure 4) are not fixed. Fig. 15 and Fig. 16) could differ from one another. The notched sections 42 would have to be aligned accordingly. This applies generally to the fixing element(s) 20.
[0054] The notch section 42 represents the fixing element 20 in this case. As shown in the sectional view of the Fig. As illustrated in Figure 3, the notch section 42 defines a (notch) angle α for the (positive-locking) engagement of the longitudinal edge 130-1 of the elevator guide rail 116 in the rail 14 or in the side leg 36. The angle α is less than or equal to 90°. The angle α is preferably acute and in particular 45°, which simplifies the engagement of differently shaped longitudinal edges 130. Positive-locking engagement of the longitudinal edge 130-1 is understood to mean contact between the longitudinal edge 130 and the notch section 42 at at least two points on the longitudinal edge 120. Positive-locking connections are generally created by the interlocking of at least two connecting partners. This prevents the connecting partners from separating from each other. In other words, in a positive-locking connection, one connecting partner blocks the path of the other connecting partner.Such closures occur in at least one direction, here in the longitudinal direction X of rail 14.
[0055] In the Fig. 3 is a lower end and an upper end of the longitudinal edge 130-1 in contact with the notch section 42. It is understood that the contour of the notch section 42 can be formed congruently with the contour of the elevator guide rail 116, but this involves a higher manufacturing effort and limits the use of the rail 14 to specific elevator guide rail types. The acute-angled notch, which in Fig. As illustrated in Figure 3, the rail 14 has the advantage that it can be used for a variety of differently dimensioned and shaped longitudinal edges 130 of the elevator guide rails 116.
[0056] The notch section 42 is adjoined in the longitudinal direction X by a bearing section 44 of the side leg 36, where the side leg 36 has a reduced height (in the direction Z) compared to the cantilever section 40, see Fig. 5. The bearing section 44 serves to support the rail 14 on the elevator guide rail 116, as shown in Fig. Figure 3 illustrates this. The contour of the bearing section 44 seamlessly joins the contour of the notch section 42 and preferably extends to the second end 48 (elevator guide rail end) of the rail 14, which is opposite the other first end 50 (code band end) in the longitudinal direction X. The bearing section 44 can be shorter in the longitudinal direction X, see Figure 3. Fig. 7, but must be able to fully accommodate the elevator guide rail 116. A shortened bearing section 44 is shown in the side view of the Fig. Figure 7 illustrates a second embodiment of rail 14.
[0057] The length of the bearing section 44 in the longitudinal direction X can be selected such that the rail 14 is in a first (initial) position 52, which is in Fig. 7, indicated by a dotted line, can be pivoted into a second (end) position 44 by a tilting movement 53, which is in the Fig. Figure 7 is illustrated by a dashed line. It is understood that in the case of actual installation in the elevator shaft, the rail 14 is tilted to reach the end position 54 because the elevator guide rail 116 is fixed in the elevator shaft. This length selection, which depends on the width of the back of the elevator guide rail 116, further simplifies installation because the rail 14 has only minimal play in the longitudinal direction X in the end position 54. This significantly facilitates the final positioning of the rail 14 and its final fixing using the clamping element 16, which is located in Fig. 7 is not shown.
[0058] The following describes the assembly of rail 14 of the Fig. 1, Fig. 2, Fig. 3 to Fig. 4 on the elevator guide rail 116 with reference to Fig. 14 will be described.
[0059] In a first step S10, the fitter places the rail 14 in the area of the bearing sections 44 on the back of the elevator guide rail 116 and moves the rail 14 so that the fixing elements 20 engage with the longitudinal edge 130-1.
[0060] As soon as the fixing elements 20 of the rail 14 are in contact with the elevator guide rail 116, a slight pull on the rail 14 in the longitudinal direction X is sufficient to keep the rail 14 aligned perpendicular to the elevator guide rail 116. The alignment occurs automatically because the fixing elements 20-1 and 20-2 in the transverse direction Y of the rail 14 are designed and aligned parallel to the longitudinal direction of the elevator guide rail 116, as shown in the Fig. 1 and Fig. Figure 2 illustrates this. In this state, the installer can hold rail 14 with one hand.
[0061] With the other hand, the fitter can position the clamping element 16 by guiding the bolt 24 through the elongated hole 22 along the Z direction until the clamping element 16 sits on the rail 14 (S12).
[0062] The clamping element 16 is then moved in the longitudinal direction X towards the elevator guide rail 116 until the clamping element 16 abuts the second longitudinal edge 130-2, as shown in the Fig. 1 and Fig. 3 is shown (S14).
[0063] The fitter can then screw the nut 32 onto the bolt 24 from the back of the rail 14 and tighten it (S16).
[0064] Then rail 14 is finally mounted.
[0065] As in the Fig. As shown in Figure 3, the clamping element 16 is configured for the positive locking engagement of the second longitudinal edge 130-2, wherein a top surface of the clamping element 16 is preferably oriented parallel to the base leg 38 in the connected state. The clamping element 16 is located in the Fig. 3 rests exclusively on the elevator guide rail 116. This means that the clamping element 16 does not touch the rail.
[0066] However, it is preferred if the clamping element 16 also rests on the rail 14 with a projection 64, as shown in Fig. 3 is indicated by a dotted line and with reference to the Fig. 9 and Fig. 10 will be described in more detail.
[0067] Fig. Figure 4 illustrates that the force exerted by the bolt 24 on the clamping element 16 by tightening the nut 32 in direction Z is transferred via the clamping element 16 into the elevator guide rail 116 and from the elevator guide rail 116 into the bearing sections 44 of the side legs 36. In this case, the elevator guide rail 116 only contacts the rail 14 in the area of the contact points 60-1 and 60-2, which are shown in Fig. Figure 4 shows the contact points 60-1 and 60-2. These are the upper surfaces of the bearing section 44, which make full contact with the underside of the elevator guide rail 116. This contact area is significantly smaller in the prior art, where the back of the elevator guide rail 116 makes full contact with the entire rail 14. By increasing the surface pressure (p=F / A) between the rail 14 and the elevator guide rail 116, the risk of the rail 14 slipping off the elevator guide rail 116 is reduced. It also reduces the risk of the clamping element 16 moving away from the elevator guide rail 116 along the elongated hole 22, which could result in the cantilever section 40 tipping over.This means that the vertical alignment of the rail 14 relative to the elevator guide rail 116 is ensured in this way because a high force transmission is achieved between the components involved, so that the bolt 24 cannot come loose (not over a longer period of time).
[0068] The Fig. 9 and Fig. Figure 10 shows a clamping element 16 in a perspective view from below and above. A lower region of the clamping element 16 is stepped such that it has a recess 62 and a projection 64. The recess 62 represents the region of the clamping element 16 where the material of the body of the clamping element 16 is reduced in the vertical direction Z to provide a positive-locking engagement with the longitudinal edge 130-2. The projection 64 represents a region where the body of the clamping element 16 projects in the vertical direction Z, in particular to bear against the rail 14. The recess 62 and the projection 64 preferably extend over the entire width (Y-direction).
[0069] The contour of the recess 62 is preferably selected such that the clamping element 16 lies fully against the elevator guide rail 116, as shown in Fig. Figure 3 shows that the contour could also be chosen similarly to that of the fixing element 20.
[0070] The height of the clamping element 16 (Z-direction in Fig. 9) is preferably selected such that the clamping element 16, in the assembled state, rests fully on the guide rail 116 on the rail 14, and that the bolt 24 extends parallel to the vertical direction Z, as is also the case in Fig. 3 is the case. It is understood that both the shape or contour of the recess 62 and the overall height of the clamping element 16 in the area of the projection 64 are preferably adapted to the shape of the elevator guide rail 116.
[0071] The perpendicular alignment of the bolt 24 to the rail 14 ensures that the clamping element 16 is positionally secure. Positionally secure means that the clamping element 16, the elevator guide rail 116, and the rail 14 do not move relative to each other when the nut 32 is tightened.
[0072] In Fig. Figure 10 illustrates the top surface 65 of the clamping element 16, which, in addition to the hole 34 for guiding the shaft 28 of the bolt 24, may have a further recess 66, which in turn is designed for the positive locking reception of the head 26 of the bolt 24.
[0073] This design of the clamping element 16 simplifies assembly. The bolt 64 is inserted through the hole 34 into the clamping element 16 until the head 26 of the bolt 24 is positively engaged in the further recess 66. The installer can then insert the clamping element 16 with their fingers or the palm of their hand through the elongated hole 22 into the rail 14 and move (slide) it in the longitudinal direction X of the rail 14 towards the elevator rail 16 until the recess 62 engages positively with the longitudinal edge 130-2 of the elevator guide rail 116. While maintaining pressure with the palm of their hand, the installer can then screw the nut 32 onto the bolt 24 from the back of the rail 14, see p. 16 in Fig. 14. The positive fit between the head 26 and the further recess 66 facilitates the tightening of the nut 32 because the bolt 24 does not rotate in this case. However, if the torque applied when tightening the nut 32 becomes too high, the clamping element 16 may rotate along the longitudinal axis of the shaft 28 because the installer can no longer hold the clamping element 16. In this case, the clamping element 16 abuts one of the side legs 36, thus preventing further rotation. The side leg 36 acts as a stop. If the nut 32 is then tightened further, the clamping element automatically pulls itself into the position specified in the [reference to the previous sentence] due to the positive fit between the recess 62 and the longitudinal edge 130-2. Fig. As shown in Figure 1. The assembly can therefore be carried out by a single fitter while maintaining the desired alignment of the rail 14 and applying a high torque to tighten the nut 32.
[0074] Fig. Figure 11 shows a further embodiment of the rail 14, which has a fixing element 20 provided as a tab 68 in the body 14, which preferably again has a U-shaped cross-section perpendicular to the longitudinal direction X of the rail 14. The tab 68 is inclined at an angle α relative to the base leg 38 and projects obliquely upwards from the base leg 38, i.e., in the positive Z direction. The tab 68 extends beyond the side legs 36 in the vertical direction Z of the rail 14 to positively lock the elevator guide rail 116 in the manner of Fig. 1 between itself and the side legs 36, as can also be seen in the side view of the Fig. 12 is indicated.
[0075] In the Fig. 12 is the tab 20 of the Fig. 11 illustrated by a dotted line. Fig. 11 and Fig. Figure 12 shows that a single fixing element 20 alone can be sufficient to effect the vertical orientation of the rail 14 relative to the elevator guide rail 116.
[0076] Furthermore, the Fig. 11 and Fig. 12, that the fixing element(s) 20 can also be positioned in a location other than the side legs 36.
[0077] It goes without saying that rail 14 does not have to be a U-shaped profile. Rail 14 of the Fig. 11 and Fig. 12 could also be formed solely by the base leg 38, so that the rail 14 is designed as a strip without side legs 36. In this case, the elevator guide rail 116 is supported directly and fully on the base leg 38 in the assembled state, whereby the positive locking connection by the fixing element(s) 20 is still ensured.
[0078] As an alternative to the tab 68, a separate angle element 70 could be permanently attached to the rail 14 to provide a positive-locking connection for the elevator guide rail 116. The angle element 70 is in Fig. Figure 12 is illustrated by way of example as an L-shaped angle designed for the positive locking of the elevator guide rail 116. The angle element 70 preferably has a section that is perpendicular to the rail 14 and another section that is oriented parallel to the rail 14, as shown in Fig. 12 is shown.
[0079] It is understood that the kit 10 can include two rails 14, which are then mounted separately at the top and bottom on the elevator guide rail 116 in the same way.
[0080] Furthermore, it is understood that for the purpose of increased safety, a further, second clamping element 16 can be used per rail 14, which is opposite the first clamping element 16 on the elevator guide rail 116, i.e. on the longitudinal edge 130-1 (cf. Fig. 1 (the second clamping element 16 is not shown there), is attached to increase the (contact) force with which the rails 14 and 116 are pressed against each other in the vertical direction Z. It also prevents the rails 14 and 116 from slipping against each other (loss of friction). This second clamping element 16 preferably serves solely to increase the contact force, but not to align the rail 14 relative to the rail 116.
[0081] Fig. Figure 13 shows a block diagram of the aforementioned elevator position information system 12, which uses the kit 10 of the present disclosure instead of the conventional kit 110, which is described in the Fig. 15 and Fig. 16 is shown. System 12 of the Fig. 13 differs from the conventional system 100 of Fig. 15 is only included in kit 10. All other components, such as the sensor 106, the code tape 108, the tension spring 126 and the hook(s) 124, are unchanged.
