DETAILED DESCRIPTION

[0040] First, a shaft information system 1 for an elevator system 2 (FIG. 7) having a device 3 and information carrier 4 according to an exemplary embodiment of the invention is described using FIGS. 1 and 2. FIG. 1 shows the shaft information system 1 for the elevator system 2 with the device 3 for retaining an information carrier 4 which is fastened to a rail 5 of the elevator system 2, according to the exemplary embodiment of the invention in a three-dimensional and schematic detail diagram. FIG. 2 shows the device 3 shown in FIG. 1 for retaining the information carrier 4 in a schematic detail diagram from the viewing direction indicated with II. The information carrier 4 is part of the shaft information system 1 but not necessarily part of the device 3 which is used to retain the information carrier 4. This means that the device 3 can also be produced and marketed and mounted during erection of the elevator system 2 independently of the information carrier 4. Furthermore, a device 3 can also be suitable for differently designed information carriers 4.

[0041] The information carrier 4 is mounted in an elevator shaft 6 of the elevator system 2 such that it extends at least substantially through the entire elevator shaft 6 of the elevator system 2. The information carrier 4 can for example be connected to a shaft floor 7 and clamped vertically upwards against same.

[0042] The operating principle of the device 3 consists in retaining the information carrier 4 extending through the elevator shaft 6 at a point 8 of the information carrier 4. Vibrations of the information carrier 4 which can occur perpendicular to a predefined extent 9 of the information carrier 4 through the elevator shaft 6 should be substantially prevented or at least reduced by this retention. To simplify the description, directions (transverse directions) 10, 11 which are perpendicular to each other and perpendicular to the predefined extent 9 are considered here.

[0043] The device 3 has a retaining element 15, a clamping element 16, a clamping force transmission means 17, a connection piece 18, a supporting arm 19, a first fastening clip 20 and a second fastening clip 21. The individual parts 15 to 21 of the device 3 can be provided once or multiple times depending on the design of the device 3.

[0044] In this exemplary embodiment, the connection piece 18 is fastened to the rail 5 of the elevator system 2 by means of the supporting arm 19 via the two fastening clips 20, 21. In a modified design, the supporting arm 19 can also be connected to the rail 5 via a possibly modified single fastening clip 20. Furthermore, a modification is conceivable in which the connection piece 18 is connected to the rail 5 via two supporting arms 19 and in each case one or two fastening clips 20, 21.

[0045] Fastening means 22, 23 which are used to fasten the fastening clips 20, 21 to the supporting arm 19 are in the form of screw-fastenings 22, 23 in this exemplary embodiment. When the device 3 is mounted, the screw-fastenings 22, 23 are tightened to produce a frictional fit with the rail 5. The fastening clips 20, 21 can be elastically deformable here.

[0046] The connection piece 18 ensures a connection between the clamping element 16 and the retaining element 15, which allows tensioning of the clamping element 16 relative to the retaining element 15 so that a clamping force F is applied. In this exemplary embodiment, the clamping force F is parallel to the direction 10. Several variants are conceivable here. For example, the retaining element 15, the clamping element 16 and the connection piece 18 are formed in one piece, for example from a metal sheet. A design is also conceivable in which the retaining element 15, the clamping element 16 and the connection piece 18 are each formed in one piece, wherein the clamping element 16 is connected to the connection piece 18, and the retaining element 15 is connected to the connection piece 18. Furthermore, the clamping element 16 and the connection piece 18 can be formed in one piece and connected to the retaining element 15.

[0047] In this exemplary embodiment, the clamping element 16 is connected to the connection piece 18 via a screw connection 24. In this exemplary embodiment, the retaining element 15 and the connection piece 18 are formed in one piece and connected to the supporting arm 19 via a screw connection 25.

[0048] The connection piece 18 has an opening 26 in the form of a punched hole 26 through which one end 27 of the supporting arm 19 extends and which is matched to the geometry of the supporting arm 19 in order to prevent rotation of the connection piece 18 about the screw connection 25 relative to the supporting arm 19.

[0049] The mounting of the clamping force transmission means 17 and the preloading of the clamping element 16 can take place in different ways. In one possible mounting process, the clamping element 16 is, after being fastened to the rail 5 via the connection piece 18 and the supporting arm 19, initially in its relaxed starting position, which is indicated by the dashed line 30. First, one end 31 of the clamping force transmission means 17 can be connected to the information carrier 4 at the point 8 of the information carrier 4. Then the other end 32 of the clamping force transmission means 17 can be connected to the clamping element 16. The length 33 of the clamping force transmission means 17 between its ends 31, 32 is predefined such that a fastening point 34 on the clamping element 16, at which the end 32 is connected to the clamping element 16, must be moved by a preloading distance 35 at least approximately along, in this case counter to, the direction 10. The fastening point of the clamping element 16 in the starting position 30 is indicated here with reference sign 34A. Strictly speaking, an arcuate movement occurs, so the movement of the fastening point 34A into the fastening point 34 takes place only partially or approximately along the direction 10.

[0050] The minimum effective clamping force F is predefinable via the predefined length 33. The selection of the material and the design of the clamping element 16, in particular its material thickness 36 and a distance 37 of the fastening points 34A and 34 from the screw connection 24, that is, the fastening 24 on the connection piece 18, which define the spring constant of the clamping element 16, have an effect on the clamping force F. Therefore, there are several possibilities for adapting the minimum effective clamping force F, that is, the clamping force F in the starting state and the rise in the clamping force on further deflection, to the application in question. The starting state means in this case the arrangement of the information carrier 4 directly on the retaining element 15, which means that the point 8 of the information carrier 4 is situated on the predefined extent 9 which is indicated here by a dash-dotted line 9.

[0051] The clamping force transmission means 17 can thus be connected to the information carrier 4 at the point 8 of the information carrier 4. Furthermore, the clamping element 16 can be tensioned such that the information carrier 4 is loaded with the clamping force F via the clamping force transmission means 17 against at least one contact region 38, 39 provided on the retaining element, the minimum effective clamping force F being set via the preloading distance 35. The retaining element 15 is positioned in the elevator shaft 6 in an at least substantially stationary manner.

[0052] In this exemplary embodiment, the clamping force transmission means 17 is designed substantially as a tensioning wire 40. The clamping force transmission means 17 also has a head 41 at the end 31. During mounting, the tensioning wire 40 is guided through a through-opening 42, in particular through-bore 42, formed in the information carrier 4 until the head 41 bears against a front 43 of the information carrier 4. The through-opening 42 and the front 43 of the information carrier 4 are indicated, inter alia, in FIG. 3A.

[0053] The clamping force transmission means 17 is thus designed such that it can be guided through the through-opening 42 formed in the information carrier 4. Furthermore, the head 41, via which the clamping force transmission means 17 can be connected to the information carrier 4 at the point 8 of the information carrier 4 owing to the clamping force F, is formed on the end 32 of the clamping force transmission means 17. This is because, owing to the clamping force F, the head 41 always bears against the front 43 of the information carrier 4, and therefore the clamping force transmission means 17 is suspended by the head 41 at the point 8 in the information carrier 4.

[0054] The retaining element 15 has a through-opening 44 which is situated between the first contact region 38 and the second contact region 39. Furthermore, the retaining element 15 has a first lateral retaining bar 45 and a second lateral retaining bar 46, the through-opening 44 being situated between the first lateral retaining bar 45 and the second lateral retaining bar 46. The clamping force transmission means 17 runs through the through-opening 44 when in the mounted state. The clamping force transmission means 17 runs from the clamping element 16 on one side to the information carrier 4 on the other side. When the information carrier 4 bears against the contact regions 38, 39, the information carrier 4 is situated between the two lateral retaining bars 45, 46 in the mounted state.

[0055] During operation, a certain guidance or movement limitation is ensured in this manner for the clamping force transmission means 17. The extending of the clamping force transmission means 17 through the through-opening 44 limits possible movements of the clamping force transmission means 17 and thus also of the point 8 of the information carrier 4. In particular, the information carrier 4 cannot jump behind the retaining element 15 as viewed in the direction 10. Moreover, the retaining bars 45, 46 ensure further positioning along the direction 11 when the information carrier 4 bears against the contact regions 38, 39. In the example, the through opening 44 is designed such that a vertical displacement of the information carrier 4 relative to the retaining element 15 is possible. The vertical displacement is a displacement along the extent 9 of the information carrier 4.

[0056] FIG. 2 schematically shows a possible position of a detection device 47. To detect the information stored on the information carrier 4 by the detection device 47, it is necessary in this exemplary embodiment for the information carrier 4 to be situated at least at a reading distance 48 from a read device 58 of the detection device 47. To achieve this, the information carrier 4 is moved over a distance 49 counter to the direction 10 and brought towards the read device 58 of the detection device 47. This takes place in relation to the position of the detection device 47 relative to the information carrier 4 viewed along the predefined extent 9, that is, in relation to the current height or position of an elevator car 80 (FIG. 7) in the elevator shaft 6.

[0057] If the detection device 47 is in the region of the retaining element 15, for example, the information carrier 4 is lifted locally from the contact regions 38, 39 of the retaining element 15, in order to ensure the reading distance 48 locally between the information carrier 4 and the detection device 47. When the detection device 47 has passed through the retaining element 15 and is sufficiently far away from the retaining element 15 viewed along the extent 9, the information carrier 4 bears back against the contact regions 38, 39 owing to the clamping force F. In this case, the lateral retaining bars 45, 46 can act as guides to limit any possible play for positioning the information carrier 4 along the direction 11.

[0058] The design of the clamping element 16 is matched to the distance 49 necessary for bringing the information carrier 4 towards the detection device 47. In this case, the clamping element 16 can be tensioned such that the information carrier 4 can be lifted from the contact regions 38, 39 of the retaining element 15 at least approximately counter to the clamping force F, that is, at least approximately counter to the direction 10, by the detection device 47; possible designs for ensuring the function of lifting and guiding the information carrier 4 are described in more detail using FIG. 3A to 5B.

[0059] In this exemplary embodiment, the clamping element 16 is in the form of a clamping bracket 16. In the starting state, greater or lesser bending of the clamping bracket 16 is produced depending on the length 33 of the tensioning wire 40 of the clamping force transmission means 17, as a result of which bending the minimum effective clamping force F is set.

[0060] FIG. 3A shows a detection device 47 of a shaft information system 1 having a guiding structure 50 which has side pieces 51, 52, for guiding the information carrier 4 in a schematic detail diagram corresponding to a first possible design. The side pieces 51, 52 are connected to each other. The side pieces 51, 52 are inserted into a receptacle 53 in the detection device 47. This defines the position of the side pieces 51, 52 relative to each other. The side pieces 51, 52 of the guiding structure 50 leave a cut-out 54 exposed.

[0061] In the mounted state, the information carrier 4 is inserted into the guiding structure 50. Here, the clamping force F is applied to the information carrier 4 in the direction 10, as is described by way of example using FIGS. 1 and 2. The guidance of the information carrier 4 is implemented such that the information carrier 4 cannot be pulled out of the guiding structure 50 when in the mounted state. This is not possible even if the information carrier 4 is tilted or twisted along its extent 9.

[0062] FIG. 3B shows the side pieces 51, 52 of the detection device 47 shown in FIG. 3A during a mounting process for inserting the information carrier 4 into the detection device 47. In this design, the side pieces 51, 52 are connected to each other via a common back 55, which can be bent at one point 56 in this exemplary embodiment. In possible modifications, the back 55 can also be bendable at multiple points 56 or overall. As a result, the two side pieces 51, 52 are pivotable relative to each other, as shown here by an angle 57. For example, pivoting with an angle 57 of 40 can be made possible. In the pivoted state, the cut-out 54 between the side pieces 51, 52 is opened further to a certain extent so that the information carrier 4 can be inserted between the side pieces 51, 52. Then, the side piece 52 is pivoted back relative to the side piece 51 so that the angle 57 disappears. The guiding structure 50, together with the side pieces 51, 52, can then be inserted into the receptacle 53. This ensures reliable guidance of the information carrier 4 in the detection device 47.

[0063] The information carrier 4 guided through the guiding structure 50 can thereby be brought into the reading distance 48 in relation to a read device 58 of the detection device 47. For example, the read device 58 can be in the form of an optical read device which reads information stored on the information carrier 4. The position of the read device 58 in relation to the information carrier 4 is illustrated in FIG. 3A by a dash-dotted line. The guiding structure 50 and the read device 58 can be arranged suitably relative to each other. In particular, a vertical offset is possible. Suitable openings in the guiding structure 50 to allow optical reading of the information are also conceivable.

[0064] When the detection device 47 passes through the retaining element 15, the cut-out 54 means that the clamping force transmission element 17 does not hinder the movement of the detection device 47 relative to the retaining element 15.

[0065] The through-opening 42, in particular through-bore 42, in the information carrier 4 can also be made on site during mounting, if necessary. For example, hole punch pliers can be used to punch a small hole 42 to form the through-opening 42 in the information carrier 4. Then the clamping force transmission means 17, starting with its end 32, can be fed through the through-opening 42. At the end 31, the head 41 then hooks on the information carrier 4.

[0066] FIG. 4A shows a detection device 47 of a shaft information system 1 having side pieces 51, 52, for guiding the information carrier 4 in a schematic detail diagram corresponding to a second possible design. In this exemplary embodiment, an abutting face 60 is formed on the side piece 51. An abutting face 61 is also formed on the side piece 52. In this case, the side pieces 51, 52 are designed as separate side pieces 51, 52 and can thus be separated from each other, in principle. In the mounted state, in which the guiding structure 50, together with the side pieces 51, 52, is inserted into the receptacle 53, the abutting faces 60, 61 of the side pieces 51, 52 bear against each other.

[0067] FIG. 4B shows the side pieces 51, 52 of the detection device 47 shown in FIG. 4A during a mounting process for inserting the information carrier 4 into the detection device 47. In this case, the side pieces 51, 52 are separated from each other during the mounting process, so that the information carrier 4 can be inserted into the side pieces 51, 52, which are then joined together again. The side pieces 51, 52 are placed end to end at a rear 62 and then inserted into the receptacle 53.

[0068] FIG. 5A shows a detection device 47 of a shaft information system 1 having side pieces 51, 52, for guiding the information carrier 4 in a schematic detail diagram corresponding to a third possible design. In this design, the side pieces 51, 52 of the guiding structure 50 are designed as side pieces 51, 52 which are separate from each other. The side pieces 51, 52 of the guiding structure 50 are also separated from each other when they are inserted into the receptacle 53. The positioning of the side pieces 51, 52 takes place in an interlocking manner. For example, noses 63, 64 are formed on the receptacle 53, which engage in corresponding grooves 65, 66 in the side pieces 51, 52 when in the mounted state. A rear wall 67 can be provided, depending on the design of the detection device 47. The rear wall 67 is in this case inserted into the receptacle 53 as a separate component. Suitable openings can then be formed in the rear wall 67, in case, for example, the information of the information carrier 4 should be read optically by means of a read device 58.

[0069] FIG. 5B shows the side pieces 51, 52 of the detection device 47 shown in FIG. 5A during a mounting process for inserting the information carrier 4 into the detection device 47. In this case, at least one of the side pieces 51, 52 is removed from the receptacle 53. The information carrier 4 can thereby be inserted into the detection device 47. The at least one removed side piece 51, 52, in this case the side piece 52, is then inserted back into the receptacle 53. The two separated side pieces 51, 52 in this exemplary embodiment can thus be inserted into the receptacle 53 of the detection device 47 separately from each other and in an interlocking manner.

[0070] FIG. 6 shows a retaining element 15 of a device 3 for retaining an information carrier 4 in a schematic sectional diagram corresponding to a further exemplary embodiment of the invention, wherein the information carrier 4 is retained by a magnetic force F. In this exemplary embodiment, the retaining element 15 has a rear receptacle 70 into which a magnetic element 71 is inserted. The magnetic element 71 is fixed in the rear receptacle 70 in a suitable manner. In this exemplary embodiment, at least one bridge 72 is provided to prevent direct contact between the information carrier 4 and the magnetic element 71. The information carrier 4 is permanently magnetized and/or magnetizable by the magnetic element 71, that is, ferromagnetic, at least at the point 8. The magnitude of the magnetic force F is predefined so as to ensure that the information carrier 4 returns to the contact regions 38, 39 of the retaining element 15 after passing through the detection device 47, even if the information carrier 4 is lifted off from the contact regions 38, 39. As long as the information is stored on the information carrier 4 magnetically, magnetic shielding within a limited region can be implemented, if necessary, by a suitably designed bridge 72.

[0071] FIG. 7 shows the elevator system 2 having a shaft information system 1 in a schematic diagram to explain the invention. The elevator system 2 has the elevator car 80, which is suspended from supporting means 81. The device 3 is connected to the rail 5. The information carrier 4 is fastened in the region of a shaft floor 83 of the elevator shaft 6 via a fastening element 82. In the tensioned state, the information carrier 4 extends at least substantially over a height 84 of the elevator shaft 6. The height 84 can be divided one or more times by the device 3 and by any other correspondingly designed devices. This produces partial heights 85A, 85B, at the ends of which fastening or retaining points are implemented. For example, a height 84 of 200 m can be divided into partial heights 85A, 85B and further partial heights of 50 m each. Three devices 3 are needed for this.

[0072] The guidance of the information carrier 4 in the detection device 47 along the extent 9 of the information carrier 4 is also illustrated. Here, the information carrier 4 is deflected somewhat out of the predefined extent 9. This deflection occurs within the partial heights 85A, 85B and when passing through a device 3. In the situation shown, the detection device 47 is still far enough away from the device 3 that the deflection of the information carrier 4 out of the predefined extent 9 only has an effect in the partial height 85A.

[0073] The detection device 47 allows additional guidance of the information carrier 4 so that, for example, the information carrier 4 does not twist. The read device 58 can then be guided close to the information carrier 4 to allow fault-free and precise reading of the information. The information carrier 4 is then stabilized and guided in the reading region, inter alia.

[0074] Possible excitations which can excite the information carrier 4 to vibrate are prevented or at least damped owing to the provided device 3. This prevents the information carrier 4 striking adjacent devices and avoids noise. Moreover, this has a favorable effect on fault-free and precise reading of the information.

[0075] Since the presented method can use any number of devices 3 in practice, it is possible to use it even with large building heights and thus large heights 84 of the elevator shaft 6.

[0076] The invention is not limited to the described exemplary embodiments and designs. For instance, the clamping element 16 can also be in the form of a spring or tension spring, which is connected to the information carrier 4 directly or indirectly by means of the clamping force transmission means 17 at one end and to the connection piece 18 at the other end. The connecting parts are then designed such that the spring pulls the information carrier 4 to the retaining element 15.

[0077] In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
