[0003] Height-adjustable device mount for vehicle rails

[0004] TECHNICAL AREA OF INVENTION

[0005] 5

[0006] The invention relates to a device holder for the height-adjustable mounting of devices, in particular electronic devices such as wheel sensors, on vehicle rails.

[0007] BACKGROUND OF THE INVENTION

[0008] For various reasons, there is a need to attach devices, especially electronic devices such as sensors and switching devices, to vehicle tracks, such as railway tracks, for which appropriate device holders are required.

[0009] Numerous device mounting systems for attaching devices to vehicle rails (hereinafter also referred to as rails) have already been proposed. These can be roughly categorized according to whether it is necessary to drill through a rail section, usually the so-called rail web, to attach the device mounting system, or whether they are clamped to a rail section, usually the so-called rail foot, without drilling. Device mounting systems of the first type are known, for example, from DE 32 34 651 A1, DE 199 15 598 A1 and DE 102013 0125 084 B4. Device holders of the second type are known, for example, from DE 695 741 C1, EP 1 960 603 B1 and DE 974202 C1, wherein, according to all three documents, device holders are clamped to the rail base and wherein the last two documents show height-adjustable device holders.

[0010] The most common and safety-related application of such device mounts is the installation of so-called wheel sensors, also known as track switches, although the invention is not limited to such electronic devices. 5 D / PINUXR-044-PC

[0011] - 2 -

[0012] Wheel sensors are regularly used to monitor track sections to determine whether a rail vehicle, especially a train, is present. This is achieved, for example, by inductively detecting how many wheels (and thus axles; in railway engineering, this is generally referred to as axle counting and axle counting circuits) are present.

[0013] 5 spoken) sensors that are located on the rails at the beginning and end of a monitored track section, in order to conclude whether another rail vehicle is allowed to enter the track section or not.

[0014] For such sensors and other devices to function correctly, their precise positioning on a rail is crucial, especially adjusting the distance between the top of the device and the top of the rail's running surface, commonly referred to as height adjustment. The problem of accurate height adjustment doesn't only arise during the initial installation of such a device on a rail. Wear and subsequent modifications often significantly erode the running surface, considerably reducing the distance between the top of the device and the top of the running surface. This can render certain settings, such as device calibration, inaccurate, potentially leading to erroneous measurements, for example, with sensors. In extreme cases, a device can even be damaged by a passing wheel.

[0015] Height adjustment is by no means trivial in the work environment in question. Equipment mounts must be able to withstand loads of several hundred, sometimes even over a thousand grams, which can occur when a very fast train passes over a section of track to which an equipment mount is attached. In addition to the mechanical loads, thermal loads are also regularly present. Accordingly, the equipment mounts are dimensioned and typically made of high-density materials, making them relatively heavy compared to the equipment they are meant to hold.

[0016] To at least partially solve the problem of height adjustment, height-adjustable device holders are known from the aforementioned publications EP 1 960603 B1 and DE 974202 C1, each comprising a base holder with two clamping jaws to be fixed to a 5 vehicle rail and a D / PINUXR-044-PC

[0017] - 3 - comprise an adapter plate, which can be fixed to the base bracket in various relative positions to the base bracket, for mounting a device to be attached to the vehicle rail. The solution known from EP 1 960603 B1 allows the base bracket, which is usually very heavy, to be fixed to the rail first, and then

[0018] 5. The adapter plate is fixed to the base bracket at a specific mounting height, whereas in the solution known from DE 974202 C1, a single clamping screw clamps both the adapter plate against one of the two clamping jaws of the base bracket and the two clamping jaws against the rail foot. It should be noted at this point that the common term "adapter plate" does not necessarily refer to an actual plate-shaped (flat) component. Rather, the adapter plate can have various suitable designs and, for example, be shaped like a T-beam or a box. By using different adapter plates, different devices can be attached to one and the same base bracket. Therefore, in this text, the term "adapter plate" does not refer to the precise three-dimensional design of the component so designated, but to its function.

[0019] Although the known adapter plates can be fixed to a base bracket in various relative positions, thus enabling the desired height adjustment, setting a desired height (i.e., the distance between the device, typically the top of the device, and the rail, typically the top of the rail's running surface) is regularly very complex: due to the high loads to which device brackets of the type in question are subjected, fasteners such as large clamping screws are used to fix the adapter plates to the base brackets, which are characterized precisely by the fact that they do not come loose easily.

[0020] From the publications EP 1 960603 B1, EP 4 147 941 A1 and US 2021 0347395 A1, device holders are known, each with a base holder and an adapter plate for the height-adjustable mounting of devices, in particular sensors, on vehicle rails, in which the mutually facing surfaces of the base holder and adapter plate are profiled complementarily (typically with a triangular grid) so that after tightening the clamping screws in the D / PINUXR-044-PC

[0021] - 4 -

[0022] The vertical direction should not only achieve a purely force-fit connection but also a form-fit connection. If the clamping screws are only lightly tightened in such a design, the adapter plate and base bracket will tilt relative to each other under the influence of gravity, which can lead to...

[0023] 5. The adapter plate and base mount remain in a temporary position relative to each other. While this can facilitate initial alignment, this connection is not reliable and, moreover, imprecise due to the tilting. To actually test whether, for example, inductive wheel sensors are correctly positioned, the adapter plate and base mount must first be fully fixed before the positioning can be tested.

[0024] If the positioning of the device to be installed is incorrect, the fixing of the adapter plate and base bracket must be laboriously loosened, the adapter plate repositioned, and then fully fixed again before a new test can be carried out. This procedure is not only tedious but also time-consuming and therefore associated with high costs: for example, if corresponding wheel sensors need to be realigned during maintenance work, this typically cannot be done quickly during operation, but rather a corresponding section of track must be taken out of service for a certain period and trains must be rerouted accordingly. The work on the device brackets is typically carried out by hand and is not only physically demanding but also requires maintenance personnel to carry appropriately sized and therefore heavy tools, which poses an additional challenge in remote sections of track.

[0025] BRIEF SUMMARY OF THE INVENTION

[0026] The invention is based on the objective of providing a height-adjustable device holder in which the height adjustment is significantly simplified.

[0027] The problem is solved by a device holder with the features of claim 1. Dependent claims 17 and 18 relate to a device, 5 in particular an electronic device, with a D / PINUXR-044-PC according to the invention.

[0028] - 5 -

[0029] Device holder or arrangement comprising a vehicle rail and a device, in particular an electronic device, attached to the vehicle rail by means of a device holder according to the invention.

[0030] 5 A height-adjustable device holder for vehicle rails according to the invention comprises a base holder to be fixed to a vehicle rail, an adapter plate to be fixed to the base holder in various relative positions to the same for holding a device to be attached to the vehicle rail, means for fixing the adapter plate to the base holder in a fixed manner and means separate from the means for fixing in a fixed manner for provisionally determining the relative position of the adapter plate and the base holder.

[0031] Thanks to such means – separate from the means for permanent fixing – for provisionally determining the relative position of the adapter plate and the base bracket, aligning a device on a rail is significantly simplified. This is because various height settings can now be tested before tightening means such as clamping screws for permanent attachment of the device to the rail, before the adapter plate is fixed to the base bracket in a known manner, ensuring that the fixation can withstand the loads occurring during operation. In other words, a "quick adjustment" is separated from the final (releasable) fixing.This separation significantly simplifies and, above all, accelerates the entire process of positioning a device to be attached to a rail using the device holder according to the invention, which not only saves forces5 but also contributes massively to cost reduction through the time savings made possible, and is advantageous not only when initially attaching a device, but especially when repositioning it during maintenance work.

[0032] In a preferred embodiment, the means for the operationally secure fixing of the adapter plate and base mount comprise at least one clamping screw which is guided in at least one elongated hole of the base mount or the adapter plate in a height-adjustable manner. In such an embodiment, the means for the temporary fixing of the relative position of the adapter plate and base mount can then be configured to determine the position of the at least one D / PINUXR-044-PC

[0033] - 6 -

[0034] The clamping screw is to be fixed in the at least one elongated hole. It should be noted here that the at least one clamping screw can also serve to attach the base bracket to the rail, so that the at least one clamping screw, when tightened, acts as a

[0035] 5. It has a dual function, fixing both the base bracket to the rail and the adapter plate to the base bracket. However, since this is irrelevant for the height adjustment according to the invention, it can be disregarded here whether the base bracket is first fixed to the rail and then the adapter plate is fixed to the base bracket with separate fasteners, or whether one or more clamping screws fulfill the aforementioned dual function.

[0036] In a further preferred embodiment, the means for provisionally fixing the relative position of the adapter plate and the base mount comprise a grid and a counterpart engaging in the grid to define predetermined relative positions of the adapter plate and the base mount. Such a design can contribute to particularly quick and easy positioning of a device on a rail, in which the desired distance (the "height") can be set in predefined steps, the grid naturally having suitable distances between the individual grid positions for the respective application.

[0037] If the base bracket and adapter plate are fixed by at least one clamping screw, the position of the at least one clamping screw in the elongated hole can advantageously be determined by at least one clamping screw opening in the counterpart 5 or the indexing mechanism. Such a clamping screw opening can advantageously be dimensioned such that it guides and holds an inserted clamping screw in such a way that the device bracket can be provided partially pre-assembled.

[0038] In a preferred embodiment, the at least one clamping screw opening is arranged between the adapter plate and the base bracket in the intended assembly state of the device holder. This allows locking elements such as snap rings, locking washers, wedge washers, etc., to be inserted directly between the clamping screw head and, depending on the mounting direction of the clamping screw, the adapter plate or the D / PINUXR-044-PC.

[0039] - 7 -

[0040] The base bracket should be arranged so that the element containing at least one clamping screw opening does not impair the function of the locking devices. The same applies, if provided, to a nut interacting with the clamping screw, in which case corresponding locking devices should also be used.

[0041] 5 directly on the nut and, depending on the placement of the clamping screw, either on the base bracket or the adapter plate.

[0042] In another preferred embodiment, the indexing has a sawtooth profile with a preferred direction in which the engaging counterpart can be moved without being positively locked. Typically, the preferred direction is selected such that, for positioning a device, it can simply be moved without tools from a distant position closer and closer to the running surface, where it then remains in the respective indexing positions in which the counterpart positively engages the indexing.5.

[0043] In another preferred embodiment, the counterpart is formed by a spring-loaded sheet, wherein the indexing or the spring-loaded sheet is slidably attached to the base mount or the adapter plate. Such a design enables reliable temporary fixing of the adapter plate relative to the base mount with minimal weight of the necessary components. It should be expressly noted here that the spring-loaded sheet need not be a rolled metal product, as the term "sheet" might suggest. Rather, the "spring-loaded sheet" can also be made of other suitable materials, in particular appropriate plastics. However, since components of the type in question are typically made of metal, at least currently, the term "spring-loaded sheet" has been used in the trade and is therefore to be understood in this text in a functional sense and not as restrictive to the material.

[0044] If such a spring plate is provided, according to a further preferred embodiment it can have an engagement section that engages in the indexing and an actuating section for removing the engagement section from the indexing. This advantageously eliminates the need for five separate components for height adjustment, as the D / PINUXR-044-PC

[0045] - 8 -

[0046] The engagement section is easily moved out of the detent, for example by pulling on the actuating section. Advantageously, the actuating section is designed so that, in the intended mounting state of the device holder on a rail, it is actuated from the side of the device holder facing away from the rail.

[0047] 5 can be used, which allows for particularly easy handling of the device holder.

[0048] In another preferred embodiment, the spring plate has a mounting section with two undercuts, which can be guided through a receiving opening in the base bracket or the adapter plate such that, in the intended assembly state of the device holder, the undercuts rest against an edge of the receiving opening. This advantageously allows the spring plate to be attached to the adapter plate or the base bracket without any additional separate fasteners, ensuring that it is held securely during work with the device holder, particularly when positioning a device to be mounted on a rail. By appropriately designing the receiving opening, it is also possible, if desired, to easily arrange the spring plate so that it can be slidably mounted on the adapter plate or the base bracket.

[0049] In another preferred embodiment, the engagement section and the actuating section are formed on the fastening section of the spring sheet, for example by punching and bending, if the spring sheet is actually a sheet, so that the spring sheet can be multifunctional at low weight5.

[0050] The grid pattern can be formed on the base plate or the adapter plate. In a preferred embodiment, however, the grid pattern is provided by a grid plate supported on the base plate or the adapter plate, which can offer manufacturing and weight advantages. Generally, it is simpler to manufacture a grid plate made of, for example, plastic, than to provide the base plate or the adapter plate, which is typically made of metal, with a grid pattern. Furthermore, the grid plate can help to attach a component, such as the spring plate, to the adapter plate or the base plate: Is the aforementioned receiving opening for a mounting section D / PINUXR-044-PC

[0051] - 9 - a spring plate is provided, so the grid plate can be arranged in the intended assembly state of the device holder between the receiving opening and the fastening section and thus contribute on the one hand to securing the spring plate, while conversely the spring plate secures the grid plate against

[0052] 5. The receiving opening is clamped and secured.

[0053] In another preferred embodiment, alignment openings are provided in the component containing the receiving opening, i.e., in the base holder or the adapter plate, and alignment projections that are at least partially complementary to these openings are provided on the grid plate. This facilitates the positioning and mounting of the grid plate, which can also be, for example, glued in place.

[0054] In another preferred embodiment, at least one elongated hole and, if present, the receiving opening are provided in the adapter plate. This not only offers manufacturing advantages but also advantageously contributes to reducing the weight of the adapter plate, which is essentially an undamped mass, and thus the forces acting on the base mount.

[0055] Further details and advantages of the invention will become apparent from the following purely exemplary and non-limiting description of embodiments in conjunction with the drawing comprising six figures. 5

[0061] Fig. 4 shows a perspective view of a spring sheet according to the invention.

[0062] Fig. 5 shows a perspective view of a grid plate according to the invention.

[0063] Fig. 6 shows a partially schematic representation of a step in the assembly of the device holder according to the invention. 5 DESCRIPTION OF PREFERRED EMBODY FORMS

[0064] Figures 1 to 6 show, in a more or less schematic form, a device holder according to the invention and its parts in various assembly and application stages.

[0065] Fig. 1 schematically shows a section of a rail, designated in its entirety by 10, together with a device holder according to the invention arranged thereon, comprising an electronic device designated in its entirety by 12. The device is a typical wheel sensor with a sensor plate 14 and a sensor housing 16.

[0066] The section of rail 10 shown is a typical railway rail with a rail head 18, the upper side of which forms a running surface 20, a rail web 22 and a rail foot 24.

[0067] In the illustrated embodiment of a device holder according to the invention, a base holder 26 engages the rail foot 24. Like a claw, it clamps the rail foot 24, for which purpose the part of the base holder 26 visible in Fig. 1 is secured against a corresponding counterpart 5 on the opposite side of the rail foot by means of one or more clamping screws.

[0068] - 11 -

[0069] 24 is tensioned. The device holder shown is therefore one of those that does not require drilling through the rail 10. However, the height adjustment according to the invention is not limited to such types of device holders. The basic position can theoretically also be adjusted on the rail web 22 via

[0070] 5 corresponding holes and corresponding retaining screws are used.

[0071] The device holder further comprises an adapter plate 28, wherein, in this embodiment, the adapter plate 28 and the base holder 26 are fixed by means of two clamping screws which are "height-adjustable" in two elongated holes 30. To clarify the design of the adapter plate 28, the clamping screws, which actually pass through the two elongated holes 30 in the adapter plate 28 to fix the adapter plate 28 relative to the base holder 26, as well as the fastening screws, which actually pass through the two mounting openings 32 5 to attach the device 12 to the adapter plate 28, have been omitted from the schematic representation in Fig. 1. The term "height-adjustable" refers to the fact that by sliding the adapter plate along the elongated holes 30, the distance of the device 12 to the running surface of the rail 10, and thus the height of the device 12 above the rail foot 24, can be changed.

[0072] Figures 2 and 3 show the adapter plate 28, along with a spring plate 34 and a grid plate 36, in perspective and partially schematic form, once obliquely from the front (i.e., viewed in the intended assembly state towards a rail) and once obliquely from the rear (i.e., viewed from the direction of the rail).5 They include mounting elements such as clamping screws 38 for fixing the adapter plate 28 to the base and fastening screws 40 for attaching a device to the adapter plate 28. As in Figure 6, the screws are shown only schematically, i.e., without threads. In reality, the cylindrical sections of the screws 38 and 40 are provided with external threads.Furthermore, the clamping screws 38 are shown here in a significantly shortened form, at least when they fulfill the dual function described above and are intended not only to fix the adapter plate 28 to the base bracket, but also to pre-tension a base bracket consisting, for example, of two clamping jaws against the rail. 5 D / PINUXR-044-PC.

[0073] - 12 -

[0074] The clamping screws 38, which pass through the elongated holes 30, can theoretically be screwed into receiving openings in the base bracket that have corresponding internal threads. Preferably, however, the receiving openings are designed as guide openings without threads, in which case

[0075] Five corresponding nuts are provided on the side of the base bracket facing away from the adapter plate. As mentioned above, the clamping screws can serve either to fix the adapter plate to the base bracket or to fix the base bracket to the rail, for which purpose they may, for example, be designed to clamp two jaws of a corresponding base bracket against each other.

[0076] In the sense of a kinematic reversal, the design can also be such that the elongated holes are located in the basic position and the receiving openings for the clamping screws 38 are arranged in the adapter plate.5 Likewise, it is essentially irrelevant whether the means for provisionally fixing the relative position of the adapter plate and the base mount, described in detail below, are arranged on the adapter plate or the basic mount. However, for manufacturing and handling reasons, the arrangement shown in the figures has proven particularly advantageous.

[0077] In this embodiment, the means for provisionally fixing the relative position of adapter plate 28 and base bracket (26 in Fig. 1) are designed to fix the position of the clamping screws 38 in the elongated holes 30 and comprise the spring plate 34 and the grid plate 36, which, according to the invention, makes it possible to decouple the positioning of the adapter plate 28 relative to the base bracket, and thus the height adjustment of a device attached or to be attached to the adapter plate relative to the rail, from the fixing of the adapter plate 28 to the base bracket, so that, advantageously, fixing only needs to take place when the height is correctly set.

[0078] In the illustrated embodiment, the grid plate 36 provides a grid (42 in Fig. 5), while the spring plate 34, more precisely an engagement section (44 in Fig. 4) formed on the spring plate 34, forms a counterpart that engages in the grid to define predetermined relative positions of the adapter plate 28 and the base holder 5. In principle, such a grid can also be D / PINUXR-044-PC

[0079] - 13 - can be formed directly on the adapter plate 28 or, depending on the design, also on the base mount. However, providing the grid by means of a separate component has several advantages, which will be discussed below.

[0080] 5

[0081] As can be clearly seen in Fig. 4, the spring plate 34, which in this embodiment acts as a counterpart to the indexing, has two clamping screw openings 48 formed in tab sections 46, which are advantageously each adapted to the outer diameter of the clamping screws in such a way that they guide and hold inserted clamping screws so that the adapter plate can be provided pre-assembled, so that a fitter on site does not have to first equip the adapter plate with clamping screws.

[0082] When the adapter plate 28 shown in Figures 2 and 3 is attached to a base bracket 5, the tab sections 46 and thus the clamping screw openings 48 of the spring plate 34 shown in Figure 4 are located between the adapter plate and the base bracket, so that locking elements 50 such as snap rings, locking washers, wedge lock washers, etc., bear directly against the adapter plate 28 and can exert their full locking effect against unintentional loosening of the clamping screws 38. As indicated, for example, in Figure 6, a washer 51 can be arranged between the screw head and the locking element 50; however, this is not desirable when the locking elements are locking washers. Figure 4 clearly shows that in this embodiment, the spring plate 34 has a mounting section 52 with two undercuts 54, which is thus connected by a receiving opening (56 in Figure 4).2) can be guided through the adapter plate so that the undercuts 54 rest against an edge of the receiving opening in the intended assembly state. This advantageously allows the spring plate to be attached to the adapter plate without any further separate fastening means, so that it is held securely during work with the device holder, in particular when positioning a device to be mounted on a rail, wherein the grid plate 36, as shown in Fig. 2, is pushed through a slot formed between the 5 fastening section 54 and the adapter plate 28 in this embodiment, D / PINUXR-044-PC.

[0083] - 14 - so that spring plate 34 and grid plate 36 secure each other to the adapter plate 28.

[0084] As can also be seen in Fig. 4, in this embodiment the

[0085] In the intended mounting state, the edge of the mounting section 52 facing the grid plate has an engagement section 44 that engages in the grid of the grid plate, while the side of the mounting section 52 opposite the engagement section 44 is bent for easier handling and has an actuating section 58. The mounting section 52 is connected to the rest of the spring plate 34 via two spring bars 60, so that the engagement section 44 can be removed from the grid by pulling on the actuating section 58, and thus the relative position of the adapter plate can also be adjusted against the preferred direction described below. As can be seen from Fig. 2, in the intended mounting state, the actuating section 58 is located on the side of the adapter plate 28 facing away from one of the rails and can therefore be easily actuated.

[0086] Fig. 5 shows in detail the grid plate 36 provided in this embodiment. It has two identical grids 42, the individual locking projections 62 of which, for the sake of clarity, only some are provided with reference numerals, are designed such that the grids 42 each have a sawtooth profile with a preferred direction 64 indicated by an arrow, in which an engaging counterpart, in the illustrated embodiment the spring plate, can be moved without being positively locked.

[0087] The grid plate 36 also has a retaining section 66 and a projection 68, which serve to align and support the grid plate 36 in the receiving opening (56 in Fig. 2).

[0088] Fig. 6 shows a highly schematic representation of a step in the assembly of the device holder according to the invention, namely the arrangement of the spring plate, of which only the fastening section 52 with engagement section and actuating section as well as part of one of the spring bars are visible here, on an adapter plate 28. To clarify the later installation situation, the D / PINUXR-044-PC

[0089] - 15 -

[0090] Clamping screws 38 are shown, although these are actually only inserted after the spring plate has been correctly positioned in the receiving opening 56 through the adapter plate and the clamping screw openings (48 in Fig. 4) which are then positioned behind the elongated holes. Mounting section 52 and receiving opening 56 are thus

[0091] Figure 5 is dimensioned so that the fastening section 52 can only be guided obliquely through the receiving opening 56. Once the clamping screw openings are positioned behind the elongated holes, the spring plate is supported by the undercuts described above (54 in Fig. 4) against the corresponding edge regions of the receiving opening 56, and the spring plate can be moved upwards and downwards in the receiving opening, parallel to the elongated holes (30 in Fig. 1). Once the clamping screws are guided through the elongated holes and the clamping screw openings, a movement of the spring plate causes a movement of the clamping screws.5. When the spring plate is correctly positioned in the receiving opening 56, the grid plate 36 is pushed from below through the slot formed between the mounting section 52 and the adapter plate 28 and positioned in the receiving opening 56. The projection 68 then rests against an upper edge 70 of the receiving opening 56, while the retaining section 66 rests against the adapter plate 28 below the receiving opening 56. The spring plate then clamps the grid plate 36 against the adapter plate 28, while conversely, the grid plate 36 holds the spring plate correctly positioned in the receiving opening 56. After the clamping screws 38 are inserted, this positioning is further supported by them.

[0092] For easy positioning and support of the grid plate 36 on the adapter plate 28, this embodiment provides two alignment openings 72 in the adapter plate 28, which interact with alignment projections on the grid plate 36 (not visible here) that are at least partially complementary to the alignment openings. Alternatively or additionally, the grid plate 36 can also be glued to the adapter plate 28, for which purpose, for example, a self-adhesive strip can be provided on the side of the retaining section 66 facing the adapter plate 28. D / PINUXR-044-PC

[0093] - 16 -

[0094] When fully assembled, the grid plate 36 and the spring plate are movable relative to each other parallel to the elongated holes, but are held firmly in predefined detent positions, which then means that the adapter plate can also be moved relative to the base mount if the clamping screws 38 are not tightened.

[0095] 5 are tightened so that various relative positions of the adapter plate and base bracket – and thus of the device to be mounted and the rail – can be easily and quickly adjusted. It can then be tested whether the respective position is optimal, i.e., whether the device to be mounted is in the desired position relative to the rail. Only when an optimal position has been found are the clamping screws 38 tightened securely and the adapter plate 28 fixed relative to the base bracket so that the set position is maintained even under the high loads that occur during operation. 5
