Description

[0001] The invention relates to a mounting device for a column-shaped electrical or electronic functional component, in particular a charging station for an electric vehicle, a parking meter, a parking ticket machine or a lamp.

[0002] Functional components of the type mentioned above are often set up free-standing in publicly accessible or private outdoor facilities such as parking spaces for motor vehicles, driveways or sidewalks; this is often the case in groups of several similar functional components. Such functional components are usually each mounted on their own concrete foundation. The cabling, i.e. the supply of power lines and, if applicable, signal lines to the respective functional component, is usually carried out via underground cables. The installation of such functional components therefore requires earthworks, the cost of which is often on the same order of magnitude as the cost of manufacturing and assembling the functional component. In addition, repairing, modifying or expanding a system comprising one or more of these functional components is usually associated with a great deal of expense.

[0003] The invention is based on the object of enabling a comparatively simple and inexpensive installation of a functional component of the type described above and of a system comprising one or more such functional components.

[0004] This object is achieved according to the invention by a mounting device for a column-shaped electrical or electronic functional component, in particular a charging station for an electric vehicle, a parking meter, a parking ticket machine or a light, having the features of claim 1. The mounting device comprises a base plate which is screwed to a foot of the functional component or is integrally connected (e.g. welded), and a channel-shaped component which serves on the one hand to fasten the base plate and on the other hand to form a cable duct. The channel-shaped component comprises a bottom wall and two side walls formed on the bottom wall, wherein an interior space is formed between the side walls which is open towards an upper side opposite the bottom wall. A side frame which is L-shaped in cross section is fastened to both side walls in the region of a free end of the respective side wall opposite the bottom wall.Each of the two side frames rests with a horizontal leg on the free end of the respective side wall of the channel-shaped component, and projects towards the top with a vertical leg. The side frames are arranged in such a way that the base plate can be inserted between the vertical legs and, when inserted, rests on the horizontal legs. A row of holes is drilled into the horizontal leg of each side frame to accommodate fastening screws for screwing the base plate to the channel-shaped component. The side walls of the channel-shaped component each have a cavity below each hole to accommodate a threaded piece. When assembled, the base plate is screwed directly to the side frames using the fastening screws and the threaded pieces inserted in the cavities.

[0005] Preferably, the holes in the horizontal leg of the associated side frame are arranged at regular intervals, i.e., at the same distance from the next hole. However, within the scope of the invention, the holes in each row can also be arranged at (particularly slightly) different distances from one another.

[0006] According to the invention, the base plate is screwed directly to the side frames of the trough-shaped component, which enables particularly straightforward installation of the functional component. Since the functional component is mounted on the trough-shaped component, which can also be used as a cable duct for supplying power and signal lines, the conventionally required effort for constructing foundations and laying underground cables is eliminated or at least significantly reduced. To enable flexible arrangement of the functional component relative to the trough-shaped component, the base plate, in one expedient embodiment, has two elongated holes, one of which is aligned with one of the two rows of holes when the base plate is inserted between the side frames.The elongated holes are arranged in such a way that the base plate can be screwed or bolted through one elongated hole and one hole in each of the corresponding rows of holes. The base plate can be moved relative to the channel-shaped component along the elongated holes until a corresponding screw connection is tightened.

[0007] In a preferred alternative embodiment, the base plate has two rows, each with (at least) two elongated holes arranged next to one another in the longitudinal direction. The elongated holes are arranged such that each row of elongated holes is aligned with an associated row of bores when the base plate is inserted between the side frames. The elongated holes are therefore in turn arranged such that the base plate can be screwed or bolted through each elongated hole and each bore of the associated row of bores. If each of the two rows of elongated holes is formed from two elongated holes each, the base plate can be screwed or bolted to the channel-shaped component at four points. The base plate is in turn movable relative to the channel-shaped component along the elongated holes until a corresponding screw connection is firmly tightened.

[0008] If the holes in each of the two rows are arranged at equal distances from one another, each elongated hole in a preferred embodiment has a longitudinal extension that corresponds at least to the distance between the holes in the respective row. If, for example, the holes in each row are spaced 100 mm apart from the adjacent hole, each elongated hole preferably also has a longitudinal extension of at least 100 mm. If, on the other hand, the holes in the two rows are arranged at unequal distances from one another, each elongated hole in a preferred embodiment has a longitudinal extension that corresponds at least to the greatest distance between two adjacent holes in the associated row of holes. If, for example, the greatest distance between two adjacent holes is 120 mm, the elongated holes in the base plate also have a longitudinal extension of at least 120 mm.This dimensioning of the elongated holes ensures that the base plate can be screwed to the channel-shaped component at any position along its longitudinal direction.

[0009] In an advantageous embodiment of the invention, the threaded pieces to which the base plate is screwed are each formed by a threaded rivet inserted into the corresponding hole. The threaded rivet is pressed into the hole and thus held captively to the side frame even before the screw connection is made.

[0010] In a particularly simple alternative embodiment of the invention, the threaded pieces are each formed by a nut, in particular a square nut, which is inserted into the associated cavity and which is dimensioned such that it cants in the cavity when the screw connection is produced.

[0011] A particular embodiment of the invention is the channel-shaped component described above which is used in the assembly device.

[0012] In the following, exemplary embodiments of the invention are explained in more detail with reference to a drawing. In the drawings: Fig. 1 shows a perspective view of a channel-shaped component of a mounting device for a column-shaped functional component, wherein the channel-shaped component also serves as a cable duct, and wherein the channel-shaped component has a bottom wall and two side walls, wherein a side frame with an L-shaped cross section is attached to the free ends of the side walls facing away from the bottom wall, Fig. 2 in representation according to Fig. 1 the assembly device, which is essentially formed by the channel-shaped component and a base plate inserted between the side frames, Fig. 3 and Fig. 4 in a cross-section the channel-shaped component according to Fig. 1 with differently designed threaded pieces for screwing the base plate to the channel-shaped component, Fig. 5 in perspective view with a view from above the channel-shaped component according to Fig. 1 with the base plate mounted thereon and the base of an electrical or electronic functional component (here a charging station for an electric vehicle) mounted on the base plate, and Fig. 6 in perspective view with a view obliquely from above the charging station mounted on the trough-shaped component by means of the base plate.

[0013] Corresponding parts are always provided with the same reference symbols in all figures.

[0014] Fig. 1 shows a trough-shaped component primarily intended for forming a cable duct and therefore referred to as a cable duct piece 2, without excluding other possible uses. The cable duct piece 2 is essentially formed from a base wall 4 and two side walls 6 and 8 formed thereon. The base wall 4 and side walls 6 and 8 form a one-piece body with a U-shaped cross-section, preferably made of concrete or a (natural or artificial) stone material, e.g., lime-sandstone or brick. Between the side walls 6 and 8, an interior space 10 is formed, which is open towards the longitudinal side of the cable duct piece 2 opposite the base wall 4.

[0015] In the intended installation position, the cable duct section 2 is mounted with the open long side facing upwards, namely in particular laid on a cement bed in the subsurface so that the open long side is approximately flush with the surrounding surface (e.g. the floor covering of a path or parking lot). This open long side of the cable duct section 2 is therefore also referred to as the "top side" 12 or "top" - regardless of the actual orientation of the cable duct section 2 in the surrounding space. The opposite side of the cable duct section 2, occupied by the floor wall 4, is correspondingly referred to as the "bottom side" 14 or "bottom" - also regardless of the actual orientation of the cable duct section 2 in the surrounding space.Furthermore, in this sense, one- or two-dimensional structures extending parallel to the bottom wall 4 are referred to as "horizontal," while structures extending perpendicular to the bottom wall 4 are referred to as "vertical." Furthermore, the edges of the side walls 6 and 8 facing away from the bottom wall 4 are also referred to as the free ends of the respective side walls 6 and 8, respectively.

[0016] On these free ends of the two side walls 6 and 8, a side frame 16 or 18 made of sheet steel, each with an L-shaped cross-section, is placed. The two side frames 16, 18 are screwed to the corresponding side wall 6 or 8 or secured with anchors 20 ( Fig. 3 and Fig. 4) is embedded in the material of the side walls 6, 8 and thus anchored to the side walls 6, 8, so that the horizontal leg 22 of each side frame 16, 18 rests on the free end of the associated side wall 6, 8, while a vertical leg 24 of the L-shaped side frame 16 or 18 extends the associated side wall 6, 8 towards the top side 12 and is flush with the respective outer surface of the side wall 6 or 8. The anchors 20, which may be present, have, for example, a pin-like or comb-like shape, wherein in the latter case the anchors 20 advantageously form a form-fitting connection with the surrounding material of the side wall 6 or 8. They are, for example, directly or indirectly welded to the respectively associated side frame 16, 18.

[0017] The horizontal leg 22 of each side frame 16,18 has a row of holes 26. In the example according to Fig. 1, each row has six holes 26. In a practical embodiment, all holes 26 are arranged at the same distance (e.g. 100 mm) from the next hole 26 within the same row. In a Fig. In the alternative arrangement indicated in Figure 1, for example, the three outer bores 26 within each row are arranged at equal distances of, for example, 100 mm from the or each adjacent bore 26, while between the respective middle bores 26 of each row, a slightly larger distance of, for example, 120 mm is formed.

[0018] Below each bore 26, the respective associated side wall 6 or 8 has a cavity 28 open to the free end and to the interior 10. As can be seen from the Fig. 3 and Fig. 4, the walls of the cavities 28 in the example shown here are each lined with a cage 30 (open upwards and inwards), which is connected, in particular welded, to the respective associated side frame 16 or 18. The cavities 28 serve, on the one hand, as water drainage openings for water (in particular rainwater) that collects on the horizontal legs 22 of the side frames 16 and 18 when the cable duct section 2 is installed. Such water can drain through the bores 26 and the underlying cavities 28 into the interior 10 of the cable duct section 2. On the other hand, the cavities 28 serve as a free space for screwing a base plate 32 ( Fig. 2) with the side frames 16 and 18 and thus with the cable duct section 2.

[0019] The Fig. The base plate 32 depicted in Figure 2 together with the cable duct section 2 is preferably made of sheet steel. It has a (particularly substantially rectangular) shape dimensioned such that the base plate 32 can be placed on the top side 12 of the cable duct section 2, so that the base plate 32 rests on the horizontal legs 22 of the side frames 16 and 18 and is flanked laterally by the vertical legs 24.

[0020] In the example according to Fig. 2, the base plate 32 has two rows, each with two longitudinally arranged elongated holes 34. The elongated holes 34 are arranged such that a row of the elongated holes 34 is aligned with a row of the bores 26 when the base plate 32 is in accordance with Fig. 2 is inserted between the side frames 16 and 18. The slots 34 are arranged in such a way that the base plate 32 can be screwed through one slot 34 and one hole 26. Since in the example according to Fig. 2 each of the two rows of elongated holes 34 is formed from two elongated holes 34 each, the base plate 32 is therefore screwed to the cable duct piece 2 at four points as intended.

[0021] For screwing the base plate 32 to the horizontal legs 22, additional threaded pieces are provided which interact with threaded screws (not shown separately) and which can be inserted into the cavities 28 of the cable duct piece 2 so that a threaded hole of the respective threaded piece is aligned with one of the holes 26.

[0022] In a Fig. In the embodiment shown in Figure 3, each of the threaded pieces is formed by a threaded rivet 36, which is inserted with a threaded shank into the respective associated bore 26. The threaded rivets 36 are pressed into the respective bore 26 and are thus held captive on the associated side frame 16 or 18 even before the screw connection is made. When the screw connection is tightened, the threaded shank of the respective threaded rivet 36 is deformed and thus permanently and securely caulked under the respective horizontal leg 22.

[0023] In a Fig. In the alternative design shown in Figure 4, the threaded pieces are each formed by a square nut 38. Each of the square nuts 38 is inserted into the associated cavity 28 via the interior space 10 of the cable duct piece 2. It is dimensioned such that it cants into the cavity 28 when the screw connection is made.

[0024] In a practical embodiment, the square nuts 38 are dimensioned relative to the cavity 28 such that they can be pressed into the cavity 28 and are thus held captively on the cable duct piece 2 even before the screw connection is made. To achieve the same effect, the square nuts 38 are alternatively glued into the cavity 28. Alternatively, the square nuts 38 are loosely inserted into the corresponding cavities 28 for mounting the base plate 32 and are only fixed to the cable duct piece 2 by screwing them together.

[0025] Until a corresponding screw connection is firmly tightened (i.e., as long as the fastening screws are only loosely screwed into the threaded pieces and with some play), the base plate 32 can be moved relative to the cable duct section 2 along the elongated holes 34. The elongated holes 34 are dimensioned such that their longitudinal extension corresponds to the largest distance between adjacent holes 26 within a row (and thus, in the above example, is at least 120 mm). This allows the base plate 32 to be fixed to the cable duct section 2 at any desired position along its longitudinal extension using four screw connections.

[0026] The cable duct piece 2, together with the base plate 32 (as well as the threaded pieces and the associated fastening screws), forms a mounting device 40 for a column-shaped electrical or electronic functional component, which is in particular a charging station 42 for an electric vehicle.

[0027] In the example according to Fig. 5, the mounting device 40 further comprises three threaded pins 44.

[0028] The base plate 32 forms according to Fig. 5 together with the three threaded pins 44 attached thereto and projecting upwards parallel from the base plate 32, a mounting base 46 for mounting the functional component, i.e. charging column 42. The threaded pins 44 are in particular in threaded holes 50 ( Fig. 2) of the base plate 32. Alternatively, they can also be welded, soldered, glued, or otherwise connected to the base plate 32. Each threaded pin 44, in turn, has a height-adjustable spacer (not explicitly shown), formed, for example, by a collar nut screwed onto the threaded pin 44 (or alternatively, by a nut and an associated washer). For height adjustment, the collar nut can be screwed higher or lower on the associated threaded pin 44.

[0029] Charging station 48 is operated according to Fig. 5 and Fig. 6 is formed from a column-shaped housing that supports a charging station 52 at its upper end. The column-shaped housing is formed from a base plate 54 and a vertical profile 56 welded thereto, as well as a front panel 58 and a base panel 60. The front panel 58, the base panel 60, and the vertical profile 56 enclose a closed cavity inside the column-shaped housing, through which power and signal lines are routed to the charging station 52. The cable duct piece 2 serves as part of a cable duct through which the power and signal lines are fed to the charging station 42. The charging station 52 is preferably provided with a permanently connected charging cable 62.

[0030] The Fig. 5 and Fig.6 shows the charging station 42 (or parts thereof) mounted on the cable duct section 2 by means of the base plate 32. In this state, the threaded pins 44 of the mounting base 46 engage through corresponding screw openings in the base plate 54. The charging station 42 is screwed to the base plate 54 using the three threaded pins 44, so that the charging station 42 rests with the base plate 54 on the spacers.

[0031] The three threaded pins 44 are arranged in a (particularly equilateral) triangle with respect to their axes. By adjusting the height of the spacers on the associated threaded pins 44, the charging station 42 can be adjusted in all directions, both in terms of its height and its inclination.

[0032] Areas of the upper side 12 of the cable duct piece 2 that are not covered by the charging column 42 are closed by cover plates 64 that are inserted between the side frames 16 and 18.

[0033] The invention is particularly clear from the exemplary embodiments described above, but is by no means limited to these exemplary embodiments. Rather, further embodiments of the invention can be derived from the claims and the above description.
