Description

Technical Field

[0001] The present disclosure relates to a method and apparatus for providing power to a curb outlet.

[0002] The present disclosure is particularly useful for the installation of a curb-side charging infrastructure in a street where power is provided to the front of a building or a street lamp and needs to be connected to one or more outlets of the curb.

Background Art

[0003] Measures against climate change problems and the shift to fossil fuel-free vehicles require a large investment in infrastructure such as charging points for automobiles.

[0004] In an urban environment, it is particularly difficult to install charging points because public facilities such as water supply and sewerage, drainage, electricity, telephone, IT infrastructure (optical fiber), gas, and district heating are already installed. Such existing facilities may be valid by easement, and therefore, the installation of new facilities needs to be managed from both legal and technical viewpoints so as not to cause confusion.

[0005] Therefore, the installation process of charging points is legally and technically complex and may lead to an increase in cost and lead time.

[0006] Furthermore, such installations are costly, and in particular, excavation work and the like can be a source of greenhouse gas emissions.

[0007] Therefore, there is a need for an installation method of charging points that can suppress complexity and cost.

[0008] WO2021250427 A1, EP2463439A1, and GB2591830A disclose the idea of installing charging points in curb blocks along a curb and further installing charging cables in the curb blocks in order to supply power to a plurality of charging points.

[0009] However, when supplying power from a power source inside or on the side of a building across a sidewalk or the like to a curb block, excavation is still required.

Summary of the Invention

[0010] Therefore, an object of the present disclosure is to reduce the cost of power supply across the area from the power source to the curb.

[0011] The present disclosure is defined by the appended independent claims, and embodiments are described in the appended dependent claims, the following description, and the appended drawings.

[0012] According to a first aspect, a method of installing a socket for charging an electric vehicle at a curb is provided, the curb being spaced from a power source on a residential facade by a sidewalk. The method includes providing a power source on the residential facade, providing a socket at the curb, and connecting a power cable from the power source to the socket. The sidewalk has an outer surface formed of a plurality of paving stones. The power cable extends from the power source to the curb and is installed within a cable channel provided in a plurality of transmission modules, the transmission modules having a thickness substantially the same as the thickness of the paving stones and being installed on the same plane as the paving stones.

[0013] The term "at the curb" is understood to mean that the socket is disposed accessibly for charging an electric vehicle parked along the curb and that there is a portion of the sidewalk where pedestrians can freely pass without substantially stepping over the charging cable.

[0014] The exact distance between the socket and the curb may be varied according to regulations. For example, a minimum distance may be required to prevent damage to the socket by snow removal equipment or the like and / or to ensure space for opening the door of a vehicle. An example of the minimum distance may be about 0.5 m, and an example of the maximum distance may be about 1.5 m.

[0015] The power source may be an electrical cabinet, electrical junction, or electrical box that can be provided on or near the building facade. Alternatively, the power source may be supplied by a cable connected to an electrical cabinet, electrical junction, or electrical box located somewhere in the building.

[0016] The power source is provided on the building facade, particularly at the base of the building facade.

[0017] The curb may be spaced from the building facade by 0.5 to 10 m, particularly about 1 to 5 m, about 2 to 3 m, or about 3 to 5 m, by a sidewalk or a square.

[0018] The sidewalk may be paved with a plurality of paving stones arranged from side to side in a predetermined pattern.

[0019] By placing the cable in a cable channel provided in a module of the same thickness as the paving stone and replacing the necessary number of paving stones with a transmission module having the cable channel, the cable can be installed. Therefore, there is no need to perform excavation, and the risk of interfering with other public facilities installed around it is reduced.

[0020] In the method, the outlet may be provided at a first position along the curb, and the method may include providing a second outlet at a second position along the curb spaced from the first position, arranging a plurality of curb modules extending between the first position and the second position laterally outside the curb, and installing a second power cable in a cable channel provided in the curb module and extending between the first position and the second position.

[0021] By arranging a power cable in a cable channel formed in a curb module installed on the lateral outer side of a curb, typically on the lateral outer side of an existing curb block, it is possible to retroactively supply power along the curb without the need to remove the existing curb, which is particularly beneficial in that the existing curb may include a curb block extending in a vertical and / or horizontal direction with respect to the ground and / or the curb.

[0022] In the method, at least one of the length and the width of the transmission module may correspond to at least one of the length and the width of the paving stone.

[0023] In the method, the paving stone and the transmission module may be installed on a bed of sand, preferably compacted sand.

[0024] In the method, the lower surface of the paving stone, i.e., the underside, may be in the same plane as the lower surface of the transmission module.

[0025] The cable channel may be spaced apart from both the upper surface and the lower surface of the transmission module.

[0026] Each transmission module may include at least a pair of opposing sidewalls that are parallel and of equal length, and the cable channel may be arranged laterally spaced apart from the lateral center of each sidewall.

[0027] The lateral spacing may correspond to about 1 / 5 to 1 / 3 of the length of each opposing edge.

[0028] One or more of the sidewalls may have an engaging portion such as a groove or a through hole that enables mutual connection with the sidewalls of an immediately adjacent transmission module.

[0029] The transmission module may be hollow.

[0030] The paving stone may be formed of natural stone, cement, or a composite thereof.

[0031] Therefore, the paving stones may be formed of granite, marble, limestone, or the like. Alternatively, the paving stones may be formed of concrete or terrazzo.

[0032] The transmission module may be formed of a metallic material such as iron, steel, or aluminum.

[0033] The plurality of transmission modules may be installed in a row.

[0034] Alternatively or complementarily, the plurality of transmission modules may be installed in alignment, particularly in a straight line from the facade to the socket.

[0035] Alternatively, the plurality of transmission modules may be installed along a first direction, and immediately adjacent transmission modules may be offset from each other in a second direction perpendicular to the first direction.

[0036] According to a second aspect, a method of installing a socket for charging an electric vehicle on a curbstone is provided, the curbstone being spaced from a residential facade by a sidewalk. The method includes providing a power source at a first location along the curbstone, providing a socket at a second location along the curbstone, disposing at least two curbstone modules outside the lateral side of an existing curbstone block so as to extend between the first location and the second location, and installing a second power cable extending from the first location to the second location and disposed within a cable channel provided in the at least two curbstone modules.

The lower portion has at least one lateral opening sized and adapted to receive a power cable.

[0039] The opening is necessary for the supply of power for charging an electric vehicle and may be of sufficient size to easily pass a cable that can be installed within a protective sleeve. Thus, the opening should have a minimum dimension of at least 2 cm, preferably 3 cm, and in particular may extend vertically from the bottom of the lower part to the lower edge of the upper part.

[0040] The lower part in particular has at least two openings formed in opposite side walls, and the openings are aligned along a direction parallel to the side wall extending between the opposite side walls.

[0047] The anti-slip pattern may be formed as a relief pattern and / or an inverse relief pattern.

[0048] The transmission module may have a total thickness equal to the standard thickness of a paving stone of concrete or natural stone when the upper part is connected to the lower part.

[0049] Examples of standard thicknesses may be about 2 3 / 8 inches, about 3 1 / 8 inches, or 1 1 / 4 inches, expressed in US customary units. In metric units, the standard thickness may be about 3 cm, about 4 cm, about 5 cm, about 6 cm, about 7 cm, or about 8 cm.

[0050] The transmission module may be rectangular and have a maximum length equal to the standard length of concrete or natural stone paving stones.

[0053] The width of the transmission module may be about 1 / 2 of the maximum length, about 1 / 3 of the maximum length, or about 1 / 4 of the maximum length.

[0054] The transmission module may be rectangular. The size of the rectangular module may be about 35×17.5 cm, about 40×20 cm, about 50×25 cm, or about 60×30 cm.

[0055] In the transmission module, one of the side walls may extend to the end of the first edge of the bottom related to that side wall, and the other side wall may be related to the second edge of the bottom perpendicular to the first edge and may be spaced apart from the one side wall, so that the side walls do not intersect at the corners of the bottom. The non - intersection of the side walls at the corners of the bottom facilitates the production of the lower part.

[0056] According to a fourth aspect, there is provided a power supply device including an outlet for charging an electric vehicle, a power source, the plurality of transmission modules disposed on the same plane as the outer surface covering the area, and a cable disposed in a cable channel provided in the transmission module and extending from the power source to the outlet.

DETAILED DESCRIPTION OF THE INVENTION

[0072] Figure 1A shows a schematic view of a charging pole 1 installed on a curb 2 separating a sidewalk 4 from road areas 61, 62. The sidewalk 4 separates the building facade 5 from the curb 2. The road areas 61, 62 may include a plurality of parking spaces 61 and one or more traffic lanes 62.

[0073] The concept of the present invention aims to supply power to a charging pole 1 suitably arranged for charging an automobile parked in a parking space 61.

[0074] Referring to FIG. 1B, the curb 2 is formed from a plurality of curb blocks 21 that are arranged along the curb and typically separate the sidewalk 4, which is at a higher level than the road areas 61, 62, from the road areas 61, 62. Such curb blocks 21 are generally made of concrete, ceramic, clay, or natural stone, particularly granite or other stones with a similarly high hardness.

[0075] The sidewalk 4 has an outer surface formed by a plurality of paving stones 41 made of concrete, ceramic, clay, or natural stone. In the illustrated example, the paving stones 41 are installed in a staggered pattern, with the paving stones 41 aligned in a first direction D1 from the building facade towards the curb 2 and offset in a second direction D2 that is perpendicular to the first direction D1.

[0076] It is understood that the transmission module 42 described herein may be installed in various patterns, including a simple straight pattern, a herringbone pattern, a diamond pattern, etc., in addition to the offset pattern shown in the drawings.

[0077] The first and second directions D1, D2 are in the ground direction, i.e., the direction along the surface on which the paving stones are installed. Ideally, this direction is horizontal.

[0078] Therefore, the power supply 3, shown as an electrical cabinet arranged on the building facade 5 herein, is spaced from the curb 2 by the sidewalk 4.

[0079] FIGS. 1B and 2 show a flexible module-based concept for transmitting power from the power supply 3 arranged on the building facade 5 to the charging poles 1 of the curb and further charging poles 1.

[0080] FIG. 1B shows transmission modules 42a-42g that extend within each of the transmission modules 42a-42g and have cable channels parallel to the upper surfaces of the respective transmission modules 42a-42g. In particular, the cable channels may be vertically spaced from both the upward-facing and downward-facing surfaces of the transmission module when the transmission module is horizontally disposed. The transmission modules 42a-42g may have the same outer shape (thickness, length, width) as the paving stones 41, whereby the existing paving stones 41 can be removed and replaced by one or more of the transmission modules 42a-42g, and cables may be installed within the cable channels. Thus, by installing the transmission modules 42a-42g between the power supply 3 and the charging poles 1, a power supply for the charging poles 1 can be provided without the need for excavation.

[0081] At the curb 2, the base module 10 may be disposed. The base module 10 encloses a cable channel that is connected to the cable channels provided by the transmission modules 42a-42g. The base module 10 forms a base to which the outlet 12 is attached. The outlet may be attached to a pole 11 or the like that positions the outlet at a desired height level.

[0082] Also, FIG. 1B shows a pair of curb modules 22a, 22b that are installed laterally outside the existing curb 2, such as outside the pair of curb modules 22a, 22b, and enclose cable channels that enable cables to be installed along the curb 2, whereby a single one of the transmission modules of FIG. 1B can be used to supply power to a plurality of charging poles 1 that are spaced apart along the curb 2.

[0083] The curb modules 22a, 22b may be fixed in place by an adhesive, glue, cement, and / or mechanical fasteners.

[0084] FIG. 1C schematically shows another installation example, in which a single power supply 3 of the building facade 5 may be used to supply power to a plurality of outlets 1 that are spaced apart from each other along the curb 2.

[0085] In particular, the first row of the transmission modules 42 may be arranged aligned along a first direction D1, and the first direction D1 may extend in a straight line from the facade 5 to the socket 1 at a right angle to the facade 5, although this is not necessary.

[0086] The second row of the transmission modules 42 extends along a second direction D2, and the second direction D2 is parallel to the curb 2 and / or perpendicular to the row of the transmission modules 42 extending from the facade 5 to the first socket 1. In this second row, adjacent transmission modules may be offset from each other in a first direction D1 perpendicular to the second direction D2.

[0087] As referred to herein as a "half joint", i.e., the paving stones are offset by approximately half of their width, but depending on the installation pattern of the paving stones 41, adjacent transmission modules 42 may be offset by approximately 1 / 4 to 1 / 2 of their width.

[0088] By providing an opening for the cable offset from the center of the side wall of the cable module, it is possible to provide a straight or at least substantially straight cable channel even when the transmission modules 42 are offset laterally from each other.

[0089] FIG. 1D shows a schematic plan side view of the lower part 425 of the transmission module. In FIG. 1D, a vertical direction V and horizontal directions D1, D2 are shown.

[0090] The side wall 4252 of the transmission module has a lateral center C, and the opening 4258 is offset therefrom.

[0091] In the side wall 4252 shown in FIG. 1D, the side wall 4252 extends from one end of its associated edge past the lateral center C. Next, the opening 4258 extends from the other end of the associated edge to approximately the lateral center. In particular, the opening may extend beyond approximately 25% to 45% of the length of the associated edge.

[0092] Referring to FIG. 2, a transmission module 42 is illustrated that extends from one side surface to the opposite side surface and includes three cable channels 421 parallel to the module wear surface 422 of the transmission module 42.

[0093] The transmission module 42 is formed as a rectangular block having four side walls, an upward module wear surface 422, and a downward module wear surface 422 opposite to the module wear surface 422. The module wear surface 422 typically forms the surface that is exposed when the transmission module 42 is installed. Thus, in a horizontal installation area, the module wear surface 422 is arranged horizontally and each side wall is arranged vertically.

[0094] The curb module 22 is typically formed to include an upper surface 222, a front surface 223, and a cable channel 221 extending in a direction parallel to both the upper surface 222 and the front surface 223.

[0095] It is understood that the upper surface 222 and / or the front surface 223 may be inclined with respect to the horizontal plane or the vertical plane when the curb module is arranged on a horizontal surface.

[0096] The curb module 22 may be formed with a back surface opposite to the front surface 223 that is formed and adapted to correspond to and / or receive the shape of the existing curb block 21.

[0097] Preferably, the transmission modules 42, 42a - 42g, and / or the curb modules 22, 22a, 22b may be formed of concrete, rubber, cast iron, or other suitable materials.

[0098] The base module 10 may be formed with at least one or more openings 102, 104 provided in the upper part 106 of the base module 10. Such openings provide access to the internal space of the base module 10 and / or the attachment of the pole 11 or the pole adapter 103. A cover lid 105 may be provided to cover the openings not used for attaching the pole 11.

[0099] Also, the base module 10 may include at least one cable channel 101.

[0100] Such a cable channel 101 is provided to connect to one or more cable channels 421 provided by the transmission module 42 that enable power supply via the transmission modules 42, 42a - 42g.

[0101] Also, the cable channel is provided to connect to one or more cable channels 221 provided in the curb module 22 that enable power supply from the curb modules 22, 22a, 22b to other base modules 10 via other base modules 10 and / or from other base modules 10 to the curb modules 22, 22a, 22b.

[0102] Therefore, an electrical box or junction may be provided in the base module 10 to provide a desired connection from the power source to the outlet 12 and / or to the power source via the curb modules 22, 22a, 22b.

[0103] The base module 10 may preferably be formed of concrete or cast iron.

[0104] The transmission module and the base module may be installed in the same way as a normal paved road surface such as a floor of sand that may be particularly compressed. However, installation with concrete or other fixing materials is not excluded.

[0105] FIG. 3 shows a schematic view of an embodiment of a transmission module 42 that may be formed of a metallic material such as iron, steel, or aluminum.

[0106] The transmission module 42 shown in FIG. 3 includes a lower part 425 and an upper part 426.

[0107] The lower part 425 includes a bottom 4251 that may be substantially planar and rectangular, particularly square, and four side walls 4252, 4253, 4254, 4255 that extend substantially perpendicularly from each edge of the bottom 4251, respectively.

[0108] One or more of the side walls 4252, 4253, 4254, 4255 may typically include a fixing device 4256 at a distal portion of the side walls 4252, 4253, 4254, 4255. The fixing device 4256 may include one or more screw grooves or screw holes.

[0109] Each of the side walls 4252, 4253, 4254, 4255 may extend along all or part of each edge of the bottom 4251. In the illustrated example, the first side wall 4252 and the second side wall 4254 are disposed opposite each other and extend along a length that is slightly shorter than half the length of each edge. The first and second side walls 4252, 4254 may extend from each corner just past the lateral center C of the associated edge, thereby providing an opening for the remaining portion of each edge. The first and second side walls 4252, 4254 may extend from the corners of the same edge and may be aligned such that their openings 4258 are aligned.

[0110] Another pair of oppositely disposed side walls 4253, 4255 are formed by a third side wall 4253 that extends beyond approximately half of the associated edge and a fourth side wall 4255 that extends along the entire associated edge.

[0111] The third side wall 4253 may be disposed centered about the center C of the associated edge such that openings 4258 are provided on both lateral sides of the third side wall 4253.

[0112] One or more of the side walls 4252, 4253, 4254, 4255 may be provided at each distal portion with a flange 4259. Such a flange 4259 may provide mounting means for the upper part 426. As a non-limiting example, a fixture 4256 may be provided on the flange 4259. The flange 4259 may extend along the entire length of the side walls 4252, 4253, 4254, 4255, but is not limited thereto. The flange 429 may be provided as a portion extending substantially parallel to the bottom 4251, but is not limited thereto. The upper part 426 may be formed as a substantially planar portion having a size and shape corresponding to the bottom 4251 of the lower part 425, and optionally, one or more fixtures 4261 may be provided at positions corresponding to the fixing devices 4256 of the lower part 425.

[0113] The upper part 426 may have a step 4262 (see FIGS. 4 and 5) or chamfers at one or more of its edges to facilitate fitting and sealing to the lower part 425.

[0114] The wear surface of the upper part 426 may be provided with relief and / or reverse relief patterns to provide anti-slip properties and / or provide information.

[0115] Referring to FIG. 4, an alternative design of the transmission module 42 is shown, where the fixing device 4256 on the lower part 425 is provided as a protrusion extending upward from the bottom 4251 at the center of the bottom. The fixing device 4256 may be provided with a threaded hole. The protrusion may have a height such that when the upper part 426 is mounted on the lower part 425, the upper part 426 is sufficiently supported by the protrusion.

[0116] The lower part 425 shown in FIG. 4 generally has side walls 4252, 4253, 4254, 4255 and an opening 4258 of the same configuration, but does not have a flange 4259.

[0117] It is understood that the transmission module 42 may have a lower part 425 with both the flange 4259 of its side wall and the central protrusion shown in FIG. 4, and the fixing device 4256 may be provided on the flange shown in FIG. 3 and / or the central protrusion shown in FIG. 4.

[0118] The upper part 426 may be provided with a corresponding fixing device 4261 which may be provided as a through hole machined with a dish hole on the wearing surface.

[0119] Here, the illustrated upper part 426 further includes a stepped portion 4262, which is particularly useful in embodiments without the flange 4259 and is also useful in combination with the flange 4259.

[0120] Referring to FIG. 5, a lower part 425 having side walls 4252, 4253, 4254, 4255 is shown, and a pair of opposing side walls 4252, 4254 are separated by an opening 4258 extending over the entire height of the side walls.

[0121] In the example shown in FIG. 5, the openings 4258 are arranged offset laterally from the center C of the side walls on opposite sides of each other.

[0122] Furthermore, in the lower part 425 shown in FIG. 5, the opposing side walls 4252, 4254 having the openings 4258 also include engaging portions 4257, which may be in the form of grooves, hooks, or through holes (not shown), and may be used to interconnect a pair of juxtaposed lower parts 425, for example, to form the lower part of the base module 10.

[0123] The second pair of opposing side walls 4253, 4255 may extend over the entire associated edge so that no opening is formed in the side walls.

[0124] The lower part 425 shown in FIG. 5 may be formed with the flange shown in FIG. 3 and / or the central protrusion shown in FIG. 4.

[0125] The lower part shown in FIG. 5 may be used with the same upper part 426 as shown in FIG. 4 or as part of the composite base module 10.

[0126] FIG. 6 shows an alternative lower part 425 having only a pair of opposing side walls 4252, 4254 that may be designed according to the corresponding side walls of FIG. 5, with the other two opposing edges being open and without side walls.

[0127] The lower part 425 shown in FIG. 6 may be formed together with the flange shown in FIG. 3 and / or the central protrusion shown in FIG. 4. The lower part shown in FIG. 6 may be used together with the same upper part 426 as shown in FIG. 4 or as part of the composite base module 10.

[0128] FIG. 7 shows yet another alternative lower part 425 corresponding to that disclosed with reference to FIGS. 5 and 6, comprising a first pair of opposing side walls 4252, 4254 having offset openings 4258. Also, these opposing side walls 4252, 5254 have engagement portions 4257 for connecting to an adjacent lower part. A second pair of opposing side walls 4253, 4255 are completely open but have short wall portions 4253, 4255 at the corners of the lower part 425, and these wall portions have engagement portions 4257, such as those described with reference to FIG. 5.

[0129] Referring to FIG. 8, in any one of the transmission modules 42, any one of the side walls may be provided with one or more engagement portions 4257 as shown in FIG. 5 so as to be interconnected with an adjacent transmission module 42, for example by using fixtures such as nuts and bolts.

[0130] As shown in FIGS. 8 and 5, the engagement portion 4257 may be provided as a through-hole extending through the associated side walls 4252, 5254.

[0131] In FIG. 8, a flexible fixture in the form of a bolt 431 having springs 432, spring washers, etc. that are compressed between the wall 4252 and one of the bolt head and nut is shown to allow for some displacement and / or movement.

[0132] When the transmission module 42 is assembled, i.e., when the upper part 426 is fixed to the lower part 425, the overall thickness of the transmission module may correspond to the standard thickness of the paving stones.

[0133] The transmission module 42 shown in FIGS. 3 to 7 may be formed by metal casting. Alternatively, the transmission module may be formed by cutting and bending a metal sheet. Such a metal sheet may have a wall thickness of about 5 to 15 mm, preferably 7 to 10 mm.

[0134] FIG. 9 shows a base upper part 106 that may be used to form the base 10.

[0135] Two or more, here four, lower parts 425 may be interconnected by fixtures, for example as shown in FIG. 8.

[0136] The base upper part 106 has a shape and size corresponding to the associated lower part 425, whereby the base upper part 106 functions as the upper part of two or more interconnected lower parts.

[0137] For example, the base upper part 106 may have a first part 1061 corresponding to the first lower part 425 of the type shown in FIG. 7, a second part 1062 corresponding to the second lower part 425 of the type shown in FIG. 7 and rotated 180 degrees in the horizontal plane so that the third side wall 4254 is attached to the third side wall 4254 of the first lower part, a third part 1063 corresponding to the third lower part of the type shown in FIG. 7 and the first side wall 4252 is attached to the first side wall 4252 of the second lower part 425, and a fourth part corresponding to the lower part of the type shown in FIG. 7 and the second side wall 4253 is attached to the second side wall 4253 of the second lower part.

[0138] The version of the base upper part 106 shown in FIG. 9 is adapted to the lower part provided with the fixture corresponding particularly to FIG. 3.

[0139] The version of the base upper part 106 shown in FIG. 10 is adapted to the lower part provided with the fixture corresponding to FIGS. 4 to 7.

[0140] The upper part 106 of the base may have one or more openings 102, 104 that provide an interface for a pole or pole adapter or the like, or for a cover lid.

[0141] Figure 11 shows an alternative design for the transmission module and the base module.

[0142] According to this design, the transmission module 42 is formed with an extended shape having a length corresponding to two or more paving stones. For example, the length may be about 0.5 to 3 m, preferably 1 to 2 m. Such a length corresponds to the length and / or width of two or more paving stones.

[0143] Alternatively or additionally, the transmission module 42 may have a width corresponding to the width and / or length of one paving stone.

[0144] The transmission module 42 has a thickness corresponding to the thickness of the paving stone, but there is a tolerance. This tolerance may be less than 5%, preferably less than 1%.

[0145] Also, according to an alternative design, two or more transmission modules 42 may be joined together along their short sides to form a longer cable channel.

[0146] Also, Figure 13 shows the base module 10 formed by the lower part 425 and the upper part 426 of one base module.

[0147] The transmission module 42 and the base module 10 shown in Figure 11 may be manufactured in the same manner as the transmission modules shown in Figures 3 to 7, such as by casting or bending a metal sheet.

[0148] Figure 12 shows an exploded view of the transmission module and the base module of Figure 11, that is, a view with the upper part 426, 106 removed.

[0149] As can be seen, the lower part 425 of the transmission module may have a longitudinal inner wall that may extend along the longitudinal direction of the lower part 425 of the transmission module, whereby the channel is divided into two or more parts.

[0150] The longitudinal inner wall may additionally support the upper part 426.

[0151] The short side wall may have an opening for receiving one or more cables.

[0152] Furthermore, the short side wall may have a connecting device formed as described above.

[0153] Similarly, the lower part 107 of the base module may be divided into two or more sub-spaces by an inner wall.

[0154] The lower part 107 of the base module may have an opening for receiving one or more cables on one or more side walls.

[0155] Similar to the lower part of the transmission module, the lower part 107 of the base module may have a connecting device on one or more side walls.

[0156] In the illustrated example, the upper part 106 of the base module has a horizontal range corresponding to the lower part 107 of the base module.

[0157] Figure 13 shows the installation of the transmission module and the base module of Figures 11 and 12.

[0158] As can be seen from Figure 13, the 42 of a single transmission module extends from the building facade 5 to the curb 2, but this transmission module 42 may be formed by two or more interconnected transmission modules 42.

[0159] Also, as can be seen from Figure 13, there is a first base module 10 vertically installed from the power supply 3 of the building facade 5 on the curb 2.

[0160] To provide a cable channel to the second base module 10, an additional transmission module 42 extends along the curb 2.

[0161] Each base module supports one or more outlets.

[0162] Additional transmission modules and additional base modules may be provided along the curb 2.

[0163] Accordingly, the first connection from the power source 3 to the first base module 10 is provided via one or more transmission modules 42 that extend from the building facade 5 to the curb 2.

[0164] The second connection from the power source 3 or the first base module 10 to the second base module 10 is provided via one or more transmission modules 42 that extend along the curb 2.

[0165] The curb block 21 may be provided laterally outside of the transmission module 42 that extends along the curb 2.

[0166] FIG. 14 shows the installation of an alternative curb module.

[0167] This installation includes one or more transmission modules 42 formed according to any of the above alternatives.

[0168] Similarly, the base module 10 has one or more openings on its side for interconnecting with other base modules or with the transmission module 42. Also, this base module may be formed according to any of the above-disclosed alternatives.

[0169] The base module 10 may have one or more openings 101 in the sidewall facing laterally away from the curb for interconnecting with a curb module channel 221 formed in one or more curb modules 22.

[0170] Thus, instead of installing the cable in a channel formed in the surface of the paving stones along the curb 2, the cable may be installed in a channel extending within one or more curb modules 22.

[0171] The system shown in FIG. 14 further includes a curb end module 23 that may include a channel (not shown). The curb end module 23 has a tapered cross-section when viewed in plan from above.

[0172] The above concepts are illustrated with reference to a cable channel provided within a transmission module disposed in the same plane as an outer surface layer formed of paving stones, but it is understood that the transmission modules and installation methods described herein are also applicable in areas having an in-situ formed outer surface such as concrete, asphalt, terrazzo, etc.

[0173] In such cases, it is necessary to cut the outer surface area with a saw or milling to provide a groove having a width in which the transmission module 42 can be installed. Since the in-situ formed outer surface has various thicknesses, being too thin or too thick, it is desirable to apply a sublayer which may be sand, gravel, pebbles, or crushed stone so that the groove has a depth corresponding to the thickness of the transmission module.

[0174] Furthermore, it is desirable to fill all gaps between the transmission module and the surrounding outer surface. Such filling may be done by applying sand, concrete, bitumen, or other suitable types of sealing materials suitable for sealing the road surface.

[0175] Referring to FIG. 15, another method of forming the base module 10 is shown, where the first and second lower portions 245a, 425b formed as shown in FIG. 7 are connected by openings.

[0176] As shown in FIG. 6, the third and fourth lower parts 425c, 425d formed as such are connected to the first and second lower parts 425a, 425b on the side wall side, and the openings of the third and fourth lower parts 425c, 425d are aligned with the opening of the first lower part 425a.

[0177] The lower parts 425a, 425b, 425c, 425d may be interconnected by the connecting device shown with reference to FIG. 8.

[0178] Similar to that shown in FIGS. 9 and 10, an integrated upper part (not shown) may be arranged to cover the entire lower parts 425a, 425b, 425c, 425d.

[0179] Alternatively, an upper part covering the first and second lower parts 425a, 425b may be provided, and a normal upper part may be provided for the third and fourth lower parts 425c, 425d.

[0180] Referring to FIG. 16, another version of the lower part 425 is shown, and each side wall 4252, 4253, 4254, 5355 has two openings 4258 offset laterally from the lateral center C of each side wall.

[0181] Furthermore, in FIG. 16, each side wall 4252, 4253, 4254, 5355 includes a pair of corners extending from the ends of each edge, whereby an engaging part 425 and a central part that is spaced laterally from the corners by the opening 4258 and houses at least one engaging part 4257 are accommodated.

[0182] In the embodiment shown, the corners of the side walls may each extend along about 10 - 15% of the length of the edge.

[0183] The openings 4258 may each extend along about 20 - 25% of the length of the edge.

[0184] The central part may extend along 25 - 30% of the length of the edge.

[0185] The opening 4258 may extend across the entire height of the sidewall, but it is not necessary for it to do so.

[0186] The lower part 425 shown in FIG. 16 may be formed with a flange shown in FIG. 3 and / or a central protrusion shown in FIG. 4.

[0187] One or more metal sheet pieces (not shown) may be provided at the bottom of the base module and treated as additional weights to increase the weights of one or more transmission modules 42 and the base module 10.

[0188] Alternatively or additionally, the weight can be increased by filling the transmission module 42 or the base module 10 with sand or gravel.

[0189] For example, the central protrusion shown in FIG. 4 may be used additionally or exclusively as support for the upper central part such that when the upper part 426 receives a high load, deformation of the upper part 426 is reduced. Accordingly, the central protrusion may have a height corresponding to the height of the sidewall. Also, the central protrusion may not provide any fixing means at all.

[0190] FIG. 17 shows yet another version of the lower part 425 having a bottom 4251 and four sidewalls 4252, 4253, 4254, 4255.

[0191] The first and second opposing sidewalls 4252, 5254 extend along the entire length of each opposing edge except for the aligned openings 4258. The first and second sidewalls 4252, 4254 each have a first portion disposed at the end of the first edge and having a width sufficient to provide a space for the engagement portion 4257, and a second portion having a width slightly greater than half the length of the edge.

[0192] The third and fourth side walls 4253, 4255 extend along portions of each edge and are perpendicular to the first and second side walls 4252, 4254. The third and fourth side walls 4253, 4255 are spaced from the ends of the edge so as not to intersect the first and / or second side walls 4252, 4254.

[0193] At least one of the side walls 4252, 4253, 4254, 4255 may have a flange 4259, and the flange 4259 may have a fixing device 4256.

[0194] Alternatively, the lower part 425 shown in FIG. 17 may be designed to have no flange 4259 and instead have a protrusion disposed centrally that may accommodate a fixing device as shown, for example, in FIGS. 4, 5, 6, 7, 16.

[0195] FIG. 18 shows a schematic view of yet another version of the upper part 426 for a composite base module as shown, for example, in FIG. 15. The upper part 426 may be designed to cover four lower parts so as to generally have a cross shape. The upper part 426 may have at least one opening 102 or adapter for attaching the socket 12 or the socket pole 10, and one or more fixing devices 4261 for attaching the lower part 425 and / or the base part.

[0196] FIG. 19 shows a schematic view of yet another version of the upper part 426 for a composite base module. This upper part 426 may be formed as a rectangular part having one or more openings 102 or adapters for attaching the socket 12 or the socket pole 10, and one or more fixing devices 4261 for attaching the lower part 425 and / or the base part.

[0197] FIG. 20 shows a schematic view of a transmission module generally designed according to FIGS. 3 and 17, comprising side walls 4252, 5254 having inwardly curved flanges 4259 configured to accommodate the fixing device 4256.

[0198] FIG. 21 shows a schematic view of a transmission module generally designed according to FIGS. 4 to 7, 15 and 16, having side walls 4252, 4254 without flanges and instead having fixing devices 4261, 4256 arranged centrally.

[0199] FIG. 22 shows a schematic view of an alternative transmission module generally designed according to FIGS. 3 to 17, in which the flange 4259 is curved outwardly instead of inwardly as in FIG. 20.

[0200] For example, it is possible to combine a pair of opposing side walls designed according to FIG. 20 with another pair of opposing side walls designed according to FIG. 21 or FIG. 22. Optionally, the centrally arranged fixing device 4256 may be combined with a flange according to FIG. 20 or FIG. 22.

[0201] FIG. 23 shows a schematic perspective view of a connecting element 500 for mechanically connecting the lower parts 425 of a pair of adjacent transmission modules.

[0202] The connecting element 500 of FIG. 23 comprises element bodies 501, 502, 503 having a pair of opposing side surfaces, a first groove 504a formed in the first side surface, and a second groove 504b formed in the second side surface. The first and second grooves 504a, 504b each have a longitudinal direction parallel to each other.

[0203] The element body has a first direction D1 extending between the opposing side surfaces, a second direction D2 extending perpendicular to the longitudinal direction of the groove, and a third direction D parallel to the longitudinal direction of the groove.

[0204] The grooves 504a, 504b may be straight and may each have a longitudinal direction of the groove that may be parallel to the third direction D3, a depth direction of the groove that may be parallel to the first direction D1, and a width direction of the groove that may be parallel to the second direction D2.

[0205] The element body may comprise a first wall portion 501 extending along the first and second directions D1, D2, and the first wall portion 501 has a thickness direction extending along the third direction D3.

[0206] The element body may include a pair of second wall portions 502 extending along the second and third directions D2 and D3, and the pair of second wall portions 502 has a thickness direction extending along the first direction D1.

[0207] In the embodiment shown in FIG. 23, the element body may include a pair of third wall portions 503 extending along the first and second directions D1 and D2, and the pair of first wall portions 503 has a thickness direction extending along the third direction D3.

[0208] The first and third wall portions 501 and 503 may be parallel to each other. The second wall portion 502 may be perpendicular to the first and / or third wall portions 510 and 503.

[0209] The grooves 504a and 504b extend over the entire second wall portion 502, but this is not necessarily the case.

[0210] The element bodies 501, 502, and 503 may be cubic or rectangular parallelepiped. However, the corners may be somewhat rounded or chamfered.

[0211] FIGS. 24A to 24D show schematic views of a method of mechanically connecting the lower portions 425 of a pair of adjacent transmission modules. In FIGS. 24A to 24D, the joining plane is defined as a vertical plane parallel to the side wall 4253 to be connected.

[0212] Referring to FIGS. 24A through 24D, the connection element 500 is intended to be used to interconnect the side walls 2453 of adjacent transmission modules 42 when the transmission modules 42 are arranged on the same plane such that the lateral opening 4258 in the lower part 425 of the first transmission module forms a channel connecting the inside of the first transmission module 42 and the inside of the second transmission module, and the lateral opening 4258 in the lower part 425 of the first transmission module is aligned with the lateral opening 4258 in the lower part 425 of the second transmission module. As shown in FIG. 24A, the channel 450 is laterally restricted by the vertically extending wall edge portion 42531 of the side wall 4253. The wall edge portion 42531 is arranged on the horizontally opposite side of the channel 450 when the lower part 425 of the transmission module is arranged on a horizontal plane. Accordingly, a pair of aligned wall edge portions 42531 are provided on each lateral side of the channel 450, and each wall edge portion 42531 forms a part of one of the respective lower parts 425 of the transmission modules to be connected.

[0213] As shown in FIG. 24B, the connection element 500 is applied to the opening 4258 forming the channel 450 by each pair of aligned wall edge portions 42531 respectively received in one of the first and second grooves 504a, 504b, thereby preventing relative movement of the lower part 425 of the transmission module in directions perpendicular and horizontal to the joint surface.

[0214] Also, as shown in FIG. 24B, a first connection element 500 having a height in a third direction corresponding to approximately half of the height of the channel 450 is used.

[0215] As shown in FIG. 24C, a second connection element 500 may be the same as the first connection element 500, but this is not necessary.

[0216] As shown in FIG. 24C, the first connection element may be arranged such that the lower part of the opening is restricted by the first part 501 of the element body, and the second connection element may be arranged such that the upper part of the opening is restricted by the first part 501 of the element body.

[0217] In FIG. 24D, it shows how the upper part 426 fixes the connecting element 500 in its position and prevents the vertical relative movement with the lower part 425 of the transmission module by the method described above.

[0218] It is understood that the grooves 504a, 504b may be designed in various ways.

[0219] In some embodiments, particularly in embodiments where the connecting element 500 is effectively rigid, it is desirable to allow some play along at least one of the directions D1, D2, D3 to accommodate tolerances, minor misalignments of the lower part 425 of the transmission module, and / or movements expected in related types of installations. Such play may be captured by providing one or more elastic compounds or elastic elements to provide a seal and / or prevent the connecting element 500 from generating noise when moving relative to the lower part 425 of the transmission module, but this is not necessary.

[0220] Such elastic compounds or elastic elements may be applied in relation to the fabrication of the connecting element 500, or in relation to the installation or facilitation of the connecting element 500.

[0221] Therefore, the width of the groove may be at least twice the thickness of the side wall of the lower part 425 of the transmission module. Also, the width of the groove may be adapted to accommodate any space that may exist between the connected side walls. For example, the joint space may be filled with a joint material such as sand, grout, etc.

[0222] Alternatively, the grooves 504a, 504b may be provided as a pair of spaced sub-grooves adapted to engage each one of the edges 42351 of the adjacent side walls so that a predetermined joint interval between the lower parts 425 of the transmission module is maintained by the connecting element 500.

[0223] In addition, the connecting element 500 may provide protection to the cable drawn through the cable channel 450. Thus, the cable can be protected so as not to be rubbed or cut by the edge that limits the opening 4258.

[0224] FIG. 25 shows a schematic perspective view of an alternative design of the connecting element.

[0225] This alternative design of the connecting element 500 is different from that shown in FIG. 23 in that the second wall portion 502 extends longer in the third direction so that the connecting element 500 has a height corresponding to substantially the full height of the channel 450, whereby, as shown in FIG. 26 schematically showing a connecting element according to a first alternative design in a state of mechanically connecting a pair of adjacent transmission modules, only one connecting element 500 is required.

[0226] The connecting element 500 shown in FIGS. 23 to 26 may be created by casting / molding or by bending and cutting a sheet-like substrate. In the latter case, the first, second, and third wall portions 501, 502, 503 may have the same thickness.

[0227] The connecting element 500 may be formed from a metal, particularly a sheet-like metal and / or an essentially rigid material such as cast iron.

[0228] Alternatively, the connecting element 500 may be formed from an elastic material such as engineering plastic, thermoplastic elastomer, rubber, silicone, or the like.

[0229] The connecting element formed of a more rigid material may be provided with notches for allowing a certain amount of deformation without breaking.

[0230] It is also conceivable to provide a connecting element formed of two or more materials such as a rigid core (metal or plastic) with a more elastic portion or coating.

[0231] Figures 27A and 27B show schematic perspective views of a connecting element 500 according to second and third alternative designs, which may be suitable for manufacturing by casting and / or molding.

[0232] In particular, the first wall portion 501 of the element body may extend along the first and second directions D1, D2 and have a thickness direction extending along a third direction.

[0233] The second wall portion 502 may extend along the second and third directions D2, D3 and have a thickness direction extending along the first direction.

[0234] The thickness of the second wall portion 502 may be greater than the thickness of the first wall portion 501.

[0235] The grooves 504a, 504b are formed in the second wall portion, and the groove depth may be smaller than the thickness of the second wall portion 502.

[0236] Figure 27A shows a connecting element 500 having the same height and use as in Figure 23.

[0237] Figure 27B shows a connecting element 500 having the same height and use as in Figure 25.

[0238] Figure 28 schematically shows a connecting element according to a third alternative design in a state of mechanically connecting the lower parts 425 of a pair of adjacent transmission modules.

[0239] Figure 29 shows a schematic view of a transmission module in the form of a "half tile" including a lower part 425 and an upper part 426. Such a half tile has a first side having the same length as a standard tile such as 35 cm, and a second side perpendicular to the first side having a length of about 50% of the length of the first side.

[0240] FIG. 30 shows a schematic view of a spacer element 550 that may be used to provide a lateral spacer to adjacent transmission modules 42 and / or paving stones. According to the design, the spacer element 550 may be used as a blind element to close the opening 4258 in the sidewall when it is desirable to prevent or reduce the entry of water, joint filler, and / or debris, etc.

[0241] As shown in FIG. 30, the spacer element 550 may comprise an essentially planar spacer element body 551 having a first pair of opposing surfaces 5511 extending in the first and third directions D1, D3, a second pair of opposing surfaces 5512 extending in the first and second directions D1, D2, and a third pair of opposing surfaces 5513 extending in the second and third directions D2, D3.

[0242] The first side 5511 may form the main surface of the spacer element 550.

[0243] The second side 5512 may form the thickness of the spacer element 550.

[0244] The second pair of opposing surfaces 5513 have a first groove 554a formed in one of the opposing surfaces 5513 and a second groove 554b formed in the other of the opposing surfaces 5513. The first and second grooves 554a, 554b each have a longitudinal direction parallel to each other.

[0245] Thus, the spacer element body 551 has a first direction D1 extending between the opposing side surfaces, a second direction D2 extending perpendicular to the longitudinal direction of the grooves, and a third direction D3 extending parallel to the longitudinal direction of the grooves.
