DETAILED DESCRIPTION OF THE INVENTION

[0048] FIGS. 1 and 2 show a body through which a medium can flow 1 in the form of a pipe. The body through which a medium can flow 1 has an inner flow lumen 10, through which a medium such as fluid and/or gas can flow. The inner flow lumen 10 is surrounded by a supporting body 11 that provides mechanical support, wherein the supporting body 11 is designed here as a pipe. On the exterior 12 of the supporting body 11 is a device for absorbing nutrients and/or fluid as a layer 13 for medium storage. The medium here can be, for example, water. The device or layer 13 for absorbing nutrients and/or fluid is made out of at least one open-cell foamed plastic, that is, an open-cell foam material. A plant layer 2, which is grown or located on the exterior 14 of the body through which a medium can flow 1 and thus the device or layer 13, can attach and take hold particularly well on the device or layer 13 because of the open-cell plastic material.

[0049] The supporting body 11 can consist of a material that is permeable in particular to fluid in order to supply the device or layer 13 around it with fluid, in particular water. The supporting body 11 can also be designed such that it is impermeable to water, for example as a T-beam, an I-beam, or another type of supporting body. It can also serve for example as a closed pipe that is only for the supply and discharge of medium. Furthermore, it can also span only through a partial section of the device or layer 13 for absorbing nutrients and/or fluid in the form of a foam body. The latter can comprise at least one outer open-cell foam layer 130 for stapling plants into and at least one inner foam layer 131 for storing fluid, such as water, and nutrients (see FIGS. 1 and 2). The outer foam layer 130 can preferably be made of polypropylene (PP) or at least one bioplastic, such as polylactic acid (PLA). The inner foam layer 131 can be made for example out of polyurethane (PUR) or another foam material.

[0050] The plant layer 2 on the exterior 14 of the body through which a medium can flow 1 will be supplied with nutrients and/or fluid, thus in particular water or an aqueous solution, that for example can flow through the supporting body 11, via the device 13 or inner foam layer 131. The device 13 or inner foam layer 131 and the outer foam layer 130 can completely encircle the supporting body 11. It is likewise possible for the device 13 or the inner or outer foam layer 131 or 130, respectively, to surround the supporting body 11 only in part.

[0051] The body through which a medium can flow 1 serves as the support for the plant layer 2 and can be oriented vertically, horizontally, or at an angle. This is to be regarded in particular in FIG. 4 through 7a, which will be described in more detail below.

[0052] The body through which a medium can flow 1 can also be provided without the supporting body 11, in which case the device for absorbing nutrients and/or fluid 13 is designed to be self-supporting. In this case, it has sufficient mechanical stability, so that an additional supporting body 11 under this inside the body through which a medium can flow 1 is not required. As described above, this can also span only over a partial section of the body through which a medium can flow 1 for the supply and discharge of medium.

[0053] It is also possible to construct the body through which a medium can flow 1 in multiple layers, wherein different functional layers are arranged one on top of the next. For example, a layer that provides mechanical stability can be the innermost layer, which surrounds the flow lumen 10, as long as there is no supporting body 11, followed by a nutrient-storage layer, a fluid-storage layer, and a fluid-guiding layer. Other functional layers can also be provided. It is also possible to keep the inner flow lumen 10 open on one side as a cavity for fluid such as water to flow, such as in the embodiment shown in FIGS. 1 and 2. It is likewise possible to fill this with foam material and/or, for example, absorbent granules (see FIGS. 9a, 9b), through which the fluid and/or gas or general medium can flow.

[0054] The open-cell foamed plastic of the device 13 or the inner or outer foam layer 131 or 130, respectively, can contain a superabsorbent material to improve fluid retention. Because superabsorbent material is inherently intended for the retention of fluids and for the prevention of distribution, there is advantageously at least one device for enabling and/or improving distribution of the fluid retained in the superabsorbent material to the plants.

[0055] The open-cell foamed plastic, that is, the open-cell foam material, can be made based on, for example, polyamide (PA), polypropylene (PP), polyethylene (PE), polyurethane (PUR), or at least one thermoset or at least one bioplastic, such as polylactic acid (PLA). Other polymers that are open-cell in their foamed state can also be used here. The combination of several foam materials is possible, in particular when forming a multi-layer body through which a medium can flow 1. The individual layers or at least one of the layers can also be designed as a semipermeable layer, that is, only permeable in one direction, in particular to water. A barrier in the other direction is thus created, so that in particular the passage of water in only one direction is enabled. The direction of passage is advantageously in the direction of the plant layer 2 on the exterior 14 of the body through which a medium can flow 1 or the device 13 for absorbing nutrients and/or fluid. For example, such a semipermeable layer can be arranged as a filter layer between the inner flow lumen 10 and the device 13 for absorbing nutrients and/or fluid in the form of at least one foamed plastic.

[0056] The outer diameter D of the body through which a medium can flow 1 in the embodiment as a pipe, or with an internal supporting body 11 in the embodiment as a pipe, such as is shown in FIGS. 1 and 2, can be for example 2 cm to 20 cm. Other diameters are also possible, wherein the range of 2 cm to 20 cm is particularly advantageous with regard to water transport, weight, and plant growth.

[0057] Instead of the round shape of the body through which a medium can flow 1 designed as a pipe according to FIGS. 1 and 2, this or these can also be oval and/or polygonal and/or asymmetrical or irregular in profile. The body through which a medium can flow 1 can thus be adapted in form to the respective application. The body through which a medium can flow 1 can also have different cross-sections and also different dimensions along its length in sections.

[0058] A polygonal profile opens the possibility of using individual surfaces for different purposes, that is for example, two of the three sides of a triangle profile can be greened and one, or the third, side can have one or more solar cells to supply a photovoltaic system and thus provide electrical power to supply for example a pump device 32, as shown in FIG. 8, that serves to recycle the medium from an area of the ground to a body through which a medium can flow 1 or for the transfer of medium from a reservoir to a body through which a medium can flow 1 that is higher up.

[0059] On the open-cell surface of the at least one outer foam layer 130 or the device 13, the plants can take hold very well in forming the plant layer 2 and can be nourished this way. The plants of the plant layer 2 can thus be completely supplied with water and/or nutrients via the body through which a medium can flow 1, wherein either only water together with nutrients flows through the body through which a medium can flow 1, in particular its supporting body 11, to the plants of the plant layer 2 via the device 13 for absorbing nutrients on the exterior of the body through which a medium can flow 1, or if the supporting body 11 is omitted, through the individual layers of the body through which a medium can flow 1, which is multi-layered if applicable, still at least through its device 13 for absorbing nutrients and/or fluid, to the plants of the plant layer 2.

[0060] In particular when manufacturing a body through which a medium can flow 1 in the form of a pipe, this can be cut to individual pipe section lengths as needed. The individual pipe sections can then be connected to one another or to supply lines for delivering medium, such as water and nutrients, as is suitable for an individual case. Such a connection can be accomplished for example by plug connections. Accordingly, the pipe sections created by cutting to length can have suitable connecting or interface sections or line connectors at the end to add the individual pipe sections to a pipe system or to connect them to medium supply or discharge devices, such as for example a water intake point or a drain system.

[0061] Such a pipe section 15 is shown in FIG. 3. This has on its end 16 a section 17 that is funnel-shaped on the inside and a valve flap 18 as a valve device in the funnel-shaped section 17. This is thus located in the interior 19 of the pipe section 15 or its device for absorbing nutrients and/or fluid 13 such that the valve flap 18 in the supply closes via spring force to prevent the interior from drying out even with low water levels. It opens toward the inside of the inner flow lumen 10 to enable the inflow of medium, such as water, into the inner flow lumen 10 of the pipe section 15. After closing the valve flap 18, moisture, or water, can be retained inside the pipe section 15, or very generally, inside the body through which a medium can flow 1. Moisture retention of the pipe section 15 and thus maintenance of the water supply of the plant layer 2 on its exterior is thus possible. At the other end of the pipe section 15 or on further pipe sections 15 connected with this, there can likewise be for example a valve device, in particular a valve flap like valve flap 18, to prevent the discharge of water out of the inner flow lumen 10 of the pipe section 15 and thus to retain a sufficient volume of water in the pipe section(s) 15 so that the plant layer 2 on the exterior of the pipe section(s) 15 can be constantly supplied with water and nutrients. Instead of the valve flap 18, as examples, a recirculation system or the hydrostatics of the greenery system can be designed such that medium is retained inside the at least one pipe section 15.

[0062] In particular, there can also be a corresponding valve device in the area of a media line connected to the pipe section 15 leading into an area of the ground 61 in front of or under a building 6 to discharge the medium, such as water, that is discharged from the pipe section 15 there. Such a valve device 150 can for example be a funnel-shaped device or a diaphragm valve, which is implied in FIG. 3 at the end of the pipe section 15.

[0063] In FIG. 4, a greenery element 5 of a greenery system 3 is shown that is designed here as a shading system for shading a window 65 of a building 6. The greenery element 5 comprises here for example eight slats 4, which each have one body through which a medium can flow 1, to enable greening. The number of slats 4 can be selected according to the application. The slats serve to provide shade and are retained on their ends in two guide rails 40, 41 that are approximately parallel to one another. Connecting both guide rails 40, 41 to one another is a shade element 42 above the slats 4, which covers the adjusting devices etc. for operating and adjusting the slats 4. To connect the individual slats 4 with one another in terms of fluid, these can be connected via media lines, for example in the form of hoses 43, as shown in FIG. 5, in terms of fluid.

[0064] Instead of hoses, fluid connectors can also be used, such as copper pipe connectors or other types of connectors. The uppermost slat 4 can be supplied with fluid, in particular water, via a supply line 33 of a medium supply device 38, as shown in FIG. 8 as an example. The fluid or water flows into the first slat 4, through this, to the other end of the slat 4 via the hose 43, into the second slat 4 underneath, through this to the hose 43 and the other end of the second slat 4, through this into the third slat 4 underneath, through this to its opposite end, from this into another hose 43 located there, and out of this into a fourth slat 4 below the third slat 4. After flowing through this fourth slat 4 as well, the fluid such as water can discharge at the other end of this into a medium discharge device 39. The latter can comprise a media line, which for example opens into the ground 61 in front of the building 6, which is not shown, however, in FIG. 5. Instead of this series circuit, there can also be a parallel circuit of the slats 4 or a mixed series-and-parallel circuit. In FIG. 5, the four slats 4, shown as examples, are approximately horizontal and are arranged one on top of the next over an implied window 65 of the building 6 that is only implied. Instead of this, there can also be a different number or arrangement of slats 4.

[0065] Instead of the horizontal operating position arrangement of the bodies through which a medium can flow 1 in the slats 4 or the body through which a medium can flow 1 designed as slats 4, this can also have an approximately vertical orientation, such as the embodiment variant shown in FIG. 6, or be oriented at any angle to the vertical or horizontal. In FIG. 6 as well, the five bodies through which a medium can flow 1 in the form of slats 4, shown as examples, form a greenery element 5. The first slat 4 is connected to a rain gutter 60 of a building 6 in terms of fluid via a supply line 44, and the fifth and thus last slat 4 opens into a canal system in the ground 61 in front of the building 6 via a discharge line 45. The canal system is, however, not shown in FIG. 6. The slats 4 oriented vertically in this embodiment variant of the greenery element 5 of the greenery system 3 are also connected with one another in terms of fluid via connecting lines 46. Furthermore, the slats 4 are mechanically connected together to the greenery element 5. The five slats 4, shown as examples, connected together to the greenery element 5, including the bodies through which a medium can flow 1, thus form one unit that can be arranged and attached in front of or on a facade 62 of the building 6. The greenery element 5 can thus be installed such that it is fixed to the building 6 or its facade 62, and connected on one side to a rain gutter or another water collecting element 60, located in particular in the area of the roof 63 of the building 6, and it can be connected on the other side to the ground 61 or a canal system therein. These slats 4 can also be retained such that they are fixed or movable in the corresponding guide rails to be able to locate them, for example, in front of the window 65 of the building 6 so that the greenery element 5 is then part of a shading system for the window 65.

[0066] In FIGS. 7, 7a, a further embodiment of greenery elements 5 of the greenery system 3 is shown. Herein, there is a number of bodies through which a medium can flow 1 that are oriented approximately horizontally and parallel to one another on the wall elements 70 of a pavilion 7. Alternatively, the greenery elements 5, or at least one of these, can be designed to be self-supporting so that the wall elements 70 can be omitted and the greenery elements 5 themselves can form the wall elements.

[0067] The wall elements 70 of the pavilion 7 can be greened by the greenery elements 5 in that one plant layer 2 can in turn grow or be located on each of the bodies through which a medium can flow 1. With this embodiment variant of the greenery elements 5 as well, the bodies through which a medium can flow 1 are connected to one another in terms of fluid, wherein in particular the respective uppermost body through which a medium can flow 1 is or will be connected to a water collection element in the form of a rain gutter 71 via a supply line, which is not shown in FIGS. 7, 7a, whereas the lowest body through which a medium can flow 1 will be connected with an area of the ground 72 that the pavilion 7 is on in terms of fluid via a discharge line, which is likewise not shown, so that the uppermost body through which a medium can flow 1 can be fed with rainwater captured by a water collection element in the form of a rain gutter 71 via the supply line, the water being sent from the respective body through which a medium can flow 1 above to the one below it, via respective connecting lines between the individual bodies through which a medium can flow 1, until finally at the lowest body through which a medium can flow 1 after the flow-through of the rest of its medium, in particular water, is discharged out of this to the outside via the discharge line and into the ground 72, in particular to a collecting container located there, such as a cistern or a canal system.

[0068] Instead of a horizontal or vertical orientation of the bodies through which a medium can flow 1, or slats 4, which these have or form, a respective greenery element 5 can also have bodies through which a medium can flow 1 oriented in any direction, that is, in particular such that they are at an angle to the vertical whereby the retention time of the fluid, such as water, inside the body through which a medium can flow 1 can be set via the selection of the angle of the bodies through which a medium can flow 1. Hydrostatic effects can thus be used optimally.

[0069] As long as a recycling of medium, in particular water, from the ground back to the uppermost body through which a medium can flow 1 of the greenery element 5 of the greenery system 3, or a transfer from a water reservoir, such as a cistern or a canal system, to the uppermost body through which a medium can flow 1, should occur, this can occur for example via a pump device 32 of the medium supply device 38, as shown in FIG. 8. The greenery system comprises here four greenery elements 5, for example such as those shown in FIG. 4 through 7a, each of which can comprise a number of bodies through which a medium can flow 1. This will be supplied with medium or water from a water reservoir 31 via a supply line 30, transferred via the pump device 32. To filter solids out of the water, which will gather in the water reservoir 31, before the water reaches the pump device 32 and clogs or damages it, there is a filter element 34 in a supply line 33 between the water reservoir 31 and the pump device 32. To supply the pump device 32 with power, it very advantageously has a self-sufficient power supply from a power supply device 37, which can have for example a photovoltaic system with solar modules or even a micro wind system. Shown in FIG. 8, for example, are solar modules 35, which are connected to the pump device 32 via an electrical line 36. The greenery system 3 is thus self-sufficient, as the pump device 32 can be permanently supplied with power via the solar modules 35, so that water from the water reservoir 31 can be continuously supplied to the greenery elements 5 of the greenery system 3, which can comprise a number of bodies through which a medium can flow 1, via the supply lines 33, 30. In particular, this can also have a return line back to the water reservoir 31, which can be part of the medium discharge device 39. The water that was not absorbed by the plants of the plant layer 2 that surrounds the body through which a medium can flow 1 can be returned to the water reservoir 31 via the return line, or the medium discharge device 39, to make it available again for the water supply of the greenery elements 5 of the greenery system 3.

[0070] In FIGS. 9a and 9b is an alternative embodiment of the body through which a medium can flow 1, which can be used as vertical blinds. The body through which a medium can flow 1 is not greened all the way around in the variant shown in FIG. 9a an 9b; rather, its exterior has an unoccupied surface for provision of, for example, solar cells, at least one lighting device, or even an advertisement or similar. In this embodiment variant of the body through which a medium can flow 1, it is thus not required to have separate solar modules; rather, these can be arranged directly on the exterior of the body through which a medium can flow 1. For this purpose, the body through which a medium can flow 1 has on its exterior a cylindrical perforated sheet 8 as an outer skin surface of the body through which a medium can flow 1, a distance from which is the supporting body 11, here in the form of an inner pipe, and dividers 80 as spacers between the supporting body 11 formed as an inner pipe and the cylindrical perforated sheet 8. The device for absorbing nutrients and/or fluid 13, in particular in the form of a foam material, is in the space between the supporting body 11, the cylindrical perforated sheet 8, and two dividers 80, which delimit a ring segment or segment 84. The plant layer 2 is grown on the exterior of the device for absorbing nutrients and/or fluid 13 as greening. In this section or segment 84 of the body through which a medium can flow 1, there can be through holes or openings for supplying the plant layer 2 with medium, such as water, in the supporting body 11 formed as an inner pipe. These through holes 110 are only implied in FIG. 9b. Medium, in particular water, can flow through the inner pipe, or the supporting body 11, and/or at least one pipe inserted there. Accordingly, the inner flow lumen 10 of the supporting body 11 formed as an inner pipe can be open. Furthermore, it is possible to fill this with for example absorbent granules so that the medium will be absorbed into this or can flow into this, and will accordingly be available for supplying the plant layer 2 of the exterior 81 of the cylindrical perforated sheet 8.

[0071] The segments 82, 83 of the bodies through which a medium can flow 1 that are not greened in FIGS. 9a and 9b, that is, do not contain the plant layer 2, can for example be used for arranging LEDs or solar cells, wherein these are arranged on the cylindrical perforated sheet 8 and can be attached there. This exterior 81 of the perforated sheet 8 is also available for additional planting, for example with different plants based on the season. Accordingly, for example, a segment 83 of the body through which a medium can flow 1 that is between two respective dividers 80 can be used for planting summer plants, and another segment 84 for planting winter plants. These segments can each have a device 13, in particular foam material. The exterior 81 of the cylindrical perforated sheet 8 of the body through which a medium can flow 1 can also be used as an advertising surface, for example in the area of segment 82 and/or 83, via a corresponding print or corresponding advertising medium.

[0072] There can be a cover plate 163 at the top or first end 160 and/or the bottom or second end 161 of the body through which a medium can flow 1 in FIG. 9a. As can be inferred from FIG. 10, there can also be a drive device 164 on the top or first end 160 of the body through which a medium can flow 1. This is a gear as an example in the example embodiment shown in FIG. 10, wherein there can also be another type of drive device here. Rotation of the body through which a medium can flow 1, in particular that that is oriented vertically (in the form of vertical blinds), is possible via the drive device, which can for example be driven via an electric drive. Different sides or sections of the exterior of the body through which a medium can flow 1 can thereby be oriented differently based on the time of year or even the time of day, toward a building or a facade or a wall element, etc., or toward sunlight. A specific side or a specific circumferential section can thus be visible from the outside on demand at different times throughout the day, while the other circumferential section of the body through which a medium can flow 1 is oriented, for example, toward the facade of a building, a wall element, etc. To enable smooth rotation of the body through which a medium can flow 1, this has at its top or first end 160 a quick-connect device 165, via which a connection of the supporting body 11 formed as an inner pipe to a distribution pipe 166 is possible. The quick-connect device 165 can be designed as a one-click-style mechanism, and it enables in particular a quick replacement of the body through which a medium can flow 1, and thus individual slats 4 of a greenery element 5 or the greenery system 3 in the event of service or repair work. The quick-connect device 165 can easily be accessed and operated in particular from the accessible side, such as a front side, of a corresponding greenery element 5, without removing other components from this. Additionally, disassembly of the entire greenery system 3 upon failure is not required and entails only removal of individual slats 4. A spring-loaded pressure plate, for example, can also be provided as a possible embodiment of the quick-connect device 165, the plate being designed such that it can be plugged into a receptacle in the distribution pipe 166. Other embodiment variants of the quick-connect device 165 are also possible.

[0073] Within the supporting body 11 formed as an inner pipe, there can also be at least one riser pipe, which serves to drain medium in the event of complete saturation of the absorbent granules that fill the inner pipe.

[0074] In addition to the embodiment variants of bodies through which a medium can flow and a greenery system with at least one greenery element with at least one such body through which a medium can flow that are described above and shown in the figures, numerous other embodiments can be designed, in particular any combinations of the aforementioned characteristics of these, wherein each of the bodies through which a medium can flow is either self-supporting or comprises at least one supporting body that provides mechanical stability and at least one device for absorbing nutrients and/or fluid, wherein a plant layer can be supported, grown, or located on the exterior of the body through which a medium can flow. The greenery system comprises at least one greenery element with at least one such body through which a medium can flow and at least one medium supply device for the supply of medium to the at least one body through which a medium can flow and at least one medium discharge device for directing medium out of the at least one greenery element, in particular into the ground.
