Description

[0001] Plastic multi-purpose system for irrigation and / or

[0002] Drainage and its use

[0003] Description

[0004] The present invention relates to a plastic grid multi-purpose module and a plastic multi-purpose system for irrigation and / or drainage and its use.

[0005] background

[0006] State-of-the-art plastic grid components are known, which can be used as a flat composite for ground stabilization, as a foothold for animals, or even on roofs for green roofs. Such plastic grid components often prove disadvantageous in practice, as plant growth in the open spaces of the plastic grid multi-purpose module is virtually impossible, particularly during hot, dry periods. The goal of holistic greening for visual enhancement and the creation of additional habitats for insects and soil organisms is missed.

[0007] Task

[0008] It is therefore the object of the present invention to provide a plastic multi-purpose system for irrigation and / or drainage which can be used in a multi-functional way. It is also the object of the present invention to provide a plastic multi-purpose system for irrigation and / or drainage which can be used permanently even when subjected to heavy traffic. It is also the object of the present invention to provide a plastic multi-purpose system for irrigation and / or drainage which can be produced cost-effectively. It is also the object of the present invention to enable reliable and permanent water control for roofs and floors so that the soil fauna is strengthened and new habitats for insects are created.

[0009] Solution

[0010] The problem is solved by the technical features specified in claim 1.

[0011] The core idea of ​​the present invention is to design a plastic grid multi-purpose module with a surrounding outer frame which spans an interior region, wherein the outer frame is stabilized by longitudinal struts and transverse struts extending in the interior region, so that a grid structure is formed. In addition, some of the longitudinal struts and / or transverse struts are at least partially non-linear. Furthermore, the outer frame has at least one passage opening. Furthermore, at least one of the longitudinal struts and / or at least one of the transverse struts has at least one further passage opening, wherein the at least one passage opening of the outer frame is aligned with the at least one passage opening of the longitudinal strut or the transverse strut.

[0012] The advantage of the invention described here lies in the fact that its special geometric design allows for the provision of a highly stable multi-purpose plastic grid module. Several of these multi-purpose plastic grid modules can be coupled together to form a flat composite on and / or in a wide variety of substrates.

[0013] This is advantageous because it makes it possible for the first time to arrange at least one supply line without crushing beneath the plastic mesh multi-purpose module, advantageously beneath several interconnected plastic mesh multi-purpose modules. For particularly simple installation, the at least two passage openings are aligned with one another.

[0014] The grid geometry is regular. It features different types of subunits. These are formed by struts, preferably longitudinal struts and transverse struts. Furthermore, the special geometric shape of the plastic grid multi-purpose module has proven advantageous, as it compensates for thermal expansion of the material on hot days.

[0015] Advantageous further training can be found in the subclaims.

[0016] In a further advantageous embodiment, at least three differently designed sub-units form the plastic grid multi-purpose module. A first type of sub-unit is advantageously rectangular and / or square. These sub-units serve to stabilize the grid structure. In addition, they are advantageously sized so that they can be filled with paving stones. This is of course not to be understood as limiting, so that other filling materials, such as sand, gravel or bedding, are of course also conceivable. A further type of sub-unit is also formed. These have a convex curvature and a concave curvature. The two curvatures, which are formed by the corresponding struts, are advantageously opposite one another and connected to one another by two further webs running parallel to one another.

[0017] Finally, at least a third type of sub-unit is provided for guiding the supply line. This third type advantageously has a convex curvature, which is advantageously designed as a circular arc. A concavely curved strut is connected to each of the two free ends of the circular arc, with both concavely curved struts having a common end point. The sub-units are particularly advantageously designed such that they merge into one another. Thus, for example, the circular arc of the third sub-unit is at the same time a concavely curved strut of each of the two sub-units of the second type arranged adjacent to it.

[0018] In a further advantageous embodiment, the at least one passage opening in the outer frame and the at least one passage opening in a longitudinal strut or transverse strut extend vertically from bottom to top. This is advantageous because at least one supply line can be arranged through these passage openings, at least in sections, in a space-saving and crush-free manner.

[0019] In a further advantageous embodiment, the passage openings are curved. This is advantageous because the at least one supply line, which is led at least partially through the passage openings, has a round cross-section. This allows for a precise fit of the at least one supply line.

[0020] A supply line is advantageously understood to mean a line that carries or can conduct electricity, data, and / or water. This also includes empty conduits.

[0021] In a further advantageous embodiment, the sub-units of the second and third type have passage openings. These are also advantageously arranged in the longitudinal direction and / or transverse direction such that the at least one supply line, which can be introduced later, can be laid without kinks in the longitudinal direction and / or transverse direction. Thus, the passage openings are advantageously designed to be aligned with one another in a transverse direction. Thus, the passage openings are advantageously designed to be aligned with one another in a longitudinal direction. As a result, several tunnel shapes can be formed in the longitudinal direction and / or transverse direction. This creates a high degree of flexibility for the at least one supply line that can be arranged later.

[0022] This is advantageous because it allows at least one supply line to be arranged beneath a flatly laid composite without impairing its function. The additional openings can therefore also be advantageously understood as guides and / or receptacles for possible supply lines. Naturally, this is not limited to irrigation lines; it can also encompass any type of line, such as power lines or empty conduits, which can later be filled with data cables or power cables.

[0023] In a further advantageous embodiment, at least one projection is arranged above the at least one passage opening of a sub-unit of the second and / or third type. This at least one projection is advantageous because it can be used to couple at least one supply line to the plastic grid multi-purpose module. In the simplest case, the at least one projection is designed to protrude horizontally. Particularly advantageously, only the sub-units of the third type have at least one, advantageously four, mutually opposite projections.

[0024] In a further advantageous embodiment, the projection is additionally supported by vertically extending support elements arranged laterally thereon. This advantageously ensures additional stability when forces are applied to the projection.

[0025] In a further advantageous embodiment, two opposing projections are configured with different sizes in their horizontal extension. This is advantageous because it allows the at least one supply line to be coupled particularly quickly via at least one line guide means.

[0026] Furthermore, the present invention also relates to a plastic multi-purpose system for forming a planar composite with at least one cable guide means and at least one plastic grid multi-purpose module, as described above, wherein the at least one cable guide means can be coupled at least in sections to at least one of the projections. This is advantageous because it can thus be mounted in a particularly simple manner, for example directly on the

[0027] Construction site, the cable guide from below into the

[0028] A plastic mesh multi-purpose module can be inserted and coupled via the projections. The cable guide serves to accommodate at least one supply line.

[0029] In a further advantageous embodiment, the at least one cable guide means has a coupling means on at least one free end, so that a positive connection and / or a non-positive connection is formed with the at least one projection in the use position. This coupling is advantageously reversible, so that it is also possible to separate the cable guide means from the plastic grid multi-purpose module again. This is advantageous because the at least one coupling means can form a secure and reliable connection between the cable guide means and the projection of the connecting struts. In one embodiment, the free ends of the cable guide means can be detachably coupled to the projections via a click connection. The at least one cable guide means is advantageously inserted from below.

[0030] The use position is advantageously understood to mean the position when the at least one line guide means has received a supply line and is coupled to it on at least one, advantageously on two mutually opposite projections, via a positive connection and / or frictional connection.

[0031] In a further advantageous embodiment, the coupling means can be designed as a projection. For this purpose, the coupling means is advantageously designed as a nose-like extension. The bevel provided here serves for easy insertion into the cylindrical hollow body of the second type. The horizontal line adjoining the bevel serves for fixation and is advantageously gripped by the projection in a use position. Thus, a detachable but very stable coupling can be achieved.

[0032] In a further advantageous embodiment, the at least one cable guide means is U-shaped. This is advantageous because the U-shaped curvature of the base allows at least one supply line to be accommodated securely and stably. Supply lines generally have a round cross-section, so that the base of the U-shaped cable guide means is also advantageously curved. In use, the base forms at least one common contact surface with the at least one supply line.

[0033] This is, of course, not to be understood as limiting; it is also conceivable for the base to have a flat profile, i.e., not be curved. This is the case, for example, if at least one rectangular cable duct is provided as the supply line. This, too, can be coupled with a plastic mesh multi-purpose module if appropriately designed.

[0034] In a further advantageous embodiment, two legs are designed to be increasingly spaced apart from one another as they extend towards a respective free end. One leg adjoins each end of the U-shaped base. Both legs extend in the same direction. In an advantageous embodiment, the distance between the legs changes. For example, the distance between the legs is greater at the free ends of the two legs than near the base. This is advantageous because it provides additional mobility of the legs. The coupling to the at least one projection of the cylindrical hollow body of the second type can thus be improved and carried out with reduced force application.

[0035] In a further advantageous embodiment, the two legs are designed to be resilient at their free ends when force is applied. This is advantageously made possible by the U-shaped design.

[0036] In a further advantageous embodiment, the cable guide is made of plastic. This is advantageous because it results in a particularly lightweight component. Furthermore, it can be easily manufactured, for example, by injection molding or 3D printing. The plastic also proves to be corrosion-resistant and durable. In the simplest case, polyolefins such as polyethylene and / or polypropylene can be selected for this purpose.

[0037] This is advantageous because it allows the cable guide to be given a resilient property. The two free ends then each have a nose-like extension on the legs. If a laterally acting compressive force is then exerted on the two free ends of the U-shaped cable guide, the two ends are brought towards one another. This makes it possible to feed the cable guide from below into the plastic grid multi-purpose module. More precisely, it is possible to guide the cable guide between two opposing projections of a cylindrical hollow body of the second type. If the compressive force is then removed, the restoring force causes the free ends to move away from one another again. This advantageously creates at least one positive connection and / or non-positive connection with the projections of the hollow body of the second type.Advantageously, the projections of the hollow body of the second type engage below the horizontal projections of the nose-like extensions of the free leg ends, thus creating a secure but reversible attachment. Subsequently, it is possible to pass at least one supply line through the thus created tab.

[0038] This is, of course, not to be understood as limiting, so that it is also conceivable that the at least one supply line is already partially inserted into the at least one line guide means before the reversible fastening thereof. The particularly advantageous provision of the projections of the cylindrical hollow body of the second type creates a high degree of individuality and flexibility, so that several supply lines can be reversibly arranged on the underside of the plastic multi-purpose module as required, thus forming a plastic multi-purpose system.

[0039] In a further advantageous embodiment, the plastic grid multi-purpose module further comprises at least one supply line. In an advantageous embodiment, the at least one supply line is designed as a water pipe or drip hose. This is advantageous because it allows irrigation and / or drainage to be provided. It has also proven particularly advantageous if the at least one supply line is designed to be at least partially or sectionally permeable to water. This makes it possible, on the one hand, to supply the ground area in which the plastic multi-purpose system is arranged with water. Due to the low-lying arrangement of the at least one

[0040] Supply line on the underside of the plastic grille

[0041] Multi-purpose module prevents unnecessary evaporation of the supplied water in warm or hot environments.

[0042] Provided water can rise upwards toward the surface of the plastic multi-purpose system via capillary action. This ensures a constant level of basic humidity while simultaneously providing significant protection against evaporation.

[0043] This is of course not to be understood as limiting, so that the at least one supply line described here can also be designed for drainage. If, for example, the plastic multi-purpose system is arranged so that it is at least partially submerged in water due to heavy rain, standing water from at least one plastic grid multi-purpose module can be drained away directly via the at least one supply line and the openings provided at least in some sections. This can advantageously prevent damage to buildings or road surfaces from becoming softened by heavy goods vehicles. It is also beneficial for plants as it prevents waterlogging. Excess water can be drained away, for example, using at least one coupled pump. This can advantageously suck water out of the at least one supply line at predetermined intensities and / or time intervals.

[0044] The low-lying arrangement of at least one supply line on the underside of the plastic multi-purpose system prevents unnecessary evaporation in warm or hot environments. This ensures a certain level of basic humidity while simultaneously providing significant protection against evaporation. In another advantageous embodiment, the frame is rectangular or square. The rectangular or square design has proven advantageous in that the plastic grid multi-purpose modules can then be installed particularly quickly and easily in a composite structure.

[0045] This is advantageous because it allows the surface composite to be formed from several plastic grid multi-purpose modules that can be arranged next to one another.

[0046] Individual plastic grid multi-purpose modules can be laid directly next to one another using this locking mechanism. The at least one outwardly extending coupling means of a first plastic grid multi-purpose module and the at least one lateral passage opening of a further plastic grid multi-purpose module arranged adjacent to it make it possible to connect several plastic grid multi-purpose modules to one another in a displacement-proof manner, thus creating a surface composite. This is advantageous because it prevents an individual plastic grid multi-purpose module from tipping over and can provide a highly stable, durable surface composite shape. The lateral passage opening advantageously serves to at least partially accommodate the respective opposite coupling means.

[0047] A quick and easy way to produce a surface composite from several interconnected plastic grid multi-purpose modules is to provide, for example, two plastic grid multi-purpose modules. Advantageously, both plastic grid multi-purpose modules have passage openings in the outer frame and, at the same time, offset coupling means extending outwards. The two plastic grid multi-purpose modules are then positioned so that one frame side with passage openings faces a frame side with coupling means. The plastic grid multi-purpose module with the passage openings is then guided over the coupling means of the other plastic grid multi-purpose module and / or the coupling means are inserted into the passage openings from below and locked into place by applying force.Advantageously, the coupling means are arranged at least partially within the passage openings. Particularly advantageously, one coupling means is placed at least partially within each passage opening. This positive and / or non-positive connection creates a highly stable surface composite that is tilt-proof and non-slip.

[0048] In a further advantageous embodiment, the at least one coupling means is hook-shaped. In the simplest embodiment, the hook shape can also be T-shaped. To form the corresponding surface connection, a T-shaped coupling means of a first plastic grid multi-purpose module can be introduced into a passage opening of a further plastic grid multi-purpose module arranged adjacent to it and connected to this in an advantageous locking position. For this purpose, both the T-shaped coupling means and advantageously the wall of the passage opening each have a corresponding projection which, after coupling, engage over and / or under one another and thus form a positive and / or non-positive connection.This prevents unwanted slipping out and dissolution of the surface composite, which can be formed by several plastic grid multi-purpose modules described here.

[0049] Furthermore, it has proven advantageous for rapid drainage if the plastic grid multi-purpose module is open at the bottom and advantageously does not have a closed bottom. It is particularly advantageous if the bottom is completely absent or has openings so that any accumulated water can be drained directly into the surrounding soil.

[0050] The variants of the plastic grid multi-purpose module described here can advantageously be manufactured in different weights. The material weights are advantageously based on the intended use. For example, if an installation assembly with plastic grid multi-purpose modules is to be laid in fire service access routes, the requirements for this are heavy-duty plastic grid multi-purpose modules. Consequently, the modules will have a higher material weight and thicker walls than if they were installed on the roof. In this case, lightweight plastic grid multi-purpose modules would be used, which are lighter and have thinner walls. Furthermore, the plastic grid multi-purpose modules described here can also have different heights.

[0051] Different heights are necessary, for example, if the terrain has a stepped shape or if lateral step boundaries are required when laying the tiles.

[0052] Furthermore, the present invention relates to a planar installation assembly with at least two plastic multi-purpose systems, which are connected to each other via coupling means and passage openings. Furthermore, the present invention also relates to the

[0053] Use of a plastic grid multi-purpose system as a modular component of a surface network, in use as a floor covering for driveways with heavy loads or driveways subject to particularly high stress, such as shunting areas in industrial buildings or commercial properties, as a modular component of a surface network for roof areas, as a modular component of a surface network in roof greening, as a modular component of a surface network in the floor area, as a modular component of a surface network for the irrigation of equestrian facilities, riding halls, riding arenas, livestock stables both indoors and outdoors.

[0054] Particularly advantageous is the flat composite of a variety of plastic multi-purpose systems laid over a large area. The plastic grid multi-purpose modules used for this purpose are connected to one another by the coupling mechanism described above. Due to the special geometry of the plastic grid multi-purpose module, it can also be used in escape routes, parking lots, roadways subject to high and heavy loads, or even in fire service access routes. With at least one pipe routing system, these access routes can also be irrigated underground and will no longer silt up in hot temperatures.

[0055] The same applies to the use of the lightweight construction on roof surfaces. Here, too, permanently greened surfaces can be provided. Furthermore, in a further embodiment of the plastic grid multi-purpose module, this can be designed with an additional irrigation function. This is advantageous because the at least one supply line, which can be laid without crushing through the openings in the connecting struts and / or through the openings in the connecting webs, allows green roofs that are particularly susceptible to drought to be supplied with sufficient moisture quickly and easily. Here, too, it is advantageous that the at least one supply line does not run directly on the tread surface, but rather at a depth of 4-35 cm.

[0056] Particularly advantageous for this purpose is at least one plastic grid multi-purpose module, more advantageously several plastic grid multi-purpose modules, coupled together as a flat composite, each having at least one cable routing means, at least partially filled with soil or other filling material and / or covered with soil or other filling material to a depth of 5-25 cm. This provides sufficient soil material for planting and for additional fastening. This allows moisture to be provided from below, which can spread upwards via capillary action. This makes it possible to water green roofs indirectly, so that they remain attractively green even in summer or in particularly dry regions, without too much water being wasted through direct irrigation. At the same time, it is possible to provide a substrate with a predeterminable moisture content.This can also prevent cracks and hardening of the soil. It has proven particularly advantageous if the soil moisture is recorded by at least one sensor and the irrigation intensity is regulated accordingly by at least one control unit. At the same time, the plastic multi-purpose system described here makes it possible to drain standing water on roofs in the event of heavy rainfall. This can be done, for example, using at least one additionally connectable pump which actively pumps out the standing water via the laid pipes once a pre-determined water level is reached. For this purpose, too, at least one sensor which records the water level can advantageously be provided.

[0057] Furthermore, the plastic multi-purpose system described here can also be used as a single foundation for posts, preferably made of wood or plastic, fence posts, preferably made of wood or plastic, sign poles, preferably made of wood or plastic, and / or roof structures made of metal or the like. This also provides an additional use. This can be used, for example, when sunlight is to be used to generate electricity using suitable modules, and these must be attached to roofs.

[0058] It is also conceivable that plastic multi-purpose systems could be used in a wider range of areas. It has proven particularly advantageous to use the plastic multi-purpose system as a surface-mounted assembly for the irrigation and / or drainage of equestrian facilities, riding arenas, indoor riding arenas, livestock stables or riding arenas, both indoors and outdoors. In equestrian sports in particular, it has been common practice to moisten riding facilities using the so-called "ebb and flow" method. This involves flooding sand arenas, for example, with water to prevent dust from forming on hot, dry days. At the same time, this watering makes the sand firmer, giving the horses a sure footing and making riding easier on the horses' joints. This method is disadvantageous in that it constantly uses up a lot of water and does not provide a permanently, evenly moist surface.With the modular plastic grid multi-purpose module described here, which can optionally be supplemented with at least one water pipe and which can be laid as a flat composite, it is possible to provide a constant, permanent soil moisture.

[0059] When used for this purpose, it has proven advantageous if the plastic grid multi-purpose module is laid in the ground, for example at a depth of 4 - 15 cm. It is advantageous to fill with sand directly above the plastic grid multi-purpose module to create a sand footing for the horses. This can advantageously be 4 to 30 cm, or even more advantageously 4 to 15 cm thick. If watering is carried out from below via several, optionally interconnected plastic grid multi-purpose systems, preferably with several water supply lines that are linked via line routing, it is possible to keep the sand footing permanently moist from below in order to provide the best possible training surface for the horses. It is also particularly advantageous here that the soil moisture can be recorded by at least one sensor and regulated by at least one control unit.Furthermore, it has proven particularly advantageous to install the flat-laying plastic grid multi-purpose module described here directly in the ground without any additional tools. No further protection of the supply lines is necessary, as these are already inserted into the underside of the plastic grid multi-purpose modules and thus secured by the cable routing devices. It is therefore possible to lay the plastic grid multi-purpose system described here in a flat composite, with the supply lines already pre-assembled. During final assembly, the supply lines are then connected to one another to create a closed pipe network. Irrigation can also be additionally supported by at least one pump, which is particularly advantageous.

[0060] It has proven particularly advantageous if the plastic mesh multi-purpose module is made at least partially, preferably entirely, from plastic, even more preferably from thermoplastic. Examples of this are advantageous olefins, such as polypropylene and / or polyethylene.

[0061] The plastic used can, for example, be unprocessed, recycled, fiber-reinforced, filled in some other way, for example with nanoparticles, biodegradable, and / or mixtures and / or combinations thereof. In the simplest case, acrylonitrile butadiene styrene, polyamide, polyethylene, or polypropylene are used.

[0062] To achieve sufficient stabilization of the plastic grid multi-purpose module described here once installed, it has proven advantageous to fill the resulting chamber-like structures with free-flowing material. In the simplest case, this could be soil. It is also conceivable to use other free-flowing materials, such as stones, sand, gravel, or mixtures thereof. Alternatively, paving stones or other concrete blocks can be used in the square sub-units.

[0063] The plastic grid multi-purpose module described here has a significantly larger geometric extension, which is particularly advantageous but not limiting. It can also be referred to as an XXL plastic grid multi-purpose module. The plastic grid multi-purpose module is advantageously larger in its longitudinal extension than in its transverse extension. The plastic grid multi-purpose module of the plastic multi-purpose system is particularly advantageous in the range from 80 cm to 200 cm, more advantageous from 100 cm to 135 cm long. The plastic grid multi-purpose module of the plastic multi-purpose system is particularly advantageous in the range from 40 cm to 150 cm, more advantageous from 80 cm to 110 cm wide. The plastic grid multi-purpose module 100 cm ± 5 cm wide and 135 cm ± 5 cm long is particularly advantageous.

[0064] Further advantages, features and design options emerge from the following description of non-limiting embodiments.

In the following, the reference symbols will not be repeated for all elements already introduced and illustrated, provided that the elements themselves and their function have already been described or are known to a person skilled in the art.

[0077] Detailed description of working examples

[0078] Figure 1 shows a top view of a plastic grid multi-purpose module 100. This has a circumferential outer frame 102. Numerous T-shaped coupling means 104 are arranged on this outer frame 102 and also extend outwards. The outer frame 102 is tensioned by numerous struts, advantageously longitudinal struts 106 and transverse struts 108, which can also be arranged diagonally and / or non-linearly. Advantageously, at least three different sub-units 120, 122, 124 are formed. Advantageously, the sub-unit 120 is square. Advantageously, the second sub-unit has a convex curvature and a concave curvature. Advantageously, the two curvatures, which are formed by the corresponding struts 106, 108, are opposite one another and are connected to one another by two further webs running parallel to one another.Advantageously, the third subunit has a convex curvature, which is advantageously formed as a circular arc. A concavely curved strut adjoins each of the two free ends of the circular arc, with both concavely curved struts 106, 108 having a common end point.

[0079] Furthermore, at least in sections, the longitudinal struts 106 and transverse struts 108 have at least one projection 110, 112. Particularly advantageously, the projections 110, 112 are arranged opposite one another, so that advantageously a total of two projections 110 and two projections 112 are arranged in each section. Advantageously, the projections are arranged in the third subunit 124. Even more advantageously, the projections 110, 112 are formed horizontally.

[0080] Figure 2 shows the underside of the plastic mesh multi-purpose module 100 from Figure 1. Here, too, the projections 110, 112 are arranged in a visible manner.

[0081] Figure 3 shows an enlarged detail from Figure 1. It can be seen that here only some of the longitudinal struts 106 and transverse struts 108 have a passage opening 114. In this exemplary embodiment, this is curved. Furthermore, the passage opening 114 extends vertically upwards from the base side. This is advantageous because it allows a supply line (not shown) to be introduced from below. Furthermore, the projections 110, 112 are also shown, wherein it is clear that the projections 110, 112 are of different sizes in their support surfaces 110a and 112a. In order that the support surfaces 110a, 112a can be held and stabilized accordingly, side struts 116, 118 are also provided. These can also be referred to as support elements.Furthermore, it is ensured that the passage openings 114 are freely accessible and are neither blocked nor restricted in their passage by the side struts 116, 118 nor by the support surfaces 110a, 112a.

[0082] Figure 4 shows a plastic multi-purpose system 200 with a plastic grid multi-purpose module 100 and two supply lines 202 in plan view.

[0083] Figure 5 shows a plastic multi-purpose system 200 with a plastic grid multi-purpose module 100 and two supply lines 202 in a bottom view. This bottom view also shows the two line guides 204. These serve to fix the two supply lines 202 to the plastic grid multi-purpose module 100. For better understanding, an enlarged section of this is shown in Figure 6. The line guides 204 are in positive and / or force-locking engagement with the projections 110, 112. This allows the supply lines 202 to be positioned accordingly and also held securely.

[0084] Figure 7 also shows an enlarged, perspective sectional view of a plastic multi-purpose system 200. The passage openings 114 are still free and are framed here, for example, by the support surface 112a and the side struts 116. On the right-hand side, a supply line 202 is shown, which is held by the line guide means 204. The line guide means 204 is positively and / or non-positively connected to the support surface 112a of the projection 112 via its two nose-like extensions 208. The same also applies to the projection 110, which is arranged opposite and is not separately shown here. The nose-like extension 208 is additionally held by the side struts 116, since the side struts 116 extend vertically beyond the support surface 112a and thus form lateral boundaries. The cable guide means 204 is U-shaped here.It has a curved base 210. This base 210 advantageously forms a common contact surface, at least in sections, with the supply line 202 that can be arranged therein. The supply line 202 lies on the base 210 and is held by the latter. Two legs 212, 214 extend upwards from the curved base 210. Both legs 212, 214 each have a free end 216, which is also designed as a coupling means 218. Furthermore, it is shown that the legs 212, 214 diverge in the direction of their free ends 216. The U-shape is widened. This widening is advantageous because it allows the legs 212, 214 and in particular the coupling means 208 to have a resilient property. The coupling means 208 are designed as nose-like projections. They have, on the one hand, a downwardly directed slope, which then merges into a horizontal boundary.The bevel is advantageous for the easy insertion of the two coupling means 208 from below. The coupling means 208 are subjected to force by the insertion and slide particularly easily past the projections 110, 112 due to the bevel. Here, an additional force can act on the coupling means 208. The legs 212, 214 are moved towards one another. When the projections 110, 112 are passed over, the legs 212, 214 reset so that the coupling means 208 are guided outwards. In this case, they are already gripped by the projections 110, 112 and are held in the click position. In this way, an easily carried out, releasable fixation of the supply line 202 can be provided.

[0085] To remove the line guide means 202, the legs 212, 214 are again subjected to a force, advantageously a compressive force, so that the nose-like extensions 208 are guided away from the projections 110, 112 and, in the compressed state, are removed from the sub-unit of the third type 124.

[0086] Although the invention has been illustrated and described in detail by the advantageous embodiments, the invention is not limited by the disclosed examples. Other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention. In particular, the invention is not limited to the feature combinations specified below, but other combinations and sub-combinations that are obvious to the skilled person can also be formed from the disclosed features.
