Description

[0001] The invention relates to a cable ladder system, which is used in particular for guiding electrical cables or lines, e.g. from a photovoltaic (PV) system on a roof, for example a flat roof of an industrial building.

[0002] These electrical cables or wires are typically used to connect a photovoltaic (PV) system to an inverter on the outside of a building, running from the roof down. However, existing solutions often present installation problems, particularly when spanning roof overhangs such as gutters. Current solutions exhibit shortcomings in terms of ease of installation and functionality, and frequently result in high costs.

[0003] Conventional cable management systems often require complex assembly steps, are not standardized, and result in inadequate cable routing, which can impair cable lifespan. Furthermore, they are susceptible to environmental factors such as UV radiation, which reduces cable longevity.

[0004] Against this background, the object of the invention is to provide a cable ladder system that is easy to install, enables load-free cable routing and reduces costs and maintenance through standardized elements.

[0005] This problem is solved by a cable ladder system for cables and / or wires with at least one first cable ladder segment having two spaced-apart first ladder stiles and several ladder rungs connecting the two first ladder stiles, wherein the ladder rungs form a first guide plane for the cables and / or wires, and wherein the cable ladder segment is designed to be attachable to a building wall;a second cable segment designed to be connectable to the first cable segment, comprising two spaced-apart second conductor rails and several conductor rungs connecting the two second conductor rails, the conductor rungs forming a second guide plane for the cables and / or wires, the second guide plane having a first section extending at an obtuse angle to the first guide plane and a second section adjoining the first section and being arc-shaped, the second guide plane being substantially perpendicular to the first guide plane at its end.

[0006] This system offers flexible and adaptable installation, especially on building walls. The arched design facilitates spanning roof overhangs and ensures tension-free cable routing.

[0007] The problem is thus completely solved.

[0008] In a preferred further development, at least one cable line cover is provided which can be connected to the conductor rails of the first and / or second segment and runs parallel to the guide plane, forming an interior space between the cover and the guide plane.

[0009] The cover provides protection against weather conditions such as UV radiation and allows for easy installation of cables indoors.

[0010] In a preferred further development, the cable conduit cover in the area of ​​the arc-shaped section of the second guide level consists of u-shaped segments that are connected and angled to form the arc shape.

[0011] This design facilitates adaptation to different roof shapes and overhangs and enables stable and secure cable routing even in difficult environments.

[0012] In a preferred further development, the second ladder stiles each have a substantially pentagonal section and an arc-shaped section, wherein the long side of the pentagonal section can be connected to one of the first ladder stiles.

[0013] The pentagonal shape of the ladder stiles allows for easy connection with the other segments and increases the stability of the system when installed over roof overhangs.

[0014] In a preferred advanced training method, the second ladder stiles are each formed in one piece.

[0015] The one-piece construction of the ladder stiles reduces the number of connecting elements required and increases the strength and durability of the system.

[0016] In a preferred further development, a third side of the pentagonal section runs at right angles to the long side, while the fourth side runs at an acute angle to the long side.

[0017] The angled design of the spar ensures improved fit and facilitates installation, especially with different roof structures.

[0018] In a preferred further development, the first and / or second ladder stiles have a series of holes for attaching the ladder rungs and the cable ladder cover.

[0019] The pre-drilled holes allow for flexible and quick assembly, which reduces installation time.

[0020] In a preferred further training method, the ladder rungs have a C-shaped or U-shaped cross-section.

[0021] The C- or U-shaped design of the ladder rungs improves the stability of the cable tray while also allowing for easy handling during installation. This reduces the risk of cable damage and facilitates the insertion and removal of cables.

[0022] In a preferred further development, the second ladder stiles are plate-shaped.

[0023] The flat design of the ladder stiles allows for a particularly space-saving and flat installation on building walls or other surfaces, which improves the visual appearance and reduces material costs.

[0024] In a preferred further development, at least a third cable line segment is provided, which is designed to be pivotably attached to the end of the second cable line segment and has two third conductor rails and at least one conductor rung that connects the two conductor rails.

[0025] The swiveling connection of the third segment increases the system's flexibility, especially in situations where a change in cable direction is necessary. This facilitates installation in complex environments.

[0026] In a preferred further training, the two third ladder stiles and at least one ladder rung are formed in one piece.

[0027] The one-piece design of the third ladder stile and ladder rung reduces the number of connection points and increases the stability of the entire system, thereby simplifying assembly and reducing maintenance costs.

[0028] In a preferred further development, the third ladder stiles have a series of holes arranged in an arc shape, allowing attachment to the second ladder stile in different angular positions.

[0029] The arc-shaped arrangement of the holes offers flexibility in adapting the cable routing. This increases the system's versatility and allows for precise adaptation to the specific environment.

[0030] In a preferred further training, at least two third cable line segments are provided and connected to each other.

[0031] By using multiple third segments, the cable ladder system can be adapted for longer distances or more complex routes. This increases modularity and enables wider application in larger installation areas.

[0032] In a preferred training method, the ladder stiles and rungs are made of metal.

[0033] The metal construction gives the cable ladder system high strength and resistance to external influences such as weather and mechanical stress. This ensures a long service life for the system and minimizes maintenance requirements.

[0034] The problem underlying the invention is also solved by a cable conductor segment for the cable conductor system according to the invention, wherein the cable conductor segment has two spaced-apart second conductor stiles and several ladder rungs that connect the two second conductor stiles to each other, wherein the ladder rungs form a second guide plane for the cables and / or conductors, and the second guide plane has a first section that extends at an obtuse angle to the first guide plane, and a second section that adjoins the first section and is curved, wherein the second guide plane is essentially perpendicular to the first guide plane at the end.

[0035] The cable conduit segment, with its special angled and curved structure, enables precise and stable cable routing across various inclines and transitions. This improves cable strain relief and allows for flexible adaptation to the specific building environment.

[0036] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0037] Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawing. These show: Fig. 1. A schematic representation of a cable ladder system in perspective view; and Fig. 2 A side view of the second cable segment.

[0038] In Fig. Figure 1 shows a section (in the area of ​​the transition from wall to roof) of a cable ladder system and is labelled with reference numeral 20. Such a cable ladder system is generally used to route lines and cables, especially electrical lines, from one location to another on a building. For example, cable ladder system 20 can be used to route electrical lines from a photovoltaic system on a roof to other electrical components, such as inverters, in the lower part of the building.

[0039] For example, in Fig. Figure 1 shows an exterior wall 12 of a building 10 and a section of a roof surface, here exemplified by a flat roof 14. At the transition between the flat roof 14 and the exterior wall 12, a rain gutter 16 is provided, for example. This rain gutter 16, representing any type of overhang, projects from the exterior wall 12. Such an overhang can also take the form of a parapet, i.e., a projection beyond the roof surface. Such overhangs must accommodate a pipe or cable that is to be laid downwards from the flat roof 14. The cable ladder system 20 is provided for this purpose.

[0040] The cable ladder system 20 consists of at least two cable conductor segments 30, 40. While the cable conductor segment 40 overcomes the overhang caused by the rain gutter 16, the other cable conductor segment 30 serves to continue the cables or conductors downwards parallel to the outer wall 12.

[0041] The first cable segment 30 comprises two parallel first conductor strings 32, which are formed, for example, from C- or U-shaped elements. The first conductor strings 32 are detachably connected to each other via conductor rungs 34, wherein in Fig. Figure 1 shows only one ladder rung 34. It is understood that several ladder rungs 34, evenly or unevenly distributed, can be provided along the length of the first cable conductor segment 30.

[0042] The first ladder stiles 32 have holes 80 evenly spaced along their length. The ladder rungs 34 of the first cable segment 30 form a first guide plane 36 in which the cables or wires run. This first guide plane 36 runs parallel to the outer wall 12 when the cable ladder system 20 is firmly attached to the house wall 12. The cables or wires can, for example, be attached to individual ladder rungs.

[0043] Although the first cable segment 30 in Fig. 1 consisting of two one-piece manufactured first ladder stiles 32, it is understood that the respective ladder stiles can also be constructed from individual components joined together.

[0044] The second cable segment 40, which is also detailed in Fig. 2 is attached to the first cable ladder segment 30 and extends over the overhang caused by the rain gutter 16 into the area of ​​the flat roof 14.

[0045] The second cable segment 40 has two second conductor rails 42, which are arranged parallel to each other and connected to each other via ladder rungs 44. The several ladder rungs 44 form a second guide plane 46, which in the lower area initially runs diagonally away from the outer wall at an acute angle, then has an arc-shaped section to pass over the rain gutter 16 and finally ends parallel or substantially parallel to the flat roof 14.

[0046] The two second ladder stiles 42 are essentially plate-shaped and each has a first section 70 and a second section 72. The lower first section 70, which is separated from the second section 72 in the Fig. 2, separated by an imaginary and dashed line, has a pentagonal structure with a long side 74, which ends at the end of the second ladder stile, a shorter side 76 opposite, which lies in the transition area to the second section, and an upper side 77 running perpendicular to the long side 74. The opposite side 78 is divided into a first section, which runs perpendicular to the long side 74, and a second section, which runs obliquely upwards (at an acute angle to the long side 74).

[0047] The second section 72 is curved, with the curve extending over an angle of 180°. The shape of the curve is adapted to the usual geometry of a rain gutter 16, such that the height H and the depth T of a recess 79 are chosen to be greater than the height and the depth of the rain gutter 16.

[0048] As can be seen from Fig. 2 results in this arc-shaped section ending almost horizontally, so that the second guide level allows a good transition to the roof 14.

[0049] In particular, the second arc-shaped section has two rows of holes 80, 82, both of which also have an arc-shaped course. The inner row of holes 80 serves to fasten the ladder rungs, while the outer row of holes 82 serves to fasten a cover.

[0050] It should be noted that the arc-shaped orientation of the internal holes is an essential aspect of the cable ladder system 20, enabling the cables or wires to be guided neatly in the arc-shaped guide plane. The arc-shaped design of section 72 is a preferred embodiment; however, this section could also have a different shape, as long as the holes provided for fastening the ladder rungs are arranged in an arc.

[0051] Out of Fig. Figure 2 shows that an eye 84 with a mounting hole 80 is provided at the upper end of the second section 72. This eye 84 serves to fasten a third cable segment 50, which is located in Fig.As can be seen in Figure 1, this third cable segment 50 is attached to the opposing eyes 84 of the two second conductor rails and can be pivoted about an axis. Holes 58, also arranged along a circular arc, are provided for the final fixing of the third cable segment 50. In other words, the third cable segment 50 can be fixed at different angular positions relative to the second cable segment 40.

[0052] This third cable segment 50 also consists of two parallel third conductor spars 54, which are connected to each other via one or more conductor rungs 54. These conductor rungs 54 in turn form a third guide plane 56. In the present embodiment, this third guide plane 56 is flat, i.e., not curved like the second guide plane 46.

[0053] As briefly mentioned earlier, the cables or wires are laid on the ladder rungs and preferably attached to them, or at least to some of them. The arc-shaped second guide plane 46, which runs around the rain gutter 16, has a geometry that prevents any kinking of the wires. The second guide plane must therefore have an arc-shaped geometry that guides the cables or wires from a horizontal to a vertical position without excessive changes in direction.

[0054] To protect against external weather influences, e.g., UV radiation from the sun, cable conduit covers 60 (60.1, 60.2) are provided. These cable conduit covers 60 are attached to the conductor stiles 32 and 42. The cable conduit cover 60.2 assigned to the second cable conduit segment 40 is designed to conform to the curved shape. For this purpose, the essentially U-shaped cable conduit cover 60, here 60.2, is divided into individual segments that can be bent or angled relative to each other to a certain extent. This angling can be achieved, for example, by thinning the material to create a bending edge.

[0055] The cable cover 60, here 60.1, assigned to the first cable segment 30, is also U-shaped, however, no bending edges need to be provided here, since the first cable segment 30 extends in one plane.

[0056] The components of the cable ladder system 20 are preferably made of metal in order to achieve high weather resistance.

[0057] The previously described cable ladder system 20 is therefore modular in design and comprises only a few components that must be available for assembly. Thus, it is sufficient to provide several different second cable conductor segments 40 with varying arc shapes with respect to height H and depth T in order to overcome the usual dimensions of rain gutters or overhangs in general. This modular system therefore significantly simplifies the construction of the cable or conductor routing.
