Description

[0001] The invention relates to a cable routing system for laying cables according to the independent claim.

[0002] The invention lies in the technical field of laying cables in cable ducts and cable shafts or trenches over long distances.

[0003] There are numerous different cables and wires for power supply or data transmission that need to be installed in various areas. Professional cable management solutions are essential to ensure that these cables are laid safely, clearly, in a space-saving and efficient manner.

[0004] Avoiding material damage is paramount in almost all cable installations, especially with sensitive data cables. Cable pulling is often further complicated by bends in the duct and differences in elevation. Cable guides facilitate cable laying, particularly over long distances in shafts and / or trenches.

[0005] In a well-known steel corner roller for cable and rope guidance in the trench, three steel sheet rollers with ball bearings and a plug-in system with a fastening nail each allow two or more corner rollers to be connected for optimal cable guidance.

[0006] For cable routing in shafts, there are, for example, threaded aluminum / stainless steel rollers that allow gliding or rolling in conduits, e.g., for fiber optic rods. The roller also features a connecting thread for adapting various guide rods, probes, cable pulling grips, etc.

[0007] Cable guide pulleys for cable routing in shafts are also available. These are particularly suitable for mounting on the shaft edge or steps to guide cables around corners gently and with minimal resistance. The two tabs ensure a right-angle stop. The cable guide pulley can be attached through the mounting hole using a strap or screws.

[0008] There are also threaded shackles for cable and rope guidance in shafts. The shackle is used to attach cables, pull wires, or winches.

[0009] Another well-known product is the Flexipass cable routing system, which uses smooth-running guide rollers at all corners and edges of cable trays to ensure safe and precise cable transfer. It is available in various designs for cables up to 38 mm in diameter. Particular attention has been paid to handling sensitive data and specialty cables. The clever arrangement of the rollers ensures optimal and resistance-free cable routing and transport. With its low weight of just 0.75 kg, the Flexipass cable routing system can be used even in lightweight cable trays without any problems.

[0010] However, a disadvantage of the known deflection products is that they are often complicated and time-consuming to assemble and disassemble.

[0011] The invention aims to provide a cable routing system that overcomes the disadvantages of the prior art and enables quick and easy installation and removal.

[0012] The problem is solved by a cable guide for laying cables with the features of independent claim 1. Advantageous embodiments are the subject of the dependent claims.

[0013] The invention comprises a cable guide for laying cables, comprising a housing with an insertion section formed by a first roller element for inserting at least one cable into the housing, an exit section formed by a second roller element and arranged opposite the insertion section for leading the cable out of the housing, a third roller element arranged transversely to the first and second roller elements on a first side of the housing, and a fourth roller element arranged transversely to the first and second roller elements and parallel to the third roller element on a second side of the housing opposite the first side. This allows the cable guide to be used easily and quickly by one person for laying one or more cables.

[0014] One advantageous feature is that the cable guide includes an opening for a fastener to attach it to a flat surface. This allows the cable guide to be screwed to and easily removed from any flat, solid surface such as concrete, wood, metal, as well as a mounting rail, cable tray, or wall bracket.

[0015] It is particularly advantageous if the roller elements are detachably arranged in the housing. This makes it easy to free cables that have become jammed during installation.

[0016] According to one preferred design, the roller elements are a ball bearing and / or a tube. This allows several cables to be pulled in parallel.

[0017] Advantageously, the opening is slot-shaped to allow engagement with the mounting bracket, which is a mounting hook. This enables the housing to be rotated 360° on the mounting bracket, thus reducing the force exerted on the surface to which the cable guide is attached during use.

[0018] It has proven advantageous if the insertion section includes at least one outward-facing guide element for inserting the cable into the insertion section. This facilitates the precise insertion of the cable into the insertion section.

[0019] An advantageous aspect is that the cable guide also includes a transport element that can engage with the roller elements for transporting the cable between them. In this way, cables can be pulled from point A to point B via all fastening points using a single cable guide.

[0020] It is particularly advantageous if the cable tray is made of steel. This allows for a very robust cable tray, characterized by high load-bearing capacity and stability.

[0021] According to a preferred design, a system for guiding and securing one or more cables comprises a cable guide and a fastening device for attaching the cable guide to a flat surface, the fastening device being a fastening hook. In this way, the system can be securely installed even on sloping surfaces made of concrete, wood, or metal, such as a roof, but also on a mounting rail, cable tray, or wall bracket.

[0022] Advantageously, the system includes at least two cable trays for routing cables. With such a system, cables can be pulled over long distances and around many corners.

[0023] The invention will now be explained in more detail with reference to a drawing. The drawing shows: Fig. 1 a schematic representation of a cable routing according to the invention for laying cables in a top view; Fig. 2 a schematic representation of a cable routing according to the invention for laying cables in a side view; and Fig. 3 A schematic representation of a fastening hook for attaching the cable guide to a flat surface.

[0024] Fig. Figure 1 shows a cable guide 1 according to the invention for laying cables, comprising a housing 2 with an insertion section 21 formed by a first roller element 31 for inserting at least one cable into the housing 2, an exit section 22 formed by a second roller element 32 and arranged opposite the insertion section 21 for leading the cable out of the housing 2, a third roller element 33 arranged transversely to the first and second roller elements 31, 32 on a first housing side, and a fourth roller element 34 arranged transversely to the first and second roller elements 31, 32 and parallel to the third roller element 33 on a second housing side opposite the first housing side. The roller elements 31, 32, 33, 34 are detachably arranged in the housing 2. The roller elements 31, 32, 33, 34 are each a ball bearing and / or a tube.

[0025] The cable guide includes an opening 23 for receiving a fastening element 4 for attaching the cable guide 1 to a flat surface. The opening 23 is slot-shaped to allow engagement with the fastening element 4, which is a fastening hook. This allows the cable guide to be easily hooked onto and detached from the fastening hook.

[0026] The insertion section 21 comprises at least one outwardly directed guide element 5 for inserting the cable into the insertion section 21.

[0027] It is also conceivable that the cable routing further includes a device (shown in dashed lines) through which a protective tube and / or a flexible hose can be inserted, in which the cable is laid, thus enabling cable routing with a protective tube and / or flexible hose.

[0028] In Fig. Figure 2 shows a side view of a cable guide 1 according to the invention. The cable guide 1 is made of steel.

[0029] The cable guide 1 comprises a transport element (not shown) that can engage with the roller elements 31, 32, 33, 34 for transporting the cable between the roller elements 31, 32, 33, 34. For example, the transport element is a wire rope to which the cable to be laid is attached. The roller elements 31, 32, 33, 34, with which the transport element engages, can each be driven by a standard cordless screwdriver. This allows the cable to be transported a distance to the next roller element 31, 32, 33, 34.

[0030] Fig.Figure 3 shows a fastening hook for attaching a cable guide 1 according to the invention to a flat surface, for example, a wall or a roof. The fastening hook serves equally well for attaching a cable guide 1 according to the invention to a flat and solid substrate such as concrete, wood, metal, as well as to a mounting rail, cable tray, or wall bracket.

[0031] This creates a system for guiding and securing one or more cables, comprising at least one cable guide 1 for laying cables and a fastening means 4 for attaching the cable guide 1 to a flat surface, wherein the fastening means 4 is a fastening hook.

[0032] It is also conceivable to have a system that includes at least two cable routing options for laying cables.
