Description

[0001] The present invention relates to a deflection device for a table cabling system for transferring several cables from the horizontal to a vertically arranged energy chain.

[0002] With the ever-increasing number of electronic devices placed on desks and the resulting need to route cables to specific locations, such as a floor outlet, there is also a growing demand for bundled cable management. Furthermore, since the devices are not always located in a single area on the desk, it is necessary not only to bundle the cables but also to route them in sections.

[0003] In this context, for example, the use of a cable duct under a desktop or on other pieces of furniture, as well as the use of cable guide chains for the targeted guidance and organization of cables or wires between two connection points for cable management, especially in the area of ​​workplaces, has long been known.

[0004] However, this usually requires separate fastening systems for the cable guide chains on the one hand and for the cable ducts on the other. On the other hand, this is also provided for. Changing systems generally does not guarantee that the cables can be quickly replaced along their entire length. At the same time, there is a risk that the cables will be loose or hanging freely in certain sections, leaving them unprotected.

[0005] The object of the present invention is to provide a deflection device for table cabling that enables structured and targeted routing of the cables and yet is characterized by a simple design.

[0006] This task is solved by a deflection device for a table cabling system to transfer several cables from the horizontal into a vertically arranged energy chain, with a substantially horizontal guide section and at least one deflection section adjoining it for deflection into at least one vertical guide section facing the energy chain.

[0007] The cable guide chain can be connected in a vertical direction or in a direction rotated by 90°.

[0008] The deflection device according to the invention thus enables the cables to be easily deflected from one guiding direction to a different second guiding direction. This allows the cables to be guided optimally, in particular without any impairment of the cables. The deflection device has a very simple structure and can therefore be manufactured cost-effectively, especially from plastic materials.

[0009] According to a preferred embodiment, at least two deflection sections are arranged one behind the other in the longitudinal direction of the deflection device, terminating in two vertical guide sections. This makes it possible to arrange several energy chains or power chains with the same orientation one behind the other on the deflection device.

[0010] The provision of two deflection sections enables a structured routing of the cables in the area of ​​the cantilever arm, so that the cables can already be directed into the energy supply chain.

[0011] According to another preferred embodiment, the deflection device can be part of a cantilever arm associated with a cable duct. The cantilever arm design has proven particularly effective in practice.

[0012] According to a preferred embodiment, the cantilever arm can comprise two side walls and a crossbar extending between them as a base, wherein a deflection section is formed by an end section of the crossbar that is at least partially rounded. The cantilever arm thus has an almost channel-like structure, which makes it possible to insert or remove cables at any time. The side walls ensure that the cables are guided and held securely within the cantilever arm. Furthermore, the rounded sections allow the cables to be guided in such a way that the minimum bending radius is not undercut.

[0013] According to another preferred embodiment, the deflection sections can be rounded and arranged parallel to one another. It has proven particularly advantageous if the deflection sections have a bending radius that is not less than the minimum bending radius of the cables being deflected. The special structuring of the cantilever arm in the present invention makes it possible to transfer the cables from a side-by-side position to a position that is first stacked on top of each other and then one behind the other. This guidance allows the cables to be easily guided from one guide path to the next.

[0014] Another preferred embodiment provides that the deflection sections facing away from the cable duct are formed by two support sections spaced apart from each other by a slot-shaped opening. By forming a slot-shaped opening in the area of ​​the deflection section located on the side facing away from the cable duct, it is possible to insert the cables into any part of the cantilever arm without difficulty and without having to unhook them before insertion. If an additional end face is provided on the side facing away from the cable duct, which connects the side walls, this end face can also be designed with a slot.

[0015] To hold the cables on the support sections, retaining sections can be arranged on the edges of the support sections opposite the slot-shaped opening.

[0016] According to a further preferred embodiment, the crossbar in the area of ​​the first guide section can rise at a predetermined angle, at least in sections. This embodiment makes it possible to design the cantilever arm more compactly, since the rounded deflection sections are arranged entirely within the cantilever arm, allowing the cantilever arm to maintain a low height. In longitudinal section, the crossbar has an almost wave-like shape along its entire length. This shape of the crossbar further aids in guiding the cables.

[0017] Another preferred embodiment provides that the cantilever arm has two chamber sections, each comprising a substantially horizontal guide section and two adjoining deflection sections arranged one behind the other in the longitudinal direction of the cantilever arm. The design of two separate chambers further serves to guide the cables within the cantilever arm in a structured manner. Here, too, several guide paths are provided, allowing cables to be routed from one guide path to the next.

[0018] The cables are held between the side walls and the central support or the retaining bridge, ensuring they are guided securely.

[0019] Preferably, the chamber sections can be separated from each other by a central web arranged parallel to the side walls on the crossbar. Providing a central web represents a very simple embodiment for forming two chambers. This embodiment also facilitates the cost-effective manufacturing of the cantilever arm.

[0020] Furthermore, it proved preferable to have at least one retaining rib formed on a side wall. Two retaining ribs can be arranged opposite each other, forming a slot. Preferably, the at least one retaining rib is arranged on an upper edge of the side wall. Corresponding retaining ribs additionally secure the cables inside the cantilever arm. According to an additional embodiment, a cover element can also be provided, which completely closes the cantilever arm at its upper side.

[0021] In this context, it has proven particularly advantageous to arrange the retaining clips before the first deflection section. The cables are held securely, especially in the area where the transition from near-horizontal to vertical guidance occurs.

[0022] According to another preferred embodiment, the cantilever arm can have fastening means for the energy chain in the area of ​​the second guide section. These fastening means are preferably arranged inside the cantilever arm, for example on the side walls, and enable very simple coupling of the energy chain to the cantilever arm.

[0023] It has proven particularly advantageous if fastening means for securing the energy chain are designed parallel to or transverse to the longitudinal direction. A correspondingly designed cantilever arm is therefore particularly flexible in its application; that is, it is not necessary to decide in advance in which direction the energy chains are arranged, but rather the cantilever arm according to the invention allows the direction of the energy chain to be determined only after the cantilever arm has been fixed.

[0024] Preferably, two parallel energy chains can be attached. Sufficient fastening means are provided to allow the parallel energy chains to be fixed both longitudinally and transversely.

[0025] Another preferred embodiment may provide that the cantilever arm further comprises a fastening section for fastening the cantilever arm in or to the cable duct.

[0026] Preferably, fixing elements can be arranged on the underside of the fastening section, which interact with complementary fixing elements in the area of ​​the cable duct base. Such a fastening method has proven particularly effective in practice, as it allows for optimal force distribution.

[0027] According to a preferred embodiment, the fixing means can be locking elements and receiving openings. The design of locking elements makes it possible to easily remove the cantilever arm from the cable duct, or to provide different positions by which it is possible to change the length of the cantilever arm by positioning it further or further inside the cable duct.

[0028] Another fastening method involves securing tabs on the outside of the side walls, which interact with a cover plate of the cable duct. This method has also proven particularly effective in practice, especially as it allows for relatively easy access. For this purpose, the side walls of the cantilever arm can be moved towards each other, and the cantilever arm inserted into the desired position.

[0029] According to a preferred embodiment, the cantilever arm can further incorporate a strain relief. It has proven particularly advantageous to arrange the strain relief in the area of ​​the fastening section. The strain relief allows for a particularly secure hold and guidance of the cables, while simultaneously improving the distribution of forces.

[0030] A preferred embodiment may provide that the traction element has two clamping levels arranged one above the other. This allows the cables to be sorted easily directly in the area of ​​the traction element.

[0031] Preferably, positioning means can be formed on the inner sides of the side walls and / or the side surfaces of the central web, which interact with complementary positioning means at the strain relief. Such positioning means facilitate the arrangement and fixing of the strain relief elements after the cables have been inserted.

[0032] According to another preferred embodiment, the cantilever arm can have a substantially rectangular shape. The cantilever arm thus adapts to the shape of the cable duct and ensures a clean overall design of the cable management system that integrates well into everyday office life.

[0033] According to a preferred embodiment, the cantilever arm can have an additional downward-extending cantilever arm in the area of ​​the second guide section.

[0034] In summary, the present invention relates to a cable deflection device arranged on a table, guiding cables from a horizontal to a vertical direction. This device features at least one guide section that directs the cables from a horizontal direction into a vertically connected cable guide chain. Preferably, a horizontal and / or a vertical guide section is arranged at the ends of the deflection section. A cable guide chain is arranged on the deflection section or at the end of the vertical guide section. In a preferred embodiment, the deflection section thus connects the horizontal and vertical guide sections.

[0035] Preferably, at least one cable guide chain is arranged on the vertical guide section. A first cable guide chain can be connected in a first vertical direction. It is also possible to arrange the cable guide chain rotated by 90° compared to the first embodiment. Furthermore, several first and second cable guide chains can also be connected to the vertical guide section.

[0036] If several cable guide chains with the same orientation are arranged one behind the other on the deflection device, at least one additional guide section is preferably provided on the deflection device. Each cable guide chain can either have its own guide section, or the cables of a single cable guide chain can be distributed across several guide sections. Distribution across multiple guide sections is advantageous because the cable forces are then reduced accordingly due to the rigidity of the cables. This reduction of bending forces is achieved by targeted cable routing such that the cable is guided completely along a desired bending radius from the horizontal to the desired vertical position within the cable guide chain. Preferably, these guide sections or vertical sections terminate above and at a predetermined distance from the chain link connected to the deflection device.At least one second guide section or vertical section also advantageously terminates here in the middle of a cable chain. This allows cables from a cable guide chain with two chambers to be guided from the vertical direction to the horizontal direction under a desired bending radius.

[0037] Guide and / or deflection sections are preferably designed with at least one, and more preferably two, bands that prevent cables from falling off the sections. The bands are preferably formed by the side walls of the deflection device. If two bands are provided, the second band can be designed as a central web or retaining section. The bands are preferably designed with an increasing or decreasing height to facilitate easy insertion and optimal retention of cables into the deflection device. The minimum distance between the guide sections, or between the guide sections and the bands, the central web, or the retaining section, is preferably at least the thickness of the thickest cable to be guided, to allow for easy cable insertion.

[0038] If the guide sections and / or the areas adjacent to a slot or slot-shaped opening are elastically designed, the gap can also be smaller than the thickest cable to be guided, since these components can be deformed away from each other to insert the cables.

[0039] The deflection device is preferably designed as a substantially rectangular shape in plan view, thus forming a frame. A slot for inserting the cables is provided on one end face of the frame, preferably the end face closer to the table leg. This slot preferably has a width no greater than the thickness of the thinnest cable to be guided, so that the cable cannot slip out.

[0040] The deflection device is preferably located under a tabletop and can preferably be attached to the tabletop, table leg, or cable duct using fasteners. Attachment to the cable duct is preferably achieved using snap hooks and corresponding receptacles. Attachment to the cable duct can be at the end or along its length. Along its length, the deflection device can be connected to the floor from below or above – preferably by clipping it on.

[0041] If the connection is made at the end face, the end face of the cable duct is preferably slotted or U-shaped so that the cables can be inserted from above into the deflecting device, which is preferably open at the top. If the deflecting device is preferably open at the top on at least one side, cables can be inserted and do not need to be threaded through the device. Therefore, the size of the connectors on the cables is irrelevant, as they do not need to be threaded through the device, an opening in another device, or the cable duct itself.

[0042] The cable guide chains are preferably connected to the deflection device such that the slots or the open side of the cable guide chain point towards the end slot of the deflection device. Furthermore, the slots can also point towards the opening and / or gap of the cable duct that runs across the entire deflection device.

[0043] The fasteners for attaching the deflection device can be, for example, screws, clips, hook-and-loop or adhesive systems, or magnetic fasteners / magnets. The fasteners are preferably integrated directly into the deflection device. Snap hooks that engage in corresponding receptacles are particularly preferred. Preferably, the snap hooks are integrated as an extension of the side walls, allowing for easy assembly by pressing the side walls together to engage or disengage the hooks. If a cable strain relief device is installed between the side walls, it prevents the side walls from being moved together by pressing. This ensures that the snap hooks are disengaged when strain relief elements are installed.

[0044] The material of the deflection device is preferably elastic.

[0045] An embodiment of the invention will be explained in more detail below with reference to a drawing. The drawing shows: Fig. 1 a cantilever arm according to one embodiment, in a three-dimensional view obliquely from above, Fig. 2 the in Fig. 2 cantilever arms shown in a top view, Fig. 3 the in the Fig. 1 and Fig. 2 cantilever arms shown in a sectional view along line CC in Fig. 2, Fig. 4 the in the Fig. 1-3 cantilever arm shown with energy supply chains arranged on it, and Fig. 5 the cantilever arm according to the invention with an energy supply chain arranged transversely to the longitudinal direction and with a view to the fastening section.

[0046] The deflection device according to the invention is described below using a cantilever arm as an example. However, the features described below with regard to the cantilever arm can also be implemented in any other deflection device. The deflection device according to the invention can also be implemented in other ways, as long as it has a substantially horizontal guide section and at least one deflection section adjoining it for deflection into at least one vertical guide section facing the energy chain.

[0047] In Fig. Figure 1 shows a cantilever arm in a top-down view, allowing a view into the cantilever arm. It is evident that the cantilever arm as a whole has a very angular, clean shape, thus continuing the form of the cable duct.

[0048] The cantilever arm 1 guides the cables arranged in the cable duct horizontally and then deflects them vertically. When many different cables are routed in a cable duct, especially in networked desks, proper cable organization is essential. The cantilever arm 1 according to the invention provides a system that allows the cables to be bundled and arranged in a structured manner directly at the transition point of the cantilever arm 1.

[0049] Specifically, the cantilever arm 1 comprises a mounting section 2, which is attached to or within the cable duct. A first guide section 3 adjoins the mounting section 2, in which the cables are guided essentially horizontally. Following the guide section 3, on the side facing away from the cable duct, is a conversion section 4, in which the cables exiting the cable duct are transferred from a horizontal direction into a vertical guide section 5.

[0050] Regarding the vertical guide section 5, it should be noted that this can also be formed only in the connection area of ​​an energy chain. The distinction between the conversion section 4 and the vertical guide section 5 is fluid and cannot always be clearly assigned to one section or the other.

[0051] In general, the cantilever section 25, arranged on the cantilever arm 1 and extending downwards on the side facing away from the fastening section 2, can be referred to as the second guide section 5. The fastening and connection means for the energy chains are also located in this area.

[0052] The cantilever arm 1 is essentially channel-shaped, with a crossbar 6 forming the base, to which side walls 7, 8 are attached on both sides. The length of the side walls 7, 8 determines the overall length of the cantilever arm 1 and extends beyond the crossbar 6. The crossbar 6 is only present in the area of ​​the fastening section 2 and the guide section 3. On the side facing away from the cable duct, the side walls 7, 8 are connected to each other by an end wall 9, which can also be formed as two opposing side wall sections separated by a slot 10. A corresponding slot 10 can also be provided in the area of ​​one of the two side walls 7, 8 in the area of ​​the conversion section 4.

[0053] The guide section 3 is divided into two chambers 12, 13 by a central web 11, allowing the cables to be routed separately within the chambers. The central web 11 extends into the mounting section 2, but not to its end. Furthermore, the central web 11 extends beyond the first guide section 3 into the second vertical guide section 5, or rather to the end of the second vertical guide section 5. The central web 11 is lower than the side walls 7, 8, so that the outer structure of the cantilever arm 1 is determined by the shape of the side walls 7, 8.

[0054] However, the central web 11 can have any desired height, and the height can vary along the length of the central web 11, rising or falling.

[0055] From the sectional view in the longitudinal direction of the cantilever arm 1, according to Fig. Figure 2 shows that the crossbar 6 is initially arranged essentially horizontally and then rises slightly upwards to the end of the first guide section 3. This defines the cable routing without stressing the cables.

[0056] Between the guide section 3 and the conversion section 4, two opposing retaining webs 14 are formed at the upper edge of the side walls 7, 8, aligned with each other and forming a slot 15. These retaining webs 14 ensure that the cables are held in the cantilever arm 1. In the area below these retaining webs 14, the crossbar 6 can be formed with openings, creating through-openings 16 in the area of ​​the crossbar 6. These through-openings 16 define the transition between the guide section 3 and the conversion section 4. The through-openings arranged below the retaining webs 14 can also be created by manufacturing in an "open / close" tool and not only facilitate manufacturing but also have a positive effect on manufacturing costs.

[0057] In the area of ​​conversion section 4, the cables are deflected from a substantially vertical to a substantially horizontal direction, with the deflection taking place in two successive deflection sections 17, 18. The first deflection section 17 is, as is particularly clear in the sectional view in Fig. Figure 2 shows the crossbar 6 extending from the crossbar. The first deflection section initially has a bend and then transitions into a vertical section 19. The bend or curve is chosen such that the minimum bending radius of the cables is not undercut. The bend only occurs over a predetermined area, and the entire rise of the crossbar 6 in the area of ​​the guide section 3 is not compensated for by the bend. This means that the bend made by the crossbar 6 ends above the horizontal section of the crossbar 6.

[0058] As seen especially in the section view in Fig. As shown in Figure 3, the crossbar 6 performs an almost wave-like movement in the longitudinal direction of the cantilever arm 1.

[0059] The first deflection section 17 is also divided into two chambers by the central web 11. This creates two opening areas where the slot width must preferably be smaller than the diameter of the smallest cable to be guided. These openings are, on the one hand, the slot 15 between the two retaining webs 14 and, on the other hand, the slot-shaped opening between each retaining web 14 and the central web 11.

[0060] Parallel to the first deflection section 17, the second deflection section 18 is arranged. Unlike the first deflection section 17, the second deflection section 18 does not extend between the two side walls 7, 8, but is formed in the form of two curved support sections 20, each arranged on one of the side walls 7, 8 and separated from each other by a slot-shaped opening 22. The slot-shaped opening 22 ensures that the cables can be inserted through the slot 10 in the end wall 9 in such a way that they are also positioned in the area of ​​the first deflection section 17.

[0061] Each support section 20 is bounded at its edge furthest from the side wall 7, 8 by a retaining section 21, which extends upwards parallel to the side wall 7, 8. These retaining sections 21 also ensure that the cables are guided within the area of ​​the support sections 20.

[0062] By combining the two successively arranged deflection sections 17, 18 with the chambers formed by the central web 11 and the retaining sections 21, it is possible to guide the cables selectively, section by section, side by side, then one above the other, and finally one behind the other. The minimum bending radius of the cables is not undercut in this process.

[0063] On the lower side of the cantilever arm 1 and in the area of ​​the vertical guide section 5, fastening elements 23 for two energy guide chains 24 are arranged in the area of ​​each chamber of the first deflection section 17 and on the opposite end wall 9, which can be arranged parallel to each other and in the longitudinal direction of the cantilever arm 1. Fig. Figure 4 shows a corresponding embodiment.

[0064] Furthermore, corresponding fastening elements 23 are also found in the area of ​​the side walls 7, 8, so that two energy chains 24 can likewise be arranged parallel to each other transversely to the longitudinal direction of the cable duct. A cantilever arm 1 with only one energy chain 24 arranged transversely to the longitudinal direction is in Fig. Figure 5 shows the fastening elements. The fastening elements shown are only examples and can be replaced by any known fastening element 23. Only one joint half is mentioned here as an example, which can be coupled to a complementary joint half in the area of ​​the energy chain.

[0065] Depending on requirements, one or two energy chains can be arranged on the cantilever arm 1 in the desired direction. The cantilever arm 1 according to the invention thus provides a very flexible system that makes it possible to thread new cables, energy chains, and cable ducts into the cantilever arm 1 at any time without much effort.

[0066] With regard to two energy chains arranged longitudinally along the cantilever arm 1, it has proven particularly advantageous if the slots in the area of ​​the individual chain links, for inserting the cables into the energy chain, are arranged opposite each other, so that the cables can be inserted equally into the slots in the area of ​​the energy chain 24 and into the slot 10 in the area of ​​the end wall 9 of the cantilever arm 1. This clearly provides a very flexible cable management system. Even if the cantilever arm 1 and the energy chain are already mounted, it is easily possible to insert a cable into a specific desired area at a later stage.

[0067] The cantilever arm 1 is connected to the cable duct in the area of ​​the fastening section. For example, the cantilever arm 1 can be connected to a base 27 of the cable duct via fixing elements 26, as shown in Fig. Figure 5 shows the fixing elements 26 on the underside of the crossbar 6. The fixing elements 26 can be of any design, as long as a secure connection to the base 27 of the cable duct is ensured. For example, the fixing elements 26 can be inserted into receiving openings 28 in the area of ​​the base 27. For this purpose, the fixing elements 26 can be designed as slotted mushroom heads that are compressed when inserted into the receiving openings and then expand to rest against the underside of the cable duct base 27.

[0068] At the in Fig. The embodiment shown in Figure 5 is a fastening system that allows for longitudinally variable fastening, so that the section of the cantilever arm 1 protruding from the cable duct can be changed.

[0069] For this purpose, the fixing elements on the underside of the crossbar 6 in the fastening section 2 are designed as locking projections that can be pressed into elongated openings in the area of ​​the cable duct base 27. If the position of the cantilever arm 1 is to be changed, these locking projections can be moved towards or away from each other to be removed from the receiving openings 28. They are then inserted into the desired new receiving opening. In this embodiment, the cable duct base 27 is provided with a plurality of elongated receiving openings 28 arranged one behind the other and parallel to each other.

[0070] The cantilever arm 1 can also be designed with a fastening element in the area of ​​the side wall, for example, to be glued into an opening of a cover of the cable duct. In this embodiment, which is not shown, two retaining webs or sections extending vertically on the outside, parallel to each other, can be arranged on both side walls 7, 8 in the area of ​​the fastening section 2. When the cantilever arm 1 is inserted into the opening of the cover, the cover can be held between these two retaining webs. In this embodiment, it has also proven advantageous to have a step on the underside of the cross web, which simultaneously defines the stop of the cover, thus significantly facilitating the insertion of the cantilever arm 1.

[0071] To insert a suitably shaped cantilever arm 1 into the opening of the aperture, the rear end sections of the cantilever arm 1 can, for example, be pressed together. Since the cantilever arm 1 is made of a base material, the material allows a certain degree of flexibility and thus significantly facilitates the installation of the cantilever arm 1.

[0072] The cantilever arm 1 also has strain reliefs 29 in the area of ​​the fastening section 2, which are arranged at a predetermined distance to an end edge 30 of the cantilever arm 1.

[0073] Specifically, each chamber 12, 13 is equipped with a strain relief 29, which are separated from each other by the central web 11. The height of the central web 11 in the area of ​​the strain relief 29 corresponds to the height of the strain reliefs 29.

[0074] The strain relief 29 allows the cables to be clamped or fixed on two horizontally arranged planes. In the first plane, the cables are positioned between the crossbar 6 and the first half 31 of the strain relief. Both the crossbar 6 and the first half 31 are provided with rounded recesses in this area, which allow the cables to be clamped. The first half 31 of the strain relief is provided with corresponding rounded recesses not only on its underside but also on its upper side, so that cables can also be clamped between the first half 31 and a second half 32 to which it can be connected.

[0075] The strain relief halves 31, 32 can be easily fixed together by means of screws which are screwed into openings 33 and interact with a screw-in area 34 in the area of ​​the cross web 6.

[0076] To facilitate the arrangement of the strain relief 29, both side walls 7, 8 and the central web 11 are provided with positioning ribs 35, 36 on their inner sides, extending vertically from an upper edge to the cross web 6. These positioning ribs 35, 36 interact with grooves on the sides of the strain relief halves 31, 32 and act as guide rails during insertion.

[0077] It is noted that the sections of the cantilever arm between which the cables can be inserted and removed, for example slots or slot-shaped openings, are preferably designed to be elastic or to have a certain degree of elasticity in order to facilitate insertion.

[0078] According to a further embodiment, the present invention relates to a deflection device for a table cabling system for transferring several cables from the horizontal into a vertically arranged cable guide chain with a deflection section for deflecting the cables in a vertical direction in the first chain link of the cable guide chain.

[0079] The deflection section can be designed with a substantially horizontal guide section and / or a vertical guide section.

[0080] Furthermore, it has proven advantageous if the transverse axis of the cable guide chain is arranged parallel to the longitudinal axis of the deflection section.

[0081] The transverse axis of the cable guide chain can be arranged rotated by 90° to the longitudinal axis of the deflection section.

[0082] Furthermore, multiple cable guide chains can be connected.

[0083] Similarly, multiple deflection sections can be formed.

[0084] The deflection sections can be designed so that they only partially protrude into the interior of the deflection device, in such a way that the thickest cable to be routed can fit through between them.

[0085] At least one side of the deflection sections, barriers may be provided.

[0086] The barriers can be formed by side walls.

[0087] If side walls are provided, they can essentially form a frame. The resulting frame can be essentially rectangular. Furthermore, the frame can be open on one side, this opening preferably being a slot through which the cables can be inserted. The frame and / or slot can be closed with a cover.

[0088] Furthermore, the deflection device may be designed to be openly accessible from one side. This accessible side may be the top, bottom, or a side wall of the deflection device.

[0089] Preferably, the deflection device is fixed under the table. This fixing is achieved using fasteners such as clips, screws, hook-and-loop systems, straps, or adhesive systems. The fasteners are designed as locking tabs with corresponding receptacles. These receptacles are either elongated slots or keyhole-shaped holes.

[0090] The strain relief can be designed in such a way that, in the installed state, the side walls of the deflection device, for example the cantilever arm or the frame, can no longer be squeezed together by hand.

[0091] The guide and deflection sections can be designed in such a way that it is possible to switch from one to the other while maintaining desired bending radii.

[0092] The band also serves, or preferably serves, for stiffening.

[0093] One or more covers may be provided.

[0094] A predominantly rectangular shape is also preferred in the side view.

[0095] The cables of the first guide section are led into the second guide section and can lie on top of the cables of the second guide section.

[0096] The bending radii of the guide sections can sometimes be slightly less than the permissible cable bending radii if a protrusion is present, for example, due to the connection of a cable guide chain.

[0097] The features described above can be combined in any combination in a deflection device.

[0098] Further aspects are listed below: 1. Deflection device for a table cabling system for transferring several cables from the horizontal into a vertically arranged energy chain or cable guide chain, with at least one deflection section for deflecting the cables in a vertical direction in the first chain link of the energy chain or cable guide chain. 2.
