Description

[0001] The present invention relates to a cable guidance and laying aid device according to the preamble of claim 1.

[0002] Various guiding and laying aids are already known for laying cables, especially electrical or fiber optic data cables. These devices serve the purpose of protecting both the surfaces and sheathing of the cables being laid, as well as surfaces against which the cables would otherwise rub during installation. For example, but not exclusively, such devices are used when cables, cable strands, or bundles of cables are to be laid or inserted into a pre-assembled cable duct.This is because, both during the cable entry into the cable duct and when bending the cable duct, there is a problem or risk that, without appropriate aids, the cables to be laid will reach the edges of the cable duct and have to slide or slide along these edges, which in turn can have detrimental effects on the cables, especially on the cable sheathing or cable surface. Furthermore, when routing cables through wall penetrations, door openings, or similar openings, a suitable minimum distance from the walls, for example, from the door frame, can be ensured to protect the cables by using appropriate guides and routing aids, so that the cables do not have to slide along the walls or the door frame.

[0003] A well-known cable pulling or cable laying aid of this type is offered and distributed by the company "Cimco International". Rollers with a curved surface are arranged relative to each other in a frame such that sections of the roller surfaces form a guide opening or a feed-through opening. The frame, which ensures the attachment and relative positioning of the rollers, can itself be attached to a cable duct or the like by means of screw holders that can be detachably fastened to the frame and, in the attached state, used for routing the cables to be laid.

[0004] A disadvantage of the devices of this type from the prior art is their relatively complex and difficult assembly at the place of use.

[0005] From DE 10 2020 106 097 B3 of the applicant, a cable guidance and laying aid device with a lever actuation device is known which is movable along an adjustment direction in order to enable a clamping fastening of the cable guidance and laying aid device to a flat, protruding object or object section by moving a guide unit and a fixing unit towards each other.

[0006] Based on this prior art, the object of the present invention is to propose a cable guidance and laying aid device that addresses the disadvantages in the prior art in order to ensure, in particular, quick and easy assembly or fastening.

[0007] This problem is solved with a device having the features of claim 1. Advantageous embodiments of the cable guidance and laying aid device according to the invention are the subject of the following description and description of figures, as well as the dependent claims.

[0008] The aforementioned problem is solved by a cable guidance and laying aid device comprising a fixing unit and a guide element connected to the fixing unit for arrangement on a first surface, which has a feed-through opening whose inner circumferential surface, preferably at least partially, is limited by guide rollers rotatably mounted on the guide element, and wherein the guide element is designed to be movable relative to the fixing unit along an adjustment direction, and comprising a clamping unit which is connected to the fixing unit for clamping with a second surface.

[0009] According to the invention, it is provided that the through-opening, preferably open on one side, is formed adjacent to a base surface on the bottom, preferably at least partially flat, and that the guide element is arranged in such a way that it is movable in a clamped state of the clamping unit.

[0010] For the sake of linguistic simplification, the term "cable guidance device" will be used below instead of the term "cable guidance and laying aid device", this is done solely for reasons of readability of the overall disclosure.

[0011] The device according to the invention is based on the fundamental idea of ​​providing a partially movable, but essentially one-piece device that includes both the means required to provide the feed-through opening and, at the same time, provides or supplies the means required to attach the device, for example, to a cable duct. The invention recognizes that the second surface on which the cable guide device is positioned can be used to form a clamping mechanism that pre-fixes the cable guide device in its position.Since the guide element remains movable in this clamped state, its position can still be adjusted to the existing installation situation. Furthermore, the arrangement of the guide element on the first surface further stabilizes the final configuration of the cable management device. This significantly simplifies the installation of the cable management device, as the clamping step, which requires a certain amount of force to ensure stability and would have to be applied again if the position were to be corrected, does not yet permanently fix the guide element, which ultimately guides the cables. Therefore, adjustments remain possible.

[0012] The feed-through opening is advantageously designed to accommodate one or more cables, and is preferably located on the lower side of the guide element, particularly open on one side. This allows the cable guide to be advantageously placed and / or slid over the cables running in a cable tunnel, with the feed-through opening being bounded at its advantageously open side by the first surface on which the cable guide is arranged. Alternatively, it is also conceivable that the feed-through opening is closed by a bridge, which advantageously includes a closing and opening mechanism. The base is advantageously at least partially flat, and it is also possible that the base is formed by feet, which can be height-adjustable, for example, to adapt to a non-flat surface.

[0013] In the following, the fixing unit and the clamping unit are defined as belonging to the upper part of the cable management device, and the direction leading towards and / or beyond the top of the fixing unit and / or clamping unit is understood as an upward direction. The guide element is defined as belonging to the lower part of the cable management device, and accordingly, the direction leading towards and / or beyond the base of the guide element is understood as a downward direction. This does not necessarily mean that the guide element is arranged at a lower height than the fixing unit; for example, it is also conceivable that the cable management device is arranged horizontally above or below an opening in a first surface.

[0014] According to a first advantageous embodiment, the fixing unit can be designed such that increasing the distance between the guide element and the fixing unit along the adjustment direction allows the guide element to be clamped between two surfaces, in particular a first surface resting on the base and a second surface resting on the clamping unit. This is achieved by providing the guide element with a base that can be positioned on a first surface, for example, the bottom of a cable duct or cables already laid in the cable duct, wherein the clamping unit can be arranged and / or clamped at least partially on and / or under a second surface, in particular on the side wall of a cable tunnel or on a wall penetration.When the distance between the guide element and the fixing unit is increased, the clamping unit is pressed against the second surface, creating a preload along the adjustment direction. This preload presses the guide element, which is preferably frictionally connected to the fixing unit, against the first surface with its base. This preload thus securely clamps the cable guide in its position, preventing lateral tilting and the associated release of the clamp.

[0015] According to a further advantageous embodiment, the clamping unit can comprise a clamping element with at least one first force application surface, preferably extending substantially perpendicular to the adjustment direction, for clamping contact with the second surface, preferably a wall of an underfloor box. This embodiment is particularly preferred for clamping the unit stably to the second surface perpendicular to the adjustment direction and thus preventing lateral tilting or loosening of the cable management device. The first force application surface can be variably designed, with a larger first force application surface achieving more stable positioning.The clamping unit can be rigidly connected to the fixing unit, particularly as part of or an extension of the fixing unit. It is especially preferred to design the clamping unit as an independent unit, preferably movably connected to the fixing unit. Designing it as an independent unit allows for greater flexibility in its configuration.

[0016] According to a further advantageous embodiment, the clamping element can be designed to be movable relative to a locking unit of the clamping unit along the adjustment direction. This allows the clamping element to be arranged on a second surface particularly easily, and especially without any tension, and the clamping can only be achieved in the final position of the clamping element. Furthermore, the position, especially the height, of the clamping element can be adapted to the mounting situation.

[0017] According to a further advantageous embodiment, the guide element can be connected to at least one first adjustment rail, preferably rotationally movable, wherein the first adjustment rail is mounted on, preferably at least partially within, the fixing unit and is movably mounted relative to the fixing unit along the adjustment direction. Overall, this arrangement makes it possible to move the guide element and the fixing unit relative to each other along the extent of the first adjustment rail and to provide a force-fit connection between the fixing unit and the guide element, whereby a more linear force transmission can be achieved via the first adjustment rail than with a direct, for example offset, connection between the fixing unit and the guide element.

[0018] The first adjustment rail is preferably routed through the fixing unit along the adjustment direction and is particularly delimited at its upper side, above the fixing unit, by an attachment element or an end piece, which can be monolithic or designed as an additional part. At its lower end, the first adjustment rail is connected to the guide element, the connection preferably being designed with a pivot joint that allows the guide element to rotate about the axis of the first adjustment rail. A cylindrical mandrel is particularly preferably formed on the first adjustment rail, which in particular has circumferential bores as detent positions. A bushing complementary to the mandrel is formed on the guide element, in which the mandrel is received. The bushing in particular has pressure balls, which are preferably spring-mounted, which engage in the bores in preferred positions, preferably every 45°.A ring ridge is advantageously formed on the mandrel, which axially secures the mandrel in the bushing. It is also possible to arrange the mandrel on the guide element and the bushing on the first adjustment rail. The swivel joint advantageously allows for a more flexible arrangement of the guide element on the first surface. As a further development, it can be advantageously provided that the connection between the fixing element and the first adjustment rail is detachable, particularly with tools, thereby allowing guide elements with different embodiments, for example, with a through-hole, to be connected to the first adjustment rail depending on the assembly situation.

[0019] Alternatively, it can be advantageously provided that the fixing unit is movably mounted on at least two first adjustment rails, such that the fixing unit is adjustable, and in particular displaceable, along the adjustment direction, wherein the first adjustment rails are arranged on, preferably at least partially within, the guide element. This advantageously results in a single-piece cable guide device in which the first adjustment rails, on the one hand, enable the adjustment of the fixing unit relative to the guide element or vice versa, and, in a preferred embodiment, simultaneously provide the connection between the fixing unit and the guide element. This allows for a compact and equally simple design.The first adjustment rails are preferably routed through the fixing unit along the adjustment direction and are particularly delimited at their upper end, above the fixing unit, by end pieces, preferably end nuts. At their lower end, the first adjustment rails are advantageously arranged in the guide element, resulting in a particularly preferred arrangement which allows the fixing unit to be moved between the guide element and the end pieces along the first adjustment rails in the adjustment direction and provides a force-fit connection between the fixing unit and the guide element.

[0020] According to a further advantageous embodiment, the clamping element can be connected to a second adjustment rail, wherein the second adjustment rail is movably mounted on, preferably at least partially within, the locking unit and relative to the locking unit along the adjustment direction. This allows the clamping element to be movably positioned relative to the clamping unit, which is particularly advantageous, thus facilitating the positioning of the clamping element on the second surface. The second adjustment rail is preferably arranged completely within the locking unit along the adjustment direction and its movement along the adjustment direction is limited, particularly at its upper side, by a limiting element formed on the second adjustment rail, preferably a pin which is guided in a guide tab of the clamping unit.At its lower end, the second adjustment rail is connected to the clamping element.

[0021] According to a further advantageous embodiment, the adjustment direction of the clamping element can be provided that does not correspond to the adjustment direction of the guide unit, i.e., that the clamping element is movable along a second adjustment direction, which differs from the first adjustment direction. This can be achieved, for example, by arranging the first and second adjustment rails not parallel, but at an angle of 1 to 179° to each other, and has the advantage that the cable guide device can be designed more flexibly for different mounting situations.

[0022] According to a further advantageous embodiment, the locking unit can be provided with a second force application surface, which is designed to be complementary to the first force application surface, in particular with an orientation opposite to the adjustment direction of the first force application surface. This advantageously allows for contact on both sides with the second surface, making the cable guide particularly stable and supporting it against lateral tilting. In the embodiment with a movable clamping element, the second force application surface can also be used as a positioning aid by first placing the second force application surface against the second surface and then, by moving the clamping element towards the locking unit, achieving contact and clamping on both sides.

[0023] According to a further advantageous embodiment, the clamping element can be designed as one or more clamping hooks, each comprising a, in particular elastically resilient, stretched section, wherein the first force application surface is formed, in particular at least approximately perpendicularly, on and / or adjacent to the stretched section. This allows the clamping element to be arranged on a second surface particularly intuitively and easily, wherein the stretched section is advantageously designed to be at least slightly resilient, at least approximately perpendicular to the adjustment direction, which on the one hand reduces the material stress caused by clamping with a second surface and on the other hand allows the clamping element to be positioned particularly easily against the second surface. The clamping hooks are advantageously designed such that they form an overall shape at least approximately S-shape.In this embodiment, the clamping unit and the clamping element are advantageously fixed relative to the fixing unit and preferably designed as an attachment to the fixing unit. The fixed clamping element also eliminates the need for a fixing mechanism, which is why the clamping unit in this embodiment does not include a locking unit.

[0024] Further development may provide that the clamping element comprises at least one, preferably two, upper clamping hooks and at least one lower clamping hook, wherein the lower clamping hook and the upper clamping hook(s) are configured with opposite orientations along the adjustment direction, preferably in a pincer-like manner. Advantageously, the upper and lower clamping hooks have a common origin plane on the fixing unit or clamping unit, from which they extend in opposite directions. Further preferred, the upper clamping hooks are arranged laterally to the left and right of the lower clamping hook on the origin plane, thereby creating, in particular, an alternating arrangement between the upper and lower clamping hooks.This design advantageously improves the stability of the clamped cable guide device even further, especially perpendicular to the adjustment direction, and increases the possible receiving area of ​​a second surface or object.

[0025] Further development may involve designing the extension section and / or the first force application surface of the lower clamping hook with a greater width and / or length than the extension sections and / or the first force application surfaces of the upper clamping hook(s). Advantageously, the width of the lower clamping hook can be approximately as large as the combined width of the upper clamping hooks. This particularly benefits the first force application surface of the lower clamping hook, resulting in a particularly stable clamp. The advantageously greater length also improves the elasticity of the lower clamping hook, thereby facilitating positioning and reducing material stress.

[0026] According to a further advantageous embodiment, the clamping element, in particular the first force application surface, can be provided with at least one rubber coating. This is advantageous in order to protect both the cable guide device and the second surface to which it is clamped from damage. Furthermore, the rubber coating creates static friction and a propagation pressure between the first force application surface and the second surface, thereby further increasing the stability perpendicular to the direction of adjustment.

[0027] According to a further advantageous embodiment, the fixing unit may include a first locking device configured to secure the guide element and / or the first adjustment rail against movement relative to the fixing unit, in particular to block only a reduction in the distance between the fixing unit and the guide element in the adjustment direction. This advantageously allows the position, preferably the preload state, of the cable guide to be determined by preventing the pressure exerted on the guide element by the first surface from causing a compensating movement of the fixing unit and / or the guide element, and / or by preventing the fixing unit from sinking in the direction of the guide element. Advantageously, two first locking devices may be configured, particularly in a mirror-symmetric configuration, or as many first locking devices as there are first adjustment rails.The first locking device is particularly advantageous because it prevents a reduction in the distance and allows an increase in the distance between the guide element and the fixing unit. This makes it especially easy for the user to attach the cable guide device, since movement in the fastening direction is always possible, but the opposite release movement is blocked.

[0028] According to a further advantageous embodiment, the locking unit may include a second locking device designed to secure the clamping element and / or the second adjustment rail against movement relative to the locking unit, in particular to block only an increase in the distance between the locking unit and the clamping element in the adjustment direction. This allows the clamping position of the clamping element, and thus the pre-fixed state of the cable guide device, to be determined if the clamping element is movable relative to the locking unit, by preventing the pressure exerted on the clamping element and / or the locking device by the second surface from causing a compensating movement of the clamping element or the locking unit.The locking device preferably blocks any increase in the distance and allows a decrease in the distance between the locking device and the clamping element. This makes it particularly easy for the user to clamp the cable guide device, as movement in the clamping direction is always possible, but the opposite release movement is blocked.

[0029] According to a further advantageous embodiment, it can be provided that the first and / or second locking device can assume an open state and a locked state, wherein the first and / or second locking device comprises at least one locking element, preferably a clamping plate, which has a recess for receiving and / or passing through the first and / or second adjusting rail, wherein the first and / or second adjusting rail is clamped by the locking element in the locked state.The first and / or second locking device can each assume an open state and a locked state, each comprising a locking element with a recess. The first locking device has a recess for receiving and / or guiding the first adjustment rail, while the second locking device has a recess for receiving and / or guiding the second adjustment rail. In the locked state, the respective adjustment rail is clamped by the respective locking element. In its locked state, the locking device can hold the fixing unit and / or the clamping element and / or the locking unit and / or the clamping element on the adjustment rails in their position, preferably pre-tensioned and / or clamped. The open state releases the pre-tensioned and / or clamped position, thereby enabling the cable guide device to be fully reused.The blocking element is preferably designed as a clamping plate or as a stack of clamping plates connected by friction, although other designs, for example as clamping bolts, are also conceivable.

[0030] According to a further advantageous embodiment, the locking element can be movably mounted on bearing means, in particular rotationally movable, preferably in a lever-like manner, wherein in the locked state an outer end of the locking element is arranged lowered relative to an inner end, thereby forming at least two clamping surfaces between the locking element, in particular on the inner circumference of the recess, and the first and / or second adjusting rail guided through the recess. This design has also proven to be particularly robust and stable over a large number of cycles between the open and locked states.By lowering the inner end of the locking device or raising the outer end, preferably until the locking device is arranged approximately horizontally, the clamping surfaces are released and the first and / or second locking device is moved into its open state, in which the fixing unit and / or the locking unit can move along the adjustment direction on the first and / or second adjustment rail.

[0031] According to a further advantageous embodiment, the outer end can be designed in a fork-like form, wherein the fixing unit comprises an edge element in and / or on which the outer end is arranged to engage, forming a pivot point for the locking element. With this embodiment, a lever-like mounting of the locking element can be achieved particularly advantageously, and the fork-like end and the edge element can be manufactured and assembled particularly easily using established processes.

[0032] According to a further advantageous embodiment, the locking element can be mounted so as to be rotatable about its outer or inner end. Mounting it about the inner end blocks downward movement, which is why this mounting is preferred for the second locking device to prevent an increase in the distance between the clamping element and the locking unit, although a reduction is possible. This allows the clamping, and advantageous preload, to be increased in the locked state, but not relaxed. Mounting it about the outer end blocks upward movement, which is why this embodiment is preferred for the first locking device to prevent a reduction in the distance between the locking unit and the guide element, although an increase in the distance remains possible.

[0033] This makes it possible to increase the advantageous preload in the locked state, but not to relax it.

[0034] According to a further advantageous embodiment, the first and / or second locking device may include a release device which is designed as a lever-like extension of the locking element and projects out of a housing or the respective housings of the fixing unit and / or locking unit, wherein by a movement of the release device the respective outer end is raised or the inner end is lowered, in particular until the locking element is arranged at least approximately perpendicular to the first and / or second adjusting rail.

[0035] Alternatively, the first and / or second locking device may include a release mechanism comprising a push button, which is movable along the adjustment direction relative to the fixing unit. The release mechanism includes a driver, in particular a circumferential bead, which, when the release mechanism is moved downwards, presses against the inner end of the locking unit, thereby lowering the inner end, in particular until the locking element is at least approximately horizontal or at least approximately perpendicular to the first and / or second adjustment rail. In this context, "circumferential" does not necessarily mean that the release mechanism must be round and / or cylindrical; for example, in addition to a round design, an arbitrarily polygonal design, in particular a rectangular one, is also conceivable.Advantageously, the fork connection described above prevents the outer end from lifting. A push button or lever design is advantageous because it allows for intuitive use; it is also conceivable to design one release mechanism as a lever and the other as a push button. The release mechanism can preferably have a surface texture, such as knurling, gripping studs, or roughness, which improves grip, and / or markings, where the markings can advantageously be three-dimensional to further improve grip.

[0036] According to a further advantageous embodiment, a first spring element can be assigned to each of the first and / or second locking devices, which applies force to the first and / or second locking device and / or the respective locking element, thus compelling it into its locked position. This ensures that the first and / or second locking devices are always in the locked position as their default state, enabling quick and easy assembly of the cable guide device and preventing the locking mechanism from being forgotten during assembly. The first spring element can, for example, be a coil spring.

[0037] According to a further advantageous embodiment, a third spring element can be assigned to each release device, which can be pre-tensioned by moving the release device along the adjustment direction towards the guide element. This embodiment is particularly preferred for use as a push button, since it allows the release device to automatically return to its original state and thus be ready for re-actuation. The third spring element can, for example, be a coil spring.

[0038] According to a further advantageous embodiment, fourth spring elements can be assigned to the bearing elements, wherein the fourth spring elements are pre-tensioned in the open state, particularly when the inner end is lowered. This embodiment works particularly advantageously in conjunction with the third spring elements to allow the locking device to automatically return to the locked position after the fixing unit and / or the guide element has been adjusted in the open state. The fourth spring elements also make it particularly easy to achieve the inclined arrangement of the locking element, and the first and / or second locking devices can be given at least a slight buffering elasticity, which prevents damage caused by over-tensioning of the cable guide device. The fourth spring elements can, for example, be a coil spring.

[0039] According to a further advantageous embodiment, the clamping unit may have a handle arranged on the locking unit, which is connected to a push element in such a way that, when the handle is actuated, the push element displaces a sheet metal arranged in the locking unit, and wherein a second spring element is arranged on the second adjusting rail, which is compressed by the displaced sheet metal in such a way that the restoring force of the second spring element tilts the sheet metal, causing it to clamp onto the second adjusting rail and to move it in the push direction along the adjustment direction.In other words, by operating the handle, the sheet metal is pushed against the second spring element, which is thereby compressed. Its restoring force tilts the sheet metal, which is only pushed upwards on one side by the pushing element, causing it to clamp against the second adjustment rail. This clamping action temporarily connects the second adjustment rail and the sheet metal, transferring the force acting on the sheet metal to the second adjustment rail, where this force is an upward thrust. Thus, by operating the handle, the second adjustment rail can be retracted a certain distance into the locking unit. To bring the extended clamping element into contact with the second surface, the handle can be operated repeatedly until the first force-applying surface makes contact with the second surface and further retraction is no longer possible.After the lever is actuated, the sheet metal is returned to its starting position by the restoring force of the second spring element. The second spring element can be, for example, a coil spring.

[0040] According to a further advantageous embodiment, the fixing unit and the clamping unit can be rotationally connected to each other, in particular via an indexing joint. This allows the cable guide device to be positioned particularly flexibly on the first and second surfaces. The indexing joint comprises, in particular, two indexing discs, a first indexing disc being arranged on the fixing unit and a second indexing disc on the locking unit. The indexing discs have complementary teeth that define the possible positions in which the indexing discs can be arranged relative to each other and thus determine the rotational steps. The indexing discs have a recess, in particular a central one, through which a bolt is guided.The bolt is connected to the locking unit or the fixing unit on one side and closed off on the opposite side, preferably with a round nut and screw, such that the components of the indexing joint arranged between the sides cannot be detached from the bolt. A fifth spring element, for example a coil spring, is also mounted on the bolt, which biases the first indexing disc against the second indexing disc, or vice versa. In the initial state, the teeth of the indexing discs of the indexing joint are interlocked, thus preventing rotation. For the indexing joint to rotate, the indexing discs must be pulled apart to such an extent that the tips of the teeth of the first and second indexing discs can pass each other during a rotating movement.For this purpose, the teeth are advantageously designed with a rounded tip so that they can slide against each other. Pulling them apart tensions the spring element, which, upon completion of the active pulling process, returns the indexing discs to their initial position due to the restoring force of the fifth spring element, allowing the complementary teeth to slide into the toothed arrangement. Advantageously, the spring tension of the fifth spring element is set such that pulling the teeth apart, i.e., overcoming the restoring force of the fifth spring element, is possible manually, but the return to the initial position is nevertheless quick and reliable.

[0041] According to a further advantageous embodiment, the guide element can have several, preferably two, insertion openings on its base, which preferably serve to receive locking pins of, preferably two, feet. Advantageously, the insertion opening and the locking pins have complementary threads, allowing the feet to be screwed into the insertion openings, particularly independently of each other, to a desired depth and thus allowing their height to be adjusted to different surfaces. The internal threads are particularly preferably provided by nuts, for example hexagonal nuts or flange nuts, associated with the insertion opening and / or the locking pin.In this design, the locking pins, preferably cylinder head screws, are initially arranged within the guide element and are screwed downwards, i.e., towards the base, with the nuts, thus forming a portion of the locking pins protruding from the guide housing, on which the feet are attached. The feet preferably have a rubber coating or consist of rubber and / or a rubber-like material, creating static friction between the feet and the surface, which improves the stability of the cable management device. In this embodiment, the feet are to be understood as parts and / or extensions of the base, although it is also conceivable that the feet completely define the base.It is possible, on the one hand, for the feet and other sections of the base to rest against a first surface, or on the other hand, for only the feet to rest against a first surface. In the latter case, the feet can also be positioned at a distance from the other sections of the base, particularly by unscrewing the locking pins.

[0042] According to a further advantageous embodiment, the through-hole can be designed to be at least approximately semicircular. Alternatively, the through-hole can also be arbitrarily polygonal, with the semicircular design being particularly preferred. In a further preferred embodiment, the through-hole can be designed to be approximately circular overall, preferably formed by two guide elements, each with at least approximately semicircular through-holes, which are movably, and in particular pivotably, mounted to one another by a mechanism, preferably a hinge, and reversibly fixed by a locking element.

[0043] According to a further advantageous embodiment, the first and / or second force application surface may have a surface texture, in particular incorporated grooves and / or recesses, and / or the first and / or second force application surface may surround the second adjustment rail at least approximately continuously around its circumference. The surface textures of the first and second force application surfaces are advantageously complementary to each other, for example, in the case of preferred grooves, such that they form a common recess. In other words, "approximately continuously surrounding" means that a non-edge-side recess is provided in the clamping elements in and / or through which the second adjustment rail is guided, and that the second adjustment rail is surrounded approximately around its circumference by the force application surfaces formed perpendicular to it.Alternatively, only a portion of the surrounding surfaces can be designed as force-bearing surfaces, for example, by having only a portion of the surface textured. An alternative arrangement of the recess for the second adjustment rail at the edge of the clamping elements is also conceivable, in which case the second adjustment rail is not surrounded by the force-bearing surfaces on at least one side. This allows the clamping unit to interact more stably with uneven or geometrically complex surfaces. The force-bearing surfaces can preferably have a rubber coating and / or an alternative adhesion-enhancing material.

[0045] The Fig. Figure 1 showed a cable guidance device 1 according to the invention, comprising a guide element 3 which is arranged on the base of a cable duct as the first surface 8.1 with a base 7 that is at least partially flat. The guide element 3 has a feed-through opening 4 which is semicircular and open on one side, although a polygonal and / or closed feed-through opening 4 is also possible. A cable 25 is guided through the feed-through opening 4, the inner circumferential surface of which has guide rollers 5 on which the cable 25 can slide without damage to its sheathing and / or insulation.

[0046] The guide element 3 has two first adjustment rails 9.1, which have end pieces 28. A fixing unit 2 is arranged on the first adjustment rails 9.1 between the guide element 3 and the end pieces 28. This fixing unit 2 can be moved along an adjustment direction V on the first adjustment rails 9.1 relative to the guide element 3. The fixing unit 2 includes a gripping surface, which is specifically designed as a recess on the fixing unit 2. This gripping surface allows manual engagement to adjust the fixing unit 2 along the adjustment direction V. Furthermore, the cable guide 1 has a clamping unit 6 on the fixing unit 2. This clamping element 11, formed from clamping hooks, has a first force application surface 10.1. The clamping element 11 can be positioned on a second surface 8.2 to achieve a clamping connection.The fixing unit 2 also has a release device 18, which is designed as a push button and has a surface structure, wherein the release device 18 can transfer a first locking device, not shown here, between an open and a locked state.

[0047] The Fig. Figure 2 shows a cable guidance device according to the invention with a guide element 3, comprising an at least partially flat base 7 for mounting on a first surface 8.1 and a feed-through opening 4, which is advantageously semicircular and / or open on one side, although a polygonal and / or closed feed-through opening 4 is also possible. Guide rollers 5, with a preferably curved surface, are assigned to the inner circumferential surface of the feed-through opening 4. First adjustment rails 9.1 are arranged section by section in the guide element 3, extending in the adjustment direction V. The first adjustment rails 9.1 can be designed as connecting shafts, although other embodiments, for example with flat rails, are also conceivable. On the first adjustment rails 9.1 The fixing unit 2 is arranged in such a way that it is movable relative to the guide element 3, such that the fixing unit 2 can be adjusted, in particular moved, along the adjustment direction V, thereby increasing or decreasing the distance D between the guide element 3 and the fixing unit 2.

[0048] The cable guide 1 comprises a clamping unit 6 with a clamping element 11, comprising two upper clamping hooks and one lower clamping hook, which are arranged alternately from a common origin plane, extending in opposite directions and thus advantageously forming a pincer-like arrangement. The clamping element 11 has a stretching section 27 and a first force application surface 10.1, wherein all or only some of the stretching sections 27 are advantageously designed to be at least slightly elastically resilient along the adjustment direction V, and the first force application surfaces 10.1 are located at least approximately at right angles to the stretching sections 27. This results in the first force application surfaces 10.1 being formed essentially perpendicular to the adjustment direction V. The first force application surfaces 10.1 are preferably rubberized, thereby generating static friction and propagation pressure on a second surface 8 (not shown here).2, to which the first force application surfaces 10.1 are clamped, is created. The clamping element 11 is designed to enable a clamping attachment of the cable guide device 1 to the second surface 8.2, whereby an adjustment of the fixing unit 2 along the adjustment direction V, whereby the distance D is increased, results in at least the first force application surface 10.1 of the lower clamping hook being pressed against the second surface 8.2, whereby the pressure, through the force-fit connection of the guide element 3 with the fixing unit 2, leads to a preload of the cable guide device 1, which presses the base 7 into a first surface 8.1 and thus achieves a clamping of the cable guide device 1 between the surfaces 8.1, 8.2.

[0049] The cable guide device 1 also has a release device 18, which in this embodiment is designed as a push button and has a surface structure, wherein a locking device not shown here can be transferred between an open and a locked state by means of the release device 18.

[0050] The Fig. Figure 3 shows a partial sectional view of a guide element 3 in which first adjustment rails 9.1 are arranged section by section. The guide element 3 comprises a base 7 that is at least partially flat, for mounting on a first surface 8.1, which is laterally adjacent to a through-opening 4. This through-opening is advantageously semicircular and / or open on one side, although a polygonal and / or closed through-opening 4 is also possible. Guide rollers 5, with a curved surface in particular, are assigned to the inner circumferential surface of the through-opening 4.

[0051] Two insertion openings 31 are further formed on the base 7, which are advantageously designed with an internal thread, in particular by means of a screw nut, complementary to external threads of locking pins 32, in particular socket head cap screws. The locking pins 32 are associated with support feet 33, as extensions of the base 7, whereby the complementary threads allow the locking pins 32 to be unscrewed from the insertion openings 31 to an adjustable depth in order to adjust the height of the cable guide device 1 on its base 7 to a first surface 8.1. The support feet 33 are in particular rubberized or consist of a rubber and / or rubber-like material.

[0052] In the Fig. 4a shows a fixing unit 2 with a locking device in its locked state, wherein the locking device is in the Fig. 4b is shown in an enlarged view. In the Fig. 4c shows the locking device in a complete sectional view in its locked state and in the Fig. 4d in its open state. The fixing unit 2 is arranged here on first adjustment rails 9.1, which are closed at their ends by end pieces 28, in particular end nuts. The cable guide device 1 comprises a clamping unit 6 on the fixing unit, with a clamping element 11 made of clamping hooks, shown here only in the Fig. Figure 4a shows a lower clamping hook with a stretching section 27 and a first force application surface 10.1, wherein the stretching section 27 is designed to be at least slightly elastically resilient along the adjustment direction V, and the first force application surface 10.1 is attached to the stretching section 27 at least approximately a right angle. This results in the first force application surface 10.1 being formed substantially perpendicular to the adjustment direction V. The first force application surface 10.1 is preferably rubberized, thereby generating static friction and propagation pressure on a second surface 8.2 (not shown here), to which the first force application surface 10.1 is clamped.

[0053] A locking device is formed on and / or in the fixing unit 2, which comprises a locking element 14, advantageously designed as a clamping plate, with an outer end 14.2, advantageously fork-shaped, and an inner end 14.1. The locking element 14 includes a recess 15 through which one of the first adjustment rails 9.1 is guided. Advantageously, the locking device is designed to be mirror-symmetrical on both first adjustment rails 9.1, as can be seen in the Fig. 4c and Fig. 4d. The locking device can maintain an open state according to Fig. 4d and a blocking state after Fig. 4a, b, and c, wherein the fixing unit 2 can be moved in both directions along the adjustment direction V in the open state and only in the locked state in the direction that increases the distance D. The locking element 14 is arranged on bearing means 16, which include or are designed as a fourth spring means 23, such that the outer end 14.2 is lowered relative to the inner end 14.1, or in other words, that the locking element 14 is inclined towards the first adjustment rail 9.1. This forms two clamping surfaces 30 on the inner circumference of the recess 15. The clamping surfaces 30 prevent the fixing unit 2 from moving along the first adjustment rails 9.1 in a way that reduces the distance D, while the inclined clamping allows movement that increases the distance D until the fixing unit 2 abuts the end pieces 28.

[0054] A release device 18 is provided on the fixing unit 2, advantageously in the form of a push button, particularly with a surface texture to improve tactile feedback. The release device 18 is movable relative to the fixing unit 2, in particular such that it can be moved, or in particular pressed, at least partially into the fixing unit 2. Third spring elements 22 are associated with the release device 18. These spring elements are pre-tensioned by pressing the release device 18 and, upon release of the pressure, automatically return the release device 18 to its initial position. The release device 18 further comprises a driver 29, which is advantageously designed as a circumferential collar and / or bead. When the release device 18 is pressed, the driver 29 presses against the inner end 14.1 of the locking element 14, which is lowered by the pressure.By means of a lever-like mounting of the locking element 14 on an edge element 26 (not shown here), the locking unit 14 is advantageously positioned at least approximately horizontally by actuating the release device 18, as shown in . Fig. As can be seen in Figure 4d, the clamping surfaces 30 are released, allowing movement of the fixing unit 2 along the adjustment direction V in both directions when open. Advantageously, this results in at least a slight preload on the fourth spring element 23. The lowering of the inner end 14.1 is limited, in particular, by spacers formed on the release device 18, which limit the height to which the release device 18 can be pressed into the fixing unit 2. Due to the third and fourth spring elements 22, 23 being preloaded in the open state, the locking device automatically returns to its initial position and thus to the locked state after the release device 18 has been actuated.

[0055] The Fig. Figure 5 shows a cable guide 1, wherein the device housings of the fixing unit 2 are completely removed and those of the guide element 3 are partially removed. The fixing unit 2 is arranged here on first adjustment rails 9.1, which are closed at their ends by end pieces 28, in particular end nuts. A clamping unit 6 is arranged on the fixing unit 2, comprising a clamping element 11 with a lower clamping hook and two upper clamping hooks, with a stretching section 27 and a first force application surface 10.1, wherein the stretching section 27 is formed to be at least slightly elastically resilient along the adjustment direction V and the first force application surfaces 10.1 are located at least approximately at right angles to the stretching section 27. This results in the first force application surface 10.1 being formed substantially perpendicular to the adjustment direction V. The first force application surface 10.1 is preferably rubberized, which creates static friction and spreading pressure on a second surface 8.2 (not shown here), to which the first force application surface 10.1 is clamped.

[0056] A locking device is formed on and / or in the fixing unit 2, which comprises a locking element 14, advantageously designed as a clamping plate, with a fork-shaped outer end 14.2 and an inner end 14.1. The locking element 14 includes a recess 15 through which one of the first adjustment rails 9.1 is guided. The locking device is mirror-symmetrical on both first adjustment rails 9.1. The locking device can assume an open state and a locking state as shown here, wherein the fixing unit 2 can be moved in both directions along the adjustment direction V in the open state and only in the direction that increases the distance D in the locking state. The locking element 14 is arranged on bearing means 16, which include or are designed as a fourth spring means 23, such that the outer end 14.2 is positioned relative to the inner end 14.1.1 is lowered, or in other words, the locking element 14 is arranged at an angle towards the first adjustment rail 9.1. This creates two clamping surfaces 30 on the inner circumference of the recess 15. The clamping surfaces 30 prevent the fixing unit 2 from moving along the first adjustment rails 9.1 in a way that reduces the distance D, while the inclined clamping allows movement that increases the distance D until the fixing unit 2 abuts the end pieces 28.

[0057] The fixing unit 2 includes a release device 18 designed as a push button, in particular with a surface texture to improve tactile feedback. The release device 18 is movable relative to the fixing unit 2, in particular such that it can be moved, or in particular pressed, at least partially into the fixing unit 2. Third spring elements 22 are associated with the release device 18. These spring elements are pre-tensioned by pressing the release device 18 and, upon release of the pressure, automatically return the release device 18 to its initial position. The release device 18 further includes a driver 29, which is advantageously designed as a circumferential collar and / or bead. When the release device 18 is pressed, the driver 29 presses against the inner end 14.1 of the locking element 14, which is lowered by the pressure.By means of a lever-like mounting of the locking element 14 on an edge element 26, which is designed in particular with lateral recesses for receiving the fork arms, the locking unit 14 is advantageously positioned at least approximately horizontally by actuation of the release device 18, thereby releasing the clamping surfaces 30 and allowing movement of the fixing unit 2 along the adjustment direction V in both directions in the open position. Advantageously, this leads to at least a slight preload of the fourth spring element 23. The lowering of the inner end 14.1 is limited in particular by spacers formed on the release device 18, which limit the height to which the release device 18 can be pressed into the fixing unit 2.Due to the third and fourth spring elements 22, 23 being pre-tensioned in the open state, the locking device automatically returns to its initial position and thus to the locking state after the release device 18 has been actuated.

[0058] The guide element 3 comprises a base 7 that is at least partially planar, for arrangement on a first surface 8.1, which is laterally adjacent to a through-opening 4, which is advantageously semicircular and / or open on one side, although a polygonal and / or closed through-opening 4 is also possible. Guide rollers 5, with a particularly curved surface, are assigned to the inner circumferential surface of the through-opening 4 and run, for example, on a shaft with sliding bearings.

[0059] Two insertion openings 31 are further formed on the base 7, which are advantageously designed with an internal thread, in particular by means of a screw nut, complementary to external threads of locking pins 32, in particular socket head cap screws. The locking pins 32 are associated with support feet 33, as extensions of the base 7, whereby the complementary threads allow the locking pins 32 to be unscrewed from the insertion openings 31 to an adjustable depth in order to adjust the height of the cable guide device 1 on its base 7 to a first surface 8.1. The support feet 33 are in particular rubberized or consist of a rubber and / or rubber-like material.

[0060] In the Fig. Figures 6a, b, c, d and e show a cable guide 1 in a second embodiment in various positions. The cable guide 1 according to the third embodiment can assume the same positions as the second embodiment.

[0061] The cable guide 1 comprises a guide element 3 with a base 7 that is at least partially flat and a feed-through opening 4, which is semicircular and open on one side, although a polygonal and / or closed feed-through opening 4 is also possible. The inner circumferential surface of the feed-through opening 4 has guide rollers 5 on which cables 25 can slide without damaging the sheathing and / or insulation.

[0062] The guide element 3 is rotationally connected to a first adjustment rail 9.1, the first adjustment rail 9.1 having an end piece 28 at its end opposite the guide element 3. A fixing unit 2 is arranged on the first adjustment rail 9.1 between the guide element 3 and the end piece 28, the first adjustment rail 9.1 passing through the fixing unit 2 such that the first adjustment rail 9.1 and the guide element 3 can be moved relative to the fixing unit 2 along an adjustment direction V. A release device 18 is arranged on the fixing unit 2, which can convert a first locking device (not shown here) from a locked state to an open state.

[0063] Furthermore, the cable guide 1 comprises a clamping unit 6 with a clamping element 11 having a first force application surface 10.1, wherein the clamping element 11 can be arranged on a second surface 8.2 to achieve a clamping fastening in a clamping state of the clamping element 11. The clamping element 11 is connected to a second adjustment rail 9.2, which is received in a locking unit 12 of the clamping unit 6 and movably mounted relative to it. A second force application surface 10.2 is formed on the locking unit 12, complementary to the first force application surface 10.1. The clamping unit 6 also has a release device 18, wherein a second locking device (not shown here) can be switched between an open and a locked state by means of the release device 18. A handle 17 is formed on the locking unit 12, which is connected to a push element 19 (not shown here).

[0064] The clamping unit 6 and the fixing unit 2 are connected to each other in a rotationally movable manner, in particular via an indexing joint which is not visible here.

[0065] In the Fig. Figure 7 shows a clamping unit 6 in a side view with the housing partially removed, according to the third embodiment of the cable guide device 1.

[0066] The clamping unit 6 has a clamping element 11 with a first force application surface 10.1 for clamping against a first surface 8.1. The clamping element 11 is connected to a second adjustment rail 9.2, which is movably mounted in the locking unit 12. To limit the movement of the second adjustment rail 9.2, the second adjustment rail 9.2 has a pin which is guided in a guide lug 41 of the locking unit 12.

[0067] The locking unit 12 features a second force application surface 10.2, complementary to the first force application surface 10.1. Together, the first and second force application surfaces 10.1 and 10.2 form at least an approximate clamping or clamping shape, allowing the second surface 8.2 to be clamped uniformly from both sides for a particularly stable clamping connection. The force application surfaces 10.1 and 10.2 are designed with a surface structure formed by complementary grooves, which facilitates attachment to uneven surfaces. Furthermore, the force application surfaces 10.1 and 10.2 almost completely surround the second adjustment rail 9.2, thereby increasing the clamping area and improving clamping on uneven or geometrically complex surfaces.

[0068] The locking unit 2 comprises a second locking device with a locking element 14. The locking element 14 can be, for example, a sheet metal plate or a force-fit stack of several sheets metal plates. A recess 15 is formed in the locking element 14, through which the second adjustment rail 9.2 is guided, and it is supported at its inner end 14.1 by bearing means 16 (not shown here). The bearing means 16 can be, for example, a rotating bolt that is rotationally mounted to the housing of the locking unit 12. The mounting allows the locking element 14 to rotate, with the rotation being limited by the shape of the housing of the locking unit 12. The second locking device further comprises a first spring element 20, which applies force to the locking element 14 in a locked position, in which the locking element 14 is inclined.Due to its angled position, the edges of the recess 15 press against the second adjustment rail 9.2, forming clamping surfaces 30. Because the locking element 14 is mounted at its inner end 14.1, the clamping force of the clamping surfaces 30 acts on the second adjustment rail 9.2 in such a way that movement of the second adjustment rail 9.2, and thus of the clamping element 11, is impossible when the second locking device is locked. Therefore, the first force application surface 10.1 cannot be released from the second surface 8.2 by a release movement that would increase the distance between the locking unit 12 and the clamping element 11. Since the locking element 14 has upward clearance for evasive movement—that is, in the direction that reduces the distance between the clamping element 11 and the locking unit 12—this movement is also possible when the locking device is locked.The second locking device comprises a release device 18, which in this embodiment is designed as a lever-like extension of the locking element 14 and can move the second locking device into an open state. The release device 18 is arranged at least partially outside the housing of the locking device 12 to be accessible to the user. Actuation of the release device 18 causes a partial rotational movement of the locking element 14, which positions the locking element 14 at least approximately straight or perpendicular to the second adjustment rail 9.2 and thus releases the clamping surfaces 30, thereby enabling the movement of the clamping element 11 away from the locking unit 12, thus allowing movement in both directions along the adjustment direction V.

[0069] The locking unit 12 further comprises a handle 17, which is arranged at least partially outside the housing of the locking unit 12 to be accessible to the user. The handle 17 is movably mounted such that it can be pressed inwards towards the locking device 12. Inside the locking device 12, the handle 17 is connected to a push element 19, whereby actuation of the handle 17 partially pushes the push element 19 upwards. A plate 24 is movably mounted on the second adjusting rail 9.2, which is pushed upwards by the push element 19 when the handle 17 is actuated, thereby compressing a second spring element 21. The second spring element 21 is mounted on the second adjusting rail 9.2, and upon compression, the restoring force of the second spring element 21 tilts the plate 24, which is thereby pressed against the second adjusting rail 9.2.2 is clamped and thus "engages". The clamping action transfers the thrust force exerted by actuating the handle 17 to the second adjustment rail 9.2, pushing it upwards into the housing of the locking unit 12. Actuating the handle 17 therefore allows the second adjustment rail 9.2 to be retracted into the locking unit 12, making clamping particularly easy. The handle 17 in the third embodiment is shorter than in the second embodiment and, in its initial state, is at a different angle to the clamping unit 6.

[0070] In Fig. Figure 8 shows a cross-sectional view through a fixing unit 2 with a guide element 3 and a first adjustment rail 9.1, according to the second and third embodiments of the cable guide device 1.

[0071] The guide element 9.1 has a base 7 that is at least partially flat and a feed-through opening 4, which is advantageously semicircular and open on one side, although a polygonal and / or closed feed-through opening 4 is also possible. The inner circumferential surface of the feed-through opening 4 has guide rollers 5 on which cables 25 can slide without damaging the sheathing and / or insulation.

[0072] The guide element 3 is rotationally connected to a first adjustment rail 9.1, the first adjustment rail 9.1 having an end piece 28 at its end opposite the guide element 3. Rotational movement between the guide element 3 and the first adjustment rail 9.1 is enabled by a pivot joint, wherein a mandrel 37 is arranged or formed on the first adjustment rail 9.1. The mandrel 37 has circumferential bores 40 which define preferred rotational positions. A bushing 38 is formed on the guide element 3, the dimensions of which are such that it can receive the mandrel 37, allowing the mandrel 37 to rotate but not tilt. Pressure balls 39 are mounted on the bushing 38, which can engage in the bores 40 to fix the guide element 3 in one of the preferred rotational positions.For this purpose, the pressure balls 39 are preferably mounted in recesses of the bushing 38 and, in particular, pre-tensioned by spring means such that they can be elastically pressed into their recesses to pass through the areas between the bores 40 of the mandrel 37 and, upon reaching a bore 40, are automatically moved back to their initial position to engage in the bore 40. A bead is preferably formed on the mandrel 37 which can be arranged in a complementary groove of the bushing 38 to fasten the bushing 38 and the mandrel 37 together, whereby other fastening options are also conceivable, such as locking lugs. In a particularly advantageous embodiment, the guide element 3 can be separated from the first adjustment rail 9.1, in particular with tools, thereby achieving modular interchangeability.

[0073] The first adjustment rail 9.1 has an end piece 28 at its end opposite the guide element 3, which limits the movement of the first adjustment rail 9.1 and prevents it from being completely pushed out of the fixing unit 2.

[0074] The first adjustment rail 9.1 is guided through the fixing unit 2 and movably mounted relative to it. The fixing unit 2 comprises a first locking device with a locking element 14, which can be, for example, a sheet metal plate or a force-fit stack of sheets. The locking element 14 has a recess 15 through which the first adjustment rail 9.1 is guided and is rotatably mounted at its outer end 14.2, the rotation being limited by the housing of the fixing unit 2. A first spring element 20 pre-tensions the locking element 14 into a locked position, in which the locking element 14 is inclined relative to the first adjustment rail 9.1 and presses against the first adjustment rail 9.1 with the edges of the recess 15. This creates clamping surfaces 30 at the pressure points, which prevent movement of the first adjustment rail 9.1.Upward movement, i.e., a movement that decreases the distance D between the guide element 3 and the fixing unit 2, is blocked, while downward movement, i.e., a movement that increases the distance D between the guide element 3 and the fixing unit 2, is possible. This allows the guide element 3 to be moved particularly easily into the desired position on the first surface 8.1, thereby preventing a release movement that detaches the support surfaces 7 from the first surface 8.1 and / or prevents the fixing unit 2 from sinking. A release device 18 is attached to the first locking device, which is designed as a lever-like extension of the locking element 14. By actuating the release device 18, the first locking device is moved into an open state by rotating the locking element 14 into a position at least approximately perpendicular to the first adjustment rail 9.1.This releases the clamping surfaces 30 and enables movement along both directions in the adjustment direction V.

[0075] In the Fig. Figure 9a shows a cable management device 1 with partially removed housings, according to the third embodiment of the cable management device 1 and in the Fig. 9b a cross-section through the indexing joint between the fixing unit 2 and the locking unit 12, according to the second and third embodiments of the cable guide device 1.

[0076] The indexing joint comprises two indexing discs 34, a first indexing disc 34 being arranged on the fixing unit 2 and a second indexing disc 34 on the locking unit 12. The indexing discs 34 have complementary teeth that define the possible positions in which the indexing discs 34 can be arranged relative to each other and thus determine the possible rotational positions of the fixing unit 12 and locking unit 12 relative to each other. The indexing discs 34 have a recess, particularly a central one, through which a bolt 35 is guided. The bolt 35 is connected to the fixing unit 2 on one side and closed off on the opposite side by the locking unit 12, preferably with a round nut and screw, such that the components of the indexing joint arranged between the sides cannot be detached from the bolt 35. A reversed arrangement is also conceivable.Furthermore, a fifth spring element 36 is mounted on the bolt 35, which biases the first indexing disc 34 against the second indexing disc 34, or vice versa. In its initial state, the teeth of the indexing discs 34 of the indexing joint are interlocked, thus preventing rotation. For the indexing joint to rotate, the indexing discs 34 must be pulled apart so that the tips of the teeth of the first and second indexing discs 34 can pass each other during a rotating movement. For this purpose, the teeth are advantageously designed with a rounded tip so that they can slide past each other.Pulling the components apart tensions the fifth spring element 36, causing the indexing discs 34 to return to their initial position due to the restoring force of the fifth spring element 36 when the active pulling action is stopped, and the complementary teeth slide into the toothed arrangement. Advantageously, the spring force of the fifth spring element 36 is set such that pulling the components apart, i.e., overcoming the restoring force of the fifth spring element 36, is possible manually, but the return to the initial position is nevertheless quick and reliable.

[0077] In the Fig. Figure 10 shows a cable guidance device 1 according to a third embodiment arranged on a cable box.

[0078] The cable guide 1 is positioned with the contact surfaces 7 of its guide element 3 on the base of the cable box, which forms the first surface 8.1. A cable 25 is inserted through the feed-through opening 4 and can slide along the guide rollers 5 when moved. The guide element 3 is positioned against the first surface 8.1 and is held in this position by the first locking device (not visible here). The clamping element 11 is positioned with its first force-application surface 10.1 on the side wall of the cable box, which forms the second surface 8.2, by being pushed under the edge of the side wall. Also not shown is the second force-application surface 10.2, which presses against the side of the second surface 8.2 facing away from the first force-application surface 10.1, thus achieving a clamped position of the clamping unit 11. The clamping element 11 is held in this position by the second locking device.

[0079] In the Fig. 11a and Fig. Figure 11b shows a cable guidance device 1 according to the third embodiment.

[0080] The cable guide 1 comprises a guide element 3 with a base 7 that is at least partially flat and a feed-through opening 4, which is semicircular and open on one side, although a polygonal and / or closed feed-through opening 4 is also possible. The inner circumferential surface of the feed-through opening 4 has guide rollers 5 on which cables 25 can slide without damaging the sheathing and / or insulation.

[0081] The guide element 3 is rotationally connected to a first adjustment rail 9.1, the first adjustment rail 9.1 having an end piece 28 at its end opposite the guide element 3. A fixing unit 2 is arranged on the first adjustment rail 9.1 between the guide element 3 and the end piece 28, the first adjustment rail 9.1 passing through the fixing unit 2 such that the first adjustment rail 9.1 and the guide element 3 can be moved relative to the fixing unit 2 along an adjustment direction V. A release device 18 is arranged on the fixing unit 2, which can convert a first locking device (not shown here) from a locked state to an open state.

[0082] Furthermore, the cable guide 1 comprises a clamping unit 6 with a clamping element 11 having a first force application surface 10.1, wherein the clamping element 11 can be arranged on a second surface 8.2 to achieve a clamping attachment in a clamped state of the clamping element 11. The clamping element 11 is connected to a second adjustment rail 9.2, which is received in a locking unit 12 of the clamping unit 6 and is movably mounted relative to it. A second force application surface 10.2 is formed on the locking unit 12, complementary to the first force application surface 10.1. The force application surfaces 10.1 and 10.2 are designed with a surface structure formed by complementary grooves, which facilitates attachment to uneven surfaces. Furthermore, the force application surfaces 10.1 and 10.2 surround the second adjustment rail 9.2 almost completely circumferential, thereby increasing the clamping area and improving clamping on uneven or geometrically complex surfaces.

[0083] The clamping unit 6 also has a release device 18, whereby a second locking device (not shown here) can be switched between an open and a locked state by means of the release device 18.
