Abstract

The invention relates to a cable guiding means for arrangement on a profiled bar of a profiled carrier system, which is provided with a profile engagement section to engage in a profiled bar and has a cable guiding section which is formed as a ring-like cable holder. The aim of the invention is to devise a possible way of being able to mount one or more cables of a device at the most arbitrary points one-handedly and to remove the same again without destroying the cable guiding means. This aim is achieved, according to the invention, in that the cable guiding section is displaceably insertable in respectively one groove of the profile bar and has two intrinsically rigid limbs, of which at least one is elastically deflectable, wherein the two limbs are arranged on the circumference of the cable guiding section with their end regions overlapping and, at least in an elastically deflected state of one of the two limbs, are arranged at a distance from each other.

Description

Cable guide means for placement on a profile bar

The invention relates to a cable guide means for arrangement on a profile bar of a profile carrier system, which is provided with a profile engaging portion for engagement in a profiled bar, and a cable guide portion which is formed as a ring-like cable receptacle. The invention also relates to a profile carrier system having a plurality of cooperating, different components, as described in the preamble of claim 13.

Profile constructions with standardized profiled bars from a profiled carrier modular system are widely used in industrial applications. Such profile constructions are often used, for example, widely applied to housings or support structures for production equipment, conveyors, linear motion devices, large equipment enclosures, workstation systems or even for factory automation and other applications. Such modular profile systems usually have profile bars of different lengths, corner connectors, cross pieces and a plurality of insert elements with different functions. These insert elements are intended to engage with a profile engaging element attached to them in the at least one standardized profile, often a T-slot profile, and to be releasably secured there. Profile bars of such modular profile systems are often aluminum profiles, for example aluminum square profiles, which have one or more T-slot profiles on each of their four side surfaces, usually over the entire length of the side surfaces. The present invention also relates to such profiles.

In many industrial applications, it is necessary to lay in or on a device or plant a variety of cables, pneumatic lines or the like, in particular cables for power supply and cables for signal transmission. Such applications may be in a non-exhaustive and merely exemplary list production facilities, conveyors, linear motion devices, large equipment enclosures, workstation systems or even for factory automation. The present invention is intended for such Appliances and equipment be applicable. A secure permanent arrangement of such cables is particularly necessary to avoid damage to the cables in order to avoid power interruptions and signal failures that can lead to high costs due to machine or equipment failures. In addition, these cables should be retrievable later according to a laying plan exactly at the predetermined locations in order to make any necessary maintenance, repair and replacement of cables can. Despite this requirement, in particular to ensure a secure and permanently fixed installation of such cables, the cable installation should be as uncomplicated and fast as possible in order to minimize the assembly effort and perform the assembly in the shortest possible time. Here it is helpful if the cables can be laid by the fitter with one hand and secured in particular in their intended position, since in cable installation often several activities or handling steps must be performed simultaneously. In addition, the cables should be attachable to any desired locations of support elements of the device or systems so as to be able to achieve optimal laying conditions for the wiring of a device or system.

For secure placement of such cables, cable ties are commonly used, with the cable ties attached to a nearby strut or grommet and multiple cables received through the cable tie. The ends of the cable ties are connected together by means of a non-destructively releasable ratchet connection integrated into the cable tie. However, such cable ties have the disadvantage that the ends of the cable tie can be brought together only when all cables are laid and thereby ready for detection by the cable tie. It is not possible to reopen a cable tie to insert more cables. In addition, cable ties must always be handled by two hands in the production of their closure by means of the integrated ratchet connection. Already alone for the arrangement of the cable tie thus a two-handed operation must be performed. This is time consuming and cumbersome.

There are also dimensionally stable cable clamps are known in which a leg is formed with a hinge joint, which is opposite to the rest of the cable clamp is hinged pivotally. The cable clamp can thereby be opened, one or more cables inserted and the cable clamp closed by a pivoting movement of her mobile leg again. The leg can be locked with a snap connection to the cable clamp. Also in this solution both hands of the fitter are needed for the required simultaneous handling of the cable clamp and the at least one cable.

The invention is therefore an object of the invention to provide a way by means of at least one cable management means one or more cables of a device to be mounted at any point with one hand and removed without destroying the cable routing means again.

This object is achieved in a cable guide means of the type mentioned in the present invention that the cable guide portion by means of the profile engaging portion freely positionable in a groove of the profile bars is used and two dimensionally stable, legs each having a free end, wherein at least one of the two legs elastically deflectable is and the legs are arranged in an unloaded state at the periphery of the cable guide portion with their end portions overlapping but spaced from each other and are elastically deflectable. The object is also achieved by a profile carrier system according to claims 13 to 16.

The invention thus proposes to form cable guide means such that they can be used on the one hand in a groove and freely positionable in the groove, in particular slidably, and on the other hand cables, wires and the like, for arrangement in the cable guide section by two at the cable guide portion with distance from each other arranged leg formed opening can be passed. The handling can thus be done only with one hand and without tools. Of the at least two legs, at least one of the legs should be resiliently deflectable and recoverable to increase a distance from ends of the two legs to move one or more cables between the leg ends to allow the at least one cable to be disposed in the cable guide section. In the undeflected state, the two legs should preferably have a smaller opening width than in the have deflected state, optionally also an opening width zero. The deflectability of the leg or legs should be elastic and thus recoverable, so that the original opening width of the two legs or the distance between the two leg ends sets again by the provision, which is preferably less than the diameter of the at least one Introduction to the cable management section provided cable. By such a preferred embodiment of the invention, both the arrangement of the cable guide means in the groove, its positioning and fixing as well as the arrangement of one or more cables in the cable guide section can be done with only one hand. As a result of the elastic return of the at least one, preferably the two legs, a handling step for carrying out a closing operation of the cable guide section can be completely dispensed with.

In a preferred embodiment of the invention, the cable guide portion may be at least approximately like a loop or annular, which may preferably be understood that - except for a small gap between the ends of two legs, the cable guide portion is closed in itself. Under annular so different geometric shapes can be understood, especially those in which the ring shape is composed of at least approximately rectilinear legs or at least formed using such.

A particularly stable and secure arrangement of cables in a preferred cable guide means according to the invention, in which nevertheless cables can be easily inserted into the cable receptacle with one hand, can have a substantially U-shaped part of the cable guide section. At this U-shaped section joins on each side of the upper end of the U-shape of one of the two legs, the free ends together form an expandable and resizable, insertion gap in the cable guide section for cable. The connection of the legs to the U-shape can be made in one piece with the U-shape. Particularly favorable in this case may be a structural configuration in which the connection of at least one of the preferably formed of plastic leg to the cable guide means is articulated and integral. The U-shape of the cable guide section can be designed to be particularly stable and thus provide good security against deformation or damage. By a suitable structural design of the legs and their connection to the U-shape can be achieved with little effort a reversible deflection of at least one of the two legs, thereby reversibly enlarging an opening between the leg ends for the introduction of one or more cables to enable.

In a preferred embodiment of the invention, the profile engagement element of the cable guide means may have a shaft portion which is provided for placement in a Nuthals an at least approximately T-shaped groove, and has a Hintergreifungsteil, which in turn is provided for placement in a groove bottom of the groove of the profile bar in which both the rear engagement part and the shaft part have - with respect to a first direction - a maximum width that is smaller than or equal to a width of Nuthalses the groove, and - with respect to a deviating from the first direction of the second spatial direction - at least the rear engagement part has a maximum width which is smaller than a width of the groove bottom, but larger than the width of Nuthalses. By such a configuration, it is possible to insert the cable guide means at each location of the groove in a first rotational position of the cable guide means from above into the groove, so that the Hintergreifungsteil can be passed through the Nuthals until the Hintergreifungsteil is disposed completely in the groove base. Subsequently, the cable guide means can be converted by a rotational movement into a position in the groove, in which the Hintergreifungsteil is arranged with its two ends in Hintergreifungen the groove bottom. As a result, the cable guide means is arranged with respect to the insertion direction of the cable guide means in the groove, positively in the groove. Preferably, the shaft portion is formed such that in a cross section of the shaft portion in one direction, the cross section has a length which is preferably slightly greater than the width of the groove or at most equal to the width of the groove. In this way, the sheep part can be clamped in this rotation position in Nuthals, which also takes place a fixation of the cable guide means in a direction parallel to the longitudinal course of the groove. The invention also relates to a profile carrier system with a plurality of profile bars and / or profile rails, for example, in cross-section substantially C-shaped rails, different lengths and / or different length of cross-sectional side edges of the profile bars or rails, each provided with at least one groove along its longitudinal course are, preferably profile bars and / or rails with connecting elements of the system are connected to each other. Hereinafter, profile bars and profile rails are referred to collectively as profile bars. The profile carrier system also has insert elements which are provided for use at any longitudinal positions in and along grooves of the profile bars. According to this aspect of the invention, the profiled support system is provided with an insert element which is designed as a cable guide means, as described in any one of claims 1 to 12.

In a further preferred embodiment of the invention, the profile carrier system may also have a cover rail, which is preferably releasably fixed by a clamping or snap connection on the cable guide means. In a possible preferred embodiment, for this purpose at least one surface of the cable guide means, in particular of the cable guide section, be formed with a profiling of this surface, which cooperates with a surface, in particular a profiling of an inner surface, the cover rail formed as a U-profile such that when pushed the cover rail is held on a cable guide means the cover rail by a releasable snap or locking connection on the cable guide means. Preferably, the cover rail, which is advantageously U-shaped in cross section, butts against the profile bar or rail in its latched or latched end position on the cable guide means with the ends of the two legs, in which or in which the cable guide means is inserted.

Further preferred embodiments of the invention will become apparent from the claims, the description and the drawings.

The invention will be explained in more detail with reference to embodiments shown purely schematically in the figures, in which: a perspective view of a preferred embodiment of a profile carrier system according to the invention; a perspective view of a cable guide means of Figure 1a in a first position. the cable guide means of Figure 1 b in a rotated position by 180 °. a perspective view of a profile carrier system according to the invention with a covering means with a smaller width than in Fig. 1a; a perspective view of the cable guide means of Figure 2a in a first position. the cable guide means of Figure 2b in a rotated by 180 ° position. the profile carrier system of Figure 2a without cover; the profile carrier system of Figure 3 with a fixing means fixed to the cable guide means. a profile bar of Figure 1a with a cable guide means in two different rotational positions, namely an insertion position and a fixed position on the profile bar. two cross-sectional views through a shaft portion of the cable guide means;

FIG. 7 shows two cross-sectional views according to FIG. 6 with a shaft part which has a different cross-sectional shape than in FIG. 6; FIG. 8 shows the profile carrier system from FIG. 5 with a cover rail to be pushed onto the cable guide means from above as covering means;

9 shows three representations of different phases of the introduction of a

Cable in the cable guide means; three representations of FIG. 9, but with a cable with a larger diameter. Components of a preferred embodiment of a profile carrier system are shown in FIGS. 1-10, namely profile bars 1 preferably of the same type, a cable guide means 2 inserted into the profile bar 1 and removable again, a cable tie carrier 3 integrated in the cable guide means 2, and a cable guide means 2 and / or on the cable tie carrier fixed cover profile 4. In other preferred embodiments of the invention, the invention may also be embodied with different types of profile bars 1. In the illustrated preferred embodiment, the cable guide means 2 and the cable tie carrier 3 are made entirely of plastic, for example as a one-piece plastic injection molded part. The profile bar 1 and the cover 4, however, are formed as an aluminum part, preferably as an extruded profile. The profile carrier system may comprise further components, in particular those by means of which two or more profile bars can be connected to one another, also with different orientations of the longitudinal directions of the profile bars. Likewise, the profile carrier system can continue to have inserts with other functions, which can also be used in longitudinal grooves 5 of the profile bars 1.

The profile bars 1 of the profile carrier system can be designed as per se known extruded profiles, as offered for example by the applicant. These rectangular profiles, which are preferably substantially square in cross-section, each have at least one T-shaped longitudinal groove 5, preferably centered there relative to the width of the respective side surface 6 on each of the four side surfaces 6, each preferably at least substantially over the entire length of the side surface 6 and thus also over the entire length of the profile bar 1 extends. In other than in the figures illustrated embodiments of the invention can thus be provided on one side surface of a profile bar two or more mutually parallel grooves, in particular grooves with identical cross-sectional shape.

The T-shape of the grooves 5 is formed symmetrically with respect to a parallel to the longitudinal course of the grooves and perpendicular to the respective side surface 6 extending central plane. The T-shaped longitudinal grooves 5 of all profile bars are preferably formed identically with respect to their cross-sectional shape and size, so that in all profile bars 1 preferably the same inserts, such as the cable guide means 2, can be arranged. Each of these grooves 5 preferably has a groove neck 7 which is open towards its respective side surface 6 and a groove base 8 which adjoins the groove neck 7. The groove base 8 in this case has a greater width than the Nuthals 7, whereby in each case a Hintergreifung 9 forms in the groove base 8 on both sides of the Nuthalses 7.

The cable guide means 2 shown in greater detail in FIGS. 1 a, 1 b, 1 c, 2 a, 2 b and 2 c has a cable guide section 10 in the illustration of FIG. 2 b, as well as a profile engagement section 11. The cable guide portion 10 is provided for receiving one or more cables 14, air pressure lines or the like, while the profile engaging portion is provided for placement in a longitudinal groove 5 of one of the profile bars 1 of the profile carrier system.

As can be seen, inter alia, in FIG. 9, the cable guide section 10 has a substantially U-shape, which has a base leg 15 and two equally long side legs 16, 17 which are aligned at a distance and substantially parallel to one another. The side legs 16, 17 are in this case integrally connected to the base leg 15 and have at least approximately a perpendicular to the base leg 15 alignment. The two side legs 16, 17 have a substantially straight course in the illustrated embodiment. At the base legs 15 remote from the ends of the two side legs 16, 17 each includes an upper leg 18, 19 at. Free ends 18a, 19a of these upper legs 18, 19 each point in the direction of the other upper leg 18, 19 or in the direction of the opposite side legs 16, 17. One of two upper legs 18 in this case includes in an unloaded basic position with its side legs an angle smaller than 90 °, in the preferred embodiment, the included angle is 60 °. The other upper leg 19, however, preferably closes with its side legs 17 at an angle of at least approximately 90 °. For both angles, a variety of other amounts are possible. Due to the different angles results in a non-parallel alignment of the two upper legs 18, 19. One of the two upper leg 18 in this case has a course in the interior of the U-shape, whereby the free end 18 a of this upper leg 18 a smaller distance to Base leg 15 has, as the free end 19a of the second upper leg 19. In the illustration and arrangement of the clamp-like cable guide means 2, the two free ends 18a, 19a of the upper legs 18, 19 are arranged at a distance from each other. The lengths of the two upper legs 18, 19 are in this case provided such that the two upper legs 18, 19 with respect to a direction perpendicular to the two side legs 16, 17 extending direction, at least slightly overlapping, at least slightly overlap. Between the two ends 18a, 19a of the upper leg, an opening 20 is thus formed, which is intended to introduce cables, compressed air lines and the like, in particular with a larger diameter than the opening width of the opening 20 in the cable receptacle.

Each of the two upper legs 18, 19 is integrally connected with its respective associated side legs. The respective connection point can in this case be designed as a joint 21, 22, for example in the manner of a joint integrally formed in the cable guide means joint. An integrally integrated in the cable guide means 2 joint can be realized, for example, by a reduced compared to the thighs thickness. Regardless of which concrete constructive way the upper legs 18, 19 are articulated at their respective side legs 16, 17, at least one of the two, preferably both legs 18, 19 should be elastically deflected relative to their side legs 16, 17 and thereby also after one Deflection can be reset by itself to its original position. In a deflection of the respective upper leg 18, 19 performs a pivoting movement about its respective joint 21, 22, so to the connection region between the respective side legs 16, 17 and the upper leg 18, 19, from. The two upper legs 18, 19 are in particular able to simultaneously in mutually opposite rotational or pivoting directions to perform movements.

In the region of the transitions of the otherwise provided with a substantially constant thickness side legs 16, 17 to the base leg 15, the side legs

16, 17 on their outsides a bead-like increase in thickness 24. Seen in one direction, from one side leg 16, 17 to the other side leg 16,

17, lead the two bead-like thickness increases 24 to increase the overall width of the cable guide portion 10 in this area. This bead-like increase in thickness 24 of the side legs 16, 17 are arranged symmetrically to each other on both side legs. Seen from top to bottom in the direction of the base leg, this initially leads to an increase in its overall width in this region of the cable guide section 10 until a maximum width of the cable guide section 10 has been reached. Starting from the maximum width in the direction of the bottom on the base leg 15, then then reduces the overall width of the cable guide portion 10 again.

The cable guide means 2, in the illustrated preferred embodiment, in addition to the profile engaging portion 1 1 integrally connected to the cable guide portion 10. The profile engaging portion 11 has a shaft portion connected to the base leg 15 26 and a subsequent to the shaft portion 26 rear engagement portion 27. The profile engaging portion 1 1 with its shaft portion 26 and rear engagement portion 27 has a substantially T-shape.

The T-shape of the longitudinal grooves 5 of the profile bars 1 is adapted to the T-shape of the profile engaging portion 1 1 and its cross-sectional shape such that in at least one rotational position of the profile engaging portion 1 1 in the longitudinal groove 5 results in a releasably clamped arrangement of the profile engagement portion. The T-shape of the profile engaging portion 1 1 is also tuned to the T-shape of the profiled bars 1 that at least in a certain rotational position of the cable guide means 2 with respect to the longitudinal direction of the grooves 5 of the profile engagement portion 1 1 from above in the direction of the Groove 8 is inserted into the longitudinal groove 5 until the cable guide means 2 with its underside of the Base leg 15 on the side surface 6 of the profile bar 1 in the region of the Nuthalses 7 comes into contact. By a rotation, preferably by at least approximately 90 °, of the cable guide means 2 about its longitudinal axis, which is aligned perpendicular to the longitudinal axis of the groove 5, the cable guide means 2 can be brought into a position in which the cable guide means 2 with its profile engaging portion 11 in the Nut 5 is clamped.

A possible design solution for this, can be achieved by a suitable design of the cross section of the shaft portion 26. For this purpose, a cross-sectional shape of the shaft part 26 is shown by way of example in FIGS. 6 and 7. This cross-sectional shape has a total of three pairs of parallel side surfaces 28, 29; 30, 31; 32, 33 on. The side surfaces 28, 29; 30, 31; 32, 33 are each only to the side surface 28, 29; 30, 31; 32, 33 of their pairwise arrangement in parallel. To all other side surfaces 28, 29; 30, 31; 32, 33 of the cross section of the shaft portion 26 is the respective side surface 28, 29; 30, 31; 32, 33 arranged non-parallel. The side surfaces 28, 29; 30, 31; 32, 33 are also characterized by the fact that side surfaces 28, 29; 30, 31; 32, 33 of a side surface pair each have the same length. In addition, distances from side surfaces 28, 29; 30, 31; 32, 33 different side surface pairs also different sizes.

As can be seen in Fig. 6, the side surfaces 28, 29, which are aligned parallel to side surfaces 7a, 7b of the Nuthalses 7 in the Einführrotationsposition of the cable guide means, have the greatest length and the smallest distance from each other. Their distance is less than the width of the Nuthalses 7, so as the distance of the side surfaces 7a, 7b of Nuthalses each other. In the illustration of FIG. 6, viewed in the counterclockwise direction, in each case a side surface 30, 31 of a second side surface pair 30, 31 adjoins each side surface 28, 29 of this first side surface pair 28, 29. The side surfaces 30, 31 of the second side surface pair have a smaller length, but a greater distance from each other, than the side surfaces 28, 29 of the first side surface pair. Again viewed in an anticlockwise direction, each side surface 30, 31 is followed by a surface of a third side surface pair 32, 33. The third side surface pair 32, 33 has side surfaces with the greatest distance from each other, these side surfaces 32, 33 being longer in length is as the length the side surfaces 30, 31 of the second side surface pair and is smaller than the length of the side surfaces 28, 29 of the first side surface pair. The distance of the side surfaces 32, 33 of the third side surface pair is slightly larger than the distance of the side surfaces 7a, 7b of Nuthalses each other. Finally, the transitions of the side surfaces 28, 29 of the first side surface pair to the side surfaces 30, 31 of the second side surface pair are each provided with a rounding. Likewise, the transitions of the side surfaces 30, 31 of the second side surface pair to the side surfaces 32, 33 of the third side surface pair are also provided with a respective rounding. It can also be seen in the illustrations of FIG. 6 that the side surfaces 28, 29 of the first side surface pair are aligned with side surfaces 34, 35 of the rear engagement part 27. In addition, end faces 10a, 10b of the cable guide section 10 are aligned at least approximately parallel to the side surfaces 28, 29 of the first side surface pair. As a result, a longitudinal axis of the ring-like cable receptacle 36 of the cable guide section runs perpendicular to the side surfaces 7a, 7b of the Nuthalses 7 and to the side surfaces 28, 29 of the first side surface pair.

In the illustrations of Fig. 7, a second possible embodiment of a cross-sectional shape of the shaft part is shown. Also in this embodiment, at the periphery of the cross section of the shaft portion 26, three side surface pairs each having two parallel, opposing and spaced apart side surfaces 28, 29; 30, 31; 32, 33 provided. Likewise, also in this embodiment, the lengths of the respective side surfaces 28, 29; 30, 31; 32, 33 and their arrangement and order at the periphery of the cross section of the shaft part according to the embodiment of Fig. 6 held. In contrast to the embodiment of FIG. 6 here has the side surface pair 28, 29, which should be aligned parallel to the side surfaces 7a, 7b of Nuthalses for insertion into the groove, the shortest length on the cross-sectional circumference of all three side surface pairs. The largest length of the surfaces of the side surface pairs at the cross-sectional circumference, the side surface pair 32, 33, which in this embodiment, neither in the insertion position, as shown in the left-hand illustration of FIG. 7, nor in the clamping position, as in the right-hand illustration of FIG. 7, comes into contact with the side surfaces 7a, 7b of the Nuthalses. Also, in contrast to the embodiment of FIG. 6, here the Hintergreifungsteil 27, as well as the shaft portion 26, a hexagonal cross-sectional shape. The cross-sectional areas of the shank portion and the Hintergreifungsteils are also designed and aligned with each other in this embodiment of the invention, that in a certain rotational orientation of the cable guide means of the Hintergreifungsteil through the Nuthals through- and the shank part are introduced into the Nuthals. By a rotational movement of the cable guide means by a rotation angle of at least about 45 ° after this introduction, it may - as in the embodiment of Fig. 6 - to a fixation of the cable guide means 2 on the profile bar 1, as well as an alignment of the annular cable guide portion with its receptacle for cable take place, through which the annular cable guide portion is at least substantially aligned transversely to the longitudinal course of the groove 5. In contrast to Fig. 6 is in the preferred embodiment of the invention according to FIG. 7, the cable guide means with an opposite to the embodiment of FIG. 6 direction of rotation and a smaller angle of rotation (45 ° instead of 90 °) from the respective insertion position into the groove in the respective clamping position can be transferred.

In order to guide one or more cables 14 by means of a cable guide means 2 on a profile bar 1, at least one of the cable guide means 2 is first to be inserted into one of the grooves 5 of one of the profile bars 1. For this purpose, the cable guide means 2 is inserted at a suitable point of the groove 5 from above into the respective groove 5. For this purpose, the cable guide means 2 in a rotational position in which the side surfaces 28, 29 of the first side surface pair of the shaft portion 26 are aligned parallel to the side surfaces 7a, 7b of the Nuthalses 7, with the Hintergreifungsteil ahead, inserted into the Nuthals and then into the groove bottom. As shown in Fig. 5, is located in the preferred embodiment, the cable holder 36 with its longitudinal axis substantially perpendicular to the longitudinal course of the groove 5. The profile engaging portion 11 thereby enters the groove 5 and the groove bottom 8 and, if desired, in this unchanged rotation orientation in the groove 5 are moved to any position in the groove. The depth of the insertion of the profile engaging portion 11 in the groove 5 is determined by abutting the bottom 10c of the cable guide portion 10 on the groove 5 belonging to the side surface 6 of the profile bar 1. At the stop of Bottom 10c is the Hintergreifungsteil 27 completely in the groove bottom 8 of the groove.

By a rotational movement of the cable guide means 2 of Fig. 6 about a longitudinal axis passing through the shaft and Hintergreifungsteil 27, 28, the Hintergreifungsteil 27 is rotated below and on both sides of the side surfaces 7a, 7b of the Nuthalses 7 in the undercuts 38, 39 of the groove bottom. On this rotation path by preferably approximately 90 ° (FIG. 6), first the side surfaces 30, 31 of the second side surface pair reach a position parallel to the side surfaces 7a, 7b of the groove neck 7. In the exemplary embodiment of FIG. 7, this is at a rotation angle of about 45 ° the case. At the same time, the ends of the Hintergreifungsteils 27 begin to arrange behind the undercuts 38, 39 of the groove 5. On the further rotation path of a total of about 90 ° then reach the ends of Hintergreifungsteils 27 in a position as shown in the right-hand illustration of Fig. 6, in which in this embodiment of the invention, a longitudinal axis of the Hintergreifungsteils 27 at least approximately perpendicular to the longitudinal axis and is aligned with the longitudinal course of the groove 5. By a suitable design of the undercuts 38, 39 opposite surfaces of the undercut 27 can also be achieved that the cable guide means 2 between the side surface 6 of the profile bar 1 and the surfaces of the undercuts 38, 39 elastically tensioned and thus held in position on the profile bar , By a rotational movement in the opposite direction, the cable guide means 2 can be solved again on the profile bar 1 and subsequently removed by lifting from the groove 5. These manipulations of the cable guiding means 2 can be carried out with only one hand of the user.

After a cable guide means 2 has preferably been used with one hand in a profiled bar 1 and attached to this as described, the cable guide means 2 for receiving one or more cables 14 is ready. The distance of the free ends 18a, 19a of the two upper legs 18, 19 is preferably matched to the diameter of the at least one male cable 14 such that in the unloaded state of the two legs 18, 19 of the smallest distance between their ends 18a, 19a is smaller than the diameter of the at least one too The cable 14, which is approximately parallel to the profile bar 1 and lengthwise, can be pushed transversely to its longitudinal direction between the two upper legs 18, 19 and into the receptacle. As shown in FIGS. 9 and 10, in this case, the leg 18a inclined obliquely downward into the receptacle can be used to guide the cable 14 towards the opening. By doing so exerted on the cable 14 pressure by a user experiences this leg 18 a deflection down in the direction of the cable receptacle 36 inside. If the cable 14 then continues to the opening is pressed by continuing to be applied to the cable 14 pressure, the cable between the ends 18a, 19a of the two upper legs 18, 19, whereby the upper leg 19 is deflected upward. By taking place opposite to the deflection of the upper leg 18 deflection of the upper leg 19 is an enlargement of the opening or the distance of the free ends 18 a, 19 a, whereby the cable 14 is inserted into the receptacle. The size of the deflections are dependent on the size of the respective cable diameter. The two upper legs 18, 19 pivot through the relief taking place thereby back to their starting position, in which their distance and thus the opening formed by them again assume the output. The once introduced cable 14 can not easily escape from the cable guide means 2 again. Also, the discussed introduction of the cable can be performed by a user with one hand. In order to remove the cable from the cable guide section, the cable must be pressed deliberately against and with force through the opening.

In the manner described in particular a plurality of cables 14 and with different diameters can be introduced into the cable receptacle 36. As soon as all provided cables are located in the cable receiver, they can be additionally secured in the preferred embodiment according to the invention by means of a cable tie 40. For arranging and receiving the cable tie 40 directly next to the cable receptacle 36, the cable guide section 10, in particular the base leg 15, may be provided with a cable tie receptacle 41. For this purpose, preferably the base leg 15 - with respect to its position in a fixed in the groove 5 arrangement - in a direction parallel to the longitudinal course of the groove 5 have a greater depth than the side legs 16, 17. The opposite the side legs projecting portion of the base leg 15 preferably provided on its underside with two spaced-apart webs 42, 43 which have a slot 44r 45. The slot 45 may be provided for the implementation of the same cable tie 40, which is thus guided around the underside of this portion of the lower leg 15 by means of the webs 42, 43 and is permanently closed above the lower leg 15 with its ratchet connection. The cable tie 40 can in this case be tightened so far that the cable tie 40 abuts against at least some of the cable 14 and presses the cable in position against the cable tie receptacle and fixed. In a further embodiment of the invention, the optional cable tie receptacle 41 can also be provided as a separate component as part of the profile carrier system. This component should be provided with a profile engaging portion 11, which may be formed in the same manner as the profile engaging portion 11 of the cable guide means 2. Thus, to avoid repetition on the Fig. 5 to 7 and to the comments on the structural design of the profile engagement portion 11 of Cable guide means 2 and its interaction with the longitudinal groove 5 referenced.

In order to protect the cable from possible damage and also to achieve a visually appealing design with non-visible cables 14, pressure lines and the like, the profile support system may have a cover 4, such as a cover rail, which is releasably attachable in particular by means of a snap connection on Prpfilstab and also covers the cable management means. The cover rail 4, which is designed in particular as an extruded aluminum profile, may be U-shaped in cross section, with two side cover legs 48, 49 of the U profile being aligned substantially perpendicular to the main cover leg 50. Each of the two Seitenabdeckschenkel 48, 49 has at its free end 48a, 49a on the inside of the free end 48a, 49a in the direction of the Grundabdeckschenkel 50, a continuous increase in thigh thickness, from a maximum thickness 51, 52 again up to a decreases constant leg thickness, with which the respective Seitenabdeckschenkel 48, 49 then continues to Grundabdeckschenkel 50. The resulting different distances of the inner sides of Seitenabdeckschenkel 48, 49 are so to the different widths of the cable guide portion 10th in the area of the transitions of the side legs 16, 17 tuned that the cover rail 4 from the top with the free ends 48a, 49a of Seitenabdeckschenkel 48, 49 ahead of a, preferably several, cable guide sections 10 are postponed. Here, the smallest distance of the two inner surfaces in the region of the maximum leg thickness 51, 52 of the Seitenabdeckschenkel 48, 49 may be only slightly larger than the distance between the outer surfaces of the side legs 16, 17 above the bead-like bulges or thickenings 24. Once the ends 48a, 49a of the Seitenabdeckschenkel 48, 49 reach the bead-like thickening 24 of the side legs, the free ends 48a, 49a of the Seitenabdeckschenkel be deflected. As soon as the locations of the maximum limb thickness 51, 52 reach the largest bulges of the bulge-like thickenings 24 of the side limbs 16, 17, the side cover limbs 48, 49 are deflected outwardly and at least slightly elastically in opposite directions. Once the locations of the maximum leg thickness 50, 51 have passed the locations of the largest bulges, the Seitenabdeckschenkel 48, 49 swing back and the points of the maximum leg thickness 51, 52 engage behind the points of greatest thickness increases 24 or bulges, whereby the cover rail 4 at the cable guide portion 10 is held in the manner of a snap connection.
