Description

The invention relates to a holding segment for the detachable connection to at least one further holding segment or to a connecting element, and to the connecting element for the connection of at least one holding segment to a support column. The invention further relates to a receiving channel for at least one line comprising the connection element and a plurality of holding segments connected thereto, and a holding device comprising a base and a connection element connected to holding segments. Finally, the invention relates to the use of the holding device for guiding at least one first line.Technological BackgroundIn the working day of hand workers and in industry, contamination and the generation of dust frequently occur. Some fields of application can produce dust particles from stone materials or also from organic materials such as wood when using tools for surface machining and / or chip removal. For reasons of hygiene and in order to avoid health risks such as allergies or asthma, it is important to remove dust which arises from the working or whereabouts. Thus, various machines have been developed from the prior art which are suitable for dust removal. In this way, exposure of people operating the machines can be minimized.Mobile suction modules or industrial dust removers have been developed to ensure the protection of the health of the hand workers and the hygienic standards.The industrial dust collector is typically connected to the tool by means of a hose, and in parallel partly additionally to an electrical or a pneumatic line. These connecting lines are guided predominantly lying on the ground and the basic problem arises here of collisions with the user or damage to the lines themselves or for twisting the lines with one another. Guidance of the lines away from the ground is therefore the basic object of the invention.In this case, the lines necessary for the operation of the tools and suction modules form obstacles and / or risks for people in the above-described working environment.The invention is therefore based on the object of further developing holding segments and a connecting element for forming a receiving channel and a holding device for at least one line, while avoiding the aforementioned disadvantages, wherein the receiving channel and holding device is variable in length in particular and unintentional breaking off of the receiving channel is avoided in the case of a moving line. In particular, the holding device should be securely, firmly and stably fixable on its holding part to the so-called connection element. In addition, the holding device should be easily disassembled and can be cleared in a simple and space-saving manner.Starting from the prior art, it is therefore an object of the present invention to provide a connecting element for a plurality of holding segments in order to be able to connect a plurality of holding segments, which form a receiving channel, to a supporting column.Depending on the weight, length and movements of the line or lines to be accommodated in the accommodation channel, deflections may occur in the accommodation channel. If forces are too high between the connection element and the free end of the receiving channel, the holding segments of the receiving channel may open and two holding segments may fall apart at any point of the receiving channel. Therefore, a targeted disconnection of the connection between the connection element and the holding segment connected thereto would be desirable. Alternatively, a predetermined breaking point or predetermined opening point can be provided on the holding elements, so that the holding segment connected to the connection element fails.Therefore, it is a further object to design the connection element for a plurality of holding segments such that forces acting on the connection point due to lever forces acting at the distal end of the receiving channel and due to bending load of the forces acting along the longitudinal axis up to a predefined load threshold can be absorbed such that in the event of overload a defined opening is provided on the connection element, in particular on a holding segment connected to the connection element. In this way, a controlled interruption of the receiving channel at the height of the connection element can be made possible, so that the remaining receiving channel, consisting of the holding segments, is retained over its entire length and no damage to the individual elements occurs. The user can re-join the channel without tools and completely recover the original function; accordingly, it is a completely reversible and defined opening function in the event of mechanical overload. Due to the flexibility of the individual links or retaining segments of the receiving channel, this function is designed such that the now free, non-supported chain of retaining segments can yield flexibly and the user always remains protected.DESCRIPTION OF THE INVENTIONThe present invention is intended to achieve the above objects better than conventional devices and systems.These objects are achieved with the aid of a holding segment for releasable connection to a plurality of further holding segments for forming a receiving channel, a connecting element and a holding device according to the features of the independent claims. Preferred embodiments of the invention result from the dependent claims which follow the independent claims and the subordinate use claims.According to a first aspect of the invention, a holding segment is provided with a receiving channel for at least one first line extending along a longitudinal axis of the holding segment, wherein the holding segment can be detachably connected to at least one further holding segment and / or to a connecting element in order to lengthen the receiving channel. The holding segment has an upwardly open profile with two legs which are connected to a channel element running transversely to the longitudinal axis of the holding segment, wherein both legs have first side walls and second side walls, preferably projecting beyond the channel element in the direction of the longitudinal axis, and wherein the first side wall is arranged in each case offset to the respective second side wall by at least one wall thickness parallel to one another. Furthermore, each first side wall has a latching element in each case and each second side wall has a cutout corresponding to the latching element, preferably for receiving a latching element of a further holding segment, and wherein the channel element is formed in such a way that center points formed by the latching elements and / or the latching elements are arranged in the upper half of the upwardly open profile of the holding segment. In particular, a channel element can be understood to mean a transverse web which runs transversely to the longitudinal axis of the holding segment and connects the legs, or a connecting element.This results in the advantage that no tools are necessary for the assembly of the holding segments. With the aid of the latching elements and associated recesses, the retaining segments can be easily connected to one another and a receiving channel of different lengths can be formed. Thus, the length of the receiving channel can be individually extended or shortened for the respective requirements. Due to the fact that more than the upper half of the latching elements are arranged in the upper half of the holding segment and thus the channel element is at least partially spaced apart from the side walls downwards, the free ends of the legs can be bent more easily towards one another. Due to a simpler flexibility, the latching elements can be guided more easily into the respective opposite recesses of the closest holding segment.According to a preferred embodiment of the holding segment, it is provided that a maximum distance of the channel element or transverse web from an axis of rotation, which is aligned with the center points of the respective latching elements, in the direction of the height axis of the holding element is greater than the height of a leg and / or the height of one of the first or second side walls. Alternatively or additionally, a length of the channel element or transverse web along the central axis of the channel element, wherein the central axis runs transversely to the longitudinal axis of the holding segment, is longer than the distance between the legs. In this way, the channel element is formed spaced apart downward. Thus, an elastic bending profile part for the exact fitting engagement of the latching elements in the corresponding recesses preferably of a further holding segment is advantageously provided.The above-described configuration of the holding segment results in flexibility and flexibility of the legs, in particular in the upper region, in each case two holding segments can be easily joined together with one hand, i.e. with a simple gripping movement with two or more fingers or can be separated from one another again.Plastic can be used as a suitable durable flexurally elastic material for the retaining segments, wherein the plastic is selected from the group of polyamides, polypropylene, polyethylene, polystyrene and acrylonitrile butadiene styrene (ABS).According to a further preferred embodiment, the channel element is connected to the respective legs in such a way that the legs enclose obtuse angles between 90° and 180° with the channel element or transverse web, wherein the legs are preferably arranged parallel to one another. Furthermore or alternatively, the channel element or the lower region of the legs preferably has a first contact section.By means of a mutually inclined transverse web surface or mutually inclined surface of the channel element at an angle of greater than 90° with respect to the legs, the accommodated line can be easily centered and guided in the accommodation channel. The greater the obtuse angle selected, the greater the maximum distance of the channel element or the transverse web from an imaginary planar transverse web between the opposite lower edges of the legs and / or from the axis of rotation which is aligned with the center points of the respective latching elements, so that a compression of the legs relative to one another is facilitated.According to a further preferred embodiment, the first side walls are arranged in the longitudinal axis on one side of the channel element or of the transverse web and the second side walls are arranged in the longitudinal axis on the opposite side of the channel element or of the transverse web and / or the side walls each have a maximum longitudinal extent which corresponds to the distance in the direction of the longitudinal axis of the holding segment between the centre point of the latching element and a centre point formed by the cutout.In this way, the holding segment can form a receiving channel with a plurality of holding segments, which receiving channel remains open on one side and enables the insertion of one or two lines. The recesses are preferably designed as circular blind holes or holes. The connection to the corresponding latching elements can thus be easily produced and released in order to form a variably extendable or retractable receiving channel.According to a further preferred embodiment, the channel element has, at least in sections, a guide channel with a lowered region, wherein the guide channel preferably protrudes beyond the channel element or the transverse web on one or both sides in the direction of the longitudinal axis of the holding element.In this way, the holding segment or the receiving channel formed by a plurality of holding segments can receive a second line which is received by the guide channel and has a smaller second diameter than the first diameter of the first line which is guided between the mutually facing side walls of the holding segments.According to a further preferred embodiment, the first contact section and a second contact section are arranged on the ends of the guide channel opposite one another in the direction of the longitudinal axis, wherein the first contact section and the second contact section each have an end face which is respectively intended for contact with a further holding segment or the connection element.The guide channel thus has contact sections, on the respective end faces of which a corresponding end face of a contact section of a further holding segment can abut. In this way, a continuous guide groove is formed for receiving a second line. By providing stop sections, the movability or pivotability of the holding segments relative to each other is limited. This has the advantage that the receiving channel formed by a plurality of holding segments is not flexible in all directions and can form a stable guide channel when the respective end faces of the contact sections of the holding segments abut against one another.According to a further preferred embodiment, a / the guide channel protrudes on both sides beyond the channel element and / or the maximum distance of the second contact section from the channel element is less than or equal to the maximum distance of the first contact section from the channel element or from the transverse web.If a shorter distance or a shorter length of the one contact section (in the direction of the longitudinal axis of the holding segment) is provided to the channel element or transverse web in comparison to the distance or the length of the other contact section (in the direction of the longitudinal axis of the holding segment), the receiving channel is curved downward in the direction of gravity. In other words, the latching elements of adjacent retaining elements are further away from one another than the contact sections or end faces of adjacent retaining segments which point in the same direction. In contrast, in an embodiment with maximum distances of the respective contact sections of equal length (in the direction of the longitudinal axis of the holding segment) to the channel element or transverse web, a receiving channel has a straight receiving channel or a receiving channel which is not curved in the direction of gravity.According to a further preferred embodiment, the guide channel and / or the profile of the retaining segment has a symmetrical shape with respect to its central longitudinal plane.Due to the symmetrical shape, the respective lines can be guided in a centered manner in the receiving channel and optionally in the guide channel and the load distribution can be optimized. This central guide distributes the weight of the line guided in the receiving channel uniformly to both sides of the central longitudinal plane, so that the receiving channel does not tilt to one side when the line is straight, i.e. does not get a strike side to one of the side walls.According to a further preferred embodiment, the side walls are arranged at a clear minimum distance from one another in order to accommodate a first line having a first diameter smaller than the clear minimum distance and the guide channel has a profile in order to accommodate a second line having a second diameter smaller than half the first diameter, wherein the profile is preferably formed as a U-shaped profile and the second diameter is smaller than twice the rounding radius of the U-profile.In this way, for example, an energy line can be accommodated in the guide channel and a line with a substantially larger circumference, such as a hose for transporting air and / or dust or other media, can be arranged above the guide channel.According to a further preferred embodiment, the side walls form an offset by at least one wall thickness, wherein the offset of the side walls each form a limiting surface for the pivotability of a further holding segment connectable to the holding segment.In this way, the offset of the side walls can simultaneously form a limiting surface or a stop, which limit the pivoting movement of adjacent holding segments with respect to one another. Depending on the embodiment, only parts of the offset can also serve as a boundary surface.Furthermore, a connecting element for connecting at least one holding segment to a support column is provided, which comprises: a proximal end with a first opening for supporting the connecting element on the support column; a distal end with an abutment section for a holding segment; and two holding ears each with a recess or a latching element for connecting to a corresponding latching element or recess of the at least one holding segment.The connection element can advantageously be used to enable a stable and secure connection to other holding systems, such as a stable base. However, it should also be taken into account that a specific disconnection of the connection between the connection element and the holding segment connected thereto is desirable.The connection element is therefore designed such that lever forces acting on the connection point with the connection element can be absorbed up to a predetermined load threshold on account of lever forces acting at the distal end of the receiving channel. If the load threshold is exceeded, a desired opening location is provided on the connection element. In this way, a controlled dropping apart of the preferably complete receiving channel at the height of the connection element can be made possible, so that the part of the receiving channel formed by the holding segments is retained in its entire length and does not break down in an uncontrolled manner into individual holding segments.If the connection element is connected to a support column, this support column can be connected, for example, to a stand or a wall holder. In this way, the connection element represents a universally usable connection piece, so that a receiving channel made of holding segments and connection element can be used for many functions and at the same time can be adapted to different user requirements.According to a further preferred embodiment, the first opening is at least partially circular and / or formed by at least one section of a circle segment in order to rotatably support the connection element about a support column section of the support column.If the first opening is circular, the user can rotate the receiving channel 360° about the support column, wherein the support column is designed or fastened such that the receiving channel for lines of a tool can be guided, for example, over the head height of the user. Thus, simple handling of tools for surface machining is possible, wherein lines connected to the tool no longer interfere with the accommodation in the accommodation channel or no longer stand in the way for certain movements. Furthermore, the working safety can be increased since the handman can no longer trip over conduits located on the ground.According to a further preferred embodiment, a preferably circular second opening is arranged between the first opening and the distal end for passing through at least one first line. In a further advantageous embodiment, a distal edge, which is arranged between the holding ears and is preferably circular, second opening, has a guide channel along a longitudinal axis of the connection element for the second line.In this way, one or two lines, which are guided from the retaining segments into the connection element, can be guided through the second opening downwards along the support column. Thus, an unintentional falling out of the at least one line upward can advantageously be avoided and furthermore the holding segments can all be designed identically. Thus, one or more lines can be guided through the second opening of the connection element and subsequently guided further in the distal direction in the receiving channel formed from identical holding segments as far as its free end without the lines having to be led out of the receiving channel either upwards or laterally. In addition, if a guide groove is provided in the distal edge between the holding ears, the guide groove of the receiving channel may be continued continuously for better guiding of e.g. a cable.According to a further preferred embodiment, the connection element has a reinforcing rib which runs from an upper edge of the proximal end to the distal end of the connection element.The reinforcing rib gives the connection element more stability, so that in the event of a high load, a desired opening location is defined at the distal end of the receiving channel, i.e. at its free end which is not connected to the connection element, between the connection element and the holding segment connected thereto. The connecting element with the reinforcing rib can be produced easily by injection molding.Furthermore, a receiving channel for at least one line is provided, wherein the receiving channel comprises a connection element and a plurality of holding segments connected thereto. In this case, the length of the receiving channel can be extended by connecting a holding segment to further holding segments. Furthermore, the receiving channel is pivotable about axes of rotation extending in the transverse direction of the receiving channel, which axes of rotation are aligned with the center points of the respective recesses, from a use position into a folded-in position.In this way, a flexibly expandable and retractable receiving channel is provided, the holding segments of which can be pivoted from a stable use position into a folded-in position. The receiving channel has a part which can be rolled in in the direction of the connection element. The individual holding segments can only be pivoted in one direction and toward the next holding segment about the respective axis of rotation. In this case, the end faces of the bearing sections of the guide channel that bear in the use position can move away from one another until they reach a desired folded-in position.According to a further preferred embodiment, the receiving channel assumes a straight course in the use position or from a course concave on the transverse web side or channel element side and / or curved in the direction of gravity, wherein the first contact section of the holding segment or the end face arranged thereon contacts the second contact section or the associated end face of the further holding segment.The transverse web side or guide inner side is understood to mean that side which lies opposite the side walls in the height direction. The inside of the guide is the closed side of the upwardly open profile of the holding segment, which is upwardly open.The rectilinearity of at least the movable or rollable part of the receiving channel or a curved course can be produced by providing maximum distances of the contact sections of a holding segment of equal length or different length from the channel element or transverse web.According to a further preferred embodiment, the free end of the receiving channel can be rolled into the folded-in position in the direction of the connection element, wherein preferably retaining segments lying one above the other can be held or nested in the folded-in position; and / or wherein preferably each retaining segment can be pivoted at most through 90° with respect to the adjacent connection element or retaining segment.Because the receiving channel can be rolled in from the free end, the receiving channel can be cleared up in a space-saving manner. Due to the nestability of holding segments lying one above the other, space can be saved. If, in the folded-in position, the respectively adjacent contact sections of the holding segments no longer touch, the rolled-in part of the receiving channel takes on a worm shape as it were. Depending on the size of the container or the space at which the receiving channel is to be stowed, this "scroll shape" may be deviated from.According to a further preferred embodiment, the holding segment and / or the connecting element is produced from a plastic material; wherein preferably at least portions of the guide channel and / or of the channel element or transverse web can have a friction-increasing coating or a friction-increasing surface, in particular within the receiving channel.In this way, the lines in the receiving channel or in the guide channel slide less easily and improve handling when a tool connected to the lines is moved. With the aid of the friction-increasing surface, the lines cannot slip rapidly, unpredictedly, along the longitudinal axis of the receiving channel or laterally. The advantage is thus also that no further functional elements are required for clamping or securing the line or lines.According to a further preferred embodiment, a holding device is provided which comprises a support column and a receiving channel, wherein the connection element is mounted rotatably with respect to the support column.According to a further preferred embodiment, the holding device comprises a base for holding the support column, wherein a support column section is arranged in the first opening of the connection element; and the connection element is mounted on a circumferential flange of the support column such that it can rotate about an axis of the support column.In this way, the receiving channel can preferably be rotated through 360° and the tool lines received therein can be rotated about the support column and allows the user great freedom of movement when handling his tool. The support column can be fastened on a base such as a stand or on a wall holder in order to be able to hold the receiving channel for the one or more lines so high that the operator of the holding device is disturbed as little as possible during his work with the tool connected to the lines. Trouble-free work can take place in particular if the receiving channel is attached above the head height of the user.According to a further preferred embodiment, the support column has a locking means, in particular a locking pin, at the end of the upper support column section in order to prevent the connection element from slipping out in the direction of the free end of the support column and / or the lower support column section has an internal thread for connection to a base by means of a connection screw, wherein the base is selected from a group comprising: a stand, a perforated plate, a table, a workbench, a toolbox with perforated plate and a wall holder.The locking device, in particular the locking pin, is preferably prestressed with a spring, so that the locking pin automatically protrudes beyond the outer circumference of the first support column section and can thus secure against the connection element slipping out.The support column can advantageously be combined with different base elements, it also being possible to use mobile toolbox towers or other units with rollers.Furthermore, the use of a holding device for guiding at least one first line is disclosed, wherein the first line is passed through the second opening of the connection element and is accommodated in the receiving channel. Furthermore, the at least first line protrudes distally from the receiving channel, wherein the holding device is rotatable about the support column as a result of movements of the distal end of the receiving channel of the at least first line.In the use position, the receiving channel movable about the support column cooperates with the movements of a tool connected to the hose, in particular to the effect that the receiving channel can be aligned in the direction of the tool by rotation about the support column.According to a further preferred embodiment, the use of the holding device for guiding a first line is disclosed, which is preferably designed as a suction hose with a (first) diameter of at least 20 mm. Furthermore, the holding device is used for guiding a second line, wherein the second line has a smaller (second) diameter than the diameter of the first line; and the second line is preferably an electrical connecting cable for supplying a tool, preferably for surface machining and / or chip removal, and is preferably guidable in a / the guide channel of the holding segments or of the connection element.Brief Description of the FiguresFurther features and advantages of the invention are evident on the basis of the following drawings, in which advantageous exemplary embodiments of a retaining segment according to the invention, connection element, receiving channel retaining device, and a method for forming a receiving channel and the use thereof are illustrated by way of example, without restricting the invention to the exemplary embodiments shown.

The x-axis extends in the longitudinal direction of the receiving channel. As the height axis or height direction of the holding element, an axis or direction oriented parallel to the side walls and perpendicular to the longitudinal axis of the holding element is used. The height direction can also be referred to as the y-direction. The z-axis extends perpendicularly from one side wall to the opposite side wall. The central plane of the holding segment is spanned by the x- and y-axes and extends centrally between two side walls opposite one another in the y-direction. The central plane can also be referred to as a plane of symmetry. The central axis of the holding segment extends along the y-axis in the central plane and can also be referred to as the axis of symmetry S. The central axis of the channel element is parallel to the z-axis and extends transversely to the longitudinal axis of the holding segment, which extends parallel to the x-axis.The term "proximal" is used to describe a position of an element of the receiving channel or the holding device. The proximal end of the receiving channel denotes, for example, the end of the receiving channel which can be fastened to a base, while the distal end of the receiving channel is the opposite free end of the receiving channel which is not connected to the base. Further, the term "exemplary" or "e.g." is used herein to describe an example of a possible embodiment of the invention. The embodiments illustrated in the drawings represent merely examples of how the apparatuses according to the invention, such as holding segment, connecting element or holding apparatus and methods, can be configured and do not represent a final limitation of the invention.The representations are schematic and not necessarily to scale. Moreover, they do not show all details, but are limited in part to the representation of the details essential to the invention and further features which facilitate the explanation and description of the invention. Like elements in the different figures are denoted by like reference numerals. For the sake of easier comprehension, not all elements are provided with reference symbols in all figures. That is to say that for the sake of clarity only reference numerals are used in the individual figures which are required for the description of the respective figure.FIG. 1 shows a front view of an exemplary embodiment of a retaining segment according to the invention with an open-top profile. The holding segment is identified by the reference sign 110. The holding segment 110 has two legs 111 and 112 which are connected to a channel element 116 or transverse web running transversely to the x-axis or transversely to the longitudinal axis x 160 of the holding segment 110. The channel element 116 thus extends in the direction of the z-axis, wherein the length along the channel element 116 in the z-direction is longer than the distance z 110a( see double arrow) between the legs 111, 112. The dash-dotted line z 116 indicates the possible course of a planar transverse web or channel element. Compared to the dot-and-dash line z 116 the gutter member 116 is spaced downward. In other words, the channel element 116 is spaced apart downward from an imaginary planar channel element or transverse web and, in the embodiment shown, is additionally curved downward in a partial region.The downwardly curved region of the channel element 116 is arranged centrally on the central axis of the holding segment in this embodiment and is designed as a U-profile. In other words, a guide channel 160 is formed on both sides of the axis of symmetry S, which channel has a lowered region with respect to the channel element surfaces or transverse web surfaces inclined with respect to the y-axis and adjoining the side walls. The guide groove 160 has a width Z U which corresponds to twice the rounding radius r U of the U profile and has a curved partial region 163. The rounding radius r U of the curved sub-region 163 is selected such that the guide groove 160 can accommodate a line having a radius r K, which is smaller than the rounding radius r U of the U profile. The double radius r U corresponds to a receiving cross section or diameter D U( D U= 2* r U) and the distance z U, which is shown in FIG. 1 as a dashed double arrow.The maximum height y 110 of the holding segment 110 parallel to the y-axis is halved at the height of the dashed line 115. As shown in FIG. 1, the channel element 116 or the transverse web is at least partially spaced apart from a planar channel element or transverse web, which extends exclusively parallel to the z-axis or along the dot-dashed line z 116 in such a way that the center points M 141 and M 142 of the latching elements 141 and 142 are arranged in the upper half of the upwardly open profile of the holding segment, i.e. above the bisecting dashed line 115. The channel element 116 is angled with respect to both legs 111, 112 and curved in sections such that a maximum distance of the channel element or transverse web from a planar channel element or transverse web of at least half the height of a leg (y 111, y 112) is formed.The retaining segment 110 has a symmetrical cross section and each leg 111, 112 encloses an angle α with respect to the channel element or the transverse web 116. The legs 111, 112 are arranged parallel to one another at a distance z 110a( see double arrow). The height extension y 110( see dashed double arrow y 110) of the holding segment 110, runs along the y-axis. The first leg 111 has a height y 111 and the second leg 112 a height y 112 wherein the leg height is measured in each case in the inner side of the open profile. The center point M 141 of the latching element 141 is arranged at half the height of the limb 111, while the center point M 142 of the latching element 142 is located on the opposite outer side of the limb.FIG. 2 shows a perspective view of the exemplary embodiment of FIG. 1. each leg 111, 112 has two side walls 111 a / band 112 a / b. In the middle of the height y 111 or y 112 of the respective side wall 111 aand 112 b,latching elements 141 and 142 are arranged. The reference symbol M 142 identifies the center point of the latching element 142 (compare latching element 141 on the side wall 111 awith reference symbol M 141 in FIG. 1 ). Each latching element 141, 142 is suitable for engaging in a corresponding recess 121, 122 of a further retaining segment 110' (not shown here) or of a connection element (not shown here; see reference sign 210 in FIG. 5 ) in order to detachably connect to the respective retaining segment. In this case, the second side wall 112 ais arranged offset by an offset 126 (see also double arrow x 126, which indicates the extent of the offset in the x direction) of at least one wall thickness parallel to the second side wall 112 bto enable optimum latching of the latching element 142 into the corresponding recess 122 of an adjacent retaining segment. The extent x 126 of the offset 126 is illustrated from above in the subsequent FIG. 3.FIG. 2 shows a perspective view of the holding segment. In this view, details of the gutter member 116 and the guide gutter 160 are shown. The guide channel 160 has a first contact section 161 at least at one end in the region of the apex through which the axis of symmetry S of the U-profile and of the holding segment 110 runs. In the embodiment shown, the contact section 161 protrudes beyond the channel element or the transverse web and extends in the direction of the longitudinal axis x 160. The contact section 161 has an end face 136 which, in this embodiment shown, runs transversely to the longitudinal axis x 160. Other configurations of the contact section 161 are conceivable. For example, the edge section and thus the contact section of the channel element or transverse web 116 can be shaped as a bulge.In the perspective illustration of FIG. 2, the center point of the cutout 122 has been identified by the reference symbol M 121. The center M 121 and the center M 122 of the opposing recess 122 have the axis z 121. as a common axis. The centers M 141 and M 142 of the latching members 141 and 142 each have an axis z 141 and z 142, which are aligned with each other. As soon as the latching elements 141, 142 are inserted into the corresponding recesses 121, 122 of a further holding segment or of a connection element (not shown), the axis z 141 or the axis z 142 forms an axis of rotation. The latching elements 141, 142 are designed with a circular outer diameter for easy rotation of the holding segments with respect to one another. The latching elements 141, 142 can also have different shapes than those shown here.The free ends of the side walls 111 a, 111 bof the leg 111 are formed along the longitudinal axis in a semicircular manner with a radius r 111a for a rotation of the holding segments with respect to one another. The offset 125 forms a stop step. If a further holding segment is latched in for connection via the latching elements 141 and 142, the further holding segment, which is not shown here, can be rotated as far as the vertical stop step or offset 125 on the side of the first limb 111 or as far as the stop step or offset 126 on the side of the second limb 112. The stop step or offset 126 has a thickness x 126.The side walls 111 a / band 112 a / barranged on the channel element 116 each run parallel to the central longitudinal plane of the holding segment. The central longitudinal plane runs through the longitudinal axis x 160 and runs through the apex and the axis of symmetry S of the guide channel 160. The stop steps or offsets 125 or 126 are formed by the outer side walls 111 band 112 band have a width x 125 or x 126 respectively. Each stop step has a curvature at its base for transition to the respective limb 111 or 112. The height of the stop step 126 is therefore slightly less than the height y 112a of the side wall 112.FIG. 3 shows a plan view of the exemplary embodiment according to FIGS. 1 and 2 The dot-dash line identifies the central axis z 1 of the channel element 116. The minimum length of the transverse web in the x-direction is marked with L 116 and a dashed double arrow. The first contact section 161 of the guide channel 160 extends in the direction of the longitudinal axis x 160.In the exemplary embodiment shown, the guide channel 160 is formed protruding beyond the transverse web 116 on both sides. The second abutment portion 162 may have the same extent x 162 as the extent x 161 of the first abutment portion. Alternatively, the distance x 161 of the second contact section x 162 to the channel element 116 can be smaller than the distance x 161 of the first contact section 161. The first contact section 161 and the second contact section 162 are each intended to contact a further holding segment, not shown here, or a connection element. In the form shown, the abutment portion 161 has an end face 136 at the end, which in this embodiment shown runs transversely to the longitudinal axis x 160.Furthermore, FIG. 3 shows the legs 111 and 112 from above. The leg 112 has a first side wall 112 aand a second side wall 112 b. The longitudinal axes x 112a and x 112b of these side walls are also the axes of symmetry of the side walls which are offset parallel to one another. With respect to the side walls 111 band 111 a, the offset x 126 is shown to be equal to the wall thickness z 111a. The wall thicknesses z 111a and z 111b may be the same or different. In the example shown, the wall thickness z 111a is greater than the wall thickness of the outer side wall z 111b. Reference character x 111 indicates the length in which both side walls 111a and 111b overlap.The inner side walls 111 aand 112 aeach have a latching element 141 and 142 on the outer side. The reference symbol z 141 shows the axis of symmetry of the latching element 141, which at the same time represents the axis of rotation of a second holding segment connected thereto. Furthermore, in the region of the center in the x direction of the outer side wall 111 b, the axis z 121 is shown, which passes through the center point of the cutout 121, which is not visible in the plan view. On this axis z 121 lies the axis of rotation of two adjacent holding segments after a further holding segment has been connected to this side wall 111 band 112 b.The distance between the center points of the latching element 142 and the recess 122 (not visible) is marked by x 124. In this case, the maximum nominal extent L 111a and L 112b of the respective side walls 111 aand 111 b, or 112 aand 112 b, corresponds to the distance x 124 in the direction of the longitudinal axis.FIG. 4 shows a side view of a further exemplary embodiment of a holding segment 110. This side view shows the leg 112 with the side walls 112 aand 112 b. The side wall 112a has a latching element 142 with a center point M 142. The side wall 112 bhas a cutout 122 corresponding to the latching element 142. This recess has a center M 122. The guide groove 160 has a longitudinal extension of L 160. As seen in the drawing, the length L 160 is equal to the distance x 124 between the centers M 142 and M 122. In addition, the lengths on both sides of the channel element or maximum distances of the contact sections 161 and 162 from the channel element are shown with the reference lines with x 161 and x 162 respectively.The holding segment 110 is divided into the sections Y 110 / 2 (top) and Y 110 / 2 by the bisecting line 115. The illustration shows that the center point M 142 of the latching element 142 or the center point M 122 of the cutout 122 are located in the upper half Y 110 / 2 (top) of the holding segment 110. In the lower half of the holding segment 110, shown as y 110 / 2, is the channel element 116, which extends downward, measured from the lower edge of the leg 112, at most up to a distance y 116( see dashed double arrow). At the lowest point, i.e. at the point of maximum spacing from the leg 112, the guide channel 160 is arranged. The guide groove 160 has a longitudinal extension L 160 which corresponds to the distance between the centers. Other longitudinal extents L 160, which are shorter than the distance between the centres, may be chosen to achieve a slight downward curvature of the receiving channel.In addition, FIG. 4 shows the maximum distance (y Q1-116) of the channel element ( 116) with respect to a rotational axis (Q 1) in the direction of the height axis (y 110) of the holding element ( 110), wherein the rotational axis (Q 1) is aligned with the center points of the respective latching elements ( 141, 142). In the preferred embodiment shown, the distance (Q 1-116) is greater than the height of a leg (y 111,112) and / or the height of one of the first or second side walls (see y 111a / b in FIG. 2 ).The retainer segment 110 may be formed by injection molding. In this way, the holding segment 110 can be produced easily in various complex shapes and in large numbers. The plastic material of the holding segment 110 can be selected from the group of polyamides, polypropylene, polyethylene, polystyrene, acrylonitrile butadiene styrene (ABS); and can preferably have at least sections of the inner side of the guide channel or else on sections of the channel element or of the transverse web a friction-enhancing covering in order to be able to guide or hold the hose or other lines to be accommodated therein better. As an alternative to injection molding, the holding segment can also be produced by 3D printing. The retainer segments can be manufactured according to standards to ensure roundness, parallelism, perpendicularity and symmetry tolerances of castings. As tolerance class, DCTG4, for example, can be adopted as a standard. DCTG4 is suitable for plastic injection molded parts and provides linear dimensional tolerances as well as straightness tolerances of molded parts. For this purpose, it is also possible to prepare the FFS-EN ISO8063-3.FIG. 5 shows a perspective view of an exemplary embodiment of a connection element 210. The connector 210 has a proximal end 250 with a first opening 251 for supporting the connector 210. Said opening 251 may be connected to a support column or another base not shown in FIG. 5 (see e.g. support column 300 in FIG. 7 ). At the opposite distal end 266 is another opening 252 with a rim 267. The distal edge 267 is disposed between the holding ears 211 and 212 and partially surrounds the circular second opening 252.Further, the connector 210 includes a substantially U-shaped reinforcing rib 270 extending from an upper edge 257 of the proximal end 250 to the connector distal end 250.FIG. 6 shows a plan view of the connection element 210 shown in FIG. 4. The connection element 210 extends along the longitudinal axis x 210. The second opening 252 is circular and is configured to receive a first conduit having a diameter less than the circle diameter D 252 of the second opening 252. Furthermore, the holding ears 211, 212 and the rim 267 are also designed for guiding this first line (not shown) to be received.In addition, FIG. 6 shows the transverse axis Q 221-222, which passes through the centers of the recesses 221 and 222 (see FIG. 4 ) of the holding ears 211 and 212. The reinforcing rib 270 extends from the first retaining ear 211 over the proximal end 250 of the connecting element or around parts of the proximal edge of the first opening 251 to the second retaining ear 212. If the latching elements of a retaining segment (not shown here, see FIG. 7 ) are inserted into these recesses 221, 222, this transverse axis Q 212-222 forms an axis of rotation about which the retaining segment can be rotated with respect to the connection element 210. At the proximal end 250, the first opening 251 is shown with a diameter D 251. The diameter D 251 is smaller than the diameter D 252 of the second opening.The distal edge 267 of the circular second opening 252 has a guide groove 260 along the longitudinal axis x 210 of the connection element 210. This guide channel 260 can receive a second line with a smaller diameter than the curvature of the U-profile of the guide channel 260. Reference numeral 263 denotes the distal end surface of the terminal member 210. The distal end face 263 has an abutment portion 265, which, when a further retaining segment 110 is connected to the connection element, can serve as an abutment surface with the associated abutment portion of the retaining segment. The abutment portion 265 is arranged at the height of the guide groove 260.FIG. 7 shows a perspective side view of a receiving channel 200 for at least one line comprising a connection element 210 and two holding segments 110 and 110' connected thereto. FIG. 7 also shows a support column 300, wherein the connection element 210 is mounted rotatably with respect to the support column 300. With the aid of this support column 300, the receiving channel can be rotated through 360°. The contact section 161 of the holding segment 110 abuts the contact surface 265, the end face 263, so that the joined guide channels 160 and 160' of the holding segments 110 and 110' point in an ascending direction. The degree of inclination of the guide channel of the receiving channel 200 can be varied by the selected inclination of the end face 263 or of the contact section 265. Alternatively to a part of the receiving channel facing upwards from the connection element, the end face can run perpendicularly in order to provide a receiving channel running substantially in the horizontal direction.If a line such as a hose and / or cable is or are received in the receiving channel, the part of the receiving channel, which consists of holding elements 110, 110', can rotate supporting column axis 300. The reinforcing rib 270 gives the connection element 210 high stability, so that when a line is guided in the receiving channel and higher forces are produced by tube movements, a target opening location of the receiving channel 200 is provided at the axis of rotation of the recess 221 (see Q 221-222 in FIG. 6 ). In this way, in the case of a predeterminable overload threshold, the part consisting of holding segments 110, 110' can be easily separated from the connection element 210. In this case, the setpoint opening point is between the connection element 210 and the holding element 110.FIG. 8 shows a perspective illustration of a support column 300 having an upper support column section 301 with a first diameter D T1 and a lower support column section 302 with a second diameter D T2, which is greater than the first diameter D T1. In this way, the support column 300 is designed as a telescopic support column which can be extended or enlarged along the axis A as required. For transport, the support column 300 may be downsized and slid into each other such that only the support column portion 302 needs to be stored. In addition, FIG. 8 shows an opening 310 for a locking pin (see also reference sign 311 in FIG. 15 a) which prevents the connection element 210 from being unintentionally removed upwards.FIG. 9 shows a perspective view obliquely from above of a further exemplary embodiment of a holding device 100. The combination of support column 300 and receiving channel 200 form a holding device 100, wherein receiving channel 200 consists of a plurality of holding elements 110, 110' and 110', which, as it were, forms a holding arm, and a connecting element 210. The opening 310 for the locking pin in the support column 300 is, in the position shown, just above the upper edge 257 of the connection element 210. A locking pin (not shown) serving for securing is preferably prestressed with a spring, so that the locking pin automatically protrudes beyond the outer circumference of the first supporting column section 301.If the connecting element 210 with its first opening 251 is guided over the free end of the first support column section 301 as far as the flange 312 of the second support column section 302 with the outer diameter D T2 the locking pin, which is initially pressed inward, can protrude through the opening 310 beyond the edge 257 of the connecting element 210. In this way, the upward sliding out of the terminal element 210 is prevented. The support column portion 301 is thus arranged secured in the first opening 251 of the connection element 210. The receiving channel 200 thus secured can be rotated 360° on the circumferential flange 312 of the support column section 302 about the axis A.In addition to the degree of freedom of movement made possible by the support column 300 in conjunction with the connecting element 210, each holding segment 110' can be rotated or folded upwards or towards the connecting element about an axis of rotation Q. While movements of the holding segments 110, 110' with respect to one another further than up to the stops of the contact sections are not possible, a limited rotation of the holding segments with respect to one another upwards and / or in the direction of the connection element is made possible. That is to say that the receiving channel 200 shown itself has no mobility, or only a very slight mobility, to the side or downwards, but can advantageously be rolled upwards for clearance. This provides a partial flexibility along the longitudinal axis of the receiving channel. This distinguishes the flexible arm of support segments 110, 110' and receiving channel 200 from completely rigid receiving channels, but also from channels that are flexible in all directions (top down, side).FIGS. 10 and 11 show different embodiments of a holding device 100 with differently configured receiving channels 200. The receiving channel 200 of FIG. 10 has an elongated holding arm made of a plurality of holding segments or a receiving channel subsection, which runs linearly upward along the longitudinal axis of the receiving channel 200 or the receiving channel subsection. This straight course 150 corresponds to the use position 620. Reference numeral 151 designates the free or distal end of the receiving channel 200 and reference numeral 250 designates the proximal end of the connecting element or receiving channel. The length x 150 of the receiving channel 200 can be extended by connecting a plurality of holding segments 110 and 110' to a length x 150 of at most 1.50 m. Longer or shorter dimensions of the receiving channel are also conceivable as long as the lines to be received can be held in a stable manner and the receiving channel 200 does not break apart from the distal end at the connection element 210 due to its own weight and leverage.FIG. 11 shows a further exemplary embodiment of a receiving channel 200' in the use position 620, wherein the holding arm or part of the receiving channel comprising holding segments 110 has a line guide which is curved in the direction of gravity, i.e. a curved course 180. In other words, the course 180 is concavely curved in the direction of the channel element or the transverse web side or side of the guide channel 160. This curved course 180 is advantageous in particular in use, since a hose accommodated in the accommodation channel 200' can adapt to the curved course 180. In the transition region at the distal end 151 of the receiving channel 200', the hose (not shown, see reference sign 411 in FIG. 16 ) hangs down in a similar curvature due to the force of gravity, so that the hose course at the distal end 151 is more continuous in the case of a curved receiving channel 200' than in the case of a rectilinear receiving channel (FIG. 10 ).This advantageous curvature 180 can be realized by configuring the guide channel 160 shorter at its one free end than at the other opposite free end. For example, the length of the first contact section 161 of the guide channel 160 and thus the maximum distance of the first contact section 161 from the channel element or transverse web 116 can be smaller than the length of the second contact section 162 of the guide channel 160. In this way, the holding segments 110, 110' can form a curved guide channel 160 and can react more flexibly to movements of the hose which is accommodated and not shown here.FIG. 12 shows a container or tool case 400, which is also known as a Systainer, in order to be able to clean and clear the receiving channel 200 and the support column 300. In FIG. 12, a lower container part 401 is indicated, into which the receiving channel 200 can be stored rolled up (for reference numerals 200 and 300, see also FIG. 14 ).In order to clear up the holding device and to achieve a folded-in position 610 of the receiving channel, the support column 300 is separated from the receiving channel 200 (see the downward arrow), as shown in FIG. 13 b. In particular, FIGS. 13 aand 13 b show how the receiving channel 200 can be transferred from the use position 620 into a so-called folded-in position 610. In this case, the free end 151 of the receiving channel 200 is rolled in in the direction of the connection element 210. This is indicated by the arrow curved to the left. The holding segments 110 are designed such that they can be nested one inside the other and can be nested one inside the other in a space-saving manner. To reach the folded-in position 610, the receiving channel 200 can be pivoted into the folded-in position 620 about transverse axes Q which run in the transverse direction of the receiving channel and are aligned with the center points of the respective recess 121, 122 or 221 or 222.FIG. 14 shows a top view of the lower container part 401 of the toolbox 400 shown in FIG. 12 with a rolled-in and partially nested receiving channel 200. The rollable portion of the receiving duct 200 is formed of a plurality of connected support segments 110 and has been rolled about 1.5 times around the connector 210. In this way, the receiving channel 200 fits into the lower container part 401 of the toolbox 400. Furthermore, the support column 300 and a threaded connecting screw 335 for the support column 300 can also be additionally arranged in the lower container part.FIG. 14 thus shows the receiving channel 200 in a possible folded-in position 610 together with the associated one of the support columns 300. The support column 300 can optionally be emptied in an even more space-saving manner if the first support column section 301 is telescopically inserted into the second support column section. Internal threads are provided in support column 300 and particularly in lower portion 302 that can be connected to a base (not shown) by means of lead screw 335.FIGS. 15 aand 15 b show a support column 300 and a wall holder as base 330. The upper support column portion 301 is located above the circumferential flange 312 which serves to guide the connecting element 210. In addition, the locking pin 311 is shown, which serves to prevent the connection element 210 from sliding out in the direction of the free end of the support column 300. The base 330 has two components arranged at right angles to one another, wherein the vertical component 331 can be fastened to a wall and the horizontal component 332 has a connecting piece 333 for the support column 300.FIG. 16 shows a holding device with a receiving channel 200 for receiving a first hose line 411 with a diameter D s. The connecting element 210 is connected via its first opening 251 to a support column 300 which is fastened to a wall by a base 330 designed as a wall holder. The wall support 330 has been shown in detail in Figure 15a and has the advantage that it can be installed so high that the receiving channel 200 can move over the head of an operator.Also shown in FIG. 16 is a second conduit 412 having a smaller diameter D k. The line 412 serves to supply power to the connectable tool. The line 412 can preferably be used for suctioning away dust particles which can be produced during machining work with the connectable tool.The roll-in part of the receiving channel 200 has a course which is curved in the direction of gravity and which is followed by the received hose. After the hose 411 has exited the receiving channel 200, the hose 411, like the receiving channel, also has a downward-curved course. Depending on the operation and positioning of the tube end, less strong or other curvatures can also occur in the transition region at the distal end 151 of the receiving channel 200. On the proximal side of the holding device, i.e. on the side of the base 330, the tube is guided through the second opening of the connection element and then into the receiving channel.FIG. 17 ashows a further exemplary embodiment of a connection element 210. The connection element 210 also has a first opening 251 for receiving a support column 300, as shown in FIG. 17 d. The connection element 210 further comprises a second opening 252 for receiving a first line, which can be a suction hose, for example. The terminal member 210 differs from the embodiment shown in FIG. 5 or 6, for example, in that the side walls of the second opening are not closed. In addition, the recesses 221 and 222 for the retaining segment to be received are formed as circular depressions or blind holes in the retaining ears 211 and 212. The holding segment 110 or the holding elements can abut with the channel element and the guide channel on an abutment surface 265 of the connection element 210 for a more stable connection. For this purpose, the contact surface simulates the lower contour of the holding segments or elements including the guide channel. In this way, a predetermined breaking point or predetermined opening point 170 is provided between the first proximal holding segment 110 and the second proximal holding segment 110', so that the first proximal holding segment 110 connected to the connection element opens and at the same time remains in the contact surface 265 of the connection element 210.FIG. 17 bshows a toolbox 400 having the lower container part 401 and a base 330 which is designed as a perforated plate. In this case, the base 330 is simultaneously the upper container part 402 of the toolcase 400. The perforated plate has a plurality of holes 403, which are arranged at regular distances from the tool case rim. Each hole 403 is adapted to connect the support column 300 to a respective screw element or coupling screw 335.FIG. 17 cshows a perspective view of the toolbox of FIG. 17 bwith a mobile suction device 420, preferably for dust, in connection with a suction hose 411. On the suction device 420, which serves as a mobile base for a holding device with the aid of the wheels, a plurality of tool cases 400 or systems are arranged. The first line 411 is guided into the holding arm of the receiving channel 200. The height of the base 330 is determined by a tower of tool cases 400. Depending on the number of tool cases 400 or systems, the height of the connection element 210 and thus of the receiving channel 200 can be varied. Due to a high arrangement of the swivel holding arm or receiving channel 200 of the holding device, suction and tool work can be carried out without difficulty, since the hose is no longer in the way. In addition, a cable line and / or power supply can also be guided in the guide channel of the receiving channel. As an alternative to a tower of tool cases 400 as the base, tables with corresponding holes 403 can also be used.Furthermore, the invention and the holding device are designed to be used for guiding at least one line. For this purpose, it is first necessary to form a receiving channel made up of provided holding segments and a connecting element.FIG. 18 schematically shows a flow diagram or the method steps of method 500 for forming a recording channel. First, in the first method step 501, two holding segments are detachably connected by a form-fitting latching connection, wherein the latching elements 141, 142 of the first holding segment 110 are brought into engagement with the corresponding recesses 121', 122' of a second holding segment 110'.Method step 502 comprises adapting the length of the receiving channel as a function of the number of further holding segments 110'.Method step 503 comprises connecting the plurality of holding segments to a connection element by means of latching, preferably by means of latching elements 141, 142 of the first holding segment 110 to corresponding recesses 221, 222 of the connection element.
