Description

The invention relates to a holding segment for detachable connection to at least one further holding segment or to a connecting element, as well as to the connecting element for connecting at least one holding segment to a support column. Furthermore, the invention relates to a receiving channel for at least one line, comprising the connecting element and a plurality of holding segments connected thereto, and to a holding device comprising a base and a connecting element connected to holding segments. Finally, the invention relates to the use of the holding device for guiding at least one first line.

Technological background

Contamination and dust are common in the daily work of tradespeople and in industry. Some applications, when using tools for surface finishing and/or chip removal, can generate dust particles from stone materials or even organic materials such as wood. For hygiene reasons and to avoid health risks such as allergies or asthma, it is important to remove any dust from work areas or common areas. Various state-of-the-art machines have been developed for dust removal. This minimizes the exposure of the people operating the machines.

Mobile extraction modules or industrial dust extractors have been developed to protect the health of craftsmen and ensure hygienic standards.

The industrial dust extractor is typically connected to the tool via a hose, sometimes also connected to an electrical or pneumatic line. These connecting lines are typically routed along the floor, which poses the fundamental problem of collisions with the user, damage to the lines themselves, or even twisting of the lines. Therefore, routing the lines away from the floor is the fundamental goal of the invention.

The cables required for the operation of the tools and extraction modules create obstacles and/or hazards for people in the work environment described above.

The invention is therefore based on the object of further developing holding segments and a connecting element for forming a receiving channel, as well as a holding device for at least one cable, while avoiding the aforementioned disadvantages. The receiving channel and holding device are, in particular, variable in length and prevent unintentional breakage of the receiving channel when a cable is in motion. In particular, the holding device should be able to be securely, firmly, and stably attached to its holding part, the so-called connecting element. Furthermore, the holding device should be easy to disassemble and store in a simple and space-saving manner.

Based on 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 support column.

Depending on the weight, length, and movement of the cable or cables to be accommodated in the receiving channel, deflection of the receiving channel may occur. Excessive forces between the connecting element and the free end of the receiving channel may cause the holding segments of the receiving channel to open, resulting in two holding segments falling apart at any point in the receiving channel. Therefore, a targeted separation of the connection between the connecting element and the attached holding segment would be desirable. Alternatively, a predetermined breaking point or opening point can be provided on the holding elements, causing the holding segment connected to the connecting element to fail.

It is therefore a further object to design the connecting element for several holding segments in such a way that forces acting on the connection point due to leverage forces acting at the distal end of the receiving channel and due to bending loads from the forces acting along the longitudinal axis can be absorbed up to a predetermined load threshold in such a way that in the event of an overload a defined opening is provided on the connecting element, in particular of a holding segment connected to the connecting element. In this way, a controlled interruption of the receiving channel at the level of the connecting 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 occurs to the individual elements. The user can rejoin the channel without tools and fully regains its original function; it is therefore a fully reversible and defined opening function in the event of mechanical overload. This function is possible due to the flexibility of the individual links or The holding segments of the receiving channel are designed in such a way that the now free, non-supported chain of holding segments can flexibly move and the user is always protected.

Description of the invention

Based on the invention, the above-mentioned objects are to be achieved better than with conventional devices and systems.

These objects are achieved with the aid of a holding segment for detachable connection to several additional holding segments to form a receiving channel, a connecting element, and a holding device according to the features of the independent claims. Preferred embodiments of the invention emerge from the subclaims following 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 extending along a longitudinal axis of the holding segment for at least one first line, wherein the holding segment is detachably connectable to at least one further holding segment and/or to a connecting element in order to extend the receiving channel. The holding segment has an upwardly open profile with two legs that 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 offset parallel to the respective second side wall by at least one wall thickness. Furthermore, each first side wall has a respective locking element, and each second side wall has a recess corresponding to the locking element, preferably for receiving a locking element of another retaining segment. The channel element is designed such that the centers formed by the locking elements and/or the locking elements are arranged in the upper half of the upwardly open profile of the retaining segment. In particular, a channel element can be understood as a transverse web that runs transversely to the longitudinal axis of the retaining segment and connects the legs, or as a connecting element.

This has the advantage that no tools are required to assemble the holding segments. Using the locking elements and corresponding recesses, the holding segments can be easily connected to one another to form a receiving channel of different lengths. This means that the length of the receiving channel can be individually extended or shortened to suit specific requirements. Because more than the upper half of the locking elements are arranged in the upper half of the holding segment, and the channel element is therefore at least partially spaced downwards from the side walls, the free ends of the legs can be bent towards one another more easily. Thanks to their easier flexibility, the locking elements can be guided more easily into the respective opposite recesses of the nearest 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 a rotation axis, which is aligned with the centers of the respective locking elements, in the direction of the vertical 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 designed with a downward spacing. Thus, an elastic bending profile part is advantageously provided for the precise locking of the locking elements into the corresponding recesses, preferably of another holding segment.

The design of the holding segment described above results in a bendability and flexibility of the legs, particularly in the upper area, so that two holding segments can be easily joined together or separated again with one hand, i.e. with a simple gripping movement using two or more fingers.

Plastic can be used as a suitable durable, flexible material for the holding segments, whereby 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 such that the legs form obtuse angles between 90° and 180° with the channel element or crosspiece, 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 a cross-web surface inclined on both sides or a surface of the channel element inclined on both sides with an angle greater than 90° to the Legs allow the cable to be easily centered and guided within the receiving channel. The larger the selected obtuse angle, the greater the maximum distance of the channel element or crosspiece from an imaginary flat crosspiece between the opposite lower edges of the legs and/or from the rotation axis, which is aligned with the centers of the respective locking elements, thus making it easier to press the legs together.

According to a further preferred embodiment, the first side walls are arranged in the longitudinal axis on one side of the channel element or the transverse web and the second side walls are arranged in the longitudinal axis on the opposite side of the channel element or 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 center point of the locking element and a center point formed by the recess.

In this way, the retaining segment can form a receiving channel with a plurality of retaining segments, which remains open on one side and allows the insertion of one or two cables. The recesses are preferably designed as circular blind holes or holes. The connection with the corresponding locking elements can thus be easily established and released to form a variably extendable or shortenable receiving channel.

According to a further preferred embodiment, the channel element has at least in sections a guide channel with a lowered area, wherein the guide channel preferably projects over 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 received by the guide groove, which has a smaller second diameter than the first diameter of the first line which is guided between the facing side walls of the holding segments.

According to a further preferred embodiment, the first contact section and a second contact section are arranged at 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 each intended for contact with a further holding segment or the connecting element.

The guide channel thus has contact sections, against whose respective end faces a corresponding end face of a contact section of another holding segment can abut. In this way, a continuous guide channel is formed for receiving a second cable. By providing stop sections, the mobility or pivotability of the holding segments relative to one another 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 one another.

According to a further preferred embodiment, a/the guide channel projects beyond the channel element on both sides and/or the maximum distance of the second contact section to the channel element is less than or equal to the maximum distance of the first contact section to the channel element or to the transverse web.

If a shorter distance or a shorter length of one contact section (in the direction of the longitudinal axis of the holding segment) to the channel element or crossbar is provided compared to the distance or length of the other contact section (in the direction of the longitudinal axis of the holding segment), the receiving channel is curved downwards in the direction of gravity. In other words, the locking elements of adjacent holding elements are further apart from each other than the contact sections or end faces of adjacent holding segments pointing in the same direction. In contrast, a receiving channel in an embodiment with equally long maximum distances between the respective contact sections (in the direction of the longitudinal axis of the holding segment) and the channel element or crossbar has a straight receiving channel or a receiving channel that is not curved in the direction of gravity.

According to a further preferred embodiment, the guide groove and/or the profile of the holding segment has a shape symmetrical to its central longitudinal plane.

The symmetrical shape allows the respective cables to be centered in the receiving channel and optionally in the guide trough, thus optimizing load distribution. This central guidance distributes the weight of the cable guided in the receiving channel evenly on both sides of the central longitudinal plane, so that the receiving channel does not become a side, i.e. does not list towards 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 with a first diameter smaller than the clear minimum distance and the guide channel has a profile in order to accommodate a second line with a second diameter which is smaller than half the first diameter, wherein the profile is preferably designed 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, a power cable can be accommodated in the guide trough and a cable with a much larger circumference, such as a hose for transporting air and/or dust or other media, can be arranged above the guide trough.

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 boundary 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 that restricts the pivoting movement of adjacent retaining segments relative to each other. Depending on the design, only parts of the offset can also serve as a limiting 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 a contact section for a holding segment and two holding ears, each with a recess or a locking element for connecting to a corresponding locking element or recess of the at least one holding segment.

The connecting element can advantageously be used to enable a stable and secure connection to other support systems, such as a stable base. However, it should also be considered that a targeted separation of the connection between the connecting element and the attached support segment is desirable.

The connecting element is therefore designed so that the connection point with the connecting element can accommodate leverage forces up to a predetermined load threshold due to the distal end of the receiving channel. If the load threshold is exceeded, a predetermined opening point is provided on the connecting element. This enables a controlled disintegration of the preferably complete receiving channel at the level of the connecting element, so that the part of the receiving channel formed by the holding segments is retained over its entire length and does not disintegrate uncontrollably into individual holding segments.

When the connector element is connected to a support column, this support column can be connected to a tripod or wall mount, for example. This makes the connector element a universally applicable connector, allowing a single channel consisting of support segments and a connector element to be used for many functions while simultaneously being adaptable to different user requirements.

According to a further preferred embodiment, the first opening is at least partially circular and/or formed by at least a portion of a circular segment in order to support the connecting element rotatably about a support column portion of the support column.

If the first opening is circular, the user can rotate the receiving channel 360° around the support column. The support column is designed or attached in such a way that the receiving channel for a tool's cables can be routed above the user's head, for example. This allows for easy handling of surface finishing tools, with cables connected to the tool no longer getting in the way or obstructing certain movements thanks to the receiving channel. Furthermore, work safety can be increased, as the tradesperson can no longer trip over cables lying on the floor.

According to a further preferred embodiment, a preferably circular second opening is arranged between the first opening and the distal end for the passage of at least one first line. In a further advantageous embodiment, a distal edge of the preferably circular second opening, arranged between the retaining ears, has a guide groove along a longitudinal axis of the connecting element for the second line.

In this way, one or two cables leading from the holding segments into the connecting element can be guided through the second Opening downwards along the support column. This advantageously prevents the at least one cable from accidentally falling out upwards and, furthermore, the holding segments can all be designed identically. Thus, one or more cables can be guided through the second opening of the connection element and then guided further in the distal direction in the receiving channel formed from identical holding segments up to its free end, without the cables having to be guided either upwards or laterally out of the receiving channel. If a guide groove is additionally provided in the distal edge between the holding ears, the guide groove of the receiving channel can be continued continuously for better guidance of a cable, for example.

According to a further preferred embodiment, the connecting element has a reinforcing rib which runs from an upper edge of the proximal end to the distal end of the connecting element.

The reinforcing rib provides greater stability to the connecting element, so that under high loads at the distal end of the receiving channel—i.e., at its free end, which is not connected to the connecting element—a predetermined opening point is defined between the connecting element and the attached retaining segment. The connecting element with the reinforcing rib is easily manufactured by injection molding.

Furthermore, a receiving channel for at least one cable is provided, wherein the receiving channel comprises a connecting element and a plurality of holding segments connected thereto. The length of the receiving channel can be extended by connecting one holding segment to additional holding segments. Furthermore, the receiving channel can be pivoted from a use position to a retracted position about rotation axes extending in the transverse direction of the receiving channel, which axes are aligned with the centers of the respective recesses.

This creates a flexibly extendable and shortenable receiving channel whose holding segments can be pivoted from a stable use position into a retracted position. The receiving channel has a section that can be rolled in toward the connecting element. The individual holding segments can only be pivoted in one direction and toward the next holding segment around their respective rotational axis. The end faces of the guide channel's contact sections, which are in contact in the use position, can move away from each other until they reach the desired retracted position.

According to a further preferred embodiment, the receiving channel in the use position assumes a straight course or a course that is concave on the crossbar 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 rests against the second contact section or the associated end face of the further holding segment.

The crossbar side or guide channel side is the side that is opposite the side walls in the vertical direction. The guide channel side is the closed side of the upwardly open profile of the retaining segment.

The straightness of at least the movable or rollable part of the receiving channel or a curved course can be achieved by providing maximum distances of equal or different lengths between the contact sections of a holding segment and the channel element or crosspiece.

According to a further preferred embodiment, the free end of the receiving channel can be rolled into the folded position in the direction of the connecting element, wherein preferably superimposed holding segments can be nested or nested in the folded position; and/or wherein preferably each holding segment can be pivoted by a maximum of 90° relative to the adjacent connecting element or holding segment.

Because the receiving channel can be rolled up from the free end, it can be stored in a space-saving manner. The ability to nest the holding segments one above the other further saves space. When the adjacent sections of the holding segments no longer touch in the folded position, the rolled-up part of the receiving channel takes on a spiral shape. Depending on the size of the container or the space in which the receiving channel is to be stored, this "snail shape" can be deviated from.

According to a further preferred embodiment, the holding segment and/or the connecting element is made of a plastic material; preferably, at least sections of the guide channel and/or the channel element or crosspiece have a friction-increasing coating or a friction-increasing surface can, especially within the recording channel.

This makes the cables less likely to slip in the receiving channel or guide trough, improving handling when a tool connected to the cables is moved. Thanks to the friction-enhancing surface, the cables cannot slip unexpectedly along the longitudinal axis of the receiving channel or sideways. Another advantage is that no additional functional elements are required to clamp or secure the cable or cables.

According to a further preferred embodiment, a holding device is provided which comprises a support column and a receiving channel, wherein the connecting element is rotatably mounted 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 connecting element; and the connecting element is mounted on a circumferential flange of the support column so as to be rotatable about an axis of the support column.

In this way, the receiving channel can be rotated, preferably by 360°, and the tool cables accommodated therein can be rotated around the support column, allowing the user considerable freedom of movement when handling their tool. The support column can be mounted on a base such as a tripod or on a wall bracket to hold the receiving channel for the one or more cables at a height that minimizes disruption to the operator of the holding device while working with the tool connected to the cables. Disruptive work can be achieved, in particular, if the receiving channel is mounted above the user's head height.

According to a further preferred embodiment, the support column has a locking device, in particular a locking pin, at the end of the upper support column section in order to prevent the connecting 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 connecting screw, wherein the base is selected from a group comprising: a tripod, a perforated plate, a table, a workbench, a tool case with a perforated plate and a wall bracket.

The locking mechanism, in particular the locking pin, is preferably pre-tensioned with a spring so that the locking pin automatically projects beyond the outer circumference of the first support column section and can thus secure the connecting element against slipping out.

The support column can be advantageously combined with various base elements, whereby mobile tool case towers or other units with castors can also be used.

Furthermore, the use of a holding device for guiding at least one first line is disclosed, wherein the first line is guided through the second opening of the connecting element and received in the receiving channel. Furthermore, the at least one 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 one first line.

In the position of use, the receiving channel, which is movable around the support column, cooperates with the movements of a tool connected to the hose, in particular in that the receiving channel can be aligned in the direction of the tool by rotating around 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 treatment and/or chip removal, and is preferably guideable in a/the guide groove of the holding segments or the connecting element.

Detailed description of the characters

Terms such as “left,” “right,” “top,” “bottom,” “front,” “back,” “side,” “height,” “length,” “width,” and the like, as they may be used herein, x-axis, y-axis, or z-axis merely describe reference points or reference lines and do not limit the present invention to a specific orientation or configuration. The x-axis extends in the longitudinal direction of the receiving channel. The height axis or height direction of the holding element is an axis or direction oriented parallel to the side walls and perpendicular to the longitudinal axis of the holding element. 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 center plane of the holding segment is spanned by the x- and y-axes and extends centrally between two side walls opposite in the y-direction. The center plane can also be referred to as the 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 symmetry axis 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 retaining device. The proximal end of the receiving channel refers, for example, to the end of the receiving channel that can be attached to a base, while the distal end of the receiving channel is the opposite free end of the receiving channel that is not connected to the base. Furthermore, the term "exemplary" or "e.g." is used herein to describe an example of a possible embodiment of the To describe the invention. The embodiments illustrated in the drawings merely represent examples of how the devices according to the invention, such as the holding segment, connecting element or holding device and method, can be designed and do not represent a conclusive limitation of the invention.

The illustrations are schematic and not necessarily to scale. Furthermore, they do not show all details, but are limited in part to illustrating the details essential to the invention as well as other features that facilitate the explanation and description of the invention. Identical elements in the different figures are designated by the same reference numerals. For ease of understanding, not all elements in all figures are provided with reference numerals. This means that, for the sake of clarity, only those reference numerals that are necessary for the description of the respective figure are used in the individual figures.

1 shows a front view of an embodiment of a holding segment according to the invention with a profile open at the top. The holding segment is identified by the reference numeral 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 flat transverse web or channel element. Compared to the dash-dotted line z ₁₁₆ , the channel element 116 is spaced downwards. In other words, the channel element 116 is spaced downwards from an imaginary flat channel element or crosspiece and, in the embodiment shown, is also curved downwards in a partial region.

In this embodiment, the downwardly curved region of the channel element 116 is arranged centrally on the central axis of the holding segment 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 has a lowered region relative to the channel element surfaces or transverse web surfaces inclined to the y-axis and adjoining the side walls. The guide channel 160 has a width Z _U that 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 partial region 163 is selected such that the guide channel 160 can accommodate a cable with a radius r _K that 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 in the 1 shown 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. The channel element 116 or the crossbar is, as shown in the 1 shown, at least in sections relative to a flat channel element or crosspiece, which extends exclusively parallel to the z-axis or along the dot-dashed line z ₁₁₆ , spaced downwards in such a way that the centers M ₁₄₁ and M ₁₄₂ of the locking elements 141 and 142 are arranged in the upper half of the upwardly open profile of the holding segment, ie above the bisecting dashed line 115. The channel element 116 is angled with respect to both legs 111, 112 and curved in sections in such a way that a maximum distance of the channel element or crosspiece relative to a flat channel element or crosspiece 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 forms an angle α with respect to the channel element or the crosspiece 116. The legs 111, 112 are arranged parallel to one another at a distance z _110a (see double arrow). The vertical extension y ₁₁₀ (see dashed double arrow y ₁₁₀ ) of the retaining segment 110 runs along the y-axis. The first leg 111 has a height y ₁₁₁ and the second leg 112 has a height y ₁₁₂ , with the leg height being measured in each case on the inside of the open profile. The center point M ₁₄₁ of the locking element 141 is arranged halfway up the leg 111, while the center point M ₁₄₂ of the locking element 142 is located on the opposite outer side of the leg.

2 shows a perspective view of the embodiment of the 1 Each leg 111, 112 has two side walls 111a/b and 112a/b. In the middle of the height y ₁₁₁ or y ₁₁₂ of the respective side wall 111a or 112b, locking elements 141 and 142 are arranged. The reference symbol M ₁₄₂ denotes the center point of the locking element 142 (compare locking element 141 on the side wall 111a with reference symbol M ₁₄₁ in 1 ). Each locking element 141, 142 is suitable for fitting into a corresponding recess 121, 122 of a further holding segment 110' (not shown here) or a connecting element (not shown here; see reference numeral 210 in 5 ) in order to detachably connect to the respective holding segment. The second side wall 112a is an offset 126 (see also double arrow x ₁₂₆ , which indicates the extension of the offset in the x-direction) of at least one wall thickness parallel to the second side wall 112b, in order to enable optimal engagement of the locking element 142 in the corresponding recess 122 of an adjacent holding segment. The extent x ₁₂₆ of the offset 126 is shown in the following 3 shown from above.

2 shows a perspective view of the holding segment. This view shows details of the channel element 116 and the guide channel 160. 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 the holding segment 110 runs. In the embodiment shown, the contact section 161 projects 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 representation of the 2 the center point of the recess 122 was marked with the reference symbol M _121. The center point M ₁₂₁ and the center point M ₁₂₂ of the opposite recess 122 have the axis z ₁₂₁ as their common axis. The center points M ₁₄₁ and M ₁₄₂ of the locking elements 141 and 142 each have an axis z ₁₄₁ and z ₁₄₂ which are aligned with one another. As soon as the locking elements 141, 142 are inserted into the corresponding recesses 121, 122 of a further holding segment or a connecting element (not shown), the axis z ₁₄₁ or the axis z ₁₄₂ forms an axis of rotation. The locking elements 141, 142 are designed with a circular outer diameter to enable the holding segments to be easily rotated relative to one another. The locking elements 141, 142 can also have shapes other than those shown here.

The free ends of the side walls 111a, 111b of the leg 111 are semicircular along the longitudinal axis with a radius r _111a to allow the holding segments to rotate relative to one another. The offset 125 forms a stop step. If another holding segment is locked in place via the locking elements 141 and 142 for connection, the additional holding segment (not shown here) can be rotated up to the vertical stop step or offset 125 on the side of the first leg 111 or up to the stop step or offset 126 on the side of the second leg 112. The stop step or offset 126 has a thickness x ₁₂₆ .

The side walls 111a/b and 112a/b arranged 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 passes through the apex and the axis of symmetry S of the guide channel 160. The stop steps or offsets 125 and 126 are formed by the outer side walls 111b and 112b and have a width of x ₁₂₅ or x _126. Each stop step has a curve at its base to transition to the respective leg 111 or 112. The height of the stop step 126 is therefore slightly less than the height y _112a of the side wall 112.

3 shows a top view of the embodiment according to 1 and 2 The dot-dash line indicates the central axis z ₁ of the channel element 116. The minimum length of the transverse web in the x-direction is indicated by 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 designed to protrude beyond the transverse web 116 on both sides. The second contact section 162 can have the same extent x ₁₆₂ as the extent x ₁₆₁ of the first contact section. 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 bear against a further holding segment (not shown here) or against a connecting element. In the form shown, the contact section 161 has an end face 136 at the end, which in this embodiment shown runs transversely to the longitudinal axis x ₁₆₀ .

Furthermore, the 3 the legs 111 and 112 from above. The leg 112 has a first side wall 112a and a second side wall 112b. 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 each other. With respect to the side walls 111b and 111a, it is shown that the offset x ₁₂₆ is equal to the wall thickness z _111a . The wall thicknesses z _111a and z _111b can 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 . The reference symbol x ₁₁₁ indicates the length by which both side walls 111a and 111b overlap.

The inner side walls 111a and 112a each have a locking element 141 and 142 on the outside. The reference symbol z ₁₄₁ indicates the axis of symmetry of the locking element 141, which also represents the axis of rotation of a second holding segment connected to it. Furthermore, in the center region in the x-direction of the outer side wall 111b, the axis z ₁₂₁ is shown, which runs through the center point of the recess 121, not visible in the plan view. The axis of rotation of two adjacent holding segments lies on this axis z ₁₂₁ after another holding segment has been connected to this side wall 111b and 112b.

The distance between the centers of the locking element 142 and the recess 122 (not visible) is marked with x _124. The maximum nominal extension L _111a and L _112b of the respective side walls 111a and 111b or 112a and 112b correspond to the distance x ₁₂₄ in the direction of the longitudinal axis.

4 shows a side view of a further embodiment of a holding segment 110. This side view shows the leg 112 with the side walls 112a and 112b. The side wall 112a has a locking element 142 with a center point M _142. The side wall 112b has a recess 122 corresponding to the locking element 142. This recess has a center point M ₁₂₂ . The guide channel 160 has a longitudinal extent of L ₁₆₀ . As can be 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 to the channel element are shown with the reference symbols x ₁₆₁ and x ₁₆₂ .

The holding segment 110 is divided by the bisecting dashed line 115 into the sections Y _{110/2 (top)} and Y _110/2 . The illustration shows that the center point M ₁₄₂ of the locking element 142 and the center point M ₁₂₂ of the recess 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, represented as y _110/2 , there is the channel element 116, which extends downwards from the lower edge of the leg 112 up to a maximum distance y ₁₁₆ (see dashed double arrow). The guide channel 160 is arranged at the lowest point, i.e. at the point of maximum spacing from the leg 112. The guide channel 160 has a longitudinal extension L ₁₆₀ that corresponds to the distance between the centers. Other longitudinal extensions L ₁₆₀ that are shorter than the distance between the centers can be selected to achieve a slight downward curvature of the receiving channel.

In addition, 4 the maximum distance (y _Q1-116 ) of the channel element (116) relative to a rotation axis (Q ₁ ) in the direction of the height axis (y ₁₁₀ ) of the holding element (110), wherein the rotation axis (Q ₁ ) is aligned with the centers of the respective locking 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 2 ).

The retaining segment 110 can be manufactured by injection molding. In this way, the retaining segment 110 can be easily manufactured in various complex shapes and in large quantities. The plastic material of the retaining segment 110 can be selected from the group consisting of polyamide, polypropylene, polyethylene, polystyrene, and acrylonitrile butadiene styrene (ABS); and can preferably have a friction-increasing coating on at least sections of the inner side of the guide channel or on sections of the channel element or the crosspiece in order to better guide or hold the hose or other lines accommodated therein. As an alternative to injection molding, the retaining segment can also be manufactured using 3D printing. The retaining segments can be manufactured according to standards to ensure roundness, parallelism, perpendicularity, and symmetry tolerances of cast parts. For example, DCTG4 can be used as a standard tolerance class. DCTG4 is suitable for plastic injection-molded parts and ensures linear dimensional and straightness tolerances of cast parts. FFS-EN ISO8063-3 can also be used for this purpose.

5 shows a perspective view of an embodiment of a connecting element 210. The connecting element 210 has a proximal end 250 with a first opening 251 for supporting the connecting element 210. Said opening 251 can be connected to a support column or other base which is in 5 is not shown (see e.g. support column 300 in 7 ). At the opposite distal end 266, a further opening 252 is arranged with an edge 267. The distal edge 267 is arranged between the holding ears 211 and 212 and partially encloses the circular second opening 252.

Furthermore, the connecting element 210 has a substantially U-shaped reinforcing rib 270 which extends from an upper edge 257 of the proximal end 250 to the distal end 250 of the connecting element.

6 shows a top view of the 4 shown connection element 210. The connection element 210 extends along the longitudinal axis x ₂₁₀ . The second opening 252 is circular and designed to receive a first line with a diameter smaller than the circular diameter D ₂₅₂ of the second opening 252. Furthermore, the retaining ears 211, 212 and the edge 267 are also designed to guide this first line (not shown) to be received.

In addition, 6 the transverse axis Q _221-222 passing through the centers of the recesses 221 and 222 (see 4 ) of the retaining ears 211 and 212. The reinforcing rib 270 runs 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 locking elements of a retaining segment (not shown here, see 7 ), this transverse axis Q _212-222 forms a rotation axis around which the holding segment can be rotated relative to the connecting 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 connecting element 210. This guide groove 260 can accommodate a second line with a smaller diameter than the curvature of the U-profile of the guide groove 260. Reference numeral 263 designates the distal end face of the connecting element 210. The distal end face 263 has a contact section 265, which, when another holding segment 110 is connected to the connecting element, can serve as a stop surface with the associated contact section of the holding segment. The contact section 265 is arranged at the level of the guide groove 260.

7 shows a perspective side view of a receiving channel 200 for at least one line comprising a connecting element 210 and two holding segments 110 and 110' connected thereto. 7 also shows a support column 300, wherein the connecting element 210 is rotatably mounted with respect to the support column 300. With the help of this support column 300, the receiving channel can be rotated by 360°. The contact section 161 of the holding segment 110 rests against the contact surface 265, the end face 263, so that the joined guide grooves 160 and 160' of the holding segments 110 and 110' point in an ascending direction. The degree of inclination of the guide groove of the receiving channel 200 can be varied by the selected inclination of the end face 263 or the contact section 265. As an alternative to a part of the receiving channel pointing upwards from the connecting element, the end face can run vertically in order to provide a receiving channel running essentially in the horizontal direction.

When a line such as a hose and/or cable is or are received in the receiving channel, the part of the receiving channel consisting of holding elements 110, 110' can rotate about the support column axis 300. The reinforcing rib 270 gives the connecting element 210 a high degree of stability, so that when a line is guided in the receiving channel and higher forces arise due to hose movements, a desired opening point of the receiving channel 200 at the rotation axis of the recess 221 (see Q _221-222 in 6 ). In this way, at a predeterminable overload threshold, the part consisting of holding segments 110, 110' can be easily separated from the connecting element 210. The desired opening point is between the connecting element 210 and the holding element 110.

8 shows a perspective view of a support column 300 with 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 that is larger than the first diameter D _T1 . In this way, the support column 300 is designed as a telescopic support column that can be extended or enlarged along the axis A as required. For transport, the support column 300 can be reduced in size and pushed into one another so that only the support column section 302 needs to be stowed. In addition, 8 an opening 310 for a locking pin (see also reference numeral 311 in 15a) which prevents the connecting element 210 from being accidentally removed upwards.

9 shows a perspective view obliquely from above of another embodiment of a holding device 100. The combination of support column 300 and receiving channel 200 form a holding device 100, wherein the receiving channel 200 consists of several holding elements 110, 110' and 110', which form a holding arm, as it were, 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 connecting element 210. A locking pin (not shown) used for securing is preferably preloaded with a spring so that the locking pin automatically projects beyond the outer circumference of the first support column section 301.

If the connecting element 210 with its first opening 251 is connected to the outside via the free end of the first support column section 301 to the flange 312 of the second support column section 302, diameter D _T2 , the locking pin, which is initially pushed inward, can spring out through the opening 310 over the edge 257 of the connecting element 210. In this way, the sliding out of the connecting element 210 upward is prevented. The support column section 301 is thus securely arranged in the first opening 251 of the connecting element 210. The thus secured receiving channel 200 can be rotated 360° about the axis A on the circumferential flange 312 of the support column section 302.

In addition to the degree of freedom of movement enabled by the support column 300 in conjunction with the connecting element 210, each holding segment 110' can be rotated or folded upwards or toward the connecting element about a rotation axis Q. While movements of the holding segments 110, 110' relative to one another are not possible further than the stops of the contact sections, a limited rotation of the holding segments relative to one another upwards and/or toward the connecting element is enabled. This means that the illustrated receiving channel 200 itself has no or only very slight mobility to the side or downwards, but can advantageously be rolled up for storage. This provides partial flexibility along the longitudinal axis of the receiving channel. This distinguishes the flexible arm comprising holding segments 110, 110' and the receiving channel 200 from completely rigid receiving channels, but also from channels that are flexible in all directions (top, bottom, sideways).

10 and 11 show various embodiments of a holding device 100 with differently designed receiving channels 200. The receiving channel 200 of the 10 has an elongated holding arm made up of a plurality of holding segments or a receiving channel section that runs straight upwards along the longitudinal axis of the receiving channel 200 or the receiving channel section. This straight line 150 corresponds to the use position 620. The reference symbol 151 designates the free or distal end of the receiving channel 200, and the reference symbol 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 or 110' up to a length x ₁₅₀ of a maximum of 1.50 m. Longer or shorter dimensions of the receiving channel are also conceivable, as long as the lines to be accommodated can be held stably and the receiving channel 200 does not break apart at the connecting element 210 due to its own weight and leverage from the distal end.

11 shows a further embodiment of a receiving channel 200' in the use position 620, wherein the holding arm or part of the receiving channel made of holding segments 110 has a line 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 crossbar side or side of the guide channel 160. This curved course 180 is particularly advantageous in use, since a hose received in the receiving channel 200' can adapt to the curved course 180. In the transition area at the distal end 151 of the receiving channel 200', the hose hangs (not shown, see reference numeral 411 in 16 ) due to gravity downwards in a similar curvature, so that the tube path at the distal end 151 is more continuous in a curved receiving channel 200' than in a straight receiving channel ( 10 ).

This advantageous curvature 180 can be achieved by making the guide channel 160 shorter at 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 crosspiece 116, can be shorter 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 respond more flexibly to movements of the accommodated hose (not shown here).

12 shows a container or tool case 400, which is also known under the name Systainer, in order to store the receiving channel 200 and the support column 300 neatly and clearly. 12 a lower container part 401 is displayed, in which the receiving channel 200 can be rolled up and stored (for reference numerals 200 and 300 see also 14 ).

To tidy up the holding device and to achieve a folding position 610 of the receiving channel, as shown in 13b shown, the support column 300 is separated from the receiving channel 200 (see downward arrow). In particular, the 13a and 13b how the receiving channel 200 can be transferred from the use position 620 into a so-called folded position 610. In this case, the free end 151 of the receiving channel 200 is rolled in the direction of the connecting element 210. This is indicated by the arrow curved to the left. The holding segments 110 are designed such that they can be nested into one another and can interlock in a space-saving manner. The receiving channel 200 can be folded in the transverse direction of the receiving channel to reach the folded position 610. running transverse axes Q, which are aligned with the centers of the respective recesses 121, 122 or 221 or 222, are pivoted into the folding position 620.

14 shows a top view of the lower container part 401 of the 12 shown tool case 400 with a rolled-up and partially nested receiving channel 200. The movable or rollable part of the receiving channel 200 is formed from a plurality of connected holding segments 110 and was laid or rolled approximately 1.5 times around the connecting element 210. In this way, the receiving channel 200 fits into the lower container part 401 of the tool case 400. Furthermore, the support column 300 and a threaded connecting screw 335 for the support column 300 can also be arranged in the lower container part.

14 thus shows the receiving channel 200 in a possible folded position 610 together with the associated support column 300. The support column 300 can optionally be stored in an even more space-saving manner if the first support column section 301 is telescopically inserted into the second support column section. An internal thread is provided in the support column 300, and in particular in the lower section 302, which can be connected to a base (not shown) by means of the connecting screw 335.

15a and 15b show a support column 300 and a wall mount as a base 330. The upper support column section 301 is located above the circumferential flange 312, which serves to guide the connecting element 210. Also shown is the locking pin 311, which serves to prevent the connecting element 210 from slipping out toward the free end of the support column 300. The base 330 has two components arranged at right angles to each other, wherein the vertical component 331 can be attached to a wall and the horizontal component 332 has a connecting piece 333 for the support column 300.

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 attached to a wall by a base 330 designed as a wall bracket. The wall bracket 330 was 15a shown in detail and has the advantage that it can be installed high enough for the receiving channel 200 to move above the head of an operator.

In addition, 16 A second line 412 with a smaller diameter D _k is shown. Line 412 serves to supply power to the connectable tool. Line 412 can preferably be used to extract dust particles that may arise during machining operations with the connectable tool.

The rollable portion of the receiving channel 200 has a curved path in the direction of gravity, which the received tube follows. After the tube 411 exits the receiving channel 200, the tube 411, like the receiving channel, also has a downwardly curved path. Depending on the operation and positioning of the tube end, less pronounced or different curves may occur in the transition area 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 connecting element and then into the receiving channel.

17a shows a further embodiment of a connecting element 210. The connecting element 210 also has a first opening 251 for receiving a support column 300, as in 17d The connecting element 210 further comprises a second opening 252 for receiving a first line, which may be, for example, a suction hose. The connecting element 210 differs from the openings shown, for example, in 5 or 6 shown embodiment in that the side walls of the second opening are not closed. In addition, the recesses 221 and 222 for the holding segment to be received are designed as circular depressions or blind holes in the holding ears 211 and 212. The holding segment 110 or the holding elements can rest with the groove element and the guide groove on a contact surface 265 of the connecting element 210 for a more stable connection. For this purpose, the contact surface mimics the lower contour of the holding segments or elements, including the guide groove. 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 connecting element opens and at the same time remains in the contact surface 265 of the connecting element 210.

17b shows a tool case 400 with the lower container part 401 and a base 330, which is designed as a perforated plate. The base 330 is simultaneously the upper container part 402 of the tool case 400. The perforated plate has a plurality of holes 403, which are arranged at regular intervals from the tool case edge. Each hole 403 is suitable for supporting column 300 with a corresponding screw element or connecting screw 335.

17c shows a perspective view of the tool case of the 17b with a mobile suction device 420, preferably for dust, in conjunction with a suction hose 411. Several tool cases 400 or Systainers are arranged on the suction device 420, which, with the help of the wheels, serves as a mobile base for a holding device. 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 Systainers, the height of the connecting element 210 and thus of the receiving channel 200 can be varied. By arranging the swivel holding arm or receiving channel 200 of the holding device at a high position, 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 routed in the guide groove of the receiving channel. As an alternative to a tower of tool cases 400 as a base, tables with corresponding holes 403 can also be used.

Furthermore, the invention and the holding device are designed to be used to guide at least one cable. For this purpose, it is first necessary to form a receiving channel from provided holding segments and a connecting element.

18 shows a schematic flowchart or the method steps of the method 500 for forming a receiving channel. First, in the first method step 501, two holding segments are releasably connected by a positive locking connection, wherein the locking 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 includes adjusting the length of the receiving channel depending on the number of additional holding segments 110'.

Method step 503 comprises connecting the plurality of holding segments to a connecting element by snapping them together, preferably by snapping elements 141, 142 of the first holding segment 110 into corresponding recesses 221, 222 of the connecting element. In this way, a receiving channel for one or two lines is provided.

19 shows schematically the method steps of using the receiving channel for at least one line comprising a connection element 210 and a plurality of holding segments connected thereto.

• Einklappstellung 610 und Gebrauchsstellung 620.

A distinction is made here between two positions or modes of use:

• Folding position 610 and use position 620.

To reach the folding position 610, the holding segments are pivoted into a folding position about transverse axes running in the transverse direction of the receiving channel according to step 611.

Method step 612 comprises a substantially spiral folding of the holding segments for space-saving storage in a storage box such as a tool case or Systainer.

To reach the use position 620, according to step 611, the connecting element is mounted on a vertical support column in order to be able to rotate the horizontal or slightly curved receiving channel, preferably 360°. Finally, in step 622, at least one first line and optionally a second line are inserted into the receiving channel; the rotatable receiving channel can follow the movements of the free end of the received first line. This means that in the use position, the receiving channel can cooperate with a tool connected to the hose, thereby optimally and smoothly supporting all tool movements or hose movements.
