Description

[0001] The invention relates to a receiving channel for a suction hose of a suction device and to a suction device equipped therewith or to a machine tool equipped therewith, in particular a semi-stationary machine tool.

[0002] Dust, chips, particles, or the like that arise in connection with the use of, in particular, mobile or semi-stationary machine tools, for example saws, drills, and especially grinders, are generated, for the extraction of which suction devices, for example workshop vacuum cleaners, industrial vacuum cleaners, or the like. The suction device is connected to the machine tool via a line, in particular via a suction hose. In addition to the suction hose, an electrical transmission line can also be provided between the suction device and the machine tool, wherein, for example, control commands can be transmitted from the machine tool to the suction device and / or vice versa via the electrical transmission line.

[0003] Cables running between a suction device and a machine tool, in particular suction hoses, form obstacles that are disruptive in a working environment, particularly when they are located on a floor.

[0004] It is therefore the object of the present invention to provide an improved line guide for a line between a suction device and a machine tool.

[0005] To achieve the object, a receiving channel for a suction hose of a suction device is provided, wherein the receiving channel is formed from a plurality of channel segments pivotally connected to one another by means of pivot bearings, each of which provides a receiving channel section of the receiving channel for receiving the suction hose, wherein the receiving channel section extends along a longitudinal axis of the channel segment, wherein a respective channel segment has a base from which legs protrude, which together with the base delimit the receiving channel section of the respective channel segment, wherein the pivot bearings are formed by connecting elements pivotably engaging one another and arranged on the legs and connecting receptacles of directly adjacent channel segments, wherein the receiving channel is adjustable between a use position and a non-use position,wherein the channel segments have stop surfaces on their sides facing a respective adjacent channel segment, with which the adjacent channel segments abut one another in the use position of the receiving channel, so that the receiving channel assumes an elongated shape suitable for receiving the suction hose in the use position, and wherein channel segments are pivoted towards one another in the non-use position and the stop surfaces of adjacent channel segments are moved away from one another, so that the receiving channel assumes a compact position suitable for transport in the non-use position, in particular a coiled position.

[0006] According to the invention, such a receiving channel can be a component of a suction device or an additional component of a suction device. The suction device has, for example, a support element for supporting the receiving channel. The support element can be formed by a housing of the suction device. The support element can also be a column on the suction device, in particular its housing.

[0007] However, it is also possible for a particularly mobile or semi-stationary machine tool to be equipped with such a receiving channel, e.g. as a component or additional part. For example, a milling machine, sawing machine, in particular a semi-stationary sawing machine, can have a receiving channel according to the invention. The machine tool advantageously has a support element or a support column for supporting the receiving channel. It is also possible for the receiving channel to be arranged directly on a housing of the machine tool, which then has or forms the support element. A semi-stationary machine tool is, for example, a mobile machine tool that is transportable, for example can be taken to a construction site, wherein the machine tool is placed or can be placed on a surface when in use. In the machine tool, the receiving channel orThe respective receiving channel section of a channel segment may also have a smaller receiving cross-section than required for a suction hose. For example, the receiving channel may be designed to accommodate and / or guide an electrical power supply cable of the machine tool.

[0008] The suction device and / or the machine tool preferably have a suction connection for a suction hose, which can be connected to the suction connection and accommodated in the receiving channel.

[0009] The machine tool and / or the suction device are preferably mobile and / or devices that can be taken or transported to a work site or devices that can be guided or guided by hand.

[0010] The invention further provides a channel segment as a component of a receiving channel and / or for forming or extending a receiving channel for a suction hose of a suction device, wherein the receiving channel is formed from a plurality of channel segments pivotally connected to one another by means of pivot bearings, wherein the channel segment has and provides a receiving channel section of the receiving channel for receiving the suction hose, wherein the receiving channel section extends along a longitudinal axis of the channel segment, wherein the channel segment has a base from which legs protrude, which together with the base delimit the receiving channel section of the channel segment, wherein the bearing element has connecting elements and / or connection receptacles arranged on the legs to form two pivot bearings spaced apart from one another with respect to the longitudinal axis,wherein a respective pivot bearing can be formed by pivotably engaging connecting elements and connection receptacles of the channel segment and a channel segment directly adjacent to the channel segment or is formed in the assembled state of the receiving channel, wherein in the assembled state of the receiving channel, the channel segment and at least two further channel segments are pivotally connected so that the receiving channel can be adjusted between a use position and a non-use position, wherein the channel segment has stop surfaces on sides facing a respective adjacent channel segment in the use position, wherein the channel segment abuts one of the stop surfaces and a respective adjacent channel segment abuts one of the stop surfaces in the use position of the receiving channel, so that the receiving channel assumes an elongated shape suitable for receiving the suction hose in the use position,and wherein the channel segment and the further channel segments are pivoted towards each other in the non-use position and the stop surfaces of adjacent channel segments are moved away from each other, so that the receiving channel assumes a compact position suitable for transport in the non-use position, in particular a winding position.

[0011] In conjunction with other channel segments, this channel segment can then form the receiving channel. The channel segment can be detachably connected to the other channel segments, for example, to lengthen or shorten the receiving channel. In the use position, the receiving channel section of this channel segment is aligned with the receiving channel section of at least one adjacent channel segment or positioned relative to the receiving channel section in such a way that the suction hose can be inserted into the receiving channel sections of the adjacent channel segments.

[0012] In the non-use position, the receiving channel can also assume a coiled position or a coiled layer. In the non-use position, layers of the receiving channel can lie on top of one another or be coiled. The receiving channel can, for example, be rolled up or rolled in from the use position to the non-use position.

[0013] A receiving channel according to the invention is thus formed from several channel segments. The receiving channel can also be referred to as a receiving channel device.

[0014] In the use position, the receiving channel may, for example, have a straight or essentially straight shape. In any case, the curvature of the receiving channel is less pronounced in the use position than in the non-use position.

[0015] The elongated shape of the receiving channel can be a straight shape or a slightly curved shape.

[0016] In any case, the suction hose can be inserted into the receiving channel in the use position. Once the use position is reached, the receiving channel is rigid or more rigid in one direction of force acting on the receiving channel by the suction hose inserted into the receiving channel, but pivotable in an opposite direction, for example, it can be wound up or rolled up.

[0017] The basic idea is that the receiving channel has an elongated shape in the use position, so that it can accommodate the suction hose, for example, while bridging obstacles. For example, the receiving channel is attached to a housing of the suction device, in particular by means of a support column or other support element.

[0018] The channel segments are preferably detachable from one another, allowing the receiving channel or receiving channel device to be constructed in different lengths. The receiving channel can therefore be lengthened by adding channel segments or shortened by removing channel segments.

[0019] It is advantageous if the legs of a respective channel segment are held on the base in a flexible manner, away from each other and / or toward each other, so that the connecting elements and connection receptacles of immediately adjacent channel segments can be engaged or disengaged. For example, the legs or the connecting areas between the legs and the base of the channel segment are made of an elastic material, such as an elastic plastic material.

[0020] It is advantageous if the distance between the connecting elements and connection receptacles and the floor of a channel segment is greater than that between the free end regions of the legs facing away from the floor. The large distance between the connecting elements and connection receptacles and the floor of the channel segment facilitates bending or adjusting the legs toward or away from each other in order to disengage a connecting element arranged on such a leg from a connection receptacle of an adjacent channel segment or to disengage a connecting element arranged on such a leg from a connecting element of an adjacent channel segment.

[0021] It is preferred if the connecting elements and the connecting receptacles can be inserted into one another along a plug-in axis. In particular, the aforementioned bending adjustment of the legs of immediately adjacent channel segments away from or toward one another allows the connecting elements and connecting receptacles to be disengaged or engaged. The plug-in axis preferably corresponds to a pivot axis about which the channel segments connected to one another by means of the connecting element and the connecting receptacle are pivotably mounted relative to one another.

[0022] It is advantageously provided that at least one pairing of connecting element and connection receptacle of channel segments directly connected to one another has a locking contour arranged on the connecting element and a locking counter-contour arranged on the connection receptacle, wherein the locking contour is in engagement with the locking counter-contour at least in the position of use, preferably up to a pivot angle of the channel segments of at least 45°, preferably at least 60°, even more preferably at least 70° starting from the position of use, and blocks a release of a connecting element from the connection receptacle along the plug-in axis.Even if, for example, a high load acts on the receiving channel, causing the legs of a respective channel segment to deform, which poses the risk of a connecting element becoming loose or dislodged from a connection receptacle, the locking contour counteracts and blocks the connection of the connecting element from becoming loose. For example, the locking contour and / or the locking counter-contour are designed as bayonet contours.

[0023] It is advantageous if the connection receptacle of the pairing of connecting element and connection receptacle has a through-opening through which the locking contour can be pushed to insert the connecting element into the connection receptacle. The locking contour can advantageously only be pushed through the through-opening in an angular position of the channel segments to be connected or connected to one another that corresponds to an angle of at least 60°, preferably at least 70°, even more preferably at least 80° or 90° away from the position of use.

[0024] Alternatively or in addition to the solution with the passage opening for the locking contour, it can also be provided that the locking contour is elastic and initially yields when the connecting element is pushed through or inserted into the connection receptacle. Upon reaching an end position, it protrudes in front of the connection receptacle and engages with the locking counter-contour. Furthermore, an embodiment is also possible in which the locking contour is achieved by plastic deformation of the connecting element when the connecting element is received in the connection receptacle, for example, due to mechanical and / or thermal influences.

[0025] It is advantageous if at least one leg of a respective channel segment has a recess transverse to the longitudinal axis for receiving a connecting section of a leg of a channel segment directly connected to the channel segment, wherein the channel segments are connected to one another by a connecting element which engages in a connecting receptacle, wherein the connecting element is arranged on one of the recess and connecting section and the connecting receptacle is arranged on the other of the recess and connecting section. Such a recess can be formed, for example, by a step. For example, each leg has side walls that are stepped relative to one another.

[0026] Alternatively, however, it is also possible for the receiving channel or the receiving channel device to have channel segments in which the legs are spaced at different distances from one another transversely to the longitudinal axis. For example, the legs of a first type of channel segment can be arranged closer together, while the legs of a second type of channel segment can be arranged further apart, so that the legs of the first type of channel segment can engage between the legs of the second type of channel segment.

[0027] The stop surfaces of the respective channel segments can be arranged at different positions with respect to the longitudinal axis of a respective channel segment.

[0028] Preferably, one of the stop surfaces of a respective channel segment is arranged at a free longitudinal end region of the channel segment facing an adjacent channel segment. It is conceivable that the other stop surface is arranged at the other longitudinal end region. Thus, for example, stop surfaces can be present at opposite longitudinal end regions of a channel segment.

[0029] It is preferred if at least one of the stop surfaces of a respective channel segment is arranged, with respect to the longitudinal axis, between the longitudinal end regions of the channel segment and / or in an interior space of the channel segment delimited by the base and the side legs. The other of the stop surfaces is preferably arranged at the longitudinal end region of this channel segment.

[0030] An advantageous concept provides that the stop surfaces of the receiving channel, at least one of the stop surfaces of a respective channel segment, extends transversely to the longitudinal axis at the bottom of the channel segment and / or at the legs of the channel segment. It is particularly preferred if the stop surface extends, for example, in a U-shape or V-shape along the bottom and both side legs. This enables a particularly large-area contact or a particularly large-area attachment of adjacent channel segments.

[0031] Preferably, at least one leg, preferably both legs, of a respective channel segment is stepped transversely to the longitudinal axis and / or has a step. Such a step can serve, for example, to allow the legs of adjacent channel segments to engage with each other.

[0032] It is advantageous that one of the stop surfaces of the channel segment is arranged on the step or is formed by the step.

[0033] Essentially, the receiving channel serves to accommodate or accommodate a suction hose. The suction hose can be guided through the receiving channel and supported between the suction device and a machine tool. In some cases, a suction hose also has one or more additional lines, for example, for controlling the suction device via the machine tool, for supplying power to the machine tool via the suction device, or similar.

[0034] An advantageous concept provides for a groove in the floor for a cable, in particular a power cable, running alongside and / or on the suction hose. The receiving cross-section of the groove can be smaller than the receiving cross-section for the suction hose. For example, it is advantageous for the receiving cross-section of the groove intended for receiving the cable to be smaller, preferably at most half the size, of the receiving channel section intended for receiving the suction hose.

[0035] It is preferred if the receiving channel has a substantially continuous contour along the channel segments in the use position. For example, the receiving channel has a continuous and / or gapless receiving contour for the suction hose on at least one side wall, for example, a bottom side of the receiving channel.

[0036] The channel for the additional line, which runs next to the suction hose, also preferably has a continuous and / or gap-free contour in the position of use.

[0037] Advantageously, the receiving channel sections of at least one pair of adjacent channel segments, preferably several or all of the channel segments, directly abut one another in the use position in the region of the base and / or the legs of the channel segments. For example, surfaces on the legs and / or the bases of adjacent channel segments extend seamlessly and / or without a gap from one channel segment to the other channel segment when the receiving channel or the receiving channel device is in the use position.

[0038] A continuous or seamless contour or receiving contour of the receiving channel or groove prevents, for example, the suction hose or the line attached to the suction hose from becoming caught in the receiving channel or groove. Continuous or seamless also means that the receiving channel and / or groove may have narrow recesses or gaps, but these are so small that projections of the line or suction hose, such as ribs on a suction hose, cannot become caught in the narrow recesses or gaps.

[0039] The receiving channel preferably has, at a longitudinal end region, a connecting element with a holding receptacle for a support element, in particular a support column, of the suction device and / or a passage opening for the suction hose. The holding receptacle is preferably a bearing receptacle with which the receiving channel is movably mounted, for example pivotably mounted, on the support element. The support column or the support element can protrude in front of a housing of the suction device. The support column can be received in a plug-in receptacle or other column receptacle in the housing of the suction device. Preferably, the support column or the support element is detachable from the housing of the suction device. The support column is preferably telescopic.

[0040] In the operating position, the support column protrudes upwards in front of the housing of the vacuum cleaner. The intake channel is attached to the support column in the manner of a cantilever.

[0041] The connecting element is designed on one side for coupling a channel segment, i.e. it has on one side connecting elements and / or connection receptacles for coupling a channel segment of the receiving channel and on an opposite side connecting means for connection to the or a support element of the suction device, for example a support column of the suction device.

[0042] For example, the connecting element also has a receiving channel section that corresponds to and / or is aligned with a receiving channel section of a channel segment directly connected to the connecting element. Thus, a suction hose can be received in and / or inserted into the receiving channel sections of the connecting element and the channel segment connected to it.

[0043] The housing of the vacuum cleaner can, for example, have rollers for rolling the vacuum cleaner on a surface.

[0044] The housing of the suction device can also be a stacking housing, with which the suction device can be integrated into a stack of, for example, tool cases or can be stacked on top of a stack of tool cases.

[0045] The through-hole on the connecting element allows the suction hose to be guided along the support element or support column to the suction device. For example, the suction hose can be guided or can be guided along the support element or support column from the housing of the suction device into the receiving channel.

[0046] The invention advantageously provides a suction device with a receiving channel according to the above embodiments and with a support element designed in particular as a support column for supporting the receiving channel.

[0047] According to an independent invention or an advantageous embodiment of the previously explained embodiments and inventions, a duct segment is provided with a receiving duct section extending along a longitudinal axis of the duct segment for at least one first line, wherein the duct segment is detachably connectable to at least one further duct segment and / or to a connecting element in order to extend the receiving duct section. The duct segment has an upwardly open profile with two legs that are connected to a base running transversely to the longitudinal axis of the duct segment, wherein both legs have first side walls and second side walls, preferably projecting beyond the base 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 connecting element, and each second side wall has a connecting receptacle corresponding to the connecting element, preferably for receiving a connecting element of another channel segment. The base is designed such that the centers formed by the connecting elements and / or the connecting elements are arranged in the upper half of the upwardly open profile of the channel segment. In particular, a base can be understood as a transverse web or a connecting section, wherein the transverse web or connecting section runs transversely to the longitudinal axis of the channel segment and connects the legs.

[0048] The channel segment can also be called a holding segment.

[0049] The connecting elements are or include, for example, retaining projections.

[0050] Advantageously, the connecting elements have a cylindrical cross-section or a cylindrical shape.

[0051] Advantageously, the connecting elements are or include bearing elements. The connecting elements can be designed, for example, as shaft bodies.

[0052] A connection receptacle preferably comprises a recess.

[0053] The connection receptacle can, for example, be or include a through-hole. It is also possible for the connection receptacle to be or include a blind hole.

[0054] The connecting receptacles are advantageously bearing receptacles for the movable, in particular pivotable, mounting of the retaining projections. For example, the connecting receptacles are pivot bearing receptacles. When a respective connecting element engages in a connecting receptacle, it is preferably pivotably mounted about an angle transverse to the longitudinal axis of the channel segment relative to the channel segment pivotably coupled to it.

[0055] The connecting elements and the connecting receptacles can, for example, be designed and provided for locking together. For example, in this embodiment, the connecting elements are locking elements, and the connecting receptacles are locking receptacles that are designed and provided for locking with the locking elements or connecting elements.

[0056] This has the advantage that no tools are required to assemble the duct segments. Using the connecting elements and the corresponding connecting receptacles, the duct segments can be easily connected to one another to form a receiving duct of different lengths. This means that the length of the receiving duct can be individually extended or shortened to suit specific requirements. Because more than the upper half of the connecting elements are arranged in the upper half of the duct segment, and the base 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 connecting elements can be guided more easily into the respective opposite connecting receptacles of the nearest duct segment.

[0057] According to a preferred embodiment of the channel segment, it is provided that a maximum distance of the base or transverse web relative to a rotation axis, which is aligned with the centers of the respective connecting elements, in the direction of the vertical axis of the connecting 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 base or transverse web along the central axis of the base, wherein the central axis runs transversely to the longitudinal axis of the channel segment, is longer than the distance between the legs. In this way, the base is designed to be spaced downwards. Thus, an elastic bending profile part is advantageously provided for the precise snapping of the connecting elements into the corresponding connection receptacles, preferably of another channel segment.

[0058] The design of the channel segment described above results in bendability and flexibility of the legs, particularly in the upper area, so that two channel segments can be easily joined together or separated again with one hand, i.e. with a simple gripping movement using two or more fingers.

[0059] Plastic can be used as a suitable durable, flexible material for the channel segments, whereby the plastic is selected from the group of polyamides, polypropylene, polyethylene, polystyrene and acrylonitrile butadiene styrene (ABS).

[0060] According to a further preferred embodiment, the base is connected to the legs such that the legs form obtuse angles between 90° and 180° with the base or crosspiece, wherein the legs are preferably arranged parallel to one another. Furthermore, or alternatively, the base or the lower region of the legs preferably has a first stop section.

[0061] Advantageously, the crosspiece has crosspiece surfaces that are spaced further apart in the area of ​​the legs than at a greater distance from the legs. The crosspiece surfaces are, for example, angled to one another and / or have curves.

[0062] For example, the cross-web surface of the cross-web between the legs can be designed in the manner of a trough or be trough-shaped.

[0063] The cross-web surface can, for example, be V-shaped or U-shaped.

[0064] By using a cross-web surface inclined on both sides or a base surface inclined on both sides at an angle greater than 90° to the legs, the cable can be easily centered and guided in the receiving channel section. The larger the selected obtuse angle, the greater the maximum distance of the base or cross-web from an imaginary flat cross-web between the opposite lower edges of the legs and / or from the rotation axis, which is aligned with the centers of the respective connecting elements, thus facilitating the compression of the legs.

[0065] According to a further preferred embodiment, the first side walls are arranged in the longitudinal axis on one side of the base or the transverse web and the second side walls are arranged in the longitudinal axis on the opposite side of the base 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 channel segment between the center point of the connecting element and a center point formed by the connection receptacle.

[0066] In this way, the duct segment can form a receiving duct with a plurality of duct segments, which remains open on one side and allows the insertion of one or two cables. The connection receptacles are preferably designed as circular blind holes or holes. The connection with the corresponding connecting elements can thus be easily established and released to form a variably extendable or shortenable receiving duct.

[0067] According to a further preferred embodiment, the floor has, at least in sections, a channel section with a recessed area and / or a channel for receiving a cable. Advantageously, the channel section protrudes beyond the floor or the crosspiece on one or both sides in the direction of the longitudinal axis of the connecting element.

[0068] In this way, the channel segment or the receiving channel formed by a plurality of channel segments can receive a second line received by the groove section, which has a smaller second diameter than the first diameter of the first line which is guided between the facing side walls of the channel segments.

[0069] According to a further preferred embodiment, the first stop section and a second stop section are arranged at the ends of the channel section opposite each other in the direction of the longitudinal axis, wherein the first stop section and the second stop section each have a stop surface, in particular an end face, which are each intended for abutment or for bearing against a stop section of another channel segment or the connecting element. For example, the first stop section of the channel segment abuts a second stop section of an immediately adjacent channel segment connected to the channel segment, or the second stop section of the channel segment abuts a first stop section of an immediately adjacent channel segment connected to the channel segment.

[0070] The channel section thus has stop sections, against whose respective stop surfaces, in particular end faces, a corresponding stop surface, in particular end face, of a stop section of another channel segment or of the connecting element can strike or abut. In this way, a continuous channel is formed for receiving a second line. By providing stop sections, the mobility and / or pivotability of the channel segments relative to one another is limited. This has the advantage that the receiving channel formed by a plurality of channel segments is not flexible in all directions and can form a stable channel when the stop sections of the channel segments abut one another.

[0071] According to a further preferred embodiment, one or more of the channel sections protrude above the floor on both sides and / or the maximum distance of the second stop section from the floor is less than or equal to the maximum distance of the first stop section from the floor or from the crosspiece.

[0072] If a shorter distance or a shorter length of one stop section (in the direction of the longitudinal axis of the channel segment) from the floor or crossbar is provided compared to the distance or length of the other stop section (in the direction of the longitudinal axis of the channel segment), the receiving channel is curved downwards in the direction of gravity. In other words, the connecting elements of adjacent connecting elements are further apart from each other than the stop sections or end faces of adjacent channel segments pointing in the same direction. In contrast, a receiving channel in an embodiment with equally long maximum distances of the respective stop sections (in the direction of the longitudinal axis of the channel segment) from the floor or crossbar has a straight receiving channel or a receiving channel that is not curved in the direction of gravity.

[0073] According to a further preferred embodiment, the channel section and / or the profile of the channel segment has a shape symmetrical to its central longitudinal plane.

[0074] The symmetrical shape allows the respective cables to be centered in the receiving channel and / or the receiving channel section, and optionally in the gutter section, thus optimizing load distribution. This central routing distributes the weight of the cable routed in the receiving channel and / or the receiving channel section evenly across both sides of the central longitudinal plane, so that the receiving channel does not tilt to one side when the cable is routed straight, i.e., it does not list against one of the side walls.

[0075] 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 channel section 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.

[0076] In this way, for example, an energy line can be accommodated in the gutter section and a line with a much larger circumference, such as a hose for transporting air and / or dust or other media, can be arranged above the gutter section.

[0077] 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 channel segment connectable to the channel segment.

[0078] 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 channel segments relative to each other. Depending on the design, only parts of the offset can also serve as a limiting surface.

[0079] Furthermore, a connecting element for connecting at least one channel segment to a support column is provided, which comprises: a proximal end with a holding receptacle for holding, in particular pivotally movable bearings, the connecting element on the support column; a distal end with a stop portion for a channel segment and two holding ears, each with a connecting receptacle or a connecting element for connecting to a corresponding connecting element or a corresponding connecting receptacle of the at least one channel segment.

[0080] 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 connected duct segment is desirable.

[0081] 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 channel segments is preserved along its entire length and does not disintegrate uncontrollably into individual channel segments.

[0082] 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 receiving channel consisting of channel segments and a connector element to be used for many functions while also being adaptable to different user requirements.

[0083] According to a further preferred embodiment, the holding receptacle 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.

[0084] If the holding fixture is circular, the user can rotate the holding channel 360° around the support column. The support column is designed or attached in such a way that the holding 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 holding channel. Furthermore, work safety can be increased, as the tradesperson can no longer trip over cables lying on the floor.

[0085] According to a further preferred embodiment, a preferably circular through-opening is arranged between the holding receptacle 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 through-opening, arranged between the holding ears, has a groove section along a longitudinal axis of the connecting element for the second line.

[0086] In this way, one or two cables, which are led from the channel segments into the connecting element, can be guided downwards through the lead-through opening along the support column. This advantageously prevents the at least one cable from accidentally falling out upwards and, furthermore, the channel segments can all be designed identically. Thus, one or more cables can be guided through the lead-through opening of the connecting element and then continued in the distal direction in the receiving channel formed from identical channel segments up to its free end, without the cables having to be led out of the receiving channel either upwards or laterally. If a groove section is additionally provided in the distal edge between the holding ears, the groove section of the receiving channel can be continued continuously for better guidance of a cable, for example.

[0087] 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.

[0088] The reinforcing rib provides the connecting element with greater stability, so that under high loads, a predetermined release point or opening point is defined between the connecting element and the connected channel segment at the distal end of the receiving channel—i.e., at its free end, which is not connected to the connecting element. The connecting element with the reinforcing rib is easily manufactured by injection molding.

[0089] Furthermore, a receiving channel for at least one line is provided, wherein the receiving channel comprises a connecting element and a plurality of channel segments connected to the connecting element. The length of the receiving channel can be extended by connecting one channel segment to additional channel segments. Furthermore, the receiving channel is pivotable from a use position to a non-use position about rotation axes extending in the transverse direction of the receiving channel and aligned with the centers of the respective connection receptacles.

[0090] This creates a flexibly extendable and shortenable receiving channel whose channel segments can be pivoted from a stable use position to a non-use position. The receiving channel has a section that can be rolled in toward the connecting element. The individual channel segments can only be pivoted in one direction and toward the next channel segment around their respective rotational axis. The end faces of the stop sections, which are in contact with the channel section in the use position, can move away from each other until they reach a desired non-use position.

[0091] 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 bottom side and / or curved in the direction of gravity, wherein the first stop section of the channel segment or the end face arranged thereon rests against the second stop section or the associated end face of the further channel segment.

[0092] The cross-web side or channel section side is the side that is opposite the side walls in the vertical direction. The channel section side is the closed side of the upwardly open profile of the channel segment.

[0093] The straightness of at least the movable or rollable part of the receiving channel or a curved course can be achieved by providing equal or different maximum distances of the stop sections of a channel segment to the floor or crossbar.

[0094] According to a further preferred embodiment, the free end of the receiving channel can be rolled in the direction of the connecting element into the non-use position, wherein preferably superimposed channel segments are nestable or nested in the non-use position; and / or wherein preferably each channel segment can be pivoted by a maximum of 90° relative to the adjacent connecting element or channel segment.

[0095] Because the receiving channel can be rolled up from the free end, it can be stored in a space-saving manner. For example, the receiving channel can be rolled up into a coil. When the adjacent stop sections of the channel segments no longer touch when not in use, a rolled-up section of the receiving channel advantageously takes on a spiral shape. Depending on the size of the container or the space in which the receiving channel is to be stored, deviations from this "snail shape" are possible.

[0096] It is advantageous if duct segments interlock with one another in wound layers. For example, the base segment of one duct segment can interlock with the legs of another duct segment. This "nesting" of stacked duct segments can advantageously save space.

[0097] According to a further preferred embodiment, the channel segment and / or the connecting element is made of a plastic material.

[0098] It is advantageous that at least sections of the channel section and / or the base or crosspiece have a friction-increasing or slip-resistant coating or a friction-increasing or slip-resistant surface, in particular within the receiving channel section or the receiving channel. The slip-resistant surface can, for example, be designed in the manner of a rubber coating, have slip-resistant structures or the like. In this way, cables received in the receiving channel or in the channel section slip less easily and improve handling when a tool connected to the cables is moved. With the help of the friction-increasing surface, the cables cannot slip unexpectedly quickly along the longitudinal axis of the receiving channel or sideways. The advantage of this is that no further functional elements are required to clamp or secure the cable or cables.

[0099] 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.

[0100] 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 holding receptacle 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] The support column can be advantageously combined with various base elements, whereby mobile tool case stacks or other units with wheels can also be used.

[0105] Furthermore, the use of a holding device for guiding at least one first line is disclosed, wherein the first line is guided through the through-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.

[0106] 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.

[0107] 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 groove section of the channel segments or the connecting element.

[0110] Terms such as "left," "right," "top," "bottom," "front," "rear," "side," "height," "length," "width," and the like, as 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 connecting element is an axis or direction oriented parallel to the side walls and perpendicular to the longitudinal axis of the connecting 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 channel 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 channel segment extends along the y-axis in the midplane and can also be referred to as the symmetry axis S. The central axis of the base is parallel to the z-axis and extends transversely to the longitudinal axis of the channel segment, which extends parallel to the x-axis.

[0111] The term "proximal" is used to describe the position of an element of the receiving channel or the holding device. For example, the proximal end of the receiving channel refers 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 invention. The embodiments illustrated in the drawings merely represent examples of how the devices according to the invention, such as the channel segment, connecting element, or holding device, and methods, can be configured and do not represent an exhaustive limitation of the invention.

[0112] The illustrations are schematic and not necessarily to scale. Furthermore, they do not show all the 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.

[0113] Fig. 1 shows a front view of an embodiment of a channel segment according to the invention with a profile open at the top. The channel segment is identified by the reference numeral 110. The channel segment 110 has two legs 111 and 112, which are connected to a base 116 or transverse web running transversely to the x-axis or transversely to the longitudinal axis x160 of the channel segment 110. The base 116 thus extends in the direction of the z-axis, wherein the length along the base 116 in the z-direction is longer than the distance z110a (see double arrow) between the legs 111, 112. The dash-dotted line z116 indicates the possible course of a flat transverse web or base. Compared to the dash-dotted line z116, the base 116 is spaced downwards. In other words, the base 116 is spaced downwards from an imaginary flat base or crosspiece and, in the embodiment shown, is also curved downwards in a partial region.

[0114] In this embodiment, the downwardly curved region of the base 116 is arranged centrally on the central axis of the channel segment and is designed as a U-profile. In other words, a channel section 160 is formed on both sides of the axis of symmetry S, which has a lowered region relative to the base surfaces or transverse web surfaces inclined to the y-axis and adjoining the side walls. The channel section 160 has a width ZU that corresponds to twice the rounding radius rU of the U-profile and has a curved partial region 163. The rounding radius rU of the curved partial region 163 is selected such that the channel section 160 can accommodate a line with a radius rK that is smaller than the rounding radius rU of the U-profile. The double radius rU corresponds to a receiving cross-section or diameter DU (DU = 2* rU) and the distance zU, which is in the Fig. 1 shown as a dashed double arrow.

[0115] The maximum height y110 of the channel segment 110 parallel to the y-axis is halved at the height of the dashed line 115. The bottom 116 or the crosspiece is, as shown in the Fig. 1 shown, at least in sections relative to a flat base or crosspiece, which extends exclusively parallel to the z-axis or along the dot-dashed line z116, spaced downwards in such a way that the centers M141 and M142 of the connecting elements 141 and 142 are arranged in the upper half of the upwardly open profile of the channel segment, ie above the bisecting dashed line 115. The base 116 is angled with respect to both legs 111, 112 and curved in sections in such a way that a maximum distance of the base or crosspiece relative to a flat base or crosspiece of at least half the height of a leg (y111, y112) is formed.

[0116] The channel segment 110 has a symmetrical cross-section, and each leg 111, 112 forms an angle α with the base or the crosspiece 116. The legs 111, 112 are arranged parallel to one another at a distance z110a (see double arrow). The vertical extension y110 (see dashed double arrow y110) of the channel segment 110 runs along the y-axis. The first leg 111 has a height y111 and the second leg 112 has a height y112, with the leg height being measured on the inside of the open profile. The center point M141 of the connecting element 141 is located halfway up the leg 111, while the center point M142 of the connecting element 142 is located on the opposite outside of the leg.

[0117] Fig. 2 shows a perspective view of the embodiment of the Fig. 1 Each leg 111, 112 has two side walls 111a / b and 112a / b. Connecting elements 141 and 142 are arranged in the middle of the height y111 or y112 of the respective side wall 111a or 112b. The reference symbol M142 designates the center point of the connecting element 142 (compare connecting element 141 on the side wall 111a with reference symbol M141 in Fig. 1 ). Each connecting element 141, 142 is suitable for fitting into a corresponding connection receptacle 121, 122 of a further channel segment 110' (not shown here) or a connecting element (not shown here; see reference numeral 210 in Fig. 5 ) to engage in order to detachably connect to the respective channel segment. The second side wall 112a is offset by an offset 126 (see also double arrow x126, 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 connecting element 142 in the corresponding connection receptacle 122 of an adjacent channel segment. The extent x126 of the offset 126 is shown in the following Fig. 3 shown from above.

[0118] Fig. 2 shows a perspective view of the channel segment. This view shows details of the base 116 and the channel section 160. The channel section 160 has a first stop 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 channel segment 110 runs. In the embodiment shown, the stop section 161 protrudes beyond the base or the transverse web and extends in the direction of the longitudinal axis x160. The stop section 161 has an end face 136 which, in this embodiment shown, runs transversely to the longitudinal axis x160. Other configurations of the stop section 161 are conceivable. For example, the edge section and thus the stop section of the base or transverse web 116 can be shaped as a bulge.

[0119] In the perspective representation of the Fig. 2 The center point of the connection receptacle 122 was marked with the reference symbol M121. The center point M121 and the center point M122 of the opposite connection receptacle 122 have the axis z121 as their common axis. The center points M141 and M142 of the connecting elements 141 and 142 each have an axes z141 and z142 that are aligned with one another. As soon as the connecting elements 141, 142 are inserted into the corresponding connection receptacles 121, 122 of another channel segment or a connecting element (not shown), the axis z141 or the axis z142 forms an axis of rotation. The connecting elements 141, 142 are designed with a circular outer diameter to allow the channel segments to be easily rotated relative to one another. The connecting elements 141, 142 can also have shapes other than those shown here.

[0120] The free ends of the side walls 111a, 111b of the leg 111 are semicircular along the longitudinal axis with a radius r111a to allow the channel segments to rotate relative to one another. The offset 125 forms a stop step. If another channel segment is snapped into place via the connecting elements 141 and 142 for connection, the additional channel 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 x126.

[0121] The side walls 111a / b and 112a / b arranged on the base 116 each run parallel to the central longitudinal plane of the channel segment. The central longitudinal plane runs through the longitudinal axis x160 and passes through the apex and the axis of symmetry S of the channel section 160. The stop steps or offsets 125 and 126 are formed by the outer side walls 111b and 112b and have a width of x125 or x126. Each stop step has a curvature 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 y112a of the side wall 112.

[0122] Fig. 3 shows a top view of the embodiment according to Fig. 1 and Fig. 2 The dotted line indicates the central axis z1 of the base 116. The minimum length of the crosspiece in the x-direction is indicated by L116 and a dashed double arrow. The first stop section 161 of the channel section 160 extends in the direction of the longitudinal axis x160.

[0123] In the exemplary embodiment shown, the channel section 160 is designed to protrude beyond the transverse web 116 on both sides. The second stop section 162 can have the same extent x162 as the extent x161 of the first stop section. Alternatively, the distance x161 of the second stop section x162 from the floor 116 can be smaller than the distance x161 of the first stop section 161. The first stop section 161 and the second stop section 162 are each intended to stop or bear against another channel segment (not shown here) or against a connecting element. In the form shown, the stop section 161 has an end face 136 at the end, which in this embodiment shown runs transversely to the longitudinal axis x160.

[0124] Furthermore, the Fig. 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 x112a and x112b 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 x126 is equal to the wall thickness z111a. The wall thicknesses z111a and z111b can be the same or different. In the example shown, the wall thickness z111a is greater than the wall thickness of the outer side wall z111b. The reference symbol x111 indicates the length by which both side walls 111a and 111b overlap.

[0125] The inner side walls 111a and 112a each have a connecting element 141 and 142 on the outside. Reference symbol z141 indicates the axis of symmetry of the connecting element 141, which also represents the axis of rotation of a second channel segment connected to it. Furthermore, in the center region in the x-direction of the outer side wall 111b, the axis z121 is shown, which runs through the center point of the connecting receptacle 121, not visible in the plan view. The axis of rotation of two adjacent channel segments lies on this axis z121 after another channel segment has been connected to this side wall 111b and 112b.

[0126] The distance between the centers of the connecting element 142 and the connection receptacle 122 (not visible) is marked with x124. The maximum nominal extension L111a and L112b of the respective side walls 111a and 111b, or 112a and 112b, correspond to the distance x124 in the direction of the longitudinal axis.

[0127] Fig. 4 shows a side view of another embodiment of a channel segment 110. This side view shows the leg 112 with the side walls 112a and 112b. The side wall 112a has a connecting element 142 with a center point M142. The side wall 112b has a connecting receptacle 122 corresponding to the connecting element 142. This connecting receptacle has a center point M122. The channel section 160 has a longitudinal extent of L160. As can be seen in the drawing, the length L160 is equal to the distance x124 between the centers M142 and M122. In addition, the lengths on both sides from the floor or maximum distances of the stop sections 161 and 162 from the floor are shown with the reference symbols x161 and x162.

[0128] The channel segment 110 is divided by the bisecting dashed line 115 into the sections y110 / 2 (top) and y110 / 2. The illustration shows that the center point M142 of the connecting element 142 and the center point M122 of the connecting receptacle 122 are located in the upper half y110 / 2 (top) of the channel segment 110. In the lower half of the channel segment 110, represented as y110 / 2, is the base 116, which extends downwards from the lower edge of the leg 112, measured at most up to a distance y116 (see dashed double arrow). The channel section 160 is arranged at the lowest point, i.e. at the point of maximum distance from the leg 112. The channel section 160 has a longitudinal extent L160, which corresponds to the distance between the center points. Other longitudinal dimensions L160, which are shorter than the distance between the centers, can be selected to achieve a slight downward curvature of the receiving channel.

[0129] In addition, Fig. 4 the maximum distance (yQ1-116) of the base (116) relative to a rotation axis (Q1) in the direction of the height axis (y110) of the connecting element (110), wherein the rotation axis (Q1) is aligned with the centers of the respective connecting elements (141, 142). In the preferred embodiment shown, the distance (Q1-116) 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 y111a / b in Figur 2 ).

[0130] The channel segment 110 can be manufactured using injection molding. In this way, the channel segment 110 can be easily manufactured in various complex shapes and in large quantities. The plastic material of the channel segment 110 can be selected from the group consisting of polyamides, polypropylene, polyethylene, polystyrene, and acrylonitrile butadiene styrene (ABS); and can preferably have a friction-increasing or slip-resistant coating on at least sections of the inner side of the channel section or on sections of the base or crosspiece in order to better guide or hold the hose or other lines accommodated therein. As an alternative to injection molding, the channel segment can also be manufactured using 3D printing. The channel segments can be manufactured according to standards to ensure roundness, parallelism, angularity, 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 tolerances and straightness tolerances of cast parts. FFS-EN ISO8063-3 can also be used for this purpose.

[0131] Fig. 5 shows a perspective view of an embodiment of a connecting element 210. The connecting element 210 has a proximal end 250 with a holding receptacle 251 for supporting the connecting element 210. The holding receptacle 251 can be connected to a support column or other base which is in Fig. 5 is not shown (see e.g. support column 300 in Fig. 7 ). At the opposite distal end 266, a through-opening 252 is arranged with an edge 267. The distal edge 267 is arranged between the retaining ears 211 and 212 and partially encloses the circular through-opening 252.

[0132] 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.

[0133] Fig. 6 shows a top view of the Fig. 4 shown connection element 210. The connection element 210 extends along the longitudinal axis x210. The through-opening 252 is circular and designed to receive a first line with a diameter smaller than the circular diameter D252 of the through-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.

[0134] In addition, Fig. 6 the transverse axis Q221-222 passing through the centers of the connecting supports 221 and 222 (see Fig. 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 retaining receptacle 251 to the second retaining ear 212. If the connecting elements of a channel segment (not shown here, see Fig. 7 ), this transverse axis Q212-222 forms a rotation axis around which the channel segment can be rotated relative to the connecting element 210. The holding receptacle 251 with a diameter D251 is shown at the proximal end 250. The diameter D251 is smaller than the diameter D252 of the through-opening.

[0135] The distal edge 267 of the circular through-opening 252 has a groove section 260 along the longitudinal axis x210 of the connecting element 210. This groove section 260 can accommodate a second line with a smaller diameter than the curvature of the U-profile of the groove section 260. Reference numeral 263 denotes the distal end face of the connecting element 210. The distal end face 263 has a stop section 265, which, when another channel segment 110 is connected to the connecting element, can serve as a stop surface with the associated stop section of the channel segment. The stop section 265 is arranged at the level of the groove section 260.

[0136] Fig. 7 shows a perspective side view of a receiving channel 200 for at least one line comprising a connecting element 210 and two channel segments 110 and 110` connected thereto. Fig. 7 also shows a support element 300a in the form of 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 stop section 161 of the channel segment 110 rests against the stop surface 265, the end face 263, so that the joined channel sections 160 and 160' of the channel segments 110 and 110' point in an ascending direction. The degree of inclination of the channel section of the receiving channel 200 can be varied by the selected inclination of the end face 263 or the stop 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.

[0137] When a line such as a hose and / or cable is or are accommodated in the receiving channel, the part of the receiving channel consisting of connecting 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 connection receptacle 221 (see Q221-222 in Fig. 6 ). In this way, at a predeterminable overload threshold, the part consisting of channel segments 110, 110' can be easily separated from the connecting element 210. The desired opening point is between the connecting element 210 and the connecting element 110.

[0138] Fig. 8 shows a perspective view of a support column 300 with an upper support column section 301 with a first diameter DT1 and a lower support column section 302 with a second diameter DT2, which is larger than the first diameter DT1. 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 can be reduced in size and pushed into one another so that only the support column section 302 needs to be stowed. In addition, Fig. 8 an opening 310 for a locking pin (see also reference numeral 311 in Fig. 15a ), which prevents the connecting element 210 from being accidentally removed upwards.

[0139] Fig. 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 connecting 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.

[0140] If the connecting element 210 with its retaining receptacle 251 is guided over the free end of the first support column section 301 to the flange 312 of the second support column section 302 with the outer diameter DT2, the locking pin, which is initially pressed inward, can spring out through the opening 310 over the edge 257 of the connecting element 210. This prevents the connecting element 210 from sliding out upward. The support column section 301 is thus securely arranged in the retaining receptacle 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.

[0141] In addition to the degree of freedom of movement enabled by the support column 300 in conjunction with the connecting element 210, each channel segment 110' can be rotated or folded upwards or towards the connecting element about a rotation axis Q. While movements of the channel segments 110, 110' relative to one another further than the stops of the stop sections are not possible, a limited rotation of the channel segments relative to one another upwards and / or towards the connecting element is enabled. This means that the receiving channel 200 shown 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 made of channel 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).

[0142] Fig. 10 und Fig. 11 show various embodiments of a holding device 100 with differently designed receiving channels 200. The receiving channel 200 of the Fig. 10 has an elongated holding arm made up of a plurality of channel segments or a receiving channel section, which 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 x150 of the receiving channel 200 can be extended by connecting a plurality of channel segments 110 or 110' up to a maximum length x150 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.

[0143] Fig. 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 channel 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 bottom or the crossbar side or side of the groove section 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 Fig. 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 ( Fig. 10 ).

[0144] This advantageous curvature 180 can be realized by making the channel section 160 shorter at one free end than at the other, opposite free end. For example, the length of the first stop section 161 of the channel section 160, and thus the maximum distance of the first stop section 161 from the floor or crosspiece 116, can be shorter than the length of the second stop section 162 of the channel section 160. In this way, the channel segments 110, 110' can form a curved channel section 160 and respond more flexibly to movements of the accommodated hose (not shown here).

[0145] Fig. 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. Fig. 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 Fig. 14 ).

[0146] To tidy up the holding device and to achieve a non-use position 610, which can also be referred to as a folding position, of the receiving channel, as shown in Fig. 13b shown, the support column 300 is separated from the receiving channel 200 (see downward arrow). In particular, the Fig. 13a und Fig. 13b how the receiving channel 200 can be transferred from the use position 620 to the non-use position 610. 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 channel segments 110 are designed such that they can be nested into one another and can interlock in a space-saving manner. To reach the non-use position 610, the receiving channel 200 can be pivoted into the non-use position 620 about transverse axes Q running in the transverse direction of the receiving channel, which are aligned with the centers of the respective connecting receptacles 121, 122, 221, or 222.

[0147] Fig. 14 shows a top view of the lower container part 401 of the Fig. 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 channel 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.

[0148] Fig. 14 thus shows the receiving channel 200 in a possible non-use 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.

[0149] Fig. 15a und Fig. 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 one another, 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.

[0150] Fig. 16 shows a holding device with a receiving channel 200 for receiving a first line 411, for example a suction hose 411a, with a diameter Ds. The connecting element 210 is connected via its holding receptacle 251 to a support column 300, which is fastened to a wall by a base 330 designed as a wall bracket. The wall bracket 330 was Fig. 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.

[0151] In addition, Fig. 16 a second line 412, for example, an electrical connection cable 412a, with a smaller diameter Dk is shown. The line 412 serves to supply power to the connectable tool W. The line 412 can preferably be used to extract dust particles that may arise during machining operations with the connectable tool.

[0152] For example, the second line 412 is a power supply line for supplying power to the machine tool W

[0153] 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 emerges from 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 through-opening of the connecting element and then into the receiving channel.

[0154] Fig. 17a shows a further embodiment of a connecting element 210. The connecting element 210 also has a holding receptacle 251 for receiving a support column 300, as in Fig. 17d The connecting element 210 further comprises a through-opening 252 for receiving a first line, which may be, for example, a suction hose. The connecting element 210 differs from the Fig. 5 or Fig. 6 shown embodiment in that the side walls of the feedthrough opening are not closed. In addition, the connection receptacles 221 and 222 for the channel segment to be received are designed as circular recesses or blind holes in the retaining ears 211 and 212. The channel segment 110 or the connecting elements can rest with the base and the channel section against a stop surface of the connecting element 210 for a more stable connection. For this purpose, the stop surface 265 imitates the lower contour of the channel segments or elements, including the channel section, or has a contour corresponding to the lower contour of the channel segments, including the channel section.In this way, a predetermined breaking point or predetermined opening point 170 is provided between the first proximal channel segment 110 and the second proximal channel segment 110', so that the first proximal channel segment 110 connected to the connecting element opens and at the same time remains in the stop surface 265 of the connecting element 210.

[0155] Fig. 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 arranged at regular intervals from the edge of the tool case. Each hole 403 is suitable for connecting the support column 300 to a corresponding screw element or connecting screw 335.

[0156] Fig. 17c shows a perspective view of the tool case of the Fig. 17b with a mobile vacuum cleaner 420, preferably for dust, in conjunction with a suction hose 411.

[0157] The suction device 420 has as a first line the suction hose 411, to which a machine tool W, for example a saw, can be connected with a suction connection SAW, for example plugged in, in order to suck up dust that accrues during operation of the machine tool W. The suction hose 411 is arranged, for example, on a suction connection 451 of the suction device 420, for example plugged in

[0158] Furthermore, the suction device 420 has electrical supply contacts 450, for example, a socket into which a plug 412b of an electrical connection cable 412a of the machine tool W can be inserted to supply power to the latter. The electrical connection cable 412a forms a second line 412. Both lines 411 and 412 can be received in the receiving channel 200.

[0159] Several tool cases 400 or Systainer are arranged or can be arranged on the suction device 420, which serves as a mobile base for a holding device with the help of the wheels.

[0160] 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 and / or power supply, for example, line 412, can also be routed in the channel section of the receiving channel.

[0161] As an alternative to a tower of tool boxes 400 as a base, tables with corresponding holes 403 can also be used.

[0162] 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 channel segments and a connecting element.

[0163] Fig. 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 channel segments are releasably connected by a positive locking connection, wherein the connecting elements 141, 142 of the first channel segment 110 are brought into engagement with the corresponding connecting receptacles 121', 122' of a second channel segment 110'.

[0164] Method step 502 comprises adjusting the length of the receiving channel depending on the number of additional channel segments 110`.

[0165] Method step 503 comprises connecting the plurality of channel segments to a connecting element by snapping them together, preferably by means of connecting elements 141, 142 of the first channel segment 110 with corresponding connection receptacles 221, 222 of the connecting element. In this way, a receiving channel for one or two lines is provided.

[0166] Fig. 19 schematically shows the method steps for using the receiving channel for at least one line comprising a connecting element 210 and a plurality of channel segments connected thereto. Two positions or modes of use are distinguished: non-use position 610 and use position 620.

[0167] To reach the non-use position 610, according to step 611, the channel segments are pivoted into a non-use position about transverse axes running in the transverse direction of the receiving channel.

[0168] Method step 612 comprises a substantially spiral folding of the channel segments for space-saving storage in a storage box, such as a tool case or Systainer.

[0169] To reach the use position 620, the connecting element is mounted on a vertical support column according to step 621 in order to be able to rotate the horizontal or slightly curved receiving channel by preferably 360°.

[0170] 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.

[0171] The holding device and / or the suction device of the previously explained embodiments is or are provided with the receiving channel 200. Alternatively, instead of the receiving channel 200, a receiving channel 700 can be used, which can preferably be arranged and / or fastened and / or mounted on the support element 300a, namely the support column 300, using a correspondingly modified connection element, i.e., a connection element adapted to the connection element 210.

[0172] A support element 300b in the manner of support element 300a can also be arranged, for example, on the machine tool W or a semi-stationary machine tool that can be provided instead of the machine tool W. The receiving channel 700 can be arranged on the support element 300b, for example, protruding from the support element 300b in a fixed orientation or being rotatably mounted on the support element 300b. A support element (not shown) in the manner of support element 300b could, for example, protrude upward in front of a saw table of a semi-stationary sawing machine (not shown).

[0173] Although a connecting element for the receiving channel 700 is not shown in detail, it is suitable for connecting or connecting a channel segment 710, for example by means of the connecting elements 737 and / or connecting receptacles 738 explained below, which can be provided in the connecting element not shown.

[0174] The receiving channel 700 is formed by channel segments 710. In contrast to the channel segments 100, the channel segments 710 are geometrically designed somewhat differently, but have connecting elements 737 and connecting receptacles 738, which, similar to the connecting elements 141 and 142 and the connecting receptacles 121 and 122, enable the channel segments 710 to be connected to one another.

[0175] The channel segments 710 are constructed similarly. Each channel segment 710 has legs 711, 712, between which a base 716 extends. The base extends along a longitudinal axis 750 between longitudinal end regions 714 and 715 of a respective channel segment 710. The base 716 has base sections 717, 718, which are connected to one another on their sides facing away from the legs 711, 712.

[0176] The bottom 716 and the legs 711, 712 define a receiving channel section 720 which extends between the longitudinal end regions 714 and 715 of the channel segment 710.

[0177] For example, a receiving channel section 720 is formed by side surfaces 721 on the inner sides of the legs 711 and 712 and a bottom surface 712 on the bottom 716. The bottom surface 722 is provided, for example, on the bottom sections 717, 718.

[0178] A plurality of successively arranged receiving channel sections 720 of channel segments 710 form an elongated receiving channel 700, into which, for example, a line 411, in particular the suction hose 411a, can be inserted. Thus, the receiving channel section 720 is suitable for receiving the line 411 and / or the suction hose 411a. At a point facing away from the base 716, the receiving channel section 720 is open or has an opening through which the suction hose 411a or the line 411 can be inserted into the receiving channel section 720.

[0179] A groove 719 is advantageously formed at the connecting area of ​​the base sections 717, 718. The groove 719 extends along the bottom of the receiving channel section 720. The groove 719 is open toward the receiving channel section 720, so that a line, in particular the line 412, can be inserted into the groove 719.

[0180] The groove 719 is suitable, for example, for receiving the connecting cable 412a. For example, a receiving cross-section of the groove 719 is dimensioned such that an electrical power supply cable, for example, a power supply cable with three wires for a 230V power supply, can be accommodated in the groove 719.

[0181] The legs 711, 712 are stepped and have a step 713.

[0182] The step 713 forms a stop surface 725 on an outer side of the channel segment 710 facing away from the receiving channel section 720, against which a stop surface 724 of a channel segment 710 connected to the channel segment 710 can abut. The stop surface 723 is provided at the longitudinal end region 714, i.e., at the free end region of the channel segment 710. The stop surface 725 of the step 713 is provided approximately longitudinally centrally with respect to the longitudinal axis 750.

[0183] In the use position 720, the stop surfaces 724, 725 can strike each other.

[0184] It is advantageous that the stop surfaces 724 and 725 extend along the bottom 716 or the bottom wall 716, namely along its end face, and also along the legs 711 and 712. This allows adjacent channel segments 710 to abut against one another over a large area in the use position 720.

[0185] When adjacent channel segments 710 abut one another in the use position 620, their receiving channel sections 720 merge seamlessly into one another.

[0186] The aligned transition between side surfaces 721 and bottom surfaces 722 of adjacent channel segments 710 is advantageously achieved, among other things, by the respective channel segment 710 not only having a step 713 on its outer circumference, i.e., on its side facing away from the receiving channel section 720, but also on its inner circumference, i.e., in the region of the receiving channel section 720. A step 727 is provided there. The step 727 is provided between support surfaces of the bottom sections 717, 718, which protrude in front of the bottom surfaces 722. Thus, the support surfaces 728 transition in steps into the bottom surfaces 722 of the receiving channel section 720.

[0187] The support surface 728 has a trough 729 extending from the channel 719, into which another channel segment 710 can engage with its outer region facing away from the receiving channel section 720. The trough 729 and the channel 719 have the same longitudinal extension directions. A step is provided between the trough 729 and the channel 719.

[0188] The legs 711 and 712 have leg sections 730 and 731, which are arranged one behind the other with respect to the longitudinal axis 750 and are stepped relative to one another. Each leg section 730 and 731 forms a leg wall or has a leg wall.

[0189] The outer step 713 and the inner step 727 are formed by the leg sections 730 and 731 of the legs 711 and 712, between which a transition region 732 forming the steps 713, 727 extends.

[0190] On the side facing away from the receiving channel 720, the transition region 732 forms the stop surface 725 or has the stop surface 725.

[0191] Transversely to the longitudinal axis 750, the leg sections 730 are further apart than the leg sections 731. Thus, a channel segment 710, with its leg sections 731, which form a recess 731a opposite the leg sections 730, can engage between the leg sections 730 of an immediately adjacent channel segment 710, which form connecting sections 730a. Pivot bearings 733 are provided between the leg sections 730 and 731 of interconnected channel segments 710, with which the channel segments 710 can be pivoted about a pivot axis 734 between the use position 620 and the non-use position 610.

[0192] The pivot bearings 733 have bearing elements 733a, 733b, which interact to form a respective pivot bearing 733. The pivot bearings 733 comprise, as bearing elements 733a, 733b, for example, bearing projections 735 and bearing receptacles 736, which engage with one another to form a respective pivot bearing 733. The bearing projections 735 project outward, i.e., away from the receiving channel section 720, in front of the leg sections 731 arranged closer together with respect to the longitudinal axis 750, so that they can engage in bearing receptacles 736 of an adjacent channel segment 710, wherein the bearing receptacles 736 are provided on the connecting sections 730, which are spaced further apart transversely to the longitudinal axis 750.

[0193] The bearing projections form connecting elements 737 and the bearing receptacles 736 form connecting receptacles 738 with which adjacent channel segments 710 can be connected to one another.

[0194] Such a connection between the connecting elements 737 and the connecting receptacles 738 is preferably detachable, for example by spreading the legs 711, 712 with the bearing projections 735 or connecting elements 737 towards each other and the legs 711, 712 with the connecting receptacles 738 away from each other, whereby the connecting elements 737 can be disengaged from the connecting receptacles 738. In the opposite direction, the assembly of channel segments 710 is achieved in a similar manner, for example if the legs 711, 712 equipped with the connecting receptacles 738 are spread apart from one another, so that the bearing projections or connecting elements 737 of another channel segment 710 can be brought between the spread apart legs 711, 712 until the bearing projections 735 or connecting elements 737 and the bearing receptacles 736 and connecting receptacles 738 are aligned with one another.Then, so to speak, a plug-in movement of the connecting elements 737 into the connecting receptacles 738 is possible along plug-in axes which correspond to the pivot axes 734.

[0195] Now one can imagine that, for example, by loading the receiving channel 700 with a heavy load, by mechanical stress by an operator or the like, such a connection between adjacent channel segments 710 is easily detachable, ie that the legs 711, 712 of a channel segment 710 are spread apart in such a way that the connecting receptacles 738 come out of engagement with the connecting elements 737 of an adjacent channel segment 710.

[0196] To counteract this problem, locking contours 739 are provided on the connecting elements 737 or bearing projections 735, which, at least in the use position 620, engage with locking counter-contours 740 on the bearing receptacles 736 or connection receptacles 738. The locking contours 739 protrude, for example, radially in front of the bearing projection 735 or the connecting element 737 with respect to the pivot axis 734 or the corresponding plug-in axis, and in the use position 620 engage with the locking contour 740. This can be formed, for example, by a circumferential section of the connection receptacle 738 surrounding the connection receptacle 738.

[0197] In order to be able to insert the connecting elements 737 into the connecting receptacles 738, through-openings 731 are provided on the connecting receptacles 738, through which the locking contours 739 can be inserted into the connecting receptacle 738 when inserted along the plug-in axis or pivot axis 734.

[0198] However, this is only possible in predetermined pivoting positions of the channel segments 710 to be connected or detached from one another, which in Figur 23 is shown as an example.

[0199] For example, a channel segment 710a, which is shown in dashed lines, is pivoted by approximately 90° about the pivot axis 734 relative to the other channel segment 710b so that its through-opening 741 is aligned with the locking contour 739 of the other channel segment 710b and the plug-in movement along the pivot axis or plug-in axis 734 is possible. The channel segments 710a and 710b are pivoted, for example, by approximately 80 to 90° with respect to the pivot axis 734 so that the locking contour 739 can be inserted through the through-opening 741. Such a pivot position is fundamentally possible in the non-use position 610, i.e., compact storage of the receiving channel 710 is possible in this way. However, the receiving channel 700 is usually wound in smaller radii, where the channel segments 710 are less deflected against each other than in the Figur 23 illustrated assembly position M, in which the locking contour 739 can be pushed through the passage opening 741.

[0200] Advantageously, it is provided that in the non-use position 610 corresponding pivot positions of adjacent channel segments 710, the locking contour 739 and the locking counter-contour 740 are engaged. This is exemplified in Figur 25 recognizable.

[0201] Examples include Figur 24 The channel segments 710a and 710b are shown in the use position 620, in which the stop surfaces 724, 725 abut each other. It can also be seen that the locking contour 739 is in engagement with the locking counter contour 740.

[0202] Advantageously, it can be provided that a bevel is arranged on the locking contour 739 and / or the locking counter-contour 740, exemplified by a bevel 742 on the locking counter-contour 740. The bevel 742 has a slope rising from the passage opening 741, with a flatter region of the bevel 742 adjacent to the passage opening 741 and rising away from it. Thus, when, starting from the assembly position M, one channel segment 700a is pivoted about the pivot axis 734 in the direction of the use position 620, the locking contour 739 slides along the bevel 742. The bevel 742 and the locking counter-contour 740 on the one hand, and the locking contour 739 on the other, can be designed, for example, in the manner of bayonet contours.
