Definitions
- the subject matter of the invention relates to a line guiding arrangement for running at least one energy line.
- Lines that lead from a stationary terminal to a movable consumer are laid in line guiding arrangements.
- the line guiding arrangement connects with its one end to a fixed point and with its other end to the movable consumer.
- Known are line guiding arrangements that are constructed from flexibly interconnected chain links, which define a receiving chamber.
- the receiving chambers of individual chain links form a channel, in which the lines are laid.
- Two opposite, spaced-apart chain sidebars as well as an upper and a lower crossbar define the receiving chamber.
- the crossbars are connected to the chain sidebars.
- DD 265 449 B5 discloses a line guiding arrangement that comprises a line receiving channel, which is defined by a support wall portion, a cover portion, and side wall portions.
- the line receiving channel is subdivided by transverse separations into a plurality of segments that are tiltable relative to one another.
- the transverse separations extend through the cover portion and continue in the side wall portions to at least the vicinity of the support wall portion.
- EP 0 544 027 B1 discloses a further embodiment of a line guiding arrangement of the described type.
- the line guiding arrangement proposed in EP 0 544 027 B1 serves to guide at least one line that runs in the line receiving channel.
- the line receiving channel comprises a support wall portion, a cover portion, and side wall portions. Transverse separations subdivide the line receiving channel into a plurality of segments that are tiltable relative to one another, so that the line guiding arrangement is bendable while forming a first half and a second half extending parallel thereto, as well as a looplike transition between the two halves.
- the transverse separations extend through the cover portion and continue in the side wall portions to at least the vicinity of the support wall portion.
- At least one of these portions is shaped to project and made flexibly resilient relative to a channel wall portion that supports it toward the interior of the channel.
- the transverse separations extend substantially perpendicularly to the longitudinal direction of the line guiding arrangement.
- Utility Model G 90 16 870.4 discloses a further configuration of a line guiding arrangement.
- the line guiding arrangement as disclosed in this document comprises a line guiding channel and an arrangement of several lines extending therein.
- the line guiding arrangement comprises a lower half and an upper half extending thereabove, which merge into each other in the form of a loop at one end of the guiding arrangement.
- a free end of the lower half connects to a stationary device, and a free end of the upper half to a device moving back and forth in the longitudinal direction of the line guiding arrangement.
- the lines are held together by a common bundling device, the outside of which mounts a sliding device with a good sliding ability that is effective in the longitudinal direction of the line.
- the sliding device prevents friction between the line arrangement portions of the upper half and the lower half even at a great line length.
- Line guiding arrangements as disclosed in DD 265 449 B5, EP 0 544 027 B1, or EP 0 490 022 A2, are made by extruding a profile of a plastic, and subsequently cutting same by means of a suitable tool, so that the channel is subdivided into individual segments.
- Line guiding arrangements as disclosed, for example, in EP 0 544 207 B1, are problematic in that the line guiding arrangement exhibits relatively little flexural and torsional stiffness, so that the practical usability of the line guiding arrangement is relatively limited.
- a further problem with the known line guiding arrangements is that they require additional elements, so-called radius clips, for forming a defined radius of curvature in the loop region. When these elements are connected to the line guiding arrangement, the upper half thereof will no longer be able to slide along the lower half of the line guiding arrangement. This also limits the uses of the line guiding arrangement, since it is not usable for longer distances.
- the object of the present invention to improve the known line guiding arrangement so as to increase the usability of the line guiding arrangement.
- the line guiding arrangement is to exhibit a greater flexural and torsional stiffness.
- a further object of the invention is to provide a line guiding arrangement that facilitates forming a defined radius of curvature even without additional elements.
- a line guiding arrangement which comprises a line receiving channel of generally rectangular outline and which has a base wall portion, a cover portion, and opposite side wall portions.
- the line receiving channel is subdivided by transverse separations into a plurality of segments that are tiltable relative to one another.
- the transverse separations extend through the cover portion, and they continue into the side wall portions to at least the vicinity of the base wall portion.
- At least one transverse separation of two adjacent segments is designed and constructed such that the one segment comprises at least one recess and the other segment a projection which engages within the recess.
- a further aspect of the invention relates to a line guiding arrangement which comprises two substantially parallel channels, which are interconnected by cross members.
- Each channel comprises a base wall portion, a cover portion, and at least one side wall portion.
- Each channel is subdivided by transverse separations into a plurality of segments that are tiltable relative to one another. The transverse separations extend through the cover portion, and they continue to at least the vicinity of the base wall portion. At least one transverse separation of two adjacent segments is designed such that the one segment comprises at least one recess and the other segment a projection engaging in the recess.
- the line guiding arrangements designed and constructed in accordance with the invention are based on the concept that adjacent segments support each other in the longitudinal and/or transverse directions by a suitable configuration of the transverse separations, thereby realizing a higher flexural and torsional strength or transverse stiffness of the line guiding arrangements. If the projection of the one segment extends into the recess of the adjacent segment, a connection between the adjacent segments will be realized, which prevents the adjacent segments from displacing relative to each other. Preferably, the recess and the projection are formed such that adjacent segments remain engaged, even when they are tilted relative to each other in the loop region of the line guiding arrangement. This has the advantage that an increased flexural and torsional strength is realized even in the loop region of the line guiding arrangement.
- the transverse separations may be formed by correspondingly guiding a cutting tool. It is also possible to cut transverse separations into the line guiding arrangement by means of a water jet cutting tool. It is further possible to cut transverse separations into the line guiding arrangement by means of appropriately shaped punch knives.
- the transverse separations have at least one section that intersects the longitudinal axis of the line guiding arrangement at an angle that is not a right angle.
- the transverse separations may be arcuate, so as to describe the arc of a pitch circle.
- the arcuate transverse separations form in the one segment a recess, which has a curved front surface.
- the other segment includes a projection that has a correspondingly curved front surface.
- the transverse separations may also be zigzagged or meander-shaped.
- the recess and the projection in the side wall portions.
- This configuration of the recess and the projection provides in addition a guidance of adjacent segments during a tilting operation. Such a tilting operation occurs during the movement of the line guiding arrangement, when a line section merges into the loop-shaped region of the line guiding arrangement.
- the base wall portion between the cover portion and a bottom portion. Additional transverse separations are provided, which extend through the bottom portion and continue in at least one side wall portion to at least the vicinity of the base wall portion.
- the additional transverse separation of two adjacent segments is formed such that the one segment includes at least one recess and the other segment at least one projection engaging the recess.
- a further advantage of the configuration is provided in the case of transverse separations in the side wall portions below the base wall portion of inverted V-shaped configuration, by which limiters of the arc of curvature are formed, so that additional elements can be omitted. Since the limiters of the arc of curvature form an integral part of the line guiding channel or of each channel, it is possible to run an upper half of the line guiding arrangement on a lower half thereof. Therefore, the line guiding arrangement is also able to overcome greater displacements.
- the projection is composed of a tab having a head that laterally extends beyond the tab cross section.
- the recess comprises a section, in which the tab is movable and a receptacle for the head, in which the head is movable.
- the longitudinal extent of the head receptacle is greater than the longitudinal extent of the head.
- This configuration of the line guiding arrangement accomplishes with simple means a limitation of the angle of tilt of adjacent segments.
- the longitudinal extent of the recess is greater than the longitudinal extent of the projection.
- the recess and the projection are made substantially T-shaped.

- FIG. 1 illustrates a longitudinally extending line guiding arrangement for running at least one energy line.
- the one energy line which is not shown in FIG. 1, runs in a channel 8 of a line receiving channel 1 , which comprises a base wall portion 2 , a cover portion 3 , and side wall portions 4 , 5 .

- the segments 9 , 10 comprise both recesses 11 and projections 12 .
- the segment 9 comprises projections 12 , which engage correspondingly shaped recesses 11 of segment 10 arranged to the left of segment 9 .
- This configuration of the line guiding arrangement has the advantage that the guidance of a cutting tool, which may be, for example, a laser, is always the same.
- the transverse separations may also be selected such that the one segment has only recesses or only projections and the adjacent segment only projections or recesses. Which segments have recesses and/or projections depends on the extension of the transverse separations.
- FIG. 3 is a cutout view of two adjacent segments 9 , 10 in a tilted state. Indicated at a is the angle of tilt of adjacent segments.
- the projection 12 moves out of recess 11 .
- the projection 12 has the shape of a rectangular tab.

- This configuration of the recess 11 and projection 12 has the advantage that even in the tilted state of the segments, the line receiving channel exhibits a greater torsional stiffness. Therefore, it is preferred to select the length of the projection or recess in the longitudinal direction of the line guiding arrangement such that the projection 12 extends in part into the recess 11 even in the tilted state of adjacent segments. This advantage is realized not only with the configuration of recess 11 and projection 12 in the cover portion, but also in the side wall portions.

Abstract
Description
- The present application is a continuation of copending international application PCT/EP89/05810, filed Aug. 10, 1999, and designating the U.S.
- The subject matter of the invention relates to a line guiding arrangement for running at least one energy line.
- Lines that lead from a stationary terminal to a movable consumer are laid in line guiding arrangements. The line guiding arrangement connects with its one end to a fixed point and with its other end to the movable consumer. Known are line guiding arrangements that are constructed from flexibly interconnected chain links, which define a receiving chamber. The receiving chambers of individual chain links form a channel, in which the lines are laid. Two opposite, spaced-apart chain sidebars as well as an upper and a lower crossbar define the receiving chamber. The crossbars are connected to the chain sidebars.
- To run lines, DD 265 449 B5 discloses a line guiding arrangement that comprises a line receiving channel, which is defined by a support wall portion, a cover portion, and side wall portions. The line receiving channel is subdivided by transverse separations into a plurality of segments that are tiltable relative to one another. The transverse separations extend through the cover portion and continue in the side wall portions to at least the vicinity of the support wall portion.
- EP 0 544 027 B1 discloses a further embodiment of a line guiding arrangement of the described type. Likewise, the line guiding arrangement proposed in EP 0 544 027 B1 serves to guide at least one line that runs in the line receiving channel. The line receiving channel comprises a support wall portion, a cover portion, and side wall portions. Transverse separations subdivide the line receiving channel into a plurality of segments that are tiltable relative to one another, so that the line guiding arrangement is bendable while forming a first half and a second half extending parallel thereto, as well as a looplike transition between the two halves. The transverse separations extend through the cover portion and continue in the side wall portions to at least the vicinity of the support wall portion. In the configuration of the line guiding arrangement according to EP 0 544 027 B1, of the cover portion and the side wall portions of the or each line receiving channel, at least one of these portions is shaped to project and made flexibly resilient relative to a channel wall portion that supports it toward the interior of the channel. The transverse separations extend substantially perpendicularly to the longitudinal direction of the line guiding arrangement.
- Utility Model G 90 16 870.4 discloses a further configuration of a line guiding arrangement. The line guiding arrangement as disclosed in this document comprises a line guiding channel and an arrangement of several lines extending therein. The line guiding arrangement comprises a lower half and an upper half extending thereabove, which merge into each other in the form of a loop at one end of the guiding arrangement. A free end of the lower half connects to a stationary device, and a free end of the upper half to a device moving back and forth in the longitudinal direction of the line guiding arrangement. The lines are held together by a common bundling device, the outside of which mounts a sliding device with a good sliding ability that is effective in the longitudinal direction of the line. The sliding device prevents friction between the line arrangement portions of the upper half and the lower half even at a great line length.
- Line guiding arrangements, as disclosed in DD 265 449 B5, EP 0 544 027 B1, or EP 0 490 022 A2, are made by extruding a profile of a plastic, and subsequently cutting same by means of a suitable tool, so that the channel is subdivided into individual segments.
- Line guiding arrangements, as disclosed, for example, in EP 0 544 207 B1, are problematic in that the line guiding arrangement exhibits relatively little flexural and torsional stiffness, so that the practical usability of the line guiding arrangement is relatively limited. A further problem with the known line guiding arrangements is that they require additional elements, so-called radius clips, for forming a defined radius of curvature in the loop region. When these elements are connected to the line guiding arrangement, the upper half thereof will no longer be able to slide along the lower half of the line guiding arrangement. This also limits the uses of the line guiding arrangement, since it is not usable for longer distances.
- Based on the foregoing, it is the object of the present invention to improve the known line guiding arrangement so as to increase the usability of the line guiding arrangement. In particular, the line guiding arrangement is to exhibit a greater flexural and torsional stiffness.
- A further object of the invention is to provide a line guiding arrangement that facilitates forming a defined radius of curvature even without additional elements.
- The above and other objects and advantages of the invention are achieved by the provision of a line guiding arrangement which comprises a line receiving channel of generally rectangular outline and which has a base wall portion, a cover portion, and opposite side wall portions. The line receiving channel is subdivided by transverse separations into a plurality of segments that are tiltable relative to one another. The transverse separations extend through the cover portion, and they continue into the side wall portions to at least the vicinity of the base wall portion. At least one transverse separation of two adjacent segments is designed and constructed such that the one segment comprises at least one recess and the other segment a projection which engages within the recess.
- A further aspect of the invention relates to a line guiding arrangement which comprises two substantially parallel channels, which are interconnected by cross members. Each channel comprises a base wall portion, a cover portion, and at least one side wall portion. Each channel is subdivided by transverse separations into a plurality of segments that are tiltable relative to one another. The transverse separations extend through the cover portion, and they continue to at least the vicinity of the base wall portion. At least one transverse separation of two adjacent segments is designed such that the one segment comprises at least one recess and the other segment a projection engaging in the recess.
- The line guiding arrangements designed and constructed in accordance with the invention are based on the concept that adjacent segments support each other in the longitudinal and/or transverse directions by a suitable configuration of the transverse separations, thereby realizing a higher flexural and torsional strength or transverse stiffness of the line guiding arrangements. If the projection of the one segment extends into the recess of the adjacent segment, a connection between the adjacent segments will be realized, which prevents the adjacent segments from displacing relative to each other. Preferably, the recess and the projection are formed such that adjacent segments remain engaged, even when they are tilted relative to each other in the loop region of the line guiding arrangement. This has the advantage that an increased flexural and torsional strength is realized even in the loop region of the line guiding arrangement.
- The transverse separations may be formed by correspondingly guiding a cutting tool. It is also possible to cut transverse separations into the line guiding arrangement by means of a water jet cutting tool. It is further possible to cut transverse separations into the line guiding arrangement by means of appropriately shaped punch knives.
- Preferably, the transverse separations have at least one section that intersects the longitudinal axis of the line guiding arrangement at an angle that is not a right angle. For example, the transverse separations may be arcuate, so as to describe the arc of a pitch circle. The arcuate transverse separations form in the one segment a recess, which has a curved front surface. The other segment includes a projection that has a correspondingly curved front surface. The transverse separations may also be zigzagged or meander-shaped.
- According to an advantageous further development of the line guiding arrangements of the present invention, it is proposed to form the recess and the projection in the side wall portions. In particular, it is proposed to provide the recess and the projection with at least one arcuate section that extends in the longitudinal direction of the line guiding arrangement. This configuration of the recess and the projection provides in addition a guidance of adjacent segments during a tilting operation. Such a tilting operation occurs during the movement of the line guiding arrangement, when a line section merges into the loop-shaped region of the line guiding arrangement.
- According to a further, advantageous configuration of the line guiding arrangement in accordance with the invention, it is proposed to form the recess and projection in cover wall portions. The formation of projections and recesses in the cover wall portions entail an increased flexural and torsional strength of the line guiding arrangement.
- According to a still further, advantageous configuration of the line guiding arrangement, it is proposed to form the base wall portion between the cover portion and a bottom portion. Additional transverse separations are provided, which extend through the bottom portion and continue in at least one side wall portion to at least the vicinity of the base wall portion. The additional transverse separation of two adjacent segments is formed such that the one segment includes at least one recess and the other segment at least one projection engaging the recess. The recess resulting from this additional measure that is taken in a line guiding arrangement, permits a still higher flexural and torsional stiffness of the line guiding arrangement to be achieved. A further advantage of the configuration is provided in the case of transverse separations in the side wall portions below the base wall portion of inverted V-shaped configuration, by which limiters of the arc of curvature are formed, so that additional elements can be omitted. Since the limiters of the arc of curvature form an integral part of the line guiding channel or of each channel, it is possible to run an upper half of the line guiding arrangement on a lower half thereof. Therefore, the line guiding arrangement is also able to overcome greater displacements.
- According to a still further, advantageous configuration, it is proposed to make the recess and projection such that they complement each other. This simplifies production of the line guiding arrangement.
- The limitation of the angle of tilt and thus likewise of the arc of curvature of the line guiding arrangement in the region of the loop formation may also occur in that the recess and the projection have each at least one stop surface that limits an angle of arc of adjacent segments.
- According to a still further, advantageous embodiment of the line guiding arrangement, it is proposed to form the projection so that it is composed of a tab having a head that laterally extends beyond the tab cross section. The recess comprises a section, in which the tab is movable and a receptacle for the head, in which the head is movable. The longitudinal extent of the head receptacle is greater than the longitudinal extent of the head. This can be realized by corresponding punchings or cutouts. This configuration of the line guiding arrangement accomplishes with simple means a limitation of the angle of tilt of adjacent segments. In particular, the longitudinal extent of the recess is greater than the longitudinal extent of the projection. Preferably, the recess and the projection are made substantially T-shaped.

- FIG. 1 illustrates a longitudinally extending line guiding arrangement for running at least one energy line. The one energy line, which is not shown in FIG. 1, runs in a
channel 8 of a line receiving channel 1, which comprises abase wall portion 2, acover portion 3, andside wall portions -
Transverse separations 6 subdivide the line receiving channel 1 into a plurality ofsegments transverse separations 6 extend through thecover portion 3, and they continue inside wall portions base wall portion 2. In the illustrated embodiment, thetransverse separations 6 terminate inopenings 7, which have a substantially circular cross section. Thecircular openings 7 are intended to reduce material stress of the line receiving channel 1 in the tilted state ofadjacent segments - The
transverse separations 6 of twoadjacent segments segment 9 has at least onerecess 11, and theother segment 10 has at least oneprojection 12 engaging therecess 11. In the illustrated embodiment, thesegments recesses 11 andprojections 12. For example, if one looks atsegment 9, it comprises recesses 11 towardsegment 10 that adjoinssegment 9 to the right, into whichprojections 12 ofadjacent segment 10 to the right ofsegment 9 extend. In the edge region opposite torecesses 11, thesegment 9 comprisesprojections 12, which engage correspondingly shapedrecesses 11 ofsegment 10 arranged to the left ofsegment 9. This configuration of the line guiding arrangement has the advantage that the guidance of a cutting tool, which may be, for example, a laser, is always the same. To the extent that it is useful, the transverse separations may also be selected such that the one segment has only recesses or only projections and the adjacent segment only projections or recesses. Which segments have recesses and/or projections depends on the extension of the transverse separations. - The fact that the transverse separations extend such that the
adjacent segments projections 12 and recesses 11 achieves an increased torsional stiffness of the line receiving channel 1 and thus likewise of the line guiding arrangement, since the adjacent segments are not displaceable relative to each other crosswise to the longitudinal direction of the line guiding arrangement. - As shown in FIG. 1, in the extended state of the line guiding arrangement, the
projections 12 engage therecesses 11. - When the line guiding arrangement is caused to bend into a loop shape, the
segments adjacent segments projection 12 moves out ofrecess 11. In the illustrated embodiment theprojection 12 has the shape of a rectangular tab. Therecess 11 is complementary to theprojection 12. The parallel extendingsurfaces projection 12, which extends intorecess 11, when the adjacent segments reach the maximally permissible angle of tilt a. This configuration of therecess 11 andprojection 12 has the advantage that even in the tilted state of the segments, the line receiving channel exhibits a greater torsional stiffness. Therefore, it is preferred to select the length of the projection or recess in the longitudinal direction of the line guiding arrangement such that theprojection 12 extends in part into therecess 11 even in the tilted state of adjacent segments. This advantage is realized not only with the configuration ofrecess 11 andprojection 12 in the cover portion, but also in the side wall portions. - FIG. 2 illustrates a further embodiment of a
line receiving channel 13. The basic construction ofline receiving channel 13 corresponds to that of line receiving channel 1. Like parts ofline receiving channel 13 and line receiving channel 1 are provided with like numerals. - The

channel 37 for a line guiding arrangement for running at least one line. Thechannel 37 comprises abase wall portion 40, acover portion 41, andside wall portions channel 37 is made as a hollow, rectangular section. - The
channel 37 is subdivided bytransverse separations 44 into a plurality ofsegments cover portion 41, and they continue in theside wall portions base wall portion 40. Thetransverse separations 44 terminate inopenings 45, which permit reducing the stress of the channel in the region of the bending axes. - The transverse separation of two adjacent segments is formed such that the one segment has a T-shaped
recess 46 and the other segment a T-shapedprojection 47 extending into therecess 46. - The

recess 46 comprises asection 52 for the movement oftab 48. Therecess 46 comprises arectangular head receptacle 53 for the movement ofhead 49 ofprojection 47. As best seen in FIG. 5, the longitudinal extent ofhead receptacle 53 is greater than the longitudinal extent ofhead 49, so that theprojection 47 andrecess 46 permit tilting of adjacent segments. - FIG. 6 shows two adjacent segments of the
channel 37 in a tilted state. Indicated at ΔS is the distance, by which thehead 49 is displaced inside thehead receptacle 53 substantially in the longitudinal direction ofchannel 37. The angle of tilt α is proportionate to the distance ΔS. A corresponding adaptation of the distance ΔS permits adjustment of an angle of tilt α. - The
head 49 comprises stop surfaces 50, 51 that contact stop surfaces 54, 55 ofhead receptacle 53. The stop surfaces 51, 55; 50, 54 also limit the angle of tilt α. - A line guiding arrangement may be constructed by using two
channels 37. Thechannels 37 are joined to each other in spaced relationship by suitable connecting members. In the space between the parallel extending channels, it is possible to arrange lines. - In the illustrated embodiment of FIG. 5, the
channel 37 is a hollow section. The basic construction of thechannel 37 may also be used to the end that it serves as a line receiving channel. In such an instance, a line can be inserted directly into the line receiving channel. - FIG. 7 illustrates a further embodiment of a

receptacle 53 is greater, when viewed in the tilting direction ofadjacent segments channel 56, than thehead 49, so that it is possible to tiltadjacent segments head 49 and thereceptacle 53 are shaped such that they cause a limit of the angle of tilt α. - During the tilting, the
projection 47 slides out of therecess 46. Preferably, theprojection 47 is dimensioned in the longitudinal direction ofchannel 56 such that it continues to extend withinrecess 46 even upon reaching a maximum angle of tilt α. A relative displacement of thesegments channel 56 is prevented in particular byprojection 47 andrecess 46. - As previously described, the
