Description

Technical Field

[0001] The invention generally relates to a device for the protected routing of at least one line, such as a cable, a hose or the like, between two connection points, at least one of which is movable, typically between a fixed connection point and a movable connection point. Background Art

[0002] Typically, pipeline guides can accommodate multiple pipelines. A very common example is the so-called energy guide chain. These chains consist of individual chain links, which are typically assembled from multiple separate components. Patents DE 3531066 C2, EP 0803032 B1, and EP 1381792 B1 from the applicant describe such chains, each with links consisting of two, four, or six separate components. These chains have proven to be very practical. While they are sturdy and reliable, they are complex to manufacture or assemble. Energy guide chains typically feature an articulated connection between two connected chain links, using a rotating hinge or hinge.

[0003] The present invention relates to a generic line guiding device for movably guiding at least one supply line, wherein at least one longitudinal section of the line guiding device comprises a plurality of segments and is manufactured in one piece, wherein the segments are connected to one another by flexible connections in the longitudinal direction, so that the segments can be pivoted relative to one another within a pivoting plane, in particular with the aim of forming a deflection arc during movement of the line guiding device. The segments define a receiving space into which at least one supply line can be inserted so as to remain guided therein during operation.

[0004] This type of pipeline guide is not a true chain, or does not have a distinct rotating hinge, and is sometimes referred to in the art as a "belt chain."

[0005] Partially or completely one-piece "belt chains" are known, for example, from US Pat. No. 3,473,769 A, EP 0 724101 A1, WO 00 / 11772 A1, or DE 10 2007 038 747 A1. These pipeline guides are typically manufactured using extrusion technology and subsequently require post-processing, particularly separate post-processing to produce individual segments. This is relatively complex, and adjustments to the shape (e.g., changing the radius or minimum pivot angle) are not easy.

[0006] On the other hand, due to geometrical reasons, the production of such one-piece pipeline guides (usually at least in sections) using injection molding is more difficult. WO 98 / 40645 A1 proposes a solution in this regard. Here, a foldable plastic protective element, essentially a segment, is produced in one piece using injection molding, essentially in a substantially flat, planar structure. The segment has flexible bridges, and by folding, individual sections of the segment can be deformed into links that define a circumferentially closed receiving space. This also requires complex post-processing (usually manual) to produce a usable pipeline guide.

[0007] Another solution is proposed in DE 198 60 948 A1 of the applicant, in which the individual segments are produced in one or more parts by injection molding, similar to conventional chain links, and are then placed on a flexible sliding belt. Summary of the Invention

[0008] The object of the present invention is therefore to provide a configuration which enables the production of one-piece sections using plastic injection molding and in particular simplifies the production of directly usable components of a line guiding device, ie components which do not require subsequent processing.

[0009] This is achieved with the aid of a line guiding device according to claim 1 and a one-piece component of the type described in claim 15 .

[0010] A line guiding device is proposed for movably guiding at least one supply line (e.g., an electrical or data cable) between two connection locations, at least one of which is movable relative to the other connection location. At least one longitudinal section of the line guiding device comprises a plurality of segments and is manufactured in one piece. The segments can be connected to one another via flexible connections in the longitudinal direction, allowing them to pivot relative to one another within a pivoting plane, in particular to form a deflection arc when the line guiding device is moved. The segments typically define at least one receiving space into which at least one supply line can be inserted for guidance or retention therein during operation.

[0011] According to the core of the present invention, each segment has a central region with a main plane extending perpendicularly to the pivot plane, and the segments are configured with a first receiving space on a first side of the main plane and a second receiving space on a second, opposite side of the main plane. This configuration with receiving spaces on both sides allows the central region to be manufactured in the mold with the central region oriented parallel to the closing or demolding direction, or perpendicularly. This results in significant simplifications, as demolding can be significantly simplified, or the segments can be manufactured in simpler molds (so-called split molds, without slides).

[0012] In particular, the first receiving space is bounded by a first tab transverse to the main plane, a first side member held by this tab, and a first main surface of the central region. Similarly, a second receiving space is located on the second, opposite side of the main plane. This second receiving space is bounded by a second tab transverse to the main plane, a second side member held by this tab, and a second main surface of the central region. This geometry allows for simplified, ready-to-use production using a preferred injection molding process, wherein all critical areas of the segment can be manufactured in a simple, one-piece manner.

[0013] According to the present invention, it is particularly provided that the first and second tabs, as well as the first and second side parts, are each manufactured in one piece with the central region, while at least one bendable hinge region is manufactured in one piece with the central regions of two longitudinally consecutive segments to provide a flexible connection therebetween. Consequently, all critical structural regions of the longitudinal segment can be manufactured as a single-piece plastic component.

[0014] The proposed design positions the typically open side opposite the tab (for inserting or removing the pipeline) so that the pipeline can be inserted or removed approximately perpendicularly to the pivot plane. This prevents the pipeline from accidentally coming out during operation. With the proposed design, the segments are configured so that the reaction forces acting on the pipeline during movement in the deflection arc act radially outward or radially inward on the central region or side members, rather than on the tab or the insertion opening that typically lies opposite the tab.

[0015] Depending on the orientation, the proposed design with receiving areas arranged on both sides of the central area can also offer the advantage that the weight load of the overhanging area acts parallel to the main plane on the central area or the flexible hinge area, and thus these areas can achieve a high load-bearing capacity even with a relatively small wall thickness, just like the webs of the bracket. The central area or the flexible hinge area can have a dimension perpendicular to the pivot plane that can account for at least a majority of the corresponding dimension of the receiving space, preferably at least 80%, for example 100%, of this dimension of the receiving space.

[0016] The pipeline guiding device according to the invention has no significant rotary joints and, in particular, does not require separate sliding or connecting straps for achieving a flexible connection of the chain links.

[0017] In order to define the pivoting angle of the segments that can pivot relative to one another, it is preferably provided that at least one end face of the first and second side parts, facing away from one another and pointing in the longitudinal direction and / or extending transversely to the pivot plane, respectively, acts together as a stop for limiting the pivoting angle. In particular, the respective first end face of the first side part can limit the pivoting angle on one side (i.e., in one rotational direction) in a straight position, and / or the respective second end face of the second side part can limit the pivoting angle on the other side (i.e., in the other rotational direction), for example, in a maximum bent relative position when forming a deflection arc.

[0018] Preferably, at least some of the one-piece longitudinal segments can be pivoted relative to a straight, straight position (e.g., to form a straightened section) in only one rotational direction to form a deflection arc. For this purpose, it is particularly preferred that the first and second side parts have different lengths in the longitudinal direction to achieve different stop effects and differently limit the pivoting angle. However, the proposed configuration can also be advantageously used for pipeline guides having a rearward bend (opposite to the deflection arc).

[0019] To better retain the pipeline, a retaining region is preferably provided on at least one of the side members, in particular a retaining region projecting toward the central region opposite the tab, for securing the pipeline in the corresponding receiving space. The retaining region can be formed by a separately manufactured retaining element that is mounted on the segment. However, it is particularly preferred that the retaining region be manufactured integrally with the side members, in particular, with the side members, tabs, and central region. This can preferably be achieved by providing a molded recess in the tab corresponding to the retaining region, wherein the molded recess is located opposite the retaining region and its dimensions, when projected onto the pivot plane, correspond at least to the area of ​​the retaining region, and the tab has a larger dimension, at least in the longitudinal direction, than the retaining region. This enables the retaining region to be manufactured using a simple, so-called split mold using an injection molding process, as the molded recess allows the retaining region to be removed from such an injection mold.

[0020] In general, the pipeline guiding device can be assembled in multiple pieces from multiple guide parts connected in the longitudinal direction, depending on the total length desired for the application. These guide parts can each include multiple segments and be manufactured in one piece according to the above solution.

[0021] In particular, each guide element can comprise a carrier belt formed from successive, integrally connected central regions and articulation regions, in particular a carrier belt having a main plane perpendicular to the pivot plane and / or extending in the longitudinal direction. The two longitudinal ends of the carrier belt can each be provided with one of two cooperating connectors for connecting the individual guide elements to one another in the longitudinal direction.

[0022] In a preferred embodiment of the connector, at least one first connector is formed by the central region of an end-side segment of the guide element, and / or a second connector is formed at the free end of the hinge region of the guide element. In another preferred embodiment of the connector, it is provided that the cooperating connectors implement a positive-locking and / or non-positive-locking connection for the support strips of two consecutive guide elements, preferably such that the connection can only be established and / or released in a direction perpendicular to the pivot plane.

[0023] Particularly preferably, the connector is designed such that the connection can be produced without tools, preferably only in a direction perpendicular to the pivot plane.

[0024] The cooperating connectors preferably have contact surfaces perpendicular to the pivot plane, which contact surfaces bear against each other in the connected state, thus enabling a stable connection in the load-bearing cable.

[0025] Furthermore, preferred embodiments include one or more of the following features or combinations:

[0026] Each longitudinal section or each guide element comprises at least three one-piece segments, in particular segments of identical construction; and / or

[0027] - in each segment, the side members are substantially parallel to the main plane, and / or the webs are substantially perpendicular to the main plane of the central region; and / or

[0028] - each segment has a cross section perpendicular to the longitudinal direction that is substantially double-U-shaped, UU-shaped or └┴┘-shaped and / or has three substantially parallel legs formed by outer parts and a central area located between them; and / or

[0029] - at least one longitudinal section or guide has an articulation region which is pre-bent in the rest position or segments which are pre-swiveled relative to one another, which enables prestressing and also facilitates one-piece production in a mold; and / or

[0030] Each segment is designed such that it limits the movement of the pipeline received in the receiving space in at least three directions perpendicular to the main plane, in particular in two directions perpendicular to the main plane and in at least one direction parallel to the pivoting plane, in particular vertically downward.

[0031] In a preferred embodiment, the articulation region is plate-shaped with a main surface perpendicular to the pivot plane and with a reduced wall thickness compared to the central region. The wall thickness is preferably several times smaller, for example at least three times smaller, than the length of the articulation region in the longitudinal direction and / or several times smaller, for example at least three times smaller, than the width of the articulation region perpendicular to the pivot plane.

[0032] The central region, which is connected in one piece by means of the articulation region, preferably acts together with the articulation region as a support belt and / or defines a neutral axis of the line guiding device.

[0033] The line guiding device is preferably intended for horizontal applications, wherein the neutral axis or the carrier belt is particularly oriented vertically. However, the line guiding device can also be used in the same configuration for a conventional vertical arrangement, with a lower section and an upper section.

[0034] In a particularly preferred embodiment, each longitudinal section or each guide is made in one piece by plastics, especially by injection molding. Here, the guide is preferably made of consistent plastics of material, especially in the hinge area and other zones (as tabs and side parts), adopts consistent plastics.

[0035] For end-side fastening at the end connection locations, at least some of the central regions preferably have fastening openings extending in the main plane, in particular for fastening screws. This avoids the need for separate end connection components, as the fastening function is already integrated into the guide or component of the line guiding device.

[0036] The invention further relates to a one-piece guide element for a line guiding device for guiding at least one supply line (e.g. an electrical or data cable) movably between two connection points, at least one of which connection points is movable relative to the other connection point, wherein the guide element comprises a plurality of segments, in particular at least three segments, and is manufactured in one piece, wherein the segments are connected to one another by flexible connections in the longitudinal direction, such that the segments can be swiveled relative to one another within a swivel plane in order to form a deflection arc when the line guiding device is moved, wherein the segments define at least one receiving space in which at least one supply line can be placed and held.

[0037] According to the invention, the segments each have a central area with a main plane perpendicular to the pivot plane, with a first receiving space on a first side of the main plane, the first receiving space being delimited by a first web transverse to the main plane and a first side part held by this web, and a first main surface of the central area, and with a second receiving space on a second side of the main plane, the second receiving space being delimited by a second web transverse to the main plane and a second side part held by this web, and a second main surface of the central area.

[0038] Furthermore, according to the invention, the first and second tabs and the first and second side parts can each be manufactured in one piece with the central region, and / or the bendable hinge region can be manufactured in one piece with the central region of two respective longitudinally consecutive segments to provide a flexible connection therebetween.

[0039] Accordingly, the proposed individual component or guide element can be manufactured relatively simply as a plastic injection-molded part. It can have the features according to one or more of the developments described above, or according to the features of any of the dependent claims 2 to 14.

[0040] The proposed line guiding device can be produced from cost-effective individual components or guide elements and can be assembled with relatively little effort.

[0041] The proposed pipeline guiding device is particularly suitable for relatively short strokes or movement lengths, usually ≤ 3 meters.

[0042] The proposed cable guide device is particularly suitable for use in server cabinets, which include a rack for mounting retaining rails for pull-out servers. The cable guide device is provided for supplying power to the pull-out servers, for example, when they are pulled out for maintenance purposes. In principle, the present invention is particularly suitable for cable guide applications where the particularly flat design of the device is advantageous, such as in various pull-out systems or server cabinets. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Further details, advantages and features of the present invention can be derived from the following description of two exemplary embodiments in conjunction with the accompanying drawings. Therein are shown:

[0047] Figures 3A-3B According to a second embodiment of the pipeline guiding device according to the invention, there is a guiding part manufactured in one piece ( Figure 3A ), whose segments can also swing backward relative to each other (see Figure 3B ). DETAILED DESCRIPTION

[0048] Figure 1 A line guiding device 100 for use in a preferably horizontal application is shown in a top view or from above. The line guiding device 100 serves to guide at least one supply line, such as an electrical or data cable (not shown), movably or dynamically between two connection locations A, B. At least one of the connection locations A, B is movable relative to the other, e.g. Figure 1 The pipeline guiding device 100 has a plurality of consecutive longitudinal sections, which are formed by individual guiding elements 11A...11E connected to each other in the longitudinal direction L. Each of the guiding elements 11A...11E, as described below in conjunction with Figures 2A-2E As described in more detail, it is manufactured in one piece and has a plurality of one-piece segments 12 , 12A that follow one another in the longitudinal direction L.

[0049] The chain link segments 12 of the guide elements 11A ... 11E are each flexibly connected to one another in the longitudinal direction L via a curved joint region 13, i.e., a predetermined elastically bendable joint region 13 forms a flexible connection between the individual segments 12. As a result, the segments 12, which are themselves relatively rigid to bending, can be pivoted relative to one another in a pivot plane E, which corresponds to the pivot plane E. Figure 1 Drawing plane. In preferred horizontal applications, the pivot plane E, in which the longitudinal direction L lies, is substantially horizontal. When the movable connecting point A is moved back and forth in the longitudinal direction, the pipeline guiding device 100 forms a deflection arc U, through which the segments 12 are deflected. Alternatively, the pipeline guiding device 100 can also be used in vertical applications in a substantially vertical pivot plane E, or with a vertically arranged deflection arc U.

[0050] Figures 2A-2E One of a plurality of structurally identical, one-piece guide elements 11A...11E (here, for example, guide element 11B) is shown in its unbent, resting state. The articulation region 13 is manufactured with a slight pre-bend, so that the individual segments 12 are already slightly bent relative to one another in the unloaded, resting position. This creates a prestress and facilitates the production of the one-piece guide elements 11A...11E in a simple injection mold. The guide elements 11A...11E are preferably one-piece injection-molded parts made of thermoplastic, optionally with fiber reinforcement.

[0051] Figure 2A and Figure 2B Shown is the corresponding Figure 2C The cross section of the section lines AA and BB in the vertical direction is perpendicular to the swing plane E or Figure 2C plane.

[0052] like Figures 2A-2BAs can be seen most clearly, the segments 12 each have a central region 14 with a main plane H oriented in the longitudinal direction, which is perpendicular to the pivot plane E and the pivot plane E. Figures 2A-2B On a first side of the main plane H, each segment 12 forms a first receiving space 15A, and on an opposite second side of the main plane H, a second receiving space 15B is formed.

[0053] First receiving space 15A is bounded by first web 16A, first outer part 18A disposed on web 16A, and first main surface 14A of central region 14. First web 16A extends substantially transverse to main plane H or parallel to pivot plane E and holds first side part 18A in position against central region 14. First side part 18A extends or is arranged substantially parallel to main plane H or main surface 14A of central region 14. Similarly, second receiving space 15B is bounded by first web 16B, second outer part 18B disposed on web 16B, and second main surface 14B of central region 14. Second web 16B likewise extends substantially transverse to main plane H or parallel to pivot plane E and holds second side part 18B in position against central region 14. Second side part 18B extends or is arranged substantially parallel to main plane H or main surface 14B of central region 14.

[0054] exist Figures 2A-2F In the embodiment, the second side member 18B has different dimensions than the first side member 18A, in particular it is shorter in the longitudinal direction (compared to, for example, Figures 3A-3B On the contrary). The tabs 16A and 16B hold the side parts 18A or 18B in the central area. At the same time, the tabs 16A, 16B serve as support for the pipelines in the corresponding receiving spaces 15A, 15B, depending on the application, downward in horizontal applications (e.g. Figure 1 The side parts 18A and 18B hold the pipelines (not shown) in the receiving spaces 15A and 15B in a radially outward or inward direction relative to the deflection arc U (i.e., in a lateral or vertical direction depending on the application).

[0055] like Figure 2A As can be seen most clearly, the first and second tabs 16A, 16B and the first and second side members 18A, 18B, respectively, are manufactured integrally with the central region 14 .

[0056] On each of the side parts 18A, 18B, a holding area 17A, 17B is provided opposite the tabs 16A, 16B, which protrude inwardly toward the central area 14. The holding areas 17A, 17B serve to hold the pipeline in the corresponding receiving space 15A, 15B. Figures 2A-2BIn the upward direction. Between the two holding areas 17A, 17B, which are preferably of equal size, and the central area 14, a free access opening is provided for inserting or removing a line (not shown) into or from the corresponding receiving space 15A, 15B. The holding areas 17A, 17B have the same basic shape, approximately D-shaped, with rounded corners on the side facing the central area 14.

[0057] In each tab 16A or 16B, a profiled recess 19A, 19B is provided, which corresponds to the opposite holding area 17A, 17B. In the embodiment shown, the holding areas 17A, 17B and therefore the profiled recesses on each of the two sides or receiving spaces 15A, 15B have the same basic shape, for example, a roughly D-shape. The profiled recesses 19A, 19B are opposite the holding areas 17A, 17B, respectively, and their dimensions correspond at least to the bottom area of ​​the holding areas 17A, 17B or their projection on the swing plane E. Accordingly, the tabs 16A, 16B have a dimension that is greater than the holding areas 17A, 17B, at least in the longitudinal direction L (preferably also perpendicular to the main plane H), as shown in FIG. Figure 2D This is most clearly visible from the rear view. This simplifies the mold, as no slides for undercuts are required. Each retaining area 17A, 17B is preferably also connected to the rest of the segment 12 or 12A via side parts 18A or 18B and tabs 16A or 16B in one piece with the central area 14 and manufactured, in particular using an injection molding process. Alternatively, retaining elements or retaining tabs that are subsequently installed may be provided.

[0058] Figure 2C Also shown are the first end faces 181A, 181B of the first side part 18A and the second end faces 182A, 182B of the second side part 18B. Figure 1 , lower section, for example, at the guide 11D), the end faces 181A, 181B of the first side part 18A facing away from each other, pointing in the longitudinal direction and extending transversely to the pivot plane E, each act together as a stop. In order to limit the pivot angle α2 of the two segments 12 relative to each other in the direction of full deflection or to form a deflection arc in the relative position of the maximum bending of the segments 12 (see Figure 1 ), the end faces 182A, 182B of the second side part 18B facing away from each other, pointing in the longitudinal direction and extending transversely to the pivot plane E, each act together as a stop. The end faces 182A, 182B are arranged to extend obliquely at a respective angle α2 to each other, so that the end faces 182A, 182B can rest flush against each other when the stop occurs.

[0059] Figure 1-2 The different functions of the stopper are Figure 3B This becomes apparent when comparing the embodiments in FIG.

[0060] The central region 14 and the articulated region 13 form a carrier belt within each guide element 11A...11E, which extends, in particular, with its main plane H perpendicular to the pivot plane E and approximately defines a longitudinal direction L. At each longitudinal end of the carrier belt formed by the central region 14 and the articulated region 13, one of two cooperating, correspondingly configured connectors 20A, 20B is provided. By means of these connectors 20A, 20B, a plurality of guide elements 11A...11E can be connected to one another in the longitudinal direction for a desired length of the pipeline guiding device 100. If necessary, the end guide element 11A or 11E can be cut to the desired length, e.g. Figure 1 shown.

[0061] like Figures 2C-2E As shown in more detail, each articulation region 13 is manufactured in one piece or integrally with each of the central regions 14. Articulation regions 13 of the same type are inherently elastically bendable within the swing plane E, thereby achieving a flexible connection of two segments 12 that are consecutive in the longitudinal direction L. The bendability of the articulation region 13 is achieved in particular by a significantly reduced wall thickness of the articulation region 13 compared to the structural length in the longitudinal direction L or the structural height perpendicular to the swing plane. In this case, the wall thickness W is preferably in the range of approximately 5%-20%, in particular approximately 7.5%-15% of the structural length and / or structural height. As shown in FIG. Figure 2E As can be seen in FIG, the bendable articulation region 13 can in this respect be embodied in a plate-like manner and preferably extends essentially in the main plane H (at least in the straightened state).

[0062] Correspondingly, if Figure 2A As can be seen from the figure, the wall thickness of the central region 14 measured between the main faces 14A, 14B is significantly greater than that of the articulation region 13. This is preferably at least three times the wall thickness W of the articulation region 13. Therefore, the central region 14 is relatively rigid to bending and preferably rigid to torsion compared to the articulation region 13, so that when the segment 12 is in the deflection arc U( Figure 1 ) is bent, only the hinge area 13 is elastically deformed by bending (Note: Figure 1 In other words, in FIG. 3 , for technical reasons, the actual arc-shaped curved contour of the hinge region 13 is not shown).

[0063] exist Figures 2A-2EIn the embodiment of the present invention, each one-piece guide element 11A ... 11E has a total of four segments 12, 12A, wherein all segments are substantially identically sized and identically configured, except for the end segment 12A, which has a specially configured central region 14C. A connector 20B, for example, a male or male connector, is provided on the central region 14C of the end segment 12A for connection to a corresponding, for example, female, connector 20A of the next guide element 11A ... 11E.

[0064] exist Figures 2C-2E , the connectors at the opposite longitudinal ends are shown in greater detail. Here, a female connector 20A is provided at the free end of the end-protruding hinge region 13 and is conjugated with a male connector 20B (here, at the central region 14C of the other end region). Connectors 20A, 20B are configured with complementary outer contours, so that in the assembled state, they create a closed shape that corresponds to the outer contours of the other central regions 14 of the structurally identical segments 12 of the guide element 11A...11E.

[0065] The engagement of the connectors 20A, 20B for connecting the two guide elements 11C, 11D is achieved by movement in an engagement direction F substantially or exactly perpendicular to the swing plane E, as shown in FIG. Figure 2F The connectors 20A, 20B act together to achieve a positive and non-positive connection of the carrier strips of two consecutive guides. This connection can preferably only be established in a direction perpendicular to the pivot plane, in particular without tools, and can preferably only be disassembled non-destructively using suitable tools. Figures 2D-2F As can be seen in FIG, the connectors 20A, 20B form corresponding abutment surfaces 201A, 201B perpendicular to the pivot plane E, which abut firmly against one another in the connected state.

[0066] With the exception of segment 12A having a central region 14C and end-side connectors 20B, the other three segments 12 have through-going fastening openings 24 in their central regions. A recessed portion 24A with a hexagonal opening, for example for a hexagonal nut or a cylindrical screw, is provided at one end of the fastening opening 24, and a conical recessed portion 24B for a countersunk screw is provided at the opposite end of the fastening opening 24. By means of the fastening opening 24 and the coaxial recessed portion 24A or 24B, each segment 12 can be selectively fastened at a connection point A, B, wherein excess length can be removed by cutting off at the articulated connector 13.

[0067] refer to Figures 3A-3B , briefly describes a second embodiment of a pipeline guiding device 300 composed of a plurality of one-piece guiding members 311, wherein only the Figure 1-2. Each guide 311 also has a plurality of segments, each having a central area 14 and an articulation area 13, and receiving spaces 15A, 15B on both sides thereof. However, unlike Figure 1 The difference is that, Figure 3B As shown, the guide element 311 can be deformed in two pivoting directions or in opposite bending directions U1 or U2. In the guide element 311, the segments have identically dimensioned first and second tabs 316A and 316B, as well as identically dimensioned first and second side parts 318A and 318B, on both sides, i.e., at each receiving space 15A, 15B. In other words, the end faces 381A, 318B have the same angular limitation or stop effect on both sides of the support chain or main plane. Slightly different angular limitations can also be achieved. The retaining areas 317A, 317B are also designed identically. Therefore, the pipeline guiding device 300 can also be used in applications with a backward bend (e.g., in the opposite bending direction U2). Figures 3A-3B The guide element 311 can also be produced economically as a one-piece plastic injection-molded part.
