Description

TECHNICAL FIELD

[0001] The present invention generally relates to a pipeline guiding device for pipelines such as cables, hoses or the like, in particular in clean room applications, i.e. to a pipeline guiding device which is able to reciprocate with a turning arc between two segments from a first end and a second end.

[0002] The present invention particularly relates to an improved end fastening for such a dynamic pipeline guiding device. BACKGROUND

[0003] Pipeline guiding devices for clean room applications of the present class are currently considered to typically have one or more longitudinal and flexible casings, which usually have channel-like receptacles for pipelines, which extend through in longitudinal direction and next to each other in transverse direction. Such hose-like casings or rather their receptacles are also referred to as so-called "pods" and are particularly protected against escaping of abrasion particles generated when the pipelines move.

[0004] For most applications, a first end fastening device for a first end of the pipeline guiding device and a second end fastening device for a second end of the pipeline guiding device are provided. The end fastening devices serve to attach the ends on one of two attachment sites, for example on a machine, wherein at least one of the attachment sites is movable relative to the other.

[0005] An embodiment of such a pipeline guiding device with a specifically adapted end fastening device is known from WO 2021 004654 A1.

[0006] Another pipeline guiding device of the present class with a support chain and a particular end fastening device is described in DE 10 2012 100 290 B4, however, which is relatively expensive in its construction, since additional components are provided for end-side closure of the receptacles.

[0007] In the constructional manner of the generic kind, the pipeline guide device has an elongate flexible sheath which is reciprocally movable and has a plurality of channel-like receptacles for pipelines which extend in the longitudinal direction from a first end to a second end. The receptacles are arranged laterally side by side in the transverse direction and the sheath is reciprocally movable, in particular with two sections with a turning arc therebetween. Furthermore, the pipeline guide device has two support chains which extend in the longitudinal direction from the first end to the second end of the flexible sheath in order to support the flexible sheath and which comprise a plurality of individual links which are hingedly connected to one another. Each link has a main body with two outer sides and corresponding first and second hinge elements which are configured for an oscillatable connection of two links in a plane which is substantially perpendicular to the transverse direction. On the end of the sheath, a first end fastening device for fixing the first end of the sheath and a first end of the support chain and a second end fastening device for fixing the second end of the sheath and a second end of the support chain are respectively provided.

[0008] The end fastening device according to the preamble of claim 1 is known from DE 10 2012 100 533 A1. Therein, each of the end-side end fastening devices has at least one link holding element for locking the associated end-side link of the support chain in the longitudinal direction, in particular between two clamping parts. SUMMARY

[0009] A first task of one aspect of the invention is to simplify the constructional manner of the end fastening device, in particular with regard to the number of components, and preferably the assembly and disassembly.

[0010] A second, independent task of another aspect of the invention is to improve the clamping parts of the end fastening device, in particular to simplify the assembly and disassembly.

[0011] FIRST ASPECT

[0012] In order to solve the first-mentioned task, the pipeline guide device according to the preamble of claim 1 or the construction kit for an end fastening device according to the preamble of claim 2 is improved.

[0013] In the simplest embodiment, the improvement has been achieved by the following:

[0014] - the support chain has two end-side links which respectively comprise or have and / or form two locking protrusions which protrude laterally on one of the outer sides in a direction which is substantially parallel to the transverse direction of the support chain or of the sheath, in particular in a manner which exceeds the first and second hinge elements of the end-side link;

[0015] - the link holding elements of the two end fastening devices each have two laterally and in the transverse direction oppositely directed holding recesses; and

[0016] - the locking protrusions of the two end side links each engage into the holding recesses in the associated link holding element for locking, in order to lock the support chain in the longitudinal direction.

[0017] The configuration of the lateral locking protrusions on the end links in combination with the corresponding configuration of the special link holding elements allows the use of the same type of locking or longitudinal securing of the support chain on both ends of the support chain, so that the number of components is reduced. Furthermore, the operation can be significantly simplified, since the proposed solution allows securing with the respective two, preferably identical, holding elements of each end link.

[0018] The locking protrusions on the end side links are dedicated to the purpose of locking and are arranged in addition to the hinge elements, in particular in addition to the hinge bolts, so that they can also be implemented more robustly and, for example, with a larger diameter if necessary.

[0019] Furthermore, the proposed solution allows the jacket to be clamped with the end links between the appropriately configured holding elements, so that a better closure for preventing particles from escaping from the jacket can be achieved.

[0020] Correspondingly, the proposed construction kit comprises at least one support chain of this type, preferably two support chains, which extend in the longitudinal direction from a first end to a second end and which comprise a plurality of individual links which are hingedly connected to one another, wherein each link has a main body with two outer sides and corresponding first and second hinge elements which are configured for an oscillating connection of two links in a plane which is substantially perpendicular to the longitudinal direction. Furthermore, the construction kit comprises two link holding elements for locking the associated end side link on the first or second end of the support chain, in particular between two clamping plates, in the longitudinal direction.

[0021] According to the invention, the construction kit for the end fastening has the following features:

[0022] i) the support chain has two end side links which are determined for locking in the longitudinal direction and each comprise or have and / or form two locking protrusions which protrude beyond the first and second hinge elements on one of the outer sides in a direction which is substantially parallel to the transverse direction, in particular laterally;

[0023] ii) the two chain link holding elements each have two laterally and in the transverse direction oppositely directed holding recesses; and

[0024] iii) the locking protrusions of the two end-side chain links, for locking, cooperatively interact with the respective two holding recesses in the associated chain link holding elements.

[0025] Irrespective of the construction of the sleeve and the support chain used, with this construction kit the aforementioned advantages can also be achieved, namely that the construction kit is suitable and determined for implementing an improved end fastening.

[0026] In one embodiment it can be provided that each of the end-side chain links is associated with a pair of chain link holding elements, which are arranged or can be arranged facing one another and oppositely with respect to a main plane parallel to the longitudinal direction and the transverse direction, and each have two oppositely directed side walls extending in the longitudinal direction, wherein each chain link holding element of the pair between the side walls forms a receiving portion for the end-side chain link open with respect to the main plane and in the longitudinal direction, wherein the receiving portion preferably receives at least 25% up to nearly 50% of the construction height of the end-side chain link, wherein in each side wall one holding recess is provided, in particular open toward the receiving portion and toward the main plane, so that the two oppositely directed holding recesses each at least partially, preferably substantially completely, surround one of the locking protrusions.

[0027] Here, all chain link holding elements can preferably be implemented identically constructed, which reduces the number of components and simplifies handling.

[0028] In one embodiment it can be provided that the locking protrusions are preferably provided in a central region of the chain links in the longitudinal direction between the end regions with the corresponding first and second hinge elements.

[0029] In one advantageous embodiment of the chain link holding elements it can be provided that the oppositely directed side walls extending in the longitudinal direction of each chain link holding element have an upper face substantially parallel to the main plane, at which a clamping element or claw element is provided for longitudinally securing a sleeve surrounding one of the support chains. A better securing of the entire pipeline guide including the sleeve is thus achieved.

[0030] In another advantageous embodiment of the chain link holding elements it can be provided that all chain link holding elements are identically constructed and implemented in one piece and are preferably made of plastic, in particular as injection-molded parts.

[0031] In a further advantageous embodiment of the chain link holding element, the chain link holding element or each chain link holding element can form on the front side an open, in the longitudinal direction, receiving portion for the end-side chain link relative to the main plane and on the back side has on both longitudinal ends tongue portions facing one another for connection, in particular in the form of a keyway connection, to one of two diverging end-side holding recesses on the clamping plate of the end fastening portion, respectively.

[0032] In a further advantageous embodiment of the chain link of the support chain, it can be provided that the chain link is produced as a one-piece body made of plastic, in particular as an injection-molded part. Here, the two diverging locking protrusions of the end-side chain link can each be formed by the end of a separate pin, peg or the like which passes through a transverse opening in the chain link and projects laterally on both sides. Alternatively, the two diverging locking protrusions of the end-side chain link can be produced in one piece with the body of the chain link.

[0033] Preferably, the end chain link and the chain link holding element are embodied such that the locking protrusions are held in the holding recesses in a form-locked and / or tool-free releasable manner.

[0034] Furthermore, a correspondingly improved support chain according to the preamble of claim 8 is proposed. The support chain is characterized according to the first aspect in a corresponding manner in that it has two end-side chain links which each comprise two diverging locking protrusions which are arranged in particular in addition to the first and second hinge elements and each project in a direction which is substantially parallel to the transverse direction, in particular laterally outwards on one of the outer sides beyond the first and second hinge elements. Furthermore, the two end-side chain links are characterized in that on each end chain link a locking protrusion is arranged for locking the support chain in the longitudinal direction by interaction with a corresponding holding recess of an end fastening portion. Here, on at least one end-side chain link, preferably on both end-side chain links, the locking protrusion can be arranged on the middle region, in particular on the frame region.

[0035] Second aspect

[0036] In order to solve the second task of the solution, an improved clamping plate according to claim 10 is proposed according to the independent second aspect. This clamping plate has two short, narrow sides which are parallel to a longitudinal direction which corresponds to the longitudinal direction of the support chain to be fastened, two long, main sides or end sides which are parallel to the transverse direction and two diverging main faces which are parallel to the main plane

[0037] According to a second aspect, the clamping plate is characterized in that on each main side or end side an end-side holding groove is provided which is open in the longitudinal direction, which holding groove extends through the same cross section from one narrow side to the other narrow side and there opens out in the transverse direction, so that in particular a holding element, for example for an end of a line to be guided or for an end-side link, can be push-in and displaceably mounted on the clamping plate by means of a tongue which fits into both holding grooves.

[0038] The clamping plate can be embodied plate-like, in particular with a rectangular base surface and preferably flat, planar main surfaces.

[0039] This flat design reduces the material outlay required and enables the use of the same clamping plate for constructions with different structural heights of the jacket to be clamped in, i.e. with different line diameters. The clamping plate can be cut from a metal profile, in particular an extruded profile, for example made of aluminum, already having the holding grooves and can be produced cost-effectively. In order to simplify handling, the clamping plate can be embodied symmetrically with respect to at least two of the three center planes. Here, as "center planes" are meant the center planes parallel to the main planes, the center planes perpendicular to the main planes along the longitudinal direction and the center planes perpendicular to the main planes along the transverse direction.

[0040] The clamping plate can be embodied substantially symmetrically with respect to all three center planes.

[0041] Preferably, the clamping plate has at least two, preferably three fastening holes on both sides of the narrow sides. These fastening holes are preferably arranged along the longitudinal direction and close to the narrow sides.

[0042] The invention also relates to a construction kit comprising two clamping plates and at least four extension screws, which each have an outer thread and an inner thread on the screw head which matches the outer thread and a respective inner thread bush which matches the outer thread. The advantage here is that the end fastening can be assembled and disassembled layer by layer, which greatly simplifies handling in particular in the case of the replacement of only one of a plurality of jackets.

[0043] In connection with the screw connection, each clamping plate can have a sink on each narrow side at the at least two fastening holes, respectively on both sides opposite the fastening holes. Depending on the chosen screw or bush, in particular a conical sink for receiving the screw head and a cylindrical sink for pressing in the inner thread bush can be provided, i.e. only in this respect the clamping plate is preferably not symmetrical with respect to the center plane parallel to the main plane with its fastening holes, but otherwise preferably symmetrical with respect to all three center planes.

[0044] Preferably, different lengths of elongated screws, in particular three or more different lengths, are provided in the construction kit or system. Thus, by matching selection of screws, the height between two clamping plates that can be used can be selected.

[0045] These two aspects can be particularly advantageously combined with one another, i.e. the end fastening device preferably has an end link of a support chain and / or a link holding element according to the first aspect and likewise a clamping plate according to the second aspect.

[0046] All the features described above for the individual components can also be advantageously applied in combination in a building block or construction kit manner. BRIEF DESCRIPTION OF DRAWINGS

[0056] Figures 1A-1B An embodiment of a dynamic, reciprocating conduit guide device 1 is shown, used to supply conduits 8, for example, for the supply of current and data in machinery. The conduit guide device 1 is linearly movable, forming a movable upper segment 1A, a stationary lower segment 1B, and a moving turning arc 1C between them. The upper segment 1A is movable in the longitudinal direction L of the conduit guide device 1. The turning arc 1C has a predetermined turning radius, or bending radius, about the lateral direction Q and perpendicular to the longitudinal direction L. Figure 1A In this design, the pipeline guiding device 1 comprises two flexible sheaths 2 extending longitudinally along the longitudinal direction L, nested one on top of the other. However, the spatial orientation is arbitrary, and the pipeline guiding device 1 can also move vertically, for example. Each sheath 2 is implemented as a flexible tube as a whole, particularly through suitable configuration and / or material selection, to allow reversible flexible bending of the turning arc 1C with minimal force expenditure and to follow the movement of the movable joint or carrier with minimal resistance.

[0057] Each dustproof sheath 2 (also referred to as a "pod") is specifically dustproof and primarily serves to prevent the escape of particles (especially those inevitably generated due to wear of tubing and / or support chains). The configuration of the tubular sheath 2 can be chosen, for example, as described in DE 20 2019 103 276 U1 (therefore referring to Figures 9-10), the teachings of which are introduced here for the sake of brevity. Other tubular sheaths 2 can also be used, such as the tubular sheaths in the prior art mentioned at the beginning.

[0058] Figure 1ATwo end fastening devices 10 are also shown, which are arranged on the end of the line guide 1, respectively. The line guide 1 is attached and fastened by means of the end fastening devices 10 on one of two attachment sites, which are movable relative to each other, for example on a machine or a device (not shown), respectively. Figure 1A An end fastening device according to DE 20 2019 103 276 U1 (see Figures 13A-13D there) is shown. In the following, the preferred, inventive embodiment of the end fastening device is further explained with regard to Figures 2-8, but not exclusively Figure 1A the end fastening device in Figure 1.

[0059] Figure 1B A possible internal division of one of the two casings 2 is shown purely exemplarily in a cross section perpendicular to the longitudinal direction L. The casing 2 can consist of for example a plurality of individual casing units (not shown) made of plastic or be formed as a one-piece hose with a plurality of passages as receiving portions 7. In Figure 1B In Figure 1, the casing 2 has exemplarily five passage-like receiving portions 7 for one or a plurality of supply lines 8 or line bundles and two support chains 9 in the outer receiving portions, which predefine the radius of the deflection arc 1C and support the unsupported length of the upper section 1A that is moved out. The casing 2 is made of a soft, elastomeric plastic, in particular a thermoplastic (e.g. PE, PU, TPU, PTFE, expanded PTFE, PP or similar) and has a cross section that remains constant throughout its length perpendicular to the longitudinal direction L. The casing 2 can be manufactured inexpensively as a cord product in suitable plastic extrusion technology and cut to suitable lengths, for example lengths of approximately 100 mm to approximately 1500 mm. All receiving portions 7 within the casing 2 are spatially separated from each other and arranged side by side in the transverse direction Q. The casing 2 dust-tightly surrounds the lines 8 or support chains 9 over the longitudinal extension and thus avoids the escape of particles, for example due to abrasion or wear.

[0060] Figures 2A-2B A particularly preferred embodiment of the end fastening device 20 according to the application is shown. The end fastening device 20 can be used on both ends of the line guide 1. The end fastening device has a plurality of identically configured clamping plates 210, which are manufactured in Figures 2A-2B in Figure 1 as essentially flat rectangular plates, which consist of metal, for example of an aluminum extruded profile. The clamping plates 210 form a main face 22 for exerting a clamping force on each side and have their main direction H perpendicular to the longitudinal direction L of the casing 2 (see Figure 1Aarranged in the manner of a matrix, the main direction of which corresponds to the longitudinal extension of the clamping plates 210. All clamping plates 210 are identically configured and have two long end sides 211 in the main direction H and two short, narrow sides 212, transverse to which the lines 8 are routed.

[0061] Figures 2A-2B The end fastening device 20 in each layer is configured in multiple layers for a plurality of casings 2 stacked one above the other and comprises in each layer a plurality of different types of modular tension relief elements 23A, 23B, 23C, 23D, etc. In each of the exemplary four layers, identical tension relief elements 23A, 23B, 23C or 23D, respectively, are arranged in pairs opposite one another between two clamping plates 210. The tension relief elements 23A, 23B, 23C, 23D each have a clamping face 232 for force-lockingly holding one or more lines 8 (see Figure 1B ) in the respective channel-like receptacle 7 together with the casing 2. The tension relief elements 23A, 23B, 23C, 23D are modular and configured for arrangement in rows opposite one another between the mutually facing main faces 22 of the clamping plates 210.

[0062] Each of the identically configured clamping plates 210 has a holding region 213 for the tension relief elements 23A, 23B, 23C, 23D, etc., respectively, which holds these tension relief elements on the respective clamping plate 210 against displacement in the longitudinal direction L. As best seen in Figures 2B-2B , the clamping plates 210 for this purpose each have on their long end sides 211 projecting holding regions 213 facing away from one another, which have here an end-side profiled cross section 220, which in cross section or side view has a back cut, wherein, Figures 2A-2B the back cut in each case is embodied by a substantially U-shaped or else constant in the main direction through-going holding groove 221 or recess on the end side 211. The holding groove 221 is here embodied symmetrically with respect to two central planes perpendicular to and parallel to the main face 22 and has a rounded rectangular cross section having substantially half the constructional height of the clamping plate 210.

[0063] The different tension relief elements 23A, 23B, 23C, 23D, etc. each have two connection regions 230, which here have a claw-shaped cross section with respect to the main direction H, which is configured for form-locking engagement from behind into the back cut or holding groove 221 of the profiled cross section 220 of the holding region 213 of the clamping plate 210, i.e. into the end-side holding groove 221, as best seen in Figures 2A-2BThe connection regions 230 are embodied on both end sides as identically configured, symmetrical claws, respectively, wherein each claw of the connection region 230 does not completely occupy half of the free height of the holding groove 221 of the end side, so that on both sides of each clamping plate 210 the tensile force reduction element 23A, 23B, 23C, 23D can be fitted into the profile cross section 220 of the holding region 213 with the respective connection region 230.

[0064] Between the opposing connection regions 230, on the back side of the tensile force reduction element 23A, 23B, 23C, 23D, a receiving portion 231 is configured which receives approximately half of the cross section of the respectively assigned clamping plate 210. Thus, one and the same clamping plate 210 can be used for two successive layers of the sleeve 2, as shown in Figure 2A the three clamping plates 210 built in in the height direction. The tensile force reduction elements 23A, 23B, 23C, 23D have different clamping faces and essentially the same base face in order to be used modularly. The tensile force reduction elements 23A, 23B, 23C, 23D can be made of the same soft elastic and wear-resistant plastic as the sleeve 2 (see above).

[0065] By the configuration of the connection regions 230 which are fitted into one or more undercut portions of the clamping plate 210 in a form-locked manner, the tensile force reduction elements 23A, 23B, 23C, 23D are held in a fall-preventing manner on the respective clamping plate 210 not only in the longitudinal direction L, but also in a direction perpendicular to the main face 22.

[0066] In Figures 2A-2B is also shown a special fastening element 24 for supporting the chain 9, which fastens the chain 9 on the end fastening device 20 in the longitudinal direction L. The fastening element 24 has identically configured connection regions 230 and receiving portions 231 (not designated) on its back side. The respective content also applies to the additional spacing holders 25 in the upper two layers in Figures 2A-2B These spacing holders 25 allow a lateral displacement in the transverse direction Q between the opposing tensile force reduction elements 23A, so that two upper and lower stacked sleeves (as shown in Figure 1A ) can be jointly fastened between two clamping plates 210 in the upper two layers, respectively. Like the fastening elements 24, the spacing holders 25 also have the same claws as the connection regions 230 in the cross section for holding on the clamping plates 210. Thus, the fastening elements 24 and the spacing holders 25 are also reliably held and fastenable on the clamping plates 210 in the longitudinal direction L and perpendicular to the main face 22.

[0067] As Figures 2A-2BIt is further shown that the profile cross-section 220 leads to the outside, i.e. is open to the side, on both sides of the short, narrow side 212. The profile cross-section 220 remains constant throughout its length in the main direction H or, respectively, through the narrow side 212. Thereby, the tension relief elements 23A, 23B, 23C, 23D, the fastening elements 24 and the distance holders 25 can be selectively modularly or, respectively, as required, arranged on the clamping plate and positioned in the respective position by pushing in along the main direction H.

[0068] Furthermore, Figure 2B Exemplarily, a toothed clamping face 232 is shown, for force-lockingly holding the pipeline 8 together with the jacket 2 on the tension relief element 23A (in the upper layer). Here, the clamping face 232 has a rack or, respectively, comb of teeth extending in the longitudinal direction L, which alternately protrude between recesses, which allows a certain deformability for adapting to different diameters of the pipeline 8 and at the same time achieves a good frictional locking. The clamping face 232 is exemplarily only briefly described. A planar configuration is also possible, for example in the case of the tension relief elements 23B, 23C, 23D, which differ, inter alia, in the different structural height or, respectively, depth of the respective clamping face. In addition, it is also possible to use tension relief elements with concave clamping faces or concave / convex clamping faces. These also have a connection region 230 which cooperates with the holding region 213.

[0069] As Figures 2A-2B It is further shown that the end fastening device 20 has, according to a further aspect, two plate connectors 240A; 240B arranged as separate components between the lateral end regions 214 of the clamping plate 210, respectively, to respectively grip and connect two clamping plates 210 in pairs on one of the two lateral end regions 214, respectively. For this purpose, each plate connector 240A, 240B has two opposite clamp regions 242, which, according to Figures 2A-2B In its construction, the plate connector 240A, 240B corresponds to the claw-like connection region 230 of the tension relief elements 23A...23D, i.e. has two end-side claws facing into one another. However, the plate connector 240A, 240B respectively has a respective clamp region 242 on its upper side and lower side, respectively, for connecting with the two clamping plates 210. By means of the plate connector 240A, 240B, the clamping plates 210 are respectively connected to one another in pairs and held parallel to one another at a predetermined distance. For this purpose, the opposite clamp regions 242 respectively engage at least form-locked into the end-side holding grooves 221 of the clamping plates 210 in pairs, similar to the connection region 230. From the Figures 2A-2BThe embodiments illustrate two types of board connectors 240A and 240B, differing only in their structural height, allowing adjustment of the free space between the opposing tension-reducing elements 23A…23D by selecting board connectors 240A and 240B. Identical board connectors 240A or 240B are used between the two clamping plates 210 at their respective end regions 214. These board connectors are also capable of being pushed in laterally in the main direction H and can be released. Board connectors 240A and 240B have a block-shaped support 243, which is constructed of a solid material, particularly a fixed-shape, inelastic plastic such as fiber-reinforced polyamide. The support 243 has vertical spacing retainers for pre-setting the vertical spacing between the clamping plates 210. The main difference between board connectors 240A and 240B lies in the structural height of the support 243, while they share the same construction in other respects, particularly the identical construction of their vertically and horizontally symmetrical clamping areas 242. Board connectors 240A and 240B may have a concave recess on one side (for receiving space for the sheath).

[0070] Board connectors 240A and 240B each have three through holes 245 distributed in the longitudinal direction L, arranged in the same manner in their support bodies 243, for threaded connection by screws 250. The through holes 245 are arranged to mate with the corresponding through holes, or fastening holes 215, of the screws 250 in the clamping plate 210. Two external screws 250 in the end region 214 can be used for lateral fixing of the assembled end fastening devices 20; 20', as shown in... Figure 2A As can be seen in the image. For this purpose, threaded bushings can be driven into the corresponding fastening holes 215 on the lower side of the clamping plate 210, or nuts can be used. The through holes 215, 245 in the middle can be used to fasten the end fastening devices 20; 20' to the attachment part, that is, to the fixing point or the drive member (not shown).

[0071] As by Figures 2A-2B It can also be seen that the connection area 230 of the tension-reducing elements 23A...23D, the fastening element 24, and the spacing retainer 25 also serves as an edge protection part on the end side 211 of the clamping plate 210, so that the pipeline 8 cannot contact the end side 211 of the clamping plate 210.

[0072] Figures 2A-2B A preferred configuration of the clamping plate 310 is shown separately in more detail. The clamping plate 310 corresponds to the clamping plate from... Figure 1A The clamping plate is cut to the required length as a flat rectangular plate, said rectangular plate being made of metal, such as extruded aluminum profiles. Figures 4B(The shorter construction form is shown only as an example.)

[0073] The clamping plate 310 forms one of two large main surfaces 22 facing away from each other on each main side, and its main direction H is perpendicular to the sleeve 2 (see Figures 3A-3B Or, in other words, the support chain is arranged in the form of a longitudinal direction L, which corresponds to the longitudinal extension of the clamping plate 310. Preferably, all clamping plates 310 of the same end fastening device have the same construction (see...). Figures 3A-3C It has two long end sides 311 and two short narrow sides 312 in the main direction H, with the conduit 8 being threaded transversely to the long end sides, and the short narrow sides arranged parallel to the longitudinal direction L. Figures 2A-2B As shown, the clamping plate 310 is configured to have a rectangular base and a flat planar main surface, and thus has a space-saving construction, especially in the case of storage and transportation.

[0074] like Figures 3B-3C As shown more clearly, clamping plate 310 (also as in...) Figures 7A-7D (as in the middle) Each long end side 311 has a retaining groove 321 that is open or accessible in the longitudinal direction. For example, from... Figure 4A As can be seen, both retaining grooves 321 have a generally quadrilateral cross-section that remains constant throughout, extending from one narrow side 312 to the other. Both retaining grooves 321 open laterally, opening at the narrow sides 312. Therefore, retaining elements, such as tension-reducing elements 23A, 23B, 23C, 23D for the ends of conduits, board connectors 240A, 240B, or end-side links (see [link to end-side link]), can be pushed in from both sides. Figures 4A-4B The retaining element is then mounted on the clamping plate 310 by means of tongues 233 (e.g., symmetrical claws with the same construction as the connecting region 230, as described above) that fit into the two retaining grooves 321. Here, the mounted retaining element is form-locked on the clamping plate 310 both in the longitudinal direction L and perpendicular to the main surface 22, so that these retaining elements can be removed or reassembled together with the clamping plate. Furthermore, the retaining element is held in such a way that it can freely shift on the clamping plate 310 in the main direction H.

[0075] Along the longitudinal direction L, three fastening holes 315 are provided on both sides near the narrow side 312, serving as through holes for screws (see...). Figures 2A-2B ).

[0076] Apart from features that are not functionally related, such as markings, the clamping plate 310 is substantially symmetrical with respect to its three main planes, except that the fastening hole 315 is not implemented to be symmetrical with respect to the central plane S1, which is parallel to (spread by directions L and Q) the main plane or flat main plane 22.

[0077] The clamping plate 310 is symmetrical about the central plane S2 perpendicular to the main plane in the transverse direction, and about the central plane S3 perpendicular to the main plane in the longitudinal direction, so that the clamping plate can also be rotated 180° for use.

[0078] Figures 4A-4B Three different board connectors, 240A, 240B, and 240C, are shown, differing in their structural height and other aspects. Figure 4A Description. Board connectors 240A, 240B, and 240C connect clamping plates 210 and 310 to each other parallel to each other at the desired spacing.

[0079] Preferred, such as Figure 4C As shown, the structural kit for the end fastener has at least four extension screws 450C at each corner of the clamping plate 310, in addition to multiple clamping plates.

[0080] Figure 4A Three extension screws, 450A, 450B, and 450C, of ​​different lengths are shown to select the usable height between the two clamping plates to match the structural height of the board connectors 240A, 240B, and 240C. A particularly easy-to-assemble and maintain construction is achieved using extension screws 450A, 450B, and 450C. Figure 4D The longest extension screw 450C is shown as an example. Extension screws 450A, 450B, and 450C can be selectively and modularly connected to each other for axial extension, and for this purpose, each has an external thread 451 and a mating internal thread 452 on its screw head, into which the external thread 451 of the next extension screw 450A, 450B, or 450C can be screwed. Therefore, individual layers, or sleeves 2, can be removed individually along their respective lines without having to loosen all the lower layers. This significantly simplifies maintenance. Furthermore, the end fasteners can be easily and modularly extended or also reduced by one layer in this manner without loosening all the clamping plates 310.

[0081] On the lowest clamping plate 310 (see...) Figures 5A-5C A press-fit internal threaded bushing 46 is provided, preferably with an internal thread 462 that matches the external thread 451 of extension screws 450A, 450B, and 450C. For example... Figures 2A-2BAs shown, the internally threaded bushing 460 has an internally threaded bushing. To tighten or loosen the threaded connection, the extension screws 450A, 450B, and 450C have a built-in internal hexagonal screw 453 on the screw head for the corresponding tool, preferably axially drilled in such a way as to extend into the internal thread 452.

[0082] The clamping plate 310 has a tapered recess 317 for receiving the screw heads and a cylindrical recess 318 for receiving the head or edge of the internal threaded bushing 460, which are opposite each other on both sides in order to sink the heads of the extension screws 450A, 450B, 450C into the two corner side fastening holes 315, so that the extension screws 450A, 450B, 450C and the internal threaded bushing 460 do not protrude from the main surface.

[0083] Figures 3A-3C The layer or plane shown is a purely exemplary construction of an end-fastening device, which has according to Figures 1A-1B The two clamping plates 210, for example, have a tension-reducing element 23A and a plate connector 240A, or have Figures 2A-2B Features. Next, another aspect of the invention independent of the above-described features will be described with reference to Figures 5-7, wherein other features correspond to... Figures 1A-1B and Figures 6A-6B Its characteristics.

[0084] This solution involves the end fastening of the support chain 509, or its fixation along the longitudinal direction L on the end fastening device 500, wherein two support chains 509 in the receiving part are exemplarily shown here laterally outward in the sleeve 2, and in the lateral direction H or Q ( Figures 6A-6C The position on the ) can be selected in a modular way depending on the application.

[0085] The support chain 509 extends in the longitudinal direction L from the first end 2A to the second end 2B of the flexible sheath 2 to support the sheath together with the tubing (not shown) guided therein, and if necessary, support one or more layers and segments above it and ensure the predetermined radius of the turning area 1C.

[0086] The support chain 509 is configured with a plurality of identical links 510, which preferably have the configuration of DE 20 2019106 979 U1 or International Patent Application No. PCT / EP2020 / 085861 and are therefore only briefly described here. Each link has corresponding first and second hinge elements configured to pivotally connect two links in a plane substantially perpendicular to the lateral direction. Here, the body of the link has, for example, a hinge retractor 513 in a first region 511, which works in conjunction with a hinge bolt 514 in a second region 512. In the preferred embodiment of DE 20 2019 106 979 U1, the second region 512 having the hinge bolt 514 is received into the receiving portion 515 of the first region 511, wherein the hinge bolt 514 is rotatably engaged in the corresponding hinge receiving portion 513 and does not protrude beyond the sides 520A, 520B of the body of the link. See [reference needed] Figures 6A-6D The hinged connection, having a hinge bolt 514 and a hinge retractor 513, allows the links 510 to swing relative to each other in a defined manner, wherein the swing angle is limited in two directions, as described in DE 20 2019 106 979 U1 or PCT / EP2020 / 085861. However, the invention can be applied to any other comparable support chain. The links 510 are preferably manufactured in a one-piece body made of plastic, for example, by injection molding.

[0087] like Figures 6C-6D As best shown, two locking protrusions 570A and 570B, facing away from each other, are respectively provided on the two end side links, or end links 510A and 510B. These locking protrusions laterally project onto corresponding sides of the outer side 520A or 520B in a direction substantially parallel to the lateral direction Q or H. Here, the locking protrusions 570A and 570B project laterally significantly beyond the hinge bolt 514 and have a significantly larger diameter. Figures 6A-6B In this embodiment, locking protrusions 570A and 570B are formed from the ends of secure metal pins 570, which are pressed seamlessly into the central frame region 516 of the end links 510A and 510B through post-processed lateral openings or lateral drilled holes. Suitable standard components from the mechanical manufacturing field can be used as the metal pins 570. Alternatively, the locking protrusions can also be manufactured as a single piece with the end side links or the main body of the end links 510A and 510B, for example, using a specialized injection molding die; however, post-processing of individual pins allows all links 510 to be manufactured as identical pieces. Figure 5B The image shows a shortened end link 510B, which is shortened by cutting off or removing according to...Figure 5C The second region 512 of the link 510A is provided, which is advantageous depending on the structural length of the link 510 and may relate to the clamping plates 210, 310. Here, but especially for good force introduction, it is also advantageous to provide locking protrusions 570A, 570B, or pins 570, in the region where the longitudinal direction L is centered, especially in the body rumpf or solid material between the end regions 511, 512 of the links 510A, 510B.

[0088] To lock the corresponding support chain 509 in the longitudinal direction L, a pair of identical, opposing link retaining elements 700 and two end fastening devices are respectively provided on the clamping plate 210. See Figures 7A-7D Or rather Figure 5A .

[0089] Link retaining element 700 in Figure 5B-5C Shown in more detail, and having two laterally positioned and laterally opposed retaining recesses 705A and 705B, the retaining recesses are implemented as semi-cylindrical grooves to receive approximately half the cross-section of one of the locking protrusions 570A and 570B in a form-locking manner. Therefore, in order to secure the support chain 509 laterally to the two end fasteners via its end links 510A and 510B, the two link retaining elements 700 are used as identical components in pairs, which simplifies operation and, in particular, simplifies warehouse management and reduces costs through the increased number of components.

[0090] Two lateral locking protrusions 570A and 570B on each end link 510A and 510B respectively engage with corresponding retaining recesses 705A and 705B in the associated link retaining element for locking the support chain 509 in the longitudinal direction L.

[0091] As in ​As can be seen in the exploded view, each of the end-side links 510A and 510B is respectively equipped with a pair of link retaining elements 700, which are placed facing each other and arranged opposite and aligned about a plane parallel to the main surface 22 of the clamping plate 210 (parallel to the longitudinal direction L and the transverse direction Q) so as to receive and, if necessary, clamp the links 510A and 510B between them in the assembled state. For this purpose, each link retaining element 700 has two opposing sidewalls 701A and 701B extending in the longitudinal direction and having a receiving portion 703 between them that faces the main plane and opens in the longitudinal direction L for the end-side links 510A and 510B. The sidewalls 701A and 701B have a top surface 704, which is arranged parallel to the main surface of the clamping plates 210 and 310, or in other words, the plane (opened by the longitudinal direction L and the transverse direction Q), as they are assembled onto the clamping plates 210 and 310.

[0092] Retaining recesses 705A and 705B are respectively provided in one of the sidewalls 701A and 701B, and are open on both sides, especially toward the receiving part 703, and also toward the opposing retaining element 700, or toward the sleeve 2 at the top 704. Therefore, links 510A and 510B can be inserted and removed without tools, that is, the support chain can be loosened and tightened without tools at the end sides of the opposing clamping plates 210 and 310.

[0093] The dimensions of the receiving section 703 are determined such that it preferably accounts for at least 25% to nearly 50% of the structural height of the receiving end side links 510A and 510B, for example... ​ As shown. Preferably, the pair of retaining recesses 705A and 705B, which are respectively formed by opposing retaining recesses, surround the locking protrusions 570A and 570B that work together substantially completely or over almost the entire periphery.

[0094] On the upper surface 704 of the side walls 701A, 701B, there are clamping elements or claw elements for longitudinally securing the sleeve 2 surrounding the support chain 509, so that this, or receiving portion, of the support chain is also secured together. Advantageously, the sleeve is guided until it abuts against the closing wall 706 of the link retaining element 700 at the end side, so that the corresponding receiving portion can be sealed as dustproofly as possible with the assembly of the end fasteners. It is advantageous here that the simple geometry of the link retaining element 700 and the locking protrusions 570A, 570B, without special back cuts and sharp edges, prevents damage to the sleeve when it is clamped between the link retaining element 700 together with the corresponding end links 710A, 710B. The link retaining element 700 is preferably manufactured in one piece of plastic, especially as an injection-molded part.

[0095] The link retaining element 700 has two tongues or claws 721 facing each other at its two longitudinal ends on its back side, opposite to the front side with the receiving portion 703. These tongues or claws, for connection, particularly in the form of a keyway connection, cooperate with corresponding end-face retaining grooves in two opposing end-side retaining grooves 221, 312 (on the clamping plates 210, 310 of the end fasteners). Therefore, to securely fasten the support chain 509, only slight post-processing is required to provide locking protrusions 570A, 570B on the two end links 710A, 710B, and a unique identical part 700 is needed.

[0096] The proposed configuration also has the following particular advantages: the support chain 509, which wears during movement, can be replaced as easily as a pipeline because no special fastening devices, such as vertical screws or pins passing through the support chain and clamping plates, are required. The loosening of the two clamping plates 210, 310 of one layer also loosens the longitudinal lock, or fastening, of the support chain, and conversely, this longitudinal lock, or fastening, is established together during connection, significantly simplifying assembly and maintenance.
