Definitions
- the invention relates generally to the field of energy guiding chains for the protected, dynamic guidance of lines such as cables, hoses and the like.
- Energy guiding chains are typically constructed from pivotably connected chain links which each have two side plates spaced from one another transversely to the longitudinal extension of the energy guiding chain. At least in the case of some of the chain links, these are stably connected to one another by two transverse webs and define an inner receiving space or guide channel for the lines to be guided.
- Energy guiding chains typically have two ends that can move relative to one another and are each connected to a connection area. A typical energy chain moves between the
- connection areas back and forth with the formation of two strands and a deflection arch between the strands. In the deflection curve, the direction of the respective strand is reversed.
- the invention relates specifically to a crossbar (also called a traverse) for a chain link of an energy guiding chain, which is used to connect side plates and to mount and hold separators.
- a crossbar also called a traverse
- Such a transverse web usually has an elongated base body made of plastic and, at each of its longitudinal ends, a connecting area for fastening to one of the side flaps.
- the side flaps and the crossbars delimit the receiving space of the chain link transversely to the longitudinal direction of the guided lines.
- the receiving space of the chain link can be divided up by dividers and shelves so that the lines can be routed in an orderly manner and do not get tangled.
- separating webs are typically installed between the two transverse webs of a chain link parallel to the side plates and are held on at least one of the transverse webs.
- the base body of the transverse web is usually plate-like and has two main sides, two long narrow sides extending in the longitudinal direction of the transverse web and two short sides extending in the width direction of the transverse web.
- Each of the narrow sides extending in the longitudinal direction of the transverse web usually has a holding device for holding separating webs. Separators can for their part hold shelves parallel to the crossbars, for example by attaching them to separators or through openings in separators through which shelves can extend.
- EP 1564 438 A2 does not disclose how the chain links are built up, how different parts of the internal structure are connected to one another, in particular in view of an additional layer on their surfaces.
- a coating process is technically complex, for example to the effect that a coating of the same quality results in each of the various series.
- DE 102012 106 400 A1 discloses transverse webs which have separate elastically deformable tubular elements which are rotatably mounted on the transverse webs and can act to reduce the wear and tear on the guided lines.
- the tubular elements protrude in the radial direction into the receiving space of the chain link and thereby take up a relatively large amount of space in the interior, which is therefore not available for the lines to be routed.
- dividers can only be attached between the pipe elements, i.e. the internal division is restricted.
- WO 99/054642 discloses a transverse web for a typical chain link of an energy guiding chain, which connects two side parts to one another and has an elongated base body.
- the base body of the transverse web according to WO 99/054642 has two narrow sides which extend in the longitudinal direction of the transverse web and each have a holding groove which is suitable for holding separating webs.
- the crossbar according to WO 99/054642 is equipped with rollers on the inside in order to allow the cables to unroll on the crossbars. Unrolling reduces the friction, but a structurally complex design with a mounting of the rotatable rollers on the crosspiece is necessary for this. This solution also noticeably reduces the available height in the interior.
- the solution should allow a flexible internal division of the chain links, be compatible with existing designs and / or be optionally retrofittable.
- a line-friendly layer made of a second plastic is provided, which at least with regard to the composition, but in particular with regard to the base material, for example the selected base polymer, different from the first plastic, the plastic of the base body, is selected and serves to reduce abrasion during relative movement between a guided line and the crosspiece.
- the line-friendly layer extends from one narrow side to the other narrow side of the base body. According to the invention, the layer covers the inside of the base body between the narrow sides at least predominantly, preferably essentially completely, but leaves both holding devices uncovered, ie the holding device on one The narrow side and the holding device on the other narrow side.
- the respective holding device remains accessible for form-fitting and / or force-fitting connection with separating webs.
- the holding area of the holding device on the respective narrow side of the base body preferably remains uncovered in the longitudinal direction of the transverse web over its entire effective length and is therefore freely accessible.
- the second plastic differs from the first plastic, the plastic of the base body, in particular with regard to sliding properties such as
- the (sliding) coefficient of friction of the second plastic is lower than the (sliding) coefficient of friction of the first plastic under corresponding test conditions, in particular with respect to the outer material of the lines to be routed.
- the reduction of abrasion in the event of relative movement between a line and the transverse web is brought about in particular by reduced sliding friction ("sliding which is gentle on the line") of the lines guided on the transverse web.
- the line-friendly layer is particularly preferred as a coherent layer, in particular in one piece made of the same material, in particular as a separate or retrofittable molded part or component.
- the line-friendly layer can remain immobile relative to the surface of the base body when used as intended.
- the material thickness of the additional line-friendly layer can be significantly less than that of the base body, which forms the actual structural component.
- the holding device of the transverse web for holding separating webs can, for example, comprise a row of teeth and / or a holding groove on the respective narrow side for a positive connection with complementarily configured separating webs.
- the line-friendly layer does not extend over the holding devices, so that the respective holding device remains accessible for connecting to separating webs. Nevertheless, the line-friendly layer can form edge protection, which covers and defuses interfering edges of the base body.
- the line-friendly layer extends continuously or uninterrupted in the longitudinal direction between the longitudinal ends or connection areas and in the width direction from one narrow side to the other narrow side and thus essentially completely extends the inside of the base body covered, in particular over the entire area continuously in the width direction and in the longitudinal direction of the crossbar.
- the width direction of the transverse web corresponds to the longitudinal extension of a chain link in the chain direction or the guided lines; the longitudinal direction of the crosspiece corresponds to the transverse direction of a chain link (not the chain).
- the line-protecting layer can preferably be produced as a separate body or as a molded part and connected to the base body, in particular be detachably connected to the base body.
- This embodiment allows the transverse webs to be retrofitted with the line-friendly layer and, if necessary, also an exchange of the line-friendly layer, for example in the event of wear.
- the line-friendly layer can preferably be an add-on component, in particular for retrofitting as required.
- the line-friendly layer can be attached to the base body in a form-fitting and / or force-fitting manner, in particular by means of a latching connection, in particular it can be detachably fastened.
- the cable-protecting layer and the base body can in particular have locking elements that match each other, e.g. clip connectors for clipping the cable-protecting layer onto the base body.
- the line-friendly layer and the base body can be designed in such a way that they allow the line-friendly layer to be snapped onto the base body transversely to the main plane. In the case of plastics, simply designed locking means that allow manufacturing tolerances allow the cable-friendly layer to be quickly attached to the base body, even without complex alignment of the two parts with one another.
- the transverse web and the line-friendly layer can be produced as separate parts, in particular as injection molded parts.
- the line-friendly layer can preferably rest closely or flush against the inside of the base body, and in particular be designed as a molded part with a shape complementary to the surface profile of the inside.

- Snap connection area or latch connection area of the line-friendly layer interact with one of the holding devices, which may not be required for connecting to separating webs.
- the interaction of a fastening area of the base body with a snap connection area or snap connection area of the line-protecting layer can produce, for example, a snap connection or a clip connection.
- the fastening area of the base body can comprise a profile groove or a recess on the inside surface of the base body, for receiving a complementary projection in each case, which is on the line-protecting layer as a
- Snap connection area or locking connection area is formed, wherein the projection comprises at least one acting in the manner of a barb or snap hook area.
- a latching connection with the aid of a hook area can allow the cable-protecting layer to be easily connected to the base body, which is secure against displacement and in which the two parts of the crossbar are held immovable relative to one another during operation of the energy guiding chain.
- the recess for the projection can extend like a groove in the longitudinal direction of the transverse web and be positioned as desired relative to the transverse direction of the transverse web.
- the projection can extend in the longitudinal direction over part of the length of the transverse web and / or several projections can be provided distributed along the longitudinal direction, which interact with corresponding recesses, e.g. an elongated groove or separate recesses on the inside of the base body.
- the projections can also be arranged on the base body and the corresponding recesses on the line-protecting layer, but this is not preferred, since the transverse webs or base body should also be able to be used without a line-protecting layer.
- two end-side fastening areas for fastening the line-friendly layer to the base body are designed as a longitudinal groove along one narrow side of the base body in each case. These can be used to engage through a respective edge area of the line-friendly layer.

In this way, the line-friendly layer can engage with the respective edge area in the corresponding longitudinal groove.
- the line-friendly layer can thus be snapped onto the base body, the edge areas of which snap into the longitudinal groove on the base body.
- An advantage of this embodiment is the robust fastening, for which no additional fastening means are necessary.
- the edge areas can inherently offer edge protection, for example by means of a rounded outer contour.
- the line-protecting layer can also be integrally and / or cohesively connected to the base body, in particular injection molded onto the base body.
- a crossbar can be produced, for example, using a suitable two-component (2K) injection molding technique, or, for example, by subsequently injecting the second plastic onto a separately produced base body.
- Each holding device of the base body can each include a row of teeth on the respective narrow side for a form-fitting connection with complementarily designed separating webs, with teeth that protrude in particular in the width direction of the cross web.
- Each tooth can have a dimension in the vertical direction of the transverse web which is greater than a dimension of the tooth in the longitudinal direction of the transverse web.
- each holding device of the base body can have a holding groove on the respective Include narrow side of the base body for a form-fitting and / or force-fitting fastening or connection with complementarily configured separating webs, wherein the retaining groove can extend in the longitudinal direction of the transverse web.
- the cable-protecting layer is preferably only provided on the inside of the base body and between the narrow sides of the base body, so that an outside opposite the inside, which faces away from the receiving space of the chain link in the intended state of a crossbar built into a chain link, is essentially free of the cable-protecting layer or is not covered by the cable-friendly layer.
- This preferred embodiment saves material, since the line-friendly layer in this embodiment is only provided on the inside of the base body, on which the lines to be routed can come into contact with the transverse web.
- the one-sided attachment of the line-friendly layer can be implemented in particular by fastening areas for attaching the line-friendly layer to the base body, which, as described above, allow a snap-in connection or snap connection so that, despite the one-sided attachment, an immovable fixed connection is possible that is not possible when in contact with guided lines slipped.
- the line-protecting layer can preferably comprise a material which, compared to the base body, has a wear-reducing effect, in particular a friction-reducing effect.

- the material of the line-protecting layer can, for example, be a different thermoplastic and be based on a different polymer than the plastic of the base body. While the base body can be made from a typical polyamide, possibly reinforced or provided with additives, the additional line-friendly layer can be made from a polyethylene or a polypropylene or the like.
- the plastic of the line-friendly layer can in particular have a different hardness and / or rigidity than the material of the base body, so that an abrasion-reducing effect for protecting the routed lines is achieved.
- the second plastic of the line-friendly layer comprises or consists of a base material or a base polymer, which is particularly preferably softer or has a lower hardness (SHORE hardness D or hardness value according to VDI / VDE 2616) than the plastic (base material) of the main body of the crosspiece. In this case, it can optionally be more flexible than the plastic of the base body.

- the transverse webs 12 are releasably attached to the side flaps 11 by means of fastening areas at the end, for example by means of clamping receptacles on horns (not shown) of the side flaps 11.
- the side tabs 11 and transverse webs 12 delimit a receiving space 14 for the lines 16, 17.
- Energy guiding chain 1 is known and can be of any desired type, for example with cranked side plates or alternating inner and outer plates as side plates 11.
- two-part chain links in which the two side plates 11 and a transverse web 12 are made from one piece, ie are made in one piece, are also possible only the other transverse web 12 is detachable (not shown).
- the separating webs 20 have two end regions in the direction of the height h, a head part 22 and a foot part 24, and can, for example, at least at one of the end regions the foot part 24, be attached to the narrow sides 23 of the crossbars 12 at a selectable position in the direction of the width q of the receiving space 14 or in the direction of the length of the crossbar 12, for example by a latching connection.
- the transverse webs 12 are in any case secured in the longitudinal direction of the energy guiding chain 1 or in the direction of the width B of the transverse web.
- the transverse floors 18 are each in horizontally continuous through openings 32 (cf.

For each chain link 10 with cross webs 12, a similar internal division of the Receiving space 14 in favor of the lines 16, 17 are made. Separating webs 20 and transverse floors 18 should therefore be provided at regular intervals and in an identical arrangement on every nth chain link 10 in order to divide the receiving space 14 into constant compartments or compartments 19 for the orderly and better protected routing of the lines 16, 17.
- FIGS. 2A-2C show an embodiment of the internal division of a chain link 10 in partial view.
- the separating web 220 has a retaining clip 234 each on the head part 222 and on the foot part 224.
- the retaining clips 234 on the head and foot parts 22, 224 are designed to be identical to one another.
- the separating web 220 is, as FIG. 2A shows, inserted between two identical transverse webs 212, the Hold retaining clips 234 on the head and foot parts of the separating web on the narrow sides 223 of the cross webs.
- Each transverse web 212 is elongated and plate-like and, in the example shown, has a toothed strip or strip-like row of teeth 240 on each of its two longer narrow sides 223, which is designed for a form-fitting connection with complementarily designed separating webs 220.
- the outer contour of the narrow sides 223 each forms a row of teeth 240 with teeth 241 which protrude outward in the width direction B of the transverse web 212 and are spaced from one another by tooth gaps 242.
- a multiplicity of identically designed teeth 241 and tooth gaps 242 are provided in an alternating and uniform manner along a predominant part of the longitudinal extent of the narrow sides 223.
- the teeth 241 and tooth gaps 242 each have a rounded profile on the front side.
- Each tooth 241 has a dimension in the height direction H of the transverse web 212, which is greater than its dimension in the longitudinal direction Q of the transverse web 212, and is, for example, 7 mm. This dimension of the tooth 241 in the height direction H of the transverse web 212 is also larger than the dimension of the tooth in the width direction B of the transverse web 212. This results in a smooth-running and at the same time tilt-stable plug connection.
- the retaining clip 234 has two opposing retaining extensions 250 in the direction of the width of the separating web, which are designed to be complementary to the rows of teeth 240 for holding on the narrow sides 223 of a transverse web 212.
- the distance between the holding extensions 250 of a holding clip 234 from one another corresponds to the width of the transverse web 212.
- the holding extensions 250 have in the depicted Embodiment in each case a pair of tooth projections 251.
- the tooth projections 251 are designed to be positively inserted into the toothed strip or row of teeth 240, here in two successive tooth gaps 242.
- the end region of the holding extension 250 is here, for example, U-shaped in cross section.
- the dimension of the tooth projections 251 in the direction of the separating web width corresponds to the depth of the tooth gaps 242.
- the dimension of the tooth projections 351 in the height direction of the separating web 320 is, for example, approximately 5 mm in the illustrated embodiment.
- transverse base 218, which is plate-like and has a cross-section that matches the through opening 26 of the separating web 220.
- the transverse base 218 has a toothing 227 on one of its long narrow sides for interacting with the latching cam 28 of the through opening 26.
- FIG. 3 shows, in a side view of the narrow sides, an embodiment of the transverse web 312, which likewise has the two toothed strips for a separating web 220.
- the elongated base body 325 is made of a first plastic, for example a reinforced polyamide, in order to provide robust connecting areas 361A, 361B at each of its longitudinal ends, by means of which the transverse web 312 is connected to the side flaps 11.
- a first plastic for example a reinforced polyamide
- the crosspiece 312 can be manufactured, for example, as a 2K injection-molded part.
- the line-protecting layer 365 covers the entire surface of the base body 325 continuously in the longitudinal direction Q of the crossbar between the longitudinal ends and in the width direction B of the crossbar from one narrow side 323 to the other narrow side, so that the toothing protrudes outward only on the front side (FIG. 2). The toothing thus remains accessible and is not covered by the line-protecting layer 365.
- FIGS. 4A-4B and 5A-5B show further exemplary embodiments of the transverse web 412, 512, in which the cable-protecting layer 465, 565, however, is produced as a separate molded part.
- the line-protecting layer 465, 565 can be produced from a material with friction-reducing properties in an injection molding process, but is detachably connected to the base body 425, 525.
- the base body 425, 525 is made of a fiber-reinforced polyamide
- the cable-protecting layer 465, 565 is made of a softer material, e.g. with a lower Shore D hardness than the material of the base body.
- a polyethylene (PE) or HMWPE is preferred, with PTFE as an additive to improve sliding and optionally with glass fiber reinforcement.
- the line-friendly layer can also be made of UHMWPE with PTFE or with dispersed waxes and / or oils to improve tribological properties and, if necessary, with additional reinforcement from glass spheres, glass fibers, carbon fibers, aramid and / or other fillers. These materials can also be used to produce the line-friendly layer according to the exemplary embodiment in FIG.
- the Line-friendly layer 465, 565 attached on one side to the base body 425, 525 of the crossbar 412, 512, namely only on the inside 462, 562 of the base body 425, 525.
- the line-friendly layer 465, 565 extends essentially from one to the other long Narrow side 423, 523 and from one to the other longitudinal end of the base body.
- the inner side 462, 562 of the base body 425, 525 is thus largely covered or covered by the line-protecting layer 465, 565. This ensures that when the crossbar 412, 512 is installed as intended in a chain link 10 of an energy guiding chain 1, the guided lines come into contact with the line-protecting layer 465, 565 and not with the base body 425, 525.
- the transverse web 412 as a holding device for holding the separating webs has a holding groove 442 and a row of teeth 440 in the holding groove 442 on each narrow side 423 extending in the longitudinal direction Q of the transverse web.
- the cable-protecting layer 465 covers the inside of the base body, but not the narrow sides 423, which remain uncovered, so that the retaining groove 442 and the row of teeth 440 are available for connection with separators along their entire length.
- Optional partitions for internal division can thus be attached to the transverse web 412 at any position along the longitudinal extension of the transverse web 412.
- the line-protecting layer 465 is fastened to the base body 425 by a snap connection or a latching connection.
- the line-protecting layer 465 has at least one projection arranged in the middle (with respect to the width direction B of the transverse web 412) 472 on.
- the projection 472 can extend like a rib in the longitudinal direction Q of the transverse web 412, or distributed individual latching pins can be provided.
- the projection 472 has a double snap hook or barbed hook 474 on both sides.
- the base body 425 for its part has a profile groove 470 or latching receptacles 470, the cross section of which corresponds to the cross section of the projection 472.
- the cable-protecting layer 465 can, for example, be pressed manually onto the inside 462 of the base body 425 in the direction transverse to the main plane of the base body 425, so that the projection 472 with the snap hook 474 engages in the profile groove 470.
- the removal of the line-protecting layer 465 from the base body 425 should require significantly more force. This ensures that the cable-protecting layer 465 cannot be detached from the base body 425 when the energy guiding chain 1 is operated as intended and is not displaced relative to the surface of the base body 425, although it is only attached to the crosspiece 412 on the inside.
- a profile groove 470 extends from one to the other longitudinal end or short end face of the base body 425 and is open at the end to the short end faces, so that the line-friendly layer 462 can also be pushed onto the base body 425 from the short end faces so that with of the position 462, the projection 472 is pushed in the longitudinal direction Q of the transverse web into the profile groove 470 parallel to the main plane of the base body. In this way, if necessary, removal of the line-protecting layer 462, for example in the event of excessive wear, from the base body 425 can only be permitted when the transverse web 412 has been removed from the chain link 10.
- FIGS. 5A-5B show a further exemplary embodiment in which the transverse web 512 has a row of teeth 540 on its base body 525 as a holding device for holding the separating webs.
- the teeth protrude from the main plane of the base body 525 in the direction of the height H of the transverse web 512. It is also possible for the teeth to protrude in the direction of width B of the transverse web, as in FIGS. 3A-3C.
- the base body 525 also has a longitudinal groove 570 along its long narrow sides 523, which serves as a fastening area for fastening the line-protecting layer 565.
- the line-protecting layer 565 is designed here like a shell and, in turn, has edge regions 572 running along its longitudinal extent, which interact as snap connection regions with a respectively assigned, additional longitudinal groove 570 of the base body 525.
- the line-protecting layer 565 can be manually pressed onto the base body 525 from its inside 562 and snapped on.
- the edge areas 572 of the line-protecting layer 565 each have a C-shaped cross-section transverse to the longitudinal extent, so that when the line-protecting layer 565 is snapped onto the base body, the respective edge area 572 engages in the corresponding longitudinal groove 570 and the line-protecting layer 565 can fall off or slip off Base body 525 prevented during operation of the energy chain 1.
- the cable-protecting layer 565 lies tightly and without gaps or flush against the inside 562 of the base body 525.
- the narrow sides 523 and the outer side 564 of the base body 525 remain free or uncovered, so that the rows of teeth 540 are available for connection with separating webs along their entire length.
- a snap or latching connection is established between the snap or latching connection areas of the line-protecting layer 462, 562 and the corresponding fastening areas 470, 570 of the base body.
- fastening areas 470, 570 are provided on the base body, spatially separated from the holding devices for the separating webs (row of teeth 440, holding groove 442). Thus, all existing holding devices for connecting to separators are kept free.
- the transverse web has several redundant holding devices for separating webs on each narrow side of the base body, for example both a groove and a row of teeth, or two parallel grooves which run at a distance from one another in the width direction B of the transverse web, with one
- Holding device is closer to the corresponding narrow side and runs along this.
- the line-friendly layer can be snapped onto the base body in such a way that the grooves also act as fastening areas with the snap connection areas of the line-friendly layer
