    [0001] The present invention relates, in general, to a current conducting energy for conducting cables, hoses, or similar components. The invention especially relates to an energy-carrying chain with several links which form two sections of links which are parallel and interconnected by separate beams. In this case, the links can be angled reciprocally through an articulated connection.
    [0002] An energy-conducting current of this kind became known, for example, from the German patent DE 35 31 066 of the supplicant. In energy-conducting chains, according to the principle of document DE 35 31 066, the articulated connection will be formed between adjacent links by means of swivel pins, that is, swivel stays, arranged in the middle of the link, and corresponding cutouts. Although these energy-conducting chains have passed very well, they have the disadvantage that the articulated connection of swivel pins and corresponding assembly, due to friction, despite the long service life is inevitably subject to certain wear. This wear can result, for example, in a certain formation of residues, which, in general and especially in products under clean space conditions or in the production of food products, is unwanted.
    [0003] A development to reduce wear and scratching in energy conducting currents became known from the international patent application WO 02/086349 of this supplicant. In this case, the articulated connection between adjacent links will be formed by articulated elements elastically deformable in the angulation direction of the chain links. In the energy-carrying chain with very low wear, according to WO 02/086349, in turn, the links in the two sections relative to the main longitudinal projection plane of the energy-carrying current have specular symmetry, that is, the links in one section are mirrored in relation to those in the other section and are therefore differentiated. Thus, these specular symmetry chain links require molds for differentiated injection molding for their production.
    [0004] Nevertheless, many advantages and the successful expansion of energy-conducting currents according to WO 02/086349 it has now been revealed that the differentiated mold, in disadvantageous cases, can result in that due to production tolerances, they can be formed in the two sections of the chain, limitations of different angulations, different clearance and especially different lengths of the section. This is of course undesired, especially in the case of relatively large currents.
    [0005] From the description DE 10 2007 061 296 it became known an energy-conducting current which, to reduce the number of components, uses in certain regions, specular symmetrical shaping modules of several external links, as well as internal links conformed with specular symmetry. In this process, the proposed connection of the modules produced in one piece in the longitudinal direction of the current constitutes a disadvantage. This last action results in differentiated shapes at the ends of the left and right link section, both at the end of the fixed chain and at the end of the moving chain. Even more accentuated, the problem of differentiated ends of the link sections arises in the case of an energy-conducting chain according to the descriptive report DE 10 2008 020 907. There it is proposed that the chain as a whole is constituted by only one similar module to a comb with outer links, transoms and inner links. The mutually offset fitting of these comb-like modules, however, means that the ends to be fixed not only are molded differently, but, in addition, they will be offset in the longitudinal direction in different extensions.
    [0006] Departing from the above-mentioned prior art, the objective of this invention consists, therefore, in a first technical task of proposing an energy-conducting current with the advantages of an articulated connection with reduced wear rate and that even so avoids related differences tolerances between opposite sections of chain, ie links, especially differences in length, are reliably avoided.
    [0007] In an energy-conducting current of this kind and the second preamble of claim 1, this first task, according to the invention, will be solved by the fact that in each link section, in the longitudinal direction of the current, different alternating inner links and outer links. In this case, both the internal links and the external links have a specular symmetrical shape in relation to their vertical central plane that extends perpendicularly to the longitudinal direction. In this way, inner links of identical construction and outer links also of identical construction for detachable assembly can be used in the two link sections, which, considered separately, are produced in the same mould. links of one type that are produced in a mold, especially an injection molding mold will therefore be used in both link sections. As a result, any tolerances in the two sections have identical and symmetrical effects, so that especially no longer differences in length can form. In addition, the solution foresees that the articulated connection between adjacent links is formed by the articulated element with articular symmetry, which has, in particular, opposite end areas which, relative to the vertical central plane, are shaped with specular symmetry. These end areas serve for fixation, that is, interlocking of detachably connected adjacent internal and external links with each other in the longitudinal direction of the chain. As the connection of neighboring links in the longitudinal direction is also continuously shaped in specular symmetry with respect to the height-central plane, sections will be obtained that, as a whole, relative to the central plane of the energy-carrying current, directed in the longitudinal direction, are of specular symmetry . Therefore, both sections, on the left and right side, both at the end of the fixed chain, as well as mobile, always have identical end sections for fastening. In this way, among other things, it is possible to reduce the fastening in a simplified way, as well as the numbers of fastening components needed for only one form of component.
    [0008] The articulated elements can be specially designed as separate components. Alternatively, the articulated elements can also be formed in one of two types of link, namely the inner link or the outer link, so as to protrude from the front face, in particular by injection moulding.
    [0009] Preferably, the articulated element will be arranged in the central longitudinal plane of the links extending in the longitudinal direction. This allows, with a suitable conformation, to integrate the links also rotated around their transverse axis. In a preferred embodiment of this nature, the inner link and the outer link are differentiated in their outline in a side view, so that, according to the arrangement, another shape of the chain curve becomes possible. Especially the internal and external link are differentiated, at least, due to the differentiated conformation of their frontal sides, opposite in the longitudinal direction. These front sides form, in at least one of the types of the two types of differentiated links, stop surfaces that serve to limit both the end position with the greatest angle and also the end position with the smallest angle. For the differentiated limitation, these stop surfaces are asymmetrical with respect to the central longitudinal plane of the link. By disposing the abutting surfaces on the front sides of at least one type of link, a stabilized disposition will be ensured by a greater possible overlap between the internal and external links. Furthermore, the asymmetrical conformation, compared with the longitudinal plane of the chain, makes it possible to adjust the direction of the chain deflection by rotating the asymmetrical link around the transverse axis, this adjustment being as desired.
    [00010] In a preferred embodiment, the link of the second type of link has stop surfaces that cooperate with the asymmetrical stop surfaces on the front sides of the first link and relative to the longitudinal center plane are asymmetric to a lesser extent. A smaller asymmetry, compared to the stop surfaces of the first link, also makes it possible, by inverting the second link around the transverse axis, to obtain an additional adjustment, but which can be adjusted in a more sensitive way, from the rotational limitation or the prestressing.
    [00011] In a preferred embodiment, inner and outer links appear thickened central areas, adjacent in longitudinal direction, as well as sequential thinner overlapping areas in front. These overlapping areas extend beyond the inner and outer links in the longitudinal direction. In this case, the stop surfaces cooperate on the front sides in the first link with corresponding stop surfaces in the thickened central area of the second link. Furthermore, additional third and fourth stop surfaces on the front sides of the second link also preferably cooperate with corresponding stop surfaces in the central area of the first link. By a corresponding doubling of the stop surfaces in the inner and outer areas of the links, the stability of the chain in the two stop positions will be increased.
    [00012] It proves to be advantageous for the stop surfaces to be curved on the front sides of the first link, especially curved in a concave direction. Correspondingly, too, it is advantageous that the mating mating faces of the second link are congruently curved, that is, especially congruently convex. A smooth and adjustable stop will be achieved by the fact that the stop surfaces are curved on the front sides of the first link, as well as the mating action stop surfaces on the second link, with identical curvature, for example, according to a rolling curve. In the version with additional third and fourth stop surfaces, these too will advantageously be curved congruently and in pairs, but with a more accentuated curvature, ie more expressive than the curved stop surfaces on the front sides of the first link. Preferably, the curvatures of the stop surfaces are selected according to a curve format that not only avoids a spatial stop, but enables a successive juxtaposition aiming at greater stability in the stop.
    [00013] To secure the crossmembers, it is especially advantageous that the inner link or the outer links, or both, have their upper and lower narrow side a central cutout in which a retaining rod is provided that projects in the longitudinal direction of the chain. This makes it possible to swivel, similarly to a hinge, the beam on the corresponding link, for example with a hinge provided for this purpose on the beam. In this case, each transom is pivotally fastened on at least one face to the corresponding retaining rod, preferably, however, pivotably on both sides, being locked onto opposite retaining rods. By employing mounting pins of this type or retaining rods on the narrow sides, the annoying projection of inwardly protruding snap-in lugs will be avoided.
    [00014] Preferably, for swivel fixing of conventional and already available crossmembers, a swivel tip will be used as adapter as a separate component. Correspondingly separate swivel tips form another aspect of the invention independent of the solution of the aforementioned problem. In a preferred embodiment, a swivel tip of this type has on one side a hinge-like handle for swiveling mounting on the retaining rod, and on the other side it has a fastening that fits to the crossmembers, for example, two snap-in protrusions opposite in the longitudinal direction of the chain and intended for fastening by means of a quick-fit fastener in the crossmember. This mode furthermore prevents an upward turn when opening the snap-fit closure and, on the other hand, prevents an opening of the snap-fit closure when turning upward.
    [00015] In the use of such swivel tips, it is advantageous to provide means for engaging the retaining rod that cooperate with the swivel tip for penetration in the retracted position or in the closed position or preferably in both positions.
    [00016] In a preferred version, independent of the aforementioned aspects, each articulated element comprises at least a first snap-in means that cooperates with a corresponding second snap-in means in one of the two types of links. In this case, the first and second snap-on means constitute a snap-on connection for retaining one type of link in the other type of link, in transverse direction to the longitudinal direction of the chain.
    [00017] In this preferred mode with quick-fit connection it will be advantageous for saving material when only every second link is joined of the two link sections by means of an upper crossmember and a lower crossmember. The other links, in an intermediate position, can be retained by the quick fit mentioned in the links joined by means of crosspieces. In an especially simple modality, the articulated elements are formed as separate components that interconnect three links, in particular two links, without transoms and an intermediate link with transom. With the hinge elements formed as separate components, it will be preferred when each hinge element has a maximum width that essentially corresponds to the maximum width of the two types of link, however, these do not exceed them. In this way, the maximum possible width without protruding parts will be used. Additionally, the articulated element may have a narrowing in a central region. In this narrowing, the articulated element can be held in the direction of retaining the above-mentioned quick-fit connection next to the central link of the total of three links.
    [00018] According to another independent aspect, it is advantageous that the articulated element has damping extensions that can extend with a free end for damping between stop surfaces of conjugate action of the links. In order not to jeopardize the juxtaposition, that is, the stop of the stop surfaces that cooperate in one of the two types of links, a cutout can be provided for the partial or total fitting of the damper extension.
    [00019] Finally, it will be convenient when that link with greater asymmetry in the lateral sketch is foreseen as an external link and that link with less asymmetry is foreseen as an internal link.
    [00020] Other details, advantages and characteristics of the invention result from the subsequent part of the description, in which an example of execution is described in more detail on the basis of the attached drawings. The figures show:

    [00027] Fig. 1 shows in perspective a partial area of an energy-carrying chain according to the invention, generally designated with the number 1. The energy-carrying chain 1 consists of a plurality of chain links 2, 3 hingedly interconnected. chain links 2, 3 are joined together in the form of two sections of parallel links and detachably joined by upper and lower crossmembers 4a, 4b. Between the link sections 2, 3 and the crossmembers 4a, 4b, the energy-carrying chain 1 forms a hollow compartment which serves as a conducting channel, for example, for cables or hoses. By the set of individual components consisting of two reciprocally opposite parallel links 2, 3 and the belonging crossmembers 4a, 4b, link components will be formed in a stable manner, rigid to rotation and torsion, as the smallest unit of repeated chain. The power-carrying current 1 shown can be deformed in an arcuate direction to form a lower section, a deflection region and an upper section, for example to join two mobile machine components relative to each other with power lines and/ or data lines.
    [00028] As can be seen in Fig. 1, alternate in each link section, in the longitudinal direction of the chain 1, internal links 2 of differentiated conformation, with external links 3. In the two link sections, however, will be used the same inner links 2 and the same outer links 3. As can be seen in more detail from figures 2 and 3, each inner link 2 and each outer link 3, specifically, in relation to its central plane of height S1 which extends perpendicularly to with the longitudinal direction, that is, towards the neutral fiber of the current carrying energy 1, it is shaped with specular symmetry. Correspondingly, by turning 180° around the height axis, both the inner link 2 and the outer link 3m can be used in the left or right link section as shown in Fig. 1.
    [00029] As also shown in Fig. 1, the hinged connections between the inner and outer links, 2, 3, alternating, are formed by a hinged element 5. As shown in Fig. 1, the hinged elements 5 extend, preferably, essentially, over the entire width of the links 2, 3 and end at their inner and outer side faces.
    [00030] The articulated element 5 is a plate-shaped and preferably separate component that extends in the longitudinal direction of the energy-carrying current 1. The corresponding articulated element 5 is being shown in more detail in Fig. 4. Correspondingly, the links 2, 3, also the articulated element 5 is configured in specular symmetry with respect to the vertical central plane S1. It covers a central area 51 as well as opposite terminal areas 52. In the example of embodiment shown, the articulated element 5 interconnects three links 2, 3, here always two outer links 3 and an inner link 2 in an intermediate position. For fixation on the inner link 2, the articulated element 5 has in the central area 51 two thickened sections 53 of transverse projection. The thickened sections 53 serving for protection, that is, fixing the inner link 2 in the longitudinal direction of the chain 1, are approximately cylindrical. Furthermore, in its central area 51 the hinged element 5, as can be better seen in Fig. 4b, has a cutout 54. The cutout is open only towards one side and in the longitudinal direction it is limited by the thickened sections 53. The articulated element fits with the cutout 54 in positive union in the central area of the inner link 2. With this, an additional fixation is obtained in the longitudinal direction and at the same time based on a bar 55 that limits the cutout 54 on one side, it is A fixation of the transverse direction towards the longitudinal direction is obtained, preferably against displacement outwards. For interconnection with the two outer links 3, the opposite end areas 52 of the hinge element 5 are shaped approximately in a semi-cylindrical shape. In the end areas 52, snap-on means are provided, in particular snap-on hooks 56. The snap-on hooks 56 are formed by notches transversely to the longitudinal direction, approximately the same depth as the cutout 54, being made in the areas thickened ends 52. On the side of the end areas opposite the counter hooks of the snap hooks 56, lugs 57 are provided, formed integral with the hinge element 5. The lugs 57 serve for the slack-free fitting of the snap hooks 56, i.e. articulated element 5 on external links 3 and vice versa.
    [00031] According to Fig. 4, the articulated elements 5, more precisely its trunk, similar to a plate, are shaped with a material thickness clearly smaller in its extension than the volume of its width and length. Made of suitable plastic, the articulated elements 5 thus act like a hinge band, i.e. a flexible leaf spring. In this way, the articulated elements 5, after bending in an angular position, the articulated elements 5 exert elastic return forces on the adjacent links 2, 3, so that the chain 1 has a tendency to be repositioned to its exit position . The articulated element 5 could also be shaped in such a way that essentially no return force is generated or only very little. For this purpose, for example, in the central part, between an end area 52 and the central area 51, a kind of thin film hinge can be provided so that the articulated element serves only for longitudinal protection.
    [00032] Therefore, the articulated element 5 is made of one-piece, for the elastic deformation (in the plane of Fig. 4a) on one side and for the formation of quick-fit hooks 56 on the other side, made of suitable plastic. For this purpose, a material will preferably be selected, compared to links 2, 3, a more suitable plastic. The head-shaped end areas 52, together with the thickened sections 53 and the cutout 54 in the central area ensure a high strength of the connection between the articulated element and the links 2, 3 in the traction direction.
    [00033] Furthermore, as can be better seen from Fig. 4a, each articulated element 5 has damping extensions 58 arranged in specular symmetry. The damping extensions 58 are shaped like a leaf spring, that is, with a thickness clearly less than their width and length. The damping extensions 58 are integrally profiled in the articulated element 5, that is, they are produced together with it, so that they protrude in a winged shape at an angle in the range between 30° and 90° towards the longitudinal axis of the articulated element 5. The damping extensions 58 may have a different profile than the arcuate shape shown in Fig. 4a. They can, for example, be formed in a zigzag wavy shape or at their ends with thickenings. The width of the damper extensions 58 in the transverse direction to a longitudinal direction of the energy-carrying chain 1 is smaller than the width of the articulated element 5. The damper extensions 58 are symmetrical towards the central longitudinal axis S1 (see Fig. 2a) and also symmetrical to the central vertical plane S2 (see Fig. 2a). The damper extensions 58 are cantilevered and have between their free end and the base point on the body of the articulated element 5 in length (of curves) between 5% and 25% of the height of the link 2, 3 in the plane of the central height. The damping extensions 58 serve to project with their free end in the area between two abutment surfaces of conjugative action of adjacent internal and external links 2, 3 in order to dampen the abutment and, therefore, to reduce the formation of noise. The damping extensions 58, however, in comparison with the body of the articulated element 5 essentially exert no return force. The above-mentioned characteristics of the articulated element are basically independent of the conformation according to the invention of the link sections according to the following description and can also be advantageously employed in other chains.
    [00034] Figures 2a-2e show a first form of the changing link types of the chain 1 of Fig. 1, precisely an inner link 2. As inner link 2, in this case it is understood that link that also in the area of the superposition with the respective neighboring link it faces the conductive channel 3 which is formed by the sections of parallel chains and by the beams 4a, 4b. The inner link 2 has an essentially butterfly-shaped base plate 21, which in the direction of its vertical central plane S1 and projects perpendicularly to the longitudinal direction is of symmetrical specular shape. A central area 22 of the inner link 2, compared to the base plate 21, is shaped thicker, as can be better seen from the perspective view in Fig. 2e. This thickened central area 22 forms a pair of first abutment surfaces 23 of specular symmetry and a pair of second abutment surfaces 24 of specular symmetry. The first and second stop surfaces 23, 24 are in specular symmetry with respect to the central raised plane S1. The first stop surfaces 23 can furthermore be specularly shaped in the direction of the second stop surfaces 24 with respect to the longitudinal center plane S2. Preferably, the first and second stop surfaces 23, 24 are, however, slightly asymmetrical with respect to the central longitudinal plane S2. With a corresponding slight asymmetry, by a 180° rotation around the transverse axis (cut line between the central planes S1 and S2), another limitation of the angular section can be adjusted, especially a prestressing adjustment may also be verified. To differentiate the chosen setting, on the inner side of the inner link 2, a corresponding marking 25 is provided.
    [00035] To receive and fix the articulated element 5, in the inner link 2, cutouts 26 directed towards the front side are provided. The cutouts 26 in the center and in symmetrical specular direction are projected both in the vertical central plane S1 and also in the longitudinal central plane S2. The end area towards the center of each cutout 26 is shaped for a positive union fit of the thickened sections 53 of the hinge element 5. The front region of each cutout 26, in turn, opens with increasing distance from the end area, which enables the desired bending of the articulated element 5. A central longitudinal cutout 26A, on the inner side, which can be better seen in Fig. 2b, serves to receive the bar 55 of the articulated element. In the inwards open cutouts 26 and in the longitudinal cutouts 26A, the hinge element will therefore be inserted from the inner side of the inner link 2.
    [00036] At the front, the inner link 2 has a pair of first lugs 27 and a pair of second lugs 28 that protrude transversely outward. The protrusions 27, 28 are also molded integrally with the base plate 21. The arrangement of the first and second protrusions 27, 28 corresponds, in terms of symmetries, similarly to that of the first and second stop surfaces 23, 24. auxiliary stops 29 are provided in the form of fillets which limit the cut-outs 26 in the direction parallel to the plane S1.
    [00037] Figures 3a-3e show an outer link 3 as a type of complementary link to the chain in Fig. 1. The outer link 3j has an essentially flat base plate 31, as well as a thickened central area 32 in front of the plate. base 31. The base plate 31 determines the contour in side view, which differs sharply from the symmetrical contour of the base plate 21 of the inner link 2. The contour of the outer link 3 has approximately the shape of a symmetrical, equal-sided trapezoid with narrow sides, ie basic, upper and lower sides, essentially straight and parallel to the longitudinal direction, but with curved flanks.
    [00038] The outer link 3 according to Fig. 3a-3e for limiting the position with less angulation has a pair of opposite first stop surfaces 33. The free support of the chain 1, among other factors, is also ensured by the first stop surfaces 33. The stop surfaces 33 are formed by the front sides of the outer link 3 and with respect to the vertical central plane S1 are formed with specular symmetry. The outer link 3 has, in addition, a pair of second stop surfaces 34, which are also opposite, being shaped with specular symmetry with respect to the vertical central plane S1. The second stop surfaces 34 serve to limit the relative position of two adjacent links 2, 3 with the greatest possible angle. As can be better seen in Fig. 3a and Fig. 3c, the first stop surfaces 33 and the second stop surfaces 34, however, do not have specular symmetry with respect to the longitudinal center plane S2, but are clearly asymmetric in the respective direction. The second stop surfaces 34, compared to the first stop surfaces, are offset towards the center and are slightly rotated around the central axis (cut line between planes S1 and S2). According to the pivoting position of the outer link 3 around the transverse axis, either the first stop surfaces 33 of the outer link 3 abut either the first stop surfaces 23 of the inner link 2 or the second stop surfaces 24 of the inner link 2. A procedure respectively inverse is valid analogously for the second stop surface 34 of the outer link 3. In this way, by arranging the outer link 3 with the shorter narrow side at the bottom, as shown in Fig. 3, or rotated by 180° with the side narrower at the top, the deflection direction of the energy-carrying current 1 can be changed. Varied arrangements in the longitudinal direction are also possible so that chains with wavy, zigzag or similar curved shape can be adjusted according to the use. Corresponding procedure applies analogously to the adjustment of a prestressing by disposing the inner link 2 with the first and second stop surfaces 23, 24 only slightly asymmetrical. In this way, not only will the drawing of the dynamic curve of the energy-carrying current be regulated by a suitable rotated arrangement of the internal and external links 2, 3, but a fine adjustment is also made possible. An adjustment can also be made with respect to the inactive balance position of the energy-carrying current 1, i.e., according to use, in a straight, prestressed or flexible direction, being finely adjusted.
    [00039] Fig. 3a-3e also shows a pair of longitudinally reciprocally opposed cutouts 36 that receive in positive union the head-shaped end areas 52 of the articulated element 5, as shown in Fig. 1. The cutouts 36, relative to the two planes S1 and S2 they are shaped with specular symmetry. In the end area 36, facing towards the center, the cutouts 36 are suitable in longitudinal section to the longitudinal cut of the end areas 52 of the articulated element 5. For the combined action with the respective quick-fit hook 56, in the end area, in the direction on the outside, a snap-in edge is provided, i.e. a snap-in stage 36B, which is positioned behind snap-in hooks 56 of the end area 52 in penetration. By the snap-on stage 36B and snap-on hook 56, the hinged element 5 will be locked on the outer link 3 in transverse direction and vice versa. By the fact that the outer links 3 are locked onto the inner links 2 by means of a snap-on connection 56, 36B, in transverse direction, saving of crossmembers 4a, 4b is made possible. Effectively, it is unnecessary - as can be seen from Fig. 1 - crossmembers 4a, 4b in the external links 3, so that these are provided, with cost and weight savings, only in the internal links 3. Alternatively, the crossmembers can also be provided only in the external links.
    [00040] The cutouts 36 have, in addition, auxiliary stops 39 in the form of a step in longitudinal section, which correspondingly to the first and second stop surfaces 33, 34 are arranged asymmetrically. The auxiliary stops 39 cooperate with the front auxiliary stops 29 in the cutouts of the inner link 2. The fillet-shaped auxiliary stops 29 serve, however, in particular to limit a relative displacement of the joined links 2, 3 in height and parallel direction. to the plane S2, that is, perpendicularly to the longitudinal direction, in a stretched position of the chain 1. For this purpose, the auxiliary stops 29 cooperate with the upper and lower bounding faces of the cutouts 36, which form the auxiliary stops 29. In order to limit displacement in the perpendicular direction with a maximum angular position, additional auxiliary stops 39A are provided in the outer link in specularly symmetrical shape. The other auxiliary stops 39A, for this purpose, are arranged in such a way that the corresponding narrow sides of the inner link 2 can rest against them.
    [00041] In the overlapping area of the outer link 3 with which it is superimposed in the opposite position, next to the inner link 2, a pair of first cutouts 37 and a pair of second cutouts 38 are provided. 37, 38 are approximately open in a sectorial fashion between the first and second stop surfaces 33, 34 and the thickened central area 32, being open towards the inner side. The first cutouts 37, as well as the second cutouts 38, are provided in pairs in specular symmetry with respect to the plane of central height S1. In the cutouts 37, 38, with the section joined, the first lugs 27 penetrate, that is, the second lugs 28. The height of the free cross section of the cutouts 37, 38 decreases, in this case, preferably in the direction of the stop surfaces 33, 34 to the extension of the corresponding height of the protrusions 27, 28, with which the deflector curve of the chain 1 will be stabilized. By the cutouts 37, 38 and by the protrusions 27, 28, which fit there, the perpendicular displacement to the longitudinal direction of the chain, together with auxiliary stops 29, 39A.
    [00042] Fig. 3c shows other pairs of third and fourth stop surfaces 37A, 38A that limit in the direction of the central plane of height S1, the cutouts 37, 38. As can be seen especially from the comparison of the top view and the isometry of according to Fig. 3d, i.e. Fig. 3e with the dorsal view according to Fig. 3c, the third and fourth stop surfaces 37A, 38A are formed at the front by the thickened central area 32. The central area 32, for the reinforcement between the stop surfaces 37A, 38A, has a form of rib structure with several longitudinal ribs and a central perpendicular rib, as shown in Fig. 3c.
    [00043] The third stop surfaces 37A, relative to the first stop surfaces 33, are also offset in the direction of the raised central plane S1 in specular symmetry, but in the direction of the center of the outer link 3. Corresponding indications are valid for the fourth stop surfaces 38A, with respect to the second stop surfaces 34. In the same way, as with the first and second stop surfaces 33, 34, also the third and fourth stop surfaces 37A, 38A are asymmetrical in the direction of the longitudinal center plane S2. The third and fourth stop surfaces 37A, 38A cooperate with the third and fourth stop surfaces 27A, 28A on the front faces of the inner link 2 in the area of the protrusions 27, 28. The third and fourth stop surfaces 27A, 28A; 37A, 38A therefore also limit, according to orientation, relative to the transverse axis, a possible largest possible or smallest possible angular section between adjacent links 2, 3.
    [00044] In the terminal area of the third and fourth stop surface 37A, 38A towards the central longitudinal plane S2 spatial cutouts (not named in more detail) of reduced depth can be provided, which can preferably collect in its entirety the thickness of the damping extensions 58 of the articulated elements 5. In this way, a deficiency in the combined action of the curved stop surfaces 37A, 38A, 27A, 28A will be avoided without losing the desired additional damping.
    [00045] As can be seen from the comparison of Fig. 2a with Fig. 3c, the extensions 27, 28 of the inner link 2, form pairs of fifth and sixth stop surfaces 27B, 28B, which - to further increase the entire length external abutment - cooperate with corresponding fifth and sixth abutment surfaces 37B, 38B of the outer link 3. The fifth and sixth abutment surfaces 27B, 28B of the inner link 2 are facing in the direction of the central plane S1. The fifth and sixth stop surfaces 37B, 38B of the outer link 3 border the cutouts 37, 38 as opposed to the third and fourth stop surfaces 37A, 38A. The central areas 22, 32, the extensions 27, 28 and the cutouts 37, 38 are so shaped and arranged that, in the stop position of the second stop surfaces 34, of the outer link 3 on the second stop surfaces 24, of the inner link 2, also the respective fourth stop surfaces 28A, 38A as well as the respective fifth stop surfaces 27B, 37B abut. Similarly, the conformation is such that in the stop position of the stop surfaces 33 of the outer link 3, on the first stop surfaces 23 on the inner link 2, also the respective third stop surfaces 27A, 37A, as well as the respective sixth stop surfaces 28B, 38B abut each other. All in all, this will ensure high stability in the respective stop.
    [00046] As can also be seen in figures 2a-2e and in Fig. 3a-3e, the first and second stop surfaces 23, 24 of the inner link and the corresponding first and second stop surfaces 33, 34 of the outer link of conjugate action , are formed curved. In order to make it possible to turn the outer link 3 around 180° without impairing the stability in the stop, the curvature of the stop surfaces 23, 24, 33, 34, in this case, is preferably identical. Preferably, identical curvatures will be provided that do not have a circular cylindrical shape, but allow a successive juxtaposition of the curved stop surfaces 23, 24, 33, 34. Conveniently, for example, the curvature can be in accordance with a suitable rolling curve, or ie, a cycloid. Correspondingly analogously, as it can also be of identical curvature, but with a more strongly expressed curvature, the third and fourth stop surfaces 37A, 38A of the outer link 3 and the third and fourth stop surfaces 27A, 28A of the inner link 2. By curved stops, on the one hand, a more slack-free and more stable configuration in the abutment can be achieved. Especially, the formation of noise will also be reduced due to the fact that a space stop in the effective direction is avoided. Furthermore, a kind of centering effect can be achieved in the main planes of the links 2, 3. The fifth and sixth stop surfaces 27B, 28B, 37A, 37B can be straight or flat, as also in Fig. 2a, i.e. Fig. 3c or also analogous, the aforementioned abutting faces 23, 24, 33, 34, i.e. 27A, 28A, 37A, 38A with a suitable curvature.
    [00047] The characteristics described below of a swivel tip as a separate connecting element for the crossmembers 4a, 4b basically do not depend on the conformation of the link sections according to the invention, which can also be advantageously employed in other chains.
    [00048] Figures 5a-5b show a swivel rod 60 as a separate component that serves for unilaterally fastening a crossmember 4a, 4b on the desired link 2, 3.
    [00049] The swivel rod 60, in the inward-facing end region, has a conventional shaped connector with snap-in lugs 62. These units protrude in the longitudinal direction (relative to chain 1), that is, transversely to the axis center of a coupled crossmember 4a, 4b and are arranged symmetrically as seen in Fig. 5b. The connector for the sleepers 4a, 4b is of known construction, that is, according to patent DE 53 31 066 of the supplicant and is therefore suitable for fitting the sleepers 4a, 4b of conventional shape.
    [00050] In the outwardly facing area, in turn, the swivel rod 60 has a hinge-like claw 64 that extends longitudinally, that is, in parallel to the protruding part of the engaging protrusions 62. The claw 64 it is used for fastening in a snap-on, but not swivelable, link. For snap-in connection, grip 64 has a snap-in shoulder or snap hooks 66 facing inward and axially extending.
    [00051] A mounting pin, i.e. a retaining rod 70 for snap connection with the claw 64 of the swivel rod 60 and the crossmember 4a, 4b with it joined, is provided in a cutout in the upper and lower narrow side of the link internal 2 as, for example, is shown in Fig. 2a-2e. Two retaining rods 70 are arranged symmetrically to the central longitudinal plane S2 with which upper and lower swiveling crossmembers can be fixed by means of corresponding swivel ends according to Fig. 5, as shown in Fig. 1. Alternatively, or in addition , corresponding retaining rods 70 could also be arranged on the outer links. The retaining rods 70 are provided in central cutouts in the central area 22 and extend in the longitudinal direction. As can be seen, moreover, especially in Fig. 2d, the retaining rods 70 are provided between the inner side and the outer side of the inner link, preferably in the centre. Correspondingly, conventionally shaped snap-in lugs from the links 2, 3 do not protrude into the interior, so that with the swivel tips released, the channel in the chain 1 offers easy access with no hooking of lines in the introduction and in the exit.
    [00052] Preferably, the retaining rods 70 have engagement means shown in more detail in figures 6a-c, which cooperate with the swivel tip for engagement in the retracted position (see Fig. 6a) and in a closed position (see Fig. 6b) . As can be better seen in Fig. 6a-6c, the retaining rods 70 in cross section have a certain arc with a step, that is, a cutout facing towards the center of the link. The latter forms 72 axial projection edges. The two engaging hooks 66 of the swivel rod 60 are positioned behind these edges 72 in the closed position according to Fig. 6c. As can best be seen from Fig. 6b, each retainer rod 70 also has an additional axial engagement notch 74 facing upwards, downwards, into which the internal engagement hook 66 penetrates to secure the crossmember 4a, 4b in position. open, i.e. retracted according to Fig. 6a. In addition, Fig. 5a also shows the additional stop 68 on the swivel rod 60. In the closed position, but clearly visible in Fig. 6c, the additional stop 68 is in positive engagement with a corresponding counter stop in the region of the upper edge. or lower facing inwardly of the central area 22 of the link 2. The cutouts in the link 2 that release the retainer rods 70 are correspondingly sized such that the swivel forward rod 60 is swivelable about the retainer rod 70. The center area 22 , at its upper and lower edge, as shown in Fig. 6b, is shaped uphill as a ramp for the inner and ascending, i.e. descending, side, so that also a corner of the swivel rod 60 is thus additionally retained in the retracted position. .
    [00053] The swivel rod 60 described above serves, therefore, as an adapter for rotatable fastening of conventional crossmembers 4a, 4b, shaped non-rotatable, on the chain links 2, 3. Also other links 2, 3, different than those described above , can receive retaining rods 70 compatible with swivel rods 60.
    [00054] In practice, in addition to the vertical specular symmetry of the components, the curvature proposed here of the stop surfaces 23, 33, 24, 33 of conjugated action has proven to be especially advantageous, as can be recognized by way of example in figures 2A, 3A, or that is, from Figures 2B and 3B. The successive juxtaposition that can be achieved in this way from the inside, that is, from the side of the articulated elements 5, to the outside, makes possible, due to a reduced elastic deformation of the links 2, 3 depending on the specific material, enables a specific juxtaposition of the links 2 , 3 and therefore a compensation for tolerances resulting from production. The juxtaposition of the curved stop surfaces 23, 33, 24, 34 is progressively continued until a stop is reached in the largest possible area in the stop. The proper curvilinear shape of the desired continuous curvature, that is, sharply monotonous, can be empirically determined through tests. The curved shape should be chosen especially as a function of the material selected from the different links 2, 3 and especially the articulated element 5 and this depends, among other factors, on the elasticity and joint kinematics.
