    Description
    The present invention relates to a connecting configuration for connecting a flexible cord profile to an attachment component that is rigid by comparison with the cord profile .
    A connecting configuration of this kind is required, for example, on a cord-type lock such as the one known from WO 2016/173716 A2. This known cord-type lock for the most part uses a non-metallic textile as a cord profile, arranged at each of whose longitudinal ends is an attachment component into which a locking mechanism of the known cord-type lock is received.
    While the cord profiles known from WO 2016/173716 A2 offer outstanding resistance to external break-in attacks, and withstand detachment attempts using various detachment and cutting tools for a long period of time, the unavoidable connection of the predominantly textile cord profile to the metallic attachment component is a possible further point of attack for break-in attempts. In principle, the possibility exists here of destroying the integrity of the cord-type lock without needing to cut through the cord profile for that purpose.
    The object of the present invention is therefore to describe a connecting configuration that ensures a secure connection of the flexible cord profile to the rigid attachment component.
    According to a general aspect of the present invention, this object is achieved in that at least one radially internal segment of a longitudinal end, facing toward the attachment component, of the cord profile penetrates as a penetration segment of the cord profile, in a pene tration direction, into a recess of a receiving segment, radially externally surrounding the penetration segment, of the attachment component, the penetration segment being secured by positive engagement on the attachment component, by the intermediary of a positive engagement arrangement, against being pulled out of the receiving segment oppositely to the penetration direction.
    The penetration segment can extend over the entire cross section of the cord profile or only over a radially internal part of the cross section. Advantageously, the cord profile is assembled from several coaxially arranged cord profile portions that can perform different tasks in the cord profile and for that purpose can be manufactured from different materials. For example, one cord profile portion can provide particularly high tensile strength for the cord profile, and a further cord profile portion, or several further cord profile portions, can serve as protection against being severed. The cord profile portion (s) that protect(s) against cutting is/are advantageously arranged radially as far outward as possible so as to be able to protect the greatest possible number of cord profile portions located radially farther inward. It is therefore sufficient for the penetration segment to be constituted only by a sub-group of all the cord profile portions that are present.
    Because the receiving segment radially externally surrounds the penetration segment, the penetration segment is protected by the robust receiving segment from external access. The receiving segment, like the attachment component as a whole, can be made at least predominantly of metal, in particular of high-strength steel, or also of ceramic .
    The result of securing the penetration segment in the receiving segment by means of the positive engagement arrangement is that the connecting configuration survives until at least one of the subassemblies involved - penetration segment, receiving segment, or positive engagement arrangement - is destroyed. With suitable material selection, aging of the materials involved in these subassemblies plays no part, so that destruction of the subassemblies involved represents the only possibility for overcoming the connection between the flexible cord profile and rigid attachment component in order to break open the cord-type lock without utilizing the confidential locking means intended to be used to open it.
    The positive engagement arrangement can comprise an encapsulation component that contacts the penetration segment in a first contact region and that, in a second contact region, contacts an inner wall, facing toward the penetration segment, of the receiving segment. For example, flowable encapsulation compound can be poured into gaps and cavities between the penetration segment and the inner wall of the receiving segment. If the cord profile is, as preferred, constituted predominantly or completely from textiles, the encapsulating compound in the flowable state can penetrate into textile meshes and thereby not only create an adhesive bond to textile surfaces, but also incorporate the textile in positively engaging fashion into the encapsulation component that is then made of hardened material.
    With the flowable encapsulation compound it is also easy to achieve undercut configurations engaging behind the receiving segment. The flowable encapsulation compound can thus flow past a radial projection protruding radially inward from the inner wall of the receiving segment and thereby, after curing, provide positively engaging pullout retention to prevent pulling out oppositely to the penetration direction.
    In order to furnish a positively engaging connection that is usable as broadly as possible, for example by the encapsulation component but, additionally or alternatively, also by other components to be explained below, it is therefore advantageous if the receiving segment comprises a constriction region and an undercut region located be hind the constriction region in the penetration direction, the undercut region having, orthogonally to the penetration direction, a greater unobstructed width than the constriction region. In this case the possibility always exists of arranging, in the undercut region of the receiving segment, one or more pullout prevention components that, because of their dimensional relationships relative to the unobstructed width of the constriction region, cannot be pulled out of the receiving segment through the constriction region oppositely to the penetration direction.
    It is therefore also advantageous, for creation of the positively engaged connection, that the positive engagement arrangement comprises at least one pullout prevention component, fixedly coupled to the penetration segment, which comprises at least one blocking segment that, arranged in the undercut region, has an outside dimension that is larger than the unobstructed width, to be measured in the same direction, of the constriction region, so that the blocking segment prevents a pulling-out movement oppositely to the penetration direction. This expressly includes the use of a plurality of pullout prevention components, each one of which can be configured in accordance with what is indicated in the description above.
    For attachment components that are constituted by joining several individual parts, at least one rigid pullout prevention component can certainly be used. Consideration can nevertheless also be given to placing at least one pullout prevention component through the constriction region of a one-piece attachment component in the undercut region. It can be advantageous for this purpose to embody the pullout prevention component as an expansion component, so that it can be passed through the constriction region in the penetration direction and, after passing through the constriction region, expands in the undercut region due to a preload. The preload can be furnished by a separate preload component. Preferably, however, the preload is based on a material elasticity of the expansion component itself.
    In design terms, according to a preferred embodiment of the present invention the pullout prevention component embodied as an expansion component can comprise a connecting segment connected to the penetration segment by positive engagement and/or by intermaterial connection. This connecting segment ensures a force transfer between the penetration segment and the pullout prevention component in and oppositely to the penetration direction, so that aside from any possible deformation, the penetration segment is immovable relative to the pullout prevention component in and oppositely to the penetration direction. The positively engaged connection can be achieved, for example, by the fact that teeth or barbs of the connecting segment, projecting toward the penetration segment, enter into the penetration segment, and/or by the fact that a projection, extending toward the penetration segment, of the connecting segment passes through a loop formed on the penetration segment or through textile meshes of the penetration segment. Additionally or alternatively, the connecting segment can be connected intermaterially to the penetration segment, an adhesive bond principally being conceivable here as an intermaterial connection. A projection of this kind can span the connecting segment diagonally, and can be connected at each of its two oppositely located longitudinal ends to the connecting segment.
    The pullout prevention component embodied as an expansion component furthermore comprises an expansion region that is movable at least locally toward the penetration segment against a returning preload force. The expansion region, which is preferably contiguous in one piece with the connecting segment, can comprise, for example, at least one radially movable expansion leg that that can be embodied, for example, as a spring leg that protrudes on one side from the connecting segment and is preloaded ra6 dially outward due to its material elasticity but is deflectable radially inward toward the penetration segment.
    Alternatively or additionally, the expansion region can be embodied in the manner of an expansion sleeve, and can surround the penetration segment in a circumferential direction without completely enclosing it. Those ends of the expansion sleeve-like expansion region which face toward one another in a circumferential direction are then preloaded away from one another in a circumferential direction due to their material elasticity, but can be moved toward one another against that preload. Here as well, a movement of parts of the expansion region toward and away from the penetration segment occurs.
    For easier passage of the expansion region through the constriction region in the penetration direction, it can preferably be embodied conically, or in general in a manner widening oppositely to the penetration direction.
    What has been stated regarding the connection of the connecting region to the penetration segment applies regardless of whether or not the pullout prevention component is embodied as an expansion component. The pullout prevention component can penetrate radially into the penetration segment, or can pass radially through the penetration segment, in order to produce a positively engaged connection between the pullout prevention component and the penetration segment. The pullout prevention component can be embodied as a projection, preferably embodied in one piece with the attachment component, that projects from the attachment component toward the penetration segment and passes partly or completely through it. In addition, the pullout prevention component can always be adhesively bonded to the penetration segment. Additionally or alternatively, the pullout prevention component can surround the penetration segment radially externally in a circumferential direction. The pullout prevention component can completely surround the penetration segment in a circumferential direction, although that need not obligatorily be the case.
    Additionally or alternatively, the positive engagement arrangement can comprise a loop embodied in one piece with the flexible cord profile. Such a loop can be produced in very simple fashion in the context of a cord profile embodied as a textile or cable. It is sufficient to produce the loop from one of the cord profile portions that form the penetration segment. A loop constituted in this fashion can then be passed through a segment of the attachment element .
    The constriction region can comprise at least one radial projection that projects from an inner wall of the receiving segment toward the penetration segment. The radial projection preferably proceeds in a circumferential direction around the receiving segment, so that the circumferential orientation of the attachment component relative to the penetration segment is immaterial. The radial projection can be constituted by a separate component, for example by a snap ring that is inserted into a groove in that inner wall of the attachment component which faces toward the penetration segment. That groove is preferably located at a distance of more than 10 mm, preferably more than 20 mm, from the longitudinal end of the attachment component through which the penetration segment penetrates into it, in order to make the snap ring inserted into the groove inaccessible to a tool or in fact not apparent to the naked eye on the completely assembled connecting configurat ion .
    The radial projection can also, however, be embodied in one piece with the attachment component or with an unfinished component thereof from which the attachment component is constituted.
    Although the attachment component can in principle be manufactured by casting technology as a one-piece monolithic component, in the interest of easy assembly of the connecting configuration it is preferred that the attach8 ment component encompass several sub-components. In the interest of optimum protection of the penetration segment from undesired external access, those sub-components are joined nondetachably to produce the attachment component .
    For example, the attachment component can encompass a tubular component that at its one longitudinal end comprises a receiving segment, and at its other end is closed off by an end component. To avoid seams, the tubular component is preferably embodied in one piece. The end component can be welded or soldered to the tubular component, or pressed into it. The receiving segment constituted in the tubular component is thus accessible only through a single opening through which the cord profile extends into the receiving segment.
    As an alternative to the physical conformation recited in the preceding paragraph, the attachment component can comprise at least two tubular sub-components that are arranged one behind another in the penetration direction. The tubular sub-components can be joined to one another, by welding, soldering, heat shrinking, and the like, to produce a larger tubular sub-component or the attachment component. In this case one tubular sub-component can constitute the constriction region and at least one further tubular sub-component can constitute at least a segment of the undercut region. In order to minimize the number of components needed in order to constitute the attachment component, the at least one further tubular sub-component is closed at its longitudinal end facing away from the first tubular sub-component.
    According to a particularly preferred embodiment of the present invention, the attachment component encompasses at least two sub-components whose parting surface or joining surface extends at least locally in the penetration direction. Preferably their parting surface or joining surface extends entirely in the penetration direction, in particular in the form of a parting plane or joining plane. Constituting the attachment component from sub-components configured in this manner allows them to be produced as forged parts, which in addition to material selection also results in high-strength, tamper-proof components as a result of the work hardening that occurs upon forging. Preferably the attachment component is constituted from exactly two such sub-components. In the preferred case just recited, the sub-components are identical parts that are embodied mirror-symmetrically with reference to their parting plane or joining plane, and/or are embodied at least locally rotationally symmetrically with reference to an axis of rotational symmetry located in their parting plane or joining plane. In this case one forging die is sufficient for manufacturing both sub-components of the attachment component.
    The sub-components are preferably connected to one another intermaterially and/or by positive engagement. Welding is preferred as an intermaterial connection, but brazing is also not to be excluded. Additionally or alternatively, a positively engaged connection can be constituted or at least assisted by a shrinkage connection and/or press connection. For example, the sub-components can be connected by way of shrink rings that externally surround them. Preferably the shrink rings are recessed into grooves on the outer side of the sub-components in order to make them more difficult to access for an attack with tools. For this purpose, preferably each of two shrink rings is slid onto the attachment component from a different longitudinal end thereof, and inserted into a groove, embodied specifically for the respective shrink ring, in the attachment component. In order to make the shrink rings as inaccessible as possible for an attack with tools, with the attachment component in the completely assembled state the groove flanks that face oppositely to the respective slide-on direction of the shrink ring are flush with the respective radially outer enveloping surface of the shrink ring, or in fact protrude radially beyond it.
    In addition or as an alternative to the shrink rings onto recited above which are radially externally shrunk the attachment component, at least one projection projects from a sub-component of the attachment component can be anchored, using a pressing and/or shrinkage technique, in a corresponding recess on component of the attachment component bined with the further sub-component.
    that further that sub comFor this, the component having the projection can be shrunk by cooling and/or the having the recess heating. The is that they pin can be projections joining surfaces at a distance from an or component edge, so that after components are combined, the pin and by the resulting component itself and accessible .

    profile having one or two attachment components on one or both longitudinal ends can be modified, by way of a shackle lock or a further cord-type lock, to yield a cord-type lock, such that the shackle lock or the further cord-type theft-proof with no particuis thereby possifrom becoming too lock can be configured to be lar provision of installation ble to prevent the attachment space. It components bulky because of the closure mechanism to be received m them, and thereby negating the weight advantage achieved thanks to the use of a woven textile cord profile. According to a further preferred embodiment of the present invention, provision is therefore made that at least two sub-components each comprise a receiving configuration portion that, after connection of the sub-components as intended, form a receiving configuration for receiving an eyelet. The term eyelet refers in this context to any type of continuously peripheral conformation having a central passage. The eyelet in particular does not need to be annular in shape.
    The provision of a receiving configuration instead of rigid attachment of an eyelet has the advantage that eyelets of different sizes can be arranged on one and the same attachment component, the material thickness of the eyelet torus preferably being the same regardless of the size of the eyelet. This makes it possible in the context of production of the attachment component to prepare the resulting cord profile, or the cord-type lock resulting from the cord profile and attachment component, at a very late point in time in the production process. The receiving configuration is therefore embodied to receive eyelets of different sizes. This presents absolutely no difficulty with rectangular eyelets, since in this case, regardless of the size of the eyelet, what must be received in the receiving configuration is always a cylindrical segment of the eyelet that can have the same diameter or, when square profiles are used as an eyelet, the same diagonal dimension .
    When prefabricated annular eyelets, which are particularly easily available commercially, are used, the difficulty with regard to receiving eyelets of different sizes is that they have different curvatures depending on their size. Provision can therefore be made that the receiving configuration comprises a passthrough opening whose one delimiting wall is more strongly curved than its diagonally oppositely located delimiting wall. In the completely assembled state, the more strongly curved delimiting wall is located opposite a radially inwardly facing segment of the eyelet torus, and with the attachment component in the completely assembled state the less strongly curved, or even not curved, delimiting wall located oppositely to it is correspondingly located opposite a radially outwardly facing segment of the eyelet torus. Radially inward and radially outward refer here to the center point of the eyelet opening surrounded by the eyelet torus.
    As already described, provision is preferably made that the cord profile encompasses a textile cord so as to configure it with the least possible weight . In order to increase the break-in resistance of the cord profile used in a cord-type lock, it can preferably encompass a plurality of textile cords, at least one textile cord of the cord profile encompassing aramid fibers in the interest of increased strength. The cord profile can furthermore comprise nonmetallic fibers in the form of a laid cable, preferably as the core of the cord profile, around which at least one, preferably several, textile cords are coaxially arranged. It should not be excluded that one or more of the textile cords can encompass one or more metallic fibers, either in order thereby to achieve a protective effect with respect to a specific type of tool, or in order to use the at least one metallic fiber as a signal transfer lead. Preferably the cord profile is embodied as described in WO 2016/173716 A2.
    Because the connecting configuration discussed above possesses particular value in the manufacture of highly secure cord-type locks with little weight, the present invention also relates to a cord-type lock having a connecting configuration as described and refined above. The cord profile of the connecting configuration forms the cord of the cord-type lock. At least one attachment component can receive either a closure mechanism or a positive engagement configuration interacting with a cord-type lock or shackle lock. The cord-type lock or shackle lock used in order to close the cord-type lock according to the present invention can have a considerably shorter cord length or shackle length compared with the cord-type lock according to the present invention, so that its weight does not appreciably increase the total weight of the cord-type lock according to the present invention.
    The present invention furthermore relates to a use of a connecting configuration according to one of the preceding claims in a cord-type lock for securing objects.
    A connecting configuration in accordance with the description above is preferably configured at each longitudinal end of the cord profile.
    The present invention will be described below with reference to the attached drawings, in which:
    FIG. 1 is a roughly schematic plan view of an embodiment according to the present invention of a connecting configuration; and
    FIG. 2 is a section view, along section plane Illi of FIG. 1, of the plan view of FIG. 1.
    In FIGS. 1 and 2, an embodiment according to the present invention of a connecting configuration of the present Application is labeled in general as 10. Connecting configuration 10 encompasses a cord profile 12 and an attachment component 14 arranged thereon at a longitudinal end.
    As is evident from FIG. 2, cord profile 12 encompasses at least three coaxial cord profile portions 16, 18, and 20, of which cord profile portion 20 is the radi ally innermost and thus forms a core of cord profile 12. In the exemplifying embodiment depicted, at least cord profile portion 20 is constituted from an aramid fiber textile and exhibits extremely high tensile strength. Cord profile portions 16 and 18 located radially farther outward are also constituted as a textile made of plastic fibers and/or metal fibers and/or natural fibers. Because they radially externally surround the radially innermost cord profile portion 20, they are embodied as textile tubes .
    Attachment component 14 comprises a receiving segment 22, open toward cord profile 12, into which a penetration segment 24, encompassing a longitudinal end of cord profile 12, penetrates in penetration direction 26 along penetration axis E.
    Penetration segment 24 is secured in receiving segment 22, by positive engagement, against being pulled out oppositely to penetration direction 26. Attachment component 14 has for that purpose, in receiving segment 22, a constriction region 28 having a narrower opening cross section, and an undercut region 30, located behind constriction region 28 in penetration direction 26, that has a larger opening cross section than constriction region 28 adjacent to it. The opening cross sections are each to be construed as being orthogonal to penetration axis E.
    Attachment component 14 thus comprises, in receiving segment 22, a recess 32 in which penetration segment 24 of the flexible cord profile 12 is received.
    Two positive engagement bolts 34 and 36, constituting part of a positive engagement arrangement 38, are fixedly arranged on the flexible cord profile 12, in particular (in the exemplifying embodiment depicted) on cord profile portion 20. Positive engagement bolts 34 can be passed through cord profile portion 20, for example through spread-out weave meshes of cord profile 20, orthogonally to penetration axis E, while maintaining the material cohesion of the fibers constituting the textile of cord profile portion 20. Positive engagement bolts 34 can additionally be connected intermaterially to cord profile portion 20 by means of an adhesive. Portions 34a and 36a, projecting radially beyond the cord profile portion carrying them, of positive engagement bolts 34 and 36 form blocking segments that effectively prevent cord profile 12 from being pulled out of attachment component 14.
    In order to enhance the resistance of cord profile 12 to being pulled out of attachment component 14 in different spatial directions, positive engagement bolts 34 and 36, preferably made of high-strength steel and/or ceramic, are each passed through cord profile portion 20 orthogonally to penetration axis E; the longitudinal bolt axes of positive engagement bolts 34 and 36 are preferably oriented orthogonally to one another.
    Alternatively, instead of positive engagement bolt 34 located farther away from the longitudinal end of cord profile 12 it is also possible to provide a ring, radially externally surrounding cord profile 12, which is held by positive engagement on cord profile portion 20 by way of positive engagement bolt 36 located closer to the longitudinal end of cord profile 12. Numerous other positive engagement configurations, as described or indicated above in the descriptive introduction, can be used in addition or alternatively to positive engagement bolts 34 and 36 shown by way of example.
    With the connecting configuration in the completely assembled state, the two positive engagement bolts 34 and 36 are located in undercut region 30, which, along with cord profile portion 20, they cannot leave oppositely to penetration direction 26 because of the dimensional relationships of the lengths of bolts 34 and 36 with respect to the opening cross section of constriction region 28, since constriction region 28 constitutes an insuperable physical barrier to positive engagement bolts 34 and 36 that are provided in the above-described orientation on cord profile portion 20.
    The gap remaining between cord profile 12 and recess 32 of attachment component 14 after the placement of penetration segment 24 and of positive engagement arrangement 38 in receiving segment 22 of the attachment component can be filled up with encapsulation compound 40 which, for example constituting a two-component encapsulation compound, cures unassistedly in a predetermined time span as a re suit of a chemical reaction. An encapsulation component 42, which radially inwardly at least contacts cord profile portion 20 or preferably in fact penetrates into its weave meshes, and which radially outwardly contacts inner wall 44 of receiving segment 22, can thus additionally be arranged in receiving segment 22.
    Encapsulation component 42 is also a part of positive engagement configuration 38.
    Attachment component 14 is preferably constructed as a forged component made of high-strength steel having a hardness of more than 60 HRC, preferably more than 65 HRC, from two sub-components, of which only sub-component 46 is shown in plan view in FIG. 1, and only sub-component 46 is shown in section in FIG. 2. The sub-components of the attachment component are identical parts that can be manufactured in one and the same forging die, so that a depiction of the other sub-component that, together with subcomponent 46, constitutes attachment component 14, is superfluous .
    In the exemplifying embodiment depicted, the subcomponents of attachment component 14 are connected by way of two shrink rings 48 and 50 arranged along penetration axis E with a spacing from one another.
    Shrink rings 48 and 50 are respectively slid onto attachment component 14, in opposite directions, from those longitudinal ends of attachment component 14 which are located closest to them. Their arrangement is mirrorsymmetrical with reference to a mirror symmetry plane passing through attachment component 14 orthogonally to penetration axis E halfway between shrink rings 48 and 50, so that a description of the arrangement of shrink ring 50 on attachment component 14 also applies to shrink ring 48, given the symmetry condition indicated.
    Shrink ring 50 is set into a groove 52, surrounding attachment component 14 orthogonally to penetration axis E, in attachment component 14, groove flank 54 of which facing oppositely to the apparent slide-on direction of shrink ring 50 (oppositely to penetration direction 26) is at least flush with the radially outer enveloping surface of shrink ring 50, or in fact projects radially beyond it. It thereby becomes more difficult to engage a tool onto shrink ring 50 in order to remove it.
    Additionally or alternatively, the two sub-components of attachment component 14 can be connected to one another by way of a projection/recess shrink connection (press fit); this is indicated in FIG. 1, using dashed lines, by way of a first projection/recess combination of projection 56 and recess 58, and by a second projection/recess combination of projection 60 and recess 62. Projections 56 and 60, and recesses 58 and 62 that receive them, extend orthogonally to the drawing plane of FIG. 1 and parallel to the drawing plane of FIG. 2; projections 56 and 60, and recesses 58 and 62, proceed from the exposed joining surface 64, embodied for contacting the respective other subcomponent of attachment component 14, of the respective sub-component. As a constituent of an identical part set, each sub-component comprises a projection and a recess. Sub-component 46 depicted in FIG. 2 comprises, for example, projection 56 that is located behind the drawing plane of FIG. 2 (and is therefore not depicted) and recess 62 that is located in front of the drawing plane (and is therefore once again not depicted).
    Additionally or alternatively, after being fitted together to form attachment component 14 the two subcomponents of attachment component 14 can be welded to one another, for example by laser welding, along the parting seam or joining seam visible on the outer wall of attachment component 14, .
    Attachment component 14 comprises, in the region between its longitudinal end located remotely from cord profile 12 and undercut region 30, a receiving configuration 66 that is embodied to receive an eyelet. Receiving con figuration 66 is marked with dashed lines in the plan view of FIG. 2. It constitutes a curved passage 68 through attachment component 14; passage 68 tapers, proceeding from one edge region of attachment component 14 having an open5 ing of passage 68, toward the respective other edge region of attachment component 14 having the other opening of passage 68, and widens again after reaching a minimum opening cross section. Passage 68 is preferably curved in only one spatial direction, specifically (in the exempli10 fying embodiment depicted) around an axis of curvature orthogonal to the drawing plane of FIG. 1.
    In order to create the capability of receiving, in receiving configuration 66, eyelets that have different eye sizes -- but that, for security reasons, preferably 15 have the same material thickness in each case -- receiving configuration 66 has a stronger curvature in the region located closer to the axis of curvature of the passage than in that region of passage 68 which is located farther from the axis of curvature.
