Description

[0001] The subject of the invention is a U-clamp for fastening a long item, for example an electrical cable, to a support structure having an undercut fastener channel, for example a rung of a cable ladder, with a U-clamp part, through the legs of which and the bridge part connecting the legs a long item receptacle is enclosed and the legs of which carry at their end at least one anchoring element which can be inserted into the undercut of the fastener channel of the support structure with an abutment section aligned transversely to the longitudinal extent of the fastener channel, with a pressure plate which is adjustable relative to the legs in the direction of their longitudinal extent and acts on the support structure to fasten a long item to the support structure and with a tensioning device for tensioning a long item which passes through the long item receptacle to the support structure.

[0002] Such U-clamps are used to fasten long items, such as electrical cables or the like, to a supporting structure, for example the rung of a cable ladder. Such a U-clamp comprises a typically U-shaped bracket part. The bracket part comprises two legs arranged at a distance from one another and a bridge part connecting the two legs. A long item receptacle is enclosed by the bracket part, through which a long item to be fastened is passed. At the ends facing away from the bridge part, the legs each carry an anchoring element. The anchoring elements are designed to be inserted into an undercut in the supporting structure in order to provide a tensioning abutment by engaging in the undercut. Each anchoring element has at least one abutment section for engaging in an undercut in the fastener channel, which abutment section extends transversely to the longitudinal extent of the fastener channel of the supporting structure oris aligned in the longitudinal direction of the long material holder. U-bolt clamps of this type either have an abutment section on the anchoring elements of their legs, each pointing in the same direction, or each leg has two abutment sections pointing in opposite directions. A U-bolt clamp with abutment sections oriented on one side serves to fasten the clamp on one side and thus only to one edge area of ​​an opening of a fastening channel of a supporting structure. In the other case, the anchoring element with its abutment sections is designed like a hammer head and engages behind both sections that delimit an installation opening of a fastening channel of a supporting structure.Due to the required design of the anchoring elements with their abutment sections, such U-clamps cannot be inserted into the mounting opening of a supporting structure's fastener channel by merely translating. In order to insert the abutment sections into the undercut, these previously known U-clamps must be pivoted or screwed into the mounting opening of the fastener channel with their anchoring elements. U-clamps with anchoring elements that each have two abutment sections facing away from each other must therefore be of unequal length. Furthermore, with such a U-clamp, it is not possible to design the abutment section in a hook shape, as is the case with U-clamps with only one-sided abutment sections.Such a hook-shaped design of the abutment sections is preferred for many applications, since the mounting opening of such fastener channels is typically defined by short legs directed into the fastener channel. These legs laterally border the mounting opening, following its longitudinal extension. The hook of an abutment section designed in this way can then also engage the undercut provided by these beveled legs.

[0003] Such clamps are known from the applicant. They are sold, for example, under the designation BS-U1-M or BS-H1-M.

[0004] A disadvantage of such U-clamps is that, in order to be properly swiveled into a mounting opening in a fastening channel of a supporting structure, the legs of the U-clamp must have a corresponding height if the U-clamp is to be fastened to the supporting structure with a long item passed through its long item holder. Screwing in such a U-clamp with a long item already passed through its long item holder is only possible if there is sufficient free space adjacent to the intended mounting location. If such a supporting structure is already equipped with several long items, such a U-clamp can only be installed in any remaining free space without the long item to be fastened with this U-clamp. In this type of use, the long item can only be passed through the long item channel afterwards.

[0005] Based on the prior art described above, the object of the invention is to propose a clamp which can be easily connected to a supporting structure even in confined installation conditions and with a long item guided through its long item holder by inserting its anchoring elements with their abutment sections into the fastener channel, wherein an engagement in the undercuts of the fastener channel opposite one another with respect to the installation opening would be preferred.

[0006] This object is achieved according to the invention by a generic U-clamp mentioned at the outset, in which the U-shaped part is designed in several parts and comprises a first U-shaped element and a second U-shaped element, in which U-shaped elements the abutment sections of their anchoring elements are arranged pointing in opposite directions and in which the U-shaped elements are adjustable relative to one another in the direction in which a long item passes through the long item holder in order to reduce the effective width of the U-shaped clamp in this direction in the section of their anchoring elements.

[0007] The special feature of this U-bolt clamp is that its clamp section is designed in several parts. The clamp section comprises a first clamp element and a second clamp element. Each clamp element provides one leg of the clamp section with an anchoring element. The abutment sections of the anchoring elements of the two clamp elements point in opposite directions. This means that the abutment section of each clamp element engages behind a lateral border of the fastener channel of a supporting structure. When viewed together with both clamp elements, the clamp part engages with its abutment sections of the anchoring elements in the two undercuts of a fastener channel that are opposite each other with respect to the installation opening. The two clamp elements are adjustable against each other so that they can be inserted with their abutment sections into the undercuts of the fastener channel that are opposite each other with respect to the longitudinal extent of the installation opening.The adjustment direction of the two stirrup elements relative to each other is intended to be in the direction in which a long item passes through the long item holder and thus in the direction of the installation direction of a fastener channel. This allows the effective width of the stirrup clamp in the section of its anchoring elements and thus its span at its abutment sections to be reduced from a delivery position, which typically corresponds to the anchoring position, so that both anchoring elements can be guided through the installation opening of a fastener channel in this position of the stirrup part using a translational installation movement alone. Once the abutment sections of the two stirrup elements have been guided through the installation opening of a fastener channel, they are spread apart from each other so that the abutment sections engage in the respective undercut of the fastener channel.In a preferred embodiment, the adjustability of the bracket elements relative to one another against the restoring force of a spring element is provided, so that the above-described spreading process and thus the introduction of the abutment sections into the undercuts takes place automatically.

[0008] Such a U-clamp can be easily mounted on a supporting structure with or without long goods passed through its long goods receptacle, even in confined installation conditions. Therefore, such a U-clamp does not need to have any additional height to allow it to be pivoted into the mounting opening of a fastener channel with long goods passed through its long goods feedthrough. Another advantage is that such a U-clamp engages behind the mounting opening of a fastener channel on both sides. Unlike conventional U-clamps with hammerhead-shaped anchoring elements on their legs, the barb sections can also be designed in a hook-shaped manner, so that the anchoring elements can engage behind on both sides even in supporting structures where the mounting opening is limited by legs beveled towards the fastener channel.

[0009] The articulated engagement of the two bracket elements of the bracket part of this fastening clamp can be achieved in that the bracket elements carry first and second support sections which, when engaged with one another, provide the bridge part. These first and second support sections are designed such that each bracket element is supported by a first support section on a second support section of the other bracket element in the direction of the long goods holder. The first and second support sections of the bracket elements are arranged at a height offset from one another, wherein the height offset typically corresponds to the material thickness of a support section of such a bracket element. According to one embodiment, the support sections are extensions or components of an angled leg with the two support sections, angled out of the plane of the legs of the respective bracket element in the direction of the other bracket element.

[0010] For the positive engagement of the two bracket elements in the region of their support sections, one embodiment provides for a stop that is angled relative to at least one support section of each bracket element. This stop interacts with the adjacent support section of the other bracket element for the positive arrangement of the two bracket elements in the direction of the longitudinal extent of the long goods holder when the support sections are engaged. In a further development of such a stop design, it is provided for such a stop to be designed with regard to its planar extent so that it assumes an additional functionality. For example, such a stop can simultaneously provide part of a holder for a component of the clamping device, such as a clamping nut.In such a case, such a stop will preferably be designed with a somewhat larger flat extension in order to provide an effective contact surface for the key flat of a clamping nut. In another embodiment of a further use of such a stop, it is provided to be designed as a leg part, which, with regard to the orientation of its anchoring element with the abutment section located thereon, is designed in the same way as the actual leg of this stirrup element. Then, both stirrup elements each have two leg parts, which then form the legs of the stirrup part when the stirrup elements are engaged.

[0011] Each leg of the bracket section is then widened by two leg sections, with each leg section being part of a different bracket element. In this configuration, the bracket clamp then has anchoring elements in the area of ​​each leg, the abutment sections of which point in opposite directions. With such a configuration, each leg is locked on both sides to the fastener channel. The support sections can also carry angled functional surfaces, as described above, regardless of whether a stop is formed on them.

[0012] For example, a clamping screw and a clamping nut can be provided as the clamping device. The clamping screw then extends through the support sections of the bracket elements. In one embodiment, the first and second support sections of such a bracket element are separated or spaced apart from one another by a clamping device recess through which the clamping screw extends.

[0013] In a preferred embodiment, an adjusting plate acts on the upper side of the engaged support sections of the stirrup elements under prestress. This adjusting plate can be adjusted against the restoring force of the prestressing force. The adjusting plate holds the stirrup elements in a position relative to one another in which the abutment sections of their anchoring elements engage in the undercuts of a fastener channel, thus being spread apart from one another. This is typically the delivery position of such a stirrup clamp with regard to its stirrup elements. Adjusting the stirrup elements to reduce the span of their abutment sections then acts with the upper side of their support sections against the prestressing force, so that after the anchoring elements have been passed through the installation opening of a fastener channel, these or their abutment sections automatically spring into the respective undercut.The preload force can be provided, for example, by a helical compression spring mounted on the threaded shaft of a clamping screw. In such a design, a suitably dimensioned washer typically serves as the adjusting plate.

[0014] The pressure plate is used to apply clamping pressure to a long item passing through the long item holder, via which the clamping force is distributed over an area of ​​the surface of the long item. If a clamping screw is provided as part of the clamping device, according to one embodiment, this screw is connected to the pressure plate by its base, typically during a riveting process, in which the base of the clamping screw passes through a corresponding opening in the pressure plate and is expanded accordingly. Such a pressure plate can have two leg openings. These serve the purpose of ensuring that the leg of a bracket element passes through such a leg opening. These serve to guide the bracket elements, which are adjustable relative to one another.

[0015] As a result of the central or central application of the clamping force to a long item passing through the long item holder in relation to the width of an assembly opening of a supporting structure, the long item is fixed to the supporting structure or clamped against it equally at both sections delimiting the assembly opening.

[0016] A design in which the U-clamp is assigned an additional support member, which limits the long goods holder in the direction of the anchoring element. Such a support member typically extends across the width of the supporting structure, for example the rung of a cable ladder. The long goods then rests on the upper side of the support member. This is expediently U-shaped, as is the pressure plate, with the opening sides of the pressure plate and support member facing each other. Such a support member can, like the pressure plate, also have two leg openings, each of which is penetrated by the leg of a U-clamp element. A design in which the pressure plate does not act directly on the outer surface of a long goods item guided through the long goods holder, but rather with the interposition of a typically larger-sized tendon.In such a design, the leg can have perforations. The pressure plate itself can then be located entirely between the legs and does not require any perforations.

[0017] If desired, such a clamp can be designed as an earthing clamp. In this case, at least the pressure plate or, if the pressure plate acts on a tensioning member, the latter typically has several penetrating elements. The electrically conductive connection to the electrically conductive support structure is established via the clamp part. In such a design, for contact purposes, it is preferred if the clamp also has a support member, which is then also equipped with penetrating elements. During tensioning of the clamp, the penetrating elements are pushed through the sheath insulation of the electrical cable passing through the long goods holder in order to establish electrical contact with the outer earth conductor.

[0018] The invention is explained below using exemplary embodiments with reference to the attached figures. They show: Fig. 1: A perspective view of a clamp according to the invention attached to a rung as a supporting structure, Fig. 2: a perspective view of the clamp of the Fig. 1 in sole representation, Fig. 3: the clamp of the Fig. 2 with its components, shown in an exploded view, Fig. 4: a view of the long goods holder of the bracket part of the bracket clamp of the previous figures, Fig. 5: a side view of the clamp with the clamp elements of the clamp part adjusted relative to each other in the direction of the longitudinal extension of the long goods holder, Fig. 6: the clamp with a long item passed through its long item holder during the process of attaching it to the rung, Fig. 7: the representation of the clamp attached to a rung with a long item guided through its long item holder according to Fig. 1 in a side view, Fig. 8: a perspective view of another clamp according to the invention attached to a rung as a supporting structure, Fig. 9: a perspective view of the clamp of the Fig. 8 and Fig. 10: a perspective view of the clamp of the Fig. 9, shown in an exploded view.

[0019] A U-clamp 1 is used to fasten a long item, which in the illustrated embodiment is an electrical cable 2, to a supporting structure. In the illustrated embodiment, the supporting structure is realized by a rung 3 of a cable ladder (not otherwise shown in detail). The rung 3 has a fastener channel 4 following its longitudinal extent and a mounting opening 5 also following its longitudinal extent. The fastener channel 4 is undercut on both sides of the mounting opening 5. In the illustrated embodiment, the mounting opening 5 is delimited by two legs 6, 6.1 angled towards the fastener channel 4.

[0020] The clamp 1 has a clamp part 7 (see also Fig. 2 and Fig. 3). The bracket part 7 of the illustrated embodiment consists of two bracket elements 8, 9, which, when engaged with each other, form the bracket part 7. Enclosed by the bracket part 7 is a long goods holder 10, which, as in Fig. 1, through which the cable 2 mounted on the rung 3 passes. The clamp 1 further comprises a pressure plate 11, which acts against an upper section of the outer surface of the electrical cable 2 to fasten the clamp 1 with the cable 2 to the rung 3. As a tensioning device, the clamp 1 has a tensioning screw 12, which, with the interposition of a compression spring 13 and an adjusting plate 14, acts on the bridge part 15 forming the upper side of the clamp part 7. On the underside of the bridge part 15 there is a tensioning nut 16 (see Fig. 3). The pressure plate 11 is connected to the base end of the clamping screw 12. The base of the clamping screw 12 has a rivet extension 17 that passes through an opening 18 of the pressure plate 11 and is riveted to it, while retaining the rotational mobility of the clamping screw 12 relative to the pressure plate 11. The pressure plate 11 is held between the bracket elements 8, 9 in a rotationally decoupled manner with respect to the rotational movement of the clamping screw 12 due to its contour geometry.

[0021] Each bracket part 8, 9 has a leg 19, 20, each of which carries an anchoring element 21, 22 on its underside. The anchoring elements 21, 22 each have an abutment section 23, 24 that engages behind the fastener channel 4. The abutment sections 23, 24 are hook-shaped and point in opposite directions. Therefore, the bracket clamp 1, with its abutment sections 23, 24, engages behind the mounting opening 5 on both sides, as is conventionally known from hammerhead-shaped anchoring elements.

[0022] To provide the bridge part 15 connecting the legs 19, 20, each bracket element 8, 9 has two complementary support sections, a first support section 25, 26 and a second support section 25.1, 26.1. These are extensions angled from the plane of the legs 19, 20. The support sections 25, 26; 25.1, 26.1 are designed so that when the two bracket elements 8, 9 are engaged with one another via the support sections 25, 26; 25.1, 26.1, the bridge part 15 is formed. The first support sections 25, 25.1 are arranged at a height offset from the second support sections 26, 26.1 and, in the illustrated embodiment, are in a recessed position relative to the plane of the second support sections 26, 26.1. The height offset corresponds to the material thickness of the second support sections 26, 26.1 that are placed thereon. Between the first and second support sections 25, 26; 25.1, 26.1, each bracket element 8, 9 has a clamping device recess 27. The section of the bracket elements 8, 9 that is angled relative to the legs 8, 9 also has stops that are beveled relative to the plane of the bridge part 15, with each bracket element having two such stops 28, 28.1. The stops 28, 28.1, with their mutually facing flat sides, serve as a stop and at the same time as an adjustment surface when the bracket elements 8, 9 are adjusted relative to one another in the direction of the longitudinal extent of the long material holder 10. When the bracket elements 8, 9 are engaged with one another, the stops 28 and 28.1 are located in one plane. Furthermore, the stops 28, 28.1 serve to hold the two bracket elements 8, 9 positively against one another in their engaged position in the longitudinal direction of the long material holder 10. For this purpose, the stops 28, 28.1 interact with the narrow sides of the support sections 25, 26; 25.1, 26.1.

[0023] The engagement position of the two bracket elements 8, 9 for forming the bracket part 7 is in the direction of view towards the underside of the bridge part 15 in Fig. 4. The first support sections 25, 25.1 each carry at their ends a clamping nut contact extension 29, 29.1, which is bent toward the long material holder 10 and provides a receptacle for the clamping nut 16. The flat sides of the clamping nut contact extensions 29, 29.1 are spaced apart from one another so that the clamping nut 16 rests against them with two opposing wrench surfaces, at least being held between them in a torque-locking manner.

[0024] Due to the described engagement position of the two bracket elements 8, 9, these are, as in Fig. 5, are adjustable relative to each other in the direction of the longitudinal extension of the long goods holder 10. The compression spring 13 holds the bracket elements 8, 9 in their Fig. 2, in which the upper sides of the bracket elements 8, 9 are aligned. This adjustment of the bracket elements 8, 9 relative to each other is shown in Fig. 5 indicated by arrows. Fig. 5 shows the bracket elements 8, 9 adjusted relative to each other. This allows the span S of the anchoring elements 21, 22 to be reduced in the direction of the longitudinal extension of the long goods holder 10, so that the bracket clamp 1 has a reduced span Sr in the area of ​​its anchoring elements 21, 22, in order to be able to insert it into the assembly opening 5 of the rung 3. The spans Sr and S of the anchoring elements 21, 22 are shown in the Fig. 6 and Fig. 7. The position of the two bracket elements 8, 9 of the bracket part 7 of the bracket clamp 1 with the cable 2 passing through its long goods holder 10 during the process of assembly on the rung 3 is shown in Fig. 6. The anchoring elements 21, 22 have for this purpose end-side adjusting bevels 30, 31, which interact with the edges formed by the legs 6, 6.1 with the upper side of the rung 3, so that the bracket elements 8, 9 are automatically adjusted, solely by a translational movement of the bracket clamp 1 in the direction of the mounting opening 5. This adjustment of the bracket elements 8, 9 against each other to guide their anchoring elements through the mounting opening 5 takes place against the force of the compression spring 13 acting on the upper side of the bracket elements 8, 9 via the adjusting plate 14, so that when the anchoring elements 21, 22 are guided through the mounting opening 5 of the rung 3, they automatically move into their position engaging behind the legs 6, 6.1 and thus the mounting opening 5, as in Fig. 7. In this position, the clamping screw 12 is then tightened in order to fix the fastening clamp 1 with the cable 2 guided through its long goods holder 10 to the rung 3.

[0025] Fig. Figure 8 shows another clamp 1.1, which is designed in the same way as clamp 1 in the preceding figures. Therefore, the above statements regarding clamp 1 apply equally to clamp 1.1. Therefore, only the differences between clamp 1.1 and clamp 1 will be discussed below.

[0026] The clamp 1.1 is designed as a grounding clamp. For this purpose, the pressure plate 11.1 of this clamp 1.1 has rows of penetrating elements 32 on its underside, pointing toward the long-goods holder 10.1. The rows of penetrating elements 32 consist of several penetrating elements arranged in a row, each forming a point. The planes of the rows of penetrating elements 32 are slightly inclined toward each other in the direction of the long-goods holder 10.1. The pressure element 11.1 is further designed to have two leg openings 33, 33.1, through which the legs 19.1, 20.1 of the clamp elements 8.1, 9.1 extend. An electrical earthing conductor, arranged under an outer insulation of an electrical cable, is contacted via the penetration bodies of the penetration body rows 32 when the clamp 1.1 is attached to a supporting structure, in turn by a rung 3.1 in Fig.8. In addition to the pressure plate 11.1 with its rows of penetration bodies 32, the U-clamp 1.1 also has a support element 34, which is arranged between the electrical cable 2.1 to be fastened and the upper side of the rung 3.1. The support element 34, in turn, also carries two rows of penetration bodies 35, so that when the U-clamp 1 is tightened, this and the rows of penetration bodies 32 of the pressure plate 11.1 are pressed from opposite sides into the sheath insulation of the electrical cable 2.1. At least the U-clamp elements 8.1, 9.1, the pressure plate 11.1 and the support plate 34, like the rung 3.1, are electrically conductive, at least to the extent that this is sufficient for earthing purposes. The support member 34 also has two leg openings 36, 36.1, through which the legs 19.1, 20.1 extend. Via the leg openings 33, 33.1 of the pressure plate 11.1 and those of the support member 34, the legs 19.1, 20.1 are guided with regard to their adjustability.

[0027] The invention has been described using exemplary embodiments. Without departing from the scope of protection described by the applicable claims, numerous further embodiments for implementing the inventive concept will become apparent to those skilled in the art without the need for further explanation within the scope of these statements.
