[0036] FIG. 11a-j another exemplary mounting procedure

[0037] FIG. 1 shows an embodiment of a holding device 1 for a cable or pipe 28, preferably for a so-called radiating cable (radiating cables are electrical leakage waveguides which are used as elongated antennas).

[0038] The holding device 1 has a holding foot 2 for mounting the holding device 1 to a ground (e.g. cable cup, ceiling or wall of a buildingpreferably a tunnel or shaft, etc.). Mounting is carried out with the mounting side 4 of the holding foot 2, e.g. by inserting a fastening means into the first and/or second fastening opening 12, 13 and connecting it to the ground. Examples of fastening means are screws, dowels (especially metal dowels), nails.

[0039] A fastening device is provided for fastening the cable or pipe 28 to the holding foot 2, whereby the fastening device is arranged on a side 5 of the holding foot 2 facing away from the mounting side 4.

[0040] The fastening device 2 has a stand 3 connected to the holding foot 2, which is arranged at a lateral edge area of the holding foot 2, so that the side 5 facing away from the mounting side 4 is at least partially accessible in a direction normal to side 5. This simplifies the mounting of holding device 1 to the ground, the selected fastening means can be inserted directly into the first and/or second fastening opening 12, 13 without further measures (in particular without the use of adapters), and can be connected to the ground with a suitable setting tool (e.g. hammer, screwdriver, air- or powder-driven tools. The setting tool is located next to the stand 3.

[0041] The stand 3 defines a fixed distance from the fastening device for the cable or pipe 28 to the mounting foot 2. Of course the distance of the cable or pipe to the ground can be increased by using spacers which are arranged between the mounting foot 2 and the ground (preferably connected to the mounting side 4 of the mounting foot 2). For correct positioning of such spacers, the mounting foot 2 can have at least one mounting 21 for at least one positioning pin arranged on the spacer.

[0042] As it can be clearly seen in FIG. 1 or 2, the stand 3 can be designed like a truss, in this way, sufficient rigidity can be achieved with low material input to ensure the load-bearing capacity of holding device 1. However, the stand 3 can be sufficiently elastic to be able to deform elastically along its entire length, for example in the event of pressure surges (these can occur, for example, due to a train passing through a tunnel), and then to be able to return to its initial position. In this way, the holding foot 2 and a fastening means connecting the holding foot 2 to the ground can be largely protected against dynamic forces. Point load peaks of the holding device 1especially in the area of the fastening device for the cable or pipe 28 and in the area of the fastening meansas known from the prior art, can thus be avoided, since the dynamic forces are at least partially already absorbed in stand 3. The truss forms a spring-damper system. The stand 3 has two longitudinal struts 31, 32, which connect the mounting foot 2 with the fastening device. Several cross struts 33 run between these longitudinal struts 31, 32.

[0043] A further advantage of the accessibility of the side 5 of the holding foot 2, facing away from the mounting side 4, is the possibility of checking the safe mounting (e.g. visual inspection, checking with a torque wrench, etc.) and the possibility of any necessary reworking of the mounting. The easy accessibility of side 5 of holding foot 2 also offers advantages for demounting of the cable or pipe 28 from the ground that may be required without the need to disconnect the cable or pipe 28 from the fastening device for fastening the cable or pipe 28 to holding foot 2.

[0044] If the holding device 1 is mounted to the ground, the cable or pipe 28 can be pre-positioned on the holding device 1 using the pre-fixing 14. The cable or pipe 28 is clamped into the spring clamp 14 shown here with two resilient legs and can then be aligned axially and/or radially. In contrast to FIGS. 1 to 8, the pre-fixing 14 could also be of a different design, e.g. hook-shaped (then the cable or pipe 28 is not clamped but only inserted or it could be provided that only one of the legs of the spring clamps shown is spring-loaded.

[0045] If the cable is aligned as desired, the cable or pipe can be fastened to the holding foot 2 using the fastening device.

[0046] This is possible in a particularly simple way, if necessary even without tools. For this purpose, the bracket fastener fastening device has a first bracket 61 and a second bracket 62 articulated to the holding foot 2 (via the stand 3) via a joint 23. The free end of the second bracket 62 carries the opening 9 of the bracket fastener 7, and can be moved over the free end 8 of the first bracket 61 by applying pressure to the second bracket 62, and can thus be locked by the bracket fastener 7.

[0047] The free end 8 of the first bracket 61 a here designed with a tapering 18 to facilitate the insertion into the opening 9. For the same purpose, opening 9 of the bracket fastener 7 has two insertion chamfers 91, 92.

[0048] The pressure con be exerted without tools, for example, by applying one hand. According to the invention, a clamping aid 15 is provided, which provides a defined point of application. This can be done either manually (e.g. using a thumb) or using a tool (e.g. with a defined torque).

[0049] Of course, more than one joint 23 could also be provided. The joint 23 could be designed in another form e.g. as axial joint.

[0050] It is preferably provided that the joint 23, via which the second bracket 62 is connected to the holding foot 2, is designed as an elastic or plastic joint 23. With such a joint 23, the pivotability of the second bracket 62 is ensured by a local weakening of the cross-section of the second bracket 62 in the area of the joint 23 and the material properties of the bracket 62 itself.

[0051] The bracket fastener 7 can, for example, be designed so that at the free end 8 of the first bracket 61, a rippled surface is arranged, which interacts with a locking lug arranged in the opening 9 of the bracket fastener. Alternatively, at least one hole could be arranged on the first bracket 61, into which a pin arranged in opening 9 of the bracket fastener can be pressed. Alternatively, it could also be provided that the free end 8 of the first bracket 61 is designed without rippled surface, hole or the like, and that a limited movable element (e.g., wedge-shaped or spherical) is arranged in opening 9 of the bracket fastener, through which self-locking locking takes place after the free end 8 of the first bracket 61 has been inserted into opening 9.

[0052] In FIGS. 7 to 9 in particular, a device provided in this embodiment for attaching a non-combustible safety strap 11 to the holding device 1 can be recognised irrespective of whether the holding device 1 is mounted to a ground. The device for attaching the safety strap 11 is provided in addition to the fastening device for the cable or pipe 28. In the event of fire, the non-combustible safety strap 11 forms a fall protection for the cable or pipe 28, which prevents the cable or pipe from falling even if the holding foot 2, the stand 3 and the fastening device are destroyed. The device for attaching the safety strap 11 allows a defined course of the safety strap 11 along the holding device 1, and thus facilitatespreferably without toolsthe fastening of the safety strap 11 to itself.

[0053] In the embodiment shown, the device for attaching the safety strap 11 comprises two retaining clamps 20 (if necessary, only one retaining clamp 20 or more than two retaining clamps 20 could also be provided) and a recess 22 arranged on the mounting side 4 of the holding foot 2 (this is not absolutely necessary). Furthermore, a guide 19 for the safety strap 11 is provided, which is particularly visible in FIG. 1. An insertion aid 17 for safety strap 11 may also be provided.

[0054] The holding device 1 is preferably pre-assembled with the safety strap 11. The safety strap 11 is embodied in two parts as shown in FIGS. 7 and 8. The first section is arranged in the area of the holding foot 2, and is connected to the second, here V-shaped section, which runs in the area of the stand 3. The first section has openings aligned with the fastening openings 12, 13 of the holding foot 2, so that the non-combustible safely strap 11 and the holding foot 2 can be fastened simultaneously. The two free ends of the second section (one end of which is provided with a strap closure 10) are connected with each other after the cable or pipe 28 has been arranged, and would hold the cable or pipe 28 securely to the ground in the event of a failure of the bracket fastener (e.g. in the event of fire).

[0055] An alternative embodiment of the non-combustible safety strap 11 in one piece form is shown in FIG. 3.

[0056] The safety strap 11 is inserted into the recess 22 and the retaining clamps 20 even before mounting the holding device 1 to the ground and before pre-fixing the cable or pipe 28. The safety strap 11 is already correctly aligned and held relative to the holding device 1.

[0057] Then the holding device 1 is mounted to the ground. Then the cable or pipe 28 is prefixed. Then the safety strap 11 is guided around the cable or pipe 28, guided through the guide 19, and exits at the other side of the stand 3 via an outlet opening 24. In the area of the outlet opening 24 the safety strap 11 has a passage opening 25, so that the free end of the safety strap 11 can be connected to itself in this area. In this state, the safety strap 11 forms a loop surrounding the cable or pipe 28. Alternatively, the free end of the safety strap 11 could be hooked into the side of the safety strap 11. For the connection, the free end of the safety strap 11 in this embodiment has a claw-shaped design 26. The claws of the tree end can reach behind the safety strap 11 in the area of the passage opening 25 (see FIG. 9b and 9c). Another embodiment of the connection (e.g. gluing, riveting, etc.) would be imaginable.

[0058] The passage opening 25 may have a widening to facilitate the insertion of the claws, with a slot-shaped section following the widening. It may be provided that the widening can be closed by a bendable safety lug 27 when the claw is in the slot-shaped section.

[0059] In the embodiment shown, safety strap 11 has a prefabricated angled shape.

[0060] Openings (here on the angled leg) are provided, which are aligned with the first and second fastening openings 12, 13 arranged on holding foot 2, for a passage of the fastening means.

[0061] If the safety strap 11 is to be galvanically separated from the fastening means, sleeves or washers made of an insulating material can be arranged in the area of the openings of the safety strap 11, which allow the fastening means to pass through. These can be embodied in one piece with the holding foot 2. Alternatively, the sleeves or washers can be inserted.

[0062] The non-combustible safety strap 11 canas is known per seconsist of metal or ceramics, for example.

[0063] FIG. 9a and 9b show a safety strap 11, as it is prefabricatedly provided to the fitter. FIGS. 9c, 9d and 9e show the completely mounted safety strap 11 in different views with the holding device 1 blanked out.

[0064] In the embodiments shown, the safety strap 11 runs with a distance to the cable or pipe 28 formed by the material of the holding device 1, which is particularly advantageous when using a metallic safety strap 11 and the cable is designed as a radiating cable, because this reduces interference of the radiation of the radiating cable by the metallic safety strap 11.

[0065] The fixing device for the cable or pipe 28 can have at least one positioning groove 16 for positioning the cable or pipe correctly on the holding device 1, if the cable or pipe 26 is provided with at least one positioning bead.

[0066] A first exemplary mounting procedure without using a metallic safety strap 11 is shown in FIG. 10a-f. It can be seen how the cable or pipe 28 to be fastened is first held by the pre-fixing 14 before the bracket fastener 7 is closed by applying pressure to the clamping aid 15.

[0067] A second exemplary mounting procedure using a metallic safety strap 11 is shown in FIG. 11a-j. The metallic safety strap 11 used here has a double-sided toothed section at its free end, which can easily be bent over. After inserting the free end into the passage opening 25, the free end is bent over to prevent the free end from slipping out of the passage opening 25. The two teeth located in the area of the passage opening 25 are thus aligned transversely to the passage opening 25 (cf. FIG. 11j), and lock the free end of the metallic safety strap 11 relative to the passage opening 25.

[0068] The constructive measures shown together in the figures can also be provided independently of one another or in any combination.
