    description
    Field of the Invention The invention relates to a three-legged cable console having a support arm for supporting at least one cable or a cable rack. The invention also relates to an installation of such a cable console on a wall.
    Background of the Invention Cable trays are used to lay electrical cables, for example along or even between walls, floors or ceilings of buildings, tunnels or galleries. Likewise, cable consoles are e.g. Used in technical systems and large machines to transfer cables between different plant or machine parts.
    For example, DE 8 420 906 U1 describes a cable console for mounting on a sloping wall. For this purpose, the console is angled in the vertical direction at opposite ends with equal but oppositely directed angles corresponding to the angle of inclination of the wall and bolted to the wall there.
    JP 54 115 796 (A) describes a console with a leg for laying cables, which is connected via a pivotally connected to another leg. Here it is provided to screw both legs to a wall.
    SUMMARY OF THE INVENTION [0005] The inventor has recognized that there is therefore a need for a cable console which can be mounted flexibly on (differently) inclined walls with the least possible installation effort. This object is achieved by the present invention.
    One aspect of the present invention relates to a cable console with a support arm for carrying at least one cable or a cable rack. The cable console is equipped with three legs for mounting the cable console on one wall. Here, a first leg is adjustable in length and set up as a tie rod for attachment of the cable console on the wall. Also, the first leg is pivotally mounted. On the other hand, a second and a third leg are each set up as a support for fixing the cable console against the wall without fixing.
    Another aspect of the present invention relates to an installation with a wall and at least one such cable console. Here, the at least one cable console is mounted on the wall by the first leg is attached to the wall. By contrast, the second and third leg of the cable console are fixed to the wall during installation.
    General description of the cable console and its embodiments [0008] The following description is to be understood as referring to the cable console and also to the installation. The cable console is also referred to below as the "console". The installation comprises the assembled state of the at least one console on an inclined wall. Hereinafter, unless otherwise stated, the slope of the wall in each case the inclination at the mounting location of the console on the wall referred to, relative to the horizontal, with 0 ° refer to a horizontal floor and 180 ° to a horizontal ceiling. For a better understanding of the console, the installation and optional configurations are also explained below with reference to the assembly or on the basis of the mounted state of the console on the wall.
    In the cable console of the support arm for carrying one or more cables and / or for example, one or more cable bundles, cable channels, cable trays or cable trays is provided. In addition, pipes or other cables can be worn through the cable console. For a simpler presentation, however, the following description, unless otherwise stated, is formulated by way of example only with reference to a cable.
    This is true, as I said, equally to the installation. In some embodiments, the installation includes a plurality of spaced along the wall mounted brackets, the cable is placed in each case on one, on a part of or on all consoles.
    In order to prevent about unintentional slipping or slipping of the cable from the support arm, it is provided in some embodiments that the support arm in the assembled state of the console has a substantially horizontally oriented portion, for supporting the cable, such as for hanging up and supporting of the cable is provided. This is also referred to below as a horizontal orientation of the console.
    The console is equipped with a three-legged fastening device for mounting the console on the wall. For a stable position of the console on the wall, the three-legged fastening device forms a triangle with the distal ends of the three legs. As a result, in the mounted state unintentional pivoting movements of the console can be reduced, as can typically occur in a two-legged attachment. It is also possible to reduce mechanical stresses or even the risk of wobbling, which is typical for a four-legged fastening (which is overdetermined in terms of fastening), for example due to unevenness of the wall or due to length tolerances of the legs. In some embodiments, the distal ends of the three legs describe a substantially isosceles or substantially equilateral triangle.
    During assembly, the first leg is attached to the wall, thereby securing the console to the wall. For this purpose, the first leg is set up as a tie rod for attaching the console to the wall. It is therefore designed, in the mounted state, to apply tensile forces, e.g. originate from the weight of the console itself or by the weight of the optionally supported cable to transfer to the wall and to hold the console to the wall. Hereinafter, the first leg is also referred to as a "tie rod".
    On the other hand serve in the assembled state of the console, the second and the third leg as supports for supporting the console on the wall. The second and third leg are therefore hereinafter also referred to as "support legs", wherein they rest in the mounted state of the console without fixing to the wall. The support legs transfer certain portions of the weight forces mentioned on the wall, but not as tensile forces, but (essentially) as compressive forces.
    "Befestigungslos" is to be understood that the support legs are not fixed with respect to the transmission of tensile forces on the wall. However, in some embodiments, the support legs are secured against movement along the wall, such as by one or more stops, recesses or projections on the wall. By contrast, in other embodiments, the support legs are free-floating on the wall; For example, this is no further attachment or securing the support legs against sliding movements of the support legs along the wall provided, ie the support legs themselves are (except on the attachment of the tie rod) not secured against slipping along the surface of the wall. In other words, the tie rod is fixed to the wall, however, the support legs are not fixed (at least not with respect to the transmission of tensile forces away from the wall).
    As part of the assembly so it is sufficient to attach the distal end of the tie rod to the wall to secure the console to the wall, and indeed sufficient in terms of their function to carry the cable. This simplifies the assembly.
    According to the three-legged fastening device of the console this touches the wall in the assembled state at three separate locations, namely in the region of (the wall facing) distal ends of the three legs. In addition to these three points, in some embodiments, no further mechanical connection between the bracket and the wall is provided for attachment beyond.
    With regard to the tie rod, such a point is also referred to below as the attachment point, which may be e.g. is the position of a conventional anchorage of the tie rod on or in the wall. With regard to the support legs, these points are hereinafter also referred to as support points, which designate the position at which the support legs are supported on the wall.
    These points as well as the attachment point and the support points are not only to be understood as expansion-free points in the mathematical sense. Rather, the console and the wall each have (extended) contact surfaces, for example of the order of magnitude of square millimeters, square centimeters or alternatively square decimeters. In some embodiments, the tie rod and / or the support legs are each equipped with a foot plate at the distal end. In some embodiments, the distal ends of the tie rod and / or the support legs are rectangular (in their respective longitudinal direction) or bevelled, e.g. at an angle of 30 °, 45 ° or 60 °. In some embodiments, the support legs are equipped with a tip at their distal end.
    In some embodiments, the console is mounted on an arbitrarily inclined wall. In some of these embodiments, the slope of the wall is substantially 90 °, that is, the wall is vertical at the mounting location. Some embodiments relate to an installation in which the console is mounted on a substantially horizontal wall, such as a ceiling. Overall, corresponding configurations of the console are therefore equipped in terms of construction for attachment to such inclined walls.
    First, the operation of the three-legged fastening device is explained with respect to a stable position of the console on the wall. To ensure that the console rests in a stable manner against the wall when mounted, although it is not fastened to the support legs on the wall (in terms of the transmission of tensile forces), it is provided that tensile forces are applied to the tie rods (net) and over the support legs respectively (net) compressive forces are transmitted with respect to the wall.
    For this purpose, the focus of the console is arranged so that in the mounted state, a torque acts around the attachment point as a fulcrum, which causes the pressure forces in the support legs. As a result, the console (even with the non-attaching support legs) stably against the wall. Incidentally, this can act in the legs other forces, such as bending and / or shear forces. The legs are sized accordingly to withstand these forces.
    Incidentally, this mode of operation of the three-legged fastening device applies equally with and without the cable possibly carried by the bracket. With regard to the fastening device, the cable contributes to the weight force and thereby increases the forces acting in the legs substantially only in their magnitude. Although the amount of torque may increase when carrying the cable, but this direction does not change, as seen in the horizontal direction, the mutual spatial order of the center of gravity, the fastening supply point and the support points remains unchanged. In the support legs, therefore, only larger compressive forces act due to the cable, however, their directions do not change substantially, ie they remain compressive forces and are under no circumstances to tensile forces. Consequently, regardless of whether the cable is carried by the console or not, always compressive forces in the support legs. As a result, in both cases (with all three legs) the console rests stably against the wall.
    In some embodiments, viewed in the vertical direction, the attachment point is arranged (for non-horizontal walls) above the two support points. In other words, in this case the tie rod is arranged in the mounted state in the vertical direction above the two support legs. In addition, in these embodiments, the center of gravity of the console to the attachment point in the horizontal direction seen spaced, and away from the wall. Thus, a torque acts on the center of gravity, which acts around the attachment point as a fulcrum in the direction of the support points. Consequently, a compressive force is exerted in each case on the support legs on the wall in this case, so that the console is stable against the wall.
    Some embodiments relate to a "superimposed" mounting, ie the mounting on a wall with an inclination of less than 90 °, ie walls that represent an inclined plane and in which the console is figuratively speaking «on» the inclined wall mounted , Here, viewed in the horizontal direction of the center of gravity and the support points are arranged on the same side with respect to the attachment point, so that starting from the center of gravity, a torque acts around the attachment point as a fulcrum on the support points.
    Other embodiments relate to an "overhead" installation, ie the mounting on a wall with an inclination greater than 90 ° to including a horizontal wall (ceiling), ie walls that represent an overhang and in which the console figuratively spoken «under» the wall is mounted. Here, viewed in the horizontal direction of the center of gravity and the two support points are arranged on opposite sides with respect to the attachment point, so that even in these embodiments, starting from the center of gravity acting torque around the attachment point as a fulcrum on the support points.
    For vertical walls, the center of gravity of the console is seen in the horizontal direction «before» the wall and is thus spaced (in this direction) from the attachment point and the support points, which are located on the wall. Therefore, even with vertical walls, the torque acts from the center of gravity around the attachment point as an axis of rotation on the support points.
    In some embodiments, the console is mounted on a (at least at the installation site) deviating from the vertical inclined wall. In some embodiments, the wall is curved in the vertical direction and therefore has different slopes varying in height, such as in the case of a tubular tunnel wall or stud wall. In some embodiments, the wall at different locations has different slopes due to unevenness of its surface; for example, it is a wall of a cliff carved in rock or it has a surface of shotcrete.
    Consequently, in the various embodiments described above concerning different inclinations of the wall, the console is in each case stable against the respective wall.
    In order to vary a spatial orientation of the console relative to the wall, e.g. in order to align the console horizontally, (at least) the tie rod is adjustable in length. In some embodiments, therefore, only the tie rod, while in others the support legs are equipped adjustable in length.
    In the assembled state, the aspect ratios of the three legs determine the spatial orientation of the console relative to the (spatial) orientation of the wall at the installation site. Here, the length of the tie rod and / or the support legs, for example, before installation, in addition or alternatively in the already assembled state adjustable. Overall, the length adjustability of the tie rod and / or the support legs allows the console can be flexibly mounted on different inclined walls or at different mounting locations along a curved wall. The console can also be pivoted vertically and / or horizontally.
    Incidentally, it is difficult to comply with the attachment of the tie rod to the wall a certain angle, such as when drilling in walls. Also unevenness of the wall or the spatial orientation of a leg or the console affect an angle between the leg and the wall. In order to align the tie rod and / or the support legs relative to the wall or relative to the (remaining) console, the tie rods and / or the support legs are pivotally mounted on the console. In some embodiments, the console is (each) equipped with a bearing for the tie rod and / or the support legs, which has at least one degree of freedom, namely a rotational degree of freedom for pivoting the leg.
    Overall, the console can be aligned by means of the length adjustability and the pivoting of the tie rod and / or the support legs at the installation relative to the wall. Incidentally, in some embodiments, the two support points, ie the distal ends of the support legs, together in a horizontal plane below the attachment point, ie the distal end of the tie rod, arranged. Thus, due to the length adjustability of the tie rod or legs, the bracket can pivot up and down in a vertical plane.
    For example, if the console is inclined with respect to the wall, a distance between the bracket and the wall along the wall may vary. Accordingly, in some embodiments, the legs (from the outset, ie irrespective of the length adjustability of the tie rod or the support legs) different leg lengths, in some of these embodiments, however, the two support legs are the same length and therefore only the tie rod has a different length than the support legs.
    In view of the fact that at least the tie rods, in some embodiments, however, the support legs are adjustable in length, is below the length of a length-adjustable leg, unless otherwise stated, to understand its effective length at a middle position of the respective length adjustment. In other words, a leg that can be adjusted in length can be lengthened or shortened by half the stroke of its length adjustability starting from its "leg length". A length-adjustable leg thus has a maximum length, which is greater than «leg length» by half the stroke of its length adjustability. In addition, the actual leg length is the respectively set, ie instantaneous, but variable length of the leg.
    In other embodiments, the "leg length" is defined in terms of a different adjustment of the length adjustment, for example, the leg length denotes a maximum or a minimum effective leg length in terms of length adjustability of the leg or an off-center settings with respect to the hub. The following description is formulated for a simpler representation of the first-mentioned definition of the leg length, that is, based on a center position with adjustable legs. However, further embodiments or embodiments explained below result accordingly by using the alternative definitions of the leg length.
    To connect the console e.g. To mount on a substantially vertical wall, in some embodiments, all three legs have substantially equal leg lengths. However, such consoles can also be aligned horizontally, even in the case of walls inclined at a certain angle from the vertical, for example by adjusting the effective leg length of the tie rod and / or the support legs by means of their length adjustability, ie by enlarging or reducing them.
    For example, to change the distance of the support arm from the wall, in some embodiments, the support legs are adjustable in length. A uniform change in length of all legs makes it possible to vary the distance of the support arm to the wall and thereby maintain a spatial orientation of the console. Furthermore, in an installation with multiple consoles, the cable can be guided as straight as possible from console to console along the wall, even if the wall has bumps or protrusions.
    In some embodiments, the stroke of the length adjustability of the tie rod and / or the support legs is 5 cm, 10 cm or 20 cm.
    In some embodiments, the tie rod and / or the support legs are slidably mounted, for example relative to the support arm. In some embodiments, the tie rod and / or the support legs are equipped with a telescopic extension for length adjustment of the leg.
    In some embodiments, the tie rods and / or the support legs are each equipped with a threaded rod. For example, the threaded rod in a nut of the console (by a rotary motion) slidably mounted or the threaded rod is part of the telescopic extension of the leg.
    In the installation can be in some embodiments by length adjustment of the tie rod and / or the support legs, the spatial orientation of the console within an angular range of up to 10 °, 20 °, 30 °, 40 °, 50 °, 60 °, 70 Swivel ° or 80 ° in the vertical direction. Additionally or alternatively, in some embodiments, accordingly, the spatial orientation of the console within an angular range of up to 10 °, 20 ° or 30 ° pivot in the horizontal direction.
    In some embodiments, the support legs are pivotally mounted. For example, they are pivotable with respect to a degree of freedom, that is pivotable in a plane.
    In some embodiments, the tie rod and / or the support legs are pivotable with respect to two degrees of freedom, such as horizontal and vertical.
    In some embodiments, the console is equipped with one, two or three bearings, each allowing two degrees of freedom to pivot, wherein such a bearing is provided for the tie rod and / or one of the support legs. Such a bearing is for example a ball joint, which allows pivoting in the vertical and horizontal directions. In some embodiments, only the tie rod or alternatively all legs are pivotally mounted with a ball joint relative to the support arm.
    In some embodiments, the console has a support plate to which the three legs and the support arm are attached, approximately on opposite sides of the support plate. For example, the carrier plate is equipped with one or three bearings for pivoting the leg (s). In some embodiments, the support plate is threaded with one or three threads, e.g. Nuts, equipped for length adjustment of the tie rod and / or the support legs.
    In some embodiments, the support arm and the tie rod and / or the support legs are substantially aligned coaxially, for example, include the support arm and such a leg at an angle less than 30 °, 20 °, 10 ° or 5 ° or are substantially arranged in parallel.
    In some embodiments, the three legs are arranged perpendicular to the wall in the assembled state of the console. Additionally or alternatively, in some embodiments, the three legs are arranged horizontally. In some embodiments, the wall is vertical and the three legs are arranged both perpendicular to the wall and horizontally.
    Incidentally, in some embodiments, the tie rod is attached to the wall, for example by means of a substantially horizontal bore in the wall.
    In some embodiments, the tie rod is anchored in the wall during installation with a fire protection dowel. For this purpose, in some embodiments, the tie rod is equipped with a fire protection plug at its distal end.
    Some embodiments are equipped with a length-adjustable support arm. As a result, different distances between the cable to be supported and the wall can be set in the assembled state. The stroke of the length adjustability of the support arm is for example 10 cm, 20 cm, 30 cm or 50 cm. In some embodiments, the support arm has a telescopic extension.
    In some embodiments, the support arm is equipped with a fastening device for one or more lights. Except for laying cables, the console is hereby also set up to hold the lamp (s), such a lamp is electrically connected, for example, branch line on the cable.
    In some embodiments, the support arm (along its longitudinal extent, that is seen from the legs to its distal end) angled, for example, L-shaped. In some embodiments, the support arm has an angle of 30 °, 45 °, 60 °, 90 ° or 120 ° along its longitudinal extension, or it is altogether (optionally without being angled itself) at such an angle relative to the tie rod and / or or the support legs arranged. This simplifies, for example, the horizontal orientation of the console on walls with a horizontal inclination (for example a ceiling) or with an inclination of less than 45 °, 30 °, 20 ° or 10 ° to the horizontal.
    In some embodiments, the support arm is arranged pivotally relative to the legs and / or the support plate. In some embodiments, the support arm is equipped with a hinge to pivot it relative to the legs or to angle it, that is, to pivot only a certain portion of the support arm. In some embodiments, the support arm or this section in this case by up to 30 °, 45 °, 60 °, 90 ° or 120 ° pivot.
    In some embodiments, the wall (at the installation site) has an inclination in the range of 10 ° to 180 °, from 45 ° to 180 °, from 90 ° to 180 °, from 45 ° to 135 °, from 135 ° to 180 °, from 60 ° to 120 ° or from 150 ° to 180 °. Accordingly, in some embodiments, the console is flexibly configured for mounting under such slope regions of the wall, for example due to different leg lengths, length adjustability and / or pivoting of the tie rod and / or the support legs as previously explained.
    In order to vary the support arm relative to the mounting location of the console in an vertical direction in an installation, in some embodiments, the console is equipped with a height adjuster. This allows the lifting and lowering of the support arm, for example, with a total stroke of 2 cm, 5 cm, or even 10 cm. In some embodiments, the height adjuster is adapted to move the support arm relative to the support plate and / or the three legs, for example perpendicular to the tie rod and / or the support legs and / or for horizontal alignment of the console and / or to a longitudinal axis of the support arm.
    In some embodiments, the height adjuster comprises shims, which can be arranged on the support arm or removed from it as required. This allows the cable at different heights, at least relative to the legs in the assembled state of the console hang up and support.
    Incidentally, in some embodiments of the installation, the cable is directly on the support arm and is supported by this. In order to reduce sagging of the cable, in some embodiments, one or more cables are combined with and routed within a cable channel or with a cable tray, the cable channel or cable tray being in turn carried by the cable console.
    In some embodiments, the support arm for laying and supporting the cable is set up; however, the support arm is provided in other embodiments for a suspended mounting of the cable, such as a loop which wraps around the cable and which is attached to the support arm.
    In some embodiments, the console is essentially stainless steel. In some embodiments, the console is designed according to relevant fire safety requirements.

    DESCRIPTION OF EMBODIMENTS WITH THE DRAWING The exemplary embodiments described below are to be understood equally with reference to a cable console and also to an installation in which at least one such cable console is mounted on a wall 1.
    A first embodiment of an installation with a three-legged cable console is shown in Figs. 1a and 1b. The cable console (hereinafter referred to briefly as a console) is in this case attached to a wall 1 of a tubular tunnel, the wall 1 seen in the vertical direction (towards the console) is curved. Incidentally, the wall 1 passes seamlessly into a ceiling of the tunnel, that is to say the wall 1 runs over the bracket, as illustrated by the sectional representation of the wall 1 in FIG. 1 a. Incidentally, ceilings can be considered as (essentially) horizontal walls. At the installation site, the wall 1 has an inclination of about 120 ° and therefore forms an overhang at the installation of the console. 1a shows a side view in the direction of the (horizontal) alignment of the wall 1, that is to say along a longitudinal direction of the tunnel. FIG. 1b shows a side view of the installation rotated by 90 ° for this purpose, perpendicular to the wall 1. FIG. 1b thus shows a plan view of the wall 1.
    The console is equipped with a support arm 3 with a section 2 for laying and supporting one or more cables. Additionally or alternatively, in further embodiments, the support arm 3 carries a cable rack and / or a cable channel. Hereinafter, for ease of illustration, only one cable will be treated as representative of all sorts of objects which may be carried by the support arm 3, such as at least one cable, a bundle of cables, a pipe, a supply line, a cable rack and / or a cable duct.
    The support arm 3 is in the example shown in FIGS. 1a and 1b rod-shaped with a square cross-sectional profile. Other embodiments differ in that in them the support arm 3 has a circular or rectangular cross-sectional profile, a T-profile, an L-profile (sometimes referred to as a double T-profile), an L-profile or a U-profile, being rod-shaped in some of these examples.
    In the example according to FIGS. 1a and 1b, the console is aligned horizontally in the mounted state, which means that (at least) the horizontal portion 2 of the support arm 3 is aligned horizontally for carrying the cable. However, the support arm 3 according to FIG. 1 is provided in total, ie over its entire longitudinal direction (as viewed in the horizontal direction in FIG. 1) for placing and supporting the cable, and also horizontally there. Other embodiments differ in that the support arm 3 is additionally equipped with at least one lug, a groove, a hook, a web, a mandrel, a clamp, a fork and / or a loop to secure the cable against slipping. Incidentally, in some of these examples, the support arm is not horizontal, but obliquely aligned so that it forms an inclined plane. Here, the cable is e.g. by means of said measures, e.g. at least one nose, secured against slipping.
    For attachment of the three-legged console on the wall 1, a first leg 4 is fixed to the wall 1 in the embodiment according to FIGS. 1a and 1b, namely at a designated below as attachment point B point the wall 1. However, are based the remaining legs 5, namely the second and the third leg 5, without fixing against the wall 1 from, at locations of the wall 1, which are hereinafter referred to as support points A. The legs 5 are therefore also referred to as support legs 5 and incidentally are loose at their distal ends on the wall 1, since they are not attached to the wall 1, that is, they are not held with respect to tensile forces on the wall 1.
    In summary, the console is thus equipped with a three-legged fastening device and has in the mounted state, the console only a fixed point on the wall 1, namely in the attachment point B, in which the leg 4 is attached at its distal end to the wall 1. As a result, the console can be mounted with little installation effort on the wall 1 and in this case is (yet) stable on the wall 1, as explained below.
    A center of gravity S of the console is seen in the horizontal direction in the area of the support arm 3. Since the console (only) is fixed in the attachment point B on the wall 1, therefore acts in the center of gravity S attacking torque D to the attachment point B as a fulcrum , This results in a tensile force Fz in the leg 4, which is therefore also referred to below as the tie rod 4. In addition, pressure forces FD resulted in the two supporting legs 5 arranged below in the direction of the wall 1.
    As shown in the side view according to Fig. 1b, the tie rod 4 in the horizontal direction (ie along the horizontal alignment of the wall 1) is arranged centrally between the support legs 5. Also, the tie rod 4 is disposed over the two support legs 5. Therefore, the distal ends of the legs 4, 5 (thus also the attachment point B and the support points A) form an isosceles triangle, so that the console is stable against the wall 1. This also does not change the fact that the support arm 3 is possibly loaded by additional weight forces of the cable. This only increases the forces Fz and FD, but does not change the stability of the console (guaranteed by the triangle) on the wall 1. Consequently, the three-legged fastening device described causes the console to rest stably on the wall 1, although it does only a single point, namely at the distal end of the tie rod 4 at the attachment point B is attached to the wall 1. Other embodiments differ in that the distal ends of the three legs 4, 5 form a (general) non-isosceles (true) triangle or, alternatively, an equilateral triangle.
    Incidentally, in the embodiment shown in Figs. 1a and 1b, the legs 4, 5 and the support arm 3 are fastened together to a support plate 6. Here, the support plate 6 is disposed between the legs 4, 5 and the support arm 3 and connects those.
    As mentioned above, the console is mounted horizontally on the inclined wall 1 and closes at the installation with this an angle of about 30 °. According to the oblique course of the wall 1, the higher-lying tie rod 4 is shorter than the lower-lying support legs 5 executed, the latter being the same length. Thus, the console - despite the deviating from the vertical inclination of the wall 1 - aligned horizontally. Incidentally, it is also perpendicular to the flight of the wall 1, that is aligned in a (imaginary) horizontal plane perpendicular to the wall 1.
    Regardless of the different leg lengths of tie rod 4 and support legs 5, the tie rod 4 is also adjustable in length and also pivotally mounted with respect to the console, as illustrated by the arrows in Fig. 1a. Thus, the effective leg length of the tie rod 4 can be increased or reduced as needed.
    In further embodiments, in addition, the support legs 5 are adjustable in length and, accordingly, the console equipped with a length adjustment for these legs 5. Additionally or alternatively, in other embodiments, the support legs 5 are pivotally mounted on the console.
    In all embodiments, an angle between the tie rod 4 and the support legs 5 and, in addition or alternatively, an angle between the tie rod 4 and the support arm 3 can thus be set. For the horizontal alignment of the console, the tie rod 4 and / or the support legs 5 is adjusted by adjusting the length and pivoting during assembly. This also surface irregularities of the wall 1 or tolerances are taken into account with respect to the inclination of the wall 1 at the installation. In addition, the console can be flexibly adapted to different inclinations within a certain margin, ie inclination range, so that the console can be mounted on the curved wall 1 even at different mounting locations.
    However, the length adjustability of the tie rod 4 and / or the support legs 5 has certain limits, namely a maximum stroke of 5 cm, which results from the difference between the maximum and minimum length of the leg 4, 5 in the length adjustment. Other embodiments differ in that they have a maximum stroke in terms of length adjustment of 2 cm or 10 cm.
    Other embodiments differ in that, with respect to the wall 1, they are even higher, i.e. higher than the wall 1. further to the tunnel ceiling towards mounting locations are provided. Since there the wall has a greater inclination, in these embodiments, the difference in length between the tie rod 5 and the support legs 4 is correspondingly larger than in the previously described, in order to ensure a horizontal orientation of the console despite the wall more inclined there. Other embodiments, however, are for lower mounting locations, i. further to the tunnel sole, provided. For them, this difference in length is correspondingly lower than in the examples described above. In some embodiments, the ratio of the leg lengths of tie rod 4 and support legs 5 is about 1, 0.9, 0.8, 0.7, 0.5, 0.4, 0.3 or 0.2, wherein in some of these examples, the leg length of the tie rod 4 is correspondingly greater than that of the support legs 5. By contrast, in other examples, the leg length of the tie rod 4 is correspondingly shorter than that of the support legs 5. Further embodiments are provided for a mounting location where the wall is substantially vertical. With them, all three legs have 4, 5 identical leg lengths.
    In summary, therefore, the embodiment shown in Figs. 1a and 1b is adapted for mounting on an overhanging wall 1. As shown in Fig. 1a, in this case in the horizontal direction (and perpendicular to the alignment of the wall, ie in Fig. 1 from left to right), the attachment point B between the support points A and the center of gravity S of the console is arranged. Incidentally, in this embodiment, this is accompanied by the fact that the leg length of the higher lying tie rod 4 is shorter than that of the lower lying support legs 5. As previously described, this results in the torque D to keep the console stable on the wall 1.
    This differs from another in Fig. 2 as a side view schematically illustrated embodiment in that it is set up for a mounting location of the wall 1 with a lower slope than the vertical. Namely, at such a mounting location, the wall 1 forms an inclined plane "on" the console is mounted (ie lying and not hanging, as in the example shown in Figs. 1a and 1b). In other words, the wall 1 runs in the region of the mounting location under the console. Here, the inclination of the wall 1 at the installation of the console is about 45 ° to 80 °. Incidentally, the wall 1 in the embodiment is substantially flat, so not curved. Further exemplary embodiments differ from that according to FIG. 1 in that the walls 1 are likewise substantially planar in their case, that is to say they are not curved.
    In the embodiment according to Fig. 2, seen in the horizontal direction perpendicularly away from the wall, i. E. in Fig. 2 from left to right, the support points A between the attachment point B and the center of gravity S are arranged. Accordingly, in this embodiment, as described above, a torque D results around the attachment point B as a fulcrum, in such a way that the console due to pressure forces FD in the support legs 5 rests stable on the wall 1.
    FIGS. 3a to 3d show schematically in a side view (analogous to FIG. 1a) further exemplary embodiments. Some embodiments according to FIG. 3a differ in that the three legs 4, 5 are fastened directly to the support arm 3 or are mounted on it. These embodiments are therefore carrier plateless.
    In order to increase the stability of the console when applied to the wall 1 in the assembled state, in some embodiments, the triangle formed by the distal ends of the legs 4, 5 is enlarged by the legs 4, 5 diverge towards their distal ends , So are arranged obliquely to each other. Various variants are shown schematically in FIGS. 3b to 3d as a side view. Here describe the legs 4, 5 a (possibly skewed) truncated pyramid. In some embodiments, the tie rod 4 and / or the support legs are arranged simultaneously or independently of one another at an angle of 10 °, 20 °, 30 ° or 45 ° relative to a longitudinal axis of the support arm 3.
    Accordingly, as schematically illustrated in Fig. 3b, in some embodiments, all three legs 4, 5 are arranged at an angle to each other and also to the support arm 3. Here, the tie rod 4 is directed obliquely upward in the assembled state to its distal end, however, the support legs 5 are each directed obliquely downward towards its distal end. 3c and 3d differ from each other in that only the tie rods 4 or, alternatively, only the two support legs 5 are arranged obliquely in this way, while the other legs 4, 5 are horizontal or substantially parallel are aligned with the support arm 3.
    Incidentally, the embodiments shown in Figs. 3a to 3d are provided for mounting on a vertical wall by (starting from the horizontal orientation of the bracket shown), the distal ends of the legs 4, 5 in a (imaginary) vertical plane lie.
    Of these, further embodiments differ in that they are equipped for mounting on a wall 1 deviating from the vertical inclined wall. In some of these embodiments, the tie rod 4 projects beyond the support legs 5 (in the case of horizontal alignment of the bracket) in the horizontal direction. Alternatively, in other examples, the support legs 5 protrude above the tie rods 4 in this way. In other words, the distal ends of the legs 4, 5 lie in an (imaginary) plane that is oblique to the section 2 of the support arm 3.
    Incidentally, in the case of pivotable legs 4, 5, the previously described oblique arrangement represents a center position with regard to pivoting. Pivoting legs can therefore also be pivoted about this inclination around an additional angle.
    In some embodiments, a length-adjustable leg 4, 5 (ie, the tie rod 4 and / or the support legs 5) comprises a threaded rod 41. According to the embodiments shown in FIGS. 4a and 4b, length-adjustable legs 4, 5 are configured overall as a threaded rod. ie the threaded rod extends along the entire leg 4, 5. Further embodiments differ in that the threaded rod 41 is shorter than the length-adjustable leg 4, 5, for example 2 cm, 5 cm or 10 cm. Overall, in some embodiments, the length of the threaded rod 41 substantially defines a stroke of length adjustability.
    In some embodiments, the threaded rod 41, as shown schematically in Fig. 4a, mounted in a threaded hole 42 which is arranged approximately in the support plate 6 or in the support arm 3. When turning the threaded rod 41 thus the leg 4, 5 shifts relative to the support arm 3, that is, the effective length L of the leg 4, 5 is varied.
    In contrast, in some other embodiments, as shown schematically in Fig. 4b, the length adjustment of an adjustable leg 4, 5, a (threadless) through hole 43 which is arranged approximately in the support plate 6 or the support arm 3 and through which Leg 4, 5 protrudes. Here, the leg 4, 5 is equipped with a threaded rod 41 and two nuts 44, wherein the nuts 44 are arranged on both sides of the through hole 43 on the threaded rod 41. With the nuts 44, as shown by the arrow in Fig. 4a, the effective leg length change. Also, by locking the nuts 44, the leg 4, 5 can be locked in terms of its effective leg length and / or its spatial orientation (if the leg 4, 5, as explained below, is pivotable).
    In some embodiments, the tie rod 4 and / or the support legs 5 are pivotable up to a maximum angle of 10 °, 20 °, 30 °, 45 ° with respect to a (imaginary) longitudinal axis of the through hole 43. For this purpose, an inner diameter of the passage opening 43 is suitably dimensioned for a respective maximum angle, taking into account a depth of the passage opening (approximately thickness of the support plate 6) and an outer diameter of the leg 4, 5 in the region of the passage opening 43.
    In some embodiments, disk-shaped washers 45 are provided between the through-hole 43 and the nuts 44 along a pivotable leg 4, 5 disposed on both sides of the through-hole 43. So that the leg 4, 5 can pivot, in this case the nuts 44 are mounted with clearance.
    Among other things, other embodiments differ in that they are equipped with a ball joint as a bearing for a pivotable leg 4, 5, as shown schematically in Fig. 5b. The ball joint comprises two hemispherical washers 46. In this case, the washers 46 are equipped, for example, with a circular or slot-shaped opening through which the legs 4, 5 are guided. In these embodiments, the leg 4, 5 can vary in terms of its effective length and also vary in terms of its spatial orientation (by pivoting) and also lock by locking the nuts 44 in this regard.
    In some embodiments, the support arm 3 is adjustable in length, for example, it is set up with a telescopic extension. Fig. 6a shows schematically such an embodiment in which the telescopic extension is realized with an inner tube 61 and an outer tube 62. The telescopic extension makes it possible to flexibly adjust the distance between the section 2 of the support arm 3 for placing and supporting the cable to the wall 1 during assembly. Thus, unevenness or protrusions of the wall 1 can be compensated. For example, the telescopic extension for a maximum change in length of the support arm 3 (stroke) of 10 cm, 20 cm, 30 cm or 50 cm set.
    In some embodiments, the console has a height adjuster, such as by the support arm 3 is mounted vertically adjustable on the support plate 6. The support arm 3 is in this case in some embodiments by up to 2 cm, 5 cm or 10 cm displaced in the vertical direction. In some embodiments, the height adjuster is equipped with vertically arranged oblong holes 63 in the support plate 6, as shown schematically in FIG. 6b. The support arm 3 is screwed by means of these slots on the support plate 63 and thus height adjustable along the slots 63.
    Further embodiments differ in that the support arm 3, as shown schematically in FIGS. 7a and 7b, is L-shaped (angled) along its longitudinal direction. When mounting such consoles on a ceiling 1 (according to FIG. 7a) or on a relative to the horizontal by up to 10 °, 20 ° or 30 ° inclined wall 1 (according to Fig. 7b), thus the section 2 for laying and Supporting the cable arranged horizontally, that is in the above introduced, abbreviated way of speaking, the console is aligned horizontally. To ensure that also such consoles rest stably against the wall 1 or the ceiling 1, seen in the horizontal direction of the attachment point B between the center of gravity S of the console and the support points A is arranged. As a result, as described above, a torque D engages in the center of gravity S of the console, so that pressure forces are respectively transmitted to the wall 1 in the support legs 5. Thus, the support legs 5, i. also the console stable on the wall 1, while the console is fixed by means of the tie rod 4 on the wall 1.
    In some embodiments, the support arm 3 is equipped with a fixture 71 for a luminaire 72. In some installations, the light 72 is mounted on the support arm 3 and electrically connected to a cable carried by the support arm 3. Fig. 7b shows an example of such an embodiment. However, other embodiments deviating from FIG. 7b are also equipped in this way.
    In some embodiments, the tie rod 4 is fixed with a fire protection dowel 80 in a bore 81 of the wall 1. Thus, the tie rod 4, as shown schematically in Fig. 8a, secured against tensile forces and thus the console held securely on the wall 1 even under the action of fire. In some embodiments, the tie rod 4 is equipped with a foot 82 which is secured by screws 83 or dowels to the wall 1. Additionally or alternatively, in further embodiments, the support legs 5 are equipped with a foot at its distal end. In some embodiments, the foot 81 is disposed obliquely opposite a longitudinal direction of the leg 4, 5 at its distal end. In other embodiments, the distal end of the tie rod 4 and / or the support legs 5 are footless, and the leg 4, 5 is there rectangular or beveled (mitred) ending with its cross-sectional profile or rounded there. In some embodiments, the tie rod 4 is rod-shaped. For example, it has a circular, rectangular, U-shaped, I-shaped, L-shaped or T-shaped cross-sectional profile.
    In some embodiments, the console is heat resistant up to temperatures of 600 ° C, 800 ° C, 900 ° C, 1000 ° C or 1200 ° C carried out, in some of these embodiments for functional integrity of the console under the influence of such temperatures over a period of up to 10 minutes, 30 minutes, 60 minutes or 90 minutes.
    Some embodiments are made of stainless steel, such as grade V4A.
