Description

The invention relates to a bracket for rails, in particular for rails of monorails with preferably electrically powered trolleys, which bracket can be fastened at one end to a stationary support structure and is formed at its other end to accommodate the rail, which rail preferably has an upper and a lower rail head with a U-shaped cross-section including an open channel to the other rail head and a rail web connecting the rail heads, the web of the upper rail head preferably being designed on the outside as a running surface for rollers and idlers and flanges of the rail heads as guide surfaces for guide rollers of the running gear.

In practice, the rail is attached. the bracket and its attachment to the support structure in a variety of ways. For example, from DE-PS 30 19 301 a holder in the form of a bracket with a horizontal bracket arm is known, which has at its free end two block parts formed on both sides of the bracket arm, which in the defined by the two rail heads and the rail web, essentially omega - Shaped space for positive support of the free flanges of the rail heads protrude up to a stop, which of a clamping plate adjoining the free flanges and connecting the two block parts is formed. Within the omega-shaped space, two counter plates are inserted on both sides of the bracket arm, which rest against the free flanges on the channel side and are screwed to the outer clamping plate.

In order to be able to use these counter plates at any point on the rail, their height and width is less than the distance between the horizontal webs or between the free ends of the free flanges of the rail heads. For the same reason, the thickness of the counter plates is less than the distance between the channel-side surfaces of both flanges. As a result, the counter plates tend to tilt in two directions during assembly of the travel rail to the bracket, which causes the in them and. bores in the outer clamping plate for receiving the fastening screws are rarely in line. This leads to the time-consuming and laborious assembly of the rail on the bracket. This process is further complicated by the fact that the free flanges of the rail heads must run exactly perpendicular to the surfaces of the block parts that support them when they are inserted into the omega-shaped space of the rail. Otherwise it is not possible to hang the rail on the bracket. Another disadvantage is that very tight tolerances in the manufacture of the running rail and the block parts as well as the holes for the fastening screws have to be observed, since otherwise no positive support of the free flanges of the running rail on the block parts or screwing of the counter plates and the block parts is possible .

From DE-OS 20 12 317 a further holder in the form of a U-shaped bracket is known, the upper bracket arm of which is expanded in a plate-like manner and has two elongated holes arranged on a bolt circle and arcuately with the radius of the bolt circle over a length of π / 2.

A U-screw attached to the supporting structure is used to suspend the holder, the threaded legs of which penetrate the elongated holes from above and on the end portions of which protrude from the underside of the plate-shaped extension, nuts for supporting the holder are screwed on from below. A screw arranged in the center of the bolt circle serves to additionally fasten the holder to the supporting structure. The bracket fastened in this way can be rotated with respect to the supporting structure by any angle up to a maximum of 90 °, the length of the elongated holes. In order to enable a further rotation, a second holder is provided, the arcuate elongated holes of which are offset by 45 ° with respect to the elongated holes of the first holder. As a result, two different brackets are required in order to be able to turn the travel rail by an angle of no more than 135 ° with respect to the supporting structure. A rotation of the holder by an angle from 90 to 135 ⁰ turns out as a result time-consuming and cumbersome, a rotation of more than 135 ° is not possible.

From DE-PS 22 45 862 a further holder for connecting rails with double T or U profile with different widths of the horizontal flanges is known. Here, a circular connecting disc with a diameter corresponding to the width of the larger horizontal flange is arranged between the mutually facing horizontal flanges of both rails to be connected. On its outer circumference, this connecting disc has a circumferential, upwardly open groove in which clamping claws which produce the connection to the horizontal flange of the lower rail engage. The connection to the horizontal flange of the upper rail is made by further screwed into holes in the connecting disc Clamping claws, the distance between which is necessarily smaller than the diameter of the connecting washer.

Although this connection allows the lower rail to be rotated through 360 ° with respect to the connecting disk fastened to the upper rail, it is necessarily designed as an unstable two-point fastening due to the diametrically opposed clamping claws. Another disadvantage is the need to support the lower rail during rotation, otherwise the clamping claws would get stuck in the groove of the connecting disc. In addition, this connection is limited to the use of rails with horizontal flanges of different widths. Furthermore, only one specific combination of two rails can be connected with a connecting disc with regard to the width of the horizontal flanges. The outside diameter of this connecting disk must namely be adapted to the width of the horizontal flange of the lower rail and the spacing of the holes for the clamping claws to the width of the horizontal flange of the upper rail.

From the much later published DE _- OS 31 13 786 a holder for rails is known which can be adapted to different width horizontal flanges of rails of the supporting structure. This advantage is, however, paid for with the disadvantage that the rotation of the holder relative to the supporting structure has to be dispensed with entirely.

It is an object of the invention to further develop a bracket of the type mentioned at the outset in such a way that the running rail can be hung from the supporting structure in a simple, quick and reliable manner in any position relative to the supporting structure.

This is achieved in that the holder has a plate with elongated holes arranged on a bolt circle and formed in a circular arc in accordance with the radius of the bolt circle, a counterplate which can be fastened to the supporting structure by means of fastening means and with through holes arranged on the bolt circle, and into the elongated holes and through holes for connecting the plate to the counter plate has connecting elements which can be used independently of one another, and that the through bores and the elongated holes are designed in terms of number and length in order to achieve a congruent alignment of at least three through bores with at least two elongated holes in any angular position when the plate rotates with respect to the counter plate.

The plate and thus the running rail can be rotated through 360 ° in relation to the counter plate attached to the supporting structure. The counter plate has more than three through holes, which are arranged in combination with the length of the elongated holes, such that when the plate is rotated relative to the counter plate from an angular position in which, for example, three through holes are aligned with the elongated holes, that is to say free to insert of connecting elements, each of these through holes, which is covered as a result of the rotation by the web parts of the plate arranged between the elongated holes, is replaced by a previously hidden through hole which has become free during the rotation. In other words, there is already an angular position in which, for example, one of the three free through bores provided with inserted connecting elements has reached the end of an elongated hole. a fourth through hole at the beginning of an elongated hole, so that a connecting element can be inserted into this through hole. That in the on Connecting element inserted at the end of the elongated hole which has reached the other through-hole is now removed in order to enable the plate to rotate further with respect to the counter-plate.

At the same time, since compensation is possible by rotating the plate with respect to the counterplate, the latter can be rotated with respect to the supporting structure, which enables adaptation to supporting structures of different dimensions. When using, for example, two fasteners, e.g. on the horizontal flange halves. on both sides of the vertical web of a profile rail of the supporting structure, this profile rail can have a width corresponding to the distance of the fastening means if an imaginary connecting line between the two fastening means runs normal to the longitudinal direction of the profile rail. If the counter plate is to be fastened to a profile rail with a narrower horizontal flange, the counter plate is simply rotated relative to the profile rail so that the imaginary connecting line between the fastening means runs at an angle to the longitudinal direction of the profile rail. The smaller the angle enclosed by the imaginary connecting line between the fastening means and the longitudinal direction of the profile rail, the narrower the profile rail used can be. The plate is rotated relative to the counter plate by the same amount of angle with the opposite direction of rotation, so that the direction of the rail does not change.

The combination of the above features ensures that the plate and thus the travel rail can be rotated through a full 360 ° and is fastened in every angular position with a reliable, stable 3-point connection to the counter plate and thus to the supporting structure. The rotation can be carried out continuously without removing the plate from the counter plate and without supporting the travel rail from below. In the same simple and quick way it is Adaptation to supporting structures of different dimensions guaranteed.

The adaptation to support structures of different dimensions can be improved in that the counterplate is formed on the half-straight lines running outside the bolt circle of a straight line intersecting the bolt circle, each with a bore for receiving the fastening means.

The 3-point attachment of the bracket to the supporting structure in any angular position is advantageously achieved by providing two elongated holes and five through holes evenly distributed over the circumference of the respective hole circle, the arcs of a circle between the elongated holes being equal to the arcs of a circle between the through holes. The same effect can also be achieved with four elongated holes and eight through holes.

Another measure to solve the problem consists in an inventive manner that at least one receiving element for the rail is attached to the bracket and can be arranged in each of the channels of the rail heads and brought to the respective web and / or the flanges for play-free contact.

The internal dimensions of the channels are larger than the dimensions of the receiving elements, so that the latter easily and quickly; can be arranged within the former. This can be done, for example, by inserting the receiving elements fastened to the holder from the end face of the running rail or from rail sections into the channels and by subsequently shifting in the longitudinal direction of the running rail to the desired pick-up point. Only after reaching the desired pick-up point does each pick-up element in the vertical and / or horizontal direction become play-free contact with the respective rails brought head, whereby a reliable fastening of the rail on the bracket is achieved. Another advantage of this measure, which is inventive per se, is that the production of the receiving elements and / or the channels can be carried out with greater manufacturing tolerances than in the prior art.

By combining this measure, which is claimed by claim 5, with the features of claim 1, a holder can be created which enables the fastening of the running rail in a simple, quick and reliable manner at any point along its length and in any angle. position relative to the supporting structure.

In order to be able to insert the receiving elements directly from the omega-shaped space into the channels at the desired receiving point, the receiving element assigned to the lower and / or upper rail head is advantageously detachably attached to the holder.

The receiving elements are preferably arranged on the holder at the free ends of the receiving flanges of a U-shaped receiving head which run normal to the plane of the rail web. Thus, among other things, the omega-shaped space of the running rail can be kept free for accommodating supply and control devices which no longer find space on the other side of the running rail.

The receiving flanges and the web part of the receiving head are preferably detachably attached to one another or releasably on the holder. This makes it possible to exchange mounting flanges or mounting heads to adapt to different load cases, so that, for example, several mounting elements with larger or smaller mutual distances or a single mounting element with larger or smaller length measured in the longitudinal direction of the rail can be arranged within each channel.

According to a development of the invention, the receiving element arranged in the channel of the lower and / or upper rail head can be braced with the web of the respective rail head. This can be done, for example, by means of an adjustable threaded bolt, which connects the receiving element and the holder to one another and presses the former against the web while supporting the latter.

However, according to an advantageous embodiment of the invention, it is also possible to clamp the receiving element by means of at least one wedge that can be inserted into the channel in the longitudinal direction.

In this context, it is expedient to design the wedge to protrude out of the channel with the point of its smallest height dimension. The wedge can then preferably be designed as a receiving element. For secure fastening, it is advantageous to connect the wedge to the receiving element or the receiving head in a form-fitting manner by means of a tongue and groove arrangement.

According to a development of the invention, the wedge or the receiving element for abutment against the flanges of the respective rail head can be spread. For this purpose, the wedge or receiving element can have through openings in a known manner with or without cone bushings and expansion screws which can be screwed into them.

At comparatively low loads, the receiving elements can consist of plastic material with high damping properties with sufficient strength. This is particularly beneficial for improving sound insulation.

According to a further development of the invention, the transition from the flanges of the rail heads to the rail web connecting them can each be designed as a slope that moves away from the plane of the free flanges of the rail heads with increasing approach to the rail web. This makes it possible to form the receiving elements in the region of the transition from the flanges to the rail web with a contour adapted to the incline, so that the contact surface of the receiving elements on the running rail is enlarged.

The adaptability of the system created hitherto can be increased further in that the flanges arranged on the same side of the rail heads and the rail web connecting them lie in one plane.

Such an arrangement can be developed for very high loads by symmetrical formation of the running rail to the rail web. In this context, it is advantageous to use the receiving elements by designing the appropriate length to connect adjacent rail sections of the running rail and at the same time to align adjacent rail sections on the rail joint.

Advantageously, the holder has essentially the shape of a U-bracket, on the lower bracket arm of the receiving head and on the upper bracket arm the plate are arranged.

Preferably, in order to increase the static friction and thus in particular the forces which can be transmitted in the longitudinal direction of the rail, the outer surfaces of the receiving elements or of the wedges assigned to the flanges of the rail heads are roughened.

Among other things, this can take the form of knurling. In this case, the receiving elements or wedges are preferably made of a material with greater hardness than the flanges of the rail heads. When spreading, this knurling is then pressed into the flanges, creating an additional positive connection.

The invention is described in more detail below with the aid of a few exemplary embodiments and with reference to the accompanying drawing.

1 shows a holder 2, fastened with its upper end to a profile support 1 of a support structure (not shown), for a running rail 3, a monorail overhead conveyor with electrically driven trolleys, not shown here.

The running rail 3 consists of butt-assembled rail sections, each of which has an upper rail head 4, a lower rail head 5 and a vertical rail web 6 connecting both. Both Sehiene heads 4,5 are each formed as a U-profile with a horizontal web 7 and two vertically aligned, mutually parallel flanges and arranged in such a way that the channels 8 enclosed by them are open to the other channel. In the present exemplary embodiment, the rail web 6 connects the flanges 9 shown on the right-hand side of FIG. 1. The free flanges parallel to this are identified by the reference number 10 provided. The flanges 9 have a larger thickness dimension than the flanges 10 and than the rail web 6. The latter is arranged approximately in the vertical center plane of the flanges 9 and connected to them by conical transitions 11. The trapezoidal groove 12 thus formed on the side of the running rail 3 facing away from the channels 8 is provided for receiving busbars 13 for the electrically driven running gears. On the opposite side of the running rail 3, an essentially omega-shaped space 14 is defined by both rail heads 4, 5 and the rail web 6, the channels 8 being components of this space. The channel-side bevels of the conical transitions 11 are provided with the reference number 15.

The surface of the web 7 of the upper rail head 4 serves as a tread 16 for running and idler rollers of the trolleys. The outer sides 17 of the flanges 9 and / or 10 of one or both rail heads 4, 5 serve as guide surfaces for guide rollers of the trolleys.

In the present exemplary embodiment, the holder 2 comprises a U-bracket 18 with a vertical bracket web 19, a lower horizontal bracket arm 20 and an upper bracket arm 21 parallel thereto, the upper side of which is expanded to form a horizontally oriented plate 22. Connecting elements in the form of cap screws 23 represent the connection between the plate 22 and a counter plate 24 parallel thereto, which in turn are fastened to the two halves of a lower horizontal flange 26 of the profiled beam 1 with fastening means 25 in the form of screwed clamping claws. The U-bracket 18 has a double-T cross-section.

A U-shaped receiving head 27 with a vertical web part 28 and a lower and an upper receiving flange 29 and 30 is provided for receiving the travel rail 3 on the holder 2. The vertical web part 28 is welded to a-n free end of the bracket arm 20. Both receiving flanges 29, 30 extend in a horizontal direction into the omega-shaped space 14 of the running rail 3 and end at a short distance from the rail web 6 near the conical transitions 11. In their corner regions, the receiving flanges 29, 30 still have receiving elements to be described, which engage in the channels 8 of both rail heads 4,5.

2, the lower part of the U-bracket 18 is shown with the mounting head 27 attached to it, without the travel rail 3 and without mounting elements on the lower mounting flange 29. In the corner areas of the two receiving flanges 29, 30 formed with ear-shaped projections, a bore 31 is provided for fastening elements for the receiving elements. Only the bores 31 in the lower receiving flange 29 can be seen, since they are hidden in the upper receiving flange 30 by the receiving elements. These are receptacle elements 32 which can be expanded to the flanges 9, 10 and which, as can clearly be seen, are shown in the expanded state.

Fig. 3 shows an enlarged sectional view of the formation of. Recording elements and their arrangement in the channels 8 of the rail. In contrast to the travel rail shown in FIG. 1, this travel rail has two flanges 9, the outer sides 17 of which lie in one plane with the side of the rail web 6 that connects them to the receiving head 27. The inclusion of this rail provided with the reference numeral 33 on the receiving head 27 takes place with the spread shown in FIG. 2 baren receiving elements 32. These each have a cross-section with a truncated pyramid 34 with a rectangular base surface and a rectangular section 35 extending the respective receiving flange 29,30. The height dimension of the receiving element 32 is selected such that it extends from the web 7 of the respective rail head 4, 5 to the point which, starting from the rail web 6, represents the beginning of the slope 15 of the conical transition 11. The height of the cuboid section 35 corresponds to the vertical dimension of the flange 9, 10. The side surfaces of the truncated pyramid 34 are of the same length as the bevel 15 and fit snugly against it. Each receiving element 32 is provided with a vertical slot, a bore 36 is expanded. A self-locking conical bushing 37 is arranged in the bore 36 in the region of the cuboid section 35. An expansion screw 38 with a cylindrical thread is screwed into the bore 36 and the conical bushing 37, so that the side walls of the cuboid section 35 lie non-positively on the inside of the flanges 9, 10. The expansion screw 38 passes through the bores 32 in the respective receiving flange 29, 30 and thus simultaneously represents the fastening element already mentioned for the receiving element 32 on the receiving flanges 29,30.

To fasten the running rail 3.33 to the holder 2, the receiving elements 32 are fastened to the upper receiving flange 30 of the receiving head 27 by means of the expansion screws 38, which, however, are screwed into the internally threaded holes 36 only to such an extent that the receiving element does not expand . It is advantageous here to also provide the bores 31 with an internal thread, so that the receiving elements 32 are prevented from evading when inserted into the channels 8. The lower mounting flange 29 is free. The corresponding recording elements 32 are already inserted in the channel 8 of the lower rail head 5. Then the rail 3, 33 with its upper rail head 4 or the associated channel 8 is placed on the mounting elements 32 fastened to the upper mounting flange 30 and pressed down until it abuts the web 7. The fact that the receiving flanges 29, 30, as already mentioned, end at a distance from the rail web 6 in the inserted state, makes it easier to hang in the running rail 3.33. Then, if necessary, the receiving elements 32 are moved in the channel 8 of the lower rail head 5 until their conical bushings 37 are aligned with the bores 31 in the lower receiving flange 29. Then the expansion screws 38 are screwed through these bores 31 into the bores 36 and the conical bushes 37 until they stop. The expansion screws 38 partially screwed into the receiving elements 32 on the upper receiving flange 30 are also screwed in as far as they will go. The cuboid sections 35 are spread and brought to the respective flanges 9, 10 of both rail heads 4, 5 for frictional engagement. The side surfaces of the truncated pyramid 34 form-fit the slope 15. The spread receiving elements 32 used in this way can transmit high forces, in particular those which occur in the longitudinal direction of the running rail.

With rails that are exposed to lower loads, it is possible to use mounting elements that are made of plastic material with high damping properties and sufficient strength. In this case, for example, the conical bushing 37 can be omitted and, instead of the expanding screw 38 with a cylindrical thread, one with a conical thread can be used. It is easy to see that instead of the expandable receiving elements, those that cannot be expanded can also be used.

If both types of receiving elements are used, it is advantageous to attach the expandable elements to the upper receiving flange. It is also conceivable to use only one or three or more such elements instead of two receiving elements per receiving flange. For this purpose, mounting flanges or mounting heads of different lengths and with a different number of holes can be used.

At the same time it can be seen that the side of the rail web 6 facing the receiving head 27 is completely free due to the distance from the vertical web part 28 for accommodating additional supply and / or control devices which cannot be accommodated on the opposite side of the rail web 6.

The above statements also apply to the exemplary embodiment shown in FIG. 4. According to this, a travel rail 39 is fastened to the receiving head 27 by means of receiving elements 40. These receiving elements 40 correspond to the above-mentioned receiving elements 32 — the same parts are designated by the same reference numerals — but are designed to be cuboidal throughout over their entire height. In contrast to the above-mentioned rails 3.33, the running rail 39 is designed symmetrically to its rail web 6 and has an upper rail head 41 and a lower rail head 42, both of which each have two free flanges 10 and two channels 8. The remaining components are designated by the same reference numerals as the corresponding elements of the rails 3 and 33.

5, the travel rail 39 is held by means of receiving elements 43, which are formed in one piece with a receiving head 44. The latter is with its web part 28 at the free end of the lower. Bracket arm 20 of the bracket 2 screwed. Like the receiving head 27, it is U-shaped, but its horizontal receiving flanges 29, 30 are deflected at right angles in the region of the channels 8 of the travel rail 39 to form vertical extensions, which extensions represent the receiving elements 43. These receiving elements 43 are thus of the same length - in the longitudinal direction of the rail - as the receiving flanges 29, 30 and therefore, in contrast to the previously driven receiving elements 32, 40, have a greater length than height.

The distance between the channel-side inner surfaces of the webs 7 of both rail heads 41, 42 is greater than the distance between the support surfaces of the receiving elements 43 facing these inner surfaces. Head 41 associated support surface 45 (see FIG. 6) is parallel to the inner surface of the web 7. The lower support surface consists of two inclined surfaces 46 which run obliquely in the longitudinal direction, but which are parallel to the inner surface of the assigned web 7 in the transverse direction. Both inclined surfaces 46 are symmetrical to one another, ie their apex is located halfway along the length of the receiving head 44. They run in such a way that their distance from the upper bearing surface 45 is greater at the apex than at the two end faces of the receiving head 44. This course makes it possible To insert a wedge 47 between the inclined surfaces 46 and the associated web 7 from the end faces of the receiving head 44 so that the receiving head 44 and thus the receiving elements 43 are braced with the webs 7 of both rail heads 41, 42. The receiving head 44 thus braced in the vertical direction with the running rail can not only absorb large forces in the longitudinal direction of the rail, but also contributes to the stiffening of the running rail 39 in the transverse and vertical directions. As shown schematically in FIG. 6, each wedge 47 can be provided with a para on its section which projects in the inserted state on the respective end face of the receiving head 44 lel to the rail web 6 continuous longitudinal slot 48 is provided, in which an only schematically indicated spreading arrangement 49 is arranged. This expansion arrangement essentially consists of a slot extension with an inserted conical bushing and a screw-in expansion screw. 5 and 6, the greatest distance between the contact surfaces 45 and 46 is greater than the distance between the free ends of the flanges 10, so that the receiving head 44 is inserted into the channels 8 only from the ends of the respective rail sections Accordingly, the receiving elements 43 and the wedges 47 have little play in the transverse direction with respect to the respective rail head 41, 42.

FIG. 7 shows a receiving head 50 for receiving the running rail .39, which corresponds to the above-described receiving head 44 with the exception that the vertical extension 51 of the lower receiving flange 29 has a lower height than the corresponding vertical extension or the receiving element 43 (FIG. 5) has and is also provided with a recessed in the support surface 46 longitudinal groove 53. Correspondingly, the wedges 52 are formed higher than the wedges 47 described above and are additionally provided on their upper side with a longitudinal rib 54 which engages in the longitudinal groove 53 in a form-fitting manner. In Fig. 7, the boundary lines of the longitudinal rib 54 are drawn for the sake of clarity at a distance from the boundary lines of the longitudinal groove 53.

The height dimensions of the wedges 52 are such that they protrude from the channel 8 over their entire length in the inserted state. This means that the receiving head 50 can be inserted into the channels 8 at any point on the running rail 39 from its omega-shaped space 14 and that the wedges 52 take over the function of the lower receiving elements. The vertical extensions

In the present exemplary embodiment, 43, 51 lie against the bevels 15 of the conical transitions 11 of the rail 39.

These receiving heads 44 and 50 are particularly suitable for receiving the travel rail in the region of the joint between two adjacent rail sections, since they support the travel rail 39 over a relatively large length with their receiving elements 43 or the wedges 47, 52.

FIG. 8 shows, on an enlarged scale, the plate 22 formed on the upper side of the upper bracket arm 21 of the holder 2. The plate 22 is provided with four elongated holes 55 arranged on a hole circle L and of circular arc shape with the radius of the hole circle. These elongated holes 55 are arranged at a uniform mutual distance on the bolt circle and have the same lengths. The bolt circle arcs arranged between the elongated holes 55 are provided with the reference symbol LB. The plate 22 is circular.

9 the counter plate 24 is shown. It essentially has the shape of an elongated ellipse. Approximately in the areas of the ellipse focal points, a through hole 56 is formed for receiving a screw for fastening a clamping claw to the profile carrier 1 of the supporting structure (see FIG. 1). In the _medium-l older area of the counter plate 24 eight through holes 57 are formed which are arranged at equal mutual distances L _B L on the same hole circle on which the slots are 55.

The elongated holes 55 and the through bores 57 are provided for receiving the cap screws 23 which establish the connection between the plate 22 and the counterplate 24 (see FIG. 1).

On the upper side of the counter plate 24, hexagonal recesses 58 are formed which are assigned to the through bores 57. The pitch circle arcs LB between the through holes 57 are of the same length as the pitch circle arcs LB between the elongated holes 55.

10 and 11, the plate 22 and the counter plate 24 are connected to each other. For this purpose, the cap screws 23 are inserted from the underside of the plate 22 into the through bores 57 and the elongated holes 55. For the sake of clarity, the depressions 58 and the screw heads arranged therein are not shown in FIGS. 10 to 13. Only the shafts of the cap screws 23 are shown.

Each with its screw head of the underside of the plate 22 abutting head screw 23 are assigned three nuts, the uppermost, not shown, is seated in the hexagonal recess 58 and the lower abut against the underside of the counter plate 24 or top of the plate 22. Thus, the counter plate 24 and the plate 22 can be fixed at any desired distance from one another, while at the same time there is the possibility of achieving a certain inclination of the plate 22 with respect to the counter plate 24.

10, the plate 22 and the counter plate 24 are in a first angular position to one another. In this, the eight through bores 57 are arranged congruently with the elongated holes 55 and are therefore free to insert eight cap screws 23. Of course, fewer than eight cap screws 23 can also be used, the number of three preferably not being less than. As a result of the same length of the circular arcs LB between the elongated holes 55 and between the through bores 57, the latter are arranged at the ends of the elongated holes 55, as can be clearly seen in FIG. 10.

The travel rail 3 extends in a direction normal to an imaginary connecting line between the two through bores 56 in the counterplate 24. For a better understanding of the following explanations, the elongated holes 55 and the through bores 57 are clockwise with indices 1 to 4 and 1 to 8, respectively Mistake.

In the first angular position shown in FIG. 10, the through holes 57/1 and 57/2 are assigned to the elongated hole 55/1. A corresponding assignment applies to the remaining through holes 57/3 to 57/8 and elongated holes 55/2 to 55/4.

11 shows the plate 22 in a second angular position with respect to the counter plate 24, in which the travel rail 3 runs obliquely to the imaginary connecting line between the two through bores 56 in the counter plate 24. The plate 22 is rotated counterclockwise in the direction of rotation D. In order to enable this rotation, four of the eight cap screws 23 used are first removed, one from each slot 55. In the present exemplary embodiment, these are the cap screws which are arranged in the through bores 57 / 2.57 / 4 which are arranged in the direction of rotation D , 57/6 and 57/8. After loosening the uppermost nuts of the counter plate 24 from below on the head screws seated in the through holes 57 / 1.57 / 3.57 / 5 and 57/7, the rotation can take place in the direction of rotation D, the through holes 57/2 , 5774, 57/6 and 57/8 are covered by the areas 59 of the plate 22 arranged between the elongated holes 55. The through bores 57 / 1.57 / 3.57 / 5 and 57/7 with seated cap screws 23 are arranged in the middle of the respective elongated hole 55 after the turning process has ended. By simply tightening the uppermost nuts assigned to the counter plate 24, the plate 22 and the counter plate 24 become in the second Angular position mutually fixed.

With a further rotation in the direction of rotation D by the same angular amount of the previous rotation, an angular position is reached in which, as in FIG. 10, all eight through bores 57 are aligned with the four elongated holes 55. However, with the difference that the through holes 57/8 and 57/1 are now assigned to the slot 55/1. The assignment of the remaining through bores 57/2 to 57/7 and the elongated holes 55/2 to 55/4 is corresponding. It is easy to see that the plate 22 and the counter plate 24 are connected by at least four cap screws 23 in each angular position when rotated through 360 °.

In order to achieve a stable and reliable connection of the plate and counter plate during the continuous rotation through 360 °, other combinations of through holes and elongated holes in terms of number and length are also possible. It is also conceivable to connect adjacent through holes with one another so that Elongated holes arise in their place. Of course, it is also possible to form the through bores 57 in the plate 22 and the elongated holes 55 in the counter plate 24.

FIG. 12 shows a top view of the horizontal flange 26 of the profiled beam 1 of a supporting structure with a counter plate 24 and plate 22 fastened to it, the latter two being in the mutual angular position shown in FIG. 10. The profiled beam 1 and the running rail 3 are parallel to one another and run normally to an imaginary connecting line between the through bores 56 in the counterplate 24 or the fastening means 25 assigned to them. In this angular position, the running rail 3 can be fastened to a profiled beam 1 with the greatest possible width of the horizontal flange 26 are hung, this horizontal flange width by the distance between the through bores 56 in the counter plate 24 is limited.

However, the running rail 3 can also be suspended in a very simple manner from a profile carrier 1, the horizontal flange 26 of which has a smaller width than the profile carrier shown in FIG. 12. This is shown in Fig. 13. The counter plate 24 is rotated in a clockwise direction with respect to the profile support 1, so that the imaginary connecting line between the fastening means 25 and the longitudinal axis of the profile support 1 extend at an angle to one another. The size of the included angle is inversely related to the width of the horizontal flange 26. In the present exemplary embodiment, the plate 22 is rotated together with the counter plate 24 relative to the profiled beam 1, so that the running rail also extends obliquely to the profiled beam at the same angle. It is easy to see that it is only necessary to turn the plate 22 counterclockwise in the manner described above in order to return the running rail 3 to its old angular position, i.e. to bring parallel to the profile beam 1.

The holder according to the invention can of course also be used for turnout suspensions, sliding transfers and fixing devices of monorail overhead conveyors and also for profile supports in general. If five or more cap screws 23 are used to connect the plate 22 and the counterplate 24, two or more of these screws 23 can also be connected to one another in order to accelerate the insertion or removal.
