Description

Fastening unit for fastening a component, in particular a pipe or similar object

The invention relates to a fastening unit for fastening a component, in particular a pipe or similar object, to a hollow profile beam with a substantially C-shaped cross-section with two opposite legs of a long side, which span a mounting opening, in particular a mounting slot, between them, consisting of an elongated support plate provided with a threaded hole, the large diagonal or longitudinal axis of which is larger and the small diagonal or transverse axis of which is smaller than the width of the mounting opening of the hollow profile beam, a threaded bolt being guided through the support plate and the support plate being able to be inserted into the mounting opening and rotated inside the hollow profile beam in such a way that the support plate is able to grip behind the legs of the hollow profile beam on the inside, as well as with a pressure disk having a through hole for counter-holding, which rests on the legs from the outside and through which the threaded bolt is guided, on which a lock nut is screwed in the direction of the pressure disk for holding the support plate and pressure disk on the hollow profile beam. is screwed, whereby the support plate and pressure disk can be clamped and moved relative to one another by means of an elastic element when they are rotated relative to one another, according to the preamble of claim 1.

DE 38 23 000 C2 has disclosed a fastening unit for fixing a structural element, in particular a pipe, to a hollow profile beam provided with at least one slot on one side surface, by means of a tubular component provided with an internal thread, which has a collar at one end and into whose internal thread a threaded bolt can be screwed, which carries the structural element to be fixed at the other end. When fixing the fastening element in a slot of the hollow profile beam, after inserting the tab together with the tubular nut and the nut screwed onto the external thread of the tubular component, the nut is tightened after the fastening unit has been aligned with a specific point on the hollow profile beam, whereby it is fixed.

is rotated in such a way that the support part engages behind the holding projections provided on the inside on opposite long sides of the rail and is provided with a rectangular counterholder which acts on the edges of the long sides of the rail that delimit the assembly opening on the outside and which is rotatably connected to the support part. Between the counterholder and the support part there is a restoring element that can be tensioned by rotating these two parts relative to each other, namely a spring that can be subjected to tension and torsion. A rotation limiting stop for the support part that is effective in the rotation preload direction is provided on the hollow profile rail or on the counterholder, so that the support part in the rotation preload position engages over the holding projections in a rotationally relaxed position. The counterholder has two opposite side walls that engage over the hollow profile rail on each side when the counterholder is rotated by 90 degrees. At the edges that run at 90 degrees to the side walls, the counterholder also has two opposing walls for spacer support, each of which has an inclined plane and whose length is shorter than the width of the assembly opening into which the walls come to lie after the counterholder is rotated.

EP 0 553 765 A1 discloses a similar anchoring unit for fastening pipes to a hollow profile rail with a mounting opening and a support part as well as a counterholder in a number of variations, in which the support part and counterholder are connected to one another by means of a spring that can be subjected to tension and torsion.

DE 44 47 456 A1 has disclosed a mounting rail with a similar rotatable anchoring unit for fastening pipes to DE 196 17 750 Cl, in which the support part and the counterholder are connected to one another in a substantially rotationally fixed manner by means of a spacer that can be compressed in the direction of insertion, which consists of an elastomer or foam material and can have a flexible shape.

Furthermore, a hammer head screw for ceiling fastening with a clamping element pushed onto a screw shaft has already been proposed, which has either a rubber-elastic tension spring element in the form of an elastic ring or band, which engages a screw head and the clamping element and which pulls the clamping element towards the screw head, or a compression spring element, which presses the clamping element towards the screw head.

However, the variety of known anchoring units for fastening pipes or similar objects still have disadvantages, which hinder either inexpensive production as a mass product or quick and captive assembly on site.

The invention is therefore based on the object of creating a fastening unit for fastening a component, in particular a pipe or similar object, according to the type mentioned at the beginning, which can be inexpensively manufactured and pre-assembled as a mass-produced article and whose individual parts simplify and accelerate assembly on site in a non-losable and unmistakable manner.

The solution to the problem according to the invention is that the elastic element between the support plate and the pressure disk is either a molded part or a disk made of a rubber or spring-elastic material, which is coated on its top and bottom with an adhesive, so that the support plate and pressure disk are connected quasi-rigidly by means of the self-adhesive disk or the molded part, the outer diameter of the disk or the molded part being slightly larger than the assembly opening of the hollow profile carrier, or that the elastic element is an elastic band or rubber ring or a compression spring.

The parts of the support plate, the pressure disc and the elastic disc or spring thus form a fastening unit that can be inserted and fixed into the assembly opening of the hollow profile beam independently of the threaded bolt and the lock nut; only then is the threaded bolt screwed in and the lock nut screwed onto it tightened. The larger outer diameter of the rubber-elastic disc advantageously exerts a compressive force on the hollow profile beam, which effectively prevents the fastening unit from moving unintentionally, even when the hollow profile beam is mounted at an angle or vertically.

Further advantageous embodiments of the invention are characterized in the remaining subclaims.

While the support plate is parallelogram-shaped in one embodiment and is wider in the diagonal direction than the clear width of the hollow profile beam and thus, after turning by about 90 degrees, strikes the inner wall of the hollow profile beam, an advantageous further embodiment of the fastening

- 12 -

unit has a support plate with rounded ends, which allows for unhindered rotation after insertion into the hollow profile beam. The pressure disc is provided with raised edges, which rest on the webs of the hollow profile beam from the outside when the fastening unit is inserted, whereby when pressed into the mounting slot the rubber-elastic disc is stretched in height and thus a tensile stress is created, which, after the fastening unit has been rotated by 90 degrees, allows the raised edges of the pressure disc to snap into the mounting opening of the hollow profile beam, such that in this position the support plate is perpendicular to the longitudinal axis of the hollow profile beam and the fastening unit can then be firmly anchored. The advantage of this design of the fastening unit is that it is easier to assemble - the fitter feels it click into place when turning -, the further rotation for the purpose of adjusting the height of the threaded bolt without being loaded by a secondary fastening element, as well as its torsion-proof anchoring in the hollow profile support after tightening the lock nut provided for this purpose on the external thread.

A further improvement in terms of vibration-resistant anchoring in the hollow profile beam is achieved by providing the support plate with an approximately square recess that engages in the assembly opening of the hollow profile beam from the inside and the square or round pressure disc is provided with raised edges that also fit into the assembly opening and that grip over the support plate after it has been firmly anchored. The pressure disc can be square in order to transfer greater forces, while the round pressure disc can be manufactured more economically.

For higher loads, the square pressure disc is provided with continuous raised edges on both of its free sides, which extend over the outside of the long side of the hollow profile beam. The advantage of this arrangement is the stiffening of the hollow profile beam in the area where the fastening unit is anchored, while preventing the forces to be transmitted by secondary fastening elements from widening the slot.

If the external thread of the sleeve and the nut are dispensed with for economic reasons, the rubber-elastic disc exerts pressure on the shaft of the sleeve if its inner diameter is slightly smaller than the outer diameter of the shaft of the sleeve; the sleeve, which is now smooth on the outside, does not move automatically, and instead of the pressure exerted on the outer

k μ m Λ �iacgr;

- 13 -

a smooth pressure sleeve is pushed onto the shaft of the sleeve using a nut screwed on with a thread and the inner surface of the pressure sleeve is coated with a permanently elastic putty, whereby the latter is fixed to the sleeve and the connection is sufficient to rotate the sleeve after the fastening unit has been inserted into the hollow profile support in order to adjust the height of the secondary fastening elements (pipe). The longitudinal displacement of the fastening unit in the direction of the longitudinal axis of the hollow profile support is not impaired by the rubber-elastic disk after it has been inserted into the hollow profile support. The length of the pressure sleeve protrudes slightly over the lower edge of the sleeve, so that after the fastening unit has been inserted into the hollow profile support, the fastening unit and the threaded bolt are firmly anchored in the hollow profile support by tightening the lock nut.

In further development of the fastening unit, the outer contour of the sleeve and also the pressure sleeve can have a hexagonal shape inside and out with the advantage that the sleeve can be turned for height adjustment using a wrench placed on the pressure sleeve.

The pressure sleeve can also be designed in the form of a longitudinally slotted clamping sleeve, e.g. made of spring steel with a round or hexagonal cross-section, which does not require a coating with a permanently elastic putty, where the required clamping force is achieved by the elastic expansion that occurs when the pressure sleeve is pushed onto the sleeve.

A simpler version of the fastening unit provides a rectangular or round pin instead of the collar on the sleeve or the fixed connection between the sleeve and the support plate as a replacement for the support plate, which is pushed through a rectangular or round opening in the upper part of the sleeve, held there by a permanently elastic putty or glued or welded to the sleeve and whose length is slightly smaller than the clear width of the hollow profile support. The advantage of this design is more economical and is particularly suitable for smaller loads, such as those that occur in electrical installations.

In a further design of the fastening unit, the two edges of the square or round pressure disc are provided with two lateral recesses and a slightly wider upper recess, into which an endless rubber-elastic band is inserted, which is stretched over the sleeve with the support plate inserted and thereby

- 14 -

adhesive rubber-elastic disk. The advantage of this arrangement is of an assembly-technical nature. By means of the tension of the rubber-elastic band, the parts of the fastening unit are pressed together so tightly that even with heavier parts, the fastening unit is securely fixed at the desired location in the hollow profile support. The pressure disk is also provided with recesses on the sides that are adjacent to the sides with raised edges and which are gripped during assembly, and the support plate with sleeve is pressed upwards so far that, with a simultaneous rotational movement, the support plate slides with its underside onto the webs of the hollow profile support and, after a 90-degree rotation, the lower part of the support plate snaps into the slot from the inside, whereby the pressure disk is simultaneously taken along by the rubber-elastic band and the raised edges of the pressure disk snap into the slot from the outside and grip over the support plate, whereby the fastening unit is held against twisting and displacement by the rubber-elastic band. Nevertheless, the rotatability of the sleeve and the displaceability of the fastening unit in the longitudinal direction of the hollow profile beam are retained.

Particularly useful compared to the prior art DE 38 23 000 C2 are further developed embodiments of fastening units according to the invention, which are characterized in that they:

a) assembled faster,

b) secured against torsion in the hollow profile beam,

c) easier to adjust - even under load,

d) anchored in the hollow profile beam in a vibration-resistant manner,

e) more easily adapted to different load requirements, and

f) can be pre-assembled at the production site.

Further advantages of the fastening unit according to the invention include: quick insertion into the hollow profile support, quick locking and quick release and adjustment, assembly independent of secondary fastening elements (pipe) and statically dimensionable. Furthermore, a defined force transmission is possible, e.g. by using torque wrenches, and there is longitudinal adjustment and thus adjustability of the secondary fastening elements. Finally, a continuous alignment of the secondary fastening elements, such as pipes, cables, cable ducts, ceiling and floor structures, shelves, rails, angles and the like, in any position, hanging horizontally or lying, vertically or at an angle is possible.

To further simplify the assembly of the fastening unit, a conical compression spring can be arranged between the pressure disk and the nut screwed onto the external thread of the sleeve. After the nut has been tightened and the fastening unit has been inserted into the hollow profile support, this spring exerts such pressure on the latter that uncontrolled displacement of the fastening unit in the hollow profile support is no longer possible. The insertion of the fastening unit itself is also considerably accelerated and simplified, even if the disk is not inserted. Nevertheless, the fastening unit can be moved in a controlled manner in the hollow profile support and the sleeve can be rotated for height adjustment if the tension of the conical compression spring is reduced by pressure applied from the outside. When the nut is fully tightened onto the external thread of the sleeve, the conical compression spring is pressed flat and acts like a washer that secures the fastening unit.

The following improvements also serve to simplify the assembly of the fastening unit: a conical compression spring is arranged under the pressure disk on the smooth outer surface of the sleeve, the inner diameter of which is slightly smaller than the outer diameter of the sleeve, so that it is pushed onto the outer surface with pre-tension and, after the fastening unit has been inserted into the hollow profile support, exerts such pressure on the latter that uncontrolled displacement of the fastening unit in the hollow profile support is no longer possible. This makes the insertion of the fastening unit considerably faster and easier, even if the disk is not used or if an endless rubber-elastic band or a ring made of permanently elastic putty is used instead. Nevertheless, the fastening unit can be moved in a controlled manner in the hollow profile support and the sleeve can be rotated to adjust the height if the tension of the conical compression spring is reduced by pressure applied to the sleeve from the outside. When the nut is tightened on the threaded bolt, the conical compression spring is pressed flat with the help of the pressure sleeve and acts like a washer that secures the fastening unit.

To further improve the assembly of the fastening unit, the two raised edges of the square or round pressure disc are each equipped with one or two diagonally opposite additional elevations, which serve to anchor the support plate after it has been clamped against the pressure disc using the endless rubber-elastic band. One variant of the pressure disc has two raised edges on each of its

- 16 -

Provide elevations with such a clear distance that the support plate or threaded plate can engage with its narrow sides.

For this purpose, the fastening unit is pre-assembled as described above. The support plate is then raised so far that it can be rotated over the additional elevations while simultaneously tensioning the elastic rubber band until it snaps into place behind or between the latter. The fastening unit is delivered in this pre-assembled state and inserted into the hollow profile support by the fitter. For final assembly, the support plate is now pushed into the hollow profile support so far that it can slide back over the additional elevations, pulled by the elastic rubber band, and automatically jumps into the final assembly position and anchors itself there.

The same result is achieved if a threaded plate made up of both parts is used instead of the sleeve and the support plate. Depending on requirements, this threaded plate can be rotatable or rounded with a stop on the front sides or can be parallelogram-shaped or rectangular. The length of the rounded threaded plate and the diagonal of the rectangular threaded plate will be slightly smaller than the clear width of the hollow profile support, while the large diagonal of the parallelogram-shaped threaded plate will be slightly larger and the small diagonal slightly smaller than the clear width of the hollow profile support.

The thickness or height of the thread of the threaded plate is determined by the forces to be transmitted. For higher requirements, it may be useful to retain part of the round shaft of the sleeve on the threaded plate, the height of which is determined on the one hand by the material thickness of the hollow profile support, pressure disc and the wire diameter of the conical compression spring, and on the other hand part of the clear space within the hollow profile support can also be used for this purpose. The height of the said shaft is selected in such a way that the fastening unit can be inserted unhindered into the hollow profile support and the nut can be tightened unhindered for anchoring.

Instead of the endless rubber-elastic band, a flat rectangular rubber-elastic shaped piece can also be used, in which an opening is provided on each of its two end faces, which can have the form of a hole, a slot or a similar opening and

- 17 -

which is hung under pre-tension in the recesses provided in the raised edges of the pressure disc. After hanging, the rubber-elastic molded part lies completely or partially over the central hole in the sleeve or threaded plate. If the threaded bolt is now screwed into the fastening unit, the fitter will feel a clear resistance to screwing in as soon as the threaded bolt has to push the rubber-elastic molded part to the side. This advantageously ensures that the threaded bolt is completely screwed into the thread of the sleeve or threaded plate and the height adjustment can be carried out without risk.

For certain hollow profile beams with a smaller slot width, it may be appropriate to arrange the central hole in the support plate or the central threaded hole in the threaded plate off-center and to insert the fastening unit tilted more or less to the side into the slot of the hollow profile beam, with the advantage that the width of the support plate or the threaded plate can be slightly larger than the slot width, thus improving the overall force transmission.

An advantageous further development of the invention is that instead of the disc made of a rubber-elastic material and the rubber-elastic band, a specially shaped steel spring is used and instead of the pressure disc, a specially shaped pressure disc is used. The steel spring is shaped in such a way that it sits firmly on the support plate on the one hand and firmly on the specially shaped pressure plate on the other hand and simultaneously presses both parts together with pre-tension and both parts can be turned against each other with pre-tension during pre-assembly so that they can lock into each other behind the raised edges of the pressure disc and anchor themselves.

Instead of the specially shaped steel spring, one or two rubber-elastic bands or the rubber-elastic molded piece described can be used together with the specially shaped pressure plate in an economically advantageous manner for certain areas of application.

For higher loads, the specially shaped steel spring can be assembled with the conical compression spring to form a combination spring unit, which together with the specially shaped pressure plate can be used for all

The fastening units described under A. and B. replace the rubber-elastic disc and the pressure plate used there.

The fastening units described above can be combined with one another with the advantage that, depending on requirements, the various elements can be assembled into different fastening units during production and pre-tensioned if necessary, and are thus available for simple, safe and quick installation in a hollow profile beam during assembly on site.

In Figures 1-17, the reference number 1 designates the support plate located in the interior of the hollow profile support 6 and the reference number 2 designates the tubular sleeve provided with a collar 21, an internal thread 23 and an external thread or with a smooth outer surface 22 or optionally with a hexagonal outer surface 24 - the said external thread and the associated nut are not shown. The sleeve 2 is inserted into a hole 11 in the support plate 1, whereby the collar 21 attached to the sleeve 2 rests on the support plate 1, which rests on the lower inner surface on webs 62 and 63 of a hollow profile support 6. The width of the collar 21 and that of the support plate 1 are each smaller than the width of the assembly opening in the form of a slot 61 in the hollow profile support 6, so that both parts can be inserted into the hollow profile support 6 from the outside during assembly. In one embodiment, the support plate 1 is designed as a parallelogram, the longer diagonal of which is larger than the clear width of the hollow profile beam, so that the support plate 1, when screwed into the hollow profile beam, comes to a stop on the vertical inner surfaces 64 and 65 of the hollow profile beam 6 and is thus fixed in a rotationally secure manner, but can of course be turned back.

A disc 3 or a molded part 3, which consists of a rubber-elastic or flexible material with restoring force, preferably foam rubber or elastomer, is coated with adhesive on both its upper and lower surfaces 31, 32 and is thus attached to the lower surface of the support plate 1 as

- 21 -

The inner diameter of the disk 3 is slightly smaller than the outer diameter of the shaft 22 of the sleeve 2, the outer diameter is slightly larger than the width of the slot 61 of the hollow profile support 6, so that the rubber-elastic disk 3 both presses on the shaft 22 of the sleeve 2 and clamps itself in the slot 61 of the hollow profile support 6 when inserted into the latter.

A pressure disk 4 is pushed over the shaft 22 of the sleeve 2 and pressed against the lower adhesive-coated surface 32 of the rubber-elastic disk 3. A pressure sleeve 5 is pushed over the shaft 22 of the sleeve 2, the inner surface 51 of which is coated with a thin layer of a permanently elastic putty, and pressed against the pressure disk 4.

Parts 1 to 5 are pre-assembled by the manufacturer in a captive manner and are provided as a fastening unit so that they can be inserted into the hollow profile support 6 and held there independently of a threaded bolt 7.

The locking washer 8 and the lock nut 9 on the threaded bolt 7 serve to firmly anchor the fastening unit in the hollow profile support 6 and also to fasten the threaded bolt 7 in the sleeve 2. Secondary elements to be fastened in a suitable manner, such as a pipe, then grip the threaded bolt 7.

Figure 2 shows a fastening unit according to Figure 1 in the assembled and anchored state in the hollow profile support 6 with screwed-in threaded bolt 7, locking washer 8 and lock nut 9.

Figure 3 shows two optionally usable sections through the shaft of the sleeve 2, with 22 indicating the smooth round surface and 24 the smooth hexagonal surface of the shaft.

Figure 4 shows a support plate 1 rounded at the end faces 12, 13, the length of which is smaller than the clear width of the hollow profile beam 6, so that the support plate can be rotated inside the hollow profile beam.

Figure 5 shows a modified support plate 1 with the rounded portions 12 and 13 on the front sides according to Figure 4, whereby the support plate forms a unit with the sleeve 2 and an unhindered rotation of the fastening unit after the

- 22 -

Insertion into the hollow profile support 6 for height adjustment without loading by a secondary fastening element (not shown) is permitted. In addition, alternatively, a slot 201 can be arranged on the outside in the direction of the longitudinal axis of the shaft 22 of the sleeve 2, into which a pin 472 of the pressure disk 4 engages according to Figure 17, or a flattening can be arranged, which ensure that the sleeve 2 is carried along when the pressure disk 4 is rotated for height adjustment, whereby the sleeve 2 can also be optimally dimensioned in terms of strength. This slot 201 or flattening can also be provided as an alternative in the sleeve 2 according to Figure 1 or Figure 8.

Figure 6 shows a modified round pressure disk 4 with raised edges 41, 42, 43 and 44, the distance between the raised edges 41 and 42 or between 43 and 44 being smaller than the width of the slot 61 in the hollow profile support 6, so that these raised edges can snap into the slot 61 during assembly and thus secure the fastening element against twisting. The pressure disk 4 can also be square.

Figure 7 shows four sections through the pressure sleeve 5 designed in four alternatives, whereby the inner diameter 511 of the round pressure sleeve 5 is slightly larger than the outer diameter of the round shaft 22 of the sleeve 2 and is coated on the inner surface 51 with a thin layer of a permanently elastic putty and in the hexagonal version 52 the inner width 531 of the hexagon is slightly larger than the wrench width of the hexagonal shaft 24 of the sleeve 2 and is also coated on the inner surface 53 with a thin layer of a permanently elastic putty.

Two further sections show the round pressure sleeve 54, which is alternatively slotted with a longitudinal slot 512 and is made of an elastic material, e.g. spring steel, whereby the inner diameter 511 of the round pressure sleeve 54 is slightly smaller than the outer diameter of the round shaft 22 of the sleeve 2 and in the hexagonal version with longitudinal slot 532 the inner width 531 of the hexagonal pressure sleeve 55 is slightly smaller than the wrench width of the hexagonal shaft 24 of the sleeve 2.

Figure 9 shows a modified support plate 1 with depressions 14 and 15, here the distance between the depressions 14 and 15 is smaller than the width of the slot 61 in the hollow profile support 6, so that these depressions can snap into the slot 61 during assembly and thus additionally

- 23 -

secure against twisting. To facilitate assembly, the corners 141, 142 and 151,152 of the recesses are rounded.

Figure 10 shows another modified, square pressure disk 4 with raised edges 45 and 46 from two opposite side edges, the length of the raised edges being smaller than the width of the slot 61 in the hollow profile support 6, the height of the raised edges being greater than the material thickness of the webs 62, 63 of the hollow profile support 6, so that these raised edges can snap into the slot 61 during assembly and grip over the recesses 14, 15 of the support plate 1, thus additionally securing the fastening element against twisting. The pressure disk 4 can also be round.

Figure 11 shows a fastening unit with parts 1-5 in the assembled state with hollow profile carrier 6, support plate 1 according to Figure 9 and pressure disk 4 according to Figure 10 as well as rubber-elastic disk 3, and pressure sleeve 5 in the position of insertion into the hollow profile carrier 6 before turning the support plate 1.

Figure 12 shows a square pressure disk 4 provided with additional lateral raised edges 47 and 48 in section and in plan view, the said raised edges of which, when inserted into the hollow profile carrier 6, extend over its vertical side walls 64 and 65 from the outside and thus increase the mechanical rigidity of the hollow profile carrier 6 at the location of the fastening unit.

Figure 13 shows a further modified square pressure disk 4 with raised edges 411 and 412, each of which is suitable for receiving an endless rubber-elastic band 161 with two lateral recesses 451 and 452 and a slightly wider upper recess 453, and said pressure disk is provided with two additional recesses 454 and 455 to facilitate assembly, in section, in plan view and in side view. The pressure disk 4 can also be round.

Figure 14 shows an assembled fastening unit in section and in plan view, consisting of sleeve 2, support plate 1 according to Figure 9, pressure sleeve 5 and pressure disk 4 according to Figure 13 with two lateral recesses 451, 452 and a slightly wider upper recess 453, into which an endless rubber-elastic band 161 is inserted, which is connected via the sleeve 2 with

- 24 -

inserted support plate 1 and replaces the double-sided adhesive rubber-elastic disk 3. In this design, the support plate 1 can be coated on the inner surface of its bore 11 with a thin layer of a permanently elastic putty. The parts 1, 2, 4, 161 and 5 in turn form an independently mountable fastening unit. The advantage of this arrangement is in terms of assembly technology, particularly for heavier fastening elements that are used for higher loads.

When inserting this fastening unit into the slot 61 in the hollow profile support 6, the fitter uses two fingers to grasp the support plate 1, which is so much narrower than the clear width of the slot 61 that the rubber-elastic band 161 still has space, pushes it upwards so far that its underside extends slightly over the upper edge of the two webs 62 and 63 of the hollow profile support 6 and allows the support plate 1 to slide onto them by means of a slight turning movement, while simultaneously taking the pressure disk 4 with it. After turning by 90 degrees, the depressions 14, 15 of the support plate 1 and the raised edges 411, 412 of the pressure disk 4 snap into the slot 61 by means of the tension of the rubber-elastic band 161 and the contact surfaces of the support plate 1 and the pressure disk 4 are thus placed on the webs of the hollow profile carrier so that they cannot slip out of the mounting location on their own. In a similar way, the fastening unit can be removed from the mounting location by pulling the pressure disk 4 with the rubber-elastic band 161 downwards and then turning it so that its raised edges can slide onto the underside of the hollow profile carrier; the support plate 1 is thereby taken along by the rubber-elastic band 161 and, after turning 90 degrees, jumps out of the slot 61. The rotatability of the sleeve 2 for the purpose of adjusting a secondary fastening element is not impaired in this embodiment of the invention either, because the rounded areas 141, 142, 151 and 152 on the corners of the depressions 14 and 15 of the support plate 1 and on the raised edges of the pressure disk 4 enable it to slide onto the webs 62 and 63 with only slight resistance. The firm anchoring of the fastening unit of this embodiment is carried out in the same way as in the previously described embodiments.

Figure 15 shows a sleeve 2, which is combined with the support plate 1 to form a flat component 171 for a fastening unit, in section and in plan view, which is particularly suitable for smaller loads. This component 171 can optionally be fitted with the rubber-elastic disk 3 and the

- 25 -

Pressure disk 4 according to Figure 1 or pressure disk 4 according to Figure 6 or Figure 10 or Figure 12 or also instead of the rubber-elastic disk 3 with the rubber-elastic band 161 and the pressure disk 4 according to Figure 13 can be combined to form a fastening unit.

Figure 16 shows an example of a fastening unit in the assembled state with hollow profile support 6, threaded bolt 7 and lock nut 9, in which the fastening element consists of the flat component 171 according to Figure 15, the rubber-elastic disk 3 according to Figure 1 and the pressure disk 4 according to Figure 10, which can be rotated in the hollow profile support for adjustment without load as long as the nut 9 is not tightened against the pressure disk 4. When turning the fastening unit, the fitter can see and feel, as previously described, when it is in the locking position. After tightening the nut 9 against the pressure disk 4, the fastening element is pulled into the slot 61 and is anchored there so that it cannot rotate or move.

Figure 17 shows a square pressure disk 4, which can also be round, as described in Figure 10, with a hexagon 471 recessed or welded onto its underside, which serves to make it easier to rotate the fastening unit during adjustment and whose clear width is slightly larger than the nominal diameter of the shaft 22 of the sleeve 2, so that it fits into the hexagon, and whose height is slightly larger than the length of the shaft of the sleeve 2, e.g. according to Figure 5. In addition, a pin 472 or a flattening can be arranged in the central bore of the pressure disk 4, which engages in a corresponding slot 201 arranged outside in the direction of the longitudinal axis of the shaft 22 of the sleeve 2, as shown in Figure 5, for example, and ensures that the sleeve 2 can be rotated and thus the fastening unit can be adjusted even under load. In the case of using the hexagon 24 for the shaft of the sleeve 2, the hexagon of the pressure plate 4 is designed so that it fits onto said hexagon 24.

Figures 21 and 22 show a support plate 1 located in the interior of the hollow profile support 6 and a tubular sleeve 2 provided with a collar 21, an internal thread 23 and a smooth outer surface 22 or optionally with a hexagonal outer surface or an external thread - the said external thread and the associated nut are not shown in the drawings. The sleeve 2 is inserted into a bore 11 of the support plate 1, whereby the collar 21 attached to the component 2 rests on the

- 26 -

Support plate 1 rests on the lower inner surface of the webs 62 and 63 of the hollow profile support 6. The width of the collar 21 and that of the support plate 1 are each smaller than the width of the slot 61 in the hollow profile support 6, so that both parts can be inserted into the hollow profile support 6 from the outside during assembly. The support plate 1 is designed in the shape of a parallelogram and the diagonal of the parallelogram is larger than the clear width of the hollow profile support, so that the support plate 1 comes to a stop on the vertical sides 64 and 65 of the hollow profile support 6 when screwed into the hollow profile support and is thus fixed.

A disk 3 made of a rubber-elastic material, preferably foam rubber or an elastomer, is coated with adhesive on both its upper surface 31 and its lower surface 32 and is attached to the lower surface of the support plate 1 as an assembly aid; the inner diameter of the disk 3 is slightly smaller than the outer diameter of the shaft 22 of the sleeve 2, while the outer diameter is slightly larger than the width of the slot 61 of the hollow profile support 6, so that the rubber-elastic disk 3 both presses on the shaft 22 of the sleeve 2 and clamps itself in the slot 61 when inserted into the hollow profile support 6. A pressure disk 4 is pushed over the smooth round shaft 22 of the sleeve 2 and pressed against the lower surface 32 of the rubber-elastic disk 3 coated with adhesive.

A conical compression spring 10, whose innermost diameter d is slightly smaller than the outer diameter of the sleeve 2, is pushed onto the smooth shaft 22 with pre-tension and, after the fastening unit has been inserted into the hollow profile support 6 by means of component 2, support plate 1 and pressure disk 4, exerts such a pressure on the webs 62 and 63 that an uncontrolled displacement of the fastening unit in the hollow profile support 6 is no longer possible.

A pressure sleeve 5 is pushed over the shaft 22 of the sleeve 2 and presses against the conical compression spring 10 by means of a threaded bolt 7, washer 8 and nut 9.

Parts 1 to 4 and 10 are pre-assembled by the manufacturer in a captive manner and provided as a fastening unit so that it can be inserted into the hollow profile support 6 independently of the pressure sleeve 5, threaded bolt 7 and secondary elements.

- 27 -

The pressure sleeve 5, locking washer 8 and the nut 9 on the threaded bolt 7 serve to firmly anchor the fastening unit in the hollow profile support 6 and also to fasten the threaded bolt 7 in the component 2.

Figure 22 shows a fastening unit in the assembled and not yet firmly anchored state in the hollow profile support 6 with screwed-in threaded bolt 7, locking washer 8 and nut 9.

Figure 23 shows a modified support plate 101, rounded on the end faces 12, 13, whose length is smaller than the clear width of the hollow profile support 6, with the depressions 14 and 15, the distance between the depressions 14 and 15 being smaller than the width of the slot 61 in the hollow profile support 6, so that these depressions can snap into the slot 61 during assembly and thus additionally secure the fastening unit against twisting. To make assembly easier, the corners 141, 142 and 151, 152 of the depressions are rounded.

Figure 24 shows a fastening unit with the parts 101,2,3,401 and 10 in the assembled state with hollow profile support 6, support plate 101 according to Figure 23 and pressure disk 401 with the upstands 45 and 46 as well as rubber-elastic disk 3 and conical compression spring 10 in the position of insertion into the hollow profile support 6, wherein the upstands 45 and 46 are placed on the webs 62 and 63 of the latter.

Figure 25 a, b, c shows an example of a fastening unit in the assembled state with hollow profile support 6, threaded bolt 7 and nut 9, in which the fastening unit consists of the flat component 203, the rubber-elastic disk 3, the pressure disk 401 and conical compression spring 10, which can be rotated in the hollow profile support for adjustment without load as long as the nut 9 is only slightly tightened against the conical compression spring 10. When turning the fastening unit, the fitter can see and feel, as previously described, when it is in the locking position. When the nut 9 is fully tightened against the conical compression spring 10, the fastening unit is pulled into the slot 61 and is anchored there so that it cannot be rotated or moved.

Figure 26 a, b, c shows a further modified square pressure disk 403 with the raised edges 411 and 412, each of which has two lateral recesses 451 and 452 and a slightly wider upper recess.

• ft · ·

- 28 -

recess 453 is suitable for receiving an endless rubber-elastic band 1010 and said disk is provided with two additional recesses 454 and 455 and with additional elevations 456,457 to facilitate assembly in section, in plan view and in side view. The raised edge 411 is provided with an additional elevation 456 and the raised edge 412 with an additional elevation 457. The pressure disk 403 can also be round. Deviating from the illustration in Figure 6, each of the two raised edges 411,412 can each have two lateral elevations 456,457, the clear distance between which corresponds at least to the width of the support plate 1,101,203 or the threaded plate 204. Also deviating from the representation in Figure 6, the recesses 451,452 can be of different depths, higher or wider, mirror-image or L-shaped depending on the task.

Figure 27 shows an assembled fastening unit in section and in plan view, consisting of component 203 and pressure disk 403 according to Figure 26 with two lateral recesses 451, 452 and a slightly wider upper recess 453, into which an endless rubber-elastic band 1010 is inserted and stretched over component 203, in this way pressing the two parts 203 and 403 against each other and replacing the rubber-elastic disk 3 adhesive on both sides. The raised edge 411 of pressure disk 403 is provided with an additional elevation 456 and the raised edge 412 with an additional elevation 457, behind which component 203 can be clamped by turning it to the left in the plan view shown by approx. 120-140° while pre-tensioning the rubber-elastic band 1010. Parts 203,403 and 1010, pre-tensioned during production if required, form an independently mountable fastening unit.

Depending on the requirements, this component 203 can be designed to be rotatable in the hollow profile support 6 or with a stop, rounded on the front sides as shown, or parallelogram-shaped or rectangular. The length of the rounded component 203 and the diagonal of the rectangular component will be slightly smaller than the clear width of the hollow profile support 6, while the large diagonal of the parallelogram-shaped threaded plate 204 is selected to be slightly larger and the small diagonal slightly smaller than the clear width of the hollow profile support. If, for example, a rectangular threaded plate (not shown) is used instead of the rounded component 203, then a pressure disk 403 with two additional elevations 456,457 is used on the raised edges 411,412, between which the rectangular threaded plate can snap into place during pre-tensioning.

- 29 -

Instead of the endless rubber-elastic band 1010, a flat rectangular rubber-elastic shaped piece (not shown) can also be used, in which an opening in the form of a hole, a slot or a similar opening is provided on both of its end faces, and which is suspended under pre-tension in the recesses 451, 452 provided for this purpose in the upstands 411, 412 of the pressure disk 403.

The advantage of these arrangements is of an assembly-technical nature - the fitter inserts the fastening unit into the slot 61 of the hollow profile support 6 and at the same time presses the component 203 into the hollow profile support with a suitable pin until the rubber-elastic band or rubber-elastic molded piece presses the component 203 into its component 203 as a result of its pre-tensioning and the raised edges 411,412 of the pressure disk 403 into the slot 61 by means of the pre-tensioning of the rubber-elastic band 1010 or the rubber-elastic molded piece and the contact surfaces of the sleeve 203 and the pressure disk 403 are pressed onto the webs 62 and 63 of the hollow profile support 6 in such a way that they cannot slip out of the assembly point by themselves. In a similar way, the fastening unit can be removed from the mounting location by pulling the pressure disk 403 downwards and then rotating it so that its raised edges can slide onto the underside of the hollow profile support, whereby the component 203 is carried along by the rubber-elastic band 1010 or rubber-elastic molded piece and, after rotating by 90 degrees, jumps out of the slot 61.

Figures 31 and 32 show additional sleeves 2 in the assembled state, which have a knurling 24 on their surface 22, with the help of which the fitter can more easily turn the sleeve 2 to adjust the height of the threaded rod 7. Figure 31 shows a sleeve 2 on which the parts 1, 3, 4 are arranged and which is equipped with an additional bead 25, over which the sleeve 5 is pushed and then provided with a flange 51 at two opposite points or on the entire circumference, which serves to fasten the sleeve 5 in such a way that it can no longer be pulled off the sleeve 2 and nevertheless reliably fulfills its function of pressing against the pressure disk 4. Another variant is shown in Figure 32. Here, the sleeve 2 is equipped with an additional semicircular or angular recess 27, into which a rubber-elastic ring 28 is inserted, over which the sleeve 5 is pushed in a press fit and thus sits firmly but displaceably on the surface 22.

Figure 33 shows another pressure disk 404 with recesses or undercuts 4512, 452 provided with raised edges 411, 412, which are additionally equipped with an elongated hole 458, 459 or a round hole. The rubber-elastic band 161, 1010 is drawn into this hole, as shown in Figure 34, advantageously from the inside to the outside. It is obvious to use a pressure disk according to the pressure disk 404 instead of the pressure disk 4, 403 in the fastening unit according to Figures 14, 18 and 27 and to proceed as described for Figure 34.

Figure 34 shows a pre-assembled disc 33 that is only adhesive on one side with an adhesive side 34 of a fastening unit with which the disc 33 is glued either to the support plate 171 (1,191,203) or to the pressure disc 4, 404 wherein the parts 1,4 in Figure 14 or the parts 171, 404, 191, 404 or 203, 404 are held together by means of the endless rubber-elastic band 161. This combination serves to facilitate assembly. Figure 34 shows this combination in the assembly position, in which the pressure P causes the support plate 171,191,203 to be lifted up with an auxiliary tool so far that it can slide onto the webs 62,63 of the hollow profile support 6 and the disc 33 serves as additional support in the hollow profile support. The rubber-elastic band 161 is, for example, guided through the elongated holes 458, 459 of Figure 33 of the pressure disk 404 from the inside to the outside and hung in the recesses or undercuts 451, 452 of the upstands 411, 412 from the outside to the inside, which has the advantage that the fastening unit can be more easily inserted into the hollow profile support.

The design of another pre-assembled fastening unit according to Figure 35 is the same in its effect as that described above, with one or two rubber-elastic bands 161 being glued on the one hand into an adhesive joint 36 between the disk 35 and the flat support plate 171, 191, 203 and on the other hand into the adhesive joint 34 between the disk 33 and the pressure plate 4 according to Figure 6. Figure 35 shows this combination in the assembly position, in which the flat support plate 171 (191, 203) is lifted up by the pressure P.

Figure 36 shows how, instead of the disk 3 or the rubber-elastic band 161, a flat spring 181 made of spring steel or other springy material is used, which is arranged in a sliding manner in the elongated holes 458, 459 of the upstands 45, 46, 411, 412 of the pressure disk 404 and is guided over the support plate 171, 191, 203. The flat spring 181 can also be used instead of the rubber-elastic band 161 in Figure 14 together with the pressure disk.

- 31 -

404 can be used. The illustration in Figure 36 shows the fastening unit in the pre-assembled delivery state; if pressure is now exerted on the flat support plate 171 (191,203) during assembly using an auxiliary tool, the latter moves upwards, whereby the spring 181 slides in the elongated holes 458, 459 and gives way upwards so much that the support plate 171 (181,404 or 191,181,404) can be screwed into the hollow profile support 6. If the pressure P is then removed, the spring 181 slides back into the rest position and presses the support plate 171 (191,203) from above against the webs 62, 63, while the pressure disk 404 with its raised edges is pressed into the slot 61 and is pressed against the webs 62, 63 from below. This ensures that the support plate 171 (181,404 or 191,181,404) is clamped in the hollow profile support 6, but can still be moved along its longitudinal axis. Instead of the flat spring 181, a shaped spring made of spring wire can also be used, which fulfills the same function if designed accordingly.

Figure 37 shows a modification of the rubber-elastic disk coated with adhesive on both sides in the form of a round or square rubber-elastic molded part 501, consisting of two flat sides 37, 37', one upper side 37 of which is glued or vulcanized against the flat support plate 171 (191, 203) and the other side 37' against the pressure disk 4 (403, 404) and both sides 37, 37' of which are connected by a tubular rubber-elastic center piece 38. The molded part 501 thus flexibly connects the support plate and the pressure disk to one another. The elastic tubular center piece 38 replaces the effect of the rubber-elastic band 161, 1010 or the flat rubber-elastic molded part. The inner diameter of the tubular middle piece 38 is selected so that the threaded bolt 7 can be pushed through easily.

According to Figure 38, the lower side of a further shaped piece 502 facing the pressure disk 4 (403, 404) can be designed as a bead 391, which is inserted through the pressure disk 4 (403, 404), sits on the edge of the hole and in this way elastically connects the two parts so that the fastening unit can be easily inserted into the hollow profile support 6. The bead 391 is designed in such a way that, on the one hand, the rubber-elastic shaped piece 502 securely holds the support plate 171 (191, 203) and the pressure disk 4 together even when it expands, and, on the other hand, that when the lock nut 9 is tightened, the bead 391 slides into the hole in the pressure disk 4 and ensures that the fastening unit is securely fixed in the hollow profile support 6.

- 32 -

Figure 39 shows an embodiment of a further molded part 503, which partially or completely encloses the support plate 171 (191,203) and is firmly connected to it, e.g. by gluing or vulcanizing, and thus improves the captivity of the individual parts of the fastening unit.

In the case of small slot widths 61 in the hollow profile support 6, it may be useful to arrange the threaded hole 23 in the flat support plate 171, 191, 203 off-center or asymmetrically in relation to the width, so that slightly wider flat components can also be inserted into the slot 61 - then by holding it at an angle.

Instead of the one-sided or two-sided adhesive rubber-elastic disk 33, another endless rubber-elastic band 162 or a flat rubber-elastic molded piece can be arranged as a spacer between the pressure disk 4,403,404 and the support plate 171,191,203. These spacers have the task of making it easier to insert the fastening unit into the hollow profile support 6 by lifting the support plate over the webs 62,63 and enabling the support plate 171,191,203 to be easily screwed into the assembly opening 61 of the hollow profile support.

The endless rubber band is therefore advantageous both as a transport lock after packaging at the manufacturer and for the quasi-rigid, rotational movement of the support plate through the pressure disc. The rubber band also serves as a control when the threaded rod is turned to the left. The effort required is noticeably less and is a sign that it must not be turned any further. At the same time, the rubber band, like the elastic molded part, is a clamping element that pre-fixes the support plate and pressure disc and holds them together. When arranged as a spacer between the support plate and pressure disc, this predetermined distance between them enables the support plate to be locked into the hollow profile rail, even if the legs of the assembly opening are bent back at least once by 90 degrees, thus forming two parallel walls or edges the height of the first bend. The rounding of the support plate at two diagonally opposite corners, which first touch the legs of the hollow profile rail when screwed in to the right, also enables the fastening unit to be screwed in easily - even without a rubber band in between.
