Technical field

BACKGROUND OF THE INVENTION The invention relates to a connecting unit for connecting profile rails which are provided, at least in the connecting region, with a guide slot extending in the longitudinal direction, the connecting unit comprising a connecting plate with respective slots and connecting elements formed by screws and nuts for insertion into the slots and guides slots for fastening the joining plate to the profile rails, wherein at least one elevation is arranged around at least a portion of the slots, adapted to and insertable into the clear width of the guide slots, the slits in the joining plate being aligned with each other according to the desired joining angles of the profile rails and a side plate is associated with depressions on the top side of the connector plate to accommodate a portion of the nut, and wherein the connector plate is made of sheet metal and the elevations and depressions are formed in the sheet metal always with one embossing.

BACKGROUND OF THE INVENTION

The profile rails with a guide slot extending over their entire length are used for a variety of purposes. C-shaped profile rails are often used as profile rails, which are used in the creation of lightweight bearing walls. Since the profile rails are cut to the required length for a given application and the profile rails are arranged at different angles or angles to each other, connection options must be provided at the nodal points to ensure that the lightweight bearing wall has sufficient stability. Such profile rails can be used, for example, to bridge empty spaces by means of front wall panels intended to be placed in the carriage of the installation. Gauge plates are generally used as connecting means of profile rails, which simultaneously connect several profile rails to one another, in which the connection slots are always provided with fastening elements which engage the respective openings or slots provided with the tie plates. However, it has been shown during installation that the connection of the profile rails is relatively complicated in construction, since the more profile rails to be connected to each other by the gusset plate, the more difficult the correct alignment of the individual rails is. This fact even leads to the fact that at least two plumbers have to carry out this work when connecting several profile rails to each other.

SUMMARY OF THE INVENTION It is therefore an object of the invention to provide a connecting unit by means of which the connection of the profile rails can be carried out simply.

SUMMARY OF THE INVENTION

This object is achieved by a connecting unit for connecting profile rails which are provided at least in the connecting region with a guide slot extending in the longitudinal direction, the connecting unit comprising a connecting plate with respective notches and connecting elements formed by screws and nuts for insertion into the notches and guide notches for fastening the joining plate to the profile rails, wherein at least one elevation is arranged around at least a portion of the notches, adapted to and insertable in the width of the guide notches, the notches in the joining plate being aligned with each other according to the desired joining angles of the profile rails and the joining plates are associated with recesses on the top side of the joining plate to accommodate a portion of the nut, and wherein the joining plate is made of metal sheet and the elevations and recesses are formed in the sheet ENA always along one embossment according to the invention, which is characterized in that the slots are formed as longitudinal slots open at the edge of the connecting plate, whereby the elevations and / or depressions are always at the closed end of a notch formed in a substantially circular shape.

- 1 GB 292095 B6

The elevations provided on the connecting plate serve essentially as a quasi-guiding of the profile rails, since the elevations are inserted substantially aligned in the respective guide slots. Obviously, even when using two elevations for one profile rail, its position can only change in one spatial direction. When the profile rails are cut or cut perpendicularly to their longitudinal direction, it is even usually sufficient if the profile rail is precisely aligned with only one elevation and by placing its face on the side surface of the other profile rail. This also ensures that the end faces of certain profile rails can automatically form stop surfaces for other profile rails, so that their position and relative to each other is clearly determined. This greatly reduces the installation effort, since the installer must connect the profile rails to each other only by fitting the guide slots on the elevation and tightening the fastening means. Subsequent alignment of the profile rails is virtually eliminated.

Advantageously, all open ends of the longitudinal slots of the connecting plate can be turned away from each other. The notches open on one side allow the screw located in the profile rail to be inserted, so that the screw does not have to be uncomfortably pushed through the closed hole in the connecting plate first and then inserted into the guide slot of the profile rail. The recesses opposed to the elevations in the joint plate have the particular advantage that by slightly tightening the nuts on the bolts, the elevations are already best positioned in the guide slots of the profile rails, yet the profile rails can still be moved without changing the joining elements of screws and nuts. its position relative to the connecting plate. This provides an enormous simplification of the handling of the coupling unit, since the coupling elements formed by the bolts and nuts cannot slide out of the longitudinal guide notch during alignment. Therefore, the plumber does not have to pay attention to this fact either.

The design of the elevations and / or depressions at the closed end of the substantially circular-shaped notches ensures that the profile rails can be mounted on the elevations under various inclinations. The circular shape of the recess, on the other hand, prevents the nut from sliding in the longitudinal guide slot, but at the same time ensures that the nut can be further tightened.

According to a preferred embodiment, the elevations may have a height that is less than the height of the guide notch. This ensures that even the simplest standard bolts can be used for fastening, since both the bolt head and the nuts of the respective fasteners can lie flat on the respective elements when fastening, without, for example, taking precautions on the elevation nut .

According to a further preferred embodiment, the screws may be so-called round head screws under which a square is provided, the square being inserted into the notch in the connecting plate non-rotatably. This embodiment has the advantage that once the round head screw is inserted into the guide slot of the profile rail, it is held non-rotatably in the guide slot so that the installer does not need any additional tool to secure the screw head against rotation.

In order for the nut to be inserted substantially into the recesses, the nut may be provided with a cylindrical guide extension which is inserted into the recesses substantially aligned.

In order to be able to use standard socket head screws when connecting thin-walled profile rails and thin-walled connecting plates, the nut can be provided with a recess, in particular intended to be placed in the quadrilateral under the semi-round head of the screw. This ensures that, independently of the thickness of the connecting plate and the profile rail, a suitable standardized head screw can be used for their connection, which locks non-rotatably in the guide slot of the profile rail.

In all cases, the profile rails can advantageously be designed as C-shaped profile rails which are clamped to the connecting plate by means of a hemispherical screw head.

-2GB 292095 B6

C-shaped sectional rails are advantageous because they are relatively inexpensive. In addition, common dimensions have been established with these C-shaped profile rails.

Since, in order to form the light support wall of the profile rail, it is usually arranged perpendicular to one another, it is advantageous according to a further embodiment of the invention that the cuts in the connecting plates, including depressions and elevations, are arranged in two or three rows perpendicular to each other. It is therefore possible to create both perpendicular connections in one plane and three-dimensional connections very quickly with such a suitable connecting unit.

In order to connect several parallel C-shaped profile rails to one another, it is advantageous according to another embodiment of the invention if the distance between the centers of the depressions and the elevation in one row of slots corresponds substantially to the sum of half the widths of the C-shaped profile rails. that C-shaped profile rails of different widths can be connected to each other. The elevations and depressions in the connecting plates are then arranged accordingly.

A simple method for producing elevations and depressions in the joint plate is, according to a further variant, in that the joint plate is made of metal sheet and then the elevations and depressions are formed together by pressing the sheet together. It is therefore possible to create elevations and depressions at the same time in the connection plate by means of one indentation.

A further variant consists in that the connecting plate is provided with an attachable connecting bracket, which is also provided with elevations arranged at a distance from each other and arranged around the fastening notches, at least two of which are each arranged in the connecting bracket arm and can be fitted into the recesses in the connecting circuit board. For this purpose, the spatial arrangement of, for example, C-shaped profile rails can be carried out in a simple manner, the alignment of the C-shaped profile rails with respect to each other being automatically carried out with respect to a predetermined angle given by the joining bracket. and depressions in the connecting plate.

DETAILED DESCRIPTION OF THE INVENTION

The front wall panel 1 used for the plumbing installation may be modified for various purposes, as shown, for example, in Figures 1, 3 and 4, where the front wall panel 1 for WC installation is illustrated, and in Figures 5 and 6, where a front wall panel 1 for fastening the sink and fittings is shown. The embodiments will be described in more detail below. However, completely different designs of the front wall panels are also possible, especially for superstructures which are adapted to different applications, for example for showers, baths, urinals, bathroom furniture, etc.

The front wall panel 1 consists of a frame 2 formed of two vertical struts 3 made of hollow profiles, and one cross strut 4 made of an open hollow profile, in particular a C profile, which holds the vertical struts 3 apart from each other. As can be seen in particular from FIG. 7, the hollow profile of the vertical struts 3 is in particular a box profile made by bending, in particular of a rectangular cross-section, with a longitudinal web 5 arranged in the middle of the shorter side of the cross-section. The longitudinal web 5 is three times more thick than the other parts of the hollow profile because it is formed by bending one end of the sheet over the other. The material used is preferably a galvanized steel sheet which is coated with a lacquer layer or coated with a color foil prior to profiling.

The profile C of the cross strut 4 and the box profile of the vertical struts 3 in this embodiment preferably have the same internal cross-sectional area. The respective end openings 6 and 7 of the vertical strut 3 and the cross struts 4 serve as plug-in arrangements for a corner plug-in coupling 8 which, with its plug-in extensions 9 and 10, extends substantially into the end-openings 6 and 7. the extensions 9, 10 are arranged at an angle of 90 ° to each other so that the corner plug connector 8 is L-shaped, the arms of which are the plug extensions 9, 10. The corner plug connectors 8 form at least the upper corners of the frame 2. forming a visible corner. For this purpose, this central part 11 is preferably adapted to or extends to the outer contour of the vertical struts 3 and the cross struts 4. With this embodiment, stop surfaces 12 are formed on which the vertical struts 3 and the transverse strut 4, which are cut perpendicular to their longitudinal axis, lie flat. Dimensional accuracy is therefore automatically maintained when assembling the struts 3, 4 with the corner plug connector 8.

Each insert 9, 10 is further provided with a threaded bore 13, 14 arranged perpendicular to the insertion direction, in which a suitable screw for fastening to the struts 3, 4 is screwed in each time. , parallel to its longitudinal axis. The vertical strut 3 may for this purpose be provided with an opening 16. For example, the mounting on the vertical strut 3 may also be carried out by screwing a countersunk head screw that does not protrude above the outer surface of the insert 9 into the threaded bore 13. a diameter which is smaller than the head of the screw used but large enough to guarantee access of the tool to the head of the screw. The screw head can then be pressed against the inner wall of the vertical strut 3 with the corner plug connector 8 inserted by unscrewing the screw. In this embodiment, the attachment of the corner plug connector 8 to the vertical struts 3 can also be made from the front side of the frame 2, since the fastening means do not protrude.

-5GB 292095 B6

Figures 8 and 9 show that the corner plug connector 8 can be designed with its plug-in extensions 9, 10 as an aluminum die-cast or plastic injection-molded part and can therefore be provided with suitable reinforcing ribs and cavities 17 to prevent material buildup.

In the middle portion 11, the corner plug connector 8 has a through-hole fastening point 18 through which the bolt 19 is pushed onto the shaft of which a spaced circlip 19a is provided for rotatably mounting the bolt 19 in the through-hole, the thread of the bolt 19 extending over the rear side of the corner plug connector 8 over a long distance, for example 10 cm. The screw 19 forms the axis of rotation of the fastening tab 20, which is provided with a threaded sleeve 21 for screwing in the bolt 19. The fastening tab 20 serves to fasten the front wall panel 1 to the wall and is provided with a longitudinal bore 22 therethrough. wall mounting. By rotating the screw 19, the distance of the fastening tab 20 from the frame 2 can be adjusted so that the front wall panels 1 can be provided at a relatively large distance from the wall. FIG. 8 shows the various screw-in phases.

According to a further variant, shown in Figs. 7a and 7b, an intermediate snap ring 19b is inserted into the through hole in the corner plug connector 8 so as to secure the screw head 19 axially in the through hole. The screw 19 is then rotatably mounted in the corner plug connector 8. The main supporting force is transmitted by a nut 19c screwed onto the thread of the bolt 19 and a washer 19d which abut the vertical strut 3.

FIG. 8 further illustrates that the fastening tab 20 may also be made as an aluminum part made by die casting or as a plastic element. It is also apparent from FIG. 8 that a hook-shaped element 23 is disposed on the rear side of the fastening tab 20 and is offset from the abutment surface of the fastening tab 20. The hook-shaped element 23 can be suspended in the corresponding guide opening of the C-shaped profile rail fixed to the mounting wall. As a result, the assembly of the front wall panel 1 can be greatly simplified. Optionally, it can be fastened to the C-shaped profile rail through the opening 24. It also follows from FIG. 9 that the fastening tab 20 may also be provided with several longitudinal openings 22 to increase the number of different fastening options. Since the fastener 20 is pivotable about an axis of rotation in the middle portion 11 of the corner plug connector 8, it can be positioned in a variety of positions on the mounting wall.

The end portion 25 of the fastening tab 20 disposed around the threaded sleeve 21 is provided with a curvature concentric to the axis of rotation whose radius substantially corresponds to the shortest distance A of the axis of rotation in the corner plug connector 8 to its outer edge or upper edge of the cross strut 4. This ensures that the upper edge of the end portion 25 and the upper side of the corner plug connector 8 lie together in a plane perpendicular to the front side of the frame 2. This is particularly advantageous when the upper side of the front wall panel 1 is to be used as a support for the storage the surface arranged on it. The elements that make up this storage surface, such as gypsum-cement or plasterboard, then also abut the abutment region of the end portions 25 in the wall region and are automatically aligned at an appropriate angle to the front of the front wall panel L

The aforementioned plug structure of the frame 2 has the further advantage that the struts 3 need not be welded to each other in a further operation. By simply interlocking these parts together, both a stable and at the most precise design of the frame 2 are formed, so that the alignment of several front wall panels 1 due to the high dimensional stability does not present any difficulties as in the prior art. Moreover, the positioning of the front wall panels 1 by means of rotatable fastening tabs 20 mounted on the corner plug connectors 8 is greatly simplified. For the sake of completeness, it should be added that the location of these fastening tabs 20 may be

-6GB 292095 B6 at completely different locations on the front wall panel 1 to suitably support the superstructures.

5, 6, 11 and 12, one embodiment of the front wall panel 10 is shown, in which the lower end openings 6 of the vertical struts 3 serve to accommodate substantially aligned guide rails 26 which are telescopically inserted into the vertical struts 3 and are held here. The guide rails 26 are arranged perpendicular to the longitudinal direction of the lower cross strut or lower rail 27 and are fixed thereto. In the exemplary embodiment shown in these figures, C-shaped sectional rails are used as guide rails 26. The lower rail 27 is provided with mounting holes (not shown) for attachment to the lower installation portion or C-shaped sectional rails mounted thereon. A hole 16 is also provided in the lower end portion of the vertical struts 3 through which the bolt 28 is inserted. A specially formed clamping nut 29 is provided inside the vertical struts 3, provided with a threaded bore 30 for screwing the bolt 28. inside the lower end portion of the vertical struts 3. The clamping nut 29 is approximately V-shaped in cross-section, thereby substantially forming two clamping arms 31. At one end of the clamping nut 29, a pin 32 is provided on which a spring bracket 33 is pressed. This spring yoke 33 has two spring arms 34 which spring perpendicular to the insertion direction of the guide rails 26.

The clamping nut 29 is designed such that after loosening of the screw 28 it can be inserted into the inside of the guide rail 26 and is still connected to the vertical strut 3 by means of the screw 28. The screw 28 passes through the guide notch 15 in the guide rail 26. in particular from FIG. 12, where the screw 28 is not shown. By tightening the screw 28, the clamping arms 31 are then pressed against the guide rail 26 and clamped against the vertical strut 3. The spring yoke 33 now acts so that the spring arms 34 already exert a spring force on the side of the guide rail 26 when the clamping nut 29 is released. the elastic force is preferably selected such that the entire front wall panel 1 does not automatically adjust by loosening the screws 28 but remains held in position. The displacement of the guide rails 26 in the vertical struts 3 can only be effected after a certain force has been applied, which, however, gives the installer particular advantages in the assembly of the front wall panels 1, since they do not need to be fixed in the extended position. By tightening the screws 28, the position or the exact height of the front wall panel 1 is then fixed. By means of the adjustment region thus created, the flexibility of the front wall panel 1 can be greatly expanded in terms of location at different heights. The plumber is not bound to certain heights of the front wall panels 1 and can adjust these wall panels 1 according to the customer's wishes. It should be added that the clamping nut 29 can also be designed as an die-cast aluminum part or as a injection-molded plastic part with correspondingly bent leaf springs, and the clamping nut 29 can be provided with ribs and cavities to prevent material buildup.

The above-described embodiment with telescopically extending guide rails 26 has the advantage that, in installations or extensions that are as high as the whole wall, two or more front wall panels 1 can be arranged on top of each other such that the ends of the vertical struts 3 provided with guide rails 26 so that the lower strip 27, which is usually lower at the front wall panel 1, is now located at the top and can be connected to the corner of the room, see also FIG. 2, right side. With this embodiment, it is possible to compensate for variations in room height by appropriately extending the guide rails 26 or sliding them into the vertical struts 3.

1, 3, 5 and 13 further show that the front wall panel 1 is also provided with a plurality of rungs 35. which are substantially parallel to the cross strut 4 and which are rigidly connected to the vertical struts 3 and are used in particular for fastening and location of extensions. As already mentioned, the vertical struts 3 have a longitudinal web 5 arranged along their length, which has three times the wall thickness than the other sections of the profile, see also FIGS. 14 and 15. This three times the longitudinal web 5 gives it a particularly high strength and I will support 3 with sufficient rigidity. Furthermore, the longitudinal web 5 is provided with a series of rectangular snap holes 36,

- 7GB 292095 B6 arranged along the entire length of the vertical struts 3. The latching holes 36 of the two vertical struts 3.

forming together the frame 2 are each arranged at the same height. The mean distance or spacing of the two snap openings 36 is preferably chosen to be very small in order to provide as much fit as possible on the longitudinal web 5. According to a preferred embodiment, the pitch is about 1 cm.

The crossbar 35 is essentially made of U-bent sheet metal, each having a latching projection 37 at its end to engage the latching holes 36. For this purpose, the web U of the cross-section 35 is separated from the legs 39 and by bending it inwardly, a step 38 is formed, so that an approximately H-shaped profile is formed in the end portions. The legs 39 are molded to form snap lugs 37 and recesses 40. The dimensions of the recesses 40 are chosen such that their depth is less than the longitudinal thickness. However, its width can accommodate the front portion of the longitudinal web 5 with the latching projection 37 engaged. The end portions of the partition 35 are each associated with a locking plate 41 with a screw 42. This locking plate 41 is latched into the latching holes 36 when the latching lugs 37 are latched. rests on a staggered back offset into The seating surface 43 of the arms 39. The screw 42 is screwed into the threaded hole 44 in the end portion of the crossbar 35. In this way, the crossbars 35 can be arranged at any height of the frame 2 depending on the plurality of latching holes 36, obtained by simply inserting or latching the latches. the projections 37 in the snap holes 36 and tightening the screw 42 with the locking plate 41. In this connection it should also be noted that, for the sake of simplicity of installation, suitable marking strips or stickers can be provided on the vertical struts 3. for example, partitions for toilet or shower.

Furthermore, it has already been stated that the transitions 35 thus made can only be used for numerous superstructures with slight modifications. For this purpose, the crossbar 35 is provided in its central part with receiving holes or threaded holes, respectively. However, this will be described in more detail elsewhere.

However, it should be added that in the figures it is not shown that at least one soundproofing element is provided between the longitudinal web 5 and the crossbar 35, designed to damp the vibrations coming from the elements located on the crossbar 35, in particular from their operation.

It is apparent from FIGS. 1, 3, 4, 16 and 19 that a suitably designed adapter 46 is provided on both sides of the flushing tank 45 between the two vertical struts 3. This adapter 46 has the advantage that it allows the connection of various flushing tanks 45 to This adapter 46 is, like the flushing tank 45, made of plastic and can therefore be embodied in one piece by a very simple injection molding technique. The adapter 46 consists of a base plate 47 intended to be placed on a respective flange strip 48 provided on a flush tank 45. The base plate 47 is provided with T-shaped elements 49 which are inserted into respective holes 50 in the flange strip 48 and engage with their hook-shaped edges. In order to prevent unintentional unhooking of the T-shaped elements 49, U-shaped notches 51 are provided in addition to the T-shaped elements 49, thereby forming resilient pressure lugs 52 which extend into the flange-shaped plate 48. the longitudinal side of the ribs 53, 54 arranged perpendicular to each other. These ribs 53, 54 are also provided, as shown in particular in FIG. 16, with a U-shaped recess 55, thereby forming on the vertical arm 53 two elastic tongue elements 56 arranged perpendicular to the base plate 47. On the side of the elastic tongue elements 56 facing away from the base plate 47, three triangular snap-in elements 57 are provided. On the base surface 58 of the arm 54 parallel to the base plate 47, frusto-pyramidal snap-in pins 59 are provided, the size and spacing of which are selected so that they can snap into In order to allow the triangular engagement elements 57 to engage behind the longitudinal web 5 against the base surface 58 of the arm 54. the distance between the base surface 58 from which the snap pins 59 protrude and the triangular

This is particularly evident from FIG. 20. With the aid of the adapter 46, a conventional flushing tank 45 can now be attached to the vertical struts 3 of the front wall panels 1 in a simple manner. The disengagement of the adapter 46 from the longitudinal web 5 is also very simple, since the triangular engagement elements 57 are provided with inclined leading surfaces for both removal and insertion. Another advantage of the plastic adapter 46 is that it also serves as a sound insulation element.

Referring now to Figures 2 and 21 to 26, variants of the connection of open hollow sections, in particular C-shaped section rails, will be described.

Fig. 2 shows that when installing the front wall panels 1 between the individual required superstructures along the mounting wall, it is also necessary to bridge the voids, which will also be covered with gypsum-cement or gypsum boards arranged on the front wall panels 1 . In order to guarantee sufficient support for these panels, profile rails 60 are preferably arranged between the individual wall panels 1, preferably in the form of C-shaped profile rails. In order to enable the installer to easily install these profile rails 60, a suitable connecting unit is provided. essentially from a connecting plate 61 which is provided with slots 62 open at the edge of the connecting plate 61, and of screws 63, in particular, square head screws 68 with a square 69 underneath this round head inserted in these slots 62, with respective nuts 64. Notches 62 they are provided at their closed end with approximately circular embossments 65, so that on one side of the connecting plate 61 an elevation 66 is formed and on the other side a recess 67. The diameter D of the elevation 66 is chosen to correspond substantially to the width of the guide notch 15 C to be connected. The height E of the elevation 66 is chosen to be equal to or less than the wall thickness of the connection strut 60. Preferably, the height E is only slightly smaller. The head screw 63, which is preferably used for connection, preferably has a lens-shaped head 68 whose diameter is greater than the width of the guide notch 15 of the profile bar 60. Therefore, the end portions that guide the notch 15 of the profile bar 60 may be loose. They define, when the screw 63 is loosened, between the lower side of the head 68 and the connecting plate 61. In this case, the profile rails 60 are guided substantially by the elevation 66. The screw 63 is provided with a square 69 under its head 68, which is slidably guided in a notch 62 of the connecting plate 61, but cannot rotate therein. The hex nut 64 is provided at its end facing the connecting plate 61 with a guide extension 70 which can be inserted into the recesses 67 substantially flush. It is now apparent from this embodiment that the connection of the connecting plate 61 to the connecting strut 60 can be made very simply and in certain circumstances even with only one hand.

When using a conventional pan head screw 63, the nut 64, as shown in FIG. 22, may be provided with a recess 71 for partial placement of the doubles 69. In order to connect the same profile rails 60 to each other, the distance C corresponds to the center of the depression. 67 and the elevation 66 to each other substantially the width G of the profile rail 60. The notches 62 including the recesses 67 and the elevation 66 are arranged in two rows arranged perpendicular to each other. In the illustrated embodiment, three notches 62 are arranged in one row and two notches 62 are arranged in the second row. The connecting plate 61 is therefore approximately triangular in shape because the two notches 62 row is arranged perpendicular to the center of the three notches 62 row. so that its central notch 62 belongs to another row at the same time. The open sides of the slots 62 are always spaced apart. The connecting unit can also be used for connecting two different profile rails, for which the respective dimensions must be appropriately changed.

23 to 25 show some variants of the connection.

FIG. 23 shows a connection point in which two profile rails 60 are mounted on one through profile rail 60 and are perpendicular to it from two sides. By guiding the elevations 66 in the respective guide slots 15 in the profile rails 60, they are automatically

292095 B6 of the row of notches 62 in the connector plate 61 arranged parallel and perpendicular to the through profile rail 60. The movement of the connector plate 61 along the guide slot 15 is very simple when the screw 63 and the nut 64 are loosened. Since the profile rails 60 are always cut precisely perpendicular to their longitudinal distribution, the ends of the two profile rails 60 connected to the continuous strut 60 can rest against this continuous profile strut 60, in addition being always guided in addition by a corresponding elevation 66 of the connecting plate 61. This extremely simplifies alignment of the profile rail 60.

FIG. 24 shows a connection point where two perpendicular profile rails 60 are connected perpendicular to each other. FIG. 24 shows that the connection plate 61 has a triangular shape with two equally long arms that make an angle of 90 ° to each other. . Thus, the third arm is arranged at an angle of 45 ° to the two first arms. The axes passing through the centers of the depressions 67 and the elevations 66 located at the apexes of this triangle are always arranged parallel to the arms, so that the profile rails 60 are automatically fixed at right angles, as shown in Fig. 24. such that the shortest distance K between the circumference of the depressions 67 arranged on the triangle switch and the axis passing through the depressions 67 to which the depressions 67 located on the triangle switch does not correspond to half the width of the profile rail 60. 60, used for management purposes. This fastening method further shows that only two screws 63 and two nuts 64 are required to achieve a stable fastening.

FIG. 25 shows a connection variant in which two frames 2 of the front wall panels L are connected to each other. To this end, two fastening points 18, two threaded holes 13, 14 and a hole 16 in the vertical struts are required to connect the connecting plate 61. 3. The spacing of the threaded holes 13, 14 and the opening of the fastening point 18 in the corner plug connector 8 are selected as desired.

FIG. 26 shows an embodiment in which the connecting plate 61 is slightly modified. In order to be able to connect the profile rails 60 even in two perpendicular planes to one another, the portion 72 of the connecting plate 61 is angled 90 ° from the basic plane of the connecting plate 61 so that the recess 73 thus substantially corresponds to the outer dimensions of the profile rail 60 to be connected. The section 72 is also provided with a notch 62 with a corresponding elevation 66 and a recess 67, which is further arranged in line with the at least one notch 62 in the base plane of the connecting plate 61, although offset by 90 ° upwards. In this way, it is possible to connect, for example, one vertical continuous profile rail 60 with two connecting struts 60 which bear against it at their ends, without the need for special alignment, since the two connecting struts 60 which are adjacent to each other are automatically adjusted by a continuous profile rail 60 flush.

In the variant of FIGS. 26a and 26b, a connecting bracket 161 is provided that attaches to the connecting plate 61 and which, like the connecting plate 61, has in its arms around the notches 162 recesses 65 to form elevations 66 and depressions 67. Angle between the arms of the connecting The angle bracket 161 is preferably 90 [deg.], so that the advantageous spatial arrangement of the profile rails 60 formed by C-shaped cross-sections can be carried out. In order to achieve an accurate alignment, the two elevations 66 assigned to each other The distance of the protruding leg of the joining bracket 161, which is precisely spatially positioned by the elevations 66 in the second leg inserted into the recesses 67 in the joining plate 61, from the parallel edge of the joining plate 61 is opposite. It essentially controls the width G of the C-shaped cross-section used to form the connection strut 60. The use of a separate connection bracket 161 together with the connection plate 61 provides numerous possibilities of combining their configurations, thereby extending the functionality of the front wall panel 1 accordingly.

The connecting plate 61 is preferably made of sheet metal, and the elevations 66 and depressions 67 are formed by embossing 65. However, the connecting plate 61 can, of course, also be made of completely different materials and other manufacturing methods.

Referring to FIGS. 1, 10 and 27 to 30, the use of a connecting bracket 74, which can also be used as a connecting element, will be described. The connecting bracket 74 has a substantially flat bearing surface 75 and a mounting surface 76 and a support surface 77 arranged perpendicular thereto. The mounting surface 76 and the support surface 77 are each provided with two fastening slots 78 open on one side. The open side of the fastening notch 78 faces away from the abutment surface 75. The median distance L of the two fastening notches 78 of the fastening surface 76 and the abutment surface 77 corresponds to the width G of the C-shaped cross section connected by the connecting bracket 74. furthermore, the distance M from the bearing surface 75 to the axis of the bolts later inserted into the fastening slots 78 is substantially half the width G / 2 of the C-shaped cross-section. The bearing surface 75 lies flush with the upper side of the cross strut 4 or the end portions 25 of the fastening tabs 20. FIG. 27 further illustrates how two C-shaped cross-section profiles can be connected to each other by this connecting bracket 74. Connecting bracket 74 allows connection The design of the C-shaped cross-sectional profiles in two planes provides a number of connection options by corresponding arrangement of the connecting angle 74. Furthermore, the connecting bracket 74 can be very well used for engaging and fastening cover elements, for example gypsum fiber-cement or gypsum boards, intended to be fastened to the front wall panel 1.

Further, two rows of projections 80 are arranged on the connecting bracket 74 on the mounting surface 76 and the abutment surface 77, substantially parallel to the abutment surface 75. The distance P of the outer edges of the projections 80 in two rows corresponds to the width of the guide slot 15 in the strut 4; Furthermore, the axis of symmetry of the two rows of projections 80 has a distance M from the bearing surface 75, which substantially corresponds to half the width G / 2 of the C-shaped cross-section. The projections 80 serve to guide and align the connecting angle 74 in the profile. By means of the guide notch 15 of the strut 4, or the profile bar 60 formed by the C-shaped cross-section profile. This makes it possible to align the connecting angle 74 very easily on the strut 4, 60 and connect it to the struts 4 or the profile 60 by screw.

The seating surface 75 is provided with an access opening 82, approximately L-shaped, the arms of which are arranged parallel to the mounting surface 76 and the support surface 77. The access opening 82 allows the tool, in particular the wrench, to be accessed to the fastening means, i.e. 79 and a nut 81 located in respective mounting slots 78. Furthermore, the access opening 82 serves as a mounting opening for wall mounting and overhead mounting. For the sake of completeness, it should be added that mounting holes 75 and projections may be provided on the bearing surface 75, as shown in FIG. 28, but this need not necessarily correspond to the dimensions of the mounting slots 78 on the mounting surface 76 and the support surface 77. the abutment surface 77 is each provided with apertures 76a, 77a which serve to be fastened to lightweight bearing walls, in particular by means of self-tapping screws.

The connecting angle 74 is preferably made as a bent sheet metal part as shown in the figures. It follows from the above that the connecting angle 74 as a multifunctional element can simultaneously perform several tasks. On the one hand, it serves as a bearing surface on the front wall panel 1 and, on the other hand, it can be used for many different variants of the connection of struts 4, 60 formed by C-shaped cross-section profiles.

1 to 4 and 31 to 33, a variant of a partition 35 intended to accommodate WC superstructures will be described in more detail below.

-11 GB 292095 B6

The crossbar 35, as already described above, consists of a beam which is substantially U-shaped in cross-section.

This crossbar 35 is further provided with recesses 83 in its arms 39. Both arms 39 are supported by a connecting plate 84 which is connected to them by means of screws. The connecting plate 84 extends downward beyond the cross-member 35 and is approximately T-shaped, see FIG. 32. The upper T-shaped transverse portion covers the cross-member 35 on its rear side and thus improves its torsional strength.

By the recess 83 of the rung 35, the tongues 84 are each associated with spring plates 85, which are each formed in one piece with the manifold plate 84. The spring tongues 85 are provided with protrusions 86 in their end portion facing away from the fixed end. These protrusions 86 are each located in the region of the recesses 83, as in the illustrated embodiment, somewhat below the recesses 83. The recesses 83 form a guide bearing which is covered by the connecting plate 84 and which is intended for sliding bearing of the guide plates. For each front wall panel 1, two guide posts 87 are provided on the bottom rail 27 and are fixed thereto. The guide posts 87 extend parallel to the vertical struts 3 and have a width and a thickness such that they are substantially flush with the recesses 83 or the guide seat. In order to form the guide posts 87, preferably U-shaped flat steel is used to at the same time achieve a bending stiffness in the load direction and a relatively low weight structure. On the connecting plate 84 are provided cover elements 88 guided in the extension of the guide bearings. This can be achieved either by the plate located on the crossbar 35 or the connecting plate 84 or, as shown in FIG. 31, by two substantially U-shaped sheets. The guide posts 87 located in the guide bearings are acted on by spring-mounted projections 86 As shown in FIG. 33, the resilient force, so that displacement of the lower ledge 27 or guide posts 87 relative to the crossbar 35 and hence relative to the entire frame 2 of the front wall panel J, can only be achieved after a predetermined force has been overcome. This force is preferably selected such that there is no displacement due to the weight applied to the front wall panel 1.

The locking of the crossbar 35 with the connecting plate 84 relative to the lower bar 27 is provided by a stop device which is height adjustable and protrudes from the lower ends of the vertical struts 3. The stop device consists essentially of a threaded rod 90 projecting in extension from the vertical struts 3. of these by means of the adjusting nut 89 can be screwed or unscrewed. For this purpose, a stopper 91 is fixed at the lower end of each vertical strut 3, which allows the threaded rod 90 to pass through, while being a support for the adjusting nut 89. The stopper 91 can rest on a collar on the front side of the vertical strut 3 or 3 by another fastening means. The lower end of the threaded rod 90 rests on the lower bar 27. The adjusting nut 89 is designed as a hinged nut for quick adjustment, so that the installer can adjust very quickly. The threaded rod 90, in conjunction with the adjusting nut 89, allows a very precise and fine adjustment of the desired height of the crossbar 35 and the connecting plate 84.

To fasten the respective extension parts, either the fastening plate 84, see Fig. 32, or the cover elements 88, see Fig. 1, are provided with corresponding threaded fastening holes, for which, in the embodiment shown in Figs. 31 to 33, The front side of the cover elements 88 are flush with the front side of the crossbar so that the pressure exerted by the extension elements can be distributed over a wide area. 35. For example, since very large bending moments can be applied when the wash basin is suspended, the cover elements 88 rest on the guide posts 87, whereby the deflection is very easily maintained.

However, if, due to the high load, the permissible deformation needs to be limited to a certain value even at higher bending moments, a support leg 94 supporting these parts can be provided to further support the crossbar 35 or the connecting plate 84, see FIG. installed on the floor and fastened on the back of the listed parts. It is also possible to support the crossbar 35

- 12GB 292095 B6 by means of fastening tabs 20 disposed thereon. The construction and function of the fastening tabs 20 have been described above.

In order to improve the guidance of the guide post 87, a further rung 35 may be provided with corresponding recesses 83 for receiving the guide post 87 in the lower end portion of the vertical struts 3.

The attachment of the crossbars 35, under certain circumstances when using sound insulating elements, is also described above.

FIG. 33 shows that the fastening of the cover elements 88 to the attachment plate 84 is accomplished by means of fastening lugs 104 which are inserted into respective receiving openings 103 and which can be bent. Holes resulting from the formation of the flexible tongues 85 can also be used for this purpose. This is particularly the case when both the connecting plate 84 and the sliding elements 88 are made of sheet metal by pressing and bending. The spring tongues 85 can then be made in the manifold plate 84 by simple pressing and bending.

The cover element 88 (see FIG. 1) or the connection plate 84 (see FIG. 32) is provided with a receiving opening 95 for receiving and passing the supply pipe 96 from the flushing tank 45. To provide sound insulation, a ring is provided in the receiving opening 95. In addition, there is provided a bracket 98. See Fig. 1, which is preferably made of plastic, and which is fastened by a clip 99 on the lance 96. A releasable snap-on is further provided on the bracket 98. a bracket 100, by which the outlet pipe 101 is fixed in the holder 98, and at the same time a sound insulation is provided.

For the sake of completeness, it should be added that the threaded mounting holes 92 in the connection plate 84 are disposed in the resilient tongues 102 so that the resilient tongues 102 are tightly tightened to the guide posts 87 by tightening the screws and therefore additionally contribute to a more secure alignment of the attachment elements. The resilient tongues 102 also assume the function of compensating for manufacturing tolerances.

Furthermore, an embodiment is possible in which the arrangement of all attachment elements on the frame 2, whether by means of crossbars 35 or other elements, for example an adapter for the flush tank 45, is carried out using sound insulating elements. In addition, the elements themselves, for example the adapter 46, can simultaneously constitute sound insulation elements. These measures lead to a significant reduction in noise generation and therefore benefit the health of the downstream user more.

34 and 35 show a variant of the partition 35, in which the sound insulation is preferably provided. The crossbar 35 consists of a base body 105 which has numerous possibilities of fastening fluid flow parts, represented by openings 106, 107 and 108. This crossbar 35 is intended, for example, for fixing fittings as shown in Figures 5 and 6. End portions 109 of the base body 105 facing the vertical struts 3 are always fastened to the connecting piece 111 by plastic bolts, each with a damping element 112 inserted therein. The connecting piece 111 has a bent cross section with substantially parallel end flat arms 113, 114. The first end flat arm 113 overlaps This damping element 112 is provided with screw holes 110. In the second flat end arm 114, fixing holes 115 are provided, which are spaced according to the spacing holes 36 in the spacing. longitudinal web 5 vertical spans r 3. For the connection bars 35 to the vertical struts 3 is used more locking plate which is not illustrated, which is similar to locking plate 41, so that the longitudinal bars 5 vertical struts 3 is located between the second end 114 of the flat arm and this locking plate. This locking plate (not shown) is preferably provided with at least one latching projection which extends into the latching hole 36. The sound insulation achieved by this variant of the partition 35

- 13 GB 292095 B6 meets the highest permissible noise requirements. In addition, separate sound insulation of each component is not necessarily required, but can be modified.

Numerous possibilities of mounting the front wall panels 1 by means of the above-described means are particularly evident from FIG. 2. This gives various possibilities for the arrangement of sanitary installations.
