Definitions
- the invention relates to a control cabinet for wall mounting with a mounting hole having a rear wall.
- switch cabinets are to be attached to a wall, it is necessary in the known switch cabinets to remove mounting plates located in the switch cabinet in order to get to the rear wall of the switch cabinet.
- the rear wall of the control cabinet is usually provided with holes through which the control cabinet is attached to the wall, the screws being screwed into the wall from the inside through the rear wall. Only then can the control cabinet be completely rebuilt.
- An alternative solution is to attach fastening hooks to the back of the control cabinet. And with this method, it is necessary to attach it from the interior of the control cabinet.
- the known control cabinet for wall mounting is therefore very complex to handle, which is also reflected in the assembly costs.
- the object of the invention is therefore to provide a control cabinet of the type mentioned in the introduction, in which the wall mounting is made significantly easier.
- the rear wall designed in this way enables the control cabinet to be attached to the wall without having to be disassembled beforehand, but it is possible to prepare the rear wall from the outside.
- the fastening hole in the rear wall as a through opening can also be designed as a blind hole, for example if hermetically sealed control cabinets are involved.
- the thread provided in the fastening hole makes it possible to establish a firm connection with the control cabinet from the outside of the rear wall and thus to fasten it to a wall.
- the hole reveal of the fastening hole is advantageously provided with the thread.
- sleeves having an internal thread are inserted into the fastening holes.
- the use of sleeves has proven itself in practice, as these can be easily and quickly inserted into the mounting holes.
- rivet nuts can be inserted into the fastening holes. Rivet nuts have also proven themselves in practice, especially since a stable connection to the rear wall is established, which is sufficient to fasten the control cabinet to the wall.
- the internal thread inserted in the fastening holes extends beyond the outside and inside of the rear wall. Due to the internal thread extending over the outside or inside of the back wall, protection of the back wall is achieved in particular during further processing, since the back wall does not lie directly on the outside or inside and can be damaged, but instead the inside thread takes over Spacer function, which lifts the rear wall sufficiently from a surface.
- At least one mounting element can be fastened to the outside of the rear wall by means of a screw inserted into the internal thread.
- Each fastening hole can preferably be connected to a mounting element.
- the mounting element can be designed as a hanging bracket.
- the mounting element can also be designed as a mounting bracket with two longitudinal legs arranged parallel to one another, which are connected to one another via a connecting leg. Both designs of the mounting element enable the control cabinet to be easily and easily attached to the wall, since the mounting element is easily accessible after the control cabinet has been arranged on the wall.
- At least one passage opening is formed in each of the longitudinal legs of the mounting bracket. This embodiment also facilitates fastening, since the user can access holes that have already been made and they do not have to be drilled beforehand.
- the object is achieved by a control cabinet with a fastening element, comprising two profile rails which interlock in the suspended state, one rail being fastened to the wall and the other rail to the outside of the rear wall.
- the fastening holes of the control cabinet can be provided beforehand with a thread accessible from the outside of the rear wall, but this is not absolutely necessary since one of the two rails is fastened to the outside of the rear wall. and this attachment can be carried out without having to access the interior of the control cabinet.
- This fastening system is also particularly easy to install.
- the two profile rails can initially be fastened separately from one another on the wall or on the rear wall of the control cabinet.
- the rails are only pushed into each other after they have been fastened, so that no additional assembly is necessary. This enables the control cabinet to be attached by just one person.
- the profile rails are advantageously arranged parallel to a horizontal edge of the control cabinet.
- the horizontal alignment of the profile rail facilitates the vertical alignment of the control cabinet. It is thus possible to align the profile rail to be fastened to the wall with a spirit level, and in this way, in combination with the profile rail arranged parallel to the horizontal edge of the control cabinet, to achieve a straight alignment on the wall.
- This embodiment also greatly facilitates assembly, since the complete control cabinet does not have to be aligned.
- each profile rail can have a Z-shaped cross section.
- sufficient contact surfaces and engaging surfaces are provided to ensure a secure interlocking of the rails, as well as a sufficient fastening surface.
- the upper profile rail in the installed state can advantageously be fastened to the rear wall of the control cabinet. In this way it is possible to hang the control cabinet in the profile rail attached to the wall.
- a first leg of the profile rail can be fastened to the control cabinet and a second leg can extend downward from the first leg by a connecting web extending between the first leg and the second leg.
- This embodiment determines the orientation of the profile rail on the cabinet.
- the connecting web can be made somewhat wider than an end face of the legs.
- the selected distance between the first and second leg makes it possible for one leg of the lower profile rail to engage in the distance.
- a downward end face of the second leg in the installed state of the upper profile rail, can have at least one projection.
- the upwardly extending first leg of the lower profile rail can engage in the receiving region formed between the connecting web and the second leg of the upper profile rail in the suspended state.
- the at least one projection of the upper profile rail can advantageously engage in an exceptional opening formed in the connecting web of the lower profile rail.
- the interaction of the projection with the receiving opening serves to avoid lateral displacements.
- two projections and receiving openings can be formed. In practice, this number has proven to be sufficient to ensure a stable connection between the two profile rails.
- 1 is a three-dimensional view of a cabinet from the back
- FIG. 2 shows a section through the mounting hole
- 3 is a three-dimensional view of the switch cabinet shown in FIG. 1 with a mounting bracket attached to it;
- Fig. 5 shows the profile rails shown in Fig. 3 in lateral cross section
- Fig. 6 is a three-dimensional representation of a cabinet from the rear, with a profile rail has been attached.
- the control cabinet 1 shown in FIG. 1 has an approximately rectangular cross-section and comprises two side walls 2, a cover area 3, a floor area, not shown, and a rear wall 4.
- the front side of the control cabinet, which is not shown in FIG. 1, is usually locked with a door.
- the back wall consists of a sheet metal blank, and points in all four corner areas, i.e. each a predetermined distance from the corner, a mounting hole 5.
- a rivet nut 6 was inserted into each of these mounting holes 5 before the control cabinet was installed. This rivet nut 6 is in each case firmly connected to the fastening hole 5, so that it also remains in the fastening hole when the control cabinet is fastened to the wall by means of an assembly unit connected to the fastening hole.
- the rear wall of the cabinet 1 shown in Fig. 1 is shown again in section through a mounting hole 5.
- the mounting hole shown is a passage opening that extends through the entire rear wall 4.
- the rivet nut 6 it is also possible to insert the rivet nut 6 into a blind hole, ie a fastening opening 5 that does not extend through the entire rear wall 4.
- the rivet nut 6 extends both on the inside 7 and on the outside 8 of the rear wall a predetermined dimension beyond the respective side. If the rear wall 4 is placed somewhere in the course of processing, these protruding areas of the rivet nut 6 protect the outside or inside of the rear wall from damage, since they perform a spacer function here.
- control cabinet 1 To attach the control cabinet 1, it is attached using suitable mounting elements, e.g. a hanging bracket etc., which are attached to the back 4, attached to the wall or hung.
- suitable mounting elements e.g. a hanging bracket etc.
- rivet nuts 6 By providing rivet nuts 6 in the fastening hole in the rear wall, it is possible to fasten these assembly elements to the rear wall after the control cabinet has been fully equipped.
- FIG 3 shows a section of a control cabinet 1, a mounting bracket 9 having been connected to the rear side 4.
- the mounting bracket here comprises two longitudinal legs 10 and 11 arranged parallel to one another, which are connected to one another with a connecting leg 12.
- the connecting leg 12 extends at an angle of more than 90 ° between the longitudinal legs, so that they are offset from one another.
- the longitudinal leg 10 lies against the outside 8 of the rear wall 4, a passage opening 13 formed in the longitudinal leg 10 being aligned with the fastening hole 5 and the rivet nut 6.
- the longitudinal leg 10 is connected to the rear wall 4 by a screw engaging in the rivet nut 6.
- the longitudinal leg 10 preferably extends to the upper horizontal edge of the cabinet.
- the longitudinal leg 11 extends parallel at a certain distance from the outer wall 4.
- the longitudinal leg 11 also has through openings 14.
- control cabinet 1 If the control cabinet 1 is to be fastened to the wall, the control cabinet is brought up to the wall in such a way that the longitudinal leg 11 lies against the wall and can be fastened to the wall by means of screws.
- the number of necessary mounting elements and the necessary mounting holes depends on the size of the control cabinet to be attached. For smaller control cabinets, a number of four mounting elements and four mounting holes have proven their worth.
- a control cabinet with normal mounting holes can be used, but also a control cabinet with mounting holes that have been provided with an internal thread.
- the alternative fastening system comprises two profile rails that interlock when installed.
- the profile rails 15 and 16 are shown in Fig. 4 in a separate state and in Fig. 5 in cross section in the interlocking state.
- the two profile rails 15 and 16 have an identical structure in cross section, i.e. az shape. The same elements are aligned in the same way.
- the upper profile rail 15 comprises in detail a first leg 17 and a second leg 19 extending parallel to the first leg 17.
- the two legs 17 and 19 are connected to one another via a connecting web 20, which is each at an angle of less than 90 ° extends to the first or second leg 17, 19.
- the width of the connecting web 18 is chosen so that it is somewhat wider than each of the legs 17, 19.
- the outer side 20 of the first leg 17 facing away from the second leg 19 lies against the outer wall 8 of the control cabinet in the installed state, as shown in FIG. 5. On this, it can be connected by means of through openings 21 formed in the first leg 17 to the fastening holes provided on the rear of the control cabinet. As is also shown in FIG. 5, the profile rail 15 extends parallel to an upper horizontal edge of the control cabinet, wherein the upper profile rail 15 can extend over the entire horizontal width of the rear wall.
- Two projections 22 are formed on the end face of the second leg 19 facing downward, ie toward the floor, which extend downward as rectangular web elements.
- the structure and the alignment of the second profile rail 16 correspond to that already described with reference to FIG. 15. Therefore, the same elements are provided with the same reference numerals and each identified by an additional line.
- the second profile rail is fastened to the wall with the outside of the second leg 19 'facing away from the first leg 17'.
- the second profile rail also has passage openings 21 ', these passage openings being formed in the second leg.
- the position of the mounting holes 21 and 21 ' corresponds to each other.
- the end face of the second leg 19 does not have any projections here, but the connecting web 18 has rectangular recesses 24 which are similar in size and position to the projections 22.
- the profiled rails 15 and 16 are first connected separately to the rear side 4 of the control cabinet 1 or a wall.
- the second profile rail 16 is fastened in a horizontal position by means of a spirit level. Since the profile rail is very light, the alignment of the rail can be carried out without further problems.
- the second profile rail 15 is aligned on the upper horizontal edge of the rear wall 4, or the alignment is already predetermined by the mounting holes 5 provided and through openings 21. If the profile rails 15 and 16 are attached to the control cabinet 1 or the wall, the control cabinet 1 can simply be hooked into the profile rail 16 attached to the wall. For this purpose, the control cabinet must first be lifted over the profile rail 16, and is then lowered so that the two profile rails 15 and 16 interlock.
- the upper leg 17 'of the lower rail 16 is inserted into the gap formed between the lower leg 19 of the upper rail 15 and the outside 8 of the rear wall 4.
- the lower leg 19 of the upper rail 15 is inserted into a gap formed between the upper leg 17 'of the lower rail and the wall.
- the upper leg 17 'of the lower profile rail and the lower leg 19 of the upper profile rail 15 are consequently arranged parallel to one another.
- the projections 22 of the lower leg 19 of the upper rail 15 are inserted into the corresponding recesses 24 of the lower rail during this intervention. This prevents the cabinet from shifting sideways when it is hooked in.
- the end face of the lower leg 19 of the upper profile rail lies on the connecting web 18 'of the lower profile rail.
