Description

The present invention relates to a modular mounting system, such as a door communication system, comprising a carrier and at least a first functional unit and at least one second functional unit, each of which can be fixed in a recess of the carrier in a raster consisting of columns and rows, according to the preamble of Claim 1. Such a mounting system is for example off EP 0 878 988 A2 known.

In this case, the invention comprises at least one modular functional unit for such a modular mounting system, with a base body having at least one rectangular side boundary contour. Such a functional unit is an electrical functional unit, such as a call button, a loudspeaker or a camera. In addition, the invention comprises at least one non-electrical functional unit, namely a mailbox.

Known, modular door communication systems are assembled with the aid of frame systems with an integrated module carrier made of sheet metal or die-cast. The surfaces of such systems are formed by framed sub-surfaces of the functional units, which often consist of painted plastic, with usually only a small variation possibility of surface design.

A modular system and a functional unit of the type mentioned are, for example, from DE 31 08 056 C2 known. The document describes a door system with a common grid frame for receiving individual functional units, such as name badges, bell buttons, door speakers, etc., for which a flexible modular system is to be created by the grid arrangement. The grid frame is hingedly connected to a housing and has one or more, separated by webs, the same size grid openings to accommodate functional units with the same external dimensions.

The known functional unit has in its base body of the basic shape ago cuboidal, after mounting outside lying part with a rectangular side boundary contour, which, when it is inserted into the grid frame, the webs between the grid openings covered and seated thereon. In addition, the base body of the functional unit is stepped by a cuboid on the outer part of a parallelepipedal, after installation is located inside part, which is in the assembled state form-fitting enclosed by the respective grid opening. Also, the inner part has a rectangular Seitenbegrenzungskontur, but smaller than that of the outer part.

The housing can be fastened by means of fastening bolts to a flush-mounted housing. In addition to rubber seals, which lie between functional units and grid frame, a further seal and a mounting tolerance compensation are provided by the housing can be inserted into a sealing, balancing and Verblendrahmen and can be mounted together with this. Since the grid does not cover the entire system, additional veneer strips, such as the joint between the grid frame and the housing, are required.

It is also known, in particular to form metallic surfaces for modular mounting systems, by this one-piece, in particular metallic front panels or by inserting modules with metallic surfaces through openings cut into one-piece front panels.

In this regard is from the DE 199 18 892 A1 the design of the front of a door system known on the two, three or more functional elements or their covers are visible. In contrast to DE 31 08 056 C2 these elements do not have to be of a similar nature and may have different dimensions. For example, the presence of call buttons, mailboxes, a camera and a loudspeaker covered by a grille are described. The dimensioning of the front panel is based on a grid with arranged in vertical columns and horizontal rows square unit areas. The contours of the functional elements are in plan view square, rectangular or round, with all horizontal and all vertical components of the distances between the centers of the functional units in particular an integer multiple of the edge length of the unit surfaces should be, which is exemplarily set to 14 mm. Due to the grid division of the cover plate, any arrangement of the functional elements should give an aesthetically appealing image in plan view, whereby at least partial automation of the design of the arrangement should be made possible by using a computer system. For the described technical solution, it is essential that the dimensions of the contours of the functional elements can deviate up to and downwards from a measure determined from the unit edge length by up to 33.3 percent, for which a calculation formula is given which largely corresponds to the actual desired screening relativized again. A support structure for the functional modules is not described. It also remains unclear how the function modules are mounted.

The present invention has for its object to provide a modular mounting system and a modular functional unit of the respective type mentioned, which while maintaining the above-described Advantages of a modular system and with simple and reliable assembly and operability the above requirement profile better meet and in particular using known serially manufactured, differently standardized components ensure maximum utilization of the available visual or control surface.

This is achieved according to the invention for the modular mounting system by the characterizing features of claim 1. It is provided that the first functional unit and the second functional unit are dimensionally differently standardized, wherein the carrier is given a grid with square unit areas whose respective base has a pitch, according to which the respective length and the respective width of the recesses and the respective Center distance between the recesses are dimensioned as an integer product of the grid dimension, wherein the grid dimension is defined as a size by which both a characteristic length or width dimension, which is not less than a standardized minimum allowable dimension of a functional unit, as well as a standardized center distance the other functional unit is integer divisible, in which the grid dimension is 17.75 mm or 35.5 mm.

In other words, the pitch is defined as a common divisor of a characteristic length or width dimension not less than a standard minimum permissible dimension of the one functional unit and a standard permissible center pitch of the other functional unit, the pitch being multiplied by an integer results in both the length or width dimension of a functional unit, as well as a standardized center distance of the other functional unit.

This technical solution according to the invention is particularly important where as the first and second functional units electrical components, such as switches, buttons, cameras, etc., together with non-electrical units, such as in particular together with one or more mailboxes, may be provided in the same modular mounting system. On the one hand, this can in a modular mounting system according to the invention with simple and reliable assembly and operability and in a - with regard to the design and redesign of surface designs - easy to handle grid design, ie in particular without any deviations of the main dimensions length, width, center distance from the grid, a maximum utilization of the available visual or operating surface are guaranteed, and on the other hand, this allows one, in the sense of the above definition "frameless" structure of the system with lying on the design surface, each individually replaceable material and / or color surfaces for the individual functional units , On cover or front panels, as they are known from the prior art, can be dispensed with in this way with advantage.

The modular mounting system according to the invention allows, in particular if it is used as a communication system on doors, as communication panels or on freestanding mailboxes, the fulfillment of the above requirements, such as enabling a modular design, a flexible design of the arrangement of functional elements and the design an aesthetic appearance to which the technical solutions according to the DE 31 08 056 C2 and the DE 199 18 892 A1 already taken into account to varying degrees. Furthermore, it also ensures beyond a maximum ease of installation of the system, compliance with different standardized mounting distances for the functional elements and also standardized length and / or width dimensions of these elements and, in particular from the point of view of operability, an ergonomically optimal, but at the same time little surface-extensive design of the visible surface. Furthermore, there are extensive customization possibilities of the surface by special design design, in particular with a flush in plan view system of functional units together - a so-called "framelessness".

In particular, due to the compatibility with standardized parts, it is advantageously possible for a system according to the invention to use known series parts which can be used as modular functional units. In this case, such parts can also be used multiple times, whereby the total structural complexity and the number of installed components can be optimized.

For the functional unit it is provided that a grid with square unit areas is given for their rectangular side boundary contour whose respective base has a grid dimension, according to which the respective length and / or the respective width of the contour and / or in the presence of two or more functional units in a modular mounting system, the respective center distance between the functional units are dimensioned as an integral product of the grid dimension, wherein the grid dimension is defined as a size by which both a characteristic length or width dimension which is not smaller than a standardized minimum allowable dimension of a non-electrical functional unit, as well as a standardized center distance of an electrical functional unit is integer divisible. This means that the grid design according to the invention can be applied both to the carrier of the modular mounting system and to the modular functional units that can be mounted in the carrier.

In this case, advantageously dispensing with an additional front panel, an entire visible surface or at least a predominant portion of the visible surface of the modular mounting system according to the invention may be composed of sub-surfaces which consist exclusively of the respective surfaces of the modular functional units according to the invention and lie flush against each other. The surface segmentation according to the invention advantageously provides a high degree of customization of the surface. Thus, for each sub-surface, as needed, a different or uniform design with other sub-surfaces can be made, such as stainless steel overlays, Anodized aluminum plates, plastic, paint or, preferably self-adhesive, decorative films.

A minimum gap spacing in the range of approximately only 1 mm can advantageously be maintained between the functional units in the area of the visible front surface, which means that a gap width between two functional units taking into account any tolerance deviations in the range between 0.5 mm and 1, 5 mm, preferably between 0.8 mm and 1.2 mm.

In terms of a particularly clear grid design with not too small grid dimension is provided dasss this from a standardized characteristic length or width dimension of a non-electrical functional unit is formed, which is not smaller than a standard minimum permissible dimension, the grid with a whole Number multiplied by a permissible standardized, minimum center distance of the other, electrical, functional unit results.

For electrical functional units in Germany, the standard DIN 49075: 1989-10, which refers to "cover plates for installation devices for installation in device boxes with openings of 45 mm and with specified inserts (Part 1) or without specified inserts (Part 2); "refers. Hereafter, the standard combination distance for appliance boxes or equipment junction boxes 71 mm, with spacers can be used in multi-line installations with separate UP devices to separate the individual lines in multiple cover frame, which causes an increase in the permissible normalized combination distance to 91 mm. Combination distance is the center distance of the components - regardless of their length and width - understood. The standard minimum permissible center distance is thus 71 mm.

For mailboxes in Europe, the standard EN 13724: 2003-05, which has replaced the former German standard DIN 32617, and in addition to ergonomic requirements, eg. B. to accessibility, which, inter alia, house mailboxes, storage compartments and home distribution systems for deliveries and receivers are always easy to access and convenient to arrange, standard dimensions for, inter alia, characteristic length and width dimensions are fixed to the mailbox. These dimensional requirements consist in particular in that the slot width is at least suitable for letter formats C4 or should be at least 230 mm in size, or should be suitable for the format C4 transverse and at least 325 mm. The insertion slot height should be at least 30 + 5 mm. A removal lock located inside the mailbox should be at least 15 mm deep and extend over at least 80 percent of the slot width, with the distance to the mail piece being 5 mm and the stacking height of the mail piece to the removal lock 40 mm. Furthermore, according to the standard letterboxes must be installed so that the distance between the lower edge of the floor and the flap is not less than 500 mm or not more than 1700 mm.

On the basis of the grid design principle used in the context of the invention, reference is made to the standard dimensions of DIN 49075: 1989-10 and EN 13724: 2003-05. Here is to obtain the grid of the minimum slot slot height of a mailbox to EN 13724 standard, which should be 30 + 5 mm, assumed as standard minimum allowable length or width dimension of the functional unit, and determines the smallest possible measure multiplied by an integer the permissible standardized center distance of 71 mm according to DIN 49075 for the other functional unit results. Such a measure is a length of 35.5 mm (2 x 35.5 mm = 71.0 mm), which forms the length of the square base side in a grid with square unit areas, which is given for the carrier.

In other words, according to the invention, therefore, the grid is a divider, in particular the largest divider, of the two normalized magnitudes used to determine the grid dimension, from which both multiplication by an integer results in both the one and the other standardized size. The pitch 35.5 mm is not even integer.

The more general grid design according to the invention should be used if no standard minimum length or width dimension of one functional unit can be found which is a divisor of the allowable standardized center distance of the other functional unit.
However, it is optionally also possible to refine the grid scale with advantage, to divide the grid length described above by means of a division by two even finer.

In the case shown, dividing by 2 gives a pitch of 17.75 mm.

Further advantageous features of the invention are contained in the subclaims and the following description.

In the figures of the drawing, the same or corresponding parts are always provided with the same reference numerals, so that they are usually described only once in each case.

As it turned out first Fig. 1 and 2 1, a modular mounting system 1 according to the invention comprises a carrier 2 with four recesses AE for at least one first functional unit 3, which is an electrical installation device of the type described in FIGS Fig. 6 and 7 show, and for the the standard dimension is a minimum center distance MA _min = 71 mm specified in DIN 49075: 1989-10.

Furthermore, the carrier 2 has five recesses AB for at least one second functional unit 4, which is a mailbox /. This one is in Fig. 1 shown without flap 5, but such in the embodiments according to Fig. 4 and 5 shown, however, do not show the covered by the flap recesses AB. For such a mailbox 4, a minimum insertion slot height specified in EN 13724: 2003-05 is EW _min = 30 + 5 mm.

The carrier 2, which can also be referred to as a system carrier, is made of metal, in particular from the perspective of a desired high stability, preferably made of stainless steel sheet. The recesses AE, AB can be generated therein, for example by punching or preferably with the highest precision by laser cutting.

The functional units 3, 4 can be mounted on the carrier 2, wherein they are held at least positively in the recesses AE, AB by an installation made by insertion into the recesses AE, AB of the carrier 2 assembly. How such an assembly of the functional units 3, 4 can be realized, shows Fig. 7 exemplary for a first functional unit 3.

The functional units 3, 4, which are dimensionally differently standardized with respect to their permissible mounting distances MA to further functional units and with respect to at least one characteristic minimum length and / or width dimension EW, are in the recesses AE, AB of the carrier 2 in a vertical column S and horizontal rows R arranged grid RA, like this one in Fig. 2 and 3 is shown, definable.

How through Fig. 2 and 3 is illustrated, is for the carrier 2, a grid RA with square unit areas QE1, QE2 whose respective base has a grid RM1, RM2, according to which the respective length LE, LB and the respective width BE, BB of the recesses AE, AB and the respective center distance MA between the recesses AE are dimensioned as an integral product of the grid dimension RM1, RM2.

The grid size RM2, which results from the standardized characteristic length or width dimension EW _{min of} the mailbox 4 and the standardized minimum center distance AM _{min of} the electrical installation device 3, is subdivided by division by an integer n = 2 into an even finer grid size RM1 ,

Each grid RM1, RM2 is thus a common divisor, in particular a largest common divisor, the characteristic length or width dimension "insertion slot height EW", which is not smaller than the standardized minimum allowable dimension EW _min = 30 + 5mm of the mailbox 4 as a second functional unit 4, and the standardized minimum permissible center distance MA _min = 71 mm of the electrical installation device 3 as the first functional unit 3.

In this case, the grid RM1, RM2 in each case with an integer number (n = 2 for RM2, n = 4 for RM1) multiplied both the standardized minimum center distance AM _min = 71 mm, and the characteristic length or width dimension "insertion slot height EW = 35 , 5 mm "(n = 1 for RM2, n = 2 for RM1). With regard to the corresponding numerical values, this is particularly apparent Fig. 3 which makes this clear.

In addition, the characteristic length or width dimension EW of the mailbox with an integer n = 1 or 2 or 3 ..., in particular with an integer n, which is greater than or equal to 2 - and in the present case with 2 for RM2 = 35.5 mm and 4 for RM1 = 17.75 mm - multiplies the permissible minimum standardized center distance MA _min = 71 mm of the first electrical functional unit 3.

1. 1. Alle Längen LE und Breiten BE der Ausnehmungen AE für die ersten Funktionseinheiten 3 sind als ganzzahlige Produkte des feineren Rastermaßes RM1, aber auch des gröberen Rastermaßes RM2 dimensioniert. So beträgt die Länge LE und Breite BE der Ausnehmungen AE für die elektrischen Installationseinheiten 3 jeweils 71 mm, also das Vierfache des feineren Rastermaßes RM1 bzw. das Doppelte des gröberen Rastermaßes RM2.
2. 2. Alle Längen LB und Breiten BB der Ausnehmungen AB für die zweiten Funktionseinheiten 4 sind als ganzzahlige Produkte des feineren Rastermaßes RM1, aber auch des gröberen Rastermaßes RM2 dimensioniert.
   So beträgt die Breite BB der Ausnehmungen AB für die nichtelektrischen Installationseinheiten 4, welche insbesondere eine Einschubweite 2 * EW für einen Briefkasten darstellt, 71 mm, also ebenfalls jeweils das Vierfache des feineren Rastermaßes RM1 bzw. das Doppelte des gröberen Rastermaßes RM2. Eine genormte Einwurfschlitzhöhe EW_min von 30+5 mm kann somit am Briefkasten eingehalten werden. Die Ausnehmung AB, welche in Fig. 1 und 2 rechts neben den Ausnehmungen AE für die elektrischen Installationseinheiten 3 angeordnet ist, fluchtet daher mit den Letzteren.
   Die Länge LB der Ausnehmungen AB für die nichtelektrischen Installationseinheiten 4 beträgt 390,5 mm, also jeweils das 22-fache des feineren Rastermaßes RM1 bzw. das 11-fache des gröberen Rastermaßes RM2. Die Breiten BB sind somit für den Einwurf von Briefsendungen im Format C4 quer geeignet, wobei gemäß Norm die Schlitzbreite mindestens 325 mm betragen soll. Die vertikalen Seitenkanten der beiden Ausnehmungen AB für die Briefkästen 4, die unter den Ausnehmungen AE für die elektrischen Funktionseinheiten 3 angeordnet sind, fluchten dabei nicht nur miteinander, sondern auch mit der ersten und der letzten vertikalen Seitenkante der darüber angeordneten Ausnehmungen AE für die elektrischen Funktionseinheiten 3. Dadurch ist u. a. eine Voraussetzung für eine ästhetisch ansprechende Oberflächengestaltung des erfindungsgemäßen modularen Montagesystems gegeben.
3. 3. Alle Mittenabstände AM zwischen den Ausnehmungen 3 für die elektrischen Installationseinheiten 3 sind als ganzzahliges Produkt des feineren Rastermaßes RM1, aber auch des gröberen Rastermaßes RM2 dimensioniert. Sie betragen jeweils 106,5 mm, also das Sechsfache des feineren Rastermaßes RM1 bzw. das Dreifache des gröberen Rastermaßes RM2 und sind damit 1,5 mal so groß wie das normgemäß minimal zulässige Abstandsmaß AM_min von 71 mm.
4. 4. Alle horizontal verlaufenden Stege 6a und alle vertikal verlaufenden Stege 6b, die die sich gemäß Fig. 2 in dem Träger 2 zwischen den Ausnehmungen AE, AB für die Funktionseinheiten 3, 4 befinden, weisen jeweils eine Stegbreite SB auf, die nach dem für den Träger 2 vorgegebenen Raster RA bemessen sind, indem die Stegbreite SB jeweils ein Maß von 35,5 mm aufweist, das ein ganzzahliges Produkt - mit den Faktoren n = 1 für RM2 bzw. n = 2 für RM1 - des jeweiligen Rastermaßes RM1, RM2 der quadratischen Einheitsflächen QE1, QE2 des Trägers 2 ist. Auch dies trägt zu einem ästhetisch ansprechenden Erscheinungsbild bei.
   Im Hinblick auf die Stege 6a, 6b besteht allerdings insofern zwischen der in Fig. 1 und 2 dargestellten Ausführung ein Unterschied, als das erfindungsgemäße modulare Montagesystem 1 gemäß Fig. 1 mit Vorteil einen segmentierten Träger 2 aufweist. Dadurch sind nicht alle horizontal verlaufenden Stege 6a und alle vertikal verlaufenden Stege 6b zwischen den Ausnehmungen AE, AB für die Funktionseinheiten 3, 4 mit der gleichen Stegbreite SB ausgeführt.
   Gemäß der Ausführung in Fig. 1 ist für die ersten Funktionseinheiten 3 ein erstes Trägerteil 2a vorgesehen, das mit einem zweiten Trägerteil 2b für die zweiten Funktionseinheiten 4 modular verbindbar ist. Dadurch, dass der Träger 2 aus zwei oder mehr modular miteinander verbindbaren Trägerteilen 2a, 2b besteht, die jeweils den ersten Funktionseinheiten 3 oder den zweiten Funktionseinheiten 4 zugeordnet sind, ist im Sinne des eingangs erwähnten Baukastenprinzips eine höhere Flexibilität des erfindungsgemäßen Systems 1 gegeben, weil die einzelnen Trägerteile 2a, 2b auch unabhängig voneinander montierbar sind. Dies zeigen beispielsweise Fig. 6 und 7, wonach nur das Trägerteil 2a für die elektrischen Funktionseinheiten 3 bei einer Montage verwendet wird und dort den gesamten Träger 2 bildet. Zur gegenseitigen Verbindung der Teile 2a, 2b bei einer Montagesituation wie gemäß Fig. 1 kann eine spezielle, leicht montierfähige Verschluss- bzw. Verbindungstechnik vorgesehen sein.
5. 5. Alle horizontalen verlaufenden Ränder 7a und alle vertikal verlaufenden Ränder 7b, die im Träger 2 außen an den Ausnehmungen AE, AB für die Funktionseinheiten 3, 4 angrenzen, weisen jeweils eine Randbreite RB auf, die nach dem für den Träger 2 vorgegebenen Raster RA bemessen sind, indem die Randbreite RB im Sinne einer platzsparenden Anordnung nur ein Maß von 17,75 aufweist, das ein ganzzahliges (n = 1) Produkt des kleineren Rastermaßes RM1 = 17,75 der quadratischen Einheitsflächen QE1 des Trägers 2 ist. Selbstverständlich könnten bedarfsweise die Ränder 7a, 7b auch mit der doppelten Größe dieses Maßes, also mit dem gröberen Rastermaß RM2 = 35,5 mm ausgeführt werden.
   Aus Fig. 1 sowie 4 bis 7 ist zu entnehmen, dass an den Rändern 7a, 7b zweckmäßigerweise Versteifungen 8 vorgesehen sein können, die insbesondere durch rechtwinklig von der Frontseite nach hinten weggebogene Trägerstreifen gebildet sind.
6. 6. Der Träger 2 selbst weist eine Trägerlänge TL und/oder eine Trägerbreite TB auf, die jeweils nach dem für den Träger 2 vorgegebenen Raster bemessen ist, indem die Trägerlänge TL und/oder die Trägerbreite TB jeweils ein Maß aufweisen, das ein ganzzahliges Produkt des erfindungsgemäßen Rastermaßes (48 x RM1 bzw. 24 x RM2) der quadratischen Einheitsflächen QE1, QE2 des Trägers 2 ist.

Fig. 2 in particular, the projection of the inventive grid RA with the smaller unit areas QE1 on the in Fig. 1 illustrated carrier 2 of the modular mounting system 1 according to the invention, illustrates in detail by way of example the following:

1. 1. All lengths LE and widths BE of the recesses AE for the first functional units 3 are dimensioned as integer products of the finer pitch RM1, but also of the coarser pitch RM2. Thus, the length LE and width BE of the recesses AE for the electrical installation units 3 are each 71 mm, ie four times the finer grid size RM1 or twice the coarser grid size RM2.
2. 2. All lengths LB and widths BB of the recesses AB for the second functional units 4 are dimensioned as integer products of the finer pitch RM1, but also of the coarser pitch RM2.
   Thus, the width BB of the recesses AB for the non-electrical installation units 4, which represents in particular an insertion width 2 * EW for a mailbox, 71 mm, ie also each four times the finer grid RM1 or twice the coarser grid RM2. A standardized insertion slot height EW _min of 30 + 5 mm can thus be maintained at the mailbox. The recess AB, which in Fig. 1 and 2 is arranged to the right of the recesses AE for the electrical installation units 3, therefore aligned with the latter.
   The length LB of the recesses AB for the non-electrical installation units 4 is 390.5 mm, so each 22 times the finer pitch RM1 or 11 times the coarser pitch RM2. The widths BB are thus for the Insertion of letter mail in C4 format suitable for cross, whereby according to standard the slit width should be at least 325 mm. The vertical side edges of the two recesses AB for the mailboxes 4, which are arranged under the recesses AE for the electrical functional units 3, are aligned not only with each other, but also with the first and the last vertical side edge of the overlying recesses AE for the electrical functional units 3. As a result, inter alia, a requirement for an aesthetically pleasing surface design of the modular mounting system according to the invention is given.
3. 3. All center distances AM between the recesses 3 for the electrical installation units 3 are dimensioned as an integral product of the finer pitch RM1, but also the coarser pitch RM2. They are each 106.5 mm, which is six times the finer grid size RM1 or three times the coarser grid size RM2 and are thus 1.5 times as large as the standard minimum allowable distance AM _min of 71 mm.
4. 4. All horizontally extending webs 6a and all vertically extending webs 6b, the in accordance with Fig. 2 in the carrier 2 between the recesses AE, AB for the functional units 3, 4, each have a web width SB, which are dimensioned according to the predetermined for the carrier 2 grid RA by the web width SB each have a dimension of 35.5 mm which is an integer product - with the factors n = 1 for RM2 and n = 2 for RM1 - of the respective grid dimension RM1, RM2 of the square unit areas QE1, QE2 of the carrier 2. This also contributes to an aesthetically pleasing appearance.
   With regard to the webs 6a, 6b, however, exists between the in Fig. 1 and 2 illustrated embodiment, a difference, as the inventive modular mounting system 1 according to Fig. 1 having a segmented carrier 2 with advantage. As a result, not all horizontally extending webs 6a and all vertically extending webs 6b between the recesses AE, AB are executed for the functional units 3, 4 with the same web width SB.
   According to the execution in Fig. 1 For the first functional units 3, a first carrier part 2a is provided, which is modularly connectable to a second carrier part 2b for the second functional units 4. Characterized in that the carrier 2 consists of two or more modularly connectable support members 2a, 2b, which are each associated with the first functional units 3 or the second functional units 4, in the sense of the above-mentioned modular principle, a higher flexibility of the system 1 according to the invention given because the individual carrier parts 2a, 2b can also be mounted independently of one another. This is shown, for example Fig. 6 and 7 according to which only the support part 2a for the electrical functional units 3 is used during assembly and forms the entire support 2 there. For the mutual connection of the parts 2a, 2b in a mounting situation as in accordance with Fig. 1 may be provided a special, easily mountable closure or connection technology.
5. 5. All horizontal edges 7a and all vertical edges 7b, which adjoin the outside of the recesses AE, AB for the functional units 3, 4 in the carrier 2, each have an edge width RB, which after the given for the carrier 2 grid RA are dimensioned by the edge width RB in terms of a space-saving arrangement has only a measure of 17.75, which is an integer (n = 1) product of the smaller pitch RM1 = 17.75 of the square unit areas QE1 of the carrier 2. Of course, if necessary, the edges 7a, 7b could also be designed with twice the size of this dimension, ie with the coarser grid size RM2 = 35.5 mm.
   Out Fig. 1 As well as FIGS. 4 to 7, it can be seen that stiffeners 8 can expediently be provided at the edges 7a, 7b, which stiffeners are formed in particular by carrier strips bent away at right angles from the front side.
6. 6. The carrier 2 itself has a carrier length TL and / or a carrier width TB, which is in each case dimensioned according to the grid predetermined for the carrier 2, in that the carrier length TL and / or the carrier width TB each have a dimension which is an integral product of the grid dimension according to the invention (48 x RM1 or 24 x RM2) of the square unit areas QE1, QE2 of the carrier 2.

The modular system 1 according to the invention can be used with advantage in a variety of installation types and types, such as flush mounting, surface mounting, wall installation, communication pillars, freestanding mailboxes, communication panels, door side installation and on-site front panels. Not all of the feature combinations described above under points 1 to 6 need to be implemented simultaneously, but at least only the features according to claim 1.

In Fig. 4 an embodiment is shown in which the inventive system 1 comprises a flush mounted with two mailboxes 4 housing 9, which allows for the three therein to be provided electrical functional units 3 a recessed, protected mounting, which is especially freestanding mailboxes, communication panels and door side installation is beneficial. In this case - as shown - optionally an integrated rain roof 10 may be provided, which proves to be advantageous in particular by the possibility of installing a system lighting or indirect object lighting in freestanding housing systems. In addition to the already mentioned electrical functional units 3, which have a square plan and have a center distance MA of six times smaller pitch, and the mailboxes 4 are provided as further electrical functional units bell button 3a for inserting or sticking name badges and bell button 3b for engraving names, the are also sized according to the invention RA raster.

Out Fig. 5 showing a third embodiment of a modular mounting system 1 according to the invention, which - even without enclosing the system front Housing 9 - for a frameless installation in flush, surface, wall installation, communication columns or as a field-side faceplate, in particular results in an advantageously possible by the invention surface design. In particular, it is clear from the representation that in a modular mounting system 1 according to the invention its entire visible surface SF or at least a predominant portion of the visible surface SF can be composed of partial surfaces TF consisting exclusively of surfaces TF of the existing modular functional units 4, 11. As functional units 4, 11 in this case two letterbox modules 4 and four decorative modules 11 are provided. The decoration modules 11 can thereby - which is not visible in the drawing representation - be designed on the back side in such a way that they are adapted to fit into the recesses AB provided for the mailboxes 4 and can be held therein. They can thus have a basic body G of the type described below for the electrical functional units 3.

As the plan view of the viewing surface SF shows, all the respective visible lengths LP and widths BP of the functional units 4, 11, which are unspecified in the figure, are dimensioned as an integral product of at least the grid dimension RM1, these dimensions LP, BP being a tolerance measure for formation a gap 12 between two functional units 4/4, 5/5, 4/5 is reduced. The tolerance dimension is advantageously dimensioned such that the gaps 12 each have only a gap width SW of about 1 mm, more precisely in the range between 0.5 mm and 1.5 mm, preferably between 0.8 mm and 1.2 mm ,

Fig. 6 shows from a perspective from a wall side forth, a fourth, in particular for flush mounting (flush mounting) suitable embodiment of a modular mounting system according to the invention 1. In addition to a frame 2 and four inventively designed, modular, standardized standard functional units 3 according to the invention a UP Box 13 and mounted between masonry and functional modules 3 wall seal 14 is provided. The various components 13, 2, 14, 3 of the system 1 are shown in an assembly order and location corresponding exploded view.

The electrical functional units 3 according to the invention - and this show both Fig. 6 , as well as Fig. 7 - Have a base G, which has at least one rectangular side boundary contour K1, K2, K3. As can be seen from the drawing, however, the basic body in the illustrated exemplary embodiment has three rectangular side boundary contours K1, K2, K3.

This is due to the fact that the main body G is formed in three stages. It comprises an inner first part 30 which is cuboidal in shape from the basic shape and which, in particular, can be fitted into the recesses AE of the carrier 2 of the modular mounting system 1 in a shape-adapted manner, as is the case Fig. 7 shows, and has a first rectangular side boundary contour K1.

Furthermore, the main body G comprises a parallelepiped-shaped central second part 31, which has a second, larger rectangular side boundary contour K2 than the inner part and is intended, in the assembled state, for webs 6a, 6b of the carrier 2 between the recesses AE, AB and / or edges 7a, 7b of the carrier 2 at the recesses AE, AB completely or at least partially cover, which also by Fig. 7 is illustrated.

Finally, the main body G comprises a basic shape also cuboidal, but in particular thinner than the second part 31 executed, third part 32, which has a third, larger rectangular side boundary contour K3 than the second part 30 and in the assembled state in particular a plaster cover and serves in the assembled state the in Fig. 6 illustrated UP box 13 can project beyond the edge.

On the main body G may preferably be a cover 15, such as a plate or foil, be attached, which is in particular made of a stainless steel support, an anodized aluminum plate, plastic, paint or from a, in particular self-adhesive, decorative film. The respective length LP and width BP of the cover 15 of the functional unit 3, the design of which determines the appearance of the visible surface SF, is in particular congruent with the underlying largest contour K3 of the main body G. The presence of the cover 15 is advantageously a Separation of the design of the user interfaces of the functional units 3 possible. This can be achieved with the same functional module 3 a large variety of surfaces.

In particular, the respective length and the respective width of all contours K1, K2, K3 of the parts 30, 31, 32 of the base body G and particularly preferably the length LP and width BP of the cover 15 may be preferred - as well as the respective center distances AM of the parts 30, 31, 32 of the main body G to further functional units 3, 3a, 3b, 4, 11 be dimensioned as an integer product of the grid RM1, RM2. A preferred measure of the length LP and width BP and the center-to-center distance MA of standard functional units 3 formed with a square surface TF are six system rasters RA and 106.5 mm, respectively.

In the context of the invention, in particular the respective center distance MA between the recesses AE, AB is particularly important, which is in particular identical to the center distance of the mounted functional units 3, 3a, 3b, 4, 11. In a modular mounting system 1 according to the invention, the respective length LE, LB and the respective width BE, BB of the recess AE, AB and preferably also the respective length LP and width BP of the cover 15 of the respective functional unit 3, 3a, 3b, 4, 11th or whose contour K3 lying in the visible surface SF is dimensioned as an integral product of the grid dimension RM1, RM2. As far as the design of the basic body G is concerned, under certain circumstances the outer part 32 could also be omitted from the basic shape.

For the modular system according to the invention is also given the opportunity to build one-piece surfaces, d. H. a design front (visible surface SF), which is supported by a plurality of functional units 3 in the system grid RA of the one-piece front.

Furthermore, the skilled person, as has already been made clear by the rain roof 10 described by way of example, can provide additional technical measures by means of which the invention is expediently designed. Again, it may be advantageous to make the dimensions of the additional parts according to the grid according to the invention.

For the functional units 3, 3a, 3b, 4, 11 can - as in particular in Fig. 1 . 4 . 6 and 7 for the electrical functional units 3 is shown - an encoding, for example, by appropriate free cuts 16 in the system carrier 2, be provided that ensure a positionally correct and functionally correct arrangement and a security against rotation of the functional modules for the mounting system 1 according to the invention.
