Equipment cabinet

The invention relates to an equipment cabinet in which, in addition to a receiving device for horizontally arranged fittings, a shunting space for cable routing is provided between this and one or both side walls of the equipment cabinet (each).

Equipment cabinets (this term also includes equipment housings and equipment racks) are usually used to obtain a spatial grouping of individual components for facilities that consist of a large number of electrical or electronic devices or individual components, where this is advantageous for functional, organizational or other reasons.

For the above-mentioned purpose, receptacles that can be inserted into such equipment cabinets in the form of suitably constructed frames or the like are provided, which are fastened to the equipment cabinet after being placed there and are in turn provided with fittings for accommodating individual components or individual elements.

Usually, the mounts or mounting devices are designed so that they are arranged horizontally. The wiring of the individual components that are accommodated in the built-in components is carried out before they are installed in the relevant equipment cabinet. However, after installation, the large number of cables present in the cabinet must be distributed or installed in a suitable manner, with the cables often being located or routed to the left or both sides or right of the built-in frames or the built-in components. For this purpose, it is known to provide a free space within the equipment cabinets either on both sides of the mount for the horizontal built-in components, a

so-called "shunting space" to accommodate such cable strands or to install the receiving device directly next to one of the two side walls of the equipment cabinet, whereby the shunting space is only on the other side of the receiving device between this and the other side of the cabinet. In the former case, this is referred to as a so-called "symmetrical" reduction, in the latter case as an "asymmetrical" reduction of the cabinet width, whereby it is usual to partially or completely cover the shunting space on the front of the cabinet with a (preferably screw-on) front panel or cover in order to prevent both looking into the tangle of cables and unwanted access to the cabinet.

Such equipment cabinets with a shunting room, which is usually used as a cable shunting room, are particularly common in the field of computer networking, where a particularly large number of cables have to be fed into and out of a cabinet, which is why wider cabinets are often used here, in which the free space on the left or right or both sides allows the cables to be easily fed to the individual components and connections. The disadvantage of such cabinets, however, is their larger base width in relation to their usable height.

In order to reduce the interior width of the wider cabinets with maneuvering space to the generally used 19-inch size (482.6 mm) required for installing the device racks, a 19" retaining profile is attached to an outer wall of the cabinet on one side and the other is mounted using a reducing rail (the width of which depends on the base width of the cabinet). For a two-sided (symmetrical) reduction, two 19" retaining profiles are each attached and mounted using suitable reducing rails. Different versions of retaining profiles and reducing rails are available for both options, although it is also possible, for example, to mount retaining profiles directly on cross members without using reducing rails.

The standardized design of such rack cabinets is specified, for example, in DIN 41 494 or IEC 297, whereby the so-called "19-inch design" has generally prevailed for the modular design of the electronic devices, inserts and subracks used, which is based on the width of the front panels for devices, inserts and

Subracks according to IEC publication 297 or the US standard ANSI C 83.9 and concerns the modular construction of electronic devices and systems.

Equipment cabinets of the type mentioned above with a shunting space that is symmetrical or asymmetrical to the receiving device are common and are shown and described, for example, in the applicant's brochure "roger modul-system 19", "Electronics cabinet series 330/340, series 440", on page 10 or so.

However, these known equipment cabinets with shunting space have the fundamental disadvantage that they provide less net installation space in relation to the floor space used, compared to cabinets without shunting space, where it is no longer possible to lead the cable harnesses out from the side within the cabinet.

Based on this, the invention aims to propose an equipment cabinet of the type mentioned at the beginning with a maneuvering space, which provides the user with an increased net installation space with the same cabinet floor area.

According to the invention, this is achieved in an equipment cabinet of the type mentioned at the beginning by providing a receptacle for vertically arranged components in each shunting room, with an intermediate space being formed between these components and the receptacle for horizontally arranged components for the passage of cables or cable harnesses.

The inventive measure of arranging a receptacle (in the sense of the terminology according to DIN 41 494) for an additional vertical installation of built-in components next to the existing horizontal installation of built-in components in such a way that there is a suitable distance between the horizontal and vertical built-in components for the passage of cables, opens up the possibility of creating additional installation options for corresponding individual components that go beyond the normal specified usable height of the equipment cabinet, whereby it is in principle irrelevant whether an asymmetrical shunting room or two symmetrical shunting rooms are provided in the individual case. The space in conventional shunting rooms is largely unused because it is not even occupied by the cable ducts.

can thus be advantageously put to further use by accommodating individual components without affecting the possibility of routing cables in the shunting room over its entire height.

If we consider the case where the reduction of a standard 800 mm wide equipment cabinet is usually 200 mm (regardless of whether it is arranged symmetrically or asymmetrically), the additional installation space gained by the invention amounts to at least 12 HE additional space for a cabinet with a usable height of 43 height units (HE) (namely three installation positions of 4.5 HE each) and at least 16 HE additional space for a cabinet with a usable height of 45 HE (i.e. four installation positions of 4.5 HE each), where 1 HE = 44.45 mm. This means that a total gain of 27.90% or 35.5% net installation space can be achieved with the same cabinet floor area compared to the generic equipment cabinets. The space gain figures given refer to whole U steps, whereby the installation of non-standard components with 1/2 U stepped housings or components results in an even greater net space gain.

The invention also has the advantage that the vertically installed components can be installed at the same height as the installed modules in their standard installation position specified by the receiving device for the horizontally arranged components, which allows the further advantage of a logical assignment and particularly short cable routes to be achieved.

The invention also has the advantage that it can be used to combine systems that comply with different standards in the corresponding equipment cabinet, such as a 19" horizontal installation and a metric vertical installation or vice versa, which offers great advantages for users and manufacturers, especially in view of the upcoming medium-term transition phase from the 19" system to the metric system.

The invention makes it possible for every shunting space within the cabinet to be kept free for the purpose of routing cables only to the extent that this is really necessary, while the space not required for this purpose can be used for the vertical installation of components that are installed in such a way that they lie outside the passage space required for the cable routing. This enables almost optimal use of the available space as

Installation space is guaranteed, while at the same time the necessary cable routing space is still available. The distance between the horizontal and vertical installations to create the space through which the cables can be routed is advantageously at least 6 mm, but preferably 8 mm and particularly preferably 10 mm. However, larger distances can also be advantageous in certain applications.

It is also advantageous in certain applications if the vertically arranged components extend over an installation depth that is smaller than the installation depth of the horizontally arranged components, whereby additional free space for cables and/or cable harnesses is created over the entire height of the equipment cabinet between the rear wall of the cabinet and the slide-in end of the vertical components.

An advantageous embodiment of the equipment cabinet according to the invention also consists in that each receptacle for vertically arranged fittings is manufactured as a support frame, which in turn is preferably designed in the form of a box frame. The support frame can also advantageously consist of two individual frames located on the front and rear of the equipment cabinet, which are connected to one another in a suitable manner, whereby the connection can be formed via suitable depth struts on only one side or on both sides of these individual frames.

An advantageous embodiment of the invention also consists in the fact that the support frame is provided with cross braces and/or depth braces.

Advantageously, in the equipment cabinet according to the invention, each installation is assigned a front frame that is detachably attached to the support frame according to its position, which can be combined particularly favorably with a fixed intermediate shelf that is hooked into its opening at one end.

In the equipment cabinet according to the invention, the individual components can be designed in different forms, preferably as fixed intermediate floors and/or as components that can be extended on telescopic rails, which results in great flexibility in use.

A further preferred embodiment of the invention is that the holder for vertically arranged fittings simultaneously forms a support beam for the holder for horizontally arranged fittings and thus represents a so-called "integrated" reducing holding profile, which in one component forms both the reduction and the function of the holding profile for the holder of the horizontally arranged fittings. The invention proves to be particularly advantageous in the sense of a design of such an integrated reducing holding profile.

Preferably, the section of the holder for vertical components forming the support beam in such an integrated reducing support profile is provided with vertically arranged grid holes (preferably in rows).

It is further preferred if, in the equipment cabinet according to the invention, the vertically arranged fittings are provided with grid holes in the horizontal direction, preferably arranged in rows, which also applies equally as a preferred design for cross braces and/or depth braces and/or front frames provided in the equipment cabinet according to the invention.

It is also particularly advantageous if each receptacle for the vertically arranged components is designed as a self-contained installation unit, which greatly facilitates assembly and disassembly.

Another, also preferred embodiment of the equipment cabinet according to the invention consists in that the front and/or rear of the support frame is designed as a one-piece part, preferably made of sheet metal, which not only results in a good optical image, but also enables particularly quick installation.

The inventive design of an equipment cabinet is equally suitable for front as well as rear mounting of the components.

The invention also relates to a holder for vertically arranged components that can be installed in a shunting space of an equipment cabinet, whereby this holder is designed in such a way that after its installation in the equipment cabinet between these components and horizontally arranged components of a

a gap or intermediate space for the passage of cables is formed in the receiving device for horizontal fittings, whereby this receiving device for vertically arranged fittings can have all the configurations already specified above for such receiving devices.

The invention is explained in more detail below using the drawing as an example. They show:

Fig. 5 is a schematic view of the cabinet from Fig. 3, but without horizontal installations in the middle cabinet area;

Fig. 6 another form of support for vertical fittings in the form of a supporting part with a front frame that can be screwed onto the front, and

Fig. 7 shows yet another form of support for vertical fittings with a supporting frame in which telescopically extendable fittings are arranged.

In the figures, identical or similar parts are provided with the same reference symbols.

Figures 1 and 3 show, in a purely schematic representation, the front views of two equipment cabinets 1, each of which basically consists of a rack-like frame, which has side walls 2 and 3, a base 4, a cover plate 5 and

-8th -

if necessary also a rear end plate 6 (cf. Fig. 2 as only a basic sectional view along H-II from Fig. 1).

In the representations of Figures 1 to 3, the equipment cabinets 1 have the same height and the same base area, with a mounting device (not shown in detail) for horizontally arranged components 7, which can be, for example, module carriers, inserts (racks) or shelves, being mounted in each equipment cabinet 1. The representation of the components 7 in the figures is purely schematic and only serves the purpose of clarifying the assignment of the individual components to one another within the cabinet 1.

In the equipment cabinet 1 according to Fig. 1, the receiving device for the horizontally arranged built-in components 7 is mounted directly next to one side wall 2, so that between the inner sides of the built-in components 7 in the equipment cabinet 1 and the opposite side wall 3 of the equipment cabinet 1, a free space remains, which is available as a shunting space R for cables 11 (Fig. 2), which are in the form of single cables, multiple cables or even cable harnesses, in order to carry out the necessary sub-distribution for the cable supply and discharge within the equipment cabinet 1 to the individual built-in components 7 in their different height arrangements.

The routing of these cables 11 within the shunting area R can take place either in specially provided guide rails (not shown), but in many cases the cables 11 or cable harnesses are also routed loosely or tied together in groups.

In the equipment cabinet 1 according to Fig. 3, the central arrangement of the receiving device for the horizontally arranged built-in components 7 on both sides of the same between their sides and the associated side wall 2 or 3 of the equipment cabinet 1 creates two shunting spaces R that are only half as wide as in the case of the arrangement according to Fig. 1, which is why the arrangement in Fig. 1 is referred to as an asymmetrical arrangement of the shunting spaces R and the arrangement in Fig. 2 as a symmetrical arrangement ("symmetrical" or "asymmetrical" reduction).

The installation of the components 7 can be carried out from the front or from the back of the equipment cabinet 1 or on the front or from the back of the equipment cabinet 1. In the illustration in Fig. 2, only purely

- 9-

schematically, vertically mounted in the housing of the equipment cabinet 1 on the side of the side wall 2, holding profiles 8 are located directly next to it, which serve as lateral holding profiles for the horizontal fittings 7 to be mounted and can be connected to one another in a suitable manner, which will be discussed further below in connection with the description of the following figures, both independently of one another and via suitable depth struts (not shown in Figs. 1 to 3). In this case, the holding profiles 8 can be attached directly to the adjacent side wall 2, so that stiffening in the depth direction can be omitted on this side.

As Fig. 2 shows in a basic sectional view, the horizontal built-in components 7 do not extend in the depth direction of the cabinet 1 from the front of the cabinet to its rear cover 6, but end at a certain distance in front of it. This applies to many built-in components 7, but is not mandatory, i.e.

In certain applications, built-in components 7 could also be used which run across the entire depth of the equipment cabinet 1.

In the shunting room R, a receptacle 9 for vertically arranged fittings 10 is provided, generally provided with the reference number 9, in such a way that, as can be seen from the basic sectional view in Fig. 2, there is a distance A between the mutually facing sides of the horizontally arranged fittings 7 and the vertically arranged fittings 10. This creates a free space between these mutually facing sides of the fittings 7 and 10, extending over the entire internal height of the equipment cabinet 1, through which a large number of cables 11 in the form of single cable guides, multiple cable guides or cable harnesses can be led up for sub-distribution to or for distribution between the individual installation levels. In addition, if desired, further cables could also be led through the rear free space between the fittings 10 and the rear end plate 6, which are indicated in dashed lines in Fig. 2.

The distance A between the facing sides of the installations 7 and 10 is selected so that an unhindered passage of these cables 11 or cable guides is ensured for the desired installation case. If one assumes that, for example,

Typical four-core sheathed data or communication cables have a diameter

of about 8 mm, this means that when using such cables, the size of the gap A is designed to be 8 mm or somewhat larger, perhaps preferably 10 mm. However, other applications are also conceivable in which not four-core but only two-core or other cables are used, for which a gap width A of only 6 mm may already be sufficient.

In the embodiment of Fig. 1 and 2, the holder 9 has a specific design, as can be clearly seen in detail from the perspective individual representation in Fig. 5: The overall structure consists of a support frame 12, which in turn has a circumferentially closed individual frame 13 on its front and rear sides, whereby these individual frames 13 are connected to one another via depth struts 14, which can be designed, for example, in the form of register or holder rails with one or more parallel or offset rows of grid holes 15.

In the embodiment shown, each front and rear individual frame 13 is made in one piece from a sheet metal part and in turn has horizontally running crossbars 16 which serve as fastening bars for fixed intermediate floors 17, one of which is shown in Fig. 4 next to the support frame 12 in a perspective individual view. In the embodiment shown, each individual floor 17 consists of a shaped sheet metal part which, when installed, has a horizontally running central region 18 with longitudinal edges 19 turned up at the sides. At the front and rear end of the central region 18, a small strip-shaped crossbar 20 is angled downwards, which is provided with bore openings 21 which allow it to be fastened to the crossbars 16 of each individual frame 13 via associated counter-bores 22.

Each individual frame 13 also consists of a central region 23 lying in one plane with side legs 24 bent laterally by 90° in the direction of the opposite individual frame 13, whereby in the central region of each individual frame 13 above the mounted intermediate floor 17 between the crossbars 16 the openings for introducing components or groups of components are formed, as shown in Fig. 4.

The two one-piece individual frames 13, in conjunction with the depth struts 14, form a stable support frame 12, in which the installation of the intermediate floors 17 creates installation positions, e.g. for non-standard fittings.

The arrangement of the crossbars 16 on the individual frames 13 and the arrangement of the intermediate floors 17 is such that, for example, installations that do not conform to standards can be placed directly on the intermediate floor 17 without additional screw fastening, whereby they can be pushed or inserted through the corresponding insertion openings with the height H of each individual frame 13.

In the symmetrical arrangement according to Fig. 2, the shunting spaces R on both sides are each only half the width of the shunting space in the arrangement according to Fig. 1, which is why the receptacles 9 there can be designed with exactly the same structure as the receptacle 9 in the cabinet from Fig. 1, but only half as wide as this, so that a receptacle with a support frame 12, as shown in Fig. 3, can also be used here in exactly the same way. All statements regarding the support frame 12 and its relative arrangement to the receptacle device for the horizontally mounted built-in components 7 apply in exactly the same way as described in connection with Fig. 1. In this case, it is simply the case that between each side receptacle 9 and the middle receptacle device for the horizontally mounted built-in components 7, there is a free space extending over the height of the equipment cabinet 1 for the passage of cables, so that here the cable can be passed through on both sides of the horizontal built-in components 7.

!In Figures 4 to 7, further design options for other designs of the receptacles 9 are shown:

Fig. 5 shows the front view of an equipment cabinet 1, in the interior of which a holder 9 for (not yet attached) vertically and horizontally arranged components is mounted on each side wall 2 or 3 in preparation for a symmetrical shunting space arrangement.

As can be seen directly from Fig. 5, each of the two lateral mounts 9 acts both as a reducing rail and at the same time as a

vertical holding profile for one side of the receiving device for the horizontally mounted components. As can be seen from Fig. 5, a continuous vertical row of grid holes 26 is formed in the end area of each receiving device 9 facing the middle of the cabinet, while on the front side of each receiving device 9, on the cross members 16, horizontal rows of grid holes 25 are provided above and below the receiving openings formed there for the vertically mounted components.

In the design of the holder 9 shown in Fig. 6, a support frame 12 is used that corresponds completely to the support frame from Fig. 4, although here front frames 28, which are inserted into the frame openings of this individual frame 13, are attached to the crosspieces 16 of the individual frames 13 arranged at the front in the perspective view of Fig. 6. Such a front frame 28 is shown again in Fig. 6 outside the frame 12 and separately to the left of it below. This front frame 28 consists of a sheet metal with a flat front 29 in which a rectangular opening 27 is made, with a side web 30 protruding into the interior of the support frame 12 being attached from the front 29 to the vertically extending side edges of the opening 27.

Each front frame 28 is provided with a horizontal row of grid holes 25 directly above the upper horizontal boundary edge for the opening 27 and directly below its lower boundary edge, which can be installed in any grid dimension suitable for the formation of built-in components.

Such front frames 30 can, however, also be mounted in the middle area of the opposite individual frame 13 (additionally or only there).

On each front frame 30, two fastening holes 22 are provided at the top and bottom, above and below the horizontal row of grid holes 25, respectively, the position and distance between which correspond to the arrangement of the fastening holes 22 on the crossbars 16 of the individual frame 13 and by means of which the front frames 30 can be detachably fastened to the crossbars 16, e.g. by means of screws.

Finally, Fig. 7 shows a design for the support frame 12 in which the installations 32 are designed in the form of support frames that can be extended on telescopic rails (not shown in detail), the uppermost of which is shown in a partially extended position, while the other two extendable installations 32 are shown in their position pushed into the support frame 12.

Here too, each of these built-in elements 32 has a circumferential front frame 33 at its pull-out end, which is provided with a protruding sheet metal strip 34 at its upper and lower horizontal end edge, which serves as a stop when inserted.

All forms of support frame 12 shown in Figures 5 to 7 are equipped with depth struts 14, which could of course also be provided in a different position and arrangement than that shown in the figures. Likewise, if desired, it is also possible to attach similar cross struts to the opposite side of the support frame 12, which would then result in a support frame 12 in the form of a box frame.

In all the designs of support frames 12 shown in Figs. 5 to 7, the side webs 24 of both individual frames 13 (or just one of these side webs) facing the receiving device for the horizontal fittings could be provided with grid holes 35 arranged in a vertical line of any suitable or desired grid size, whereby, for example, a continuous vertical row of such grid holes could also be provided, for example corresponding to the continuous vertical row of grid holes 26 in Fig. 5.

The equipment cabinets 1 shown in the figures offer great flexibility and variation in the design of the individual components in relation to one another:
30

For example, the horizontally arranged components 7 can be designed according to the 19-inch design and the vertically arranged components 10 according to the metric design or vice versa or both according to the same design.

The receptacles 9 in the shunting spaces R can be designed in such a way that they are each designed in the sense of "integrated" reducing retaining profiles, which simultaneously serve to reduce the internal width and as a retaining profile for the horizontally arranged fittings 7. However, such a design can also be made in which, in addition to each receptacle 9, one or more vertical

Holding profiles 36 are arranged (Fig. 2), which serve as lateral holding profiles both for the holder 9 and for the adjacent holding device for the horizontal fittings 7, as shown in the sectional view of Fig. 2.
10

The installation levels for the horizontal components 7 can be located either at the front or at the rear.

It is also possible to use the vertically arranged fixtures 10

t,

to provide storage for non-grid and non-19-inch profile-based installation components.

In the drawings in the figures, the precise drawing of individual details, as is usual for such rack cabinets 1, was deliberately omitted for the sake of better clarity, which is why the representations of all figures, but especially those of figures 1 to 3, are shown as schematic and the lack of representation of individual elements that are usual or even necessary for such cabinets does not allow the conclusion that such elements are missing from the equipment cabinets shown.

The mounts 9 for the vertically arranged built-in components 10 can be assembled inside the cabinets 1 at the respective installation position. However, it is also possible to pre-assemble the mounts 9 as built-in units before assembly in the cabinet and then place them in the cabinet and secure them there.
