Description
BACKGROUND OF THE INVENTION
The invention relates to a socket or mounting frame for a
switchgear cabinet or a rack, comprising mounting pieces which are
arranged, as corner pieces, in the corner regions of a rectangle or
square that extends in a x-y plane, said mounting pieces being
produced in a respective shaping process and comprising first and
second mounting faces which lie outside with respect to the
rectangle or square, which extend in the x direction and in the y
direction at a right angle thereto and which extend in a space
direction z at a right angle to the x-y plane, wherein sections of
a system of covers are brought into contact with the mounting
faces, said covers having lateral covers with cover walls that are
flat on the exterior and that have reinforcing ribs extending
longitudinally on the interior, and being fastened to receiving
structures of the mounting pieces by connecting means.
A socket or mounting frame for a switchgear cabinet of this type is
disclosed in DE 194 34 551 C1. In the corner regions of the socket,
which is rectangular in a top view, mounting pieces are arranged as
corner pieces which are connected to another by means of lateral
covers. The corner pieces are configured as upright profile
sections made of extruded aluminum profile comprising several
partly open and partly closed cavities running in longitudinal
direction of the profile and being confined by wall sections.
Mounting faces of the corner pieces which are outside with respect
to the socket comprise slots running in longitudinal direction of
the profile leading to rear side cavities which form T-shaped
fastening grooves via which the covers are mounted by means of
screws which engage nuts arranged within the grooves. Such
configuration results in a considerable mounting effort, in
particular if the covers must be removed and re-installed for
installation purposes e.g. at locations which are difficult to
access.
In another socket shown in EP 0 725 464 B1, the corner pieces
comprise an upper and a lower connecting plate which are connected
to another by means of rib-shaped vertical walls, wherein laterally
protruding fastening plates having bores are provided which covers
are mounted. Also this configuration can lead to unfavorable
mounting effort.
Further sockets which can be equipped with covers, are shown in DE
10 2007 013 520 A1, WO 02/080322 A1, DE 37 10 567 C2, DE 84 10 203
U1, DE 43 10 079 C2, DE 93 08 162 U1, DE 103 28 407 A1 and EP 0 686
316 B1. Those known sockets comprise corner pieces formed as angled
punched/bent parts to which the covers can be attached, while also
a considerable mounting effort is generated.
It is the object of the invention to provide a socket or mounting
frame of the type mentioned in the introductory, which improved
mounting possibilities are achieved.
SUMMARY OF THE INVENTION
This object is solved by providing a socket or a mounting frame for
a switchgear cabinet or a rack. The mounting frame comprises
mounting pieces which are arranged, as corner pieces, in the corner
regions of a rectangle or square that extends in an x-y plane. The
mounting pieces are produced in a respective shaping process and
comprising first and second mounting faces which lie outside with
respect to the rectangle or square, which extend in the x direction
and in the y direction at a right angle thereto and which extend in
a space direction z at a right angle to the x-y plane. Sections of
a system of covers are brought into contact with the mounting
faces, with the covers having lateral covers with cover walls that
are flat on the exterior and that have reinforcing ribs extending
longitudinally on the interior, and are fastened to receiving
structures of the mounting pieces by connecting means. The lateral
covers have cover fastening elements formed onto the interior of
the lateral covers and are fastened directly or indirectly to the
receiving structures of the mounting pieces by means of the cover
fastening elements. It is provided that the lateral covers have
cover fastening elements formed onto the interior of the lateral
covers and are fastened directly or indirectly to the receiving
structures of the mounting pieces by means of said cover fastening
elements.
Accordingly, the covers can be easily mounted and easily removed,
wherein fastening elements must not be mounted with much labour and
are also prevented to get lost. Thereby e.g. installation work in
particular at locations which are difficult to access, is
simplified.
Advantageous measures for production and also for mounting purposes
consist in that also the cover fastening element extend in
longitudinal direction of the lateral covers and that the lateral
covers are made of metal or preferably of plastics in an extrusion
process.
Handling during assembling is further promoted in that the cover
fastening elements are formed as clip elements or locking elements
having a flat insert slope and a steeplocking step and are engaged
or can be engaged, by means of resilient deflection, with
respectively adapted receiving structures at the mounting faces of
the mounting pieces or at other intermediate elements, such as
mounting rail or C-rail, extending between the mounting pieces and
mounted thereto with their end sections, to fix the lateral covers,
wherein the cover fastening elements and/or the receiving
structures can be resiliently deflected.
For mounting, also those measures have an advantage that the system
of covers also includes corner covers which are configured to cover
the outer corner regions of the mounting pieces.
Easy mounting is achieved in that the corner covers are provided
with corner cover fastening elements formed onto the interior
thereof by which they can be fastened directly or indirectly to
associated receiving structures of the mounting piece.
Those measures contribute to an advantageous production that also
the corner covers are made of metal or preferably of plastics and
are provided with reinforcing structures formed onto the interior
of plate-shaped corner cover walls thereof.
Those measures that the corner covers, on order to achieve at a
smooth transition from an exterior thereof to the exterior of the
lateral covers, comprise end sections overlapping facing and
sections of the lateral covers, which are inwardly offset by the
thickness of the cover wall in a z-shaped manner, positively
contribute to the optical designed also to a simple and unique
arrangement of the covers without producing undesired gaps at
transition places.
Further advantages for mounting are achieved in that the receiving
structures of the mounting pieces comprise receiving chambers
running parallel to the relevant mounting face, which are at least
partly surrounded by wall sections running in their orientation
direction and which are open at their front ends facing away from
each other, and/or that the receiving structures comprise receiving
ribs, receiving grooves, receiving bars, other protrusions and/or
other depressions and that at least a proportion of the receiving
structures is provided with fastening means, in particular locking
means formed thereon, which can be engaged with the covers and/or
with intermediate elements extending between the mounting
pieces.
By the measure that the mounting pieces terminate in z direction in
a first and a second base face oriented in the x-y plane, the
second base face being parallel and spaced apart from the first
base face by a distance, both forming the outer face of at least a
first and at least a second base wall section and that the mounting
faces are spaced apart from another at their ends facing towards
another and form a first corner space in the relevant first virtual
corner region of the mounting piece which can be covered with the
covers of the system, advantageous mounting possibilities are
offered in particular also in the corner regions, where
installation elements can be mounted beneficially and in a
systematic sequence a free space remains which complements a free
space existing in the edge region of an optional frame work
neighboring in z direction.
Further advantageous measures for mounting consist in that further
wall sections are coupled to the interior of the ends of the first
and second mounting face, which ends are facing away from another,
said wall sections being integrally connected and leave a second
corner space between their ends facing towards another, which is
confined in z direction by the first and the second base wall
section. For example, at a base wall section present in the second
corners space, an anchoring means having an anchoring claw for
fastening the socket to a supporting face can be advantageously
engaged.
For handling and fabrication, further advantageous measures consist
in that the mounting pieces are formed as block-like plastic molded
parts.
Further embodiment options are achieved in that for producing a
frame of double or multiple heights, two or more mounting pieces
are respectively arranged in the corner regions in said direction
and are connected to one another. It is advantageous that the
mounting pieces comprise complementary receiving structures on
their opposite base faces by which they can be positioned in a row
with outer contours aligned in z direction. Bores running in z
direction which are present in mounting pieces in a row and which
are aligned with another may be used advantageously for connection,
or there are gaging locking elements or other connection elements
acting in z direction.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1A and 1B as well as also FIGS. 2A to 2F and 3A to 3F
illustrate a mounting piece 1 in various views. Mounting piece 1 is
used as a fundamental construction part of a construction unit,
such as e.g. a socket 10 (e.g. FIG. 13 and FIG. 24A) or another
mounting frame, for mounting to a switchgear cabinet or rack or
another housing, preferably as a corner piece in the corner regions
of the construction unit which is preferably rectangular or square
in a top view. Mounting pieces 1 which are arranged in the corner
regions are connected by longitudinal extending intermediate
elements, such as mounting rails 32, rails 31 which are C-shaped in
cross section (C-rails) and/or lateral covers.
Mounting piece 1 is formed as a molded part produced in a molding
process, preferably as a plastic molded part or alternately as a
metal molded part, in particular made of a nonferrous metal, for
example of aluminum, or as a molded part of a compound material
comprising fiber material which is artificial and/or consists of
renewable raw materials which is e.g. embedded into a plastic
matrix. It possesses a block-like, roughly rectangular or cubic
shape with lateral parts oriented in three perpendicular space
directions, x, y, z as apparent from FIG. 1A.
Preferably, the ratio of two respective pairs of dimensions in x-,
y-, z direction is not more than 2:1, at best 3:1, the smallest
dimension in one of the three space direction being at least 5 cm
and the largest at most 20 cm. In a construction unit of the
previously mentioned configuration with mounting pieces 1, the z
direction of mounting piece 1 is perpendicular with respect to the
rectangular or square, respectively, extension plane of the
construction unit, while x- and y direction are running parallel to
(or in, respectively) the direction of the sides of the
construction unit.
As can be seen in the exemplary embodiment of FIGS. 1A and 1B as
well as in FIGS. 2A to 2F and 3A to 3F, it is symmetrically formed
with respect to a vertical diagonal plane extending in z direction
which extends from an outer corner region 12 of the mounting piece
1 (referred to below as a first corner region) to the opposite
inner corner region 11 of mounting piece 1 (referred to below also
as a second corner region), as mounted in a construction unit, and
is, on all outer sides, provided with receiving structures for
mounting elements of different type, including for example also the
mentioned rails 3, namely C-rails 31 and mounting rails 32, as well
as arrangement of covers 2, in particular lateral covers 22 and
corner covers 21 (cp. e.g. FIG. 16A).
As can be further seen in FIGS. 1A and 1B as well as in FIGS. 2A to
2F and 3A to 3F, first and second receiving chambers 132, 142 are
formed which are recessed from a first mounting face 13 parallel to
the x-z-plane, or lying there within, and from a second mounting
face 14 parallel to the y-z-plane or lying therein, respectively,
and which are oriented in x direction or y direction and are open
at their front end facing the relevant mounting face 13 or 14,
respectively, as well as to the opposite ends of mounting faces 13,
14. Having this configuration, end sections of rails 3 can be
inserted from the relevant mounting face 13 or 14, respectively, so
that even in an assembled state of a construction unit, later on
rails 3 or similar intermediate elements can be added or removed.
Moreover, rails 3 or the like can be introduced or inserted,
respectively, through the open front ends, so that e.g. benefit of
an initial mounting process of a construction unit may result.
Furthermore, fixing elements are formed within the first and second
receiving chambers 132, 142, which include first and second locking
catches 135'', 145'' comprising preferably locking pins fixed to
resilient tongues having locking slopes which are flat towards a
relevant mounting face and locking steps which are steep inwardly,
wherein the locking catches are perpendicular to the relevant
mounting face 13, 14 in y direction or x direction, respectively,
so that rails 3 or the like which are inserted from the relevant
mounting face 13, 14 are retained in a locked manner against their
insertion direction. The length of the locking catches to the steep
locking steps is advantageously adjusted to established cross
sections of rails 3 or distances to the rims of fixing holes
arranged therein, so that rails 3 or the like intermediate elements
are fixed in a correct position. The width of the locking catches
135'', 145'' extending in x direction or y direction, respectively,
is further advantageous adjusted to the width of relevant
rectangular or square fixing holes in particular of an established
row 312 of holes. Moreover, also the dimensions of the receiving
chambers 132, 142 are advantageously adjusted to the cross section
contour of rails 3 or the like, so that a trouble-free insertion
and a unique seat result.
Receiving chambers 132, 142 are surrounded by wall sections which
are at the top and bottom sides with respect to the vertical
direction (or z direction, respectively) and parallel to the x-y
plane and by another wall section 137, 147 parallel to the relevant
mounting face 13 or 14, respectively, wherein in the interior of
receiving chamber 132, 142 in the exemplary embodiment as shown
additionally reinforcing ribs are formed. The mentioned locking
catches 135'', 145'' are e.g. formed at a bordering wall of the
relevant receiving chamber 132, 142 parallel to the mounting
face.
As e.g. can be clearly seen in FIG. 1A, further receiving chambers
131, 141 are provided behind the wall section 137 or 147,
respectively, which is parallel to the relevant mounting face 13,
14 and which confine the relevant receiving chamber 132, 142 at its
rear side, which receiving chambers 131, 141 are continuously
confined by further wall sections, except for a gap 165 directed
upwardly in z direction, and which are open only at their front
ends towards the ends of mounting faces 13, 14 facing away from
another. Likewise, rails 3, such as C-rails 31 or mounting rails 32
can be introduced or inserted, respectively, into these additional
receiving chambers, namely from the top side through gap 165 or
from the front side. Likewise, connecting elements are located
within those receiving chambers 131, 141, for example additional
resilient locking catches 135'', 145'' which are formed thereto
which are adjusted to cross sectional contours of rails 3 or
distances to hole rims, respectively, to fix rails 3 or the like.
The connecting elements can further comprise fixing or positioning
ribs which are adjusted to cross sectional contours of rails 3 or
the like and which in addition result in a stiffening of wall
sections. Moreover, fixing holes 111 may be provided for
introducing further fixing elements into wall sections which are
accessible from the outside. In an alternate embodiment (not
illustrated), the additional receiving chambers 131, 141 or other
additional receiving chambers can be open and accessible from inner
sides spaced apart from the mounting faces.
Furthermore, the receiving structures on the mounting faces 13, 14
include further grooves 133, 143, additional locking catches 135,
145 or 135', 145', the latter extending along the relevant mounting
faces 13, 14 in x direction or y direction, respectively, and
comprising longitudinally extending grooves formed in ridge-shaped
holdings at the outside of mounting faces 13, 14, wherein pairs of
grooves having grooves open upwardly in a z direction and
downwardly on the respective mounting face 13 or 14, respectively,
which are preferably located in the same plane which is parallel to
the x-z direction or y-z direction, respectively. Opposing locking
noses which are formed e.g. on lateral covers 22 or corner covers
21, can be snapped into these pairs of grooves.
Furthermore, bolt-like locking catches 135, 145 having downwardly
extending locking pins are formed on the outside of the mounting
faces. Further, bar-like ribs 136, 146 are formed on the mounting
faces 13, 14 running in x direction or y direction, respectively,
which serve to position covers 2 and/or for stiffening.
Furthermore, wall sections 137, 137' surrounding receiving chambers
131, 132 or 141, 142, respectively, serve, apart from positioning,
for stiffening mounting piece 1.
Mounting piece 1 is confined in z direction by a first base face 15
(at the bottom in a mounted state) and a second base face 16 (at
the top in a mounted state) which form the outside of a first or
second base wall section 150, 160, respectively, and extend in
planes parallel to the x-y plane. Chamber-like cavities 153 (cp.
also FIGS. 20) and 163 which are open to the outside, are formed
perpendicular (in z direction) to the relevant base face 15, 16 in
the base wall sections, which cavities are completely or partly
confined (compared to the clear opening width) thin wall sections.
Further, gaps 165 connected with receiving chambers 131, 141 lead
into the second upper base face 1.6. Moreover, cylindrical holes or
bores are formed into both base faces 15, in the exemplary
embodiment as shown diagonally from the first to the second corner
region 12, 11 as well as adjacent thereto extending in z direction,
wherein at least some of the cylindrical bores 151, 161 are aligned
to another within both base wall sections. As shown in FIG. 1A, a
slot 152 is formed into the second corner region 11 in the first
base wall section 140 transversely to the diagonal between the two
corner regions 11, 12. Further, slot-like structures 162 are formed
into the outside of the second base section 160. Further,
structures protruding outwardly in z direction can be formed on the
base faces 15, 16, in particular on the upper base face 16, such as
protrusion 164 or bar-like protrusions 164' (cp. FIG. 13) extending
in x direction and in y direction, for uniquely positioning
construction components to be mounted to the upper side of mounting
piece 1, such as e.g. sections of a framework, a socket cover or
adapter plates. Moreover, the above mentioned cavities 163 or 153,
respectively, and bores 161, 151 can be used for positioning
purposes.
As further shown in FIGS. 1A and 1B as well as in FIGS. 2A to 2F
and 3A to 3F, three corner spaces 110 or 120, respectively, are
formed within corner regions 11, 12. Here, further mounting
elements can be inserted from the outside with free accessibility,
wherein the corner space which is outside with respect to a
construction unit can be covered with covers 2, in particular a
corner cover 21.
The corner cover can be fixed on the one hand, e.g. with the aid of
resilient locking elements formed on the interior side thereof and
correspondingly positioned, having locking slopes on the input side
and steep locking steps acting against the input direction at
locking catches 135, 145 and on the other hand in grooves 133, 143
which are upwardly opened.
The first or outer, respectively, corner region 12 is formed in
that mounting faces 13, 14 are spaced apart at their ends facing to
another and form a free corner space in the corresponding first (in
so far virtual) corner region 12 of mounting piece 1. First corner
space 120 is separated from receiving chambers 132, 142 on both
sides by means of respective corner region bordering walls 122,
122', said corner region bordering walls 122, 122' being
perpendicular to the respective mounting face 13, 14 and oriented
in z direction. In z direction, first corner space 120 is confined
by first and second base wall sections 150, 160. Bores 151, 161
arranged in the base wall sections confining first corner space 120
are aligned. Further, open recesses 156 are introduced into a side
of the lower base wall section 150 facing the first corner space,
which are open from the walls laterally from the diagonal to the
respective mounting face 13, 14, so that the corresponding bores
151 are better accessible for inserting mounting elements, as is
shown in FIGS. 5A and 5B, wherein as a mounting element an
adjustable leveling unit 62 is inserted into the aligned bores of
the first and second base wall sections 150, 160. Both base wall
sections 150, 160 form abutment rims for a cover defined at their
outer rims, in particular for corner cover 21, so that a defined
corner region is formed.
Second corner space 110 in (in so far virtual) second corner region
11 is formed in that additional wall sections integrally connect to
the interior sides of the ends of first and second mounting face
13, 14, facing away from one another. As e.g. shown in FIG. 1A, the
already described receiving chambers 131, 141 are arranged in these
regions, wherein i.e. in the depth of the receiving chambers
inwardly protruding wall sections are present. Between the wall
sections, at the ends facing towards another, the second corner
space 110 is formed as a free space. This free space is laterally
confined by second corner region bordering walls 112, 112' which
are parallel to the adjacent mounting faces 13, 14 and oriented in
z direction, and confined in z direction by means of the first and
second base wall section 150, 160, wherein fixing holes 111 leading
to receiving chambers 131, 141 are introduced are introduced into
corner region bordering walls 112, 112', and slot 152 is introduced
into a side of the first base wall section 150 facing towards the
second corner space 110, wherein an anchoring claw 41 having an
angled flat retaining lug 410 (cp. FIG. 7) for anchoring an
installed construction unit to a supporting surface can be
inserted. In the second corner region 11, interior regions of both
base sections 150, 160 of a construction unit are rounded (so that
in this respect the mathematically precise corner is only virtual).
Also second inner corner space 110 offers advantageous
possibilities for mounting and can be easily accessed, e.g. from
the interior of a switchgear cabinet after removal of a bottom
plate which optionally covers a socket. Access is also created
after removal of a lateral cover. Alternately, second corner space
110 can be formed by means of wall sections running at an angle
with respect to x-y direction and z direction or by only one wall
section running at an angle.
By means of base wall sections 150, 160 extending also across
corner spaces 11, 12, large receiving regions for building
extensions on both sides in z direction or a support on an underlay
are achieved on their exterior or base face 15, 16, respectively.
Cavities 153, 163 and bores 151, 161 having respectively relative
thin wall sections result in stable support structures in
particular in z direction as a honeycomb structure type, however,
the cell-like cavities being not identical, but can be used as
differently embodied functional regions with the receiving
structures, including those regions of base wall sections 150, 160
extending across corner spaces 110, 120. In the center region
between corner spaces 110, 120, the wall regions surrounding
cavities 153, 163 or bores 151, 161, respectively, form optionally
continuous supporting structures in z direction between both base
faces 15, 16 or supporting structures supported by wall sections
extending parallel to base faces 15, 16. Wall sections running in x
direction and y direction are also relatively thin and result,
together with reinforcing ribs, also in x direction and y direction
a high stability with relatively small use of materials and
accordingly relatively light construction of the mounting piece. In
particular, if configured as a plastic molded part, apart from
relatively thin wall sections, it is ensured that transition
regions, such as crossing and corner regions between wall sections
include material volumes as small as possible, so that the molding
process is promoted at high dimensional stability. Structures and
materials as mentioned, in particular plastics or composite
materials, of the mounting piece 1 further result in benefits of
vibration isolation with respect to vibrational and damping
properties.
As shown in FIG. 4, identical or different mounting elements can be
attached at mounting pieces 1 in different combination, wherein
FIG. 4 shows covers 2, namely a corner cover 21 having a first and
a second leg, as well as side covers 22 having a cover wall 220 and
cover fixing elements 221 formed in the interior side facing to the
mounting piece, rails 3, namely a mounting rail 32 having base legs
310, lateral legs 311 perpendicular thereto which in turn are
provided with angled free end sections and rows 312 of holes
provided in the base leg 310 and side legs 311, an anchoring means
4, namely an anchoring claw 41 having a front side flat retaining
lug 410 at an angle, supporting means 6, namely a castor unit 61
with castor wheel 610, supporting plate 611 and retaining member
612, a leveling unit with leveling sleeve 620 and leveling bolts
621 as well as a cylinder-shaped thread insert 5 which can be
inserted into a corresponding adapted bore 151, 161.
As shown in already mentioned FIGS. 5A and 5B, leveling unit 62
with leveling sleeve 620 and leveling bolt can be inserted e.g.
into first corner region 12 when corner piece 1 is used e.g. for
building up a socket 10. Leveling unit 62 protrudes into a bore
existing at a respective location in upper base wall section 160,
and with its adapted upper bolt section, into the lower section of
leveling bolt 621 into bore 151 aligned therewith in z direction.
For easy insertion, an open recess 156 is provided on the upper
side of the lower base wall section 150 which is open towards the
respective mounting face 13, 14. Leveling sleeve 620 is supported
at those regions of base wall section 160 surrounding bore 161 with
its band-like upper side, while leveling bolt 621 with its lower
end section, protrudes respective bore 151 downwardly and can be
screwed in or out more or less by means of a tool engaged on a
hexagonal section of leveling unit 62.
FIG. 6 shows a supporting stand 63 inserted into first corner
region 12 as a supporting means 6, having a stand plate and a stand
pin 631 protruding through a corresponding bore 151.
FIG. 7 shows a corner region of a partly assembled construction
unit, for example a socket 10, comprising a mounting piece 1, rails
3 connected thereto via receiving chambers 141, 142, namely a
C-rail 31 and a mounting rail 32, and an anchoring means here in
form of an anchoring claw 41 which engages slot 152 in lower base
wall section 150 in the inner corner region 11 with an angled flat
retaining lug 410, which slot is adapted thereto in size and shape
to a large extent. Such a construction unit, a socket 10 or
mounting frame, offers advantages in the installation of electrical
components and/or air-conditioning components or energy storage
components, e.g. for attachment, using retain struts, if needed,
which can be easily mounted at mounting rails 32.
Also in construction units which are partly assembled and in
sections shown in FIGS. 8A and 8B, a C-rail 31 and a mounting rail
32 are coupled to a mounting piece 1. A castor unit 61 is attached
beneath mounting piece 1. Further, in FIG. 8B an anchoring claw 41
mounted to mounting piece 1 is illustrated.
FIGS. 9A to 9D show different embodiments of castor units 61
wherein in FIG. 9A a castor unit 61 mounted at a mounting piece 1
is illustrated. Castor unit 61 protrudes through a bore 151 in the
lower base wall section 150 in inner corner region 110 with a
bolt-shaped retaining member 612. The retaining member comprises
some type of bayonet connection, bore 151 being accordingly adapted
for passing a protruding cross bolt. FIG. 9B shows a
correspondingly embodied castor unit 61 with supporting plate 612
and retaining member 612 with bayonet connection. FIG. 9C shows a
castor unit with bayonet connection without supporting plate and
FIG. 9D a castor unit with additional leveler with stand plate
630.
Alternate exemplary embodiments for castor units 61 are shown in
FIGS. 10A and 10B which can be engaged and attached, with
block-like retaining member 612', laterally to wall regions of
mounting piece 1 merging into the second corner region 11.
In FIGS. 11A and 11B, further sections of a corner region of a part
assembled construction unit, for example a socket, are illustrated,
wherein rails 3, namely C-rails 31 and mounting rails 32 are
attached or can be attached, respectively, at both mounting faces
13, 14. FIG. 11C shows a corresponding lateral view. As apparent
from the Figs., mounting rail 32 can easily be inserted into a
respective receiving chamber 132 or 142, respectively of mounting
piece 1 even later on after having removed an optionally existing
cover. Mounting rail 32 locks onto resilient locking pin 135'' or
145'', respectively.
FIG. 12A shows a construction unit which is square in a top view,
as an example a socket 10, with mounting pieces 1 arranged in four
corner regions and intermediate elements in form of C-rails 31 and
mounting rails 32 connecting them, as previously explained, coupled
to corner pieces 1 with their end sections. FIG. 12B shows a socket
10 from one side while FIGS. 12C and 12D reproduce sections of the
corner regions of socket 12 in an enlarged illustration. For
example, relatively narrow configured C-rails 31 can be introduced
with their narrow sides from above into gaps 165 and then, if
needed after lateral displacement, be interiorly fixed in
respective receiving chambers 131, wherein they are rearwardly
engaged by relevant locking catches 135'' on their one side and are
fixed (cp. also e.g. FIG. 1A). Advantageously, C-rails can be used
in the socket region of a switchgear cabinet for securing lines,
such as e.g. electrical cables. Rows 312 of holes having square or
rectangular holes in a defined spacing and optionally intermediate
round holes are advantageously aligned with corresponding holes or
rows of holes, respectively, of mounting rails or frame profiles of
the switchgear cabinet or the framework thereof, respectively. As
may be recognized in FIG. 12D, the outside second corner region 120
is free for access from front end side, after optional covering
cover elements have been removed.
A respective construction unit, for example a socket 10, as in FIG.
12A, is also shown in FIG. 13, but in a perspective top view. On
the upper outside, a presently square support surface with
receiving structures is formed, when in the outer frame region
ledge-like protrusions 164' extending in x direction and y
direction are molded to the upper base wall section 160. Adjusting
screws or connection screws are inserted into interior corner
spaces 110 in relevant bores 151, as may be recognized from corner
space 110 illustrated rearwardly in the FIG. (at the upper side on
the drawing sheet).
FIGS. 14A and 14B show further exemplary embodiments of
construction units in form of partly assembled sockets 10. In FIG.
14A, a rectangular socket having mounting rails 32 as connecting
elements is shown, whereas FIG. 14B shows a square socket 10 having
mounting rails 32 and C-rails 31 as intermediate elements or
connecting elements, respectively. Respective corner pieces 1 are
arranged in the corners according to the previously described
embodiment.
FIGS. 15A and 15B, interned, show corner regions of a construction
unit with mounting rails 32 or C-rails 31, respectively, coupled
thereto. Thread inserts made of metal are inserted into some of the
bores 161. An Allen screw is introduced into center bore 161, as
shown in FIG. 15B. By taking those measures, mounting of e.g. a
frame section of a frame work can be made on the upper side of the
mounting piece. Protrusions 164, 164' define abutment positions and
result in a precise positioning.
FIG. 16A and 16B illustrate a cut-out of an arrangement of covers 2
at a mounting piece 1, wherein in FIG. 16A the corner region
illustrated in FIG. 16B is enlarged. Cover arrangement 2 comprises
two lateral covers 22 which are mounted to the mounting faces 13,
14 of mounting piece 1, as well as a corner cover 21 which covers
the outer corner space 120 outwardly in an assembled state.
Preferably, lateral covers, as also shown in FIGS. 18A and 18B, are
made as metal profile sections or preferably made of plastics (or
even of compound material, such as fibers of artificial material or
renewable raw materials embedded into a plastic matrix), comprising
a flat cover wall 220 on their outside, wherein cover fixing
element 212 or reinforcing ribs 222, respectively, are molded to
the inner side. Stiffening ribs 222 or cover fixing elements 221
can also protrude perpendicular in the longitudinal edge regions of
cover wall 220, as may be recognized in FIG. 16A. Also, cover
fixing elements 221 may serve as reinforcing elements, so that it
is possible to do without other individual stiffening ribs.
Ledge-like cover fixing elements 221 are provided with locking pins
at their free end sections comprising, towards their free end, e.g.
in insert direction, flat insert slopes and, opposite to the insert
direction, more or less steep locking flanges. Ledge-like cover
fixing elements 221 advantageously form resilient locking tongues
which can be deflected against their elastic spring forces. They
cooperate with locking structures arranged at mounting faces 13 or
14, respectively, to which they are adapted. In the exemplary
embodiment, this is achieved e.g. by ledge-like locking catches
135', 145' which are open downward or upward, respectively (with
respect to the z direction) and which lockingly snap into
oppositely directed locking pins of two respective cover fixing
elements 221. Stiffening ribs 222 and ledges protruding from
mounting faces 13, 14 may serve for stable support in a precise
position. FIGS. 18A and 18B show lateral covers 22 from the inside
or from the front end, respectively.
Preferably, also corner cover 21 is made as a molded part of metal
or preferably of plastic (or even of the mentioned composite
materials). First and second legs 210, 211 are also formed by a
cover wall 220 which is flat on its outside and corresponds in its
height (z direction) essentially to the height of the lateral
covers 22. On the inner side of legs 210, 211, tongue-like or
ledge-like protruding corner cover fixing elements 212 as well as
ledge-like stiffening ribs 213 are molded, as can be seen in
particular in FIGS. 17A to 17F. Corner cover fixing elements 212
form preferably resilient locking protrusions with locking pins
molded to the cover wall, wherein two locking protrusions 212
spaced apart in z direction are oriented opposite to one another
with their locking pins and snap into correspondingly positioned
grooves or locking protrusions, respectively, on the mounting faces
13, 14, when inserted. Also, the locking pins of the corner cover
fixing elements 212 are provided with flat insertion slopes in
insert direction and preferably also carry steeper locking flanges
on their sides arranged opposite to the insert direction. For
example, locking catches 135, 145 and 133, 143 on the outside of
mounting faces 13, 14 serve as locking protrusions for snapping in
corner covers 21.
Advantageously, the covers can be formed to perform switchgear
cabinet functions, for example can be provided with ventilation
openings and/or recesses or receptacles of grids, conditioning
mats, fans or the like.
FIG. 19A shows a cut-out of a corner region of a construction unit
comprising mounting rails 32 and C-rails 31 mounted to a mounting
piece 1 as well as removed lateral covers 22 and a corner cover 21.
FIG. 19B shows a socket 10 having covers 21, 22 mounted thereto and
comprising C-rails 31 and mounting rails 32. Corner covers 21 cover
the respective outer corner spaces 120 of corner pieces 1. Lateral
covers can additionally abut at intermediate elements, for further
support, in particular to mounting rails 32, and can optionally be
locked therewith. Thereby, an additional stabilization of lateral
covers 22 is achieved.
FIG. 20 shows a cut-out of another corner region of a construction
unit. Herein, a mounting rail 32 and a C-rail 31 are mounted to a
mounting piece 21 which their end sections at receiving chambers
141, 142 at the mounting face 14 of mounting piece 1. In the lower
region of mounting face 13, a wider mounting rail 32' is inserted
into respective locking protrusions or grooves, respectively, and
protrudes with its edge region facing away from the mounting face
13 so that it can be engaged with corresponding receiving
structures on the mounting face of a neighboring corresponding
mounting piece 1. In this way, a side-to-side sequence of
construction units, such as e.g. sockets, in a defined arrangement
and with stable connection is achieved. This is shown in FIG. 21,
where the wide mounting rail 32' protrudes into the respective
receiving chambers of neighboring mounting faces of two mounting
pieces 1 and is locked therein. For locking, again protruding
locking catches can be used which are molded to the mounting faces
13, 14 of mounting pieces 1 and which interact with holes of rows
312 of holes positioned in mounting rail 32'.
FIGS. 22A and 22B show various adapter elements 7 including adapter
plates 70, 70' and connecting elements 71 adjusted therewith. FIG.
22A shows a substantially triangular adapter plate 70, whereas FIG.
22B shows a rectangular adapter plate 70'. The adapter plates
comprise fixing holes as well as protruding protrusions on their
flat sides. The protrusions and fixing holes are adjusted with
complementary impressions on the upper and/or lower based surface
15, 16 of the mounting piece 1, e.g. also on their rim region,
wherein the fixing holes are also aligned with suitable bores
within the base surfaces 15, 16. By means of those or similar
adapter plates, adjustments to various structures are coupled to
mounting pieces 1 via adapter plates.
FIG. 22C shows a corner region of a framework 8 of a switchgear
cabinet which has a vertical frame profile 81 and horizontal frame
profiles 82, mounted or to be mounted on a mounting piece which is
not shown. FIG. 22E shows a schematic cross section illustration of
the vertical frame profile 81 is illustrated, wherein two
essentially square or rectangular hollow chambers or profile
sections 810, respectively, are connected to another via a
diagonally extending connecting web 811. Having such a profile
cross section, free spaces on the outside in a vertical edge region
of a framework or switchgear cabinet, which are inside and outside,
are formed which form advantageous mounting spaces for mounting
installation elements, such as e.g. connection elements for side
planking, hinges or locking elements. If the profile sections 810
are provided with narrow abutment or sealing ledges protruding
outwardly, advantages are generated for close row mounting, as it
is known from relevant applications of the applicant. The free
space formed in the edge region is systematically preceded within
vertical direction when assembling a construction unit or a socket
10 of the previously described construction with mounting pieces 1
comprising free corner spaces 120 in outer corner regions. Thereby,
assembling benefits are generated.
FIG. 22D shows an example for using a bearing sleeve in a bore of
corner piece 1 which may advantageously be used for receiving a
connecting pin, for example of a castor unit 61 or a supporting
stand 63.
FIG. 23 shows row mounting of two mounting pieces 1 in z direction.
Receiving structures on both base faces 15, 16 are adjusted to
another so that the mounting pieces placed one above the other do
not displace in x- and y direction and can easily be connected e.g.
by means of a screw inserted into the corner spaces 110, 120 which
(unv.) through the aligned bores 151, 161, as can be seen in FIG.
23, in particular, if thread inserts are inserted into bores 161 of
the upper base wall section 160. In this way, construction units,
such as e.g. socket 10, can be combined in a double or multiple row
mounting and may reach a multiple height. They can be easily
covered with respective covers of the previously mentioned
constructions or with double or multiple covers.
FIG. 24A shows a lower section of a framework 8 of a rack or a
switchgear cabinet mounted on a socket 10 with mounting pieces 1.
The framework comprises vertical and horizontal frame profiles 81,
82 of the previously mentioned type, wherein vertical profiles 81
form free spaces in the outer edge region and inner edge region
resulting in advantages assembling possibilities, as previously
explained. The mounting pieces in turn offer free corner spaces
110, 120, as described. Mounting rails 32 are provided with rows
312 of holes having the same spacing as the hole screen provided in
horizontal frame profiles 82 and vertical frame profiles 81,
wherein hole screens of mounting rails 82 and horizontal frame
profiles 82 are aligned with another at least in a vertical
direction. Further, C-rails 31 for securing lines, in particular
cables, are inserted into mounting pieces 1, as also previously
explained. In the inner corner space of vertical frame profiles 81,
connection screws are inserted into stabilizing receptacles
positioned therein which proceed on the lower side of a lower frame
of framework 8 formed by horizontal frame profiles 82 and engaged
in accordingly positioned bores 161 with thread inserts 5
introduced therein. Connecting screws passing there through are
advantageously positioned in the outer corner region 12 or the
outer corner space 120, respectively. The upper side of the upper
base surface 16 of mounting piece 1 is adapted to the bottom side
of horizontal profiles 82 regarding its receiving structure, so
that e.g. protrusions may engage into corresponding holes and/or
the outer corner region of horizontal profiles 82 is in sections
confined by outer ledge-like protrusions 164. FIG. 24B shows a
lateral view of the lower section of framework 8 mounted on the
socket, FIG. 24C a top view, and FIGS. 24D and 24E show, enlarged a
corner region in a lateral view or in perspective view,
respectively. Framework 8 can be connected with corner pieces 1 by
means of screws, locking elements or clip elements and/or clamping
elements.
FIG. 25 shows another corner region of a framework 8 having
horizontal frame profiles 82 and a vertical frame profile 81,
mounted on a socket 10, wherein a horizontal profile extending
perpendicular to the drawing plane is illustrated in cross section.
It forms in its virtual outer edge region a continuous free space
where only a ledge-like connection section is protruding, moreover,
also in this region beneficial mounting possibilities are offered.
The flat bottom side of horizontal profiles rests stably on the top
surface of the socket, in particular also on the mounting pieces 1
(not shown in this illustration).
FIG. 26 shows a side-to-side arrangement with two neighboring
sockets and frameworks 8 in a corner region. Horizontal frame
profiles are opposite to one another, having narrow abutment bars
between which a sealing element is introduced. They rest stably on
a respectively associated top surface of two sockets 10 with their
flat bottom surface. A row of sockets of e.g. benefits in
pre-installation, so that frameworks or switchgear cabinets or
racks in a row can be easily positioned and only need to be
fixed.
FIGS. 27A, 27B and 27C show corner region of a socket with a
schematically illustrated mounting piece 1 to which a cover
arrangement having lateral covers 22 and a corner cover 21 is
mounted. In FIG. 27B, further a part of a switchgear cabinet wall
arrangement 9 with switchgear cabinet wall element 90 is shown.
FIG. 27C shows a corner cover 21 in a sectional view, wherein free
end sections are offset inwardly by about the thickness of the wall
section in a Z-shaped manner, so that the lateral blends can
overlap the offset free end sections of corner covers 21, so that a
flushing transition of the outer surfaces is achieved.
FIG. 28 shows a cut-out of a socket having lateral covers and
corner covers, enlarged with respect to FIG. 27A, as well as a
cut-out of a switchgear cabinet having a switchgear cabinet wall
arrangement 9 with switchgear cabinet wall elements 91 and e.g. a
door 91.
FIG. 29 shows a lower framework section mounted to an uncovered
socket with mounting pieces 1, where in a socket region levers of
lifting equipment are introduced. Mounting pieces 1 form
advantageous distance pieces for introducing the levers similar to
a pellet. Thereby, transporting benefits are generated.
A construction unit assembled by means of mounting pieces 1 can not
only be used as a socket 10, but for example also as an
intermediate frame between the frameworks 8 mounted above the
other, or as a top part frame. Even a use as mounting frame is
conceivable. The z direction of the mounting pieces may be oriented
in horizontal direction, or the plane of the construction unit,
such as mounting frame, may be vertically oriented.
