Description
TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to a wall rack for an office
workstation, in particular a PC workstation, which is completely
mobile in a freestanding embodiment and can be at least temporarily
fixed in place when mounted against a rear panel. The wall rack can
be used in permanent offices of companies, at trade fairs, at
conferences or in the domestic sphere. Tables, file trolleys,
cabinets and equipment boxes can be placed against the wall
rack.
PRIOR ART
[0002] EP 0 447 961 A2 discloses an office device which can be
combined in accordance with the modular principle, can be
configured in various ways, has various items of furniture and also
comprises partition walls. Diverse, individually adapted solutions
can be produced using the individual system components. However,
the partition walls shown only have the function of dividing up
space in order to form delimited work areas. However, the partition
walls are connected to one another in such a way that a certain
amount of effort is required to dismantle the device and set it up
again in a modified way. In particular in the case of situations
which change ad hoc, the partition wall which is proposed here
cannot be adapted in a sufficiently spontaneous way. With the
partition walls which are very simple per se it is indeed possible
to deal with conditions which arise suddenly, but, owing to their
simplicity, such partition walls provide only extremely limited
possibilities of configuring working space in an optimum way.
[0003] GB 1 388 051 discloses a wall rack which is composed of a
vertical panel of wooden material which rests on feet and is
connected to optional adjacent panels by hinged connections. On
each of the outer edges of the panel, a rail with a slotted grid is
mounted on the user side. Shelves and table leaves can be hooked
into the rail, with engagement hooks which are arranged on the rear
and correspond to the slotted grid. Telephone cables and power
cables are laid in a duct within the panel, near to the floor. This
wall rack is portable only to a limited extent and is configured
only for use on one side.
[0004] WO 98/16135 presents a wall rack with an enclosed, vertical
base frame which rests on feet and onto which a rear panel with
openings for cable accesses is fitted. Vertical stabilizing struts
and a plurality of spacing elements are fitted onto the front side
of the rear panel. The user-side front face is formed by a
perforated panel which is fitted onto the rear panel and which has
openings for cable accesses which are congruent with the rear
panel. In order to cover the cable accesses, two strip-shaped flaps
are provided which are suspended on an internally accommodated
lever mechanism in such a way that they can be pivoted up and down.
Shelves and a table leaf can be secured by means of supporting arms
which penetrate the rear panel and the perforated panel and can be
attached to the base frame at a selectable height. In order to hold
the supporting arms, drilled holes are made in a raster arrangement
on the base frame. An electric socket unit which is accessible via
the holes and is used for supplying power and for connecting to
communication leads is secured to the base frame. When the table
leaf is appropriately positioned in the vertical direction, a table
can be set up under it in order to increase the working area. If
the user wishes to use the wall rack as a workstation on both
sides, two such racks can be placed back to back and possibly
connected to one another. This wall rack is extremely
material-intensive, and equipping it with shelves or a table leaf
appears to be structurally too complicated and not able to be
modified to a sufficient degree. It could be particularly
unsatisfactory that the wall rack can in principle be used on only
one side; for use on both sides it is necessary to place a second
wall rack at its rear.
OBJECT OF THE INVENTION
[0005] In view of the inadequacies described above of existing
partition walls and wall racks for completely mobile or only
temporarily set-up workstations, in particular PC workstations with
requirements which change in many respects and the changing nature
of the organization of work in offices and changes in domestic
requirements, the invention is based on the following problem.
[0006] Taking as the basis a wall rack such as is disclosed in WO
98/16135, a wall rack is proposed with a reduced use of material,
which can be equipped with shelves on both sides at a selectable
height, and can thus be used on both sides as an office
workstation. The intention is that the wall rack will be capable of
being used both for a mobile office workstation which can be varied
ad hoc and as a fixed wall rack. The intention is that it will be
possible to combine the wall rack in a fashion which saves space
and which permits optimum configuration of working space in
companies, at a fixed location, for exhibitions or congresses and
for domestic use with equipment such as tables, file trolleys,
cabinets and equipment boxes.
SUMMARY OF THE INVENTION
[0007] The wall rack which is designed for an office workstation,
in particular a PC workstation, in a freestanding mobile embodiment
or with fixed installation comprises essentially an upright base
frame onto which a front panel is fitted on each side. Shelves of
various shapes and dimensions can be arranged and rearranged at
selected heights on one or both front panels.
[0008] Specific embodiments of the perfected wall rack are
described below: a manually accessible electric socket unit for
supplying power and/or connecting communication leads for equipment
in front of the wall rack is provided internally in the wall rack.
In the front panel there is an opening for leading through cables
which are preferably connected to the electric socket unit. The
opening can be divided into a plurality of sections so that the
cables can be led through to the equipment in, for example, three
planes. At least one pivotable flap for covering the opening is
fitted onto each of the two front panels. Preferably a strip-shaped
flap is provided on each side of the opening. All four are coupled
to an internally arranged lever mechanism.
[0009] In order to absorb sound, the front panels are perforated
with numerous holes. If necessary, the outer edges of the front
panels do not have any sound-absorbing holes. Arranged internally
in the wall rack is a damping inlay, preferably in the form of two
damping panels, which are each inserted between the base frame and
one of the two front panels.
[0010] The shelves are embodied as shelves for equipment or
utensils or as work surfaces which are also intended for holding
equipment or utensils and also as a work surface for the user. A
storage shelf is arranged on the front panel by means of a
supporting bar and two mounting pins. The supporting bar engages
below the storage shelf with its cross member on its front edge and
the supporting bar is supported with its two angled ends in one
sleeve-shaped socket holder each which is fitted onto the front
panels. The mounting pins are also fitted onto the front panel and
engage in engagement openings which are provided in the rear edge
of the storage shelf. A work surface is arranged on the front panel
by means of two bracket holders and shelf brackets. The bracket
holders are fitted onto the front panel and in each case one shelf
bracket, onto which the work surface is mounted, is fitted onto a
bracket holder. In order to use a relatively deep work surface
which is intended for relatively large loads, the shelf bracket has
at its front, free end, an adapter for mounting a supporting foot
which projects to the floor.
[0011] The cross member of the supporting bar is surrounded by
damping elements, for example made of rubber or plastic. A bushing,
for example made of plastic, is inserted into the socket holder so
that the end of the supporting bar which is to be plugged is held
in a slip-free, clamped fashion. The bottom of the socket holder
has an internal seat for the head of a screw whose threaded shaft
which projects through the floor is intended to engage in a screw
hole in the base frame, which hole is selected in accordance with
the desired vertical position of the storage shelf which is to be
mounted. An engagement opening in the rear edge of the storage
shelf is composed of a main drilled hole and a secondary drilled
hole which adjoins it at the top and is of smaller diameter. The
mounting pin has a cylindrical spacing segment and a stem element
which extends centrally therefrom and ends at the front with a
screw seat which is thicker in diameter in comparison with the stem
element. An axial drilled hole extends through the mounting pin. In
the mounted state, the spacing segment is seated on the front
panel, the secondary drilled hole is lowered onto the stem element,
the screw seat is located in front of the bent-up rear edge of the
storage shelf and the head of a screw, whose thread shaft projects
through the axial drilled hole and the front panel, and engages in
the selected screw hole in the base frame, in the screw seat.
[0012] Screw holes, preferably internally threaded drilled holes,
are systematically arranged in the base frame in order to mount the
front panels and bracket holders on both sides. The screw holes are
advantageously provided in a relatively small spacing arrangement
in the vicinity of the location where the bracket holders are
attached. In order to receive the cross member of the supporting
bar, the front edge of the storage shelf is also bent downward and
toward the respective front panel. The mounting pins, socket
holders and bracket holders are attached to the front panels by
means of screws which engage in the screw holes in the base frame,
through the front panels.
[0013] The base frame is composed of two U-shaped frame parts which
face one another with their open sides, are spaced apart and lie in
a vertical plane. U section is preferably used for the frame parts.
The open side of the U section points into the interior of the base
frame, while the base surface of the U section bounds the base
frame laterally and in the upward and downward directions. The two
section edges which surround the base surface of the U section
point to the fitted-on front panels. The screw holes are arranged
in the section edges.
[0014] In order to install the wall rack in a freestanding fashion,
a projecting wall rack foot is arranged on each of the two frame
parts of the base frame. When the wall rack is installed in a fixed
fashion, there is provision for it to be mounted on a rear panel or
on some other supporting structure, in which case the provision of
wall rack feet is generally dispensed with because it is sufficient
to arrange base elements on the two frame parts of the base
frame.

DETAILED DESCRIPTION OF THE INVENTION AND EXEMPLARY EMBODIMENT
[0027] The detailed description of a preferred exemplary embodiment
of the wall rack according to the invention with alternative
equipment variations is given below with reference to the appended
drawings.
FIG. 1A
[0028] The wall rack which is initially unequipped is composed
essentially of an upright base frame 1 onto which a front panel
2,2' is fitted from each side. In a freestanding arrangement, the
wall rack has two wall rack feet 3 which are placed on the floor
and are attached to the bottom of the base frame 1. An opening 20
for feeding through power supply leads and communication leads to
the equipment set up in front of the wall rack is provided in each
front panel 2,2'. The opening 20 is divided here into three
sections--corresponding to the three planes for the shelves which
are to be arranged. Internally, the wall rack has an electric
socket unit 5 which is manually accessible through the opening 20
and has the purpose of connecting power supply leads and
communication leads. Pivotable, strip-shaped flaps 4, which are
coupled to an inner lever mechanism in such a way that the flaps 4,
can be pivoted upward and downward on both sides of the wall rack,
and thus clear, or member off, the access to the opening 20, are
arranged on each side of the opening 20. The front panels 2,2' are
preferably screwed onto the base frame 1 by means of screws 99. In
order to absorb sound, the front panels 2,2' are provided as
perforated panels with an array of holes 21 which are located close
to one another.
FIG. 1B
[0029] The base frame 1 is composed of two U-shaped frame parts
10,10' which are located in a vertical plane facing one another
with their open sides and spaced apart. The U section is
advantageously used for the frame parts 10,10'. The open side 11 of
the U section points into the interior of the base frame 1, while
the base surface 12 of the U section bounds the base frame 1
laterally and in the upward and downward directions. The two
section edges 13 which surround the base surface 12 of the U
section point to the front panels 2,2' which are fitted on. Screw
holes 100 are arranged systematically in the section edges 13. The
wall rack has an internal damping inlay 6, which is preferably
embodied in the form of two damping panels which are each inserted
between the base frame 1 and one of the two front panels 2,2'. The
two front panels 2,2' and the damping panels 6 have the openings 20
which are cut out in a congruent position.
FIG. 2A
[0030] This illustration shows that two storage shelves 7 for
storing equipment and/or utensils are arranged on the front side of
the wall rack, i.e. on the front panel 2 at the front. At its rear
edges 701, the storage shelves 7 are mounted on the front panel 2
by means of holding pins 72, while supporting bars 71 engage under
the front edges 700 of the storage shelves 7 and are plugged, with
their bent ends 711 which are directed downward onto the front
panel 2, into sleeve-shaped socket holders 73 which are also
mounted on the front panel 2.
[0031] When the wall rack is installed in a fixed position, it is
mounted on a rear panel or another supporting structure and the
wall rack feet 3 are not required. For this installation there is
provision for base elements, on which the wall rack then rests, to
be arranged on parts 10,10' of the base frame 1. Exemplary
efficient mounting on a rear panel can be implemented with a
downwardly open U section element which is mounted on the rear
panel, at the height of the upper edge of the wall rack. The upper
edge of the front panel 2, which faces the rear panel, is pushed
into the section element from below.
FIG. 2B
[0032] In a further equipment variant, this wall rack has on each
side, i.e. fitted onto the two front panels 2,2', a storage shelf 7
and below it a work surface 8 with a large area.
FIGS. 3A TO 3F
[0033] A storage shelf 7 is arranged on the front panel 2 by means
of a supporting bar 71 and two mounting pins 72. The supporting bar
71 engages with its cross member 710 under the storage shelf 7 at
its front edge 700 and is supported with its two angled ends 711 in
one sleeve-shaped socket holder 73 each, said socket 73 being
fitted onto the front panel 2. The mounting pins 72 which are
fitted onto the front panel 2 engage in engagement openings 702
which are provided in the rear edge 701 of the storage shelf 7. In
order to receive the cross member 710 of the supporting bar 71, the
front edge 700 of the storage shelf 7 is bent downward and toward
the front panel 2. The mounting pins 72 are mounted on the front
panel 2 by means of screws 99 which engage in the screw holes 100
in the base frame I through the front panel 2.
[0034] The cross member 710 of the supporting bar 71 is surrounded
by a plurality of damping elements 712, for example made of rubber
or plastic. A bushing 74, for example made of plastic, for
receiving in a slip-free and clamping fashion the end 711 of the
supporting bar 71 which is to be plugged in is inserted into the
socket holder 73. The bottom 730 of the socket holder 73 has an
internal seat for the head 990 of a screw 99 whose threaded stem
991 which projects through the bottom 730 is intended for
engagement in a screw hole 100 in the base frame 1, which is
selected in accordance with the desired vertical position of the
storage shelf 7 which is to be mounted.
[0035] An engagement opening 702 in the rear edge 701 of the
storage shelf 7 is composed of a main drilled hole 703 and a
secondary drilled hole 704 which adjoins it at the top and is of
smaller diameter. The mounting pin 72 has a cylindrical spacing
element 720 and a stem element 721 which extends centrally
therefrom and ends at the front with a screw seat 722 which is of
thickened diameter with respect to the shaft element 721. An axial
drilled hole 723 extends through the mounting pin 72.
[0036] In the mounted state, the spacing segment 720 is seated on
the front panel 2, the narrower secondary drilled hole 704 is
lowered onto the stem element 721, the screw seat 722 is located in
front of the turned-up rear edge 701 of the storage shelf 7 and the
head 990 of a screw 99 lies in the screw seat 722, the threaded
stem 991 of said screw 99 engaging in the axial drilled hole 723,
projecting through the front panel and engaging into the selected
screw hole 100 in the base frame 1. When the storage shelf 7 was
engaged, it was possible to insert the screw seat 722, with the
larger diameter, of the mounting pin 72 screwed onto the front
panel 2 through the further main drilled hole 703.
FIGS. 4A AND 4B
[0037] A work surface 8 is arranged on the front panel 2 by means
of, in each case, two bracket holders 9 and shelf brackets 91,92,
the bracket holders 9 being fitted onto the front panel 2. In each
case a shelf bracket 91,92 on which the work surface 8 is mounted
is pushed onto a bracket holder 9. The screw holes 100 which are
present in the base frame I and which are preferably systematically
arranged holes with internal threads are used to mount the bracket
holders 9, with the result that the bracket holders 9 are fixed in
the selected vertical position by screws 99 which engage through
the front panel 2. For this reason, the screw holes 100 will be
provided in a tighter arrangement in the vicinity of the location
where the bracket holders 9 are mounted. In order to use a deeper
work surface 8 which is designed for larger loads, a modified shelf
bracket 92 has, at its front, free end, an adapter 920 for mounting
a supporting foot 93 which projects to the floor.
