Description
BACKGROUND OF THE INVENTION
In the tables hitherto known, steel frame components and wooden
components, that is, table top, drawers and shelves, constitute
coordinate parts all of which are joined to form the finished
table, whose rigidity and stability is the result of the rigidity
of the elements and their connection with each other.
FIELD OF THE INVENTION
It is an object of this invention to provide a table in which the
rigidity and the stability are derived from a steel tube frame
which consists of several elements which can be built together to
form various table lengths and on which various table elements such
as table tops, shelves and drawers can be mounted, so that many
combinations and writing tables of different sizes and design can
be made.
SUMMARY OF THE INVENTION
In accordance herewith the invention contemplates a writing table
having a steel tube frame to which there are attached elements such
as table tops, boxes of drawers and shelf boxes, the frame being
formed of two gable sections connected with each other by at least
two top girders serving to support one or more table tops, one of
the girders being located at the rear surface of the table, whereas
the other one is located at a substantial distance from the front
surface of the table, and at least one longitudinal girder located
at the rear surface of the table at a level corresponding to the
underside of a box of drawers, the said girders being connected
with the gable sections by means of screws or similar means of
attachment.
In a special, preferred embodiment, according to the invention,
there are attached to the two top girders of the frame, partly a
comparatively thin table top, preferably of steel and serving to
support the typewriter, partly one or more table tops of wood or
similar material, and means to dampen sound and vibrations between
the girders and the table top.
By this construction, there will be substantially no transmission
of vibrations from an electric typewriter, placed on the thin table
top, to the whole table, which would involve inconvenient operating
conditions. The design also embodies the advantage that the height
from the floor to the keyboard of the typewriter may be kept
comparatively low.
The invention is also concerned with means for supporting and
advancing a tape for a tape-controlled typewriter, in which the
extra equipment is efficiently protected and does not introduce any
inconvenience to the operator since the tape spool and the driving
means are swingable in a horizontal plane and mounted beneath a
portion of the table top adjacent the typewriter.
BRIEF DESCRIPTION OF THE DRAWING
Various embodiments of a typewriter table according to the
invention will now be described with reference to the drawing, in
which:
FIG. 1 shows the steel tube frame of the table with a table top
element for supporting a typewriter, viewed in perspective,
FIG. 2 shows a table top for the writing table according to FIG. 1,
viewed in perspective and on a smaller scale,
FIG. 3 is a section through a part of a top girder and the table
top, viewed from the side and on a still larger scale,
FIG. 4 shows a part of a writing table, viewed in perspective, with
a tape feeding device, and
FIG. 5 is the same as FIG. 4 on a smaller scale and with the said
device swung inwards.
The frame consists of two gable sections 1 and 2, each having two
legs 3 and 4 and two transverse bars 5 and 6. The legs rest on
adjustable feet 7. The parts of the gable sections may be joined by
welding so that each gable section forms a rigid unit.
The two gable sections are connected with each other by means of
three longitudinal girders, i.e., two top girders 8 and 9 and a
longitudinal girder 10 which is located at the rear surface of the
frame and connects the legs 3 at a location between the floor and
the top girder 8. The girders 8--10 are connected with the gable
sections by means of screws 11.
Attached to the frame is a table top element or a table top 12 of a
typewriter table, the said top 12 being formed of a comparatively
thin steel plate and attached to the top girder 9 and a transverse
bar 9a by means of three screws 13, shown in FIG. 3. The screws are
countersunk in a hole provided in the top 12 so that the head 14 of
the screw is flush with the table surface, and the screw extends
through a sleeve 15 of elastic, resilient material such as rubber.
The sleeve has a tubular portion 16 extending through a hole in the
upper wall of the top girder 9, and it has further a disc-shaped
portion 17 located between the said wall and the underside of the
table 12. At the lower end of the tubular member 16 is attached a
nut 18 by vulcanization, into which nut the screw 13 is
screwed.
When the screw 14 is screwed further into the nut 18, the nut will
be drawn upwards, by which the diameter of the tubular portion 16
will be increased and its curved surface will be forced towards the
inner walls of the top girder 9. By this means a completely
vibration and sound damping connection is provided between the
steel plate 12 and the top girder 9.
On the said table 12, which is thus insulated from the table frame,
is placed a typewriter, and to prevent the table from moving
laterally, the edge portions of the table top 12 may be bent
upwards so as to form edge rails for guiding the typewriter.
As indicated by chain-dolled lines in FIG. 1, a box for drawers 19
can be attached to the three girders 8--10 by means of screws 20 at
one side of the writing table. The drawer rests by its weight on
the girder 10, so that it is capable of resisting a very heavy
load. If desired, the drawer may be placed at the other side, or
there may be one at either side.
On either side of the table top 12 and on the rear side of the same
are placed wood table tops 21 (FIG. 2), retained by means of screws
through the girders 8 and 9. The table top 21 is only shown by way
of example, since it is possible to use a large variety of forms of
table top elements in connection with the table top 12 of the
typewriter table, and by disassembly several embodiments may be
produced on the basis hereof to suit different requirements of
operation; further, by substituting the girders 8--10 by
corresponding girders of a different length, tables of other
dimensions can be made. Such modifications require no expert skill
and can be made by the user in a short time by means of a
screwdriver.
The frame is of very great rigidity, and the top girder 9 is placed
so far back as not to be inconvenient to the operators legs which
may be positioned beneath the outwardly projecting portion of the
table top 12, which can thus be arranged at a comparatively low
level to give a suitable working height for the keyboard of the
typewriter.
As will be seen from FIG. 4, there is a distance between the box of
drawers 19 and the table top 21, and in the space thus provided is
mounted a device for winding a tape denoted by 22. The said device
consists of a supporting plate 23 swingable in a horizontal plane
around a pivot 24 which is screwed into the box of drawers 19, and
the device can thus be swung outwards into the position indicated
in FIG. 4 and inwards into the position indicated in FIG. 5, which
is the operative position.
On the supporting plate 23 there is mounted a tape roll 26 for
rotation about a vertical shaft 25, the tape 27 being passed over a
vertical tape roller 28 and a horizontal tape roller 29, from which
the tape, indicated by chain-dotted lines in FIG. 4, extends into
position in front of the typewriter 28 as shown in FIG. 5 and hence
into the typewriter. As will appear from FIG. 5, the tape feeding
device will not in its retracted position cause any inconvenience
to the operator, and when a fresh tape is to be mounted or a tape
to be removed, the device is readily accessible in the extended
position according to FIG. 4.
On the plate 23 is attached a funnel or channel 29, which at its
upper end has a flared inlet opening 30 which in the retracted
position of the device is located beneath the punching tool of the
typewriter, so that circular paper pieces punched from the tape
will fall into the funnel 30 and into the channel 29, which in the
retracted position is located just above a collecting box 30
attached to the table, so that the punched paper pieces are
collected in the box 30.
