PATENTEB HAYZS l97| SHEET 1 [IF 2 PATENTED W25 lsn SHEET 2 OF 2 TYPEWRITER TABLE 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. I, 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 8I0 are connected with the gable sections by means ofscrews I1.

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 8l0 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 l9 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 l9, 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.
