EP0094376B1 - Arrangement with two oppositely adjustable and positionable work tops for carrying data processing appliances - Google Patents

Description

The invention relates to an arrangement with two mutually height or or and adjustable tilted worktops for carrying data processing equipment, in particular screen and keyboard, one of the worktables mounted on a base frame adjustable or height and the other worktop of at least one handlebar is worn.

In the field of data processing, the optimal adjustment of worktop heights and inclinations is often necessary. Usually a double and separately adjustable plate height per table is required, e.g. B. screen on the one hand and keyboard on the other. In this case, two height adjustment mechanisms are usually provided in a base frame. However, this solution is relatively expensive, since it is basically two racks.

From DE-A1 28 36 655 an office work table is known which has a support plate for an implement, which is height-adjustable, tiltable about a horizontal axis and pivoted about a vertical axis. The arrangement is such that first the support plate is pivotally mounted on a table top by means of a hinge pin about its vertical axis in its own plane, this table top also being fastened to a tilting frame which can be inclined by means of a horizontal shaft parallel to the table front edge.

This shaft is mounted in a carriage, which can be moved transversely to the front edge of the table top, and the tilting frame is additionally adjustable and fixable by means of an adjusting device arranged on the carriage. The carriage is mounted on slide rails that run transversely to the front edge of the table top, guided by a horizontal base frame, this base frame itself being fastened again on height-adjustable gas-sprung legs; furthermore, this base frame has a console for a keyboard in front of the table top, which is tiltable and height-adjustable independently of the table top. As a result, this well-known work table requires not only a large amount of space, but also a considerable amount of construction, which is complicated to assemble and difficult to handle.

The invention has for its object to avoid these disadvantages to create an arrangement. Of the type mentioned, which is characterized by particular simplicity in construction, assembly and handling and yet wide scope for different configurations required, with little space, allows.

According to the invention, this object is achieved in the arrangement mentioned in that at least one handlebar carrying a worktop is mounted on the other worktop. According to the essence of the invention, it is provided that this second worktop has a connection for the handlebar, which carries the former worktop, resulting in the simplest construction and assembly and safe handling.

A screw spindle is advantageously provided on the handlebar for height adjustment and adjustment. Such a screw spindle, the nut of which is guided in the handlebar and the upper end of which is rotatably mounted on the second worktop, enables the stepless height adjustment of the second worktop.

The design of the handlebar itself is according to further features of the invention that the handlebar is formed with one arm, or that the handlebar is designed as a U-bracket, or that the handlebar consists of two parallel links rigid torsionally connected.

In addition, it can be provided that the second worktop is also rotatably mounted on the handlebar, preferably about a vertical axis of rotation.

1 and 2, a foot frame is provided, in the vertical stand 2 height adjustable and adjustable a first worktop 3, z. B. is stored for a monitor (not shown). The height is adjusted by means known per se, which are not the subject of the invention. This first worktop 3 is provided on its underside with a handlebar 4, which is mounted at one end about a horizontal axis in a swivel joint 5 on the plate 3 and the other the second worktop 6, z. B. for a (also not shown) keyboard, u. between also pivotable about a horizontal shaft 7 and fixable in its inclination to the horizontal plane by known (not shown) means, z. B. by clamping or fixing screws.

To adjust and adjust the height of the handlebar 4 and thus the second worktop 6 relative to the first worktop 3, a screw spindle 8 is provided here, which carries a handwheel 9 at its rear end and is rotatably supported with its upper end in a plate 10 of the worktop 3 is. The spindle nut 11 is guided in the handlebar 4.

This arrangement enables the continuous adjustment of the second worktop 2 in height compared to the first worktop 3, u. by turning the handwheel 9. In the uppermost position of the handlebars, the two worktops 3, 6 are at the same height. In addition, the inclination of the second worktop 6 to the horizontal plane can be adjusted or set as desired.

The arrangement according to FIGS. 3 and 4 corresponds essentially to that according to FIGS. 1 and 2, with the difference that here a single-leg frame with base plate 12 is provided, which supports the stand 2, in which the worktop 3 is also additionally a vertical axis is rotatably mounted. A U-bracket 13 is provided as the handlebar, the web 14 of which has the pivot bearings 5 and the legs 15 of which are connected by a cross strut 16, in the center of which the screw spindle 8 is arranged.

5, two mutually parallel links 17 are provided, which are connected in a torsionally rigid manner by means of a shaped tube 18; in the cross strut 16, as in the arrangement according to FIGS. 3 and 4, the screw spindle 8 is arranged.

From the above it can be seen that the swivel joints 5 for the handlebars 4, 13, 17 may not necessarily be arranged on the first worktop 3, but also on its frame 1 or stand 2.

• Anstelle einer Schraubenspindel können gleichwertige Einrichtungen, z. B. eine Raststange, eine Zahnstange, eine Exzenterscheibe od. dgl. zur Höheneinstellung vorhanden sein.

Within the scope of these described exemplary embodiments, further changes can be made as required in order to adapt to the desired circumstances as required. For example, the following is specified:

• Instead of a screw spindle, equivalent devices, e.g. B. a locking rod, a rack, an eccentric disc or the like. For height adjustment.

The second worktop can also be rotatably supported about a vertical axis; a determination can also be provided for each desired corresponding position.

The handlebar (s) 4 can be cranked, that is to say they can project upwards with their free lower ends carrying the second worktop 6; this makes it possible to raise the height of the second worktop 6 beyond the first worktop 3 (FIG. 6).

In order to be able to adjust the horizontal distance between the worktops 3, 6, the handlebar (s) 4 can be adjustable in length, for. B. in that they consist of telescopically movable parts 4a, 4b, which can be fixed to each other in the desired length (Fig. 7).

It is also possible to arrange the second worktop 6 such that it can be removed from the position of use shown in FIGS. 1-4; for example, in that the pivot bearing 5 and the plate 10 are horizontally displaceably mounted on the worktop 3 so that the worktop 6 can be inserted under the worktop 3 (Fig. 8), or further in that the worktop 6 carried by the handlebar 4 by its shaft 7 can be folded away under the first worktop 3 (Fig. 9). The folding axis could also be formed by the pivot bearing 5; the handlebars 4 can also have such a folding axis, for example in the middle.

At least two links 4 ', 4 ", in particular in a U-shape, can also be arranged one above the other or next to one another in the manner of a parallelogram link system, provided a device for adjusting the height of their ends carrying the second worktop 6 to one another, such as two screw spindles 8 , whereby the inclination of the plate 6 to the horizontal plane can be adjusted (FIG. 10.11). In this case, one of the two links 4 ′, 4 ″ could also be designed to be adjustable in length, as shown in FIG. 7.

In order to be able to raise the height of the worktop 6 beyond the worktop 3, the U-shaped handlebar 13, as shown in FIGS. 3, 4, can also protrude the width of the worktop 3 with its legs 15, the cross strut 16 being trough-shaped is (Fig. 12, 13).

Another embodiment provides for the same purpose to let the legs 15 pass through slots 19 arranged parallel to one another in the worktop 3 (FIGS. 14, 15).
