TER SEA ■ MÜLLER ■ STElN ^ piSJ ^ R CARRIER PLATE FOR KEYBOARDS IN DATA PROCESSING SYSTEMS AND THE SAME

The invention relates to a support plate for keyboards of data processing systems and the like.

Such keyboards often form a separate unit that is only connected to a data processing system via cables. connected to a printer or other electronic device. There is therefore the possibility of to set up the devices mentioned outside the immediate work area of the operator, so that Flie operator has a largely free worktop. However, this also remains an obstacle fall the keyboard that is immediately in front of the operator.

The invention is therefore based on the object to provide a support plate for the keyboard that the Possibility of giving the operator a free worktop when the need arises and when the keyboard is not in use to provide.

This object is achieved according to the invention in that the carrier plate has lateral guide rails, which with Runner rails to be fastened under a table top work together.

The carrier plate can therefore be fastened underneath a table top in the manner of a pull-out or a drawer and, if necessary, can be pushed under the table top together with the keyboard. With a desk top In the usual amount, this results in the very desirable side effect that the keyboard in a

economically more favorable, lower height.

Keyboards of the present type usually rise towards the rear in the shape of a desk. Under the name "hintöh" In the present context, the side facing away from the operator should be understood * This results in on the rear side a relatively large height of the keyboard, which would lead to the support plate arrangement protrudes relatively deep under the worktop. This would reduce the legroom under the Affect the worktop.

According to an advantageous embodiment of the invention the carrier plate can therefore be lowered on the rear side before insertion or after it is pulled out can be raised and locked in the raised position.

In the following, a preferred embodiment of the invention is explained in more detail with reference to the accompanying drawing. 20th

12 for a keyboard in the extended position. According to

Figure 2 is below the table top 10 a guide

has the form of a Z- or U-shaped profile, in particular from j 5 sheet metal. A at a distance from the underside of the table plate 10 J opposed, horizontally in the direction of the support plate

12 protruding flange 16 engages at its edge in a cross-sectionally square running rail 18, which with <is connected to the carrier plate.

K The carrier plate has the shape of a flat, rectangular

'Trough with a bottom 20, side walls 22 and front

and back walls 24,26. As can be seen from Figures 1 and 3, the side walls 22 rise obliquely to the rear, i.e. to the right in Figure 3, so that the depth of the through the support plate formed trough increases towards the rear. The rear wall 26 is higher than the front wall This shape corresponds to the desk-like shape of a conventional keyboard, which rises towards the rear and is therefore surface, 20 can be inserted flush into the carrier plate 12.

'As can be seen from Figure 4, is in one piece with the side walls 22, a box-shaped profile 28 is formed which receives the running rail 18. A slot 30 in the outer surface allows the entry of the horizontal flange 16 of the guide rail 14.

12 an edge strip with an inverted U-shaped cross section

38.

At the top of the rear wall 28 is a similar but smaller edge strip 40 intended.

The outer layers of the side walls or profiles 28, which are not designated in FIG. 4, are provided in accordance with FIG. 3 by attachments 42 extended backwards. On these lugs 42 hooks 44 are attached with a downward crank 46. In the fully extended position according to FIG. 3, the carrier plate 12 can with respect to the guide rails 14 raised at the back and with the hook 44 be locked in recesses 48 in the guide rails 14. The base 20 is in this locked position the carrier plate horizontally, and at the same time it is fixed in the pull-out direction. When releasing the lock the carrier plate 12 is lowered again into the position shown in Figure 2, so that in particular on the left in Figure 2, the front edge of the table top 10 shown, the legroom is only slightly impaired.

In order to achieve the aforementioned ability to lift the carrier plate in relation to the guide rails 14, the running rails are used 18 are pivotably connected to the carrier plate 12 via axle pins 50 only in the region of their front ends. Since the chambers 52 formed on both sides of the carrier plate 12 within the box-shaped profiles 28 in their clear height to the rear wedge-shaped increase, the running rails can over the space between the upper and lower wall of the profiles 28 are pivoted. Since this pivoting according to the invention is outside the area of the guide rails 14 takes place / is this pivoting through cooperation of the horizontal flange 16 of the guide rails and the slots 30 are not obstructed. In the lower

In this position, the profiles 28 and thus the carrier plate 12 are supported in the manner shown in FIG the running rail 18 from.

The arrangement of the rails 18, which is mostly considered relative rigid sheet metal profiles are formed in the sides of the support plate offers the additional advantage of a considerable static relief of the carrier plate, so that the carrier plate, which is preferably made of plastic, with can be produced according to lower material costs.

An opening can be provided as a cable feed-through in the rear wall or at another suitable location.

Since the rails 18 within the lateral, box-shaped Profiles 28 of the support plate 12 are, the rail guide is not visible from the outside, so that neither the appearance is impaired, nor is there a risk of injury.
