Pulpit for a screen apparatus.

p0001The invention relates to an apparatus for laying of manuscripts, documents and other documents in the proper viewing distance and viewing height for ergonomically correct work on computer and word processing systems. The device is thereby attached directly to the screen device housing, on or clamped by this, or is located directly in the region of this housing.

p0002Devices for Placing Documents are known in various forms and be placed near the data input devices darzubieten to the operator the documents in appropriate viewing height and distance vision. These devices are usually placed side of the terminal, directly supported on a tabletop, or clamped to a desk edge and supported by an articulated arm. These known devices have the disadvantage that they require space on the desk or in the case of an articulated arm, the pivot point of the shelf plate too far back is on the panel edge and so the manuscript can not be in the best of the eye angle of view presented in any case, especially if it is to be partially positioned in front of the screen. These structures are not fixed sufficiently stable, and without holding the shelf in addition, for example, can not freehand written or stamped on the manuscripts, which z. Part are needed in practice, especially if brief information of numerous manuscripts or templates in the data unit inputted be such as payment transactions in banks.

p0003The invention is now based on the object trainees a device of the type described above so make that no storage space is required on the workstation for the manuscript or its holder that the shelf of the manuscript holder is fixed enough so attached freehand notes on the manuscript can be, and that the manuscript can be easily placed in their optimal position for ergonomically correct work. The demand for low space requirement of the manuscript holder to data terminals is satisfied that the document holder as directly laterally clamped to the terminal housing by adjustable support arms and its pivot bearing plate is supported on the housing above. When not in use the shelf can be stationed along the sides of the housing and also requires no usable space. It is also possible that parts of the manuscript holder to be adversely affected by the weight of the terminals, in that these parts are formed as feet, bottom bracket, etc., and are pushed under the terminal. Or it can be secured, the fulcrum bearing plate of the pivot arm on a telescopic hanger support and this will be anchored in the console or to a desk edge. The demand for the positioning of the manuscript for the best viewing angle for ergonomically correct work is for example achieved in that the height-adjustable shelf panel is connected by a universally movable joint having a rotating arm with slotted guide, which circularly moved with larger or smaller radii to the front of the terminal and can be locked in any position. In addition, the pivot point of the pivot arm can be laterally also moved eg in a slot guide, so that a great mobility results in the positioning of the manuscript.

p0004The demand for sufficient fixation of Manuskri_Dt-plate was met by the rotation arm is locked at a second point in the pivot bearing plate, in a direction parallel to pivot slot guide second mounting slot guide with moveable attachment point or in each rotation or mounting bearings. In addition, the axis of rotation of the manuscript panel is also locked at a second point, this example in a centrally running to the plate axis circular groove with bolt and nut. The manuscript itself is placed on the edge of the shelf plate and eg fixed with a clamp.

p0005The tray plate must not necessarily be flat, it may also be used a roll, whereby the manuscript sheet obtains a bent shape, thus requires less space and is even more suitable for placement in front of the front of a data unit.

p0006The invention is shown in the drawings together with the data terminal housings, without keyboard, as follows:<ul><li>Figure 1 in front view with side clamp on the housing.</li><li>Figure 2 in plan with clamp on the housing.</li><li>Figure 3 in the side view of a version with bracket rod and bottom bracket.</li><li>Figure 4 in the front view as a further variant with bottom bracket.</li><li>Figure 5 in the front view of a detail of an attachment to a housing with inclined side surfaces.</li></ul>

p0007Figures 1 and 2 show a screen housing (1) without a keyboard in front view and plan. placed on the housing (1) a pivot bearing plate (2) with longitudinal guides (3) in which the movable support arms (4) is set to the respective housing width and are clamped by means of fastening screws (5) to the slotted longitudinal guides (3) for example. The fixing to the housing can take place for example with screws (6) and the rubber buffers (7) or similar elements. The fulcrum bearing plate (2) has two grooves (8), which serve as guide for the laterally displaceable turning and fastening pins with nuts (9) of the rotary arm (10). The rotary arm (10) has to change its rotational radius, for example, a slot (11). The rotary arm (10) may be divided, connected for example by a universally movable joint (12) whereby the inclination angle of the tray (13) changes and this can be finely aligned even after positioning. The holder (14) of the tray (13) has a pivot point (15) and a circular groove (16). The plate (13) can thus about the pivot point (15) is rotated for adjustment, and in the circular groove (16) are locked with bolts and nuts (17,18). The altitude of the plate (13) may for example be leveled in the slot guide (19) of the holder (14).

p00083 shows the device in side view in the version with floor support. This variant is of the width of the housing (1) independently and therefore does not require carrying arms, but a length and height adjustable bracket means (20), which serves as a connection between the pivot bearing plate (2) and the bottom bracket (21). Will not the device equipping with a floor support and extended bracket means, such as may as dotted lines a clamping ferrule (22) take their place. At sufficiently stable implementation of the bracket means (20) the pivot bearing plate (2) can also be above the terminal housing (1), be located without physical contact with the same.

p0009Figure 4 shows a front view of the device with the terminal housing (1) in a further variant by the bracket means (23) laterally beneath the housing (1) is guided.

p0010Figure 5 shows the attachment of the supporting arm (4) on the terminal housing (1) with sloping side faces (25). As support point for the screw (26) for example is a bonded to the side surface of the rubber buffer (27).
