Since these operations törers sit at the computer terminal hour after hour and day after the day, neck and / or shoulder problems soon appear. for the operator.

Furthermore, the placement of the documents on a horizontal count table top, ter, which are listed at the top of the document, are inclined that the operator, when reading the data forward to perceive the data correctly. This suggests, that the operator in addition to monotonous twists of the neck and lateral shoulder portion also exhibits rocking motions in a direction perpendicular to the above.

There are devices on the market for supporting such that forms do not need to be placed on the table top at a certain stand from the keyboard. However, it has been found that these devices work poorly in practice. Usually is working materials, ie. so for example the pile of these devices are attached to one of the ter. A device is made up of two consecutive ones curved and rotatably mounted tubes and at one end of which a anbragd. This is fixed in does not interfere However involves the placement of a pile of forms several kilograms heavy document disk is device the table edge and on the table surface. on the document board, that the lever principle more or less makes it impossible to use the device successfully. The for the stresses on the storage devices become too great. the large weight at the end of the device leads i.a. 10 15 20 25 3 455 065 Disclosure of the invention Technical problem From a work environment point of view, it is ideal for the operator to turn the neck and shoulder portion as little as possible and to also otherwise be allowed to sit as still as possible during handling the document.

Solution The above requirements are met by the present invention, relating to a device for carrying work material to applied to a keyboard connected to a computer terminal, characterized in that it includes one close to the keyboard adjustable elongate stand, which is made up of a lower part, to be applied to a base and an upper part comprising two opposing elements, along which a plate shape is displaceably arranged and at the top of which a preferably rotatable and preferably raising and lowering adjustable means is connected and at the top of which one sheet material, with a spread adapted to the working material, is directly or indirectly attached.

The lower part of the stand may have such a width that an over- sliding weight on the disc material, for example in the form of a pile of forms, without problems is carried. However, it is preferred that that the width of the stand is relatively small and that a good stability is achieved by means of support plates, which are attached to the stand and forms a certain angle with the stand, preferably show a right angle. It is preferred that the support plates be correctly mounted at both ends of the stand 1 milled groove 1 the lower part of the stand. The support plates are directed from the stand and ate the same hob as the spread of the disc material.

However, it is possible to waive one or more of these functions in case the device is adapted from the beginning to a special and common in the market keyboard. The adjusting means is as indicated above preferred wise so constructed that the disc material and what was placed on it the working material can be raised and lowered as well as rotated. Juste- ring means of varying type can be used. An example of an adjusting member is a height-adjustable ball joint with hearing stop screw for reading the adjusting means. in a specific location.

According to the adjusting means only rotatable in the plane of the platform. This enables a robust and reliable design of devices a preferred embodiment of the invention is according to the invention.

For example, such an adjusting member is made up of one inner part permanently attached to the upper side of the platform of a circular washer resting on the platform and one on top tray placed tubular member and an outer part enclosing the tubular member consisting of an inner tubular member bushing and an adjustable outer tubular member provided with an inlet and screw device placed therein possible locking of the outer tubular member in certain height and side position and at which tubular member the disc the material is directly or indirectly attached.

The adjusting member is attached to a platform as easily as possible can be slid along the stand for a placement 1 ratio to the keyboard according to the Platform covers the upper part of the top of the stand and partly encloses them to the platform has a substantially square or a substantially the operator's wish. two opposing elements on the stand. It is preferred that 10 15 20 25 30 5,455 us rectangular spread. At least in the corner of the platform wires, bearing means are arranged running along the opposite side of the frame. standing element. This means that the platform exhibits at least four bearing members. If you want even better stability of the platform, the bearing members can be extended, for example to six pieces. of which two placed on the middle of the platform 1 longitudinal joint counted. It is preferred that bare fitted wheels.

According to a preferred embodiment of the invention, that the bearing means consist of rotating the upper part of the stand, along which the platform runs, a angle with the substrate, which is essentially the same as the slope the top of the keyboard in relation to the made.

Benefits The advantages of the device according to the invention are several.

First, it is easy to apply to the keyboard.

By letting the stand and support plates rest against the working the table without fastening devices, the operator can agree on how the working material is placed in relation to gentbordet. Because the stand in cross section has one and the same design allows the user to determine the length of the stand, which fits in the individual case. By delivery- at the same time, the desired stand length can be cut and wide Both ends of the stand are milled out grooves for application of the support the plates. Further with ease of movement from one work table to another. You do not need to unload any fastener. carrying the working material, with ease can the device By the disc, hot can be moved 1 sideways, ie. can be adjusted in height and at a certain angle to the along the stand, and (or the stand) the user has great freedom to In those cases was used gentbordet place the work material within easy reach. when essentially numbers are to be entered into the computer 10 15 20 25 30 455 065 e usually only a limited part of the keyboard and at using the device according to the invention, the disc can pushed in over the keyboard so, Thereby, the user essentially needs that only the numeric are free. do not turn your head and problems with wear and tear in the throat. neck and shoulder area are avoided.

If the disc of the device according to the invention is allowed tilt at essentially the same angle as the angle present tvâ secondly, the user does not have to lean forward for between the top of the keyboard and the base is achieved benefits. to read the information at the top of the documents and can the disc is placed as low as possible in relation to the i.e. Thereby the gent table, in the immediate vicinity of the keys. the difference in height between the operator's two arms is minimized during work. which is useful for the purpose of preventing damage.

Figure 2 shows a cross section of the device according to the finding through A-A in Figure 1.

Best embodiment Figure 1 shows an embodiment of the device according to the invention as a unit seen from above. The device is stands of a stand 1 with support plates 2 and 3. The displacement on which any type of form 1 a just along the stand a disc 4 is attached, the working material, for example large amount. but the stand l is usually placed so, Figure 1 does not show a keyboard, that its inner edge 5 is located near the keyboard against the computer screen edge, computer screen and keyboard. placed. wetting i.e. the stand 1 is usually placed between 10 15 20 25 30 v 455 065 How the device according to figure 1 is built in detail is shown in Figure 2, which shows a cross section of the device through A-A. The stand 1 is made up of a lower part 6 and a upper part 7 comprising two opposite elements 8 and 9.

Along these elements runs a platform 10. This platform may have a rectangular distribution, such as with dashed lines The corners of the platform have rotating wheels affixed. namely the wheel ll rotating about the shaft 12 and the wheel 13 rotating about the shaft 14. At the top of the platform 10 there is a circular adjustment shown in Figure 1.

Figure 2 shows two wheels, ring means 15 fitted. holder 16 attached. In this holder the disc 4 is inserted and fixed. At the lower edge of the disc 4, a stop strip 18 is attached.

The adjusting member 15 is attached to the platform 10 with of which the screw 19 is shown in Figure 2.

At the adjusting means 15 is a for example two screws, The adjusting means 15 consists of an inner and an outer part. The the inner part is made up of a circular washer 20 and a tubular It is this inner part of the circular attached to the platform 10, formal body 21. the adjusting means 15, which is by means of, for example, two the member 21 has a circular bushing 22 applied. Utanpâ screws 19. On the outside of the tubular the bushing 22 has a second tubular member 23 applied To this tubular member 23 the holder 16 is attached, two of which are shown in FIG. rat. for example by means of three screws 17, clean. In the tubular member 23 a heel is drilled and the goods at the periphery of the hole are provided with threads fitting to a screw device 24.

The outer tubular member 23 with pendant screw device 24, holder 16 and disc 4 are partly movable in height joint in relation to the bushing 22 and partly it is possible rotating the outer tubular member 23 about said bus. ning. When the user has set the appropriate height of the disc 4 in relation to the keyboard and the appropriate angle of the dial 455 065 8 10 15 20 25 30 4 in relation to the frame 1 (in figure 1 this is the angle 90 °), tighten the screw device 24 so that its end lies strongly against the bushing 22. which leads to the disc 4 is locked in the intended position. On: man to a specific keyboard desires a certain height of the device according to the invention is it is also possible to lift off the outer tubular member 23 with attached devices and place a spacer sleeve with a suitable height on top of the outward-facing heel, which the transition 22 passes in at its lower part and then place the outer tubular member 23 on top and resting against said spacer sleeve. In that case, the screw device was used 24 only to retain the disc 4 at the intended angle in the holding to the stem / s 1. i In the device shown in Figures 1 and 2, they have opposite elements 8 and 9 included in the upper part of the frame 7 an angle with respect to the horizontal plane. as in is essentially adapted to the angle of a keyboard above page. However, it is entirely possible by changing the vets profile decrease or increase said angle. For example, can to design the profile of the stand so that the disc 4 becomes complete parallel to the horizontal plane. However, it is preferred in FIG. pure 2 showed the angle.

As previously stated, it is also preferred that the stand l and the support plates 2 and 3 rest freely against the ground, e.g. pelvis a table top. However, it is possible to attach only the stand 1 or the stand with the support plates 2 and 3 at the substrate by any fastening device and by folding down in the table top.

As for the profile of the stand 1, it can be varied.

For example, the lower part of the stand does not have to have lugs, as shown in Figure 2, but it may be planar. In both the cases can advantageously be any material with a certain elasticity and high friction is attached under the lower part 6 of the stand. : ß 10 15 9 455 065 Figure 2 shows how the disc material 4 is indirect attached to the adjusting means 15 by means of the holder 16. A such a holder is not necessary, but the sheet material 4 can attached directly to the adjusting member 15 or to another type of adjusting means.

The device according to the invention can be manufactured from any suitable material including both metal as plastic. The stand 1, the support plates 2 and 3, the platform 10, the two tubular members 21 and 23 and the holder 16 can Brickan 20 and bus 22 can advantageously be made of plastic. Nylon is suitable as material for the bearing wheels ll and 13, while the axles 12 and 14 are made of metal. The disc 4 can be made of any material with sufficient strength and durability hot, for example of acrylic glass. of aluminum.
