Definitions
- the invention relates to an adjustable table for a computer system with a keyboard and a monitor, the table having a telescopic column carrying a table top with a static part and a movable part and a height adjustment of the table top by a relative movement of the movable part of the telescopic column to the static Part of the telescopic column is done.
- the tables are usually height-adjustable or a total of one Longitudinal axis are inclined, however, they have the disadvantage that the angle of inclination of the head of a user changes when the height of the table top of the tables are changed for users of different body sizes.
- the object of the invention is to create a table in which there is the possibility of a predetermined angle of inclination of the head of a user when looking at the monitor regardless of a given height of the table top of the table and thus regardless of the size of a user of the computer. System.
- this object is achieved in that the monitor is mounted on a platform connected to the table top, which is pivotable about a tilt axis that runs parallel to the front edge of the table top, with a change in the pivoting angle of the platform with respect the table top takes place with a height adjustment of the table top via a cable which is mounted in reaction to a relative movement of the movable part of the telescopic column to the static part of the telescopic column.
- the feature that the monitor is mounted on a platform connected to the table top, which can be pivoted about a tilting axis, is parallel to the front edge of the table top
- a change in the pivoting angle of the platform with respect to the table top takes place with a height adjustment of the table top via a cable pull, which is reacted to a relative movement of the movable part of the telescopic column to the static part of the telescopic column, that a table is created in which with a height adjustment of the table top, which always takes place with a relative movement of the movable part of the telescopic column to the static part of the telescopic column, by coupling the cable with the static part on the one hand and with the platform connected to the movable part of the telescopic column via the table top with a height adjustment of the table top and thus the monitor platform, a pivoting of the monitor platform about its tilting axis is automatically brought about by such an angle that the angle of inclination of a user on the
- one end of the cable pull is firmly connected to the static part of the telescopic column, and the other end of the cable pull is coupled to the platform, in particular by means of rollers with a part of the
- the Cable of the table according to the invention preferably contains a pulley. It is thereby achieved that a desired change in the inclination angle of the monitor platform can also take place over very large differences in height of the table top of the table according to the invention.
- the pulley has a transmission ratio of 1:10.
- one end of the cable is connected to the static part of the telescopic column via a deflection roller. It is thereby achieved that a predetermined change in height of the table top causes a change in the deflection of the cable of the cable corresponding to twice the distance of this difference in height, and thus a disproportionate change in the pivoting angle of the monitor platform.
- this feature means that
- a pulley provided in this embodiment of the computer table according to the invention accordingly has a transmission ratio of 1: 5.
- the other end of the cable is preferably connected to a leg which is attached to the monitor platform.
- the leg is preferably connected to the tilt axis of the monitor plate. This ensures that a A change in the pivoting angle can be brought about by changing the pivoting angle of the leg, the leg being shaped and dimensioned such that that one of its ends which is connected to the other end of the cable can be provided in the vicinity of the cable, so that the cable of the cable can be made shorter accordingly.
- the pulley block is preferably provided with a cover in order to protect it from dirt and dust and, on the other hand, to prevent accidental moving objects from reaching its vicinity, which can restrict the mobility of its parts and thus its function.
- a veneer is also advantageous from the point of view of personal protection.
- the monitor platform of the computer table according to the invention is preferably mounted below the surface of the table top. This allows an ergonomically favorable angle of inclination of the head of a user to the image surface of the monitor to be achieved with a height adjustment of the tabletop, which is advantageous for writing documents on the tabletop and for operating a keyboard arranged on the tabletop.
- Computer table is preferably in the range of one
- the telescopic column of the computer table according to the invention is oriented vertically. According to a preferred embodiment of the computer table according to the invention, however, the telescopic column is inclined at an angle of 10 ° to 14 ° in the direction of a user of the computer table. This ensures that in addition to a constant angle of inclination of the head of users of different sizes of the computer table, there is also a constant distance between the eyes of a user and the image surface of the monitor of the computer system for users of different sizes.
- the cable pull is guided over rollers which are provided on a carrier device connected to the movable part of the telescopic column.
- the support device provided on the movable part in which in particular a deflection roller of the cable can be fastened, makes it particularly effective and metered further coupling of the cable with the moving part of the telescopic column.
- Fig.l an embodiment of the computer table according to the invention in the extended state of the telescopic column, in a side view;
- FIG. 2 shows the embodiment of the computer table according to the invention shown in FIG. 1 in a retracted state of the telescopic column, in a side view.
- a table top 11 is connected to a base part 16 via a telescopic column 12, which has a static part 14 and a movable part 13.
- a height adjustment of the table top 11 is achieved in the computer table 10 according to the invention in that the movable part 13 is moved out of the fixed part 14 or is driven into it via a motor (not shown) which can be activated via an activation device (not shown).
- the telescopic column 12 is inclined at an angle of 9 ° in the direction of a user of the computer table, who is located to the right of the column 12 in the illustration shown in the figures. Due to the setting angle of 10 ° to 14 ° of the telescopic column 12, the motor driving the telescopic column 12 is activated at one Movement of the table top 11 towards the user.
- the keyboard of a computer system is arranged on the table top 11 and the monitor of the computer system on a monitor platform pivotally mounted about a pivot axis 20
- a leg 24 is fastened so that the pivot axis 21 can be rotated via the leg 24 and the platform 20 by actuating the
- Leg 24 is pivotable in different angular positions with respect to the table top 11.
- a cable 31 is provided between the end of the leg 24 remote from the pivot axis 21 and the upper end 34 of the static part 14, which contains a pulley 30.
- the cable 31 is guided around a deflection roller 33 which is provided at the lower end of a carrier device 32 which is connected to the movable part 13 of the telescopic column 12 via a holding element 35.
- the part of the cable pull 31 located above the pulley 30 is guided over a roller 36, which is also fastened to the carrier device 32.
- the block and tackle 30 has a transmission ratio of 1: 5.
- lowering the table top 11 causes a change of the angle that the platform 20 makes in relation to the plate 11 in such a way that this angle decreases.
- increasing the table top 11 by moving the movable part 13 of the telescopic column 12 out of the static part 14 of the telescopic column 12 causes the angle that the platform 20 makes with respect to the table top 11 to be increased in a predetermined manner so that it is always ergonomic optimal angle of inclination of the head of a user of the computer system, not shown, is given with respect to the screen area of the monitor mounted on the platform 20.
