Definitions

  • Control device for the position of a screen, a keyboard and / or a mouse pad depending on the seating position
  • the invention relates to a control device for the position of a screen based on the seating position of a keyboard and / or a mouse pad, which is preferably used at screen workplaces.
  • an optimal screen arrangement is guaranteed if the visual axis of the employee hits the center of the screen surface perpendicularly and the screen distance is in a range of around 60 cm with a 12-point font size.
  • the natural visual axis When sitting upright (backrest is perpendicular to the floor), the natural visual axis is inclined by approx. 30 to 40 ° with respect to the horizontal, as can be seen in FIG. 1. If the backrest inclination of the work chair is changed by a certain angle, the natural inclination of the visual axis changes by approximately the same angle with respect to the horizontal. The consequence of this is that the screen height, the screen tilt and the screen distance have to be adjusted.
  • the adjustment must also be guaranteed if the workplaces are used alternately by people with different body sizes (e.g. eye level when sitting).
  • actuators using stepper motors or known servo drives are used which are able to move screens in at least one axial direction, so that when adjusted in the horizontal direction , the distance of the eyes from the screen surface can be adjusted, and the height of the screen can be adjusted to the eye height when adjusted in the vertical direction.
  • the position of the screen or the other additional devices is set as a function of signals from a sensor which can be arranged on the backrest of a piece of seating on which the user has taken a seat.
  • the sensor detects the inclination of the backrest and sends its signals to an evaluation and control unit which activates the actuator (s) and optimally adjusts the peripheral device in accordance with the inclination of the seat backrest.
  • a sensor can be an inclinometer, for example.
  • a type of sensor can be used that is able to detect the position coordinates of the eyes and use them as an output signal for controlling the actuator.
  • the sensors are connected to transmission devices which transmit the sensor signals to a receiver, which is connected to the evaluation and control unit.
  • transmitters or receivers that emit infrared, ultrasound or electromagnetic waves are preferred. They are able to provide the measured values for the setting of the peripheral devices with sufficient speed and with sufficient accuracy.
  • the evaluation and control unit is advantageously integrated directly into the computer and the receiver is attached to its housing. With this integrated solution, it is possible to utilize the basic computer with all its possibilities also for adjusting the position of the peripheral devices.
  • a memory circuit can be provided which contains data for the basic setting of the devices / work equipment and anthropometric data with which the basic setting can be calculated and with the aid of which when the user of the computer reports, the optimal position for automatically the screen and other devices are adjusted according to the user's body measurements.
  • sensors can also be used as possible sensor types, which determine the distance of the seat or certain predetermined seat parts from the screen, the keyboard or other peripheral devices and whose position is then kept appropriately. If two distance sensors or two receivers, which are arranged at a constant lateral distance from one another, are used, pivoting about the vertical axis can also be achieved if a screen has to be rotated.
  • a rolling device at the foot of the seating furniture in such a way that it can be used like a conventional mouse control.
  • the supplied signal of the ball is not used to control the cursor, but rather it supplies a position signal of the seating furniture in dependence on the position of the device to be set up. If the seating furniture is moved in any direction, it is generated in the rolling device contained ball a corresponding signal, which - as already described - is given to the evaluation and control unit via a transmitter and leads to the motorized actuator being activated accordingly and thereby, for example, not only tilting and shifting the screen, but also ver ⁇ can be pivoted.
  • the evaluation and control unit is also connected to a further sensor, the signals of which correspond to the set value of the motorized actuator, which reproduces the position or position in which the corresponding peripheral device is located in order to compare, whether a correction of the setting in accordance with the other measured signal is necessary.
  • the evaluation and control unit is also to be designed in such a way that a certain inertia is guaranteed and thus it is excluded that even brief changes in the seating position lead to the actuator being triggered.
  • the delay circuit connected to the evaluation and control unit or the motorized actuator should therefore preferably be designed in such a way that the actuator is only activated after at least 10 seconds after a seated position has been maintained. However, it should also be possible to set the delay time completely variably.
  • a possibility should be provided for the emergency shutdown of the actuator, which prevents damage caused by the initiated adjustment movement of the peripheral device if it hits other objects or limitations.
  • Such emergency shutdown devices can be, for example, overload switches or other circuits using distance or touch sensors.
  • Such a safety device can of course also be the installation of a mechanically effective slip clutch on the actuator. In the case of servo drives, the use of a pressure relief valve for the same purpose is a simple, practical solution.
  • the control device is with flat-panel displays because of its small mass and the correspondingly smaller volume. However, this does not preclude the use of conventional screens with cathode ray tubes.
  • the screen storage table should be designed in such a way that there are cutouts which allow the screen to be pivoted to a much greater extent without the pivoting movement being restricted by the fact that the housing of the screen hits the contact surface of the storage table.
  • Figure 1 is a schematic representation of a user with an optimal setting for the screen of a computer.
  • 2 shows a schematic representation of a screen workstation with a movable and pivotable screen, and
  • Fig. 3 shows another embodiment for moving
  • FIG. 1 shows possible sitting postures of a person at a screen work station.
  • the optimal viewing area for a screen is shown, which changes depending on the sitting position on the screen or also on the keyboard or other peripheral devices that have to be observed or operated. If the user leans back, as shown, the position must be adapted to one another in order to improve the ergonomic conditions.
  • an inclinometer and / or a distance sensor S is attached to the seating furniture 2, the signals of which are preferably transmitted wirelessly, with at least one mini transmitter to at least one receiver (not shown) and from there via a data input of an evaluation and
  • Control unit are fed.
  • a set / actual value comparison of the position setting of the screen 1 is carried out in the evaluation and control unit. For this it is necessary to have the setting of the screen 1 present in the evaluation and control unit. This can be achieved by storing the setting values or by inputting signals from at least one sensor which is arranged on an actuator (also not shown) or directly on the screen 1. If the comparison shows a difference between the target and the actual, depending on the distance or inclination of the backrest of the seating furniture 2, the screen 1 can be shifted or pivoted in the direction of the arrows A, H, N with the aid of the actuating drive.
  • a flat screen 1 is supported on a support 2, to which a receiver E is attached, and can be actuated vertically and by pivoting about the horizontal with the actuator be adapted to the seating position.
  • the device can also be attached directly to the person, for example with a Velcro connection, at a predetermined location on the body. If such an adjustment is not desired, the device can be switched off using a switch.
  • a basic setting can be carried out by entering it in the evaluation and control unit or by calling up stored data.

Abstract

Un régulateur de la position d'un écran de moniteur, d'un clavier et/ou d'un tapis pour souris en fonction de la position de l'utilisateur assis devant l'écran est utilisé de préférence dans des postes de travail sur écran, afin d'adapter la position et l'inclinaison d'appareils raccordés à un ordinateur aux différentes positions que prend un utilisateur assis devant l'écran, ce qui permet de maintenir des conditions de travail ergonomiques favorables. Un moteur de positionnement ajuste au moyen d'une unité d'évaluation et de commande la position de l'écran (1), du clavier et/ou du tapis de la souris en fonction d'au moins un signal généré par un capteur (S) qui représente la position de l'utilisateur assis devant l'écran.
