Definitions

  • the present invention relates to a method for driving a movable furniture part having the features of the preamble of claim 1.
  • the object of the invention is to provide a method for driving a movable furniture part, in which these disadvantages are avoided.
  • the predetermined value of the force is therefore selected in a first variant, that at this value just the movement of the movable furniture part inhibiting forces, such as friction, are compensated and thereby a constant speed of the movable furniture part is effected ,
  • the movable furniture part therefore seems to be stored without friction.
  • the drive unit can be speed-controlled on this section of the total distance traveled by the movable furniture part.
  • This may be, for example, one of the closed and / or the open end position of the movable furniture part upstream partial section. In this case, therefore, the acceleration and / or deceleration of the movable furniture part in the vicinity of the end positions would be speed-controlled.
  • the speed of the movable furniture part reached after the initial acceleration phase has been completed should be so low that at this speed the damage resulting from a collision is minimal or zero.
  • the achieved after completion of the initial acceleration phase speed of the movable furniture part is thus maintained as long as no external intervention by a user or a collision occurs.
  • the impression of a non-driven movable furniture part is awakened, although the drive unit is still active.
  • This electronic disengagement of the drive unit achieves both a simple operability of the movable furniture part and an improvement in safety:
  • the user can determine the speed desired by him by manual application of force (for example tension or pressure) on the movable furniture part. He is not bound to a given choice, but can choose any speed. Of course, it can be provided to specify a maximum selectable speed, ie to cover the selection of possible speeds for safety reasons.
  • the force exerted by the drive unit is less than the restraining forces - preferably zero Newton (N) -, the movable furniture part so determined by a difference between the driving force and inhibiting forces and its mass Route comes to a halt. To accelerate the movable furniture part then the user must be manually engaged.
  • the regulation of the force to the predetermined value by controlling the current supplied to the drive unit, wherein the current is determined by controlling the voltage applied to the drive unit terminal voltage.
  • the collision detection could be realized as follows:
  • the momentary increase in the current caused by the collision is detected by the control circuit, which then regulates the current intensity. This is done by lowering the terminal voltage. If the terminal voltage falls below a predetermined or specifiable value, this is detected as a collision. Now suitable measures, such as the braking of the movable furniture part can be made.
  • the collision detection can be done for example by monitoring the speed of the movable furniture part or the measurement of the drive unit supplied current or the electrical voltage. For example, an increase in the current supplied to the drive unit could be detected, which is due to the forces which occur between the movable furniture part and the collision object, which the drive unit seeks to overcome. It could also be monitored a drop in the terminal voltage of the drive unit, which is due to the fact that the speed of the movable furniture part and thus the voltage in collision drops suddenly.
  • the force to be exerted by the drive unit to overcome the forces inhibiting the movement of the movable furniture part can be determined by moving the movable furniture part over a short distance, for example 15 millimeters Moves a constant speed and the required force is determined.
  • the determination of the current required for a constant speed can also be such that the movable furniture part speed-controlled to this speed is accelerated and when reaching the speed of the present at this time current is measured.
  • the thus determined current intensity of the drive unit for example, by specifying a suitable terminal voltage, the drive unit supplied.
  • the predetermined value of the force exerted by the drive unit causes an acceleration of the movable furniture part. This would be especially advantageous for long time to be covered by the movable furniture part ways to shorten the time required. If the resulting acceleration is not too great, the impression of a non-driven piece of furniture is still almost created. In any case, the advantageous safety aspects are fully preserved.
  • the determination of the force takes place directly in the drive unit.
  • This may be, for example, a measurement of the current supplied to the drive unit, which is directly proportional to the torque exerted by the drive unit. This is in a known manner with the force exerted on the movable furniture part in connection.
  • I is the current supplied to the drive unit
  • r is the reduction ratio of the transmission
  • C is an engine constant.
  • the determination of the force exerted by the drive unit on the movable furniture part force can also be done by a mechanical force sensor or by a mechanical torque sensor. If the determination of the force is provided by a current measuring device, this need not of course be arranged in the drive unit.
  • Fig. 1 shows in schematic form a furniture 1 with a plurality of movable furniture parts 2, wherein the uppermost movable furniture part 2 is shown extended.
  • a drive unit 3 which is an electric motor in this embodiment, as well as a roller 9 and a toothed belt 10 guided thereover, can be seen.
