Definitions

  • the present invention relates to a drive for a movable furniture part, comprising a motor and a driven by the motor output for the movable furniture part.
  • the object of the invention is therefore to provide a generic drive, which allows an undisturbed manual operation of the movable furniture part in the event of a motor failure.
  • an activated clutch is understood to mean a clutch which is in a state in which it transmits forces between the engine and the output, so that there is an uninterrupted power train between the engine and the output.
  • a disconnected clutch is understood to mean a clutch that is in a state in which no forces are transmitted between the engine and the output, so that the power train between the engine and the output is interrupted.
  • An engaged clutch may also be referred to as a closed clutch and an off clutch as an open clutch.
  • the switchable coupling provided according to the invention makes it possible to separate a defective engine by switching off the clutch from the output, so that no escapement from the engine to the output and thus to the movable furniture part can be transmitted. As a result, an undisturbed manual operation of the movable furniture part is possible.
  • the coupling is designed such that it can be switched on and off by a control or regulating device.
  • this can be Embodiment by the ability to control the clutch in normal operation, ie without the presence of a motor defect, to be implemented or a plurality of other functions.
  • the coupling can be designed such that the strength of the coupling force is variable.
  • the amount of power transmitted from the engine to the output can thereby be changed.
  • This makes it possible, for example, to realize a smooth start-up of the movable furniture part by setting the clutch in such a way that when starting the engine a slight spin (similar to the grinding of the clutch when starting a car) takes place.
  • This function can be realized, for example, in a frictionally engaged coupling.
  • the coupling is designed such that the change in the coupling force at the transitions between the off state and the on state along a predetermined profile. This makes it possible to realize different starting behavior with a single motor, which, moreover, does not have to have any other functions than on and off.
  • the coupling may for example also be designed as an electromagnetic clutch. Such a coupling may further be designed such that it is switched off in the de-energized state. As a result, it is ensured in the event of a power failure that the motor can not resist any manual operation of the movable furniture part.
  • a measuring device for detecting the position and / or movement variables such as speed or acceleration of the movable furniture part.
  • This makes it possible, for example, to control or regulate the shiftable clutch as a function of the measured variables.
  • the coupling can be switched by the control or regulating device as a function of the measuring signals of the measuring device.
  • control or regulating device is designed such that it turns off the clutch when the movable furniture part is spaced from the furniture body and has a speed which is less than or equal to a predetermined value - preferably zero.
  • the movable furniture part is moved by the motor after an initial release by a user in a position between the closed end position in or on the furniture body and the fully open end position. This partial opening may be sufficient for the removal of or for filling with contents.
  • the initial triggering can be done in various ways, for example via the operation of a push-button or by pulling the movable furniture part.
  • control or regulating device is designed such that it leaves open the clutch in a further manual movement of the movable furniture part in the direction of the fully open end position.
  • the engine serves only as a starting aid to overcome any existing automatic feed, while he can exercise in the above case over the entire opening path forces on the movable furniture part.
  • control or regulating device also uses the motor to assist the closing operation of the movable furniture part.
  • it may have a threshold value with respect to the movement variables of the movable furniture part transmitted by the measuring device, wherein it triggers the driving of the movable furniture part when the threshold value is exceeded.
  • This threshold value can be different for at least two positions of the movable furniture part.
  • control or regulating device triggers the drawing of the movable furniture part from the fully open end position at a lower value of an externally applied to the movable furniture part force as if the movable furniture part in an intermediate position between the closed end position and the fully open end position is located. This is because of a fully open furniture part the intention of the user is unique. On the other hand, if the furniture part is partially open, too low a threshold value could trigger the removal of products.
  • the movable furniture part is accelerated to a predetermined speed value after the release.
  • Is in a furniture in addition to the drive an automatic feed provided, which is designed such that it can move the movable furniture part in the closed end position in or on the furniture body, may preferably be provided that the control or regulating device opens the clutch as soon as the movable furniture part comes in the area of automatic retraction.
  • This is advantageous in that automatic feeders are already present which allow a closing process which is perceived by users to be particularly pleasant.
  • opening the clutch eliminates any influence of the engine, so that the movable furniture part can move alone under the influence of the automatic retraction in the closed end position.
  • a piece of furniture has a collision detection device for the movable furniture part, it may further be provided to configure the control or regulating device such that it switches off the coupling when the collision detection device reports a collision. As a result, damage or injury is avoided by a continuous force of the motor in the event of a collision.
  • the measuring device may, for example, comprise an encoder, whereby both inductive and optical encoders can be used.
  • an encoder is coupled to the output. In this case, a change in position of the movable furniture part is always detected accurately even when the clutch and manual operation.
  • the output can interact for example via a traction means with the movable furniture part.
  • a traction means with the movable furniture part.
  • a cable pull, a toothed belt or the like can be used as traction means.
  • the engine, the clutch and the output are arranged along an imaginary axis, wherein the clutch between the engine and output is arranged. This allows a compact design of the drive, making it easily in the interior of the furniture on the furniture body, for example, between the rear wall of a drawer and the rear wall of the furniture body can be arranged.
  • a particularly simple construction results when it is provided that along the axis between the engine and clutch on the one hand and between the clutch and output on the other hand in each case a shaft is arranged.
  • clutch When switched off, so opened clutch rotates only the output side arranged coupling part in a manual operation of the movable furniture part.
  • the clutch When the clutch is engaged, that is to say closed, the force is exerted by the engine on the output in such a way that the shaft arranged on the motor side drives the output-side shaft via the clutch.
  • the engine interacts with the clutch via a transmission.
  • the engine is designed as an electric motor.
  • the proposed drive is particularly suitable for a designed as a drawer movable furniture part.
  • Protection is further desired for a piece of furniture with a furniture carcass and furniture furniture movably mounted in the furniture body, which is characterized by the arrangement of a drive according to one of the aforementioned embodiments.
