Description

Device for moving a furniture part with a

Drive unit and furniture "

State of the art

Arrangements or devices for moving a on a body on guide means movably received furniture part such as furniture flaps, furniture doors or

Furniture drawers are known. In this case, a drive unit for the driven movement of the movable furniture part relative to the furniture body is used, wherein by means of a

Coupling arrangement, the drive unit or one of

Drive unit associated component with a

movable furniture part associated component in one

engaged state can be brought, thereby enabling a driving effect on the movable furniture part is transferable. If no coupled state is given or the coupled state is released or disengaged, there is no transfer of the drive effect from the drive unit to the movable furniture part to be driven.

For the operation of the device, a control unit with, for example, a computer or computer, for example, a control or regulating unit is provided, which detects the presence of a command to drive the movable furniture part with the drive unit and as a result, a

driven movement of the movable furniture part takes place. Of the

CONFIRMATION COPY Command for driving the movable furniture part can from the outside, for example, by a user by pressing a

Actuator be triggered.

Purpose and advantages of the invention

Object of the present invention is, starting from

Devices of the type mentioned in the introduction

 To expand operating options of the devices in an advantageous manner or to improve furniture with such devices accordingly.

This object is solved by the independent claims.

The dependent claims relate to advantageous

Further developments of the invention.

The invention relates to a device for moving a movable on a furniture body via guide means

recorded furniture part with a drive unit for

driven movement of the movable furniture part relative to the furniture body and with a coupling arrangement with which the drive unit and the movable furniture part can be brought together in a coupled state in which a

Transmission of a drive action from the drive unit to the movable furniture part is possible or in one

disengaged state can be brought, wherein the operation of the device, a control unit is provided which detects a drive command from the outside to trigger a driven movement of the movable furniture part, so that in the sequence, the driven movement of the movable furniture part.

The guide means may be, for example, a hinge arrangement or a rail or pull-out guide.

The essence of the invention is that the control unit is designed such that the drive unit and the movable furniture part are engaged with each other via the coupling arrangement when moving and / or holding the movable furniture part via the drive unit is carried out and otherwise disengaged. This advantageously makes a clear distinction between an operating situation in which the movable furniture part is driven or kept driven by the drive unit or is intended to be driven and such operating states, where this is precisely not the case. In that not with the drive unit

connected or engaged case, the movable

Furniture part in particular stand still or, for example, be moved manually.

A holding of the movable furniture part under the effect of

Drive unit with engaged state is so too

understand that the movable furniture part is always very

briefly experiences a driving force or alternately the drive effect is immediately interrupted again and / or possibly reversing the direction of the drive effect. The movable furniture part is thus driven so to speak by an infinitesimal amount, but it does not find any by a

Observer noticeable movement of the furniture part instead, since the furniture part immediately afterwards moved back to the infinitesimal amount, the furniture part is kept "suspended" so to speak. The holding takes place in particular at a vorgebaren Ausfahr- or movement position of the movable furniture part relative to the furniture body. Thus, a furniture part can be held in a position that could not be kept without being affected by the drive unit, for example due to the weight of the furniture part, if no other holding forces are present.

It is also proposed that the guide means for

Motion control of the movable furniture part relative to

Furniture body are designed such that a movement of the movable furniture part by manual action from the outside on the movable furniture part in the disengaged state between the drive unit and the movable furniture part is possible. The guide means thus fulfill the function, a defined or guided movement of the movable furniture part

allow, regardless of whether the movable furniture part and the drive unit are engaged with each other or decoupled from each other.

Thus it is in the disengaged state between the

Drive unit and the movable furniture part without compromises possible to move the movable furniture part manually on the guide means or manually by a person. The manual movement can be carried out in particular both in the opening direction and in the closing direction.

The guide means may be configured as a hinge arrangement for a pivoting movement of the movable furniture part, or as a rail guide or extract for a translational or rectilinear movement of the furniture part.

It is also advantageous that the control unit

is formed, depending on an energy supply for the drive unit for moving and / or holding the movable furniture part via the drive unit a predetermined

Coupling state between the drive unit and the

to arrange movable furniture part. Thus, depending on the energy supply for the drive unit, for example, depending on an energization of an electric drive or a drive motor, a desired coupling state are linked to it. Possible coupling conditions are z. B.

"engaged" or "disengaged" or even a quick or sustained change between these two states.

It is also proposed that the control unit be so

is formed, that arrive with a supply of the drive unit with energy, the drive unit and the movable furniture part in the engaged state. Advantageously, coupled with an energy supply of the drive unit is a coupled state. Thus, whenever a drive effect is to be transmitted from the drive unit, including a power supply of the drive unit

is necessary, set the engaged state. Vice versa it is so that there is a disengaged state when there is no energy supply.

This link usually makes sense if the

Power supply of the drive unit is not permanently pending, but is turned on and off, which may be off

safety reasons may be the case.

A load or stress of z. B.

Coupling components for long periods by the

engaged state when no disengagement would take place is advantageously by the proposed

Arrangement reduced.

The concept of energy is comprehensively understood, according to which

for example, for not powered by electrical energy drive unit en, or for z. B. in working with hydraulic or pneumatic power drive unit en the

Power supply according to hydraulic or

is pneumatic nature.

In an advantageous modification, the

 Coupling arrangement a mechanical coupling. A mechanical coupling is robust and economically advantageous

feasible.

Further, it is advantageous that the clutch assembly

Clamping means for a clamping connection of each other in the engaged state of the drive unit with the movable furniture part to be joined parts. A clamp connection is reliable and can be set up automatically, if necessary.

In a further preferred embodiment of the

Subject matter of the invention, the coupling arrangement is designed to selectively connect a driven part associated with the drive unit and a drive part assigned to the movable furniture part or to separate them from one another.

For example, this can be assigned to the drive unit

Stripping part comprise a shaft end of a drive motor, the - Is set in rotation during operation or when energizing the drive motor in rotation. The output part of the drive unit

associated with a countershaft portion may be present, which is connectable to the shaft end of the drive motor, wherein the counter shaft portion is associated with the movable furniture part. In particular, the shaft end and the counter shaft section can be connected to one another in this way,

in particular via the mechanical coupling, that with the coupled state and rotation of the countershaft portion of the furniture part, the furniture part driven by means of the guide means is movable.

It is particularly preferred if the drive unit comprises an electric motor, via the control unit

is controllable.

Electric motors are particularly reliable and standard as a drive unit in a wide variety of variations

available .

The invention also relates to a piece of furniture with an over

Guide means movably received on a furniture body furniture part, in particular a furniture flap, a furniture door or a furniture drawer, wherein the movable furniture part with a drive unit is driven relative to the furniture body movable, according to the invention one of the aforementioned

Devices is provided. This can be at one

Furniture, for example on a kitchen furniture with a

Furniture carcass in which a plurality of drawers or flaps are arranged and driven by a drive unit are movable, achieve the above-mentioned advantages.
