The The invention relates to a device according to the preamble of the claim 1 and a piece of furniture Claim 24.

State of the art

Devices for moving mutually movable furniture parts, wherein a furniture part is moved relative to another furniture part by means of a drive unit and the driven movement of the furniture part is carried out by a driven pivoting movement of an arm, are already known. The international patent application WO 2006/017865 A1 shows, for example, a support member for attachment in a furniture body, wherein on the support member an ejection device for ejecting a movable furniture mounted in the furniture body part is attachable. With regard, in particular, to the reliability or to the maximum possible transmission of force to the furniture part to be moved, the known devices can not be used in the desired manner or are not technically mature.

Purpose and advantages of the invention

task The present invention is a device of the initially called type to provide, which for a variety of applications technically or is economically advantageous or a corresponding Furniture ready to deliver.

These The object is based on the preamble of claim 1 by the claims 1, 7, 9, 13, 14 and 15 or solved by the claim 24. In the dependent claims are advantageous and expedient developments of the invention.

The Invention goes first from a device for moving mutually movable Furniture parts, with a drive unit by means of which a first furniture part relative to a second furniture part driven movable, being one between the furniture parts trained and pivotable with the drive unit arm such is formed that by the pivoting of the arm, the driven Movement of the first furniture part he follows. An essential aspect of the invention is that investment means for temporarily coupling an end portion of the arm with one of furniture components are present during the pivoting movement of the arm. By the investment means according to the invention, which between the pivotable arm and the one cooperating with the arm to moving furniture part act, can be a safe or reliable coupling of the relevant Parts are made possible which usually at least for the pivoting movement of the arm is effective. The once furnished and again detachable Coupling, for example, by exceeding one for the device the coupling state or an associated locking state set up force or only when exceeded solved a counteracting force again. This can be the driven total Movement of the furniture part to be moved reliable accomplish. Furthermore can be comparatively larger forces the pivoting movement of the arm transmitted to the moving furniture part. In particular, it can be avoided that the arm during pivoting on the furniture part to be moved only pressed is bound or undefined or not sufficiently firmly coupled is. possibly occurring in rough use vibrations or forces of Outside on the device or the considered furniture parts, which optionally even only a brief separation of the arm from the furniture part to be moved could cause when pivoting, can be avoided be or for the coupled situation remain without adverse effect.

The Investment funds can among others e.g. a magnetic or Velcro connection or another adhesive bond include.

The proposed arrangement can primarily for a driven ejection movement a closed position of the first furniture part in a partial opened, extended or swung movement are used, with a possible further movement of the first furniture part then to Example can be done by hand.

Especially becomes the arm and the furniture part in contact with the arm not easily decoupled or will only be exceeded decoupled a particular adjustable force value. An e.g. unintentional or comparatively low initiation by a person or an object on the driven furniture part, what in practice can occur again and again, is not critical for a uniform or trouble-free movement of the furniture part to be moved.

in principle can the pivoting arm in an individual case also on the not to be moved second furniture part in particular firmly fixed or possibly also displaceable to a certain extent be arranged. However, it is also conceivable that the arm on the first or moving furniture part is attached and moved with this when pivoting the arm becomes.

If the drive unit attached to the second furniture part, the drive unit, for example, on a furniture back wall z. B. at height a furniture part to be moved, for example, be positioned opposite a drawer rear wall or behind, below or above the drawer.

It is moreover preferred that the investment means a guide assembly for guiding the movement of Having arm in the coupling state. Usually will when pivoting the arm when this is about a positionally fixed axis is pivoted, the end portion of the relevant furniture part moved along a contact area. To be sure of this movement respectively, is a corresponding leadership arrangement advantageous. This can be a precisely executed or uniform movement of the furniture part to be moved will be realized.

Especially it is beneficial that the leadership arrangement is configured such, the end portion of the arm during its pivoting movement continuously respectively. Upon contact of the arm with the moving furniture part can with the guide assembly be achieved, the movement of the moving furniture part evenly and to run continuously. Basically, however, with the leadership arrangement also a stepped or non-uniform movement of the first furniture part can be achieved, e.g. first faster and then slower.

Especially It is advantageous that the guide arrangement a guide rail comprising, at the one coupled to the end portion of the arm carriage is movable. A guide rail with a movable carriage is comparatively space-saving set up and can absorb relatively large forces, causing the Movement of the first furniture part Advantageously possible by the pivoting movement of the arm. It is advantageous if the carriage on the guide rail is secured and in at least two opposite directions is movable.

Becomes the device according to the invention for example, to move a drawer relative to a furniture body used, for example, by lightly pressing against the drawer front or by a short pull on a handle the drawer or by pressing an opening sensor, for example about an opening sensor bar, a Geared motor put into operation and the pivotable arm, for. be turned outward from a pivoted position. The drawer can possibly over the coupling device or the slide or guide rail depending on the length of the Arms from the furniture body one piece be pushed out far. The further opening can be done by hand, for example.

The same principle can also be used for the last part of the closing movement of the drawer by means of the pivotable arm. For example, by sliding the open drawer by hand to the contact, for example, the drawer back with the out in the pivoted position located swivel arm or when touching the drawer with a contact or a sensor initiated the driven closing operation. In this case, the pivoted swivel arm is brought into the coupling state with the drawer and then swung back over the drive unit to its original position, wherein the drawer is moved in its closed position.

to Control or regulation of the movement of the arm can For example, a digital control can be provided with which a Series of different control steps are possible. In principle, in particular during the closing process different security arrangements are set up. For example can over an electronic surveillance of electricity for the drive unit or by detecting a current increase or an elevated one Energy supply just before a closed position of the drawer over a normal value corresponding security steps are initiated. For example, then the drive unit immediately shut down become. Electronic monitoring in particular serves to prevent jamming or injury for one Users of the drawer ready for their driven movement can, for example, can so that bruises and injuries of the hand or fingers avoided become. The example of a drawer can also be transferred to other movable furniture parts, e.g. For doors, Flaps or plate elements.

Further It is advantageous that the investment means a mechanical and / or comprise electrically securable coupling device, which between the arm and the furniture part which can be brought into contact with the arm is working. By appropriate mechanical or electrical safety clutch can be a particularly reliable Coupling between the arm and the relevant furniture part can be achieved. This elevated continue the reliability and functionality the device for moving the considered furniture part.

One Another essential aspect of the invention is that one over the Drive unit rotatably driven spindle for pivoting the arm is provided. A rotary spindle can be comparatively space-saving be used. Furthermore can over the Spindle, which, for example, between the drive unit and a bearing is rotatably mounted, comparatively high forces of the drive unit are transmitted to the pivotable arm. A turning spindle is especially as a standard component in different dimensions or materials available.

Especially Preferably, the spindle is designed as a threaded spindle, along derer a couplable with the arm carriage by the rotational movement of the Threaded spindle is movable. In such an arrangement let comparatively high forces to transfer the arm to be pivoted. It can also be an automatic Securing or an inhibiting mechanism for the pivoting of the arm over the Sled can be realized. The threaded spindle can be different Have external thread, which in particular with a suitably designed accordingly Internal thread on the carriage can interact. To exercise the threaded spindle, for example, the drive unit as electrical, be designed hydraulic or pneumatic motor.

One Another important aspect of the invention is the fact that one over the drive unit powered movable flexible drive organ for pivoting of the arm is present. As a flexible driving element, for example a particular circulating rope or string element, a drive belt or a drive chain into consideration. For example, a flexible Driving member in a simple manner by one of the drive unit rotatably driven drive wheel to be moved, which is spaced apart from one Wheel guided circumferentially is and the drive means a reciprocating motion of the Drive member allows connection in connection component. A movable flexible Propellant is relatively robust and can be comparatively strong Train be charged.

Prefers is the drive organ designed, by its driven movement to move a couplable with the arm slide. It can the movable carriages over a separate leadership unit defined led or be moved by means of the drive member. This arrangement is overall very reliable and simple.

In one moreover preferred embodiment of the subject invention, the carriage is transverse to the direction of movement the first furniture part movable arranged. Leave it for example, the carriage is in an area between the first and second furniture part arrange, which may be relatively narrow or removed from an operating page is and possibly for constructive reasons anyway is present and thus no or almost no additional Space for the carriage or the drive member is needed.

For example let yourself along a back wall a furniture body a drive unit with a flexible drive member, a drive therewith carriage for pivoting the arm and the arm itself in the intermediate area to the back a moving furniture drawer be set up.

advantageously, is the sled over a connecting element with a displaceably arranged on the arm sliding piece connected. The carriage, for example, parallel to the longitudinal direction the drive member are reciprocated, wherein on the carriage a lever projecting at a fixed angle is attached to it, the hinged to a sliding piece attacks. When going Moving the carriage with the lever will also move the sliding piece along moved the arm, the arm imposed the pivoting movement is, for example, a maximum of about 70 to about 90 degrees.

One Another significant aspect of the invention is that the drive unit an electric motor comprising a stator with magnetic coils and a comprising rotor interacting with the stator, on which the arm is trained. This arrangement is particularly space-saving or compact and easy to set up the transfer comparatively high driving forces on the swiveling arm. Otherwise, you can also do this Save necessary gear elements. In particular, none or almost no mechanical components for transmitting the driving force for pivoting of the arm necessary. in principle can thus the swivel arm fixed to a rotor of the electric motor be connected, which as an inner rotor to an outside Stator is formed with a plurality of magnetic coils.

One Another central aspect of the invention is that damping means are provided with which when in contact with a furniture part arm located a movement damping between the arm and the furniture part in contact with the arm possible is. In particular load peaks or damage on the pivotable arm or on the relevant furniture parts and an undesirable one noise to avoid is the motion damping by steaming agents advantageous. The damping agents can be designed in different ways, especially in furniture known damping devices include, for example, fluid damper, spring shock absorber or combined dampers or dampers formed by the material properties of a damping member, for example made of an elastomer.

One additional important aspect of the invention is to be seen in that provided compensation means are, with which in the pivoting movement of the arm, an angular offset between a transmission part of the drive unit and the arm compensated is. For example, damage caused by a brief or slight overrun of the drive unit at in a mechanical investment or end position located pivotable To avoid arm, appropriate balancing means are advantageous. For example, an elastically resilient compensation element be provided, which is the driving effect of the drive unit on the arm absorbs or compensates when the arm is already is in an end position. This can be damaged on the engine, the transmission, the pivoting arm or others Almost exclude components. As compensation means, for example, as a rotation angle compensation acting oblong and flexible member, e.g. a spring steel wire are provided. With the compensating means can ensure an exact end position of the arm be, with a different tracking of the gear motor is compensated after the shutdown pulse, which in speed control the geared motor depending on the given pivoting speed of the arm can occur.

Further It is proposed that the arm is designed so that the first Furniture part over a section driven in standard operation in a direction zurücklegbaren movement path is movable. In general, the pivotable arm is used to first furniture part only about a leg of the total possible Motion range driven to move. This can be for example driven to moving drawers for a first leg from the closed to a partially open position will be the case then afterwards from Hand open the drawer further. For this serves the arm, so to speak as an ejector or as an initialization device.

Prefers the arm is designed such that by pivoting the Arms the first piece of furniture from a closed position to a partially open position is driven driven. This increases in particular the ease of use for that too moving first furniture part, for example a drawer.

So can adjustable or changeable the ejection or if necessary, the pull-in section of the first furniture part are determined. This is possible especially easy by adjusting the arm length of the Realize pivoting arm.

In a preferred embodiment of this device according to the invention, the arm is designed to be driven by pivoting the first furniture part from a partially open position to the closed position to move. In this way, the device according to the invention can be used without additional facilities for a closing movement of the first furniture part, especially if the Mö to be moved is difficult to move by hand, eg in large and heavily loaded drawers and pull-outs. Thus, the ease of use for a user can be further increased. In addition, an exactly adjustable or defined pretend closed position of the first furniture part are made possible by the pivoting arm.

In a particularly useful embodiment The invention relates to a control unit for controlling the drive unit and a switching unit, with which a manual release of a Pivoting movement possible is, so that the arm is driven from a basic position into one Swiveling position arrives. With a control unit, the drive unit safely operated and for a variety of different operating modes are used. With the switching unit, an operator can individually or according to Need the pivoting easily trigger, especially without directly on the furniture part to be moved act.

Prefers the control unit is formed, the arm after pivoting driven from the basic position in the pivoting position in a Basic position back bring to. Depending on the application, it may be advantageous that after the ejection movement of the first furniture part through the arm of this back to its normal position. In this case, the arm is only for an ejection movement used. The closing process can then be done in a known manner, for example, thus a drawer conventional with an automatic retraction with or closed without damping device become.

It But the reverse case is conceivable, according to which the arm only for Pull in or close of the first furniture part is used if this for it e.g. detachable with the arm coupled and the extraction or opening of the first furniture part without drive support e.g. done manually. This means that the arm is e.g. so from the Control unit is checked after removing or opening the first furniture part the arm is brought into a pivoting movement, from which then the Coupling with the first furniture part and its subsequent Pull in or close can be done.

Especially Preferably, the arm is configured by a pivoting movement from the basic position by up to 90 degrees the driven Movement of the first furniture part to enable. This allows almost ideal mechanical lever ratios for the realize driven movement of the first furniture part. moreover is the maximum swept by the arm swivel radius of the arm for the movement of the first furniture part used.

It is over this is preferred that the abutment means rotatably mounted on the arm Roller and / or ball includes. This can be a particularly gentle though reliable Contact between the arm and the arm engageable furniture part will be realized. Preferably, the ball or the roller is rotatable stored, which in their investment state this relative to the corresponding Furniture part on can roll this.

The Invention also relates a piece of furniture a first furniture part, that relative to a second furniture part is movable, in particular driven by a drive unit movable drawer, wherein a guide unit for guiding the first furniture part on the second furniture part is available. The furniture is characterized in that one of the above devices is provided. In this way, the aforementioned advantages can be for the relevant furniture part realize.

One preferred furniture according to the invention draws It is characterized by the fact that several first furniture parts are provided, which each over one of the aforementioned devices are driven driven. In usually furniture with several movable first furniture parts or drawers, for example, used in the kitchen area. advantageously, can all first furniture parts as explained be moved driven.

Finally will proposed that a plurality of drive units are provided, the over each other a rail and / or a cable line are connected. So that can for example about a parent or central control or control unit controls a plurality of drive units become. Advantageously, the drive units are interconnected connected.

To supply a further drive motor 67 is this over a line 68 for example, with the drive motor 66 connected.

For adjustment, programming, inspection or maintenance and the like is a setting display 69 also with the transformer and control unit 61 connected.

Another arrangement according to the 14 to 17 Similar embodiments of a coupling device show the 21 to 24 , A pivotable about a rotation axis S pivot arm 5 has a dome head 44 which is in an annular spring 70 at least temporarily coupled in plant can be brought. The feather 70 is at a dome sled 71 set along a slide rail 72 is movable. The slide rail 72 is for example on a drawer rear wall 2 B attached. On the swivel arm 5 is the circular dome head 44 with conical sidewalls 44a attached. The on the slide rail 72 slidably mounted dome sleds 71 has a circular receiving ring 73 on, in which the annular spring 70 located. The feather 70 has the task, the ejected or to the swivel arm 5 inserted drawer to fix something. After enclosing the dome head 44 through the annular spring 70 , begins, triggered by a contact or sensor of the swivel arm 5 to turn, the entire pivoting movement according to 21 is indicated by the dashed line L2, along which the coupling head 44 emotional. In the course of the pivoting movement, the coupling head becomes 44 increasingly stable in the annular spring 70 anchored and can, for example, draw the drawer.

In the 29 to 32 is an ejection device according to the invention with a swivel arm 5 shown with a rotation angle compensation. In the case of analog or digital speed control of geared motors, the corresponding geared motor runs differently depending on the input of different swivel arm speeds after the switch-off pulse, whereby an exact adjustment of the swivel arm or an end position of the swivel arm is not possible. For a closed position, for example, drawers, however, it is necessary to ensure an exact adjustment. To achieve this, a rotation angle compensation is proposed according to the invention.

On the swivel arm 5 this is an angled or bent spring steel wire 79 firmly connected. The swivel arm 5 is fixed in the area of the axis of rotation S with respect to a drive hub 80 rotatably mounted Schwenkarmnabe 81 connected, with the arm 5 via a geared motor 82 is rotatably driven about the pivot axis S. The fixed on a transmission axis A drive hub 80 is with the angled end of the spring steel wire 79 connected. The movement of the drive hub 80 on the arm 5 thus takes place over the spring steel wire 79 , At the swivel arm hub 80 are also two opposing Begren Zung strokes 83 . 84 provided, depending on the pivot position of the arm 5 or the drive hub 80 the spring steel wire 79 can be present. There are also fixed stops 85 . 86 for limiting the pivoting movement of the swivel arm 5 educated. This can be done when the swivel arm 5 the exact position on one of the fixed stops 85 . 86 has reached, the transmission axis A and the drive hub 80 turn a little further, with the swivel arm 5 can remain in its fixed end position and the further rotation of the drive hub 80 by a self-resetting relative movement of the drive hub 80 opposite the arm 5 is compensated. The further rotation of the drive hub 80 is caused by the bent spring steel wire 79 allows. Such a situation is for example in 31 shown, wherein the swivel arm 5 from according to 29 reached final position on the fixed stop 85 by a piecewise advancing or further rotation of the drive hub 80 Here, for example, about 25 degrees in the in 31 shown position reached.

32 shows the swivel arm 5 in the on the fix stop 86 reached Endschwenkstellung without a tracking position of the drive hub 80 ,
