Description

"Device for controlling movement of a furniture part and furniture with such a device"

State of the art

In the furniture sector, guide means such as partial extracts,

Full extensions or furniture hinges known to move a piece of furniture relative to a furniture body can.

The guide means must meet different requirements, in particular should be made accessible to the movement guide an interior of the furniture body or the movable furniture part to accommodate items in it or to be able to remove it. Furthermore, the guide means must be accommodated to save space.

Purpose and advantages of the invention

Object of the present invention is to provide a guide means for a movable ^■ recorded on a furniture body part furniture improved provide, in particular with regard to compact packaging of the guide means on the furniture and a desired relative movement of the furniture part relative to the

Furniture carcass to access a storage space on the furniture. This object is solved by the independent claims.

In the dependent claims advantageous and expedient developments of the invention are thematized.

The invention relates to a device for

Movement control one on a furniture body movable

accommodated furniture part, wherein the device comprises between the furniture body and the furniture part acting guide means with which the furniture part from a closed state relative to the furniture body, in which the furniture part a maximum zoomed to a front side of the furniture body position moves, in an open state of the furniture part relative to the furniture body brought and again moved back into the closed state. The moved position, for example, a

closed · resp. be pivoted to the furniture body zoom furniture door or furniture flap or a in the furniture body

pushed-in furniture drawer.

A first essential aspect of the invention is that the guide means are adapted to move the furniture part in an opening operation from the closed state such that in a first movement phase of the opening process is a horizontal distance of the furniture part to the front of the

Furniture carcass increases and in a first movement phase subsequent movement phase of the opening process the

Furniture part is linearly movable.

In this way, advantageously, a first

Movement phase, in which a moving away of the furniture part of the furniture carcass front is in the foreground, decoupled from a subsequent or second phase of movement. The following

Movement phase is characterized in particular by a larger or authoritative covered by the furniture part distance compared to a covered in the first movement phase distance of the furniture part. As a rule, the movement patterns or the kinematics of the furniture part of the first and the subsequent movement phase differ significantly from each other. In particular, in the first movement phase, a rotary movement or a pivoting movement of the furniture part may be the determining movement type, whereas in the subsequent movement phase a linear or translatory movement may be the sole or relevant movement. Under the following movement phase, the next or

subsequent movement phase when opening the furniture part to understand.

It is advantageous with the relatively short distance traveled by the furniture part during the first phase of movement of the furniture part in practice a significant area in the

Furniture carcasses inside or in a furniture part interior volume for a user of the furniture accessible. This area can in particular be such that the corresponding movement of the furniture part is often sufficient for the user and therefore subsequently the furniture part is closed again, with a motion sequence opposite to the first movement phase. This case therefore does not concern the subsequent movement with respect to the opening process.

In the first opening movement phase, in particular, a horizontal distance of a furniture front, which is formed by the movable furniture part, enlarged to a front side of the furniture body, wherein the front side of the furniture body, for example, by user-side end faces of side walls of the

Furniture carcass is defined.

In particular, a distance to the front of the

Furniture body facing the back of the furniture part to

Furniture body increases and at the same time so up, or down or laterally added to that a previously hidden in the closed state of the furniture part area on

Furniture carcass now accessible to the user and thus usable. Between the first and the subsequent opening movement phase of the furniture part, the furniture part can stand still or the opening movement runs without stopping and goes seamlessly from the first movement phase in the subsequent movement phase. The first movement phase can be for example a

Include pivoting movement of the furniture part or be determined solely by a pivoting movement of the furniture part. The

Moving the furniture part in the following

Movement phase usually takes place until reaching a maximum opening state of the furniture part relative to

Furniture carcass. ^' The furniture part can in the following

Motion phase alone will perform a linear motion or the linear motion will be over the entire subsequent one

Movement phase or only over a part of the subsequent movement phase of another movement type superimposed.

Overlaying can take place, for example, a partial movement of the furniture part in the direction of the front side of the furniture body by pivoting.

According to an advantageous variant of the invention, the guide means are designed such that in the subsequent movement phase of the opening process with the first

Movement phase reached distance of the furniture part to the front of the furniture body is not or at least not significantly increased. In particular, the distance relative to a significant place on the furniture is not increased. This space saving a necessary minimum distance of the furniture part can be met to other sections of the furniture body. The Mindestabstahd of the furniture part can, for example, by a contour of the furniture projecting control or handle adjacent to the considered movable furniture part

Furniture section be determined, at which at least parts of the furniture part during the opening process, in the first and / or the subsequent movement phase, pass. This

Mindestabstahd the furniture part may be to avoid a

Collision with the above contour on the furniture then not fall below, at least not based on the location of the above contour. Thus, the furniture part can be moved to save space on other sections of the furniture or the furniture body during the opening process of the furniture part,

in particular without an unnecessarily far-reaching movement on the furniture. Another essential aspect of the invention is that the guide means fixed to the furniture body

arranged recording and a movable on it

Include movement element on which the furniture part is added so displaceable that the furniture part of the

Closed state in one to the front of the furniture body

wegbewegte disengagement position and back into the closed state can be brought, wherein in a disengaged position of the furniture part this is displaced by · a displacement of the movement member along the receptacle relative to the furniture body. Again, this is in view of a compact arrangement of

Device and accessibility to a useful volume of the furniture advantageous. The displacement of the moving element relative to the recording can be purely linear or

exclusively non-linear, for example according to a

curved path or there is a displacement with both a linear and a non-linear component. Also, a shift with a superposition of a linear and a non-linear motion is conceivable.

The displacement of the moving element along the receptacle can be done in any disengaged position of the furniture part of the front of the furniture body. During the

Movement of the moving element on the recording can be maintained at the beginning of the shift reached release position or the release position changes during

Move continuously or z. B. on the first and / or last leg of the shift. The distance of the disassembled furniture part to the furniture carcass front can be reduced when moving in particular, but also an enlargement is possible.

The influence of the distance or the disengaged position of the furniture part from the front side of the furniture body during the displacement of the movement element on the receptacle can be formed by the design of a receptacle on the recording

Displacement travel and / or by a simultaneous movement of the furniture part relative to the moving element, for Example in that the furniture part is pivoted on the movement element, which can be done during the sliding operation of the movement element on the recording.

In particular, starting from the closed state of

Furniture part, when an operator pulls on the furniture part, for example, on a handle element manually, in the first

Moving phase only carried out a moving away of the movable furniture part of the front of the furniture body, which is done with the displacement of the furniture part relative to the moving element. The movement element itself remains in particular positionally fixed relative to the recording. Preferably, the furniture part reaches in this first movement phase at the end of a maximum wegbewegte disengaging position of the furniture part to the furniture body front.

Subsequently, with or without a time offset at the end of the first movement phase, when the furniture part is to be opened further, takes place in the subsequent movement phase the

Movement of the moving element on the recording.

But it is also an at least temporarily simultaneous movement of the disengagement movement of the furniture part relative to

Movement element and the sliding movement of the

Movement element along the recording possible, in particular towards the end of the disengagement movement.

An action on the furniture part by an operator can be made via a corresponding control element, for example by means of a handle on an operator side front or

Front of the relevant furniture part.

Advantageously, the furniture part is over a

Pivoting arrangement added displaceably on the moving element. Thus, the furniture part can be moved away from the front, in particular in the first phase of movement and later be moved up to the front again. The displacement movement of the furniture part relative to the moving element, for example, regardless of the movement or position of the Movement element along the recording done. In general, however, control means are formed on the device, with which the displacement movement or the displacement position of the

Furniture part relative to the moving element depends on the

Movement or position of the movement element along the

Recording is determined. The control means may, for. B. include a slotted guide.

With the swivel assembly, a maximum possible

Swivel angle or pivoting of the furniture part relative to the moving element in particular be limited by limiting means.

Alternatively or superimposed to the pivot assembly can also be a different kind of leadership such as a

Linear guide for the movement of the furniture part on

Movement element be realized.

It is also advantageous that the pivoting arrangement a

Lever arrangement comprises. Thus, the furniture part can be guided over an advantageous long life exactly and stably moved, even if the furniture part has a comparatively greater weight.

An alternative advantageous variant of

Subject of the invention is characterized in that the pivot assembly has a four-bar linkage. A

Four-joint arrangement is compact and mechanically stable.

Advantageously, the pivot assembly comprises spring means, which has a spring force for influencing the with the

Pivoting arrangement provide possible pivoting operation of the furniture part. This can be a targeted or desired

Motion control done, especially to bring the furniture part in the first phase of movement safely in the disengaged position. The spring force supports an initiating force by an operator, for example, if this the furniture part from the closed state by pulling in Moved opening direction.

If appropriate, the spring means can also support a movement of the furniture part relative to the movement element in the direction of the front side of the furniture body or alone

cause.

The spring means form in particular an energy storage, which after its unloading, which is for example when

Disengaging the furniture part in the first movement phase

takes place, is loadable, for example, by an external influence on the furniture part by the operator in a manual movement of the furniture part.

It is also advantageous for the movement element to be displaceable on the receptacle via a linear guide which comprises a rail and bearing means acting thereon. The

Movement element can thus be moved in particular jerk-free on the bearing means on the recording.

In particular, it is advantageous for the linear guide to comprise a fixed rail on the receptacle and rolling elements running on the movement element. The rail is advantageous in the recording with a train or with opposing tracks available on which storage means such. B. rolling elements, which are accommodated on the moving element, run off or

can roll off. Basically, a reverse is also true

Arrangement possible.

The rail is present at the receptacle in particular vertically or vertically or horizontally aligned.

It is also advantageous that a guideway is formed on the receptacle, which is tuned to the pivot assembly such that the horizontal distance of

Furniture part to the front of the furniture body over the

Guideway dependent on the displacement position of the

Movement element along the recording can be influenced.

Thus, at different displacement positions of the each desired release distance of the furniture part are set to the front of the furniture body. In this case, the furniture part can also be aligned obliquely with respect to a flat vertical front.

For example, starting from a release distance at the end of the first movement phase or at the beginning of the

Displacement movement of the movement element of the release distance depending on the respective displacement position of

Movement element to be influenced.

According to a further advantageous modification of the invention, the receptacle comprises a housing, which in on a

Carcass wall inserted state forms an outer side region and an opposite inner side region of the respective body wall. This body wall material can be saved, since the housing otherwise replaced existing sections of a carcass wall. Instead of the attachment of the device to an inner side of the body wall, this is partially replaced in particular. In addition, space can thus be obtained within the furniture body, because otherwise a space in the furniture body occupied by the device, according to the thickness or the contour of the device by the patch on the inside of the body wall device.

The invention also relates to a piece of furniture with a

Furniture carcass and a furniture part which is movably received on the furniture body via guide means, with which the

Furniture part of a closed state relative to the furniture body, in which the furniture part occupies a maximum zoomed to a front side of the furniture body position, in a

Opening state of the furniture part can be brought relative to the furniture body and moved back into the closed state, with one of the above-thematized devices is provided.

In particular, the furniture part is designed as a front flap, wherein in the first movement phase of the opening operation, the front flap forward and possibly at the same time something can be displaced upward or laterally so that a lower or lateral region of the furniture body interior is released from the moving furniture part. This is already after a first operation, a part of the internal volume of

Furniture body freely accessible from an operating side. The

Furniture part does not need this a maximum advantage

cover possible opening path.
