According to the invention, the adjustment unit (2) comprises a stop part that can be resiliently deflected from a starting position, wherein the stop position is determined by the extent of a deflection in a fixed deflection position of the stop part.

Description

"Furniture and device for a furniture"

State of the art

In furniture with a movably received on a body furniture part devices with an adjustment for fixing a closed position of the furniture part are known. With the adjustment, it is possible to specify an executable during normal operation of the furniture closing movement of the furniture part in its end by providing an end point defining adjustable stop. This is especially true for furniture with furniture parts such as e.g. Drawers necessary, which are completely retracted in the closed state in a receiving volume of the body. As a rule, a front side of the furniture part is not over at one end face of the body. Furniture parts with retractable front are included

Drawers also referred to as "inset drawer". In this case, a front panel can be reduced so that no edge areas on sidewalls or a bottom of the drawer survive. Thus, the missing projections of the edge regions at the front of the drawer can not be used as a mating surface for contact with a stop e.g. Serve with an end face of the body. This is the front of the furniture part or on the body no way to set an end point of the closing movement of the furniture part. An end point of the closing movement is therefore specified elsewhere.

CONFIRMATION COPY Depending on the manufacturing tolerances of components and / or

Deviations in the mounting accuracy e.g. one

Guiding device for the movable furniture part, it may also happen that the furniture part in the closed state or in stop position is not at a desired

Closing position is located or moved to other or adjacent furniture parts differently far in the body. This regularly leads to an inconsistent front image of the furniture.

Purpose and advantages of the invention

Object of the present invention is to be able to pretend improved in furniture of the aforementioned type, a closing situation.

This object is solved by the independent claims.

The dependent claims relate to advantageous

Further developments of the invention.

The invention is initially based on a device for a piece of furniture, which is movably received on a body

Furniture part comprises, wherein the device is used to determine a stop position of the furniture part, with a

Adjustment unit which has an adjustable stop and which limits a normally-executable closing movement of the furniture part. An essential aspect of the invention is that the adjusting unit comprises a resiliently deflectable from a starting position stop member, wherein the stop position is determined by the degree of deflection in a fixed deflection position of the stop member.

According to the invention can advantageously in the state of

closed movably received furniture part a

Stop position for the furniture part are easily adjusted. The adjusting unit can in particular directly or also

be connected indirectly fixed position with the movable furniture part or with the body. The deflectable stop member can turn directly or indirectly on the corresponding other component of the furniture, so be supported either on the movable furniture part or on the body. The deflection of the abutment part for

Determining the stop position can be adjusted from the initial position basically in two opposite directions of deflection and fixed in a predetermined deflection position. The stop member can be adjusted from the initial position but also deflected in only one direction. In the first case, a maximum coverable adjustment can be greater, for example, be twice as large compared to the second case with otherwise comparable boundary conditions.

In particular, it is advantageous that the

Fixing device or the adjustment as a

Component is formed. This component may vary depending on

Application case optionally in different places

be provided.

The device is particularly advantageous for a piece of furniture, which has a front side with a furniture part front and a

Body front comprises and outer dimensions of the furniture part front are smaller than outer dimensions of a free cross-section of a front-side receiving opening in the body, to which a space for receiving the furniture part in the body connects. Thus, during the movement of the furniture part, the furniture part front is spaced over a comparatively small gap

Portions of the body bounding the receiving opening. This concerns e.g. Front-reduced drawers or "inset-drawers", which do not have a wide front panel, but only a front panel that is as wide or high as the given by side panels and bottom outside dimensions of

Drawer body. With the adjusting unit according to the invention can be advantageous a flush flush sinking the

Front of the furniture part to an end face of the body or to a flush with this or parallel to this level.

With the resiliently deflectable stop part, a stop position can be particularly simple and precise or

in particular continuously adjustable. The operation of the adjustment by a person is done eg with a simple tool or preferably without tools, in particular with a simple hand movement.

It is particularly preferred that the adjusting unit is provided on a coupling device for the particular latchable and detachable attachment of the furniture part to a movement rail associated with the furniture part. The coupling device may be formed, for example, as a detent coupling, which is attached to the underside of a furniture part floor and mounted in the

State snaps into a latching section on the motion rail. Because such attachments are available anyway and are particularly suitable for receiving the adjustment. Thus, with the attachment of the locking coupling without further effort, the assembly of the adjustment. In addition, the underside of the furniture part is the adjustment for the

Service generally accessible. When closed

Furniture part is then the stop part of the adjustment in operative connection with the body or a guide rail on the body.

Preferably, the degree of deflection of the stop member is predetermined by an acting on the stop member position variable actuator. Thus, e.g. even with cramped

Spaces are adjusted in the region of the stop member of this from a spaced location. For this purpose, only on the position variable actuator

be acted upon directly or indirectly, which can be done in different ways. The actuator can thus at least the essential distance between the Einwirkbzw. Bridge the control panel and the stopper part.

It is further proposed that the adjustment unit comprises a base body with the resiliently formed stop member and the control element guided on the base body. Thus, the adjustment can be made compact from a component.

Further, it is advantageous that one about an axis of rotation rotatably mounted control element is provided such that by rotation of the operating element, a displacement of the actuating element takes place. So can by a simple rotation adjustment

For example, by hand, the displacement of the actuating element and thus an exact fine adjustment of the deflection or the degree of deflection of the stop member can be achieved.

It is also advantageous that the control element and the control element are coordinated so that the

Rotary axis of the operating element extends transversely to a direction of displacement of the actuating element. So can also spatially

difficult boundary conditions a shift of the

Adjusting element take place in a direction in which itself can not be acted directly on the actuator.

Rather, the adjusting element can be moved by lateral action with a correspondingly greater distance.

In particular, it is advantageous that a

Wedge gear arrangement is provided, via which the

Rotary movement of the control element in an adjustment of the control element can be transferred. A wedge gear arrangement is particularly space-saving, simple and reliable.

Further, it is advantageous that the control element, a first threaded portion and the actuator a second

Thread portion is present, which are coordinated with each other, to effect a change in position of the actuating element in a rotary operation of the operating element. Thus, a rotational movement of the operating element by the action of a person can be made particularly sensitive, so that correspondingly very sensitive or infinitely one

Position change, for example, a displacement movement of the control element is achieved and thus a measure of

Deflection of the stop member can be made. The adjustment of the deflection of the stop member can

for example in the range of a fraction of a millimeter. It is also proposed that the operating element and the adjusting element are coordinated so that the

Rotary axis of the control element is aligned parallel to the displacement axis of the actuating element. Thus, the operation can be made spatially in extension of the longitudinal axis of the actuating element. In addition, the adjustment can be made very space-saving or simple in this way.

Another essential aspect of the invention is that the adjusting unit comprises a rotatable operating element, by which a slidably received

Stopper is adjustable to determine the stop position by the amount of displacement of the stop member and wherein the axis of rotation of the operating element in the direction of

Displacement of the stop member is oriented. With the

Displacement arrangement can be a particularly stable

Realize construction. In contrast to the deflectable stop member no joint is needed, whereby the adjustment is particularly simple and compact formable. Nevertheless, here is a very sensitive adjustment of the stop part and thus a fine adjustment with respect to the position of

closed furniture part possible.

Advantageously, a rotation is provided for the slidably received stop member. So can

be ensured that during the rotation of the

Control element it comes to no turning of the stop member when the two parts for an adjusting movement, for. via a threaded arrangement miteinender in meshing engagement. With the interaction over coordinated

Threaded portions on the control element and the stop member can also be realized a self-locking or locking arrangement. During operation possibly occurring vibrations and / or jerky forces when closing the furniture part can not lead to undesirable adjustment of the stop member.

Basically, in this regard, advantageously, another or separate arrangement for automatic backup a set position of the stop member be present.

It is also advantageous that a detachably mounted contact portion is provided on the stop member, which in a stop situation at a counter portion in a

Stop contact arrives. For example, one formed from a particular resistant material

Contact section are provided in particular interchangeable. Optionally, a damaged contact portion can be easily replaced.

The invention also relates to a piece of furniture with one of the devices discussed above.

This can be on a piece of furniture, for example, with a

Carcass on which several movable drawers with reduced front part dimensions or a plurality of inset-drawers are included, advantageous for each drawer with one each

associated adjusting a closing or

Carefully adjust the stop position in the closed position of the drawer in the body. As a result, can

accurate to the millimeter with a front of the furniture

aligned front surfaces of all drawers are set up, which is particularly advantageous from an optical point of view.

Figure 1 shows a detent clutch 1, not described in detail, with an existing thereon according to the invention console or adjusting 2. The detent 1 is attached, for example, to a bottom of a furniture drawer and is used for latching connection of the drawer with a

Drawer rail, which is used for the sliding guidance of the

Drawer on a carcass serves. The drawer rail is part of a known telescopic full or partial drawer with relatively movable guide rails, of which a cabinet rail is fixed in position fixed to the carcass.

The adjusting unit 2 may be, for example, releasably, but firmly fixed to the latching coupling 1 added.

The adjusting unit 2 is in particular made of plastic

made and includes a main body 3, with a thereto integrally formed deflectable stop member, which is designed as a stop tongue 4, which is provided in its foot with a bending joint.

In FIGS. 1 to 6, a neutral one is in each case

Closing position in the body is maximum retractable.

At the upper free end of the stop tongue 4 is a

cap-like or releasably plugged contact section 5 available. In addition, in the main body 3 are aligned at right angles to each other and penetrating

Receiving holes 6, 7 present, the central axes intersect. In the mounting hole 6 is a screw as

Received 8 trained control element 8, with a displaceable in the receiving bore 7 adjusting bolt

9 cooperates, which serves as an adjusting element of the adjusting unit 2.

The adjusting screw 8 has on its cylindrical outer casing 8 a on an external thread 10, not shown, which on a likewise not shown internal thread 11 in the

Receiving bore 6 is formed coordinated. Thus, by turning the adjusting screw 8, this zoom different depending on the direction of rotation in the receiving bore 6 or

be turned out. For this example, a

Twisting tool on a cross-shaped engagement contour 12 frontally outside of the adjusting screw 8 are recognized.

By turning the screw 8, this can in

Arrow direction PI (see Figure 4) are moved, so that by a sliding contact of a front on the screw 8 rotating chamfer 13 with a circumferential matching bevel 14 on the adjusting bolt 9, the adjusting bolt 9 in the direction of arrow P2 (Figure 4) is moved. The chamfers 13, 14 form effective force or motion transmission surfaces of a wedge gear arrangement 15 between the adjusting screw 8 and the adjusting bolt 9.

One of the stop tab 4 facing contact lug 16 front of the sliding in the receiving bore 7 adjusting pin 9 comes thereby in contact with a free upper end of the stop tongue 4 (see Figure 4). Thus, the hinged to a base portion 3a of the base body 3 is resilient

deflectable stop tongue 4 according to arrow P3 in Figure 4 bent forward bent. In this case, the contact portion 5 is moved in the direction P3 forward and thus a

Deflection position or a measure of the deflection of the stop tongue 4 and thus a change in position of the stop tongue 4 and the contact portion 5. With the set deflection is correspondingly a mechanical stop for a

Closing movement of the movably received furniture part fixed to a body.

The bending characteristic of the stop tongue 4 can be determined by the type, shape, e.g. the material thickness in the foot region of the stop tongue 4 and / or the choice of material of the bending regions are predetermined or coordinated.

The contact nose 16 is cylindrical and in diameter

Reduced relative to the diameter of the displaceable in the receiving bore 7 part of the adjusting pin 9. The adjusting pin 9 must overcome for bending the stop tongue 4 acting by bending the stop tongue 4 counterforce or spring force. This counterforce is permanently in the bent or deflected state of the stop tongue 4 on the adjusting bolt 9. Therefore, a self-locking is provided, which in case of non-actuation of the adjusting screw 8 a

Retreating of the adjusting pin 9 in the direction opposite to the arrow P2 prevented and over the meshing engagement

standing external thread 10 and internal thread 11 is realized.

With the adjusting unit 2 described can be a

Variety of different stop positions with the adjustment 2 fine-scale set. This can be a

Front of the movable furniture part in the closed state set to the millimeter.

The stop tongue 4 is limited in its Auslenkweg according to arrow P3, wherein a Auslenkweg from the shown

Starting position can be up to a maximum deflection of several millimeters to over one centimeter. Of the

Auslenkweg correlated according to PI with the adjustment of the

Adjusting screw 8 in the receiving bore 6 and P2 according to the displacement of the adjusting bolt 9 in the receiving bore. 7

For clipping the e.g. slightly elastic contact portion 5 at the top of the stop tongue 4, the stop tongue 4 is provided in accordance with cuts or paragraphs, which are matched to corresponding slightly compliant mounting jaws 17, 18 and 19 on the contact portion 5. Of the

Contact section 5 can also mechanically damping or

be designed to reduce noise, for example, consist of an elastomer or rubber material.
