Description

DESCRIPTION

Furniture with a coupling device

The invention relates to a piece of furniture with a coupling device according to the preamble of claim 1.

In the furniture construction sector, various coupling devices are known, with which two pieces of furniture that are movably mounted on a piece of furniture of a piece of furniture are temporarily coupled together. On the one hand it can be simplified as well! the design of a furniture front. On the other hand, for example, grip elements and closing means can be saved. In particular, it is known to cover a piece of mobile furniture by means of a front panel of another piece of mobile furniture, when the furniture is closed. In this regard, the piece of furniture, for example an external drawer, is equipped with a coupling element that can be attached, for example, to a contour on the surface of an internal drawer. However, this requires that a corresponding contour be available on the surface of the internal drawer. Such a piece of furniture, corresponding to the preamble of claim 1, is known for example from document DE 20 2005 020 203 U.

Over time, however, signs of deterioration may appear on the surface, for example of the internal drawer, which affect the appearance of the furniture and, if necessary, even the coupling function.

The objective of the present invention is to make available a piece of furniture with a coupling device for two pieces of mobile furniture, in particular for the temporary coupling of an internal drawer to an external drawer, which enables a compact construction mode and a reliable coupling and decoupling.

The objective is solved by a piece of furniture with the characteristics of claim 1.

Advantageous and preferred embodiments of the invention are set forth in the dependent claims.

The invention concerns a piece of furniture with a coupling device for two pieces of movable furniture, the pieces of furniture being mounted on a piece of furniture of a piece of furniture and a first piece of piece of furniture presenting a front panel that covers at least partially in a closed position of the first piece of furniture a front side on the front side of the second piece of furniture folded. The coupling device is equipped with two joining elements, which are intended for placement separately on both pieces of furniture. In this regard, at least one of the two joining elements is intended for placement on the front panel of the first furniture extralble and at least the other of the two joining elements is intended for placement on the front side in the front side of the second piece of furniture.

The core of the invention is that one of the two joining elements comprises at least two insertion projections, the insertion projections being arranged elastically in a predefined position with respect to one another, and in which the other of the joining elements It comprises a profile element in which at least one profile contour is configured, in such a way that the engagement projections grab behind the profile element in the profile contour for the transmission of traction forces in a coupled state and thus form at least one coupling match.

The profile element can have several profile contours. When the profile contours are arranged one after the other, for example along a direction of movement of the furniture removable, the furniture removable can be opened and closed together with different coupling distances. Moreover, for each of the insertion projections, an independent profile contour can be provided for its grip behind, whereby the corresponding engagement pairings can be arranged relatively freely with respect to each other. In addition, a profile contour can be continuously extended in the profile element in such a way that all the engagement projections can be attached together, for example at the same time. In this way, a defined engagement position can be ensured by means of multiple coupling engagement. Preferably, the profile element is configured in a first union element and the engagement projections in a second union element. In this way the functions of the joining elements are clearly separated from each other. It follows a relatively simpler structure of the coupling device and an easily understandable use.

By providing two or, if necessary, more engagement projections, which form with the profile contour of the profile element at least one engagement pairing, the likelihood that at least one of the engagement pairings provides for the transmission of tensile forces a coupling. In this way the joining elements can be joined for a coupling of the furniture pieces in a relatively faster manner, whereby the coupling device can be advantageously handled conveniently.

Preferably, at least one of the insertion projections is configured, and correspondingly stably connected with the joint element, such that with it it is possible to transmit only a predefined tensile force for coupled movements of the furniture pieces. If several of, in particular all, the insertion projections are like this! Robustly configured in one of the connecting elements, the coupling device is designed for advantageously redundant coupling. Thus, the coupling device has greater reliability.

The predefined positions of the insertion projections, in which these are elastically arranged relative to each other, are preferably adjusted to the profile element and, if necessary, also to the profile contour. In this regard, the positions of the insertion projections can be adjusted, for example, to be able to engage in the profile element and in particular in the profile contour at the same time, when the joining elements move towards each other for the coupling of The two pieces of furniture. By elastic arrangement it is meant in this case that the insertion projections are mounted in such a way that with an increasing deviation of the insertion projections from their predefined position with respect to each other similarly increasing recoil forces appear, which make the Highlights to fit their predefined position relative to each other.

For each of the insertion projections, an independent profile contour can be provided in each case in the profile element. The profile element can also have an individual continuous profile contour for a coupling of several or all of the insertion projections, in order to be able to release, for example, more easily, the coupling inserts of one another for decoupling the joining elements. The profile contour is preferably a edge, which defines a segment, in particular a surface, which essentially points in the direction of opening of the furniture pieces. In this way, forces with which an embossment can be engaged in a profile contour can be distributed over the surface, to reduce or avoid point loads and damages associated therewith.

A preferred embodiment of the invention provides that one of the two joining elements comprises at least two insertion projections, the insertion projections being arranged elastically in a predefined position with respect to each other, and that the other of the joining elements comprises a profile element in which at least one profile contour is configured such that the engagement projections grab behind the profile element in the profile contour for the transmission of traction forces in a coupled state and thus form! at least one coupling match, the coupling pairings being deactivatable. With the coupling pairs deactivated, the possibility of a coupling of the furniture pieces is prevented, for example, for example, the locking projections are provisionally locked in positions where a coupling in the profile element is not possible.

In this way, a user can adapt the invention to changing use situations, depending on whether or not a coupling of the furniture pieces is convenient, particularly during extraction. In addition, in a deactivated state, the insertion projections and the at least one profile contour in the profile element can be protected against unnecessary deterioration.

The two joining elements can be configured in such a way that the profile element is arranged in the coupled state between the engagement projections. The forces that keep each of the insertion projections attached to the profile element can be oriented in this respect in an opposite manner, whereby the insertion projections are supported against each other, as for example in pliers. When the insertion projections are engaged, the forces that appear can cancel each other out in such a way that such forces, in particular those that appear in the coupled state, do not cause additional stresses on the furniture pieces. The predefined position of the insertion projections can be predefined for example in such an embodiment by a diameter of the profile element in the profile contour. For a simpler coupling, the profile element is preferably narrowed at one end that is free, directed against the engagement projections. The joining element in which the insertion projections are configured can have one or more surfaces, or contours, that approximate each other as a funnel. In this way the profile element can be centered between the insertion highlights.

If the profile element is configured as a particularly open hollow body, the profile contour can be configured, for example, within the hollow body. Therefore, it is also conceivable that the profile element surrounds the engaging elements in a coupled state, when they engage within the hollow body in the profile contour. Accordingly, a predefined position of the engagement projections can be determined by an internal diameter of a hollow profile element.

To facilitate the insertion of the insertion projections, a funnel-centered centering structure in the profile element can be configured in this respect.

Preferably, one of the connection elements has an actuation element, which cooperates with the insertion projections so that a coupling connection of the connection elements can be released. From

This mode can achieve a relatively more reliable and more comfortable decoupling.

One of the connecting elements may have an actuating element, which cooperates with the engagement projections in such a way that it is possible to adjust a joint coupling of the joint elements in a stable manner. Ace! a more comfortable handling is achieved, when a frequent opening of the internal drawer is expected. When the elastic forces predefine a position of the insertion projections, in which they do not engage, a drive element may also be provided in the joint element for carrying, for example by actuation when removing one of the furniture pieces, the insertion projections to a hitch position. In such an embodiment, the ability to adjust a stable joint facilitates the use of the furniture pieces, when occasionally the second piece of internal furniture is used more frequently than a storage space of the first piece of furniture. piece of furniture.

The insertion projections may be configured in bearing arms that are configured in one of the connecting elements, projecting at least approximately in a direction of movement intended for coupling. In this way, a mobile assembly of the insertion projections in an elastically predefined position can be performed relatively easily. The insertion projections can also be removed, if necessary, by moving the supporting arms out of an embedded position.

Also, the profile element can be configured in an outstanding manner in a union element. In this way, the insertion projections can be housed protected in a joint element for example in a recess that is intended to receive the projecting profile element for couplings.

The supporting arms for the insertion projections can be movably mounted on one of the connecting elements, in particular pivoting or sliding. When the supporting arms are elastic, the supporting arms can be particularly rigidly fixed, for example, by one end to a segment of a connecting element. In this way, it can be dispensed with, in the case of mobile parts, for a mobile assembly of the insertion projections, so that the invention can be advantageously carried out robustly.

For the rest, it is preferable that at least one spring element is provided to press the engagement projections through the supporting arms in the direction of their position in each predefined case. This offers the advantage that relatively strong forces with which the engagement projections are maintained in a resting position can be predefined.

The profile element may be placed within a recess of one of the joining elements. In this way you can stay protected against fouling or damage.

The profile element may be floatingly mounted on the joint element, in order to reduce or even completely discard a transmission of forces, which may appear for example by guiding the furniture pieces during the opening and closing movements. In particular, it is preferable if the profile element is mounted on the joint element in such a way that a movement of an axis of the profile element at a solid angle is possible. In this regard, the profile element is preferably elastically maintained in a predefined middle position, from which it can be deflected in different directions. In this way the appearance of wear can be reduced both in the coupling device and in other parts of a piece of furniture, for example in glues. The profile element can be mounted, so that it can slide perpendicularly - for example horizontally or for example vertically - with respect to a direction of movement of the furniture pieces, in one of the joining elements.

The profile element can be configured as an elongated piece as a ribbon. In this respect, the profile contour can extend at least partially along its longitudinal axis. If a length of the profile contour exceeds a width of one of the insertion projections, through which it can be engaged in the profile contour, the insertion projection can slide, when engaged in the profile element, against the contour of profile along its longitudinal direction.

In this way, a degree of freedom for movements that advantageously reduces or completely prevents a transmission of guiding forces perpendicular to the direction of the opening and closing movements between the pieces is made available to the coupling device in the coupled state. of furniture. In particular, in combination with a profile element mounted in a floating manner, there is a possibility in this regard that the play during the coupled movements is distributed in different directions between a floating assembly of the profile element and a sliding engagement of the engagement projections. against an elongated shape of the profile element.

Otherwise, it is preferable that one of the insertion projections is configured at one end of a mobile mounted spike. This offers the advantage that a movement guide of an insertion projection, for example by means of a pin assembly, for example in a connecting element, in particular in a housing, is

controllable more precisely for a hitch.

Preferably, the drive element is configured to cooperate with the pins such that! All spikes can move at the same time. In this way, the coupling device can advantageously be decoupled reliably and comfortably.

Furthermore, a preferred embodiment of the invention is that the insertion projections are arranged around a recess of the bearing member, in which the insertion projections can be entered. The recess is provided in this regard to receive a profile element of a joint element that can be used as a complementary part. In this respect, surface segments of an inner side of the recess can absorb the forces that appear, for example, during a coupled movement, while the projections of the insert only guarantee the coupling of the two pieces of furniture.

Each of the insertion projections can be configured in an end segment that is free of a bearing arm. In this way, the insertion projections can surround, as the case may be, with the supporting arms, a profile element. The supporting arms could be configured, for example, in an elastically flexible manner, so as to arrange the elastic projections in a predefined position relative to each other.

15 Two or more of the supporting arms can be joined together by means of a Fork. By means of a fork, the insertion projections can be maintained relatively easily in a predefined position with respect to each other, the position of the insertion projections with respect to the joint element being variable. In particular, when the insertion projections are spatially distributed in such a manner, the insertion projections are engaged, when compressed from different directions, in a profile element located 20 in between, or the interlocking projections are engaged, when expanded in directions. different, in a surrounding profile element, the engagement projections can be coordinated with each other by means of a fork. In this way, the coupling device can be centered during the coupling of the joint element automatically on a symmetry axis, for example, common with the insertion projections and the profile element.

The fork can be configured so that it can move elastically for example as an articulation or for example as a deformable part.

It is also possible that the supporting arms are extended in particular on their respective longitudinal axis, beyond the fork to the operating levers.

The profile element can protrude free from one of the union elements, in order to enter, for example, a corresponding recess of the joint element that acts together.

30 Moreover, it is conceivable that each of the insertion projections is configured in each case at one end of an independent pin, mounted in a sliding manner. In this respect, the pins can be mounted, so that they can slide elastically, for example radially from or to a central point or a central axis, in for example a housing of one of the connecting elements.

In order to achieve a compact coupling that allows the assembly between two pieces of furniture, starting from the preamble of claim 1, a coupling device can be perfected so that in each of the joining elements magnetic means are arranged. The magnetic means can comprise for example a permanent magnetic element or for example a soft magnetic element or both types of magnetizable elements. In addition, an electromagnet can be included in the magnetic media. A coupling for the transmission of traction forces can thus be provided by magnetic forces, in particular of attraction. In this way, a device for coupling mechanically mobile parts can be dispensed with.

In combination with all the features of claim 1, the magnetic means may be provided, for example, to assist in the coupling of the engagement projections in the profile element, in order to center this with respect to a common joint axis. .

At least one of the two joining elements can present a permanent magnet.

Preferably, both joining elements are permanent magnets. An embodiment of this type may be independent of a power source.

At least one of the joining elements can be mounted an element of the magnetic means so that it can slide at right angles with respect to the direction of travel of the furniture removable. In this way, a coupling attraction can be reduced or completely canceled out, for example. Moreover, in this way the sliding magnetic element in one of the joining elements can follow, for example, the attractive magnetic means in the second joining element, when they appear during a coupled movement.

displacements of furniture pieces relative to each other perpendicular to the direction of movement of a common opening or closing.

Preferably, at least one of the joining elements can be adjusted so that, when the magnetic means approach, a coupling joint is impossible. In this regard, at least one magnetic element of the magnetic means in a first joint element can be adjustable in such a way that it is oriented with a repellent magnetic pole towards a magnetic element of the magnetic means of the second union element.

In one of the coupling parts, two permanent magnets can be fixed together in one of the other in predefined positions at a certain distance parallel to the direction of sliding of a magnetically mounted sliding element. The two permanent magnets in the predefined positions can be magnetized in opposite directions.

A piece of furniture with a coupling device, in particular in accordance with one or more of the above-described embodiments, has, thanks to the associated advantages, a resistant and reliable handling capacity of the attachable pieces of furniture and pieces of furniture as! United.

The invention is explained in more detail below in an example of realization and clarified with the help of drawings. In this regard, additional advantages of the invention are set forth.

An example of embodiment of a first piece of furniture according to the invention is shown in figure 1 with a coupling device 1, comprising two joining elements 2 and 3. The joining element 2 is shown in more detail in figure 2 .

The union element 2 is placed in a front panel 22 of an internal drawer 20. The union element 3 is inserted in a front panel 23 of an external drawer 21.

The union element 3 has a hollow essentially cylindrical base body 10, in which a profile element 9 in the form of a lath is inserted. In the connecting element 2, a clamp 4 is movably mounted, comprising two bar-shaped levers 5 and 6. On the front side of the front panel 22, the levers 5 and 6 protrude with a connecting arms 5a and 6a in the direction of the front panel 23 of the external drawer. In the internal drawer 20, the levers 5 and 6 are entered with actuating arms 5b and 6b. The elements of

union 2 and 3 are arranged in the respective front panels 22 and 23 in such a way with respect to each other that the

Insert arms 5a and 6a of the clamp 4 of the connecting element 2 can penetrate the hollow cylindrical base body 10 of the connecting element 3, when the front panels 22 and 23 move towards each other. In this regard, the connecting elements 2 and 3 are arranged in the front panels 22 and 23 such that the connecting arms 5a and 6a come into contact with opposite sides of the profile element 9 in the joining element 3 and can engage.

In order to transmit tensile forces between the connecting elements 2 and 3, the connecting arms 5a and 6a as! as the profile element 9 are adjusted together. For example, the insertion arm 5a has at its end that an insertion projection 7 is free that can clamp behind the profile element 9 in a profile contour 11; in the same way, the insertion arm 6a is configured with an insertion protrusion 8 to grasp a second profile contour 12 of the profile element 9 behind. By means of the grip behind the profile element 9 with the insertion protrusions 7 and 8 it is possible to transmit through the connecting arms 5a and 6a tensile forces to the union element from the union element 3 to the union element 2.

Figure 2 shows how the levers 5 and 6 of the clamp 4 are mounted on the connecting element 2. In the connecting element 2 a rectangular reception chamber is configured, in whose center a cylindrical rod 14 is raised. In the area of the rod the elongated walls 13a to 13d of the reception chamber 13 are interrupted by two openings 13e and 13f opposite each other. The lever 6 protrudes with the insertion arm 6a through the opening 13f and with a drive arm 6b through the opening 13e outside the receiving chamber 13. The insertion arm 6a and the actuating arm 6b are connected to each other by means of a annular segment 6c, the lever 6 being inserted with the annular segment 6c on the rod 14 and resting thereon so that it can rotate.

On the lever 6, at least one spring arm 6d is configured, which is supported on the wall 13c of the receiving chamber 13. In this respect, the spring arm 6d provides elastic forces, with which the lever 6 is pivoted. around the rod 14 to a position in which the lever 6 bumps into the opening 13e with the wall 13c. The lever 5 protrudes with the locking arm 5a as! as the actuation arm 5b also from the openings 13e and 13f, the insertion arm 5a and the actuation arm 5b being joined together by an arc 5c. The arc 5c is shaped in such a way that the domed surface of the annular segment 6c of the lever 6 is mounted and can slide in the pivoting movement along it. In the lever 5 a spring arm 5d is also configured, which is supported on a wall 13b of the receiving chamber 13. In this way, the lever 5 is also pivoted to a rest position, in which by means of the support of the lever 5 in the opening 13e in a wall 13b by the elastic forces of the spring arms 5d and 6d as! as the stop of the levers 5 and 6 in the opening 13e on the walls 13b and 13c, the insertion projections 7 and 8 in the insertion arms 5a and 6a are kept at a certain distance from each other, to which they still an insertion of the insertion projections 7 and 8 is possible in the profile element 9 also when the profile element 9 is not inserted exactly through the center between both insertion projections 7 and 8. The mobile assembly of the levers 5 and 6 in the rod 14 ace! As the elastic forces exerted with the spring arms 5d and 6d on the levers 5 and 6, it is also possible that a coupling of the front panels is possible with a predefined displacement perpendicular to the direction of movement of the internal drawer and the external drawer . Preferably, the profile contours 11 and 12 in the profile element 9 are configured for their entire length within the base body 10, in particular for its entire internal diameter. In this way, with a perpendicular position of the profile element 9, a coupling is also possible when the connecting elements 2 and 3 are displaced in their position in height relative to each other. Through the movable assembly of the clamp 4 in the connecting element 2 and the variable engagement possibilities in the profile element 9 it is possible, during the coupled movements of the internal drawer 20 and the external drawer 21, to limit the forces exerted about the profile element 9 as! as on clamp 4 in particular perpendicular to the direction of traction. This offers the advantage of lower wear occurrences in the coupling device in particular in the forms of the insertion projections 7 and 8 and the contours of profile 11 and 12.

Another example of making a piece of furniture according to the invention with a coupling device 1 is shown in Figures 3 and 4. The coupling device 1 comprises two joining elements 2 and 3, the joining element 3 coinciding placed in a front panel with that of the previously described embodiment. The joining element 2 has a rectangular, u-shaped mounting element, with which the joining element 2 can be inserted into a narrow side 22a of a front panel 22 of an internal drawer 20. In the joining element 2 is configured a rod 14, in which a clip 4 is mounted around a perpendicular axis. The clamp 4 has two levers 5 and 6, between which the rod 14 is centrally arranged. The two levers 5 and 6 of the clamp 4 are elastically joined together in such a way that they can pivot in particular in a common plane with respect to other. On the lever 5, an insertion arm 5a protrudes from the rod 14, at which end an insertion projection 7 is configured. On the lever 6 an insertion arm 6a with an insertion relief 8 is configured analogously, with the projections being configured. insert 7 and 8 prominently in each case in the direction of the opposite lever 5 or 6. The insertion projections 7 and 8 are in the form of a cradle, whereby the insertion arms 5a and 6a are narrowed in each case at their free end as asymmetric tips. In this respect, surfaces oriented towards each other are arranged as a funnel in the insertion projections 7 and 8, so that the clamp 4 can be automatically centered in case of contact with the profile element 9.

As shown in Figure 4, the clamp 4 can be rotated in the rod 14 180 °, whereby, instead of the connecting arms 5a and 6a, when the joining element 2 and the joining element 3 are only approached they introduce the drive arms 5b and 6b into the joint element 3. When the insertion arms 5a and 6a are in a position in which the insertion projections 7 and 8 can no longer be engaged in the profile element 9, the device of coupling 1 can be deactivated.

Figures 5 and 7 show connecting elements 2 and 3 of a third piece of furniture according to the invention with a coupling device 1, which is made as an embodiment. The connecting element 2 has a housing 16, in which the connecting arms 5a and 6a can be pivotally mounted separately. At the respective end of an insertion arm 5a or 6a, insertion projections 7 or 8 are configured, with which the connection element 2 can grasp behind a profile element 9 of the connection element 3. The connection arms 5a and 6a can pivot away from each other against elastic forces, whereby a grip position can be achieved behind in the connecting element 3. An actuation button 17 is provided to, when pressed, pivot the engaging arms 5a and 6a equally moving them away from each other, in order to release the insertion projections 7 and 8 of a coupling hitch. On a semi-circular cylindrical outer surface of the housing 16 a marginal shoulder 16b is configured. With the marginal shoulder 16b, the housing side 16a can be inserted into a corresponding adapter 18. The adapter 18 is provided to place the housing 16 of the connecting element 2 in a removable manner, for example in a front panel 22 of an internal drawer 20. According to Figure 6, it is cut for this on the front panel 22, in the area of a narrow side 22a, a rectangular recess for example semicircular or for example rectangular, into which the adapter 18 is inserted. For example, the adapter 18 may be attached or nailed to a recess of this type.

In a marginal area 18b, which covers the semicircular recess in the front panel 22, a socket segment 18a protrudes. The socket segment 18a is intended to engage on the housing side 16a within the marginal shoulder 16b. By engaging the socket segment 18a on the marginal shoulder 16b, traction and compression forces can be transmitted from the housing 16 to the front panel 22, when the housing 16 is inserted on the adapter 18. The socket segment 18a and the housing side 16a with the marginal shoulder 16b together form an insertion joint device, with which the coupling device 1 can be deactivated at any time by removing the connection element 2. If the connection element 2 is removed, with the adapter 18 in the recess of the front panel 22 a sunken handle is provided. Preferably, adapter 18 is configured such that the sunken handle can be used safely and pleasantly. For this, they can be rounded in the adapter 18, for example, ridges and, for example, the surfaces of a structured which reduces a slip when pulled.

By inserting the housing 16 into the front panel 22 with an engaging arms 5a and 6a that engage inwardly, an engagement of the engagement projections 7 and 8 in the profile element 9 is prevented and the coupling device is therefore disabled. By means of this type of deactivation of the coupling device 1, the union element 2 can be advantageously stored in its place of use, in order to prevent the union element from being lost or lost. Likewise, the housing 16 can be inserted on the adapter 18 in such a way that the connecting arms 5a and 6a are oriented in the direction of the connecting element 3 - in figure 3 -, whereby a coupling hitch of the projections of the projections is possible. insert 7 and 8 into the profile element 9 and the coupling device is like this! activated.

The connecting element 3 has a cylindrical base body 10, a profile element 9 being arranged in a central recess 10b. In the embodiment shown, the profile element is no longer firmly connected to the base body 10, but slidably mounted both perpendicular to the cylinder axis of the base body 10 and perpendicular to the longitudinal direction of the profile element. For this, the profile element 9 is connected at a top and bottom T-shaped end with plates. The plates are arranged in parallel with respect to each other and additionally joined together by an arcuate segment 25c, whose arcuate shape is adapted to the outer cylindrical envelope surface of the base body 10. Between the profile elements 9 and the arcuate segment 25c is It also has an intermediate space, which allows a probing arm with an insertion projection to reach a position of engagement in the profile element. In the base body, an upper and a lower guide chamber 10c and 10d are configured in which the sliding plates 25a and 25b are slidably mounted. The guiding chambers 10c and 10d reach the outer enveloping surface of the cylindrical base body 10, whereby the insertion element 25 can be introduced through the guiding chambers 10c, 10d in the connecting element 3. In addition, the chambers of guided 10c and 10d offer an additional possibility of deactivating the coupling device 1, if the profile element 9 is pushed with the insertion element 25 laterally out of a central position, located between the engaging arms 5a and 6a.

In Figures 8 and 9 another example of embodiment of a coupling device 1 with two joining elements 2 and 3 is shown.

The connecting element 2 has a flat parallelepipedic housing 16, in which an opening 26 is configured for the reception of a profile element 9 of the other connecting element 3. Around the opening 26, three insertion projections 7, 8 are arranged. and 27, which are shaped in each case as ends in the form of

cradle in spikes 28 parallelepipedics. The insertion projections 7, 8 and 27 are mounted with their pins 28 slidably in the housing 16 of the connecting element 2, these elastically and flexibly entering the opening 26. The pins 28 are mechanically coupled to an element of drive 17, with which the engagement projections 7, 8, 27 can return from a hook in the particular profile element 9 at the same time, in order to release the connecting elements 2 and 3 from each other. The insertion projections 7, 8, 27 can be removed, for example, by turning the actuating element 17 preferably completely out of the opening 26, in order to advantageously allow them to be released quickly and avoid damage to the insertion projections 7, 8 , 27 and in the profile element. For an embodiment not shown, it is also conceivable that, for example, a push button is provided as a drive element, with which the insertion projections 7, 8, 27 of the opening 26 can be extracted when the push button is pressed.

The connecting element 3 has a hollow cylindrical base body 10, which is intended for placement in an appropriate recess in for example a front panel of for example an external drawer.

On a front side of the base body 10, a stop ring 10a radially protrudes, which is intended to limit a recessed placement. Adjacent to the stop ring 10a there is radially inside an annular panel 10e with a circular opening 10f, concentric to the base body, through which the profile element 9 protrudes in the form of a cylindrical rod. On a wrapping surface of the cylindrical profile element 9, several other contours of profile 11, 12 are arranged along a cylindrical axis of the profile element 9, which surround the profile element as a circular ring-shaped groove. The contours of profile 11, 12 are shaped in such a way that they can be clamped behind by the insertion projections 7, 8, 27.

Preferably, the profile contours have a cross section for example in the form of saw teeth, whose flank that falls on a slope is directed towards the base body 10. In this way, the insertion projections 7, 8, 27 can advantageously slide protected against appropriate ramp surfaces (not shown) in mating positions.

The profile element 9 is connected for example in one piece with a circular disk 9a. The disk 9a has a diameter larger than the opening 10f. On one side of the disc 9 opposite to the profile element 9a, segments 9b are formed that protrude as a spring. The segments 9b are provided to rest on a support element (not shown) inside the base body 10, in order to press the disc 9a against the panel 10e. The diameter of the circular disk 9a is preferably smaller than an internal diameter of the essentially cylindrical hollow space of the base body 10, so that by a difference these two diameters can be predefined for example a radial clearance of the disk 9a and therefore also of the element of profile 9. As! a floating assembly of the profile element 9 can be achieved, by which the coupling device 1 of forces and stresses can be discharged during the coupled opening and closing.

Accordingly, a diameter of the opening 26 in the housing 16 of the joint element 2 can be adapted to the rod-shaped profile element 9 such that the profile element 9, in the case of an embedded position, can move relatively little in the opening 26. So that, in the case of different positions of the connecting elements 2 and 3 relative to each other, the profile element 9 can still be introduced! in the opening 26, the opening 26 is surrounded by one or several surfaces 16c that approach each other in the form of a funnel, which are provided as an introductory funnel for the profile element 9. In this way a coupling and decoupling of the coupling device reliably.

Two coupling elements 2 and 3 belong to the coupling device 1, which are provided for separate placement in, for example, front panels 22, 23 of furniture pieces - in this case an external drawer 21 and an internal drawer 20. The elements of connection 2, 3 are arranged in this respect on the front panels 22, 23 aligned one after the other forming a joint axis, which preferably runs parallel to the directions of the opening and closing movements of the furniture pieces 20 , 21. In this way, a coupling joint can be retained, if necessary, to a maximum outward opening position, for example, of the outer drawer 21. Two magnets 32 and 33 of hard magnetic material are housed in the joint element 3. The magnets 32, 33 are arranged side by side in a manner centered on a cylindrical base body 10. In this regard, the magnets 32 and 33 in the joint element 3 are oriented with antagonistic magnetic poles towards a circular outer front surface 10g (figure 11), which is directed towards the front panel 22 of the inner drawer 20. When interacting with a In this way, a relatively high retention force can thus be achieved, with a relatively high retention force, the magnetic flux being very concentrated.

The connecting element 2 of the coupling device 1 is placed with a housing 16 on the front panel 22 of the internal drawer 20. In the housing 16 a support 34 is mounted in a sliding manner, which can slide laterally with the aid of an element of actuation 17 in a horizontal direction, for example, at right angles with respect to an opening direction of the internal drawer 20.

Two additional magnets 30 and 31 of hard magnetic material are housed in the support 34 of the union element 2, which are available as complementary magnetized parts with respect to the magnets 32 and 33 of the element

of union 3 for a coupling. Therefore the magnets 30 and 31 are arranged next to each other with opposite poles in each other in the support 34, so that both can meet opposite poles that are attracted in the magnets 32 and 33, in order to generate a joint by traction between the connecting elements 2 and 3. In the coupled state the magnets 30 and 32 are attracted in each case in pairs as well as the magnets 31 and 33 with respect to each other. If the magnets 30 and 32 as well as 31 and 33 are in particular contact directly with each other, a strong magnetic attraction can make it difficult to separate the inner drawer 20 from the outer drawer 21 along for example a direction of closing the pieces of furniture. By means of the lateral sliding of the support 34 in the connecting element 2, a separation almost perpendicular to the direction of the magnetic attraction forces is possible. Additionally, by means of a sliding of the support 34, for example, the magnet 30 can be arranged with a repellent pole on the magnet 33, whereby an aid is available in an advantageously comfortable way to separate the furniture pieces 20 and 21.
