Description

The invention relates to a piece of furniture with a device for the detachable coupling of an outer drawer to an inner drawer. An inner space of a drawer unit may be additionally divided by an inner drawer, hereinafter called inner drawer. In this case, usually a front side of the inner drawer, in particular the front panel of a front panel of a surrounding drawer, hereinafter called outer drawer, covered. A front side of the drawer unit can thereby have a relatively closed front side. To move the inner drawer a variety of devices for releasably coupling an outdoor drawer with an inner drawer in various designs are known in the field of furniture.

The invention has for its object to provide a piece of furniture with a device for releasably coupling an external drawer with an inner drawer, which is relatively easy to manufacture and assemble.

The object is achieved by a piece of furniture with a device having the features of claim 1.

Preferred and advantageous embodiments of the invention are mentioned in the dependent claims.

The invention is based on a piece of furniture with a device for the detachable coupling of an outer drawer to an inner drawer, the outer drawer and the inner drawer being movably mounted in a piece of furniture. The device comprises a pivotally mounted driving lever with a hook element for hooking on the inner drawer.

The essence of the invention is that the driving lever is pivotally mounted with a pivot about an axis of rotation, which is arranged in the assembled state parallel to a main plane of the front panel of the outer drawer, and that an activation lever is provided, with the driving lever with the hook element in a hooked position on the front panel of the inner drawer can be brought into a driving position when the front panel of the inner drawer meets the activation lever. In addition to the driving lever is with the activation lever advantageous another means for controlling a coupling operation of the outer load on the inner drawer available. In this case, it can be ensured with the activation lever nesting of outer drawer and inner drawer, if, for example, when approaching the front panels of the inner drawer and the outer drawer a predetermined distance between the front panels is below. In this case, the activation lever, in particular by reducing the size of a gap between the front panels be movable so that the hook member on the inner tray is engageable by a movement coupling between the activation lever and the driving lever. An entrainment of the inner drawer can be achieved regardless of a weight and shape of the driving lever and the hook element. Furthermore, entrainment is also particularly independent of an additionally applied to the driving lever, for example, elastically yielding force, so that the driving lever can hold out in a decoupled arrangement with an example elastic force from a gap between the front panels. Furthermore, with the aid of the activation lever, it is advantageously possible to simply provide an additional force for an at least partially automatic coupling process, the Force direction of movement directions of the outside and the inner drawer is independent. The force direction is preferably adapted to the coupling process, for example, a pivoting movement of the driving lever. A pivoting movement of the driving lever can be provided in a coupling process, for example, to bring the hook element in a the front panel of the inner load engaging behind entrainment position.

The activation lever is preferably long, in particular designed to be longer than the driving lever. Thereby, upon impact and at e.g. sliding contact of the activation lever on the front panel of the inner drawer advantageous relatively small forces to be effective when the front panels of inner drawer and outer drawer approach each other. Preferably, the activation lever is provided with a smooth contact surface for contact with the front panel of the inner drawer. The contact surface may be e.g. be shaped, in particular curved, that the activation lever touches the front panel of the inner drawer with an at least approximately flat surface area. This can protect an outer surface of the front panel of the inner drawer and protect it from damage.

At one end point of a coupling movement of the activation lever can be arranged between the front panels of the outer drawer and the inner drawer, characterized in that a direct contact of the two front panels is advantageously avoided. Furthermore, can be provided by the device according to the invention advantageously an automatic coupling of the inner drawer to the outer drawer.

The activation lever can be attached, for example, with one end preferably on an inner side of the front panel movable, in particular pivotally mounted. In this case, the activation lever is preferably movable into a projecting from the inside and in particular in the direction of a front panel of the inner drawer projecting position. For activation, the activation lever may be pivotable, for example, from the protruding position into a position in which the activation lever, for example, on an inwardly facing surface of the front panel of the outer tray rests. A range of movement of the activation lever is preferably matched to the driving lever and in particular to the hook element such that a decoupling of the device from the inner drawer, for example an upper edge of the front panel of the inner drawer is ensured by a movement of the activation lever in the above position. An approximation of the front panels of the outer drawer and the inner drawer, for example, be limited by the fact that the activation lever is arranged in an activated end position, for example on both front panels in particular parallel adjacent.

In this case, a movement coupling between the activation lever and the driving lever is provided, through which a driving position of the driving lever and the hook element can be reached in the activated end position of the activation lever. The furniture according to the invention has a comparatively simple structure, which can be composed of few parts. In this case, the invention can advantageously be carried out in such a way that a special adaptation or processing of the front panel of the inner drawer for a coupling hooking the hook element is avoidable.

For a movement coupling of the driving lever with the activation lever, e.g. a transmission - for example with levers or e.g. toothed elements - be provided. In addition, the activation lever and the driving lever can be directly connected or in contact.

For a comparatively simple embodiment of the invention, the driving lever and the activation lever are preferably fixedly connected to each other, wherein the driving lever and the activation lever can be formed in particular as a single body of a continuous contiguous material. A longitudinal axis of the driving lever and a longitudinal axis of the activation lever are preferably to each other angled, in particular arranged at a right angle. The activation lever may be movable together with the drive lever, in particular pivotally mounted preferably on the pivot bearing. The axis of rotation of the pivot bearing can be arranged at right angles to the two longitudinal axes.

The driving lever and in particular the hook element can be provided and designed for hooking or engaging behind the front panel of the inner drawer. When hooking on the front panel, a coupled state of the inner drawer on the outer drawer for a user can be seen relatively quickly when the pivotally mounted driving lever and in particular the hook element are provided for hooking on an upper side, in particular on an upper edge of the front panel of the inner drawer.

A preferred embodiment of the invention may comprise an actuating element which is designed for a displaceable attachment to the front panel of the outer drawer, wherein the driving lever is rotatably mounted on the actuating element. In this case, the pivot bearing of the driving lever can be formed on the actuating element. By moving the actuator, for example, changed positions of the outer drawer and the inner drawer can be compensated for each other, wherein a change in position, for example, a change in the loading of the outer drawer or the inner drawer can be caused. Furthermore, a displaceable actuating element allows the hook element to be detached from the inner drawer and, in particular, from its front panel without pivoting movement of the entrainment lever. If, for example, the driving lever is hooked to the hook element on, for example, a narrow side of the front panel of the inner drawer, the entrainment coupling can be released by pushing the actuating element away from the front panel of the inner drawer, in particular from the narrow side. Together with the displaceable actuating element while the pivot bearing of the driving lever is removable from the inner drawer. An entanglement of the driving lever on the inner drawer can be avoided, for example, by the movement coupling with the activation lever.

In order to avoid entanglement of the driving lever on the inner drawer, moreover, mutually associated, mutually movable stop sections may be present on the pivot bearing, with which a pivoting movement for hooking the driving lever is limited. A first stop section of a corresponding stop pair may be fixedly connected to the actuating element, while a second stop section of the stop pair may be fixed in place, e.g. can be arranged on the driving lever.

Preferably, a displacement spring is provided on the actuating element, which can move away the actuating element from a decoupling position, wherein the hook element of the driving lever is removed from a engaging engagement on the inner drawer. As a result, as a rule, e.g. be favored by a user a coupled state of the outer drawer to the inner drawer without special measures.

For a preferred embodiment of the invention spring means may be provided with which the driving lever in a standby position for hooking the front panel of the inner drawer is durable. In a mounted state of the device, the driving lever in the standby position, e.g. pointing obliquely upward from an inner side of the front panel of the outer tray, e.g. pointing in the direction of the furniture body. The activation lever is then provided to overcome the lifting action of the spring means and to lower the driving lever for engagement of the hook member. In this case, the activation lever can be, for example, also by the spring means in a position on the front panel of the outer drawer projecting inward position. A part of the spring means may be anchored to the actuating element, wherein a second anchorage for the spring means may be provided on the driving lever and / or on the activation lever.

The spring means may be adapted to frictional forces of a guide of the inner drawer, that in a coupled position, the spring forces of the spring means not to sufficient to overcome frictional forces to move the inner drawer away from the outer drawer. As a result, decoupling of the device remains substantially under the control of the user.

Preferably, the driving lever and the activation lever are held in a standby position on the actuating element such that, during a hooking operation, the driving lever is displaced upward with the activation lever on the actuating element. As a result, an automatic coupling through the device is also achievable when the inner drawer has taken a different altitude depending on the load condition.

The driving lever can engage in a driving position via latching means. By means of the latching means it can additionally be avoided that the driving lever and in particular the hook element detach themselves from a coupling position automatically. The latching means are, for example, such that the detent is released in the driving position by displacing the driving lever with the actuating element upwards. Thus, the driving lever can pivot with the activation lever in a hitting the front panel of the inner slide upwards and moves into the ready position. By the latching means, unintentional release of the driving lever by a pivoting movement in e.g. the standby position is difficult or blocked.

a schematic frontal view of the inner sides of front panels of an inner drawer and an outer drawer in the coupled state.

In the FIGS. 1 to 3 an exemplary example of a furniture 1 according to the invention with a coupling device 6 is shown on the furniture 1, with which an inner drawer 3 can be coupled to an outer drawer 2 for entrainment especially when pulling out the outer drawer. From the furniture 1 are in FIG. 1 only the inner drawer 3 and partially a front panel 2a of the outer drawer 2 shown.

On an area portion 2b of the inside of the front panel 2a, an actuating element 7 of the coupling device 6 is slidably mounted. The actuator 7 is mounted vertically displaceable on the inside of the front panel 2a.

At a lower end portion of the actuating element 7, a pivot bearing 11 is formed, on which a driving lever 8 is pivotally connected to the actuating element 7. The driving lever 8 is mounted about a horizontal axis of rotation up and down pivotally mounted on the pivot bearing 11. In Fig.1 the take-off lever 8 is shown in an upwardly pivoted standby position, wherein the same driving lever is represented by the reference numeral 8 'in a position coupling the inner load 3 to the outer load 2.

At a free-standing end portion of the driving lever 8, a hook member 9. In the coupling position of the driving lever 8 ', the same hook element 9' is provided to engage behind a front panel 4 of the inner tray 3. By concerns on an inner surface portion 4c of the front panel 4, the hook member 9 'in the coupling position, the inner tray 3 move along when the outer tray 2 is pulled out of the furniture 1.

A coupled state is from a perspective looking at the furniture 1 from inside to outside FIG. 3 shown.

In the region of the rotary bearing 11, the driving lever 8 is in particular fixedly connected to an activation lever 10, wherein the activation lever 10 and the driving lever 8 are preferably formed as a one-piece component. By the connection of the activation lever 10 with the driving lever 8 an immediate movement coupling of the two levers 8 and 10 is provided. When the driving lever 8 is in the standby position, the activating lever 10 is disposed with a free-standing end portion protruding from the inward facing area 2b of the front panel 2a of the outside tray 2. In a coupled state of the inner drawer 3 with the outer drawer 2, the front panel 4 of the inner drawer and the front panel 2a of the outer drawer 2 are approximated to one another such that the same activation lever 10 'rests in parallel on both front panels 2 and 4.

In Fig.2 is a part of the Fig.1 shown with further details. The actuator 7 is pressed by means of a spring 13 down and can be to release a coupling of the inner tray 3 to the outer drawer 2 pull against the force of the spring 13 upwards, at the same time the driving lever 8 and the activation lever 10 are moved upward.

On the activation lever 10 engages as a spring means, for example, a compression spring 12 which holds the activation lever 10 yielding in a protruding from the inner surface portion 2b position. Due to the connection of the activation lever 10 with the driving lever 8 thereby the driving lever 8 is held in the standby position for coupling the inner tray 3. In the course of coupling the inner drawer 3, the front panel 4 approaches the front panel 2a, thereby pivoting the activation lever 10 down into a position parallel between two front panels 2a and 4. Due to the movement coupling with the activation lever 10 of the driving lever 8 is moved down and the hook member 9 behind the front panel 4 of the inner tray 3.

In Fig.2 are an upper altitude B and lower altitude C a top 4b of the front panel 4 of the inner tray 3 with respect to a position A of the pivot bearing 11 shown. Here, the altitude B may correspond to a less heavily loaded state of the inner tray 3 than the altitude C. The actuating element 7 is located in a downwardly pressed position on the front panel 2a of the outer drawer 2, which is required in particular for the ready position of the driving lever 8. The coupling device 6 is mounted on the front panel 2 a such that a coupling of the inner tray 3 at both altitudes B and C is possible. When the inner tray 3 is in the high position C, only the activation lever 10 and the outer surface area 4 a of the front panel 4 of the inner tray 3 are in contact with a coupling. When the inner tray 3 is in the high position B, the front panel 4 may be simultaneously in contact with the driving lever 8 and the activation lever 10. Preferably, the activation lever 10 is formed so long in particular in the longitudinal direction that with the contact point of the activation lever 10, a greater lever moment is achievable, as with a contact point of the driving lever 8, which is struck by an upper edge 4d of the front panel. As a result, the driving lever 8 can be supported on the upper edge 4d. When the front panels 2 and 4 are brought closer to one another, a lever moment can be transmitted from the activation lever 10 to the driving lever 8, with which the driving lever 8-supported on the upper edge 4d-can slide the pivot bearing 11 and thus also the actuating element 7 vertically upwards. Accordingly, the coupling device 6 offers the advantage that the coupling device 6 makes it possible to couple the inner load 3 to the outer load 2 in, for example, different loading states of the inner load 3 and outer load 2.
