The present invention relates to a cabinet insert with storage compartments, which can be used in a wall unit and can be swung from an upper, retracted into the upper cabinet position in an extended from the upper cabinet and down offset position, including the cabinet mounting part aligned parallel pivot lever which on the one hand hinged to the cabinet mounting part and on the other hand be hinged to an insertable and attachable in the wall unit supporting element on which support member, a first pivot lever and a second pivot lever are each pivotally mounted in a first pivot bearing, which are each pivotally connected via a second pivot bearing with a support member ,

Such cabinet installation parts are known, cf. DE-A-100 02 296 , In today's kitchen facilities, one endeavors to use the available space as optimally as possible. Therefore, also upper cabinets are used, which often extend to the ceiling, the accessibility in the upper area of these wall cabinets is not possible for a person who has a normal size, without climbing aid. These cabinet-mounted components allow it to be swung out from an upper retracted into the upper cabinet position in an extended from the upper cabinet and down offset position, whereby the accessibility is ensured on the held in this cabinet insert shelves in a comfortable working height.

These known cabinet installation parts with storage compartments are usually held by two pairs of pivot lever in the upper cabinet. Here, a respective pair of pivot levers is arranged on both sides of the cabinet installation part, for which purpose it is equipped with side walls. In order to ensure a parallel swinging down from the wall unit and pivoting into the wall unit of this cabinet installation part, these two side walls must be torsionally rigid connected to each other, which requires the use of rigid fasteners, which is expensive. It is also in the assembly of this cabinet installation part in Upper cabinet required that the bearings of the swivel lever pairs must be mounted on both sides of the upper cabinet, which also makes the installation complex.

The object of the present invention is now to provide a cabinet installation part with storage compartments, which has a simple structure, and which can be mounted with little effort in each wall unit.

According to the invention, the solution of this object is achieved in that the support member comprises a rod-shaped stand on which rod-shaped stator two parallel aligned first plates are mounted, between which two first plates of the first pivot lever and the second pivot lever are arranged, that the support member of two more Plates is formed, which are aligned parallel to each other and connected to each other, and between which two further plates of the first pivot lever and the second pivot lever are arranged, and that on the support member at least on one of the further plates on the outside of the storage compartments are attachable.

Due to the configuration of the invention with only one pair of pivot levers, the support element to which these pivot levers are hinged, be attached in any way on one or the other side or in a central region of this wall unit, which can be done by a simple installation, depending on the location This support element in the upper cabinet can then be attached to the support member on one side or on both sides storage compartments. This gives a variety of applications, the width of the wall unit can be fully exploited by the appropriate choice of the width of the storage compartments, the storage compartments bearing construction remains the same for each application.

Advantageously, the rod-shaped stator is provided on one side with a mounting plate, in which stand on the other side telescopically a profile is used, on whose aussenseitigem end also a mounting plate is arranged, and which profile with respect to the rod-shaped stand in each position can be fixed , Thus, the support element can be adapted to different heights of a wall unit, the attachment is very simple, by the arrangement of the mounting plates can be the support element at the bottom and at the top Fasten cover of the upper cabinet, the attachment of this support element is thus independent of the rear wall of the Upper cabinet, which is often formed from a non-stable cover or is even completely omitted.

Advantageously, the first pivot lever and the second pivot lever are formed from hollow profiles. By this configuration, one obtains a very stable mounting of the pivot lever on the support element, in addition, the first pivot lever and the second pivot lever are very torsionally rigid.

A further advantageous embodiment of the invention is that the mutual distance between the two further plates is so large that the two first plates come to lie between the two other plates. This embodiment of the support member also improves the stability.

Advantageously, on the outside of the two further plates Einhängeelemente be attached, in which the storage compartments can be mounted. As a result, various embodiments of storage compartments can be used as needed, for example, trays, trays, baskets, etc ..

Advantageously, a spring element is attached, which is hinged on the one hand in a pivot point on one of the two pivot lever and on the other hand held on the rod-shaped stand. As a result, the weight of the cabinet installation part with the storage compartments and utensils arranged thereon can be compensated so that an operator who wishes to extend the cabinet installation part from the upper cabinet or bring it into the retracted position does not have to expend too much force.

Advantageously, the articulation point of the spring element is arranged displaceably in the longitudinal direction of the pivot lever and are mounted for displacing and locking the articulation point displacement means. As a result, the acting spring force can be adapted to the weight of the cabinet installation part with the storage compartments and the utensils arranged thereon.

A further advantageous embodiment of the invention is that the one end of a damping element is hinged to the rod-shaped stand, whose other end is articulated on one of the two pivot levers. This avoids that too strong or too weak spring force, the cabinet insert part when it is released by the operator person, with too high speed hits the extended or retracted position.

Advantageously, an operator handle is attached to the support member, whereby the operation is simplified for a person.

A further advantageous embodiment of the invention is that the pivoting in and out of the cabinet installation part in and out of the upper cabinet is driven by a motor. For this purpose, for example, instead of the damping element, a linear drive may be provided which is electrically actuated by pressing a button.

An embodiment of the invention will be explained in more detail by way of example with reference to the accompanying drawings.

In the Fig. 1 to 3 is schematically illustrated a wall unit 1, as used for example in kitchens. This top cabinet consists in a known manner from a bottom 2, an upper cover 3, two side walls 4 and 5 and a rear wall 6. For reasons of clarity, the front cover is omitted, which may for example consist of two hinged doors.

In this upper cabinet a cabinet installation part 7 is used, which is equipped with storage compartments 8. These storage compartments 8 are made in the present embodiment of baskets, of course, other storage compartments, such as trays or trays are conceivable.

The cabinet installation part 7 comprises a support element 9, which is inserted and fixed in the upper cabinet 1. The support member 9 has a rod-shaped stand 10 which is fixed to the bottom 2 and to the upper cover 3 of the upper cabinet, as will be seen later in detail. At this stand 10 two parallel aligned first plates 11 are attached. Between these two first plates 11, a first pivot lever 12 and a second pivot lever 13 is arranged. This first pivot lever 12 and the second pivot lever 13 are each pivotally mounted in a first pivot bearing 14 between the two first plates 11 and 12.

Pivoted to the first pivot lever 12 and the second pivot lever 13 is in each case via a second pivot bearing 15, a support member 16, whereby a pivotal connection is obtained. This support member 16 is formed of two further plates 17, which are aligned parallel to each other and connected to each other via a web 18. Also in this support member 16, the first pivot lever 12 and the second pivot lever 13 between the two further plates 17 are arranged. These two further plates 17 have a mutual distance from each other, which is so large that the two first plates 11 of the support element 9 find space between these other plates 17.

On the outside of the two other plates 17 Einhängeelemente 20 are attached to which the storage compartments 8 can be hung at different heights on both sides.

The two first pivot bearings 14 and the two second pivot bearings 15, via which the first pivot lever 12 and the second pivot lever 13 are pivotably held on the support member 9 and the support member 16, form the vertices of a parallelogram. As a result, the support member 16 with the storage compartments 8 mounted thereon can be moved in parallel by a position extended from the upper cabinet 1 and offset downwards, as shown in FIG Fig. 1 is shown in a retracted into the upper cabinet 1 position, as in Fig. 3 is shown to be pivoted, with an intermediate position, as shown in Fig. 2 is shown, is passed through. Here, the first pivot lever 12 and the second pivot lever 13 are each formed of a square profile, whereby the bearings between the two first plates 11 and the two further plates 17 are formed very stable. By using the square profiles you also get an optimal torsional rigidity of the entire system. At the web 18, via which the further plates 17 are connected to each other, is an operator handle 19th attached, over which an operator person can bring the support member 16 in the respective desired position.

In the Fig. 1 to 3 an embodiment is shown in which the cabinet installation part 7 is arranged in a central region in the upper cabinet 1. As a result, storage compartments 8 can be hung on the support member 16 on both sides, which have the same length. Of course, it is also conceivable to install the cabinet mounting part 7, for example in the immediate vicinity of a side wall, on the support member 16 can then be mounted only on one side storage 8. The cabinet installation part 7 can also be fastened in a lateral area in the upper cabinet 1, so that narrow storage compartments can be hung on one side on the support part 16, while on the other side on the support part 16 wider storage compartments can be hung. One is very flexible here, by choosing the width of the storage compartments 8, the space in the upper cabinet 1 can be utilized in an optimal manner. The small width of the cabinet installation part 7 also contributes to this optimum utilization of space. In the case of the known cabinet installation parts of this kind, both sides are used with the corresponding pivoting levers, as a result of which the space required by these supports is practically twice as large as in the present inventive solution.

Like from the 4 to 6 it can be seen, the rod-shaped stator 10 of the support element 9 consists of a first hollow profile 21, which is designed as a square tube. On the lower side of this hollow section 21, a mounting plate is arranged, by means of which this hollow section 21 can be screwed in a known manner to the bottom 2 of the upper cabinet 1. From the other side, a further profile 23 is telescopically inserted into the hollow profile 21. This further profile 23 is also equipped on the outside with a mounting plate 24 which is fixed to the upper cover 3 of the upper cabinet 1 by screwing. Due to the possibility of moving the further profile 23 in the hollow profile 21, the rod-shaped stator 10 can thus be adapted to the respective height of the upper cabinet 1. In a known manner, then the further profile 23 can be fixed with respect to the hollow profile 21, for example by adjusting screws.

On the hollow profile 21 of the rod-shaped stator 10, the first plates 11 are fixed, the first pivot lever 12 and the second pivot lever 13 are pivotally mounted in these first plates 11 via a respective first pivot bearing 14. About the second pivot bearing 15 of the first pivot lever 12 and the second pivot lever 13 is hinged to the other plates 17 pivotally, which further plates 17 form the support member 16.

In Fig. 4 the support member 16 is shown in the extended and downwardly offset position from the upper cabinet. This position is reached when the first pivot lever 12 and the second pivot lever 13 are adjacent to each other, thereby a stop is formed for the lower position.

The first pivot lever 12 is provided with an extension 25 which projects beyond the first pivot bearing 14. In this extension 25 a pivot point 26 is attached, via which a spring element 27 is pivotally connected to the extension 25 of the first pivot lever 12. The other end of the spring element 27 is articulated on a tab 28 which is fixed to the hollow profile 21 of the rod-shaped stator 10. With this spring element 27, which acts as a compression spring, the weight of the support member 16 can be compensated with the storage compartments 8 and the utensils housed thereon. In order to set the force acting on the first pivoting lever 12, the articulation point 26 can be displaced in a longitudinal slot 29 mounted in the extension 25 via displacement means 30, as will be described later.

At one of the extension 25 attached to the projection 31, the one end of a damping element 32 is articulated, the other end of the hollow profile 21 of the rod-shaped stator 10 is articulated. With this damping element 32 it is achieved that the Einschwenkbewegung and the swiveling out of the support member 16 in the upper cabinet 1 or from the upper cabinet 1 takes place in a subdued manner, so that the support member 16, due to the action of the spring element 27, not fast in one of the two positions ,

Fig. 4 shows the support member 16, as already mentioned, in the fully out of the upper cabinet 1 swung-out and down position, Fig. 5 shows an intermediate position when pivoting the support member 16 from the pivoted position according to Fig. 4 in the pivoted into the upper cabinet 1 position Fig. 6 shows the support member 16 in the swung in the upper cabinet 1 state. It would also be conceivable to motorize this Einschwenk- and Ausschwenkvorgang by an electric linear drive, this could be arranged in a known manner, for example, between the first pivot lever 12 and the second pivot lever 13. This linear drive could then also be activated in a known manner by pressing a button.

In Fig. 7 is enlarged the storage of the first pivot lever 12 and the second pivot lever 13 in each first pivot bearings 14 in the first plates 11 of the support element 9 shown. As has already been mentioned, in the extension 25 of the first pivot lever 12 each have a longitudinal slot 29 is arranged. In these longitudinal slots 29, an axis 33 is slidably mounted, which axis 33 at the same time forms the pivot point 26 for the spring element 27 in the first pivot lever 12. The axis 33 penetrates a push rod 34, which is provided with a non-visible threaded portion which penetrates an adjusting screw 35 which is arranged non-displaceably in a pocket 36 in the first pivot lever 12. By turning the adjusting screw 35, the sliding rod 34 can be moved in the longitudinal direction via the threaded portion, not shown, whereby the axis 33 in the longitudinal slots 29 also moves and thus the pivot point 26 can be set for the spring element 27. As a result, the lever length between pivot point 26 and the first pivot bearing 14 can be changed, whereby the effective force on the support member 16 of the spring element 27 can be adapted to the respective weight. As a result, the pivoting in and out of the supporting part 16 in the upper cabinet or from the upper cabinet for the corresponding operator is facilitated.

With this solution according to the invention, a cabinet component is obtained, which has a very stable construction, which can be mounted in a simple manner in a wall unit and which can be used very flexibly. In addition, this cabinet installation part requires very little space and it can be equipped with various storage compartments.
