Description

The present invention relates to a cabinet component with storage compartment, which can be inserted into a wall unit and can be swung out of an upper, retracted into the upper cabinet position in an extended from the upper cabinet and down offset position, mounted on both sides of the cabinet installation part two parallel pivoting lever are, on the one hand via the first pivot bearing on the wall unit are articulated and on the other hand articulated via second pivot bearing on the cabinet component, and at least one spring element is mounted, which is articulated on the one hand to one of the pivot lever in a pivot point and the other hand held on the top cabinet.

Such cabinet installation parts are known. They are used in particular in upper cabinets of kitchens, which often reach practically to the ceiling, so that the accessibility of these upper areas of the wall cabinets for a normal size person without climbing aids is not possible. With these cabinet installation parts you have the ability to bring the storage compartments held therein by pivoting down to a lower position, so that the accessibility is significantly improved.

For the compensation of the weight of such swing-down cabinet installation parts spring elements are provided. However, these spring elements are set only to a certain weight, with low loading of these cabinet components, the operator must apply a certain tensile force when swinging down, with large loads of these cabinet components, the operator must take down the not recorded by the spring excess weight when swinging down. This is perceived as disadvantage in such swing-down cabinet installation parts.

Subject of the DE 103 40 749 A1 is a hanging cabinet, which is held by a holder in the horizontal direction and in the vertical direction between an upper recessed position and a lower, preferred position movable. The holder has two pivot arms, which are mounted as a parallelogram in bearings. Further, the cabinet means for locking in the lower position and the holder has an adjustable gas spring as weight relief.

The object of the present invention is now to equip the cabinet mounting part so that the weight to be absorbed via the spring element can be adapted to the corresponding load.

According to the invention, the solution of this object is achieved in that the articulation point of the spring element is slidably disposed in the pivot lever and that for moving and locking the articulation point displacement means are mounted.

Due to the possibility of moving the articulation point of the spring element in the pivot lever, the distance of this articulation point can be changed to the first pivot bearing. As a result, the lever ratios change, whereby the force acting on the cabinet mounting part force can be adjusted to compensate for the weight. If the cabinet installation part is loaded with utensils, which have a large weight, the distance between the first pivot bearing and articulation point of the spring element can be increased on the pivot lever, if only little or lighter utensils are housed in the cabinet component, the distance can be reduced, the effective force the cabinet insert for swinging down is reduced. By this adjustment, the operation of this cabinet installation part for a corresponding person is easier and more pleasant because no additional effort needs to be operated.

Advantageously, the articulation point is mounted on a carriage, which carriage can be moved along guides, which are arranged on the pivot lever. This results in a simple structure and easy operation.

Advantageously, the displacement means are formed of a reversing lever, which is mounted on the pivot lever, and which lever is connected via steering levers with the carriage. By this lever, the carriage can be easily move.

A further advantageous embodiment of the invention is that the pivot lever, to which the articulation point is articulated, having an extension extending beyond the first pivot bearing extension, and that the guides are mounted for the carriage with the articulation point in this extension. By this configuration is achieved that both guides for the carriage as well as the displacement means can be accommodated in the pivot lever, which simplifies the structure.

In an advantageous manner, a spring element is attached to both sides of the cabinet mounting part, and these spring elements are gas pressure springs. The symmetrical arrangement of these gas springs results in a more uniform force on the cabinet component.

Advantageously, the articulation points are each attached to the upper pivot levers. This creates space for accommodating the spring elements or gas springs.

A further advantageous embodiment of the invention is that the second pivot bearings each have a bearing pin which are fastened to a plate-shaped element, on which the mounted on the pivot levers bearing element can be placed, and that the plate-shaped element can be fastened to the cabinet mounting part. As a result, these elements can be preassembled, the attachment to the cabinet component on site is simplified.

Also advantageously, the first pivot bearings each have a bearing pin, which are fastened to a further plate-shaped element on which the mounted on the pivot levers bearing element can be placed and is the other plate-shaped element fastened to the wall unit. This also results in simplifications in the installation site of this cabinet installation part.

A further advantageous embodiment of the invention is that the holder for the spring element is attached to the further plate-shaped element. Thus, all elements of this lever system can be preassembled, these can then attach as a component on site in a simple manner on the wall unit, after which the cabinet installation part is used, which greatly simplifies installation.

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

Out Fig. 1 is a schematic representation of a wall unit 1 can be seen in which for reasons of clarity, the door with which the upper cabinet 1 can be closed, and the upper cover are omitted. In this upper cabinet 1, the cabinet installation part 2 is with Of course, it would be conceivable to install even more storage compartments here. The cabinet installation part 2 is located in an upper retracted into the upper cabinet position in which the doors of the upper cabinet could be closed. In the lower part of the upper cabinet 1 could also be used in addition to the bottom 4 more storage compartments for the inclusion of utensils.

How out Fig. 2 it can be seen, the cabinet mounting part 2 can swing with respect to the upper cabinet 1 in a downwardly offset position. For this purpose, the cabinet mounting part 2 is held on both sides by two pivot levers 5 and 6. Each pivot lever 5 and 6 is articulated in each case via a first pivot bearing 7 on the upper cabinet 1. Each pivot lever 5 and 6 is articulated in each case via a second pivot bearing 8 on the cabinet mounting part 2. The two pivot levers 5 and 6 are each aligned in parallel, the first pivot bearing 7 and the second pivot bearing 8 form the vertices of a parallelogram, whereby the cabinet mounting part 2 from the upper retracted into the wall unit position, as shown in FIG Fig. 1 is shown, parallel in the downwardly offset position can be swung, as shown in Fig. 2 is shown.

The respective upper pivot lever 5 is provided with an extension 9 extending beyond the first pivot bearing 7. In this extension 9 guides 10 are mounted, in which a carriage 11 is slidably mounted and can be moved along these guides 10.

At this slide 11, the one end of a spring element 13 is articulated in the form of a gas spring in a pivot point 12. The other end of this gas spring 13 is hinged to the upper cabinet 1. By means of displacement means 14, which will be described in detail later, the carriage 11 can now be displaced along the guides 10 in the longitudinal direction of the pivoting lever 5. As a result, the distance of the articulation point 12, with which the gas spring 13 is connected to the carriage 11, can be adjusted to the first pivot bearing 7. In the position as they are in Fig. 2 is shown, the pivot point 12 is in a forward position, this means that the distance of the pivot point 12 to the first pivot bearing 7 am smallest is. This also means that as a result of the leverage, the spring force of the gas spring 13, with which the weight of the example provided with utensils cabinet insert part 2 is to be compensated, is the smallest. This setting is used when the utensils housed in the cabinet attachment 2 have a low weight.

In Fig. 3 the adjusting process is shown, with which the distance of the articulation point 12 to the first pivot bearing 7 can be increased. Via the displacement means 14, the carriage 11 is moved from the position as shown in FIG Fig. 2 is shown, moved along the pivot lever 5 in a rear position, the distance between the pivot point 12 and the first pivot bearing 7 is hereby increased.

In Fig. 4 is shown when the carriage and thus the pivot point 12 are in the rear position, that is in a position where the distance between the pivot point 12 and the first pivot bearing 7 is greatest. In this state, the greatest force acts, with which the weight of the cabinet installation part 2 and the utensils located thereon is counteracted. This adjustment is thus made when there are utensils having a large weight in the cabinet installation part 2.

From the side view according to Fig. 5 it can be seen that the carriage 11 is in the forward position, the distance between the pivot point 12 and the first pivot bearing 7 is the lowest, so that the force transmitted to the cabinet mounting part 2 by the gas spring 13 is small. The position shown here corresponds to that in Fig. 2 is apparent.

In the side view according to Fig. 6 is the carriage 11 in the rear position, this means that the pivot point 12 from the first pivot bearing 7 has a large distance. This ensures that the force acting on the cabinet insert part 2 force is greatest, the weight of the utensils, which are housed in the cabinet installation part 2, can be large, this is substantially compensated by the gas spring. This situation is similar to the one in Fig. 4 is shown.

For adjusting or for displacing the carriage 11 from one position to the other, the cabinet mounting part 2 is advantageously brought to a height such that the lever 5 is substantially perpendicular to the gas pressure spring 13. In this position, which is achieved by the operator by holding the cabinet mounting part 2, a displacement of the carriage 11 can be made without a substantial spring force of the gas spring 13 must be overcome.

Out Fig. 7 the carriage 11 can be seen, which along the guides 10 which are mounted in the pivot lever 5, is displaceable. Attached to this carriage is the pivot point 12, with which the gas spring 13 is pivotally connected to the carriage 11. The displacement means 14 for the carriage 11 comprise a reversing lever 15, which is pivotally held in a bearing block 16 which is fixed to the pivot lever 5. At the reversing lever 15 are articulated two steering levers 17. These two steering levers 17 are pivotally connected to the carriage 11. By deflecting the reversing lever 15 from a front position, shown in the Fig. 2 and 5 , in a rear position, shown in the Fig. 4 and 6 , moving the carriage 11 from a forward position (FIG. Fig. 2 and Fig. 5 ) in a rear position ( Fig. 4 and Fig. 6 ) receive. The reversing lever 15 can be frictionally held in the two positions, for example, in the lever 5, which is U-shaped, whereby an independent adjustment is prevented. For better usability of the lever 15 may still be provided with a handle 18.

Such as the Fig. 2 to 4 can be removed, the first pivot bearing 7 each have a bearing pin 18 which are fixed to a further plate-shaped member 19, on which the attached to the pivot levers 5 and 6 bearing element can be placed. This further plate-shaped element 19 is attached to the upper cabinet 1, for example by screwing. At this further plate-shaped element 19 and the holder for the gas spring 13 is mounted.

In the same way, the bearing journals of the second pivot bearing 8 are fastened to a plate-shaped element 20, to which the bearing element attached to the second pivoting levers 5 and 6 can be placed. This plate-shaped element 20 is also fastened, for example, by screwing on the cabinet mounting part 2. By this arrangement, the whole mechanism for pivoting the cabinet installation part 2 can be completely pre-assembled, the modules thus formed can then be installed in a relatively simple manner and with little effort on site in an existing wall unit 1.

In the embodiment shown here 2 gas pressure springs 13 are used on both sides of the cabinet insert part. Usually, the carriages 11, to which these gas pressure springs 13 are articulated, are brought into the same position during setting. This gives you two settings, one for a low weight, the other for a larger weight. But it is also conceivable that leaves one carriage 11 in the forward position, while the opposite carriage 11 is set in the rear position. This results in a force of the gas springs, which is suitable for an average weight of the cabinet installation part 2 with the utensils contained therein. This requires that the storage of the cabinet installation part is relatively stable, so that no tilting arises, this can be used for stabilization, for example, in the two second pivot bearings 8 for the upper pivot lever 5, as shown in the Fig. 2 to 4 is apparent.

With this arrangement according to the invention, a cabinet installation part for a wall unit can be moved from an upper retracted into the upper cabinet position in a displaced from the upper cabinet and down offset position, the weight counteracting spring force can be adjusted, which simplifies the operation and for the operator makes it more pleasant.
