Description

Arrangement for moving a movable furniture part

The invention relates to an arrangement for moving a movable furniture part, in particular a pivotally mounted about an axis furniture part, with at least one ejection device for ejecting the movable Möbelteiis from a closed position to an open position, wherein the at least one ejection device comprises at least one energy storage, and a charging device for Loading the at least one energy storage by an opening or closing movement of the movable furniture part.

Such arrangements are e.g. from the applicant's application A 322/2012, which has an earlier priority date but has not yet been published. They have relatively complicated transmission mechanisms arranged between the at least one ejection device and the loading device for transmitting power during the loading of the at least one energy accumulator. Thus, e.g. Intermediate floors or Umienkvorrichtungen required that take up a lot of space. This is also unfavorable from an aesthetic point of view. Other publications defining the state of the art are WO 2012/000656, WO 2008/022673 and DE 20 2010 008 134.

Object of the present invention is to avoid the disadvantages described above and to provide a comparison with the prior art improved arrangement for moving a movable furniture part.

To solve this problem, the arrangement provides that between the at least one ejection device and the loading device is arranged at least one Bowden cable for transmitting power when loading the at least one force accumulator.

The term Bowden cable is a fixed term, which is defined eg by the DIN 71986. A person skilled in the art understands this to mean a movable machine element for transmitting a mechanical movement or a tensile force. Essentially, a Bowden cable consists of a so-called Bowden cable core (eg a steel wire or wire rope), which is surrounded by a flexible but pressure-tight shell in the pulling direction. The shell acts as a mechanical guide and as an abutment for the transmitted tensile forces, so that the Bowden cable can transmit forces via bends. An advantage of the use of a Bowden cable in connection with the subject matter of the present invention is that it occupies relatively little space and can be laid flexibly. It is also possible to "hide" it outwardly, for example, in a groove or the like According to an advantageous embodiment of the invention, it is provided that the loading device comprises at least one setting body and at least one setting contour, wherein the at least one standing body at least during one Due to the interplay of the at least one setting element and the at least one setting contour, different kinematic conditions can be achieved, In particular, a neutral area can also be realized in which the at least one setting element and the at least one setting contour Another major advantage that arises from the interaction of the at least one actuating body and the at least one control contour is the fact that the over between charging and non-charging of the energy store can be designed very gently.

Furthermore, it can preferably be provided that the at least one ejection device comprises at least one movable - preferably linearly movable - and by the at least one energy storage acted upon ejection element. It is advantageous if the at least one ejection device comprises at least one locking device for releasably locking the at least one ejection element against the action of the at least one energy accumulator. The locking device can be realized for example by means of a rocker arm. An alternative realization form of the locking device, which is not excluded from the idea of the invention, can also be based, for example, on a heart curve-shaped locking contour. Protection is also desired for a piece of furniture with a furniture body, at least one furniture part movably mounted in or on the furniture body, and at least one arrangement according to the invention for moving the at least one furniture piece. In this at least one furniture part may be both a furniture part that performs a rotational movement (this is the case, for example, in a furniture door or a furniture flap), as well as a furniture part, which is translationally movable (eg a drawer).

The use of the arrangement according to the invention is particularly suitable for wall cabinets which have an outer support structure and an inner body that can be raised and lowered with respect to this support structure. Here, the at least one Bowden cable can be arranged with the inner body raised up substantially between the inner carcass and the furniture body, so that it is not visible to the outside.

Further advantageous embodiments of the invention are defined in the dependent claims and together with further details and advantages of the invention in the context of the following description of the figures with reference to the figures. Showing:

Ejector for illustrating its mode of action.

With reference to the exploded view seen in Fig. 1 it can be seen that the

Ejecting device 3 of the arrangement 1 comprises a movable, more precisely a linearly movable, and acted upon by a force accumulator 4 in the form of a spring ejection element 12, said ejection element 12 has two over a limited distance 14 (see Fig. 7a to 7e) against each other movable parts 15 and 16, and wherein between the two parts 15 and 16, a compression spring 17 is arranged. The ejection element 12 is arranged linearly displaceable in a cuboid housing 33. Another essential component of the ejection device 3 is a locking device 18 for releasable locking of the ejection element 12 against being acted upon by the force accumulator 4, wherein this locking device 18 is a locking device that can be released by overpressures against the ejection direction. Core element of the locking device 18 is a rocker arm 19, wherein this rocker arm 19 on one arm has a latching projection 20 and on the other arm a Schrägfiäche 21 (see Fig. 7a to 7e), and is acted upon by a compression spring 22. The exact mode of operation of the ejection device 3 will be explained in more detail with reference to FIGS. 7a to 7e.

Essential components of the loading device 5 for loading the force accumulator 4 of the ejection device 3 are a base plate 29, on which a setting contour 8 and a two-armed lever 10 are rotatably mounted. The corresponding axes of rotation are provided with the reference numerals 30 and 32, respectively. On one arm of the lever 10 a Sielikörper 7 is provided in the form of a pressure roller, said adjusting body 7 runs on the control contour 8. A characteristic feature of the control contour 8 is a neutral section 9, in which the control element 7 and the control contour 8 move relative to one another such that the force accumulator 4 of the ejection device 3 is not charged (see also FIG.

For power transmission when loading the force accumulator 4 of the ejection device 3, a Bowden cable 6 is arranged between the ejection device 3 and the loading device 5. The Bowden cable 6 comprises a Bowden cable core 34, which is movably guided in a flexible outer shell 35. A first end 1 1 of the Bowden cable core 34 of the bow tie 6 is in operative connection with that arm of the two-armed lever 10, which does not have the adjusting body 7. The second end 13 of the Bowden cable core 34 of the Bowden cable 6 is connected to the rear part 16 of the ejection element of the ejection device 3.

And finally, the arrangement 1 comprises an actuator 23 for a furniture flap 2 (see, for example, Fig. 2), said actuator 23 on the one hand via a control arm 26 with the Furniture flap is connected and on the other hand with the charging device 5 is in operative connection. For this purpose, the base plate 29 is mounted laterally on the actuator 23. About a pin 31 is a movement coupling between the actuator arm 26 of the actuator 23 - and thus the furniture flap, which is connected to the actuator arm 26 - and the control contour 8 of the charging device 5 instead. The pin 31 is guided in guide tracks 27 and 28.

The mode of operation of the preferred exemplary embodiment of the arrangement according to the invention will now be explained in more detail with reference to the further figures:

FIG. 2 shows a side view of a piece of furniture 24 shown schematically, this piece of furniture 24 consisting of a furniture body 25 and a furniture part 2 movably mounted thereon in the form of a furniture flap 2 pivotally mounted about a horizontal axis. The furniture flap 2 is constructed of two superimposed and hinges (not shown) interconnected part flaps. The upper Teilkiappe is hinged on the one hand via hinges (not shown) to the furniture body and on the other hand connected to the actuating arm 26 of the actuator 23. In the closed state of the furniture flap 2, the lower part flap is loosely against a contact surface of the front part 15 of the ejection element, wherein the ejection element is releasably locked in this state against the action of the force storage device 4 via the above-described locking device.

Another great advantage of the present invention is that it is possible by means of the arrangement according to the invention to design the movable furniture part 2 without a handle. To open a user only a slight pressure on the front of the furniture part 2, in this case on the lower part of the folding flap flap exercise, whereby the ejection element of the ejection device is unlocked and the furniture part 2 so far pushes that the user the furniture flap 2 to the other Opening can comfortably reach behind. The initialization of this ejection movement is shown in FIG. By exerted on the lower part of the flap slight pressure (indicated by an arrow), the ejection element is suppressed, that is, in the direction of the action of the compression spring 4 opposite direction moves. Thereby, the rocker arm 19 of the locking device is unlocked (see Fig. 7b). Subsequently, as shown in Fig. 4, the stored energy in the energy storage 4 is released and thereby the ejection element of the ejection device 3 is ejected. As the front part 15 of the Ausstoßeiements abuts the Faltkiappe, it moves it from the Schließsteltung in an open position.

As already stated in the description of FIG. 1, the second end of the Bowden cable core 34 of the Bowden cable 6 is connected to the rear part 16 of the ejection element. This has the consequence that in the ejection movement, the Bowden cable core 34 is pulled through the flexible outer shell 35 a piece. One recognizes that e.g. because the first end 1 1 of the Bowden cable core 34 of the Bowden cable 6 has moved downwards.

In the course of the ejection movement, the folding flap 2 has been moved away from the furniture body 25 (typically 5 to 10 cm) so that the user can now easily grip behind the folding flap and continue to open it manually (compare FIG. 5). The actuator 23, softer connected to the flap 2, serves the purpose of the w eight force ^'the furniture flap 2 to compensate for in any position. This means that the folding flap 2 can be held in any position without falling back. From a comparison of Fig. 4 with Fig. 5 it is seen that the adjusting contour 8 rotates during the pivotal movement of the folding flap 2 in the opening direction in a clockwise direction. Due to its special shape, the adjusting contour 8 forces the two-armed lever 10 to execute an evasive rotational movement in the opposite direction of rotation. As a result, the first end 1 1 of the Bowden cable 34 of the Bowden cable 6 is pulled upward as a result. In addition, it should be noted that the two arms of the two-armed lever 10 have different lengths, resulting in a favorable balance of power.

Characterized in that at the first end 1 1 of the Bowden cable 34 of the Bowden cable 6 is pulled, moves the second end 13 of the Bowden cable 34 of the Bowden cable 6 and thus the ejector of the ejector 3 in the direction of the original position (see Fig. 2) back , At the same time, the compression spring 4 clamped firmly between the rear part 16 of the ejection element and the housing 33 of the ejection device 3 is charged. Overall, therefore, a part of the User for opening the folding flap 2 applied force to load the

Power accumulator 4 of the ejector 3 used. The transfer of this partial force takes place by means of the Bowden cable 6. The charging of the energy accumulator 4 takes place until the ejection element has again reached its locking position. At this time, the pressure roller 7 is located at the point 36 of the control contour 8 (see Fig. 6). At the same time, the folding flap 2 assumes a middle position between the closed position (see Fig. 2) and the fully open position (see Fig. 6). In the further opening movement of the folding flap 2 of the energy storage 4 is not charged further. This is achieved by arranging on the control contour 8 a neutral section 9 which is designed in such a way that the distance of the circumferential surface from the pivot point 30 between the points 36 and 37 does not increase any further. In a further rotational movement of the control contour 8, therefore, does not change the position of the two-armed lever 10th

When closing the folding flap 2, the control contour 8 and the lever 10 perform - in contrast to the opening of the folding flap - opposite movements. However, the first end 1 1 of the Bowden cable core 34 of the Bowden cable 6 remains in its position, since the ejection element is locked.

7a to 7e show a sequence of schematically illustrated cross-sectional views of the ejection device 3. Here, in FIGS. 7a and 7e, that state of the ejection device 3 can be seen, in which the ejection element is locked. FIGS. 7b to 7d show those states of the ejection device 3 which it assumes in FIGS. 3 to 5.

The locking of the ejection element of the ejection device 3 takes place thereby (see Fig. 7a to 7e), that the right arm of the rear part 16 of the ejection element about the rotation axis 38 rotatably mounted rocker arm 19 via the compression spring 22 with the locking projection 20 form-fitting against a corresponding Edge 39, which is located on the housing 33 of the ejector 3, is pressed.

The unlocking takes place thereby (see Fig. 7b), that the front part 15 of the ejection element over the distance 14 against the loading by the between the parts 15 and 16 arranged compression spring 17 on the rear

Part 16 is moved. At the front part 15 of the ejection element, an inclined surface is arranged (see also Fig. 1), which abuts in the course of unlocking a corresponding inclined surface 21 which is disposed on the second, not the locking projection 20 having, arm of the rocker arm 19. As a result, the oblique surface 21 having arm of the rocker arm 19 down and the opposite arm is moved against the action of the compression spring 22 upwards, and indeed until the locking projection 20 has overcome the arranged on the housing 33 edge 39. Now, the ejection element can move unhindered under the released energy of the energy accumulator 4 in the ejection direction (see Fig. 7c).

During the charging process (see Fig. 7a), the Ausstoßeiement is pulled by the Bowden cable 6 again in the direction of its original position, namely, until the latching projection 20 having arm of the rocker arm 19 under the action of the compression spring 22 back into the Can move locking division.
