Description

Method for moving at least one door leaf

The invention relates to a method for moving at least one door leaf relative to a fixed furniture body, the furniture body having at least one receiving space and at least one, preferably shaft-shaped, cavity and the at least one door leaf between a closed position in which the at least one door leaf is arranged in a closing plane and at least partially covers the at least one receiving space, and an open position in which the at least one door leaf releases the at least one receiving space and is arranged in an end position in the at least one cavity.

Such a method is already known from the prior art. The disadvantage here is that the movement of the door leaf is associated with a high expenditure of force for a user and the user has to exert force from different directions, which leads to a bumpy movement.

The object of the present invention is to at least partially remedy these disadvantages and to provide a method that is improved over the prior art, which is characterized in particular by a harmonious and intuitive movement sequence and less effort for a user and thus noticeably increases operating comfort.

This object is solved by the features of claim 1.

It is therefore provided that, in a first method step, the at least one door leaf, starting from the closed position, is preferably pivoted about an axis of rotation away from the at least one receiving space by means of a first ejection device, which can preferably be activated by pushing the at least one door leaf in the direction of the at least one receiving space wherein the first ejection device is arranged on the furniture body or on the at least one door leaf. As a result, the at least one door leaf is moved into an angular position from which the at least one door leaf can be moved further in the direction of the open position in a simple manner for the user. In a second method step, the at least one door leaf is moved into a partially open position, in which it is essentially arranged transversely to the closing plane and outside of the at least one cavity. In this partially open position, the receiving space is already accessible from the outside. Provision is preferably made for the at least one door leaf to be moved manually into the partially open position in the course of the second method step. This movement is associated with a comparatively small amount of force from a defined direction.

In a third method step, the at least one door leaf is moved from the partially open position to the open position, with at least one drive device and a second ejection device being loaded, preferably with the at least one drive device comprising a cable pull and/or a spring-loaded pivoting lever. It makes sense here for the at least one door leaf to be moved manually from the partially open position into the open position in the course of the third method step. This movement is also an intuitive movement for a user in a defined direction.

Since the at least one door leaf is in the open position, the receiving space is now freely accessible to the user. For example, a kitchen can be arranged in the accommodation space. In this case, the user can now carry out activities that are usually carried out in a kitchen.

If the user then wants to close the receiving space again, the at least one door leaf is ejected in a fourth method step, starting from the open position, by means of the second ejection device, which can preferably be activated by pressing the at least one door leaf in the direction of the end position, in the direction of the partially open position.

In a fifth method step, the at least one door leaf is moved into the partially open position by means of the at least one drive device. It makes sense that the at least one door leaf in the course of the fifth step in succession and / or simultaneously by at least two drive devices in the Partial open position is moved, wherein the drive devices are loaded in the course of the third step. For example, a first drive device can be a cable as disclosed in the applicant's application A 51123/2019 and a second drive device can be a pivoted lever pull-in device as disclosed in the applicant's application A 50495/2020 , act.

In a sixth method step, the at least one door leaf is moved from the partially open position into the closed position, preferably by means of a pivoting device and/or manually, with the first ejection device being loaded.

In the course of the fourth, fifth and sixth method step, the user does not have to exert any or only a small amount of force in order to move the at least one door leaf back into the closed position.

According to a preferred embodiment, it is provided that the first ejection device is also designed as a pivoting device, with which the at least one door leaf can be moved from the partially open position in the direction of the closed position, the pivoting device is loaded in the course of the second method step and the at least one door leaf in the course of the sixth method step is moved by means of the pivoting device and manually from the partially open position into the closed position.

For this purpose, the first ejection device can be designed, for example, as disclosed in the applicant's application A 51116/2019.

It makes sense for at least one damping device to be provided, with which a movement of the at least one door leaf into the partially open position is damped in the course of the fifth method step. In this way, the at least one door leaf can be braked shortly before moving into the partially open position in order to make the change of direction taking place in the partially open position particularly harmonious. It has turned out to be advantageous that the at least one door leaf is at least pivoted in the course of the first, second and sixth method step.

Alternatively or in addition, it has proven to be favorable that the at least one door leaf is moved linearly in the course of the third, fourth and fifth method step.

In this context, it makes sense for the at least one door leaf to be mounted on a carrier, preferably pivotably, and for the carrier to be displaced along at least one guide arranged in the at least one cavity in the course of the third, fourth and fifth method step.

According to a preferred embodiment, it is provided that the at least one door leaf is connected in an articulated manner to at least one further door leaf, the door leaves are arranged in a coplanar position in the closed position and are arranged essentially parallel to one another in the partially open position and the open position, and the door leaves in the course of the first, second and sixth method step carry out a pivoting and sliding movement.

In this context, it has proven to be advantageous that at least one running rail is arranged on the furniture body parallel to the closing plane and one of the door leaves is connected to the at least one running rail via a carriage and along the at least one running rail in the course of the first, second and sixth method step will proceed.

The running rail 24 is partially covered with a screen 37 .

The cavities 6 can be formed by two side walls 28, 29 and 30, 40 which are spaced apart from one another and arranged essentially parallel to one another, it being possible for the side walls 28, 29, 30, 40 to be connected to one another via connectors 34. The receiving spaces 5 can be arranged between the side walls 29 and 30 and 28 and a further side wall 27 .

In addition to the furniture 38, 39 shown in FIGS. 1 and 2, furniture is also conceivable that has only one movable furniture part that includes exactly one door leaf, or furniture with more than one movable furniture part and/or more than one movable furniture part. The present invention is described by way of example with reference to the pieces of furniture 38 and 39 with reference to FIGS.

FIG. 3 shows an exemplary embodiment of the method 1 for moving at least one door leaf 2, 3, 26 relative to a fixed furniture body 4, illustrated schematically using a flowchart. Method 1 comprises the following method steps:

In a first method step 8, the at least one door leaf 2, 3, 26, starting from the closed position, is ejected about a rotational axis by means of a first ejection device 9, which can preferably be activated by pushing the at least one door leaf 2, 3, 26 in the direction of the at least one receiving space 5 10 is pivoted away from at least one receiving space 5, preferably with the first ejection device 9 being arranged on the furniture body 4 or on the at least one door leaf 2, 3, 26.

In a second method step 11, the at least one door leaf 2, 3, 26 is moved into a partially open position, in which it is arranged essentially transversely to the closing plane 7 and outside of the at least one cavity 6.

In a third method step 12, the at least one door leaf 2, 3, 26 is moved from the partially open position to the open position, with at least one drive device 13, 14 and a second ejection device 15 being loaded, preferably with the at least one drive device 13, 14 having a cable and / or includes a spring-loaded pivoting lever. In a fourth method step 16, the at least one door leaf 2, 3, 26 is ejected in the direction of the partially open position, starting from the open position, by means of the second ejection device 15, which can preferably be activated by pressing the at least one door leaf 2, 3, 26 in the direction of the end position.

In a fifth method step 17, the at least one door leaf 2, 3, 26 is moved into the partially open position by means of the at least one drive device 13, 14. In a sixth method step 18, the at least one door leaf 2, 3, 26 is moved from the partially open position to the closed position, preferably by means of a pivoting device 19 and/or manually, with the first ejection device 9 being loaded.

Figures 4 to 16 show a further exemplary embodiment of method 1 for moving a door leaf 26 relative to a fixed furniture body, illustrated using a sequence of figures, with a piece of furniture 39 being shown schematically in a plan view in an upper part of the figures and in a lower part Force-displacement diagrams are shown.

The piece of furniture 39 comprises a receiving space 5 arranged between the side walls 29 and 30 and a hollow space 6 arranged between the side walls 30 and 40.

The door leaf 26 can be pivoted about an axis of rotation 10 .

Two force-displacement diagrams are shown in each case in the lower part of the figures, with the diagram on the left showing the effective force 41 during a movement of the door leaf 26 between the closed position, in which the door leaf 26 is arranged in the closing plane 7, and the partially open position, in which the door leaf 26 is arranged substantially parallel to the cavity 6, over the pivot angle path 43 shows. The diagram on the right shows the effective force 42 during a movement of the door leaf 26 between the partially open position and the open position, in which the door leaf 26 is arranged in the end position in the cavity 6, over the travel path 44. In the figure 4 the closed position of the door leaf 26 is shown. An energy accumulator of the first ejection device 9, which is arranged on the furniture body 4 in the illustrated case, is charged, which is indicated schematically by means of a rectangle filled with black color.

In a first method step 8 , starting from the closed position, the door leaf 26 is pivoted away from the receiving space 5 about an axis of rotation 10 by means of the first ejection device 9 that can be activated by pushing the door leaf 26 in the direction of the receiving space 5 .

FIG. 5 shows the overpressure position and FIG. 6 shows the position of the door leaf 26 after it has been ejected. During ejection, the energy store of the first ejection device 9 is discharged, which is indicated by the fact that the rectangle in FIG. 6 is no longer filled.

In a second method step 11, the door leaf 26 is moved manually into a partially open position, in which it is arranged essentially transversely to the closing plane 7 and outside of the at least one cavity 6. The partially open position is shown in FIG. All provided drive devices 9, 13, 14 and 15 are discharged in the partially open position. In order to transfer the door leaf 26 from the ejected position shown in FIG. 6 into the partially open position, the user must exert a force that is essentially constant after an initial increase.

In a third method step 12, the door leaf 26 is moved from the partially open position to the open position, with two drive devices 13, 14 and a second ejection device 15 being loaded, preferably with the drive device 13 comprising spring-loaded pivoted levers and the drive device 14 comprising a cable pull.

First, an energy accumulator of the drive device 13 is charged (compare FIG. 8), then at least a part of an energy accumulator of the drive device 14 (compare FIG. 9) and finally an energy accumulator of the second Ejection device 15, so that in the open position, which is shown in Figure 10, all provided drive devices 13, 14 and 15 with the exception of the first ejection device 9 are loaded.

If the user of the item of furniture 39 now wants to move the door leaf 26 back from the open position to the closed position, the door leaf 26 can be pushed in the direction of the partially open position in a fourth method step 16 by means of the second ejection device 15, which can be activated by pressing the door leaf 26 in the direction of the end position be expelled. FIG. 11 shows the overpressure position in the cavity 6 and FIG. 12 shows an intermediate position in which the door leaf 26 is arranged in the cavity 6 after being ejected.

Starting from this intermediate position, the door leaf 26 is moved into the partially open position in a fifth method step 17 by means of the drive devices 13 and 14, in succession by the drive device 14, which can also already be active during ejection (see Figure 13) and then by the Drive device 13, through which the door leaf 26 is transported into the defined partially open position (see Figure 14). In a sixth method step 18, the door leaf 26 is moved manually from the partially open position to the closed position, with the first ejection device 9 being loaded in a last pivoting angle range before the closed position is reached (compare FIGS. 15 and 16).

Thus, the door leaf 26 is back in the starting position and can be opened again.

FIGS. 17 to 30 show a further exemplary embodiment of method 1.

In this case, the piece of furniture 38 comprises two hinged door leaves 2, 3. The piece of furniture 38 also comprises a receiving space 5 arranged between the side walls 27 and 28 and a cavity 6 arranged between the side walls 28 and 29. In a first method step 8, the door leaves 2, 3 are pivoted away from the receiving space 5 about an axis of rotation 10, starting from the closed position shown in FIG.

In this case, the first ejection device 9 is arranged on one of the door leaves 2, 3. The overpressing position is shown in FIG. 18 and the kinked position assumed after ejection is shown in FIG.

In a second method step 11, the door leaves 2, 3 are moved into a partially open position, in which the door leaves 2, 3 are arranged essentially transversely to the closing plane 7 and outside of the at least one cavity 6. The door leaves 2, 3 are also arranged essentially parallel to one another and quasi as a package.

FIG. 20 shows an intermediate position. An energy accumulator of the first ejection device 9 is discharged both in the bent position assumed after the ejection and in the intermediate position. Up to the intermediate position, the process runs analogously to the process according to FIGS.

One difference comes into play as the process progresses: in the case of the double-leaf arrangement, the first ejection device 9 is also designed as a pivoting device 19, with which the door leaves 2, 3 can be moved from the partially open position back towards the closed position at a later point in time. The pivoting device 19 is now loaded in the course of the second method step 11 with a continued movement from the intermediate position shown in FIG. 20 into the partially open position shown in FIG. 21, which is associated with an increase in force.

In a third method step 12, the door panel assembly is manually moved from the partially open position to the open position, with a drive device 14 and a second ejection device 15 being loaded, preferably with the drive device 14 comprising a cable pull. FIG. 22 shows an intermediate position of the door leaves 2, 3 around the cavity 6, in which an energy accumulator of the drive device 14 is loaded. FIG. 23 shows the end position, in which an energy accumulator of the second ejection device 15 is also loaded.

In a fourth method step 16, the door panel assembly is ejected back in the direction of the partially open position, starting from the open position, by means of the second ejection device 15, which can be activated by pressing the door panel assembly in the direction of the end position. FIG. 24 shows the overpressing position and FIG. 25 shows an ejection position after the end of the ejection process.

In a fifth method step 17, the door leaves 2, 3 are moved into the partially open position by means of the drive device 14.

In this exemplary embodiment, at least one damping device 20 is provided, with which a movement of the door leaf assembly into the partially open position is damped in the course of the fifth method step 17, specifically in a path section immediately upstream of the partially open position. This is shown in FIG.

In a sixth method step 18, the door leaves 2, 3 are moved first by means of the pivoting device 19 and then manually from the partially open position to the closed position, with the first ejection device 9 being loaded in a last path section immediately before the closed position (compare Figures 28, 29 and 30).

The door leaves 2, 3 are in the closed position, which is shown in Figures 17 and 30, in a coplanar position and in the partially open position and the open position arranged essentially parallel to one another, and in the course of the first, second and sixth method step 8, 11, 18 a pan-slide movement.
