Description

Ejecting device for a movable furniture part

The invention relates to an ejection device for a movable furniture part, comprising at least one ejection element for ejecting the movable furniture part from a closed position to an open position, at least one ejection force memory for applying force to the at least one ejection element when ejecting the movable furniture part from the closed position to the open position, at least one locking device for locking the at least one ejection element against the application of force by the at least one ejection force accumulator, wherein the at least one locking device can be unlocked by overpressing the movable furniture part in an overpressure position arranged in the closing direction behind the closed position. The invention further relates to furniture with a furniture body, at least one movable relative to the furniture body furniture part and at least one such ejection device.

An ejection device according to the preamble of claim 1 is known for example from WO 2013/106873 A1. A fundamental problem with this ejection device is that you want to prevent the open position in a closed position in a movement of the movable furniture part that the locking device is inadvertently unlocked again and the movable furniture part is ejected again from the ejector from the closed position to the open position.

To remedy this problem, some solutions are already known in the art. In WO 2013/106873 A1, for example, a push-through protection is realized in that a movement of the movable furniture part into the overpress position is prevented by a blocking element when the movable furniture part reaches the closed position.

However, this solution has two disadvantages: on the one hand a part of the energy available for the closing movement of the movable furniture part energy must be diverted to trigger by pressure protection. However, this is in contradiction to the desire to realize a harmonic and gentle closing movement, as more energy must be provided for the closing movement than would actually be necessary. On the other hand, there is the danger that a user is unaware that the ejection device is equipped with a push-through protection and damages the blocking element or the push-through protection by incorrect operation. The object of the present invention is therefore to provide an ejection device according to the preamble of claim 1 with a comparison with the prior art improved press-through protection, in which in particular the disadvantages described are avoided. Another object of the invention is to provide a piece of furniture with such an ejection device according to the invention.

These objects are achieved by the features of claims 1 and 14.

In the ejection device according to the invention, it is thus provided that at least one is operatively connected to the at least one locking device switching element is provided, which at least one activation position, in which the at least one locking device is unlocked, and at least one deactivation position, in which the at least one locking device untriegelbar is, wherein the at least one switching element during ejection of the movable furniture part from the closed position into the open position and / or by unlocking the at least one locking device in the at least one deactivation position is movable.

Characterized in that the at least one switching element during ejection of the movable furniture part and / or by unlocking the at least one locking device in the at least one deactivation position is movable, and thus the locking device is not unlocked, it is ensured that the push-through, ie inadvertent unlocking of the locking device , is activated by the opening movement of the movable furniture part and not more, as provided in the prior art, by the closing movement of the movable furniture part. So no part of the closed energy must be diverted to activate the push-through protection.

Furthermore, it is no longer prevented that the movable furniture part is moved into the overpressure position. The solution according to the invention permits a movement of the movable furniture part from the closed position into the overpressure position. However, it is ensured by the at least one switching element in the at least one deactivation position-at least at the beginning of the movement of the movable furniture part into the overpressure position-that the at least one locking device can not be unlocked during this movement. Mechanical damage to the push-through protection is excluded. The movement of the at least one switching element into the at least one deactivation position when the movable furniture part is ejected from the closed position into the open position can be realized, for example, by providing a coupling device via which the at least one switching element can be indirectly or directly coupled to the at least one ejection element , Preferably, wherein the coupling device comprises a driver and a stopper contour, particularly preferably wherein the stopper contour as a slot in which the driver is movably mounted comprises. In this way, therefore, a movement of the ejection element is used to move at least one switching element in the at least deactivation position. But this does not necessarily have to be the case. Just as well, it is also conceivable that the at least one switching element is indeed moved during the ejection of the movable furniture part in the at least one deactivation position but independent of the movement of the at least one ejection element. According to a preferred embodiment of the invention, it is provided that the at least one locking device has at least one unlocking device, which comprises at least one coupling device for coupling the at least one unlocking device with the at least one switching element. In this case, the at least one coupling device of at least one unlocking device having at least one contact point, wherein the at least one coupling device contacted the at least one switching element in the at least one activation position on the at least one contact point and at least at least one contact point contactless to at least one switching element in the at least a deactivation position is formed. In this case, the at least one switching element of the at least one activation position provides a Wderlager, on which the at least one unlocking device can be supported for unlocking the locking device. In the at least one deactivation position of the at least one switching element, this abutment is not present, so that the at least one unlocking device engages in the void.

Furthermore, it has been found to be advantageous that at least one rear part device is provided, via which the at least one switching element after the ejection of the movable furniture part from the closed position to the open position or the unlocking of the at least one locking device from the at least one deactivation position in the at least one Activation position is movable. At which time or at which position of the movable furniture part relative to the furniture body which moves at least one rear part device after ejection or unlocking of at least one switching element from the deactivation position in the activation position is not crucial. It can thus also be provided that the movement of the at least one switching element from the at least one deactivation position into the at least one activation position takes place, for example, only when the closed position of the movable furniture part is reached again. The movement of the at least one switching element does not have to be done by a rear part device. In principle, it would also be conceivable for the user to manually move the at least one switching element back into the at least one activation position.

If at least one rear part device is provided, however, it proved to be favorable that the at least one rear part device comprises a timing element, via which the at least one shift element with a time delay after the ejection of the movable furniture part from the closed position to the open position or the unlocking of at least one Locking device from the at least one deactivation position in the at least one activation position is movable, preferably wherein the timing element at least one energy storage and at least one damper, which counteracts the at least one energy storage comprises.

Alternatively or additionally, it can be provided that the at least one rear part device comprises a detection device for detecting a relative position of the movable furniture part with respect to a furniture body and the at least one switching element of the at least one rear part device in response to a predetermined detected by the detection device relative Position from the at least one deactivation position in the at least one activation position is movable. By "relative position of the movable furniture part" with respect to the furniture body, for example, in the case of a drawer as a movable furniture part, a certain distance of the front panel of this drawer to the front side of the furniture part may be meant Door is formed, which comprises at least a first door leaf and a second door leaf, with "relative position of the movable furniture part" with respect to the furniture body and a certain angular position of the two door leaves are meant relative to each other. A further advantageous embodiment of the invention consists in that the at least one locking device comprises at least one lever arm which is pivotable is stored, and / or positive and / or non-positively lockable. A positive connection can be realized, for example, by a latching projection which engages behind a bolt or the like. Furthermore, it has been found to be advantageous that a transmission device is provided which is arranged between the at least one ejection force accumulator and the at least one ejection element, preferably wherein the translating device comprises at least one rolling element and at least one control contour on which the at least one rolling element is movable. The case that the translation device comprises a rolling body and a setting contour is particularly advantageous since a certain sequence of movements of the at least one ejection element can be realized via the design of the setting contour. By arranging differently inclined surfaces on which the rolling body runs in succession, for example, different acceleration and braking phases can be realized.

In a special way, it is appropriate to use the ejection device in conjunction with a movable furniture part, which is designed as a folding door or folding-sliding door, wherein the folding door or folding-sliding door comprises at least a first door leaf and a second door leaf, and the at least one ejection element is designed to open the folding door or folding / sliding door from a closed position in which the at least two door leaves are arranged in a common closing plane into an open position in which the at least two door leaves enclose an angle that is not equal to 180 ° to launch.

In this case, it is further appropriate that the ejection device has at least one fitting part for mounting the ejection device on the first door leaf and the at least one ejection element is supported on the at least one fitting part, and the at least one ejection element has at least one device for coupling the at least one Having ejection element with the second door, at least when folding the folding door or folding-sliding door from the closed position to the open position.

By this embodiment, it is ensured that the ejection or buckling of the folding door or folding-sliding door between the two leaves, and not between the folding door or folding door and the furniture body. This has two major advantages: first, a smaller lever length is required if the at least one ejection element is designed as a lever. This can be a lower compared to the prior art Design can be achieved. On the other hand, always the same opening angle between the door leaves when ejecting, regardless of the dimensions of the door leaves.

In the event that an unlocking device is provided for the locking device, it is likewise not absolutely necessary that the unlocking device forms a contact with the furniture body for unlocking. Rather, it can also be provided that the unlocking device is connected or connectable at least when unlocking the at least one locking device with the first door leaf and the second door leaf, so that the unlocking device can detect a relative change in angle of the two door wings when unlocking the at least one locking device. In this way, the ejection device can be arranged at any point between the two door leaves. Otherwise, one would have to make sure that the ejection device is arranged on the two door leaves so that they have a small distance from an end face of the furniture body.

As mentioned above, protection is also desired for a piece of furniture with a furniture body, at least one furniture part movable relative to the furniture body, in particular at least one folding door or folding sliding door, and at least one ejection device according to the invention for ejecting the at least one movable furniture part from a closed position an open position, preferably wherein the at least one movable furniture part is designed as a folding door or folding-sliding door and the furniture body has a, in particular shaft-shaped, cavity for receiving the at least one folding door or folding sliding door in a folded position. In connection with the present invention, it is particularly appropriate to provide a drive device which is designed to automatically transfer the at least one movable furniture part from the open position into the closed position. Then, two cases can be distinguished from each other, namely on the one hand a first case in which the movable furniture part is manually moved immediately after ejection back to the closed position by a user, and on the other hand, a second case in which the at least one movable furniture part automatically transferred to the closed position. In the first case, the push-through protection is activated according to the invention in that the at least one switching element is located in the at least one deactivation position, at least at the beginning of the movement of the movable furniture part into the closing or overpressing position, whereby the at least one locking device is unlockable. In the second case, on the other hand, it is not necessary at all to provide push-through protection to have available, since the drive device will always move the movable furniture part with the same force in the closed position. By a tailor-made design of this force, a movement of the movable furniture part from the closed position to the overpress position can be avoided without the need for a push-through protection would be necessary. In other words, the present invention particularly covers the case of "emergency closing" in the sense that a user changes his mind regarding the opening desire and wishes to close the movable furniture part immediately after ejection or even ejection Push-through protection always active to the effect that the locking device is unlocked.

To arrange the folding-sliding doors 2 within the furniture body 15 are cavities 26, which are formed shaft-shaped provided.

At least in that part of the furniture 25 which can be covered by means of the folding-sliding doors 2, a kitchen 28 is arranged with an example, drawers comprising base cabinet and wall units.

One of the two door leaves 19 and 20 of the folding sliding doors 2 is arranged in each case articulated on a support. This door is provided with the reference numeral 19. The two door leaves 19 and 20 are further connected by hinges 30 (see Figure 1c) hinged together. The one door leaf 20 which is not hinged to the carrier is connected to a carriage 31 in connection, which is movably mounted along a rail 32. The rail 32 is arranged in the upper region of the furniture body 15.

The three spatial directions are provided with the reference numerals 6 (depth), 34 (width) and 33 (height).

Between the two door leaves 19 and 20 of the folding-sliding doors 2 is in each case an ejection device 1 for ejecting the folding-sliding doors 2 from a closed position, in which the two door leaves 19 and 20 are arranged in a common closing plane, in an open position , in which the two door leaves 19 and 20 enclose an angle 21 not equal to 180 ° to each other, arranged. These ejectors 1 partially cooperate with an end face 29 of the furniture body 15.

FIGS. 2 a to 12 b describe a first preferred exemplary embodiment of the ejection device 1. In Figures 13a to 13c, a second Embodiment of the ejection device 101 described. In Figs. 15a to 28f, a third embodiment of the ejection device 201 will be described.

Figures 2a to 2c show the ejection device 1 according to the first preferred embodiment in the locked closed position, wherein a section of the folding-sliding door or hingedly interconnected via the center hinges 30 door leaves 19 and 20 is shown schematically. The hinge axis of the center hinges 30 is provided with the reference numeral 35. The ejection device 1 is connected on the one hand via a fitting part 40 (see FIG. 2c) and on the other hand via fitting parts 24 with the door wings 19 and 20.

On the one door leaf 19, a first part of the ejection device 1 and on the other door 20, a second part of the ejection device 1 is arranged. The first part of the ejection device 1 comprises an ejection force accumulator 4 with two compression springs, which are each arranged on a stabilization device 38 (see also FIG. 3). The stabilizing devices 38 prevent buckling of the compression springs during compression. The stabilizing devices 38 are each disposed between a base 37 and a slider 36. The base 37 is fixedly connected to the door leaf 19 via a base plate 40. The slider 36 can be displaced relative to the base plate 40, on the one hand under the influence of an energy stored in the compression springs of the ejection force memory 4 and on the other under the influence of a manual action on the ejection device 1 by folding the door wings 19 and 20. Der Slider 36 has a first end, in which the stabilizing devices 38 are supported, and an opposite second end, on which two rolling elements 17 are rotatably mounted about an axis 41 (see also FIG. 3). The rolling elements 17 are each supported on a rotatably mounted about an axis 47 adjusting contour 18 from. In order to prevent lifting of the slide 36 of the fitting 40, another rolling element 52 is arranged on the axis 41 between the two rolling elements 17, which is mounted displaceably limited in a groove 53 of a component 42. The component 42 is arranged between the two actuating contours 18. The control contours 18 and the rolling elements 17 form a transmission device, which is arranged between the ejection energy accumulator 4 and two ejection elements 3. The Ejection elements 3 are positively coupled in their movement with the control contours 18. This means that the ejection elements 3 also execute such a rotation upon rotation of the setting contours 18 about the axis of rotation 47. Furthermore, the ejection elements 3 each have at least one device for coupling the ejection elements 3 with one of the door leaves 19 or 20. In detail, this device for coupling consists of a, preferably bolt-shaped, end portion 23, which is slidably mounted in a groove 54 (see also Figure 3) of a fitting part 24. By a rotation of the ejection elements 3 about the rotation axis 47, the door leaf 20 is thus pivoted relative to the door leaf 19 about the rotation axis 35. Conversely, a relative movement of the door leaves 19 and 20 to each other and the ejection elements 3 in a rotary motion.

In summary, the translation device serves inter alia to implement a linear movement of the slide 36 in a pivoting movement of the ejection elements 3, and vice versa. In the implementation of the linear movement of the slider 36 in a pivoting movement of the ejection elements 3 of the ejection force memory 4 is discharged. In the reverse direction, that is, when a relative movement of the door leaves 19 and 20 or the fitting parts 40 and 24 relative to each other into a linear movement of the slider 36, the ejection force memory 4 is loaded.

Due to the configuration of the setting contours 18, the movement of the ejection elements 3 can also be controlled precisely. In this way, for example, initially an acceleration phase can be achieved at the beginning of the ejection process. This can then be followed by a braking phase before the loading of the ejection force memory 4 takes place.

In order to achieve a compact design of the ejection device 1, in the fitting part 49 and the door leaf 19 each recesses 46 (see also Figure 3) are formed, which can accommodate the control contours 18 in the course of their pivoting at least partially.

The ejection device 1 further comprises a locking device 5 for locking the ejection element 3 against the application of force by the ejection force accumulator 4. The locking device 5 comprises a lever arm 16, which is pivotally mounted about an axis of rotation 57 on the slide 36. The locking device 5 is pressed by a hold-down device in the direction of the fitting part 40 (see also the following figures). The hold-down device comprises a spring 68 which is connected on the one hand directly or indirectly to the fitting part 40, wherein this connection can be made via the base 37 as in the case shown. On the other hand, the spring 68 is connected to the end of a lever 67, wherein at the end of the lever also a transverse pin is arranged, which acts on a projection 45 of the locking device 5. The spring 68 is designed as a tension spring and has a slight bias. If the locking device 5 is pivoted away from the fitting part 40, then the spring 68 is more strongly tensioned and exerts a greater force in the direction of the fitting part 40. As a result, the locking device 5 in each position tends to move in the direction of the fitting 40. The hold-down device may alternatively or additionally be formed by an axial spring in the vicinity of the axis of rotation 57.

The lever arm 16 is designed in two parts in the illustrated case (see also Figure 3). Just as well, the lever arm 16 could also be made in one piece. At a free end of the lever arm 16, a latching projection 44 is formed, which can be positively and non-positively latched to a pin 43. The bolt 43 is fixedly arranged on the base plate 40. Instead of the illustrated locking solution, any other locking solutions are conceivable.

For unlocking the locking device 5, two unlocking devices 10 are provided. These are rotatably mounted on the lever arm 16 about a rotation axis 48. Furthermore, the unlocking devices 10 have a free end, which can contact via a contact point 51 with the end face 29 of the furniture body 15 in contact (see also the following figures).

The ejection device 1 also comprises as an essential element a standing with the locking device 5 in Wrkverbindung switching element 7, which has an activation position in which the locking device 5 is unlocked, and a deactivation position in which the locking device 5 is unlockable, wherein the switching element 7 at Ejecting the movable furniture part 2 from the closed position into the open position in the deactivation position is movable. Specifically, the switching element 7 is designed in the illustrated case as a slide, which is held linearly displaceable in the base plate 40 (see in particular Figures 2c and 3).

There is provided a coupling device, via which the switching element 7 with the ejection elements 3 is indirectly coupled, wherein the coupling device comprises a driver 8 and a stop contour 9 in the form of a slot in which the driver 8 is movably mounted. In the present case, the driver 8 is designed as a pin which is mounted in the slide 36, on which the ejection force accumulator 4 attacks. The slot 9 is formed in the switching element 7. But just as well, the slider 36, the slot 9 and the switching element 7 include the driver 8. In addition, the coupling device can also be designed completely different.

The unlocking devices 10 furthermore each have a coupling device 1 1 for coupling the unlocking devices 10 with the switching element 7. Specifically, these coupling devices 11 each comprise a contact point 12, wherein the coupling devices 1 1 contact the switching element 7 in the activation position via the contact points 12 and are formed contactlessly to the switching element 7 in the deactivation position. In order to move the switching element 7 back out of the deactivation position after the ejection of the folding-sliding door 2 from the closed position to the open position into the activation position, a rear-part device is provided. In this case, the rear part device comprises a timer, via which the switching element 7 is moved with a time delay in the activation position. The timer comprises a force accumulator 13 and a damper 14, which counteracts the energy accumulator 13. In particular, from the figure 2c shows that the energy storage 13 comprises two compression springs, which are arranged between a first end of the switching element 7 and the base plate 40. The damper 14, which is designed as a fluid damper with a piston-cylinder unit, is arranged between a second end of the switching element 7 and the component 39. This means that the slide 7 is acted upon from one side by the energy storage 13 and from the other side by the damper 14.

In the locked rest position of the ejection device 1, a balance between the energy accumulator 13 and the damper 14 is to the effect that the energy accumulator 13 is discharged and the damper 14 is depressed. This position is shown in FIGS. 4a to 4c and in FIG. 12a. The locking device 5 is locked in this position. The Unlocking device 10 contacts on the one hand via the contact point 51 an end face 29 of the furniture body 15 and on the other hand via the contact point 12, the switching element 7 (see Figure 4c). If one moves the ejection device 1 or the associated movable furniture part 2 in a closed position in the closing direction 6 overpressure position (see FIGS. 5a to 5c), the unlocking device 10 unlocks the locking device 5 by exerting force on the connecting shaft 48 Detent projection 44 relative to the locking pin 43 enough clearance to lift the positive and frictional connection.

Subsequently, a user releases the ejection device 1 or the movable furniture part 2 connected thereto (compare FIGS. 6 a to 6 c). As a result, the force stored in the ejection force accumulator 4 can escape, whereby the slider 36 executes a linear movement. About the driver 8, which abuts on a first stop surface 58 of the slot 9 after a short time, the switching element 7 is moved with. Thereby, the switching element 7 is pulled away from the unlocking device 10 and the contact point 12 of the coupling device 11 (see in particular Figure 6c). At the same time, the energy accumulator 13 of the timer, which acts on the switching element 7, compressed, and the damper 14 relaxes.

The slider 36 subsequently exerts a force on the actuating contours 18 and thus on the ejection elements 3 via the rolling bodies 17. The control contours 18 and the ejection elements 3 are thereby pivoted about the axis of rotation 47. By the coupling devices 23, 24 of the ejection elements 3, the fitting parts 24 and the associated door leaf 19 and 20 are pivoted about the axis of rotation 35, starting from a position in which the door leaves 19 and 20 are arranged in a common closing plane, in a position in which the door leaves 19 and 20 at an angle not equal to 180 ° to each other include (see in particular Figure 6a).

The ejection movement is terminated by that the ejection force accumulator 4 is completely discharged. The position which the ejection device 1 occupies at this time is shown in FIGS. 7a to 7d. As can be seen in particular from FIG. 7c, the rolling element 17 is in this position in a minimum 60, which is encompassed by the setting contour 18. Usually, the user would like to open the movable furniture part 2 now. For this purpose, he exerts a force 61 on the movable furniture part 2. Is it the movable one Furniture part 2 to a folding-sliding door, then the folding-sliding door is moved by the exercise of force in the direction of a position in which the folding-sliding door is folded together. As a result, the ejection elements 3 or the associated actuating contours 18 are further pivoted about the axis of rotation 47. Since the control contours 18 rest against the rolling elements 17 of the slider 36, the slider 36 is moved back in the direction of the starting position, which the slider 36 has assumed in the locked state. As a result, the ejection force memory 4 is subsequently recharged.

During this loading movement, the rear part device becomes effective. This means that the force stored in the energy storage device 13 is released again and the switching element 7 is moved back against the action of the damper 14 in the original activation position. The push-through protection, which was activated during the ejection of the movable furniture part 2 from the closed position into the open position, is thus deactivated again in the course of a loading movement of the ejection device 1.

Figures 8a and 8b show the folded state of the ejection device 1 and the movable furniture part 2. Starting from this position, the furniture part 2 can now be moved into a cavity 26 in the furniture body 15 into it. The ejector 1 assumes a quasi-locked state in this position. This condition is due to the fact that the ejector 1 must be stowed space-saving as possible. This means that the unlocking device 10 is actually in a position in which the locking device 5 would be unlocked. This is due to the fact that the unlocking device 10 is "squeezed" between the switching element 7 and the door leaf 20. However, if the folding / sliding door 2 is unfolded again, the locking device 5 is immediately locked again namely by the control contours 18 is blocked.

FIG. 9 shows the ejection device 1 in an intermediate position during the transfer to the closed position, starting from the folded position according to FIG. 8b. It can be seen that the locking device 5 is locked. A force 62 is exerted on the ejection device 1 or the associated door leaves 19 and 20. According to a preferred embodiment of the invention, this force 62 is provided by a drive device 30, which is designed to automatically transfer the movable furniture part 2 into the closed position. The drive device 30 may be, for example, the center hinges which connect the door leaves 19 and 20 with each other. But it can also be alternatively or additionally provided a separate drive device. In addition, in addition, a drive device 49 can also be provided, which transfers the door package from the cavity 26 to a position outside the cavity 26. The drive device 30 can also be divided into two parts, in that a first part causes a buckling of the door package from the folded position into an intermediate position and a second part causes a transfer from the intermediate position to the final closed position. Since the force provided by the drive device 30 can be accurately adjusted, the movable furniture part 2 will always move to the closed position at the same speed. A push-through protection is not necessary in this case, since the force can be dimensioned so that the movable furniture part is no longer moved from the closed position into the overpressure position.

However, it can also happen that the ejection device 1 was triggered inadvertently, or that a user immediately after unlocking or ejecting changes his mind and would like to immediately transfer again the movable furniture part 2 in the closed position. This situation is also referred to as "emergency closing." This scenario is illustrated in Figures 10a to 10c, 11 and 12b, ie, a user manually exerts a force 63 on the ejector 1. The ejector 4 is thus immediately recharged by the rolling elements 17 are moved back in the opposite direction to the setting contours 18, and the locking device 5 is moved in the direction of the locking position, but in this situation the push-through protection is still active by the timer of the return device The unlocking device 10 is thus formed contactlessly with respect to the switching element 7. If the user doses his force 63 too high, the movable furniture part 2 is moved further into the overpressure position via the closed position (see FIG. 11) can not be supported on the switching element 7, lead bt the locking device 5 locked. This means that the locking device 5 is unlockable. Only after a certain time, the switching element 7 is moved back into the activation position. However, the user usually exerts no more force on the ejection device 1. The ejector 1 remains locked.

Figures 13a to 13c show a second preferred embodiment of

Ejector 101, in the locked closed position (Figure 13a), in the

Overpressure position (Figure 13b) and in a position immediately after unlocking (Figure 13c). An essential difference in this embodiment is that the unlocking device 110 when unlocking the locking device 5 with the first door leaf 19 and the second door 20, or the two fitting parts 40 and 24, is connected, so that the unlocking device 110 is a relative change in angle of the two Door leaf 19 and 20 can detect each other when unlocking the locking device 5. This may be, for example, a cable 55, which is taut in the closed position between an end 69 of the unlocking device 110 and a connecting point 56 on the fitting part 24. If now the ejection device 101 is moved from the closed position into the overpressure position, the unlocking device 10 is moved in the direction of the locking device 5. Since the unlocking device 110 is supported at the same time on the switching element 7 described in detail in connection with the first exemplary embodiment, an unlocking of the locking device 5 is brought about. So there is no contact with the furniture body 15 required to effect unlocking. This has the great advantage that the ejection device 101 can be arranged at any point of the movable furniture part 2.

Figures 14a and 14b show a furniture 27 in the form of an upper cabinet for the kitchen, which can be closed by a folding flap 22 to the outside. The folding flap 22 is formed from two partial flaps 65 and 66, which are connected via a center hinge 30 hinged together. In addition, the partial flap 66 is pivotally connected to the furniture body 64 of the furniture 27. The partial flap 65 is moved via an actuating unit 50, which is likewise arranged on the furniture body 64 and comprises a force accumulator. For ejecting the folding flap 22 from the coplanar closed position into a folded open position, an ejection device 1 can be arranged between the partial flaps 65 and 66. Alternatively, of course, the ejection devices 101 or 201 (see the following figures) can be used.

The ejection device according to the invention can also be used in other furniture, such as drawers.

A third preferred embodiment of the ejection device 201 is shown in FIGS. 15a to 28f. From the basic principle, this ejection device 201 works like the ejection device 1. Nevertheless, there are a number of differences, which relate in particular to the switching element 207 and related components. The ejection device 201 is disposed between the door leaves 19 and 20 of a folding-sliding door 2. In this case, the ejection device 201 is connected, on the one hand, to the door leaf 19 via a fitting part 240 and, on the other hand, via a fitting part 224 to the door leaf 20. A reverse arrangement on the door leaves 19 and 20 is possible.

In the figure 15a, the closed position of the folding-sliding door 2 is shown. In this position, the ejection device 201 contacts the end face 29 of the furniture body 15 (see FIGS. 1 a to 1 d) via an unlocking device 210. As can be seen in particular from FIG. 15 d, the unlocking device 210 comprises a contact lever 283, which has two pivotally mounted fastening levers 284 and 279 is connected to the ejection device 201. The attachment levers 284 and 279 are at an acute angle to each other. The attachment levers 284 and 279 pivot on the ejector 201 about pivot points 285 and 278, respectively. The contact lever 283 is connected via the pivot points 282 and 281 with the fastening levers 284 and 279. The distance of the pivot points 281 and 282 is smaller than the distance of the pivot points 278 and 285. Between the fastening levers 284 and 279, a spring 280 is tensioned. This spring 280 ensures that the fastening levers 284 and 279 occupy the smallest possible distance from one another, as a result of which the contact lever 283 is pushed away from the ejection device 201 and, in the closed position, abuts against the end face 29 of the furniture body 15. The point of contact of the contact lever 283 with the end face 29 of the furniture body 15 is provided with the reference numeral 251. The end of the contact lever 283, on which the contact point 251 is disposed, faces the end of the contact lever 283 at which the fulcrums 282 and 281 are provided. The unlocking device 210 has a further lever 21 1, which is on the one hand connected to the fastening lever 284 via a pivot point 286 and on the other hand has a free end of the lever. This free end of the lever is hook-shaped and has a U-shaped contact point 212. The ejection device 201 further comprises a switching element 207, which is rotatably mounted about a switching axis 276. The switching element 207 is rotationally symmetrical. It also comprises hook-shaped latching projections 277, which can interact with the lever 211 of the unlocking device 110. This situation is shown in Figure 15d: the lever 21 1 contacts the switching element 207 via the contact point 212. This is the activation position of the switching element 207. The lever 211 provides a Coupling device for coupling the unlocking device 210 with the switching element

207 dar.

The unlocking device 205 is formed in this embodiment of the ejection device 201 as a pivotally mounted lever 216 which is pivotally mounted about the rotation axis 257 on the ejection device 201. The locking device 205 comprises a latching projection 244. This can engage in a corresponding latching projection 287, as shown in Figure 15e. The latching projection 287 is on a component

208 formed, which is rotatably mounted about a rotation axis 242 on the ejection device 201. On the component 208, a rolling body 217 is also mounted about the rotation axis 241. This rolling element 217 can thus move on a circular path about the pivot points 242.

The rolling body 217 is acted upon by a slide 236 from a discharge energy storage 204. Furthermore, the rolling element 217 contacts a setting contour 218, which can be seen particularly well in FIG. 15f. The control contour 218 has a minimum 260 and two adjacent maxima 289 and 288. The adjusting contour 218 is rotatably mounted about an axis of rotation 247 on the ejection device 201. Rotationally fixed to the control contour 218, an ejection element 203 is connected in the form of a fork-shaped lever. If the setting contour 218 moves about the axis of rotation 247, then the ejection element 203 also moves forcibly, and vice versa.

The control contour 218 and the rolling body 217 together form a transmission device, which is arranged between the ejection energy storage 204 and the ejection element 203.

The locking device 205 is connected to the switching element 207 via a mechanism in combination, which is shown in particular in Figure 15c. On the switching axis 276 of the switching element 207, a control contour 215 is arranged rotationally fixed. This is also rotationally symmetrical. On the control contour 215, a push button 214 can be supported, which is connected via two pivoting levers 271 and 274 with the ejection device 201. The pivot lever 271 is mounted on the one hand about a rotational axis 272 rotatably mounted on the ejection device 201. On the other hand, the pivot lever 271 is connected via a pivot 270 to the push button 214. Accordingly, the pivot lever 274 is mounted on the one hand about a rotational axis 273 rotatably mounted on the ejection device 201. On the other hand, the pivot lever 274 is connected via a pivot point 275 to the button 214. By a spring 213, which is arranged between the ejection device 201 and the push button 214, the push button 214 is pressed in the direction of the control contour 215. The button 214 is also movably coupled to the locking device 205. If a user now exerts a force on the folding sliding door 2 in the closing direction 6, so that the folding sliding door 2 moves from the closed position to an overpressure position arranged in the closing direction 6 behind the closed position, the contact lever 283 of the unlocking device 210 moves in the direction of the ejection device 201 (see Figures 16a to 16f, in particular Figure 16d). As a result, the coupling lever 21 1 is pulled in the opposite direction, ie in the direction of the end face 29 of the furniture body 15 in a further consequence. Characterized in that the lever 21 1 engages in the switching element 207, the switching element 207 is rotated about the axis of rotation 276.

This rotational movement of the switching element 207 simultaneously causes a rotation of the control contour 215 (see FIG. 16 c), since the switching element 207 and the control contour 215 are arranged on a common axis of rotation 276. In the initial position shown in Figure 15c, the tip of the probe 214 was located in a first detent recess 291. If the control contour 215 is now rotated, the control contour 215 displaces the button 214 from the detent recess 291 along a flank 248th Thus, the button 214 of the Control contour 215 moved away.

The movement of the probe 214 subsequently causes a pivoting of the lever 216 of the locking device 205 about the axis of rotation 257, whereby the lever 216 moves away from the coupling member 208 and the lock is released.

FIGS. 17a to 17f show the maximum overpressure position. The lever 216 of the locking device 205 has completely released the component 208. At the same time, the tip of the probe 214, which contacts the control contour 215, has moved over the flank 248 into a second detent recess 290. In this detent recess 290 of the button 214 is kept stable. As a result, the lever 216 of the locking device 205 is also held stably in the unlocked position.

If the user now lets go of the folding / sliding door 2, the component 208 can be pivoted about the axis of rotation 242 under the influence of the force stored in the ejection energy store 204 (compare FIGS. 18a to 18f). The contact lever 283 and the coupled therewith coupling lever 211 of the unlocking device 210 moves under the influence of Spring 280 back to its original position. As can be seen from a comparison of Figures 15d and 18d, the switching element 207 but now assumes a position in which the coupling lever 21 1 does not engage in the switching element 207. In other words, the coupling device 211 is formed contactless to the switching element 207 at the contact point 212. The switching element 207 is in a deactivation position in which the locking device 205 is unlockable.

As can be seen from the further sequence of FIGS. 19a to 19f, 20a to 20f and 21a to 21f, the released force, which is stored in the ejection energy store 204, moves the rolling body 217 along the control contour 218 in the direction of the minimum 260. As a result, the setting contour 218 is pivoted about the axis of rotation 247. This pivoting movement continues on the ejection element 203, which subsequently pivots the door leaf 20 relative to the door leaf 19. As a result, the movable furniture part 2 is transferred from the closed position to the open position.

As a comparison of Figures 19e, 20e and 21 e shows the component 208 occurs during the rotational movement about the rotation axis 242 via a projection 292 with another rotary member 209, which is also arranged on the rotation axis 276 in contact. The rotary member 209 is also rotationally symmetrical and has three wings 258 which can come into contact with the projection 292 of the member 208. The rotary member 209 with the wings 258 represents a stop contour, which can be taken from the component 208. Thus, the component 208 can also be understood as a driver. The rotational movement of the rotary member 209 continues in a rotational movement of the switching element 207 and the control contour 215. Overall, the driver 208 and the stop contour 209 thus form a coupling device, via which the switching element 207 is coupled to the ejection element 203.

Due to the rotational movement of the control contour 215, the button 214 moves out of the Rustmulde 290 out again. Although the switching element 207 has been further moved by the rotation of the rotary member 209, not yet so far that the switching element 207 would again be in an activation position. Rather, the switching element 207 is in a further deactivation position.

FIGS. 21 a to 21 f show the position of the ejection device 201 in which the ejection energy accumulator 204 is completely discharged. The rolling element 217 is located in the minimum 260 of the control contour 218. Starting from this position, a user now usually exerts a force 61 to further fold the folding-sliding door 2 together. Figures 22a to 22f, 23a to 23f, 24a to 24f and 25a to 25f show several intermediate positions in this folding movement of the folding-sliding door 2.

The control contour 218 is now actively moved by the user about the axis of rotation 247. The rolling element 217 is thereby forced out of the minimum 260 and moved back in the direction of the original position. As a result, the ejection force memory 204 is reloaded.

At the same time, the component 208 is pivoted back about the rotation axis 242. Since the button 214 is no longer in the detent recess 290, the spring 213 again has the opportunity to move the button 214 and thus the lever 216 of the locking device 205 in the direction of the starting position. The button 214 also simultaneously rotates the control contour 215 and thus the switching element 207 until the tip of the probe 214 is again arranged in the original detent recess 291 of the control contour 215, and the switching element 207 is in the activation position (see FIGS. 25c and 25d) ). Now the locking device 205 could be unlocked again.

Usually, the folding-sliding door 2, starting from the position shown in Figures 25a to 25f further folded together and possibly stowed in a cavity 26 in the furniture body 15 (see Figures 1 a to 1 d). Subsequently, the folding-sliding door 2 is again transferred to the original closed position. In this case, nothing changes at the position of the components of the locking device 205.

Figures 26a to 26f, 27a to 27f and 28a to 28f show a different motion scenario. In fact, the user decides during or immediately after the ejection of the movable furniture part 2 to actively move the furniture part 2 back to its original closed position ("emergency closing") As a result, the roller body 217 is urged back to the original position at the setting contour 218, specifically along the section of the control contour 218 on which the rolling element 217 has moved until the movement is reversed. The component 208 is pivoted back about the rotation axis 242 again. The button 214 rotates under the influence of the spring 213, the control contour 215 and thus the switching element 207 on. Upon reaching the closed position (see Figures 27a to 27f), the switching element 207 but is still in a deactivation position in which the coupling lever 21 1 does not yet engage in the switching element 207.

In the further movement in the direction of the overpressure position, the switching element 207 is rotated even further, so that it is then in the activation position. At the same time, however, the coupling lever 21 1 of the unlocking device 210 is pressed in the opposite direction, so that the coupling lever 21 1 can not initially engage in the switching element 207. By the movement of the furniture part 2 from the closed position into the overpressure position during emergency closing, therefore, no immediate unlocking of the locking device 205 takes place. Only when the user lets go of the furniture part 2, the unlocking device 210 moves back to the original position (see Figure 15d) back, and the coupling lever 211 can engage in the switching element 207.

From FIGS. 29a and 29b it can be seen that some components of the ejection device 201 can be made in two parts in order to increase the stability. This example in the control contour 218, the component 208, the lever 216 of the locking device 205, the button 214, the fastening lever 279 and 284 and the control contour 215 of the case.

Furthermore, it can be seen that the ejection element 203 is connected to the fitting part 224 at a first end with the control contour 218 and with second ends 223 on which rolling bodies are arranged. The rolling elements are slidably mounted in grooves 254.

Finally, it should be noted that in this embodiment, a stabilizing device 238 is provided to prevent buckling of the ejection force memory 204. In FIGS. 30a and 30b, it can be clearly seen that the control contour 215, the switching element 207 and the rotary part 209 are arranged rotationally fixed on a common indexing axis 276. This means that the rotation of one of these components causes the rotation of the other components. Also clearly visible are the latching recesses 290 and 291 and the flanks 248 of the control contour 215, the latching projections 277 of the switching element 207 and the wings 258 of the rotary part 209.
