Further advantages and details of the invention will become apparent from the FIGS. 1 to 13 , The sequence of the FIGS. 1 to 12 , each comprising three sub-figures a, b and c, to illustrate the operation of the ejection device according to a particularly preferred embodiment of the invention. The subfigures a and b each show a view of the ejection device viewed from the interior of the furniture, wherein in the subfigures b a number of components of the ejection device have been omitted to release the view of the locking device. In the subfigures c a complete furniture with a folding-sliding door is shown in each case. The FIG. 13 shows an exploded view of the ejector.

On the basis of this exploded view, the basic structure of the ejection device according to the particularly preferred embodiment of the invention can be understood:
The ejection device (provided in the other figures with the reference numeral 1) comprises a base member 21 which can be fixedly arranged on a furniture body of a piece of furniture.

The base member 21 has a plurality of guideways 53, 54, and 59. In this case, the guide track 53 for guiding a arranged on a driver 16 bolt 47, the guide rail 54 for guiding a arranged on a locking element 9 pin 62 and the guide track 59 for guiding a carriage 23, on which the locking element 9 is pivotally mounted, is provided. It should also be noted that the guideway 54 comprises a heart curve-shaped locking contour 8, on which the locking element 9 and the pin 62 of this locking element can be supported.

The base member 21 may be provided with a cover 50, which cover serves to support the carriage 23 and the driver 16. The guideways 48 and 51 provided in the cover 50 ensure that the driver 16 and the carriage 23 are substantially linearly displaceable relative to the base element 21.

The ejection device further comprises a force accumulator 7, in the form of a tension spring, which has a first end 60 and a second end 61. The first end 60 is fixedly connected via an intermediate element 20 with the base member 21. The second end 61 of the spring is connected to a relative to the base member 21 movable spring retainer 22. This movable spring position is formed on an intermediate lever 24, which is pivotally mounted on the carriage 23 on the one hand (for this purpose corresponding attachment points 46 and 58 are provided on the intermediate lever 24 and carriage 23). On the other hand, the intermediate lever 24 is pivotally connected to an ejection element 5 via attachment points 45 and 57, the attachment point 45 being formed on the intermediate lever 24 and the attachment point 57 on the ejection element 5.

The ejection element 5 has a lever 17, with a free end of the lever 18 to which a rotatably mounted rolling element 19 is arranged for contacting the folding-sliding door or an element connected thereto at least during buckling thereof. The lever 17 is pivotally connected to the base member 21 (this attachment points 43 and 52 are provided on the lever 17 and the base member 21).

Furthermore, the ejection device also comprises a charging device for charging the energy accumulator 7. Essential components of this charging device are a control contour 15, which is pivotally connected on the one hand to the ejection element 5 via a force transmission element 25. For this purpose, the lever 17 of the ejection element 5 has an attachment point 42, the Control contour 15, an attachment point 41 and the force transmission element 25 attachment points 39 and 40 on. On the other hand, the control contour 15 is pivotally mounted on the base member 21. For this purpose, an attachment point 44 are provided on the control contour 15 and an attachment point 56 is provided on the base element 21. Fasteners that secure the pivotal mounting can pass through an opening 49 in the cover 50. An essential part of the charging device is furthermore a control element 14, which is designed as a rolling element and is arranged on the driver 16. The control element 14 is displaceably mounted in the guide track 48 of the cover 50.

With respect to the driver 16 it should also be noted that this is the movement coupling of the folding-sliding door with the loading device at least when loading the energy storage device 7, and a recess 55 for temporarily receiving a portion of a carriage 29, with the folding-sliding door is connected (see for example FIG. 1a ).

With reference to the FIGS. 1 to 12 Let us now explain in detail the operation of the ejection device 1:
The FIGS. 1a to 1c refer to the closed position of a movably mounted on a furniture cover 13 2 in the form of a folding-sliding door, which comprises two hingedly interconnected door leaves 3 and 4. In this closed position, the two door leaves 3 and 4 are arranged in a common closing plane. Furthermore, the folding-sliding door covers the interior of the furniture 13 in this closed position.

The furniture 13 comprises a furniture body, formed from a cover plate 27, a bottom plate 35, a rear wall 36 and a plurality of side walls 30, 31 and 33, which are arranged substantially parallel to each other and spaced from each other (see also the other subfigures c of FIGS. 1 to 12 ). The furniture 13 further comprises a shaft-shaped cavity 26 for Receiving the folding-sliding door 2, wherein this cavity is defined by boundary surfaces in the form of two side walls 31 and 33 and in the form of a portion 32 of the rear wall 36 of the furniture thirteenth

FIG. 1a shows the ejection device 1 for the folding-sliding door in this closed position of the folding-sliding door and FIG. 1b a part of this ejection device, namely the locking device for releasably locking the ejection element in the form of the heart-shaped locking contour 8 and the locking element 9, which is supported on the locking contour 8. More specifically, the locking element 9 is a pivoting lever, at the free end of a pin 62 is arranged, which is arranged in the closed position of the folding-sliding door in the trough of the heart cam 8. The locking element 9 is pivotally mounted on the carriage 23, which in turn is connected via the intermediate lever 24, which comprises the movable spring holder 22, with the movably mounted end 61 of the spring 7 in connection. In the closed position of the folding-sliding door 2 of the energy storage 7 and the spring is loaded. This means that the locking device ensures in this state that the stored energy in the energy storage can not be released.

The unlocking of the locking device takes place by applying pressure to the folding-sliding door 2 in the area 10 in which the two door leaves 3 and 4 are hinged together. In this case, the folding-sliding door 2 is moved from the closed position to an overpressure position located behind the closed position. This overpressure position is the FIGS. 2a to 2c shown.

Comparing the Figures 1b and 2 B so it is obvious that the transition from the closed position in the overpressure of the control pin 62 is moved from the trough of the heart-shaped locking contour 8 also in such a way that when releasing the folding-sliding door 2 in the energy storage. 7 stored energy can be released. In this case, the tension spring 7 contracts, which means that the movably mounted end 61 of the spring moves towards the stationarily arranged end 60 of the spring. In this case, the movable spring holder 22 and thus the entire intermediate lever 24 is forcibly moved along, wherein the positive guidance via the carriage 23 and the guideways 54, 59 and 51 takes place.

The movement of the intermediate lever 24 is converted into a pivoting movement of the ejection element 5, more precisely, the lever 17, as a comparison of FIGS. 2a and 3a shows, wherein the FIGS. 3a to 3c refer to the position of the ejector 1, in which the energy storage device 7 is substantially completely discharged.

About a free end of the lever 18 of the lever 17 rotatably mounted rolling elements 19, the pivotal movement of the lever 17 is converted into a Aufknickbewegung the folding-sliding door 2. Here, the rolling element 19 is supported on a arranged on the folding-sliding door drain contour 28.

Like a comparison of Figures 2c and 3c shows the folding-sliding door 2 was by the ejector 1 in the course of the Aufknickbewegung from the closed position in which the two door leaves 3 and 4 are arranged in a common closing plane, in an open position in which the two door leaves 3 and 4 a Angle 6 not equal to 180 ° to each other conveyed. The Aufknickbewegung thus took place substantially in a direction 11 perpendicular to the closing plane.

From the FIG. 3b It is apparent that the control pin 62 arranged on the locking element 9 has reached the end of the guide track 54 opposite the heart-shaped locking contour 8 when the force accumulator 7 is discharged.

Finally, it should be noted that the ejection device 1 has moved the folding-sliding door 2 when buckling in a direction 12 parallel to the closing plane, more precisely in the direction of the shaft-shaped cavity 26. In this case, the carriage 29, on which the door leaf 3 is pivotally mounted, a distance along a arranged on the cover plate 27 of the furniture 13 guiding device 34 moves along. This guide device is designed such that the carriage 29 can be moved as smoothly as possible.

Due to its inertia, the folding-sliding door 2 moves after the caused by the ejection device 1 Aufknickbewegung even further, even if the energy storage 7 is already discharged. In this case, the door leaf 3 of the folding-sliding door 2 lifts off from the rolling element 19. At the same time, the angle 6, which the two door leaves 3 and 4 enclose relative to one another, is further reduced. When the energy is dissipated, the folding-sliding door 2 comes to a standstill. In doing so, she occupies a position approximately in the FIGS. 4a to 4c is shown.

Apart from the fact that the rolling elements 19 no longer contacts the drain contour 28, has, as a comparison of FIGS. 3a and 4a shows, the carriage 29 is moved even further in the direction 12 parallel to the closing plane or even further in the direction of the shaft-shaped cavity 26.

In the area of the carriage 29, in which the carriage 29 is coupled to the folding-sliding door 2, the carriage 29 is coupled to the driver 16. For the purpose of this temporary coupling, the driver has the recess 55. As a result of the movement coupling, the driver 16 has also been forcibly guided in the direction 12 parallel to the closing plane or in the direction of the shaft-shaped cavity 26, the positive guidance in this case being transmitted via the guide tracks 53 and 48 (cf. FIG. 13 ) he follows. In the position according to FIG. 4a has the driver 16 here reaches a position in which the arranged on the driver control element 14 in the form of the rolling element, the control contour 15 of the loading device for loading the force accumulator 7 contacted for the first time.

For further opening of the folding-sliding door 2 now engages a user, preferably by the free edge of the door leaf 3 engages behind and a force in the direction of the shaft-shaped cavity 26, ie in the direction 12 parallel to the closing plane of the folding-sliding door 2 exercises. Here, the folding-sliding door 2 via the in the Figures 5 . 6 and 7 shown intermediate positions in a folded position (see FIG. 8 ).

Part of the energy transmitted by the user to the folding-sliding door 2 is used to charge the energy storage device 7, in the course of a continuous opening of the folding-sliding door 2 immediately following the buckling.

In detail, the loading of the energy accumulator 7 takes place in that the driver 16 is moved by the movement coupling with the carriage 29 in the direction 12 parallel to the closing plane or in the direction of the shaft-shaped cavity 26. This movement is implemented via the arranged on the driver 16 rolling elements 14 in a pivoting movement of the control contour 15, which in turn via the force transmission element 25, the lever 17 of the ejection element 5 and thus the intermediate lever 24 back to the original closed position FIG. 1 moved back. In this case, the spring 7 is pulled apart, that is transmitted energy to the energy storage 7.

The control contour 15 is designed such that the user initially experiences a low resistance and then increases. This is advantageous because the user usually has to accelerate the folding-sliding door 2 only from a standstill out.

The FIGS. 5a to 5c show an intermediate position during the loading of the energy accumulator. 7

The FIGS. 6a to 6c show the state of the ejection device 1, in which the energy storage 7 is fully charged again. In this state, the locking pin 9 arranged on the control pin 62 is again in the trough of the heart-shaped locking contour 8, that is, that the ejection element 5 is locked against being acted upon by the charged energy storage device 7 by means of the locking device again.

When the charging process is completed, the driver 16 pivots. For this purpose, a bent section is provided in the guide track 53. By pivoting the movement coupling with the folding-sliding door 2 and the carriage 29 is repealed. Now, the folding-sliding door 2 over in the FIGS. 7a to 7c shown intermediate position unhindered in the folded position according to FIG. 8c be moved on. The ejector 1 remains in the position according to the FIGS. 6a to 6c ,

Starting from this folded position, the user now has the opportunity to stow the folding-sliding door 2 in the shaft-shaped cavity 26. For this he exerts a force on the folding-sliding door 2 in the folded position, that is, on the door package in the direction of the rear wall 36 of the furniture 13. The door leaf 4 of the folding-sliding door 2 is preferably arranged via hinges 38 on a support element 37, which in turn is slidably mounted in the longitudinal direction of the shaft 26 via guide elements 63 which are arranged on the side wall 31.

In order to support the movement of the folding-sliding door 2 from a, preferably completely, recessed position in the cavity 26 to the position outside the cavity, a drive device may be provided, which, after initialization by a user, automatically moves the folding-sliding door 2 out of the cavity 26.

Furthermore, a spreading device for spreading open the door leaf 3 and 4 from the folded position in the spread position may be provided, which immediately after reaching the position outside of the cavity 26 according to the FIG. 8c becomes effective, so that the folding-sliding door 2 is not only automatically moved out of the cavity 26, but then also in a slightly spread position, so that a user has a better attack opportunity to the folding-sliding door 2 again in its closed position, in which the two door leaves 3 and 4 are arranged in the common closing plane to convey.

The transfer to the closed position, starting from the full open position according to the FIGS. 8a to 8c is in the FIGS. 9 to 12 shown, wherein the FIG. 12 again showing the closed position, which is also in the FIG. 1 is shown.

First, the folding-sliding door 2 and the carriage 29 in the direction 12 parallel to the closing plane, but this time away from the cavity 26 and that until the carriage 29, the driver 16 contacted (see FIG. 10 ). Until then, nothing has changed at the position of the ejector 1.

Now, as a comparison of Figures 10 and 11 shows, the driver 16 is taken from the carriage 29 and that until he has returned to its original position. At the position of the remaining parts of the ejection device 1 changes nothing.
