  • the invention relates to an ejection device for a movable furniture part, with at least one ejection element for ejecting the movable furniture part from a closed position into an open position, at least one ejection force accumulator for applying force to the at least one ejection element when the movable furniture part is ejected from the closed position into 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 pushing the movable furniture part into a pushing-over position located behind the closed position in the closing direction.
  • the invention further relates to a piece of furniture with a furniture body, at least one furniture part that can be moved relative to the furniture body, and at least one such ejection device.
  • An ejection device is for example from WO 2013/106873 A1 known.
  • a fundamental problem with this ejection device is that when the movable furniture part moves from the open position to the closed position, you want to prevent the locking device from being unintentionally unlocked again and the movable furniture part being ejected again from the ejection device from the closed position to the open position.
  • the object of the present invention is therefore to specify an ejection device according to the preamble of claim 1 with an improved push-through protection compared to the prior art, in which in particular the disadvantages described are avoided.
  • a further object of the invention consists in specifying a piece of furniture with such an ejection device according to the invention.
  • At least one switching element which is operatively connected to the at least one locking device is provided, which has at least one activation position in which the at least one locking device can be unlocked, and at least one deactivation position in which the at least one locking device cannot be unlocked is, having, wherein the at least one switching element is movable when the movable furniture part is ejected from the closed position into the open position and/or by unlocking the at least one locking device into the at least one deactivation position.
  • the at least one switching element can be moved into the at least one deactivation position when the movable furniture part is ejected and/or by unlocking the at least one locking device, and the locking device cannot therefore be unlocked, ensures that the push-through protection, i.e. unintentional unlocking of the locking device , is activated by the opening movement of the movable furniture part and no longer, as is provided according to the prior art, by the closing movement of the movable furniture part. So no part of the closing energy has to be diverted to activate the push-through protection.
  • the solution according to the invention allows a movement of the movable furniture part from the closed position to the overpressure position rather.
  • the at least one switching element in the at least one deactivation position at least at the start of the movement of the movable furniture part into the override position—ensures that the at least one locking device cannot be unlocked during this movement. Mechanical damage to the push-through protection is impossible.
  • 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 implemented, for example, by providing a coupling device via which the at least one switching element can be coupled directly or indirectly to the at least one ejection element , preferably wherein the coupling device comprises a driver and a stop contour, particularly preferably wherein the stop contour comprises a slot in which the driver is movably mounted.
  • the coupling device comprises a driver and a stop contour, particularly preferably wherein the stop contour comprises a slot in which the driver is movably mounted.

  • At least one resetting device is provided, via which the at least one switch element is activated after the movable furniture part has been ejected from the closed position into the open position or the at least one locking device has been unlocked from the at least one deactivation position into the at least one Activation position is movable.
  • the at least one resetting device moves after the ejection or unlocking of the at least one switching element from the deactivated position to the activated position is not decisive. 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 also does not have to be effected by a restoring 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.
  • the at least one resetting device it has proven to be advantageous for the at least one resetting device to include a timer, via which the at least one switching element is time-delayed after the moveable furniture part has been ejected from the closed position into the open position or after the at least one

  • "Relative position of the movable furniture part" in relation to the furniture body can mean, for example, in the case of a drawer as the movable furniture part, a specific distance between the front panel of this drawer and the end face of the furniture part.
  • the "relative position of the movable furniture part" in relation to the furniture body can also mean a specific angular position of the two Be meant door leaf relative to each other.
  • a further advantageous embodiment of the invention is that the at least one locking device comprises at least one lever arm which is pivotably mounted and/or can be locked in a positive and/or non-positive manner.
  • a positive connection can be realized, for example, by a locking projection that engages behind a bolt or the like.

  • 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 by the force accumulator 13 on one side and by the damper 14 on the other side.
  • the unlocking device 10 unlocks the locking device 5 by exerting force on the connecting axis 48.
  • the locking projection 44 gains enough play relative to the locking pin 43 to eliminate the positive and non-positive connection.
  • a user lets go of the ejection device 1 or the movable furniture part 2 connected to it (cf Figures 6a to 6c ).
  • the force stored in the ejection force accumulator 4 can escape, as a result of which the slide 36 executes a linear movement.
  • the switching element 7 is also moved via the driver 8, which strikes a first stop surface 58 of the elongated hole 9 after a short time.
  • the switching element 7 is pulled away from the unlocking device 10 and the contact point 12 of the coupling device 11 (compare in particular Figure 6c ).
  • the energy accumulator 13 of the timer which acts on the switching element 7, is compressed and the damper 14 relaxes.
  • the slide 36 subsequently exerts a force on the setting contours 18 and thus on the ejection elements 3 via the rolling bodies 17 .
  • the positioning contours 18 and the ejection elements 3 are thus pivoted about the axis of rotation 47 .
  • the fitting parts 24 and the door leaf 19 and 20 connected thereto 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, into a position in which the Door leaves 19 and 20 enclose an angle other than 180° to one another (see in particular Figure 6a ).
  • the ejection movement is ended by the fact that the ejection force accumulator 4 is completely discharged.
  • the position that the ejector 1 occupies at this time is in the Figures 7a to 7d shown.
  • the rolling element 17 is in this position in a minimum 60 which is encompassed by the setting contour 18 .
  • the user now wants to open the movable furniture part 2 further. To do this, he exerts a force 61 on the movable furniture part 2 . If the movable furniture part 2 is a folding/sliding door, the exertion of force moves the folding/sliding door in the direction of a position in which the folding/sliding door is folded together.
  • the ejection elements 3 or the actuating contours 18 connected thereto are pivoted further about the axis of rotation 47 . Since the actuating contours 18 rest against the rolling elements 17 of the slide 36, the slide 36 is moved back in the direction of the initial position which the slide 36 has assumed in the locked state. As a result, the ejection force accumulator 4 is subsequently reloaded.
  • the reset device becomes effective. This means that the energy store 13 stored power is released again and the switching element 7 is moved back to the original activation position against the action of the damper 14 .
  • the push-through protection which was activated when the movable furniture part 2 was ejected from the closed position into the open position, is thus deactivated again in the course of a loading movement of the ejection device 1 .
  • the Figures 8a and 8b show the folded state of the ejection device 1 or the movable furniture part 2.
  • the furniture part 2 can now be moved into a cavity 26 in the furniture body 15.
  • the ejection device 1 assumes a quasi-locked state. This condition comes about because the ejection device 1 has to be stowed away in as space-saving a manner 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 . If you now unfold the folding sliding door 2 again, the locking device 5 is immediately locked again. A movement of the slide 36 is blocked by the setting contours 18 .
  • FIG 9 shows the ejection device 1 in an intermediate position during transfer into the closed position, starting from the folded position according to FIG Figure 8b . It can be seen that the locking device 5 is locked.
  • a force 62 is exerted on the ejection device 1 or the door leaves connected to it 19 and 20 exercised.
  • this force 62 is provided by a drive device 30 which is designed to automatically move the movable furniture part 2 into the closed position.
  • the drive device 30 can be, for example, the central hinges which connect the door leaves 19 and 20 to one another. However, a separate drive device can also be provided as an alternative or in addition to this.
  • a drive device 49 can also be provided, which transfers the door assembly from the cavity 26 to a position outside of the cavity 26 .
  • the drive device 30 can also be divided into two parts, to the effect that a first part causes the door assembly to fold open from the folded position into an intermediate position and a second part causes a transfer from the intermediate position into the final closed position. Since the force provided by the drive device 30 can be set precisely, the movable furniture part 2 will always move into the closed position at the same speed. A push-through protection is not necessary in this case, since the force can be measured in such a way that the movable furniture part, starting from the closed position, is no longer moved into the push-over position.
  • the unlocking device 10 is therefore designed without contact with the switching element 7 . If the user doses his force 63 too high, the movable furniture part 2 is moved further via the closed position into the overpressing position (cf figure 11 ). However, because the unlocking device 10 cannot be supported on the switching element 7, the locking device 5 remains locked. This means that the locking device 5 cannot be unlocked. Only after a certain time is the switching element 7 moved back into the activation position. However, the user then generally no longer exerts any force on the ejection device 1 . The ejection device 1 remains locked.
  • FIGs 13a to 13c show a second preferred embodiment of the ejection device 101, specifically in the locked closed position ( Figure 13a ), in the override position ( Figure 13b ) and in a position immediately after unlocking ( Figure 13c ).
  • the unlocking device 110 is connected to the first door leaf 19 and the second door leaf 20, or the two fitting parts 40 and 24, when the locking device 5 is unlocked, so that the unlocking device 110 causes a relative change in the angle of the two Door leaves 19 and 20 to each other when unlocking the locking device 5 can detect.
  • This can be, for example, a rope 55 which, in the closed position, is stretched tautly between an end 69 of the unlocking device 110 and a connection point 56 on the fitting part 24 . If the ejector device 101 is now moved from the closed position into the push-over position, the unlocking device 110 is moved in the direction of the locking device 5 .
  • the locking device 5 Since the unlocking device 110 is simultaneously supported on the switching element 7 described in detail in connection with the first exemplary embodiment, the locking device 5 is unlocked. It is therefore no longer necessary to contact the furniture body 15 in order to unlock it. This has the great advantage that the ejection device 101 can be arranged at any point on the movable furniture part 2 .
  • the Figures 14a and 14b show a piece of furniture 27 in the form of a wall unit 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 to one another in an articulated manner via a central hinge 30 .
  • the partial flap 66 is connected in an articulated manner to the furniture body 64 of the piece of furniture 27 .
  • the partial flap 65 is moved via an actuating unit 50, which is also arranged on the furniture body 64 and includes an energy accumulator.
  • An ejection device 1 can be arranged between the partial flaps 65 and 66 in order to eject the folding flap 22 from the coplanar closed position into a folded open position.
  • the ejection devices 101 or 201 can also be used.
  • the ejection device according to the invention can also be used with other furniture, for example drawers.
  • FIG. 15a to 28f A third preferred embodiment of the ejection device 201 is shown. In terms of the basic principle, this ejection device 201 functions like the ejection device 1. Nevertheless, there are a number of differences which relate in particular to the switching element 207 and components connected thereto.
  • the ejection device 201 is arranged between the door leaves 19 and 20 of a folding and sliding door 2 .
  • 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 to the door leaf 20 via a fitting part 224 .
  • a reverse arrangement on the door leaves 19 and 20 is also possible.
  • the closed position of the folding sliding door 2 is shown.
  • the ejection device 201 contacts the end face 29 of the furniture body 15 (cf Figures 1a to 1d ) via an unlocking device 210.
  • the unlocking device 210 comprises a contact lever 283, which is connected to the ejection device 201 via two pivotably mounted fastening levers 284 and 279.
  • the fastening levers 284 and 279 form an acute angle with one another.
  • the mounting levers 284 and 279 are pivotable on the ejector 201 about pivot points 285 and 278, respectively.
  • the contact lever 283 is connected to the attachment levers 284 and 279 via the pivot points 282 and 281 .
  • the distance between the pivot points 281 and 282 is smaller than the distance between the pivot points 278 and 285.
  • a spring 280 is tensioned. This spring 280 ensures that the fastening levers 284 and 279 are as small as possible from one another, as a result of which the contact lever 283 is pushed away from the ejection device 201 and rests against the end face 29 of the furniture body 15 in the closed position.
  • the point of contact of the contact lever 283 with the end face 29 of the furniture body 15 is provided with the reference number 251 .
  • the end of the contact lever 283 on which the contact point 251 is located is opposite to the end of the contact lever 283 on which the fulcrums 282 and 281 are provided.
  • the unlocking device 210 has a further lever 211 which is connected on the one hand 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 also includes a switching element 207 which is mounted so as to be rotatable about a switching axis 276 .
  • the switching element 207 is rotationally symmetrical. It also includes hook-shaped latching projections 277 which can interact with the lever 211 of the unlocking device 110 .
  • This situation is in the Figure 15d shown: the lever 211 contacts the switching element 207 via the contact point 212. This is the activation position of the switching element 207.
  • the lever 211 represents a coupling device for coupling the unlocking device 210 to the switching element 207.
  • the unlocking device 205 is designed as a pivotably mounted lever 216 which is mounted on the ejection device 201 such that it can pivot about the axis of rotation 257 .
  • the locking device 205 includes a locking projection 244. This can engage in a corresponding locking projection 287, as shown in FIG Figure 15e is shown.
  • the latching projection 287 is formed on a component 208 which is mounted on the ejection device 201 so as to be rotatable about an axis of rotation 242 .
  • a rolling element 217 is also mounted on the component 208 about the axis of rotation 241 . This rolling element 217 can therefore move on a circular path around the pivot point 242 .
  • the rolling body 217 is acted upon by an ejection force accumulator 204 via a slide 236 . Furthermore, the rolling element 217 contacts an actuating contour 218, which is particularly good in the Figure 15f you can see.
  • the setting contour 218 has a minimum 260 and two neighboring maxima 289 and 288 on.
  • the setting contour 218 is mounted on the ejector device 201 such that it can rotate about an axis of rotation 247 .
  • An ejection element 203 in the form of a fork-shaped lever is connected in a rotationally fixed manner to the setting contour 218 . If the setting contour 218 moves about the axis of rotation 247, then the ejection element 203 is forced to move as well, and vice versa.
  • the adjusting contour 218 and the rolling element 217 together form a transmission device which is arranged between the ejection force accumulator 204 and the ejection element 203 .
  • the locking device 205 is connected to the switching element 207 via a mechanism which, in particular, in the Figure 15c is shown.
  • a control contour 215 is arranged in a rotationally fixed manner. This is also rotationally symmetrical.
  • a button 214 can be supported on the control contour 215 and is connected to the ejection device 201 via two pivoted levers 271 and 274 .
  • the pivoted lever 271 is mounted on the ejection device 201 so as to be rotatable about an axis of rotation 272 .
  • the pivoted lever 271 is connected to the button 214 via a pivot point 270 .
  • the pivoting lever 274 is mounted on the ejection device 201 so as to be rotatable on the one hand about an axis of rotation 273 .
  • the pivoted lever 274 is connected to the button 214 via a pivot point 275 .
  • a spring 213, which is arranged between the ejector 201 and the button 214 the button 214 in the direction of Control contour 215 pressed.
  • the button 214 is also coupled in terms of movement to the locking device 205 .
  • the movement of the button 214 subsequently causes a pivoting of the lever 216 of the locking device 205 about the axis of rotation 257, whereby the lever 216 of the Coupling member 208 is moved away and the lock is released.
  • the component 208 can be pivoted about the axis of rotation 242 under the influence of the force stored in the ejection force accumulator 204 (cf Figures 18a to 18f ).
  • the contact lever 283 and the coupling lever 211 of the unlocking device 210 coupled thereto moves under the influence of the spring 280 back into its original position.
  • the switching element 207 now assumes a position in which the coupling lever 211 does not engage in the switching element 207 .
  • the coupling device 211 is designed without contact with the switching element 207 at the contact point 212 .
  • the switching element 207 is in a deactivated position in which the locking device 205 cannot be unlocked.
  • the component 208 comes into contact during the rotary movement about the axis of rotation 242 via a projection 292 with a further rotary part 209, which is also arranged on the axis of rotation 276.
  • the rotating part 209 is also designed to be rotationally symmetrical and has three wings 258 which can come into contact with the projection 292 of the component 208 .
  • the rotating part 209 with the wings 258 represents a stop contour which can be taken along by the component 208 .
  • the component 208 can also be understood as a driver.
  • the rotary movement of the rotary part 209 continues in a rotary movement of the switching element 207 and the control contour 215. Viewed 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.
  • the rotary movement of the control contour 215 causes the button 214 to move out of the recessed recess 290 again.
  • the switching element 207 was rotated by the rotation of the rotary part 209 moved further, but not so far that the switching element 207 would be in an activation position again. Rather, the switching element 207 is in a further deactivation position.
  • FIG. 22a to 22f , 23a to 23f , 24a to 24f as well as 25a to 25f show several intermediate positions during this folding movement of the folding sliding door 2.
  • the setting contour 218 is now actively moved about the axis of rotation 247 by the user.
  • the rolling body 217 is thereby again pushed out of the minimum 260 and moved back in the direction of the original position.
  • the ejection force accumulator 204 is recharged.
  • the component 208 is pivoted back about the axis of rotation 242 . Since the button 214 is no longer in the detent trough 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. At the same time, the button 214 also rotates the control contour 215 and thus the switching element 207 until the tip of the Button 214 is again arranged in the original locking recess 291 of the control contour 215, and the switching element 207 is in the activation position (cf Figure 25c and 25d ). The locking device 205 could now be unlocked again.
  • the folding sliding door 2 is based on the position according to Figures 25a to 25f folded further and possibly stowed in a cavity 26 in the furniture body 15 (cf Figures 1a to 1d ).
  • the folding and sliding door 2 is then returned to the original closed position.
  • the position of the components of the locking device 205 no longer changes.
  • the Figures 26a to 26f , 27a to 27f and 28a to 28f show a different movement scenario. Specifically, when or immediately after the movable furniture part 2 is ejected, the user decides to actively move the furniture part 2 back into the original closed position ("emergency closing"). For this purpose, the user exerts a force 63 on the furniture part 2 in the direction of the closed position. As a result, the rolling element 217 is pushed back into the original position at the setting contour 218, namely along the section of the control contour 218 on which the rolling element 217 has moved until the movement is reversed. The ejection force accumulator 204 is immediately charged again.
  • the component 208 is pivoted back about the axis of rotation 242 again.
  • the stylus 214 rotates under the influence of the spring 213 the control contour 215 and thus the switching element 207 further.
  • the switching element 207 is still in a deactivated position, in which the coupling lever 211 does not yet engage in the switching element 207.
  • the switching element 207 is rotated even further, so that it is then in the activation position.
  • the coupling lever 211 of the unlocking device 210 is pressed in the opposite direction, so that the coupling lever 211 cannot initially engage in the switching element 207 .
  • the movement of the furniture part 2 from the closed position into the overpressure position during emergency closing means that the locking device 205 is not unlocked immediately. Only when the user lets go of the furniture part 2 does the unlocking device 210 move back into the original position (cf Figure 15d ) back, and the coupling lever 211 can engage in the switching element 207.
  • the ejection element 203 is connected at a first end to the setting contour 218 and at second ends 223, on which rolling elements are arranged, to the fitting part 224.
  • the rolling elements are slidably mounted in grooves 254.
  • a stabilization device 238 is also provided in this exemplary embodiment to prevent the ejection force accumulator 204 from buckling.
  • control contour 215, the switching element 207 and the rotary part 209 are arranged in a rotationally fixed manner on a common switching axis 276. This means that rotating one of these components will cause the other components to rotate.
  • the locking recesses 290 and 291 and the flanks 248 of the control contour 215, the locking projections 277 of the switching element 207 and the wings 258 of the rotating part 209 are also clearly visible.
