Description

  The invention relates to an ejecting device for a movable furniture part, wherein at least one eject element for ejecting the movable furniture part from the closed position to the open position and the movable furniture part from the closed position to the open position. At least one ejector accumulator for applying a force to the at least one ejector element at the time of ejecting, and at least one for locking the at least one ejector element against a force load by the at least one ejector accumulator A locking device is provided, wherein at least one locking device is unlockable by over-pressing the movable furniture part to an over-pressing position located behind the closed position in the closing direction. Regarding the device. The invention further relates to furniture comprising a furniture body, at least one furniture part movable relative to the furniture body, and at least one such ejecting device.

  The ejecting device described in the superordinate concept part of claim 1 is publicly known, for example, based on WO 2013/106873 (WO 2013/106873 A1). The underlying problem in this ejector is that the locking device is unintentionally re-unlocked and the movable furniture part is newly ejected by the ejecting device from the closed position to the open position. The desire is to prevent the movement of the movable furniture part from the open position to the closed position.

  Several solutions are already known in the prior art for solving this problem. In WO 2013/106873, for example, an anti-push device is realized by a locking element preventing movement of the movable furniture part to an over-pressed position when the movable furniture part reaches a closed position. Has been done.

  However, this solution has two drawbacks. That is, on the one hand, part of the energy used for the closing movement of the movable furniture part must be diverted in order to trigger the anti-tamping device. However, this runs counter to the desire to achieve as harmonious and soft closure movement as possible. This is because the closing movement must provide more energy than is originally required. On the other hand, the user may not be aware that the eject device is provided with the push-in prevention device and may damage the lock element or the push-in prevention device by an erroneous operation.

  It is therefore the object of the invention to provide an anti-tampering device, which is an improvement over the prior art, and which comprises an anti-tampering device which avoids the particular disadvantages described. It is to provide an eject device. Another object of the present invention is to provide furniture equipped with such an eject device according to the present invention.

  These problems are solved by the features of claims 1 and 14.

  Thus, the ejecting device according to the invention is provided with at least one switching element operatively connected to at least one locking device, the switching element comprising at least one unlocking device to which at least one locking device can be unlocked. It has an actuated position and at least one deactuated position in which at least one locking device cannot be unlocked, the at least one switching element ejecting the movable furniture part from the closed position to the open position. It is proposed to be movable to at least one inactive position at times and / or by unlocking at least one locking device.

  The at least one switching element is not unlockable by the ejecting of the movable furniture part and / or by being unlocked by the unlocking of the at least one locking device, so that the locking device is thus unlockable As a result, the anti-tampering device, i.e. the unintentional unlocking of the locking device, is no longer activated by the opening movement of the movable furniture part, as was done in the prior art, but by the closing movement of the movable furniture part. Guaranteed to be made. In other words, it is not necessary to branch off some of the closing energy in order to activate the push-in prevention device.

  Furthermore, it is no longer prevented that the movable furniture part is moved to the over-pressed position. The solution according to the invention rather allows the movement of the movable furniture part from the closed position to the over-pressed position. The at least one switching element in the at least one inactive position ensures that at least at the beginning of the movement of the movable furniture part to the overpressed position, the at least one locking device is not unlockable during this movement. .. Mechanical damage to the anti-tamper device is prevented.

  The movement of the at least one switching element to the at least one inactive position during the ejection of the movable furniture part from the closed position to the open position is provided, for example, by means of a coupling device, via which at least one coupling element is provided. One switching element can be connected indirectly or directly to the at least one eject element, preferably the connecting device then comprises a driver and a stop contour, particularly preferably a stop at this time. This can be realized by forming the contour as an elongated hole in which the driver is movably supported. Thus, in this case, the movement of the eject element is used to move the at least one switching element to the at least one inactive position. However, this is not necessary. Similarly, it can be expressed as follows. That is, the at least one switching element is indeed moved during the ejection of the movable furniture part to the at least one inactive position, but is moved independently of the movement of the at least one ejection element.

  According to a preferred embodiment of the invention, the at least one locking device comprises at least one unlocking device, the at least one unlocking device at least one unlocking element on the at least one switching element. It has been proposed to include at least one coupling device for coupling the device. The at least one coupling device of the at least one unlocking device then has at least one contact point, the at least one coupling device being in the at least one operating position via the at least one contact point. May be configured to contact the at least one switching element and not to contact the at least one switching element at the at least one contact point in the at least one inactive position. In this case, the at least one switching element in the at least one actuated position provides a counter, on which at least one unlocking device can be supported for unlocking the locking device. In the at least one deactivated position of the at least one switching element, this corresponding support is absent, so that the at least one unlocking device has no engagement effect.

  In an embodiment which has proved to be more suitable, at least one return device is provided, via which the at least one switching element is movable from the closed position to the open position. After the ejection of the furniture part or the unlocking of the at least one locking device, it is movable from at least one inactive position to at least one active position.

  At what point in time, or at which position of the furniture part movable relative to the furniture body, at least one return device is moved from the inactive position to the operating position after ejection or after unlocking of at least one switching element. Whether to move is not important at this time. The movement of the at least one switching element from the at least one inactive position to the at least one operating position may thus only take place, for example, when the closed position of the movable furniture part is newly reached. The movement of the at least one switching element also does not have to be performed by the return device. In principle, it is also conceivable that the user manually moves the at least one switching element back into the at least one operating position.

  However, if at least one return device is provided, the at least one return device includes a timer, via which the at least one switching element is movable from the closed position to the open position. After the ejecting of the furniture part of the vehicle or the unlocking of the at least one locking device, it is staggered from at least one inactive position to at least one active position, preferably the timer is at least It has been found suitable to include one energy store and at least one shock absorber acting against at least one energy store.

  Alternatively or additionally, at least one return device comprises a sensing device for sensing the relative position of the movable furniture part with respect to the furniture body, and at least one switching element at least It may be proposed to be movable by at least one return device from at least one inactive position to at least one active position in relation to the set position and the relative position detected by the detection device. The "relative position of the movable furniture part" with respect to the furniture body can mean, for example, when the movable furniture part is a drawer, a prescribed distance of the front decorative plate of this drawer from the end face of the furniture part. When the movable furniture part is formed as a folding door or a folding sliding door including at least a first door and at least one second door, the term "relative position of the movable furniture part" with respect to the furniture body is referred to. Can also mean a defined angular position relative to both doors.

  In another preferred embodiment of the invention, the at least one locking device comprises at least one lever arm pivotably supported and / or is formably and / or forceably lockable. is there. The form-locking connection can be realized, for example, by a locking projection which engages a pin or the like from behind.

  In an embodiment which has proved to be more suitable, a conversion device is provided, which conversion device is arranged between the at least one ejector and the at least one ejector element, preferably The conversion device then comprises at least one rolling element and at least one adjusting contour, along which the at least one rolling element is movable. The embodiment in which the conversion device comprises rolling elements and an adjusting contour is particularly suitable. As a result of the configuration of the adjusting contour, a defined course of movement of the at least one eject element can be realized. Due to the arrangement of the surfaces with different inclinations along which the rolling elements run one after the other, it is possible, for example, to realize different acceleration and braking stages.

  In an embodiment provided in a special form, the ejecting device is used in connection with a movable furniture part which is designed as a folding door or a sliding sliding door, the folding door or the folding sliding door being at least 1 A first door and at least one second door, and the at least one eject element comprises a folding door or a folding sliding door, the at least two doors being arranged in a common closing plane. From the position, at least two doors are configured to eject into an open position that forms an angle other than 180 ° with respect to each other.

  In this case, in yet another embodiment, the ejecting device comprises at least one fitting for mounting the ejecting device on the first door, and the at least one ejecting element is supported on the at least one fitting. And at least one eject element is at least one for connecting the at least one eject element to the second door when the folding door or folding sliding door is bent from the closed position to the open position. Have a device.

  This embodiment ensures that the folding door or the folding sliding door is not ejected or bent openly between the two doors and not between the folding door or the folding sliding door and the furniture body. This has two important advantages. Thus, on the one hand, a relatively small lever length is required if at least one eject element is designed as a lever. This makes it possible to obtain a comparatively small structural shape as compared with the prior art. On the other hand, during ejection there is always an equal opening angle between the doors, regardless of the door dimensions.

  If an unlocking device for the locking device is provided, it is likewise not necessary for the unlocking device to form a contact with the furniture body for unlocking. Rather, the unlocking device is or is at least connectable to the first door and the second door when the at least one locking device is unlocked, whereby the unlocking device comprises at least one unlocking device. It may be possible to detect a relative angular change between the two doors when the lock device is unlocked. With such a configuration, the eject device can be arranged at an arbitrary position between both doors. If this is not the case, care must be taken to arrange the ejectors on both doors so that the ejectors have a slight distance to the end face of the furniture body.

  As mentioned at the outset, the furniture body and 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 movable body from the closed position to the open position. Furniture with at least one ejecting device according to the invention for ejecting a furniture part, wherein preferably at least one movable furniture part is formed as a folding door or a folding sliding door. There is also a need for protection against furniture, in which the furniture body has a hollow chamber, in particular a hollow shape, for housing the at least one folding door or folding sliding door in the folded position.

  In particular, in the embodiment provided in connection with the invention, a drive is then provided, which drive is such that at least one movable furniture part automatically transitions from the open position to the closed position. Has been formed. At this time, the two cases may be different from each other. That is, in one of the first cases, the movable furniture part is immediately moved back into the closed position by the user's hand after the ejection, and in the second case, at least one movable furniture part is It is automatically moved to the closed position. In the first case, the anti-tampering device is actuated according to the invention, wherein the at least one switching element is at least 1 at the beginning of the movement of the movable furniture part to at least the closed or overpressed position. In the non-actuated position, whereby at least one locking device cannot be unlocked. In the second case, on the other hand, it is completely unnecessary to provide a push-in prevention device. This is because the drive always moves the movable furniture part with the same force to the closed position. The custom design of this force makes it possible to prevent the movement of the movable furniture part from the closed position to the over-pressed position without the need for anti-tampering devices therefor. In other words, the invention covers in particular the case of "emergency closure" in the sense that the user wants to change his / her feelings about the desire to open and to reclose the movable furniture part immediately after or even during the eject. There is. That is, in such a case, the push-in prevention device is always active so that the lock device cannot be unlocked.

  In the following, further details and advantages of the present invention will be detailed by the description of the drawings with reference to the embodiments shown in the drawings.

  1 a to 1 d show a furniture 25 including a furniture body 15. A part of the furniture body 15 can be covered outwardly by means of two folding slide doors 2 each including one first door 19 and one second door 20, at which time both doors 19 , 20 are pivotally connected to each other. In the case of FIG. 1a, both folding sliding doors 2 are in the closed position, in which both doors 19, 20 are arranged in a common closing plane. In the case of FIG. 1b, one of the two folding slide doors 2 (the right folding slide door 2) is in the open position, in which the two doors 19, 20 form an angle different from each other by 180 °. ing. On the other hand, the two doors 19 and 20 of the other folding slide door 2 form an angle 21 of 180 ° with each other. In the case of FIGS. 1c and 1d, both folding sliding doors 2 are in the folded position, the folding sliding doors 2 shown in FIG. 1c then being arranged outside the furniture body 15 and The folding slide door 2 shown in is arranged inside the furniture main body 15. In order to arrange the folding slide door 2 inside the furniture body 15, a hollow chamber 26 formed in a hollow shape is provided.

  At least a part of the furniture 25 that can be covered by the folding slide door 2 is provided with a kitchen 28 having an under cabinet and an over cabinet including, for example, a drawer.

  One of the two doors 19 and 20 of the folding slide door 2 is pivotally arranged on the holder. Reference numeral 19 is attached to this door. Furthermore, the two doors 19, 20 are pivotally connected to each other via a hinge 30 (see FIG. 1c). The door 20, which is not pivotally connected to the holding body, is connected to a carriage 31, and the carriage 31 is movably supported along a rail 32. The rail 32 is arranged in the upper region of the furniture body 15.

  Reference numerals 6 (depth), 34 (width), and 33 (height) are attached to the three spatial directions.

  Between the two doors 19, 20 of the folding sliding door 2, the two doors 19, 20 form an angle 21 different from 180 ° with respect to each other from a closed position in which the two doors 19, 20 are arranged in a common closing plane. One ejecting device 1 for ejecting the folding slide doors 2 is arranged at each open position. The ejecting device 1 partially cooperates with the end surface 29 of the furniture body 15.

  2a to 12b, a first preferred embodiment of the eject device 1 is described. A second embodiment of the eject device 101 is described in Figures 13a to 13c. 15a to 28f, a third embodiment of the eject device 201 is described.

  2a to 2c, the ejecting device 1 according to the first preferred embodiment is shown in a locked closed position, in which parts of the folding sliding doors are pivoted relative to one another via a central hinge 30. Doors 19 and 20 which are fixedly connected are shown schematically. The hinge axis of the central hinge 30 is labeled 35. The ejecting device 1 is connected to the doors 19, 20 via a fitting 40 (see FIG. 2c) on the one hand and a fitting 24 on the other hand.

  A first portion of the eject device 1 is arranged on one door 19, and a second portion of the eject device 1 is arranged on the other door 20.

  The first part of the ejection device 1 comprises an ejection force store 4 with two compression springs, both compression springs being arranged in a stabilizer 38 (see also FIG. 3). The stabilizer 38 prevents the compression spring from bending inwardly during compression. Each stabilizer 38 is arranged between the base 37 and the slider 36. The base 37 is fixedly connected to the door 19 via a base plate 40. The slider 36 can slide relative to the base plate 40, i.e. on the one hand under the influence of the energy stored in the compression spring of the ejector accumulator 4 and on the other hand by the folding of the doors 19, 20. It can slide relative to the base plate 40 under the influence of manual action on the device 1.

  The slider 36 is located at the first end on which the stabilizer 38 is supported and on the opposite side on which the two rolling elements 17 are rotatably supported about a shaft 41 (see also FIG. 3). A second end that is open. Each rolling element 17 is supported on an adjusting contour 18 which is rotatably supported about a rotation axis 47.

  In order to prevent the slider 36 from being lifted from the fixture 40, another rolling element 52 is arranged between the two rolling elements 17 on the shaft 41, and the rolling element 52 includes the groove 53 of the member 42. It is supported inside so that it can be slid within it. The member 42 is arranged between the two adjusting contours 18.

  The adjusting contour 18 and the rolling elements 17 form a conversion device which is arranged between the ejector accumulator 4 and the two ejecting elements 3. The eject element 3 is forcibly connected to the adjusting contour 18 in its movement. That is, the eject element 3 also performs such a rotation when the adjusting contour 18 rotates about the rotation axis 47.

  Furthermore, the eject elements 3 each have at least one device for connecting the eject element 3 with one of the doors 19, 20 of the doors 19 or 20. In detail, this device for connection comprises a preferably pin-shaped end portion 23, which is slidably supported in a groove 54 of the fitting 24 (see also FIG. 3). ing. That is, by the rotation of the eject element 3 about the rotation axis 47, the door 20 is continuously swung about the rotation axis 35 relative to the door 19. On the contrary, the relative movement between the doors 19 and 20 causes the eject element 3 to also rotate.

  In general terms, the converter serves in particular to convert the linear movement of the slider 36 into the swiveling movement of the eject element 3 and, conversely, to the swiveling movement of the eject element 3 into the linear movement of the slider 36. Upon conversion of the linear movement of the slider 36 into the swiveling movement of the eject element 3, the eject accumulator 4 is discharged (releasing its force and relaxing). In the opposite direction, i.e. during the conversion of the relative movement of the doors 19, 20 or the attachments 40, 24 relative to the linear movement of the slider 36, the ejector accumulator 4 is charged (accumulates and tensions).

  Due to the configuration of the adjusting contour 18, the movement of the eject element 3 can also be precisely controlled. In this way, for example, firstly, the acceleration phase can be obtained at the start of the ejecting movement. This acceleration phase can be followed by a continuous braking phase before the ejector 4 is charged.

  In order to obtain a compact constructional form of the ejecting device 1, the fitting 40 and the door 19 are each provided with notches 46 (see also FIG. 3), which cutouts 46 allow the adjusting contour 18 to pivot. It can be at least partially housed therein.

  Further, the eject device 1 includes a lock device 5 for locking the eject element 3 against the force load by the eject accumulator 4. At this time, the lock device 5 includes the lever arm 16 supported by the slider 36 so as to be pivotable about the rotation shaft 57.

  The locking device 5 is pressed in the direction of the fixture 40 by a holding device (see also subsequent figures). The hold-down device comprises a spring 68 which, on the one hand, is directly or indirectly connected to the fixture 40, which connection is then via the base 37 as in the case shown. It can be carried out. On the other hand, the spring 68 is connected to the end of the lever 67, whereupon a lateral pin is also arranged at the lever end, which lateral pin acts on the projection 45 of the locking device 5. The spring 68 is formed as a tension spring, and the spring 68 is lightly preloaded. When the locking device 5 is pivoted away from the mount 40, the spring 68 is relatively tight and exerts a relatively large force in the direction of the mount 40. As a result, the locking device 5 has a tendency to move towards the fitting 40 in any position. Alternatively or additionally, the holding device may be formed by an axial spring in the vicinity of the axis of rotation 57.

  The lever arm 16 is formed of two parts in the case shown (see also FIG. 3). Equally well, the lever arm 16 may be formed in one piece. A locking projection 44 is formed on the free end of the lever arm 16 and can be locked on the pin 43 in a form-fitting or force-fitting manner. The pin 43 is fixedly arranged on the base plate 40. Instead of the locking solution shown, other locking solutions are possible.

  To unlock the locking device 5, two unlocking devices 10 are provided. The both lock releasing devices 10 are supported by the lever arm 16 so as to be rotatable around a rotation shaft 48. Furthermore, the unlocking device 10 has a free end, which can come into contact with the end face 29 of the furniture body 15 via a contact point 51 (see also subsequent figures).

  Furthermore, the ejecting device 1 comprises, as main elements, a switching element 7 which is operatively connected to the locking device 5, which switching element 7 is in the operating position in which the locking device 5 can be unlocked and the locking device 5. Has an inoperative position in which it cannot be unlocked, the switching element 7 being movable to the inactive position when the movable furniture part 2 is ejected from the closed position to the open position.

  In particular, the switching element 7 is embodied as a slider in the case shown, which is held linearly slidably on the base plate 40 (see in particular FIGS. 2c and 3).

  A connecting device is provided which is capable of indirectly connecting the switching element 7 to the ejecting element 3, the connecting device including a driver 8 and a stop contour 9 formed as an elongated hole. The driver 8 is movably supported in the stopper contour 9. In the case shown, the driver 8 is embodied as a pin, which is supported on a slider 36 on which the ejector 4 acts. The slot 9 is formed in the switching element 7. However, it is equally possible for the slider 36 to include the slot 9 and the switching element 7 to include the driver 8. Furthermore, the coupling device can have a completely different configuration.

  Furthermore, the unlocking device 10 has a connecting device 11 for connecting the unlocking device 10 to the switching element 7. In particular, these connecting devices 11 each have a contact point 12, in which case the connecting device 11 contacts the switching element 7 in the operating position via the contact point 12 and in the inactive position. It is formed so as not to contact the switching element 7.

  A return device is provided to move the switching element 7 back from the inoperative position to the operating position again after ejecting the folding sliding door 2 from the closed position to the open position. The return device then includes a timer, via which the switching element 7 is displaced in time to the actuated position. The timer includes a power storage device 13 and a shock absorber 14 that acts against the power storage device 13. As can be seen in particular from FIG. 2c, the energy store 13 comprises two compression springs, which are arranged between the first end of the switching element 7 and the base plate 40. The shock absorber 14, which is embodied as a fluid shock absorber with a piston-cylinder unit, is arranged between the second end of the switching element 7 and the member 39. That is, a force is applied to the slider 7 from one side by the power storage device 13 and from the other side by the shock absorber 14.

  In the locked rest position of the ejecting device 1, a balance occurs between the energy store 13 and the shock absorber 14 such that the energy store 13 is discharged and the shock absorber 14 is pushed in. ing. This position is shown in Figures 4a-4c and 12a. The locking device 5 is locked in this position. On the one hand, the unlocking device 10 is in contact with the end face 29 of the furniture body 15 via the contact points 51, and on the other side with the switching element 7 via the contact points 12 (see FIG. 4c).

  When the ejecting device 1 or the movable furniture part 2 connected to the ejecting device 1 is moved to the over-pressed position (see Figures 5a to 5c) located behind the closed position in the closing direction, the unlocking device Reference numeral 10 unlocks the lock device 5 by a force load on the connecting shaft 48. As a result, the locking projection 44 has sufficient play with the locking pin 43 to release the form and force connections.

  The user continues to release the eject device 1 or the movable furniture part 2 connected to the eject device 1 (FIGS. 6a to 6c). This allows the force stored in the ejector store 4 to be released, which causes the slider 36 to perform a linear movement. The switching element 7 is moved together via the driver 8 which abuts the first stop surface 58 of the slot 9 after a short time. This causes the switching element 7 to be separated from the unlocking device 10 and the contact point 12 of the coupling device 11 (see in particular FIG. 6c). At the same time, the accumulator 13 acting on the switching element 7 of the timer is compressed and the shock absorber 14 is relaxed.

  The slider 36 continuously applies a force via the rolling elements 17 to the adjusting contour 18 and thus to the eject element 3. As a result, the adjusting contour 18 and the eject element 3 are swiveled around the rotation axis 47. By means of the coupling device 23, 24 of the eject element 3, the fitting 24, or the door 19; 20 connected to the fitting 24, is swiveled about the axis of rotation 35, that is to say the door 19, 20 is a common closing plane. Starting from the position arranged in the position, the doors 19 and 20 are swiveled to a position in which the doors 19 and 20 form an angle different from 180 ° (see especially FIG. 6a).

  The eject movement ends when the eject accumulator 4 is completely discharged. The position occupied by the ejecting device 1 at this point is shown in Figures 7a to 7d. As can be seen in particular from FIG. 7c, the rolling element 17 is in this position in the minimum 60 contained by the adjusting contour 18. Usually, the user now wants to further open the movable furniture part 2. To that end, the user applies a force 61 to the movable furniture part 2. When the movable furniture part 2 is the folding slide door 2, the folding slide door 2 is moved in the direction of the position where the folding slide door 2 is folded by the force load. As a result, the eject element 3 or the adjusting contour 18 connected to the eject element 3 is further swiveled around the rotation axis 47. The adjusting contour 18 is in contact with the rolling elements 17 of the slider 36, so that the slider 36 is moved back towards the starting position which the slider 36 occupies in the locked state. As a result, the eject power storage device 4 is continuously charged again.

  During this charge transfer, the return device becomes active. That is, the force stored in the energy store 13 is released again, and the switching element 7 is moved back against its load by the shock absorber 14 back into its original operating position. The anti-tamping device (Durchdrueckschutz), which is activated during the ejection of the movable furniture part 2 from the closed position to the open position, is thus deactivated again during the charging movement of the ejecting device 1.

  8a and 8b show the ejecting device 1 or the movable furniture part 2 in a folded state. Starting from this position, the furniture part 2 can now be moved into the hollow chamber 26 in the furniture body 15. The eject device 1 is in the semi-locked state in this position. This state is realized by the ejecting device 1 having to be stored in a space-saving manner (verstauen). That is, the unlock device 10 is originally located at the position where the lock device 5 is unlocked. This is achieved by the unlocking device 10 being "crushed" between the switching element 7 and the door 20. Now when the folding slide door 2 is redeployed, the locking device 5 is immediately re-locked. That is, the movement of the slider 36 is hindered by the adjusting contour 18.

  FIG. 9 shows the ejecting device 1 in an intermediate position during the transition from the folded position shown in FIG. 8b to the closed position. As can be seen from the drawing, the locking device 5 is locked. A force 62 is applied to the eject device 1 or the doors 19 and 20 connected to the eject device 1. According to a preferred embodiment of the invention, this force 62 is provided by a drive device 30 configured to automatically move the movable furniture part 2 to the closed position. The drive device 30 may be, for example, a central hinge connecting the doors 19 and 20 to each other. Alternatively or additionally, however, a separate drive can also be provided.

  In addition, a drive 49 may also be provided, which drives the door set from the hollow space 26 to a position outside the hollow space 26. The drive unit 30 may also consist of two parts, the first part causing the open bending of the door set from the folded position to the intermediate position, and the second part from the intermediate position to the final position. Cause a transition to a closed position. The force provided by the drive 30 can be adjusted precisely so that the movable furniture part 2 always moves at the same speed to the closed position. The indentation prevention device is not necessary in this case. This is because the force can be set so that the movable furniture part no longer moves from the closed position to the over-pressed position.

  However, it is also desired that if the ejecting device 1 is unintentionally triggered or if the user changes his mind immediately after unlocking or during ejecting and immediately again moves the movable furniture part 2 to the closed position. In some cases, it may occur. This situation is also called "emergency closure". This situation is illustrated in Figures 10a-10c, 11 and 12b. That is, the user applies force 63 to the ejecting device 1 by hand. That is, the ejector 4 is immediately recharged, at which time the rolling elements 17 are moved back in the opposite direction along the adjusting contour 18 and the locking device 5 is moved towards the locking position. However, due to the return device timer, the anti-tamper device is still active in this situation. That is, the switching element 7 is in the inactive position. That is, the unlocking device 10 is formed so as not to contact the switching element 7. When the user applies that force 63 very high, the movable furniture part 2 is moved beyond the closed position and into the overpressed position (see FIG. 11). However, because the unlocking device 10 cannot be supported on the switching element 7, the locking device 5 remains locked. That is, the lock device 5 cannot be unlocked. After a certain amount of time, the switching element 7 is moved back to its operating position. However, at this time, the user normally no longer applies force to the ejecting device 1. The eject device 1 remains locked.

  13a to 13c show a second preferred embodiment of the ejecting device 101, namely in the locked closed position (FIG. 13a), in the over-pressed position (FIG. 13b) and immediately after unlocking. It is shown in the position (Fig. 13c).

  The main difference in the present embodiment is that the unlocking device 110 is coupled to the first door 19 and the second door 20 or both attachments 40 and 24 when the locking device 5 is unlocked. As a result, the unlocking device 110 can detect a relative angular change between the two doors 19 and 20 when the locking device 5 is unlocked. This is, for example, the rope 55, which is tensioned in the closed position between one end 69 of the unlocking device 110 and the connection point 56 on the fitting 24. When the eject device 101 is now moved from the closed position to the over-pressed position, the unlocking device 110 is moved towards the locking device 5. The unlocking device 110 is at the same time supported on the switching element 7, which has been described in detail in connection with the first embodiment, so that the unlocking of the locking device 5 takes place. In other words, it is no longer necessary to contact the furniture body 15 in order to carry out the unlocking. This has the great advantage that the ejecting device 101 can be arranged at any desired location on the movable furniture part 2.

  14a and 14b show a furniture 27 formed as an over cabinet for a kitchen, which furniture 27 can be closed outwards by a folding flap 22. The folding flap 22 is formed by two partial flaps 65, 66, which are pivotally connected to each other via a central hinge 30. Furthermore, the partial flap 66 is pivotally connected to the furniture body 64 of the furniture 27. The partial flap 65 is likewise arranged on the furniture body 64 and is moved via the adjusting unit 50 which comprises a power store. The ejecting device 1 may be arranged between the partial flaps 65, 66 in order to eject the folding flap 22 from the closed position of the same or common plane to the open bent position. Alternatively, of course, it is also possible to use the eject device 101 or 201 (see subsequent figures).

  The ejecting device according to the invention can also be used in other furniture, for example drawers.

  15a to 28f show a third preferred embodiment of the eject device 201. With regard to the basic principle, this eject device 201 functions like the eject device 1. However, there are a series of differences, especially in the switching element 207 and in the elements connected to the switching element 207.

  The eject device 201 is arranged between the doors 19 and 20 of the folding slide door 2. At this time, the ejecting device 201 is connected to the door 19 via the fitting 240 on the one hand and to the door 20 via the fitting 244 on the other hand. The reverse arrangement of the doors 19, 20 is also possible.

  The closed position of the folding slide door 2 is shown in FIG. 15a. In this position, the ejecting device 201 is in contact with the end surface 29 of the furniture body 15 (see FIGS. 1a to 1d) via the unlocking device 210. As can be seen in particular from Fig. 15d, the unlocking device 210 comprises a contact lever 283, which is connected to the ejecting device 201 via two pivotally supported fixed levers 284, 279. There is. The fixed levers 284 and 279 form an acute angle with each other. The fixed levers 284 and 279 can be swung around the rotation points 285 and 278 in the eject device 201. The contact lever 283 is coupled to the fixed levers 284 and 279 via rotation points 282 and 281. The distance between the rotation points 281 and 283 is smaller than the distance between the rotation points 278 and 285. A spring 280 is tensioned between the fixed levers 284 and 279. This spring 280 acts so that the locking levers 284, 279 have the smallest possible distance from each other, whereby the contact lever 283 is pushed away from the ejecting device 201 and in the closed position on the end face 29 of the furniture body 15. Are in contact. A contact point 251 is attached to a contact point of the contact lever 283 with the end surface 29 of the furniture body 15. The end portion of the contact lever 283 where the contact point 251 is arranged is located on the opposite side of the end portion of the contact lever 283 where the rotation points 281 and 282 are provided.

  The unlocking device 210 has a further lever 211, which on the one hand is connected to a fixed lever 284 via a pivot point 286 and, on the other hand, has a free lever end. There is. The free lever end is shaped like a hook and has a U-shaped contact point 212.

  The ejecting device 201 further includes a switching element 207, which is rotatably supported about a switching shaft 276. The switching element 207 is rotationally symmetrical. The switching element 207 likewise comprises hook-shaped locking projections 277, which can cooperate with the lever 211 of the unlocking device 210. This situation is shown in Figure 15d. That is, the lever 211 is in contact with the switching element 207 via the contact point 212. This is the operating position of the switching element 207. The lever 211 is a coupling device for coupling the unlocking device 210 with the switching element 207.

  In the present embodiment of the eject device 201, the lock device 205 is formed as a pivotally supported lever 216 that is pivotally supported by the eject device 201 about a rotation shaft 257. The locking device 205 includes a locking protrusion 244. This locking projection 244 can engage within a corresponding locking projection 287, as shown in Figure 15e. The locking protrusion 287 is formed on the member 208 rotatably supported by the eject device 201 about the rotation shaft 242. A further rolling element 217 is supported by the member 208 around the rotary shaft 241. That is, this rolling element 217 can move on a circular orbit centered on the rotation point 242.

  A force is applied to the rolling element 217 from the ejector accumulator 204 via the slider 236. Furthermore, the rolling elements 217 are in contact with the adjusting contour 218, which can be seen particularly well in FIG. 15f. The adjustment contour 218 has one minimum 260 and two adjacent maximums 289,288. The adjusting contour 218 is rotatably supported by the ejecting device 201 about the rotation shaft 247.

  A non-rotatable ejecting element 203, which is formed as a fork-shaped lever, is connected to the adjusting contour 218. When the adjusting contour 218 moves around the rotation axis 247, the eject element 203 is forcibly moved together, and when the eject element 203 moves conversely, the adjusting contour 218 also moves together.

  The adjusting contour 218 and the rolling element 217 together form a converter, which is arranged between the ejector accumulator 204 and the ejector element 203.

  The locking device 205 is coupled to the switching element 207 via the mechanism shown in particular in FIG. 15c. A control contour 215 is non-rotatably arranged on the switching shaft 276 of the switching element 207. The control contour 215 is likewise rotationally symmetrical. A contact 214 may be supported on the control contour 215, which contact 214 is connected to the ejecting device 201 via two pivoting levers 271, 274. On the other hand, the turning lever 271 is supported by the ejecting device 201 so as to be rotatable around a rotation shaft 272. On the other hand, the swiveling lever 271 is connected to the contactor 214 via a rotation point 270. Correspondingly, the swiveling lever 274 is, on the one hand, rotatably supported on the ejecting device 201 about a rotary shaft 273. On the other hand, the swivel lever 274 is connected to the contact 214 via a rotation point 275. The contact 214 is pressed in the direction of the control contour 215 by a spring 213 arranged between the ejecting device 201 and the contact 214. The contact 214 is further kinematically connected to the locking device 205.

  The user now exerts a force on the folding sliding door 2 in the closing direction 6, whereby the folding sliding door 2 is unlocked when it moves from the closing position to the over-pressed position which is arranged behind the closing position in the closing direction 6. The contact lever 283 of the device 210 is moved in the direction of the eject device 201 (see Figures 16a to 16f, especially Figure 16d). As a result, the connecting lever 211 is continuously pulled in the opposite direction, that is, toward the end surface 29 of the furniture body 15. Engagement of lever 211 in switching element 207 causes switching element 207 to rotate about axis of rotation 276.

  This rotary movement of the switching element 207 also causes a rotation of the control contour 215 (see FIG. 16c). This is because the switching element 207 and the control contour 215 are arranged on a common axis of rotation 276. In the starting position shown in FIG. 15c, the tip of the contact 214 is in the first locking recess 291. When the control contour 215 is now rotated, the control contour 215 pushes the contact 214 out of the locking recess 291 along the side surface 248. This causes the contact 214 to move away from the control contour 215.

  The movement of the contact 214 continuously causes the lever 216 of the locking device 205 to pivot about the axis of rotation 257, which causes the lever 216 to move away from the connecting member 208 and unlock. It

  The maximum over-pressed position is shown in Figures 17a to 17f. The lever 216 of the locking device 205 has completely released the member 208. At the same time, the tip of the contactor 214, which is in contact with the control contour 215, has moved beyond the side surface 248 and into the second locking recess 290. The contact 214 is stably held in the locking recess 290. As a result, the lever 216 of the locking device 205 is also stably held in the unlocked position.

  When the user has now completely released the folding slide door 2, the member 208 can swivel about the axis of rotation 242 under the influence of the force stored in the eject energy store 204 (FIGS. 18a-). See Figure 18f). The contact lever 283 and the connecting lever 211 of the unlocking device 210, which is connected to the contact lever 283, returns to its original position and moves again under the influence of the spring 280. As can be seen from a comparison of FIGS. 15d and 18d, the switching element 207 is now in a position in which the connecting lever 211 is not engaged in the switching element 207. In other words, the connecting lever 211 is formed so as not to come into contact with the switching element 207 at the contact point 212. The switching element 207 is in the inactive position in which the locking device 205 cannot be unlocked.

  As can be seen from the further series of Figures 19a to 19f, 20a to 20f, and 21a to 21f, the rolling element 217 is adjusted by releasing the force stored in the ejector store 204. It is moved along 218 in the direction of the smallest portion 260. This causes the adjusting contour 218 to pivot about the axis of rotation 247. This pivoting motion continues to the eject element 203, which continues to pivot the door 20 relative to the door 19. This moves the movable furniture part 2 from the closed position to the open position.

  As the comparison of FIGS. 19e, 20e, and 21e shows, the member 208, during a rotational movement about the rotation axis 242, has another rotation, via the projection 292, also arranged on the rotation axis 276. Contact the portion 209. The rotating part 209 is likewise rotationally symmetrical and has three vanes 258, which can come into contact with the projection 292 of the member 208. The rotating part 209 with the vanes 258 is a stop profile that can be carried by the member 208. As a result, the member 208 can be interpreted as an entrainment body. The rotary movement of the rotary part 209 subsequently causes the switching element 207 and the control contour 215 to rotate. Thus, taken as a whole, the drive body 208 and the stop contour 209 form a coupling device for coupling the switching element 207 to the eject element 203.

  The rotational movement of the control contour 215 causes the contactor 214 to move out of the locking recess 290 again. The switching element 207 does indeed move further due to the rotation of the rotating part 209, however, it does not move so far that the switching element 207 is again in the actuated position. Rather, the switching element 207 remains in the inactive position.

  In the position of the ejector device 201 shown in Figures 21a to 21f, the ejector accumulator 204 is completely discharged. The rolling element 217 is in the smallest part 260 of the adjusting contour 218.

  Starting from this position, the user now normally applies a force 61 to further fold the folding slide door 2. 22a to 22f, 23a to 23f, 24a to 24f, and 25a to 25f show a plurality of intermediate positions of the folding slide door 2 during this folding movement.

  At this time, the adjusting contour 218 is now actively moved by the user about the rotation axis 247. As a result, the rolling element 217 is pushed out of the minimum portion 260 again, and is moved back toward the original position. As a result, the eject power storage unit 204 is charged (tensioned) again.

  At the same time, the member 208 is swung back around the axis of rotation 242. Since the contact 214 is no longer located in the second locking recess 290, the spring 213 can again move the contact 214 and thus the lever 216 of the locking device 205 towards the starting position. At the same time, the contact element 214 also has the control contour 215 and thus the switching element 207, the tip of the contact element 214 is again arranged in the original locking recess 291 of the control contour 215 and the switching element 207 is in the operating position. Further rotation until in position (see Figures 25c and 25d). The locking device 205 can now be unlocked again.

  Normally, the folding slide door 2 is further folded from the position shown in FIGS. 25a to 25f, and is optionally housed in the hollow chamber 26 of the furniture body 15 (see FIGS. 1a to 1d).

  The folding slide door 2 is then moved back into its original closed position. At this time, the positions of the members of the locking device 205 no longer change.

  26a to 26f, 27a to 27f, and 28a to 28f show different moving situations. In other words, the user decides to actively move the furniture part 2 to the original closed position again at the time of or immediately after the ejection of the movable furniture part 2 (“emergency closing”). To that end, the user applies a force 63 to the furniture part 2 in the direction of the closed position. As a result, the rolling element 217 is pushed back in the adjusting contour 218 so as to return to its original position, that is to say, it is pushed back along the part of the control contour 218 that has moved until the rolling element 217 reverses. The eject energy store 204 is directly charged again.

  The member 208 is swung back around the rotation axis 242 again. The contacts 214 further rotate the control contour 215 and thus the switching element 207 under the influence of the spring 213. Upon reaching the closed position (see FIGS. 27a to 27f), however, the switching element 207 is still in the inactive position in which the connecting lever 211 is still not engaged in the switching element 207.

  Upon further movement in the direction of the overpressed position, the switching element 207 is indeed rotated further, which then causes the switching element 207 to be located in the actuated position. At the same time, however, the connecting lever 211 of the unlocking device 210 is pushed in the opposite direction, so that the connecting lever 211 cannot initially engage in the switching element 207. That is, the locking device 205 is not immediately unlocked by the movement of the furniture part 2 from the closed position to the over-pressed position at the time of emergency closing. Only when the user releases the furniture part 2 the unlocking device 210 again moves back into its original position (see FIG. 15d) and the connecting lever 211 can engage in the switching element 207.

  As can be seen from Figures 29a and 29b, some components of the ejector device 201 may be formed in two parts, for increased stability. This is true, for example, for the adjusting contour 218, the member 208, the lever 216 of the locking device 205, the contact 214, the locking levers 279, 284 and the control contour 215.

  As can be further seen from the drawing, the eject element 203 is connected at a first end to the adjusting contour 218 and at a second end 223 on which the rolling elements are arranged, to an attachment 224. There is. The rolling element is slidably supported in the groove 254.

  As a final remark, also in the present embodiment, the stabilizer 238 for preventing the inward bending of the eject power storage device 204 is provided.

  As can be better seen in FIGS. 30a and 30b, the control contour 215, the switching element 207 and the rotating part 209 are arranged non-rotatably on a common switching shaft 276. That is, rotation of one of these members causes rotation of the other member.

  Furthermore, the locking recesses 290, 291, the side surfaces 248 of the control contour 215, the locking projections 277 of the switching element 207, and the vanes 258 of the rotating part 209 can also be clearly seen from the drawing.
