Description
[0001] Ejection device for a movable furniture part
[0002] The invention relates to an ejection device for a movable furniture part for moving the movable furniture part from a closed position towards an open position, comprising a housing, an ejection device movable relative to the housing for transmitting force from the ejection device to the movable furniture part in the opening direction, a force storage device for applying force to the ejection device and a locking device for inhibiting a movement of the ejection device in a locking position of the locking device in the direction of the open position. Furthermore, the invention relates to an arrangement comprising two such ejection devices and a synchronization shaft, and to a piece of furniture with at least one such ejection device. Furthermore, the invention relates to a method for synchronizing two such ejection devices.
[0003] An ejection device for movable furniture parts is already known from WO 2011 / 015663 A2, wherein a locking device is guided in a guide track. If the locking device is guided by an ejection device into an incline of the locking device, the ejection device is unlocked. Synchronization in the unlocking of the locking devices takes place via the movable furniture part.
[0004] A disadvantage of the state of the art is that the synchronization is carried out by the movable furniture part in the form of a forced unlocking in the guideway, which causes increased wear of the components involved, an inharmonious opening movement of the movable furniture part and increased noise in the movement sequence of the movable furniture part.
[0005] The objective technical object of the present invention is therefore to provide an ejection device which is improved compared to the prior art, as well as an arrangement, a piece of furniture and a method in which the disadvantages of the prior art are at least partially eliminated and which are characterized in particular by a long service life, a quiet ejection process and / or a harmonious movement tra ctory of the movable furniture part.
[0006] This problem is solved by the features of claim 1.
[0007] It is therefore provided according to the invention that the ejection device comprises at least one release device separate from the locking device and the ejection device for, in particular, direct contacting of the locking device, wherein the at least one release device is pivotally arranged on the ejection device and comprises a contact contour, in particular contact surface, with which the locking device can be contacted in two mutually separate contact positions.
[0008] This makes it possible for the state of the locking device to be changed depending on a component that is independent of the actual ejection process of the movable furniture part. This provides a high degree of customization options for the locking and / or unlocking process, so that, for example, unlocking or locking of the ejection device can be initiated depending on the contact between the at least one release device and the locking device. Another positive feature is that synchronization of ejection devices can be ensured particularly favorably and, in particular, independently of a direction of movement of the ejection device for unlocking the locking device.
[0009] As stated at the outset, protection is also sought for an arrangement comprising two such ejection devices and a synchronization shaft for synchronizing the two ejection devices of the two ejection devices.
[0010] As stated at the outset, protection is also sought for a piece of furniture comprising a furniture body, at least one furniture part movable relative to the furniture body and at least one such ejection device.
[0011] As stated at the outset, protection is also sought for a method for synchronising two such ejection devices, whereby the following method steps are carried out:
[0012] - the at least one release device of a first and a second ejection device is moved into a closed position, wherein the at least two release devices contact the two locking devices in the same contact position
[0013] - the at least one release device of the first ejection device is moved from a closed position into an overpressure position and from the overpressure position back into the closed position, wherein the at least one release device of the first ejection device contacts the locking device of the first ejection device at a contact position which is separate and different from the first contact position, so that the
[0014] Locking device for activating the ejection device of the first ejection device is pivoted
[0015] - the synchronization shaft transmits the pivoting movement of the locking device of the first ejection device to the locking device of the second ejection device, wherein the locking device of the second ejection device is pivoted and releases the ejection device of the second ejection device.
[0016] Advantageous embodiments of the invention are defined in the dependent claims.
[0017] Further details and advantages of the present invention are explained in more detail below with reference to the description of the figures and to the exemplary embodiments shown in the drawings. The design features of individual embodiments of the ejection device are applicable to the other embodiments of the ejection device. These show:

[0030] Fig. 12a-12f show the ejection devices according to the embodiment shown in Fig. 12f in a view from above in a sectioned representation in the area of the laying device.
[0031] Fig. 1 shows a piece of furniture 18 comprising a furniture body 19, three furniture parts 2 in the form of drawers that are movable relative to the furniture body 19, and (concealed by the drawers) two ejection devices 1 for ejecting the drawer. The two ejection devices 1 (not shown for reasons of clarity) are arranged essentially mirror-symmetrically on the furniture body 19 (cf. Fig. 2a).
[0032] A first locking device 9 and a second locking device 9 can be unlocked (synchronously or asynchronously) essentially in a plane 29 oriented parallel to the furniture body 19 and can be designed in the same way.
[0033] The methods and arrangements on the furniture 18 described below are applicable to all embodiments of the ejection devices 1.
[0034] The movable furniture part 2 is preferably in the form of a drawer, with the ejection device 1 particularly preferably being arranged below the drawer. In general, the device can be used with other movable furniture parts 2—such as flaps or the like—or arranged to the side of the movable furniture part 2.
[0035] The ejection device 1 is fixed to a guide device for the movable furniture part 2, which preferably comprises a body rail for fastening to the furniture body 19, a drawer rail and optionally a middle rail.
[0036] Fig. 2a shows the ejection devices 1 with the housing 5 mounted and a schematically indicated synchronization shaft 17, which can generally be provided (in order to achieve synchronous unlocking and not asynchronous unlocking of the locking device 9, which is generally present without a synchronization shaft 17) or can be retrofitted via an optional interface, but is not absolutely necessary for the function on the movable furniture part 2. For example, triggering of both ejection devices 1 can be generated by exerting pressure in a central area of a furniture front of the movable furniture part 2.If only one locking device 9 is unlocked by the pressure actuation - in particular by a lateral pressure actuation on the movable furniture part 2 - then wedging of the movable furniture part 2 is prevented by the functionality of the bidirectional unlockability via a separate release device 13.
[0037] A synchronization shaft 17 is not required for the arrangement of movable furniture part 2 and two ejection devices 1 in order to properly eject the movable furniture part 2 from the furniture body 19 (despite off-center pressure being exerted on the movable furniture part 2).
[0038] In Fig. 2b the ejection devices 1 are shown in a sectional view, wherein the ejection device 1 for the movable furniture part 2 for moving the movable furniture part 2 from a closed position 3 in the direction of an open position 4 comprises an ejection device 6 which is movable relative to the housing 5 for transmitting force from the ejection device 1 to the movable furniture part 2 in the opening direction 7, a force storage device 8 for applying force to the ejection device 6 and a locking device 9 for inhibiting a movement of the ejection device 6 in a locking position 10 of the locking device 9 in the direction of the open position 4.
[0039] The ejection devices 1 each comprise a control device 12 for transmitting force from the energy storage device 8 to the ejection device 6, wherein a movement of the control device 6 in the direction of the open position 4 can be inhibited in the locking position 10 of the locking device 9.
[0040] Both ejection devices 1 shown are located in a locked position via the locking devices 9 in interaction with the control devices 12, so that a movement of the ejection devices 6 in the direction of the open position 4 of the movable furniture part 2 is blocked.
[0041] The locking device 9 can be unlocked via the ejection device 6 both by exerting pressure on the ejection device 6 in the closing direction 11 (corresponds to the closing direction 11 of the movable furniture part 2 in the use position) and by exerting tension on the ejection device 6 in the opening direction 7 (corresponds to the opening direction 7 of the movable furniture part 2 in the use position), so that the ejection device 6 can be triggered in the opening direction 7 in order to eject the movable furniture part 2 from the furniture body 19.
[0042] Fig. 2c shows the ejection devices 1 in a sectional view offset from Fig. 2b, wherein it can be seen that the ejection device 6 comprises a release device 13 in the form of a pivotable lever 14 which is subjected to force relative to the ejection device 6 for contacting and interacting with the locking device 9.
[0043] The release device 13 represents a component separate from the locking device 9 and the ejection device 6 for unlocking and / or locking the ejection device 6 via the locking device 9.
[0044] A particularly high triggering range of the ejection device 1 is connected to the release device 13, with a triggering safeguard being implemented in the locking mechanism due to the relative positioning (in particular the arrangement of the release device 13 on the ejection device 6) and the mobility of the component parts (in particular the guide track 15 for forming a push-through protection). This ensures high functionality and flexible use of the ejection device 1.
[0045] In connection with the ejection movement of the movable furniture part 2, the ejection devices 1 generate only a marginal noise despite the bidirectional unlockability and a possible asynchrony in the unlocking of the second locking device 9 during an opening movement of the movable furniture part 2 - generally mediated via an opening dynamic of the movable furniture part 2 - whereby a high level of operating comfort for a user of the movable furniture part 2 can be ensured.
[0046] The ejection device 6 is movable relative to the locking device 9 in the closing direction 11, wherein the locking device 9 can be unlocked exclusively by a movement of the ejection device 6 in the opening direction 7.
[0047] Fig. 2d shows, in the case of the right ejection device 1 (in contrast to the left ejection device 1), a pivoting position of the lever 14 relative to the locking device 9, in which an unlocking of the locking device 9 can be generated by pulling on the basis of the force storage device 8 (concealed by the lower region of the housing 5).
[0048] The release device 13 is provided for contacting and interacting with the locking device 9, wherein the release device 13 is arranged on the ejection device 6. Fig. 2e shows that the locking device 9 is pivotable for unlocking in order to release the control device 12 and the ejection device 6 via the lever 14.
[0049] The right ejection device 1 is already unlocked for ejection, whereas the left ejection device 1 is not yet activated.
[0050] In Fig. 2 f, the ejection movement has already progressed, whereby the ejection movement of the right ejection device 1 has also unlocked the left ejection device 1 via a force transmission from the lever 14 to the locking device 9.
[0051] The right ejection device 1 was unlocked by pushing and the left ejection device 1 was unlocked by pulling in order to release the respective ejection device 6 .
[0052] Fig. 2g shows the ejection devices 1, with the components located within the housing 5 - in particular the energy storage device 8 connected to an adjustment device - being visualized on the right.
[0053] Fig. 3a to 3f show the area relevant for unlocking the ejection device 1 in an enlarged view during the activation of the ejection device 6 in the course of an over-pressing movement (a pure pulling movement for releasing the ejection device 6 is also possible).
[0054] The release device 13 is pivotally mounted on the ejection device 1 and comprises a contact contour 35 as a contact surface, with which the locking device 9 can be contacted in two separate contact positions 37, 38. The contact contour 35 is curved in order to impart varying forces to the locking device 9 when the pivot position of the lever 14 changes, and has a ribbing 39 to ensure undesired slipping when the ejection device 6 is desired to be locked.
[0055] The ejection device 6, the energy storage device 8, the control device 12, the locking device 9 and the release device 13 are guided in guide tracks 15 of the housing 5.
[0056] The ejection device 6 is arranged partially outside and partially inside the housing 5, wherein the energy storage device 8, the control device 12, the locking device 9 and the release device 13 are arranged inside the housing 5.
[0057] The ejection device 1 s is designed without a synchronization shaft, wherein in general an interface 16 can be provided for connecting a synchronization shaft 17 for synchronizing the ejection device 1 with another ejection device 1 .
[0058] An exemplary method for ejecting the movable furniture part 2 from the closed position 3 towards the open position 4 relative to the furniture body 19 by two ejection devices 1 can be explained as follows:
[0059] - the first ejection device 6 of the first ejection device 1 of the two ejection devices 1 is moved by pressure on the movable furniture part 2 in the closing direction 11 from the closed position 3 into an overpressure position 22,
[0060] - the first energy storage device 8 of the first ejection device 1 moves the first ejection device 6 in the direction of the open position 4, so that the first locking device 9 of the first ejection device 1 is unlocked and the first ejection device 6 is moved in the opening direction 7,
[0061] - the movable furniture part 2 is moved by the first
[0062] Ejection device 6 is moved in the opening direction 7, so that the second ejection device 6 of the second ejection device 1 of the two ejection devices 1 is moved in the opening direction 7,
[0063] - the second locking device 9 of the second
[0064] Ejection device 1 is activated by pulling on the second
[0065] Ejection device 6 is unlocked in the opening direction 7 without a synchronization shaft, so that the second force storage device 8 of the second ejection device 1 transmits force to the second ejection device 6 and the movable furniture part 2 is subjected to force in the direction of the open position 4.
[0066] Thus, the first locking device 9 and the second locking device 9 can be unlocked asynchronously (or synchronously) from the respective locking position 10 (by pushing movement of one ejection device 6 and subsequent pulling movement of the second ejection device 6).
[0067] Fig. 4a, 6a and 8a show further preferred embodiments of an ejection device 1 in a perspective view.
[0068] Fig. 4b, 6b and 8b show that the ejection device 1 comprises the housing 5, the ejection device 6, the energy storage device 8, the control device 12 and the locking device 9.
[0069] The ejection device 1 comprises the release device 13, wherein the ejection device 6 comprises the release device 13 for contacting and interacting with the locking device 9, wherein the release device 13 is arranged on the ejection device 6.
[0070] In Fig. 5a, in an enlarged detail of the ejection device, it can be seen that the release device 13 is arranged directly on the ejection device 6, partially within the ejection device 6 and directly between the ejection device 6 and a housing side wall 30 of the housing 5.
[0071] The release device 13 comprises a damping device 31 in the form of a rotary damper (the specific design of the damping device 31 being irrelevant), with which a rotation of the release device 13 about a rotation axis 32 arranged on the ejection device 6 can be damped.
[0072] The damping device 31 forms a timing element for contacting the locking device 9 by the release device 13 and can be provided as push-through protection for the ejection device 6 of the ejection device 1 in conjunction with an overpressure position 22.
[0073] The damping device 31 is arranged directly on and in the ejection device 6.
[0074] Fig. 5b to 5f show different positions of the release device 13 in the form of the pivotable lever 14 which is acted upon by force relative to the ejection device 6.
[0075] The release device 13 is pivotally mounted on the ejection device 1 and has the contact contour 35 in the form of the contact surface - curved and having the corrugation 39 - with which the locking device 9 in two separate
[0076] Contact positions 37 , 38 can be contacted
[0077] The locking device 9 can be unlocked via the ejection device 6 by exerting pressure on the ejection device 6 in the closing direction 11 or by exerting tension on the ejection device 6 in the opening direction 7 in order to trigger the ejection device 6 in the opening direction and to ensure that the movable furniture part 2 is ejected from the furniture body 19.
[0078] Starting from Fig . 5a, the ejection device 6 in Fig . 5b was
[0079] Closing direction 11, so that the lever 14 contacts the locking device 9 in locking position 10. In Fig. 5c and 5d, the ejection device 6 has been moved into an overpressure position 22, wherein the lever 14 automatically pivots downwards about the rotation axis 32 by the application of force by the spring (and damped by the damping device 31).
[0080] 5e, the lever 14 is deflected in the guide track 15 during the over-pressing position 22 in such a way that when the ejection device 6 moves in the opening direction 7, the lever 14 contacts the locking device 9 via the contact contour 35 in such a way that the locking position 10 would be re-established. In contrast, in Fig. 5f, the lever 14 can pivot freely downwards in the guide track 15 during the over-pressing position 22 in a damped manner (this is generally not absolutely necessary), so that when the ejection device 6 moves in the opening direction 7, the lever 14 contacts the locking device 9 via the contact contour 35 in such a way that the locking device 9 is unlocked by sufficient force transmission to the locking device 9. According to Fig. 5e and 5f, a push-through protection is implemented in the ejection device 1.If the movable furniture part 2 is moved at high speed in the closing direction 11, the lever 14 is moved via a guide pin into the upper section of the guide track 15 in the illustration - the push-through track of the.
[0081] Overpressure position 22 - maneuvered so that subsequent
[0082] Movement of the ejection device 6 in the opening direction 7 of the lever 14 - by application of force via a spring connected to the ejection device 6 and via the damping device 31 - the locking device 9 contacts at a first contact point 37 in order to set a locking position 10 and to prevent undesired ejection. If ejection of the movable furniture part 2 from the locking position 10 is desired, the lever 14 is moved from the locking position 10 into the lower section of the guide track 15 in the illustration - the unlocking track of the overpressure position 22 - wherein the lever 14 has sufficient time to
[0083] Locking device 9 in a second contact point 38. At the second contact point 38, a force ratio exists which is sufficient for unlocking the locking device 9 and thus for releasing the ejection device 6.
[0084] An exemplary method for operating the ejection device 1 can be explained as follows:
[0085] - the ejection device 6 is moved from the open position 4 together with the control device 12 and the release device 13 into the closed position 3
[0086] - the ejection device 6 is moved together with the release device 13 from the closed position 3 into an over-pressing position 22 - the ejection device 6 is moved back together with the release device 13 from the over-pressing position 22 in the direction of the closed position 3, wherein the release device 13 is pivoted in a damped direction orthogonal to the opening direction 7, so that the release device 13 contacts the locking device 9 in the closed position 3 and a movement of the ejection device 6 together with the control device 12 and the release device 13 by the locking device 9 in the locking position 10 in the direction of the open position 4 is inhibited.
[0087] The locking position 10 can be released by pulling on the ejection device 6 or by pushing the ejection device 6 over.
[0088] Fig. 7a to 7e and Fig. 9a to 9d as well as Fig. 10a to 10e illustrate the kinematic interaction of the components involved in locking and unlocking the ejection device 1 in alternative structural designs and analogous locking and unlocking mechanisms for the function of the ejection device 1. For example, the locking device 9 can be designed as a pivotable unlocking lever or as an incline of the guide track 15. For example, a reset of the energy storage device 8 can be provided via a linear trigger slide, a rotatably mounted reset device acted upon by a leaf spring or a combination.
[0089] Fig. 11 shows a piece of furniture 18 with three movable furniture parts 2 that can be displaced relative to the furniture body 19, wherein one movable furniture part 2 has been dismantled to expose the ejection device 1. A second, mirror-symmetrical ejection device 1 is arranged on the furniture body 2 opposite the visible ejection device.
[0090] This embodiment of the ejection device 1 also comprises the housing 5, the ejection device 6, the energy storage device 8, the control device 12 and the locking device 9 as well as the release device 13.
[0091] The ejection device 1 can be connected modularly to a guide system for the movable furniture part and / or retrofitted to the guide system as an add-on.
[0092] Fig. 12a shows that the ejection device 1 comprises the release device 13 for directly contacting the locking device 9, although indirect contact is generally also conceivable.
[0093] The release device 13 is pivotally arranged on the ejection device 1 and comprises the contact contour 35, with which the locking device 9 can be contacted in two separate contact positions 37, 38 for maintaining the locking position 10 or for unlocking the locking device 9.
[0094] The contact contour 35 is curved and has prongs in the form of a corrugation 39 , wherein the release device 13 in the form of the pivotable and force-loaded lever 14 is fastened directly to the ejection device 6 .
[0095] As with the other embodiments of the ejection device 1, a damping device 31 is generally provided for the release device 13, which acts as a timing element for the lever 14 and the ejection device 1 can be unlocked by pulling and pushing without the mandatory requirement of a synchronization shaft 17.
[0096] In this embodiment, an arrangement of two ejection devices 1 and a synchronization shaft 17 is provided for synchronizing the two ejection devices 6 of the two ejection devices 1.
[0097] The two release devices 13 of the two ejection devices 1 can be contacted by the contact contours 35 (indirectly coupled via the synchronization shaft 17) at different contact positions 37, 38 with the two locking devices 9 of the two ejection devices 1, wherein before unlocking both locking devices 9 are in a first contact position 37 - representing the locking position 10.
[0098] In Fig. 12b, the right ejection device 6 is moved into the overpressure position 22, wherein the left ejection device 6 remains in the starting position. This can be the case, for example, if one-sided pressure was exerted on the movable furniture part 2. Without the synchronization shaft 17, the left ejection device 1 could be triggered indirectly via the movable furniture part 2 if the right ejection device 1 is already unlocked and has been moved further in the opening direction 7, so that the left ejection device 6 is pulled along. In this embodiment, a synchronous unlocking is initiated, since when the right locking device 9 is unlocked by the synchronization shaft 17, the left locking device 9 is also unlocked.
[0099] This situation is illustrated in Fig. 12c, wherein in the right-hand ejection device 1, the lever 14 is connected to the locking device 9 via a second contact position 38, whereas the left-hand lever 14 remains in the first contact position 37. Due to the shape or geometry of the lever 14 in interaction with the locking device 9, the second contact position 38 is suitable for causing an unlocking.
[0100] Fig. 12d and 12e show the transition of both locking devices 9 into the unlocked state to release the two ejection devices 6 or the associated control devices 12, wherein the ejection devices 6 are unlocked in the same direction in the opening direction 7 by the synchronization shaft 17.
[0101] In principle, the two ejection devices 6 can be unlocked both by pulling (in the opening direction 7) and by pushing (in the closing direction 11). A specific position of the lever 14 can be used to unlock and synchronize the ejection devices 1.
[0102] Fig. 12 f shows the state of the two ejection devices 1 after completion of the synchronization of the unlocking of the two locking devices 9, wherein an exemplary method for synchronizing the two ejection devices 1 can be explained as follows:
[0103] - the release devices 13 of the first and second ejection device 1 are moved into a closed position 3, wherein the at least two release devices 13 contact the two locking devices 9 in the same contact position 37
[0104] - the release device 13 of the first ejection device 1 is moved from the closed position 3 into the overpressure position 22 and from the overpressure position 22 back into the closed position 3, wherein the release device 13 of the first ejection device 1 contacts the locking device 9 of the first ejection device 1 at a contact position 38 which is separate and modified from the first contact position 37, so that the locking device 9 is used to activate the ejection device 6 of the first
[0105] Ejection device 1 is pivoted
[0106] - the synchronization shaft transmits the pivoting movement of the locking device 9 of the first ejection device 1 to the locking device 9 of the second ejection device 1, wherein the locking device 9 of the second
[0107] Ejection device 1 is pivoted and the ejection device 6 of the second ejection device 1 is released.
