    The invention relates to a drive device for a movable furniture part, comprising an ejection element for moving the movable furniture part from a closing pitch to an open position, the ejection element kraftbeaufschlagenden ejection force memory and a locking device for locking the ejection element via a locking element in a locking portion, wherein by overpressing the movable furniture part the closed position in the closing direction in an overpressure position, the locking device can be unlocked, whereby the movable furniture part is movable in the opening direction by the ejection force accumulator and the ejection element. In addition, the invention relates to a piece of furniture with a furniture body, a movable furniture part relative to the furniture part and a drive device according to the invention for the movable furniture part.
    In the furniture sawing industry, drive devices have already been known for many years with which, by pressing on the movable furniture part (eg a drawer), an unlocking takes place from the furniture carcass and subsequently the movable furniture part is opened or ejected. Such Antriebsvorriehtungen have a so-called touch-latch mechanism. In this mechanism, the movement for closing the drawer from the open position and the movement for unlocking or opening the drawer from the closed position in the same direction, namely in the closing direction. In a normal gentle closing (dog or by a retractor), the drawer or the movable furniture part is held by the locking device in the closed position. But if a too strong pressing or pushing the drawer up to the end stop, the ejection device can not lock or is immediately triggered again and placed in the overpressure, whereby no safe closing is guaranteed in such a malfunction of the movable furniture part.
    To solve this problem is from the priority older but not previously published Austrian patent application A 52/2012 a 2/31 73300 22 / gb

    Blocking element known to prevent the movement in the overpressure position at too fast closing movement.
    The object of the present invention is to provide an alternative possibility to prevent immediate triggering or unlocking of the ejection device even in case of incorrect operation by pushing the movable furniture part.
    This is achieved by a drive device according to claim 1. Accordingly, it is provided that the locking device has a pre-locking portion for the locking element, wherein the locking element passes from the pre-locking section via a push-through avoidance in the locking section by pushing the movable furniture part when closing in a lying in the closing direction behind the closed position push-through. Thus, the locking element does not enter immediately upon locking in the locking portion but is held in the Vorverriegelungsabschnitt, which has its own push-through avoidance portion, from which the locking element can not be directly ejected, but first passes into the actual locking portion. To make this possible, the locking portion should be different from the pre-locking portion. In particular, the locking portion should be spaced from the pre-locking portion in the opening direction of the movable furniture part vörieinärider. In other words, the pre-locking portion lies in the closing direction behind the locking portion.
    By itself, such a push-through protection may be useful in various embodiments of touch-latch mechanisms, such as those mechanisms that work on the ballpoint pen principle. Preferably, however, it is provided that the Verriegeiungsvorrichtung has a, preferably heart-shaped, guideway for, preferably peg-shaped, locking element, said Verriegeiungselement in the locking portion in a, preferably trough-shaped, latching area 3/31 • fr »fr fr ··· 'fr * · Fr «· * · fr · fr fr · · · · > The guideway, preferably a heart-shaped guideway, is arranged in this way is durable or lockable t. In the embodiment of the locking device with such a heart-shaped guide track is preferably provided that the guide track successively a, preferably straight, clamping portion, a preferably curved deflection portion, the pre-locking portion, the locking portion in the form of a trough-shaped detent area (detent recess), a rejection - Has or Entriegelungsschräge and an ejection section. In order to enable the normal ejection or unlocking is further preferably provided that the guideway between the Entriegelungs- or Abweisschräge and the ejection section has a second, separate from the push-through evasion section escape section for the locking element.
    According to a particularly preferred embodiment of the present invention it is provided that in the pre-locking portion, a holding element for the 'locking element is arranged or formed.
    According to a first embodiment variant for this holding element, it can be provided that the guideway has a straight abutment surface for the locking element in the front Verriegeiungsabschnitt as a holding element. This straight abutment surface is aligned so that the force acting on the locking element from the ejection force holds the locking element on this abutment surface. Preferably, the forces act substantially normal on this straight contact surface.
    As a second embodiment of this holding element can be provided that the Haiteelement in the form of a movable damping element, preferably in the form of a rotary damper, is formed. Instead of a rotary damper, of course, a translationally movable damper piston or the like can be used. Preferably, it is provided for this damping element, that the damping element has a damped rotatably mounted gear, wherein at least one tooth of the gear in the pre-4/31
    Locking portion of Verriegeiungselement contactable and attenuated in the direction of locking portion is movable. Thus, with this damping element, the locking element is not held statically in the pre-locking section, but slowly moved in the direction of the locking section. If, therefore, during this time, where the locking element is still in abutment with the damping element, a push-through, the locking element initially differs in the push-through avoidance, instead of directly pass through the Abweisungs- or Entriegelungsschräge in the ejection section.
    As is known per se, it is further provided that the ejection force memory can be loaded by moving the movable furniture part in the opening direction and / or in the closing direction. Favor is also provided for this invention, that only after complete loading of the ejection force accumulator, the ejection element can be locked via the locking element in the pre-locking section. That is, the ejection force accumulator is fully tensioned when locked over the locking member in the pre-locking portion.
    Preferably, the drive device has a retraction device for retracting the movable furniture part from an open position to the closed position, wherein - when the locking element reaches the pre-locking section - the movable furniture part is in an open position and from this open position, the movable furniture part by the retractor in the Closed position is movable.
    Especially when the holding element is designed as a straight abutment surface, it is preferably provided for the movement of the locking element in the locking portion that only when moving the movable furniture part by the retraction device in the closed position, the locking element from the pre-locking portion is movable into the locking portion. It is particularly advantageous if the locking element is movable in dependence of the retraction of the pre-locking portion in the locking portion.
    Protection is also sought for a piece of furniture with the features of claim 16. In principle, the output device may be arranged on the furniture body and eject the movable furniture part via the ejection element. Preferably, however, it is provided that the drive device is arranged on the movable furniture and arranged with the ejection element engageable driver on the furniture body. Thus, the drawer pushes over the drive device, so to speak, even from the furniture body.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings.

    In Fig. 1, a furniture 14 with a furniture body 15 and a total of four movable furniture parts 2 is shown in general. Each furniture part 2 consists of at least one thrust receptacle 17 and a front panel 18. The movable furniture parts 2 are attached via a pull-out 21, consisting of a drawer rail 19, a carcass rail 20 and optionally a center rail, not shown, on the furniture body 15. In the uppermost drawer, it can be seen that the drive device 1 together with the ejection element 3, the locking element 6 which is movable in the guide track 7 and the ejection force accumulator 4 is fastened or arranged on the movable furniture part 2 or on its drawer rail 19. The 6/31 •. ····································································································································································· •···························································· · · · · · · · · · · ** ** **
    Locking device 5 is formed by the guide track 7 and the locking element 6. On the carcass rail 20 or the furniture body 15 itself, a driver 16 is arranged, with which the ejection element 3 is at least partially engaged. This top drawer is in the open position OS. If the drawer of this open position OS is moved further in shooting direction SR, then the locking element 6 enters the pre-locking portion VV of the guideway 7 (see in detail the later described Fig. 5). In this position (second drawer from the same level) the ejection force accumulator 4 is fully tensioned and the movable furniture part 2 can then be moved into the closing pitch SS (third drawer from above) by the retraction device 13, which is shown only schematically and integrated into the pull-out guide 21 In the case of a normal unlocking and opening operation, the movable furniture part 2 reaches the overpressure position ÜS (lowermost drawer in Fig. 1) in relation to the movable furniture part 2. This overpressure position also corresponds exactly to the pressure setting position DS in the drive device 1 itself In this case, however, the locking element 6 is in different sections (push-through escape section D or second escape section W) .After the normal overpressures in the closing direction SR, the movable furniture part 2 is ejected by the drive device 1 in the opening direction OR.
    Fig. 2 shows an exploded view of the essential components of a first embodiment of the drive device 1. This drive device 1 is mounted on the base plate 23 on the movable furniture part 2 and on the drawer rail 19. At this base plate 23, in turn, the cover 22 is mounted. In the base plate 23, the guide track 7 is formed with the tension portion S, the deflection portion L, the pre-locking portion W, the push-through avoidance portion D, the lock portion V, the deflection and unlocking slope E, the second escape portion W, and the discharge portion A. The position of this base plate 23 in the closed position SS relative to the furniture body 15 can be adjusted via the depth adjustment wheel 24. The ejection element 3 is relative to the 7/31 ····························································································· ♦ ··· · · · · ♦ · · · ♦ · · i · '* 7 ........ *
    Cover 22 and the base plate 23 movably mounted. The ejection force accumulator 4 is held on the one hand via the spring base 25 on the base plate 23 and on the other hand via the spring base 26 on the ejection element 3. This ejection energy storage 4 is designed as a tension spring. At the ejection element 3 is the pivot bearing 27, on which the locking lever 28 is rotatably supported via the rotation axis X. At the front end of the locking lever 28, the pin-shaped and engaging in the guide track 7 locking element 6 is arranged. Sectionally connected to the ejection element 3 is the Einziehschlitten 30, on which the catching arm 29 is rotatably mounted. In addition, this Einziehschlitten 30, the latching stopper 35 and the stopper 32, while the locking lever 28 of the projection 34 and the pivot stop 33 is formed.
    In Fig. 3, the drive device 1 is shown when the movable furniture part 2 is in an open position OS. In this case, the tentacle 29 is pivoted into its release position. The ejection force memory 4 is relaxed. The locking element 6 is in its initial position at the beginning of the clamping section S of the guideway. 7
    Now, if the movable furniture part 2 together with the drive device 1 in, as shown in Fig. 4, is moved in the closing direction SR, the body-fixed driver 16 comes into abutment with the Einziehelement 30 and moves the Einziehschlitten 30 coupled ejection element 3 relative to the cover 23rd in which the locking element 6 moves along the tensioning section S and at the same time the ejection force accumulator 4 fastened to the ejection element 3 is tensioned. During this closing movement, the catch 16 is held or caught in the catching area 31 between the catching arm 29 located in the catching position and the pulling-in carriage 30.
    This, normally dog-shaped closing movement is continued until the position according to FIG. 5 (still an open position OS) is reached. As a result of the fact that the locking element 6 moves in the direction of the pre-locking section W due to the curved configuration of the deflection section L, the entire locking lever 28 also pivots counterclockwise about the rotation axis X, as a result of which the stop 32 of the Einziehschlittens 30 out of engagement with the locking lever 28 formed on the projection 34 passes, which in turn results in that the ejection element 3 is decoupled from the Einziehschlitten 30 and thus from the manual exercise of force. As soon as this decoupling has taken place, the force of the now completely stretched ejection force accumulator 4 acts directly on the locking element 6. Since this locking element 6 is located precisely in the pre-locking section W at this moment, this force of the ejection force accumulator 4 acts essentially normal on the retaining element 9 forming straight abutment surface F of the guideway 7. Thus, in this position shown in FIG. 5, the ejection element 3 is locked in the pre-locking section W (see in detail Fig. 5a). Furthermore, it can be seen in detail from FIG. 5 b that the pivoting stop 33 still protrudes by the angle α.
    Subsequently, then in Fig. 6 only schematically shown
    Pulling device 13 move the movable furniture part 2 together with the drive device 1 in the closing direction SR. As soon as during this movement the Einrastansehlag 35 formed on the Einziehschlitten 30 abuts the pivot stop 33 of the locking lever 28 (see Fig. 6b), the locking lever 28 pivots further counterclockwise about the rotation axis X, whereby the locking element 6 from the pre-locking section W moves and moves in the direction of the locking portion V forming trough-shaped latching area 8 (see Fig. 6a).
    With this release of Verriegeiungselements 6 from the pre-locking section W, the retracting device 13 has done so to speak their last "work", after which the locking element 6 passes as shown in FIG. 7 by a slight relaxation of the ejection force memory 4 in the Verriegetungsabschnitt V. Thus, the movable furniture part 2 is in the closed position SS. According to FIG. 7a, the pivot stop 33 is again lifted slightly away from the catch stop 35 by this slight relaxation movement of the ejection force accumulator 4. 9/31 ·: · ···· •: · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · ····························································································································································
    According to FIGS. 3 to 7, a normal closing movement sequence without incorrect operation is described. If, however, the manual closing movement does not cease as soon as the ejection force accumulator 4 is tensioned, but the movable furniture part 2 is pressed even further into the closed position SS and beyond into the push-through position DS according to FIG. 8, the locking element 6 is pushed by the pre-locking section W in FIG the push-through avoidance D moves until the Einziehschlitten 30 abuts the end 37 of its guide rail 36 in the cover 23 or until the front panel 18 abuts the furniture body 15.
    If then the faulty operation was finally noticed or the movable furniture part 2 is released due to the wrong way completely manually performed closing process, the locking element 6 passes due to the relaxation of the ejection force memory 4 from push-through D section in the locking portion V and the Sehließstellung SS shown in FIG 9 is reached. This position according to FIG. 9 again corresponds to the position according to FIG. 7.
    Starting from this closed position SS, the locking device 5 can then be unlocked at any time by a user by overriding the movable furniture part 2 in the closing direction SR. As is known per se, the locking element 6 passes via the deflection and unlocking slope E into the second escape section W (see FIG. 10), as a result of which the overpressure position ÜS according to FIG. 10 is reached
    Once then the manual unlocking movement is completed, the ejection force accumulator 4 pulls the ejection element 3 relative to the cover 23 and the base plate 22, whereby the movable furniture part 2 is ejected or attached to the movable furniture part 2 drive device 1 repels the body-fixed driver 16. In this case, the locking element 6 moves along the ejection section A of the guide track 7 and the movable furniture part 2 enters the open position OS shown in FIG. 11. 10/31 ··············· φ φ φ φ φ φ φ φ φ φ • · · · ····· φφ
    Upon further opening movement of the Einziehschlitten 30 is again coupled to the ejection element 3, wherein the locking lever 28 is pivoted and the locking element 6 is moved back toward the starting position. At the same time, as shown in FIG. 12, the carrier 16 is released again by the pivoting of the catching arm 29.
    In Fig. 13, the locking element 6 is again in its initial position, the tentacle 29 is again completely open and located in the open position OS movable furniture part 2 is independent of the driver 16 freely movable.
    As an alternative to the holding element 9 designed as a straight abutment surface F, it is shown in FIG. 14 that the holding element 9 is designed as a damping element 10 and, in concrete terms, as a toothed wheel 11. As soon as the locking element 6 has reached the position according to FIG. 14a, it is moved by the ejection force accumulator 4 or by a corresponding deflection in the direction of the locking section V. When the locking element 6 rests against the tooth 12 projecting into the pre-locking section W, the movement of the locking element 6 triggered by the ejection force accumulator 4 is damped, in which the toothed wheel 11 rotatably mounted in a viscous mass moves only very slowly counterclockwise. As soon as the toothed wheel 11 has moved by approximately 30 degrees, the locking element 6 no longer contacts the tooth 12 and reaches the locking section V according to FIG. 15, as a result of which the movable furniture part 2 is in the closed position SS. Due to the fact that the locking element 6, depending on the duration of the rotational movement of the damping element 10, is relatively long in the pre-locking section W, when the movable furniture part 2 is pushed through (incorrect operation), the locking element can move into the push-through avoidance section D and from there arrive after the end of the wrong operation in the actual locking section V. 11/31 ································································································· • * ♦ · · · · # ··· ··· «··« · · ·· 11
    Thus, an improved Druchdrückschutz is created by the present invention by the locking element 6 is not immediately locked in the locking portion V, but is locked before reaching the closed position SS of the movable furniture part 2 in a pre-locking section W, so that when you press the push-through Dodge section D for the locking element 6 is available.
