专利说明:
The invention relates to a drive device for a movable furniture part, comprising a tensionable ejection energy storage, a ejection force kraftbeaufschlagten ejection element for performing an ejection movement of the movable furniture part from a closed position to an open position, wherein by an override of the movable furniture part in a behind the closed position Überdrückstellung the ejection movement can be introduced and a clamping device for clamping the ejection force accumulator with a deliverable during the ejection energy. Furthermore, the invention relates to a piece of furniture with a furniture body, a movable furniture part and such a drive device. In the furniture fitting industry, there have been many kinds of drive devices for many years to allow a simple ejection of a movable furniture part (such as a drawer or a furniture door) from a closed position. As a result, a user no longer has to pull on the movable furniture part to open it, but can activate or initiate the ejection or opening by a simple release movement (for example, over-pushing the movable furniture part). One problem with mechanical drive devices is usually how and where the ejection force accumulator is tensioned. In the simplest variants, an ejection force accumulator in the last closing movement range is tensioned before reaching the closed position (for example, according to the ballpoint pen principle). During ejection, the active ejection then takes place along the same movement range in the opening direction. But there are also other drive devices in which the ejection energy storage when opening or closing further outside (not in the last closing or opening area) is stretched. An example of this is given in AT 008 629 U1. A similar device is also apparent from DE 198 23 305 A1. Now it is in many known drive devices so that, depending on the strength of the ejection force accumulator or depending on the weight of the movable furniture part, the clamping movement is distracting. That is, there is no continuous uniform opening or closing movement, since at least on a part of the opening and / or closing path, the clamping of the ejection force accumulator must be done. In this area, therefore, the movement of the movable furniture part is less easily common. The object of the present invention is therefore to provide a comparison with the prior art improved drive device. In particular, the drive device should be designed such that a largely common and uniform movement of the movable furniture part between the open position and the closed position is given. This is achieved by a drive device having the features of claim 1. Accordingly, it is provided according to the invention that at least 50% of the energy released during the ejection movement by the ejection energy store can be introduced into the ejection force accumulator during the overpressure movement by the tensioning device. In other words, this means that the majority of the charging energy for the ejection energy storage is introduced into the ejection force accumulator only in the overpressure movement. In previous versions, it is true that usually far more than 90% of the charging energy is introduced somewhere in the region of the opening or closing movement. A small negligible part of the charging energy has hitherto sometimes been introduced during the overpressing movement, since so-called touch-latch mechanisms also had to be pressed against the ejection force accumulator during the overpressure movement in various variants (see, for example, WO 2011/143682 A1). Thus, a much smoother movement sequence of the movable furniture part is guaranteed, since not the entire part of the charging energy for the ejection energy storage must be introduced before reaching the closed position. It is preferably provided that during the pushing-over movement by the clamping device at least 80% of the ejection movement of the Eject energy stored energy can be introduced into the ejection energy storage. In particular, it is of great advantage if, in the pushing-over movement by the tensioning device, almost 100% of the energy released by the ejection force accumulator during the ejection movement can be introduced into the ejection force accumulator. This means that the clamping of the ejection force accumulator takes place only after reaching the closed position, ie between the closed position and the overpressure position. In other words, the clamping of the ejection force accumulator takes place only in the region of the overpressure movement of the furniture part path. According to a further aspect, the present invention relates to a generic drive device, wherein from the movable furniture part during clamping of the ejection force accumulator on the clamping device a furniture part clamping path is zurücklegbar, in which the ejection force memory from a relaxed or partially tensioned position along a power storage-tensioning movable in a cocked position is, and wherein the movable furniture part when ejecting the movable furniture part on the ejection element a furniture part discharge path is zurücklegbar, in which the ejection force memory from the said tensioned position along a force accumulation-Entspannweg in said relaxed or partially clamped position is movable. Another problem that often occurs in the prior art is that loading of the ejection force accumulator must occur over a relatively long furniture part travel path upon opening and / or closing. Thus, a user must perform this clamping movement for a relatively long time. Another object of the present invention is therefore to improve such drive devices or to provide an alternative clamping possibility. This is achieved in that the furniture part discharge path is greater than the furniture part clamping path. That is, only a relatively small furniture moving path (furniture moving path) is used to have a larger furniture moving path (furniture moving path) for the ejecting movement after overpressing. Particularly preferably, it is provided that the furniture part clamping path largely corresponds to the furniture part movement path during the pushing-over movement. In other words, it can thus be provided that in the overpressure movement by the tensioning device almost 100% of the output in the ejection movement of the ejection energy storage energy in the ejection force memory can be introduced. Especially if the furniture part clamping path substantially corresponds exactly to the overpressure, this has the advantage that the user does not notice the tensioning during the normal Möbelteilbewegungsweg at all, since it takes place only when overpressure. In order to obtain the shortest possible furniture part clamping path, it is preferably provided that the furniture part discharge path is at least twice, preferably at least four times, as large as the furniture part clamping path. Loading the ejection force accumulator and unloading the ejection force accumulator does not have to be done with a linear energy output or a linear energy input. Rather, here also curves or different steep loading or unloading, depending on the nature and design of the spring or the energy storage device can be provided. Preferably, this is suitably provided that the, preferably averaged over the furniture part-tensioning ratio of power storage tensioning path to furniture part clamping path in the overpressure is greater than that, preferably averaged over the furniture part discharge path, ratio of energy storage expander to Möbelteil- Discharge path in the ejection movement. For the implementation of the present invention, there are different concrete embodiments. In the following two variants are explained in detail: According to the first embodiment variant, the drive device has a transmission device which is arranged between a tensioning element of the tensioning device and the ejection element. It is preferably provided that the translation between the clamping element and the Ejecting energy storage when clamping the ejection force accumulator is different than between the ejection element and the ejection energy storage when ejecting the movable furniture part. That is, in a shorter way (furniture part-tensioning path) via the transmission device, the same energy is introduced, which is then delivered in a longer way (furniture part discharge path). In this case, it is preferably provided that the clamping element and the ejection element are formed separately. According to a specific embodiment of this first embodiment, it is preferably provided that the clamping device comprises a housing, an axle bolt connected to the housing, a clamping disk rotatably mounted on the axle pin with locking elements, the tensioning element eccentrically connected to the clamping element, a rotatably mounted on the axle pin gear with locking stops for the locking elements and the ejection force accumulator, which is held with a first spring base on the tensioning pulley and with a second spring base on the housing has. For a simple clamping is preferably provided that during the overpressing the clamping disk is rotatable by the clamping element relative to the transmission pulley, whereby the ejection force accumulator passes from said relaxed or partially tensioned position in said tensioned position, wherein in said tensioned position the clamping disc on at least one of the locking elements is latched to a latching stop of the transmission disc. Since the clamping element is formed separately from, preferably movably mounted on the housing, ejection element in this first embodiment, it is preferably provided that on the ejection element, a lever is movably mounted via one end and the lever is connected eccentrically and movably at the other end with a gear, wherein the gear meshes with arranged on the gear teeth. Thus, the ejection element can be actuated via the translation disc. These components together with the Clamping disc, the ejection energy storage and the transmission disc, the Übe rsetzungsvo rrichtu n g. In contrast to the first embodiment, in the second embodiment, no translation is carried out on the basis of a gear ratio. Rather, in the second embodiment, the ejection force accumulator has a first spring base and a second spring base, both spring bases are movable relative to a housing of the drive device during tensioning of the ejection force accumulator, and when ejecting the first spring base is stuck relative to the housing, and the second spring base is movable relative to the housing. As a result, when tightening by moving both spring bases, a smaller furniture part movement path can be used to introduce the same energy, which is then used in a larger (unidirectional) furniture movement path for the ejection movement. This is particularly preferably improved in that the tensioning device has a first and a second movable, preferably rotatably mounted on the housing, clamping element, wherein the first spring base of the ejection force accumulator on the first clamping element and the second spring base of the ejection force accumulator is held on the second clamping element. In this embodiment, it is advantageous in contrast to the first embodiment, when the second clamping element forms the ejection element. Thus, fewer parts are necessary. Furthermore, it is preferably provided that during the pushing-over movement, the first clamping element and the second clamping element are movable relative to each other and relative to the housing, whereby the ejection force accumulator passes from said relaxed or partially tensioned position into said tensioned position. In order to guarantee the movement of only one spring base, it is preferably provided that during the ejection movement of one of the clamping elements, preferably the first clamping element, is held at least a major part of the ejection movement via a holding device on the housing. Protection is also sought for a piece of furniture with a furniture body, a movable furniture part and a drive device according to the invention for the movable furniture part. 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. Show: 1 is a view of a piece of furniture with a drive device, Fig. 2 shows the Möbelteilbewegungsweg in comparison with the energy of Ejection force accumulator in the prior art, Fig. 3 shows the Möbelteilbewegungsweg in comparison with the energy of Ejection force accumulator in a drive device according to the invention, 4 is an exploded view of a first embodiment of the Driving device 5a-12 the movement of a drive device according to the first embodiment, Fig. 13 is an exploded view of a drive device according to the second Variant, Fig. 14 shows the drive device according to the second embodiment in the assembled state and Fig. 15-21 the movement of the second embodiment of the drive device. Fig. 1 shows a furniture 20, which has a furniture body 21 and a movable furniture part 2 in the form of a furniture door. This movable furniture part 2 is in the open position OS. The movable furniture part 2 is movably supported by two hinges 22 on the furniture body 21. These hinges 22 are configured in such a way that in the last section of the closing movement S running in the closing direction SR, the movable furniture part 2 is actively pulled into the closed position SS. The hinges 22 may also have a damping device for damped retraction of the movable furniture part 2. On the furniture body 21, a drive device 1 in the form of an ejection device via a housing 8 and a Montageplätte is also attached. The drive device 1 has in this first embodiment, a clamping element 6 and a separately formed by the clamping element 6 ejection element 4. FIG. 2 schematically shows the furniture moving path M as compared with the (charging) energy E of the ejecting force memory 3 in a prior art driving device. Horizontal, the entire Möbelteilbewegungsweg M is shown, which is composed of the running in the closing direction SR closing movement S and running in the opening direction OR opening movement O. During the closing movement S, the movable furniture part 2 first moves from the second open position OS2 in a freewheel to the first open position OS1. During this movement section no tensioning of the ejection force accumulator 3 occurs, which is why it remains in a relaxed position E0 (the subscript number after the "E" always corresponds approximately to the percentage charge of the ejection force accumulator 3 with energy E). This is indicated by the fact that the charging energy E of the ejection force accumulator increases from the first open position OS1 until it is finally fully charged in the overpressure position ÜS of the movable furniture part 2. That is, the ejection force memory 3 is located in the cocked position E10o- Between this relaxed position Eo and the tensioned position E100 is the energy storage clamping path Ks. In principle, it is also possible that this energy storage clamping path Ks is also further out, as indicated by the dashed line shown on the left side. This can be provided especially when a separate retraction device is provided for pulling the furniture part in a closed position SS. As is further apparent from FIG. 2, the force accumulator-tensioning path Ks of the ejection force accumulator 3 is covered by the fact that is actively pressed by a user on the movable furniture part 2 in the closing direction SR. This active furniture part movement path M corresponds to the furniture part tensioning path Ms, which extends between the first open position OS1 and the overpressure position ÜS. As can also be seen from FIG. 2, when the closed position SS is reached, the ejection energy accumulator is only approximately 80% charged. At concrete In the closed position SS of the ejection energy accumulator 3, design variants are usually already much more charged than in this schematic representation. As soon as the overpressure movement Ü is completed and the user no longer presses the movable furniture part 2 in the closing direction SR, the ejection movement A begins by discharging the ejection force accumulator 3. This ejection movement A is equivalent to the Möbelteilausstoßweg Ma, in which the ejection force memory 3 moves between the tensioned position E100 along the energy storage-Entspannweg KE to the relaxed position E0. As a result, the first open position OS1 is reached again. Thereafter, the movable furniture part 2 can be moved in a freewheel to the complete second open position OS2. A disadvantage of this known movement sequence according to the prior art is that a user in a large part of the furniture part movement M (in the concrete case in the closing movement S) does not experience a constant movement of the movable furniture part 2, since in the field of energy storage clamping path Ks from the the first open position OS1 active, a greater force must be applied to the movable furniture part 2, as is the case with a freely movable movable furniture part 2. Therefore, the great advantage of the present invention is illustrated in Fig. 3, according to which the energy storage clamping path Ks only begins when the closed position SS of the movable furniture part 2 is reached or after which the majority of the charging energy E is introduced into the ejection force memory 3 only when the closed position SS of the movable furniture part 2 is reached. Accordingly, in Fig. 3, the furniture part-tensioning Ms is much shorter. Specifically, this furniture part clamping path Ms corresponds to the overpressure Ü. Thus, during the overpressure movement Ü, the full energy E is introduced into the ejection force accumulator 3 in a relatively short region of the furniture motion path M, by the ejection force accumulator 3 from the relaxed position E0 (corresponding to the closed position SS) along the energy accumulator clamping path Ks to the cocked position Ei0o passes, which corresponds to the Überdrückstellung ÜS of the movable furniture part 2. As soon as in this overpressure position ÜS a user no longer presses on the movable furniture part 2, the ejection movement A is similar or the same as in previously known drive devices. That is, this ejection movement A corresponds to the furniture part discharge path Ma, which is much larger than the furniture part clamping path Ms- Once the first open position OS1 is reached, then the movable furniture part 2 can be moved in a freewheel to the full open position OS2 , In Fig. 3, the charging energy E of the ejection force memory 3 is indicated by the solid line. In this case, this line is idealized. Of course, there may be deviations here. Above all, the charging energy E can also increase progressively or not linearly. There may also be different steep sections both when stretching and when relaxing. This FIG. 3 is intended to schematically illustrate the averaged course between the relaxed position E0 and the tensioned position E10o. In Fig. 3 but in addition to the basic explanation of the ideas of the invention also slightly modified variants are indicated by the dash-dotted lines. The right-hand dot-dash line corresponds to the first concrete embodiment of the drive device 1. It is such that the ejection energy storage 3 at the end of the ejection movement A in said relaxed or partially tensioned position E0-5o, in which the ejection energy storage 3 is still partially stretched and Residual energy It includes, whereby by this residual energy Er of the ejection force accumulator 3, the ejection element 4 is movable after returning an ejection element ejection path Aa via an ejection element return path Ar in the closing direction SR. Thus, only a part of the (charge) energy E introduced in the furniture section Ms is also used as (ejection) energy for ejecting. The residual energy He is used in concrete for moving the ejection element 4 back to a starting position. The left-hand dash-dotted line corresponds to the second concrete embodiment of the drive device 1. It is such that the ejection force memory 3 is in the closed position SS of the movable furniture part 2 in said relaxed or partially tensioned position E0-5o, the ejection force memory 3 upon reaching the Closed position SS is already partially stretched by a closing movement S of the movable furniture part 2. This means that the clamping of the ejection force accumulator 3 already begins before reaching the closed position SS. However, the majority, namely more than 50% of the charging energy E, is introduced into the ejection energy accumulator 3 only between the closed position SS and the overpressure division ÜS. For the comparison between furniture part clamping path Ms and Möbelteilausstoßweg Ma but it is necessary in both embodiments, the same relaxed or partially tensioned position E0-so the energy storage clamping path Ks to compare with the same relaxed or partially tensioned position E0-5o of the energy storage-Entspannwegs Ke. From this it can always be deduced that the furniture part clamping path Ms is smaller than the furniture part discharge path M In addition, it can be seen from FIG. 3 that the ratio Ks: Ms of the force-storing tensioning path Ks to the furniture part tensioning path Ms in the overpressure movement Ü is approximately 9: 1. On the other hand, the ratio Ke: Ma of the energy storage expansion path Ke to the furniture discharge path Ma in the discharge movement A is about 9: 6 and 3: 2, respectively. As a result, the ratio Ks: Ms is greater than the ratio Ke: Ma. The slope corresponds approximately to the translation of furniture part-tensioning Ms to power storage-tensioning Ks or of energy storage-relaxing path KE to furniture part discharge Ma. In Fig. 4, the first embodiment of a drive device 1 is shown in an exploded view. This drive device 1 has a housing 8 (base plate). At this housing 8 of the axle 9 is fixed. At the axle 9, the clamping plate 10 is rotatably supported via the recess 23. Furthermore, the axle 12 is rotatably supported on the axle 9 via the recess 24. Around the axle 9 around the ejection force memory 3 in Wrapped or arranged in the form of a leg spring. With the first spring base Fi of the ejection force accumulator 3 is held in the recess 27 of the clamping plate 10. With the second spring base F2 of the ejection force memory 3 is held in the recess 26 of the housing 8. The clamping disk 10 has a total of six regularly arranged locking elements 11 in the form of spring tongues. These spring tongues or locking elements 11 correspond to the six formed in the transmission disc 12 locking stops 13. In the clamping plate 10, an eccentrically arranged recess 25 is formed. In this eccentrically arranged recess 25 engages a bolt of the clamping element 6 a. This tensioning element 6 is guided between the guide elements 31. On the outer periphery of the transmission disc 18, a plurality of teeth 18 is arranged, which mesh with the teeth of the gear 17. This gear 17 is rotatably supported by a pivot pin 34 in the housing 8 formed in the rotary bearing 29. Furthermore, an eccentric axis 30 is arranged on the gear 17. At this eccentric axis 30, one end 16 of the lever 14 is connected via the lever joint pin 32. At the other end 15 of the lever 14, the lever 14 is connected via a lever joint pin 33 with the ejection element 4. This ejection element 4 is again guided in the guide 8 formed on the housing 8. In FIGS. 5a and 5b, the drive device 1 is shown in different views when the movable furniture part 2 is in the closed position SS. In this closed position SS, the movable furniture part 2 is located on the clamping element 6. The locking elements 11 of the clamping plate 10 are applied to the locking stops 13 of the transmission disc 12, since the ejection force memory 3, the Spannscheibei slightly biased counterclockwise. The ejection force accumulator 3 is in the substantially relaxed position E0. If, in the closing direction SR according to FIGS. 6a and 6b, the movable furniture part 2 is pressed, the clamping element 6 is also moved in the closing direction SR. Characterized in that this clamping element 6 is rotatably mounted on the eccentrically arranged recess 25 of the clamping plate 12, the clamping plate 10 is rotated about the axle 9 in a clockwise direction. As a result, the ejection force accumulator 3 reaches a partially tensioned position E50. Through this Movement of the clamping element 6 in the closing direction SR, the clamping plate 10 is rotated relative to the transmission disc 12 in a clockwise direction. As a result, the latching elements 11 lift off from the latching stops 13 and slide under slight bending of the spring-tongue-shaped latching elements 11 along the underside of the gearbox 12. In FIGS. 7a and 7b, the subsequent overpressure position ÜS of the movable furniture part 2 is shown, in which the tensioning element 6 is pressed in completely. As a result, the locking elements 11 are engaged in the (clockwise) nearest recesses with the locking stops 13 in the transmission disc 12. According to FIGS. 7a and 7b, the clamping disk 10 has rotated 60 ° with respect to FIGS. 5a and 5b. This corresponds to the energy storage clamping path Ks, which corresponds to the (relatively short) furniture part-tensioning Ms (see Fig. 5a). In Fig. 7a, the ejection energy storage 3 is in the cocked position E10o- As soon as the movable furniture part 2 is released in this overpressure position ÜS, the ejection force accumulator 3, as indicated in FIGS. 8a and 8b, can relax to a partially tensioned position E70. Since this relaxation movement of the clamping plate 10 takes place counterclockwise, the translation disc 12 is also moved counterclockwise via the locking elements 11 and the locking stops 13. Due to the teeth 18 of this gear 12, which mesh with the teeth of the gear 17, the gear 17 is rotated clockwise. Since this also the eccentric axis 30 connected to the gear 17 and thus also moves the lever 14 via the lever joint pin 32, and the ejection element 4 is moved in the opening direction OR. Since this ejection element 4 in turn rests on the movable furniture part 2, the ejection movement A of the movable furniture part 2 is initiated. Referring to Figs. 9a and 9b, the gear 17 has made a half revolution, whereby the ejection element ejection path Aa is completed. This ejection ejection route Aa corresponds to the furniture ejection route MA. As a result, the movable furniture part 2 enters the first open position OS1. However, since in this first open position OS1 the ejection force accumulator 3 has only relaxed about halfway and thus occupies the partially tensioned position E50, there still remains a residual energy Er in the ejection force accumulator 3. In Fig. 10 it is shown that e.g. has removed the movable furniture part 2 from the ejection element 4 due to the ejection momentum. This can also be done by actively being pulled by a user on the movable furniture part 2. It can be seen in FIGS. 11a and 11b that the residual energy Er of the ejection force accumulator 3 has discharged. As a result, the gear 17 has moved back to its original position and the ejection element 4 is completely withdrawn. The clamping element 6, as well as the ejection force memory 3 and the clamping plate 10, are again in the starting position shown in FIGS. 5a and 5b. In Fig. 12 has moved through the hinges 22 and the movable furniture part 2 again in the closed position SS, where it rests on the clamping element 6. Starting from this closed position SS, a new clamping movement of the ejection force accumulator 3 can start again. In Fig. 13, the second embodiment of a drive device 1 is shown in an exploded view. In this case, the housing 8, the three housing parts 8a, 8b and 8c. In this case, the tensioning device 5 is composed of the first tensioning element 6a, the ejecting force accumulator 3 and the second tensioning element 6b. The axle pin 9 is fixed to the holding recess 37 on the housing part 8a. On the axle pin 9, both the first clamping element 6a and the second clamping element 6b are rotatably mounted. The first spring base F! of the ejection force memory 3 is held in the recess 27 of the first clamping element 6a. The second spring base F2 of the ejection force accumulator 3 is held in the recess 26 of the second clamping element 6b. In the second clamping element 6b, a slot 35 is formed, in which a limiting bolt 36 of the first clamping element 6a engages. Furthermore, this drive device 1 has a holding device 19 for one of the clamping elements 6a, 6b. This holding device 19 has a fixed to the housing 8 pivot bearing 38. At this pivot bearing 38, the pivot lever 39 is pivotally mounted. On the pivot lever 39, in turn, a guide roller 41 is movably mounted. The tension spring 40 is held on the one hand on the pivot lever 39 and on the other hand on the housing 8. In Fig. 14, the drive device 1 according to the second embodiment is shown in the assembled state. It can also be seen that in this case the second clamping element 6b forms the ejection element 4 of the drive device 1. According to FIG. 15, a plan view of the drive device 1 with the movable furniture part 2 is shown. In this case, the movable furniture part 2 is in an open position OS. Since no pressure acts on the clamping elements 6a and 6b from the outside, the ejection force accumulator 36 is in the relaxed position E0. This relaxed position Eo is limited by the fact that the limiting bolt 6 abuts the slot 35 on the right side. It may therefore be quite a certain residual energy in the ejection energy storage 3 may be present. This relaxed position E0 thus corresponds to an "energy-free" ejection energy storage 3, as determined by the limiting bolt 36 and the slot 35. The tension spring 40 of the holding device 19 is stretched and pushes the guide roller 41 to the second clamping element 6b. If, according to FIG. 16, the movable furniture part 2 is moved in the closing direction SR, initially both clamping elements 6a and 6b move synchronously about the axle pin 9 until, according to FIG. 16, the first tensioning element 6a bears against the stop 42 of the housing 8. In this Fig. 16, the ejection force memory 3 is still in the relaxed position E0. If then further pressed on the movable furniture part 2 in the closing direction SR, the drive device 1 enters the position shown in FIG. 17. In this Fig. 17, the ejection force memory 3 is already stretched to a part and is thus in a partially tensioned position E50. The movable furniture part 2 is located approximately in the closed position SS, in which the movable furniture part 2 bears against both the second clamping element 6b and the first clamping element 6a. The fact that the movable furniture part 2 (in the ideal case exactly from the closed position SS) bears against both clamping elements 6a and 6b, both clamping elements 6a and 6b are moved relative to the housing 8 and each other. The second tensioning element 6b moves in the clockwise direction, whereas the first tensioning element 6a moves in the counterclockwise direction. By this relative movement of the clamping elements 6a and 6b to each other and the spring bases Fi and F2 are shifted from each other. The change in the voltage of the ejection force accumulator 3 can also be read at the position of the limiting pin 36 in the slot 35. According to FIG. 18, the movable furniture part 2 has moved even further in the closing direction SR, as a result of which the ejection energy accumulator 3 already occupies a partially tensioned position E7o. As soon as, according to FIG. 19, the movable furniture part 2 rests completely on the housing 8 or on the furniture body 21, the overpressure position ÜS of the movable furniture part 2 is reached. As a result, the cocked position E10o of the ejection force accumulator 3 is reached. Thus, both spring bases Fi and F2 have each covered a part of the energy storage clamping path Ks. Since the discharge roller 41 is no longer applied to one of the clamping elements 6a or 6b, the tension spring 40 can relax and pivots the pivot lever 39 counterclockwise. The limiting pin 36 has reached the left-hand end of the slot 35. As soon as, in the position according to FIG. 19, a user no longer presses on the movable furniture part 2, the ejection energy accumulator 3 begins to relax, as shown in FIG. 20 (the energy E or the triggered torque of the ejection energy accumulator 3 must be present) greater than the locking force of the hinges 22). Since the discharge roller 41 of the holding device 19 bears against the stop 43 of the first clamping element 6a, this clamping element 6a can not rotate or relax in a clockwise direction. Thus, the entire charging energy E of the ejection force memory 3 is used only for a relative movement of the spring base F2 to the housing 8. As a result, only the second clamping element 6b -which thus forms the clamping element 4-moves in the opening direction OR. In Fig. 21, the ejection movement A is completed, which corresponds to the furniture part discharge path Ma. As can also be seen from FIG. 21, the charging energy E of the ejection force accumulator 3 was used only for moving the second tensioning element 6b, whereby the energy accumulator-relaxing path KE is covered. As a result, the furniture part clamping path Ms is smaller than the Möbelteilausstoßweg MA also in this embodiment. In Fig. 21, the pivot lever 39 of the holding device 19 has also rotated in the clockwise direction, since the discharge roller 41 abuts against the deflection bevel 44 of the second clamping element 6b and is pushed by this and thus releases the holding position of the first clamping element 6a. In Fig. 21 and the limiting pin 36 is again reached at the right-hand end of the slot 35, whereby the ejection force memory 3 is in the relaxed position E0. In general, it should be noted that, for example, an electromagnetic or pneumatic energy accumulator or an accumulator can be understood as ejection energy storage. Preferably, the energy accumulator is designed as a spring. The design of the spring is arbitrary again. Thus, the spring may be formed, for example, as a compression spring, tension spring or the like. In both variants of the ejection energy storage is designed as a leg spring, of course, other types of springs can certainly be used in the same functional manner. This is especially true when no rotational movement is used for loading the ejection force accumulator. It should also be noted that the drive device can also have a locking device, preferably having a heart-shaped guideway, for locking the ejection element in a locking position. In the described embodiments, the "locking" in the closed position is achieved in that the hinges hold the movable furniture part. In addition, a "lock" in contrast to many known from the prior art drive devices also not necessary because the ejection energy storage in the closed position is not at all or hardly stretched. It should also be noted that all preferred features of course for both variants - if functionally feasible possible - apply. With regard to the aspect of the invention, according to which at least half of the ejection-force storage tray is inserted during the pushing-over movement, it should be noted that this can be done independently of the ratio of the furniture-part tensioning path to the force-storing tensioning path. This advantage of "clamping when overpressing" is thus also given when the furniture part discharge path is the same size - or equal to "short" - as the furniture part-tensioning during overpressing. Conversely, the opposite of the furniture part Ausstoßweg shorter furniture part clamping is not necessarily dependent on whether this "short" furniture part clamping path is in the range of overpressure. Rather, this "short" furniture part clamping path can also be somewhere between the second open position and closed position. Both aspects of the invention are preferably implemented in a drive device, as is the case with both specific embodiments.
