    The present invention relates to an ejection device for ejecting a movable furniture part of a furniture from an end position with the features of
    Preamble of claim 1.
    From WO 2004/101919 A1 a generic ejection device is known, which causes the ejection movement on the repulsive effect of two magnets. In the local ejection device, the two magnets in the charged state, that is, for example, in a closed position of a drawer, relatively close together. This position thus serves as a force storage for the ejection movement taking place during opening.
    Although this ejection device provides by the use of magnets a desirable ejection characteristic, that is, a high ejection force at the beginning of the ejection movement, which drops quickly. However, the charging characteristic in a magnetic energy storage, so applied by the operator force to bring the magnets together, is not ideal, since just at the end of the charging high forces must be applied. The use of magnets in ejector devices therefore seems to make sense only if the force for charging, as in the cited document, comes from an additional electric motor or the like.
    In addition, the high space requirement of the device known from WO 2004/101919 A1 in the ejection direction must be improved.
    The object of the invention is to provide a magnetically driven ejection device for movable furniture parts, which has a desirable charging characteristic and requires no additional energy source other than the force of the operator.
    This object is achieved by an ejection device with the features of claim 1.
    This is done by the first magnet being released by the triggering movement from a neutral position, in which substantially no repulsive force is acting, into a second position. ················································································································································ % ·································
    Repelling position, in which the repulsive force acts, is movable relative to the second magnet. In other words, the repulsive force of the magnets is indeed as
    Actuator used for the ejector, but not as a force storage - in the charged position, so essentially no force between the magnets acts.
    That there is no force between the two magnets is an unattainable ideal condition. By the expression that "substantially no repelling force acts", it can be understood that the remaining force is not large enough to significantly move the movable furniture part against the existing friction.
    Further advantageous embodiments of the invention are defined in the dependent claims. For a particularly good ejection characteristic, it can be provided that the first magnet can be moved mechanically from the neutral position into the repulsion position.
    In order to achieve that the overall length of the ejection device in the direction of the ejection direction is as short as possible, it can be preferably provided that the first magnet is movable from the neutral position to the ejection position substantially transversely to the ejection direction. For easy and intuitive operation, the triggering movement can be an overpressure movement against the ejection direction.
    A first part for the movable mounting of the first magnet on a furniture body and a second part for fixing the second magnet on the movable furniture part is preferably provided, since this minimizes the total mass of the movable furniture part with attachments.
    Since this avoids the use of an additional drive with the associated energy consumption, it is particularly preferably provided that the first magnet can be moved from the neutral position into the repulsion position by means of an energy accumulator. 3/25 ·· 72354 32 / fr ····· «····· • ·················································································· For a pleasant charging characteristic, that is, a relatively small force over a relatively long distance, care can be taken by using the energy storage as Spring element - preferably as a coil spring - is executed.
    This charging characteristic can be further improved by providing a loading lever and a control cam cooperating with the loading lever for loading the force accumulator during a movement bringing the movable furniture part into the end position. The force-displacement ratio during the charging movement can be finely adjusted via the lever ratios on the charging lever.
    The cam is preferably formed substantially in the shape of a trapezoid with preferably rounded corners, which has a clean separation of the various movements without rapid force changes result.
    In order to avoid unwanted or accidental release of the ejection device, it can be provided that the first magnet can be locked by a trigger latch in the neutral position.
    In particular, when the triggering movement is an overpressure, the unlocking can be particularly easily solved by the release latch is unlocked by a release movement transmitting, preferably triangular, release lever.
    A locking device for locking the movable furniture part in the end position may be provided to prevent unwanted movement of the movable furniture part.
    Characterized that, the movable furniture part until it reaches the repelling position by the first magnet by means of the locking device in the end position can be locked and only when reaching the repelling position of the first magnet releases the movable furniture part, the desired ejection characteristics of the magnets can be fully utilized. 4/25 ···· ·· 72354 32 / fr: 4: · ♦ · ·
    Protection is also sought for a piece of furniture with an ejection device according to the invention.
    A particularly space-saving design can be realized by the first magnet is movably mounted on a furniture body of the furniture and that the second magnet is attached to the movable furniture part.
    Further advantages and details of the invention will become apparent from the figures and the associated description of the figures. Show
    1a shows a piece of furniture with an ejection device according to the invention and a movable furniture part in a closed position, FIG. 1b shows a piece of furniture with an ejection device according to the invention and a movable furniture part in a partially open position, FIG.
    2a to 2h show a sequence of plan views of the invention
    Ejecting device to illustrate the principle of operation as well
    Fig. 2i is a plan view of the ejection device according to the invention during charging of the force accumulator.
    Figure 1a shows a piece of furniture 1, in which a movable furniture part 2 is designed as a drawer. In a space between a rear wall 15 of the drawer and the furniture body 14 sits the ejection device. 3
    FIG. 1 b is a representation similar to FIG. 1 a, the movable furniture part 2 being partially ejected, as a result of which the ejection device 3 is better visible.
    In the figure 2a, the ejection device 3 is shown together with the rear wall 15 of the movable furniture part 2. For reasons of clarity, the rest of the movable furniture part 2 has not been shown. The first magnet 4 is here in the neutral position, which in this embodiment is realized by a transverse displacement with respect to the ejection direction X of the first magnet 4 to the second magnet 5. 5/25 ·· ···· ·· · · · · 72354 32 / fr ····
    The first magnet 4 is mounted together with a force accumulator 8 and other components on the first part 6 of the ejection device. The second magnet 5 is attached via the second part 7 to the rear wall 15 of the movable furniture part 2.
    The position of the first magnet 4 is held by a bolt 11, which prevents the discharge of the force accumulator 8. As can be seen in Figure 2b, the lever 12 is actuated by an overpressure against the ejection direction X, whereby the latch 11 is unlocked.
    In Figure 2c, the force accumulator 8 is partially discharged, whereby the first magnet 4 is on the way to the repelling position. By the locking device 13, however, the movable furniture part 2 is still held in the current position, although a certain force between the first magnet 4 and the second magnet 5 already acts. The movement of the first magnet 4 also causes a movement of the loading lever 9. This is rotatably mounted on a loading lever joint 16 on the furniture body 14, not shown in this figure. The cam 10 is attached to the non-illustrated part of the movable furniture part 2, resulting in simple leverage.
    In FIG. 2d, the first magnet 4 is now in the repelling position. An arranged in the designed as a helical spring force accumulator 8 bolt releases the locking device 13.
    This leads to the beginning of the ejection movement, which is shown in Figure 2e. At a later time in this movement is the presentation of Figure 2f before. Since the control cam 10 is indeed fixed to the movable furniture part 2, the movement of the control cam 10 in this representation is synchronous with the rear wall 15th
    In FIG. 2g, the first magnet 4 and the second magnet 5 are now far enough away from each other that substantially no force acts. As a result of which the loading lever 9 is spring-loaded, the loading lever 9 lies with its end facing the first part 6 again against a bearing part for the first magnet 4.
    In Figures 2e and 2f, this was prevented by the control cam 10 to a 6/25
    Moving away the first magnet 4 from the repelling position by the spring-loaded loading lever 9 to prevent.
    Due to the built-up speed and optionally by the force of the operator, the movable furniture part 2 is opened further. This is shown in FIG. 2h. By the spring action of the loading lever 9 is brought to the end of the ejection movement out with the bottom of the control cam 10 shown in the figure in Appendix. If now the movable furniture part 2 is closed again, as shown in Figure 2i, is charged by the interaction of the loading lever 9 with the control cam 10 of the energy storage device 8 again.
    It can also be seen in FIGS. 2g and 2h how the release lever 12 is rotatably mounted on the first part 6 via a release lever joint 17, which enables a particularly simple transmission of the release movement into an unlocking movement of the release latch 11.
    The present invention is not limited to the illustrated embodiment. The energy storage, for example, even be designed even magnetically. The loading of the triggering device, that is, the return of the first magnet 4 in the neutral position, but can for example also be solved by means of an additional drive as mentioned in the prior art. Here there is the advantage that the additional drive can be made smaller, since it does not have to drive against the force of the magnets.
