DETAILED DESCRIPTION OF THE INVENTION
(18) FIG. 1 shows an article of furniture 13 comprising a furniture carcass 14 and furniture parts 2 mounted moveably therein. Those moveable furniture parts 2 in the form of drawers are linearly displaceably supported by an extension guide device 16 on the furniture carcass 14. The extension guide device 16 has a carcass rail 18, a drawer rail (not shown here) and possibly a central rail. The drive device 1 is fixed to the extension guide device 16 or the moveable furniture part 2.
(19) In that respect, it can be seen from FIG. 2a that the drive device as essential components has an ejection lever 7 and the ejection force storage member 6 which at the same time serves as a retraction force storage member 11. There is also a damping device 19.
(20) It can be seen in detail from FIG. 2b that the ejection lever 7 bears against the ejection abutment 27 by way of the ejection roller 20. The ejection roller 20 is mounted rotatably to the ejection lever 7 by way of the rotary bearing 29. In principle, the ejection lever is mounted to the ejection base plate 26 rotatably about the pivot axis X. In this embodiment, the ejection base plate 26 is mounted to a drawer bottom underside of the moveable furniture part 2. The ejection force storage member 6 is fixed by way of the first spring base 24 to the ejection base plate 26 and by way of the first spring base 25 to the ejection lever 27. The ejection force storage member 6 is in the form of a tension spring. In contrast to the ejection base plate 26, the locking base plate 8 is mounted to the carcass rail 18. The ejection abutment 27 is arranged on that locking base plate 8. In addition, the control element 21 is mounted moveably in the release direction R on the locking base plate 8. The control element 21 is acted upon by a force in the release direction R by a force storage member (not shown here). In addition a force-actuated flap 23 is rotatably mounted to the control element 21. The damping device 19 has a damping piston 28, the damping piston 28 bearing against the slider 34. The slider 34 bears against the ejection lever 7 in particular shortly before reaching the closed position SS and damps the retraction movement of the ejection force storage member 6 which operates as the retraction force storage member 11. For movement of the moveable furniture part 2 in the opening direction OR, the moveable furniture part 2 bears against the ejection abutment 27 formed or arranged on the furniture carcass 14, by way of the ejection lever 7 arranged on the moveable furniture part 2.
(21) FIGS. 3a through 3c show various views of the drive device 1, that position of the drive device 1 corresponding to the closed position SS of the moveable furniture part 2. It will further be seen that the blocking element 4 mounted rotatably to the control element 21 is in a release position F. The locking element 9 which in FIGS. 3a through 3c is in the locking position V is connected to the control element 21 or is provided in one piece therewith. In that locking position V, the ejection lever 7 bears against the locking element 9 by way of the ejection roller 20. The force storage member (not shown) which is operative between the locking base plate 8 and the control element 21 admittedly seeks to move the locking element 9 in the release direction R, but that is prevented by the ejection lever 7 bearing against the locking lever 9 as the force of the ejection force storage member 6 is greater than that of the force storage member (not shown) between the locking element 9 or the control element 21 and the locking base plate 8.
(22) When now pressure is applied to the moveable furniture part 2 in the closing direction SR, the moveable furniture part 2 passes into the over-pressing position S, in which case then the drive device 1 is in the position shown in FIGS. 4a and 4b. The ejection base plate 26 also moves relative to the locking base plate 8 by virtue of the movement of the moveable furniture part 2 in the closing direction. However, in accordance with the closed position SS, the ejection roller 20 of the ejection lever 7 already bears in the closed position SS against the ejection abutment 27. Thereforem, the ejection roller 20 cannot move further in the closing direction SR when the moveable furniture part 2 moves into the over-pressing position S, but a pivotal movement of the ejection lever 7 about the pivot axis X is triggered. Admittedly, by virtue of that pivotal movement, the ejection roller 20 remains in the same position, as viewed in the closing direction SR, but the situation involves a movement of the ejection roller 20 transversely relative to the closing direction SR or the opening direction OR. As a result, the ejection roller 20 is moved away from and brought out of contact with the locking element 9 until the control element 21 together with the locking element 9 can move past the ejection roller 20 into the release direction R, by virtue of the force storage member (not shown). Accordingly, the locking element 9 moves out of the locking position V into the release position G whereby the ejection lever 7 is no longer held to the locking element 9, and so the path of movement into the ejection portion A is free.
(23) As soon as that ejection portion A is no longer locked by the locking element 9 the ejection force storage means 6 can be relieved and pivots the ejection lever 7 in the counter-clockwise direction into the position in FIGS. 5a through 5c. With that pivotal movement the ejection lever 7 comes to bear by way of the ejection roller 20 against the ejection abutment 27 of the ejection base plate 26 and moves the moveable furniture part 2 relative to the furniture carcass 4 in the opening direction OR. Accordingly the moveable furniture part 2 is disposed in an open position OS as shown in FIGS. 5a through 5c. The locking element 9 is still in the release position G.
(24) Because the ejection force storage member 6 is further relieved, the drive device 1 moves further into the positions shown in FIGS. 6 and 7.
(25) The drive device moves further into the position shown in FIG. 8 by the inertia of the ejection device 3 or by manually pulling on the moveable furniture part 2 in the opening direction OR. In that position, the moveable furniture part 2 is in a free-running condition. When the moveable furniture part 2 is moved from FIG. 8 further in the opening direction OR, the flap 23 allows the ejection roller 20 to pass, with a pivotal movement in the clockwise direction.
(26) When the moveable furniture part 2 is then moved again in the closing direction SR, the ejection roller 20 comes into contact with the stressing portion S provided on the flap 23 and the control element 21 (see FIG. 9). As soon as the ejection roller 20 contacts the control element 21 or the flap 23, the entire control element is moved against the force of the force storage means (not shown) in opposite relationship to the release direction R whereby the locking element 9 passes into the locking position V.
(27) Upon further movement of the moveable furniture part 2 in the closing direction SR, the ejection roller 20 is displaced or rolls along the stressing portion S to the position shown in FIG. 10 in which the ejection force storage member 6 is fully stressed. The stressing portion S with the retraction portion E and the ejection portion A form the essential components of the control path 12.
(28) After moving beyond the position shown in FIG. 10 in the closing direction SR, the ejection lever 7 moves into the retraction portion E as shown in FIG. 11, in which case the ejection lever 7 now operates as a retraction device 35, in cooperation with the retraction force storage member 11. By virtue of the mechanical contact between the ejection roller 20 and the control element 21, the control element 21 is further pushed in opposite relationship to the release direction R so that the locking element 9 remains in the locking position V.
(29) As a further consequence the ejection roller 20 comes into contact with the rotary lever 30 of the blocking element 4, as shown in FIGS. 12a through 12c. By virtue of that contact the blocking element 4 is rotated in the clockwise direction about the rotary bearing 32. As a result, the blocking cam 31 is also displaced in the guide path in the locking base plate 8. Simultaneously with that rotary movement, the resetting device 5 which is in the form of a tension spring is also stressed. That tension spring is fixed on the one hand to the control element 21 and on the other hand to the blocking element 4. As shown in FIGS. 12a through 12c the blocking element 4 is thus already in the blocking position B.
(30) By virtue of the relief of the retraction force storage member 11, the drive device 1 moves further into the position shown in FIGS. 13a through 13c in which the moveable furniture part 2 is still in an open position OS. During that retraction movement, the effect of the damping device 19 also takes place and opposes the spring force of the retraction force storage member 11. As shown in FIGS. 13a through 13c the blocking element has rotated further in clockwise direction so that the blocking cam 31 reaches the end of the guide path 10. The resetting device 5 is fully loaded in that position.
(31) Soon after the ejection roller 20 is no longer in contact with the rotary lever 30, the ejection roller 20 and the ejection lever 7 pass into a position shown in FIG. 14 corresponding to the closed position SS of the moveable furniture part 2. In that case, the ejection roller 20 bears against the locking element 9. The blocking element 4 is admittedly no longer contacted by the ejection roller 20 but nonetheless it is still in the blocking position B, but it has already covered a part of the resetting movement T by virtue of the resetting device 5. That resetting movement T is however time-delayed by a delay device. That delay device can be, for example, in the form of a rotational damper in the rotary bearing 32. That delay device provides that the movement of the blocking element 4 from the blocking position B into the release position F lasts between 0.2 second and 4 seconds. The ejection device 3 cannot be unlocked during that period, which is illustrated by FIGS. 15a through 15b which are described hereinafter.
(32) Particularly by a comparison with FIG. 4a, it can be seen more specifically in FIG. 15a that the ejection lever 7 has rotated in the clockwise direction about the pivot axis X again by virtue of the movement of the moveable furniture part 2 into the over-pressing position S. As a result, the ejection roller 20 moves away from the locking element 9, whereby that locking element 9 actually seeks (is urged) to move in the release direction R by way of the control element 21 by virtue of the force storage member (not shown). It will be noted, however, that that movement in the release direction is prevented as shown in FIG. 15b by the blocking cam 31 of the blocking element 4 bearing against the blocking flank 33 of the guide path 10 in the locking base plate 8. Thus, at most a slight movement of the locking element 9 in the release direction R is possible, but it is not sufficient to release the ejection portion A for the ejection lever 20. Thus, upon over-pressing of the moveable furniture part 2 into the over-pressing position S, as long as the blocking element 4 is in the blocking position, the ejection device 3 cannot be unlocked. As long as pressure is still applied to the drawer (moveable furniture part) which is in the over-pressing position S by an operator, the blocking element 4 cannot be moved into the release position F by the resetting device 5. That is because the ejection roller 20 does not bear against the locking element 9 fullyas is the case in the closed position SSbut the locking element 9, by virtue of the force storage member (not shown), is displaced with respect to the closed position SS by a short distance in the release direction R. By virtue of that displacement, the axis of rotation of the rotary bearing 32 no longer coincides with the configuration of the guide path 10 and the blocking cam 31 cannot move along the guide path 10 in the counter-clockwise direction but is wedged against the blocking flank 33 (see FIG. 15b). This means that, as long as an operator is pressing against the moveable furniture part 2 when in the over-pressing position S no movement of the blocking element 4 into the release position F can take place.
(33) It is only when the moveable furniture part 2 is released that the ejection force storage member 6 can be relieved somewhat again and pivot the ejection lever 7 in the counter-clockwise direction so that the locking element 9 moves into the position shown in FIG. 14 again by way of the ejection roller 20. In that FIG. 14 position, the axis of rotation of the rotary bearing 32 again coincides with the radius of the guide path 10 so that the resetting device 5 can move the blocking element 4 in the counter-clockwise direction in time-delayed relationship into the release position F shown in FIG. 3c. In that FIG. 3c, the blocking cam 31 has overcome the blocking flank 33 and the blocking element 4, when the moveable furniture part 2 is over-pressed into the over-pressing position S, can also be moved along the straight portion 36 of the guide path 10 with the control element 21 and the locking element 9 in the release direction R so that, as shown in FIG. 4b, the ejection portion A is cleared for the ejection roller 20.
(34) FIG. 16 diagrammatically shows a time-travel graph illustrating the position of the moveable furniture part 2 during a closing operation without being pushed beyond the closed position. At the beginning of the closing movement, accordingly, the blocking element 4 is still in the release position F. At the same time, the drive device 1 is moved along the stressing travel distance S and then reaches the retraction portion E. During the movement of the moveable furniture part 2 in the retraction portion E, the blocking element 4 is moved from the release position F into the blocking position B or switched over. When the closed position SS is reached, the blocking element 4 is also in the blocking position B. As, upon normal closing, when the closed position SS is reached, no force is exerted from the exterior on the moveable furniture part 2, and the resetting movement T begins at the latest when the closed position SS is reached. With the end of that resetting movement T, the blocking element 4 also moves from the blocking position B into the release position F again. Then, as indicated by the dotted illustration, it is possible to wait for unlocking as long as may be desired. As soon as an operator would like to open the moveable furniture part 2 he presses against the moveable furniture part 2, in the closing direction SR whereby the moveable furniture part passes into the over-pressing region between the closed position SS and the over-pressing position S. In that way, the ejection device 3 is unlocked and the moveable furniture part 2 is ejected in the opening direction OR.
(35) In comparison, FIG. 17 diagrammatically shows the protection afforded by the present invention against the moveable furniture part being pushed through beyond the closed position. Once again, firstly at the beginning of the closing movement, a free-running portion (not shown) is moved by the moveable furniture part 2. As soon as the ejection roller 20 comes into contact with the control element 21, the stressing portion S of the drive device 1 is reached. During the movement along the retraction portion E, the blocking element 4 is moved into the blocking position B from the release position F. Subsequently upon reaching the closed position SS the moveable furniture part 2 is not stopped but the moveable furniture part is immediately pushed through into the over-pressing position S. As the blocking element 4 is in the blocking position B the ejection device 3 cannot be unlocked and there is no ejection of the moveable furniture part 2 in the opening direction OR in spite of the over-pressing action on the moveable furniture part. As long as the moveable furniture part 2 remains in the over-pressing position S, the blocking element 4 also remains in the blocking position B (see the dotted line). It is only when the moveable furniture part 2 is released that the moveable furniture part 2, by virtue of the ejection force storage member 6 and the ejection lever 7, moves into the closed position SS again (see the releasing portion L). As soon as the moveable furniture part 2 is in that closed position SS the resetting movement T also begins again, produced by the resetting device 5. After the same period as in FIG. 16, that resetting movement T is concluded and the blocking element 4 again moves from the blocking position B into the release position F. Then, as in FIG. 16, it is possible to wait for triggering or unlocking as long as may be desired. Unlocking is again effected by over-pressing into the over-pressing position S and then ejection of the moveable furniture part 2 by the ejection device 3 in the opening direction OR.
(36) FIGS. 18 through 23b show a further embodiment of the present invention in which in particular the blocking element 4 is of a different configuration. In that respect, attention is firstly directed to FIG. 18. That FIG. 18 corresponds to the position of the drive device 1 as shown in FIG. 9. In other words, the moveable furniture part 2 has just been closed and the ejection roller 20 bears against the stressing portion S of the control element 21. That provides that the entire control element 21 is moved like from FIG. 8 to FIG. 9. With that movement, the blocking cam 31 is also moved towards the left along the guide path 10 in the locking base plate 8 until the blocking cam 31 contacts the diversion edge 38 as shown in FIG. 18. In FIG. 18 the moveable furniture part 2 is in the open position OS. The locking element 9 is already in the locking position V. In this embodiment, the locking element 9 at the same time forms the blocking element 4, being rotatable about the rotary bearing 32.
(37) When as shown in FIG. 19 the control element 21 is further moved in the stressing phase, the blocking cam 31 is deflected by the diversion edge 38 whereby the blocking element 4 rotates in the counter-clockwise direction. Disposed in the region of the rotary bearing 32 or the blocking element 4 is a damping medium which takes over the function of the resetting device 5. The blocking element 4 is thus in the blocking position in FIG. 19.
(38) As shown in FIGS. 20a and 20b, in the further closing process, the ejection roller 20 passes beyond the locking element 9 or the blocking element 4 whereby the closed position SS of the moveable furniture part 2 is reached.
(39) If the moveable furniture part 2 is immediately pushed further through into an over-pressing position S, as shown in FIGS. 21a and 21b, the ejection roller 20 admittedly lifts off the locking element 9, but there is only a short movement of the entire control element 21 as that movement is immediately stopped by the control cam 31 meeting the control flank 33. Thus, the blocking position B is at least temporarily maintained in that over-pressing position S.
(40) After a short period of a few seconds the blocking element 4 is rotated in the clockwise direction again by virtue of the yielding force of the damping medium whereby the blocking element 4 passes into the release position F shown in FIGS. 22a and 22b. The ejection roller 20 however is still bearing against the blocking element 4 or the locking element 9, and for that reason no unlocking and thus no ejection occurs, on the basis of the prevailing locking position V.
(41) It is only when normal or desired over-pressing is effected, starting from that position, that unlocking and ejection as already described in relation to FIGS. 3 and 4 take place. In that case, as in FIGS. 23a and 23b, the ejection roller 20 passes into the ejection portion A as that was enabled by the control element 21. In that movement of the control element 21 towards the right the blocking cam 31 also moves along the guide path 10.
(42) Thus the present invention provides an alternative protection against the moveable furniture part being pressed through beyond the closed position, in which unlocking of the ejection device 3 is prevented for a certain time after the closed position SS is reached. Unlocking is entirely prevented as long as the moveable furniture part 2 is still in the over-pressing position S, after having been pressed beyond the closed position.
(43) In the embodiment shown in this application, the ejection lever 7 is associated with the moveable furniture part 2 and bears against an ejection abutment 27 associated with the furniture carcass 14. In principle, however, the reverse variant is also conceivable, wherein an ejection lever 7 associated with the furniture carcass 14 ejects the moveable furniture part 2. The individual components can be fixed to the extension guide assembly 16 in respect of all thereof, some or not at all. That variant of the protection against over-pressing correspondingly applies to all variant configurations. In particular, this over-pressing protection does not necessarily have to be limited to an ejection device 3 with a pivotable ejection lever 7, but it can naturally also be correspondingly implemented in the case of a linearly moveable ejection element with a cardioid-shaped guide path. Besides a drawer the moveable furniture part 2 can also be a furniture flap, furniture door or the like.
