The invention relates to a drive device for a movable furniture part, in particular for a drawer, with an ejection energy storage having ejection device for ejecting the movable furniture part in an open position and a Einziehkraftspeicher having a draw device for pulling the movable furniture part from an open position to a closed position. In addition, the invention relates to a piece of furniture with a furniture body and a movable furniture part, wherein the movable furniture part is movable by such a drive device.
In furniture construction, especially in Beschlägebau, a variety of tools and methods have been known for many years to facilitate the opening and closing of the movable furniture parts for a user of furniture. Thus, opening devices (so-called ejection devices or, touch-latch mechanisms) have been known for many decades, in which the movable furniture part is ejected and thus opened by pressing on the movable furniture part.
In order not only to facilitate the opening movement for a user, retractors are also known for many years, especially in the last part of the closing path to draw the drawer by itself. This guarantees a safe closing of the movable furniture part. In addition, damping devices are used to prevent excessive impact of a drawer to a strong impact and thus to avoid damage.
A fundamental problem with drive devices or furniture with ejection device and retraction device is that the forces of the respective energy storage counteract each other for ejection or for feeding. That is, it must be ensured with appropriate mechanical means that on the one hand, a secure locking is given and on the other hand each of the right energy storage at the right time and in the right section acts. An important aspect in this technical field is also where and by whom the respective energy store (spring) is tensioned or loaded. In many cases, the ejection force memory is loaded by the operator, for example, when opening or closing the drawer. For loading the Einziehakraftspeichers also the user can apply the necessary clamping force on the drawer itself or the Einziehkraftspeicher is tensioned by the ejection energy storage itself, as this has a greater energy (spring force) than the Einziehkraftspeicher.
An example of a pull-in spring, which is tensioned when opening by the ejection spring, is shown in DE 198 23 305 A1. The tensioning of the recoil spring by hand is described for example in DE 20 2009 009 566 U1. In these two devices, the ejection spring is tensioned each time when closing by hand.
A variant in which only one spring functions both as an ejection spring and as a retraction device is shown in WO 2011/143682.
The object of the present invention is to provide an alternative or improved drive device for a movable furniture part compared to the prior art. In addition, the design and arrangement of the energy storage should be as compact as possible. Furthermore, the spring force should be used as efficiently as possible.
This is achieved for a drive device with the features of the preamble of claim 1, characterized in that the ejection energy storage by the Einziehkraftspeicher loading the movable furniture part is loadable. That is, there must be no manual loading of the ejection force accumulator, but the Einziehkraftspeicher is dimensioned and arranged so that the ejection energy storage is stretched when pulling the drawer.
Since in such an embodiment of the ejection force accumulator is thus equipped with less force than the Einziehkraftspeicher, may preferably be provided that the Einziehkraftspeicher acts with a portion of its energy as a support power storage for ejecting the movable furniture part.
Thus, the Einziehkraftspeicher serves on the one hand for feeding and on the other hand also for ejecting the movable furniture part.
According to a first variant of the present invention, it is provided that only by the ejection force memory, the movable furniture part from the closed position is movable into an open position. That is, the Aüsstoßkraftspeicher itself moves the movable furniture part from its Schließstetlung. As a result, the opening movement can then be provided that the movable furniture part is movable from an open position to a further open position by acting as a support force storage Einziehkraftspeicher.
In contrast, according to a second variant of the present invention, provision can be made for the movable furniture part to be moved from the closed position into an open position only by virtue of the support force memory. That is, the ejection force accumulator does not serve the immediate ejection of the movable furniture part from the closed position. Rather, the movable furniture part can be moved or ejected from an open position into a further open position by the ejection force accumulator.
In general, it can not be ruled out that the individual tensioning paths or expansion paths of the force accumulators overlap. Preferably, however, is provided for the best possible power transmission, that the movable furniture part when ejecting serially in succession by the ejection energy storage and the support power storage is movable. As can be seen from the variants described above, the ejection force accumulator can act first and then the support energy accumulator or vice versa during ejection.
Preferably, it may further be provided that at least one, preferably both, energy accumulators are designed as springs, preferably as compression springs. As a spring can also be understood a spring package, wherein the individual springs of a spring package have the same clamping and / or relaxing path and the same starting and end points of the respective clamping or expansion section. For this purpose, it is preferably provided that the spring constant of the ejection force accumulator is lower
4 is the spring constant of the retractable force accumulator. That is, in the tensioned state of both energy storage, the spring force of Einziehkraftspeichers is higher than the spring force of the ejection force accumulator. After the Einziehkraftspeicher has delivered at least a portion of its energy, the ejection force accumulator on the higher spring force than the remaining spring force in Einziehkraftspeicher and can thus act on the movable furniture part (see, for example, Fig. 3P and Fig. 3Q).
According to a preferred embodiment of the present invention, the drive device, preferably arranged on a furniture body housing, acted upon by Einziehkraftspeicher Einziehschlitten along a slide track in or on the housing movable and locked in a locking position in, preferably a curved portion of the slide track is, and acted upon by an ejection force accumulator ejection carriage which is movable along a Ausstoßkulissenbahn in or on the housing and in a locking position in, preferably a heart-curved portion, the Ausstoßkulissenbahn is lockable on. By such a housing with slide and slide tracks a compact design of the drive device is guaranteed.
It is particularly preferred for this purpose that the Einziehschlitten and the ejection slide are serially movable in succession along the housing. Through this serial circuit is given a compact, narrow and well integrable in a pull-out drive device. Preferably, it is further provided that the ejection force accumulator is attached on the one hand to the housing and on the other hand on the Einziehschlitten. In contrast, the Einziehkraftspeicher is on the one hand attached to the Einziehschlitten and on the other hand on the ejection slide.
In principle, it is possible that the drive device is arranged on the movable furniture part and thus moves along with the movable furniture part. It can, so to speak, repel itself or move in with the furniture body arranged drivers. But it can also be provided that the Einziehschlitten and Ausziehschlitten sections with, preferably arranged on the movable furniture part, drivers are coupled. That is, the drivers are arranged on the movable furniture part and are partially or temporarily coupled with the Einziehschlitten or Ausziehschlitten such that the corresponding movement transfer is guaranteed to pull or ejection to the movable furniture part.
In order to guarantee a safe and smooth closing of the movable furniture part at the end of the closing path, a damping device is preferably provided for damping the retraction movement of the movable furniture part triggered by the retracting energy accumulator.
Protection is also desired for a piece of furniture with a furniture body and a furniture part movable by means of a drive device according to the invention.
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 shows schematically a piece of furniture with an open and a closed movable furniture part,
2A to 2R schematically a first variant of a sequence of a closing and opening movement and
3A to 3R schematically show a second variant of a sequence of a closing and opening movement of a movable furniture part.
Fig. 1 shows a furniture 19, consisting of a furniture body 8 and two movable furniture parts 2 (drawers). These movable furniture parts 2 consist of a drawer 20 and a front panel 21 and are movably supported via a drawer rail 22 on a carcass-resistant carcass rail 23 - which together form the pull-out guide 24. On the drawer 20 (or on the drawer rail 22) drivers 16 and 17 are arranged, which correspond in sections with a arranged on the body 8 and on the carcass rail 23 drive device 1. This drive device 1 has a housing 9, in or on which an ejection slide 10 and a Einziehschlitten 13 are movably mounted. Between the ejection slide 10 and the Einziehschlitten 13 Einziehkraftspeicher 5 is arranged. In contrast, between the Einziehschlitten 13 and the housing 9 of the ejection force accumulator 3 is mounted. The upper of the illustrated drawers is located in a further open position OS1, while the lower of the illustrated drawers is in the closed position SS.
In Fig. 2A, the individual components of a drive device 1 are shown in detail. To this Antriebsvomchtung 1 include on the one hand arranged on the movable furniture part 2 driver 16 and 17 and on the other hand arranged on the housing 9 components. These components are on the one hand the Einziehkraftspeicher 5 (which also acts as a support force memory 7), which together with the Einziehschlitten 13 and the slide track 14 together with curved portion 15 forms the retraction device 6. On the other hand, the ejection force accumulator 3 forms the ejection device 4 together with the ejection slide 10 and the ejection slide track 11 together with the heart-curved portion 12. According to FIG. 2A, the movable furniture part is in a further open position OS1. The tilted Einziehschlitten 13 is located in the locking position VE in the bent portion 15 of the slide track 14. Both trained as a compression spring retracting force accumulator 5 and also designed as a compression spring ejection force memory 3 are shown in their maximum relaxed position. This maximum position is determined due to the slide tracks 14 and 11 and the respective slide 13 and 10.
If, according to FIG. 2B, the movable furniture part 2 is moved manually in the closing direction SR, the driver 17 initially comes into contact with the actuating element 25 of the ejection slide 10. Since the drawing-in carriage 13 is held in the locking position VE, the retraction force accumulator 5 is tensioned by this movement (See further figures 2C, 2D and 2E).
As soon as the position according to FIG. 2F has been reached, the ejection slide 10 enters the heart-curved section 15 of the ejection runway 11 and becomes therein Deflected 7, so that the driver 17 is disengaged from the actuating element 25 of the ejection slide 10.
As soon as the driver 17 is no longer connected to the actuating element 25, the retracting energy accumulator 5 could stretch again. However, since the ejection slide 10 is already in the heart-curved portion 12 of the discharge gate track 11, the control pin 29 is held in the detent recess of the heart cam-shaped portion 12 or pressed by the Einziehkraftspeicher 5 in the detent recess. As a result, the ejection slide 10 enters the locking division VA (see FIG. 2G). Since the driver 17 has detached from the actuating element 25, the movable furniture part is in freewheel F and can be moved by an operator further in the closing direction SR.
At the end of the freewheel F, the driver 17 passes between the catch elements 26 of the Einziehschlittens 13 (see Fig. 2H). In this position, the piston of the damper 18 comes into abutment with the movable furniture part. 2
By further movement of the movable furniture part 2 in the closing direction SR of the Einziehschlitten 13 is moved from its locking position VE and unlocked (see Fig. 2I).
Through this unlocking the Einziehkraftspeicher 5 is free and can relax under retraction or insertion of the movable furniture part 2 in the closing direction SR. The force is transmitted from the Einziehkraftspeicher 5 via the Einziehschlitten 13 and the left catch element 26 further on the driver 17 on the movable furniture part. This power transmission is damped by the damping device 18. In addition, when pulling the ejection force memory 3 is tensioned (see Fig. 2J).
The Einziehkraftspeicher 5 discharges until the driver 16 abuts the actuating element 25 of the ejection slide 10. In this position shown in FIG. 2K, the Einziehkraftspeicher 5 can no longer relax, since it is clamped between the two drivers 16 and 17. In this position is the
Ejecting force storage 3 almost completely stretched and the movable furniture part 2 is in the closed position SS.
In order now to open the movable furniture part 2, is pressed by an operator in the closing direction SR on the movable furniture part 2. As a result, the driver 16 via the actuating element 25 moves the ejection slide 10 and its control pin 29 out of the detent recess of the cardioid-shaped portion 12 and the drive device 1 reaches the over-pressed closed position ÜS (see FIG. 2L).
As soon as the movable furniture part 2 is released after the overpressure, the ejection force memory 3 can relax and move over the Einziehschlitten 13 and the clamped Einziehkraftspeicher 5 the ejection slide 10 and thus subsequently the driver 16 together with movable furniture part 2 in the opening direction OR (see FIG. 2M).
According to FIG. 2N, the ejection force accumulator 3 can continue to relax until the retraction slide 13 reaches the curved section 15 of the slide track 14 (see FIG. 20). As a result, the open position OS is reached and the Einziehschlitten 13 is again in the locked position VE. In addition, in this position, the driver 17 is no longer held between the catch elements 26 and the previously only partially relaxed Einziehkraftspeicher 5 can act as Stützungskraftspeicher 7 and moves the movable furniture part 2 via the ejection force memory 3 and its actuator 25 in the further open position OS1 (see FIG 2P, 2Q and 2R).
In Fig. 2R, the starting position according to FIG, 2A is reached again, with the damping device 18, as known per se, has moved back into the starting position. As a damping device 18, for example, a fluid damper can be used. For the return movement of the damping piston, a return spring can be arranged in the cylinder.
A second variant of the present invention is shown in Figs. 3A to 3R. In contrast to the first variant, the slide track 14 additionally has one
Dodge section 27 on. This does not move the ejection force memory 3, the movable furniture part from its closed position SS but the support power storage 7. The ejection force memory 3, however, moves the movable furniture part 2 from its open position OS in a further open position OS1.
In Fig. 3A it can be seen that the Einziehschlitten 13 is in the locked position VE. In this case, a part of the Einziehschlittens 13 abuts on the only in the opening direction OR traversable reverse lock 28, so that the Einziehschlitten 13 can not move by relaxing the Einziehakraftspeichers 5 in the escape section 27.
FIGS. 3B to 3L correspond to FIGS. 2B to 2L, for which reason a detailed description of this second variant is continued as described below only in FIG. 3L.
By overpressing the movable furniture door in the closing direction SR, the overpressed closed position ÜS is achieved. In this case, the ejection slide 10 is unlocked and moves the movable furniture part in the opening direction OR (see Fig. 3M). By this movement in the opening direction OR, the Einziehschlitten 13 passes through the corresponding configuration of the slide track 14 in the escape section 27. As a result, the driver 17 is disengaged from the catch elements 26 and the release position FS is reached. Thus, in contrast to the first variant (see FIG. 2M), the retraction force accumulator 5 is no longer clamped between the drivers 16 and 17, but the retraction force accumulator 5 can act as a support force accumulator 7 and moves the movable furniture part 2 from the closed position SS into the open position OS (FIG. see Figs. 3N and 30).
As soon as the support force accumulator 7 has relaxed to such an extent that the spring force of the ejection force accumulator 3 is greater than the remaining spring force of the assisting force accumulator 7, the ejection force accumulator 3 can relax and move the movable furniture frame 2 from an open position OS to a further open position OS1 (see FIG. 3P and 3Q). By this relaxation of the ejection force memory 3, the Einziehschlitten 13 moves along the 10 • * · »λ
Ausweichabschnitts 27 and passes over the preferably resiliently mounted reverse lock 28, whereby the Einziehschlitten 13 again enters the locking position VE. In addition, the movable furniture part 2 is moved into the further open position OS1.
In Fig. 3R, the starting position is reached again, in which the movable furniture part 2 is freely movable.
By this invention, a drive device 1 is thus shown with an ejection device 4 and a retraction device 6, on the one hand, the Einziehkraftspeicher 5 when pulling energy to the ejection energy storage 3 and on the other hand, both the ejection force memory 3 and acting as a backup force storage 7 Einziehkraftspeicher 5 when ejecting serially successively act on the movable furniture part 2.
