EP2793655B1 - Arrangement for moving a moveable furniture part - Google Patents

Description

The invention relates to an arrangement for moving a movable furniture part, in particular a drawer, with at least one ejection device for ejecting the furniture part from the closed position to a first open position, wherein the at least one ejection device comprises at least one energy storage, and at least one charging device for loading the at least an energy storage device by a closing movement of the furniture part, wherein the loading of the at least one energy storage device takes place via a charging path with an end point, and wherein the at least one energy storage device is completely charged at the end point of the charging path.

Such arrangements for moving a movable furniture part already belong to the prior art and are eg in the DE 198 23 305 A1 and in the EP1396212 A1 described. In the known solutions, the end point and the starting point of the charging path are fixed. This means that when the movable furniture part is arranged in or on a furniture body, the end or starting point of the charging path is located at a fixed relative to the furniture body body. The disadvantage here is that you have to open the furniture part at least to the starting point of the charging path, this starting point can also correspond to the fully open position of the furniture part, so that the energy storage can be fully loaded by the closing movement of the furniture part. Otherwise, the ejector is only partially functional.

Object of the present invention is to avoid the disadvantages described above and to provide a comparison with the prior art improved arrangement for moving a movable furniture part.

To achieve this object, the invention provides that the charging path has a variable starting point, wherein the starting point of the charging path at a closing movement of the furniture part from a second open position, which is greater than the first open position determined by the position of the furniture part at the beginning of the closing movement is.

It is advantageous that this variability of the starting point of the charging path ensures that the energy storage is always fully charged - regardless of how far the furniture part (beyond the end point of the charging path or the first open position addition) is opened. In a - regardless of Ausziehweg the movable furniture part - arranged relative to the furniture body at a fixed point end of the charging path, this means that the arrangement is designed such that by the starting point, the force to load the at least one energy storage is set: Is the movable furniture part Little open, so it is a short charging path and it must be applied a relatively large force to fully load the energy storage during the closing movement. On the other hand, if the furniture part is e.g. completely open, so there is a comparatively large charging distance and it must be spent significantly less force to fully load the energy storage.

In an advantageous embodiment of the invention, the at least one energy accumulator comprises a spring, preferably a leg spring. In this case, the fact that the charging path has a variable starting point and the starting point of the charging path is determined by the position of the furniture part at the beginning of the closing movement that, depending on the starting point of the charging path, the slope of the spring characteristic is adjusted: This is a long charging distance It is a flat, with a short charging distance around a steep spring characteristic.

It should be noted in advance that in the Fig. 4 to 15 the same representation (schematically and in plan view from below) as in the Fig. 3 was chosen.

Fig. 1 shows a schematically illustrated perspective view of a drawer box with a furniture body 6 and three in or on the furniture body 6 movably mounted furniture parts 2 in the form of drawers. The drawers 2 are each composed of a drawer bottom 17, two side frames 15, a rear wall 16 and a front panel 14.

In the Fig. 2a a section of the furniture body 6 is shown together with a drawer 2. It can be seen that the drawer 2 on two sides of the drawer. 2 arranged pullout guides 18 are in communication with the furniture body 6 (in this figure, only one of the two extension guides 18 is visible). In the illustrated form, the pull-out guide 18 is comprised of three parts: a carcass rail secured to the furniture body 6, a drawer rail secured to the drawer 2, and a center rail movably mounted between the drawer rail and the carcass rail. By means of pull-out guides in this three-part form, a so-called full extension of drawers can be realized. However, other pull-out guides belonging to the prior art should not be excluded from the idea of the invention.

The Fig. 2b shows a view of the in the Fig. 2a shown combination of a part of the furniture body 6 and a drawer 2 obliquely from below. In this view it can be seen that a part of the arrangement 1 for moving the drawer 2 (in the preferred embodiment) is arranged on the underside of the drawer bottom 17 and another part of the arrangement 1 on the cabinet rails of the two extension guides 18. Furthermore, it can be seen that the arrangement 1 in this embodiment consists of two halves, which are substantially mirror-symmetrical to one another. The imaginary mirror axis is indicated by a dashed line. The two halves each comprise an ejection device 3 for ejecting the drawer 2 from the closed position into an open position, this ejection device 3 also simultaneously acting as a collection device for drawing the drawer 2 into the closed position. In addition, the arrangement 1 also includes a damping device 13 for damping the retraction movement of the retraction device 3. The damping device 13 and the retraction device 3 are connected via an angle plate 20 with the body rail of the pull-18 (the angle plate 20 has been omitted on the left side). This means that these parts of the assembly 1 are firmly connected to the furniture body 6 and do not change their position relative to the furniture body 6 during a movement of the drawer 2. The remaining components of the arrangement 1 (in the preferred embodiment) are arranged on the underside of the drawer bottom 17 and thus change their position relative to the furniture body 6 when the drawer 2 moves.

The details of the individual components and the mode of operation of the arrangement 1 will be described in more detail below with reference to FIG Fig. 3 to 15 explained. One can be seen each Top view of the in the Fig. 2a and 2b shown unit of a part of the furniture body 6 and a drawer 2 from below, the two actually existing angle plates 20 have been omitted and for understanding the operation of the arrangement 1 important components of the assembly 1, which you would not actually see because of others Components are hidden, dashed lines are shown.

Fig. 3 shows the closed position of the drawer 2. Let attention first be directed to the ejection devices 3, wherein the ejection device 3 arranged on the left pull-out guide 18 is shown enlarged. In this enlarged representation, it can be seen that the ejection device 3 comprises a mounting plate 30 on which a force accumulator 4 rotatably mounted about a rotation axis 31 is arranged, wherein the rotational movement of this force accumulator 4 is limited by the fact that a pin 21 is arranged on the force accumulator 4 is that projects into a guide track 28 in the mounting plate 30, wherein this pin 29 can move only in this guideway 28. Due to the design of the guide track 18, the force accumulator 4 can perform only a rotational movement by about 90 °.

The energy accumulator 4 comprises a spring 17, more precisely a leg spring, in which the actual energy of the energy accumulator 4 is stored. When the pin 29 of the energy accumulator 4 is located on the left upper stop of the guideway 28, the energy accumulator 4 is fully charged. If it is at the lower right stop point, it is completely unloaded.

Furthermore, a bolt-shaped driver 7, which plays an essential role for the functioning of the arrangement 1, is arranged on the energy store 4. In the closed position shown, it ensures that the ejection device 3 is in a partially charged state (the cone 29 is located in a middle position) Position and the leg spring 27 is partially stretched) is locked and the energy storage device 4 can not discharge. This is achieved by arranging on the loading device 5 to be described a locking device 12 in the form of a latching nose, which is designed in such a way that the carrier 7 of the energy store 4 can not move in the direction of the unloaded position when the carrier 7 is in the closed position of the drawer 2 bears against the latching lug. This situation is something more precisely in the enlarged section of the ejection device 3 arranged on the right pull-out guide 18. It should also be noted that, of course, other known to the expert solutions can be used instead of a locking lug, such as an at least partially heart curve trained locking and unlocking.

In the Fig. 4 it is shown how this locking of the ejection device 3 can be canceled by unlocking. It is thus at the same time at the locking device 12 to an unlocking device. The unlocking is effected by the fact that the drawer 2 is pressed by the user in the direction of the rear wall of the furniture body 6. As a result, the tip of a support device 8, which is arranged on the drawer bottom 17, strikes the driver 7, as a result of which this driver 7 is pressed against the latching lug 12. It should be noted that the locking lug 12 at the end of a control rail 10, which includes the loading device 5, is arranged, said control rail 10 is rotatably mounted about an axis of rotation 26, whereby the position of the control rails 10 with respect to the drawer. 2 or the furniture body 6 is changeable. The control rail 10 is spring-loaded by a spring 24. In the closed position, there is a balance of forces between the spring 24, which acts on the control rail 10, and the leg spring 27 in the energy accumulator 4, which acts on the driver 7. However, this balance of forces is affected when unlocking to the effect that the driver 7 is pressed against the locking lug 12. As a result, the locking lug 12 and thus the control rail 10 pivots slightly to the side, and indeed so far that the driver 7 overcome the projection of the locking lug 12 and can slide down. The driver 7 is decoupled in this way from the control rail 10.

In the Fig. 5 is the ejection then ejection process, which is mediated by the ejector 3, shown. After unlocking the driver 7 strikes a partially curved control contour 9, which is arranged on the support device 8, and slides along this, since the leg spring 27 of the energy accumulator 4 would like to relax. The energy thus released is transferred to the support device 8 and thus to the drawer 2, which leads to a discharge movement of the drawer 2 from the closed to a first open position. The energy transmitted by the two ejection devices 3 is sufficient to eject the drawer 2 (depending on the load condition) by several centimeters, at least so far that the user can reach under the front panel of the drawer 2 and subsequently open the drawer 2 manually. An essential aspect of such ejection devices is therefore to be able to use drawers on the fronts no handles must be attached to open the drawers can.

Comparing the Fig. 4 and 5 , it can be seen that in the ejection movement of the drawer 2, the two control rails 10 of the charging devices 5 have moved towards the middle of the drawer and now abut stop contours 31 and 32. The spring 24, which is arranged between the two control rails 10, has relaxed in this ejection movement.

If you look at the upper end of the control rails 10 a little closer, so it is found that there each a small tip protrudes in the direction of the rear wall of the drawer. It could give the impression that through these tips the movement of the two control rails 10 from the position shown in the Fig. 4 is shown in the position which in the Fig. 5 shown could be hampered. But if you look at the Fig. 6 which shows an enlarged section of the area of the drawer rear wall, it can be seen that the two tips are in each case one arm of a two-armed rocker arm 22, wherein the other arm of the rocker arms 22 are each spring-loaded by means of a spring 23. Now move the two control rails 10 in the direction of the middle of the drawer, so the free arms of the rocker arm 22 abut against the edge of a partially stepped Verrastkontur 21, whereby the rocker arm 22 are tilted to the side and clear the way for the movement of the control rails 10. After reaching the in the Fig. 5 shown position, the rocker arms 22 are no longer at the Verrastkontur 21, the springs 23, which were forcibly tensioned, relax again and the rocker arms 22 move under the spring action back to its original position.

In the Fig. 7 to 10 Now the further manual opening operation of the drawer 2 is shown by the user. In this opening process, only very low frictional forces occur, since in this opening process, only the spring 24, but not the two torsion springs of the energy storage 4 are loaded. From the comparison of FIGS. 5 and 7 It can be seen that the drivers 7 of the energy accumulator 4 initially move into a guideway oriented parallel to the drawer sidewalls in this position of the control rails 10 within the control rails 10 (which is shown in FIGS Fig. 5 indicated by whistle) - thereby occur in renewed coupling with the control rails 10 - and thereby each push a also about the rotation axis 26 rotatably mounted one-armed pivot lever 25 to the side. This situation is in the enlarged section of the right-hand control rail 10 in the Fig. 7 to see.

In the Fig. 8 is the drawer 2 so far open that the driver 7 have each overcome the pivot lever 25 and are now in a second section of the guideway of the control rails 10. It should be noted that the two pivot levers 25 are each spring-loaded by a (not to be seen) small spring and thereby held in a position in which the upper portions of the pivot lever 25, the first section of the guideway, the driver 7 first traverses have closed. Although it is not the small spring to see, but probably the two spring application points, between which the spring is clamped and which are arranged above the pivot point 26.

Fig. 9 shows a position of the drawer 2, in which the drawer 2 is still opened a little further. Since the ejection devices 3 are respectively connected to the carcass rail of the pull-out guides 18 and the force for loading the energy accumulator 4 is greater than the force that must be applied to pivot the two control rails 10 in the direction of the two drawer side walls, the drivers 7 keep their Position and force the control rails 10 to pivot outwards, ie in the direction of the drawer side walls. The two arranged at the end of the control rails 10 rocker arm 22 (see Fig. 6 ) are thereby tilted in the opposite direction of rotation in comparison to the movement described above and their free arms "hop" thereby from stage to stage of Verrastkontur 21st

The Fig. 10 shows the end position of the drawer 2, in which the drawer 2 is fully open. In this position, the two drivers have 7 from the second section of the guideway in the two control rails 10 is slightly moved out. The two small rocker arms 22, which are arranged at the end of the two control rails 10, are each with their free arm on the last stage of Verrastkontur 21st

In the Fig. 11 to 13 is now the closing of the drawer 2 from in the Fig. 10 shown end position, said end position represents a possible second open position within the meaning of claim 1, which is greater than the first open position represents. The addition "which is greater than the first open position" thus means that the drawer is pulled out further. At the beginning of the closing movement from this end position, the two drivers 7 initially move back into the two. Guideways of the control rails 10 back. This is facilitated by the fact that the upper, second section of these guideways is slightly funnel-shaped. Subsequently, the two drivers 2 to the middle of the drawer facing edge of the tracks of the control rails 10. Now you might think that thereby move the control rails 10 back towards the middle of the drawer. However, this is not possible because the free arms of the two rocker arms 22 (see Fig. 6 ) still rest against the last step of Verrastkontur 21 and can move out of this position only by a pivoting movement of the control rails 10 in the direction of the drawer side walls, but not in the direction of the middle of the drawer. The combination of one of the two rocker arms 22 and (one half) of the latching contour 21 in this situation thus in each case a latching mechanism 11 for the two control rails 10. By means of these Verrastmechanismen the position of the two control rails 10 with respect to the drawer 2 and of course the furniture body 6 at the beginning of the closing movement and thus also the starting point x _{i of} the charging path .DELTA.x, via which the loading of the energy storage device 4 is set. Characterized in that the control rails 10 are now fixed in position, the driver 7 and thus the energy storage 4 have no choice but to dodge in the direction of the drawer side walls and against the spring force of the torsion springs. In this way, a part of the energy of the translational movement of the drawer 2 is transmitted to the energy storage 4.

Another difference between the opening and closing movement of the drawer 2 is also that the driver 7 now along those sides of the move two pivoting lever 25, which are facing the drawer side walls, since these pivoting lever 25 are indeed pulled by the two small springs described above in the direction of the middle of the drawer and thus to an edge 32 of the control rail 10, so that the driver 7 is not in the first section of the guideways of the control rails 10 can move back. This fact is based on the enlarged section of the Fig. 11 recognizable. The end point x _{f of} the load path Δx, at which the two energy accumulators 4 are fully charged, is reached where the drivers 7 have reached the pivot point 26 of the two pivot levers 25 (see Fig. 10 ), ie that the end point x _{f of} the charging path .DELTA.x - regardless of Ausziehweg the drawer 2 - is located at a fixed relative to the furniture body 6 point. At this end point x _{f of} the charging path .DELTA.x the leg spring of the two power storage 4 is maximally tensioned. Up to this end point x _f , which is reached about 10 cm before reaching the closed position, the user must actively move the drawer 2. As soon as the end point x _{f is} exceeded, the two energy accumulators 4 relax (until they reach the closed position) slightly again. Due to the released energy, the drawer 2 is now automatically pulled into the closed position. The ejection devices 3 thus simultaneously act as intake devices. Important in this context is also that the arrangement 1 in the preferred embodiment shown here in each case comprises a damping device 13 for damping the retraction movement of the intake device 3. More specifically, it is a fluid damper in the form of a linear damper with a piston-cylinder unit, said damper device 13 is connected to the carcass rail of the extension guides 18 and the furniture body 6 and the piston of this damper 13 to a laterally disposed on the drawer rail 19 abuts and attenuated in this way the retraction movement. Alternative damper types, which are known from the prior art (eg rotary damper), are of course not excluded from the idea of the invention. Fig. 13 shows the closed position of the drawer 2, which already on the basis of Fig. 3 has been described.

Based on FIGS. 14 and 15 Let now be a closing movement from a middle, ie not fully open position of the drawer 2 illustrated, this middle position also represents a possible second open position of the drawer in the sense of claim 1, which is greater than the first open position represents. During the opening process engage the free arms of the two small rocker arms 22 (see Fig. 6 ), which are respectively arranged at the upper ends of the control rails 10, gradually at the stages of Verrastkontur 21st Fig. 14 shows a middle position of the drawer 2, in which the free arms of the two rocker arms 22 are located on the third stage of Verrastkontur 21. If you now want to close the drawer 2, so lock the two control rails 10 in these two positions and thus set the starting point x _{i of} the charging path .DELTA.x fixed. Comparing the Fig. 14 with the Fig. 10 Thus, it is found that the charging distance .DELTA.x on the one hand is much shorter and, on the other hand, that the angle of inclination of the control rails 10 with respect to the drawer side walls is greater. This must also be the case, since the same energy has to be transmitted for a complete charging of the energy storage device 4 over a shorter path, ie more force has to be applied by the user to close the drawer 2 or to load the energy storage device 4. Generally speaking, therefore, by changing the position of the control rails 10 with respect to the drawer 2 and the furniture body 6, the force expended for loading the energy storage device 4 adjustable.

In the Fig. 15 Once again the position of the drawer 2 is shown, in which the end point of the loading distance .DELTA.x were just exceeded by the drivers 7 of the energy storage 5 and a partial unloading of the energy storage 4 begins, which subsequently the drawer 2 is automatically pulled.
