Description

photoshoot AT506 642B1 2014-03-15

The present invention relates to an actuating arrangement with two adjusting devices, each having at least one actuator for moving a movably mounted in or on the furniture body furniture part, wherein the adjusting devices are mounted on a furniture body and the actuators via a synchronization rod for synchronous movement of Actuators are connected, wherein the connected via the synchronization rod actuators without removing the synchronization rod are rotatable relative to each other and fixed in a twisted position to change the relative position of the movable furniture part to the furniture body.

Stellanordnungen with such adjusting devices are preferably used to move flaps or lifting doors of furniture, in particular of upper cabinets, but also of drawers, from a closed to an open position and vice versa. In order to cope with the forces occurring during this movement, such adjusting arrangements have two adjusting devices, which are arranged, for example, in the case of a cupboard-shaped furniture on the side walls. In order to enable a stiffening of the two adjusting devices to each other and a synchronous movement of the two adjusting devices and, consequently, a uniform movement of the moving furniture part, WO 2006/113953 A1 provides a transversely extending synchronization rod which connects two actuators of the adjusting devices together and in a practical manner is formed such that the synchronization rod is also connectable to the actuator when the actuator is already pre-assembled on a side wall of the furniture.

When mounting the adjusting devices, it may now come due to tolerances in the production or due to small installation errors for bracing the front of the furniture part, such as the flap of a cupboard-shaped furniture, whereby this no longer rests evenly on both sides of the body and an unclean joint appears.

In the US 2004/0252045 A1 a cabinet furniture is shown, which has an electric opening mechanism with which two concealed hinges can be opened independently. To synchronize the opening movement, a shaft-like connecting element is provided, which is mounted on a mounting plate of the hinge. The mounting plate in turn is mounted on a carriage of a rail system. In order to move the relative position of the two mounting plates to each other linearly, different holes for adjusting screws are arranged on the mounting plate.

The AT 6529 U1 discloses an actuating arrangement, wherein two arranged on the drawer bottom ejection lever together with each one arranged on the body stop member form a touch-latch mechanism. The two ejection levers are coupled together via two connecting rods. The ejection lever itself may be formed in two parts, wherein the angle between the two parts is adjustable.

The European patent application EP 1 479 866 A1 describes a flap for a furniture body, wherein the furniture fittings are mounted on the outside of the body. Two damping elements provided for damping, as well as two support arms are connected to one another with a brace. The damping element is operable with a lever having a recess for receiving the strut, which may be formed as a rod has. The lever can be adjusted angularly relative to the support arm, whereby two existing to open the door motors can be adjusted.

Further actuating arrangements, consisting of two locking devices connected to a synchronization rod, are shown in EP 1 925 770 A2 and JP 10151027 A.

Object of the present invention is to perform the adjusting devices and the synchronization rod such that after installation of the adjusting devices and the synchronization rod and without removing the same adjustment for correction die- 1/19

ikiirrek & ise-ts päiiisaret AT506 642B1 2014-03-15 ses unclean grout image exists.

This is inventively achieved in that the synchronization rod is designed at least in two parts and at least two parts of the synchronization rod are rotatable relative to each other and can be fixed in a twisted position.

By an embodiment of the adjusting devices and the synchronization rod according to the invention, therefore, the actuators can be adjusted relative to each other, whereby, for example, the joint is enlarged or reduced on one side of the movable furniture part and thus creates a uniform joint pattern and the tension of the front is resolved. The inventive possibility of fixing the actuators in the adjusted position, it is possible that the thus balanced joint image is maintained in the future.

The synchronization rod is designed in two or more parts, wherein the parts of the synchronization rod are rotatable relative to each other about its longitudinal axis and can be fixed in a rotated position. Due to the fact that the synchronization rod itself is connected at its two ends to the actuators, a rotation of the parts of the synchronization rod is transmitted to the actuators, whereby they move relative to each other. By fixing the parts of the synchronization rod in a twisted position, the actuators are fixed in an adjusted position. In a first embodiment, it is now provided that the multi-part synchronization rod, at least on parts of its lateral surface, preferably in the region where in each case adjoin two parts of the synchronization rod, has a longitudinal toothing. It may be provided that the cross-sectional areas of the parts of the synchronization rod, which meet one another, are made essentially planar. As a result, a rotation of adjacent parts of the synchronization rod is easily possible. Now, if a sliding sleeve with appropriate dimensions pushed onto the synchronization rod and has the sliding sleeve on an internal toothing, which preferably represents the counterpart of the longitudinal teeth of the parts of the synchronization rod, so the twisted parts of the synchronization rod in any position by this toothing and the corresponding internal toothing of the sliding sleeve be fixed.

In another embodiment of the invention, it is contemplated that two adjacent ends of the multi-part synchronization rod are formed such that at the adjacent ends of a worm wheel and a spindle are arranged and by turning the spindle, the two adjacent parts of the Synchronization rod can rotate relative to each other about its longitudinal axis. After completion of the turning operation of the spindle, the two parts of the synchronization rod are fixed in a rotated position.

In a further embodiment of the invention, it is provided that the synchronization rod is made of several parts, wherein at adjoining ends of the synchronization rod each an adjusting screw can be arranged, wherein by oppositely rotating the screws, the two adjacent parts of the synchronization rod relative to each other about its longitudinal axis are rotatable. If the direction of rotation of both screws is changed, the direction of rotation of the two parts of the synchronization rod to each other changes. After completion of the turning operation of the adjusting screws, the two parts are fixed in the twisted position due to the two setscrews. Axial fixation can be accomplished, for example, by a pin located at one of the ends of the parts of the synchronization rod and guided into a corresponding hole located at the adjacent end.

In one embodiment, the adjusting arrangement according to the invention for moving a furniture flap of an example cabinet-shaped piece of furniture with side walls, on each of which one of the adjusting devices is mounted, used. In this case, the adjusting device has a pivotally mounted actuating arm, on which the furniture flap is hinged, whereby it is possible that the furniture flap between a cupboard compartment in a furniture body 2/19

tewichischis AT506 642B1 2014-03-15 closing vertical position and an upwardly moved open position is adjusted. In this case, the actuator has a rotatable member with which a synchronization rod according to the invention is connected, whereby the rod rotates during its own axis during a movement process. Due to the relative adjustment of the actuators to one another, it is now possible according to the invention to relax due to slightly inaccurate mounted adjusting devices or because of fault tolerances strained front and produce a clean and uniform joint pattern.

In a further embodiment of the invention, the adjusting devices are realized by ejector and the associated actuators by ejection lever, which serve, for example, a drawer, which is movably mounted in a furniture body to eject from its closed end position. In order to avoid the disadvantage of an unfavorable exertion of a force acting centrally on the drawer rear wall ejection lever and an economically disadvantageous arrangement of two ejectors, which are both driven by a drive unit itself, it is provided that two ejectors with ejection levers apply the force on the edge of the movable furniture part and the two ejection levers are mechanically coupled preferably via a rod so that only one of the ejectors must be driven by a drive unit. Such ejectors are known for example from the Austrian patent application A 240/2007. Also in this embodiment, minor installation errors may occur or may be due to manufacturing tolerances inequalities in the mounted ejection levers or in the assembled movable furniture part, and thus an unclean joint pattern arise. By an inventive design of the adjusting devices with the synchronization rod between the ejection levers such errors can be repaired by adjusting the ejection lever relative to each other and fixing the ejection lever in an adjusted position. In this case, the synchronization rod for adjusting and fixing must not be removed.

In a further embodiment of the invention can be provided that the drive unit is in constant communication with the movable furniture part. Such an arrangement is known for example from EP 1 374 732 A1. It may be advantageous to attach the drive unit, which is part of an adjusting device, only on one side of the movable furniture part and to arrange a gear or a roller on the opposite adjusting device. The mechanical connection to the power transmission and the synchronization of the movement can be done by a synchronization rod. Due to an embodiment of the synchronization rod according to the invention, the two actuators of the respective positioning arrangements with which the synchronization rod is connected can be adjusted relative to each other without removing the synchronization rod and fixed in an adjusted position in order to repair minor installation errors or the like.

Furthermore, it is advantageous that the adjusting devices are mounted on the furniture body before the synchronization rod itself is mounted. As a result, further minor installation errors of the adjusting devices and other installation tolerances can be compensated. It may be advantageous that the synchronization rod is detachably connected at one end to the actuator of the adjusting device or it may be advantageous that both ends of the synchronization rod are detachably connectable to an actuator of the respective adjusting device. Furthermore, it may be advantageous that a longitudinal adjustment of the synchronization rod is provided, whereby it can be used in different furniture with different body width.

Connection stands.

Fig. 3a shows a perspective view of one of two parts 6 ', 6 " FIG. 3b shows a detailed view of the section marked N in FIG. 3a, wherein FIG. 3b shows no sliding sleeve 7. Along part of the lateral surface of the adjoining parts 6 ', 6 " the synchronization rod 6 is a spline 13, 13 'attached. The cross-sectional areas of the adjacent parts 6 ', 6 " are kept planar. This allows the two parts 6 ', 6 " the synchronization rod 6 are easily rotated relative to each other. The sliding sleeve 7 has at least on parts of its inner side to the longitudinal teeth 13, 13 'matching internal toothing 14, whereby the two parts 6', 6 " the synchronization rod 6 are fixed in a twisted position.

4a to 4h shows a particularly advantageous embodiment of the synchronization rod 6 according to the invention. Again, this consists of two parts 6 ', 6 ", which are rotatable relative to each other and the fixation via a sliding sliding sleeve 7. In the here illustrated embodiment, the internal teeth 14 of the sliding sleeve 7 extends only over half of its inner surface. In Fig. 4a is a side view of the synchronization rod 6 and a sliding sleeve 7 is shown. In the associated sectional view along the axis AA, which is shown in Fig. 4b and there B marked section, which is shown in detail in Fig. 4e, it can be seen that the internal teeth 14 of the sliding sleeve 7 by moving the sliding sleeve 7 to the right was displaced beyond the spline 13 of the part 6 ', so that a slight mutual rotation of the synchronization rod parts 6' and 6 " is possible. In this case, further stops and stop lugs can be provided on the sliding sleeve 7 or synchronization rod 6, so that only a limited displacement of the sliding sleeve 7 is possible. If the sliding sleeve 7 is shifted to the left again, as can be seen in FIG. 4c and the sectional view along the axis CC in FIG. 4d and in the detail view of the section marked D, the teeth of the longitudinal teeth 13 and 13 'and the matching one engage Internal gear 14 into each other, so that a mutual rotation of the parts 6 ', 6 " the synchronization rod 6 is no longer possible. FIG. 4g shows a sectional view along the axis E-E from FIG. 4c in the fixed position. In this case, and in the detail view of the section marked F in FIG. 4h, it can be seen how the teeth of the internal toothing 14 of the sliding sleeve 7 as well as of the longitudinal toothing 13, 13 'of the synchronization rod parts 6' and 6 " mesh.

Fig. 5a shows a perspective view of another embodiment of the synchronization rod 6 according to the invention. Again, this is made in two parts, the two parts 6 ', 6 " rotatable relative to each other and are fixable in a twisted position. In this embodiment, a short cylindrical piece 29 is arranged on a part 6 'of the synchronization rod 6, which has a smaller diameter than the part 6' of the synchronization rod 6 and a worm wheel 11. The adjacent part 6 " the synchronization rod 6 has a hole 31 into which the cylindrical piece 29 together with the worm wheel 11 can be inserted. In another hole 30, a spindle 12 can be introduced, which makes it possible to rotate the worm wheel 11, which is fixedly connected to the part 6 'of the synchronization rod 6, and to fix in a twisted position.

In Fig. 6a is a side view of this embodiment of the synchronization rod 6 according to the invention is shown. In the sectional view along the axis G-G of Fig. 6a, which is shown in Fig. 6b, it can be seen clearly how the thread of the spindle 12 in the course of the worm wheel 11, which in the hole 31 of the part 6 " the synchronization rod 6 is engaged and thereby causes a rotational movement of the spindle 12 and a rotational movement of the worm wheel 11.

Fig. 7a shows a perspective view of another embodiment of the synchronization rod 6 according to the invention. As can be seen in the exploded view of Fig. 7b, the part 6 " via a groove with subsequent hole 26, which is extended in the longitudinal direction of the synchronization rod 6, and a web 36, wherein the adjacent part 5/19 istefreidiiscises jafsüö with AT506 642 B1 2014-03-15 6 'of the synchronization rod 6 a suitable for curving the groove Buckle and a diameter of the hole 26 matching pin 32 and a web 27 has. In this case, an adjusting screw 15 is inserted into a corresponding hole 33 in the web 27 and a further adjusting screw 34 in a corresponding hole 35 in the web 36. The axial fixation is effected by the pin 32, which is guided in the corresponding hole 26.

As shown in the side view in Fig. 8a of this embodiment of the synchronization rod 6 according to the invention and the sectional view taken along the axis LL of Fig. 8a in Fig. 8b, a screwing in the screw 15 and unscrewing causes adjustment screw 34, that the curvature and the pin 32 of the part 6 'of the synchronization rod 6 in the groove and in the hole 26 of the adjacent part 6 " the synchronization rod 6 rotates and relative rotation of the two parts 6 ', 6 " the synchronization rod 6 allows. After completion of the turning operation of the adjusting screws 15, 34, the adjacent parts 6 ', 6 " the synchronization rod 6 no longer rotatable relative to each other and thus fixed in the rotated position. A reversal of the direction of rotation of the adjusting screws 15, 34 also changes the direction of the relative rotation of the two parts 6 ', 6 ".

In Fig. 9a and the detail view in Fig. 9b, a further embodiment of an actuating arrangement according to the invention is shown. The synchronization rod 6 has an interface which has a spline 13 and a part 6 " the synchronization rod 6 arranged longitudinal toothing 13 'has, whose profile with the longitudinal teeth 13 substantially coincides. The part 6 " having the spline 13 " forms a part of the synchronization rod 6, which is connected to the arranged on the actuating arm 8 rotatable member 19 via the fastening device 18. A sliding sleeve 7 with internal teeth serves to connect the two parts 6 'and 6 " the synchronization rod 6, the synchronization rod 6 or its part 6 " can be connected in rotation with the actuating arm 8 via the fastening device 18. Further actuating arms 8 'and intermediate lever 9 and flap-side fitting 10 transmit the movement to the flap. 5

In Fig. 10a to Fig. 10c is clearly the effect of the invention in the case of a cabinet-shaped piece of furniture 1 can be seen. Due to possible low manufacturing tolerances and minor installation errors, it can occur that the joint image between a flap 5 and a cabinet lid 3 is uneven, as shown in Fig. 10a and Fig. 10b. The effect of an actuating arrangement according to the invention by relative adjustment of the actuators and fixing in an adjusted position can be seen with reference to FIG. 10c. Due to the relative adjustment of the actuators on both sides of the cupboard-shaped furniture 1 creates a uniform joint pattern.

A further embodiment of an actuating arrangement according to the invention is shown in Fig. 11, where a furniture 20 is shown with partially removed lid having three movably mounted furniture parts 21, which are formed in this embodiment as drawers. However, the invention can also be used in furniture parts 21 designed as furniture doors. A carcass rail 25 and a non-recognizable in this figure drawer rail allow the movement of the movable furniture part 21, which by two ejectors 22 and 23, of which in this figure only one can be seen, is initiated. The details of the ejectors, which have ejection levers which serve as actuators, are not essential to the present invention and are, for example, in the Austrian patent application AT 504509 A4 explained in more detail. However, in order to drive only one of the ejectors 22 and 23, it is necessary to couple the two ejectors 22 and 23 mechanically, which in this case is realized by a two-part synchronizing rod 6. The synchronization rod 6 is designed according to the invention such that the two parts 6 ', 6 " can be rotated relative to each other and can be fixed in a twisted position, for example with a sliding sleeve 7.

In Fig. 12, the body rails 24 and 25 and a drawer rail 28 and the two ejectors 22 and 23 can be seen. Furthermore, a middle rail can be arranged on the carcass rail 25. The ejectors 22 and 23 are on the two-piece synchronizing executed 6/19

On the one hand, it is connected to the other. The relative rotation of the two parts 6 'and 6 " and their fixation in a twisted position is made possible by a sliding sleeve 7. Preferably, in this case, a longitudinal toothing 13, 13 'on parts of the lateral surface of the synchronization rod parts 6' and 6 " and a corresponding internal toothing 14 is used on the sliding sleeve 7. Nevertheless, it is conceivable, without departing from the essence of the invention, to realize other possibilities for relative rotation and fixation in a rotated position, for example by means of an arrangement with worm wheel 11 and spindle 12 or set screw 15.

The present invention is not limited to the embodiments shown but includes and extends to all variants and technical equivalents that may fall within the scope of the following claims. Also, the location information chosen in the description, such as up, down, etc. based on the usual installation position of the adjusting device 4 and on the immediately described and illustrated figure and are to be transferred to a new position analogously to the new situation. 7.19
