Description

[Technical Field]

[0001] The invention relates to a synchronizing device having at least two drives for moving movable furniture parts and at least one synchronizing rod for synchronizing the movement of the at least two drives, a first end region of the synchronizing rod being connectable to a first rotating member of the first drive and a second end region of the synchronizing rod being connectable to a second rotating member of the second drive, and at least one length compensating device is provided which is able to at least partially compensate for play in the longitudinal direction of the synchronizing rod between the drives and the synchronizing rod in the assembled state of the synchronizing rod.

[0002] WO 2013 / 040611 discloses a synchronizing device with a synchronizing rod for synchronizing two drives. The purpose of such a synchronizing device is to ensure that the movable furniture part can always be guided at a uniform distance relative to the furniture cabinet, especially when the movable furniture part is operated by manually applying a force on one side. The synchronizing rod can be connected to both drives even when the drives are already pre-assembled to the furniture cabinet. A necessary condition for optimal synchronization is that the play occurring in the longitudinal direction of the synchronizing rod is compensated. For this purpose, at least one rotating element of the drive has a spring-like pressure contact that can contact the end face of the synchronizing rod, and this pressure contact allows the longitudinal play to be compensated. A disadvantage of this design is that the drive with the spring-like pressure contact has a relatively bulky construction.

[0003] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a synchronizer of the type mentioned at the outset which has a compact design.

[0004] This problem is solved according to the invention by the features of claim 1. Further advantageous embodiments of the invention are defined in the dependent claims.

[0005] According to the invention, it is envisaged that at least one of the drive units has a casing and that the length compensation device is integrated into the casing at least in a predetermined area and / or that the length compensation device is integrated into the synchronising rod at least in a predetermined area.

[0006] In other words, the length compensation device for compensating for the longitudinal play of the synchronizing rod is integrated into the drive casing and / or into the synchronizing rod itself, which allows for a more compact design of the drive and / or the synchronizing rod.

[0007] According to a preferred embodiment, the synchronization rod comprises: - the drive unit can be removably coupled to the rotary member of the drive unit, even if the drive unit is already pre-assembled, in particular in a furniture cabinet; and / or - connected to the rotary member of the drive device in such a way that it cannot rotate relative to the rotary member; and / or - the length compensator is preloaded by a predetermined holding force relative to the rotating members of the drive devices in the longitudinal direction of the synchronizing rod between the opposing rotating members of the drive devices, and / or the length compensator is held without play in the longitudinal direction of the synchronizing rod between the rotating members of the drive devices; and / or -Formed to be constant in length It may be assumed that.

[0008] In principle, synchronizers can be used wherever the rotational movements of two drives must be synchronized, i.e., for example, for the synchronous actuation of so-called touch-latch devices for releasing a movable furniture part from a closed end position. Such a touch-latch function allows the release of a movable furniture part by applying a manual pushing or pulling load to the furniture part in the closed position.

[0009] The synchronising device can also be used to synchronise the movement of movable furniture parts, in particular doors, flaps or drawers, or to synchronise the movement of other movable elements, for example windows.

[0010] Further details and advantages of the invention will become apparent from the following description of the drawings. [Brief explanation of the drawings]

[Figure 13]FIG. 12c shows an exploded view of the length compensation device according to FIGS. 12a and 12b.

[0012] Figure 1a shows a piece of furniture 1 comprising a furniture cabinet 2 and a movable furniture part 3 in the form of a flap 3a which is supported for movement relative to the furniture cabinet 2 via two drives 100, 200.

[0013] In Figure lb, the movable furniture part 3 has been omitted, so that the drives 100, 200 mounted on the opposite side walls are visible. Together with the synchronising rod 5, both drives 100, 200 form a synchronising device 6 for moving the movable furniture part 3.

[0014] In the illustrated embodiment, both drives 100, 200 each have at least one actuating arm 101, 201 which is preferably pivotable about a horizontal axis, and which actuating arm can be coupled to a movable furniture part 3.

[0015] One rotating member 102, 202 is operatively coupled to each of the actuating arms 101, 201; the rotating member 102 of the left drive 100 is not visible in the view shown in Fig. 1b. A synchronizing rod 5 formed as a torsion axis is provided to synchronize the movements of the two drives 100, 200, so that a coupled, synchronous rotational movement of the two rotating members 102, 202 of the two drives 100, 200 occurs. Of course, it is also possible for the rotating member 102, 202 to be formed by one of the actuating arms 101, 201.

[0016] Preferably, the synchronization rod 5 may be assumed to extend substantially horizontally in the assembled state.

[0017] 2a shows an embodiment of the synchronizer 6 in a perspective view. The drives 100, 200 each have a casing 103, 203 to be attached to the furniture cabinet 2 and at least one rotating element 102, 202 for removably connecting to the synchronization rod 5. The casing 103, 203 may be formed by at least two casing walls spaced apart from each other at least in a predetermined area. The synchronization rod 5, having a longitudinal direction L, is connected to the rotating elements 102, 202 of the drives 100, 200 in a non-rotatable manner in the connected state, so that when the rotating elements 102, 202 move, the synchronization rod 5 also moves.

[0018] According to one embodiment, at least one of the drives 100, 200 has at least one actuating arm 101 (Fig. 1b) rotatable about at least one first axis of rotation for moving the movably supported furniture part 3 relative to the casing 103, 203, the rotating member 102, 202 of the drive 100, 200 being arranged laterally offset with respect to the first axis of rotation of the actuating arm 101, 201.

[0019] Figure 2b shows an enlarged view of the circled area "B" in Figure 2a. In the illustrated embodiment, the rotating members 102, 202 are integrated into casings 103, 203, respectively, resulting in a very compact construction of the drive devices 100, 200.

[0020] 2c shows an embodiment of a rotating member 102 which is integrated, at least in certain areas, preferably substantially completely, into the casing 103 of the drive device 100. The rotating members 102, 202 each have an interface 10 for removably attaching a synchronization rod 5.

[0021] According to a possible embodiment, at least one of the rotating members 102, 202 has: - at least one tooth row 7, preferably with at least two toothed segments 7a, 7b, 7c, which are arranged in layers and in contact with one another in the longitudinal direction L of the synchronizing rod 5; and / or - supported on a shaft 8 in which a length compensation device 9 is integrated; and / or - integrated into the casing 103, 203 of the drive 100, 200; and / or - at least two components 8a, 8b which are movable relative to one another in the longitudinal direction L of the synchronization rod 5, preferably the components 8a, 8b being preloaded relative to one another by at least one energy accumulator 13 (Fig. 2d) and / or the components 8a, 8b being telescopically extendable relative to one another; It may be assumed that.

[0022] According to a possible embodiment, it may be provided that one of the at least two toothed segments 7a, 7b, 7c consists of a first material and the other toothed segment 7a, 7b, 7c consists of a second material having a lower hardness than the first material, preferably the first material being steel and / or the second material being plastic.

[0023] Figure 2d shows in cross section the rotary element 102 according to Figure 2c. It can be seen that the rotary element 102 has at least two components 8a, 8b which are slidable relative to one another and which are preloaded relative to one another by means of energy accumulators 13, preferably in the form of compression springs.

[0024] The component 8b is configured in such a way that the component 8b can be connected in a form-locking manner to the synchronizing rod 5, thereby forming a torque transmission between the rotating element 102 and the synchronizing rod 5. For this purpose, the rotating elements 102, 202 each have an interface 10 for detachably connecting the synchronizing rod 5.

[0025] According to another embodiment, it can be provided that at least two toothed segments 7a, 7b, 7c are arranged in layered contact with one another in the direction of the longitudinal axis L of the synchronizing rod 5, with one toothed segment 7b of the at least two toothed segments 7a, 7b, 7c protruding radially beyond another toothed segment 7a, 7c. In this way, play occurring between the rotating members 102, 202 and a transmission element (not shown) meshing with the rotating members 102, 202 can be reduced.

[0026] 3a shows a perspective view of a rotating element 102 with a length compensation device 9 integrated therein. A tooth row 7 can be seen, which comprises three toothed segments 7a, 7b, 7c that contact one another in layers. The outer toothed segments 7a, 7c can be made, for example, of metal, and the central toothed segment 7b can be made of plastic, which protrudes radially beyond the outer toothed segments 7a, 7c.

[0027] The rotating member 102 has an interface 10 for detachably coupling to the synchronization rod 5. According to a possible embodiment, the interface 10 comprises: the synchronization rod 5 is configured in such a way that it can be connected to the rotation element 102 in only one rotation position within a rotation angle range of 360°, and / or a connecting element 10a with an outer contour other than circular for receiving the synchronizing rod 5 in a form-locking manner, the outer contour preferably having a plurality of projections 11a, 11b, 11c, 11d arranged at substantially equal intervals in the direction of rotation in a predetermined section, and at least one flattened portion 12 or recess arranged in place of the projections 11a, 11b, 11c, 11d; Such a configuration makes it possible for the synchronization rod 5 to be connectable to the rotation member 102 in only one rotation position within a rotation angle range of 360°.

[0028] Figure 3b shows the rotary element 102 according to Figure 3a in a cross-sectional view. It can be seen that the components 8a and 8b are preloaded relative to one another by the energy accumulator 13, with the component 8b being in the extended position relative to the other component 8a. In this position, the maximum play of the synchronizer rod 5 relative to the rotary element 102 can be compensated for.

[0029] 3c shows the rotating element 102 with one component 8b in a run-in position relative to the other component 8a, i.e. in this position the play of the synchronizing rod 5 relative to the rotating element 102 can be compensated for to a minimum.

[0030] Figure 3d shows the rotary member 102 according to figure 3c in a cross-sectional view.

[0031] 4a shows a perspective view of the synchronizing rod 5 connected to the rotating member 102. It can be seen that the projections 11a, 11b of the component 8b formed as a connecting member 10a are form-lockingly engaged in the end region of the synchronizing rod 5.

[0032] The interface 10 may have an outer contour different from circular and may include a receiving portion 21 for form-lockingly receiving the connecting element 10a. In the illustrated embodiment, the receiving portion 21 is formed by the synchronizing rod 5.

[0033] Figure 4b shows a cross-sectional view of the synchronizing rod 5 and the rotating member 102 according to Figure 4a. The synchronizing rod 5 may have at least one cavity 23 in at least one of its end regions, and the length compensation device 9 is arranged in the cavity 23 at least in a predetermined section.

[0034] According to one embodiment, it can be assumed that the length compensation device 9 has at least one first energy accumulator 13 acting in the longitudinal direction L of the synchronization rod 5, which energy accumulator 13 is arranged in the hollow space 23 of the synchronization rod 5 at least in a certain section.

[0035] The synchronization rod 5 may have the same cross section over its entire length and / or may be formed as a hollow section with the same internal diameter over its entire length.

[0036] FIG. 5 a shows a perspective view of an embodiment of a synchronization rod 5 with a partially integrated length compensation device 9 for compensating for longitudinal play occurring in the longitudinal direction L of the synchronization rod 5 .

[0037] According to one embodiment, it may be envisaged that the length compensation device 9 is arranged on the synchronization rod 5 only in one end region.

[0038] In the region of the first end, the synchronizing rod 5 has a fixed outer contour 13 with a cross section that differs from circular, which can be connected in a form-locking manner to one of the rotating members 102, 202 of the drive device 100, 200.

[0039] The synchronizing rod 5 has, in its second end region, a length compensation device 9 with an interface 10 for detachably coupling to a rotating member 102, 202 of the drive device 100, 200. The interface 10 has a plurality of protrusions 11a, 11b, 11c, 11d arranged at substantially equal intervals in the direction of rotation and at least one flattened portion 12 or recess arranged in place of the protrusions 11a, 11b, 11c, 11d.

[0040] According to one embodiment, it may be provided that the length compensation device 9 is or can be coupled to the synchronization rod 5 in a frictionally coupled manner.

[0041] Figure 5b shows a length compensation device 9 according to figure 5a in a cross section.

[0042] The length compensation device 9 has at least one energy accumulator 13 acting in the longitudinal direction L of the synchronizing rod 5 and / or at least one spring element 16 acting transversely to the longitudinal direction L of the synchronizing rod 5, with the aid of the spring element 16 being able to compensate for play transverse to the longitudinal direction L of the synchronizing rod 5. The spring element 16 can be configured, for example, as a leaf spring.

[0043] The length compensation device 9 may have at least two connecting elements 8c, 8d which are supported for sliding, preferably limited, movement relative to one another in the longitudinal direction L of the synchronization rod 5. The connecting elements 8c, 8d are preloaded relative to one another by force accumulators 13, for example in the form of compression springs.

[0044] In this embodiment, the length compensation device 9 has at least one pivot lever 14, which is supported so as to be pivotable between a release position and a lock position about a pivot axis 15 transverse to the longitudinal direction L of the synchronization rod 5.

[0045] The pivot lever 14 has a projection 17 which can be pressed against the spring element 16 and thus against the component 8c by manipulating the pivot lever 14 about the pivot axis 15. In this way, the relative position of the two slidable connecting parts 8c, 8d of the length compensation device 9 can be locked. The spring element 16 is supported on the pivot lever 14 at least in the locked position of the pivot lever 14.

The two connecting parts 8c, 8d are preloaded relative to one another by a force accumulator 13, so that the longitudinal play occurring in the synchronizer rod 5 relative to the rotating parts 102, 202 of the two drives 100, 200 can be compensated. Furthermore, at least one additional spring element 16 is provided, which can compensate for the play occurring between the two connecting parts 8c, 8d transverse to the longitudinal direction L.

By movement of the pivot lever 14 about the pivot axis 15, the spring element 16 can be pressed by the projection 17 against the inner connecting part 8d, in which case the relative position between the connecting parts 8c, 8d can be locked.
