    The invention relates to a synchronization device for a movably mounted furniture part, wherein the synchronization device synchronizes a movement between at least two adjusting devices via a synchronization rod.
    Furthermore, the invention relates to a coupling for an overload protection device, with a torque transmitting shaft, wherein the overload protection device between two part waves of the shaft is arranged.
    Furthermore, the invention relates to a movably mounted furniture part with a synchronization device and / or a coupling as just mentioned. Likewise, the invention relates to a piece of furniture with a movably mounted furniture part as mentioned.
    Synchronization devices for movably mounted furniture parts are already known in a variety of the prior art. In essence, there are three different areas of application for movably mounted furniture parts: - the synchronization of drawer pull-outs from a drawer - the synchronization of the actuators of a furniture flap - the synchronization of lockable and unlockable ejection devices of movably mounted furniture parts.
    For example, EP 1 036 526 B1 of August 24, 2005, shows a drawer with a device for stabilizing the running behavior of the drawer, the drawer being movable in a furniture carcass and having drawer frames, a toothed wheel being provided on each side of the drawer, each meshing with a body-side rack and the two gears that are rotatably connected to each other, store in Lagererkörpem.
    The EP 1 875 026 B1 of October 13, 2010 shows a cabinet-shaped furniture with side walls, on each of which an adjusting device with at least one pivotally mounted actuating arm for moving a flap is arranged, wherein the adjusting devices are connected by a synchronization rod for synchronous movement thereof.
    WO 2010/129971 A1 of 18 November 2010 shows an arrangement for locking and ejecting a movable furniture part with two arranged on both sides of a furniture body or on the movable furniture part, unlockable ejection devices, wherein the unlockable ejection devices are coupled in motion via a rotatable synchronization rod.
    The object of the invention is to provide a comparison with the prior art improved synchronization device for a movably mounted furniture part.
    This object is achieved with the features of claim 1.
    By using an overload protection device, which is released when a predetermined holding torque between the two partial waves of the synchronization device relative rotational movement between the two partial waves, damage to the movably mounted furniture part can be prevented.
    Further advantageous embodiments of the invention are defined in the dependent claims.
    To be particularly advantageous, it has been found that the overload protection device has at least one radially or axially spring-loaded locking part, which engages in at least one of the two sub-waves - preferably in both sub-waves - and at least one of the two sub-waves - preferably in both sub-waves - locks. By using a spring-loaded locking part, a connection between the overload protection device and the partial waves can be achieved in a simple manner.
    According to a preferred embodiment it can be provided that the two partial shafts plug into each other and the spring-loaded locking part of the 3 overload protection device is formed radially to the two partial shafts, wherein the spring-loaded locking part penetrates a partial shaft and engages in the other partial shaft. By means of two sub-shafts which are inserted into one another, the spring-loaded detent part can connect both partial shafts to one another.
    Furthermore, it can preferably be provided that the overload protection device is designed as a resilient sleeve and has at least one radially inwardly directed latching nose, which engages in at least one of the two partial shafts - preferably in both partial shafts -. A designed as a resilient sleeve overload protection device can engage around the two partial shafts and by the radially inwardly directed locking lug fixed in the partial waves a snap.
    It has proved to be particularly advantageous if the overload protection device is formed in one piece and / or that the overload protection device is made of plastic and / or that the overload protection device can be removed without tools and / or removed without tools. This can contribute to short assembly times being able to be achieved.
    Protection is also desired for a clutch for an overload protection device, in particular for a synchronization device according to at least one of the described embodiments, with a torque transmitting shaft, wherein the overload protection device is arranged between two partial shafts of the shaft.
    It has proven to be particularly advantageous when the locking part of the resilient sleeve is designed as a latching lug and the counter-latching is formed as a recess - preferably as a blind hole.
    According to a preferred embodiment it can be provided that the disengaged latching part of the resilient sleeve automatically engages in the counter-latching of the other partial shaft again. Thus, no action from the outside is necessary - such as by the operator to restore the connection via the clutch.
    Protection is also desired for a movably mounted furniture part with a synchronization device and / or a coupling according to at least one of the described embodiments.
    Specifically, protection is desired for a piece of furniture with a movably mounted furniture part with a synchronization device and / or a coupling according to at least one of the described embodiments.

    FIG. 1a shows a perspective view of a piece of furniture 210 with a movably mounted furniture part 200, which in this embodiment is designed as a drawer 201. The drawer 201 is movably mounted in the furniture body 209. About the synchronization device 100, the adjusting devices 102 and 103 (103 not shown, see Figure 2) synchronized, which in this embodiment as
    Drawer extension guides 110 and 111 (111 not shown, see Figure 2) are formed. At the synchronization device 100, the overload protection device 1 is provided. The overload protection device 1 is formed on the torque transmitting shaft 51, which acts as a synchronization rod 101 in this embodiment. The overload protection device 1 or the coupling 50 acts in this case between the two partial waves (not shown) of the period 51 (partial waves, see FIG. 3).
    FIG. 1b shows a piece of furniture 210 with a furniture flap 202. The furniture flap 202 is moved via two adjusting devices 102 and 103 (103 not shown), which in this embodiment are designed as actuators 120 for the furniture flap 202. The two actuators 120 (only one shown) are connected to each other via the synchronization device 100 and are synchronized via this, furthermore, the synchronization device 100 has an overload protection device 1, not shown here, which upon exceeding a predetermined holding torque relative rotational movement between the two actuators 102 and 103 releases and thus can prevent damage to the actuators 120.
    FIG. 1 c shows a piece of furniture 210 with a furniture body 209, with a plurality of movably mounted furniture parts 200 - in this embodiment designed as drawers 201. The adjusting devices 102 and 103 (103 not shown) are formed in this embodiment as lockable and unlockable ejection devices 130 for the movably mounted furniture part 200. The synchronization device 100 acts between the lockable and unlockable ejection devices 130. Furthermore, the synchronization device 100 has an overload protection device 1 (not shown here).
    Figure 2 shows a bottom view of a piece of furniture 210. The furniture 210 has a movably mounted furniture part 200, which is formed in this embodiment as a drawer 201. The synchronization device 100 for the movably mounted furniture part 200 is located on the rear side of the drawer, the synchronization device 100 synchronizing a movement between the two adjusting devices 102 and 103 via the synchronization rod 101, wherein the synchronization rod 101 has two partial shafts 10 and 20, between which an overload protection device 1 is arranged, which releases a relative rotational movement between the two partial shafts 10 and 20 when a predetermined holding torque between the two partial shafts 10 and 20 is exceeded.
    Left and right, the synchronization device 100 each have a gear 104 (not shown, see Figure 3). The gears 104 each engage the racks 106 on the left and right (also not shown, see FIG. 3).
    The synchronization device 100 serves to synchronize the actuators 102 and 103 - in this drawer 201 as drawer extension guides 110 and 111 - synchronized. By a possible misuse of a user - as shown in this figure - it may occur that the drawer 201 is inclined to the furniture body 209 (for example, by one-sided loading of the drawer 201). If the drawer 201 were subsequently pushed further into the furniture carcass 209 on its position not yet in the end position, the synchronization device 100 could be damaged. For this reason, the synchronization device 100 has the overload protection device 1, which releases a relative rotational movement between the two partial shafts 10 and 20 when a predetermined holding torque between the two partial shafts 10 and 20 of the shaft 51 or the synchronization rod 101 is exceeded.
    In this preferred embodiment, the overload protection device 1 has a coupling 50, which is designed as a collar 3 (not shown, see Figures 3 to 7).
    FIG. 3 shows a perspective rear view of a detail of a drawer 201.
    The drawer 201 can be moved via the drawer pull-out guide 110. For synchronization purposes between the left and right drawer pull-out guides 110 and 111 (not shown), the synchronization device 100 is provided, which in this preferred embodiment is provided with a sleeve-shaped overload safety device 1.
    The operation of the overload protection device 1 will be explained in more detail in the following description of the figures.
    The synchronization device 100 drives in this embodiment, a gear 104, on the opposite side of the shaft 51 and the synchronization rod 101 also not shown another gear.
    These two gears 104 engage with the racks 106 and move into them. The gears 104 together with the racks 106, the adjusting devices 102 and 103 (not shown, see Figure 2).
    The two partial shafts 10 and 20 of the synchronization rod 101 and the shaft 51 are inserted into one another in this preferred embodiment and are radially penetrated by the coupling 3 or a locking part of the coupling 3 or penetrated into the inner part shaft 20 (see FIGS. 5a and 5b) 6a).
    Of course, a synchronization device 100 shown here is conceivable not only for a drawer 201, but also for any other movably mounted furniture part 200, such as the actuators of a furniture flap 202, not shown here, or also for a ver and unlockable ejection device not shown here for movably mounted Furniture parts 200 (see Figures 1 a to 1 c and their description).
    FIG. 4 shows a perspective exploded view of the two partial shafts 10 and 20 and the overload safety device 1, or the coupling 50.
    The overload protection device 1 in this case has the coupling 50, which in turn is designed as a resilient sleeve 3. The resilient sleeve 3 has the spring-loaded locking part 2, which is formed in this preferred embodiment as a locking lug 4, which is directed radially inward. This radially inwardly directed locking lug 4 passes through the opening 11 of the partial shaft 10 and then penetrates into the counter-latching 21 of the partial shaft 20 and lingers in this until it exceeds a predetermined torque. The counter-latching 21 is formed in this preferred embodiment as a recess 22, strictly speaking as a blind hole 9, 9. The exact mode of operation is explained in more detail in FIGS. 5a and 5b. The overload protection device 1 here also has a radially inwardly directed web 61, which penetrates the opening 62 of the partial shaft 10 and lingers in the radially formed groove 60 of the partial shaft 20. As a result, the position of the partial shaft 20 is determined to the partial shaft 10, both in non-activated overload protection device 1 and activated. As a result, the two partial shafts 10 and 20 remain connected to each other, even if the coupling 50 opens, since only the resilient locking part 2 of the coupling 50 disengages from the partial shaft 20, but not the web 61 (see Figure 5b).
    FIGS. 5a and 5b show two sectional views through the two partial shafts 10 and 20 and the overload safety device 1, which has the coupling 50 in this preferred exemplary embodiment.
    The two partial shafts 10 and 20 are inserted into one another in this exemplary embodiment, that is to say that the partial shaft 20 is located partly in the interior of the partial shaft 10. The sleeve 3 designed as a coupling 50 surrounds the partial shaft 10 and penetrates the partial shaft 10 through the opening 11, in fact penetrates the locking part 2, which is designed as a latching lug 4, this opening 11 of the partial shaft 10th
    When the coupling of the two partial shafts 10 and 20 is made, so the locking lug 4 stored in the counter-detent 21 of the partial shaft 20th
    If a predetermined torque between the two partial shafts 10 and 20 is exceeded, then the locking lug 4 locks out of the counter catch 21, which is designed as a blind hole 23, and the partial shaft 20 can rotate relative to the partial shaft 10. During this twisting latches the locking lug 4 in the opening 11 of the part shaft 10 and "waits" for the two partial shafts 10 and 20 align again against each other, whereupon the locking lug 4 engages completely automatically in the blind hole 23 again. In order for the two partial shafts 10 and 20 not to be able to separate from one another during the "disengaged" state of the coupling 50 from the blind hole 23 of the partial shaft 20, the female connector 10
    Synchronization device in addition to a holding device, which holds the two partial shafts 10 and 20 together (see Figures 6a and 6b). This holding device is formed in this preferred embodiment of the coupling 50 and the overload protection device 1 - at least partially.
    Figure 6a and Figure 6b show a perspective section through which the two partial shafts 10 and 20 and the overload protection device 1 and the clutch 50 in the locked state (Figure 6a) and in the unlatched state (Figure 6b). Regarding the function of the overload protection device 1 or the coupling 50, the same applies with regard to FIG. 5a and FIG. 5b. In these Figures 6a and 6b, the holding device is well recognizable, which is formed by the radially extending groove 60 of the partial shaft 20, the web 61 of the overload protection device 1 and the opening 62 (not shown, see Figure 4) of the partial shaft 10. Even with activated overload protection device 1 or dissolved clutch 50 (Figure 6b), the web 61 dwells in the groove 60 of the partial shaft 20, whereby the partial shaft 20 can rotate relative to the partial shaft 10, but these can not be separated from each other.
    Figure 7a and Figure 7b show a perspective view of the two partial shafts 10 and 20 with the overload protection device 1, which is designed here as a coupling 50.
    In Figure 7a, the clutch 50 is engaged, in Figure 7b, the clutch 50 is disengaged, ie, that the locking member 2, strictly speaking the locking lug 4, is no longer in the counter-latching 21, not shown, and thus the two partial shafts 10 and 20 against each other can be rotated, which automatically takes place when exceeding a predetermined torque. Likewise automatically or automatically engages the locking lug 4 again in the partial shaft 20, if this is in turn with its counter-detent 21 at the locking lug 4.
    FIGS. 8a to 11b show various embodiments of an overload protection device 1 or a coupling 50 for a torque-transmitting shaft 51 and its two partial shafts 10 and 20, and will now be explained in more detail:
    Figures 8a and 8b show the two partial shafts 10 and 20 of the torque transmitting shaft 51, wherein in the partial shaft 20 of the spring-loaded locking part 2 is formed, which engages in a counter-latching 21 of the partial shaft 10.
    In Figure 9a and Figure 9b, the spring-loaded locking part 2 is formed in the partial shaft 10 and engages spring loaded in the counter-latching 21 of the partial shaft 20 a.
    In FIGS. 10a and 10b, the two partial shafts 10 and 20 are not inserted into one another, but rest on one another at their end faces. The two spring-loaded locking parts 2 are formed in this embodiment in the coupling 50 and protrude into the counter-latches 21 of the two partial shafts 10 and 20 inside.
    In Figures 11a and 11b, the overload protection device 1 is formed axially to the two partial shafts 10 and 20, wherein the spring-loaded locking part 2 of the one part shaft 20 engages in the counter-latching 21 of the other part shaft 10.
    It goes without saying that both the spring-loaded locking part 2 and the counter-latching 21 can also be formed on the other partial shaft 10 and 20, respectively. Of course, this also applies to all other mentioned embodiments.
    FIG. 12 shows a schematic representation of a drive 70 which drives a torque-transmitting shaft 51. As a result, the torque transmitting shaft 51 transmits a torque to the output 71.
    The shaft 51 has in this case the two partial shafts 10 and 20, between these two partial shafts 10 and 20, the coupling 50 is designed as an overload protection device 1, wherein the coupling 50 is a resilient φ · · »« φ «4 · # ··« · • · > »Ψ» * * «♦ ** • φ Φ φ · · * * # ♦ φ Φ Μ · suffered« | 12
    Cuff 3 has, which is mounted on one of the two partial shafts 10 and 20 and which carries a locking part 2 (not shown, see Figure 5a), the latching in a counter 21 (not shown, see Figure 5b) of the other part shaft 10 and 20 engages and automatically disengages when a predetermined holding torque is exceeded and releases a relative rotational movement between the two partial shafts 10 and 20.
    FIG. 13 shows a perspective exploded view of the two partial shafts 10 and 20 with an overload safety device 1, which in this preferred exemplary embodiment is designed as a sleeve 3 or has such a sleeve. In a preferred embodiment, this sleeve 3 is formed of plastic and further in one piece. This allows a quick mounting. The mounting itself can be done completely without tools, since the cuff 3 simply needs to be clipped.
    In order to increase the stability of this plastic sleeve 3, a spring steel sleeve 30 may additionally be provided in this preferred embodiment, which is also preferably clipped over the sleeve 3.
