  The object of the present invention is to solve this problem in the prior art.

  The object is to provide a drive system that uses hinges with hinge cups and hinge arms to open and / or close furniture parts that are pivotable relative to each other, in particular double doors fastened to the body of the furniture part. In this drive system, the electric drive is formed as a confined component, the electric drive comprising an electric motor and an operating device for transmitting force or torque from the electric motor to the hinge. The operating device has a fixing portion, and the operating device can be releasably connected to the hinge by the fixing portion.

  As a result, even when the hinge is already attached to the furniture body, i.e., a plurality of furniture parts that are relatively pivotally connected to each other, the drive system is applied to the hinge that exists as a confined component unit. Can be fixed. Thereby, it is possible to replace the failed electric drive unit without removing the hinge itself from the furniture portion. Here, the hinge does not need to be disassembled, either for manufacturing or, if necessary, for releasing the connection with the operating device. Similarly, this type of retrofit is possible without having to change the hinge itself, for example by incorporating a new member. On the manufacturer side, the drive system of the present invention can be retrofitted to this hinge with only a slight modification of a general hinge, where the fixed part is formed without requiring any change of the hinge. It is also possible. Here, the drive system may include a power feeding device, a device that fixes the drive system to one of the furniture parts, an electric drive unit, and an operation device.

  At a later point in time, the fixing device, which can be releasably connected with the hinge, allows the existing hinge assembly, i.e. the furniture part pivotally connected by a hinge with a hinge cup and hinge arm, to be connected at a later time. A seed drive system can be retrofitted, where this retrofit can already be done in the factory. When the drive system is already installed on the factory side, the existing production line can be maintained, so installation of the drive system requires very little cost. Of course, the end consumer can also retrofit and / or remove the drive system from an existing hinge assembly.

  Further embodiments of the invention are defined in the dependent claims.

  In a preferred embodiment of the present invention, the operating device can be releasably connected to the hinge without disassembling the hinge. Here, even when the hinge arm of the hinge is connected to the hinge cup via at least one segment lever, the operating device can be provided to be releasably connected to the hinge.

  In a preferred embodiment of the invention, the operating device can be attached to the hinge without a tool and / or can be removed without a tool. This can be done, for example, by a snap connection, but can also be done by a screw connection or other suitable manner.

  Here, the electric drive can be formed as a confined single component, which can be fixed to one of the furniture parts that are pivotally connected in segments. However, the electric drive formed as a confined component has a plurality of component units, which are fixed on a plurality of furniture parts that are pivotally connected in segments as required. It is also possible. Thereby, various hinge types can be taken into account or can be put individually in existing locations inside or outside the furniture part.

  In an embodiment of the present invention, the fixing part is a part of the bolt connecting part. This can be achieved, for example, by the fixing part being formed in the operating device as two perforations, corresponding to a bolt arranged in contact with or in the hinge. The bolt is inserted into the hole so that a connection between the operating device and the hinge can be achieved. Of course, it is also possible to form the fixing part as a bolt and engage with a corresponding perforation arranged on the hinge. Here, this kind of assembly consisting of perforations and bolts is formed to allow the releasable connection between the operating device and the hinge without disassembling the hinge and is arranged on the hinge or operating device be able to. For this purpose, one or more perforations or bolts can be arranged in the outer region of the hinge or operating device.

  According to a preferred embodiment of the invention, the fixing part is formed as a mechanical latch connection. At this time, the fixing portion or a corresponding portion of the hinge that can be connected to the fixing portion may be formed as a latch protrusion. By engaging the latch of this mechanical latch connection portion, the pressure fit connection between the hinge and the operating device is made, so that the operating device can transmit the force or torque provided by the electric motor to the hinge. Thus, the operating device and thus a plurality of furniture parts that are articulated by hinges can be rotated relative to each other.

  Here, the fixing part can have at least one locking member, which is locked to the hinge in the mounting position. At this time, the lock member is formed so as to have spring elasticity, and in the attachment position, the lock member meshes with a corresponding opening formed in the hinge and presses against the spring action of the lock member, so that the lock member is It can provide so that the meshing from an opening part can be removed. With the fixing part formed in this way, the operating device is releasably connected with the hinge as a snap connection, wherein the operating device can be mounted without tools and in addition or instead. Can be removed without tools. In particular, the operating device and the hinge can be releasably connected without disassembling the hinge by the fixing portion formed in this way.

  According to a further embodiment of the present invention, the operating device as a fixed part is at least one first support part formed to be substantially rigid and substantially spring-elastic or spring-biased. At least one second support portion formed in such a manner that the first support portion formed so as to be substantially rigid can be engaged in a recess in the hinge.

  The first support portion formed to be substantially rigid can function as a fixed stopper here. Here, forming with this rigidity should be understood that even if a heavy load is applied on the operation device when the operation device pushes and / or pulls the hinge, no deformation is caused to hinder the function. is there. A second support formed to have spring elasticity or biased by a spring allows the operating device to be connected to a hinge, preferably in the form of a snap-on connection, preferably in the hinge. Can be fitted with a latch, which allows a mechanical latch connection. The connection between the operating device and the hinge can be released by the second support portion being elastically deformed against its spring bias, so that it can be attached without a tool and can be removed without a tool.

  The first support can be formed substantially in the form of a hook or can have at least two hooks. The second support may have a spring tab.

  At this time, the spring bias acting on the second support portion preferably acts in a direction away from the first support portion. It is also possible to provide a further support to limit the position of the operating device, in particular to limit the position of the operating device with respect to sliding or turning of the operating device in the lateral direction.

  The operating device itself may be fixed or integrally formed with the electric drive unit, for example, the housing of the electric drive unit. Here, the operating device can also utilize a further fixing part that can be formed as described above, and by this further fixing part, the operating device can be releasably connected, for example as a snap connection. it can.

  In a particularly preferred embodiment of the present invention, the housing of the electric drive unit has a guide device, and the operating device is slidably guided by this guide device. By guiding the operating device in a slidable manner, the movement path is pre-set for the operating device, and thus also for the hinge or for the furniture part connected to the hinge, so that the fixed path is fixed. The force or torque prepared by the electric motor through the pressure-fitting connection through the parts, a plurality of furniture parts (these are connected in segments so as to be rotatable relative to each other using hinges) Can be used to rotate. Here, slidable means that at least the translational component of the operating device must be present when being guided. The presence of the translation component is useful and space saving because the drive system can be located, for example, near the hinge.

  Here, in a preferred embodiment, the guide device is fixedly arranged relative to one of the furniture parts in the mounted state of the drive system. This enables a particularly stable slidable guide, whereby heavy and large furniture parts can also be rotated by the drive system of the present invention.

  In an embodiment, the guide device has at least one slot arranged in the housing of the electric drive or in the operating device. Here, a guide plug or a guide pin provided in the housing or the other part of both of the operating devices meshes with the long hole to guide the operating device. That is, when a long hole is disposed in the casing of the electric drive unit, a guide plug or guide pin provided in the operating device is engaged with the long hole or vice versa.

  In a preferred embodiment of the invention, the operating device is formed as a lever. Thereby, the force can be transmitted particularly easily. In addition, the lever has a feature that it is a space-saving member for transmitting force. Here, preferably one of the end portions of the lever is pivotally supported in this guide device, preferably pivotably. The end of the lever that faces the pivotally supported end has a fixed portion (the operating device can be releasably connected to the hinge). By supporting the operating device formed as a lever in this way, the kinematic and geometrical requirements necessary for the pivoting movement can be easily met. Here, the lever can further be formed to have two arms, which provides further flexibility. It is also possible to provide the lever so as to be elastic at least in a specific partial region.

  The force or torque provided by the electric motor is transmitted to the hinge directly through the electric motor, and as a result, the furniture part is rotated through the electric motor, the operating device, and the hinge. However, preferably, the electric drive unit is provided with a transmission mechanism. Thereby, a deceleration mechanism and a speed increasing mechanism can also be formed, whereby a particularly heavy furniture portion can be rotated and / or an enlargement of the rotation area can be considered. Furthermore, with this type of transmission mechanism, the rotational movement often generated by the electric motor can be converted into a straight movement of the operating device.

  In general, the drive system of the present invention can use either a rotary motor or a linear motor, which can generate both direct current and alternating current. In order to rotate conventional furniture parts, a slight operating voltage, for example from 5 to 25 volts, is generally sufficient. In this case, the motor output is typically between 2 watts and 30 watts.

  In a further embodiment, the electric motor has a motor shaft, which can cooperate with the operating device via gears and / or friction wheels and / or worm gears supported on the shaft. This is done by arranging these gears in the transmission system between the electric motor and the operating device. These can in this case form part of the transmission.

  Here, preferably, a rack is pivotally supported in the guide device, which rack can be connected on the one hand with the operating device and on the other hand with a gear and / or a friction wheel and / or a worm gear. Yes, and therefore can cooperate or be coupled with an electric motor. With this type of rack, the operating device can be slidably guided. In this case, the rack can particularly easily convert the rotational movement into a translation movement.

  In a preferred embodiment of the invention, the electric motor not only performs a pivoting movement when opening and / or closing the furniture parts that are pivotally connected in segments, but also an opening movement and / or a closing movement. It can also be used as a buffer member or a brake member. It can be provided to apply an inductive load or ohmic resistance to the motor. It is also conceivable to easily short the electric motor.

  Preferably, a connecting portion, preferably an electromagnetic connecting portion, is arranged between the electric motor and the transmission mechanism or between the electric motor and the operating device, and at least a closed state for transmitting the force or torque of the electric motor. The electromagnetic coupling can preferably be switched electrically between an open state that does not transmit the force or torque of the electric motor. However, a mechanically flexible connection, for example a hose connection, is also possible, which transmits the drive noise of the electric motor slightly to the transmission mechanism. In addition to or instead of this type of connection, an embodiment of the present invention is preferably provided with a freewheel that can be turned on and off, so that even if there is no current and the drive system cannot be used, the furniture You can move the part manually.

  In a preferred embodiment, the drive system has an open-loop control device and / or a closed-loop control device in order to perform open-loop control or closed-loop control of the pivoting movement of the furniture part, for example the opening / closing movement of the furniture part. This device comprises a position measuring device and further measuring devices (eg sensors) as required. An example of this kind of open-loop control device and / or closed-loop control device is described in the already mentioned WO 2007/035971 A1 (pages 6 to 10), so here it is more detailed. Is not enough to mention.

  In a preferred embodiment of the present invention, the electric motor can be turned on and off by moving or pushing and / or pulling the furniture part and thus the hinge, for example a stopper part of the hinge, thereby realizing a touch latch function. It becomes possible. In the touch latch function, when the user acts on the furniture portion, the electric motor is released and / or braked to rotate the furniture portion. For this purpose, switchable sensors (eg encoders, potentiometers or other systems for measuring angles or distances, eg optical sensors that react to movement, pushing and / or pulling of furniture parts, etc.) ) Can be used. Similarly, a guided movement sensor can be used, which preferably reacts depending on the direction as the furniture part moves. The measurement signals obtained in this way can be supplied to an open loop control device or a closed loop control device, and in response to these signals, the open loop control device and / or the closed loop control device opens the electric motor. Control or closed loop control. However, it is also possible to provide a manually operable switch that activates or deactivates the motor.

  The present invention further provides a hinge arm for pivotally connecting the drive system implemented as described above and at least two furniture parts using at least two stoppers fixed to each of the furniture parts. And an assembly having a hinge with a hinge cup. These stopper portions can be connected to each other through at least one segment shaft. The operating device of the drive system can be releasably connected to one of the stopper portions.

  The connection between the operating device and the stopper part can be made by a releasable latch connection, preferably by snapping. However, it can also be performed by a screw connection portion or any other appropriate method. At this time, the operating device and the hinge can be connected without a tool. In addition or alternatively, it is also possible to remove the operating device from the hinge, i.e. to release the connection, without tools.

  The stopper part of the hinge is usually a hinge cup and / or a hinge arm. In addition to this, for example, a frame hinge for pivotally connecting furniture portions is also known. Often, the stopper portion can be clipped onto a substrate that can be attached to the furniture portion. Furniture hinges with one or more segment axes exist, and in particular, hinges with a quadrant axis or a seven-segment axis are often used. Often it is a hinge with a two-segment lever, and a so-called wide-angle hinge with a seven-segment axis is often provided, where at least one segment lever is connected via two relatively one segment axes And has a pivotable arm. In order to extend the hinge arm, an intermediate member provided on the hinge arm is further used, which is also pivotally supported by a segment.

  In a preferred embodiment, the drive system can be fixed on the substrate, preferably clipped, like the hinge described above. The drive system board and the hinge are separate and isolated components. Preferably, the drive system can be fixed beside one of the stopper parts, for example beside the hinge arm. However, it is also conceivable for the drive system to be mounted on one of the stoppers, for example clipped.

  In order to particularly stabilize the connection between the operating device and the hinge arm or an intermediate member arranged on the hinge arm, in an embodiment of the invention, the operating device comprises a U-shaped part, and this U The letter-shaped part can be placed over the hinge arm or an intermediate member arranged on the hinge arm.

  The present invention further includes a furniture main body and a furniture door pivotally supported by the furniture main body, wherein the above-described assembly is attached to the furniture main body and the furniture door. About.

  Further details and advantages of the present invention are explained in detail below with reference to the drawings, based on the description of the drawings.

FIG. 1 shows furniture parts 1 and 2 that are pivotally connected with a hinge 3 formed as a wide-angle hinge (hinge, hinge), where the furniture door 2 is the furniture body. 1 is relatively rotated. The hinge 3 is composed of two stopper portions. One of the stopper portions is a double door hinge portion disposed on the furniture door 2 and having a hinge cup 14, and the other is a body hinge portion disposed on the furniture body 1 and having a hinge arm 24. The hinge arm 24 is disposed on the substrate 28, and the substrate 28 is attached on the furniture body 1. Here, for example, the main body hinge part or the hinge arm 24 can be provided so as to be clipped onto the substrate 28. Of course, other fixing methods are also conceivable. The hinge 3 formed as a wide angle hinge in this case achieves an opening angle of more than 90 °. The maximum opening angle of this type of wide-angle hinge is often 170 ° to 180 °. In order to lengthen the hinge arm 24, an intermediate member 16 is disposed between the two original stopper portions, and this intermediate member 16 is movable via the segment levers 17a and 17b and the further segment levers 26a and 26b. Are arranged as follows. At this time, a segment lever 17a is connected to the intermediate member 16 by a segment, and the segment lever 17a is connected to the hinge cup 14 by a segment via a segment lever 17b. Further pivotable segment levers 26 a, 26 b serve to forcibly guide the intermediate member 16 relative to the hinge arm 24. In this case, the hinge 3 formed as a wide-angle hinge has seven rotation axes S ₁ , S ₂ , S ₃ , S ₄ , S ₅ , S ₆ , S ₇ , and of these rotation axes, the rotation axis S _6. S ₇ is inside the hinge cup 14.

  The drive system 4 of the present invention is disposed on a substrate 10 that is isolated from the hinge 3 and attached to the furniture body 1 in the same manner as the substrate 28. Here, the drive system 4 can also be releasably latched onto the substrate 10, for example by clipping. A cable 13 disposed in or on the furniture body 1 is guided into the substrate 10 and functions to supply power to the electric drive unit 18. In this case, for example, when the drive system 4 is latched, the cable 13 can be pierced so that an electrical contact can be made. The electric drive unit is composed of components that are isolated from the hinge 3. The drive system 4 itself is arranged behind the main hinge part of the hinge 3 and is fixed by means of a fixing member 36 (which is preferably connected with a corresponding member 43 arranged on the substrate 10 by snapping). It is fixed on the substrate 10.

  In this case, the operating device 8 is formed as a two-arm lever and functions to transmit force or torque provided from the electric motor 18. The operating device 8 here comprises lever arms 11, 12 which can be rotated in the reverse direction via the segment shaft 15. At least one long hole 6 is disposed in the housing 5 of the drive device, and this long hole functions to guide the operating device 8 so as to be slidable. The guide pin 7 is connected to the operating device 8 and cooperates with the drive system of the electric motor 18. In order to open and close the hinge 3, the guide pin 7 slides in the long hole 6 in the reciprocating direction. At this time, the operating device 8 is releasably connected to the main body hinge portion, to be precise, the intermediate member 16, by the fixing portion 9 disposed on the lever arm 12. Here, the lever arm 12 has a U-shaped portion, and this U-shaped portion covers the intermediate member 16. Of course, connection with the hinge arm 24 itself is also conceivable.

  In FIG. 1, the furniture door 2 is already wide open. That is, the furniture door 2 rotates relatively widely with respect to the furniture body 1. Here, when the electric motor 18 is started to close the furniture door 2, the guide pin 7 is thereby displaced in the guide device, that is, in the long hole 6, in the backward direction, that is, in the direction away from the hinge arm 24. Thereby, force is transmitted to the hinge 3 via the operating device 8, and the furniture door 2 rotates to a closed state.

  FIG. 2 shows the assembly shown in FIG. 1 with the contents opened, and this assembly comprises a drive system 4 and a hinge 3 formed as a wide-angle hinge. The hinge 3 connects the furniture portion 1 and the furniture portion 2 with segments. The fixing member 36 of the drive system 4 together with the corresponding member 43 forms a mechanical latch connection, which functions to fix the drive system 4 on the substrate 10.

FIG. 2 shows substantial electrical components of the drive system of the electric drive unit. The electric motor 18 drives a motor shaft 28, and the motor shaft 28 is connected to gears 20, 22, and 29 via a worm 21. These gears 20, 22, 29 and the worm 21 are a part of the transmission mechanism. It is also possible to form one or more of the gears 20, 22, 29 as a friction wheel. Here, it is also possible to arrange another coupling mechanism between the motor shaft 27 and the transmission mechanism or between the transmission mechanism and the operating device 8. In addition or in the alternative, it is also possible to provide a freewheel, so that the furniture door 2 can also be moved manually, in particular when the drive system is deactivated. The gears 20, 22, and 29 drive the rack 19 that performs translational motion. Thereby, the rotary motion generated by the electric motor 18 is converted into a translational motion. The rack 19 is connected to the guide pins 7 and thus to the operating device 8, and the operating device 8 is forcibly guided by the guide device, i.e. the slot 6, so that the operating device 8 also translates, Thereby, relative rotation with respect to each other of the furniture part 1 and the furniture part 2 is performed reliably. In addition to this, the operating device 8 is pivotally supported in the slot 6 so that the movement of the operating device 8 also has a rotational component. FIG. 2 also shows the segment shafts S ₃ , S ₄ , S ₅ , S ₆ , S ₇ , and the fixing portion 9 disposed below the lever arm 12.

  FIG. 3 is a plan view of the assembly shown in the above figure, which consists of a hinge 3 and a retrofitted drive system 4, which consists of lever arms 11 and 12. They are releasably connected to each other via the device 8. In the state shown in FIG. 3, the furniture door 2 is partially opened and the opening angle is in the first third state between a closed state and a fully open state. The opening angle in the present embodiment is about 170 ° in the fully opened state.

  FIG. 4 is a cross-sectional view taken along the line AA in FIG. 3, which shows the substantial electrical components of the electrical drive of drive system 4. Here, the substrate 10 (on which the electric drive unit formed as a confined component is fixed) is mounted on the furniture body 1 by the fixing device 23. Here, the electric drive can be clipped onto the substrate 10 using a mechanical latch connection. For this purpose, the fixing member 36 is connected to the corresponding member 43 formed on the substrate 10 side so as to have spring elasticity or biased by the spring. Of course, other ways are possible, for example screw connections. In FIG. 4, the gear 29, together with the further gears 20, 22, cooperates with the motor shaft 27 via the hose connection 39 and functions to transmit force to the operating device 8. The furniture door 2 is in a partially open state, so that the guide pin is not in contact with one end of the long hole 6. In this case, the opening angle is in the first approximately one third between the closed state and the fully open state, but the guide pin 7 is located at approximately half of the longitudinal extent of the slot 6. To do. This is because of the transmission mechanism formed by the gears 20, 22, and 29. In FIG. 4, the other rotation axes S1 and S2 of the wide-angle hinge that cannot be seen in FIG. 2 can also be seen. Between the rotary shaft S1 and the rotary shaft S2, a further rotatable segment lever 26a is arranged, which, together with the further rotatable segment lever 26b, makes the intermediate member 16 relative to the hinge arm 24. Forced to guide. The hinge arm 24 itself is fixed on the substrate 28. The other unreferenced components of the hinge 3 and the drive system 4 are known per se from the prior art and therefore need not be described in further detail here.

  In the plan view of FIG. 5 and the cross-sectional view of FIG. 6 (this is a cross-sectional view taken along the line B-B in FIG. 5), the drive system 4, the hinge 3, and the hinge 3 are used. As can be seen, an assembly comprising furniture parts 1 and 2 connected in segments is seen, but the rotated furniture door 2 is in a further open state, that is, the opening angle of the hinge 3 is shown in FIG. Bigger than that. This opening angle is about 140 ° in this example. The maximum opening angle of the hinge 3 formed as a wide-angle hinge is about 170 °. Therefore, the guide pin 7 connected to both the operating device 8 and the drive system of the electric drive unit is in the vicinity of the end of the long hole 6 on the hinge 3 side. Therefore, the operating device 8 can move only a small distance in the direction of the hinge 3. This distance corresponds to the remaining opening angle until the hinge 3 is fully opened. Here, there is provided a motion sensor or measuring device for measuring the relative position between the furniture part 1 and the furniture part 2 and supplying it to an open loop control device (not shown) or a closed loop control device. It is also possible for a controller or a closed loop controller to stop the electric motor 18 from operating at the correct time. However, it is also possible for the sensor to measure the position of the guide pin 7 in the slot 6 and thereby stop the operation of the electric motor 18 at the correct time. Of course, other possibilities known from the prior art for actuating or deactivating the electric motor 18 can be considered.

  The plan view of FIG. 7 and the cross-sectional view of FIG. 8 (this view is a cross-sectional view taken along the line C-C in FIG. 6) are rotated by the drive system 4 by the hinge 3. The place where the furniture door 2 is in a closed state is shown. For this purpose, the guide pin 7 connected to both the operating device 8 and the drive system of the electric drive unit is in the vicinity of the end of the long hole 6 away from the hinge arm 24. Again, various possibilities exist as to how the electric motor 18 is activated to open the furniture door 2 and how the electric motor 18 activated for the closing process is deactivated. is there.

  FIG. 9 is a perspective view of two corresponding furniture parts 1 and 2. These two furniture parts are parts to be connected by segments so as to be rotatable relative to each other. FIG. 9 is a diagram directly showing the advantages of the drive system 4 of the present invention. A substrate 28 for the body hinge part, in particular for the hinge arm 24, is mounted on the furniture body 1 in the same way as the substrate 10 of the drive system 4. The drive system 4 itself is also fixed on the substrate 10 using, for example, a latched snap connection. The hinge 3 formed as a wide-angle hinge is mounted together with the furniture door 2 at the hinge portion of the double door, i.e., in particular at the hinge cup 14. Starting from the situation illustrated here, the hinge arm 24 can be simply fixed on the substrate 28 as is already known in the prior art. In this regard, it is likewise possible to provide latching means, so that this fixing is achieved, for example, such that the hinge arm 24 is clipped onto the substrate 28. The side parts 25 ', 25 "of the housing 5 of the electric drive function mainly for visual purposes.

  When the hinge 3 is connected to the substrate 28, the operating device 8 can be releasably connected to the hinge 3. For this purpose, recesses 30 ′ and 30 ″ are arranged on the intermediate member 16 of the hinge 3, and the fixing part 9 arranged on the lower surface of the operating device 8 can be engaged with these recesses. Here, only these recesses 30 ′ and 30 ″ are different from the conventional wide-angle hinge for realizing the retrofit of the drive system 4 of the present invention. Here, the operating device 8 formed as a lever presses on the hinge 3 connected to the substrate 28, whereby the fixing portion 9 is engaged with the recesses 30 ′ and 30 ″ and is fitted in the latch at that position. By specially forming the fixing part in this way, this connecting part can also be removed.
