Description

The present invention relates to a furniture hinge according to the preamble of claim 1 (see, eg EP-A-1128012 ).

In furniture hinges mechanical dampers and closing devices are known. These influence the movement of furniture furniture connected via a furniture hinge but only in a small angular range of the closing or opening movement. The remaining pivoting of the furniture parts is still done manually in the prior art.

The object of the invention is to find a more comfortable solution here.

This is inventively achieved by the furniture hinge has at least one motor, preferably electric motor for pivoting the stop parts.

Furniture hinges are usually hinges with a hinge pot and / or a hinge arm as a stop. In addition, however, so-called frame hinges are also known. Often the stop members are aufklippsbar on a fastened to a furniture part base plate. There are furniture hinges with one or more hinge axes. Furniture hinges are frequently used in which the stop pieces can be connected to one another via four or seven joint axes. These are usually hinges with two articulated levers, wherein it is often provided in so-called wide-angle hinges with seven articulated axles that at least one articulated lever has two legs which are pivotable relative to one another via a hinge axis. A basic feature of all furniture hinges is their dual function. On the one hand, they carry the pivoting furniture part, on the other hand, they allow and guide the pivoting movements. According to the invention, a third function, namely the motor drive of the gift, is now additionally provided in the case of the furniture hinges.

The motors preferably used for pivoting the stop parts have a motor housing and at least one motor shaft, the latter being rotatable or longitudinally displaceable relative to the motor housing. In furniture hinges, as the embodiments will show in more detail, both Rotary motors and linear motors are used. Both can be designed both as a DC and as an AC motor. For furniture hinges, it is often sufficient to provide motors with comparatively low operating voltages, preferably direct voltages, between 5 volts and 25 volts, preferably 24 volts. The electric power to be provided by the motor is usually between 2 and 30 watts, preferably between 4 and 20 watts.

The motor can be used not only for pivoting the stop members when opening or closing but also for damping or braking the opening and / or closing movement. For this purpose, the motor can be loaded both inductively and with an ohmic resistance. The maximum damping effect is achieved by simply shorting the motor.

The motor can drive with its output or its motor axis directly a hinge lever or a hinge axis of the hinge. But it can also be provided gear. Moreover, as described in detail below, it is favorable if a, preferably electromagnetic, clutch is arranged in the output of the engine, which clutch is arranged at least between a closed state in which it transmits a force or a torque of the motor and an open one State in which it transmits no force or no torque of the motor, preferably electrically, is switchable. Instead of or in addition to the coupling and furniture hinges and preferably motors with a, preferably on and off, freewheel can be used, for example, to move the hinge in case of power failure by hand.

First, based on the Fig. 1 to 15 various examples show how motors can be arranged according to the invention on different hinge types.

The Fig. 1 to 5 show an embodiment in which an electric motor 6 is arranged laterally on the hinge arm 3. The hinge arm 3 itself is, as is known, aufklippsbar on an anchored in the furniture part 1 base plate 7. But it is also possible any other known in the prior art mounting variant. The motor 6 is fixed here with its motor housing 11 on the hinge arm 3. The housing 11 could also be arranged on each other stop part. In the output of the motor, a preferably electrically switchable coupling 13 is provided between the gear 17 and the motor on the motor shaft 12. This is switchable at least between two states. In the so-called closed state, a force or torque of the motor 6 is transmitted, while in the so-called open state, no force or no torque is transmitted from the engine. In addition, it is advantageously provided that the strength of the coupling force is variable. In addition, the output in the form of the motor shaft 12 can also cooperate with a aufwendinger designed gear if necessary. Conveniently, electromagnetic clutches 13 are used, since they can be built very small and easily controlled.

The force or torque transmission takes place when the clutch 13 is closed by the gear 17 on a second gear 19 which is rigidly connected to the inner lever 8 'via the hinge axis 5'. In this way, caused by a motor 6 rotary motion in a pivoting of the articulated lever 8 'are transmitted, whereby the two stop parts - here the hinge arm 3 and the hinge cup 4 - and thus the two furniture parts 1 and 2 are pivoted against each other. The transmission of the rotational movement over the gears formed from the gears 17 and 19 has been selected in this embodiment, for reasons of space so that when opening and closing no collision between the motor 6 and furniture part 2 is formed. However, a transmission can also be used to lower or translate the rotational movement of the engine, if correspondingly higher or lower torques are required. With appropriate Space could be the engine but also directly on the axis 5 'of the inner joint lever 8' or the outer joint lever 8 flanged. It is also conceivable to use other axes of rotation 5 for transmitting the forces.

In order to determine the actual position and / or the actual speed, an encoder 14 which has an encoder disk 15 and a light sensor 16 is provided in this exemplary embodiment. Alternatively, as a motion or position sensor but also a potentiometer or the like could be used. It is advantageous to use absolutely measuring angle or length measuring systems, which can determine the absolute position of the toggle lever 8 'or axes 5' and thus the stop parts to each other even after a power cut or a power failure. As explained below with reference to various control schemes, the described sensors can be used both for position and velocity determination and as a switch for triggering or stopping a movement. In embodiments such as the Fig. 1 to 5 the motor shaft 12 is arranged coaxially with or parallel to the or one of the joint axes 5, 5 '.

The Fig. 6 to 8 show an embodiment according to the invention, in which the motor shaft 12 is arranged substantially perpendicular to the hinge axes 5, 5 '. Here it makes sense to provide between the motor shaft 12 and the driven joint axes 5 'or articulated levers 8' a worm wheel 18 comprehensive worm gear. The sectional view according to Fig. 7 and 8th show as the sectional view according to 4 and 5 , via which components the transmission of the rotational movement from the motor shaft 12 to the articulated lever 8 'takes place. Again, the gear 19 is rigidly connected to the hinge axis 5 'and the hinge lever 8'. The mounting bracket 20 holds the motor housing 11 in the optimal position for this arrangement, so that engagement of the worm 18 is ensured in the gear 19. In the embodiment according to the Fig. 6 to 8 the encoder and the freewheel or the clutch are integrated into the motor housing 11. So they are not visible from the outside. Of course, these types of motors can basically be used in all embodiments. Alternatively, it is also possible to use corresponding stepper motors.

The Fig. 9 to 13 show in embodiments how so-called wide-angle hinges can be equipped by means of motors 6 for pivoting the furniture parts 1 and 2. The wide-angle hinges have - as is known - seven joint axes 5, 5 ', wherein the outer articulated lever in the form of two relatively pivotable legs 9 and 9 'is formed. The motor housing 11 is in the embodiment according to the Fig. 9 to 11 arranged on a pivotable relative to the hinge arm 3 intermediate part 10. The motor shaft 12 simultaneously forms one of the joint axes 5 '. On her sits a gear 17, which drives a second, rigidly on the driven leg 9 ', gear 21 drives. The arrangement of the gears 17 and 21 is particularly good in the sectional view according to Fig. 11 to see. This also shows the lever 23, which together with the leg 9 'allows the pivoting of the intermediate piece 10 relative to the hinge arm 3.

In the embodiment according to the Fig. 12 and 13 a linear motor is used instead of a rotary motor. Also in these favorably both the encoder for position and speed determination and the clutch or the freewheel is integrated. The movement of the hinge is effected by extending or retracting the motor shaft 12 into the motor housing 11. In the illustrated embodiment, the motor housing 11 is pivotally mounted on the intermediate part 10 and the motor shaft 12 pivotally mounted on the hinge axis 5 '.

The embodiments according to the FIGS. 14 and 15 shows an example of how a so-called frame hinge with a motor 6 - here a linear motor - can be equipped. On attachable to the furniture frame 1 stop member 24, a support lever 25 is arranged for this purpose, on which the motor housing 11 is pivotally supported. The retractable into the motor housing motor shaft 12 is pivotally mounted in the hinge cup 4. As with all embodiments, it makes sense here, not self-locking form the transmission and motor so that - for example, in the case of a power failure - an opening and closing movement by hand is possible.

The control or regulation of the motor 6 for pivoting the stop members will now be described with reference to two schematic circuit diagrams according to FIGS. 16 and 17 explained. It should be noted that, among other things, all previously shown variants, such as a motor 6 may be arranged on the furniture hinge, are appropriately regulated or controlled.

Fig. 16 shows a very simple embodiment. Here is the engine over in the Fig. 1 to 15 not explicitly shown power lines 38 connected to a power source 37 and a switch 36. The motor 6 pivots about the motor shaft 12, the stop parts of the Furniture hinge 35. In a very simple embodiment of - for example, manually operable switch 36 has three switch positions. In a first, the motor 6 is driven so that it moves the furniture hinge 35 in the open position. In a second switching position of the switch 36, the furniture hinge 35 is pivoted in the direction of the closed position. In the third position, the motor 6 is de-energized, so he then performs no movement. In this switching state, a clutch present in the motor 6 is favorably opened or a freewheel activated, so that the furniture hinge can be pivoted by hand for emergency. In addition to a manually operable switch 36 switchable sensors can also be used by a movement or pressure and / or Zugbeaufschlagung the stop or furniture parts. These may be, for example, the previously mentioned encoders 14 or potentiometers or other angle or distance measuring systems, such as optical sensors or the like. However, it can also be provided that the motor has an inductive motion sensor, by means of which it can be switched on and off during a movement of the stop parts, preferably in a direction-dependent manner. Is in the de-energized state, the clutch or the freewheel open, it can be conveniently provided mechanical holding devices that hold the furniture hinge 35 at rest in the respective position.

In Fig. 17 a preferred arrangement is shown. Here, a control device 29 takes over the regulation of the opening and closing movements of the furniture hinge 35. The control device 29 may additionally be connected to a switch 36 mentioned above and have further communication interfaces 30 for data transmission or for transferring control software. The control device 29 is conveniently designed as a microcontroller. Preferably via the power line 38, it controls the motor 6. Via a first data line 39, it receives information about the actual position and / or actual speed of the abutment parts of the furniture hinge 35 from corresponding sensors in the motor 6 or in the furniture hinge 35 and a signal about the switch state of the coupling 13. Via a second data line 40 receives them from also in the engine 6 and / or in the furniture hinge 35 can be arranged sensors switching commands for pivoting the stop parts or to stop the movement.

It is expediently also to use the sensors for determining the actual position and actual speed as sensors for the transmission of switching commands. Thus, for example, the slight tapping or pulling on the furniture part 2 can be transmitted via the corresponding stop member to an encoder or a potentiometer.

This sensor then passes the information on the first data line 39 to the control device 29, which interprets this signal when exceeding an adjustable threshold as a command to pivot the furniture hinge and controls the motor 6 accordingly. The motor 6 can be controlled so that it supports the movement started on the furniture part by hand or takes over entirely. Thus, it may be provided, for example, in a particular embodiment of the switch 36 that they are arranged on the door handle and respond to appropriate pressure or pulling movement on the door handle. The control device 29 can pivot in this way, the furniture hinge 35 via predeterminable angle ranges in the opening or closing direction, approach the full closing or opening positions but also dampen too vehement transferred by hand to the furniture part movements. It can also be provided that after a pulse on the furniture part, the furniture hinge 35 is brought into the complete closed or open position. For accelerating and braking the abutment parts or the motor shaft 12, default values or functions can be stored in the control device 29, in which a certain reaction to a detected introduction of force is stored in the furniture part or the abutment part. It can also be provided that the control device brings the stop members in the closed position, if after a predetermined time interval no new drive signal for opening and / or closing has been detected. Of course, the control device 29 also takes over the activation of the clutch 13 via the third data line 41 and switches it at least between the closed and the opened state. The same applies to the optionally provided freewheel. The control device 29 may be arranged separately but also on the furniture hinge or integrated into this.

Fig. 18 shows a control scheme for the operation of a motor hinge according to the invention by means of a control. The regulation and monitoring of the movement process during opening, closing and braking or stopping takes over the control device 29. It controls a power actuator in the form of an amplifier stage 32 at. This electronic power amplifier amplifies the signals of the controller 32, then to control the motor 6 accordingly. The task of the motor 6 is to convert both - preferably electrical - energy into mechanical energy in order to pivot the furniture parts against each other, as well as during the braking process to convert mechanical energy into, preferably electrical, energy. The coupling of the motor 6 to the moving furniture hinge 35 can be done as already stated via a coupling system 13 and optionally in addition to a gear for under or translation. The Control of the clutch 13 is also done by a signal line from the controller 29. When giving away the furniture parts 35, the sensor system 34 converts the physical variables necessary for process control, such as actual position, actual speed (possibly rotational speed), acceleration (possibly torque) into, preferably electrical, signals and supplies a standardized (bus-capable) output signal the controller 29. For this signal or information transfer between the sensor system 34 and controller 29, depending on the complexity of the data exchange either an analog interface (for example voltage interface with 0 to 10 volts) or a bus-capable interface is used. An additional operating element 28 can be connected to the control device 29 via a corresponding analogue or bus-capable interface. The control element 28 may be designed in the form of switches 36, special actuators, for example, to support the manual operation, or optionally also as an emergency stop button. In addition, a display or visualization element 27 can optionally also be connected to the control device 29. Again, one will provide either an analog or a bus capable interface depending on the favorably type of display element. In particular, for dubbing of control and regulation software 26, it is generally favorable if the control device 29 still has a communication interface 30 for parameterization and / or programming. This advantageously allows a connection to a PC or the like and can also be used to exchange information with a possible higher-level control or regulating device in which, for example, a plurality of drives are networked with each other. As a rule, bus-capable interfaces are also used here. Depending on the design of the control device 29, various components of the software 26 are provided. One of these is used for process control and, if necessary, autoparameterization of the control process. In addition, software components for controlling the interfaces can also be provided. Also for diagnosis and parameterization of the drive various software components can be provided. Thus, the entire movement process during pivoting of the furniture parts can be visualized. In addition, software for manual parameterization of the drive system and for overall operation and diagnosis of the drive system can also be provided. The power supply 31 for the energy input into the overall system is conveniently a 24 volt DC power line. In the design of the power supply is generally assumed that a maximum mechanical power of about 5 watts is provided, resulting in an efficiency of about 25%, an electrical power of the drive of about 20 watts.

Fig. 19 shows a flow diagram for the motorized pivoting of two connected via at least one inventive furniture hinge furniture parts, such as a furniture door and a furniture body. Against a time axis t is the opening angle a - measured between the furniture door and furniture body -, the coupling current I _K and the motor current I _M applied. α = 0 corresponds to the position of the closed door. α _max means the maximum opening of the door. At I _Kmax , the clutch is in the closed state. Here, the force or torque of the motor 6 is transmitted. When I _K = 0, the clutch is open. A motor current I _M = 0 means that the motor is not turning. With the I _{M +} , the motor turns in the direction of the open position, with I _M- in the direction of the closed position. In the following description of the sequence of movements, it is assumed that the command to open the door is given to t ₀ via a switch 36. At time t ₁ , the clutch is closed. At time t ₂ , the engine starts and the door starts to open. At time t ₃ , the clutch is opened and the door is braked by a mechanical braking system, such as a damper, prior to reaching the open position. At time t ₄ , it reaches its maximum opening angle α _max . The engine is on display. Of course, instead of a mechanical brake system, it may also be provided that the engine is exposed and loaded or short-circuited before opening the clutch, ie before t ₃ . He then takes over the damping function as long as the clutch is closed.

As long as the door should remain in the open position α _max , the motor and clutch are de-energized. The clutch is open. At time t ₅ , the switch 36 receives the command to close the door. The clutch is closed. At time t ₆ , the engine is turned on. He now closes the door, which can be recognized by the course of α. Before reaching the full closed position (α = 0), the clutch opens at time t ₇ . The engine is switched off at time t ₈ . On the remaining closing path Δα, the door is closed by a mechanical locking system known from the prior art. Alternatively, it is of course also possible to dispense with the mechanical locking system and keep the engine with the clutch engaged longer in operation until the door is closed. Again, the deceleration can be done by means of a motor or by means of a mechanical damper.

In Fig. 20 the sequence of movements is shown in an alternative form of control. Here, the triggering of the closing and opening movement of the door is not carried out by actuation a switch 36 or the like but by a slight pivoting α _{s of} the furniture door. This is detected by a corresponding sensor, such as an encoder or potentiometer, and forwarded to the control device 29. This interprets the pivoting when exceeding a presettable threshold as a switching command and closes at time t _1, the clutch. At time t ₂ , the engine is turned on to open the door. Upon reaching a certain opening angle α at the time t _a, the sensor system notices that the door is manually accelerated by a user in the opening direction. The controller then opens at time t _a the clutch and turns off at t _b the engine. At time t _c , the sensor notices that the door is no longer moved by hand. The control device 29 switches on the clutch at time t _c and the motor at time t _d again to fully open the door. The remaining process until reaching α _max corresponds to that of the example according to FIG Fig. 19 , Also, the closing operation begins from the time t ₅ , as stated above. The triggering at the time t ₅ can be done both by a slight pivoting of the door, as at α _s or via a switch 36. Even when closing the door now the intervention of a person is shown in the closing process. Thus, at time t _e, the sensor registers that the door is manually accelerated. The clutch is opened. The engine is switched off at time t _f . At time t _g , the sensor registers the end of the operation of the door by hand. The clutch is switched on again. The motor follows at time t _h and closes the door until the mechanical closing system takes over the final closing on the residual travel Δα.

Depending on the type of furniture parts to be pivoted, it may be sufficient to equip a furniture door with only one motor-driven hinge and additionally several standard hinges.
