Description

The present invention relates to an arrangement with at least one movable Furniture part, in particular with a drawer, or the like, with at least one Drive unit and with at least one control device for controlling the at least a drive unit.

Such arrangements are already known in principle. US 5,158,347 describes For example, an office furniture in which the drawers after entering an identification code be moved by a motor over a first area of the entire opening path. EP 0 957 225 describes an opening device for a closure element, for example a drawer that has a condenser that contacts itself through the User discharges electrically, is triggered. Again, only a partial move out the drawer from the furniture body. The German patent DE 10 17 351 describes a device for removing or inserting drawers in pieces of furniture, which is arranged by body side pushbuttons can be triggered. It is with the help of Push buttons every possible positioning of the drawer along the entire opening path possible. The problem in this context is that such opening aids Always be triggered on specially designed actuators, which is of many Users is perceived as unpleasant. Especially for people who like technology Generally skeptical, it would be advantageous to powered movable Furniture parts in the old traditional way by pulling or pushing the drawer to be able to serve.

The object of the present invention is to provide a generic arrangement, an intuitive operation of a driven by a drive unit movable Furniture part allows.

This is inventively achieved in that the arrangement at least one, preferably has analog, acceleration measuring device, wherein the at least one Acceleration measuring device for a through from the outside to the at least one movable Furniture part applied forces caused accelerations characteristic acceleration signal generated, which is the at least one control device supplied.

Technically advantageous is that in the inventive arrangement no Actuators for triggering the drive unit for the movable furniture parts more are provided. Economically advantageous is that a greater acceptance of the inventive arrangement is expected on the market.

It does not matter if the acceleration is measured directly or from another measured quantities is calculated. In this sense, also constitutes an institution Positioning of the movable furniture part together with a clock one In this case, from the in a certain Time span traveled the speed and change of the distance Speed the acceleration can be determined.

However, according to the invention, it is sufficient to recognize the fact that a Acceleration of the movable furniture part is done, regardless of the amount or the Direction of acceleration.

Conveniently, in one embodiment of the invention, it is provided that the at least a drive unit comprises an electric motor. Such electric motors are in Miniature construction commercially available and guarantee a low power consumption trouble-free operation.

A particularly advantageous embodiment of the invention results from the fact that the Acceleration signal information about the amount and / or direction, preferably via the direction component parallel to the extension direction of the movable Furniture part caused by externally applied to the movable furniture part forces Acceleration includes. Thus, the acceleration measuring device of the Control device provide information on which direction the Operation of the drawer should take place. Receives the control device, for example, from the Acceleration measuring device, the signal of a present Zugbeschleunigung can the drive unit immediately a control command to move the movable furniture part send in the direction of measured train acceleration. It plays in and of itself No matter in which opening state the drawer at the time of external Actuation is located. Conveniently, it is provided that in a certain range in front of the open as well as the closed end position of the movable furniture part no driven movement of the furniture part is done more to damage the furniture part or to prevent the inventive arrangement. For this it is advantageous that the Arrangement comprises at least one position measuring device, which is one for the Opening state of the movable furniture part characteristic and the control device generates deliverable position signal. So the controller can recognize at any time whether the movable furniture part is near one of the end positions.

Advantageously, the acceleration signal included by the Acceleration measuring device goes to the control device, also information about the amount of user-applied acceleration of the movable furniture part. Out For example, a large amount of acceleration can be inferred that a rapid opening or closing is desired, whereby the control unit the Drive unit of the situation can operate accordingly.

An advantageous embodiment of the invention results from the fact that the Drive unit approximately the movable furniture part over a predetermined period of time evenly accelerated. Thereby, that the acceleration of the movable furniture part takes place only for a predetermined period of time, the illusion of one does not for the user maintained driven furniture part. After the expiration of the period of time becomes the movable Furniture part braked by the systemic friction, just as if no Drive unit would be available. However, it could also be provided that after the Acceleration period a lower acceleration to compensate for by the Friction caused braking is maintained. This will give the impression of a maintained non-powered furniture part, for example, particularly low friction is stored. Alternatively or additionally, it can also be provided that the drive unit the movable furniture part only via a predetermined or predetermined partial path, the Length is less than the length of the total path between the closed and the opened end position of the movable furniture part, accelerated. Because of that Drive unit is not active over the entire opening path is the desired Retain invisibility of the technique.

It can also be provided that the movement of the movable furniture part through the Drive unit is independent of the amount of tensile or compressive acceleration. Thereby Only the user decides by the amount of his effort, how fast the Movement of the movable furniture part should be carried out, being always by the drive unit the same supporting acceleration occurs.

A particularly advantageous embodiment of the invention results from the fact that the Control device has an actual value calculation device, which from the of Position measuring device generated position signal, the current actual position and / or the current actual speed of the movable furniture part calculated. By the It is aware of the current position and speed of the movable furniture part possible, on defined sections, for example in the vicinity of the end positions of movable furniture part to make by the drive unit acceleration such that the movable furniture part comes to a standstill in the respective end position.

In a further advantageous embodiment of the invention it is provided that the Arrangement comprises at least one initialization device, each one for certain predetermined positions of the movable furniture part characteristic, generated at least the position measuring device, signal generated. Is the inventive arrangement not with expensive permanent electronic storage elements equipped, for example, after the separation of the invention Arrangement of the voltage source, the position of the movable furniture part with respect to the arrangement according to the invention can be determined. As the inventive arrangement Moreover, it can be available in various dimensions on the market, it is at least at the first commissioning necessary, the length of the total route between the closed and the open end position of the movable furniture part as well the positions of the movable furniture part in the closed and the open end position determine. This can be done, for example, that the user the Initialization device via an easily accessible from outside the arrangement Actuating element, such as a button, triggers. In such a Initialization process can be provided, for example, that the user moved movable furniture part in the closed end position, there the actuator actuated and then moves the movable furniture part in the open end position and in turn actuates the actuator. As a result, the control device are the required information about the total length of movement of the movable furniture part as well as the position of the movable furniture part in the special layers available.

Alternatively or in addition to an initialization by collision detection would be possible. The movable furniture would slowly move towards one of the two Driving end positions and when they reach the detected collision automatically Trigger the initialization device. For example, the movable furniture part could through the drive unit is first moved in the direction of the closed end position and in collision the front panel with the front of the arrangement automatically zero position through the Initialization device are detected. After that, the movable furniture part could moved by the drive unit in the direction of the open end position and in collision automatically this position be determined by the initialization device. The collision itself could e.g. by a sudden increase in the drive unit supplied current, wherein the increase on the movable between Furniture part and arrangement occurring forces is due to the drive unit to tried to overcome. When exceeding a certain amperage it would be natural to shut down the drive unit to prevent damage. It would be also possible to trigger the initialization device when the amount of Speed of the movable furniture part smaller over a given period of time is equal to a predetermined limit, preferably zero.

In a touch-latch embodiment, the one specified by the initialization device would be closed end position of course not the position of the movable furniture part in collision, but a location further out by a predetermined distance. This would be the required for the touch-latch release gap between the front of the arrangement and the front panel of the movable furniture part in the closed end position ensured become.

In a further advantageous embodiment of the invention it is provided that the Initialization device via a disposed within the array, the movable Furniture part operable actuator is triggered. This will give the user the Actuation of a special actuator saves. Such within the Arrangement arranged actuator can, for example, as a limit switch for Determining the closed end position of the movable furniture part to be formed. By way of example, it can be provided that this limit switch is designed as a pressure switch is. By inserting the movable furniture part either via the drive unit or by the user, the limit switch on the last millimeters of the Insertion path operated by the movable furniture part. This will make the closed End position of the movable furniture part set in the inventive arrangement. It can also be provided that the limit switch or the actuating element in generally designed as an inductive or capacitive sensor, so that the registration the respective end positions of the movable furniture part can be done without contact. Also Other types of sensors known to those skilled in the art may be provided.

It is also conceivable that the initialization device by the production of a conductive Connection of the arrangement with a voltage source via a trigger element triggered is. This will automatically initialize the first time Commissioning or when restoring the power supply to one Power failure.

Of course, can also be provided, two or more versions of above-mentioned operations of the initialization device in an inventive Combine arrangement. The triggering of the initialization device can Of course, also done by hand extract. In this case, the movable furniture part is manually by a user, for example, from the closed end position in the fully open End position moves.

In a further advantageous embodiment of the invention it is provided that the movable Furniture part movably mounted on laterally arranged within the arrangement of frames is. Such frames, which are state of the art in their own right, allow the low friction and safe storage of the movable furniture part in the invention Arrangement.

In a further advantageous embodiment of the invention it is provided that the Drive unit is attached to a frame. This can, for example, for each movable furniture part is provided its own drive unit. It can also be possible from the outset frames on which drive units are mounted in to install an arrangement according to the invention.

In a further advantageous embodiment of the invention it is provided that the Drive unit on the rear wall of the movable furniture part opposite inner surface the arrangement, preferably at approximately the same distance from the two side walls the arrangement is attached.

This is the result Acceleration of the movable furniture part by the drive unit regardless of the current position of the movable furniture part with respect to the inventive Arrangement possible. For example, suggests that the drive unit via at least one rope or a belt, preferably a toothed belt, or one in one Rack-engaging gear in constant communication with the movable furniture part stands. The use of a toothed belt guarantees the slip-free connection between the movable furniture part and the drive unit. The exercise of power can For example, take place in that the belt over at least two rollers running on the a side frame are arranged. Of course you can also use both side frames be carried out at least two roles, each having a belt for power transmission to be led. Of course, the use of a rope without slippage would be possible if are fixed on the driven roller both ends of the rope and thus at the same time the one Rope end unwound and the other end of the rope is wound up.

From a certain width of the movable furniture part, it is advantageous that at least two arranged on different frames rollers over a connecting shaft with each other in - Preferably rigid - connection and are so moved by the drive unit.

A further advantageous embodiment of the invention results from the fact that at least one roller is drivable on at least one frame by the drive unit. This allows a lower-loss power transmission than in the interposition of Transmission devices between the drive unit and the movable furniture part would be achievable.

To a cheaper translation of the movement of the drive unit to the movable To achieve furniture part, it can be provided that the at least one roller on at least a frame via a transmission by the drive unit is driven. At a wide movable furniture part, it offers itself again, at both ends of the connecting shaft Provide gear. For very wide movable furniture parts can also be provided To arrange on both sides of the movable furniture part drive units, either have their own control devices and a synchronization device or be driven by a common control device.

In a further advantageous embodiment of the invention can be provided that the arrangement comprises a resolver for measuring the position and / or the speed and / or the acceleration of the movable furniture part comprises, the signals of the control device can be fed. Such resolvers are commercially available and mechanical as well as extremely thermally robust. Such a resolver is based on the rotary transformer principle built up. Commercially available resolvers are often with integrated evaluation circuit available, so that their signal can be fed directly to the control device.

In a further advantageous embodiment of the invention can be provided that the arrangement has an optical encoder for measuring the position and / or the speed and / or the acceleration of the movable furniture part comprises, whose signals can be supplied to the control device. Such optical or also Magnetic encoders provide a low-cost and often space-saving alternative to the resolvers dar. They still guarantee one for an inventive Arrangement satisfactory angular resolution range, for example, from 64 to 1024 Pulses / revolution. Certain disadvantages with optical and magnetic encoders arise from their sensitivity to mechanical vibration, contamination and the absence of absolute angle information at the time of turn-on, so that such encoders can only make incremental position determinations.

In a further advantageous embodiment of the invention it is provided that the Drive unit includes a brushless DC motor and measuring the position and / or the speed and / or the speed and / or the acceleration of the movable furniture part is done directly via the commutator signal, the like obtained signals can be fed to the control device. Frequently, such brushless Motors with Hall sensors running commercially available.

Nowadays electric motors are already available in miniature construction, in which a electronic, optical or magnetic position measuring device already in the electrical Engine is integrated, which saves both space and time during installation.

Fig. 12a shows a prior art rotatably mounted disc 23 from Conductive material that is part of a magnetic encoder, not shown, wherein the disc 23 rotatable about a shaft, not shown, with the drive unit. 5 connected is. Inductive sensors 27 which can be seen directly above one of the two surfaces of the disc 23 are arranged. Once the user has a Force exerts on the movable furniture part 3, not shown here, gets the with the Drive unit 5 related disc 23 in rotary motion, so that the inductive sensors 27, depending on whether they are conductive material of the Disc 23 or above an air gap, signals of the form shown in Fig. 12c forward to the control unit 1. By the embodiment shown in these figures as Two-channel decoder can span the width of each pulse between the two channels the rotational speed and the phase of the individual pulses, the direction of rotation of the Disk 23 and thus the associated with her drive unit 5 are determined and so be deduced to the linear movement of the movable furniture part 3. As soon as that is, the user sets the movable furniture part 3 in motion in any direction, this registers the control device 1 by the of the position measuring device 4, of the the disk 23 and the sensors 27 in this embodiment represent a part, outgoing electrical signals and gives the drive unit 5 via a intermediate drive unit controller 10 command to accelerate the movable furniture part 3 in the direction intended by the user. Fig. 12b shows a perspective view of the two components 23 and 27 of FIG. 12a. Fig. 12d shows Elements of a position measuring device 4 of a further embodiment, which in present case is designed as an optical encoder and here, of course, at the same time Acceleration measuring device 2 represents. Evident are light-emitting elements 25, whose light falls over a shutter 31 on light detecting elements 24, if not is interrupted by the intermediate rotating disk 23. The details Such measuring devices can be found in the relevant specialist literature.

By way of example, FIGS. 13a, 13b and 13c show, with the aid of travel-time diagrams, a typical actuation process in the course of which the movable furniture part 3 moves from its closed end position into an intermediate position in which it temporarily comes to rest and after renewed actuation the user is moved to the open end position or, alternatively, back to the closed end position. In this exemplary embodiment, it has been assumed by way of example of a total path S of approximately 0.43 m between the closed and the open end position. The closed end position corresponds to the ordinate origin zero in the path-time diagrams. In the embodiment as a touch-latch furniture, the closed end position of course corresponds to a position of the movable furniture part 3, in which a gap 30 remains between its front panel 31 and the front side of the arrangement according to the invention. It can now be seen in FIG. 13a that, within a first time span t _o, after actuation by the user, a uniform acceleration of the movable furniture part 3 by the drive unit 5 takes place via a partial branch S ₁ to support the opening movement. The subsequent movement of the movable furniture part 3 takes place only under the influence of the system-related friction, so that the movable furniture part 3 finally comes to rest in an intermediate position (here about 0.22 m). Fig. 13b shows a possible course in which the user after a certain time again train on the located in the intermediate position movable furniture part 3 exerts, whereby the control unit 1 via the drive unit controller 10 of the drive unit 5 the command for uniform acceleration of the movable furniture part 3 in Direction of the train acceleration granted. It can therefore be seen in Fig. 13b, a renewed uniformly accelerated movement of the movable furniture part 3 by the drive unit 5 over a section S ₂ , an intermediate movement alone under the influence of systemic frictional force, which leads to a certain deceleration of the movable furniture part 3, as well via a partial path S ₃ a new uniformly accelerated movement, this time the acceleration by the drive unit 5 of the instantaneous speed of the movable furniture part 3 is opposite and thus leads to a deceleration. As a result, the movable furniture part 3 comes to rest with negligible end speed or zero speed in the open end position. In other words, the partial path S _{3 is} a factory-set braking distance, which ensures a safe deceleration of the movable furniture part 3 during the transition to the open end position. For the user, this presents itself as a friction effect which is amplified in the area S _3. FIG. 13 c shows a likewise possible progression shape in which the user accelerates the movable furniture part 3 located in an intermediate position in the direction of the closed end position by pressure. To recognize in turn is the immediate onset supporting effect of the drive unit 5, which is reflected in the uniformly accelerated movement of the movable furniture part 3 over the section S ₂ in the path-time diagram. Also to be seen is a closed end position upstream protection path S ₃ , in which the drive unit 5 causes a uniformly accelerated deceleration movement of the movable furniture part 3, in order to transfer them safely and without unnecessary noise in the closed end position. It can be seen that the partial path between the partial paths S ₂ and S _{3 was covered} only under the influence of the system-related friction, which corresponds to the basic idea according to the invention. The partial paths S ₁ , S ₂ , S _{3 of} the entire path S between the closed and the open end positions shown in FIGS. 13 a, 13 b, 13 c are usually preset at the factory. This corresponds to the idea that the user does not want to be burdened with technical details. Of course, it could be provided that a technically more dedicated user sets the partial routes S ₁ , S ₂ , S ₃ or the time interval t _o , via which an acceleration takes place, within certain limits (ie taking into account safety aspects).

In Fig. 14 was shown schematically, in which way the individual components of inventive arrangement exchange information with each other. It can be seen schematically the control device 1, a drive unit controller 10 and a Istwertberechnungseinrichtung 8 includes. The position measuring device 4 can signals the actual value calculation device 8 pass and has even the possibility of signals from receive the initialization device 6, which in turn via actuators 20, 11, 9 is triggered. The drive unit controller 10 receives signals from the Acceleration measuring device 2 and the actual value calculating device 8. The schematic logical representation of the information flow between the system elements does not necessarily correspond to the physical arrangement of the same. For example All system elements can save space in an integrated design physically arranged in the arrangement 7 according to the invention. Often you can also in physical form individually present component several logical functions take over, as for example in resolvers and optical or magnetic Encoders is the case. These can simultaneously as position measuring device 4 and as Accelerometer 2 serve. From the angle of rotation of a disc optical or magnetic encoder, for example, the possibility arises on the one hand an incremental position determination and on the other hand only from the fact that the disk sets in rotation, as well as from the detected Speed change the possibility of measuring the acceleration.
