Description

The invention relates to a piece of furniture with a furniture body, in which at least one drawer is provided, which is displaceably guided in the piece of furniture between a pushed out of the furniture body open position and an inserted into the furniture body ready position, with a drawer drive for at least partially extending and / or retraction the at least one drawer and with a control unit for controlling the drawer drive of the at least one drawer as required.

Drawers are indispensable containers in all areas of life. In a configured as a box or cabinet furniture usually several drawers are installed. These drawers can be completed either individually or inexpensively centrally on the piece of furniture. When a drawer is pulled out of the piece of furniture, it must generally be prevented that another drawer of the same piece of furniture can be opened, as long as one drawer is open, as the piece of furniture can tip over when the drawer is fully extended. For the industrial sector is looking for a way to open and lock in to make the handling easier and to be able to capture the state of the drawers and their number centrally. The discussion on this topic is also led by the keywords "Industry 4.0", "Condition Monitoring" or "Chaotic Storage". It is also desirable to assign each drawer in a piece of furniture a separate authorization to open, so that only those drawers can be opened for which the legitimacy exists. This legitimization can be a code word to be entered via a keyboard, an RFID card, a fingerprint or a radio signal.

There are also pieces of furniture on the market with a central drawer lock. This central drawer lock can either unlock all drawers or lock all drawers. When inserting the drawers, the retraction speed is slowed down by a pneumatic damper shortly before the insertion end. When opening a spring force over a range of a few centimeters must be overcome when pulling out the drawer, the corresponding spring then reversed when inserted serves to finally pull the drawer into its inserted standby position in the furniture body. Cabinets with individually lockable drawers require a separate key for each drawer, preventing more than one drawer from being pulled through a mechanical lock.

With the systems on the market, the desired objective of the condition detection, the insertion damping, the motorized extension of the drawer and a legitimation process without the use of multiple keys can not be economically represented. In addition, the damping function is in particular a pneumatic damper of the Drawer loading dependent.

There is therefore a particular object to provide a piece of furniture of the type mentioned, in which the insertion of a drawer is adaptively damped independently of the drawer load and in which a control of the at least one drawer associated drawer drive can be accomplished in a simple manner advantageous.

The inventive solution to this problem is in the piece of furniture of the type mentioned in particular that the drawer drive has a slide control with a run in a slide track slider, which slide control converts the rotational movement of a drive motor of the drawer drive in a linear movement of the furniture body displaceably guided drawer.

The piece of furniture according to the invention has a furniture body, in which at least one drawer and preferably a plurality of drawers are provided. These drawers are in the piece of furniture between an ejected from the furniture body open position in which can be accessed on the drawer contents, and a readiness position displaced, in which the drawer is inserted into the furniture body. Each of the drawers provided in the piece of furniture is a drawer drive, in particular associated with an electric motor drive motor, which is intended for at least partially extending and / or retracting the at least one drawer. By retracting the drawer with the aid of the drawer drive, the retraction movement of the drawer in the direction of its ready position can be adaptively damped independently of the loading of the drawer. By a motorized extension of a particular drawer, the user with the required Drawer contents loaded drawer displayed and the handling of this drawer when pulling out of the furniture body to be facilitated. For controlling the drawer drive of the selected drawer, a control unit is provided. The drawer drive has a slide control with a run in a slide track sliding element, which slide control converts the rotational movement of a particular electromotive drive motor of the drawer drive in a linear movement of the movably guided in the furniture body drawer. About the drawer drive and the gate control, the movement speed and the damping of the drawer in the direction of its open and / or ready position can be easily controlled in a simple manner.

While the pull-out of a drawer is to be completed as quickly as possible, is sought in the retraction of the drawer in the ready position that slows down the sliding movement of this drawer towards standby position so that the drawer enters steamed in this standby position. A development according to the invention therefore provides that the movement of the sliding element is selected in the slide track so that the drawer in the controlled by the drawer drive portion of the sliding path in the open position or in the standby position in an approximate position ready position an increasingly lower sliding speed has, in comparison to a contrast to the open position approximated sliding position of the drawer.

In this case, an embodiment is preferred in which the controlled by the drawer drive speed change during the sliding movement of the drawer of a cosine-square function follows.

Thus, the at least one drawer can be secured against unauthorized access in the standby position and thus only one drawer with appropriate legitimacy can be moved from the ready position to the open position, while the other drawers of the furniture remain in the standby position, it is advantageous when the at least one drawer is securable by means of the drawer drive in the standby position.

In order to convert the rotational movement of a drive motor into a linear movement of the drawer, the drawer drive can have a threaded spindle, the spindle thread of which forms the slide track, in which sliding track, the sliding element moves. If the spindle thread is not formed linearly, the sliding movement of the drawer can be controlled during the pulling-in or pulling-out process. If the non-linear spindle thread is designed to be self-locking in its threaded part region corresponding to the ready position, the drawer can no longer be pulled out manually from the ready position without further ado.

However, a preferred simpler embodiment according to the invention provides that at the at least one drawer, a catch element is held, which carries the slide track.

This catching element can be designed, for example, as a catch plate preferably arranged on the underside of the drawer. If this catch plate is designed resiliently in the plane oriented transversely to the slide track, the catch plate in the slide track of its slide control during the retraction movement of the drawer, the slider catch and release the sliding element again during a pull-out movement of the drawer from the slide track.

To pull the drawer over a larger portion of its sliding path manually and without regard to the drawer drive in the direction of the open position or to be able to enter the ready position, it is expedient if the catch element in an oriented between the open position and the ready position intermediate position with the slider detachable connectable, in particular releasably latched, is.

The desired in the standby position portion of the sliding path speed change follows in a simple manner the preferred cosine-square function when the slider is rotatable by means of the drive motor part-circular or curved in the drawer drive.

For this purpose, a preferred embodiment according to the invention provides that the sliding element is guided in a part-circular or curved guideway.

A preferred embodiment according to the invention provides that the guideway of the sliding element is subdivided by the dead center of its pitch circle or curved shape into a drive section and a securing section, in which securing section of the guideway the drawer is in its against a motorless pulling out of the drawer secured standby position.

In this case, a particularly simple embodiment according to the invention provides that the guideway has a closed tail in its securing portion.

So that the sliding element can transmit the driving force of the drive motor located in the drawer drive via the slotted guide to the drawer, it is advantageous if the sliding element is in drive connection with the drawer drive.

So that the drive motor in the drawer drive can transmit a sufficient driving force to the drawer, it is advantageous if a transmission and preferably an angular gear, in particular a bevel gear, is provided in the drive connection between the sliding element and the drawer drive.

In order to not unfavorably also transfer to the drive motor of the drawer drive when sliding the drawer intermittent trapping of the sliding element in the slotted guide, it is advantageous if in the drive connection between the slider and the drawer drive, a damping unit is provided which the intermittent snapping of the sliding element in the slide track against the drawer drive dampens.

In this case, a preferred embodiment according to the invention provides that this damping unit has at least two cooperating clutch discs, of which a first clutch disc preferably carries the first clutch disc protruding sliding member, and that a second clutch disc is in drive connection with the drive motor.

It is advantageous if the first and the second clutch writing are rotatably engaged relative to each other by a rotational angle and when the engagement between the clutch discs in at least one direction of rotation and preferably in both directions of rotation to the lying in the direction of rotation end of the rotation angle is rubber or spring-elastic damped. Since the clutch discs are in engagement with each other, a rotational movement of the drive motor via the clutch discs of the damping unit can be transferred to the guided in the slotted guide and rotatable in its guide slide. However, the clutch discs are not rotatably engaged with each other, - but the clutch plates are rotatable relative to one another by a rotational angle, in such a way that the engagement between the clutch discs in preferably both directions of rotation to the lying in the direction of rotation end of the rotation angle rubbery or resilient is muted.

In order for the control unit to be able to set the drive motor of the drawer drive in motion, it is advantageous if the control unit is in control connection with at least one displacement sensor which detects a movement impulse or a movement of the drawer and / or a movement impulse or a movement in the drive connection between the sliding element and registered the drawer drive.

As such a displacement sensor can also serve the drive motor, when this drive motor converts a rotary motion on its motor shaft into a current pulse. In addition to or instead of the drive motor serving as a travel sensor, however, at least one travel sensor separate from the drive motor can also be provided. Such a separate displacement sensor can be designed, for example, as a Hall sensor.

It is advantageous if the control unit triggers the drawer drive as soon as the at least one displacement sensor registers a movement or a movement pulse on the drawer.

In order for the user to be able to display a specific drawer by slightly extending this drawer out of the furniture carcass, it is advantageous if the drawer drive of the at least one drawer can also be controlled arbitrarily via the control unit.

A preferred application provides that the piece of furniture has a plurality of drawers, to each of which a drawer drive is assigned, and that the drawer drives of the drawers can be controlled separately from one another via the control unit.

Further developments according to the invention will become apparent from the claims in conjunction with the figures and the description. The invention will be described in more detail below with reference to a preferred embodiment.

In the Figures 1 and 2 a drawer 1 is shown. The drawer 1 is provided in the furniture body, not shown, for example, designed as a tool cabinet piece of furniture. Such a piece of furniture regularly has a plurality of such drawers 1. These drawers 1 are in the piece of furniture between a pushed out of the furniture body open position in which can be accessed on the drawer contents and a standby position guided displaced, in which the drawer 1 is inserted into the furniture body.

Each of the drawers 1 provided in the piece of furniture is associated with a drawer drive 2 with a preferably electromotive drive motor 3, which is intended for at least partially extending and / or retracting the at least one drawer 1. By retracting the drawer 1 by means of the drawer drive 2, the retraction movement of the drawer in the direction of its standby position can be adaptively damped independently of the loading of the drawer. By means of a motorized extension of a specific drawer, the drawer 1 loaded with the required drawer contents can be displayed to the user and the handling of these drawers 1 when pulling out of the furniture body can be facilitated.

For controlling the drawer 1 associated drawer drives 2, a control unit not shown here is provided. From a comparison in particular the FIGS. 3 to 7 It is clear that the drawer drive 2 a slide control with a slide track 4 and a in the Sliding track 4 guided slide 5 has. The slide control sets the rotational movement of the drive motor 3 in the drawer drive 2 in a linear movement of the drawer movably guided in the cabinet body 1.

In the Figures 3 . 5 and 6 it can be seen that the sliding element 5 can be moved in a part-circle or curved guideway 6. This part-circular or curved movement of the sliding element 5 in the guideway 6 of the thrust carriage drive 2 is converted into the slide track 4 of the slide guide in a linear movement, wherein the slide track 4 is formed as a transverse to the linear sliding movement of the drawer 1 oriented slot.

By guided in the sliding track 4 sliding element 5, the drawer 1 in the controlled by the drawer drive 2 portion of the sliding path in the open position or in the standby position in a ready position approximated position on an increasingly lower sliding speed, compared to a contrast to the open position of Drawer 1 approximate sliding position. As a result of the partial circular or curved movement of the sliding element 5 guided in the slide track 4, the speed change controlled by the drawer drive 2 during the sliding movement of the drawer 1 preferably follows a cosine-square function.

In FIG. 7 the drawer drive is shown in a position corresponding to the ready position of the drawer 1. How out FIG. 7 becomes clear, the at least one drawer 1 of the furniture by means of the drawer drive 2 in the standby position securable. Out FIG. 1 It is clear that on the underside of the drawer 1, a catch element 7 is mounted, which here designed as a catch plate is. The catch element 7 carries the slide track 4 of the slotted guide. In order to capture the slider 5 during a retraction of the drawer in the slot formed as a slot track 4 and to release the slider 5 during a pull-out of the drawer 1 from the slide track 4 of Fangelements 7 again, the catch element 7 is in the transverse to the slide track 4th oriented plane resiliently trained. Side of the Fangelements 7 are on both sides bump guides 8, which cooperate in both sliding directions of the drawer 1 with bevels 9, which are provided on both sides of the catch element 7. When the ramps 9 are moved over the buffing guides 8, the elastic catching element is raised so that it can catch the sliding element 5 with the slide track 4. Even in a rebounded position of the catching element 7, a securing element 10 made of sheet metal, with its sliding edge 5 facing the guide element 5, abuts on the sliding element 5. Catch element 7 and securing element 10 are connected to one another and mounted on the underside of the drawer 1. The guide element 6, which guides the sliding element 5 during its rotational movement, is in the form of a partial circle or a curve. This guide track 6 is subdivided by the dead center 11 remote from the drawer 1 into a drive section 12 and a securing section 13, in which securing section 13 of the guide track 6 the drawer is in the in FIG. 7 shown and secured against a motorless pulling out of the drawer 1 ready position is. The guideway 6 has a closed tail 14 in its securing portion 13. While the catch element 7 is mounted together with the securing element 10 on the underside of the drawer 1, the remaining components of the drawer drive in the furniture body of the piece of furniture -, preferably held on the rear wall of the piece of furniture.

In the FIGS. 4 . 8th and 9 is particularly clear that the sliding member 5 is in drive connection with the drawer drive 2. In this drive connection, a bevel gear 15 is provided. In addition, a damping unit 16 is provided in the drive connection between the sliding element 5 and the drawer drive 2, which damps the intermittent catching of the sliding element 5 in the slide track 4 on the catch element 7 with respect to the drive motor 3. This damping unit 16 has two mutually cooperating clutch plates 17, 18, of which a first clutch sprocket 17 carries the first clutch plate 17 protruding sliding member 5 and a second clutch disc 18 is formed as a bevel gear meshing with a bevel pinion 19 on the motor shaft of the drive motor 3 ,

In FIG. 10 it can be seen that the first and the second clutch plate 17, 18 are rotatable about a rotational angle relative to each other in engagement. Since the clutch plates 17, 18 are engaged with each other, rotational movement of the drive motor 3 is converted into a partial circular or curved rotational movement of the sliding element 5 projecting above the first clutch plate 17. However, the clutch plates 17, 18 are not rotatably engaged with each other, - but the first and the second clutch plate 17, 18 rotatable about a rotational angle relative to each other into engagement, wherein the engagement between the clutch plates 17, 18 in preferably both directions of rotation to the in Direction of rotation lying end of the rotation angle is attenuated resiliently by means of damping springs 20.

The standing in control connection with the drawer drive 2, but not shown here further control unit is connected to a displacement sensor, which is a motion pulse or a movement the drawer 1 and / or registered a movement or a movement impulse in the drive connection between the sliding member 5 and the drawer drive 2. As a displacement sensor can also serve the drive motor 3, when this drive motor 3 converts a rotational movement applied to it into a current pulse. In addition or instead of the drive motor 3 serving as a displacement sensor, at least one separate displacement sensor can be provided which registers such a motion pulse. In FIG. 3 At least one designed as a Hall sensor displacement sensor 21 is provided, which cooperates with a arranged in the region of the chamfers 8 on the catch element 7 magnet 22. The control unit triggers the drawer drive 2 and its drive motor 3 when the at least one displacement sensor 21 registers a movement or a movement pulse. If it is registered by such a displacement sensor 21 that the drawer moves into the shift end position corresponding to the standby position, the control unit sets the drive motor 3 in motion, which generates a counterforce which counteracts an excessive sliding movement. The drawer drive 2 shown here is designed and constructed so that it can be damped when inserting the drawer 1 adaptively and thus independent of the drawer load. In this case, the state of the drawer 1 and its position during the sliding path via the displacement sensors 21 is detected. By briefly touching or pulling the drawer 1 in the closed state and the associated motion impulse the information "I want to be opened" is transmitted to the control unit, which also realizes the mechanical "multi-drawer pull-out prevention". As an indicator for a subsequently extendable drawer 1, the relevant drawer 1 is moved out by motor, for example, 4 cm by means of the drawer drive 2, so that the user then completely pull out the drawer 1 by hand can. During motor extension and retraction of the drawer 1, a speed profile is driven with the aid of the drive motor 3, which corresponds to a cosine square function. The speed profile ensures a constant acceleration both when braking and when moving out of the drawer 1. This avoids excessive accelerations, which could jumble and damage the drawer contents.

The drawer drive takes over here the function of damping when inserting the drawer 1, pulling the drawer 1 in the locked ready position, detecting the opening request expressed by a motion pulse and the extension of the drawer by, for example, 4 cm as information for the state "open" or "released for opening".

Since the drawers 1 can be loaded with a wide variety of weights, an adaptive damping is sought here. When inserting the drawer 1 should - largely independently of the located in the drawer 1 mass - the drawer 1 always be controlled in speed so that then a continuous retraction of the drawer 1 can be done.

Once in the piece of furniture one of the drawers 1 is opened by a motor, is prevented by a logical link provided for the other drawers drawer drives in the control unit that a further drawer 1 can be pulled out. It also ensures that no more drawers 1 are open. This is important because otherwise this piece of furniture could tip over due to the displacement of all masses out of the furniture body of the piece of furniture.

If the piece of furniture requires separate credentials for its drawers 1, it is necessary to display the drawer 1 assigned to this legitimation once the legitimization has been detected. This can be in the simplest case a numeric display with the identification number of the drawer 1 as information or a side of the piece of furniture in the amount of the respective drawer 1 provided signal lamp. It would be technically more complicated to accommodate a corresponding signal lamp in the respective drawer 1 itself. Another possible method for displaying the legitimacy associated with drawers 1 may also provide by a short motorized method of the relevant drawer. Thus, the assigned drawers 1 after legitimacy detection, for example, each extended by 5 to 10 mm and the visual recognition of this assignment would be completely sufficient even if the drawers 1 are immediately moved back motorized.
