According to the invention, the monitoring unit is designed to render the automatic closing inoperative for positioning the first furniture part, in an open position, from which the first furniture part, returns automatically to a closed position after a predetermined closing time interval.

Description

The invention relates to a device for moving a first furniture part relative to a second furniture part according to the preamble of claim 1 and a piece of furniture.

State of the art

Devices for moving a first furniture part relative to a second furniture part with a drive unit have already become known in many embodiments from the prior art. An arrangement with a movable furniture part in the form of a drawer is for example in the European patent application EP 1 323 362 A1 disclosed. The arrangement comprises a drive unit for the drawer and a control device for controlling the drive unit.

From the German patent application DE 198 21 014 A1 a device for opening a closure element, such as a drawer, a door or a flap with a drive unit is known. An easy-to-actuate device is provided in that it has a drive unit and a trigger element, wherein the closure element includes the trigger element and the trigger element is designed such that in its Touch a signal is generated by the drive unit is driven directly or indirectly.

Furthermore, a device for moving a first furniture part relative to a second furniture part according to the preamble of claim 1 GB 2 374 521 A known.

Purpose and advantages of the invention

The invention has for its object to provide a device for moving a first furniture part relative to a second furniture part with a drive unit, which has an improved compared to the prior art operating functionality.

This object is solved by the features of claim 1 and 7.

In the dependent claims advantageous and expedient developments of the invention are given.

The invention relates to a device for moving a first furniture part relative to a second furniture part with a drive unit, by means of which it is driven by a control unit for controlling the movement of the first furniture part of this relatively movable to the second furniture part. The essence of the invention lies in the fact that the control unit is designed, for a positioning of the first furniture part in an open position, from which the first furniture part automatically returns to a closed position after a predetermined closing period, the automatic closing override , This approach is based on the finding that in certain applications it is disadvantageous if an automatic closing of the first furniture part takes place. For example, it is undesirable for a powered drawer to close automatically, although the user wishes to leave the drawer open for a longer period of time, for example, to allow it to be cleared, cleaned up, or cleaned. That out of power can be set by a preset program sequence, for example, with respect to time. That is, it is conceivable that at a given time of day, for example, a cleaning lady is working, the automatic closing never takes place. It is also possible that a control action overrides the automatic closing.

The control unit is designed, after a positioning of the first furniture part in an open position, from which the first furniture part automatically returns to a closed position after a predetermined closing period, to override the automatic closing by a control action within the predetermined closing period. This makes it possible, e.g. if necessary, leave an open drawer in its open position by an individual control action shortly after opening. If the furniture part, e.g. the drawer is then moved to the closed state by a manual release action, the control unit is preferably designed to neutralize the automatic closure again. This will automatically move the furniture part back to the closed state at the next initiated opening movement.

In a preferred embodiment of the invention, a control unit is provided in which a return to the closed position within the predetermined closing time period is overridden, if before the closing period, the first furniture part manually from the open position by a predetermined distance to another Open position is moved. For example, the movable furniture part is moved to an open position, which is located a small distance before the maximum possible open position. By manually opening the Furniture part in the "all-open position", the automatic closing process is then not initiated. In the case of a drawer, for example, this is conceivable such that the drawer automatically opens into a position a few millimeters before a maximum position, wherein the maximum position is preferably limited by a mechanical stop. Dragging the drawer to the mechanical stop overrides automatic closing.

Furthermore, it is preferred if the control unit is designed to leave the first furniture part in a further open position without further manual action there. This ensures that the furniture part remains in the open position until an operator causes the return to a different position, eg in a closed position. Alternatively, the control unit for specifying the movement of the first furniture part from the further open position to a third position after a period of time which is higher by a multiple than the predetermined closing period, designed. The third position is preferably the closed position. By doing so, it is avoided that furniture parts, especially a drawer unintentionally long open. For example, the furniture part, although the setting off of the automatic closing process after expiration of eg 15 minutes moved to another position, preferably closed.

The control unit may e.g. a micro-control control, which contains the monitoring device for controlling and controlling the movement of the first furniture part. It can be integrated in the drive. It is inexpensive to manufacture (mass-produced) and can be programmed for the existing system.

The invention also relates to a piece of furniture with furniture parts which are movable relative to one another and which comprises one of the aforementioned devices. This can be achieved with the respective device achievable advantages for a piece of furniture with relatively movable furniture parts. In particular, the furniture comprises movable furniture parts such as e.g. Drawers, doors, flaps and the like, which are movably guided by suitable guide means on a second furniture part, in particular a furniture body. As guide means come for drawers in particular guide rails or for doors or flaps in particular fittings or hinges in question.

in a highly schematic side view of another embodiment of a body with three according to the invention driven drawers.

Description of the embodiments

In FIG. 1 obliquely from above a piece of furniture is shown, which comprises a body 1 and a movable therein drawer 2. The arranged in the lower part of the body 1 drawer 2 is shown in the open or retracted state, wherein the mutually movable furniture parts 1 and 2 against each other via a pull-out 3 are displaced, which by a drive (in FIG. 1 not apparent, see in particular FIG. 2 ) is pressed. In the body 1, a further, not shown drawer for a further drawer slide 3a can be accommodated in the same way. The drawer 2 is movable according to the double arrow P1 relative to the body 2. For holding or guiding the movement of the drawer 2, the drawer guides 3, 3 a are connected to lateral drawer 2 a. Actuators preferably act directly on the drawer guides 3, 3a. However, it is also conceivable that a drive on the drawer itself, here attacks on the back of the drawer, as in FIG. 2 symbolically represented. Then, a conventional drawer guide 3 can be used.

The drawer 2 is after it has reached an open position driven to remain in this, but automatically return to the closed state after a predetermined closing period.

Preferably, for this purpose, the drawer 2 is first pulled against an end face 1a and then positioned with some distance in front of the end face 1a, so that between a rear side of a drawer front 2b and the end face 1a, a gap is formed.

This process is in FIG. 2 illustrated. In this embodiment, 20 drawers 21, 22, 23 are arranged in a body. The drawer 22 is pulled completely against an end face 20a of the body 20, the actual closed position being defined slightly away from the end face 20a. This positioning is shown with the drawer 23. However, the closed position can also be defined by the system of the respective drawer 21, 22, 23 on the end face 20a.

The drawers 21, 22, 23 are driven by drive elements 24, 25, 26, e.g. Train-pressure cable and electric motors 27, 28, 29 driven. The drawers are preferably driven in a range of movement between an open position and a closed position. The opening position is preferably set to be a small distance 30 before a maximum opening position X. The maximum opening position X is conveniently defined by a mechanical stop of the drawer guides 31, 32, 33.

A normal process looks like this:

By a trigger action of an operator moves the drawer, such as the drawer 21 automatically in a position "X-distance 30". If no further control action is taken by the operator, eg a manual tap, the drawer 21 moves automatically after an expired closing period of eg 10 seconds to a closed state corresponding to the position of the drawer 22 or 23. On the other hand, does an operator pull the drawer 21 over the position "X-distance 30" further out, if necessary, up to the mechanical stop at the point X, the automatic closing sequence is overridden. The drawer 21 preferably remains there until they are manually from a Operator is pushed in the closed position. In the locked "open position" of the drawer can then, for example, work such as cleaning, clearing, clearing out or other operations that take a long time to perform without an operator is disturbed by an automatic closing of the drawer.

The override of the automatic closure can also be overridden by other control actions that need not necessarily be performed within the given conventional closing time span.

However, these are preferably manual control actions of an operator from the outside.

However, it is also conceivable that is already predefined in a control unit, while e.g. a predetermined period of time, in principle, the automatic closing override.

Preferably, however, such internal parameters of the control unit can be changed.
