Description

The invention relates to a corner cabinet, in particular Kücheneckschrank, with a carousel, which is rotatably mounted on the corner cabinet about a Drehachslinie, wherein the carousel has a fitting on which at least one corner cabinet door is mounted such that the corner cabinet door between a cabinet opening of the corner closures closing position and a rotational position permitting rotation of the corner fitting.

A corner cabinet of this kind is for example from the DE 30 49 114 A1 in which a fitting is provided, which carries a two-leaved door. In order to make the inside of the cabinet accessible, the two door leaves are pushed inwards into the open position for opening. The two door leaves are free from the side walls of the corner cupboard so that the carousel can be rotated in the corner cupboard without the door wings touching the side walls.

Particularly in the case of corner cabinets with large door dimensions or heavy-weight corner cabinet doors, opening the corner cupboard is associated with a not inconsiderable expenditure of force. Also, the rotation of the carousel requires, in particular depending on the weight of parked on the shelves objects also a considerable effort.

The object of the invention is to provide a corner cabinet of the type mentioned, which can be opened and operated comfortably and easily.

This object is achieved by a corner cabinet with the features of independent claim 1. Further developments of the invention are shown in the subclaims.

The corner cabinet according to the invention is characterized in that an actuating device is provided which has an activatable via activating actuator, which moves the corner cabinet door at least in the open position when activated.

The opening of the corner cupboard can therefore take place automatically without the corner cabinet door having to be pushed inwards manually by the user. Thus, a comfortable and smooth operation is possible.

Conveniently, the rotation of the carousel is supported by the actuator. In this case, the actuating device can be designed such that the corner cabinet door by means of the actuator beyond the open position in a, a certain rotational position of the fitting associated intermediate position is movable. From this intermediate position then a further rotation can be done by hand. The carousel can thus already get a start-up angular momentum, so that a further rotation by hand is easier.

Alternatively, it is possible that the actuating device is designed such that the complete rotation of the carousel is taken over by the actuating device. If the carousel at a certain point to be stopped, this is by a short manual intervention in the twisting movement possible, for example by a handle on the tray.

In a further development of the invention, the actuator has at least one drive member connected to the fitting, in particular its control linkage, or to the corner cabinet door or to a tray via conversion means, whose drive movement is converted via the conversion means into an adjusting movement acting on the carousel.

In a particularly preferred manner, the actuator is an electric actuator with at least one electric drive member. In principle, however, would also be the use of a fluidic actuator with at least one fluidic drive member, for example in the form of a single or double-acting fluid pressure cylinder, possible.

In the case of an electric actuator, the electric drive member is preferably formed by an electric motor. Preferably, a gear is associated with the electric motor.

In a further development of the invention, the fitting on a connected via a steering linkage with the corner cabinet door guide means which serves to guide the carousel during its rotation. The guide device has a stationary guide track extending concentrically to the axis of rotation axis and a guide means running on the guide track, which in the closed position of the corner cabinet door is mounted in a guide recess, preventing rotation of the carousel. The guide means may be coupled to the actuator via the conversion means such that, upon activation of the actuator, it may be disengaged from the guide recess, permitting a rotation of the carousel, is moved out. The guide means may be formed for example by a guide roller.

In a preferred manner, the transfer means have a lever arrangement coupled on the one hand with the actuator and on the other hand with the guide means. In a particularly preferred manner, the lever arrangement may comprise at least one coupled to a rotationally driven drive shaft of the associated drive member of the actuator pivot lever which moves out the guide means of the guide recess in the manner of a driver during its pivotal movement. The rotational drive movement of the drive member can thus be converted into a pivoting movement of the pivot lever, which ensures that the guide means is moved at least in a corresponding to the open position of the corner cabinet door functional position. Alternatively, other lever arrangements, such as those with multi-part levers, can be used or the lever kinematics can also work differently. In principle, it would be conceivable that by means of the lever arrangement a rotational drive movement of the drive member is converted into a linear movement, with which the guide means can then be moved out of the guide recess.

In a particularly preferred manner, the actuator is below a cabinet bottom of the corner cabinet, in particular attached to the underside of the cabinet floor, arranged. In general, the corner cabinet is on a console or on feet, so that between the bottom of the cabinet floor and the ground, a gap is formed, which can be used to accommodate the actuator. The actuator is thus space-saving, hidden from view of the user. Alternatively, it is also conceivable to the actuator to arrange the bottom of the cabinet or underbody. Another possibility is to attach the actuator to the fitting, for example, to integrate a trained as a tubular motor drive member in a hollow tube-like rotary column of the corner cabinet. Alternatively, the arrangement of the actuator at the bearing cross of the corner cupboard, on the corner cupboard itself or below a tray conceivable. In principle, the actuator can be mounted anywhere on the corner cabinet, hereby necessary are suitable Umsetzmittel that can transmit the drive movement of the actuator to the carousel.

In the aforementioned possibility of attachment to the underside of the cabinet bottom can be located in the bottom of the cabinet at least one opening through which pass a part of the Umsetzmittel up to the above the cabinet floor arranged guide roller.

In a development of the invention, at least one sensor is provided as activation means, the sensor signal of which can be transmitted directly or via a control unit to the actuator. In a preferred manner, the signal transmission takes place wirelessly. Alternatively, however, a cable-controlled signal transmission would be possible. Activation of the sensor can also be done remotely. It is possible to activate the actuator directly by remote control without the intermediary sensor.

The sensor sits in a preferred manner easily accessible by the user at the corner cupboard periphery of the corner cupboard. In a particularly advantageous manner, the sensor is formed by an actuatable by means of pressure pulse pressure sensor, which can be arranged such that the pressure pulse can be generated by pressing on the corner door. The user So just needs to gently tap the corner door, which activates the sensor and activates the actuator. When selecting the sensor, the entire range of sensor types is available, for example, instead of the pressure sensor, an acoustic voice input responsive sensor can be used. It is possible to use a so-called touch sensor, which can be activated by contact by the user.

In the above-mentioned possibility to perform the complete rotation of the carousel by the actuator, it is expedient to provide the actuator functionally downstream rotational drive, which takes over the further movement of the carousel from a certain rotational position. The stopping of the carousel can be done by hand. For example, this can be realized constructively in that the torsion drive is provided with a clutch, so that when stopped by hand, the drive movement of the torsion drive is no longer transmitted to the carousel. The further movement of the carousel can then be done by a short angular momentum by hand in the direction of rotation. In the combination of actuator and Verdrehantrieb may be provided to ensure a manual operation of the carousel in case of failure of the actuator and / or Verdrehantriebs a safety device.

In a further development of the invention, the actuator has two drive links, one of which serves to move the carousel in the clockwise direction and the other to move in the counterclockwise direction.

The FIGS. 1 to 13 show a preferred embodiment of the invention Eckschranks 11 a fitted kitchen. This contains a carousel 12, which is formed by a fitting 13, at least one tray 14 or shelf and a corner cabinet door 15, wherein the at least one tray 14 and the corner cabinet door 15 are held by the fitting 13. Preferably, the corner door 15 is formed by two separate door leaves 15a, 15b, which are movable relative to each other when opening in the manner described in more detail below. Alternatively, it is possible to provide two door leaves 15a, 15b which do not change their relative position to one another when they are opened, That is, in particular always aligned at right angles to each other and are driven in this angular position and radially inwardly into the open position.

The fitting 13 has a in-use position, that is, in the corner cabinet 11 installed state, vertically aligned column (not shown), which is stored at the top of the example formed by a worktop cabinet cover and the bottom of the cabinet 16. The column may be formed as a central, to a Drehachslinie 17 coaxial rotary column. Alternatively, it is possible to use a U-shaped column, which could also be referred to as a carousel frame, wherein here horizontally extending bearing arms are rotatably mounted on the cabinet bottom or on the cabinet cover.

The corner cupboard 11 further has an overhanging cabinet opening 18, which is assigned to one of the two previously mentioned door leaves 15a, 15b and thus double-leaf door. In an alternative, a corner door 15 may be provided, which consists of a single door element which extends across the cabinet opening 20, this closing in the closed position extends.

The fitting 13 has a arranged on the rotary column support means for holding the two door leaves 15a, 15b. This support means includes an upper support member and a lower support member 19 which are arranged in column longitudinal direction at a distance from each other and fixed to the rotary column. The support elements 19 may each be arranged below a shelf 14. The lower support member 19 is associated with a steering linkage 20, with which the door leaf movement is controlled when opening and closing. The steering linkage 20 includes two steering levers 21a, 21b, which extend on either side of the pivot column and each one of the door wings 15a, 15b assigned. The steering levers 21a, 21b are pivotally connected to a fastening part 22a, 22b on the door side, which is fixed to the inside of the relevant door leaf 15a, 15b. The fastening parts 22a, 22b are also each pivotally mounted on the lower support element 19 via an axis of rotation. The steering levers 21a, 21b are connected at the far end of the door with a guide means 23 in the form of a guide roller, which also has a concentric to the rotary column, circular peripheral guide surface, which is fixed to the corner cabinet 11, in particular at the top the cabinet bottom 16 is arranged. In this case, the guide surface 25 is formed in the embodiment of the inner surface of a fastened to the bottom of the cabinet 16 annular body 26. The guide surface 25 is arranged at the level of the guide roller. It is interrupted at the point where the guide roller is in the closed position of the door. At this point, there is an outgoing from the periphery of the disk body guide recess 27 in the annular body 26, the width of which corresponds approximately to the diameter of the guide roller, so that it can engage in the guide recess 27. In the closed position, the guide roller dips into the guide recess 27, so that it and thus the carousel 12 is fixed in the circumferential direction.

The corner cabinet 11 may further comprise a damping device 28 for damping the closing movement of the corner cabinet door 15, wherein the damping device 28 may be arranged between two in the door movement relative movement to each other executing fitting parts of the fitting 13. This may for example be between the lower support member 19 and one of the two steering levers 21a, 21b.

The corner cupboard 11 also has an actuating device 29, which has an activatable via activating actuator 30, which moves the corner cabinet 15 at least in the open position when activated.

The actuator 30 is located according to the preferred embodiment below the cabinet floor in the intermediate space formed by a console between the bottom of the cabinet bottom 16 and the ground. The actuator 30 is attached to the underside of the cabinet bottom 16. It is equipped as an electric actuator with at least one electric drive member 31, which in turn includes an electric motor 32 with associated gear 33. The drive member 31 further includes a rotatably driven drive shaft 34 which dips into a located on the bottom of the cabinet 16 through opening 35 upwards. The actuator 30 has, according to a preferred embodiment, two electric drive members 31a, 31b, which are arranged on the left and right, in particular a mirror image of the rotary axis line 17. The two drive members 31a, 31b are constructed identically and perform substantially the same function, so that for simplicity in the following only one of the two drive members 31a, 31b is explained in more detail in structure and function.

The electric motor 32a, 32b rotatably drives the drive shaft 34a, 34b via the associated transmission 33a, 33b. The drive shaft 34a, 34b is connected to a socket-like extension tube 36a, 36b inserted over this, which for its part protrudes upward from the passage opening 35a, 35b of the cabinet bottom 16. The extension shaft 36a, 36b is part of conversion means via which the rotary drive movement is ultimately transmitted to an adjusting movement of the carousel 12 described in more detail below. To the conversion means Furthermore, still a lever assembly 37, whose main component is a connected to the extension shaft 36 wing-like pivot lever 38a, 38b, which can be pivoted by rotation of the extension shaft 36a, 36b back and forth. The pivot lever 38a, 38b extends substantially parallel to the top of the cabinet bottom 16 in the direction of the guide roller ( FIG. 10 ).

As in particular in FIG. 3 the guide roller is shown engaged behind by the pivoting lever 38a, 38b and, in fact, the end of the pivoting lever 38a, 38b projects beyond the central longitudinal axis of the guide roller, if this is located in the guide recess 27.

At least one sensor 39a, 39b in the form of a pressure sensor, which is preferably fastened to the inside of the side wall 21a, 21b of the corner cupboard 11, serves as activating means for activating the actuator 30. Again, two sensors 39a, 39b may be provided, wherein one of the sensors 39a on the left and the other sensor 39b on the right side wall 40a, 40b of the corner cupboard is arranged. Between the inside of a respective door leaf 15a, 15b and the end face of the associated side wall 40a, 40b is a narrow gap, for example with a gap width of 1 mm to 3 mm. The sensor 39a, 39b is now placed in such a way that a pressure member 41a, 41b of the sensor protrudes beyond the horizontal formed by the extension of the end face. By pressure on the outside of the door leaf 15a, 15b, this can be moved in the direction of the end face of the side wall 40a, 40b, whereby the pressure member 41a, 41b of the sensor 39a 39b operated and a sensor signal is generated.

As in particular in FIG. 17 As shown, the sensors 39a, 39b are preferably coupled to the actuator 30 via an internal or external controller. The signal transmission from the sensor to the control unit 42 and from the control unit 42 to the actuator 30 is wireless.

FIG. 1 shows the corner cabinet 11 with the corner door closed 15. To access the inside of the cabinet taps the user short by hand on the outside of the door, either on the left or on the right door 15a, 15b. As a result, the pressure member 41a, 41b of the sensor 39a, 39b is actuated, whereupon the sensor emits a sensor signal. This sensor signal passes via the control unit to the actuator 30, in particular depending on the actuated sensor either on the left or right drive member 31a, 31b. Thereafter, the electric motor 32a, 32b is started, whereby the drive shaft 34a, 34b is rotationally driven. This rotational movement is transmitted via the extension shaft 36a, 36b on the pivot lever 38a, 38b of the in FIG. 3 shown starting position is pivoted in the counterclockwise direction. The guide roller is taken and pushed out of the guide recess 27 and indeed into the in FIG. 13 shown position corresponding to the open position of the corner cabinet door 15. By the coupling of the guide roller 23 via the steering linkage 20 to the door wings 15a, 15b perform a mirror image with respect to the bisector 43 of Türecks movement, consisting of a the angle between the two leaves 15a, 15b shrinking folding movement and a superimposed this Einfahrbewegung along the bisector 43 composed. During this movement, the door leaves 15a, 15b pass further into the door opening, which, at least as far as it is necessary for the immersion of the door leaves 15a, 15b, also of other Sharing is free. Because of this Einklappbewegung with superimposed retraction, the two door leaves 15a, 15b of the side walls 21a, 21b of the corner cupboard 11 are free. The carousel 12 can now turn in the corner cabinet 11, without the door wings 15a, 15b on the side walls 40a, 40b stripes. According to the first embodiment, the pivot lever as soon as in FIG. 13 shown position of the guide roller 23 is returned by switching the electric motor 32a, 32b to its original position. The rotation of the carousel 12 can then be carried out by hand.

The FIGS. 13 to 16 show a second embodiment of the invention. Here too, a signal is transmitted to the associated electrical drive member 31a, 31b via the sensor 38a, 38b, whereby the pivot lever is moved from its in FIG. 3 shown starting position is pivoted in the counterclockwise direction. In this case, in turn, the guide roller is moved out of its guide recess 27 which leads to the above-mentioned Einklappbewegung the two door leaves 15a, 15b. In contrast to the first embodiment, however, the pivot lever 38a, 38b on the in FIG. 13 swung out shown position, whereby the guide roller comes into contact with the guide surface 25, so the carousel is so far twisted over the actuator a piece. The extent to which the carousel 12 is twisted depends inter alia on the length of the pivot lever 38a, 38b, because ultimately the guide roller at the end of the pivot lever 38a, 38b runs down therefrom, whereby guide roller and pivot lever 38a, 38b are out of contact from this point onwards. Alternatively, however, it would also be possible to specify the pivoting travel of the pivot lever 38a, 38b and to pivot the pivoting lever 38a, 38b back again after reaching a predetermined end position. At this Variant, the carousel 12 so by means of the actuator 30 a piece of momentum can be taken. After completion of the assumed by means of the actuator 30 rotational movement, the carousel 12 can then be rotated by hand on.

Finally, in a third non-illustrated embodiment of the invention, the complete rotation of the carousel 12 can be performed by a motor. In this case, for example, a combination of actuator 30 and a rotary drive, which takes over the further movement of the carousel 12 after completion of the rotation performed by the actuator. In this variant, the carousel 12 can be stopped by hand despite motor rotation. For example, the torsion drive can be provided with a clutch which engages when stopping by hand and let the torsional drive run freewheeling. By a short hand-generated angular momentum in the direction of rotation of the rotational drive is then effective again, so that a motor further rotation of the carousel 12 takes place. In this third embodiment, a safety device is provided which ensures that the carousel can be turned by hand in case of failure of the actuator and / or rotational drive.

Actuator 30 and rotary drive also each have an overload protection device that switches off the respective overload, for example, when a hand or an arm in the space between the rotating carousel 12 and the inside of the side wall 40a, 40b device.
