Description

The present invention relates to a piece of furniture with a furniture part on which a door element is mounted pivotably about an axis of rotation via at least one hinge, the door element being adjustable in height relative to the furniture part in the longitudinal direction of the axis of rotation via an adjusting device.

the DE 10 2004 006 330 A1 discloses a building or furniture fitting with a first fitting part which is rotatably held on a second fitting part. The two fitting parts are adjustable in height, with a threaded spindle on one of the fitting parts being held so that it can rotate but cannot be displaced axially. Only relatively small differences in height can be compensated for by this adjustment device, and in addition, assembly or disassembly of a furniture part or a door element is complex.

It is therefore the object of the present invention to create a piece of furniture in which a furniture part and a door element are arranged both rotatable and adjustable in height by simple means.

This object is achieved with a piece of furniture with the features of claim 1.

In the furniture according to the invention, a furniture part and a door element are pivotably mounted via at least one hinge, and they can also be adjusted in height relative to one another using an adjusting device that has a flexible clamping element that is positioned between a first holder on the door element and a second holder is stretched on the furniture part and is guided over an adjustable deflection element. As a result, the function of the height adjustment can be separated from the function of the hinge, the flexible tensioning element being able to effect a height adjustment by moving the deflecting element. An adjustment can thus be effected with simple means. Furthermore, a lateral actuation of the adjusting device in a position where the furniture part and door element are parallel to one another enables simple assembly

The adjustable deflecting element is preferably guided in a displaceable manner and is continuously adjustable. For this purpose, an actuating element with a thread can be provided for adjusting the deflecting element, so that the position of the deflecting element is changed by turning the actuating element in order to change the vertical distance between the two holders.

The adjusting device can have a fixed or integrally formed channel on the first or the second holder, on which the deflecting element is guided. The channel can be oriented in the longitudinal direction both horizontally and vertically or in another direction. If the alignment is horizontal, the access to the actuating element can be configured easily, wherein a corresponding tool for rotating the actuating element can be inserted horizontally into a tool holder.

The adjusting device can optionally have a guide web on the first or second holder, on which the tensioning element is guided. When the tensioning element moves relative to the guide bar, the tensioning element can thus be bent or deflected, the guide bar acting as a floating bearing for connecting the door element to the furniture part.

The flexible tensioning element is preferably designed as a cable pull, for example as a steel cable, belt or chain, so that the tensioning element can move in different directions. The tensioning element is preferably only subjected to tension, the weight of the door element being held by the tensioning element. The weight of the door element is preferably completely absorbed by the tensioning element, and no further support elements are provided which support the door element.

In a further embodiment, the at least one hinge comprises a pin and a bearing into which the pin is inserted such that it can be displaced in the axial direction. The center axis of the pin defines the axis of rotation of the hinge and at the same time also the axis of rotation between the furniture part and the door element. As a result, the pin can be rotated about the axis of rotation relative to the bearing, but can be displaced in the axial direction by the adjusting device. In this case, the at least one hinge can have a stop which limits a lowering of the door element when the adjustment device is deactivated. If, for example, the tensioning element tears, the stop can limit the lowering of the door element, for example the lowering movement can be designed to be less than 10 mm. As a result, the door element is secured against falling out via the at least one hinge.

For easy assembly, the clamping element can be passed through a recess on the first or second holder at least on one side and be provided with a thickened end section that is fixed to the first or second holder, this area as a fixed bearing for the connection of the door element acts on the furniture part. The other side of the clamping element is as already described, deflected on a guide web and guided or adjusted on the adjusting device in order to then also be fixed on a further thickened end section.

In addition, the first holder can be screwed to the door element and the second holder to the furniture part, so that the adjusting device can be easily installed. In order to prevent unwanted relative lowering or lifting between the furniture part and the door element when the furniture part and the door element pivot around the common axis of rotation, at least one fixed bearing or floating bearing is in vertical alignment with the axis of rotation of the at least one hinge. An arrangement is also possible in which both the fixed bearing and the floating bearing are aligned with the axis of rotation.

By adjusting the adjusting device, the length of the clamping element between the fixed bearing and the floating bearing is either shortened or lengthened, with the deflection of the clamping element on the guide web acting as a floating bearing and the fixing of the end section on the first or second holder as a fixed bearing. In particular, by adjusting the adjusting device, the length of the flexible tensioning element between the end section and the guide web is shortened or lengthened.

The adjustment of the adjustment device is particularly preferably carried out with a tool that is attached to the side of an actuating element of the adjustment device, while the furniture part and the guide element are positioned parallel to one another, so to speak, are stacked to form a package and the furniture is thus on one side facing the operator is open.

The furniture according to the invention is preferably designed as a folding sliding door cabinet comprising a furniture body on which the furniture part is pivotably mounted, in particular as a plate-shaped door, and the door element is held displaceably on the furniture body via a guide device. This allows the furniture part and the door element to be moved like a folding sliding door. Preferably, several hinges are provided between the door element and the furniture part, which are arranged offset in height. The adjusting device is preferably arranged at a distance from the one or more hinges, for example in a central area of the door element in relation to the height.

A piece of furniture 1 includes a furniture body 2 , the two side walls 3 comprises, with one or both of the side walls 3 also a middle partition in a furniture body 2 could be. The two side walls 3 are about a floor 6th and a top panel connected to one another, optionally also with a rear wall. On one of the two side walls 3 is a piece of furniture 4th mounted pivotably in the form of a plate-shaped door. On the furniture part 4th is a door element 5 held pivotable, the door element 5 on that of the furniture part 4th remote side on the furniture body 2 is led. This can be done on one face 7th of the top panel a rail can be provided to the door element 5 slidable on the furniture body 2 to keep. The furniture 1 is designed as a folding sliding door cabinet.

In 2 are the furniture part in a rear view 4th and the door element 5 shown having two hinges 8th are pivotably held together. Furthermore, between the furniture part 4th and the door element 5 an adjustment device 10 provided to the height of the door panel 5 relative to the furniture part 4th to adjust. The furniture part 4th is via the hinge parts shown schematically 9 pivotable on the side wall 3 held. The panel-shaped furniture part 4th and the door element 5 can be made of wood-based panels or other materials.

In 3 is a hinge 8th shown in detail. Every hinge 8th comprises a first holding plate 80 with openings 82 and a second holding plate 81 with openings 82 . On the first holding plate 80 is a sleeve-shaped bearing 84 fixed or integrally formed in which a pin 83 is plugged in. The pencil 83 is on a connector 85 firmly on the holder 81 held, but can alternatively also be held movably with a releasable locking device. As the arrow symbolically shows, the pen is 83 slidable in the vertical direction in the camp 84 held. A central axis of the pen 83 forms an axis of rotation between the furniture part 4th and the door element 5 out.

In 4th is the adjustment device 10 shown in detail. The adjustment device 10 includes a first holder 14th on the door element 5 is fixed, and a second holder 11th that on the furniture part 4th is fixed. For this are in the holder 11th openings 12th and in the holder 14th openings 15th for fasteners such as screws.

The essentially plate-shaped holder 11th includes a bend 20th that have a thickened end portion 18th supported, on which one end of a flexible clamping element 13th is fixed. The clamping element 13th is at the bend 20th through a slot-shaped recess 19th performed, the thickened end portion 18th on the walls of the bend 20th is supported.

At the first holder 14th is a thickened end portion 17th fixed to which the other end of the clamping element 13th is fixed. This definition of the clamping element 13th at the end portion 17th corresponds to a fixed bearing for connecting the door element 5 on the furniture part 4th . There is also an actuator 16 provided to the second holder 11th relative to the first holder 14th adjustable in height.

As in 5 is on the first holder 14th an integrally formed channel 26th which extends essentially horizontally in the assembled position, but can also be oriented in other directions. In the canal 26th is a deflection element 21 slidably guided that a recording 22nd for a mushroom-shaped end section 23 on the actuator 16 having. The actuator 16 is rotatable in the mount 22nd , but axially immovable, held. The actuator 16 includes a threaded portion that is threaded into an internal thread on a web 24 is screwed in. The bridge 24 is at a recess 25th on the canal 26th axially immovable. This allows by turning the actuating element 16 the deflection element 21 along the canal 26th be moved.

At the canal 26th is also a slot-shaped recess 27 formed in which the thickened end portion 17th can be inserted. The thickened end portion 17th includes a gutter 28 in which the walls are adjacent to the slot-shaped recess 27 engage in the assembled position. This allows the thickened end portion 17th for mounting in the slot-shaped recess 27 inserted and guided on it.

The flexible clamping element 13th is on opposite sides at the end sections 17th and 18th fixed. On the holder 14th it is about the deflection element 21 guided in a loop, so that by moving the deflection element 21 the end section 18th closer to the end section 17th moved or the distance increased.

At the first holder 14th is also a guide bar 29 formed on which the flexible clamping element 13th is guided and diverted. This area where the guide or deflection of the clamping element 13th on the guide bar 29 takes place, corresponds to a floating bearing for the connection of the door element 5 on the furniture part 4th . The weight forces are transferred via the tensioning element 13th and the force transfer via the fixed bearing and the floating bearing in the holder 11th and 14th .

The flexible clamping element 13th is designed in the illustrated embodiment as a cable, in particular as a steel cable. It is also possible to use the clamping element 13th to be designed as a belt or chain, whereby a certain flexibility can be used for the adjustment process.

In 6th is the adjustment device 10 shown in an assembled position, with a tool 30th in the form of an Allen key in a tool holder on the actuating element 16 intervenes. The adjustment of the adjustment device 10 takes place here in an advantageous manner when the furniture part 4th and the door element 5 are positioned almost parallel to each other, that is, when the furniture is 1 is in the open state. For this purpose, the tool is laterally aligned horizontally in the gap that is created between the furniture part 4th and the door element 5 brought into engagement with the tool holder. By turning the actuating element 16 can the door element 5 relative to the furniture part 4th can be adjusted in height. The total weight of the door element 5 are taken up by the adjusting device, in particular by the clamping element 13th transfer.

In 7th is the adjustment device 10 shown in a first position. The actuator 16 engages with the thread in the web designed as a projection 24 and holds with its end section 23 the deflection element 21 to which the clamping element 13th is led. The door element 5 hangs on the furniture part 4th by the clamping element 13th with a first end at the thickened end portion 18th on the second holder 11th and with the other end at the end portion 17th on the first holder 14th is set after it is over the guide bar 29 has been guided and diverted. As already described, the connection of the clamping element corresponds 13th at the end portion 18th here a fixed camp and the deflection or guidance of the tensioning element 13th on the guide bar 29 a floating bearing. In this position the door element 5 relative to the furniture part 4th around the axis of rotation of the hinges 8th be pivoted, due to the flexible design of the clamping element 13th the pivoting movement between the guide web 29 and the end section 18th in a slight twist of the clamping element 13th is compensated. About unintentional relative lowering or lifting between furniture parts 4th and door element 5 to prevent when moving furniture part 4th and door element 5 pivot around the common axis of rotation against each other, the connection of the clamping element, acting as a fixed bearing, lies 13th or end section 18th on the holder 11th in vertical alignment with the axis of rotation of the at least one hinge 8th . The technical operating principle also works alternatively in a manner not shown here if, instead of the fixed bearing, the guide or deflection of the clamping element acting as a floating bearing 13th on the guide bar 29 in vertical alignment with the axis of rotation of the at least one hinge 8th located. A solution in which both the fixed bearing and the floating bearing are in vertical alignment with the axis of rotation of the at least one hinge is also conceivable.

The clamping element acting between the fixed bearing and the floating bearing can be clearly seen 13th arranged inclined with respect to the vertically aligned axis of rotation, as this results in the door element 5 a movement towards the furniture part 4th experiences and as a result any tolerances on the hinges 8th can be compensated. This increases the stability of the joints and creates a more even joint pattern. The tensioning element is preferably 13th inclined at an angle of less than 20 ° to the vertical alignment of the axis of rotation.

In 8th is the adjustment device 10 in one opposite the 7th adjusted position shown. By turning the actuating element 16 is the deflection element 21 further into the canal 26th has been pushed in, causing the clamping element 13th along the guide bar 29 was moved. This is the distance between the guide web 29 and the end section 18th , i.e. the distance between the clamping element 13th between the fixed bearing and the floating bearing, has been shortened so that the first holder 14th relative to the second holder 11th was raised. By turning in the opposite direction, the first holder 14th can also be lowered again. By adjusting the adjustment device 10 can thus adjust the length of the clamping element 13th between the fixed bearing and the floating bearing can either be shortened or lengthened, so that the relative height between the furniture part 4th and the door element 5 can change. The adjustment path of the adjustment device can for example be between 5 mm and 50 mm, in particular 5 mm to 10 mm.

In the illustrated embodiment is only on one of the two holders 11th and 14th a deflection element 21 intended. It is of course also possible to increase the adjustment range on both holders 11th and 14th one deflection element each 21 adjustable.
