State of the art

Devices for moving a furniture part on a furniture body, with guide means having a swivel arm for swiveling the furniture part being present, are known, for example, as so-called flap or top flap fittings. In modern furniture, a particularly space-saving and visually appealing accommodation of the moving device is essential. As a rule, the pivotable furniture part is accommodated on a furniture body via two comparable units of the movement device.

The WO 2007/041736 A1 , EP 2 110 502 A2 and WO 2016/156514 A1 are to be mentioned as state of the art.

Object and advantages of the invention

The object of the present invention is to provide a piece of furniture with a device for moving a furniture flap accommodated in a movable manner on a furniture body with guide means for pivoting the furniture flap improve, especially with regard to a space-saving arrangement of the device on the furniture flap.

Independent claim 1 solves this problem.

The dependent claims relate to advantageous and expedient developments of the invention.

In the case of larger furniture flaps to be moved, the components of the moving device must be designed to be sufficiently stable. A power assist for the opening movement or a damping arrangement for the damped closing movement of the furniture part can be provided for a high level of operating convenience.

The invention extends to a piece of furniture with a furniture body and a movable furniture flap accommodated thereon with a device as described below. The piece of furniture is preferably in the form of a top cabinet with a top flap, the top flap being movably accommodated via two fitting units of the device or pivotable about a horizontal axis. Both fitting units are designed in particular as multi-joint hinges with a number of interacting swivel arms, so that a number of swivel axes are realized on the swivel arm arrangement.

The device is used to move a furniture flap accommodated on a furniture body of a piece of furniture, with guide means of the device being provided with at least one swivel arm for pivoting the furniture flap, with which, when the device is installed, the furniture flap can be moved from a closed position into an open position of the furniture flap relative to the furniture body and back is, wherein the device has a base unit that can be attached to the furniture body and an assembly unit that can be attached to the furniture flap, the base unit and the assembly unit being connected via the guide means, wherein the assembly unit comprises adjustment means with which an adjustment of the relative position between a part of the guide means acting on the assembly unit and the assembly unit can be carried out, the adjustment means being accommodated in an area lower than an upper side of the assembly unit. The mounting unit can thus be designed to save space. Advantageously, no additional installation space is required in an existing depression in the furniture flap that is matched to the assembly unit. The indentation is preferably a material-free area subsequently worked out of the prefabricated furniture flap, in which a predetermined volume of the material of the prefabricated furniture flap is removed, for example, is milled out of a wood material. A residual base thickness is retained on the furniture flap, so that the side of the furniture flap that is opposite the side with the material recess remains unchanged, like a furniture flap outside, and thus remains optically advantageous.

It is advantageous for a high stability of the assembly unit or for mechanical reasons and for reasons of a minimal use of material required for the production of the assembly unit if the assembly unit is designed like a pot, with a base plate such as a flat bottom of the pot and a wall section extending upwards like a pot wall. The assembly unit has, for example, a pot base which is round or oval in its basic shape and which is enclosed over at least significant areas of the edge of the pot base by a pot wall which protrudes at an angle to the pot base. The pot-like assembly unit can thus be inserted into a suitable material recess or indentation. It is mechanically advantageous or stabilizing that the outer sides of the assembly unit or the base plate and the wall section are in planar contact with the walls of the material recess. This means that the material recess is advantageously present in the furniture part in a way that is matched to the outer shape of the assembly unit.

It is therefore advantageous to use the free space above the base plate or the bottom of the pot up to the upper edge of the wall section or the pot wall or the pot volume of the pot-like area for accommodating the adjusting means. The assembly unit is thus designed to be space-saving despite the adjustment means that are present, in particular the assembly unit does not take up more space than a pot-like assembly unit without adjustment means.

Furthermore, it is advantageous that the assembly unit has a base plate with a base plate spanned by the base plate level, wherein in the area of a base plate edge, there is a wall section protruding from the base plate level, with a contact flange aligned at an angle to the wall section extending outwards on the wall section at a distance from the base plate level, so that the contact flange is present above an area which is outside the base plate edge lies.
The base unit with the base plate is thus advantageously inserted into a region of a wall of the furniture carcass that is lower than a flat inner side. The base unit can thus preferably be accommodated completely or flush sunk in the lower-lying area or slightly overhanging an edge of the lower-lying area. With the help of the contact flange, a secure and stable connection of the movement device to the furniture body can advantageously be produced, for example with screw means such as screws that extend through the contact flange and are screwed into the wall of the furniture body.

The lower-lying area is preferably matched to the shape or size of the base unit and a material recess in a side wall of the furniture body. The material recess is recessed towards adjacent sections of the wall of the furniture carcass with a residual floor of reduced thickness. It is preferable for the material recess to extend as far as a narrow front face of the furniture carcass wall.

The contact flange covers the area outside and above the edge of the base plate, with the area adjoining the edge of the base plate.

The depth of the recess in relation to an inner surface side of the body side wall, in which the recess is made, is matched to the height of the base unit or the height of the wall section plus a material thickness of the base plate and the contact flange. When the base unit is made from one piece of sheet metal, the wall section closes preferably with a bend at the edge of the base plate. The contact flange is then preferably also formed via a z. B. right-angled bend on the wall section.

On the base plate there is one or preferably several first bearing points for pivot axes, which belong to a multi-part pivot arm, for example in the manner of a multi-joint hinge.

The device is used to move a flap that is accommodated on the furniture body with the device and can be pivoted about a vertical or a horizontal pivot axis. The pivot axis is provided by the device or the pivot arm or the multiple arms of the pivot arm.

The device is preferably designed as an upper flap furniture fitting, with the movable furniture part in the closed position assuming a position that is moved as far as possible towards a front side of the furniture body. The device is designed to be attached in an upper front edge region of a left and right side wall of the furniture body, below a top panel of the furniture body. Accordingly, the material recess in the two side walls is then present at the top of the front face.

In order to support the opening movement of the flap, the guide means preferably comprise an energy accumulator such as, for example, a number of parallel compression coil springs and a damping arrangement for the damped closing movement of the furniture flap. A touch-latch function is preferably integrated in the device for triggering the device when the furniture flap on the furniture body is closed. This means that by slightly pressing the closed furniture flap in the closing direction, a lock is triggered, so that the furniture flap is then ejected in the opening direction under the effect of the force accumulator.

The base unit is advantageously connected to an assembly unit via a swivel arm of the guide means, the assembly unit being designed for countersunk attachment in the area of a material recess in the furniture part.

This achieves a space-saving arrangement of the device according to the invention compared to a known mounting unit mounted on the inside of the furniture part, as is realized in known devices. The mounting unit preferably has a basic shape that is comparable to the basic shape of the base unit, with a base plate, wall section and contact flange. According to the invention, the assembly unit does not protrude into the interior of the furniture body when the furniture part is closed and therefore does not reduce any space for accommodating objects. In addition, the sunken accommodation is visually more appealing and less conspicuous.

According to an advantageous embodiment of the invention, the adjustment means allow an adjustment in at least one of three mutually perpendicular spatial directions. Preferably, the adjusting means allow an adjustment in one of three mutually perpendicular spatial directions. In this way, the furniture part can be brought exactly aligned relative to the furniture body. Because of the tolerances that always occur on the furniture and/or the movement device, especially in practice, there are different assembly positions of the furniture part in the assembly position set up for the first time, or there are misalignments between the furniture part and the furniture body, which is visually reflected by non-aligned component edges on the furniture part and on the Furniture body stands out or is undesirable. The adjustment for a fine adjustment of the furniture part relative to the furniture body with the adjusting means is preferably stepless, so that a z. B. tenths of a millimeter adjustment is possible. In particular, a visually appealing closing image of the furniture part in the closed position on the furniture body can be achieved with the adjustment means,

It is advantageous that the adjustment means enable depth adjustment means for depth adjustment of a furniture part that is movably received on a furniture body via the device. The furniture part can thus be brought closer to a front face of the furniture body in the closed position, for example, or moved further away from it. In particular, a desired small gap can be specified when the furniture part is closed to the front side of the furniture body, which counteracts the ingress of dust into the interior of the furniture body when the furniture part is closed.

It is also advantageous that the adjustment means have height adjustment means for adjusting the height of a piece of furniture to which the assembly unit can be attached. In this way, for example, in the closed position of the furniture part on the furniture body, a split image can be determined with a respective gap between adjacent furniture parts of the furniture. In particular, uniform gap widths can be realized with a vertical and/or horizontal gap between two or more furniture parts present on the furniture part in the closed position, which is visually appealing.

Furthermore, it is preferred that the adjustment means comprise lateral adjustment means for lateral adjustment of a furniture part to which the assembly unit can be attached. This enables an advantageous gap pattern and a vertical side edge of the furniture part can be aligned or aligned or brought exactly flush with an outside of a side wall of the furniture body if the width of the furniture part corresponds to the width of the furniture body.

According to an advantageous variant of the invention, the adjustment means comprise a screw arrangement. A screw arrangement is suitable for a stepless, possibly self-locking adjustment, can also be used in cramped conditions, can be constructed from standardized components and can be operated easily or manually with screwdriver tools. Advantageously, the adjusting means include an eccentric arrangement. An eccentric arrangement saves space, is self-locking and can be set up with just a few components.

According to an advantageous embodiment, the adjustment means comprise a worm arrangement. A worm arrangement enables a sensitive and finely graduated adjustment. Furthermore, it is advantageous that quick connection means are provided, with which a swivel arm of the guide means can be releasably connected to the mounting unit. This means that the assembly and disassembly of the furniture part can be carried out in a few simple steps and in an uncomplicated manner.

The same reference symbols are sometimes used for corresponding elements of different exemplary embodiments.

1 shows a perspective view of a piece of furniture according to the invention or a wall cabinet 1 with a box-shaped furniture body 2 and a furniture part accommodated thereon, which is designed as a panel-like top flap 3 , which is shown in an open position relative to the furniture body 2 .

The furniture body 2 comprises two opposing upright side walls 4 and 5, which are connected to a bottom panel 6 at the bottom and to a top panel 7 at the top. The furniture body 2 is closed by a rear wall 8 at the rear.

For moving the top flap 3 about a horizontal pivot axis relative to the furniture body 2 from the in 1 shown open position into a closed position moved towards the front of the furniture carcass 2 (see Figures 5, 6 ) A movement device is present, which is designed as an upper flap fitting 9 . The upper flap fitting 9 has a first fitting unit 10 on the side wall 4 and a second fitting unit 11 on the side wall 5, which are constructed in the same way but for the functionally correct arrangement on the respective side wall 4 or 5 in relation to the side.

Each fitting unit 10 and 11 comprises a base unit 12, guide means 13 with a swivel arm arrangement 14 and a mounting plate 15. The base unit 12 is connected to the mounting plate 15 via a plurality of articulated swivel arms 14.1 to 14.9 of the swivel arm arrangement 14, which is fixed to a Inside of the top flap 3 sunk in a material recess 36 is attached.

In addition, the guide means 13 have an energy accumulator 16 adjustable with an adjustment unit 17 to support the opening movement of the upper flap 3 into the open position and a damping device 18 for a damped closing movement of the upper flap 3 into the closed position.

The base unit 12 is preferably formed from a sheet metal component and comprises a flat, flat or thin base plate 19 and a base plate 19 opposite flat thin cover plate 20, which only in the Figures 1 and 2 or in 12 is partially shown.

In addition, on the front side of the base unit 12 there is a front section 21, the outside of which is aligned transversely to the base plate 19 level. The relevant swivel arms of the swivel arm arrangement 14 reach through a rectangular recess 22 in the end section 21.

The base plate with a quadrangular or rectangular base 12 accordingly has four straight base plate edges 23 to 26, wherein in the exemplary embodiment shown on the two adjacent base plate edges 25 and 26 there is a rectangular or strip-shaped wall section 27, 28 standing perpendicular to the plane of the base plate 19. The wall sections 27, 28 are identical in height, which is preferably less than the thickness of the wall element of the piece of furniture or the side wall 4 of the upper cabinet 1 by a predetermined amount, to which the base unit 12 of the fitting unit 10 is attached. If the side wall 4 has a usual thickness a of 16 millimeters (see 2 , 10, 10a ), then the height h of the base unit 12 is preferably 12 millimeters or less, for example. This allows the base unit 12 to be sunk or inserted flush into a prepared material recess 31 (see Fig. 9, 10a ) if the material recess 31 has a depth of 12 millimeters. The residual bottom thickness of the material recess 31 is then accordingly 4 millimeters. The height h of the base unit is made up not only of the height of the wall section 27, 28 but also of the thickness of the base plate 19 and the thickness of the contact flange 29, 30. With an assumed sheet thickness of z. B. one millimeter and a height h of the base unit 12 of 12 millimeters, the height of the wall section 27 or 28 is ten millimeters.

Contact flanges 29, 30 are provided so that the mechanical weakening of the side wall 4, 5 due to the material recess 31 or due to the lack of wall material does not lead to undesirable consequences compared to the side wall without a material recess 31. The fitting unit 10 or the base unit 12 can be firmly attached to the side wall 4 with the contact flanges 29, 30 and fastening means such as screw means 40 engaging or passing through them, in particular fixed in position and without play. The base unit 12 used also contributes to the stabilization of the weakened side wall 4, 5 in the area of the material recess 31. In this case, a surface contact via the surface contact of the outside of the base unit 12 with the wall of the material recess 31 acts advantageously, which has a stabilizing effect. In addition, the attachment or adhesive effect can be improved or increased by adhesives such as an adhesive layer between the base unit 12 and the material recess 31 .

Each wall section 27 and 28 is adjoined by a contact flange angled at right angles to it, i.e. contact flange 29 on wall section 27 and contact flange 30 on wall section 28. Contact flanges 29, 30 are also rectangular or strip-shaped, for example between 5 and 25 millimeters wide, preferably about 15 millimeters wide.

The fastening means such as the screw means 40 engage z. B. through prepared through holes in the contact flanges 29, 30.

If the base unit 12 is to be flush with an inner side 4a of the side wall 4, it is advantageous if the material recess 31 has a central, recessed main pocket 31a, into which the base unit 12 dips, and on the outside there is a narrow edge with only a small depth of the Material recess 31 is present as a secondary pocket 31b (see Figure 10a ), which is matched to the shape and size of the contact flanges 29, 30. The secondary pocket 31b has a depth which corresponds to the thickness of the abutment flanges 29, 30, whereas the depth of the main pocket corresponds to the thickness of the total thickness of the base unit 12, e.g. B. corresponds to 12 millimeters, based z. B. on the inside 4a of the associated side wall 4.

At the front in the area of the base plate edge 23, when the fitting unit 10 is in the assembled state, the rectangular flat end section 21 is sunk flush with a front narrow end face 4b of the side wall 4.

At the top base plate edge 24 is a perpendicular to the plane of the base plate 19 at right angles projecting wall portion 32 is provided, but without a contact flange, since the Base plate edge 24 connects to the top floor 7 on the underside. To fasten the base unit 12 to the top panel 7, a screw 33 engages through an obliquely aligned passage opening in an angle element 34 and through an opening 35 in the wall section 32, so that the screw 33 can be screwed into the top panel 7 at an angle, with the base unit 12 being screwed in at an angle is drawn up and to the side wall 4.

The mounting plate 15 is also advantageously sunk into a corresponding material recess 36 in the top flap 3 , preferably flush with the inside of the top flap 3 .

In an example that does not belong to the invention, the fitting unit 10 or the base unit 12 can also be attached to the furniture carcass 2 without a material recess (see Fig. 12 ). For this purpose, screw means 37 reach through the cover plate 20 and the holes in the contact flanges 29 and 30 and through adapter means (not shown), which can be inserted between the underside of the contact flanges 29, 30 and the inside 4a of the side wall 4, with corresponding openings therein for reaching through the Screwing means 37, which can be screwed into the side wall 4 and extend beyond the adapter means.

13 shows an alternative fitting unit 38 not belonging to the invention, each with two rectangular contact lugs 39 including a screw hole on the two wall sections 27 and 28, with the contact lugs 39 each having a hole through which screw means can pass and with the contact lugs 39 only extending over a comparatively short distance along the wall sections 29, 30 extend.

figure 14 shows the upper section of the upper cabinet 1 with the upper flap 3 open, with the upper flap 3 being shown in partial section and the mounting plate 15 being shown in its entirety. Accordingly, the mounting plate 15 is received in the matching material recess 36 almost completely countersunk. The basic shape of the mounting plate 15 is comparable to the basic shape of the base unit 12 and has a flat surface Base plate 42, a wall section 43 projecting thereupon and a contact flange 44 projecting at an angle outward on wall section 43. An upper side 44a of the mounting plate 15 or the contact flange 44 and a flat, thin, cover-like cover 41 detachably attached to it protrude slightly beyond the inside 3a of the upper flap 3 . The material recess 36 includes a deeper main pocket 36a and a shallower side pocket 36b, in which the contact flange 44 of the mounting plate 15 is accommodated. Adjusting means 45 for adjusting the relative position between the swivel arm arrangement 14 and the mounting plate 15 are accommodated in the recessed area of the mounting plate 15 above the base plate 42 and within the height of the wall section 43 . The swivel arms 14.5, 14.7 and 14.9 extend from the swivel arm arrangement 14 to the area of the mounting plate 15.

The adjustment means 45 comprise depth adjustment means 46 with an adjusting screw 47, lateral adjustment means 48 with an eccentric 49 and height adjustment means 50 with an adjustment worm 51.

With the depth adjustment means 46, the relative position between the swivel arm arrangement 14 and the mounting plate 15 is adjusted in the directions according to the double arrow P1.

The lateral adjustment means 48 are used to adjust the relative position between the swivel arm arrangement 14 and the mounting plate 15 in the directions according to the double arrow P2.

With the height adjustment means 50, the relative position between the swivel arm arrangement 14 and the mounting plate 15 is adjusted in the directions according to the double arrow P3.

The assembly for releasably attaching the top flap 3 with the mounting plate 15 at the front end of the swing arm assembly 14 is in the Figures 16 and 17 clarified. For this purpose, quick-connecting means 52 are provided which, on the pivot arm assembly 14, have a pivotable latching lever 53 and a pin 54 close to the latching lever 53 and another to the Locking lever 53 spaced pin 55 includes, wherein the longitudinal axes of the pins 54, 55 parallel to the pivot axis of the locking lever 53.

On the mounting plate 15, the quick-connection means 52 comprise a latching lug 56 and a latching hook 57, which are designed to fit the latching lever 53, the pin 54 and the pin 55.

After the upper flap 3 with the mounting plate 15 has been moved to the swivel arm arrangement 14 in the correct position, with the locking lever 53 pivoted counterclockwise, the pin 54 comes into a stop position in a notch of the locking hook 57 and at the same time the pin 55 comes into a notch in the locking hook 57 (see Fig . 17 ). Then the locking lever 53 is pivoted manually in a clockwise direction according to P4, so that a lug of the locking lever 53 engages in a recess of the locking lug 56 and the fixed anchorage is set up.

The disassembly is carried out by the reverse order of the steps that are necessary for assembly.
