Description

State of the art

Devices are known for moving a piece of furniture that is received on a furniture body of a piece of furniture. For this purpose, guide means of the device with at least one swivel arm for swiveling the furniture part are provided, with which the furniture part can be moved from a closed position into an open position of the furniture part relative to the furniture body and back when the device is installed.

Such a device has, for example, a base unit with a base plate on which the guide means act in such a way that a pivot axis, about which the at least one pivot arm is pivotable, is transverse to a base plate plane spanned by the base plate. The devices are, for example, furniture fittings such as flap or upper flap fittings. With modern furniture, a particularly space-saving and visually appealing accommodation of the movement device is desired. As a rule, the pivotable furniture part is accommodated on a furniture body via two comparable units of the movement device.

Object and advantages of the invention

The object of the present invention is to improve a device for moving a furniture part movably received on a furniture body with guide means for pivoting the furniture part, in particular with regard to an aesthetically pleasing appearance of the device on the furniture.

This problem is solved by the independent claims.

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

The invention is based on a device for moving a furniture part received 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 part, with which, when the device is mounted, the furniture part moves from a closed position into an open position of the furniture part relative to the Furniture body and back is movable, wherein the device has a base unit with a base plate, on which the guide means act such that a pivot axis, about which the at least one pivot arm is pivotable, is transverse to a base plate plane spanned by the base plate, and wherein a housing element of the base unit is present opposite the base plate.

The device is designed in particular as a swivel fitting for flaps or upper flaps on upper cabinets. The device comprises in particular the body-side base unit, the guide means with a swivel arm arrangement, preferably with an energy store and / or a damping arrangement, and an assembly unit on the flap side. The base unit has an inner area, which results from the distance between the base plate and the housing element that can be placed thereon, such as a housing plate, the base plate and the housing element preferably being aligned parallel to one another.

In the case of larger furniture flaps to be moved, the components of the movement device must be designed to be sufficiently stable. For a high level of ease of use, in particular, a force support with the force storage device for the opening movement or the damping arrangement for the damped closing movement of the furniture part is provided.

The essence is that there is a cover element for covering the outside of the housing element, connection means being designed such that the cover element can be attached and removed from the housing element without tools. The cover element provides a visual or design element which serves the main purpose of determining the external appearance of the device on the piece of furniture. With the connecting means, it is advantageously possible to attach the cover element to the device or the housing element and, if necessary, to remove it again, in a simple manner or with a few movements and without aids such as a tool. The cover element can also be exchanged for another cover element quickly and easily. For example, it is also possible to select a cover element from a plurality of cover elements that differ in appearance but are otherwise identical and to attach them manually to the device or the housing element.

When the device is mounted on the piece of furniture, a surface side of the base unit or the housing element is at least almost completely, preferably completely, covered by the attached cover element. Since the device is regularly used in a material recess of the furniture body such as a recess on the inside of a side wall of the furniture body, the cover element extends in the attached state parallel to the areas that enclose the material recess, for example an inside of the furniture body side wall.

Preferably, the attached cover element is matched to the remaining part of the device or the base unit in such a way that the attached cover element can be sunk flush with the furniture body or the inside of the furniture body side wall.

The cover element corresponds in the outer shape or in the basic shape or in the surface shape to the housing element or the surface side of the base unit, which is formed opposite the base plate. The cover element covers the base unit or the housing element, in particular precisely at the edge.

Preferably, the connection means on the cover element are not visible or not recognizable on the outwardly directed side which points outward in the attached state. In the simple case, the visible outside of the cover element forms a completely closed or flat or contour-free surface.

The cover element is preferably a thin plate-like component with a constant thickness of, for example, 0.5 to 3 millimeters thick. The cover element is preferably made of a metal material or a plastic material or a composite material comprising different materials. The cover element can optionally comprise a design cover layer or a decorative surface.

According to the invention, the housing element and / or the cover element comprise a ferromagnetic material, and the connecting means are designed as magnetic means. This is a connection option that is particularly easy to set up. In particular, it is possible to dispense with a special shape for setting up a latching at the interacting connection points or on the housing element and on the cover element, since the holding force is provided solely by magnetic force. With the magnetic means, for. B. on the Opening on the housing element and the engagement portion on the cover element are dispensed with.

The magnetic means advantageously comprise a permanent magnet. The magnetic force is thus permanently provided. The magnetic means or the permanent magnets are preferably present at several points on the housing element and / or the cover element. In this way, the magnetic force active points and / or the overall holding force for holding the cover element on the housing element can be selected almost arbitrarily or set to a desired minimum value, depending, for example, on the number and / or size of the permanent magnets used and their respective holding forces total holding force of the individual magnets.

A further advantage in connection with magnetic means is that the magnetic means comprise a magnetic film. A magnetic film is available in different forms and has a comparatively low weight, with a two-dimensional arrangement on the cover element and / or the housing element. A magnetic film can also be selected or manufactured in a variable manner in terms of its thickness and its surface shape.

It is preferable if the cover element is formed completely or solely from a magnetic film. This further simplifies the structure, while at the same time it is advantageous because it is simple to attach or connect by magnetic forces on the ferromagnetic housing element.

Finally, there is an advantage that the magnetic means comprise a magnetic film with an optically designed surface. In this way, in addition to the advantageous attachment or connection, the appearance of the cover element and thus of the device on the furniture can be determined according to individual specifications.

The magnetic film preferably has a surface that is optically designed by printing. A magnetic film designed using printing technology opens up a large number of different optical design options for the device.

The invention also extends to a piece of furniture with a furniture body and a movable furniture part received thereon with a device according to one of the designs described above.
The piece of furniture is, for example, a cupboard unit with a furniture flap like a wall unit with a top flap. The device is designed, for example, as a furniture or flap or upper flap fitting.

As a rule, the piece of furniture comprises two swivel or flap fitting units of the same type for providing the same-sided pivoting kinematics of the furniture flap, the two fitting units being effective between the furniture body and the furniture flap. The respective base unit of the two fitting units is attached to the furniture body. The respective assembly unit of the two fitting units is attached to the furniture part or the flap, for example on the inside on a right side edge or on a left side edge of the furniture flap. The swivel arm arrangement acts between the base unit and the mounting unit, with one end engaging the base unit and another end engaging the mounting unit, preferably in an articulated manner. The swivel arm arrangement preferably has a multi-joint with several articulated swivel arms on each fitting unit.

In the following, the same reference numerals are sometimes used for corresponding elements of different exemplary embodiments.

Fig. 1 shows in perspective a piece of furniture according to the invention or an upper cabinet 1 with a box-shaped furniture body 2 and a furniture part received on it, which is designed as a plate-like top flap 3, which is shown in an open position relative to the furniture body 2.

The furniture body 2 comprises two opposite, upright side walls 4 and 5, which are connected at the bottom to a sub-floor 6 and at the top with a top floor 7. The rear of the furniture body 2 is closed by a rear wall 8.

To move the top flap 3 about a horizontal pivot axis relative to the furniture body 2 from the in Fig. 1 In the open position shown in a closed position (not shown) moved towards the furniture body 2 at the front, there is a movement device according to the invention 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 similarly, but for a functionally correct arrangement on the respective side wall 4 or 5 in relation to each other.

Each fitting unit 10 and 11 comprises a base unit 12, guide means 13 with a swivel arm arrangement 14 and a mounting unit 15. The base unit 12 is connected to the mounting unit 15 via several articulated swivel arms of the swivel arm arrangement 14, which is fixed to an inside of the upper flap 3 is sunk in a material recess.

In addition, the guide means 13 have an energy store 21 to support the opening movement of the upper flap 3 in the open position and a damper device 22 for a damped closing movement of the upper flap 3 in the closed position (see Fig. Fig. 4 ). In the relevant Figures 4 , 7th , 11 and 12 the energy storage device 21 has no effect on the swivel arm arrangement 14, since the three helical springs of the energy storage device 21, for example, are not attached to an engagement element which is present on the side of the swivel arm arrangement 14.

The base unit 12 is preferably formed from a sheet metal component and comprises a flat, flat or thin base plate 16 and a flat, thin housing element 17 opposite the base plate 16 (see Fig. Fig. 4 ), for example a housing plate. The housing element 17 is according to Figs. 1 and 2 covered with a cover element 18 or a cover plate.

In addition, an end section 19 is provided on the end face of the base unit 12, the outside of which is oriented transversely to the plane of the base plate 16. The relevant swivel arms of the swivel arm arrangement 14 engage through a rectangular recess 20 in the end section 19. The width of the end section 19 designed as a plug-on component corresponds to a usual width a of the side wall 4 of 16 millimeters. The total width or thickness of the fitting units 10 and 11 is approximately 12 millimeters, so that accordingly the respective material recess in the side walls 4 and 5 is also approximately 12 millimeters deep, which means a residual bottom thickness of the side walls 4, 5 in the area of the respective material recess results in about 4 millimeters.

In Fig. 3 , which represents the fitting unit 10 on the furniture body 2 without the furniture part or without the top flap 3, indicates how the cover element 18 can be manually attached to the base unit 12 (without end section 19) that is completely mounted on the side wall 4. For this purpose, the cover element 18 is moved towards the housing element 17 according to movement arrow P1 in the alignment that is consistent with the housing element 17, with an upper edge of the cover element 18 positioned at the top and a flat inner side 18a of the cover element 18 facing the housing element 17. This takes place in that the cover element 18 is inclined slightly to the vertical or with which the upper edge of the cover element 18 is inclined towards an upper edge of the housing element 17, which Fig. 3 clarified. The upper area of the cover element 18 is then brought into engagement on the housing element 17, the lower area of the cover element 18 being finally pivoted towards the housing element 17 according to the movement arrow P2, pivoted about the previously set up point of engagement of the cover element 18 on the housing element 17. At the end of the pivoting in the direction P2, when the lower area of the cover element 18 comes into contact with the housing element 17, the lower area of the cover element 18 is also brought into engagement on the housing element 17, which occurs with a latching action.

The above-described attachment of the cover element 18 to the housing element 17 takes place with the connection means explained in more detail below.

The connecting means comprise upper latching means 23 and lower latching means 24.

The upper latching means 23 comprise a two-part engagement section 25 on the cover element 18 and an opening 26 on the housing element 17 for setting up a latching of the cover element 18 on the housing element 17. The opening 26 comprises two identical rectangular openings 29, 30. The engagement section 25 comprises a first web section 27 and a second web section 28, the two web sections 27, 28 being present or fastened in the upper edge area on the inside 18a of the cover element 18. The two web sections 27, 28 are offset equally far down from an upper edge of the cover element 18 and are spaced apart from one another in the direction of the edge profile of the upper edge. The web sections 27, 28 are identical and are each formed as sheet metal strips bent twice with an upwardly open L-shaped shoulder on the inside 18a. The web section 27 engages with its L-shaped shoulder through the first rectangular opening 29 in the housing element 17 and the web section 28 engages with its L-shaped shoulder through the second rectangular opening 30 in the housing element 17, which is identical to the rectangular opening 29. The rectangular openings 29 and 30 each provide a rigid opening section with their opening edges, on which the respective web section 27 or 28 engages behind in the locked state. A latching of the cover element 18 at the top of the housing element 17 can thus be set up by the attachment according to P1. The latching enables the above-described pivoting of the cover element 18 according to arrow P2 and pivoting away against P2.

A further latching of the cover element 18 with the lower latching means 24 or at its lower area with an area at the bottom of the housing element 17 is with an engaging section 31 each with a bent web section 32 and 33 on the cover element 18 on the one hand and on the housing element 17 with an opening 34 on the other comprising rectangular openings 35, 36 and one resilient opening section 37, 38 each (see Sect. Fig. 4, 6 ). The resilient opening sections 37, 38 are preferably designed as thin bar springs made of spring steel.

At the end of the pivoting movement of the cover element 18 according to P2, the web sections 32, 33 come into contact with the associated resilient opening section 37, 38. The web section 32 presses with an oblique front flank 32a against the resilient opening portion 37, which due to a pressure applied by a person on the cover element 18 in the direction of the housing element 17 is somewhat elastic, bends transversely to the longitudinal direction of the resilient opening portion 37 until the web portion 32, with a lower edge of the flank 32a , comes past the opening portion 37 and locked behind this. The opening section 37 springs back and comes to rest against a further or rear sloping flank 32b of the web section 32. In the last assembly step, the cover element 18 is pulled almost slightly towards the housing element 17, the flank 32b snapping in behind the bar springs. The resilient opening section 37 or the bar spring presses the web section 32 inward toward the housing element 17.

In a corresponding manner, the web section 33 latches on the rectangular opening 36 with the resilient opening section 38 or the bar spring.

In the locked state of the cover element 18, the inside 18 of the cover element 18 is preferably flat on an outside of the housing element 17.

The latched cover element 18 is removed from the housing element 17 in a corresponding manner, but in the reverse order of the assembly steps described.

The opening sections 37, 38, which extend parallel to the plane of the inside 18 and are designed as bar springs, are supported on both sides of the respective rectangular opening 35, 36 in two bearing lugs with inner bearing lugs 39 and outer bearing lugs 40. The bearing lugs 39, 40 have matching through openings for this purpose. The ends of the bar springs are bent at an angle outside the outer bearing lugs 40, so that the bar springs are secured in the axial direction.

An alternative fitting unit 10 not according to the invention is shown in FIGS Figures 7 to 10 . Here, too, the connecting means are designed as latching means, with an engaging section which protrudes on the inside on a cover element 41 and which comprises four mushroom-shaped, mutually identical latching heads 42-45. The latching heads 42-45 have two latching heads 42 and 43 positioned in the upper region of the cover element 41 and two latching heads 44 and 45 positioned in the lower region of the cover element 41. The two upper latching heads 42, 43 lie somewhat further apart from one another in the direction of the edge profile of the cover element 41 than the two lower latching heads 44, 45.

Correspondingly, a housing element 46 of the fitting unit 10 also has latching means of the connecting means, which comprise openings 47-50 that match the engagement section or the latching heads 42-45. The four openings 47-50, which are material-free in the plate of the housing element 46, are each formed in a transversely aligned keyhole shape. The keyhole shape has a circular area 51 and an elongated hole area 52 which are connected to one another. The openings 47-50 have two upper openings 47, 48 and two lower openings 49, 50, respectively. In the respective interaction of the mutually associated locking heads 42-45 on the one hand with the openings 47-50 on the other hand, the cover element 41 can be easily attached to the housing element 46 attached to the furniture body 2 together with the base unit 12 in a detachable manner and without tools. First, the at least approximately parallel to the aligned cover element 41 is moved with its inside first and in the correct orientation with the upper edge on top according to the arrow P3 so that the four locking heads 42-45 into the circular area of the respective associated opening 47- 50 is immersed until a front head section 53 of the respective catch head 42-45 with a larger diameter than a shaft section 54 of the catch heads 42-45 is present behind the respective circular area 51. Then the flat inside of the cover element 41 rests against the flat outside of the housing element 46. In the next In the assembly step, the cover element is moved in the direction shown by arrow P4 (see Fig. Fig. 7 ) or moved to the end section 19 on the base unit 12. The shaft section 54 of the latching heads 42-45 reaches the associated slot area 52 of the respective opening 47-50. The cylindrical shaft sections 54 have a diameter that is slightly smaller than the width of the elongated hole area 52, so that at the end of the assembly of the cover element 41 the respective shaft section 54 touches the opposite edges of the associated elongated hole area 52 and a rounded end 52a of the elongated hole area 52 comes into plant.

The cover element 41 then completely covers the housing element 46 and a bent edge of the end section 19 present at the front of the base unit 12 on the inside of the side walls 4, 5.

The dismantling of the cover element 41 from the housing element 46 takes place in the reverse order of the assembly steps described, also in a few simple steps.

A fitting unit 10 according to the invention is shown in FIG Fig. 11 visible, wherein the connecting means are designed as magnetic means. A cover element 56 of the fitting unit 10, advantageously formed as a simple rectangular plate, consists at least partially, for example on the inside or preferably completely, of a ferromagnetic material such as, for. B. a sheet material or from a sheet metal plate. A plurality of distributed permanent magnets 57-60, here for example four, are provided on the outside of a housing element 55. Two permanent magnets 57, 58 are advantageously present on the upper edge of the housing element 55 and two permanent magnets 59, 60 are present on the lower edge of the housing element 55. This in Fig. 11 Covering element 56, shown lifted from housing element 55, is releasably fastened to cover element 56 by moving it towards P5.

In principle, permanent magnets can also be present on the inside of the cover element 56 and the housing element consists of a ferromagnetic material or permanent magnets are provided both on the cover element 56 and on the housing element 56.
