Description

[0001] The present invention relates to a furniture corner piece having at least one storage layer.

[0002] These furniture corner pieces can be placed in the corner of a room as furniture such as a bracket, or placed in the corner area of ​​the main body of furniture as a component of furniture. They can also be moved from the initial position to the open or usable position through a combination of rotation and translation.

[0003] Typically, in such furniture corner fittings, the at least one storage layer is concealed by the sidewall of the furniture corner fitting in its initial position, so that objects stored in the furniture corner fitting are hidden from view and / or protected from dust in their initial position, and are easily accessible after translational rotational movement. Rotary fittings are used for translational rotational movement; these fittings are connected to the bottom plate and / or top plate of the furniture corner fitting and have two bearing surfaces that are relatively movable by rolling elements guided in running grooves.

[0004] The purpose of this invention is to provide a furniture corner piece with enhanced stability, which can move precisely from an initial position to an opening position.

[0005] This objective is achieved by a furniture corner piece having the features of claim 1.

[0006] The furniture corner piece according to the invention comprises a cuboid frame having a rectangular, in particular square, base area, having at least one bottom opening and a top opening parallel to the bottom opening, and at least two side openings.

[0007] The bottom plate is received in the bottom opening. The top plate is received in the top opening. At least one side opening receives a side plate that at least partially closes the side opening.

[0008] The furniture corner fitting also includes at least one rotating fitting disposed on the underside of the bottom plate opposite to the top plate and / or on the upper side of the top plate opposite to the bottom plate. The rotating fitting includes two bearing surfaces facing each other and each having at least one running groove therein for guiding rolling elements.

[0009] The shape of the running groove allows the first bearing surface to be movable relative to the second bearing surface, moving from an initial position to an intermediate position, then to an opening position, and finally back to the initial position via a combined translational-rotational motion. The translational portion of the motion is oriented at 45° to one of the side edges of the frame base area.

[0010] The center point of the furniture corner piece contains the same spatial coordinates in both the initial and starting positions.

[0011] The characteristic of this furniture corner fitting is its special stability due to the cuboid frame, which ensures that the two bearing surfaces of the rotating fitting remain parallel to each other during translation-rotation. During translation-rotation, the area of ​​one of the bearing surfaces that is not supported below will not bend due to gravity.

[0012] Advantageous embodiments of the present invention are the subject of the dependent claims.

[0013] According to an advantageous embodiment, the first bearing surface of the rotating fitting is formed on the base plate / top plate.

[0014] According to an alternative embodiment, the first bearing surface of the rotating fitting is connected to the base / top plate. This variation also ensures easy modification of furniture corner pieces using this rotating fitting.

[0015] According to another preferred embodiment, the side panel is designed as a fixing plate for connecting the decorative panel.

[0016] This allows for easy replacement of the decorative panel, and thus allows for simple furniture corner design to adapt to its environment.

[0017] According to a preferred embodiment, the decorative side of the decorative panel is fixed in the side opening and is flush with the outer surface of the frame portion forming the side opening.

[0018] In this embodiment, the shape of the running slot is preferably such that the base region of the frame at the initial position is congruent to the base region of the frame at the opening position.

[0019] According to an alternative embodiment, the decorative panel is attached to the side panel at the front of the frame.

[0020] Here, the shape of the running groove is preferably such that the base region of the frame at the beginning position is positioned relative to the base region of the frame at the initial position by offsetting the material thickness of the decorative panel by a factor of 1 / 3.

[0021] This allows furniture corner pieces to be precisely installed in the same base area at both the initial and starting positions.

[0022] According to a further preferred variation, the decorative panel is fixed to the side panel by means of at least one adjusting unit so that it is aligned with it.

[0023] This makes it easy for the edges of the decorative panels, especially those installed in furniture corner pieces, to match the edges of the surrounding furniture.

[0024] In a further preferred embodiment, decorative panels are arranged at two adjacent side openings, and the edge areas of the decorative panels that are close to each other are rounded to form a common arc cross section.

[0025] According to a preferred embodiment, the rotational portion of the movement between the initial position and the starting position is 90° or 180°.

[0026] According to a further preferred embodiment, the frame has four side openings, wherein a plate that at least partially closes the side openings is inserted into two adjacent side openings.

[0027] The frame itself is preferably composed of multiple hollow profile components.

[0028] Alternatively, the frame can be designed as a single component.

[0029] According to an advantageous further variation, at least a portion of the frame profiles or partial segments of the frame are formed as closed polygons in cross-section, with their legs arranged at right angles to each other, and at least one fixed web extending from its outer surface.

[0030] The closed polygon stabilizes the furniture corner structure, and the at least one fixed web can hold the bracket, etc., in a simple manner.

[0031] The furniture according to the invention has a body having a plurality of side walls and a top plate, characterized in that at least one furniture corner piece as described above is received in the front area of ​​the furniture.

[0047] Figures 16a and 16b are isometric views of alternative embodiments of furniture according to the invention, corresponding to Figures 1 and 4, respectively, and each has rounded furniture corner pieces.

[0048] In the following description of the accompanying drawings, terms such as top, bottom, left, right, front, and back refer specifically to exemplary representations and positions of furniture corner pieces, furniture, frames, side panels, decorative panels, etc., selected in the respective drawings. These terms should not be interpreted restrictively, meaning that different working positions or mirror-symmetric designs may change their meanings.

[0049] In Figures 1 to 4, reference numeral 2 indicates an embodiment of furniture corner brackets. These furniture corner brackets 2 are respectively installed in the corresponding front area of ​​the furniture 100.

[0050] Here, the total height of one of the furniture corner pieces 2 can correspond to the height of furniture 100 minus the height of furniture leg 102, with the main body of furniture 100 supported on furniture leg 102.

[0051] Furniture corner piece 2 can be translated and rotated within furniture 100, while the other front panels 103, 104, and 105 shown here are held on the furniture body as drawer front panels or are pivotable via lateral hinges.

[0052] The top of furniture 100 is covered by cover plate 101.

[0053] Furniture corner pieces 2 are installed in furniture 100 such that they can be moved from the initial position shown in FIG1 along the direction of R1 or R2 to the starting position shown in FIG4 by a combination of translational-rotational movements, wherein the space occupied by furniture corner pieces 2 in furniture 100 is the same as that in the initial position shown in FIG1.

[0054] The middle position of the furniture corner piece 2 with a rotation angle of 60° is shown in Figures 2a and 2b, and the position covering the rotation angle of 120° is shown in Figures 3a and 3b.

[0055] An exploded view of a preferred embodiment of this furniture corner piece 2 is shown in Figure 5.

[0056] The furniture corner piece 2 includes a cuboid frame 3 with a square base area having at least one bottom opening 31 and a top opening 32 parallel to the bottom opening 31, as well as four side openings 33.

[0057] Alternatively, the base area can be designed as a non-square rectangle, wherein the ratio of the side lengths that are perpendicular to each other and form the base area is preferably between 1:1 and 1:1.2.

[0058] As shown in Figures 5 and 6, the bottom plate 6 is received in the bottom opening 31. Correspondingly, the top plate 8 is received in the top opening 32. The two side openings 33 respectively receive the side plates 4 that close the side openings 33.

[0059] It is also conceivable to design the dimensions of the side panel 4 in such a way that it only closes a portion of the side opening 33, so that a portion of the furniture corner piece 2 is accessible in the initial position shown in Figures 1a and 1b, regardless of its positioning.

[0060] In the preferred embodiment shown here, the side panels 4 are sized such that the side openings 33 are completely closed by them.

[0061] In addition, one rotating accessory 7 is located on the underside of the bottom plate 6 away from the corner of the top plate 8, while another rotating accessory 7 is located on the upper side of the top plate 8 away from the bottom plate 6.

[0062] It is conceivable that these rotating components 7 are arranged only on the base plate 6 or only on the top plate 8.

[0063] Here, the rotating component 7 includes two opposing bearing surfaces 71, 72, each having at least one running groove therein for guiding the rolling element.

[0064] The shape of the running groove allows the first bearing surface 71 to move relative to the second bearing surface 72, moving from the initial position shown in Figures 1a and 1b to the starting position shown in Figures 4a and 4b in a combined translational-rotational motion, and then returning to the initial position.

[0065] The translational portion of the movement is therefore at a 45° angle to one of the sides of the base region of frame 3.

[0066] The center point of the furniture corner piece 2 contains the same spatial coordinates in both the initial and opening positions. That is, through a combination of translational and rotational movements, the furniture corner piece 2 can be moved from the initial position shown in Figures 1a and 1b, where the furniture corner piece 2 is flush with the externally enclosed front and side surfaces of the furniture and the front panel 103 and its associated side panels, to the equally flush opening position, where, in the position shown in Figures 4a and 4b, the vertical support formed as the hollow profile 34 is flush with the corner of the furniture 100.

[0067] In each furniture corner piece 2, one or more brackets 9 are preferably defined within the frame 3 to provide one or more storage layers for the furniture corner piece 2.

[0068] Alternatively, the first bearing surface 71 of the rotating fitting 7 can be formed directly on the base plate 6 or the top plate 8, replacing the modified furniture corner piece 2 shown in Figure 5.

[0069] In the preferred embodiment shown here, the first bearing surface 71 of the rotating fitting 7 is connected to the base plate 6 or the top plate 8.

[0070] The top plate 8 and the bottom plate 6 cover the interior of the furniture corner piece 2, and the rotating fittings 7 are arranged below and above them respectively.

[0071] As further shown in Figures 5 and 6, the side panel 4 is formed as a fixed panel, to which the decorative panel 5 is attached, forming a visible surface at the initial position of the furniture corner piece 2, as shown in Figures 1a and 1b.

[0072] With the side opening 33 positioned on the decorative side of the decorative panel 5 and flush with the outer surface of the frame 3 portion forming the side opening 33, the running groove is formed such that the base area of ​​the frame 3 in the initial position is equal to the base area of ​​the frame 3 in the opening position.

[0073] In this variant (not shown here), the hollow profile 34 correspondingly forms the outer edges on both sides of the furniture corner piece 2.

[0074] In this embodiment of the furniture corner piece 2 shown here, the decorative panel 5 is attached to the side panel 4 in front of the frame 3.

[0075] Accordingly, the side plate 4 is fixed inside the frame 3 in the side opening 33.

[0076] Accordingly, in this embodiment, the running groove is formed such that the base region of the frame 3 at the beginning position is positioned relative to the base region of the frame 3 at the initial position by offsetting the material thickness of the decorative panel 5 by a factor of 5.

[0077] This ensures that when the furniture corner piece 2 is rotated to the starting position shown in Figures 4a and 4b, the decorative panel 5 will not come into contact with the furniture body of the furniture 100.

[0078] In order to precisely align the decorative panels 5 within the furniture 100 shown in Figures 1 to 4, each decorative panel 5 is fixed in a manner that is alignable relative to the side panel 4 with the aid of at least one adjusting unit 11.

[0079] This adjustment is shown in Figures 6, 7, 10a-d, and 11a-c. This adjustment unit 11 is essentially cylindrical and is inserted into the corresponding adjustment unit receiving seat 41 of the side plate 4, as shown in Figure 6. Depending on other principles, the adjustment unit may also have other geometries and functions.

[0080] Preferably, two such adjustment units 11 are housed in corresponding adjustment unit receiving seats 41 on each side plate 4.

[0081] On the rear side of the decorative panel 5 facing the side panel 4, as shown in Figures 9 and 10a-d, holes 51 are provided, in which fixing elements, preferably in the form of screws 10, are inserted.

[0082] The head of the screw 10 is hooked into the hook receiver of the adjustment unit 11. Subsequently, by adjusting the hook element within the adjustment unit 11, both vertical adjustment (as shown in Figures 10a-10d) and lateral adjustment (as shown in Figures 11a-11c) can be performed. The adjustment principle illustrated is well known in the prior art.

[0083] When the decorative panel 5 is correctly aligned, the fixing screw 12 can be screwed into the corresponding hole 42 in the side panel 4, and screwed into the corresponding hole 52 in the decorative panel 5 from the side of the side panel 4 away from the decorative panel 5, thereby clamping and fixing it in the current position.

[0084] Figure 8 shows a screw 10 protruding from the rear side of the decorative panel 5 facing the side panel 4.

[0085] The frame 3 of the furniture corner piece 2 can be designed as an integrated frame.

[0086] In the preferred embodiment shown here, the frame 3 is composed of a plurality of hollow profiles 34.

[0087] Preferably, at least a portion of the hollow profile 34 or partial segments of the integral frame 3 have cross-sections forming closed polygons 35, with their legs arranged at right angles to each other, and at least one fixed web 36 extending from its outer surface. Due to the special arrangement of the fixed web 36, some hollow profiles 34 also have additional grooves 37.

[0088] Some preferred embodiments of the cross-sectional design of this hollow profile 34 are shown in Figure 12.

[0089] The fixed web 36 is preferably used to hold the bracket 9 or connect decorative elements.

[0090] The hollow profiles 34 are interconnected by corner connectors 38.

[0091] An exemplary corner connector 38 is shown in Figures 14a and 14b. Each corner connector 38 has a corner block 381, and arms 382 protrude from the corner block 381 at right angles to each other, which can be inserted into the end receiver of the hollow profile 34.

[0092] The corner connector 38 preferably still has a corresponding hole 383 in the arm 382.

[0093] Accordingly, mounting holes 341 are provided in the end region of the hollow profile 34, through which the hollow profile 34 can be additionally fixed to the corner connector 38 by means of screws, plugs, bolts or other fasteners.

[0094] As further shown in Figure 13, in a preferred embodiment, the hollow profile 34 additionally has a fixing hole 342 for receiving the bracket holder 13, as shown in the example in Figure 5.

[0095] Figures 15a, 15b and 16a, 16b show another embodiment of the furniture corner piece 2 installed in furniture 100.

[0096] In this embodiment, the decorative panel 5' is rounded at the opposing vertical side areas and together forms an arc cross section, which is flush with the rounded edge of the front panel 103' of the furniture corner piece 2 and the rounded edge of the cover plate 101', forming the left side of the furniture 100 in Figures 15 and 16.

[0097] Although in the illustrated embodiment, the furniture corner piece 2 reaches the starting position after rotating 180°, alternative embodiments, not shown here, are also conceivable where the starting position is reached by rotating 90°.
