CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of European patent application no. EP 25164343.3, filed Mar. 18, 2025, and European patent application no. EP 25173430.7, filed Apr. 29, 2025, the contents of which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] The present invention relates to a frame in modular design for installation in a piece of furniture, in particular for a corner cabinet. The frame can comprise a pull-out device for a corner cabinet. Pull-out devices for corner cabinets are used to make the storage space in the corner of a corner cabinet more accessible.DESCRIPTION OF RELATED ART

[0003] Document EP 1615529 B1 shows a corner cabinet with a built-in unit E2 located in the corner area and a built-in unit E1 arranged inside the cabinet door for storing goods to be stored in the corner cabinet. When the cabinet door is opened, the built-in unit E1 moves with the cabinet door, pivoting around the vertical edge of the cabinet and moving away from the edge of the cabinet. The built-in unit E2 is connected to the built-in unit E1 via a sliding and swivel guide, so that during the swivel movement in the corner cabinet, it is moved from the corner position to the original position of the built-in unit E1. The built-in unit E1 comprises a side frame that is guided by a roller in a guide rail attached to the side wall of the cabinet. In addition, the side frame is connected to a front frame that supports the cabinet door. The guide rail is part of a swivel frame attached to the side wall, which comprises a vertical retaining plate and an angle bracket running along the bottom of the cabinet. In the corner area of the cabinet, there are support plates that support two horizontal guide rails running along the rear wall for the built-in unit E2. If this swivel frame is prefabricated, a different swivel frame must be provided for a cabinet door located on the right-hand side than for a cabinet door located on the left-hand side. The swivel frame used for a cabinet door located on the right-hand side according to this previously known solution can therefore not be used if the cabinet door is to be located on the left-hand side of the cabinet.

[0004] If the swivel frame is to be prefabricated as a module, its dimensions make it bulky and therefore require a lot of transport space. Therefore, the swivel frame is not suitable for transport in assembled condition and is advantageously disassembled into its individual parts in a space-saving manner for transport purposes. If installation in the cabinet is to be carried out in a carpentry workshop or at a furniture manufacturer, the assembly of this swivel frame therefore requires a corresponding amount of time.

[0005] Document WO2008 / 116577 A1 describes a pull-out fitting for a cabinet with a body that has a short side wall and a long side wall. Two guide rails for a slide holder are arranged on the inside of the short side wall. In addition, the slide holder can be swiveled around the front edge of the short side wall by means of a swivel device. The swivel device is formed by a pin that slides in a guide track located on the inside of the short side wall. When the pin is in a position close to the front edge of the short side wall, the object carrier connected to the pin can be swiveled around a vertical swivel axis running through the pin. However, according to the design shown in this document, it is not possible for a second slide to be present, as there is no space provided for a second slide.

[0006] Document WO 2020 / 225790 A1 shows a pull-out device with a swivel device for a first slide, which is coupled to a swivel device for a second slide. The two swivel devices are coupled to each other in such a way that when the first object carrier is pulled out and then swiveled, the second object carrier is rotated about a second swivel axis. The second swivel device can be mounted inside the cabinet body on either the right or left side. However, the swivel devices must be installed individually by the furniture manufacturer according to the desired right-hand or left-hand position. In addition, at least the swivel axis for the second swivel device must be installed in the cabinet floor and on the cabinet ceiling, so that in particular the floor space is not free of fixtures.

[0007] The same limitation appears to apply to the solution described in document KR 1999 022088 U. In that document, the first and second object carriers are guided in guide rails attached to the rear wall and side wall of the cabinet, respectively. However, the coupling mechanism that enables the second object carrier to move in a translational motion when the first object carrier is swiveled requires a swivel bearing attached to the cabinet floor. Therefore, this solution also requires modifications to be made to the cabinet floor.

[0008] The proposed solutions, insofar as they contain first and second swiveling or sliding object carriers, therefore have the disadvantage that installation is complex and can only be carried out by the furniture manufacturer. Prefabricated modules cannot be used. In addition, the known solutions have the disadvantage that installations must be made on the cabinet floor, which makes access to the cabinet floor difficult, for example for cleaning the cabinet floor.

[0009] Therefore, it is an object of the invention is to develop a frame in modular design for a pull-out device that can be used for both left-hand and right-hand installation. A further object of the invention is to develop a frame in modular design for a pull-out device that can be installed in the cabinet in just a few steps. Another object of the invention is to keep the cabinet floor as free of fixtures as possible so that it can be easily cleaned.SUMMARY OF THE INVENTION

[0102] In particular, the first support element end section 33 of the first support element 17 and the first connecting element end region 19 of the first support connecting element 18 are connected, and the first support element end section 41 of the second support element 27 and the second connecting element end region 29 of the first support connecting element 18 are connected. According to the embodiment shown in FIGS. 5a and 5b, a second support connecting element 28 is shown. The second support connecting element 28 has a first connecting element end region 49 and a second connecting element end region 59. According to the present embodiment, the second support element end section 34 of the first support element 17 and the first connecting element end region 49 of the second support connecting element 28 are connected, and the second support element end section 42 of the second support element 27 and the second connecting element end region 59 of the second support connecting element 28 are connected.

[0103] According to the present embodiment, the first support connecting element 18 contains a guide device 60, which is visible in FIG. 2c, FIG. 5a, or FIG. 5b. The guide device 60 contains a guide element which is configured as a guide rail. The first support element 17, the second support element 27, the first support connecting element 18 and, if applicable, the second support connecting element 28 can be moved in the guide device 60 between a retracted state and an extended state. The first support element 17, the second support element 27, and the first support connecting element 18, optionally the second support connecting element 28, and the guide device 60 are pivotable about a vertical pivot axis in the extended state, as shown in FIG. 2c, FIG. 5a, or FIG. 5b.

[0104] According to the present embodiment, the pull-out device 35 contains a strut 53 which contains at least one rotary means 54 which is configured to be received in the second frame module 40 of the frame 10. The pull-out device 35 with the strut 53 can be pivoted about a vertical pivot axis. The pivot axis runs through the rotary means 54, 57.

[0105] The first support element 17 has a handle element 55 on its second support element end section 34. The handle element can be used to manually move the first mounting frame 51 of the pull-out device 35.

[0106] A coupling arrangement 36 can be activated by moving the first mounting frame 51. The second installation unit 30 can be moved via the coupling arrangement 36 when the first mounting frame 51 is moved, when the handle element 55 is actuated by a user to move the pull-out device 35. According to the present embodiment, the coupling arrangement 36 comprises a first arm element 37, a second arm element 38, a third arm element 39, and a coupling element 48 connected to the frame 10. The first arm element 37 is pivotally connected at a first end to the second mounting frame 52 carrying the second installation unit 30 and at a second end to a first end of the second arm element 38. In addition, the first arm element 37 and the second arm element 38 are also connected to the coupling element 48.

[0107] The second arm element 38 is connected at a second end to a first end of the third arm element 39. The third arm element 39 is connected at a second end to the pull-out device 35. The second end of the third arm element 39 is thus moved along with the first mounting frame 51 when the pull-out device 35 is actuated.

[0108] Door 9 of corner cabinet 100 is opened at the start of operation of the pull-out device 35 or to remove loads stacked in the first installation unit 20. An operation of the pull-out device 35 is not absolutely necessary for removing or storing loads in the first installation unit 20.

[0109] FIG. 2b shows the corner cabinet 100 according to FIG. 2a in the pull-out phase of the pull-out device 35. The pull-out device 35 is guided by means of the first guide element 56 in the first guide recess 45 of the first connecting element arm 43 of the second connecting element 4 of the frame 10. The first guide recess 45 has a straight part and a curved part. The straight part runs essentially parallel to the right side wall 5. In FIG. 2b, it is not visible that the pull-out device 35 is guided by means of the second guide element 66 in the second guide recess 46 of the second connecting element arm 44 of the second connecting element 4 of the frame 10, see FIG. 5a or FIG. 5b. The second guide recess 46 has a straight part and a curved part. The straight part runs essentially parallel to the right side wall 5. In particular, the first guide recess 45 and the second guide recess 46 have the same course.

[0110] The pull-out device 35 is used to pull the first installation unit 20 out of the interior of the corner cabinet 100 by using the handle element 55. At the same time, the coupling arrangement 36 causes the second mounting frame 52, which carries the second installation unit 30, to move along the guide rail 1 from the left side wall 6 towards the right side wall 5. The second mounting frame 52 can be guided, for example, via roller elements in at least one of the first or second guide rails 1, 2.

[0111] At the end of the pull-out phase of the pull-out device 35, the first installation unit 20 is moved past the second installation unit 30. The curved part of the first guide recess 45 of the first connecting element arm 43 can assist in this by pivoting the part of the first installation unit 20 facing the rear wall away from the second installation unit 30 following behind. The curved part of the second guide recess 46 of the second connecting element arm 44, which is not shown, has the same effect.

[0112] FIG. 2c shows the corner cabinet 100 according to FIG. 2a during the pivot movement of the pull-out device 35 around the end point of the curved part of the first guide recess 45. In the view according to FIG. 2c, the first installation unit 20 is rotated counterclockwise about a pivot axis extending at right angles to the drawing plane. The first installation unit 20 is moved away from the door opening by the rotary movement. The coupling arrangement 36 simultaneously causes a further displacement of the second installation unit 30. The third arm element 39 of the coupling arrangement 36 is moved together with the first mounting frame 51, thereby exerting a tensile force on the second arm element 38. The end of the second arm element 38, which is connected to the ends of the first arm element 37 and the end of the coupling element 48, causes a further displacement of the second mounting frame 52. The coupling element 48 performs a counterclockwise rotational movement about the end of the coupling element 48 that is rotatably attached to the second connecting element arm 44 (shown in FIG. 5b). The opening angle between the coupling element 48 and the first arm element 37 decreases as the pull-out device 35 continues to rotate.

[0113] FIG. 2d shows the corner cabinet according to FIG. 2a in the final phase of the pivot movement of the pull-out device 35. The second installation unit 30 is fully accessible because it has been moved by means of the coupling arrangement 36 essentially to the position of the first installation unit 20, i.e., into the area of the open door 9. In FIG. 2d, the second connecting element 4 is shown partially cut away. The first connecting element arm 43 is partially cut away so that the second connecting element arm 44 lying underneath is partially visible. The coupling element 48 is connected at one of its ends to the second connecting element arm 44, see also FIG. 5a or FIG. 5b.

[0114] FIG. 3 shows a view of a frame 10 in modular design for installation in a piece of furniture according to a second embodiment. The frame comprises a first guide rail 1, a second guide rail 2, a first connecting element 3, and a second connecting element 4. The first frame module 15 is formed by the first guide rail 1, the second guide rail 2, the first connecting element 3, and the second connecting element 4.

[0115] The first connecting element 3 has a first connecting element end 31 and a second connecting element end 32. The second connecting element 4 has a first connecting element end 71 and a second connecting element end 72.

[0116] The first connecting element end 31 is connected to the first guide rail end 11 of the first guide rail 1, and the second connecting element end 32 of the first connecting element 3 is connected to the first guide rail end 21 of the second guide rail 2. The first connecting element end 71 is connected to the second guide rail end 12 of the first guide rail 1, and the second connecting element end 72 of the second connecting element 4 is connected to the second guide rail end 22 of the second guide rail 2. A second frame module 40 can be connected to the first frame module 15 by means of a suspension device 25, wherein the suspension device 25 is configured to couple the second frame module 40 into one of the first or second connecting elements 3, 4.

[0117] According to the present embodiment, the second frame module 40 has a first connecting element arm 43 and a second connecting element arm 44. In particular, the second guide rail end 12 of the first guide rail 1 and the second guide rail end 22 of the second guide rail 2 are connected to the second connecting element 4. The first connecting element arm 43 and the second connecting element arm 44 of the second frame module 40 each contain a first suspension element 16 and a second suspension element 26, respectively, of a suspension device 25, which can be connected to the second connecting element 4.

[0118] The first connecting element arm 43 and the second connecting element arm 44 can be connected to each other via at least one support element 47. The first connecting element arm 43 and the second connecting element arm 44 can each contain the first guide recess 45 and the second guide recess 46, respectively.

[0119] At least one of the first and second guide rails 1, 2 can be configured to accommodate a second installation unit 30, which can be moved along the first and second guide rails 1, 2 by means of roller elements arranged in at least one of the first or second guide rails 1, 2, see in particular FIGS. 2a to 2d. In particular, at least one of the first and second guide rails 1, 2 can be configured as a U-shaped or L-shaped profile element. FIG. 3 shows a second mounting frame 52, which enables the installation unit 30 to be moved along the first and second guide rails 1, 2. Via a coupling arrangement 36, the second mounting frame 52 and thus the second installation unit 30 can be moved when the first mounting frame 51 is moved, for example when a pull-out device 35 is actuated by a user by means of a handle element (not shown).

[0120] According to the present embodiment, the coupling arrangement 36 comprises a first arm element 37, a second arm element 38, a third arm element 39, and a coupling element 48 connected to the second frame module 40. The third arm element 39 is connected to the first mounting frame 51. The connection between the second arm element 38 and the third arm element 39 is analogous to the embodiment shown in FIG. 5a or FIG. 5b. The first arm element 37 is rotatably connected at a first end to the second mounting frame 52 of the second installation unit 30 and at a second end to a first end of the second arm element 38. In addition, the first arm element 37 and the second arm element 38 are also connected to the coupling element 48.

[0121] The second arm element 38 is connected at a second end to a first end of the third arm element 39 when installed, which is not shown in FIG. 3. The third arm element 39 is connected at a second end to the first mounting frame 51 of the pull-out device 35. The second end of the third arm element 39 is thus moved along with the first mounting frame 51 when the pull-out device 35 is actuated.

[0122] The first guide recess 45 and the second guide recess 46 can each, for example, be configured as a slot. A guide pin can be guided in the slot. The guide pin can be part of a first installation unit 20, see in particular FIGS. 2a to 2d or FIGS. 5a, 5b or FIGS. 6a, 6b. According to the present embodiment, the first guide recess 45 and the second guide recess 46 may each comprise a straight part and a curved part. According to the present embodiment, the curved part of each guide recess has an S-shape.

[0123] FIG. 4 shows a view of a frame according to the second embodiment in the assembled state. In the assembled state, the suspension device 25 in this embodiment surrounds the second connecting element 4. The suspension device 25 contains a first suspension element 16 and a second suspension element 26. The first suspension element 16 and the second suspension element 26 are arranged in corresponding end sections of the first connecting element arm 43 and the second connecting element arm 44 of the second frame module 40, respectively.

[0124] FIG. 5a and FIG. 5b each show a perspective view of a first frame module 15 and a second frame module 40 of a frame 10 for a corner cabinet and a pull-out device 35 according to the third embodiment. The first frame module 15 comprises a first guide rail 1, a second guide rail 2, a first connecting element 3, and a second connecting element 4. The first guide rail 1 has a first guide rail end 11 and a second guide rail end 12. The second guide rail 2 has a first guide rail end 21 and a second guide rail end 22. According to this embodiment, the second connecting element can comprise an end region at the second guide rail end 12 or at the second guide rail end 22. According to this embodiment, the second guide rail end 12 of the first guide rail 1 and the second guide rail end 22 of the second guide rail 2 are not connected to each other.

[0125] The pull-out device 35 according to the third embodiment for the installation unit 20 contains a first support element 17, a second support element 27, and a first support connecting element 18 and a second support connecting element 28, which form a mounting frame 50, for example a first mounting frame 51 according to FIGS. 2a to 2d. The first support connecting element 18 has a first connecting element end region 19 and a second connecting element end region 29. The first support connecting element 18 is connected to the first support element 17 in the first connecting element end region 19, and the first support connecting element 18 is connected to the second support element 27 in the second connecting element end region 29. The first support element 17 has a first support element end section 33 and a second support element end section 34. The second support element 27 has a first support element end section 41 and a second support element end section 42. The pull-out device 35 contains the first guide element 56 shown schematically in FIG. 2a to FIG. 2d, which, according to this embodiment, contains a first guide element 65 and a second guide element 66. The second guide element 66 contains a first engagement element 61, which is configured to engage in the first guide recess 45 of the first connecting element arm 43 of the second frame module 40 of the frame 10. The engagement element 61 can, for example, be configured as a pin element, which can slide in the guide track configured as a slot. In this embodiment, the guide track corresponds to the first guide recess 45 of the first connecting element arm 43.

[0126] According to FIG. 5b, the pull-out device 35 contains a first guide element 65, which has a second engagement element 62 that is configured to engage in the second guide recess 46 of the second connecting element arm 44 of the second frame module 40. The first guide element 65 is thus attached to the end of the first support element end section 41 of the second support element 27. The second engagement element 62 can, for example, be configured as a pin element which can slide in the guide track designed as a slot. In this embodiment, the guide track corresponds to the second guide recess 46 of the second connecting element arm 44.

[0127] According to the embodiment shown in FIG. 5a and FIG. 5b, a first guide element 65 and a second guide element 66 are provided so that the pull-out device 35 is mounted in a particularly stable manner. The second guide element 66 contains the first engagement element 61 for reception in the first guide recess 45 of the first connecting element arm 43 of the connecting element 4 of the first frame module 15 of the frame 10. The first guide element 65 contains the second engagement element 62 for reception in the second guide recess 46 of the second connecting element arm 44 of the connecting element 4 of the first frame module 15 of the frame 10. According to the embodiment shown in FIG. 5a and FIG. 5b, the first guide element 65 and the second guide element 66 are configured as tabs. The first and second engagement elements 61, 62, which can be configured as pin elements, for example, are attached to the corresponding tab. The support provided for the pull-out device 35 by the first and second guide elements 65, 66 in the upper and lower regions of the corner cabinet when installed ensures that the pull-out device 35 and the associated installation unit 20 are mounted in a manner that is stable against tilting.

[0128] In particular, the first support element end section 33 of the first support element 17 and the first connecting element end region 19 of the first support connecting element 18 are connected, and the first support element end section 41 of the second support element 27 and the second connecting element end region 29 of the first support connecting element 18 are connected. According to the embodiment shown in FIGS. 5a and 5b, a second support connecting element 28 is shown. The second support connecting element 28 has a first connecting element end region 49 and a second connecting element end region 59. According to the present embodiment, the second support element end section 34 of the first support element 17 and the first connecting element end region 49 of the second support connecting element 28 are connected, and the second support element end section 42 of the second support element 27 and the second connecting element end region 59 of the second support connecting element 28 are connected. The use of a second support connecting element 28 makes it possible to additionally stiffen the mounting frame 50, so that increased torsional stability of the first mounting frame 51 can be achieved.

[0129] The first support connecting element 18 includes a guide device 60, which is visible in FIG. 5a or FIG. 5b. The guide device 60 contains a guide element which is configured as a guide rail. The first support element 17, the second support element 27, the first support connecting element 18, and the second support connecting element 28 can be moved in the guide device 60 between a retracted state and an extended state. In other words, the mounting frame 50 is movable in the guide device 60 between a retracted state and an extended state. The first support element 17, the second support element 27, the first support connecting element 18, the second support connecting element 28, and the guide device 60 are pivotable about a vertical pivot axis in the extended state, as shown in FIG. 5a or FIG. 5b.

[0130] The pivot movement is made possible by a curved section of the first guide recess 45 and the second guide recess 46. The curved section of each of the first guide recess 45 and the second guide recess 46 allows the angular position of the mounting frame 50 visible in FIG. 5a or FIG. 5b in relation to the second frame module 40 of the frame 10, which is mounted in the side wall of the corner cabinet when installed. This allows the mounting frame 50 to be pivoted around the side wall of the corner cabinet in the same way as the first mounting frame 51 shown in FIG. 2a to 2d. The first guide element 65 connected to the mounting frame 50 can thus rotate the guide device 60 around the corresponding end of the first guide recess 45 and the second guide recess 46.

[0131] According to the present embodiment, the pull-out device 35 contains a strut 53 which comprises at least one rotary means 54 which is configured to be received in the second frame module 40 of the frame 10. The pull-out device 35 with the strut 53 can be pivoted about a vertical pivot axis. The pivot axis runs through the rotary means 54, 57. The first guide element 65 can be coupled to the strut 53 so that the first guide element 65 also pivots with the strut 53. According to this embodiment, the first guide element 65 is configured as the first pivot element. The second guide element 66 can be coupled to the strut 53 so that the second guide element 66 also pivots with the strut 53. According to this embodiment, the second guide element 66 is configured as a second pivot element.

[0132] The first support element 17 contains a handle element 55 on its second support element section 34. The handle element can be used to move the mounting frame 50 of the pull-out device 35 manually. According to the present embodiment, the guide device 60 contains a first guide rail element 63 and a second guide rail element 64. The first guide rail element 63 is connected to the strut 53. The second guide rail element 64 is attached to the first support connecting element 18. The second guide rail element 64 runs essentially from the first connecting element end region 19 to the second connecting element end region 29. In FIG. 5a, the second guide rail element 64 is not visible because it is located on the rear side of the first support connecting element 18. The rear side refers to the side of the first support connecting element 18 opposite the installation unit 20.

[0133] The mounting frame 50, which is formed by the first support element 17, the second support element 27, the first support connecting element 18, and the second support connecting element 28, is thus movable in the guide device 60. Since the first guide rail element 63 is connected to the strut 53, no guide rail is required on the cabinet base according to this embodiment. This also facilitates the installation of a coupling arrangement 36, which forms a connection to the second mounting frame 52 for a further second installation unit 30 not shown, see in particular FIG. 5a, FIG. 2a to 2d.

[0134] The pull-out device 35 according to FIG. 5a or FIG. 5b comprises the installation unit 20 with the first mounting frame 51, the handle element 55, the first guide element 56, and a coupling arrangement 36, by means of which the second installation unit 30 can be moved by means of the second mounting frame 52 when the handle element 55 is actuated by a user. The coupling arrangement 36 can be activated by moving the first mounting frame 51. The coupling arrangement 36 allows the second mounting frame 52 and thus the second installation unit 30 to be moved when the first mounting frame 51 is moved when the handle element 55 is actuated by a user to move the pull-out device 35.

[0135] According to the present embodiment, the coupling arrangement 36 comprises a first arm element 37, a second arm element 38, a third arm element 39, and a coupling element 48 connected to the frame 10. According to FIG. 5a or FIG. 5b, the coupling element 58 is connected to the second connecting element arm 44. The first arm element 37 is rotatably connected at a first end to the second installation unit 30 and at a second end to a first end of the second arm element 38. In addition, the first arm element 37 and the second arm element 38 are also connected to the coupling element 48.

[0136] The second arm element 38 is connected at a second end to a first end of the third arm element 39. The third arm element 39 is connected at a second end to the pull-out device 35. According to FIG. 5a or FIG. 5b, the third arm element 39 is connected to the first support connecting element 18. The second end of the third arm element 39 is thus moved along with the first mounting frame 51 when the pull-out device 35 is actuated.

[0137] FIG. 6a and FIG. 6b each show a perspective view of part of a second frame module 140 of a frame 10 for a corner cabinet and a pull-out device 135 according to a fourth embodiment. FIG. 6a shows a view of the pull-out device 135 in a partially swung-out state in a view from above. FIG. 6b shows a view of the pull-out device 135 in a view from below.
