DETAILED DESCRIPTION

[0060] In the following description of the figures, terms such as top, bottom, left, right, front, rear, etc. refer exclusively to the exemplary representation and position of the guide fitting, the furniture or household appliance element, the self-closing device, activator, guide fitting, guide cam track, linear guide and the like selected in the respective figures. These terms are not to be understood restrictively, i.e. these references may change due to different working positions or the mirror-symmetrical design or the like.

[0061] In FIGS. 1-5, the reference sign 1 is used to designate a variant of a furniture element according to the invention.

[0062] The furniture element 1 shown here essentially consists of a support body 2 with a base support plate 21, a top support plate 22, and side walls 23 connecting the base support plate 21 to the top support plate 22 as well as a body part 3 which can be moved relative to the support body 2 simultaneously in translation in a direction of translation A and in rotation in one of two possible directions of rotation R1, R2.

[0063] Instead of the side wall 23 connecting the base support plate 21 to the top support plate 22, a design variant of the support body 2 without side wall 23 is also conceivable, for example when the base support plate 21 and the top support plate 22 are attached to a building wall.

[0064] The body part 3 also has a base plate 31, a top plate 32, and a connecting element connecting the base plate 31 to the top plate 32, in the embodiment example shown in the form of at least one side wall 33.

[0065] In the embodiment shown in these figures, the shelf-like body part 3 has a square base area with two side walls 33, which close an interior space in a closed position shown in FIG. 1, and two open vertical sides, shown in FIGS. 2 and 3, which allow access to the interior space.

[0066] Instead of the side walls, it is also conceivable to connect the base plate 31 to the top plate 32 via corner posts 36, shown as an example in FIG. 3, or a central post in the middle of the surface of the base plate 31 or top plate 32.

[0067] In the embodiment shown here, the interior of the body part 3 has several shelves 35. However, other configurations or subdivisions of the interior of the body part 3 are also conceivable in principle.

[0068] As further shown in FIGS. 2, 4, and 5, a guide fitting 4 is arranged between the top support plate 22 and the top plate 32, shown in FIGS. 2 and 4, and/or between the base support plate 21 and the base plate 31, shown in FIG. 5, by means of which the simultaneous translational and rotational movement of the body part 3 relative to the support body 2 is made possible.

[0069] Preferably, the body part 3 provided here with a square base can be moved relative to the support body 2 from a first functional position into a second functional position rotated by a predetermined angle relative to the starting position, wherein in both functional positions the base (support) plates 21, 31 and the top (support) plates 22, 32 of the body part 3 and of the support body 2 are aligned in matching geometries relative to one another.

[0070] It is also conceivable, for example in the case of a body part 3 with a rectangular base and unequal side lengths, that the second rotated functional position is not congruent with the first functional position. For example, after rotating such a body part, a different depth must be approached in order to also rest against a building wall or a wall of the support body.

[0071] Preferred embodiments of such a guide fitting 4 are shown in more detail in FIGS. 6 to 16.

[0072] A first embodiment of such a guide fitting 4 is shown in FIGS. 6 to 9.

[0073] The guide fitting 4 also has a linear guide 6 with at least one first connecting part, designed here as a guide rail 61, and a second connecting part, designed here as a running rail 62, which can be moved relative to the first connecting part, one of which is fixedly coupled to the guide element 11 and the other of which is coupled to the guide cam track 5 by means of a pivot bearing 9. Other variants of a linear guide can also be used, for example a guide rail with a roller carriage that can be moved on it.

[0074] In the embodiment example shown, the pivot bearing 9 fastened to the two running rails 62 comprises a first and second mounting plate 91, 93, wherein the second mounting plate 93 is fastened to the running rails 62 and the first mounting plate 91 can be fastened correspondingly to the top plate 32 or the base plate 31 of the body part 3.

[0075] In an exemplary embodiment shown in FIG. 11, a turntable 92 is also attached to the first mounting plate 91. The mounting plates 91, 93 are mounted so that they can rotate relative to one another.

[0076] The turntable 92 and the first mounting plate 91 are preferably fastened to the base plate 31 or the top plate 32 of the body part 3, just like the guide cam track 5.

[0077] Both the guide rails 61 of the linear guide 6 and the guide element 11 are fixed to a support plate 7 in the preferred design variant of the guide fitting 4 shown here.

[0078] Alternatively, the guide rails 61, the guide element 11, and/or the self-closing devices 8 can be arranged directly on the top support plate 22 and/or base support plate 21.

[0079] To fix the guide rails 61 in place, fixing elements 73, 74 are provided on the support plate 7, with which a fixing area of the guide rails 61 can be positively fixed to the support plate 7.

[0080] As shown in FIGS. 6 to 9, the guide element 11 has a wheel 111 that can be guided in the guide groove 51 of the guide cam track 5 and which is connected via a guide neck 113 to a foot 112, which is fixed in a recess in the support plate 7 provided for this purpose.

[0081] The guide neck 113 is accommodated in a hole in the support plate 7.

[0082] Furthermore, an annular stop 114 is provided between the wheel 111 and the foot 112, which, as shown in FIG. 7, represents an additional horizontal guide for a catch element 82 of a self-closing device 8, which is described in more detail below.

[0083] As shown in FIGS. 6 and 7, a self-closing device 8 is attached to each of the ends 53, 54 of the guide cam track 5 on the side facing the support plate 7 (open side of the guide groove 51 of the guide cam track 5).

[0084] The self-closing device 8 has a housing 81 with a guide track 83 and a catch element 82 that is spring-loaded and/or damped in the guide track 83 and catches the guide element 11 in a predetermined position.

[0085] Different relative positions of the guide element 11 relative to the self-closing device 8 are shown in FIGS. 10a to 10d.

[0086] The guide track 83 of the self-closing device 8 is preferably designed here as a so-called crutch curve, with a straight linear area 831 and an angled area 832 adjoining one end of the linear area 831.

[0087] Accordingly, the catch element 82 of the self-closing device 8 is essentially U-shaped with two legs 821, 822 projecting from the guide track 83 and two guide pins 823, 824, which are guided in the guide track 83.

[0088] FIG. 10a shows a position of the guide element 11 before running into an end position, in which the guide element 11 and the catch element 82 are still decoupled.

[0089] In FIG. 10b, the guide element 11 is in engagement with the catch element 82, which is still held by the second guide pin 824 in the angled area 832 of the guide track 83.

[0090] As the guide element 11 continues to move, the second guide pin 824 is pushed into the linear area 831 of the guide track 83 and then guided beyond the position shown in FIG. 10c to the end position shown in FIG. 10d by means of a spring element engaging the catch element 82, which is not shown here.

[0091] The end position shown in FIG. 10d corresponds to the position of the guide element in FIG. 7.

[0092] The self-closing device 8 is activated in the same way at the other end 54 of the guide cam track 5, which corresponds to the position shown in FIG. 3 in relation to the body part 3 moved by the guide fitting 4.

[0093] FIG. 11 shows an alternative design variant of a guide fitting 4.

[0094] In contrast to the embodiment shown in FIGS. 6-10, an arm 52 extending outside the guide groove 51 is arranged here on the guide cam track 5, from which two activators 10 extend, which engage in self-closing devices 8, which are fastened to respective edge areas 72 of the support plate 7.

[0095] As in the first embodiment described with reference to FIGS. 6 to 10, the support plate 7 has a central area 71, to which the two guide rails 61, which are aligned parallel to one another, are attached, and two edge areas 72 with self-closing devices 8.

[0096] The self-closing devices 8 are of the same design as the self-closing devices 8 described with reference to the first embodiment example with reference to FIGS. 6 to 10.

[0097] FIGS. 12 to 18 show a further alternative embodiment of such a guide fitting 4.

[0098] In contrast to the two embodiments shown in FIGS. 6 to 11, only one self-closing device 12 is provided in this embodiment, which, as shown in FIGS. 12 to 16, is arranged on an edge area 72 of the support plate 7.

[0099] Alternatively, the self-closing device 12 can also be arranged in a central area 71 of the support plate 7, for example between the linear guides 6, as shown by way of example in FIGS. 17 and 18.

[0100] In this embodiment, the self-closing device 12 is coupled to the running rail 62 of the at least one linear guide 6. In another embodiment of the linear guide 6, the self-closing device 8, 12 could, for example, be coupled to a roller carriage.

[0101] As shown in FIGS. 12 to 16, the self-closing device 12 has a toggle lever pivotably mounted on the support plate 7 with a first lever 121 pivotably attached to the running rail 62, preferably in the form of a pendulum lever, and a second lever 122 pivotably coupled to the first lever 121 and pivotably attached to the support plate 7 via a pivot bearing 125, preferably in the form of a power lever. The self-closing device 12 is coupled during the entire movement via a connecting piece 127 to the running rail 62 as the movable connecting part of the linear guide 6. The levers 121, 122 are arranged in such a way that closing support is provided at least in the area of the end positions.

[0102] In the embodiment shown in FIGS. 17 and 18, in which the self-closing device 12 is arranged between the linear guides 6, in contrast to the embodiment shown in FIGS. 12 to 16, the second lever 122 is pivotably attached to the running rail 62 and the first lever 121 is pivotably coupled at one end to the second lever 122 and pivotably attached at its second end to the support plate 7 via a pivot bearing 125.

[0103] It is also conceivable to arrange the levers 121, 122 in such a way that closing forces act from a position of the linear guide 6 that corresponds to a rotational angle of preferably 45. The closing forces caused by the self-closing device 12 increase with further movement into the end position. Design variants are also conceivable in which the self-closing device 12 engages at even smaller angles of rotation.

[0104] Furthermore, a force accumulator 123 is held on the support plate 7, which is arranged on the second lever 122 or the first lever 121.

[0105] The coupling of the self-closing device 12 via the linear guide 6 and thus via the translational movement of the body part 3 also enables secure retraction into a respective end position of the body part 3, analogous to the embodiment variant shown in FIGS. 6 to 11, in which the self-closing device 8 is coupled via the guide cam track 5 and thus via the rotational movement of the body part 3.

[0106] Furthermore, as shown in FIGS. 12 to 18, a damping element 124 is additionally arranged between the support plate 7 and the first lever 121 or the second lever 122, with which the run-in into the end position can be damped. In this embodiment example, the force accumulator 123 and the damping element 124 are fixed to the support plate 7 via a mounting bearing 126.

[0107] It is also conceivable to supplement the self-closing device 8, 12 with at least one ejection device.

[0108] While FIGS. 12 and 13 show the positioning of the self-closing device 12 in an end position, FIGS. 15, 17 and 18 show the guide fitting in an intermediate position, corresponding approximately to the position of the body part 3 relative to the support body 2 shown in FIG. 2.

[0109] FIG. 16 shows the end position of the self-closing device 12, which has moved into the second position, corresponding to the position of the body part 3 relative to the support body 2 shown in FIG. 3.

[0110] Although the invention has been illustrated and described in detail by way of preferred embodiments, the invention is not limited by the examples disclosed, and other variations can be derived from these by the person skilled in the art without leaving the scope of the invention. It is therefore clear that there is a plurality of possible variations. It is also clear that embodiments stated by way of example are only really examples that are not to be seen as limiting the scope, application possibilities or configuration of the invention in any way. In fact, the preceding description and the description of the figures enable the person skilled in the art to implement the exemplary embodiments in concrete manner, wherein, with the knowledge of the disclosed inventive concept, the person skilled in the art is able to undertake various changes, for example, with regard to the functioning or arrangement of individual elements stated in an exemplary embodiment without leaving the scope of the invention, which is defined by the claims and their legal equivalents, such as further explanations in the description.
