Description

[0001] Translation-rotation fitting and furniture or household appliance element

[0002] The present invention relates to a translation-rotation fitting according to the preamble of claim 1 and to a furniture or household appliance element.

[0003] Generic translation-rotation fittings are known, for example, from DE 10 2019 109 866 A1 and are used in particular for the simultaneous translational and rotational movement of a first body relative to a body, for example in the form of a shelf accommodated in a furniture body.

[0004] The translational-rotation fitting described therein has proven itself in practice. The fittings of the translational-rotation fitting must be attached to the first or second cabinet with great precision to ensure collision-free movement of the second cabinet relative to the first cabinet within the available installation space. If the load is very unevenly distributed across the loading area, the movable furniture part may tilt sideways relative to the stationary furniture part, which is particularly noticeable in the joint pattern of the furniture in the closed or open position.

[0005] The object of the present invention is to provide a translation-rotation fitting with which an exact horizontal alignment of the movable furniture part is easily possible, even subsequently.

[0006] This object is achieved by a translation-rotation fitting having the features of claim 1.

[0007] A translational-rotational fitting according to the invention for at least partially forced simultaneous translational-rotational movement of a first body relative to a second body in one of two possible opposite directions of rotation and in a predetermined translational direction comprises a first fitting part coupled to the first body and a second fitting part coupled to the second body and simultaneously movable in translational and rotational directions relative to the first fitting part. An adjustment mechanism for adjusting the second fitting part relative to the second body in a predetermined adjustment direction by a limited adjustment amount is fixed to the second fitting part.

[0008] By arranging such an adjustment mechanism, precise horizontal alignment or adjustment is easily possible even after the translation-rotation fitting has been installed between the first and second body.

[0009] Advantageous embodiments are the subject of the subclaims.

[0010] According to an advantageous embodiment, a base plate of the second fitting part has a plurality of longitudinal guides extending in the adjustment direction, for example in the form of elongated holes, which enables the second fitting part to be mounted in a variable location in a simple manner.

[0011] According to a further advantageous embodiment, the second fitting part is mounted on an adjustment plate fastened to the second body so as to be displaceable in the adjustment direction.

[0012] According to a further advantageous embodiment of the translation-rotation fitting according to the invention, the adjustment mechanism has a tool holder which is rotatably fastened to the second body or the adjustment plate and which is arranged in a rotationally fixed manner on an adjusting body which is received in an adjustment mechanism holder of the second fitting part, wherein the adjusting body is shaped such that the second fitting part can be displaced by rotating the tool holder.

[0013] The provision of such an adjustment mechanism with tool holder enables the second fitting part to be adjusted relative to the second body in a simple manner even after the second fitting part has been mounted on the second body.

[0014] In an advantageous development, retaining elements, which are attached to the adjustment plate, are guided through a portion of the longitudinal guides in the base plate of the second fitting part. This allows the adjustment plate to be attached to the second body and the second fitting part to be subsequently fixed to the adjustment plate, so that no screws or the like need to be removed from the second body to align the second fitting part.

[0015] According to an advantageous design variant, the adjustment mechanism is designed as a spiral-shaped curved guide. The adjustment mechanism can also be designed as an eccentric gear or a screw drive.

[0016] The adjustment mechanism is preferably designed to be lockable in order to easily secure an adjustment position of the second fitting part relative to the second body against unintentional adjustment.

[0017] According to a further advantageous development, at least one end stop is arranged on the base plate or the adjustment plate of the second fitting part.

[0018] In a preferred embodiment, the adjustment direction is aligned in the direction of a diagonal of a mounting surface of the second body.

[0019] The furniture or household appliance element according to the invention comprises a first body and a second body movable relative to the first body. Furthermore, the furniture or household appliance element comprises a translation-rotation fitting with which the second body can be moved relative to the first body in a predetermined translation direction and simultaneously in one of two possible opposite rotation directions. The translation-rotation fitting is designed as described above.

[0020] Preferred embodiments are explained in more detail below with reference to the accompanying drawings. They show:

[0021] Figure 1 is a schematic isometric representation of a furniture or

[0022] Household appliance element with a first body and a second body movable relative to the first body in a closed position,

[0023] Figure 2 shows a representation of a furniture or household appliance element with an inclined second body, corresponding to Figure 1, Figures 3 and 4 show plan views of an embodiment variant of a translation-rotation fitting according to the invention in different positions relative to the second body, enabled by an adjustment mechanism,

[0024] Figure 5 is a plan view of a variant of a second fitting part with an adjusting plate arranged underneath,

[0025] Figure 6 is an isometric view of the arrangement shown in Figure 5,

[0026] Figure 7 is a partial exploded view of the second fitting part showing an adjustment mechanism and

[0027] Figures 8 and 9 show representations of the second fitting part corresponding to Figures 6 and 7 from a perspective rotated by 180°.

[0028] In the following description of the figures, terms such as top, bottom, left, right, front, back, etc., refer exclusively to the exemplary representation and position of the translation-rotation fitting, first fitting part, second fitting part, adjustment plate, adjustment mechanism, and the like chosen in the respective figures. These terms are not to be understood as limiting; i.e., these references may change due to different working positions or the mirror-symmetrical design, etc.

[0029] In Figures 1 and 2, the reference number 1 designates a furniture or household appliance element, here in the form of a cabinet.

[0030] The furniture or household appliance element 1 has a first body 2 and a second body 3 movable relative to the first body.

[0031] The furniture or household appliance element 1 further comprises a translation-rotation fitting 4, with which the second body 3 can be moved relative to the first body 2 in a predetermined translation direction A and simultaneously in one of two possible opposite rotation directions Ri, R2. A plan view of a variant of such a translation-rotation fitting 4 is shown in Figures 3 and 4. The basic structure of such a translation-rotation fitting is known from the above-mentioned DE 10 2019 109 866 A1. This fitting comprises rolling elements, in particular balls, which are guided in grooves.

[0032] Such a translation-rotation fitting 4 for at least partially forced simultaneous translation-rotation movement of the first body 2 relative to the second body 3 in one of two possible opposite directions of rotation Ri, R2 and in a predetermined translation direction A, has a first fitting part 5 coupled to the first body 2 and a second fitting part 6 coupled to the second body 3 and simultaneously movable in translation and rotation relative to the first fitting part 5.

[0033] In the exemplary embodiment, the translational movement is preferably made possible by a pull-out guide with a guide rail (not shown) fastened to a base plate 51 of the first fitting part 5, in the embodiment variant shown two such guide rails, each with a running rail 52 held displaceably on the guide rail in the translation direction A.

[0034] A first rotating part of a rotary bearing 9 is attached to the guide rail 52(s), which is connected to a second rotating part of the rotary bearing 9, which is attached to a rotary bearing receptacle 63. The rotary bearing can be designed, for example, as a ball head or a slewing ring.

[0035] In a preferred embodiment, the rotary bearing 9 is axially held by a spacer bolt 91 on a side of the adjusting plate 7 facing the second body 3. To enable longitudinal displacement relative to the adjusting plate 7, an elongated hole 72 in the adjusting plate 7, through which the spacer bolt 91 is guided, serves.

[0036] To enforce the translational-rotational movement of the translational-rotational fitting 4, a guide element (not shown here) is arranged, in particular fastened, on the first fitting part 5, which guide element can be moved along or (in the exemplary embodiment shown here) in a guide track 62 of the second fitting part 6. The guide track 62 is preferably shaped such that the second body 3 moves from a closed position shown in Figure 1 through a combined translational-rotational movement out of a niche in the first body 2, which is delimited here by two side walls, and is repositioned in the niche after each 90° rotation or a rotation by a multiple of 90°, in particular 180°.

[0037] By means of the adjustment mechanism 8 fixed to the second fitting part 6, the second fitting part 6 can be aligned relative to the second body 3 in a predetermined adjustment direction V by an adjustment dimension limited here by the length of longitudinal guides in the form of elongated holes 65 in the base plate 61 of the second fitting part 6. Retaining elements 10 are guided in the elongated holes 65.

[0038] Figures 3 and 4 show the second fitting part 6 in different maximum adjusted positions.

[0039] As further shown in Figures 3 and 4, the fitting part 6 is mounted diagonally on a mounting surface 31 of the second body 3.

[0040] As can be seen from Figures 5 to 9, the base plate 61 of the second fitting part 6 has a plurality of such elongated holes 65 extending in the adjustment direction V.

[0041] As can be clearly seen in Figures 7 and 9, the second fitting part 6 is preferably fastened to an adjusting plate 7 fastened to the second body 3 so as to be displaceable in the adjustment direction V. The adjusting plate 7 is fixedly fastened to the second body 3, for example by screws 11 screwed into bores 73 provided for this purpose in the mounting surface 31 of the second body 3. The holding elements 10, which are guided in the elongated holes 65, are fixed to the adjusting plate 7.

[0042] A partial number of the elongated holes 65 in the base plate 61 of the fitting part 6 enables easy accessibility to these screws 11, as can be clearly seen in Figure 5.

[0043] In order to be able to adjust the second fitting part 6 in a simple manner in the predetermined adjustment direction V, the adjustment mechanism 8 in the embodiment variant shown in Figures 5 to 9 has a tool holder 82 which is rotatably fastened to the adjustment plate 7 and which is arranged in a rotationally fixed manner on an adjusting body 81 which is received in an adjustment mechanism holder 64, shown in Figure 9.

[0044] The adjusting body 81 is shaped in such a way that the second fitting part 6 can be moved by rotating the tool holder 82.

[0045] Preferably, the adjustment is performed when the second body is in an intermediate position, since the second fitting part 6 can be easily adjusted in this position. Alternatively, the mounting surface 31 can have a through-hole corresponding to the tool holder 82 in order to easily adjust the second fitting part 6 in any position of the second body 3.

[0046] As shown in Figures 7 and 9, the adjustment mechanism 8 is designed here as a worm wheel.

[0047] As shown in Figure 9, an adjusting web 68 is formed on the base plate 61 of the second fitting part 6 and projects into the screw of the adjusting body 81.

[0048] As a result, the position of the tool holder 82 can be adjusted in the adjustment direction V by rotating the adjusting body 81.

[0049] Since the tool holder 82 is fixedly positioned in a holder 71 relatively deep to the adjusting plate 7, the rotation of the adjusting body 81 forces a movement of the base plate 61 of the second fitting part 6 in the adjustment direction V.

[0050] It is also conceivable to design the adjustment mechanism 8, for example, as a non-circular or threaded drive.

[0051] Furthermore, it is conceivable to design the adjustment mechanism 8 so that it can be locked in order to prevent the adjustment mechanism 8 from being reset unintentionally.

[0052] Both the rotary bearing holder 63 and the guide track 62 are separated from the adjusting plate 7 by a respective base 66, 67.

[0053] As further shown in Figures 3 to 9, end stops 12 are arranged on the base plate 61 or the adjusting plate 7 of the second fitting part 6 in the region of the ends of the guide track 62. In the illustrated embodiment, the end stops 12 are fixed in an end stop receptacle 74 of the adjusting plate 7. It is also conceivable to fix the end stops 12 to the base plate 61 of the second fitting part 6. In this case, the end stops 12 move with the base plate 61 when the second fitting part 6 is adjusted.

[0054] It is also conceivable to arrange such an end stop 12 only at one end of the guide track 62.
