Description

[Technical Field]

[0001] The invention relates to a translation-rotation fitting according to the preamble of claim 1 and to a piece of furniture or household appliance. [Background technology]

[0002] A translational-rotational fitting of this type is known, for example, from DE 10 2019 109 866 A1 and is used in particular for simultaneous translational and rotational movement of a first body relative to a second body, for example in the form of a shelf attached to a furniture body.

[0003] The translation-rotation fitting described here has proven itself in practice. The fittings of the translation-rotation fitting must be attached to the first and second bodies very precisely to ensure collision-free movement of the second body relative to the first body within the available installation space. If the load is distributed very unevenly across the load surface, the movable furniture part may tilt sideways relative to the fixed furniture part, which is particularly noticeable in furniture joint patterns when the furniture is closed or open. Summary of the Invention [Problem to be solved by the invention]

[0004] SUMMARY OF THE INVENTION It is an object of the present invention to provide a translation-rotation fitting which makes it easy to achieve accurate horizontal alignment of movable furniture parts even afterwards. [Means for solving the problem]

[0005] This object is solved by a translation-rotation fitting having the features of claim 1.

[0006] A translation-rotation fitting according to the present invention for at least partially active simultaneous translation-rotational movement of a first body relative to a second body in one of two possible opposite rotational directions 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 capable of simultaneous translational and rotational movement relative to the first fitting part.

[0007] An adjustment mechanism is secured to the second mating portion, and the adjustment mechanism adjusts the second mating portion relative to the second body in a predetermined adjustment direction by a limited amount of adjustment.

[0008] Such an adjustment mechanism arrangement allows for easy achievement of precise horizontal alignment or adjustment between the first body and the second body, even after the translation-rotation fitting is attached.

[0009] Advantageous embodiments are the subject matter of the dependent claims.

[0010] According to one advantageous embodiment, the base plate of the second mating part has several longitudinal guides, for example in the form of elongated holes, extending in the adjustment direction, which allow the second mating part to be easily mounted in variable positions.

[0011] According to a further advantageous embodiment, the second fitting is attached to an adjustment plate attached to the second body and can be moved 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 rotatably mounted on the second body or adjustment plate, which is arranged to be rotatably fixed on an adjustment body received in the adjustment mechanism holder of the second fitting, the adjustment body being shaped so that the second fitting can be displaced by rotating the tool holder.

[0013] By providing such an adjustment mechanism having a tool holder, it becomes possible to easily adjust the second fitting portion relative to the second main body even after the second fitting portion has been attached to the second main body.

[0014] In an advantageous further development, the holding element fastened to the adjusting plate is guided through some of the longitudinal guides in the base plate of the second fitting element.

[0015] This allows the adjustment plate to be fixed to the second body, and then the second fitting portion to be fixed to the adjustment plate, eliminating the need to loosen screws or the like from the second body to align the second fitting portion.

[0016] According to one advantageous embodiment, the adjustment mechanism is configured as a helical cam guide. The adjustment mechanism can also be configured as an eccentric gear or screw drive.

[0017] The adjustment mechanism is preferably configured to be lockable so that the position of the second fitting portion relative to the second body, once adjusted, can be easily fixed against unintentional adjustment.

[0018] According to a further advantageous refinement, at least one end stop is arranged on the base plate or on the adjusting plate of the second fitting. In a preferred embodiment, the adjustment direction is aligned with the diagonal direction of the mounting surface of the second body.

[0019] The furniture or household appliance according to the invention has a first body and a second body movable relative to the first body. Additionally, the furniture or household appliance may have a translation-rotation fitting that allows the second body to be simultaneously moved in a predetermined translational direction relative to the first body and in one of two possible opposite rotational directions, the translation-rotation fitting being configured as described above. [Brief explanation of the drawings]

[Figure 9] 8 is a perspective view of the second fitting portion corresponding to FIG. 7 rotated by 180°. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0021] In the following description of the drawings, terms such as top, bottom, left, right, front, back, etc. refer solely to exemplary representations and positions of the translation-rotation fittings, first fittings, second fittings, adjustment plates, adjustment mechanisms, etc. selected in the respective drawings. These terms should not be understood as limiting, i.e., their references may vary for different working positions or mirror symmetric configurations, etc.

[0022] In Figures 1 and 2, the number 1 refers to a piece of furniture or household appliance, here in the form of a cabinet. The furniture or household appliance 1 has a first body 2 and a second body 3 that is movable relative to the first body.

[0023] The furniture or household appliance 1 also has a translation-rotation fitting 4 by means of which the second body 3 can simultaneously move in a predetermined translation direction A relative to the first body 2 and in one of two possible opposite rotation directions R1 and R2.

[0024] A top view of an embodiment of such a translation-rotation fitting 4 is shown in Figures 3 and 4. The basic design of such a translation-rotation fitting is known from the above-mentioned German Patent Publication 10 2019 109 866. This fitting has rolling elements, in particular balls guided in raceways.

[0025] Such a translation-rotation fitting 4 for at least partially actively performing simultaneous translation-rotational movement of a first body 2 relative to a second body 3 in one of two possible opposite rotational directions R1, R2 and in a predetermined translational 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 movable simultaneously in translation and rotation relative to the first fitting part 5.

[0026] In the embodiment, the translational movement is preferably made possible by an extension guide with guide tracks (not shown) fastened to the base plate 61 of the first fitting part 5, and in the embodiment shown, each of two such guide tracks comprises a running rail 52 held displaceably on the guide track in the translational direction A.

[0027] A first rotating part of the rotary bearing 9 is fixed to the running rail 52, which is connected to a second rotating part of the rotary bearing 9 fixed to a rotary bearing mounting part 63. The rotary bearing can be configured, for example, as a ball head or a slewing ring.

[0028] In a preferred embodiment, the rotation bearing 9 is held axially on the side of the adjusting plate 7 facing the second body 3 by a spacer bolt 91. The slots 72 in the adjusting plate 7, through which the spacer bolts 91 are guided, serve to allow longitudinal displacement relative to the adjusting plate 7.

[0029] In order to actively guide the translational-rotational movement of the translational-rotational fitting 4, a guide element, not shown here, is further arranged on the first fitting part 5, in particular fixed, and can be moved along or (in the embodiment shown here) along the guide track 62 of the second fitting part 6.

[0030] The guide track 62 is preferably shaped so that, from the closed position shown in FIG. 1, the second body 3 moves by a combination of translational and rotational movements out of the niche of the first body 2 (here delimited by two side walls) and positions itself back in the recess after each 90° rotation or multiple of 90°, in particular 180° rotation.

[0031] An adjustment mechanism 8 fixed to the second fitting 6 allows the second fitting 6 to be aligned relative to the second body 3 in a predetermined adjustment direction V by an amount of adjustment limited by the length of a longitudinal guide in the form of an elongated hole 65 in the base plate 61 of the second fitting 6. The holding element 10 is guided in the elongated hole 65.

[0032] 3 and 4 show the second mating part 6 in different maximum adjustment positions. Furthermore, as shown in FIGS. 3 and 4, the second fitting portion 6 is attached to the attachment surface 31 of the second main body 3 at an angle. As can be seen from FIGS. 5 to 9, the base plate 61 of the second fitting portion 6 has several such elongated holes 65 extending in the adjustment direction V.

[0033] As is clear from FIGS. 7 and 9, the second fitting portion 6 is preferably attached to an adjustment plate 7 fixed to the second body 3 so as to be movable in the adjustment direction V. The adjusting plate 7 is fixed to the second body 3, for example, by means of screws 11 which are screwed into holes 73 provided for this purpose in the mounting surface 31 of the second body 3. Holding elements 10, guided in the elongated holes 65, are fixed to the adjusting plate 7.

[0034] Several slots 65 in the base plate 61 of the fitting 6 allow easy access to these screws 11, as can be clearly seen in FIG. In order to easily adjust the second fitting portion 6 in the predetermined adjustment direction V, the adjustment mechanism 8 of the embodiment shown in FIGS. 5 to 9 has a tool holder 82 rotatably fixed to the adjustment plate 7, and the tool holder 82 is rotatably fixed and arranged on an adjustment body 81 housed in the adjustment mechanism holder 64 shown in FIG. 9.

[0035] The adjustment body 81 is configured so that the second fitting portion 6 is displaced by rotating the tool holder 82. The adjustment is preferably performed when the second body is in an intermediate position, and the second fitting 6 can be easily adjusted in this position. Alternatively, the mounting surface 31 may have a through hole corresponding to the tool holder 82, so that the second fitting 6 can be easily adjusted at any position of the second body 3.

[0036] As shown in Figures 7 and 9, the adjustment mechanism 8 is configured here as a worm gear. As shown in FIG. 9, an adjustment bar 68 is formed on the base plate 61 of the second fitting portion 6, and the adjustment bar 68 protrudes into the worm gear of the adjustment body 81.

[0037] This allows the position of the tool holder 82 to be adjusted in the adjustment direction V by turning the adjustment body 81. Since the tool holder 82 is fixed relatively deep within the holder 71 relative to the adjustment plate 7, the rotation of the adjustment body 81 forcibly moves the base plate 61 of the second fitting portion 6 in the adjustment direction V.

[0038] It is also conceivable to configure the adjustment mechanism 8 as, for example, a non-circular or threaded drive. It is also possible to configure the adjustment mechanism 8 to be lockable, thereby preventing the adjustment mechanism 8 from being reset accidentally.

[0039] Both the rotary bearing mount 63 and the guide track 62 are separated from the adjusting plate 7 by respective bases 66, 67. Furthermore, as shown in FIGS. 3 to 9, in the region of the ends of the guide tracks 62, end stops 12 are arranged on the base plate 61 of the second fitting part 6 or on the adjusting plate 7. In the illustrated embodiment, the end stop 12 is fixed to an end stop receiving portion 74 of the adjusting plate 7 .

[0040] It is also possible to fix the end stopper 12 to the base plate 61 of the second fitting portion 6. In this case, when the second fitting portion 6 is adjusted, the end stopper 12 moves together with the base plate 61. It is also conceivable to arrange such an end stop 12 only at one end of the guide track 62 . [Explanation of symbols]
