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 fitting plates of the translational-rotation fitting must be attached to the first or second body with great precision to ensure collision-free movement of the second body relative to the first body within the available installation space. Furthermore, to ensure a precise joint pattern when arranging two or more such bodies guided by a translational-rotation fitting.

[0005] The object of the present invention is to provide a translation-rotation fitting with which the alignment in the horizontal plane can be easily adjusted 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 plate coupled to the first body and a second fitting plate coupled to the second body and simultaneously movable translationally and rotationally relative to the first fitting plate. At least one displaceably fixed adjustment arrangement is provided on the first fitting plate for independently aligning the first fitting plate relative to the first body in two mutually perpendicular adjustment directions in the plane of the translational-rotational movement of the first body relative to the second body by a limited adjustment amount.

[0008] With such a slidably fixed adjustment arrangement, alignment in the horizontal plane is easily possible even after installation of the translation-rotation fitting between the first and second body.

[0009] The adjustment arrangement can be designed differently.

[0010] Thus, according to an advantageous embodiment, the adjustment arrangement comprises a sliding element that is held on the first body so as to be displaceable in the first adjustment direction and is held on the first fitting plate so as to be displaceable in the second adjustment direction. The adjustment arrangement further comprises at least two adjustment units for adjusting the first fitting plate in the first adjustment direction and the second adjustment direction.

[0011] According to a preferred development, the sliding element is designed as a base plate with a plurality of first elongated holes aligned in the first adjustment direction and a plurality of second elongated holes aligned in the second adjustment direction, wherein first holding elements fastened to the first body are guided through the first elongated holes and second holding elements fastened to the first fitting plate are guided through the second elongated holes, which are designed in particular as bolts or screws.

[0012] With such a sliding element designed as a base plate, the first fitting plate can be easily adjusted together with the base plate relative to the first body in a first adjustment direction and can be adjusted relative to the base plate itself in the second adjustment direction.

[0013] According to a preferred development, the base plate has a first collar which is operatively connected to the first adjusting unit and oriented perpendicular to the first adjusting direction and has a threaded bore, and a second collar which is operatively connected to the second adjusting unit and oriented perpendicular to the second adjusting direction and has a threaded bore, wherein a first adjusting screw which is held stationary on the first body is received in the threaded bore of the first collar and a second adjusting screw which is held stationary on the first fitting plate is received in the threaded bore of the second collar.

[0014] For the vertical fixation of the translation-rotation fitting to the first body, the adjustment arrangement according to a further preferred embodiment has a first holder and a second holder which are positioned between the base plate and the first fitting plate and serve for the displaceable mounting of the base plate to the first body, wherein the first holder has a stop for the stationary but rotatable mounting of the first adjusting screw.

[0015] According to an alternative embodiment, the sliding element is designed as a guide cross with a first web aligned in the first adjustment direction and a second web aligned in the second adjustment direction. The first web is slidably received in a groove of a base plate attached to the first body, and the second web is guided in a groove of a sliding plate attached to the first fitting plate.

[0016] According to a preferred further development, the two actuating units are fixed to the base plate and the sliding plate.

[0017] According to a further development, the adjusting units have two adjusting bodies connected to each other by a respective adjusting screw, the distance between which can be adjusted by turning the adjusting screw.

[0018] The groove of the sliding plate is covered towards the first fitting plate with a cover plate attached to the base plate and is thus particularly protected against the ingress of dust or dirt.

[0019] According to a further alternative embodiment, the adjustment arrangement comprises two first L-shaped sliding elements held on the first body so as to be displaceable in the first adjustment direction, as well as two second L-shaped sliding elements held on the first body so as to be displaceable in the second adjustment direction, wherein the first sliding elements are aligned perpendicular to the second sliding elements. Even with an adjustment arrangement designed in this way, an alignment of the first fitting plate relative to the first body is easily possible.

[0020] According to an advantageous further development of this design variant, the sliding elements are slidably accommodated in holding elements attached to the first body using adjusting screws.

[0021] The adjusting screws are designed, for example, as eccentric screws that protrude into elongated holes in a leg of the sliding elements that protrudes into the respective holding element.

[0022] In all the previously described variants of translation-rotation fittings, the first fitting plate and the second fitting plate of the translation-rotation fitting each have grooves in mutually facing bearing surfaces in which rolling elements are guided for simultaneous translation-rotation movement.

[0023] According to a further alternative embodiment, the sliding element is designed as a guide cross with a first web aligned in the first adjustment direction and a second web aligned in the second adjustment direction, wherein the first web is slidably received in a groove of a base plate fastened to the first body in the first adjustment direction and the second web is guided in a groove of the first fitting plate.

[0024] This design variant is particularly suitable for a translational-rotational fitting, in which a guide element is arranged on the first fitting plate for simultaneous translational-rotational movement. This guide element can be moved along a curved guide track arranged on or in the second plate. The previously described design variants can also be used for a translational-rotational fitting with a guide element and a curved guide track.

[0025] According to a preferred development of this embodiment of the translation-rotation fitting, the adjusting units have two adjusting bodies connected to one another by a respective adjusting screw, the distance between which can be adjusted by turning the adjusting screw, wherein a first adjusting body is fastened to the first fitting plate and a second adjusting body is fastened to the base plate, and the adjusting screws are aligned orthogonally to one another. According to a further preferred development, the base plate and the first fitting plate have respective guide slots for receiving rivets that fix the base plate and the first fitting plate to one another in a direction perpendicular to the plane of the base plate, said rivets extending in one of the adjusting directions, wherein partially overlapping guide slots are aligned in different adjusting directions.

[0026] A furniture or household appliance element according to the invention comprises a first body and a second body movable relative thereto, as well as 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, wherein the translation-rotation fitting is designed as described above.

[0045] 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, base plate, holder, sliding plate, guide cross, 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.

[0046] In Figures 1 and 7, the reference numeral 1 denotes a furniture or household appliance element 1, which here consists of a first body 2, a second body 3, and a translation-rotation fitting 100 arranged between the first and second bodies. The first body 2 can, as shown in Figures 1 and 7, be a support plate or a section of the base of a cabinet or shelving unit. A corresponding furniture element is shown, for example, in DE 10 2019 109 866 A1.

[0047] Accordingly, the second body 3 can also be designed as a panel. However, it is also conceivable that the second body 3 could be designed as a shelving unit with several shelves or storage areas stacked vertically.

[0048] It is important that the second body 3 is movable relative to the first body 2 in a partially forced, simultaneous translational-rotational movement relative to the first body 2, specifically in one of two possible opposite directions of rotation Ri, R2 and in a predetermined translational direction A, as also described by way of example in the aforementioned DE 10 2019 109 866 A1. Figures 1-16b show several embodiments of translational-rotational fittings 100, 200, 300, 400. What all of these translation-rotation fittings 100, 200, 300, 400 have in common is that they have a first fitting plate 110, 210, 310, 410 coupled to the first body 2 and a second fitting plate 120, 220, 420 coupled to the second body 3.An adjustment arrangement is displaceably fixed to the first fitting plate 110, 210, 310, 410, which serves for the independent alignment of the first fitting plate 110, 210, 310, 410 relative to the first body 2 in two mutually perpendicular adjustment directions x, y in the plane of the first body 2, usually a horizontal plane, by a limited adjustment dimension.

[0049] A first embodiment of a translation-rotation fitting 100 is shown in Figures 1-6d.

[0050] In this embodiment, the two mounting plates 110, 120 each have grooves 112, 122 in mutually facing bearing surfaces for simultaneous translational-rotational movement, in which rolling elements 131 are guided. In the embodiment shown here, the rolling elements 131 are designed as balls that are captively received in a rolling element cage 130. It is also conceivable for the rolling elements to be designed as ball rollers with a cylindrical housing and a ball mounted therein, or the like.

[0051] In addition to the design of the running grooves 112, 122, the predetermined translation direction A is guided by a guide pin 113 which is held stationary but rotatable in the second fitting plate 120 and which can be moved linearly on a carriage 114 guided in a longitudinal groove of the first fitting plate 110.

[0052] The adjustment arrangement, which serves for the exact alignment of the first fitting plate 110 relative to the first body 2, has a sliding element which is held on the first body 2 so as to be displaceable in the first adjustment direction x and which is held on the first fitting plate 110 so as to be displaceable in the second adjustment direction y, as well as at least two adjustment units 4, 5 for adjusting the first fitting plate 110 in the first adjustment direction x and the second adjustment direction y.

[0053] In the embodiment of the translation-rotation fitting 100 shown in Figures 1-6d, the sliding element is designed as a base plate 140. The base plate 140 has a plurality of first elongated holes 141 aligned in the first adjustment direction x and a plurality of second elongated holes 145 aligned in the second adjustment direction y, as can be clearly seen, for example, in the view of the translation-rotation fitting 100 from below shown in Figure 4 with the first body 2 hidden.

[0054] First retaining elements 101, attached to the first body 2, are guided through the first elongated holes 141. Second retaining elements 102, attached to the first fitting plate 110, are guided through the second elongated holes 145. The retaining elements 101 and the retaining elements 102 are designed, in particular, as bolts or screws, as shown by way of example in Figure 2. The elongated holes 145 are preferably formed in the region of a bulge 144 of the base plate 140 in order to accommodate heads 103 of the retaining elements 102 above the upper side of the first body 2 facing the base plate 140.

[0055] The adjusting units 4, 5, with which the first fitting plate 110 can be aligned or adjusted relative to the first body 2, consist in the embodiment variant shown here of a first collar 142 and a second collar 143, which are bent from the plane of the base plate 140 in the z-direction perpendicular to the plane of the base plate 140, as well as a respective first adjusting screw 104 and second adjusting screw 105.

[0056] The first collar 142, which is oriented perpendicular to the first adjustment direction x, and the second collar 143, which is oriented perpendicular to the second adjustment direction y, each have a threaded bore which engages with the thread of the respective first adjustment screw 104 and second adjustment screw 105.

[0057] A head or collar piece of the first adjusting screw 104 is fixed in a stationary but rotatable manner to the first body 2. This fixation is achieved here via a first holder 150 of the adjustment assembly, which is positioned between the base plate 140 and the first fitting plate 110 and serves to slidably mount the base plate 140 to the first body 2. As can be clearly seen in Figure 3, a stop 151 with a through-bore 152 accessible from a lateral edge is arranged in this holder 150.

[0058] The first holder 150 and a second holder 160, also shown in Figures 2 and 3, are fixed in place to the first body 2 by means of the first holding elements 101. By turning the first adjusting screw 104, the base plate 140 can be adjusted in the x-direction relative to the first holder 150 and thus relative to the first body 2 by an adjustment dimension essentially limited by the extension of the threaded portion of the first adjusting screw 104 in the x-direction.

[0059] The second adjusting screw 105 is held fixedly but rotatably by its head or a collar piece on a collar 111 of the first fitting plate 110, which extends vertically, i.e., in the z-direction. By turning the second adjusting screw 105, this collar 111 is pulled toward or moved away from the second collar 143 of the base plate 140 in the y-direction.

[0060] Figures 5a-5c and 6a-6d show different positionings of the first fitting plate 110 relative to the first body 2. In Figures 5a-5c, the relative position is shown in the plan view of the base plate from the side of the first body 2, corresponding to Figure 4. Thus, Figure 5a shows a position shifted from a neutral position in the y-direction, while the alignment in the x-direction is neutral.

[0061] Figure 5b shows a neutral y-position and a maximum displacement of the first fitting plate 110 in the x-direction.

[0062] Figure 5c shows a maximum displacement of the first fitting plate 110 in both the x and y directions.

[0063] In the side views in Figures 6a - 6d, Figure 6a shows a neutral position with the first body 2 and the second body 3 arranged exactly one above the other, while Figures 6b - 6d show different displacement positions.

[0064] In the second embodiment of a translation-rotation fitting 200 according to the invention shown in Figures 7-9, the actual translation-rotation fitting with first fitting plate 210 and second fitting plate 220 and rolling elements arranged therebetween is identical to the embodiment described with reference to Figures 1-6.

[0065] Here, too, the adjustment arrangement comprises a sliding element, which in this case is designed as a guide cross 240. The guide cross 240 comprises a first web 241 oriented in the first adjustment direction x and a second web 242 oriented in the second adjustment direction y. The two webs 241, 242 are preferably glued or welded together, or manufactured as a single piece.

[0066] The first web 241 is slidably received in a groove 251 of a base plate 250 attached to the first body 2 in the first adjustment direction x. The second web 242 is guided in a groove 261 of a sliding plate 260 attached to the first fitting plate 210.

[0067] The adjusting units 4, 5 preferably used in this embodiment consist of two adjusting bodies 270, 271 connected to one another by a respective adjusting screw 272, the distance between which can be adjusted by turning the adjusting screw 272. As shown in Figures 7 and 8, the two adjusting units 4, 5 are fixedly secured to the base plate 250 with their first adjusting body 270 and to the sliding plate 260 with their second adjusting body 271.

[0068] Preferably, the groove 261 and the second web 242 of the guide cross 240 received therein to the first fitting plate 210 are covered by a cover plate 252 which is fastened to the base plate 250 via two fixing arms.

[0069] As shown in Figures 9a and 9b, the first adjusting body 270 has two grooves 273, 274, which serve to fix the adjusting screw 272 in a stationary but rotatable manner. Turning the adjusting screw 272 thus pulls the second adjusting body 271 toward or away from the first adjusting body 270.

[0070] In the embodiment of the translation-rotation fitting 300 shown in Figures 10-13, the adjustment arrangement has two first L-shaped sliding elements 350 held on the first body 2 so as to be displaceable in the first adjustment direction x, and two second L-shaped sliding elements 360 held on the first body 2 so as to be displaceable in the second adjustment direction y, wherein the first sliding elements 350 are aligned perpendicular to the second sliding elements 360. Here, too, the actual translation-rotation fitting with the first fitting plate 310 and a second fitting plate (not shown here) is designed analogously to the embodiment described in Figures 1-6.

[0071] Only on the underside of the first fitting plate 310 facing the first body 2, as shown in Figure 11, guide bushings 311, 312 are formed or fastened, in which the second leg 352, 362 of the L-shaped sliding elements 350, 360 is received and is displaceable in the longitudinal direction of the respective guide bushing 311, 312.

[0072] The respective first leg 351, 361 is preferably aligned perpendicular to the respective second leg 352, 362 of the respective sliding element 350, 360.

[0073] The first legs 351, 361 of the sliding elements 350, 360 are received in holding elements 340 fastened to the first body 2. The holding elements 340 also have guide bushings for guiding the first legs 351, 361, as shown by way of example in Figures 13a and 13b.

[0074] In order to align the first fitting plate 310 relative to the first body 2, the sliding elements 350, 360 are slidably received in the holding elements 340 fastened to the first body 2 by means of adjusting screws 370.

[0075] In the embodiment shown in Figures 13a and 13b, the adjusting screws 73 are designed as eccentric screws that project into elongated holes in a leg 351, 361 of the sliding elements 350, 360 that projects into the respective holding element 340, so that turning the eccentric screw causes a linear displacement movement in the direction of the first leg 351 of the sliding elements 350, 360. Due to the perpendicular alignment of the second legs 352, 362, which are received in correspondingly aligned sleeves 311, 312 on the underside of the first fitting plate 310 facing the first body 2, the first fitting plate 310 is displaced in the direction of the longitudinal extent of the first leg 351, 361 of the respective sliding elements 350, 360.

[0076] Figures 12a-12e show different displacement positions of the first fitting plate 310 relative to the holding elements 340 fixedly mounted on the first body 2. In this embodiment, instead of the adjusting screws 370 designed as eccentric screws in Figures 12a and 12b, adjusting screws 370 are shown which extend through the second leg 352, 362 of the respective sliding element 350, 360, wherein the second legs 352, 362 are provided with internal threads here, so that turning the adjusting screws 370 causes a translational movement of the sliding element 350, 360 in the direction of the longitudinal extent of the second leg 352, 362. The adjusting screw 370 is held stationary but rotatable on the first fitting plate 310.

[0077] In the alternative embodiment according to Figures 12c, 12d and 12e, the adjusting screw 370 engages in a threaded bore of a collar 314 of the first fitting plate 310, similar to the embodiment shown in Figures 1 - 6, and is fixed with its head or a collar piece in a stationary but rotatable manner to the holding element 340.

[0078] Figure 12c shows a middle or neutral position of the adjustment arrangement, while figures 12d and 12e show respective maximum adjustment positions.

[0079] Figures 11 a - 11 c also show respective different adjustment positions of the first fitting plate 310 relative to the holding elements 340 fixedly attached to the first body 2.

[0080] In the alternative embodiment shown in Figures 14 - 16b, a guide element 430 is arranged on the first fitting plate 410 for simultaneous translational-rotational movement, which guide element can be moved in a curved guide track 421 arranged on or in the second fitting plate 420. The translational movement is guided by a pull-out guide rotatably attached to the second fitting plate 420, preferably with two guide rails 401 and guide rails 402 guided therein for displacement in the translation direction A, as shown in Figure 15. A rotation bearing 403 is received in a corresponding receptacle 422 in the second fitting plate 420 and coupled to the guide rails 402 of the pull-out guide via a coupling piece 404.

[0081] As further shown in Figures 14, 15, 16a and 16b, in this embodiment of the translation-rotation fitting 400, the sliding element is designed analogously to the embodiment described with reference to Figures 7 - 9 as a guide cross 440 with a first web 441 aligned in the first adjustment direction x and a second web 442 aligned in the second adjustment direction y.

[0082] The first web 441 is slidably received in a groove 451 of a base plate 450 attached to the first body 2 in the first adjustment direction x. The second web 442 is guided in a groove 411 of the first fitting plate 410.

[0083] In this embodiment, the adjusting units 4, 5 used in the embodiment described in Figures 7-9 are also preferably used, each of which has two adjusting bodies 470, 471 connected to one another by a respective adjusting screw 472, the distance between which can be adjusted by turning the adjusting screw 472.

[0084] A first adjusting body 470 is attached to the base plate 450, while the respective second adjusting body 471 is attached to the fitting plate 410. The alignment of the adjusting units 4, 5 also relates to the alignment of the longitudinal axis of the adjusting screws 472, with the adjusting screw of the first adjusting unit 4 being aligned orthogonally to the adjusting screw 472 of the second adjusting unit 5.

[0085] As further shown in Figures 14 and 15, the base plate 450 and the first fitting plate 410 have respective guide slots 412, 452 for receiving rivets 460 that fix the base plate 450 and the first fitting plate 410 to one another in a direction z perpendicular to the plane of the base plate 450. The guide slots 412, 452 each extend in one of the adjustment directions x, y, wherein partially overlapping guide slots 412, 452, through which a common rivet 460 is passed, are aligned in different adjustment directions x, y.

[0086] Figures 16a and 16b show different positions of the base plate 450, which in this case is preferably fixed to the second body 3, relative to the first fitting plate 410. List of reference symbols
