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, such as those known from DE 10 2019 109 866 A1, which serve to enable simultaneous translational and rotational movement of a first body relative to a second body, for example, in the form of a shelf mounted in a furniture body, have proven themselves in practice. Such translation-rotation fittings are typically fixed to the first body with a first fitting part.

[0004] Depending on the design of the furniture or household appliance element, it may be necessary to align the translation-rotation fitting in its mounting plane, which can be relatively complex in the case of direct mounting on the first furniture body depending on the assembly progress of the furniture, as individual components may have to be dismantled again before alignment.

[0005] The object of the present invention is to provide a translation-rotation fitting with which the alignment in the horizontal plane is easily possible even subsequently, and to provide an easily adjustable furniture or household appliance element with such a translation-rotation fitting.

[0006] The stated objects are achieved by a translation-rotation fitting having the features of claim 1 and by a furniture or household appliance element having the features of claim 15.

[0007] A translation-rotation fitting according to the invention for at least partially forced simultaneous translation-rotation movement of a first body relative to a second body in one of two possible opposite directions of rotation and in a predetermined translation direction has a first fitting part coupled to the first body and a second fitting part coupled to the second body and simultaneously movable in translation and rotation relative to the first fitting part.

[0008] At least one adjustment arrangement, which can be actuated with an auxiliary tool, is arranged on the first fitting part for the independent alignment of the first fitting part relative to the first body in at least one of two mutually perpendicular adjustment directions in the plane spanned by the translation direction and the rotation directions by a limited adjustment dimension.

[0009] With such an adjustment arrangement arranged on the translation-rotation fitting, it is possible in a simple manner to align the translation-rotation fitting between the first and second body in the horizontal plane.

[0010] In addition, the adjustment with the adjustment arrangement also makes it easy to adjust an aperture gap.

[0011] Advantageous embodiments of such an adjustment arrangement are specified in the subclaims.

[0012] According to a preferred embodiment, the adjustment arrangement of the translation-rotation fitting comprises a base plate arranged on the first body and a carrier plate arranged on the first fitting part.

[0013] According to a preferred development, the adjustment arrangement comprises a first slider which is held displaceably in a recess of the base plate in the second adjustment direction and a second slider which is coupled to the first slider and arranged displaceably in the first adjustment direction relative to the base plate.

[0014] A first lever, which is fixed but pivotably coupled to the first slider, for adjusting the support plate relative to the base plate in the first adjustment direction, and a second lever, which is fixed but pivotably coupled to the base plate, for adjusting the support plate relative to the base plate in the second adjustment direction, are also components of this preferred development of the adjustment arrangement. The adjustment arrangement further comprises a plurality of guide pins fixedly held on the second slider, which extend through elongated holes in the base plate extending in the second adjustment direction into elongated holes in the support plate extending in the first adjustment direction, wherein the first lever and the second lever have a receptacle for inserting and / or securing the auxiliary tool.

[0015] According to a further preferred embodiment, in order to lock the adjustment arrangement, the first lever can be locked by means of a locking element on the first slide and the second lever can be locked by means of a locking element on the base plate.

[0016] According to a preferred development, a respective locking element is resiliently mounted in the region of the respective receptacle of the first and second lever, so that the locking element is pressed or pulled into a locking position without external force.

[0017] In a preferred embodiment, locking teeth are formed on the first slide and in a region of the base plate on which the receptacle of the second lever for inserting the auxiliary tool is positioned, which locking teeth can be brought into engagement with locking teeth of a locking strip of the locking element, wherein the locking strip is disengaged from the locking teeth when the auxiliary tool is inserted into the receptacle of the first or second lever.

[0018] This means that the locking of the respective lever can be easily released by inserting the auxiliary tool when an adjustment is intended.

[0019] In an alternative embodiment of the translational-rotational fitting according to the invention, the adjustment assembly comprises an intermediate plate arranged between the base plate and the carrier plate, as well as two base holders attached to the base plate, each of which holds a sliding element displaceably in one of the adjustment directions. The carrier plate is held on the intermediate plate displaceably in a first adjustment direction, and the intermediate plate is held on the base plate displaceably in a second adjustment direction.

[0020] The sliding elements have a receptacle for inserting and / or fixing the auxiliary tool, wherein the sliding element received in the first basic holder is fixedly coupled to the intermediate plate or the carrier plate and the sliding element received in the second basic holder is fixedly coupled to the other of the intermediate plate or the carrier plate.

[0021] An adjustment arrangement designed in such an alternative manner also enables the alignment of the second object coupled to the carrier plate in a simple manner.

[0022] In a preferred embodiment of this adjustment arrangement, the sliding elements have at least one web aligned perpendicular to the intended adjustment direction, which protrudes in a form-fitting manner into a web receptacle of the intermediate plate or the carrier plate.

[0023] This allows the intermediate plate (together with the support plate) to be moved relative to the base plate or the support plate to be moved relative to the intermediate plate in a simple manner by moving the sliding element.

[0024] In this embodiment of the adjustment arrangement, the sliding elements have a clamping web for locking a preset position of the carrier plate, which protrudes into a clamping device accommodated in the respective base holder.

[0025] This allows a continuous adjustment of the adjustment arrangement

[0026] In a preferred development, each of the clamping devices has two ball carriers, each with a ball held therein, which are held in a respective recess of the base holder so as to be displaceable in the respective adjustment direction.

[0027] The balls are each mounted in a conical section of the respective recess and can be moved by moving the ball carriers from a clamping position, which clamps the clamping bar of the respective sliding element, to a release position, in which the balls release the clamping bar. According to another alternative embodiment, the clamping of the sliding elements can be designed such that the sliding elements can be clamped to the base holder by means of a clamping element.

[0028] The clamping element is held here in a clamping element receptacle of the base holder so as to be displaceable in the direction of adjustment, whereby the sliding element clamps against a friction edge of the base holder in a direction perpendicular to the direction of adjustment.

[0029] In this design variant, the sliding element must be pushed forward a little way perpendicular to the sliding direction in the insertion direction using the auxiliary tool in order to unlock it, in order to release the clamping by the clamping element and then to carry out the sliding movement in the desired adjustment direction in this advanced position.

[0030] According to an alternative embodiment, each of the clamping devices has two clamping body supports, each with a clamping body held therein, which are held displaceably in a respective recess of the base holder in the respective adjustment direction, wherein the clamping bodies are each mounted in a conical section of the respective recess and can be moved by moving the clamping body supports from a clamping position clamping the clamping web of the respective sliding element into a release position not clamping the clamping web of the respective sliding element.

[0031] The clamping bodies are preferably designed as cylinders, rollers, sliding pieces or wedges.

[0032] In a further preferred embodiment, the auxiliary tool has an actuating tongue that can be inserted into the receptacles of the first or second lever.

[0033] In a first preferred embodiment, the actuating tongue of the auxiliary tool inserted into the respective receptacle can be pulled out again from the respective receptacle.

[0034] This allows the auxiliary tool to be easily removed from the fitting after adjustment. In an alternative design, the auxiliary tool's actuating tongue, inserted into the respective receptacle, is fixed in the respective receptacle.

[0035] A particularly preferred variant is one in which the actuating tongue of the auxiliary tool is coupled to a handle via a folding mechanism.

[0036] This ensures that the auxiliary tool is always accessible. Thanks to the folding mechanism, it can be easily folded into a slot between the top or bottom edge of a front or side panel of the second cabinet and the floor or ceiling of the first cabinet when not in use.

[0037] According to a further preferred embodiment, the first and second fitting parts are designed as first and second fitting plates, which each have grooves in mutually facing bearing surfaces in which rolling elements are guided for simultaneous translational-rotational movement.

[0038] An alternative translational-rotational fitting 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 has a guide element on the first fitting part for the simultaneous translational-rotational movement, which guide element can be moved in a curved guide track arranged on or in the second fitting part.

[0039] The 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.

[0040] The translation-rotation fitting is designed as described above.

[0062] 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 adjustment assembly, the body, the translation-rotation fitting, the base plate, support plate, slider, lever, 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.

[0063] In Figures 1, 2a, and 2b, the reference numeral 1 denotes a furniture or household appliance element. The furniture or household appliance element 1 comprises a first body 2 with a base 21 and a top 22, and a second body 3 movable relative to this base, wherein the base 21 and the top of the first body 2 overlap the second body 3.

[0064] For the movement of the second body 3, represented in Fig. 3a by a simple plate, relative to the first body 2, a translation-rotation fitting 4 is provided between the first body 2 and the second body 3. The fitting comprises a first fitting part 41 designed as a fitting plate, a second fitting part 42 also designed as a fitting plate, a plurality of rolling elements 44, and a rolling element cage 43 that holds the rolling elements 44 relative to one another in a predetermined position. The first fitting part 41 and the second fitting part 42 advantageously have running grooves for the rolling elements.

[0065] Alternatively, the superimposed translational-rotary movement of the second body 3, also represented by a simple plate in Fig. 3b, relative to the first body 2 can be realized by a translational-rotary fitting 4' with a first fitting part 41, a second fitting part 42, a linear guide 45, a guide track 46, a guide element and a slewing ring 47. Instead of the slewing ring 47, a ball head or similar can also be used. The first fitting part 41 is designed here in the form of holding webs of two guide rails of the linear guide 45, on which guide rails can be moved in the translation direction A. For example, a plate-shaped design of the first fitting part 41, to which the guide rails are fastened or molded, is also conceivable. A linear guide 45 with only one or more than two guide rails is also conceivable.

[0066] Furthermore, as can be seen in Fig. 3a or Fig. 3b, an adjustment arrangement 100 or 200 is fastened to the first body 2, the support plate 120 of which, as will be explained below, is adjustable relative to a base plate 110 in a horizontal plane and which can be fixed in place on the first fitting part 41 of the translation-rotation fitting 4, 4' in order to be able to align the translation-rotation fitting 4, 4' in the horizontal xy plane after mounting the adjustment arrangement 100 or 200 and the translation-rotation fitting 4, 4' between the first body 2 and the second body 3. The adjustment in the horizontal xy-plane can be enabled in the x-direction or in the y-direction; preferably, an adjustment is enabled in both the x-direction and the y-direction and is described below.

[0067] The translation-rotation fitting 4, 4' is characterized in that the second body 3 is movable relative to the first body 2 in a partially forced, simultaneous translation-rotation movement relative to the first body 2, specifically in one of two possible opposite directions of rotation Ri, R2 and in a predetermined translation direction A, as also described by way of example in DE 10 2019 109 866 A1. A first embodiment of the orientation of the translation-rotation fitting 4, 4' in the xy plane is shown in an exploded view in Fig. 4.

[0068] As can be seen here, this first embodiment variant of the adjustment arrangement 100 has a base plate 110 that can be fastened to the first body 2 and a carrier plate 120 that can be fastened to the first fitting part 41 of the translation-rotation fitting 4, 4'.

[0069] The base plate 110 has a slider receptacle 111 in which a first slider 130 is received, which is held displaceably relative to the base plate 110 in the second adjustment direction y.

[0070] Furthermore, a second slider 140 is provided on the base plate 110 and is also displaceable relative to the base plate 110 in the second adjustment direction y. For guidance in the second adjustment direction y, a guide cylinder 115 is arranged on the base plate 110 and projects into an elongated hole 146 in the second slider 140 extending in the second adjustment direction y.

[0071] This second slider 140 is essentially L-shaped, with a first leg 142 and a second leg 143 which is aligned approximately perpendicular to the first leg 142.

[0072] From the second leg 143, a tongue 144 extends approximately halfway along the length of the second leg 143, with a bore in which a pivot pin 131 of the first slide 130 is received, so that when the first slide 130 is moved in the second adjustment direction y, the second slide 140 also moves.

[0073] The adjustment arrangement 100 further comprises a first lever 150, which is fixed but pivotably coupled to the first slide 130, for adjusting the carrier plate 120 relative to the base plate 110 in the first adjustment direction x, and a second lever 160, which is fixed but pivotably coupled to the base plate 110, for adjusting the carrier plate 120 relative to the base plate 110 in the second adjustment direction y.

[0074] On the second slide 140, a plurality of fixed guide pins 180 are fastened in bores 147 provided for this purpose, which extend through elongated holes 112 of the base plate 110 extending in the second adjustment direction y into elongated holes 122 of the carrier plate 120 extending in the first adjustment direction x.

[0075] The first lever 150 and the second lever 160 each have a receptacle 151, 161 for inserting and / or fixing an auxiliary tool 9.

[0076] The auxiliary tool 9 is designed as a flat component and has a handle 92 and an actuating tongue 91. This makes it possible for the auxiliary tool 9, as shown in Figures 2a and 2b, to be inserted through a slot 5 remaining between an upper or lower edge of a front or side panel 31 of the second body 3 and a base 21 or a ceiling 22 of the first body 2 in a closed position of the second body 3 shown in Figures 1, 2a and 2b, and thus the adjustment arrangement 100 is accessible in any position of the second body and in particular in the closed position of the second body.

[0077] A horizontal alignment of the second body 3 relative to the first body 2 in the closed position is particularly advantageous, as it allows adjustment of the joint pattern in the closed position of the furniture or household appliance element 1 without having to disassemble or move parts for access to the adjustment. Another advantage is that it allows immediate verification of whether the adjustment has led to the desired result.

[0078] In the inserted state of the respective auxiliary tool 9, the side edges extending in the longitudinal direction of the auxiliary tool 9 of an actuating tongue 91 which can be inserted into the receptacles 151, 161 are aligned parallel to the side walls of the receptacle 151, 161, as can be seen by way of example in Fig. 8. In the preferred embodiment according to Fig. 4-14, these side edges of the actuating tongue 91 rest on the side edges of a locking element 170 which serves to lock the adjustment arrangement 100, ie the first lever 150 and the second lever 160.

[0079] The locking elements 170 are inserted into the receptacles 151, 161 of the first lever 150 and the second lever 160, respectively. To adjust the support plate 120 in the first adjustment direction x or the second adjustment direction y, the levers 150, 160 are rotated about their respective pivot points using the auxiliary tools.

[0080] The pivot point of the first lever 150 is the pivot pin 131 of the first slide 130, which projects into a pin receptacle 153 in the region of an end of the first lever 150 remote from the receptacle 151.

[0081] The pivot point of the second lever 160 is a pivot pin 114 which is formed on the base plate 110.

[0082] For adjusting the support plate 120 in the first adjustment direction x, a driver web 121 protrudes from the support plate 120 through an elongated hole 132 in the first slide 130 extending in the first adjustment direction x into an elongated hole 152 of the first lever 150 extending in the second adjustment direction y and an elongated hole 145 in the second slide 140.

[0083] In the assembled state, the side edges of this driver web 121 rest against the side longitudinal edges of the elongated hole 152 of the first lever 150, so that by pivoting the first lever 150 with the pivoting movement, the elongated hole 152 is displaced in the first adjustment direction and in the process takes the driver web 121 and thus the carrier plate 120 along in the first adjustment direction x.

[0084] As can be further seen in Fig. 4, a driver web 141 projects from the second slide 140 into an elongated hole 162 of the second lever 160 extending in the first adjustment direction x.

[0085] Accordingly, when the second lever 160 pivots over the driver web 141, the side edges of which rest against the side longitudinal edges of the elongated hole 162 of the first lever 160, the second slide 140 is also moved in the second adjustment direction y (relative to the base plate 110).

[0086] To lock the adjustment assembly 100 in a desired position, locking elements 170 are provided. Each locking element 170 is fixed in place in the area of ​​the respective receptacle 151, 161 of the first and second levers 150, 160.

[0087] In order to lock the levers 150, 160 in a predetermined position, locking teeth 113, 133 are formed on the first slide 130 and in a region of the base plate 110 on which the receptacle 161 of the second lever 160 for inserting the auxiliary tool 9 is positioned, which can be brought into engagement with locking teeth of a locking strip 171 of the locking element 170.

[0088] When the auxiliary tool 9 is inserted into the receptacle 151, 161 of the first or second lever 150, 160, the locking bar 171 is disengaged from the locking teeth 113, 133, the base plate 110 or the first slide 130.

[0089] The actuating tongue 91 of the auxiliary tool 9, in the position inserted into the receptacle 151, 161, presses the locking strip 171 of the respective locking element 170 out of the plane of the locking teeth 113, 133.

[0090] Figure 5 shows, by way of example, an adjustment arrangement 100 fastened to a first body 2, in which one of two auxiliary tools 9 is inserted into one of the receptacles 151, 161 of the first or second lever 150, 160.

[0091] From the position of the guide pins 180 in the elongated holes 122 of the support plate 120, it can be seen that the support plate 120 is in a neutral position in the first adjustment direction x, which can also be seen from the central position of the auxiliary tool 9.

[0092] Instead of auxiliary tools 9, which can be inserted into the receptacles 151, 161 provided for this purpose as required, the actuating tongues 91 of the auxiliary tools 9 are permanently fastened in the receptacles 151, 161 in an alternative embodiment, as shown in Figures 5a and 5b.

[0093] In this embodiment, the auxiliary tool 9 is designed with a handle 92 that can be folded relative to the actuating tongue 91. For this purpose, the handle 92 is connected via a folding mechanism 93 to the actuating tongue 91, which is permanently accommodated in the respective receptacle 151, 161. This makes it possible to fold the handle 92 into the slot 5 when not in use, as shown in Figure 5b. To operate the auxiliary tool 9, one can preferably slightly slide or rotate the second furniture part relative to the first furniture part 2 in order to gain access to the handle 92.

[0094] Alternatively, it is also conceivable to additionally provide the folding mechanism with a push-to-open mechanism, so that if necessary, by pressing the side edge of the handle 92 near the outer edge of the first body 2 further into the slot 5, the handle 92 folds out from the position shown in Figure 5b into the position shown in Figure 5a by triggering the push-to-open mechanism, in order to thus enable adjustment of the first fitting part 41.

[0095] Figure 8 shows, by way of example, an adjusted position of the carrier plate 120 by pivoting the second lever 160, which is accompanied by a displacement of the carrier plate 120 in the second adjustment direction y.

[0096] Figures 9 to 14 show further different adjustment positions of the carrier plate 120 relative to the base plate 110 and their release by actuating the corresponding levers 150, 160.

[0097] An alternative preferred embodiment of an adjustment arrangement according to the invention is shown in Figures 15 to 25.

[0098] As is shown in particular in the exploded views according to Figures 17 and 18, this embodiment variant of the adjustment arrangement 200 also has a base plate 210 that can be fastened to the first body 2 and a support plate 220 that can be fastened to the second body 3.

[0099] In contrast to the adjustment assembly 100 shown in Figures 1 to 14, this adjustment assembly 200 has an intermediate plate 230 arranged between the base plate 210 and the carrier plate 220 to enable displacement in the two adjustment directions x, y. The intermediate plate 230 thus enables, on the one hand, an adjustment of the carrier plate 220 relative to the intermediate plate 230 and, on the other hand, an adjustment of the intermediate plate 230 relative to the base plate 210, in which the carrier plate 220 is moved along with the intermediate plate 230.

[0100] As can be further seen in Figures 15, 17 and 18, the adjustment arrangement 200 has two basic holders 240, 250 fastened to the base plate 210, in each of which a sliding element 260 is slidably received in one of the adjustment directions x, y in a sliding element receptacle 241.

[0101] The carrier plate 220 is held displaceably on the intermediate plate 230 in a first adjustment direction x, while the intermediate plate 230 is held displaceably on the base plate 210 in a second adjustment direction y. For displaceably holding the carrier plate 220 on the intermediate plate 230 in the first adjustment direction x, as shown in Figures 15 and 17, elongated holes 221 extending in the first adjustment direction x are provided, into which bolts 201 provided with a mushroom head and fastened to the intermediate plate 230 are received.

[0102] Accordingly, the base holders 240, 250 have bolts 246, 256 on their side facing the intermediate plate 230, which are received in elongated holes 231 of the intermediate plate 230, which extend in the second adjustment direction y, in order not to hinder a displacement of the intermediate plate in the second adjustment direction relative to the base plate 210.

[0103] The sliding elements 260 have, similar to the levers 150, 160 or the locking element 170 of the first embodiment, a receptacle 261 for inserting the auxiliary tool 9.

[0104] The sliding element 260 received in the first base holder 240 is fixedly coupled to the intermediate plate 230 and the sliding element 260 received in the second base holder 250 is fixedly coupled to the carrier plate 220.

[0105] This makes it possible to move the respective sliding element

[0106] 260 is accompanied by a displacement of the intermediate plate 230 or the support plate 220. For the stationary fixation of the sliding elements 260 to the intermediate plate 230 or the support plate 220, the sliding elements 260 have at least one web or webs 262, in the illustrated embodiment two, oriented perpendicular to the intended adjustment direction x, y, which protrude or protrude in a form-fitting manner in a web receptacle 222, 232 of the intermediate plate 230 or the support plate 220.

[0107] The web receptacles 222, 232 are designed as slot-shaped recesses in the carrier plate 220 and the intermediate plate 230, respectively.

[0108] The web receptacles 232 of the intermediate plate 230 are, as shown in Figure 17, preferably formed in a region 233 of the intermediate plate 230 which is slightly raised compared to the remaining surface of the intermediate plate 230, in order to lie in a recess 244 of the first base holder 240 in the assembled state, in which it is guided by side edges 245 of the recess 244 in the second adjustment direction y.

[0109] The sliding elements 260 further preferably have a clamping web 263 which projects into a clamping device 270 received in the respective base holder 240.

[0110] This clamping device 270 has two ball carriers 271, each holding a ball 272. Depending on the design, more than two balls 272 can be arranged in one ball carrier 271.

[0111] The ball carriers 271 with the respective ball 272 fixedly fixed to the ball carrier 271 are held displaceably in the respective adjustment direction x, y in a respective recess 242, 252 of the base holder 240, 250, shown by way of example in Figure 18 using the first base holder 240.

[0112] One of the base holders 240, 250, here the base holder 250, is preferably designed in two parts, with a first part held on the base plate 210, into which a second part 255 can be inserted, wherein the recesses 252 are introduced into the second part 255. The balls 272 are each mounted in a conical section 243, 253 of the respective recess 242, 252 and can be moved by sliding the ball carriers 271 from a clamping position clamping the clamping web 263 of the respective sliding element 260 into a release position not clamping the clamping web 263 of the respective sliding element 260.

[0113] As can be seen in particular in Figure 18 and Figures 21b, 22b, 23b, 24b and 25b, the ball carriers 271 are moved away from each other in the direction of the longitudinal extent of the clamping web 263 in order to release the clamping web 263.

[0114] The recesses 242, 252 of each of the base holders 240, 250 are formed in pairs and mirror-symmetrically to a central imaginary mirror axis oriented perpendicular to the longitudinal direction of the clamping web 263.

[0115] This arrangement of the recesses 242, 252 has the advantage that the ball carriers 271 can be moved from the clamping position into the release position by inserting the auxiliary tool 9 into the receptacle 261 of the sliding element 260 and can be moved from the release position back into the clamping position under spring load after removing the auxiliary tool 9 from the receptacle 261 of the sliding element 260.

[0116] For spring loading, as shown by way of example in Figure 18, spring elements 273, in particular in the form of compression springs, are provided, which are accommodated in receptacles provided for this purpose in the ball carrier 271 and are supported on the one hand on an inner wall within the receptacle of the ball carrier 271 and on the other hand on a rear wall of the respective recess 242, 252 extending perpendicular to the adjustment direction x, y, so that the ball carrier 271 is always pressed into the clamping position by the force of the spring element 273.

[0117] In an alternative embodiment, it is also conceivable to use other clamping bodies with corresponding clamping body carriers instead of the ball carriers 271 with balls 272 accommodated therein.

[0118] Cylinders, rollers, sliding pieces, or wedges, which are accommodated in correspondingly designed clamping body supports, are particularly conceivable as clamping bodies. Figure 19a shows a plan view from below of the adjustment arrangement 200, in which one of the two auxiliary tools 9 is inserted into the receptacle 261 of one of the sliding elements 260.

[0119] The auxiliary tool 9 is positioned here in a neutral position in the sliding element 260, which is coupled to the intermediate plate 230, so that by pivoting the auxiliary tool 9, a displacement of the intermediate plate and with it the carrier plate 220 takes place in the second adjustment direction y, as can be seen in Figure 19b.

[0120] In a corresponding manner, Figure 19c shows an exclusive adjustment of the carrier plate 220 in the adjustment direction x and Figure 19d shows an adjustment of the carrier plate 220 in the adjustment direction x and additionally an adjustment of the carrier plate 220 together with the intermediate plate 230 in the adjustment direction y.

[0121] As further shown in Figures 20a and 20b, the ball supports 271 of the clamping device 270 serve not only to hold the clamping balls 272 but also as a stop or pivot point of the auxiliary tool 9 used as a lever in order to enable adjustment of the support plate 220 with as little effort as possible.

[0122] For this purpose, the ball carriers 271 have insertion bevels 274 to facilitate the insertion of the actuating tongue 91 of the auxiliary tool 9 and the pushing apart of the clamping devices 270 arranged in pairs.

[0123] Adjacent to the insertion bevels 274 is an approximately circular-segment-shaped pivot point region 275, against which side edges of the actuating tongue 91 rest and which form the pivot point when the auxiliary tool 9 is pivoted in the plane spanned by the adjustment directions x, y, with which a displacement of the respective sliding element 260 and thus of the intermediate plate 230 and / or the carrier plate 220 is effected.

[0124] Figures 21a, 21b to 25a, 25b illustrate the release of the sliding element 260 associated with the sliding movement by the displacement of the ball carriers 271 and, with them, of the balls 272 held by the ball carriers 271. Figure 21a shows the sliding element 260 in a neutral position before the intermediate plate is moved in the adjustment direction y or counter to the adjustment direction y, as well as the clamping device 270 consisting of the two ball carriers 271 in the clamping position, in which the clamping web 263 of the sliding element 260 is clamped by the balls 272 and thereby prevents unintentional or accidental adjustment in or counter to the adjustment direction y.

[0125] Figure 21 b shows a partial sectional view to illustrate the four balls 272 clamping the clamping web 263, which are pushed forward by the spring elements 273 into the conical section 243, 253 of the respective recess 242, 252 so far that they clamp the clamping web 263.

[0126] Figures 22a and 22b show the auxiliary tool 9 inserted into the receptacle 261 of the sliding element 260 in the neutral position.

[0127] As can be clearly seen here, the ball carriers 271 are moved into the release position by inserting the auxiliary tool 9.

[0128] As can be seen from Figure 22b, the balls 272 are moved into the further widened area of ​​the conical section 243, so that the clamping web 263 is no longer clamped by the balls 272 and does not hinder an intended sliding movement of the sliding element 260.

[0129] Figures 23a and 23b show a sliding element 260 displaced counter to the adjustment direction y.

[0130] As can be seen from Figure 23b, the balls 272 are still in the release position which does not clamp the clamping web 263.

[0131] Figures 24a and 24b show a representation corresponding to Figures 23a and 23b with the sliding element 260 displaced in the adjustment direction y.

[0132] Figures 25a and 25b show a sliding element 260 displaced in the adjustment direction y after removal of the auxiliary tool 9 from the receptacle 261 of the sliding element 260. As can be seen in particular from Figure 25b, by removing the auxiliary tool 9, the balls 272 together with the ball carriers 271 have been pressed back into the clamping position in which the clamping web 263 is held in its current position by the spring force of the spring elements 273.

[0133] Figures 26 to 31 show another alternative embodiment variant concerning the locking of the sliding element 260'.

[0134] In this embodiment, the head 262' of the sliding element 260' projects into a recess 231' of the intermediate plate 230' which is adapted to the intended adjustment direction x, y, wherein the parallel side edges 263' of the head 262' of the sliding element 260' rest against the side edges of the intermediate plate 230.

[0135] Accordingly, the carrier plate 220 is also designed with a web or head holder instead of the two web holders (not shown further here).

[0136] The clamping of the sliding element 260' is effected here by a clamping element 280, as shown by way of example in Figure 27.

[0137] This clamping element 280 has a base body 281 which is inserted into a clamping element receptacle 241' of the base holder 240' which extends in the adjustment direction x, y and from which two curved arms 282 extend, at the ends of which clamping sleeves 283 are formed which, in the assembled state, are positioned on both sides of the head 262' of the sliding element 260' and protrude into a groove 242' parallel to the clamping element receptacle 241' of the base holder 240'.

[0138] In the clamping position, as shown by way of example in Figure 28, the clamping sleeves 283 rest between a shoulder 266' of the sliding element 260' and conical clamping surfaces 232' outside the recess 23T of the intermediate plate 230', so that with the aid of the sliding element 260' and the clamping sleeves 283, a displacement of the intermediate plate 230 in the adjustment direction x, y is prevented.

[0139] To release this clamping, as shown in Figure 29, the sliding element 260 is pushed further into the recess of the intermediate plate 230' in a direction perpendicular to the intended adjustment direction x, y by inserting the auxiliary tool 9.

[0140] As a result, the clamping sleeves 283 are pressed outwards from the shoulder 266' of the sliding element 260' via a bevelled area 264' and thus out of the clamping area between the side edge of the groove 242' of the base holder 240' and the conical clamping surfaces 232' clamping the clamping sleeves 283 into a widened area in which the clamping sleeves 283 are pressed through the widened space between the side edge of the groove 242' of the base holder 240' and the conical clamping surfaces 232' clamping the clamping sleeves 283, whereby the clamping of the intermediate plate 230' and the sliding element 260' is released.

[0141] Figure 29 already shows a sliding element 260' adjusted in the direction y.

[0142] Figure 30 shows a sliding element 260' adjusted counter to the adjustment direction y and Figure 31 shows the sliding element displaced according to Figure 30 with the auxiliary tool removed, in which the sliding element 260' is pushed back into the clamping position by the spring force of the spring arms 282 of the clamping element 280.

[0143] The pivot points for the auxiliary tool 9 are formed here by the inner edges of the base holder 240' which are further apart.
