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 general translation-rotation fitting, such as that known from DE 10 2019 109 866 A1, is used and has proven itself in practice for simultaneous translational and rotational movement of a first body relative to a second body, for example in the form of a shelf housed in a furniture body. Such a translation-rotation fitting is usually fixed to the first body by means of a first fitting.

[0003] Depending on the configuration of the furniture or household appliance, it may be necessary to align the translation-rotation fitting in its mounting plane, which, if mounted directly on the first furniture body, may be relatively time-consuming depending on the progress of the furniture assembly, and individual components may have to be disassembled again before alignment. Summary of the Invention [Problem to be solved by the invention]

[0004] The object of the present invention is to provide a translation-rotation fitting which still allows alignment in a horizontal plane in a simple manner, and further to provide an easily adjustable piece of furniture or household appliance having such a translation-rotation fitting. [Means for solving the problem]

[0005] The set object is solved by a translation-rotation fitting having the features of claim 1 and by a piece of furniture or household appliance having the features of claim 15.

[0006] The translation-rotation fitting according to the present invention is adapted to simultaneously perform translation-rotational movement of a first body relative to a second body that is at least partially reliably guided in one of two possible opposite rotational directions and in a predetermined translational direction, and has a first mating part coupled to the first body, and a second mating part coupled to the second body that is capable of simultaneous translational and rotational movement relative to the first mating part.

[0007] At least one adjustment device that can be operated by an auxiliary tool is arranged on the first mating portion, thereby allowing the first mating portion to be independently aligned relative to the first body by a limited adjustment dimension in at least one of two mutually perpendicular adjustment directions in a plane spanning the translational and rotational directions.

[0008] By arranging such an adjustment device on the translation-rotation fitting, the translation-rotation fitting of the first body and the second body can be aligned in a simple manner in the horizontal plane. Furthermore, adjustment by means of the adjustment device also makes it possible to adjust the gap of the opening in a simple manner. Advantageous embodiments of such a regulation device are set forth in the dependent claims.

[0009] According to a preferred embodiment, the adjustment device of the translation-rotation fitting comprises a base plate arranged on the first body and a carrier plate arranged on the first fitting portion.

[0010] According to a preferred further development, the adjustment device has a first slider displaceably held in a recess of the base plate in the second adjustment direction, and a second slider coupled to the first slider and arranged displaceably relative to the base plate in the first adjustment direction.

[0011] A first lever fixed but pivotally connected to the first slider for adjusting the carrier plate relative to the base plate in a first adjustment direction, and a second lever fixed but pivotally connected to the base plate for adjusting the carrier plate relative to the base plate in a second adjustment direction are part of this preferred further development.

[0012] Furthermore, the adjustment device is fixedly held on the second slider and has a plurality of guide bolts extending through elongated holes in the base plate extending in the second adjustment direction and into elongated holes in the carrier plate extending in the first adjustment direction, and the first lever and the second lever have receiving portions for inserting and / or fixing auxiliary tools.

[0013] According to a further preferred embodiment, the first lever can be latched to the first slider by a latch element and the second lever can be latched to the base plate by a latch element to lock the adjustment device.

[0014] According to a preferred further development, the respective latch elements are resiliently mounted in the area of ​​the respective receiving parts of the first and second levers, so that the latch elements can be pushed or pulled into the latched position without external forces.

[0015] In a preferred embodiment, latch teeth are formed on the first slider and in the region of the base plate in which the receiving part of the second lever for inserting the auxiliary tool is positioned, which teeth can engage with latch teeth of a latch strip of the latch element, which latch strip disengages from the latch teeth when the auxiliary tool is inserted into the receiving part of the first lever or the second lever. This allows the respective lever to be unlocked simply by inserting an auxiliary tool when the intended adjustment is to be made.

[0016] In an alternative embodiment of the translation-rotation fitting according to the invention, the adjustment device comprises an intermediate plate arranged between the base plate and the carrier plate, and two base holders attached to the base plate, each holding a sliding element movable in one of the adjustment directions. The carrier plate is slidably held on the intermediate plate in a first adjustment direction, and the intermediate plate is slidably held on the base plate in a second adjustment direction.

[0017] The slide elements have receiving portions for inserting and / or fixing auxiliary tools, and the slide elements held in the first base holder are statically coupled to the intermediate plate or carrier plate, and the slide elements held in the second base holder are statically coupled to the other of the intermediate plate or carrier plate.

[0018] Such an alternative adjustment device also allows the second body coupled to the carrier plate to be aligned in a simple manner. In a preferred embodiment of this adjustment device, the sliding element has at least one web that is aligned perpendicular to the intended adjustment direction and projects securely into a web receiving portion of the intermediate plate or carrier plate.

[0019] This allows the intermediate plate (together with the carrier plate) to be moved relative to the base plate, or the carrier plate to be moved relative to the intermediate plate, simply by moving the sliding element. In a variant of the configuration of this adjusting device, the sliding elements have clamping webs which project into clamping devices accommodated in the respective base holders and lock the carrier plate in a preset position.

[0020] This allows the adjustment device to be adjusted steplessly. In a preferred further development, each of the clamping devices has two ball carriers, each holding a ball therein, which are held in respective recesses in the base holder and are displaceable in respective adjustment directions.

[0021] The balls are each mounted in a conical portion of a respective recess and are moved by sliding the ball carrier from a spring-loaded clamping position in which it clamps the clamping web of the respective slide element to a release position in which it does not clamp the clamping web of the respective slide element and the balls release the clamping web.

[0022] According to a further alternative embodiment, the clamping of the slide element can be configured such that the slide element is clamped to the base holder by the clamping element. The clamping element is here held in a clamping element receiving portion of the base holder, whereby the clamping element can be displaced in the adjustment direction, whereby the sliding element is pressed against the friction edge of the base holder in a direction perpendicular to the adjustment direction.

[0023] Therefore, in this variant of the configuration, in order to release the clamping by the clamping element and perform a displacement movement in the desired adjustment direction in this advanced position, it is necessary to use an auxiliary tool to push the slide element slightly forward perpendicular to the displacement direction in the insertion direction.

[0024] According to an alternative embodiment, each clamp device has two clamp body carriers each holding a clamp body, and these clamp body carriers are held displaceably in each adjustment direction in respective recesses of the base holder, and the clamp bodies are respectively attached to the conical portions of the respective recesses, and can be moved by displacing the clamp body carriers from a clamping position in which they clamp the clamp webs of the respective slide elements to a release position in which they do not clamp the clamp webs of the respective slide elements.

[0025] The clamp body is preferably configured as a cylinder, roller, slide or wedge. In a further preferred embodiment, the auxiliary tool has an actuation tongue that can be inserted into the receiving part of the first or second lever. In a first preferred embodiment, the actuation tongues of the auxiliary tools inserted in the respective holders can be pulled out again from the respective holders.

[0026] That is, once the fitting is adjusted, the auxiliary tool can be easily removed from the fitting. In an alternative embodiment, the actuation tongue of the auxiliary tool inserted in the respective holder is fixed to the respective holder. A variant in which the actuating tongue of the auxiliary tool is connected to the handle via a folding mechanism is particularly preferred.

[0027] This means that the auxiliary tool is always available. The folding mechanism allows the auxiliary tool to be easily folded into a slot between the top or bottom edge of the front or side panel of the second body and the base or ceiling of the first body when not in use.

[0028] According to a further preferred embodiment, the first mating part and the second mating part are configured as first and second mating plates, each having running grooves on their opposing bearing surfaces for simultaneous translational-rotational movement, in which the rolling elements are guided.

[0029] An alternative translation-rotation fitting for simultaneously performing translation-rotational movement of a first body relative to a second body that is at least partially reliably guided in one of two possible opposite rotational directions and in a predetermined translational direction has a guide element for the simultaneous translation-rotational movement on the first body, which guide element can be moved in a curved guide track arranged on or in the second fitting.

[0030] The furniture or household appliance according to the invention has a first body and a second body movable relative to the first body, and a translation-rotation fitting, whereby the second body can move in a predetermined translational direction relative to the first body and simultaneously in one of two possible opposite rotational directions. The translation-rotation fitting is constructed as described above. [Brief explanation of the drawings]

[0032] In the following description of the figures, terms such as top, bottom, left, right, front, back, etc. refer exclusively to exemplary representations and positions of selected adjustment devices, bodies, translation-rotation fittings, base plates, carrier plates, sliders, levers, etc. in the respective figures. These terms should not be understood in a limiting manner, i.e., their references may change with different working positions or mirror symmetric configurations, etc.

[0033] In Figures 1, 2a and 2b, the number 1 designates as a whole a piece of furniture or household appliance. The furniture or household appliance 1 here comprises a first body 2 having a base 21 and a top 22, and a second body 3 movable relative to the base, with the base 21 and the top of the first body 2 overlapping the second body 3.

[0034] To move the second body 3, represented by a simple plate in Fig. 3a, relative to the first body 2, a translation-rotation fitting 4 is provided between the first body 2 and the second body 3, said translation-rotation fitting 4 comprising a first fitting part 41 configured as a fitting plate, a second fitting part 42 configured as a fitting plate, a plurality of rolling elements 44 and a rolling element cage 43 which holds the rolling elements 44 in position relative to one another. Advantageously, the first fitting part 41 and the second fitting part 42 have running grooves for the rolling elements.

[0035] Alternatively, the superimposed translation-rotation movement of the second body 3 relative to the first body 2, shown by a simple plate in Figure 3b, can be realized by a translation-rotation fitting 4, which comprises a first fitting 41, a second fitting 42, a linear guide 45, a guide track 46, a guide element and a swivel head 47. Furthermore, instead of the swivel head 47, a ball head or the like can also be used. The first fitting 41 is here configured in the form of a retaining web for the two guide rails of the linear guide 45, on which the running rail can be displaced in the translation direction A. For example, it is also conceivable for the first fitting 41, on which the guide rails are attached or molded, to have a plate-like configuration. Linear guides 45 with only one or more guide rails are also conceivable.

[0036] Furthermore, as shown in Figure 3a or 3b, the adjustment device 100 or 200 is attached to the first body 2, and its carrier plate 120 is adjustable relative to the base plate 110 in a horizontal plane, as described below, and is fixed to a fixed position on the first fitting 41 of the translation-rotation fitting 4, 4' so that the translation-rotation fitting 4, 4' can be aligned in the horizontal xy plane after the adjustment device 100 or 200 and the translation-rotation fitting 4, 4' are attached between the first body 2 and the second body 3 in the horizontal xy plane. Adjustment in the horizontal xy plane can be in the x or y direction, and preferably in both the x and y directions, as described below.

[0037] The translational-rotational fitting 4, 4' is characterized in that the second body 3 is movable relative to the first body 2 in a simultaneous translational-rotational movement that is partially constrained relative to the first body 2, i.e. in a predetermined translational direction A in one of two possible opposite rotational directions R1, R2, as also exemplarily described in DE 10 2019 109 866 A1. A variant of the first embodiment of the alignment of the translation-rotation fittings 4, 4' in the xy plane is shown in FIG. 4 in an exploded view. As can be seen, this first embodiment of the adjustment device 100 has a base plate 110 that can be fixed to the first body 2 and a carrier plate 120 that can be fixed to the first fitting 41 of the translation-rotation fitting 4, 4'. The base plate 110 has a slider receiving portion 111 in which the first slider 130 is housed, and the first slider 130 is held so as to be displaceable relative to the base plate 110 in the second adjustment direction y.

[0038] Furthermore, a second slider 140 is provided which is arranged on the base plate 110 and which is further displaceable in a second actuation direction y relative to the base plate 110. For guiding in the second actuation direction y, a guide cylinder 115 is arranged on the base plate 110, which protrudes into an elongated hole 146 of the second slider 140 which extends in the second actuation direction y. This second slider 140 is here essentially L-shaped, having a first leg 142 and a second leg 143 aligned substantially perpendicular to the first leg 142.

[0039] A tongue 144 having a hole extends from the second leg 143 almost partially along the second leg 143, and this hole receives the pivot pin 131 of the first slider 130, so that when the first slider 130 is moved in the second positioning direction y, the second slider 140 also moves.

[0040] Furthermore, the adjustment device 100 has a first lever 150 that is fixedly but pivotally connected to the first slider 130 and adjusts the carrier plate 120 relative to the base plate 110 in a first adjustment direction x, and a second lever 160 that is fixedly but pivotally connected to the base plate 110 and adjusts the carrier plate 120 relative to the base plate 110 in a second adjustment direction y.

[0041] A number of fixed guide bolts 180 are attached to the second slider 140 in holes 147 provided for this purpose, which extend through slots 112 in the base plate 110 extending in the second positioning direction y and into slots 122 in the carrier plate 120 extending in the first positioning direction x. The first lever 150 and the second lever 160 have receiving portions 151, 161 for inserting and / or fixing the auxiliary tool 9, respectively.

[0042] The auxiliary tool 9 is configured as a flat component and has a handle 92 and an actuation tongue 91. This allows the auxiliary tool 9 to be inserted through the slot 5 remaining between the upper or lower edge of the front or side panel 31 of the second body 3 and the base 21 or ceiling 22 of the first body 2 when the second body 3 is in the closed position shown in Figures 1, 2a and 2b, as shown in Figures 2a and 2b, and therefore the adjustment device 100 is accessible in any position of the second body, particularly when the second body is in the closed position.

[0043] The horizontal alignment of the second body 3 relative to the first body 2 in the closed position is particularly advantageous as this makes it possible to adjust the joint pattern in the closed position of the furniture or household appliance 1 without having to disassemble or move parts for accessibility in order to make the adjustment. Another advantage is that it is possible to immediately check whether the adjustment has produced the desired result.

[0044] In the inserted state of the respective auxiliary tool 9, the side edges of the actuating tongue 91 insertable into the receiving part 151, 161, extending in the longitudinal direction of the auxiliary tool 9, are aligned parallel to the side walls of the receiving part 151, 161, as can be seen by way of example in Figure 8. In the preferred embodiment according to Figures 4 to 14, these side edges of the actuating tongue 91 come into contact with side edges of the latch element 170, which serves to lock the adjusting device 100, i.e. the first lever 150 and the second lever 160.

[0045] The latch element 170 is inserted into the receiving portion 151 , 161 of the first lever 150 or the second lever 160 . To adjust the carrier 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 an auxiliary tool.

[0046] The pivot pin 131 of the first slider 130 projects into a pin receiver 153 in the region of the end of the first lever 150 remote from the receiver 151 and serves here as the pivot point of the first lever 150 . A pivot pin 114 molded on the base plate 110 serves as a pivot point for the second lever 160 .

[0047] To adjust the carrier plate 120 in the first adjustment direction x, the driver web 121 protrudes from the carrier plate 120 through the elongated hole 132 of the first slider 130 extending in the first adjustment direction x, and into the elongated hole 152 of the first lever 150 and the elongated hole 145 of the second slider 140 extending in the second adjustment direction y.

[0048] In the assembled state, the side edges of this driver web 121 are in contact with the longitudinal side edges of the slot 152 of the first lever 150, so that by pivoting the first lever 150 by a pivoting movement, the slot 152 moves in the first adjustment direction x, thereby transporting the driver web 121 and thus the carrier plate 120 in the first adjustment direction x.

[0049] As can be seen from FIG. 4, the driver web 141 protrudes into an elongated hole 162 of a second lever 160 that extends from the second slider 140 in the first positioning direction x. Therefore, when the second lever 160 is pivoted via the driver web 141, its side edge abuts against the longitudinal side edge of the slot 162 of the first lever 150, causing the second slider 140 to also move in the second positioning direction y (relative to the base plate 110).

[0050] A latching element 170 is provided to lock the adjustment device 100 in a desired position. The respective latch elements 170 are fixed in the region of the receiving portions 151, 161 of the first and second levers 150, 160, respectively.

[0051] To lock the levers 150, 160 in position, latch teeth 113, 133 are formed on the first slider 130 and in the area of ​​the base plate 110 where the receiving portion 161 of the second lever 160 for inserting the auxiliary tool 9 is positioned, and these teeth can engage with latch teeth of the latch strip 171 of the latch element 170. When the auxiliary tool 9 is inserted into the receiving portion 151 , 161 of the first or second lever 150 , 160 , the latch strip 171 disengages from the latch teeth 113 , 133 , the base plate 110 or the first slider 130 .

[0052] The actuation tongue 91 of the auxiliary tool 9 pushes the latch strip 171 of the respective latch element 170 away from the face of the latch tooth 113, 133 in the position inserted into the receiving part 151, 161. Figure 5 shows an example of an adjustment device 100 attached to the first body 2, where one of the two auxiliary tools 9 is inserted into one of the receiving portions 151, 161 of the first or second lever 150, 160.

[0053] The position of the guide bolt 180 in the slot 122 of the carrier plate 120 indicates that the carrier plate 120 is in a neutral position in the first positioning direction x, which can also be recognized by the center position of the auxiliary tool 9 . Instead of the auxiliary tool 9 being able to be inserted as required into receiving parts 151, 161 provided for this purpose, the actuating tongue 91 of the auxiliary tool 9 is, in an alternative embodiment variant, permanently fixed to the receiving parts 151, 161, as shown in Figures 5a and 5b.

[0054] In this embodiment, the auxiliary tool 9 is configured with a handle 92 that can be folded relative to the actuation tongue 91. For this purpose, the handle 92 is connected via a folding mechanism 93 to the actuation tongue 91 that is permanently housed in the respective receiving part 151, 161.

[0055] This allows the handle 92 to be folded into the slot 5 when not in use, as shown in Figure 5b. To operate the auxiliary tool 9, the second body can preferably be pushed open or rotated slightly relative to the first body 2 to access the handle 92.

[0056] Alternatively, it is conceivable to provide an additional folding mechanism with a push-open mechanism, and if necessary, the push-open mechanism can be triggered by pushing the side edge of the handle 92 close to the outer edge of the first body 2 further into the slot 5, thereby opening the handle 92 from the position shown in Figure 5b to the position shown in Figure 5a, and adjusting the first fitting portion 41.

[0057] FIG. 8 shows an example of a position to which the carrier plate 120 is adjusted by pivoting the second lever 160, which is accompanied by a displacement of the carrier plate 120 in the second positioning direction y. 9 to 14 show further different adjustment positions of the carrier plate 120 relative to the base plate 110 and their movement by manipulating the corresponding levers 150, 160.

[0058] 15 to 25 show another preferred embodiment of the adjustment device according to the present invention. As shown in particular in the exploded views of Figures 17 and 18, this embodiment of the adjustment device 200 also has a base plate 210 that can be fixed to the first body 2 and a carrier plate 220 that can be fixed to the second body 3.

[0059] In contrast to the adjustment device 100 shown in Figures 1 to 14, this adjustment device 200 has an intermediate plate 230 arranged between the base plate 210 and the carrier plate 220 to allow displacement in the two adjustment directions x, y.

[0060] Thus, on the one hand, the intermediate plate 230 allows adjustment of the carrier plate 220 relative to the intermediate plate 230, and on the other hand, allows adjustment of the intermediate plate 230 relative to the base plate 210, with the carrier plate 220 being moved together with the intermediate plate 230.

[0061] As can be further seen from Figures 15, 17 and 18, the adjustment device 200 has two base holders 240, 250 attached to a base plate 210, each of which has a slide element 260 received in a slide element receiving portion 241 so as to be displaceable in one of the adjustment directions x, y.

[0062] Thereby, the carrier plate 220 is held on the intermediate plate 230 so as to be displaceable in the first positioning direction x, while the intermediate plate 230 is held on the base plate 210 so as to be displaceable in the second positioning direction y. As shown in Figures 15 and 17, the elongated holes 221 extending in the first adjustment direction x are provided to mount the carrier plate 220 on the intermediate plate 230 so as to be displaceable in the first adjustment direction x, and receive bolts 201 with mushroom-shaped heads fastened to the intermediate plate 230.

[0063] Therefore, the base holders 240, 250 have bolts 246, 256 on the side facing the intermediate plate 230, which are received in the elongated holes 231 of the intermediate plate 230 extending in the second positioning direction y and do not prevent the intermediate plate from shifting in the second positioning direction relative to the base plate 210. Similar to the lever 150, 160 or the latch element 170 of the first embodiment, the sliding element 260 has a receiving portion 261 for inserting the auxiliary tool 9.

[0064] The slide element 260 received in the first base holder 240 is fixedly coupled to the intermediate plate 230, and the slide element 260 received in the second base holder 250 is fixedly coupled to the carrier plate 220. This makes it possible to displace the intermediate plate 230 or the carrier plate 220 by moving the respective slide element 260 .

[0065] To fix the slide element 260 to the intermediate plate 230 or the carrier plate 220, the slide element 260 has at least one web 262, which is aligned perpendicular to the intended adjustment direction x, y and which protrudes or protrudes securely into the web receiving portions 222, 232 of the intermediate plate 230 or the carrier plate 220; in the example embodiment, two webs are shown. The web receiving portions 222, 232 are formed as slot-shaped recesses in the carrier plate 220 or the intermediate plate 230.

[0066] As shown in FIG. 17, the web receiving portion 232 of the intermediate plate 230 is preferably integrally formed in an area 233 of the intermediate plate 230 that is slightly raised relative to the remaining surface of the intermediate plate 230, and in the assembled state is located in a recess 244 of the first base holder 240 and is guided in the second positioning direction y by a side edge 245 of the recess 244. Additionally, the slide element 260 preferably has a clamping web 263 that projects into a clamping device 270 that is received in each base holder 240 .

[0067] The clamping device 270 has two ball carriers 271 each holding a ball 272. However, depending on the configuration, more than one ball 272 may be disposed within one ball carrier 271. The ball carriers 271, each having a ball 272 fixed thereto, are held displaceably in the respective positioning directions x, y within respective recesses 242, 252 of base holders 240, 250 shown by way of example in Figure 18 using a first base holder 240.

[0068] One of the base holders 240, 250, in this case base holder 250, is preferably formed in two parts, a first part being held on the base plate 210 into which a second part 255 can be inserted, and a recess 252 being formed in the second part 255. The balls 272 are each mounted within the conical portions 243, 253 of the respective recesses 242, 252 and can be moved by sliding the ball carrier 271 from a spring-loaded clamped position that clamps the clamping web 263 of the respective slide element 260 to an unlocked position that does not clamp the clamping web 263 of the respective slide element 260.

[0069] As can be seen particularly in Figures 18 and 21b, 22b, 23b, 24b and 25b, the ball carriers 271 are moved away from each other in the longitudinal extension of the clamping webs 263 to release the clamping webs 263.

[0070] The recesses 242 , 252 of the base holders 240 , 250 are formed in pairs and mirror-symmetrically with respect to a central imaginary mirror axis aligned perpendicular to the longitudinal direction of the clamp web 263 .

[0071] This arrangement of the recesses 242, 252 has the advantage that the ball carrier 271 can be moved from the clamped position to the released position by inserting the auxiliary tool 9 into the receiving portion 261 of the slide element 260, and can be spring loaded and returned from the released position to the clamped position after removing the auxiliary tool 9 from the receiving portion 261 of the slide element 260.

[0072] As shown by way of example in FIG. 18, a spring element 273, in particular in the form of a compression spring, is provided for spring loading and is housed in a receiving section provided for this purpose in the ball carrier 271, bearing on the one hand against the inner wall of the receiving section of the ball carrier 271 and on the other hand against the rear wall of the respective recess 242, 252 extending perpendicular to the actuation directions x, y, so that the ball carrier 271 is always pressed into the clamping position by the force of the spring element 273.

[0073] In alternative embodiments, it is contemplated that the ball carrier 271 having the ball 272 housed therein may be replaced by other clamp bodies having corresponding clamp body carriers. Cylinders, rollers, sliders or wedges held in appropriately configured clamping element carriers are particularly conceivable as clamping elements. FIG. 19 a shows a top view from below of the adjusting device 200 , with one of the two auxiliary tools 9 inserted into the receptacle 261 of one of the sliding elements 260 .

[0074] The auxiliary tool 9 is here positioned in a neutral position within the slide element 260 which is connected to the intermediate plate 230, so that by pivoting the auxiliary tool 9, a displacement of the intermediate plate and of the carrier plate 220 in the second positioning direction y is effected, as can be seen in FIG. 19b.

[0075] In a corresponding manner, FIG. 19c shows the adjustment of the carrier plate 220 only in the adjustment direction x, and FIG. 19d shows the adjustment of the carrier plate 220 in the adjustment direction x and additionally the adjustment of the carrier plate 220 together with the intermediate plate 230 in the adjustment direction y.

[0076] As further shown in Figures 20a and 20b, the ball carrier 271 of the clamping device 270, in addition to holding the clamping ball 272, also serves as a stop or pivot point for the auxiliary tool 9, which is used as a lever, allowing the carrier plate 220 to be adjusted with as little force as possible.

[0077] For this purpose, the ball carrier 271 has an insertion chamfer 274 to facilitate the insertion of the actuation tongue 91 of the auxiliary tool 9 and the pushing apart of the paired clamping devices 270 .

[0078] The insertion chamfer 274 adjoins a pivot point area 275 of approximately circular cross-sectional shape, against which the side edges of the actuating tongue 91 abut and which form a pivot point when the auxiliary tool 9 pivots in a plane spanning the actuating directions x, y, thereby causing displacement of the respective slide element 260 and thus the intermediate plate 230 and / or the carrier plate 220.

[0079] 21a, 21b to 25a, 25b show the sliding action due to the displacement of the ball carrier 271 and the release of the sliding element 260 with the displacement of the ball 272 held by the ball carrier 271. FIG.

[0080] Figure 21a shows the sliding element 260 in a neutral position before displacement of the intermediate plate in or against the adjustment direction y, and the clamping device 270 consisting of two ball carriers 271 in a clamping position, in which the clamping web 263 of the sliding element 260 is clamped by the balls 272, thus preventing unintentional or accidental displacement in or against the adjustment direction y.

[0081] FIG. 21b shows a partial cross-sectional view showing four balls 272 that clamp the clamping web 263, which are advanced by spring elements 273 into the conical portions 243, 253 of the respective recesses 242, 252 to the extent that they clamp the clamping web 263.

[0082] 22a and 22b show the auxiliary tool 9 inserted into the receiving part 261 of the sliding element 260 in the neutral position. As can be clearly seen here, the ball carrier 271 is moved to the release position by the insertion of the auxiliary tool 9.

[0083] As can be seen in FIG. 22b, the ball 272 is moved to a wider area of ​​the conical portion 243 so that the clamping web 263 is no longer clamped by the ball 272 and does not interfere with the intended sliding movement of the sliding element 260.

[0084] 23a and 23b show the slide element 260 displaced in the direction opposite to the actuation direction y. As can be seen in FIG. 23 b , the ball 272 is still in the released position where it does not clamp the clamping web 263 . 24a and 24b show representations corresponding to FIGS. 23a and 23b with the sliding element 260 displaced in the actuation direction y. 25a and 25b show the sliding element 260 displaced in the adjustment direction y after the auxiliary tool 9 has been removed from the receiving part 261 of the sliding element 260. FIG.

[0085] As can be seen in particular in FIG. 25 b, by removing the auxiliary tool 9 the ball 272 together with the ball carrier 271 has been pushed back into the clamping position where the clamping web 263 is held in its current position by the spring force of the spring element 273 . 26-31 show another alternative embodiment for locking the sliding element 260'.

[0086] In this embodiment, the head 262' of the slide element 260' protrudes into the recess 231' of the intermediate plate 230' with a width adapted to the intended positioning directions x, y, and the parallel side edges 263' of the head 262' of the slide element 260' abut against the side edges of the intermediate plate 230. Therefore, the carrier plate 220 is also configured with a web or head receiving portion instead of two web mounting portions (not shown here).

[0087] The slide element 260' is here clamped by a clamp element 280, as shown by way of example in FIG. The clamping element 280 has a base body 281 that is located in a clamping element receiving portion 241' of a base holder 240' extending in the adjustment directions x, y, from which extend two curved arms 282 that have clamping sleeves 283 formed at their ends, which, in the mounted state, are arranged on either side of a head 262' of the slide element 260' and protrude into grooves 242' that are parallel to the clamping element receiving portion 241' of the base holder 240'.

[0088] In the clamped position, as shown by way of example in FIG. 28, the clamp sleeve 283 is located between the shoulder 266' of the slide element 260' and the conical clamping surface 232' on the outside of the recess 231' of the intermediate plate 230', whereby the slide element 260' and the clamp sleeve 283 prevent the intermediate plate 230 from being displaced in the adjustment directions x and y.

[0089] To release this clamp, the slide element 260 is pressed further into the recess of the intermediate plate 230' by inserting the auxiliary tool 9 in a direction perpendicular to the intended positioning direction x, y, as shown in Figure 29.

[0090] As a result, the clamping sleeve 283 is pushed outward from the shoulder 266' of the slide element 260' via the inclined region 264' and thus out of the clamping region between the side edge of the groove 242' of the base holder 240' and the conical clamping surface 232' that clamps the clamping sleeve 283 against the widened region, in which region the clamping sleeve 283 is pressed through the widened region between the side edge of the groove 242' of the base holder 240' and the conical clamping surface 232' that clamps the clamping sleeve 283, thereby releasing the clamping of the intermediate plate 230' and the slide element 260'.

[0091] FIG. 29 already shows the slide element 260' adjusted in the positioning direction y. Figure 30 shows the slide element 260' displaced in the opposite direction of the adjustment direction y, and Figure 31 shows the slide element displaced according to Figure 30 with the auxiliary tool removed, and the slide element 260' is pushed back into the clamping position by the spring force of the spring arm 282 of the clamping element 280. The pivot point of the auxiliary tool 9 is now formed by the inner edges of the base holder 240' which also come together. [Explanation of symbols]
