    Description: The present invention relates to a multi-part fitting according to the preamble of claims 1, 1 and 9. Such fittings are used primarily, but not exclusively, for the invisible connection of, for example, parts of a piece of furniture and are inter alia from DE 20 2016 102 175 U1 and DE 20 2016 102 176 U1 known.
    Such fittings preferably consist of elastically deformable plastic which has comparatively good sliding properties.
    The connection can be made between Holzeilen. A more common (but not the only) case concerns the joining of two particleboard in a T-joint, where the chipboard has a hard surface coating except for the edges, so that in the T-joint, a rough chipboard strikes a surface coating , The connection is made in such a way that the necessary holes are drilled in the parts to be connected, the fittings are inserted into the holes in a pre-assembly position, for example according to DE'175 U1 and DE Ί76 U1, and the parts to be connected are driven together, often by one Beat so that the fittings are pushed together in the mounting position and lock in this, which fixes the two parts to be joined against each other.
    Such fittings have the disadvantage that the connection often does not succeed gap-free and also the capacity is not sufficient to accommodate even larger loads.
    Accordingly, it is the object of the present invention to provide a multi-part fitting, can be fixed without gaps with the parts to be joined and / or the connection is highly resilient.
    To achieve this object, a fitting according to the invention has the characterizing features of one of claims 1, 7 or 9.
    The fact that the expansion element is compressed during the pushing together of the fitting in the feed direction results in the moment when the effect of the parts to be joined together has lessened shortly before the collision of the parts, a supporting effect for the complete Moving together the fitting in its mounting position, with the result that the parts to be joined completely abut each other after the assembly process or no longer spring back from each other something. Next results from the locking via a locking step with a locking stop a fixation of the fitting in the mounting position, which is higher loadable due to the achievable step height than the known, relatively finely articulated locking latch, as these often under the prevailing forces during assembly forces also plastically deformed and so is not highly resilient.
    Characterized in that in the case of a fitting with U-bolts, the locking takes place in the mounting position over the length of the legs, a locking connection is available, which can be formed over a large length with robust teeth and is correspondingly high load capacity.
    Characterized in that in the case of a fitting with two identical plug-in parts, each with a flächenigen base portion and a subsequent Flächigen tongue, the latching connection is formed along the side edges of the tongue, also in this design, the advantages of the locking connection with robust teeth on a large Long.
    The invention will be described below with reference to the figures a little closer.

    Schematically, in the manner of a line drawing, a multi-part fitting 1 * according to the prior art, with two identical U-shaped brackets 1 and 1diezugewendet in 90 ° gegeneinanderverdrehter location. The brackets have a web 2, 2 'and two legs 3, 4 and 3', 4 ', which extend away from the web 2, 2' and next to each other. From the bracket 1 'only the leg 3' can be seen, the leg 4 'is covered by the leg 3'. Also concealed is the web 2 ', which is indicated by a dashed line. The legs 3, 4 and 3 ', 4' are spread apart from one another in the direction of the arrows 5, 6 (leg 1). The spreading direction of the legs 3 ', 4' runs perpendicular to the plane of the drawing. Depth stops 7, 8 and 7 ', 8' at a first portion 9,10 and 9 ', 10' (the portion 10 'is hidden) of the respective leg 3,4 or 3', 4 'prevent that at mounting a bracket 1,1 'can be pushed too far in the associated hole him (see Fig. 2a to 2c).
    Outwardly directed anchoring claws 11,12 and 11 ', 12' (the anchoring claws 12 'are hidden) at a second portion 13, 14 and 13', 14 'of the legs 3, 4 and 3'4' serve to anchor the respective bracket 1,1 'in a borehole. Inwardly directed Ftastelemente 15,16 or 15 ', 16' serve the mutual fixation of the strap 1,1 'together, when they are pushed together in the assembled position (see Fig. 2c), by opposing, outwardly directed locking elements 17th ', 18' and 17, 18 of the respective web 2'2 cooperate (again, the locking elements 15 ', 16' and 17, or 17 ', 18' covered).
    From the position shown in Fig. 1a, the bracket can be brought 1,1 'in a pre-assembly by the bracket 1 in the direction of the arrow 19 and the bracket 1' in the direction of the arrow 20 is moved.
    Fig. 1b shows the fitting 1 * with the straps 1,1 'in preassembly position, i. in a position in which it can be used in the boreholes 25,26 of two workpieces, such as chipboard panels 27, 28 with surfaces 29, 30, to connect these bestimmungsgemâss seamless, resilient and invisible with each other. The brackets 1, 1 'are pushed through one another according to the direction of the arrows 19, 20 of FIG. 1 a, so that now, in contrast to FIG. 1 a, the bracket 1 on the right and the bracket 1 in FIG 'left lies.
    Fig. 2a shows the fitting 1 * still in pre-assembly, but with inserted in the holes 25,26 brackets 1,1 '. The depth stops 7, 8 of the bracket 1 rest on the surface 30, the depth stops 7 ', 8' (the depth stop 8 'is concealed) on the surface 29, so that the bracket 1 does not extend further into the plate 28 assigned to it Bracket 1 'can not penetrate further into its associated plate 27. "Assigned" means that the bracket 1.1 'keeps its position unchanged relative to the respective plate during assembly and under later loading.
    From the pre-assembly position, the parts to be joined, i. here the chipboard panels 27, 28 are pushed against each other in the direction of the arrows 31,32 until the fitting 1 * fixed them together without joints.
    Moves the chipboard plate 27 to the right, in the direction of arrow 31, the position of the bracket 1 remains against the chipboard plate 28 as mentioned unchanged, as the bracket 1 with the depth stops 7.8 on the surface 30 of the chipboard 28 is supported. As a result, the chipboard plate 27 moves from the left, in the direction of the arrow 31, over the bracket 1, which thus, with the web 2 in front, dips into the borehole 25. In the same way, the bracket 1 'remains supported by its depth stops 7', 8 'on the surface 29, so that it dips into the borehole 26 with the web 2' ahead.
    Fig. 2b shows the fitting 1 * during the collapse of the parts to be joined 27, 28. The bracket 1 is pressed into the borehole 25, the wall of the borehole 25 leads to the first section 9, 10 of his legs 3, 4th (Figure 1a) (in the direction of arrow 31). It should be mentioned again that the bow 1 remains in unchanged position with respect to the chipboard plate 28 thanks to the depth stops 7, 8.
    The bracket 1 ', thanks to the depth stops 7', 8 'in an unchanged position with respect to the chipboard plate 27, leads with the web 2' ahead in the borehole 26, its feed direction corresponds to the direction of the arrow 31. In this case, the bridge beat. 2 'on the second section 13, 14 of the legs 3, 4 and pushes them apart, ie spreads this, with which the anchoring claws 11, 12 are pressed against the wall of the borehole 26. Once the anchoring claws 11, 12 penetrate into the wall of the borehole 26, the bracket 1 anchored on this in the chipboard 28. Also, of course, the web 2 spreads the second portions 13 ', 14' (the portion 14 'is hidden) of the bracket 1 ', so that the bracket 1' via its anchoring claws 11 ', 12' anchored to the wall of the borehole 25.
    Thus, the components of the fitting 1 * in a feed direction from a pre-assembly position (Fig. 2a) in an assembly position (Fig. 2c) collapsible. If during the assembly process, the chipboard plate 28 resting and the chipboard plate 27 is assumed to be moved, the bracket 1 is stationary, while the bracket 1 'moves in a direction of arrow 31 corresponding feed direction. Conversely, when the chipboard 27 rests, then the bracket 1 moves in a direction of arrow 32 corresponding feed direction. If both plates 27, 28 move toward one another, one of the stirrups 1, 1 'is stationary with respect to each of the plates, and the other stirrup 11 moves in the corresponding advancing direction relative to the stationary stirrup 1, 1'. The feed direction can thus be seen starting from one of its plate 27, 28 associated bracket 1 ', 1 as a direction with which the other part of the fitting 1 *, here the bracket 1,1' moves when moving into the mounting position.
    Fig. 2c shows the fitting 1 * when the chipboard panels 27, 28 have moved together. The wall of the borehole 25 has elastically deformed the first sections 9, 10 of the legs 3, 4 (Fig. 1a) of the bracket 1, i. compressed, so that the depth stops 7, 8, the surface 30 of the plate 28 have released. Thanks to the anchoring claws 11, 12, however, the bracket 1 is firmly seated in the plate 28. Likewise for the bracket 1 ', which sits firmly in the plate 27 thanks to the anchoring claws 11, 12', since its depth stops 7 ', 8' pass through the wall of the borehole 26 has been compressed. Thereby, i. by the elastic deformation of the legs 3, 4 and 3 ', 4' during the assembly process, the seamless connection of the parts 27, 28 can be realized.
    Since each of the bracket 1, 1 'is fixed in «his» plate 28,27, the plates 27, 28 can only be separated from each other, if the strap 1,1' contrary to the feed direction would diverge again. This is achieved by the locking of the locking elements 15,16 of the legs 3, 4 of the bracket 1 with the locking elements 17 ', 18' of the web 2 'of the bracket 1' and by the locking of the locking elements 15 ', 16' of the legs 3 ', 4 'with the locking elements 17, 18 of the web 2 of the bracket 1 prevented.
    Fig. 2d shows a section in the region of the plate 28 in a plane parallel to the representation of Fig. 2c, which passes through the web 2 '. The second sections 13, 14 of the legs 3, 4 of the bracket 1 (FIG. 1 a) and the web 2 'of the bracket 1' (FIG. 1 a) can be seen.
    The latching of the bracket 1,1 'takes place here formed as Rastzâhne locking elements 15,16 on the second section 13, 14 of the legs 3, 4 arranged on the web 2', as opposed Rastzâhne formed locking elements 17Ί8 '. Equally formed is of course not shown in Fig. 2d latching of the bracket 1, 1 'on the web. 2
    Fig. 3a shows a possible faulty mounting position of the fitting 1 *, as it can occur especially in a soft surface 30, such as the front side of a chipboard. Common is a combination of soft surface 30 with a hard surface 35, which may consist of a melanin coating for a chipboard.
    It is seen that the depth stops 7, 8 of the bracket 1 are sunk into the surface 30, so that the second portions 13, 14 of the legs 3, 4 of the bracket 1 (FIG. 1 a) protrude too far into the plate 28 , This occurs, for example, when the web 2 of the bracket 1, which in the feed direction according to the arrow 32 on the second portions 13 ', 14' of the bracket 1 'zuluft, this due to the back pressure by abutting the wall of the borehole 25 anchoring claws H ', 12' is no longer able to spread apart as intended, and then runs up on it and is therefore severely slowed down. The drive for the feed in the direction of arrow 32, the plate 28 provides over its surface 30, which abuts the depth stops 7, 8 and pushes them. If the braking effect is too great or the surface 30 too soft, the depth stops sink into the surface 30, with the result that the advancement of the clip 1 prematurely comes to a standstill. The stirrups 1, 1 'of the fitting 1 * are thus not completely moved together, the second portions 13, 14 or 13', 14 'are not sufficiently spread by the webs 2' or 2. The anchoring claws 11,12 and 11 ', 12' are thus insufficiently pressed into the walls of the holes 25,26, so anchored in these, so that the strength of the connection is disadvantageously reduced.
    The strong braking of the webs 2, 2 'can also have the consequence that the (necessarily) elastically deformable legs 3, 4 or 3', 4 'in addition, beyond the intended deformation bend out, i. deflect. Is now the assembly process completed by the collapse of the plates 27,28, feathers the legs 3, 4 and 3 ', 4' back again, creating a gap between the plates 27, 28: the connection is disadvantageously loose.
    Unwanted sinking into the surface or unwanted suspension of the legs can occur independently of one another or together, depending on the material of the plates to be joined and that of the fitting, in conjunction with concrete the geometry of the fitting.
    Fig. 3b shows the same section as Fig. 2d, but then, when the strap are 1,1 'not completely folded together according to Fig. 3a. It is seen that then the locking is only with a part of the locking elements in engagement, so that again the load capacity of the assembled fitting 1 * is disadvantageously reduced.
    The fitting 1 * shown in FIGS. 1 a to b is collectively designed in several parts and provided for anchoring in a hole, the components (in this case the brackets 1, 1 ') being in a feed direction (direction according to arrow 31 or arrow 32) from a pre-assembly position (Fig. 2a) in an assembly position (Fig. 2c and 3a) are collapsible. The fitting 1 * has an anchoring arrangement for anchoring the fitting to a perforated wall (here the legs 3, 4 or 3 ', 4' of the bracket 1,1 '), with opposing, outwardly directed anchoring claws 11, 12 and 11 ', 12', as well as depth stops 7, 8 and 7 ', 8'. Furthermore, the fitting 1 * has a locking arrangement for spreading the anchoring arrangement in the region of the anchoring claws 11, 12 or 1112 ', with a spreading element formed in FIGS. 1 to 3b as a web 2, 2'.
    Fig. 4a shows a schematic view of a erfindras formed according to the invention bracket 40 for a multi-part fitting, which in the embodiment shown has two identically designed bracket according to the bracket 40 and according to Figs. 2a to 2c inserted into a pre-assembly and then into a Assembly position can be pushed together.
    The bracket 40 has a web 41 and extending from this next to each other, expandable legs 42, 43, each with a depth stop 44, 45 having first portion 46, 47 and an outwardly projecting anchoring claws 48, 49 having the second section 50, 51. The first section 46, 47 connects to the web 41, the second section 50, 51 to the first section 46, 47. The locking claws 48, 49 are arranged at the ends of the legs 42, 43.
    According to the invention in the second sections 50, 51, on the inside, in each case one in the section 50, 51 einspringender locking stop 52, 53 is provided, which forms a shoulder, on which a spreading counter-surface 54, 55 connects , which in turn is inclined in the feed direction to the outside of the second section 50, 51. Starting from the bracket 40, which is to be fixed in a workpiece omitted for the relief of the figure for assembly (see the description of FIGS. 2a to 2c), the feed of an identical bracket takes place in the direction of the arrow 56.
    Thus, the spreading counter surface 54, 55 starting from the locking stop 52, 53 under the anchoring claws 48, 49 away from the web 41, against the free end of the second portions 50, 51 out, and at the same time schräg outwards, against the anchoring claws 48, 49 too. Fig. 4b shows a section through the bracket 40 in a plane perpendicular to the figure, passing through the dashed line level with a view of the second leg 43 corresponding to the direction of view shown by the arrows AA.
    The web 41 has on its the first portion 47 (and thus also the first portion 46) facing the inner side 57 each have an outwardly jumping locking step 58, 59 forming edge.
    At the locking levels 58, 59 connect as Spreizflche 60, 61 formed side surfaces of the web 41, which preferably extend to the inner side 57 opposite outer side 62. The spreading surfaces 60, 61 are inclined, such that the thickness of the web increases from the inner side 57 towards its outer side 62. The web has a rhomboid cross-section in the embodiment shown. It follows that the expansion surface preferably extends as far as the end region of the spreader element designed as web 41 'and, starting from the locking step, is inclined away from the spreader element in the feed direction.
    5a to 5c show a sequence of sectional drawings through a portion of a fitting according to the invention, which has two identically constructed brackets according to the bracket 40, during the collapse of the brackets from the pre-assembly position into the assembly position. The position of the cuts corresponds to those of FIGS. 2d and 3b.
    Figure 5a shows the second portions 50, 51 of the bracket 40 (Figure 4a) inserted in the borehole 26 of a plate 28 (see, e.g., Figure 2b). A web 41 'of a similar to the relief of the figure, identical bracket pushes in the feed direction according to the arrow 31 through the hole in the direction of the anchoring claws 48, 49, spreads the legs 42, 43, in particular their second sections 50, 51st Due to the counterpressure of the spread legs, the rhombic cross section of the web 41 (Figure 4b) is usually somewhat flattened, here complete, so that the cross section of the web 41 has now become approximately rectangular due to the pressure. The Spreizflachen 60 ", 61 'diverge less, here only little or not more.
    The end portions of the second portions 50, 51 tilt inwardly because the second portions are not stiff enough to force the anchoring claws 48, 49 into the wall of the bore 26. The locking steps 58 ', 59' approach the locking abutments 52, 53.
    Fig. 5b shows the assembly process at the moment in which the web 41 'the Verriegelungsanschläge 52, 53 überfâhrt. Since these form a step which recedes in the second sections, the leading end of the web 41 'can again expand somewhat towards its original rhombic shape. In addition, the web 41 'now presses directly onto the anchoring claws 48, 49, which begin to dig in the wall of the borehole 26. Still, the tip of the free end of the second sections 50, 51 is slightly bent towards the inside. However, since the spreading counter surfaces 54, 55 are outwardly inclined in the undeformed state of the second portion 50, 51, in the bent state, there will still be at least about a straight line, i.e., an angle. parallel alignment of the areas 65, 66 of the spreading counter surfaces located in front of the noses 63 ', 64'. This has the advantage that the further advancement of the web 41 'is not slowed down by an abutment against the spreading counter surfaces 54, 55.
    With the further advancement of the web 41 'in the direction of the arrow 31, the area of the web 41' which has reached the locking projections 52, 53 continues to expand, with which the anchoring claws 48, 49 are more and more inserted into the wall of the web Drill hole 26 are pressed, although the areas 65,66 of the spreader surfaces horizontally inclined at maximum only negligible downwards.
    Thus, it is mainly the by the expansion of the web 41 'outwardly inclined portions of the expansion surfaces 60', 61 ', which press the anchoring claws 48, 49 in the wall of the borehole 26.
    Fig. 5c shows the web 41 'in the same position between the second sections 50, 51 of the legs 42, 43 as Fig. 5b. Shown are the reaction forces 67, 68 of the inclined portions of the expansion opposing surfaces 54, 55 (FIG. 5b) and the reaction forces 69, 70 of the locking abutments 52, 53 on the web 41 ', i.e., the reaction forces. These reaction forces 67 to 70 are inclined obliquely against the free end portions of the second sections 50, 51, have a component in the direction of the arrow 31 and therefore drive the web 41 in the advancing direction, as indicated by the dotted arrow 71. In other words, it is such that the spreading counter surfaces press the web 41 ', as soon as it is in the region of the anchoring claws 48, 49, in the feed direction that it is facilitated in its end position according to the Fig. 5d passes.
    In this way, it is possible to prevent the stirrup having the bar 41 'from sinking into the surface of the plate assigned to it, because the bar 41' is less relevantly affected by the supporting effect of the pinch in the feed direction (see the description of FIG 3a). In addition, it is so that the legs of the web 41 'having bracket must transmit less feed force, so less or no longer spring when the web 41' jumped at the end of its advance through the pinch to some extent in its end position shown in Fig. 5d is.
    Fig. 5d shows the web 41 'in the mounting position between the two second sections 50, 51 of the legs 42, 43 of the bracket 40 (Fig. 4a). The Spreizflächen 60 ', 61' are fully against the expansion counter surfaces 54, 55 and press the anchoring claws 48, 49 in the wall of the borehole 26. The locking stages 58 ', 59' strike in the opposite direction to the feed direction, namely in Direction of the arrow 32 at the Verriegelungsanschlägen 52, 53 and prevent movement of the web 41 'against the feed direction. The fitting with the bracket 40 and the web 41 'belonging to the second bracket is locked in the mounting position, the lock is highly resilient, the locking stages 58', 59 'together with the inclined Spreizflche form a stronger catch than the necessary -wise small locking elements according to the prior art is the case. Such locking elements can also be plastically deformed during the feed, when they are scraping past each other, which in turn reduces their effectiveness.
    Of course, the bracket 40 has a web 41 'equal to the web, while the legs of the web 41' having bracket are formed the same as those of the bracket 40th
    In summary, according to the invention a multipiece fitting for anchoring in a hole, the-sen components (bracket 40) in a feed direction from a pre-assembly in a mounting position are pushed together, with a Tiefenanschlåge (44, 45) and an opposite one another , to the outside directed Ver-anchoring claws (48, 49) having, expandable anchoring arrangement (here the legs 42, 43) for anchoring the fitting to a perforated wall, and with a spreading element (here the web 41) for the anchoring arrangement having locking arrangement for spreading the anchoring arrangement in the region of the anchoring claws (48, 49), wherein the locking arrangement on the inside of the anchoring arrangement in the region of the anchoring claws (48, 49) provided, einspringende Verriegelungsanschläge (52, 53) and from each locking stop starting out a spreading Counter-surface (54, 55), which in the feed direction for On the outside of the anchoring arrangement is inclined, and further the expansion element has an outwardly jumping locking step (58, 59) and an outgoing therefrom, extending to an end portion of the expansion Spreizflche 60,61), starting from the locking step (58, 59 ) is inclined away in the feed direction of the expansion element, such that in operation when pushing together the fitting the Spreizflche is pushed in the feed direction over the locking stop, while the expansion element is not hindered by the spreading counterface in the feed direction substantially, but is squeezed in the feed direction and in Mounting position, the locking step (58, 59) on the locking stop (52, 53) is applied, so that the spreader is blocked against the feed direction.
    A fitting according to the invention achieves a load capacity of approximately 350 N to 400 N in the case of 8 mm boreholes in connected parts, whereas a conventional fitting according to FIGS. 1a to 3b has a load capacity of approximately 150 N to 200 N reached.
    For the geometry of the fitting according to the invention and the choice of material, no general rule can be given, in the concrete case these parameters are to be determined by a person skilled in the art. For example, the material for fitting may be selected depending on the hardness of the parts to be joined and also on the diameter of the drilled holes.
    A further embodiment according to the invention is shown in FIGS. 6a to 6d. The bracket 150 shown in Fig. 6a corresponds to the bracket 40 of Fig. 4a, with the exception that the Verriegelungsanschläge 52, 53 of the bracket 40 omitted. Thus, the spreading counter surfaces 151, 152 of the bracket 150 extending from the inside of the second portions 50, 51 of the legs 42, 43, starting in the direction of the web 41 away against the anchoring claws 48, 49, thus forming an outwardly beveled end for the second sections 50, 51.
    Accordingly, Fig. 6b shows a section through the bracket 150, which corresponds to the section through the bracket 40 (Fig. 4a) in Fig. 4b. The Spreizflche 153,154 here are designed to be slightly longer, so that the inner side 155 of the web 156 ausfllls less high, corresponding to the edges 86,87 form the transition from the Spreizflche 153, 154 to the inner side 155 without them a locking step in the art the locking stage 58, 59 (Fig. 4b) form.
