Description

The present invention relates to a sliding door fitting having two profiles which are arranged on the end face of one another at a joint and are connected to one another via a profile connector, wherein the profiles are arranged at least partially in alignment and have a receptacle for inserting a portion of the profile connector, wherein the profile connector can be fixed to the receptacle in a clamping manner by pivoting in.DE 75 28 036 U discloses the connection of a plurality of profile sections of a guide track profile, in which receiving grooves for butt connectors are provided. The impact connectors, which are trapezoidal in cross section, can thus be inserted into the receiving grooves, so that the profile sections can then be mounted as a unit on a piece of furniture cabinet. A disadvantage of such a butt connector is that it can only be mounted before the profile sections are mounted, which is difficult especially in the case of longer guide rails on cabinets. In addition, when the push connectors are inserted, a burr can be pushed on, which then prevents the profile sections from bearing against one another in a form-fitting manner.EP 572 936 A1 discloses a rail formed from a plurality of profile pieces, which are clamped to one another via coupling pieces. For this purpose, a coupling piece is inserted into a groove on the profile pieces, which coupling piece is then clamped by means of a self-tapping screw. In the case of such a bracing of the profile sections, there is the problem that the screws can be tightened too weakly or too strongly and then either too low holding forces are present or a deformation of the profile sections occurs. Despite the rather complicated mounting, problems during the bracing of the profile sections cannot be avoided.EP 1 705 372 A2 discloses a rail arrangement having two profile sections which are stabilized via a cylindrical connector. The cylindrical connector comprises two parts which can be inserted into one another and is welded to the profile sections at a groove.DE 20 2011 001 320 U1 discloses a frame for fastening photovoltaic modules.DE 20 2007 003 060 U1 discloses a connecting element for mounting support structures for rails of gathering gates, curtains or for solar modules.DE 20 2006 018 426 U1 discloses a mounting rail system for holding solar modules.DE 296 12 142 U1 discloses a guiding device for sliding doors in longitudinal side walls of vehicle superstructures.EP 1 013 865 A2 discloses a slide rail for a sliding gate.It is therefore the object of the present invention to provide a sliding door fitting with two profiles arranged at the end face at a joint, which is easy to install and ensures a reliable alignment of the profiles.This object is achieved with a sliding door fitting having the features of claim 1.According to the invention, the profile connector for connecting the profiles can be fixed to the receptacle by pivoting in in a clamping manner, so that the profile connector can be mounted in a simple manner. Assembly can also be effected with already fixed profiles which are fixed, for example, on a furniture carcass. As a result, it is not necessary to first connect the individual profiles to form a unit and then to fasten the unit comprising a plurality of profiles, which can also be several metres long. In addition, by clamping the profile connector, a precise centering of the profiles is achieved. It is particularly advantageous if the centering of the profiles takes place adjacent to the raceways or below the raceways.According to the invention, a pivot axis for pivoting in the profile connector runs parallel to the longitudinal direction of the profiles. This allows mounting to be performed laterally in order to align adjacent profiles.The receptacle is preferably formed by a hook-shaped section into which two angularly oriented resilient webs of the profile connector are inserted. As a result, tolerance compensation can be effected by the profile connector, since the webs are of resilient design and can compensate tolerances both during the production of the profiles and during the alignment of the profiles. Due to the angular orientation of the webs, these can be compressed in a predetermined range in order to then be fixed in the receptacle in a clamping manner. The profile connector can be held locked on the profiles.According to the invention, the profile connector is more elastic than the profiles. The profiles can be produced from a bent steel sheet or aluminum and the profile connector from a plastic, for example from a glass-fibre-reinforced plastic. Other materials may also be used.It is particularly advantageous if both the profile connector and the profiles are produced from extruded profiles. This can reduce the manufacturing cost. This also ensures that the profiles are better matched to one another, as a result of which the tension required for centering the profiles is maintained over a long period of time.According to a further embodiment, the profile connector has at least one additional latching element, preferably in the form of a latching nose or a latching hook. The profile connector clicks on a projection, into a groove or the like at the corresponding location of the profiles. This additional securing improves the assembly and the profile connector is secured against unintentional detachment. The latching connection can also be realized by other latching principles and at other contact points between profile and profile connector. For example, at least one of the resilient webs of the profile connector could be provided in a contact region with serrations or barbs made of a hard material, e.g. steel sheet, which are shaped such that they dig into the relatively softer material of the profile on contact.The profiles are preferably designed as running profiles for a sliding door and form at least one running track for a sliding door fitting. As a result, the fastening of the profiles to a cabinet can be effected efficiently and, in the region of a joint, the sliding doors can be supported gently on corresponding rollers on the profiles. In addition, the rollers wear out less heavily in the area of the running surface if no gaps or steps are present at the joint. For a good support of the running tracks, the receptacle for the profile connector can be arranged below the running tracks, so that a deflection of the running tracks during the movement of the sliding doors is at least reduced.The invention is explained in more detail below on the basis of an exemplary embodiment with reference to the attached drawings. The following are shown: FIG. 1 shows a perspective exploded illustration of a mounting arrangement of a sliding door fitting according to the invention; FIGS. 2A and 2B are two views of the mounting arrangement of FIG. 1 in the mounted position; FIGS. 3A to 3C show several views of the mounting arrangement of FIG. 1 during mounting; FIGS. 4A and 4B are two views of the profile connector of the mounting arrangement of FIG. 1 , FIG. 5 shows a detail view of the profile connector at the receptacle of the profiles, FIGS. 6A and 6B show a mounting arrangement according to a further embodiment of the invention, FIGS. 7A and 7B show two detail views of the profile connector from FIGS. 6A and 6B at the receptacle of the profiles, FIGS. 8A and 8B show a mounting arrangement according to a further embodiment of the invention, and FIGS. 9A and 9B show a detailed view of the profile connector from FIGS. 8A and 8B at the receptacle of the profilesA mounting arrangement 1 comprises two profiles 2 and 3 which have the same cross section and are to be connected to one another via a profile connector 4. The profiles 2 and 3 are made of metal, for example aluminum or bent steel sheet, and comprise a hook-shaped portion 5 on which a receptacle 6 is formed. The hook-shaped section 5 is arranged below raceways 7 and 8 which serve for receiving a sliding door fitting with running rollers. The rollers are then guided in the tracks 7 and 8 and are intended to be moved over a joint between the two profiles 2 and 3.Each profile 2, 3 comprises a vertical section 9 and an upper horizontal section 10, which can be fixed to a cabinet. In the region of the vertical section 9, there are furthermore provided openings 11 for the mounting of screws 12, by means of which openings the profile connector 4 can be secured.The profile connector 4 is inserted with a section 14 into the receptacles 6 on the profiles 2 and 3 and fixed there in a clamping manner. The profile connector 4 is made of plastic, for example, and comprises an angular section with a vertical contact surface 15, in which openings of screw channels 16 are recessed. The profile connector 4 is designed symmetrically to a central plane and can thus be connected on each side to one of the profiles 2 and 3.FIGS. 2A and 2B show the mounting arrangement 1 with the profile connector 4. The profiles 2 and 3 are aligned in the longitudinal direction and are connected to one another in the region of a joint 30 via the profile connector 4.For the mounting of the profiles 2 and 3, they can first be mounted on a cabinet, as shown in FIG. 3A. The vertical section 9 and the horizontal section 10 of the profiles 2 and 3 bear against a cover plate 20 of a piece of furniture cabinet and can be fixed there. In order to connect the adjacent profiles 2 and 3 to one another in the region of the joint 30 and to avoid steps or gaps in the region of the raceways 7 and 8, the profile connector 4 is positioned with the section 14 in the region of the receptacle 6. The section 14 comprises two resilient webs 17 and 18 oriented at an angle, wherein the lower resilient web 17 is first inserted into the curved region of the hook-shaped section 5. The profile connector 4 is then pivoted, in accordance with FIG. 3B, about an axis which is aligned parallel to the longitudinal direction of the profiles 2 and 3. In this case, the second resilient web 18, which is oriented at an angle of between 30° and 120° to the web 17, is likewise inserted into the receptacle 6, wherein the webs 17 and 18 are compressed in order to be fixed in a clamping manner in the receptacle 6.The final assembly position is shown in FIG. 3C. The resilient webs 17 and 18 bear in a clamping manner within the receptacle 6, which is formed below the raceways 7 and 8. As a result, the profiles 2 and 3 are aligned and stabilized in the region of the joint 30, since the profile connector 4 rests with a vertical section 15 on the section 9 of the profile 2 or 3 and adjoins the underside of the cover 20 of the furniture cabinet with an upper horizontal section. In this case, the profile connector 4 is fixed to the section 9 via a screw 12 screwed into the screw channel 16, with the result that, in the event of a vertical load in the region of the raceways 7 and 8, the profile connector 4 forms a support against preventing or rotating the profiles 2 and 3.In FIGS. 4A and 4B, the profile connector 4 is illustrated in detail. The angular section with the vertical section 15 and the upper horizontal surface 25 is reinforced by a plurality of reinforcing ribs 19, in the region of which the two screw channels 16 are also formed. A central marking 26 is provided on the profile connector 4 in order to facilitate a symmetrical alignment of the profile connector 4 with respect to the joint 30 of the profiles 2 and 3.As can be seen in the enlarged illustration of FIG. 5, the lower resilient web 17 bears with two contact points 21 and 22 in the region of the rounded hook-shaped portion 5 and can be pivoted about these contact points 21 and 22. The upper resilient web 18 abuts a contact point 23 on the underside of the raceways 7 and 8 and ensures a clamping fixing of the profile connector 4. the webs 17 and 18 can in this case compensate tolerances between adjacent profiles 2 and 3 both with regard to the profile geometry and with regard to the mounting of the profiles 2 and 3 and ensure independent centering.In the exemplary embodiment shown, the profiles 2 and 3 are used for aligning a rail of a sliding door fitting formed from a plurality of profiles 2 and 3. It is of course also possible to provide the profile connector 4 for other purposes of use in which adjacent profiles are to be fixed and aligned to one another in the joint region.In addition, the locking or clamping of the profile connector 4 takes place via two webs 17 and 18 arranged at an angle. It is of course also possible to provide other clamping elements which make it possible for a portion of the profile connector to be pivoted in at a receptacle.The openings 11 and / or the screw channels 16 can also have a non-circular geometry, and can be designed, for example, as an elongated hole. As a result, the profile connectors 4 can be used for different profiles 2, 3. The reinforcing ribs 19 shown in the example can also have a different geometry, or the profile connectors 4 can also be designed completely without stiffening elements.In FIGS. 6A and 6B, a connection between modified profiles 2' and 3' and profile connectors 4' without screws is shown. In this case, the profile connectors 4' are fixed to the profiles 2' and 3' by at least one latching hook 27. The profile connector 4' has at least one latching hook 27 which is shaped such that, during assembly, it latches on a rear side of the profiles 2', 3' behind a projection 28 which is arranged on the vertical section 9 on the side facing away from the tracks 7 and 8. Except for the projection 28, the profiles 2' and 3' correspond to the preceding exemplary embodiment.In FIGS. 7A and 7B, the assembly of the profile connector 4' is shown in detail. During the assembly and disassembly of the profile connector 4', no additional tool is required. The profile connector 4' can also be formed narrower, as a result of which less material is required. The latching hook 27 and / or the projection 28 advantageously consists of an elastic material. Fixing can also be effected by riveting, adhesive bonding, clipping or the like. It must always be ensured that the connecting elements do not have any negative effects on the movement of the guide rollers in the raceway 7, 8, are suitable for the intended use and ensure a long-lived connection.In FIGS. 8A, 8B, 9A and 9B, a further embodiment of the mounting arrangement according to the invention is shown with profiles 2" and 3" which correspond to the profiles 2 and 3 except for a projection 31. A profile connector 4"has an angular section 15", and a hook-shaped section 5", with resilient webs 17 and 18. In the region of the upper web 18 a latching receptacle 29 is formed which latches behind a projection 31 of the profile 2, 3 during assembly and thus additionally secures the profile connector 4", against undesired detachment from the profiles 2", 3". The latching receptacle 29 and the projection 31 can be formed differently in this case. The latching receptacle 29 and / or the projection 31 can also have a reinforcement in the contact region. The fixing of the profile connector 4"to the profiles 2", 3" can be produced both by means of screws 12 and by means of other detachable or non-detachable fastening possibilities. The profile connector 4 can also additionally have stiffening elements if required. Instead of a latching nose or a projection, a recess can also be present.In the above-described figures, for reasons of simplification, the existing cover plate of the furniture cabinet is not shown.List of reference characters1, 1' Mounting arrangement 2, 2', 2" Profile 3, 3', 3" Profile 4, 4', 4"Profile connector 5, 5"Hook-shaped section 6 Receptacle 7 Track 8 Track 9 Section 10 Section 11 Opening 12 Screw 14 Section 15 Vertical section 15"Angular section 16 Screw channel 17 Web 18 Web 19 Reinforcing rib 20 Cover plate / cover 21 Contact point 22 Contact point 23 Contact point 25 Upper horizontal surface 26 Marking 27 Latching hook 28 Projection 29 Latching receptacle 30 Contact point 31 Projection
