Description

The invention relates to a guide system for a sliding door of a rail vehicle, comprising a in the sliding direction of the sliding door sliding carrier and a linear roller guide with a rail and at least one carriage, which is mounted on the rail by means of rotating rolling elements. The rail mounted on the carrier or comprises of this. Furthermore, the guide system comprises a console or a plurality of brackets with fastening means for fastening the pivot sliding door, which is connected to the at least one guide carriage or is covered by this. The invention also relates to a sliding door module for a rail vehicle with a guide system of the type mentioned and a rail vehicle of the type mentioned.

The swivel sliding door module described in the introduction is known in principle. The carriage of the linear roller guide rolls on the rail and allows the sliding sliding door to be moved. For example, the shows EP 1 314 626 A1 a system in which a respective rail is fixed on the top and the bottom of a carrier, on each of which a carriage is mounted, which surrounds the rail in cross-section on three sides.

This type of storage has several disadvantages. The in the EP 1 314 626 A1 used linear guide is mainly known from the construction of machine tools, in which the exact guidance of machine parts is essential. In the construction of rail vehicles comparable to a machine tool rigid structure with reasonable effort, however, can not be achieved and not desirable for reasons of weight alone. Due to unavoidable deformations and movements in the structure, therefore, the known linear guide braces and therefore has only a comparatively short life. In addition, the known linear guide relative to the cross-section also relatively wide and thus constructed guide system for a sliding door sliding accordingly deep.

The object of the invention is therefore to provide an improved guide system for a sliding door of a rail vehicle. In particular, the life of the linear guide used is to be extended and the installation depth of the guide system to be reduced.

The invention is achieved by a guide system of the type mentioned above, which also has the features of the claim mark.

The invention is also achieved by a sliding door module for a rail vehicle with a guide system of the type mentioned, comprising a sliding door attached to the console or the consoles.

Finally, the invention is also achieved by rail vehicle, comprising at least one sliding sliding door module of the type mentioned.

The newly used linear roller guide is at the same distance of the rolling planes or contact areas based on the cross section less wide than that in the EP 1 314 626 A1 used linear roller guide. This effect is enhanced when an orbit of the rolling elements is arranged in the carriage. As a result, the rolling planes / contact areas move comparatively far outwards, which has a positive effect on the stability of the linear roller guide. With the same stability can thus be used a significantly narrower linear roller guide, as is possible in the prior art. As a result, the depth of the guide system for the sliding door pivot can be significantly reduced.

The newly used linear roller guide is also less prone to distortion than the linear roller guide used in the prior art. Despite the inevitable deformations and movements in the construction of the rail vehicle, the newly used linear guide braces little and therefore has a relatively long life.

Linear rolling guides of the type mentioned are rolling guides that can be performed with balls or rollers as rolling elements. The rolling elements form the link between the profile rail and guide carriage in a contact area. The rolling elements currently not in contact with the rail are passed over a return area (eg return channel) from the end of the contact area to its beginning or vice versa. The rolling elements So hike in a closed track. As a rule, this orbit is arranged essentially in one plane, the "orbital plane". In this case, an oval-shaped path may be provided, or there are successively provided a plurality of oval-shaped or circular tracks, which are arranged in the same plane and form a contact area in their entirety. In addition, multiple tracks may also be in different but parallel planes. Finally, the tracks can also cross each other. For example, an orbit may leave the orbital plane in the reverse region to allow for intersection with another orbit. In the context of the invention, however, such orbits are nevertheless to be regarded as "arranged substantially in one plane". Optionally, the rolling elements can also be arranged in a rolling element cage.

It should be noted at this point that the features of the invention are particularly suitable for use in a sliding-type sliding door or in a swivel-sliding module. Nevertheless, the invention can also be used for a sliding door or a sliding door module in which or a pivot mechanism is missing.

Further advantageous embodiments and modifications of the invention will become apparent from the dependent claims and from the description in conjunction with the figures.

It is advantageous if the contact surface of the profile rail with the carrier (in the unloaded state thereof) is oriented substantially horizontally. The profile rail thus mounted projects beyond the carrier in the mounting region of the profile rail in a substantially vertical direction. In this way, an increased clearance height can be achieved without the overall height of the sliding sliding door module would have to be increased. This results in particular in very low rail vehicles or double-decker cars a significant improvement in the entry situation. In particular, in the case of non-planar contact surfaces of the profile rail with the carrier, a substantially horizontal alignment thereof is then present within the meaning of the invention if a resulting contact force between the profile rail and the carrier acts in a substantially vertical direction. Non-planar contact surfaces may, for example, have the shape of a cylinder segment, for example if the profile rail has a circular cross-section.

It is favorable if an imaginary connecting line of two rolling bodies, which contact the profiled rail and are in relation to one another with respect to a mounting face normally aligned heavy axis of the profile cross-section opposite each other, is oriented substantially horizontally. In this way, on the one hand a low overall height of the guide system is achieved, on the other hand horizontally acting forces can be absorbed very well. These can be caused, for example, by pressure fluctuations which occur when two trains or tunnel entrances and exits meet. Due to the relatively large surfaces of the sliding doors, enormous forces are generated, especially in high-speed trains.

It is also favorable if at least one circumferential plane of the rolling elements is aligned substantially horizontally. As a result, a particularly low design of the guide system is achieved. This is the case even if one of two superimposed revolving planes is substantially horizontal and the other obliquely aligned, in particular substantially vertical thereto.

It is furthermore particularly favorable when the rolling elements are arranged in a single row between an end limb of the profile rail and the guide carriage. As a result, the linear guide is particularly tolerant to deformations of the guide system and thus particularly well suited for use in rail vehicles. For the reasons mentioned, the linear guide is also very durable.

It is also favorable if the rolling bodies are arranged in a multi-row, in particular double row, between an end limb of the profile rail and the guide carriage. As a result, this is particularly resistant to rotation about its longitudinal axis.

It is advantageous if two spaced guide carriages are arranged at the ends of a console or a console area. In particular, it is advantageous if the two guide carriages are a maximum of half as long as the console or the console area. As a result, the bearing of the guide carriages remains smooth even with comparatively strong deflection of the carrier or the profile rail.

It is advantageous if the carrier in cross section on both sides of the rail is higher than in the region of the rail. In particular, the carrier has in cross-section on its top and bottom laterally from the rail to an increase. In particular, the carrier may also have a substantially H-shaped or X-shaped or T-shaped cross-section.

As a result, on the one hand, the vertical, on the other hand, the horizontal flexural rigidity of the carrier can be increased. The weight of the pivoting sliding door attached to the guide system as well as vertical impacts / accelerations therefore cause only a comparatively slight bending of the carrier in the vertical direction. Likewise causes a horizontal force component on the sliding door, as they arise in particular by the suction and pressure occurring in tunnels, also a comparatively small deflection of the carrier in the horizontal direction. In addition, a torsional tendency of the wearer is reduced. The carrier can thus be made overall relatively thin-walled, whereby the total weight of the rail vehicle is reduced and its performance is improved. Due to the low deformation of the carrier and the loads of the guide system are reduced, resulting in a longer life or longer maintenance intervals same result.

It should be noted at this point that the features mentioned can also be advantageous if the contact surface of the profiled rail is aligned substantially vertically with the carrier. The features mentioned can thus form the basis for an independent invention.

It when the guide system comprises two linear guides, wherein a first rail on the top of the carrier and a second rail are mounted on the underside of the carrier is particularly advantageous. In this way, a single carrier can be used for holding a double-wing sliding door. A pivoting sliding door module accordingly comprises a first pivot sliding door attached to the console or the brackets of the lower linear guide and a second pivoting sliding door attached to the console or the brackets of the upper linear guide.

The advantage of the low height of the guide system is particularly evident here. In particular, it is also advantageous if the carrier is constructed symmetrically with respect to its horizontal axis, since then no special mounting direction is observed.

It is also particularly advantageous if the brackets of the lower and upper linear guide are designed essentially identically and are rotated by 180 ° about a horizontal axis aligned normal to the profile rail. As a result, the number of different components of the guide system is reduced, thereby simplifying the production and storage.

It is advantageous if the fastening means are arranged on the brackets of the lower and upper linear guide at substantially the same height. This makes it possible to build the door similar or even identical. The production of a sliding door module or the storage of the parts required for its manufacture or repair is thus once again simplified.

It is particularly advantageous if the swiveling sliding door module comprises at least one rotary joint which permits a rotation of the swiveling sliding door relative to the profile rail about an axis of rotation oriented substantially horizontally and transversely to the sliding direction and / or a substantially vertically oriented axis of rotation.

Frequently occurring deformations of the carrier of the profile rail and thus of the profile rail itself are - as already mentioned above - deflections in the vertical and horizontal directions and a twist / twisting the same. A deflection in the vertical direction is essentially caused by the weight of the sliding door and vertical shocks / accelerations. Horizontal deflections can be caused, for example, by pressure fluctuations which occur when two trains or tunnel entrances and exits meet. Due to the relatively large surfaces of the sliding doors, enormous forces are generated, especially in high-speed trains. A rotation of the carrier is formed in asymmetrical cross-section with respect to the direction of the introduced force. Due to the complexity of the forces occurring and the usually complex cross-sectional shape of the carrier and the rail mounted thereon torsion is practically unavoidable.

Due to the system so deflections and torsion of the said carrier and the rail mounted thereon are virtually impossible to prevent. Since the swivel sliding door of this deformation due to their rigidity (especially against vertical deflection and torsion) can not or only partially follow, it comes to tension in the storage between the carriage (carriage) and the rail. Bearing damage or reduced service life of the linear guide can be the result.

In order to keep the loads of the bearing within limits, the support for the rails according to the prior art are relatively stiff dimensioned to keep the deformations and thus the tension in the bearings as small as possible. Naturally, this increases the weight of the sliding sliding door module.

By the presented rotary joint is now achieved, however, that a deformation of the rail is made possible, the storage between carriages and rail is not or only slightly charged. Compared to known sliding door modules, a carrier on which the rail is attached, thus be made relatively fragile, since the sliding door (or the door) always remains smooth despite a deformation of the rail and damage in storage between carriage and rail to be avoided. Thus, the life of the storage between carriage and rail can be extended. In addition, the total weight of the rail vehicle can be reduced and its performance improved.

By allowing a rotation about a substantially horizontal and transversely aligned to the sliding direction of rotation axis vertical deflections of the rail can be compensated.

By allowing a rotation about a substantially vertically oriented axis of rotation horizontal deflections of the rail can be compensated.

The rotation can be made possible by a rotary joint or multiple hinges. If the rotation of the sliding door with respect to the profile rail around two mutually transverse axes is made possible, can also be spoken of a "gimbal" of the sliding door.

In principle, a hinge can be provided in the slide, between the console and slide, in the console, between the console and sliding door and / or in the sliding door itself. In the latter case, for example, a mounting surface of the sliding door, to which the console is attached, be articulated to the actual door leaf.

It is advantageous if the at least one rotary joint permits rotation of the pivoting sliding door relative to the profiled rail about an axis of rotation oriented essentially parallel to the sliding direction. By allowing this rotation, a twisting of the rail can be compensated. In particular, if the profile rail has a circular cross-section, a rotary joint which permits a rotation of the pivoting sliding door relative to the profile rail about an axis of rotation aligned substantially parallel to the sliding direction can be dispensed with. If, for example, a substantially rectangular profile rail is used, then a torque can be transmitted between the pivoting sliding door and the profile rail about said rotation axis.

It is favorable if the at least one rotary joint is formed by a shaft rotating in a bearing shell or a roller bearing. The swivel joint is thus formed in this case by a sliding bearing or a rolling bearing that allows the rotation of an axle mounted in the bearing. In this way, the hinge can be turned into reality by readily available means.

It is advantageous if the at least one rotary joint is formed by two rolling surfaces rolling on each other. One of the two rolling surfaces is convex for this purpose, and the other rolling surface is concave with the same or lesser curvature, flat or convex.

It is particularly advantageous if a rolling surface has a generally cylindrical, in particular a circular cylindrical shape. In this way, a rotation about a rotation axis is made possible. Because of the linear contact of the rolling surfaces also comparatively high forces can be transmitted.

In a preferred embodiment, the sliding sliding door module comprises two generally cylindrical rolling surfaces with mutually transverse axes. This allows rotation about two axes of rotation. Such a hinge can thus compensate for the deformations of a rail particularly well. Because of the linear contact of the rolling surfaces, in turn, comparatively high forces can be transmitted.

It is also particularly advantageous if a rolling surface is multidimensionally curved, in particular spherical. In this way, a rotation about several axes of rotation is also possible. Such a hinge can thus also compensate for the deformations of a rail particularly well. Because of the multi-dimensional curvature, the rolling surfaces can roll on each other when rotated about an arbitrary axis, whereby a sliding against each other avoided and the wear of the rolling surfaces is thus reduced.

It is favorable if a weight force of the sliding sliding door presses the two rolling surfaces against each other. Since the two rolling surfaces are then pressed against each other without further measures, the sliding door module in this case can be structurally made relatively simple, resulting in a further weight and price advantage.

It is advantageous if a convex rolling surface arranged on the bracket is pressed by the weight force of the sliding sliding door onto a horizontally aligned planar rolling surface of the slide. In this way results in a particularly simple and inexpensive construction, especially when the linear guide is designed as a linear roller guide. As a rule, the carriage consists of high-strength and hardened steel and is ground at the top. In this way, the top of a commercially available carriage carriage can act as a rolling surface without further action. Therefore, only one convex rolling surface needs to be provided on the console side in order to realize a rotary joint in the sense of the invention.

It is also advantageous if two rolling rolling surfaces rolling against each other are secured against lifting by means of a counter-holder. This avoids that the rolling surfaces (significantly) can lift off each other. In particular, in the case of heavy pivot sliding doors, damage to the rolling surface can thus be avoided or at least reduced, which can result from counter-striking of the rolling surfaces. Without further action For example, vertical impacts on the rail vehicle may cause the pivot sliding door to lift and subsequently impact the bearing surface and destroy it. Especially with hardened surfaces parts of the bearing surface could flake off.

It is also particularly advantageous if the counter-holder presses the rolling surfaces together with the aid of a spring force and / or by elastic deformation. In this way it is achieved that the counter-holder moves when rolling the rolling surfaces relative to the rolling surface held, in particular can rotate relative to this and a rolling of the rolling surfaces against moderate resistance is possible. All types of springs and elastic components (for example rubber buffers) can be used. Alternatively or additionally, also the counter-holder can be designed so that it opposes the rolling of the rolling surfaces by elastic deformation only moderate resistance.

Furthermore, individual features or combinations of features from the illustrated and described different embodiments may represent for themselves, inventive or inventive solutions.

All statements on ranges of values in the description of the present invention should be understood to include any and all sub-ranges thereof, e.g. is the statement 1 to 10 to be understood that all sub-areas, starting from the lower limit 1 and the upper limit 10 are included, ie. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10.

The FIGS. 1 and 2 show an exemplary and schematically illustrated guide system 1 for a sliding door of a rail vehicle in an oblique view ( Fig. 1 ) as well as in the oblique section ( Fig. 2 ). The guide system 1 comprises a carrier 2 which is oriented in the sliding direction of the pivoting sliding door and a linear roller guide with two profiled rails 3 and two guide carriages 4, wherein the profiled rail 3 is fastened to the carrier 2 (for example screwed with this) or is covered by this in the form of a profile area and the at least one carriage 4 is mounted on the rail 3 by means of rotating rolling elements 5. The profile rail 3 has a substantially C-shaped or U-shaped cross-section, wherein the guide carriage 4 is mounted between the opposite end legs of the C-shaped or U-shaped cross section. Furthermore, the guide system comprises a plurality of brackets 6 with fastening means 7 (here fastening holes) for fastening two pivot sliding doors (not shown), the brackets 6 is connected to the at least one carriage 4 or is covered by this in the form of console areas / is. The contact surface of a profile rail 3 with the carrier 2 is aligned substantially horizontally in this example. The rail 3 extends in the Fig. 1 not over the entire length of the carrier 2. Of course, but this may be the case.

The carrier 2 may be fixedly connected to the rail vehicle or else be movable. In this case, the carrier 2 is exposed transversely to the sliding direction of the sliding sliding doors, so that the sliding sliding doors can be moved. In particular, in such a construction is to pay attention to low weight of the entire arrangement, as this comparatively heavily loaded the guide system of the carrier 2 (not shown).

In the Fig. 1 is good to see that the guide system 1 in this example has two linear guides, wherein a first rail 3 is mounted on the upper side of the carrier 2 and a second rail 3 on the underside of the carrier 2. In this way, a single carrier 2 can be used for holding a double-wing sliding door. The advantage of the low height of the guide system is particularly evident here. In particular, it is also advantageous if the carrier 2 is constructed symmetrically with respect to the horizontal plane, since then no special mounting direction is observed.

Good to see in Fig. 1 Also, that the brackets 6 of the lower and upper linear guide in this example designed substantially identical and rotated by 180 ° about a horizontal and normal to the rail 3 aligned axis. As a result, the number of different components of the guide system 1 is reduced, thus simplifying the production and storage.

Finally, in the Fig. 1 Also good to see that the fastening means 7 are arranged on the brackets 6 of the lower and upper linear guide in this example at substantially the same height. This makes it possible to build the door similar or even identical. The production of a sliding door module or the storage of the parts required for its manufacture or repair is thus once again simplified.

As in particular from the Fig. 2 is clearly visible, the profile rails 3 extend beyond the carrier 2 in this example in the mounting region of the rails 3 in the vertical direction. In this way, an increased clearance height can be achieved without the overall height of the sliding sliding door module 1 would have to be increased (see also Fig. 10 ).

From the Fig. 2 is also apparent that in this embodiment, an imaginary line connecting two rolling elements 5, which touch the rail 3 and are in relation to a normal to the mounting surface aligned gravity axis 8 of the profile cross-section opposite each other, is oriented substantially horizontally. Furthermore, a circumferential plane of the rolling elements 5 is aligned substantially horizontally. Moreover, from the Fig. 2 also be seen that an orbit 9 of the rolling elements 5 is arranged in the carriage 4. Thus, the depth of the guide system 1 can be kept low. Finally, the shows Fig. 2 Also, that the rolling elements 5 are arranged in a single row between an end leg of the rail 3 and the carriage 4. As a result, the linear guide is particularly tolerant to deformation of the guide system 1 and thus particularly durable.

The FIGS. 3 and 4 show two examples of the orbits 9 of the rolling elements 5 in the carriage 4. In the Fig. 3 run the rolling elements 5 along oval orbits 9, in the Fig. 4 along circular orbits 9. The orbits 9 are in the presented variant of the guide system 1 in a horizontal plane. By the measures mentioned on the one hand a particularly low overall height of the guide system 1 is achieved, on the other hand horizontally acting forces can be very well received, which may be caused for example by acting on the sliding door sliding pressure fluctuations. In general, the circumferential planes of the rolling elements 5 can also be slightly inclined with respect to the horizontal, without the overall height of the guide system being excessive increases. It has proven to be advantageous if a circulating plane is inclined by not more than 20 ° relative to the horizontal. It is also conceivable that one of two superposed circumferential planes is substantially horizontal and the other obliquely aligned thereto, in particular substantially vertical thereto.

Fig. 5 shows another example of a carriage 4 in an oblique section. In this case, the two orbits 9 cross each other in their end regions or reverse regions. The right-hand orbit 9 is thereby lifted slightly from the orbit plane in which the orbit 9 largely runs, and the left-hand orbit 9 is slightly lowered. As a result, a comparatively large path radius is achieved with only a small width of the guide carriage 4 and thus only a small depth of the guide system 1. In the context of the invention, the orbits 9 shown are to be regarded as "substantially arranged in one plane" because of the only slight deviation from the planar shape.

From the Fig. 2 is further seen that the carrier 2 in the illustrated example in cross section on both sides of the rails 3 is higher than in the region of the rail 3. The carrier 2 has in cross-section thereto on its top and bottom laterally from the rails 3 an increase. The carrier 2 thus has in this example a substantially H-shaped or X-shaped or T-shaped cross section. As a result, on the one hand, the vertical, on the other hand, the horizontal flexural rigidity of the carrier 2 can be significantly increased. Forces in both the horizontal and in the vertical direction therefore cause only a comparatively small bending of the carrier 2. Due to the comparatively high torsional moment of inertia, a rotation of the carrier 2 also remains low. It should be noted at this point that the features mentioned can also be advantageous if the orbital plane of the rolling elements is aligned vertically (cf. Fig. 10 ).

Finally, in Fig. 2 good to see a hinge, which allows in this example, a rotation of the pivoting sliding door relative to the rail 3 about an aligned substantially parallel to the sliding direction of rotation axis. As a result, on the one hand a twisting of the rail 3 can be compensated, on the other hand, it is also possible to easily adapt the guide system 1 to different installation situations. In particular, modern rail vehicles do not necessarily have vertically extending side walls, but rejuvenate to the top. As a result, the sliding door is slightly inclined relative to the guide system 1. With the help of the rotary joint, the illustrated guide system 1 but also be applied without restriction in such cases. The rotary joint is formed in this case by a rotating shaft in a bearing shell 10, but of course conceivable is the use of a rolling bearing. It would also be possible to form the joint from a ball head mounted in a ball socket, so that rotations about several axes are possible. Likewise, a universal joint could be provided.

Admitting a rotation about the longitudinal axis is by no means the only way to allow a rotation between the sliding door and sliding rail 3. It is also conceivable that the guide system comprises at least one rotary joint, which allows a rotation of the pivoting sliding door relative to the rail 3 about a substantially horizontal and transverse to the sliding direction aligned axis of rotation and / or a substantially vertically oriented axis of rotation.

The FIGS. 6 and 7 show two illustrative examples of how a rotation of the pivoting sliding door is made possible around a substantially horizontal and transverse to the sliding direction aligned axis of rotation.

The Fig. 6 shows a section BB, from which it is apparent that the console 6 in the region of the carriage 4 has a convex portion which rests on the flat surface of the carriage 4, whereby a rotary joint is formed with two rolling rolling surfaces rolling against each other. Because the guide carriage 4 is generally made of high-strength and hardened steel, the upper side of a commercially available guide carriage can act as a rolling surface without any further measures.

Concretely, the rolling surface arranged on the bracket 6 has a cylindrical shape, with the projecting members normal to the sheet plane. The console 6 and thus attached pivoting sliding door can thus be rotated about a substantially horizontal and transverse to the sliding direction of rotation axis relative to the rail 3, whereby vertical deflections of the rail 3 can be compensated.

In this example, the two rolling surfaces are pressed together by a weight force of the pivoting sliding door. In addition, the two rolling rolling surfaces are secured against lifting by means of an optional counter-holder 11. The counter-holder 11 is fixed in position with the aid of dowels 12 with respect to the console 6 and screwed by means of screws 13 with this. To still allow rotation of the console 6 relative to the rail 3 as in Fig. 6 also represented the counter-holder 11 may be convex and / or a slight clearance be allowed. In the latter case, a lifting of the upper Wälzflächen is therefore possible in principle, however, the "drop height" (ie the game) is chosen so low that damage to the Wälzflächen when striking the console 6 can be avoided on the carriage 4.

Fig. 7 shows a variant of the guide system, the in Figure 6 variant is very similar. In contrast, the optional counter-holder 11 presses the rolling surfaces together by means of a spring force and / or by elastic deformation. Specifically, the bracket 6 is screwed to the counter-holder 11 via two rubber buffers 14, which allow rolling of the rolling surfaces under moderate effort, but prevent lifting of the rolling surfaces or at least complicate. In the in Fig. 7 illustrated example, the counter-holder 11 has no convex area, but of course it is also conceivable that he as in Fig. 6 is shown formed, whereby a rolling of the rolling surfaces is facilitated.

In principle it is for those in the Fig. 7 shown arrangement sufficient when the console 6 can move relative to the anvil 11 translational. In a variant of in the Fig. 7 illustrated arrangement, the fit of the dowel 12 but also be relatively loose or the dowel be mounted in a rubber sleeve, so that a tilting of the console 6 and the counter-holder 11 against each other are possible. In accordance with loose fit the backstop 11 can even then rest flat on the carriage 4, when the console 6 is tilted relative to the carriage 4 or rotated.

Although in the 6 and 7 shown joints allow a rotation of the bracket 6 relative to the rail 3 about a substantially horizontal and transverse to the sliding direction aligned axis of rotation, the joints shown by appropriate arrangement are also provided for rotation about a vertical axis of rotation or about an axis of rotation aligned substantially parallel to the sliding direction.

Fig. 8 shows very simplified a swivel that allows rotation about two axes of rotation. For this purpose, the console 6 and the optional counter-holder 11 have generally cylindrical rolling surfaces with mutually transverse axes. The carriage 4, however, again has flat rolling surfaces. Such a hinge can thus compensate for the deformations of a rail 3 particularly well. Because of the linear contact of the rolling surfaces also comparatively high forces can be transmitted.

Fig. 9 shows very simplified a swivel that allows rotation around any axis of rotation. For this purpose, the console 6 and the optional counter-holder 11 have multi-dimensionally curved rolling surfaces, in particular spherical rolling surfaces. Such a hinge can also compensate for the deformations of a rail 3 also particularly well. Because of the multi-dimensional curvature, the rolling surfaces can roll on each other when rotated about an arbitrary axis, whereby a mutual sliding is avoided and the wear of the rolling surfaces is thus reduced.

By providing a rotary joint or a plurality of hinges, a deformation of the rail 3 is made possible without the storage between guide carriage 4 and rail 3 to brace. Compared with known sliding sliding door modules, a carrier 2, on which the rail 3 is fixed, therefore, be made comparatively fragile, since the sliding door (or the door leaf) despite a deformation of the rail always remains smooth and damage in storage between carriage 4 and 3 be avoided.

Particularly successful is a stress-resistant storage, when in the course of the console 6 a plurality of relatively short guide carriage 4 are arranged, in particular when at the ends of the console 6, two relatively short guide carriage 4 are arranged. As a result, the bearing of the guide carriages 4 remains smooth even with a comparatively strong deflection of the carrier 2, respectively the profile rail 3. Due to the increased resistance to distortion thus obtained, the use of a swivel joint may be dispensable. In general, it is also possible to use only one carriage 4 per rail 3, provided that the Linear guide inherent tolerance is sufficient to compensate for a deformation of the carrier 2.

The in the FIGS. 6 to 9 Specifically shown articulated supports of the console 6 can be made in particular when the rail 3 is mounted only at the ends, so that the console 6 may include the carriage 4 together with the anvil 11 on all sides (see in particular Fig. 8 and 9 ). If the rail 3 as for example in the Fig. 1 represented on the entire length thereof are connected to the carrier 2, for example, the counter-holder 11 can be omitted or the carriage 4 have a corresponding extension, which in turn can be shared by the console 6 together with the anvil 11 on all sides. In the in the FIGS. 6 and 7 arrangements shown, said extension can be arranged in particular laterally on the carriage 4, in which in the FIGS. 8 and 9 shown arrangements in particular extend in the longitudinal direction.

In general, vertical deflections of the profile rail 3 can be compensated by allowing a rotation of the bracket 6 relative to the rail 3 about a substantially horizontally and transversely aligned to the sliding axis of rotation, horizontal deflections by allowing rotation about a substantially vertically oriented axis of rotation and twisting of the rail by allowing a rotation about an axis of rotation aligned substantially parallel to the sliding direction.

In general, rotations about several axes can be achieved by means of single pivot joints connected in series (cf. Fig. 2 ) and / or be realized by hinges that allow rotations about multiple axes (see Fig. 8 and 9 ). The hinges can also be realized optionally by successive rolling surfaces and / or against each other sliding surfaces (eg pin / slide bushing). Furthermore, the positioning of the joints, as indicated in the above examples, while advantageous, but by no means mandatory. In principle, a swivel joint in the carriage 4, between console 6 and guide carriage 4, be provided in the console 6, between the console 6 and sliding door and / or in the sliding door itself. In the latter case, for example, a mounting surface of the sliding door, to which the console is attached, be articulated to the actual door leaf.

Furthermore, it is also pointed out that the use of compensating joints is of course not bound to a linear roller guide, although there may be a damaging consequence particularly quickly a distortion of storage. Of course, the invention is equally applicable to linear sliding guides of all kinds.

Finally, it is also noted that the application of compensating joints is of course not bound to the specific arrangement of the profile rails 3. Rather, the contact surfaces of the rails 3 to the carrier 2 can also be aligned vertically. Fig. 10 shows an example of a guide system, in which two pivot sliding doors 15 are attached via brackets 6 to the guide carriages 4 of two superimposed linear roller guides. The above teaching is mutatis mutandis applicable to such an arrangement.

The embodiments show possible embodiments of a guide system 1 according to the invention, it being noted at this point that the invention is not limited to the specifically illustrated embodiments of the same or the same, but also various combinations of the individual embodiments are mutually possible and this variation possibility due to the teaching to technical action by objective invention in the skill of those working in this technical field expert. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection.

In particular, it is noted that a guidance system 1 may in reality also comprise more or fewer components than illustrated.

For the sake of order, it should finally be pointed out that for a better understanding of the structure of the guide system 1, this or its components have been shown partially unevenly and / or enlarged and / or reduced in size.

The task underlying the independent inventive solutions can be taken from the description.
