Description

Title: Sliding door suspension with integrated linear drive

description

The invention relates to a sliding door with integrated linear drive, in particular with a linear motor.

Sliding doors are known. If sliding doors are to be provided with a linear drive, the problem arises of modifying existing suspensions only insignificantly or not at all.

The invention is therefore based on the object to solve the aforementioned problem.

The object is achieved by a sliding door hanger according to claim 1. Advantageous developments are specified in the subclaims.

A suspension according to the invention for at least one movable along a travel part, in particular a sliding door, has a guide profile, which is formed along a travel path of the at least one movable member extending longitudinally and side wall sections. The side wall portions are formed to extend in a direction of the longitudinal extent of the guide profile and parallel to a height extent of the movable portion. The side wall sections are also connected to one another at an end remote from the at least one movable part by means of a horizontal wall section. The at least one movable part is guided guided on an end facing the guide profile in the guide profile added. A driver part of a linear drive is operatively connected to the at least one movable part, so that he entrains the at least one movable part during a movement. In the guide profile a receiving space is formed in a space between the horizontal wall portion and the driver part, in which a drive profile is used and fixedly mounted on the guide profile, wherein the linear drive is housed at least with a part in the drive profile and the drive profile above a guide of the movable part in Guide profile is arranged. This makes it possible to provide the moving part with a linear drive using an existing guide profile without the guide profile must be edited. As a result, the possibility of a subsequent conversion to another linear drive or even a deconstruction to a manually operated system is given.

The linear drive can be formed by means of a traction mechanism drive. The traction mechanism drive has at least one traction means, for example in the form of a rope. The traction means is guided circumferentially around two deflection rollers, wherein one of the two deflection rollers is arranged freely rotatably on the drive profile in each case in one end region of the travel path. A drive motor is operatively connected to one of the two deflection rollers or a drive wheel of the traction mechanism drive, which is in drive-operative connection with the traction means. An end remote from the at least one movable part of the driver part is attached to the traction means. Preferably, the deflection rollers are mounted on axles, which in turn are supported on both side wall sections of the drive profile. This is a compact and designed as a module linear drive is formed. The traction means may be formed by means of a pull cable, a toothed belt or a chain. The linear drive can also be formed by means of a spindle drive. A drive motor is operatively connected to a threaded spindle. The threaded spindle is freely rotatably mounted in spindle bearings and arranged to extend in the direction of travel. The spindle bearings are attached to the drive profile or formed with him einstückig. The driver part has a threaded sleeve section on an end facing away from the movable part. The threaded sleeve section has a threaded section designed to be complementary to the threaded section and is screwed onto the threaded spindle by means of this threaded section. Preferably, the driver part has a roller, which is arranged such that it rolls on a side facing the horizontal wall portion along a travel path of the movable part and is supported on the side facing. This prevents bending of the threaded spindle in the direction of the horizontal wall section.

Alternatively, the linear drive can be formed by means of a linear motor. The driver part is preferably formed by means of a main body of a rotor part. A stator of the linear motor is fastened to a mounting part and extends over a predetermined range of the travel path along this area. The rotor has a row of magnets on a side facing away from the movable part. The rotor interacts with the stator in such a way that energizing the stator causes the rotor to move, wherein the base body is operatively connected to the movable part on a side facing the movable part.

The plurality of possible linear drives with the aforementioned advantages offers the freedom to select the linear drive according to its own merits and not to be limited to a specific linear drive. - A -

The movable part may be a sliding door leaf (1), curved sliding door leaf, revolving door leaf, folding door leaf or also a partition wall module.

According to the invention, provision is further made for the guide profile to have a number of receiving chambers arranged next to one another and aligned essentially parallel to one another transversely to a direction of movement of the at least one movable part. This makes it possible to use several sliding doors, each with its own linear drive using the existing guide profile.

Further features and advantages of the invention will become apparent from the following description of preferred embodiments.

Figure 6: a sliding door hanger according to a second embodiment of the invention and Figure 7: Sliding door hinges according to other embodiments of the invention.

As shown in FIG. 1, a suspension according to a first embodiment of the invention has a sliding door leaf 1 which is guided in a guide profile 10. In the example shown in FIG. 1, the sliding door leaf 1 is formed by means of a glass pane enclosed in a frame 4. The frame 4 has an upper frame part 5, which may be integrally formed with the rest of the frame 4. The sliding door leaf 1 is guided at a lower edge by means of rollers 6 in a bottom rail 3, which prevents a breaking out of the sliding door leaf 1 in ± z coordinate direction in Figure 1. In addition, the roller 6 can be provided for receiving the weight of the sliding door leaf 1, so that upper, provided in the guide profile 10 guide rollers 21 are relieved.

Alternatively, the lower rollers 6 are missing, so that the sliding door leaf 1 is freely suspended in the guide profile 10.

The upper frame part 5 has on an upper side, ie on a side facing the guide profile 10, seen in the y-coordinate direction, preferably at both ends in each case a roller holder 8, of which in Figure 1, only the viewer facing roller holder 8 is visible. On each roller holder 8, a guide roller 16 with respect to the respective roller holder 8 are arranged freely rotatable on the right and left side, viewed in the x-coordinate direction parallel to an xz plane. The guide rollers 16 each run on an associated guide rail 11 of the guide profile 10. In the example shown in FIG. 1, the guide rails 11 have a crown-shaped running surface. The guide rollers 16 have a running surface complementary to the running surface. This type of running surfaces prevents the guide rollers 16 from breaking away in the ± z coordinate direction.

Above the guide rollers 16, a drive profile 20 is inserted or inserted into the guide profile 10. The drive profile 20 is provided for receiving or for storing parts of a linear drive not visible in FIG.

The rollers 6 are preferably mounted resiliently with respect to the sliding door leaf 1. Ie. Rotary axes of the rollers 6 are preferably not fixedly housed in the sliding door leaf 1 or fastened thereto. Preferably, the axes of rotation of the rollers 6, as shown in Figure 2A, each housed in a free end of a leg spring 27 and attached thereto. The respective other end of the respective leg spring 27 is fastened or accommodated in a recess which is formed in the sliding door leaf 1 or its frame 4. A middle section of the respective leg spring 27 is supported on a surface of the sliding door leaf 1 facing the bottom rail 3. One side of the recess, at which the middle section comes to lie, preferably has a spring-mounted projection. When inserting the leg spring 27 this is inserted with a free end to which the roller 6 is not mounted in a direction indicated in Figure 2A, located in the recess bearing axis. Then, the center section is pivoted into the recess and presses while the projection away. If the center section is guided past the projection, the projection is moved back to its starting position due to its resilient mounting, so that it is below the center of the projection. section comes to rest. The projection effectively prevents the center section from coming out of the recess.

Alternatively, the suspension, as shown by way of example in Figure 2B, take place by means of a coil spring 27. In the present case, the frame 4 has a receptacle for a holding part 24 on an underside. The receptacle has a holding part receiving portion and a spring receiving portion. The holding part receiving portion preferably has a latching lug on two opposite inner walls. The holding part 24 has on corresponding surfaces in each case a recess in the form of a groove, which, however, is not formed continuously. The grooves begin at an edge of a lower surface of the support member 24, each extending in the direction of sliding door leaf 1 and terminate just below an edge of an upper surface of the support member 24. The lower and upper surfaces are horizontal, d. H. parallel to the x-z plane in FIG. 2B. The upper surface forms a stop for a corresponding latching lug, so that the holding member 24 within the recess along the latching noses move up and down but can not fall out. The holding part 24 has a projection on the upper surface which projects in the direction of the sliding door leaf 1, that is to say in the direction of the sliding door leaf 1. H. in the y-coordinate direction in FIG. 2B. On the projection, the coil spring 27 is attached.

FIG. 3A shows a variant of a linear drive in the form of a traction cable drive which is integrated in the drive profile 20 and is designed as a traction mechanism drive 50. On the right in FIG. 3A, the drive profile 20 is shown in section along a line A-A in FIG. On the left in FIG. 3A, the same drive profile 20 is shown in section along a line B-B on the right in FIG. 3A. A drive motor 54 is dimensioned such that, seen in the ± z coordinate direction, it is completely received by the drive profile 20. In the drive profile 20, a motor mount 23 is used, in which the drive motor 54 is rotatably received with respect to the drive profile 20.

The motor mount 23 and the drive motor 54 are designed such that neither the motor mount 23 nor the drive motor 54 can rotate about an x-coordinate axis in FIG. 3A. This is preferably achieved in that the motor mount 23 is formed in contact areas with inner surfaces of the drive profile 20 complementary to this. In these contact areas, the motor mount 23 is in positive and / or non-positive engagement with inner surfaces of the drive profile 20. The motor mount 23 has a space for receiving the drive motor 54. This receiving space is formed in contact areas with the drive motor 54 complementary to an outer contour of the drive motor 54 in these contact areas. In the example shown in Figure 3A, the motor mount 23 is formed in two parts and has, seen in ± x coordinate direction, in the cross section right and left rectangular recesses into which the drive motor 54 is inserted with complementary projections formed. If a static friction between the motor mount 23 and the drive motor 54 is insufficient, the drive motor 54 can additionally be secured or fixed in the motor mount 23, for example by means of screws.

At a free end of an output shaft of the drive motor 54, a gear part in the form of a spur gear 57 is arranged rotationally fixed. The spur gear 57 is operatively coupled to a crown wheel 58, which in turn rotatably connected to a first guide roller 53 or, as indicated on the left in Figure 3A, formed integrally with her. Each deflection roller 53 has a circumferential groove, in which a traction cable designed as a cable means 52 is laid and guided. At a lower portion of the rope, a driver 51 is fixed, which in turn is attached to a sliding door panel 1, not shown, or integrally formed with this or an upper frame part 5 of the sliding door leaf 1.

At a side facing away from the drive motor 54 end of the drive profile 20, a second guide roller 53 is freely rotatably arranged around which the cable is also guided, so that a circumferential cable drive is formed. Rotation axes 56, 56 of the deflection rollers 53, 53 are preferably supported on mutually opposite side wall sections 22 of the drive profile 20 and mounted freely rotatable.

Since all parts of the linear drive are fixedly mounted on or in the drive profile 20, this results in a drive module which is simply inserted or inserted into the guide profile 10 of the above-described sliding door suspension, which makes it easy to assemble or retrofit a previously manually operated sliding door by means of a guide profile 10 suspended or guided sliding door leaf 1 allows.

If the drive motor 54 is dimensioned larger than a receiving space of the drive profile 20, it is provided that the drive motor 54 be attached in a fixed manner to the right-hand end of the drive profile 20 on the left in FIG. 3A.

According to an embodiment shown in FIG. 3B, the motor holder 23 has an insertion section 23a and a holding section 23b for this purpose. The insertion section 23a serves to insert or insert the motor mount 23 into the drive profile 20. Advantageously, the insertion section 23a is designed so that it fully accommodates the receiving cavities of the drive profile 20 in the region of the insertion section 23a. constantly filling. Ie. The motor holder 23 is held by inner surfaces of the drive profile 20, which are in contact with the insertion portion 23 a. A fixation of the insertion section 23a in the drive profile 20 can be realized by means of clamping, by means of screwing, by means of latching connection (s) or any other possible fixation. At an end of the insertion section 23a facing away from the drive profile 20, the holding section 23b adjoins, which serves to receive the drive motor 54. The drive motor 54 preferably has a non-circular outer contour, while the holding portion 23b preferably has a complementary to this outer contour formed inner contour. When inserting the drive motor 54, this thus comes into positive engagement with the holding section 23b, so that the drive motor 54 is arranged rotationally fixed with respect to the holding section 23b.

The insertion portion 23a has a through hole which serves to receive and feed the output shaft of the drive motor 54. In the passage opening, a freely rotatable sleeve is preferably arranged, which is received in the through hole, for example, ball-bearing and freely rotatable. Alternatively, the sleeve itself serve as a pivot bearing for the output shaft of the drive motor 54. The output shaft projects from an end of the insertion section 23a facing the drive profile 20. The spur gear 57 described above is arranged rotationally fixed at this protruding end of the output shaft.

In order to prevent the drive motor 54 from falling out of the holding section 23b, it is preferably provided that the drive motor 54 is held in the receiving space of the holding section 23b by means of clamping. Alternatively or additionally, the drive motor 54 can be locked in the holding section 23a by means of latching connection (s). For this purpose, on a outer surface of the drive motor 54 and on corresponding receiving surfaces of the holding portion 23b suitably arranged locking projections or locking receptacles are provided.

Again alternatively or additionally, a motor fixing can be provided, which is formed by means of a cover 23c, which is placed after insertion of the drive motor 54 in the holding portion 23b on the drive profile 20 remote from the end of the holding portion 23b. The holding section 23b preferably has threaded bores on the end facing away from the drive profile 20. The lid 23c has passage openings at corresponding points. Fixing screws are screwed through the through holes into a respective threaded hole of the holding portion 23b. Alternatively or additionally, the lid 23c can in turn be fastened to the holding section 23b by means of latching connection (s).

The motor mount 23 is preferably designed such that, after insertion into the drive profile 20 and after insertion of the drive profile 20 into the guide profile 10, it at least does not protrude beyond an upper outside of the horizontal wall section 13 of the guide part 10. This makes it possible to attach the guide profile 10 including linear drive, for example, to a ceiling.

If the drive motor 54 has external dimensions which make it impossible to mount the spur gear 57 described above on the output shaft of the drive motor 54 in a torque-proof manner and to couple it to the crown wheel 58, an arrangement according to FIG. 3C is provided. In this case, a transmission is preferably used in the holding section 23b, which has a connection. Set a rotation axis of the spur gear 57 with respect to a rotation axis of the output shaft of the drive motor 54 bridged.

The passage opening of the insertion section 23a continues in the holding section 23b at the end facing the insertion section 23a up to a predetermined extent. Ie. the holding portion 23b has an axle receiving portion which has a cross-sectional shape substantially corresponding to a cross-sectional shape of the through hole of the fitting portion 23a. The spur gear 57 described above is arranged rotatably on one end of a drive shaft. The drive shaft extends from the spur gear 57 through the insertion portion 23a into the axle receptacle of the holding portion 23b. At the end of the drive shaft located in the holding section 23b, a gear part, for example in the form of a spur gear 57, is arranged in a rotationally fixed manner. With the one gear part, another gear part in turn is preferably in the form of a spur gear 57 in engagement. The other spur gear 57 is non-rotatably mounted on an axis facing the insertion portion 23a on an axis, which in turn is freely rotatably mounted in a second, formed in the holding portion 23b axle receptacle. At an opposite side, that is, facing away from the insertion section 23a, the other gear part has a recess with a non-circular inner contour. The output shaft of the drive motor 54 has at the free end on an outer contour which is formed substantially complementary to the inner contour of the recess of the other gear part. When inserting the drive motor 54, the output shaft of the drive motor 54 enters into positive engagement with the other transmission part in rotational engagement. Thus, the drive motor 54 is operatively connected via the gear in the holding portion 23b with the spur gear 57 described above. According to an advantageous embodiment of the invention, the other gear part is arranged rotatably on both sides on an axis, so has no recess with a non-circular inner contour. The axle is received freely rotatably mounted on both sides of the other gear part in the second axle receiving the holding portion 23b. At an end facing the drive motor 54, the axle now has a recess analogous to the recess described above with respect to the other gear part, which serves to receive the free end of the output shaft of the drive motor 54. This refinement has the advantage that the axle is not mounted on one side but on both sides of the other gear part in two places, which leads to design advantages.

According to an advantageous development of the invention, the motor holder 23 is designed such that the holding section 23b and possibly the lid 23c have an outer contour corresponding to an outer contour of the guide profile 10, so that the holding section 23b and possibly the lid 23c in the assembled state for a user as part of the leadership profile 10 and thus appear as its continuation.

According to yet another advantageous embodiment of the invention, the motor mount 23 is designed so that the holding portion 23b and possibly the lid 23c have an outer contour which corresponds to an outer contour of the drive profile 20. As a result, the holding section 23b can be regarded as a continuation of the drive profile 20 and, like the drive profile 20, can be accommodated securely in the guide profile 10 and invisibly for the user.

If it is a multi-leaf sliding door, two or more drive modules can be inserted into the guide profile (s) 20. To the Purposes of any necessary synchronization, they can also be interconnected with each other or with a central drive circuit.

FIG. 3D shows a linear drive formed by means of a belt drive. The arrangement is similar to that of FIG. 3A. Instead of a spur gear Kronrad transmission 55, a bevel gear 55 is used in this example. In addition, each rotation axis 56 (and optionally a rotatably arranged with respect to the right guide roller 53 bevel gear 59) is not stored at both ends in side wall portions 22 of the drive profile 20 but in a respective associated holding part 24. The holding parts 24 are preferably fixedly attached to an upper, horizontal wall section 25 of the drive profile 20 or integrally formed therewith. As can be seen in particular on the left in FIG. 3D, each holding part 24, viewed in the ± z coordinate direction, has a cross-sectional shape of a U which is open in the -y coordinate direction. In an interior of the U, a respective deflection roller 53 is arranged freely rotatable. The driver 51 is, as shown in more detail in the bottom right in Figure 3D, provided with a locking device, so that no screws are necessary, which increases the ease of installation and simplifies any replacement.

In the case of the above-described linear drives, a tensioning means tensioning device is preferably provided which advantageously self-tensions to a predetermined extent.

Alternatively, the linear drive can also be formed by means of a chain drive shown in FIG. 3E. In the example shown here, the drive motor 54 is fixed in the motor mount 23 by means of screws. The described spur Krön rad- and bevel gears 55 are interchangeable. In addition, they can be replaced with any other possible gear if the function is retained.

FIGS. 4A-4C show linear drives in the form of a respective spindle drive 60. On the right in the respective figure, a sectional view along the line A - A in Figure 1 is shown. On the left is a sectional view along a respective line E - E ₁ F - F and G - G shown.

A drive motor 64 is accommodated analogously to the linear drives described above in the drive profile 20 or in a motor mount 23. An output shaft of the drive motor 64 is operatively coupled to a threaded spindle 62. The threaded spindle 62 is freely rotatably mounted in a spindle bearing 63. The spindle bearing 63 has, according to an embodiment of the invention shown in Figure 4A on two bearing parts, which are mounted on an inner side of the upper wall portion 25 and in the direction of threaded spindle 62, d. H. in -y coordinate direction in FIG. 4A. The bearing parts each have a passage opening for receiving the threaded spindle 62. The passage openings may have a smooth inner surface.

Alternatively, the through holes are provided with an internal thread into which the threaded spindle 62 is screwed.

Alternatively, as shown on the right in FIG. 4A, a bearing sleeve is fitted in the passage opening, which has an internal thread inside, into which the threaded spindle 62 is screwed. This makes it possible to produce the respective bearing part from a cost-effective material and only to produce the bearing sleeve made of a material suitable for the position tion of the threaded spindle 62 is suitable. Preferably, the bearing sleeve is arranged freely rotatable in the passage opening.

The bearing parts can, as shown in FIG. 4A, be fastened to the horizontal wall section 25, for example by means of screws, or be formed integrally with the drive profile 20.

A driver 61 of a sliding door leaf 1, not shown, also has a passage opening for receiving the threaded spindle 62 and has an internal thread inside, into which the threaded spindle 62 is screwed. The driver 61 may have a bearing sleeve described above with the restriction that the bearing sleeve is arranged rotationally fixed with respect to the driver 61. In addition, the driver on a side facing away from the sliding door 1 end a Laufrol- Ie whose axis of rotation extends in the ± z coordinate direction in Figure 4A. The roller is freely rotatably arranged in the driver so that it rolls on an inner surface of the upper wall portion 25. This serves to avoid bending the threaded spindle 62 in the y-coordinate direction in FIG. 4A in the area of the driver 61.

According to another embodiment of the invention, shown in FIG. 4B, the spindle bearing 63 is formed by means of a bearing part, which has the shape of a stirrup. The bearing part has two threaded spindle receiving portions and a portion which connects the two receiving portions together and is itself attached to the inner surface of the upper wall portion 25 of the drive profile 20.

In order to achieve a higher stability, it is provided according to another variant shown in FIG. 4C that the receiving sections the spindle bearing 63 are also supported on inner sides of the side wall portions 22 of the drive profile 20 and possibly screwed with these.

In FIG. 5A, a linear motor drive integrated into the sliding door suspension of FIG. 1 is shown. A linear motor 2 has a stator 30 and a rotor 40. The stator 30 is formed by means of at least one stator module. Each stator module has a series of coils 33 arranged one behind the other, as seen in the ± x coordinate direction in FIG. 5A, and interconnected according to a predetermined drive scheme. The coils 33 are preferably mounted or attached to associated bobbin 34. Preferably, the bobbin 34 are mounted on a magnetizable yoke body 35 and preferably potted with this to a stator module.

The stator module or modules is or are preferably used in each case a receiving profile which is adapted to be used in the drive profile 20 described above. Ie. Instead of the above-described linear drives as complete modules here only the stator 30 is used as part of the linear motor 2 in the drive profile 20 sets. The receiving profile is preferably designed so that it jams when inserted with the drive profile 20 so that it is securely held. Alternatively, snap-in connections, screw fastenings or all other mounting options are possible.

Alternatively, each stator module is inserted directly into the drive profile 20.

Preferably, the stator modules have a height h _s which is less than a height h _{A of} a receiving space of the drive profile 20 for the stator 30. Ie. above the stator there is a cavity. This Cavity is useful, for example, when viewed in the ± z coordinate direction in FIG. 5A, stator modules of the stator 30 are spaced from each other and accommodating additional components, such as a smoke detector, in a gap thus created between the stator modules should be. Another application is a multi-leaf sliding door. In the case in the drive profile 20, a plurality of stators 30 are housed, which must be driven differently, for example, in terms of their drive direction. Ie. the stators 30 require at least separate control lines. By means of the above-described cavity, it is possible to guide all lines of all stators 30 or stator modules and possibly additional components at one point out of the guide profile 10. This makes it possible to provide a single port at a single point on the sliding door hanger. Thus, a cable duct can be used for all necessary cables, which enormously simplifies cabling.

On the horizontal wall portion 25 opposite ends of the side wall portions 22 close to projections 26, which are parallel to the horizontal wall portion 25 and facing each other. Upper surfaces of the projections 26 form bearing surfaces for the stator 30, the stator 30 thus lies with a bottom on these projections 26.

The rotor 40 belonging to the linear motor 2 is formed by means of one or more rotor parts 41, which, as seen in the ± z-coordinate direction in FIG. 5A, are arranged between roller holders 8 of a respective sliding door leaf 1. Ie. Each rotor 40 is arranged in a space formed between two roller holders 8. In order to prevent caking of the rotor 40 on the stator 30, runner rollers 46 are provided on the rotor parts 41. Advantageously, the rotor rollers 46 are arranged so that they each roll on an underside of one of the projections 26 of the drive profile 20 described above. The projections 26 thus have several functions. First, they serve to support the stator 30 up and the rotor 40 down. On the other hand, in conjunction with the rotor rollers 46, they ensure a predetermined minimum distance between the stator 30 and the rotor 40. In this way, with regard to an interaction between the stator 30 and the rotor 40, a desired operation of the linear motor 2 is made possible. Furthermore, the rotor 40 is guided along the projections 26 and thus along a travel path to be observed. The rotor rollers 46 preferably each have at least one wheel flange for this purpose.

Overall, a very compact and space-saving construction of the linear motor 2 and a simple integration into the above-described guide profile 10 of the sliding door suspension of Figure 1.

According to the embodiment of the invention shown in FIG. 5A, an operative connection in the form of at least one driver designed as a connecting pin 45 is provided between rotor 40 and sliding door leaf 1. The connecting pin 45 is preferably fixedly mounted in a base body 43 of the rotor 40 or used in this example by means of screwing. The connecting pin 45 protrudes from the base body 43 in the direction of the sliding door leaf 1 so far that its free end is arranged below an upper end portion of a mounting portion 47 of the sliding door leaf 1, which mounting portion 47 serves to receive the connecting pin 45. The attachment portion 47 has a receptacle into which the connecting pin 45 engages and thus at a movement of the rotor 40 entrains the sliding door 1. In addition, the receptacle has a depth which is greater than a maximum possible penetration depth of the connecting pin 45 into the receptacle. As a result, the sliding door leaf 1 can move in the ± y coordinate direction to a predetermined extent, without this having a particular effect on the connecting pin 45.

The receptacle is preferably coated on contact surfaces with the connecting pin 45 with an elastic plastic or formed by means of this plastic. As a result, despite constant contact of connecting pin 45 and recording between them a certain game is possible without causing delays between the movement of the rotor 40 and the sliding door leaf 1 and thus a jerky or non-uniform movement of the sliding door leaf 1.

Preferably, the receptacle is further configured such that the sliding door leaf 1 can move in a predetermined degree in the ± z coordinate direction with respect to the connecting pin. For this purpose, the receptacle, seen in the ± y coordinate direction in FIG. 5A, preferably has an oblong-shaped cross section extending in the ± z coordinate direction. Thereby, a transfer of transverse movements of an upper portion of the sliding door leaf 1, d. H. Movements in ± y coordinate direction in Figure 5A, at least attenuated to a predetermined degree.

In FIG. 5A, by way of example, an upper frame part 5 of the sliding door leaf 1 (not shown in more detail) is depicted, once in section and once as a front view. Seen in the direction of its longitudinal extension, the upper frame part 5 in the middle of an attachment portion 47, which preferably has the shape of an O in cross section. At here one Base 43 is fixed at two points in each case a spring member 70 having one end. The spring parts 70 also extend in the direction of the sliding door leaf 1 and are supported on an upper surface of the upper frame part 5.

The spring parts 70 are preferably already in an idle state of the sliding door leaf 1 under bias. The rotor 40 is thus pressed in the direction of the stator 30 due to the spring parts 70. In conjunction with the rotor rollers 46 is ensured that the rotor 40 to the stator 30 has a nearly constant distance, which is required for operation of the linear motor 2. The spring parts 70 further cause any unevenness in the travel of the sliding door leaf 1 and / or other movements of the sliding door leaf 1 as a desired, so to speak "ideal" traversing movement are at least not transferred to the rotor 40 at a considerable extent By means of the rotor 40, the rotor 40 and the sliding door leaf 1 are decoupled as far as possible with respect to undesired movements of the sliding door leaf 1. In addition, an attraction force which is less than a weight force of the rotor 40 is possible between the rotor 40 and the stator 30.

Alternatively or additionally, it is provided that the connecting pin 45 in the base body 43 at least about a ± x coordinate axis in Figure 5A to store pivotable in a predetermined amount. As a result, an easy possibility is created that at least undesired transverse movements of the sliding door leaf 1 are not transmitted to the rotor 40 or only to a very limited extent. If the connecting pin 45 is also pivotably mounted about the ± z coordinate axis, as shown in FIG. 5B, jerking movements of the sliding door leaf 1 in the ± x coordinate direction are at least damped. Furthermore, the rotor 40 takes when starting the Sliding door 1 only after a maximum possible pivoting of the connecting pin 45 with. When braking the rotor 40 is already decelerated before the sliding door 1 is slowed down.

The attachment portion 47 is preferably made of an elastic material. The spring parts 70 rest laterally on the attachment section 47 in such a way that they clamp the attachment section 47 to a predetermined extent and can thus relieve the connection pin 45.

Preferably, according to an embodiment of the invention shown in FIG. 5B, the connecting pin 45 is in the form of a ball on the end received in the main body 43, the outer diameter of which, viewed parallel to the xz plane, is greater than dimensions of at least part of the connecting pin 45, which part likewise is received in the main body 43. This allows pivoting of the connecting pin 45 in each direction of the x-z plane.

In the case of the linear drives 50 based on a traction means 52, normally rigid traction carriers are provided for the operative connection of the traction means 52 with the respective sliding door leaf 1.

Basically, such rigid drivers are also used in the spindle drive 60 and the linear motor 2. In the case of the linear motor 2, a respective carrier 51 is preferably fixedly attached to an underside of the rotor 40 or to a carriage 28.

FIG. 5C shows an operative connection between rotor 40 and sliding door leaves 1 according to another embodiment of the invention. Instead of designed as a leaf or torsion springs spring parts 70 coil springs are used. The main body 43 points downward open receptacles for the coil springs on. Preferably, within each receptacle is a pin-shaped projection which extends in the direction of the sliding door leaf 1. A respective helical spring is plugged into the receptacle and at a base 43 facing the end of a respective projection. At the other end, the coil spring is placed on a connecting element 44 shown at the top right in FIG. 5C. The connecting element 44 is designed such that it is preferably inserted into the respective attachment section 47 by means of clamping action. For this purpose, the attachment portion 47 is formed open to the rotor 40 and has a downwardly widening receptacle. The connecting element 44 has an outer contour that is essentially complementary to an inner contour of the receptacle, wherein its outer dimensions are preferably slightly larger than corresponding inner dimensions of the receptacle. When inserting the attachment portion 47 is spread open and the connecting element 44 is pressed into the receptacle. The connecting portion 44 has at the end facing the coil spring on a spring stop on which the coil spring is supported with its base 43 remote from the end. In addition, the connecting element 44 has a pin-shaped projection analogous to the projection in the receptacle in the main body 43.

For each coil spring, a separate connector 44 may be provided, as shown centrally in Figure 5C. Alternatively, all the connecting elements 44 are integrally formed, as shown on the right in Figure 5C. If the entire connecting element 44 thus formed has a length equal to a length of a receiving space for the connecting element 44, the clamping force of the entire connecting element 44 may be less than in the previously described variant. The connecting element 44 thus strikes at both ends against stop surfaces of the upper frame part 5 or a recess in a full-leaf sliding door 1 and thus takes the sliding door 1 with sure.

In both variants, the spring part 70 additionally assumes a driver function with respect to the sliding door leaf 1.

If no mounting portion 47 is provided, according to a third embodiment of the invention shown in FIG. 5D, it is provided to use the receiving space of the upper frame profile 5 or the full-leaf sliding door leaf 1 itself.

FIG. 5E shows a spring part 70 according to another embodiment of the invention. In a middle section, this spring part 70 has a receptacle 71 for a rotation axis. The respective rotation axis is arranged in a respective main body 43 of a rotor 40 of a linear motor 2 and extends in the ± z coordinate direction. The Achsaufnahme 71 allows easy plugging on an unillustrated axis-shaped part in the main body 43 of a rotor 40 of a linear motor 2. When plugging the axle receiving engages with the respective axis-shaped part and prevents falling of the spring member 70 of the axle-shaped part.

Further, the spring member 70 is made of an elastically deformable material. Free ends of the spring part 70 are supported on an upper surface of a sliding door leaf 1 or an upper frame part 5 analogously to the embodiments described above. Preferably, one end is formed shallower than the other and inserted into a formed on the upper surface of the sliding door leaf 1 or frame part 5 recording. An alternative, shown in Figure 5F spring member 70 according to yet another embodiment of the invention has two legs, which have a support portion 72 on which the spring member 70 is supported. At each support portion 72 is followed in each case in the same direction to a spring portion which is formed by means of a bent leg portion. These leg sections open into a common axle receptacle. An insertion section 73, which is designed such that it is inserted by means of latching into a previously described attachment section 47 and is advantageously locked in it by means of clamping, adjoins a side of the axle receptacle facing away from the leg sections.

A spring part 70 according to an embodiment of the invention shown in FIG. 5G differs from the previous embodiment in that the leg sections do not open into an axle receptacle. Rather, they each have their own axle mount. The axle mounts are aligned in the ± z-coordinate direction. The respective axle receptacle is followed by another leg section in each case. These other leg sections open into the insertion section 73 described above.

Yet another embodiment of spring member 70 is shown in FIG. 5H. The support section 72 is formed by means of a substantially block-shaped part. In the support section 72, an opening for rotationally free receiving one end of a leg spring is formed. The other end of the leg spring is taken out guided in a slot which is formed in the block-shaped part and extends substantially in the direction of its longitudinal extent. In its center, the leg spring preferably forms a passage opening in turn for mounting. Take a rotation axis. Alternatively, the leg spring is supported with this section on the main body 43 of a respective rotor 40.

Figure 6A shows a sliding door hanger according to a second embodiment of the invention in the assembled state. This example is a sliding door leaf 1 having an upper, sloping edge. In the closed state, the sloping edge abuts against a likewise sloping wall 7, as is the case, for example, in walk-in wardrobes in a penthouse. The inclined stop surface for the sliding door 1 is thus a sloping ceiling. The sliding door leaf 1 is guided in the case by means of at least two rollers 6 in a bottom rail 3. The weight of the sliding door leaf 1 is preferably supported at least in part by the rollers 6.

In order to prevent the sliding door leaf 1 from tilting in the ± z coordinate direction in FIG. 6A, a connecting element 44, which may also be formed integrally with the sliding door leaf 1 and extending from the sliding door leaf, is attached to an upper end of the sliding door leaf 1 at the highest corner 1 extends in the direction of the open position of the sliding door leaf 1.

If a traction drive 50 or spindle drive 60 described above is used, a driver 51 is coupled to the respective traction means 52.

If a linear motor 2 itself is to be used as the drive in the sliding door 1 according to FIG. 6A, one of the arrangements described above may be used, in which the linear motor 2 extends along the travel path of the sliding door leaf 1. In that case, for the Li Near motor, seen in the x-coordinate direction in Figure 6A, behind the sliding door 1 in the closed state to provide a space which is a depth greater than or equal to a sum of a length of the rotor 40 and a length of travel of the sliding door leaf 1. This is due to the fact that the rotor 40 is moved along the travel path of the sliding door leaf 1 and comes to rest with an end facing the sliding door leaf 1 at an edge of the sliding door leaf 1 facing the rotor 40.

If the available space is insufficient, an embodiment shown in FIG. 6A is possible. Here, the rotor 40 is arranged in the closed position of the sliding door leaf 1 substantially parallel to a course of the upper edge of the sliding door leaf 1. Furthermore, a carriage 28 of the sliding door leaf 1 is guided guided in at least one horizontally extending guide rail of a right in Fig. 6A drive profile 20. The rotor 40 is attached to a sliding door panel 1 facing the end of the carriage 28. In the closed position of the sliding door leaf 1, the rotor 40 is guided in the direction of its longitudinal extension, for example by means of rotor rollers 46, not shown, on a left-hand drive profile 20 described above. The left drive profile 20 extends at a predetermined distance parallel to the inclined edge of the sliding door leaf 1. In an opening operation of the rotor 40 is moved from a left, housed in the left drive profile 20 stator module to the right in Figure 6A. The rotor 40 thereby gets further and further out of an interaction region of the left stator module. At the same time, it continues to penetrate into an interaction region of the right stator module, which is accommodated in the right-hand drive profile 20. So that the rotor 40 can bridge the angle between the two drive profiles 20, it is flexible. According to an embodiment of the invention shown in FIG. 6B, the rotor 40 consists of individual rotor parts 41. Each rotor part 41 comprises a base body 43 on which a magnetic row 42 is fixedly attached, for example by gluing. At each end to a respective adjacent other rotor part 41 towards each rotor part 41 each have a bearing sleeve. The bearing sleeves extend in a horizontal direction transversely to a longitudinal extension of the rotor 40, ie in ± z coordinate direction parallel to an xz plane in Figure 6A In addition, each bearing sleeve has a length which preferably corresponds to one half of a maximum width dimension of the respective rotor part 41 , Each bearing sleeve is, as seen in the direction of the longitudinal extent of the rotor 40 in the xz plane, with one side of the associated rotor part 40 flush.

It is preferably provided that the two bearing sleeves of a rotor part 40 terminate flush with different sides of the associated rotor part 40. Ie. the bearing sleeves are arranged rotationally symmetrically, so that the respective rotor part 41 in a position and in a position in which it is rotated by 180 ° about the y-coordinate axis in Figure 6A, the same appearance. This offers the advantage that the rotor parts 41 can be connected at both ends with a similar other rotor part.

When assembling two immediately adjacent rotor parts 41, the mutually facing bearing sleeves result in an entire bearing sleeve for an axle, at the ends of which rotor rollers 46 are provided. The rotor rollers 46 are preferably arranged freely rotatable on the associated axis. The axis is characterized executable as a plug-in axis, which is stationary in a respective entire bearing sleeve. Alternatively, the rotor rollers 46 are rotatably mounted on the associated axes, and the axis is freely rotatably mounted freely rotatably in the respective entire bearing sleeve.

In the case of rotor parts 41, which are arranged at the ends of the rotor 40, it is preferably provided that the bearing sleeve facing away from the other rotor parts 41 of the respective end rotor part 41 extends over an entire width of this end rotor part 41. Thus, this bearing sleeve itself forms an entire bearing sleeve.

So that the rotor parts 41 do not cake on one of the stator modules, an arrangement of rotor rollers 46 is preferably provided between each pair of directly adjacent rotor parts 41, as shown in FIG. 6B.

Alternatively, the bearing sleeves can be shaped so that they allow a pivoting immediately adjacent rotor parts 41 only in -y-Koordinaten- direction in Figure 6B, ie downwards. This can be achieved by means of rotor parts 41, which are formed as shown at the bottom right in FIG. 6B. The bearing sleeves have no round outer cross-section but substantially vertically, ie parallel to the yz plane formed, just executed outer walls. With these they are on opposite, parallel walls of the immediately adjacent, facing rotor part 41 at. This means that the respective stator module with sufficient magnetic force, the rotor parts 41, which are located in its interaction region, attracts so that they are aligned with respect to the respective stator module parallel to the xz plane in Figure 6B, a caking so not or only very difficult is possible. In that case, some of the rotor rollers 46 may be omitted, which reduces a rolling friction resistance caused by the rotor rollers 46 on a respective guide rail.

Above the connecting element 44, a carriage 28 is arranged, which is connected by means of a driver, not shown, with the connecting element 44 so that the carriage 28 entrains the sliding door leaf 1 in a movement.

If the weight of the sliding door leaf 1 is completely absorbed by the rollers 6, an arrangement of rollers 21 is not required.

Alternatively, the rotor 40 is provided with a toothing according to an embodiment of the invention of a linear motor 2 shown in FIG. 6C on a side facing the right-hand deflection roller 53. The runner 40 thus has the form of a one-sided rack. The toothing is in engagement with a toothing of the right deflection roller 53 or a spur gear 57, which is arranged non-rotatably with respect to this deflection roller 53.

The stator 30 of the linear motor 2 interacts with a side of the rotor 40 opposite the toothing, on which a magnet row 42 of the rotor 40 is located. An upwards and downwards translational movement of the rotor 40 is thus converted into a rotational movement of the right-hand deflecting roller 53, which then sets the traction means 52 in motion with a driver 51 (not shown) attached thereto.

If there is insufficient space above the sliding door leaf 1 for the runner 40, then according to another embodiment shown in FIG. Order to be provided, the linear motor 2 via a transmission with one of the pulleys 53 wirkzuverbinden.

The stator 30 of the linear motor extends substantially downward from a position of a respective deflection roller 53, d. H. perpendicular to one

Direction of movement of the sliding door leaf 1. coils 33 of the stator 30 are preferably placed on bobbin 34, which in turn can be plugged onto a magnetizable yoke body 35. The stator module formed in this way is preferably cast and inserted into a receiving profile 36.

Furthermore, the receiving profile 36 preferably has guide rails 32 pointing toward the rotor 40. A main body 43 of the rotor 40 preferably has a recess for a magnetic row 42. Alternatively, the main body 43 has a planar surface facing the stator 30, on which the magnet row 42 or its magnet is or are attached, for example by gluing. Laterally of the main body 43, rotor rollers 46 are freely rotatably arranged such that they correspond to the guide rails 32. Advantageously, the guide rails 32 have spherical or concave-shaped running surfaces, whereas the rotor rollers 46 have a running surface complementary to the running surface of the respective guide rail 32.

Alternatively, the running surfaces of the guide rails 32 may be flat. The rotor rollers 46 are formed in the case similar to wheels of rail vehicles. Ie. they have a cross-sectionally flat and with respect to the running surface of the respective guide rail 32 substantially parallel or slightly inclined tread and at least one wheel flange, whereby derailment of the rotor 40 can be prevented. On a side of the rotor facing away from the stator 30 An additional driver 51, which in turn is fastened to a traction means 52, preferably by means of clamping, and is preferably designed analogously to one of the drivers 51 described above, is provided for this purpose. This traction means 52 is folded around two additional deflection rollers 53. The two additional deflection rollers 53 are arranged so that the traction means 52 extends in the region of a travel path of the additional carrier 51 parallel to a longitudinal extent of the rotor 40. An upper of the two additional guide rollers 53 is either formed integrally with the right guide pulley 53 of Figure 2 or rotatably arranged with respect to this.

The additional carrier 51 is preferably arranged so that it comes to lie in a position in which the sliding door 1, not shown, the far left in Figure 6D, near the lower additional guide pulley 53. Furthermore, the additional carrier 51 according to FIG. 6D is preferably arranged at an upper end of the rotor 40. This allows a vertical arrangement of the linear motor 2, seen in the ± x-Co ordinatenrichtung, behind the sliding door 1. This results in a tremendously space-saving arrangement.

The linear drives described above are each designed as a unit or drive module. They have no function with regard to the actual carrying or guiding of a respective sliding door leaf 1. The sliding door leaf 1 is carried separately by means of a guide profile 10, a floor rail 3 or by means of both and guided along its travel path. In this regard, the linear drive is thus decoupled from the sliding door leaf 1.

Figure 7A shows another sliding door system. In addition to a sliding door leaf 1, it has a fixed leaf 80 which is provided with a bottom profile 82 is screwed and in the direction of a guide profile 10 has a side-mounted seal 81. In this example, the entire weight of the sliding door leaf 1 is taken up by rollers 6. Upper guide rollers 21 serve only for laterally guiding the sliding door leaf 1 in its upper edge region in the ± z coordinate direction in FIG. 7A. The guide profile 10 is divided into two and preferably has two identically designed interiors, here once for the sliding door 1 and once for the fixed leaf 80th

In such a guide profile 10 sliding door leaves 1 with any linear drive and inactive leaf 80 are interchangeable used.

Figure 7B shows the sliding door suspension of Figure 7A, provided with two sliding door leaves 1, each provided with a linear motor. The upper frame parts 5 of the frame 4 each have, seen in the ± x-coordinate direction in FIG. 7B, sealing lips 14, which are respectively arranged on an outer side of the upper frame part 5, at least on one outer side of each of the upper frame parts 5. In conjunction with a respective, immediately adjacent arranged side wall portion 12 of the guide profile 10 and outer sides of the rollers 46, a seal in the manner of a labyrinth seal is formed in each case.

A drive profile 20 arranged on the right in FIG. 7B has such a shape that it does not come into positive engagement with any projections in the guide profile 10. So that the drive profile 20 does not fall down, it is fastened by means of indicated fastening screws through the horizontal wall section 13 of the guide profile 10 passing through in a ceiling by means of, for example, dowels. Thus, the fastening screws lock not only the drive profile 20 but also the guide profile 10th In Figure 7C, a sliding door hanger according to yet another embodiment of the invention is shown. The sliding door leaf 1 shown on the right has a lower height than that shown on the left. To compensate for the resulting height difference, the spring member 70 at the left sliding door 1 has a greater height than the right. At the same time, as viewed in the ± x coordinate direction in Fig. 7C, a dimension of respective outer ends of two oppositely disposed rotor rollers 46 is smaller than a width of the receiving space of the upper frame member 5. Thus, it is possible for the rotor rollers 46 to be partially in the receiving space of the upper frame member 5 record. Ie. In spite of the different sliding door leaves, the same linear drive, here in the form of linear motors 2, can be used on both sliding door leaves, their dimensions or positions relative to each other or to the respective drive profile 20 or guide profile 10 remain the same.

For attaching the drive profiles 20 fastening sections are provided, which are arranged biased in the guide profile 10.

Although the invention has been described in connection with a sliding door sash, it is applicable to all other parts traveling along a travel path, such as curved sliding doors, circular sliding doors, bulkhead modules, and the like.
