Description

The invention relates to doors having a door leaf capable of movement between an open position, in which it at least partially vacates the wall opening, and a closed position, in which it at least partially closes the wall opening, and a guiding system for guiding movement of the door leaf along at least one section of a given trajectory between the open position and the closed position.

Such doors can be made in the form of so-called sectional doors, in which the door leaf in the open position is located under the ceiling in an approximately horizontal plane. The door leaf of such sectional doors consists of several elements of the door leaf, connected to each other along the hinge axes, passing perpendicular to the given trajectory. This makes it possible to move the door leaf, in which the door leaf passes through an arcuate section of a predetermined trajectory.

In another embodiment of the gate of the type described above, the door leaf in the open position is wound into a multilayer roll. For such roller doors, the door leaf as a whole can be made of a flexible material, such as, for example, a plastic film. To guide the movement of the door leaf, guide rollers can be used, which are mounted on stabilizing devices running perpendicular to the side edges of the door leaf. For this, the stabilizing devices can be connected to hinge systems located in the region of the lateral edges of the door leaf and fixed to the door leaf, which, on the other hand, can be equipped with guide rollers for guiding the movement of the door leaf. Such gates are proposed in EP 3176355 B1. The contents of this publication in relation to the implementation of the door leaf and hinge systems are hereby incorporated by direct reference into this description.

Roller doors, in which the door leaf forms a multi-layer roll over the wall opening, can also be made in the form of so-called fast-moving doors, in which the door leaf, similarly to sectional doors, consists of several elements of the door leaf hinged to each other along hinged axes running perpendicular to the given trajectory, the height of which in the direction of the given trajectory, however, is noticeably less than that of sectional doors. Such gates are described, for example, in DE 102009017767 A1. The contents of this publication in relation to the construction of the door leaf and the articulation of the links of the door leaf are incorporated into this specification by direct reference.

For all gates explained above, to guide the movement of the door leaf, guide rollers are usually used mounted on the door leaf and supported with the possibility of rotation about the axes of the rollers, passing in the closed position perpendicular to the given trajectory and approximately parallel to the plane of the door leaf, which are placed in fixed guide rails, in this case, the course of the guide rails determines the given trajectory. When using the doors just described, in particular at high door leaf speeds, ie with so-called high-speed doors, considerable noise often occurs. Further, there is a large mechanical load on the guide system.

In view of the problems of the prior art described above, the object of the invention is to provide a door that runs at a lower noise level with little wear.

In accordance with the invention, this problem is solved by improving the gate of the above type, which differ essentially in that the guiding system has at least one guide bar, which is stationary relative to the wall opening and extends along a predetermined trajectory, with two outer limiting surfaces and at least two device guides fixed on the door leaf, wherein the first outer limiting surface of the guide bar forms a guide surface for the first guide device, and the second outer limit surface of the guide bar forms a second guide surface for the second guide device.

This invention refers to the discovered fact that the high noise level ascertained in the prior art and the observed mechanical wear can be explained primarily by the fact that when the guide roller is placed in the guide bar, a large clearance must be maintained between the guide roller and the guide bar in order to guarantee trouble-free operation. This, in particular at high door speeds, causes the guide roller to move in a direction perpendicular to the predetermined path, along which the guide roller hits the inner limiting surface of the guide bar. This leads not only to significant noise levels, but also to a correspondingly high mechanical stress on the guide system.

With the gate according to the invention, this drawback is eliminated due to the fact that the guide device does not interact with the inner limiting surfaces of the guide rail, but with the outer limiting surfaces of the guide bar. The corresponding system can be implemented with a significantly smaller gap. In this way, both noise and mechanical wear can be reduced. At the same time, it is taken into account that the direction of movement of the door leaf when using a guide bar having external guide surfaces requires two

- 1 039945 guide devices, respectively, a plurality of guide devices, each of which interacts with the outer guide surface of the guide bar.

In one of the preferred embodiments of the invention, at least one guide device has a guide roller mounted for rotation relative to the roller axis, passing perpendicular to the given trajectory and in the closed position approximately parallel to the door leaf, which, when the door leaf moves, rolls along the guide surface of the door leaf.

A particularly reliable guiding of the door leaf can be achieved when the guide surfaces of the guide bar are arranged approximately parallel to each other and in a direction extending perpendicular to the guide surfaces at a distance from each other. With this arrangement of the guide surfaces, the guide bar can be located between the guide devices, in particular between two guide rollers, when the axes of these rollers are spaced from each other in a direction extending perpendicular to the guide surfaces, and preferably run approximately parallel to each other. In general, this achieves a reliable and almost play-free direction of movement of the door leaf, which helps to reduce noise and wear.

Mounting of the door according to the invention can be simplified while maintaining the required dimensional accuracy, when two guide devices, between which the guide bar is placed in the assembled state and which form a set of guides, are mounted on one common carrier, this common carrier preferably with its side facing away from the guide devices can be detachably installed on the door leaf. This arrangement allows the use of pre-assembled structural units consisting of carrier and guide devices, which can be installed on the door leaf without changing the distance between the guide devices, in particular between the axes of the guide rollers.

When the predetermined trajectory has an arcuate section, in this case it turned out to be particularly expedient if the carrier is mounted on the door leaf with the possibility of rotation about an axis of rotation, if necessary, parallel to the roller axis and / or with the possibility of displacement relative to the axis of translational movement, if necessary, parallel to the roller axis. This can compensate for installation inaccuracies. Such installation can be carried out in a technologically particularly simple way, when, for the installation of a common carrier on the door leaf, a fastening element is made in the form of a fastening pin, extending, if necessary, approximately parallel to the axes of the rollers, and a fastening element in the form of a fastening pin intended for placement, preferably made in the form of a sleeve of the receiving element , wherein one fastener is located on the carrier, and one fastener on the door leaf.

In the doors according to the invention, the movement of the door leaf can be additionally stabilized with a further reduction in noise and mechanical wear, when a slider located between the guide devices, in particular between the axes of guide rollers located on a common carrier, and preferably fixed on a common carrier, is provided, which can be adjacent to the slider located between guide surfaces of the contact surface. In this way, shifting of the door leaf in a direction which, if necessary, runs parallel to the axes of the rollers due to the contact of the slider against the contact surface can be counteracted. To this end, sliders are preferably provided in the region of opposite side edges of the door leaf, which can rest on the sliding surfaces of the guide bars located in the region of these side edges. Then the door leaf is placed between the guide bars, and its movement in the direction passing perpendicular to the given trajectory is prevented, on the one hand, by the guide bars placed between the guide devices, and on the other hand, by the sliders coming into contact with the sliding surfaces of the guide bars.

The invention can be applied with particular advantage to gates in which hinge systems are provided in the region of the edges of the door leaf extending in the closed position approximately in the direction of gravity, each of which has several hinge links hinged to each other along hinge axes running perpendicular to the side edges and approximately parallel to the plane of the door leaf. In this embodiment, at least one, preferably on each hinge link, a carrier having two guide devices can be mounted, so that the guide devices are located on the side of the hinge link facing away from the door leaf, and the guide bar is located between the guide devices. .

The door leaf itself may have several sections of the door leaf hinged to each other along hinge axes running perpendicular to a predetermined trajectory. In this case, the links of the door leaf can be connected to each other by separate hinges. But additionally or alternatively, it is also possible to articulate the links of the door leaf with each other by means of hinge systems installed in the region of the side edges of the door leaf.

The links of the door leaf may have a sheath containing an insulating material, such as, for example, polyurethane foam. The metal sheath can be produced, for example, by cold forming metal strips. The insulating material can be placed between the outer metal shell forming the outer limiting surface of the door leaf link and the inner shell forming the inner limiting surface of the door leaf link. The insulating material may substantially completely fill the cavity between the two shells of the door leaf link.

In addition to or alternatively to the links of the door leaf hinged to each other, the door leaf of the door according to the invention can be made at least in some areas of a flexible material, such as, for example, a plastic film. In this case, the hinge systems can be connected to the hinge systems by means of stabilizing systems extending perpendicular to the side edges of the door leaf, as described in EP 3176355B1.

As already explained above, the invention can be carried out with particular advantage in the case of so-called rolling doors, in which the door leaf forms a multilayer roll in the open position. With such doors, the guide bar has a straight section, preferably extending approximately in the direction of gravity and extending in the closed position approximately parallel to the lateral edges of the door leaf, which at its upper end changes into a spiral section. In this case, two guide strips are expediently provided, located in the region of lateral edges opposite to each other.

The invention also provides for the possibility of non-contact direction of movement of the door leaf of at least one section of a given trajectory in the region of at least one of the side edges of the door leaf. For this purpose, at least one guiding device can have a device for creating a magnetic field located on the door leaf side, and at least one device for creating a magnetic field located on the side of the bar can be matched to the guide bar, these devices for generating a magnetic field designed to obtain a non-contact direction of movement of the door leaf along at least one section of a given trajectory in the region of at least one of the side edges opposite to each other.

At the same time, on opposite sides of the guide bar, which has at least one guide surface, in the area of which a magnetic field is created, interacting devices located on the side of the door leaf for creating a magnetic field can be provided, which can enter either into an attracting or into repulsive interaction with a device located on the side of the bar to create a magnetic field.

Within the scope of the invention, it is possible to guide devices that consist exclusively of suitably activated electromagnets. However, for structural reasons, it has proven to be advantageous if at least one magnetic field generating device, preferably at least one located on the side of the door leaf, i.e. moving together with the door leaf, the magnetic field generating device has at least one permanent magnet. .

In one of the preferred embodiments of the invention, the device for creating a magnetic field located on the door leaf has two permanent magnets located on opposite sides of the guide bar, which are fixed on one common carrier that overlaps the edge of the guide bar located on the side of the door leaf. A particularly reliable non-contact direction can be achieved with this arrangement of the permanent magnets, when the magnetic field lines run inside the permanent magnets fixed on the holder in approximately the same direction and approximately perpendicular to the door leaf, and the carrier at least partially consists of a ferromagnetic material, in particular a magnetically soft material. .

In this case, opposite poles of permanent magnets located on the side of the door leaf, located on opposite sides of the guide bar, face each other. In the gap between opposite poles, a magnetic field is obtained, which can be made particularly strong by the return of the field lines to the ferromagnetic holder. When between the opposite poles of the permanent magnets located on the side of the door leaf, a system for creating a magnetic field is located on the side of the bar, for example, permanent magnets on the side of the bar having the correct polarity, the permanent magnets on the side of the door leaf are repelled in opposite directions from each other permanent magnets on the side of the bar, and a reliable non-contact guidance is achieved. When the door leaf deviates from a predetermined path in a direction perpendicular to the plane of the door leaf, the repulsive forces in the area of at least one permanent magnet located on the side of the door leaf are increased, so that contact between those on the side of the door leaf and those on the side of the door can be effectively counteracted.

- 3 039945 side bar systems for creating a magnetic field.

An additional guarantee of the direction of movement of the door leaf can be achieved if, on the side facing away from the door leaf, the systems for generating the magnetic field located on the side of the door leaf are also provided with guide rollers, guide pins or similar mechanical guide devices which can rest against the guide surfaces. Additional guide rollers can be installed on the door leaf with the possibility of rotation about the axes of the rollers, passing approximately parallel to the door leaf and perpendicular to the given trajectory. In this case, on opposite sides of the guide rail, mechanical guide devices, such as guide rollers, can be arranged, which, when subjected to a particularly strong force in a direction perpendicular to the plane of the door leaf, come into contact with the respective guide surface, whereas with in the desired non-contact direction, they are located at a distance from the guide surfaces. That is, in this arrangement, the guide bar is located, on the one hand, between systems for generating a magnetic field located on the side of the door leaf, and on the other hand, also between mechanical guides mounted on the door leaf, such as, for example, rotatably mounted guides rollers and/or guide pins. In other embodiments of the invention, guide rollers, guide pins or the like can also be arranged on the door leaf side of the door leaf side systems for generating a magnetic field.

Devices for generating a magnetic field located on the side of the bar can be mounted particularly simply when at least one guide surface is provided with a groove extending at least along one section of the predetermined path, in which a device located on the side of the bar can be at least partially placed for creating magnetic field. Moreover, this device for creating a magnetic field located on the side of the bar can be made in the form of a permanent magnet. Particularly advantageous in this arrangement is that the device for generating the magnetic field located on the side of the bar is at least partly made of an elastomeric magnet. An elastomeric magnet is an elastomer in which hard metal materials are embedded. The magnetic field generating device placed in the groove can also protrude from the groove on the side facing away from the bottom of the groove.

With all embodiments of the invention having devices for generating a magnetic field located on the side of the bar and/or located on the side of the door leaf, it has proved expedient if a cleaning device is coordinated with the guide bar and/or the door leaf, while using a cleaning device located on the side of the bar. devices for generating a magnetic field located on the side of the door leaf can be cleaned, and with the help of a cleaning device located on the side of the door leaf, devices for creating a magnetic field located on the side of the bar can be cleaned. The cleaning devices can be in the form of cleaning brushes, for example.

When a predetermined path has a transition between a substantially straight section and a substantially curved section, such as, for example, a transition between a straight section and a helical section, it has proven to be particularly advantageous when a bar-side magnetic field generating device for generating particularly high fields, since in this transitional area, during the movement of the door leaf, particularly high forces arise which, in the non-contact direction, would have to be suppressed by suitably parameterized magnetic field generating devices and their interaction with magnetic field generating devices located on the side of the door leaf. These devices for creating a magnetic field on the side of the bar, which are designed to create particularly large fields, can be, for example, sintered hard magnets.

On the other hand, at least one magnetic field generating device, preferably at least one lath-side magnetic field generating device, can have an electromagnetic system with which the control device is preferably matched.

At the same time, it is also possible to implement a control device for creating a magnetic field wandering along at least one section of a given trajectory. Thus, if necessary, not only the non-contact direction of movement of the door leaf can be carried out, but also a magnetic drive that causes the movement of the door leaf.

Additionally or alternatively, it is also possible to effect an attractive interaction between the magnetic field generating devices by properly activating the electromagnet when the closed position is reached.

In one of the particularly preferred embodiments of the invention, the direction of movement of the door leaf is achieved by means of devices for generating a magnetic field located on the side of the door leaf and located on the side of the bar, which are preferably made in the form of permanent magnets, while electromagnets are additionally provided, which upon reaching the closed position, an attractive interaction is caused with the devices for generating a magnetic field located on the side of the door leaf, so that by switching on the corresponding electromagnets, a sealing function can be created between the door leaf and the frame, respectively, the box. In this case, bistable systems are preferably used, in which the sealing function can also be guaranteed without energizing the electromagnets, while in the second stable position, non-contact guidance by means of permanent magnets without energizing the electromagnets can be guaranteed.

In the method of manufacturing doors with devices for generating a magnetic field, it has proven to be particularly advantageous when magnetized elements, which at least partially consist of a magnetically hard material, are mounted on a guide bar and/or door leaf and only then magnetized. In this way, it is possible to avoid disturbing the installation by the attractive interaction of the permanent magnets with the metal components of the door.

fig. 10 shows a fifth embodiment of a door according to the invention having a magnetic track.

Shown in FIG. 1, the door includes a door leaf, generally indicated by reference 10, and a guide bar, generally indicated by reference 100, whereby one guide bar 100 is provided in the area of the two side edges of the door leaf, and the door leaf 10 is placed between these guide bars. The door leaf 10 consists of several links 12 of the door leaf, hinged to each other along the hinge axes extending in the direction perpendicular to the trajectory given by the guide bar 100 . The guide bar 100 has a section 110 extending parallel to the side edges of the door leaf 10 in the closed position approximately in the direction of gravity, which at its upper end merges into a helical section 120. As shown in FIG. 1, the door leaf 10 is wound into a multi-layered roll by means of the helical section 120 of the guide bar 100 in the open position. To guide the movement of the door leaf, guide rollers 32 and 34 are provided installed on the side edges of the links 12 of the door leaf. These guide rollers 32 and 34 form pairs of guide rollers, between which a guide bar 100 is placed.

The hinged connection of the links 12 of the door leaf is carried out using hinge systems having several hinge links 20, with each hinge link 20 planted on the end surface of one link 12 of the door leaf. The guide rollers 32 and 34 are seated on the hinge links 20, respectively 22, in such a way that they are located on the side of the hinge links facing away from the door leaf. The lagging link in the opening movement indicated by the arrow P is equipped with a total of four guide rollers 32 and 34, which form two pairs of guide rollers. The guide rollers of one pair of guide rollers are spaced apart in a direction extending perpendicularly through the guide bar 100, with the roller axes extending approximately parallel to each other. The guide bar 100 has opposite outer limiting surfaces, respectively guide surfaces 102, respectively 104, wherein the first guide roller 32 of each pair of guide rollers comes into contact with the first guide surface 102 of the guide bar 100 and rolls over it, while the second the guide roller 32 of each pair of guide rollers bears against the second guide surface 104 and rolls over it. So the guide bar is located between the guide rollers 32 and 34 of the individual pairs of guide rollers.

On the lagging edge of the door leaf link lagging during the opening movement, lagging behind during the movement

- 5 039945 opening, there is a floor seal 14, which in the closed position is adjacent to the floor of the wall opening closed by the door leaf 10. As shown in FIG. 1, the guide rollers 32 and 34 of the pairs of guide rollers can rest against the guide surfaces 102 and 104 of the guide bar without play.

As can be seen in Fig. 2, on two opposite side edges of the door leaf 10, guide rollers 32 and 34 are located, which interact with fixedly installed in the area of these side edges, not shown in FIG. 2 guide rails 100.

In FIG. 3 schematically shows the installation of the gate according to the invention. The guide rollers 32 and 34 are mounted on one common carrier 40 with the possibility of rotation about the axes of the rollers, passing parallel to each other and approximately perpendicular to the given trajectory. The axes of the guide rollers 32 and 34 are at a distance from each other in the direction passing perpendicular to the given trajectory and perpendicular to the main plane of the link of the door leaf. The common carrier 40 has, on its side away from the guide rollers 32 and 34, a fastening pin 42, which extends in a direction parallel to the axes of the rollers and can be inserted into a receiving element 44 provided in the region of the hinge link 20 seated on the end surface of the link 12 of the gate. canvases. The carrier 40 is held on it with the possibility of rotation in its entirety relative to the hinge link 20 and link 12 of the door leaf. In the axial direction, the carrier 40 must not stop, because one carrier is provided on each side edge of the door leaf link 12, and these carriers 40, together with the door leaf link, are placed between the corresponding, fixed guide bars 100.

To further reduce the axial clearance, a slider 50 is provided, which can be installed on the carrier 40 between the guide rollers 32 and 34. When the entire system consisting of the link 12 of the door leaf, the hinge link 20, the holder 40 and the guide rollers 32 and 34, the slider 50 comes into contact with the sliding surface of the guide bar 100, which is located between the guide surfaces 102 and 104, respectively, connects the guide surfaces 102 and 104 of the guide bar 100 to each other.

In FIG. 4 shows the door leaf link 12 with carrier 40 in the assembled state.

In FIG. 5 shows the one shown in FIG. 3 and 4 the door leaf link after mounting between the guide bars 100. It can be seen that the guide roller 32 rests on the guide surface 102 of the guide bar 100. The guide surface opposite to the guide surface 102 (not shown) is also adjacent, not shown in FIG. 5 the guide roller 34. The guide bar 100 can be placed between the guide rollers 32 and 34 with practically no gap. Thanks to this, on the one hand, the exact direction of movement of the door leaf is achieved, and on the other hand, noise is counteracted and the mechanical load of the guide system is reduced.

Shown in FIG. 6, the embodiment of the invention differs from the embodiments explained with FIG. 1-5, essentially in that instead of a roller guide, a non-contact magnetic guide for the movement of the door leaf is provided. For this, shown in Fig. 6, the gate is equipped with a magnetic guide system 1000 which has magnetic field generating devices 1010 on the door leaf side and magnetic field generating devices 1100 on the bar side. The devices for creating a magnetic field located on the side of the door leaf are located, similarly to the guide rollers, on opposite sides of the guide bar 100. The device for creating a magnetic field located on the side of the door leaf is made of permanent magnets, the field lines of which run inside the magnets themselves parallel to the plane of the door leaf. canvases. The device 1100 located on the side of the bar for creating a magnetic field is also made of permanent magnets, the field lines of which also run inside the magnets themselves parallel to the plane of the door leaf.

The installation of the permanent magnets is chosen so that areas of the same polarity lie opposite each other, and thus repulsive forces act between the device for creating a magnetic field located on the side of the bar and the device for creating a magnetic field located on the side of the door leaf. The permanent magnets of one separate door leaf-side device for generating a magnetic field, like the guide rollers, are mounted on one common carrier 1040, so that they are located on opposite sides of the guide bar and the device for creating a magnetic field mounted on it, located on the side of the bar. fields. The polarity of the individual permanent magnets is especially clearly visible in FIG. 1c). Additionally, a lateral positioning magnet 1050 is provided, which is also polarized in such a way that a repulsive force is generated between the positioning magnet located on the door leaf side and the device for generating a magnetic field located on the bar side. The positioning magnet 1050 performs the same function as the slider 50 in the embodiments of the invention explained with reference to FIGS. 1-5. It is also possible to replace the positioning magnet with a slider.

In FIG. 6 in FIG. 6b) shows the fragment indicated in FIG. 6a), in Fig. 6c) the fragment indicated in FIG. 6b) and in FIG. 6d) a sectional view along a sectional plane running perpendicular to the direction of movement of the door leaf.

Shown in FIG. 7, the embodiment of the invention differs from the embodiment explained with FIG. 6 essentially in that the field lines of the individual magnetic field generating devices run inside the permanent magnets in a direction perpendicular to the direction of movement of the door leaf. Further, instead of the positioning magnet, a slider 50 is provided. In FIG. 7, the same reference numbers are used to refer to the individual components of the magnetic guide system 1000 as in FIG. 6.

In FIG. 8 shows a combination of the non-contact magnetic guide according to FIG. 7 with a roller guide according to FIG. 1-5. A combination of magnetic technology and guide roller technology may be preferred when extraordinary loads are to be feared, which can be taken up by the rollers without causing damage to the magnetic field generating devices. It is also possible that the non-contact magnetic technology finds application only in certain sections of the trajectory of movement, for example, in straight sections, while the mechanical support by means of guide rollers 32 and 34 finds application in curved sections of the guide path, for example, in the region of spirally twisting sections.

As explained with FIG. 9, the device 1010 located on the side of the door leaf for creating a magnetic field, as well as the slider 50, are made in the same way as in the embodiment of the invention explained with the help of FIG. 8. However, the bar-side magnetic field generating device is in the form of an electromagnetic system 1200. As in the embodiment of the invention explained with reference to FIG. 8, a slider 50 is provided as a positioning aid, as is also the case in the embodiment of the invention explained with reference to FIG. 1-5. When the door leaf moves, the electromagnetic system 1200 can be operated by a suitable control device so that a repulsive force is generated between the electromagnetic system and the permanent magnets on the side of the door leaf.

When the lower end position is reached, the solenoid system can either be switched off or operated with reversed polarity. In this case, the door leaf is displaced in the direction of the guide bar provided in the housing 1300 and preferably at least partially covered with a sealing material, since the suspension created by the former polarity of the electromagnet ceases. Then either the repulsive forces of the device for creating a magnetic field located on the side of the door leaf or of the permanent magnet located on the side of the door leaf are sufficient to displace the door leaf. Alternatively, the polarity can also be generated by means of the electromagnetic system such that an attractive force is achieved between the permanent magnets located on the door leaf side and the electromagnetic system located on the bar side, which creates the desired displacement of the door leaf in a direction perpendicular to the direction of travel of the door leaf.

Due to this displacement of the door leaf in the closed position, an improved sealing function can be achieved, as shown in FIG. 9d) at 1310. When the movement of the door leaf is initiated by the appropriate control device, the polarity of the electromagnetic system is reversed again so that a suspended state is achieved and the door leaf can be guided without contact.

Shown in FIG. 10, the embodiment of the invention corresponds essentially to the embodiment explained with reference to FIG. 8. It differs from the embodiment explained with FIG. 8 in that the bar-side magnetic field generating devices 1100 are placed in a groove extending in the longitudinal direction of the guide bar, as can be seen particularly clearly in FIG. 10d) and 10f). It can also be seen that the magnetic field generation devices 1100 located on the side of the bar protrude somewhat beyond the groove on their side facing away from the bottom of the groove. In the manufacture of devices for generating a magnetic field from an elastomeric magnet located on the side of the bar, an additional buffer function can be achieved in this way. In order to provide a satisfactory emergency movement in the case shown in FIG. 10 embodiment of the invention, similarly to the embodiment explained with FIG. 8, on the side of the magnetic field generating devices 1010 and 1100 away from the gate leaf, guide rollers 32 and 34 are provided. Such additional mechanical guide devices in the form of guide rollers, guide pins, guide pins or the like can be provided in all embodiments of the invention.

Further, within the scope of the invention, it has proven particularly advantageous if the carriers 1040 for the door leaf-side devices 1010 for producing a magnetic field are at least partially made of a ferromagnetic material in which the field lines of the magnets located on opposite sides of the bar-side device to create a magnetic field, are returned so as to ensure a particularly strong magnetic field in the gap between opposite permanent magnets located on the side of the door leaf.

As can be seen especially clearly in FIG. 10e) located on the bar side of the device for creating a magnetic field, which are preferably made in the form of so-called elastomeric magnets, are also provided in the helically twisted section 120 of the guide bar 100. In this way, in the region of the helical section, a non-contact direction of movement of the door leaf can also be achieved, and in In this area, complementary mechanical guides are used with particular advantage.

The invention is not limited to the embodiment shown with the help of the drawings. Moreover, it is also possible to use the doors according to the invention in the form of so-called sectional doors, in which the door leaf in the open position is located under the ceiling in an approximately horizontal plane. The invention can also advantageously be applied to so-called film doors, in which the door leaf consists of plastic films reinforced with reinforcing profiles. The guide surfaces of the guide bar can also form an acute angle with each other. The guide rollers can also be mounted directly on the links of the door leaf without intermediate inclusion of the hinge link, when the hinge connection between the links of the door leaf is carried out by means of separate hinges. The holders for guide rollers provided for the doors according to the invention can be made of sheet steel, die-cast aluminum or milled steel.
