DETAILED DESCRIPTION

(12) The door illustrated in FIG. 1 comprises a door leaf, denoted as a whole by 10, and a guide web, denoted as a whole by 100, wherein a guide web 100 is provided in each case in the region of both lateral edges of the door leaf, and the door leaf 10 is accommodated between the guide webs. The door leaf 10 consists of a plurality of door leaf members 12 articulated with one another with respect to joint axes extending perpendicularly to the direction extending through the path predetermined by the guide web 100. The guide web 100 has a section 110, which extends approximately in the direction of gravity in parallel to the lateral edges of the door leaf 10 in the closed position, and which merges at its upper end into a spiral-shaped revolving section 120. As indicated in FIG. 1, the door leaf 10 is wound in the open position with the aid of the spiral-shaped section 120 of the guide web 100 into a multilayered coil. Guide rollers 32 and 34 attached to the lateral edges of the door leaf members 12 are provided for guiding the door leaf movement. The guide rollers 32 and 34 form guide roller pairs, between which the guide web 100 is accommodated.

(13) The articulation of the door leaf members 12 is carried out with the aid of joint arrangements having a plurality of joint links 20, wherein each joint link 20 is placed on an end face of a door leaf member 12. The guide rollers 32 and 34 are placed on the joint links 20 or 22, respectively, in such a way that they are arranged on the side of the joint links facing away from the door leaf. The trailing joint link during an opening movement indicated by the arrow P is equipped with a total of four guide rollers 32 and 34, which form two guide roller pairs. The guide rollers of a guide roller pair are spaced apart from one another in a direction perpendicular to the direction extending through the guide web 100, wherein the roller axes extend approximately in parallel to one another. The guide web 100 has outer boundary surfaces or guide surfaces 102 or 104 opposing one another, wherein a first guide roller 32 of each guide roller pair comes into contact on a first guide surface 102 of the guide web 100 and rolls thereon, while a second guide roller 34 of each guide roller pair presses against a second guide surface 104 and rolls thereon. The guide web is thus arranged between the guide rollers 32 and 34 of the individual guide roller pairs.

(14) A bottom seal 14, which presses against the bottom of the wall opening to be closed using the door leaf 10 in the closed position, is arranged on an edge trailing during an opening movement of the door leaf member trailing during the opening movement. As shown in FIG. 1, the guide rollers 32 and 34 of the guide roller pairs can press without play against the guide surfaces 102 and 104 of the guide web.

(15) As can be seen in FIG. 2, guide rollers 32 and 34 are arranged on the two opposing lateral edges of the door leaf 10, which interact with guide webs 100 (not shown in FIG. 2), which are fixedly attached in the region of these lateral edges.

(16) The assembly of a door according to the invention is schematically indicated in FIG. 3. The guide rollers 32 and 34 are rotatably mounted on a common carrier 40 with respect to roller axes extending in parallel to one another and approximately perpendicular to the predetermined path. The roller axes of the guide rollers 32 and 34 are spaced apart from one another in a direction extending perpendicular to the predetermined path and perpendicular to a main plane of the door leaf member. The common carrier 40 has, on its side facing away from the guide rollers 32 and 34, a fastening bolt 42, which extends in a direction extending in parallel to the roller axes and is insertable into a receptacle 44 provided in the region of a joint link 20 placed on an end face of the door leaf member 12. The carrier 40 is held thereon so it is rotatable as a whole with respect to the joint link 20 and the door leaf member 12. The carrier 40 does not have to be locked in the axial direction, because a carrier is provided on each lateral edge of the door leaf member 12 and this carrier 40 is accommodated together with the door leaf member between corresponding, fixed guide webs 100.

(17) To further reduce the axial play, a sliding part 50 is provided, which can be attached to carrier 40 between the guide rollers 32 and 34. In the event of an offset of the entire arrangement, consisting of door leaf member 12, joint link 20, holder 40, and guide rollers 32 and 34, in parallel to the axis of the bolt 42, the sliding part 50 comes into contact on a sliding surface of the guide web 100, which is arranged between the guide surfaces 102 and 104 or connects the guide surfaces 102 and 104 of the guide web 100 to one another.

(18) In FIG. 4, the door leaf member 12 is shown with the carrier 40 in the assembled state.

(19) FIG. 5 shows the door leaf member illustrated in FIGS. 3 and 4 after the assembly between the guide webs 100. It can be seen how the guide roller 32 presses against a guide surface 102 of the guide web 100. The guide roller 34 (also not shown in FIG. 5) presses against the guide surface (not shown) opposing the guide surface 102. The guide web 100 can be accommodated substantially without play between the guide rollers 32 and 34. On the one hand, precise guiding of the door leaf movement is thus achieved and, on the other hand, noise generation is counteracted and the mechanical strain of the guide arrangement is reduced.

(20) The embodiment of the invention illustrated in FIG. 6 essentially differs from the embodiments explained on the basis of FIGS. 1 to 5 in that instead of a roller guide, contactless magnetic guiding of the door leaf movement is provided. For this purpose, the door illustrated in FIG. 6 is equipped with a magnetic guide arrangement 1000, which has door-leaf-side magnetic field generating devices 1010 and web-side magnetic field generating devices 1100. The door-leaf-side magnetic field generating devices are arranged similarly to the guide rollers on opposing sides of the guide web 100. The door-leaf-side magnetic field generating device is formed from permanent magnets, the field lines of which extend inside the magnets themselves in parallel to the door leaf plane. The web-side magnetic field generating device 1100 is also formed from permanent magnets, the field lines of which also extend within the magnets themselves in parallel to the door leaf plane.

(21) The attachment of the permanent magnets is selected so that regions of the same polarization are located opposing and thus repulsive forces act between web-side magnetic field generating device and door-leaf-side magnetic field generating device. The permanent magnets of a single door-leaf-side magnetic field generating device are attached similarly to the guide rollers on a common carrier 1040, so that they are arranged on opposing sides of the guide web and the web-side magnetic field generating device attached thereon. The polarization of the individual permanent magnets can be seen particularly clearly in FIG. 1c). In addition, a lateral positioning magnet 1050 is provided, which is also polarized in such a way that a repulsive force is induced between the door-leaf-side positioning magnet and the web-side magnetic field generating device. The positioning magnet 1050 assumes the same function as the sliding part 50 in the embodiments of the invention explained on the basis of FIGS. 1 to 5. Replacing the positioning magnet with a sliding part is also considered.

(22) In FIG. 6, FIG. 6b) shows the detail indicated in FIG. 6a), FIG. 6c) shows the detail indicated in FIG. 6b), and FIG. 6d) shows a sectional illustration along a plane of section extending perpendicularly to the door leaf movement direction.

(23) The embodiment of the invention illustrated in FIG. 7 essentially differs from the embodiment explained on the basis of FIG. 6 in that the field lines of the individual magnetic field generating devices extend within the permanent magnets in a direction extending perpendicular to the door leaf movement direction. Furthermore, instead of a positioning magnet, a sliding part 50 is provided. In FIG. 7, the same reference numerals are used to identify the individual components of the magnet guide arrangement 1000 as in FIG. 6.

(24) A combination of the contactless magnetic guide according to FIG. 7 with a roller guide according to FIGS. 1 to 5 is illustrated in FIG. 8. A combination of magnet technology and guide roller technology can be advantageous if above-average strains are to be provided, which can be absorbed via the rollers without damage occurring to the magnetic field generating devices. It is also conceivable that the contactless magnet technology is only used in individual sections of the movement path, for example, in the linearly extending sections, while a mechanical support with the aid of the guide rollers 32 and 34 is used in curved sections of the guide path, for example, in the region of the spiral-shaped revolving sections.

(25) In the embodiment of the invention explained on the basis of FIG. 9, the door-leaf-side magnetic field generating device 1010 and the sliding part 50 are designed just as in the embodiment of the invention explained on the basis of FIG. 8. The web-side magnetic field generating device is embodied in the form of an electromagnet arrangement 1200, however. As in the embodiment explained on the basis of FIG. 8, a sliding part 50 is provided as a positioning aid, as is also the case in the embodiment of the invention explained on the basis of FIGS. 1 to 5. During a door leaf movement, the electromagnet arrangement 1200 can be operated with the aid of a suitable control unit so that a repulsive force occurs between electromagnet arrangement and door-leaf-side permanent magnets.

(26) Upon reaching the lower end position, the electromagnet arrangement can either be turned off or operated with reverse polarization. The door leaf is thus displaced in the direction toward a guide web, which is provided in a housing 1300 and is preferably at least partially jacketed by a sealing material, since the floating state generated by the prior polarization of the electromagnet is canceled out. The repulsive forces of the door-leaf-side magnetic field generating device or the door-leaf-side permanent magnets are then sufficient to displace the door leaf. Alternatively, a polarization can be generated using the electromagnet arrangement such that an attractive force is achieved between door-leaf-side permanent magnets and web-side electromagnet arrangement, which generates the desired displacement of the door leaf in a direction extending in the door leaf movement direction.

(27) An improved sealing function can be achieved in the closed state by this displacement of the door leaf, as indicated at 1310 in FIG. 9d). When a door leaf movement is triggered using a suitable control unit, the polarization of the electromagnet arrangement is again switched over such that the floating state is achieved and the door leaf can be guided contactlessly.

(28) The embodiment of the invention illustrated in FIG. 10 essentially corresponds to the embodiment explained on the basis of FIG. 8. It differs from the embodiment explained on the basis of FIG. 8 in that the web-side magnetic field generating devices 1100 are accommodated in a groove extending in the longitudinal direction of the guide, as can be seen particularly clearly in FIGS. 10d) and 10f). It can furthermore be seen that the web-side magnetic field generating devices 1100 protrude somewhat beyond the groove on their side facing away from the groove base. Upon production of the web-side magnetic field generating devices from an elastomer magnet, an additional buffer function can thus be achieved. To ensure satisfactory emergency operation, in the embodiment of the invention illustrated in FIG. 10, guide rollers 32 and 34 are provided on the side of the magnetic field generating devices 1010 and 1100 facing away from the door leaf, similarly as in the embodiment explained on the basis of FIG. 8. Such supplementary mechanical guide devices in the form of guide rollers, guide pins, guide bolts, or the like can be provided in all embodiments of the invention.

(29) Furthermore, it has proven to be particularly advantageous in the scope of the invention if the carriers 1040 for the door-leaf-side magnetic field generating devices 1010 are at least partially formed from a ferromagnetic material, in which the field lines of the magnets arranged on opposing sides of the web-side magnetic field generating device are returned, to thus provide a particularly strong magnetic field in the gap between the opposing door-leaf-side permanent magnets.

(30) As is particularly clearly apparent in FIG. 10e), the web-side magnetic field generating devices, which are preferably formed in the form of so-called elastomer magnets, are also provided in a spiral-shaped revolving section 120 of the guide web 100. Contactless guiding of the door leaf movement can thus also be achieved in the region of the spiral-shaped section, wherein the supplementary mechanical guide devices can be used particularly advantageously in this region.

(31) The invention is not restricted to the embodiment illustrated on the basis of the drawing. Rather, the use of doors according to the invention in the form of so-called sectional doors is also considered, in which the door leaf is arranged overhead approximately in a horizontal plane in the open position. The invention can also advantageously be used in so-called film doors, in which the door leaf consists of plastic films reinforced with the aid of reinforcing profiles. The guide surfaces of the guide web can also enclose an acute angle with one another. The guide rollers can also be fastened directly on the door leaf members without a joint link interconnected if the articulation between the door leaf members is produced with the aid of separate joints. The holders provided in a door according to the invention for the guide rollers can be produced from steel plate, from diecast aluminum, or from milled steel.
