Description

The invention relates to a door with a door leaf that can be moved between an open position, in which it at least partially exposes a wall opening, and a closed position, in which it at least partially closes the wall opening, and a guide arrangement for guiding the movement of the door leaf along at least one section of a predetermined path between the open position and the closed position.

Such gates can be realized in the form of so-called sectional gates, in which the gate leaf is arranged overhead in the open position approximately in a horizontal plane. In such sectional doors, the door leaf consists of a plurality of door leaf elements which are connected to one another in an articulated manner with respect to joint axes running perpendicularly to the predetermined path. This enables a door leaf movement in which the door leaf runs through an arcuate section of the specified path.

In another embodiment of gates of the type described above, the gate leaf is wound up into a multi-layer coil in the open position. In the case of such roller doors, the door leaf can be formed entirely from a flexible material, such as a plastic film. To guide the movement of the door leaf, guide rollers can be used, which are attached to stabilizing devices running perpendicularly to the lateral edges of the door leaf. For this purpose, the stabilizing devices can be coupled to joint arrangements arranged in the area of the lateral edges of the door leaf and fastened 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 in the EP 3 176 355 B1 specified. The disclosure content of this document with regard to the design of the door leaf and the joint arrangements is hereby incorporated into this description by express reference.

Roller doors, in which the door leaf forms a multi-layer roll above the wall opening in the open position, can also be implemented in the form of so-called high-speed doors, in which the door leaf is articulated, similar to sectional doors, from a plurality of articulated axes running perpendicular to the specified path There are door leaf elements, the height of which in the direction of the given track is, however, significantly lower than in the case of sectional doors. Such goals are for example in the DE 10 2009 017 767 A1 described. The disclosure content of this document is hereby included in this description with regard to the construction of the door leaf and the articulated connection of the door leaf elements by express reference.

In all the doors explained above, to guide the movement of the door leaf, guide rollers are usually attached to the door leaf and rotatably mounted with respect to the roller axes running perpendicular to the specified path and approximately parallel to the plane of the door leaf in the closed position and are accommodated in fixed guide rails, with the course of the Guide rails determines the given path. When the doors just described are used, considerable noise is often generated, particularly at high speeds of door leaf movement, that is to say in the case of so-called high-speed doors. Furthermore, a large mechanical stress on the guide arrangement is observed.

In view of the above-described problems in the prior art, the invention is based on the object of providing low-wear movable gates with low noise development.

According to the invention, this object is achieved by a further development of doors of the type mentioned at the beginning, which is essentially characterized in that the guide arrangement has at least one guide web which is arranged fixed with respect to the wall opening and extends along the predetermined path and has two outer boundary surfaces and at least two on the door leaf has fixed guide devices, wherein a first outer boundary surface of the guide bar forms a guide surface for a first guide device, and the second outer boundary surface of the guide bar forms a second guide surface for a second guide device.

This invention is based on the finding that the high level of noise development found in the prior art and the observed mechanical wear is primarily due to the fact that when a guide roller is accommodated in a guide rail, to ensure trouble-free operation, there is a large amount of play between the guide roller and the guide rail must become. Particularly at high door travel speeds, this leads to a movement of the guide roller in a direction perpendicular to the predetermined path, in the course of which the guide roller strikes the inner boundary surfaces of the guide rail. This not only leads to a considerable amount of noise, but also to a correspondingly high mechanical load on the guide arrangement.

In the case of doors according to the invention, this deficiency is eliminated in that the guide device does not interact with the inner delimiting surfaces of a guide rail, but with the outer delimiting surfaces of a guide bar. A corresponding arrangement can be carried out with significantly less play. In this way, both the noise development and the mechanical wear can be reduced. It is accepted that guiding the movement of the door leaf when using a guide bar with outer guide surfaces requires two guide devices or a large number of guide devices, each of which interacts with an outer guide surface of the guide bar.

In a preferred embodiment of the invention, at least one guide device has a guide roller which is rotatably mounted with respect to a roller axis running perpendicular to the predetermined path and approximately parallel to the door leaf in the closed position and which rolls on a guide surface of the door leaf when the door leaf moves.

The door leaf movement can be guided particularly reliably if the guide surfaces of the guide web are arranged approximately parallel to one another and at a distance from one another in a direction running perpendicularly to the guide surfaces. With this arrangement of the guide surfaces, the guide web can be arranged between the guide devices, in particular between two guide rollers, if their roller axes are spaced apart from one another in a direction perpendicular to the guide surfaces and preferably run approximately parallel to one another. Overall, a reliable and almost play-free guidance of the door leaf movement is achieved, which contributes to reducing noise and wear.

The assembly of goals according to the invention can be simplified while maintaining the required dimensional accuracy if two guide devices, which in the assembled state receive the guide web between them and form a guide set, are mounted on a common carrier, the common carrier preferably being detachable on its side facing away from the guide devices can be attached to the door leaf. This arrangement enables the use of pre-assembled assemblies, consisting of carrier and guide devices, which can be attached to the door leaf without changing the distance between the guide devices, in particular between the roller axes of the guide rollers.

If the specified path has an arcuate section, it has proven to be particularly expedient in this case if the carrier can be rotated with respect to an axis of rotation that may run parallel to the roller axes and/or displaceable with respect to a translation axis that may run parallel to the roller axis on the door leaf is attached. This allows assembly inaccuracies to be compensated. Such an attachment can be realized in a particularly simple manner in terms of production technology if, for attaching the common carrier to the door leaf, a fastening element in the form of a fastening bolt possibly extending approximately parallel to the roller axes and a fastening element in the form of a fastening bolt designed to receive the fastening bolt, preferably in the form of a sleeve running recording is carried out, wherein a fastening element is arranged on the carrier and a fastening element on the door leaf.

In the case of doors according to the invention, the movement of the door leaf can be further stabilized, with a further reduction in noise and mechanical wear, if a sliding piece is provided which is arranged between the guide devices, in particular between the roller axes of the guide rollers arranged on the common support and is preferably fastened to the common support a sliding surface of the guide web arranged between the guide surfaces can be applied. In this way, an offset of the door leaf in a direction possibly running parallel to the roller axes can be counteracted by the sliding piece resting against the contact surface. For this purpose, sliding pieces are preferably provided in the area of the opposite lateral edges of the door leaf, which can be placed on sliding surfaces of the guide webs arranged in the area of these lateral edges. The door leaf is then accommodated between the guide webs and is prevented from moving in a direction running perpendicularly to the predetermined path on the one hand by the mechanisms accommodated between the guide devices Guide webs and on the other hand prevented by the sliding pieces coming into contact with the sliding surfaces of the guide webs.

The invention can be used with particular advantage in doors in which articulation arrangements are provided in the area of the lateral edges of the door leaf running approximately in the direction of gravity in the closed position, each of which has a plurality of articulation axes running perpendicularly to the lateral edges and approximately parallel to the plane of the door leaf has articulated interconnected joint members. In this embodiment, a carrier with two guide devices can be attached to at least one, preferably to each joint member such that the guide devices are arranged on the side of the joint member facing away from the door leaf and the guide web is arranged between the guide devices.

The door leaf itself can have a plurality of door leaf elements connected to one another in an articulated manner with respect to joint axes running perpendicularly to the predetermined path. The door leaf elements can be connected to one another via separate joints. In addition or as an alternative, however, it is also conceivable to connect the door leaf elements to one another in an articulated manner with the aid of the joint arrangements attached in the area of the lateral edges of the door leaf.

The door leaf members may have a shell containing an insulating material such as polyurethane foam. The metal shell can be produced, for example, by cold forming metal strips. The insulating material may be sandwiched between an outer metal shell forming an outer perimeter of the door leaf member and an inner shell forming an inner perimeter of the door leaf member. The insulating material can essentially completely fill the cavity between the two shells of the door leaf member.

In addition or as an alternative to the door leaf members that are connected to one another in an articulated manner, the door leaf of the doors according to the invention can be formed at least in sections from a flexible material, such as a plastic film. In this case, the joint arrangements can be coupled to the joint arrangements via stabilizing arrangements running perpendicularly to the lateral edges of the door leaf, as in FIG EP 3 176 355 B1 specified.

As already explained above, the invention can be implemented with particular advantage in so-called roller doors, in which the door leaf in the open position multi-layer winding forms. In gates of this type, the guide bar has a rectilinear section that preferably runs approximately in the direction of gravity and in the closed position extends approximately parallel to the lateral edges of the door leaf, which transitions at its upper end into a spirally circumferential section. In this case, two guide webs arranged in the region of the mutually opposite lateral edges are expediently provided.

Within the scope of the invention, consideration is also given to guiding the door leaf movement in a non-contact manner at least in a section of the specified path in the area of at least one of the lateral edges of the door leaf. For this purpose, at least one guide device can have a magnetic field generating device on the door leaf side and at least one magnetic field generating device on the web side can be assigned to the guide bar, with the magnetic field generating devices being designed to obtain contact-free guidance of the door leaf movement along at least one section of the specified path in the area of at least one of the opposite lateral edges.

Cooperating magnetic field generating devices on the door leaf side can be provided on opposite sides of the guide web with at least one guide surface in the area of which a magnetic field is generated.

Within the scope of the invention, guide devices are envisaged that consist exclusively of electromagnets that can be controlled in a suitable manner. For design reasons, however, it has proven to be advantageous if at least one magnetic field generating device, preferably at least one magnetic field generating device on the door leaf side, ie movable with the door leaf, has at least one permanent magnet.

In a preferred embodiment of the invention, the magnetic field generation device on the door leaf side has two permanent magnets which are arranged on opposite sides of the guide web and are fixed to a common carrier that engages over an edge of the guide web on the door leaf side. A particularly reliable non-contact guidance can be achieved with this arrangement of permanent magnets if the magnetic field lines within the permanent magnets fixed to the holder run 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 soft magnetic material.

Opposite poles of the permanent magnets on the door leaf side, which are arranged on opposite sides of the guide web, face each other. A magnetic field is obtained in the gap between the opposite poles, which can be made particularly strong by returning the field lines to the ferromagnetic holder. If a web-side magnetic field generation arrangement, such as web-side permanent magnets with suitable polarity, is arranged between the opposite poles of the permanent magnets on the door leaf side, the permanent magnets on the door leaf side are repelled in opposite directions from the permanent magnets on the web side and reliable non-contact guidance is achieved. If the door leaf is deflected from the specified path in a direction perpendicular to the plane of the door leaf, the repulsive forces in the area of at least one permanent magnet on the door leaf increase, so that the contact between the magnetic field generation arrangements on the door leaf and web side can be counteracted effectively.

The guidance of the door leaf movement can be further safeguarded if guide rollers, guide pins or similar mechanical guide devices that can be placed on the guide surfaces are also arranged on the side of the magnetic field generating arrangements on the door leaf side facing away from the door leaf. Additional guide rollers can be rotatably mounted on the door leaf with respect to roller axes running approximately parallel to the door leaf and perpendicular to the predetermined path. Mechanical guide devices, such as guide rollers, can be arranged on opposite sides of the guide web, which come into contact with the corresponding guide surface when a particularly large force is applied in a direction running perpendicular to the plane of the door leaf, while they move at a distance from the Guide surfaces are arranged. In this arrangement, the guide web is arranged on the one hand between the magnetic field generation arrangements on the door leaf side and on the other hand also between the mechanical guide devices attached to the door leaf, such as the rotatably mounted guide rollers and/or the guide pins. In other embodiments of the invention, the guide rollers, guide pins or the like can also be arranged on the side of the magnetic field generating devices on the door leaf side that faces the door leaf.

The web-side magnetic field generating devices can be installed particularly easily if a groove is provided in at least one guide surface that extends at least along a section of the predetermined path and in which a web-side magnetic field generating device can be at least partially accommodated. The web-side magnetic field generation device can be designed as a permanent magnet. In this arrangement, it is particularly advantageous if the magnetic field generating device on the web side is formed at least partially from an elastomer magnet. An elastomer magnet is an elastomer in which hard magnetic materials are embedded. The magnetic field generating device accommodated in the groove can also protrude out of the groove on the side facing away from the groove bottom.

In all embodiments of the invention with magnetic field generating devices on the web side and/or the door leaf side, it has proven to be expedient if a cleaning device is assigned to the guide web and/or the door leaf, with the cleaning device on the web side being able to clean the magnetic field generating devices on the door leaf side, and the cleaning device on the door leaf side being able to clean the web-side magnetic field generating devices can be cleaned. The cleaning devices can be implemented, for example, in the form of cleaning brushes.

If the predetermined path has a transition between a substantially rectilinear section and a substantially curved section, such as a transition between a rectilinear section and a helical circumferential section, it has proven to be particularly expedient if in the region of this transition a magnetic field generating device on the web side is provided for generating particularly large fields, because particularly large forces occur in this transition area during the movement of the door leaf, which should be absorbed in the sense of contact-free guidance by appropriately dimensioned magnetic field generating devices and their interaction with the magnetic field generating devices on the door leaf side. The web-side magnetic field generating devices designed to generate particularly large fields can be sintered hard magnets, for example.

On the other hand, at least one magnetic field generating device, preferably at least one web-side magnetic field generating device, can have an electromagnet arrangement, which is preferably assigned a control device.

It is also contemplated that the control device should be designed to generate a magnetic field that travels along at least one section of the specified path. In this way, not only contact-free guidance of the movement of the door leaf can be implemented, but also a magnetic drive that effects the movement of the door leaf.

In addition or as an alternative, consideration is also given to bringing about an attractive interaction between the magnetic field generating devices by suitably controlling the electromagnet when the closed position is reached.

In a particularly preferred embodiment of the invention, the door leaf movement is guided with magnetic field generating devices on the door leaf and web side, which are preferably realized by permanent magnets, with additional electromagnets being provided which, when the closed position is reached, cause an attractive interaction with the magnetic field generating devices on the door leaf, so that by switching on of the corresponding electromagnets, a sealing function can be produced between the door leaf and a frame or frame. Bistable arrangements are preferably used in which the sealing function can also be ensured without energizing the electromagnets, while in the second stable position non-contact guidance can be ensured with the aid of the permanent magnets without energizing the electromagnets.

In a method for manufacturing a door with magnetic field generating devices, it has proven to be particularly expedient if magnetized elements, which at least partially consist of hard magnetic material, are attached to the guide bar and/or the door leaf and only then magnetized. This avoids disruption to the installation due to the attractive interaction of the permanent magnets with the metal components of the door.

This in 1 The gate shown comprises a gate leaf, generally designated 10, and a guide web, generally designated 100, with a guide web 100 being provided in the region of both lateral edges of the door leaf, and the door leaf 10 being accommodated between the guide webs. The door leaf 10 consists of a plurality of door leaf elements 12 which are connected to one another in an articulated manner with respect to a joint axis running perpendicularly to the direction specified by the guide bar 100. The guide bar 100 has a section which runs parallel to the lateral edges of the door leaf 10 in the closed position, approximately in the direction of gravity 110, which merges into a spirally encircling section 120 at its upper end. As in 1 indicated, the door leaf 10 is wound up in the open position with the aid of the spiral-shaped section 120 of the guide bar 100 to form a multi-layer coil. Guide rollers 32 and 34 are provided on the lateral edges of the door leaf members 12 to guide the movement of the door leaf. The guide rollers 32 and 34 form pairs of guide rollers between which the guide bar 100 is accommodated.

The articulated connection of the gate leaf members 12 takes place with the aid of a plurality of joint members 20 having joint arrangements, each joint member 20 on a Face of a door leaf member 12 is placed. The guide rollers 32 and 34 are placed on the joint members 20 and 22, respectively, in such a way that they are arranged on the side of the joint members facing away from the door leaf. The articulated member that follows 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 a pair of guide rollers are spaced apart from one another in a direction perpendicular to the direction running through the guide bar 100, with the roller axes running approximately parallel to one another. The guide web 100 has opposite outer boundary surfaces or guide surfaces 102 and 104, with a first guide roller 32 of each pair of guide rollers coming into contact with a first guide surface 102 of the guide web 100 and rolling thereon, while a second guide roller 34 of each pair of guide rollers on a second guide surface 104 rests and rolls on it. The guide web is arranged between the guide rollers 32 and 34 of the individual pairs of guide rollers.

A bottom seal 14 is arranged on the edge of the gate leaf element that trails behind during an opening movement. As in 1 shown, the guide rollers 32 and 34 of the pairs of guide rollers can bear against the guide surfaces 102 and 104 of the guide bar without play.

As in 2 as can be seen, guide rollers 32 and 34 are arranged on the two opposite lateral edges of the door leaf 10, which are fixed in the area of these lateral edges in 2 guide webs 100, not shown, interact.

In 3 the assembly of a gate according to the invention is indicated schematically. The guide rollers 32 and 34 are rotatably mounted on a common carrier 40 with respect to roller axes running parallel to one another and approximately perpendicular to the predetermined path. The roller axes of the guide rollers 32 and 34 are spaced from each other in a direction perpendicular to the predetermined path and perpendicular to a principal plane of the door leaf member. On its side facing away from the guide rollers 32 and 34, the common support 40 has a fastening bolt 42, which extends in a direction parallel to the roller axes and can be inserted into a receptacle 44 provided in the region of a joint member 20 placed on an end face of the door leaf member 12 . The carrier 40 is held thereon in a generally rotatable manner with respect to the hinge member 20 and the door leaf member 12 . In the axial direction, the carrier 40 does not have to be locked because a bracket is provided on each lateral edge of the door leaf member 12 and these brackets 40 are received together with the door leaf member between respective fixed guide webs 100.

To further reduce the axial play, a sliding piece 50 is provided, which can be attached to the carrier 40 between the guide rollers 32 and 34 . When the overall arrangement, consisting of door leaf element 12, articulated element 20, holder 40 and guide rollers 32 and 34, is offset parallel to the axis of bolt 42, sliding piece 50 comes into contact with a sliding surface of guide web 100, which is arranged between guide surfaces 102 and 104 is, or the guide surfaces 102 and 104 of the guide bar 100 connects to each other.

In 4 the door leaf member 12 is shown with the carrier 40 in the assembled state.

figure 5 shows that in the Figures 3 and 4 shown gate leaf element after assembly between the guide webs 100. It can be seen how the guide roller 32 bears against a guide surface 102 of the guide web 100. On the guide surface (not shown) opposite the guide surface 102 is the in figure 5 guide roller 34, also not shown. The guide web 100 can be accommodated between the guide rollers 32 and 34 largely without play. On the one hand, this achieves precise guidance of the door leaf movement and, on the other hand, counteracts the development of noise and reduces the mechanical load on the guide arrangement.

In the 6 illustrated embodiment of the invention differs essentially from the basis of Figures 1 to 5 Explained embodiments that instead of a roller guide, a non-contact magnetic guide of the door leaf movement is provided. This is in 6 The door shown is equipped with a magnetic guide arrangement 1000, which has magnetic field generating devices 1010 on the door leaf side and magnetic field generating devices 1100 on the web side. Similar to the guide rollers, the magnetic field generating devices on the door leaf side are arranged on opposite sides of the guide web 100 . The magnetic field generating device on the door leaf side is formed from permanent magnets, the field lines of which run parallel to the plane of the door leaf within the magnets themselves. Likewise, the magnetic field generating device 1100 on the web side is formed from permanent magnets, the field lines of which also run within the magnets themselves parallel to the plane of the door leaf.

The attachment of the permanent magnets is selected in such a way that areas of the same polarity are opposite one another and thus repelling forces act between the magnetic field generating device on the web side and the magnetic field generating device on the door leaf side. The permanent magnets of an individual magnetic field generating device on the door leaf side are attached to a common carrier 1040, similar to the guide rollers, so that they are arranged on opposite sides of the guide web and the web-side magnetic field generating device attached thereto. The polarity 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 poled in such a way that a repulsive force is produced between the positioning magnet on the door leaf side and the magnetic field generating device on the web side. The positioning magnet 1050 performs the same function as the slider 50 in the basis of Figures 1 to 5 illustrated embodiments of the invention. Replacing the positioning magnet with a slider is also being considered.

In 6 shows Figure 6b ) this in Figure 6a ) marked detail, Figure 6c ) this in Figure 6b ) marked detail and Figure 6d ) a sectional view along a sectional plane running perpendicular to the direction of movement of the door leaf.

In the 7 illustrated embodiment of the invention essentially differs from the reference 6 Explained embodiment that the field lines of the individual magnetic field generating devices run within the permanent magnets in a direction perpendicular to the direction of movement of the door leaf. Furthermore, a slider 50 is provided instead of a positioning magnet. In 7 the same reference numbers are used to designate the individual components of the magnet guide arrangement 1000 as in FIG 6 .

In 8 is a combination of non-contact magnetic guidance according to 7 with a roller guide according to Figures 1 to 5 shown. A combination of magnet technology and guide roller technology can be advantageous if there are concerns about above-average loads that can be absorbed by the rollers without damaging the magnetic field generating devices. It is also conceivable that the non-contact magnetic technology is only used in individual sections of the movement path, such as in the straight sections, while mechanical support using the guide rollers 32 and 34 in curved sections of the Guideway, such as in the area of the spirally encircling sections is used.

When using the 9 Explained embodiment of the invention, the magnetic field generating device 1010 on the door leaf side and the slider 50 are designed in the same way as in the case of the reference to FIG 8 illustrated embodiment of the invention. However, the magnetic field generation device on the web side is designed in the form of an electromagnet arrangement 1200 . Just like with the based on the 8 illustrated embodiment, a slider 50 is provided as a positioning aid, as is also the case with the basis of Figures 1 to 5 illustrated embodiment of the invention is the case. When the door leaf moves, the electromagnet arrangement 1200 can be operated with the aid of a suitable control device in such a way that a repulsive force occurs between the electromagnet arrangement and the permanent magnets on the door leaf side.

When the lower end position is reached, the electromagnet arrangement can either be switched off or operated with reversed polarity. As a result, the door leaf moves in the direction of a guide web provided in a housing 1300 and preferably at least partially encased by a sealing material, since the state of levitation created by the previous polarity of the electromagnet is eliminated. Either the repulsive forces of the magnetic field generating device on the door leaf side or of the permanent magnets on the door leaf side are then sufficient to move the door leaf. Alternatively, the electromagnet arrangement can also be used to generate such a polarity that an attractive force is achieved between the permanent magnets on the door leaf and the electromagnet arrangement on the web side, which generates the desired displacement of the door leaf in a direction running in the direction of movement of the door leaf.

By shifting the door leaf in this way, an improved sealing function can be achieved when it is closed, as shown in Figure 9d ) indicated at 1310. If a door leaf movement is triggered with a suitable control device, the polarity of the electromagnet arrangement is reversed again so that the floating state is achieved and the door leaf can be guided without contact.

In the 10 illustrated embodiment of the invention corresponds essentially to the basis of 8 illustrated embodiment. It differs from that based on the 8 explained embodiment that the web-side magnetic field generating devices 1100 received in a longitudinal direction of the guide bar extending groove are, as particularly evident in the Figure 10d ) and 10f ) recognizable. It can also be seen that the web-side magnetic field generating devices 1100 protrude slightly beyond the groove on their side facing away from the groove bottom. When the web-side magnetic field generating devices are made from an elastomer magnet, an additional buffer function can be achieved in this way. To ensure satisfactory emergency operation, the in 10 illustrated embodiment of the invention similar to that based on in 8 embodiment explained on the side facing away from the door leaf of the magnetic field generating devices 1010 and 1100 guide rollers 32 and 34 are provided. 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.

Furthermore, it has proven to be particularly advantageous within the scope of the invention if the supports 1040 for the magnetic field generating devices 1010 on the door leaf side are formed at least partially from a ferromagnetic material, in which the field lines of the magnets arranged on opposite sides of the web-side magnetic field generating device are fed back, so as to to provide a particularly strong magnetic field in the gap between the opposing permanent magnets on the door leaf.

As is particularly evident in Figure 10e ) can be seen, the web-side magnetic field generating devices, which are preferably in the form of so-called elastomer magnets, are also provided in a spirally encircling section 120 of the guide web 100 . In this way, contact-free guidance of the door leaf movement can also be achieved in the area of the spiral-shaped section, with the additional mechanical guide devices being used with particular advantage in this area.

The invention is not limited to the embodiment shown in the drawing. Rather, the use of doors according to the invention in the form of so-called sectional doors is also contemplated, in which the door leaf is arranged overhead in the open position approximately in a horizontal plane. The invention can also be used to advantage in so-called foil gates in which the gate leaf consists of plastic foils 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 attached directly to the gate leaf members without the interposition of a joint member if the articulated connection between the gate leaf members using separate joints takes place. The holders provided for the guide rollers in a door according to the invention can be made of sheet steel, die-cast aluminum or milled steel.
