Abstract

The folding door for a building has a drive (40) on the exterior of the faces of at least two door panels (18) in the area of the movement guide (28) and operable parallel to it. It acts on the hinge connector (24) between the door panels. Both door panels are thus guided during their opening and closing movement.

Description

The invention relates to a folding door according to the preamble of claim 1.

Folding gates with at least one gate wing, which in turn consists of at least two gate segments, which over one Hinge connection pivotally connected to each other are as an alternative to normal swing gates or Roller shutters used to cover a door opening and thus to close or to release them.

Advantages of folding gates over wing gates or roller gates are among other things that with them also great Allow the gate openings to span, with the individual folded Gate segments with the gate open in the area of side vertical gate edge or in a double leaf Version in the area of the two vertical door edges take up little space. In contrast to swing gates folding doors do not have wide spans when open side gate wing, which for example when driving through can represent an obstacle to traffic. In contrast to roll gates need folding doors in the area of the upper horizontal Torrandes does not take up too much space, which is caused by rolling gates that in the open Condition of the gate must be recorded. Finally, with folding gates, the individual gate segments be better matched to the structural conditions and also consist of glass.

Folding gates and drives for this are from the state of the art Technology known in a variety of embodiments. So shows for example DE-OS-26 18 179 with a folding gate Articulated drive, which consists of at least two gate leaves is formed gate segments, the two gate segments via a hinge connection relative to each other are designed to be foldable. The drive with which the two Gate segments angled to each other or folded in to open the gate and with which the both door segments can be brought into an extended position, so that the gate opening is closed and the segments arranged essentially in line are arranged in the form of two in the gate segments Hydraulic cylinders formed, the piston rods over a joint system is thus articulated on the two door segments are that when the piston rods extend from the cylinders the two door segments are angled towards each other. One disadvantage of this is that per pair of door segments such a drive device consisting of two hydraulic cylinders must be provided so that at larger gate wings, for example, from four, five or there are six gate segments, the entire drive and also whose control becomes complex. Furthermore prohibits due to the arrangement of the drive device within of the door segments, their design in transparent or transparent, otherwise the drive device would be disruptively visible.

EP-OS 0 794 310 shows a folding wing door, which in illustrated embodiment with two gate leaves there are two gate segments each. The drive of each Gate wing or gate segments takes place via one at the top built-in reversible rope or horizontal gate edge Chain drive that attacks on carriages, which each outermost, that is to say the door segments facing the center of the door carry in an upper horizontal guide. This is probably one of the most common construction methods of a folding door represents.

From DE-PS 38 43 174 is a drive for a folding door become known, the one in the middle of the gate opening in central drive box arranged at the upper horizontal gate edge has, each via a push rod joint drives a gate wing consisting of two gate segments. The disadvantage here is particularly the unsightly expansive construction with the push rods, which have a high Need space.

DE-OS 38 31 963 shows a folding door with several Wing pairs in which the opening and closing process or the folding movements of the individual door segments a complex backdrop control is carried out.

A folding door according to the preamble of claim 1 known from DE-PS 28 40 074. This well known Folding door is made up of several rigid door segments, which are articulated by means of hinges, the Hinges on the respective door segment on opposite Sides attached to its median plane and being the Folding door can be brought into an open position in which the Gate segments lie essentially flat on one another and can be brought into a closed position in which the door segments form a plane and their narrow sides together lie, with a guide for the door segments is provided and a drive device is present, with which the individual gate segments around their hinges are pivotable to from the open position to the closed position and to be movable back again. At least every second gate segment is centered on its upper one horizontal edge on a horizontal guide device, for example suspended from a rail. For one clean opening and especially closing movement is one end guide provided on the floor and / or the ceiling, into which the outermost free gate segment enters, so that the individual gate segments from the adjacent or kinked position according to the full or partial open position can be transferred to the extended position, which corresponds to the closed position of the folding door. Thanks to this ceiling and / or bottom-side guidance, the folding door is in accordance DE-PS 28 40 074 complex in its construction. Disadvantageous is also the suspension of every second gate segment on the ceiling-side guide. Finally remains silent DE-PS 28 40 074 both on the type and arrangement or the point or points of attack of the drive.

In contrast, the present invention Task made, starting from DE-PS 28 40 074 one new type of folding door with improved functional properties, high reliability and attractive design.

The present invention proposes to achieve this object according to claim 1 before that the drive for the gate wing of the folding gate essentially outside of the surfaces of the gate wing forming at least two gate segments in Area of the guide device is arranged and parallel is movable and on the hinge connection attacks between the at least two gate segments in such a way that the two gate segments move relative to each other during opening and closing operations.

Accordingly, the drive device engages or the drive is not at the vertical edge of the gate adjacent gate segment or on the carriage which the outermost gate segment is suspended from, but on the hinge connection between the at least two Gate segments. From the drive device or from the drive become two opposite or opposite torques via the hinge connection to the two on the Hinge connection of interconnected door segments applied so that these two door segments and stretching movements relative to each other when opening and Carry out closing of the gate wing. In the course of the opening and the closing processes the drive moves along the guide device.

These measures result in comparison to the previous ones known folding gates have several advantages. That is among other things no large space requirement in the area of the vertical gate edge necessary for the drive devices to be provided there, because this compact drive device in the area the guide device in the horizontal gate edge is arranged. There is no need for rope or Chain drives for moving the door segments. An afterthought Installation in existing buildings is opposite previously known folding gates more easily possible because drive and guide device in the area of the upper horizontal Torrandes require little installation space and a floor side Guide rail with all of its disadvantages (Pollution, icing, etc.) is not necessary. There all for the opening and closing processes and the Guiding the door segments necessary components outside of the door segments, they can be designed in this way as desired, so for example with transparent or see-through door segment panels Etc.

Advantageous embodiments of the invention are Subject of the subclaims.

The guide device preferably has two in parallel mutually extending, convexly profiled in cross section Guide rails on which in the area of the upper horizontal Torrandes span the gate opening, taking the storage of the at least one gate segment over a plurality of concave profiled guide rollers, which together with the guide rails form a positive Form the backdrop. Through this configuration the guide device it is possible to handle even high loads by means of this guide device in the suspended state to guide safely and yet with low friction. This is especially true for large and heavy door segments essential.

Are still the guide rollers on a crossbar stored, which is the distance between the two guide rails spanned, at least on the crossbar a gate segment is rotatably suspended, respectively one gate segment is suspended from two guide rails at the same time, so that a better load distribution takes place. Farther is the parallel course of the two guide rails also outside the end storage ensured.

Is the hinge connection according to another preferred one Embodiment from an at least essentially extending over the entire height of the door segment Hinge shaft and one substantially the same length as this, the hinge shaft coaxially encompassing hinge sleeve built up, the hinge shaft with a Gate segment and the gate sleeve with the adjacent gate segment is connected, the hinge connection extends between two adjacent gate segments essentially over the entire height of the door segment, is therefore able to also heavy gate segments, which have a correspondingly high moment load exert on the hinge connection, sure to wear.

Will at least one hinge shaft and the associated one Hinge sleeve over the top edge of the respective door segment out into the area of the guide rails extended into, can be particularly advantageous Way of storage, that is, the suspension of each Gate segments on the guide device over the Create hinge shafts and hinge sleeves.

Preferred is in the area of the lower edges of the respective Gate segments at least one hinge shaft relative to the associated one Hinge sleeve by a certain length jumping back. In this way, according to a further preferred Design in the by the recessed Hinge shaft formed inside the hinge sleeve Clear a locking or locking pin vertically from Drive in below and thus the gate in its closed Lock position.

For reasons of stability, that is to say from the side To prevent rocking of the individual door segments is according to a further preferred embodiment of the drive in a box-shaped, in the direction of the guide rails arranged on both sides open drive frame, the by means of a form-fitting backdrop guide along the Guide rails are movably guided and stored.

Here are preferred according to a further embodiment the hinge shaft and the coaxial hinge sleeve designed to run into this drive frame and here in the area of the frame floor and frame ceiling stored. This is the drive between the two bearing points on the frame floor and the frame ceiling in a space-saving way and a favorable location from the balance of power arranged.

A drive motor is preferred in the drive frame an electric motor arranged, the output shaft with a Double gear train is coupled, the one gear train the torque of the drive motor on the hinge shaft transmits and the other gear train the same Torque of the drive motor with the opposite direction of rotation transfers to the hinge sleeve. This is it possible with a single drive motor the two opposite Movements for hinge sleeve and hinge shaft to generate, which then in turn when transferred to the each associated gate segments facing each other or inward or outward movement of the Door segments in the course of opening or closing the Gate wing causes.

If the double gear train has a high reduction ratio, which is, for example, a pairing a worm shaft on the output shaft of the motor can achieve a worm wheel, the gear train is in essentially self-locking so that if the drive motor fails the gate wing not easily by hand can be postponed.

According to a further preferred embodiment the gate segment adjacent to the vertical gate edge at this Torrand struck via an adjustment device, with which is the axis of rotation of this gate segment in one vertical plane in the closing and opening direction of the gate leaf can move, this vertical plane with the Longitudinal median plane of the gate wing in its closed Position and thus the longitudinal median plane of the guide device essentially escapes. Because of the special Conditions with folding gates of the type in question during the opening process at the beginning of the buckling movements of the individual gate segments a relative elongation of the whole Gate wing. Because such an elongation of the gate wing immediately after the opening of the gate begins that the free outer edge of the last door segment on the opposite vertical goal wall or with a double-leaf design of the entire gate abuts the outermost gate segment of the other wing or runs up, the adjustment device is provided, which when initiating the gate opening process Axis of rotation of the gate segment attached to the edge of the gate in Direction of this gate edge pulls, so that the relative elongation of the entire wing is compensated. Regarding Further details of this problem can be found at the beginning referred to generic DE-PS 28 40 074, which also deals with the problem of relative Elongation of a gate wing at the beginning of the buckling movement of the deals with individual gate segments.

The adjusting device is preferred by one each Washer at the upper and lower attachment point of the door segment formed, the gate segment in these discs eccentric is mounted such that when the Disks the adjustment movement of the axis of rotation of this gate segment in the vertical plane and in the closing or opening direction of the gate wing. By this arrangement or design can be done with simple construction Build up sufficiently high forces while being softer and Realize precisely controllable adjustment movement.

Here are the disks on a common, motorized arranged driven shaft is an absolute Synchronism in the adjustment movement without any Tilting movements ensured.

Also preferred is a cable pull device for support the opening movement of the gate wing is provided. This cable pulling device can be, for example, a cable drum have, which with the output shaft of the drive motor is coupled and when the drive motor rotates in Opening direction of the gate wing receives a rope that in Area of the vertical gate edge is posted. Also this represents a structurally simple embodiment represents, however, the desired effect, namely a support the opening process of the gate wing and a Relief of the hinge device on which the motor is over attacks the double gear train on completely satisfactory Way is achieved.

Due to the drive characteristics or the running properties the preferred gate to use is between a gear is arranged on the output shaft and the cable drum, so that the necessary high tensile forces in let the rope achieve.

The cable pulling device preferably has an idling range such that the rope only after a certain Swing path of the door segments to each other around the hinge devices is picked up by the rope drum. With others Words, in the fully closed state of the gate wing the rope must have a certain "sag", so that it is ensured that there is still no tension in the rope is built as long as the individual gate segments are still in the extended position. Only after the angling of the individual door segments to each other tensile stress builds up in the rope via the rope shaft, which supports the opening process and here in particular the hinge shafts and hinge axes, which coupled with the drive, relieved of the high forces.

The number of gate segments is preferably an integer multiple of two, with the drive on that Hinge connection attacks, which is in transverse extension of the gate wing seen this as a vertical axis of symmetry divided. In the case of, for example, two door segments, this therefore applies the drive on the hinge connection between the two gate segments and with four gate segments the Drive on the hinge connection between the second and third gate segment. An even application of force This ensures that it is applied and applied.

With six gate segments, however, are usually two drives necessary, one drive between the second and third and the other drive between the fourth and fifth gate segment attacks. Possibly can do without the use of two drives if, through appropriate auxiliary materials (springs, etc.) a defined folding and stretching movement of all six door segments is ensured.

This is preferred as seen from the vertical gate edge outermost gate segment hung on the guide device. This further relieves the hinge connections.

The door segment is preferably suspended here in the extension of its free vertical edge.

To buckle or bend the individual door segments must be ensured in the course of the opening process the axes of rotation of the hinge devices along one The longitudinal center plane of the guide device alternately laterally transferred.

Are two gate wings symmetrical in the area of each struck two vertical edges of the gate, so also cover very wide door openings.

According to a further preferred embodiment, can each door segment from a frame profile with one held in it Single or multiple glazing. Because of the special design of the hinge connection and in particular the control and the drive no additional components, drives or the like in the area within the frame of each gate segment necessary so that the entire area of the door segment (with Except the frame) can be glazed transparently. It it goes without saying that glass is not the only material for Formation of the gate segments is. For example, a fabric-covered, screen-like frames are used, if the folding door is only used as a privacy screen should. If necessary, can also be completely on a frame to be dispensed with; the fillings or sheets of each Gate segments then exist e.g. B. from glued glass plates, Wood, plastic or metal panels, Kevlar etc.

One according to the invention, designated overall by 2 in the drawing Folding door is shown schematically in Fig. 1 simplified front view shown in the closed state. The folding gate 2 is used to lock or release a gate opening 4, which is between a left wall section 6 and a right wall section 8 vertically and a floor 10 and a ceiling 12 is limited horizontally.

The folding door 2 is in the embodiment shown in Fig. 1 essentially from two to an axis A symmetrical gate leaves 14 and 16. Because of the structure of the two gate leaves 14 and 16 is identical only the right wing 16 of FIG. 1 is considered in more detail below.

The gate leaf 16 is in the illustrated embodiment made up of a total of four gate segments 18a to 18d. In general it can be said that the number of gate segments 18 should always be an integer multiple of two should. The rightmost in Fig. 1, the vertical gate edge formed by the right wall section 20 adjacent gate segment 18a is 20 at this gate edge via an adjusting device to be explained in more detail later 22 posted. The connection between the free End of the gate segment 18a and the next gate segment 18b takes place via a hinge connection 24a. Similar ones The gate segment 18c is over with the gate segment 18b a hinge device 24b and is the gate segment 18d with the gate segment 18c via a hinge connection 24c connected. The free, left in Fig. 1 and the left Gate 14 adjacent end of the gate segment 18d also has a hinge connection 24d, however no further gate segment at this hinge connection 24d more is struck, but a subsequent one Guide carriage 26 to be described in more detail, which in a guide device also to be described below 28 runs.

The attachment or the stop of the gate segment 18a on the vertical gate edge 20 also takes place via a Hinge connection 30, this hinge connection 30 is articulated on the adjusting device 22.

As can be seen from the top view of FIG. 2, the Hinge connections 20a to 24d and 30 along one Longitudinal median plane L seen alternately to both Sides of these longitudinal center planes L are arranged offset. This therefore, as a result of this during the opening process of the folding door 2 from the closed position shown in FIG. 2 in the open 3 then the door segments 18a and 18d have defined swiveling paths and thus in defined Swing out directions. When the folding door opens 2 2 pivots from the closed position Gate segment 18a around hinge connection 30 in a clockwise direction taking the hinge connection 24a on the dashed illustrated quarter circular path B. The gate segment 18b pivots against the hinge connection 24a Clockwise and around the hinge connection not visible in FIG. 2 24b also counterclockwise. The other gate segments 18c and 18d also pivot accordingly around the hinge connections 24b and 24c so that the left hinge connection 24d in Fig. 2, which on the Guide carriage 26 is articulated in Fig. 2 to the right is pulled along the left median plane L and thus the Gate wing 16, the right half of the gate opening 4 in FIG. 1 releases, with the individual gate segments 18a to 18d in the area of the gate edge 20, as in FIG. 3 shown.

The construction of the guide device 28 works best from Figures 2 and 5. The guide device 28 is essentially two in the area of the upper horizontal Torrandes or the ceiling 12 trending to each other constructed essentially parallel guide rails 32 and 34, on a corresponding substructure 36 are attached. The guide rails 32 and 34 have the 5 convex cross section ("<>") and are used for guiding and storing concave cross sections ("> <") profiled guide rollers 38a to 38d. Because of the convex shape of the guide rails 32 and 34 and the corresponding concave shape of the guide rollers 38a to 38d are the latter in the longitudinal direction of the guide rails 32 and 34 movable along these and in Directions perpendicular to this relative to the guide rails 32 and 34 fixed. The guide rollers 38a to 38d, which 2 each in pairs or in tandem 2 are present for both the guide carriage 26, which carries the last hinge connection 24d, as well as for a housing of a drive 40 (FIGS. 4 and 5) available. The guide carriage 26 consists essentially from a right angle to the guide rails 32 and 34 extending traverse 42, each end two pairs of guide rollers 38a and 38b or 38c and 38d carries and at the center the hinge connection 24d is pivotally articulated. In the course of the opening movement of the folding door 2, the cross member 42 in FIG. 2 runs from left to right, with the last gate segment at the same time 18d rotates about the hinge connections 24c and 24d, wherein the hinge connection 24c continues on a Quarter circle analogous to path B and the Hinge connection 24d rectilinear along the longitudinal central axis L moves.

The housing of the drive 40 is shown in FIG. 2 and in particular Fig. 5 from a functionally related to the traverse 42 analog traverse 44, on which a box-shaped, in Direction of the guide rails 32 and 34 on both sides open drive frame 46 is constructed. The drive frame 46 thus essentially consists of one through the crossmember 44 formed frame floor, two of the frame floor from vertically protruding side walls 48 and 50 and a frame ceiling 52 which is essentially to the frame floor or the traverse 44 runs parallel. With opening and closing movements of the folding gate 2 or the gate leaf 16, the cross member 44 and thus the drive frame 46 together with the guide carriage 26 along the guide rail 32 and 34 move, the guide rails 32 and 34 pass through the drive frame 46.

Figures 6 to 8 show the structure of one of the hinge connections 24, with FIGS. 6 and 8 in particular the structure of the middle hinge connection 24b in FIG. 1 show which - similar to the hinge connection 24d - beyond the upper level of gate leaf 16 into the area the guide device 28 is extended into it. There these relevant hinge connections in the area of Guide device 28 and thus in the drive frame 46 are extended, there is a very high rigidity of the individual gate segments and thus the gate wing 16 to lateral forces (whereby this stiffness is all the greater is, the higher the drive frame 46 builds), so that in advantageously on lower bottom guide rails with all its disadvantages (pollution, icing etc.) can be dispensed with.

Below an altitude H (Fig. 8) is the construction of all Hinge connections 24a to 24d essentially equal. The following made for the hinge connection 24b In this respect, statements also apply to the remaining ones Hinge connections 24a, 24c and 24d too.

The hinge connection 24b is essentially in two parts constructed from a hinge shaft 54 and one of these coaxial and rotatable surrounding hinge sleeve 56. Die constructed from the hinge shaft 54 and the hinge sleeve 56 Hinge connection 24b runs essentially over the entire vertical elevation of each other adjacent gate segments 18b and 18c. Here is the gate segment 18b with the hinge sleeve 56 in connection and that Gate segment 18c is connected to the hinge shaft 54. (It should be noted here that the extension of the gate segments 18b and 18c in Fig. 8 schematically on two next to the hinge connection 24b reduced stripe is simplified). The articulation of the door segment 18b on the hinge connection 24b or its hinge sleeve 56 takes place via a Plurality of hinge portions 58a and 58b (in FIG. 8 only two such hinge sections are shown; it is understood that in practice a plurality of such Hinge sections along the length of the Hinge connection 24b is provided). The hinge sections 58 are in rotation with the hinge sleeve 56 Connection. In the between the hinge sections 58a and 58b available spaces are further hinge sections 60a and 60b used (of which in turn in Fig. 8 only two are shown; in practice is one A plurality of these hinge sections 60a and 60b along the Length extension of the hinge device 24b available). These hinge sections 60a and 60b are non-rotatable with the Hinge shaft 54 connected. The hinge connection 24b 8 is thus structurally with a hinge connection comparable, which is known as the "piano band" is. Due to the design of the hinge connection 24b takes place with a rotation of the hinge shaft 54 relatively a corresponding relative rotation to the hinge sleeve 56 of the gate segment 18c to the gate segment 18b. Same thing hits for the hinge connection 24a and the gate segments 18a and 18b and the hinge connection 24c and the Gate segments 18c and 18d too.

According to FIGS. 6 and 8, 54 is on the hinge shaft A carrier plate 64 is arranged in a rotationally fixed manner via a sleeve 62. In the same way is via a sleeve 66 on the hinge sleeve 56 a carrier plate 68 arranged in a rotationally fixed manner. The Carrier plates 64 and 68 thus rotate together with the Hinge shaft 54 and the hinge sleeve 56 and guide one Angular movement relative to each other. The carrier plates 64 and 68 are used to initiate movement torques for the hinge shaft 54 or hinge sleeve 56, as follows will be explained later.

5, the hinge shaft 54 of the hinge connection 24b through an opening 70 in the ceiling 12 between the two guide rails 32 and 34 in the Drive frame 46 guided into it. The hinge shaft 54 extends down to the area of the frame ceiling 52 of the drive frame 46 and is rotatable there by means of a bearing 72 stored. In the area of the frame floor or the traverse 44 passes through the hinge shaft 54 with the cross member 44 non-rotatably connected gear, as will be explained. Above this gear are the laterally projecting ones Carrier plates 64 and 68 arranged. On these carrier plates 64 and 68 is a transmission half 78a and 78b of a double gear train built. The more precise Structure and the more precise mode of operation of the transmissions 78a and 78b is explained below.

In the area of the side wall 48 of the frame is a drive motor 80 arranged, in particular a corresponding dimensioned electric motor is. The motor 80 carries a worm shaft 82 on its output shaft Worm shaft 82 is in engagement with a worm wheel 84, which on a separately running sleeve 86 'with bearings 88 is stored. Two identical teeth sit on the sleeve 86 Gears 100a and 100b rotatably. To these two gears 100a and 100b, the gears 78a and 78b are attached, whereby a transmission half, namely the transmission half 78b for Reversing the direction of rotation has a gear 102 more. At in the same direction drive via the motor 80 is carried out by the Gear 102 reverses the direction of rotation to the folding effect to achieve the two gate segments 18b and 18c to one another, as will be explained below.

In the lower area of the gear 78a and 78b are on there shafts 104a and 104b rotatably arranged gears 106a and 106b engaged with the non-rotatable or rigid on the crossbar 44 arranged gear 108 through which the rotating shaft 54 extends. The running movement of the gears 106a and 106b around gear 108 is approximate, respectively 40 ° in opposite directions. The gear halves 78a and 78b, which rigidly on the carrier plate 64 of the Hinge shaft 54 and on the support plate 68 of the hinge sleeve 56 are mounted, thus run in opposite directions Towards or away from each other and indicate the movement via the carrier plates 64 and 68 the hinge connection 24b or the hinge shaft there 54 and hinge sleeve 56 further, so that the gate segments 18b and 18c make movements relative to each other, in their Course the gate segments 18b and 18c either from the straight 2 in the folded position 3 or in the opposite direction of rotation of the motor 80 from the folded, the open Corresponding position back in 2 according to the closed position Position. In the course of the buckling movement the gate segments 18b and 18c also guide the gate segments 18a and 18d corresponding buckling movements relative to the neighboring ones Gate segments 18b and 18c through, at the same time the trusses 42 and 44 along the guide rails 32 and 34 will be followed.

The expert in the field of gear theory recognizes that that shown in the drawing and described above Design of the gear halves 78a and 78b not this illustrated embodiment must be limited. Essential is just that about the drive the two Main elements of the hinge connection 24b, that is the hinge shaft 54 and the hinge sleeve 56 an opposite Rotate towards each other to make the buckling or stretching movement to achieve the gate segments 18b and 18c.

To the hinge connection during the opening process of the gate leaf 16 24b from the high forces of the gear 78a and to relieve 78b is still a cable pulling device 110 available. This cable pull device 110 essentially comprises a rope drum 112 on which a rope 114 can be received or from which the rope 114 can be unwound. The Rope 114 is firmly attached in the area of the gate edge 20. With an opening movement of the gate leaf 16 from the position 2 out of the rope 114 by itself rotating cable drum 112 added so that the drive frame 46 is pulled in the direction of the gate edge 20. Here it is important that the rope drum 112 has a diameter the gearbox movements are coordinated: because the hinge axes the hinge connections 24a to 24d in the closed State of the gate leaf 16 according to FIG. 2 in a negative Angles, (caused by the bilateral staggered arrangement of the hinge connections 24a to 24d relative to the median longitudinal plane L), this negative angle with an opposite angle of the gate segments 18a to 18d or the axes of the hinge connections 24a to 24d be overcome. This process can only be done from the gearbox halves 78a and 78b. A pull effect via the cable 114 to the housing of the drive 40 do not cause this angulation process. Only after Angle the gate segments 18a to 18d in a positive The cable drum 112 may intervene to support the angle and the gate segments into the collapsed or collapsed Move position according to Fig. 3. The stretching length of the Gate leaf 16 results from the center distances of the hinge connections 24a to 24d and the distance of the hinge connection 30 to hinge connection 24a if all of these Axes are in line. Up to this angle no tension is applied to the cable 114 by the cable drum 112 become.

Equally, care must be taken to ensure that the individual door segments 18a to 18d from their fully collapsed, 3 "parking position" in the area out of the Torrandes 20 back into the stretched position 2 can be moved, in the initial phase the closing movement from the position of FIG. 3 the drive 40 needs support. This is an auxiliary drive not shown in the drawing in the area of the gate edge 20, which at the beginning of the Closing the first gate segment 18a against the Torrand 20 drives and creates a certain closing path, then the drive 40 the final Closing takes over without being overcharged to become. The auxiliary drive is preferably an energy store, For example, a spring that opens Force is saved and saved when the gate is open holds and then this force when initiating the closing process passes to the gate segment 18a and it in the closing direction drives.

Due to the arrangement of the worm shaft 82 and The worm wheel 84 has a very high reduction ratio. Therefore, with the drive motor stopped 80 the entire drive self-locking or blocking what already a first security measure against unauthorized persons Opening the folding door 2 or one of its gate leaves 14 and 16 represents.

To further secure the closed state is 8 a locking or blocking pin 116 is provided, with the at least one of the hinge connections 24a to 24c is prevented from swinging out. This Locking pin 116 can from the level of the bottom 10 of be moved down into a free space 118, which thereby is formed that at the lower end of a hinge connection, example of the hinge connection 24a, the Hinge shaft 54 springing back relative to the hinge sleeve 56 is made. With the locking pin retracted 116 the respective hinge connection or can - In the presence of a plurality of locking pins 116 - the respective hinge connections are not swing out more so that together with the self-locking the drive of the respective gate wing safely in its closed position is fixed.

As already mentioned, each gate wing 14 or 16 experiences due to the arrangement of the hinge connections 30 and 24a to 24d on both sides of the longitudinal central axis L directly after initiating the opening process, an elongation or Stretching, which would cause an opening operation the two gate leaves 14 and 16 in the region of the axis of symmetry A touch each other so that the gate wing 14 and 16 upset and / or the drives are damaged would. To prevent this, each gate wing 14 or 16 in the area of the lateral vertical gate edge 20 the adjustment device 22 is mounted. Fig. 9 shows schematically the construction of such an adjustment device 22. The adjusting device 22 consists essentially of two Eccentric disks 120 and 122, which rotate against one another Shaft 124 are interconnected. Here is the eccentric disc 120 in the area of the ceiling 12 and is the eccentric disc 122 arranged in the region of the bottom 10. The Shaft 124 is composed of a drive Worm gear 126 and a worm shaft 128 via one Motor (not shown) can be rotated. In the Eccentric discs 120 and 122 is the gate segment 18a the hinge connection 30 hinged. The hinge connection 30 is shown schematically in FIG. 9 by two pins 130a and 130b illustrates which is in a guide recess 132a and 132b are held, the guide recess 132a in the disk 120 and the guide recess 132b is formed in the disk 122. The shape of the Eccentric discs 120 and 122 and the course of the respective Guide recesses 132a and 132b is such that at one synchronous rotation of the eccentric discs 120 and 122 the motor-driven shaft 124, the pins 130a and 130b a movement directed to the left or right in FIG with the pins 130a and 130b each in Elongated holes 134a and 134b in the ceiling 12 and the Floor 10 slide.

Movement of pins 130a and 130b in FIG. 9 after on the left causes a relative shortening of the whole the gate segment 18a adjoining gate wing and a corresponding reverse movement with reverse direction of rotation of the eccentric discs 120 and 122 causes a movement in Fig. 9 from left to right corresponding to a relative Elongation of the respective gate segment. A stretching motion of the respective gate 14 or 16 immediately after the start the opening process can thus be done by a movement the pins 130a and 130b in Fig. 9 from right to left be compensated.

The rotation of the motor for the worm shaft 128 each in the area of a lateral vertical gate edge 20 is via a suitable control with the motors 80 in the respective drives, as well as with the entry and exit movements the locking pins 116 synchronized so that the entire movements of the folding door according to the invention 2 essentially divided into the following individual movements can be:

The first is from the closed state according to FIG Movement by unlocking the gate wing (s) pull back the locking pins 116 from the free spaces 118. The locking pins 116 are over, for example Electromagnets move.

This is followed by pulling apart as a second movement of the two gate wings 14 and 16 by the respective Adjustment devices 22 on.

Immediately afterwards, the pivoting takes place as the third movement of the gate segments 18a to 18d to each other through the Gear 78a and 78b in the area of the ceiling 12 with support by the cable pull device 110. This third movement process continues until the fully open position is reached according to Figure 3, where the individual gate segments 18a to 18d lie against each other.

To transfer the folding door 2 or its gate leaves 14 and 16 from the open state according to FIG. 3 to the closed one According to Figure 2, the above sequences of movements in reverse order.

At this point it should be noted that in the schematic representation of Figure 1, the size of each Drives 40 with respect to the vertical height extension the gate wing 14 and 16 shown exaggerated is. In practice, the drives 40 build with the gears 78a and 78b opposite the gate segments or gate wings much smaller or lower.

The present invention therefore completely creates one new type of folding door, in which the Drives for moving the gate leaf or gate leaf directly on the respective connecting the gate wings together Attack hinge connections and oppose each other directed torques the swivel movements initiate the relevant gate wing relative to each other. The remaining number of gate segments is through this motor-driven pivoting movement is also pivoted, so that the gate wing in question with a drive can be opened and closed. Because of the compact and space-saving design of the respective drive this needs in the area of the ceiling 12 above the gate opening 4 only a small installation space. Furthermore, there are none Drive elements in the area of the door segments 18a to 18d visible, since this is together with the guide device 28 outside the gate opening 4 above the ceiling 12 are located. Also in the area of the floor 10 are exceptions one or more openings for driving through the locking pins 116 no guide rails or the like necessary so that the entire folding door 2 is aesthetically pleasing makes an appealing impression, e.g. then when the individual Door segments 18a to 18d made of frame profiles with a single or multiple glazing. By the There is no need for a bottom guide rail also no problems with soiling or freezing.

The individual movements are known per se Way via a suitable control and limit switches or sensors suitably matched and regulated.
