Description

The invention relates to a vertically movable door with a door leaf, which has a plurality of door leaf segments, according to the preamble of claim 1.

Lift gates of this type are used for opening and closing passages or passages. They are often used as garage doors or as gates for delivery ramps. But they are also used as a room divider in warehouses. Since these goals often have a high weight, they are usually driven primarily by a motor.

Such a motor drive usually has at least one motor, which is connected via drive means, such as drive belts or drive chains, with the gate. Depending on the speed and torque of the engine so-called, common in the industry, high-speed doors can be realized. Gate speeds of up to 4 m / s are achieved with high-speed doors, whereas the door leaves are moved at typical industrial lifting doors with speeds of typically 0.2-0.3 m / s.

Gates of the type mentioned are, for example, from the DE 10 2012 101 415 A1 known. This document discloses a door with a motor drive, the drive means on the load side, a drive chain and the empty side has a drive belt. Between belt and chain a driver piece is arranged, which serves for connection to the multi-segment door leaf. While the individual Torblattsegmente are connected to each other with hinges, the lowermost Torblattsegment is connected via the driver piece with the drive chain.

The DE 10 2009 044 492 A1 also discloses a vertically movable door having a multi-segment door leaf. The gate is moved via a motor drive, wherein a toothed belt serves as a force-transmitting drive element. The individual Torblattsegmente are interconnected with hinges, wherein the toothed belt engages a bottom end portion of the door leaf, ie the lower end element or the lower door leaf segment.

The lifting gates known from the prior art favor in a simple manner a connection of the door leaf to the drive means. The individual Torblattsegmente are interconnected with hinges. The lowest door leaf segment is connected to the drive means. So a simple connection to the motor drive is realized. The loads acting on the door leaf in a motor drive also largely correspond to the loads that occur when the door is raised manually.

Age-related changes in length of the drive means also have no significant effect on the synchronization of the door leaf or the individual door leaf segments with each other. In addition to the static weighting forces of the door leaf, the connecting means must also absorb the dynamic forces which occur during operation, which can be very great, especially in high-speed doors. The connecting means connecting the lowermost Torblattsegment with the drive means must therefore be dimensioned according to the size and weight of the door leaf.

Larger drives or larger connecting means, however, at the same time require a larger space, which usually causes a widening of the door frames and thus in turn a limitation of the passage height or passage width of the door.

The invention is therefore based on the object to improve a goal of the type mentioned in that this goal is largely independent of the forces occurring between an open and a closed position movable, while still a compact and stable and reliable construction having.

This object is achieved by a gate with the features of the characterizing part of claim 1.

The connection of several individual Torblattsegmente with the drive means leads to the positive effect that both the static and the dynamic forces are introduced at several points in the door leaf or in the drive means. Thus, there is a distribution of the forces occurring at several connection points between the drive means, connecting means and door leaf segment.

The drive means experiences when opening the gate for the most part tensile load. Pressure load between the door leaf segments of known from the prior art Torblattsegmenten can be significantly reduced or even avoided.

Even large or heavy gates thus remain well movable between an open and a closed position despite the associated rising forces occurring. The inventive compound of several individual Torblattsegmente with the drive means also has the advantage that due to the division of the total force to a plurality of connection points, the connecting means for connecting the drive means with the door leaf may have correspondingly smaller dimensions, which in turn leads to a compact overall construction of the entire gate. In addition, also the drive means in Its dimensions are reduced, which is conducive to a compact construction of the gate further.

In one possible embodiment of the invention, each Torblattsegment be connected to the drive means. Thus, the forces are distributed to all joints between the drive means and door leaf and thus on the entire door leaf or on the entire drive means.

The drive means may for example be a finite drive means, preferably a chain, and in particular a hollow pin chain.

In a finite drive means can be dispensed with its return on the side of the return strand and on a pulley at the bottom of the door, whereby a saving of installation space can be achieved. Serving as a drive means chain represents due to their limited change in length during long-term operation is a particularly advantageous embodiment of a drive means for such gates. In particular, a hollow pin chain for a reduction in weight of the drive means at the same time high load capacity.

It is conceivable that the connecting means extends through a part of the drive means. Thus, a good and direct as possible power transmission between the drive means and the door leaf. In addition, as a compact design of a provided between the drive means and door leaf connection point can be realized.

Possibly, a connection means may be arranged in the hinge region of a hinge, and in particular may be a hinge pin connecting the two hinge parts of a hinge. Such a design of the connecting means provides for a particularly advantageous and space-saving arrangement. In particular, when the connecting means is designed as a hinge pin, can be dispensed with an additional separate hinge pin, which in turn contributes to a compact design of the door.

Furthermore, it is proposed that a trade of a hinge has at its one end a fixed bearing and at its opposite end a floating bearing. In this way, a bearing with rotatory and a bearing point with rotational and translational degree of freedom is realized, so that in a particularly advantageous manner, a non-destructive change in length between two hinge picking is possible.

It is also conceivable that the individual hinged hulls are connectable to each other and form a hinge chain. With such a hinge chain, the individual Torblattsegmente be easily assembled into a common stable door leaf, the individual Torblattsegmente can be performed in lightweight construction.

Possibly, the hinges of a hinge may be combined with the drive means. A combination of drive means and hinge fittings can combine the individual functions of these two parts and saves space compared to a separate training of both parts. This again serves a compact construction of the door.

The drive means may be integrated with the hinge fittings of a hinge. It is conceivable that the drive means is arranged for example in a recess, in a cavity or in the interior of the hinge. An integrated arrangement of the drive means in the hinge fittings ensures a narrow and compact design of the drive and thus to a compact construction of the door.

It is also conceivable that the industries of a hinge have a recess for receiving the drive means, wherein the recesses of the individual businesses are arranged in alignment with each other. Thus, the recesses provided in the individual trades can provide a kind of channel for the drive element, this channel of receiving and guiding and the protection of the drive means from external influences, such as an external mechanical force can serve.

According to one embodiment of the invention may be provided between the drive means and at least one surface of a hinge industry, a damper, which may be suitable to dampen a relative movement between the drive means and the hinge treasure. Such a damper can restrict the mobility of the drive means relative to the hinge and thus reduce on the one hand noise and on the other hand the wear of a collision of the drive means on the hinge Dye when opening and closing the door leaf.

The drive means may be inserted into the recess of the hinge, wherein the connecting means connects the drive means with the hinge items. If the drive means is inserted into the recess, a particularly space-saving arrangement can be realized, in addition, the connecting means, which connects the door leaf with the drive means, can be used simultaneously for connecting the hinge items.

It is conceivable that the connecting means comprises a collar having a guide roller for horizontally guiding the Torblattsegmente in a vertical movement of the door leaf, and in particular that the connecting means is a guide roller bearing this axis. In situations where external forces, such as a wind force, act on the door leaf, this can result in individual door leaf segments being forced out of the door frame in an approximately horizontal direction. A covenant leadership can counteract this. Such a role can also lead the door leaf in a vertical movement in the frame. In order to save space despite the use of such a leadership role, the connecting means may be designed as a roller bearing this leadership role.

In particular, a sliding element can be arranged between at least one surface of a door frame profile and at least one hinge piece, which can in particular be held on the connecting means. The sliding element causes a horizontal guidance of the door leaf during its opening and closing movement. Possible wear caused by friction can occur to a large extent on the sliding disks and to a lesser extent on other components of the device.

In one embodiment, the sliding element may be provided between the hinge body and a guide roller. As a result, the horizontal position of the sliding element can be determined and the guide roller can be supported against the hinge lining. It is also conceivable that the drive means and the hinges are arranged between a guide roller and a door leaf segment. This leads to a particularly space-saving arrangement of the individual parts with each other, which in turn contributes to a compact design of the door.

Furthermore, it would be possible for a hinge to have at least one side guide element which is suitable for guiding the door leaf segment connected to this hinge system in the horizontal direction during a vertical movement of the door leaf. Thus, a correct guidance of the entire door leaf during a vertical movement can be ensured, which contributes to a good operability of the door.

In one possible embodiment of the invention, the respective hinge harvesting unit can be arranged on a front end side of the respective door leaf segment facing the door frame. In addition, the respective hinge can extend approximately over the entire height of the respective Torblattsegments. Thus, a particularly simple embodiment of the individual hinge accretions, for example as a simple injection-molded part, can be realized. A Extension of the hinge industry over approximately the entire height of the door leaf segment offers the advantage that a large connecting surface is provided between the door leaf segment and the hinged lining, so that a good connection can be realized.

Optionally, the respective hinge can be arranged in a cavity of the respective door leaf segment and be connected substantially within this cavity with the respective Torblattsegment, wherein the respective hinge Dye and the respective Torblattsegment are preferably connected to each other via an adhesive bond. This arrangement of the hinge industry in a cavity of the door leaf segment offers the advantage that the hinge treasure is arranged at least partially within the door leaf segment, which is useful for a compact construction of the door. In addition, a sufficiently large surface is available for adhesive bonding of both parts.

Conveniently, at least one hinge system can be connected to a door leaf segment by means of a screw connection, wherein preferably the door leaf segment can have at least one bore with a thread and the hinge can have at least one through-hole through which a screw can extend. The screw is a cheap and reliable connection, which also allows to disassemble Torblattsegmente of the hinges and replace depending on the task field, whereby the door leaf with less effort is adaptable to different tasks.

It is proposed that the connecting means in the upper half of a Torblattsegments, and in particular in the region of an upper edge of the door leaf segment, is connected to the respective Torblattsegment. Since the connecting means in the upper half, i. is above the tilt axis of the door leaf segment, a suspended support structure is realized, wherein a Torblattsegment of gravity depends on the connecting means down. Thus, the individual Torblattsegmente be drawn in a vertical movement of the door leaf of the drive means, which leads to a tightening of the individual Torblattsegmente with each other and thus improves the stability and the operability and durability of the door.

In an advantageous variant, a drive element, preferably a sprocket, can engage the drive means and be provided above a passage height of the door, preferably in a lintel. By arranging a drive element above the headroom and in particular in the lintel, the frame width can be kept low. The passage height is also kept as large as possible, since the drive element is received in the frame above the passage height.

Possibly, a guide may be provided, which holds the elongated drive means in the region of the drive element in engagement with the elongate drive means. It is thus supported a more even and safer drive the door leaf.

In a further development of the invention, the guide may comprise at least one counter-holding means, which keeps the elongate drive means urged in the direction of the drive element and in particular may be suitable for engaging in a hinge picking. Thereby, the engagement between the drive means and the drive element can be further improved. When the hinge is coupled to the drive means, the counter-holding means can act favorably on the drive means upon an attack on the hinge.

According to one embodiment, the guide may comprise at least one retaining roller, which is particularly suitable for rolling on a hinge to attack. By means of the retaining roller, any friction occurring between the guide and the movable components of the door can be reduced, resulting in less energy required for movement of the door leaf and less wear.

Identical reference characters are used for repetitive features in different figures.

FIG. 1 shows a gate according to the invention with a door leaf 1, which has a plurality of door leaf segments 2. The gate is vertically movable, the door being opened in the direction of the arrow A and closed in the direction of the arrow B.

In each case two adjacent Torblattsegmente 2 are hingedly connected to each other via at least one hinge 3. As in FIG. 2 1, a hinge 3 has two hinge items, namely a first hinge piece 31 and a second hinge piece 32 hingedly connected thereto. The hinge trucks 31, 32 may be made of metallic materials or of plastics such as fiber reinforced polyamide.

The gate according to the invention is moved by means of a motor drive, not shown, between an open and a closed position. The force required to lift and lower the door leaf 1 is transmitted to the door leaf 1 via at least one drive means, in the present exemplary embodiment via a chain 4, from the motor drive.

Connecting means 5 connect the chain 4 with the door leaf 1. Here are several Torblattsegmente 2 each individually connected to the chain 4. The connection means 5 will be described below with reference to FIG FIG. 4 explained in more detail. Only a few of the door leaf segments 2, but also all the door leaf segments 2, can be connected to the drive means 4.

In FIG. 2 the serving as drive means chain 4 can be seen. In this embodiment of the invention is a hollow pin chain, that is, the individual members of the chain 4 are connected to each other with hollow bolts 7. By such a hollow bolt 7, for example, a connecting means 5 can extend through.

As in FIG. 3 can be seen, each serving as a drive means chain 4 can be located at the outer ends of the door leaf 1. The gate can therefore be actuated either with one or with two drive means. The chain 4 is formed as a finite driving means. The lower end of the chain 4 is located on the lowermost Torblattsegment, the upper end of the chain 4 is located on the uppermost Torblattsegment.

FIG. 4 shows a cross-sectional view along in FIG FIG. 3 pictured section line IV-IV. Shown is a hinged haulage 32, which is connected to a Torblattsegment 2. The hinged haulage 32 has a recess 6 in which the chain 4 finds room. The chain 4 is inserted into the recess 6 of the hinge industry 32.

In FIG. 4 a single chain link 41 is shown with a hollow pin 7. A connecting means, here a hinge pin 5, extends in its axial direction through the hinge treasure 32 and through the hollow pin 7 of the chain link 41 therethrough. The hinge pin 5 is secured to a Torblattsegment 2 facing the end 8 with a pin 9 against axial translational and radial rotational movements. At the opposite end of the hinge pin 5 is fixed by suitable means, here with a nut 11.

A guide roller 12 is rotatably supported by commercially available bearings 13 on the hinge pin 5. The guide roller 12 is disposed in the axial direction between the nut 11 and the hinged harvesting 32. The guide roller 12 has a tread 14 and an outer collar 15. The outer collar 15 is spaced further from the central axis L of the hinge pin 5 in the radial direction than the running surface 14. The collar 15 serves to guide the door leaf segments 2 horizontally during a vertical movement of the door leaf 1.

FIG. 10 shows the arrangement according to the invention, which is at least partially in a Torzargenprofil 16. The Torzargenprofil 16 is shown in a cross section. It is a segmented hollow profile, in the interior of which at least two profile parts 17 are approximately symmetrical. The clear width W of the two profile parts 17 is slightly larger than the diameter D _L at the running surfaces 14 of the guide roller 12. The guide roller 12 is disposed between the two profile parts 17.

The profile parts 17 have opposite running surfaces 18 which can come to rest with the running surfaces 14 of the guide roller 12. Due to this arrangement of the guide roller 12 between the two oppositely arranged profile parts 17, the guide roller 12 is guided, including the attached door leaf segment 2 in a vertical movement of the door panel 1 in its vertical direction of movement.

The collar 15 of the guide roller 12 has a diameter D _B , which is greater than the diameter D _L at the running surfaces 14 of the guide roller 12. The diameter D _{B of} the collar 15 is also greater than the inside width W of the two profile parts 17. From this results in a contact surface 20 on the inside of the collar 15, which can reach 17 with an oppositely arranged contact surface 19 of the profile parts 17 to the plant.

If, for example, a force F acts on a door leaf segment 2, this leads to a deflection of the door leaf segment 2 and thus to a translatory movement of the door leaf segment 2 in the direction of the movement arrow V. In such a case, the collar 15 of the guide roller 12 prevents the guide roller from sliding out 12 and the door leaf segment 2 arranged thereon from the profile parts 17 of the door frame profile 16. The door leaf segment 2 is thus guided approximately horizontally in a vertical movement of the door.

At one of the opening of Torzargenprofils 16 opposite side is a photocell 45, by means of which it can be monitored whether the door is in the open or closed state or whether an obstacle obstructs the path of the open door leaf 2.

On the opposite side of the drive means 4 of the hinge 31 is a holding roller 44 which is rotatably mounted on Torzargenprofil 16 and the task assumes a leadership. When opening and closing the door leaf 2, the retaining roller 44 rolls over the surface of the hinge 31 from which the drive means 4 is opposite and with which the retaining roller 44 is in contact.

The retaining roller 44 is located in the upper region of the closed door leaf in the area of the lintel to improve the engagement of the sprocket in the drive means. It is also possible to provide a plurality of retaining rollers 44 on the Torzargenprofil 16, for example, distributed in the lower part of the closed gate or over the height of the door.

In the recess 6, in which the chain links 41 of the drive means 4 is received, a damper 43 is provided between the drive means 4 and a rear surface in the recess 6, with which both the recess 6 and the drive means 4 are in contact.

The damper 43 may be made of a soft and / or elastic material, for example of an elastomer.

In FIG. 6 a hinge 3 is shown. The hinge 3 has a first hinge acquisition 31 and a second hinge acquisition 32. Both hinge trucks 31, 32 each have an aligned bore 21 through which the connecting means 5 extends. The connecting means 5 serves as a hinge pin 5 and forms a hinge axis about which the hinge 3 is pivotable in a known manner.

In FIG. 7 a single hinged haulage 31 is shown by way of example. The hinged haulage 31 has a guide section 22 on an outer lateral end side. The guide portion 22 consists of two vertical walls 22a, 22b and an intermediate horizontal wall 22c connecting the two vertical walls 22a, 22b. The resulting U-shape forms a recess. 6

The inside width Z of the recess 6 is slightly larger than the width B _{K of} the chain 4 (see FIG. 3 ). The chain 4 finds place in the recess 6 and can be inserted into the recess 6.

At the door panel segment 2 facing vertical wall 22b, the hinge treasure 31 has a connecting portion 23, which is preferably formed integrally with the guide portion 22. The connecting portion 23 has an outer shape which corresponds approximately to the inner hollow profile 24 of the door leaf segment 2. A Torblattsegment 2 can be postponed so fitting on the connecting portion 23.

The hinge piece 31 is arranged in a cavity 25 of the door leaf segment 2. In order to provide a secure connection between the hinged haulage 31 and the door leaf segment 2, the hinge haulage 31 is preferably glued in the region of the connecting portion 23 with the door leaf segment 2. Other forms of connection, such as screw, but this is not excluded.

As in FIG. 9 can be seen, hinge on 31, 32 on both sides of a Torblattsegment 2, with reference to FIG. 7 described manner, be appropriate. Further shows FIG. 9 in that the respective hinge harvesting unit 31, 32 is arranged on a front end side 26 of the door leaf segment 2 pointing towards the door frame 16 and extends approximately over the entire height h of the door leaf segment 2.

The individual hinge units 31, 32 of a hinge 3 have the same external shape and are in particular approximately identical parts, preferably injection-molded parts. In the FIGS. 7 and 8 It can be seen that a hinge 31, 32 at one axial end 27 has a bore 21 for receiving a hinge pin 5. In FIG. 4 Such an arrangement can be seen in cross-section, wherein a hinge pin 5 is guided by just these holes 21 of the hinge industry 31.

The inner diameter of the bore 21 is slightly larger than the outer diameter of the hinge pin 5. The arrangement of the hinge pin 5 in the bore 21 realizes a fixed bearing with a rotational degree of freedom, i. the hinged haulage 31, 32 can rotate about the hinge pin 5 with the bore 21 attached to one axial end thereof.

To secure the hinge pin 5 against rotation or displacement, a previously described pin 9 is inserted through an opening provided in the hinge pin 5 hole which extends transversely to the longitudinal axis L of the hinge pin 5. The cotter pin 9 is also inserted through a transverse bore 29 introduced at the hinge conveyor 31 ( FIG. 7 ), which is preferably provided in the connecting portion 23.

In the FIGS. 6 . 7 and 8 It is shown that a hinge 31, 32 on its other axial side 28 has a slot 30. The elongated hole 30 is a bore which extends approximately in the longitudinal direction Y ( FIG. 8 ) is extended. The inner diameter d of the elongated hole 30 is slightly larger than the outer diameter of the hinge pin 5. Thus, a floating bearing is realized, the hinge treasure 31, 32 due to the slot 30 both rotationally and translationally in the Y direction, ie along the extension direction of the elongated hole 30th , around the hinge pin 5 is movable around.

How best in the Figures 2 . 3 and 6 can be seen, the individual hinged purchases 31, 32 are connected to each other, so that they form a hinge chain 300. The ends 27, 28 of a hinge 31, 32 are shaped so that they are each overlapping with the holes 21, 30 fitted into each other. Thus, on the insides of the holes 21 ( FIG. 7 ) of a hinge trade 31, 32 recesses 34 are provided, in which the fork ends 33 of an adjacent hinge trade 31, 32 can be fitted. Since the hinge units 31, 32 all have the same shape, the individual hinge units 31, 32 can be assembled to form an arbitrarily long hinge chain 300.

Each hinge mechanism 31, 32 has a side guide element 35, which is suitable for closing the door leaf segment 2 connected to this hinge mechanism 31, 32 against the horizontal direction V (FIG. FIG. 10 ) support against a vertical movement of the door leaf 1 against the profile part 17 and lead. The side guide member 35 is on the lateral outside the first vertical wall 22a of the guide portion 22 of a hinge trade 31, 32 arranged.

FIG. 11 shows an alternative embodiment of the door leaf 1, which includes a sliding washer 42. The nature and perspective of the representation corresponds to those already in FIG. 10 selected, but for a horizontally opposite side of the door leaf.

In this embodiment, the door leaf 2 has no side guide member 35 and no damper 43. For lateral guidance of the door leaf 2, a sliding element 42 is provided between the hinge conveyor 31 and the guide roller 12, which thus relative to the guide roller 12 the collar 15 in the axial direction opposite. In a horizontal displacement of the door leaf 2, the slider 42 can come into contact with the Torzargenprofil 16 and slide along it to limit the horizontal mobility of the door leaf 2. In the embodiment shown, the sliding element 42 is approximately round and provided with a central hole, wherein the connecting means 5 extends through this hole and thus fixes the sliding element 42.

The sliding element 42 may be made of a low-friction and / or comparatively soft material in order to minimize frictional forces between the sliding disk 42 and the Torzargenprofil 16 and the wear of the guide roller and the Torzargenprofils 16. In particular, when in each case a sliding element 42 is provided at the two horizontally opposite connecting means 5 of a Torblattsegmentes 2, the horizontal guidance of the guide rollers 12 can be made substantially by the sliding member 42.

The door leaf 2 may have distributed over its height a plurality of sliding elements 42. For example, the sliding elements 42 may always be arranged in pairs horizontally opposite each other. Such pairs of sliding elements 42 may be evenly distributed over the height of the closed door leaf, for example, with a total of three pairs at the top, at the bottom and in the middle approximately.

FIG. 12 shows an alternative embodiment of the connection between a door leaf segment 2 and a hinge 31 in an exploded view. In this embodiment, the door leaf segment consists of two profile elements 49 and a shutter 50 received between the profile elements 49. The profile elements 49 may be made of metal, for example, preferably of aluminum. For the diaphragm numerous materials are also possible, for example metals or plastics, preferably transparent plastics.

The profile elements 49 each have a screw hole 47 with an internal thread. The hinged haulage has in this embodiment, two through holes 48, whose distance from one another correspond to the spacing of the screw holes 47 of the door leaf segment 2. The connection between hinged haulage 31 and door leaf segment 2 can be made by screws 46 are screwed through the through holes 48 of the hinge 31 and the screw holes 47 of the profile elements 49.

Fig. 13 shows the location of the lintel 51 and dependent therefrom passage height 52 of the gate. In the lintel 51, the door leaf 2 can be rolled up in the form of a screw 54 when it is open. The drive element is designed in this variant of the invention in the form of a motor driven by a sprocket 53. The sprocket 53 is also within the lintel 51 and thus above the passage height 52. The sprocket 53 is engaged with the chain 4 and can open and close the gate by its rotation.

In the vicinity of the sprocket 53 and this approximately opposite the retaining roller 44 is provided, so that the hinges 31, 32 run with the drive means 4 when opening and closing the gate between the sprocket 53 and the retaining role.

The arrangement described with reference to the figures works as follows:

The chain 4 is connected via an engagement with the sprocket 53 and serves to drive the entire door leaf 1. The drive of the sprocket 53 by means of a motor, not shown. The door leaf 1 consists of a plurality of door leaf segments 2, wherein a plurality of these Torblattsegmente 2, and preferably all Torblattsegmente 2, are connected to the chain 4. Preferably, each Torblattsegment 2 is individually secured to the chain 4, each with a hinge pin 5.

The static weight forces as well as the dynamic forces occurring during operation are thus transmitted approximately uniformly to the respective door leaf segment 2 attached to the respective connecting points formed by the chain 4 and the hinge pin 5. The total force therefore no longer has to be absorbed by the lowermost door leaf segment, but rather is distributed as evenly as possible to the entire door leaf 1.

The forces F ₁ , F ₂ required for lifting the individual door leaf segment ₂ (FIG. FIG. 9 ) occur at the contact points of the connecting portion 23 with the Torblattsegment 2 and are mainly transmitted from the chain 4. The hinged haulage 31, 32 serve only to articulate the individual Torblattsegmente 2 together. Due to the special suspension of the individual hinged harbors 31, 32 on the hinge pin 5, enter the Hinge picking 31, 32 themselves, especially in the area of their holes 21, 30, only small forces, which are small to negligible compared to the forces required to lift the door leaf 1 forces F ₁ , F ₂ .

The common connection between the chain 4, the hinge pin 5 and the individual hinge pickups 31, 32 also requires that the chain 4 and the individual hinge trucks 31, 32 move substantially together. The elongated holes 30 are used here in particular to exclude a static overdetermination of the system and so compensate for tolerances or changes in length between the chain 4 and the hinge pickups 31, 32.

It is advantageous if the hinge pins 5 in the upper half of a Torblattsegments 2, and in particular, as in the Figures 3 . 4 and 9 shown, are arranged in the region of an upper edge 36 of the door leaf segment 2. Thus, the individual Torblattsegmente 2, following the gravity, vertically downwards.

A load change occurs in the chain 4 and the Torblattsegmenten 2 only above the sprocket, that is in the region of the lintel 51, on, in which the door leaf 2 stored in the open state, that is rolled up, which act when rolling up the door leaf between the door leaf segments Tensile and compressive forces are lower than those when lifting the door leaf 2 in the passage area.

The recess 6 formed in the hinge fittings 31, 32 serves for stable lateral guidance of the chain 4 and for protecting the chain 4 against external influences. The arrangement of the chain 4 in the recess 6 also leads to a compact design, which is further favored by the fact that the chain 4 used in the hinge garnishes 31, 32 is disposed between the door leaf segments 2 and a guide roller 12, wherein the hinge pin 5 at the same time Axis for this guide roller 12 can serve.

The provided between the chain 4 and the recess 6 damper 43 thereby reduces the noise during the movement of the door leaf 1, which may occur due to small movements of the chain 4 and the hinge lures 31, 32. Another source of noise that the damper 43 counteracts is the engagement of the sprocket 53 with the chain 4.

This compact design results in that the frame width B _Z can be reduced compared to the prior art. By saving the frame width, the passage width of the door can be increased.
