Description

The invention relates to a roller door, in particular a high-speed industrial door, with a gate opening covering the door leaf, which is guided in lateral guides and, for example, as a lamellar armor, flexible curtain, etc. is formed.

Such roller doors are widely known in practice and proven for a long time. They serve as conclusion for openings of most different kind in the private and commercial area. The door leaf is hereby wound in the course of the opening movement in the area of the lintel or guided against the other winding layers without contact in a round spiral or an elongated spiral. The latter embodiment is used in particular for industrial purposes, since this high movement speeds can be achieved with a long life and reliability.

Such high-speed industrial doors have proven to be excellent for a reliable conclusion of highly frequented door openings. Due to the often achieved high operating speeds of 3 m / s and more, it is usually possible to close such industrial doors between two consecutive passes with a forklift or the like and so protect against weather, drafts or loss of air-conditioned atmosphere in a room. However, significant design efforts are needed to design a door system to withstand the dynamic loads associated with these high speeds over time. In particular, a low-friction and precise guidance of the door leaf is necessary.

The German patent applications DE 40 15 214 A . DE 40 15 215 A and. DE 40 15 216 A show examples of such roller doors, in which the door leaf is formed from a plurality of bendable interconnected aluminum slats. To this slats hinged bands are placed, in addition, rollers are arranged in the hinge region of this hinge straps, which are guided in lateral guide rails of this industrial door. These guide rails are deflected in the upper region of the door opening to the inside of the door, so that the door leaf is present in the open position of this industrial door as an elongated winding in the area of the lintel, the individual lamellae, however, are mounted without contact to each other. The bottom-side conclusion of this known door leaf forms a closure element, which is usually provided on the bottom with a sealing lip or the like.

Another example of such a high-speed industrial door is from the DE 199 15 376 A1 in which the lamellae are made of extruded plastic such as GRP or PMMA. These can therefore be designed to be transparent completely or even only in a partial area. According to the construction of an industrial door described in this prior art, the door leaf is received in the open position in a spiral portion with a continuously curved spiral shape in the lintel area. The design of the door leaf with wholly or partially transparent slats has the advantage that even when the door is closed, a view of the other side of the door is possible. This can be a forklift driver z. B. check before opening the door, whether the further track on the other side is free.

Finally, the so-called "Schnellauf Turbo-Rolltor STR" by the applicant is known from practice. The door leaf of this industrial door has a flexible curtain which is fixed to a plurality of stiffening profiles, each of which extends transversely to the lateral guides extending over the door leaf and two hinge hinge hinges associated therewith combines. The stiffening profiles thus form, together with the hinge straps, a type of supporting framework which provides the mechanical stability of the door leaf. On the other hand, the flat finish is made here by the flexible curtain, so that this door leaf is characterized overall by a low weight. As in the already discussed known construction methods of industrial doors, this door leaf is thereby guided on both sides by means of rollers acting on the hinge members in lateral guides and can be guided without contact in a spiral or in an elongated winding in the lintel area. Therefore, this industrial door can be operated at very high speeds of, for example, 4 m / s. Since the curtain is also fixed in this known from practice industrial door to each reinforcement profile by means of a piping, which engages in an undercut groove on the associated stiffening profile, buckling of the curtain is reliably prevented, for example under a wind load. In addition, this curtain can be divided into individual Behangssegmente, so that portions of the door leaf can be designed to be transparent to allow the above-mentioned effect of insight into the present behind the closed gate area.

However, all these known designs of roller doors have the disadvantage that they are often damaged in collisions, for example with a forklift or the like so that they can be used only limited or not at all. This is particularly the case when the speed of movement of the door is very high and therefore is not always appreciated by the leaders of passing the gate opening vehicles. Most endangered here is the often attached at the bottom end of the door leaf closure element, which is just hit when not sufficiently open door leaf or can meet during the closing process on objects present in the Torblattebene. While the latter problem case by arranging a security system in the manner of a gate light grid, as for example from the DE 197 39 543 A and the DE 197 39 544 A is known, can avoid a collision by laterally arriving vehicles is not always avoidable.

The result of such a collision is then usually a deformed or broken closure element, wherein the terminating element adjacent plastic or aluminum slats or a sub-segment of the flexible curtain and individual reinforcing profiles in the well-known from practice fast-turbo rolling shutter STR can also be damaged , These elements are then destroyed and need to be replaced, which is associated with a certain staff and time. In addition, corresponding spare parts often have to be supplied first, so that the roller door can temporarily produce a sufficient conclusion for the door opening.

In addition, it is in conventional roller doors with flexible hangings, such as those in the German patent applications DE 43 13 062 A1 and DE 43 13 063 A1 EP 0621 393 A1 are described, known on both sides of the end profile to provide a flexible guide member which engages loosely in the lateral guides tabs and guided there. In addition, the closure element is formed in this known roller door made of a plastic with lower flexural rigidity and high elastic deformability at sufficiently high impact resistance, so that it can be deflected elastically at a force perpendicular to the door leaf level. If this deflection exceeds a certain extent, this then leads to the flexible guide elements finally becoming disengaged from the lateral guide rails and the terminating element thus emerging altogether from the guide. A fault routine makes it possible in this known roller door, that the door leaf is then automatically raised and automatically re-threads on a funnel-shaped extension at the upper end of the guide rail. Since the closure element is particularly well suited due to the mentioned advantageous material properties to such outer In order to withstand influences nondestructively, a further operation of this known roller shutter is usually possible without any problems.

However, this known collision protection device limits, since the terminating element can not be arbitrarily "soft" formed, because otherwise it would not be able to fulfill its purpose as a stiffening element. From a certain degree or a certain frequency of collisions, destruction also occurs here. In addition, this is from the DE 43 13 062 A1 and DE 43 13 063 A1 known roller door for various reasons not for a fast-paced operation. Thus, the curtain is held only loosely in the lateral guide rails, so that it can emerge from the vertical guides of the door opening at larger wind forces or other manual actions and indefinite load cases arise. However, especially for the fast-start operation, it is necessary for the door leaf to be guided precisely and reliably in the lateral guides, which is conventionally made possible by the rollers on the hinge members explained at the outset. Only by such a precise, low-friction and also beruessngsfreie leadership of the door leaf, it is possible to reliably absorb the dynamic loads occurring at such high speeds can. The one from the two documents DE 43 13 062 A1 and DE 43 13 063 A1 Known collision protection has thus proven to be good for a roller shutter with flexible curtain, which is operated at speeds of up to 2 m / s; however, it is not suitable for use in a high-speed industrial door.

From the WO 96/05399 a ceiling sectional door has become known with a door opening covering the door leaf, which is guided in lateral guides. In this case, the door leaf is subdivided into a subarea that extends in the direction of movement of the door in a subarea facing a footprint of the door such that an edge part guided in lateral guides is present on both sides and at least one middle part extends between the two edge parts, which is releasably attached to the edge parts is held. In this case, the door leaf is further guided on both sides by means of rollers in the lateral guides, wherein it has a bottom-side closing element and the door leaf a hinge means is arranged, by means of which at least the closing element from the Torblattebene is deflected. The hinge device is configured in each case between the individual sections horizontally arranged hinges. Furthermore, the swing-out middle part is again divided by a horizontal hinge means into mutually pivotable section sections.

Thus, there is a need for a roll-up door, in particular a high-speed industrial door, which is not necessarily damaged in the event of a collision so far that parts must be replaced and a functionality is thus temporarily limited.

The invention is therefore the object of developing a roller shutter of the generic type such that the door leaf is less prone to destruction of elements on the door leaf in external events such as collisions with a forklift, collisions erfaβt and appropriate measures can be initiated.

This object is achieved by a roller shutter with the features of claim 1

The invention thus proposes a completely new construction insofar as the door leaf is first formed in several parts in a partial area, wherein these are in the direction of movement of the roller door extending parts against each other from the Torblattebene deflected. Thus, it is possible that the usually affected by a collision middle part of the door leaf of an external influence can escape. Therefore, the functioning of the door leaf affecting damage can be effectively avoided. To restore the final effect of the door leaf, it is then sufficient to return the pivoted center part back into the plane of the adjacent edge parts and to restore the retaining connection.

In addition, the door leaf remains in accordance with the invention reliably guided in the case of a collision in the lateral guides, since the two edge parts are not deflected with the middle part. The functionality of the roller shutter according to the invention is thus given even after a collision.

Furthermore, the roll-up door according to the invention can be provided with little constructive effort and without impairing the conventionally achieved running properties. It has a reliable collision protection, which is why it reacts insensitive to external influences and the risk of damage to the door leaf is significantly reduced.

The multi-part design of a door leaf in the lower part of the invention can be realized in principle on all known Rolltorsystemeen, so that the invention is versatile.

Further, the door leaf of the roll-up door on both sides of a hinge strip with a plurality of bendable interconnected hinge members, which are guided by rollers in the lateral guides, wherein the door leaf has a bottom-side closure element, and wherein the door leaf adjacent to the hinge hinge on the lateral guides opposite side at least in the region of the closure element, an additional hinge means is arranged, which is releasably connected to the respective adjacent hinge band and with which at least the closure element relative to the hinge bands from the Torblattebene is deflected.

Thus, a completely new construction is proposed insofar as the first time a kind of double hinge assembly is provided at least on the closure element The hinge straps are still reliably guided in the lateral guides, so that the mostly desired Schnellaufeigenschaften are still reachable. In addition, however, the additional hinge means is designed deflectable relative to the adjacent hinge band, so that the closure element of an external impact such as a collision of a forklift can dodge. An impairment of the functionality of the closure element damage can thus be effectively avoided. A restoration of the operation of the door leaf is then possible by merely returning the closure element in the plane of the door leaf, without the need for tools or replacement parts would be required.

The roller shutter according to the invention can thus provide a reliable collision protection with little design effort and without affecting the conventionally known and frequently required Schnellaufeigenschaften so that it reacts much less sensitive to external influences and the risk of destruction of individual elements of the door leaf is drastically reduced.

In addition, the roll-up door according to the invention has a control unit with a sensor, wherein a deflection of the closure element or the adjacent thereto portion of the door leaf relative to the Torblattebene is detectable by the sensor, and wherein the control unit initiates a fault routine in response thereto. This has the advantage that a collision is thus detected immediately, and at the same time fully automated appropriate measures can be taken to keep damage to the door leaf or hazards to persons as low as possible.

Advantageous developments of the rolling door according to the invention are the subject of the dependent claims.

Thus, the intentional hinge device can also be designed such that, in addition to the closure element, a partial region of the door leaf extending thereon and extending over one or more of the hinge elements can be deflected out of the door leaf plane with respect to the hinge bands. This has the advantage that in a more severe impact or impact, which includes not only the closure element but also adjacent lamellae or segment areas, also the advantage of the invention can be used that the affected elements of the door leaf dodge by swinging out of the Torblattebene , The collision protection of the door leaf is thus improved and the industrial door according to the invention even less sensitive to external influences.

If the additional hinge device is designed in such a way that the closure element or the adjoining partial region of the door leaf can be deflected out of the door leaf plane on both sides, the collision protection according to the invention can be effective for influences from both sides of the door leaf be, whereby the functionality of the roller door according to the invention further improved.

In this case, the additional hinge means may be fixed by means of at least one latching connection relative to the respective adjacent hinge strap. Thus, an unintentional deflection of the closure element or of adjoining partial areas of the door leaf from the door leaf level, for example under wind load, can be reliably avoided. The functonality of the roller shutter according to the invention can thereby be further improved and, in particular, the requirements for a fast-start operation can be fulfilled even more reliably.

In this case, the latching connection can be made by a resiliently biased locking pin which engages in a complementary formed locking part. Such a Formgehemme is familiar to the expert and can be provided with little design effort. It is also reliable and clearly defined in its function.

If, in addition, the pretensioning force of the arresting pin is adjustable, the limit force of the locking connection can also be set exactly. This can be ensured that the deflectable elements of the door leaf on the one hand not already come out due to wind load from the connection with the adjacent hinge and thus cancel the latching connection, and on the other hand, however, in response to a certain impact pulse release of the elements to be deflected the door leaf is possible, so as to be able to reliably prevent damage to the same.

Alternatively, it is also possible that the additional hinge means is held by means of at least one magnetic device on the respectively adjacent hinge band. Also, on the one hand, a reliable protection against prevent a deflection purely due to a wind load and still produce a correspondingly large shock pulse destructive deflection of the closure element, etc. In this embodiment, it is further advantageous that the coupling of the additional hinge means to the adjacent hinge strip is non-contact, so that no signs of wear are given here. This can be a particularly long life. A sufficient magnetic effect can be produced in particular by electromagnets, which also have the advantage that the corresponding magnetic forces are adjustable, ie, an adjustment of the holding force of the additional hinge device on the hinge is possible.

In addition, the industrial door according to the invention may also be provided with a locking device, by means of which the additional hinge means for producing a burglary protection in each case against the adjacent hinge strap is lockable such that a deflection of at least the closure element is prevented. In this way, the Torabschluß can be used when not using the Rolltors for example, over night or over the weekend as a reliable outer finish for an industrial hall, etc. In this case, this locking device may for example be configured with a manually or automatically operable locking pin, so that with little design effort and z. B. by a displacement of the roller door in a state of rest easily the desired barrier effect can be made. In this case, it is usually sufficient if the closure element is locked against the hinge straps, as possibly a possible deflection of adjacent portions of the door leaf then inevitably also substantially prevented, since the closure element then can not be raised.

It is a further advantage if the hinge elements associated with the closing element are each guided in the lateral guides by means of a carriage. As a result, a reliable guidance of these hinge members is also then ensured when the middle part of the door leaf deflected out of the Torblattebene and thus in this area no supporting cross-connection between the two lateral hinge straps is given more. By the carriages, therefore, a corresponding stabilization of the arrangement take place, so that tilting moments can be reliably avoided in the region of these hinge members. This embodiment is also particularly advantageous when the Torblattantrieb via circulating drawstrings, which act in the region of the closure element on the hinge bands. When opening the door, this results in thrust forces, which naturally lead to buckling of the hinge members of the hinge bands, whereby unwanted tilting moments can act on the door leaf. Another cause of such tilting moments may also be that the drawstrings of the door drive does not engage exactly in the plane of the guide rollers. The arrangement of the carriage can be counteracted, since this avoids tilting of the closure member adjacent hinge member by positive engagement. In a purely guided by rollers lower hinge member, however, by the then inevitable tilting unwanted stresses could occur. Due to the arrangement of the carriage in the lateral guides, therefore, the Schnellaufeigenscharten the rolling door according to the invention can provide even more reliable and durable. The arrangement of a carriage has the further advantage that the guide rollers are less heavily loaded on these hinge members when it actually comes to a collision of a forklift or the like with the closure element and thus to a force normal to the direction of movement of the door leaf. The hinge straps are therefore held particularly reliable in this collision-prone area in the lateral guides and thus in the Torblattebene and do not tend to follow the deflection of the closure element. As a result, the reliability and durability of the roller door according to the invention can be further improved.

Further, the control unit in the fault routine can cause an automatic stop of a movement of the door leaf, so that damage to other slats or Torblattsegmente or reinforcing profiles, etc. can be reliably avoided.

It is of further advantage if the control unit initiates an opening movement of the door leaf in the fault routine, possibly following an automatic stop, wherein the industrial gate is further provided with a return device in the region of the lintel, by means of which a deflection of the closure element or the this adjacent portion of the Torblatts is reset. In this way, at the same time a restoration of the functionality of the roller shutter according to the invention can be initiated by means of the fault routine. Since the terminating element, etc., is usually not damaged, since it could avoid the shock, a restoration of the functionality of the roller door according to the invention is possible within seconds.

In this case, the control unit can run the fault routine so that the opening movement of the door leaf is performed with respect to the normal operation reduced speed. This is particularly advantageous in high-speed industrial doors, as this possible hazards near the roller door standing persons or further damage to the door leaf, for example, by the deflected middle part can be avoided even more reliable.

As shown in Fig. 1 has a roller door 1 a door leaf 2, which is held in lateral guides 3. The door leaf 2 contains lateral, respectively arranged in the region of the guides 3 hinges 4 of a plurality of hinge members, of which the hinge members 41a-41e in the further detail, in particular in the FIGS. 2 to 4 are recognizable. In each case two mutually associated hinge members are connected by a transversely to the lateral guides 3 extending stiffening profile 5 with each other, so that the hinge strips 4 with the stiffening profiles 5 form a stable, but bendable framework.

A flexible curtain 6 made of plastic, which is subdivided in the present embodiment into sub-segments 61, 62, 63 and 64, is held by means of a Kederverbindung to the stiffening profiles 5. Since the sub-segment 63 of the curtain 6 is transparent, and the underlying stiffening profiles 5 are in Fig. 1 drawn as visible. How out Fig. 1 Furthermore, it can be seen, the door leaf 2 also has a closure element 7, which is provided on the bottom side with a rubber seal or the like. This construction of the door leaf 2 with the hinge straps 4, the stiffening profiles 5 and the curtain 6 corresponds to the extent already described in the introduction "fast-Turbo-Rolltor STR" of the Applicant, as well as in the German patent application DE 10236648.9 is described, the disclosure of which reference is made in this regard.

How out Fig. 1 It can also be seen that the lower sub-segment 64 of the curtain 6 is recessed in the region of the lower four hinge members 41a-41d of the hinge bands 4 in order not to counteract an evasive movement of a central part of the door panel 2 in the event of a collision.

In Fig. 2 this part of the roller shutter 1 is shown in more detail, wherein Fig. 2 a rear view of the in Fig. 1 at the bottom right present end portion of the door leaf 2 represents. The present on the other side of the door opening end portion of the door leaf 2 is constructed in mirror image. In this rear view according to Fig. 2 next to the hinge 4 a further hinge device 8 can be seen, which runs parallel thereto. In the present exemplary embodiment, this hinge device 8 contains three links 81a-81c, which correspond in their functional dimensions to the adjacent hinge links 41b-41d, ie can be angled relative to one another about the same axes. Finally, a closing strip 71 of the closing element 7 is articulated on the bottom-side nearest link 81a. The bottom-side termination of the closure element 7 forms a rubber seal 72.

As in particular from Fig. 2 can be seen, the hinge member 41e is formed substantially as wide as, for example, the hinge member 41d and the adjacent thereto member 8 1 c together. The hinge member 41e thus provides the transition to the multi-part portion of the door leaf 2 ago.

The end element 7 or the links 81a-81c are pivotable about coaxial with the pivot axes 42 of the hinge members 41a-41d. On the pivot axes 42 rollers 43 are mounted. The rollers 43 are held in a manner known per se in a form-fitting manner in the lateral guides 3 and guide the door leaf 2.

How out Fig. 2 Furthermore, it can be seen, on the lower hinge member 41 a further fastened a holder 44 for a toothed belt drive, not shown. In addition, the lower hinge member 41 a is also provided on the bottom side with a rubber seal 45.

How out Fig. 3 shown in more detail, the hinge means 8 is connected in this embodiment by Formgehemme in the manner of a latching connection with the adjacent hinge strap 4. These form cramps each have an inhibiting pin 82 which is received in a receptacle 83 in the respective hinge member 81a-81c and by means of a spring 84 in the direction of adjacent member 41a-41d of the hinge band 4 is biased. The receptacle 83 has an external thread, by means of which it is held adjustable in a holding hole 85 with internal thread. In other words, the biasing force of the spring 84 can be adjusted by rotating the receptacle 83 relative to the holding hole 85.

The inhibiting pin 82 engages positively in a substantially complementary formed locking part 46 in the member 41a-your. In this way, a possible cancellation of the locking connection is achieved at a certain limit force, this limit force is adjustable by adjusting the receptacle 83 in the retaining hole 85. Since the inhibiting pin 82 is also held positively in the receptacle 83, a loss of the inhibiting pin 82 is not possible even when swung member 81 a. The further latching connections are identical or analogous, also on the terminating element 7 to the hinge member 41a.

The hinge means 8 is, apart from the permanent connection on the upper member 81c to the hinge member 41e connected only by this Formgehemme with the adjacent hinge members 41b-41d. In the event of a collision, the closure element 7 can pivot out of the door leaf plane together with the subregion of the door curtain defined by the three links 81a-81c and thus avoid the stress.

How out Fig. 3 It can also be seen that slide plates 47 and 86, which also have edges with chamfers, are mounted on the mutually facing end faces of the hinge members 41a-41d and the links 81a-81c and the terminal strip 71, respectively. By means of these sliding plates 47 and 86, the provision of a swung-out middle part of the door leaf 2 is facilitated in the Torblattebene.

In Fig. 4 the hinge 4 is still in section along the line AA in Fig. 2 shown. It can be seen that the hinge members 41a-41e each in Seen gate leaf thickness are hinged near a major surface of the door leaf, so that they swing out only in one direction, namely to the curtain 6 out.

In the FIGS. 5 to 7 the further hinge device 8 is shown in more detail. As in particular from Fig. 5 can be seen, the individual members 81a-81c are formed such that their mutually facing surfaces in the pivoting range by a predetermined amount "t" are spaced from each other. Although the pivot axis of the individual members adjacent to the curtain 6 of the door leaf are also present in the hinge device 8, it is thus possible to pivot the hinge device 8 in the opposite direction, as shown in FIG Fig. 7 is shown. With a measure t of, for example, 6 mm, this results in a possible pivoting about 27 degrees per hinge member in the practical example. The dimension "t" can be freely selected depending on the application. The hinge device 8 can thus be swung out of the door leaf plane in both directions.

In the illustrated embodiment, the door leaf is driven by means not shown here drawstrings in the form of toothed belt in a conventional manner, said drawstrings attack on the holder 44 and the door panel 2 for opening the industrial door 1 either up or close the door leaf 2 pull down. The drawstrings are formed circumferentially for this purpose.

As in detail from the perspective view in Fig. 8 can be seen, a carriage 9 is arranged on the lower hinge member 41a, ie in the region of the closure element 7, which has a carrier 91 and four rollers 92 and also cooperates with the lateral guide 3. In Fig. 8 a section of the guide 3 is shown to clarify the facts. The hinge member 41 a is supported by means of the rollers 92 against a movement in the direction of the end strip 71 out. The carriage 9 acts a tilting of the The risk of tilting of the hinge member 41a is, for example, given when deflected central part of the door leaf 2 no cross-connection more to the other side of the gate is present, so that the essentially formed by the two hinges 4 edge portions of the door leaf 2 can no longer be supported against each other. The case occurring in the course of an opening or closing movement of the door leaf 2 further tilting moments can be reliably absorbed by the arranged on both sides of the rolling door 1 carriage 9.

The risk of tilting of the hinge member 41a is also given on the one hand in the course of the opening movement due to the entry of tensile forces on the holder 44, and on the other hand in even greater extent in collisions, since corresponding normal forces act on the main surface of the door leaf 2 at least as long the middle part of the door leaf 2 is still not swung out of the Torblattebene despite application of force. By the carriage 9 such forces can be reliably absorbed, so that damage to the adjacent rollers 43 and / or cooperating with the holder 44 drive is permanently avoided.

In Fig. 9 is shown in perspective view a return device 10 of the roll-up door 1. As can be seen from this, the return device 10 includes two mutually spaced, cooperating rollers 101, which are each mounted by means of a holder 102 in the region of the lintel on a lateral guide 3. The distance between the two rollers 101 corresponds substantially to the thickness of the door leaf 2. In addition, the two rollers 101 are spaced from the lateral guide 3 so that they act on the members of the hinge means 8 to push back this, if necessary, back to the Torblattebene. This is in the course of an opening movement of the Rolltores 1 an automatic return of a swung-center part of the door leaf 2 achievable.

As shown in Fig. 10 the industrial door 1 also has a locking device 11, by means of which the end strip 71 relative to the adjacent hinge member 41a can be locked. For this purpose, the locking device 11 includes a locking pin 111 which is controlled by an electric drive, here an electric motor 112, movable and positively locking to lock in a corresponding recess on the adjacent sliding plate 86 engages the end strip 71.

Furthermore, the industrial door 1 has a control unit, which by means of a sensor 12 (see. Fig. 2 ) detects a deflection of the door leaf 2 from the Torblattebene. For this purpose, the sensor 12 is arranged in the lowermost hinge member 41a and points to the end strip 71. If this is no longer detectable by the sensor 12, a fault routine is automatically triggered, in which the door leaf 2 is stopped and placed in an opening movement.

In addition to the embodiment shown, the invention allows for further design approaches.

It may vary the number of links of the hinge 8 depending on the application. The size of the pivotable from the Torblattebene portion of the door leaf 2 can be adjusted so. In a particular embodiment, only the closure element 7 can be held pivotably on the hinge device 8, so that only the closure element 7 can perform an evasive movement.

The holder of the hinge device 8 on the hinge 4 can also be done in other ways than by means of the described mold inhibitors, such. B. by means of electromagnet. In this case, both the number of Formgehemme and the alternatively provided electromagnets vary and be selected according to the respective requirements. The inhibiting pin can also be mounted in a hinge member of the hinge band 4, while the associated locking part is then arranged in the hinge device 8. In addition, any other type of locking, adhesive or button connection is possible.

Furthermore, it is also possible that the Ausgestaltungsweise invention is applied to a door leaf, which is designed in the manner of a laminated armor. Examples of such lamellar tanks are from the documents DE 40 15 214 A . DE 40 15 215 A . DE 40 15 216 A and DE 199 15 376 A1 known. Another application of the invention is in roller doors with flexible hangings, which are wound in the area of the lintel. These hangings can simply be slit in the direction of movement of the door leaf and, for example, be buttoned together.

In addition, it is also possible that the drive of the door leaf does not take place via tension bands and thus the introduction of force is not carried out on the closure element 7. Instead, the drive can also attack at the upper end of the door leaf and thus pull the door leaf when opening in its storage position above the gate lintel, but push when closing. Examples of top-powered door leaves are known in practice. In this case, can also be dispensed with the carriage 9 under certain circumstances, since the tilting moments occurring at the lower hinge member 41a are significantly reduced for this drive mode.

Instead of the carriage 9 and a sliding block on the lower hinge member 41 a may be arranged. This is then preferably made of a lubricious material, in particular PTFE or the like, and acts as well as the rollers 43 positively with the guide 3 together. The sliding block would be formed parallelepiped and would thus one with the guide. 3 cooperating sliding surface in a plane parallel to the extension of the guide 3 produce, so that a tilting of the hinge member 41a is thus counteracted by positive engagement in clearance fit.

The restoring device 10 may instead of the rollers 101 also include sliders on which the deflected middle part of the door leaf 2 slides along and is thereby returned to the Torblattebene again.

In order to avoid damage to the edge parts of the door leaf, they are usually formed relatively narrow relative to the central part. Moreover, it is also possible to design several deflectable middle parts on the door leaf, which may be useful especially for large door widths.

The locking pin 111 may alternatively be powered by a different electrical means than the solenoid 112, or purely mechanically. In addition, the locking device 11 and / or the sensor 12 may also be present in another hinge member or in a member of the hinge device 8.

The hinge straps 4 and / or the hinging devices 8 can also be designed as a relatively flat hinge device placed on the door leaf 2 on a main surface.
