Description

The invention relates to a locking arrangement for a door leaf integrated in a door leaf of a sectional door and with respect to a pivoting axis in a closed position of the door preferably approximately in the direction of gravity pivoting and at least two with respect to an approximately perpendicular to the pivot axis extending tilt axis against each other tiltable door leaf elements exhibiting door leaf, wherein at least two door leaf elements a locking device is associated with at least one adjustable between a locking position and a release position locking element, at least two locking devices is assigned a common actuatable for adjusting the locking elements actuation device, and the actuating device is coupled via a connecting device to the locking devices, wherein the connecting device at least two in the direction associated with the pivot axis successive door leaf elements and preferably e fastened thereto, each extending in the direction of the pivot axis, slidably held in the direction of the pivot axis with respect to the door leaf elements and with respect to the tilting axis against each other tiltable coupling rods and a equipped with such a locking arrangement sectional door.

Door leaves of sectional doors have a plurality of relative to each other extending tilt axes against each other tiltable Torblattelementen. Such sectional doors are used in the form of garage doors and in the form of industrial doors for closing passages in garages and industrial halls. In both cases, the door leaf in the closed position is usually arranged approximately in a vertical plane and in the open position above the head approximately in a horizontal plane. To guide the Torblattbewegung between the closed position and the open position are usually guide rails with an approximately rectilinear and approximately parallel to the side Torblattrand in the closed position extending vertical portion, an approximately rectilinear and approximately parallel to the side Torblattrand in the open position extending horizontal portion and the two rectilinear Provided sections interconnecting arcuate portion.

The mobility of the door leaf along the arcuate portion can be ensured because the door leaf elements of the door leaf are mutually tiltable connected to each other about perpendicular to the guide rails extending tilt axes. For this purpose, usually hinge-like connecting elements between the door leaf elements are used.

If a person wants to leave a space locked with such a sectional door, the gate door having a width of 5 m or more in industrial doors must be moved as a whole from the closed position to the open position. This not only means a considerable burden on the mechanical elements of the door leaf, but is also associated with a considerable amount of time. To solve these problems has already been proposed to integrate a door with a pivotable about an approximately perpendicular to the tilting axes and in the closed position of the door leaf approximately in the direction of gravity pivot axis with respect to the adjacent door leaf elements door leaf in the door leaf. Such a "wicket door" allows leaving the closed space with the door leaf without opening the door leaf as a whole. Rather, only the door leaf integrated in the door leaf must be opened by pivoting about the pivot axis. To enable an opening movement of the door leaf with the door leaf integrated therein, the door leaf of such constructions consists of a plurality from respect to each other with respect to each other tiltable door leaf elements with respect to collinear axes to the tilt axes.

To ensure the burglary security required in the door leaf closing position not only one of the movement of the door leaf from the closed position into the open position counteracting latch assembly, but also in a locking position of a pivotal movement of the door leaf about the pivot axis counteracting latch assembly must be provided so that penetration into The closed with the door leaf space is not possible through the wicket door. Such latch assemblies usually have a recorded in a door leaf element lock, the locking element is received in the locking position in a recess which is provided in the door leaf element facing edge of the adjacent Torblattelementes.

In view of the fact that door leaf elements and door leaf elements conventional gates of the type described above usually consist of metal shells with a wall thickness of 1 mm or less, between which an insulating material can be arranged to improve the burglary has already been proposed, the castle receiving door leaf element and to equip the adjacent door leaf element with reinforcing elements, which complicate a violent opening. However, it has been shown that a satisfactory burglar resistance is not achievable with these measures.

In view of these problems in the prior art is in the DE 20 2005 007 416 A1 an improvement of the known locking arrangement proposed, in which the locking arrangement has at least two locking devices, each of which counteracts in the locking position of a pivoting movement of a respective door leaf element with respect to a be-adjacent Torblattelement. In the locking arrangement described in the cited document, the locking elements of the locking devices are realized in the form of thrust bolts, which are to be operated individually. In view of the associated with the operation of the individual locking elements time expenditure is often observed that only one of the locking elements is actually brought into the locked position, so that a satisfactory burglary is indeed not guaranteed on a regular basis. A simple operation of bar arrangements with two or more locking devices is by a in the EP 1 722 052 B1 achieved described improvement of the known latch assemblies. In the latch assembly described in this document according to the preamble of claim 1, the individual locking devices are coupled via a linkage to a common actuating element. This linkage comprises a plurality of coupling rods, each of which is slidably fixed to a door leaf member in the direction of the pivot axis, wherein tilting of the door leaf elements equipped with the coupling rods with respect to the tilt axes while ensuring a reliable power transmission between the actuator and the latch means by elastic connecting elements between the individual coupling rods is made possible. These elastic connection devices can according to EP 1 722 052 B1 be realized by cylindrical tension springs which are attached to adjacent coupling rods.

However, it has been found that the installation of corresponding bolt assemblies is connected to the wicket doors of a sectional door with a considerable effort, because initially the coupling rods to the individual. Door leaf elements must be attached and coupled to the corresponding locking devices, after which then a tilting of the door leaf elements with respect to the tilting axes enabling connection between the coupling rods is to be established.

In the face of this shortage was in the DE 10 2008 039 746 A1 a locking arrangement has been proposed in which the connecting device has at least one continuously extending over the entire length between the actuating device and at least one locking device and generally with respect to its longitudinal axis and parallel to the tilting axis extending bending lines bendable, in particular elastically bendable connecting element. According to the cited document, sectional doors equipped with such locking arrangements can be produced by forming a recess designed for receiving a locking device and / or an actuating device in a core of the door leaf element arranged between two shells in a first method section, then a covering element on the one with the recess equipped edge of the door leaf element fitted and then a locking device and / or an actuating device in a recess of the cover introduced and then a connecting element is inserted into a preferably groove-shaped recess in the core. Although in this way a significant simplification of the assembly of bolt assemblies for integrated in a sectional door leaf wicket doors is achieved, it has been found that still a considerable amount of time is required for this assembly.

In view of these problems in the prior art, the present invention seeks to provide a development of locking arrangements for wicket doors of sectional doors, which ensures a satisfactory burglary with simple installation.

According to the invention this object is achieved by a development of the known locking arrangements, which is characterized essentially in that facing axial ends of the coupling rods in the closed position of the door panel for transmitting a push and / or pull movement in the direction of the pivot axis are assigned to each other engageable coupling surfaces.

This invention is based on the knowledge that it is not necessary to ensure the reliability of a plurality of locking devices having latching arrangement, the individual door leaf elements associated sections of the actuator connecting the locking devices connecting means permanently together. Rather, it is sufficient to ensure functional safety when thrust and / or tensile forces in the closed position of the door leaf can be transmitted via suitable coupling surfaces associated with the coupling rods, wherein the coupling surfaces are preferably formed on the Koppel rods themselves. These coupling surfaces have a surface normal, which has a parallel to the longitudinal axis of the coupling rods component, and can be completely dissolved without impairing the reliability of the latch assembly in the course of a Torblattbewegung along an arcuate portion of a predetermined path, so that the contact between the coupling rods completely will be annulled. The coupling rods of latch arrangements according to the invention can be fastened to the individual door leaf elements or to the door leaf elements adjacent to the individual door leaf elements. Within the scope of the invention it has However, proved to be particularly advantageous when the coupling rods are held on the door leaf elements themselves.

The door leaf elements with the coupling rods' held thereon can be connected to each other as pre-assembled modules on site for the production of integrated in a door leaf door leaves, without that still a connection between the individual coupling rods must be made. It is therefore no longer necessary when using latch arrangements according to the invention to attach the connecting device of the latch arrangement to the finished assembled door leaves. As a result, on-site assembly is significantly simplified because a substantial part of the assembly work involved in the production of the preassembled assemblies consisting of door leaf elements, coupling rods and possibly locking devices, factory, i. if necessary by machine, can be performed.

In the context of the invention is also intended to the use of bolt arrangements in which the individual coupling rods are biased with possibly integrated in the preassembled modules biasing means in a locking position corresponding position and then on the coupling surface only one of the biasing force counteracting tensile or compressive force between the coupling rods must be transmitted to effect unlocking of the locking assembly. For reasons of cost and with a view to further improving the desired reliability, it has proved to be advantageous if at least one axial end of at least one coupling rod at least two opposing coupling surfaces are assigned, one of which for transmitting a thrust and the other for transmitting a tensile force is designed for an adjacent coupling rod. In this embodiment of the invention can be dispensed with the use of the individual coupling rods associated biasing elements. Furthermore, an increase in the reliability is achieved because the use of two mutually opposite coupling surfaces allows reliable positioning of the coupling surfaces of a coupling rod with respect to the coupling surfaces of the adjacent coupling rod.

In a particularly preferred embodiment of the invention, a reliable positioning of the Köntaktflächen adjacent coupling rods to each other is achieved in that at least one contact surface is formed by a connected to the coupling rod, in particular integrally executed with an end piece, preferably from one of the door outer side facing the boundary surface Coupling rod or the end piece in a direction perpendicular to the plane defined by the tilting axis and the pivot axis extending direction extending recess and / or bore, in the at least in the closed position of the door leaf an axial end portion and / or provided at the end portion and in a projection extending perpendicular to the direction through the tilt axis and the pivot axis extending plane extending projection, in particular in the form of a conical pin, the adjacent coupling rod or this zugeord Neten, in particular integrally executed therewith end piece is at least partially included.

In this embodiment of the invention it is achieved that end pieces of the coupling rods are hooked together in the closed position of the door leaf by the end portion of the one end piece or the projection is received in the recess or bore of the other end piece, at the same time by the alignment of the recess is ensured in a direction perpendicular to the tilting axis and the pivot axis spanned plane extending direction that the recorded in the indentation end or the projection received in the bore when passing through the arcuate portion of the predetermined path in the course of an opening movement or closing movement of the door leaf from the Dent or bore can be swung out without hindering the opening or closing movement. In the closed position of the door leaf, both tensile forces and compressive forces between the coupling rods can be transmitted via the end region or projection received in the indentation or bore. The insertion of the end region or projection into the indentation or bore can be reliably ensured when the indentation or bore tapers in the insertion direction so as to form an extended insertion area facilitating the insertion of the end region or projection to be accommodated therein.

In the last described embodiment of. Invention, a particularly good reliability is achieved when the indentation at its the axial end of the tail facing edge or at its adjacent coupling rod edge facing two in the direction of the tilt axis spaced guide regions between which at least in the closed position of the door leaf a in The end region accommodated in the recess is arranged with the outside of the indentation arranged remainder of the coupling rod or the end piece associated therewith connecting portion, said in the indentation recorded end portion in the direction of the tilt axis has a greater width than the connection region, so that at least one of the connection region facing Coupling surface of the received in the indent end portion of at least one coupling surface of at least one indentation bounding the guide region can be applied, so as to transmits tensile forces between the coupling rods to be able to. By including the connecting portion between the guide portions, accurate positioning of the coupling surfaces of adjacent coupling rods is enabled, and insertion of the connecting portion between the guide portions can be facilitated as the distance between the guide surfaces in the insertion direction decreases to facilitate insertion of the connecting portion to provide extended estuarine area between the guidance areas.

A further improvement in the functional reliability of inventive latch arrangements can be achieved if at least one coupling rod is held against rotation relative to the door leaf element. For this purpose, the coupling rod can be slidably received in the axial direction with respect to rotations about the longitudinal axis in a guide device fixed on the door leaf element. The desired anti-rotation is made possible by each coupling rod shape, which has a deviating from the circular disk shape radial cutting surface. Furthermore, the coupling rod may have a guide pin received in a guide slot of the guide device extending in the direction of the pivot axis, or the guide device may comprise a guide pin received in a guide slot of the coupling rod. However, in terms of manufacturing technology, it has proven to be particularly simple when the coupling rod has a polygonal cross-sectional area, in particular has a square or rectangular radial sectional area. By the torsion-proof Guiding the Kopplurigstange is ensured that the indentation or bore is reliably aligned in a direction perpendicular to a plane spanned by the tilting axis and the pivot axis extending direction, so as to achieve a trouble-free opening or closing movement of the door leaf.

The coupling of the coupling rod to the locking device can be carried out in the context of the invention, for example, characterized in that the Kopptungsstange passes through a locking device and the pushing movement of the coupling rod is suitably transmitted by a arranged in the locking device transfer device to the locking element. However, manufacturing technology and assembly technology, it has proved to be particularly advantageous if at least one coupling rod extending the coupling rod in the radial direction, preferably arranged outside the guide rod designed for non-rotating guidance of the coupling rod and movable in the axial direction with the coupling rod entrainment means for coupling the coupling rod to the Latch device is assigned. In this embodiment of the invention, no special adaptation of the locking device to the coupling rod is required. Rather, the coupling rod can be arranged completely outside the locking device, wherein the movement of the coupling rod via the coupling rod in the radial direction widening, that is extended in a plane perpendicular to the longitudinal axis of the coupling rod extending carrier device is transferred to the locking device.

In a further preferred embodiment of the invention, the entrainment device may comprise at least one entrained by the coupling rod and can be coupled to an actuator of the locking device driver element. In this case, the actuator may have a disclosed outside of a housing of the locking device plunger, on the end face a boundary surface of the driver in the course of a push and / or pull movement of the coupling rod can be applied, which is also thought in particular, the axial movement of the plunger of the locking device to convert into a pivoting movement of a locking element and / or a linear movement of the locking element in a direction perpendicular to the pushing movement of the coupling rod direction by means of a suitable transducer device.

A further simplification of the assembly according to the invention latch arrangements can be achieved if the driver has a fixed to the coupling rod and with respect to the driver element in a plane perpendicular to the pivot axis or perpendicular to the longitudinal axis of the coupling rod movable transmission element for transmitting an axial movement of the coupling rod on the driver element , By floating in a direction perpendicular to the longitudinal axis of the coupling rod bearing the coupling rod with respect to the driver element by means of the transmission element alignment errors can be compensated in a direction perpendicular to the longitudinal axis of the coupling rod direction without affecting the reliability of a latch assembly according to the invention. For this purpose, the coupling rod can pass through the transmission element and optionally with a clamping device, such as a transmission element passing through the clamping screw to be attached to the coupling rod. In this case, the clamping screw passes through the transmission element in a direction perpendicular to the longitudinal axis of the coupling rod direction and lies with its end face on the transmission element passing through section of the coupling rod.

A further increase in the reliability of inventive bolt arrangements can be achieved if the entrainment means fixed with respect to the door leaf element, in particular attached to the door leaf element guide assembly for guiding and possibly limiting the movement of the driver element and / or the transmission element in the direction of the pivot axis or in the direction of the longitudinal axis having the coupling rod.

If the guide arrangement also has a guide plate which also serves to fasten the locking device with respect to the door leaf element, precise positioning of the entrainment device relative to the locking device can be achieved with the aid of the guide device. For this purpose, the guide plate may have a guide slot, can engage in the guide projections of the driver element and / or the transmission element.

As can be seen from the above explanation of latch arrangements according to the invention, a sectional door according to the invention comprises a door leaf, one in the door leaf integrated door leaf, designed for guiding the door leaf movement between an open position and a closed position guide rail assembly having an arcuate portion between two rectilinear portions and a latch assembly according to the invention.

In FIG. 1 two successive door leaf elements 10 and 20 are shown in the direction of the pivot axis of the door leaf, each of which can have sheet metal shells with a wall thickness of less than 1 mm, between which a foam core is received. The edges of the door leaf elements 10 and 20 facing the adjacent door leaf elements are covered, for example, by cover elements 12 and 22 designed as extruded aluminum profiles, for example, in order to protect the foam core accommodated between the sheet metal shells and to stabilize the door leaf element. In the cover 12 a in the foam core of the door leaf element 10 extending a locking device and an actuator of a latch assembly according to the invention forming lock 14 is inserted. In the cover 22 of the door leaf element 20 is inserted through the operable by the lock 14 locking device 24 of a latch assembly according to the invention. The locking device 24 extends from the cover 22 in the recorded between the metal shells of the door leaf element 20 foam core. From a comparative analysis of the FIGS. 1a ) and 1b ) shows that the locking device 24 is tilted when passing through an arcuate portion of the door leaf movement leading track with respect to the lock 14.

The transmission of a serving for actuating the locking device 24 movement of the lock 14 on the locking device 24 while ensuring the tilting of successive door leaf elements allowing connection means will be described below with reference to the FIGS. 2 to 4 explained in detail. Thereafter, the connection device two coupling rods 110 and 210, of which the coupling rod 110 is slidably mounted on the door leaf element 10 with respect to the door leaf element 10 in the direction of the pivot axis of the door leaf. For this purpose, the coupling rod 110 according to the sectional view in FIG. 2 received in a guide channel 16 of the cover 12. The guide channel 16 is formed integrally with the cover 12 and has a rectangular cross-section whose shape and size is adapted to the rectangular cross-section of the coupling rod 110. In this way, a rotationally secure guidance of the coupling rod 110 during a movement in the direction of the pivot axis, ie perpendicular to the plane of the paper in FIG. 2 , reached. Likewise, the coupling rod 210 is slidably received in a rectangular guide channel of the cover 22 in the direction of the pivot axis and fixed with respect to the door leaf element 20.

According to FIG. 3 For example, the coupling rod 110 has an end piece 112 designed in one piece therewith and facing the coupling rod 210, while the coupling rod 210 comprises an end piece 212, which is likewise embodied in one piece therewith and faces the coupling rod 110. How very clear in FIG. 4 it can be seen, the end pieces 112 and 212 in aligned arrangement of the coupling rods 110 and 210 interlocked, so that a push and a pulling movement of the coupling rod 110 can be transmitted to the coupling rod 210. For this purpose, the coupling rod 110 end face side and in the in FIG. 4 illustrated embodiment, upwardly facing coupling surfaces 114 which abut 110 and 210 at coupling surfaces 214 of the coupling rod 210 in aligned arrangement of the coupling rods. To transmit a pulling movement, the coupling rod 110 further the coupling surfaces 114 opposite and in the in FIG. 4 illustrated embodiment, downwardly facing coupling surfaces 122, which can be brought into abutment against coupling surfaces 222 of the end piece 212 of the coupling rod 210. In order to form the coupling surfaces 122, the end piece 112 has a plane extending in a plane perpendicular to a plane defined by the pivot axis and the tilting axis between successive door leaf elements and in the plane shown in FIG FIG. 4 illustrated embodiment of the outside of the coupling rod 110 outgoing indentation 120, the upper edges of which form the coupling surfaces 122.

In the recess 120, a lower axial end portion 220 of the coupling rod 210 and the end piece 212 is received. The upper boundary surfaces 222 of the end region 220 form coupling surfaces which, when tensile forces are transmitted from the coupling rod 110 to the coupling rod 210, interact with the coupling surfaces 122 at the upper edge of the indentation 120. Due to the lower boundary surface of the end region 220 and the lower edge of the indentation 120, further coupling surfaces serving for transmitting thrust forces from the coupling rod 110 to the coupling rod 210 can be formed.

The end region 220 of the coupling rod 210 is connected via a connection region 230 to the region of the coupling rod 220 exposed outside the coupling rod 110. The connection region 230 is accommodated between two guide regions 130, which are spaced apart from one another in the direction of the tilt axes, at the upper end of the coupling rod 110. This allows a space-saving entanglement of the coupling rods 110 and 210, which allows the transmission of tensile and shear forces from the coupling rod 110 to the coupling rod 210.

At the same time, this movement enables the door leaf or the door leaf integrated in the door leaf to be moved through an arcuate area of a predetermined path. The movement is in FIG. 5 illustrated, wherein the end portion 220 of the coupling rod 210 in the course of Torblattbewegung along an arcuate portion of the path predetermined by guide rails from the recess 120 at the upper end of the coupling rod 110 pivots out. This is made possible by the alignment of the indentation 120 in a plane perpendicular to the plane spanned by the tilting axes and the pivot axes. In the presentation according to FIG. 5 is the latch assembly in an unlocked position, from which they by transferring tensile forces from the coupling rod 110 on the coupling rod 210 in an in FIG. 6 shown locked position can be transferred. In this position, the transition region between the coupling rods 110 and 210 is offset with respect to the tilting axis, so that the end portion 220 of the coupling rod 210 is further pivoted out of the indentations 120 of the coupling rod 110 and the end piece 112 during a Torblattbewegung. Both at the in FIG. 5 illustrated movement with unlocked latch assembly as well as in the FIG. 6 illustrated movement with locked Bar arrangement, the coupling surfaces 114, 122, 214 and 222 are completely dissolved in a Torblattbewegung along an arcuate portion of the predetermined path from each other and get back in the course of the web in a position in which they can be applied by an axial movement back together and a transmission of Allow pushing and pulling forces. The inventive design of the coupling rods therefore a reliable transmission of push and pull movements between the coupling rods 110 and 210 while ensuring a trouble-free Torblattbewegung is possible.

In FIG. 7 For example, there is shown an entrainment device for coupling the coupling rods 110 and 210 to a latch assembly. The entrainment device has a driver element 310 penetrated by the coupling rod 110, wherein the coupling rod 110 is accommodated with play in the entrainment element 310. The driver element can be applied to an actuator 50 of serving as an actuating and locking device lock 14.

The entrainment element 310 has two spaced-apart in the direction of the pivot axis and interconnected via a connecting leg in a direction perpendicular to the pivot axis cutting plane approximately U-shaped running receiving leg 314, between which in a direction perpendicular to the pivot axis extending plane also approximately U-shaped Transmission element 320 is added. The transmission element 320 is, as particularly apparent in FIG. 7d can be seen, also penetrated by the coupling rod 110. The coupling rod is clamped to the transmission device via a clamping screw screwed into a threaded bore 322 of the transmission element 320. Due to the two-part design of the driving device with the driving element 310 and the transmission element 320, the compensation of misalignment in the vertical alignment of the push rod is possible, while at the same time ensuring the transmission of push and pull movements of the coupling rod 110 to the actuator 15 and the actuator 15th on the coupling rod 310 a floating in a direction perpendicular to the longitudinal direction of the coupling rod 110 extending plane of the Koppenkstange 110 using the recorded between the areas 314 connecting device 320 is made possible.

The movement of the driving device 300 with respect to the lock 14 is guided via a guide device. The guide means comprises on the driver element 310 and the transmission element 320 provided guide projections 316 and 326, which are guided in a parallel to the coupling rod 110 extending guide slot 352, which serves in a for fixing the locking device formed by the lock 14 on the door leaf element guide plate 350 is formed. By cooperation of the guide projections 316 and 326 with the guide slot 352, the axial movement or lifting movement of the driver device and thus also the coupling rod 110 is guided and axially limited.

In the FIG. 8 illustrated embodiment of the invention differs essentially by the basis of the FIGS. 2 to 6 illustrated embodiment of the invention in that extending perpendicularly to the plane defined by the tilt axes and pivot axes extending indentation end portion in the form of a mutually aligned coupling rods 110 and 120 respectively in a plane perpendicular to the plane spanned by the pivot axis and the tilt axis extending direction extending taper pin 220 a is formed, which is received in the complementarily executed indentation or bore in the end piece 112 a of the coupling rod 110 a. As from a comparative view of FIGS. 8a to 8c As can be seen, the taper pin 220a can be swung out when passing through an arcuate portion of the predetermined path in the course of an opening or closing movement of the door leaf from the not visible in the drawing indentation or bore, so as to allow trouble-free movement. The taper pin 220a forms coupling surfaces, which, in cooperation with the boundary surfaces of the complementary executed by the taper pin 220a bore in the end 112 a transmission of shear and tensile forces from the coupling rod 110 a on the coupling rod 220 a.

In the FIG. 9 illustrated embodiment of the invention differs essentially by the basis of the FIGS. 2 to 6 illustrated embodiment of the invention, that the coupling rods 110b and 210 b are arranged outside the cover profiles 12 and 22, respectively, wherein the guide of the movement of the coupling rods 110 b and 210 b in a direction parallel to the pivot axis extending direction by means of the coupling rods 110 b and 210b passing through guide slots 116b and 216b is effected, in which the coupling rods 110 b and 210 b with the cover profiles 12 and 14 connecting screws 16 b are recessed. In this case, the screws 16b are accommodated with clearance in the slots 116b and 216b, respectively, so as to enable a smoothly guided pushing or pulling movement of the coupling rods 110b and 210b in a direction parallel to the pivot axis. The coupling rods 110b and 210b, like the coupling rods 110 and 210 of the first embodiment of the invention, are provided with end pieces 112b and 212b, which are interlocked when the coupling rods 110b and 210b are aligned so as to be able to transmit pushing and pushing forces.

The invention is not limited to the embodiments explained with reference to the drawing. Rather, the use of locking arrangements is also intended, in which the locking device is received for securing the escape door in the door leaf elements adjacent Torblattelementen. Furthermore, the coupling rods may also be biased with suitable biasing means in the direction of the locking position of the latch assembly. Of course, bar arrangements according to the invention can also be attached to door leaf elements, which are formed in one piece, without Isolierstoffkern or in the form of aluminum hollow profiles or wood profiles.
