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, slidable in the direction of the pivot axis with respect to the door leaf elements and with respect to the tilt axis against each other tilted Having coupling rods, wherein facing axial ends of at least two coupling rods are connected to each other via a deformable connecting element, as well as a sectional door equipped with such a locking arrangement.

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 section, an approximately rectilinear and approximately parallel to the side Torblattrand in the open position extending horizontal portion and one of 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 allow an opening movement of the door leaf with the therein integrated door leaf is also the door leaf of such constructions of a plurality of co-linear with respect to the tilt axes extending axes against each other tiltable door leaf elements.

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 Torblattelements.

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 an 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 described improvement of the known locking arrangements according to the preamble of patent claim 1 achieved. 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 first the coupling rods must be attached to the individual door leaf elements and coupled to the corresponding locking devices, which then causes a tilting of the door leaf elements with respect to the tilt axes enabling connection between the coupling rods is to produce.

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 to receive 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 fitted edge of the door leaf element and then inserted a locking device and / or an actuating device in a recess of the cover 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 Sektionaltorblatt wicket doors is reached, it has been shown that still a considerable amount of time is required for this assembly, with the reliability of this known latch assembly can not always be guaranteed.

To remedy these shortcomings is in the DE 10 2011 008 224 A1 proposed a locking arrangement for a built-in a door leaf of a sectional door wicket in which the mutually 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. The coupling rods are not permanently connected to each other in this solution, but can be completely detached from each other in the course of a Torblattbewegung along an arcuate portion of a given path. The door leaf elements with the coupling rods held thereon can be connected to each other in this known locking arrangement as a pre-assembled assembly on site for the production of integrated door leafs in a door without the need for a connection between the individual coupling rods must be made. It is no longer necessary to attach the connecting means of the latch assembly to the finished assembled door leaves. As a result, on-site assembly is significantly simplified because a substantial part of the assembly work in the production of preassembled modules, consisting of door leaf elements, coupling rods and possibly locking devices, factory, ie if necessary by machine, can be performed.

However, this latch assembly can lead to incorrect operation when the actuator of the latch assembly is actuated in already raised door leaf, because the thus triggered movement of the actuator associated coupling rod is not transferred to already canceled contact with the subsequent coupling rod on this. This can lead to the individual locking devices being actuated independently of one another, and a regular operating state in which the locking devices are actuated simultaneously again when the actuating device is actuated can only be restored with difficulty.

In view of the above-described 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 high level of reliability with ease of installation and satisfactory burglary.

This object is achieved by a development of the example. From the EP 1 722 052 B1 known latch assembly, which is characterized essentially in that the mutually facing axial ends of the coupling rods connecting deformable connecting element an elongation of less than 10%, esp. Less than 5%, more preferably less than 1%, at a tensile load of 1 N. having.

This invention is based on the finding that tilting of the door leaf elements equipped with the coupling rods with respect to the tilting axes while ensuring a reliable power transmission does not necessarily require the use of elastic and therefore also regularly stretchable connecting elements, for example in the form of cylindrical tension springs, but also can be ensured by the use of plastically deformable fasteners, which have only a slight extensibility.

When using such plastically deformable fasteners can on the use of bolt arrangements according to EP 1 722 052 B1 necessary means for guiding and positioning are omitted. These means are used in bar arrangements according to EP 1 722 052 B1 with elastic connections between successive coupling rods needed to limit the extensibility of the fasteners and the associated risk to the reliability.

In the context of this invention, it has been recognized that in the absence of elastically deformable connecting elements, a sufficient limitation of the extensibility can be achieved, which according to EP 1 722 052 B1 necessary means for guiding and positioning makes dispensable.

When using inventive connecting elements, which are also referred to below as plastically deformable connecting elements, it must be ensured that the deformability of the connecting elements is sufficient to allow a Torblattbewegung along a curved guide rail section. In this context, it has proved to be expedient if the connecting element has an axial length of more than 10 mm, preferably more than 20 mm.

On the other hand, a transmission of shear forces must be ensured with the plastically deformable connecting elements used according to the invention. Therefore, connecting elements according to the invention have an axial length, i. H. a length in the direction of the coupling rods in the closed position of the door leaf, of preferably less than 200 mm, esp. Less than 100 mm, on.

With regard to the necessary deformability according to the invention used plastic connecting elements, it has proved to be expedient if the connecting element is substantially kreiszylindermantelförmig with a diameter of 20 mm or less, preferably 10 mm or less, esp. 7 mm or less executed.

With a view to the necessary transmission of shear forces, the plastically deformable connecting element used according to the invention expediently has a diameter of 4 mm or more, preferably 5 mm or more.

A reasonable compromise between sufficient deformability on the one hand and a reliable transmission of shear forces on the other hand can be achieved if the ratio of the axial length of the connecting element to the diameter in a direction perpendicular to the longitudinal axis cutting plane 20 or less, esp. 15 or less, more preferably 10 or less , is.

In a particularly preferred embodiment of the invention, the connecting element may comprise a wire rope section. In particular, when using such a wire rope section as a connecting element, the axial ends of the connecting element can be pressed into formed in mutually facing axial ends or end faces of the coupling rods recesses.

In the context of the invention, the coupling of the coupling rod to the locking device can take place, for example, in that the coupling rod passes through a locking device and the pushing movement of the coupling rod is suitably transmitted to the locking element by a transmission device arranged in the locking device. However, manufacturing technology and assembly technology, it has proven to be particularly advantageous if at least one coupling rod widening the coupling rod in the radial direction, preferably outside of the non-rotating guide Coupling rod designed guide means arranged and movable in the axial direction with the coupling rod driver means for coupling the coupling rod is assigned to the locking device. 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. Appropriate management and entrainment facilities are in the DE 10 2011 008 224 A1 described. The disclosure of this document with regard to the execution of guide and entrainment devices for coupling the coupling rod to the locking device is hereby incorporated by explicit reference in this description.

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, a door leaf integrated in the door leaf, a guide rail arrangement designed to guide the door leaf movement between an open position and a closed position with an arcuate area between two rectilinear areas and a latch arrangement according to the invention ,

The locking arrangement according to the invention comprises as essential elements two, three or more in each case via plastically deformable connecting elements, esp. In the form of wire rope sections, interconnected coupling rods. These interconnected coupling rods can be preassembled. During assembly of the sectional door leaf, this preassembled module can be inserted into corresponding guide grooves in the pivot axis facing away from edges of the door leaf elements and then coupled to the locking devices. The coupling rods accommodated in the guide grooves can then be at least partially covered by covering devices.

The invention will be explained with reference to the drawing, to which reference is expressly made with respect to all essential to the invention and in the description unspecified highlighted details. In the drawing shows:

• Fig. 1 a schematic representation of two equipped with a latch assembly according to the invention door leaf elements of a built-in a Sektionaltorblatt wicket door,
• Fig. 2 the connection of successive coupling rods of a locking arrangement according to the invention and
• Fig. 3 an illustration of a driver device of 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 10, 20 and facing away from the pivot axis of the door leaf are covered by, for example, cover elements 12 or 22 designed as extruded aluminum profiles in order to protect the foam core accommodated between the sheet metal shells and to stabilize the door leaf element 10 , In the cover 12 is a in the foam core of the door leaf member 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 member 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 member 20 foam core.

From a comparative analysis of the Fig. 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. A 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 10, 20 allowing connection device is hereinafter with reference to the Fig. 2 explained.

Thereafter, the connecting device has a the door leaf element 10 associated coupling rod 110, which is designed as a wire rope section connecting element 30 is coupled to a door member 20 associated with the coupling rod 110 (not shown).

The coupling rod 110 is slidably mounted on the door leaf member 10 with respect to the door leaf member 10 in the direction of the pivotal axis of the door panel. For this purpose, the coupling rod 110 is received in a guide channel 16 of the cover 12, as the Fig. 2b can be seen. 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. 2b reached. Similarly, the door leaf member 20 associated coupling rod 110 is slidably received in a rectangular guide channel 16 of the cover 22 in the direction of the pivot axis and fixed with respect to the door leaf member 20. The designed as a wire cable section connecting element 30 is pressed into an end-side recess of the coupling rod 110. Likewise, the end of the wire rope section 30 facing away from the end pressed into the front end of the coupling rod 110 is pressed into a corresponding recess in the coupling rod assigned to the door leaf element 20.

In the embodiment of the invention shown in the drawing, the wire rope section 30 has a diameter of 5.5 mm. The length of the wire rope section 30 is less than 50 mm. Therefore, the ratio of the axial length to the diameter of the guide member is greater than 10. The wire rope section 30 has an elongation of less than 1% at a force of 1,000 N. The wire rope section 30 has a for securing a smooth movement successive door leaf elements 10, 20 along a arcuate portion of a guideway sufficient deformability. Due to the low elongation ensures that tensile forces are reliably transmitted from the actuator to the locking device 24. The described relationship between the length of the wire rope section 30 and the diameter also ensures the reliable transmission of thrust forces from the actuating device to the locking device 24 of a sectional door according to the invention.

In FIG. 3 a carrier device 300 designed for coupling the coupling rods 110 to a latch arrangement is shown. The driver 300 has an entrained by the coupling rod 110 driver element 310, wherein the coupling rod 110 is received with play in the driver element 310. The driver element 310 can be applied to an actuator 50 of the 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 also penetrated by the coupling rod 110. The coupling rod 110 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 driver 300 with the driver 310 and the transmission element 320, the compensation of misalignment in the vertical alignment of the push rod allows, 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 15 on the coupling rod 110 a floating in a direction perpendicular to the longitudinal direction of the coupling rod 110 extending plane of the coupling rod 110 by means of 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 device has on the driver element 310 and the transmission element 320 provided on guide projections 316 and 326, which are guided in a parallel to the coupling rod 110 extending guide slot 352, in a for securing the locking device formed by the lock 14 24 on the door leaf element 20th serving 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 300 and thus also the coupling rod 110 is guided and axially limited.

The invention is not limited to the embodiment explained with reference to the drawing. Rather, it is also possible to use coupling rods with a rotationally symmetrical cross section. Also is the use of other types of fasteners thought. Instead of guide and entrainment devices interspersed by coupling rods locking devices can be used.

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.
