Description

The invention relates to a sectional door with a door leaf, which is formed from individual, horizontally extending panels, which are connected to each other by means of rotatable connections in the horizontal axis so that the door leaf can be moved from a closed position to an open position and from the open position to the closed position , Furthermore, a door is integrated in the door leaf, the door leaf has substantially the same structure as the door leaf and at least a stabilizing element is arranged in the region of the door leaf below the door leaf.

With the DE 10 2010 000 252 B4 is a sectional door with a door leaf and an integrated door that can be opened in the closed position of the sectional door, has become known. In this case, the door leaf and the door consist of a multiplicity of individual interconnected, mobile sections of panels, the edge of the lowest panel directed to the floor of the building being equipped with a firing profile. This end profile is equipped with a replaceable seal.

In the US 2,718,677 For example, a threshold element for a door is described which has fillets at the edges, the dimensions of which are only a fraction of an inch, so that the total height of the threshold element is less than 25 mm.

The DE 20 2008 000 919 U1 discloses a locking system for a, a fixed wing and a moving wing having double-leaf door, which has at least one designed as escape door closure ball-and-socket closure, which has one or more locking bars, which engage in the course of locking in corresponding locking receptacles and at least one actuating element for unlocking and opening the poppet closure exhibit. Further, at least one trained as emergency exit door leaf closure, which is designed as a drive rod lock with multiple locking and at least one central lock and one or more actuatable via one or more drive rods additional locks, available. The central lock and the additional latches have locking elements which engage in the course of the locking in corresponding locking receptacles in the inactive leaf and interact with at least one actuating element for unlocking or opening the active leaf closure.

With the EP 1 722 052 B1 a lock for an entrance door in a sectional door, especially for garages, has become known. In this case, a device is used for transmitting a lock on upper and lower bars of the lock, which is installed within the sectional door or the like. Between the individual gate elements, above and below, there is a connection of a rod formation which acts as an elastic connection. In this case, the connection comprises means for guiding and positioning, so that the various elements of the integrated door and the door can get into a vertical and horizontal position and vice versa without obstruction of movement and positioning. It does not matter if the door is open or locked. Such training is associated with high costs.

Panic shutters or anti-panic closures usually have a horizontally extending over the entire width of the door inner side bar handle. These devices, which are pivotally mounted on the door leaf and coupled to the door lock at the same time, have the advantage that transmitted by an operation, ie by depressing the bar handle or by a force applied to the pushbar, by means of a transmission, this movement to the castle becomes. When it comes to escape routes, it must be ensured that such a door can be quickly opened from the inside in an emergency. This particular in view of the fact that in case of panic a large number of people flow to such an escape door. It is therefore necessary that such a panic lock can be quickly brought out of a locking position. Therefore, for example, in the bar handles, these are often formed at an angle of 30 ° to 45 ° relative to the plane of the door leaf. This allows by the projecting part, which is realized via lever arms, that a depression of the bar handle in the direction of the door leaf is easy to implement. In this case, the rotational movement of the lever arms of the rod handle via a functional element which has a linkage on the lock side and thus simultaneously by the rotational movement of an opening movement of the castle, ie a retraction of drive rods or the like and at the same time a latch and / or a bolt allows.

In addition to the common bar handles and facilities that are referred to as pushbar, in use. These have proven to be very useful.

The object of the invention is to further develop a door which is located within a door leaf of a sectional door in a number of respects. It is necessary in a first task that such doors are not only usable for passenger traffic, but it should also be possible, if necessary, without opening the sectional door to create a larger passage. Furthermore, the object is that such a door within the door leaf also meets the requirements of an escape door.

The object of the invention is achieved by the teaching of claims 1 and 2. The subclaims have a further embodiment of the inventive concept to the content.

Especially in times of energy-saving measures, it is of great interest in large sectional doors, the opening widths are getting bigger, to have the ability to provide an integrated passage that allows, for example, wider objects and small vehicles in the form of pallet trucks or the like still be able to spend through a passage with the sectional door closed. This meets the invention in a first preferred embodiment, characterized in that the door within the door leaf as a double-leaf, comprising a so-called active leaf and a cooperating passive leaf exists. The active leaf gets its name from the fact that it is used for normal public transport or even for the transportation of smaller portable cars in daily use. In contrast, the inactive leaf is only opened when a larger opening width is required within the door leaf. The larger opening width is achieved by the total achieved by the active leaf and the passive leaf in its horizontal extension expansion. Because the passage within the door leaf is virtually widened by the combination of aisle and inactive leaf, it is necessary for a closing element bridging the door region to be present in the floor area, ie on the lower door panel. At the same time, a blocking unit or lock is provided in the two-leaf door, which allows locking the passive leaf in the closed state. This can be performed, for example, via a drive rod arrangement or the like such that in the locked state, an arrangement within the fold on the bottom side and top side in a stationary frame or a frame construction engages. The blocking or locking unit can also be hidden or arranged on the door leaf.

A suitable lower end element can be realized in many different ways, while at the same time performing a stabilization function for the area of the double-leaf door within the door leaf. So it is desirable that even with smaller vehicles this area of the open standing and active wing can be passed. This is achieved in that no stumbling edges are present and the formation of the closing element is designed according to existing regulations. This can be achieved by providing chamfers or the like, in particular in the lateral edge regions of the closing element, which do not form stumbling edges at their outer edges.

At the same time, such a closure element is equipped with at least one sealing element directed to the ground. In a preferred embodiment, such a closure element may extend over the entire door leaf width.

Due to the fact that the inactive leaf does not have to be opened every time an opening is opened, a lock device in conjunction with a door handle is only present on the moving leaf for opening and closing. Both the trap contained in the lock and the latch engage in a closing mechanism of the inactive leaf.

An inactive leaf, like the active leaf, is preferably provided with a frame profile or the like which adapts to the individual panels hinged to each other horizontally. By such a measure, the appearance of the entire sectional door is standardized to the outside and at the same time, however, it is possible to spend such a sectional door with the two-leaf door education from the closed position to a parking position and vice versa. Such a change of sectional door can be carried out manually or automatically.

Both the active leaf and the fixed leaf are preferably equipped with electrical and / or mechanical safety devices that ensure intrinsically safe operation of such a sectional door. For example, the sectional door can only be moved out of the closed position if there is a proper locking position of the aisle and also the passive leaf.

In order to ensure a daily use of the double-leaf door, it is necessary that there is always a proper closed position between the aisle and passive leaf. This means that due to the folded door leaves first the inactive leaf must take its closed position and then the active leaf. This is achieved for example by a closing sequence control mechanical or hydraulic or electrical type. Such a closing sequence control only works if in addition to the active leaf and the inactive leaf is opened. With an existing closing sequence control, it is possible to open and close the active leaf without impairment, without the closing sequence control is effective. Only at the moment when the passive leaf is opened, the active leaf is prevented from taking its closed position. Only when the inactive leaf has reached its closed position, it is possible that the active leaf also assumes its closed position following it. Such a closure sequence control in an automated area can be realized for example by door closers or drives or electrical locking means.

It is possible that, depending on the design of the door closing device, these are completely concealed or partially concealed within the wall thickness of the door elements, or the panels located above it, are installed. The same applies to the closing sequence control, which can be concealed above the door in the panel can be accommodated.

Since the areas of the double-leaf door are made in the same manner as the formation of the door leaf, it is necessary that in the region of the door leaves, which are framed by frame profiles to perform a vertical axis rotational movements. In order to be able to carry out corresponding cost reductions here, according to the invention it has been possible, in a first preferred embodiment, to form the existing swivel connection between horizontally extending, locally variable elements with an additional swivel connection, which at the same time also has a separate swivel connection for components of the blocking unit. This additional pivot connection is characterized by a separate rotatable connection which allows to receive fasteners. These connecting elements provide the interface to the adjacent pivot joints in the way that between two pivot joints always a transmission element is arranged. Such a transmission element is preferably formed as a flat component. In a preferred embodiment, this transmission element may be made of a spring steel or other suitable material.

In a further preferred embodiment, it is possible that the pivot connection not only includes a separate rotatable connection, but has two rotatable connections, which are interconnected by a center piece.

A normal embodiment of known pivot joints between two horizontally adjustable spatially panel elements consists essentially of two fastening tabs which are rotatably connected to each other by a hinge. Such fastening tabs are fastened to the abutting, movable, horizontally extending panels by screwing. However, to integrate a blocking unit, guide members are preferably included in the mounting tab. Within the guide elements are connected via rotatable connections with each other with the center piece, connecting elements out. A preferred embodiment of the guide can be carried out in guide shots. This ensures that it can not come to a hooking or the like of the center piece with the connecting elements during a pivoting movement of the movable panels.

This preferred embodiment of the use of the center piece and the adjoining connecting elements with the inclusion of rotatable connections offer particular advantages. Thus, for example, in an intermediate position under all circumstances, a rotational movement of the portable panels can be performed by the second pivot joint. In order to be able to have a secure outer termination, the pivot connection in the fastening flap areas is in each case crowned by a cover. Such a hinge connection can also be used without the connecting elements.

In order to be able to carry out a simple assembly of the swivel connection in the region of the locking position, the swivel connection is not set directly on the portable door element, but it is used in conjunction with a closure or frame profile, preferably in folded door leaves. In this case, a transmission element is guided within a profile such that it can be moved in a location. This transmission element has end drivers, which engage in the connecting elements of the second integrated rotary joint connection. As a result, an assembly is greatly simplified, because the placement on the driver is no problem and thus easy to attach the first hinge joint on the end profile or the like with the panel.

This embodiment makes it clear that such a procedure results in a concealed arrangement of the swivel element and the second swivel joint. At the same time, this also offers protection against manipulation, since it is not apparent from the outside that the transmission elements for a translatory movement of a locking or blocking unit are also located within the terminating profiles at the same time.

With such a closure profile, further integrations of the profile can be accompanied at the same time, for example that a side leg is present, which merges into a closing leg and thus securely allows a positioning of the movable panels between them. In addition, it is possible that corresponding sealing means can also be used within such an abutment leg in order to seal a door formation in a sealed manner.

As the preceding description makes it clear, in a further preferred embodiment, the double-leaf door can also be designed as an escape door, with a gangway and a passive wing acting therewith. The opening direction is directed outwards. By a suitable opening mechanism, which is present on at least one of the inner sides of the standing or active leaf, a release of the blocking unit by actuation of a Öffnungsmechanismusses is possible. This is also executable in conjunction with a self-locking panic lock. At the same time it is understood that such a double-leaf door, regardless of escape door or normal double-leaf door, may also be formed with an alarm or other sensors. At the same time an automatic blocking of the door leaf movement is effected upon actuation of the opening mechanism. It is understood that such doors can also be formed with transparent elements, such as windows. Such an opening mechanism is located on the inside of the door or the door. Pressurizing triggers the mechanism.

Depending on the application, it is thus possible to adjust the passage width of the two-leaf door within the door leaf. This means that in addition to a first embodiment, in which the inactive leaf and the active leaf are the same width, different size configurations are possible here. In particular, in the variant of the escape route design, it is possible that the active leaf is greater in width than the fixed leaf.

Further advantages, features and possible applications of the present invention will become apparent from the following description in conjunction with the embodiments illustrated in the drawings.

By the representation according to Fig. 1 a basic arrangement of a door leaf 1 is shown. In this case, the door leaf 1 consists of individual panel elements 5, which are connected in a horizontal manner by rotatable connections 6 with each other so that they can be moved from a vertical closed position into a substantially horizontal opening position. It is irrelevant whether the method of the door leaf 1 of a sectional door or the like is carried out manually or by a motor drive unit. Within the door leaf 1, a double-leaf door 2 is included, which includes a moving leaf 3 and a stationary leaf 4. Laterally, the two-leaf door 2 by a mounting frame 7, which consists of profiles or the like, edged. In this case, the mounting frame 7 is non-positively and positively connected to the respective panel elements 5. Within the mounting frame 7, a sash frame 8 and a sash frame 9 are shown with the an infill of active leaf panels 11 and panel panels 12 represent the two-leaf door 2.

In order that the active leaf panel 11 and the fixed leaf panel 12 can be moved in the same manner as the panel elements 5 about horizontal pivot axes, these have rotatable connections 14. In order to be able to effect an opening of the active leaf 3 and also of the passive leaf 4, it is necessary for these to be connected to the mounting frame 7 by hinge connection 15. Depending on the design of the hinge connection 15, it is possible that the active leaf 3 and the stationary leaf 4 can be opened either to the building interior, in an escape route version, the opening but directed outwards. The closed position of the two-leaf door 2 is ensured by a lock 10, which can also be aligned as a self-locking panic lock.

The infills, both of the inactive leaf 4 and of the active leaf 3, can be filled by the same panel elements 5, but it is also possible to provide corresponding other elements here, e.g. a glazing or the like.

At least the area between the inactive leaf 4 and the moving leaf 3 is bridged by a bottom-side closing element 13. This bridging provides the necessary stabilization, so that the door leaf 1, even when the door leaves 3, 4 open no distortions. Such a closure element 13 can also be performed over the entire width of the door leaf 1. At the same time it acts as a threshold as well as a stabilizing element.

These frame formations 8 and 9 are not to be understood as continuous one-piece frames, but form only the lateral terminations to the individual panels 5. In the region in which the active leaf 3 and the inactive leaf 4 meet, the stationary leaf 4 preferably has hinge connections 30, which take on an additional function.

The configuration of the end element 13 can be carried out in various embodiments. In a first preferred embodiment according to Fig. 2 the end element 13 has been shown as a flat component. Such a closure element 13 is designed so that it complies with the valid building codes. In each case, on the sides of a run-on slope 24 is present, which merges into a rounded front edge 25. Subsequent thereto, a footprint 26 is present on the underside, directly or indirectly with the building floor in Contact is coming. The upper area forms a tread surface 16, which is formed as a continuous, substantially straight surface, and may be equipped with a corrugation or the like to increase the slip resistance. Can be interrupted, the tread surface 16 by grooves 18, can be connected via the other components of the door leaf 1 with the closing element 13. Overall, the connection of the closing element 13 via screw inlets 17, which are arranged on the underside of the closing element 13, can be produced with screw connections to the lowermost panel element 5.

Within the closing element 13, an inlet 23 is preferably present, which widens further in lateral undercuts 21. Depending on the requirements, seals or supply and sensor cables can be laid here. In a further inlet 22, it is also possible to accommodate a seal or else in a subsequent receiving channel 20 cable. By an undercut 19 within the inlet 22, an introduction of the seal is also possible.

In a modified embodiment according to Fig. 3 it is possible to remove a further closing element 13. This terminating element 13 is similar in construction to the embodiment according to FIG Fig. 2 to see, however, has been waived in the area of the abutting edges 25 on chamfers or the like. By pulled out lower protruding tread bar 49 a larger space is created below the end element 13. This larger space makes it possible, for example, to introduce larger sealing elements for large opening widths.

As the design of the two final elements 13, which are not exhaustively described, shows, they have been designed in such a way that, in the sense of official regulations, there are no stumbling edges in the region of the double-leaf door 2.

In the Fig. 4 a section of a door leaf 3 or 4 is shown, in which on the left side two panel elements 5 have been shown one above the other. The left connection between the panel elements 5 has not been shown. On the right side, following a vertical edge of the stacked panel elements 5, a frame profile 27 has been shown. This frame profile 27 consists of several segments which have the same height as the panels 5 and are interconnected by a hinge joint 30. The frame profile 27 has for the front edge of the panel element 5 a side leg 29 and a thereto projecting plant leg 28 on. By the plant leg 28 a secure conclusion is made to the adjacent door element.

By the representation of the Fig. 5 the functional design of the frame profile 27 in connection with the pivot connection 30 becomes clear in many respects. While the plant limb 28 also provides a seal receptacle 31 for sealing the door leaf 2 with each other, a further projecting part in the form of a terminating limb 32 has subsequently been shown on the opposite side. This end leg 32 lays on the surface of the panel elements 5. This can also be done by the Fig. 6 be clarified, which represents a rear view in a slightly pivoted position of the frame profile 27 in conjunction with the pivot joint 30 and a transmission element 37. Thus, the transmission elements 37 are translationally changeable in a leg of the frame profile 27 in guides 33. The transmission elements 37 are connected by connections 36 to the second rotary connection within the pivot connection 30. The transmission element 37 is accessible through a free space 35.

In particular from the representation of Fig. 6 It is clear that in addition to the pure pivotability of the panel elements 5, a pivotability of elements for a locking device in the form of the transmission elements 37 is given. At the same time within the swivel joint 30, the transmission element 37 is guided so that in the closed position of the inactive leaf 4 at least one blockage is possible. The transmission elements 37 are equipped at the end with correspondingly suitable closure pieces, which engage on the one hand in the end element 13 and on the other hand engage in the upper frame in the mounting frame 7 or parts of the mounting frame.

So according to Fig. 7 the functionality and necessary for the pivotal connection elements, and necessary for the locking elements are taken in the form of transmission elements 37 in a cooperation as a hinge joint 30. The hinge joint 30 consists essentially of mounting plates 44 and 45 which are pivotally connected to each other via a hinge 38. The fastening plates 44, 45 are screwed onto the panel elements 5 or the frame profile 27. Within the mounting plates 44, 45, a mechanism is included, which in addition to a pure rotational movement about the joint 38 and independently of this allows a change in location of the integrated transmission elements 37 in the translational direction. For this are located on the transmission elements 37 end driver 43, the in Intervene fasteners 46. This intervention is realized in a simple manner by a plug connection. The transmission elements 37 are guided within lateral guides 33 which are contained in the frame profile 27. Following the guides 33, a free space 35 is present, which includes a cutout 34. Thus, it is possible that the transmission element 37 can be moved here concealed within the frame profile 27 translationally by actions of the lock 10. In a preferred embodiment, a connecting center piece 47 is present on the connecting elements 46 at the end. This center piece 47 is connected via rotatable connections 48 with the connecting elements 46. With this configuration, it is possible that even with not 100% correct matches of the rotatable connection 48 with the hinge 38, the functionality of the transmission elements 37 is maintained. This position can be particularly the Fig. 6 can be taken, from which it is also clear that due to the center piece 47, regardless of the joint 38, a rotational movement about the rotatable connection 48 is possible. To avoid manipulation, the mounting plates 44, 45 are crowned by covers 40, 41. Thus, in addition to a secure conclusion and a visually good appearance is given.

Instead of a door handle to be used usually in doors, it is possible in an embodiment of the two-leaf door 2 as escape route doors to provide them with an escape route door fitting, which is arranged on the inside of the door surfaces. Such a door fitting, which can be referred to as a door mechanism, acts directly or indirectly on the blocking unit, which ensures locking of the two-leaf door 2 in the closed position between the closing element 13 and the mounting frame 7 or the like. For this purpose, there are a variety of execution options, wherein in addition to the safety function also preferably a design with not very far projecting elements is given preference. Upon actuation of these opening mechanisms, which may be mounted both on the moving leaf 3 and on the inactive leaf 4, in addition to an actuation of the lock 10, a geared transmission is simultaneously exerted on the translationally movable transmission elements 37. By means of this geared connection, it is ensured that, in all cases, when force is applied to the inside of the active leaf 3 and / or the inactive leaf 4, a forced opening of the double-leafed door 2 is carried out. As a result, it is possible for persons to come out of a building in the event of danger, in which case the tripping-free design of the closing element 13 does not affect the escape and rescue route.
