Description

FIELD OF THE INVENTION

The present invention relates to a closure device for building openings or rooms, a tape for connecting a closure device with double-sided locking to a frame, a mullion for a double-leaf closure device, and an assembly method for assembling a mullion.

TECHNICAL BACKGROUND

Safety doors or safety flaps are used for different applications and serve in particular to protect a separable area from physical influences such as pressure, temperature, water and/or steam.

Security doors are flat locking devices that are preferably held in a frame (or frame) and can be fixed in a closed position in this. The safety doors can be designed in particular as fire protection doors, smoke protection doors, pressure doors or the like and form a pressure-, temperature-, water- and/or smoke-tight connection with the frame, so that an area separated by the safety door can be protected from physical influences. The separable area can be a building or part of a building or, for example, a single room. Security doors can be designed with one or two leaves and are used, for example, in stairwells, for technical rooms or for commercial premises.

Safety flaps are flat closure devices that are designed, for example, to separate a shaft or the like. These can be used, for example, as fire dampers, smoke dampers or pressure dampers.

In order to give the locking devices sufficient stability against the physical effects, different layers of fire protection material are usually used, which are arranged in a supporting shell and form the majority of the flat element and thus the door leaf.

That's it DE 196 25 643 C2 a security door is known which has a peripheral tubular frame. The tubular frame is surrounded by a material that generates a cooling flow when exposed to heat. Shell elements are arranged on two sides of the tubular frame to form the door leaf. A refractory material is provided between the shell members. The boltwork is arranged outside of the shell elements and is fastened to the outside of one shell element by means of a profile. An area on the side of the profile is filled with insulating material to achieve an even surface.

The disadvantage of known locking devices is that they are very heavy due to the multi-layer structure and are designed with a comparatively large cross-sectional depth compared to conventional doors. The use of steel plates as a supporting shell creates disadvantageous thermal bridges through the locking device.

In order to increase the tightness of the closure devices, seals are proposed in various areas.

This is how it shows EP 2 633 145 B1 a fire protection door, which is made up of different insulating layers and fire protection panels with a metallic support structure and has several swelling seals on the frame between the door leaf and door frame. A gap between the door leaf and door frame is closed by the swelling seals, so that the tightness of the fire protection door can be improved.

Disadvantageously, a locking element for locking the door runs through all the insulating layers and also makes contact with the metallic support structure inside the door leaf. This creates thermal bridges that connect the area to be separated on one side of the door with the area where the heat is generated. The seals in the area of the frame can therefore not prevent thermal bridges in the area of the locking element.

Closing devices can also be designed as a pressure door or pressure flap. With such designs, there is still the problem that opening the closure device can be made more difficult by the pressure applied on only one side, since the closure device must be moved counter to the direction of the pressure forces when opening.

If closure devices are double-winged, the above-mentioned problems with regard to geometric dimensions, tightness and thermal bridges also exist for an inserted middle post, which serves to connect both wings of the closure device.

SUMMARY OF THE INVENTION

Against this background, the object of the present invention is to provide an improved closure device and an improved Seal in the area of the frame as well as in the case of double-leaf locking devices in the area of a mullion.

According to the invention, this object is achieved by a closure device having the features of patent claim 1, by a strap having the features of patent claim 17, by a mullion having the features of patent claim 18 and/or by an assembly method having the features of patent claim 25.

Accordingly, it is provided:

A closure device for building openings or rooms, in particular a single or double-leaf safety flap or safety door for pressure protection, with a peripheral tubular frame that forms an enclosed area within a first plane, with a first plate-shaped element that contacts the tubular frame on a first side and the enclosed Area bounded in a direction orthogonal to said first plane, and locking means disposed within said enclosed and bounded area and locking through at least one recess (2b) provided in said tubular frame.

A hinge, in particular a door hinge, for connecting a locking device with double-sided locking to a frame, having a first hinge (22a) which has a first tab coupled to the locking device, and a second hinge which has a second tab coupled to the frame , and a link coupled to the first and the second hinge, wherein a first axis of rotation of the first hinge is arranged offset laterally to a second axis of rotation of the second hinge, so that in a closed position the locking device can be pressed against the frame without rotation by locking on both sides and a gap between the locking device and the frame can be sealed airtight with even pressure.

A mullion for a double-leaf closure device, with a profile element for forming a stop for the closure device, which has an inclined contact surface, with a fixing device, which has an adjustable mounting device for the profile element, and with an installation element, which has an inclined installation surface corresponding to the contact surface has, wherein a seal is arranged between the contact area and the installation area, on which a contact pressure can be applied via the contact area and can be supported against the installation area by adjusting the mounting device.

An assembly method for assembling a mullion, comprising at least the steps of: anchoring the positioning element in a floor; Arranging the profile element so that the sloping contact surface of the profile element contacts the corresponding sloping installation surface of the installation element, with the seal being arranged on the contact surface, in a depression in the contact surface and/or in a depression in the installation surface before the profile element is arranged; Fixing the profile element with the fixing device and generating a contact pressure force of the contact area against the seal and against the installation area by means of the adjustable assembly device.

The finding/idea on which the present invention is based is that, by forming a filling-free cavity for accommodating the locking device, installation space can be saved on the one hand and a high degree of multifunctionality of a door structure can be achieved on the other.

Furthermore, the use of seals can result in a thermal separation, in particular between the support shell and the locking device, which results in a reduction in the thermal bridges between the two sides of the locking device.

The idea on which the present invention is based is to integrate the locking mechanism into the supporting shell and to ensure the stability of the locking device by means of a peripheral tubular frame.

With such a locking device, for example, it is possible to implement a one- or two-leaf safety door or flap, which can be designed, for example, as a pressure door, fire protection door and/or smoke protection door. A high level of tightness against water, air and/or smoke can be achieved by the closure device, with high fire protection requirements being able to be met at the same time. Thanks to the all-round tubular frame and the integrated locking device, the locking device can withstand high pressure forces.

Furthermore, it is advantageously possible in this way to form a double-leaf safety door with a central post, with locking devices for fixing the double-leaf safety door being able to engage in the middle post. With seals on the mullion and an appropriate assembly process, a double-leaf locking device meet the above requirements.

The closure device is preferably flat and designed as a door element, a gate element or a flap. A locking device can therefore be understood to mean a door, a flap or a gate, in particular a security door, a security gate or a security flap, preferably a fire protection door, a fire protection flap, a fire protection gate, a pressure door, a pressure gate or a pressure flap.

The closure device can be arranged at a building opening, as a result of which a separable area, for example an individual room or a section of a building, in particular a stairwell or a commercial area, can be protected. A chamber, such as a security or panic room, safe or similar, can also be partitioned off.

The tubular frame can have different configurations, for example it can have a square or rectangular cavity cross-section. An elliptical or triangular cavity cross section is also conceivable.

The tubular frame preferably has a hollow profile with a cavity cross section that is constant at least in sections. The cavity cross section can also have a constant cavity cross section all around. The sections of the tubular frame, which are preferably arranged at right angles to one another and enclose the enclosed area, can be welded or screwed to one another.

In a preferred embodiment, the tubular frame is formed from a box profile, in particular a rectangular one, which in particular has sharp edges rather than rounded ones. Such a sharp-edged profile can be achieved, for example, with a welded profile, in particular a laser-welded profile or a hot-rolled profile. Due to the sharp edges, ie edges with a very small radius, the tubular frame can be in almost full-area contact with the plate-shaped element with an outer surface which forms the first side. Advantageously, the tubular profile can be welded to the plate-shaped element at the sharp edges, whereby ordinary fillet welds can be used through the mutually arranged perpendicular surfaces, namely the outer surfaces of the tubular profile and the plate-shaped element.

The tubular frame and the plate-shaped element are preferably made of steel and can have different thicknesses depending on the static requirements. The first panel-shaped element can be covered, for example, with a fire protection material in the form of a fire protection building board. The fire protection material is preferably arranged on an outside of the closure device, and thus on a surface of the plate-shaped element that is not connected to the tubular frame.

The fire protection material can contain silicate fibers, for example. In particular, the fire protection material can be classified according to DIN EN 13501-1:2010-01 with fire behavior according to class A1. When using protective panels, these can be mineral-bound protective panels that are dimensionally stable, large-format and self-supporting.

The locking device lies within the area enclosed by the tubular frame and is therefore preferably in one plane with the tubular frame. Since the enclosed area is without filler material, the locking device can be arranged at any desired position within the enclosed and limited area and can be designed to take up any space. It is thus possible, for example, for the locking device to form a connection over the entire width or entire height to two opposing sections of the tubular frame within the enclosed area. By means of only one locking device, a so-called double-sided locking can be formed, for example, without increasing the cross-sectional depth of the locking device.

To fix the closure device in a closed position, the locking device engages through at least one recess provided in the tubular frame. In this way, a connection to a frame can be established, which preferably surrounds the closure device. Due to the empty cavity, the locking device can reach any recess arranged on the tubular frame.

The tubular frame preferably forms a type of base frame in which the locking device is integrated. As a result, easier assembly and disassembly can be achieved, since only one component that includes the tubular frame and the locking device has to be replaced.

The locking device can, for example, be supported against the tubular frame and/or be connected to the first plate-shaped element.

The hinge, in particular the door hinge, is in particular articulated and comprises two hinges. This allows the locking device to be pressed against the frame, further increasing water, smoke and airtightness. The tape can be used for a single leaf or double leaf locking device. Due to the band, the locking device is pressed even closer to the frame without rotation after closing by locking, which results in a high pretension of the seal and thus the improved tightness.

Advantageous refinements and developments result from the further dependent claims and from the description with reference to the figures of the drawing.

According to an advantageous embodiment, at least one opening element can be arranged on the plate-shaped element on a side opposite the tubular frame and contact the locking device through the plate-shaped element, so that the closure device can be fixed in a closed position by moving the opening element. Advantageously, by actuating the external opening element, the locking device is displaced in such a way that it protrudes through the recess beyond the tubular frame and can engage in a frame, for example. The locking device can therefore ensure a connection from the enclosed area inside the tubular frame to an area outside the tubular frame. The entire area in which the locking device is located is advantageously covered by the first plate-shaped element. The locking device is therefore arranged completely behind the supporting shell and is not directly exposed to physical influences such as pressure, temperature, water and/or steam. The opening element can be designed as a lever or handwheel. In addition to the opening element, a handle can be arranged on the closure device, which is only used to open or open the closure device and has no influence on the locking device with the opening element.

According to a development, a second panel-shaped element can contact the tubular frame on a second side opposite the first side and delimit the enclosed area in a direction opposite to the orthogonal direction, so that the tubular frame forms a closed cavity for receiving the first panel-shaped element and the second panel-shaped element form the locking device. In this way, the locking device can be arranged in a completely closed cavity between two supporting shells, namely the first and the second plate-shaped element. A fire protection material, in particular a fire protection building board, can be arranged on both plate-shaped elements on a respective surface which forms a surface of the closure device. In this embodiment too, the cavity preferably remains without filling material.

According to one embodiment, the second plate-shaped element for opening the cavity can be attached pivotably to the tubular frame. In this way, an exchange of individual components of the locking device or an exchange of the complete locking device is advantageously possible without removing or replacing the complete closure device.

According to an advantageous embodiment, the tubular frame can have a tubular profile with a cavity cross section, in which a fire protection material is arranged. In this way, thermal bridges between the first and the second plate-shaped element can advantageously be avoided. The fire protection material can contain, for example, a mineral-bound fire protection building board, in particular made of technical calcium silicate.

According to a preferred embodiment, the tubular frame can form an outer edge of the closure device, in particular a fold, at least in sections. In this way, after reaching through the recess in the tubular frame, the locking device can reach a frame directly in order to fix the closure device in a closed position. In this case, the tubular frame can have the largest possible dimensions within the closure device, as a result of which the largest possible cavity or enclosed area is formed.

According to a preferred embodiment, a sealing element that expands due to the action of heat, in particular that foams up, can be arranged on an outside of the tubular frame, which sealing element can be contacted for fire-protection sealing against a frame surrounding the closure device. As a result, increased fire protection requirements can be achieved since the air gap between the outside of the tubular frame, which in particular forms a fold, and the door frame with the frame with the expanding sealing element can be dynamically filled when heat develops. The expanding sealing element can contain a flexible intumescent fire protection laminate. The expanding sealing element can be a glass fabric as the carrier material have and / or contain vermicular graphite, which is bound and solidified in a thermally stable binder.

According to an advantageous embodiment, the first plate-shaped element can protrude parallel to the first plane beyond the tubular frame and form an overhang, on which a sealing element that expands, in particular foams, is arranged as a result of the action of heat, which can be contacted for fire protection sealing against a frame surrounding the closure device. Advantageously, an air gap between the overhang and the frame can be filled dynamically when heat develops, so that in particular behind it, d. H. in the direction of the fold, arranged seals are protected from heat.

According to a development, the fire protection seal can be provided as a multi-part fire protection sealing device, with the expanding sealing element being covered with a non-combustible, non-expanding sealing layer. In this way, when the expanding sealing element foams up, the non-combustible sealing layer is pressed against the frame, in particular the frame, as a result of which fire safety can be further increased. The non-combustible sealing layer may contain a non-combustible fabric seal.

According to one embodiment, a temperature-resistant insulating layer can be arranged between the tubular frame and the first plate-shaped element. A thermal separation between the supporting shell and the tubular frame is advantageously possible in this way. The insulating layer is in particular designed to be resistant to high temperatures, so that a material difference can be produced between the material of the supporting shell with the tubular frame and the insulating layer to form the thermal separation.

In a further advantageous embodiment, the tubular frame can be formed from a rectangular profile, with the first plate-shaped element being fixed by two opposite weld seams, in particular fillet weld seams, on the rectangular profile, with the insulating layer being arranged between the two weld seams. The rectangular profile is advantageously designed as a box profile with sharp edges and can therefore be securely welded to the plate-shaped element using ordinary fillet welds. By using a box profile with sharp edges, the insulating layer in particular can be formed with a constant thickness over the entire length. The only remaining thermal bridges are the weld seams, which in the form of fillet welds have a small contact area with the plate-shaped element and with the tubular frame.

According to an advantageous embodiment, the insulating layer can contain a glass fiber felt. This is advantageously designed to be resistant to high temperatures. The glass fiber felt can be based on calcium-magnesium silicate and/or have a thermal and physical stability of up to 1200° in particular.

According to a further advantageous embodiment, the locking device can have at least one locking element, a toothed rack coupling the locking element, a toothed wheel actuating the toothed rack and an opening element actuating the toothed wheel, so that the locking element can be moved within the recess in the tubular frame by actuating, in particular rotating, the opening element . As a result, the locking device can be designed to take up space within the closed cavity and can reach any desired areas of the tubular frame. In particular, the opening element can be arranged at any position of the closure device. In particular, a one-sided locking can be formed with such an embodiment.

According to a further development, the locking device can comprise at least two locking elements, two toothed racks coupling the respective locking elements and a common gear wheel actuating both toothed racks, so that by actuating, in particular rotating, the opening element, both locking elements can each be moved within a recess in the tubular frame, with the two locking elements in particular reach through the tubular frame in recesses on opposite sides. With such an embodiment, a two-sided locking can be formed. The locking elements can engage opposite sides of the tubular frame at any height and can be actuated by a common opening timing element.

According to a further embodiment, an angle profile can be arranged between each toothed rack and each locking element and bring about a force transmission of the toothed rack from a movement plane associated with the toothed rack to the locking element in a movement plane associated with the locking element. Due to the angle profile, the force can be transmitted from the opening element to any plane within the closed cavity or the enclosed area, whereby in particular the at least one locking ment element can intervene in the tubular frame at any position or level.

According to a further embodiment, at least two locking elements, in particular four to eight locking elements, can be provided, with all locking elements being movable by the opening element and the closure device being able to be fixed in a closed position. This is achieved in particular in that a connecting device connects all the locking elements to the opening element. The connecting device can be designed as a toothed rack, which connects all the gear wheels of the locking device to one another. The opening element can only be in contact with a gear wheel of a locking device in order to bring about a power transmission from one gear wheel to the connecting device and then from the connecting device to all further gear wheels.

In a further embodiment, at least one pressure compensation valve can be arranged in the closure device. The pressure compensation valve preferably has at least one recess which forms a connection from a side that is not pressurized to a side that is pressurized, with the sides being arranged on opposite sides of the planar closure device. A closure element is advantageously included, which is designed to open and close the recess. In a preferred embodiment of the pressure compensation valve, at least one seal can be arranged between the closure element and the recess.

According to an advantageous embodiment of the center post, the positioning element can be designed as a wedge. Advantageously, the wedge is firmly connected to the ground, so that the sloping contact surface of the profile element can be supported against the corresponding sloping installation surface of the installation element.

According to a further advantageous embodiment of the center post, the fixing device can be designed for positioning and fixing the profile element. For this purpose, the adjustable mounting device can have connection means such as screws or bolts, for example, which create a connection between the profile element and the mounting device. The connecting means can engage, for example, in bores in the profile element and in bores in the mounting device. At least some of the bores can be in the form of oblong holes in order to achieve a desired positioning.

According to an advantageous embodiment of the center post, the stop can be arranged on a side opposite the fixing device with respect to the profile element on the center post. Advantageously, the fixing device with the adjustable mounting device does not affect the area of the stop. Therefore, for example, the tightness in the area of the stop is not influenced by the fixing device.

According to a development of the mullion, the seal can end flush with a front side of the profile element and a front side of the positioning element, in particular can be cut off flush with it. Advantageously, as a result, the closure device can be in full-surface contact with the profile element, the seal and the positioning element over the entire length of the stop. The seal is therefore preferably arranged on a front side of the profile element, so that the seal can also be in contact with the closure device when the closure device is arranged in a closed position. As a result, the tightness can be further increased.

According to an advantageous embodiment of the center post, the seal can be arranged at least partially in a depression in the contact area and/or in a depression in the standing surface. In this way, the seal can be positioned and held in a desired position on the sloping contact surface or the sloping installation surface. The position of the seal is therefore not influenced or undesirably changed by fixing and positioning the profile element by the fixing device. Due to the arrangement in a recess, the seal is advantageously not excessively pressed by the contact pressure of the contact area on the mounting surface, so that on the one hand the seal retains its shape and on the other hand the contact area and the installation area can be contacted over the entire surface outside of the recess.

According to a further advantageous embodiment, the seal can be designed as a double seal and/or have a U-shaped cross section. As a result, the sealing properties can be further increased.

According to an advantageous embodiment of the assembly method, the seal can be cut off after the profile element has been fixed, so that the seal is flush with a front side of the profile element. As a result, the seal does not have to be adapted exactly to the dimensions, for example of a recess, during assembly of the profile element with the fixing device be. By cutting off the seal flush, full-surface contact between the closure device and the stop, as already described with regard to the middle post, can be achieved.

The above configurations and developments can be combined with one another as desired, insofar as this makes sense. Further possible configurations, developments and implementations of the invention also include combinations of features of the invention described above or below with regard to the exemplary embodiments that are not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

1 shows an embodiment of a closure device 1 according to the invention as a cross-sectional view. A peripheral tubular frame 2 is arranged in a first plane E1 and forms an enclosed area 3 . A plate-shaped element 4 contacts the tubular frame 2 on a first side, so that the enclosed area 3 is further limited in a direction R1 orthogonal to the first plane E1. Within the enclosed area 3, which is also delimited by the first plate-shaped element 4, a locking device 5 is arranged. The locking device 5 engages in a recess 2 b arranged in the tubular frame 2 . As a result, the locking device 5 can reach a frame 18 and thus fix the closure device 1 in a closed position P1.

In this embodiment, the locking device 5 is designed in two parts, with a horizontal section engaging in the recess 2b and being held centrally in the circumferential tubular frame 2 by a vertical section. The vertical section stands in this embodiment with the first plate-shaped element 4 in contact. The enclosed area 3 is accessible from one side (from above in the illustration), so that, for example, the locking element 5 can be operated or replaced from this side.

In 2 a further embodiment of a closure device 1 can be seen as a cross-sectional representation. In contrast to the embodiment according to 1 a second plate-shaped element 7 is arranged on the tubular frame 2 on a second side opposite the first side.

As a result, the enclosed area 3 is further limited in a direction R2 opposite to the orthogonal direction R1, so that a closed cavity 8 is formed. The locking device 5 is arranged entirely in the closed cavity. The re 1 The vertical section of the locking device 5 described above is designed as an opening element 6 that protrudes through the first plate-shaped element 4 . In this embodiment, the locking device 5 can therefore be operated from another side of the closure device 1 (from the bottom side in the illustration). The opening element 6 is shown only schematically and can be designed, for example, as a lever or hand wheel.

A further embodiment of a closure device 1 is shown as a cross-sectional view 3 . The second plate-shaped element 7 is pivotally attached to the tubular frame 2 so that the cavity 8 can be opened. As a result, for example, the locking device can be replaced or repaired without having to replace the entire closure device 1 .

4 shows a closure device 1 according to the invention as a pressure flap. The peripheral tubular frame 2 and the locking device 5 can be seen in the partially transparent representation. The tubular frame 2 forms part of an outer edge 14 of the closure device 1 and serves as a fold 15. The locking device 5 runs transversely within the enclosed area 3 and is designed in several parts in this embodiment.

The pressure flap off 4 has a one-sided locking with a locking element 9, which extends through the tubular frame 2 in the form of a bolt. The locking element 9 is connected to an angle profile 12 which in turn is in contact with a toothed rack 10 . The toothed rack 10 connects the locking element 9 to a gear wheel 11 which is connected to the opening element 6 . As a result, the force can be transmitted from the opening element 6 to the bolt.

5 shows a cross-sectional representation along the section plane BB 4 . The locking element 9 engages in the frame 18 in order to fix the closure device in the closed position P1. Through the angle profile 12 a power transmission with respect to different levels within the cavity 8 is possible. The angle profile 12 transmits the force from a plane of movement B2 associated with the toothed rack 10 to a plane of movement B1 associated with the locking element 9 . The distance between the two planes of movement B1, B2 can be influenced via the leg length of the angle profile 12. The angle profile 12 is designed in particular as an L-angle with legs arranged at right angles.

In this embodiment, the opening element 6 engages through the first plate-shaped element 4 and through the second plate-shaped element 7. As a result, the closure device 1 can be designed with a lever arranged on each side and can be operated from both sides.

To improve the fire protection properties, the closure device 1 has a fire protection material 13 on the outside of each plate-shaped element 4 , 7 . This can be designed as a fire protection panel. In addition, a fire protection material 13 is arranged in a cavity cross section 2a of the raw profile that forms the tubular frame 2 . As a result, the thermal bridge between the plate-shaped elements 4, 7, which is produced in particular by the tubular frame 2, can be reduced.

6 shows a further cross-sectional representation along the section plane BB 7 . In 7 a closure device 1 according to the invention is shown as a pressure door. In contrast to the embodiment according to 4 the pressure door has three locking devices 5 which are arranged at different heights. All three locking devices 5 can be locked or unlocked by a common opening element 6, such as with respect to 11 and 12 explained in more detail. Unlocking or locking takes place via an opening element 6, which is shown in the closed position (horizontal position) and in the open position 6'. A handle 30 is additionally arranged for opening the pressure door itself. This is independent of the locking device 5 and the opening element 6. In the sectional view in FIG 6 it can be seen that the locking device 5 has a further connecting element 9a which connects the locking element 9 to the angle profile 12 . A distance within the cavity 8 that is present between the locking element 9 and the angle profile 12 can be bridged by the connecting element 9a.

The closure device 1 according to 7 also has a pressure compensation valve 200 . This will re 14 explained in more detail.

A further cross section through a closure device is shown 8th . In contrast to the representation from 6 the closure device 1 shown has a double-sided locking mechanism. This can be seen from the fact that a further rack 10, a further angle profile 12 and a further connecting element 9a are shown on the left-hand side of the illustration. These are also actuated via the gear wheel 11. In order to achieve improved water, smoke and airtightness, the closure device 1 has a band 100 that forms a connection between the closure device 1 and the frame 18 . If the locking device 1 is designed as a security door, the hinge 100 is a door hinge 100a. The band 100 serves to push the closure device 1 further towards the frame 18 after it has been closed and until it is locked.

9 10 shows two embodiments of a band 100', particularly from the prior art. These each have only one hinge 22'. The hinge 22' is connected to the closure device 1 by a first tab 29a and to the frame 18 by a second tab 29b. After closing and until the locking device 1 is locked, the locking device 1 cannot be pressed any further, since there is only one axis of rotation r1.

An embodiment of a band 100 is in 10 shown. This has two hinges 22a, 22b. The first hinge 22a is connected to the closure device 1 by a first tab 29a. The second hinge 22b is coupled to the frame 18 with a second tab 29b. The two hinges 22a, 22b are coupled via a link 27. This represents a connection between the two axes of rotation r1, r2. The two rotational axes r1, r2, which are laterally offset from one another and are coupled, can be used to allow the closure device 1 to be pressed against the frame 18 without rotating, by locking on both sides in a closed position B1. As a result, the closure device 1 is pressed further against the frame 18 between the closing and the locking of the closure device 1 .

11 shows an embodiment of the closure device 1 with locking on both sides. The locking device 5 has a total of eight locking elements 9 which are arranged on two opposite sides on the tubular frame 2 and protrude from the tubular frame 2 in order to fix the closure device 1 in place. The eight locking elements 9 can be actuated via a common opening element 6 . In this embodiment, this is designed as a handwheel.

In 12 is a longitudinal section through the version shown in 11 shown. Two locking elements 9 each are coupled to a common gear wheel 11 . The resulting total of four gears 11 are coupled to one another via a vertically arranged connecting element in the form of a toothed rack 10'. Another gear wheel 11 ′, which represents a connection to the opening element 6 , is connected to a gear wheel 11 . As a result, by actuating the opening element 6, a force can be transmitted via the gear wheel 11' to the gear wheel 11 (the second gear wheel from the top in the illustration). The force is transmitted to all gear wheels 11 and thus to all locking elements 9 via the connecting element in the form of the vertically arranged toothed rack 10'.

Another possible cross-section through the design according to 12 indicates 13 . In this embodiment, a further closed cavity 8' is arranged next to the closed cavity 8, through which, for example, the fire protection properties of the closure device 1 can be further increased.

14 shows a locking device 1 according to the invention with a pressure compensation valve 200. In this embodiment, two recesses 23 are arranged in the first plate-shaped element 4 and the second plate-shaped element 7, which together form a connection from a side that is not pressurized to a side that is pressurized of the closure device 1 train. The two recesses in the first plate-shaped element 4 can be opened or closed via a closure element 24 on the side of the first plate-shaped element 4 . Furthermore, a peripheral seal 25 is arranged on the closure element 24 so that the tightness of the closure device 1 is not influenced by the pressure compensation valve 200 . Before the closure device 1 is to be opened, the recesses 23 of the pressure compensation valve 200 can be opened in order to make it easier to open the closure device 1 .

15 shows a portion of a locking device 1 in a cross-sectional view. On an outer side 16 of the tubular frame 2 is above and below the locking element 9 an expanding by heat Sealing element 17 arranged. When exposed to heat, this can foam up, for example, and thus make contact with the frame 18 . The sealing element 17 runs in particular completely around the locking element 9 and on the entire outside 16 of the tubular frame 2. This allows a fire-protective seal to be formed between the closure device 1 and the frame 18, in particular if the tubular frame 2 forms the fold 15 of the closure device 1. Another such expanding sealing element 17 is arranged on a projection 19, so that the sealing element 17 can close the gap between the projection 19 and the frame 18 when heat develops, whereby the further sealing elements, which are arranged between the two plate-shaped elements 4, 7, are protected from the effects of heat can become. For this purpose, a further expanding sealing element 17 is arranged on the side of the second plate-shaped element 7 .

A fireproof seal is in 16 shown in a cross-sectional view. A non-combustible, non-expanding sealing layer 20 is pressed downwards by the expanding, in particular foaming sealing element 17 , which can be supported, for example, against a frame 18 or another element of the closure device 1 . This can close a gap.

17 shows a welded connection between a tubular frame 2 and a plate-shaped element 4. Between the tubular frame 2 and the first plate-shaped element 4, a temperature-resistant insulating layer 21 is arranged. Since the tubular frame 2 is formed from a rectangular profile without rounded edges, the insulating layer 21 can have a constant thickness over the entire length. The insulating layer 21 is arranged between two weld seams 32 which are designed as fillet welds. Due to the pointed edges of the rectangular profile, in particular the box profile, the tubular profile 2 can be securely welded to the plate-shaped element 4 . The heat transfer from the first plate-shaped element 4 to the tubular frame 2 is thereby limited to a minimum, namely to the area of the weld seams 32 .

18 12 shows an embodiment of a mullion 300 in a cross-sectional view. The center post 300 is designed for a double-leaf closure device 1 . A vertically arranged profile element 34 forms a stop 35 for both wings of the double-wing closure device 1 . The profile element 34 stands with an inclined contact surface 36 on a corresponding inclined installation surface 41 of an installation element 40. The profile element 34 is pulled to the left in the illustration via a fixing device 37 with an adjustable mounting device 39 and is thus pressed against the installation element 40. A seal 43 is arranged between the contact surface 36 and the installation surface 41, to which the contact pressure of the assembly device 39 is transmitted. As a result, a secure seal can be achieved between the profile element 34, the positioning element 40 and the seal 43. In the illustrated embodiment, the seal 43 is arranged in a recess 42 , the recess 42 being present in the footprint 36 . Furthermore, the seal 43 has a U-shaped cross section and can therefore be designed as a type of double seal. When assembling the mullion, after the profile element 34 has been placed, the seal 43 can be cut off flush with the front side 45 of the profile element 34 and the front side 46 of the set-up element 40 . As a result, a precisely fitting seal 43 can always be provided. Due to the beveled corresponding surfaces 36, 41, a very high contact pressure can be transferred from the profile element 34 via the seal 43 to the positioning element 40, as a result of which the sealing properties can be improved. In this embodiment, the positioning element 40 is designed as a type of wedge.

A cross-section through a double-leaf door without fire protection is in 19 shown. In this embodiment, the tube profile of the tube frame 2 is designed with rounded edges.

20 shows another cross-section through a double-leaf door with fire protection. Contrary to what is shown 19 the tubular frame 2 is designed with pointed edges as a box section. As a result, the insulating layer 21 can be arranged between the plate-shaped elements 4, 7 and the tubular frame 2, and the tubular frame 2 can be welded to the plate-shaped elements 4, 7. Regarding further explanations 15 referred.

Although the present invention has been fully described above on the basis of preferred exemplary embodiments, it is not restricted to them, but rather can be modified in a variety of ways.
