Description

FIELD OF THE INVENTION

The present invention relates to a closure device for sealing building openings or rooms.

TECHNICAL BACKGROUND

Closing devices 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 or property protection doors are flat closure devices in which a flat structural element can be held in a frame and fixed in this in a closed position. The doors can be designed 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 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 and property protection doors are used, for example, in stairwells, as apartment entrance doors or for commercial premises. Security doors are used particularly for access to systems in the entire supply and disposal area and as interior doors, e.g. B. used in the food industry.

Property protection doors can be made of stainless steel, for example, and have a circumferential lip seal for sealing with the frame.

This is how the pamphlet shows DE 28 51 459 B1 a gas-tight lockable door with a circumferential, inflatable sealing hose. In a closed position of the door, pressure medium is supplied. Coupling parts for supplying the pressure medium are provided on the door leaf and on the door frame. A seal is always made in one direction, which runs in the plane of the door leaf. The seal is arranged on an outwardly directed peripheral side of the door panel and thereby seals the outermost edge of the door panel with the frame.

The disadvantage is that the seal for all four sides of the door leaf is aligned on an outside of a circumference of the door leaf, so that sealing is only possible in one plane. For example, if a locking device is to be sealed with a specially designed fold, the seal cannot be variably adjusted in the sealing direction on different sides of the door leaf, such as a side edge or a bottom edge. A seal that is partially aligned transversely to the plane of the door leaf is not possible.

Equally disadvantageously, the seal can be reached and manipulated at least from one side on a side edge of the door leaf by pushing a flat object between the door leaf and the frame.

Doors are also known from the prior art which have a peripheral seal transverse to the plane of the door leaf. The disadvantage is that doors of this type require a threshold, since otherwise it would not be possible to seal a bottom edge of the door leaf.

SUMMARY OF THE INVENTION

Against this background, the present invention is based on the object of specifying an improved closure device.

According to the invention, this object is achieved by a closure device having the features of patent claim 1 .

Accordingly, it is provided:
A closure device for sealing building openings or rooms, in particular property protection doors, with a flat structural element, in particular a door leaf, with a fillable sealing element which is connected to the flat structural element, with the fillable sealing element having at least three connected sealing sections, with a first sealing section along a The bottom edge is aligned essentially parallel to a plane of the planar structural element, so that the first sealing section can be sealingly contacted with a floor when the closure device is in a closed position, and wherein a second sealing section and a third sealing section are each along a side edge and essentially parallel to a plane of the planar structural element are aligned so that the second sealing section and the third sealing section in the closed position with a frame element, in particular a frame, are each in the same R direction can be contacted in a sealing manner essentially transversely to the plane of the planar structural element.

The finding on which the present invention is based is that a locking device should meet different sealing requirements on different peripheral side sections of the planar structural element, in particular on different peripheral side sections of the door leaf. This is necessary if the door is designed without a threshold and sealing is to take place in different directions within the fold.

The idea on which the present invention is based is to align a seal differently in sections. On the one hand, in a sealing section, sealing occurs essentially transversely to the plane of the door leaf, in that the sealing element is oriented at least in sections in a direction that is oriented essentially transversely to the plane of the planar structural element. On the other hand, in a further sealing section, sealing takes place in a direction that runs in the plane of the planar structural element or is aligned parallel to the plane of the planar structural element.

An alignment or a seal essentially transverse or parallel to a plane or to a direction is to be understood in particular to mean that within the scope of manufacturing tolerances and/or unevenness, an alignment or seal takes place in the described direction. As a result, a direction parallel or transverse to the plane, here to the plane of the planar structural element or to a plane of the floor, can deviate by a few degrees from a parallel or right-angled alignment.

In other words, the alignment of the sealing element on different peripheral side sections of the planar structural element, such as on a bottom edge and a side edge, can be selected independently of one another, even if a coherent sealing element is formed. Advantageously, even with such a circumferential seal that changes in the sealing direction, a seal can take place in a transition region from one circumferential side section to the next.

In particular, when the closure device is in a closed position, the first sealing section can be sealingly contacted with a base by filling the seal with a pressure medium, for example by inflating the seal with compressed air, in particular parallel to or within the plane of the planar structural element. By filling the seal, a gap to the floor required for opening and closing the door is closed and the seal is pressed or pretensioned in a sealing manner against the floor.

In particular, the second sealing section and the third sealing section are also in the closed position with a frame element, such as a frame, in the same direction essentially transverse to the plane of the planar structural element by filling the seal with a pressure medium, for example by inflating the seal with Compressed air, sealing contact possible. A certain contact with the frame can also be provided prior to inflation, but without appreciable prestressing of the seal. An increased tightness is only achieved by filling the seal.

A threshold-free closure device with a sealing element is therefore proposed, wherein in a closed position the sealing element interacts with counter surfaces of the frame element and with the floor when pressure medium is supplied, so that in at least two sealing sections in two different directions a gas-tight connection between the flat structural element and the frame member and the floor is formed. The sealing across the plane of the structural member can be orthogonal to the plane as well as oriented at any angle to the plane.

A direction transverse to the plane of the planar structural element, in which a seal may be necessary, is arranged, for example, on a side edge within a fold, with this area being closed when the closure device is closed is not accessible. In a closed state, the seal experiences additional pressure from the flat structural element, which presses against the frame element in the area of the fold. This can support the sealing effect.

The first sealing section can be contacted in a sealing manner with the floor, with the seal being aligned in a direction parallel to a plane of the planar structural element. This allows sealing directly down to the ground if the closure device does not have a sill. The floor or a contact surface on the floor is therefore preferably arranged transversely to the plane of the structural element.

The fillable sealing element can have different configurations, for example it can be filled with a pressure medium, pneumatically or hydraulically. In an unfilled state, the sealing element has a smaller volume, in particular a smaller cross section, than in a filled state. As a result, when the sealing element is filled when the closure device is in a closed position, the planar structural element can be sealed with the frame element and with the floor, with the seal being able to meet the requirements for property security doors.

The fillable sealing element preferably contains an elastic material, for example a silicone or rubber material. For example, the sealing element can be formed from a rubber hollow profile, which is provided as a profile strand with end plugs or is vulcanized to form an endless ring. The sealing element can have a profile cross section that is constant over the length. Likewise, the profile cross-section in different sealing sections can be adapted to different requirements, in particular to different distances to be bridged from the frame element or from the floor, with different cross-sectional shapes and cross-sectional sizes. The sealing element preferably contains materials such as silicone, EPDM rubber, CR rubber and/or NBR rubber.

The sealing element is preferably connected to a pressure connection. Adjacent sealing sections are connected to one another to carry pressure medium, so that only one pressure connection is required. The sealing element can be activated by supplying pressure medium, whereby it is pressed against the frame element and against the floor. Advantageously, larger sealing gaps can also be bridged as a result. A further advantage arises from the fact that the seal does not rub against the opposite surface during the closing or opening process.

When the volume of the sealing element changes, it can be deformed and/or inflated, for example, from a flattened shape to a substantially circular shape. Advantageously, the sealing element can be restored to the initial shape of the unfilled state, so that sealing with the same sealing element can be repeated as often as desired.

When the volume increases, the fillable sealing element can in particular exert a stroke of more than 5 mm, in particular 5 mm to 20 mm, preferably a maximum of 15 mm, so that a gap between the planar structural element and the frame element can be closed and sealed. The direction in which the stroke is essentially carried out corresponds to the direction in which the respective sealing section is aligned in a sealing manner. Consequently, the sealing element in the second and third sealing section exerts a stroke in a direction which is essentially aligned transversely to the plane of the planar structural element.

The sealing element can be connected directly or indirectly to the planar structural element. For example, the sealing element via a support structure that specifies or supports the course of the sealing element, for example a groove running along the door edges, be connected to the flat structural element. In a further embodiment, the sealing element can be clamped, for example by clamping means, to parts of the planar structural element. Likewise, the sealing element can be screwed and/or glued to the planar structural element. For better assembly, the structural element can have, for example, a receiving surface which is in particular designed in the shape of a groove and corresponds to the shape or the course of the sealing element.

A sealing section is preferably assigned to a peripheral side section of the planar structural element. The peripheral side sections of the structural element form in particular two side edges, a bottom edge and a top or top edge. Adjacent peripheral side sections are preferably aligned at least essentially orthogonally, opposite peripheral side sections are preferably aligned at least essentially parallel to one another. Of course, in the case of non-rectangular closure devices, these orientations can be adapted according to their geometry.

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, the first sealing section can be arranged between the second and the third sealing section. As a result, an at least U-shaped sealing element can be formed, which is arranged at least along two opposite peripheral side sections of the door panel, ie along two side edges that are in contact with the frame element, and along the bottom peripheral side section of the door panel, ie along the bottom edge.

According to an advantageous embodiment, the sealing element can have a fourth sealing section, which is connected to the second and the third sealing section and is aligned along an upper edge of the structural element, so that a coherent sealing element is formed, which is arranged circumferentially around the planar structural element. Advantageously, a circumferential, in particular ring-shaped, seal is possible as a result, in which case the coherent sealing element can have differently aligned sealing surfaces in different sealing sections, which nevertheless seal equally in the filled state. The sealing element can be turned or twisted, in particular in the transition areas between the sealing sections, in order to achieve a change in the orientation.

According to one development, the fourth sealing section can be sealingly contacted with the frame element in a direction essentially transverse to the plane of the planar structural element or in a direction parallel to a plane of the planar structural element. In this way, a sealing device can be formed which allows a seal essentially transverse to the plane of the planar structural element on two side edges and at the top edge of the planar structural element, while at the bottom edge a seal is made in the direction of the plane of the planar structural element, and in particular transverse to the surface of the ground can take place. In one embodiment, the fourth sealing section can thus be sealingly contacted at the top edge in the same way as the second and third sealing section at the side edges in the closed position with the frame element, in particular a frame, in the same direction essentially transverse to the plane of the planar structural element.

In a further embodiment, the top edge can be a ceiling edge. In this case it is conceivable to seal the fourth sealing section against a ceiling in the same way as for the bottom edge. In particular, the fourth sealing section can be sealingly contacted with a cover when the closure device is in a closed position. In particular, the sealing contact can be produced by filling the seal with a pressure medium, for example by inflating the seal with compressed air, parallel to or within the plane of the planar structural element.

According to a preferred embodiment, the first sealing section can be offset parallel with respect to a plane that runs through the second and third sealing sections. In this way, preferably sealing sections can be formed with sealing directions that are aligned differently to one another. In particular, the first sealing section can be arranged in a different plane than the second and third sealing section. In another level means in particular in a parallel offset level of the structural element. This allows any portion of a fold to be sealed while at the bottom edge a seal can be made close to an outside of the closure device that is not in the plane of the fold.

The same applies in the case of a fourth sealing section that can be contacted in a sealing manner against the ceiling. In other words, according to one embodiment, the fourth sealing section running along a ceiling edge can also be offset in parallel with respect to a plane that runs through the second and third sealing sections, with essentially the same advantages as in the case of the first sealing section.

According to a particularly preferred embodiment, the first sealing section can be connected to the second sealing section and the third sealing section via a respective deflection section, with the deflection section being designed as a sealing section. On the one hand, there is a connecting section as a deflection section to understand that connects adjacent sealing sections such that they can be arranged in different planes. Furthermore, the deflection section enables adjacent sealing sections to be connected in such a way that when the sealing sections are filled, in particular pneumatically or hydraulically, the pressure medium can flow from one sealing section into an adjacent sealing section. The deflection section therefore itself forms a section of the sealing element as a type of deflection sealing section.

The deflection section can be a preformed deflection sealing element, which is preferably formed in one piece with the sealing sections, so that a one-piece sealing element in the form of a peripheral frame element is produced. The deflection section preferably contains the same material as the sealing sections.

According to an advantageous embodiment, the deflection section can enable the sealing element to be connected from the plane parallel to the planar structural element to a plane transverse to the planar structural element. The deflection section can in particular be designed as a curved element or as a type of elbow. In one embodiment, the deflection section has a shape that is curved once, in particular a shape that is curved once in one plane. The deflection section is preferably designed as an angle element, with a first leg contacting the first sealing section and a second leg contacting the second or third sealing section. The deflection section advantageously has a deflection with an inner radius of more than 10 mm, in particular in a range from 10 mm to 30 mm, preferably 15 mm to 20 mm. The inner radius is preferably arranged on a side of the deflection section that faces the planar structural element. An outer radius, which preferably faces away from the planar structural element, is preferably twice as large as the inner radius.

According to an advantageous embodiment, the deflection section can have a double-curved shape, with a first curved section and a second curved section each being arranged in a different plane, which in each case runs essentially transversely to the plane of the structural element. The two sections are in particular arranged adjacently, preferably one behind the other, along a length of the deflection section. The first portion may be formed from an angled portion disposed in a plane substantially transverse to the plane of the structural member. The second portion may be formed of an angled portion disposed in a plane substantially parallel to a plane of the floor.

According to a further embodiment, a seal can be formed over a complete length of the deflection section, the deflection section being able to contact the frame element in a sealing manner at least in sections in the direction transverse to the structural element. Alternatively or additionally, the deflection section can be contacted at least in sections with a bottom seal, in particular in the direction parallel to the planar structural element. In particular, the seal can be produced by filling the seal. Advantageously, the direction in which the deflection sealing element exerts a stroke during filling is aligned differently along the length of the deflection section, in particular with regard to different curved sections, so that a gap between the planar structural element and the frame element or the base is also present in a transition area between two Sealing sections can be closed and sealed. The stroke can therefore be oriented in sections in a direction that corresponds to the plane of the planar structural element. Likewise, the stroke can be oriented in sections in a direction that is oriented orthogonally to the plane of the planar structural element.

It is also conceivable that the fourth sealing section is connected to the second sealing section and the third sealing section via a respective deflection section. As a result, the fourth sealing section can be arranged offset parallel to the second and third sealing sections. In such an embodiment, the sealing element can have a total of four deflection sections. The features and advantages explained apply to all deflection sections.

According to one development, a first section of the sealing element can be arranged at an angle to a second section of the sealing element, with the first section in particular comprising the second and third sealing section and the second section comprising the first sealing section. In this embodiment, the sealing element can preferably form a peripheral frame element that is in particular L-shaped. L-shaped means that a first section of the sealing element is arranged at an angle to a second section of the sealing element. The deflection is made possible in particular by the deflection section, which is arranged between the first and the second or between the first and the third sealing section.

According to one embodiment, the sealing element can be a pneumatically operable sealing element. In this way, a change in volume can be achieved by introducing compressed air into the sealing element. The supply takes place in particular through a connection element, in particular a compressed air connection element, which is triggered in particular when the closure device is closed.

In an advantageous embodiment, the sealing element can be expandable by being filled, with the sealing element having a smaller volume in an unfilled position than in a filled position. Advantageously, the sealing element can be made of an elastic material that is combined with one of the already mentioned materials of the sealing element.

According to an advantageous embodiment, a connection element for supplying a pressure medium can be provided, which is connected to the sealing element. The connection element is preferably designed for the supply of a pressure medium such as compressed air. It can therefore be designed as a compressed air connection element. Only one connection element is preferably provided in order to feed pressure medium into all sealing sections. This is possible in that respectively adjacent sealing sections are connected to one another to carry pressure medium, in particular via the deflection sections.

According to one embodiment, a sealing frame can be provided for receiving and guiding the sealing element. Advantageously, the guiding and mounting of the sealing element on the flat structural element can be easily implemented in this way. The sealing frame can be designed as a one-piece molded part and, in particular, can contain metal. The sealing element can, for example, be glued, clamped or screwed to the sealing frame.

According to one embodiment, the sealing frame can have at least three, in particular four, sealing frame sections, each sealing frame section being designed to accommodate and guide a sealing section. A first sealing frame section is advantageously designed to receive and guide the first sealing section, a second sealing frame section to receive and guide the second sealing section and a third sealing frame section to receive and guide the third sealing section. For this purpose, the sealing frame preferably has a receiving surface for the sealing element on each sealing frame section. All receiving surfaces are preferably connected to one another, so that a coherent sealing element can be guided along the sealing frame sections. A deflection element which corresponds to the deflection sections and enables the deflection section to be guided can preferably be formed between adjacent sealing frame sections. For this purpose, a receiving surface for receiving and guiding the deflection section is preferably formed on the deflection element. The receiving surface is preferably designed to correspond to the shape of the deflection section. The receiving surface can run spirally around the deflection element, at least in sections. Fastening of the sealing element is preferably possible in or on the receiving surface. The sealing element can be clamped to the receiving surface, for example by clamping means that are integrated in particular in the receiving surface. Likewise, the sealing element can be screwed and/or glued. The deflection element is part of the sealing frame. The sealing element is preferably in contact with the sealing frame over the entire length.

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 sealing element 2. The sealing element 2 can, for example, on or in a flat Structural element of a locking device (not shown), in particular mounted or integrated on a door leaf. In this embodiment, the sealing element 2 has four sealing sections 3a to 3d, which form a coherent sealing element 4 in the form of a peripheral frame element 8 and can be arranged along two side edges, a bottom edge and a top edge of the structural element. The sealing element 2 lies on the one hand in a plane XY, which is also spanned by the planar structural element. The XY plane is in 2 shown.
• 2 shows an isometric representation of the sealing element 2 from 1 . It can be seen that parts of the sealing element 2 lie in a further plane YZ, which is orthogonal to the XY plane. It becomes clear that the first sealing section 3a does not lie in the XY plane which is spanned by the second, third and fourth sealing section 3b, 3c, 3d. The peripheral frame element 8 is accordingly L-shaped, with a first section 14a of the L-shape lying in the XY plane and a second section 14b of the L-shape lying in the YZ plane.
• 3 shows a schematic isometric view of a deflection section 7, which is shown in a connection between the first sealing section 3a and the third sealing section 3c, for example for a sealing element 2 2 . In this embodiment, the deflection section 7 has a possible double-curved shape, with a first curved section 7a and a second curved section 7b each being arranged in a different plane, which in each case runs essentially transversely to the plane of the structural element. The two sections 7a, 7b are arranged one behind the other along a length of the deflection section 7. The first section 7a is designed as an angled section, which is arranged in a plane XZ essentially transverse to the plane of the structural element. The second section 7b is also formed as an angled portion located in a plane YZ substantially parallel to a plane of the bottom. In the illustrated embodiment, the alignment is shown essentially transversely or essentially parallel to the respective plane as an alignment transversely or parallel without possible manufacturing tolerances. The structural element is arranged in an XY plane and is not shown for reasons of clarity. A seal can be formed over the entire length of the deflection section 7, wherein the deflection section 7 can be sealingly contacted at least in sections with the frame element in the Z direction transverse to the structural element and/or at least in sections with a base in the X direction. The deflection cut is therefore preferably formed in sections along the bottom edge and in sections along a side edge of the structural element. The deflection section 7 is shown only schematically, it being possible for the seal in the deflection section 7 to have any cross section. In particular, the deflection section 7 is designed in one piece.
• 4 shows a sectional view along the plane AA 1 . The sealing element is not limited to the illustrated cross-sectional shape. It can be seen that the sealing element 2 is aligned in the Z direction on the second and third sealing section 3b, 3c. Consequently, a seal with a frame element of the closure device (not shown) in the Z direction is possible with the second and third sealing section 3b, 3c. A connection element 16 for supplying pressure medium is provided on the sealing element 2 and, in this embodiment, is connected to the sealing element 2 at the second sealing section 3b.
• figure 5 shows a sectional view along the plane BB 1 . In this representation, an L-shape of the sealing element 2 can be seen, with the fourth sealing section 3d being oriented in the Z direction and the first sealing section 3a being oriented in the X direction is. This is made possible by the fact that the first sealing section 3a is offset in parallel with respect to the plane XY, which is formed by the second and third sealing sections 3b, 3c. A distance in the Z-direction between the second or third sealing section 3b, 3c and the first sealing section 3a is determined by the geometry or shape of the deflection section 7 . The deflection section 7 is designed as a kind of angle element, which is arranged in the plane XZ. Thus, a first leg of the angle element is oriented in the -X direction and a second leg is oriented in the -Z direction. Consequently, the first section 14a of the sealing element 2 is arranged at an angle to the second section 14a of the sealing element 2 .
• 6 shows a sectional view along the plane DD 1 . The sealing element 2 is made of silicone or a rubber material, for example. In an unfilled state 19, the sealing element 2 has a smaller volume than in a filled state 20. As a result, when the sealing element 2 is filled in a closed position 17 of the closure device, the planar structural element 12 can be sealed with the frame element 11, for example shown in 7 . The decisive factor here is that when the volume is increased, a stroke 21 of preferably up to 10 mm can be formed, so that a gap between the planar structural element 12 and the frame element 11 is sealed. The direction in which the stroke 21 is executed corresponds to the direction in which the respective sealing section 3a to 3d is aligned.
• 7 shows an embodiment of a closure device 10 with a frame element 11 and a flat structural element 12. The closure device 10 is shown in the closed position 17 and can be a property protection door 1, for example.
• 8 12 shows a sectional view through the side edges of the structural element 12 along the plane AA 7 . This corresponds to a view 4 , where in 8 the sealing element 2 is integrated in the planar structural element 12, in particular in the door leaf. The sealing element 2 can be arranged at any point in the planar structural element 12 . For example, this can be arranged between an inner shell and an outer shell. The second sealing section 3b and the third sealing section 3c can be sealingly contacted with the frame element 11 in the Z direction, so that a gap in the region of the fold between the planar structural element 12 and the frame element 11 can be closed.
• 9 shows a sectional view through the bottom edge and through the top edge along the plane BB 7 . It can be seen that the sealing element 2 is deflected in the first sealing section 3a in such a way that it can make sealing contact with the base 13 in the X direction. In the fourth sealing section 3d, the sealing element 2 is aligned in the Z direction, as in the second and third sealing sections 3b, 3c. It would also be conceivable for the sealing element 2 in the fourth sealing section 3d to be aligned counter to the direction X in order to seal a gap in the area of the fold.
• 10 shows a sectional view along the plane BB 7 . This corresponds to a view figure 5 , where in 10 the sealing element 2 is integrated in the planar structural element 12, in particular in the door leaf. The sealing element 2 is shown in the unfilled position 19 and in the filled position 20 . In the unfilled position 19 the sealing element 2 is arranged at a distance from a counter-surface 18 which forms an upper edge of the base 13 . In the filled state 20, the sealing element 2 contacts the counter surface 18, so that at the bottom edge of the structural element 12 a gap between the planar structure element 12 and the base 13 is sealed.
• 11 shows another possible sectional representation along the plane EE 2 . In this representation, the fillable sealing element 2 is shown with a possible cross-sectional shape as a detailed sectional view. The sealing element is aligned on the sealing section 3a in the direction of the base 13, so that the sealing element 2 in the first sealing section 3a can make sealing contact with the base 13 in the X direction. The first sealing section 3a is connected to the third sealing section 3c via a deflection section 7 . The deflection section 7 and the third sealing section 3c are not shown in the sectional view in this illustration. The dashed lines therefore show that the sealing element 2 along the deflection section 7 up to the third sealing section 3c is designed as a curved element, in particular as a double-curved deflection section. This enables the sealing element 2 to be guided from the YZ plane into the XY plane. Depending on the design of the deflection section 7, the first sealing section 3a can be arranged at any distance from the second and third sealing section 3b, 3c.

Although the present invention has been fully described above with reference to preferred exemplary embodiments, it is not restricted to them, but rather can be modified in a variety of ways. In particular, the shape of the sealing element 2 is not limited to the shape shown. In principle, the fillable sealing element 2 can be formed by any hollow cross section that is able to allow a stroke 21, in particular aligned in only one direction.

It is also conceivable that the sealing element 2 is L-shaped as in figure 5 is formed, but with the second and third sealing portions 3b, 3c at an arbitrary angle may be aligned with respect to the XZ plane. As a result, the sealing element 2 can be aligned in the second and third sealing section 3b, 3b in a direction inclined to the Z direction, in particular at an angle between 0° and 45°, preferably between 10° and 20°. As a result, the sealing element 2 can be sealed in at least the second and third sealing sections 3b, 3c with a surface of a frame element which is designed to be inclined. The same applies in particular to the fourth sealing section 3d with respect to a direction Y.
