Definitions

  • the present invention relates to a closure device for sealing building openings or rooms.
  • Closure devices are used for different applications and are used 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 locking devices in which a flat structural element can be held in a frame and fixed in a closed position.
  • the doors can be designed as fire doors, smoke protection doors, pressure doors or similar 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 section of a building or, for example, a single room.
  • Security doors and property protection doors are used, for example, in stairwells, as apartment doors or for commercial premises.
  • Property protection doors are used in particular for access to systems in the entire supply and disposal area and as interior doors, e.g. in the food industry.
  • security doors can be made of stainless steel and have a circumferential lip seal to seal them with the frame.
  • the publication shows DE 28 51 459 B1 a gas-tight door with a circumferential, inflatable sealing tube.
  • pressure medium is supplied.
  • Coupling parts for supplying the pressure medium are provided on the door leaf and the door frame. Sealing always takes place in a direction that runs in the plane of the door leaf.
  • the seal is arranged on an outward-facing peripheral side of the door leaf and thus seals the outermost edge of the door leaf with the frame.
  • a circumferential seal on a door leaf is shown.
  • the door is designed as a sliding door and has an inflatable seal that is arranged on one side of the door. This allows the door to close gas-tight when it is pressed against a frame and/or a door sill. A corresponding mechanism is provided for this purpose.
  • the US 4 722 151 A and the EN 20 2013 103304 U1 each show circumferential seals around a door leaf, which run in one plane of the door leaf.
  • the disadvantage is that the seal for all four sides of the door leaf is aligned on the outside of the door leaf's circumference, meaning that sealing is only possible in one plane. If, for example, a locking device with a specially designed fold is to be sealed, 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 aligned in sections across the plane of the door leaf is not possible.
  • Another disadvantage is that a flat object can be pushed through the door leaf at one side edge. and frame the seal can be reached and manipulated from at least one side.
  • Doors are also known from the state of the art that have a circumferential seal across the plane of the door leaf.
  • a disadvantage of such doors is that a threshold is required, since sealing a bottom edge of the door leaf is otherwise not possible.
  • the present invention is based on the object of providing an improved closure device.
  • a closure device should meet different sealing requirements on different peripheral side sections of the flat structural element, in particular on different peripheral side sections of the door leaf. This is necessary when the door is designed without a threshold and sealing should take place in different directions within the rebate.
  • sealing takes place essentially transversely to the plane of the door leaf, in that the sealing element is aligned at least in sections in a direction that is essentially transverse to the plane of the flat structural element.
  • sealing takes place in a direction that runs in the plane of the flat structural element or is aligned parallel to the plane of the flat structural element.
  • the first sealing section is arranged offset parallel to a plane that runs through the second and third sealing sections.
  • sealing sections with sealing directions that are aligned differently to one another can preferably be formed.
  • the first sealing section can be arranged in a different plane than the second and third sealing sections.
  • In another plane means in particular in a parallel offset plane of the structural element. This allows any area of a fold to be sealed, while at the bottom edge a seal can be made close to an outer side of the closure device that is not in the plane of the fold.
  • An alignment or sealing essentially transverse or parallel to a plane or to a direction is to be understood in particular to mean that, within the framework of manufacturing tolerances and/or unevenness, an alignment or sealing takes place in the described direction.
  • a direction parallel or transverse to the plane here to the plane of the flat structural element or to a plane of the floor, can deviate by a few degrees from a parallel or right-angled alignment.
  • the orientation of the sealing element on different circumferential side sections of the flat structural element can be selected independently of one another, even if a continuous sealing element is formed.
  • sealing can be achieved in a transition region from one circumferential side section to the next.
  • the first sealing section can be sealingly contacted with a floor in a closed position of the closure device 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 flat structural element.
  • a pressure medium for example by inflating the seal with compressed air, in particular parallel to or within the plane of the flat structural element.
  • the second sealing section and the third sealing section in the closed position can also be sealingly contacted with a frame element, such as a casing, in the same direction essentially transverse to the plane of the flat structural element by filling the seal with a pressure medium, for example by inflating the seal with compressed air.
  • a pressure medium for example by inflating the seal with compressed air.
  • a certain contact with the frame can also be provided before inflation, but without significant pre-tensioning of the seal. Increased tightness is only achieved by filling the seal.
  • a threshold-free closure device with a sealing element 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 a gas-tight connection is formed between the flat structural element and the frame element and the floor in at least two sealing sections in two different directions.
  • the seal transverse to the plane of the structural element can be orthogonal to the plane and can be aligned at any angle to the plane.
  • a direction transverse to the plane of the flat structural element in which sealing may be required is arranged, for example, on a side edge within a fold, whereby this area is not accessible when the locking device is closed. 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 sealingly contacted with the ground, wherein the seal is aligned in a direction parallel to a plane of the flat structural element.
  • 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 designs, 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 in a closed position of the closure device, the flat structural element can be sealed with the frame element and with the floor, whereby the seal can meet the requirements for object protection doors.
  • the fillable sealing element preferably contains an elastic material, for example a silicone or rubber material.
  • the sealing element can be made from a hollow rubber profile that is provided as a profile strand with end plugs or vulcanized to form an endless ring.
  • the sealing element can have a profile cross-section that is constant over its length.
  • 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 each other by means of a 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 the floor. This advantageously allows larger Sealing gaps can be bridged. A further advantage is that the seal does not rub against the counter surface during the closing or opening process.
  • the volume of the sealing element changes, it can be reshaped and/or inflated, for example, from a flattened shape to a substantially circular shape.
  • the sealing element can advantageously be returned to its original shape when unfilled, so that sealing with the same sealing element can be repeated as often as required.
  • 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 flat 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 for sealing. Consequently, the sealing element in the second and third sealing sections exerts a stroke in a direction that is aligned essentially transversely to the plane of the flat structural element.
  • the sealing element can be connected directly or indirectly to the flat structural element.
  • the sealing element can be connected to the flat structural element via a support structure that specifies or supports the course of the sealing element, for example a groove running along the edge of the door.
  • the sealing element can be clamped to parts of the flat structural element, for example by clamping means.
  • the sealing element can also be screwed and/or glued to the flat structural element.
  • the structural element can, for example, have a receiving surface that is in particular groove-shaped and corresponds to the shape or course of the sealing element.
  • a sealing section is preferably assigned to a peripheral side section of the flat structural element.
  • the peripheral side sections of the structural element form in particular two side edges, a bottom edge and a top or ceiling edge. Adjacent peripheral side sections are preferably aligned at least substantially orthogonally, opposite peripheral side sections are preferably aligned at least substantially parallel to one another. Of course, these alignments can be adapted to non-rectangular closure devices according to their geometry.
  • the first sealing section can be arranged between the second and the third sealing section.
  • This allows an at least U-shaped sealing element to be formed, which is arranged at least along two opposite peripheral side sections of the door leaf, i.e. along two side edges that are in contact with the frame element, and along the bottom-side peripheral side section of the door leaf, i.e. along the bottom edge.
  • 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 continuous sealing element is formed, which is arranged circumferentially around the flat structural element.
  • a circumferential, in particular annular, seal wherein the continuous sealing element can have differently aligned sealing surfaces in different sealing sections, which in the filled state nevertheless seal equally.
  • the sealing element can be rotated or twisted in order to achieve a change in alignment.
  • the fourth sealing section can be sealingly contacted with the frame element in a direction substantially transverse to the plane of the planar structural element or in a direction parallel to a plane of the planar structural element.
  • a sealing device can be formed which enables sealing substantially transverse to the plane of the planar structural element on two side edges and on the upper edge of the planar structural element, while sealing can take place on the bottom edge in the direction of the plane of the planar structural element, and in particular transverse to the surface of the floor.
  • the fourth sealing section can thus be sealingly contacted with the frame element, in particular a casing, on the upper edge in the same way as the second and third sealing sections on the side edges in the closed position in the same direction substantially transverse to the plane of the planar structural element.
  • the upper edge can be a ceiling edge.
  • the fourth sealing section can be sealingly contacted with a ceiling when the closure device is in a closed position.
  • 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 flat structural element.
  • the fourth sealing section running along a ceiling edge can additionally be arranged offset in parallel with respect to a plane that runs through the second and third sealing sections, with essentially the same advantages as with the first sealing section.
  • the first sealing section can be connected to the second sealing section and the third sealing section via a respective deflection section, wherein the deflection section is designed as a sealing section.
  • a deflection section is to be understood as a connecting section that connects adjacent sealing sections in such a way that they can be arranged in different planes.
  • 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 itself therefore 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 circumferential frame element is created.
  • the deflection section preferably contains the same material as the sealing sections.
  • the deflection section can enable a connection of the sealing element from the plane parallel to the flat structural element to a plane transverse to the flat structural element.

  • 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 flat structural element.
  • An outer radius, which preferably faces away from the flat structural element is preferably twice as large as the inner radius.
  • the deflection section can have a double-curved shape, wherein a first curved section and a second curved section are each arranged in a different plane, each of which runs substantially transversely to the plane of the structural element.
  • the two sections are arranged in particular adjacent, preferably one behind the other, along a length of the deflection section.
  • the first section can be formed from an angled section which is arranged in a plane substantially transversely to the plane of the structural element.
  • the second section can be formed from an angled section which is arranged in a plane substantially parallel to a plane of the floor.
  • a seal can be formed over the entire length of the deflection section, wherein the deflection section can be sealingly contacted at least in sections with the frame element in the direction transverse to the structural element.
  • the deflection section can be sealingly contacted at least in sections with a base seal, in particular in the direction parallel to the flat structural element.
  • the seal can be produced by filling the seal.
  • 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 respect to different curved sections, so that a gap between the flat structural element and the frame element or the floor can also be closed and sealed in a transition area between two sealing sections.
  • the stroke can therefore be aligned in sections in a direction that corresponds to the plane of the flat structural element.
  • the stroke can be aligned in sections in a direction that is orthogonal to the plane of the flat structural element.

  • the sealing element 2 is aligned in the direction Z as in the second and third sealing sections 3b, 3c. It would also be conceivable that in the fourth sealing section 3d, the sealing element 2 is aligned against the direction X in order to seal a gap in the area of the fold.
  • Fig.10 shows a sectional view along the plane BB from Fig.7 . This corresponds to a view according to Fig.5 , where Fig.10 the sealing element 2 is integrated in the flat 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.
  • the sealing element 2 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.
  • the sealing element 2 contacts the counter surface 18, so that a gap between the flat structural element 12 and the base 13 is sealed at the base edge of the structural element 12.
  • Fig. 11 shows another possible section along the plane EE from Fig.2 .
  • 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 be sealingly contacted with the base 13 in the direction X.
  • 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 is designed as an arc element, in particular as a doubly curved deflection section, along the deflection section 7 up to the third sealing section 3c. This enables the sealing element 2 to be guided from the YZ plane into the XY plane.
  • the first sealing section 3a can be arranged at any distance from the second and third sealing sections 3b, 3c.
  • the shape of the sealing element 2 is not limited to the shape shown.
  • the fillable sealing element 2 can be formed by any hollow cross-section that is capable of enabling a stroke 21, in particular aligned in only one direction.
  • the sealing element 2 is L-shaped as in Fig.5 is formed, however, the second and third sealing sections 3b, 3c can be aligned at any angle with respect to the plane XZ.
  • the sealing element 2 in the second and third sealing sections 3b, 3b can be aligned in a direction inclined to the direction Z, in particular at an angle between 0° and 45°, preferably between 10° and 20°. Consequently, the sealing element 2 in at least the second and third sealing sections 3b, 3c can be sealed with a surface of a frame element which is formed inclined. The same applies in particular to the fourth sealing section 3d with respect to a direction Y.
