Definitions

  • Such automatic door seals are widely used and known to those skilled in the art of door seals or doors in general. They are used in particular to seal gaps between a door leaf and a floor against drafts, smoke, flames or precipitation in the case of doors with no threshold. Automatic door seals of the type mentioned at the outset are also used for external doors.
  • driving rain tightness In the case of external doors, the so-called driving rain tightness has an additional, special meaning. Driving rain tightness means that the gap between door leaves and floor is sealed by the door seal against heavy rain hitting the door, for example due to wind, and that rainwater may be present at the seal due to the wind or insufficient drainage. In particular, the pending precipitation water can then penetrate from the outside inwards, for example due to capillary forces.
  • the present invention was based on the problem of improving a seal on the lock or hinge side of a door leaf.
  • the second holding part and the second sealing part are parts of the sealing strip and as such are movable together with the other parts of the sealing strip between the release position and the sealing position.
  • the second sealing surface is aligned in such a way that it can bear against a mating surface that is perpendicular or almost perpendicular to the first sealing surface.
  • the surface is not a cut surface that results from cutting a sealing profile. Rather, it is optimized for sealing.
  • the second sealing surface preferably has the same or a similar configuration as the first sealing surface.
  • the first and/or the second sealing surface can be an outside of a web of a U-shaped sealing profile.
  • this second sealing surface can rest against a second door leaf or at the ends of a sealing part of another seal which is installed in the second door leaf.
  • This further seal can be a seal not according to the invention with the features of the preamble and the second sealing surface of the seal according to the invention is then possibly in the sealing position and with the door closed on the cut surfaces created by cutting the sealing profile, which forms the first sealing part of the first seal.
  • the further seal in the second door leaf can also be a seal according to the invention. This then also has a second sealing part with a second sealing surface. When the door is closed, the second sealing surfaces of the first and second seals then possibly rest against one another, as a result of which a continuous sealing of the entire floor gap is achieved.
  • the second sealing surface in the sealing position can bear against a frame.
  • a seal according to the invention can have a trigger which protrudes from the fastening part on the side opposite the second sealing part.
  • the trigger may be connected to the first mechanism via a trigger bar.
  • the trigger can be pressed when closing an initially open door, whereby a force is introduced into the first mechanism via the trigger rod, which causes a movement of the sealing strip from the release position into the sealing position.
  • an electric motor drive can also be provided as the drive, which is coupled to the first mechanism.
  • a gasket according to the invention may have a second attachment part attached to one end of the first holding part and in which the second holding part and the second sealing part are at least predominantly arranged.
  • the second attachment part can be connected to the first attachment part. It can be a plug connection.
  • the first and/or the second fastening part can have one or more pins which are inserted into the other fastening part.
  • This plug-in connection can correspond to a plug-in connection which is provided on an end of the first fixing part opposite the second fixing part in order to connect the first fixing part to a fixing bracket.
  • the seal according to the invention can have such a mounting bracket. This can be connected to a door leaf with a screw or something similar.
  • the second fastening part can have a hole for a screw or the like, with which the second fastening part can be fastened to a door leaf.
  • the second holding part can be connected to the first holding part by a plug connection.
  • the first and/or the second holding part can have one or more pins which are inserted into the other holding part.
  • the second holding part can also be moved in an outward direction by means of the first mechanism or by means of a second mechanism when the sealing strip moves from the release position into the sealing position.
  • the second holding part can be additionally moved in an inward direction by means of the first mechanism or by means of a second mechanism when the sealing strip is moved from the sealing position into the release position.
  • the second mechanism can be coupled to the first mechanism or the drive on the one hand and to the second fastening part on the other hand.
  • a force for moving the second sealing part outwards or inwards can then be introduced into the second mechanism via the first mechanism or the drive.
  • the second mechanism may be connected to a trip bar of the actuator.
  • the first sealing part and the second sealing part can be connected by gluing, welding or the like so that they form a continuous sealing part.
  • first sealing part and the second sealing part cannot be moved relative to each other, there is a possibility that the first sealing part and the second sealing part abut against each other without being firmly connected to each other.
  • the second sealing part can have a third sealing surface which is perpendicular or substantially perpendicular to the second sealing surface and forms an extension of the first sealing surface. This is particularly useful when the second sealing part is formed by an elbow.
  • the first sealing part can be an elastic sealing profile and the second sealing part can be an elastic angle piece.
  • the legs of the sealing piece can have the same cross section as the sealing profile.
  • One leg can the second sealing surface and another leg can form the third sealing surface.

  • the first holding part can be a rigid holding profile.
  • the second holding part can have at least one area that has the same cross section as the holding profile.
  • the second retaining part may be an angle piece having legs, one of the legs being the portion having the same cross-section as the retaining profile and the other leg also having the same cross-section as the retaining profile.
  • the seal D according to the invention has a hinge-side end E b and a lock-side end E s .
  • the seal according to the invention has a first holding part 1 and a second holding part 2 .
  • the first fastening part 1 forms a housing for the seal D.
  • This housing can be fastened to a door leaf in a known manner by means of a fastening bracket 3 which is inserted into the hinge-side end E1.
  • the seal can be installed in a groove at a lower end of the door leaf or at an upper end of the door leaf Door leaf are used.
  • the lock-side end E 2 of the seal can be attached to the door leaf by means of the second housing part 2 .
  • the first fastening part 1 is a rigid, essentially U-shaped profile.
  • a channel is provided which extends from the hinge-side end E 1 to the lock-side end E 2 .
  • the channel is open at the ends E 1 , E 2 and an upper wall of the channel formed by the web 10 has a slot extending from the hinge-side end E 1 to the buckle-side end E 2 .
  • a leg of the mounting bracket 3 and a pin 20 of the second mounting part 2 are inserted into the channel.
  • the second fastening part 2 forms a further housing which has a hinge-side wall 21 and front and rear walls 22 and a cap 23 which is fixedly connected to the walls 21,22.
  • This cap has an outer arcuate contour.
