Definitions

  • the invention relates to a door with a door leaf that can be moved between an open position, in which it at least partially exposes a wall opening, and a closed position, in which it at least partially closes the wall opening, and a guide arrangement for guiding the movement of the door leaf along at least one section of a predetermined path between the open position and the closed position.
  • Such gates can be realized in the form of so-called sectional gates, in which the gate leaf is arranged overhead in the open position approximately in a horizontal plane.
  • the door leaf consists of a plurality of door leaf elements which are connected to one another in an articulated manner with respect to joint axes running perpendicularly to the predetermined path. This enables a door leaf movement in which the door leaf runs through an arcuate section of the specified path.
  • the gate leaf is wound up into a multi-layer coil in the open position.
  • the door leaf can be formed entirely from a flexible material, such as a plastic film.
  • guide rollers can be used, which are attached to stabilizing devices running perpendicularly to the lateral edges of the door leaf.
  • the stabilizing devices can be coupled to joint arrangements arranged in the area of the lateral edges of the door leaf and fastened to the door leaf, which on the other hand can be equipped with guide rollers for guiding the movement of the door leaf.
  • Such gates are in the EP 3 176 355 B1 specified. The disclosure content of this document with regard to the design of the door leaf and the joint arrangements is hereby incorporated into this description by express reference.
  • Roller doors in which the door leaf forms a multi-layer roll above the wall opening in the open position, can also be implemented in the form of so-called high-speed doors, in which the door leaf is articulated, similar to sectional doors, from a plurality of articulated axes running perpendicular to the specified path
  • door leaf elements the height of which in the direction of the given track is, however, significantly lower than in the case of sectional doors.
  • Such goals are for example in the DE 10 2009 017 767 A1 described.
  • the disclosure content of this document is hereby included in this description with regard to the construction of the door leaf and the articulated connection of the door leaf elements by express reference.
  • guide rollers are usually attached to the door leaf and rotatably mounted with respect to the roller axes running perpendicular to the specified path and approximately parallel to the plane of the door leaf in the closed position and are accommodated in fixed guide rails, with the course of the Guide rails determines the given path.
  • the invention is based on the object of providing low-wear movable gates with low noise development.
  • this object is achieved by a further development of doors of the type mentioned at the beginning, which is essentially characterized in that the guide arrangement has at least one guide web which is arranged fixed with respect to the wall opening and extends along the predetermined path and has two outer boundary surfaces and at least two on the door leaf has fixed guide devices, wherein a first outer boundary surface of the guide bar forms a guide surface for a first guide device, and the second outer boundary surface of the guide bar forms a second guide surface for a second guide device.
  • This invention is based on the finding that the high level of noise development found in the prior art and the observed mechanical wear is primarily due to the fact that when a guide roller is accommodated in a guide rail, to ensure trouble-free operation, there is a large amount of play between the guide roller and the guide rail must become. Particularly at high door travel speeds, this leads to a movement of the guide roller in a direction perpendicular to the predetermined path, in the course of which the guide roller strikes the inner boundary surfaces of the guide rail. This not only leads to a considerable amount of noise, but also to a correspondingly high mechanical load on the guide arrangement.
  • At least one guide device has a guide roller which is rotatably mounted with respect to a roller axis running perpendicular to the predetermined path and approximately parallel to the door leaf in the closed position and which rolls on a guide surface of the door leaf when the door leaf moves.

  • the carrier can be rotated with respect to an axis of rotation that may run parallel to the roller axes and/or displaceable with respect to a translation axis that may run parallel to the roller axis on the door leaf is attached. This allows assembly inaccuracies to be compensated.

  • the electromagnet arrangement 1200 can be operated with the aid of a suitable control device in such a way that a repulsive force occurs between the electromagnet arrangement and the permanent magnets on the door leaf side.
  • the electromagnet arrangement can either be switched off or operated with reversed polarity.
  • the door leaf moves in the direction of a guide web provided in a housing 1300 and preferably at least partially encased by a sealing material, since the state of levitation created by the previous polarity of the electromagnet is eliminated. Either the repulsive forces of the magnetic field generating device on the door leaf side or of the permanent magnets on the door leaf side are then sufficient to move the door leaf.
  • the electromagnet arrangement can also be used to generate such a polarity that an attractive force is achieved between the permanent magnets on the door leaf and the electromagnet arrangement on the web side, which generates the desired displacement of the door leaf in a direction running in the direction of movement of the door leaf.
  • the 10 illustrated embodiment of the invention corresponds essentially to the basis of 8 illustrated embodiment. It differs from that based on the 8 explained embodiment that the web-side magnetic field generating devices 1100 received in a longitudinal direction of the guide bar extending groove are, as particularly evident in the Figure 10d ) and 10f ) recognizable. It can also be seen that the web-side magnetic field generating devices 1100 protrude slightly beyond the groove on their side facing away from the groove bottom. When the web-side magnetic field generating devices are made from an elastomer magnet, an additional buffer function can be achieved in this way.
  • the in 10 illustrated embodiment of the invention similar to that based on in 8 embodiment explained on the side facing away from the door leaf of the magnetic field generating devices 1010 and 1100 guide rollers 32 and 34 are provided.
  • Such supplementary mechanical guide devices in the form of guide rollers, guide pins, guide bolts or the like can be provided in all embodiments of the invention.
  • the supports 1040 for the magnetic field generating devices 1010 on the door leaf side are formed at least partially from a ferromagnetic material, in which the field lines of the magnets arranged on opposite sides of the web-side magnetic field generating device are fed back, so as to to provide a particularly strong magnetic field in the gap between the opposing permanent magnets on the door leaf.
  • the web-side magnetic field generating devices which are preferably in the form of so-called elastomer magnets, are also provided in a spirally encircling section 120 of the guide web 100 .
  • the web-side magnetic field generating devices which are preferably in the form of so-called elastomer magnets, are also provided in a spirally encircling section 120 of the guide web 100 .
  • contact-free guidance of the door leaf movement can also be achieved in the area of the spiral-shaped section, with the additional mechanical guide devices being used with particular advantage in this area.
  • the invention is not limited to the embodiment shown in the drawing. Rather, the use of doors according to the invention in the form of so-called sectional doors is also contemplated, in which the door leaf is arranged overhead in the open position approximately in a horizontal plane.
  • the invention can also be used to advantage in so-called foil gates in which the gate leaf consists of plastic foils reinforced with the aid of reinforcing profiles.
  • the guide surfaces of the guide web can also enclose an acute angle with one another.
  • the guide rollers can also be attached directly to the gate leaf members without the interposition of a joint member if the articulated connection between the gate leaf members using separate joints takes place.
  • the holders provided for the guide rollers in a door according to the invention can be made of sheet steel, die-cast aluminum or milled steel.
