Definitions

  • the invention relates to the field of door stops, in particular retractable in the ground door stoppers according to the preamble of claim 1.
  • Retractable doorstops are known per se: US 6,321,411 and the Japanese patent applications with the application numbers JP 2000-233665 .
  • JP 2007-837763 each show in the bottom retractable doorstops, in which a magnet is mounted in or on a moving door. If the door with the magnet is above the doorstop, it is pulled upwards directly or by a lever mechanism and engages the door.
  • the JP 2000-192707 A1 shows a doorstop, which is very flat, and is lifted only a little up, so the door must come to lie very close to the doorstop.
  • the known door stoppers cause a small vertical distance between the door and doorstop and thus corresponding structural circumstances and a precise installation of the door and / or have an injury potential in the open state.
  • the retractable stopper has a tilting element rotatably mounted about a rotation axis, which can be brought from a retracted position into a blocking position by the action of at least one triggering magnet, which is fastened to a moving object, and blocks the movement of the moving object in this blocking position.
  • the tilting element has a front lever on which a preferably elastic buffer element is arranged. This serves as a stop for the moving object.
  • the buffer element faces the moving object in the blocking position.
  • a stopper magnet or a magnetizable element is arranged on the tilting element.
  • the tilting element When approaching the release magnet in a proximity region in front of the stopper is by the action of the trigger magnet on the stopper magnet or the magnetizable element, the tilting element from the retracted position rotatable to the blocking position and is rotated before the release magnet is located above the tilting element.
  • the stopper since the stopper is tilted up before the moving object, for example the door, is located above the stopper, the stopper can be tilted relatively far upwards , This in turn allows him to restrain the door (or generally the moving object) on its outer surface, and does not need to attack a specially shaped potentially weak counterpart on the door. Furthermore, thanks to the high tilted stopper, a relatively large gap between the door and the floor can be overcome. This will be a bigger one The range of application of the stopper allows, and tolerances in the positioning of the door may be greater. For example, the vertical distance between the doorstop and the lower door edge with the trip unit can be up to 2 cm or more.
  • the tilting element on a front lever and a rear lever which face each other with respect to the axis of rotation. Due to the action of the release magnet on the rear lever, the front lever is brought into a position in which it blocks the movement of the moving object.
  • the stopper magnet or the magnetizable element is arranged on the rear lever respectively attached. In the presence of the trigger magnet in a proximity region in front of the stopper, the stopper magnet or the magnetizable element exerts a force on the tilting element, which pulls the rear lever down and thereby tilts the front lever upwards. In other words, therefore, the stopper magnet is pulled in the direction of the trigger magnet, and thereby the rear lever is rotated below the axis of rotation, and so the front lever with the buffer member is rotated upwards.
  • the distance is preferably 0.5 mm to 2 mm. This will be a violation of fingers or a Pinching objects between the buffer element or tilting element and other parts of the doorstop avoided.
  • the shape of the surface of the buffer element which faces the moving object is defined by rotation of a boundary line about the axis of rotation of the tilting element.
  • the shape may be a spherical segment or a segment of an ellipsoid of revolution, a rotary cylinder, etc.
  • a rotational angle by which the tilting element is pivotable from the retracted position to the blocking position is preferably between 40 ° and 90 °, preferably between 60 ° and 90 °.
  • an upper side of the front lever in the retracted position is aligned with a fixedly mounted cover plate and abuts in the blocking position on an upper limit formed on the cover plate.
  • a stop in the housing may also be present in the blocking position.
  • an outer stop member for damping the stop of the front lever against the upper limit in the blocking position is arranged on the cover plate and / or on the upper side of the front lever.
  • an inner stop element for damping the stop of the rear lever against the cover plate in the retracted position is arranged on an underside of the cover plate and / or on an upper side of the rear lever.
  • the triggering magnet is an electromagnet.
  • the doorstop magnet may also be an electromagnet.
  • the upturn of the doorstop then happens only with activated, so current-carrying, magnet.
  • the release magnet overruns the doorstop without moving the tilting element.
  • the moving object in particular a door, can be held in stop against the stopper when the electromagnet is switched on or energized.
  • the door is released and can be closed by a door closer.
  • the automatic closure of a fire door can be realized.
  • the doorstop falls into the lowered position and offers no obstacle.
  • the housing and / or the tilting element is formed of aluminum or another non-ferromagnetic material, whereby the magnetic forces are not dissipated.
  • the cover plate is formed of stainless steel.
  • the tilting element with the front lever and the rear lever is preferably formed in one piece and carries the buffer element attached thereto and the stopper magnet.
  • the tilting element is arranged rotatably about the axis of rotation in a housing, the housing has an upper housing part and a lower housing part, and for mounting the stopper in a substrate, first the lower housing part can be fastened in the ground and then the Upper housing part on the lower housing detachably fastened. This makes it possible to open the doorstop for cleaning purposes, the lower housing part can remain firmly anchored in the ground.
