  • U.S. Patent No. 2,432,293 shows a landing door catch on the cabin door with a rotating double roller lever, which in the coupled state, a vertical driver ruler on the Includes shaft door and takes it with no play.
  • Double roller lever is branched from a door operator Power take-off operated or turned via a cam disc.
  • the door clutch shown by U.S. Patent No. 5,105,916 also uses a rotating roller double lever, whereby this is turned so far by a door operating lever at the open until a ruler reaches around the shaft door and the Landing door is taken.
  • U.S. Patent No. 5,485,896 discloses a rotating Door coupling shown. Here, in the area of the door zone Roller double lever rotated by one actuator until both Rollers on the inner walls of one arranged on the landing door Fit the sheet metal duct and take the shaft door with you.
  • threshold gaps between the cabin and the floor.
  • the threshold gap must inevitably be as large as the engagement depth of the driver plus a tolerance distance of at least 5 mm. This results in threshold gaps of, for example, 20 to 25 mm.
  • Such threshold gaps are an obstacle for roller carriages with small wheels and can also pose an accident risk by pinching shoe heels. Small objects can also fall into the shaft.
  • the present invention now wants to show a new solution and the task is hereby, one To create door coupling device, which in addition to the coupling and Take the landing door a very small threshold gap between the cabin and landing door sill.
  • the invention is characterized inter alia by in that a rotatable Double roller lever designed to slide towards the shaft door is.
  • the preferred horizontal displacement and simultaneous rotation of the roller double lever is by means of a push-turn unit executed.
  • the arrangement of the push-turn unit with the roller double lever and the arrangement of the driver rulers allows one Threshold air gap which is less than 10 mm.
  • the push-turn unit with the roller double lever and the Driver rulers are on the invisible headboards Door wing attached.
  • the push-turn unit has a guide sleeve in which the Lever axis of the roller double lever is axially displaceable is, as well as a spring, which the roller double lever in the de-energized Looks back to its original position.
  • roller double lever is driven by a rotary drive Driving disc over one in one in the guide sleeve recessed longitudinal slot guided and with the lever axis connected coupling bolt with coupling ring horizontal postponed.
  • the guide sleeve has a rotary slot, which the roller double lever via a pivot pin on the lever axis at the end of the Thrust movement in the direction of the shaft door set in rotation.
  • the push-turn unit can be without Be self-propelled, one with the cabin structure firmly connected actuation curve with actuation link the thrust rotary movement of the roller double lever.
  • the push-turn unit shown in Fig.1 consists of essentially from a rotary drive 9, which with a Guide sleeve 5 is assembled.
  • a lever axis 3 In the guide sleeve 5 is a lever axis 3 with an outer bearing 13 and an inner one Bearing 14 axially displaceable and rotatably mounted.
  • the Lever shaft 3 is in the retracted starting position, in which she with her shoulder 15 on the left edge of the inner Camp 14 is pending.
  • rotatable coupling ring 6 is a spring 4 on the lever shaft 3 arranged biased.
  • a radial Coupling bolt 7 attached, which by an axial Guide slot 12 in the guide sleeve 5 protrudes outwards and in a radial slot of a drive plate 8 of the rotary drive 9 is guided and so the operative connection between rotary drive 9 and Lever shaft 3 produces.
  • roller double lever 1 In the withdrawn The roller double lever 1 has the starting position over the rollers 2 a width "a" which is smaller than the distance between the driving elements on the landing door, which guarantees would be that when driving through floors without a stop Contact with the driving element would arise. However, this is Fact not relevant to the present invention because of Roller double lever 1 in this position according to FIG. 4 withdrawn. So that you can take a shaft door with you without play the distance between the driving elements is smaller as the distance "b", or as "a + 2x", but larger than "a”.
  • the door coupling device is on one Elevator sliding door installed.
  • an instructs a door drive 22, a door motor 22, a door support Lay-up 23, left and right drive rollers 24 and one driven by the drive rollers 24 drive belt 25.
  • the Sliding door itself consists of a right wing 16.1 and a left door leaf 16.2.
  • the door leaves 16.1 / 16.2 are each with a head part 20.1 and 20.2 coupled.
  • These headboards 20.1 / 20.2 are carriers of the door leaf 16.1 / 16.2 and are for this purpose with two door rollers 18 running on a guide 17 and with each two counter pressure rollers 19 running under the guide 17.
  • the head part 20.1 is connected to the upper one via a driver 26 Strand of the drive belt 25 connected and the head part 20.2 is a driver 27 with the lower strand of the drive belt 25 connected.
  • On the head part 20.1 is a rotary drive 9 with the Roller double lever 1 arranged.
  • the double roller lever is located interfering in this representation between vertical Rulers 21, which are on the not shown Floor door and are dashed for this reason are drawn.
  • the spreading distance y corresponds to the distance between the rulers 21. With this distance y is the roller double lever 1 not fully turned out but far enough pushed out so one for taking the floor door there is a safe depth of engagement.
  • the door coupling device is here, for the sake of clarity, only for the Door leaf 16.1 with the headboard 20.1. shown and for the left door leaf 16.2 with the headboard 20.2 has been omitted. Even with the practical execution can be done with only one device be operated if the second door wing has a drive mechanism is moved from the first door leaf.
