Definitions

  • Door locking device for retrofitting in an automatic sliding door of an elevator car, which is coupled to the landing door by means of curves and drivers on the floor stops and is opened and closed together with this, the locking device making it impossible to open the car door from inside the car if it is this between two floors respectively. outside the door opening zone of a floor.
  • the present invention is therefore based on the object of providing a door locking device which can be retrofitted to most existing, non-compliant door systems, which does not require any change to the existing construction, which is simple and safe, and which can be carried out in the shortest possible time. and material costs can be installed.
  • the advantages achieved by the invention consist essentially in the fact that the subsequent installation of the device means no intervention in an existing construction, that the device can be installed in a short time and that it is simple and inexpensive to manufacture.
  • FIG. 1 shows a centrally opening elevator sliding door with a left door leaf 10 and a right door leaf 11.
  • the two door leaves 10 and 11 are attached to rollers 12 which run on a rail 13 and are opened and closed by a door drive (not shown) .
  • the coupling and driver device is mounted on the left door wing, which essentially consists of a fixed curve 8, a movable curve 9 and a curve mechanism 14.
  • the door locking device installed on this automatic door has a hook holder 2 on the top left of the right door leaf 11, a locking hook 1 attached to the top right of the left door leaf 10 and in the locked position, a compression spring 7 holding the locking hook 1 in the locked position, one with some clamps 6 on the left door leaf 10 attached wire pull jacket 5, a pull wire 4 running in the wire pull jacket 5 and a rocker 3 actuating the pull wire 4 and mounted on the movable curve 9.
  • the rocker 3 has a bevel 32 at the lower and upper end. Shown in broken lines is 34 a deflection roller and 33 a flexible traction means. 2 shows the locking mechanism with the corresponding parts.
  • the hook holder 2 has a support 17 for attachment, as well as a horizontal part, each with a left and right upward bent stop edge 20.
  • the right stop edge 20 has no function in this disposition, but serves the more universal use of the hook holder 2 for left and right application.
  • the locking hook 1 is movably mounted on a support 15 mounted on the left door wing about a pivot point 16.
  • the right end of the locking hook 1 is designed as a downwardly directed nose 18 which engages behind the stop edge 20.
  • the left part of the locking hook 1 has an inserted screw bolt 19 with screw head, fastening and Lock nuts.
  • the compression spring 7 is clamped between the bracket 6 and the screw head of the screw bolt 19 and holds the locking hook 1 in the latched position shown.
  • the pull wire 4 is formed at its end as a ring eyelet and clamped between the screw head and the nut of the screw bolt 19. The lever ratio can be changed with the screw bolt 19.
  • the coupling and driver mechanism shown in cross section in FIG. 3 additionally shows a bearing support 31 directed from the fixed curve 8 to the left with a pivot point 25 about which the movable curve 9 moves within a limited angle.
  • the movable curve 9 has the position while the elevator is moving.
  • the rocker 3 is attached to the left flank of the movable curve 9.
  • the rocker 3 consists of an upward pressure leg 23 and a downward pull leg 22.
  • the two legs 22 and 23 of the rocker 3 are arranged at a fixed invariable angle of, for example, 130 ° to 150 ° to each other.
  • the rocker 3 has a vertical length, not visible in this FIG.
  • the pull wire 4 is guided through a bore and secured with a stop terminal 21 against being pulled out.
  • the end of the wire tension jacket 5 is fastened to the bracket 6 on the horizontal part of the fixed curve 8 close to the bend.
  • the device shown is present on the left door leaf 10.
  • a left and right driver angle are additionally designated as 26 and 27 and indicated by dashed lines as driver device on the shaft door side.
  • the cabin door is coupled to the shaft door (not shown) and the rocker 3 is flipped over by the left driver bracket 26 and the pull wire 4 is pulled to the left by a certain amount.
  • FIGS. 3, 4 and 5 show the same situations as FIGS. 3, 4 and 5 with the difference that the rocker 3 is fastened to the left flank of the fixed curve 8 and has a pressure leg 29 with an angled upper end, that projects to the right over the upper face of the fixed curve 8. Furthermore, the end of the wire pull jacket 5 with the bracket 6 is fastened on the left on the surface of the door leaf 10.
  • the device described above works as follows: A high-quality wire pull jacket with an externally protective-coated spring coil and internal low-friction Teflon coating is used as the wire pull element and a bare and corrosion-protected spring steel wire that glides easily in it is used as the pull wire.
  • the cabin door can be free for manual opening if the rocker 3 by force acting on the pressure leg 23 or. 29 is flipped.
  • the pull wire 4 is pulled out of the pull leg 22 by a certain amount from the wire pull jacket 5 and pulled in at the upper end of the wire pull jacket 5 and pulls the left side of the locking hook 1 with the screw bolt 19 downward against the force of the compression spring 7 and the nose 18 on the right side of the locking hook 1 lifts out from behind the bent stop edge 20 of the hook holder 2, whereby the cabin door, respectively. the door leaves 10 and 11 can be pushed open manually.
  • the car moves with its coupling and driver device with pivoted-in movable curve 9 according to FIGS. 3 and 6 between the driver angles 26 and 27 of the landing door of a landing gear and then swivels the movable curve 9 into the driver position according to FIGS 7.
  • the two variants of the invention differ in that in the first variant according to FIGS. 1, 3, 4 and 5 the rocker 3 on the movable curve 9 and in the second variant according to FIGS. 6, 7 and 8 the rocker 3 on the fixed curve 8 is attached with an angled pressure leg 29.
  • the rocker 3 on the movable curve 9 in the first variant according to FIGS. 1, 3, 4 and 5 the rocker 3 on the movable curve 9 and in the second variant according to FIGS. 6, 7 and 8 the rocker 3 on the fixed curve 8 is attached with an angled pressure leg 29.
  • one or the other variant can be used.
  • any other commercially available means can be used, such as cable pulls of all kinds or flexible push-pull elements with sliding or rolling functionality.
  • the problem could also be solved with an open transmission using a flexible traction means 33 in the form of a string, cord or wire cable, which is deflected, for example, below right next to curves 8 and 9 via a cord roller 34 and is then guided vertically upward to the locking hook 1 .
  • the locking hook 1 must be held in the blocking position by a torsion spring acting in the pivot point 16. This variant of the solution is indicated by dashed lines in FIG.
