Definitions

  • the invention relates to a door construction for an elevator, namely for a door of an elevator car or for a door of a hoistway according to the preamble of claim 1.
  • Normally two groups of door segments are provided: the segments of each group open telescopically and always move together in the same direction.
  • the door segments of one group move from the center to the left when opening, and the others move from the center to the right, see for example WO 2004/050529-A1 , Often it is necessary for reasons of space, the door segments of a group of different width to form the door segments of the other group.
  • Lifts must meet strict safety criteria.
  • One of them is that the middle door segments can not be impressed significantly when a certain force is applied. This is a problem with narrow door segments because they are only on top and the test must be performed even when the force is applied below.
  • there is a lever whose longer lever arm is given by the height of the door and whose shorter lever arm is given by the width of the door segment - more precisely, by the distance of the rollers, which is slightly smaller than the width of the door segment. (If sliding elements are provided instead of rollers, then the distance between the outermost points of the sliding elements is decisive.) It is clear that with narrow door segments such a high leverage results that the demands on the guide are extremely high and only by disproportionately high technical Effort can be met.
  • the aim of the invention is to avoid this disadvantage and to propose a door hanger of the type mentioned, in which the leadership of the narrow door segments is improved.
  • the width of the door segments of the two groups is different, driving the two groups can be difficult because the two groups must be driven at different speeds if the door segments of the two groups are to open at the same time.
  • the door segments are coupled with each other in a motion-locking manner, so that only one door segment (usually the fastest) has to be driven.
  • the two groups of door segments are driven by a common drive via a stepped disc.
  • Fig. 1 schematically an axonometric view of the suspensions of door segments according to the invention
  • Fig. 2 schematically a view of the suspensions after
  • the invention will be explained with reference to an elevator car door, but it can also be applied to an elevator shaft door.
  • There are two groups of door segments one group containing the two left (as in Fig. 2 seen) segments 20 and 21 and the other group the two right (as in Fig. 2 seen) segments 20 ', 21' comprises.
  • the segments 20, 21 of one group open to the left (as in FIG Fig. 2 seen), the segments 20 ', 21' of the other group open to the right (as in Fig. 2 seen).
  • the two door segments 20, 21 and 20 ', 21' slide telescopically when opening.
  • the right door segments 20 ', 21' are narrower than the left door segments 20, 21.
  • two rails 2, 2 ' are fixed on a support 1, which is mounted on an elevator car, not shown.
  • the rails 2, 2 'of bolt 3 which also determine a distance between the carrier 1 and the rail 2 and thus a gap 4.
  • the gap 5 between the two rails 2, 2 ' is also determined by the bolt 3.
  • suspensions 6, 6 ' which are connected to (edge-side) door segments 20, 20' and hold them.
  • the door segments 20, 20 'and the corresponding suspensions 6, 6' have different widths.
  • rollers 7 held on the top and Unroll underside of rail 2.
  • the upper rollers are referred to as trailer rollers because the respective door segment hangs on them.
  • the lower rollers are called counter-rollers, these prevent lifting of the door segments. Instead of rollers 7 and sliding elements can be used.
  • the gap 5 between the two rails 2, 2 ' is penetrated by suspensions 8, 8' which are connected to (middle) door segments 21, 21 'and hold them.
  • suspensions 8, 8 ' On the suspensions 8, 8 ', four rollers 7 are also held, which roll on the rail 2'.
  • 9 are arranged on the suspensions 6, 6 ', 8, 8', which cooperate with runners 10 and together form a coupler for the shaft door, but are not part of the invention. Through this coupler, the shaft door is taken when the car door opens, so that the shaft doors do not need their own drive.
  • the shaft door is provided with a lock that prevents it from opening when the cab is not behind the shaft door. This locking is not part of the invention.
  • the suspension 8 ' which is provided for a narrower door segment 21', a projection 11, in the region of two rollers 7 are arranged.
  • the drive of the two door segments 20, 21 and 20 ', 21'jeder group is normally carried out so that the middle door segment 21, 21' is actively driven and the edge-side door segment 20, 20 'via a reduction in the ratio 2: 1 from the middle Door segment 21, 21 'is taken.
  • the two middle door segments 21, 21 '- should the opening movement in both groups take the same length - of course not be driven at the same speed. If the width behaves as 1: 2, the narrower middle door segment 21 'could be driven by the wider edge door segment 20. However, this would require additional space, which according to the invention should just be saved.
  • a drive motor 13 which is a gear in the form of a stepped pulley 14 (see Fig. 2 ) drives.
  • the stepped disc 14 can be designed as a stepped pulley, which by means of two belts 15, 16 which are guided over deflecting plates 17, the central door segments 21, 21 'via the suspensions 8, 8', which are connected to the belts 15, 16 are, drives.
  • the suspensions 8, 8 ' are moved and z. B. via a common carrier, not shown, z. B. in the form of a rope, the suspensions 6 ', 6 taken.
  • Such a drive is usually necessary only at the car door.
  • the shaft door is moved by the movement of the car door is transmitted via a coupler on the shaft door.
