Definitions

  • the present invention relates to a telescopic elevator door assembly.
  • the door lintel on which the tracks have to be fastened must have flat support points to form exact reference points for the tracks, in at least three points. Also, it is necessary to use separators to fasten and install the two tracks in their position.
  • the present invention aims to overcome the above problems by providing a telescopic elevator door assembly in which both the high and low speed doors are mounted on a single common track, the doors sliding along said track by means of roller assemblies, characterised in that said roller assemblies each comprise a housing connected to one of said doors and rolling means mounted within and surrounded by said housing, said track extending through said housing, and said rolling means running on said track.
  • the rolling means are mounted in the housing, they are protected from dirt and dust, and are also held in a set position so that when the whole assembly is connected to a door the rolling means automatically take up their correct position which means that no adjustments are required.
  • a sub-assembly can be formed of the roller assemblies and track, which can be placed in the door lintel without the need for complicated alignment procedures.
  • the rolling assembly can have many different embodiments compatible with the type of track chosen, each of which provide stiff shafts or supports for rolling elements of the rolling means.
  • the rolling elements themselves may comprise a roller and counterroller mounted in said housing and having guide flanges which engage the track over which they roll or slide.
  • the housing may be formed by two cups facing each other and fastened to one another by means of transversal pins, which may be threaded and may not only form the fastening means of both cups, but also the fastening means of the device to the hanger support of the door, as well as the axles for the rolling elements themselves which roll along the track.
  • the rolling elements could consist of a non-flanged roller guided and supported at the top on the track, a bottom counterroller, and a set of side rollers, or even convex contact surfaces running along both sides of the track.
  • Another alternative rolling element for use with a track of circular cross-section consists of a set of linear ball bearings mounted circumferentially around the track.
  • high and low speed doors 1 and 2 are connected to a corresponding hauling cable 3 from which a counterweight 4 hangs.
  • the sliding track of both doors 1 and 2 is made up of a single common element 5, which may have different forms as far as its cross-section is concerned.
  • the rolling elements of both the high-speed panel 2 and low-speed panel 1 slide over this track 5.
  • the hanging support 6 of the slow-speed panel or door 2 is longer than the hanging support 7 of the high-speed panel or door 1, making it possible to leave a free area in the central part of the track 5 to situate said hanging support 7 therein.
  • the two high speed rolling elements are positioned on the track between the two low speed door rolling elements.
  • the distance D between the two right-hand rolling elements must be longer than half the total opening width of the door.
  • the rolling unit itself may use linear ball bearings 8 for a circular section track 5' shown in Figure 4, while for a rectangular section track 5 further constructions as shown in Figures 2, 3 and 5, can be used.
  • the rectangular section track 5 is specifically shown in Figure 2, as well as the corresponding hanger support 7 of the door.
  • the rolling unit is made up of a housing formed by two halves or cups 9 facing each other, inside of which are a top roller 10 that rests on the longitudinal top edge of the track 5 and a bottom counterroller 11 which lies below the longitudinal bottom edge of the track 5.
  • a top roller 10 that rests on the longitudinal top edge of the track 5
  • a bottom counterroller 11 which lies below the longitudinal bottom edge of the track 5.
  • roller and counteroller are held in position by the housing and so there is no need to make any adjustments to them when the housing is attached to the door as they will automatically be in their correct alignment.
  • the two cups or halves 9 which form the housing of the rolling unit remain fastened to each other by screws 12 which, aside from being the fastening means of the roller 10 and counterroller 11, form the fastening means of the rolling unit to the hanger support 7.
  • FIG. 3 An alternative embodiment of the rolling unit is shown in Figure 3, where the case is again formed by opposing semi-enveloping cases or cups 9′ fastened together, and to the hanger support 7, by means of screws 12′.
  • the profiled rollers have been replaced by side friction rollers or wheels 13, which collaborate in the guiding of the non-profiled roller 10′ in its sliding over the top edge of the track 5.
  • the housing may have additional protection for fireproof doors without complicating the structure of the unit.
  • the rolling elements may be made up of linear ball bearings 8 protected by a case 9 ⁇ which likewise fastens to the hanger support 7 by means of corresponding screws 12 ⁇ .
