Definitions

  • the invention relates to cabin doors for elevators and freight elevators, in particular for transforming smooth-walled elevators.
  • a first difficulty is due to the small width of the shaft which generally does not allow the installation of simple sliding or horizontal telescopic doors used on most modern elevators.
  • Another difficulty stems from the shallow depth of the cabin, which can hardly be further restricted by providing the scanning zones necessary for the operation of the accordion doors.
  • a third difficulty is due to the short distance between the cabin and the smooth wall, which makes it difficult to install telescopic sliding doors with multiple elements and their operator.
  • the object of the invention is to eliminate the above drawbacks, in particular by providing a vertical telescopic door for an elevator car which not only has a small overall width and thickness, but which is also less heavy and less bulky than those known.
  • the invention consists in making a vertical sliding door with three leaves, usually comprising a lower rapid leaf, an upper slow leaf at three times lower speed, and an intermediate leaf at twice the speed of the slow leaf, the three leaves simultaneously retracting upwards in a fixed upper part protruding above the cabin during opening, thanks to an operating and balancing operator.
  • these links can be formed by cables or cables, and the actuation can be carried out using a capstan over which the first link passes.
  • the set of these three main links is preferably doubled by first, second and third auxiliary links with functions identical to that of the respective main links and returned on individual pulleys but to the same counterweight as the main links.
  • the capstan preferably acts only on the first main link, and an electrical contact for detecting mechanical tension of the first auxiliary link is provided so that in the event of the latter breaking, the electric control causes the opening and blocking the door in the open position.
  • the various leaves are preferably constituted by panels with dropped edges directed towards the outside of the cabin, the rapid leaf, the intermediate leaf and the slow leaf succeeding one another and overlapping in order from the outside to the inside. of the cabin, and each carrying in the vicinity of its horizontal ends of the stop tabs on its upper edge to abut on the lower fallen edge, respectively, of the intermediate leaf, the slow leaf and the fixed upper part.
  • the three leaves 1, 2 and 3 are intended, when the cabin is opened, to slide vertically upwards opposite a fixed part 5 protruding above the cabin.
  • the three leaves having identical or substantially identical dimensions, so that their three lower edges arrive at the same time at the lower edge of the fixed part 5, it is therefore necessary that their vertical displacement speeds are respectively in the ratios 1, 2 / 3 and 1/3.
  • the weight of these various panels must be balanced to avoid forceful maneuvering and untimely falling.
  • a first main cable 7 is fixed at 8 to the leaf 1, and after returning to fixed pulleys 9 and 10, it is fixed by its other end at 11 to the counterweight 6.
  • a second cable 12 is fixed at 13 to the second leaf 2 and is returned successively to a fixed pulley 14, a mobile pulley 15, two other fixed pulleys 16 and 17 and a mobile pulley 18, carried by the counterweight 6, before be fixed in 19 on a fixed part.
  • This cable consequently carries out a three-strand haulage on the side of leaf 2, and a two-strand haulage on the side of the counterweight, so that the vertical speed of leaf 2 is, to the nearest sign, 2/3 of speed v the counterweight, that is to say that of the rapid leaf 1, as it should be.
  • a third cable 20 is similarly fixed at 21 to the leaf 3, then, after returning to a fixed pulley 22, a movable pulley 23 carried by the leaf 3, and two other fixed pulleys 24 and 25, it is fixed at its other end at 26 directly on the counterweight 6.
  • the weight of the counterweight 6 must be worth the weight of leaf 1, increased by 2/3 of the weight of leaf 2, and also increased by a third of the weight of leaf 3.
  • the weights of the three leaves being substantially identical, it can therefore be seen that the weight of counterweight 6 is worth substantially twice the weight of a leaf, whereas the usual use of three counterweights each balancing one of the leaves would lead to a total weight of 50% greater, not to mention the increase in size due to the movement of the three counterweights and the connecting devices and dismissal.
  • the operator preferably comprises a simple capstan 27 with a horizontal axis driven by a geared motor 28 visible only in FIG. 7.
  • this drive mode has advantage which if, during the closing operation, the lower edge of the rapid panel 1 encounters an obstacle, this produces a corresponding reduction in the tension of the cable 7 downstream of the capstan 27, and consequently a slippage of the cable 7 on this capstan, automatically stopping the movement of the counterweight, therefore of the three leaves without exerting excessive efforts on the obstacle, which provides a very simple and economical way a definite advantage of safety.
  • the set of the three main cables 7, 12 and 20 above is preferably doubled by three other auxiliary cables of identical design.
  • second auxiliary cable 34 fixed at 35 on the leaf intermediate 2 and returned successively on a fixed pulley 36, on a mobile pulley 37 carried by this leaf, on two other fixed pulleys 38 and 39, then on another mobile pulley 40 carried by the counterweight 6 before being fixed at 41 on a fixed part.
  • a third auxiliary cable 42 is fixed at 43 to the slow leaf 3, and returned to a fixed pulley 44, to a movable pulley 45 carried by the leaf 3, and to two other fixed pulleys 46 and 47 before being fixed at its other end at 48 on the counterweight 6.
  • an electrical contactor 49 visible in FIG. 2, is provided to detect the voltage of the first auxiliary cable 29 so that, in the event of this cable breaking, the electrical control causes the door to open if it does not exist. is not already open, and the blocking of this door in the open position.
  • the various fixed pulleys can advantageously be grouped and stepped on four axes, including the axis 50 which groups the three pulleys 31, 36 and 44, the axis 51 which groups the four pulleys 16, 38, 24 and 46, the axis 52 which groups the three pulleys 9, 14 and 22, and finally the axis 53 which groups the six pulleys 10, 32, 17, 39, 25 and 47.
  • the counterweight 6 is located immediately to the right of the opening. It would naturally be just as easy to place it at left by a completely symmetrical arrangement, or else to place it in any other available available location, with additional references if necessary.
  • the three leaves 1, 2 and 3 are advantageously formed, in the usual way, using sheet metal panels with fallen edges oriented towards the outside of the cabin and internally reinforced by stiffening pieces 54, visible only on Figure 2. At their upper part and in the vicinity of the center, they are also provided with reinforcing parts 55, carrying respectively the fixing and tensioning parts 8, 30 for the rapid leaf 1, the fixing and tensioning parts 13 and 35, as well as the axes of the pulleys 15 and 37 for the intermediate leaf 2, and finally the fixing and tensioning parts 21 and 43, as well as the axes of the pulleys 23 and 45 for the slow leaf 3.
  • the entire structure integral with the cabin constitutes a frame with an upper cross member 56, carrying the fixed pulleys and the capstan 27 with its motor 28, a lower threshold cross member 57 , preferably constituted by the existing cabin floor, and two vertical uprights 58 affecting the shape of two U-shaped nests and welded as shown in Figure 3, so as to form therebetween three grooves 59, 60 and 61 extending from the top below, and in which the three leaves 1, 2 and 3 respectively slide, preferably by means of rollers 62 with a horizontal axis perpendicular to the plane of the leaves, and rollers 63 with a horizontal axis parallel to the plane of the leaves.
  • the upright 58 is doubled by a rail 65 ensuring the guiding of the counterweight by means of sliding linings 66 as shown in FIG. 3.
  • stop tabs 67 intended to abut on the lower fallen edge of the immediately upper leaf, or of the fixed panel 5 for the leaf slow 3, these tabs passing on each side in the free vertical passage 68 formed between the roller support plates 64 and the ends of the stiffening pieces 54. In this way, none of the three leaves 1, 2 and 3 can fall completely up to threshold 57, except in the event of complete breakage of the six cables, which is practically impossible.
  • the door according to the invention is therefore extremely simple, space-saving and not heavy, and also has absolute operating safety, which makes it possible to use it both for load elevators and for passenger elevators.
