Definitions

  • the invention relates to a folding door, in particular for elevators, of the type comprising at least one pair of hinged connected leaves, one after the other by means of articulation elements forming a hinge part provided on the sides.
  • longitudinal of each leaf each leaf having a central part and two wings respectively disposed on either side of the central part and oriented in the same direction, and the second leaf of the pair or of each pair of leaves of the deployed door in the closed position being rotated 180 ° around its longitudinal axis and 180 ° around its median axis relative to the first leaf.
  • folding doors are that they can be zigzagged. Therefore, during the opening operation, they require neither a rectilinear removal of the leaves laterally to the door bay nor a curvilinear withdrawal followed by a rectilinear withdrawal of the leaves for an arrangement perpendicular to the bay of the door.
  • each leaf has, in profile, a flat central part provided on one side and on the other with a curved lateral wing for strengthening the rigidity, the two wings being oriented in the same direction.
  • Separate leaf hinge elements forming complementary hinge parts are provided at certain locations along the height of the leaf. These articulation elements are carried by plates fixed alternately to one and the other sides of the leaf. They are respectively arranged at the ends of the wings, in such a way that one of the elements is placed higher than the other relative to the central part and is hidden by the also higher end of the wing concerned.
  • the present invention aims to remedy the drawbacks of this known construction.
  • it makes it possible to provide a solution to the problem which consists in creating a folding door of the type mentioned at the beginning, in particular a door for elevators, the leaves of which can both have a good rigidity and occupy a minimum of space when the door is folded in the open position.
  • a folding door having the aforementioned characteristics can be constructed from a single type of leaf of relatively simple manufacture whose particular profile, on the one hand, ensures the leaf excellent rigidity and, on the other hand, allows the leaves to be nestable during the opening operation, which significantly reduces the space occupied by the leaves. Therefore, a folding door construction in a single foldable part on one side of the door opening or in two foldable parts on both sides of the door and provided with two or more pairs of leaves for each part can easily to be considered.
  • the reference 1 designates, shown in plan view, one of the leaves 1A, 1B, 1C, 1 D of a folding elevator door with two pairs of leaves shown in the folded position in FIG. 2.
  • the references 2 and 3 designate articulation elements of tubular shape respectively disposed on the two longitudinal sides of the leaf 1.
  • the articulation elements 2 provided on one side of the leaf 1 are complementary to the articulation elements 3 provided on the other side and thus constitute hinge parts in which can be engaged cylindrical rods 4 forming axes d 'joint.
  • FIG. 3 which partially shows, from the front and deployed, two of the leaves 1A, 1B hinged together from the folding door shown in FIG. 2.
  • the reference XX ' represents for the leaf 1 an axis of symmetry which extends perpendicular to a line designated by YY' passing through the axes of the opposite articulation elements 2 and 3 provided on the two longitudinal sides of the leaf 1.
  • the reference 5 designates a central part of the leaf 1 which, in profile, consists of a rectilinear core disposed along the axis of symmetry XX 'and extending parallel to the line YY' passing through the axes of the articulation elements 2 and 3, l 'one of its faces being practically placed in the plane of the line YY'.
  • the leaf 1 comprises in profile a wing 6, 7 which connects the central part 5 to the respective articulation elements 2, 3.
  • Each wing 6, 7 consists of two branches 6.1, 6.2; 7.1, 7.2 forming between them an angle greater than 90 ° which, for each wing 6, 7, is of the same size and is oriented in the same direction.
  • the branch 6.1, 7.1 adjacent to the central part 5 is of the same length and, from the central part 5, it departs from the axis of symmetry XX ', the angle y formed by l 'one of the branches 6.1 relative to the axis of symmetry XX' being greater than the angle 5 formed by the other branch 7.1.
  • the leaf 1, preferably metallic, thus constitutes a profiled element which has good rigidity and has a certain asymmetry with respect to the axis XX '.
  • the central part 5 of the leaf 1 and its two lateral wings 6 and 7 can be, for example, obtained by pressing and the articulation elements 2 and 3 can be added by welding, but the complete leaf 1 can also be obtained from 'other manufacturing techniques such as profiling, arec a particular machining for complementary articulation elements 2 and 3, or by pressure molding.
  • the folding elevator door shown in the folded position in FIG. 2, comprises two pairs of leaves 1 of the type shown in FIG. 1.
  • the reference 8 indicates, diagrammatically, one of the uprights of an elevator car to which the first leaf 1A of the four leaves 1A, 1B, 1C, 1D constituting the folding door is articulated by means of one of the cylindrical rods 4 forming an axis of articulation.
  • the four leaves 1A, 1B, 1C, 1D are connected hinged one after the other also by means of cylindrical rods 4.
  • the door is folded during the opening operation and deployed during the operation closing by translational movements carried out perpendicular to the amount 8 of the cabin, in the direction of the arrows F and F 'respectively.
  • the door can, for example, be suspended from a guide rail arranged at the upper part of the cabin by means of rollers mounted on an extension of the last two cylindrical rods 4.
  • the same cylindrical rods 4 can be provided with rollers circulating in a guide rail disposed in the floor of the cabin.
  • rollers which, like the door drive device, are well known in the elevator technique for suspending, guiding and driving landing doors and / or cabins have not been shown.
  • a type of suspension and guide for a folding door of this kind is shown, for example, in French patent No. 1,025,073.
  • Figure 2 shows that, during the assembly of the joints which allow the leaves 1 to extend one after the other once the folding door deployed in the closed position, the second leaf 1B, 1D of each pair leaves was firstly rotated 180 ° about its longitudinal axis and, secondly, rotated 180 ° around its axis of symmetry XX 'relative to the first leaf 1A, 1C. From a single model of leaf 1, it is thus possible to provide a folding door whose leaves can have a rigidity which is close to that of the boxes and fit into one another, so that all the leaves occupy a minimum space once the door is folded into the open position.
  • the leaf 1 whose profile, in particular of the central part, could have other shapes than those shown, the condition being that the central part is arranged along the axis of symmetry XX 'of the leaf and that a certain asymmetry exists between the two wings connecting the central part to the articulation elements.
  • the branches of the wings adjacent to the central part could be provided so as to be connected on the axis of symmetry. In this case, the central part would merge with the axis of symmetry.
