Definitions

  • the innovation relates to a door for elevator cars with a multi-part door leaf running between two guides arranged opposite one another on the car, which can be displaced by means of a reversible actuating device.
  • the innovation applies to passenger elevators as well as elevators for loads and goods of all kinds and will be used in particular where the best possible use of the available space is important.
  • the innovation is based on the task of designing a door for cars of elevators so that they open the entire car opening in their open position, that in particular the returning door leaves require very little space and that a car can be easily retrofitted with this door.
  • a known door for cars which has a multi-part door leaf running between two guides arranged opposite one another on the car, which can be displaced by means of a reversible actuating device.
  • the object is achieved in that the door leaf consists of parallel, circular cross-section rods which run with their ends on both sides in the guides and are articulated by at least two rows of connecting links, with two actuators parallel to the rods arranged, set in motion by an electric motor drive rotating shafts are provided which carry two spur gears, the teeth of which engage between the rods.
  • the rods expediently have support rollers at their head ends. With the help of these idlers, the rods can be hung on the upper guide of the door leaf.
  • the rods can carry cylindrical guide rollers at their foot ends, which engage in the lower guide of the door leaf.
  • An upper support rail in the form of a rectangular tube provided with a longitudinal slot and on the other hand a lower guide rail in the form of two parallel hinges serve as guides for the door leaf. These guides are attached to the outside of the car in the area of the door opening of the car and on both sides - corresponding to a "U" in plan - at the level of the roof or the floor.
  • the upper mounting rail and the lower guide rail can be bent into loops to the side of the car. This measure considerably reduces the lateral space required for the returning parts of the door leaves.
  • the upper mounting rail and the lower guide rail can also be wound into spirals on the side next to the car.
  • This embodiment of the guides allows the returning door leaves to be arranged directly to the side of the entrance opening.
  • both the rotary shafts and the electromotive drive can carry chain wheels around which an endless drive chain is wound. This type of actuation can be arranged in a space-saving manner above the upper guide rail or on the roof of the car.
  • An electric geared motor which is reversible with regard to its direction of rotation and which is equipped with a disengaging device is expediently provided as the electric motor drive.
  • This disengaging device enables the door to be opened in an emergency.
  • a simple slip clutch advantageously serves as the disengaging device.
  • profiled support strips are provided between the rods, which have longitudinal channels in which the rods lie. These support strips increase the rigidity of the door leaves considerably, which is particularly advantageous for tall door leaves composed of relatively thin bars, and moreover they effectively prevent the possibility of reaching through between the bars by hand.
  • the support strips expediently have an I-shaped cross section, the height of which corresponds approximately to the diameter of the bars of the door leaves. With this training an almost flat door leaf is achieved.
  • the support strips can either consist of a thermoplastic or thermosetting plastic or can be composed of two identically designed sheet metal profiles.
  • these sheet metal profiles are provided with openings, a measure which enables the attachment of internal welding or soldering points.
  • the door shown in the drawings has two identically designed door leaves 1 and 1 ', which are composed of long, straight rods 2, which are articulated to one another by connecting members 3.
  • Two rotating shafts 4, 4 'arranged next to the rods 2 each carry two spur gears 5, 5', the teeth 6 of which engage in the rods 2.
  • the rods 2 for example composed of steel tubes and of identical design, are arranged in parallel next to one another with a small spacing of about two millimeters, and they have a circular cross section (cf. FIG. 3).
  • the ends 7 of the rods 2 on both sides run in guides which are arranged horizontally opposite one another above and below on the car 8.
  • the connecting links 3 of the rods 2 are arranged in three horizontal rows 9, 10 and 11; the upper row 9 is located near the head ends 12, the lower row 11 near the foot ends 13 of the rods 2 and the third row 10 is located approximately in the middle between the head ends 12 and the foot ends 13.
  • the connecting links 3 are thin, approximately two millimeter thick tabs made of sheet steel, each carrying two holes 14 of the same size. With the help of these bores 14, the connecting members 3 are movably attached to the rods 2, each consisting of two steel tubes. These connecting links 3 permit the rods 2 to be pivoted relative to one another by an angle of approximately thirty degrees.
  • the rods 2 have at their head ends 12 support rollers 15, each of these support rollers 15 is rotatably mounted in a bearing block 16 which is on the top every second link 3 of the upper row 9 is provided.
  • the rods 2 carry cylindrical guide rollers 17 in the form of sleeves made of a suitable plastic, which are coaxially and rotatably seated on the ends 7 of the rods 2 and are held there.
  • the upper mounting rail 18 is a rectangular tube made of steel with a longitudinal slot which is open at the bottom. On both sides, inner shoulders 20 of the mounting rail 18 (see FIG. 4) the paired guide rollers 17 run, and the arrangement is such that the rods 2 of the door leaves 1, 1 'are suspended in the upper mounting rail 18 and in this are easy to move. Guide strips 20 ′ attached to the shoulder 20 laterally guide the ends 7 of the rods 2.
  • the lower guide rail 19 (see FIG. 4) consists of two parallel bands, between which the foot ends 13 of the rods 2, which are reinforced with the guide rollers 17, hang.
  • the upper support rail 18 and the lower guide rail 19 are straight in their middle parts, and they extend horizontally above and below the door opening of the car 8 (FIG. 1).
  • the support rails 18 and the guide rail 19 are bent backwards at right angles in a narrow arc and then bent back into loops 21 which lie close to and outside the inner wall 22 of the car 8.
  • the support rail 18 and the guide rail 19 are bent laterally next to the car 8 (see FIG. 3, right embodiment) to form spirals 23.
  • the loops 21 and the spirals 23 serve the return of the two door leaves 1 and 1 'when the door is open.
  • the two rotary shafts 4 and 4 'are (see. Fig. 3) vertically on both sides of the door opening of the car 8 inside at the point where the support rail 18 and the guide rail 19 extend backwards in an arc and they are in a manner not shown on Car 8 rotatably mounted.
  • the spur gears 5, 5 'of the two rotary shafts 4, 4' sit (Fig. 4) at the height of the mounting rail 18 or the guide rail 19, in the area of which the teeth 6 of the spur gears 5, 5 'from behind into the gap between engage the rods 2 (Fig. 3).
  • each rotary shaft 4 or 4 ' carries a sprocket 25 at its upper end, and the output of the drive 24 also has a sprocket 26, around which an endless drive chain 27 is wound.
  • Two deflection wheels 28 ensure that the (left) rotary shaft 4 is driven in the opposite direction to the (right) rotary shaft 4 '.
  • a slip clutch, a pawl or a magnetic clutch can be provided, which enable the door to be opened in an emergency or in the event of a power failure.
  • profiled support strips 31 - see FIG. 6 - are inserted in the areas between the connecting members 3 and consist either of a thermoplastic or thermosetting plastic or of composite sheet metal profiles.
  • These support strips 31 have an I-shaped cross section, the height 32 of which corresponds to the diameter 33 of the rods 2.
  • the bevelled undersides 34 of the two flanges 35 of the support strips 31 which are triangular in cross section touch (see FIG. 7) the rods 2 on their circumference 36; the rods 2 are in the longitudinal grooves 37 of the support strips 31 formed by the undersides 34.
  • the support strips 31 - as illustrated in FIG. 8 - are composed of two identically designed, multiply bent sheet metal profiles 38: (for example made of sheet steel) so that an I-shaped cross section arises.
  • the two sheet metal profiles 38 have openings 39 on the undersides 34, which allow the attachment of welding or soldering points 40 located inside the sheet metal profiles 38, by means of which the sheet metal profiles 38 are connected to one another.
