  • an interlocking mechanism for moving the lower shield up and down.
  • the pressing portion at a position that cannot be seen by the passenger, it is possible to seal the gap between the car door lower end and the car sill when the door is closed without impairing the design.
  • the gap between the lower end of the door body and the car sill can be compactly sealed within the vicinity of the lower end of the door.
  • FIG. 3 is a cross-sectional view taken along aa in FIG. 2.
  • FIG. 3 is a cross-sectional view taken along line bb of FIG. It is an enlarged view which shows the principal part of the elevator car door apparatus by Embodiment 2 of this invention.
  • FIG. 1 is a rear view (viewed from a hoistway side) showing an elevator car door device according to Embodiment 1 of the present invention
  • FIG. 2 is an enlarged view showing a main part of FIG. 1
  • FIG. 3 is a line aa.
  • FIG. 4 is a sectional view taken along the line bb.
  • a door device housing 2 is fixed above the car doorway 1.
  • a door rail 3 is fixed to the door device casing 2 so as to extend along the entrance direction of the car doorway 1.
  • the car doorway 1 is opened and closed by a pair of door main bodies 4 being guided by the door rails 3 and being displaced in the horizontal direction.
  • Each of the pair of door bodies 4 includes a door panel 5, a door hanger 6 fixed to the upper end portion of the door panel 5, and a plurality of hanger rollers 7 provided on the door hanger 6 and rolled along the door rail 3. It is configured.
  • the door body 4 is opened and closed by the driving force of a door motor mounted on the door device.
  • a plurality of door legs 23 are attached to the lower end of each door body 4, and the door legs 23 are fixed to a reinforcing member (not shown) fixed to the lower back of the door panel 5. .
  • a car sill 9 extending along the frontage direction of the car doorway 1 is fixed to the floor of the car doorway 1.
  • a door leg 23 is inserted into the car sill 9 so that each door main body is inserted.
  • 4 is provided with a threshold groove 9a for guiding opening and closing of the lower end portion.
  • a lower shield 19 that seals the gap between the lower end of the door body 4 and the car sill 9 when the door is closed is provided at the lower end of the door body 4 so as to be movable up and down.
  • the lower shield 19 includes a movable plate 20 and a seal member 21 that is fixed to the lower end portion of the movable plate 20 and contacts and separates from the car sill 9.
  • the seal member 21 is made of, for example, an elastic body such as rubber or resin, and extends over the entire width direction of the door body 4, and comes in contact with and separates from the upper surface of the car sill 9 on the car side with respect to the sill groove 9 a.
  • the horizontal movement of the bar 11 causes the lever 13 to rotate counterclockwise around the rotation center 13a, and the rotation of the lever 13 causes the bar 14 connected to the lever 13 to move toward the car entrance 1 (left side in FIG. 2). )
  • the lever 17 is rotated clockwise around the rotation center 17 a by the lowering of the counterweight 18 due to its own weight, and the bar 16 connected to the lever 17 is raised by the rotation of the lever 17.
  • the interlocking mechanism 8 lowers the lower shield 19 when the door is closed, and the lower shield 19 is separated from the car sill 9 when the door is open.
  • This is an interlocking mechanism that moves the lower shield 19 up and down.
  • the bar 11 moves horizontally according to the displacement of the pressing member 10, the slide mechanism 12 that guides the horizontal movement of the bar 11, and the bar 11.
  • a lever 13 that rotates counterclockwise around the rotation center 13a according to the horizontal movement of the bar, a bar 14 that moves in the direction of the car doorway 1 (left side in FIG.
  • the lower shield 19 can be moved up and down by using the movement of the pressing portion 10 and the vertical movement of the counterweight 18. While maintaining the door, the gap between the lower end of the door body 4 and the car sill 9 can be reliably sealed when the door is closed.
  • the pressing portion 10 operates only when the door body 4 is within a predetermined range from the fully closed position, and is located in the car sill groove 9a. The operation can be kept small.
  • the lower shield 19 since the lower shield 19 is lifted and lowered in the vertical direction, the lower shield 19 can be provided over the entire width direction of the door body 4, and the lower shield 19 is moved along with the displacement of the door body 4. It can prevent protruding from the width direction edge part.
  • the pressing portion 10 is provided in the sill groove 9a that is not visible to the passenger, and the interlocking mechanism 8, the lower shield 19, and the counterweight 18 are provided inside the door body 4 that is also invisible to the passenger.
  • seal member 21 is made of an elastic body, manufacturing errors and installation errors can be absorbed by elastic deformation of the elastic body, and the seal member 21 can be brought into close contact with the car sill 9.
  • the bar 16 is movable not only in the vertical direction but also in the rotational direction, the vertical stroke of the lower shield 19 can be finely adjusted with respect to the variation in the gap between the lower end of the door body 4 and the car sill 9. And the adjustment work is easy.
