As shown in FIG. 1 , a door device frame 2 is fixed above a car doorway 1 .

A door guide rail 3 extending along the front width direction of the car doorway 1 is fixed to the door device frame body 2 .

The pair of door main bodies 4 are displaced in the horizontal direction under the guidance of the door rails 3 to open and close the car doorway 1 .

A pair of door main bodies 4 are configured to respectively have a door panel 5, a door hanger 6 fixed on the upper end of the door panel 5, and a plurality of hanger rollers 7. The hanger rollers 7 are arranged on the door hanger 6 and can be moved along the door. Rail 3 rolls.

The door main body 4 is opened and closed by the driving force of the door motor attached to the door apparatus.

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 reinforcement member (not shown) fixed to the lower portion of the back surface of the door panel 5 .

In addition, a car sill 9 extending along the front width direction of the car doorway 1 is fixed to the floor portion of the car doorway 1, and a door for guiding the opening and closing of the lower end of each door body 4 is provided on the car sill 9. In the sill groove 9a, the door foot 23 is inserted into the sill groove 9a.

A lower shield 19 capable of moving up and down is provided at the lower end of the door body 4 to seal the gap between the lower end of the door body 4 and the car sill 9 when the door is closed. The lower shielding body 19 has a movable plate 20 and a seal member 21 fixed to the lower end of the movable plate 20 so as to be in contact with or separated from the car sill 9 .

The seal member 21 is made of, for example, an elastic body such as rubber or resin, extends over the entire width direction of the door body 4, and contacts or separates from the upper surface of the car sill 9 at a portion closer to the elevator car side than the sill groove 9a. .

The operation will be described below.

When the door is in the closed state, the pressing parts 10 of the left and right doors press each other under the action of closing the door, so that the bar 11 mounted on the pressing part 10 moves horizontally in the frontal width direction through the sliding mechanism 12 .

Along with the horizontal movement of this rod 11, the rod 13 rotates counterclockwise around the center of rotation 13a. to the left of the ) to move.

Thereafter, as the rod 14 moves, the rod 15 rotates clockwise around the rotation center 15 a, and the rod 16 connected to the rod 15 descends.

As the rod 16 descends, the movable plate 20 connected with the rod 16 descends along the sliding mechanism 22, and as the movable plate 20 descends, the sealing member 21 fixed on the movable plate 20 descends thereupon and is pressed On the car sill 9.

Here, the gap between the lower end portion of the door body 4 and the car sill 9 is sealed by pressing the sealing member 21 against the car sill 9 .

Further, as the rod 16 descends, the rod 17 connected to the rod 16 rotates counterclockwise around the rotation center 17 a, and the counterweight 18 connected to the rod 17 rises as the rod 17 rotates.

When the door body 4 starts to open the door in this door-closed state, the pressing portion 10 in the pressed state changes from the pressed state to the non-pressed state.

As a result, the rod 17 descends under the weight of the counterweight 18 and rotates clockwise around the rotation center 17 a. As the rod 17 rotates, the rod 16 connected to the rod 17 rises.

As the rod 16 rises, the movable plate 20 connected to the rod 16 rises, and as the movable plate 20 rises, the sealing member 21 fixed to the movable plate 20 rises.

In addition, as mentioned above, the linkage mechanism 8 in the present invention is a linkage mechanism that moves the lower shielding body 19 up and down. When the door is in the closed state, the linkage mechanism 8 lowers the lower shielding body 19, and when the door is in the open state, the linkage mechanism The mechanism 8 keeps the lower shielding body 19 away from the car sill 9 . Specifically, the linkage mechanism 8 is configured to have a bar 11 that moves horizontally with the displacement of the pressing member 10, a slide mechanism 12 that guides the horizontal movement of the bar 11, and a center of rotation 13a along with the horizontal movement of the bar 11. A rod 13 that rotates counterclockwise around the center, a rod 14 that moves toward the car entrance 1 (left side in FIG. The center 15a is a rod 15 that rotates clockwise around the center, a rod 16 that descends with the rotation of the rod 15 and makes the lower shielding body 19 contact the car sill 9, and a rod 17. 16 descends and rotates counterclockwise around the rotation center 17a, so that the counterweight 18 connected thereto rises.

As described above, according to the car door device of the present invention, the lower shielding body 19 can be moved up and down by the movement of the pressing part 10 and the up and down movement of the counterweight 18, so that the opening and closing performance of the door main body 4 can be maintained. , the gap between the lower end portion of the door main body 4 and the car sill 9 is further reliably sealed in the door closed state.

Therefore, airtightness, smoke barrier properties, sound insulation properties, and light shielding properties can be improved.

In addition, since the pressing part 10 operates only when the door main body 4 is within a predetermined range from the fully closed position, and is located in the car sill groove 9a, the lower shielding body 19 can be moved relative to the movement of the door main body 4. Actions are suppressed to a smaller extent.

When the lower shielding body 19 is raised and lowered, it is not necessary to use a dedicated drive source such as a motor, so the cost can be reduced.

And, since the lower shielding body 19 is raised and lowered in the vertical direction, the lower shielding body 19 can be set on the entire width direction of the door main body 4, and the lower shielding body 19 can be prevented from moving from the end of the width direction of the door body 4 along with its displacement. Ministry protruding.

As mentioned above, by arranging the pressing part 10 in the sill groove 9a where the passengers cannot see, and setting the linkage mechanism 8, the lower shielding body 19 and the counterweight 18 in the door body where the passengers cannot see 4, the decorative effect can be avoided, and the gap between the lower end of the door main body 4 and the car sill 9 can be sealed when the door is closed.

In addition, since the sealing member 21 is formed of an elastic body, manufacturing errors and installation errors can be absorbed by the elastic deformation of the elastic body, and the sealing member 21 can be brought into close contact with the car sill 9 .

In addition, by providing the rod 16 not only movable in the vertical direction but also movable in the rotational direction, when an error occurs in the gap between the lower end of the door main body 4 and the car sill 9, the lower part can be covered. The lifting stroke of body 19 can be fine-tuned, and the adjustment work during fine-tuning can be carried out conveniently.

And, since the lifting area of the counterweight 18 can be arranged on the inner side of the door panel 5, and the lower shielding body 19 and the linkage mechanism 8 can be arranged near the lower end of the door panel 5, it is possible to realize miniaturization as a whole, and also It can be easily applied to products in which a cover is provided on the door panel 5 and products in which a reinforcing member is fixed to the door panel 5 .

second embodiment

Fig. 5 is an enlarged view showing a main part of an elevator car door device according to a second embodiment of the present invention.

When the door is in the closed state, the pressing parts 10 of the left and right doors press each other under the action of closing the door, and the rod 24 mounted on the pressing part 10 rotates counterclockwise around the rotation center 24a.

As the rod 24 rotates, the rod 14 connected to the rod 24 moves in the direction of the car doorway 1 . Other structures are the same as the first embodiment.

As described above, by providing the interlocking mechanism 8 in a structure that does not use a sliding mechanism, it is possible to reduce the weight of the car door and reduce the cost of materials.

Since the rotational movement of the rod 24 does not require high precision like the horizontal movement, the influence of manufacturing errors and installation errors can be reduced.
