  • the connecting ropes 11 and the connecting rope guide rollers 13a to 13c are disposed such that the door main bodies 3 are forced in a door closing direction by the weights 10.
  • the door main bodies 3 When a door opening operation is started, the door main bodies 3 are moved in a door opening direction against the force from the weights 10 on the door main bodies 3. Thus, the pivoting levers 9 are pivoted in such a direction that the first connecting portion 9a and the weights 10 are displaced upward.
  • the movable covering bodies 14 are raised and separated from the landing doorsill 7 by the pivoting of the pivoting levers 9.
  • the movable covering bodies 14 gradually descend, and the covering members 16 come into contact with the landing doorsill 7 at the time of completion of the door closing operation. Consequently, the movable covering bodies 14 do not slide on the landing doorsill 7 during the opening and closing operations, preventing abrasion of the covering members 16 and the occurrence of noise.
  • a landing door apparatus of this kind because the movable covering bodies 14 are made to be placed in contact with the landing doorsill 7 in a door closed state, and the movable covering bodies 14 do not come into contact with the landing doorsill 7 during opening and closing operations, gaps at lower end portions of the door main bodies 3 can be covered in the door closed state while maintaining opening and closing operation performance of the door main bodies 3. Thus, smoke insulation and sound insulation can be improved.
  • the connecting ropes 11 are connected between the pivoting levers 9 and the door apparatus housing 1 to pivot the pivoting levers 9 together with the opening and closing of the door main bodies 3, and the movable covering bodies 14 are made to be placed in contact with and separated from the landing doorsill 7 by this pivoting of the pivoting levers 9, the construction can be simplified, and mounting and adjustment can be facilitated.
  • the movable covering bodies 14 are placed separably in contact with the landing doorsill 7 on a landing side of a doorsill groove 7a, smoke can be prevented from penetrating inside a panel of the door main bodies 3, and smoke can also be prevented from passing through the panel, and penetrating into the hoistway. Furthermore, damage to the covering members 16 can be checked easily from the landing side, also enabling workability during maintenance to be improved.
  • connecting rope guide rollers 13a to 13c for directing the connecting ropes 11 toward the pivoting levers 9 are disposed on the door hangers 4 and the door main bodies 3, the connecting ropes 11 can easily be prevented from interfering with the other machinery.
  • the stroke of the movable covering bodies 14 can be made smaller than the opening and closing stroke of the door main bodies 3, enabling space occupied by the movable covering bodies 14 to be reduced.
  • connecting ropes 11 are disposed such that the door main bodies 3 are forced in a door closing direction by the weights 10, it is no longer necessary for a means for forcing the door main bodies 3 in the door closing direction to be disposed separately, enabling the construction to be simplified.
  • the construction is simple, and a stable force can be generated irrespective of the position of the door main bodies 3.
  • Figure 7 is a rear elevation showing a door open state of an elevator landing door apparatus according to Embodiment 2 of the present invention.
  • a pivoting lever 31 functioning as a pivoting member that is pivotable around a pivoting shaft 30 is mounted to a back surface of each of door main bodies 3.
  • the pivoting levers 31 are pivoted together with opening and closing operations of the door main bodies 3.
  • the pivoting levers 31 have first and second connecting portions 31a and 31b.
  • the first and second connecting portions 31a and 31b are disposed on the same side of a pivoting shaft 30 as each other. A distance from the pivoting shaft 30 to the first connecting portion 31a is greater than a distance from the pivoting shaft 30 to the second connecting portion 31b.
  • a connecting rope 11 is connected between the first connecting portion 31a and a central portion of a door apparatus housing 1 in a direction of frontage.
  • Short ropes 21 are connected between the second connecting portions 31b and the hooks 18.
  • a plurality of rotatable short rope guide rollers 32a and 32b for directing the short ropes 21 from the second connecting portions 31b to the hooks 18 are disposed on the back surfaces of the door main bodies 3.
  • Weights 10 functioning as a forcing means for forcing the pivoting levers 9 in such a direction that the movable covering bodies 14 come into contact with the landing doorsill 7 are mounted to end portions of the pivoting levers 31 near the first connecting portions 31a.
  • the connecting ropes 11 are disposed such that the door main bodies 3 are forced in a door closing direction by the weights 10.
  • the rest of the construction is similar to that of Embodiment 1.
  • first and second connecting portions 31a, 31b are disposed on the same side of the pivoting shaft 30 in this manner, similar effects to those in Embodiment 1 can also be achieved.
  • weights 10 are used for the forcing means, but the forcing means is not limited to weights, and a torsion spring, etc., can also be used, for example.
  • a spring for pressing a movable covering body against a doorsill may also be disposed between a door main body and a movable covering body as a forcing means.
  • weights may also be mounted to a movable covering body.
  • use may also be made of the deadweight of a movable covering body to make the movable covering body function as a weight.
  • Figure 8 is a rear elevation showing a door closed state of an elevator landing door apparatus according to Embodiment 3 of the present invention
  • Figure 9 is a rear elevation showing a door open state of the landing door apparatus in Figure 8 .
  • connecting ropes 11 were connected to a central portion in a direction of frontage of the door apparatus housing. 1, but in Embodiment 3, connecting ropes 11 are connected to end portions in the direction of frontage of the door apparatus housing 1. For this reason, door main bodies 3 are forced in a door opening direction due to gravity acting on weights 10. However, since the door main bodies 3 are locked in a door closed position in a door closed state, the door main bodies 3 will not perform a door opening operation automatically unless the lock is released.
  • Embodiment 1 since directions of operation of the second connecting portions 9b and directions of operation of the movable covering bodies 14 were in opposite directions, direction-changing rollers 22 were used, but In Embodiment 3, since the directions of operation of the second connecting portions 9b and the movable covering bodies 14 are the same, direction-changing rollers are unnecessary. The rest of the construction is similar to that of Embodiment 1.
  • the connecting ropes 11 are connected between the pivoting levers 9 and the door apparatus housing 1 to pivot the pivoting levers 9 together with the opening and closing of the door main bodies 3, and the movable covering bodies 14 are made to be placed in contact with and separated from the landing doorsill 7 by this pivoting of the pivoting levers 9, the construction can be simplified, and mounting and adjustment can be facilitated.
  • Embodiments 1 to 3 a pivoting lever and a movable covering body were connected by a short rope, but it is also possible to make the connection by a link member, for example.
  • Embodiments 1 to 3 landing door apparatuses were explained, but the present invention can also be applied to car door apparatuses, enabling sound insulation and smoke insulation to be improved. In that case, it is preferable for a movable covering body to come into contact with a floor portion on a cab interior portion side of a doorsill groove of the car.
  • the present invention can be applied to centrally-opening door apparatuses and to side-opening door apparatuses, and can also be applied to single panel door apparatuses and door apparatus having a plurality of panels.
