Description

  The present invention relates to an elevator apparatus, and more particularly to an elevator apparatus suitable for a building in which a seismic isolation device is installed in the middle.

As this type of conventional technology, two columns are mounted on the base isolation floor and the upper layer, and the upper and lower ends are rotatably mounted and arranged in equilibrium in the vertical direction. The horizontal beams are arranged in a balanced manner in the horizontal direction, and the upper and lower horizontal beams are configured to enter and exit from the elevator in relation to the inclination of the column. When the seismic isolation floor and upper floors are attached to the horizontal beam, and the seismic isolation floor and the upper floor are displaced in the front-rear and lateral directions, the car floor and the floor door contact or space Is prevented from spreading too much, and the engagement device for opening and closing the door is prevented from being damaged (see, for example, Patent Document 1).
Japanese Patent No. 3331520 (paragraph number 0005, FIG. 1)

  However, in the above-described conventional type, when a lateral movement occurs between the base isolation floor and the upper floor due to an earthquake, the column tilts in accordance with this movement, and the upper and lower units attached to the column freely rotate. The horizontal beam slides and moves in the horizontal direction, and a substantially rectangular shape is formed by the two columns and the upper and lower horizontal beams. However, at this time, the door frame that holds the floor door is suspended from the upper horizontal beam by a pin, and the lower end of the door frame is slidably installed on the lower horizontal beam. Even when the substantially rectangular shape is formed, the door frame itself maintains the vertical state. For this reason, if two struts are greatly tilted due to lateral movement due to an earthquake, there is a risk of collision between these struts and the door frame that holds the vertical state. There is a problem that a clearance is required and the size of the apparatus is increased.

  The present invention has been made based on the above-described prior art, and an object thereof is to provide an elevator apparatus capable of preventing a collision between a door frame and a structure adjacent to the door frame without requiring a large clearance. There is.

In order to achieve the above object, the present invention provides an elevator apparatus installed in a building having a seismic isolation device in an intermediate level thereof, a landing door standing at the entrance of the elevator landing, and opening the landing door Supporting means interposed between the door frame that can be held and the door frame and a structure adjacent to the door frame, and rotatably supporting the door frame at one of the center upper end and the center lower end. And a locking means interposed between the door frame and the structure, and locking one of the center upper end and the center lower end of the door frame to the structure so as to be movable up and down , and The door frame is provided with a twist prevention means for preventing the door frame from rotating about a line connecting the support means and the locking means .

  In the present invention configured as described above, the door frame that holds the landing door so that the door can be opened is supported by the structure so that one of the center upper end and the center lower end is turnable by the support means, and the center upper end and One of the lower ends of the center is locked by the locking means so as to be vertically movable. As a result, the door frame is also displaced by the earthquake following the seismic isolation displacement between the base isolation floor and the upper level. Thus, by allowing the door frame to be pivotably supported and displaceable, the movement of the door frame can be synchronized with the displacement of the structure following the seismic isolation displacement due to the earthquake, and thus requires a large clearance. The collision between the door frame and the structure adjacent to the door frame can be prevented.

  Since the movement of the door frame can be synchronized with the displacement of the structure following the seismic isolation displacement due to the earthquake, the collision between the door frame and the structure adjacent to the door frame can be achieved without requiring a large clearance. Therefore, it is possible to reduce the space of the device and to prevent the device from being damaged due to the collision.
