Definitions

  • the present invention relates to an elevator car ceiling apparatus in which an internal ceiling plate is disposed further inside a car than an external ceiling plate.
  • elevator car ceiling apparatuses have been proposed that have: a ceiling plate in which an emergency rescue hatchway is disposed; and a suspended ceiling plate that is disposed under the ceiling plate and in which an inspection opening portion is disposed.
  • a cover that opens and closes the emergency rescue hatchway is disposed on the ceiling plate, and a cover that opens and closes the inspection opening portion is disposed on the suspended ceiling plate.
  • the emergency rescue hatchway is opened by the cover that is disposed on the ceiling plate being rotated outward from the car.
  • the inspection opening portion is opened by the cover that is disposed on the suspended ceiling plate being rotated inward into the car (See Patent Literature 1).
  • patent literature 2 is related to an elevator car, in which a removable cover plate is lifted upwards and stored in a space between an external ceiling plate and a plate located adjacent the original position of the removed cover plate.
  • the present invention aims to solve the above problems and an object of the present invention is to provide an elevator car ceiling apparatus that can reduce an opening action region required in order to open an inspection hatchway, and that can also facilitate movement of users between an interior portion of a car and a top of the car.
  • the inspection hatchway opening and closing cover is held by the internal ceiling plate when in an inspection hatchway closing position that closes the inspection hatchway, and is also removed from the internal ceiling plate by being displaced to a holding release position that is offset horizontally from the inspection hatchway closing position to disengage holding by the internal ceiling plate, the inspection hatchway opening and closing cover can be removed from the internal ceiling plate in a state that is close to horizontal. Consequently, an opening action region required in order to open the inspection hatchway can be reduced. Because passengers, rescuers, etc., can pass through the inspection hatchway and the rescue hatchway with the inspection hatchway opening and closing cover removed from the internal ceiling plate, movement of users between an interior portion of a car and a top of the car can be facilitated.
  • Figure 1 is a plan that shows an elevator car ceiling apparatus according to Embodiment 1 of the present invention.
  • Figure 2 is a cross section that is taken along Line II - II in Figure 1 .
  • Figure 1 is a plan that shows the car ceiling apparatus when viewed from inside a car.
  • an external ceiling plate 2 ( Figure 2 ), and an internal ceiling plate 3 that is disposed further inside a car 1 than the external ceiling plate 2 (i.e., below the external ceiling plate 2) are disposed on an upper portion of a car 1.
  • an external ceiling plate 2 and an internal ceiling plate 3 that face each other vertically are disposed on the upper portion of the car 1.
  • a plurality of lighting devices 4 ( Figure 1 ) for illuminating inside the car 1 are disposed between the external ceiling plate 2 and the internal ceiling plate 3.
  • Each of the lighting devices 4 is mounted to a lower surface of the external ceiling plate 2.
  • a rescue hatchway 5 that is disposed so as to avoid each of the lighting devices 4 is disposed on the external ceiling plate 2.
  • a rescue hatchway opening and closing cover 6 that opens and closes the rescue hatchway 5 is also mounted on the external ceiling plate 2.
  • the rescue hatchway opening and closing cover 6 is mounted to the external ceiling plate 2 by means of a hinge 7 that is disposed on an edge portion of the rescue hatchway 5.
  • the rescue hatchway opening and closing cover 6 can be displaced between a rescue hatchway closing position that closes the rescue hatchway 5, and a rescue hatchway opening position that is positioned further outside the car 1 than the rescue hatchway closing position, and that opens the rescue hatchway 5 by being rotated around an axis of the hinge 7.
  • An edge portion of the rescue hatchway opening and closing cover 6 is engaged in the external ceiling plate 2 when the rescue hatchway opening and closing cover 6 is in the rescue hatchway closing position (i.e., when the rescue hatchway opening and closing cover 6 closes the rescue hatchway 5).
  • displacement of the rescue hatchway opening and closing cover 6 further inside the car 1 than the rescue hatchway closing position is restricted by engagement of the rescue hatchway opening and closing cover 6 with the external ceiling plate 2.
  • a lighting opening 8 ( Figure 1 ) that faces each of the lighting devices 4, and an inspection hatchway 9 that faces the rescue hatchway 5 are disposed on the internal ceiling plate 3.

Holding of the inspection hatchway opening and closing cover 11 by the internal ceiling plate 3 is disengaged by the inspection hatchway opening and closing cover 11 being displaced to a holding release position that is offset horizontally from the inspection hatchway closing position ( Figure 7 ). Consequently, the inspection hatchway opening and closing cover 11 is mounted onto the internal ceiling plate 3 by being displaced to the inspection hatchway closing position and held by the internal ceiling plate 3, and is removed from the internal ceiling plate 3 by being displaced to the holding release position to disengage holding by the internal ceiling plate 3.
  • the inspection hatchway opening and closing cover 11 has: a plate-shaped cover main body 12 that has a design surface and a back surface; a first cover frame 13 that is disposed on a first end portion of the cover main body 12; and a second cover frame 14 that is disposed on a second end portion of the cover main body 12.

Displacement of the inspection hatchway opening and closing cover 11 between the inspection hatchway closing position and the holding release position is performed inside a range between the first bracket 15 and the second bracket 16 (an inter-bracket range).
  • the inspection hatchway opening and closing cover 11 is engaged by the first bracket 15 when in the inspection hatchway closing position ( Figure 2 ), and is engaged by the second bracket 16 when in the holding release position ( Figure 7 ).
  • the first bracket 15 has: a fixed portion 15a that is fixed to the internal ceiling plate 3; a vertical plate portion (a horizontal direction restricting portion) 15b that extends upward from the fixed portion 15a; and a lateral plate portion (the vertical direction restricting portion) 15c that extends horizontally from an upper end portion of the vertical plate portion 15b.
