  • the worker M can perform maintenance inspection work by opening the front surface 13a of the control board 13. Then, when the maintenance inspection is completed, the front surface 13a of the control board 13 is closed, and the wire 21 is wound onto the winding sheave 18 by operating the manual winding handle 19.
  • the winding sheave 18 rotates smoothly in the direction of wire wind up, and rotation in the direction of wire pay out is prevented by the engagement between the feed pawl and the ratchet wheel of the winding sheave 18, preventing the control board 13 from unexpectedly swinging down.
  • the control board 13 pivots around the pivoting shaft 17, and returns to the stored position with the back surface 13d parallel to the ceiling 2a of the machine room 2.
  • control board 13 is constructed so as to be movable between a stored position with a back surface 13a thereof placed parallel to the ceiling 2a of the machine room 2, and a maintenance inspection position hanging down from the ceiling 2a of the machine room 2, installation space and maintenance inspection space for machinery in the machine room 2 can be utilized efficiently, enabling the floor area of the machine room 2 to be reduced.
  • the degree freedom in the layout of a building can be increased.
  • control board 13 positioned in the maintenance inspection position is in a vertical direction, the control board 13 can be inspected and maintained in a normal vertical state, preventing deterioration in maintenance inspection workability.
  • control board 13 is disposed so as to avoid being vertically above the installation region of the hoisting machine 6 raised above the floor surface, increases in ceiling height resulting from the control board 13 being installed on the ceiling 2a are suppressed, enabling increases in building height to be suppressed.
  • the hook 15, the winding sheave 18, and the inverting sheave 20 are disposed so as to be positioned in a common vertical plane, but the mounting position of the winding sheave 18 may also be offset from the vertical plane by installing an inverting sheave in the path of the wire 21 between the winding sheave 18 and the inverting sheave 20. In that case, the degree of freedom in the mounting position of the winding sheave 28 can be increased.
  • the inverting sheave 20 is mounted to the ceiling 2a of the hoistway 2, but the inverting sheave 20 may also be mounted to a side wall 2b in a vicinity of the ceiling 2a facing the lower surface 13c of the control board 13 when positioned in the stored position.
  • Figure 3 is a partial perspective showing a vicinity of a driving portion of a pivoting mechanism in an elevator apparatus according to Embodiment 2 according to the present invention.
  • an electric motor 25 is mounted to a mounting plate 26 mounted to a side wall 2b of a machine room 2 such that rotational torque from the electric motor 25 is transmitted to a rotating shaft 28 by means of a speed reduction mechanism portion 27.

  • the winding sheave 18, the electric motor 25, the speed reduction mechanism portion 27, and the rotating shaft 28 constitute a driving portion of a pivoting mechanism.
  • Embodiment 2 is constructed in a similar manner to Embodiment 1 above except for the fact that the electric motor 25, the speed reduction mechanism portion 27, and the rotating shaft 28 are used instead of the manual winding handle 19.
  • Embodiment 2 by driving the electric motor 25 to rotate, rotational torque from the electric motor 25 is transmitted to the winding sheave 18 by means of the speed reduction mechanism portion 27 and the rotating shaft 28, driving the winding sheave 18 to rotate.
  • the wire 21 is wound onto the winding sheave 18, moving the control board 13 from the maintenance inspection position to the stored position. Furthermore, by driving the electric motor 25 so as to rotate in a reverse direction, the wire 21 is paid out from the winding sheave 18, moving the control board 13 from the stored position to the maintenance inspection position.
  • Embodiment 2 Consequently, similar effects to those in Embodiment 1 above are also exhibited in Embodiment 2.
  • Embodiment 2 because an electric motor 25 is used as a driving portion, the work load on the worker M when moving the control board 13 is significantly reduced.
  • Figure 4 is a longitudinal section schematically showing a machine room of an elevator apparatus according to Embodiment 3 of the present invention.

  • control board 13 can also be positioned in the stored position parallel to the ceiling 2a of the machine room 2 by operating the manual winding handle 19 to wind the wire 21 onto the winding sheave 18. Furthermore, the operating panel 13 can be positioned in the maintenance inspection position hanging down from the ceiling 2a of the machine room 2 by operating the manual winding handle 19 to pay the wire 21 out from the winding sheave 18.
  • Embodiment 3 it goes without saying that an electric motor 25, a speed reduction mechanism portion 27, and a rotating shaft 28 may also be used instead of the manual winding handle 19.
  • a wire 21 is explained as being used for the traction member, but the traction member is not limited to the wire 21, and a chain, for example, may also be used. In that case, toothed portions meshing with the chain are formed on outer circumferential portions of the winding sheave 18 and the inverting sheave 20.
