The height of the side plate portion 106a is set lower than the height of the side plate portion 106b by the thickness of the swing panel 110 described later.
A panel receiving portion 111 extending toward the side plate portion 106b in parallel with the bottom plate portion 105 is formed on the upper side of the side plate portion 106a. In addition, a hinge attachment portion 112 extending toward the side plate portion 106a in parallel with the bottom plate portion 105 is formed on the upper side of the side plate portion 106b.

  The accommodating part 102 has an accommodating space 107 for accommodating the control board 103 therein. In addition, the side plate portion 106 c of the housing portion 102 is formed with a drawing port 108 (see FIG. 4) for drawing the wiring 101 into the housing space 107. The length of the wiring 101 in the accommodation space 107 is set to a sufficient length so that excessive stress is not applied to the wiring 101 when the swing panel 110 rotates as will be described later.

  A swing panel 110 having a substantially rectangular flat plate shape is provided on the upper portion of the accommodating portion 102 via a hinge 109 so as to be rotatable with respect to the accommodating portion 102. The hinge 109 is provided on the hinge mounting portion 112 of the side plate portion 106b so that the rotation axis of the hinge 109 extends along the X direction.

  The swing panel 110 is formed to have a size capable of closing the opening formed in the upper part of the housing portion 102. One end of the swing panel 110 in the short direction is fixed to a hinge 109. When the other end portion in the short direction of the swing panel 110 abuts on the panel receiving portion 111, the swing panel 110 closes the opening formed in the upper portion of the housing portion 102.

That is, the rotation of the swing panel 110 when the swing panel 110 rotates from the storage position to the exposure position is restricted by the upper frame 82.

  When the swing panel 110 is in the exposed position, the surface opposite to the mounting surface of the control board 103 faces the upper surface of the ceiling portion 92 in the vertical direction through the swing panel 110.

  As for the installation location of the control device 100, when the rotation of the swing panel 110 is restricted by the upper frame 82, the swing panel 110 is suitable for the work by the operator with respect to the horizontal plane parallel to the upper surface of the ceiling portion 92. It is set to incline at a predetermined angle.

  The lid part 104 is a substantially square box-like member (see FIG. 2) whose lower part is opened. When the upper part of the accommodating part 102 is inserted and fitted into the opening of the lid part 104 from below, the lid part 104 covers the upper part of the accommodating part 102.

<Operation of elevator device 1>
Next, the operation of the elevator apparatus 1 will be described with reference to FIG. FIG. 7 is a diagram for explaining the operation of the elevator apparatus 1. In FIG. 7, illustrations of members constituting the car frame 8 other than the upper frame 82, the rope 6, and the like are omitted.

  When the worker performs work using the control board 103 in the elevator apparatus 1 (for example, maintenance work such as operation confirmation and connection confirmation of peripheral devices), the worker first starts the hall H of the building where the elevator apparatus 1 is installed. The height of the car 4 is adjusted so that the control device 100 can be reached from the car.

  Next, the operator removes the lid 104 (not shown in FIG. 7) fitted to the upper portion of the accommodating portion 102. Next, the operator holds the end of the swing panel 110 on the entrance / exit 12 side (door device 94 side) in the short direction, and rotates the swing panel 110 from the housed position to the exposed position. Then, the worker confirms the operation and connection of the peripheral device.

  In the elevator apparatus 1 in this embodiment, the accommodating part 102 in which the swing panel 110 which supports the control board 103 is provided is provided in the entrance / exit 12 side. Therefore, the operator does not need to get on the upper surface of the ceiling portion 92 of the cab 9 in order to rotate the swing panel 110. That is, the worker can work using the control board 103 while staying in the elevator hall H of the building. Therefore, the operator can easily perform the operation using the control board 103.

  In addition, the worker may rotate the swing panel 110 when performing the work using the control board 103. Therefore, it is possible to make the worker easily perform the operation using the control board 103 as compared with the case where the housing portion 102 is rotated.

  Further, when the swing panel 110 is in the storage position (for example, when the elevator apparatus 1 is running), the swing panel 110 supports the control board 103 in a state of being laid on the upper surface of the ceiling portion 92. For this reason, a sufficient clearance can be secured between the upper portion of the car 4 and the building during traveling.

  Further, since the upper frame 82 regulates the rotation of the swing panel 110 in the rotation direction when the swing panel 110 is rotated from the accommodation position to the exposure position, the swing panel 110 is prevented from excessively rotating. be able to. Further, since the upper frame 82 restricts the rotation of the swing panel 110 so that the swing panel 110 is inclined at an angle suitable for the operator's work, the efficiency of the work using the control board 103 is increased. Moreover, since it is not necessary to separately provide a member for restricting the rotation, an increase in manufacturing cost of the elevator apparatus 1 and a complicated manufacturing operation can be suppressed.

  Further, the side plate portion 106c of the accommodating portion 102 is formed with a drawing port 108 (see FIG. 4) for drawing the wiring 101 into the accommodating space 107. The length of the wiring 101 in the accommodating space 107 is the swing panel. It is set to a sufficient length so that the wiring 101 is not excessively stressed when the 110 rotates. For this reason, it is possible to suppress the occurrence of connection failure such as disconnection of the wiring 101 caused by the rotation of the swing panel 110.

  Further, when the swing panel 110 is in the storage position, the mounting surface of the control board 103 is opposed to the bottom plate part 105 of the storage unit 102 in the vertical direction. That is, since the mounting surface of the control board 103 faces downward, it is possible to suppress the adhesion and accumulation of dust on the mounting surface of the control board 103 compared to the case where the mounting surface of the control board 103 faces upward. be able to.
