FIG. 3 is a perspective view showing an outline of the opening work floor panel 21. As shown in FIG.

  The opening work floor panel 21 according to this embodiment includes a fixed floor panel 22 forming a frame having an opening, and an opening floor panel 24 disposed so as to close the opening and which can be lifted and removed; It consists of

Here, FIG. 4 is a plan view of the opening work floor panel 21 as viewed from above. FIG. 5 is a perspective view showing the open floor panel 24 in a lifted state.
The fixed floor panel 22 has an opening 23 large enough to accommodate the rescue door 18. The rescue door 18 is concentric with the opening 23. The fixed floor panel 22 is fixed to the bracket 25 disposed on the long side of the opening 23 and the bracket 27 disposed at the corner by a fastening member. The opening floor panel 24 is a panel having substantially the same vertical and horizontal dimensions as the opening 23, and can completely cover the opening 23.

  Such an opening floor panel 24 is mounted on a portion exposed from the opening 23 of the brackets 25, 27 and is supported by the brackets 25, 27. In this case, the open floor panel 24 is simply mounted without being fixed to the brackets 25, 27. Thus, the open floor panel 24 can be simply lifted and removed.

  Further, since the opening floor panel 24 is not removed except in the case of an emergency or inspection, in order to prevent the opening floor panel 24 from rising or shifting due to the vibration accompanying the elevation of the car during elevator operation. As the means of, as shown in FIG. 4 to FIG. 7, the following mechanism is provided.

  In these FIGS. 4 to 7, reference numeral 26 denotes a turn plate. The turn plate 26 is pivotably attached to both sides of the open floor panel 24 via a hinge 30.

  In FIG. 4, the turn plate 26 is horizontal and flush with the open floor panel 24, which is the closed position of the turn plate 26. FIG. 6 shows a cross section of the turn plate 26 in the closed position. In FIG. 5, the turn plate 26 is pivoted into a vertical position relative to the open floor panel 24, which is the open position of the turn plate 26. FIG. 7 shows a cross section of the turn plate 26 in this open position. A notch 29 having the same shape as the turn plate 26 is formed on both sides of the opening floor panel 24, and the turn plate 26 is pivotably attached to close the notch 29.

  As shown in FIGS. 6 and 7, a plate-like first stopper 32 is fixed to the lower surface of the opening floor panel 24 so as to protrude toward the notch 29. In this case, one longitudinal side edge of the turn plate 26, which is parallel to the pivot axis, is placed on the first stopper 26. Furthermore, a plate-like second stopper 34 is attached to the other side edge of the turn plate 26 in the longitudinal direction. The second stopper 34 abuts on the lower surface of the edge of the fixed floor panel 22 when the turn plate 26 is in a horizontal posture.

The elevator car work floor according to the present embodiment is configured as described above, and the operation and effects thereof will be described next.

  The open floor panel 24 provides a similar footing to the work floor panels 20A-20E during maintenance and inspection operations. In FIG. 6, the dimensions of the turn plate 26 do not differ much from the size of the sole of the worker, so even if the worker steps on the turn plate 26, the first stopper 32 receives a load and becomes a detent. The turn plate 26 is held horizontally so as not to turn, and the operator is not torn off.

  Since the open floor panel 24 only rests on the brackets 25 and 27, it may lift up due to vibration and shaking during normal elevator operation. In this embodiment, when the opening floor panel 24 is lifted, the second stopper 34 contacts the fixed floor panel 22 so that the lifting can be suppressed.

  In an emergency, when opening the rescue door 18, the opening floor panel 24 can be removed as follows. As shown by arrow A in FIG. 6, when the end on the second stopper 34 side of the turn plate 26 is pushed down with a finger, the turn plate 26 pivots clockwise in FIG. As shown in FIG. 7, when the turn plate 26 is vertically erected, the space between the opening floor panel 24 and the turn plate 26 is opened. The opening floor panel 34 can be lifted and easily removed by putting a hand into this opening and replacing the first stopper 32 with a handle. In FIG. 5, the open floor panel 24 can be removed to open the exposed rescue door 18.
