Description

  Embodiments described herein relate generally to an elevator car work floor.

  In the elevator car, the surface of the ceiling panel faces the car room, and the back surface of the ceiling panel is a surface called the car top. Reinforcing materials are vertically and horizontally attached to the back surface of the ceiling panel, that is, on the car. In addition to the upper beam constituting the car frame, various electric devices are installed on the car.

  In elevator installation and maintenance inspection work, there are many work that must be carried out by an operator on the car. In general, there are many irregularities on the car due to the presence of reinforcing materials and electrical equipment, and there is a risk that the car will fall over. Therefore, in order to ensure the safety of work on the car, a work floor that flattens the car has been proposed (for example, Patent Document 1).

Conventionally, this type of work floor is installed on a car when an elevator is newly installed, and cannot be applied to an existing elevator car.
Therefore, recently, a method for flattening an existing elevator car has been studied.

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

  The open floor panel 24 is not removed except during an emergency or inspection, so that the open floor panel 24 can be prevented from being lifted or displaced by vibrations caused by raising or lowering of the car during elevator operation. As shown in FIG. 4, the following mechanism is provided as shown in FIGS.

  4 to 7, reference numeral 26 denotes a turn plate. The turn plate 26 is attached to both sides of the opening floor panel 24 through a hinge 30 so as to be turnable.

  In FIG. 4, the turn plate 26 is horizontal and flush with the open floor panel 24, and this state 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 turns and assumes a vertical posture with respect to the opening floor panel 24, and this state is an open position of the turn plate 26. FIG. 7 shows a cross section of the turn plate 26 in this open position. A cutout 29 having the same shape as that of the turn plate 26 is formed on both sides of the opening floor panel 24, and the turn plate 26 is pivotably attached so as to close the cutout 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 side edge in the longitudinal direction of the turn plate 26 parallel to the pivot axis is placed on the first stopper 26. Further, a plate-like second stopper 34 is attached to the other side edge in the longitudinal direction of the turn plate 26. The second stopper 34 comes into contact with the lower surface of the edge of the fixed floor panel 22 when the turn plate 26 is in a horizontal posture.

The work floor on the elevator car according to the present embodiment is configured as described above. Next, the operation and effect will be described.
As shown in FIG. 2, work floor panels 20 </ b> A to 20 </ b> E and an open floor panel 24 are laid on the ceiling panel 12 to cover the reinforcing members 14 and 15 attached to the ceiling panel 12.
