[Diagram 3] FIG. 2 is a three-view diagram of a control panel housing closure plate according to the first embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the embodiments will be described with reference to the drawings. In each drawing, the same reference numerals are used to denote common or corresponding elements, and the description is simplified or omitted. The configurations shown in the embodiments below are examples of the technical ideas related to the present disclosure, and may be combined with other known technologies, or multiple technical ideas described in the present disclosure may be combined. In addition, it is also possible to omit or modify a part of the configuration without departing from the gist of the present disclosure.

[0010] Embodiment 1 FIG. 1 is a perspective view showing an old control panel housing. As shown in FIG. 1, the old control panel housing 2 is installed in the elevator machine room. The old control panel housing 2 is to be replaced with a new control panel 8 during elevator renovation work. The old control panel housing 2 can be separated into two parts: an upper housing section 3 and a lower housing section 4. The lower housing section 4 is fixed to the floor surface by anchors embedded in the concrete floor surface. The upper housing section 3 is fixed to the lower housing section 4 by bolts. The upper housing section 3 and the lower housing section 4 each have a rectangular parallelepiped outer shape.

[0011] Fig. 2 is a perspective view showing the elevator machine room work platform 5 according to the first embodiment. Fig. 2 corresponds to a view seen from the direction of the arrow A in Fig. 1. As shown in Fig. 2, the elevator machine room work platform 5 includes the lower housing part 4 of the old control panel housing 2, and a control panel housing closure plate 6 having a top plate part 7 that covers an opening that is generated above the lower housing part 4 when the upper housing part 3 is separated from the lower housing part 4. The top surface of the elevator machine room work platform 5, i.e., the top plate part 7, is horizontal.

[0012] In this embodiment, the control panel housing closing plate 6 covers the opening above the lower housing part 4, so that work can be safely performed around the lower housing part 4 even if it is left in place. In addition, the lower housing part 4 of the old control panel housing 2 can be used as an elevator machine room workbench 5. For example, a maintenance computer can be placed on the elevator machine room workbench 5 and used. In addition, since it is no longer necessary to cut the lower housing part 4 from the floor surface, the work of cutting is eliminated and the risk of injury during cutting is also eliminated. In addition, a toolbox can be stored inside the area covered by the control panel housing closing plate 6.

[0013] As in the example of Fig. 2, the new control panel 8 may be placed near the old control panel housing 2. A power line or an intercom line is drawn into the lower housing section 4. In order to connect these wires to the new control panel 8, a terminal block for connecting the power line or intercom line in the lower housing section 4 to the wires leading to the new control panel 8 may be provided inside the elevator machine room workbench 5. This allows the space inside the elevator machine room workbench 5 to be used as a space for providing the terminal block.

[0014] FIG. 3 is a three-view diagram of the control panel housing closing plate 6 according to the first embodiment. As shown in FIG. 3, the top plate portion 7 has a rectangular plate shape. The control panel housing closing plate 6 of this embodiment further includes a side plate portion 9 that covers a notch portion 10 provided in the upper part of the side surface of the lower housing portion 4. For convenience, the notch portion 10 of the lower housing portion 4 is shown by a dotted line in FIG. 3. In this embodiment, the notch portion 10 is covered by the side plate portion 9 of the control panel housing closing plate 6, so that work can be performed safely in the surrounding area.

[0015] The top plate portion 7 and the side plate portion 9 of the control panel housing closure plate 6 are connected at the side along the short direction of the top plate portion 7, and the top plate portion 7 and the side plate portion 9 form a substantially perpendicular relationship. The side plate portion 9 protrudes downward from the end portion of the top plate portion 7. This makes it possible to cover the cutout portion 10 without leaving any gaps. In the illustrated example, the side plate portion 9 is provided at each end of the longitudinal direction of the top plate portion 7. The side plate portion 9 has a rectangular shape.

[0016] The longitudinal length of the top plate 7 is longer than the length between the opposing side surfaces of the lower housing 4. In other words, the distance L1 between the side surface plate 9 and the opposite side surface plate 9 is longer than the length of the corresponding portion of the lower housing 4. Therefore, when the top plate 7 is placed in the opening above the lower housing 4, the side surface plate 9 is placed further outward than the side surface of the lower housing 4. This prevents the cutout 10 from being exposed to the outside, allowing work to be done more safely in the surrounding area.

[0017] The control panel housing closure plate 6 of this embodiment further includes an auxiliary plate portion 11 provided on a side surface along the longitudinal direction of the top plate portion 7. The top plate portion 7 and the auxiliary plate portion 11 form an approximately perpendicular relationship. The auxiliary plate portion 11 protrudes downward from an edge along the longitudinal direction of the top plate portion 7. In the illustrated example, the auxiliary plate portion 11 is provided on each of both ends in the lateral direction of the top plate portion 7. The auxiliary plate portion 11 is disposed further outboard than the side surface of the lower housing portion 4 along the longitudinal direction of the top plate portion 7. This can reliably prevent the top plate portion 7 from shifting in the lateral direction. The auxiliary plate portion 11 is provided over the entire length of the top plate portion 7. The auxiliary plate portion 11 has a rectangular shape.

[0018] The side plate portion 9 is provided with a fixing hole portion 12. The fixing hole portion 12 is disposed at a position communicating with a side fixing hole 13 of the lower housing portion 4 that was used for connecting the lower housing portion 4 and the upper housing portion 3 when the top plate portion 7 is disposed in the opening portion of the lower housing portion 4. This makes it possible to bolt the control panel housing closure plate 6 by fastening a bolt inserted into the fixing hole portion 12 into the side fixing hole 13 without providing a new bolt hole in the lower housing portion 4.

[0019] The control panel updating method according to the present disclosure includes an upper housing part separation step of separating and removing the upper housing part 3 of the old control panel housing 2 of the elevator, which is separated into two parts, an upper housing part 3 and a lower housing part 4, arranged in a machine room; a control panel housing closing plate arrangement step of arranging a control panel housing closing plate 6 having a top plate part 7 that covers an opening formed above the lower housing part 4 from which the upper housing part 3 has been removed; and a new control panel arrangement step of arranging a new control panel 8. The order of each step is not limited to the above order. For example, the new control panel arrangement step may be the first step, or the new control panel arrangement step may be the second step. In addition, the control panel updating method according to the present disclosure may further include a terminal block creation step of providing a terminal block for connecting a power line or an intercom line drawn into the lower housing part 4 to a wiring connected to the new control panel 8 inside the part covered by the control panel housing closing plate 6.
