Abstract

PROBLEM TO BE SOLVED: To prevent the narrowing of a cage room and the increase of a weight by providing a back plate arranged on the outer periphery of the side wall of a car and having an installation part in the inside direction of the car and a front plate fixed by a tightening material to the installation part of the back plate. SOLUTION: As a new panel 21 is formed by a modification, the size of a room inside of a car 1 is not changed from that before modification. Therefore, the cage does not become narrow by the modification and the same car space as before modification can be ensured. As the panel 21 is composed of a back plate 9 and a front plate 20 and is the same constitution as the panel before modification, a weight is not changed. Therefore, as the weight of a car main body is also not increased, the consumed electric power at the elevator operation time is not increased. At the installation spot of the elevator, as it is only to remove the front plate 10 and fix the front plate 20 to be replaced to this, the modification work can be carried out in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car panel suitable for repair and a repair method thereof.

[0002]

2. Description of the Related Art First, a conventional elevator car panel will be described with reference to FIGS. FIG. 9 is a cross-sectional view of a conventional elevator car disclosed in, for example, Japanese Utility Model Application Laid-Open No. 1-96482, and FIG. 10 is a diagram corresponding to FIG.
FIG. 11 is an enlarged view of a portion XII in FIG.

In FIG. 9, 1 is an elevator car,
Reference numeral 2 denotes a plurality of panels forming the wall of the car 1, 2a denotes a reinforcing member fixed to the back side of the panel 2, and 3 denotes a connecting member including bolts and nuts (not shown) for fastening the respective panels 2. is there. The cross section of the panel 2 is generally formed by bending both ends into a key shape. The reinforcing member 2a may not have a hat shape as shown in the drawing, or may have no reinforcing member.

When such an elevator has been operated for many years, the surface of the panel 2 may be damaged or dented, requiring repair. Panel 2 design (patterns and colors)
There may be a desire to change things. In such a case, that is, at the time of modification or design change (hereinafter collectively referred to as modification), as shown in FIGS. 10 and 11, a replacement panel 4 having substantially the same shape as the panel 2 is newly manufactured, and this replacement is performed. Cover panel 4 over original panel 2 and
Is adopted.

[0005] Thus, the newly manufactured replacement panel 4 is attached to the car 1 and the repair is realized. In addition,
For repair, there is a method of removing all the original panels 2 and replacing them with replacement panels 4. However, since this method requires a large amount of work, it is difficult to implement the method in a building where an elevator cannot be stopped for a long time, such as an office building. (Repair of the car panel must be completed within one or two days of a normal holiday.) Therefore, the above-described panel configuration is generally employed for panel repair.

[0006]

However, such a conventional elevator car panel has a problem in that the interior dimensions (interior width and depth dimension) of the car 1 are reduced due to the repair. That is, in FIG. 11, assuming that the original interior width of the car 1 is W1 and the depth dimension is L1, the car 1 after the repair is
The interior width W2 and the depth dimension L2 are as follows: W2 = W1-2t L2 = L1-t (where t is the thickness of the replacement panel 4). Therefore, when the conventional panel 2 is repaired, there is a problem that the interior size of the car 1 is reduced and the car is narrowed.
Further, when the conventional panel 2 is repaired, the weight of the replacement panel 4 is added to the car 1, so that the weight of the car body becomes heavy and power consumption during elevator operation also increases.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides an elevator car panel in which the cab does not become narrow and the weight of the car does not increase even if the car panel is modified. Things.
