Description

This invention relates to an elevator side panel structure, an elevator car having this side panel structure, and an elevator system equipped with this car. In elevator cars, side panels have been proposed in which enamel plates and plate bodies are joined using adhesive (see, for example, Patent Document 1). The side panel described in this document has an enamel plate forming a U-shaped cross-section with its ends bent, and a plate body adhesively fixed to the back surface of the enamel plate. Furthermore, a reinforcing member is attached to the end of the enamel plate on the back side of the plate body. This reinforcing member has a U-shaped cross-section and is arranged in multiples along the short side of the enamel plate.

Hereinafter, examples of elevator devices, elevator cars, and elevator side panel structures according to embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the following examples. In the figures described below, common components are denoted by the same reference numerals. Furthermore, in the drawings used herein, identical or corresponding components are denoted by the same reference numerals, and repeated descriptions of these components may be omitted. [Elevator System Configuration] Figure 1 shows a schematic diagram of the elevator system. The elevator system shown in Figure 1 is installed in a hoistway (not shown). In the elevator system, one end of the main rope 2, which is wound around the hoisting machine 1, is suspended through a pair of left and right lower car pulleys 4A and 4B located at the bottom of the elevator car 3, and then fixed at an upper position in the hoistway. The other end of the main rope 2 is suspended through a pulley 6 of the counterweight 5, and then fixed at an upper position in the hoistway. The elevator system moves vertically within the hoistway by rotating the hoisting machine 1, causing the elevator car 3, which is attached to one end of the main rope, and the counterweight, which is attached to the other end of the main rope. [Elevator car configuration] Next, Figure 2 shows a perspective view of the elevator car 3. Figure 2 shows the elevator car 3 viewed from the entrance side towards the rear side. The elevator car 3 comprises a floor plate 31, a top plate 32 positioned above the floor plate 31, and a baseboard 33 installed so as to rise from the floor plate 31. The elevator car 3 also comprises a plurality of rear side panel structures 100 installed on the baseboard 33 in the depth direction when viewed from the front of the entrance/exit, and side panel structures 100 installed on the baseboard 33 in the left-right direction when viewed from the front of the entrance/exit. In the elevator car 3 shown in Figure 2, the rear side of the elevator car 3 is composed of a plurality of side panel structures 100, but the side panel structure 100 may be composed of a single piece. Similarly, the side panel structure 100 on the side is composed of a single piece, but the side panel structure 100 may be composed of a plurality of pieces. [Structure of the side panel] Next, Figures 3, 4, and 5 show the configuration of the side plate structure 100 used in the elevator car. Figure 3 is a front view of the side plate structure 100 from the inside of the elevator, and Figure 4 is a cross-sectional view of the side plate structure 100 shown in Figure 3 along line A-A. Figure 5 is an exploded view of the side plate structure 100. As shown in Figures 3-5, the elevator side panel structure 100 comprises a surface plate 110, a reinforcing member 120, and a fixing member 130 that secures the surface plate 110 and the reinforcing member 120 by adhesive. The fixing member 130 also comprises a first fixing member 131 and a second fixing member 132. (Surface plate) The surface plate 110 is joined to the reinforcing member 120 via a fixing member 130.
