5. The base portion that forms the contact surface is provided, The base portion is formed in the shape of a plate, with one of its planes being the contact surface, as described in claim 1, for the assembly jig of the elevator three-sided frame.
6. The assembly jig for an elevator three-sided frame according to claim 5, wherein the base portion has an opening that exposes the contact portion between the upper frame and the vertical frame at one end face of the corner formed by the upper frame and the vertical frame.
7. The assembly jig for an elevator three-sided frame according to claim 5, wherein the corner outer surface engaging portion has an opening that exposes the contact portion between the upper frame and the vertical frame on the outer surface of the corner formed by the upper frame and the vertical frame.

Description

This invention relates to an assembly jig for a three-sided elevator frame. The elevator's three-sided frame is installed at the elevator landing entrance. The elevator's three-sided frame is assembled by connecting an upper frame and a pair of vertical frames in a roughly U-shape, and is attached to the three sides (top, left, and right) of the landing entrance. The elevator's three-sided frame requires relatively high assembly precision to enhance its aesthetic appearance. Elevator three-sided frames are sometimes delivered to the installation site in an assembled state. However, for elevators with large landing entrances, the elevator three-sided frames also become large, reducing the efficiency of their transportation. Therefore, assembling the elevator three-sided frames at the installation site is being considered. Patent Document 1 discloses an elevator three-sided frame installation device used when assembling and installing an elevator three-sided frame at the installation site. The elevator three-sided frame installation device disclosed in Patent Document 1 comprises an upper installation device and a lower installation device arranged to connect a pair of vertical frames. The upper and lower installation devices each have a long body extending to connect a pair of vertical frames, a pair of gripping devices provided on the long body for gripping the pair of vertical frames, and a connecting member provided in the middle of the long body for adjusting the distance between the pair of gripping devices. Japanese Patent Publication No. 2000-211865 This is a perspective view of the elevator three-sided frame according to the first embodiment of the present invention.This is a perspective view of the assembly jig body according to the first embodiment of the present invention.This is a perspective view of an angle adjustment member according to the first embodiment of the present invention.This is a perspective view from the outside of the elevator three-sided frame showing the assembly jig for the elevator three-sided frame according to the first embodiment of the present invention in use.This is a perspective view from the inside of the elevator three-sided frame showing the assembly jig for the elevator three-sided frame according to the first embodiment of the present invention in use.This is a perspective view of the assembly jig body according to a second embodiment of the present invention. 1. First Embodiment Hereinafter, an assembly jig for an elevator three-sided frame according to the first embodiment of the present invention will be described with reference to Figures 1 to 5. In each figure, common components are denoted by the same reference numerals. [Construction of the elevator's three-sided frame] First, the configuration of the elevator three-sided frame assembled using the assembly jig according to the first embodiment of the present invention will be described with reference to Figure 1. Figure 1 is a perspective view of the elevator's three-sided frame. The elevator three-sided frame 50 shown in Figure 1 is installed at the elevator landing entrance. The elevator three-sided frame 50 has an upper frame 51 and a pair of vertical frames 52 and 53 connected to the upper frame 51. The pair of vertical frames 52 and 53 face each other at a predetermined distance apart. When viewed from the front of the elevator landing entrance, the upper frame 51 and the pair of vertical frames 52 and 53 form a roughly U-shape. Hereafter, the direction in which the pair of vertical frames 52 and 53 face each other will be defined as the left-right direction. The direction approximately perpendicular to the up-down and left-right directions will be defined as the depth direction. Passengers pass through the three-sided elevator frame 50 in the depth direction and board the elevator car (not shown). The upper frame 51 consists of a plate with a plane that is approximately perpendicular to the vertical direction and is formed as a rectangle that is elongated in the horizontal direction. The plane of the upper frame 51 facing upwards forms the outer surface of the elevator three-sided frame 50, and the plane of the upper frame 51 facing downwards forms the inner surface (appearance surface) of the elevator three-sided frame 50. Hereinafter, the plane of the upper frame 51 facing upwards will be referred to as the outer surface 51a, and the plane of the upper frame 51 facing downwards will be referred to as the inner surface 51b. The pair of vertical frames 52 and 53 are each made of a plate with a plane substantially perpendicular to the left-right direction, and are formed into a long rectangle in the vertical direction. The upper ends of the pair of vertical frames 52 and 53 are fastened to both ends of the upper frame 51 in the left-right direction using screws (bolts and nuts). Therefore, through holes are formed in both ends of the upper frame 51 in the left-right direction and in the upper ends of t
