摘要： PROBLEM TO BE SOLVED: To make a single type of door locking device available for both right and left opening directions of an elevator door. SOLUTION: In this door locking device, the movement of an engagement device 8 which moves according to opening and closing actions of the door, is transmitted to a locking device 21 which conducts locking movement through a joining member. This device is provided with the engagement device which is constituted of a movable engagement piece 9 which rotates by receiving the driving force of a door opening/closing device, and a pair of links 11 whose one end is supported by a support shaft 10 linked to the movable engagement piece 9 so as to make free rotation and whose other end is linked to the joining member 20 so as to make free rotation, and is constituted so that a pair of the links 11 may be rotated with the four-joint link or in a parallel condition. By turning the engagement device 8 by 180 degrees and fitting it, it is possible to make a single type of part available for both the right and left opening directions and reduce the number of part items by a half.

摘要： PROBLEM TO BE SOLVED: To provide an elevator renewal work method low in total costs by reducing the generation of noises or dusts as much as possible during renewal work and employing latest elevator control and safety technologies. SOLUTION: In an elevator renewal work method where the engaging member of a car door opening/closing device is engaged with the engaging member of a landing site door and at least the car door or the engaging part of an elevator device having the car door and the landing site door interlockingly opened/closed is replaced, a three-way frame 1, a threshold 2, a landing site door 3, a hanger 4, a header 5 and a post angle 6 are used intact except when safety standards or designs are fully examined, because sufficient durability is provided. For interlocking the opening/closing of a new car door by a new car door opening/closing device with the existing landing site door 3, only a newly provided engaging device 7, a newly provided locking device 8 as a safety device or a newly provided door closing device 9 is attached. In this case, by using bolt holes with existing parts removed, new parts are attached without opening any additional bolt holes. Thus, noises or dusts are prevented from being generated.

摘要： PURPOSE: To execute renewal works of an elevator without any necessity of cutting of a building and hole boring in a threshold by connecting a fulcrum of a main link of a landing door link and an end of a tension spring for closing the door to a header. CONSTITUTION: Open/close drive force of doors 3a, 3b are transmitted to a door link 9a, which is attached to the door 3a by setting a groove 10a as a fulcrum, secondarily transmitted to a main link using a shaft 10c as a fulcrum, and to the door 3b using a shaft 10d as a fulcrum. The upper end of the main link is connected to a header 1 by setting a shaft 10e as a fulcrum so as to be allowed rotational movement. One end and the other end of a spring 12 for closing the doors are connected to the main link and the header 1 respectively. This constitution can eliminate cutting works of the floor 5 of a building and penetration hole boring process for a fixed bolt in a threshold 6 in such renewal works as diverting the threshold.
