Note that the update engagement device 62 uses components of the update hall door device 50 arranged in the hall 5 in the following third stage modification, and can be diverted in the third stage modification. Further, if the existing engagement device 71 does not get in the way when the engagement mechanism 31 and the update engagement device 62 of the temporary update car door device 45 are gripped and engaged, the existing engagement device 71 is not removed. You may leave it.

  Next, as the third stage, the existing landing door 12 and the modified existing landing door device 80 are sequentially updated to the updated landing door 10 and the updated landing door device 50, and the updated landing door 10 and the updated landing are added to all the landings 5. A door device 50 is provided. Then, the existing unlocking mechanism 36 is removed from the temporary update car door device 45 to obtain the car 1 modified to the update car door 9 and the update car door device 19 shown in FIG. The update engagement device 62 attached to the update landing door 10 may be used by removing the update engagement device 62 of the modified existing landing door device 80, or the update engagement device 62 may be used in advance. It may be attached to the high-speed door 7b.

  By refurbishing as described above, even when the updated landing door device 50 and the modified existing landing door device 80 are mounted in a mixed manner without being unified at all the landings 5, the temporary updated car door device 45 is engaged. The mechanism 31 can correspond to both the update landing door device 50 and the update engagement device 62 of the modified existing landing door device 80.

Furthermore, the existing lock device 51b of the modified existing landing door device 80 is unlocked by the existing unlocking mechanism 36 of the temporary update car door device 45, and the update lock device 51a of the update landing door device 50 includes the update car door 9 and the update. It is unlocked by a strip 67 interlocked with the initial opening operation of the landing door 10.
Therefore, when the car 1 to which the temporary updated car door device 45 is mounted faces the landing 5, not only the opening / closing operation of the updated landing door 10 but also the opening / closing operation of the existing landing door 12 is linked to the opening / closing operation of the updated car door 9. Can be done.

  In other words, the existing landing door 12 can be opened and closed without any problem in conjunction with the operation of the updated car door 9, and the modified existing landing door device 80 and the updated landing door device 50 are mixed in the entire landing 5 without being unified. Even if it is, the elevator can be operated.

  This eliminates the need to repair the existing landing door device 70 on all floors at once to remove the existing landing door device 70 and replace it with the updated landing door device 50. First, a simple modification is performed in which the update engagement devices 62 are attached to all the existing landing door devices 70, and the modified existing landing door devices 80 are sequentially updated during a limited time period when there are few elevator users such as holidays and nights. The work of exchanging with the landing door device 50 can be performed. That is, the landing door device can be repaired without stopping the operation of the elevator over a long period of time.

According to the elevator door device refurbishment method according to the present invention, the existing unlocking mechanism 36 is added to the updated car door device 19 during the refurbishment, and the update engagement device 62 having a simple structure is attached to the existing landing door 12. Thus, the operation of the elevator can be realized while the existing landing door device (modified existing landing door device 80) to which the update engagement device 62 is attached and the updated landing door device 50 are mixed. Therefore, it is not necessary to newly develop a member having a special structure such as a new type of gripping device as in the prior art, and the modified existing landing door device 80 and the updated landing door device 50 are all installed during the repair of the door device. A method of repairing an elevator door device that enables operation of the elevator while being mixed without being unified at the landing can be realized at low cost.
Further, since the update engagement device 62 is a general-purpose component and has a simple structure, the number of components does not increase and maintenance management becomes troublesome unlike a new gripping device.

  In the first stage of renovation, the existing unlocking mechanism 36 has been described as being removed from the existing car door device 35 and attached to the update car door device 19 to form the temporary update car door device 45. The mechanism 36 is not limited to the one to which the mechanism 36 is attached. If the existing locking device 51b of the existing landing door device 70 can be unlocked, another unlocking mechanism is previously provided on the high-speed door 7a. May be. Here, the existing unlocking mechanism 36 or other unlocking mechanism attached to the update car door device 19 in order to unlock the existing locking device 51b of the existing hall door device 70 is defined as a temporary unlocking mechanism.

  In addition, although the existing car door 11 has been described as being replaced with the updated car door 9, the existing car door 11 may be used as it is. In this case, it is only necessary to remove the existing car door device 35 from the car 1 and attach the updated car door device 19 instead in the first stage of renovation. Further, the existing car door device 35 may be partially used for the updated car door device 19.

  Further, in the third stage of refurbishment, it has been described that the existing landing door 12 is replaced with the updated landing door 10, but the existing landing door 12 may be used as it is. In this case, it is only necessary to remove the existing unlocking mechanism 36 after the modified existing hall door device 80 is updated to the updated hall door device 50 in the third stage of renovation.

  Further, the elevator car 1 and the landing 5 have been described as being provided with a laterally open two-piece pulling door, respectively, but the car 1 and the landing 5 are provided with a laterally-opening two-piece pulling door. The present invention can be applied to the car 1 and the landing 5 as long as a lateral pulling door is provided.

The existing gripping device 41 and the existing engagement device 71 are not limited to those of the above-described embodiment, and are held and engaged with each other when the car 1 is landed, and the opening / closing operation of the existing car door 11 is performed. As long as the existing hall door 12 can be opened and closed in conjunction with the vehicle.
Moreover, although the existing gripping device 41 is disposed on the existing car door 11 and the existing engagement device 71 is disposed on the existing landing door 12, the existing gripping device 41 is disposed on the existing landing door 12. The present invention can be applied even if the existing engagement device 71 is disposed on the existing car door 11.

  Further, the update engagement mechanism 31 and the update engagement device 62 are not limited to those of the above-described embodiment, and are engaged and engaged with each other with a simple configuration and interlocked with the opening / closing operation of the update car door 9.
