Door suspension apparatus and door apparatus equipped with the same

Abstract

Disclosed is a door suspension apparatus that is capable of adjusting the position of a door in the opening and closing direction thereof without adjusting the positions of a locking portion and a locked portion of a locking device. A drive connection portion (21) is provided with one of a locking portion (17) and a locked portion (18) of a locking device (13) for locking a door (11) to a structure in a fully closed position through locking between the locking portion (17) and the locked portion (18), and is connected to an open-close drive mechanism (12). A door roller portion (22) is connected to the door (11) and provided with door rollers (36a, 36b, 36c) that travel on a rail (19) fixed in the structure, and that supports the door (11) in a state in which the door (11) is suspended to the rail (19) so as to be slidably moved. A variable connection portion (23) connects the drive connection portion (21) to the door roller portion t (22) such that the relative position between the drive connection portion (21) and the door roller portion (22) along the lengthwise direction of the rail (19) can be changed

Description

technical field [0001] The present invention relates to a door hanging device that supports a door installed on a structure and is driven to open and close by a switch drive mechanism in a state of being slidably suspended relative to the structure, and is connected to the switch drive mechanism. Door fittings for door hangers. Background technique [0002] At present, there is known a door hanger that is installed in a structure and is driven open and close by a switch drive mechanism in a state of being slidably suspended relative to the structure and is connected to the switch drive mechanism (for example, refer to Patent Documents 1, 2). Patent Document 1 and Patent Document 2 disclose that in a railway vehicle as a structure, a door suspended by a door hanger is opened and closed by a switch drive mechanism connected to the door hanger. In addition, in the door hanging devices disclosed in Patent Document 1 and Patent Document 2, door rollers that move on rails are p...

AI Technical Summary

Problems solved by technology

However, the space for accommodating the door hanging device and the locking device above the opening is usually quite narrow, so the positions of the locking part and the locked part of the locking device must also be adjusted after the door position adjustment has been completed. Adjusting the homework to become quite difficult homework

In addition, in order to adjust the position of the locking part and the locked part, after adjusting the position of the predetermined member relative to the long hole, the means of tightening the bolt is often used to fix the position, especially in this case, it is easy to cause tightening. The case where the position of the specified member relative to the long hole is shifted when bolting

Therefore, there is a problem that it is very difficult to adjust the position of the locking part and the locked part, and at the same time, a lot of man-hours are required.
