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 open-close direction thereof without adjusting the positions of a latching part and a part being latched in a locking device. A drive connection unit (21) is provided with one from among the latching part (17) and the part being latched (18) in the locking device (13) that locks the door (11) to a structure in a fully-closed position through the latching of the latching part (17) and the part being latched (18), and is connected to an open-close drive mechanism (12). A door roller unit (22) is connected to the door (11) and provided with door rollers (36a, 36b, 36c) that run on a rail (19) fixed on the structure, and supports the door (11) in a suspended state freely sliding on the rail (19). A variable connection unit (23) connects the drive connection unit (21) and the door roller unit (22) in a manner enabling the alteration of the relative positions of the drive connection unit (21) and the door roller unit (22) in a direction along the lengthwise direction of the rail (19).

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 pr...

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.
