Problems solved by technology
Therefore, when the door pulley moves on the rail, a predetermined movement resistance is generated in the derailment prevention mechanism, and the driving efficiency of the door opening and closing drive by the opening and closing driving mechanism is reduced.
In addition, due to the movement resistance, it is easy to promote the wear of the door pulley

A door hanging apparatus is provided that can reliably prevent the derailing of door rollers and the tilting of a door when the door is opened and closed, while having little running resistance caused by a derailing prevention mechanism. Upper and lower rails (13a, 13b) are provided with running surfaces (18a, 18b) opposing each other in the vertical direction. First door rollers (19, 20) run in contact with the lower rail 13b, and are rotatably supported to a first door roller supporting member 21 that suspends a door 11. Second door rollers (24, 25) are rotatably supported to swing members (22, 23) swingably connected to the first door roller supporting member 21, and are provided so as to be capable of coming into contact with the upper rail 13a. A drive connection portion 26 is provided for holding and connecting the door 11 to an open-close drive mechanism 12. An elastic connection mechanism 27 includes an elastic portion (30a, 30b) capable of changing the relative position between the second door rollers (24, 25) and the drive connection portion 26, and connects the swing members (22, 23) to the drive connection portion 26.
Description
technical field [0001] The present invention relates to a hanging door device that supports a door installed on a structure and is driven to open and close by an opening and closing drive mechanism in a state of being slidably and freely suspended relative to the structure, and is connected to the opening and closing drive mechanism, and includes the A door installation for a hanging door installation. Background technique [0002] Conventionally, there is known a hanging door that is installed on a structure and driven to open and close by an opening and closing drive mechanism, is supported on the structure in a state of being slidably movable relative to the structure, and is connected to the opening and closing drive mechanism. device (for example, refer to Patent Document 1). In Patent Document 1, as a door hanging device applied to a railway vehicle as a structure, there is disclosed a door hanging device including: a rail member having an upper rail and a lower rail;...
