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

Abstract

Provided is a door hanging apparatus which reliably prevents a door wheel from derailing and a door from slanting when the door is opened and closed, and with which there is almost no running resistance from a derailment prevention mechanism. Running surfaces (18a, 18b) vertically facing each other are disposed in upper and lower rails (13a, 13b). First door wheels (19, 20) run in contact with the lower rail (13b), and are rotatably supported by a first door wheel supporting member (21) which suspends a door (11). Second door wheels (24, 25) are rotatably supported by swinging members (22, 23) which are swingably linked to the first door wheel supporting member (21), and are disposed so as to be able to make contact with the upper rail (13a). A drive linking part (26) is configured to hold and link the door (11) to an opening/closing drive mechanism (12). An elastic linking mechanism (27) includes elastic parts (30a, 30b) which are able to change the relative positions of the second door wheels (24, 25) and the drive linking part (26), and connects the swinging members (22, 23) to the drive linking part (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;...
