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

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.
摘要:
The invention relates to a device to be installed at a vehicle for performing an operation of opening and closing a panel door, comprising a slide base installed on the fixed base slidably in a vehicle width direction; and a door drive mechanism that has a drive wheel member to which a driving force is input, at least one follower wheel member provided in association with the drive wheel member, and an endless member that is looped around the drive wheel member and the follower wheel member so as to circle therearound, the door drive mechanism being installed on the slide base in the range from the front end portion of the entrance of the vehicle to the rear end portion of the entrance of the vehicle as viewed in the direction of the vehicle width so that the door drive mechanism slides with the slide base in the vehicle width direction.

Provided is a small plug door device capable of performing an opening/closing operation and a plugging operation with a door drive mechanism for causing a force in a vehicle front-rear direction to act on a door, and further applicable also to a one-panel sliding door. A slide base 12 is installed slidably in a vehicle width direction relative to a fixed base 11. A door drive mechanism 13 for moving one door 104 in a vehicle front-rear direction via a connecting portion 19 has a drive portion 13a including an electric motor 21, a drive wheel member 13b, a follower wheel member 13c, and an endless member 13d, and is installed on the slide base 12. A guide portion 15 guides a shaft portion 14 provided on the connecting portion 19 so as to move the shaft portion 14 in a vehicle width direction. In a double-speed rail 16 in which a pinion 16c is disposed between two racks (16a, 16b), one rack 16b is connected to the slide base 12, the other rack 16a is connected to the door 104 side, and the pinion 16c is connected to the connecting portion 19.
