The plug door lock device is provided with a plurality of lock mechanisms, each of which has a motor for locking the door leaf. Each of the lock mechanisms has a lock arm capable of coming into engagement with an engaged portion fixed to the door leaf, a link member having one end-side portion coupled rotatably to the lock arm and a rotation preventing mechanism.

Plug door lock device and plug door system

One object is to provide a plug door device that can make a contribution to a size reduction thereof, while suppressing a decrease in airtightness of a door. A plug door device is provided with an electric motor, a plug operation portion that moves a door in a width direction of a vehicle, a front-back operation portion that moves the door in a front-back direction of the vehicle, a movement suppressing portion that can suppress movement of the door in the front-back direction, and a planetary gear mechanism that distributes a drive force of the electric motor to the plug operation portion when movement of the door in the front-back direction is suppressed by the movement suppressing portion, and distributes a drive force of the electric motor to the front-back operation portion when movement of the door in the front-back direction is not suppressed by the movement suppressing portion.

Plug door device

A plug door opening-closing apparatus includes a lock mechanism, a drive mechanism, and a door support mechanism. The lock mechanism is directly or indirectly arranged on one of the upper and lower portions of at least one door of a vehicle. The lock mechanism locks the door when completely closed so that the door does not open. The drive mechanism is coupled to the lock mechanism and drives the lock mechanism to switch the door from an unlocked state to a locked state. The door support mechanism is mechanically coupled to the lock mechanism and supports the door. When the completely closed door is switched from the unlocked state to the locked state, the door support mechanism is adapted to hold the door and hinder outward displacement, in a vehicle width direction, of the other portion of the door where the lock mechanism is not arranged.

A plug door opening-closing apparatus, which is adapted for use with a vehicle having a vehicle front-rear direction and a vehicle width direction, includes a door hanger configured to be coupled to a door panel of the vehicle, a movable guide configured to guide movement of the door hanger in the front-rear direction and move in the width direction, a guide support member that guides movement of the movable guide in the width direction, and an interlock mechanism mechanically connected to the movable guide.

A vehicle door locking device includes a switching portion capable of switching between a first state in which the switching portion makes contact with a door to inhibit the door from moving in an opening direction no less than a distance required for removing an object caught in the door, and a second state in which the movement of the door of no less than the distance is not inhibited. The switching portion has a cam that rotates according to an opening/closing operation of the door. The rotation of the cam by a predetermined angle or more is inhibited in the first state, and the rotation of the cam is allowed in the second state.

Vehicle door locking device

Provided is a small plug door device having a slide base is installed slidably in a vehicle width direction relative to a fixed base. A door drive mechanism for moving one door in a vehicle front-rear direction via a connecting portion has a drive portion including an electric motor, a drive wheel member, a follower wheel member, and an endless member, and is installed on the slide base. A guide portion guides a shaft portion provided on the connecting portion so as to move the shaft portion in a vehicle width direction. In a double-speed rail in which a pinion is disposed between two racks, one rack is connected to the slide base, the other rack is connected to the door side, and the pinion is connected to the connecting portion.

It is aimed to provide a railway vehicle plug door device capable of easily ensuring airtightness between a side structure body and a door leaf even if the railway vehicle plug door device is installed in a side structure body having a structure assembled by joining structural members by welding and including a bent part. A frame body is mounted on a part constituting an entrance in a side structure body by a mechanical fastening structure. A seal member is mounted on at least one of a door leaf and the frame body and held in close contact with both the door leaf and the frame body when the door leaf closes the entrance.

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 baseis installed slidably in a vehicle width direction relative to a fixed base. A door drive mechanismfor moving one doorin a vehicle front-rear direction via a connecting portionhas a drive portionincluding an electric motor, a drive wheel member, a follower wheel member, and an endless member, and is installed on the slide base.

A door opening and closing apparatus includes a lock mechanism having an engaging member that engages with a lock member provided in a door when the door is in a fully closed state, and a link mechanism that has three link members, is configured to be able to undergo deformation into a linear state and a bent state, and restricts rotation of the engaging member by being brought into the linear state. A central link member among the three link members has a first face and a second face that are pressed by a projecting shaft. The link mechanism changes to the bent state when the first face is pressed, and changes to the linear state when the second face is pressed. The first face and the second face are provided so as to have a positional relationship in which the first face and the second face intersect each other.
