The two linear bearings are pivotally attached to each other, and the linear guides are provided so that the linear bearings slide such that the first support arms of the two linear bearings can intersect each other when opening and closing. Next, similarly, the second support arm fixedly extended from each door pivotally mounts two guide rollers at one end, and one of the guide rollers is fitted into the above-mentioned turning arm which constitutes the door opening / closing drive unit and rolls. In this way, the two doors are opened and closed by transmitting the turning motion of the turning arm to the second support arm via the guide roller.

That is, a passenger car using two slide type doors is used as a carrier, and a door opening / closing lever mounted on the carrier side for turning operation and a door opening / closing drive interlocking with the door opening / closing lever are used. Section, a first support arm fixedly extended from each of the two doors, and a second support arm fixedly extended from each of the two doors to transmit the opening / closing action of the door opening / closing drive unit. And the first support arms fixedly extended to the respective doors when the two doors are opened and closed are formed to be crossable with each other,
When the two doors are in the open position, they are stacked in the center of the passenger car for storage.

[0007]

The passenger car of the carrier is provided with two rows of seats in the center of which the passengers can sit while facing backward when viewed from the side. For this reason, the passenger space in the passenger car is divided into two rows of seats, and doors for passengers to get on and off are provided in the front and rear of the traveling direction of the carrier. Then, when the door is opened and passengers get on and off the passenger car, the doors on both sides are accommodated in the middle frame of the passenger car in a superimposed manner.

Next, a door opening / closing lever having a roller pivotally attached to a tip end thereof is pivotally attached to the suspension machine for suspending the passenger car to the gripping device in a vertically rotatable manner. Then, one end of a flexible cable forming a door opening / closing drive unit is pivotally attached to the door opening / closing lever.

Next, in the door opening / closing drive unit incorporated in the passenger car, the first pinion meshing with the first rack to which the other end of the above-mentioned flexible cable is connected is pivotally mounted on the pinion shaft so as to be rotatable horizontally. Secure the crank lever to. Next, connecting springs are pivotally extended by bearing points at both ends of the crank lever, and tie rods and second racks are arranged and fixedly connected to the extended lines. Next, the swivel arms are fixedly extended to the second racks at both ends, and the second pinions that swivel around the swivel shaft are engaged with each other.

On the other hand, each door has a first support arm having two linear bearings rotatably pivoted at its tip and a second support arm having two guide rollers pivotally pivoted at its tip. Stick out two arms. The linear guides in which the linear bearings of the first support arm are slidably guided are arranged vertically apart from each other at the same position in the center in plan view, and one guide roller of the second support arm rolls. Guide rails to be guided are installed on both sides. Separately from this, another guide roller pivotally attached to the second support arm is fixed to the second pinion so that the guide roller rolls while being guided by the turning arm that integrally turns. That is, the second support arm and the swing arm are interlocked with each other with the guide roller interposed.

Now, when the gripping device of the carrier travels on the rail arranged at the stop, the roller which pivotally connects the door opening rail or the door closing rail arranged in parallel to the rail to the tip of the door opening / closing lever is rolled. The door opening / closing lever swings upward or downward in accordance with the inclination of the door opening rail or the door closing rail. And, the turning operation of the door opening / closing lever is the first on the side of the passenger car, which is connected to the other end side by the flexible cable forming the door opening / closing drive section.
Move the rack directly. As a result, the first pinion meshed with the first rack rotates, and the crank lever fixed to this also rotates. By this rotation operation, the second rack, which is connected to both ends of the crank lever at the bearing points by the connection spring and the tie rod, is directly moved. Then, the second pinion meshed with the second rack rotates, and the swivel arm fixedly extended to this also swivels at the same time. Further, when the swing motion of the swing arm is transmitted to the second support arm by the guide roller pivotally attached to the second support arm, the first support arm of each door is guided to the linear guide, and at the same time, the second support arm is guided. The support arm is guided by the guide rail to open and close. When the two doors move to the open position, the first support arms of the doors move so as to intersect with each other in a plan view, so that the two doors are superposed on the middle frame of the passenger car and accommodated. To do so. Next, when the door is in the closed position, the connecting springs pivotally attached to both ends of the crank lever at bearing points turn beyond the dead point to become compressed, and the restoring force at that time brings the door to the closed position. I try to press it.

At the same time, stoppers using leaf springs are fixed to the connecting springs pivotally attached to both ends of the crank lever and the tie rods connected between the second racks, respectively.

As described above, the present invention is provided with the sliding type doors for passengers to get in and out on the side of the passenger car in the forward and backward direction of the carrier.
The present invention relates to a door opening / closing mechanism for automatically opening / closing this door as the carrier moves. In particular, when the doors on both sides are opened, they can be stored in the middle frame of the passenger car so that they can be stowed so that passengers can get on and off by shortening the carrier interval when the doors are open. This has the effect of reducing the required area.

By interposing a connecting spring on the second rack for opening and closing the door, when an object or a passenger is caught in the closing door, the connecting spring is compressed to protect the object or the passenger, and thereafter. , When an object or a passenger is removed from the door, the connecting spring is restored and the door is normally closed. Further, the stopper provided on the side of the second rack comes into contact with the bracket at the fixed position to restrict the operation of the second rack, so that the door is locked. If it is necessary to open the door in an emergency or during maintenance, the release rod can be directly pressed from outside the vehicle, or the operation rod can be turned with a tool to push the release rod.
It also has a lock release mechanism that allows you to open the door by rotating the pinion to remove the stopper from the bracket to release the locking action, and swinging the connecting spring past the dead point to open the door. The effect of the present invention is great.
