DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a push-in sliding door device mainly used in a car of a railway vehicle.

In vehicles with this type of sliding door, in relation to the sliding door and the fixed side wall, when the sliding door is closed, the inside of the vehicle is always on the same plane, so the first step in opening the sliding door is to pull the sliding door away from the vehicle body. , you need to avoid a closed sliding door and then pull it open.

Conventionally, in this type of opening/closing mechanism, the sliding door rides on a rotating rail that is separate from the linear rail for traveling, and the sliding door is mounted on a rotating rail that is separate from the linear rail for traveling. Alternatively, a door wheel with crank arms at the top and bottom of each sliding door can be installed at the top and bottom of each sliding door, and this crankshaft can be rotated to separate it from the vehicle body. Various measures have been taken, such as moving the sliding doors outwards, so that the closed sliding doors can be pulled open. However, this method has disadvantages such as a complicated mechanism and complicated operations to avoid mutual interference between the mechanisms.

As mentioned above, in a push-in sliding door, when the sliding door is closed, the inside of the sliding door becomes flush with the sliding door itself or the inner surface of the fixed wall on the side of the vehicle body, completely blocking the vehicle body opening and preventing the loaded object from rolling or falling. It must be able to prevent damage caused by rainwater, etc., and must be able to withstand the vibrations of the vehicle and internal pressure from luggage, and must be locked to prevent it from opening spontaneously in the unlikely event that the sliding door is opened. It is located far away from other closed sliding doors or on the outside of fixed side walls, and after avoiding mutual interference, the outside of these doors can be easily pulled and moved by human power, and the structure and operation are as simple as possible. It is necessary to

In the present invention, the upper and lower rails on which the sliding doors run or are guided are provided with branches, and each sliding door is guided by a door roller having a different position or shape, so that the sliding doors always travel on a fixed route without interfering with each other. , and is equipped with a mechanism that allows the left and right sliding doors to be opened and closed in one operation without any order, which eliminates the above-mentioned drawbacks and satisfies the requirements for push-in sliding doors.

The sliding door will be opened. As shown in FIG. 6a, this lower vertical door roller 9 has an inner flange diameter larger than an outer flange diameter, while the guide rail 20 provided at the branch part has a diameter as shown in FIGS. 10 and 11. Since the cross-sectional shape of the rail is formed as shown in a, the door roller 9 is guided by the high inner flange, transfers from the guide rail 20 to the lower rail 6, and moves straight. Similarly, the upper horizontal door roller 8 at the left end of the sliding door comes out of the upper curved rail 17' of the upper rail 5 shown in FIG. 7 and rolls to the left.

As shown in FIG. 5, this upper door roller 8 is installed with a step at a higher position than the upper door roller 8' at the right end of the sliding door, while the branching part of the upper rail 5 is as shown in FIGS. 7 and 8c. The upper half of the curved entrance of the upper curved rail is separated by a partition wall, so
This upper horizontal door car, which is located at a higher position, does not enter the upper curved rail but goes straight ahead. In this case, as shown in FIG. 8a, the guide plate 1 located at a low position within the upper rail 5
This sliding door passes above the upper door wheel 8 without any trouble.

The clutch on the upper surface of the opening/closing handle boss 22 is disengaged, and the opening/closing shaft 11 rotates counterclockwise.
The rollers at the tips of the crank arms 27 and 29 at the upper and lower ends are caught on the protruding part of the crank guide 32 fixedly installed at the upper and lower center of the side of the vehicle, and the sliding door is pulled toward the vehicle body by the subsequent rotation of the opening/closing handle. The locking arms 28 and 30 at both the upper and lower ends of the opening/closing shaft engage with the lock catch 33 forming a part of the crank guide, and the sliding door is closely fixed to the side of the vehicle. .

The sliding door is securely and firmly fixed by fitting the tip of the sliding door on the other end side with the drainer. In this case, the lock arms 28, 30 are constructed and arranged so that they are simply subjected to a tensile force, and no rotational torque is generated on the opening/closing shaft. Further, the forward and backward movement of the sliding door that occurs when the vehicle is connected is restrained by the engagement of the crank arms 27 and 29 with the crank guide 32 and by the contact with the drain at the other end of the sliding door.

The opening/closing operation of the left sliding door is performed in complete contrast to the above-mentioned right sliding door, and in the above embodiment, a case was described in which there are two sliding doors on the left and right, but in a long freight car, a set of these two sliding doors is used. Several sets of sliding doors can be used in combination.

Vertical door rollers are installed, and these door rollers are connected to the car body side structure through guide plates provided in the groove walls of the upper rail and upper curved rail, and guide rails provided at the branching parts of the lower rail and lower curved rail. The sliding door can be easily opened by automatically sorting the upper curved rail and lower curved rail provided on the upper and lower rails along the side beams of the stand frame and rolling in a predetermined path. .

In addition, the operation of pushing in and pulling out sliding doors can be easily performed by rotating an opening/closing handle fixed to an opening/closing shaft provided at one end of each sliding door, and by the rotational lever action of the crank arm and lock arm provided at the upper and lower ends of the opening/closing handle. Moreover, the sliding door can be locked and unlocked by simply holding the opening/closing handle via the clutch at the upper end of the opening/closing shaft rotation control rod, which is attached to the opening/closing shaft so that it can slide up and down, and the push-up wheel at the lower end. All operations from unlocking to locking can be performed reliably and easily in a preset order with a simple operation of just pulling in the direction.

As explained above, in this embodiment, a horizontal door roller is provided at the top of the sliding door, an upper rail is provided inside the vehicle body to guide the sliding door, a lower vertical door roller is provided at the bottom of the sliding door, and side beams are provided. A case has been described in which a lower rail is provided on the outside to support the weight of the sliding door and guide it to perform a predetermined function. The lower door roller and lower rail used in this example were used upside down, and the lower door roller and rail were similar to the upper door roller and rail used in this example, turned upside down. It is also possible to change the arrangement of the door rollers and rails, such as by providing a lower door roller that only functions to regulate the direction of movement of the sliding door and to support the weight of the sliding door.

According to the present invention, an upper rail is provided at the top and a lower rail is provided at the bottom, and door wheels are provided at the top and bottom of the sliding door that is guided by each rail to open and close, and positions corresponding to the positions of the door rollers of the closed sliding door.
