The relative positions of the opposing gables on the car bodies to be connected may be vertically deviated from each other due to slope tracks and curved tracks, or may be non-parallel to the direction perpendicular to the car body, so the automatic hood The coupling and disengagement must be possible not only on horizontal straight tracks, but also on slopes and curved tracks such as those mentioned above. The connection operation will be described with reference to FIG. 3 in a state where the fixed side viewing seat 1 is deviated upward by +8 minutes with respect to the releasing side canopy seat 2 on a trajectory having a slope, as shown in FIG. 3(A). In order to make the operation easier to understand, the locking device 33 is drawn apart from the release side top seat 2, and other parts are also drawn in a simplified manner to make it easier to understand.

First, in the state shown in FIG. 3(A) before the connection is started, the lifting rod 34 of the lock driving device 36 in the locking device 33 moves upward, and its lower pressing plate 38 pushes up the engagement roller 43, causing the first lock 46 to move downward. The mirror 48 has advanced to the locked position. Further, the arm device 6 is folded by lowering the rod 12 of the arm drive device 11, and the arm bracket 22 engages with the tip of the main arm 8, so that the release side metal frame 5 is moved from the fixed side viewing seat 2. They are separated. In this state, when the operator turns on the starting switch, the lock driving device 36 moves the lifting rod 34 downward as shown in FIG. As a result, the rotating lever 41 rotates clockwise about its support shaft 42, thereby moving the first lock 46 and the lower mirror 48 downward and upward by the same amount. When the movement of both mirrors 46 and 48 is completed, the arm drive device 11 is activated and the rod 12 is moved to the third position.
It moves upward as shown in figure (C). This upward movement causes the main arm 8

As a result of this movement, the release side metal frame 5 is pushed forward by the tip of its main arm 8, guided by the guide metal 59 and pressed against the front surface of the release side canopy seat 2, and the claw 30 is pushed through the elongated hole 29. Further, the upper and lower latches 31 and 32 enter into the release side top seat 2 through the lock grooves 56 and 57, respectively, as shown in FIG. 3(C). At this time,
Since the upper and lower latches 3L and 32 are positioned above the +H distance, they enter the upper part of the lock holes 53 and 53, respectively. Next, the lock drive device 36 is operated and the elevating rod 34 is moved as shown in FIG.
D), and the lower pressing plate 38 moves the retaining roller 43 upward. As a result, the rotary lever 41 rotates counterclockwise to move the bell 46 and lower portion 48 upward and downward by the same amount. At this time, since the upper and lower latches 31 and 32 are deviated upward as described above,
The lower part 48 hits the upper end of the lower latch 32, and the latch 32 is pushed down as shown in FIGS. 3(C) to (D), so that both latches 3L 32 are aligned with the upper and lower lock holes 53,55.

When they match in this way, the release side metal frame 5 is aligned with the main arm 8 as described above.
Both latches 3 are pushed forward by the
1.32 moves into the lock hole 5355 as shown in FIG. 3(D) and fits into it, and then the second lock 46.48 enters and engages with the inner surface of the latch 3L 32 as shown in FIG. 3(D). The door will be locked. Then, the rotation lever 41 is locked by the rotation prevention cylinder 58. Further, as described above, the upward movement of the lifting rod 34 causes the receiver 39 to move upward, and the pawl 30 engaged therewith moves upward against the gas spring 25, thereby moving the arm receiver 22 upward. Then, the arm driving device 11 operates to move the rod 12 downward, and the main arm 8 and the secondary arm 10 of the arm device 6 are folded and returned to their original positions as shown in FIG. 3(E), and the connection work is completed. . Note that these series of operations are automatically performed using microswitches, timers, and the like.

The release operation from the connected state is performed by an operation opposite to the connection operation from the released state.

Next, a description will be given of the connection operation in a state where the fixed side viewing seat 1 is deviated downward by -8 minutes with respect to the releasing side top seat 2 as shown in FIG. 4(A).

In this connection operation, the arm device 6 support device 19 and the locking device 33 operate in the same order as in FIG.
The condition is as shown in Figure 4 (B), with the upper and lower latches 31.3
2 enters the lower part from the lock hole 53.55. In this state, the lock driving device 36 operates in the same manner as in FIG. 3(D), and the upper and lower locks 46 and 48 advance as shown in FIG. 4(C).
The earth bell 46 hits the upper latch 31, and the latch 31 is
Push up both latches 31 from figure (B) to figure 4 (C).
．． 32 to the upper and lower lock holes 53° and 55. When they match in this way, both latches 31 and 32 are
), it is pushed into the lock hole 53.55 and re-admitted 46.
48 enters and engages the inner surfaces of both latches 31 and 32 to effect locking. Then, the arm device 6 returns as shown in FIG. 3(E) to complete the connection.

Further, the operation of releasing from the connected state is performed by an operation opposite to the operation of connecting from the released state.

Next, as shown in FIG. 5, on a curved track, a description will be given of connection and release in a non-parallel manner with respect to the direction perpendicular to the axis of the vehicle body.

In this case as well, the arm device 6, the support device 19 and the lock device 33
performs the same operation as above. At this time, since each of the above-mentioned devices is installed independently on the left and right sides of the canopy, the main It! ii!
