Next, a second lock mechanism that locks the upper opening / closing body C and the lower opening / closing body D in the closed state will be described.

In this embodiment, the upper opening / closing body C is composed of a glass hatch 50, and two holes 50A and 50B are formed in the lower edge portion thereof. Then, a fixed handle 52 on the front surface and a mounting bracket 56 on which a U-shaped striker 54 is fixedly mounted on the rear surface are attached by screws or the like using these holes 50A, 50B.

On the other hand, a locking device is provided on the concave step D1 at the upper edge of the lower opening / closing body D.
60 is provided. As is well known, the locking device 60 includes a honing 62 and pins 62A and 62B supported by the honing 62.
A latch 64 and a lock plate 66 that are rotatably supported around the pins 62A and 62B, and a spring (not shown) that biases the latch 64 in the releasing direction. A pin 66A is planted in the lock plate 66 and engages with an engaging groove 68A at the end of the fork lever 68 (see FIG. 5). The fork lever 68 is rotatably supported around a pin 72A provided on a bracket 72 fixed to a panel 70 that constitutes the lower opening / closing body D, and the fork portion 68B at one end is provided with the second operating lever 24 described above.

The first locking mechanism E is the second locking mechanism F described above.
Since it is basically the same except that the attachment site is different, only an external description will be given. That is, the housing 82A of the lock device 80A and the bracket 84A are fixed to the panel 70 that constitutes the lower opening / closing body D, and the first link mechanism G is rotatably operated around the pin 86A provided on the bracket 84A. A release lever 16A connected to the rod 14A is supported.
A striker 88A is fixed to the side edge of the vehicle opening B.

The operation of the embodiment of the present invention having the above structure will be described below.

[Closed state of the upper and lower opening / closing bodies C and D] In this state, the lower opening / closing body D is locked by the first locking mechanism E, and the upper opening / closing body C and the lower opening / closing body D are locked by the second locking mechanism F. What has been done is as described above.

Therefore, even if the fixed handle 52 is pulled to open the glass hatch 50, it cannot be opened because it is locked by the second lock mechanism F.

In addition, even if the handle 34 is operated to open the tailgate D to release the first lock mechanism E, the handle
The rotational movement of 34 is not transmitted to the first link mechanism G that releases the first lock mechanism E. That is, FIG. 1 and FIG.
As shown in the figure, the counterclockwise rotation of the handle 34 causes the first operating lever 23 to rotate counterclockwise via the operating rod 25. However, since the key cylinder 36 is not operated at all, the second operating lever 24 and its arcuate long hole are formed.
The actuating pin 26 engaging 24D is in the position shown in FIG. Therefore, the glass hatch 50 is in the closed state, and even if the first operating lever 23 rotates counterclockwise in such a position, the operating pin 26 only loosens in the arc-shaped elongated hole 23D of the key end 23B. The positional relationship is such that the operating force cannot be transmitted to the drive arm 10C of the bell crank 10 that constitutes the first link mechanism G.

Therefore, even if the handle 34 is operated and the first operating lever 23 is rotated counterclockwise, the first link mechanism G is guided in the arc-shaped elongated hole 23D without any influence. That is, the tailgate D cannot be opened, that is, it acts as an idle swing mechanism.

[Opening of upper opening / closing body, closed state of lower opening / closing body] To open the glass hatch 50, insert a key into the key cylinder 36 and operate the rotary lever 38 from the locked state shown by the solid line in the direction of the arrow to set two points. Rotate to the unlocked state shown by the chain line. Then, the operating rod 40 is pulled down, and the second operating lever 24 is rotated clockwise in the third drawing. The fork lever 68 engaged with the third arm 24C by the rotation of the second operation lever 24 is pin 72A.
The lock plate 66 is rotated counterclockwise with respect to as a center to rotate the lock plate 66 clockwise in the fifth drawing to release the engagement from the latch 64. Then, the glass hatch 50 opens. When the glass hatch 50 is opened, the lock plate 66 is held at the position shown in FIG. 6 in the state of being rotated clockwise from the closed state. The clockwise rotation of the second operating lever 24 causes the operating pin 26 to be guided along the linear elongated hole 23C of the first operating lever 23 and the linear elongated hole 10D of the drive arm 10C of the bell crank 10. 4 Moved to the position shown and held.

Therefore, when the handle 34 is rotated in this state, the first operating lever 23 is rotated counterclockwise as described above, but this time, the bell crank 10 is moved through the operating pin 26 and the drive arm 10C.
Is rotated counterclockwise in FIG. 4, and the operating rod 14A,
The release levers 16A and 16B are rotated via 14B to release the first lock mechanism E. At this time, the actuating pin 26 only moves in the arcuate elongated hole 24D with respect to the second actuating lever 24 and has no effect.

Thus, the tailgate D can be opened.

[Closing the Vertical Opening / Closing Body] First, when the tailgate D is closed, the first lock mechanism E operates and the closed state is maintained. Next, when the glass hatch 50 is closed, the second lock mechanism F operates and the closed state is maintained.

At this time, the fork lever 68 simultaneously rotates clockwise and the second
Pull the operating rod 40 through the operating lever 24 Key cylinder
Since the 36 is rotated to the locked state, the upper and lower opening / closing bodies are automatically locked.

[Effects of the Invention] As is apparent from the above description, according to the present invention, it is possible to reliably prevent an erroneous operation such as opening only the lower opening / closing body, and to open and close the upper and lower doors at one place.
Further, since it is provided with the idling mechanism, it is possible to obtain a door opening / closing device for a vertical opening / closing vehicle which is excellent in operability and durability. Further, when the upper opening / closing body is closed, the key cylinder is locked and the link mechanism is in an idling state, so that it is possible to reliably prevent forgetting to lock without locking each time opening / closing.
