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 is mounted on the front surface, and a mounting bracket 56 having a U-shaped striker 54 fixedly mounted on the rear surface is mounted using screws or the like using these holes 50A and 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.
And 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 (see FIG. 5). A pin 66A is planted in the lock plate 66 and engages with an engagement groove 68A at the end of the fork lever 68. 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 2 described above.
It is engaged with the third arm 24C of 4 to transmit the rotational force (the third arm).

Next, the first lock mechanism E provided on both sides of the lower opening / closing body D will be described with reference to FIG.

In the same figure, since the left and right sides are similar, only the left side portion is representatively shown, and the reference numeral is attached to the reference numeral to distinguish it from the right side (subscript B). 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 and the bracket 84A of the lock device 80A are fixed to the panel 70 that constitutes the lower opening / closing body D, and the pin 8 provided on the bracket 84A is fixed.
A release lever 16A is supported rotatably around 6A and connected to the operating rod 14A of the first link mechanism G described above. Then, 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 opening operation of 34 is not transmitted to the first link mechanism G that releases the first lock mechanism E. That is, as shown in FIGS. 1 and 3, 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 operating pin 26 engaged with the second operating lever 24 and its arcuate elongated hole 24D is in the position shown in FIG. At this time, the glass hatch 50 is in a closed state, so that even if the first operating lever 23 rotates counterclockwise in this position, the operating pin 26 floats in the arc-shaped elongated hole 23D of the key-shaped end portion 23B. Bell crank that constitutes the first link mechanism G
The drive arm 10C of 10 has a positional relationship in which an operating force cannot be transmitted.

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] When the glass hatch 50 is opened, a key is inserted into the key cylinder 36 to change the locked state shown by the two-dot chain line in FIG. 1 to the unlocked state shown by the solid line. The rotation lever 38 is rotated. Then, the key cylinder 36 is pushed against the spring (not shown). Then the bell crank 40 is rotated by the pressing protrusion 38A and the operating rod 42 is moved.
Is pulled down, and the second operating lever 24 is rotated clockwise in the third drawing. Due to the rotation of the second operation lever 24, the fork lever 68 engaged with the third arm 24C rotates counterclockwise around the pin 72A, and the lock plate 66 rotates clockwise in the fifth drawing to latch. Disengage from 64. Then, the glass hatch 50 opens. Further, 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 shown in FIG. By the clockwise rotation of the second operating lever 24, the operating pin 26 is 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, and is shown in the fourth illustration. Is moved to and held at the position.

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 as shown in FIG.
The release levers 16A and 16B are rotated via A and 14B to release the first lock mechanism E. At this time, the operating pin 26 moves the second operating lever 24.
With respect to, only moving in the arc-shaped long hole 24D 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.

In this state, the key cylinder 36 is operated by the key to bring the rotary lever 38 into the locked state shown by the chain double-dashed line in FIG.

[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.
Since the key cylinder is once in the unlocked position because the idling mechanism that disables the release operation of the first link mechanism only when the second lock mechanism is not released, once the key cylinder is in the unlocked position, the opening and closing operation of the upper and lower opening / closing bodies is performed by the key plate. It is possible to obtain a door opening / closing device for a vertical opening / closing vehicle which can be performed without using and is excellent in operability and durability.
