And a second link mechanism 22 that is connected to the second link mechanism 22. Note that, in FIG. 2, arrows F and R indicate the front and the rear, respectively, but a pair of link mechanisms 20 are provided at the front part and the rear part of the door body 10.

Here, as shown in FIG. 3 (when the door is closed) and FIG. 4 (when the door is open), the first link mechanism 2 is used.
A base end of 1 is rotatably coupled to the body 1 (roof portion 2) via a bracket 23 fastened to the body 1 by a bolt or the like. In addition, the first link mechanism 21
The front end of the door body 1 (upper half 11) is connected to the door body 1 through a bracket 24 that is fastened to the door body 10 by bolts or the like.
It is rotatably coupled to 0.

The base end of the second link mechanism 22 is the body 1
Bracket 25 fastened to (side portion 3) with bolts or the like
Is rotatably coupled to the body 1 via. Further, the tip of the second link mechanism 22 has a bracket 26 that is fastened to the door body 10 (lower half portion 12) by bolts or the like.
Is rotatably coupled to the door body 10 via.

The first link mechanism 21 includes a pair of link members 21a and 21b for connecting the roof portion 2 of the body 1 and the upper half 11 of the door body 10, and these link members 21a and 21b are described above. So that the bracket 2
The roof part 2 and the upper half part 11 are joined by 3, 24.

The link members 21a and 21b have a curved or bent form (that is, not a straight line) as can be seen from FIG. 3 or FIG. 4, but the roof part 2 of the body 1 and the upper half part of the door body 10 are connected. A substantially parallel four-link mechanism is formed between the two and 11. Since each of the link members 21a and 21b has the curved shape in this manner, the body does not extend to the inside of the vehicle as shown in FIG. Arranged along the line. Therefore, due to the positional relationship between the link members 21a and 21b, the effective space of the vehicle compartment is secured without disturbing the actual use.

Further, in the vertical opening / closing door of the present invention, the second link mechanism 22 is provided on the side of the body 1 on the side of the vehicle compartment.
It has an operation lever 27 that is interlocked with the (link member 22a). The operating lever 27 is set at a portion of the bracket 25, but is arranged at a position easily accessible within the vehicle compartment. Further, as shown in FIGS. 6 and 7, the operation lever 2

Next, the operation of the vertical opening / closing door of the present invention having the above structure will be described. For example, as shown by in FIG. 5, when the closed door body 10 is opened, the operation lever 27
The second link mechanism 22 is rotated upward by placing the hand on and rotating from the top to the bottom. As a result, the door body 10 starts to open, and the state shifts to. In this case, the operation lever 27 can be easily reached in the passenger compartment, and the door body 10 can be easily opened. Therefore, even a vehicle with a high vehicle height can be operated easily and smoothly.

Further, the damper stay 29 operates in the vicinity of the state indicated by in the middle of the opening of the door body 10 to urge the second link mechanism 22 to rotate upward. As a result, the door body 10 opens almost automatically upward, and the operation can be performed extremely easily.

Further, in the vicinity of the state where the door body 10 is being opened, the upper half portion 11 and the lower half portion 12 of the door body 10 are pivoted around the hinge 13 and bent.
Since the door body 10 is bent when the door body 10 is opened as described above, the space required for the opening and closing operation of the door body 10 can be substantially reduced without being largely projected outward of the vehicle.

When the door main body 10 is further opened by the action of the damper stay 29, the upper half portion 11 and the lower half portion 12 are integrated in parallel with each other like the state of the folded door main body 10. When the door is opened, the upper half portion 11 and the lower half portion 12 are integrated in parallel, so that the door main body 10 becomes the body 1.
It protrudes from the side portion 3 in a so-called eaves-like manner, and functions as, for example, a rain shield (or a sun shade in some cases). As shown in FIG. 5, the overhang length L of the door body 10 is preferably L = 40 to 50 cm or more.

Further, when the opened door body 10 is closed, it can be easily and smoothly operated by pushing down the door body 10 in a manner substantially similar to the case of opening.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and can be appropriately modified within the scope of the present invention. For example, the present invention can be effectively applied not only to the side door as in the above-described embodiment but also to a back door.

[0031]

As described above, according to the present invention, in this type of vertical opening / closing door, one end of the door body, which is opened substantially parallel to the roof portion, is projected like a canopy to function as a rain shield. This can effectively prevent the room from getting wet. In addition, the door opening and closing operation can be easily performed with the operation lever in the passenger compartment, which eliminates the inconvenience that the door is out of reach, etc., and the folded shape when opening and closing the door reduces the space required for the opening and closing operation. Then, the parking space can be effectively used. Further, when the door is opened, the door main body is held at a high position substantially parallel to the roof portion, so that there is an advantage that the head space can be secured to improve the entry / exitability.
