Description

  The present invention relates to a vehicle including a gull wing type door.

  Conventionally, there are various vehicles equipped with a gull-wing type door. For example, in Patent Document 1, a hinge portion having a hinge shaft extending in the front-rear direction is provided on a ceiling portion of a vehicle, and a door that opens and closes the entrance is connected by the hinge portion, and the door is centered on the hinge shaft. A vehicle that can be opened and closed is disclosed.

JP 2008-37264 A

However, in the configuration in which the hinge portion for connecting the door to the ceiling portion is provided as in the vehicle according to Patent Document 1, the hinge portion is on the occupant's head or on the direction in which the occupant gets on or gets off in the vehicle width direction. When provided, the hinge part may interfere with the passenger's getting on and off operation.
Here, it is conceivable that the hinge portion is arranged away from the occupant's head or the like in the front-rear direction. However, when the vehicle is small, the size of the ceiling portion is small and the door can be opened and closed satisfactorily. The installation position of the hinge part is restricted due to the necessity of supporting the door with a good weight balance, and the hinge part may be inevitably provided on the occupant's head.

Specifically, for example, a two-seat front and rear vehicle with a narrow ceiling, where one of the doors arranged side by side is a left door that opens to the left, and the other is a right door that opens to the right In such a small vehicle, the size of the ceiling portion is small, and the installation position of the hinge portion is restricted.
Furthermore, in general, it is preferable to form a boarding opening on the side of a seated occupant in a vehicle to ensure comfort of getting on and off, but in a small vehicle with a small ceiling portion, the side of the seated occupant When the door is connected with the hinge part of the ceiling part while forming the entrance to the door, a hinge part may be provided above the central area of the entrance in a side view in order to support the door with a good weight balance. Preferably, the installation position of the hinge part is restricted.
As described above, in a small vehicle, when the hinge portion is provided on the ceiling portion, the hinge portion may have to be provided on or near the occupant's head, and the comfort of getting on and off is impaired by the hinge portion. A situation may arise.

  The present invention has been made in view of the above circumstances, and is a vehicle in which a hinge portion for opening and closing a door is provided on a vehicle ceiling portion, and it is preferable for comfort of passengers getting on and off through a boarding opening that opens and closes the door. It is an object to provide a vehicle that can be secured.

As a means for solving the above problems, the invention according to claim 1 is characterized in that the door (25, 26) connected to the ceiling (R) by the hinge (27, 29) provided on the ceiling (R). And the door (25, 26) is rotatable about the hinge shaft (28, 30) of the hinge portion (27, 29), and the hinge shaft of the hinge portion (27, 29). (28, 30) extends obliquely with respect to the front-rear direction, and the vehicle is a two-seater front and rear, and the doors (25, 26) are provided side by side with a left door (25) and a right A door (26) is included, and the hinge shaft (28) of the hinge portion (27) of the door provided on the front side of the left door (25) and the right door (26) is provided on the front side. The entrance (EL) that is opened by the door is toward the opening side Wherein the inclined so as to extend rearward in accordance with.

The invention according to claim 2 includes a door (25, 26) connected to the ceiling part (R) by a hinge part (27, 29) provided on the ceiling part (R), and the door (25, 26) In a vehicle in which the hinge shaft (28, 30) of the hinge portion (27, 29) can be rotated about the hinge shaft (28, 30) of the hinge portion (27, 29). The door (25, 26) includes a left door (25) and a right door (26), and the hinge of the hinge portion (27) for the left door (25). The axis (L1) of the shaft (28) is orthogonal to the axis (L2) of the hinge shaft (30) of the hinge portion (29) for the right door (26).

  According to a third aspect of the present invention, the hinge shaft (30) of the hinge portion (29) of the door provided on the rear side of the left door (25) and the right door (26) is the rear side. The entrance (ER) opened by the door provided on the door is inclined so as to extend rearward as it goes to the opening side.

  According to a fourth aspect of the present invention, in the opened state of the left door (25) and the right door (26), the center of the passenger seat (2) disposed on the side of the left door (25) ( C1) faces upward through the entrance (EL) opened by the left door (25), and the center (C2) of the passenger seat (3) disposed on the side of the right door (26) It faces upwards through the boarding opening (ER) opened by the right door (26).

In the first aspect of the present invention, even when the boarding opening that is opened and closed by the door is formed large on the side of the occupant, the hinge portion is located above the occupant's head or from the direction in which the occupant gets on or gets off in the vehicle width direction. Extending the door in a range not far away from the hinge part in the hinge axial direction of the hinge part while separating the door so that the center of gravity of the door is not greatly decentered from the hinge part, so that the door can be opened and closed suitably by the door Can do. Thereby, the comfort of boarding / alighting can be suitably ensured.
Moreover, when extending a door ahead from a hinge part, it becomes easy to suppress the influence which the hinge part of a door and this support member have on front visibility. Moreover, it becomes easy for a passenger | crew to get in a vehicle from the front because a door opens from the front side.
The present invention can be used particularly effectively in a small vehicle in which the arrangement of the hinge portion is restricted.

In the invention according to claim 2, even when the boarding opening that is opened and closed by the door is formed large on the side of the occupant, the hinge portion is located above the occupant's head or from the direction in which the occupant gets on or gets off in the vehicle width direction. Extending the door in a range not far away from the hinge part in the hinge axial direction of the hinge part while separating the door so that the center of gravity of the door is not greatly decentered from the hinge part, so that the door can be opened and closed suitably by the door Can do. Thereby, the comfort of boarding / alighting can be suitably ensured. In addition, the left and right doors are efficiently provided, and the vehicle can be easily made compact.

  According to the third aspect of the present invention, when the door is extended forward from the hinge portion, the door is opened from the front side, so that the passenger can easily get into the vehicle from the front.

  According to the fourth aspect of the present invention, the overhead space of the occupant spreads upward when the door is open, and a suitable comfort for getting on and off can be ensured.
