Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door device.

[0002]

2. Description of the Related Art As a vehicle door device, there is known a parallel link type in which a door is supported on a vehicle body side through a plurality of links so as to move in parallel between a closed position for closing an entrance / exit and a rear open position. (Japanese Utility Model Publication No. 7-36820, etc.).

[0003]

By the way, in a truck or the like, when the parallel link type is adopted for the side door of the cab, the stroke to the rear of the door is restricted in order to avoid interference with the rear body behind the cab. Sometimes.

Therefore, as shown in FIG. 9, the swinging out of the side door 1 toward the side of the vehicle body is performed so that the entrance / exit 2
It is possible to secure the door opening of the. Is a parallel link that supports the side door 1 of the truck cab 3 so as to be openable and closable, and these are stored along the inside of the entrance 2 when the door 1 is closed.

However, since the open position of the door 1 is separated from the entrance / exit 2, the occupant does not reach the handle 5 of the door 1 unless the occupant extends his / her upper body as shown in the drawing, and it is very difficult to close the door 1. In addition, there is a problem in that there is a risk of falling from the entrance / exit 2 because an unstable posture of leaning out is forced.

The present invention aims to solve such problems.

[0007]

According to a first aspect of the invention, in a door device for supporting a door of a vehicle on a vehicle body side so as to be openable and closable via a parallel link mechanism, at least one of a plurality of links forming the parallel link mechanism. Is installed between the lower part of the door and the vehicle body side, and a handle is provided on this link.

According to a second aspect of the present invention, in a door device for supporting a vehicle door on the vehicle body side so as to be openable and closable via a parallel link mechanism, at least one of a plurality of links forming the parallel link mechanism is provided on the lower side of the door and the vehicle body side. And a door trim provided with a handle at the lower part of the door via the link so as to be opened and closed.

[0009]

According to the first aspect of the invention, since the handle is located at the link extending between the lower portion of the door and the vehicle body side at the open position of the door, the door can be easily closed by putting the hand on the handle. You can Even when the open position of the door is away from the vehicle body, if the handle of the link is arranged on the passenger compartment side, the door can be easily closed without leaning out and reaching for the vehicle.

According to the second invention, when the door is opened, the door trim is opened from the lower portion of the door to the vehicle body side in association with the link. Therefore, in the open position of the door, the door trim rises from the lower part of the door toward the vehicle body at a predetermined opening, so you can easily put your hand on the handle of the door trim and move the door easily without leaning outside. Can be closed to. Since the link is located on the back side of the door trim, the link can be stored neatly inside the door covered by the door trim when the door is closed.

1 shows an embodiment applied to a side door of a truck cab. Side doors 10 on both sides of the cab 11 have a parallel link mechanism 12 on the side of the cab 11.
Supported through. Reference numeral 13 is an upper link that forms a parallel link mechanism 12 together with a lower link 14 which will be described later.
It is connected by a pin via a and 18b so as to be freely rotatable in the horizontal direction.

The lower door portion 16 is supported on the cab 11 side by upper and lower lower links 14. A stay 18 is attached to a predetermined position on the side of the cab 11, and both ends of each lower link 14 project to the entrance 17 from the rear.
The tip end and the lower portion of the door 16 are rotatably connected in the horizontal direction through hinges 14a and 14b. 16 lower door
Is trimmed with a door trim 20, and a trim portion 20a having a handle 21 on its upper edge is a fixed side door trim 2.
It is formed separately from 0b, and the lower link 14 is attached to the lower part 16 of the door.
It can be opened and closed via.

In order to prevent the lower link 14 from hitting the rear edge of the entrance / exit 17 when the door 10 is opened, the lower link 14 supporting the back side of the trim portion 20a is connected to the rear edge of the entrance / exit 17 as shown in FIG. A stopper rubber 22 that regulates the opening degree of the door 10 is provided between them. The door lower portion 16 is provided with a door pocket that receives the window glass 23 of the sash 15 (see FIG. 6).

With such a structure, when the side door 10 is opened, the upper link 13 and the lower link 14 rotate outward from the entrance / exit 17 and the parallel link is brought to the open position where the door 10 is swung to the outside rear of the cab 11. The mechanism 12 is translated via the fulcrums a to d. Along with this, the trim portion 20 a including the handle 21 is opened from the lower door portion 16 to the cab 11 side together with the lower link 14.

Therefore, in the open position of the door 10,
Since the trim portion 20a approaches the cab 11 side from the door lower portion 16, without leaning out of the vehicle,
As shown in FIG. 7, the door can be easily closed by hanging the hand on the handle 21 of the trim portion 20a in a comfortable posture.

When the side door 10 is closed, the upper link 13 is stored at the upper edge of the doorway 17 covered by the door 10. As shown in FIG. 6, the lower link can be stored neatly on the back side of the trim portion 20a that forms the interior surface that is continuous with the fixed door trim 20b at the closed position of the door 10.

Although not shown as another embodiment,
A handle may be directly provided on the lower link 14 forming the parallel link mechanism 12. In that case, since the entire trim 20 is fixed to the door lower portion 16, the lower link 14 does not need to secure the supportability of the trim portion 20a, and can be omitted as one. At the lower part of the door, the handle 21a as shown in FIG.
You may project in the plane part of 0a.

[0018]

According to the first aspect of the present invention, in a door device for supporting a vehicle door on the vehicle body side so as to be openable and closable via a parallel link mechanism, at least one of a plurality of links forming the parallel link mechanism is a door. Since the link is installed between the lower part and the vehicle body side, and a handle is provided on this link, even if the door open position is away from the vehicle body, it is possible to easily perform the door closing operation without leaning out of the vehicle. It will be possible.

According to the second aspect of the present invention, in the door device for supporting the door of the vehicle on the vehicle body side so as to be openable and closable via the parallel link mechanism, at least one of the plurality of links forming the parallel link mechanism is a door lower part. In addition to being installed between the vehicle body side and the door trim, which is provided with a handle at the door lower part via this link so that it can be opened and closed, the door trim from the door lower part to the vehicle body side at a predetermined opening at the door open position. Since it stands up, it is possible to easily close the door by hanging the hand on the handle of the door trim in a comfortable posture without leaning out of the vehicle. Further, since the link is located on the back side of the door trim, the link can be stored neatly inside the door covered by the door trim at the closed position of the door.
