Abstract

(57) [Summary] (Modified) [Problem] When moving the door to the body side with a wing (roof) or a box-shaped body van or container that opens and closes, the rail mechanism that supports the door moves to the back side. . Also, it is difficult to move the door to the body side because it moves with the wing. A swingable member slide arm is attached to the rear end of a direction changing arm for facilitating the direction change of a door inside a body pillar (gate). The door is attached to the slide in the lateral direction (freely), and the door can move to the side of the vehicle body. Further, the tension arm 2 and the tension spring can be attached and the door 1 can be easily moved to the body side so that the member can be easily swung. In addition, by attaching the door locking mechanism in the direction opposite to the door 1 mounting guide pin, one-touch locking of the door 1 is also possible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a device for moving a door at the rear of a box-shaped body of a freight vehicle, and relates to a box-shaped body such as a van and a container whose body side opens and closes like a wing car. Even if there is, it provides the structure of the mechanism that allows the door to slide and move laterally.

[0002]

2. Description of the Related Art A box-shaped body of a lorry,
As a method of moving the rear door to the body side, as shown in FIG. 7, a sliding hinge 19 for supporting the door on the upper and lower sides of the rear portion of the body, the upper rail 16, and the lower rail 1 are used.
7. Further, the guide 20 is attached, and the configuration of the supporting component when the door 1 is moved to the body side allows the door to be moved to the body side.

[0003]

In the structure of the conventional mechanism, like a wing car, the wing (roof) 13 and the fan 1 are tilted.
In the body that opens and closes 4, when the door 1 is opened, the upper rail 16 and the lower rail 17 that support the door 1 are hidden behind the fan 14 or move with the wings, so the door 1 is moved to the body side. The door cannot be moved because there is no rail to support it.

When the door 1 is automatically moved to the body side, the existing structure of the mechanism for moving the door 1 to the body side in FIG. 7 is difficult to automate because the structure is complicated.

[0005]

In order to achieve the above object, the door is changed by the direction change arm and the slide arm is used when the door is moved to the body side inside the pillar (gate) in FIG. To the body side. In addition, slide rails and slide arms are provided to change the direction of the door and support it so that it can be moved to the body side, allowing the door to slide laterally. In addition, by installing a tension arm that supports the door inside the pillar (gate), the tension arm, which is an obstacle when the door is closed, is slid in the front-back direction of the body. It is possible to rotate and slide, and it is possible to rotate and move the door regardless of opening and closing of the body side like a wing car.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, the present invention supports a door 1 as a structure of a mechanism for supporting the door 1 inside a pillar (gate) 7 at the rear part of the body and converting the direction to move the door 1 to the body side. The mechanism used is the tension arm 2 and the direction changing arm 3 shown in FIGS. Furthermore, the slide arm 6 becomes the main shaft, and the door 1
Tension spring 2 when moving to the body side of
With the structure in which the tension arm 2 is pushed out to the rear of the body by 1 and the direction changing arm 3 and the slide arm 6 can be smoothly converted, the door 1 can be moved to the body side. Further, the slide arm 6 connected to the door 1 supports the door 1, and a slide rail 9 is provided inside the door 1 so that the door 1 can slide laterally, so that the door 1 can be moved to the body side. did.

In FIG. 5, a mechanism for locking the door 1 at the rear portion of the body and the locking mechanism when the door 1 is closed is adopted for the pillar (gate) 7 part, and as a method of fixing the portion corresponding to the front end portion of the door 1,
Door 1 with mechanism consisting of guide pin 24 and lock guide 12
The structure of the door lock mechanism 25 is adopted in the opposite direction to the attachment of the lock pin 24, and the one-touch lock is enabled.

[0008]

According to the present invention described above, there are technical effects as described below. Wing
Even with a body that opens and closes the door 13 and the fan 14, the door 1 is provided by a plurality of arms that support the door 1 inside the pillar (gateway) 7.
Since the vehicle can be easily moved to the body side, the door 1 can be opened and closed even in a place where the vehicle side is narrow. Therefore, when vehicles at terminals of freight vehicles, which have been increasing in number in recent years, are lined up in rows and loaded and unloaded, the door 1 of the present invention is moved to the body side even if the space between the vehicles is narrow. By adopting, it becomes possible to increase the number of rows of freight cars at places such as terminals, and the truck terminal can be effectively utilized.
