[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luggage box of a lorry in which a rear door of the luggage box opens sideways around one side edge.

[0002]

2. Description of the Related Art Conventionally, a rear door has been configured to be able to open laterally to the side of a vehicle body around a vertical axis via a hinge,
A door comprising an engagement pin provided on each of the left and right sides of the rear door, and a securing member provided at the rear end of the side wall corresponding to the engagement pin and configured to be detachable from the engagement pin. There is provided a cargo box of a lorry in which an opening / closing device is provided so as to fix and release the opening and closing of the rear door, and the tip of the engaging pin is formed in a flange shape, and the side wall falls down to the side. This is supported by the tip of the engaging pin formed in a flange shape, thereby suppressing the side wall from falling down.

[0003]

However, the one which suppresses the side wall from falling down at the tip of the engagement pin formed in a flange shape is very effective in suppressing the side wall from falling down. Since the tip of the flange-shaped engaging pin supports the lashing metal on the flange surface, the tip of the engaging pin and the lashing metal are closed when the rear door is opened. There was a problem that the rear fan door could not be opened smoothly due to the gnawing shape. This is remarkable in the door opening / closing device on the side where the hinge is provided.

[0004]

According to the present invention, there is provided a cargo box for a truck, in which a rear door of a cargo box having a side wall and a front wall standing upright with respect to a bottom wall is provided around a vertical axis via a hinge. An engaging pin is provided on each of the left and right sides of the rear door and is provided at a rear end of the side wall corresponding to the engaging pin. A door opening / closing device comprising a freely-arranged lashing metal fitting is provided on a cargo box of a lorry in which the opening and closing of the rear door is freely fixed and released. The engagement pin of the device is extended so as to protrude from the side wall in a state where the engagement pin is locked to the lashing fitting.

[0005]

The engagement pin of the door opening / closing device on the side where the hinge is arranged is extended so as to protrude from the side wall while being locked by the lashing fitting, thereby suppressing the side wall from falling down and rearward. Opening the door is smooth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a cargo box of a truck according to the present invention.

In FIG. 1, reference numeral 1 denotes a rear door of a packing box in which a side wall 2 and a front wall (not shown) are erected with respect to a bottom wall, and one side of the rear door 1 and one side thereof. It is configured so that it can be opened laterally sideways around a hinge 3 provided on one side wall 2 corresponding to the portion.

On the upper sides of both sides of the rear door 1, there are provided door opening and closing devices 4, 4 for securing and releasing the opening and closing of the rear door 1.

The door opening / closing device 4 provided with the hinge 3 is provided with an engaging pin horizontally disposed via a bracket 41 on the side of the rear door 1 as shown in FIGS. 4
2 and a securing bracket 43 provided at an upper portion of the rear end of the side wall 2 and detachable from the engaging pin 42.

As shown in FIG. 3, the lashing fitting 43 has a U-shaped receiving opening 44 that opens rearward.
5 and a securing portion 47 formed with a receiving port 46 having the same shape as the receiving port 44 of the receiving device 45 and rotatably fitted into the receiving device 45. Operating rod 4
The engaging pin 42 is disengaged by rotating the securing portion 47 by 8.

The distal end of the engaging pin 42 is extended from the side wall 2 so as to protrude laterally in a state of being locked by the securing metal fitting 43.

Further, the door opening / closing device 4 on the side opposite to the side on which the hinge 3 is provided (the opening side of the rear door 1)
It differs from the above-described door opening / closing device 4 only in that the distal end portion 42a (see FIG. 1) of the engaging pin 42 is formed in a flange shape, and other configurations are the same. The same reference numerals are given to the members and the description is omitted.

The reference numeral 6 in FIG.
Is a securing member provided at the side end on the open side of the vehicle.

In the luggage box of the truck constructed as described above, the rear door 1 is pivoted around the hinge 3 by releasing the securing by the left and right door opening and closing devices 4 and 4 and the securing member 6. It can be opened sideways.

Here, since the tip of the engaging pin 42 of the door opening / closing device 4 on the hinge 3 side is extended so as to protrude sideways from the side wall 2, if the side wall 2 tries to fall to the side. The securing bracket 43 provided on the side wall 2 is supported by the tip of the engaging pin 42 provided on the rear door 1, and the tip of the engaging pin 42 can suppress the fall of the side wall 2. At the same time, even if the side wall 2 falls down, when the rear door 1 is opened, the rear door 1 can be smoothly separated without being bitten when the rear door 1 is opened.
Can be opened smoothly.

The front end portion 42a of the engaging pin 42 of the door opening / closing device 4 on the side opposite to the hinge 3 is formed in a flange shape because the rear door 1 is closed and secured when the door is closed. 2
It is effective in forcibly correcting the fall of the sword.

[0018]

As described above, according to the present invention, the engaging pin of the door opening / closing device on the side where the hinge is arranged is projected from the side wall in a state where it is locked by the lashing fitting. By extending, the fall of the side wall can be suppressed at the tip of the engaging pin, and even if the side wall falls, the rear door can be smoothly opened.
