Description

Description: TECHNICAL FIELD The present invention relates to a truck rear gate structure.

<Conventional Technology> As a conventional truck bed structure, for example, there is one shown in FIG. 5 (1989 Nissan Motor Co., Ltd. SE
RVICE MANUAL No.SM9E-OD21UO Page BF-7).

In the figure, reference numeral 1 denotes a side panel, which stands on both left and right edges of a carrier 3 of a rear body 2 along the longitudinal direction of the vehicle body. A rear gate 4 is attached to the rearmost part of the carrier 3 in the vehicle width direction. That is, the hinge pins 5 fixed to the lower ends of the left and right sides of the rear gate 4 are rotatably attached to the lower end of the rear inner surface 1a of the side panel 1.
Then, near the upper end of the inner surface 1a at the rearmost part of the side panel 1,
One end (side panel-side rotation fulcrum 6a) of the link arm 6 for limiting the opening of the rear gate 4 is rotatably mounted, and the other end (rear gate-side rotation fulcrum 6b) of the link arm 6 is at the upper end of the right and left sides of the rear gate 4. It is rotatably mounted in the vicinity. Further, a folding hinge 6c is provided at the center of the link arm 6, so that the link arm 6 can be folded into two. That is, when the rear gate 4 is closed, the link arm 6 is folded and the rear gate 4 is closed.
In a fully opened state where the rear arm 4 is horizontal, the link arm 6 extends straight and prevents the rear gate 4 from opening any more. Therefore, when the rear gate 4 is fully opened, the inner side surface of the rear gate 4 forms the same plane as the upper surface of the carrier 3.

<Problems to be Solved by the Invention> However, in such a conventional technique, when the rear gate 4 is fully opened, the rear gate 4 lies over the license plate 7 over the entire width of the vehicle. 7 cannot be confirmed from behind. For this reason, when traveling with luggage longer than the length of the bed 3, the operation of removing the rear gate 4 is required, which is very troublesome.

The present invention has been made by paying attention to such conventional technology, and when traveling with loaded luggage longer than the loading platform, luggage can be loaded without removing the rear gate,
Another object of the present invention is to provide a truck bed structure that does not impair the visibility of the license plate.

<Means for Solving the Problems> In order to achieve the above object, a truck bed structure according to the present invention is provided on a rear inner side surface of a side panel having a constant height that is erected on both right and left sides of the truck. A vertical rail portion is formed over substantially the entire height of the side panel, and a hinge pin projecting from the lower end of each of the left and right sides of the rear gate is slidably engaged with the vertical rail portion, and a projection is provided above the rear inner surface of the side panel. And the rear gate is pivotally opened rearward about a hinge pin positioned at the lower end of the vertical rail portion, and is turned forward around the hinge pin positioned at the upper end of the vertical rail portion. By moving it, it can be placed horizontally on the protrusion.

<Operation> According to the truck bed structure of the present invention, the hinge pins are slidable along the vertical rails. Therefore, even when loading a load longer than the bed, the rear gate can be moved along the vertical rails without removing the rear gate. It can be lifted up and stored horizontally in the protrusion provided above the inner surface of the rearmost part of the side panel. Accordingly, the rearmost portion of the loading platform is opened, and a long-sized package can be loaded.

Further, since the rear gate does not lie above the license plate, even if long luggage is mounted horizontally on the carrier and travels, the visibility from behind the license plate is not impaired.

<Embodiment> A preferred embodiment of the present invention will be described below with reference to FIGS. Here, the same reference numerals are given to portions common to the conventional example, and duplicate description will be omitted.

20 is a vertical rail. The vertical rail 20 has side panels 24
Of the rear gate 21 in a normal truck, the hinge pin 22 which is the rotation fulcrum of the rear track 21 extends upward with its lower end as a lower end, and is formed at least up to the position of the side panel-side rotation fulcrum 23a of the normal link arm 23. ing. A horizontal rail 25 is formed from the upper end of the vertical rail 20 along the upper edge of the side panel 24 and toward the front of the vehicle body horizontally. Vertical and horizontal rails 20, 25
In both cases, an elongated groove is formed on the inner surface 24b of the side panel 24, and a space 27 is formed along the groove between the inner surface 24b and the outer surface 24c of the side panel 24. A projection 28 for mounting the rear gate 21 is provided below the horizontal rail 25.

On the other hand, in a normal use state as shown in FIG. 2, the hinge pin 22 is located at the lowermost end of the vertical rail 20, and the rear gate 21 can be opened rearward and pivotable about the hinge pin 22. Further, the hinge pin 22 is slidably attached to the vertical rail 20.

Also, the rotation support point 23b on the rear gate side of the link arm 23
Are mounted near the upper ends of the left and right sides of the rear gate 21. The side panel-side rotation fulcrum 23a of the link arm 23 is slidably mounted on the horizontal rail 25, but in a normal use state, as shown in FIG.
In a state fitted in a concave portion 29 provided below the rear end of the vicinity of the rear end 25, only a rotational movement is possible. Furthermore, the side panel-side rotation fulcrum 23a of the link arm 23
Has an assist spring 30 that biases the force toward the front of the vehicle.
Is connected. That is, the assist spring 30 is provided between the inner side surface 24b and the outer side surface 24c of the side panel 24.
The front end portion is fixed to the side panel 24, and the rear end portion is fixed to the side panel-side rotation fulcrum 23a of the link arm 23. Therefore, the assist spring 30 always tries to move the link arm 23 forward.

Next, the use state will be described with reference to FIGS. 3 (A) to 3 (D).

FIG. 3A shows a state in which the rear gate 21 is closed.
This is the same as in a normal use state. In this state, the link arm 23 is in a state of being bent by the folding hinge 23c at the center.

FIG. 3B shows a state in which the rear gate 21 is fully opened, which is exactly the same as a normal use state. In this state, the rear gate 21 is opened rearward while the hinge pin 22 is located at the lower end of the vertical rail 20 from the state of FIG. 3A (see FIG. 2).

FIG. 3 (C) shows that the hinge pin 22 is connected to the vertical rail 20 while the rear gate 21 is rotated forward to mount a long object.
Shows a state of being moved upward along the arrow. In this state, the rotation support 23
a is taken out from the concave portion 29 at the rear end of the horizontal rail 25 onto the horizontal rail 25, and is moved forward by the force of the assist spring 30.

FIG. 3 (D) shows a state in which the hinge pin 22 is moved from the vertical rail 20 to the horizontal rail 25, and is fitted and fixed in the concave portion 29 at the rear of the horizontal rail 25. Then, the rear gate 21 is further rotated to the front side, and is finally stored in a state shown by a two-dot chain line in the figure. That is, when the long object is mounted, the hinge pin 22 is
And can rotate only. The link arm 23 is pulled forward by the restoring force of the assist spring 30. Furthermore, the rear gate 21 has a side panel
It is placed horizontally on a projection 28 provided above the rear inner surface of 24 (see FIG. 1).

In the truck bed structure of the present invention configured as described above, since the hinge pin 22 and the side panel-side rotation fulcrum 23a of the link arm 23 are slidable along the vertical and horizontal rails 20, 25, the rear gate 21 is removed. It can be stored above the side panel 24 without the need. Therefore, when the vehicle travels with luggage longer than the length of the bed 3, the rear gate 21 does not impair the visibility of the license plate 7 from behind. Further, it is possible to eliminate a very troublesome work of removing the rear gate 21.

In the above-described embodiment, the horizontal rail 25 is provided on the upper portion of the side panel 24 because the track is provided with the link arm 23. The assist spring 30 can be omitted.

Further, although the plate-shaped protrusion 28 has been described as an example, a rod-shaped protrusion may be used as long as the rear gate 21 can be placed horizontally.

<Effect of the Invention> The truck bed structure according to the present invention has the contents as described above, and when loading luggage longer than the bed, it is stored horizontally at the top of the side panel without removing the rear gate. Therefore, the very troublesome work of removing the rear gate can be eliminated.

Further, when the long luggage is mounted horizontally on the luggage carrier and travels, the rear gate does not lie above the license plate as in the related art, so that the rear gate does not impair the visibility from behind the license plate.
