Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a truck and, more particularly, to a rear gate structure for engaging one end of a road plate.

[0002]

2. Description of the Related Art As shown in FIG. 6, a lorry is constructed such that a rear gate a is tilted down and one end of a road plate b is engaged with an upper end of the rear gate a so that the road plate b is erected between the carrier and the ground. There is something that I did. FIG. 3 shows a cross section of the rear gate of such a truck. In this rear gate a,
The upper surface of the lower rail c (when the rear gate a is lowered) is depressed over the entire width, and one end of a hinge e is welded to the inner surface of the depressed portion d. Then, one end of the road plate b is engaged with the depressed portion d of the lower rail c.

[0003]

However, the rear gate a having such a structure has the following disadvantages. i) Since the depression d of the lower rail c is formed by the roll forming method, the installation cost increases and the cost increases. ii) Since one end of the hinge e is welded to the inner surface of the recess d, the work is troublesome and the number of steps is increased. iii) The closed section of the lower rail c is smaller than that of the specification shown in FIG. 4 which does not use the road plate b, which is disadvantageous in strength. iv) Since the openings on both sides of the lower rail c are closed by the gate pillar f as shown in FIG. 5, when the rear gate a is knocked down and the car is washed, muddy water accumulates on the lower rail c and causes corrosion. .

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve such a drawback, and the gist of the invention is to reduce the load.
One end is pivotally supported at the rear edge of the bed, and the one end is
Along the rear edge of the loading floor and from a bag-shaped closed section.
A rear gate with a lower rail
On both sides, a gate closing both ends of the bag-shaped closed cross section is provided.
A gate pillar is provided, and
Rear reinforcement for agate reinforcement
Provided above and below the gate, and fell the rear gate down
In the state, the cross section is almost U-shaped at the upper end of the rear gate
A truck having a substantially L-shaped cross-section on the lower rail of the rear gate, wherein the lower rail is provided with a lower portion of the trailer.
With the rear gate down,
To the rear of the lower rail.
The locking member forms the locking portion having a substantially U-shaped cross section.
And a fold at the rear end of the locking member
And the intersection of the engagement member and the reinforcement
Reinforcement opens a gap at the locking member
A lorry characterized by having a notch penetrating through it .

[0005]

1 and 2 show a rear gate of a truck according to the present invention. In FIG. 1, reference numeral 1 denotes a rear gate, which is provided with an upper rail 2 and a lower rail 3 at both upper and lower ends thereof. Then, the lower rail 3, times the trailing edge of the deck floor panel 5 <br/> upper surface 3a disposed at one end of the rear gate 1 is bed floor via a hinge 4 in a state where defeated rear gate 1 It is movably connected. In addition, full
It is provided along the rear edge of the lower panel 5 and has a bag-like closed cross section.
L-shaped cross section of the locking member 6 on the lower surface 3b of the lower rail 3 consisting of the Yes and joined by a plug weld, by engaging the engaging portion 7a of Michiban 7 at the distal end of the member 6該道The plate 7 is set. Further, the bottom wall 6 of the locking member 6
2, a hole 6b for plug welding and a notch 6c for passing the reinforcement 8 are provided at a predetermined interval as shown in FIG. 2, and a folded portion 6e is provided at the tip of the side wall 6d. Is provided.

Since both ends of the locking member 6 protrude rearward from the gate pillar 9 (see FIG. 2), muddy water at the time of washing the vehicle and the locking member 6 provided in the notch 6c and the leaning member 6 are leaned.
It does not flow out of the gap of the force 8 to the outside and remains in the locking member 6. Note that the locking member 6 is not limited to such a shape, and any other shape having a function of locking the road plate 7 can be employed as appropriate.

[0007]

According to the present invention, the upper surface of the lower rail of the rear gate does not need to be depressed as in the prior art.
The following effects can be obtained. L-shaped locking section
Since a material is added, a U-shaped locking portion is formed.
This eliminates the need for roll forming equipment, thus reducing equipment costs.
Is reduced. Also, the locking member is behind the gate pillar
The rear gate so that it is mounted
When the car is washed, the muddy water that collects in the U-shaped
Can be discharged from the department. Reinforcement opens gaps
Notches that penetrate through the
Muddy water can be drained from the gap. Therefore,
The drainage of the U-shaped locking part is improved, and the water pool of the locking part is
Prevents rust, which causes rust. It is easier to weld the hinge to the lower rail, reducing man-hours. The closed cross section of the lower rail is increased, which is advantageous in strength.
