Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a tilt structure of a lorry.

[0002]

2. Description of the Related Art Panels called "orients" that can be opened and closed are provided at the sides and rear of a luggage carrier of a lorry. When loading and unloading luggage, this tilt is normally open until it hangs vertically. Recently, the tilt has also been made extremely lightweight by using a hollow material such as aluminum, and accordingly, a very tall tilt called a so-called tall tilt has come to be attached.

However, if the tilt is too tall, the tip of the tilt can catch on the ground when the tilt is opened. Since it is necessary to move the vehicle a little when loading and unloading luggage, it is impossible to move if Aori is on the ground. For this reason, recently, it is seen that the tilt is made into a two-tiered upper and lower, but the joint structure is such that the upper tilt is inserted from above, so this plug must be removed to remove the upper tilt. No, it is a lot of work.

Therefore, Japanese Patent Publication No. Sho 60-052007 proposes a two-stage tilt mechanism, of which the upper tilt mechanism is hinged so that the upper and lower ends can be opened. There is.

[0005]

However, in this structure, since the upper and lower tilts are not always connected to each other, even if the upper tilt is rotated at the upper end, the presence of the load does not affect the load. It may get in the way of being dropped. The present invention solves such a problem. The point is that the upper tilt and the lower tilt are always connected so that they can rotate.

[0006]

SUMMARY OF THE INVENTION Under the above problems, according to the present invention, the tilt can be rotated outward with respect to the loading platform to have substantially the same thickness.
In the tilting structure of a freight car divided into two stages, the lower tilting and the upper tilting, the supporting plate has a rotating shaft at both ends, and the two rotating plates are rotatably fitted to the rotating shafts. Using a biaxial hinge consisting of a moving plate, insert a support plate of approximately the same thickness as each tilt between the end faces of the upper and lower tilts, and rotate the outer surface of the upper tilt to the outer turning plate.
In addition, the inside of the lower tilt is fixed to the inner rotating plate, and the upper tilt can be bent almost parallel to the inside and the outside of the lower tilt. provide.

According to the present invention, by taking the above means, if the upper end of the upper tilt connected to the tilt (lower tilt) is opened and hung down, the upper tilt can be hinged. By folding back at the part of, the overall length is shortened and the situation where it can be used is avoided. The operation at this time can be performed by one person because the upper tilt is simply folded back.

On the other hand, when the tilt (lower tilt) is raised, if it is too tall, the upper tilt may be folded back at the hinge portion. The upper tilt can be folded back inside or outside the lower tilt depending on the situation. The operation at this time can be done by one person because only the upper tilt is folded back.

Further, according to the present invention, in the above means, the back of the upper tilt is made lower than that of the lower tilt, the upper tilt and the lower tilt are divided into front and rear, and the upper tilt of each of the front and rear is divided into the lower tilt. It provides a means that can be folded inward and outward.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 is a side view of a large-sized freight vehicle to which the present invention is applied, and FIG. 2 is a sectional view taken along line AA of FIG.
The cargo bed section of a lorry is provided with upper and lower two-stage tilts composed of an upper tilt 12 and a lower tilt 14 on the sides and rear of the horizontal cargo bed 10.

In the tilt of this example, a pillar 16 is erected (removable) at the center of the cargo bed in the front-rear direction, and each tilt 12 and 14 is divided in the front-rear direction with the pillar 16 as a boundary. There is something. Of these, the lower tilt 12 has its lower end connected to the end of the cargo bed 10 by a hinge 18, and the lower tilt 12 is 180 ° centered on the hinge 18.
It rotates and hangs downward.

By the way, in the present invention, the lower end of the upper tilt 14 is always connected to the upper end of the lower tilt 12 by the hinge 20. Thus, this hinge 20 has a structure described later, whereby the upper tilt 12 can be folded back inside the lower tilt 14 and outside substantially parallel to each other.

When the tilts 12 and 14 are erected, they can be fixed to the side surface portion 22 of the vehicle or the pillar 16 described above. Specifically, each tilt 12 and 14
A fixing plate 24 having a hole notched upward is attached to a side end of the hook, and the hole is engaged with a hook 26 projecting from the side surface portion 22 or the pillar 16, and a fixing metal fitting 28 is attached from above. Although the details are already known, detailed description thereof is omitted here.

FIG. 3 is a cross-sectional view showing the mounting of the hinge 20 described above. In order to achieve the above-mentioned function,
The hinge 20 is composed of a single support plate 34 having rotating shafts 30 and 32 at both ends, and two rotating plates 36 and 38 rotatably fitted to the rotating shafts 30 and 32. It has a biaxial hinge structure.

Then, the support plate 34 is moved downwardly by the tilt 1
2 and the rotating end plates 36 and 38 are not fixed to the joint end faces of the upper and lower tilts 14 (if necessary, a groove corresponding to the plate thickness is formed in both or one of them), and the rotating plates 36 and 38 are attached to the outer surfaces of the lower tilt 12 and the upper tilt 14. Alternatively, it is fixed to the inner surface with bolts or the like.

A plurality of hinges 20 are used at a predetermined interval, but at this time, it is preferable that the surfaces on which the rotating plates 36, 38 are abutted are staggered. According to this hinge 20, when the upper tilt 14 is folded back with respect to the lower tilt 12, the relative posture of the upper tilt 14 with respect to the lower tilt 12 becomes the same inside and outside, so that such a usage is possible.

FIG. 4 is a side view showing a state in which the lower tilt 12 is hung vertically with respect to the luggage carrier 10. In this state, when the upper tilt 14 is left as it is, the upper tilt 14 is lifted to the ground. Fold 14 around the hinge 20 outward.

By the way, at this time, since it is necessary to fix the upper tilt 14 in this posture, the fixing plate 24 described above is used.
It suffices to screw the bolt 40 or the like into the side surface portion 22 or the pillar 16 using the above. Since the place where the bolt 40 is inserted is determined, it is sufficient to preliminarily form a screw hole or the like at that place.

FIG. 5 is a side view showing another method of this fixing, but when a rotatable fixing tool 42 is attached to a predetermined position of the side surface portion 22 or the pillar 16 and the upper tilt 14 is folded back. The fixing tool 42 is rotated and locked to the fixing plate 24. It has the advantage that it can be operated with one touch.

FIG. 6 is a side view showing a state in which the lower tilt 12 is erected and only the upper tilt 14 is folded back, but it may be better to tilt the upper tilt 14 depending on the situation such as the packing condition. In such a case, the upper tilt 14 is turned around the hinge 20 and tilted.

In this case, the upper tilt 14 is the lower tilt 1.
Can be folded inside or outside of 2. When the upper tilt 14 is folded back inside the lower tilt 12, it is safe because it is not from the width of the vehicle body, and when it is folded back outside, the cargo space of the loading platform 10 is not reduced. From this, etc.
The height of 4 is preferably lower than that of the lower tilt 12.

In this case as well, it is preferable that the upper tilt 14 is fixed, so that the fixing plate 24 or the like may be used to appropriately fix the upper tilt 14 through bolts or the like.
However, the upper tilt 14 is placed inside the lower tilt 12, that is,
When folded back to the side of the luggage carrier 10, a fixing structure may not be necessary.

The example of the present invention has been described above.
The present invention is not limited to these, and is carried out in various modified modes. For example, there is a single piece of a lorry that is not divided into front and rear, and its material is not limited to aluminum, but there are metal plates, wood boards, etc. Furthermore, the structure for fixing the stile is also described above. The present invention can be applied to all of these, although there are some which do not depend on the fixing plate or the fixing fitting. Further, the present invention can be applied to the rear tilt provided on the rear side of the luggage carrier.

[0024]

As described above, according to the present invention, when the lower tilt is opened and hung down, if the upper end of the upper tilt connected to the lower tilt is caught on the ground, the upper tilt is removed at the hinge portion. By turning it back toward you, the overall length will be shorter and you will not be able to use it. In other words, the height of the tilt can be made higher than ever.

On the other hand, when the lower tilt is raised, if the upper tilt is too tall, it can be folded back to reduce the overall height. At this time, it is convenient that the upper tilt can be folded inside or outside the lower tilt. Thus, these operations can be performed by one person because they are simply folded back.
