Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a panel manufacturing method for a truck bed .
[0002]
[Prior art]
FIG. 3 shows an example of a wing body type truck bed. This is because the front wall 4 is erected along the rear surface of the cab 3 at the front end of the floor 2 of the bed 1. A rear gate frame 6 to which a double door type rear door 5 is attached is erected at the rear end of the floor 2 of the floor 2, and a tilt 7 is provided at both left and right ends of the floor 2 of the loading platform 1 so as to be openable and closable. A pair of left and right winglows 8 covering the upper surface and side surfaces between the rear gate frame 6 and the rear gate frame 6 are configured to be openable and closable by the operation of the hydraulic cylinder 9. There is also a so-called full wing type in which there is no tilt 7 and the lower ends of the left and right wing grooves 8 extend to the left and right ends of the floor 2 of the loading platform 1, respectively.
[0003]
In the conventional case, as shown in FIG. 4, the wingruff 8 is generally cut and pasted on the surface of the roof frame 10 with a roof outer plate 11 made of a thin aluminum sheet wound in a roll shape. Thus, the roof panel 12 is formed, and the side panel 15 is formed on the surface of the side frame 13 by pasting a plurality of corrugated outer plates 14 formed by processing a thin aluminum plate into a corrugated plate, The roof panel 12 and the side panel 15 are formed to be connected at a substantially right angle so as to have an L-shaped cross section by a corner rail 16 formed by extruding aluminum.
[0004]
In addition, as a structure of the wing part in the wing body type truck loading platform, there is, for example, one disclosed in Patent Document 1 in addition to the structure shown in FIG.

[Problems to be solved by the invention]
However, in the conventional wingroove 8 as shown in FIG. 4, the roof skin 12 and the corrugated skin 14 are individually attached to the roof frame 10 and the side frame 13, respectively. In this case, in particular, a large number of rivets are required for attaching the corrugated outer plate 14 to the side frame 13, and the roof panel 12 and the side panel 15 respectively formed Therefore, the number of parts is large, and it takes time and labor to assemble, resulting in an increase in the number of assembly steps and an increase in cost.
[0007]
Further, the corrugated outer plate 14 in the side panel 15 is corrugated to improve the appearance, but this processing cost is one of the factors that increase the overall cost.
[0008]
In view of the such circumstances, it is possible to reduce the number of parts member such as a corner rail connecting the roof panels and the side panels as required, the number of assembly steps and methods panel production bed truck to obtain working to reduce the cost Is to provide.
[0009]
[Means for Solving the Problems]
The present invention is a panel manufacturing method for a truck bed that is bent at a substantially right angle so as to have an L-shaped cross section,
One end of the outer plate is fixed to one end away from the corner of the frame forming the skeleton of the L-shaped cross-section panel, and the other end of the outer plate is pulled to apply tension, and the outer plate is attached along the bending surface of the frame. The invention relates to a panel manufacturing method for a truck bed characterized by sticking a plate .
[0010]
According to the above means, the following operation can be obtained.
[0011]
As described above, one end of the outer plate is fixed to one end away from the corner of the frame forming the skeleton of the L-shaped cross-section panel, and the other end of the outer plate is pulled to apply tension, and the bent surface of the frame If the outer plate is pasted along, the two panels in the L-shaped cross section need not be individually formed, and the panels need not be connected using a member such as a corner rail. As a result, the number of parts is small, and labor and time are not required for assembling, and an increase in the number of assembling steps and an increase in cost can be avoided.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0016]
FIGS. 1 and 2 are examples of embodiments for carrying out the present invention. In the drawings, the parts denoted by the same reference numerals as those in FIGS. 3 and 4 represent the same thing and form the skeleton of the L-shaped cross-section panel. A frame 17 is formed in advance, and one end of the outer plate 18 is fixed to one end (lower end) away from the corner of the frame 17 by a connecting means 19 such as a rivet or welding. The outer plate 18 is attached along the bent surface of the frame 17 while the operator pulls the end (upper end) to apply tension, thereby forming the win groove 8.
[0017]
In the case of the illustrated example, the other end of the outer plate 18 is fixed to the other end away from the corner of the frame 17 by a connecting means 19 such as a rivet or welding, similar to the one end side, An intermediate portion of the outer plate 18 along the bent surface of the frame 17 is fixed by being filled with an adhesive or the like in order to prevent intrusion of rainwater or the like.
[0018]
As the outer plate 18, a thin aluminum plate having good workability such as bending is suitable. However, in consideration of cost and environmental aspects, recycled aluminum cans are used. .
[0019]
Next, the operation of the illustrated example will be described.
[0020]
As described above, when the wingroove 8 is formed from the frame 17 that forms the skeleton of the L-shaped cross section panel and the outer plate 18 that is attached while applying tension along the bending surface of the frame 17, FIG. Unlike the conventional wingroove 8 as described above, it is necessary to form the roof panel 12 and the side panel 15 by respectively attaching the roof skin 11 and the corrugated skin 14 to the roof frame 10 and the side frame 13 respectively. In addition, a large number of rivets are not required for attaching the corrugated outer plate 14 to the side frame 13, and the formed roof panel 12 and the side panel 15 are connected using the corner rails 16. There is no need to do anything. As a result, the number of parts is small, and it takes less time and labor to assemble, resulting in an increase in assembly man-hours. Cost is avoided.
[0021]
Further, the outer plate 18 is attached to the frame 17 with tension applied, and since the surface is kept smooth without any distortion, the corrugated outer surface subjected to corrugated processing as in the prior art is used. Even if the plate 14 is not used, there is no concern that the appearance will deteriorate, and the cost for this processing cost can be reduced.
[0022]
Furthermore, since the outer plate 18 is made of a recycled aluminum can, it is inexpensive and useful for environmental protection.
[0023]
In this way, a member such as a corner rail 16 that connects the roof panel 12 and the side panel 15 is not required, the number of parts can be reduced, and the number of assembling steps and costs can be reduced.
[0024]
In addition, the panel manufacturing method of the truck bed according to the present invention is not limited to the above-described illustrated example. In a normal truck bed other than the wing body type, it is bent at a substantially right angle so as to have an L-shaped cross section. Of course, various modifications can be made without departing from the gist of the present invention, such as being applicable to a panel that is not openable such as the win groove 8.
[0025]
【The invention's effect】
As described above, according to the panel manufacturing method for a truck bed according to the present invention, it is possible to reduce the number of parts by eliminating the need for a member such as a corner rail that connects the roof panel and the side panel, and to reduce the number of assembly steps and costs. An excellent effect can be achieved.
