Description

[Detailed Description of the Invention] The present invention relates to an improvement of the ventilation opening of a box-shaped loading platform of a truck.

Both left and right sides of the box-shaped loading platform 1 of a conventional truck are
As shown in FIGS. 1 to 4, an outer panel 1a and an inner panel 1b formed with a gap 2 from the outer panel 1a.
The outer plate 1a is formed with a large number of reinforcing ribs 4 that extend in parallel in the lateral direction and are equally spaced in the vertical direction. In order to form a ventilation hole on the side surface of the box-shaped loading platform 1 on which such reinforcing ribs 4 are formed, a cutout hole 5, for example, a rectangular cutout hole or a square cutout hole, is formed in the portion of the outer panel 1a where the ventilation hole is to be formed. Alternatively, a cutout hole 5 of another shape is provided, and a ventilation plate 8 having a guide portion 6 protruding to form a downward air intake port 7 is applied from the back side of the outer panel 1a, and the guide portion 6 is The ventilation plate 8 and the outer plate are fixed by brazing or other means with the ventilating plate 8 protruding outward from the cutout hole 5, and the inner plate 1b is placed at a position corresponding to the upper part of the air intake port 7 of the outer plate 1a. Air circulation holes 9 were formed. 3 is the vertical outer panel part between the reinforcing ribs 4, 4.

In the above-mentioned known ventilation hole, the work of forming the cutout hole 5 in the outer panel 1a, the edging work thereof, and the ventilation plate in which the guide portion 6 protruding to form the downward air intake port 7 are formed. It is not only inefficient because it requires complicated steps including the work of forming the ventilation plate 8 and the work of attaching the ventilation plate 8 to the back side of the outer panel 1a.
In addition, during times of heavy wind and rain, rainwater may enter through the ventilation holes along with the wind, enter the cargo compartment through the air circulation holes 9 in the inner panel 1b, or fall and accumulate in the two gaps between the inner and outer panels 1b and 1a. There was money damage.

The present invention forms a ventilation hole by using reinforcing ribs 4, 4 formed on the side surface of the outer panel 1a of the box-shaped loading platform 1 of a truck and extending parallel to the lateral direction, and the work of forming the ventilation hole is extremely simple. A ventilation hole in a truck cargo bed that is not only quick but also looks good, and eliminates the drawbacks of wind and rain entering the cargo compartment and the gap between the outer panel and the inner panel and accumulating. The purpose of this system is to provide an outwardly projecting structure on the side surface of the box-shaped loading platform of a truck, which is formed into a double structure by an outer panel and an inner panel. A part of the outer plate located between the upper chevron reinforcing rib and the lower chevron reinforcing rib among the chevron reinforcing ribs formed to extend in the horizontal direction. By forming a cutting line with the width of the ventilation opening, and cutting both ends of the cutting line upward to form a U-shaped cutting line that reaches the top of the chevron of the upper chevron reinforcing rib, it is connected to the upper part of the lower chevron reinforcing rib. A raised edge and a hanging guide edge that hangs down in parallel with the raised edge forming a ventilation gap to cover and close the gap between the outer plate and the inner plate near the upper edge of the raised edge, and on the inner plate side. Attach a stiffener that extends upward to form a bent edge that bends to the inner plate,
A ventilation opening of a cargo bed for a truck is characterized in that an air circulation opening is formed in an inner plate portion located above the bent edge.

The present invention will be described below with reference to the embodiments shown in the drawings.

At least both sides of the box-shaped loading platform 1 of the truck,
An outer panel 1a is provided on the outside, and a gap 2 is provided inside the outer panel 1a.
It has a double structure in which the inner plate 1b is formed by forming the inner plate 1b.
The above-mentioned outer panel 1a has a large number of parallel chevron-shaped reinforcing ribs 4a that protrude toward the outer surface and extend in the horizontal direction.
4b, 4c, and 4d are formed, and vertical outer plate portions 3 are formed at equal intervals between the chevron-shaped reinforcing ribs. Upper chevron reinforcing rib 4a formed as described above
As shown in FIG. 9, a cutting line with a width l of the desired ventilation opening is formed in the outer panel portion 3 between the lower chevron reinforcing rib 4b and the lower chevron reinforcing rib 4b in the horizontal direction. By cutting both ends of the line upward approximately vertically to form a U-shaped cut line 11 that reaches the chevron top 4a' of the upper chevron-shaped reinforcing rib 4a, the raised edge 3' connected to the upper part of the lower chevron-shaped reinforcing rib 4b and the above-mentioned raised edge 3' are formed. A ventilation gap 7' is formed with the upper edge, and a hanging guide line 12 hanging in parallel is formed. A hanging edge 13b formed on one side of the horizontal edge 13a of the stiffener 13 is fixed to the inner surface of the upright edge 3' in the gap 2 between the outer plate 1a and the inner plate 1b by soldering or other means. The rising edge 13c at the other end of the horizontal edge 13a is fixed to the inside of the inner plate 1b by soldering or other means, and the leading edge of the rising edge 13c is further horizontally bent inward to form a bent edge 13d. do. An air flow opening 14 is provided above the bent edge 13d of the inner plate 1b.

Since the present invention has the above-mentioned structure, there is no need to provide a cutout hole 5, and therefore, the cutout hole 5 does not appear in the ventilation hole of the box-shaped loading platform of the truck as in the conventional case, resulting in a good appearance. Therefore, outside air and inside air are handled by the lower chevron reinforcing rib 4.
Air entering from the ventilation gap 7' between the tapered surface of b and the hanging guide edge 12 is guided by the stiffener 13 and sent into the loading platform from the air circulation opening 14 of the inner plate 1b along the stiffener, and the air inside the loading platform is It is discharged from the ventilation gap by a route opposite to that described above.
Furthermore, the stiffener 13 prevents the rainwater from accumulating in the gap 2 between the outer plate 1a and the inner plate 1b, and the rainwater is guided along the bending line 13d of the stiffener 13, and the rainwater flows through the inner plate 1b.
The air circulation hole 14 provided in the carrier is located above the bent edge 13d, and together with this, the air circulation hole 14 does not intrude into the loading platform 1.

As described above, the present invention allows the work of forming a ventilation plate with a protruding guide portion to form a wind intake, without providing any cut-out holes, and therefore without requiring any edging work. Not only can ventilation holes be formed very simply and efficiently using the reinforcing ribs that have traditionally been formed on box-shaped truck beds without the need to attach them to the back of the outer panel, but it also improves the appearance. Also, rainwater that enters through the ventilation openings is prevented by the stiffener from entering the cargo compartment, and the box-shaped cargo bed of the truck does not enter the gap between the outer and inner panels and accumulate. It has the effect of providing a ventilation hole.
