Description

[Detailed description of the invention] The present invention relates to a ventilation structure for the door sill of a ventilated container, and is characterized in that the ventilation structure is constructed in the bottom door sill, preventing rainwater from entering at all, and increasing the amount of ventilation. It is something to do.

Ventilated containers are used to transport breathing cargo such as fruits, vegetables, and grains that do not need to be refrigerated. Conventionally, they are constructed with vents installed in the top and bottom sight rails at the top and bottom of the side panels. was.

The present invention can be used in combination with the conventional ventilation structure described above to increase the amount of ventilation.

Generally, a container includes a floor assembly 12, sidewall assemblies 13 on both sides thereof, a front assembly 14 on one end, and a door sill 15 and a door 16 on the other end, as shown in the first drawing.
and a roof assembly 17 mounted above them.

The present invention provides a ventilation structure in the bottom door sill, which was conventionally considered structurally impossible.

One embodiment will be described in detail below with reference to the drawings.

In FIGS. 2 and 3, 1 is a bottom door sill, which is composed of an outer material 2 and an inner material 3.

In the present invention, an extension part 3a is provided by extending the upper side of the inner material 3 inward, and a suitable number of ventilation holes 4 are provided in the extension part 3a.

Furthermore, a channel material 5 having a vent 6 provided at a position shifted from the vent 4 is attached by screws 7 to the upper surface of the vent 4 of the extension 3a.

FIG. 4 shows the positional relationship between the vent hole 4 of the extension part 3a and the vent hole 6 of the channel material 5.

That is, the vents 4 and 6 are arranged so that they are not in the same position above and below to prevent rainwater from entering the interior.

Further, a floor plate 8 is placed on the upper end of the extension 3a and fixed with screws 9.

In the figure, 10 is a door sill material provided below the door 16, and 11 is a reinforcing bracket for the extension portion 3a.

In the present invention, the channel material 5 can be attached by welding, but in that case, it is difficult to paint the inside (especially after welding), and rust cannot be prevented. Furthermore, it is also difficult to clean when dirt and the like accumulate inside.

Therefore, it is preferable that the channel material 5 be attached by screws 7 and made detachable, as in the embodiment shown in the drawings.

The present invention with the above configuration can provide a ventilation structure in the bottom door sill, which was conventionally considered difficult to install due to structural reasons.
Even in that case, there is no intrusion of rain and ice, and the effect of increasing the amount of ventilation can be obtained.
