Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ventilation hole opening/closing device for a container that facilitates internal ventilation, and is characterized by being able to open and close multiple ventilation holes with a single touch.

[Conventional technology]

Traditionally, so-called dry containers have been used to transport miscellaneous goods and other dry cargo (see Japanese Patent Publication No. 1983-39713).
Ventilated containers (see Japanese Utility Model Publication No. 61-29662) are generally used to transport fresh and respirable cargo such as fruits, vegetables, and grains that do not require refrigeration.

[Problem that the invention attempts to solve]

Containers tailored to each of the above uses are effective in their own way, but they must be prepared separately for each type of cargo, which is uneconomical, and furthermore, it takes time to handle them, such as when using them effectively or storing them when not in use. There are drawbacks that require

Therefore, depending on the type of cargo, containers are required that can provide internal ventilation when necessary. In that case, it is desirable to have a configuration that allows internal ventilation to be performed quickly, and for this purpose, it is necessary to configure a plurality of ventilation holes.

The present invention has a structure in which the plurality of ventilation holes configured as described above can be opened and closed at the same time with a single touch, without having to open and close them individually.

[Means for solving problems]

This invention solves the above problems,
A group of ventilation holes are provided at appropriate intervals in the vertical direction at appropriate positions on the outer panel, and a cover with a ventilation hole at the bottom is provided on the outside of each group of ventilation holes. A rod is inserted through the bracket and can be moved up and down by an opening/closing handle provided on the container body side. Stoppers are fixed at appropriate intervals below the ventilation holes of each rod, and the stopper below A spring is fitted on each of the upper parts, and both ends of the damper are fitted between the spring and the upper stopper.

[Effect]

The drawings, except for FIG. 4, show the ventilation hole 5 in a closed state.

That is, the rods 9, 9a are raised, the spring 20 is compressed by the lower stopper 19, and the damper 21 is pressed into contact with the ventilation hole 5.

Next, when opening the ventilation hole 5, the opening/closing handle 8 is lowered.

As a result, the opening/closing lever 14 and the rods 9, 9a are lowered via the link 12, and the damper 21
is lowered from the ventilation hole 5 by the stopper 18 above the rods 9, 9a, and the ventilation hole 5 is opened.

When the ventilation hole 5 is kept open, the opening/closing handle 8 may be held by the hook 17.

Next, when closing the ventilation hole 5, remove the opening/closing handle 8 from the hook 17 and moving the opening/closing handle 8 upward, and the opening/closing lever 14 and the rods 9, 9a are raised via the link 12. , the damper 21 is raised by the action of the lower stopper 19 and the spring 20 and comes into contact with the ventilation hole 5, and when the opening/closing handle 8 is further moved to the hook 16 position, the damper 21 is brought into contact with the ventilation hole 5 and the rod is removed. 9, 9a and the stoppers 18, 19 fixed thereto are raised, and the lower stopper 19 compresses the spring 20 between it and the damper 21, so that the damper 21 more strongly pushes the ventilation hole 5.
It is pressed into contact with the pipe and is completely occluded.

〔Example〕

The drawings show one embodiment of the present invention, and FIG. 1 shows an example in which ventilation holes (ventilation equipment) are provided in the opening/closing doors 1 and 2 of the container body C. However,
It may be provided on the outer wall of the container body C.

First, as shown in FIGS. 2 and 4, the opening/closing door 1,
Ventilation hole groups 4, 4a, 4b... are provided at appropriate intervals in the vertical direction at appropriate positions of the outer panel 3 constituting the exterior panel 2. Covers 6, 6 with ventilation holes 5
a, 6b... are provided.

Next, on both sides of the covers 6, 6a, 6b..., there are brackets 7, 7a, 7 on the side of the container body C.
Rods 9, 9a are inserted through the rods 9, 7c, .

In the case of the embodiment shown in the drawings, the opening/closing handle 8 is an opening/closing handle support 1 erected on the upper surface of the cover 6b.
0 is fixed at its tip with a pin 11, and furthermore, a link 12 is connected at an appropriate position with a pin 13, and the lower end of the link 12 is connected with a pin 15 to an opening/closing lever 14 suspended and fixed between the rods 9 and 9a. ing.

Therefore, when the opening/closing handle 8 is moved up and down, the rods 9 and 9a are moved up and down.

Furthermore, there is an opening/closing handle 8 on the side of the container body C.
Hook 1 for holding in the upper and lower positions
6 and 17 are provided.

Furthermore, stoppers 1 are placed at appropriate intervals below the ventilation holes 5 of each of the rods 9 and 9a.
8 and 19 are fixed, and the stopper 19 below
A spring 20 is fitted above each, and both ends of a damper 21 are fitted between the spring 20 and the upper stopper 18.

In the case of the embodiment shown in the drawings, the damper 21 is made of U-shaped cross-sectional members 21 placed back to back, as shown in the fourth figure.
a, 21b, and a waterproof rubber 21c provided inside the upper U-shaped cross-sectional member 21a.
1c is configured to open and close the ventilation hole 5, and furthermore, only the lower U-shaped cross-sectional member 21b has rods 9, 9.
Only the lower U-shaped member 21b is fitted between the springs 20 of the rods 9, 9a and the upper stopper 18.

Therefore, when the opening/closing handle 8 is lowered,
The opening/closing lever 14 and the rods 9, 9a are lowered via the link 12, and the damper 21 is moved to the ventilation hole 5 by the stopper 18 above the rods 9, 9a.
The ventilation hole 5 is opened.

When the ventilation hole 5 is kept open, the opening/closing handle 8 may be held by the hook 17.

Next, in order to close the ventilation hole 5, remove the opening/closing handle 8 from the hook 17 and moving the opening/closing handle 8 upward. Then, the damper 21 is raised by the action of the stopper 19 and the spring 20 below the rods 9 and 9a, and comes into contact with the ventilation hole 5. After that, when the opening/closing handle 8 is further moved to the hook 16 position, the damper 21 is in contact with the ventilation hole 5, and the rod 9,
9a and stoppers 18, 19 fixed thereto
is raised, the lower stopper 19 compresses the spring 20 between it and the damper 21, and the damper 21 is more strongly pressed against the ventilation hole 5, completely closing it.

In the figure, 22 is a lining decorative board provided inside the container body C.

FIG. 5 shows the case where the opening/closing handle 8 is provided at the lowest position, and the other configurations are the same as the embodiment shown in FIG. 2 above.

[Effect of idea]

According to the present invention, a plurality of ventilation holes can be opened and closed with a single touch, making it easy to ventilate the interior and making it possible to use it according to the type of cargo.
