Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a technique effective when applied to a refrigerating and transporting box body, particularly to the structure of an interior plate provided inside the cargo compartment.

[Conventional technology]

BACKGROUND ART Conventionally, an interior plate, which is also called an inner lining or an inner liner, is provided inside a cargo room in a frozen transport box.

Then, in this type of interior plate, ribs or concave grooves protruding on the inner surface thereof are formed in order to effectively flow the cooling air around the load (for example, Japanese Utility Model Publication 4).
7-10648).

However, in the case of the conventional interior plate, since the ribs or concave grooves are formed continuously in the vertical direction, for example, in the horizontal direction, a square bar or a rope provided with locking tools at both ends is hung over to carry the load. If you install a load collapse prevention rail such as a lashing rail that has a large number of locking holes for fixing the load lock, the lashing rail will protrude inside the cargo room and interfere with the load, resulting in an effective load space. There is a problem of narrowing.

Therefore, an object of the present invention is to provide a refrigerating transportation box body having an interior plate that can prevent the cargo from interfering with the load even if a load collapse prevention rail such as a lashing rail is attached, and can effectively use the cargo space. It is in.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

[Means for Solving the Problems]

The following is a brief description of the outline of the typical invention disclosed in the present application.

That is, in the frozen transportation box body of the present invention, the inner plate of the box body has a plurality of ribs formed at predetermined intervals in the vertical direction so as to project inward of the box body. Discontinuities are provided between the ribs by making them discontinuous, and these discontinuities are formed linearly in the horizontal direction of the box,
It has a structure in which a load collapse prevention rail is attached to the linear discontinuous portion.

[Action]

According to the above-mentioned means, the load collapse prevention rail such as the lashing rail can be attached to the discontinuous portion of the rib, so that the lashing rail does not project to the inside of the interior plate beyond the rib. Therefore, it is possible to eliminate problems such as the lashing rails obstructing the load or reducing the effective load space.

〔Example〕

FIG. 1 (a) is a partial plan view of a part of an interior plate used in the frozen transport box body of the present invention, FIG. 1 (b) is a sectional view taken along the line IB-IB, and FIG. 2 is of the present invention. Fig. 3 is a schematic partial perspective view of the inside of the frozen transport box, Fig. 3 is a partial sectional view of the frozen transport box of the present invention, and Fig. 4 is a frozen transport box as an example of the frozen transport box of the present invention. It is the schematic seen from the back of a vehicle.

As an example, the refrigerating transport box 1 of this embodiment is embodied as a refrigerating transport vehicle 2 as shown in FIG. Both side walls 4 and 5 and a top wall (ceiling) 6 are provided. Of course, a refrigerating unit, a fan, etc. (not shown) are installed at the front of the refrigerating and transporting vehicle 2, and cold air from the refrigerating unit is supplied to the inside of the cargo compartment 7 and circulated. As shown in FIG. 3, the cargo bed 3, the side walls 4 and 5, and the top wall 6 each have a heat insulating material 8 inside to heat-insulate the inside and outside of the cargo room 7.

Further, on the floor surface of the loading platform 3, rails 9 for loading luggage are laid in the front-rear direction, and a gap for passing cold air is formed between the rails 9.

Further, inside plates 10 are provided inside the side walls 4 and 5. Inside the interior plate 10, a plurality of ribs 11 extending in the vertical direction, that is, the vertical direction, are formed by press molding.
It is provided so as to project inward in the loading chamber 7 at a predetermined interval. The ribs 11 are formed to ensure the flow of cold air even when a load is placed in the cargo room 7. The ribs 11 are arranged at predetermined intervals in the front-rear direction of the side walls 4, 5, that is, in the horizontal direction.

Further, the rib 11 is discontinuous in the vertical direction, that is, in the vertical direction, and in this example, is formed by being divided into three parts 11a, 11b, 11c. Therefore, these parts 11
Discontinuous portions 12a and 12b are formed between a and 11b and between 11b and 11c, respectively.

Since each of the discontinuous portions 12a and 12b of the present embodiment is formed at the same height position for each rib 11, each of the discontinuous portions 12a and 12b of the plurality of ribs 11 is connected to the side wall 4. , 5 are arranged horizontally in a straight line in the front-rear direction. In other words, since the portions 11a, 11b, 11c of the ribs 11 project inward from the inner surface of the interior plate 10, the discontinuous portions 12a, 12b have ribs 11a, 11b when viewed in the front-rear direction of the refrigeration transport vehicle 2. The portions 11a, 11b, and 11c look like grooves relatively recessed.

Therefore, as shown in FIGS. 2 to 4, a load collapse prevention rail such as a lashing rail 13 extending horizontally inside the side walls 4 and 5 is attached to the discontinuous portions 12a and 12b. However, the lashing rails 13 and the like do not protrude more than necessary toward the inside of the cargo room 7. In particular, if the thickness of the lashing rails 13 and the like is made smaller than the protruding amount of the ribs 11, the lashing rails 13 and the like can be prevented from projecting inward of the cargo compartment 7 than the ribs 11.

Further, since the lashing rails 13 provided on the discontinuous portions 12a and 12b also serve as the ribs 11 for securing the flow of the cool air at the same time, the discontinuous portions 12a and 12b are blocked by the cargo having a low height. There is no possibility that the flow of cold air will be blocked.

As a result, according to the present embodiment, it is possible to completely prevent the space of the loading chamber 7 from being narrowed by installing the load collapse preventing rail such as the lashing rail 13, or at least partially, that is, the height of the rib 11. Can only be reduced.

The invention made by the present inventor has been specifically described based on the embodiments, but the invention is not limited to the above-mentioned embodiments, and various modifications can be made without departing from the scope of the invention. There is no end.

For example, the number of discontinuous portions 12a and 12b of the rib 11 may be any number as long as it is one or more, and it is not necessary to form the discontinuous portion for all of the ribs 11, and only some of the ribs 11 may have discontinuous portions. May be formed.

The load collapse prevention rails attached to the discontinuous portions 12a and 12b of the rib 11 may be other than the lashing rails.

In the above description, the case where the invention made by the present inventor is mainly applied to the vehicle for frozen transportation, which is the field of use thereof, has been described, but the invention is not limited to this. For example, frozen transportation such as land and sea containers It can be widely applied to boxes.
