[Conventional technology]

This type of conventional refrigerator box with top table is
The configuration was roughly shown in FIGS. 7 to 9. To explain this briefly, reference numeral 1 denotes a refrigerator box body, which is formed by bending a steel plate material into a substantially U-shape, and includes left and right side plates 2, 2, a back plate 3 attached to the back side, and The ceiling part is provided with an outer box body consisting of a top table 4 etc. provided as a ceiling board, and inside thereof is formed a storage room (two rooms in this case) opened to the front side through a foam insulation material 5. Inner boxes 6, 6 are provided inside, and doors 7, 7 are provided on the front side of the outer box body to open and close each storage chamber formed by each inner box 6, respectively. There is.

By the way, as is clear from FIG. 8, the top table 4 constituting the outer case of the refrigerator box 1 described above has a front edge 8a facing inward in a U-shape and a rear edge 8b facing downward in an L-shape. The table plate 8 is made of a steel plate and is bent over the entire width in the width direction as a concave part 8c so that the central part becomes the article placement part 10. It is composed of attached edge members 9, 9. As shown in FIG. 9, these edge members 9, 9 are entirely made of a synthetic resin material, and have a flange portion 9a on the side that clamps both side edges of the table board 8, and a flange portion 9a opposite thereto. Support rib 9
b is formed in a horizontal U-shape,
Further, a lower flange portion 9c that clamps the upper end portion of the side plate 2 and a lower support rib 9d inside the lower flange portion 9c are formed in an inverted U shape on the lower side,
An appropriate gap (engaging groove) 9e is provided between each, and the mating member is configured to fit therein. In this case, the upper flange portion 9a of the edge member 9 described above is conventionally
As is clear from the drawings and FIG. 8, the central portion of the table plate 8 was formed in a concave shape corresponding to the concave portion 8c forming the article placement portion 10 of the table plate 8.

In addition, the ceiling portion 6a of the inner box 6, which faces the top table 4 via the heat insulating material 5, is inclined in the depth direction so as to meet the recess 8c in order to improve moldability during vacuum forming. The depth of the placing part 10 of the table board 8 is smaller than the ceiling part 6 of the inner box 6.
Care has been taken to ensure that the space between the wall and wall a is approximately uniform with the space on other wall surfaces, and the foamed heat insulating material 5 injected into this space is configured in an appropriate amount.

[Problem that the invention attempts to solve]

However, according to the top table 4 in the refrigerator box 1 configured as described above, the upper edge of the upper flange portion 9a of the edge member 9 is aligned with the recess 8c forming the article placement portion 10 at the center of the table plate 8. Since the section is also formed in a concave shape, when an unstable article is placed on the placing section 10, the article lacks stability, and the article may fall from the concave flange section 9a of the edge member 9 to the side of the refrigerator box 1. There was a risk of problems such as falling.

The present invention has been developed in view of the above-mentioned circumstances, and even when an unstable article is placed on the recess-shaped placing portion on the top table, the side edge of the top table It is an object of the present invention to provide a refrigerator box with a top table that can appropriately prevent articles from falling to the sides of the box.

[Means for solving problems]

According to the refrigerator box body with a top table according to the present invention, the recessed portion constituting the article placement portion is formed over the entire width and is fitted into the table plate which is bent in the front and back direction and its both side edges. In this top table, the edge member is provided with a flange portion that rises upward so that the portion corresponding to the recessed portion of the table plate becomes a stepped portion.

[Effect]

In the present invention, the flange portions of the edge members that are fitted to both side edges of the table plate have a flat shape that is unrelated to the article placement part that has a concave shape of the table plate. A step part is formed by the upper flange part of the edge member, and even if an unstable item is placed on it, it can be properly locked and held by the action of the step part. This can prevent it from falling to the side.

〔Example〕

Hereinafter, the present invention will be explained in detail using embodiments shown in the drawings.

1 to 3 show an embodiment of a refrigerator box with a top table according to the present invention,
In these figures, the above-mentioned figures 7 to 9
Parts that are the same as or correspond to those in the figures are given the same numbers and their explanations will be omitted.

Now, according to the present invention, the top table 4, which is disposed at the upper end of the left and right side plates 2, 2 which face each other and the back plate 3 provided on the back side thereof, and forms the top plate of the outer box body, A table board 8 in which a concave portion 8c constituting the article placement section 10 is formed over the entire width.
and an edge member 9 fitted to both side edges thereof, and the edge member 9 has a stepped portion 2 at a portion corresponding to the recess 8c of the table plate 8.
Upper side flange part 2 rising upward to become 1
It is characterized by the formation of 0.

That is, according to the present invention, the upper flange portions 20 of the edge member 9 fitted to both side edges of the table plate 8 are connected to the mounting portion 10 on the table plate 8 side.
It is formed in a flat shape unrelated to the recessed part 8c forming the mounting part 10, thereby forming a stepped part 21 surrounding both sides of the mounting part 10.

According to the above-described configuration, the table board 8
The article placement section 10 formed by the concave portion 8c has a concave shape surrounded by the flat portions on both end sides of the table plate 8 and the step portion 21 of the edge member 9, and is suitable for placing articles. Not only does this make the placement section 10 visually clear, but even if an unstable item is placed, the stepped portion 21 acts as a stopper to stably support it and prevent it from falling. It is possible to prevent problems that may occur.

Note that the present invention is not limited to the structure of the embodiment described above, and the shape, structure, etc. of each part may be modified or changed as appropriate. For example, in the embodiment described above, the stepped portion 21 of the edge member 9, which serves as a stopper for the article placement portion 10, is formed by the thick upper flange portion 20, but the present invention Not limited to this, the recess 8 of the table board 8

This can be prevented. In addition, the edge member 9
In order to ensure the strength at the portion where the long groove portion 30 is formed, as shown in FIG. 6, vertical ribs 31 may be formed within the long groove portion 30 at appropriate intervals. It should be obvious.

[Effect of idea]

As explained above, according to the refrigerator box with a top table according to the present invention, the table board is bent in the front-rear direction with the recessed part constituting the article placement part being formed over the entire width. In the top table, which forms the top plate of the outer box body by the edge members fitted to both side edges, the edge members are arranged so that the part corresponding to the concave part of the table plate becomes a stepped part. Since a rising flange is formed, despite the simple and inexpensive structure, the article placement area formed by the concave part of the table board is surrounded by flat parts on both ends of the table board and the stepped part of the edge member. This creates a concave shape surrounded by a concave area, which not only makes the placing area visually clear when placing an item, but also allows the above-mentioned effect even if an unstable item is placed. The stepped portion acts as a stopper and has various practical effects such as being able to stably support the step and appropriately prevent problems such as falling.
