せずに収納しておくには「むろ」は有効であつ
た。(Problems to be solved by the invention) Conventional underfloor storage is for the above-mentioned purposes, so in cold regions, the interior becomes like a freezer in the winter, making it impossible to store vegetables. For this reason, for example, in Hokkaido, underground storage methods have traditionally been used in which a ``muro'' is built underground with concrete or wood and accessed using a ladder from under the floor, but access is cumbersome and water from melting snow flows in. There was a problem. However, in winter, ``Muro'' was effective for storing overwintering vegetables, fruits, sake, soy sauce, drinks, etc. without freezing them.

The outline is that it is an underfloor storage that is hung by fitting the supporting flange on the upper edge of a box-shaped box to the edge of a rectangular floor hole in a heated indoor room. and the opposite wall of the box,
A band-shaped steel plate reinforcing these is bent along the same groove shape around the outer periphery of the three groove-shaped sides consisting of the bottom, and both ends of the band-shaped steel plate are fixed to the support flange, and the thickness is adapted to the outer periphery of the box body. A box-shaped insulation material made of urethane foam with a diameter of 10 to 20 mm is placed in the box together with the steel strip.
This underfloor storage for cold regions is characterized by being covered up to the point where it touches the support flange.

寒気を遮断して庫内を凍結から守り得る。(Function) The storage cabinet of this invention has achieved the purpose of achieving the same anti-freezing effect as the above-mentioned ``Muro'' even in under-floor storage cabinets in ordinary households. In other words, the storage is a simple thin box made of rust-free metal plates in the shape of a box with a support collar attached, a steel band plate wrapped around it for reinforcement, and a thin urethane foam cover on the outside. Because it is covered with a thick layer, it is simple enough to be used as a household storage cabinet, and has an insulating effect that protects the interior from freezing even in the coldest months. Even if the urethane foam is only 10mm thick, it can block the cold air under the floor and protect the inside of the refrigerator from freezing during the severe cold season in Hokkaido.

補強用帯状鋼板は支持鍔から下げた溝形バンド
の形態で、薄板製収納庫に缶詰等、多量の食品を
入れた時、その重量の何割かを引受ける働きをす
る。しかし従来の板面補強のように板と補強材と
を固定する必要がないから、溶接、鋲等による板
の歪み、突出がなく、加工を要しない。 The reinforcing steel strip is in the form of a groove-shaped band hanging from the support collar, and when a large amount of food such as canned food is placed in the thin plate storage, it takes on a percentage of the weight. However, unlike conventional plate surface reinforcement, there is no need to fix the plate and the reinforcing material, so there is no distortion or protrusion of the plate due to welding, rivets, etc., and no machining is required.

しかもこの帯状鋼板は箱体外面に沿つているか
ら、収納庫外形寸法に合わせたウレタンフオーム
製カバーを、収納庫に引きかぶせるのに全く支障
がない利点も備える。 Moreover, since this strip-shaped steel plate runs along the outer surface of the box, it has the advantage that there is no problem at all when placing a urethane foam cover that matches the external dimensions of the storage over the storage.

の点で有利である。 In this embodiment, the strip-shaped steel plates 4 are attached to the collar 1 by crossing each other vertically and horizontally, but for example, two strips may be arranged in the same direction in parallel, or the width of one may be made narrower.
It is up to the designer to increase the number of pieces. Strip steel plate 4
In principle, there is no need for rivets to be attached to the box body 3, but in this embodiment only one rivet is used at the center of the bottom to prevent positional movement. Since the box body 3 is suspended by the band-shaped steel plate 4 fixed at both ends to the collar 1, there is no need to integrate the box body 3 and the band-shaped steel plate 4, which is advantageous in terms of appearance and required man-hours.

箱形断熱材５は保温効果のほか、帯状鋼板４を

た。 In addition, this idea has a unique reinforcing structure in which a strip-shaped thin steel plate is wrapped around the storage box body, and both ends are fixed to the support flange for hanging.This means that expensive rustless metal plates can be replaced with thin plates, and the box body can be reinforced. There is almost no welding distortion or protrusion of the rivet heads, which is common in other machines, and the reinforcing material does not protrude, so it has the advantage of being able to cover it with square-shaped urethane foam insulation that matches the outer shape of the storage compartment, and the hole in the floor into which it is sunk is also just a square. An added advantage is that a hole is sufficient.

この考案により、寒冷地では冬季、野菜等を収
