本発明は冷蔵庫等の断熱箱体に関し、特に網棚等の支持
を行うべく内箱に取付けられる支持具が確実かつ強固に
取付けられるようにしたものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating box for a refrigerator or the like, and in particular to a support that is attached to an inner box to support a net shelf, etc., so that it can be reliably and firmly attached.

向性が定まらないといった欠点があった。Conventionally, the mounting structure of the support in this type of insulation box is the third one.
There is one shown in the figure. In this figure, the support 6' passes through the through hole 6' of the inner box 3' and is fixed with a heat insulating material 4', but the support 6' is generally placed on the plane of the inner box 3'. Part 3
b' before filling with the heat insulating material 4'. When the insulating material 4' is injected from the injection port 8/ of the outer box 2', the insulating material 4' flows in the direction of the white line arrow, and then reacts as shown by the black line arrow, filling the space between the two boxes 21 and s1. be done. However, by making the portion where the support 5' is attached to the flat portion 3b', the vicinity of the extending portion 6b' of the support 5' becomes a recessed portion when viewed from the reaction direction of the heat insulating material 4'. Therefore, the extension part 5
b' cannot be completely filled with the insulation material 4-, and the support 6
Not only does the mounting strength of the support member 6b' not have sufficient strength, but the cavity A near the extending portion 6b' contracts as it cools, making it difficult to determine the directionality of the support member 6'.
本発明はかかる欠点を解消せんとして成されたものであ
り、以下その一実施例を添付図面に従い説明する。The present invention has been made to overcome these drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings.

り成る。In the figure, reference numeral 1 denotes a heat insulating box body of the refrigerator, which is composed of a metal outer box 2, a resin inner box 3, and a foamed heat insulating material 4, such as urethane, filled between these boxes 2 and 3. Reference numeral 6 denotes a support fixed to the slope 3a of the inner box 3, which protrudes into the main body 1 and serves as a shelf (
(not shown), and an extension portion 5b that is inserted through the through hole 6 of the inner box 3 into the space between the two boxes 2.3.

うじゃま板であり、一端は平坦面３ｂと同一方向の他の
面３ｂ’の裏面に固着されている。The vicinity of the through hole 6 of the inner box 3 for fixing the support 6 is a flat surface 3b, that is, the main body 1 in order to extend the support 6 at right angles.
It is designed in advance to form a plane parallel to the installation direction. Therefore, the periphery of the flat surface 3b constitutes the slope 3a. Reference numeral 7 designates a baffle plate that covers a position facing the extending portion 6b, and one end is fixed to the back surface of the other surface 3b' in the same direction as the flat surface 3b.

部６ｂ付近が完全に充填されることになる。In the above configuration, when injecting the heat insulating material 4 into the space between the boxes 2 and 3, the opening surface of the main body 1 should face downward, and the outer box 2
When the diurethane stock solution is injected through the injection port 8 formed on the back side of the diurethane, it flows downward as indicated by the white line arrow and accumulates, after which the reaction begins. That is, due to the reaction, it rises upward as shown by the black line arrow, but at this time, the baffle plate 7 is exposed to the heat insulating material 4 near the extension part 6b of the support 6, which is a concave part when viewed from the reaction direction (black line arrow). The foaming is absorbed, and as the foaming progresses, the concave portion acts as a urethane reservoir, and the area around the extending portion 6b is completely filled.

る。As is clear from the above description, according to the present invention, the heat insulating material is guided by the flange plate provided in the heat insulating material filling portion of the support and can be filled around the support in an even manner. It is possible to prevent the conventional disadvantages such as formation of a space in an insufficiently filled portion and deformation of the inner box due to contraction of this space.
