Description

[Detailed description of the invention] This invention relates to a shielding curtain for a freezer.More specifically, it is foldable and can be opened and closed freely, and small frozen items can be taken out without losing cold air when the curtain is closed. Its purpose is to create a shielding curtain.

Conventional freezer shielding curtains have been used by hanging wide, flexible plastic curtains, but especially when used in refrigerated vehicles, the frozen items inside could not be taken out unless the curtains were fully opened. Therefore, when opening and closing, cold air was lost and the temperature rose, which had a negative impact on the frozen goods loaded.

The present invention eliminates the above-mentioned defects and develops a shielding curtain that can freely provide openings according to the volume of loaded frozen goods and does not have more openings than necessary.

The structure of the present invention will be explained with reference to one embodiment according to the above-mentioned purpose.The structure is a foldable structure in which a thick film part 1 and a thin film part 2 made of flexible plastic are alternately connected by welding or integral molding. In the shielding curtain, thick film portions 1 located on the left and right of appropriate locations,
In place of the thin film part 2, a tongue-like thin film part 4 is welded or otherwise suspended between the thin film parts 1 and 2, and below the upper surface of the lower part of the tongue-like thin film part, the opposite edges 5, 5' of the thick film parts 1, 1 are formed. This is a shielding curtain for a freezer in which an appropriate number of opening/closing parts are provided, in which the opening/closing parts A are made to protrude so as to overlap with each other.

The present invention is constructed as described above, and will be further explained in detail with reference to the drawings. The thick film part 1 and the thin film part 2 made of plastic that do not lose flexibility due to a drop in temperature are arranged alternately, and a suitable length is extended from above. Until then,
Welded parts 3 or integrally molded in advance (FIGS. 1 and 2), tongue-like thin film parts 4 are integrally suspended from the thin film part 2 at appropriate locations, and the thick film parts 1 are attached to the upper surface of the tongue-shaped thin film parts 4. Protruding edges 5, 5' are provided protruding from the left and right sides of each (see Fig. 3), and the opening/closing portions A, which overlap and come into close contact with each other due to their elasticity, are provided with appropriate length and number as necessary, It is used for partitions inside the opening/closing doors of freezers in cold storage warehouses, refrigerated vehicles, etc.

In the front view of FIG. 3, the hatched portions represent welded portions.

The present invention has the following functions and effects due to the above-described configuration.

Since thick film parts 1 and thin film parts 2 made of flexible plastic are provided alternately, the folding can be opened and closed from both the left and right sides or the center as shown in FIG.
For the opening/closing part, an appropriate opening/closing mechanism such as a magnetic catch can be used. When used inside the opening/closing door of a refrigerated vehicle, etc., the protruding edges 5, 5' from the left and right sides of each thick film part 1 can be used without fully opening to take out a small amount of frozen food.
Open the opening/closing part A that is in close contact with the container and carry it out. The protruding edges 5, 5' return to their original positions due to their elasticity and come into close contact with each other.
The length of the opening/closing part A can be appropriately set in advance depending on the size of the frozen object. In addition, a tongue-shaped thin film part 4 is welded or suspended between the thick film parts 1 and 1 located on the left and right sides of the appropriate location in place of the thin film part 2, and below the upper surface of the lower part of the tongue-shaped thin film part, the above-mentioned Thick film part 1, 1
Since the opening/closing part A is constructed by protruding the opposing edges 5 and 5' so as to overlap each other,
The protruding edge 5 of the thick film part 1, 1 constituting the opening/closing part,
5' only overlap each other, and since the tongue-shaped thin film portion 4 is located on the top thereof, it can be freely bent and bent, and like the thin film portion 2, uniform bending is possible. Therefore, when the entire shielding curtain is folded and fully opened, each thin film part 2 and the opening/closing part A are similar and bend uniformly, and by providing the opening/closing part, only that part does not bend or protrudes outside. This will not cause the appearance to become unsightly.

Therefore, unlike the conventional method, there is no loss of cold air when the door is opened and closed, so there is no need to constantly operate the cooling device, and the invention is an extremely economical shielding curtain for a freezer.
