BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerating freezer for transportation, which is used for packing and transporting a large amount of refrigerated and frozen foods.

[0002]

2. Description of the Related Art A refrigerator / cooler commonly known as a cold roll box (CRB) is used as a box loaded on a freight vehicle for carrying refrigerated and frozen foods. Each storage space is constant, and from the economical point of view of storage of goods, the empty state of the entire volume when not in use does not do anything other than waste of space, and it is not considered effective. Not paid at all.

[0003]

[Problems to be Solved by the Invention] As described above, for a past transportation, a structurally fixed fixed volume housing occupies a specific space outside the opening / closing function of the door regardless of the presence or absence of the stored items. However, it is not possible to eliminate this uneconomical situation and to achieve a structure improvement means that reduces the predetermined space by improving the economic efficiency of the storage space by changing the disassembly of the housing when not in use. It is said that this is an important issue to be devised.

[0004]

SUMMARY OF THE INVENTION In this view, the present invention connects independent heat insulating panels having a housing structure that has never been conceived of in the past to openable and closable ones via connecting metal fittings and panel edges. The above-mentioned purpose was achieved by making the space tight by a heat insulating material through a heat insulating packing and insulating the inside and the outside, and making it possible to stabilize the assembly of each part panel of the housing, maintain the strength and disassemble the housing. Has been achieved.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings in the following embodiments.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view of the present invention, and FIG. 2 is a perspective view showing a state in which two housings whose doors are inverted in the side plate direction are stacked, and in FIG. An exploded view of each panel disassembly is shown.

The casing A is composed of a top plate 3, a bottom plate 4, a rear plate 5, left and right side plates 6 and 6, and a door 7. The panels (3 to 7) of each of these constituent parts respectively include the heat insulating material 1. It is covered with steel plate 2.

FIGS. 4 to 6 show joint relations between the respective panels, which can be opened and closed by being hinged to each other by a connecting fitting 8. One of both side plates 6 and 6 may be fixed.

Reference numeral 9 denotes an edge portion of each panel, and a sealing portion 11 made of a heat insulating material is formed through a heat insulating packing 10.

Reference numeral 12 denotes a panel fixing fitting that connects between the top plate 3 and the rear plate 5 and between the rear plate 5 and the side plate 6, and the relative angle can be adjusted. (See FIGS. 3 and 5)

Further, as shown in FIG. 6, the top plate 3 and the side plate 6 are rivet-attached to each other by a fixing metal fitting 13, and a claw 14 mounted on the top metal plate is engaged with a tip end portion of the metal fitting to fix both panels. Secure stable assembly.

Reference numeral 15 denotes a handle for opening and closing provided on the front surface of the door 7, and the door can be set to either a single-opening type or a double-opening type.

Since the present invention is configured as described above, when a predetermined article is stored in the housing A and is in a transporting state, the handle 15 of the door 7 is in the closed position and each panel (3 to 3). 7) are independent panels each having a heat insulating property, and they are hinged to each other by connecting metal fittings 8 and the panels to be joined are loosened in a joined state by locking the fixing metal fittings 12, 13 and the claws 14. Therefore, the panel edge portion 9 is formed of a heat insulating material to form the sealing portion 11, so that the refrigerating and freezing conditions of the stored articles are always maintained normal.

Since there are no items to be stored and the housing is stored when the case is not used, a space corresponding to the number of units is required. However, in the present invention, the panels are joined by the connecting fittings 8 having a hinge function. It can be opened and closed freely, and by stacking it on top of each other in a folded shape as illustrated in FIG. 2, the storage space is minimized, and it is easy to reuse.

[0015]

[Effect of the Invention] The present invention forms a housing in which panels are joined by a connecting metal fitting having a hinge function, facilitates movable assembly, and each panel itself has a heat insulating structure. The edges are also heat-insulated to keep the inside and outside airtight, and when the case is not in use, it can be folded and shrunk as appropriate by utilizing the disassembly and mobility of the connecting fittings and fixing fittings that have a hinge function to store the housing. The effect of improving the economical efficiency of the space is significant, and it has a practical effect that is not comparable to the existing similar products, such as the method of restoring the reuse being extremely easy and reliable.
